Description

Technical Field

[0001] The present application relates to the field of shared charging technology, and in particular to a power bank with interchangeable cables and a shared charging device. Background Art

[0002] At present, with the rapid development of mobile electronic products, outdoor battery life faces great challenges. Shared charging devices distributed on the streets, shopping malls and other places have solved this problem well.

[0003] Shared charging systems contain multiple power banks. Users scan a QR code to pay a deposit and fee to borrow a power bank, and then return it after use. Shared charging systems are purchased from manufacturers by the vendors and deployed in various areas. As the number of rentals and returns increases, the power bank's power cords inevitably become damaged and loose. Therefore, the vendors must promptly return damaged power banks to the manufacturer for repair, a time-consuming process.

[0004] Furthermore, shared charging devices are experiencing new growth overseas. An increasing number of businesses are promoting this sharing model abroad. However, this also presents challenges with power bank damage and repairs. Currently, due to the high transportation costs and repair cycles between domestic and international locations, damaged power banks are often scrapped. This increases business operating costs and wastes resources. Utility Model Content

[0042] In order to illustrate the technical solution described in this application, the following is a detailed description with reference to specific drawings and embodiments.

[0043] See also Figure 1 、 Figure 3 and Figure 4As shown, the embodiment of the present application first provides a replaceable power bank 100, which includes a housing 2, a battery cell assembly 3, a circuit board 4 and at least one power cord 5. Specifically, the housing 2 includes a shell body 22 and a cover 21. The housing 2 is a semi-enclosed structure with a window 220 formed thereon. The cover 21 has at least two positions relative to the housing 2. In the first position, the cover 21 is installed at the window 220 and closes the window 220. Please refer to the following. Figure 1 As shown, at this time, the cover 21 and the shell body 22 define an inner cavity. In the second position, the cover 21 allows the window 220 to be opened to allow the corresponding structure at the window 220 to be exposed. Please refer to Figure 3 As shown; the battery cell assembly 3 is arranged in the inner cavity for storing electrical energy; the circuit board 4 is arranged in the inner cavity and is electrically connected to the battery cell assembly 3; the first end 51 of the power cord 5 is electrically connected to the surface of the circuit board 4 on the side facing the cover body 21, and the multiple connection areas formed between the first end 51 and the circuit board 4 correspond to the above-mentioned window 220 and the cover body 21, and the second end 52 of the power cord 5 is located outside the shell 2.

[0044] The second end 52 of the power cord 5 is used to connect to an electrical device (such as a mobile phone, tablet computer, or other mobile electronic device) to provide power to the electrical device.

[0045] The interchangeable power bank 100 provided in the embodiment of the present application has a window 220 provided on its housing 2, and a cover 21 capable of closing and opening the window 220. By shifting the cover 21 between different positions, multiple connection areas provided at the window 220 can be exposed. At this point, the connection areas can be manipulated to disconnect the physical connection between the first end 51 and the circuit board 4, thereby allowing operations such as repairing the power cord 5, re-establishing the connection area, or replacing the power cord 5.

[0046] In this way, when a fault occurs in the power cord 5 itself or in the connection area between the power cord 5 and the circuit board 4, the connection area can be repaired or the power cord 5 can be replaced by opening the cover 21. There is no need to return the entire power bank to the manufacturer for repair, nor is there any need to scrap the entire power bank, thus saving users material costs, repair time, repair costs, etc.

[0047] The power cord 5 includes multiple conductors. In one embodiment, the first ends 51 of the conductors (i.e., corresponding to the first end 51 of the power cord 5) are connected to pads on the circuit board 4 by soldering, for example, by forming solder joints. When the window 220 is opened and the solder joints are exposed, the conductors can be removed from the pads by melting the solder. After replacing or repairing the power cord 5, the first ends 51 of the conductors can then be soldered to the pads.

[0048] In another embodiment, the first end 51 of the wire is physically connected to the pad (or other terminal capable of achieving electrical connection) on the circuit board 4 via a clamping member (not shown). Specifically, the first end 51 of the wire is pressed against the pad with a certain pressure. When the window 220 is opened and the clamping members are exposed, the clamping members can be loosened to release the wire from the pad or terminal. After replacing or repairing the power cord 5, the first end 51 of the wire can be re-clamped to the pad or terminal on the circuit board 4.

