In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

As shown in fig. 1 and 2, a lidar mounting device provided in an embodiment of the present disclosure includes a first mount 1, a second mount 2, and a failure protector 3; the first mounting part 1 is provided with a first connecting part 111 connected with the vehicle body in a mounting way and a mounting part 121 for mounting the laser radar; the second mounting piece 2 is provided with a second connecting part 21 which is connected with the vehicle body in an installing way, and the second mounting piece 2 is correspondingly arranged below the first mounting piece 1; one end of the failure protection piece 3 is connected with the first mounting piece 1, and the other end is connected with the second mounting piece 2; the mounting portion 121 is fixedly connected to the second mount 2 via the failure protector 3, or the mounting portion 121 breaks the failure protector 3 and disconnects it from the second mount 2.

This laser radar installation device is when using, at first can correspond preceding crashproof roof beam and the front bumper of erection joint in the automobile body through first connecting portion 111 in first installed part 1, then correspond erection joint in the automobile body and be located first installed part 1 below through second connecting portion 21 in second installed part 2, again will become invalid the both ends of protection piece 3 respectively with first

installed part

1, 2 erection joint of second installed part, will fix the laser radar installation through installation department 121 in first installed part 1 at last, so can realize the final installation with laser radar.

Compare with prior art traditional car laser radar mounting bracket, fixed connection can be stabilized in first installed part 1 and second installed part 2 to the inefficacy protection piece 3 among the laser radar installation device that this disclosed embodiment provided at normal operating mode, thereby laser radar's installation use precision has been ensured, when laser radar and pedestrian's shank bumps and receives the impact acting force, laser radar and installation department 121 can 2 displacements of second installed part relatively, and will lose efficacy protection piece 3 and destroy the inefficacy, make

inefficacy protection piece

3 and 2 disconnect connections of second installed part, displacement and the destruction of inefficacy protection piece 3 through installation department 121, fully absorb the impact energy of collision in-process, thereby reduce the wound to pedestrian's shank by a wide margin, fully improve the safety protection performance to the pedestrian.

In addition, it is worth mentioning that in order to enable the failure protection member 3 to be stably connected between the first mount 1 and the second mount 2 under normal conditions and to be damaged and failed in time under collision conditions, the material of the failure protection member 3 may be made weaker than the material of the first mount 1 and the second mount 2, for example, the failure protection member 3 may be, but not limited to, an injection-molded pin or an injection-molded bolt made of plastic, and the failure protection member 3 may break when subjected to a certain amount of transverse shear stress.

In some specific embodiments, the first mounting member 1 includes a first plate 11 and a second plate 12; the first plate body 11 is mounted on the vehicle body in the vertical direction; the second plate body 12 is vertically connected with the first plate body 11; the mounting part 121 is opened on a side of the second plate 12 opposite to the second mounting part 2; the second plate 12 can drive the mounting portion 121 to move toward the first plate 11 and cut off the failure protection member 3.

Specifically, as will be described in further detail with reference to fig. 1, the first mounting part 1 is specifically configured as a first board body 11 and a second board body 12 which are perpendicular to each other, and the first board body 11 is mounted on the vehicle body in the vertical direction, and a mounting part 121 for mounting the laser radar is disposed on one side of the second board body 12, which faces away from the second mounting part 2. The laser radar can be installed in the first installation part 1 in a horizontal posture, and the moving mode of the second plate body 12 towards the first plate body 11 can be, but is not limited to, the mode that the second plate body 12 deforms in a shape collapsing manner, and a retractable elastic connecting piece is arranged between the second plate body 12 and the first plate body 11. The energy absorption and cushioning effect of the first mounting part 1 in the laser radar mounting device is fully improved by moving the first absorption part of the impact energy towards the first plate body 11 through the second plate body 12 and transversely cutting off the second absorption part of the ineffective protection part 3 through the second plate body 12.

The concrete structure that sets up of above-mentioned first installed part 1 can regard as the connecting portion with automobile body fixed mounting through first plate body 11, can use as the cantilever that supports installation lidar through second plate body 12, can carry out twice absorption through second plate body 12 and inefficacy protection piece 3 with the impact energy that produces in the collision process, has simple structure, the effectual advantage of energy-absorbing bradyseism.
