Description
Technical Field
[0001] The present invention relates to the field of automobile supplies, and in particular to a vehicle-mounted laser radar with a dust-proof mechanism and a use method thereof. Background Art
[0002] As we all know, LiDAR is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of a target. Its working principle is to transmit a detection signal to the target, and then compare the received signal reflected from the target with the transmitted signal. After appropriate processing, the relevant information of the target can be obtained.
[0003] At present, in order to timely sense the potential safety hazards in the driving of the car, LiDAR technology has begun to be widely used in cars; however, the existing on-board LiDAR has the following two problems when in use:
[0004] 1. When the car is in a stationary state, the laser radar does not need to be used. However, due to the lack of dust-proof function settings for the on-board laser radar when not in use, the surface of the laser radar will be contaminated with dust when the car is parked for a long time, which will affect the detection effect when it is used again. In addition, since the laser radar is usually installed on the top of the car, it is not convenient to manually remove dust from the laser radar;
[0005] Second, the laser radar in the prior art is not easy to quickly disassemble and assemble on the top of the car, which results in an inconvenient operation process when the laser radar needs to be repaired or replaced after a failure.
[0006] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may include information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention
[0007] The object of the present invention is to provide a vehicle-mounted laser radar with an anti-dust mechanism and a method of using the same, so as to solve the problems raised in the above-mentioned background technology.
[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a vehicle-mounted laser radar with a dust-proof mechanism, comprising: a laser radar body, a disassembly and assembly mechanism, and a dust-proof mechanism;
[0009] Slots are provided on both sides of the laser radar body;
[0010] The disassembly and assembly mechanism comprises a base, the top of the base is fixedly connected with a block, the inside of the block is rotatably connected with a bidirectional screw rod, one end of the bidirectional screw rod is fixedly connected with a rod body, one end of the rod body is fixedly connected with a stopper, a torsion spring is sleeved on the rod body, the two ends of the torsion spring are respectively fixedly connected with the block body and the stopper, two clamping plates are threadedly sleeved on the bidirectional screw rod, the bottoms of the two clamping plates are movably connected with the base, and the two clamping plates are inserted into the inside of the slot;
[0011] The dustproof mechanism includes a dust cover, a plate body and a through slot opened inside the base, one side of the dust cover is hinged to the base, the other side of the dust cover is fixedly connected to a spring, one end of the spring is fixedly connected to the base, a motor is fixedly installed on one side of the plate body, and a winding roller is rotatably connected to the other side of the plate body, the output shaft of the motor is fixedly connected to the winding roller, a pull rope is wound on the winding roller, one end of the pull rope passes through the through slot and is fixedly connected to the dust cover.
[0012] By adopting the above technical solution, when the laser radar body is placed on the base, the stopper can be loosened to allow the rod body to drive the bidirectional lead screw to rotate clockwise under the action of the torsion spring, so that the two clamping plates can move closer to each other on the base under the action of the bidirectional lead screw, and then the two clamping plates can be inserted into the slot to fix the laser radar body; when the laser radar body needs to be disassembled, the stopper can drive the bidirectional lead screw to rotate counterclockwise, so that the two clamping plates can move away from each other on the base, and then the clamping plates can be pulled out of the slot. The laser radar body can be removed; in addition, when the laser radar body needs to be used, the external controller can start the motor, so that the motor drives the winding roller to rotate, and then the winding roller can reel in the pull rope, so that the dust cover can rotate under the action of the pull rope, so that the dust cover can be opened from the base, and the laser radar body can be used normally; when the laser radar body needs to be dust-proof when not in use, the motor can drive the winding roller to rotate in the opposite direction, so that the pull rope loses the tensioning force on the dust cover, and the dust cover can cover the top of the base under the resetting action of the spring.
[0013] Preferably, the bidirectional screw rod is symmetrically provided with two opposite threads, and the two clamping plates are respectively threadedly mounted on the two opposite threads.
[0014] By adopting the above technical solution, after the bidirectional screw rod rotates clockwise or counterclockwise, the two clamping plates can move closer to or away from each other.
[0015] Preferably, a slide groove is provided on the top of the base, and the inner side wall of the slide groove is slidably connected to the clamping plate.
[0016] By adopting the above technical solution, the splint can be made more stable during the movement.
[0017] Preferably, a groove is provided on the top of the base, and a rubber pad is fixedly connected to one side of the dust cover.
[0018] By adopting the above technical solution, after the dust cover covers the top of the base, the rubber pad can be inserted into the groove, so that the elastic force of the rubber pad can tighten the inner wall of the groove, thereby allowing the dust cover to be positioned after closing.
[0019] Preferably, a handle is fixedly connected to a side of the stopper away from the rod body.
[0020] By adopting the above technical solution, it is possible to easily rotate the stopper, thereby facilitating the rotation of the bidirectional screw rod.
[0021] Preferably, a hollow groove is provided on one side of the dust cover.
[0022] By adopting the above technical solution, it is possible to avoid the rod body blocking the closing action of the dust cover.

[0024] By adopting the above technical solution, the winding roller can be made to rotate more smoothly.
[0025] In addition, the present invention also provides a method for using a vehicle-mounted laser radar with an anti-dust mechanism, comprising the following steps:
[0026] Step 1: Fix the base to the roof by tightening the screws inside the car, and then use the handle to turn the block counterclockwise so that the block drives the bidirectional screw rod to rotate counterclockwise through the rod body, and the two splints can move away from each other;
[0027] Step 2: Place the laser radar body between the two clamping plates, and loosen the handle so that the block drives the rod body to rotate clockwise under the reset action of the torsion spring, so that the two-way screw rod drives the two clamping plates to approach each other after clockwise rotation, and the two clamping plates are respectively inserted into the slots on both sides of the laser radar body, so that the position of the laser radar body is fixed;
[0028] Step 3: When the laser radar body is in normal use, the motor is started to drive the winding roller to reel in the pull rope, and the dust cover is driven by the pull rope to rotate, so that the dust cover maintains a vertical relationship with the base under the action of the pull rope;
[0029] Step 4. When the car is parked, the laser radar body is not needed. The motor drives the winding roller to loosen the winding of the pull rope, so that the dust cover covers the top of the base under the contraction force of the spring, preventing dust from coming into contact with the laser radar body.
[0030] Preferably, in step three, in order to facilitate the opening and closing operation of the dust cover inside the car, the electric control input end of the motor is electrically connected to the electric control output end of the controller inside the car.
[0031] In summary, the present application includes at least one of the following beneficial technical effects:
[0032] The vehicle-mounted laser radar with a dust-proof mechanism and the use method thereof, through the provision of a disassembly and assembly mechanism and a dust-proof mechanism, can drive the two clamping plates to enter or move out of the slots of the laser radar body after the bidirectional lead screw rotates clockwise or counterclockwise, and the dust cover can be opened after the motor drives the winding roller to wind up the pull rope; through the above provision, the vehicle-mounted laser radar that is not in use can be dust-proofed, and it is also more convenient to quickly disassemble and assemble the vehicle-mounted laser radar on the car.
