When the ranging circuit board is assembled, the hole sites of the ranging circuit board are required to be aligned with the hole sites on the mounting bracket, and screws are sequentially used to penetrate through the hole sites of the ranging circuit board and are locked on the corresponding hole sites of the mounting bracket. The assembly process of the ranging circuit board is complex, and the assembly efficiency of the ranging circuit board is low.

In order to solve the above-mentioned problems, an embodiment of the present application provides a ranging module, referring to fig. 1-4, which includes a transmitting unit 1, a receiving unit 2, a ranging circuit board 3 and a mounting bracket 4. At least one of the transmitting unit 1 and the receiving unit 2 is electrically connected to the ranging circuit board 3. The mounting bracket 4 includes a limit structure 43, and the ranging circuit board 3 is mounted on the mounting bracket 4 through the limit structure 43, and the mounting bracket 4 forms a transmitting path 41 corresponding to the transmitting unit 1 and a receiving path 42 corresponding to the receiving unit 2. Specifically, the ranging circuit board 3 may be a transmitting circuit board electrically connected only to the transmitting unit 1, may be a receiving circuit board electrically connected only to the receiving unit 2, or may be electrically connected to both the transmitting unit 1 and the receiving unit 2.

In the embodiment of the present application, at least one of the transmitting unit 1 and the receiving unit 2 is electrically connected to the ranging circuit board 3, so that the ranging circuit board 3 can control the transmitting unit 1 to transmit light or the receiving unit 2 to receive light. The ranging circuit board 3 is mounted on the mounting bracket 4, and the light emitted from the emitting unit 1 may be emitted through the emitting path 41, and the receiving unit 2 may receive the light through the receiving path 42. Be equipped with limit structure 43 on the installing support 4, range finding circuit board 3 can be installed on installing support 4 through limit structure 43, compares the prior art and passes through the spacing mode of range finding circuit board 3 of screw, has simplified the assembly process between installing support 4 and the range finding circuit board 3, has improved the assembly efficiency of range finding circuit board 3.

Wherein the transmitting unit 1 and the receiving unit 2 may be disposed at intervals on a side of the ranging circuit board 3 facing the mounting bracket 4. By way of example, a laser assembly may be used as the transmitting unit 1 and an image sensor assembly as the receiving unit 2. The laser emitted by the laser irradiates the surrounding object and is reflected by the surrounding object, and the image sensor assembly can acquire the distance between the ranging module and the surrounding object according to the time from the emission to the reflection of the laser by receiving the laser reflected by the surrounding object.

This structure can avoid the screw from directly locking the ranging circuit board 3, compared with the case where the ranging circuit board 3 is pre-fixed on the mounting bracket 4 by the screw. Compared with the mode that the ranging circuit board 3 is fixed on the mounting bracket 4 directly through dispensing without pre-fixing, the range of motion of the ranging circuit board 3 can be limited through the limiting structure 43, and the distance between the ranging circuit board 3 and the mounting bracket 4 is conveniently set by workers, so that the assembly efficiency of the ranging circuit board 3 is improved.

The limiting portion 4311 is a protrusion of each hook 431 away from one end of the mounting bracket 4, and the distance measuring circuit board 3 can be prevented from being separated from the mounting bracket 4 by the limiting portion 4311. The specific number of hooks 431 is not limited, and one skilled in the art can set the number according to actual needs.

Illustratively, the mounting bracket 4 and the limiting structure 43 may be made of a polymer material, and when the ranging circuit board 3 is assembled, the limiting structure 43 may be deformed by pushing the hook 431 against the side end of the ranging circuit board 3.

For example, the number of hooks 431 is four, and correspondingly, notches 31 are respectively arranged at four corners of the ranging circuit board 3, and the four hooks 431 extend into the four notches 31 in a one-to-one correspondence manner. It will be appreciated that, after the side end of the ranging circuit board 3 extends into the corresponding clamping space 432, the ranging circuit board 3 may be limited on the mounting bracket 4.
