[0034] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0035] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0036] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0037] As an energy storage device, a mobile power source can charge portable electronic devices. With the rapid development of portable electronic devices, they can be charged wirelessly based on electromagnetic induction. Therefore, some mobile power sources have a wireless charging function. Such mobile power sources with a wireless charging function are usually attached to the back of the electronic device by magnetic attraction. For the convenience of users, some mobile power sources are usually provided with a bracket for support. However, in existing mobile power sources, the bracket and the active component are usually connected in the following two ways:

[0038] First, the bracket is connected to the rotating part through a circlip, which requires professional circlip pliers to install during the installation process. After installation, it needs to be destructively disassembled and cannot be repaired;

[0039] Second, the rotating part is fixed to the rotating part by a plastic spring arm buckle, which reduces the strength and makes disassembly difficult, which can easily lead to the scrapping of the rotating part.

[0040] Particularly, in the following embodiments, the electronic device is a portable electronic device, such as a mobile phone, a tablet computer, etc.

[0041] See also Figure 1-Figure 5As shown, the mobile power provided in the present application includes: a housing 10 , a battery cell 20 , a power output unit 30 , a bracket 40 and a damping rotation assembly 50 .

[0042] The shell 10 is an installation structure of other structures. The shell 10 has an installation cavity 100 inside, and the battery cell 20 is fixed in the installation cavity 100. The front of the shell 10 is provided with a connecting portion 101 for connecting to a device to be charged.

[0043] In this embodiment, the connecting portion 101 can connect the shell 10 to the back of the device to be charged. For example, the connecting portion 101 can be connected to the device to be charged by clamping, magnetism, adhesion, etc. Please refer to the subsequent embodiments for details.

[0044] The battery cell 20 can charge the device to be charged. In some embodiments, the battery cell 20 can charge the device to be charged by charging cable connection or electromagnetic induction wireless charging, etc., please refer to the subsequent embodiments for details.

[0045] In order to facilitate the battery cell 20 in the mobile power supply to charge the charging device, see Figure 5 As shown, the mobile power provided in this embodiment also includes: a power output unit 30, wherein the power output unit 30 is arranged in the shell 10, the input end of the power output unit 30 is connected to the battery cell 20, and the output end of the power output unit 30 is used to be electrically connected to the device to be charged, so that the power of the battery cell 20 can be transmitted to the device to be charged.

[0046] The damping rotation assembly 50 includes: a fixed member 51, a rotating member 52 and a damping component 53. The fixed member 51 is fixedly connected to the housing 10, the rotating member 52 is rotatably connected to the fixed member 51, and the damping component 53 is arranged between the rotating member 52 and the fixed member 51. The damping component 53 is used to provide damping to the rotating member 52 so that the rotating member 52 can be maintained at any rotation position. The bracket 40 is connected to the rotating member 52 to change the angle between the bracket 40 and the back of the housing 10 through the rotating member 52.

[0047] like Figure 3 and Figure 4 As shown, the rotating member 52 can keep rotating relative to the fixed member 51. For example, a screw rod 511 is provided on the fixed member 51, and a screw hole 522 is provided on the rotating member 52. The screw rod 511 is screwed into the screw hole 522 so that the rotating member 52 is connected to the fixed member 51 in a manner of rotating relative to the fixed member 51, and a damping component 53 is provided between the rotating member 52 and the fixed member 51.

[0048] It can be understood that in order to provide damping through the damping component 53 when the rotating member 52 rotates, so that it can be maintained at any rotation position, in this embodiment, the damping component 53 can be made of materials such as silicone, rubber, etc., and the rotating member 52 and the fixed member 51 squeeze the damping component 53, so that the damping component 53 is squeezed and deformed, so that the rotating member 52 can generate friction with the damping component 53 during the rotation process. The friction force is the damping force of the rotating member 52, and can keep the rotating member 52 at any position after rotating to that position.

[0049] It should be noted that, when the rotating member 52 and the fixed member 51 are screwed to the screw hole 522 through the screw rod 511, a certain gap is reserved between the rotating member 52 and the fixed member 51. The width of the gap should be smaller than the thickness of the damping component 53, so that the damping component 53 can be squeezed to generate damping.

