The term "and/or" as used in the specification of this application includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 10, the present application provides a lidar decorative plate structure assembly 100, and the lidar decorative plate structure assembly 100 is used for installing and sealing a lidar 101 so that the lidar 101 is not affected by external rainwater or dust, thereby operating normally.

The sealing structure of the radar decorative plate of the automobile in the related art is very rough. For example, in some positions, the radar decorative plate is directly lapped on the glass, the sealing is unreliable, and the adhesive tape or foam is exposed to the outside and is easy to age and lose efficacy; and the periphery of decorative board is sealed through the bubble cotton only, and the leakproofness effect is relatively poor, and when going under high-speed or heavy rain weather, a large amount of rivers flow into between radar decorative board and the automobile body main part, and the bubble cotton becomes invalid easily, and has the risk of getting into the interior driver's cabin of car after long-term bubble water.

Based on this, the lidar trim panel structure assembly 100 provided herein addresses the above-described issues. As shown in fig. 1 to 3, the laser radar decorative board structure assembly 100 is fixedly mounted on a roof sheet metal 102 for covering and mounting a laser radar 101, the laser radar decorative board structure assembly 100 includes a body 10, foam 20 and a first sealing member 30, the body 10 is used for mounting the laser radar 101 and for abutting against the roof sheet metal 102; the foam 20 is fixed on one side of the body 10 facing the laser radar 101, and surrounds the body 10 for one circle, and enables the body 10 to be abutted against the roof sheet metal 102 through the foam 20 in a sealing manner. The first sealing member 30 surrounds the outer peripheral side of the foam 20 (i.e. the first sealing member 30 is located on the side of the foam 20 away from the laser radar 101), and the first sealing member 30 is in sealing connection with the body 10; wherein the side of the first seal 30 remote from the body 10 is adapted to seal against the roof panel 102.

It should be noted that the foam 20 is a soft material with good sealing performance, but the foam 20 becomes hard after a long period of soaking in water, resulting in a decrease in sealing performance. In the present application, the first sealing member 30 is arranged and surrounds the periphery of the foam 20, so as to encircle the foam 20 integrally; thus, through the blocking effect of the first sealing element 30 on the rainwater, the rainwater can be prevented from contacting the foam 20, even if a small amount of rainwater passes over the first sealing element 30 to contact the foam 20, the foam 20 is difficult to fail, and the tightness of the laser radar decorative plate structure assembly 100 is effectively improved. That is, here, at least two seals are formed by the first seal 30 and the foam 20, so that the protection of the lidar 101 is improved. Meanwhile, the body 10 is not directly erected on glass, but is abutted against the roof sheet metal 102 through the foam 20 and the first sealing piece 30 in a multiple sealing way, so that the sealing is more reliable.

Here, the roof sheet metal 102 may be a panel member, a sheet metal member, or the like of an automobile body.

In one embodiment, as shown in fig. 3, 4, 6 and 7, the body 10 includes an outer plate 11 and a trim frame 12, the trim frame 12 is located at the inner side of the outer plate 11, foam 20 is mounted on the trim frame 12, and the first seal member 30 is connected with the trim frame 12 in a sealing manner. Here, the outer panel 11 is provided with a smooth surface on a side away from the trim panel skeleton 12, and has an effect of improving the appearance and reducing wind resistance of the entire vehicle. The plaque skeleton 12 is made of hard plastic or plastic.

As shown in fig. 6 to 9, in an embodiment, a mounting groove 13 and a mounting hole 14 are formed on the body 10, the mounting groove 13 being used for mounting the lidar 101; the mounting hole 14 communicates with the mounting groove 13 and is exposed by the laser radar 101, so that the laser radar 101 emits laser light through the mounting hole 14 to measure various data (distance, environmental information, etc.). The lidar decorative plate structure assembly 100 further comprises a second sealing member 40, wherein the second sealing member 40 is arranged around the circumference of the mounting hole 14 and is used for sealing a gap between the body 10 and the lidar 101. Thus, rainwater, dust, or the like is prevented from entering the mounting groove 13 from the gap between the lidar 101 and the seal body 10.

