Technical Field

[0003] The present application relates to the technical field of energy storage power supplies, and in particular to a housing assembly, an energy storage power supply, and electrical equipment. Background Art

[0004] The housing of an energy storage power supply consists of a front shell and a rear shell, which are connected by screws. This leaves screw holes in the housing, which is unsightly and increases drilling costs. Furthermore, the nuts are typically fixed into the housing through in-mold injection molding, which is a complex process and often results in stress cracking at the nut location, resulting in inconsistent quality.

[0005] Summary of the Invention

[0006] Embodiments of the present application provide a housing assembly, an energy storage power supply, and an electrical device.

[0007] The present application provides an energy storage power supply. The energy storage power supply includes:

[0008] a first housing formed with a plurality of first wedges;

[0009] The second shell is formed with multiple second wedge blocks that cooperate with the first wedge blocks, and each second wedge block is formed with a wedge groove that cooperates with the corresponding first wedge block. When the multiple first wedge blocks are respectively aligned with the multiple wedge grooves and the first shell is pushed along a predetermined direction relative to the second shell, the multiple first wedge blocks can be pushed into the multiple wedge grooves respectively, thereby fixing the first shell on the second shell to form an accommodating space.

[0010] The energy storage power supply of the present embodiment utilizes a first wedge that cooperates with a wedge groove to secure the first and second housings, eliminating the unsightly appearance of screws. This simplifies the process and ensures consistent quality. Furthermore, due to their shape, the first and second wedges are relatively strong, providing a high connection strength that meets mechanical testing requirements, such as weight, for the energy storage power supply.

[0011] The housing assembly according to an embodiment of the present application is applied to an energy storage power supply and includes a third housing and a fourth housing. The third housing is provided with a first connector, which is located within the third housing. The fourth housing is provided with a second connector corresponding to the first connector, which is located within the fourth housing. The first connector and the second connector are pluggable and mated along a first direction to restrict relative movement between the third and fourth housings in directions other than the first direction, and to allow the third and fourth housings to combine to form a housing space.

[0012] The energy storage power supply of the embodiment of the present application includes the housing assembly and the battery assembly described in the above embodiment, and the battery assembly is arranged in the accommodating space.

[0013] The electrical equipment of the embodiment of the present application includes the energy storage power supply described in the above embodiment.

[0014] In the housing assembly, energy storage power supply, and electrical equipment disclosed herein, the third and fourth housings are joined together by plugging and fitting the first and second connectors. This avoids the need for direct screw fastening of the third and fourth housings, reducing installation costs while preventing cracking of the third and / or fourth housings. The plug-and-fitting arrangement of the first and second connectors simplifies installation and facilitates disassembly, facilitating replacement and repair of the energy storage power supply within the housing assembly.

[0045] Referring to Figures 1 to 5, an embodiment of the present application provides an energy storage power supply 100. The energy storage power supply 100 includes a first shell 110 and a second shell 120. The first shell 110 is formed with a plurality of first wedge blocks 112, and the second shell 120 is formed with a plurality of second wedge blocks 121 that cooperate with the first wedge blocks 112. Each second wedge block 121 is formed with a wedge groove 122 that cooperates with the corresponding first wedge block 112. When the plurality of first wedge blocks 112 are respectively aligned with the plurality of wedge grooves 122 and the first shell 110 is pushed in a predetermined direction relative to the second shell 120, the plurality of first wedge blocks 112 can be respectively pushed into the plurality of wedge grooves 122, thereby fixing the first shell 110 on the second shell 120 to form an accommodating space.

[0046] The energy storage power supply 100 of the present embodiment utilizes a first wedge 112 mated with a wedge groove 122 to secure the first housing 110 and the second housing 120, eliminating the use of screws that would otherwise render the housing unsightly. This simplifies the process and ensures consistent quality. Furthermore, due to their shape, the first wedge 112 and the second wedge 121 are relatively strong, providing a high connection strength that meets mechanical testing requirements, such as weight, for the energy storage power supply 100.

[0047] Specifically, in one embodiment, the first housing 110 is a front housing and the second housing 120 is a rear housing, so that the first housing 110 and the second housing 120 can cooperate to form the outer shell of the energy storage power supply 100. In other embodiments, the first housing 110 can also be a rear housing and the second housing 120 can be a front housing, which is not specifically limited here.

[0048] In one embodiment, the first housing 110 may be made of a plastic material with high tensile and compressive strength. This reduces the weight of the energy storage power supply 100 while maintaining its structural strength, thereby saving costs. In one example, the first housing 110 may be made of polypropylene (Acrylonitrile Butadiene Styrene, ABS), or other plastic materials, without specific limitation.

[0049] The second housing 120 is made of the same material as the first housing 110 , so that the energy storage power supply 100 formed by the first housing 110 and the second housing 120 is compact and strong.

[0050] In other embodiments, the first shell 110 and the second shell 120 may also be made of other materials, which are not specifically limited here.

[0051] In one embodiment, the first wedge block 112 may be a wedge-shaped fixed block to enhance the stability of the first wedge block 112. As shown in FIG2 , it can be understood that the first wedge block 112 includes a tip a and a butt b, with the tip a of the first wedge block 112 being closer to the edge of the first housing 110 and the butt b of the first wedge block 112 being further away from the edge of the first housing 110. Viewed from the side, the first wedge block 112 has an inverted triangular shape, which enhances the structural strength of the first wedge block 112 and thus improves the connection stability of the first wedge block 112.

[0052] A plurality of first wedge blocks 112 are formed on the first housing 110 to improve the structural strength of the first housing 110 , thereby improving the stability of the edge of the first housing 110 .

[0053] In one embodiment, the second wedge block 121 is arranged in an L-shape to form a wedge groove 122 with a suitable space. As shown in Figures 2 and 4, it can be understood that the second wedge block 121 is formed by two rectangular fixed blocks arranged substantially perpendicularly to form the wedge groove 122, so as to cooperate with the first wedge block 112 to form a stable structure, thereby tightly combining the first shell 110 and the second shell 120.

