[0003] This application relates to the field of energy storage technology, and in particular to panel structures and energy storage devices. Background Technology

[0004] Energy storage products typically have sockets on their panels for plugging in electrical devices. Different countries require different socket standards for energy storage products, and existing products with sockets on their panels result in numerous and complex internal wiring harnesses. Changing to a different socket standard is extremely difficult and inflexible; even if the socket is successfully replaced, it may fail EMC testing, posing a safety risk. Therefore, designing a panel structure with minimal or no internal wiring, easy socket replacement, and reliable operation has become a pressing challenge. Utility Model Content

[0005] Therefore, it is necessary to provide a panel structure to address the issue of high costs associated with energy storage devices adapting to different socket standards.

Detailed Implementation

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] With the widespread application of clean energy, there are more and more types of energy storage products. In order to achieve more functions, existing energy storage devices usually include multiple functional modules that are interconnected to form a multi-purpose energy storage device. The energy storage device is equipped with a socket, and by plugging the plug of the electrical device into the socket, it can provide power to various electrical devices.

[0039] Because each country has different socket structure specifications and standards, energy storage products need to be equipped with different socket panels for different socket standards, which increases costs.

[0040] Based on this, one embodiment of this application provides a panel structure that can accommodate different plug specifications by replacing the socket assembly, thereby improving the flexibility of the panel structure while reducing its development cost, and ultimately enhancing the competitiveness of energy storage devices. The panel structure provided in one embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0041] See Figures 1 to 5 As shown, an embodiment of this application provides a panel structure 100 applied to an energy storage device. The panel structure 100 includes a socket panel 110, a socket assembly 120, and a first connector 131. The socket panel 110 is configured with a first mounting hole 112 and a first mating portion 111. The socket assembly 120 is accommodated in the first mounting hole 112 and is provided with a second mating portion 123. The first connector 131 passes through the second mating portion 123 and the first mating portion 111 in sequence to detachably connect the socket assembly 120 to the socket panel 110.

[0042] In the aforementioned panel structure 100, the socket assembly 120 is detachably mounted on the socket panel 110 via the first connector 131. When it is necessary to replace the socket assembly 120 with a different specification, it is not necessary to re-customize the entire socket panel 110. Simply loosen the first connector 131, replace the old standard socket assembly 120, install the new standard socket assembly 120, and then connect and fix it via the first connector 131. This allows for compatibility with different plug specifications, improving the flexibility of the panel structure 100 while reducing its development cost, thereby enhancing the competitiveness of the energy storage device. The socket assembly 120 is equipped with multiple output ports, enabling it to supply power to multiple electrical devices simultaneously.

[0043] See Figures 3 to 5 As shown, in one embodiment, the first mating portion 111 of the socket panel 110 protrudes from the second mating portion 123 with a first latching block 1111. The first latching block 1111 and the first mating portion 111 cooperate to form a stepped latching end face. The second mating portion 123 is correspondingly provided with a stepped end face, thereby abutting against the latching end face. Thus, the stepped latching end face can guide the insertion operation, allowing the socket assembly 120 to move along... Figure 5 The vertical movement shown limits the movement trajectory of the socket assembly 120 during installation, thereby enabling blind insertion of the socket assembly 120, greatly reducing installation difficulty and saving installation time. Simultaneously, the abutment cooperation between the stepped end face and the snap-fit ​​end face further increases the contact area between the socket panel 110 and the socket assembly 120, improving the connection effect and stability between them. Combined with the first connector 131, this ensures the stability and reliability of the socket assembly 120 installed on the socket panel 110. Figure 5 From the perspective shown, the step end face can further limit the second mating part 123 in the left and right directions, further reducing the possibility of the socket assembly 120 becoming loose or displaced after being installed on the socket panel 110.

