The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] Please see Figure 1 and Figure 2 This application provides an energy storage power supply 100. The energy storage power supply 100 includes an energy storage body 10 and a charging cable 20. The energy storage body 10 is provided with a battery, a voltage conversion circuit and a transmission port 11. The voltage conversion circuit converts the battery power and outputs it to the outside through the transmission port 11. A first connector 12 and a second connector 13 are provided at intervals on the outside of the energy storage body 10.

[0031] The charging cable 20 includes a cable body 21 and a first connecting end 22 and a second connecting end 23 disposed at both ends of the cable body 21. The first connecting end 22 is detachably connected to the first connecting member 12, and the second connecting end 22 is detachably connected to the second connecting member 13. The charging cable 20 has a first operating state and a second operating state. In the first operating state, the first connecting end 22 is connected to the first connecting member 12, and the second connecting end 23 is connected to the second connecting member 13, with the charging cable 20 serving as a handle for the energy storage body 10. In the second operating state, the first connecting end 22 is detached from the first connecting member 12, and the second connecting end 23 is detached from the second connecting member 13. The first connecting end 22 or the second connecting end 23 can be electrically connected to the transmission port 11 to transmit electrical energy through the charging cable 20.

[0032] Specifically, the energy storage power supply 100 of this application can be an outdoor power supply or other types of power supply, and there is no limitation here. The number of transmission ports 11 can be one or more, and the number of transmission ports 11 can be set according to the requirements, and there is no limitation here.

[0033] The energy storage body 10 is externally provided with a first connector 12 and a second connector 13 at intervals. The first connecting end 22 is detachably connected to the first connector 12, and the second connecting end 22 is detachably connected to the second connector 13. This means that the energy storage body 10 of the energy storage power supply 100 of this application has two connectors, allowing the two connecting ends of the charging cable 20 to be detachably connected to the two connectors respectively. This eliminates the need for users to carry the charging cable 20 separately when using the energy storage power supply 100, avoiding the embarrassment of forgetting or not being able to find the charging cable 20. The detachable connection method can be a snap-fit ​​connection or a magnetic connection, which is not limited here.

[0034] In the first working state, since the two connecting ends of the charging cable 20 can be connected to the two connecting parts respectively, the energy storage power supply 100 can be carried by using the portable charging cable 20. That is, the charging cable 20 can be used as a handle for the energy storage body 10, so that there is no need to set a separate handle on the energy storage power supply 100, reducing manufacturing costs and making it easy to carry the energy storage body 10 and the charging cable 20 together.

[0035] In the second operating state, after the first connecting end 22 is connected to the first connecting member 12 and the second connecting end 22 is connected to the second connecting member 13, both ends of the charging cable 20 can be firmly connected to the energy storage body 10 and are not easily detached. When it is necessary to remove the charging cable 20 from the energy storage body 10 for use, the first connecting end 22 can be detached from the first connecting member 12 and the second connecting end 22 can be detached from the second connecting member 13, so that the charging cable 20 can be used normally.

[0036] The first connection terminal 22 or the second connection terminal 23 can be electrically connected to the transmission port 11 to transmit electrical energy through the charging cable 20. This means that when the energy storage body 10 needs to be charged, electrical energy can be input to the energy storage body 10 using the charging cable 20, and the transmission port 11 is used as an electrical energy input port at this time; when the energy storage body 10 discharges to an external electronic device, electrical energy can also be output to the external electronic device using the charging cable 20, and the transmission port 11 is used as an electrical energy transmission port at this time.

[0037] Thus, the energy storage power supply 100 of this application can detachably connect the charging cable 20 to the energy storage body 10, allowing the charging cable 20 to be connected together with the energy storage body 10, preventing the loss of the charging cable 20 and improving the user experience of the energy storage power supply 100. In addition, the charging cable 20 of this application can also serve as a handle, eliminating the need for a separate handle on the energy storage power supply 100, reducing manufacturing costs and making it easier to carry the energy storage body 10 and the charging cable 20 together.

[0038] In some embodiments, the energy storage body 10 is columnar, and a first connector 12 and a second connector 13 are disposed opposite each other on the outer side wall of the energy storage body 10.

