[0044] In the related art, when a display screen mounted on a vehicle (such as a car, a spacecraft, a spaceship, a ship, etc.) is flipped, the flipping device usually uses a single-sided motor to drive the display screen mounted on the flipping device to flip.

[0045] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0046] First, please refer to Figures 1 to 3The present application discloses a flipping device 100 for a display screen, comprising a bracket 1 and a driving mechanism 2, wherein the bracket 1 can be used to mount a display screen, and the driving mechanism 2 comprises a motor 20 and a one-way locking module 21. It can be understood that the motor 20 is connected to the one-way locking module 21, and the one-way locking module 21 is further connected to the bracket 1, so that the power of the motor 20 is transmitted to the bracket 1 through the one-way locking module 21, thereby driving the bracket 1 and the display screen on the bracket 1 to flip.

[0047] The one-way locking module 21 is arranged between the motor 20 and the bracket 1. The one-way locking module 21 includes a driving shaft 211, a driven shaft 212 and a limiting structure 213. The driving shaft 211 is connected to the motor 20, and the driven shaft 212 is connected to the driving shaft 211 and the bracket 1. The driving shaft 211 is used to transmit the power of the motor 20 to the driven shaft 212. A first movable connection part 211a is provided at one end where the driving shaft 211 and the driven shaft 212 are connected. A second movable connection part 212a is provided on the driven shaft 212 corresponding to the first movable connection part 211a, and an active space 21a is formed between the second movable connection part 212a and the first movable connection part 211a. The limiting structure 213 is provided in the active space 21a. The one-way locking module 21 has a power output state and a hovering state. In the power output state, the limiting structure 213 is configured to connect the first movable connection part 211a with the second movable connection part 212a, so that the rotation of the active shaft 211 is transmitted to the driven shaft 212, so that the driven shaft 212 can drive the bracket 1 to flip. In the hovering state, the limiting structure 213 is configured to limit the position of the second movable connection part 212a, so that the second movable connection part 212a is separated from the first movable connection part 211a, so as to block the rotation of the driven shaft 212 from being transmitted to the active shaft 211.

[0048] Specifically, when the motor 20 drives the bracket 1 to rotate through the one-way locking module 21, the first movable connection part 211a of the active shaft 211 moves in the active space 21a and abuts against the limiting structure 213. Thus, the first movable connection part 211a drives the limiting structure 213 to abut against the second movable connection part 212a, so that the power can be transmitted from the active shaft 211 to the driven shaft 212, and finally to the bracket 1, so as to drive the bracket 1 to flip in the power output state. In the hovering state, when the driven shaft 212 rotates due to the shaking of the bracket 1, the second movable connection part 212a on the driven shaft 212 is connected to the limiting structure 213, and the movement of the second movable connection part 212a is blocked by the limiting structure 213, so that the second movable connection part 212a cannot be connected to the first movable connection part 211a through the limiting structure 213. In this way, the shaking generated by the bracket 1 when mounting the display screen is restrained by the driven shaft 212 and the limit structure 213, and cannot be further transmitted to the driving shaft 211 and the motor 20, thereby avoiding the shaking of the flip device 100 as a whole in the hovering state, so that the flip device 100 still has a good hovering effect when mounting the display screen, reducing the shaking of the display screen when hovering after flipping, and improving the viewing experience of the display screen. Moreover, when the motor 20 drives the bracket 1 to flip, it can still transmit power well.

[0049] Please combine Figure 4 As shown, in some embodiments, the first movable connection part 211a and / or the second movable connection part 212a can rotate around the axial direction of the driven shaft 212, and the second movable connection part 212a and the limiting structure 213 are provided on both sides of the first movable connection part 211a around the axial direction of the driven shaft 212. In this way, when the driving shaft 211 rotates forward and reversely around the axial direction of the driven shaft 212, the driving shaft 211 can transmit power to the driven shaft 212 to achieve the flipping of the bracket 1. When the driven shaft 212 rotates forward and reversely around its axial direction, the limiting structure 213 limits the driven shaft 212 from transmitting power to the driving shaft 211, so that the shaking of the bracket 1 in the axial direction around the driven shaft 212 will be limited by the limiting structure 213 to maintain a stable hovering state.

