[0035] See also Figures 1 to 3 , Figure 1 1 is a schematic diagram of the three-dimensional structure of a screen flipping device 100 according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the three-dimensional structure of the screen flip device 100 from another perspective; Figure 3 yes Figure 1 Schematic diagram of the three-dimensional structure of the screen flipping device 100 in a cross-sectional state. An 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 mount a display screen (not shown). The push-pull mechanism 30 is installed on the side of the fixed plate 10 facing away from the mounting member 20. The push-pull mechanism 30 includes a driving assembly 31 and a driving block 32. 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 linearly, 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 .

[0036] Specifically, the fixed plate 10 can be part of the appearance of the electronic device, such as a decorative plate. The mounting member 20 is provided with an assembly slot 201 on the side facing away from the fixed plate 10, and the assembly slot 201 is used to mount the display screen. The drive assembly 31 can provide a driving force to the drive block 32 through a drive device such as an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, and a motor, so that the drive block 32 can reciprocate in a straight line. It is understood that the drive assembly 31 can apply two driving forces in opposite directions to the drive block 32, so that the drive block 32 can drive the fixed plate 10 to flip relative to the fixed plate 10 to close or unfold via the connecting rod structure 40.

[0037] 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.

[0038] In this embodiment, the connecting rod 321 is provided on the drive block 32, and the chute 401 is provided in the connecting rod structure 40. Driven by the drive assembly 31, the connecting rod 321 on the drive block 32 abuts against the wall of the chute 401, thereby applying a force to the connecting rod structure 40. The position of the force is spaced from the axis about which the mounting member 20 rotates relative to the fixed plate 10, thereby generating a torque that causes the mounting member 20 to rotate relative to the fixed plate 10. In other embodiments, the connecting rod 321 may be provided on the connecting rod structure 40, and the chute 401 may be provided on the drive block 32, to achieve the same effect.

[0039] It can be understood that the presence of the connecting rod structure 40 allows the axis about which the mounting member 20 rotates relative to the fixed plate 10 to be at a greater distance from the location of the force applied. This means that the mounting member 20 has a larger moment arm during its rotation relative to the fixed plate 10, reducing the driving force required of the drive assembly 31 and improving strength and reliability. Furthermore, the mounting member 20 and the push-pull mechanism 30 are located on opposite sides of the fixed plate 10, allowing the push-pull mechanism 30 to be concealed internally, resulting in a cleaner appearance for the device.

[0040] 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 in 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.

[0041] By providing a push-pull mechanism 30 and a connecting rod structure 40, the connecting rod structure 40 is fixedly connected to the mounting member 20. The driving block 32 in the push-pull mechanism 30 is connected to the connecting rod structure 40 via a connecting rod 321 and a slide 401. The driving assembly 31 in the push-pull mechanism 30 can drive the driving block 32 in a linear motion, causing the mounting member 20 and the display screen to flip relative to the fixed plate 10, thereby automatically adjusting the opening and closing angle of the display screen. This is simpler than traditional manual adjustment methods. Furthermore, the connecting rod structure 40 and the driving block 32 are driven by the connecting rod 321 and the slide 401. When the driving block 32 moves linearly, the connecting rod 321 abuts against and slides along the wall of the slide 401. This ensures that the mounting member 20 always has a large lever arm during the flipping process relative to the fixed plate 10, increasing strength and reliability.

[0042] In one embodiment of this embodiment, please refer toFigures 2 to 4 , Figure 4 yes Figure 1 A schematic diagram of the three-dimensional structure of the screen flip device 100 in a disassembled state. The push-pull mechanism 30 includes a mounting bracket 33, which is fixed to the fixed plate 10. The drive assembly 31 is mounted on the mounting bracket 33, and the mounting bracket 33 is rotatably connected to the mounting member 20. It will be understood that the mounting of the drive assembly 31 to the mounting bracket 33 and the rotatable connection of the mounting member 20 to the mounting bracket 33 ensure a relatively consistent relative position between the drive block 32 and the connecting rod structure 40, ensuring a relatively accurate correlation between the displacement of the drive block 32 and the opening angle of the mounting member 20 relative to the fixed plate 10.

[0043] In one embodiment of this embodiment, please refer to Figure 4 and Figure 5 , Figure 5 yes Figure 1 A schematic diagram of the disassembled three-dimensional structure of the screen flipping device 100, including the mounting member 20, a portion of the mounting bracket 33, and the connecting rod structure 40. The mounting member 20 defines a mounting slot 202, which is provided with a rotating shaft 21 positioned within the slot. The mounting bracket 33 extends into the slot 202 and defines a rotation hole 331, with which the rotating shaft 21 rotatably engages. Specifically, the slot 202 is defined on the surface of the mounting member 20 facing the fixed plate 10 and extends around the periphery of the mounting member 20. The rotating shaft 21 is disposed within the slot 202 and spaced from the slot walls. To facilitate installation of the drive assembly 31, the mounting bracket 33 is secured to the side of the fixed plate 10 facing away from the mounting member 20. A portion of the mounting bracket 33 extends through the fixed plate 10 and into the slot 202. This portion defines a rotation hole 331, with the rotating shaft 21 rotatably engaging the rotation hole 331, thereby achieving a rotational connection between the mounting member 20 and the fixed plate 10. Such a configuration 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 seen by the user, making the appearance of the device neater.

