Description

Technical Field

[0001] This utility model relates to the field of mobile power supplies, and more particularly to a power bank. Background Technology

[0002] With the widespread use of portable electronic devices such as smartphones and tablets, power banks have become an essential accessory for daily travel. However, when using traditional power banks to charge electronic devices, users typically need to hold both the power bank and the device with one hand, or place the power bank on a flat surface such as a table. When users are standing, walking, or in environments without a flat surface, the power bank is prone to slipping from their hands, causing charging interruptions or even damage to both the power bank and the electronic device, resulting in a poor user experience.

[0003] To address the aforementioned issues, existing technologies have incorporated power banks with ring clips, elastic straps, or suction cups. However, these structures suffer from the following drawbacks:

[0004] 1. The ring buckle or elastic strap cannot be fully stored when not in use, making the power bank look awkward and affecting its portability.

[0005] 2. Suction cups are prone to failure after prolonged use and have requirements on the material of the phone case, resulting in poor versatility.

[0006] 3. The above structures can usually only achieve the functions of preventing falling off or providing a support, and cannot simultaneously achieve storage and multi-functionality.

[0007] Therefore, developing a compact, easy-to-store, and effectively preventable power bank from falling off has become an urgent technical problem to be solved. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a power bank that is compact in structure, easy to store, and can effectively prevent it from falling off.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a power bank, comprising...

[0011] A flexible strip has a first hinge at one end and a second hinge at the other end, the first hinge being rotatably mounted on the outer wall of the housing.

[0012] A folding component has a third hinge at one end and a fourth hinge at the other end. The third hinge is rotatably connected to the second hinge, and the fourth hinge is rotatably mounted on the outer wall of the housing.

[0013] When the third hinge part separates from the side wall of the housing, a closed-loop gap is formed between the housing, the flexible strip and the folding member, allowing a hand to pass through;

[0014] When the third hinge portion contacts the side wall of the housing, the flexible strip covers the folding member.

[0015] Furthermore, the outer side wall of the housing is provided with a receiving groove for receiving the folding component.

[0016] Furthermore, the outer wall of the housing is also provided with a pick-and-place slot that communicates with the receiving slot.

[0017] Furthermore, the outer wall of the housing is also provided with a support frame, one end of which is a hinged end and the other end is a support end; the hinged end is rotatably mounted on the housing, and the support end is used to contact external components.

[0018] Furthermore, the fourth hinge is rotatably mounted on the support end of the support frame, and when the support end contacts the external component, one side wall of the folding member is in contact with the contact surface of the external component.

[0019] Furthermore, the folding member is provided with a damping layer, which is used to fit the contact surface with the external component.

[0020] Furthermore, the flexible strip is made of silicone.

[0021] Furthermore, the flexible strip has perforated holes.

[0022] Furthermore, the number of the perforated holes is multiple.

[0023] Furthermore, the folding member is provided with a first magnetic attraction member, and the housing is provided with a second magnetic attraction member. When the third hinge part contacts the housing, the first magnetic attraction member and the second magnetic attraction member are attracted to each other.

[0024] The beneficial effects of this utility model are as follows: The power bank provided by this utility model has a rotatable closed-loop design of the shell, flexible strip and folding part. When unfolded, it forms a closed-loop gap that allows the palm to pass through, so that the power bank can be fixed on the user's palm or back of the hand. This closed-loop gap directly provides physical binding for the palm, significantly increasing the grip contact area and friction, and reducing the risk of the power bank falling off. When stored, the flexible strip covers the folding part, reducing the overall thickness to a minimum, avoiding the addition of new protruding structures, and taking into account both portability and aesthetics. It overcomes the defects of existing ring buckles, straps and other solutions that are inconvenient to store. Attached Figure Description

[0036] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0037] Please refer to Figures 1 to 9 A type of power bank, including

[0038] Casing 1;

[0039] The flexible strip 2 has a first hinge part 21 at one end and a second hinge part 22 at the other end. The first hinge part 21 is rotatably mounted on the outer wall of the housing 1.

