Description

Technical Field

[0001] This invention relates to the field of electronic device technology, and more particularly to a power bank. Background Technology

[0002] Power banks, also known as portable power banks, are widely used in various scenarios due to their small size and portability. Because of these diverse applications, the waterproof performance of power banks has become a major concern. Therefore, improving the waterproof performance of power banks has become a key technical challenge. Summary of the Invention

[0003] The present invention provides a power bank to solve at least one of the problems mentioned in the background art.

[0004] The power bank according to this application includes a housing, a knob, an insert, and a light. The knob includes a rotating wheel and a rotating shaft connected to the rotating wheel. The rotating shaft is rotatably inserted into the housing, and a first sealing member is sleeved on the rotating shaft to seal the gap between the housing and the rotating shaft. The insert is at least partially embedded in the housing, and a second sealing member is provided between the insert and the housing to seal the gap between the housing and the insert. The light and the housing are integrally formed.

[0005] The power bank of this embodiment utilizes a first sealing element to achieve dynamic sealing at the rotational connection between the knob and the housing, preventing moisture and dust from intruding through the gap in the shaft and improving the waterproof and dustproof rating. The second sealing element provides static sealing at the embedding point between the insert and the housing. The integrated structure of the light and housing eliminates assembly gaps, avoiding the risk of seal failure caused by assembly seams, while also simplifying the manufacturing process and improving structural compactness and overall appearance. These multi-dimensional waterproof sealing structures work synergistically to ensure the power bank meets the IPX6 waterproof standard, effectively resisting the risk of water ingress from strong water jets, rain, and accidental water drop, significantly improving the power bank's environmental adaptability and lifespan.

[0006] In some embodiments, the power bank includes a switch disposed within the housing, one end of the rotating shaft being inserted into the switch, the knob being capable of reciprocating relative to the housing along the axial direction of the rotating shaft, and the rotating shaft being capable of triggering the switch when it moves or rotates.

[0007] In this way, the rotation adjustment and press trigger functions are integrated into the same knob, reducing the number of independent buttons, simplifying the appearance layout, and enabling different functions of the power bank to be controlled through rotation, pressing and other operations. While ensuring waterproof sealing, it improves the user's ease of operation of the power bank's functions (such as switch control).

[0008] In some embodiments, the rotating shaft is provided with an elastic element and a gasket. The gasket is sleeved on the rotating shaft and abuts against the first sealing element. The two ends of the elastic element abut against the gasket and the rotating wheel, respectively. After the knob is pressed, the elastic element drives the knob to reset. In this way, the elastic element automatically resets the knob after it is pressed, improving the ease of operation and user experience, and ensuring that the knob returns to its initial position after the switch is triggered, facilitating repeated operation.

[0009] In some embodiments, a first retaining ring is engaged with the rotating shaft, the first retaining ring abutting against the surface of the housing to prevent the knob from separating from the housing. Thus, the first retaining ring stabilizes the position of the knob, facilitating its use.

[0010] In some embodiments, the power bank includes a display screen disposed on one side of the knob, the display screen being able to display in different modes according to different operations of the knob.

[0011] In this way, the display screen switches display modes according to the knob operation, realizing diversified and intelligent display of information (such as power level and working status), improving users' intuitive understanding of the power bank's status, and realizing intelligent linkage between display content and operation mode.

[0012] In some embodiments, the insert includes at least one of a button, a carrying cord, and a data cable. The insert includes an insert portion embedded in the housing. The second seal is disposed on the insert portion. The peripheral wall of the second seal has a plurality of annular protrusions, which are arranged at intervals.

[0013] In this way, the annular protrusions undergo elastic deformation under pressure to compensate for manufacturing tolerances. Multiple annular protrusions form a multi-level sealing lip, providing redundant protection even if a single seal fails, significantly improving waterproof reliability. The variety of embedded components (buttons, carrying straps, data cables) increases the functionality and adaptability of the power bank to different usage scenarios.

[0014] In some embodiments, the embedded component is a data cable, one end of which is provided with the embedded portion. The power bank also includes a connector disposed on the data cable, which enables the data cable to be in a retracted state or an extended state. The length of the data cable in the extended state is greater than its length in the retracted state.

