Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a mounting bracket for a lidar. Background Technology

[0002] LiDAR (Light Detection and Ranging) is a radar system that uses laser beams to detect the position, velocity, and other characteristics of a target. Its working principle involves transmitting a detection signal to the target, then comparing the received signal reflected back from the target with the transmitted signal. After appropriate processing, information about the target, such as its distance, azimuth, altitude, velocity, attitude, and even shape, can be obtained.

[0003] In autonomous driving technology, LiDAR is typically mounted on the vehicle body or frame using a mounting bracket. According to the existing authorized announcement date - CN215986472U, a LiDAR bracket is provided, which includes a steel ball disposed between a fixed plate and a bracket plate. The steel ball is used to adjust the pitch angle of the bracket plate. After adjustment, multiple set screws and multiple fastening bolts are used to fix the bracket plate at that angle, so as to realize the adjustment of the pitch angle of the LiDAR.

[0004] Although the bracket plate can be fixed by multiple set screws and multiple fastening bolts, the fixing process is complicated. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a mounting bracket for lidar, so as to solve the technical problem that existing lidar brackets in the background art have complex operation.

[0006] The present invention provides a mounting bracket for a lidar, including a fixing plate for connecting to a vehicle, a bracket plate for fixing the lidar, at least one rotating joint assembly, and at least one adjusting assembly.

[0007] Both the rotating pair assembly and the adjusting assembly are disposed between the fixed plate and the support plate, such that a gap is formed between the fixed plate and the support plate, allowing the support plate to rotate in the opposite direction around the rotation fulcrum;

[0008] The rotating joint assembly is located on one side of the gap and is used to rotatably connect the fixing plate and the support plate. The adjusting assembly is located on the other side of the gap and is used to adjust the rotation angle between the fixing plate and the support plate.

[0009] Furthermore, the mounting bracket includes two rotating joint components, which are respectively disposed at both ends of one side of the gap.

[0010] Furthermore, a first reference line is constructed along the two rotating joint components as two reference points;

[0011] A second reference line is constructed along the transverse direction of the adjustment component, and the second reference line intersects the middle of the first reference line.

[0012] Furthermore, the rotating pair assembly includes a first rotating shaft and a second rotating shaft that are rotatably connected to each other, and the first rotating shaft and the second rotating shaft are respectively connected to the fixed plate and the support plate.

[0013] Furthermore, the adjusting assembly includes a screw, and a third rotating shaft and a fourth rotating shaft that are rotatably connected to each other;

[0014] One of the third rotating shaft and the fourth rotating shaft is connected to the support plate, and the other is rotatably connected to the screw.

[0015] The fixing plate is provided with screw holes corresponding to the screw rod.

[0016] Furthermore, the third rotating shaft is connected to the support plate, and the fourth rotating shaft is rotatably connected to one end of the screw.

[0017] Furthermore, each end of the support plate has a chamfer.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the mounting bracket of the lidar of this utility model, by setting the gap, when one end of the fixing plate and one end of the bracket plate rotate in opposite directions about the rotation fulcrum in the rotating joint assembly, there is sufficient space at the bottom of the bracket plate to allow the bracket plate to tilt in the opposite direction relative to the fixing plate. This allows the upward viewing angle of the lidar fixed on the bracket plate to be adjusted. Similarly, when one end of the fixing plate and one end of the bracket plate rotate in the forward direction about the rotation fulcrum in the rotating joint assembly, the bracket plate tilts in the forward direction relative to the fixing plate, allowing the downward viewing angle of the lidar to be adjusted. Furthermore, by setting the adjustment component, the bracket plate can be fixed at this angle and kept stable, solving the technical problem of complex operation in the prior art.

Detailed Implementation

[0028] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 7The image shows a mounting bracket for a lidar in one embodiment of the present invention, comprising a fixing plate 100 for connecting to a vehicle, a bracket plate 200 for fixing the lidar 600, at least one rotating joint assembly 300, and at least one adjusting assembly 400. It should be noted that in this example, the fixing plate 100 can be a fixing plate of the prior art, which can be fixed to the vehicle frame.

[0032] To address the technical problem of complex operation in existing lidar brackets, in this embodiment, both the rotating pair assembly 300 and the adjusting assembly 400 are disposed between the fixed plate 100 and the bracket plate 200, thereby forming a gap 500 between the fixed plate 100 and the bracket plate 200 for the bracket plate 200 to rotate in the opposite direction around the rotation fulcrum.

[0033] The rotating pair assembly 300 is located on one side of the gap 500 and is used to rotatably connect the fixing plate 100 and the support plate 200. The adjusting assembly 400 is located on the other side of the gap 500 and is used to adjust the rotation angle between the fixing plate 100 and the support plate 200.