[0050] The bracket 40 is connected to the rotating member 52, so the bracket 40 can rotate synchronously with the rotating member 52. During the rotation process, since the rotating member 52 rotates relative to the fixed member 51 and can be maintained at any rotation position by the damping member 53, the bracket 40 can be rotated steplessly. In order for the bracket 40 to form a support, it is necessary to form a certain angle between the bracket 40 and the back of the housing 10. Here, it should be noted that in order for the bracket 40 to rotate synchronously with the rotating member 52 and to form a certain angle with the back of the housing 10 during the rotation process, the rotating member 52 can be set on the back or side of the housing 10.

[0051] In this embodiment, the damping rotation assembly 50 is disposed on the side of the housing 10. Figure 3 , Figure 5 and Figure 6 As shown, the bracket 40 has a support portion 41, a first arm portion 42 and a second arm portion 43, wherein the first arm portion 42 and the second arm portion 43 are respectively connected to the support portion 41 to form a U-shaped, Y-shaped or π-shaped bracket 40. The first arm portion 42 is fixedly connected to the rotating member 52, and the second arm portion 43 is rotatably connected to the housing 10.

[0052] In a specific embodiment, a locking portion 421 is provided at the end of the first arm portion 42 away from the support portion 41, a shaft 431 is provided at the end of the second arm portion 43 away from the support portion 41, and an exposure hole 102 and a shaft hole 103 are respectively provided on two opposite side surfaces of the housing 10, and a fixing portion 104 is further provided inside the housing 10, a fixing member 51 is fixed to the fixing member 104, a rotating member 52 is passed through the exposure hole 102 and fixedly connected to the locking portion 421, and a shaft 431 is rotatably mounted on the shaft hole 103. Since the locking portion 421 is fixedly connected to the rotating member 52, the first arm portion 42 is indirectly connected to the rotating member 52, so that the rotating rotating member 52 drives the first arm portion 42 to rotate synchronously and drives the support portion 41 to rotate, and the cooperation between the shaft 431 on the second arm portion 43 and the shaft hole 103 can ensure the stability of the rotation of the bracket 40.

[0053] In practical applications, when the bracket 40 is synchronously driven to rotate by the rotating member 52 and changes the angle between the bracket 40 and the back surface of the housing 10 , the bracket 40 is supported on a plane by the supporting portion 41 , thereby forming support for the mobile power supply.

[0054] In order to ensure the stability of the second arm 43 during the rotation process, Figure 3 and Figure 5 As shown, an axial limiting portion 432 is provided on the shaft rod 431, and an axial limiting fitting portion 105 and a radial limiting fitting portion 106 are also provided inside the shell 10. The axial limiting fitting portion 105 cooperates with the axial limiting portion 432 to limit the axial movement of the shaft rod 431, and the radial limiting fitting portion 106 cooperates with the shaft rod 431 to limit the radial movement of the shaft rod 431.

[0055] In the above-mentioned embodiment, the axial limiting fitting portion 105 is a limiting plate arranged inside the shell 10. By means of the limiting plate stopping the axial limiting portion 432, the axial displacement of the shaft rod 431 can be limited to avoid axial movement during rotation. The radial limiting fitting portion 106 is an avoidance groove arranged on the limiting plate. By means of the avoidance groove avoiding the shaft rod 431, the shaft rod 431 can be accommodated in the avoidance groove, thereby limiting the radial displacement of the shaft rod 431 to avoid radial movement during rotation.

[0056] In one embodiment of the present application, one end of the shaft 431 away from the second arm 43 abuts against the battery cell 20. In order to avoid damage to the battery cell 20 during the rotation process, the mobile power supply provided in this embodiment also includes: a partition component 60, which is at least arranged between the axial limit portion 432 of the shaft 431 and the battery cell 20 to protect the battery cell 20.

