[0001] This utility model relates to the field of lidar installation and adjustment technology, and in particular to a two-dimensional lidar angle adjustment device. Background Technology

[0002] Two-dimensional lidar is an electronic device that uses laser scanning to detect targets. Lidar emits laser pulses, which return to the receiver after encountering a target object. Combined with the angle information output by a high-precision adaptive angle measurement module, two-dimensional planar information of the surrounding 360-degree environment within the measurement range can be obtained.

[0003] Existing technical solutions involve complex structures and long adjustment times for two-dimensional lidar angle adjustment devices. The adjustment methods are not only cumbersome to operate, but also make it difficult to achieve fast and accurate angle positioning.

[0004] To address the aforementioned problems, this utility model provides a two-dimensional lidar angle adjustment device. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a two-dimensional lidar angle adjustment device, comprising a lidar box mounting base, a two-dimensional lidar assembly, and a rotating assembly, wherein the two-dimensional lidar assembly is fixedly connected to the lidar box mounting base via the rotating assembly.

[0007] The rotating assembly includes an adjusting bolt, an adjusting spring, and a rotating shaft. The two-dimensional lidar assembly includes a two-dimensional lidar and a radar adapter box. The two-dimensional lidar assembly also includes a radar mounting box, and a partition plate is fixedly connected inside the radar mounting box.

[0008] The rotating assembly also includes a screw hole on one side of the partition plate, the adjusting bolt is floatingly connected to the adjusting spring, the adjusting spring is sleeved on the outer surface of the adjusting bolt, and the rotating assembly also includes an oblong hole on one side of the radar box mounting base, the adjusting bolt is threadedly connected to the inside of the oblong hole and the screw hole.

[0009] Furthermore, by adjusting the tightness of the adjusting bolt, the adjusting spring is extended or retracted, causing the radar mounting box and the radar box fixing seat to rotate around the rotating shaft. The adjusting bolt swings within the oblong hole provided on the radar box fixing seat, thereby adjusting the angle of the two-dimensional lidar.

[0010] Furthermore, the rotating assembly also includes recesses symmetrically formed on one side of the outer surface of the radar mounting box, and lugs symmetrically fixedly connected to the outer surface of the radar box mounting base. The rotating shaft is inserted into the recesses and lugs to connect the radar box mounting base to the radar mounting box.

[0011] Furthermore, the two-dimensional lidar and the radar adapter box are symmetrically arranged on both sides of the partition plate.

[0012] Furthermore, several connectors are fixedly connected around the two-dimensional lidar. The two-dimensional lidar is threadedly connected to one side of the partition plate through the connectors. Connecting bolts are threadedly connected to the outer surface of the lidar box, and the lidar box is threadedly connected to the outer surface of the lidar mounting box through the connecting bolts.

[0013] Furthermore, the radar box mounting base is disposed on the side of the radar mounting box near the radar adapter box, and the radar box mounting base and the radar mounting box are connected by the adjusting bolt, the adjusting spring and the rotating shaft.

Detailed Implementation

[0024] Please see Figure 1-6 This utility model provides a technical solution: a two-dimensional lidar angle adjustment device, including a lidar box fixing base 1, a two-dimensional lidar component 2 and a rotating component 3, wherein the two-dimensional lidar component 2 is connected to the lidar box fixing base 1 through the rotating component 3.

[0025] The following section will explain the specific settings and functions of its two-dimensional lidar component 2 and rotating component 3.

[0026] In this embodiment: the rotating component 3 includes an adjusting bolt 31, an adjusting spring 32 and a rotating shaft 33; the two-dimensional lidar component 2 includes a two-dimensional lidar 21 and a lidar adapter box 22; the two-dimensional lidar component 2 also includes a lidar mounting box 23; and a partition plate 24 is fixedly connected inside the lidar mounting box 23.

