Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted cameras, in particular to a camera rotation fixing structure. Background Art

[0002] The vehicle-mounted camera's ability to present video and audio in real time provides a more scientific basis for the handling and positioning of traffic accidents, fully protecting our property and life safety. It can also monitor the environment inside and outside the vehicle, providing safety protection for vehicle driving.

[0003] At present, most of the cameras for vehicle recording use a single-camera structure. Due to the unreasonable design of the camera's rotating structure and fixing method, the camera is difficult to rotate, and the torque required for rotation cannot be adjusted according to user experience. Or the rotating structure has been used for too long, and there is wear between the contact parts, resulting in excessive matching clearance. The camera shakes severely when the vehicle is driving, affecting the shooting field of view.

[0004] In order to solve the above problems, a camera rotation and fixing structure is proposed in the present application. Utility Model Content

[0005] In response to the problems in the related technology, the utility model provides a camera rotation and fixing structure, which can not only adjust the rotation torque according to the user's feeling, but also avoid the wear of contact parts and camera shaking caused by long-term use, which affects the shooting field of view.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0007] A camera rotation and fixing structure comprises a ball head sleeve, a universal ball head is rotatably connected in the ball head sleeve, a slide groove is provided on the inner wall of the universal ball head, a ball base is slidably connected in the slide groove, a ball body is placed on the bottom wall of the ball base, and the ball body passes through the ball fixing frame and the bottom wall of the universal ball head in sequence and is rotatably connected to the inner wall of the ball head sleeve, a round wire spring is placed in the groove of the ball base, a spring pressure plate is placed on the upper end of the round wire spring, a limiting hole is provided in the middle of the spring pressure plate, a butterfly bolt passes through the limiting hole, and the butterfly bolt passes through the spring pressure plate, the round wire spring, the ball base and the ball fixing frame in sequence and is connected to the universal ball head.

[0008] As a further solution of the utility model, the ball body is evenly distributed on the bottom wall of the ball base in six equal parts.

[0009] As a further solution of the utility model, the ball fixing frame is connected to the ball base through mechanical screws.

[0010] As a further solution of the utility model, the spring pressure plate is slidably connected to a sliding groove on the inner wall of the universal ball head.

[0011] The beneficial effects of the utility model are:

[0012] The utility model uses a ball fixing frame and a ball base to connect and fix the ball body with a mechanical screw, so that it can rotate but not easily fall off. Secondly, the exposed part of the ball body contacts the inner wall of the ball head sleeve, and the ball body uses the elastic force of the round wire spring to always contact the inner wall of the ball head sleeve to maintain a fixed pre-tightening force. The pre-tightening force is generated by feeding the butterfly bolt to push the spring pressure plate to compress the round wire spring to generate elastic force. Due to the effect of the elastic force, the ball body is always in contact with the inner wall of the ball head sleeve and has a fixed pre-tightening force. The size of the pre-tightening force can be determined by the number of turns fed by the butterfly nut, so the rotational torque of the camera can be ensured, which can be adjusted according to customer experience. In addition, when the ball head sleeve is worn, the pre-tightening force of the camera can be ensured to remain unchanged, not shake, and not affect the field of view. At the same time, the universal structure of the ball head can meet the needs of multi-angle video shooting and monitoring, with wide adaptability, simple product assembly, high reliability, simple operation, low cost and strong practicality.
