It should be noted that, the "collision sensor" in the embodiment of the present utility model refers to a sensor disposed on a vehicle and used for sensing a collision of the vehicle, for example, an acceleration sensor disposed on a front bumper of the vehicle, where the front bumper of the vehicle drives the acceleration sensor to shift during the collision, and the vehicle determines a collision accident and a collision strength of the vehicle according to an acceleration shift signal of the acceleration sensor, and the "vehicle frame" refers to a vehicle body beam, a longitudinal beam, or a beam of the bumper (including a beam of the front bumper and a beam of the rear bumper); "vehicle housing" refers to sheet metal vehicle housings of vehicles, such as front and rear bumpers.

The vehicle generally is provided with a collision sensor for sensing the collision of the vehicle, the traditional arrangement mode of the collision sensor is that the collision sensor is arranged on a front bumper or a rear bumper of the vehicle, when the front bumper or the rear bumper of the vehicle is slightly impacted, the bumper triggers the collision sensor to generate a sensing signal, the sensing signal triggers the vehicle to start the active safety system, however, in the actual use process, the phenomenon of false triggering of the active safety system can occur when the vehicle is slightly impacted, and the false triggering of the active safety system can possibly cause a series of reaction phenomena such as sudden braking, airbag ejection and the like of the vehicle.

In order to reduce the phenomenon that the vehicle is in a slight collision and the active safety system is triggered by mistake, a buffer part or a buffer gap can be arranged between the collision sensor and the vehicle shell of the vehicle, however, if the buffer part or the buffer gap is unreasonable in design, the collision sensor cannot deform and shift correspondingly along with the vehicle shell, or the collision sensor cannot reset after collision, so that the normal function and the follow-up normal use of the collision sensor are affected.

Further, the plurality of empty slots 222 are distributed at intervals along the width direction of the bending portion, so that the plurality of empty slots 222 can disperse the collision force born by the vehicle, and the phenomenon that local stress is overlarge due to stress concentration at the bending portion is reduced.

As shown in fig. 1 to 4, in some embodiments, the connection plate is provided as a transverse plate or an inclined plate, in which case the cantilever 23 is higher than the mounting base 21, the transverse plate connects the bottom of the cantilever 23 with the top of the mounting base 21, and in which case the cantilever 23 is at the same height as the mounting base 21, the cantilever 23, the inclined plate, and the mounting base 21 are sequentially connected to form an N-type structure.

Similarly, the cantilever 23, the connecting plate and the mounting base 21 are sequentially connected to form an N-type structure, the connecting plate is obliquely distributed, so that the connecting plate has good structural stability and deformability, specifically, the inclined plate has a compression space and an extension space (refer to a folding door and a spring), and the inclined plate can stretch and retract along the direction of a collision force after bearing the collision force, so that the collision force and the collision direction of the collision force are truly represented, and the detection accuracy of the collision sensor 30 is improved.

In addition, the connection plates are provided as the lateral plates or the diagonal plates, and also in relation to the height difference between the cross member of the vehicle frame 10 and the vehicle housing 40, when the vehicle housing 40 is higher than the cross member of the vehicle frame 10 by a large height, the connection plates may be provided as the lateral plates, and at this time, the cantilever 23, the connection plates, and the mounting base 21 are distributed in the height direction, so as to compensate for the large height difference between the vehicle housing 40 and the cross member of the vehicle frame 10; when the vehicle housing 40 is higher than the cross member of the frame 10 by a small height, the connection plate may be provided as a diagonal plate, and the cantilever 23 and the mounting base 21 are substantially aligned in the height direction, thereby accommodating the height distribution between the vehicle housing 40 and the cross member of the frame 10.
