Description

Technical Field

[0001] The present invention relates to the field of laser radar technology, and in particular to a laser radar protective shell for an autonomous driving vehicle. Background Art

[0002] LiDAR is a detection mechanism installed on the top of an autonomous vehicle. It is used to detect the driving environment around the vehicle and feed the data back to the on-board computer so that the vehicle can make further judgments and ensure driving safety.

[0003] After searching, it was found that the application number is CN202121075357.8, and the name is a high-safety laser radar. The application raises the problem that the laser radar is easily damaged and troublesome to replace. The radar is protected from damage by the arrangement of a buffer rod. At the same time, it is fixed and installed with screws for easy replacement. However, the current autonomous driving vehicles have good shock absorption effects, and the probability of laser radar being damaged by bumps is extremely low. However, once a collision occurs, the laser radar is likely to be damaged by squeezing and collision. During the use of the above application, once a collision occurs, it is difficult to effectively protect the laser radar, and the laser radar is prone to damage. The current autonomous driving vehicles do not have measures to automatically protect the laser radar separately, and further improvements can be made.

[0004] To this end, we proposed a lidar protective case for autonomous driving vehicles to solve the above-mentioned drawbacks. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a laser radar protective shell for an autonomous driving vehicle.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a laser radar protective shell for an autonomous driving vehicle, comprising a shell and a base, the bottom surface of the shell is integrally connected with a bottom plate, and the bottom plate is inserted into the base, and a rubber strip is filled between the bottom plate and the inner wall of the base, a lifting plate is arranged inside the shell, and a laser radar body is fixedly installed on the top surface of the lifting plate, and an airbag is arranged on the bottom surface of the lifting plate inside the shell, and a spring is connected between the lifting plate and the top surface of the shell, pinholes are opened on the surface around the bottom of the shell, and a side plate is fixedly installed on the top surface of the base outside the pinhole, and a needle is fixedly installed on the surface of the side plate, and the tip of the needle extends into the pinhole.

[0007] Preferably, a side door is provided on one side surface of the shell, and the top surface of the side door is connected to the side wall of the shell through a torsion spring.

[0008] Preferably, a top opening is formed on the top surface of the base, and the shell passes through the top opening.

[0009] Preferably, the size of the bottom plate is larger than the size of the top opening, and the bottom plate is in sliding contact with the inner top surface and inner bottom surface of the base.

[0010] Preferably, both ends of the spring are fixedly connected to the lifting plate and the inner top surface of the shell, respectively, and the spring is distributed on both sides of the laser radar body.

[0011] Preferably, a through hole is opened on the front facade of the shell, and the detection end of the laser radar body faces the through hole.

[0012] Preferably, a wire hole is opened on the rear facade of the shell, and the transmission line of the laser radar body passes through the wire hole.

[0013] Preferably, an inflation valve is installed on the surface of the airbag.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The present invention adopts an airbag and a needle. The needle is installed on the outside of the airbag. When the shell is hit, the shell and the bottom plate move, and the needle pierces the airbag. The airbag is instantly deflated, and the spring is instantly extended, pushing the lifting plate and the laser radar body downward and shrinking them into the shell, thereby avoiding the problem of further squeezing and damaging the laser radar body, improving the protection efficiency of the laser radar body, and improving the safety of use. The needle is installed around the shell. No matter which direction the shell is hit, it can trigger the piercing of the airbag in time to complete the protection function, and the work efficiency is higher.

[0016] (2) The present invention adopts an openable side door. When the airbag is punctured, the staff can turn the side door to take out the punctured airbag, and then put a new airbag under the lifting plate and inflate it through the inflation valve until the laser radar body is pressed against the bottom surface of the shell. The replacement can be completed quickly, and the replacement is convenient and quick. At the same time, the squeezed rubber strip will automatically push the bottom plate and the shell to reset through elastic force, further improving the convenience of use. In addition, the device has a simple structure, occupies a small area, and is more flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