[0039] Specifically, for example, when the energy storage body 10 is cylindrical, the first connector 12 and the second connector 13 can be symmetrically arranged on the outer side wall of the energy storage body 10, or the first connector 12 and the second connector 13 can be asymmetrically arranged on the outer side wall of the energy storage body 10; this is not limited. When the energy storage body 10 is rectangular, the first connector 12 and the second connector 13 can be symmetrically arranged on the two opposite outer side walls of the energy storage body 10, or the first connector 12 and the second connector 13 can be asymmetrically arranged on the two opposite outer side walls of the energy storage body 10; this is not limited.

[0040] That is, the first connector 12 and the second connector 13 of this application can be set on the outer side wall of the energy storage body 10, so that the charging cable 20 can be connected to the first connector 12 and the second connector 13 respectively, and the energy storage power supply 100 of this application can be formed into a handbag shape, which is convenient for users to lift the energy storage power supply 100 by hand or carry it on their shoulder with the charging cable 20. It is convenient to carry and will not lose the charging cable 20. It is beautiful and convenient.

[0041] In some embodiments, the first connecting end 22 is snapped into the first connecting member 12, and / or the second connecting end 23 is snapped into the second connecting member 13.

[0042] Specifically, the first connecting end 22 is snapped to the first connecting member 12, and / or the second connecting end 23 is snapped to the second connecting member 13, including the following situations: (1) the first connecting end 22 is snapped to the first connecting member 12, and the second connecting end 23 is not snapped to the second connecting member 13, but can be connected in other ways, such as the second connecting end 23 is connected to the second connecting member 13 by bolts, magnetic attraction or other detachable methods; (2) the second connecting end 23 is snapped to the second connecting member 13, and the first connecting end 22 is not snapped to the first connecting member 12, but can be connected in other ways, such as the first connecting end 22 is connected to the first connecting member 12 by bolts, magnetic attraction or other detachable methods; (3) the first connecting end 22 is snapped to the first connecting member 12, and the second connecting end 23 is snapped to the second connecting member 13.

[0043] In one example, such as Figure 1 and Figure 2 As shown, the first connecting end 22 is snapped into the first connecting member 12, and the second connecting end 23 is snapped into the second connecting member 13. Specifically, the first connecting end 22 can be one charging port of the charging cable 20, and the second connecting end 23 can be the other charging port of the charging cable 20. The first connecting member 12 and the second connecting member 13 can have slots inside that are adapted to the shape and width of the charging ports, so that the two charging ports at both ends of the charging cable 20 can be snapped into the two slots of the first connecting member 12 and the second connecting member 13 respectively, thereby realizing the detachable connection of the charging cable 20 to the energy storage body 10.

[0044] In another example, the first connection end 22 and the second connection end 23 may also be provided with an assembly component with a slot adapted to the charging port. Correspondingly, the first connector 12 and the second connector 13 are buckles fixedly connected to the energy storage body 10, so that the buckles on both sides of the energy storage body 10 can be respectively engaged in the two slots at both ends of the charging cable 20, and the charging cable 20 can be detachably connected to the energy storage body 10.

[0045] Thus, the energy storage power supply 100 of this application can detachably connect the charging cable 20 to the energy storage body 10 by means of a snap-fit ​​connection.

[0046] In some embodiments, the first connection end 22 and the second connection end 23 include a plug 221, and the first connector 12 or the second connector 13 includes a slot 131. The plug 221 is inserted into the slot 131, and the plug 221 and the slot 131 are detachably connected.

[0047] That is, the charging cable 20 of this application can be detachably connected to the slot 131 on the energy storage body 10 via the plug 221, which is convenient to carry the charging cable 20 without losing it, and is both beautiful and convenient.

[0048] Please see Figure 3 and Figure 4 In some embodiments, a limiting protrusion 2212 is provided on the first sidewall 2211 of the plug 221. The slot 131 includes a bottom surface 1311 and a second sidewall 1312 surrounding the bottom surface 1311. An elastic member 1313 facing the slot opening is connected to the bottom surface 1311. A limiting groove 1314 is provided on the second sidewall 1312. The limiting groove 1314 includes a bent and connected first groove 13141 and a second groove 13142. The first groove 13141 is arranged along the insertion direction. The closed end of the second groove 13142 is close to the slot opening. The limiting protrusion 2212 enters through the first groove 13141. After the plug 221 contacts the elastic member 1313 and causes the elastic member 1313 to contract by a preset distance, the limiting protrusion 2212 is engaged in the second groove 13142.

