Embodiment 1

[0074] see Figure 1-Figure 5 , the vehicle laser radar installation structure provided in this embodiment mainly includes: 1. the laser radar body, 2. the driving member, 3. the screw rod, 4. the limit block, 5. the moving block, 6. the gear, 7. the cover plate , 8, reflector, 9, connecting rod, 10, cleaning scraper, 11, rack, 12, guide rail, and hinges A1, A2, A3. Among them, the laser radar body 1 is fixedly installed inside the vehicle cover 20; the driving part 2 is the power source for switching the state of the cover plate 7; the driving part 2 should use a stepping motor capable of precise control; Coupling connection (or direct fixed connection); the limit block 4 is fixedly connected with the screw rod 3, and its function is to limit the limit position of the moving block 5, so as to achieve the precise positioning of the two limit positions of the cover plate 7; the moving block 5 is installed On the screw mandrel 3, it cooperates with the screw mandrel 3 to comple...

Embodiment 2

[0080] see Image 6 Compared with Embodiment 1, the embodiment of the present invention provides a laser radar installation structure for vehicles, which omits the reflective mirror 8 and adopts a scheme of only one reflection (reflection is realized from the inside of the cover plate 7), which can also realize the corresponding adjustment of the laser radar body 1. function and simplify the structure. Similarly, the laser radar body 1 in this embodiment can also be used with the reflector 8, and the laser radar body 1 is arranged in front of the reflector 8, behind the reflector or other positions, which are not specifically limited here.

Embodiment 3

[0082] see Figure 7-Figure 8 , in the vehicle laser radar installation structure provided in this embodiment, the motor and the rotating shaft installed on the cover plate 7 cooperate to realize the rotation of the motor to drive the cover plate 7 to rotate around the rotating shaft, and the cover plate structure can be realized by controlling the positive and negative rotation of the motor Flipping in two directions realizes the detection function of the laser radar body 1 on the front and rear signals of the vehicle in different usage scenarios.

[0083] Similarly, the reception of signals from the left and right directions of the vehicle by the lidar body 1 can be realized through the installation direction of the rotation shaft. Furthermore, signal detection in different directions of the lidar body 1 can be realized by adding motors and rotating shafts (such as rotating shafts and motors that drive the cover plate to turn forward, backward and left and right). The solut...

Abstract

The invention discloses an automotive laser radar installation structure which comprises a laser radar body, a cover plate and a driving part. The laser radar body is fixed in the vehicle covering part; an opening is formed in a preset position of the vehicle covering part; the cover plate can be movably mounted on the vehicle covering part and is used for sealing and covering the opening; the cover plate has an open state and a closed state; the driving part is installed in the vehicle covering part and used for driving the cover plate to switch the state. When the cover plate is in the open state, the inner side face of the cover plate can reflect laser outside the vehicle covering part to the laser radar body. In the vehicle laser radar mounting structure, the laser radar body is arranged in the vehicle covering part, so that the wind resistance and wind noise performance of the whole vehicle is prevented from being influenced by a convex structure formed by mounting the laser radar outside the vehicle, the frequency of polluting the laser radar by external pollutants can be reduced, and the damage of external impurities to the laser radar body is reduced; the service life is prolonged and the later maintenance cost is reduced. The invention further provides an automobile.

Description

technical field [0001] The present invention relates to the technical field of machinery industry, and more specifically, relates to a vehicle laser radar installation structure, and also relates to a vehicle. Background technique [0002] At present, the development of automobile intelligent driving is growing day by day, and lidar, as an important component of intelligent driving system, is increasingly used in automobiles. [0003] The lidar is relatively large, so the lidar in the car is generally arranged outside the car, which will cause a protruding structure on the outside of the car and affect the wind resistance and wind noise performance of the whole car. [0004] Therefore, it is an urgent problem to be solved by those skilled in the art how to avoid the formation of a protruding structure on the outside of the vehicle due to the placement of the lidar on the outside of the vehicle, which will affect the wind resistance and wind noise performance of the vehicle. ...
