[0042] Figures 1 to 9A unified spatial rectangular coordinate system is adopted to represent the relative position relationship between the electrical component 100 and the housing component 200 of the energy storage power supply. Among them, the X-axis direction is the first direction, the Y-axis direction is the second direction, and the Z-axis direction is the third direction. Exemplarily, the X-axis direction is the length direction of the energy storage power supply, the Y-axis direction is the height direction of the energy storage power supply, and the Z-axis direction is the width direction of the energy storage power supply.

[0043] Referring to Figure 1 , Figure 2 and Figure 6 shown, the energy storage power supply involved in the embodiment of the present invention includes: an electrical component 100 and a housing component 200.

[0044] Specifically, the electrical component 100 includes an inverter circuit board 110 and one or more circuit boards 120; the housing component 200 includes a first housing 210, a second housing 220, and a third housing 230. The first housing 210 and the second housing 220 are detachably connected to define a receiving cavity 240. Part or all of the electrical component 100 is disposed in the receiving cavity 240. At least one circuit board 120 is disposed on the third housing 230. The first housing 210 is provided with a first opening 211. The first opening 211 communicates with the receiving cavity 240. The first opening 211 is located at one end of the receiving cavity 240 along the first direction. The third housing 230 is detachably disposed at the first opening 211, so that the receiving cavity 240 is a closed space. Exemplarily, part or all of the third housing 230 is within the first opening 211, and the first housing 210 and the second housing 220 are connected to limit the displacement of the third housing 230. The first opening 211 may be a U-shaped opening, and the U-shaped opening faces the second housing 220 in the second direction, or may be an opening with a closed perimeter. Exemplarily, the third housing 230 covers the first opening 211, that is, covers the first housing 210 and the second housing 220. The covering connection method may be that the third housing 230 houses the first housing 210 and the second housing 220, or the edge of the third housing 230 covers the edges of the first housing 210 and the second housing 220.

[0045] When the third housing 230 covers the first housing 210 and the second housing 220, when it is necessary to replace or maintain the electrical component 100, the third housing 230 can be removed from the first opening 211, and then the second housing 220 is separated from the first housing 210, so that part of the electrical component 100 is exposed at the first opening 211. Therefore, part of the electrical component 100 can be maintained through the third housing 230 and the first opening 211. At the same time, since the first opening 211 is located at one end of the receiving cavity 240 along the first direction, when it is necessary to take out the electrical component 100 from the receiving cavity 240 for replacement, the first opening 211 can increase the operating space to facilitate taking out the electrical component 100 from the receiving space.

[0046] Specifically, in the above embodiments, the circuit board 120 is used for direct current power supply, including but not limited to a cigarette lighter circuit board 120 (not shown), an LED lamp or other lamp circuit board 120 (not shown), a USB or type-C circuit board 120 (not shown), a digital display or liquid crystal display circuit board 120 (not shown), etc.

[0047] Refer to Figure 2 and Figure 3 As shown, the first housing 210 includes a first sub-first housing 213, a second sub-first housing 214, and a third sub-first housing 215. The third sub-first housing 215 is disposed opposite to the second housing 220 in the second direction. The first sub-first housing 213 and the second sub-first housing 214 are disposed opposite to each other in the third direction and form a first opening 211 and / or a second opening 212. The first sub-first housing 213 and the second sub-first housing are disposed between the third sub-first housing 215 and the second housing 220.

[0048] Specifically, in the above embodiments, the first sub-first housing 213 is detachably connected to the third sub-first housing 215, and the second sub-first housing 214 is detachably connected to the third sub-first housing 215.

[0049] It can be understood that the first housing 210 includes a first sub-first housing 213, a second sub-first housing 214, and a third sub-first housing 215, that is, the first housing 210 can be split into three parts. When manufacturing the first housing 210, the first housing 210 can be split into three parts for production, improving the production efficiency of the first housing 210.

[0050] Continue to refer to Figure 2 As shown, the periphery of the first opening 211 is closed.

[0051] Specifically, in the above embodiments, the periphery of the second opening 212 is closed.

[0052] It can be understood that since the periphery of the first opening 211 is closed, when the third housing 230 is connected to the first opening 211, the edge of the first opening 211 and the third housing 230 can have a larger connection contact area, thereby improving the connection stability between the edge of the third housing 230 and the first opening 211, and thus improving the connection stability between the third housing 230 and the first housing 210. Similarly, since the periphery of the second opening 212 is closed, when the fourth housing 250 is connected to the second opening 212, the edge of the second opening 212 and the fourth housing 250 can have a larger connection contact area, thereby improving the connection stability between the edge of the fourth housing 250 and the second opening 212, and thus improving the connection stability between the fourth housing 250 and the first housing 210.

