It is understood that the shape of the coupling groove 532 may be a groove having a square, circular or other shape, as long as it is satisfied that the fixing groove 532 can be coupled with the ultrasonic sensor to fix the ultrasonic sensor at a designated position.

Specifically, the first fixing rods 533 are four short rods, which are respectively disposed above two ends of the fixing case 53 and fixedly connected to the reflection plate 52, so as to fix the reflection plate 52 at a predetermined position. When the fixing case 53 is mounted, it is fixed, and after the fixing is completed, since the reflection plate 52 is fixedly connected to the first fixing rod 533, the reflection plate 52 is also fixed at a predetermined position. It should be understood that the connection manner of the first fixing rod 533 and the fixing shell 53 may be a detachable fit, a welding, an integral connection or other connection manners, as long as the first fixing rod 533 and the fixing shell are capable of being connected together

The stationary housing 53 is firmly connected. Of course, the connection manner between the first fixing rod 533 and the reflection plate 52 is not particularly limited in this embodiment, as long as the reflection plate 52 can be stably connected to the first fixing rod 533.

Specifically, the second fixing plate 534 is four short rods, which are respectively disposed below and connected to two ends of the fixing housing 53, and are used to position the fixing housing 53 and the reflection plate 52. When the fixing shell 53 is installed, the fixing shell 53 is placed into the protective shell 51, and at this time, the second fixing rod 534 positions the fixing shell 53 and vertically places the fixing shell 53 in the protective shell 51; after the placement, the second fixing bars 534 contact both sides of the reflection plate 52 and fix them at a designated position. It is understood that the connection manner of the second fixing rod 534 and the fixing shell 53 may be a detachable fit, a welding, an integral connection, or other connection manner, as long as the second fixing rod 534 can be stably connected with the fixing shell 53.
