Detailed implementation

[0026] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments described in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, top, bottom) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, the term "perpendicular" involved in the embodiments and claims of the present utility model means that the included angle between two elements is 90° or there is a deviation of -5° to +5°, and the term "parallel" involved means that the included angle between two elements is 0° or there is a deviation of -5° to +5°.

[0028] In the embodiments of the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0029] As Figures 1-5 shown, a power bank 1 provided by an embodiment of the present utility model. The power bank 1 includes, for example, a main body 10 and a first frame 20. Among them, the power bank 1 is used to provide a charging power source for electronic devices such as mobile phones and tablet computers. The power bank 1 is, for example, a power bank, and the main body 10 is, for example, the body part of the power bank 10. The main body 10 can be, for example, a square power bank or Figure 1The cylindrical power bank shown here does not limit the shape of the main body 10. For example, it includes a housing, and an internal electronic circuit is provided inside the housing, etc. The first frame 10 is, for example, a hanging structure or a locking structure.

[0030] Specifically, the mobile power supply 1 includes a main body 10 and a first frame 20 connected to the main body 10; one end of the first frame 20 is rotatably connected to the main body 10, and a first magnetic member 31 is provided at the other end of the first frame 20, and a second magnetic member 32 corresponding to the first magnetic member 31 is provided on the main body 10. The first magnetic member 31 can be magnetically connected to the second magnetic member 32 to form a closed-loop hanging space 60. The closed-loop hanging space 60 allows the user to hang the mobile power supply on the waist or on the user's pants, etc., making the hanging more secure.

[0031] The first frame 20 is rotatably connected to the main body, which facilitates the closing or separation between the other end of the first frame 20 and the main body 10. When the other end of the first frame 20 rotates above the second magnetic member 32, due to the magnetic attraction between the first magnetic member 31 and the second magnetic member 31, a hanging space 60 is formed between the first frame 20 and the main body 10 to complete the hanging of the mobile power supply 1. When the mobile power supply 1 needs to be taken out, the user can rotate the first frame 20 with one hand to separate the first magnetic member 31 and the second magnetic member 31, so that the mobile power supply 1 can be taken out conveniently.

[0032] Among them, the first magnetic member 31 is, for example, a magnetic attracting member or a magnet, and the second magnetic member 32 is a magnetic attracting member or a ferromagnetic metal member matching the first magnetic member 31. The second magnetic member 240 and the first magnetic member 230 are magnetically connected to realize the stable connection of the hanging structure 200.

[0033] In the embodiment of the present invention, the first frame 20 is rotatably connected to the main body 10, and a first magnetic member 31 is provided at one end of the first frame 20, and a second magnetic member 32 corresponding to the first magnetic member 31 is provided on the main body 10. Through the magnetic connection between the first magnetic member 31 and the second magnetic member 32, a hanging space 60 is formed between the first frame 20 and the main body 10, which can facilitate the user to carry and hang the mobile power supply 1 on a body part such as the waist. In addition, the magnetic connection between the first magnetic member 31 and the second magnetic member 32 can ensure that after the mobile power supply 1 is used multiple times, the magnetic connection between the first magnetic member 31 and the second magnetic member 32 will not produce a dry feeling and will not affect the wearing and use. Moreover, the user can conveniently use one hand to operate the opening and closing of the hanging space of the mobile power supply 1, improving the user's sense of use and experience.

[0034] Furthermore, as Figure 4As shown, a first connection structure 33 is provided on the main body portion 10. The first connection structure 33 is connected to the second magnetic member 32, and the first connection structure 33 can move the second magnetic member 32 closer to or farther away from the first magnetic member 31; and / or, a second connection structure 34 is provided on the first frame 20. The first magnetic member 31 is connected to the second connection structure 34, and the second connection structure 34 can move the first magnetic member 31 closer to or farther away from the second magnetic member 32. The first connection structure 33 and the second connection structure 34 have the same structure. Understandably, the first connection structure 33 and the second connection structure 34 are respectively provided on the main body portion 10 and the first frame 20 and are respectively connected to the second magnetic member 32 and the first magnetic member 31; in other embodiments, the first connection structure 33 can also be provided on the main body portion 10 to connect the second magnetic member 32, the first magnetic member 31 is directly provided on the first frame 20, or the second connection structure 34 is provided on the first frame 20 to connect the first magnetic member 31; the second magnetic member 32 is directly provided on the main body portion 10, and this is not limited uniquely here.

