Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery technology, and in particular to a detachable battery module. Background Technology
[0002] Patent document CN220710520U discloses a detachable battery module, relating to the field of battery module technology. The module includes a housing with a placement plate fixedly connected to its upper surface. A battery pack is placed on the upper surface of the placement plate. Movable components are provided on both sides of the placement plate, and these two components are symmetrical about the placement plate. The housing also has fixing components for securing the battery pack. By using these fixing components, when installing the battery pack, simply place it between two clamping plates and then turn the handle clockwise to clamp and secure it. Similarly, when removing the battery pack, simply turn the handle counterclockwise to release the fixing and remove it from the placement plate. This allows for single-person installation and removal of the battery pack, significantly saving manpower.
[0003] However, the battery module lacks a limiting unit, which reduces its assembly accuracy. Therefore, it is necessary to improve this structure to overcome the aforementioned shortcomings. Utility Model Content
[0004] The purpose of this invention is to provide a detachable battery module to solve the problems mentioned in the background art.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A detachable battery module includes an upper housing and a lower housing. The upper housing has a snap-fit groove that limits the position of the lower housing. The snap-fit groove has a snap-fit protrusion with a trapezoidal cross-section. The lower housing has a fixing groove that penetrates through the lower housing and corresponds to the position of the snap-fit protrusion in the upper housing. The upper housing has a connecting unit, and the lower housing has a limiting unit that guides the lower housing.
[0007] The present invention is further configured such that the connecting unit includes:
[0008] Connecting buckles are provided on both sides of the upper housing, and the bottom of the connecting buckle is provided with a snap-fit part, which is used to snap the connecting buckle with the assembly component;
[0009] The bump is located in the upper housing and increases the friction of the upper housing.
[0010] The present invention is further configured such that the limiting unit includes:
[0011] Guide bars are provided on the outer surface of the lower housing. There are two pairs of guide bars, and the guide bars are arranged vertically.
[0012] A limiting block is disposed in the lower housing and is located at the top of the guide bar.
[0013] The present invention is further configured such that a battery pack is disposed in the lower housing.
[0014] The present invention is further configured such that a supporting protrusion is provided in the upper housing, which supports and limits the battery pack.
[0015] The present invention is further provided with a fixing seat at the bottom of the lower housing, and a connection port is provided in the fixing seat, which is electrically connected to the battery pack.
[0016] The advantages of this utility model are:
[0017] 1. This utility model is equipped with a connecting buckle and a protrusion, which realizes the snap-fit between the upper shell and the assembly component. When the battery module needs to be replaced, simply press the connecting buckle to disengage the battery module from the assembly component, thereby replacing the battery module, reducing the battery module replacement time and making the battery module replacement more convenient.
[0018] 2. This utility model is provided with guide strips and limiting blocks. The guide strips guide the movement direction of the lower housing, while the limiting blocks abut against the assembly parts to limit the lower housing, thus ensuring the assembly accuracy of the lower housing.
[0019] 3. By setting protrusions, this utility model increases friction when pressing the connecting buckle, avoiding slippage caused by the excessive smoothness of the upper housing surface, and reducing the disassembly time of the battery module. Attached Figure Description
