Description

Technical Field

[0001] This utility model relates to the field of energy storage device technology, and more specifically, to a portable energy storage device. Background Technology

[0002] An energy storage device is a device or system that stores energy through specific technologies and releases it when needed. Its core function is to solve the problem of mismatch between energy supply and demand in terms of time, space, or form, and to achieve efficient energy utilization and flexible scheduling.

[0003] To meet users' needs for portability and flexibility of energy storage devices, related technologies include an arched handle on the top of the energy storage device for users to lift or carry it.

[0004] This design requires the energy storage device to have a separate handle, and it has many components and a complex structure. Utility Model Content

[0005] In order to solve or improve the technical problems of energy storage devices in related technologies that require separate handles, have many parts and complex structures, the purpose of this utility model is to provide a portable energy storage device.

[0006] To achieve the above objectives, this utility model provides a portable energy storage device, comprising: a main unit; at least two first fixing members disposed on the main unit; a handle structure formed by folding a charging cable in half, the handle structure having a first mounting area and a second mounting area, the first mounting area being connected to the main unit through at least one first fixing member, and the second mounting area being connected to the main unit through at least one first fixing member; wherein, the handle structure includes two branch wire harnesses and a bent portion for connecting the two branch wire harnesses, each branch wire harness having a metal connector at the end away from the bent portion; the first mounting area and the second mounting area are both disposed on the branch wire harnesses, the first mounting area being closer to the metal connector, and the second mounting area being closer to the bent portion.

[0007] This utility model aims to provide a portable energy storage device that uses a folded charging cable as a handle. This design has two advantages: first, it makes full use of the existing components in the portable energy storage device, eliminating the need for a separate handle, which helps reduce the number of components, simplify the structure, and make the overall structure more compact; second, it achieves portability, making it easy to carry even in outdoor environments, which helps improve the user experience.

[0008] It should be noted that the two installation areas of the handle structure are not necessarily at the two ends of the handle structure. This design allows for adjustment of the connection position between the handle structure and the first fixing component, as well as the usable length of the handle structure, according to actual needs, thus offering greater flexibility.

[0009] In some technical solutions, the portable energy storage device may optionally include: a wiring harness constraint, disposed on the handle structure; wherein, branch wiring harnesses pass through the wiring harness constraint, and the wiring harness constraint is used to limit the movement of the two branch wiring harnesses.

[0010] In this technical solution, by setting a wire harness constraint, the two branch wire harnesses formed after the charging cable is folded in half can be limited to prevent misalignment between the two branch wire harnesses, thus affecting the installation of the handle structure. The wire harness constraint can make the folded charging cable more regular, so that the folded charging cable can be used as the handle structure.

[0011] In some technical solutions, optionally, the wire harness constraint is located in the first installation area, and the wire harness constraint is detachably connected to the first fixing member.

[0012] In this technical solution, since the wiring harness constraint and the first fixing component are detachably connected, the connection between the handle structure and the main unit is also detachable. This design facilitates the assembly and disassembly of the handle structure. When the portable energy storage device needs to be moved, the charging cable can be folded in half to serve as the handle structure; when the portable energy storage device needs to be used as an emergency power source, the handle structure can be removed.

[0013] In some technical solutions, optionally, the wire harness constraint is a snap-fit ​​structure with two constraint channels, each branch wire harness being independently threaded through a corresponding constraint channel; the snap-fit ​​structure also has a first limiting hole, and the first fixing member has a second limiting hole; the portable energy storage device further includes: a first connector, which is threaded through the first limiting hole and the second limiting hole to achieve a detachable connection between the wire harness constraint and the first fixing member.

[0014] In this technical solution, the buckle structure has two functions: first, to limit the two branch wire harnesses; second, to detachably connect with the first fixing member to achieve a detachable connection between the handle structure and the main unit.

[0015] In some technical solutions, optionally, the wire harness constraint member is a constraint band, which forms a ring structure, and the branch wire harness passes through the ring structure; the constraint band and the first fixing member are detachably connected.

