Description

Technical Field

[0001] The utility model relates to the technical field of panoramic images, in particular to a fixing bracket for capturing panoramic images. Background Art

[0002] Informatization and intelligence are increasingly reflected in vehicle driving, providing users with a better driving experience. The panoramic imaging function can provide field of view, eliminate blind spots, and record images.

[0003] Panoramic images are generally stitched together by collecting images from multiple cameras. Most of the cameras are fixed in place because they are installed outside the cockpit. However, the cockpit is also equipped with image collection cameras that are convenient for active recording and viewing of video footage. However, these cameras are often installed using a ball head connection to facilitate angle adjustment. When the vehicle is bumpy and vibrating, they are prone to offset, making it impossible for the camera to capture the entire picture, affecting image collection. In addition, these installation methods are not convenient for adjusting the height, and the position needs to be adjusted frequently during installation to prevent the camera's field of view from being affected by debris placed in the car. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a fixing bracket for panoramic image acquisition.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-6 A fixed bracket for panoramic image acquisition includes a base 1 and a rotating arm 8. The top of the base 1 is fixedly connected to a support sleeve 2, the top of the support sleeve 2 is fixedly connected to a fixed block 5, the top of the fixed block 5 is provided with a rotating shaft 6, the top of the fixed block 5 is rotatably connected to the rotating arm 8 through the rotating shaft 6, the middle of the rotating arm 8 is provided with a hollow groove 11, and the interior of the hollow groove 11 is provided with an adjustment mechanism 12;

[0026] The adjusting mechanism 12 includes a bidirectional screw 13 and a movable block 14. A bidirectional screw 13 is rotatably connected on both sides of the hollow groove 11. One end of the bidirectional screw 13 passes through the rotating arm 8 and is fixedly connected to the handle 17. Two mutually symmetrical movable blocks 14 are threadedly connected to the threads on both sides of the bidirectional screw 13. Sliders 141 are provided on both sides of the two movable blocks 14, and the sliders 141 are slidably connected to the inner wall of the hollow groove 11. The supporting sleeve 2 is a two-stage mechanism, which is convenient for lifting and lowering operations through the rotating block 3. The semicircular structure of the fixed block 5 facilitates the angle adjustment of the rotating arm 8. The adjusting mechanism 12 drives the bidirectional screw 13 to rotate by manually rotating the handle 17, so that the two movable blocks 14 approach or move away from each other in opposite directions, thereby driving the second rotating block 16 to rotate and drive the positioning block 18 to slide up and down along the hollow groove 11, so that the positioning pin 181 can be connected to or disengaged from the positioning groove 7 to lock or unlock the rotating arm 8. When the angle needs to be adjusted, the rotating arm 8 is unlocked for manual adjustment. After the adjustment is completed, the rotating arm 8 is locked so that the position of the rotating arm 8 is fixed and the camera will not be unable to collect images normally due to bumps and vibrations. Compared with the ordinary ball head installation method, it is more stable and will not affect the normal operation of panoramic image acquisition.

[0027] As a technical optimization solution of the present invention, the middle portion of the support sleeve 2 is rotatably connected to a rotating block 3, and the center of the rotating block 3 is fixedly connected to a lifting screw 4. The top of the lifting screw 4 is threadedly connected to the lifting portion of the top of the support sleeve 2, and the bottom of the lifting screw 4 is slidably connected to the fixed portion of the bottom of the support sleeve 2. When the height needs to be adjusted, holding the rotating arm 8 and manually rotating the rotating block 3 will drive the lifting screw 4 to rotate, thereby causing the fixed block 5 to be raised or lowered. Moreover, due to the threaded connection, the fixed block 5 and the rotating arm 8 can maintain a stable connection after the height is adjusted, and there will be no problems such as deviation.

