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, a flexible screen 20, and a screen recovery structure 30.

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.

The housing assembly 10 includes a first housing 12 and a second housing 14, the first housing 12 and the second housing 14 being relatively movable in a first direction. Specifically, in the present embodiment, the first housing 12 is slidably connected to the second housing 14. In other words, the first housing 12 is capable of sliding relative to the second housing 14. 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.

As shown in connection with fig. 3 and 4, flexible screen 20 is coupled to first housing 12 and 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. Understandably, the flexible screen 20 is a telescoping motion along a first direction due to the relative motion of the first housing 12 and the second housing 14 in the first direction.

Further, the first housing 12 is slidable in a first direction relative to the second housing 14 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 first housing 12 is in the folded position, and is convenient to carry. As shown in fig. 3 and 4, when the first housing 12 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 junction component 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 when a maximum display screen is displayed, 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 retracted position, the extended position, and the like refer to the relative positions of the first housing 12 and the second housing 14. For simplicity, the similar expressions "the first housing 12 is in the folded position" or "in the folded position" refer to the first housing 12 being in the folded position relative to the second housing 14, and the similar expressions "the first housing 12 is in the unfolded position" or "in the unfolded position" refer to the first housing 12 being in the unfolded position relative to the second housing 14.

As shown in connection with fig. 2 and 4, flexible screen 20 may include a fixed end 202 and a free end 204 disposed opposite each other, where fixed end 202 is disposed on first housing 12 and is fixed relative to the position of first housing 12. When the first housing 12 is in the collapsed position, the free end 204 of the flexible screen 20 is received within the housing assembly 10 such that a portion of the structure of the flexible screen 20 is hidden from the housing assembly 10 and a portion of the flexible screen 20 hidden within the housing 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 flexible screen 20 to be deployed within the second housing 14 or into 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 end 202 and the first housing 12 as examples, the positions of the fixing end 202 and the first housing 12 are relatively fixed, which may be that the fixing end 202 is in direct contact with the first housing 12, for example, a threaded fastener or a clamping manner is adopted to realize the direct fixation of the fixing end 202 and the first housing 12, or that the fixing end 202 is indirectly fixed with the first housing 12 through a structure such as an adhesive layer, an intermediate connecting plate, and the like.

In some embodiments, when the first housing 12 is in the folded position, the portion of the flexible screen 20 exposed outside the housing assembly 10 is generally rectangular, and may have a size of 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.

The screen retracting structure 30 serves to guide and tension the flexible screen 20 during the extension and retraction of the flexible screen 20, so that the flexible screen 20 smoothly extends and contracts. Understandably, the screen recovery structure 30 is disposed within the housing cavity 10a of the case assembly 10.

Specifically, as shown in connection with fig. 5 to 7, the screen recycling structure 30 includes a guide 31, a recycling member 32, a first rolling assembly 33, and a second rolling assembly 34. The guide 31 is provided with a first groove 311 and a second groove 312, the first groove 311 and the second groove 312 being parallel to each other. The retrieving member 32 is used to connect with the free end 204 of the flexible screen 20, and when the flexible screen 20 moves telescopically, the retrieving member 32 moves relative to the guiding member 31 to guide the free end 204 of the flexible screen 20 to move relative to the guiding member 31. In this embodiment, the first rolling member 33 is connected to the retrieving member 32, and the first rolling member 33 is in rolling contact with the sidewall of the first recess 311 when the flexible screen 20 is moved in a telescopic manner. The second rolling assembly 34 is connected to the retrieving member 32, and the second rolling assembly 34 is in rolling contact with the sidewall of the second recess 312 when the flexible screen 20 is moved telescopically.

After the screen recycling structure 30 is assembled to the electronic device 100, the first recess 311 and the second recess 312 each extend in the direction of the telescopic movement of the flexible screen 20 (i.e., the first direction). In the flexible screen 20 telescopic movement process, the recovery piece 32 moves along the first direction relative to the guide piece 31, the first rolling component 33 and the second rolling component 34 are in rolling contact with the side walls of the first groove 311 and the second groove 312 respectively, movement flexibility of the recovery piece 32 is improved, and traction of the recovery piece 32 to the free end 204 of the flexible screen 20 is utilized, so that the flexible screen 20 is not easy to skew and friction with surrounding parts is generated, smoothness of the flexible screen 20 telescopic movement is effectively improved, and probability of blocking in the flexible screen 20 telescopic movement process is reduced.