[0050] In order to further enhance the power effect transmitted from the driving shaft 211 to the driven shaft 212 and to limit the power transmission effect of the driven shaft 212 to the driving shaft 211, in some embodiments, the first movable connection part 211a includes a plurality of bosses around the axial direction of the driving shaft 211, and a first interval 211b is provided between the two bosses. The second movable connection part 212a includes a plurality of flanges around the axial direction of the driven shaft 212, and a second interval 212b is provided between the two flanges. Each column is correspondingly arranged at the second interval 212b, and each flange is correspondingly arranged at the first interval 211b, so that each boss and each flange are staggered in the axial direction around the driven shaft. In other words, the driving shaft 211 and the driven shaft 212 are connected along the axial direction of the driving shaft 211 or the axial direction of the driven shaft 212, at which time each boss is inserted into the second interval 212b along the axial direction, and each flange is inserted into the first interval 211b along the axial direction. It is understandable that an active space 21a is formed between the flange and the boss, and when the driving shaft 211 or the driven shaft 212 rotates, the flange or the boss can move in the active space 21a. In one example, when the motor 20 drives the driving shaft 211 to rotate, each boss is driven and connected to the flange through the limiting structure 213, so that the driving force of the motor 20 can be transmitted from each column to each flange, multi-point connection, multi-point transmission, and then drive the driven shaft 212 to rotate. Therefore, when the motor 20 transmits power through the one-way locking module 21, it has a good power transmission effect. In another example, in the hovering state, when the bracket 1 shakes due to the mounting of the display screen, the driven shaft 212 shakes or rotates, causing the flange to move in the activity space 21a. At this time, the limiting structure 213 stops the movement of the flange, so that the flange cannot contact the boss, and the shaking of the driven shaft 212 cannot be transmitted to the active shaft 211, thereby avoiding shaking of the entire flip device 100 and affecting the hovering effect, and multiple flanges are all stopped by the limiting structure 213, thereby more effectively locking the driven shaft 212, so that the rotation or shaking of the driven shaft 212 cannot be further transmitted.

[0051] Optionally, the number of the flanges and the bosses may be, but not limited to, three, four, five, etc., and this application does not make any specific limitation here.

[0052] In addition, in other embodiments, the first movable connection portion 211a may also be a flange, and the second movable connection portion 212a may be a convex column, which can be adjusted according to actual conditions, and this embodiment does not make any specific limitations on this.

[0053] Please combine Figure 4In some embodiments, the limiting structure 213 includes a locking portion 2131 and a movable component 2132. The movable component 2132 is arranged on one side of the movable space 21a close to the second movable connection portion 212a and is connected to the second movable connection portion 212a. The locking portion 2131 is arranged between the movable component 2132 and the first movable connection portion 211a, and the locking portion 2131 and the first movable connection portion 211a are spaced apart.

[0054] In one example, in the power output state, the movable assembly 2132 connects the first movable connection part 211a and the second movable connection part 212a, so that the power of the driving shaft 211 is output to the driven shaft 212. That is, the first movable connection part 211a is indirectly connected to the second movable connection part 212a through the movable assembly 2132. When the first movable connection part 211a moves toward the movable assembly 2132, the locking part 2131 does not block the movement of the first movable connection part 211a, so that the power can be well transmitted from the driving shaft 211 to the driven shaft 212.

[0055] In another example, in the hovering state, the movable component 2132 is stuck to the locking portion 2131, so that the first movable connection portion 211a is spaced from the movable component 2132. In the hovering state, even if the second movable connection portion 212a is connected to the movable component 2132, so that the movable component 2132 moves toward the first movable connection portion 211a, the movable component 2132 will contact the locking portion 2131 and be locked by the locking portion 2131, so that the movable component 2132 cannot be connected to the first movable connection portion 211a. Therefore, the rotation transmitted from the driven shaft 212 cannot be transmitted to the driving shaft 211 through the movable component 2132, so that when the bracket 1 is mounted with the display screen, the shaking transmitted from the bracket 1 to the driven shaft 212 can also be locked, so that the flip device 100 as a whole remains in a stable state even when it is hovering.

[0056] Considering that the movable assembly 2132 and the locking portion 2131 may be worn when locked in the hovering state, and the two may generate noise due to the mutual friction when the driven shaft 212 moves. Based on this, in some embodiments, the movable assembly 2132 includes an elastic member 213a and a rolling member 213b, the elastic member 213a is connected to the second movable connection portion 212a, and the rolling member 213b is located between the elastic member 213a and the locking portion 2131. Specifically, in the power output state, the first movable connection portion 211a, the rolling member 213b and the elastic member 213a are connected in sequence, and in the hovering state, the rolling member 213b is connected to the elastic member 213a, and the rolling member 213b is locked in the locking portion 2131. It can be understood that the rolling member 213b can convert the movement of the movable assembly 2132 in the activity space 21a into rolling, reduce friction, and effectively reduce the wear of the rolling member 213b in the activity space 21a. The elastic member 213a has a certain damping effect, which can alleviate the shaking of the second movable connection part 212a caused by the bracket 1 in the hovering state, thereby improving the mounting effect.

[0057] exist Figure 4 In the figure, the axial direction of the driven shaft 212 is the direction indicated by X.

[0058] Optionally, the elastic member 213a may be, but not limited to, a spring or a spring, and the rolling member 213b may be, but not limited to, a ball or a roller, and the present application does not make any specific limitations thereto.

[0059] See also Figure 5 In some embodiments, the driving mechanism 2 further includes an encoder 22, which is connected to the driven shaft 212, and the encoder 22 is used to detect the hovering angle of the one-way locking module 21 in the hovering state. Specifically, the encoder 22 is connected to the driven shaft 212 through a gear 22a, that is, when the driven shaft 212 rotates to any hovering angle in the hovering state, the specific hovering angle can be transmitted to the encoder 22 through the gear 22a, so that the encoder 22 can detect the hovering angle of the driven shaft 212. For example, when the driven shaft 212 shakes or rotates in the hovering state due to the bracket 1 mounting the display screen, the hovering angle of the driven shaft 212 changes, and the change in the hovering angle is transmitted to the encoder 22 through the gear 22a. The encoder 22 senses the change in the gear 22a and locks or adjusts the gear 22a, so that the gear 22a locks the driven shaft 212 or adjusts the hovering state of the driven shaft 212, so that the shaking of the driven shaft 212 is reduced, and then the shaking of the bracket 1 is reduced, so that the flip device 100 as a whole maintains a good hovering effect.

