Description

Technical Field

[0001] This invention relates to the field of lidar mapping equipment, and in particular to shock-absorbing components for equipment storage and transportation. Background Technology

[0002] LiDAR (Light Detection and Ranging) surveying is a relatively new and revolutionary surveying method in my country's surveying and mapping field, playing an increasingly irreplaceable role in areas such as smart cities, intelligent transportation, power line inspection, forest surveys, and cultural relic protection. In engineering applications, LiDAR surveying equipment inevitably needs to be transported over long distances. Currently, the method of using rigid plastic boxes with embedded sponge or foam partitions often provides insufficient shock absorption. Since LiDAR measuring instruments are expensive and precision equipment, there is an urgent need for new shock-absorbing devices to protect the instruments, extend their lifespan, and ensure the accuracy of measurement results. Summary of the Invention

[0003] The purpose of this invention is to provide a vibration damping component for lidar mapping equipment, thereby improving the service life of the equipment and ensuring the stability of the accuracy of the results.

[0004] The present invention achieves the above objectives through the following technical solutions: A vibration damping component for a lidar mapping equipment includes a lifting mechanism for adjusting the height of the lidar mapping equipment, a fixed base, and a support mechanism for supporting the lidar mapping equipment. The fixed base is located above the support mechanism, and the lifting mechanism is located below the support mechanism. The component also includes a blocking mechanism for blocking vibration transmission to the lidar mapping equipment and a shock-absorbing mechanism for canceling and absorbing vibration. The blocking mechanism includes a blocking frame, a fixing groove, a sliding groove, and an electromagnet. The fixing groove is located on both sides of the blocking frame, the sliding groove is located in the middle of the inner wall of the blocking frame, and the electromagnet is located on the front and rear sides of the blocking frame. The shock-absorbing mechanism includes a shock-absorbing box, a spring plate, a bearing, a permanent magnet, and a positioning seat. The shock-absorbing box is located inside the blocking frame, the spring plate is located in the middle of the side of the shock-absorbing box, the positioning seat is located at the four corners of the shock-absorbing box, the permanent magnet is located on the positioning seat, and the bearing is located on the front and rear sides of the end of the spring plate. When the entire lidar experiences vibration during transportation, the shock-absorbing box will reciprocate in multiple directions within the barrier frame. As the shock-absorbing box moves, the four spring plates deform and drive the bearings at their ends to move within the slide groove, thereby counteracting the kinetic energy of the reciprocating movement of the shock-absorbing box. When the shock-absorbing box moves back and forth within the barrier frame, the magnetic strength of the four electromagnets on the front and back sides is controlled to attract the permanent magnets, thereby controlling the forward and backward movement distance of the shock-absorbing box and counteracting the tendency of the shock-absorbing box to move back and forth.

[0005] Preferably, the lifting mechanism includes a lifting seat and casters. The upper end of the lifting seat is disposed inside the fixed groove, and the casters are bolted to both sides of the bottom of the lifting seat.

[0006] With this configuration, the upper end of the lifting seat cooperates with the fixed groove, and the casters are used to support the lifting seat, thereby stabilizing and adjusting the surveying height and angle.

[0007] Preferably, the fixing seat is welded to the middle position of the top of the barrier frame, and the top of the fixing seat is provided with a threaded hole.

[0008] This configuration also allows the use of the mounting bracket at the top of the barrier frame to secure the lidar mapping equipment.

[0009] Preferably, the support mechanism includes a support plate, a pressure plate, shock-absorbing cotton, and a support spring. The support plate is disposed on the front side of the shock-absorbing box, the pressure plate is disposed between the shock-absorbing box and the lifting seat, the shock-absorbing cotton is disposed on the side of the pressure plate, and the support spring is disposed between the support plate and the pressure plate.

[0010] This configuration utilizes the support plate, the pressure plate, and the shock-absorbing cotton to enclose the front end of the shock-absorbing box and simultaneously support the laser radar mapping equipment stored therein.

[0011] Preferably, the rear end of the support plate is connected to one side of the shock-absorbing box via a hinge, and the front end of the support plate is connected to the other side of the shock-absorbing box via a latch.

[0012] This configuration utilizes the support mechanism to prevent the lidar mapping equipment from shaking within the shock-absorbing box.

[0013] Preferably, the support spring is welded to the support plate, the support spring is welded to the pressure plate, and the shock-absorbing cotton is bonded to the pressure plate.

[0014] With this configuration, the support spring is used to push the pressure plate and the shock-absorbing cotton to fix the lidar mapping equipment.

[0015] Preferably, the fixing groove is welded to the barrier frame, the sliding groove is welded to the barrier frame, and the electromagnet is fixedly connected to the barrier frame.

[0016] With this configuration, the bearing is supported by the groove on the inner side of the barrier frame, and the electromagnet is controlled to attract the permanent magnet.

[0017] Preferably, the spring plate is fixedly connected to the shock-absorbing box, the positioning seat is welded to the shock-absorbing box, and the permanent magnet is fixedly connected to the positioning seat.

[0018] With this configuration, the permanent magnet and the two electromagnets are used to alternately attract each other, thereby controlling the position of the shock-absorbing box inside the barrier frame.

[0019] Preferably, the inner wall of the shock-absorbing box is bonded with foam partitions.

[0020] This configuration utilizes the foam partitions on the inner wall of the shock-absorbing box to reduce vibration of the lidar equipment.

[0021] Preferably, the bearing is fixedly connected to the spring plate, and the spring plate is disposed inside the slide groove.

[0022] With this configuration, the bearing is used to support the end of the spring plate, and the deformation of the spring plate during shock absorption allows the bearing to move within the groove.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The arc-shaped spring plate on the outside of the shock-absorbing box is used as a support, and the bearing at the end of the spring plate moves in the slide groove. During this process, the deformation of the spring can effectively absorb the vibration. 2. By controlling the magnetism of four sets of electromagnets, the distance between the electromagnets and permanent magnets on the shock-absorbing box is changed, thereby causing the shock-absorbing box to produce a displacement in the opposite direction to the vibration amplitude, thus blocking the transmission of vibration.
