[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a focus-free miniature lidar.

[0029] Example 1:

[0030] Combination Figure 1-5 As shown, the present invention provides a focus-free small lidar, including a detection mechanism 100 and an anti-detachment mechanism 200. The detection mechanism 100 includes a car body 110, a radar body 120 inserted into the car body 110, and a limiting block 130 that abuts against the rear side of the car body 110 and is connected to the radar body 120.

[0031] The anti-detachment mechanism 200 includes a lock housing 210 movably sleeved on the rear end of the radar body 120 and bonded to the rear side of the vehicle body 110, a limiting block 220 disposed inside the lock housing 210 and connected to the radar body 120, a locking channel 230 opened inside the lock housing 210 and adapted to be inserted into the limiting block 220, and a rubber ball rod 240 installed inside the locking channel 230, wherein the rubber ball rod 240 is interference-fitted with the limiting block 220.

[0032] Furthermore, the second limiting block 220 is located on the rear side of the first limiting block 130. Both are made of plastic. The plastic limiting blocks 130 and 220 are lightweight and will not put a load on the radar body 120. Moreover, the hard plastic can also provide a firm locking function.

[0033] Furthermore, the locking channel 230 is composed of two parts: an arc-shaped groove and a rectangular groove. The rectangular groove is located in front of the arc-shaped groove. The arc-shaped groove is connected to the interior of the large ring groove 300 through the rectangular groove. The distance between the second limiting block 220 and the first limiting block 130 is equal to the length of the rectangular groove. The shape and size design of the locking channel 230 enable the second limiting block 220 to be firmly locked inside the lock housing 210, thus ensuring the secure installation of the radar body 120.

[0034] Furthermore, the rubber ball rod 240 is located inside the arc-shaped groove. The rubber ball rod 240 consists of a short shaft and a ball. The ball is located at the top of the short shaft and its diameter is larger than that of the short shaft. The shape design of the rubber ball rod 240 enables it to firmly fix the limiting block 220 and prevent the limiting block 220 from loosening.

[0035] Example 2:

[0036] Combination Figure 4-5 As shown, based on Embodiment 1, the front end of the lock housing 210 is provided with a large annular groove 300, and the limiting block 130 is movably disposed inside the large annular groove 300. The large annular groove 300 is provided so that the radar body 120 passing through the car body 110 can rotate, ensuring that the radar body 120 can be firmly engaged with the car body 110.

[0037] Example 3:

[0038] Combination Figure 1 As shown in the above embodiment, a rubber pad 400 is sleeved on the front end of the lock housing 210. The front side of the rubber pad 400 is in contact with the rear side of the car body 110. The rubber pad 400 can reduce the probability of dust entering the contact surface between the car body 110 and the lock housing 210, and ensure the strong adhesion of the lock housing 210.

[0039] The working principle and usage process of this utility model are as follows: When this device is put into actual use, a vehicle-mounted radar with a focus-free function is purchased from the market. After confirming that the lock housing 210 is bonded to the inner wall of the car body 110, the radar body 120 is passed through the car body 110 and then enters the lock housing 210. Then, the radar body 120 is rotated so that the first limiting block 130 is pressed against the rear side of the car body 110, and the second limiting block 220 is connected to the rubber ball rod 240. With double reinforcement, the radar body 120 is effectively prevented from falling off, and the safety of the radar body 120 is improved.
