Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to electronic equipment. Background Technology

[0002] Roll-up electronic devices, due to their ability to change the display area, are now widely popular among users. Roll-up electronic devices typically use recycling mechanisms to recycle the flexible screen. However, current recycling mechanisms often experience arching issues with the recycling plate. Summary of the Invention

[0003] In view of this, this application provides an electronic device, including a first housing, a second housing, a flexible screen, and a recycling mechanism. The second housing is slidably connected to the first housing. The second housing is provided with a sliding groove, the extension direction of which is the same as the sliding direction of the second housing, and the bottom wall of the sliding groove is provided with a through hole. One end of the flexible screen is located on one side of the first housing and the second housing, and the other end extends from the end of the second housing away from the first housing to the other side of the second housing.

[0004] The recycling mechanism includes a recycling plate and a recycling belt. The recycling plate is fixed to the other end of the flexible screen. The recycling plate has a protrusion that passes through the through hole and is located in the sliding groove. A first limiting part is provided on the periphery of the protrusion, and the first limiting part abuts against the bottom wall of the sliding groove. One end of the recycling belt is fixed to the recycling plate, and the other end of the recycling belt passes through the second housing and is fixed to the first housing.

[0005] The electronic device provided in this application, through the cooperation of a recycling plate and a recycling belt, can recycle a flexible screen. Specifically, when the second housing slides towards the first housing, the recycling plate can use the recycling belt to recycle a portion of the flexible screen located on one side of the second housing to the other side. Furthermore, this application provides a sliding groove and a through hole on the second housing, while simultaneously providing a protrusion on the recycling plate, with a first limiting part on the periphery of the protrusion. This allows the first limiting part to abut against the bottom wall of the sliding groove. This abutment between the first limiting part and the bottom wall of the sliding groove prevents the recycling plate from arching away from the second housing, improving the flatness of the recycling plate. It also further prevents the recycling plate and the flexible screen from rubbing against the other housing components, thus avoiding damage to the various parts. Attached Figure Description

Detailed Implementation

[0028] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0029] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0030] With increasing user and market demand for larger display areas in mobile devices, the smartphone industry is experiencing a revolution in user experience driven by form factor innovation. For example, mobile phone displays have evolved from rigid screens to flexible screens, from small to large screens, and from static to dynamic mechanisms. Recently, major mobile phone manufacturers have been developing foldable screens, rollable screens, and sliding screens. This evolution in display form factors has also brought new challenges to the structural components of mobile phones that house these displays.

[0031] For example, a sliding electronic device has a display screen that can be stretched and shrunk to change its display area. An internal drive mechanism is mounted on a fixed housing and a sliding housing, causing the sliding housing to move relative to the fixed housing. The screen on the fixed housing side is fixed and cannot move, while the screen on the sliding housing side extends to the end of the sliding housing and then wraps around to the other side, placing the screen on the inner and outer sides of the sliding housing but not fixed. When the sliding component moves, the screen changes its display area accordingly.

[0032] When the electronic device moves from closed to open, the drive mechanism drives the sliding housing to slide away from the fixed housing, allowing a portion of the flexible screen on the other side of the sliding housing to move to one side, thereby increasing the display area of ​​the electronic device. When the electronic device moves from open to closed, the drive mechanism drives the sliding housing to slide closer to the fixed housing. At this time, the electronic device can use a recycling mechanism to move the portion of the flexible screen located on one side of the sliding housing back to the other side. However, due to the flexible screen itself or the recycling plate in the recycling mechanism, the recycling plate may arch away from the sliding housing, causing friction between the recycling plate and / or the flexible screen and other housings (such as the battery cover). This results in severe wear on the recycling plate, flexible screen, and battery cover, reducing performance and lifespan.

[0033] In view of this, and in order to solve the above problems, this application provides an electronic device. Please refer to the following: Figures 1-12 , Figure 1 This is a three-dimensional structural diagram of the recycling mechanism in one embodiment of this application.

