Description

Technical Field

[0001] This application belongs to the field of mobile charging equipment technology, and particularly relates to a wired charging mobile power supply. Background Technology

[0002] The ever-evolving mobile smart devices, such as smartphones, tablets, and wearable devices, can meet user needs in business and personal communication, photography, and computing. However, in daily use, these devices are often limited by battery capacity and the inability to find a charging source promptly, leading to inconvenience. Therefore, users typically carry a power bank to charge their devices and ensure timely battery life.

[0003] Most portable power banks on the market use wired charging, which comes with a charging cable. To use them, one end of the charging cable is connected to the power bank, and the other end is connected to the mobile smart device being charged. This means that when users go out, they need to carry both the power bank and the charging cable. The charging cable needs to be stored with the power bank, otherwise it is easily lost. Without the charging cable, the mobile smart device cannot be charged.

[0004] It is evident that existing wired power banks require a charging cable for connection, which is inconvenient to store and affects usability. Summary of the Invention

[0005] The purpose of this application is to provide a portable power bank to solve the technical problem that the charging cable equipped on the existing portable power bank is not conducive to storage and carrying.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, embodiments of this application provide a portable power bank, including a main body and a charging cable.

[0008] The main body includes a housing and a main control board and a battery disposed inside the housing, the main control board being electrically connected to the battery; the housing has a socket for fixing the charging cable;

[0009] The charging cable includes a fixed end and a free end. The fixed end is fixed to the housing and electrically connected to the main control board inside the housing. The free end has a connector, which is detachably mounted on the socket of the housing.

[0010] The housing also includes a locking mechanism for locking the connector. The locking mechanism includes a button, a fastener, and a first elastic element connected to each other. The first elastic element is used to drive the fastener to fasten onto the connector. The button is used to drive the fastener to move away from the connector under external force to release the lock.

[0011] Therefore, when stored, the free end of the charging cable can be inserted into the socket of the casing and fixed in place by the locking mechanism, forming a ring structure on the power bank. This facilitates securing the cable to handbags and backpacks for easy storage and portability. In use, pressing the button unlocks the connector, allowing the charging cable to be removed from the power bank and connected to the desired mobile device.

[0012] In one embodiment, the housing has a fixing hole, and the fixing end of the charging cable has a buckle. The buckle is inside the housing and engages with the fixing hole on the housing, thereby fixing the fixing end of the charging cable to the housing and preventing it from coming out.

[0013] In one embodiment, the outer periphery of the housing is provided with multiple charging ports, all of which are electrically connected to the main control board, so that by connecting a data cable to the charging port, the data cable can be connected to a power source to achieve charging connection to the power bank.

[0014] Secondly, embodiments of this application also provide another mobile power supply, including a main body and a charging cable.

[0015] The main body includes a housing, on which a charging interface is provided, and inside the housing are a main control board and a battery. The charging interface and the battery are both electrically connected to the main control board. The housing has at least two sockets for fixing the charging cable.

[0016] The charging cable has connectors at both ends, and the connectors at both ends are detachably mounted on the socket of the housing.

[0017] The housing also includes two sets of locking mechanisms for locking the connector. Each set of locking mechanisms includes a button, a fastener, and a first elastic element connected to each other. The first elastic element is used to drive the fastener to fasten onto the connector. The button is used to drive the fastener to move away from the connector under external force to release the lock.

[0018] Therefore, when stored, both ends of the charging cable can be secured to the two ports on the casing using a locking mechanism. This creates a loop structure around the power bank, making it easy to attach to handbags and backpacks for convenient storage and portability. In use, operate the buttons on both sides of the casing to unlock both ends of the charging cable, thus detaching it from the power bank. Then, connect one end of the charging cable to the power bank's charging port, and the other end to the mobile smart device to be charged.

[0019] In one embodiment, both ports on the housing are located on the same side wall of the housing. This helps to reduce the span of the charging cable on the power bank, so that when the power bank is hung on a handbag or backpack via the charging cable, it can stay close to the handbag or backpack, preventing the power bank from drooping out of the handbag or backpack and being easily damaged by external objects.