[0016] In this technical solution, the constraint strap has two functions: first, to limit the movement of the two branch wire harnesses; second, to detachably connect with the first fixing member to achieve a detachable connection between the handle structure and the main unit.

[0017] In some technical solutions, optionally, the wire harness constraint includes a limiting groove, within which the branch wire harness is disposed. A latch is provided at the opening of the limiting groove, used to open or close the opening of the limiting groove.

[0018] In this technical solution, when the handle structure needs to be disassembled or assembled, the connection between the wire harness constraint and the first fixing component does not need to be considered. The slot of the limiting groove can be opened or closed directly to allow the branch wire harness to be placed or removed. This design method is simple in structure and more convenient to operate.

[0019] In some technical solutions, the first fixing member may optionally include: a first part connected to the main unit, the first part having a mounting groove for accommodating the branch wire harness of the handle structure; and a second part rotatably connected to the first part to open or close the mounting groove.

[0020] In this technical solution, when the portable energy storage device needs to be moved, the branch harness is placed in the mounting slot, and the mounting slot is closed by rotating the second part. At this time, the handle structure is connected to the main unit. When the portable energy storage device needs to be used as an emergency power source, the mounting slot can be opened directly by rotating the second part, and the branch harness can be taken out. In this design, the branch harness of the handle structure is directly connected to the first fixing component, which is simple in structure and more convenient to operate.

[0021] In some technical solutions, optionally, the host has a first side and a second side opposite to each other; at least one first fastener is disposed on the first side, and the first mounting area is connected to the first side through at least one first fastener; at least one first fastener is disposed on the second side, and the second mounting area is connected to the second side through at least one first fastener.

[0022] In this technical solution, the first fixing component is symmetrically distributed on both sides of the main unit. When the folded charging cable is used as a handle structure, the pulling force is evenly transmitted to both sides of the main unit through the first mounting area and the second mounting area, avoiding deformation of the main unit or detachment of the first fixing component caused by unilateral force.

[0023] In some technical solutions, optionally, the wire harness constraint is also provided in the second installation area, and the wire harness constraint is detachably connected to the first fixing member.

[0024] In this technical solution, since the wiring harness constraint and the first fixing component are detachably connected, the connection between the handle structure and the main unit is also detachable. This design facilitates the assembly and disassembly of the handle structure. When the portable energy storage device needs to be moved, the charging cable can be folded in half to serve as the handle structure; when the portable energy storage device needs to be used as an emergency power source, the handle structure can be removed.

[0025] In some technical solutions, the host computer may optionally have at least one charging interface and at least one power supply interface.

[0026] In this technical solution, by setting up a charging interface and a power supply interface, when the power is insufficient, the user can replenish the battery pack of the host through the charging interface; when there is a power demand, the user can supply power to the electrical equipment through the power supply interface to meet the needs of temporary or emergency power use.

Detailed Implementation

[0042] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, embodiments of the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] An energy storage device is a device or system that stores energy through specific technologies and releases it when needed. Its core function is to solve the problem of mismatch between energy supply and demand in terms of time, space, or form, and to achieve efficient energy utilization and flexible scheduling.

[0045] In one specific embodiment, the energy storage device is an electrical energy storage device that stores electrical energy through specific technical means and releases the electrical energy when needed.

[0046] As users increasingly demand portability and flexibility from energy storage devices, portable energy storage devices are becoming more and more widely used. Portable energy storage devices are typically equipped with multiple power supply interfaces, such as USB (Universal Serial Bus), AC (Alternating Current), and DC (Direct Current) interfaces, to meet the power needs of various devices such as mobile phones, laptops, outdoor lights, small home appliances, and drones.

[0047] In related technologies, portable energy storage devices require a separately designed arched handle, which involves many components and has a complex structure.

[0048] This utility model aims to provide a portable energy storage device that uses a folded charging cable as a handle. This design has two advantages: first, it makes full use of the existing components in the portable energy storage device, eliminating the need for a separate handle, which helps reduce the number of components, simplify the structure, and make the overall structure more compact; second, it achieves portability, making it easy to carry even in outdoor environments, which helps improve the user experience.