[0034] This embodiment provides an electronic device 2, which includes a first housing 30, a second housing 40, a flexible screen 50, and a recycling mechanism 1. The second housing 40 is slidably connected to the first housing 30. The second housing 40 is provided with a sliding groove 41, the extension direction of which is the same as the sliding direction of the second housing 40, and the bottom wall 410 of the sliding groove 41 is provided with a through hole 42. One end of the flexible screen 50 is located on one side of the first housing 30 and the second housing 40, and the other end extends from the end of the second housing 40 away from the first housing 30 to the other side of the second housing 40. The recycling mechanism 1 includes a recycling plate 10 and a recycling belt 20. The recycling plate 10 is fixed to the other end of the flexible screen 50. The recycling plate 10 has a protrusion 11 that penetrates the through hole 42 and is located in the sliding groove 41. A first limiting part 12 is provided on the periphery of the protrusion 11, and the first limiting part 12 abuts against the bottom wall 410 of the sliding groove 41. One end of the recycling belt 20 is fixed to the recycling plate 10, and the other end of the recycling belt 20 passes through the second housing 40 and is fixed to the first housing 30.

[0035] The recycling agency 1 provided in this embodiment can be applied to a wide variety of electronic devices 2. Optionally, the electronic devices 2 provided in this embodiment include, but are not limited to, mobile terminals such as mobile phones, tablets, laptops, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers. This embodiment only uses a mobile phone as an example of electronic device 2 for illustration.

[0036] The electronic device 2 includes a first housing 30, a second housing 40, and a flexible screen 50. However, this does not mean that the electronic device 2 only includes the first housing 30, the second housing 40, and the flexible screen 50. It is just that the problem of arching can be solved by using the first housing 30, the second housing 40, the flexible screen 50, and the recycling mechanism 1 together.

[0037] The first housing 30 and the second housing 40 are partial housings of the electronic device 2, mainly used for mounting and protecting various structural components. The second housing 40 is slidably connected to the first housing 30; in other words, the second housing 40 can slide relative to the first housing 30. Alternatively, the first housing 30 can be understood as a fixed housing, and the second housing 40 as a sliding housing, with the two housings slidingly connected under the action of a driving mechanism. The specific structure of the driving mechanism is not limited in this embodiment. Of course, in other embodiments, the electronic device 2 may also include other housings, such as a third housing (not shown in the figure). The third housing and the second housing 40 may form a receiving space for accommodating the flexible screen 50, the recycling mechanism 1, and other structural components. In other words, the other end of the flexible screen 50 is located between the second housing 40 and the third housing.

[0038] Furthermore, the second housing 40 is provided with a sliding groove 41, and the extending direction of the sliding groove 41 is (e.g.) Figure 9 (as shown in the D direction) and the sliding direction of the second housing 40 (as shown in the D direction) Figure 3 In the D1 direction and Figure 7 As shown in the D direction, the length direction of the sliding groove 41 is the same as the sliding direction of the second housing 40, ensuring that the structural components located in the sliding groove 41 can also move in coordination when the second housing 40 slides, preventing interference and other problems. In addition, a through hole 42 that can connect to the receiving space is also provided on the bottom wall 410 of the sliding groove 41, which facilitates the subsequent entry of structural components from the receiving space into the sliding groove 41.

[0039] The flexible screen 50 is the main component in the electronic device 2 that performs the display function. One end of it is fixed to one side of the first housing 30 and the second housing 40, and the other end extends from the end of the second housing 40 away from the first housing 30 to the other side of the second housing 40. In other words, the flexible screen 50 is located on both the inner and outer sides of the first housing 30 and the second housing 40, and it is precisely by utilizing the above arrangement that the subsequent sliding function can be realized. Optionally, the other end of the flexible screen 50 can be located between the second housing 40 and the third housing, that is, within the receiving space.