[0020] In one embodiment, the two ports on the housing are respectively located on two opposite or adjacent side walls of the housing. This allows for an increase in the span of the charging cable on the power bank, and the length of the charging cable can be used to adjust the position of the power bank on a handbag or backpack, thereby improving the flexibility of storage.

[0021] The locking mechanism is further improved by providing a latching groove on the connector head. The latching member includes a connecting part and a hook disposed on the connecting part. The connecting part is connected to the button and the first elastic member, and the hook is used to latch onto the latching groove on the connector head. Thus, the latching groove on the connector head serves both to engage with the latching member and to provide directional marking, thereby improving installation accuracy.

[0022] In one embodiment, the locking mechanism further includes a guide tube into which the connector extends. The guide tube communicates with a socket on the housing and has a through hole for the hook to pass through. The hook engages with a groove on the connector inside the guide tube. Thus, the guide tube corrects the orientation of the connector inside the housing, ensuring that the hook on the fastening element accurately engages with the groove on the connector, improving the securing effect of the connector.

[0023] In one embodiment, the housing has a through hole for mounting the button, and the locking mechanism further includes a fixing seat opposite to the through hole. The through hole on the housing, the button, the connecting portion of the fastener, the first elastic element, and the fixing seat are coaxially aligned. In this way, the force between the components in the locking mechanism is transmitted along a single axis, reducing the risk of off-center loading or jamming, improving the smoothness of the button pressing and reset process, and extending the service life of the components.

[0024] Another improvement to the locking mechanism is the inclusion of an ejection assembly for ejecting the connector. This ejection assembly includes a retaining ring and a second elastic member. The connecting portion of the fastener passes through the retaining ring and is movable within it. The second elastic member is disposed on the retaining ring and faces the insertion port on the housing. An extension end of the second elastic member has a cap for abutting against the connector. Thus, during unlocking, the connector can be quickly and reliably ejected without manual pulling, making it convenient to use.

[0025] The beneficial effects of the portable power bank provided in this application are as follows: Compared with the prior art, the portable power bank in this application embodiment is provided with a locking mechanism for fixing the end of the charging cable, so that the charging cable can be fixedly connected to the portable power bank, thereby enabling the charging cable and the portable power bank to be stored and carried together, effectively improving the problem that the charging cable provided on the traditional portable hard drive enclosure is not easy to store.

[0026] In addition, when both ends of the charging cable are fixedly connected to the power bank, the charging cable forms a loop structure on the power bank, thus allowing the charging cable to be used as a "lanyard" on the power bank. This allows the power bank to be fixed to a handbag or backpack for easy carrying, effectively improving its aesthetics and style. Attached Figure Description

[0050] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0051] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0052] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0054] Traditional wired power banks typically require a separate charging cable. To use one, connect one end of the cable to the power bank and the other end to the device. This means that when out and about, users need to carry both the power bank and the charging cable. Since the power bank and charging cable are two separate components, the charging cable must be stored together with the power bank to prevent loss. Without the charging cable, charging will be impossible.

[0055] In related technologies, there is a structure that integrates a charging cable with a power bank. This structure has one end of the charging cable fixed to the power bank, while the other end remains free for connecting to the mobile smart device being charged. However, the free end of this charging cable lacks protection, making it prone to short circuits when not in use (e.g., when in contact with other metal parts), thus affecting safety.

[0056] Therefore, this application provides a novel portable power bank, which redesigns the structure of the charging cable used on the power bank, allowing the charging cable to be securely fixed to the power bank, so that the power bank and charging cable can be stored and carried together; at the same time, it effectively improves the problem that the free end of the charging cable is prone to short circuits when not in use. A detailed description will now be provided.

[0057] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The power bank provided in this application embodiment includes at least a power bank body 1 and a charging cable 2 that is equipped with the body 1.

