Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes, and in particular to a battery box locking structure. Background Art

[0002] At present, most of the existing locking mechanisms of battery box covers adopt highly elastic components. By applying a certain deformation force, the locking mechanism is connected between the battery box and the cover, and then locking is achieved by the rebound force of the elastic components and the friction force of the contact surface between the eccentric wheel, the battery box and the cover. Since the elastic components are used, they need to be compressed when they are locked, and the elastic force of the elastic components themselves makes locking more laborious.

[0003] To solve this problem, application number CN201911177831.5 proposes a battery box with a pressure plate locking mechanism, which includes a battery box and a battery box cover, the battery box cover is arranged on the battery box, the battery box is provided with a transmission rod, the transmission rod is provided with a pressure plate, the pressure plate and the transmission rod are threadedly connected, and the battery box is also provided with a horizontal fixing groove; the battery box cover is provided with a vertical through hole and a horizontal locking hole, the horizontal locking hole is provided with a locking bolt, the transmission rod is arranged in the vertical through hole, and the locking bolt passes through the horizontal locking hole and is arranged in the horizontal fixing groove. The advantage of the present invention is that its structure is simple, which avoids the phenomenon that the battery is likely to become loose due to vibration caused by continuous large external force, thereby preventing the locking from failing. It can also ensure that there is a heat dissipation spacing or gap at the bottom of the battery, and then exchange with the air outside the box through the heat dissipation hole, which can reduce the high heat in the box when the battery is in use and achieve the purpose of cooling.

[0004] The locking mechanism of the battery box in the existing patent requires multiple transmission rods or bolts to be operated sequentially when locking the battery box, and cannot be performed synchronously. The operation is relatively cumbersome. At the same time, the length of the pressure plate is limited. When the battery size is small, it will be impossible to fix the inside of the battery box.

After the fixing plug-in plate and the L-shaped plug-in are fitted together, the fixing cover is fixed to the threaded sleeve by a bolt to fix the fixing mechanism, and finally the battery box is locked. When the battery box needs to be opened, the bolt is manually twisted to separate the fixing cover and the threaded sleeve from each other, and the fixing mechanism is directly taken out to realize opening of the battery box. The battery box can be quickly locked and opened by inserting and removing the fixing mechanism on the battery box shell. The manual operation is simple and multiple components act simultaneously, which avoids the excessive time cost of operating multiple components separately. BRIEF DESCRIPTION OF THE DRAWINGS
