Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a mobile power supply. Background Technology

[0002] Currently, portable power banks with built-in charging cables typically have a detachable connector on the main body for easy carrying, with the charging cable coiled into a handle for users to lift. However, as the storage capacity of power banks continues to increase, the required battery size and the power bank's own weight also increase accordingly. This makes it easy for the charging cable connector to accidentally detach from the main body, leading to damage from drops. To provide users with a better user experience, these problems urgently need to be solved. Utility Model Content

[0012] Optionally, in some embodiments, the electrical connector is inserted into the receiving groove along a first direction, the width of the stop portion in the first direction is greater than the width of the snap-fit ​​portion in the first direction; the width of the stop portion in the second direction is less than the width of the snap-fit ​​portion in the second direction, and the second direction is perpendicular to the first direction.

[0013] Optionally, in some embodiments, there are two data cables, two electrical connectors, two receiving slots, and two snap-fit ​​pieces; the two receiving slots are arranged side by side between the two snap-fit ​​pieces, the two electrical connectors are respectively connected to the two data cables, and the two electrical connectors are detachably inserted into the two receiving slots.

[0014] Optionally, in some embodiments, the housing includes a main housing and a sub-housing. The main housing has an installation port communicating with the receiving cavity. The sub-housing is detachably connected to the main housing and covers the installation port. A receiving groove is provided on the sub-housing, and a snap-fit ​​member is provided on the side wall of the sub-housing away from the receiving groove.

[0015] Optionally, in some embodiments, the main housing includes a first half-shell and a second half-shell that interlock with each other; the power assembly includes a mounting bracket, which is detachably connected to one of the first half-shell and the second half-shell, the mounting bracket having a mounting portion, the sub-housing having a positioning portion on the side wall away from the receiving groove, and the fixing portion of the snap-fit ​​member being disposed between the mounting portion and the positioning portion.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0035] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or state relationship based on the orientation or state relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0036] Furthermore, in addition to indicating location or state relationships, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0037] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] Furthermore, unless otherwise explicitly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.

[0040] Please see Figure 1 , Figure 2 and Figure 3 This application provides a portable power bank 100 for charging electronic devices. The portable power bank 100 includes a housing 10 and a power assembly 11 (see...). Figure 6 ), data cable 12, electrical connector 13, and snap-fit ​​connector 14.

[0041] The housing 10 is the main structure of the power bank 100. As a specific example, in this embodiment, the housing 10 is generally rectangular. In other embodiments, the housing 10 can also be generally cubic, cylindrical, or any other shape, and there is no limitation thereto. The housing 10 has an internal receiving cavity 101 (see...). Figure 6 The receiving cavity 101 is a cavity located inside the housing 10, which is used to accommodate other structures of the power bank 100 disposed inside the housing 10. The surface of the housing 10 is provided with a receiving groove 102, which is used for the power connector 13 to be plugged in so that the data cable 12 is bent to form a handle so that the user can lift the power bank 100.

[0042] The power supply assembly 11 is disposed within the receiving cavity 101 and is used to electrically connect to the data cable 12 to provide power to external electronic devices.

[0043] One end of the data cable 12 is electrically connected to the power assembly 11, and the other end extends to the outside of the housing 10. Specifically, one end of the data cable 12 passes through the housing 10 and extends into the receiving cavity 101, while the other end is located outside the housing 10.

[0044] The electrical connector 13 is the specific component that electrically connects the power bank 100 to the electronic device. The electrical connector 13 can be of any type, such as Micro-USB, Type-C, or Lightning connector. The electrical connector 13 is electrically connected to the data cable 12 and is located at the end of the data cable 12 outside the housing 10. The electrical connector 13 is detachably inserted into the receiving slot 102. It should be noted that "the electrical connector 13 is detachably inserted into the receiving slot 102" means that the electrical connector 13 can be fixedly inserted into the receiving slot 102 or removed from it. The electrical connector 13 is provided with a snap-fit ​​groove 131 (see...). Figure 4 The snap-fit ​​groove 131 is used to snap into the snap-fit ​​member 14 so that the electrical connector 13 can be stably inserted into the receiving groove 102.