[0054] In one embodiment, as shown in Figures 2 and 4 , the length of the wedge groove 122 is substantially the same as the distance from end a to end b of the first wedge block 112, so that the first wedge block 112 matches and engages within the wedge groove 122 to form a stable structure. Furthermore, the width of the wedge groove 122 is smaller than that of the first wedge block 112 to prevent damage to the first wedge block 112 during engagement by the second wedge block 121.

[0055] In one embodiment, as shown in Figures 1 and 3 , the predetermined direction can be understood as the direction in which the first housing 110 is pushed from left to right when the second housing 120 is stationary. Specifically, when the plurality of first wedges 112 are aligned with the plurality of wedge slots 122, the first housing 110 is pushed in the predetermined direction to engage the plurality of first wedges 112 with the plurality of wedge slots 122, thereby securing the first housing 110 and the second housing 120 together to form the outer shell of the energy storage power supply 100 (as shown in Figure 5 ), which is neat and aesthetically pleasing.

[0056] In one embodiment, the first wedge block 112 can also be an integral long strip wedge block, and the second wedge block 121 can also form an integral long strip matching groove corresponding to the wedge block to ensure that the wedge block and the matching groove are integrally engaged, so that the first shell 110 and the second shell 120 are fixed, and the appearance of the energy storage power supply 100 is neat and beautiful.

[0057] Please refer to Figures 6 to 9. In some embodiments, the first shell 110 includes a first top cover 113 and a first bottom plate 114, the first top cover 113 includes a first top cover inner surface 1131, the first bottom plate 114 includes a first bottom plate inner surface 1141, and a plurality of first wedges 112 are formed on the edge of the first top cover inner surface 1131 and / or the edge of the first bottom plate inner surface 1141. The second shell 120 includes a second top cover 123 and a second bottom plate 124, the second top cover 123 includes a second top cover inner surface 1231, the second bottom plate 124 includes a second bottom plate inner surface 1241, and a plurality of second wedges 121 extend from the edge of the second top cover inner surface 1231 and / or the edge of the second bottom plate inner surface 1241.

[0058] In this way, the plurality of first wedge blocks 112 and the plurality of second wedge blocks 121 are cooperatively formed inside the energy storage power supply 100 , making the appearance of the energy storage power supply 100 neat and beautiful.

[0059] Specifically, in one embodiment, the first top cover 113 is disposed on the top of the first shell 110 , and a plurality of first wedge blocks 112 are formed on the edge of the inner surface 1131 of the first top cover.

[0060] 6 , the number of first wedge blocks 112 on the first top cover inner surface 1131 can be five to ensure that the first top cover 113 is tightly coupled with the second top cover 123. In other embodiments, the number of first wedge blocks 112 on the first top cover inner surface 1131 can also be other numbers, which are not specifically limited herein.

[0061] Meanwhile, the second top cover 123 is disposed on the top of the second housing 120 , and a plurality of second wedge blocks 121 extend from the edge of the inner surface 1231 of the second top cover.

[0062] In one example, as shown in FIG8 , the number of second wedge blocks 121 on the second top cover inner surface 1231 can be five to ensure a tight fit between the first top cover 113 and the second top cover 123. In other embodiments, the number of second wedge blocks 121 on the second top cover inner surface 1231 can also be other, and is not specifically limited herein.

[0063] This configuration allows the first wedge 112 on the inner surface 1131 of the first top cover to be combined with the second wedge 121 on the inner surface 1231 of the second top cover, thereby improving the tightness of the combination between the first top cover 113 and the second top cover 123 .

[0064] In one embodiment, the first bottom plate 114 is disposed at the bottom of the first housing 110 , and a plurality of first wedge blocks 112 are formed on edges of an inner surface 1141 of the first bottom plate.

[0065] In one example, as shown in Figure 10, the number of first wedge blocks 112 on the first bottom plate inner surface 1141 can be three to ensure a tight fit between the first bottom plate 114 and the second bottom plate 124. In other embodiments, the number of first wedge blocks 112 on the first bottom plate inner surface 1141 can also be other, and is not specifically limited here.

[0066] Meanwhile, the second bottom plate 124 is disposed at the bottom of the second housing 120 , and a plurality of second wedge blocks 121 extend from the edge of the inner surface 1241 of the second bottom plate.

[0067] 8 , the number of second wedge blocks 121 on the second bottom plate inner surface 1241 can be three to ensure a tight fit between the first bottom plate 114 and the second bottom plate 124. In other embodiments, the number of second wedge blocks 121 on the second bottom plate inner surface 1241 can also be other numbers, which are not specifically limited herein.

[0068] This configuration allows the first wedge block 112 on the inner surface 1141 of the first bottom plate to be combined with the second wedge block 121 on the inner surface 1241 of the second bottom plate, thereby improving the bonding tightness between the first bottom plate 114 and the second bottom plate 124 .

[0069] In summary, the first shell 110 and the second shell 120 respectively connect the first top cover 113 and the second top cover 123 through multiple first wedge blocks 112 and multiple second wedge blocks 121, and connect the first bottom plate 114 and the second bottom plate 124, ensuring that the first shell 110 and the second shell 120 are tightly connected, making the appearance of the energy storage power supply 100 neat and beautiful.

[0070] Please refer to Figure 6. In some embodiments, the first shell 110 includes a first side panel 115 connecting the first top cover 113 and the first bottom panel 114. The first shell 110 includes a plurality of first reinforcing ribs 116 corresponding to the plurality of first wedge blocks 112. The plurality of first reinforcing ribs 116 are formed on the inner surface 1131 of the first top cover and / or the inner surface 1141 of the first bottom panel and respectively connect the corresponding first wedge blocks 112 and the first side panel 115.

[0071] In this way, the structural strength of the first shell 110 is improved, thereby enhancing the structural stability of the energy storage power supply 100.

[0072] Specifically, in one embodiment, a plurality of first reinforcing ribs 116 are formed on the first top cover inner surface 1131 to improve the structural strength of the first top cover 113. In one example, the number of first reinforcing ribs 116 on the first top cover inner surface 1131 can be five, or any other number, which is not specifically limited herein.

[0073] In one embodiment, a plurality of first reinforcing ribs 116 are formed on the first bottom plate inner surface 1141 to improve the structural strength of the first bottom plate 114. In one example, the number of first reinforcing ribs 116 on the first bottom plate inner surface 1141 can be three, or any other number, without specific limitation.