[0015] In this way, the connector allows for switching between storing and unfolding the data cable. When stored, it reduces the size, avoids tangling and wear, and reduces the risk of losing parts; when unfolded, it provides sufficient length to meet usage needs, improving the portability and practicality of the data cable.

[0016] In some embodiments, the data cable includes a cable body and a connector. The first end of the cable body is provided with the embedded portion, and the second end of the cable body is provided with the connector. In the stored state, the data cable is folded into a segmented state from the connector. The portion of the connector and the portion of the cable body near the embedded portion are both provided on the connector. In the unfolded state, the connector separates from the connector to unfold the cable body.

[0017] This segmented folding design keeps the data cable neatly organized during storage, effectively avoiding the tangling and knotting problems common with traditional data cables. The connector and the portion of the cable body near the mounting point are fixed to the connector base, forming a stable carrying handle for easy carrying. To unfold, simply detach the connector from the connector base, and the cable body will unfold naturally without any additional tidying. This design not only improves storage efficiency but also protects the data cable structure, reducing damage to internal wires caused by frequent tangling and bending, thus extending the cable's lifespan.

[0018] In some embodiments, the data cable's embedded portion is provided with a second retaining ring, which is spaced apart from the second sealing member. The second retaining ring engages with the housing to prevent the embedded portion from detaching from the housing. Thus, the second retaining ring makes the connection between the data cable and the housing more stable, which is beneficial for the use of the data cable.

[0019] In some embodiments, the housing includes a frame and a cover plate disposed on the frame, the cover plate being located on one side of the frame in a first direction, and the lighting lamp being integrally formed with the cover plate.

[0020] In this way, the lighting fixture and the cover are molded as one piece, simplifying the structure, improving the integrity and sealing of the housing, further enhancing waterproof performance, and ensuring stable lighting function.

[0021] In some embodiments, the housing includes a grip disposed on the frame, the grip being located on one side of the frame in a second direction, the grip having a less rigidity than the frame having a first direction intersecting the second direction.

[0022] Thus, the lower hardness of the grip components helps improve grip comfort. The grip and lighting functions are arranged in two intersecting directions, making the shell partition reasonable and optimizing the user experience.

[0023] In some embodiments, the frame is provided with a through hole, the through hole being connected to the internal space of the frame and the external environment, and the power bank includes a waterproof and breathable membrane covering the through hole.

[0024] In this way, the waterproof and breathable membrane allows gas inside the shell to escape to balance the air pressure, while preventing external liquid from entering, effectively balancing the pressure difference between the inside and outside, and improving waterproof performance and safety in use.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0030] Please see Figures 1-3 The power bank 100 of this application includes a housing 10, a knob 20, an insert 30, and a light 40. The knob 20 includes a rotating wheel 21 and a rotating shaft 22 connected to the rotating wheel 21. The rotating shaft 22 is rotatably inserted into the housing 10. A first sealing member 23 is sleeved on the rotating shaft 22, and the first sealing member 23 seals the gap between the housing 10 and the rotating shaft 22. The insert 30 is at least partially embedded in the housing 10. A second sealing member 31 is provided between the insert 30 and the housing 10, and the second sealing member 31 seals the gap between the housing 10 and the insert 30. The light 40 and the housing 10 are integrally formed.

[0031] The power bank 100 of this application embodiment uses a first sealing member 23 to achieve dynamic sealing at the rotational connection between the knob 20 and the housing 10, preventing moisture and dust from entering through the gap of the rotating shaft 22 and improving the waterproof and dustproof level. The second sealing member 31 can achieve static sealing at the embedding point between the insert 30 and the housing 10. The lighting lamp 40 and the housing 10 are integrally formed, which can eliminate the assembly gap between the lighting lamp 40 and the housing 10, avoid the risk of sealing failure caused by assembly gaps, and at the same time simplify the production process and improve the structural compactness and overall appearance.

[0032] The combined effect of these multi-dimensional sealing and waterproof structures ensures that the Power Bank 100 meets the IPX6 waterproof standard, effectively resisting the risk of water ingress in scenarios such as strong water spray, rain, and accidental water drop, significantly improving the Power Bank 100's environmental adaptability and service life.

