[0002] Coaxial dual-mode transmission refers to a technology that uses only a single coaxial cable to simultaneously power the vehicle-mounted camera and transmit video data in two different formats. This requires only one cable instead of two separate wiring harnesses, significantly reducing cable weight and installation complexity. Currently, existing vehicle-mounted cameras require fine-tuning of the camera's angle after installation to ensure it's positioned directly in front of the vehicle. Furthermore, existing cameras lack the ability to continuously adjust horizontally or vertically, resulting in a limited adjustable range.

[0004] The cited patent reveals the aforementioned problems in the existing technology, therefore we need to propose a coaxial dual-mode transmission vehicle camera. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model utilizes a combination of a base, a central cylinder, an assembly cylinder, a mounting bracket, a limiting sleeve, an elastic locking assembly, and a fixing and anti-loosening assembly. After installation, pressing the assembly cylinder compresses the compression spring, causing the assembly cylinder to move along the limiting ring via the limiting sleeve.

This improves the smoothness of adjustment. After completion, releasing the assembly cylinder allows the compression spring to engage and lock the locking toothed ring with the fixing toothed ring. Rotating the adjusting screw causes the internal thread adjusting sleeve to move along the limiting guide rod via the limiting plate, supporting and fixing the assembly cylinder and base. This effectively prevents the assembly cylinder from loosening due to vibration, ensuring structural stability. Furthermore, rotating the adjusting screw allows for adjustment of the vehicle camera body on the mounting bracket, further improving the precision and convenience of adjustment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides: a coaxial dual-mode transmission vehicle camera, including a base 1, a central cylinder 3 and an assembly cylinder 6 installed at the top center of the base 1; a limiting ring 2 is connected to the top of the base 1 outside the central cylinder 3, and a limiting sleeve 11 that cooperates with the limiting ring 2 is provided at the bottom of the limiting ring 2; an elastic locking component that cooperates with the central cylinder 3 is provided on the inner wall of the assembly cylinder 6; an assembly groove 15 is opened at the top of the inner cavity of the assembly cylinder 6, and a fixing and anti-loosening component that locks and fixes the adjusted position of the assembly cylinder 6 is provided inside the assembly groove 15; a mounting bracket 7 is installed on the top of the assembly cylinder 6, and the vehicle camera body 9 is movably installed on the mounting bracket 7 through an adjusting screw 8.

[0023] It is worth noting that, through the coordinated arrangement of the base 1, center cylinder 3, assembly cylinder 6, mounting bracket 7, limiting sleeve 11, elastic locking component, and fixed anti-loosening component structure, the installed vehicle camera body can be easily rotated and adjusted. It can stably achieve multi-level adjustment and locking effects and can adjust the lateral position. At the same time, it further improves the stability and reliability of the structure.

[0024] An elastic locking assembly includes a fixed toothed ring 4 connected to the outer surface of the central cylinder 3 and a connecting frame 12 connected to the inner wall of the assembly cylinder 6. A locking toothed ring 13 is connected to the surface of the connecting frame 12, and the locking toothed ring 13 cooperates with the fixed toothed ring 4. A positioning post 14 is connected to the center of the top of the inner wall of the assembly cylinder 6. A compression spring 5 is installed inside the central cylinder 3, and the top of the compression spring 5 is sleeved on the outer surface of the positioning post 14.

[0025] Specifically, the fixed gear ring 4 works with the locking gear ring 13 to achieve the effect of locking after adjustment, the compression spring 5 acts on the assembly cylinder 6 to keep the locking gear ring 13 engaged with the fixed gear ring 4, thereby improving the locking stability of the structure, and the positioning post 14 is a structure for positioning the compression spring 5 to prevent it from falling off.

[0026] By adopting a coaxial design between the central cylinder 3 and the assembly cylinder 6, and supplemented by a compression spring 5 and a positioning column 14, automatic centering and buffering during the assembly process are ensured. This also allows the camera to have a certain axial extension and retraction adjustment space, making it convenient to rotate and adjust the camera.