[0049] Specifically, the elastic element 1313 can be a spring or rubber, etc., without limitation. After the plug 221 contacts the elastic element 1313 and the elastic element 1313 contracts to a preset distance, when the limiting protrusion 2212 is engaged in the second groove 13142, the elastic element 1313 can protect the plug 221 from being damaged by impact with the hard bottom wall of the slot 131. The preset distance can be 0.1cm, 0.2cm, 0.3cm, 0.4cm, 0.45cm, 0.46cm, 0.47cm, 0.48cm, 0.49cm or 0.5cm, without limitation.

[0050] The shape of the limiting protrusion 2212 can be adapted to the shape of the limiting groove 1314. For example, if the limiting protrusion 2212 is cylindrical, the limiting groove 1314 can also be cylindrical; if the limiting protrusion 2212 is round-square prism, the limiting groove 1314 can also be square prism.

[0051] The limiting groove 1314 includes a first groove 13141 and a second groove 13142 that are bent and connected. This means that the limiting groove 1314 needs to function as a limiting groove. The first groove 13141 and the second groove 13142 can be bent at a certain angle to form the limiting groove 1314, allowing the limiting protrusion 2212 to be held in place by the second groove 13142. The total bending angle between the first groove 13141 and the second groove 13142 can be, for example, 120°, 125°, 128°, 130°, 140°, 150°, 160°, 170°, 180°, or 185°. In other words, the total bending angle between the second groove 13142 and the first groove 13141 only needs to ensure that the end of the second groove 13142 faces the opening of the slot 131, and that the second groove 13142 achieves its limiting and holding function. Figure 3 and Figure 4 As shown, the total bending angle between the first groove 13141 and the second groove 13142 is 180°.

[0052] The first slot 13141 is arranged along the insertion direction, and the closed end of the second slot 13142 is close to the slot opening. This means that the second slot 13142 can be bent in the opposite direction of the insertion direction towards the slot opening to form a hook shape. Figure 3 and Figure 4 As shown, when the charging cable 20 needs to be lifted, the limiting protrusion 2212 can be stably held by the second groove 13142, making it less likely for the plug to slip out of the first groove 13141.

[0053] In detail, the limiting point of the limiting protrusion 2212 in the second groove 13142 is provided at a predetermined distance from the starting point of the bend. The predetermined distance can be, for example, 0.4 cm or other distances, so that when the charging cable 20 needs to be lifted, the limiting protrusion 2212 can be stably held by the second groove 13142, making it less likely for the plug to slip out of the first groove 13141. It can also make it easier for the charging cable 20 to slide out of the second groove 13142 and finally slide out of the first groove 13141 when it needs to be removed from the energy storage body 10.

[0054] In some embodiments, the plug 221 is provided with a resilient buckle 2212, and the slot 131 is provided with a slot, wherein the resilient buckle 2212 can be engaged in the slot.

[0055] Specifically, the elastic buckle 2212 can be a buckle made of elastic material, such as spring steel, thermoplastic polyurethane, etc., without limitation.

[0056] That is, the plug 221 of the charging cable 20 can be provided with one or more elastic clips 2212, and correspondingly, the slot 131 can be provided with one or more slots, so that one or more elastic clips 2212 can be locked in one or more slots. Understandably, the more elastic clips 2212 and slots are provided, the more stable the connection between the charging cable 20 and the energy storage body 10 will be.

[0057] In some embodiments, the first connecting end 22 is threaded to the first connecting member 12, and / or the second connecting end 23 is threaded to the second connecting member 13.

