Description

Technical Field

[0001] This utility model relates to the field of automotive lidar, and in particular to a lidar component for autonomous vehicles. Background Technology

[0002] An existing patent (publication number: CN207908673U) discloses a lidar assembly for autonomous vehicles. It includes a lidar with a protective device on its outer side. This protective device is fixedly connected to the vehicle's roof and encapsulates the lidar inside. This invention protects the lidar by providing a protective device on its outer side, which is fixedly connected to the vehicle's roof and encapsulates the lidar inside. However, this device, where "the lower end of the light-transmitting cover passes through the mounting hole and is adhered to the base," relies on the base below the lidar for support. Since the base is at a fixed angle, after installation, it may be impossible to adjust the camera angle according to the actual situation of the device, thus having certain limitations. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a laser radar assembly for autonomous vehicles. The assembly utilizes a worm motor inside the device base to drive a worm gear, which in turn rotates a worm wheel at the bottom of the radar bracket. This, in turn, adjusts the orientation of the laser radar unit within the radar frame. Furthermore, an angle motor on the side of the angle bracket adjusts the laser radar unit's angle accordingly. Therefore, when installed on an autonomous vehicle, the assembly allows for adjustments to the orientation and angle of the laser radar unit based on actual needs, thereby increasing its adaptability.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An autonomous vehicle LiDAR assembly includes a device base, a worm shaft, a worm motor, a central shaft, an angle motor, a locking pin, and a LiDAR body. The device base has a mounting platform on its side and an internal cavity. A protective plate screw groove is located on the side of the internal cavity. The protective plate is fixedly connected to the lower part of the protective plate screw groove via protective plate screws. The side of the internal cavity is fixedly connected to a worm gear frame. The worm gear is fixedly connected to a worm shaft inside the worm. The worm gear frame is adapted to the worm shaft and connects to it. The worm shaft rotates inside the worm gear frame. The rear of the worm gear frame is fixedly connected to a worm motor. The front of the worm motor shaft is fixedly connected to the worm shaft. The internal cavity is fixedly connected to a worm wheel frame. The worm wheel frame is fixedly connected to a worm wheel bearing frame. The worm wheel bearing frame is adapted to the worm wheel and connects to it. The worm wheel rotates inside the worm wheel bearing frame and meshes with the worm gear on its side. The lower part of the LiDAR bracket has a central shaft, and the upper part of the worm wheel is fixedly connected to the central shaft. The upper part of the internal cavity has a central shaft groove.

[0006] The central shaft groove is adapted to the central shaft and is connected to the central shaft. The central shaft rotates inside the central shaft groove. The upper part of the radar bracket is fixedly connected to the angle frame, and the angle frame has an angle shaft positioning groove inside.

[0007] The rear part of the radar frame is fixedly connected to the angle axis, the angle axis positioning groove is adapted to the angle axis, the angle axis positioning groove is connected to the angle axis, the angle axis rotates inside the angle axis positioning groove, and the side of the angle frame has a motor groove. Beneficial effects

[0008] 1. During the use of the LiDAR component for autonomous vehicles, the worm gear motor inside the device base drives the worm to rotate, which in turn drives the worm wheel at the bottom of the radar bracket to rotate. This causes the radar bracket to adjust the orientation of the LiDAR unit inside the radar frame. In conjunction with the angle motor on the side of the angle bracket, the LiDAR unit inside the radar frame is adjusted to a certain angle. Thus, after the device is installed on an autonomous vehicle, the orientation and angle of the LiDAR unit can be adjusted according to actual needs, thereby increasing the adaptability of the device.

[0009] 2. During the use of the LiDAR component for autonomous vehicles of this utility model, by disassembling the screws of the radar component at the rear of the radar frame and pulling out the LiDAR body inside the clip, the LiDAR body can be replaced separately from the equipment, thereby further facilitating personnel maintenance.

[0010] 3. During the use of the LiDAR component for autonomous vehicles of this utility model, the worm motor inside the equipment base drives the internal worm gear to rotate. Because the transmission principle of the worm and worm gear has a self-locking function, the equipment maintains the adjusted angle during operation, thereby enhancing the stability of the equipment.
