[0035] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0036] Please also read Figures 1 to 6 , the light output structure assembly provided by the utility model is now described. The light output structure assembly includes a cover plate 1, a light guide plate 2 and a light source plate 3; the cover plate 1 has a light output opening 101; the light guide plate 2 is attached to the rear side of the cover plate 1, and the front side of the light guide plate 2 protrudes to form a light guide column 4, and the light guide column 4 is inserted into the light output opening 101; the light source plate 3 is arranged on the rear side of the light guide plate 2, and the light source 310 on the front side of the light source plate 3 is arranged corresponding to the light guide column 4; the light output structure assembly also includes a snap-on component 5, which is snap-on with the edge of the light source plate 3 to limit the displacement of the light source plate 3 in the front-back direction.

[0037] In this embodiment, the light source 310 on the front side of the light source plate 3 is a point light source 310, and its specific implementation includes but is not limited to an LED point light source 310, a xenon point light source 310, etc. In addition, the number and arrangement of the light sources 310 are affected by the light guide column 4, and generally an arrangement is adopted that follows the cross-section of the light guide column 4; for example, if the cross-section of the light guide column 4 is a strip, then the multiple light sources 310 are distributed along the long axis of the cross-section; if the cross-section of the light guide column 4 is a rectangle, then the multiple light sources 310 are distributed in a rectangular array corresponding to the cross-section. The remaining embodiments are not listed here one by one.

[0038] In this embodiment, the light guide plate 2 and the light guide column 4 can even out and diffuse the light, thereby making the light emitted by the light guide column 4 more uniform and soft. The light guide column 4 and the light guide plate 2 are integrally formed and can be made of milky white PC material, which has good light transmittance, soft light output effect, and beautiful appearance.

[0039] In the present embodiment, the light guide column 4 is arranged in a conformal relationship with the light outlet opening 101, and the gap between the outer peripheral surface of the light guide column 4 and the inner wall surface of the light outlet opening 101 does not exceed 0.5 mm. By reasonably setting the size of the light outlet opening 101, it is ensured that the light outlet surface passing through the light outlet structure assembly is the front side surface of the light guide column 4, thereby better controlling the light outlet effect, and the light outlet contour shape is roughly the same as the contour of the light guide column 4.

[0040] In this embodiment, the front plate surface of the light guide plate 2 is preferably set as a plane, so that the rear plate surface of the cover plate 1 corresponds to it, which is convenient for assembly. The cover plate 1 of this embodiment can be the top plate or side plate of the device, and the light output structure assembly of this embodiment can be set in any area that needs to provide status prompts through light; wherein, the cover plate 1 is an opaque plate or a plate with low light transmittance to avoid affecting the light output effect of the light guide column 4.

[0041] In this embodiment, in order to fully improve the reliability of lighting, the front side of the light guide column 4 is flush with the front surface of the cover plate 1 , or the front side of the light guide column 4 protrudes forward from the front surface of the cover plate 1 .

[0042] Compared with the prior art, the light output structure assembly provided in the present embodiment has a cover plate 1 which can be set as a plate at any position on the equipment where function prompts are required. During installation, the light guide plate 2 is first installed on the cover plate 1, and then the light source plate 3 is clamped by the clamping component 5 on the rear side of the light guide plate 2. There is no need to set a connecting structure for installing the light source plate 3 on the cover plate 1. By assembling and integrating the light source plate 3 with the light guide plate 2, the number of connection points on the cover plate 1 is reduced, the problem of too many installation points affecting the appearance of the equipment is avoided, and the difficulty of loading and unloading is reduced. In addition, since the light source plate 3 and the light guide plate 2 are assembled by clamping, the thread locking process is reduced while meeting the assembly requirements, thereby reducing the difficulty of assembly, improving the efficiency of assembly, and reducing the difficulty of loading and unloading.

[0043] In some specific embodiments, see Figures 2 to 6 In order to make the front light of the light guide column 4 more uniform and to make more full use of the light emitted by the light source 310, a light output installation area corresponding to the front and rear of the light source board 3 is formed on the rear side of the light guide plate 2, and the light guide column 4 is located at the center of the light output installation area. Based on this, in order to achieve the locking of the positions of the light guide plate 2 and the light source board 3 and avoid the problem of the light source board 3 shaking, a second connecting column 6 is provided on the rear side of the light guide plate 2, and the second connecting column 6 is located in the light output installation area. On the rear plate surface of the light guide plate 2, the second connecting column 6 and the light guide column 4 are staggered; a second light guide connecting hole is provided in the second connecting column 6, and a light source 310 installation hole corresponding to the second light guide connecting hole is provided on the light source board 3, and the light source board 3 and the second connecting column 6 are fixedly connected by a second fastener 7 that penetrates the light source 310 installation hole and the second light guide connecting hole. Among them, the implementation method of the second fastener 7 includes but is not limited to threaded fasteners such as bolts and screws.