[0058] Specifically, the first connecting end 22 is threaded to the first connecting member 12, and / or the second connecting end 23 is threaded to the second connecting member 13, including the following situations: (1) the first connecting end 22 is threaded to the first connecting member 12, and the second connecting end 23 is not threaded to the second connecting member 13, but can be connected in other ways, such as by snap-fit ​​connection, bolt connection, magnetic connection or other detachable method; (2) the second connecting end 23 is threaded to the second connecting member 13, and the first connecting end 22 is not threaded to the first connecting member 12, but can be connected in other ways, such as by snap-fit ​​connection, bolt connection, magnetic connection or other detachable method; (3) the first connecting end 22 is threaded to the first connecting member 12, and the second connecting end 23 is threaded to the second connecting member 13.

[0059] In detail, when the first connecting end 22 is threadedly connected to the first connecting member 12, the outer peripheral wall of the plug 221 of the first connecting end 22 may be provided with an external thread, and the inner wall of the slot 131 of the first connecting member 12 may be provided with an internal thread. The external thread and the internal thread match, so that the first connecting end 22 can rotate several times before being threadedly connected to the first connecting member 12. Similarly, when the second connecting end 23 is threadedly connected to the second connecting member 13, the outer peripheral wall of the plug 221 of the second connecting end 23 may be provided with an external thread, and the inner wall of the slot 131 of the second connecting member 13 may be provided with an internal thread. The external thread and the internal thread match, so that the second connecting end 23 can rotate several times before being threadedly connected to the second connecting member 13.

[0060] Thus, the two connecting ends of the charging cable 20 of this application can also be detachably connected to the two connecting parts 13 of the energy storage body 10 by means of threaded connection.

[0061] In some embodiments, the first connecting end 22 is magnetically connected to the first connecting member 12, and / or the second connecting end 23 is magnetically connected to the second connecting member 13.

[0062] Specifically, the first connecting end 22 is magnetically connected to the first connecting member 12, and / or the second connecting end 23 is magnetically connected to the second connecting member 13, including the following situations: (1) the first connecting end 22 is magnetically connected to the first connecting member 12, but the second connecting end 23 is not connected to the second connecting member 13 by magnetic attraction, but can be connected by other means, such as the second connecting end 23 and the second connecting member 13 by snap-fit ​​connection, bolt connection or other detachable means; (2) the second connecting end 23 is magnetically connected to the second connecting member 13, but the first connecting end 22 is not connected to the first connecting member 12 by magnetic attraction, but can be connected by other means, such as the first connecting end 22 and the first connecting member 12 by snap-fit ​​connection, bolt connection or other detachable means; (3) the first connecting end 22 is magnetically connected to the first connecting member 12, and the second connecting end 23 is magnetically connected to the second connecting member 13.

[0063] That is, the first connector 12 and the second connector 13 of this application may be provided with magnetic blocks. Since the first connector 22 and the second connector 23 of the charging cable 20 can both be made of metal, the two ends of the charging cable 20 can be magnetically connected to the first connector 12 and the second connector 13, so as to conveniently and quickly detachably connect the charging cable 20 to the energy storage body 10, avoid losing the charging cable 20, and improve the user experience of the energy storage power supply 100.

[0064] Please see Figure 3 and Figure 5 In some embodiments, the first connector 12 or the second connector 13 includes a first sub-connector 121 and a second sub-connector 122 with a slot. The first sub-connector 121 is fixedly connected to the energy storage body 10, the second sub-connector 122 is movably connected to the first sub-connector 121, and the second sub-connector 13 is detachably connected to the first connecting end 22 or the second connecting end 23.

[0065] Specifically, the first sub-connector 121 being fixedly connected to the energy storage body 10 means that the first sub-connector 121 and the energy storage body 10 can be connected by threaded connection, snap-fit ​​connection or other means.

[0066] The second sub-connector 122 is movably connected to the first sub-connector 121, meaning that the first sub-connector 121 and the second sub-connector 122 can be inseparable from each other and have a certain degree of mobility, so that when the charging cable 20 acts as a handle, it can rotate according to the degree of mobility between the first sub-connector 121 and the second sub-connector 122.

[0067] In other words, the first connector 12 or the second connector 13 provided on the energy storage body 10 in this application can not only be a single structure with a slot or buckle that is fixedly connected to the energy storage body 10, but the first connector 12 or the second connector 13 can also be composed of two parts, the first sub-connector 121 and the second sub-connector 122, which are detachably connected together, making the manufacturing flexible.

