Description

Technical Field

[0001] This utility model relates to the technical field of batteries, and more specifically to a cell clamping strip for fixing batteries. Background Technology

[0002] Cell retaining strips are an indispensable part of battery modules. Their main function is to fix the cells in place, ensuring the stability and safety of the battery module. Currently available cell retaining strips have the following shortcomings: First, they are made entirely of steel plates, which have limited capacity to withstand the expansion and contraction forces of the cells during charging and discharging; second, they are heavy, increasing the overall weight of the battery module and thus affecting the energy consumption and driving range of electric vehicles; and third, they only serve the function of fixing the cells. Utility Model Content

[0003] To address the aforementioned shortcomings, this invention provides a battery cell retaining strip. It is lightweight and, while maintaining overall strength, effectively increases rigidity, allowing it to better withstand the expansion and contraction forces of the battery cell during charging and discharging. It not only secures the battery cell but also supports and fixes the upper cover plate.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] The cell pressure bar includes a pressure bar seat, a steel pipe, and a sleeve. The pressure bar seat has a T-shaped cross-section. The steel pipe is fixedly installed on the upper surface of the T-shaped pressure bar seat, and the sleeve is fixedly installed on the steel pipe.

[0006] Preferably, the upper surface of the T-shaped pressure strip seat is provided with a limiting groove, and the steel pipe is fixedly installed in the limiting groove on the upper surface of the pressure strip seat.

[0007] Preferably, the pressure strip seat is made of resin-glass fiber composite material.

[0008] Preferably, the steel pipe has a positioning hole, and the sleeve is fixedly installed in the positioning hole on the steel pipe.

[0009] Preferably, the steel pipe has fixing holes at both ends.

[0010] Preferably, the sleeve has a threaded through hole at its center.

[0011] Preferably, a sealing annular groove is provided on the outer side of the threaded through hole of the sleeve.

[0012] Preferably, the surface of the steel pipe is covered with an insulating film.

[0013] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:

[0014] 1. The pressure strip base is T-shaped and made of resin fiberglass composite material. While ensuring the overall strength of the product, it also helps to reduce the weight of the product. At the same time, the pressure strip base made of resin fiberglass composite material also has good insulation properties.

[0015] 2. Fixing the steel pipe on the pressure strip seat not only helps to improve the overall rigidity of the product, but also helps to reduce the overall weight of the product;

[0016] 3. By fixing a threaded sleeve to the steel pipe, the cover plate above the battery cell can be effectively fixed through the sleeve;

[0017] 4. By covering the surface of the steel pipe with an insulating film, the insulating film can be used to insulate the cover plate above the battery cell. Attached Figure Description

[0019] Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure at point A-A;

[0020] Figure 3 for Figure 1 Schematic diagram of the cross-sectional structure at point B-B. Detailed Implementation

[0021] Depend on Figure 1 , Figure 2 and Figure 3 As shown, the battery cell retaining strip includes a retaining strip base 1, a steel pipe 2, and a sleeve 3. The retaining strip base 1 has a T-shaped cross-section and is made of resin-glass fiber composite material. While ensuring its strength, it reduces the overall weight of the product and also has good insulation performance. A limiting groove 4 is provided on the upper surface of the T-shaped retaining strip base 1. The steel pipe 2 is fixedly installed in the limiting groove 4 on the upper surface of the retaining strip base 1. Because the steel pipe 2 has a hollow structure, it not only helps to reduce the overall weight of the product but also helps to improve the product's rigidity, allowing the product to be more flexible. To better withstand the expansion and contraction forces of the battery cell during charging and discharging, the steel pipe 2 has a positioning hole, and the sleeve 3 is fixedly installed in the positioning hole on the steel pipe 2. The center of the sleeve 3 has a threaded through hole 5, which can be used to quickly and effectively fix the cover plate above the battery cell. The outer side of the threaded through hole 5 of the sleeve 3 has a sealing annular groove 6. An insulating film is covered on the surface of the steel pipe 2. Fixing holes 7 are opened at both ends of the steel pipe 2, and the product is fixedly installed on the base of the battery cell through the fixing holes 7 at both ends.
