In addition, when the anti-scalding structure is installed on the outside of the device, it increases the overall thickness of the device, affecting its lightweight design and increasing the space occupied by the device. There is room for improvement. Summary of the Invention

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] The energy storage device 100 according to an embodiment of this application is described below with reference to Figures 1-7. It has a simple structure and low installation cost. It can improve the safety of use of the energy storage device 100 and the heat dissipation of the main housing 1, so as to ensure the operational reliability of the energy storage device 100. It can also improve the lightweight of the energy storage device 100, reduce the space occupied, and improve the user experience.

[0031] As shown in Figures 1-7, an energy storage device 100 according to an embodiment of the present invention includes: a main housing 1 and an anti-scalding plate 4.

[0032] At least one side of the main unit housing 1 has an embedded groove 12, and a heat dissipation cover plate 2 is provided in the embedded groove 12. An anti-scalding plate 4 is installed in the embedded groove 12 and is located outside the heat dissipation cover plate 2. A heat dissipation gap 5 is formed between the anti-scalding plate 4 and the heat dissipation cover plate 2.

[0033] The energy storage device 100 can be configured as a photovoltaic energy storage device, which converts solar energy into electrical energy and stores it to power household appliances or vehicles. The photovoltaic energy storage device integrates a battery pack and a photovoltaic control module. It converts solar energy into electrical energy through photovoltaic panels and other structures and stores it within the battery pack. The photovoltaic energy storage device can be installed in indoor locations such as balconies, allowing users to supply energy to household appliances and improve environmental protection and energy efficiency.

[0034] Specifically, the energy storage device 100 is provided with a main housing 1, which is located on the outermost side of the energy storage device 100. It can support and protect the internal structure of the energy storage device 100 and provide installation points for the internal structure, thereby ensuring the operational reliability of the energy storage device 100. The main housing 1 can be provided with an installation cavity 3, etc., to install the battery pack and other structures, so as to store the electrical energy converted from light energy. When the user needs electricity, the electrical energy stored in the battery pack can be transmitted to the electrical appliance that needs electricity through the wiring harness, thereby improving environmental protection.

[0035] Furthermore, the main housing 1 can be configured as a rectangular structure, and an embedded groove 12 can be formed on at least one side of the main housing 1, that is, embedded grooves 12 can be formed on one, two, or three sides of the main housing 1. The embedded groove 12 is recessed into the main housing 1 and open to the outside of the main housing 1. A heat dissipation cover plate 2 is provided in the embedded groove 12, that is, the heat dissipation cover plate 2 can be set at the bottom of the embedded groove 12. When the energy storage device 100 is running, a large amount of heat energy will be generated inside it, which will make the temperature of the main housing 1 of the energy storage device 100 high. The main housing 1 can conduct heat to the heat dissipation cover plate 2 to dissipate heat and ensure the operational reliability of the energy storage device 100.

[0036] Furthermore, the energy storage device 100 is also equipped with a heat shield 4. The heat shield 4 is designed as a plate structure, which can reduce the space occupied by the heat shield 4. The heat shield 4 is installed in the recessed groove 12 and is located on the outside of the heat dissipation cover 2. That is, the heat shield 4 can shield the heat dissipation cover 2, thereby preventing the user from being burned by the high temperature conducted to the heat dissipation cover 2, thus improving the safety of use. Moreover, installing the heat shield 4 in the recessed groove 12 can reduce the extra space occupied by the heat shield 4, thereby reducing the overall volume of the energy storage device 100 and improving the lightweight of the energy storage device 100.

