Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 and 2, a lidar seal structure may include a first seal 1 and a second seal 2. The first seal member 1 and the second seal member 2 are detachably fitted together for sealingly mounting the lidar main body 3 therein such that the lidar exposes only the laser light outlet port 31, the lens light-receiving port 31, and the external connection port 23. In the illustrated embodiment, the first seal member 1 and the second seal member 2 are of an upper-lower structure. It should be understood that it may also take a side-to-side configuration. The first sealing member (upper sealing member) 1 sealingly covers an upper exposed portion of the laser radar body 3, such as a pulley or the like, and the second sealing member (lower sealing member) 2 sealingly encloses a lower exposed portion of the laser radar body 3, such as a motor, a circuit board, or the like. Therefore, the laser radar sealing structure can carry out sealed protection on exposed external structural components of laser radars such as a circuit board, a motor, a belt pulley and the like, not only beautifies the appearance, but also prolongs the service life of the laser radar.

The laser radar sealing structure is further described below by taking the upper and lower structures as examples. Preferably, the second seal (lower seal) 2 has a flat bottom surface, so the lidar seal structure can act as a lidar mount so that the lidar can be operated directly horizontally on a flat surface without the aid of any support posts.

In the embodiment shown, the first seal 1 and the second seal 2 are snap fitted together. It should be understood that it may also be assembled by means of threads or welding, etc. Specifically, the outer wall of the first sealing element 1 is provided with an elastic buckle 11 extending downwards, and the elastic buckle 11 comprises an elongated main body 111 and an outwardly protruding hook-shaped part 112 arranged on the lower end of the elongated main body 111; the outer wall of the second sealing element 2 is provided with a clamping groove 21, the clamping groove 21 is of a box-shaped structure with an opening at the upper end, and the outer wall of the clamping groove 21 is provided with a strip-shaped hole 211. During assembly, the elastic buckle 11 is inserted into the clamping groove 12 and clamped in the strip-shaped hole 121 through the hook-shaped part 112 to realize fixed connection; when detaching, the hook-shaped part 112 is pressed inward to be disengaged from the strip-shaped hole 121, and the first sealing member 1 and the second sealing member 2 can be separated.

For convenient installation, the laser radar main body 3 is provided with a plurality of fixing columns 34, and each fixing column 34 is provided with a screw hole 341. In this embodiment, the number of the fixing posts 34 is three, one of which is at one end of the laser radar main body 3, and the other two are at the other end of the laser radar main body 3, so as to form an isosceles triangle. Upper seal member 1 is provided with a plurality (3 shown) of fixing holes 12 aligned with screw holes 341, and lower seal member 2 is provided with a plurality (3 shown) of cylindrical cavities 22 for receiving fixing posts 34. When the laser radar sealing device is installed, the fixing column 34 of the laser radar main body 3 is inserted into the lower sealing element 2, then the upper sealing element 1 is sleeved on the laser radar main body 3, the fixing hole 12 is aligned to the screw hole 341, and finally the fixing is performed through screw tightening.

Preferably, the first sealing element 1 and the second sealing element 2 can be both formed by injection molding of an ABS material, so that the lidar sealing structure has sufficient strength, avoids damage, prolongs the service life, and is aesthetically pleasing.
