Quick assembling and disassembling locking mechanism of battery box

Abstract

The invention discloses a quick assembling and disassembling locking mechanism of a battery box. The quick assembling and disassembling locking mechanism comprises a fixed locking seat, a locking piece arranged on the locking seat in a self-rotating manner and a torsion spring with the two ends extending outwards to form a V shape. a cross-shaped hook through hole is formed in the upper portion ofthe locking piece, the middle of the locking piece can contain a cross-shaped hook passing through the cross-shaped hook through hole, and the lower portion of the locking piece can be matched with atool for operating the locking piece to rotate; when the locking piece rotates, two extreme positions, namely a locking position and an opening position, exist on the locking seat; the locking pieceis hung on the cross-shaped hook when located at the locking position and disengaged from the cross-shaped hook through the cross-shaped hook through hole when located at the opening position, the twoends of the torsional spring are connected with the locking piece and the locking seat respectively, and the two ends of the torsional spring are shrunk and then expanded when the locking piece is switched between the locking position and the opening position; and the two ends of the torsional spring always have the expansion tendency under the condition without external force action, and the locking piece can be kept at the locking position and the opening position. The quick assembling and disassembling locking mechanism can be quickly assembled and disassembled and is not easy to slip.

Description

technical field [0001] The invention belongs to the field, and in particular relates to a quick assembling and disassembling locking mechanism of a battery box. Background technique [0002] The promotion of pure rechargeable electric vehicles is affected by reasons such as short driving range and long charging time. If the battery is quickly disassembled after the battery is exhausted, and the pre-charged battery system is quickly installed at the same time to ensure the continuous operation of the vehicle, it is a new direction for the development of electric vehicles. [0003] The quick replacement of the power battery can be achieved at the power exchange station with the help of power exchange equipment, so what kind of fixing method can be used to install the power battery pack on the body? The usual bolt connection obviously cannot meet the needs of quick replacement of the power battery. Therefore, it is an urgent technical problem to design a fixing method that is...