[0027] The rotating assembly 3 also includes a screw hole 34 on one side of the partition plate 24, an adjusting bolt 31 floatingly connected to an adjusting spring 32, and the adjusting spring 32 sleeved on the outer surface of the adjusting bolt 31. The rotating assembly 3 also includes an oblong hole 35 on one side of the radar box mounting base 1, and the adjusting bolt 31 threadedly connected to the inside of the oblong hole 35 and the screw hole 34.

[0028] The effect achieved by the above components is as follows: the floating connection between the adjusting bolt 31 and the adjusting spring 32, together with the screw hole 34 and the oblong hole 35, forms a flexible and precise angle adjustment structure. When the operator rotates the adjusting bolt 31, the adjusting spring 32 extends and retracts accordingly. When the adjusting bolt 31 is tightened, the adjusting spring 32 is compressed, and the resulting elastic force pushes the middle partition 24, thereby driving the radar mounting box 23 to rotate around the rotating shaft 33.

[0029] Specifically, by adjusting the tightness of the adjusting bolt 31, the adjusting spring 32 is extended or retracted, causing the radar mounting box 23 and the radar box fixing seat 1 to rotate around the rotating shaft 33. The adjusting bolt 31 swings within the oblong hole 35 provided on the radar box fixing seat 1, which can adjust the angle of the two-dimensional lidar 21.

[0030] The effect achieved by the above components is that the adjusting bolt 31 swings within the oblong hole 35, realizing the angle adjustment of the two-dimensional lidar 21. Through a simple bolt rotation operation, the detection angle of the lidar can be precisely adjusted to obtain the best detection data.

[0031] Specifically, the rotating assembly 3 also includes a recessed platform 36 symmetrically formed on one side of the outer surface of the radar mounting box 23, and a lug 37 symmetrically fixedly connected to the outer surface of the radar box mounting base 1. The rotating shaft 33 is inserted into the recessed platform 36 and the lug 37 to connect the radar box mounting base 1 with the radar mounting box 23.

[0032] The effects achieved by the above components are as follows: the recessed platform 36 on the outer surface of the radar mounting box 23 and the lug 37 on the outer surface of the radar box fixing seat 1 are connected by a rotating shaft 33, providing a stable support structure for the rotation between the radar mounting box 23 and the radar box fixing seat 1. The symmetrical arrangement of the recessed platform 36 and the lug 37 ensures the coaxiality of the rotating shaft 33, so that the radar mounting box 23 remains stable during the rotation around the rotating shaft 33 without shaking or deviation. The axial positioning of the rotating shaft 33 effectively prevents the axial movement of the rotating shaft 33 during the rotation process, further improving the stability and reliability of the connection and ensuring the accuracy and stability of the angle adjustment process.

[0033] Specifically, the two-dimensional lidar 21 and the radar adapter box 22 are symmetrically arranged on both sides of the partition plate 24. The radar mounting box 23 is located on one side of the two-dimensional lidar 21 and is threadedly connected to the radar box cover 25. The radar box fixing seat 1 is threadedly connected to the other side of the radar mounting box 23.

[0034] The effects achieved by the above components are as follows: the two-dimensional lidar 21 and the radar adapter box 22 are symmetrically arranged on both sides of the partition plate 24, which makes the center of gravity distribution of the entire two-dimensional lidar assembly 2 more uniform. This helps to reduce vibration and noise caused by the center of gravity shift during device operation, and improves the stability of the device. At the same time, the partition plate 24 separates the two, avoiding the impact of electromagnetic interference generated by the two-dimensional lidar 21 during operation on the signal conversion circuit inside the radar adapter box 22, ensuring the stability and reliability of signal transmission, and thus ensuring the accuracy of the detection data of the two-dimensional lidar 21.

[0035] Specifically, several connectors 26 are fixedly connected around the two-dimensional lidar 21. The two-dimensional lidar 21 is threadedly connected to one side of the partition plate 24 through the connectors 26. The outer surface of the lidar box 25 is threadedly connected to the connecting bolts 27. The lidar box 25 is threadedly connected to the outer surface of the lidar mounting box 23 through the connecting bolts 27.

