Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1 to 3, the electric vehicle provided by the utility model comprises a front tire 1, a vehicle body threshold 4, a battery pack edge beam 5, a battery pack 6 and a front longitudinal beam 3, wherein the front longitudinal beam 3 is connected to the vehicle body threshold 4. This embodiment includes function block body 2, function block body 2 is installed on automobile body threshold 4, just function block body 2 is located preceding tire 1 with between the automobile body threshold 4. This function block body 2 can puncture preceding tire 1 rapidly and spread the automobile body rear portion with the aluminium alloy frame that the power that preceding tire 1 passed was passed to battery package 6 when the collision to reduce the direct extrusion automobile body threshold 4 of preceding tire 1 when the collision, lead to the threshold conquassation, the tire extrudees battery package 6 and makes battery package 6 have the potential safety hazard.

Aiming at small offset collision, the function block body 2 is additionally arranged in the front of the car body threshold 4, the function block body 2 extends to protrude out of the front end of the car body threshold 4, so that the front tire 1 moves backwards in collision, the contact between the front tire 1 and the function block body 2 is earlier than that between the front tire 1 and the car body threshold 4, on one hand, the function of puncturing the front tire 1 in advance can be achieved, on the other hand, the extrusion force of the front tire 1 to a car body is changed into forward extrusion to the function block body 2 and is transmitted to the battery pack edge beam 5, after the function block body 2 is crushed, then the extrusion to the car body threshold 4 by the front tire 1 is achieved, the extrusion to the car body threshold 4 by the front tire 1 is reduced, the deformation of the front part of the car body threshold 4 is reduced, and the safety space of the front tire 1 and the battery pack 6 is further guaranteed.