[0044] like Figure 2 As shown, the socket assembly 120 includes a first socket 121 and a socket bracket 122 for fixing the first socket 121. The first socket 121 is specifically an AC socket for plugging in the plug of an electrical device, so that the energy storage device can provide power to the electrical device. The aforementioned second mating part 123 is provided on the socket bracket 122, and the socket bracket 122 is connected to the socket panel 110.

[0045] Furthermore, the socket assembly may also include an overcurrent protector (not shown in the figure), which can be electrically connected to the first socket to provide overcurrent protection when the battery module is charged using the first socket. The overcurrent protector is provided with a reset button, which, when pressed, restores the circuit to normal connectivity.

[0046] In some embodiments, the socket assembly may include a power switch (not shown) for controlling the on / off state of the entire energy storage device. Controlling the on / off state of the entire energy storage device with a power switch can effectively save energy. With conventional energy storage devices, if the electrical load is in standby mode, the user may forget to unplug it, unaware that the load is in use. With a power switch, the user only needs to operate the power switch when the energy storage device is not in use, which is convenient and simple.

[0047] See Figure 2 and Figure 4 As shown, in one embodiment, the exposed end face of the socket assembly 120 is flush with the end face of the socket panel 110. That is, the socket assembly 120 does not protrude outwards. This arrangement improves the overall flatness and aesthetics of the panel structure 100.

[0048] See Figure 2 and Figure 5 As shown, in one embodiment, the panel structure 100 further includes an adapter plate 140 electrically connected to the socket assembly 120. The adapter plate 140 has conductive contacts that contact fixed conductive contacts inside the socket assembly 120, forming a current path. When a plug is inserted into the socket assembly 120, the conductive contacts on the adapter plate 140 contact the conductive contacts on the main board 150, thereby establishing a current path. On one hand, the adapter plate 140 prevents the conductive contacts from being directly exposed before the plug is fully inserted, reducing the risk of electric shock. The design of the adapter plate 140 ensures that the conductive contacts only contact when the plug is fully inserted, thus increasing safety. On the other hand, the adapter plate 140 can also be equipped with a self-locking mechanism to ensure a secure connection between the plug and the socket assembly 120, preventing accidental disconnection. It should also be noted that a creepage distance compliant with safety regulations is provided between the adapter plate and electronic components to avoid short circuits and damage to components.

[0049] The adapter board 140 serves as a connector and converter in the energy storage device, ensuring compatibility and safety between the internal and external electrical equipment, while also improving the flexibility and adaptability of the energy storage device. Simultaneously, the adapter board 140 simplifies the connection process between external electrical equipment and the energy storage device, simplifying wiring and installation through standardized interfaces. This allows the energy storage device to more easily adapt to different application scenarios, such as different types of loads or different power input specifications. Furthermore, by plugging and unplugging the socket assembly 120 to the adapter board 140, it can replace the traditional wiring structure, solving the problems of complex wiring and internal clutter caused by numerous wire harnesses. This further avoids the inconvenience caused by wiring during assembly and maintenance, eliminates safety hazards associated with wiring, and reduces the cost added by using wire harnesses, thereby enhancing the competitiveness of the energy storage device.

[0050] See Figure 5 As shown, in one embodiment, the socket assembly 120 is provided with a connection through hole 125 for the first connector 131 to pass through. By providing the connection through hole 125 on the socket assembly 120, a disassembly tool can be easily inserted into the connection through hole 125 to connect with the first connector 131 during disassembly or installation of the socket assembly 120. This allows the first connector 131 to be loosened or tightened using the disassembly tool, facilitating the removal or tightening of the socket assembly 120. Specifically, the first connector 131 can be a screw, and the disassembly tool can be a screwdriver. Furthermore, the screw cap may have a slotted, Phillips, or other shaped opening to facilitate screwdriver rotation.

