Technical Field
[0001] The utility model relates to the field of energy storage, and more particularly, to an energy storage housing and an energy storage device. Background Art
[0002] The application scenarios of mobile energy storage power supplies are gradually increasing. An inverter is usually arranged in a mobile energy storage power supply. In outdoor scenarios, due to direct sunlight, its temperature will be too high. At this time, the temperature of the inverter housing will rise extremely, and users may be scalded when touching the housing. At the same time, the working efficiency of the inverter under high temperature conditions is low. In related technologies, a high-temperature overheat protection circuit module, a temperature control module, etc. are provided. However, when there are problems in the internal circuit of the mobile energy storage power supply, the above modules cannot be independently displayed to users. Summary of the Utility Model
[0003] In order to solve or improve the above technical problem that the temperature of the inverter is too high and affects the safety of users.
[0004] An object of the utility model is to provide an energy storage housing.
[0005] Another object of the utility model is to provide an energy storage device.
[0006] To achieve the above object, a first aspect of the utility model provides an energy storage housing, comprising: a housing body, in which a first cavity for accommodating an inverter is provided; a temperature sensing member disposed on a part of the housing body that encloses to form the first cavity; wherein, at least the first color and the second color are included in the color of the side of the temperature sensing member exposed outside the housing body, and the ambient temperature corresponding to the temperature sensing member being the first color is different from the ambient temperature corresponding to the temperature sensing member being the second color.
[0007] According to the energy storage housing provided by the utility model, it includes a housing body and a temperature sensing member, and the color change of the temperature sensing member can indicate the change of the internal temperature of the housing. When the temperature reaches a specific threshold, the color of the temperature sensing member will change from the first color to the second color. Through the visual color change, users can intuitively understand the working state of the device, that is, whether the current temperature is too high, so as to reduce the scald caused by touching, and at the same time remind users that the current temperature is too high and the operation of the inverter may be limited.
[0008] Specifically, a first cavity is provided in the housing body, which is specifically used to accommodate the inverter, ensuring the stability and safety of the inverter during use. Under the action of the housing body, the internal components (such as the inverter) can be effectively protected from the external environment.
[0009] The first cavity is enclosed by a part of the structure of the housing body. By setting the temperature sensing member at a position corresponding to the first cavity, the temperature sensing member can be used to change color according to the change of the surrounding ambient temperature. When the temperature reaches the set threshold, the color change of the temperature sensing member can attract the attention of users.
[0010] Among them, the connection between the temperature-sensing component and the housing body must ensure that it can be exposed to the external environment for easy viewing by the user. At the same time, it is also necessary to ensure that the temperature-sensing component can sense the temperature change in the first cavity, so as to ensure the accuracy of the color change timing.
[0011] Among them, the temperature-sensing component can be integrated into a part of the housing body to ensure that the side exposed outside the housing.
[0012] The temperature-sensing component changes color with temperature. Specifically, the colors that the temperature-sensing component can change can be only two colors, namely the first color and the second color. Of course, on this basis, the number of color changes can be increased, and even the specific color change process can be a gradual change to meet different usage requirements.
[0013] For example, the first color (such as blue) may represent the safe temperature range, while the second color (such as red) represents the warning state of too high temperature.
[0014] The temperature-sensing component should be set on the outside of the housing body so that the user can see the color change, and at the same time, it should be close to the part that may generate heat (such as the inverter) to ensure that it can accurately and timely sense the temperature change.
[0015] This solution can ensure that the temperature-sensing component can effectively sense the temperature change and provide intuitive temperature information to the user through the color change. This design not only improves the safety of the product but also enhances the user experience.
[0016] In addition, the above technical solution provided by the present utility model may also have the following additional technical features:
[0017] In the above technical solution, the housing body includes: a box body, a cover plate is provided on the box body, and the first cavity is located in a part of the box body close to the cover plate; among them, the temperature-sensing component is provided on the cover plate.