[0037] In addition, a heat dissipation gap 5 is formed between the anti-scalding plate 4 and the heat dissipation cover plate 2, that is, the anti-scalding plate 4 and the heat dissipation cover plate 2 are set apart. When heat is conducted to the heat dissipation cover plate 2, it can exchange heat with the air to transfer the heat to the outside of the main unit housing 1. The anti-scalding plate 4 and the heat dissipation cover plate 2 are set apart to prevent heat from being conducted to the anti-scalding plate 4, thereby ensuring the reliability of the anti-scalding plate 4 and improving the heat dissipation effect of the heat dissipation cover plate 2. This ensures the operational reliability of the energy storage device 100. Furthermore, the anti-scalding plate 4 can prevent users from being burned by high temperature, improve user safety, and enhance the user experience. The structure is simple and the installation cost is low.

[0038] According to the embodiment of the present utility model, the energy storage device 100, by installing the anti-scalding plate 4 in the embedded recess 12 of the main housing 1, and the embedded recess 12 is provided with a heat dissipation cover plate 2, can prevent the heat dissipation cover plate 2 from scalding the user, thereby improving the safety of use. The anti-scalding plate 4 installed in the embedded recess 12 can be placed inside the energy storage device 100, thereby reducing the space occupied by the anti-scalding plate 4, thereby improving the lightweight of the energy storage device 100 and improving the user experience. In addition, a heat dissipation gap 5 is formed between the anti-scalding plate 4 and the heat dissipation cover plate 2, which can ensure the heat dissipation effect of the heat dissipation cover plate 2, thereby ensuring the operational reliability of the energy storage device 100, with better use effect and wider application range.

[0039] In some embodiments, the heat dissipation cover 2 is provided with a heat dissipation portion 21 protruding toward the anti-scalding plate 4, and there are at least two heat dissipation portions 21; wherein, the heat dissipation portion 21 is constructed as a strip, and a heat conduction groove 22 is formed between two adjacent heat dissipation portions 21, and at least one end of the heat conduction groove 22 along the length direction is constructed as an open end.

[0040] Specifically, the heat dissipation cover 2 is set in the embedded groove 12 to ensure the operational reliability of the energy storage device 100. As shown in Figures 1-3 and 6, the heat dissipation cover 2 is provided with a heat dissipation part 21. The heat dissipation part 21 is set on the side of the heat dissipation cover 2 near the anti-scalding plate 4, and the heat dissipation part 21 protrudes towards the anti-scalding plate 4. There are at least two heat dissipation parts 21, that is, there can be two, three or four heat dissipation parts 21. The heat dissipation part 21 protrudes from the surface of the heat dissipation cover 2, which can increase the surface area of ​​the heat dissipation cover 2, thereby increasing the area for heat exchange between the heat dissipation cover 2 and the airflow, so as to improve the heat exchange effect of the heat dissipation cover 2.

[0041] Furthermore, the heat dissipation part 21 is configured to protrude towards the anti-scalding plate 4, and the anti-scalding plate 4 is provided with heat dissipation holes 41, so that the airflow flowing through the heat dissipation holes 41 to the heat dissipation cover plate 2 can exchange heat with the heat dissipation part 21. Moreover, there are at least two heat dissipation parts 21, that is, the airflow can exchange heat with at least two heat dissipation parts 21, thereby increasing the heat exchange speed and improving the heat dissipation speed of the heat dissipation cover plate 2, and ensuring the operational reliability of the energy storage device 100.

[0042] In addition, the heat dissipation part 21 is configured as a long strip structure protruding from the surface of the heat dissipation cover plate 2 toward the anti-scalding plate 4, which can increase the surface area of ​​the heat dissipation part 21 and improve the heat dissipation effect. A heat conduction groove 22 can be formed between two adjacent heat dissipation parts 21. The heat conduction groove 22 is open toward the anti-scalding plate 4. At least one end of the heat conduction groove 22 along the length direction is constructed as an open end. That is, one end of the heat conduction groove 22 along the length direction can be constructed as an open end, or both ends of the heat conduction groove 22 along the length direction can be constructed as open ends. This allows the heat conduction groove 22 to communicate with the embedded sink 12, so that the high-temperature airflow after heat exchange can be discharged from the embedded sink 12 through the open end, ensuring the reliability of heat exchange. When there is water flow outside, the water flow can flow through the heat conduction groove 22 and then be discharged from the embedded sink 12 through the open end, so as to prevent the water flow into the energy storage device 100 and ensure the operational reliability of the energy storage device 100.