[0028] As a technical optimization solution of the present invention, a suction cup is provided at the bottom of the base 1, and a plurality of positioning grooves 7 are evenly distributed on the outer wall of the top of the fixing block 5. The bottom of the base 1 can be mounted using the suction cup or other methods such as 3M adhesive, depending on the actual installation environment. The positioning grooves 7 are adapted to the positioning pins 181, which facilitate the positioning pins 181 to lock the rotating arm 8.

[0029] As a technical optimization solution of the present invention, the end of the rotating arm 8 is fixedly connected to a mounting bracket 10, and a plurality of screw holes are evenly opened around the mounting bracket 10. The mounting bracket 10 is used to install a panoramic image acquisition camera, and cameras of different specifications can be installed through the screw holes.

[0030] As a technical optimization solution of the present invention, two connecting holes 9 are symmetrically defined at the bottom of the rotating arm 8. Rubber pads 91 are mounted on the inner walls of the two connecting holes 9. The diameter of the rubber pads 91 is smaller than that of the rotating shaft 6. The rubber pads 91 form an interference fit with the rotating shaft 6 and the connecting holes 9, which enhances the friction between the rotating shaft 6 and the connecting holes 9, thereby stabilizing the rotating arm 8. This also prevents the rotating arm 8 from rotating directly to its extreme angle when the adjustment mechanism 12 is unlocked during adjustment of the rotating arm 8, facilitating operation. Furthermore, the rubber pads 91 provide temporary stability in the event that the rotating arm 8 is forgotten to be locked.

[0031] As a technical optimization solution of the present invention, the top of the movable block 14 is rotatably connected to a retractable first rotating block 15. The top of the first rotating block 15 is rotatably connected to the top of the hollow slot 11. The bottom of the movable block 14 is rotatably connected to a second rotating block 16. The first rotating block 15 is retractable, which facilitates the movement of the movable block 14 without locking. The second rotating block 16 cannot be retracted, but it can drive the positioning block 18 to move up and down.

[0032] As a technical optimization solution of the present invention, a positioning block 18 is slidably connected to the bottom of the hollow groove 11. The top of the positioning block 18 is rotatably connected to the bottom of the two second rotating blocks 16. The bottom of the positioning block 18 has an arc-shaped structure and is evenly distributed with three positioning pins 181. When the two movable blocks 14 move, they can drive the second rotating blocks 16 to move, thereby achieving the raising and lowering of the positioning block 18, so that the positioning pins 181 engage or disengage from the positioning groove 7.

[0033] When the present invention is in use, the bottom of the base 1 can be installed by a suction cup or by 3M glue, etc., which can be selected according to the actual installation environment. The panoramic image acquisition camera is installed on the mounting bracket 10 through the screw hole, and the handle 17 is manually rotated to drive the bidirectional screw 13 to rotate, so that the two movable blocks 14 move away from each other in opposite directions. At this time, the second rotating block 16 rotates to drive the positioning block 18 to slide upward along the hollow groove 11 to be stored, so that the positioning pin 181 is disengaged from the positioning groove 7 and the rotating arm 8 is unlocked. At this time, the rotating arm 8 can be rotated to adjust the angle, and the rotating arm 8 can be held and manually adjusted. Rotating the rotating block 3 can drive the lifting screw 4 to rotate, thereby making the fixed block 5 and the rotating arm 8 rise and fall. At this time, due to the interference fit of the rubber pad 91 with the rotating shaft 6 and the connecting hole 9, the friction between the rotating shaft 6 and the connecting hole 9 can be enhanced, which is convenient for stabilizing the rotating arm 8. After the adjustment is completed, the reverse handle 17 is used to drive the bidirectional screw 13 to rotate, so that the two movable blocks 14 approach each other in opposite directions. At this time, the second rotating block 16 rotates to push the positioning block 18 to slide downward along the hollow groove 11, so that the positioning pin 181 can be connected to the positioning groove 7 and then lock the rotating arm 8, and the panoramic image acquisition camera can be used normally for image acquisition.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
