The terms first, second and the like in the description and in the claims and in the above-described figures are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

It should be noted that, for convenience of explanation, like reference numerals denote like components in the embodiments of the present application, and detailed descriptions of the like components are omitted in the different embodiments for brevity.

Referring to fig. 1 to 4, an embodiment of the application provides a drawing device 100, which includes: support assembly 10, guide 30, and locking mechanism 50. The support assembly 10 comprises a first support 11 and a second support 13, the second support 13 being slidable relative to the first support 11 along a first direction (as indicated by arrow a in fig. 2), and the second support 13 having a first position (i.e., a closed state as shown in fig. 1), a second position (i.e., a first stretched state as shown in fig. 2), and a third position (i.e., a second stretched state as shown in fig. 3) relative to the first support 11, the second position being located between the first position and the third position; the guide piece 30 is slidably disposed on the first support piece 11 and is slidably connected with the second support piece 13, and is configured to drive the second support piece 13 to slide between a first position and a third position, and guide a sliding direction of the second support piece 13; the locking mechanism 50 is mounted on the support assembly 10, and when the second support member 13 is located at the second position or the third position, the locking mechanism 50 cooperates with the guide member 30 to lock the first support member 11 and the second support member 13; when the second supporting member 13 leaves the second position or the third position, the locking mechanism 50 cooperates with the guide member 30 to unlock the first supporting member 11 and the second supporting member 13, so that the second supporting member 13 can move relative to the first supporting member 11 under the action of the guide member 30, thereby changing the state of the drawing device 100 and adjusting the bearing area of the drawing device 100.

For convenience of description below, the drawing device 100 is defined as being in a closed state when the second support 13 is in the first position; when the second support 13 is in the second position, the drawing device 100 is defined to be in the first stretched state; when the second support 13 is in the third position, it is defined that the drawing device 100 is in the second stretched state.

The second support 13 moving away from the second or third position can be understood as: the second support 13 is located at other positions than the second position and the third position. For example, between a first position and a second position, or between a second position and a third position, etc.

Alternatively, the area of the first support 11 is larger than the area of the second support 13, for example, the width of the first support 11 is equal to the width of the second support 13 in a direction perpendicular to the first direction, and the first support 11 is larger than the width of the second support 13 in the first direction. Alternatively, when the second support 13 is in the first position, the second support 13 overlaps the first support 11 (i.e. when the first support 11 is disposed opposite the second support 13), the first support 11 covering the entire second support 13; when the second support 13 is located at the second position, the first support 11 is partially overlapped with the second support 13, and partially not overlapped; when the second support 13 is in the third position, the first support 11 and the second support 13 may partially overlap or may abut (i.e., not overlap). In other embodiments, the area of the first support 11 may be smaller than the area of the second support 13; alternatively, the area of the first supporting member 11 is equal to the area of the second supporting member 13, and the present application is not particularly limited.

Referring to fig. 5 to fig. 7, when the second supporting member 13 is located at the first position and the guiding member 30 slides along the first direction in a direction away from the first supporting member 11 (i.e. moves towards the third position), the guiding member 30 drives the second supporting member 13 to move along the direction away from the first supporting member 11, and when the second supporting member 13 moves at the second position, the locking mechanism 50 locks the first supporting member 11 and the second supporting member 13 under the action of the guiding member 30 to prevent the first supporting member 11 and the second supporting member 13 from moving relatively; when the guide member 30 continues to move from the second position in a direction away from the first support member 11 (i.e. continues to move toward the third position), the locking mechanism 50 releases the locking between the first support member 11 and the second support member 13 under the action of the guide member 30, so that the guide member 30 can drive the second support member 13 to move in a direction away from the first support member 11, and similarly, when the second support member 13 moves to the third position, the locking mechanism 50 locks the first support member 11 and the second support member 13 again under the action of the guide member 30, so as to prevent the first support member 11 and the second support member 13 from moving relatively. When the second support 13 is in the first position, the guide 30 is schematically engaged with the locking mechanism 50 as shown in fig. 5. When the second support 13 is in the second position, the guide 30 is schematically engaged with the locking mechanism 50 as shown in fig. 6. When the second support 13 is in the third position, the guide 30 is schematically engaged with the locking mechanism 50 as shown in fig. 7.

Conversely, when the second supporting member 13 is located at the third position and the third position moves toward the first position, the locking mechanism 50 releases the locking between the first supporting member 11 and the second supporting member 13 under the action of the guiding member 30, so that the guiding member 30 can drive the second supporting member 13 to move in a direction approaching to the first supporting member 11; when the second supporting member 13 moves to the second position, the locking mechanism 50 locks the first supporting member 11 and the second supporting member 13 under the action of the guiding member 30, so as to prevent the first supporting member 11 and the second supporting member 13 from moving relatively; when the guide member 30 continues to move from the second position toward the first support member 11 (i.e., toward the first position), the locking mechanism 50 releases the locking between the first support member 11 and the second support member 13 under the action of the guide member 30, so that the guide member 30 can drive the second support member 13 to move toward the first support member 11.

Optionally, when the second supporting member 13 is located at the first position, the second position, and the third position, the supporting assembly 10 has different bearing areas, so that the drawing device 100 has different bearing areas, and when applied to an electronic device, the flexible display screen of the electronic device can be switched between different exposed areas. In other words, when the second supporting member 13 is located at the first position, the second position, and the third position, respectively, the carrying areas of the drawing device 100 are different.

Specifically, when the second supporting member 13 is located at the first position, the drawing device 100 has a first bearing area, when the second supporting member 13 is located at the second position, the drawing device 100 has a second bearing area, and when the second supporting member 13 is located at the third position, the drawing device 100 has a third bearing area, where the first bearing area < the second bearing area < the third bearing area.