[0043] In some embodiments, both ends of the heat-conducting groove 22 along its length are configured as open ends.

[0044] Specifically, the heat conduction groove 22 is formed between two adjacent heat dissipation parts 21 and is open to the anti-scalding plate 4 to exchange heat with the airflow. Both ends of the heat conduction groove 22 along its length are constructed as open ends. When the external airflow flows through the heat dissipation hole 41 toward the heat dissipation cover plate 2, the airflow can exchange heat with the heat dissipation part 21 of the heat dissipation cover plate 2. The airflow after heat exchange can flow along the heat conduction groove 22 and then flow from the open ends of the heat conduction groove 22 to the outside of the embedded sink 12, thereby improving the airflow flow, improving the heat dissipation effect, and ensuring the operational reliability of the energy storage device 100.

[0045] In other embodiments, the inner bottom wall 221 of the heat conduction groove 22 is configured to extend downward toward the open end along the length of the heat conduction groove 22.

[0046] Specifically, the heat conduction groove 22 is open towards the anti-scalding plate 4 and recessed towards the heat dissipation cover plate 2, so that the side of the heat conduction groove 22 away from the anti-scalding plate 4 has an inner bottom wall 221. The inner bottom wall 221 of the heat conduction groove 22 is constructed to extend downward towards the open end along the length of the heat conduction groove 22. That is, the inner bottom wall 221 in the middle of the heat conduction groove 22 has the highest setting height, and the inner bottom wall 221 at both ends of the heat conduction groove 22 has the lowest setting height. This allows the airflow to flow along the inner bottom wall 221 to both ends of the heat conduction groove 22 after flowing into the heat conduction groove 22, thereby increasing the airflow speed. When water flows into the heat conduction groove 22, it can flow along the inner bottom wall 221 to both ends of the heat conduction groove 22, thereby draining the water into the settling tank 12, ensuring the reliability of drainage, and improving the operational reliability of the energy storage device 100.

[0047] In some embodiments, a plurality of heat dissipation portions 21 are provided, and the plurality of heat dissipation portions 21 together define a plurality of heat conduction grooves 22, which are distributed in parallel and spaced apart.

[0048] Specifically, the heat dissipation part 21 is disposed on the side of the heat dissipation cover plate 2 near the anti-scalding plate 4, and as shown in Figures 1-3 and 6, there are multiple heat dissipation parts 21, that is, there can be two, three or four heat dissipation parts 21, etc. Two adjacent heat dissipation parts 21 can jointly define the heat conduction groove 22. There are multiple heat dissipation parts 21, that is, multiple heat dissipation parts 21 can jointly define multiple heat conduction grooves 22. The multiple heat dissipation parts 21 are distributed in parallel and spaced apart, so that the multiple heat conduction grooves 22 are also distributed in a spaced apart manner.

[0049] Thus, by providing multiple heat dissipation sections 21 and multiple heat conduction grooves 22 on the side of the heat dissipation cover plate 2 near the anti-scalding plate 4, the total area of ​​the side of the heat dissipation cover plate 2 near the anti-scalding plate 4 can be increased, thereby increasing the contact area between the heat dissipation cover plate 2 and the external airflow. Furthermore, by forming multiple heat conduction grooves 22, the heat-exchanged airflow can flow outward from the embedded groove 12 through the multiple heat conduction grooves 22, thereby increasing the airflow velocity and thus improving the heat dissipation effect of the heat dissipation cover plate 2, ensuring the operational reliability of the energy storage device 100.

[0050] In addition, multiple heat conduction grooves 22 are formed, so that the water flowing to the heat dissipation cover plate 2 can flow out of the embedded sink 12 through the multiple heat conduction grooves 22 respectively, so as to avoid water accumulation in the embedded sink 12 and flowing into the energy storage device 100, which would cause leakage or other problems in the energy storage device 100, thereby ensuring the operational reliability of the energy storage device 100.

