Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] Please see Figures 1-3 ,in, Figure 1 This is a schematic diagram of the structure of the energy storage power conversion device 100 according to an embodiment of this application. Figure 2 This is a schematic diagram of the structure of the traffic light assembly 10 according to an embodiment of this application. Figure 3 This is a cross-sectional schematic diagram of the signal light assembly 10 and the panel 20 according to an embodiment of this application.

[0032] The signal light assembly 10 provided in this embodiment is installed on the panel 20 of the energy storage power conversion device 100. The signal light assembly 10 includes a connecting plate 11, a lamp plate 12, a sleeve 13, a light guide post 14, and a sealing member 15. The connecting plate 11 is disposed on the panel 20. The lamp plate 12 is connected to the side of the connecting plate 11 away from the panel 20. The sleeve 13 is disposed on the panel 20 and extends from the panel 20 toward the connecting plate 11. The light guide post 14 passes through the sleeve 13 and abuts against the panel 20 and the connecting plate 11. The sealing member 15 is installed inside the sleeve 13 and is located between the bottom of the light guide post 14 and the top of the panel 20.

[0033] Specifically, the connecting plate 11 can be made of metal, and its shape can be adapted to the panel 20. The connecting plate 11 can be fixed to the panel 20 by welding, bolting, or snap-fitting. The connecting plate 11 serves to connect the lamp panel 12 and the panel 20, providing an installation position for the lamp panel 12. It also serves to hold the light guide column 14 to press the sealing element 15, achieving a good sealing effect.

[0034] The lamp board 12 may include a PCB board, possessing good electrical performance and stability. The circuit layout of the lamp board 12 employs a multi-layer wiring method, effectively reducing interference between lines and improving signal transmission stability. The lamp board 12 emits light, which is directed to the light guide post 14. The light guide post 14 guides the light from the lamp board 12 to the outer side of the panel 20.

[0035] The light guide post 14 can be made of acrylic, also known as polymethyl methacrylate (PMMA). Acrylic has good light transmittance and mechanical strength, and is easy to process and shape. The light guide post 14 is cylindrical in shape, and its diameter matches the inner diameter of the sleeve 13. The surface roughness of the light guide post 14 is small to reduce light scattering on the surface and improve light transmission efficiency.

[0036] In addition, related technologies involve creating a light guide column with a sealing function through mold making, cutting a sealing groove on the light guide column, inserting a sealing strip into the sealing groove, and then tightening it with screws to achieve a seal. In this embodiment, the light guide column 14 can be obtained by cutting a standard light-transmitting rod available on the market, without the need for mold making. Therefore, compared with the mold-making manufacturing solution for the light guide column, the signal light assembly 10 in this embodiment greatly reduces the cost investment in the early stage of production.

[0037] The sleeve 13 can be made of metal (such as stainless steel or aluminum alloy), plastic, or composite materials. The sleeve 13 has good strength to provide a certain degree of protection for the light guide post 14. The inner surface of the sleeve 13 is polished to reduce the roughness of the inner surface of the sleeve 13, thereby reducing the obstruction of light and making the light transmission smoother.

[0038] The seal 15 can be made of silicone rubber. The seal 15 has good elasticity and sealing performance, and can generate sufficient sealing pressure when compressed. The seal 15 is installed by being pre-placed inside the sleeve 13 and in contact with the panel 20. When the light guide post 14 is inserted into the sleeve 13, the seal 15 is compressed under the resistance of the connecting plate 11 and the light guide post 14, thereby achieving a tight seal between the light guide post 14 and the panel 20, preventing the entry of moisture, dust, and other foreign matter.

[0039] By setting a sealing element 15 between the bottom of the light guide column 14 and the top of the panel 20, and utilizing the cooperation of the light guide column 14, connecting plate 11, and panel 20 to tightly press the sealing element 15, a good sealing effect is achieved, meeting IP protection requirements, preventing external dust, moisture, etc. from entering the interior, improving the overall reliability and stability of the signal light assembly 10, and facilitating installation. It can achieve an IP66 protection rating.

