Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0025] See also Figures 1 to 3 , Figure 1 is a schematic diagram of the three-dimensional structure of a screen flipping device 100 according to an embodiment of an implementation mode of the present invention; Figure 2 yes Figure 1 A schematic diagram of a three-dimensional structure of the screen flipping device 100 at another viewing angle; Figure 3 yes Figure 1 The screen flipping device 100 is a three-dimensional structural schematic diagram in a cross-sectional state. The embodiment of the present invention provides a screen flipping device 100, which includes a fixed plate 10, a mounting member 20, a push-pull mechanism 30 and a connecting rod structure 40. The mounting member 20 is rotatably connected to the fixed plate 10, and the mounting member 20 is used to install a display screen (not shown). The push-pull mechanism 30 is installed on the side of the fixed plate 10 that is away from the mounting member 20. The push-pull mechanism 30 includes a driving assembly 31 and a driving block 32, and the driving assembly 31 is connected to the driving block 32 and can drive the driving block 32 to move linearly. The connecting rod structure 40 is fixedly connected to the mounting member 20. One of the connecting rod structure 40 and the driving block 32 is provided with a connecting rod 321, and the other of the connecting rod structure 40 and the driving block 32 is provided with a sliding groove 401, and the connecting rod 321 extends into the sliding groove 401. When the driving block 32 moves in a straight line, the connecting rod 321 abuts against the groove wall of the sliding groove 401 and slides along the groove wall, so that the connecting rod structure 40 drives the mounting member 20 to flip relative to the fixing plate 10 .

[0026] Specifically, the fixed plate 10 can be a part of the appearance of the electronic device, such as a decorative plate. The mounting member 20 is provided with an assembly groove 201 on the side facing away from the fixed plate 10, and the assembly groove 201 is used to install the display screen. The driving component 31 can provide a driving force to the driving block 32 through driving devices such as an electric cylinder, a pneumatic cylinder, a hydraulic cylinder and a motor, so that the driving block 32 can reciprocate in a straight line. It can be understood that the driving component 31 can apply two driving forces in opposite directions to the driving block 32, so that the driving block 32 can drive the fixed plate 10 to flip relative to the fixed plate 10 to close or unfold through the connecting rod structure 40.

[0027] In this embodiment, the connecting rod structure 40 and the mounting member 20 are separate structures, and the connecting rod structure 40 is fixed to the mounting member 20 by screws. In other embodiments, the connecting rod structure 40 and the mounting member 20 can also be an integrated structure, for example, the connecting rod structure 40 and the mounting member 20 are two parts of the same plate.

[0028] In this embodiment, the connecting rod 321 is provided on the driving block 32, and the slide groove 401 is provided on the connecting rod structure 40. Under the drive of the driving assembly 31, the connecting rod 321 on the driving block 32 abuts against the groove wall of the slide groove 401, thereby applying a force to the connecting rod structure 40, and the position of the force is at a distance from the axis around which the mounting member 20 flips relative to the fixed plate 10, thereby forming a torque, and under the action of the torque, the mounting member 20 flips relative to the fixed plate 10. In other embodiments, the connecting rod 321 can also be provided on the connecting rod structure 40, and the slide groove 401 can also be provided on the driving block 32, and the above-mentioned effect can also be achieved.

[0029] It is understandable that the existence of the connecting rod structure 40 can make the axis around which the mounting member 20 flips relative to the fixed plate 10 have a greater distance from the force position, that is, the mounting member 20 has a larger force arm during the flipping process relative to the fixed plate 10, which reduces the driving force requirements of the driving component 31 and improves the strength reliability. At the same time, the mounting member 20 and the push-pull mechanism 30 are arranged on opposite sides of the fixed plate 10, so that the push-pull mechanism 30 can be hidden inside, and the appearance of the device is relatively neat.

[0030] In some embodiments, the screen flipping device 100 includes a controller, which is electrically connected to the driving component 31. The controller is used to receive user instructions and control the driving component 31 to drive the driving block 32 to move a certain distance along a straight line according to the user's instructions, so that the mounting member 20 can drive the display screen to flip relative to the fixed plate 10 to the expected opening and closing angle.

[0031] By setting a push-pull mechanism 30 and a connecting rod structure 40, the connecting rod structure 40 is fixedly connected to the mounting member 20, and the driving block 32 in the push-pull mechanism 30 is connected to the connecting rod structure 40 through a connecting rod 321 and a slide groove 401. The driving assembly 31 in the push-pull mechanism 30 can drive the driving block 32 to move linearly, driving the mounting member 20 and the display screen to flip relative to the fixed plate 10, thereby realizing automatic adjustment of the opening and closing angle of the display screen, which is simpler than the traditional manual adjustment method. At the same time, the connecting rod structure 40 and the driving block 32 are transmitted by the connecting rod 321 and the slide groove 401. When the driving block 32 moves linearly, the connecting rod 321 abuts against the groove wall of the slide groove 401 and slides along the groove wall, which can ensure that the mounting member 20 always has a large force arm during the flipping process relative to the fixed plate 10, thereby increasing the strength reliability.