[0045] A snap-fit ​​connector 14 is disposed in the housing 10, and at least a portion of the structure of the snap-fit ​​connector 14 is accommodated within the receiving groove 102 and extends into the snap-fit ​​groove 131. It should be noted that "at least a portion of the structure of the snap-fit ​​connector 14 extending into the snap-fit ​​groove 131" can include the following situations: the snap-fit ​​connector 14 is in contact with the inner bottom wall of the snap-fit ​​groove 131, or the snap-fit ​​connector 14 is separated from the inner bottom wall of the snap-fit ​​groove 131. Under the action of external force, the snap-fit ​​connector 14 can deform and completely disengage itself from the snap-fit ​​groove 131, thereby losing the effect of locking the electrical connector 13 within the receiving groove 102.

[0046] With the above configuration, since the power bank 100 is equipped with a snap-fit ​​connector 14 and the electrical connector 13 is equipped with a snap-fit ​​slot 131, when the electrical connector 13 is inserted into the receiving slot 102, at least a portion of the structure of the snap-fit ​​connector 14 can be inserted into the snap-fit ​​slot 131 to achieve a snap-fit ​​engagement between the snap-fit ​​connector 14 and the snap-fit ​​slot 131. This improves the stability of the electrical connector 13 within the receiving slot 102 and minimizes the possibility of the electrical connector 13 accidentally dislodging from the receiving slot 102 when the user pulls the data cable 12, thereby reducing the likelihood of the power bank 100 being accidentally dropped. When the user needs to use the power bank 100 to charge an electronic device, the user only needs to pull the data cable 12 forcefully to dislodge the snap-fit ​​connector 14 from the snap-fit ​​slot 131, allowing the electrical connector 13 to be removed from the receiving slot 102 and connected to the electronic device for charging. In summary, the aforementioned power bank 100 allows the electrical connector 13 to be inserted into the receiving slot 102, enabling the data cable 12 to form a handle for the user to lift. Furthermore, due to the presence of the snap-fit ​​connector 14 and the snap-fit ​​slot 131, the snap-fit ​​connector 14 ensures the electrical connector 13 is stably inserted into the receiving slot 102, minimizing the risk of the connector 13 accidentally dislodging from the receiving slot 102 when the user lifts the data cable 12. This improves the safety and reliability of the power bank 100 when the user lifts it via the data cable 12, thereby making it more convenient for the user to carry the power bank 100 and enhancing the user experience.

[0047] Please see Figures 3 to 8 In some embodiments, the snap-fit ​​member 14 includes a snap-fit ​​portion 141, a connecting portion 142, and a fixing portion 143. The snap-fit ​​portion 141, connecting portion 142, and fixing portion 143 are at least partial structures of the snap-fit ​​member 14. The snap-fit ​​portion 141, connecting portion 142, and fixing portion 143 can be independent structures connected to each other, or they can be integrally formed and connected. As a specific example, in this embodiment, the snap-fit ​​portion 141 is generally a block structure, the connecting portion 142 is generally a strip structure, and the fixing portion 143 is generally a ring structure. The snap-fit ​​portion 141 and the fixing portion 143 are respectively connected to the two ends of the connecting portion 142, and the fixing portion 143 is located within the receiving cavity 101 and connected to the housing 10. The inner sidewall of the receiving groove 102 is provided with a clearance opening 1021 communicating with the receiving cavity 101, and the snap-fit ​​portion 141 passes through the clearance opening 1021 and protrudes into the receiving groove 102. The snap-fit ​​part 141 is a specific structure of the snap-fit ​​member 14 used to snap into the snap-fit ​​groove 131 on the electrical connector 13.