[0074] Multiple first reinforcing ribs 116 respectively connect the corresponding first wedge blocks 112 and the first side panels 115 , which can improve the connection stability between the first side panels 115 and the first bottom panel 114 and the connection stability between the first side panels 115 and the first top cover 113 , thereby improving the structural strength of the first shell 110 .

[0075] In addition, multiple first reinforcing ribs 116 respectively connect the corresponding first wedge block 112 and the first side plate 115, which can also improve the stability of the first wedge block 112, so that the first wedge block 112 is more stably fixed on the inner surface 1131 of the first top cover and / or the inner surface 1141 of the first bottom plate, thereby improving the connection strength between the first wedge block 112 and the second wedge block 121.

[0076] Please refer to Figure 8. In some embodiments, the second shell 120 includes a second side panel 125 connecting the second top cover 123 and the second bottom panel 124. The second shell 120 includes a plurality of second reinforcing ribs 126 corresponding to the plurality of second wedge blocks 121. The plurality of second reinforcing ribs 126 are formed on the inner surface 1231 of the second top cover and / or the inner surface 1241 of the second bottom panel and respectively connect the corresponding second wedge blocks 121 and the second side panel 125.

[0077] In this way, the structural strength of the second shell 120 is improved, thereby enhancing the structural stability of the energy storage power supply 100.

[0078] Specifically, in one embodiment, a plurality of second reinforcing ribs 126 are formed on the second top cover inner surface 1231 to improve the structural strength of the second top cover 123. In one example, the number of second reinforcing ribs 126 on the second top cover inner surface 1231 can be five, or any other number, which is not specifically limited herein.

[0079] In one embodiment, a plurality of second reinforcing ribs 126 are formed on the second bottom plate inner surface 1241 to improve the structural strength of the second bottom plate 124. In one example, the number of second reinforcing ribs 126 on the second bottom plate inner surface 1241 can be three, or any other number, which is not specifically limited herein.

[0080] Multiple second reinforcing ribs 126 respectively connect the corresponding second wedge blocks 121 and the second side panels 125, which can improve the connection stability between the second side panels 125 and the second bottom panel 124, as well as the connection stability between the second side panels 125 and the second top cover 123, thereby improving the structural strength of the second shell 120.

[0081] In addition, multiple second reinforcing ribs 126 respectively connect the corresponding second wedge block 121 and the second side plate 125, which can also improve the stability of the second wedge block 121, so that the second wedge block 121 is more stably fixed on the second top cover inner surface 1231 and / or the second bottom plate inner surface 1241, thereby improving the connection strength between the first wedge block 112 and the second wedge block 121.

[0082] 6 and 7 , in some embodiments, the first wedge block 112 includes a plurality of third reinforcing ribs 1121 , which are substantially perpendicular to the edge of the first top cover inner surface 1131 and / or the edge of the first bottom plate inner surface 1141 .

[0083] In this way, the edge of the first top cover inner surface 1131 and / or the edge of the first bottom plate inner surface 1141 of the first shell 110 is made more secure, thereby improving the stability of the first wedge block 112 .

[0084] Specifically, in one embodiment, the third reinforcing ribs 1121 may be connecting components having the same shape and being parallel to each other, and may be used to improve the firmness of the connection between the first wedge block 112 and the first shell 110 .

[0085] In one embodiment, the number of the third reinforcing ribs 1121 on each first wedge block 112 may be 3, or may be other numbers, which is not specifically limited herein.

[0086] The plurality of third reinforcing ribs 1121 are substantially perpendicular to the edge of the first top cover inner surface 1131 , so as to maximize the bonding strength between the first wedge block 112 and the first top cover inner surface 1131 , thereby improving the stability of the first wedge block 112 on the first top cover inner surface 1131 .

[0087] The plurality of third reinforcing ribs 1121 are substantially perpendicular to the edge of the first bottom plate inner surface 1141 , so as to maximize the bonding strength between the first wedge block 112 and the first bottom plate inner surface 1141 , thereby improving the stability of the first wedge block 112 on the first bottom plate inner surface 1141 .

[0088] In summary, the multiple third reinforcing ribs 1121 are basically perpendicular to the edge of the first top cover inner surface 1131 and / or the edge of the first bottom plate inner surface 1141, ensuring that the bonding strength between the first wedge block 112 and the first shell 110 is maximized, thereby improving the stability of the first wedge block 112 on the first shell 110.

[0089] In some embodiments, the height of each third reinforcing rib 1121 gradually decreases from being away from the edge to being close to the edge.

[0090] In this way, a wedge-shaped structure similar to a triangle is formed, thereby improving the structural strength of the first wedge block 112 .

[0091] Specifically, in one embodiment, the edge may be the edge of the first top cover inner surface 1131 , or the edge of the first bottom plate inner surface 1141 , or an edge corresponding to other embodiments, and no specific limitation is made here.

[0092] In one embodiment, as shown in FIG. 7 , the third reinforcing rib 1121 may be a wedge-shaped structure similar to a triangle, and the wedge-shaped structure includes a tip a and a thick end b, and the wedge-shaped structure gradually becomes sharper from the thick end b toward the tip a.

[0093] The height of each third reinforcement rib 1121 gradually decreases from away from the edge to close to the edge. It can be understood that the tip a is set close to the edge of the first top cover inner surface 1131 and / or the edge of the first bottom plate inner surface 1141, and the thick end b is set away from the edge of the first top cover inner surface 1131 and / or the edge of the first bottom plate inner surface 1141.

[0094] That is, the tip a corresponds to the location where the third reinforcing rib 1121 is at its lowest height, and the butt end b corresponds to the location where the third reinforcing rib 1121 is at its highest height. Furthermore, the height of the third reinforcing rib 1121 gradually decreases from the butt end b toward the tip a, resulting in greater structural strength and stability at the higher end of the third reinforcing rib 1121 (butt end b), thereby improving the structural strength of the first wedge block 112 and ensuring a secure and stable connection between the end of the third reinforcing rib 1121 away from the edge and the second wedge block 121.

[0095] In some embodiments, the first wedge block 112 further includes a connecting rib 1122 , which connects ends of the plurality of third reinforcing ribs 1121 away from the edge.