[0040] In some embodiments, the signal light assembly 10 may further include a heat sink mounted on the back of the light panel 12, that is, the side of the light panel 12 facing away from the connecting plate 11. The heat sink is used to dissipate heat from the light panel 12, ensuring that the light panel 12 will not be affected by overheating during long-term operation.

[0041] In some embodiments, there is a gap between the outer wall of the light guide post 14 and the inner wall of the sleeve 13. The gap makes it easier for the light guide post 14 to be inserted into the sleeve 13 during installation, which facilitates installation and improves assembly efficiency.

[0042] When the energy storage power conversion device 100 is affected by factors such as vibration or temperature changes during operation, the light guide column 14 and the sleeve 13 may undergo slight displacement or deformation. The existence of the gap can avoid stress concentration caused by excessive compression between the light guide column 14 and the sleeve 13, thereby reducing the risk of damage to the light guide column 14 due to excessive force.

[0043] In some embodiments, the signal light assembly 10 includes a light source 16 disposed from the light plate 12 toward the light guide column 14, and the connecting plate 11 is provided with a through hole 111 coaxial with the sleeve 13, the through hole 111 being used for the light from the light source 16 to pass through.

[0044] Positioning the light source 16 on the lamp plate 12 towards the light guide column 14 ensures that the light can be smoothly transmitted through the light guide column 14, meeting the illumination indication requirements of the signal light. A through hole 111, coaxial with the sleeve 13, is provided on the connecting plate 11 to accommodate the light source 16, providing precise positioning for the light source 16, ensuring a stable light propagation path, and reducing light loss and deflection.

[0045] In use, the light emitted by the light source 16 passes through the through-hole 111 and enters the light guide post 14 from the end away from the panel 20, and exits from the end of the light guide post 14 closer to the panel 20. The light source 16 can be an LED light or an OLED light, etc., and is not limited thereto. The through-hole 111 can be circular in shape, with a smooth inner wall to reduce reflection interference to the light source 16.

[0046] The number of light sources 16 can be one or more. Multiple light sources 16 can be equidistantly spaced on the lamp panel 12, with each light guide post 14 corresponding to a light source 16. It is understood that the number of sleeves 13 is the same as the number of light guide posts 14, with each sleeve 13 corresponding to a light guide post 14. The number of through holes 111 is the same as the number of light sources 16, with each through hole 111 corresponding to a light source 16.

[0047] In some embodiments, the top of the light guide post 14 protrudes beyond the top of the sleeve 13. This protruding top of the light guide post 14 reduces light obstruction by the sleeve 13, allowing more light to escape from the top of the light guide post 14, thus improving the brightness and visibility of the signal light assembly 10. Furthermore, the exit angle and propagation direction of the light can be changed as needed, allowing the light to be scattered into the surrounding environment at a more suitable angle, expanding the visible range of the signal light assembly 10.

[0048] Please see Figure 4 , Figure 4 This is a cross-sectional schematic diagram of the light guide post 14 according to an embodiment of this application. In some embodiments, a mounting groove 141 is formed on the bottom surface of the light guide post 14, which is used to install the sealing element 15. Specifically, the mounting groove 141 is formed on the bottom surface of the light guide post 14 along the circumferential direction, and the sealing ring is embedded in the mounting groove 141 and tightly sealed against the inner end face of the smaller stepped hole of the mounting hole. The mounting groove 141 provides precise positioning for the sealing element 15, so that the sealing element 15 can be accurately installed in the predetermined position, avoiding offset or misalignment during the installation process, improving the accuracy of installation, and facilitating the rapid assembly of the signal light assembly 10.

[0049] The mounting groove 141 can better secure the seal 15, preventing it from shifting, deforming, or falling off during use. The seal 15 can be an O-ring, a square ring, a gasket, or other suitable sealing material. The mounting groove 141 can be designed to accommodate different sizes and shapes of the seal 15.

[0050] In addition, the mounting groove 141 can provide some protection for the seal 15, reduce the risk of the seal 15 being subjected to external impact, friction or chemical corrosion, extend the service life of the seal 15, and thus ensure the long-term sealing performance of the signal light assembly 10.

