Description

Technical Field

[0001] This utility model relates to the field of laser scanning sensor and millimeter-wave radar identification technology, and in particular to an all-weather protection device for integrated laser radar. Background Technology

[0002] With the rapid development of laser scanning technology, laser scanning sensors are widely used in various fields. Simultaneously, the combination of laser scanning technology and millimeter-wave radar scanning technology is becoming increasingly prevalent in practical applications, especially with the widespread adoption of intelligent devices such as smart factories, intelligent transportation, autonomous driving, and smart equipment. LiDAR and millimeter-wave radar complement each other, offering complementary advantages. LiDAR boasts high accuracy, but its penetration in rain, snow, and fog can negatively impact its accuracy. Millimeter-wave radar offers better penetration, but its accuracy is not as high as that of LiDAR. Existing patent CN206684292U discloses an integrated mounting bracket for LiDAR and millimeter-wave radar, comprising a horizontally arranged common substrate, a first plate and a second plate vertically arranged on the upper and lower sides of the common substrate, respectively. The first and second plates are parallel to each other, and the distance between them is less than the thickness of the LiDAR. A support plate is vertically arranged on the surface of the second plate away from the first plate. The support plate has mounting holes for fixing to the front bumper beam of a vehicle with screws. The second plate has symmetrically arranged mounting holes for the LiDAR. The first plate has mounting holes for the millimeter-wave radar. The common substrate has wiring harness mounting holes. This integrated mounting bracket for lidar and millimeter-wave radar can simultaneously accommodate both. While the device can mount both, it lacks external protection for the radars. However, many outdoor scenarios require the use of both types of radar for extended periods of open-air detection. Therefore, a protective device integrating both radars is needed to provide external protection while allowing them to complement each other's scanning capabilities. Utility Model Content

[0038] like Figures 1 to 4 As shown in the figure, this embodiment discloses an all-weather protection device for integrated laser radar, including a main housing 1. An external mounting plate 2 is provided on the outer edge of the mounting port at the rear of the main housing 1, and a reserved mounting hole 2-2 is provided on the external mounting plate 2. The entire device can be installed on an external device by means of the reserved mounting hole 2-2.

[0039] The front of the main housing 1 is equipped with a lidar window 1-1 and a millimeter-wave radar window 1-2, with the millimeter-wave radar window 1-2 located on either side below the lidar window 1-1. Inside the main housing 1, a lidar 6 and two millimeter-wave radars 7 are installed. The lidar 6 is detachably mounted on a lidar mounting bracket 4, which is located inside the main housing 1. The two millimeter-wave radars 7 are mounted on either side of the lidar 6. The viewing window of the lidar 6 corresponds to lidar window 1-1, and the viewing window of the millimeter-wave radar 7 corresponds to millimeter-wave radar window 1-2. A main sealing plate 3 is installed inside the mounting opening of the main housing 1, and the main sealing plate 3 is detachably connected to the external mounting plate 2 via bolt assemblies. The main sealing plate 3 seals the lidar 6 and the two millimeter-wave radars 7 within the main housing 1, effectively protecting them. In this embodiment, sealing strips are provided around the millimeter-wave radar window 1-2 at the contact points with the millimeter-wave radar 7 to increase the sealing performance, thereby sealing the millimeter-wave radar 7 except for its own window inside the device.

[0040] In this embodiment, a sealing groove 2-1 is provided on the contact surface between the external mounting plate 2 and the main sealing plate 3, and a sealing strip is provided in the sealing groove 2-1 to increase the sealing performance.

The base frame 4-4 is fixedly connected to the back plate 4-3 by bolt assemblies. The back plate 4-3 is fixedly connected to the main body of the lidar 6 by bolt assemblies. This achieves a fixed connection between the lidar 6 and the base plate of the main housing 1.

[0043] The inner mounting bracket 4-1 is fixedly mounted on the inner wall of the main housing 1. The head and neck of the lidar 6 are held in the inner mounting bracket 4-1. The fixing plate 4-2 is connected to the inner mounting bracket 4-1 by bolt assembly, and the fixing plate 4-2 confines the head and neck of the lidar 6 within the inner mounting bracket 4-1.

[0046] The rear of the connecting frame 4-1-1 has a mounting slot 4-1-2. A head mounting cover 4-1-3 is mounted on the connecting frame 4-1-1, positioned above the mounting slot 4-1-2. The head of the lidar 6 is inserted into the mounting slot 4-1-2. The mounting slot 4-1-2 also contains an inverted conical structure that mates with the neck of the lidar 6 to limit its movement. The viewing window of the lidar 6 corresponds to the viewing port 4-1-4, and a sealing strip is provided between the connecting frame 4-1-1 and the viewing window of the lidar 6, ensuring that the lidar 6, except for its own viewing window, is sealed inside the device. To install the lidar 6, first install the back plate 4-3 onto the back of the lidar 6 body. Then, align the head of the lidar 6 with the mounting slot 4-1-2 and insert it. After placement, connect the fixing plate 4-2 to the threaded hole on the connecting frame 4-1-1 using bolt assemblies. After the fixing plate 4-2 is installed, the back plate 4-3 and the base frame 4-4 are connected together with screws.

[0047] In this embodiment, sealing strips are provided on the contact surfaces of the connecting frame 4-1-1, the fixing plate 4-2 and the lidar 6 to increase the sealing performance.