[0051] In some embodiments, the heat dissipation part 21 is configured to extend along the length direction of the heat dissipation cover plate 2, and a plurality of heat conduction grooves 22 are spaced apart along the width direction of the heat dissipation cover plate 2.

[0052] Specifically, the heat dissipation part 21 is constructed as a long strip and protrudes from the surface of the heat dissipation cover plate 2 toward the anti-scalding plate 4. The main body housing 1 can be configured as a rectangular body, that is, the heat dissipation cover plate 2 is also constructed as a rectangular plate. The heat dissipation part 21 is disposed on the surface of the heat dissipation cover plate 2 and can extend along the length direction of the heat dissipation cover plate 2, thereby increasing the total surface area of ​​a single heat dissipation part 21. Multiple heat dissipation parts 21 are configured, and multiple heat dissipation parts 21 are all extended along the length direction of the heat dissipation cover plate 2 and spaced apart along the width direction of the heat dissipation cover plate 2, thereby maximizing the increase of the total surface area of ​​the heat dissipation cover plate 2 to improve the heat dissipation effect of the heat dissipation cover plate 2.

[0053] Furthermore, a heat conduction groove 22 is defined between two adjacent heat dissipation parts 21, that is, multiple heat conduction grooves 22 are also provided. Multiple heat conduction grooves 22 are also extended along the length direction of the heat dissipation cover plate 2 and spaced apart along the width direction of the heat dissipation cover plate 2. This can increase the surface area of ​​the heat dissipation cover plate 2 and improve the guiding effect of airflow and water flow, so as to ensure the operational reliability of the energy storage device 100.

[0054] In some embodiments, the anti-scalding plate 4 is provided with heat dissipation holes 41 that communicate with the heat dissipation gap 5. The heat dissipation holes 41 are constructed as elongated holes, and the length direction of the heat dissipation holes 41 intersects with the length direction of the heat conduction groove 22.

[0055] Specifically, the anti-scalding plate 4 is provided with heat dissipation holes 41, which penetrate the anti-scalding plate 4 and are connected to the heat dissipation gap 5. This allows airflow from the side of the anti-scalding plate 4 away from the heat dissipation cover plate 2 to flow to the anti-scalding plate 4 through the heat dissipation holes 41 for heat exchange with the heat dissipation cover plate 2. The airflow after heat exchange can then flow through the heat dissipation holes 41 to a location away from the energy storage device 100, thus ensuring the heat dissipation effect of the heat dissipation cover plate 2. Furthermore, the heat dissipation holes 41 are designed as elongated holes, which increases the opening area of ​​the heat dissipation holes 41 and increases the airflow at the heat dissipation holes 41. This increases the airflow to the surface of the heat dissipation cover plate 2, thereby ensuring the speed of heat exchange between the heat dissipation cover plate 2 and the airflow, and improving the heat dissipation effect of the heat dissipation cover plate 2.

[0056] Furthermore, the length direction of the heat dissipation hole 41 is set to intersect with the length direction of the heat conduction groove 22. This means that the length direction of the heat dissipation hole 41 and the length direction of the heat conduction groove 22 can be set to form an angle, or the length direction of the heat dissipation hole 41 and the length direction of the heat conduction groove 22 can be set to be perpendicular to each other. This allows the airflow flowing to the heat dissipation hole 41 to flow towards the multiple heat conduction grooves 22 respectively, so that the airflow can exchange heat with the multiple heat conduction grooves 22 and the heat dissipation part 21 respectively, thereby improving the heat exchange efficiency. It also allows the water flowing to the heat dissipation hole 41 to flow towards the multiple heat conduction grooves 22 respectively, so that it can flow out of the embedded sink 12 through the multiple heat conduction grooves 22 respectively, thereby improving the drainage speed.

