In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0023] This application provides a mobile power supply 100 with a stable cable management system. Please refer to [link / reference]. Figure 1 and Figure 2 The power bank 100 includes a housing 10, a power assembly 20, a wire 30, and a connector 40. The housing 10 is the exterior cover of the power bank 100, which forms the main appearance of the power bank 100 and provides structural support and physical cover for the internal components to prevent the ingress of foreign objects.

[0024] The power supply assembly 20 is located inside the housing 10 and is a structure within the power bank 100 used for power storage and conversion. Exemplarily, the power supply assembly 20 includes a circuit board 21 and a battery cell 22. The battery cell 22 is a device for converting chemical energy into electrical energy, and can be a pouch battery or a steel-cased battery. The circuit board 21 is electrically connected to the battery cell 22. The circuit board 21 is used to transform the externally input current so that it can be used to charge the battery cell 22, and to vary the output current of the battery cell 22 so that it can be used in electrical devices, such as mobile phones, cameras, and laptops. In some embodiments, the circuit board 21 also has overload protection or automatic power-off functions for overcharge.

[0025] Please see Figure 2 and Figure 3 The surface of the housing 10 is recessed inward to define a clearance channel 10b extending along a first direction. The housing 10 has a first opening 10a-1, which is located at one end of the clearance channel 10b and connects to the clearance channel 10b. The first direction is not specifically limited. For example, taking the mobile power supply 100 as a prism, the first direction can be along the height direction of the prism.

[0026] Please see Figure 3 The connector 40 is used to connect electrical devices. It is understood that the electrical devices have an interface used to establish a physical connection with the connector 40. The interface type is not limited; it can be USB-A (Universal Serial Bus), USB-C, or a Lightning interface, etc. One end of the wire 30 extends into the housing 10 and connects to the power supply assembly 20, while the other end extends out of the housing 10 and connects to the connector 40. In this way, power can be transmitted between the power supply assembly 20 and the electrical devices through the wire 30 and the connector. The transmission direction is not limited; it can be the power supply assembly 20 supplying power to the electrical devices, or the electrical devices supplying power to the power supply assembly 20.

[0027] The power bank 100 includes a cable 30 and a connector 40, so that the power bank 100 can be taken out at any time to connect to the device for use. Users do not need to carry a separate charging cable, avoiding the embarrassment of forgetting to bring the charging cable and improving the convenience of the power bank 100. One end of the cable 30 extends into the housing 10, which simplifies the storage process.

[0028] Understandably, the wire 30 is flexible, can be easily deformed and does not easily generate rigid resistance. One end of the wire 30 that connects to the connector 40 is a free end, which can freely extend, retract and bend outside the housing 10 as the user pinches the connector 40.

[0029] Please see Figure 2 and Figure 3 The connector 40 can be accommodated within the clearance channel 10b through the first opening 10a-1. In other words, the first opening 10a-1 allows the connector 40 to pass through, and the connector 40 can be inserted into the clearance channel 10b along the first direction. This allows for the storage of the connector 40. The clearance channel 10b also protects the connector 40 and enhances the overall aesthetics of the power bank 100. With the connector 40 accommodated within the clearance channel 10b, the free end of the wire 30 can be secured. When the user stores the power bank 100 in a bag or pocket, the wire 30 is less likely to become tangled or knotted, making it easier to retrieve for future use.

[0030] Please see Figure 8 The connector 40 has a first limiting structure 41a. See also... Figure 5 and Figure 6 The power bank 100 also includes a limiting component 50, which is located inside the housing 10. The limiting component 50 includes a second limiting structure 51 that can move along a second direction. The first direction intersects with the second direction. For example, taking the power bank 100 as a prism, the second direction can be any direction perpendicular to the height direction, that is, the first direction is perpendicular to the second direction.

[0031] With the connector 40 housed within the clearance channel 10b, the second limiting structure 51 extends at least partially into the clearance channel 10b and engages with the first limiting structure 41a to limit the movement of the connector 40 in the first direction. The aforementioned engagement means that the first limiting structure 41a and the second limiting structure 51 can spatially interfere with each other, thereby restricting their movement. In this way, the limiting assembly 50 can fix the connector 40 inside the clearance channel 10b, preventing it from detaching and achieving both storage and fixation. This design is compact and provides good limiting effect.

