The bracket 14 is arranged on the side of the cover plate 20 away from the installation space 32, and the wireless charging coil 38 and the magnetic suction component 42 are arranged in the installation space 32 near the bottom plate 24.

[0029] The side of the bottom plate 24 facing away from the installation space 32 forms a charging surface 44. When the mobile phone is wirelessly charged, the mobile phone can be fixed to the charging surface 44 by magnetically cooperating with the magnetic component 42 through its own magnet array. The present application provides the mobile power 10 with the function of wireless charging by providing the wireless charging coil 38, and the mobile power 10 can be magnetically cooperating with the mobile phone and other accessories by providing the magnetic component 42, thereby increasing the convenience of use and bringing convenience to the user.

[0030] The wireless charging coil 38 is arranged close to the charging surface 44, and a magnetic shielding member 46 is provided on the side of the wireless charging coil 38 facing away from the charging surface 44. The magnetic shielding member 46 is located between the wireless charging coil 38 and the power supply 34. Since the wireless charging coil 38 generates a magnetic field when working, the magnetic shielding member 46 can be provided to effectively prevent the magnetic field generated by the wireless charging coil 38 from causing signal interference to the components of the circuit board 36.

[0031] In the illustrated embodiment, the magnetic attraction component 42 is disposed at the periphery of the wireless charging coil 38. Specifically, the magnetic attraction component 42 includes a first portion and a second portion that are spaced apart. The first portion is arranged in a ring shape, and the second portion is located on one side of the first portion and arranged along a straight line. The wireless charging coil 38 is located in the ring space of the first portion. A first accommodating portion 48 is provided on one side of the bottom plate 24 located in the installation space 32 corresponding to the magnetic attraction component 42. The first accommodating portion 48 is, for example, a groove structure. Due to the compact internal structure of the installation space 32, the first accommodating portion 48 is recessed from the inner wall of the housing 12 toward the charging surface 44, thereby making the first accommodating portion 48 protrude from the charging surface 44. The magnetic attraction component 42 is accommodated in the first accommodating portion 48. For example, the magnetic attraction component 42 is fixed in the first accommodating portion 48 by gluing or the like. A second accommodating portion 50 is provided on one side of the bottom plate 24 located in the installation space 32, corresponding to the wireless charging coil 38. The second accommodating portion 50 is located in the annular portion of the first accommodating portion 48 and the two are separated by a partition wall. The second accommodating portion 50 is, for example, a groove structure, and the wireless charging coil 38 is accommodated in the second accommodating portion 50. Preferably, the distance between the magnetic ring portion (first portion) of the magnetic attraction component 42 and the edge of the housing 12 is less than or equal to 2 mm. This design is to avoid interference between the housing 12 of the mobile power supply 10 and the mobile phone camera.

[0032] Preferably, a soft rubber pad 52 is also attached to the charging surface 44, and the soft rubber pad 52 can increase the friction of the mobile phone against it to prevent the mobile phone from falling. The soft rubber pad 52 is connected to the charging surface 44, for example, by gluing. In the illustrated embodiment, the soft rubber pad 52 is provided with an avoidance position 54 for avoiding the part of the first accommodating portion 48 protruding from the charging surface 44. The avoidance position 54 is, for example, a through hole, and the area in the through hole corresponding to the wireless charging coil 38 is filled with a decorative piece 56. The decorative piece 56 is, for example, made of soft rubber material, which can play a decorative role and avoid the unevenness of the surface connected to the mobile phone. Optionally, the outer surface of the protruding part of the first accommodating portion 48, the outer surface of the soft rubber pad 52, and the outer surface of the decorative piece 56 are arranged flush.

[0033] The transformer 40 is electrically connected to the side of the circuit board 36 facing the bottom plate 24. A heat sink 58 is provided between the circuit board 36 and the bottom plate 24. The heat sink 58 is, for example, a sheet-like structure. Specifically, the heat sink 58 is located between the transformer 40 and the inner wall of the bottom plate 24. The heating surface of the transformer 40 contacts the side of the heat sink 58 facing away from the bottom plate 24. The side of the heat sink 58 facing away from the transformer 40 contacts the inner wall of the bottom plate 24, so that the heat generated by the transformer 40 is conducted to the heat sink 58, and the heat sink 58 spreads the heat and dissipates it to the outside through the bottom plate 24.