[0018] In this technical solution, the housing body includes a box body and a cover plate. By setting the temperature-sensing component on the cover plate, the efficiency of temperature sensing and user feedback can be optimized. Among them, under the action of the cover plate, it can play a role in enclosing and protecting the internal inverter. By combining the cover plate with the box body, the overall structure becomes more compact and firm, and can effectively prevent external substances (such as dust or liquid) from entering the box body to protect the internal electronic components and battery components.
[0019] It should be emphasized that in this solution, by placing the temperature-sensing component on the cover plate, the specific setting position is near the top of the device or the visible area outside.
[0020] The temperature-sensitive component is set on the cover plate. When the internal components (such as the inverter) generate heat, the temperature-sensitive component can sense the temperature rise faster. In addition, the temperature-sensitive component is in a position that is easily observable by the user. The color change caused by the temperature change can be directly seen by the user, enhancing the warning effect and use safety of the device.
[0021] Furthermore, the cover plate is usually connected to the box body by hinges, screws or other fixing methods. This connection ensures that the cover plate can be firmly fixed on the box body, and at the same time allows the cover plate to be opened when necessary for maintenance or inspection.
[0022] The temperature-sensitive component is installed on the cover plate by bonding, embedding or other fixing methods. The connection of the temperature-sensitive component must ensure that it fits closely to the surface of the cover plate to ensure that it can effectively conduct and sense temperature changes.
[0023] The first cavity is located in the part of the box body close to the cover plate. Such a design makes the distance between the cover plate and the key internal components (such as the inverter) shorter, which helps the rapid conduction of heat and the response of the temperature-sensitive component.
[0024] Furthermore, the temperature-sensitive component is located in an obvious area at the center or edge of the cover plate, ensuring that it is easy to observe and not easily blocked.
[0025] Through the newly added cover plate and the layout of the temperature-sensitive component on the cover plate, the overall design of the energy storage housing has been further optimized in terms of temperature monitoring and user safety prompts. As an important protective part of the housing, the cover plate not only provides a reliable installation surface, but also improves the efficiency of temperature sensing and the visual warning effect through the combination with the temperature-sensitive component.
[0026] In the above technical solution, the temperature-sensitive component includes temperature-sensitive discoloring powder, and the temperature-sensitive component is integrally injection-molded with the cover plate.
[0027] In this technical solution, the temperature-sensitive component is in powder form, specifically including temperature-sensitive discoloring powder, which can change color according to the temperature change. By observing the color change of the temperature-sensitive component, the user can intuitively understand the temperature situation of the device. The temperature-sensitive component is integrally injection-molded with the cover plate, forming an integral structure between the two, enhancing the connection strength and stability between the temperature-sensitive component and the cover plate.
[0028] Integral injection molding can ensure the sealing performance between the temperature-sensitive component and the cover plate, prevent dust, moisture, etc. from entering, and protect the internal components.
[0029] In the above technical solution, the temperature-sensitive component includes temperature-sensitive discoloring powder, the temperature-sensitive component is sprayed on at least part of the outer surface of the cover plate, and / or the temperature-sensitive component is screen-printed on at least part of the outer surface of the cover plate.
[0030] In this technical solution, the temperature sensing element is in powder form, specifically thermochromic powder, which can be mixed with paint and then arranged on part of the outer surface of the cover plate or the entire outer surface of the cover plate by at least one of spraying and silk-screen printing, so that the cover plate has the function of changing color with temperature. Specifically, the thermochromic powder can change color according to the change of temperature. By observing the color change of the temperature sensing element, the user can intuitively understand the temperature of the device. Spraying or silk-screen printing can evenly apply the thermochromic powder on the outer surface of the cover plate to achieve sensitive detection of temperature. The processing method of spraying or silk-screen printing is relatively flexible and suitable for covers of various shapes and sizes.
