The protruding portion 211 is located outside the mounting groove 111, and the protruding portion 211 arches in a direction away from the embedded portion 212.
Since the embedded portion 212 can be constructed in a plate-like structure, the depth of the mounting groove 111 can be set small so as not to occupy too much of the internal space of the vehicle body 1.
In an exemplary embodiment, the panel surface of the insert 212 facing outward of the mounting groove 111 is flush with the outer surface of the vehicle body 1. In the present embodiment, the plate surface of the fitting portion 212 facing outward of the mounting groove 111 is a top surface 2113 of the fitting portion 212, which is flush with the outer surface of the ceiling 11 of the vehicle body 1.
In this way, the outward facing surface of the insert 212 smoothly transitions with the outer surface of the body 1, so that the wind resistance of the vehicle as a whole is smaller and the wind noise is also smaller.
In an exemplary embodiment, as shown in fig. 9, the protruding portion 211 is connected to a side of the insertion portion 212 facing away from the vehicle body 1 and protrudes outside the vehicle body 1. The sensor assembly is disposed within the boss 211. The boss 211 is provided with a light-transmitting window 2115. The light-transmitting window 2115 is provided at the side of the boss 211. The light-transmitting window 2115 penetrates the boss 211. When the sensor assembly comprises a visual sensor, the visual sensor can acquire images of the surrounding environment of the automobile through the light-transmitting window 2115; when the sensor assembly includes a lidar, laser energy emitted by the lidar passes through the light-transmissive window 2115.
In one illustrative embodiment, the boss 211 is made of fiberglass. The heat conducting performance of the protruding portion 211 is good, and heat emitted by the sensor assembly can be rapidly emitted to the surrounding environment through the protruding portion 211, so that the overall heat radiating performance is improved. Meanwhile, the glass fiber is adopted to manufacture the protruding portion 211, so that the cost is low.
In one illustrative embodiment, the light-transmitting window 2115 is provided on a forward side of the boss 211.
Thus, the light transmission window 2115 has a larger light transmission range, the laser radar has a larger scanning range, and the vision sensor can have a larger imaging range.
In an exemplary embodiment, the host 21 further includes a light-transmissive plate 2116. The light-transmitting plate 2116 is configured in a plate-like structure. The light-transmitting plate 2116 may be made of a transparent material or a translucent material. The light-transmitting plate 2116 covers the light-transmitting window 2115, and seals the light-transmitting window 2115. The light-transmitting plate 2116 is inclined rearward, and the distance from the light-transmitting plate 2116 to the embedded portion 212 becomes gradually larger in the direction from the front end 2111 of the boss 211 to the rear end 2112 of the boss 211. The front end 2111 of the boss 211 has an end surface that faces forward of the light-transmitting plate 2116.
The light-transmitting plate 2116 prevents rainwater dust from entering the housing 210 from the light-transmitting window 2115 to damage the sensor assembly, and the light-transmitting plate 2116 also functions to guide upward movement of the airflow in front when the automobile is traveling forward.
In an exemplary embodiment, the middle portion of the light-transmitting plate 2116 protrudes toward the front of the vehicle body 1. The middle of the light-transmitting plate 2116 is more forward than the two sides of the light-transmitting plate 2116, so that the light-transmitting plate 2116 can guide a part of air flow to the two sides when the automobile runs forward, and wind resistance and wind noise are further reduced.
In one illustrative embodiment, the mounting groove 111 is provided at the 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 vehicle, so that the detection blind area is further reduced.
In an exemplary embodiment, as shown in fig. 7 and 10, the environment sensing device 2 further comprises a seal 22. The seal 22 is an elastic member. The seal 22 may be made of rubber or silicone. The seal 22 is configured in the shape of a ring. The seal member 22 is fitted over the fitting portion 212, and the seal member 22 is located between the side surface of the fitting portion 212 and the inner side wall of the mounting groove 111. The seal 22 is used to close the gap between the embedded portion 212 and the inner wall of the mounting groove 111. The seal 22 prevents rainwater from entering the vehicle body 1 from the gap, enhancing the sealing of the environment sensing device 2.
In one illustrative embodiment, an annular channel 221 is disposed within the seal 22, the annular channel 221 extending circumferentially of the seal 22. Thus, the deformation range of the sealing element 22 is larger, the wider gap can be blocked, and the sealing performance of the sealing element 22 is better.
In an exemplary embodiment, as shown in fig. 7 and 10, the environment sensing device 2 further comprises a second gasket 23. The second gasket 23 has elasticity or flexibility. The second gasket 23 may be made of silica gel or rubber. The second gasket 23 covers the groove bottom of the mounting groove 111. The second gasket 23 is interposed between the bottom of the mounting groove 111 and the bottom surface of the fitting portion 212 facing the bottom.
The second gasket 23 can seal the gap between the bottom of the mounting groove 111 and the bottom surface of the embedded portion 212, further enhancing the sealing performance of the automobile.
In an exemplary embodiment, as shown in fig. 11 and 12, a water guiding groove 2117 is further provided on the light-transmitting plate 2116. The water guide groove 2117 is recessed into the boss 211. The water guide grooves 2117 are configured as stripe grooves, and the water guide grooves 2117 extend along the edge of the light-transmitting plate 2116. The water guide grooves 2117 may be configured in a ring shape, and are distributed over the edges of the light-transmitting plate 2116.
In raining, the water flowing onto the light-transmitting plate 2116 from the boss 211 falls into the uppermost water guiding groove 2117 first, and then flows along the water guiding groove 2117 to the bottom of the light-transmitting plate 2116, that is, the water is guided by the water guiding 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, while 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 via 113. The first via hole 113 may be provided at a middle portion of the groove bottom 112 of the mounting groove 111. The second gasket 23 is provided with a second via hole 231, and the second via hole 231 is aligned with the first via hole 113.
In this way, the first wire through hole 113 and the second wire through hole 231 communicate the inside of the vehicle body 1 with the host 21, and the cable connected with the sensor assembly of the host 21 can extend into the inside of the vehicle body 1 through the second wire through hole 231 and the first wire through hole 113, so that the wiring is convenient and reasonable.
