Description

Technical Field

[0001] The utility model relates to the technical field of automobile battery accessories, in particular to an automobile power lithium battery heating film component. Background Art

[0002] A lithium battery is an electrochemical battery composed of a positive electrode material, a negative electrode material and an electrolyte. During the charging and discharging process of a lithium battery, lithium ions move from the positive electrode to the negative electrode to generate current and heat. If the lithium battery is in a low temperature environment, the electrochemical reaction rate slows down, so its operating temperature needs to be increased to optimize its performance. Therefore, a lithium battery heating film is used to increase the operating temperature of the lithium battery by heating, so that it can operate in a wider temperature range to improve the efficiency and performance of the battery.

[0003] Most of the lithium battery heating films in the prior art are directly fixedly connected to the battery body. Since the battery will expand slightly during use, the resistance wire on the heating film may be squeezed and pulled and broken or damaged, which increases maintenance costs. In addition, the prior art is not convenient for disassembly of the heating mold, and is not convenient for inspection and replacement, which reduces practicality. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an automotive power lithium battery heating film assembly.

[0005] The embodiment of the utility model provides a heating film assembly for a lithium-ion battery in an automobile, comprising:

[0006] A battery body, with heating film bodies disposed on both sides of the battery body, and mounting components disposed on both heating film bodies;

[0007] The mounting assembly includes a U-shaped guard plate, a movable plate, a rubber pad and a plurality of first springs. A fixing assembly is arranged between both ends of the U-shaped guard plate and the battery body. The movable plate is arranged in the U-shaped guard plate. One ends of a plurality of the first springs are fixedly arranged on the inner side of the U-shaped guard plate. The other ends of a plurality of the first springs are fixedly arranged on the movable plate. The rubber pad is fixedly arranged on the other side of the movable plate. The heating film body is adhered to the other side of the rubber pad. The heating film body is arranged against the battery body.

[0008] Furthermore, the fixing assembly includes a fixing plate, a mounting plate, a clamping column and a second spring, the fixing plate is fixedly set at one end of the U-shaped guard plate, the mounting plate is fixedly set at one side of the battery body, a slide groove is penetrated in the mounting plate, the clamping column slides through the top of the mounting plate and extends into the slide groove, a limit block is fixedly set on the top of the clamping column, one end of the second spring is fixedly set at the bottom of the limit block, the other end of the second spring is fixedly set on the top of the mounting plate, and a clamping hole is set on the fixing plate.

[0009] Furthermore, the bottom end of the clamping column is arranged in an inclined surface, and the clamping column is inserted into the clamping hole to be matched.

[0010] Furthermore, a positioning block is fixedly arranged in the slide groove, the positioning block is arranged to abut against a fixed plate, and the fixed plate is arranged to abut against and slide against an inner wall of the slide groove.

[0011] Furthermore, pressing plates are fixedly provided at both ends of the movable plate, and the two pressing plates are both extended out of the U-shaped guard plate.

[0012] Furthermore, one end of the two heating film bodies is connected to a wire, and the other end of the two wires is connected to a connector.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. An installation component is set up. After the heating film body is installed, the U-shaped guard plate can protect the heating film body, and the rubber pad can buffer the heating film body, so that when the battery body expands during use, the heating film body can still fit the battery body well, avoiding the resistance wire on the heating film body from being squeezed and pulled, resulting in breakage or damage.

[0015] 2. A fixing component is provided, and the movable plate can be pulled inward by two pressing plates, and a plurality of first springs can be squeezed. The heating film body can be driven to move inward by the rubber pad, and then the two fixing plates are respectively inserted into the corresponding slide grooves from one end of the mounting plate on the same side, and the inclined surfaces of the corresponding clamping columns are squeezed, so that the two clamping columns can be pushed outward and the two second springs can be stretched. When the two clamping holes are moved to be aligned with the clamping columns on the same side, the two clamping columns can be reset under the action of the corresponding second springs and clamped into the corresponding clamping holes to position the U-shaped guard plate. Finally, the two pressing plates are released to make the heating film body abut against the battery body, so that the heating film body is installed and fixed; the two clamping columns are pulled outward to separate the two clamping columns from the corresponding clamping holes, and the two fixing plates can be pulled out to disassemble the heating film body.

[0016] To sum up, the utility model is provided with an installation component, which can prevent the resistance wire on the heating film body from being squeezed and pulled and caused to break or damage, thereby reducing maintenance costs. A fixing component is also provided, which can quickly and conveniently install and disassemble the heating film body, facilitate maintenance and replacement, and improve work efficiency.