[0058] The main body 1 includes a housing 11, a main control board 12 disposed inside the housing 11, and a battery 13. The main control board 12 is electrically connected to the battery 13. In this embodiment, as... Figure 3 As shown, the main control board 12 is preferably located near the top of the inner cavity of the housing 11, and the battery 13 is preferably located near the bottom of the inner cavity of the housing 11. A heat insulation space is formed between the main control board 12 and the battery 13 to avoid the heat generated by the battery 13 during operation from affecting the main control board 12 and effectively ensure the stability of operation.

[0059] Please refer to the following: Figure 2 and Figure 3 The housing 11 has a socket 10 for fixing the charging cable 2. The shape of the socket 10 is preferably matched with the shape of the end of the charging cable 2 so that the end of the charging cable 2 can extend into the interior of the housing 11 from the socket 10.

[0060] The charging cable 2 has a connector 21 at both ends or at least one end for connecting to a mobile smart device to be charged. The connector 21 is detachably mounted on the socket 10 of the housing 11.

[0061] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The housing 11 of the main body 1 also includes a locking mechanism 100, which is used to lock the connector 21 of the charging cable 2 inserted into the socket 10, thereby preventing the end of the charging cable 2 from easily coming out.

[0062] Specifically, the locking mechanism 100 includes a button 3, a fastener 4, and a first elastic element 5, which are connected sequentially. The first elastic element 5 can preferably be a spring. One end of the first elastic element 5 can be fixed to the inner wall of the housing 11, or a separate structure can be provided to fix the end of the first elastic element 5; no specific limitation is made here. The other end of the first elastic element 5 is connected to the fastener 4. The first elastic element 5 is used to drive the fastener 4 to fasten onto the connector 21.

[0063] Thus, under the force of the first elastic member 5, the fastening member 4 can remain fastened to the connector 21 that extends into the housing 11 from the insertion port 10, thereby locking the connector 21. This can be understood as the fastening member 4 being able to fasten and fix the end or specific part (such as a specially provided fastening part on the connector 21) of the connector 21, thereby locking the connector 21.

[0064] Button 3 is used to drive the fastener 4 to retract and move the first elastic member 5 under external force (such as when pressed by a human hand), so that the fastener 4 is removed from the connector 21, thereby unlocking the connector 21 and allowing the connector 21 to be pulled out naturally for use.

[0065] Compared with the prior art, the power bank provided in this application embodiment has a locking mechanism 100 for fixing the end of the charging cable 2, so that the charging cable 2 can be fixedly connected to the power bank, thereby enabling the charging cable 2 and the power bank to be stored and carried together, effectively improving the problem that the charging cable 2 provided on traditional mobile hard drive enclosures is not easy to store.

[0066] Compared to the aforementioned related technologies where the charging cable 2 is integrally connected to the power bank, the free end of the charging cable 2 in the related technologies is not effectively fixed, making it easy for the free end of the charging cable 2 to come into contact with metal parts and cause a short circuit when not in operation. Therefore, in the power bank of this embodiment, the end of the charging cable 2 can extend into the interior of the main body 1 from the socket 10 on the housing 11. The housing 11 covers and protects the end of the charging cable 2, and a locking mechanism 100 is used to fix it, effectively preventing short circuits at the connector 21 at the end of the charging cable 2, thereby improving the protection effect.

[0067] In addition, when both ends of the charging cable 2 are fixedly connected to the power bank, the charging cable 2 forms a ring structure on the power bank, so that the charging cable 2 can be used as a "lanyard" on the power bank, allowing the power bank to be fixed on a handbag or backpack for easy carrying, which effectively improves the aesthetics and fashion sense.