[0048] With the above configuration, during the process of inserting or pulling out the electrical connector 13 into the receiving groove 102, when the electrical connector 13 applies a sufficiently large external force to the locking part 141, the connecting part 142 of the locking member 14 can undergo elastic deformation so that the locking part 141 moves into or out of the locking groove 131, thereby locking the electrical connector 13 in the receiving groove 102 or allowing the electrical connector 13 to move freely out of the receiving groove 102.

[0049] In some embodiments, the snap-fit ​​member 14 further includes a support portion 144 disposed on the connecting portion 142, the support portion 144 protruding from the surface of the connecting portion 142 opposite to the receiving groove 102. Specifically, the support portion 144 is a block-shaped structure protruding relative to the connecting portion 142. The support portion 144 is used to cooperate with parts or components inside the housing 10, thereby limiting the deformation range of the snap-fit ​​member 14 and preventing the snap-fit ​​member 14 from being excessively bent and unable to recover. The support portion 144 and the snap-fit ​​portion 141 are respectively located on opposite sides of the connecting portion 142.

[0050] With the above configuration, when the clamping part 141 moves during the insertion or removal of the electrical connector 13 from the receiving groove 102, the support part 144 can resist other structures to limit the deformation of the clamping part 14, thereby protecting the clamping part 14.

[0051] In some embodiments, the housing 10 further includes a limiting portion (not shown) disposed within the receiving cavity 101. As a specific example, the limiting portion is disposed on the inner sidewall of the housing 10 and protrudes relative to the inner sidewall of the housing 10. The limiting portion can be any shape such as cuboid, cube, or cylinder. The support portion 144 is disposed at a distance from the limiting portion, and the distance between the support portion 144 and the limiting portion is not less than 0.5 mm and not more than 1.5 mm.

[0052] With the above settings, when the clamping part 141 moves during the insertion or removal of the electrical connector 13 from the receiving groove 102, the support part 144 will move towards the limiting part. By limiting the distance between the support part 144 and the limiting part, the deformation of the clamping part 14 can be limited, thereby preventing the clamping part 14 from bending excessively and extending the service life of the clamping part 14.

[0053] In some other embodiments, the support portion 144 contacts the limiting portion, and at least one of the support portion 144 and the limiting portion is elastic. It should be noted that "at least one of the support portion 144 and the limiting portion is elastic" includes the following situations: the support portion 144 is elastic but the limiting portion is not elastic; the support portion 144 is not elastic but the limiting portion is elastic; both the support portion 144 and the limiting portion are elastic.

[0054] With the above configuration, when the clamping part 141 moves during the insertion or removal of the electrical connector 13 from the receiving groove 102, the support part 144 will move towards the limiting part. Since at least one of the support part 144 and the limiting part is elastic, the above movement can occur smoothly. And since the support part 144 is in contact with the limiting part, the limiting part can limit the deformation of the clamping part 14, thereby preventing the clamping part 14 from bending excessively and extending the service life of the clamping part 14.

[0055] Please see Figure 6 and Figure 7 In some embodiments, the housing 10 further includes a baffle 105 disposed within the receiving cavity 101. The baffle 105 is generally plate-shaped and is disposed adjacent to the snap-fit ​​member 14, thereby preventing the snap-fit ​​member 14 from excessively shifting towards the side where the baffle 105 is located. As a specific example, in this embodiment, two baffles 105 are provided, and the connecting portion 142 is located between the two baffles 105. With the above arrangement, since the connecting portion 142 of the snap-fit ​​member 14 is located between the two baffles 105, the two baffles 105 can limit the connecting portion 142 to prevent the snap-fit ​​member 14 from shifting, thereby improving the stability and reliability of the snap-fit ​​member 14 installation, so as to ensure that the snap-fit ​​member 14 can stably engage with the electrical connector 13.