[0044] During specific implementation, since the snap-fit ​​assembly 5 has already achieved basic positioning of the light source board 3, there is no need to set too many threaded fastening points. This embodiment exemplarily shows an embodiment in which a light source 310 mounting hole is set in the middle of the light source board 3 at a position offset from the light guide column 4, thereby minimizing the number of threaded fasteners used while ensuring assembly reliability.

[0045] In some embodiments, the above-mentioned clamping assembly 5 can be used as follows Figures 2 to 6In the structure shown, the snap-on assembly 5 includes a plurality of snap hooks 510 and a plurality of positioning brackets 520, and the snap hooks 510 and the positioning brackets 520 are alternately arranged along the circumference of the light-emitting installation area; the rear portion of the snap hook 510 forms a hook-connection limiting surface in contact with the rear plate surface of the light source board 3, and the positioning bracket 520 has a support limiting surface 5202 in contact with the front plate surface of the light source board 3, and the hook-connection limiting surface cooperates with the support limiting surface 5202 to clamp and limit the light source board 3 in the front-to-back direction. This embodiment avoids the overlap of the snap hooks 510 and the positioning brackets 520 by alternately arranging the snap hooks 510 and the positioning brackets 520, compresses the space occupied by the snap-on assembly 5 in the direction perpendicular to the front-to-back direction, and at the same time, makes the force on the light source board 3 uniform, thereby avoiding cracking of the light source board 3.

[0046] Based on the above embodiments, see Figure 5 and Figure 6 The positioning bracket 520 also has a circumferential limiting surface 5201 that contacts and limits the outer circumference of the light source board 3 to limit the displacement of the light source board 3 in a direction perpendicular to the front-rear direction. This embodiment adds a circumferential limiting function to further improve the reliability of the positioning of the light source board 3 and facilitate the installation of the second fastener 7.

[0047] In some embodiments, the positioning bracket 520 may be used as follows: Figures 2 to 6 In the structure shown, the positioning bracket 520 includes a circumferential limit plate 521 and a support plate 522. The circumferential limit plate 521 is vertically connected to the rear plate surface of the light guide plate 2 and is a strip-shaped plate extending along the circumferential contour of the light output installation area. The side surface of the circumferential limit plate 521 facing the light output installation area forms a circumferential limit surface 5201; the support plate 522 is connected between the light guide plate 2 and the circumferential limit plate 521, and is respectively perpendicular to the light guide plate 2 and the circumferential limit plate 521, and the rear edge of the support plate 522 forms a support limit surface 5202. In specific implementation, a plurality of support plates 522 are provided along the extension direction of the corresponding circumferential limit plate 521 to improve the reliability of the support and the uniformity of the force on the light source board 3. The positioning bracket 520 of this embodiment has a simple structure. The circumferential limit plate 521 and the support plate 522 can not only achieve the corresponding support and limit effect, but also interact with each other to improve the overall structural strength of the positioning bracket 520 and the reliability of the assembly of the light source board 3.

[0048] Based on the specific structure of the positioning bracket 520, see Figures 2 to 6Optionally, the positioning bracket 520 also includes an edge limiting rib 523, which is connected between the light guide plate 2 and the circumferential limiting plate 521, and is respectively perpendicular to the light guide plate 2 and the circumferential limiting plate 521. The edge of the light source board 3 is provided with an edge limiting groove 302, and the rear end of the edge limiting rib 523 is inserted into the edge limiting groove 302. In this embodiment, the edge limiting rib 523 is connected with the edge limiting groove 302 to further enhance the limiting effect along the circumferential contour line of the light source board 3, and it is also convenient for the light source board 3 to be aligned with the light output installation area. It should be noted that the edge limiting rib 523 is provided on some positioning brackets 520, and the edge limiting rib 523 is not provided on the other positioning brackets 520, so as to avoid opening too many edge limiting grooves 302 on the light source board 3.

[0049] In some embodiments, see Figures 2 to 6 In order to realize the connection between the light guide plate 2 and the cover plate 1, a light guide installation area is formed on the periphery of the light output installation area, and a plurality of first connection columns 8 are provided in the light guide installation area, and the plurality of first connection columns 8 are distributed along the circumference of the light output installation area; a first light guide connection hole is provided in the first connection column 8, and a cover plate 1 connection hole corresponding to the first light guide connection hole is provided on the cover plate 1, and the cover plate 1 and the light guide plate 2 are fixedly connected by a first fastener 9 that penetrates the first light guide connection hole and the cover plate 1 connection hole. Among them, the implementation method of the first fastener 9 includes but is not limited to threaded fasteners such as bolts and screws. In specific implementation, in order to make the front panel surface of the light guide plate 2 as close to the cover plate 1 as possible, and at the same time, it is also necessary to meet the fastening requirements, the first light guide connection hole is passed through the first connection column 8 from front to back, and the first fastener 9 penetrates into the first light guide connection hole from the front side of the cover plate 1, and is connected and locked with the first light guide connection hole.

