[0048] The following refers to Figures 1-10 Describe the adjusting device 100 and the backlash elimination structure 30 according to an embodiment of the present utility model.

[0049] According to an embodiment of the present utility model, the backlash elimination structure has a mounting portion, an abutting portion, and an elastic member 31. The abutting portion is used to abut against the member to be backlash-eliminated 20. The abutting portion includes a main body 33 and a movable arm 32. The movable arm 32 is connected to the main body. The movable arm 32 can move relative to the main body 33. The elastic member 31 is mounted on the mounting portion, and the elastic member 31 cooperates with the movable arm 32 such that the free end of the movable arm 32 has a tendency to move away from the mounting portion to abut against the member to be backlash-eliminated 20. That is, through the cooperation of the elastic member 31 and the movable arm 32, under the elastic force of the elastic member 31, the movable arm 32 always has a tendency to abut against the member to be backlash-eliminated 20. The member to be backlash-eliminated 20 is more stable when subjected to an external abutting force, and the probability of shaking can be reduced.

[0050] The anti-play member 20 can be installed on a structural member, for example, installed in the base body 10. The base body 10 is also provided with a mating portion 11, and the anti-play member 20 can cooperate with the mating portion 11. The free end of the movable arm 32 has a tendency to abut against the anti-play member 20. Thus, the anti-play structure 30 can apply a force to the anti-play member 20 in the direction close to the mating portion 11, which can reduce the gap between the anti-play member 20 and the mating portion 11, reduce the probability of the anti-play member 20 shaking, and improve the stability of the structure.

[0051] According to the anti-play structure 30 of the embodiment of the present invention, the free end of the movable arm 32 can abut against the anti-play member 20 to apply a force to the anti-play member 20, thereby reducing the gap between the anti-play member 20 and its mating portion, reducing the probability of the anti-play member 20 shaking, and improving the stability of the structure; the overall structure of the anti-play structure 30 is simple, with few components, convenient for installation and disassembly, and convenient for maintenance and replacement of components.

[0052] According to an embodiment of the present invention, the adjusting device 100 includes: a base body 10 and an anti-play member 20. The base body 10 has a mating portion 11, and the anti-play member 20 is rotatably arranged on the base body 10 and cooperates with the mating portion 11.

[0053] The anti-play structure 30 can be arranged on the base body 10. The movable arm 32 of the anti-play structure 30 is adapted to abut against the anti-play member 20, and the movable arm 32 is adapted to apply a force to the anti-play member 20 in the direction close to the mating portion 11 under the action of the elastic member 31.

[0054] It can be understood that the anti-play member 20 is arranged on the base body 10 and the anti-play member 20 cooperates with the mating portion 11, so that the anti-play member 20 can rotate relative to the base body 10. The adjusting device 100 can be a shaftless rotation structure. When the anti-play member 20 is installed on the base body 10, there may be a certain gap between the anti-play member 20 and the mating portion 11. This gap can be an assembly gap, a part size error gap, or a gap generated by the cooperation of the two, and this gap will cause the anti-play member 20 to shake.

[0055] Therefore, in this embodiment, a backlash elimination structure 30 is provided on the seat body 10. The movable arm 32 can abut against the component 20 to be backlash-eliminated, and apply a force to the component 20 to be backlash-eliminated, thereby reducing the gap between the component 20 to be backlash-eliminated and the mating portion 11. For example, during the rotation of the component 20 to be backlash-eliminated, the backlash elimination structure 30 can apply a force to the component 20 to be backlash-eliminated in the direction close to the mating portion 11, reducing the gap between the component 20 to be backlash-eliminated and the mating portion 11, and reducing the probability of the component 20 to be backlash-eliminated shaking in other directions during rotation, improving the reliability during the rotation process; or when the component 20 to be backlash-eliminated is static, the backlash elimination structure 30 can also apply a force to the component 20 to be backlash-eliminated in the direction close to the mating portion 11, reducing the gap between the component 20 to be backlash-eliminated and the mating portion 11, keeping the component 20 to be backlash-eliminated in a static state, reducing the probability of the component 20 to be backlash-eliminated shaking, and improving the stability.