[0096] In this way, the contact area between the first wedge block 112 and the second wedge block 121 is increased, and the structural strength of the first wedge block 112 is further improved.

[0097] Specifically, in one embodiment, the connecting rib 1122 is arranged at the end of the multiple third reinforcing ribs 1121 away from the edge, and can be used to connect the higher end (thick end b) of the multiple third reinforcing ribs 1121, so that the multiple third reinforcing ribs 1121 and the connecting rib 1122 form a whole, further improving the stability of the first wedge block 112.

[0098] It can be understood that the connecting rib 1122 connects the ends of the multiple third reinforcing ribs 1121 away from the edge, so that the contact area between the first wedge block 112 and the second wedge block 121 is increased to improve the stability of the first wedge block 112 and the second wedge block 121 when they are buckled.

[0099] In some embodiments, an assembly chamfer A is formed between the connecting rib 1122 and the third reinforcing rib 1121 located at the front in the predetermined direction.

[0100] In this way, the sharp portion of the first wedge block 112 is reduced, so that the connection between the connecting rib 1122 and the third reinforcing rib 1121 is smoother, thereby reducing assembly wear and improving assembly efficiency.

[0101] Specifically, in one embodiment, as shown in FIG1 , the predetermined direction may be understood as a direction in which the first shell 110 is pushed from left to right when the second shell 120 is stationary.

[0102] In one embodiment, please refer to Figure 2, the assembly chamfer A can be a rounded shape, so that the connection between the connecting rib 1122 and the third reinforcing rib 1121 at the front in the predetermined direction is smoother, so as to reduce the sharp part of the first wedge block 112, thereby facilitating the sliding engagement of the first wedge block 112 and the second wedge block 121.

[0103] It is worth noting that the second wedge block 121 is formed with a corresponding guide notch B to cooperate with the assembly chamfer A, so that the first shell 110 and the second shell 120 can be assembled smoothly, reducing assembly wear and improving assembly efficiency.

[0104] Please refer to Figure 10. In some embodiments, the first wedge block 112 includes a first mating surface 1123 that cooperates with the second wedge block 121, and the second wedge block 121 includes a second mating surface 1211 that cooperates with the first mating surface 1123. When multiple first wedge blocks 112 are respectively aligned with multiple wedge grooves 122 and push the first shell 110 along a predetermined direction relative to the second shell 120, the first mating surface 1123 slides on the second mating surface 1211 along the predetermined direction so that the first mating surface 1123 abuts against the wedge groove 122, and the distance h from the first mating surface 1123 to the edge of the inner surface 1131 of the first top cover and / or the edge of the inner surface 1141 of the first bottom plate gradually decreases along the predetermined direction.

[0105] In this way, the assembly tolerance space of the first mating surface 1123 is increased to reduce the assembly wear of the first wedge block 112 and the second wedge block 121, thereby improving the assembly efficiency.

[0106] Specifically, as shown in FIG. 10 , in one embodiment, the first mating surface 1123 may be a bevel to increase the assembly tolerance space of the first mating surface 1123 and facilitate the abutment and fixation of the first mating surface 1123 and the second mating surface 1211 .

[0107] It can be understood that the distance h from the first mating surface 1123 to the edge of the first top cover inner surface 1131 and / or the edge of the first bottom plate inner surface 1141 gradually decreases along a predetermined direction, so that the first mating surface 1123 is tilted to facilitate the sliding fit between the first mating surface 1123 and the second mating surface 1211, thereby improving the assembly efficiency of the first wedge block 112 and the second wedge block 121.

[0108] In one embodiment, the second mating surface 1211 is formed with a chamfer, which further reduces the wear generated when the first wedge block 112 and the second wedge block 121 are assembled, thereby improving the assembly efficiency.

[0109] Please refer to Figure 11. In some embodiments, the first wedge block 112 includes a first mating surface 1123 that cooperates with the second wedge block 121, and the second wedge block 121 includes a second mating surface 1211 that cooperates with the first mating surface 1123. When multiple first wedge blocks 112 are respectively aligned with multiple wedge grooves 122 and push the first shell 110 along a predetermined direction relative to the second shell 120, the first mating surface 1123 slides on the second mating surface 1211 along the predetermined direction so that the first mating surface 1123 abuts against the wedge groove 122, and the distance g from the second mating surface 1211 to the edge of the second top cover inner surface 1231 and / or the edge of the second bottom plate inner surface 1241 gradually decreases along the predetermined direction.

[0110] In this way, the assembly tolerance space of the second mating surface 1211 is increased, so as to reduce the assembly wear of the first wedge block 112 and the second wedge block 121 , thereby improving the assembly efficiency.

[0111] Specifically, as shown in FIG. 11 , in one embodiment, the second mating surface 1211 may be a bevel to increase the assembly tolerance space of the second mating surface 1211 and facilitate the abutment and fixation between the first mating surface 1123 and the second mating surface 1211 .

[0112] It can be understood that the distance g from the second mating surface 1211 to the edge of the second top cover inner surface 1231 and / or the edge of the second bottom plate inner surface 1241 gradually decreases along a predetermined direction, so that the second mating surface 1211 is tilted to facilitate the sliding fit between the first mating surface 1123 and the second mating surface 1211, thereby improving the assembly efficiency of the first wedge block 112 and the second wedge block 121.

[0113] It is worth noting that, in one embodiment, the predetermined direction may be the direction in which the first wedge block 112 slides along the second mating surface 1211 of the second wedge block 121 in FIG. 11 .

[0114] In other embodiments, the predetermined direction may also be the direction in which the second wedge block 121 slides along the first mating surface 1123 of the first wedge block 112 , or other sliding directions, which are not specifically limited herein.

[0115] 12 and 13 , in some embodiments, the second mating surface 1211 is formed with a first groove 1212 , and the first mating surface 1123 is formed with a protrusion 1124 corresponding to the first groove 1212 . The first groove 1212 and the protrusion 1124 are fixed to each other.

[0116] In this way, the first wedge block 112 and the second wedge block 121 are tightly engaged and not easily loosened, thereby improving the firmness of the connection between the first shell 110 and the second shell 120.

[0117] Specifically, referring to FIG. 12 and FIG. 13 , in one embodiment, the cross-sectional shape of the protrusion 1124 may be a trapezoid so as to be matched and fixed with the second matching surface 1211 .

