Description

Technical Field

[0001] This invention relates to the field of camera mounting bracket technology, and more specifically to a camera mounting device that facilitates fine-tuning of the angle. Background Technology

[0002] Expanding the field of view of optical equipment requires stitching images from multiple cameras. During stitching, the installation angles of each camera need to be precisely adjusted to ensure that the position, azimuth, pitch, and roll angles meet the requirements.

[0003] Camera equipment used in the field requires a sealed housing to prevent water and dust. When multiple cameras are inside the sealed housing to capture images of different areas, the optical axis angle of each camera cannot be precisely pre-adjusted due to the unpredictable installation position. When installed in the field, it is inconvenient to open the housing for internal fine-tuning.

[0004] In common multi-camera cameras, the camera angles are determined by precisely machining the mounting structure. This is the simplest and easiest method for mass-produced products. However, this method requires the mass production of mounting brackets using specialized molds. Once the mounting brackets are manufactured, the angles are fixed and cannot be adjusted. In actual work, different scenarios often require different field of view angles. When it is not necessary to mass-produce mounting brackets of the same specifications, fine-tuning the angles between the cameras is a time-consuming and laborious task.

[0005] Therefore, a simple and reliable optical axis fine-tuning device is needed to achieve fine-tuning of the optical axis angle of some cameras during on-site installation. Summary of the Invention

[0006] The purpose of this invention is to provide a camera mounting device that facilitates fine-tuning of the angle, thereby solving the problem in the prior art where it is inconvenient to open the housing for fine-tuning of camera devices with multiple cameras inside a sealed housing when installing them in the field.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A camera mounting device for easy fine-tuning of the angle includes a base plate, a horizontal adjustment plate rotatably mounted on the upper side of the base plate along a vertical axis, an azimuth adjustment mechanism for driving the horizontal adjustment plate to rotate on the base plate, a mounting frame mounted on the upper side of the horizontal adjustment plate, a support and fixing plate mounted in the middle of the mounting frame, the support and fixing plate being rotatably connected to the mounting frame along a horizontal axis, and a pitch adjustment mechanism for driving the support and fixing plate to rotate on the base plate. The control ends of both the azimuth adjustment mechanism and the pitch adjustment mechanism are located on the lower side of the base plate.

[0009] A further technical solution is that the orientation adjustment mechanism includes an adjustment gear and an adjustment shaft. The horizontal adjustment plate is a sector gear. The adjustment gear meshes with the sector gear and is connected to it. The adjustment shaft is coaxially connected with the adjustment gear. The lower end of the adjustment shaft is the control end of the orientation adjustment mechanism and is located on the lower side of the base plate.

[0010] A further technical solution is that the sector gear is provided with at least two arc-shaped slots that pass through the upper and lower sides, the arc-shaped slots are arranged concentrically with the sector gear, and a limit rod is provided on the upper side of the base plate within the arc-shaped slots.

[0011] A further technical solution is that the pitch adjustment mechanism includes a worm gear and a worm. A rotating shaft is horizontally arranged in the middle of the mounting frame. The end of the rotating shaft is rotatably connected to the mounting frame. The supporting fixing plate is fixedly connected to the rotating shaft. The worm gear is coaxially mounted on the rotating shaft. The worm is vertically arranged on the upper side of the water-sector gear and is connected to the worm gear drive. The center of the sector gear is provided with a through hole that passes through both the upper and lower sides. The lower end of the worm passes through the through hole and the base plate and is placed on the lower side of the base plate. The lower end of the worm is the control end of the pitch adjustment mechanism.

[0012] A further technical solution is that the mounting frame includes two spaced-apart uprights and a top plate mounted on top of the two uprights. The rotating shaft is located between the two uprights and its two ends are rotatably connected to the two uprights respectively. The upper end of the worm gear is rotatably connected to the top plate.

[0013] A further technical solution includes a locking screw, the upper end of which is rotatably connected to the top plate and the lower end of which is rotatably connected to the bottom plate. A first locking block is threadedly connected to the locking screw at the position corresponding to the upper side of the worm gear 9. A limit hole is provided on the vertical plate, and the first locking block is slidably connected to the limit hole. A soft rubber friction surface is provided on the lower side of the first locking block. An arc-shaped locking hole for the locking screw to pass through is provided on the horizontal adjustment plate. The arc-shaped locking hole is concentric with the sector gear. The opposite sides of the groove wall in the circumferential direction of the arc-shaped locking hole are respectively set as first inclined surfaces that approach each other from top to bottom. A second locking block is threadedly connected to the locking screw at the position of the locking hole. The opposite sides of the lower end of the second locking block are respectively set as second inclined surfaces that match the first inclined surfaces. Both the first and second inclined surfaces are set as friction surfaces.