[0031] At the same time, through spraying or screen printing, the thermochromic powder forms good adhesion with the surface of the cover, ensuring that the temperature sensing element is not easy to fall off or be damaged during use. In addition, the temperature sensing element is accurately applied to a specific area of the cover.
[0032] The above technical solution also includes: a mounting groove, which is provided on the part of the shell body that encloses and forms the first cavity, and the temperature sensing component is located in the mounting groove.
[0033] In this technical solution, by setting the mounting groove on the shell body, specifically on the part of the shell body that encloses and forms the first cavity, and setting the temperature sensing element in the mounting groove, the mounting groove can enable the temperature sensing element to be stably placed on the shell body, thereby preventing the temperature sensing element from being displaced or falling off during use. In addition, by installing the temperature sensing element in the mounting groove, it can be ensured that there is good contact between the temperature sensing element and the shell body, so as to more accurately sense the temperature change of the shell body. The close combination of the temperature sensing element and the mounting groove enables the temperature sensing element to respond to the temperature change of the shell body more quickly, thereby improving the accuracy and timeliness of temperature detection.
[0034] In the above technical solution, the thermal conductivity of the groove bottom of the installation groove and / or the groove wall of the installation groove is greater than the thermal conductivity of the shell body.
[0035] In this technical solution, the inner wall surface of the mounting groove, that is, the groove bottom and the groove wall, has good thermal conductivity, which is greater than the thermal conductivity of the shell body. The groove bottom and / or groove wall of the mounting groove have better thermal conductivity, which can transfer the heat inside the shell body to the temperature sensing component more quickly. The temperature sensing component senses the temperature change more quickly, thereby improving the timeliness and accuracy of temperature monitoring.
[0036] Due to the better thermal conductivity of the mounting slot, the temperature sensor can more sensitively sense small changes in temperature. This makes the temperature monitoring system more sensitive and can issue warnings at an early stage of abnormal temperature changes, helping users take timely measures to avoid potential problems.
[0037] It can be understood that better thermal conductivity can reduce the influence of the temperature gradient, enabling the temperature detected by the temperature sensing element to more accurately reflect the actual temperature inside the housing body.
[0038] Among them, the bottom and / or the wall of the installation groove have high thermal conductivity, which can significantly improve the temperature transfer efficiency and detection sensitivity, and play a positive role in optimizing the reliability, safety, and performance of the device.
[0039] In the above technical solution, it further includes: the temperature sensing element is in contact with the inner wall surface of the installation groove.
[0040] In this technical solution, by directly contacting the temperature sensing element with the installation groove, the temperature sensing element can directly receive heat from the inner wall surface of the installation groove. Since the temperature sensing element is in close contact with the inner wall surface, heat can be transferred from the installation groove to the temperature sensing element more quickly, enabling the temperature sensing element to more timely and accurately sense the temperature change inside the housing body.
[0041] The contact design can reduce the error of temperature measurement. The direct contact between the temperature sensing element and the inner wall surface of the installation groove avoids the influence of factors such as air gaps on heat transfer, thereby enabling more accurate measurement of the temperature inside the installation groove and the housing body.
[0042] In the above technical solution, it further includes: a light-transmitting gel layer, which is provided on the side of the temperature sensing element away from the housing body and covers the temperature sensing element.
[0043] In this technical solution, by providing a light-transmitting gel layer covering the temperature sensing element on the outer side of the temperature sensing element, that is, on the side away from the housing body, on the one hand, it can play a role in physical protection, preventing the temperature sensing element from being damaged by external mechanical damage, chemical corrosion, or other damages, reducing the risk of the temperature sensing element being directly exposed to the environment, and extending the service life of the temperature sensing element. On the other hand, by using the light-transmitting property of the light-transmitting gel layer, light can be evenly transmitted, making the color change of the temperature sensing element more obvious and vivid, enhancing the visual effect, and making it easier for users to observe the temperature change.