[0118] In other embodiments, the protrusion 1124 may also have other cross-sectional shapes, and only needs to be fixed with the second mating surface 1211, and no specific limitation is made here.

[0119] In one embodiment, the cross-sectional shape of the first groove 1212 may be trapezoidal, so that it is tightly engaged with the protrusion 1124 to form an interference fit and is not easy to loosen.

[0120] In other embodiments, the first groove 1212 may also have other cross-sectional shapes, as long as it matches the shape of the protrusion 1124 , and no specific limitation is made here.

[0121] That is, the energy storage power supply 100 is fixed by the first groove 1212 and the protrusion 1124 cooperating with each other, so that the first wedge block 112 and the second wedge block 121 are tightly engaged, thereby improving the connection strength between the first shell 110 and the second shell 120.

[0122] Please refer to Figure 14. In some embodiments, the energy storage power supply 100 also includes a first decorative cover 130, the first shell 110 also includes two oppositely arranged third side panels 117, and the second shell 120 also includes two oppositely arranged fourth side panels 127. The third side panels 117 and the fourth side panels 127 respectively form two notches 31 opposite to each other, and the first decorative cover 130 is fixed to the notches 31 by screws 32.

[0123] In this way, the first shell 110 and the second shell 120 of the energy storage power supply 100 are reinforced, thereby improving the stability of the energy storage power supply 100 .

[0124] Specifically, in one embodiment, the first decorative cover 130 is formed with four screw holes, which can be used to cooperate with the notch 31 to be fixed on the energy storage power supply 100 to ensure that the energy storage power supply 100 is not easy to slide in the left and right directions, thereby further improving the strength of the energy storage power supply 100.

[0125] As can be understood, the first housing 110 and the second housing 120 are pushed and fastened together by the first wedge 112 and the wedge groove 122 to form a stable structure. Furthermore, the first decorative cover 130 is fixed to the energy storage power supply 100 by screws 32, strengthening the connection stability between the first housing 110 and the second housing 120, thereby improving the structural strength of the energy storage power supply 100.

[0126] In one embodiment, the number of the first decorative covers 130 may be 2, or other numbers, which are not specifically limited herein.

[0127] It is worth noting that the first decorative cover 130 is also formed with louvers, which can be used to conduct heat from the inside of the energy storage power supply 100, improve the heat dissipation efficiency of the energy storage power supply 100, and ensure the normal operation of the energy storage power supply 100.

[0128] In some embodiments, the energy storage power supply 100 further includes a handle 140 and a rotating shaft 141 , and the handle 140 is fixed to the energy storage power supply 100 via the rotating shaft 141 .

[0129] In this way, the handle 140 can be rotated and stored, and the energy storage power supply 100 can be conveniently carried.

[0130] Specifically, in one embodiment, the rotating shaft 141 includes a nut, and a thread is formed on the nut of the rotating shaft 141 , which can be used to fix the handle 140 .

[0131] In one embodiment, the handle 140 is formed with a corresponding threaded hole, which can be rotated and fixed with the thread of the shaft 141 to form a whole.

[0132] In one example, the number of the rotating shafts 141 can be two, one for fixing the two ends of the handle 140. In other embodiments, the number of the rotating shafts 141 can also be other, which is not specifically limited here.

[0133] It can be understood that the handle 140 is fixedly matched with the rotating shaft 141, and the rotating shaft 141 is clamped by the first shell 110 and the second shell 120, so that the handle 140 can be rotatably connected to the energy storage power supply 100, which is convenient and flexible.

[0134] In one embodiment, the handle 140 is U-shaped, and the energy storage power supply 100 is formed with a corresponding handle storage groove to facilitate the user to carry and store it.

[0135] In addition, in the related art, an energy storage power supply is a device that uses a power generation device (such as photovoltaics) to generate electricity or directly connect to the mains power network to charge the battery, store electrical energy, and supply power to the outside through the battery when electricity is needed. The outer shell of the energy storage power supply is generally fixed directly with screws. Therefore, screw holes need to be reserved on the outer shell of the energy storage power supply. The setting of the screw holes will affect the overall aesthetics of the energy storage power supply. In addition, the solution of fixing the outer shell with screws requires the opening of screw holes, which will increase the installation cost on the one hand, and on the other hand, the screw holes of the outer shell are also prone to cracking due to stress, affecting the normal use of the energy storage power supply.

[0136] Referring to Figures 15 to 17 , the housing assembly 10 of the present application is applied to an energy storage power supply 100 (shown in Figure 22 ). The housing assembly 10 includes a third housing 11 and a fourth housing 13. The third housing 11 is provided with a first connector 111, which is located inside the third housing 11. The fourth housing 13 is provided with a second connector 131 corresponding to the first connector 111, which is located inside the fourth housing 13. The first connector 111 and the second connector 131 are plugged together along the first direction X to limit the relative movement of the third housing 11 and the fourth housing 13 in directions other than the first direction X, and to combine the third housing 11 and the fourth housing 13 to form an accommodating space 101.

[0137] In the housing assembly 10 of the present application, the third housing 11 and the fourth housing 13 are joined together by plugging and fitting the first connector 111 and the second connector 131. This avoids the need for direct screw connection between the third housing 11 and the fourth housing 13, reducing installation costs while preventing cracking of the third housing 11 and / or the fourth housing 13. The plug-and-fitting arrangement of the first connector 111 and the second connector 131 simplifies installation and facilitates disassembly, facilitating replacement and repair of the energy storage power supply 100 within the housing assembly 10.

[0138] The housing assembly 10 will be further described below with reference to the accompanying drawings.

