Battery compartment with buffer device

Abstract

The invention relates to the technical field of new energy automobile equipment, and discloses a battery compartment with a buffer device. The battery compartment comprises a battery compartment and a battery pack which are arranged on a vehicle chassis, wherein the lower edge of the battery compartment is fixedly connected with a detachable frame through a shear pin. According to the invention, when the battery compartment with the buffer device encounters large impact, a rotating rod extends out, the forward motion of a battery pack is converted into circular motion parallel to the ground, kinetic energy is consumed under the action of damping and friction, impact force received by the battery pack is reduced, and a good protection effect on the battery pack is achieved, so that the probability that a vehicle is on fire after collision is reduced, and life and property are better protected; and the battery compartment and the battery pack are in large interference fit so as to facilitate positioning and mounting of the battery pack while a clamping bag always provides high pressure, so that it is guaranteed that clamping plates clamp the battery pack, and the battery pack is firmly assembled and shakes are reduced.

Description

technical field [0001] The invention relates to the technical field of new energy automobile equipment, in particular to a battery compartment with a buffer device. Background technique [0002] With the improvement of the quality of life, people's requirements for the environment are getting higher and higher. In order to reduce the particulate matter in the urban air, electric vehicles without tail gas emissions have been developed relatively rapidly. [0003] However, with the increase in the number of electric vehicles, the phenomenon of spontaneous combustion of vehicles frequently occurs, which largely restricts the development and popularization of electric vehicles. When stopping or crashing in an accident, a large force will be exerted on the battery, which will cause the battery to be squeezed, deformed and leaked, which will cause spontaneous combustion. Especially in a large traffic accident, the deformation and extrusion of the vehicle will cause the battery to ...

[0003] However, with the increase in the number of electric vehicles, the phenomenon of spontaneous combustion of vehicles frequently occurs, which largely restricts the development and popularization of electric vehicles. When stopping or crashing in an accident, a large force will be exerted on the battery, which will cause the battery to be squeezed, deformed and leaked, which will cause spontaneous combustion. Especially in a large traffic accident, the deformation and extrusion of the vehicle will cause the battery to spontaneously ignite phenomenon is very common

[0004] Secondly, for new energy vehicles that change batteries, the battery is replaced by a robotic arm, which requires a more precise positioning device. In order to ensure that the battery pack enters and exits the battery compartment smoothly, the fit may be interference, and the battery pack is fastened. The device may also be overwhelmed, which may loosen and cause frequent vibration and damage to the battery pack
