Description

Technical Field

[0001] This utility model relates to the field of information indicator light technology, and in particular to a scratch-resistant and UV-resistant energy storage power information indicator light strip assembly. Background Technology

[0002] Residential energy storage is an energy storage management system applied in home environments. It is typically equipped with an information light bar with a power display function. This information light bar can display the current energy storage status through multiple indicator lights or a variable digital display screen. This design allows users to clearly understand the energy reserve status, thereby better managing energy use and ensuring that there is a sufficient power supply when needed.

[0003] The power display of existing energy storage devices generally uses outdated designs, such as old-fashioned LED digital tubes or monochrome LCD screens that can only display simple numbers or symbols, and have problems with no backlight or insufficient backlight, making them almost unreadable at night or in dim environments; at the same time, due to unreasonable structural design, there are problems with poor display uniformity and dark areas.

[0004] On the other hand, the installation of the power information indicator module is cumbersome, and the panel surface is easily scratched and damaged during use, resulting in high maintenance costs. Furthermore, traditional displays are not resistant to ultraviolet rays; prolonged exposure to outdoor sunlight can cause fading, aging, and decreased contrast, gradually making the displayed content fade until it becomes unreadable. These problems collectively lead to an increased failure rate when the device operates outdoors for extended periods, significantly reducing user experience and device reliability, while also driving up maintenance costs, making it difficult to meet the needs of outdoor use. Utility Model Content

[0005] The purpose of this invention is to provide a scratch-resistant and UV-resistant energy storage power information indicator light strip assembly to overcome the shortcomings of existing technologies.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A scratch-resistant and UV-resistant energy storage power information indicator strip assembly includes a PCB board, a light guide fixing layer, and a tempered glass panel that are sequentially bonded together, wherein the PCB board, the light guide fixing layer, and the tempered glass panel are connected by an anti-UV layer;

[0008] The PCB board has multiple light sources arranged at equal intervals on one side, and is mounted on the equipment on the other side with adhesive backing.

[0009] The light guide fixing layer is located on the side of the PCB board where the light source is mounted, and multiple independent light areas are provided for the multiple light sources, separated by intervals.

[0010] The tempered glass panel is located on the side of the light guide fixing layer away from the PCB board. The light from the light source is transmitted through the tempered glass panel to display the power level and power-on status.

[0011] In some embodiments, the light guide fixing layer includes a light-concentrating strip and a diffusion film;

[0012] The light-concentrating strip is disposed on the PCB board. The light-concentrating strip has light-transmitting holes and power holes. Multiple light-transmitting holes are separated by the interval along the long axis of the light-concentrating strip to form multiple independent lamp areas. Each light-transmitting hole corresponds to at least one light source.

[0013] The diffusion film is embedded in the light-transmitting hole, and when in use, the light from the light source is emitted through the diffusion film.

[0014] In some embodiments, the light-transmitting hole has an enlarged stepped surface on the side wall away from the PCB board, and the diffusion film is embedded on the stepped surface and flush with the same side of the light-concentrating strip.

[0015] In some embodiments, the thickness of the gap between two adjacent light-transmitting holes gradually increases from the side away from the light source to the side facing the light source, and the cross-section of the gap is trapezoidal.

[0016] In some embodiments, the tempered glass panel is coated with a black base color on the side near the light guide fixing layer, and a light-transmitting area is reserved corresponding to the plurality of light-transmitting holes;

[0017] The tempered glass panel is also provided with an indicator area corresponding to the power port.

[0018] In some embodiments, the UV-resistant layer includes a first adhesive layer bonded between the tempered glass panel and the light-concentrating strip, and a second adhesive layer bonded between the light-concentrating strip and the PCB board.

[0019] In some embodiments, the adhesive backing has through holes for leading out the ribbon cables of the PCB board.

[0020] The beneficial effects of this utility model are:

[0021] The scratch-resistant and UV-resistant energy storage power information indicator strip assembly provided by this utility model forms an optical and physical isolation structure through the light-transmitting holes and intervals on the focusing strip, which isolates each independent light area from each other and effectively suppresses light crosstalk.

[0022] The design of gradually increasing spacing from the side away from the light source to the side closer to the light source helps to expand the light guiding range, improve light uniformity, and eliminate dark areas in the light strip.