[0049] Without limitation thereto, in more embodiments, the first end 51 of the wire can be electrically connected to the circuit board 4 in a repeatable manner through other means.

[0050] The embodiment of the present application provides a removable power bank 100, wherein the battery cell assembly 3 is a secondary battery cell, that is, after the battery cell assembly 3 is discharged, the active material can be activated by charging and continued to be used. Figure 2 、 Figure 4 and Figure 5 As shown, in one embodiment, the interchangeable power bank 100 further includes a charging interface 7 provided on the shell body 22. The charging interface 7 is electrically connected to the circuit board 4 and is used to connect to an external power source (not shown) to charge the battery cell assembly 3 via the circuit board 4 through the external power source.

[0051] In one embodiment, please refer to Figure 1 、 Figure 2 、 Figure 3 As shown, the charging interface 7 includes a first charging interface 71 and a second charging interface 72 . The first charging interface 71 and the second charging interface 72 are of different types. This is to facilitate users to use different methods to charge the battery cell assembly 3 .

[0052] For example, Figure 1 、 Figure 3 and Figure 5 As shown in , in one embodiment, the first charging interface 71 is configured to allow the user to charge the battery cell assembly 3 by means of an external data cable. At this time, the first charging interface 71 can be a USB-A port, a USB-C port, a Micro USB port, a Lightning port, etc.; Figure 2 、 Figure 4 and Figure 5 As shown, the second charging interface 72 is configured to allow the user to charge the interchangeable power bank 100 by placing it in a charging base-style structure. For example, the interchangeable power bank 100 is a rentable power bank in a shared charging device. When the interchangeable power bank 100 is returned to the device body, its second charging interface 72 can abut and electrically connect with the electrical connection terminal in the device body. In this way, the battery cell assembly 3 can be charged through the device body.

[0053] In other optional embodiments, depending on the different application forms of the interchangeable power bank 100, the type and quantity of the charging interface 7 can have other settings, which will not be repeated here.

[0054] In one embodiment, the interchangeable power bank 100 has multiple power cords 5, and the second sections of the multiple power cords 5 have different interface types to adapt to different interface types of different electronic devices. Figure 2 、 Figure 3 and Figure 5 shown.

[0055] For example, Figure 4 and Figure 5 As shown in , in this embodiment, the number of power cords 5 can be three, and the interfaces of their second ends 52 are respectively a USB-C port, a Micro USB port, and a Lightning interface. Not limited to this, in other optional embodiments, there can be other numbers of power cords 5, and the interface of the second end 52 of each power cord 5 can be configured as needed. It should be understood that with technological developments, for the power cord 5 and charging interface 7, more universal interfaces that may appear in the future can also be used in the interchangeable power bank 100 of the embodiment of the present application without departing from the scope of the embodiment of the present application.

[0056] like Figure 3 、 Figure 4 and Figure 5 As shown, in one embodiment, when the cover 21 is in the second position, it is completely separated from the shell body 22. In one embodiment, the interchangeable power bank 100 includes one or more locking members (not shown). The cover 21 is provided with a corresponding number of mounting holes 210, and the shell body 22 is provided with corresponding matching holes 2210. The locking members pass through the mounting holes 210 and the matching holes 2210 to detachably fix the cover 21 to the shell body 22.

[0057] Optionally, there are multiple locking members to enable multiple-point fixed connection between the cover 21 and the shell body 22, thereby ensuring the installation stability of the cover 21 on the shell 2. According to the size of the cover 21, the number of mounting holes 210 is designed to take into account the connection stability and not affect the internal structure.

[0058] In other optional embodiments, when the cover 21 is in the second position, one end may be connected to the housing body 22. For example, the cover 21 and the housing body 22 may be hingedly connected, and the window 220 may be opened by flipping the cover 21. In this case, the arrangement of the locking member, mounting hole 210, and mating hole 2210 may refer to the previous embodiment and will not be repeated here.