[0036] The aforementioned components achieve the following effects: the radar mounting box 23 and the radar box cover 25 are connected by threads, and the rubber sealing gasket on the edge of the radar box cover 25 fits tightly with the radar mounting box 23, forming a good sealing structure. This effectively prevents external impurities such as dust and moisture from entering the interior of the radar mounting box 23, providing a reliable protective environment for the two-dimensional lidar 21 and the radar adapter box 22, and extending the service life of the equipment. The radar box fixing base 1 and the radar mounting box 23 are connected by threads, which enhances the connection stability between the two and prevents the connection from loosening due to vibration and other factors during equipment operation, ensuring the stability of the entire device structure.

[0037] Specifically, the radar box mounting base 1 is set on the radar mounting box 23 on the side near the radar adapter box 22. The radar box mounting base 1 and the radar mounting box 23 are connected by adjusting bolts 31, adjusting springs 32 and rotating shafts 33.

[0038] The effects achieved by the above components are as follows: This connection method and layout design allows the radar adapter box 22 to be located inside the radar box mounting base 1. The radar box mounting base 1 can provide a certain degree of protection for the radar adapter box 22, reduce the interference of external environmental factors on the signal conversion circuit inside the radar adapter box 22, and ensure the stability and reliability of signal transmission. This improves the accuracy and stability of the detection data of the two-dimensional lidar 21. At the same time, through the connection of the adjusting bolt 31, the adjusting spring 32 and the rotating shaft 33, the angle of the two-dimensional lidar 21 can be flexibly adjusted, meeting the requirements of lidar detection angle in different application scenarios.

[0039] Working principle: When the angle of the two-dimensional lidar 21 needs to be adjusted, the operator uses a tool to rotate the adjusting bolt 31. Since the adjusting bolt 31 is floatingly connected to the adjusting spring 32, and the adjusting spring 32 is sleeved on the outer surface of the adjusting bolt 31; one end of the adjusting spring 32 abuts against the adjusting partition 24, and the other end abuts against the inner surface of the radar box mounting base 1, rotating the adjusting bolt 31 changes the compression or tension state of the adjusting spring 32. When the adjusting bolt 31 is tightened, the adjusting spring 32 is compressed, acting as a buffer, pulling the partition 24 to rotate forward. Because the partition 24 is fixedly connected to the radar mounting box 23, it drives the radar mounting box 23 to rotate forward around the rotating shaft 33. At this time, the adjusting bolt 31 swings along the length of the oblong hole 35, realizing the forward adjustment of the angle of the two-dimensional lidar 21.

[0040] Conversely, when the adjusting bolt 31 is loosened, the adjusting spring 32 elastically returns, pushing the partition plate 24 to cause the radar mounting box 23 to rotate in the opposite direction around the rotating shaft 33. The adjusting bolt 31 also swings within the oblong hole 35, realizing the reverse adjustment of the angle of the two-dimensional lidar 21.

[0041] During the entire adjustment process, the recessed platform 36 on the outer surface of the radar mounting box 23 and the lug 37 on the outer surface of the radar box fixing seat 1 are connected by a rotating shaft 33, providing stable support for the rotation of the radar mounting box 23 and ensuring the smoothness of the rotation process. At the same time, the two-dimensional lidar 21 and the radar adapter box 22 are symmetrically arranged on both sides of the partition plate 24. The partition plate 24 not only separates the two to avoid electromagnetic interference, but also ensures that the center of gravity of the components is uniform, reducing vibration and noise.

[0042] The threaded connection between the radar mounting box 23 and the radar box cover 25, and the threaded connection between the radar box fixing base 1 and the radar mounting box 23, ensure the internal sealing and structural stability of the device, providing a good environment for the stable operation of the two-dimensional lidar 21. The two-dimensional lidar 21 is securely mounted on one side of the partition plate 24 through the connector 26, and the radar box cover 25 is tightly connected to the radar mounting box 23 through the connecting bolts 27, further enhancing the stability and sealing of the device.

[0043] When the entire device needs to be installed on an external device, circumferential positioning is achieved to prevent installation angle deviation.