[0040] The folding member 3 has a third hinge 31 at one end and a fourth hinge 32 at the other end. The third hinge 31 is rotatably connected to the second hinge 22, and the fourth hinge 32 is rotatably mounted on the outer side wall of the housing 1.

[0041] When the third hinge 31 separates from the side wall of the housing 1, a closed-loop gap is formed between the housing 1, the flexible strip 2 and the folding member 3, allowing a hand to pass through.

[0042] When the third hinge portion 31 contacts the side wall of the housing 1, the flexible strip 2 covers the folding member 3.

[0043] As can be seen from the above description, the beneficial effects of this utility model are as follows: through the rotatable closed-loop design of the shell 1, flexible strip 2 and folding part 3, a closed-loop gap is formed in the unfolded state, allowing the palm to pass through, so that the power bank can be secured to the user's palm or back of the hand; this closed-loop gap directly provides physical binding for the palm, significantly increasing the grip contact area and friction, and reducing the risk of the power bank falling off the hand; in the storage state, the flexible strip 2 covers the folding part 3, reducing the overall thickness to a minimum, avoiding the addition of protruding structures, taking into account both portability and aesthetics, and overcoming the defects of inconvenient storage of existing ring buckles, straps and other solutions.

[0044] Furthermore, the outer side wall of the housing 1 is provided with a receiving groove 11, which is used to receive the folding piece 3.

[0045] As described above, a receiving groove 11 is provided on the outer wall of the housing 1, and the folding piece 3 can be completely embedded in the groove, eliminating the protruding structure, preventing scratches on clothing or pockets, and improving carrying comfort and appearance integrity.

[0046] Furthermore, the outer side wall of the housing 1 is also provided with a pick-up and put-out slot 12 that communicates with the receiving slot 11.

[0047] As described above, the pick-and-place slot 12, which is connected to the receiving slot 11, forms a "finger-holding position" so that the user can easily pick up the folding part 3 with their fingertips, significantly reducing the difficulty of unfolding the operation and enabling quick switching of the function state with one hand.

[0048] Furthermore, the outer side wall of the housing 1 is also provided with a support frame 4, one end of the support frame 4 is a hinge end 41, and the other end is a support end 42; the hinge end 41 is rotatably mounted on the housing 1, and the support end 42 is used to contact the external component 5.

[0049] As can be seen from the above description, after adding the flip-up support frame 4, the power bank can stand up on its own in a desktop setting, freeing up the hands for video viewing or video calls; the support frame 4 and the anti-drop mechanism share the same shell 1, avoiding extra parts and keeping the whole machine compact.

[0050] Furthermore, the fourth hinge portion 32 is rotatably mounted on the support end 42 of the support frame 4. When the support end 42 contacts the external component 5, one side wall surface of the folding member 3 is in contact with the contact surface of the external component 5.

[0051] As described above, the fourth hinge part 32 of the folding part 3 is directly installed on the support end 42, making the folding part 3 itself part of the support foot; when the support end 42 contacts the table, the side wall of the folding part 3 simultaneously adheres to the table, increasing the contact area, improving support stability and reducing the risk of tipping over.

[0052] Furthermore, the folding member 3 is provided with a damping layer 33, which is used to fit with the contact surface of the external component 5.

[0053] As described above, a damping layer 33 (such as silicone or TPU coating) is provided on the side wall of the folding component 3, which can adapt to uneven desktops, increase the coefficient of friction, prevent the bracket from sliding, and reduce vibration noise.

[0054] Furthermore, the flexible strip 2 is made of silicone.

[0055] As described above, the flexible strip 2 is made of silicone, which has both a soft touch and anti-slip properties, improving hand grip comfort. It can also return to its original shape after repeated bending, extending its service life.

[0056] Furthermore, the flexible strip 2 has a perforated hole 23.

[0057] As can be seen from the above description, opening perforated holes 23 on the flexible strip 2 can reduce weight and material costs on the one hand, and improve breathability and heat dissipation efficiency on the other hand, making it less likely to accumulate sweat when held for a long time.

[0058] Furthermore, the number of the perforated holes 23 is multiple.