[0139] Referring to Figures 16 and 17 , in certain embodiments, the housing assembly 10 includes a first wall 1001 and a second wall 1002, which are opposed to each other, and a first surface 1003, a second surface 1004, a third surface 1005, and a fourth surface 1006, respectively connected to the first wall 1001 and the second wall 1002 of the housing assembly 10. The first surface 1003 is opposed to the second surface 1004, and the third surface 1005 is opposed to the fourth surface 1006. With reference to the housing assembly 10, the first direction X can be either the direction from the first surface 1003 toward the second surface 1004 (the opposite direction X2 of the first direction) or the direction from the second surface 1004 toward the first surface 1003 (the positive direction X1 of the first direction). The second direction Y can be either the direction from the third surface 1005 toward the fourth surface 1006 or the direction from the fourth surface 1006 toward the third surface 1005. The third direction Z can be either the direction from the first wall 1001 of the housing assembly 10 to the second wall 1002 of the housing assembly 10, or the direction from the second wall 1002 of the housing assembly 10 to the first wall 1001 of the housing assembly 10. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0140] Specifically, in some embodiments, the third housing 11 and the fourth housing 13 are configured to be docked and joined together. Along a first direction X, the third housing 11 and the fourth housing 13 can collectively form a first surface 1003 and a second surface 1004 of the housing assembly 10. Along a third direction Z, the third housing 11 and the fourth housing 13 can collectively form a first wall 1001 and a second wall 1002 of the housing assembly 10. The third surface 1005 is located on a side of the fourth housing 13 facing away from the third housing 11, and the fourth surface 1006 is located on a side of the third housing 11 facing away from the fourth housing 13. When the third housing 11 and the fourth housing 13 are docked and joined together, they enclose a housing space 101. The housing space 101 within the housing assembly 10 can be used to house other components of the energy storage power supply 100 (shown in FIG. 22 ), such as the battery assembly 20, a control assembly, or a heat dissipation assembly. The other components of the energy storage power supply 100 can be connected to an external power source via the housing assembly 10 to charge the energy storage power supply 100. The other components of the energy storage power supply 100 can also be electrically connected to external electrical appliances via the housing assembly 10 to supply power to the appliances. The housing assembly 10 is made of materials including, but not limited to, insulating materials such as plastic, silicone, or resin to prevent electrical conduction from passing through the housing assembly 10 within the energy storage power supply 100, thereby preventing any danger to the user when using the energy storage power supply 100.

[0141] More specifically, in some embodiments, the third shell 11 includes a first bonding surface 1101 opposite the fourth shell 13, and the fourth shell 13 includes a second bonding surface 1301 opposite the first bonding surface 1101. Along the second direction Y, the first bonding surface 1101 faces away from the fourth surface 1006, and the second bonding surface 1301 faces away from the third surface 1005. When the third shell 11 and the fourth shell 13 are joined, the first bonding surface 1101 and the second bonding surface 1301 can contact each other, thereby tightly connecting the third shell 11 and the fourth shell 13. Therefore, external impurities such as liquids and dust are unlikely to enter the accommodating space 101 through the junction of the third shell 11 and the fourth shell 13, thereby preventing corrosion of components within the shell assembly 10 or affecting heat dissipation of components within the shell assembly 10. In some embodiments, the first and second joining surfaces 1101 and 1301 have the same shape and area, and when the third shell 11 and the fourth shell 13 are assembled, the first and second joining surfaces 1101 and 1301 can completely overlap. In other embodiments, at least one of the shape and area of ​​the first and second joining surfaces 1101 and 1301 is different, and when the third shell 11 and the fourth shell 13 are assembled, the first and second joining surfaces 1101 and 1301 can partially overlap.

[0142] Referring to Figures 16 and 17 , in certain embodiments, the first connector 111 and the second connector 131 are structures that can be plugged into each other along the first direction X. In some embodiments, a portion of the first connector 111 can extend into a portion of the second connector 131. In other embodiments, a portion of the second connector 131 can extend into a portion of the first connector 111. The materials of the first connector 111 and the second connector 131 can be the same or different. For example, the materials of the first connector 111 and / or the second connector 131 include, but are not limited to, metal, plastic, silicone, or resin.

[0143] Further, referring to Figure 18 , in some embodiments, the first connector 111 and the second connector 131 can be plugged and mated along the first direction X. In this case, assuming that the first and second mating surfaces 1101, 1301 have the same shape and area, during the installation of the third housing 11 and the fourth housing 13, the user first moves the third housing 11 or the fourth housing 13 relative to each other along the second direction Y, causing the first mating surface 1101 of the third housing 11 to initially contact but not completely overlap the second mating surface 1301 of the fourth housing 13. At this point, the first and second connectors 111, 131 are both located within the accommodating space 101, and are offset from each other in the first direction X and arranged sequentially along the first direction X. The user then pushes either the third housing 11 or the fourth housing 13 along the first direction X to plug the first connector 111 and the second connector 131. At this point, the first and second mating surfaces 1101, 1301 completely overlap.

[0144] 16 to 18 , in some embodiments, at least two first connectors 111 and at least two second connectors 131 are provided. In some embodiments, along the third direction Z of the housing assembly 10 , the first connectors 111 are provided on opposite sides of the third housing 11 , and the second connectors 131 are provided on opposite sides of the fourth housing 13 .

[0145] Specifically, in some embodiments, the first connector 111 includes a first extension portion 1111 and a first connection portion 1113. The first connection portion 1113 is disposed on the first extension portion 1111 and located on a side of the first extension portion 1111 away from the fourth surface 1006. The first extension portion 1111 is configured to connect the first connection portion 1113 to the inner wall of the third housing 11. The second connector 131 includes a second extension portion 1311 and a second connection portion 1313, which are connected to each other. The second connection portion 1313 is disposed on the second extension portion 1311 and located on a side of the second extension portion 1311 away from the fourth surface 1006. The second extension portion 1311 is configured to connect the second connection portion 1313 to the inner wall of the fourth housing 13, and the second connection portion 1313 is configured to be plugged into and mate with the first connection portion 1113.

[0146] More specifically, along the third direction Z, the first extension portion 1111 is provided on the inner wall of the third housing 11 and extends from the inner wall of the third housing 11 into the accommodating space 101, so that the first connection portion 1113 is closer to the center of the third housing 11 relative to the first coupling surface 1101 in the third direction Z. The second extension portion 1311 is provided on the inner wall of the fourth housing 13 and extends from the inner wall of the fourth housing 13 into the accommodating space 101, so that the second connection portion 1313 is closer to the center of the fourth housing 13 relative to the second coupling surface 1301 in the third direction Z. The first extension portion 1111 and the second extension portion 1311, respectively extending toward the center of the accommodating space 101, ensure that the combined position of the first connection portion 1113 and the second connection portion 1313 is located within the accommodating space 101.

