In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] This embodiment provides an energy storage power supply, which includes a battery assembly, a housing, and a display assembly. The electronic assembly is placed in the housing, and the display assembly is embedded in the housing. The display assembly is used to convey information such as the charge state, fault condition, and operation condition of the energy storage power supply. Figure 1-Figure 6 As shown, the display assembly includes a light guide structure 10, a light board 20, a waterproof film 30 and a buffer pad 50, wherein the light guide structure 10 is arranged between the light board 20 and the buffer pad 50, the buffer pad 50 is arranged between the light board 20 and the outer shell, the waterproof film 30 is arranged on the side of the buffer pad 50 away from the light guide structure 10, and the waterproof film 30 is attached to the outer side of the outer shell.

[0037] Further, such as Figure 1-Figure 6 As shown, the light guide structure 10 includes a light guide plate 1 and at least two light guide columns 2. The first end of the light guide column 2 is arranged through the light guide plate 1. The first end of the light guide column 2 is set as the light outlet end 21. The second end of the light guide column 2 is set as the light inlet end 22. The periphery of the light guide column 2 is covered with a light shielding layer 3. The light shielding layer 3 can prevent light from penetrating through the periphery of the light guide column 2. Correspondingly, at least two light sources 201 are arranged on the light board 20. The light source 201 is specifically an LED lamp bead. The light source 201 is arranged one-to-one with the light inlet end 22 of the light guide column 2. The waterproof film 30 is provided with a plurality of indicator holes. The indicator holes are arranged corresponding to the light outlet end 21 of the light guide column 2. The light emitted by the light source 201 can be guided to the indicator holes through the light guide column 2.

[0038] Specifically, the light guide structure 10 provided in this embodiment transmits light between the light source 201 and the indicator light hole through the light guide column 2. The light emitted from the light source 201 enters the light guide column 2 through the light inlet end 22, and then exits from the light outlet end 21 to the indicator light hole, so that the indicator light hole is lit. By covering the periphery of the light guide column 2 with a light shielding layer 3, light emitted by other light sources 201 is prevented from penetrating from the periphery of the light guide column 2, thereby greatly reducing the phenomenon of light and color mixing, and no light shielding cover is required, thus saving material costs and reducing assembly time.

[0039] In this embodiment, if Figure 1-Figure 3As shown, there are six light sources 201, light guides 2 and indicator holes, and they are arranged in a straight line at intervals. Each light source 201 guides light to the corresponding indicator hole through a light guide 2. Four adjacent light sources 201 cooperate to indicate the charging state, another light source 201 indicates a fault condition, and the remaining light source 201 indicates the operating condition.

[0040] For example, Figure 1 , Figure 2 and Figure 6 As shown, the light guide column 2 is configured as a double-bending structure, with an intermediate section arranged between the light input end 22 and the light output end 21, and bending angles with the same angle and opposite directions are arranged between the light input end 22 and the intermediate section, and between the light output end 21 and the intermediate section, respectively. The light input end 22 and the light output end 21 are arranged in parallel, so that the light transmission is more uniform, dark areas and bright areas are avoided, and the light source 201 is prevented from being directly exposed.

[0041] For example, Figure 3 and Figure 4 As shown, a light homogenizing portion 5 is provided at the end of the light inlet end 22, and the light homogenizing portion 5 includes a plurality of convex hull units 51 arranged in a matrix, and the convex hull units 51 are set as a transparent structure, and a plurality of light inlet surfaces are provided on the convex hull units 51, and the light inlet surfaces are arranged non-parallel to the end surface of the light inlet end 22. The light emitted by the light source 201 enters the light guide column 2 through the light homogenizing portion 5, and under the action of the plurality of light inlet surfaces, the light entering the light guide column 2 is fully and evenly scattered, further improving the uniformity of light transmission, while preventing the light source 201 from being directly exposed.

[0042] In this embodiment, if Figure 4 As shown, the light-incoming surface is a light-incoming plane 511, and the convex hull unit 51 is provided with at least three light-incoming planes 511 arranged at an angle with the end surface of the light-incoming end 22, and the convex hull unit 51 can be a pyramid, a prism or a prism structure. In other embodiments of the utility model, the light-incoming surface can also be a light-incoming curved surface, and the convex hull unit 51 can be a cone, a truncated cone or a cylindrical structure.

