[0002] LiDAR is a high-precision, high-resolution radar system primarily composed of a laser transmitter, an optical receiver, a turntable, and an information processing system. The laser transmitter converts electrical pulses into light pulses and transmits them; the optical receiver receives light pulses reflected from the target and converts them back into electrical pulses; the turntable changes the direction of the laser beam to scan the target; and the information processing system processes the received signals to extract relevant information about the target.

[0003] At present, laser radars are usually installed in protective boxes for use. The laser radar anti-interference protective box is a device used to protect the laser radar from external interference and damage. It has anti-crosstalk and anti-interference functions, which will improve the performance of the laser radar. However, the existing protective box needs to be manually installed with screws, which is labor-intensive and has low work efficiency.

[0007] It also includes: a side plate arranged above the bottom plate, wherein the inner surface wall of the side plate is provided with a groove, a fixing plate is detachably installed inside the groove, and a laser radar is detachably installed on the fixing plate;

[0008] The cover plate installed above the side panel is disassembled, and a locking mechanism is provided at the bottom surface of the cover plate near the four corners. The locking mechanism includes a connecting rod fixedly connected to the cover plate, and a fixing sleeve is fixedly provided at the end of the connecting rod away from the cover plate, a connecting piece is fixedly provided on the inner surface of the fixing sleeve, and a locking block is integrally provided at the end of the connecting piece away from the fixing sleeve. Limiting holes compatible with the locking mechanism are provided near the four corners on the top surface of the side panel, and the limiting holes are used to firmly install the locking mechanism.

[0009] Furthermore, a limiting ring is fixedly provided inside the limiting hole along the horizontal direction, and the limiting ring is adapted to the engaging block.

[0010] Through the above structural design, the limiting ring is used to engage with the locking block to connect the cover plate and the side plate, thereby sealing the laser radar, thereby improving the anti-crosstalk and anti-interference performance of the laser radar.

[0011] Furthermore, a first inclined surface is provided on the lower side of the engaging block, and a second inclined surface is provided on the upper side of the limiting ring, and the second inclined surface is adapted to the first inclined surface.

[0012] Through the above structural design, the first inclined surface and the second inclined surface are utilized to facilitate the locking block to smoothly pass through the limiting ring when the locking mechanism is inserted into the limiting hole.

[0013] Furthermore, a sealing plate is fixedly provided on the bottom surface of the covering plate, and the sealing plate is inserted into the groove and fits with the upper end surface of the fixing plate.

[0014] Through the above structural design, the sealing plate is inserted into the groove to improve the sealing inside the side panel, preventing external debris from entering, thereby increasing the service life of the laser radar.

[0015] Furthermore, a clamping plate is fixedly provided on the top surface of the base plate, and a sponge plate for protecting the laser radar is fixedly provided on one side of the clamping plate.

[0016] Through the above structural design, the sponge board can be easily installed by using the clamping plate, the sponge board can be used to firmly clamp the laser radar, and the impact resistance of the laser radar can be improved, thereby improving the safety of the laser radar.

[0017] Furthermore, a support plate is fixedly provided on the inner surface of the side panel, and a cooling fan for cooling the laser radar is installed on the support plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the anti-crosstalk and anti-interference device for laser radar facilitates the use of a protective box to seal the laser radar, thereby improving the anti-crosstalk and anti-interference performance of the laser radar, and the protective box is easy to install and has high work efficiency.

[0021] 2. A locking mechanism and a limiting hole are provided. During use, after the laser radar is installed, the locking mechanism is aligned with the limiting hole and inserted. When the first inclined surface contacts the second inclined surface, the limiting ring will squeeze the locking block, and the locking block will shrink inward.

[0030] Through the above-mentioned structural design, when in use, the fixing plate 12 with the laser radar 13 installed is inserted into the groove 11, and then the cover plate 14 is firmly installed using the snap-fit mechanism 2. The bottom plate 1, the side plate 10 and the cover plate 14 will be assembled into an anti-crosstalk and anti-interference protection box containing an electromagnetic shielding layer inside, thereby improving the anti-crosstalk and anti-interference performance of the laser radar 13.

[0031] The locking mechanism 2 includes a connecting rod 20 fixedly connected to the covering plate 14, and a fixing sleeve 21 is fixedly provided at the end of the connecting rod 20 away from the covering plate 14, a connecting member 22 is fixedly provided on the inner surface of the fixing sleeve 21, and a locking block 23 is integrally provided at the end of the connecting member 22 away from the fixing sleeve 21, and the top surface of the side panel 10 is provided with limiting holes 100 adapted to the locking mechanism 2 near the four corners, and the limiting holes 100 are used to firmly install the locking mechanism 2, and a limiting ring 101 is fixedly provided in the horizontal direction inside the limiting hole 100, and the limiting ring 101 is adapted to the locking block 23, and a first inclined surface 24 is provided on the lower side of the locking block 23, and a second inclined surface 102 is provided on the upper side of the limiting ring 101, and the second inclined surface 102 is adapted to the first inclined surface 24.