[0056] The elastic member 31 applies a pressure to the movable arm 32, so that the outer surface of the movable arm 32 is always in close contact with the component 20 to be backlash-eliminated and is acted with a pressure, thereby eliminating the gap between the component 20 to be backlash-eliminated and the mating member 11, effectively reducing the shaking of the component 20 to be backlash-eliminated caused by the existence of the gap, and also avoiding abnormal wear caused by impact at the mating portion between the mating portion 11 and the component 20 to be backlash-eliminated under the condition of load impact. The mating portion 11 can be a gear, thereby protecting the accuracy of the gear transmission.

[0057] Wherein, the elastic member 31 and the movable arm 32 can be connected by fasteners, or can be connected by glue, double-sided tape, ultrasonic welding, hot melting, etc., or at least a part of the elastic member 31 can be embedded in the movable arm 32, that is, the elastic member 31 is embedded in the movable arm 32 to form an integral part.

[0058] By adopting the combination of the elastic member 31 and the movable arm 32, the backlash elimination structure 30 has a simple structure, low cost, and can flexibly adjust parameters such as the material, thickness, and external dimension of the elastic member 31 and the movable arm 32 according to the load condition.

[0059] It should be noted that the backlash elimination structure 30 here can be a combination with an elastic member 31, or can be an integral structural member. The backlash elimination structure 30 can be directly fixed on the seat body 10, which is convenient for the installation and disassembly of the backlash elimination structure 30, and is convenient for maintenance and replacement, etc.

[0060] According to the adjusting device 100 of the embodiment of the present invention, by providing the backlash elimination structure 30 to apply a force to the component 20 to be backlash-eliminated in the direction close to the mating portion 11, the gap between the component 20 to be backlash-eliminated and the mating portion 11 can be reduced, the probability of the component 20 to be backlash-eliminated shaking can be reduced, and the stability of the structure can be improved; by arranging the backlash elimination structure 30 on the seat body 10, it is convenient for the installation and disassembly of the backlash elimination structure 30, and is convenient for maintenance and replacement, etc.

[0061] As Figure 3 shown, in some embodiments, the abutting portion is provided with a limiting groove 32, the elastic member 31 is disposed on a side of the abutting portion facing away from the member 20 to be clearance eliminated, and an end of the elastic member 31 extends to the limiting groove 321. Thus, the limiting groove 321 can play a certain limiting role on the end of the elastic member 31, reducing the probability of the elastic member 31 shaking and shifting.

[0062] In some embodiments, a part of the bottom of the limiting groove 31 forms the movable arm 32. That is to say, in the assembled state of the elastic member 31 and the movable arm 32, the end of the elastic member 31 can press on the movable arm 32, applying a pressure to the movable arm 32. After the other surface of the movable arm 32 is worn, due to the acting force of the elastic member 31, the worn surface of the movable arm 32 still tightly abuts against the surface of the member 31 to be clearance eliminated, avoiding the generation of a gap between the member 20 to be clearance eliminated and the mating portion 11 to a certain extent.

[0063] As Figure 3 and Figure 6 shown, the elastic member 31 forms a shape arched toward a side away from the movable arm 32. Here, the elastic member 31 can be designed as a sheet or a plate itself. After the elastic member 31 is installed on the seat body 10, the elastic member 31 arches to achieve pre-deformation, causing the elastic member 31 to generate an elastic force. One end or both ends of the elastic member 31 can press on the limiting groove 321 on one side of the movable arm 32. Thus, the elastic member 31 can apply a force to the movable arm 32 in a direction close to the member 20 to be clearance eliminated through the elastic force, so as to apply a force to the member 20 to be clearance eliminated in a direction close to the mating portion 11.

[0064] Among them, the arched shape formed by the elastic member 31 can be that the elastic member 31 integrally forms an arc, or can form a shape in which a plurality of planes are sequentially inclined and connected, or can also be a combined shape of a plane and a curved surface.