[0059] Please refer to Figure 4 and Figure 5As shown, in one embodiment, the housing body 22 includes an upper housing 221 and a lower housing 222. The upper housing 221 and the lower housing 222 are two relatively concave flat structures. When the upper housing 221 and the lower housing 222 are connected relative to each other, the aforementioned inner cavity is formed therebetween. In other optional embodiments, at least one of the upper housing 221 and the lower housing 222 can be further formed as separate parts and then connected. This facilitates the processing and manufacturing of the housing body 22, as well as the assembly of components such as the battery cell assembly 3 and the circuit board 4 therein.

[0060] The definition of the upper shell 221 and the lower shell 222 is only used for distinction, and the housing 2 may not have a clear upper and lower direction when in use.

[0061] In practical applications, such as Figure 4 and Figure 5 As shown, the power cord 5 is a flexible structure, and its part outside the shell 2 can be fixed on the side surface of the upper shell 221 away from the lower shell 222 by bending to fit the outer surface of the shell 2, and can also be roughly straightened for user use.

[0062] In one embodiment, if Figure 4 and Figure 5 As shown, the window 220 is provided in the lower shell 222, and the mating hole 2210 is provided on the inner side of the upper shell 221 facing the lower shell 222. The locking member includes a bolt, and the mating hole 2210 is a threaded hole. The head of the bolt is restrained on the side surface of the cover 21 facing away from the upper shell 221, and the threaded portion of the bolt enters the mating hole 2210. In this case, the mounting hole 210 can be a threaded hole or a non-threaded hole.

[0063] In an alternative embodiment, see Figure 4 and Figure 5 As shown, the window 220 is a notch provided in the lower shell 222 and communicating with the periphery of the lower shell 222. In other words, the window 220 on the lower shell 222 is not a closed annular opening. This facilitates the processing and manufacturing of the window 220 on the lower shell 222. Furthermore, the location of the window 220 at one end of the lower shell 222 (e.g., one end in the longitudinal direction) makes it easier to align with the position of the circuit board 4, as the other end of the lower shell 222 can be positioned corresponding to the battery cell assembly 3.

[0064] In order to facilitate the extension of the power line 5 from the circuit board 4 to the outside of the housing 2, in one embodiment, the housing 2 is provided with a wire outlet hole 225 corresponding to each power line 5, see Figure 4 shown.

[0065] Alternatively, see Figure 4 and Figure 5As shown, the wire outlet hole 225 includes a recessed portion 2251 provided at the edge of the upper shell 221 and a recessed portion 2251 provided at the edge of the cover 21. After the upper shell 221 and the cover 21 are docked, the two recessed portions 2251 are relatively connected to form a wire outlet hole 225. The formation of the wire outlet hole 225 at the edge of the upper shell 221 and the edge of the cover 21 also facilitates its processing and manufacturing in a simpler manner.

[0066] In other optional embodiments, the wire outlet hole 225 can also be formed between the edges of the upper shell 221 and the lower shell 222, or between the edges of the cover body 21 and the lower shell 222.

[0067] Next, see Figure 4 and Figure 5 As shown, and in conjunction with Figures 6 to 8 As shown, in one embodiment, the lower shell 222 is provided with at least one first positioning protrusion 2221 protruding into the window 220. The first positioning protrusion 2221 is configured to abut against the inner side surface (the surface facing the circuit board 4) of the cover 21. During assembly of the cover 21, the abutment of the first positioning protrusion 2221 against the inner side surface of the cover 21 ensures that the cover 21 and the lower shell 222 are aligned in the thickness direction. For example, by setting the depth of the window 220 to be the same as the thickness of the cover 21, the cover 21 and the lower shell 222 can be flush on both the inner and outer sides.

[0068] In an optional embodiment, if Figure 7 As shown, the first positioning protrusion 2221 is formed on the inner surface of the lower shell 222 and protrudes toward the window 220. At this time, the first positioning protrusion 2221 does not occupy the depth of the window 220 in the thickness direction. Therefore, the cover 21 does not need to be thinned corresponding to the first positioning protrusion 2221 to ensure that it is flush with the lower shell 222.

[0069] Furthermore, the provision of the first positioning protrusion 2221 actually thickens the lower shell 222 , thereby ensuring the strength of at least the portion of the lower shell 222 surrounding the window 220 .

