Referring to fig. 1 and 2, an electronic device 100 provided in the embodiments of the present application may be a mobile phone or a tablet computer, which is not limited herein.
The electronic device 100 includes a housing assembly 10 and a flexible screen 20. The housing assembly 10 forms a receiving chamber 10a, and the flexible screen 20 is connected to the housing assembly 10. The electronic device 100 may further include a circuit board (not shown) and a battery (not shown), both of which may be disposed within the receiving cavity 10a of the housing assembly 10. The circuit board may integrate the processor, power management module, memory unit, baseband chip, etc. of the electronic device 100. The flexible screen 20 is communicatively coupled to the processor and a battery is capable of powering the flexible screen 20 and the electronic components on the circuit board. Of course, the electronic device 100 may further include a camera module (not shown), where the camera module is communicatively connected to the circuit board, and the battery can supply power to the camera module. It is understood that the electronic device 100 according to the embodiment of the present application includes, but is not limited to, a terminal device such as a mobile phone, a tablet computer, or other portable electronic devices 100. In the embodiment of the present application, a mobile phone will be described as an example.
As seen in fig. 3 and 4, the housing assembly 10 includes a first housing 12 and a second housing 14, the second housing 14 and the first housing 12 being capable of relative movement in a first direction. Specifically, in the present embodiment, the second housing 14 and the first housing 12 are slidably connected. In other words, the second housing 14 is capable of sliding relative to the first housing 12. For example, one of the first and second housings 12 and 14 may be provided with a slide rail along which the other can slide to enable the first and second housings 12 and 14 to move telescopically with each other.
The flexible screen 20 is connected to the first housing 12 and the second housing 14. With the relative movement of the first and second housings 12, 14, a portion of the structure of the flexible screen 20 is either deployed from within the housing assembly 10 or is stowed within the housing assembly 10 for the purpose of adjusting the deployment length of the flexible screen 20.
Further, the second housing 14 is slidable in a first direction relative to the first housing 12 to a stowed position and a deployed position. As shown in fig. 1 and 2, the electronic device 100 has a relatively small external dimension when the second housing 14 is in the folded position, and is convenient to carry. As shown in fig. 3 and 4, when the second housing 14 is in the unfolded position, the electronic device 100 can obtain a relatively large display area, so as to obtain a visual experience of a large screen display, so as to improve the use experience of the electronic device 100. Thus, with this arrangement, the area of the display screen of the flexible screen 20 (hereinafter referred to as the display interface 20 a) can be adjusted by relative sliding expansion and contraction of the first housing 12 and the second housing 14.
It should be noted that, as a structural member of the electronic device 100 for displaying or touching, the flexible screen 20 has a display area, where the display area corresponds to an area of the flexible screen 20 corresponding to a maximum display screen, or when the first housing 12 and the second housing 14 are in the extended position during the sliding and stretching process, that is, when the display interface 20a is at a maximum, the display interface 20a is the same as the display area. Since the portion of the display area of the flexible screen 20 is housed inside without being exposed during the sliding expansion and contraction of the first housing 12 and the second housing 14 with respect to each other, this portion does not take a display screen. The display interface 20a refers to a portion of the display area exposed to the first housing 12 and the second housing 14. When the display interface 20a is turned on or the screen is displayed, the content displayed on the display interface 20a can be observed by the outside of the electronic device 100.
It is to be understood that in the embodiments described hereinafter, the collapsed position, the extended position, and the like refer to the relative positions of the second housing 14 and the first housing 12. For simplicity, similar expressions of "the second housing 14 is in the collapsed position" or "in the collapsed position" refer to the second housing 14 being in the collapsed position relative to the first housing 12, and similar expressions of "the second housing 14 is in the deployed position" or "in the deployed position" refer to the second housing 14 being in the deployed position relative to the first housing 12.
As shown in fig. 2 and 4, the flexible screen 20 may include a fixed portion 202 and a free portion 204 disposed opposite to each other, where the fixed portion 202 is disposed on the first housing 12 and is fixed relative to the first housing 12. When the second housing 14 is in the folded position, the free portion 204 of the flexible screen 20 is accommodated in the case assembly 10, so that a part of the structure of the flexible screen 20 is hidden in the case assembly 10, and the part of the flexible screen 20 hidden in the case assembly 10 may not be used for display. In other words, movement of the first housing 12 relative to the second housing 14 may cause at least a portion of the free portion 204 to be deployed in the second housing 14 or the free portion 204 deployed in the second housing 14 to be received within the housing assembly 10.