[0065] As Figure 7 shown, in some embodiments, there are two movable arms 32, and both ends of the elastic member 31 respectively abut against the corresponding movable arms 32. Thus, the positions applying a force to the member 20 to be clearance eliminated are increased, the acting range on the member 20 to be clearance eliminated is improved, and further the stability of the member 20 to be clearance eliminated is improved.

[0066] In some examples, the material of the elastic member 31 can be plastic or metal, and the thickness of the elastic member 31 is determined according to the actual load required. Preferably, the thickness is greater than 0.05 mm; the elastic member 31 can select a suitable material, thickness, and radian according to different loads to ensure that the elastic member 31 can ensure the normal operation of the product under the elastic performance.

[0067] In some embodiments, the main body 33 is provided with a mounting portion, and the main body 33 can be mounted on the base 10 of the adjusting device 100. The elastic member 31 is provided on the main body 33, so that the elastic member 31 is directly mounted on the abutting portion, reducing the number of components and facilitating installation. At least a part of the elastic member 31 can extend to the side of the movable arm 32 away from the clearance eliminating member 20. Of course, the elastic member 31 can also be mounted on other structural members.

[0068] Among them, the main body 33 can be made of wear-resistant material. The main body 33 and the movable arm 32 can be an integral part. The movable arm 32 can be one or more. The outer arc of the movable arm 32 can match the outer arc of the clearance eliminating member 20. The main body 33 can adjust parameters such as material, thickness, and the length of the movable arm 32 according to the actual load situation, so that the movable arm 32 fits closely with the clearance eliminating member 20 and the acting force is uniform.

[0069] The main body 33 has a mounting hole 333. The main body 33 can be fixed on the base 10 by passing a fastener 34 through the mounting hole 333. The elastic member 31 can be mounted on the main body 33, and the two can be movably connected or fixedly connected. The end of the elastic member 31 presses on the movable arm 32. The elastic member 31 can be one or more.

[0070] As Figure 8 shown, in some embodiments, the main body 33 has a positioning post 331, and the elastic member 31 has a positioning hole 311. The positioning post 331 is inserted and matched with the positioning hole 311, or the main body 33 has a positioning hole 311 and the elastic member 31 has a positioning post 331, thereby realizing the cooperation between the elastic member 31 and the main body 33, which is convenient for installation. After the two are assembled and installed on the base 10, the positioning post 331 can abut against the base 10, which can limit the disengagement of the positioning post 331 and the positioning hole 311, thereby improving the reliability of the cooperation between the main body 33 and the elastic member 31.

[0071] As Figure 8 shown, in some embodiments, a boss 332 is provided on the side of the main body 33 away from the clearance eliminating member 20, and the positioning post 331 is provided on the boss 332. The boss 332 can be provided in the middle of the main body 33, and the positioning hole 311 is correspondingly provided in the middle of the elastic member 31. Thus, after the positioning post 331 is inserted and matched with the positioning hole 311 on the elastic member 31, the distance between the middle of the elastic member 31 and the middle of the main body 33 can be increased, the bending degree of the elastic member 31 can be increased, and the elastic force of the elastic member 31 can be improved.

[0072] As Figure 6As shown, in some embodiments, the elastic member 31 includes a planar segment 312 and a bent segment 313. A positioning hole 311 is provided on the planar segment 312. One end of the bent segment 313 is connected to the planar segment 312, and the other end of the bent segment 313 is adapted to abut against the movable arm 32. By providing the positioning hole 311 on the planar segment 312, the probability of the aperture of the positioning hole 311 changing due to the deformation of the elastic member 31 can be reduced. Furthermore, the probability of the cooperation between the elastic member 31 and the body 33 being blocked and affecting the deformation of the elastic member 31 can be reduced, so that the bent segment 313 of the elastic member 31 can always cooperate with the movable arm 32.

