Description

A camera mounting structure Technical Field

[0001] This utility model relates to the field of automated parking system accessories, and in particular to a camera mounting structure. Background Technology

[0002] License plate recognition cameras, also known as automatic license plate recognition systems or license plate identification systems, are devices that use optical character recognition technology, image processing technology, and machine learning algorithms to identify and read vehicle license plate information. These cameras are typically installed at traffic monitoring points, parking lot entrances, or other locations where vehicle management is required.

[0003] Chinese Patent Publication No. CN221705036U, published on 20240913, discloses a license plate recognition camera mounting mechanism, including a mounting column and a base. A lighting lamp and a display screen are mounted on one side of the mounting column. A fixing seat is mounted on the top of the mounting column, and a fixing rod is mounted on the top of the fixing seat. A drive rod is vertically mounted inside the fixing rod, and a connecting ball is mounted on the top of the fixing rod. One end of the drive rod passes through the bottom of the connecting ball and is inside the connecting ball. A mounting groove is provided laterally inside the connecting ball.

[0004] Existing camera mounting structures mostly connect the camera to the mounting post by using a snap-fit ​​ball joint and a ferrule. The ferrule and ball joint are then fixed by the cooperation of a drive rod, wedge block, threaded rod, threaded sleeve, and two sets of locking blocks. In practice, the position of the threaded rod is crucial to the stability of the connection between the ferrule and the ball joint. However, the thread engagement alone cannot guarantee the stability of the threaded rod's position. Therefore, there is an urgent need to propose a corresponding camera mounting structure to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a camera mounting structure to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A camera mounting structure includes a sleeve and a ball that engage with each other. The outer walls of the ball and the sleeve are respectively fixedly connected to a mounting bracket one and a mounting bracket two. A bushing is fixedly connected to the outer wall of the sleeve. A positioning rod is screwed onto the inner wall of the bushing, and the open end of the positioning rod abuts against the outer wall of the ball. A pressure frame and an elastic component for maintaining the position of the pressure frame are integrated on the outer side of the bushing.

[0008] Preferably, the front end face of the bushing is fixedly connected to two sets of symmetrically distributed card holders, and each set of card holders has a card slot in the middle of its front end face.

[0009] Preferably, the elastic component includes a slide rod fixedly connected to the pressure frame, a rotating sleeve sleeved on the outer side of the slide rod, the outer wall of the rotating sleeve being rotatably connected to the outer wall of the bushing via a rotating shaft, and a spring being fixedly connected between the bottom of the slide rod and the inner wall of the rotating sleeve.

[0010] Preferably, the slide bar and the pressure frame are integrally formed, and the slide bar and the pressure frame form a U-shaped structure.

[0011] Preferably, a limiting piece is fixedly connected to the top of the bushing.

[0012] Preferably, a handle is fixedly connected to the top of the pressure frame, and a rubber pad is fixedly connected to the bottom of the pressure frame.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, mounting bracket one and mounting bracket two are fixed to the camera and support column respectively. The engagement characteristics of the ball and the sleeve can expand the adjustable range of the camera. After the camera is adjusted to a suitable angle, the positioning rod is rotated to engage with the inner surface of the bushing. The position of the ball and the camera is locked by the contact friction between the positioning rod and the outer surface of the ball. Then, the pressure bracket is pulled by the lifting ring, and the sliding rod and the rotating sleeve slide together, and the spring is stretched. Then, the pressure bracket is rotated to make it move in conjunction with the rotating sleeve until the pressure bracket is above the top of the positioning rod. The pressure bracket is released to overlap the top of the positioning rod, thereby providing a vertical constraint force for the positioning rod. This constraint force can limit the loosening of the positioning rod, thereby further improving the stability of the camera mounting structure.

[0015] 2. In this application, after the pressure frame is deflected to the top of the positioning rod, the pressure frame is released to engage with the slot on the card seat. This does not affect the pressure frame's ability to provide constraint force to the positioning rod, while limiting the vertical position of the pressure frame itself, preventing the pressure frame from sliding, and ensuring that it is always engaged with the outside of the positioning rod, thereby guaranteeing the constraint effect of the pressure frame on the positioning rod.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4. This utility model provides a technical solution:

[0024] A camera mounting structure includes a sleeve 1 and a ball 2 that are engaged and connected. The outer walls of the ball 2 and the sleeve 1 are respectively fixedly connected to a mounting bracket 3 and a mounting bracket 4. The outer wall of the sleeve 1 is fixedly connected to a bushing 5. The inner wall of the bushing 5 is screwed to a positioning rod 6, and the open end of the positioning rod 6 abuts against the outer wall of the ball 2. The outer side of the bushing 5 is integrated with a pressure frame 9 and an elastic component for maintaining the position of the pressure frame 9.