[0068] The fixed connection structure of the charging cable 2 on the power bank in this application embodiment includes, but is not limited to, the following forms:

[0069] Example 1

[0070] In one embodiment of this application, please refer to the following: Figure 3 , Figure 4 and Figure 5The charging cable 2 has a fixed end 22 and a free end 23 at both ends. The fixed end 22 of the charging cable 2 is fixed to the housing 11 and electrically connected to the main control board 12 inside the housing 11. The free end 23 of the charging cable 2 has a connector 21, which is used to connect to the mobile smart device to be charged. The connector 21 can preferably be a USB, TYPE-C or other connector, which is beneficial for compatibility with the interface of the mobile smart device to be charged.

[0071] The connector 21 on the free end 23 of the charging cable 2 is detachably mounted on the socket 10 of the housing 11. The fastener 4 of the locking mechanism 100 can be fastened to the connector 21 that extends into the socket 10, and under the force of the first elastic member 5, it keeps the connector 21 fastened and locked, effectively preventing the connector 21 from coming out naturally and ensuring the fixing effect of the connector 21.

[0072] Thus, when stored, the free end 23 of the charging cable 2 is inserted into the socket 10 of the housing 11 and fixed by the locking mechanism 100, so that the charging cable 2 forms a ring structure on the power bank, which is conducive to fixing it on handbags and backpacks, making it convenient to store and carry.

[0073] In use, the user presses button 3 on the locking mechanism 100 to cause the latch 4 to move away from the connector 21, thus unlocking the device. At this time, the user can remove the connector 21 of the charging cable 2 from the power bank and connect it to the mobile smart device to be charged.

[0074] Regarding the fixing structure of the fixed end 22 of the charging cable 2 on the housing 11, please refer to one embodiment of this application. Figure 4 and Figure 5 The housing 11 has a fixing hole, and the fixing end 22 of the charging cable 2 has a buckle 24. The buckle 24 is inside the housing 11 and is engaged with the fixing hole 14 on the housing 11, thereby fixing the fixing end 22 of the charging cable 2 to the housing 11 and preventing it from coming out.

[0075] Thus, one end of the charging cable 2 is fixedly connected to the housing 11, and the other end serves as the free end 23, which can be connected to the mobile smart device to be charged during use; or, when storing, the free end 23 is installed on the socket 10 of the housing 11 and fixed by the locking mechanism 100, which facilitates storage and protects the connector 21 on the free end 23 of the charging cable 2.

[0076] For the structure on the housing 11, please refer to the embodiments of this application. Figure 3 , Figure 4 and Figure 5The outer periphery of the housing 11 is also provided with multiple charging ports 15, which are electrically connected to the main control board 12 so that by connecting a data cable (not shown in the figure) to the charging port 15, the data cable can be connected to the power supply to achieve charging connection to the power bank.

[0077] In this embodiment, the housing 11 has at least two charging ports 15, both of which are electrically connected to the main control board 12. The charging ports 15 are preferably USB, Type-C, or similar interfaces, which facilitates the selection of data cables with the appropriate interface for charging connection, effectively improving usability.

[0078] Example 2

[0079] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 6 , Figure 7 and Figure 8 In this embodiment of the application, a mobile power bank is provided with at least one charging interface 15 on the housing 11. The housing 11 contains a main control board 12 and a battery 13. Both the charging interface 15 and the battery 13 are electrically connected to the main control board 12. The housing 11 has at least two sockets 10 for fixing the two ends of the charging cable 2.

[0080] Both ends of the charging cable 2 have connectors 21, and the connectors 21 at both ends of the charging cable 2 are detachably mounted on the sockets 10 of the housing 11.

[0081] The housing 11 includes two sets of locking mechanisms 100. Please refer to... Figure 4 As shown, the fastening member 4 in each locking mechanism 100 can fasten and fix the connector 21 that extends into the socket 10, and maintain the fastening and locking of the connector 21 under the action of the first elastic member 5, thereby preventing the connector 21 from coming out naturally and ensuring the fixing effect of the connector 21.

[0082] Therefore, when stored, both ends of the charging cable 2 can be fixed to the two ports 10 of the housing 11 by the locking mechanism 100. This allows the charging cable 2 to form a loop structure on the power bank, which is convenient for fixing to handbags and backpacks, making it easy to store and carry.

