Description

Technical Field

[0001] The utility model relates to a bar fixing structure, in particular to a bar fixing structure on an energy storage battery. Background Art

[0002] New energy vehicles rely on high-capacity power batteries as their energy storage units, which are usually composed of many individual battery cells. When forming a power battery pack, the independent battery cells must be connected in series and parallel through electrical connectors and mounted on injection molded isolation boards to ensure the electrical connection and mechanical stability of the battery pack. In addition, the design of the isolation board must also support the integration of micro-current circuits such as voltage detection and temperature detection required for battery performance monitoring.

[0003] Currently, most CCS (Cell Contact System, integrated busbar or wiring harness board integration) components on the market use a bar fixing method that reserves corresponding space on the isolation board for installation. During the design process, the size of the isolation board must be large enough to cover the bar to ensure that there is enough space for the bar to be fixed. Although this design ensures the fixation and connection of the battery cell, it also leads to an increase in the material used in the isolation board and an increase in the weight of the product, which to some extent affects the overall performance and energy efficiency of new energy vehicles.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The utility model discloses a bar fixing structure on an energy storage battery.

[0022] Embodiment 1;

[0023] like Figure 1 and Figure 3 As shown, including:

[0024] Isolation plate 1, a planar rectangular plate structure;

[0025] The limit group 2 includes six protruding portions on the isolation plate 1 such as Figure 5 The U-shaped plate bodies 3 shown in the figure are divided into two symmetrical groups, each group has three U-shaped plate bodies 3, and the U-shaped plate bodies 3 in each group are arranged at intervals on the edge of the isolation plate 1, and the interval distance is determined according to the width of the connected bar sheet. In other embodiments, the number of U-shaped plate bodies can be specifically set according to the size of the isolation plate 1. The same is that the two symmetrical groups of U-shaped plate bodies are surrounded by the isolation plate 1 to form an FPC limit card slot 4, and the FPC limit card slot 4 is used to clamp the FPC component. The adjacent U-shaped plate bodies in each group are arranged at an interval of 1:1. The U-shaped plate body 3 and the isolation plate 1 are surrounded to form a bar piece limiting slot 5, which is used to clamp the bar piece. The FPC limiting slot 4 and the bar piece limiting slot 5 are interconnected; the two are interconnected to realize the connection between the bar piece and the FPC component; it should be noted that the bar piece limiting slot 5 serves as a slot for connecting the bar piece, and can be two adjacent slots that jointly clamp the same bar piece with two interfaces, or can be a slot that independently clamps a bar piece, thereby reducing the material used in the isolation plate and reducing the weight of the overall product.

[0026] The first limiting protrusion 6 is in a square shape and connected to the middle of one side of the U-shaped plate 3. The first limiting protrusion 6 extends laterally above the corresponding bar piece limiting slot 5. At the same time, there is a gap between the first limiting protrusion 6 located above the bar piece limiting slot 5 and the isolation plate 1. This gap is used to clamp the bar piece 10 in the upper and lower positions, thereby playing a role in stabilizing the bar piece;

[0027] The second limiting protrusion 7 is connected to the U-shaped plate 3 and is also in a square shape. The second limiting protrusion 7 extends laterally above the corresponding second limiting protrusion 7. There is a gap between the second limiting protrusion 7 located above the FPC limiting slot 4 and the isolation plate 1. This gap is used to clamp the FPC assembly 13 in the upper and lower positions.

[0028] Therefore, this embodiment adopts a slot limiting structure to fix the bar, and by fixing the FPC without hot riveting, it reduces the material used in the isolation plate, reduces the weight of the overall product, reduces the investment in hot riveting equipment during the production process, and effectively reduces product costs.

[0029] Embodiment 2:

[0030] like Figure 2 and Figure 4As shown, different from the first embodiment, in this embodiment, in order to further stabilize the FPC assembly 13, a plurality of vertical FPC limit posts 8 are provided in the FPC limit slot 4, and the plurality of FPC limit posts 8 are arranged in a line in the FPC limit slot, and the positions of the FPC limit posts 8 and the second limit protrusions 7 correspond to each other, and the FPC limit posts 8 are penetrated in the FPC assembly 13.

[0031] In order to further stabilize the bar, a buckle 9 is provided on the isolation plate 1 in the bar limiting slot 5, and the buckle 9 is engaged with the bayonet 11 on the bar 10 installed in the bar limiting slot 5. The buckle 9 is located at the edge of the isolation plate 1 and is integrally connected to the isolation plate 1 through the root. Through grooves 12 are opened on the isolation plate 1 on both sides of the buckle 9. The buckle 9 is engaged with the bayonet 11, and cooperates with the first limiting protrusion 6 above the bar limiting slot 5 to achieve the effect of further stabilizing the clamped bar.

[0032] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