[0040] The recycling mechanism 1 in this embodiment mainly includes a recycling plate 10 and a recycling belt 20. The recycling plate 10 primarily provides a mounting mechanism for the recycling belt 20, acting as a bridge between the recycling belt 20 and the flexible screen 50. The recycling plate 10 is fixed to the other end of the flexible screen 50, i.e., the recycling plate 10 is fixed to the end of the flexible screen 50 located within the receiving space. One end of the recycling belt 20 is fixed to the recycling plate 10, and the other end passes through the second housing 40 and is fixed to the first housing 30. This structure enables the recycling function of the flexible screen 50. Specifically, during the process of the electronic device 2 moving from closed to open, the second housing 40 slides away from the first housing 30, causing the flexible screen 50 to be constrained by the end of the second housing 40 away from the first housing 30. This causes the flexible screen 50 located on the other side of the second housing 40 to move to one side of the second housing 40, thereby increasing the display area of ​​the electronic device 2. At this time, the other end of the flexible screen 50 moves outward via the recycling plate 10 and the recycling belt 20. As the electronic device 2 moves from unfolding to closing, the second housing 40 slides towards the first housing 30. This can also be understood as the second housing 40 remaining stationary while the first housing 30 slides towards the second housing 40. In this case, the first housing 30 can drive the other end of the recycling belt 20 to move along with it, thereby causing one end of the recycling belt 20 to pull the other end of the flexible screen 50 towards the first housing 30 via the recycling plate 10. This allows the portion of the flexible screen 50 located on one side of the second housing 40 to move back to the other side of the second housing 40, reducing the display area of ​​the electronic device 2.

[0041] Additionally, the recycling plate 10 is provided with a protrusion 11, which penetrates the through hole 42 and is located within the sliding groove 41. Simultaneously, a first limiting part 12 is provided on the periphery of the protrusion 11, which abuts against the bottom wall 410 of the sliding groove 41. This abutting engagement between the first limiting part 12 and the bottom wall 410 of the sliding groove 41 prevents the recycling plate 10 from arching away from the second housing 40, i.e., prevents the recycling plate 10 and the flexible screen 50 from moving closer to the third housing, and prevents contact between the recycling plate 10 and the flexible screen 50 and the third housing, thus preventing wear or even damage. In other words, this embodiment, through the engagement of the first limiting part 12 and the bottom wall 410 of the sliding groove 41, restricts the movement of the recycling plate 10 in the thickness direction of the electronic device 2, i.e., restricts the movement in the Z-direction (e.g., ...). Figure 12 The movement (as shown) prevents the back of the flexible screen 50 from arching.

[0042] Optionally, this embodiment is illustrated by having two recycling belts 20 on a recycling plate 10, with the two recycling belts 20 spaced apart along the length of the recycling plate 10.

[0043] Please refer to this again. Figures 11-12In this embodiment, the first limiting part 12 is rotatably connected to the protrusion 11, and the movement of the recycling plate 10 can drive the first limiting part 12 to slide and rotate relative to the bottom wall 410 of the sliding groove 41.

[0044] Based on the provision of the first limiting part 12, this embodiment also allows the first limiting part 12 to be rotatably connected to the protrusion 11. In other words, the first limiting part 12 can rotate, that is, the first limiting part 12 can rotate relative to the protrusion 11. As can be seen from the above, during the movement of the electronic device 2, that is, during the process of the electronic device 2 from closing to unfolding or from unfolding to closing, the retrieval plate 10 will also slide relative to the second housing 40 during the movement of the second housing 40, thereby realizing the winding or unwinding of the flexible screen 50. Therefore, the protrusion 11 provided on the retrieval plate 10 and the first limiting part 12 provided around the protrusion 11 will also slide within the sliding groove 41. In this embodiment, the first limiting part 12 is rotatably connected to the protrusion 11, so that when the retrieval plate 10 moves, the first limiting part 12 can not only slide with the bottom wall 410 of the sliding groove 41, but also rotate with the bottom wall 410 of the sliding groove 41. This converts the sliding friction between the first limiting part 12 and the bottom wall 410 of the sliding groove 41 during the movement of the recycling plate 10 into rolling friction, thereby reducing the friction between the first limiting part 12 and the bottom wall 410 of the sliding groove 41. Furthermore, the rotation direction of the first limiting part 12 at this time can be understood as perpendicular to the contact surface of the bottom wall 410. The contact surface of the bottom wall 410 refers to the surface of the bottom wall 410 that contacts the first limiting part 12.