[0051] See Figure 5 As shown, in one embodiment, the socket assembly 120 is provided with a grounding through-hole 124 for a grounding component 133 to pass through, so that the grounding component 133 can be connected to the adapter plate 140. Connecting the grounding component 133 to the adapter plate 140 not only achieves grounding connection but also helps release static electricity, preventing sparks caused by static accumulation from igniting fires or explosions, ensuring the safe operation of the energy storage device under various conditions, and improving the stability and safety of the energy storage device. The grounding through-hole 124 allows for easy insertion of a disassembly tool into the grounding through-hole 124 to connect with the grounding component 133 during disassembly or installation of the socket assembly 120, allowing the grounding component 133 to be loosened or tightened using the disassembly tool. The grounding component 133 can specifically be a grounding screw, typically made of a material with good conductivity, such as copper or copper-plated steel. The grounding screw should be tightened to sufficient force to ensure good contact with the metal casing. All exposed weld points and grounding screws should be treated with anti-corrosion measures to prevent corrosion. Grounding screws or terminals are usually clearly marked for easy identification.

[0052] See Figure 2 , Figure 3 , Figure 5 As shown, in one embodiment, the panel structure 100 further includes a first sealing member 132, which is inserted into the grounding via 124 and the connection via 125. Specifically, the first sealing member 132 can be a plug made of rubber or silicone. By sealing the grounding via 124 and the connection via 125 with the first sealing member 132, the sealing performance of the grounding member 133 located in the grounding via 124 and the first connector 131 located in the connection via 125 is ensured, thereby preventing dust and moisture from entering the energy storage device through the connection via 125 and the grounding via 124, and improving the waterproof and dustproof effect of the energy storage device. Specifically, in this embodiment, the first sealing member 132 can be elongated. A sealing hole is provided on the socket bracket 122, connecting the connection via 125 and the grounding via 124. The first sealing member 132 is installed inside the sealing hole, thereby sealing the connection via 125 and the grounding via 124. Understandably, when the socket assembly 120 needs to be disassembled, the first sealing member 132 must be removed first. In other embodiments, two first sealing members 132 can be provided, eliminating the need for a separate sealing hole connecting the grounding via 124 and the connection via 125. The two first sealing members 132 respectively seal the connection via 125 and the grounding via 124, thus achieving a seal between them.

[0053] like Figure 7 As shown, in one embodiment, the panel structure 100 further includes a main board 150, which is electrically connected to the adapter board 140 via an electrical connector. The main board 150 is connected to the internal circuitry of the energy storage device, such as a battery module or charging controller, and serves as the interface between the energy storage device and an external load. The main board 150 has fixed conductive contacts connected to the internal circuitry of the energy storage device. When the conductive contacts on the adapter board 140 contact the conductive contacts on the main board 150, the conductive contacts on the main board 150 transfer current from the energy storage device to the plug. Through the cooperation of these components, the socket assembly 120 in the panel structure 100 achieves a safe and reliable electrical connection, ensuring effective interaction between the energy storage device and the external load. The main board 150 is typically made of insulating material to ensure electrical isolation from the internal circuitry of the energy storage device, preventing short circuits and accidental electric shock.

[0054] Specifically, connecting the mainboard 150 and the adapter board 140 via an electrical connector can replace the traditional wiring structure, solving the problems of complex wiring and disorganized internal equipment caused by numerous wire harnesses. This further avoids the inconvenience of wiring for assembly and maintenance, eliminates safety hazards associated with wiring, and reduces the cost of using wire harnesses, thereby enhancing the competitiveness of energy storage equipment. Specifically, the electrical connector includes a male connector 141 on the adapter board 140 and a female connector 151 on the mainboard 150. One of the male connector 141 and the female connector 151 has protruding pins, and the other has a recessed hole. Electrical connection between the mainboard 150 and the adapter board 140 is achieved through the insertion of the pins and the hole.