[0057] In some embodiments, there are multiple heat dissipation holes 41, and the multiple heat dissipation holes 41 are spaced apart along the length direction of the heat conduction groove 22.

[0058] Specifically, as shown in Figures 1 and 4-5, the anti-scalding plate 4 is provided with heat dissipation holes 41, and there are multiple heat dissipation holes 41. All of the multiple heat dissipation holes 41 are connected to the heat dissipation gap 5, so that airflow can flow through the multiple heat dissipation holes 41 to the surface of the heat dissipation cover plate 2, thereby increasing the airflow speed and thus increasing the heat exchange speed of the heat dissipation cover plate 2. The multiple heat dissipation holes 41 are spaced apart along the length of the heat conduction groove 22, so that the airflow flowing through the multiple heat dissipation holes 41 to the heat dissipation cover plate 2 can flow evenly to all parts of the heat conduction groove 22 along the length, thereby ensuring the heat dissipation effect of the heat conduction groove 22 at all parts, and thus ensuring the heat dissipation effect of the heat dissipation cover plate 2 at all parts, and improving the reliability of the heat dissipation cover plate 2.

[0059] In some embodiments, the heat dissipation cover 2 is provided with at least one first connecting portion 23, and the anti-scalding plate 4 is provided with at least one second connecting portion 421. The at least one first connecting portion 23 and the at least one second connecting portion 421 are detachably connected in a one-to-one correspondence.

[0060] Specifically, a heat dissipation cover plate 2 is provided in the embedded groove 12 of the main housing 1, and a connecting part 31 is provided in the mounting cavity 3 of the main housing 1. Multiple connecting parts 31 are provided, and the connecting parts 31 extend in a direction perpendicular to the heat dissipation cover plate 2. The connecting part can be inserted into the connecting part 31 from the side away from the heat dissipation cover plate 2, and then connected to the heat dissipation cover plate 2 to ensure the installation reliability of the heat dissipation cover plate 2. The mounting cavity 3 can be sealed by the heat dissipation cover plate 2. Sealing elements can be provided around the heat dissipation cover plate 2 to ensure the reliability of the seal on the mounting cavity 3, thereby preventing water and other substances from entering the energy storage device 100 and ensuring the operational reliability of the energy storage device 100.

[0061] Furthermore, a first connecting part 23 is provided on the side of the heat dissipation cover plate 2 near the anti-scalding plate 4, and a second connecting part 421 is provided on the side of the anti-scalding plate 4 near the heat dissipation cover plate 2. The first connecting part 23 and the second connecting part 421 are detachably connected, that is, the first connecting part 23 and the second connecting part 421 can be connected by snap-fit ​​or plug-in, so that the anti-scalding plate 4 is detachable relative to the heat dissipation cover plate 2, which can improve the convenience of installation, facilitate later maintenance and cleaning, and save maintenance time.

[0062] In addition, the first connecting part 23 is provided as at least one, that is, the first connecting part 23 can be one, two or more, etc. In this embodiment, the first connecting part 23 is provided as two, and the second connecting part 421 is also provided as at least one, that is, the second connecting part 421 can be one, two or more, etc. In this embodiment, the second connecting part 421 is provided as two. At least one first connecting part 23 and at least one second connecting part 421 are provided in a one-to-one correspondence, so that multiple parts of the anti-scalding plate 4 can be connected to the first connecting part 23 of the heat dissipation cover plate 2 through the second connecting part 421, thereby ensuring the reliability of installation.

[0063] When the anti-scalding plate 4 is installed on the heat dissipation cover plate 2, and the anti-scalding plate 4 is subjected to external force, the force can be transmitted to the first connecting part 23 and the second connecting part 421. By setting multiple first connecting parts 23 and second connecting parts 421, the force can be transmitted through multiple first connecting parts 23 and second connecting parts 421 respectively, thereby reducing the effect of the force on each first connecting part 23 and second connecting part 421, improving the service life of the first connecting parts 23 and second connecting parts 421, and ensuring the reliability of the connection between the anti-scalding plate 4 and the heat dissipation cover plate 2.

