By setting a foggy semi-transparent silica gel cap on the upper end of the upper cover arranged below the LED light-transmitting holes opened on the surface of the LED indicator panel, and the foggy semi-transparent silica gel cap has both light-transmitting and waterproof functions, so as to play a waterproof sealing role through the foggy semi-transparent silica gel cap and squeeze the foggy semi-transparent silica gel cap when a large amount of heat is generated in the battery pack, so that the hot air inside the battery pack is discharged from the gap, so as to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A battery LED indicator structure with a waterproof and breathable function, including a battery upper cover and a battery lower cover. The battery upper cover is arranged above the battery lower cover. The surface of the battery upper cover is provided with an LED indicator panel. A plurality of LED light-transmitting holes are opened on the surface of the LED indicator panel. A waterproof and breathable mechanism is further arranged inside the battery lower cover at the bottom of the LED indicator panel;

[0007] The waterproof and breathable mechanism includes a foggy semi-transparent silica gel cap. The foggy semi-transparent silica gel caps are all sleeved on the top of the upper cover. The upper covers are respectively arranged below a plurality of LED light-transmitting holes opened on the surface of the LED indicator panel.

[0008] Preferably, the foggy semi-transparent silica gel cap is sleeved on the upper part of the upper cover and has a tight interference fit with the upper cover.

[0009] Preferably, the foggy semi-transparent silica gel cap expands and contracts between the upper cover and the LED indicator panel.

[0010] Preferably, a PCB board is further arranged inside the battery lower cover below the upper cover. SMD LEDs are symmetrically arranged on the surface of the PCB board below the upper cover.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0022] A battery LED indicator structure with waterproof and breathable functions, including a battery upper cover 1 and a battery lower cover 2. The battery upper cover 1 is arranged above the battery lower cover 2. An LED indicator panel 3 is arranged on the surface of the battery upper cover 1. A plurality of LED light-transmitting holes 4 are opened on the surface of the LED indicator panel 3. A waterproof and breathable mechanism is further arranged at the bottom of the LED indicator panel 3 inside the battery lower cover 2;

[0023] The waterproof and breathable mechanism includes a foggy translucent silica gel cap 8. The foggy translucent silica gel caps 8 are all sleeved on the top of the upper cover 7. The upper covers 7 are respectively arranged below a plurality of LED light-transmitting holes 4 opened on the surface of the LED indicator panel 3.

[0024] By arranging an LED indicator panel 3 on the surface of the battery upper cover 1, and a plurality of LED light-transmitting holes 4 are opened on the surface of the LED indicator panel 3. A plurality of upper covers 7 are respectively arranged below the LED light-transmitting holes 4. Foggy translucent silica gel caps 8 are respectively arranged at the tops of the upper covers 7. The foggy translucent silica gel caps 8 are sleeved above the upper covers 7 and are in tight interference fit with the upper covers 7. So as to be in interference fit through the foggy translucent silica gel caps 8 and the upper covers 7, and to waterproof and protect the upper covers 7 through the foggy translucent silica gel caps 8, avoiding external water sources from entering the inside of the battery lower cover 2 through the LED light-transmitting holes 4, achieving the effect of sealing and waterproofing.

[0025] The foggy translucent silica gel cap 8 expands and contracts between the upper cover 7 and the LED indicator panel 3. By arranging the foggy translucent silica gel cap 8 between the LED indicator panel 3 and the upper cover 7, and the foggy translucent silica gel cap 8 is in interference fit with the upper cover 7 under normal conditions, so as to seal and waterproof the inside of the battery through the foggy translucent silica gel cap 8. When a large amount of heat is generated inside the battery, the foggy translucent silica gel cap 8 is squeezed and deformed, generating a gap with the upper cover 7, achieving the effect of exhausting air and relieving pressure, enabling the battery to have the ability to exhaust air and relieve pressure, replacing the function of the waterproof and breathable valve, and achieving the effect of reducing costs without sacrificing battery safety.

[0026] Below the upper cover 7 and inside the battery lower cover 2, there is also a PCB board 5 arranged.

[0027] On one side inside the battery upper cover 1 and the battery lower cover 2, there are multiple groups of battery packs 11 arranged, and the multiple groups of battery packs 11 are linearly connected to the LED indicator panel 3. By arranging multiple groups of battery packs 11 on one side inside the battery upper cover 1 and the battery lower cover 2, and linearly connecting the multiple groups of battery packs 11 to the LED indicator panel 3, it is convenient to energize the multiple groups of battery packs 11 and the LED indicator panel 3, so as to display the temperature, power, etc. of the multiple groups of battery packs 11 through the LED indicator panel 3.

[0028] The state where the foggy translucent silicone cap 8 is normally sleeved above the upper cover 7 is the normal state 9 of the silicone cap. The state where the foggy translucent silicone cap 8 is squeezed after the battery generates a large amount of heat is the abnormal state 10 of the silicone cap.