[0051] In some embodiments, the light guide post 14 includes a body and a boss connected to the body. The boss is connected to the panel 20, and the diameter of the boss is smaller than the diameter of the body. The seal 15 is fitted onto the boss. The edge of the boss away from the body may be chamfered to facilitate the fitting of the seal 15 and to prevent scratching of the seal 15 during installation.

[0052] In some embodiments, a first mounting hole 121 is formed on the lamp panel 12, and the signal light assembly 10 further includes a first fastener 17, which passes through the first mounting hole 121 and is connected to the connecting plate 11.

[0053] The first fastener 17 is used to connect the lamp board 12 and the connecting plate 11 to avoid external forces caused by vibration during the operation of the energy storage power conversion device 100, maintain the stability of the relative position of the lamp board 12 and the connecting plate 11, prevent the lamp board 12 from shifting, and thus ensure that components such as the light source 16 and the light guide column 14 are always in a precise alignment state, so that the light transmission is not disturbed.

[0054] The number of first mounting holes 121 can be one or more, with multiple first mounting holes 121 spaced apart on the lamp panel 12, and each first fastener 17 corresponding to a first mounting hole 121. For example, there can be two first fasteners 17 and two first mounting holes 121, with the two first mounting holes 121 located at both ends of the lamp panel 12, and the two first fasteners 17 corresponding to the two first mounting holes 121 respectively.

[0055] In some embodiments, a second mounting hole 112 is formed on the connecting plate 11, and the signal light assembly 10 further includes a second fastener 18, which passes through the second mounting hole 112 and is connected to the panel 20. The second fastener 18 is used to connect the connecting plate 11 and the panel 20.

[0056] The first fastener 17 and the second fastener 18 can be screws, bolts, rivets, etc., without restriction. The appropriate type of fastener should be selected according to actual needs. Screw-on or bolted connections facilitate disassembly and repair during maintenance and repair.

[0057] In some embodiments, in order to prevent the first fastener 17 and the second fastener 18 from loosening during use, anti-loosening measures such as locking washers or special locking screws may be used.

[0058] When installing the signal light assembly 10, first place the sleeve 13 at a preset position on the panel 20 of the energy storage power conversion device 100. The sleeve 13 is connected to the panel 20 by means of embedding, adhesive, or threaded connection. Then, place the sealing member 15 flat inside the sleeve 13, and then insert the light guide post 14 into the sleeve 13. Next, use the second fastener 18 to pass through the second mounting hole 112 of the connecting plate 11 and tighten it into the threaded hole on the panel 20. When tightening the second fastener 18, the connecting plate 11 will move towards the panel 20, thereby making the sealing member 15 fully pressed against the panel 20. The sealing member 15 is tightly fitted between the bottom of the light guide post 14 and the top of the panel 20 to achieve a seal. Align the light source 16 on the light plate 12 with the through hole 111 on the connecting plate 11, and then pass the first fastener 17 through the first mounting hole 121 of the light plate 12 and tighten it into the threaded hole on the connecting plate 11. During the tightening of the first fastener 17, since the connecting plate 11 is already stable, the seal 15 can maintain its accurate position during the compression process, thereby effectively achieving a seal.

[0059] Please refer to Figure 3 and Figure 5 , Figure 5 which is a schematic structural view of the connecting plate 11 of the embodiment of the present application. In some embodiments, the connecting plate 11 may include a first plate body 113, a second plate body 114 and a third plate body 115 that are sequentially connected. The second plate body 114 is connected to the lamp board 12, and the first plate body 113 and the third plate body 115 extend from one side of the second plate body 114 in a direction away from the lamp board 12.

[0060] In this way, the first plate body 113, the second plate body 114 and the third plate body 115 can also jointly enclose to form an accommodation space 116, and the accommodation space 116 can be used to accommodate at least part of the light guide column 14 and the sleeve 13 so as to play a certain protective role.

