Description

A novel module side panel structure Technical Field

[0001] This utility model mainly relates to the field of battery pack accessory structure, specifically to a novel module side plate structure. Background Technology

[0002] Electric vehicles offer advantages such as low noise, high driving stability, and zero emissions, which are of positive significance for maintaining national energy security, reducing exhaust emissions, promoting the development of the automotive industry, and ultimately ensuring sustainable social development. As electric vehicles become increasingly widespread, the demand for battery system energy density is rising, and improving cell energy density has reached a bottleneck. Therefore, reducing the weight of power battery packs, especially module structures, is becoming increasingly urgent.

[0003] The existing module end plates are basically made by extruding aluminum alloy and then precision machining using a CNC machining center. This process is costly, especially the CNC process. Summary of the Invention

[0004] 1. The technical problem to be solved by the utility model:

[0005] This utility model provides a novel module side plate structure to solve the problem that the existing module end plates are basically made of aluminum alloy extrusion and then precision-machined by a machining center CNC, which results in high processing costs.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a novel module side plate structure, comprising a battery, a fixing connecting piece mounted on the upper surface of the battery, an outer ring strip sleeved onto the surface of the battery, and lightweight side plates provided on both sides of the outer end of the battery.

[0008] The lightweight side panel includes a plastic body with a hollowed-out groove on the outer surface of the plastic body. A reinforcing block is fixedly connected to the surface of the hollowed-out groove. Two hexagonal screw grooves are provided on both sides of the upper end of the plastic body, and an aluminum alloy slot is provided between the two hexagonal screw grooves. An inlaid aluminum alloy is fitted and connected to the surface of the aluminum alloy slot.

[0009] Furthermore, the capacity battery is provided in several parts, and two lightweight side plates are provided on the outside of the capacity battery. The capacity battery and the lightweight side plates are fixed by an outer ring strip and a fixing connecting piece. The embedded aluminum alloy is placed in the injection mold and integrally formed by injection molding. After injection molding, the plastic part will wrap the embedded aluminum alloy.

[0010] Furthermore, the batteries are interconnected via a fixing connecting piece at their upper end, and the surface of the fixing connecting piece is provided with screw holes and screws.

[0011] Furthermore, the reinforcing block is configured as an "L" shape, and the reinforcing blocks are symmetrically installed on both sides of the hollow groove surface.

[0012] Furthermore, the inlaid aluminum alloy is formed by an aluminum extrusion process and is fitted and connected to the aluminum alloy slot. The aluminum alloy slot and the inlaid aluminum alloy are located at the center of the plastic body.

[0013] 3. Beneficial effects:

[0014] This invention is reasonably designed. It uses an aluminum alloy process to first process an inlaid aluminum alloy, and then uses an injection molding process to inject the inlaid aluminum alloy into the plastic body. This solution can effectively reduce the weight of the module end plate and reduce procurement costs. Attached Figure Description