[0055] In existing technologies, the internal components of energy storage devices are mostly connected by wires, resulting in a redundant and messy wiring layout. This makes wiring errors during installation highly likely and difficult to troubleshoot, increasing installation difficulty. Furthermore, the complex wiring occupies a significant amount of internal space, affecting heat dissipation and potentially causing overheating and safety hazards. This application connects the mainboard 150 to the adapter board 140 using a male connector 141 and a female connector 151, replacing the traditional wiring structure and achieving a wireless design. This solves the problems of complex wiring and internal clutter caused by numerous wires, further avoiding the inconvenience of wiring during assembly and maintenance, eliminating safety hazards associated with wiring, and reducing the cost of using wires, thus enhancing the competitiveness of energy storage devices.

[0056] See Figure 2 and Figure 7 As shown, in one embodiment, the panel structure 100 further includes a mating sleeve 160, which is fitted over the outside of the electrical connector. By providing the mating sleeve 160, the safe and reliable transmission of electrical energy between the components is ensured. Simultaneously, the mating sleeve 160 provides additional protection against external factors (such as dust, moisture, chemicals, etc.) affecting electrical components, and also serves as insulation, reducing the risk of electrical short circuits. Furthermore, the mating sleeve 160 typically possesses a certain degree of mechanical strength to protect the internal electrical connections from mechanical shocks or vibrations, ensuring connection stability.

[0057] See Figure 2 and Figure 7As shown, the panel structure 100 also includes a support member 170, which is disposed between the main board 150 and the adapter board 140. The support member 170 defines the insertion trajectory of the male connector 141 and the female connector 151, thereby enabling blind insertion of the male connector 141 and the female connector 151. This avoids the risk of pin bending due to positional deviation during insertion, reduces the difficulty of insertion between the main board 150 and the adapter board 140, and greatly saves installation time, enabling quick assembly and disassembly.

[0058] The support component 170 is specifically a sheet metal support. On one hand, the sheet metal support provides a solid structural support for the panel structure 100, ensuring the stability and mechanical strength of the entire energy storage device. This helps prevent damage to the energy storage device caused by external forces during transportation, installation, and operation. On the other hand, the support component 170 can be used to fix components such as battery modules and heat sinks, ensuring that each component is in the correct position and reducing the possibility of misalignment or loosening during operation. At the same time, by combining the sheet metal support with heat sinks or cooling systems, the excellent thermal conductivity of the sheet metal can dissipate the heat generated by the battery modules, ensuring that the battery modules operate within a suitable temperature range, improving the performance and lifespan of the battery modules. Furthermore, the sheet metal support can serve as an insulating material, isolating the battery modules from the external environment, reducing the risk of electrical short circuits, and improving the safety of the entire energy storage device.

[0059] When the socket assembly 120 needs to be disassembled in the aforementioned panel structure 100, firstly, use a flat tool or fingernail to remove the first sealing member 132, then loosen the grounding member 133, and then loosen the first connecting member 131 that secures the socket assembly 120, and then remove the socket assembly 120. After obtaining the assembled new socket assembly 120, directly insert it into the socket panel 110, first securing the four first connecting members 131 of the socket assembly 120, and then securing the grounding member 133, thus completing the replacement of the socket assembly 120. The socket assembly 120 can be customized according to plugs from various countries, the mold is small, the mold cost is low, and there is no need to re-customize the entire socket panel 110, reducing the development cost of the panel structure 100 and thus enhancing the competitiveness of the energy storage device.

[0060] Furthermore, one embodiment of this application also provides an energy storage device, including the panel structure 100 as described above. For example... Figure 1 and Figure 2As shown, in some embodiments, the energy storage device further includes a middle frame 210, which is composed of four side panels sequentially spliced ​​together. The multiple side panels cooperate to form an accommodating space for accommodating the support member 170 and main board 150, etc., in the above embodiments. The middle frame 210 is connected to the socket panel 110. Furthermore, the energy storage device also includes a rear shell 220 connected to the middle frame 210. The rear shell 220 and the socket panel 110 seal the opening of the accommodating space, improving the aesthetics of the energy storage device, while also improving the waterproof and dustproof performance of each component and extending the service life of the energy storage device.

