Description

Technical Field

[0001] The utility model relates to the field of micro cameras, and particularly to a damping rotation structure of a micro camera. Background Art

[0002] At present, in application fields such as driving recorders and desktop cameras, micro camera devices need to support users to adjust the camera angle according to their own needs. In the above-mentioned usage environments, micro camera devices may be affected by external impacts, collisions, vibrations and other interferences. Therefore, in the angle rotation structure of current micro camera devices, interference fit rubber rings, rubber sleeves and other materials are usually used to increase the rotation damping to ensure the stability of the camera angle when users use it.

[0003] However, such a structural solution makes the rotation adjustment feel of users poor. During assembly, due to the interference of damping materials such as rubber rings on the rotation structure, the assembly is difficult and it is very difficult to ensure the consistency of the rotation damping feel in mass production, which affects the user experience and product reputation. Summary of the Utility Model

[0004] In view of the above technical problems, the utility model provides a damping rotation structure of a micro camera.

[0005] To solve the above technical problems, the utility model provides a damping rotation structure of a micro camera. The damping rotation structure of the micro camera includes: a rotating shaft, the inside of the rotating shaft is a hollow structure, a camera assembly, the camera assembly is arranged in the hollow structure, a rotating shaft bracket, the rotating shaft bracket is rotatably connected with the rotating shaft. Among them, at least one wave gear buckle is arranged on the rotating shaft, and a number of wave teeth are arranged in the rotating shaft bracket, and the wave gear buckle is clamped between the wave teeth.

[0006] In the damping rotation structure of the micro camera provided by the utility model, it may also have the following characteristics: the damping rotation structure of the micro camera further includes a rotating shaft cover, and the rotating shaft cover is fixedly connected with the rotating shaft.

[0007] In the damping rotation structure of the micro camera provided by the utility model, it may also have the following characteristics: the rotating shaft cover is fixed at the end port of the rotating shaft by screws.

[0008] In the damping rotation structure of the micro camera provided by the utility model, it may also have the following characteristics: the wave gear buckle is arranged at the end of the rotating shaft, and this end extends into the rotating shaft bracket.

[0009] In the damping rotation structure of the micro camera provided by the utility model, it may also have the following characteristics: the wave gear buckle is an elastic wave gear buckle.

[0010] In the damping rotation structure of the micro camera provided by the present utility model, it may further have the following feature: One end of the wave gear buckle is fixedly connected to the rotating shaft, and the other end is set to be suspended.

[0011] In the damping rotation structure of the micro camera provided by the present utility model, it may further have the following feature: The wave teeth are continuously and evenly distributed on the inner circumferential surface of the rotating shaft bracket.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the damping rotation structure of the micro camera of the present utility model, it includes a rotating shaft, a camera assembly, and a rotating shaft bracket. The inside of the rotating shaft is a hollow structure, the camera assembly is arranged inside the hollow structure, and the rotating shaft bracket is rotatably connected to the rotating shaft. Among them, at least one wave gear buckle is arranged on the rotating shaft, several wave teeth are arranged inside the rotating shaft bracket, and the wave gear buckle is engaged between the wave teeth. Based on this damping rotation structure, the angle adjustment of the camera assembly is realized through the rotational connection between the rotating shaft and the rotating shaft bracket. In this rotational connection, the rotational damping effect of the structure is realized by the collision and friction between the wave gear buckle on the rotating shaft and the wave teeth on the rotating shaft bracket. During rotation, the wave gear buckle and the wave teeth continuously come into contact and collide. The wave gear buckle undergoes elastic deformation during each collision and there is a friction effect with the top of the wave teeth. After stopping rotation, the buckle stays in the middle position between two wave teeth to maintain the current rotation angle. Therefore, the damping rotation structure lies in that without using any damping materials, the rotational damping effect is realized only through the elastic deformation of the rotating shaft structure and the internal structure shape of the rotating shaft bracket.

[0014] Therefore, this damping rotation structure not only reduces the use of rubber parts, reduces product costs, protects the environment, but also reduces the assembly steps and assembly difficulty of the micro camera, improving the assembly efficiency. On the other hand, it also improves the consistency of the rotational damping feel of the micro camera and enhances the user experience.

[0015] In addition, this damping rotation structure is also provided with a rotating shaft cover, which is fixedly connected to the rotating shaft by screws. By setting the rotating shaft cover, it can not only prevent the rotating shaft from disengaging from the rotating shaft bracket during rotation, but also prevent it from rotating in other directions except the rotation direction.

[0016] Furthermore, the wave gear buckle is an elastic wave gear buckle. The elastic wave gear buckle is arranged at the end of the rotating shaft, with one end fixedly connected to the rotating shaft and the other end set to be suspended. Utilizing the elasticity of the wave gear buckle and the property that one end is fixed and the other end is suspended, when it rubs against the wave teeth, the suspended end can generate elastic deformation, providing frictional force for the rotation between the rotating shafts and generating a damping effect.

[0017] In addition, the number of the wave gear buckles is set to be at least one, and the number of the wave gear buckles can be increased according to the required damping magnitude, so as to increase the friction force between the rotating shaft and the rotating shaft bracket during rotation.

[0018] Moreover, the wave teeth are continuously and evenly distributed on the inner circumferential surface of the rotating shaft bracket, so as to realize the 360° rotation of the rotating shaft, and can stay between any two wave teeth, so as to realize any staying angle of the camera module.

[0023] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0024] The damping rotation structure is arranged in the micro camera and is used to realize the rotation of the camera module and provide damping and friction force for it during rotation.