[0034] In the illustrated embodiment, a button 60 and a data interface 62 are provided at one end of the side of the housing 12 in the length direction close to the circuit board 36, and the button 60 and the data interface 62 are electrically connected to the circuit board 36, respectively, wherein the button 60 can be used to control the opening or closing of the mobile power supply 10, and to adjust the charging parameters, and the data interface 62 can be connected to an external power supply to charge the power supply 34, or the data interface 62 can be connected to an electronic device such as a mobile phone through a data cable to charge it by wire, so that the mobile power supply 10 has both wireless charging and wired charging functions. Preferably, a display light 64 is provided at a position corresponding to the circuit board 36 on the cover plate 20, and the display light 64 is electrically connected to the circuit board 36, and is used to indicate the charging status and display the power level of the power supply 34.

[0035] like Figure 6 As shown, the bracket 14 is arranged on the side of the cover plate 20 away from the installation space 32, and the setting position of the bracket 14 corresponds to the area where the power supply 34 is located. Specifically, the bracket 14 also includes a base 66, and the support member 16 is rotatably connected to the base 66 through a rotating assembly 68. The base 66 is rotatably connected to the cover plate 20, so that the support member 16 can provide 360-degree multi-angle and multi-form support. In this embodiment, the support member 16 and the base 66 are both annular, and a storage portion 70 is provided on the side of the cover plate 20 away from the installation space 32. The storage portion 70 is, for example, an annular groove structure, and the base 66 is rotatably arranged in the storage portion 70. For example, the central axis of the storage portion 70 perpendicular to the direction of the cover plate 20 coincides with the central axis of the base 66 perpendicular to the direction of the cover plate 20, and the base 66 rotates around the central axis as the rotation axis.

[0036] Preferably, a protrusion 72 is provided on the radial outer side wall of the base 66, and a recess 74 is correspondingly provided on the inner side wall of the receiving portion 70. When installed, the protrusion 72 protrudes into the recess 74, and the two form a limiting structure to axially limit the base 66 to prevent the base 66 from escaping from the receiving portion 70. In other embodiments, the positions of the protrusion 72 and the recess 74 can be interchanged, or other limiting structures can be used to limit the base 66.

[0037] Furthermore, a damping member 76 is provided between the base 66 and the receiving portion 70. The damping member 76 can increase the resistance to the rotation of the base 66 and can also separate the base 66 from the cover plate 20 to prevent the base 66 from scratching against the inner wall of the receiving portion 70 during the rotation process to produce a harsh sound. In the illustrated embodiment, a groove 78 is provided on one side of the base 66 close to the installation space 32. The damping member 76 is fixed to the bottom wall of the receiving portion 70 by, for example, gluing, and the base 66 is supported on the damping member 76 by the groove 78 being engaged with the top portion of the damping member 76.

[0038] Please also refer to Figure 7As shown, a placement position 67 is provided on the side of the base 66 away from the installation space 32. The placement position 67 is, for example, a groove structure that runs through the inner side wall of the base 66, that is, the side wall of the placement position 67 has a certain thickness, which increases the structural strength of the base 66 and prevents the support member 16 from breaking during the rotation or support process. When the support member 16 is in the storage state, the support member 16 is stored in the placement position 67. Specifically, the rotating assembly 68 is located in the middle area of ​​the cover plate 20, and the rotating assembly 68 is connected to the side parts of the support member 16 and the base 66. The rotating assembly 68 includes a first connecting member 80, a second connecting member 82 and a rotating shaft 84. One end of the first connecting member 80 is fixedly connected to the support member 16, and the other end is rotatably matched with the rotating shaft 84. One end of the second connecting member 82 is fixedly connected to the base 66, and the other end is rotatably matched with the rotating shaft 84.

