Description

Technical Field

[0001] This utility model belongs to the field of battery box technology, specifically relating to a module end plate with a fixing device and a battery box. Background Technology

[0002] Battery packs used in commercial vehicles typically face harsh operating environments, requiring higher reliability to ensure normal operation. Currently, high-profile battery packs have internal module end plates divided into upper and lower layers, connected by long bolts. During battery pack vibration, these long bolts can loosen, causing damage to the battery pack system and related components. Utility Model Content

[0003] The purpose of this utility model is to provide a module end plate and battery box for a fixing device, which can effectively improve the overall strength of the battery box, greatly reduce the loosening of long bolts on the module end plate, and improve the reliability of the battery pack system.

[0004] To achieve the above objectives, the present invention provides a module end plate with a fixing device, including a module end plate body, wherein at least one end of the module end plate body is guided and mounted with a slider along the length direction, and the slider is connected and fixed to the module end plate body and the battery box body through a fixing member.

[0005] As a further embodiment of this utility model: the module end plate body is provided with a sliding groove, the slider is slidably installed in the sliding groove, and the module end plate body is provided with an elongated hole that communicates with the sliding groove and is vertically arranged.

[0006] As a further embodiment of this utility model: the fixing member includes a horizontal screw and a vertical screw, the vertical screw is installed in the elongated hole, and the slider is provided with a vertical nail hole that matches the vertical screw and a horizontal nail hole that matches the horizontal screw.

[0007] As a further embodiment of this utility model: an annular groove is provided on the outer end face of the slider, and a sealing gasket is installed in the annular groove.

[0008] As a further embodiment of this utility model: at least one end of the module end plate body has a connecting block protruding outward along the length direction, and a groove is opened inward from the outer end of the connecting block.

[0009] To achieve the above objectives, this utility model also provides a battery box, including a box body and a box cover that matches the box body, and the aforementioned module end plate with fixing device is installed inside the box body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The vertical screws, when loose, allow the slider to move horizontally and adjust in conjunction with the elongated hole, facilitating smooth insertion of the module end plate into the battery box during assembly. Tightening the vertical screws improves the overall integrity of the slider and the module end plate. The horizontal screws secure the slider to the battery box, thus fixing the module end plate to the box, enhancing the stability of the module end plate, reducing the loosening of the long bolts on the module end plate, improving the overall reliability of the battery box, and extending the battery pack's lifespan.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the module end plate with fixing device includes a module end plate body 1. At least one end of the module end plate body 1 is guided and installed with a slider 4 along the length direction. The slider 4 is connected and fixed to the module end plate body 1 and the battery box housing 9 by a fixing member.

[0018] The slider 4 is connected to the module end plate through a fastener, which can improve the integrity of the slider 4 and the module end plate. The slider 4 is connected to the housing 9 through a fastener, which can fix the module end plate to the housing 9, thereby enhancing the stability of the module end plate.

[0019] In order to guide and install the slider 4 on the module end plate body 1, the module end plate body 1 is further provided with a slide groove 3, the slider 4 is slidably installed in the slide groove 3, and the module end plate body 1 is provided with an elongated hole 11 that communicates with the slide groove 3 and is vertically arranged.

[0020] Furthermore, the fasteners include a horizontal screw 7 and a vertical screw 10. The vertical screw 10 is installed in the elongated hole 11. The slider 4 has a vertical screw hole 5 that matches the vertical screw 10 and a horizontal screw hole 6 that matches the horizontal screw 7. When the vertical screw 10 is not tightened, the slider 4 can be adjusted horizontally, which facilitates the insertion of the module end plate into the box. When the vertical screw 10 is tightened, the slider 4 and the module end plate body 1 can be connected as a whole.

[0021] To enhance the sealing performance between the module end plate and the housing 9, an annular groove is provided on the outer end face of the slider 4, and a sealing gasket 8 is installed inside the annular groove. The compression ratio of the sealing gasket 8 is preferably 10%. After the transverse screw 7 is tightened, the sealing gasket 8 can be compressed to achieve a sealing effect.

[0022] To better accommodate the installation of blade cells with terminals on both sides, space needs to be reserved for the terminals. Furthermore, at least one end of the module end plate body 1 has a connecting block 2 protruding outward along the length direction, and a groove 3 is opened inward from the outer end of the connecting block 2. The module end plate body 1 and the connecting block 2 are integrally formed.

[0023] like Figure 2 and Figure 3 As shown, the battery box includes a box body 9 and a box cover 13 that matches the box body 9. The aforementioned module end plate with fixing device is installed inside the box body 9.

[0024] In specific implementation of this utility model, such as Figure 2 and Figure 3 As shown, when the module end plate is placed into the box, the slider 4 retracts to the module end plate for module end plate assembly. The module end plate is distributed in two layers, upper and lower. After the module end plate is placed into the box, it is connected to the horizontal screw hole 6 on the slider 4 by the horizontal screw 7. Then, a long screwdriver is used to tighten the vertical screw 10 in the long hole 11 of the lower module end plate by passing through the long hole 11 of the upper module end plate. Then, the vertical screw 10 is placed into the long hole 11 of the upper module end plate and tightened. The lower module end plate is fixed first, and then the upper module end plate is fixed. Finally, the upper and lower module end plates are fixed by the long bolt 12.