[0032] In one embodiment of this implementation, please refer to Figures 2 to 4 , Figure 4 yes Figure 1The screen flip device 100 is a three-dimensional structural diagram in a disassembled state. The push-pull mechanism 30 includes a mounting bracket 33, the mounting bracket 33 is fixed to the fixed plate 10, the driving component 31 is mounted on the mounting bracket 33, and the mounting bracket 33 is rotatably connected to the mounting member 20. It can be understood that by mounting the driving component 31 on the mounting bracket 33 and arranging the mounting member 20 to be rotatably connected to the mounting bracket 33, the relative positions of the driving block 32 and the connecting rod structure 40 are relatively consistent, which can ensure that the displacement of the driving block 32 and the opening angle of the mounting member 20 relative to the fixed plate 10 have a relatively accurate correlation.

[0033] In one embodiment of this implementation, please refer to Figure 4 and Figure 5 , Figure 5 yes Figure 1 The three-dimensional structure diagram of the mounting member 20, part of the mounting bracket 33 and the connecting rod structure 40 of the screen flip device 100 in the exploded state. The mounting member 20 is provided with a mounting groove 202, and the mounting member 20 is provided with a rotating shaft 21 located in the mounting groove 202. The mounting bracket 33 extends into the mounting groove 202 and is provided with a rotating hole 331, and the rotating shaft 21 is rotatably matched with the rotating hole 331. Specifically, the mounting groove 202 is provided on the surface of the mounting member 20 facing the fixed plate 10 and extends to the peripheral side of the mounting member 20. The rotating shaft 21 is arranged in the mounting groove 202 and is spaced apart from the groove wall of the mounting groove 202. In order to facilitate the installation of the driving component 31, the mounting bracket 33 is fixed to the side of the fixed plate 10 facing away from the mounting member 20, and a part of the mounting bracket 33 passes through the fixed plate 10 and extends into the mounting groove 202, and the part is provided with a rotating hole 331, and the rotating shaft 21 is rotatably matched with the rotating hole 331, thereby realizing the rotation connection between the mounting member 20 and the fixed plate 10. Such an arrangement can better hide the mounting bracket 33 in the mounting groove 202 of the mounting member 20. When the mounting member 20 is flipped relative to the fixing plate 10, the mounting bracket 33 is not easily visible to the user, making the appearance of the device neater.

[0034] In one embodiment of this implementation, please refer to Figure 3 and Figure 4The driving assembly 31 includes a driving motor 311 and a screw rod 312. The driving motor 311 is mounted on the mounting bracket 33 and connected to the screw rod 312. The screw rod 312 is rotationally matched with the mounting bracket 33 and threadedly matched with the driving block 32. The driving block 32 is slidingly matched with the mounting bracket 33. The driving motor 311 can drive the screw rod 312 to rotate, so as to drive the driving block 32 to slide relative to the mounting bracket 33. Specifically, the driving motor 311 is fixed to the mounting bracket 33 by screws, one end of the screw rod 312 is meshed with the output shaft of the driving motor 311, so that the driving motor 311 can drive the screw rod 312 to rotate around its own axis, and the other end of the screw rod 312 is threadedly matched with the driving block 32, so that the rotational motion of the screw rod 312 can be converted into the linear motion of the driving block 32. It is understandable that the screw rod 312 and the drive motor 311 are both mounted on the mounting bracket 33, which helps the output shaft of the drive motor 311 to mesh better with the screw rod 312, and the screw rod 312 and the mounting member 20 are both mounted on the mounting bracket 33, which helps the drive block 32 and the connecting rod structure 40 to cooperate better. At the same time, the self-locking characteristics of the screw rod 312 and the drive block 32 can be used to fix the opening and closing angle of the mounting member 20 and the fixing plate 10, which is more stable and reliable than the traditional solution of fixing by friction.

[0035] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 The mounting bracket 33 is provided with a mounting hole 332, and the driving assembly 31 includes a bearing 313, the outer ring of the bearing 313 is fixed to the mounting hole 332, and the inner ring of the bearing 313 is fixedly connected to the screw rod 312. Such an arrangement can reduce the friction between the screw rod 312 and the mounting bracket 33. Specifically, the number of the bearings 313 is two, and the two bearings 313 are arranged at intervals along the axial direction of the screw rod 312, and are respectively located on both sides of the gear teeth meshing with the screw rod 312 and the driving motor 311, so as to improve the reliability of the rotational connection between the screw rod 312 and the mounting bracket 33.