[0147] More specifically, taking the example of the first connector 111 and the second connector 131 being able to plug and mate along the first direction X, in some embodiments, in the first direction X, the first connector 1113 is a protrusion protruding relative to the first extension 1111, and the second connector 1313 is a recessed depression that mates with the protrusion. When the third housing 11 and the fourth housing 13 are assembled, the first connector 1113 extends into the second connector 1313. If the third housing 11 and the fourth housing 13 tend to move in directions other than the first direction X, the outer wall of the first connector 1113 can contact the inner wall of the second connector 1313 to prevent relative movement between the third and fourth housings 11 and 13. In one example, the first connector 1113 extends and protrudes from the first extension 1111 along the positive direction X1 of the first direction X. In this case, the third housing 11 can move relative to the fourth housing 13 along the positive direction X1 of the first direction X, allowing the first connector 1113 to plug and mate with the second connector 1313. In another example, the first connecting portion 1113 extends and protrudes from the first extending portion 1111 in a direction X2 opposite to the first direction X. In this case, the third housing 11 can move relative to the fourth housing 13 in the direction X2 opposite to the first direction X, so that the first connecting portion 1113 and the second connecting portion 1313 can be plugged into each other. In other embodiments, in the first direction X, the second connecting portion 1313 is a protrusion protruding relative to the second extending portion 1311, and the first connecting portion 1113 is a recess that can mate with the protrusion. When the third housing 11 and the fourth housing 13 are assembled, the second connecting portion 1313 extends into the first connecting portion 1113. If the third housing 11 and the fourth housing 13 tend to move in a direction other than the first direction X, the outer wall of the second connecting portion 1313 can contact the inner wall of the first connecting portion 1113 to prevent relative movement between the third housing 11 and the fourth housing 13. In one example, the second connection portion 1313 extends and protrudes from the second extension portion 1311 in the positive direction X1 of the first direction X. In this case, the fourth housing 13 can be moved relative to the third housing 11 in the positive direction X1 of the first direction X to allow the first connection portion 1113 to be plugged into the second connection portion 1313. In another example, the second connection portion 1313 extends and protrudes from the second extension portion 1311 in the opposite direction X2 of the first direction X. In this case, the fourth housing 13 can be moved relative to the third housing 11 in the opposite direction X2 of the first direction X to allow the first connection portion 1113 to be plugged into the second connection portion 1313.

[0148] More specifically, in some embodiments, in the second direction Y, the first connection portion 1113 protrudes relative to the first joint surface 1101, while the second connection portion 1313 does not extend beyond the second joint surface 1301, allowing the first connection portion 1113 to extend into the fourth housing 13 and be plugged into and mated with the second connection portion 1313. In other embodiments, in the second direction Y, the second connection portion 1313 protrudes relative to the second joint surface 1301, while the first connection portion 1113 does not extend beyond the first joint surface 1101, allowing the second connection portion 1313 to extend into the third housing 11 and be plugged into and mated with the first connection portion 1113.

[0149] Furthermore, in some embodiments, the first connector 111 may further include a first reinforcement portion 1115, which is disposed on the first extension portion 1111 and connected to the inner wall of the third housing 11. The first reinforcement portion 1115 is used to support the first connector 1113 and / or the first extension portion 1111, increase the strength of the first connector 111, improve the stability of the connection between the first connector 111 and the third housing 11, and prevent fracture at the connection between the first connector 111 and the third housing 11. The number of first reinforcement portions 1115 can be one, two, or three, etc., and is not limited here.

[0150] Furthermore, in some embodiments, the second connector 131 may further include a second reinforcement portion 1315, which is disposed on the second connector 1313 and connected to the inner wall of the fourth housing 13. The second reinforcement portion 1315 is used to support the second connector 1313 and / or the second extension portion 1311, and to increase the strength of the second connector 131, thereby improving the connection stability between the second connector 131 and the fourth housing 13 and preventing fracture at the connection between the second connector 131 and the fourth housing 13. The number of second reinforcement portions 1315 can be one, two, or three, etc., and is not limited here.

[0151] Referring to Figures 16 to 18 , in certain embodiments, a first mounting portion 1103 may be provided on at least one side of the third housing 11 along the first direction X, and a second mounting portion 1303 may be provided on a side of the fourth housing 13 corresponding to the first mounting portion 1103. Both the first mounting portion 1103 and the second mounting portion 1303 are strip-shaped structures extending along the second direction Y. When the third housing 11 is mounted on the fourth housing 13, one side of the first mounting portion 1103 can abut against one side of the second mounting portion 1303. Along the first direction X, the first mounting portion 1103 and the second mounting portion 1303 are arranged sequentially.

[0152] Furthermore, in some embodiments, the first mounting portion 1103 and the second mounting portion 1303 each include at least two. Along the first direction X of the housing assembly 10 , the first mounting portion 1103 is disposed on two opposite sides of the third housing 11 , and the second mounting portion 1303 is disposed on two opposite sides of the fourth housing 13 .

[0153] In some embodiments, along the first direction X, the second mounting portion 1303 on one side (the right side as shown in FIG18 ) is closer to the center of the accommodating space 101 than the first mounting portion 1103 on the same side, while the second mounting portion 1303 on the other side (the left side as shown in FIG18 ) is further away from the center of the accommodating space 101 than the first mounting portion 1103 on the same side. In other embodiments, the first mounting portions 1103 on both sides are closer to the center of the accommodating space 101 than the second mounting portions 1303 on the same side. In still other embodiments, the first mounting portions 1103 on both sides are further away from the center of the accommodating space 101 than the second mounting portions 1303 on the same side.

[0154] Referring to Figures 18 and 19 , in certain embodiments, the housing assembly 10 may further include a fixing member 15. The fixing member 15 can be used to connect the corresponding first mounting portion 1103 and the second mounting portion 1303. Since the first mounting portion 1103 can abut against the second mounting portion 1303 in the first direction X, after the fixing member 15 connects and fixes the positions of the first mounting portion 1103 and the second mounting portion 1303 along the first direction X, the fixing member 15 can prevent the first mounting portion 1103 from separating from the second mounting portion 1303, thereby limiting the relative movement of the third housing 11 and the fourth housing 13 in all directions. In this application, the fixing member 15 is a screw.

