Description
Technical Field
[0001] This utility model relates to the field of adjustment bracket technology, and in particular to a three-degree-of-freedom camera module adjustment bracket. Background Technology
[0002] To facilitate convenient urban traffic management, road condition information is typically collected. A common method is the installation of traffic monitoring and sensing devices on urban roads. These devices are often mounted on overhead poles or under bridges to collect traffic information throughout the city.
[0003] However, existing brackets for installing surveillance equipment are generally large, and since surveillance equipment is usually installed at high locations, the bulky brackets are inconvenient for installers to carry and install. Furthermore, some brackets have cumbersome adjustment mechanisms and offer only one adjustment direction. If, after installation and use, the angle is found to be unsuitable and fine-tuning is required, it may not be possible to achieve this through the bracket's own adjustment mechanism. Utility Model Content
[0004] To address at least one of the aforementioned technical problems, this utility model proposes a three-degree-of-freedom camera module adjustment bracket. By setting a movable plate that can be adjusted back and forth in the horizontal direction, a horizontal angle adjustment bracket that can be rotated in the horizontal direction, and a pitch angle adjustment bracket that can be rotated in the vertical direction on the bracket mounting plate, the camera module mounted on the pitch angle adjustment bracket can achieve adjustment in three degrees of freedom. The adjustment bracket of this application has a simple and compact structure and a small size, thereby solving the problems of complex structure, large size, and single adjustment direction of traditional brackets.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A three-degree-of-freedom camera module adjustment bracket includes a bracket mounting plate. A movable plate is slidably mounted on the upper part of the bracket mounting plate. An L-shaped horizontal angle adjustment bracket is horizontally rotatable on the upper part of the movable plate via a first rotation limiting component. A pitch angle adjustment bracket for mounting a camera module is vertically rotatable on the vertical plate of the L-shaped horizontal angle adjustment bracket via a second rotation limiting component. There is an installation gap between the pitch angle adjustment bracket and the horizontal angle adjustment bracket to facilitate the vertical rotation of the pitch angle adjustment bracket.
[0007] Preferably, the first rotation limiting assembly includes a first rotation shaft passing through the rear end of the horizontal plate of the movable plate and the L-shaped horizontal angle adjusting frame, a first arc-shaped slide groove disposed at the front end of the horizontal plate with the first rotation shaft as the center, and a plurality of first sliding components that are movably fixed to the movable plate and located within the first arc-shaped slide groove.
[0008] Preferably, the rear end of the horizontal plate is provided with a gourd hole to facilitate the installation of the first rotating shaft. The gourd hole includes a mounting hole and a locking hole that are connected and overlapped. The diameter of the mounting hole is larger than the diameter of the locking hole. The rear end of the vertical plate is provided with a U-shaped shaft hole to facilitate the installation of the pitch angle adjustment frame.
[0009] Preferably, the pitch angle adjustment frame includes a base plate parallel to the horizontal plate and a first side plate and a second side plate spaced apart from each other on both sides of the base plate, parallel to the vertical plate.
[0010] Preferably, the front end of the first side plate is provided with a handle for easy rotation and adjustment of the pitch angle adjustment frame.
[0011] Preferably, the second rotation limiting assembly includes a second rotation shaft passing through the rear end of the vertical plate and the first side plate, a second arc-shaped slide groove disposed at the front end of the vertical plate with the second rotation shaft as the center, and a plurality of second sliding components that are movably fixed to the first side plate and slide within the second arc-shaped slide groove.
[0012] Preferably, the movable plate has sliding grooves on both sides along its length, and a plurality of third sliding components are movably fixed to the bracket mounting plate and located in the sliding grooves.
[0013] Preferably, the first sliding assembly, the second sliding assembly, and the third sliding assembly each include a bolt and a nut adapted to the bolt.
[0014] Preferably, the movable plate is a rectangular plate.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This invention utilizes a horizontally adjustable movable plate, a horizontally rotatable angle adjustment bracket, and a vertically rotatable pitch adjustment bracket on a mounting plate. This allows the camera module mounted on the pitch adjustment bracket to achieve three degrees of freedom of adjustment. The adjustment bracket of this application has a simple and compact structure, is small in size, and is easy to install and carry. Furthermore, after installation, the camera module's viewing angle can be adjusted again from three directions as needed.
[0017] This invention facilitates the rapid installation of the L-shaped horizontal angle adjustment frame with the moving plate and the pitch angle adjustment frame by providing easy-to-install hoist holes and U-shaped shaft holes on the horizontal and vertical plates. This saves the operator's installation time. By setting multiple sets of first sliding components, second sliding components, and third sliding components, not only can the adjustment range in three directions be limited, but the installation firmness between the various sliding parts can also be improved.