[0035] Specifically, the first connection structure 33 may, for example, include a receiving cavity 331. The second magnetic member 32 is disposed in the receiving cavity 331, and the second magnetic member 32 can move within the receiving cavity 331, for example, move up and down within the receiving cavity 331. When the second magnetic member 32 is magnetically connected to the first magnetic member 31, the second magnetic member 32 can move from the bottom of the receiving cavity 331 to the top of the receiving cavity 331 under the magnetic connection. When the first magnetic member 31 moves away from the second magnetic member 31, due to the lack of magnetic force and the action of its own gravity, the second magnetic member 32 moves from the top of the receiving cavity 331 to the bottom of the receiving cavity 331. Alternatively, the first connection structure 33 includes an elastic member 332. One end of the elastic member 332 is connected to the main body portion 10, and the other end of the elastic member 332 is connected to the second magnetic member 32. The elastic member 332 is, for example, a spring. One end of the spring can be fixedly connected to the main body portion 10, and the other end of the spring is fixedly connected to the second magnetic member 32. When the second magnetic member 32 is magnetically connected to the first magnetic member 31, the second magnetic member 32 can move closer to and connect to the first magnetic member 31 under the action of the magnetic force, and stretch the spring so that the spring is in a tensioned state. When the first magnetic member 31 moves away from the second magnetic member 31, due to the lack of magnetic force and the elastic force of the spring, the second magnetic member 32 is restored to its original position by the pulling force of the spring.

[0036] Specifically, as Figure 6 and Figure 7As shown, the first connection structure 33 may include, for example, a receiving cavity 331 and an elastic member 332 connected to the second magnetic member 32. The elastic member 332 and the second magnetic member 32 are disposed within the receiving cavity 331. That is, the first connection structure 33 may be provided with only a receiving cavity, or an elastic member, or a combined structure of a receiving cavity and an elastic member according to actual circumstances, and specific details are not limited here. The specific composition of the second connection structure 33 is similar to that of the first connection structure 33, and will not be elaborated here.

[0037] Furthermore, as Figure 6 and Figure 7 shown, a through hole 3311 is provided in the top wall of the receiving cavity 331 close to the first magnetic member 31. At least a part of the second magnetic member 32 passes through the through hole 3311 and abuts against the first magnetic member 31. By providing the through hole 3311, a part of the second magnetic member can be exposed outside the through hole 3311, so that after the second magnetic member 32 is separated from the first magnetic member 31, the second magnetic member 31 will not move together with the first magnetic member 31 due to the action of the magnetic force. And it makes the magnetic connection between the first magnetic member 31 and the second magnetic member 32 smoother, improving the user experience.

[0038] Even further, as Figure 7 shown, the second magnetic member 32 includes a contact portion 321 and a connecting portion 322. The connecting portion 322 is connected to the elastic member 332. The cross-sectional area of the connecting portion 322 is larger than the cross-sectional areas of the contact portion 321 and the through hole 3311. The through hole 3311 is adapted to the contact portion 321, and the contact portion 321 can movably pass through the through hole 3311, while the connecting portion 322 cannot pass through the through hole 3311 to limit the second magnetic member 32. The contact portion 321 is, for example, a magnet, and the connecting portion 332 is, for example, a limiting post. The size of the cross-section of the connecting portion 322 is larger than the size of the cross-section of the contact portion 321. This is set to prevent the contact portion 321 from detaching from the through hole 3311 and exposing the contact portion 321 outside the through hole 3311, thus destroying the locking structure of the magnetic connection.

