Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and in particular relates to a pluggable battery module fixing structure. Background Technology

[0002] Currently, battery cabinets are typically shipped empty to customer sites, with modules and main control boxes shipped separately and assembled into the cabinet upon arrival. To achieve full cabinet transportation and meet transportation testing requirements, the modules need to be fixed to the cabinet both front and back.

[0003] Since the entire container is shipped to the customer's site, the front and rear fixed modules need to be removed to meet the needs of later maintenance. This requires removing the rear door first and then removing the rear fixing, which is quite troublesome. Some door panels have large installation gaps, making them difficult to disassemble and reassemble. If the installer misses this process of removing the rear fixing, it will affect later maintenance. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a pluggable battery module fixing structure, aiming to solve the problems of cumbersome disassembly and assembly and the impact on later maintenance of existing battery module rear fixing structures during transportation. This utility model's pluggable battery module fixing structure, by fixing the plug back plate to the cabinet column and using the plug's limiting function, allows the module to be pushed into the chassis from the slide rail, achieving a good fixing effect without the need for screws, thus facilitating the requirements of full cabinet transportation and the convenience of on-site maintenance for customers.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] A pluggable battery module fixing structure includes a battery module, a module backplate connector, a pin backplate, a pin welding piece, and a pin limiting pin.

[0009] Preferably, the pin limiting pin is provided with a pin limiting groove, which is disposed on the side of the pin limiting pin body. The pin limiting groove is matched with the limiting protrusion on the pin welding piece; it is used to limit the setting direction of the pin limiting pin body.

This enables the pin-limiting pin body to be positioned within the matching and insertion of the pin base hole, avoiding the slippage of the cylindrical pin body used in traditional fixing methods.

[0013] Preferably, the module backplate connector is fixed to the module backplate using countersunk screws.

[0014] Preferably, the pin welding piece and the pin back plate are fixedly connected by a pop rivet.

[0016] Preferably, the pin back plate is provided with heat dissipation holes, which increase the heat dissipation performance of the battery module.

[0017] Preferably, the pin back plate has fixing holes at both ends, which are used to fix the pin back plate to the upright of the battery cabinet.

[0018] This utility model's plug-in battery module fixing structure, by fixing the plug back plate to the cabinet column and using the plug limit pin, allows the battery module to be pushed into the chassis from the slide rail, achieving a good fixing effect without the need for screws. This facilitates the requirements of the entire cabinet transportation and the convenience of customers' on-site maintenance.

[0019] The assembly and usage method of the pluggable battery module fixing structure of this utility model is as follows:

[0020] First, fix the module backplate connector to the inner side of the module backplate with countersunk screws; weld the pin limiting pin to the pin welding piece, assemble the pin welding piece onto the pin backplate with pop rivets, assemble the pin backplate onto the rack column, push the battery module into the rack, and achieve plug-in and pull-out rear fixation of the battery module by cooperating with the pin base post hole on the module backplate and the pin limiting pin on the pin backplate.