[0049] The following reference Figures 1 to 12 This invention describes a portable energy storage device provided according to some embodiments of the present invention.

[0050] In one embodiment of this utility model, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the portable energy storage device 1 includes a main unit 10, at least two first fixing members 12, and a handle structure 14.

[0051] At least two first fixing members 12 are provided on the main unit 10. The handle structure 14 is formed by folding the charging cable 16 in half. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the handle structure 14 has a first mounting area 142 and a second mounting area 144. The first mounting area 142 is connected to the main unit 10 through at least one first fastener 12, and the second mounting area 144 is connected to the main unit 10 through at least one first fastener 12.

[0052] The handle structure 14 includes two branch wire harnesses 162 and a bend 164 for connecting the two branch wire harnesses 162. Each branch wire harness 162 has a metal connector 166 at the end away from the bend 164. A first mounting area 142 and a second mounting area 144 are both located on the branch wire harnesses 162, with the first mounting area 142 closer to the metal connector 166 and the second mounting area 144 closer to the bend 164.

[0053] Portable energy storage device 1 refers to an energy storage device or apparatus that is miniaturized, lightweight, and portable, and can provide convenient power supply for outdoor, emergency, and other scenarios. Its core design goal is to meet users' needs for portability and flexibility while ensuring a certain energy capacity and output power.

[0054] The host 10 can be understood as the energy storage device body or the main body of the energy storage device, which is used to store electrical energy and supply power to some electrical equipment when needed by users to meet their electricity needs.

[0055] The number of first fasteners 12 is at least one, that is, the first fasteners 12 can be one, two or more, and the number, position and type of the first fasteners 12 can be flexibly set according to actual needs.

[0056] The first fastener 12 is used to secure the folded charging cable 16 so that the folded charging cable 16 serves as the handle structure 14 of the portable energy storage device 1.

[0057] It should be noted that the charging cable 16 is an existing component of the portable energy storage device 1. By using the folded charging cable 16 as the handle structure 14, there is no need to set up a separate handle, which helps to reduce the number of components, simplify the structure, and make the overall structure more compact.

[0058] The charging cable 16 has a metal connector 166 at each end. When the charging cable 16 is folded in half, it has two branch wire bundles 162, and the two branch wire bundles 162 are connected by a bend. The metal connector 166 is located at the end of the branch wire bundle 162 away from the bend.

[0059] The first installation area 142 and the second installation area 144 can be the charging cable 16 itself (e.g., a certain position of the branch harness 162), or other components (e.g., harness constraint 18) set on the charging cable 16.

[0060] This utility model aims to provide a portable energy storage device 1, in which the folded charging cable 16 is used as the handle structure 14. This design has two advantages: first, it makes full use of the original components in the portable energy storage device 1, eliminating the need for a separate handle, which helps to reduce the number of components, simplify the structure, and make the overall structure more compact; second, it achieves portability, making it easy to carry even in outdoor environments, which helps to improve the user experience.

[0061] It should be noted that the two installation areas of the handle structure 14 are not necessarily the two ends of the handle structure 14. This design allows for adjustment of the connection position between the handle structure 14 and the first fixing member 12, as well as the length of the handle structure 14, according to actual needs, thus providing greater flexibility.

[0062] In some embodiments, the host 10 may optionally include a battery pack and a BMS (Battery Management System) module. The BMS module is electrically connected to the battery pack.

[0063] The BMS module is the core control module of the portable energy storage device 1. The BMS module undertakes key functions such as monitoring, protecting, charging and discharging management and status assessment of the battery pack.

[0064] In some embodiments, the handle structure 14 may optionally include a first end region and a second end region disposed opposite to each other. The first end region includes two metal connectors 166 of the charging cable 16, and the second end region includes a bend 164 formed by folding the charging cable 16 in half.

