DETAILED DESCRIPTION

[0022] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0023] This embodiment provides a battery power display structure, such as Figure 1-6 As shown, it is applied to a battery pack. The battery pack mainly includes a housing 100, a battery installed in the housing 100, and a power display structure. The power display structure includes an upper cover 200, a power board 300, and a light guide 400. The power board 300 is fixed to the upper cover 200 by screws, and the upper cover 200 is covered on the housing 100. The power board 300 is provided with a power button 320 and multiple indicator lights 310. The light guide 400 includes a light guide panel 420 and multiple light guide columns 410 connected to the light guide panel 420. The multiple light guide columns 410 correspond to the multiple indicator lights 310. The upper cover 200 has multiple mutually spaced first mounting holes 210. The multiple light guide columns 410 are respectively inserted into the multiple first mounting holes 210. The light guide panel 420 covers the top of the first mounting holes 210. The light guide panel 420 is sealed and welded to the upper cover 200. This embodiment takes three indicator lights 310 corresponding to three light guides 410 and three first mounting holes 210 as an example. The number of indicator lights 310 can show the power status. The indicator lights 310 emit light, and the light passes through the corresponding light guides 410 to the conduit panel, so that the corresponding area of ​​the light guide panel 420 emits light. The light guide panel 420 covers the first mounting hole 210 and is ultrasonically sealed and welded to the upper cover 200 to improve the sealing performance of the battery pack and reduce the risk of water ingress.

[0024] like Figure 5-7 As shown, the lower surface of the light guide panel 420 has a welding rib 421, the upper cover 200 has a mounting groove 220, the light guide panel 420 is embedded in the mounting groove 220, and the welding rib 421 is sealed and welded to the bottom of the mounting groove 220. In this way, while ensuring the sealing of the connection position, it is beneficial to improve the flatness of the top of the battery pack.

[0025] like Figure 5 , 6 As shown, the power panel 300 is provided with a button 320, the upper cover 200 is provided with a second mounting hole 230, the button 320 is penetrated through the second mounting hole 230, the upper cover 200 is provided with an annular groove 240 surrounding the second mounting hole 230, and the hole wall of the second mounting hole 230 protrudes upward from the bottom wall of the annular groove 240. A small amount of water will not directly flow into the second mounting hole 230, but will be collected in the annular groove 240, thereby improving the waterproof capability of the power display structure.

[0026] like Figure 6 As shown, an elastic keycap 500 is sleeved on the upper end of the hole wall of the second mounting hole 230, and the keycap 500 is sealed with the inner wall of the annular groove 240, and the keycap 500 is in contact with the key 320. Pressing the keycap 500 can touch the key 320, and pressing the key 320 can trigger the corresponding indicator light 310 on the power board 300 to light up, thereby displaying the power status. The keycap 500 can also prevent water in the annular groove 240 from entering the battery pack through the second mounting hole 230.

[0027] like Figure 6-8 As shown, the cross section of the light guide column 410 is trapezoidal, and the angle between the side of the light guide column 410 close to the button 320 and the vertical line is smaller than the angle between the side of the light guide column 410 away from the button 320 and the vertical line. When the power board 300 is small, the distance between the button 320 and the indicator light 310 is short, the distance between the first mounting hole 210 and the second mounting hole 230 can be increased, the width of the plastic between the first mounting hole 210 and the second mounting hole 230 can be increased, and the strength of the upper cover 200 can be increased.

[0028] like Figure 5 , 7 As shown in FIG. 8 , there are spacing ribs 250 between adjacent first mounting holes 210, and the light guide panel 420 has a spacing groove 422 located above the spacing ribs 250. This can make the power display of the light guide panel 420 more distinguishable, and can reduce the interference of light transmitted from different light guide columns 410 to the light guide panel 420.