[0044] It can be understood that the light-transmitting gel layer can, to a certain extent, prevent moisture from penetrating into the temperature sensing element and the inside of the housing body, improving the waterproof performance of the device.
[0045] This is particularly important for devices used in humid environments or outdoors, helping to protect the device from moisture damage.
[0046] In the above technical solution, the housing body includes a plastic housing body and a metal housing body, and the temperature sensing element is provided on the plastic housing body.
[0047] In this technical solution, the shell body includes two types of material bodies, specifically a plastic body and a metal body. The plastic material has good insulation performance, which can effectively prevent current leakage and improve the safety of the device. The metal material has high strength and hardness, which can provide good mechanical support and protection for the shell body and enhance the overall structural stability of the device.
[0048] Although the thermal conductivity of metal is usually better than that of plastic, the thermal expansion coefficient of plastic is relatively large. By setting the temperature sensing element on the plastic body, the thermal expansion characteristics of plastic can be better utilized, enabling the temperature sensing element to more sensitively perceive temperature changes. When the temperature changes, the degree of expansion or contraction of the plastic body is relatively large, which can more effectively transmit the temperature change to the temperature sensing element, thereby improving the response speed and accuracy of the temperature sensing element.
[0049] By setting the temperature sensing element on the plastic body, it is possible to more accurately sense the temperature change inside the device, provide timely and reliable temperature information for the user, and help avoid device failures or safety problems caused by too high or too low temperatures.
[0050] The second aspect of the present utility model provides an energy storage device, including: any one of the above-mentioned energy storage shells; an energy storage battery disposed inside the energy storage shell.
[0051] According to the technical solution of the energy storage device of the present utility model, the energy storage device includes an energy storage shell and an energy storage battery. The energy storage shell provides physical protection for the internal energy storage battery. The temperature sensing element on the energy storage shell can change color according to the temperature change, enabling the user to intuitively understand the temperature situation of the device, timely discover potential overheating problems, and thus take corresponding measures to protect the safety of the energy storage battery and the entire device.
[0052] By arranging an energy storage battery inside the energy storage shell, the stored electrical energy can be converted into direct current, and the direct current can be converted into alternating current through devices such as an inverter to provide energy for various electrical devices.
[0053] The additional aspects and advantages of the technical solution of the present utility model will become apparent in the following description section or be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] In order to more clearly understand the above-mentioned objects, features and advantages of the embodiments of the present utility model, the embodiments of the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0064] In the following description, many specific details are set forth in order to fully understand the present application. However, the embodiments of the present utility model may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited to the limitations of the specific embodiments disclosed below.
[0065] The following refers to Figures 1 to 6 Describe an energy storage housing and an energy storage device provided according to some embodiments of the present utility model.
[0066] As Figure 1 And Figure 2 As shown, this embodiment provides an energy storage housing 100, including a housing body 102 and a temperature sensing member 104. The color change of the temperature sensing member 104 can indicate the change of the temperature inside the housing. When the temperature reaches a specific threshold, the color of the temperature sensing member 104 will change from the first color to the second color. Through the visual color change, the user can intuitively understand the working state of the device, that is, whether the current temperature is too high, thereby reducing the scald caused by touching, and at the same time reminding the user that the current temperature is too high, and the operation of the inverter 204 may be limited.
[0067] Specifically, a first cavity 1022 is provided inside the housing body 102, which is specifically used to accommodate the inverter 204, ensuring the stability and safety of the inverter 204 during use. Under the action of the housing body 102, the internal components (such as the inverter 204) can be effectively protected from the external environment.
[0068] The first cavity 1022 is enclosed by a partial structure of the housing body 102. By setting the temperature-sensitive element 104 at a position corresponding to the first cavity 1022, the temperature-sensitive element 104 can change color according to the change of the surrounding environment temperature. When the temperature reaches the set threshold, the color change of the temperature-sensitive element 104 can attract the user's attention.