Preferably, the body 10 is integrally recessed to form the mounting groove 13, that is, the outer panel 11 and the trim skeleton 12 are recessed in one direction at the same time at a predetermined position.

As shown in fig. 9, the second seal 40 includes a first portion 41 and a second portion 42, the first portion 41 being located between the outer panel 11 and the trim panel skeleton 12, thereby sealing a gap between the outer panel 11 and the trim panel skeleton 12; the second portion 42 is located at the aperture of the mounting hole 14 and is exposed to the outside of the body 10 for abutment with the lidar 101, thereby effecting a seal against the mounting of the lidar 101.

Here, as shown in fig. 9 and 10, when the lidar 101 is mounted into the mounting groove 13, the end of the lidar 101 facing the mounting hole 14 is simultaneously brought into abutment with the trim skeleton 12, the second portion 42 of the second seal 40. In this way, while the lidar 101 is supported by the trim skeleton 12, the second portion 42 is also sealed, which can prevent collapse, cause seal failure, and enhance seal to prevent inflow of flowing water.

Preferably, along the axial direction of the mounting hole 14, the second portion 42 is disposed protruding from the tile skeleton 12 toward the side of the mounting groove 13, or the side of the second portion 42 facing the mounting groove 13 is flush with the surface of the tile skeleton 12, so as to facilitate the formation of a seal with the lidar 101.

Further, a circle of flange 101a is circumferentially arranged at one end of the laser radar 101 facing the mounting hole 14, and the flange 101a forms sealing abutment with the plaque skeleton 12 and the second portion 42 along with the mounting of the laser radar 101.

In the present embodiment, the second seal 40 is provided as rubber or silicone. It should be explained that rubber or silica gel has the advantages of being insoluble in water and aging resistant, and is not easy to lose effectiveness after contacting rainwater for a long time, thereby protecting the foam 20 from being soaked by rainwater. Of course, the second sealing member 40 may be made of other materials as long as the sealing requirement is satisfied.

As shown in fig. 7, the mounting groove 13 is provided with a first limiting member 15, the mounting hole 14 is provided with a second limiting member 16, and the first limiting member 15 and the second limiting member 16 are used for limiting the laser radar 101.

So, first locating part 15 and second locating part 16 can form the ascending location of different directions to laser radar 101 to better fixed laser radar 101 prevents that laser radar 101 from rocking at the in-process that the car was gone, guarantees laser radar 101 normal operating.

Specifically, the first limiting member 15 is set to be an elastic sheet auxiliary limiting structure or a buckle, and the second limiting member 16 is set to be a strip bending bracket. The second stopper 16 protrudes toward the inside of the mounting groove 13, thereby protruding the wall surface of the mounting groove 13.

Further, a positioning seat 17 is further formed in the mounting groove 13, the positioning seat 17 is further provided with a mounting hole 171, and the positioning seat 17 is provided with a positioning protrusion 172. Wherein the positioning protrusions 172 are used to position the lidar 101 when it is mounted, and the mounting holes 171 are used for passing fasteners to fix the lidar 101 into the mounting groove 13. Here, the fastener may be a bolt, a screw, or the like.

As shown in fig. 2 to 5, at least two sealing portions 31 are provided on the side of the first seal member 30 away from the body 10, and the at least two sealing portions 31 are used for sealing against the roof sheet metal 102. Here, the provision of at least two sealing portions 31 may enable the first sealing member 30 to form a plurality of sealing contact points with the roof sheet metal 102, thereby further improving the waterproof performance and sealing performance of the lidar decorative plate structure assembly 100 as a whole.

Here, the number of the sealing parts 31 may be set to two, three, four, or the like. The first seal 30 may be any one of silicone or rubber.
