Embodiment Construction

[0068] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0069] Aiming at the problem in the prior art that the primary lock body between the power battery pack and the power battery installation device is accidentally unlocked due to external force, the invention provides a locking mechanism and a method for determining the secondary locking state of the power battery installation device.

[0070] Such as figure 1 As shown, the embodiment of the present invention provides a locking mechanism, comprising:

[0071] The first kinematic assembly 1 and the second kinematic assembly 2;

[0072] Wherein, when the second moving assembly 2 is in the first locking position, the second moving assembly 2 abuts against the first moving assembly 1;

[0073] When the second moving assembly 2 pivots to the first unloc...

Abstract

The invention provides a locking mechanism and a method for determining a secondary locking state of a power battery mounting device, and relates to the technical field of electric vehicles. The locking mechanism comprises a first movement assembly and a second movement assembly. When the second moving assembly is located at the first locking position, the second moving assembly abuts against thefirst moving assembly. And when the second moving assembly pivots to the first unlocking position, the second moving assembly is separated from the first moving assembly. According to the locking mechanism, secondary locking of the power battery pack and the power battery mounting device is achieved, and the situation that a primary lock body between the power battery pack and the power battery mounting device is driven by external force to be unlocked by mistake is prevented.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a locking mechanism and a method for determining a secondary locking state of a power battery installation device. Background technique [0002] When the power battery of the electric vehicle is exhausted, it needs to be charged immediately to ensure the normal driving of the electric vehicle. Although the current charging stations are constantly improving the facilities to make charging more convenient, but in the urgent situation of users, In order to avoid excessive charging time, you can choose to directly replace a fully charged power battery pack at the replacement station when the power of the power battery is insufficient. Although the existing power battery pack and the power battery installation device of the vehicle body are connected through a plurality of primary lock bodies installed on the power battery installation device to realize the locked state, whi...
