Description

Technical Field

[0001] This utility model relates to the field of security monitoring equipment technology, and in particular to a wall-mounted camera angle adjustable mounting bracket. Background Technology

[0002] In the field of security monitoring, wall-mounted cameras have become the mainstream choice due to their convenient installation and wide range of applications. The performance of their mounting base directly affects the camera's observation range and stability.

[0003] Currently, common fixed mounting brackets only offer a single installation angle. Once installed, the camera's viewing direction is fixed and cannot be adjusted according to actual usage needs, resulting in blind spots. To address this issue, some adjustable mounting brackets have emerged on the market, such as those using ball joints or manual knob locking mechanisms. However, ball joint structures are prone to shifting due to vibration after adjustment, resulting in insufficient stability; while manual adjustment is inconvenient to operate and difficult to achieve precise control, especially in scenarios where the installation position is high or frequent adjustments are required, significantly reducing their practicality.

[0004] Therefore, there is an urgent need for a wall-mounted camera mount that can achieve electric and precise adjustment. Utility Model Content

[0005] To overcome the inconvenience of adjusting the angle of existing wall-mounted camera mounts, this utility model provides a wall-mounted camera angle-adjustable mount.

[0006] An adjustable wall-mounted camera mounting bracket includes a fixing plate, mounting rings, a support base, a mounting base, a connecting shaft, a controller, a horizontal rotation component, and a tilting rotation component. The fixing plate is a square plate structure with mounting holes through its four corner areas. A mounting ring is coaxially fixed to the top opening of each mounting hole. The support base is horizontally rotatably connected to the top center of the fixing plate. The support base has an overall U-shaped groove structure. The connecting shaft is rotatably connected to the support base, and the mounting base is fixedly connected to the connecting shaft. The controller is installed on the front top of the fixing plate. The fixing plate has a horizontal rotation component, and the support base has a tilting rotation component.

[0007] Furthermore, the inclined rotation component includes a servo motor, a worm gear, and a worm wheel. The servo motor is mounted on a U-shaped groove in the support base. The worm gear is fixedly connected to the output shaft of the servo motor, and the worm wheel is fixedly connected to the middle of the connecting shaft. The worm wheel and the worm gear mesh with each other. The servo motor is electrically connected to the controller through wires.

[0008] Furthermore, the horizontal rotation assembly includes a gear ring, a second servo motor, a spur gear, and a protective shell. The second servo motor is installed inside the rear side of the fixed plate. The output shaft of the second servo motor extends through to the top end face of the fixed plate. A spur gear is fixedly connected to the top of the output shaft of the second servo motor. A gear ring is fixedly connected to the lower outer side of the support base. The gear ring and the spur gear mesh with each other. A protective shell is fixedly connected to the top of the fixed plate at the position outside the support base. Both the gear ring and the spur gear are completely housed in the inner cavity of the protective shell. The second servo motor is electrically connected to the controller through wires.

[0009] Furthermore, the mounting base is provided with multiple positioning holes spaced apart.

[0010] Furthermore, it also includes a sliding frame, a limiting cylinder, a clamping plate, and a return spring. Sliding grooves are symmetrically opened on both sides of the fixed plate. A sliding frame is slidably connected between the two sliding grooves on one side and between the two sliding grooves on the other side. A limiting cylinder is fixedly connected to both ends of the bottom of the sliding frame. A clamping plate is slidably connected inside the limiting cylinder. A return spring is connected between the top of the clamping plate and the inside of the limiting cylinder. The clamping plate and the mounting ring on the corresponding side are aligned with each other and form a snap-fit ​​engagement.

[0011] Furthermore, it also includes a cushioning pad, with the cushioning pad glued to the middle of the bottom of the fixing plate.

[0012] The beneficial effects of this utility model are as follows: 1. By independently setting the horizontal rotation component and the tilting rotation component, the mounting base can be adjusted to rotate horizontally and tilt forward and backward respectively. This structure enables the camera mounted on it to have a composite adjustment capability, which can be flexibly and accurately adjusted to the best observation angle according to actual monitoring needs, effectively expanding the monitoring coverage.

[0013] 2. The gear ring and spur gear of the horizontal rotation component are placed inside the protective shell, which effectively isolates dust and foreign objects and ensures meshing accuracy; the inclined rotation component adopts worm gear transmission, which has stable transmission efficiency. The combination of the two makes the camera stable after adjustment, avoids uncontrolled displacement, and improves the continuity of monitoring.

[0014] 3. The sliding frame drives the limiting cylinder and the clamping plate to move along the slide groove. After the bolt is installed, the return spring drives the clamping plate to cover the installation ring and the bolt head. This structure can prevent the bolt from being loosened by external force or maliciously tightened, while hiding the bolt and improving the safety and durability of the device after installation.

Detailed Implementation

[0021] Example: A wall-mounted camera angle-adjustable mounting bracket, such as... Figures 1-4 As shown, the device includes a fixed plate 1, mounting rings 2, a support base 3, a mounting base 4, a connecting shaft 5, a controller 13, a buffer pad 18, a horizontal rotation assembly, and a tilting rotation assembly. The fixed plate 1 is a square plate structure with mounting holes through its four corners. Mounting rings 2 are coaxially fixed to the top opening of each mounting hole for bolts to pass through, achieving a rigid connection between the device and the wall. A support base 3 is horizontally rotatably connected to the top center of the fixed plate 1 via a bearing. The support base 3 has a U-shaped groove structure, and a connecting shaft 5 is rotatably connected to the support base 3. A mounting base 4 is fixedly connected to the connecting shaft 5. The mounting base 4 is used to support and fix the camera. The rotating engagement of the base 3 allows the mounting base 4 to adjust its tilt angle forward and backward. The horizontal rotation of the support base 3 and the fixing plate 1 allows the mounting base 4 to adjust its direction in the horizontal direction. A controller 13 is mounted on the top front side of the fixing plate 1 via screws. The fixing plate 1 has a horizontal rotation component, and the support base 3 has a tilt rotation component. The mounting base 4 has multiple positioning holes spaced apart, which can be engaged with screws, bolts, and other mounting components to achieve a detachable and fixed connection between the camera and the mounting base 4. A buffer pad 18 is glued to the bottom center of the fixing plate 1. When the fixing plate 1 is installed on the wall, the buffer pad 18 fills the small gap between the fixing plate 1 and the wall, improving the fit.