The guide member 31 may be fixed relative to the first housing 12 or fixed relative to the second housing 14, so long as the free end 204 of the flexible screen 20 stably moves along the first groove 311 and the second groove 312 of the guide member 31 through the recovery member 32 during the telescopic movement of the flexible screen 20 when the first housing 12 moves relative to the second housing 14.

The guide 31 may be integrally formed with the first housing 12 or the second housing 14, or may be connected by a structure such as a buckle, glue, or screw.

The screen recycling structure 30 is a mirror-symmetrical structure, that is, the screen recycling structure 30 is symmetrically disposed with a certain plane as a mirror plane. For example, as shown in fig. 6, the first groove 311 and the second groove 312 on the guide 31 are symmetrically disposed about the mirror surface S0, and accordingly, the first rolling assembly 33 and the second rolling assembly 34 connected to the recovery member 32 are symmetrically disposed about the mirror surface S0.

Referring to fig. 8, the first rolling assembly 33 includes a base 331, a first roller 332 and a second roller 333, the base 331 is rotationally connected to the recovering member 32, the base 331 is connected to a first pin 3321 and a second pin 3331, the first roller 332 and the second roller 333 are rotationally connected to the base 331, and the first roller 332 and the second roller 333 are spaced from each other. Because the base 331 is rotatably connected with the recovering member 32, the first rolling assembly 33 moves along the first groove 311 and the second rolling assembly 34 moves along the second groove 312 during the moving process of the recovering member 32 relative to the guiding member 31, even if the recovering member 32 slightly deflects relative to the movable seat, the base 331 can rotate relative to the recovering member 32, so that the first roller 332 and the second roller 333 on the base 331 can maintain rolling contact with the corresponding side walls of the first groove 311 or the second groove 312, so that the recovering member 32 smoothly moves relative to the guiding member 31, friction between the free end 204 of the flexible screen 20 and surrounding parts is reduced, and smoothness of the flexible screen 20 during telescopic movement is improved.

It should be noted that the structure of the second rolling assembly 34 may be the same as that of the first rolling assembly 33, and will not be described herein.

As shown in fig. 8 and 9, the first roller 332 is rotatably connected to the base 331 through a first pin 3321, and the recovery member 32 is provided with a first space-avoiding groove 32a, and at least a part of the structure of the first pin 3321 is accommodated in the first space-avoiding groove 32a, so that the thickness of the structural member is reduced as much as possible in the thickness direction of the electronic device 100, and the thickness of the electronic device 100 is reduced. As shown in fig. 10 and 11, the first clearance groove 32a provides a clearance space for the first roller 332, so as to limit the movement range of the first roller 332 along with the movement of the base 331, specifically, during the rotation of the base 331 relative to the recovery member 32, when the first rolling along with the base 331 moves to contact with the groove wall of the first clearance groove 32a, the first clearance groove 32a limits the first roller 332, so that the rotation range of the base 331 relative to the recovery member 32, that is, the deflection range of the base 331 relative to the recovery member 32 is limited.

The diameter of the shaft hole of the first roller 332 is larger than that of the first pin 3321, so that the first roller 332 can rotate around the first pin 3321 after being sleeved with the first pin 3321. In this embodiment, the first pin 3321 may be fixed to the base 331 by welding, injection molding, plugging, or the like. In some embodiments, the first pin 3321 may be rotatably disposed on the base 331, such that the first roller 332 can rotate relative to the base 331 even if the first roller 332 is fixed to the first pin 3321. The rotational connection between the first pin 3321 and the base 331 is not limited herein.

In some embodiments, the second roller 333 is rotatably connected to the base 331 through a second pin 3331, and the recycling member 32 is provided with a second space-avoiding groove 32b, at least a portion of the second pin 3331 is received in the second space-avoiding groove 32b, so as to reduce the thickness of the structural member in the thickness direction of the electronic device 100 as much as possible, and facilitate the light and thin of the electronic device 100. In addition, the second clearance groove 32b provides clearance space for the second roller 333, so as to limit the movement stroke of the second roller 333 along with the base 331, specifically, when the second roll moves along with the base 331 to contact with the groove wall of the second clearance groove 32b, the second clearance groove 32b limits the second roller 333, so that the rotation amplitude of the base 331 relative to the recovery member 32, that is, the deflection stroke of the base 331 relative to the recovery member 32 is limited. The connection between the second pin 3331 and the base 331 and the rotational connection of the second roller 333 with respect to the base 331 can refer to the aforementioned connection between the first pin 3321 and the first roller 332 and the base 331, and will not be described herein.