It will be appreciated that in the embodiments of the present application, the positions of the two objects are relatively fixed, that is, the two objects cannot generate relative motion under normal conditions, and the two objects with relatively fixed positions may be directly connected physically, or may be indirectly connected through an intermediate structure. Taking the fixing portion 202 and the first housing 12 as examples, the positions of the fixing portion 202 and the first housing 12 may be fixed relatively, for example, the fixing portion 202 and the first housing 12 may be in direct contact, for example, the fixing portion 202 and the first housing 12 may be directly fixed by a threaded fastener or a clamping manner, or the fixing portion 202 may be indirectly fixed to the first housing 12 by a structure such as an adhesive layer or an intermediate connection plate.
It will be appreciated that the fixed portion 202 and the free portion 204 can be distinguished in the following manner, and referring to fig. 2, when the second housing 14 is in the folded position relative to the first housing 12, the portion of the flexible screen 20 exposed outside the housing assembly 10 is the fixed portion 202 of the flexible screen 20, and the portion of the flexible screen 20 accommodated in the housing assembly 10 can be regarded as the free portion 204. In some embodiments, when the second housing 14 is in the folded position, the fixing portion 202 exposed outside the housing assembly 10 is generally rectangular, and its size may be 4.5 inches to 7 inches, which is equivalent to the size of the display screen of a typical smart phone, so that the electronic device 100 is convenient to carry and use.
In some embodiments, as shown in connection with fig. 4, the electronic device 100 is provided with a traction member 30, where the traction member 30 is disposed at an end of the second housing 14 away from the first housing 12, and during the process of switching the second housing 14 from the folded position to the unfolded position relative to the first housing 12, the traction member 30 may draw the flexible screen 20 to deform so that a portion of the flexible screen 20 unfolded from the second housing 14 is flat. When the second housing 14 is in the folded position, the free portion of the flexible screen 20 bypasses the traction member 30, and the traction member 30 can limit the bending radius of the flexible screen 20 within a proper range, so as to avoid damage to the flexible screen 20 caused by too small bending radius. Of course, the traction member 30 can also avoid the excessive thickness of the electronic device 100 caused by the excessive bending radius of the flexible screen 20.
In some embodiments, the traction member 30 may be a rotating shaft structure with teeth, and the flexible screen 20 is coupled with the traction member 30 by engagement or the like. When the second housing 14 slides relative to the first housing 12, the traction member 30 moves the portion of the flexible screen 20 engaged with the traction member 30 and is extended from the housing assembly 10 or retracted into the housing assembly 10.
In other embodiments, the traction members 30 are circular shafts without accompanying teeth. During the process of switching the second housing 14 from the folded position to the unfolded position, the traction member 30 is used to prop open the part of the flexible screen 20 attached to the traction member 30, so that more flexible screen 20 is exposed to the outside of the housing assembly 10 and is in the unfolded position. In this embodiment, the traction member 30 may be rotatably disposed on the second housing 14, and the traction member 30 may rotate with the movement of the flexible screen 20 during the gradual deployment of the flexible screen 20, so as to reduce the resistance of the flexible screen 20 during the deployment and reduce the abrasion of the contact portion of the traction member 30 and the flexible screen 20.
In some embodiments, the traction member 30 may also be fixed to the second housing 14, the traction member 30 having a smooth surface. The traction member 30 is slidably contacted with the flexible screen 20 through a smooth surface thereof during the process of expanding the flexible screen 20 to the second housing 14. In other words, in such an embodiment, the traction member 30 may be integrally formed with the second housing 14 or welded, and the traction member 30 may be considered as a portion of the second housing 14, with the free portion 204 of the flexible screen 20 bypassing an end of the second housing 14 remote from the first housing 12 and extending into the housing assembly 10.
During the process of switching the second housing 14 from the folded position to the unfolded position, the flexible screen 20 can be unfolded from the second housing 14 or retracted into the housing assembly 10 under the driving of the traction member 30. It can be appreciated that a plurality of intermediate positions may also be disposed between the folded position and the unfolded position, so as to position the second housing 14 relative to the first housing 12 at the plurality of intermediate positions, and enable the flexible screen 20 to have different display areas at different intermediate positions, thereby expanding the usage scenario of the electronic device 100.