[0069] Among them, the connection between the temperature-sensitive element 104 and the housing body 102 must ensure that it can be exposed to the external environment, so as to facilitate the user to view, and at the same time, it is necessary to ensure that the temperature-sensitive element 104 can sense the temperature change of the first cavity 1022, so as to ensure the accuracy of the color change timing.
[0070] Among them, the temperature-sensitive element 104 can be integrated into a certain part of the housing body 102 to ensure that the side exposed outside the housing is on one side.
[0071] The temperature-sensitive element 104 changes color with temperature. Specifically, the colors that the temperature-sensitive element 104 can change can be only two colors, namely the first color and the second color. Of course, on this basis, the number of color changes can be increased, and even the specific color change process can be a gradual change to meet different use requirements.
[0072] For example, the first color (such as blue) may represent the safe temperature range, while the second color (such as red) represents the warning state of too high temperature.
[0073] The temperature-sensitive element 104 should be set on the outside of the housing body 102 so that the user can see the color change, and at the same time, it should be close to the part that may generate heat (such as the inverter 204) to ensure that it can accurately and timely sense the temperature change.
[0074] This solution can ensure that the temperature-sensitive element 104 can effectively sense the temperature change and provide intuitive temperature information for the user through color change. This design not only improves the safety of the product but also enhances the user experience.
[0075] Optionally, the shell body 102 includes a box body 1032 and a cover plate 1034. By arranging the temperature sensor 104 on the cover plate 1034, the efficiency of temperature sensing and user feedback can be optimized. Among them, under the action of the cover plate 1034, it can play a role in enclosing and protecting the internal inverter 204. By combining the cover plate 1034 with the box body 1032, the overall structure becomes more compact and sturdy, and can effectively prevent external substances (such as dust or liquid) from entering the inside of the box body 1032, protecting the internal electronic components and battery components.
[0076] It should be emphasized that in this solution, by placing the temperature sensor 104 on the cover plate 1034, the specific setting position is near the top of the device or the visible area outside.
[0077] The temperature sensor 104 is arranged on the cover plate 1034. When the internal components (such as the inverter 204) generate heat, the temperature sensor 104 can sense the temperature rise faster. In addition, the temperature sensor 104 is in a position that is easy for users to observe. The color change caused by the temperature change can be directly seen by the user, improving the warning effect and use safety of the device.
[0078] Furthermore, the cover plate 1034 is usually connected to the box body 1032 by hinges, screws or other fixing methods. This connection ensures that the cover plate 1034 can be firmly fixed on the box body 1032, and at the same time allows the cover plate 1034 to be opened when necessary for maintenance or inspection.
[0079] The temperature sensor 104 is installed on the cover plate 1034 by bonding, embedding or other fixing methods. The connection of the temperature sensor 104 must ensure that it closely fits the surface of the cover plate 1034 to ensure that it can effectively conduct and sense temperature changes.
[0080] The first cavity 1022 is located in the part of the box body 1032 close to the cover plate 1034. Such a design makes the distance between the cover plate 1034 and the internal key components (such as the inverter 204) shorter, which helps the rapid conduction of heat and the response of the temperature sensor 104.
[0081] Furthermore, the temperature sensor 104 is located in the obvious area at the center or edge of the cover plate 1034 to ensure that it is easy to observe and not easily blocked.
[0082] Through the newly added cover plate 1034 and the layout of the temperature sensor 104 on the cover plate 1034, the overall design of the energy storage shell 100 has been further optimized in terms of temperature monitoring and user safety prompts. As an important protective part of the shell, the cover plate 1034 not only provides a reliable installation surface, but also improves the efficiency of temperature sensing and the visual warning effect through the combination with the temperature sensor 104.