[0039] More specifically, the first connecting member 80 includes a first connecting portion 86 and a shaft sleeve 88 connected to one end of the first connecting portion 86, and the second connecting member 82 includes a second connecting portion 90 and a pivot seat 92 connected to one end of the second connecting portion 90. For example, two pivot seats 92 are provided, and the two pivot seats 92 are arranged at intervals, and each pivot seat 92 is provided with an axis hole 94. A first connecting position 96 is provided at the outer edge of the support member 16 facing the installation space 32. The first connecting position 96 is, for example, a groove structure. The first connecting portion 86 is fixedly connected to the first connecting position 96. For example, a rivet column is provided in the first connecting position 96, and a rivet hole is provided on the first connecting portion 86. The first connecting portion 86 is fixedly connected to the first connecting position 96 through the rivet column and the rivet hole, and the shaft sleeve 88 protrudes out of the first connecting position 96. Similarly, the base 66 is provided with a second connection position 98 at the outer edge of the side facing the installation space 32, and the second connection position 98 includes a groove structure and an opening structure. The second connection part 90 is fixedly connected to the groove structure of the second connection position 98, for example, a riveting column is provided in the groove structure of the second connection position 98, and a riveting hole is provided on the second connection part 90. The second connection part 90 is riveted and fixed to the groove structure of the second connection position 98 through the riveting column and the riveting hole, and the pivot seat 92 protrudes out of the groove structure of the second connection position 98 and is penetrated in the opening structure, so that the shaft hole 94 corresponds to the sleeve hole position of the shaft sleeve 88. The shaft sleeve 88 is located between the two pivot seats 92, and the rotating shaft 84 is penetrated in the shaft hole 94 and the shaft sleeve 88, thereby realizing the rotatable connection between the support member 16 and the base 66. Preferably, a damping structure can be arranged between the rotating shaft 84 and the sleeve 88 or the shaft hole 94 to increase the rotational resistance of the support member 16; alternatively, the side surface of the rotating shaft 84 can be arranged to be a plane and an arc surface connected in sequence, such as two opposite planes and two opposite arc surfaces, and the sleeve 88 or the shaft hole 94 is designed to be compatible with the side structure of the rotating shaft 84, and the sleeve 88 is, for example, a flexible metal, thereby forming rotational resistance during rotation.

[0040] Preferably, if Figure 6 and Figure 7 As shown, a reinforcing portion 102 is convexly provided at the rotation connection on one side of the base 66 close to the support member 16. The reinforcing portion 102 is, for example, a convex block structure, which is used to increase the structural strength of the rotation connection part of the base 66 to prevent the support member 16 from breaking during the rotation or support process. Specifically, the reinforcing portion 102 is arranged near the second connection position 98. Two reinforcing portions 102 can be arranged. The two reinforcing portions 102 are located at opposite ends of the second connection position 98, and the reinforcing portions 102 are located in the placement position 67. For example, the reinforcing portion 102 is formed by extending from the side wall of the placement position 67 to the placement position 67. Correspondingly, the first connection portion 86 is provided with avoidance portions 104 corresponding to the two reinforcing portions 102. The avoidance portions 104 are, for example, a groove structure. The avoidance portions 104 are used to avoid the reinforcing portion 102 when the support member 16 rotates to the storage state, that is, when the support member 16 rotates to the storage state, the reinforcing portion 102 is stored in the corresponding avoidance portion 104 to avoid interference.

[0041] It should be understood that in other embodiments, the rotating assembly 68 may also be designed as other rotating structures. The present application does not limit the specific implementation structure of the rotating assembly 68, as long as the support member 16 and the base 66 can be rotatably connected.

[0042] In the illustrated embodiment, a hand-locking position 100 is provided on a side of the support member 16 opposite to the rotating assembly 68 . The hand-locking position 100 is, for example, a notch, which facilitates the user to operate the support member 16 to rotate.

[0043] Preferably, the bracket 14 is disposed adjacent to the power source 34 and can be made of metal material to improve support stability and to conduct heat generated by the mobile power source 10 , such as heat generated by the power source 34 , thereby improving heat dissipation effects.

[0044] Preferably, the bracket 14 is arranged near one end of the housing 12, for example, the bracket 14 is arranged near the top of the housing 12, that is, the end away from the display light 64. The purpose of such arrangement is to make the bracket 14 correspond to the magnetic suction component 42, and when the mobile power supply 10 is adsorbed on the back of the mobile phone, the bracket 14 is close to the middle of the mobile phone, which can provide better support function.
