[0002] LiDAR is a radar system that uses laser beams to detect target characteristics such as position and speed. Its operating principle is essentially the same as that of microwave radar. It transmits a detection signal (laser beam) toward the target, then compares the received signal reflected from the target (target echo) with the detection signal. After appropriate processing, it can obtain relevant target information such as target distance, direction, altitude, speed, attitude, and even shape.

[0003] In related technologies, common laser ranging radars are exposed to the air when in use without any explosion-proof protection measures. When unattended, the laser ranging radar is easily damaged by impact, which is not conducive to achieving high-safety use. Utility Model Content

[0028] This application proposes a laser ranging radar explosion-proof housing 100, which is used for the installation and fixation of the laser ranging radar on the target product. Figures 1 to 3 In an embodiment of the present application, the laser ranging radar explosion-proof housing 100 includes a shell 10 for being fixedly connected to a fixing bracket of a target product.

[0029] It is understood that target products employing laser ranging radars typically have various mounting brackets for mounting various functional modules. The laser ranging radar explosion-proof housing 100 provided herein can be mounted and fixed to at least one of these mounting brackets, thereby allowing the laser ranging radar to be mounted and fixed via the laser ranging radar explosion-proof housing 100. Specifically, in some examples, the outer surface of the housing 10 is provided with a plurality of threaded holes for threaded connection with the mounting brackets.

[0030] The housing 10 has a mounting cavity 13 for mounting and fixing the laser ranging radar. The housing 10 also has a first end face 121 and a second end face 111, which are arranged opposite each other. The first end face 121 has a transparent window for the laser beam to pass through, and the second end face 111 has a wire hole 112 that communicates with the mounting cavity 13. The wire hole 112 provided on the second end face 111 is used to pass the wires connected to the laser ranging radar. These wires are used to connect the laser ranging radar to external devices, provide power to the laser ranging radar, establish communication connections, etc.

[0031] The shape of the mounting cavity 13 is usually adapted to the outer contour of the laser ranging radar, wherein the laser ranging radar can be installed in the mounting cavity 13 by a detachable fixed connection, such as threaded connection or clip connection; the laser ranging radar can also be installed in the mounting cavity 13 by a non-detachable fixed connection, such as welding or riveting. Here, this application does not make specific restrictions.

[0032] In the operating principle of LiDAR, the LiDAR transmits a detection signal (a laser beam) to a target. The LiDAR then receives a signal reflected from the target, which is known as the target echo. The laser beam can pass through a transparent window, and of course, the target echo can also pass through the transparent window.

[0033] The laser ranging radar explosion-proof housing 100 provided in the present application, through the above-mentioned structural setting, can first be installed in the installation cavity 13 of its shell 10 through a detachable or non-detachable fixed connection method, and then its shell 10 is fixedly installed on the fixed bracket of the target product, so that the laser ranging radar can be fixedly installed on the fixed bracket of the target product through the shell 10. In this way, during use, the laser ranging radar can be protected by the shell 10 to prevent the laser ranging radar from being directly exposed to the air. When unattended, the laser ranging radar can be prevented from being damaged by impact, thereby improving safety. In addition, the structural setting of the transparent window and the wire hole 112 can ensure that the shell 10 provides closed protection for the laser ranging radar while ensuring the normal operation of the laser ranging radar.

[0034] In some examples, such as Figure 1 and Figure 3 As shown, the housing 10 includes a main body 11 and a cover assembly 12. The main body 11 is recessed with a mounting groove. The cover assembly 12 is connected to the main body 11 to cover the notch of the mounting groove to form a mounting cavity 13. The first end surface 121 is provided on the cover assembly 12, and the second end surface 111 is provided on the side of the main body 11 away from the cover assembly 12. This arrangement is intended to improve the installation efficiency of the laser ranging radar in the mounting cavity 13.

[0035] In some examples, such as Figure 1 and Figure 3 As shown, the cover assembly 12 is detachably connected to the main body 11. This arrangement is intended to facilitate the subsequent opening of the installation cavity 13, thereby facilitating the maintenance and repair of the laser ranging radar.

[0036] In some examples, such as Figure 1 and Figure 3 As shown, the peripheral wall of the installation groove is provided with a first internal thread, and the cover assembly 12 is provided with a first external thread threadedly connected to the first internal thread. Such a setting is intended to facilitate opening the installation cavity 13 while improving the sealing inside the installation cavity 13.

[0037] In some examples, the main body 11 is provided with a slot, and the cover assembly 12 is provided with a buckle that engages with the slot. This arrangement is intended to further facilitate the subsequent opening of the installation cavity 13.

[0038] In some examples, one side of the cover assembly 12 is pivotally connected to the main body 11. The cover assembly 12 rotates relative to the main body 11 to cover or open the notch of the mounting slot. This arrangement is intended to facilitate later opening of the mounting cavity 13, thereby facilitating maintenance and repair of the laser ranging radar.

[0039] In some examples, such as Figure 1 and Figure 3 As shown, the cover assembly 12 includes a cover 122 and explosion-proof glass 123. The cover 122 has a through hole 1221. The explosion-proof glass 123 is fixed to the cover 122 and covers the through hole 1221 to form a transparent window. This arrangement is intended to further improve the safety of the laser ranging radar explosion-proof housing 100.

[0040] In some examples, such as Figure 1 and Figure 3 As shown, an annular connecting tube 1222 is protruding from the side of the cover plate 122 away from the first end face 121, and the annular connecting tube 1222 is wrapped around the through hole 1221 to form an annular step surface 1223 on the side of the cover plate 122 away from the first end face 121. The explosion-proof glass 123 is accommodated in the annular connecting tube 1222 and abuts against the annular step surface 1223. The cover plate assembly 12 also includes an annular pressure plate 124, which is fixedly installed in the annular connecting tube 1222 to limit the explosion-proof glass 123 from detaching from the annular connecting tube 1222.

[0041] This configuration is intended to facilitate the assembly of the cover assembly 12 , thereby improving the production efficiency of the laser ranging radar explosion-proof housing 100 .

[0042] In combination with the above-mentioned cover plate assembly 12 , a first external thread connected to the first internal thread is provided. The first external thread is provided on the outer peripheral side of the annular connecting tube 1222 .

[0043] In some examples, such as Figure 1 and Figure 3 As shown, the annular connecting tube 1222 is provided with a second internal thread, and the annular pressing plate 124 is provided with a second external thread connected to the second internal thread. This arrangement is intended to facilitate the assembly of the cover assembly 12 while improving the sealing performance of the installation cavity 13.

[0044] In some examples, such as Figure 2 As shown, the laser ranging radar explosion-proof housing 100 further includes an explosion-proof cable gland 20, which is fixedly mounted on the outside of the wire hole 112; or the laser ranging radar explosion-proof housing 100 further includes an explosion-proof plug, which is fixedly mounted on the outside of the wire hole 112. This arrangement is intended to further improve the safety of the laser ranging radar explosion-proof housing 100.