[0070] In one embodiment, please refer to Figure 8 As shown, the cover 21 is provided with at least one second positioning protrusion 211 that protrudes toward the window 220. The second positioning protrusion 211 is configured to abut against the inner side surface of the lower shell 222 (the surface facing the upper shell 221). The abutment of the second positioning protrusion 211 against the inner side surface of the lower shell 222 ensures the positioning of the cover 21 and the lower shell 222 in the thickness direction, which will not be further described.

[0071] In an alternative embodiment, see Figure 8As shown, the second positioning protrusion 211 is provided on the inner surface of the cover 21 and protrudes relative to the cover 21 toward the lower shell 222. The purpose of this arrangement is that the second positioning protrusion 211 does not occupy the thickness of the cover 21 in the thickness direction, and therefore, the lower shell 222 does not need to be thinned corresponding to the second positioning protrusion 211.

[0072] Furthermore, the provision of the second positioning protrusion 211 actually thickens the cover 21 , thereby ensuring the strength of at least the edge region of the cover 21 .

[0073] In an optional embodiment, the first positioning protrusion 2221 and the second positioning protrusion 211 are provided simultaneously in the interchangeable power bank 100. This allows the cover 21 and the lower shell 222 to constrain each other in the thickness direction, ensuring that the cover 21 cannot separate from the lower shell 222 in the thickness direction and will not sink relative to the lower shell 222 due to external forces.

[0074] Of course, it can be understood that at this time, since the cover body 21 and the lower shell 222 restrict each other in the thickness direction, the cover body 21 is suitable for being configured to be completely separated from the lower shell 222 in the second position, that is, at this time, the cover body 21 cannot rotate relative to the lower shell 222.

[0075] For the aforementioned situation where the cover body 21 and the lower shell 222 are rotatably connected, it is optional to only provide the above-mentioned first positioning protrusion 2221 .

[0076] In more optional embodiments, it is also possible to choose to provide only the second positioning protrusion 211 .

[0077] See also Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, in one embodiment, a plurality of first positioning protrusions 2221 are provided on the lower shell 222, and at least one second positioning protrusion 211 is located between two adjacent first positioning protrusions 2221; or, a plurality of second positioning protrusions 211 are provided on the cover body 21, and at least one first positioning protrusion 2221 is located between adjacent second positioning protrusions 211; or, both the first positioning protrusion 2221 and the second positioning protrusion 211 may be multiple, and at least some of the first positioning protrusions 2221 and at least some of the second positioning protrusions 211 are arranged alternately.

[0078] See also Figure 5As shown, in one embodiment, the interchangeable power bank 100 further includes a switch 6, which is disposed in the inner cavity and electrically connected to the circuit board 4. The switch 6 may be optionally located on a surface of the circuit board 4 facing the cover 21. The switch 6 is used to connect or disconnect the electrical connection between each connection area and the circuit board 4. This arrangement is intended to ensure that when the connection area needs to be repaired or disassembled, the connection between the circuit board 4 and the power cord 5 can be temporarily disconnected by operating the switch 6 to ensure safe operation, especially when the battery cell assembly 3 still has some power.

[0079] In an optional embodiment, the switch element 6 is a mechanical switch, which has a third position and a fourth position on the circuit board 4. In the third position, the route between each connection area and the circuit board 4 is in an on state, allowing current to pass through. In the fourth position, the route between each connection area and the circuit board 4 is in a disconnected state, and current cannot pass through.

[0080] In other optional embodiments, the switch element 6 may have other forms, which will not be described one by one.

[0081] Please refer to Figure 2 、 Figure 4 and Figure 5 As shown, in one embodiment, the interchangeable power bank 100 further includes a power key 8, which is provided on the housing 2 and electrically connected to the circuit board 4. The power key 8 is used to generally cut off the electrical connection between the battery cell assembly 3 and other structures.

[0082] Finally, an embodiment of the present application provides a shared charging device (not shown), which includes a device body and one or more interchangeable power banks 100 as described in the above embodiments. The device body can be in any form. Interchangeable power banks 100 are available for users to rent for a fee.

[0083] In this shared charging device, the interchangeable power bank 100 allows merchants to repair or replace the power cord 5 by themselves, without having to return the entire power bank to the manufacturer for repair or scrapping the entire power bank, thus saving users material costs, repair time, and repair costs.

[0084] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
