Description

Technical Field

[0001] This utility model relates to the field of lidar technology, specifically to a folding device for automotive lidar. Background Technology

[0002] LiDAR is a key detection component for autonomous vehicles. The laser emitted by the LiDAR probe can quickly and effectively detect the distance and speed of obstacles, pedestrians, and other vehicles around the car during its operation, and then feed the information back to the onboard computer to ensure driving safety.

[0003] A search revealed that patent application CN218929344U discloses a folding device for an automotive lidar system, comprising a base, a mounting plate rotatably connected to the base, and a drive assembly for flipping the mounting plate. The lidar is mounted on one side of the mounting plate, and the base is embedded in the vehicle. The base has a first groove with an opening flush with the outer surface of the vehicle. The mounting plate is positioned at the opening, and the first groove and the mounting plate cooperate to form a closed first cavity, enabling automatic folding of the lidar to prevent theft by outsiders.

[0004] However, due to the configuration of the drive assembly and mounting plate, the drive assembly causes the mounting plate to flip, thereby extending the radar to the outside. This results in an excessively large external window on the vehicle body, and the mounting plate is also exposed to the outside, leading to a poor appearance and poor performance. At the same time, because the mounting plate can rotate to seal the opening, the sealing performance of the opening is low, and rainwater and dust from the outside can easily enter its interior, resulting in poor sealing performance.

[0005] Therefore, we propose a folding device for automotive lidar. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a folding device for automotive lidar, which solves the problems of poor performance and poor sealing of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a folding device for automotive lidar, comprising a vehicle body shell, wherein a fixing frame located inside the vehicle body shell is mounted on the inner side of the vehicle body shell.

[0008] A telescopic cylinder is fixedly installed on the right side of the fixed frame, and a laser radar box is mounted on the output end of the telescopic cylinder. A window is opened on the outer wall of the vehicle body shell, and a sealing groove is opened on the inner side of the vehicle body shell. A fixed cylinder is fixedly installed on the right side of the laser radar box, and a lens of the same specification is mounted on the right side of the fixed cylinder.

[0009] An electric telescopic rod A is fixedly installed on the right side of the lidar box, with a connecting plate fixedly installed on the telescopic end of the electric telescopic rod A. An electric telescopic rod B of the same specifications is fitted on the bottom surface of the connecting plate. A fixing block is fixedly installed at the bottom end of the electric telescopic rod B. A cover plate of the same specifications is fitted on the right side of the fixing block. A sealing plate of the same specifications is fixedly installed on the right side of the cover plate.

[0010] Preferably, a limiting ring that matches the specifications of the sealing groove is fixedly installed on the outer wall of the fixed cylinder, which can limit the movement of the fixed cylinder and the lens and prevent shaking.

[0011] Preferably, a through positioning hole is provided on the right side of the lidar box, and a positioning rod that is corresponding to the positioning hole and of the same specification is fixedly installed on the inner side of the vehicle body shell. The positioning rod slides in the positioning hole, so that when the lidar box moves left and right, the positioning rod can limit its movement, ensuring its stability and accuracy, and improving the use effect.

[0012] Preferably, the outer walls of the cover plate and the sealing plate are fitted with a rubber layer to improve their sealing performance.

[0013] Preferably, the cover plate is equipped with a pressure sensor inside, which can prevent excessive pressure from damaging the vehicle body shell.

[0014] Preferably, the electric telescopic rod A and the electric telescopic rod B are equipped with displacement sensors of compatible specifications, which can ensure the accuracy of their displacement.

[0015] 1. This automotive lidar folding device, through the setting of a telescopic cylinder and a window, allows the lidar box and lens to be moved horizontally when the vehicle is moving, thereby revealing the lens through the window. It is simple and convenient, with a small window size and neat appearance, improving the convenience and effectiveness of use.

[0016] 2. Simultaneously, through the setting of the cover plate and sealing plate, after the telescopic cylinder drives the lens to retract, the electric telescopic rod A and electric telescopic rod B drive the cover plate to move towards the window. The sealing plate is located in the sealing groove, and the cover plate contacts the inner wall of the vehicle body shell, improving its sealing performance and preventing rainwater and dust from entering the inside. It has high sealing performance and good protection effect. Attached Figure Description