[0057] It is understandable that if the end of the shaft 431 away from the second arm 43 does not abut the battery cell 20, the partition component 60 may not be provided. Of course, if the shaft 431 abuts other electronic devices, the partition component 60 may also be used for protection.

[0058] In a specific embodiment, the shaft 431 may be a wear-resistant structure made of rubber or silicone material, which is not limited here and can be selected according to actual needs.

[0059] See also Figure 6 As shown, the locking portion 421 is a mounting groove 422 provided on the first arm portion 42, the rotating member 52 is installed in the mounting groove 422, and the rotating member 52 is tightly matched with the mounting groove 422. The mounting groove 422 is provided with a first limiting unit 423, and the rotating member 52 is provided with a second limiting unit 521, and the first limiting unit 423 cooperates with the second limiting unit 521 to keep the bracket 40 and the rotating member 52 rotating synchronously.

[0060] In this embodiment, the mounting groove 422 is a blind hole arranged at one end of the first arm portion 42 away from the supporting portion 41, and the first limiting unit 423 is a plane arranged in the blind hole. Accordingly, the rotating member 52 adopts a columnar structure, and the second limiting unit 521 is a planar mating surface arranged on the circumference of the rotating member 52 of the columnar structure. The planes and the planar mating surfaces cooperate with each other, so that the bracket 40 can keep synchronous rotation with the rotating member 52.

[0061] In one embodiment, the power output unit 30 may be at least one of a wired charging module and a wireless charging module, wherein the wired charging module may be an interface (e.g., a Type-C interface), which can be connected to the interface and the device to be charged via a charging cable. The wireless charging module may be charged by electromagnetic induction, and accordingly, the device to be charged is a module with a wireless charging function.

[0062] Continue to see Figure 5 As shown, the power output unit 30 includes: a coil 31, a magnet 32 ​​and a transmitter (not shown in the figure), wherein the coil 31 is electrically connected to the battery core 20, the magnet 32 ​​is placed in the electromagnetic wire generated by the coil 31, and the transmitter is connected to the magnet 32. The battery core 20 can be converted into alternating current through a conversion module, and the alternating current is provided to the coil 31, so that the coil 31 generates an alternating magnetic field, and the alternating magnetic field signal can be transmitted to the receiving coil of the device to be charged through the transmitter, so as to achieve the purpose of wireless charging.

[0063] In the present application, the connection part 101 can be used to fix the housing 10 to the back of the device to be charged by pasting, clamping, etc., so as to facilitate use. In this embodiment, the connection part 101 is a magnetic attraction structure 1011 arranged on the front of the housing 10, and the magnetic attraction structure 1011 is used to be adsorbed to the device to be charged by magnetic attraction.

[0064] To facilitate the installation of various components inside the shell 10, in this embodiment, the shell 10 includes a bottom shell 11 and an upper cover 12, and the upper cover 12 is connected to the bottom shell 11 to form an installation cavity 100. The shell 10 formed by the split design of the bottom shell 11 and the upper cover 12 can facilitate the installation and maintenance of various internal components.

[0065] The present application also provides a mobile power source, which is different from the mobile power source in the above-mentioned embodiment in that the bracket in the mobile power source provided by the present application can be rotated to a preset rotation position in a stepless manner.

[0066] See also Figure 7-Figure 10 As shown, the mobile power supply provided in this embodiment includes: a shell 10, a battery cell 20, a bracket 40 and a damping rotation assembly 50. The shell 10 has an installation cavity 100 inside, and the battery cell 20 is fixed in the installation cavity 100. The front of the shell 10 is provided with a connecting portion for connecting to a device to be charged, so as to connect to the device to be charged, thereby charging the device to be charged through the battery cell 20.

[0067] The damping rotation assembly 50 includes: a fixed member 51, a rotating member 52, a damping component 53 and a limiting component 54. The fixed member 51 is fixedly connected to the housing 10, the rotating member 52 is rotatably connected to the fixed member 51, and the damping component 53 is arranged between the rotating member 52 and the fixed member 51. The damping component 53 is used to provide damping to the rotating member 52 so that the rotating member 52 can be maintained at any rotation position. The bracket 40 is connected to the rotating member 52 to change the angle between the bracket 40 and the back of the housing 10 through the rotating member 52.