[0043] For example, Figure 2 , Figure 5 and Figure 6 As shown, the light guide column 2 further includes a light-transmitting portion 4, which is arranged at the end surface of the light-emitting end 21 passing through the light guide plate 1, and the light-transmitting portion 4 is set as a transparent structure. Specifically, the light-transmitting portion 4 is set as a cubic structure, and the light-transmitting portion 4 can be embedded in the indicator hole. Since the light-transmitting portion 4 is entirely light-transmitting, light can pass through the top and surroundings of the light-transmitting portion 4. Therefore, after the light source 201 is guided out of the light guide column 2 and enters the light-transmitting portion 4, it can be emitted from the top and surroundings of the light-transmitting portion 4, presenting a three-dimensional luminous effect. Therefore, the user can observe the luminous effect from the front and various oblique sides, and the indication effect is better.

[0044] For example, Figure 3 and Figure 5 As shown, between adjacent light guide columns 2, the light guide plate 1 is provided with a light isolation hole 11, and the hole wall of the light isolation hole 11 is covered with a light shielding layer 3. The provision of the light isolation hole 11 can block the light between adjacent light guide columns 2 from being transmitted through the inside of the light guide plate 1, and the light shielding layer 3 on the hole wall of the light isolation hole 11 can also prevent external light from entering the light guide column 2 after being incident through the hole wall of the light isolation hole 11, thereby further improving the effect of preventing cross-light and cross-color.

[0045] For example, Figure 5 As shown, on a plane perpendicular to the arrangement direction of two adjacent light guide columns 2, the projection of the light isolation hole 11 covers the projection of the light guide column 2 in width, that is, the width of the light isolation hole 11 is wider than the width of the light guide column 2, and the position of the light isolation hole 11 does not deviate from the effective blocking area between the two adjacent light guide columns 2, thereby ensuring the blocking effect of the light isolation hole 11 on the light transmitted in the light guide plate 1.

[0046] For example, Figure 6 As shown, the outer surface of the light guide plate 1 is covered with a light shielding layer 3 to prevent part of the light from entering the light guide column 2 through the light guide plate 1, thereby further improving the effect of preventing cross-light and cross-color.

[0047] Exemplarily, the light guide plate 1 and the light guide column 2 are integrally formed, which further simplifies the assembly process and reduces assembly time.

[0048] Furthermore, the light guide plate 1, the light guide column 2, the light transmission part 4 and the light homogenizing part 5 are all integrally formed, specifically by transparent polycarbonate material. In this embodiment, the light guide plate 1, the light guide column 2, the light transmission part 4 and the light homogenizing part 5 are injection molded or hot-pressed by polycarbonate material with a grade of PC945A.

[0049] Exemplarily, the light shielding layer 3 is an opaque black paint layer with good light absorbing properties. Of course, in other embodiments of the present invention, the light shielding layer 3 can also be set as a paint layer of other colors such as gray, brown, etc., which can also hinder or block light from passing through.

[0050] Exemplarily, the light-shielding layer 3 is formed by spraying paint. Before spraying the paint, a protective tape is attached to the outside of the light-transmitting portion 4 and the light-evening portion 5. After spraying, the protective tape is torn off to maintain the transparency of the light-transmitting portion 4 and the light-evening portion 5 and ensure the light-guiding effect.

[0051] For example, Figure 1 and Figure 2 As shown, the display assembly also includes a power supply socket 40, which is installed on the side of the light board 20 away from the light guide plate 1. The light board 20 is provided with a PCB, which is electrically connected to the light source and the power supply socket 40.

[0052] For example, Figure 1 and Figure 2 As shown, the buffer plate 50 is set as a soft plate structure, which is made of waterproof PE foam, and the buffer plate 50 is used to absorb the impact between the light guide structure 10, the light board 20 and the shell. The buffer plate 50 is provided with a plurality of clearance holes 501 corresponding to the light guide columns 2, and the light-transmitting parts 4 are passed through the clearance holes 501 in a one-to-one correspondence.

[0053] For example, Figure 1 and Figure 2 As shown, two symmetrically arranged connecting sleeves 6 are integrally formed on the light guide plate 1, and a shading layer 3 is provided on the inner and outer sides of the connecting sleeve 6. Two first mounting holes 202 are provided on the lamp board 20, and two second mounting holes 502 are provided on the buffer plate 50. The light guide structure 10, the lamp board 20 and the buffer plate 50 are locked to the outer shell by fastening screws that pass through the first mounting holes 202, the connecting sleeve 6 and the second mounting holes 502 in sequence.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