[0050] In some embodiments, see Figures 2 to 6 A first reinforcing rib plate 10 is provided between two adjacent first connecting columns 8, and a second reinforcing rib plate 11 is provided between the first reinforcing rib plate 10 and the hook 510. The first reinforcing rib plate 10 forms a support between two adjacent first connecting columns 8, and this support surrounds the light output installation area, which plays a positive role in improving the overall structural strength of the light guide plate 2. The second reinforcing rib plate 11 forms a support between the first reinforcing rib plate 10 and the hook 510 to prevent the hook 510 from breaking.

[0051] Based on the above embodiments, see Figures 2 to 6A third reinforcing rib 12 extending in a direction away from the first reinforcing rib 10 is also provided on the outer periphery of the first connecting column 8. The third reinforcing rib 12 is provided between the first connecting column 8 and the light guide plate 2 and extends to the edge of the light guide plate 2. The provision of the third reinforcing rib 12 increases the circumferential reinforcement support points of the first connecting column 8, realizes multi-directional reinforcement, effectively improves the torsional and bending resistance between the first connecting column 8 and the light guide plate 2, improves the structural stability of the first connecting column 8, and avoids the problem of deformation and breakage of the first connecting column 8 after assembly or long-term use.

[0052] During specific implementation, the setting position of the first connecting column 8 corresponds one-to-one to each corner of the first light guide plate 2, the setting of the first reinforcing rib plate 10 is roughly the same as the edge contour shape of the light guide plate 2, and the same first connecting column 8 corresponds to two first reinforcing rib plates 10 and two third reinforcing rib plates 12. The extension path of the third reinforcing rib plate 12 is parallel to the extension path of the corresponding first reinforcing rib plate 10, forming a cross-type rib plate configuration, which simplifies the number of reinforcing rib plates set and ensures the reinforcement effect.

[0053] In some embodiments, see Figures 2 to 6 In order to achieve a lightweight design, a plurality of weight-reducing grooves 14 are further provided in the light guide installation area. The plurality of weight-reducing grooves 14 are distributed along the circumference of the light output installation area, and each weight-reducing groove 14 is located on the side of the first reinforcing rib plate 10 away from the light output installation area. More specifically, the edge of the weight-reducing groove 14 extends to the board surface of the first reinforcing rib plate 10 away from the light output installation area.

[0054] In some specific configurations of the light guide column 4, see Figures 1 to 6 The light guide column 4 is a column with an oblong cross section, so that the light guide column 4 has a narrow and long light output area. Under the premise of ensuring the lighting brightness, it can be suitable for the setting and lighting needs of the narrow area inside the equipment.

[0055] In other specific configurations of the light guide column 4, not shown in the figures, the cross-section of the light guide column 4 may be circular, triangular, square, etc., which is not limited here.

[0056] In some embodiments, see Figures 2 to 6 , a light guide groove 15 is provided on the rear panel of the light guide plate 2. The light guide groove 15 is located within the light output installation area and is arranged corresponding to the light source 310 on the light source plate 3. The depth of the light guide groove 15 is set according to the light output requirement. The front wall surface of the light guide groove 15 is the light incident surface. Properly setting the depth of the light guide groove 15 can optimize the distance from the light source 310 to the light incident surface of the light guide plate 2, thereby adjusting the light output effect. More specifically, the light guide groove 15 is arranged in a shape similar to the light guide column 4. For example, the light guide column 4 with an oblong cross-section is adapted to the rectangular light guide groove 15 (such as Figure 3As shown in the figure), the light guide column 4 with a circular cross section is adapted to the circular light guide groove 15 (not shown in the figure).

[0057] In some embodiments, see Figure 2 and Figure 3 In order to ensure the sealing around the light outlet opening 101 , a sealing gasket 16 is provided between the light guide plate 2 and the cover plate 1 , and the sealing gasket 16 is arranged around the light guide column 4 .

[0058] Based on the above embodiments, see Figure 3 A positioning ring groove 17 is provided on the front side of the light guide plate 2, and the positioning ring groove 17 is arranged around the light guide column 4. The sealing gasket 16 is placed in the positioning ring groove 17 to limit the displacement of the sealing gasket 16 in a direction perpendicular to the front-back direction. Specifically, in order to reduce the impact on the light output effect, the positioning ring groove 17 is located at the periphery of the light guide groove 15 to avoid overlapping with the light guide groove 15.

[0059] More specifically, the positioning ring groove 17 and the light guiding groove 15 are arranged in a conformal manner, and the specific arrangement manners thereof are not listed one by one here.

[0060] Based on the same inventive concept, an embodiment of the present application also provides an energy storage device, including the above-mentioned light output structure assembly.

[0061] Compared with the prior art, the energy storage device provided in this embodiment adopts the above-mentioned light output structure assembly, so the appearance of the device is more beautiful and the overall assembly efficiency is improved.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