[0036] In one embodiment of this implementation, please refer to Figure 4 and Figure 6 , Figure 6 yes Figure 1Schematic diagram of the three-dimensional structure of the push-pull mechanism 30 of the screen flipping device 100 in the disassembled state. The mounting bracket 33 is provided with a guide rail 333, and the extension direction of the guide rail 333 is parallel to the extension direction of the screw rod 312. The driving block 32 is provided with a guide groove 322, and the guide rail 333 and the guide groove 322 are slidably matched. Specifically, the guide rail 333 and the mounting bracket 33 are split mechanisms, and the guide rail 333 is fixed to the mounting bracket 33 by screws. By providing the guide rail 333 on the mounting bracket 33 and providing the guide groove 322 on the driving block 32, the guide rail 333 and the guide groove 322 are slidably matched, and the rotation of the driving block 32 can be limited in one direction, and the movement accuracy of the driving block 32 can be effectively improved in the other direction.

[0037] In this embodiment, the mounting bracket 33 is provided with limiting protrusions 334 , and the limiting protrusions 334 are located at both ends of the guide rail 333 to limit the driving block 32 from leaving the guide rail 333 .

[0038] In one embodiment of this implementation, please refer to Figure 4 and Figure 6 The mounting bracket 33 includes a fixing cover 3302, a fixing seat 3301 and a connecting seat 3303. The fixing cover 3302 and the fixing seat 3301 enclose a mounting hole 332. One end of the connecting seat 3303 is connected to the fixing seat 3301. The other end of the connecting seat 3303 passes through the avoidance groove 101 provided by the fixing plate 10 and extends into the mounting groove 202, and a rotation hole 331 is provided. One side of the fixing cover 3302 is fixedly connected to the fixing plate 10, and the other side of the fixing cover 3302 is fixed to the fixing seat 3301 by screws. The guide rail 333 is arranged on the fixing seat 3301. In this way, the difficulty of assembling the mounting bracket 33 with the push-pull mechanism 30 and the mounting member 20 can be reduced, and the connecting seat 3303 can be hidden in the avoidance groove 101 and the mounting groove 202, which is conducive to making the appearance of the device neat.

[0039] In this embodiment, the connecting rod structure 40 is provided with two slide grooves 401, and the driving block 32 is provided with two connecting rods 321, and the two connecting rods 321 respectively extend into the two slide grooves 401, the middle part of the connecting rod structure 40 is hollowed out, and the fixing plate 10 is provided with a baffle 11, and the baffle 11 is located in the center of the avoidance groove 101, and the baffle 11 extends into the hollow area of ​​the connecting rod structure 40 to prevent external dust and other debris from entering the push-pull mechanism 30.

[0040] In one embodiment of this implementation, please refer to Figure 3 and Figure 7 , Figure 7 yes Figure 1Schematic diagram of the three-dimensional structure of the driving block 32 and the connecting rod structure 40 of the screen flipping device 100 in a cross-sectional state. The groove wall includes a first side wall 4011 and a second side wall 4012 opposite to each other, and the mounting member 20 has an extended position and a closed position relative to the fixed plate 10. When the mounting member 20 flips from the extended position to the closed position, the connecting rod 321 abuts against the first side wall 4011 and slides relative to the slide groove 401 in a first direction; when the mounting member 20 flips from the closed position to the extended position, the connecting rod 321 abuts against the second side wall 4012 and slides relative to the slide groove 401 in a second direction, wherein the second direction is opposite to the first direction. With such a configuration, the driving motor 311 can drive the driving block 32 to move in the opposite direction to drive the mounting member 20 to switch between the extended position and the closed position.

[0041] In this embodiment, the relative angle between the mounting member 20 and the fixing plate 10 is 60° when the mounting member 20 is in the extended position, that is, the maximum opening angle is 60°, and the relative angle between the mounting member 20 and the fixing plate 10 is 0° when the mounting member 20 is in the closed position, that is, the minimum opening angle is 0°. The total stroke of the screw rod 312 is 12.6 mm, and the stroke of the screw rod 312 and the opening angle of the mounting member 20 have a suitable ratio.

[0042] In one embodiment of this implementation, please refer to Figure 3 and Figure 7 When the mounting member 20 is in the closed position, the first side wall 4011 is perpendicular to the movement direction of the driving block 32. In this way, the force between the driving block 32 and the first side wall 4011 is perpendicular to the first side wall 4011, and the mounting member 20 can be better turned over in the closed position.

[0043] In one embodiment of this implementation, please refer to Figure 3 and Figure 7 , the first side wall 4011 and the second side wall 4012 are parallel, and the connecting rod 321 abuts against both the first side wall 4011 and the second side wall 4012. This arrangement facilitates the driving block 32 to transmit the force to the connecting rod structure 40 through the connecting rod 321, and after the mounting member 20 is flipped relative to the fixing plate 10, the mounting member 20 will not shake, which is conducive to improving user experience.

[0044] In this embodiment, the connecting rod 321 has a cylindrical surface, and two sides of the cylindrical surface in the radial direction are respectively in contact with the first side wall 4011 and the second side wall 4012 to reduce the friction between the connecting rod 321 and the sliding groove 401 .
