[0002] Lithium-ion batteries (LIBs) are widely used in portable electronics, electric vehicles, and energy storage systems due to their high energy density, good cycle performance, and no memory effect.

[0003] In addition to the electrical performance of lithium-ion batteries, their structural strength and production costs are also key points and challenges in their research and application. For example, in the field of RF remote-controlled models, lithium-ion batteries are configured as battery modules. These modules have wires attached to them. To power the model, the module is installed on the model and connected to the model via wires. To charge, the module is removed from the model and connected to a charger via wires. As can be seen, battery modules require frequent installation and removal during use, making their protective performance extremely important.

[0004] At present, battery modules with protection capabilities usually include a battery body, wires and protective components. Among them, the head of the battery module connected to the wire has higher strength requirements. At the same time, as the requirements for the appearance and product size space during product use become more and more stringent, the protection problem of the battery module head will further affect the consistency of the battery module appearance. In the prior art, in order to implement head protection and maintain the consistency of the wire appearance, during molding, the wire is first supported by filling with foam, and then fixed and protected with the help of barley paper and fiber glue. However, the problem with this method is that the head occupies more space, the battery module size becomes longer, the product uses more materials, and the product production process is more, which affects the product efficiency and cost.

[0005] In summary, the battery modules on the market have poor consistency in appearance and usage, and low processing efficiency. Utility Model Content

[0006] In order to solve the problems existing in the prior art, the main purpose of the present invention is to provide a battery protection component and a battery module that are convenient for fixing the wiring harness.

DETAILED DESCRIPTION

[0028] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figures 1 to 4 As shown, a battery protection component that facilitates the fixing of a wire harness according to an embodiment of the present utility model.

[0030] In a simple embodiment, the battery protective member includes a first protective shell and a second protective shell. One side edge of the first protective shell can be spliced ​​to a side edge of the second protective shell. A notch 31 is provided on the first protective shell at the spliced ​​edge. When the first and second protective shells are spliced ​​together, they form a closed fixing hole 50.

[0031] When the battery protective component of this embodiment is applied to a battery with a wire, the first protective shell and the second protective shell are installed on the wire side of the battery. The first protective shell and the second protective shell are spliced ​​together to surround the wire within the closed fixing hole 50, thereby fixing the wire. The wire can be welded and then spliced ​​to avoid the protective shell being unable to pass through the wire terminal after welding the wire.

[0032] In a specific solution of this embodiment, the battery protective component includes a first protective shell and a second protective shell. The first protective shell and the second protective shell have identical shapes and structures, so that the first protective shell and the second protective shell can be obtained simultaneously through a single processing, thereby reducing costs and increasing efficiency.

[0033] Generally speaking, reference Figure 3 and Figure 4The battery body 60 is composed of a plurality of thin-plate-shaped battery cells 62 stacked in sequence to form a rectangular parallelepiped shape. Usually, the battery cells 62 are welded in series to form a sufficient voltage. The connecting wire 61 is welded on top of the battery body 60. The connecting wire 61 usually includes a positive wire and a negative wire. In a battery module with a balanced charging function, the connecting wire 61 usually also includes a node line leading from the two battery cells 62 in series. It can be understood that the welding positions of the positive wire, the negative wire and the node line are different. If the connecting wire 61 is not constrained, it will easily cause the position of the positive wire, the negative wire and the node line to move, resulting in inconsistent product appearance.

[0034] To this end, in the specific scheme of this embodiment, the notch structure 31 of the first protective shell is set to be offset toward the right side relative to the midpoint of the splicing edge, and the notch structure 31 is not set at the position where the first protective shell is offset toward the left side relative to the midpoint of the splicing edge. Since the shape and structure of the first protective shell and the second protective shell are exactly the same, when the first protective shell and the second protective shell are docked, the notch structure 31 of the first protective shell on the right side is docked to the second protective shell with a straight edge on the left side, forming a closed fixing hole 50. The closed fixing hole 50 can constrain, for example, the positive line and one of the node lines. The straight edge of the first protective shell on the left side is docked to the notch structure 31 on the right side of the second protective shell, forming another closed fixing hole 50. The closed fixing hole 50 can constrain, for example, the negative line and another node line. It can be seen that the first protective shell and the second protective shell with the same structure can form two matching closed fixing holes 50.