[0073] As Figure 9 shown, in some embodiments, the clearance eliminating member 20 defines an installation groove 23, and at least a part of the clearance eliminating structure 30 is disposed in the installation groove 23, and the clearance eliminating structure 30 is in sliding fit with the installation groove 23. That is, when the clearance eliminating member 20 rotates, the clearance eliminating structure 30 can reduce the rotational resistance of the clearance eliminating member 20 through sliding fit with the installation groove 23, facilitating the rotation of the clearance eliminating member 20. Moreover, the outer shape of the clearance eliminating structure 30 matches the installation groove 23 of the clearance eliminating member 20, and the clearance in the rotational axis direction of the clearance eliminating member can also be eliminated, reducing the axial wobbling of the clearance eliminating member 20 caused by the existence of the clearance. Thus, under the action of the clearance eliminating structure 30, the structural clearances in two directions can be eliminated, further improving the stability of the clearance eliminating member 20.

[0074] In some examples, sliding members are further provided on one side or both sides of the clearance eliminating member 20 in the axial direction, and sliding grooves are provided on the seat body 10. Through the sliding fit between the sliding members and the sliding grooves, the smoothness and reliability of the rotation of the clearance eliminating member 20 are improved.

[0075] As Figure 9 and Figure 10 shown, in some embodiments, the engaging portion 11 is a gear, and engaging teeth 211 are provided on the clearance eliminating member 20. The clearance eliminating member 20 meshes with the gear. Thus, the clearance eliminating member 20 can rotate under the drive of the gear, or the clearance eliminating member 20 can drive the gear to rotate when it rotates.

[0076] As Figure 10 shown, in some embodiments, the clearance eliminating member 20 includes a rotating body 21, the rotating body 21 forms an arc, and engaging teeth 211 are provided on the rotating body 21. The clearance eliminating member 20 is adapted to rotate around the center of the arc of the rotating body 21. That is, the adjusting device 100 is a shaftless rotation structure, and the clearance eliminating member 20 rotates along a virtual axis, and the virtual axis passes through the center of the arc of the rotating body 21.

[0077] The clearance eliminating member 20 further includes a mounting bracket 22. The mounting bracket 22 can be connected to one end of the rotating body 21, and structures such as a display screen 50 can be mounted on the mounting bracket 22.

[0078] As shown Figure 2 In some embodiments, as shown, the backlash elimination structure 30 and the gear are disposed on both sides of the member 20 to be backlash-eliminated. Thus, the backlash elimination structure 30 can also apply a force to the member 20 to be backlash-eliminated in the direction close to the mating portion 11, reducing the gap between the member 20 to be backlash-eliminated and the mating portion 11.

[0079] As shown Figure 4 、 Figure 11 and Figure 12 In some embodiments, as shown, the adjusting device 100 further includes: a driving motor 40, an output shaft of the driving motor 40 is connected to the gear for driving the gear to rotate, the gear meshes with the member 30 to be backlash-eliminated, and the display screen 50 is connected to the member 30 to be backlash-eliminated. Thus, when the driving motor 40 operates, the driving motor 40 drives the gear to rotate, driving the member 20 to be backlash-eliminated and the display screen 50 to rotate along an arc surface, realizing the switching of the display screen 50 between the first position and the second position. Among them, in the first position, the display screen 50 can be in a contracted state, and in the second position, the display screen 50 can be in an extended state.

[0080] As shown Figure 11 and Figure 12 The display screen assembly 200 according to an embodiment of the present invention includes a display screen 50 and an adjusting device 100 according to an embodiment of the present invention. The display screen 50 is disposed on the member 20 to be backlash-eliminated. By adopting the above adjusting device 100, the probability of the display screen 50 shaking can be reduced, and the structural stability of the display screen assembly 200 can be improved.

[0081] As shown Figure 13 The vehicle 300 according to an embodiment of the present invention includes a display screen assembly 200 according to an embodiment of the present invention. By adopting the above display screen assembly 200, the probability of the display screen 50 shaking can be reduced, and the user experience of the vehicle 300 can be improved.