[0026] To enable those skilled in the art to better understand the technical solutions in this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments in this utility model, and not all of the embodiments in this utility model.
[0027] Please refer to Figure 1-7 A three-degree-of-freedom camera module adjustment bracket includes a bracket mounting plate 1. A movable plate 2 is slidably mounted on the upper part of the bracket mounting plate 1. An L-shaped horizontal angle adjustment bracket 3 is horizontally rotated on the upper part of the movable plate 2 via a first rotation limiting component. A pitch angle adjustment bracket 4 for mounting a camera module is vertically rotated on the vertical plate 32 of the L-shaped horizontal angle adjustment bracket 3 via a second rotation limiting component. There is an installation gap between the pitch angle adjustment bracket 4 and the horizontal angle adjustment bracket to facilitate the vertical rotation of the pitch angle adjustment bracket 4.
[0028] This embodiment, by setting a movable plate 2 that can be adjusted back and forth in the horizontal direction, a horizontal angle adjustment bracket that can be rotated in the horizontal direction, and a vertical angle adjustment bracket 4 on the bracket mounting plate 1, enables the camera module 5 mounted on the angle adjustment bracket 4 to achieve three degrees of freedom adjustment. The adjustment bracket of this application has a simple and compact structure, small size, and is easy to install and carry. At the same time, after installation, the camera angle of the camera module 5 can be adjusted again from three directions as needed.
[0029] like Figure 3 As shown, sliding grooves 21 are provided on both sides of the movable plate 2 along its length direction, and several third sliding components are movably fixed on the bracket mounting plate 1 at positions corresponding to the sliding grooves 21.
[0030] In this embodiment, the third sliding assembly, as well as the first and second sliding assemblies described below, all include bolts 6 and matching nuts 7. It should be noted that, in this embodiment, several bolt holes 6 are provided on both sides of the bracket mounting plate 1 at positions corresponding to the sliding groove 21. Two sets of bolts 6 and nuts 7 are spaced apart on both sides of the bracket mounting plate 1. The distance between the two sets of bolts 6 is determined according to the required adjustment distance of the moving plate 2. The purpose of providing multiple sets of bolts 6 and nuts 7 is not only to limit the adjustment amount in three directions but also to improve the installation firmness between the various sliding components.
[0031] like Figure 2 and Figure 3 As shown, the first rotation limiting assembly includes a first rotation shaft passing through the rear end of the horizontal plate 31 of the movable plate 2 and the L-shaped horizontal angle adjusting frame 3, a first arc-shaped slide groove 311 disposed at the front end of the horizontal plate 31 with the first rotation shaft as the center, and a plurality of first sliding components that are movably fixed to the movable plate 2 and located in the first arc-shaped slide groove 311.
[0032] The horizontal plate 31 has a gourd hole 312 at its rear end to facilitate the installation of the first rotating shaft. The gourd hole 312 includes a mounting hole 3121 and a locking hole 3122 that are connected and overlapped. The diameter of the mounting hole 3121 is larger than the diameter of the locking hole 3122.
[0033] It is understandable that, in order to ensure that the L-shaped horizontal angle adjusting bracket 3 can rotate horizontally relative to the moving plate 2 around the first rotation, the multiple sets of bolts 6 and nuts 7 movably fixed on the moving plate 2 should be installed within the orthographic projection of the first arc-shaped slide groove 311 onto the moving plate 2. The arrangement and function of the multiple sets of bolts 6 and nuts 7 are the same as described above, and will not be repeated here.
[0034] It should be noted that the aforementioned gourd hole 312 is for quick installation. Specifically, the first rotating shaft is a pin, and generally the diameter of the pin's head is larger than the diameter of the pin rod. The first rotating shaft is fixed to the moving plate 2. During installation, simply place the L-shaped horizontal angle adjusting bracket 3 onto the first rotating shaft through the larger diameter mounting hole 3121, and then push the L-shaped horizontal angle adjusting bracket 3 to rotate and lock it with the first rotating shaft through the locking hole 3122. At this point, tightening the bolts 6 and nuts 7 in the first arc-shaped sliding groove 311 appropriately will achieve the initial fixation of the L-shaped horizontal angle adjusting bracket 3 and the moving plate 2. At this point, it is not necessary to fully tighten the bolts 6; it is sufficient to ensure that there is a certain frictional resistance between the L-shaped horizontal angle adjusting bracket 3 and the moving plate 2 to prevent relative rotation between them.
