[0035] The specific number of the pins 16 is not limited, for example, two or three, and in the present application, the number of the pins 16 is two, and the two pins 16 are arranged in parallel at intervals.

[0036] The specific connection mode between the mounting fitting 18 and the charging body 12 is not limited, for example, mechanical fixed connection, buckle connection, glue connection and the like.

[0037] The corner of the shell 20 is provided with a mounting position 24, the shape of the mounting position 24 is matched with the shape of the mounting fitting 18, and the mounting fitting 18 is mounted on the mounting position 24 to enhance the compactness between the shell 20 and the mounting fitting 18 and reduce the sense of strangeness of the mounting fitting 18.

[0038] It can be understood that the mounting position 24 can be a mounting groove recessed on the outer side of the shell 20, the mounting groove being recessed from the outer surface of the shell to the inner surface and being spaced apart from the inner surface by a certain distance, or the mounting position 24 can also be a notch penetrating through the shell 20, the notch communicating the interior of the shell 20 with the external space.

[0039] In an embodiment, the mounting position 24 is a notch provided on the shell 20, the notch penetrating through the shell 20 so as to increase the depth of the mounting position 24 and facilitate the accommodation of the mounting accessory 18. Preferably, the profile shape of the notch is adapted to the profile shape of the mounting accessory 18, and after the mounting accessory 18 is mounted to the notch, the outer surface of the mounting accessory 18 is flush with the outer surface of the shell 20, that is, the mounting accessory 18 does not protrude outwardly from the shell 20, further reducing the conspicuousness of the mounting accessory 18.

[0072] In an embodiment, pin assembly 14 further comprises conductive piece 58 clamped between seat 48 and cover 50, one end of conductive piece 58 is located between seat 48 and cover 50 and electrically connected with pin 16, the other end of conductive piece 58 is located outside mounting seat 46 and electrically connected with charging body 12, i.e. charging assembly 22, so that pin 16 is electrically connected with charging assembly 22.

[0073] In this embodiment, conductive piece 58 is a metal spring piece, so that conductive piece 58 not only has the effect of conducting electricity, but also has a certain elasticity.

[0074] Avoidance hole 60 is provided through conductive piece 58, avoidance hole 60 corresponds to positioning post 52, when conductive piece 58 is clamped between seat 48 and cover 50, positioning post 52 passes through avoidance hole 60 and is inserted into positioning hole 54, thereby forming a positioning effect on conductive piece 58 and enhancing the stability of conductive piece 58.

[0075] Conductive piece 58 comprises clamping part 62 and elastic connecting part 64, clamping part 62 is clamped between seat 48 and cover 50, elastic connecting part 64 is connected to one end of clamping part 62 and electrically connected with pin 16, and the end of conductive piece 58 electrically connected with charging body 12 is connected to the end of clamping part 62 away from elastic connecting part 64.

[0076] The elastic connecting portion 64 is arranged obliquely relative to the clamping portion 62, that is, an angle is formed between the elastic connecting portion 64 and the clamping portion 62, and the elastic connecting portion 64 extends obliquely from the clamping portion 62 towards the first wall portion 32. The elastic connecting portion 64 has a certain elasticity. During the rotation of the pin 16 relative to the first wall portion 32, the pin 16 will press the elastic connecting portion 64, so that the elastic connecting portion 64 is elastically deformed, thereby forming an elastic force. Under the action of the elastic force, the elastic connecting portion 64 is pressed against the pin 16, so that the pin 16 always maintains contact with the conductive part 58 during the rotation, thereby forming an electrical connection effect.

[0077] Specifically, when the pin 16 is received in the receiving groove 26, one end of the pin 16 abuts against one end of the elastic connecting portion 64 away from the clamping portion 62. When the pin 16 is turned out of the receiving groove 26, the end of the pin 16 abutting against the elastic connecting portion 64 moves along the extension direction of the elastic connecting portion 64 towards the clamping portion 62 and presses the elastic connecting portion 64.

[0078] The side of the elastic connecting portion 64 facing the pin 16 is provided with a groove 66, and one end of the pin 16 is provided with a protrusion 68 cooperating with the groove 66. The protrusion 68 is movably inserted into the groove 66. When the pin 16 rotates relative to the first wall portion 32, the protrusion 68 slides in the groove 66, thereby playing a certain guiding effect and preventing the pin 16 from separating from the elastic connecting portion 64.

[0079] In an embodiment, the charging body 12 is provided with a hanging rope 70. The inner side of the hanging rope 70 forms a hand holding space, so that the user can hold or hang the charging device 10 on the hand through the hanging rope 70, without the need to hold it in the hand.

[0080] The above embodiment is only a preferred embodiment of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