[0023] The black tempered glass panel is bonded to an anti-UV layer, which significantly improves its scratch resistance and UV aging resistance, meeting the requirements for use in outdoor environments with long-term exposure to sunlight and rain and dust. Combined with an industrial-grade adhesive backing and a wiring installation mechanism with through holes, it enables rapid assembly and stable bonding in both indoor and outdoor environments, and facilitates cable routing and subsequent maintenance.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figures 1-6 As shown, this embodiment of the utility model provides a scratch-resistant and UV-resistant energy storage power information indicator light strip assembly, including a PCB board 1, a light guide fixing layer, and a tempered glass panel 5, which are sequentially bonded and fixed together by an anti-UV layer. Multiple light sources 2 are installed at equal intervals on one side of the PCB board 1, and an adhesive backing 8 is provided on the other side. The adhesive backing 8 uses VHB high-performance double-sided adhesive. The ribbon cables 9 of the PCB board 1 are led out from the wire holes 81 of the adhesive backing 8. The adhesive backing 8 is used to bond and fix the PCB board 1 to the corresponding device. In this embodiment, the device can be a household energy storage cabinet placed indoors or outdoors. The light guide fixing layer is located on the side of the PCB board 1 where the light sources 2 are installed. The light guide fixing layer has independent light areas separated by intervals 32 corresponding to the multiple light sources 2 to achieve light guidance. The tempered glass panel 5 is located on the side of the light guide fixing layer away from the PCB board 1. The light from the light sources 2 is guided and diffused before passing through the tempered glass panel 5 to display the power level and power-on status.

[0037] In this embodiment, an anti-UV layer is used to achieve reliable bonding between the tempered glass panel 5 and the light guide fixing layer, thereby improving weather resistance and resistance to ultraviolet aging. The tempered glass panel 5 provides a scratch-resistant outer surface and is easy to form a light-shielding background. Combined with independent light areas, it improves display contrast and uniformity, making it suitable for both outdoor and indoor scenarios.

[0038] It should be specifically noted that, in order to achieve direct light emission of the light source 2 on the PCB board 1 through independent lamp areas and prevent light crosstalk, the light guide fixing layer provided in this embodiment includes a focusing strip 3 and a diffusion film 4, with the diffusion film 4 embedded in the focusing strip 3. The focusing strip 3 is located on the PCB board 1 and has multiple light-transmitting holes 31 along its long axis. The multiple light-transmitting holes 31 are spaced apart by a gap 32 to form independent lamp areas, with at least one light source 2 corresponding to each independent lamp area. In addition, a power hole 34 for indicating the power-on status is also provided at the end of the focusing strip 3 along its long axis. It should be noted that the focusing strip 3 is made of opaque material. For example, the focusing strip 3 can be made of black PE material, thereby physically isolating the multiple light sources 2 in one light-transmitting hole 31 from the multiple light sources 2 in adjacent light-transmitting holes 31. The light from the light source 2 can only be emitted through the light-transmitting hole 31, which can effectively prevent light crosstalk and eliminate light interference. In this embodiment, the light source 2 is an LED lamp bead, and every seven LED lamp beads form a group corresponding to one light-transmitting hole 31. The light-transmitting hole 31 is an elongated hole, such as... Figure 3 As shown, the spotlight strip 3 has four elongated holes, corresponding to twenty-eight LED beads. The power hole 34 is a round hole, corresponding to one LED bead, used to individually display the power status. In use, multiple LED beads in each elongated light-transmitting hole 31 light up and turn off simultaneously. The four elongated light-transmitting holes 31 each correspond to 25% of the battery level: when all LED beads are lit, it indicates a full charge; when any LED bead in any light-transmitting hole 31 is off, it indicates that the total battery level has decreased by 25%, thus achieving battery level indication.

[0039] Furthermore, in this embodiment, the thickness of the gap 32 between two adjacent light-transmitting holes 31 gradually increases from the side furthest from the light source 2 to the side closest to the light source 2, such as... Figure 4 As shown, the two sidewalls of the spacer 32 are sloped, meaning that the two sidewalls slope downwards and away from each other from top to bottom, thus forming the spacer 32 with a trapezoidal cross-section, as shown. Figure 6 As shown, the end of the gap 32 facing the light source 2 has a large thickness, which effectively isolates the two adjacent light sources 2, prevents light crosstalk, and facilitates the emission of light. At the same time, the trapezoidal cross section of the gap 32 makes the cross section of the light-transmitting hole 31 gradually increase in the emission direction, which helps to expand the light guiding range, achieve uniform light distribution, and make the light emission effect of the light source 2 uniform and without dark areas.