[0155] Referring to Figures 18 and 19 , in certain embodiments, along the first direction X, a first through hole 102 is defined on at least one side of the third housing 11, and a second through hole 103 is defined on a side of the fourth housing 13 corresponding to the first through hole 102. The first through hole 102 and the second through hole 103 together form a mounting opening 104. The mounting opening 104 can be used to observe the interior of the housing assembly 10, allowing for timely repair or component replacement in the event of a malfunction in the energy storage power supply 100 (shown in Figure 22 ). The first mounting portion 1103, the second mounting portion 1303, and the fixing member 15 are opposed to the mounting opening 104, so that the fixing member 15 can be mounted on the first mounting portion 1103 and the second mounting portion 1303 through the mounting opening 104.

[0156] Referring to Figures 19 and 20 , in some embodiments, the housing assembly 10 further includes a second decorative cover 17. The second decorative cover 17 is generally plate-shaped. In some embodiments, only one side of the second decorative cover 17 is rotatably mounted to the third housing 11 and / or the fourth housing 13 along the third direction Z. In other embodiments, both sides of the second decorative cover 17 are rotatably mounted to the third housing 11 and / or the fourth housing 13 along the third direction Z. The second decorative cover 17 is rotatable relative to the third housing 11 and / or the fourth housing 13 to open or cover the mounting opening 104. When the second decorative cover 17 covers the mounting opening 104, it shields the first mounting portion 1103, the second mounting portion 1303, and the fixing member 15, preventing the fixing member 15 from direct contact with the outside, slowing wear of the fixing member 15, and improving the appearance of the housing assembly 10.

[0157] Specifically, in some embodiments, the second decorative cover 17 includes a cover body 171 and a rotating member 173. The cover body 171 is disposed within the mounting opening 104 and serves to cover the mounting opening 104. In some embodiments, the rotating member 173 can be disposed on at least one side of the cover body 171 along the third direction Z. The rotating member 173 can rotate relative to the third housing 11 and the fourth housing 13 about an axis extending along the second direction Y. In this case, the rotating member 173 can be mounted on either the third housing 11 or the fourth housing 13. In one example, the rotating member 173 is disposed on a side of the cover body 171 proximate to the first wall 1001 of the housing assembly 10. In another example, the rotating member 173 is disposed on a side of the cover body 171 proximate to the second wall 1002 of the housing assembly 10. In other embodiments, the rotating member 173 can be disposed on at least one side of the cover body 171 along the second direction Y. The rotating member 173 can rotate relative to the third housing 11 and the fourth housing 13 about an axis extending along the third direction Z. In one example, the rotating member 173 is disposed on a side of the cover 171 close to the third surface 1005 of the housing assembly 10, in which case the rotating member 173 is mounted on the fourth housing 13. In another example, the rotating member 173 is disposed on a side of the cover 171 close to the fourth surface 1006 of the housing assembly 10, in which case the rotating member 173 is mounted on the third housing 11.

[0158] More specifically, the third housing 11 and / or the fourth housing 13 are provided with a limiting groove 105, and the rotating member 173 is rotatably mounted within the limiting groove 105, so that the cover 171 can rotate relative to the third housing 11 and / or the fourth housing 13. When the rotating member 173 is mounted on the third housing 11, the limiting groove 105 is provided in the third housing 11. When the rotating member 173 is mounted on the fourth housing 13, the limiting groove 105 is provided in the fourth housing 13. When there are at least two rotating members 173, at least two limiting grooves 105, and at least two rotating members 173 are provided on the third housing 11 and the fourth housing 13, respectively, at least two limiting grooves 105 are provided on the third housing 11 and the fourth housing 13, respectively.

[0159] More specifically, referring to FIG. 21 , in certain embodiments, the third housing 11 and / or the fourth housing 13 is provided with a first assembly member 106, and the second decorative cover 17 further includes a second assembly member 175. The second assembly member 175 is provided on a side of the cover 171 facing the accommodating space 101. The second assembly member 175 can engage with the first assembly member 106 to maintain the second decorative cover 17 in a position that covers the mounting opening 104. The second assembly member 175 can also disengage from the first assembly member 106 to allow the second decorative cover 17 to open the mounting opening 104.

[0160] More specifically, the number of first assembly members 106 can be one or more, the number of second assembly members 175 corresponds to the number of second assembly members 175, and the position of the first assembly member 106 corresponds to the position of the second assembly member 175. When there is only one second assembly member 175, less material is used for the second assembly member 175, which can save costs. The second assembly member 175 can be located at any position on the side of the cover 171 facing the accommodating space 101. When there are multiple second assembly members 175, the connection between the second decorative cover 17 and the third housing 11 and / or the fourth housing 13 is more stable. The multiple second assembly members 175 can be evenly or unevenly distributed on the side of the cover 171 facing the accommodating space 101.

[0161] In some embodiments, the first assembly part 106 is structured with a connection hole, and the second assembly part 175 is a buckle that can engage with the connection hole. When the second decorative cover 17 covers the mounting opening 104, the second assembly part 175 can extend into the connection hole of the first assembly part 106. When the second decorative cover 17 opens the mounting opening 104, the second assembly part 175 can be removed from the connection hole of the first assembly part 106. In other embodiments, the second assembly part 175 is structured with a connection hole, and the first assembly part 106 is a buckle that can engage with the connection hole. When the second decorative cover 17 covers the mounting opening 104, the first assembly part 106 can extend into the connection hole of the second assembly part 175. When the second decorative cover 17 opens the mounting opening 104, the first assembly part 106 can be removed from the connection hole of the second assembly part 175.

[0162] Referring to Figures 19 and 20 , in certain embodiments, along the third direction Z, when the rotating member 173 can be disposed on at least one side of the cover 171, a second groove 107 is defined on a side of the third housing 11 and / or the fourth housing 13 opposite the rotating member 173. The second groove 107 is located outside of and communicates with the mounting opening 104, with one side of the second decorative cover 17 located at the opening of the second groove 107. To open the second decorative cover 17, the user can contact the side of the second decorative cover 17 through the second groove 107 and apply force to the second decorative cover 17, thereby separating the second decorative cover 17 from the third housing 11 and the fourth housing 13.
