Some battery packs with relatively compact structures are not suitable for installing power display boards due to their small design size. Utility Model Content

[0003] In view of the above-mentioned defects of the prior art, an object of the present invention is to provide a battery pack with oblique light guiding.

[0004] The technical solution of the utility model is: a battery pack with oblique light guidance, including an outer shell, a control board installed in the outer shell, a plurality of power display lights installed on the outer edge of the top of the control board, a light blocking column installed on the outer shell, a light guiding column fixed on the light blocking column, the light guiding column is located outside the power display light, the light guiding column is composed of a first horizontal section, an inclined section and a second horizontal section distributed from the inside to the outside, the inner side surface of the first horizontal section is a light incident surface located outside the power display light, and the outer side surface of the second horizontal section is a light emitting surface.

[0005] Furthermore, a plurality of card blocks are provided on the light blocking column, and a plurality of card slots are provided on the light guiding column, and the card blocks are inserted into the card slots.

[0006] Furthermore, the inner end of the inclined section is higher than the outer end thereof.

[0007] Furthermore, the light emitting surface is exposed outside the side wall of the housing.

[0008] The application of the oblique light-guiding battery pack provided by the utility model has the beneficial effect that the power indicator light is mounted on the control panel and can be applied to a battery pack with a relatively compact structure in combination with the light-guiding column capable of oblique light-guiding.

DETAILED DESCRIPTION

[0014] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0015] like Figure 1 — Figure 4 As shown, Figure 4 The pointed end in the figure represents the direction of light radiation. A battery pack with oblique light guiding comprises a shell 1, a control board 2 is installed in the shell 1, a plurality of power indicator lights 3 are installed on the top outer edge of the control board 2, a light blocking column 4 is installed on the shell 1, a light guiding column 5 is fixed on the light blocking column 4, the light guiding column 5 is located on the outside of the power indicator light 3, and the light guiding column 5 is composed of a first horizontal section 51, an inclined section 52 and a second horizontal section 53 distributed from the inside to the outside, the inner side surface of the first horizontal section 51 is a light incident surface 511 located on the outside of the power indicator light 3, and the outer side surface of the second horizontal section 53 is a light emitting surface 531.

[0016] like Figure 2 and Figure 3 As shown, in order to conveniently fix the light guiding column 5 , a plurality of clamping blocks 41 are provided on the light blocking column 4 , and a plurality of clamping grooves 54 are provided on the light guiding column 5 , and the clamping blocks 41 are clamped into the clamping grooves 54 .

[0017] like Figure 4 As shown, the inner end of the inclined section 52 is higher than the outer end. The light emitted by the power indicator light 3 enters from the light incident surface 511 and finally exits from the light emitting surface 531 .

[0018] like Figure 1 As shown, the light emitting surface 531 of the light guide column 5 is exposed outside the side wall of the housing 1 .

[0019] The utility model provides a battery pack with oblique light guiding, wherein the power indicator light 3 is installed on the control board 2 and cooperates with the light guiding column 5 which can guide light obliquely, and can be applied to the battery pack with a relatively compact structure.

[0020] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