[0033] Specifically, the housing 10 is a major component of the power bank 100. The housing 10 can be made of a single material or a composite of multiple materials. For example, different parts of the housing 10 can be made of aluminum alloy and engineering plastics, respectively.

[0034] The surface of the rotary wheel 21 of the knob 20 has an anti-slip texture to enhance the tactile feedback during user operation. The rotating shaft 22 can be made of a high-strength metal material, such as stainless steel or aluminum alloy, which gives it corrosion resistance and mechanical strength. An annular limiting groove can be provided on the rotating shaft 22 to achieve axial positioning in conjunction with the first seal 23. The first seal 23 can be a rubber O-ring, which has excellent oil resistance, high temperature resistance, and resilience, ensuring long-term reliable sealing.

[0035] The embedded part 30 can be an exposed functional component such as a button 32, a lifting rope 33, or a data cable 34 interface. The second sealing element 31 is used to achieve a seamless fit between the embedded part 30 and the housing 10. The second sealing element 31 can be made of silicone. With the high elasticity and self-adaptive deformation capability of silicone, it can effectively fill the assembly tolerance between the embedded part 30 and the housing 10, ensuring the long-term stability of the static seal.

[0036] The lighting lamp 40 can be integrally molded with the housing 10 using a secondary injection molding process. The lighting lamp 40 can be connected to the circuit board inside the housing 10 via wires.

[0037] Please see Figures 3-4 In some embodiments, the power bank 100 includes a switch 24 disposed within the housing 10, one end of a rotating shaft 22 is inserted into the switch 24, and a knob 20 is capable of reciprocating relative to the housing 10 along the axial direction of the rotating shaft 22. The rotating shaft 22 can trigger the switch 24 when it moves or rotates.

[0038] In this way, integrating the rotation adjustment and press trigger functions into the same knob 20 can reduce the number of independent operating components, simplify the appearance layout of the power bank 100, and enable different function control of the power bank 100 through rotation, pressing and other operations, thereby improving the user's ease of operation of the power bank 100 functions while ensuring waterproof sealing.

[0039] Specifically, switch 24 can be installed on a circuit board inside housing 10, forming a precision mechanical coupling with the end of rotating shaft 22; when the user presses knob 20, the axial displacement of rotating shaft 22 pushes the contacts of switch 24 to close, realizing instantaneous on / off control; rotating knob 20 causes rotating shaft 22 to rotate circumferentially, which can drive the internal encoder to identify angle changes and output different control signals.

[0040] Please see Figure 3-4 In some embodiments, the rotating shaft 22 is provided with an elastic element 25 and a gasket 26. The gasket 26 is sleeved on the rotating shaft 22 and abuts against the first seal 23. The two ends of the elastic element 25 abut against the gasket 26 and the rotating wheel 21 respectively. After the knob 20 is pressed, the elastic element 25 drives the knob 20 to reset.

[0041] In this way, the gasket 26 can prevent the elastic element 25 from directly contacting the first seal 23, thereby improving the lifespan and waterproof performance of the first seal 23. The elastic element 25 allows the knob 20 to automatically reset after being pressed, improving the ease of operation and user experience, and ensuring that the knob 20 returns to its initial position after the switch 24 is triggered, facilitating repeated operation.

[0042] Specifically, the elastic element 25 can be a helical spring or a disc spring, and its pre-compression amount can be specifically designed to ensure sufficient reset force while avoiding excessive pressing resistance; the two ends of the elastic element 25 abut against the inner wall of the knob 20 and the surface of the housing 10 respectively, forming a stable force.

[0043] Please see Figures 3-4 In some embodiments, a first retaining ring 27 is engaged with the rotating shaft 22. The first retaining ring 27 abuts against the surface of the housing 10 to prevent the knob 20 from separating from the housing 10. In this way, the first retaining ring 27 can stabilize the position of the knob 20, which is beneficial to the use of the knob 20.

[0044] Please see Figure 3 In some embodiments, the power bank 100 includes a display screen 50 disposed on one side of the knob 20, and the display screen 50 can display in different modes according to different operations of the knob 20.

[0045] In this way, the display screen 50 switches display modes according to the operation of the knob 20, realizing diversified and intelligent display of information (such as power level and working status), enhancing the user's intuitive understanding of the status of the power bank 100, and realizing intelligent linkage between display content and operation mode.

