Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, specifically to an environmental perception radar mounting structure for autonomous vehicles. Background Technology

[0002] Autonomous vehicles are vehicles that achieve autonomous driving through technologies such as sensors, cameras, radar, and artificial intelligence. They can perceive their environment, plan routes, and perform driving operations without human intervention. Based on the degree of automation, they are divided into five levels, L1-L5, with L5 being fully autonomous driving. Autonomous driving technology aims to improve traffic efficiency, reduce accidents, and enhance the travel experience. Currently, with the development of autonomous driving technology, vehicles can be given more possibilities. Autonomous driving technology requires vehicles to be equipped with environmental perception radar, which perceives the surrounding environment to avoid obstacles and adjust the driving route. The environmental perception radar needs to be fixed to the vehicle through a mounting structure.

[0003] For example, according to authorization announcement number CN214775645U, a car radar mounting structure is used to install car components and can respectively limit the car components in the X, Y, and Z directions of the vehicle body. It includes a mounting bracket with a mounting slot open on one side. The insertion of the car component into the mounting slot limits the car component in the X and Z directions. The mounting bracket has a movable locking part at one end of the mounting slot opening, and a resilient pushing part at the other end of the mounting bracket, corresponding to the movable locking part. The movable locking part is configured to have a first state where it is located on the mounting bracket, allowing the car component to enter and exit the mounting slot, and a second state where the car component is inserted and limited in the Y direction in cooperation with the resilient pushing part. This utility model's mounting structure can limit the installed car components in the X, Y, and Z directions, and facilitates the installation and replacement of car components.

[0004] However, the aforementioned technologies use a snap-fit ​​method to fix the car radar, but the vibration of the car is significant when it is in motion, and the snap-fit ​​method is not stable, causing the radar to shake and thus affecting the accuracy of radar perception. Therefore, the market urgently needs to develop an environmental perception radar installation structure for autonomous vehicles to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide an environmental perception radar installation structure for autonomous vehicles, in order to solve the problem mentioned in the background art that the existing technology uses a snap-fit ​​method to fix the car radar, but the car vibrates a lot when it is driving, and the snap-fit ​​method is not stable, causing the radar to shake, which in turn affects the accuracy of radar perception.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmental perception radar mounting structure for an autonomous vehicle, comprising a partial car shell, a semi-cylindrical protective cover connected to the front end of the partial car shell, positioning posts fixedly connected to the upper and lower ends of both sides of the rear end face of the semi-cylindrical protective cover, an environmental perception radar connected to the rear end of the partial car shell, connecting wing plates fixedly connected to both sides of the environmental perception radar, and a positioning plate connected to the front end of the environmental perception radar.

[0007] Preferably, a rectangular sealing ring is provided between the rear end edge of the semi-cylindrical protective cover and the front end of the partial outer shell of the vehicle.

[0008] Preferably, the connecting wing plates on both sides of the environmental perception radar are fixedly connected to the positioning plate by the first screw.

[0009] Preferably, positioning holes are provided at both the top and bottom ends of both sides of the positioning plate, and the four positioning posts pass through the four positioning holes on the positioning plate after passing through the partial outer shell of the car.

[0010] Preferably, each of the four positioning posts has an internal threaded hole, and a clamping tube is fitted onto the rear end of the vehicle partial housing and connected to each of the four positioning posts. A limit ring is fixedly connected to the front end of the clamping tube.

[0011] Preferably, the semi-cylindrical protective cover, the automotive partial shell, and the positioning plate are connected and fixed by a second screw passing through the middle of the limiting ring and then inserted into the internal threaded hole.

[0012] Preferably, a first circular opening is provided in the middle of the partial outer shell of the vehicle, a second circular opening is provided in the middle of the rear end face of the semi-cylindrical protective cover, and a probe is provided in the middle of the front end of the environmental perception radar. The probe extends into the interior of the semi-cylindrical protective cover by passing through the first circular opening and the second circular opening in sequence.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the clamping tube and the second screw are used to fix the semi-cylindrical protective cover, the partial outer shell of the car and the positioning plate simultaneously, which enhances the stability of the overall structure and effectively avoids the problem of radar shaking caused by vibration during vehicle operation.

[0015] (2) In this utility model, the precise positioning of the environmental perception radar is achieved by the cooperation of the positioning post and the positioning hole, ensuring that the probe can accurately pass through the first circular opening and the second circular opening, thereby improving the stability and accuracy of radar perception.

[0016] (3) In this utility model, the design of the rectangular sealing ring achieves a sealed connection between the semi-cylindrical protective cover and the partial outer shell of the car, preventing water vapor and dust from entering, protecting the probe from damage, and extending the service life of the environmental perception radar.

The positioning plate 4 has positioning holes 401 on both sides and at the top and bottom. The four positioning posts 203 pass through the partial outer shell 1 of the car and then through the four positioning holes 401 on the positioning plate 4. During installation, the semi-cylindrical protective cover 2 is first installed at the front end of the partial outer shell 1. The semi-cylindrical protective cover 2 is positioned by the four positioning posts 203 passing through the partial outer shell 1 of the car. Then, the positioning plate 4 with the environmental sensing radar 3 is placed at the rear end of the partial outer shell 1, and the four positioning posts 203 pass through the four positioning holes 401 on the positioning plate 4 to position and connect the positioning plate 4 and the environmental sensing radar 3, so that the probe 303 can accurately extend into the interior of the semi-cylindrical protective cover 2 along the first circular opening 101 and the second circular opening 201.

[0024] Please see Figure 3 and Figure 4 Each of the four positioning posts 203 has an internal threaded hole 204. A clamping tube 5 is fitted onto the rear end of the automotive partial housing 1 and onto each of the four positioning posts 203. A limit ring 501 is fixedly connected to the front end of the clamping tube 5. The semi-cylindrical protective cover 2, the automotive partial housing 1, and the positioning plate 4 are connected and fixed by a second screw 6 passing through the middle of the limit ring 501 and then inserted into the internal threaded hole 204, so that the semi-cylindrical protective cover 2, the automotive partial housing 1, and the positioning plate 4 are fixed synchronously, thereby achieving stable installation of the environmental perception radar 3.

[0025] Please see Figure 2 and Figure 3 A rectangular sealing ring 202 is provided between the rear end edge of the semi-cylindrical protective cover 2 and the front end of the automotive partial housing 1 to seal the semi-cylindrical protective cover 2 and the automotive partial housing 1, preventing moisture from entering the interior of the semi-cylindrical protective cover 2 and damaging the probe 303.