[0068] The first sub-connector 121 and the second sub-connector 122 can both be made of metal, such as iron, steel or aluminum, without limitation.

[0069] Thus, when the second sub-connector 122 is not connected to the charging cable 20, the second sub-connector 122 can be used as a handle; when the second sub-connector 122 is connected to the charging cable 20, the charging cable 20 is used as a handle, making the handle design of the energy storage power supply 100 of this application more flexible.

[0070] Please see Figure 3 and Figure 5 In some embodiments, the first connector 12 or the second connector 13 further includes a third sub-connector 123. The third sub-connector 123 connects the first sub-connector 121 and the second sub-connector 122, and both the first sub-connector 121 and the second sub-connector 122 are rotatably connected to the third sub-connector 123.

[0071] In other words, the first connector 12 or the second connector 13 provided on the energy storage body 10 in this application can not only be a single structure with a slot or buckle that is fixedly connected to the energy storage body 10, but the first connector 12 or the second connector 13 can also be composed of two parts, the first sub-connector 121 and the second sub-connector 122, which are detachably connected together, making manufacturing flexible. In addition, the first connector 12 or the second connector 13 can also be composed of three parts, the first sub-connector 121, the second sub-connector 122 and the third sub-connector 123, which are detachably connected together, making manufacturing flexible.

[0072] The first sub-connector 121, the second sub-connector 122, and the third sub-connector 123 can all be made of metal, such as iron, steel, or aluminum, without limitation. When the first sub-connector 121, the second sub-connector 122, and the third sub-connector 123 are all metal parts, they are not easily damaged, making the first connector 121 and the second connector 123 more durable.

[0073] In other embodiments of this application, the first sub-connector 121 and the second sub-connector 122 are made of metal, such as iron, steel or aluminum, and are not limited thereto. The third sub-connector 123 is made of soft fabric, such as imitation nylon fabric or other types of fabric, so that the first sub-connector 121 and the second sub-connector 122 can be rotatably connected through the third sub-connector 123, so that the charging cable 20 has a rotating function when used as a handle, and the design is more flexible.

[0074] Thus, when the second sub-connector 122 is not connected to the charging cable 20, the second sub-connector 122 and the third sub-connector 123 can be used as handles; when the second sub-connector 122 is connected to the charging cable 20, the charging cable 20 is used as a handle, making the handle design of the energy storage power supply 100 of this application more flexible.

[0075] In some embodiments, the first sub-connector 121 and the second sub-connector 122 are metal parts, and the third sub-connector 123 is a kit made of a soft material.

[0076] Specifically, the first sub-connector 121 can be as follows: Figure 3 The metal round nail shown, the second sub-connector 122 may include, for example, Figure 3 The metal clip 1221 shown has a slot 131 on one side and an openable metal buckle 1222 that is sleeved with the metal clip 1221.

[0077] The term "soft material" refers to a material that can be adjusted at any angle, such as imitation nylon fabric. Therefore, the third sub-connector 123 can be a collar made of imitation nylon fabric.

[0078] In other words, in order to enable the charging cable 20 to be used as a handle and to have a rotatable function, a combination structure can be adopted. The metal round nail can be fixedly connected to the energy storage body 10 by inserting it through one end of the imitation nylon fabric. The metal buckle 1222 is fitted onto the other end of the imitation nylon fabric in a sleeve manner. The metal snap fastener 1221 can be fitted onto the metal buckle 1222 in a sleeve manner, so as to realize the rotatable function of the charging cable 20 when it is used as a handle.

[0079] The openable metal buckle 1222 of this application is similar to the metal ring of a keychain, allowing items fitted inside the metal buckle 1222 to be removed from the ring in one direction and separated from the metal buckle 1222. In other words, because the metal buckle 1222 of this application has an opening that allows it to be removed from its own ring, the metal buckle 1222 can be removed from the imitation nylon fabric, making the replacement of the second sub-connector 122 formed by the metal clip 1221 and the metal buckle 1222 more flexible. The metal buckle 1222 can also be used to fix shoulder straps and other accessories, realizing a multi-functional design and improving the user experience of the energy storage power supply 100.