[0046] Specifically, the display screen 50 can be placed inside the housing 10, and its display area is presented to the outside through a transparent window reserved on the housing 10, with the edge of the window being sealed integrally with the housing 10.

[0047] The knob 20 can be operated by rotating, pressing, and holding. The display screen 50 can display in landscape mode and portrait mode.

[0048] In one example, when the user double-clicks knob 20, the display 50 can switch between landscape and portrait modes. For instance, when the display 50 is in landscape mode, it can show key parameters such as current battery level, input / output power, and temperature. When the user presses and holds knob 20, they can enter the current mode adjustment interface. Furthermore, each 15° rotation of knob 20 switches the current level, and the display 50 dynamically displays the voltage and current change curves in real time. When the user clicks knob 20, they can control the power bank 100 to turn it on or off, either turning the screen off or on.

[0049] Please see Figures 6-9 In some embodiments, the insert 30 includes at least one of a button 32, a lifting cord 33, and a data cable 34. The insert 30 includes an insert portion 35 embedded in the housing 10. A second seal 31 is disposed on the insert portion 35. The peripheral wall of the second seal 31 is provided with a plurality of annular protrusions 311, which are arranged at intervals.

[0050] In this way, the annular protrusion 311 undergoes elastic deformation under pressure to compensate for manufacturing tolerances. Multiple annular protrusions 311 form a multi-level sealing lip, which provides redundant protection even if a single seal fails, significantly improving waterproof reliability. The variety of embedded parts 30 (button 32, carrying strap 33, data cable 34) increases the functionality and adaptability of the power bank 100 to various usage scenarios.

[0051] Specifically, the second seal 31 can be made of TPU or liquid silicone material, and the second seal 31 can be integrally injection molded with the embedding part 35. Multiple annular protrusions 311 are provided on the embedding part 35. The cross-section of the annular protrusions 311 is trapezoidal or arc-shaped. After compression and deformation of the multiple annular protrusions 311, the edges of each annular protrusion 311 are tightly attached to the shell 10, forming a labyrinthine sealing path, which effectively prevents moisture from seeping in along the axial direction of the embedding part 35.

[0052] Please see Figure 2 , Figures 9-11 In some embodiments, the embedded member 30 is a data cable 34, one end of which is provided with an embedded part 35. The power bank 100 also includes a connector 60 disposed on the data cable 34. The connector 60 enables the data cable 34 to be in a retracted state or an extended state. The length of the data cable 34 in the extended state is greater than the length in the retracted state.

[0053] In this way, the connector 60 enables the data cable 34 to be switched between being stored and unfolded. When stored, it reduces the size, avoids tangling and wear, and reduces the risk of losing parts; when unfolded, it provides sufficient length to meet usage needs, improving the portability and practicality of the data cable 34.

[0054] Specifically, the data cable 34 can be used for charging, data transfer, or powering the earphone case. The data cable 34 can use an insulated wire body such as TPE and has built-in conductive wires, giving it bend resistance. The connector 60 and the data cable 34 can be fixedly connected or slidably connected. For example, the connector 60 can be integrally injection molded from ABS material and fixed to half the length of the data cable 34 via a hot-pressing process.

[0055] Please see Figures 9-11 In some embodiments, the data cable 34 includes a cable body 341 and a connector 342. The first end of the cable body 341 is provided with an embedding part 35, and the second end of the cable body 341 is provided with a connector 342. In the stored state, the data cable 34 forms a segmented folded state from the connector 60. The connector 342 and the portion of the cable body 341 near the embedding part 35 are both provided on the connector 60. In the unfolded state, the connector 342 separates from the connector 60 to unfold the cable body 341.

[0056] Thus, the segmented folding storage design keeps the data cable 34 in a neat shape when stored, effectively avoiding the problems of tangling and knotting common with traditional data cables 34. The connector 342 and the portion of the cable body 341 near the embedding part 35 are both fixed to the connector 60, forming a stable carrying handle structure for easy carrying. When unfolding, simply detach the connector 342 from the connector 60, and the cable body 341 will unfold naturally without additional tidying. This design not only improves storage efficiency but also protects the structure of the data cable 34, reducing damage to the internal wires caused by frequent tangling and bending, and extending the lifespan of the data cable 34. Furthermore, the fixing and detachment of the connector 342 from the connector 60 allows for quick switching between the stored and unfolded states of the data cable 34.

