Vibration reduction protection device for new energy automobile battery

Abstract

The invention discloses a vibration reduction protection device for a new energy automobile battery. The vibration reduction protection device comprises a bin body, vibration reduction positioning mechanisms, a cooling protection system and a heat dissipation system, wherein each of the vibration reduction positioning mechanisms comprises a linkage mechanism, a clamping plate, a limiting sleeve, four groups of U-shaped frames, a screw rod, an inner threaded pipe, a second spring and a sleeve pipe, the outer side of the bin body is fixedly connected with four groups of U-shaped frames, the middle positions of the four groups of U-shaped frames are sleeved with lead screws, and inner threaded pipes matched with threads are arranged on the outer sides of the four groups of lead screws. Through a structural system of the bin body and the four groups of vibration reduction positioning mechanisms, a battery pack needing to be protected can be arranged at the center in the bin body, and side edges of the battery packs with different sizes can be attached and positioned through fine adjustment of the structures of the vibration reduction positioning mechanisms, so side surfaces of the batteries are subjected to double vibration reduction effects of the second springs and the first springs; and therefore, the battery is prevented from shaking during running of an automobile.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a vibration damping protection device for batteries of new energy vehicles. Background technique [0002] The new energy vehicle battery is the core component of the vehicle and plays the role of providing energy for the vehicle. "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Lithium battery is also The power batteries of hybrid electric vehicles and electric vehicles, due to some technical properties of nickel-metal hydride batteries, such as energy density, charge and discharge speed, etc., are close to the theoretical limit. [0003] At present, the battery of the car is generally placed in the box for protection, but due to the composition of the protective structure, it may form a sealed package on the outside of the battery pack, which makes ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a vibration reduction protection device for a battery of a new energy vehicle, so as to solve the problem that under the influence of the protective structure of the battery proposed in the above background technology, the heat energy of the battery heat dissipation is often difficult to eliminate, thereby increasing the possibility of spontaneous combustion and explosion of the battery. It is possible that when the car is driving, it may be affected by the terrain to generate relatively strong vibrations, which will cause the battery pack in the car to shake. According to the influence of the vibration frequency, the surface of the battery pack may be damaged and cannot be used, or a relatively strong vibration may occur. The problem of the explosion of the battery caused by the collision