[0025] As Figure 1 、 2 shown, the damping rotation structure of the micro camera includes a rotating shaft 10, a camera module 20, a rotating shaft bracket 30 and a rotating shaft cover 40.

[0026] As Figure 3 shown, the inside of the rotating shaft 10 is a hollow structure, providing an installation space for the camera module 20. An opening 11 for the camera module 20 to expose is formed on the side wall of the rotating shaft 10. In addition, a plurality of installation positions 12 are arranged on the outer side wall of the end of the rotating shaft 10. Wave gear buckles 13 are correspondingly installed in the installation positions 12. In this embodiment, the number of the installation positions 12 is two, and one wave gear buckle 13 is correspondingly installed in each installation position 12. A certain distance is arranged between the two installation positions 12.

[0027] One end of the wave gear buckle 13 is fixedly connected to the installation position 12, and the other end is set to be suspended, so that the wave gear buckle 13 can be suspended. In addition, the wave gear buckle 13 is an elastic wave gear buckle 13.

[0028] The camera assembly 20 is arranged in the hollow structure of the rotating shaft 10, and the camera therein can be exposed from the opening 11 for recording the external scene.

[0029] As Figure 4 As shown, the rotating shaft bracket 30 includes a fixing plate 31 and a bracket ring 32. The fixing plate 31 can be connected to the point to be fixed of the micro camera, so that the micro camera is fixed (such as on a desktop, in a vehicle, etc.). One side of the bracket ring 32 is fixedly connected to the fixing plate 31. The inner side thereof is hollow, and evenly and continuously distributed wave teeth 33 are arranged on the inner side wall.

[0030] The end of the wave gear buckle 13 arranged on the rotating shaft 10 extends into the bracket ring 32, the wave gear buckle 13 contacts the wave teeth 33, and the rotating shaft 10 is rotatably connected to the bracket ring 32.

[0031] The rotating shaft cover 40 is installed at the port at the end of the rotating shaft 10 and is fixedly connected to the port by screws.

[0032] The rotation principle of the damping rotation structure of the micro camera is as follows: when it is necessary to adjust the shooting angle of the camera, rotate the rotating shaft 10. After the wave gear buckle 13 contacts the wave teeth 33, the wave gear buckle 13 undergoes elastic deformation. Then, the contact surface between the wave gear buckle 13 and the wave teeth 33 slides. The wave gear buckle 13 undergoes the above friction and contact processes with multiple consecutive and identical wave teeth 33 during the rotation of the rotating shaft 10, and the frictional force between the two forms a damping effect; when the rotation of the rotating shaft 10 stops, the wave gear buckle 13 stays between two adjacent wave teeth 33, so that the camera maintains the current rotation angle.

[0033] In the damping rotation structure of the micro camera according to the above embodiments, it includes a rotating shaft, a camera assembly, and a rotating shaft bracket. The inside of the rotating shaft is a hollow structure, the camera assembly is arranged inside the hollow structure, and the rotating shaft bracket is rotatably connected to the rotating shaft. Among them, at least one wave gear buckle is arranged on the rotating shaft, and several wave teeth are arranged inside the rotating shaft bracket, and the wave gear buckle is clamped between the wave teeth. Based on this damping rotation structure, the angle adjustment of the camera assembly is realized through the rotational connection between the rotating shaft and the rotating shaft bracket. In this rotational connection, the rotational damping effect of the structure is realized by the collision and friction between the wave gear buckle on the rotating shaft and the wave teeth on the rotating shaft bracket. During rotation, the wave gear buckle and the wave teeth continuously contact and collide. The wave gear buckle undergoes elastic deformation during each collision and there is a frictional effect with the top of the wave teeth. After stopping rotation, the buckle stays at the middle position between two wave teeth to maintain the current rotation angle. Therefore, this damping rotation structure realizes the rotational damping effect only through the elastic deformation of the rotating shaft structure and the internal structure shape of the rotating shaft bracket without using any damping materials.

[0034] Therefore, this damping rotation structure not only reduces the use of rubber parts, lowers the product cost, and protects the environment, but also reduces the assembly steps and assembly difficulty of the micro camera, improving the assembly efficiency. On the other hand, it also improves the consistency of the rotational damping feel of the micro camera, enhancing the user experience.

[0035] In addition, this damping rotation structure is also provided with a rotating shaft cover, which is fixedly connected to the rotating shaft by screws. By setting the rotating shaft cover, it can not only prevent the rotating shaft from disengaging from the rotating shaft bracket during rotation, but also prevent it from rotating in other directions except the rotation direction.

[0036] Furthermore, the wave gear buckle is an elastic wave gear buckle. This elastic wave gear buckle is arranged at the end of the rotating shaft, with one end fixedly connected to the rotating shaft and the other end suspended. Utilizing the elasticity of the wave gear buckle and the property that one end is fixed and the other end is suspended, when it rubs against the wave teeth, the suspended end can produce elastic deformation, providing frictional force for the rotation between the rotating shafts and generating a damping effect.

[0037] In addition, the number of the wave gear buckles is set to at least one, and the number of wave gear buckles can be increased according to the required damping magnitude, thereby increasing the frictional force between the rotating shaft and the rotating shaft bracket during rotation.

[0038] Moreover, the wave teeth are continuously and evenly distributed on the inner circumferential surface of the rotating shaft bracket, enabling 360° rotation of the rotating shaft and being able to stay between any two wave teeth, realizing any staying angle of the camera assembly.

[0039] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application also intends to include these modifications and variations.