[0065] In the first mounting region 142 and the second mounting region 144, the first mounting region 142 is closer to the first end region in the first end region and the second end region in the second end region, and the second mounting region 144 is closer to the second end region.

[0066] With this design, the two installation areas of the handle structure 14 are not necessarily the two ends of the handle structure 14. The connection position between the handle structure 14 and the first fixing member 12, as well as the length of the handle structure 14, can be adjusted according to actual needs, which makes it more flexible.

[0067] In some embodiments, optionally, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, the portable energy storage device 1 also includes a wiring harness constraint 18. The wiring harness constraint 18 is provided on the handle structure 14. Branch wiring harnesses 162 pass through the wiring harness constraint 18, and the wiring harness constraint 18 is used to limit the two branch wiring harnesses 162.

[0068] By setting the wire harness constraint 18, the two branch wire harnesses 162 formed after the charging cable 16 is folded in half can be limited to avoid misalignment between the two branch wire harnesses 162, thereby affecting the installation of the handle structure 14. The wire harness constraint 18 can make the folded charging cable 16 more regular so that the folded charging cable 16 can be used as the handle structure 14.

[0069] Optionally, the harness constraint 18 has a constraint channel 182. Branch harnesses 162 pass through the constraint channel 182 of the harness constraint 18, and the harness constraint 18 is used to limit the two branch harnesses 162.

[0070] In one specific embodiment, there is one constraint channel 182, and two branch wire harnesses 162 pass through the same constraint channel 182.

[0071] In one specific embodiment, there are two constraint channels 182, with each branch wire harness 162 independently threaded through a corresponding constraint channel 182. This design allows the folded charging cable 16 to be more regular, so that the folded charging cable 16 can be used as a handle structure 14.

[0072] In some embodiments, the number of wire harness constraint members 18 may be at least one, that is, the wire harness constraint members 18 may be one, two or more, and the number, position and type of wire harness constraint members 18 may be flexibly set according to actual needs.

[0073] In one specific embodiment, the wire harness constraint 18 is disposed on the handle structure 14 and is located between the first mounting area 142 and the second mounting area 144. The function of the wire harness constraint 18 is to limit the movement of the two branch wire harnesses 162.

[0074] In one specific embodiment, the wire harness constraint member 18 is disposed in the first mounting area 142 of the handle structure 14. The wire harness constraint member 18 has two functions: first, to limit the two branch wire harnesses 162; second, to connect with the first fixing member 12 to realize the connection between the handle structure 14 and the host 10.

[0075] In one specific embodiment, the wire harness constraint 18 is disposed in the second mounting area 144 of the handle structure 14. The wire harness constraint 18 has two functions: first, to limit the two branch wire harnesses 162; second, to connect with the first fixing member 12 to realize the connection between the handle structure 14 and the host 10.

[0076] In some embodiments, optionally, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 and Figure 12 As shown, the wire harness constraint 18 is located in the first installation area 142, and the wire harness constraint 18 is detachably connected to the first fixing member 12.

[0077] Since the wiring harness constraint 18 and the first fixing member 12 are detachably connected, the connection between the handle structure 14 and the main unit 10 is also detachable. This design facilitates the assembly and disassembly of the handle structure 14. When the portable energy storage device 1 needs to be moved, the charging cable 16 can be folded in half to serve as the handle structure 14; when the portable energy storage device 1 needs to be used as an emergency power source, the handle structure 14 can be removed.

[0078] The wire harness constraint 18 has two functions. The first function is to limit the two branch wire harnesses 162. The second function is to detachably connect with the first fixing member 12 so as to realize the detachable connection between the handle structure 14 and the main unit 10.

[0079] In some embodiments, optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wire harness constraint 18 is a snap-on structure 181, which has two constraint channels 182. Each branch wire harness 162 is independently threaded through a corresponding constraint channel 182. This design allows the folded charging cable 16 to be more regular, so that the folded charging cable 16 can be used as a handle structure 14.

[0080] The buckle structure 181 also has a first limiting hole 183, and the first fastener 12 has a second limiting hole 122.