[0039] Even further. The length of the receiving cavity 331 is greater than the length of the connecting portion 322. This is set to enable the connecting portion 322 to move within the receiving cavity 331 and also prevent the contact portion 321 from being completely exposed outside the through hole 3311. And / or, the elastic member 332 is disposed around the connecting portion 322. The elastic member 332 is disposed around the connecting portion 322, so that when the mobile power supply 1 is hung, the elastic member 332 can provide a uniform elastic force to the second magnetic member 32, making the second magnetic member 32 move faster in the receiving cavity 331 in the direction close to the main body portion 10, facilitating the next hanging of the mobile power supply 1.

[0040] As Figure 5As shown, one end of the first magnetic member 31 close to the second magnetic member 32 is provided with a first connection surface 311, and one end of the second magnetic member 32 away from the main body portion 10 is provided with a second connection surface 323 corresponding to the first connection surface 311. One of the first connection surface 311 and the second connection surface 323 is a convex surface, and the other is a concave surface. The matching design of the convex surface and the concave surface makes the first magnetic member 31 and the second magnetic member 32 more firmly magnetically connected, reducing the risk of accidental opening.

[0041] As Figure 3 and Figure 4 shown, the first frame 20 includes an arc portion 201, a first straight portion 202 and a second straight portion 203. The two ends of the arc portion 201 are respectively connected to the first straight portion 202 and the second straight portion 203. The first straight portion 202 is rotatably connected to the main body portion 10, and the second straight portion 203 is provided with a first magnetic member 31. The second straight portion 203 can rotate relative to the main body portion 10 to magnetically connect with the second magnetic member 32. Among them, the arc portion 201 is a connecting rod portion with one end bent, and the first straight portion 202 and the second straight portion 203 are a section of vertical connecting rod portion. By setting the structure of the first frame 20, the stability and durability of the connection between the first magnetic member 31 and the second magnetic member 32 in the mobile power supply 1 can be enhanced, and at the same time, setting the arc portion can improve the aesthetic degree of the product of the mobile power supply 1.

[0042] As Figure 3 shown, the first straight portion 202 and the second straight portion 203 are connected to the two ends of the maximum radial distance on the horizontal plane of the main body portion 10. It can be understood that the first straight portion 202 and the second straight portion 203 are arranged on the periphery of the main body portion 10 to form a maximum closed-loop hanging space 60 for the convenience of users to hang. The horizontal distance L1 between the first straight portion 202 and the second straight portion 203 does not exceed the maximum radial distance L2 of the horizontal plane of the main body portion. By limiting the horizontal distance between the first straight portion 202 and the second straight portion 203, the structure of the first frame 20 will not be arranged outside the main body portion 10.

[0043] As Figure 2 and Figure 4As shown, in an embodiment of the present utility model, the mobile power supply 1 further includes a rotating member 35, and the rotating member 35 is respectively connected to the first straight portion 202 of the first frame body 20 and the main body portion 10; the rotating member 35 is, for example, a rotating shaft. The rotating member 35 can be fixedly connected to the first frame body 10, and the rotating member 35 is rotatably connected to the main body portion 10, so as to drive the first frame body 10 to rotate, so that the first magnetic member 31 is separated from or connected to the second magnetic member 32. Of course, in other embodiments, the rotating member 35 can be rotatably connected to the first frame body 10, and the rotating member 35 is fixedly connected to the main body portion 10, and the first frame body 20 can also be rotated relative to the main body portion 10.

[0044] The main body portion 10 further includes a base portion and a second frame body 40 provided on the base portion, and the second frame body 40 is connected to the first straight portion 202; the second frame body 40 is respectively connected to the rotating member 35 and the base portion. The second frame body 40 can be arranged at one end of the main body portion 10 and relatively far from the first connection structure 33. The first connection structure 33 can also be, for example, a frame structure and is arranged corresponding to the second frame body 40 to improve the aesthetics of the product and the user experience.

[0045] In addition, it can be understood that the foregoing embodiments are only exemplary descriptions of the present utility model. On the premise that the technical features do not conflict, the structures are not contradictory, and the utility model purpose of the present utility model is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