The drawing device 100 in the embodiment of the application includes a first support 11, a second support 13 and a guide 30, where the second support 13 can be located at a first position, a second position and a third position relative to the first support 11 under the action of the guide 30, so that when the second support 13 is located at different positions, the first support 11 and the second support 13 cooperate to form different bearing areas, and when the drawing device 100 is applied to an electronic device, and when a flexible display screen is arranged on the support assembly 10, the display area of the flexible display screen of the electronic device can be adjusted by adjusting the position of the second support 13 relative to the first support 11, so as to meet different requirements on the display area under different display conditions. In addition, the drawing device 100 further includes a locking mechanism 50, where the locking mechanism 50 is used to lock the first support member 11 and the second support member 13 when the second support member 13 is in the second position or the third position, so that the second support member 13 can be prevented from sliding or shaking relative to the first support member 11, which affects the display effect of the electronic device, and when the drawing device 100 falls or the support assembly 10 is impacted by an external force, the external force can be consumed between the support assembly 10 and the locking mechanism 50, so that the external force is prevented from being conducted to the guide member 30, the flexible display screen or other components that drive the guide member 30 to move, thereby affecting the stability and reliability of the adjustment of the display area of the electronic device. Furthermore, the guide member 30 and the locking mechanism 50 cooperate to realize multi-stage self-locking and self-unlocking of the first support member 11 and the second support member 13, so that no additional locking and unlocking control mechanism is required, and no manual operation is required.

In some embodiments, the locking mechanism 50 cooperates with the guide 30 to lock the first support 11 to the second support 13 when the second support 13 is in the first position. In other words, when the second supporting member 13 is at any one of the first position, the second position and the third position, the locking mechanism 50 cooperates with the guide member 30 to lock the first supporting member 11 and the second supporting member 13. In other embodiments, when the second support 13 is in the first position, the first support 11 and the second support 13 may not be locked, i.e. in an unlocked state (as shown in fig. 5).

Referring to fig. 4, in some embodiments, the number of second positions is 1. At this time, when the flexible display screen is disposed on the support assembly 10, the exposed area of the flexible display screen can be adjusted by adjusting the relative positions of the second support member 13 and the first support member 11, so that the flexible display screen has three display areas corresponding to the first position, the second position and the third position, respectively.

In other embodiments, the number of the second positions is a plurality (not shown), and when the number of the second positions is a plurality, a plurality of the second positions are disposed between the first position and the third position at intervals. At this time, when the flexible display screen is disposed on the support assembly 10, the exposed area of the flexible display screen can be adjusted by adjusting the relative positions of the second support member 13 and the first support member 11, so that the flexible display screen has more than four display areas, and more display areas can be selected. Compared with the electronic equipment with the size of the flexible display screen which can be changed between two sizes or three sizes, the electronic equipment can meet the requirements of more users and is suitable for more application scenes. For example, when the mobile phone is used in a mobile phone, the mobile phone pulling device 100 can be adjusted according to the size of the user's hand because the sizes of the different user's hands are different, so that the mobile phone pulling device 100 is more convenient for the user to hold, and when the user places the mobile phone, watches videos, images and the like, the flexible display can be adjusted to the maximum so as to have better visual effect. The term "plurality" in the present application means two or more.

Alternatively, the number of second locations may be, but is not limited to, 1, 2, 3, 4, 5, 6, etc. The number of the second positions can be determined according to the number of gear positions capable of realizing the self-locking function when the drawing device 100 realizes multi-stage self-locking.

Referring to fig. 8, in some embodiments, the second support member 13 has a limiting groove 131, a first supporting surface 133 and a second supporting surface 135 forming the limiting groove 131, the first supporting surface 133 and the second supporting surface 135 are disposed opposite to each other, and the guiding member 30 is partially slidably disposed in the limiting groove 131. When the guide member 30 moves in a direction away from the first support member 11, the guide member 30 moves in a direction approaching the first abutment surface 133 until the guide member 30 abuts against the first abutment surface 133, and the guide member 30 moves the second support member 13 together in a direction away from the first support member 11; when the guide member 30 moves toward the direction approaching the first support member 11, the guide member 30 moves toward the direction approaching the second abutment surface 135 until the guide member 30 abuts the second abutment surface 135, and the guide member 30 moves the second support member 13 together toward the direction approaching the first support member 11. By the action of the first abutment surface 133 and the second abutment surface 135, the relative sliding between the guide 30 and the second support 13 can be restricted between the first abutment surface 133 and the second abutment surface 135.

Referring to fig. 4 to 9, in some embodiments, the second support 13 includes a first support body 132, a second support body 134, and an adjusting member 136. The first support body 132 is connected with the second support body 134, the first support body 132 is slidably connected with the first support member 11, the second support body 134 faces the first support member 11 and protrudes out of the first support body 132, the second support body 134 has a communicating slot 137 and an adjusting slot 138, and the slot 137 is located on a surface where the second support body 134 is connected with the first support body 132, and is used for penetrating the guide member 30. The adjusting slot 138 penetrates the surface of the second supporting body 134 facing away from the first supporting member 11, and is used for setting the adjusting member 136 and part of the guiding member 30. The adjusting member 136 is fixed on a side of the second supporting body 134 facing away from the first supporting member 11 and is located in the adjusting groove 138, the adjusting member 136 and the second supporting body 134 enclose into the limiting groove 131, a surface of the adjusting member 136 facing the limiting groove 131 is the second supporting surface 135, and a surface of the second supporting body 134 facing the adjusting member 136 is the first supporting surface 133. The guide member 30 is slidably inserted into the slot 137, and after passing through the slot 137, is partially slidably disposed in the limiting slot 131.

In some embodiments, the distance L between the first abutment surface 133 and the second abutment surface 135 is between 2mm and 5mm, in particular, the distance L between the first abutment surface 133 and the second abutment surface 135 may be, but is not limited to, 2mm, 2.5mm, 2.8mm, 3mm, 3.1mm, 3.3mm, 3.5mm, 3.8mm, 4.0mm, 4.3mm, 4.5mm, 4.8mm, 5.0mm. If the distance between the first abutting surface 133 and the second abutting surface 135 is too small, when the guide 30 leaves the second position or the third position, the locking mechanism 50 may not be unlocked yet, the second support 13 is difficult to move relative to the first support 11, and the bearing area of the support assembly 10 cannot be changed, so that the bearing area of the drawing device 100 is changed, and when the drawing device 100 is applied to an electronic device, the display area of the flexible display screen of the electronic device is changed. When the distance between the first abutting surface 133 and the second abutting surface 135 is too large, the sliding space of the guide member 30 to be reserved is larger when the drawing device 100 is in the closed state, which increases the volume of the drawing device 100 in the closed state and is not beneficial to miniaturization of the drawing device 100.

