Detailed Description

The technical solutions in the implementation of the present invention will be clear from the following description and accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the embodiment of the utility model provides a pair of electric motor car anticollision frame, including protection frame 1, the backup pad 2 that is used for joint support protection frame 1 and fix the rod cover 5 in backup pad 2, it has buffer beam 3 to peg graft in the rod cover 5, is equipped with the buffer 4 that is used for absorbing the striking kinetic energy on the buffer beam 3, be equipped with on the buffer 4 and be used for the connecting plate 45 with automobile body fixed connection, buffer beam 3 and rod cover 5 pass through bolt fixed connection. Adopt bolted connection convenient to detach, through setting up buffer beam 3 and buffer 4 for when protection frame 1 meets the striking, partly kinetic energy of striking is absorbed the storage by buffer 4, thereby alleviates the striking to the damage of pedestrian and vehicle.

Preferably, the buffering device 4 includes a cylinder 41 and end covers 43 arranged at two ends of the cylinder 41, the buffering rod 3 passes through the cylinder 41 and the end covers 43, the baffle 31 is arranged on the side wall of the buffering rod 3 between the two end covers 43, the spring 44 is sleeved on the portion, located between the end cover 43 and the baffle 31, far away from the rod sleeve 5, of the buffering rod 3, the hinged limiting teeth 32 are arranged on the side wall of the side, far away from the spring 44, of the baffle 31 of the buffering rod 3, the limiting tooth grooves 42 matched with the limiting teeth 32 are arranged on the inner wall of the cylinder 41, and the limiting teeth 32 and the limiting tooth grooves 42 are used for limiting the buffering rod 3 to move only in the direction of compressing the spring 44 in the cylinder 41. As shown in fig. 4, by arranging the limiting teeth 32, the limiting tooth grooves 42, the springs 44 and other components, the kinetic energy of the impact is transmitted to the springs 44 through the buffer rods 3, the kinetic energy is converted into elastic potential energy, and the springs 44 cannot rebound to release the elastic potential energy under the matching of the limiting teeth 32 and the limiting tooth grooves 42, so that the kinetic energy of the impact is stored, and the damage to the vehicles and the pedestrians is reduced.
