Unlocking mechanism of battery box of electric vehicle

Abstract

The invention discloses an unlocking mechanism of a battery box of an electric vehicle. The unlocking mechanism of the battery box of the electric vehicle comprises a buffering support, an unlocking pull rod, limiting blocks, boosting rods, sensors and a prepressing rod. The unlocking pull rod is fixed to the buffering support. The unlocking pull rod corresponds to the center of the battery box to be unlocked. The prepressing rod is arranged above the unblocking pull rod. The sensors are arranged at the two ends of the unblocking pull rod. The boosting rods are fixed to the two ends of the buffering support. Each limiting block is fixed to one side of the corresponding boosting rod. According to the unlocking mechanism of the battery box of the electric vehicle, the middle petal-shaped unlocking rod improves the reliability of the unlocking mechanism when the unlocking mechanism pushes and pulls the battery box, the battery box will not slide off under the conditions of vibration and inclination, and the risk of falling of the battery box is avoided; the two boosting rods arranged on the sides facilitate the balance of the battery box when the battery box is pushed and pulled and increase the pushing force exerted by the unlocking mechanism on the battery box, and therefore the battery box can enter a bracket more smoothly; due to the design of auxiliary rings, the unlocking mechanism is elaborate in structural design and convenient to machine and maintain, and reduces machining cost.

Description

technical field [0001] The invention relates to an unlocking mechanism for a battery box of an electric vehicle. Background technique [0002] During the "Twelfth Five-Year Plan" period, the development of new energy vehicles including electric vehicles has become the main theme of China's auto industry. But how to charge electric vehicles is a difficult problem that must be faced to make it "run further". It is understood that there are two main ways to charge electric vehicles under current technical conditions: plug-in charging and replacement charging. The industry generally believes that a better way to solve the power supply problem of large electric vehicles is to build a power station, that is, to use the method of replacing the battery of the car to replace the long charging process. [0003] Since the battery box is fixed by a mechanical locking operating mechanism, the unlocking mechanism is designed to facilitate the automatic operation to quickly unlock and re...

Problems solved by technology

[0004] The existing battery box unlocking mechanism has a T-shaped hook type and a spherical push-pull type. However, the T-shaped hook type often has the problem that the type hook protrudes outside the box body, which is not convenient for the installation and transportation of the box body; the spherical push-pull type When unlocking, due to the spherical slider in front, it is easy to cause the battery box to slip and cause accidents.