[0034] In practical implementation, by setting the gap 500, when one end of the fixed plate 100 and one end of the support plate 200 rotate in opposite directions around the rotation fulcrum in the rotating joint assembly 300, there is sufficient space at the bottom of the support plate 200, allowing the support plate 200 to tilt in the opposite direction relative to the fixed plate 100. This allows adjustment of the upward viewing angle of the lidar 600 fixed on the support plate 200. Similarly, when one end of the fixed plate 100 and one end of the support plate 200 rotate in the forward direction around the rotation fulcrum in the rotating joint assembly 300, the support plate 200 tilts in the forward direction relative to the fixed plate 100, allowing adjustment of the downward viewing angle of the lidar 600. Furthermore, the adjustment assembly 400 in this embodiment can fix the support plate 200 at this angle and maintain stability, solving the technical problem of complex operation in the prior art.

[0035] For a further understanding of this case, please refer to Figure 6 As shown, the support plate 200 is tilted in the positive direction relative to the fixed plate 100. Please refer to [link / reference]. Figure 7 As shown, the support plate 200 is tilted in the opposite direction to the fixed plate 100.

[0036] In some preferred embodiments, to ensure the stability of the support plate 200 tilted relative to the fixed plate 100, the mounting bracket includes two rotating joint components 300, which are respectively disposed at both ends of one side of the gap portion 500. Simultaneously, using the two rotating joint components 300 as two reference points, a first reference line is constructed along the two reference points, and a second reference line is constructed along the transverse direction of the adjusting component 400. The second reference line intersects the middle of the first reference line. That is, the two rotating joint components 300 and the adjusting component 400 can form a triangular support structure in a two-dimensional plane, further ensuring the stability of the support plate 200 after the angle is adjusted. For details, please refer to [link to relevant documentation]. Figure 5 As shown in the figure, the two thick dashed lines are the first reference line and the second reference line.

[0037] Specifically, the rotating pair assembly 300 includes a first rotating shaft 310 and a second rotating shaft 320 that are rotatably connected to each other. The first rotating shaft 310 and the second rotating shaft 320 are respectively connected to the fixed plate 100 and the support plate 200. The adjusting assembly 400 includes a screw 410, and a third rotating shaft 420 and a fourth rotating shaft 430 that are rotatably connected to each other. One of the third rotating shaft 420 and the fourth rotating shaft 430 is connected to the support plate 200, and the other is rotatably connected to the screw 410. The fixed plate 100 is provided with a screw hole 110 corresponding to the screw 410.

[0038] In some preferred embodiments, the third rotating shaft 420 is connected to the support plate 200, the fourth rotating shaft 430 is rotatably connected to one end of the screw 410, and each end of the support plate 200 has a chamfer.

[0039] Specifically, when the angle of the support plate 200 needs to be adjusted, the screw 410 is rotated so that a portion of the screw 410 rotates within the screw hole 110. Simultaneously, the end of the screw 410 near the fourth rotating shaft 430 can drive one end of the support plate 200 to rise or fall. This rising or falling of one end allows the support plate 200 to tilt relative to the fixed plate 100. Furthermore, during the rotation of the screw 410, the first rotating shaft 310 and the second rotating shaft 320 rotate relative to each other, while the third rotating shaft 420 and the fourth rotating shaft 430 rotate relative to each other. Shaft 430 is rotatable. It should be noted that the threaded connection between screw 410 and screw hole 110 allows the support plate 200 to be maintained at this angle when screw 410 is not rotated, thus simplifying operation. It should also be noted that a hexagonal nut can be fixed on screw 410 by welding. In some specific embodiments, a bearing can be provided at the close ends of the fourth rotating shaft 430 and screw 410 to realize the rotational connection between screw 410 and fourth rotating shaft 430.

[0040] In summary, the mounting bracket for a lidar according to an embodiment of this utility model has at least the following advantages compared to existing brackets:

[0041] In the mounting bracket of the lidar of this utility model, by setting the gap portion 500, when one end of the fixing plate 100 and one end of the bracket plate 200 rotate in opposite directions around the rotation fulcrum in the rotating joint assembly 300, there is sufficient space at the bottom of the bracket plate 200 to allow the bracket plate 200 to tilt in the opposite direction relative to the fixing plate 100. This allows the upward viewing angle of the lidar 600 fixed on the bracket plate 200 to be adjusted. Similarly, when one end of the fixing plate 100 and one end of the bracket plate 200 rotate in the forward direction around the rotation fulcrum in the rotating joint assembly 300, the bracket plate 200 tilts in the forward direction relative to the fixing plate 100, allowing the downward viewing angle of the lidar 600 to be adjusted. Furthermore, the adjustment component 400 in this embodiment can fix the bracket plate 200 at this angle and keep it stable, solving the technical problem of complex operation in the prior art.