Referring to fig. 10, in some embodiments, the drawing device 100 of the present application further includes a rail assembly 70, the rail assembly 70 extends along a first direction, and the rail assembly 70 includes a first rail member 71 and a second rail member 73 that are slidingly connected; the first rail member 71 is mounted to the first support member 11, and the second rail member 73 is mounted to the second support member 13 such that the second support member 13 is relatively movable with respect to the first support member 11 in a direction in which the rail assembly 70 extends. Through the cooperation of the first rail member 71 and the second rail member 73, when the second support member 13 moves relative to the first support member 11, the second support member 13 can slide in the first direction more stably, so that the relative offset between the second support member 13 and the first support member 11 is avoided, and the stability and the appearance effect of the drawing device 100 are affected.

In some embodiments, the first rail member 71 is a sliding rail, and the second rail member 73 is a sliding chute, as shown in fig. 10. The sliding track may be formed directly on the surface of the first support 11 facing the second support 13; in other words, the sliding rail and the first supporting member 11 are of an integral structure; or, the sliding rail and the first supporting piece 11 are of a split structure, and the sliding rail and the first supporting piece 11 are fixed by fixing pieces such as bolts and nuts. The chute may be formed on the second support 13; or the chute is formed on a rail member fixed to the second support member 13 by a fixing member such as a bolt, a nut, or the like. The sliding groove is in sliding fit with the sliding rail, so that when the second supporting piece 13 moves relative to the first supporting piece 11, the second supporting piece 13 can slide in the first direction more stably, and the second supporting piece 13 and the first supporting piece 11 are prevented from being offset relatively, so that the stability and the appearance effect of the drawing device 100 are prevented from being influenced. In addition, the structure is simple and convenient, and the slimness and thinness of the drawing device 100 are facilitated.

In other embodiments, the first rail member 71 is a chute and the second rail member 73 is a slide rail. The sliding track may be formed directly on the surface of the second support 13 facing the first support 11; in other words, the sliding rail and the second support 13 are of integral structure; or the sliding rail and the second supporting piece 13 are of a split structure, and the sliding rail and the second supporting piece 13 are fixed through fixing pieces such as bolts and nuts. The chute may be formed on the first support 11; or the chute is formed on a rail member fixed to the first support 11 by a fixing member such as a bolt, a nut, or the like. The sliding groove is in sliding fit with the sliding rail, so that when the second supporting piece 13 moves relative to the first supporting piece 11, the second supporting piece 13 can slide in the first direction more stably, and the second supporting piece 13 and the first supporting piece 11 are prevented from being offset relatively, so that the stability and the appearance effect of the drawing device 100 are prevented from being influenced. In addition, the structure is simple and convenient, and the slimness and thinness of the drawing device 100 are facilitated.

Referring to fig. 11 to 13, in some embodiments, the guide member 30 includes a main body 31, and the main body 31 includes at least two first guide portions 311 and at least two second guide portions 313, where the first guide portions 311 and the second guide portions 313 are sequentially and alternately arranged. When the guide 30 slides to the position where the first guide portion 311 is engaged with the locking mechanism 50, the locking mechanism 50 locks the first support 11 with the second support 13 under the action of the first guide portion 311, and when the guide 30 slides to the position where the second guide portion 313 is engaged with the locking mechanism 50, the locking mechanism 50 releases the locking between the first support 11 and the second support 13 under the action of the second guide portion 313. Through the cooperation of the first guiding part 311 and the second guiding part 313, when the second supporting piece 13 is driven to slide relative to the first supporting piece 11, the locking mechanism 50 is controlled to lock the first supporting piece 11 and the second supporting piece 13 when the locking is needed, and when the bearing area of the drawing device 100 needs to be adjusted, the locking mechanism 50 is controlled to release the locking of the first supporting piece 11 and the second supporting piece 13, so that the fineness and the reliability of the drawing device 100 are improved, and better experience is brought to a user.

Alternatively, the number of the first guide parts 311 may be, but not limited to, 2, 3, 4, 5, 6, etc. The number of the first guiding parts 311 determines the number of the support assembly 10 capable of performing multi-stage self-locking, namely, the number of the second positions, which is one less than the number of the first guiding parts 311, and the more the number of the first guiding parts 311, the more the number of the second positions.

Alternatively, the number of the second guide portions 313 may be, but not limited to, 2, 3, 4, 5, 6, etc. The second guide portion 313 may be determined according to the number of the first guide portions 311.

In the embodiment of fig. 11, the number of the first guide portions 311 and the second guide portions 313 is two, and in this case, the number of the second positions is 1. In the embodiment of fig. 12, the number of the first guide portions 311 and the second guide portions 313 is three, and in this case, the number of the second positions is 1. In the embodiment of fig. 13, the number of the first guiding portions 311 and the second guiding portions 313 is three, and at this time, the three first guiding portions 311 correspond to the first position, the second position and the third position, respectively; i.e. the number of second positions is 1, self-locking is also possible when the second support 13 is in the first position.

In some embodiments, when the guide 30 is slid from the position where the second guide 313 is engaged with the locking mechanism 50 to the position where the first guide 311 is engaged with the locking mechanism 50, the partial assembly of the locking mechanism 50 is biased in a second direction (shown by arrow B in fig. 10) toward a direction away from the guide 30, wherein the second direction is perpendicular to the first direction. In other words, when the guide 30 is slid to the position where the second guide 313 is engaged with the locking mechanism 50, the partial assembly of the locking mechanism 50 is entirely closer to the guide 30 than the position where the first guide 311 is engaged with the locking mechanism 50. Conversely, when the guide 30 is slid from the position where the first guide 311 is engaged with the locking mechanism 50 to the position where the second guide 313 is engaged with the locking mechanism 50, the partial assembly of the locking mechanism 50 is biased in a second direction toward a direction approaching the guide 30, wherein the second direction is perpendicular to the first direction. In this way, the guide member 30 controls part of the components of the locking mechanism 50 to move up and down in the second direction, so that unlocking and locking can be realized, the structure is simple and convenient, the control mechanism of the locking mechanism 50 is not required to be additionally arranged, and manual operation is not required to control the unlocking and locking.