The relative movement of the first housing 12 and the second housing 14 of the electronic device 100 may be accomplished manually or electronically.
For example, when the first housing 12 and the second housing 14 are manually held by a user, the second housing 14 may be placed in the deployed position when the user moves in a direction away from each other. Accordingly, when the second housing 14 is in the unfolded position, the electronic device 100 is only required to be folded when the first housing 12 and the second housing 14 are moved in a direction approaching each other.
As shown in connection with fig. 2 and 4, a drive mechanism 40 may be provided within the housing assembly 10 of the electronic device 100 when electronically controlled. Specifically, the driving mechanism 40 is disposed in the accommodating cavity 10a of the housing assembly 10, and is used for driving the first housing 12 and the second housing 14 to relatively move, so that the second housing 14 drives the flexible screen 20 to be unfolded from the housing assembly 10 or to be retracted into the housing assembly 10.
In some embodiments, the first housing 12 and the second housing 14 are connected to the driving mechanism 40 and move relatively under the driving of the driving mechanism 40. Specifically, the driving mechanism 40 has a fixed portion and a movable portion, and the movable portion is movable relative to the fixed portion when the driving mechanism 40 is operated. The fixed portion is connected with the first housing 12, and the movable portion is connected with the second housing 14 and is used for driving the second housing 14 to move relative to the first housing 12.
The second housing 14 may also include a rear cover 14a, the rear cover 14a covering the free portion 204 of the flexible screen 20 in the deployed position.
Further, the rear cover 14a may be provided with a light-transmitting area, and the portion of the flexible screen 20 that is received in the housing assembly 10 in the unfolded position may also be used for displaying, so that a user can view information displayed on the flexible screen 20 from the light-transmitting area, and further expand the usage scenario of the electronic device 100. For example, in this embodiment, the electronic device 100 can realize functions such as self-timer, video call, and the like by using a rear camera module without providing a front camera. The light-transmitting region may be made of transparent glass or may be formed by opening the rear cover 14 a. After the second housing 14 slides to the retracted position relative to the first housing 12, at least a portion of the flexible screen 20 housed in the housing assembly 10 is exposed. The exposed flexible screen 20 may be used for display such that the electronic device 100 has a relatively large display area to enhance the user's use experience.
Referring to fig. 5, the electronic device 100 includes a screen support assembly 50, where the screen support assembly 50 is used for supporting a portion of the flexible screen 20 that extends out from the housing assembly 10, so that the display interface 20a of the flexible screen 20 maintains good flatness, and the texture of the display screen is improved.
Specifically, as shown in connection with fig. 6 and 7, the screen support assembly 50 includes a first support 51, a second support 52, and a slip fit 53.
The first supporting member 51 is provided with a plurality of slots 511, and the plurality of slots 511 extend along a first direction (i.e. the direction of the flexible screen 20 moving along with the housing assembly 10) and are arranged parallel to each other along a second direction, wherein the second direction is perpendicular to the first direction.
The second supporting member 52 includes a spine 521 and a plurality of frames 522 connected to the spine 521, the frames 522 are arranged in a comb shape, and the frames 522 are movably inserted into the slots 511. Because slot 511 extends in the first direction, backbone 522 may move in the first direction within slot 511 to allow relative movement of first support 51 and second support 52 in the first direction as flexible screen 20 moves telescopically with housing assembly 10 in the first direction to accommodate the need to support the portion of flexible screen 20 that is being extended from housing assembly 10.
The first support 51 is fixed relative to the first housing 12 and the spine 521 is fixed relative to the second housing 14 such that the backbone 522 on the spine 521 moves with the second housing 14. Thus, when the first housing 12 and the second housing 14 move relatively along the first direction, the skeleton 522 moves along the first direction relative to the first supporting member 51 under the driving of the second housing 14, and then the skeleton 522 moves along the corresponding slot 511, so as to provide support for the flexible screen 20.
It should be noted that, the arrangement of the flexible screen 20 with respect to the first support member 51 and the second support member 52 has a plurality of possibilities. For ease of understanding, the manner in which flexible screen 20 is disposed will be described below with reference to flexible screen 20 having fixed portion 202 and free portion 204.