[0040] As mentioned above, the diffuser film 4 is set to correspond to the light-transmitting holes 31 on the light-concentrating strip 3. Each light-transmitting hole 31 is embedded with a diffuser film 4. The diffuser film 4 is made of PC material (polycarbonate) and has a good light uniformity effect. In use, the light from the light source 2 is physically isolated by the independent lamp area in the light-concentrating strip 3 and reaches the diffuser film 4. The diffuser film 4 is used to convert the emitted light from the point light source into a uniform surface light source, forming uniform emitted light. By combining the diffuser film 4 with the light-concentrating strip 3, the light source 2 is diffused a second time to improve the light uniformity effect and reduce ghosting and flooding, ensuring display uniformity.

[0041] Considering that the diffusion film 4 forms a stable installation within the light-transmitting hole 31 of the light-concentrating strip 3, and facilitates the neat attachment of the light-guiding fixing layer to the tempered glass panel 5 later, such as Figure 5 and Figure 6 As shown, a stepped surface 33 is provided at the end of the light-transmitting hole 31 away from the light source 2 to form an installation groove. The thickness of the diffusion film 4 is equal to the depth of the installation groove. The diffusion film 4 is installed on the stepped surface 33 and is glued and fixed to the contact part of the stepped surface 33. After installation, the diffusion film 4 is flush with the surface of the light-concentrating strip 3. The diffusion film 4 is made of transparent PC material. The assembly method of embedding it into the light-transmitting hole 31 can ensure that the surface of the light-concentrating strip 3 is flat and without protrusions, which is conducive to subsequent sealing and bonding, and improves the assembly quality and appearance consistency.

[0042] like Figure 2 As shown, the UV-resistant layer includes a first adhesive layer 6 and a second adhesive layer 7. The tempered glass panel 5 is bonded to the light-concentrating strip 3 through the first adhesive layer 6, and the light-concentrating strip 3 is bonded to the PCB board 1 through the second adhesive layer 7. The first adhesive layer 6 and the second adhesive layer 7 are respectively provided with avoidance holes to avoid the light source 2, the light-transmitting hole 31, or the light-transmitting area 51. The first adhesive layer 6 is preferably a UV-resistant black adhesive. The UV-resistant layer maintains the bonding strength and resists ultraviolet aging during long-term outdoor use, avoiding the problems of delamination and fading of the tempered glass panel 5. The second adhesive layer 7 is a regular black adhesive. The use of different materials for layered bonding is beneficial for sealing, dustproofing and waterproofing, and can reduce costs while ensuring product quality.

[0043] In this embodiment, to ensure that the information indication is clear and readable and does not obstruct the light path, the tempered glass panel 5 is coated with a black background on the side near the light guide fixing layer, and the corresponding positions of the multiple light-transmitting holes 31 are not coated to reserve the light-transmitting area 51. The light-transmitting area 51 is a long strip structure, which is set to correspond to the four long strip light-transmitting holes 31 on the light-focusing strip 3. The black background can improve the display contrast and suppress stray light, so that the light from the light source 2 can only be emitted through the light-transmitting area 51. The light-transmitting area 51 is set directly opposite the multiple light-transmitting holes 31. Along the long axis of the light-focusing strip 3, the length of the light-transmitting area 51 is not less than the sum of the lengths of the multiple light-transmitting holes 31 to ensure that the light source 2 is not obstructed. Typically, the width of the short axis of the light-transmitting area 51 is not greater than the width of the light-transmitting hole 31, and the two ends of the long axis of the light-transmitting area 51 are aligned with the two ends of the light-transmitting hole 31. Similarly, the tempered glass panel 5 also has an indicator area 52 corresponding to the power hole 34. The indicator area 52 is circular and corresponds to the power hole 34 on the light-focusing strip 3. It is used to indicate the power-on status. That is, the LED beads in the indicator area 52 are lit up to indicate the power-on status, otherwise it is the power-off status.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