[0032] It should be noted that the first limiting structure 41a can also move along the second direction toward the direction away from the interior of the clearance channel 10b, thereby releasing the lock on the connector 40, allowing the connector 40 to be removed, and the power supply 100 to be used.

[0033] Therefore, the portable power bank 100 provided in this application embodiment has a wire 30 and a connector 40 that can be connected to an electrical device, which is convenient for users. The connector 40 can be stored in the clearance channel 10b of the housing 10. The limiting component 50 fixes the free end of the wire 30 to prevent the wire 30 from getting tangled, making it easy to store. The portable power bank 100 is easy to carry and use.

[0034] In some embodiments, please refer to Figure 3 and Figure 4 The housing 10 has a second opening 10a-2, which is located on the periphery of the clearance channel 10b and connects to the clearance channel 10b. When the connector 40 is housed in the clearance channel 10b, the periphery of the connector 40 is exposed to the outside of the housing 10 through the second opening 10a-2. That is, the second opening 10a-2 connects the inside of the clearance channel 10b and the external environment of the housing 10.

[0035] In this embodiment, during the movement of the connector 40 within the clearance channel 10b, the second opening 10a-2 facilitates the user's observation or perception of the connector 40's specific position, improving tactile feedback. Furthermore, it allows the user to access the connector 40 within the clearance channel 10b from outside the housing 10 via the second opening 10a-2, thereby assisting the connector 40's movement along the first direction. For example, as... Figure 4 As shown, the outline of the second opening extends along the first direction.

[0036] It should be noted that in some embodiments, the width of the second opening 10a-2 perpendicular to the first direction is smaller than the maximum size of the connector 40, so that the connector 40 is difficult to dislodge from the second opening 10a-2.

[0037] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 8 The shell 10 includes a first shell wall 11 and a second shell wall 12 connected adjacent to each other. The shell 10 may also include other shell walls, which together form the shell 10 and define the internal space of the shell 10. It should be noted that the shell 10 may be a split structure, that is, some shell walls are assembled together with other shell walls.

[0038] The first opening 10a-1 is located on the first shell wall 11, and the second opening 10a-2 is located on the second shell wall 12, and the first opening 10a-1 and the second opening 10a-2 are connected. The above-mentioned connection means that the first opening 10a-1 and the second opening 10a-2 are connected at the corner of the first shell wall 11 and the second shell wall 12, and the first opening 10a-1 and the second opening 10a-2 are no longer independent and separate openings.

[0039] In this embodiment, on the one hand, while the plug 40 can pass through the first opening 10a-1, its periphery can also extend into the space surrounded by the second opening 10a-2 as the plug 40 moves along the first direction. That is to say, the periphery dimension of the plug 40 and the thickness of the second shell wall 12 can overlap. Therefore, the thickness of the structure around the clearance channel 10b can be designed to be smaller, which is beneficial to the portability of the power bank 100. On the other hand, when the user inserts the plug 40 along the first opening 10a-1, the accuracy requirement is relatively low, and it is relatively easy to insert, thus making it convenient for the user to store the plug 40.

[0040] In some embodiments, please refer to Figure 8 The first shell wall 11 also has a third opening 10a-3. One end of the wire 30 extends into the shell 10 through the first opening 10a-1 and connects to the power assembly 20. In this embodiment, the third opening 10a-3 and the first opening 10a-1 are located on the same shell wall (i.e., the first shell wall 11). With the connector 40 accommodated in the clearance channel 10b, both ends of the wire 30 pass through the first shell wall 11, thus the wire 30 can be used as a hanging rope. For example, the user can hang the wire 30 on a hook to store the power bank 100; or, the user can hold the wire 30 in their hand as a handle for the power bank 100 for easy carrying.

[0041] For example, in some embodiments, the center distance between the third opening 10a-3 and the first opening 10a-1 is no greater than 12 mm, so that when the connector 40 is accommodated in the clearance channel 10b, the wire 30 can form a more complete circle, with a greater degree of freedom in deformation. The center distance between the third opening 10a-3 and the first opening 10a-1 can be 12 mm, 11 mm, or 10 mm.