In some embodiments, the first guiding portion 311 is a first guiding groove 311, the second guiding portion 313 is a second guiding groove 313, the number of the first guiding groove 311 and the number of the second guiding groove 313 are at least two, the number of the second guiding portion 313 is at least two, and the first guiding groove 311 and the second guiding groove 313 are sequentially and alternately arranged and are mutually communicated; the guide member 30 is slidably disposed in the mating groove 301 formed by the first guide groove 311 and the second guide groove 313; the width of the first guide groove 311 is greater than the width of the second guide groove 313 in a second direction perpendicular to the first direction. By arranging the guide grooves with different widths at different positions on the guide piece 30, when the guide piece 30 slides to different positions, the locking and unlocking of the locking mechanism 50 are controlled, so that the locking and unlocking of the first support piece 11 and the second support piece 13 are controlled, the structure is simple and convenient, the control mechanism of the locking mechanism 50 is not required to be additionally arranged, and the unlocking and locking are not required to be controlled by manual operation. In the embodiment of fig. 11, the number of the first guide grooves 311 is 2, the number of the second guide grooves 313 is 2, and the first guide grooves 311 and the second guide grooves 313 are alternately arranged in order and communicate with each other.

In some embodiments, the number of mating grooves 301 may be 1 or two. When the number of the fitting grooves 301 is two, the two fitting grooves 301 are disposed at intervals in the second direction.

In some embodiments, the maximum sliding distance L of the second support member 13 relative to the guide member 30 along the first direction satisfies the relationship l≡d, where d is the width of the first guide portion 311 along the first direction. In other words, the distance L between the first abutting surface 133 and the second abutting surface 135 is greater than or equal to the width of the first guide portion 311 in the first direction. In other words, the distance L between the first abutting surface 133 and the second abutting surface 135 is greater than or equal to the width of the first guide groove in the first direction. When the maximum sliding distance L between the second support member 13 and the guide member 30 is smaller than the width of the first guide portion 311 along the first direction, the guide member 30 already abuts against the first abutting surface 133 or the second abutting surface 135, and cannot slide against the second support member 13 any more, at this time, the locking mechanism 50 is still located at a position matching with the first guide portion 311, and the second guide portion 313 is not moved to a position matching with the locking mechanism 50, so that it is difficult to unlock the locking mechanism 50, and unlocking between the first support member 11 and the second support member 13 cannot be achieved.

Optionally, a maximum sliding distance L of the second support member with respect to the guide member along the first direction is in a range of 2 mm+.l+.5 mm. In particular, the maximum sliding distance L of the second support relative to the guide may be, but is not limited to, 2mm, 2.5mm, 2.8mm, 3mm, 3.1mm, 3.3mm, 3.5mm, 3.8mm, 4.0mm, 4.3mm, 4.5mm, 4.8mm, 5.0mm. The maximum sliding distance between the second support member and the guide member cannot be too small, if the maximum sliding distance between the second support member and the guide member is too small, the locking mechanism 50 may not be unlocked yet when the guide member 30 leaves the second position or the third position, the second support member 13 is difficult to move relative to the first support member 11, and the bearing area of the support assembly 10 cannot be changed, so that the bearing area of the drawing device 100 is changed, and when the drawing device 100 is applied to an electronic device, the display area of the flexible display screen of the electronic device is changed. When the maximum sliding distance between the second supporting member and the guide member is too large, the sliding space of the guide member 30 to be reserved is large when the drawing device 100 is in the closed state, which increases the volume of the drawing device 100 in the closed state and is not beneficial to miniaturization of the drawing device 100.

In some embodiments, the guide 30 further includes a supporting portion 33, where the supporting portion 33 is disposed at one end of the main body 31 and is connected to the main body 31 in a bending manner, and the supporting portion 33 is closer to an edge portion of the second support 13 than the main body 31; the supporting part 33 is slidably disposed in the limiting groove 131 of the second supporting member 13; when the guide 30 moves in a direction away from the first support 11, the abutting portion 33 moves in a direction approaching the first abutting surface 133 until the abutting portion 33 abuts against the first abutting surface 133 (as shown in fig. 14), and the guide 30 moves the second support 13 together in a direction away from the first support 11; conversely, when the guide 30 moves in a direction approaching the first support 11, the abutting portion 33 moves in a direction approaching the second abutting surface 135 until the abutting portion 33 abuts the second abutting surface 135 (as shown in fig. 15), and the guide 30 moves the second support 13 together in a direction approaching the first support 11. Through the cooperation of the supporting part 33 and the limiting groove 131, the guide piece 30 and the second support piece 13 can be in sliding connection, and the sliding distance is limited in the space of the limiting groove 131, so that the structure is simple and small.

Referring to fig. 16, in some embodiments, the locking mechanism 50 includes a locking component 51 and a limiting component 53, the locking component 51 is disposed on the first supporting member 11 and is slidably connected to the guiding member 30, the limiting component 53 is disposed on the second supporting member 13, and the locking component 51 cooperates with the limiting component 53 to lock or unlock the first supporting member 11 and the second supporting member 13. By matching the locking mechanism 50 with the guide member 30, the second support member 13 can lock the first support member 11 and the second support member 13 in the second position (as shown in fig. 17) and the third position (as shown in fig. 18), so as to prevent the second support member 13 from shaking relative to the first support member 11, and can well disperse the external force when being impacted or fallen by the external force, so that the external force is prevented from being conducted to the guide member 30, the flexible display screen or other components for driving the guide member 30 to move. In addition, when the bearing area needs to be adjusted, the locking assembly 51 and the limiting assembly 53 can be quickly unlocked through the cooperation of the guide piece 30, so that the structure is simple, convenient and small.