As shown in fig. 5 and 6, the fixing portion 202 is connected to the first support 51, and the free portion 204 surrounds a side of the second support 52 adjacent to the spine 521 and is movable relative to the second support 52 with the relative movement of the first and second housings 12 and 14, so that the first and second supports 51 and 52 can always support the components of the flexible screen 20 that are being extended from the housing assembly 10 when the flexible screen 20 is extended or retracted with the relative movement of the first and second housings 12 and 14.
Based on the relative fixation of the first support 51 to the first housing 12 and the relative fixation of the spine 521 to the second housing 14, the relative movement of the first housing 12 and the second housing 14 in the first direction enables the relative movement of the first support 51 and the second support 52 in the first direction such that the free portion 204 may also wrap around the screen support assembly 50 from the other side instead of wrapping around one side of the second support 52 adjacent to the spine 521. Specifically, the fixed portion 202 is connected to the second support 52, and the free portion 204 surrounds the side of the first support 51 that is farther from the spine 521 and is movable relative to the first support 51 with the relative movement of the first and second housings 12 and 14. With this structural arrangement, the first and second supports 51, 52 also maintain good support for the components of the flexible screen 20 that are being deployed from the housing assembly 10 as the flexible screen 20 expands or contracts with relative movement of the first and second housings 12, 14.
In the present embodiment, the sliding fit piece 53 may be plural, and in particular, as shown in fig. 7 to 9, the plural sliding fit pieces 53 are connected to the plural backbones 522. The slot wall of the slot 511 is provided with a limiting slot 512 extending along the first direction, and the sliding fit piece 53 is in sliding fit with the limiting slot 512, so that when the first support piece 51 and the second support piece 52 relatively move along the first direction, the sliding fit piece 53 slides along the limiting slot 512. In this embodiment, the sliding fit 53 is used to limit the skeleton 522 such that a gap is maintained between the skeleton 522 and at least one slot wall of the slot 511. Specifically, due to the cooperation of the sliding fit piece 53 and the limiting groove 512, a gap exists between the skeleton 522 and the groove wall of the slot 511, so that the contact surface between the skeleton 522 and the first support piece 51 is reduced, the contact friction force between the first support piece 51 and the second support piece 52 is reduced, the friction resistance between the first support piece 51 and the second support piece 52 is small, and the first support piece 51 and the second support piece 52 can smoothly move while supporting the flexible screen 20.
Further, the rigidity of the skeleton 522 is greater than that of the sliding fit 53, so that good supporting performance can be provided by the skeleton 522. It should be noted that, because the cooperation between the sliding fit piece 53 and the limiting groove 512 effectively reduces the contact friction between the skeleton 522 and the first support piece 51, the skeleton 522 may be made of a material with good supporting performance without considering the surface friction coefficient, for example, in some embodiments, the material of the first support piece 51 and the second support piece 52 may be a metal material.
It should be noted that, the friction coefficient between the sliding matching piece 53 and the limiting groove 512 is smaller than the friction coefficient between the skeleton 522 and the slot 511, so that when the contact surface between the skeleton 522 and the first supporting piece 51 is reduced by using the matching of the sliding matching piece 53 and the limiting groove 512, the friction resistance of the screen supporting assembly 50 can be reduced on the whole, so that the flexible telescopic movement of the screen supporting assembly 50 is convenient, and the smoothness of the telescopic movement of the flexible screen 20 is maintained while the flexible screen 20 is supported.
In some embodiments, the sliding fit piece 53 is made of polyoxymethylene, polyvinylidene fluoride or nylon 65, so that the sliding fit piece 53 has a self-lubricating property, and the smoothness of the relative movement of the first support piece 51 and the second support piece 52 is improved.
As shown in fig. 10 and 11, the sliding fitting 53 includes a main body 531 and a sliding fitting 532, wherein the main body 531 is connected to the frame 522, and the sliding fitting 532 protrudes from a side surface of the frame 522 and is slidably fitted in the limiting groove 512. In some embodiments, the skeleton 522 is provided with a hole 522a, as shown in fig. 13, at least a portion of the main body 531 is embedded in the hole 522a, so as to improve the connection stability between the sliding fitting 53 and the skeleton 522, so that the main body 531 is not easy to fall off from the skeleton 522 when the skeleton 522 moves in the slot 511 along the first direction.