[0059] As described above, setting multiple perforated holes 23 to form an array can further optimize weight distribution and heat dissipation channels, while also forming a brand identification pattern on the appearance, thereby enhancing product differentiation.

[0060] Furthermore, the folding member 3 is provided with a first magnetic suction member 34, and the housing 1 is provided with a second magnetic suction member 13. When the third hinge part 31 contacts the housing 1, the first magnetic suction member 34 and the second magnetic suction member 13 are attracted to each other.

[0061] As described above, by utilizing the magnetic attraction of the first magnetic member 34 and the second magnetic member 13, the third hinge part 31 is firmly attached to the housing 1 in the storage state, preventing the flexible strip 2 and the folding part 3 from accidentally popping out; the magnetic positioning is clear, and the user can complete the storage and locking without additional buckles, making the operation simpler and more reliable.

[0062] Please refer to Figures 1 to 7 Embodiment 1 of this utility model is as follows: a power bank for replenishing power to portable electronic devices such as mobile phones, Bluetooth headsets, tablets, and smartwatches. The power bank includes a shell 1, a flexible strip 2, and a folding component 3. A power source is located inside the shell 1, and at least one power output terminal is located outside the shell 1. The power output terminal includes, but is not limited to, a charging cable, a charging coil, a Micro-USB interface, a Lightning interface, and a Type-C interface, etc., which can be specifically configured according to actual application requirements. Specifically, one end of the flexible strip 2 is provided with a first... The first hinge 21 has a second hinge 22 at one end and is rotatably mounted on the outer side wall of the housing 1. The folding member 3 has a third hinge 31 at one end and a fourth hinge 32 at the other end. The third hinge 31 is rotatably connected to the second hinge 22, and the fourth hinge 32 is rotatably mounted on the outer side wall of the housing 1. Specifically, when the third hinge 31 separates from the side wall of the housing 1, a closed-loop gap (e.g., a hand can pass through) is formed between the housing 1, the flexible strip 2, and the folding member 3. Figure 3 and Figure 4 (as shown); when the third hinge 31 contacts the side wall of the housing 1, the flexible strip 2 covers the folding member 3 (as shown). Figure 1 and Figure 2 As shown in the diagram; it can be understood that through the rotatable closed-loop design of the shell 1, flexible strip 2 and folding part 3, a closed-loop gap is formed in the unfolded state, allowing the palm to pass through, so that the power bank can be secured to the user's palm or back of the hand; this closed-loop gap directly provides physical binding for the palm, significantly increasing the grip contact area and friction, reducing the risk of the power bank falling off the hand; in the storage state, the flexible strip 2 covers the folding part 3, reducing the overall thickness to a minimum, avoiding the addition of protruding structures, taking into account both portability and aesthetics, and overcoming the shortcomings of existing ring buckles, straps and other solutions that are inconvenient to store.

[0063] Specifically, in this embodiment, the first hinge portion 21 of the flexible strip 2 is rotatably connected to the housing 1, the second hinge portion 22 is rotatably connected to the third hinge portion 31, and the fourth hinge portion 32 is rotatably connected to the housing 1 via a rigid pivot. Of course, in other embodiments, the first hinge portion 21 of the flexible strip 2 is rotatably connected to the housing 1, the second hinge portion 22 is rotatably connected to the third hinge portion 31, and the fourth hinge portion 32 is rotatably connected to the housing 1 via a damping pivot.

[0064] Preferably, the outer side wall of the housing 1 is provided with a receiving groove 11, which is used to receive the folding piece 3. It can be understood that by providing a receiving groove 11 on the outer side wall of the housing 1, the folding piece 3 can be completely embedded in the groove, eliminating the protruding structure, preventing it from scratching clothing or pockets, and improving carrying comfort and appearance integrity. Specifically, the outer side wall of the housing 1 is also provided with a pick-and-place groove 12 that communicates with the receiving groove 11. The pick-and-place groove 12 that communicates with the receiving groove 11 forms a "finger-holding position", which allows the user to easily pick up the folding piece 3 with their fingertips, significantly reducing the difficulty of unfolding operation and enabling quick switching of functional states with one hand.