[0014] A further technical solution is to provide cross grooves or internal hexagonal grooves at the lower ends of the adjusting shaft, worm gear, and locking screw.

[0015] Compared with existing technologies, the advantages of this invention are as follows: By setting up a mounting bracket and a support plate, the camera can be mounted on the support plate. During internal fine-tuning, the orientation adjustment mechanism can control the rotation of the horizontal adjustment plate, thereby controlling the horizontal adjustment of the camera. The tilt adjustment mechanism can control the tilt adjustment of the camera. Since the control ends of both the orientation and tilt adjustment mechanisms are located on the sides of the sealed housing, adjustments can be made through the adjustment holes in the housing when the device is installed inside, without opening the entire housing. Because this device is mainly used for one-time adjustment during installation, it is simpler and more reliable than an electric pan-tilt head, and will not fail due to motor malfunction or power outage, nor will it malfunction due to interference or external vibration.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] Figures 1 to 5 The image shows an embodiment of the present invention.

[0024] Example:

[0025] A camera mounting device for easy angle adjustment includes a base plate 1. A horizontal adjustment plate 2 is rotatably mounted on the upper side of the base plate 1 along a vertical axis. An azimuth adjustment mechanism for driving the rotation of the horizontal adjustment plate 2 is mounted on the base plate 1. A mounting frame 3 is mounted on the upper side of the horizontal adjustment plate 2. A support plate 4 is mounted in the middle of the mounting frame 3. The support plate 4 is rotatably connected to the mounting frame 3 along a horizontal axis. A tilt adjustment mechanism for driving the rotation of the support plate 4 is mounted on the base plate 1. The control ends of both the azimuth adjustment mechanism and the tilt adjustment mechanism are located on the lower side of the base plate 1. By setting the mounting frame 3 and the support plate 4, a camera 21 can be mounted on the support plate 4. During internal fine-tuning, the azimuth adjustment mechanism can control the rotation of the horizontal adjustment plate 2, thereby controlling the horizontal adjustment of the camera 21. The tilt adjustment mechanism can control the tilt adjustment of the camera 21. Since the control ends of the azimuth adjustment mechanism and the pitch adjustment mechanism are both located on the lower side of the base plate 1, the adjustment can be made from the bottom of the housing when the base plate 1 is installed inside the housing, without having to open the entire housing.

[0026] The orientation adjustment mechanism includes an adjusting gear 5 and an adjusting shaft 6. The horizontal adjusting plate 2 is a sector gear. The adjusting gear 5 is meshed and connected to the sector gear. The adjusting shaft 6 is coaxially connected to the adjusting gear 5. The lower end of the adjusting shaft 6 is the control end of the orientation adjustment mechanism and is located on the lower side of the base plate 1. When it is necessary to adjust the horizontal orientation of the camera 21, rotating the adjusting shaft 6 can drive the adjusting gear 5 to rotate, thereby driving the sector gear to rotate in a circle, which in turn drives the supporting fixing plate 4 and the camera 21 mounted on it to adjust the horizontal angle.

[0027] The sector gear has at least two arc-shaped slots 7 that extend through its upper and lower sides. The arc-shaped slots 7 are concentric with the sector gear. A limit rod 8 is provided on the upper side of the base plate 1 within the arc-shaped slots 7. By providing two or more arc-shaped slots 7 and limit rods 8 in cooperation, the sector gear can rotate around the center when driven by the adjusting gear 5, thereby achieving precise adjustment and preventing the sector gear and adjusting gear 5 from disengaging.

[0028] The pitch adjustment mechanism includes a worm gear 9 and a worm 10. A rotating shaft 11 is horizontally arranged in the middle of the mounting frame 3, and the end of the rotating shaft 11 is rotatably connected to the mounting frame 3. The supporting plate 4 is fixedly connected to the rotating shaft 11. The worm gear 9 is coaxially mounted on the rotating shaft 11. The worm 10 is vertically arranged above the water-sector gear and is connected to the worm gear 9 for transmission. The center of the sector gear has a through hole that passes through both the upper and lower sides. The lower end of the worm 10 passes through the through hole and the base plate 1 and is placed on the lower side of the base plate 1. The lower end of the worm 10 is the control end of the pitch adjustment mechanism. When pitch angle adjustment is required, by rotating the worm 10, the worm gear 9 can be engaged. When the worm 10 rotates, the worm gear 9 can drive the rotating shaft 11 and the supporting plate 4 to rotate, thereby realizing the pitch angle adjustment of the camera 21.

[0029] The mounting bracket 3 includes two spaced-apart upright plates 12 and a top plate 13 mounted on top of the two upright plates 12. A rotating shaft 11 is positioned between the two upright plates 12, with both ends rotatably connected to the two upright plates 12 respectively. The upper end of the worm gear 10 is rotatably connected to the top plate 13. Through the cooperation of the two upright plates 12 and the top plate 13, the stability of the mounting plate 4 can be achieved. The two upright plates 12 can provide stable support and rotation for the rotating shaft 11, and the top plate 13 can rotatably fix the upper end of the worm gear 10.