[0035] In this embodiment, the mounting hole 3121 is a circular hole, and the locking hole 3122 is a U-shaped hole. The opening end of the U-shaped hole is connected to the opening of the circular hole.
[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the pitch angle adjustment frame 4 includes a base plate 41 parallel to the horizontal plate 31, and a first side plate 42 and a second side plate 43 parallel to the vertical plate 32 and spaced apart on both sides of the base plate 41. The second rotation limiting assembly includes a second rotation shaft passing through the rear ends of the vertical plate 32 and the first side plate 42, a second arc-shaped slide groove 321 located at the front end of the vertical plate 32 with the second rotation shaft as the center, and a plurality of second sliding components that are movably fixed to the first side plate 42 and slide within the second arc-shaped slide groove 321.
[0037] It should be noted that in this embodiment, the second rotating shaft is a pin, and the rear end of the vertical plate 32 is provided with a U-shaped shaft hole 322 to facilitate the installation of the pitch angle adjustment bracket 4. The function of the U-shaped shaft hole 322 is the same as that of the gourd hole 312 mentioned above, that is, to facilitate the fixing of the pitch angle adjustment bracket 4 to the L-shaped horizontal angle adjustment bracket 3 with the bolt 6.
[0038] Specifically, during installation, the pin on the first side plate 42 is inserted into the U-shaped shaft hole 322, and then the bolt 6 is passed through the second arc-shaped sliding groove 321 and fixed to the vertical plate 32. Similarly, at this time, it is not necessary to fully tighten the bolt 6; it is only necessary to ensure that there is frictional resistance between the first side plate 42 and the vertical plate 32 to prevent the pitch angle adjustment frame 4 from rotating relative to the L-shaped horizontal angle adjustment frame 3.
[0039] like Figure 6 As shown, in order to facilitate the rotation of the pitch angle adjustment frame 4, the front end of the first side plate 42 in this embodiment is provided with a handle 421 for easy rotation and adjustment of the pitch angle adjustment frame 4.
[0040] It should be noted that in this embodiment, the movable plate 2 is a rectangular plate, and the vertical plate 32 and horizontal plate 31 of the L-shaped horizontal angle adjustment frame 3 are also rectangular plates. The front part of the first side plate 42 is a rectangular plate, and the rear part is a triangular plate with a width smaller than the front part, wherein the apex corner of the triangular plate is rounded. At the same time, the width of the first side plate 42 is smaller than the width of the vertical plate 32. After installation, there is a certain installation gap between the base plate 41 and the horizontal plate 31, which serves as space for the pitch angle adjustment frame 4 to rotate.
[0041] The installation process of this utility model is as follows:
[0042] First, install the camera module 5 in the U-shaped space of the pitch angle adjustment frame 4, insert the pin of the pitch angle adjustment frame 4 into the U-shaped shaft hole 322 of the vertical plate 32 of the L-shaped horizontal angle adjustment frame 3, and tighten the bolt 6 in the second arc-shaped slide groove 321 appropriately to complete the fixation of the pitch angle adjustment frame 4 and the L-shaped horizontal angle adjustment frame 3.
[0043] Then, through the gourd hole 312, the L-shaped horizontal angle adjustment bracket 3 is fitted onto the pin of the moving plate 2, and the bolts 6 are tightened appropriately to complete the fixation between it and the moving plate 2.
[0044] Next, align the sliding groove 21 of the movable plate 2 with the screw hole on the bracket mounting plate 1, and tighten the bolt 6 appropriately to complete the fixation with the bracket mounting plate 1. At this point, the initial installation of the entire adjustment bracket is completed.
[0045] Finally, adjust the front-to-back distance of the movable plate 2 relative to the bracket mounting plate 1, the horizontal rotation angle of the L-shaped horizontal angle adjustment bracket 3 relative to the movable plate 2, and the vertical rotation angle of the pitch angle adjustment bracket 4 relative to the vertical plate 32 as needed. After the adjustment in the three degrees of freedom is completed, tighten all the bolts 6 to complete the final fixing of the adjustment bracket.
[0046] This invention, by setting a movable plate 2 that can be adjusted back and forth in the horizontal direction, a horizontal angle adjustment bracket that can be rotated in the horizontal direction, and a vertical angle adjustment bracket 4 on the bracket mounting plate 1, enables the camera module 5 mounted on the angle adjustment bracket 4 to achieve three degrees of freedom adjustment. The adjustment bracket of this application has a simple and compact structure, small size, and is easy to install and carry. At the same time, after installation, the camera angle of the camera module 5 can be adjusted again from three directions as needed.
[0047] The above description is a specific implementation of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the scope of protection of this application.