[0065] In this embodiment, the flexible strip 2 is made of silicone. Silicone combines a soft touch with anti-slip properties, improving grip comfort, and can still return to its original shape after repeated bending, extending its service life. Specifically, the flexible strip 2 has perforated holes 23. The perforated holes 23 can reduce weight and material costs, and improve breathability and heat dissipation efficiency, preventing sweat buildup during prolonged use. Figure 1 As shown, in this embodiment, the number of the hollow holes 23 is one, and the hollow hole 23 is elongated.

[0066] In addition, in some other embodiments, the shape of the hollow hole 23 can be circular or other polygonal, and the number of hollow holes 23 can also be multiple. For example, multiple hollow holes 23 can be set to form an array, which can further optimize the weight distribution and heat dissipation channels, while forming a brand identification pattern in appearance and enhancing product differentiation.

[0067] Please combine Figures 5 to 7The outer wall of the housing 1 is also provided with a support frame 4, one end of which is a hinge end 41 and the other end is a support end 42. The hinge end 41 is rotatably mounted on the housing 1, and the support end 42 is used to contact an external component 5. The external component 5 can be an object with a surface for placing items, such as the ground, a table, or a vehicle dashboard. It is understood that with the addition of the rotatable support frame 4, the power bank can stand upright as a stand in a table setting, freeing up the hands for video viewing or video calls. The support frame 4 and the anti-fall mechanism share the housing 1. To avoid additional parts and maintain the compactness of the whole machine, the fourth hinge part 32 is rotatably mounted on the support end 42 of the support frame 4. When the support end 42 contacts the external component 5, one side wall of the folding part 3 is in contact with the contact surface of the external component 5, and the fourth hinge part 32 of the folding part 3 is directly mounted on the support end 42, so that the folding part 3 itself becomes part of the support foot. When the support end 42 contacts the tabletop, the side wall of the folding part 3 is in contact with the tabletop, increasing the contact area, improving support stability and reducing the risk of tipping over.

[0068] Please refer to Figure 8 The second embodiment of this utility model is a further improvement on the folding member 3 based on the first embodiment. In this second embodiment, the folding member 3 is provided with a damping layer 33. The damping layer 33 is used to fit with the contact surface of the external component 5. The damping layer 33 is provided on the side wall of the folding member 3. The material of the damping layer 33 is silicone, TPU coating, etc., which can adapt to the unevenness of the contact surface of the external component 5, improve the friction coefficient, prevent the bracket from sliding, and reduce vibration noise.

[0069] Please refer to Figure 9 The third embodiment of this utility model is a further improvement on the folding member 3 based on the first embodiment. In this third embodiment: the folding member 3 is provided with a first magnetic suction member 34, and the housing 1 is provided with a second magnetic suction member 13. When the third hinge part 31 contacts the housing 1, the first magnetic suction member 34 and the second magnetic suction member 13 are attracted to each other. The first magnetic suction member 34 and the second magnetic suction member 13 are magnets. By utilizing the magnetic attraction of the first magnetic suction member 34 and the second magnetic suction member 13, the third hinge part 31 is firmly attracted to the housing 1 in the storage state, preventing the flexible strip 2 and the folding member 3 from accidentally popping out. The magnetic positioning is clear, and the user can complete the storage and locking without additional buckles, making the operation simpler and more reliable.

[0070] Alternatively, a magnetic attraction element that can attract each other can be provided between the support frame 4 and the housing 1, or a magnetic attraction element that can attract each other can be provided between the flexible strip 2 and the support frame 4. The specific configuration can be made according to the actual application requirements.

[0071] In summary, the power bank provided by this utility model features a rotatable closed-loop design consisting of the shell, flexible strip, and folding component. When unfolded, it forms a closed-loop gap through which the palm can pass, allowing the power bank to be securely fitted onto the user's palm or back of hand. This closed-loop gap directly provides physical binding to the palm, significantly increasing the grip contact area and friction, and reducing the risk of the power bank falling off. When folded, the flexible strip covers the folding component, minimizing the overall thickness and avoiding any new protruding structures. This design balances portability and aesthetics, overcoming the inconvenience of storage found in existing ring buckles, straps, and other similar solutions.
