Jaw-type locking mechanism of electric vehicle battery box

Abstract

The invention discloses a jaw-type locking mechanism of an electric vehicle battery box. The jaw-type locking mechanism of the electric vehicle battery box comprises a jaw-type outer plate fixedly arranged on the outer side wall of the battery box, and a locking mechanism body fixedly arranged on a sliding track of the battery box. The locking mechanism body comprises a frame shell body with an opening in one end, and the frame shell body is internally movably provided with a jaw-type inner plate matched and meshed with the jaw-type outer plate; one side of the jaw-type inner plate is connected with a bottom side plate of the shell body through a first reset spring, the other side of the jaw-type inner plate is provided with a cam mechanism, the two ends of the cam mechanism are arranged on two end plates of the shell body in a penetrating manner, and automatic rotating is realized; the jaw-type inner plate is driven to move through rotating the cam mechanism to be meshed with or separated from the jaw-type outer plate, and thus the battery box is controlled to be locked and released. The jaw-type locking mechanism is compact in structure, convenient to operate and capable of meeting requirements of multi-functionality of bearing the axial and radial load.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a jaw-type locking mechanism for a battery box of an electric vehicle. Background technique [0002] With the development of society, electric vehicles with zero emissions have become the development direction of future automobiles, which also forces the promotion and application of battery technology to become the main factor restricting the rapid development of electric vehicles. A plurality of batteries are connected in series and parallel to form a battery box, which is fixed in the cargo compartment of the electric vehicle through a locking device, and the connection and separation of the battery box and the locking and unlocking function of the battery box in the charging rack are realized through power or a switch. The traditional battery box locking device requires an independent control system, the structure is more complex, and there are many steps for action coordination, which...

Problems solved by technology

[0004] In order to achieve the purpose of automatic replacement, the application number is 201420086771.2 and an automatic locking device with a motor as the power source is announced. This patent can automatically realize the disassembly and assembly of the battery box, but in the case of errors, several locking The device cannot be locked at the same time, and the rack and pinion cannot be used for a long time under the vibration environment during use

In addition, this device requires a large space for the battery compartment, which puts forward higher requirements for the design of the battery box and guide rails