[0056] Please see Figure 3 and Figure 4 In some embodiments, the housing 10 further includes a stop portion 106 protruding from the inner wall of the receiving groove 102. The stop portion 106 is a block structure of any shape, such as a cube, cuboid, or irregular shape. The stop portion 106 is located on the side of the latching portion 141 away from the data cable 12. The electrical connector 13 is also provided with a stop groove 132, and the stop portion 106 can be selectively accommodated in the stop groove 132.

[0057] With the above configuration, when the electrical connector 13 is inserted into the receiving groove 102, the stop part 106 is located within the stop groove 132. The engagement between the stop part 106 and the stop groove 132 improves the stability of the electrical connector 13 within the receiving groove 102. When the electrical connector 13 is removed from the receiving groove 102, the stop part 106 also moves out of the stop groove 132, at which point the stop part 106 loses its holding and fixing function on the electrical connector 13. In summary, the stop part 106, in conjunction with the stop groove 132, further improves the stability of the electrical connector 13 when inserted into the receiving groove 102, thereby further reducing the possibility of the electrical connector 13 accidentally dislodging from the receiving groove 102 when the user pulls up the data cable 12.

[0058] In some embodiments, the stop groove 132 is connected to and communicates with the snap-fit ​​groove 131. The end of the stop groove 132 away from the snap-fit ​​groove 131 is open so that the stop part 106 can enter or exit the stop groove 132. The end of the stop groove 132 away from the snap-fit ​​groove 131 is provided with a guide surface 1321, which is used to guide the stop part 106 to move into the stop groove 132 when the electrical connector 13 is inserted into the receiving groove 102.

[0059] In some embodiments, guide surfaces 1321 are provided on the two opposing inner sidewalls of the stop groove 132, and the distance between the two guide surfaces 1321 near the end of the snap-fit ​​groove 131 is smaller than the distance between the two guide surfaces 1321 away from the end of the snap-fit ​​groove 131.

[0060] With the above configuration, during the process of inserting the electrical connector 13 into the receiving groove 102, when the stop part 106 is about to enter the stop groove 132, the end of the stop part 106 near the snap-fit ​​part 141 will first be between the two guide surfaces 1321. Since the distance between the ends of the two guide surfaces 1321 near the snap-fit ​​groove 131 is less than the distance between the ends of the two guide surfaces 1321 away from the snap-fit ​​groove 131, as the electrical connector 13 continues to move, the two guide surfaces 1321 can jointly guide the stop part 106 to move smoothly into the stop groove 132 relative to the electrical connector 13, thereby making it easier for the stop part 106 to enter the stop groove 132.

[0061] Please see Figure 3In some embodiments, the electrical connector 13 is inserted into the receiving groove 102 along the first direction X. It should be noted that "the electrical connector 13 is inserted into the receiving groove 102 along the first direction X" means that the electrical connector 13 can be inserted into the receiving groove 102 along the first direction X, or it can be moved out of the receiving groove 102 along the first direction X. The width of the stop portion 106 in the first direction X is greater than the width of the latching portion 141 in the first direction X. The width of the stop portion 106 in the second direction Y is less than the width of the latching portion 141 in the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0062] With the above configuration, since the width of the stop portion 106 in the first direction X is greater than the width of the latching portion 141 in the first direction X, the limiting effect of the latching portion 141 on the electrical connector 13 in the first direction X is better than that of the stop portion 106. Since the width of the stop portion 106 in the second direction Y is smaller than the width of the latching portion 141 in the second direction Y, the limiting effect of the stop portion 106 on the electrical connector 13 in the second direction Y is better than that of the latching portion 141. In summary, the latching portion 141 and the stop portion 106 jointly limit the electrical connector 13, which can simultaneously improve the stability of the electrical connector 13 in both the first and second directions Y after it is inserted into the receiving groove 102, thus reducing the possibility of the electrical connector 13 accidentally dislodging from the receiving groove 102 along either the first direction X or the second direction Y.