Referring to fig. 5 to 7, 17 and 18, further, when the locking assembly 51 is located at the first guiding portion 311, the locking assembly 51 is locked with the limiting assembly 53 under the action of the first guiding portion 311 to lock the first supporting member 11 with the second supporting member 13 (as shown in fig. 6, 7, 17 and 18), and when the locking assembly 51 is located at the second guiding portion 313, the locking assembly 51 is unlocked with the limiting assembly 53 under the action of the second guiding portion 313 (as shown in fig. 5) to unlock the first supporting member 11 with the second supporting member 13. Through the cooperation of the first guiding part 311 and the second guiding part 313, when the second supporting piece 13 is driven to slide relative to the first supporting piece 11, the locking assembly 51 is controlled to be clamped with the limiting assembly 53 to lock the first supporting piece 11 with the second supporting piece 13, and when the bearing area of the drawing device 100 is required to be adjusted, the locking assembly 51 is controlled to be separated from the limiting assembly 53 to unlock the first supporting piece 11 and the second supporting piece 13.

Further, when the guide 30 is slid from the position where the second guide 313 is engaged with the locking member 51 to the position where the first guide 311 is engaged with the locking member 51, the locking member 51 is biased in a second direction, which is perpendicular to the first direction, toward a direction away from the guide 30. In other words, the locking assembly 51 is entirely closer to the guide 30 when the guide 30 is slid to the position where the second guide 313 is engaged with the locking assembly 51 than the position where the first guide 311 is engaged with the locking assembly 51. In this way, the guide member 30 controls part of the locking assembly 51 to move up and down in the second direction, so that unlocking and locking can be realized, and the structure is simple and convenient, and manual unlocking and locking are not required.

Referring to fig. 19, alternatively, a vertical distance s1 between the first guiding portion 311 and the limiting component 53 is smaller than a vertical distance s2 between the second guiding portion 313 and the limiting component 53. In other words, the first guiding portion 311 is closer to the limiting component 53 than the second guiding portion 313, so that when the guiding member 30 reaches a position where the first guiding portion 311 is engaged with the locking component 51, the locking component 51 can be protruded in a direction away from the guiding member 30, and is clamped to the limiting component 53 to cooperate with the limiting component 53 to achieve locking, and when the guiding member 30 moves to a position where the second guiding portion 313 is engaged with the locking component 51, the locking component 51 can be offset in a direction close to the guiding member 30 to disengage from the limiting component 53 to achieve unlocking without adding an additional locking and unlocking control mechanism.

Referring to fig. 20 to 22, in some embodiments, the locking assembly 51 includes a locking member 511 and a guiding assembly 513, one end of the locking member 511 is connected to the guiding assembly 513, the other end of the locking member 511 is used for matching with the limiting assembly 53 to achieve locking and unlocking of the housing assembly 10, and an end of the guiding assembly 513 away from the locking member 511 is slidably connected to the guiding member 30. When the second supporting member 13 is located at the second position or the third position, under the action of the guiding member 30, the locking member 511 is clamped to the limiting component 53, so as to lock the first supporting member 11 and the second supporting member 13; when the second supporting member 13 leaves the second position or the third position, the guiding component 513 drives the locking member 511 to move towards the direction approaching the guiding component 30 under the action of the guiding component 30, so that the locking member 511 is separated from the limiting component 53, and unlocking of the first supporting member 11 and the second supporting member 13 is achieved. In other words, when the guide member 30 slides to a position where the first guide portion 311 is engaged with the guide assembly 513 (i.e. the guide assembly 513 is slidably connected with the first guide portion 311), the locking member 511 moves in a direction away from the guide member 30 to be clamped to the limiting assembly 53, so as to lock the first support member 11 and the second support member 13. When the guide member 30 slides to a position where the second guide portion 313 is engaged with the guide assembly 513 (i.e., the guide assembly 513 is slidably connected to the second guide portion 313), the locking member 511 moves toward the direction approaching the guide member 30 to disengage from the limiting assembly 53, so as to unlock the first support member 11 and the second support member 13.

It will be appreciated that the locking assembly 51 extends in a direction parallel to the second direction, in other words, the locking assembly 51 extends in a direction perpendicular to the direction of extension of the guide 30 (i.e. perpendicular to the first direction).

In some embodiments, the locking assembly 51 further includes an elastic member 515 and a positioning member 517, the elastic member 515 is sleeved on a portion of the locking member 511, the positioning member 517 is sleeved on the elastic member 515 and is fixed on a surface of the first supporting member 11 facing the second supporting member 13, the elastic member 515 is limited in the positioning member 517 by the positioning member 517 and the locking member 511, when the second supporting member 13 is located at the second position or the third position, under the action of the guiding member 30, the locking member 511 protrudes from the positioning member 517 and is clamped to the limiting assembly 53, so as to lock the first supporting member 11 and the second supporting member 13; when the second supporting member 13 leaves the second position or the third position, the guiding component 513 drives the locking member 511 to move towards the direction approaching the guiding member 30 and compress the elastic member 515 under the action of the guiding member 30, so that the locking member 511 is separated from the limiting component 53, and the first supporting member 11 and the second supporting member 13 are unlocked. Through the cooperation of locking piece 511, elastic component 515 and setting element 517, can be when elastic component 515 resumes deformation, locking piece 511 stretches out setting element 517 joint spacing subassembly 53, simultaneously, can compress elastic component 515 through the traction of guide assembly 513, makes locking piece 511 retract into setting element 517 to unblock, whole scheme simple structure, small and exquisite easily realizes.

Specifically, when the guide member 30 slides to a position where the first guide portion 311 is engaged with the locking member 51 (i.e., the second position or the third position), that is, when the first guide portion 311 is slidably connected with the locking member 51, since the first guide portion 311 is closer to the limiting member 53 than the second guide portion 313, the guide member 513 is closer to the limiting member 53 when in the position where it is engaged with the first guide portion 311, at this time, the elastic member 515 pushes the locking member 511 to move away from the guide member 30 under the elastic restoring force, protrudes out of the positioning member 517, and is engaged with the limiting member 53, and when the guide member 30 slides to a position where the second guide portion 313 is engaged with the locking member 51 (i.e., other than the second position or the third position, that is, when the second guide portion 313 is slidably connected with the locking member 51), the guiding member 513 moves in a direction close to the guide member 30, pulls the positioning member 517 together in a direction close to the guide member, and retracts into the positioning member, compressing the elastic member 515, so that the locking member 511 is disengaged from the limiting member 53, thereby unlocking the first support member 11 from the first support member 11.