[0083] In some embodiments, optionally, the temperature sensing member 104 is in powder form, specifically including temperature-sensitive color-changing powder, which can change color according to the change of temperature. By observing the color change of the temperature sensing member 104, the user can intuitively understand the temperature condition of the device. The temperature sensing member 104 and the cover plate are integrally injection-molded, forming an integral structure between the two, enhancing the connection strength and stability between the temperature sensing member 104 and the cover plate.
[0084] Integral injection molding can ensure the sealing performance between the temperature sensing member 104 and the cover plate, prevent dust, moisture, etc. from entering, and protect the internal components.
[0085] In some embodiments, optionally, the temperature sensing member 104 is in powder form, specifically temperature-sensitive color-changing powder. After being mixed with paint, it can be disposed on a part or all of the outer surface of the cover plate 1034 by at least one of spraying and screen printing, so that the cover plate 1034 has the function of changing color with temperature. Specifically, the temperature-sensitive color-changing powder can change color according to the change of temperature. By observing the color change of the temperature sensing member 104, the user can intuitively understand the temperature condition of the device. Spraying or screen printing can evenly coat the temperature-sensitive color-changing powder on the outer surface of the cover plate 1034 to achieve sensitive detection of temperature. The processing methods of spraying or screen printing are relatively flexible and suitable for cover plates 1034 of various shapes and sizes.
[0086] At the same time, through spraying or screen printing, good adhesion is formed between the temperature-sensitive color-changing powder and the surface of the cover plate 1034, ensuring that the temperature sensing member 104 is not easily detached or damaged during use. In addition, the temperature sensing member 104 is precisely applied to a specific area of the cover plate 1034.
[0087] In this embodiment, as Figure 3 shown, the installation groove 106 is provided on the housing body 102, specifically on a part of the housing body 102 that encloses to form the first cavity 1022, and the temperature sensing member 104 is disposed in the installation groove 106. The installation groove 106 enables the temperature sensing member 104 to be stably placed on the housing body 102, preventing the temperature sensing member 104 from being displaced or detached during use. In addition, by installing the temperature sensing member 104 in the installation groove 106, it can be ensured that there is good contact between the temperature sensing member 104 and the housing body 102, so as to more accurately sense the temperature change of the housing body 102. The tight combination of the temperature sensing member 104 and the installation groove 106 enables the temperature sensing member 104 to more quickly respond to the temperature change of the housing body 102, improving the accuracy and timeliness of temperature detection.
[0088] Optionally, the inner wall surface of the installation groove 106, that is, the bottom and the walls of the groove, have good thermal conductivity, and the thermal conductivity is greater than that of the shell body 102. The bottom and / or the walls of the installation groove 106 have better thermal conductivity, which can transfer the heat inside the shell body 102 to the temperature sensing element 104 more quickly, and the temperature sensing element 104 can sense the temperature change more rapidly, improving the timeliness and accuracy of temperature monitoring.
[0089] Due to the better thermal conductivity of the installation groove 106, the temperature sensing element 104 can more acutely sense the minute changes in temperature. This makes the temperature monitoring system more sensitive, capable of issuing a warning at the early stage of abnormal temperature changes, helping users take timely measures to avoid potential problems.
[0090] It can be understood that better thermal conductivity can reduce the influence of the temperature gradient, making the temperature detected by the temperature sensing element 104 more accurately reflect the actual temperature inside the shell body 102.
[0091] Among them, the bottom and / or the walls of the installation groove 106 have high thermal conductivity, which can significantly improve the temperature transfer efficiency and detection sensitivity, playing a positive role in optimizing the reliability, safety and performance of the device.
[0092] Directly contacting the temperature sensing element 104 with the installation groove 106 enables the temperature sensing element 104 to directly receive heat from the inner wall surface of the installation groove 106. Since the temperature sensing element 104 is in close contact with the inner wall surface, heat can be transferred from the installation groove 106 to the temperature sensing element 104 more quickly, enabling the temperature sensing element 104 to more timely and accurately sense the temperature change inside the shell body 102.