[0044] In one embodiment of this embodiment, please refer to Figure 3 and Figure 4The drive assembly 31 includes a drive motor 311 and a screw 312. The drive motor 311 is mounted on the mounting bracket 33 and connected to the screw 312. The screw 312 is rotationally engaged with the mounting bracket 33 and threadedly engaged with the drive block 32. The drive block 32 slides with the mounting bracket 33. The drive motor 311 can drive the screw 312 to rotate, thereby causing the drive block 32 to slide relative to the mounting bracket 33. Specifically, the drive motor 311 is fixed to the mounting bracket 33 by screws. One end of the screw 312 engages with the output shaft of the drive motor 311, so that the drive motor 311 can drive the screw 312 to rotate about its own axis. The other end of the screw 312 is threadedly engaged with the drive block 32, so that the rotational motion of the screw 312 can be converted into linear motion of the drive block 32. It is understood that the screw rod 312 and the drive motor 311 are both mounted on the mounting bracket 33, which facilitates better engagement between the output shaft of the drive motor 311 and the screw rod 312. Furthermore, the screw rod 312 and the mounting member 20 are both mounted on the mounting bracket 33, which facilitates better coordination between the drive block 32 and the connecting rod structure 40. Furthermore, the self-locking properties of the screw rod 312 and the drive block 32 can be utilized to secure the opening and closing angle of the mounting member 20 and the fixing plate 10, which is more stable and reliable than conventional solutions that rely on friction for securing.

[0045] In one embodiment of this embodiment, please refer to Figure 3 and Figure 4 The mounting bracket 33 defines a mounting hole 332. The drive 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. This arrangement reduces friction between the screw rod 312 and the mounting bracket 33. Specifically, there are two bearings 313, which are spaced apart along the axis of the screw rod 312 and located on either side of the gear teeth that mesh with the drive motor 311, thereby improving the reliability of the rotational connection between the screw rod 312 and the mounting bracket 33.

[0046] In one embodiment of this embodiment, 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 flip 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.

[0047] In this embodiment, the mounting bracket 33 is provided with limiting protrusions 334 . 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 .

[0048] In one embodiment of this embodiment, please refer to Figure 4 and Figure 6 The mounting bracket 33 includes a fixing cover 3302, a fixing base 3301, and a connecting base 3303. The fixing cover 3302 and the fixing base 3301 enclose a mounting hole 332. One end of the connecting base 3303 is connected to the fixing base 3301, and the other end of the connecting base 3303 passes through the avoidance groove 101 provided in the fixing plate 10 and extends into the mounting groove 202. A rotation hole 331 is provided in the connecting base 3303. 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 base 3301 by screws. The guide rail 333 is provided on the fixing base 3301. This arrangement can reduce the difficulty of assembling the mounting bracket 33 with the push-pull mechanism 30 and the mounting member 20, and the connecting base 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.

[0049] In this embodiment, the connecting rod structure 40 is provided with two sliding 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 sliding 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. 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.

[0050] In one embodiment of this embodiment, please refer to Figure 3 and Figure 7 , Figure 7 yes Figure 1A schematic diagram of the three-dimensional structure of the drive block 32 and connecting rod structure 40 of the screen flipping device 100 in a cross-sectional view. The slot wall includes a first side wall 4011 and a second side wall 4012 that oppose each other. 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 the first side wall 4011 and slides relative to the slide slot 401 in a first direction. When the mounting member 20 flips from the closed position to the extended position, the connecting rod 321 abuts the second side wall 4012 and slides relative to the slide slot 401 in a second direction, which is opposite to the first direction. This arrangement allows the drive motor 311 to drive the drive block 32 in opposite directions, thereby driving the mounting member 20 to switch between the extended and closed positions.

[0051] In this embodiment, the relative angle between the mounting member 20 and the fixed plate 10 in the extended position is 60°, meaning the maximum opening angle is 60°. In the closed position, the relative angle between the mounting member 20 and the fixed plate 10 is 0°, meaning the minimum opening angle is 0°. The total stroke of the screw rod 312 is 12.6 mm, creating a suitable ratio between the stroke of the screw rod 312 and the opening angle of the mounting member 20.

[0052] In one embodiment of this embodiment, 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 arrangement, the force exerted by the driving block 32 on the first side wall 4011 is perpendicular to the first side wall 4011, and the mounting member 20 can be better flipped in the closed position.

[0053] In one embodiment of this embodiment, 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 allows the driving block 32 to transmit the force to the connecting rod structure 40 via the connecting rod 321, and prevents the mounting member 20 from shaking after it is flipped relative to the fixing plate 10, thereby improving the user experience.

[0054] In this embodiment, the connecting rod 321 has a cylindrical surface, and two sides of the cylindrical surface in the radial direction respectively abut against 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 .

[0055] The present invention provides an electronic device. Figure 1The electronic device includes a display screen and a screen flipping device 100, wherein the display screen is mounted on a mounting member 20 of the screen flipping device 100. Specifically, the electronic device may be a smartphone, a smartwatch, a tablet computer, or the like. By incorporating the screen flipping device 100 provided in an embodiment of the present invention into the electronic device, the display screen can be automatically flipped, the opening and closing angle of the display screen can be adjusted more conveniently, and the user experience is improved.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention.