[0030] It also includes a locking screw 14, the upper end of which is rotatably connected to the top plate 13 and the lower end of which is rotatably connected to the bottom plate 1. The locking screw 14 is threadedly connected to a first locking block 15 at the position corresponding to the upper side of the worm gear 9. A limit hole 16 is provided on the vertical plate 12. The first locking block 15 is slidably connected to the limit hole 16. A soft rubber friction surface is provided on the lower side of the first locking block 15. An arc-shaped locking hole 17 for the locking screw 14 to pass through is provided on the horizontal adjustment plate 2. The arc-shaped locking hole 17 is concentric with the sector gear. The opposite sides of the groove wall in the circumferential direction of the arc-shaped locking hole 17 are respectively set as first inclined surfaces 19 that approach each other from top to bottom. The locking screw 14 is threadedly connected to a second locking block 18 at the position of the locking hole. The opposite sides of the lower end of the second locking block 18 are respectively set as second inclined surfaces 20 that match the first inclined surfaces 19. Both the first inclined surfaces 19 and the second inclined surfaces 20 are set as friction surfaces. After the angle adjustment is completed, to prevent the camera 21 from shifting during use, the angle of the camera 21 can be locked by the locking screw 14 in conjunction with the first locking block 15 and the second locking block 18. Specifically, when a fixed angle is needed, the locking screw 14 is rotated to move the first locking block 15 downwards. The limiting hole 16 restricts the movement of the first locking block 15, preventing it from rotating with the locking screw 14. The lower end surface of the locking block 15 is a soft rubber friction surface. When the locking screw rotates and descends, the soft rubber friction surface presses against the worm gear 9 to brake it. By setting the second locking block 18 in conjunction with the arc-shaped locking hole 17, the second locking block 18 can move downwards when the locking screw 14 rotates, pressing against the hole walls on both sides of the arc-shaped locking hole 17 to prevent the horizontal adjustment plate 2 from continuing to rotate. By means of the inclined surfaces on both sides of the second locking block 18, a gap can be left between the two sides of the second locking block 18 and the opposite sides of the arc-shaped locking hole 17 during the upward movement, allowing the horizontal adjusting plate 2 to rotate. During the downward movement, the first inclined surface 19 and the second inclined surface 20 are pressed together to fix the second locking block 18 against the arc-shaped locking hole 17. By means of the friction surface, relative sliding between the second locking block 18 and the arc-shaped locking hole 17 can be prevented.

[0031] The lower ends of the adjusting shaft 6, worm gear 10, and locking screw 14 are all provided with cross grooves or internal hexagonal grooves. By providing cross grooves or internal hexagonal grooves, it is easy to drive the adjusting shaft 6, worm gear 10, and locking screw 14 to rotate using adjusting tools, thereby realizing the adjustment of the camera angle 21.

[0032] A typical application of this device is its installation on the bottom or side of a sealed housing. Adjustment holes are made at the corresponding positions of the adjusting shaft 6, worm gear 10, and locking screw 14 on the sealed housing, and sealing covers are installed thereon. When the device is installed inside the sealed housing, adjustment can be made through the adjustment holes. After adjustment, the device is locked using the locking screw 14, and then the sealing cover is tightened. Adjusting the angle does not require opening the entire housing; the adjustment hole is connected to the sealing cover via a threaded connection. By providing the adjustment holes, the sealing cover can be removed when adjustment is needed, allowing the adjusting shaft 6, worm gear 10, and locking screw 14 to rotate through the adjustment holes. After adjustment, the adjustment holes are sealed with the sealing cover to prevent external water, dust, etc., from entering the housing.

[0033] This device does not include an outer casing; it is generally housed within a sealed housing. The sealed housing is fixed to the device using studs at the mounting connection surface. Adjustment holes are provided at the adjustment ends of the adjusting shaft 6, worm gear 10, and locking screw 14 corresponding to the installation position. The inner wall of the adjustment hole is provided with internal threads and a waterproof rubber ring for installing a sealing cover. The angle can be adjusted when the sealing cover is open, and the sealing cover is waterproof and dustproof when tightened.

[0034] This device can be installed on the bottom plate, side plate, or top plate of the sealed housing as needed.

[0035] The size of this device is determined according to the camera (including sensor and camera) to be installed. When the camera is large, a concave arc-shaped camera support should be set on the support plate 4 at the waist position of the camera. After the camera is fixed, the camera is fixed by cable ties, rubber pads and support to prevent the sensor and camera connection seat from deforming or even being damaged due to long-term stress in a vibration environment. This is not necessary for small-sized cameras.

[0036] Although the invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
