Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to energy storage power supply. Background Technology

[0002] Currently, the international market for portable energy storage products is vast, but the universality of these products faces challenges due to differences in socket specifications across countries.

[0003] Some energy storage products on the market can meet the needs of different socket sizes by selecting different output panel shells. However, these products have the following problems: On the production line, because the output panel shells need to be pre-assembled into semi-finished products, the types and quantities of semi-finished products are difficult to match with the actual shipment requirements; if users replace the output panel shells themselves, due to the large number of mechanical connection structures and wiring harnesses that need to be disassembled and reassembled, the user's hands-on ability is high, and misoperation can easily lead to component damage, and the replacement efficiency is low, making it difficult to cope with emergency scenarios. Utility Model Content

[0004] The purpose of this invention is to provide an energy storage power source to solve the problem of difficulty in replacing sockets of different specifications.

The housing forms an inner cavity to accommodate the energy storage module. The socket is electrically connected to the energy storage module. The housing is provided with a snap-fit ​​hole and a disassembly hole. The side wall of the socket is provided with a spring-loaded latch. The socket is inserted into the snap-fit ​​hole and snapped onto the inner wall of the housing by the spring-loaded latch. The disassembly hole allows a disassembly rod to be inserted to push against the spring-loaded latch, causing the spring-loaded latch to retract and deform, disengage from the housing, and pry out the socket.

[0006] As an optional technical solution, the elastic arm buckle includes an elastic arm, the elastic arm includes a connecting part and a snap-fit ​​part, one end of the connecting part is connected to the socket, the other end of the connecting part is inclined toward the side away from the socket and connected to the snap-fit ​​part, and the inner wall of the housing is provided with a snap-fit ​​rib plate, and the snap-fit ​​part snaps into the snap-fit ​​rib plate.

[0007] As an optional technical solution, the elastic arm buckle also includes a push plate, which is located on the side of the elastic arm away from the socket. The push plate has a first inclined surface, which is inclined towards the side away from the socket along the direction in which the socket is inserted into the snap hole. The disassembly rod can press against the first inclined surface along the direction in which it passes through the disassembly hole, so as to push the elastic arm to retract and deform towards the socket.

[0008] As an optional technical solution, the push plate is further provided with a second inclined surface. The second inclined surface is located on the side of the first inclined surface away from the snap-fit ​​part. Along the direction in which the socket is inserted into the snap-fit ​​hole, the second inclined surface is inclined towards the side closer to the socket. The disassembly rod can press against the second inclined surface to pry one side of the socket outward away from the snap-fit ​​hole.

[0009] As an optional technical solution, the snap-fit ​​plate has an inwardly protruding part, the elastic arm buckle includes at least two spaced elastic arms, the push plate extends along the spacing direction of the elastic arms and connects at least two elastic arms at the same time, and two adjacent elastic arms form a clearance space, which is used to avoid the protruding part.

[0010] As an optional technical solution, the outer wall surface of the snap-fit ​​part is provided with stepped or serrated anti-slip texture.

[0011] As an optional technical solution, the inner ring of the snap-fit ​​hole is provided with a limiting groove, and the outer periphery of the socket is provided with a stop flange. Along the insertion direction of the socket, the end of the stop flange abuts against the bottom of the limiting groove.

[0012] As an optional technical solution, the diameter of the disassembly hole is larger than the outer diameter of the disassembly rod.

[0013] As an optional technical solution, the socket is provided with two spring arm latches, which are symmetrically arranged on the left and right sides of the socket.

[0014] As an optional technical solution, the socket is electrically connected to the energy storage module via a wiring harness, and the socket is provided with a terminal block, which is plugged into the wiring harness.

[0015] The energy storage power supply provided by this utility model has at least the following beneficial effects:

[0016] This energy storage power supply includes a housing, an energy storage module, and a socket. The energy storage module is installed inside the housing. The housing has a snap-fit ​​hole and a disassembly hole. The socket has a spring-loaded latch on its side wall. The socket is inserted into the snap-fit ​​hole and, through the spring-loaded latch, is snapped onto the inner wall of the housing. Through the disassembly hole, a disassembly rod is allowed to penetrate the inner cavity to push against the spring-loaded latch. On one hand, the disassembly rod pushes the spring-loaded latch inward to elastically deform, causing it to detach from the housing and release the snap-fit ​​between the socket and the housing. On the other hand, the disassembly rod continues to push the spring-loaded latch, prying the socket outward through the spring-loaded latch, thus achieving socket disassembly. In summary, the socket of the energy storage power supply provided by this utility model is detachable and replaceable to meet different specification requirements. During installation, pushing the socket into the snap-fit ​​hole automatically snaps it into the housing. During disassembly, inserting the disassembly rod through the disassembly hole and prying the socket out with a push and pry action makes disassembly and assembly very convenient and efficient, significantly improving the user experience.