[0061] It can be understood that since part of the light guide column 14 and the sleeve 13 are accommodated in the accommodation space 116 of the connecting plate 11, the first plate body 113 and the third plate body 115 cooperate with the second plate body 114 to be able to protect the light guide column 14 and the sleeve 13, and avoid foreign objects directly hitting the sleeve 13 and the light guide column 14. And the accommodation space 116 can isolate some impurities (such as dust or water mist, etc.) from invading into the light guide column 14 and the sleeve 13.

[0062] The three-section setting makes the connecting plate 11 form a structure similar to a "U" shape. Compared with a single-board structure, it can more effectively disperse stress when bearing external forces. When the energy storage power conversion device 100 is shaken, the first plate body 113 and the third plate body 115 can help the second plate body 114 share the impact force, reduce the situation where stress concentrates on the connection part between the second plate body 114 and the lamp board 12, ensure the stability between the lamp board 12 and the connecting plate 11, and reduce the risk of damage.

[0063] The "U"-shaped connecting plate 11 can also be used for wiring. During the process of laying the lines connecting the lamp board 12 and an external power source or other control systems, the accommodation space 116 can be used to accommodate and guide the wires, avoiding the wires from being piled up in a mess, making the wiring more regular and orderly, and facilitating later maintenance and inspection.

[0064] In addition, the additionally extended first plate body 113 and the third plate body 115 can provide an installation platform for mounting other functional modules on the energy storage power conversion device 100. Exemplarily, when a sensor component is arranged in the signal lamp component 10 for detecting the temperature or humidity of the environment, etc., the sensor component can be installed on the first plate body 113 or the third plate body 115, or installed in the accommodation space 116. The connecting plate 11 can not only provide an installation position for the sensor component, but also avoid interference between the sensor component and other components in the energy storage power conversion device 100.

[0065] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of the energy storage power conversion device 100 implemented in this application. This application also provides an energy storage power conversion device 100, which includes a panel 20 and a signal light assembly 10. The signal light assembly 10 is mounted on the panel 20.

[0066] The Power Conversion System (PCS) 100 is one of the core components of an energy storage system. The PCS is used to realize energy conversion and bidirectional flow between the energy storage battery and the power grid.

[0067] The indicator light assembly 10 can be used to display the operating status of the energy storage power conversion device 100, such as charging status, discharging status, or low battery status; the indicator light assembly 10 can also be used as an alarm device for the energy storage power conversion device 100, issuing an alarm through flashing indicator lights or specific color changes. The indicator light assembly 10 can also be used for operation prompts, maintenance prompts, or operating mode switching indications for the energy storage power conversion device 100.

[0068] The panel 20 may have light-transmitting holes, which are correspondingly arranged with the light guide column 14. The light emitted by the light guide column 14 can be emitted to the outside of the energy storage power conversion device 100 through the light-transmitting holes.

[0069] In some embodiments, the sleeve 13 and the panel 20 are integrally formed. The panel 20 can be made of a high-strength, corrosion-resistant metal material. This integral forming can be achieved using a high-precision die-casting process. During die-casting, a specific metal alloy is injected into a mold under high temperature and pressure, allowing the panel 20 and sleeve 13 to be formed in one step, thus ensuring a tight and seamless connection between the two, improving overall integrity and stability.

[0070] In some embodiments, the sleeve 13 can also be installed on the panel 20 by welding. The panel 20 has an internal threaded hole, and one end of the sleeve 13 has an external thread. The sleeve 13 is fixed on the panel 20 by rotating and tightening.

[0071] In some embodiments, the sleeve 13 can also be installed on the panel 20 by means of snap-fit ​​connection, rivet connection, bolt connection, adhesive connection, etc., and there are no restrictions on this.

[0072] In the description of this application, it should be understood that terms such as “first” and “second” are used only to distinguish similar objects and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0073] It should be noted that, in the embodiments of this application, "electrical connection" can be a direct electrical connection between two electrical components or an indirect electrical connection. For example, the electrical connection between A and B can be achieved by A and B being directly connected, or by A and B being indirectly connected through one or more other electrical components.

[0074] The signal light assembly and energy storage power conversion device provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application, and the descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