[0045] Of course, in other embodiments, the first limiting part 12 may also be fixed on the periphery of the protrusion 11, that is, the first limiting part 12 and the protrusion 11 remain relatively stationary, and the first limiting part 12 will not rotate relative to the protrusion 11, but this can also make the recycling plate 10 slide relative to the second housing 40.

[0046] Please refer to this as well. Figures 1-2 , Figure 11 ,and Figure 13 . Figure 13 for Figure 11 The diagram shows a cross-sectional view of the recycling mechanism and the second housing portion in another embodiment. In this embodiment, the recycling plate 10 is provided with a second limiting part 13 that penetrates the through hole 42 and is located within the sliding groove 41. The second limiting part 13 abuts against the side wall 411 of the sliding groove 41.

[0047] Based on the first limiting part 12, this embodiment may further add a second limiting part 13. The second limiting part 13 may be provided on the recovery plate 10 and pass through the through hole 42 located in the sliding groove 41, and the second limiting part 13 abuts against the side wall 411 of the sliding groove 41. By utilizing the mutual cooperation between the second limiting part 13 and the side wall 411 of the sliding groove 41, the second limiting part 13 abuts against the side wall 411 of the sliding groove 41, thereby limiting the displacement of the recovery plate 10 in the direction perpendicular to the sliding direction, that is, limiting the Y-direction of the recovery plate 10 (e.g., Figure 13 The displacement shown further restricts the arching of the recovery plate 10 and reduces the amount of arching deformation in the middle of the recovery plate 10.

[0048] In other words, the second limiting part 13 abuts against the side wall 411 of the sliding groove 41. When the recovery plate 10 wants to arch, the second limiting part 13 will tightly abut against the side wall 411, and the side wall 411 will give the recovery plate 10 a reverse pulling force (such as...). Figure 13 As shown in F1, this tension will cause the recovery to tend to flatten, which can also reduce the arching problem of the recovery plate 10.

[0049] Please refer to this as well. Figure 11 and Figure 14 , Figure 14 for Figure 11 The diagram shows a partial cross-sectional view of the recycling mechanism and the second housing in another embodiment. In this embodiment, the sidewall 411 includes a first sub-sidewall 411a and a second sub-sidewall 411b disposed opposite to each other. The first sub-sidewall 411a is closer to the center of the second housing 40 than the second sub-sidewall 411b. The second limiting portion 13 abuts against the first sub-sidewall 411a.

[0050] Because the sliding groove 41 has a first sub-sidewall 411a and a second sub-sidewall 411b that are arranged opposite to each other, and the first sub-sidewall 411a is closer to the center of the second housing 40 than the second sub-sidewall 411b (e.g. Figure 11 As shown in Figure O, the first sub-sidewall 411a is further inward, and the second sub-sidewall 411b is further outward. In this embodiment, the second limiting part 13 abuts against the first sub-sidewall 411a. In this way, if the recycling plate 10 is to arch, the second limiting part 13 can immediately and tightly abut against the sidewall 411a to limit the recycling plate 10, thereby further improving the limiting effect and preventing the recycling plate 10 from arching.

[0051] Please refer to this again. Figure 11 , Figures 13-14 In this embodiment, the second limiting part 13 is rotatably connected to the recycling plate 10, and the movement of the recycling plate 10 can drive the second limiting part 13 to slide and rotate relative to the side wall 411 of the sliding groove 41.

