Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In an embodiment of the present invention, a collapsible energy-absorbing lidar mounting bracket is provided, as shown in fig. 1, including: the energy-absorbing radar device comprises a collapse frame 200, an energy-absorbing base 100 for mounting a laser radar 400 and a spring 300, wherein the collapse frame 200 is connected with the energy-absorbing base 100 in a sliding manner; the collapse frame 200 is of a concave structure, a first limiting bump 204 and a first tensioning part 201 are arranged on the bottom surface of the collapse frame, concave sliding rails 202 are arranged on two sides of the collapse frame, and a second limiting bump 203 is arranged at the head of each concave sliding rail 202; the energy absorption base 100 is of a concave structure, a first limiting cavity 103 and a second tensioning part 102 are arranged on the bottom surface of the energy absorption base, sliding grooves 101 matched with concave sliding rails 202 are arranged on two sides of the energy absorption base, and the matching of the concave sliding rails 202 and the sliding grooves 101 can enable the crumple frame 200 and the energy absorption base 100 to slide relatively; the head of the chute 101 is further provided with a second limit cavity 104 matched with the second limit bump 203, and the limit cavity is used for limiting the limit position of the relative sliding between the crumple frame 200 and the energy absorption base 100, and the limit position is a second limit position; one end of the spring 300 is detachably connected with the first tensioning part 201, and the other end is detachably connected with the second tensioning part 102; the arrangement of the spring 300 can make the energy absorption frame 200 generate a tensile force on the energy absorption base 100, so that the energy absorption base 100 can rapidly slide relative to the energy absorption frame 200 to reach a limit position; as shown in fig. 2, the lidar 400 is mounted on the energy-absorbing base 100, and the mounting is outward convex due to the characteristic that the lidar 400 needs to measure data, at this time, under the tensioning force of the spring 300, the first limit bump 204 in the crush frame 200 is matched with the first limit cavity 103 in the energy-absorbing base 100 for limiting and jacking, the position of limiting and jacking is the first limit position, and the energy-absorbing base 100 and the crush frame 200 do not generate relative displacement; after collision, as shown in fig. 3, the collision force breaks through the limit fit between the first limit bump 204 and the first limit cavity 103 in the first limit position, the energy-absorbing base 100 is rapidly pulled back under the action of the spring 300 until the second limit bump 203 and the second limit cavity 104 are matched to reach the second limit position, and the lidar 400 on the energy-absorbing base 100 can be better protected under the condition that the collision force is not too large during collision.
In one embodiment, as shown in fig. 3, when the second limit bump 203 is engaged with the second limit cavity 104, that is, the second limit position is reached, the energy-absorbing base 100 is completely retracted inside the collapsing frame 200, and since the energy-absorbing base 100 drives the lidar 400 to be completely retracted inside the collapsing frame 200, even if further collision occurs, the collision force preferentially acts on the collapsing frame 200, so as to effectively prevent the lidar 400 from being collided, therefore, the energy-absorbing base 100 can be completely retracted inside the collapsing frame 200 at the engagement position of the second limit bump 203 and the second limit cavity 104 through the structural design, and the anti-collision capability can be further enhanced.
In some embodiments, energy absorbing base 100 is further provided with threaded holes 105 on a bottom surface thereof, and threaded holes 105 are used to secure lidar 400.
In some embodiments, the crush can 200 is secured to the front cross member of the vehicle.