[0063] Please see Figures 1 to 4 In some embodiments, there are two data cables 12, two electrical connectors 13, two receiving slots 102, and two snap-fit ​​connectors 14. Two receiving slots 102 are arranged side-by-side between two snap-fit ​​connectors 14. Two electrical connectors 13 are respectively connected to two data cables 12, and each electrical connector 13 is detachably inserted into one of the two receiving slots 102. The two electrical connectors 13 can be of the same or different types. Two snap-fit ​​connectors 14 are respectively provided corresponding to the two receiving slots 102.

[0064] With the above configuration, since two data cables 12 are provided and the two receiving slots 102 are arranged side by side, when the two electrical connectors 13 on the two data cables 12 are respectively inserted into the two receiving slots 102 and respectively fixed in the two receiving slots 102 by the two snap-fit ​​pieces 14, the two data cables 12 are distributed side by side and can both be used as handles for the user to lift. Therefore, the two data cables 12 can distribute the pressure when the user lifts the data cables 12, further improving the anti-detachment effect of the electrical connectors 13. Furthermore, when one data cable 12 is used to charge an electronic device, the other data cable 12 can continue to be used as a handle for the user to lift. Moreover, the two data cables 12 can meet the user's need to charge two devices simultaneously, and when the types of electrical connectors 13 on the two data cables 12 are different, it can also meet the user's charging needs for electronic devices with different charging types.

[0065] Please see Figure 1 , Figure 8 and Figure 9 In some embodiments, the housing 10 includes a main housing 107 and a sub-housing 108. The main housing 107 is the main body of the housing 10, and its volume is larger than that of the sub-housing 108. The main housing 107 and the sub-housing 108 are connected to each other to form the housing 10. The main housing 107 is provided with a mounting port 1073 communicating with the receiving cavity 101. The sub-housing 108 is detachably connected to the main housing 107 and covers the mounting port 1073. The specific connection method between the main housing 107 and the sub-housing 108 can be through fasteners such as screws / bolts, or through snap-fit ​​connection using clips and slots. The specific connection method between the main housing 107 and the sub-housing 108 is not limited. A receiving groove 102 is provided on the sub-housing 108, specifically located on the side wall of the sub-housing 108 opposite to the receiving cavity 101. The power bank 100 also includes a reinforcing member 15 and an elastic insert 16. The reinforcing member 15 is a block structure, simultaneously sleeved on both data cables 12, and passes through the sub-housing 108. The reinforcing member 15 has a positioning groove 151, which is annular on the side wall of the reinforcing member 15 and located within the receiving cavity 101. The elastic insert 16 is approximately U-shaped (see...). Figure 10 The elastic insert is made of an elastic material, such as elastic rubber or elastic plastic. The elastic insert 16 is elastically held in the positioning groove 151 and fits against the surface of the sub-housing 108 facing the receiving cavity 101.

[0066] With the above configuration, when the data cable 12 malfunctions, maintenance personnel can remove the sub-shell 108 from the main shell 107, and then remove the elastic insert 16 from the positioning slot 151 of the reinforcement 15. This allows the reinforcement 15 to be separated from the sub-shell 108, facilitating the disassembly and replacement of the faulty data cable 12, thus simplifying the replacement process. Furthermore, the presence of the reinforcement 15 prevents the data cable 12 from directly contacting and rubbing against the shell 10 (specifically, the sub-shell 108), thereby protecting the data cable 12, reducing wear, and extending its lifespan.