[0057] Specifically, the cable body 341 can be made of TPE elastic insulation material. In one example, the connector 342 can be a USB connector, Type-C connector, Lightning connector, etc. The connector 342 can be made of aluminum alloy shell and anodized to improve the wear resistance and corrosion resistance of the connector 342. The connector 342 and the cable body 341 can be fixed by injection molding, and a stress buffer sleeve is set at the connection to prevent the cable body 341 from breaking due to frequent bending.

[0058] In one embodiment, the connector 60 can be fixed at the midpoint of the line body 341 by injection molding, so that the line body 341 can be folded in half at the connector 60, making it easier to store.

[0059] In its folded state, the data cable 34 folds in segments from the connector 60. The data cable 34 can be folded once or multiple times at the connector 60, depending on the cable length and the structural design of the connector 60. After folding, the data cable 34, together with the connector 60, forms a closed loop structure, which can be directly slipped around the neck or wrist when worn. The circumference of the loop structure dynamically changes with the number of folds.

[0060] When unfolded, the data cable 34 extends to meet daily usage distance requirements. When folded, the data cable 34 can be double-folded to form a 20-30cm carrying loop, a size that fits comfortably in the hand for easy carrying or storage with devices, preventing the excessively long data cable 34 from hanging haphazardly.

[0061] When one end of the data cable 34 is pulled out from the connector 60, the data cable 34 can naturally unfold to a standard usage length of 80cm-120cm, which can meet the needs of different distances such as handheld device charging and desktop charging, without the need to carry additional data cables 34 of different lengths. This state switching does not require a complex stretching structure, but is achieved through a simple folding and pulling operation. The structure is stable and has a long service life, adapting to diverse usage scenarios.

[0062] Please see Figure 10 and Figure 11 In some embodiments, the connector 60 includes a base 61 and a retaining ring 62 disposed on the side wall of the base 61. The wire body 341 is slidably inserted into the retaining ring 62, and the connector 342 can be fixed to the base 61 or separated from the base 61.

[0063] Thus, the clasp 62 and the cable body 341 slide together to achieve flexible length adjustment. The clasp 62 constrains the sliding trajectory of the cable body 341 to ensure a smooth and orderly folding / unfolding process and prevent cable misalignment. The detachable design of the connector 342 makes the switching between storage and unfolding efficient, improving space utilization and ease of operation.

[0064] Specifically, the base 61 is the core load-bearing structure of the data cable 34 assembly. The base 61 and the retaining ring 62 can be integrally injection molded to ensure structural strength while reducing weight. For example, it can be made of PC+ABS composite material through injection molding, balancing strength and lightweight. Since the lateral dimension of the connector 342 is larger than the dimension of the cable body 341, connecting the connector 342 to the base 61 makes it easier to fix the free end of the data cable 34 onto the base 61, preventing slippage.

[0065] Please see Figure 10 and Figure 11 In some embodiments, the base 61 is provided with a storage space 611 and a through hole 6102. The storage space 611 is used to store the connector 342, and the wire body 341 is inserted into the through hole 6102. The storage space 611 and the through hole 6102 are independently arranged on both sides of the base 61.

[0066] Thus, the storage space 611 and the through hole 6102 are independently arranged on both sides of the base 61, allowing the connector 342 and the wire body 341 to be stored in an orderly manner, with a clear structure, avoiding clutter. In addition, the storage space 611 can provide sealed protection for the connector 342, preventing dust and collisions.

[0067] Specifically, the storage space 611 features a semi-open U-shaped groove design, with elastic ribs on the inner wall to prevent wear during plugging and unplugging of the connector 342, while also ensuring stable storage of the connector 342 through an interference fit. The cable body 341 passes through the through hole 6102, allowing the connector 60 to remain connected to the data cable 34, facilitating the folding and unfolding of the data cable 34.

[0068] Please see Figure 10 and Figure 11 In some embodiments, the storage space 611 extends through both ends of the base 61 along its own length to form two openings 612. The base 61 is also provided with a slit 613 communicating with the storage space 611. The two ends of the slit 613 in the length direction are respectively connected to the two openings 612. The connector 342 is configured such that after the online body 341 passes through the two openings 612, it is inserted into the storage space 611 through one of the openings 612.