[0081] The portable energy storage device 1 also includes a first connector 191. The first connector 191 passes through the first limiting hole 183 and the second limiting hole 122 to realize the detachable connection between the wire harness constraint member 18 and the first fixing member 12.

[0082] The buckle structure 181 has two functions. The first function is to limit the two branch wire harnesses 162. The second function is to detachably connect with the first fixing member 12 so as to realize the detachable connection between the handle structure 14 and the main unit 10.

[0083] When the portable energy storage device 1 needs to be moved (e.g., carried or lifted), the first connector 191 is inserted through the first limiting hole 183 and the second limiting hole 122. At this time, the wire harness constraint member 18 and the first fixing member 12 are connected, so that the handle structure 14 and the main unit 10 are connected. The charging cable 16 is folded in half to serve as the handle structure 14. When the portable energy storage device 1 needs to be used as an emergency power source, the first connector 191 is removed so that the wire harness constraint member 18 and the first fixing member 12 are separated (disconnected). Then the handle structure 14 is separated from the main unit 10, and the user can remove the charging cable 16 for normal use.

[0084] In some embodiments, the first limiting member may optionally be a bolt, pin, screw, or limiting ring.

[0085] In one specific embodiment, the first limiting member is a bolt. The bolt passes through the first limiting hole 183 and the second limiting hole 122 to achieve a detachable connection between the wire harness constraint member 18 and the first fixing member 12.

[0086] In one specific embodiment, the first limiting member is a pin. The pin passes through the first limiting hole 183 and the second limiting hole 122 to achieve a detachable connection between the wire harness constraint member 18 and the first fixing member 12.

[0087] In one specific embodiment, the first limiting member is a screw. The screw passes through the first limiting hole 183 and the second limiting hole 122 to achieve a detachable connection between the wire harness constraint member 18 and the first fixing member 12.

[0088] In one specific embodiment, the first limiting member is a limiting ring. The limiting ring passes through the first limiting hole 183 and the second limiting hole 122 to achieve a detachable connection between the wire harness constraint member 18 and the first fixing member 12.

[0089] In one specific embodiment, the wire harness constraint 18 is a T-shaped fastener. The cross-sectional shape of the T-shaped fastener is approximately T-shaped. The T-shaped fastener is located in the first mounting area 142 and / or the second mounting area 144.

[0090] The T-shaped buckle has a constraint channel 182, through which the branch wire harness 162 passes. The T-shaped buckle is used to limit the two branch wire harnesses 162.

[0091] The T-shaped buckle also has a first limiting hole 183. The first fastener 12 includes a hook, and the hook has a second limiting hole 122.

[0092] The first connector 191 is an openable retaining ring. The retaining ring passes through the first limiting hole 183 and the second limiting hole 122 to achieve a T-shaped buckle and a detachable connection with the first retaining member 12.

[0093] In some embodiments, optionally, the main unit 10 is equipped with fasteners (first fasteners 12) with hooks on both sides. A T-shaped buckle is used to limit the two branch wire bundles 162 formed by folding the charging cable 16 in half. An openable ring (a specific form of the first connector 191) connects the T-shaped buckle and the hooks together, enabling the charging cable 16 to function as a handle. When the charging cable 16 needs to be used, it is removed, and one end is connected to the main unit 10, while the other end is connected to the device that needs charging.

[0094] In some embodiments, optionally, such as Figure 5 , Figure 6 and Figure 7 As shown, the wire harness constraint member 18 is a constraint band 184, which forms a ring structure 185, through which the branch wire harness 162 passes. The constraint band 184 is detachably connected to the first fixing member 12.

[0095] The constraint strap 184 has two functions. The first function is to limit the two branch wire harnesses 162. The second function is to detachably connect with the first fixing member 12 so as to realize the detachable connection between the handle structure 14 and the main unit 10.

