Description

Technical Field

[0001] The utility model belongs to the technical field of battery replacement frame locking, and specifically relates to an impact-resistant battery replacement locking device for a heavy-duty battery replacement frame. Background Art

[0002] The battery swap vehicle is provided with a battery box for energy storage and a bottom bracket device for fixing the battery box. The bottom bracket device is provided with a locking device for locking the battery box, wherein when the locking device is in the locking position, the battery box and the bottom bracket device are locked to keep the installation positions of both fixed. In the existing battery swap system, a positioning device is usually provided in the bottom bracket to limit the structure corresponding to the battery swap battery frame, so as to achieve the horizontal limit of the battery swap battery frame, and then the battery frame and the bottom bracket are limited in the vertical direction by the battery swap locking device to achieve overall locking.

[0003] For example, in the prior art CN116130870A, the telescopic or rotating lock tongue of the locking mechanism realizes the upper and lower limit of the battery frame and the bottom bracket. Since the battery frame itself is very heavy, according to different battery power configurations, especially for the battery replacement system in the mining scene, its weight can be up to 15 tons. Therefore, the upper limit in the vertical direction is subject to a large impact. When the vehicle is subjected to bumps and other impacts during operation, the locking device directly bears the impact, which can easily cause the actuator to deform or even be damaged, affecting the durability and reliability of the system. Therefore, the utility model provides a durable and impact-resistant battery replacement locking device. Utility Model Content