[0069] Thus, the through-hole 612 and slit 613 structure allows the connector 342 to be inserted into or removed from the storage space 611 from one side of the storage space 611, which helps to improve the stability of the connection between the connector 342 and the base 61.

[0070] Specifically, the storage space 611 extends through both ends of the base 61 to form an opening 612. The edges of the opening 612 can be rounded to avoid cable wear. The width of the slit 613 is less than the thickness of the connector 342 and greater than the thickness or diameter of the cable body 341, so that the cable body 341 can be inserted into the storage space 611 through the slit 613.

[0071] In one example, when the data cable 34 is being stored, the cable body 341 can be folded in half while unfolded. Then, the folded cable body 341 is inserted into the storage space 611 through the slit 613. Next, the connector 342 is aligned with the opening 612 on one side of the base 61 and pushed into the storage space 611 along its length. At this point, the cable body 341 forms a double-folded structure, and the slit 613 provides anti-detachment fixation, completing the storage state switch.

[0072] Please see Figure 10 and Figure 11 In some embodiments, the connector 342 is provided with a stop portion 3421 on the side near the wire body 341. The stop portion 3421 abuts against the base 61 in the storage space 611 to restrict the connector 342 from leaving the storage space 611 in the direction of the wire body 341.

[0073] Thus, the stop part 3421 abuts against the base 61 to form an anti-detachment structure, preventing the connector 342 from accidentally falling off due to vibration or pulling when stored, thereby improving the reliability of the data cable 34.

[0074] Specifically, the stop 3421 can be an annular stepped structure on the side of the connector 342 near the cable body 341. The storage space 611 can be provided with symmetrically distributed limiting protrusions 614 at the opening 612. When the connector 342 is inserted along the length of the storage space 611, the front end of the stop 3421 contacts the limiting protrusion 614 and forms an axial limit, thus preventing the connector 342 from dislodging from the opening 612 of the storage space 611. This allows the folded data cable 34 to have a certain load-bearing capacity, making it convenient to carry the external device through the data cable 34 when the connector 60 is connected to the external device.

[0075] Please see Figure 10 and Figure 11 In some embodiments, the power bank 100 also includes a cap 71 and a connecting wire 72 connecting the cap 71 and the connector 342, wherein the cap 71 is detachably fitted onto the outside of the connector 342.

[0076] In this way, the cap 71 is connected to the connector 342 via the connecting wire 72, which avoids the problem of the cap 71 being easily lost; at the same time, it is dustproof and waterproof, protecting the metal contacts inside the connector 342 from corrosion and extending its service life.

[0077] Specifically, the cap 71 can be injection molded from silicone material, and the connecting wire 72 can also be made of silicone material. The inner side of the cap 71 has two annular sealing grooves that interlock with the sealing ribs on the outer side of the connector 342 to achieve IPX6 waterproof rating. The outer side of the cap 71 can be provided with anti-slip bumps for user convenience.

[0078] With the data cable 34 extended, the cap 71 can be held and pulled out axially, and the connecting cable 72 will naturally stretch to the working length. At this time, the cap 71 hangs over the side of the connector 342 through the connecting cable 72, without affecting the use of the connector 342. When the connector 342 is not in use, the cap 71 is aligned with the connector 342 interface and pushed in axially.

[0079] It should be noted that when storing the data cable 34, the cap 71 can be embedded together with the connector 342 in the storage space 611.

[0080] like Figure 2 As shown, in some embodiments, the housing 10 includes a frame 11 and a cover plate 12 disposed on the frame 11. The cover plate 12 is located on one side of the frame 11 in a first direction, and the lighting lamp 40 and the cover plate 12 are integrally formed.

[0081] In this way, the lighting lamp 40 and the cover plate 12 are integrally formed, simplifying the structure, improving the integrity and sealing of the housing 10, further enhancing the waterproof performance, and ensuring the stability of the lighting function.

