Description

Technical Field

[0001] This utility model relates to the field of heating films, and in particular to a battery heating film with uniform heating. Background Technology

[0002] A heating film is a thin film material that can generate heat. It is usually composed of conductive materials and high-temperature stable polymers. When an electric current is applied, the heating film generates heat energy and transfers the heat energy to nearby objects or space, thereby achieving the purpose of heating.

[0003] Existing heating films typically consist of two film bodies and a heating resistance wire. When using heating films in batteries, they are usually installed by pasting or directly attaching them to the outside of the battery. This can cause the heating film to loosen and fall off during use, which not only reduces the stability of the installation but also reduces the heating efficiency of the battery, thus presenting certain defects.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] This utility model provides, for example Figure 1-3The battery heating film shown includes a base film 1, a heating unit 2, a mounting assembly 3, a heat insulation layer 4, and thermally conductive silicone 5. The heating unit 2 is disposed on top of the base film 1 and is powered on for heating. The mounting assembly 3 is disposed on top of the base film 1 and is used to install and protect the heating unit 2. The heat insulation layer 4 is connected between the base film 1 and the heating unit 2 and is used to reduce heat loss from the heating unit 2. The heat insulation layer 4 is made of aerogel material, which is a material with extremely low thermal conductivity and excellent heat insulation performance, thereby reducing heat loss from the side of the heating unit 2 away from the battery. The thermally conductive silicone 5 is connected to the top of the heating unit 2 and is used to transfer the heat generated by the heating unit 2 to the heated object. The thermally conductive silicone 5 is made of silicone and thermally conductive materials, giving it good thermal conductivity. That is, the heating unit 2 transfers heat to the thermally conductive silicone 5, which in turn transfers heat to the battery, thereby improving the uniformity of heating the battery by the heating unit 2.

[0039] Furthermore, the heating unit 2 includes a first connecting film 21, a second connecting film 22, and a resistance wire 24. The first connecting film 21 is connected to the top of the heat insulation layer 4, the second connecting film 22 is connected to the top of the first connecting film 21, and the resistance wire 24 is equidistantly connected between the first connecting film 21 and the second connecting film 22. The heating unit 2 also includes a terminal block 23 and a wire 25. The terminal block 23 is connected to the side between the first connecting film 21 and the second connecting film 22. The end of the resistance wire 24 is electrically connected to the terminal block 23, and one end of the wire 25 is electrically connected to the terminal block 23. Multiple resistance wires 24 are connected in parallel between two terminal blocks 23, so that if one resistance wire 24 breaks, it will not affect the energization and heating of the resistance wire 24, thereby improving its durability.

[0040] Furthermore, the mounting assembly 3 includes a connecting plate 31, a first wire 32, a second wire 33, and a clamping unit 34. The connecting plate 31 is connected to the top of the base film 1, and one side of the connecting plate 31 is attached to the heating unit 2. The first wire 32 is connected between the heat insulation layer 4 and the heating unit 2, and the second wire 33 is connected between the heating unit 2 and the thermally conductive silicone 5. The clamping unit 34 is disposed inside the connecting plate 31. The first wire 32 and the second wire 33 are both connected to the connecting plate 31 through the clamping unit 34. The connecting plate 31 can be installed at the battery heating part, thereby mounting the heating unit 2 through multiple first wires 32 and multiple second wires 33. In addition, the multiple first wires 32 and multiple second wires 33 can also improve the tensile strength of the end of the heating unit 2.

[0041] Example 2

[0042] Based on Example 1, such as Figure 4As shown, the clamping unit 34 includes a first clamping block 341, a second clamping block 342, and a cable tray. The bottom of the connecting plate 31 is provided with a connecting groove that matches the first clamping block 341 and the second clamping block 342. The cable tray is located on one side of the connecting plate 31. One end of the first wire 32 and one end of the second wire 33 pass through the cable tray and are clamped between the first clamping block 341 and the second clamping block 342, so that the first clamping block 341 and the second clamping block 342 are engaged in the connecting groove. The base film 1 is connected to the bottom of the connecting plate 31, which can also ensure the stability of the first clamping block 341 and the second clamping block 342 installed in the connecting groove.

[0043] Furthermore, the clamping unit 34 also includes a groove, a pressing block 343, and a positioning rod 344. The groove is formed on the opposite side of the first clamping block 341 and the second clamping block 342. One end of the first wire 32 and one end of the second wire 33 are respectively located inside the groove. The pressing block 343 is fixedly connected to the inside of the groove. The outer wall of the pressing block 343 is pressed and adhered to the first wire 32, so that the first clamping block 341 and the second clamping block 342 can clamp and fix the first wire 32 and the second wire 33 through the pressing block 343, thereby ensuring the stability of the connection between the first wire 32 and the second wire 33 and the connecting plate 31. The positioning rod 344 is fixedly connected to the top of the inner wall of the connecting groove. The top of the first clamping block 341 and the second clamping block 342 are provided with positioning holes that match the positioning rod 344. The positioning rod 344 can improve the stability of the first clamping block 341 and the second clamping block 342 installed in the connecting groove.
