[0017] The following is combined with Figure 1-4 The present invention is further described in detail with reference to the following specific embodiments, but they are not intended to limit the present invention:

[0018] Example 1

[0019] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a heat preservation bag structure for a single lead-acid battery includes a heat preservation bag body 1 and a lead-acid battery 2. The heat preservation bag body 1 includes a non-woven fabric 11, a flame-retardant hot air cotton 12 and an aluminized polyester film 13 from the inside out. An installation space 14 is provided on the heat preservation bag body 1, and the lead-acid battery 2 is installed in the installation space 14.

[0020] Specifically, the non-woven fabric 11 has the characteristics of being moisture-proof, breathable, flexible, thin, flame-retardant, non-toxic and odorless, inexpensive, and recyclable, and can effectively control the weight and insulation of the electric vehicle while achieving heating and heat preservation of the lead-acid battery 2;

[0021] The flame retardant hot air cotton 12 is formed by hot air passing through a furnace after being laid out, and has the characteristics of being flame retardant, fireproof, lightweight, warm, durable, and environmentally friendly, and plays a flame retardant role in the heating and heat preservation process of the lead-acid battery 2;

[0022] The aluminized polyester film 13 has high bonding strength, good bonding effect, no water leakage and good puncture resistance and self-healing performance. It plays an anti-vibration and anti-friction effect on the frame joint surface and prevents moisture from entering the insulation bag body 1.

[0023] Preferably, at least two flame-retardant non-woven fabrics 15 are further included, and the flame-retardant non-woven fabrics 15 are respectively arranged on the left and right sides of the heat-insulating bag body 1 .

[0024] Preferably, a locking device 3 is further included, which includes an elastic band 31 and a rotating button 32. The rotating button 32 is arranged at the front end of the heat-insulating bag body 1. The elastic band 31 is put on the heat-insulating bag body 1 and is connected to the rotating button 32.

[0025] Preferably, at least one wiring hole 16 is further provided at the rear end of the heat-insulating bag body 1 .

[0026] Specifically, when using the present invention, the lead-acid battery 2 is first placed in the installation space 14 of the thermal insulation bag body 1, and then the rotating button 32 of the locking device 3 is rotated to tighten the elastic band 31, so that the thermal insulation bag body 1 is close to the outer wall of the lead-acid battery 2, and finally the positive and negative poles of the lead-acid battery 2 are connected through the wiring hole 16.

[0027] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made within the scope of the patent application for the present invention should fall within the scope of the present invention.