[0096] Optionally, the restraint band 184 is made of a flexible material, such as chlorosulfonated polyethylene rubber (Hypalon). The restraint band 184 can be bent to form a ring structure 185 of suitable size. After the branch harness 162 is passed through the ring structure 185, the restraint band 184 can significantly limit the range of movement of the branch harness 162.

[0097] It should be noted that the number of constraint bands 184 is at least one, that is, there can be one, two or more constraint bands 184, and the constraint bands 184 can be flexibly set according to actual needs.

[0098] In one specific embodiment, the number of constraint bands 184 is one.

[0099] In one specific embodiment, there are two constraint bands 184. Each constraint band 184 forms a ring structure 185. Of the two ring structures 185, one ring structure 185 is fitted over the other ring structure 185. In other words, the two ring structures 185 are of different sizes, with the larger ring structure 185 (the outer ring structure 185) fitted over the smaller ring structure 185 (the inner ring structure 185).

[0100] The two constraint straps 184 are detachably connected via a second connector 192. Specifically, the second connector 192 is a snap-on structure.

[0101] Furthermore, the two constraint members are detachably connected to the first fixing member 12 via a first connector 191. Specifically, the first connector 191 is a bolt, screw, pin, or other type of connector.

[0102] Branch harnesses 162 are threaded through the inner ring structure 185, which limits the movement of the two branch harnesses 162. The outer ring structure 185 is used to connect the shoulder strap for easy movement of the portable energy storage device 1 by the user.

[0103] In some embodiments, optionally, the main unit 10 is equipped with fasteners (first fasteners 12) on both sides, and a double-layer Hypalon structural member (two restraint straps 184) is connected to the fasteners. The inner layer of the double-layer Hypalon structural member is used to limit the two branch wire harnesses 162, and the outer layer of the double-layer Hypalon structural member is used to connect the shoulder straps.

[0104] In some embodiments, optionally, such as Figure 11 and Figure 12 As shown, the wire harness constraint 18 includes a limiting groove 186, and the branch wire harness 162 is disposed in the limiting groove 186. A buckle 188 is provided at the opening 187 of the limiting groove 186, and the buckle 188 is used to open or close the opening 187 of the limiting groove 186.

[0105] The limiting groove 186 is used to limit the movement range of the two branch wire harnesses 162 to prevent the two branch wire harnesses 162 from being misaligned.

[0106] When the portable energy storage device 1 needs to be moved, the branch harness 162 is placed in the limiting groove 186, and the slot 187 of the limiting groove 186 is closed by the buckle 188. Then the harness constraint member 18 is connected to the first fixing member 12 so that the handle structure 14 is connected to the main unit 10. When the portable energy storage device 1 needs to be used as an emergency power source, it is not necessary to disconnect the harness constraint member 18 from the first fixing member 12. The buckle 188 can be opened directly and the branch harness 162 can be taken out.

[0107] When the handle structure 14 needs to be disassembled or assembled, the connection between the wire harness constraint 18 and the first fixing member 12 can be disassembled or assembled without considering the connection relationship between them. The slot 187 of the limiting groove 186 can be opened or closed directly to allow the branch wire harness 162 to be placed or removed. This design is simple in structure and more convenient to operate.

[0108] In one specific embodiment, the wire harness constraint 18 is an S-shaped double-opening metal part. The S-shaped double-opening metal part has two limiting grooves 186. Each limiting groove 186 has a buckle 188 at its opening 187.

[0109] Two branch wire harnesses 162 are inserted into the same limiting groove 186. The limiting groove 186 is used to limit the movement of the two branch wire harnesses 162.

[0110] Another limiting slot 186 is used to connect the shoulder strap to facilitate the user's movement of the portable energy storage device 1.

[0111] In some embodiments, optionally, the main unit 10 is equipped with fasteners (first fasteners 12) with hooks on both sides. An S-shaped double-opening metal piece is connected to the hooks, and the two branch wires 162 of the charging cable 16 pass through the limiting groove 186 at the lower end of the S-shaped double-opening metal piece to make the charging cable 16 serve as a handle structure 14. The limiting groove 186 at the upper end of the S-shaped double-opening metal piece is used to connect the shoulder strap.