[0035] To this end, in the specific solution of this embodiment, upright retaining seats 34 are symmetrically provided on either side of the midpoint of the splicing edge of the first protective shell. The left retaining seat 34 is provided with a retaining post 32 extending in the splicing direction, while the right retaining seat is provided with a retaining hole 33 extending in the splicing direction. Because the first and second protective shells have identical shapes and structures, when the first and second protective shells are docked, the retaining post 32 on the left side of the first protective shell docks with the retaining hole 33 on the right side of the second protective shell, and the retaining hole 33 on the right side of the first protective shell docks with the retaining post 32 on the left side of the second protective shell. The retaining post 32 has a smaller diameter on the top side and a larger diameter on the base side, allowing it to snap into the retaining hole 33. Thus, the first and second protective shells, with identical structures, can form a matching retaining structure, facilitating their securement.

[0036] To this end, in the specific solution of this embodiment, vertical partitions 35 are respectively provided on the inner surface of the first protective shell and the inner surface of the second protective shell. The partitions 35 are located at the midpoint of the splicing edge and extend laterally to prevent the connecting wires 61 from sliding.

[0037] To this end, in this embodiment, reinforcing ribs 36 are provided on the inner surfaces of the first and second protective shells, respectively. The inner surfaces of the first and second protective shells face the battery body 60. The reinforcing ribs 36 are arranged in the horizontal and vertical directions, making the first and second protective shells more resistant to deformation, allowing for a thinner design and greater material savings.

[0038] To this end, in the specific embodiment of this invention, the first protective shell is approximately rectangular in shape, and the second protective shell is also approximately rectangular in shape. The shape of the first and second protective shells after splicing matches the top and side shapes of the battery body 60. The right side of the first protective shell is the splicing edge, and the left, top, and bottom sides of the first protective shell are each provided with a folded edge 40. The first and second protective shells have identical shapes and structures, and therefore, the second protective shell is provided with a folded edge 40 on all edges except the splicing edge.

[0039] like Figure 5 and 6 FIG. 1 shows a battery module according to an embodiment of the present invention. The battery module includes a battery body 60 and a connecting wire 61 welded to the battery body 60. The connecting wire 61 also includes the aforementioned battery protective member for facilitating wiring harness fixation. The connecting wire 61 is fixed within a closed fixing hole 50 formed by the first and second protective shells.

[0040] It can be seen that the first protective shell and the second protective shell can be spliced ​​on the side of the battery body 60 with the connecting wire 61. A notch structure 31 is provided at the splicing edge of the first protective shell. After splicing, the connecting wire 61 is constrained within the closed fixation formed by the first protective shell and the second protective shell. On the basis of ensuring that the head of the battery module is protected, the appearance consistency of the head wire is effectively guaranteed during use. At the same time, it has the characteristics of saving production materials, convenient processing and assembly, reducing processes, improving production efficiency, reducing processing costs and increasing product competitiveness.

[0041] In addition, the battery module also includes a main protective plate 63, a fixing belt 64, a foam bottom plate 65, a protective bottom plate 66 and an outer protective sleeve 67. The battery body 60 is formed by stacking at least two battery cells 62 in sequence to form a rectangular parallelepiped. The connecting wire 61 is welded to the electrode on the top side of the battery body 60. The first protective shell and the second protective shell are fixed to the top side of the battery body 60 to fix the wiring harness and protect the top. The main protective plate 63 is configured in two and is fixed to the front and back sides of the battery body 60 respectively to protect the front and back of the battery. The fixing belt 64 surrounds the outside of the battery body 60 to which the main protective plate 63 is fixed, and it fixes the main protective plate 63. The foam bottom plate 65 is fixed to the bottom side of the battery body 60, and the protective bottom plate 66 is fixed to the bottom side of the foam bottom plate 65 to protect the bottom. The outer protective sleeve 67 is sleeved on the outermost layer of the battery body 60 and is adhered to the outermost layer of the battery body 60 by heat shrinkage.

[0042] It can be seen that the battery module of the present invention has excellent protection performance and good appearance consistency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention.