[0061] Specifically, the edge of the middle frame 210 is provided with a connecting part, which includes one or both of a snap-fit ​​part and a threaded connection part. The connecting part is used to connect the panel structure 100 and the back cover 220. The snap-fit ​​or screw connection facilitates easy disassembly and assembly, making it convenient in both use and production assembly. Furthermore, the middle frame 210 may also include reinforcing ribs (not shown in the figure) to increase the strength of the middle frame 210. Figure 1 and Figure 2 As shown, a handle 250 is further provided on the middle frame 210 to facilitate the transfer of the energy storage device to different locations. The rear shell may have anti-slip textures (not shown) to prevent slippage when placing the energy storage device.

[0062] Understandably, the energy storage device also includes a battery module (not shown). The battery module is housed within the accommodating space formed by the mid-frame 210 and is protected by the panel structure 100 and the rear shell 220 to prevent damage to the battery module during use. The battery module is used to store electrical energy and supply power to the outside world, and may specifically include at least one of zinc-manganese batteries, zinc-silver batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lead-acid batteries, lithium-magnesium batteries, zinc-manganese batteries, alkaline manganese batteries, and lithium batteries. Specifically, the battery module can be charged by the outside world through the panel structure 100, and the battery module can also supply power to the outside world through the panel structure 100. The battery module can be fixed to the panel structure 100 or the rear shell 220 by screws, bolts, or nuts.

[0063] Specifically, the battery module includes a cell module, a sampling board, and an inverter mainboard. The cell module includes multiple cells and a bracket for fixing the cells. The sampling board is fixedly connected to the bracket, and the inverter mainboard is electrically connected to the sampling board via plug-in terminals. The inverter mainboard is a PCB board that integrates an inverter circuit that converts DC to AC, controlling parameters such as the amplitude, frequency, and phase of the AC voltage. The electrodes of the cell module are electrically connected to the inverter circuit on the inverter mainboard. The sampling board is also a PCB board that integrates a sampling circuit. This sampling circuit monitors the output current of the energy storage device and adjusts the inverter's output voltage or current based on the feedback signal, ensuring the inverter operates normally and outputs a stable voltage and / or current. Since the inverter circuit and sampling circuit are mature technologies in the electrical field, they will not be described in detail in this embodiment.

[0064] Since the inverter circuit is integrated into the inverter motherboard and the sampling circuit is integrated into the sampling board, the inverter motherboard and the sampling board are connected by plugging in the terminals to achieve electrical connection between them. This modularizes the product, simplifies the internal structure, and makes the product easy and convenient to assemble. The plug-in structure of the terminals replaces the traditional wiring structure, further avoiding the inconvenience of wiring for assembly and maintenance, and eliminating safety hazards during use.

[0065] Specifically, the plug-in terminals include male and female terminals. The male terminal is fixedly mounted on the sampling board, and the female terminal is fixedly mounted on the inverter mainboard. The male terminal is electrically connected to the sampling circuit, and the female terminal is electrically connected to the inverter circuit. The electrical connection between the sampling board and the inverter mainboard is achieved by plugging in the male and female terminals.

[0066] like Figure 1 and Figure 4 As shown, in some embodiments, both the aforementioned mid-frame 210 and panel structure 100 are provided with heat dissipation holes 230, and a cooling fan 240 is provided inside the accommodating space. The cooling fan 240 removes the heat generated inside the energy storage device by forcing airflow, ensuring that key components such as battery modules and electronic components are kept within a suitable operating temperature range, thereby improving the overall efficiency and lifespan of the system, helping to achieve a balanced internal temperature distribution, and avoiding local overheating. At the same time, the effective heat dissipation through the cooling fan 240 and heat dissipation holes 230 can reduce the risks of battery expansion and electrolyte leakage caused by overheating, improve the safety and reliability of the energy storage device, reduce the aging rate of battery modules and electronic components, and extend their service life.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