[0083] In use, operate the button 3 of the locking mechanism 100 to unlock the connectors 21 at both ends of the charging cable 2, thereby removing the charging cable 2 from the power bank; then, connect one end connector 21 of the charging cable 2 to the charging port 15 of the power bank, and connect the other end of the charging cable 2 to the mobile smart device to be charged, so as to charge the mobile smart device.

[0084] Regarding the arrangement of the portion on the housing 11 for mounting the end of the charging cable 2, in the embodiments of this application, both ports 10 on the housing 11 are located on the same side wall surface of the housing 11. Please refer to the following: Figure 6 , Figure 7 and Figure 8 The power bank in this embodiment adopts a flat rectangular structure. Two sockets 10 are opened on the top wall of the housing 11, and locking mechanisms 100 are respectively provided in the space corresponding to the sockets 10 inside the housing 11, so that the two ends of the charging cable 2 can be fixed by the locking mechanisms 100 after being inserted into the sockets 10, preventing them from coming out.

[0085] This helps to reduce the span of the charging cable 2 on the power bank, so that when the power bank is hung on the handbag or backpack via the charging cable 2, the power bank can stay close to the handbag or backpack, preventing the power bank from drooping out of the handbag or backpack and being easily damaged by collisions with external objects.

[0086] In other embodiments of this application (not shown in the figures), the two ports 10 on the housing 11 can be respectively opened on two opposite side walls of the housing 11; or, they can be opened on two adjacent side walls of the housing 11, and locking mechanisms 100 are respectively provided in the space corresponding to the ports 10 inside the housing 11, so as to fix the connectors 21 on the charging cable 2 inserted into the housing 11 from the ports 10.

[0087] This allows for a greater span of the charging cable 2 across the power bank, and the length of the charging cable 2 can be used to adjust the position of the power bank on a handbag or backpack. For example, if the charging cable 2 is too long, it can be shortened by winding it, thereby improving the flexibility of storage.

[0088] Regarding the mating structure between the locking mechanism 100 and the connector 21 on the charging cable 2, please refer to one embodiment of this application. Figure 9 and Figure 10 The connector 21 of the charging cable 2 is provided with a buckle groove 211, which is preferably a linear groove opened on the outer periphery of the connector 21.

[0089] The fastener 4 includes a connecting part 41 and a hook 42 disposed on the connecting part 41. The connecting part 41 is connected to the button 3 and the first elastic member 5. The hook 42 is used to fasten onto the fastening groove 211 of the connector 21.

[0090] In this embodiment, the connecting portion 41 of the fastener 4 serves as a connector for connecting and engaging with the button 3 and the first elastic member 5 respectively. The hook 42 extends outward from the connecting portion 41, and the shape of the hook on the hook 42 can preferably match the shape of the groove 211 on the connector 21 so as to fasten and fix them together.

[0091] Thus, the slot 211 on the connector 21 engages with the hook 42 on the fastener 4, securing the connector 21 in place and preventing it from easily coming off. The slot 211 on the connector 21 serves both as an engagement point with the fastener 4 and as a directional marker, providing a reference point during installation so that the user can accurately install the connector 21 onto the power bank, improving installation accuracy.

[0092] In one embodiment of this application, please refer to the following: Figure 9 , Figure 10 and Figure 11 The locking mechanism 100 on the housing 11 also includes a guide tube 6 into which the connector 21 extends. The guide tube 6 is connected to the insertion port 10 on the housing 11. It can be understood here that the guide tube 6 is integrally connected to the inner wall of the housing 11, and the insertion port 10 is located within the range of the guide tube 6. When the connector 21 extends into the housing 11 from the insertion port 10, it will simultaneously extend into the guide tube 6.

[0093] The guide cylinder 6 has a through hole 61, the position of which corresponds to the position of the latching groove 211 on the connector 21 that extends into the guide cylinder 6.