[0082] Specifically, the frame 11 is the main part of the shell 10, and the frame 11 can be three-dimensional. The frame 11 can be molded by injection molding. The cover plate 12 can be made of alloy material to enhance structural strength. The cover plate 12 is first made with precision carving to achieve the precise shape and detailed texture of the decorative cover, and then the surface is treated with anodizing sandblasting to give the surface of the cover plate 12 a delicate and uniform metallic texture, enhancing the overall high-end appearance of the product.

[0083] In one example, two cover plates 12 can be provided, located on the upper and lower sides of the frame 11 respectively, and the lighting lamp 40 can be installed on one of the cover plates 12. The cover plate 12 and the frame 11 can be connected by a snap-fit ​​method, and then waterproof adhesive is applied to the connection between the cover plate 12 and the frame 11 to further enhance the sealing effect.

[0084] The lighting lamp 40 and the cover plate 12 can be integrally molded through a secondary injection molding process. The lighting lamp 40 is, for example, an LED lamp.

[0085] In some embodiments, the data cable 34 is provided with a second retaining ring 36 on the embedded part 35. The second retaining ring 36 is spaced apart from the second sealing member 31. The second retaining ring 36 is engaged with the housing 10 to prevent the embedded part 35 from detaching from the housing 10.

[0086] Thus, the second retaining ring 36 makes the connection between the data cable 34 and the housing 10 more stable, which is beneficial to the use of the data cable 34.

[0087] In one example, when installing the data cable 34, the second retaining ring 36 of the data cable 34 can be inserted into the housing 10 first, and then the second retaining ring 36 can be used to snap onto the insert 35, thereby preventing the data cable 34 from detaching from the housing 10.

[0088] Please see Figure 12 In some embodiments, the housing 10 includes a grip 13 disposed on the frame 11, the grip 13 being located on one side of the frame 11 in a second direction, the grip 13 having a lower hardness than the frame 11, and the first direction intersecting the second direction.

[0089] Thus, the lower hardness of the grip 13 helps to improve grip comfort. The grip and lighting functions are arranged in two intersecting directions, making the shell 10 reasonably divided and optimizing the user experience.

[0090] Specifically, the grip 13 can be made of soft silicone or similar materials, and its surface can be textured to enhance slip resistance. The grip 13 and the frame 11 are tightly fitted together through a nested structure. The second direction is, for example, the width direction of the power bank 100, and the first direction is the height direction of the power bank 100.

[0091] Please see Figure 13 In some embodiments, the frame 11 is provided with a through hole 111, the through hole 111 together with the internal space of the frame 11 and the external environment, and the power bank 100 includes a waterproof and breathable membrane 80 covering the through hole 111.

[0092] In this way, the waterproof and breathable membrane 80 allows the gas inside the shell 10 to escape to balance the air pressure, while preventing external liquid from entering, effectively balancing the pressure difference between the inside and outside, and improving waterproof performance and safety of use.

[0093] Specifically, the waterproof and breathable membrane 80 can be made of ePTFE (expanded polytetrafluoroethylene) material, whose microporous structure diameter is between 0.1 and 5 micrometers. It can block liquid water and dust, and also ensure the smooth exchange of gas inside the casing 10 during battery charging and discharging.

[0094] The waterproof and breathable membrane 80 and the frame 11 can be firmly bonded together by hot pressing or ultrasonic welding to ensure that they do not delaminate or shift during long-term use.

[0095] Please see Figures 2-4 In some embodiments, the housing 10 further includes a mating member 14 disposed on the frame 11, on which the knob 20 and button 32 are both mounted. Specifically, the pivot 22 of the knob 20 passes through the mating member 14, the first retaining ring 27 abuts against the inner surface of the mating member 14, and the rotating wheel 21 is located on the outer side of the mating member 14. The first sealing member 23, the gasket 26, and the elastic member are all located on the outer side of the mating member 14, with the first sealing member 23 abutting against the outward-facing surface of the mating member 14. The mating member 14 can be fixed to the frame 11 by adhesive, achieving not only a stable connection but also a seal between the mating member 14 and the frame 11.

[0096] In some embodiments, the button 32 and the mating part 14 can be integrally formed. For example, the button 32 and the mating part 14 can be injection molded into one piece by a two-stage injection molding process.

[0097] In summary, in one embodiment, the power bank 100 of this application has at least the following beneficial effects: 1.
