Problems solved by technology
The vehicle can be unlocked by vibration and simple external force, which poses a safety risk
[0009] Second, the unlocking and locking operations are complicated, and the mechanism coordination tolerance is small, which requires high precision and action dimensions for automatic replacement equipment, making it difficult to realize automatic operation
Difficulties in unlocking and locking often occur due to changes in vehicle attitude and inaccurate positioning of automatic battery replacement equipment
[0010] Therefore, in the locked state of the battery box locking device in the prior art, the lock tongue will automatically retract due to the bumps of the car body, which will cause the locking failure of the battery box locking device during the operation of the car body.

Embodiment Construction
[0029] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0030] like figure 1 As shown, the battery case locking device according to the embodiment of the present invention includes a locking mechanism 1 , an interlocking mechanism 2 and an anti-unlocking mechanism 3 .
[0031] Wherein, the locking mechanism 1 has a locked state and an unlocked state. The locking mechanism 2 includes a locking body 21 connected with the locking mechanism 1 and an unlocking fitting part 22 . The interlocking mechanism 2 controls the locking mechanism 1 to switch between a locked state and an unlocked state.
[0032] like figure 2 As shown, in this embodiment, preferably, the locking body 21 includes a locking plate 211 . The locking plate 211 has a first axial t...

The invention provides a battery box locking device comprising a locking mechanism, an interlocking mechanism and a compensating mechanism. The locking mechanism has a locking state and an unlocking state. The interlocking mechanism comprises an interlocking body connected with the locking mechanism; the interlocking mechanism controls the locking mechanism to switch between the locking state and the unlocking state; the locking mechanism comprises a bolt, a first link and a second link; the first end of the first link is detachably hinged to the bolt; the first end of the second link is hinged to the second end of the first link; the second end of the second link is hinged to the interlocking body; the compensating mechanism is located between the bolt and the first link and can apply a force to the bolt so that the bolt leaves the first link. The battery box locking device has the advantage that bolt damage caused by rigid contact between the bolt and a lock post of an outer box can be relived.
Description
technical field [0001] The invention relates to the field of vehicles, and more specifically, to a locking device for a battery box. Background technique [0002] Pure electric commercial vehicles are mainly realized by charging the whole vehicle and replacing the battery. Among them, replacing the battery is to regard the battery as a detachable device, and realize it by separating the vehicle body, centralized charging, and quick replacement. In addition, the battery is usually fixed in the body of the commercial vehicle through the battery box locking device. In order to improve the reliability and safety of the commercial vehicle, the battery box locking device that locks the inner box containing the battery The following technical requirements need to be met: [0003] First, high reliability, that is, once the battery is locked, there will be no problems such as battery throwing off and structural deformation; [0004] Second, the positioning accuracy is high, that is...