[0068] The rotating member 52 can keep rotating relative to the fixed member 51. For example, a screw rod 511 is provided on the fixed member 51, and a screw hole 522 is provided on the rotating member 52. The screw rod 511 is screwed into the screw hole 522 so that the rotating member 52 is connected to the fixed member 51 in a manner of rotating relative to the fixed member 51, and a damping member 53 is provided between the rotating member 52 and the fixed member 51.

[0069] It can be understood that in order to provide damping through the damping component 53 when the rotating member 52 rotates, so that it can be maintained at any rotation position, in this embodiment, the damping component 53 can be made of materials such as silicone, rubber, etc., and the rotating member 52 and the fixed member 51 squeeze the damping component 53, so that the damping component 53 is squeezed and deformed, so that the rotating member 52 can generate friction with the damping component 53 during the rotation process. The friction force is the damping force of the rotating member 52, and can keep the rotating member 52 at any position after rotating to that position.

[0070] It should be noted that, when the rotating member 52 and the fixed member 51 are screwed to the screw hole 522 through the screw rod 511, a certain gap is reserved between the rotating member 52 and the fixed member 51. The width of the gap should be smaller than the thickness of the damping component 53, so that the damping component 53 can be squeezed to generate damping.

[0071] The bracket 40 is connected to the rotating member 52, so the bracket 40 can rotate synchronously with the rotating member 52. During the rotation process, since the rotating member 52 rotates relative to the fixed member 51 and can be maintained at any rotation position by the damping member 53, the bracket 40 can be rotated steplessly. In order for the bracket 40 to form a support, it is necessary to form a certain angle between the bracket 40 and the back of the housing 10. Here, it should be noted that in order for the bracket 40 to rotate synchronously with the rotating member 52 and to form a certain angle with the back of the housing 10 during the rotation process, the rotating member 52 can be set on the back or side of the housing 10.

[0072] See also Fig.10 As shown, the limiting component 54 is fixed to the rotating member 52, and the housing 10 is provided with a first limiting matching portion 107 and a second limiting matching portion 108. The first limiting matching portion 107 matches with the limiting component 54, so that the angle between the bracket 40 and the back of the housing 10 is a first preset angle through the rotating member 52. The second limiting matching portion 108 matches with the limiting component 54, so that the angle between the bracket 40 and the back of the housing 10 is a second preset angle through the rotating member 52.

[0073] In a specific embodiment, a limiting protrusion 541 is provided on the limiting component 54. When the rotating member 52 rotates relative to the fixing member 51, the limiting protrusion 541 is blocked by the first limiting matching portion 107, so that the rotating member 52 drives the bracket 40 to rotate until the angle between the bracket 40 and the back of the housing 10 is the first preset angle. Under the first preset angle, the bracket 40 can be in Figure 1 and Figure 2 When the rotating member 52 rotates relative to the fixing member 51, the limiting protrusion 541 is blocked by the second limiting matching portion 107, so that the rotating member 52 drives the bracket 40 to rotate until the angle between the rotating member 52 and the back of the housing 10 is the second preset angle. Under the second preset angle, the bracket 40 can be in Figure 1 and Figure 2 The outer side of the housing 10 is shown.

[0074] It should be noted that the bracket 40 can remain stationary at any position between the first preset angle and the second preset angle driven by the rotating member 52, so that the position between the bracket 40 and the back of the housing 10 can be adjusted. When the device to be charged is connected to the front of the housing 10 through the connecting portion, the supporting angle of the bracket 40 to the housing 10 can be appropriately adjusted for user convenience.

[0075] To sum up, in the mobile power supply provided in this embodiment, the bracket can rotate synchronously with the rotating part. During the rotation process, since the rotating part rotates relative to the fixed part and can be maintained at any rotation position by the damping component, while realizing stepless rotation, the bracket and the back side of the shell can form a certain angle, and then the mobile power supply is supported by the bracket to facilitate user use.

[0076] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