It will be appreciated that the length of the resilient member 515 is greater when the guide 30 is in the position where the first guide portion 311 is in sliding engagement with the locking assembly 51 than when the guide 30 is in the position where the second guide portion 313 is in sliding engagement with the locking assembly 51. In other words, the elastic member 515 is compressed to a greater extent when the guide 30 is in the position in which the second guide portion 313 is in sliding engagement with the locking assembly 51 than when the guide 30 is in the position in which the first guide portion 311 is in sliding engagement with the locking assembly 51. That is, the elastic restoring force of the elastic member 515 when the guide member 30 is at the position where the first guide portion 311 is slidably engaged with the locking assembly 51 is greater than the elastic restoring force of the elastic member 515 when the guide member 30 is at the position where the second guide portion 313 is slidably engaged with the locking assembly 51.

Alternatively, the elastic member 515 may be in a relaxed state (i.e., not stretched or compressed) or in a compressed state when the first guide 311 corresponds to the locking assembly 51.

In some embodiments, the locking element 511 includes a locking portion 5111 and a supporting portion 5113 connected to each other, one end of the supporting portion 5113 away from the locking portion 5111 is connected to the guiding assembly 513, the elastic member 515 is sleeved on the supporting portion 5113 and abuts against the locking portion 5111, when the second supporting member 13 is located at the second position or the third position, under the action of the guiding member 30, the locking portion 5111 protrudes out of the positioning member 517 and is clamped to the limiting assembly 53, so as to lock the first supporting member 11 with the second supporting member 13; when the second supporting member 13 leaves the second position or the third position, the guiding assembly 513 drives the locking portion 5111 to move towards the direction approaching the guiding member 30 and compress the elastic member 515 under the action of the guiding member 30, so that the locking portion 5111 is separated from the limiting assembly 53, and the first supporting member 11 and the second supporting member 13 are unlocked. When the second supporting member 13 leaves the second position or the third position, the locking portion 5111 is received in the positioning member 517. By the cooperation of the locking portion 5111 and the positioning member 517, the elastic member 515 is limited in the positioning member 517 in both the extended and compressed states, and the locking portion 5111 can be driven to lock by the elastic restoring force of the elastic member 515, so that the structure is simple, small and easy to realize.

It is understood that the equivalent circular diameter of the cross section of the locking portion 5111 is greater than the equivalent circular diameter of the cross section of the supporting portion 5113 in the first direction. The term "equivalent circle diameter" in the present application refers to an irregular geometric figure that is the diameter of a circle of the same area.

Alternatively, in the first direction, the cross-sectional shape of the locking portion 5111 may be, but is not limited to, at least one of square (e.g., rectangular, square), round, quasi-square, quasi-round, etc., and the cross-sectional shape of the supporting portion 5113 may be, but is not limited to, at least one of square (e.g., rectangular, square), round, quasi-square, quasi-round, etc. The shape of the cross section of the locking portion 5111 may be the same as or different from the shape of the cross section of the supporting portion 5113. "square-like" refers to a square-like, e.g., square-like, rectangular-like, etc., structure with rounded corners, such as a rectangle. "circular-like" means that the cross-section is approximately circular, but not completely circular, e.g., with a small portion of the edge cut by a tangent, or with a small groove, etc.

In one embodiment, the cross-section of the locking portion 5111 is square with rounded corners and the cross-section of the supporting portion 5113 is circular along the first direction.

In some embodiments, the positioning member 517 has a receiving cavity 5171. The positioning element 517 has a first surface 5173 and a second surface 5175 opposite to each other along the second direction, the first surface 5173 is opposite to the second surface 5175 facing away from the guiding element 30, the accommodating cavity 5171 penetrates the first surface 5173 and the second surface 5175, the supporting portion 5113 of the locking element 511 penetrates the second surface 5175 after being inserted from the first surface 5173, and the elastic element 515 is accommodated in the accommodating cavity 5171.

Alternatively, the shape of the opening of the first surface 5173 may be the same as the shape of the cross section of the locking portion 5111 in the first direction, and the shape of the opening of the second surface 5175 may be the same as the shape of the cross section of the supporting portion 5113 in the first direction.

Optionally, the equivalent circle diameter of the opening of the second surface 5175 is smaller than the equivalent circle diameter of the opening of the first surface 5173, and the equivalent circle diameter of the opening of the first surface 5173 is smaller than the outer diameter of the elastic member 515. In one embodiment, the first surface 5173 is square in opening and the second surface 5175 is circular in opening.

Alternatively, the spring 515 may be, but is not limited to, a spring, an elastic sleeve, or the like. The elastic sleeve may be, but is not limited to, a rubber sleeve or a silicone sleeve, etc., and the present application is not particularly limited.

Referring to fig. 21 and 22 again, in some embodiments, the guide assembly 513 includes a guide 5131, a first connecting member 5133, a flexible member 5135, and a second connecting member 5137 sequentially connected, wherein an end portion of the guide 5131 away from the first connecting member 5133 is slidingly connected with the guide 30, an end portion of the second connecting member 5137 away from the flexible member 5135 is connected with the locking member 511, the first connecting member 5133 is used for fixedly connecting the guide 5131 with one end of the flexible member 5135, and the second connecting member 5137 is used for fixedly connecting the locking member 511 with the other end of the flexible member 5135. Further, the end of the guide 5131 away from the first connecting element 5133 is slidably disposed in the mating groove 301 formed by the first guiding groove 311 and the second guiding groove 313.