[0052] Based on the addition of the second limiting part 13, this embodiment also allows the second limiting part 13 to be rotatably connected to the recycling plate 10. In other words, the second limiting part 13 can rotate, that is, the second limiting part 13 can rotate relative to the recycling plate 10. As can be seen from the above, during the movement of the electronic device 2, that is, during the process of the electronic device 2 from closing to unfolding or from unfolding to closing, the recycling plate 10 will also slide relative to the second housing 40 during the movement of the second housing 40, thereby realizing the winding or unwinding of the flexible screen 50. Therefore, the second limiting part 13 provided on the recycling plate 10 will also slide within the sliding groove 41. In this embodiment, the second limiting part 13 is rotatably connected to the recycling plate 10, so that when the recycling plate 10 moves, the second limiting part 13 can not only slide with the side wall 411 of the sliding groove 41, but also rotate with the side wall 411 of the sliding groove 41. The sliding friction between the second limiting part 13 and the side wall 411 of the sliding groove 41 is converted into rolling friction when the recycling plate 10 moves, thereby reducing the friction between the second limiting part 13 and the side wall 411 of the sliding groove 41. Furthermore, the rotation direction of the second limiting part 13 at this time can be understood as parallel to the contact surface of the bottom wall 410, or perpendicular to the lower surface of the side wall 411. The contact surface of the side wall 411 refers to the surface of the side wall 411 that contacts the second limiting part 13.

[0053] Of course, in other embodiments, the second limiting part 13 may also be fixed on the recycling plate 10, that is, the second limiting part 13 and the recycling plate 10 remain relatively stationary, and the second limiting part 13 will not rotate relative to the recycling plate 10, but this can still allow the recycling plate 10 to slide relative to the second housing 40.

[0054] Please refer to this as well. Figure 6 , Figure 10 ,and Figure 15 , Figure 15 This is a three-dimensional structural diagram of the recycling mechanism according to another embodiment of this application. In this embodiment, the recycling mechanism 1 further includes a mounting member 60 and an elastic member 70. The mounting member 60 is fixed to the first housing 30, and the other end of the recycling belt 20 is fixed to the mounting member 60. One end of the elastic member 70 is connected to the mounting member 60, and the other end of the elastic member 70 is connected to the first housing 30. The elastic member 70 is in an elastic deformation state and can provide a tension force to the other end of the recycling belt 20 away from the first housing 30 through the mounting member 60.

[0055] In addition to the aforementioned recycling plate 10 and recycling belt 20, the recycling mechanism 1 may also include a mounting member 60 and an elastic member 70. The mounting member 60 is fixed to the first housing 30, and the other end of the recycling belt 20 is fixed to the mounting member 60. Therefore, in this embodiment, the other end of the recycling belt 20 being fixed to the first housing 30 is achieved through the mounting member 60. One end of the elastic member 70 can be connected to the mounting member 60, and the other end of the elastic member 70 can be connected to the first housing 30. Optionally, the connection between the elastic member 70 and the mounting member 60 and the first housing 30 can be a fixed connection or an abutment.

[0056] Furthermore, the elastic element 70 is in an elastic deformation state, which can be either a compression state or a tension state. The elastic element 70 in the elastic deformation state can, through the mounting member 60, apply a tension force (e.g., ...) to the other end of the recovery belt 20 in a direction away from the first housing 30. Figure 6 and Figure 10 (As shown in F2). In other words, the elastic element 70 provides the recovery belt 20 in the X direction (e.g., ...). Figure 6 and Figure 10 The tension force (as shown) also tightens the recovery plate 10 in the X direction through the recovery belt 20, further reducing the arching deformation of the recovery plate 10.

[0057] Please refer to Figure 16 , Figure 16 This is an exploded view of the mounting component according to one embodiment of this application. In this embodiment, the mounting component 60 includes a mounting part 61 and a sliding part 62. The mounting part 61 is fixed to the first housing 30 and has an accommodating space 63. The sliding part 62 is disposed within the accommodating space 63. The sliding part 62 and the mounting part 61 are connected by a sliding groove 64 and a slider 65. The sliding groove 64 is disposed in one of the sliding part 62 and the mounting part 61, and the slider 65 is disposed in the other of the sliding part 62 and the mounting part 61. One end of the elastic member 70 is connected to the sliding part 62.