[0094] The hook 42 on the fastener 4 passes through the through hole 61 into the interior of the guide tube 6. The hook 42 can engage with the fastening groove 211 on the connector 21 inside the guide tube 6 to achieve fastening and fixing of the connector 21.

[0095] In this way, the guide tube 6 is used to correct the posture of the connector 21 inside the housing 11 so that the hook 42 on the fastener 4 can be accurately fastened to the fastening groove 211 of the connector 21, thereby improving the fixing effect of the connector 21.

[0096] In one embodiment of this application, please refer to the following: Figure 10 and Figure 11 The housing 11 has a through hole 16 for setting the button 3. The locking mechanism 100 on the housing 11 also includes a fixing seat 7 that is disposed opposite to the through hole 16. The through hole 16, button 3, connecting part 41 of fastener 4, first elastic member 5 and fixing seat 7 on the housing 11 are coaxially aligned.

[0097] In this embodiment, the fixing base 7 has a reinforcing plate 71 that extends to the inner wall of the housing 11 where the through hole 16 is located, thereby improving the structural strength of the fixing base 7. The fixing base 7 is provided with a mounting groove so that one end of the first elastic member 5 can be fixed in the mounting groove of the fixing base 7, and the other end of the first elastic member 5 abuts against or is connected to the connecting part 41 on the fastener 4.

[0098] When a person presses button 3, button 3 drives the fastener 4 and the first elastic element 5 to retract towards the fixed seat 7, so that the fastener 4 can be removed from the connector 21 to achieve the unlocking operation. When the force of the hand is removed, the first elastic element 5 returns to its original state and applies a force in the direction of the through hole 16 to drive the fastener 4 and button 3 to reset.

[0099] In this way, the force between the various components in the locking mechanism 100 is transmitted along a single axis, reducing the risk of off-center loading or jamming, improving the smoothness of the button 3 pressing and reset process, and helping to extend the service life of the components.

[0100] In practical applications, unlocking the connector 21 on the charging cable 2 requires pressing button 3 with one hand to remove the fastener 4 from the connector 21, thus releasing the lock on the connector 21; the other hand then pulls the connector 21 off the housing 11. If the two hands are not coordinated well, such as releasing button 3 too quickly, the fastener 4 will be driven to reset rapidly by the first elastic element 5, and the connector 21 that has not been pulled out in time will be locked quickly, affecting the smoothness of the operation.

[0101] Therefore, another improvement is made to the structure of the locking mechanism 100, which can be seen in another embodiment of this application. Figure 10 , Figure 11 and Figure 12 The locking mechanism 100 on the housing 11 also includes an ejection assembly 8 for ejecting the connector 21. The ejection assembly 8 includes a retaining ring 81 and a second elastic member 82. The connecting portion 41 of the fastener 4 passes through the retaining ring 81 and can be moved in the retaining ring 81 by the button 3 or the first elastic member 5.

[0102] The second elastic element 82 can preferably be a spring. The second elastic element 82 is disposed on the fixing ring 81 and is disposed opposite to the insertion port 10 on the housing 11. The second elastic element 82 extends toward the insertion port 10, and a top cap 821 for abutting against the connector 21 is provided on the extended end of the second elastic element 82.

[0103] When the connector 21 of the charging cable 2 extends into the interior of the housing 11 from the socket 10 of the housing 11, it can preferably extend into the interior of the housing 11 along the guide tube 6 and abut against the top cap 821 to drive the second elastic member 82 to retract; at the same time, the buckle groove 211 on the connector 21 is fastened and fixed with the buckle hook 42 of the fastener 4 to lock the connector 21.

[0104] When a person operates button 3 to unlock the device, the hook 42 on the fastener 4 moves away from the slot 211 of the connector 21 to release the connector 21. The connector 21 is then ejected from the housing 11 by the second elastic member 82, thereby unlocking the connector 21.

[0105] Therefore, during the unlocking operation, the connector 21 can be quickly and reliably ejected without manual pulling, making it convenient to use.

[0106] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