It should be noted that, in some embodiments, the recycling member 32 is provided with a clearance space for providing a movement space for the first roller 332 or the second roller 333. Specifically, the recovery member 32 is provided with a first space avoiding groove 32a, at least a portion of the first roller 332 is configured to be received in the first space avoiding groove 32a, which is not only beneficial to realizing the light and thin of the electronic device 100, but also limits the rotation range of the base 331 relative to the recovery member 32 by using the first space avoiding groove 32a to limit the first roller 332.

In some embodiments, the recycling member 32 is provided with the second space avoiding groove 32b, and at least a portion of the second roller 333 is accommodated in the second space avoiding groove 32b, which is not only beneficial to realizing the light and thin of the electronic device 100, but also restrains the rotation range of the base 331 relative to the recycling member 32 by limiting the second roller 333 by the second space avoiding groove 32 b.

It should be noted that, in the embodiment in which the first rolling assembly 33 and the second rolling assembly 34 each include the base 331, the first roller 332, and the second roller 333, the recovery member 32 connected to the free end 204 of the flexible screen 20 moves relative to the guide member 31 along with the telescopic movement of the flexible screen 20, and the rollers (e.g., the first roller 332 and the second roller 333) in the first rolling assembly 33 and the second rolling assembly 34 maintain the parallel arrangement direction of the rollers located in the first groove 311 and the parallel arrangement direction of the rollers located in the second groove 312 while maintaining rolling contact with the sidewalls of the corresponding grooves (e.g., the first groove 311 and the second groove 312), so as to facilitate the movement stability of the free end 204 of the flexible screen 20, reduce the probability of the free end 204 of the flexible screen 20 being deflected, and improve the smoothness of the telescopic movement of the flexible screen 20.

As shown in fig. 5, 12 and 13, the seat 331 and the recovery member 32 can be rotatably connected by a limiting pin 334. Specifically, the stopper pin 334 has a shaft body 3341 and a blocking wall 3342, the blocking wall 3342 is connected to the circumferential side of the shaft body 3341, and the blocking wall 3342 is located between the recovery member 32 and the seat body 331 to keep the seat body 331 and the recovery member 32 spaced apart. The blocking wall 3342 may be an annular protrusion formed around the shaft 3341, or may be a protrusion connected to the circumferential side of the shaft 3341, and the structure of the blocking wall 3342 is not limited herein, so long as the seat 331 and the recovery member 32 can be separated from each other, and the seat 331 can smoothly rotate relative to the recovery member 32 without interference.

Further, a limiting groove 32c is disposed on a side of the recovery member 32 opposite to the base 331, a limiting piece 335 is disposed in the limiting groove 32c, and one end of the shaft 3341 is disposed through the recovery member 32 and connected to the limiting piece 335, so that the recovery member 32 is clamped between the limiting piece 335 and the blocking wall 3342, and the base 331 is rotatably connected to the shaft 3341 and is limited to the shaft 3341 along the axial direction of the shaft 3341. In this embodiment, by using the cooperation between the limiting plate 335 and the limiting slot 32c, the limiting plate 335 is limited in the limiting slot 32c without deflection, so that the shaft body 3341 connected with the limiting plate 335 cannot rotate relative to the recovery member 32, and when the seat body 331 rotates around the shaft body 3341, the shaft body 3341 cannot be loosened, thereby improving the structural stability.

The shape of the limiting plate 335 may be rectangular, triangular, or any other shape, such as pentagonal or hexagonal. The shape of the stopper 335 is not limited, and the shaft 3341 and the recovery member 32 may be stably connected by the stopper 335 and the blocking wall 3342.

As shown in fig. 8 and 13, the shaft body 3341 is sleeved with a collar 336, and the seat body 331 is limited between the blocking wall 3342 and the collar 336 along the axial direction of the shaft body 3341, so that the seat body 331 cannot fall off from the shaft body 3341, and the rotation stability of the seat body 331 around the shaft body 3341 is facilitated.

The shaft body 3341 and the limiting piece 335 can be fixed by welding or by glue bonding. The shaft body 3341 and the collar 336 may be fixed by welding or by glue bonding. The connection between the shaft body 3341 and the stopper 335 and collar 336 is not limited herein.