[0042] In some embodiments, please refer to Figure 7 and Figure 8 The power supply assembly 20 includes a circuit board 21 and a battery cell 22 that are electrically connected to each other. The circuit board 21 has at least one power supply interface 211, which provides an interface for the circuit board 21 to connect with other external devices. The power supply interface 211 can be an input port or an output port.

[0043] The first shell wall 11 also has at least one fourth opening 10a-4, through which at least one power supply interface 211 is exposed to the outside of the shell 10. The number of power supply interfaces 211 corresponds one-to-one with the number of fourth openings 10a-4, and the user can insert a connecting cable that matches the power supply interface 211 into the power supply interface 211 through the fourth opening 10a-4.

[0044] The number of power supply interfaces 211 can be one or more. For example, there can be two power supply interfaces 211, including one USB-A interface and one USB-C interface, to meet various user needs. Correspondingly, the number of fourth interfaces 10a-4 can also be one or more.

[0045] In this embodiment, the first opening 10a-1, the third opening 10a-3, and the fourth opening 10a-4 are all concentrated on the first shell wall 11, making it possible for the surfaces of the remaining shell walls to be continuous surfaces, reducing openings and improving the aesthetics of the power bank 100. When using the power bank 100, external wiring is less likely to interfere.

[0046] In some embodiments, please refer to Figure 9 The connector 40 includes a plug-in portion 42 and an operating portion 41. One end of the operating portion 41 is connected to the wire 30, and the other end is connected to the plug-in portion 42. The plug-in portion 42 is used to insert into the interface of the electrical device. Exemplarily, the surface of the operating portion 41 may be insulated and non-slip, allowing the user to grip it to align with the plug-in portion 42. The plug-in portion 42 may be a metal structure that establishes an electrical connection with the interface of the electrical device through internal metal contacts.

[0047] Please continue reading. Figure 3 and Figure 4The clearance channel 10b includes an expanding section 10b1 and a narrowing section 10b2 arranged along a first direction. It is understood that the average radial dimension of the expanding section 10b1 is greater than the average radial dimension of the narrowing section 10b2. The inner surface of the clearance channel 10b has a stepped structure, with the expanding section 10b1 and the narrowing section 10b2 located on opposite sides of the stepped structure. That is, the difference in radial dimensions between the expanding section 10b1 and the narrowing section 10b2 forms a step-like structure at their junction. When the connector 40 is accommodated within the clearance channel 10b, and the connector portion 42 is accommodated within the narrowing section 10b2, at least a portion of the operating portion 41 is located within the expanding section 10b1.

[0048] In this embodiment, the reduced diameter section 10b2 can provide physical protection for the plug part 42, and the stepped structure can limit the movement of the plug 40 along the first direction. During the process of storing the plug 40 into the clearance channel 10b, the user can know that the plug 40 has been stored in place by the resistance generated by the stepped structure limiting the movement of the plug 40, which facilitates the user's "quick plug" operation.

[0049] In embodiments where the housing 10 also has a second opening 10a-2, the second opening 10a-2 may be located on the circumferential side of the enlarged diameter section 10b1, that is, the circumference of the enlarged diameter section 10b1 communicates with the outside of the housing 10, such as... Figure 3 and Figure 4 As shown.

[0050] In some embodiments, please refer to Figure 5 and Figure 6 The limiting component 50 includes an elastic element 52 located inside the housing 10 and connected to the second limiting structure 51. The elastic element 52 is used to undergo elastic deformation to drive the second limiting structure 51 to move along a second direction toward the direction of extending into the clearance channel 10b. The elastic element 52 may be a spring or an elastic sheet, etc.

[0051] When the elastic element 52 undergoes elastic deformation, it accumulates elastic potential energy, causing the second limiting structure 51 connected to it to tend to move towards extending into the clearance channel 10b. However, if the reverse external force acting on the second limiting structure 51 is too strong, it can retract. Thus, during the process of the connector 40 being housed within the clearance channel 10b, when the first limiting structure 41a and the second limiting structure 51 meet the positional conditions for stop engagement, the second limiting structure 51 automatically extends, completing the fixation of the connector 40. Throughout the process, the user operation is simple and convenient, facilitating the rapid storage of the connector 40.