[0025] Mounting bracket 3 and mounting bracket 4 are fixed to the camera and support column respectively. The engagement characteristics of ball bearing 2 and sleeve 1 can expand the adjustable range of the camera. After the camera is adjusted to a suitable angle, the positioning rod 6 is rotated to engage with the inner wall of the bushing 5. The position of ball bearing 2 and camera is locked by the contact friction between the positioning rod 6 and the outer wall of ball bearing 2. Then, the lifting ring pulls the pressure bracket 9, the sliding rod 11 and the rotating sleeve 8 slide together, and the spring 13 is stretched. Then, the pressure bracket 9 is rotated to make it rotate the sleeve 8 together until the pressure bracket 9 is above the top of the positioning rod 6. The pressure bracket 9 is released to overlap the top of the positioning rod 6, thereby providing a vertical constraint force for the positioning rod 6. This constraint force can limit the loosening of the positioning rod 6, thereby further improving the stability of the camera mounting structure.

[0026] Specifically, as shown in Figures 2 and 4, two sets of symmetrically distributed card holders 7 are fixedly connected to the front end face of the liner 5. Each set of card holders 7 has a slot in the middle of its front end face. After the pressure frame 9 is deflected to the top of the positioning rod 6, the pressure frame 9 is released to engage with the slot on the card holder 7. This does not affect the pressure frame 9's constraint force on the positioning rod 6, while limiting the vertical position of the pressure frame 9 itself and preventing the pressure frame 9 from sliding. This ensures that the pressure frame 9 is always engaged with the outside of the positioning rod 6, thereby guaranteeing the constraint effect of the pressure frame 9 on the positioning rod 6.

[0027] Specifically, as shown in Figures 2 and 3, the elastic component includes a slide rod 11 fixedly connected to the pressure frame 9. A rotating sleeve 8 is sleeved on the outer side of the slide rod 11. The outer wall of the rotating sleeve 8 is rotatably connected to the outer wall of the bushing 5 through a rotating shaft. A spring 13 is fixedly connected between the bottom of the slide rod 11 and the inner wall of the rotating sleeve 8. When the pressure frame 9 is pulled by the lifting ring, the slide rod 11 and the rotating sleeve 8 slide together, and the spring 13 is stretched. Then, the pressure frame 9 is rotated to make it rotate the sleeve 8 together until the pressure frame 9 is above the top of the positioning rod 6. The pressure frame 9 is then released to overlap the top of the positioning rod 6, thereby providing a vertical constraint force for the positioning rod 6. The slide rod 11 and the pressure frame 9 are integrally formed, and the slide rod 11 and the pressure frame 9 form a U-shaped structure, which facilitates the connection between the pressure frame 9 and the outer side of the bushing 5. A limiting piece 10 is fixedly connected to the top of the bushing 5 to maintain the position of the pressure frame 9 when it is not connected to the positioning rod 6. A handle is fixedly connected to the top of the pressure frame 9, and a rubber pad 12 is fixedly connected to the bottom of the pressure frame 9 to further ensure the stability of the connection between the pressure frame 9 and the positioning rod 6.

[0028] Working principle: Mounting bracket 3 and mounting bracket 4 are fixed to the camera and support column respectively. The engaging characteristics of ball bearing 2 and sleeve 1 expand the adjustable range of the camera. After the camera is adjusted to a suitable angle, the positioning rod 6 is rotated to engage with the inner wall of the bushing 5. The position of ball bearing 2 and camera is locked by the contact friction between the positioning rod 6 and the outer wall of ball bearing 2. Then, the lifting ring pulls the pressure bracket 9, the sliding rod 11 and the rotating sleeve 8 slide together, and the spring 13 is stretched. Then, the pressure bracket 9 is rotated to make it move the rotating sleeve 8 together until the pressure bracket 9 is above the top of the positioning rod 6. Release the pressure bracket 9 so that it overlaps the top of the positioning rod 6, thereby providing a vertical constraint force to the positioning rod 6. This constraint force can limit the loosening of the positioning rod 6, thereby further improving the stability of the camera mounting structure. After deflecting the pressure bracket 9 to the top of the positioning rod 6, release the pressure bracket 9 so that it engages with the slot on the card holder 7. This does not affect the pressure bracket 9's constraint force on the positioning rod 6, while limiting the vertical position of the pressure bracket 9 itself, preventing the pressure bracket 9 from sliding, and keeping it always engaged on the outside of the positioning rod 6, thereby ensuring the constraint effect of the pressure bracket 9 on the positioning rod 6.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