[0067] Please see Figure 1 , Figure 8 , Figure 9 and Figure 11 In some embodiments, the main housing 107 includes a first half-shell 1071 and a second half-shell 1072 that interlock with each other, and the first half-shell 1071 and the second half-shell 1072 are detachably connected. The first half-shell 1071 and the second half-shell 1072 can be connected by fasteners such as screws / bolts, or they can be connected by snap-fitting with clips and slots. The specific connection method of the first half-shell 1071 and the second half-shell 1072 is not limited. The power assembly 11 includes a mounting bracket 111, which is a generally rectangular frame structure. The mounting bracket 111 is used to mount other structures of the power assembly 11. The mounting bracket 111 is detachably connected to one of the first half-shell 1071 and the second half-shell 1072. The mounting bracket 111 and the first half-shell 1071 / second half-shell 1072 can be connected by fasteners such as screws / bolts, or by snap-fit ​​connection using clips and slots. The specific connection method between the mounting bracket 111 and the first half-shell 1071 / second half-shell 1072 is not limited. The mounting bracket 111 has a mounting part 103, and the sub-shell 108 has a positioning part 1081 on its side wall opposite to the receiving groove 102. The fixing part 143 of the snap-fit ​​member 14 is located between the mounting part 103 and the positioning part 1081. As a specific example, the positioning part 1081 has a threaded hole. Screws pass through the mounting part 103 and the fixing part 143 of the snap-fit ​​member 14 and are threaded into the threaded hole to achieve a fixed connection between the mounting part 103 of the mounting bracket 111, the fixing part 143 of the snap-fit ​​member 14, and the positioning part 1081 of the sub-shell 108.

[0068] With the above settings, when assembling the power bank 100, the staff can achieve the fixed connection of the mounting bracket 111, the snap-fit ​​component 14 and the sub-shell 108 in one operation (connecting the screw to the positioning part 1081). This not only simplifies the assembly steps and improves the assembly efficiency, but also helps to improve the stability of the mounting bracket 111, the snap-fit ​​component 14 and the sub-shell 108.

[0069] In some embodiments, the power assembly 11 includes an electrically connected battery 112, a first circuit board 113, and a second circuit board 114. A mounting slot 115 is provided on one side of the mounting bracket 111, and the battery 112 is housed within the mounting slot 115. The first circuit board 113 is disposed on the mounting bracket 111 and located on the side of the mounting bracket 111 opposite to the mounting slot 115. The first circuit board 113 can be fixedly connected to the mounting bracket 111 by bolts / screws. The second circuit board 114 is disposed on the mounting bracket 111 and located on the side of the mounting bracket 111 opposite to the mounting slot 115, and the second circuit board 114 can be fixedly connected to the mounting bracket 111 by bolts / screws. The plane of the second circuit board 114 is perpendicular to the plane of the first circuit board 113.

[0070] With the above configuration, the assembly process of the power bank 100 is as follows: First, the battery 112 is installed in the mounting slot 115 of the mounting bracket 111, and the first circuit board 113 and the second circuit board 114 are both installed on the mounting bracket 111; then, the mounting bracket 111, the snap-fit ​​component 14, and the sub-shell 108 are fixedly connected with screws to form an integrated module structure; finally, the mounting bracket 111 is installed on the first half-shell 1071 / second half-shell 1072, and the first half-shell 1071 and the second half-shell 1072 are fastened together to form the main shell 107. The above assembly process is convenient and quick, which helps to improve the production efficiency of the power bank 100. Furthermore, the above configuration also allows for a reasonable layout of the various components that make up the power assembly 11, thereby reducing the space occupied by the power assembly 11 and thus reducing the size of the power bank 100.

[0071] Please continue reading. Figure 1 , Figure 8 and Figure 9 In some embodiments, the power bank 100 further includes an indicator light 17 and a charging interface 18. Both the indicator light 17 and the charging interface 18 are disposed on the housing 10 and opposite to the second circuit board 114. Specifically, the indicator light 17 and the charging interface 18 are disposed on the sub-housing 108. The indicator light 17 is electrically connected to the second circuit board 114, and the charging interface 18 is electrically connected to both the second circuit board 114 and the battery 112. The charging structure is used to connect to the charger of the power bank 100 to charge the battery 112 inside the power bank 100. The indicator light 17 illuminates when the power bank 100 is charging, serving as a charging indicator.