[0093] The contact design can reduce the error of temperature measurement. The direct contact between the temperature sensing element 104 and the inner wall surface of the installation groove 106 avoids the influence of factors such as air gaps on heat transfer, thus enabling more accurate measurement of the temperature inside the installation groove 106 and the shell body 102.
[0094] As Figure 5 shown, on the outer side of the temperature sensing element 104, that is, on the side away from the shell body 102, a light-transmitting gel layer 108 covering the temperature sensing element 104 is provided. On the one hand, it can play a role of physical protection, preventing the temperature sensing element 104 from being damaged by the outside world, such as mechanical damage, chemical corrosion or other damages, reducing the risk of the temperature sensing element 104 being directly exposed to the environment, and prolonging the service life of the temperature sensing element 104. On the other hand, by using the light-transmitting property of the light-transmitting gel layer 108, light can be evenly transmitted, making the color change of the temperature sensing element 104 more obvious and vivid, enhancing the visual effect and making it easier for users to observe the temperature change.
[0095] It can be understood that the light-transmitting gel layer 108 can, to a certain extent, prevent moisture from penetrating into the temperature-sensitive component 104 and the inside of the housing body 102, improving the waterproof performance of the device.
[0096] This is particularly important for devices used in humid environments or outdoors, helping to protect the device from moisture damage.
[0097] As Figure 4 shown, the housing body 102 includes two material bodies, specifically a plastic body 1102 and a metal body 1104. The plastic material has good insulation performance, which can effectively prevent current leakage and improve the safety of the device. The metal material has high strength and hardness, which can provide good mechanical support and protection for the housing body 102, enhancing the overall structural stability of the device.
[0098] Although the thermal conductivity of metal is generally better than that of plastic, the thermal expansion coefficient of plastic is relatively large. By arranging the temperature-sensitive component 104 on the plastic body 1102, the thermal expansion characteristics of plastic can be better utilized, enabling the temperature-sensitive component 104 to more sensitively perceive temperature changes. When the temperature changes, the degree of expansion or contraction of the plastic body 1102 is relatively large, which can more effectively transmit the temperature change to the temperature-sensitive component 104, thereby improving the response speed and accuracy of the temperature-sensitive component 104.
[0099] By arranging the temperature-sensitive component 104 on the plastic body 1102, the temperature change inside the device can be more accurately sensed, providing users with timely and reliable temperature information, which helps to avoid device failures or safety issues caused by too high or too low temperatures.
[0100] As Figure 6 shown, the present application provides an embodiment of an energy storage device 200, including an energy storage housing 100 and an energy storage battery 202. The energy storage housing 100 provides physical protection for the internal energy storage battery 202. The temperature-sensitive component on the energy storage housing can change color according to the temperature change, enabling users to intuitively understand the temperature situation of the device, timely discover potential overheating problems, and thus take corresponding measures to protect the safety of the energy storage battery and the entire device.
[0101] By arranging the energy storage battery 202 inside the energy storage housing, the stored electrical energy can be converted into direct current, and the direct current can be converted into alternating current through devices such as an inverter to provide energy for various electrical devices.
[0102] In a specific embodiment, the temperature-sensitive material will produce color changes under the influence of different temperatures and is widely used in fields such as fiber processing, coatings, injection-molded products, and ceramic products. The temperature-sensitive material is added with protective and controlling temperature-sensitive pigments and has three manifestation types: 1. Materials with color at normal temperature become lighter in color until transparent as the temperature rises. 2. Materials without color or transparent at normal temperature show color as the temperature rises. 3. Materials with color at normal temperature become lighter in color until transparent in a specific area through the way of heat generation by external friction.