[0080] In some embodiments, the first sub-connector 121, the second sub-connector 122, and the third sub-connector 123 are metal parts.

[0081] That is to say, the first sub-connector 121, the second sub-connector 122 and the third sub-connector 123 of this application can all be made of metal, such as iron, steel or aluminum, etc., without limitation.

[0082] Thus, the first sub-connector 121, the second sub-connector 122 and the third sub-connector 123 of this application are all metal parts, which are strong and not easily damaged, making the first connector 121 and the second connector 13 more durable.

[0083] Please see Figure 2 In some embodiments, the first connection end 22 or the second connection end 23 further includes an electrical connection terminal 222. The electrical connection terminal 222 is disposed at the end of the plug 221 and is received in the slot 131. The electrical connection terminal 222 is used to electrically connect to the transmission port 11 to transmit electrical energy through the charging cable 20.

[0084] Specifically, the length, width, and thickness of the electrical connection terminal 222 are all smaller than those of the plug 221, so that the position of the plug 221 and the position of the electrical connection terminal 222 in the charging cable 20 can be clearly seen, which facilitates the connection and disconnection between the charging cable 20 and the energy storage body 10.

[0085] Electrical connection terminal 222 is disposed at the end of plug 221, that is, electrical connection terminal 222 is disposed protruding from one end of plug 221.

[0086] Electrical connection terminal 222 can be connected to the transmission port 11 of the energy storage body 10 and the electrical connection port of external electronic devices to realize the charging or discharging process between the energy storage power supply 100 and external electronic devices.

[0087] Please see Figure 3 and Figure 4In some embodiments, a limiting protrusion 2212 is provided on the first sidewall 2211 of the plug 221. The slot 131 includes a bottom surface 1311 and a second sidewall 1312 surrounding the bottom surface 1311. An elastic member 1313 facing the slot opening is connected to the bottom surface 1311. A limiting groove 1314 is provided on the second sidewall 1312. The limiting groove 1314 includes a bent and connected first groove 13141 and a second groove 13142. The first groove 13141 is arranged along the insertion direction. The closed end of the second groove 13142 is close to the slot opening. The limiting protrusion 2212 enters through the first groove 13141. After the plug 221 contacts the elastic member 1313 and causes the elastic member 1313 to contract by a preset distance, the limiting protrusion 2212 is engaged in the second groove 13142. The electrical connection terminal 222 is accommodated in the hollow area inside the elastic member 1313.

[0088] In other words, when the upper limit protrusion 2212 of the plug 221 is engaged with the second groove 13142 and the plug 221 is in contact with the elastic member 1313, the electrical connection terminal 222 can be accommodated within the elastic member 1313, and the electrical connection terminal 222 does not contact the elastic member 1313, thus protecting the electrical connection terminal 222 from damage due to impact. The structure of the limit protrusion 2212 and the elastic member 1313 is as described above and will not be repeated here.

[0089] In some embodiments, the first connector 12 and / or the second connector 13 are provided with anti-slip stripes.

[0090] That is, the energy storage power supply 100 of this application can have anti-slip stripes on the first connector 12, or only on the second connector 13, or both on the first connector 12 and the second connector 13.

[0091] The anti-slip stripes can be horizontal stripes, vertical stripes, cross stripes, or spiral stripes, etc. There are no restrictions, as long as they can play an anti-slip role.

[0092] Thus, this application can achieve a better anti-slip effect by setting anti-slip stripes on the first connector 12 or the second connector 13.

[0093] In some implementations, the voltage conversion circuit is an inverter or a DC-DC converter.

[0094] That is, the energy storage power supply 100 of this application can convert the DC power input from the solar panel connected to the energy storage power supply 100 into AC power through an inverter, thereby providing AC power to external electronic devices connected to the transmission port 11.

[0095] In addition, the energy storage power supply 100 of this application can also convert the DC power output from the internal battery of the energy storage power supply 100 into DC power suitable for external electronic devices through a DC conversion circuit, thereby providing DC power to external electronic devices connected to the transmission port 11.

[0096] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
