Description

New energy automobile protector that charges Technical Field The utility model belongs to the technical field of charging equipment, and particularly relates to a new energy automobile charging protection device. Background With the rapid popularization of new energy automobiles, the safety and durability problems of the charging pile serving as a core supporting facility are increasingly prominent. In an actual use scene, accidents of vehicles striking the charging pile due to the reasons of reverse operation errors, blind areas of driver vision, wet and slippery ground and the like frequently occur, the charging pile shell is deformed when the vehicle is light, internal elements are damaged, and potential safety hazards such as electric leakage and fire disaster are caused when the vehicle is heavy. Although the existing charging pile protection technology is improved to a certain extent, the following key defects still exist: The buffer structure is single, the energy absorption efficiency is low, the traditional protection device adopts a single-layer rubber pad or a simple spring as a buffer medium, the material compression rate is limited (usually lower than 40%), and the design of multi-stage energy consumption is lacked. Impact energy is concentrated in a single structure, instant overload failure of a buffer layer is easy to cause, residual kinetic energy is directly transmitted to a charging pile main body, structural damage is caused, mechanical decomposition capacity is insufficient, impact redundancy is low, an existing protective frame mostly adopts a rigid structure (such as a steel bracket) in vertical or horizontal layout, and the vector decomposition path of force is not optimized although part of impact can be born. For example, the material strength is insufficient, the yield strength of common aluminum alloy (such as 6061 type) is only about 280MPa, and plastic deformation and even fracture are easy to occur under high-speed impact. The design of no angle guiding is that the impact force is transmitted to the charging pile foundation base along a straight line, and the impact energy cannot be counteracted by component force due to lack of an inclined guide rail or a mechanical decomposition mechanism.
