Description

Technical Field

[0001] This utility model relates to the field of marine battery boxes, specifically to a battery module mounting structure. Background Technology

[0002] Lithium iron phosphate batteries have good thermal stability and are not prone to combustion or explosion under conditions of high temperature or abuse such as overcharging and over-discharging, which reduces safety hazards during navigation when used in ships. The brackets that fix the battery modules inside the battery box are also extremely important, and their rational design directly affects the ease of battery module assembly.

[0003] For example, patent CN216872171U discloses a battery module and battery box. The battery module includes a cell array, an end plate, a fixing band 305, a fixing tube, and a structural heat-conducting component. The end plate directly integrates the functions of a metal end plate and a plastic bracket, which can not only limit the expansion of the cells, but also constrain the fixing band 305, solving the problem of the fixing band 305 sliding up and down, and greatly improving the integration. The expansion force constraint of the battery module adopts the constraint form of upper steel, lower plastic and bottom fixing tube, which can strengthen the overall strength of the battery module. The structural heat-conducting component can greatly increase the heating efficiency of the battery module. Furthermore, the lightweight end plate, fixing band 305, fixing tube and structural heat-conducting component can also reduce the weight of the battery module.

[0004] The aforementioned patented battery module and battery box can reduce the weight and structural complexity of the battery module, improve assembly efficiency, achieve higher integration and lower cost, and enhance structural strength and improve thermal management efficiency to optimize the battery module. However, the disadvantage of the aforementioned patent is that the battery module in the aforementioned patent mainly relies on long screws to fix the end plate to the fixing tube in the horizontal direction. After long-term use, the long screws are prone to bending, resulting in a decrease in the fixing effect.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A battery module mounting structure includes a battery box and a battery module. The battery box includes a base, which includes a base plate, a crossbeam, and a horizontal beam. The crossbeam and the horizontal beam are fixedly installed on the top of the base plate. The horizontal beam is arranged along the length of the base plate, and a crossbeam is provided at the end of the horizontal beam. Adjacent crossbeams and adjacent horizontal beams form a placement groove for placing the battery module. The lower end of the battery module is located in the placement groove. The battery module includes several spaced cells, and spacer plates are provided between adjacent cells. End plates are also provided at both ends of the battery module, and the end plates are fixedly installed on the top of the crossbeam by fixing screws.

[0009] Furthermore, a nut mounting groove is provided at the top of the crossbeam, and a fixing nut is fixedly installed in the nut mounting groove; countersunk holes are provided at both the front and rear ends of the end plate, and fixing screws pass through the countersunk holes and are threadedly connected to the fixing nut.

[0010] Furthermore, a fixing strap is also fixedly installed on the end plate and the periphery of the battery module.

[0011] Furthermore, a fixing strap slot is provided on the side of the end plate, and the fixing strap is accommodated in the fixing strap slot for fixing the end plate and the battery cell.

[0012] Furthermore, the fixing strap is made of stainless steel, and an insulating rubber sleeve is fixed to the surface of the fixing strap that contacts the battery cell.

[0013] Furthermore, the end plate is made of engineering plastic.

[0014] Furthermore, several weight-reducing grooves are vertically formed on the end plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The crossbeams and horizontal beams form a placement groove, which makes the battery module installed firmly and enhances the structural stability.

[0017] By setting spacer plates and fixing straps, the battery cells are effectively constrained to prevent them from expanding and shifting, thereby improving the safety and stability of the battery module.

[0018] Secondly, the end plate is made of engineering plastic and has weight-reducing grooves, which significantly reduces the weight of the battery module and lightens the overall burden; the end plate integrates the functions of metal end plate and plastic bracket, simplifying the structure and reducing complexity;

[0019] In addition, insulating rubber is applied to the surface of the fixing strap to prevent scratching the battery cells and ensure battery performance and lifespan. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] Please see Figure 1-3 A battery module mounting structure includes a battery box and a battery module 2. The battery box includes a base 110, which includes a base plate 111, a crossbeam 112, and a horizontal beam 113. The crossbeam 112 and the horizontal beam 113 are fixedly installed on the top of the base plate 111. The horizontal beam 113 is arranged along the length of the base plate 111, and the end of the horizontal beam 113 is provided with a crossbeam 112. Adjacent crossbeams 112 and adjacent horizontal beams 112 form a placement groove 114 for placing the battery module 2. The lower end of the battery module 2 is located in the placement groove 114.

[0025] The battery module 2 includes a plurality of spaced-apart cells 201, with spacer plates 202 between adjacent cells 201, and end plates 3 at both ends of the battery module 2.

[0026] The end plate 3 is fixedly installed on the top of the crossbeam 112 by fixing screws 304;

[0027] Specifically, the top of the crossbeam 112 is provided with a nut mounting groove, and a fixing nut 302 is fixedly installed in the nut mounting groove; countersunk holes 303 are provided at both the front and rear ends of the end plate 3, and fixing screws 304 pass through the countersunk holes 303 and are threadedly connected to the fixing nut 302.

[0028] Meanwhile, a fixing strap 305 is also fixedly installed on the periphery of the end plate 3 and the battery module 2.

[0029] Furthermore, a fixing strap slot 306 is provided on the side of the end plate 3, and the fixing strap 305 is accommodated in the fixing strap slot 306 for fixing the end plate 3 and the battery cell 201; the fixing strap slot 306 provided on the end plate 3 can be directly used to restrain the fixing strap 305 to prevent it from falling.

[0030] In this solution, the fixing band 305 is a stainless steel band, and an insulating rubber sleeve 307 is fixed on the surface of the fixing band 305 that contacts the battery cell 201. The insulating rubber sleeve 307 mainly serves to prevent the stainless steel band from scratching the battery cell.

[0031] In this solution, the end plate 3 is made of engineering plastic, which can effectively reduce the weight of the end plate; several weight-reducing grooves 308 are vertically opened on the end plate 3 to further reduce the weight of the end plate.

[0032] When this solution is put into use, it can reduce the weight and structural complexity of the battery module. Simultaneously, the use of a crossbeam 112 and a horizontal beam to form a placement groove 114 for the battery module 2, placing the battery module within the placement groove 114, greatly improves the stability of the battery module during installation. The end plate directly integrates the functions of a metal end plate and a plastic bracket, not only limiting cell expansion, but also allowing the fixing strap slot 306 on the end plate to constrain the fixing strap 305, solving the problem of the fixing strap 305 sliding up and down; this enhances the overall structural strength of the battery module. The structural heat-conducting component is located at the bottom of the battery module and between the two fixing tubes.