[0053] Continue to refer to Figure 3 As shown, the first sub-first housing 213 has a first sub-first opening 2131 and a first sub-second opening 2132, and the second sub-first housing 214 has a second sub-first opening 2141 and a second sub-second opening 2142. The first sub-first opening 2131 faces the second sub-first opening 2141 and forms a first opening 211 with the second sub-first opening 2141. The first sub-second opening 2132 faces the second sub-second opening 2142 and forms a second opening 212 with the second sub-second opening 2142.

[0054] Specifically, in the above embodiment, the first sub-first opening 2131, the first sub-second opening 2132, the second sub-first opening 2141, and the second sub-second opening 2142 are all U-shaped openings. The U-shaped openings face the third direction. The edge of the first sub-first opening 2131 is detachably connected to the edge of the second sub-first opening 2141 to close the periphery of the first opening 211. The edge of the first sub-second opening 2132 is detachably connected to the edge of the second sub-second opening 2142 to close the periphery of the second opening 212.

[0055] More specifically, in the above embodiment, the edge of the first sub-first opening 2131 is detachably connected to the edge of the second sub-first opening 2141 by a buckle, and the edge of the first sub-second opening 2132 is detachably connected to the edge of the second sub-second opening 2142 by a buckle.

[0056] Exemplarily, the third housing 230 is slidably connected to the first sub-first opening 2131 or the second sub-first opening 2141. The first opening 211 is formed by the first sub-first opening 2131 and the second sub-first opening 2141 to limit the displacement of the third housing 230. The specific manner of this sliding connection is that both the first sub-first opening 2131 and the second sub-first opening 2141 have concave receiving grooves (not shown), and the third housing 230 has a protrusion (not shown) that matches the concave receiving groove. The protrusion can slide to a predetermined position within the first sub-first opening 2131 or the second sub-first opening 2141. Similarly, the fourth housing 250 is slidably connected to the first sub-second opening 2132 or the second sub-second opening 2142. The second opening 212 is formed by the first sub-second opening 2132 and the second sub-second opening 2142 to limit the displacement of the fourth housing 250. The specific manner of this sliding connection is that both the first sub-second opening 2132 and the second sub-second opening 2142 have concave receiving grooves (not shown), and the fourth housing 250 has a protrusion (not shown) that matches the concave receiving groove. The protrusion can slide to a predetermined position within the first sub-second opening 2132 or the second sub-second opening 2142.

[0057] Exemplarily, the third housing 230 covers the first opening 211, that is, it covers the first sub-first opening 2131 and the second sub-first opening 2141. When the third housing 230 is connected to the first housing 210, it can make the third housing 230 connected to the edges of the first sub-first opening 2131 and the second sub-first opening 2141, enabling the edge of the first opening 211 to have a larger connection contact area with the third housing 230, thereby improving the connection stability between the third housing 230 and the edge of the first opening 211, and thus improving the connection stability between the third housing 230 and the first housing 210. Similarly, the second opening 212 can be formed by the first sub-second opening 2132 and the second sub-second opening 2142. When the fourth housing 250 is connected to the first housing 210, it can make the fourth housing 250 connected to the edges of the first sub-second opening 2132 and the second sub-second opening 2142, enabling the edge of the second opening 212 to have a larger connection contact area with the fourth housing 250, thereby improving the connection stability between the fourth housing 250 and the edge of the second opening 212, and thus improving the connection stability between the fourth housing 250 and the first housing 210.

[0058] Referring Figure 4 As shown, the first housing 210 includes a fourth sub-first housing 216 and a fifth sub-first housing 217. The fourth sub-first housing 216 is provided with a first mounting groove 2133 and a first opening 211 on one side in the first direction. The fifth sub-first housing 217 is detachably disposed in the first mounting groove 2133. At least one of a cigarette lighter circuit board 120 (not shown), an LED lamp or other lamp circuit board 120 (not shown), a USB or type-C circuit board 120 (not shown), a digital display or a liquid crystal display circuit board 120 (not shown), etc. can be disposed on the fifth sub-first housing 217.

[0059] It can be understood that the circuit board 120 on the fifth sub-first housing 217 is used to connect to an external device to charge the energy storage power supply or supply power or charge the external device. Removing the fifth sub-first housing 217 from the first mounting groove 2133 can expose the electrical component 100 at the first mounting groove 2133. Therefore, the electrical component 100 can be maintained through the first mounting groove 2133. At the same time, when it is necessary to take out and replace the electrical component 100 from the accommodation cavity 240, the first mounting groove 2133 can further provide an operating space for the electrical component 100 to facilitate taking out the electrical component 100 from the accommodation space.