[0060] In some embodiments, the drive mechanism 2 further includes a housing 23, in which a one-way locking module 21 and an encoder 22 are disposed, so that the one-way locking module 21 and the encoder 22 are integrally arranged. In this way, the one-way locking module 21 and the encoder 22 are compact in structure, and are also convenient for simultaneous installation and removal, thereby improving installation convenience.

[0061] See also Figure 6 In some embodiments, the driving mechanism 2 further includes a reduction box 24 and a coupling 25. The reduction box 24 has a power input end 241 and a power output end 242, and the coupling 25 has a first end 251 and a second end 252. The power input end 241 is connected to the motor 20, and the power output end 242 is connected to the first end 251 of the coupling 25, and the second end 252 of the coupling 25 is connected to the driving shaft 211. In the actual setting, the reduction box 24 is used to adjust the power output of the motor 20, and the faster speed of the motor 20 is adjusted to a lower speed output, so that the turning of the entire flipping device 100 is more stable, which is conducive to obtaining a better turning effect. The coupling 25 can adjust the coaxial deviation between the power output end 242 and the driving shaft 211 during installation, so that the power can still be better transferred to the bracket 1 during the turning process, which is conducive to meeting the error requirements during manufacturing.

[0062] Taking into account the possibility of mounting a heavy display screen, in some embodiments, the speed ratio between the power input end 241 and the power output end 242 may be 500:1-700:1. Specifically, the speed ratio between the power input end 241 and the power output end 242 may be 500:1, 550:1, 600:1 and 700:1. When mounting a heavier display screen, the load requirements for the entire flip device 100, especially the motor 20, are relatively high. Therefore, by adjusting the rotation ratio of the reduction box 24, the high speed of the motor 20 is adjusted to a lower speed. In this way, the low torque output by the motor 20 through the reduction box 24 is adjusted to a high torque, thereby improving the overall load capacity of the flip device 100, which is conducive to the flip device 100 mounting more display screens of different weights.

[0063] It is understandable that the motor 20, the reduction box 24, the coupling 25, the one-way locking module 21 and the bracket 1 can be connected by a connector (not shown). The motor 20, the reduction box 24, the coupling 25, the one-way locking module 21 and the bracket 1 are firmly connected by the connector, which is conducive to improving the stability and firmness of the flip device 100.

[0064] Optionally, the connecting member may be, but is not limited to, a screw, a rivet, etc., and this application does not make any specific limitation here.

[0065] Since this type of flipping device 100 usually adopts a single-sided suspension method, that is, only one side of the bracket 1 part of the flipping device 100 used to mount the display screen is connected to the driving mechanism 2, so that only one side of the bracket 1 is driven during the flipping process, and the other side will be affected by the gravity of the display screen. In this way, the forces on both sides of the bracket 1 are uneven, which affects the flipping effect of the bracket 1 when the display screen is mounted. In some embodiments, the driving mechanisms 2 are respectively provided on both sides of the bracket 1, and the axes of the driven shafts 212 of the two driving structures are located on the same straight line. The driving mechanisms 2 are provided on both sides of the bracket 1, and the load when the bracket 1 is mounted on the display screen can be distributed to the driving mechanisms 2 on both sides, so that the bracket 1 flips more smoothly, and the two driving mechanisms 2 share the load, which is conducive to the bracket 1 to mount a heavier display screen. In addition, the power of the two driving mechanisms 2 can be kept on the same straight line during flipping, so that the power input on both sides of the bracket 1 is more balanced, and the effect of the bracket 1 when flipping is more stable.

[0066] Second, see Figure 7 The present application discloses a carrier 200, which includes a carrier body 201 and a display screen flipping device 100 disclosed in the first aspect.

[0067] Since the vehicle 200 is prone to bumps during use, the flip device 100 used to flip the display screen in the vehicle 200 has a poor hovering effect and is prone to shaking due to bumps, resulting in a poor display effect when the display screen is mounted on the flip device 100. However, by using a flip device 100 for a display screen disclosed in the present application, the display screen can still maintain a good hovering effect when mounted on the flip device 100, avoiding excessive shaking that affects the display effect of the display screen, and improving the use experience of the passengers of the vehicle 200.

[0068] Optionally, the vehicle 200 may be, but is not limited to, a car, a spacecraft, a spaceship, a ship, etc., and this application does not make any specific limitation here.

[0069] The above is a detailed introduction to a flipping device and a carrier for a display screen disclosed in an embodiment of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the flipping device and a carrier for a display screen of the present application and its core idea. At the same time, for a person skilled in the art, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
