Description

Technical Field

[0001] The utility model relates to the technical field of laser radar, in particular to a safety-type laser scanning sensor shock absorption device. Background Art

[0002] With the rapid development of laser scanning technology, laser scanning sensors are widely used in various fields, especially in the widespread use of intelligent devices. For example, laser scanning sensors are used in smart factories, intelligent transportation, autonomous driving, and smart devices. Laser scanning sensors scan external objects, collect physical data, and feed it back to the host computer for analysis, thereby making a series of judgments and realizing the intelligentization of mechanical equipment. Laser scanning sensors must operate smoothly, be unaffected by external equipment vibration, and be resistant to damage from impact to ensure normal function.

[0003] The existing patent with announcement number CN217561737U proposes a safety laser scanning sensor shock absorption device. The shock absorption device is installed in a semi-enclosed cover of the anti-collision shield by setting a safety laser scanning sensor and a shock absorption structure. The safety laser scanning sensor is laterally installed and connected to the shock absorption plate of the shock absorption structure. The shock absorption plate is installed on the side of the opening of the "J" structure of the anti-collision shield through screws and shock absorption springs. The shock absorption plate and the side plate of the anti-collision shield are connected by fastening screws and shock absorption springs.

[0004] However, the above-mentioned shock-absorbing device has a poor shock-absorbing and buffering effect on the laser scanner when it is working. The laser scanner will still vibrate during use and cannot run smoothly, which can easily cause the laser scanner to be damaged by collision, reducing the protection of the laser scanner. In response to the above problems, we proposed a safety-type laser scanning sensor shock-absorbing device for improvement and upgrading. Utility Model Content

[0026] Preferably, the upper end surfaces of the first damping rod 12 and the second damping rod 14 are both fittedly connected to the support plate 3, and the upper end surface of the support plate 3 is provided with a scanning device 2, which is convenient for stably supporting the laser scanning sensor, and the cylinder 6 is fixedly arranged inside the base 4 and there are two cylinders 6, one end of the cylinder 6 is fixedly connected to the top plate 8 and one end of the top plate 8 is connected to the lower end surface of the bottom plate 9, which is convenient for supporting and moving the shock absorbing mechanism out, and sliding grooves 7 are provided on both sides of the inner wall of the base 4, and a slider 5 is fixedly provided on the outer wall of the support plate 3 and the slider 5 is slidably connected to the inside of the sliding groove 7, which is convenient for the base 4 to slide stably when moving.