When the guide member 30 slides from the position where the second guide portion 313 is engaged with the locking assembly 51 to the position where the first guide portion 311 is engaged with the locking assembly 51 in the first direction, the guide member 5131 and the first connecting member 5133 move toward a position away from the guide member 30 in the second direction, the flexible member 5135 is loosened, and the locking member 511 moves toward a direction away from the guide member 30 under the elastic restoring force of the elastic member 515, so that the flexible member 5135 is always in a straightened state. When the guide member 30 slides from the position where the first guide portion 311 is engaged with the locking assembly 51 to the position where the second guide portion 313 is engaged with the locking assembly 51 in the first direction, the guide member 5131 and the first connecting member 5133 move toward the position close to the guide member 30 in the second direction, and the flexible member 5135 is pulled toward the direction close to the guide member 30, so that the locking member 511 is pulled to move toward the direction close to the guide member 30, and the elastic member 515 is compressed, and at this time, the flexible member 5135 is still in the straightened state. In addition, when the drawing device 100 falls or is impacted, the first supporting member 11 or the second supporting member 13 receives an external force, and the external force is only consumed between the first supporting member 11, the second supporting member 13, the locking member 511 and the limiting component 53 due to the existence of the flexible member 5135, so that the external force is not conducted to the guide member 30, the flexible display screen and other components for driving the guide member 30 to move, and damage of the external force to the guide member 30, the flexible display screen and other components for driving the guide member 30 can be better avoided, and the adjustment of the bearing area of the drawing device 100 is affected, so that the drawing device 100 has a longer service life and can be better and more stably adjusted.

Alternatively, the flexible member 5135 may be, but is not limited to, a member having flexibility, such as a rope, a flexible belt, e.g., a polyimide belt (PI belt), or the like, but not having elasticity.

Alternatively, the guide 5131 includes a slide shaft 5131a, and the slide shaft 5131a is slidably disposed in the fitting groove 301 of the guide 30.

Referring to fig. 23 and 24, in other embodiments, the guide assembly 513 includes a guide 5131, a first connecting member 5133, a first rod 5132, a second rod 5134, and a second connecting member 5137 sequentially connected, the first rod 5132 is rotatably connected to the first connecting member 5133, the first rod 5132 is rotatably connected to the second rod 5134, the second rod 5134 is rotatably connected to the second connecting member 5137, an end portion of the guide 5131 away from the first connecting member 5133 is slidably connected to the guide 30, and an end portion of the second connecting member 5137 away from the second rod 5134 is connected to the locking member 511. Alternatively, the first shaft 5132 and the second shaft 5134 are rotatably coupled by a rotation shaft or a bearing.

When the guide member 30 slides from the position where the second guide portion 313 is engaged with the locking assembly 51 to the position where the first guide portion 311 is engaged with the locking assembly 51 in the first direction, the guide member 5131 and the first connecting member 5133 move toward the position away from the guide member 30 in the second direction, so as to push the first rod 5132 and the second rod 5134 to rotate relatively, and the locking member 511 moves toward the direction away from the guide member 30 under the elastic restoring force of the elastic member 515, so that the first rod 5132 and the second rod 5134 are always in a straightened state (or on the same straight line). When the guide member 30 slides from the position where the first guide portion 311 is engaged with the locking assembly 51 to the position where the second guide portion 313 is engaged with the locking assembly 51 in the first direction, the guide member 5131, the first connecting member 5133 and the first rod 5132 move toward the position close to the guide member 30 in the second direction, and the second rod 5134 and the second connecting member 5137 pull the locking member 511 to move toward the direction close to the guide member 30 and compress the elastic member 515, and at this time, the first rod 5132 and the second rod 5134 are still in a straightened state (or on the same straight line). In addition, when the drawing device 100 falls or is impacted, the first support member 11 or the second support member receives an external force, and the first rod 5132 and the second rod 5134 are rotatably connected, so that the external force is only consumed between the first support member 11, the second support member 13, the locking member 511 and the limiting component 53, and the external force is not conducted to the guide member 30, the flexible display screen and other components for driving the guide member 30 to move, thereby better avoiding damage to the guide member 30, the flexible display screen and other components for driving the guide member 30 caused by the external force and affecting the adjustment of the bearing area of the drawing device 100, so that the drawing device 100 has longer service life and can perform the bearing area adjustment better and more stably.

Referring to fig. 5 to 7 again, in some embodiments, the limiting assembly includes a first limiting member 531 and a second limiting member 533, where the first limiting member 531 and the second limiting member 533 are mounted on a surface of the second supporting member 13 facing the first supporting member 11 along a direction parallel to the first direction at intervals; when the second supporting member 13 is located at the second position, the locking assembly 51 is locked to the first limiting member 531, so as to lock the first supporting member 11 with the second supporting member 13; when the second supporting member 13 leaves the second position, the locking assembly 51 is separated from the first limiting member 531, so that the first supporting member 11 is unlocked from the second supporting member 13; when the second supporting member 13 is located at the third position, the locking assembly 51 is locked to the second limiting member 533, so as to lock the first supporting member 11 with the second supporting member 13; when the second support 13 leaves the third position, the locking assembly 51 is disengaged from the second stopper 533 to unlock the first support 11 from the second support 13. Specifically, when the second supporting member 13 moves from the first position to the second position, the locking member 511 is partially located between the first limiting member 531 and the second limiting member 533, and abuts against the first limiting member 531 to prevent the second supporting member 13 from sliding relative to the first supporting member 11, so as to lock the first supporting member 11 and the second supporting member 13; when the second supporting member 13 moves from the second position to the third position, the locking assembly 51 is separated from the first limiting member 531, so that the first supporting member 11 is unlocked from the second supporting member 13; when the second supporting member 13 is located at the third position, the locking member 511 is located at a side of the second limiting member 533 away from the first limiting member 531, and abuts against the second limiting member 533 to lock the first supporting member 11 with the second supporting member 13; when the second support member 13 moves from the third position to the first position or the second position, the locking assembly 51 is disengaged from the second stopper 533 to unlock the first support member 11 from the second support member 13.

When it is desired to lock the locking assembly 51, the first support 11 may be locked with the second support 13 by providing a groove in the surface of the second support 13 facing the first support 11, when the locking member 511 is inserted into the groove, and when the locking member 511 is separated from the groove, the first support 11 is unlocked from the second support 13, but when the locking assembly 51 is locked by providing a groove in the second support 13, the first support 11 is firmly locked with the second support 13, and the groove needs to have a certain depth, and the second support 13 needs to have a sufficient thickness, which makes the second support 13 heavy. In addition, the first supporting member 11 and the second supporting member 13 are usually aluminum alloy supporting members, which have low hardness and are not collision-resistant, and if grooves are directly formed on the aluminum alloy supporting members to lock the locking assembly 51, after a period of use, the positions of the grooves of the second supporting member 13 are easy to deform, so that the locking stability of the locking assembly 51 is reduced. Through setting up first locating part 531 and second locating part 533 on second support piece 13, need not to open a groove on second support piece 13, consequently, second support piece 13 can be made thinner, and is lighter, and first locating part 531 and second locating part 533 can adopt crossing aluminum alloy to have the locating part of higher hardness, even in this way through a period of use, can not take place the deformation because of being impacted, can lock first support piece 11 with second support piece 13 more firmly, more accurately.