As shown in fig. 12 and 13, in the second direction, a gap exists between the sliding fit portion 532 and the slot wall of the limit slot 512, and the gap between the sliding fit portion 532 and the slot wall of the limit slot 512 is smaller than the gap between the skeleton 522 and the slot wall of the slot 511, so that during the movement of the skeleton 522 along the slot 511, in the second direction, the sliding fit portion 532 is preferentially contacted with the slot wall of the limit slot 512, so that the skeleton 522 does not contact with the slot wall of the slot 511, thereby reducing the contact friction force between the skeleton 522 and the slot wall of the slot 511, enabling the movement of the skeleton 522 in the slot 511 to be smoother, improving the smoothness of the telescopic movement of the screen support assembly 50 along with the shell assembly 10 on the whole, and ensuring the smooth telescopic movement of the flexible screen 20 while providing good support for the flexible screen 20.
In some embodiments, a gap exists between the sliding fit portion 532 and the groove wall of the limit groove 512 along a third direction, and the gap between the sliding fit portion 532 and the groove wall of the limit groove 512 is smaller than the gap between the backbone 522 and the groove wall of the slot 511, wherein the third direction is perpendicular to the first direction and the second direction. With this structural arrangement, the sliding engagement portion 532 can be preferentially contacted with the groove wall of the limiting groove 512 in the third direction, so that a gap is maintained between the skeleton 522 and the groove wall of the slot 511, thereby reducing the contact friction between the skeleton 522 and the groove wall of the slot 511, and improving the smoothness of the telescopic movement of the screen support assembly 50 along with the shell assembly 10.
With continued reference to fig. 13, the first support member 51 has a first support surface 51a, the slot 511 extends through the first support surface 51a, and the frame 522 has a second support surface 52a, where the second support surface 52a and the first support surface 51a are used together to support the flexible screen 20. The second supporting surface 52a is flush with the first supporting surface 51a during the sliding process of the sliding fitting piece 53 along the limiting groove 512, so as to smoothly support the flexible screen 20.
The skeleton 522 may be in a gap with the side wall of the slot 511 or in a gap with the bottom wall of the slot 511. Specifically, as shown in fig. 13, the groove wall of the slot 511 adjacent to the first supporting surface 51a defines a side wall of the slot 511, and a gap exists between the skeleton 522 and the side wall of the slot 511. The groove wall of the slot 511 facing the first supporting surface 51a defines a bottom wall of the slot 511, and a gap exists between a side of the skeleton 522 facing away from the second supporting surface 52a and the bottom wall of the slot 511.
In other embodiments, the slot 511 may not extend through the first supporting surface 51a. Specifically, as shown in fig. 14, the first supporting member 51 has a supporting surface 51b, a back surface 51c and a side surface (not shown), the supporting surface 51b is used for supporting the flexible screen 20, the back surface 51c is opposite to the supporting surface 51b, the side surface is connected between the supporting surface 51b and the side surface 51c, the insertion slot 511 is located between the supporting surface 51b and the back surface 51c, an insertion slot is formed through the side surface, and the skeleton 522 is telescopically inserted from the insertion slot 511. With this configuration, the backbone 522 is mated with the socket 511 in a plug-in manner, and the support requirements for the flexible screen 20 can be satisfied. As can be appreciated, in this embodiment, the sliding fit between the skeleton 522 and the limiting groove 512 can also enable the skeleton 522 to keep a gap with at least one side wall of the slot 511, so as to reduce the contact friction between the skeleton 522 and the first support 51, and improve the smoothness of the telescopic movement of the flexible screen 20 supported by the screen support assembly 50.
As shown in connection with fig. 15, the slip fit 53 is disposed at an end of the frame 522 remote from the spine 521 such that the slip fit 53 provides a slip-aiding effect at the end of the frame 522.
In some embodiments, a locating pin 521a is attached to the spine 521 to be fixed relative to the second housing 14 by the locating pin 521 a. In other embodiments, the spine 521 may be snap-fit with the second housing 14 or the spine 521 may be attached to the second housing 14 with screws. The manner of connection between the spine 521 and the second housing 14 is not limited herein. By coupling the spine 521 with the second housing 14 such that the spine 521 is movable with the second housing 14 relative to the first support 51, as shown, for example, in connection with fig. 16 and 17, the second support 52 moves with the second housing 14 relative to the first support 51 as the second housing 14 moves.