[0022] like Figure 4As shown, the tilting assembly includes a servo motor 6, a worm gear 7, and a worm wheel 8. The servo motor 6 is mounted on the U-shaped groove in the support base 3 by screws. The worm gear 7 is keyed to the output shaft of the servo motor 6. The worm wheel 8 is fixedly connected to the middle of the connecting shaft 5. The worm wheel 8 and the worm gear 7 mesh with each other. The servo motor 6 is electrically connected to the controller 13 through wires. This structure utilizes the self-locking characteristic of the transmission between the worm gear 7 and the worm wheel 8 to keep the mounting base 4 and the camera stably in the adjusted tilt position, avoiding uncontrolled rotation.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the horizontal rotation assembly includes a gear ring 9, a second servo motor 10, a spur gear 11, and a protective shell 12. The second servo motor 10 is installed inside the rear side of the fixed plate 1 by screws. The output shaft of the second servo motor 10 is set vertically and extends through to the top end face of the fixed plate 1. The top of the output shaft of the second servo motor 10 is fixedly connected to the spur gear 11. The gear ring 9 is fixedly connected to the lower outer side of the support base 3. The gear ring 9 and the spur gear 11 mesh with each other. The protective shell 12 is fixedly connected to the top of the fixed plate 1 at the position outside the support base 3. The gear ring 9 and the spur gear 11 are completely housed in the inner cavity of the protective shell 12. The protective shell 12 can effectively isolate external dust, moisture, and foreign objects from intrusion, ensuring the meshing accuracy and transmission stability of the spur gear 11 and the gear ring 9. The second servo motor 10 is electrically connected to the controller 13 through wires.

[0024] like Figures 1-5 As shown, it also includes a sliding frame 14, a limiting cylinder 15, a clamping plate 16, and a return spring 17. The front and rear side walls of the fixed plate 1 are symmetrically provided with sliding grooves 1401. The two sliding grooves 1401 on the left side and the two sliding grooves 1401 on the right side are horizontally slidably connected to the sliding frame 14. The front and rear ends of the bottom of the sliding frame 14 are welded with limiting cylinders 15. The clamping plate 16 is vertically slidably connected inside the limiting cylinder 15. The top of the clamping plate 16 and the inside of the limiting cylinder 15 are connected to the return spring 17. In the natural state, the elastic force of the return spring 17 causes the bottom end of the clamping plate 16 to extend out of the limiting cylinder 15, and the clamping plate 16 and the mounting ring 2 on the corresponding side are vertically aligned and form a snap-fit ​​engagement.

[0025] When using this device, first, the camera is fixedly assembled on the mounting base 4 by screwing it into the positioning hole of the mounting base 4. Then, threaded slots are pre-cut on the wall at the positions corresponding to the mounting holes of the fixing plate 1. Before installation, push the clamping plate 16 upward to compress the return spring 17 so that the bottom end of the clamping plate 16 retracts into the limiting cylinder 15. Pull the sliding brackets 14 on both sides outward along the slide groove 1401 to move the limiting cylinder 15 and the clamping plate 16 to the outside of the mounting hole. Release the clamping plate 16 to reset it. Insert the fixing bolt into the mounting ring 2 and the mounting hole, screw it into the pre-set threaded slot on the wall and tighten it to complete the rigid fixation of the fixing plate 1 to the wall. Finally, push the clamping plate 16 upward again to push the sliding bracket 14 inward until the clamping plate 16 is directly above the bolt. After releasing the clamping plate 16, the return spring 17 drives the clamping plate 16 to move downward so that the clamping plate 16 covers the mounting ring 2 and the bolt head, forming a limit to prevent the bolt from loosening or being maliciously tightened, thus improving installation safety.

[0026] When the horizontal orientation of the camera needs to be adjusted, the controller 13 sends a drive signal to the second servo motor 10. The output shaft of the second servo motor 10 drives the spur gear 11 to rotate. The spur gear 11, through meshing with the gear ring 9, drives the support base 3 to rotate horizontally around the top center of the fixed plate 1. This, in turn, drives the mounting base 4 and the camera to rotate synchronously through the connecting shaft 5 until the target orientation is achieved. The controller 13 then controls the second servo motor 10 to stop. When the front and rear tilt angle of the camera needs to be adjusted, the controller 13 sends a drive signal to the first servo motor 6. The output shaft of the first servo motor 6 drives the worm gear 7 to rotate. The worm gear 7, through meshing with the worm wheel 8, drives the connecting shaft 5 to rotate around the shaft hole of the support base 3. The connecting shaft 5 synchronously drives the mounting base 4 and the camera to achieve the front and rear tilt angle adjustment. After the adjustment is completed, the first servo motor 6 stops, and the current angle is maintained by utilizing the self-locking characteristics of the worm gear 7 and the worm wheel 8.