[0060] Referring Figure 6 and Figure 7As shown, the housing assembly 200 further includes a fourth housing 250. The first housing 210 is provided with a second opening 212 which communicates with the accommodation cavity 240. The second opening 212 is located at the other end of the accommodation cavity 240 along the first direction. The fourth housing 250 is detachably disposed at the second opening 212. Exemplarily, the fourth housing 250 is slidably connected to the first opening 211, and the first housing 210 is connected to the second housing 220 to limit the displacement of the third housing 230. Exemplarily, the third housing 230 covers the first opening 211, that is, covers the first housing 210 and the second housing 220. The covering connection manner may be that the third housing 230 houses the first housing 210 and the second housing 220, or the first housing 210 and the second housing 220 house the third housing 230.

[0061] In the case where the third housing 230 and the fourth housing 250 respectively cover the first housing 210 and the second housing 220, when it is necessary to replace or maintain the electrical component 100, the third housing 230 can be removed from the first opening 211, the fourth housing 250 can be removed from the second opening 212, and then the second housing 220 can be separated from the first housing 210, so that the electronic component is exposed at the first opening 211 and the second opening 212, and at the same time, the electronic component is also exposed at the connection between the first housing 210 and the second housing 220. Therefore, an operating space can be added for the electrical component 100 through the first opening 211, the second opening 212 and the connection between the first housing 210 and the second housing 220, so as to facilitate the maintenance of the electrical component 100. At the same time, since the first opening 211 and the second opening 212 are respectively located at both ends of the accommodation cavity 240 along the first direction, when it is necessary to take out and replace the electrical component 100 from the accommodation cavity 240, the first opening 211 and the second opening 212 can provide operating spaces at both ends of the electrical component 100 along the first direction, so as to facilitate taking out the electrical component 100 from the accommodation space. Thus, the above energy storage power supply can facilitate the maintenance or replacement of the electrical component 100 inside the energy storage power supply.

[0062] Refer to Figure 6 As shown, the first housing 210 is further provided with a third opening 218. The first opening 211 and the second opening 212 both communicate with the third opening 218. The second housing 220 is detachably disposed at the third opening 218.

[0063] It can be understood that since the second housing 220 is detachably disposed at the third opening 218, when the second housing 220 is removed from the third opening 218, the electrical component 100 can be maintained. At the same time, when the electrical component 100 needs to be taken out from the accommodation cavity 240 for replacement, the third opening 218 can further provide an operating space for the electrical component 100 to facilitate taking out the electrical component 100 from the accommodation space.

[0064] Referring to Figure 8 As shown, the third opening 218 divides the accommodation cavity 240 into a first cavity 241 and a second cavity 242. Exemplarily, the electrical component 100 can be located in the first cavity 241 and the second cavity 242, or can be located in the first cavity 241.

[0065] Specifically, in the above embodiment, the first cavity 241 is disposed in the first housing 210, and the second cavity 242 is disposed in the second housing 220.

[0066] It can be understood that when the electrical component 100 is located in the first cavity 241 and the second cavity 242, that is, a part of the electrical component 100 is located in the first cavity 241 and another part of the electrical component 100 is located in the second cavity 242, removing the second housing 220 from the first housing 210 can maintain the electrical component 100. At the same time, when the electrical component 100 needs to be taken out from the accommodation cavity 240 for replacement, the third opening 218 can further provide an operating space for the electrical component 100 to facilitate taking out the electrical component 100 from the accommodation space.

[0067] Referring to Figures 2 to 5 As shown, the first housing 210 has a first connection portion 219 facing the second housing 220, and the second housing 220 has a second connection portion 221. The first connection portion 219 and the second connection portion 221 are detachably connected.

[0068] Specifically, in the above embodiment, the first connection portion 219 is disposed on the cavity wall of the first cavity 241 away from the third opening 218, and the second connection portion 221 is disposed on the cavity wall of the second cavity 242 away from the third opening 218, which can make the first connection portion 219 and the second connection portion 221 respectively located on the cavity walls at both ends of the accommodation cavity 240, so as to have a more stable connection relationship between the first housing 210 and the second housing 220, thereby increasing the structural stability of the above energy storage power supply.

[0069] It can be understood that the detachable connection between the first housing 210 and the second housing 220 can be realized through the first connection portion 219 and the second connection portion 221.

[0070] Further, in addition to this, in other embodiments, the first housing 210 and the second housing 220 may also be snap-connected through a snap structure or slidably connected through a chute structure.

[0071] Continue to refer to Figure 2 、 Figure 5 and Figure 9 As shown, the second connecting portion 221 is provided with a second installation groove 2211, and a part of the first connecting portion 219 is received in the second installation groove 2211.

[0072] Specifically, in the above embodiment, the second installation groove 2211 is opened toward the first housing 210.