[0103] This solution adopts two technical solutions: one is the plastic injection molding solution, and the other is the ink and paint solution. In these two solutions, the above two different temperature-sensitive solutions are used to solve the problem of electrical safety when users use balcony energy storage. Solution one is the injection molding solution, and the components included are the top cover. Solution two is the silk screen printing solution of ink and paint, including the text silk screen printing on the surface of the top cover. Both solutions only involve the plastic shell and do not involve solutions of other materials such as sheet metal.
[0104] Solution one: The plastic injection molding solution uses PC as the base material (Note: The base material is suitable for commonly used plastic materials for injection molding, including but not limited to: nylon polyamide (PA), polycarbonate (PC), polyoxymethylene (POM), polypropylene (PE), polystyrene (PS), polyethylene (PE), thermoplastic elastomer (TPU), etc.), and 10% glass fiber is added as the filler (Note: The filler includes but not limited to: carbon fiber (Carbon Fiber), polytetrafluoroethylene (PTFE), clay (Clay), etc.), and functional color-changing microcapsule particles (temperature-sensitive color-changing) are added. The injection molding position is Figure 1 the area pointed by the lead wire of the temperature-sensitive component 104, constituting a position area to alert users of usage safety. Among them, the mass ratio of PC, glass fiber, and temperature-sensitive color-changing powder is 88:10:2.8 - 2. The temperature-sensitive color-changing powder (temperature-changing powder) selected for the plastic injection molding solution is mainly composed of a color-changing dye, a developer, and a solvent. After injection molding, when the product is at normal temperature (25° - 30°), the color-changing dye and the developer are dissolved and dispersed in the solvent, and the particle system presents a white state. When the temperature rises and reaches the solidification temperature of the solvent (40° - 60°), the color-changing dye and the developer approach each other, and under the action of the developer, the structure of the color-changing dye changes, so that the system shows color. By regulating the solidification temperature of the solvent, temperature-changing products that change color at different temperatures can be prepared. The temperature-sensitive color-changing material is affected by the material solvent and the developer and has different color manifestations and color changes at different temperatures. Solution two: The ink and paint solution is to mix the ink by silk screen printing or spraying with the temperature-sensitive color powder. The silk screen printing position is as Figure 2Marked, it plays a role of information reminder on the surface of the energy storage shell. Among them, the mass ratio of the paint to the thermochromic powder is 95:5.1-2. As shown in the following table, at different temperatures, the colors and display degrees presented by screen printing will change to a certain extent.

[0106] The aims of both solutions are to solve the problem that the energy storage battery shell with both household and portable properties generates heat and accidentally injures users. Through the particularity of the material composition, both solutions enable the product to achieve a visual way of quickly and accurately conveying temperature information to users. The specific advantages of this solution are as follows:
[0107] (1) The thermosensitive material adopted in this solution does not need to rely on external forces such as electricity and force, but provides information indication for users by virtue of its chemical composition attributes and sensing temperature changes. In energy storage products that must contain built-in inverters, materials with temperature sensing changes are particularly important to accurately provide perceptible temperature change information without the user's knowledge.
[0108] (2) The colors of the thermosensitive material are relatively rich, and various colors can be displayed under temperature changes, which can also provide customized services for users, enabling users to gain a richer visual experience. At the same time, users can customize the temperature change gradient effect, which meets the consumer-level aesthetic requirements of users and improves the usage experience of energy storage products.
[0109] The thermosensitive capsule material consists of three parts: a discoloring dye, a color developer, and a solvent. Among them, the chemical properties of the solvent will actively protect and release the color-developing components of the material according to temperature changes. As a shell component, the thermosensitive material has a certain protective effect on the outer shell, alleviates the damage of temperature to energy storage products, and delays the aging and weather resistance properties of the products.
[0110] According to the energy storage shell and energy storage device provided by the present invention, through the visual color change, users can intuitively understand the working state of the device, that is, whether the current temperature is too high, thereby reducing scalds caused by touching. At the same time, it also reminds users that the current temperature is too high and the operation of the inverter may be restricted.