[0027] The fixing and anti-loosening component includes: an adjusting screw 17 movably installed on the inner wall of the assembly groove 15, and an internal thread adjusting sleeve 20 threaded to the bottom end of the adjusting screw 17; wherein, the bottom end of the internal thread adjusting sleeve 20 is connected to a locking block 19, and the surface of the adjusting screw 17 is connected to a positioning plate 18.

[0028] The adjusting screw 17 is used to extend and retract the internal thread adjusting sleeve 20, and to support and fix the assembly sleeve 6 and the base 1, so that the bottom of the locking block 19 is pressed against the surface of the base 1, ensuring that the vehicle camera will not be loosened by vibration or pressure after rotation adjustment.

[0029] The surface of the positioning plate 18 is rotatably connected to the inner wall of the assembly groove 15, and the two sides of the adjusting screw 17 are connected to the top of the inner wall of the assembly cylinder 6 via limit guide rods 16. Limit plates 21 are provided on both sides of the locking block 19, and the limit plates 21 are slidably connected to the surface of the limit guide rods 16. The surface of the internal thread adjusting sleeve 20 is fitted with an anti-loosening spring 22.

[0030] In addition, the positioning plate 18 cooperates with the assembly groove 15 to position the adjusting screw 17 during installation, so that the adjusting screw 17 can rotate within the inner wall of the assembly groove 15. The limiting plate 21 cooperates with the limiting guide rod 16 to ensure the stability of the locking block 19 during movement, prevent deviation, and ensure the stability of the structure. The anti-loosening spring 22 prevents the adjusting screw 17 from loosening, which would cause the locking block 19 to lose its supporting and fixing effect.

[0031] The adjusting screw 8 is rotatably mounted on the inner wall of the mounting bracket 7, and the vehicle camera body 9 is slidably connected to the surface of the mounting bracket 7 through the adjusting screw 8. Fixing holes 10 are distributed on the surface of the base 1.

[0032] Furthermore, the surface of the adjusting screw 8 is provided with a movable block, which can be detachably snapped onto the vehicle camera body 9, or connected to the fixing screw of the vehicle camera body 9. The adjusting screw 8 is equipped with a self-locking structure to prevent loosening. Connecting the adjusting screw 8 allows for fine adjustment of the lateral position of the coaxial dual-mode transmission vehicle camera. Combined with the elastic locking component, it can meet the diverse viewing angle requirements in complex vehicle environments. The fixing holes 10 are the structure for mounting and fixing the base 1. The base 1 can be adapted to various mounting surfaces through the distributed fixing holes 10. The combination of the limiting ring 2 and the limiting sleeve 11 enhances the overall structure's impact and torsional resistance.

[0033] The synergistic action of the elastic locking assembly and the fixed anti-loosening assembly achieves multiple locking of the assembly cylinder 6 and the camera module. The engagement of the fixed gear ring 4 and the locking gear ring 13 in the elastic locking assembly provides initial radial locking force, effectively preventing deflection. The fixed anti-loosening assembly, through a combination of threaded drive and spring compression, further applies axial locking force. This dual protection prevents loosening or displacement caused by vehicle vibration, greatly improving the stability and reliability of the equipment.

[0034] After installation, the compression spring 5 is compressed by pressing the assembly cylinder 6, and the assembly cylinder 6 moves along the limiting ring 2 through the limiting sleeve 11. This releases the locking toothed ring 13 on the connecting frame 12 from the fixing toothed ring 4 on the surface of the central cylinder 3, allowing the assembly cylinder 6, which is equipped with a coaxial dual-mode transmission vehicle camera, to be rotated and adjusted, further improving the smoothness of the adjustment. After completion, the assembly cylinder 6 is released, allowing the compression spring 5 to act, engaging and locking the locking toothed ring 13 with the fixing toothed ring 4. In conjunction with rotating the adjusting screw 17, the internal thread adjusting sleeve 20 moves along the limiting guide rod 16 through the limiting plate 21, supporting and fixing the assembly cylinder 6 and the base 1. This effectively prevents the assembly cylinder 6 from loosening due to vibration, ensuring the stability of the structure. The vehicle camera body 9 can be adjusted on the mounting frame 7 by rotating the adjusting screw 8, further improving the accuracy and convenience of the adjustment.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