[0112] At least a portion of the S-shaped double-opening metal piece (such as the hook-like structure at the bottom) is detachably connected to the lug to achieve a detachable connection between the handle structure 14 and the main unit 10.

[0113] In some embodiments, optionally, such as Figure 8 and Figure 9 As shown, the first fixing member 12 includes a first part 124 and a second part 126. The first part 124 is connected to the main unit 10 and has a mounting groove 128 for accommodating the branch wire harness 162 of the handle structure 14. The second part 126 is rotatably connected to the first part 124 to open or close the mounting groove 128.

[0114] Optionally, the first part 124 is a mounting base for connecting to the main unit 10. Optionally, the second part 126 is a flip-top structure.

[0115] When the portable energy storage device 1 needs to be moved, the branch harness 162 is placed in the mounting slot 128, and the mounting slot 128 is closed by rotating the second part 126. At this time, the handle structure 14 is connected to the main unit 10. When the portable energy storage device 1 needs to be used as an emergency power source, the mounting slot 128 can be opened directly by rotating the second part 126, and the branch harness 162 can be taken out. In this design, the branch harness 162 of the handle structure 14 is directly connected to the first fixing member 12, which is simple in structure and more convenient to operate.

[0116] In one specific embodiment, the first part 124 is detachably connected to the main unit 10, which facilitates the disassembly and assembly of the first part 124 by the staff and is beneficial for maintenance or replacement.

[0117] In one specific embodiment, the first part 124 is fixedly connected to the host 10 by welding, which is simple, convenient and quick to process.

[0118] In one specific embodiment, the first part 124 and the main unit 10 are integrated into one structure. Compared with the post-processing method, the mechanical properties are better, the connection strength is higher, and it is beneficial to reduce the number of parts and improve assembly efficiency.

[0119] In one specific embodiment, the wire harness constraint 18 is a "pig nose buckle" structure. The "pig nose buckle" structure is disposed on the handle structure 14 and is located between the first mounting area 142 and the second mounting area 144. The "pig nose buckle" structure has two constraint channels 182. Each branch wire harness 162 is independently threaded through a corresponding constraint channel 182.

[0120] The function of the "pig nose buckle" structure is to limit the movement of the two branch wire harnesses 162.

[0121] In some embodiments, optionally, the main unit 10 is equipped with flip-top metal fasteners (first fasteners 12) on both sides. By flipping open the flip-top metal fasteners (rotating the second part 126 to open the mounting slot 128), the charging cable 16 is inserted into the mounting slot 128, and the cover is fastened (rotating the second part 126 to close the mounting slot 128) to secure the charging cable 16, so that the charging cable 16 serves as a handle structure 14. The charging cable 16 is equipped with a "pig nose buckle" structure to prevent the charging cable 16 from falling off and to limit the branch wire harness 162.

[0122] In some embodiments, optionally, such as Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 11 As shown, the host 10 has a first side 102 and a second side 104 opposite each other.

[0123] At least one first fastener 12 is provided on the first side 102, and the first mounting area 142 is connected to the first side 102 through at least one first fastener 12.

[0124] At least one first fastener 12 is provided on the second side 104, and the second mounting area 144 is connected to the second side 104 through at least one first fastener 12.

[0125] The first fixing member 12 is symmetrically distributed on the two sides (first side 102 and second side 104) of the main unit 10. When the folded charging cable 16 is used as the handle structure 14, the pulling force is evenly transmitted to both sides of the main unit 10 through the first mounting area 142 and the second mounting area 144, so as to avoid deformation of the main unit 10 or detachment of the first fixing member 12 caused by unilateral force.

[0126] In one specific embodiment, the host 10 is a box structure, and the first side 102 and the second side 104 are two sides arranged opposite to each other.

[0127] In some embodiments, optionally, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the wire harness constraint 18 is also provided in the second installation area 144, and the wire harness constraint 18 is detachably connected to the first fixing member 12.