[0052] In some embodiments, please refer to Figure 7 and Figure 8The surface of the connector 40 is recessed inward to form a groove to define the first limiting structure 41a. The second limiting structure 51 includes a protrusion 511. When the connector 40 is accommodated in the clearance channel 10b, the protrusion 511 extends into the groove. In this way, the second limiting structure 51 and the first limiting structure 41a complete the stop engagement.

[0053] For example, the protrusion 511 has a rounded corner on the side closest to the first opening 10a-1 along the first direction. Thus, as the connector 40 moves along the first direction from the first opening 10a-1, the rounded corner of the protrusion 511 changes the direction of force transmission when it contacts the connector 40. The connector 40 can then compress and retract the protrusion 511 into the housing 10, thereby preventing the connector 40 from moving. Until the groove of the connector 40 reaches the position matching the protrusion 511, the second limiting structure 51 moves under the action of the elastic member 52, allowing the protrusion 511 to extend into the groove, thus forming a stop fit. Throughout the process, the movement of the connector 40 is not easily jammed and the movement is smooth.

[0054] For example, the protrusion 511 is planar on the side away from the first opening 10a-1 along the first direction. Thus, when the connector 40 is housed in the clearance channel 10b, even if the connector 40 tends to come out under the action of external force (e.g., the pulling force generated by suspending the mobile power supply 100 through the wire 30), the inner surface of the groove is unlikely to press the protrusion 511 in the direction of contraction. Therefore, the protrusion 511 and the groove can form a stable stop fit, reducing the probability of the connector 40 coming out.

[0055] In some embodiments, please refer to Figure 3 and Figure 4 The housing 10 has a groove 10c, and the second limiting structure 51 also includes a lever portion 512. The lever portion 512 is connected to the protrusion 511, and a portion of the lever portion 512 extends out from the inside of the housing 10 through the groove 10c. The lever portion 512 can move in the groove 10c along the second direction. The user can contact the lever portion 512 on the surface of the housing 10 with the groove 10c, thereby pressing and rubbing it with his / her fingers or flicking the lever portion 512 with his / her fingers to apply force to the second limiting structure 51, causing it to move in the second direction and drive the protrusion 511 to disengage from the groove, releasing the stop engagement between the first limiting structure 41a and the second limiting structure 51. The connector 40 can then be removed from the clearance channel 10b for the user's use.

[0056] In some embodiments, please refer to Figure 6 and Figure 7The lever portion 512 includes a lever 5121 and a ring portion 5122. The lever 5121 extends through the groove 10c, and the ring portion 5122 connects the lever 5121 and the protrusion 511, so that the user can contact the lever 5121 on the surface of the housing 10 with the groove 10c.

[0057] The ring portion 5122 has a guide hole 5122b and a mounting hole 5122a, both of which extend along the second direction and are arranged side by side. Figure 7 As shown, the ring portion 5122 is in the form of multiple rings, and the guide holes 5122b are spaced apart on the periphery of the mounting holes 5122a.

[0058] The mounting hole 5122a is a blind hole. The elastic member 52 is located inside the mounting hole 5122a, with one end of the elastic member 52 abutting against the blind end of the mounting hole 5122a, and the other end connected to the housing 10. Exemplarily, a stop piece 13 is formed inside the housing 10 to abut against the other end of the elastic member 52. Figure 6 As shown. The mounting hole 5122a is used to accommodate and support the elastic element 52, which can regulate the deformation direction of the elastic element 52 and prevent it from twisting and deforming during deformation.

[0059] The inner surface of the housing 10 also protrudes to form a guide post 121, and a guide hole 5122b is fitted onto the guide post 121, with both engaging to prevent rotation. It can be understood that the guide post 121 also extends along the second direction. Thus, during the movement of the second limiting structure 51 along the second direction, the guide hole 5122b can move along the extending direction of the guide post 121. The engagement between the guide hole 5122b and the guide post 121 serves to guide and support the second limiting structure 51.

[0060] The aforementioned anti-rotation fit between the guide hole 5122b and the guide post 121 means that the guide hole 5122b and the guide post 121 are unlikely to rotate relative to each other. This prevents the lever 5121 from wobbling during movement and optimizes the user's operating feel. The guide hole 5122b can be any shape other than a perfect circle, such as... Figure 7 The guide post 121 is either an annular or polygonal shape, and its cross-sectional shape is either an annular or polygonal shape that matches the guide hole 5122b.