[0072] With the above configuration, since both the indicator light 17 and the charging interface 18 are positioned opposite to and electrically connected to the second circuit board 114, the wiring distance between the indicator light 17 and the second circuit board 114 can be shortened, as can the wiring distance between the charging interface 18 and the second circuit board 114. This helps to reduce the size of the power bank 100, making it easier for users to carry and store the power bank 100.

[0073] In some embodiments, the power assembly 11 further includes a protective layer 116, which is an elastic material layer, such as a rubber layer, a silicone layer, or a cotton cloth layer. The protective layer 116 is disposed on the inner sidewall of the housing 10 and is held together by the housing 10 and the battery 112. The protective layer 116 and the housing 10 can be fixed by adhesive or by snap-fit, and the specific connection method between the protective layer 116 and the housing 10 is not limited.

[0074] With the above-mentioned configuration, the protective layer 116 can protect the battery 112 and provide a certain amount of expansion space for the battery 112. In addition, the housing 10, together with the protective layer 116 and the mounting bracket 111, can further improve the stability of the battery 112 installation, so as to ensure that the power supply assembly 11 can work stably.

[0075] Please see Figure 12 and Figure 13 In some embodiments, the snap-fit ​​element 14 is a spring sheet, meaning that the snap-fit ​​element 14 is made of a resilient sheet-like structure, such as a plastic spring sheet or a metal spring sheet. At least a portion of the structure of the snap-fit ​​element 14 is bent to form a snap-fit ​​portion 141, and at least a portion of the structure of the snap-fit ​​element 14 is located within the receiving cavity 101 and fixedly connected to the housing 10. For example, the snap-fit ​​element 14 and the housing 10 can be fixedly connected by fasteners such as bolts / screws, or the snap-fit ​​connection can be achieved by setting a buckle and a slot. The inner sidewall of the receiving groove 102 is provided with a relief opening 1021 communicating with the receiving cavity 101, and the snap-fit ​​portion 141 passes through the relief opening 1021 and protrudes into the receiving groove 102.

[0076] With the above configuration, since the snap-fit ​​portion 141 of the snap-fit ​​member 14 is elastic, when the electrical connector 13 is inserted into the receiving groove 102, the snap-fit ​​portion 141 of the snap-fit ​​member 14 can elastically abut against the inner bottom wall of the snap-fit ​​groove 131 to achieve snap-fit ​​fixation of the electrical connector 13. Furthermore, when the user forcefully pulls out the electrical connector 13, the snap-fit ​​portion 141 can disengage from the snap-fit ​​groove 131, thus losing its fixing effect on the electrical connector 13, facilitating user operation.

[0077] In some embodiments, the latching portion 141 of the latching member 14 is located in the middle position of the latching member 14, and the portions at both ends of the latching member 14 are located within the receiving cavity 101 and fixedly connected to the housing 10. With this arrangement, since both ends of the latching member 14 are fixedly connected to the housing 10, and the latching portion 141 is located in the middle position of the latching member 14, it is beneficial to improve the stability of the connection between the latching member 14 and the housing 10, and to reduce the impact of the latching portion 141 on the latching member 14 when it moves.

[0078] In summary, the embodiments of this application provide a power bank 100, which allows the electrical connector 13 to be inserted into the receiving slot 102 so that the data cable 12 forms a handle for the user to lift. Because of the snap-fit ​​connector 14 and the snap-fit ​​slot 131, the snap-fit ​​connector 14 can stably insert the electrical connector 13 into the receiving slot 102, minimizing the risk of the electrical connector 13 accidentally dislodging from the receiving slot 102 when the user lifts the data cable 12. Therefore, it can improve the safety and reliability of the user when lifting the power bank 100 using the data cable 12, thereby making it more convenient for the user to carry the power bank 100 and improving the user experience.
