The invention discloses a battery fixing bracket which comprises a battery fixing part and an energy-absorbing buffering part, wherein the battery fixing part is fixed on a forebay beam, and the energy-absorbing buffering part is a hollow support; one end of the energy-absorbing buffering part is fixed on the battery fixing part, and the other end of the energy-absorbing buffering part is fixed on a lower beam of an automobile front baffle plate; and the energy-absorbing buffering part is provided with a plurality of circles of buffer bins. The battery fixing bracket is simple in structure, light in weight and convenient to install and disassemble and simultaneously can be used for enhancing the safety performance of an automobile and relieving injuries to passengers caused by invasion of a battery into a passenger cabin after collision.
Description
Technical field
The present invention relates to electric automobile field, in particular, relate to the battery fixing bracket of electric automobile.
Background technology
At present, the battery of electric automobile, in order to meet the user demand of electric motor car course continuation mileage, forms by many little battery unit encapsulation.Battery pack after encapsulation is bulky, and quality is heavier, can reach up to a hundred kilograms at most.In order to guarantee the stability of the serviceability of battery, all stacks of cells are encapsulated in a firm housing, then are fixed to automotive interior.The patent No. is a kind of electric vehicle battery support of describing in CN200910185071.2, battery is fixed on the crossbeam in front deck by battery bracket, just battery is played to fixation, such mounting support structure, when automobile clashes into due to unexpected generation, the front deck space of automobile can diminish rapidly, cause battery to be pushed to the space that driving cabin ties up driving cabin, passenger space is dwindled rapidly, cause passenger to be subject to grievous injury, even cause life danger.
Summary of the invention
Technical problem to be solved by this invention is to realize a kind of support of self-contained battery, this support can be when automobile bumps absorption portion collision energy, avoid battery of electric vehicle due to the intrusion of collision to passenger compartment, guarantee that passenger has larger safe space, reduce the injury that collision produces.
To achieve these goals, the technical solution used in the present invention is: a kind of battery fixing bracket comprises battery fixed part and energy-absorbing buffering portion, the support that described energy-absorbing buffering portion is hollow, its one end is fixed on battery fixed part, the other end is fixed on automotive interior, and energy-absorbing buffering portion is provided with a few dashpots.
Described battery fixed part comprises battery tray, be fixed on the mounting bracket of pallet both sides, be fixed on battery tray bottom surface and stretch out supporting plate and the cover plate of its both sides, described cover plate is positioned on battery, and its two ends are connected and coordinate with pallet clamping battery with supporting plate by bolt.
Described mounting bracket is all secured by bolts on front deck crossbeam and front longitudinal, and one end that automotive interior is fixed in described energy-absorbing buffering portion is secured by bolts on automotive front baffle plate sill.
Described dashpot cross section takes the shape of the letter U, V-arrangement or W shape.
The invention has the advantages that this supporting structure is simple, quality is light, is convenient to installation and removal, has strengthened the security performance of automobile simultaneously, has alleviated battery after collision and has invaded the injury in passenger compartment, passenger being caused.