[0058] The mounting component 60 may include a mounting portion 61 and a sliding portion 62. The mounting portion 61 is fixed to the first housing 30 and has a receiving space 63. The sliding portion 62 is disposed within the receiving space 63 and is slidable relative to the mounting portion 61. The sliding of the sliding portion 62 and the mounting portion 61 can be connected by a sliding groove 64 and a slider 65. The sliding groove 64 is disposed in one of the sliding portion 62 and the mounting portion 61, and the slider 65 is disposed in the other. When the sliding groove 64 is disposed in the sliding portion 62, the slider 65 is disposed in the mounting portion 61, and vice versa. This embodiment is only illustrated with the sliding groove 64 disposed in the mounting portion 61 and the slider 65 disposed in the sliding portion 62.

[0059] In addition, when the slider 65 is disposed on the sliding part 62 and the slide groove 64 is disposed on the mounting part 61, the mounting part 61 is also provided with an assembly hole 67 communicating with the slide groove 64, and the slider 65 can be disposed in the slide groove 64 through the assembly hole 67.

[0060] Optionally, the sliding part 62 may also be provided with a protrusion 66, which is connected to the first housing 30. The elastic member 70 is sleeved on the protrusion 66, with one end of the elastic member 70 abutting against the sliding part 62 and the other end of the elastic member 70 abutting against the first housing 30.

[0061] Please refer to this as well. Figure 6 , Figures 10-11 ,and Figure 17 , Figure 17 This is a three-dimensional structural diagram of the recycling mechanism in another embodiment of this application. In this embodiment, the second housing 40 is provided with a mounting hole 43, and the recycling mechanism 1 further includes a rotating member 80, which is mounted on the side wall of the mounting hole 43. The recycling belt 20 is wound around the rotating member 80 and passes through the second housing 40 through the mounting hole 43.

[0062] In addition to the recycling plate 10 and the recycling belt 20, the recycling mechanism 1 may also include a rotating member 80, and the second housing 40 is provided with a mounting hole 43. Optionally, the mounting hole 43 and the sliding groove 41 on the second housing 40 are arranged in a direction parallel to the sliding direction of the second housing 40. The rotating member 80 can be mounted on the side wall of the mounting hole 43 so that the rotating member 80 can rotate relative to the second housing 40. The recycling belt 20 can be wound around the rotating member 80 and pass through the second housing 40 through the aforementioned mounting hole 43, thereby facilitating the passage of the recycling belt 20 through the second housing 40. The rotation between the recycling belt 20 and the rotating member 80 can also reduce the friction of the recycling belt 20, improving the smoothness of the movement of the recycling mechanism 1.

[0063] Please refer to this as well. Figures 18-19 , Figure 18 This is a partial cross-sectional schematic diagram of the recovery structure and the second shell in another embodiment of this application. Figure 19 This is a schematic diagram showing the forces acting on the recycling plate and the second limiting part in one embodiment of this application. In this embodiment, the recycling mechanism 1 includes two recycling belts 20, which are arranged at intervals along a sliding direction perpendicular to the second housing 40. The recycling plate 10 is provided with two second limiting parts 13, and the second housing 40 is provided with two sliding grooves 41. Each second limiting part 13 abuts against the side wall 411 of one sliding groove 41 near the other sliding groove 41.

[0064] Two recycling belts 20 can be provided in the electronic device 2, and the two recycling belts 20 are arranged at intervals along a sliding direction perpendicular to the second housing 40. As can be seen from the above, two second limiting parts 13 can be provided on the recycling plate 10, and each second limiting part 13 abuts against the side wall 411 of a sliding groove 41. In this embodiment, each second limiting part 13 abuts against the side wall 411 of one sliding groove 41 that is close to the other sliding groove 41. In other words, the two second limiting parts 13 abut against the side walls 411 of the two sliding grooves 41 that are close to each other, so that the two side walls 411 will exert two pulling forces (e.g., ...) in opposite directions on the two second limiting parts 13. Figure 19 As shown in F1), this further solves the arching problem of the recycling plate 10, so that the arched area in the middle of the recycling plate 10 will be subjected to a flattening force (such as...). Figure 19 As shown in F3, this makes the recycling plate 10 tend to flatten.