Alternatively, when the number of the second positions is plural, the number of the second limiting members 533 is plural, and the plurality of second limiting members 533 are disposed at intervals along the first direction, and the number and the positions of the first guiding portions 311 are in one-to-one correspondence.

Alternatively, the first stopper 531 has a hardness greater than that of the second support 13, and the second stopper 533 has a hardness greater than that of the second support 13. In an embodiment, the first supporting member 11 and the second supporting member 13 are made of aluminum alloy, and the first limiting member 531 and the second limiting member 533 are made of stainless steel.

Alternatively, the first limiting member 531 is fixed to the second supporting member 13 by a fixing member such as a screw, a bolt, or the like. The second limiting member 533 is fixed to the second supporting member 13 by a fixing member such as a screw, a bolt, a screw, or the like.

Alternatively, the distance between the first stopper 531 and the second stopper 533 is greater than the width of the first guide 311 in the first direction. When the distance between the first limiting member 531 and the second limiting member 533 is too close, unlocking between the locking assembly 51 and the limiting assembly 53 is affected. In this way, the locking assembly 51 and the limiting assembly 53 can be unlocked more smoothly, and the situation that unlocking cannot be performed is avoided.

In some embodiments, when the number of the mating grooves 301 is two, and the two mating grooves 301 are arranged at intervals along the second direction, the number of the locking mechanisms 50 is also two, and the two locking mechanisms 50 are respectively arranged at two opposite sides of the guide member 30 along the second direction, each locking mechanism 50 is mated with one mating groove 301, and different locking mechanisms 50 are mated with different mating grooves 301, so as to jointly achieve locking and unlocking between the first support member 11 and the second support member 13.

Referring to fig. 1 to 4 and 25, in some embodiments, the drawing device 100 further includes a driving mechanism 90, where the driving mechanism 90 is mounted on the first supporting member 11 and connected to the guiding member 30, and is used for driving the guiding member 30 to move back and forth in the first direction, so as to drive the second supporting member 13 to move back and forth between the first position and the third position relative to the first supporting member 11, so as to adjust the bearing area of the drawing device 100.

Referring to fig. 25 and 26, in some embodiments, the driving mechanism 90 includes a driving motor 91, a first screw 93 and a second screw 95. The driving motor 91 is disposed on the surface of the first supporting member 11 facing the second supporting member 13, the driving motor 91 is connected with the first screw member 93, and is used for driving the first screw member 93 to rotate (such as clockwise or anticlockwise), the first screw member 93 extends along a first direction and has an external thread, the second screw member 95 has an internal thread, the second screw member 95 is screwed to the outer periphery of the first screw member 93, and the second screw member 95 is fixedly connected with the guide member 30. When the driving motor 91 is turned on, the driving motor 91 drives the first screw member 93 to rotate, so as to drive the second screw member 95 to move along the first direction toward the direction approaching or separating from the driving motor 91, and further drive the guide member 30 to move along the first direction toward the direction approaching or separating from the driving motor 91, and then drive the second support member 13 to move along the first direction toward the direction approaching or separating from the first support member 11. The cooperation of the driving motor 91, the first screw connector 93 and the second screw connector 95 converts the rotation motion of the driving motor 91 into the linear motion of the second screw connector 95, so that the size and structure of the driving mechanism 90 can be simplified better, and the miniaturization and ultra-thin of the drawing device 100 in the closed state are facilitated.

In one embodiment, the first threaded member 93 is a screw or a lead screw and the second threaded member 95 is a nut.

In some embodiments, the driving motor 91 includes a power output shaft 911, and the driving mechanism 90 further includes a transmission assembly 97, where the transmission assembly 97 is sleeved on the power output shaft 911 and sleeved on the first screw member 93, and is used to transmit the rotational motion of the power output shaft 911 to the first screw member 93.

Since the first screw 93 is generally longer, if the power output shaft 911 of the driving motor 91 is directly connected to the first screw 93, the driving mechanism 90 may have a longer length along the first direction, which is not beneficial to reducing the width of the pulling device 100 in the closed state along the first direction. By the cooperation of the four engagement members, the driving motor 91 can be arranged at the side edge of the first screw member 93, so that the width of the drawing device 100 in the first direction when in the closed state is reduced, and the drawing device 100 has smaller size when in the closed state and is convenient to carry.

Optionally, the first engaging member 971, the second engaging member 973, the third engaging member 975 and the fourth engaging member 977 are gears. In a specific embodiment, the first engaging member 971 and the fourth engaging member 977 are single-layer gears, the second engaging member 973 and the third engaging member 975 are double-layer gears, and the power of the driving motor 91 can be more precisely transmitted to the first screw member 93 through the cooperation of the single-layer gears and the double-layer gears, so that the adjusting process of the bearing area of the drawing device 100 is more stable and precise. The double-layer gear is provided with two gears which are coaxially arranged and have different diameters of the addendum circle or the dedendum circle.

In some embodiments, the driving mechanism 90 further includes a mounting frame 92, where the mounting frame 92 is disposed on a surface of the first support 11 facing the second support 13, for mounting the driving motor 91, the first screw 93, the second screw 95, and the transmission assembly 97.

In some embodiments, the driving mechanism 90 further includes a guide rod 94, the guide rod 94 is mounted on the mounting frame 92, the guide rod 94 is spaced from the first screw member 93 and extends along the first direction, and the second screw member 95 is further slidably sleeved on the guide rod 94. The guide rod 94 is used to make the second screw member 95 slide back and forth in the first direction more smoothly, so as to avoid the second screw member 95 from rotating during the sliding process, and thus the guide member 30 can slide in the first direction smoothly.

Alternatively, the number of the guide rods 94 may be one or two, and when the number of the guide rods 94 is two, the two guide rods 94 are disposed at opposite sides of the first screw 93 at intervals, respectively.