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figures 1 to 9 As shown, this embodiment provides an energy storage power supply, which includes a housing 1, an energy storage module, and a socket 2. The housing 1 includes a front shell 11 and a rear shell, which are interlocked to form an inner cavity 10. The energy storage module is housed and fixedly installed in the inner cavity 10. An output panel 12 is integrally formed on the side wall of the front shell 11. The socket 2 is installed on the output panel 12 and is electrically connected to the energy storage module to provide power to the user. It can be understood that the energy storage module includes a battery module, an inverter, and a BMS module. The battery module is electrically connected to the BMS module, and the BMS module is electrically connected to the inverter. The socket 2 is specifically electrically connected to the inverter via a wiring harness 4.

[0037] Furthermore, the output panel 12 is provided with a snap-fit ​​hole 101 and a disassembly hole 102. The side wall of the socket 2 is provided with a spring-loaded latch 3. The socket 2 is inserted into the snap-fit ​​hole 101 and is snapped onto the inner wall of the outer casing 1 by the spring-loaded latch 3. The disassembly hole 102 allows the disassembly rod 5 to pass through and push against the spring-loaded latch 3, causing the spring-loaded latch 3 to retract and deform, thus detaching from the outer casing 1 and prying out the socket 2. Specifically, the disassembly rod 5 is a round rod structure, and the disassembly hole 102 is a round hole structure.

[0038] The energy storage power supply provided in this embodiment uses a spring-loaded latch 3 on the side wall of the socket 2 to snap the socket 2 into the inner wall of the outer shell 1. A disassembly hole 102 allows a disassembly rod 5 to penetrate the inner cavity 10 and push against the spring-loaded latch 3. On one hand, the disassembly rod 5 pushes the spring-loaded latch 3 inwards, causing it to elastically deform and detach from the outer shell 1, releasing the latch between the socket 2 and the outer shell 1. On the other hand, the disassembly rod 5 continues to push the spring-loaded latch 3, prying the socket 2 outwards, thus disassembling the socket 2. In summary, the socket 2 of the energy storage power supply provided in this embodiment is detachable and replaceable to meet different specifications. During installation, the socket 2 is automatically snapped into the outer shell 1 by pushing it into the latching hole 101. During disassembly, the disassembly rod 5 is inserted through the disassembly hole 102, and the socket 2 can be pried out by a push and a pry. The disassembly and assembly are very convenient and efficient, significantly improving the user experience.

[0039] Please refer to Figures 2-5The spring-loaded latch 3 includes an elastic arm 31, which includes a connecting part 311 and a locking part 312. One end of the connecting part 311 is connected to the socket 2, and the other end of the connecting part 311 is inclined towards the side away from the socket 2 and connected to the locking part 312. The inner wall of the outer shell 1 is provided with a locking rib plate 103. The locking part 312 is locked into the locking rib plate 103 to prevent the spring-loaded latch 3 and the socket 2 from coming out of the locking hole 101. When the socket 2 is inserted into the locking hole 101, the elastic arm 31 is compressed and deformed inward under the push of the outer end of the hole wall of the locking hole 101. When the elastic arm 31 completely passes through the locking hole 101 and enters the inner cavity 10, the elastic arm 31 elastically returns to its original position and expands outward, automatically locking into the locking rib plate 103.

[0040] Please refer to Figure 5 The outer wall surface of the latching part 312 is provided with stepped or serrated anti-slip textures 3121. The user can press the elastic arm 31 inward through the outer wall surface of the latching part 312. The anti-slip textures 3121 increase friction and prevent the user's fingers from slipping. It can be understood that before the socket 2 is inserted into the latching hole 101, the user can manually press the elastic arm 31 to make the elastic arm buckle 3 retract appropriately, reducing the scratching force of the outer end of the hole wall of the latching hole 101 on the elastic arm 31 and improving durability.

