Twin-lock quick-release locking mechanism

Abstract

The invention provides a double-lock fast dismounting latch mechanism which comprises a double latch mechanism, a fast unlocking mechanism and fittings. One end of a suspension link of the double latch mechanism is arranged at a suspension link locating seat fixed on the side surface of a front door of an inner box body and can rotate by surrounding the suspension link locating seat; the other end can be hung on the head part of a handle to carry out locking; the handle is locked by a bolt to form a first lock; simultaneously, one bolt fixedly arranged at the lower part of the suspension link locating seat is inserted into a jack at the lower part of a handle seat at the front door to form a second lock; the fast unlocking mechanism is also fixedly arranged at the front door; a double bolt is driven by a cam mechanism to control the double latch mechanism and realize the locking or unlocking of the double locks. The mechanism of the invention has the advantages of reliable locking, being convenient and fast to unlock and realizing fast mounting and dismounting of the battery; simultaneously, a centrifugal force and vibration generated when an automobile turns are overcome and the requirements of safe locking of the battery as well as fast mounting and dismounting are ensured.

Description

technical field [0001] The invention relates to a double-lock quick-release locking mechanism, in particular to a double-lock quick-release locking mechanism applied to a power battery box of an electric vehicle. Background technique [0002] The battery monomers of current electric vehicles (such as buses) are connected in series through wires, and the monomers are only connected by wires and bare in metal boxes. The power connection between each battery box is connected with a manual plug and placed at the door on both sides where people can easily access; in this way, the battery connection is too long, the circuit voltage drop is large, the power output is small, and the power loss is large. In addition, the single battery is packaged bare in a metal box, which cannot be fireproof, waterproof, dustproof, or shockproof. It is easy to self-discharge, cause looseness and contact resistance, and affect the consistency and power output of the battery. Moreover, the whole box...

Problems solved by technology

The power connection between each battery box is connected with a manual plug and placed at the door on both sides where people can easily access; in this way, the battery connection is too long, the circuit voltage drop is large, the power output is small, and the power loss is large

In addition, the single battery is packed in a metal box, which cannot be fireproof, waterproof, dustproof, or shockproof, and is prone to self-discharge, looseness and contact resistance, which affects the consistency and power output of the battery.

Moreover, the whole box is fixed with bolts, which cannot realize the overall quick assembly and quick disassembly, and cannot use the quick battery replacement method to expand the continuous mileage, especially lithium batteries are flammable when they are misused. Therefore, their use must have the same Safety conditions for rapid separation