[0128] Since the wiring harness constraint 18 and the first fixing member 12 are detachably connected, the connection between the handle structure 14 and the main unit 10 is also detachable. This design facilitates the assembly and disassembly of the handle structure 14. When the portable energy storage device 1 needs to be moved, the charging cable 16 can be folded in half to serve as the handle structure 14; when the portable energy storage device 1 needs to be used as an emergency power source, the handle structure 14 can be removed.

[0129] The wire harness constraint 18 has two functions. The first function is to limit the two branch wire harnesses 162. The second function is to detachably connect with the first fixing member 12 so as to realize the detachable connection between the handle structure 14 and the main unit 10.

[0130] In some embodiments, the harness constraint 18 located in the second mounting area 144 is optionally a snap-fit ​​structure 181. The snap-fit ​​structure 181 is used to limit the movement of the two branch harnesses 162.

[0131] In some embodiments, optionally, the harness constraint 18 provided in the second mounting area 144 is a constraint band 184. The constraint band 184 is used to limit the two branch harnesses 162.

[0132] In some embodiments, the harness constraint 18 may optionally include a limiting groove 186, within which branch harnesses 162 are disposed. The limiting groove 186 is used to limit the movement of the two branch harnesses 162.

[0133] It should be noted that the wire harness constraint member 18 located in the first installation area 142 may be the same as or different from the wire harness constraint member 18 located in the second installation area 144. The number, position, and type of the wire harness constraint member 18 can be flexibly set according to actual needs.

[0134] In some embodiments, optionally, such as Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 11 As shown, the host 10 is provided with at least one charging interface 106 and at least one power supply interface 108.

[0139] It should be noted that the electrical equipment includes mobile phones, laptops, outdoor lights, small household appliances, and drones, among other devices.

[0140] By setting up a charging interface 106 and a power supply interface 108, when the power is insufficient, the user can replenish the battery pack of the host 10 through the charging interface 106; when there is a power demand, the user can supply power to the electrical equipment through the power supply interface 108 to meet the needs of temporary or emergency power use.

[0141] It should be noted that the number of charging ports 106 is at least one, that is, there can be one, two or more charging ports 106. The number, position and type of charging ports 106 can be flexibly set according to actual needs.

[0142] The number of power supply interfaces 108 is at least one, that is, there can be one, two or more power supply interfaces 108. The number, position and type of power supply interfaces 108 can be flexibly set according to actual needs.

[0143] It should be noted that the charging port 106 and the power supply port 108 can be located anywhere on the host 10, such as the top wall, bottom wall, or side wall. Furthermore, the cross-sectional shape of the charging port 106 and the power supply port 108 can be any shape, such as circular, square, or elliptical.

[0144] In one specific embodiment, the charging interface 106 is an AC input interface, which is used to connect to AC power.

[0145] In one specific embodiment, the charging interface 106 is a DC input interface, which is used to connect to a vehicle power supply or a solar power device.

[0146] In one specific embodiment, there are multiple power supply interfaces 108, including USB interfaces, AC output interfaces, and DC output interfaces. The USB interfaces include USB-A (one of the most common interface types under the USB standard) interfaces and USB-C (a next-generation universal interface under the USB standard).

[0147] It should be noted that USB-A ports are typically rectangular in shape, with a "foolproof" design on one side, such as a chamfer or label. USB-C ports are oval in shape and support reversible insertion.

[0148] In some embodiments, optionally, a marking is provided on the outer wall of the host 10 near the charging port 106 or the power supply port 108, such as "IN", "OUT", "15W MAX", "100W MAX", "140W MAX" and "IN / OUT".

[0149] In this designation, "IN" indicates that the interface here is a charging interface 106. "OUT" indicates that the interface here is a power supply interface 108. "IN / OUT" indicates that the interface here can function as both a charging interface 106 and a power supply interface 108. "15W MAX" indicates a maximum power of 15W, where "W" represents watts. "100W MAX" indicates a maximum power of 100W. "140W MAX" indicates a maximum power of 140W.