[0041] For example, please refer to Figures 4-7 The spring arm latch 3 also includes a push plate 32, which is located on the side of the elastic arm 31 away from the socket 2. The push plate 32 has a first inclined surface 321. Along the direction in which the socket 2 is inserted into the latching hole 101, the first inclined surface 321 is inclined towards the side away from the socket 2. The disassembly rod 5 can press against the first inclined surface 321 along the direction in which it passes through the disassembly hole 102, so as to push the elastic arm 31 to retract and deform towards the socket 2. Specifically, as the insertion depth of the disassembly rod 5 increases, the contact point between the disassembly rod 5 and the first inclined surface 321 gradually moves inward, thereby pushing the elastic arm 31 to gradually retract inward.

[0042] For example, please refer to Figures 4-9 The push plate 32 is also provided with a second inclined surface 322. The second inclined surface 322 is located on the side of the first inclined surface 321 away from the snap-fit ​​part 312. Along the direction in which the socket 2 is inserted into the snap-fit ​​hole 101, the second inclined surface 322 is inclined towards the side closer to the socket 2. The disassembly rod 5 can press against the second inclined surface 322 to pry one side of the socket 2 outward away from the snap-fit ​​hole 101. Specifically, when the socket 2 is inserted into the snap-fit ​​hole 101, the outer end of the hole wall of the snap-fit ​​hole 101 acts on the second inclined surface 322 to push the entire spring arm buckle 3 inward to deform. In addition, please refer to Figure 9The diameter of the disassembly hole 102 is larger than the outer diameter of the disassembly rod 5. The disassembly rod 5 can be tilted relative to the front shell 11 to change the angle at which it is inserted into the disassembly hole 102, so that it can abut against the second inclined surface 322. By applying pressure to the second inclined surface 322, a component force is formed to push the socket 2 out of the snap-fit ​​hole 101, so as to achieve the purpose of prying one side of the socket 2 outward from the snap-fit ​​hole 101. When one side of the socket 2 is exposed, the user can easily pull out the socket 2, which is very convenient and quick.

[0043] For example, please refer to Figures 2-4 The snap-fit ​​plate 103 has an inwardly protruding protrusion 104. The spring-loaded buckle 3 includes at least two spaced elastic arms 31, with the spacing direction perpendicular to the direction in which the socket 2 is inserted into the snap-fit ​​hole 101. The push plate 32 extends along the spacing direction of the elastic arms 31 and simultaneously connects at least two elastic arms 31. Two adjacent elastic arms 31 form a clearance space 33, which is used to avoid the protrusion 104. The arrangement of multiple elastic arms 31 can achieve multi-point snap-fit, which has high stability. Compared with the design of full-surface deformation, the pushing force required to push its elastic deformation is smaller and easier to operate. The protrusion 104 fills the hollow position and improves the airtightness.

[0044] In this embodiment, the spring arm latch 3 includes two spaced-apart elastic arms 31.

[0045] For example, please refer to Figures 2-9 The inner ring of the snap-fit ​​hole 101 is provided with a limiting groove 105, and the outer periphery of the socket 2 is provided with a stop flange 21. Along the insertion direction of the socket 2, the end of the stop flange 21 abuts against the bottom of the limiting groove 105.

[0046] For example, the socket 2 is provided with two spring arm latches 3, which are symmetrically arranged on the left and right sides of the socket 2 to improve the reliability and stability of the latching structure.

[0047] For example, the spring arm buckle 3 is made of plastic material.

[0048] For example, the elastic arm 31 is integrally formed with the push plate 32.

[0049] For example, the spring arm latch 3 is integrally formed with the housing of the socket 2.

[0050] For example, the wiring harness 4 connecting the socket 2 and the energy storage module has sufficient length slack, allowing the user to pull out the wiring harness 4 when unplugging the socket 2, preventing the wiring harness 4 from being broken. Furthermore, to accommodate the quick-release function of the socket 2, a quick-release mechanical connection is used between the socket 2 and the wiring harness 4. Specifically, the socket 2 is provided with terminals, and the end of the wiring harness 4 is provided with a connector. The connector and the terminals are plugged in to achieve quick connection between the socket 2 and the wiring harness 4. The terminals can specifically be pluggable terminals.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
