When the sensor assembly comprises a vision sensor, the vision sensor can acquire the surrounding environment image of the automobile through the light-transmitting window 2115; when the sensor assembly includes a lidar, laser light emitted by the lidar can pass through the light-transmissive window 2115.

In one exemplary embodiment, the projections 211 are made of fiberglass. The heat conductivity of the convex part 211 is good, and the heat emitted by the sensor assembly can be rapidly emitted to the surrounding environment through the convex part 211, so that the overall heat radiation performance is improved. Meanwhile, the glass fiber is adopted to manufacture the convex part 211, so that the cost is low.

In an exemplary embodiment, the light transmissive window 2115 fills a forward facing side of the protrusion 211.

Thus, the light-transmitting window 2115 has a larger light-transmitting range, the scanning range of the laser radar is larger, and the shooting range of the vision sensor can be larger.

In an exemplary embodiment, the host 21 further includes a light transparent panel 2116. The light-transmitting plate 2116 is configured as a plate-like structure. The light-transmitting plate 2116 can be made of a transparent material or a semitransparent material. The light-transmissive plate 2116 covers the light-transmissive window 2115, and seals the light-transmissive window 2115. The light-transmitting plate 2116 is inclined rearward, and the distance from the light-transmitting plate 2116 to the fitting portion 212 gradually increases in the direction from the front end 2111 of the protruding portion 211 to the rear end 2112 of the protruding portion 211. The end surface of the front end 2111 of the protruding portion 211 is a surface of the light-transmitting plate 2116 facing forward.

The light-transmitting plate 2116 prevents rainwater and dust from entering the housing 210 through the light-transmitting window 2115 to damage the sensor module, and the light-transmitting plate 2116 also serves to guide the upward movement of the air flow in front when the vehicle is traveling forward.

In an exemplary embodiment, the center portion of the light-transmitting plate 2116 protrudes forward of the vehicle body 1. The middle of the light-transmitting plate 2116 is positioned forward relative to the sides of the light-transmitting plate 2116, so that the light-transmitting plate 2116 can also guide a part of the air flow to the two sides when the automobile is running forward, and the wind resistance and the wind noise are further reduced.

In an exemplary embodiment, the mounting slot 111 is disposed at a front end 2111 of the ceiling 11. That is, the mounting groove 111 is provided at one end of the ceiling 11 near the front windshield. In this way, the environment sensing device 2 is also located at the front end 2111 of the ceiling 11, and the environment sensing device 2 can measure a wide area in front of the measuring automobile, so that the detection blind area is further reduced.

In an exemplary embodiment, as shown in fig. 7 and 10, the environmental sensing device 2 further includes a seal 22. The sealing member 22 is an elastic member. The seal 22 may be made of rubber or silicone. The seal 22 is of annular design. The sealing member 22 is fitted over the insertion portion 212, and the sealing member 22 is located between the side surface of the insertion portion 212 and the inner side wall of the mounting groove 111. The sealing member 22 is used to close the gap between the insertion portion 212 and the inner wall of the mounting groove 111. The sealing member 22 prevents rainwater from entering the vehicle body 1 through the gap, and enhances the sealing of the environmental sensor 2.

In an exemplary embodiment, an annular channel 221 is provided within seal 22, and annular channel 221 extends circumferentially of seal 22. Thus, the deformation range of the sealing member 22 is larger, a wider gap can be blocked, and the sealing performance of the sealing member 22 is better.

In an exemplary embodiment, as shown in fig. 7 and 10, the environmental sensing device 2 further includes a second gasket 23. The second gasket 23 has elasticity or flexibility. The second seal 23 may be made of silicone or rubber. The second packing 23 covers the bottom of the full installation groove 111. The second gasket 23 is interposed between the groove bottom of the mounting groove 111 and the bottom surface of the fitting portion 212 facing the groove bottom.

The second gasket 23 can seal the gap between the groove bottom of the mounting groove 111 and the bottom surface of the embedding portion 212, further enhancing the sealing performance of the automobile.

In an exemplary embodiment, as shown in fig. 11 and 12, the light-transmitting plate 2116 is further provided with a water chute 2117. The water guide groove 2117 is recessed into the boss 211. The water guide 2117 is configured as a bar groove, and the water guide 2117 extends along an edge of the light-transmitting plate 2116. The water guide slots 2117 may be configured in a ring shape, which is filled with the edge of the light-transmitting plate 2116.

In the case of rain, the water flowing from the protruding portion 211 to the light-transmitting plate 2116 first falls into the uppermost water guide groove 2117 and then flows along the water guide groove 2117 to the bottom of the light-transmitting plate 2116, i.e., the water is guided by the water guide groove 2117 to flow along the edge of the light-transmitting plate 2116, so that the water does not affect the detection of the sensor assembly, and the water accumulation on the light-transmitting plate 2116 can be prevented.

In an exemplary embodiment, as shown in fig. 7, the groove bottom 112 of the mounting groove 111 is provided with a first wire passing hole 113. The first wire passing hole 113 may be disposed at a middle portion of the groove bottom 112 of the mounting groove 111. The second gasket 23 is provided with a second wire passing hole 231, and the second wire passing hole 231 is aligned with the first wire passing hole 113.

Therefore, the first wire passing hole 113 and the second wire passing hole 231 communicate the interior of the vehicle body 1 with the main machine 21, and a cable connected with a sensor assembly of the main machine 21 can extend into the vehicle body 1 through the second wire passing hole 231 and the first wire passing hole 113, so that wiring is convenient and reasonable.