[0064] In some embodiments, one of the first connecting portion 23 and the second connecting portion 421 is configured as a positioning post, and the other is configured as a positioning slot, wherein the positioning post and the positioning slot are inserted and positioned together.

[0065] Specifically, the anti-scalding plate 4 can be detachably connected to the first connecting part 23 of the heat dissipation cover plate 2 via the second connecting part 421. As shown in Figures 1-3 and 5, one of the first connecting part 23 and the second connecting part 421 is configured as a positioning post, and the other is configured as a positioning slot. That is, the first connecting part 23 can be configured as a positioning post and the second connecting part 421 can be configured as a positioning slot, or the first connecting part 23 can be configured as a positioning slot and the second connecting part 421 can be configured as a positioning post. In this embodiment, the first connecting part 23 is configured as a positioning post and the second connecting part 421 is configured as a positioning slot.

[0066] In this way, the positioning post and the positioning slot are inserted and positioned together. That is, when the anti-scalding plate 4 is installed on the heat dissipation cover plate 2, the positioning slot can be inserted to the outside of the positioning post to detachably install the anti-scalding plate 4 on the heat dissipation cover plate 2. The structure is simple, the setting cost is low, and the installation is convenient. Moreover, the positioning post is set on the side of the heat dissipation cover plate 2 near the anti-scalding plate 4, and the positioning slot is set on the side of the anti-scalding plate 4 near the heat dissipation cover plate 2. This allows the positioning post and the positioning slot to be covered when the anti-scalding plate 4 is installed on the heat dissipation cover plate 2, thereby improving the overall appearance of the energy storage device 100 and improving the user experience.

[0067] As shown in Figure 5, the anti-scalding plate 4 is provided with a mounting part 42, which is spaced apart from the heat dissipation hole 41. The width of the mounting part 42 is set to be greater than the opening width of the heat dissipation hole 41. The second connecting part 421 is provided on the mounting part 42, thereby ensuring the structural strength of the second connecting part 421 and ensuring the reliability of the connection between the anti-scalding plate 4 and the heat dissipation cover plate 2.

[0068] In some embodiments, the top two sides of the main housing 1 are respectively provided with an upwardly extending shielding flange 11, the two shielding flanges 11 are spaced apart and distributed opposite each other to jointly define the embedded recess 12, and the anti-scalding plate 4 is spaced apart from the shielding flanges 11.

[0069] Specifically, the main housing 1 is provided with an embedded recess 12, and the heat dissipation cover 2 can be installed in the embedded recess 12. As shown in Figures 1 and 2, a shielding flange 11 is provided on each of the top two sides of the main housing 1. The shielding flange 11 extends upward, so that the two shielding flanges 11 are spaced apart on the top two sides of the main housing 1, and the two shielding flanges 11 can jointly define the embedded recess 12, so that the two shielding flanges 11 are higher than the heat dissipation cover 2. When the anti-scalding plate 4 is installed on the heat dissipation cover 2, the two shielding flanges 11 can shield at least part of the anti-scalding plate 4, thereby improving the overall integrity of the energy storage device 100 and improving the user experience.

[0070] Furthermore, the two sides of the anti-scalding plate 4 can be spaced apart from the shielding flange 11, so that the anti-scalding plate 4 can only be connected to the first connecting part 23 of the heat dissipation cover plate 2 through the second connecting part 421, so as to prevent the heat dissipation cover plate 2 and the shielding flange 11 from transferring heat to the anti-scalding plate 4, thereby ensuring the reliability of the anti-scalding plate 4. In addition, the gap between the anti-scalding plate 4 and the shielding flange 11 can also improve the airflow effect, ensure the heat dissipation effect of the heat dissipation cover plate 2, and ensure the operational reliability of the energy storage device 100.