It should be noted that, in some embodiments, the shaft 3341 may be rotatably connected to the recovering member 32, so that the base 331 may also rotate relative to the recovering member 32 through the shaft 3341. The rotational connection structure between the base 331 and the recovering member 32 is not limited herein, as long as the base 331 can rotate relative to the recovering member 32, so that the first roller 332 and the second roller 333 on the base 331 keep rolling contact with the side walls of the grooves (e.g. the first groove 311 and the second groove 312).

In some embodiments, screen recovery structure 30 includes a flexible strap (not shown) coupled to recovery 32 for applying tension to free end 204 of flexible screen 20 via recovery 32, thereby maintaining flexible screen 20 in a relaxed state without wrinkling to facilitate a flat display of the portion of flexible screen 20 exposed to housing assembly 10. The number of the flexible bands may be 2 or more, and is not limited herein.

The screen recovery structure 30 is further described below in conjunction with fig. 5, 12 and 13. As shown in fig. 5, the recovery member 32 has a first fixing portion 321 and a second fixing portion 322 that are disposed at intervals, the first fixing portion 321 is connected with a first flexible band, the second fixing portion 322 is connected with a second flexible band, and during the expansion and contraction of the flexible screen 20, the first flexible band and the second flexible band both apply tension to the free end 204 of the flexible screen 20 by pulling the recovery member 32.

The recovery member 32 has a third fixing portion 323, and the third fixing portion 323 is adapted to be connected to the free end 204 of the flexible screen 20. The recovery member 32 may be glued to the free end 204 of the flexible screen 20 or may be connected by a snap-fit arrangement. For example, in some embodiments, the third fixing portion 323 of the recovery member 32 is a sheet material capable of being rolled up, and when the free end 204 of the flexible screen 20 is stacked on the third fixing portion 323, the third fixing portion 323 can stably connect the flexible screen 20 to the recovery member 32 in a rolled up manner.

In some embodiments, since the first fixing portion 321 and the second fixing portion 322 are disposed at intervals, the first flexible strap and the second flexible strap connected with the first fixing portion 321 and the second fixing portion 322 have different points of application to the recovery member 32, so that when the first flexible strap and the second flexible strap pull the flexible screen 20 through the recovery member 32, the first flexible strap and the second flexible strap and the flexible screen 20 generate uneven traction force to the recovery member 32, so that the recovery member 32 deforms, and when the recovery member 32 deforms, the first rolling assembly 33 and the second rolling assembly 34 are tightened or opened. Here, the first rolling element 33 and the second rolling element 34 of the recovering element 32 are the first rolling element 33 and the second rolling element 34 which are close to each other when the recovering element 32 is deformed, and the first rolling element 33 and the second rolling element 34 are the first rolling element 33 and the second rolling element 34 which are far away from each other when the recovering element 32 is deformed.

As shown in fig. 12 and 13, when the recovery member 32 tightens the first rolling member 33 and the second rolling member 34, the first rolling member 33 and the second rolling member 34 roll in contact with the side walls of the first groove 311 and the second groove 312, which are closer to the middle of the recovery member 32, respectively, due to the first rolling member 33 and the second rolling member 34 being close to each other. In this way, the rolling contact between the first rolling assembly 33 and the second rolling assembly 34 and the guide member 31 can be utilized to improve the moving stability and smoothness of the recovery member 32 relative to the guide member 31, so that the free end 204 of the flexible screen 20 can move smoothly relative to the guide member 31 under the traction of the recovery member 32, the friction probability between the free end 204 of the flexible screen 20 and surrounding parts is reduced, and the jamming phenomenon is reduced.

When the recovery piece 32 opens the first rolling component 33 and the second rolling component 34, the first rolling component 33 and the second rolling component 34 are far away from each other, and the first rolling component 33 and the second rolling component 34 are respectively in rolling contact with the side walls of the first groove 311 and the second groove 312 far away from the middle of the recovery piece 32, so that the rolling contact between the first rolling component 33 and the second rolling component 34 and the guide piece 31 improves the moving stability and smoothness of the recovery piece 32 relative to the guide piece 31, and the free end 204 of the flexible screen 20 stably moves relative to the guide piece 31 under the traction of the recovery piece 32, thereby reducing the friction probability of the free end 204 of the flexible screen 20 and surrounding parts and reducing the clamping stagnation phenomenon.
