Referring to fig. 16 and 17, in use, the first housing 10 is held, the second housing 20 is rotated, the mounting seat 52 and the push-pull rod 151 are rotated due to the arrangement of the screw threads, and the guide members 222, such as the first guide 2221 and the second guide 2223, are engaged with the mounting seat 52, so that the mounting seat 52 moves in the axial direction of the push-pull rod 151, and the mounting seat 52 drives the first plug 511 and the second plug 512 to extend out of the second accommodating cavity 23 or retract into the second accommodating cavity 23 through the change of the rotation direction of the second housing 20.

Referring to fig. 24 and fig. 25, which respectively disclose cross-sectional views of the power adapter 100 shown in fig. 3, when the first pin 511 and the second pin 512 are at least partially located outside the second accommodating cavity 23, the abutting member 323 abuts against the first pin 511, the abutting member 323 abuts against the second pin 512, and when the first pin 511 and the second pin 512 are retracted into the second accommodating cavity 23, the mounting seat 52 drives the first pin 511 and the second pin 512 to move toward the first housing 10, so that the abutting member 323 is disconnected from the first pin 511, and the abutting member 323 is disconnected from the second pin 512.

The ejection member 15, for example, the push-pull rod 151 pushes the second connector 50, for example, the mount 52, in response to the rotation of the first housing 10 relative to the second housing 20, so that the second connector 50, for example, the first pins 511 and the second pins 512, slide in the extending direction of the slide ways 521 to protrude out of the second accommodating cavity 23, and when the second connector 50, for example, the first pins 511 and the second pins 512, protrude out of the second accommodating cavity 23, the first pins 511 are brought into abutment with the abutment 323 of the electronic component 30, for example, the first conductive member 32a, and the second pins 512 are brought into abutment with the abutment 323 of the electronic component 30, for example, the second conductive member 32 b.

The ejection member 15, for example, the push-pull rod 151, pulls the second connector 50, for example, the mount 52, in response to the rotation of the first housing 10 relative to the second housing 20, so that the second connector 50, for example, the first prong 511 and the second prong 512, slide along the extending direction of the slide 521 to retract to the second accommodating cavity 23, and when the second connector 50, for example, the first prong 511 and the second prong 512, retract to the second accommodating cavity 23, the disconnection of the first prong 511 from the abutment 323 of the electronic component 30, for example, the first conductive member 32a, and the disconnection of the second prong 512 from the abutment 323 of the electronic component 30, for example, the second conductive member 32b, are achieved.

Referring to fig. 1, when the first housing 10 and the second housing 20 rotate relatively, the outer surface of the first housing 10 and the outer surface of the second housing 20 are always flush, that is, there is no corner between the contact portions of the first housing 10 and the second housing 20, so that the appearance performance is improved. Therefore, there is no limitation on the rotation angle of the first housing 10 and the second housing 20 for rotating relative to each other to rotate or retract the second connector 50.

In an embodiment, the first housing 10 can rotate by 360 ° relative to the second housing 20, so that the second connector 50 can move from a state of being completely accommodated in the second accommodating cavity 23 to a state of being maximally extended out of the second accommodating cavity 23. Of course, the rotation angle may be 45 ° or 90 °. The rotation angle can be set according to actual needs, and is not described in detail.

Referring to fig. 26, a schematic structural diagram of another variation of the power adapter 100 of fig. 1 is disclosed. The first casing 10 and the second casing 20 of the power adapter 100 are both of a cylindrical structure with a square cross section. Of course, the first casing 10 and the second casing 20 may be both of a columnar structure having a polygonal cross section. Therefore, when the first casing 10 and the second casing 20 are relatively rotated, an edge angle is generated between the portions where the first casing 10 and the second casing 20 are in contact with each other, and the appearance performance is affected. When the second connector 50 is completely accommodated in the second accommodating chamber 23, an edge is formed between the portions of the first housing 10 and the second housing 20 that contact each other, which may affect the accommodation. When the second connector 50 is moved to a state of maximally protruding out of the second receiving chamber 23. The use is affected by the corner angle generated between the contact portions of the first casing 10 and the second casing 20.

Therefore, it is necessary to limit the rotation angle of the first housing 10 and the second housing 20 for rotating relative to each other to rotate the second connector 50 out of or into the housing, so that when the housing and the use are both in the two states, the outer surface of the first housing 10 and the outer surface of the second housing 20 are flush, and there is no corner between the contact portions of the first housing 10 and the second housing 20, thereby improving the appearance of the power adapter 100. For example, the rotation angle may be an integer multiple of 90 °.

Referring to fig. 26, a first accommodating groove 123 is disposed on a side of the first side plate 12 of the first casing 10 facing the second casing 20. The first magnetic member 124 is disposed in the first receiving groove 123. The second housing 20 has a second receiving groove 224 formed on a side of the second side plate 22 facing the first housing 10. The second magnetic member 225 is disposed in the second receiving groove 224. The first magnetic member 124 and the second magnetic member 225 are configured to attract each other with opposite polarities. The first housing 10 can be rotated by an integral multiple of 360 ° relative to the second housing 20, and the second connector 50 can be moved from the state of being completely accommodated in the second accommodating chamber 23 to the state of being maximally extended out of the second accommodating chamber 23.

When the second connector 50 is completely accommodated in the second accommodating cavity 13, the first magnetic member 124 and the second magnetic member 225 are opposite and attracted, so that a user can easily perceive that the first housing 10 and the second housing 20 rotate to the right position, the outer surface of the first housing 10 is flush with the outer surface of the second housing 20, and the contact part between the first housing 10 and the second housing 20 has no corner angle, so that the housing is convenient.

When the second connector 50 is moved to a state of maximally protruding out of the second receiving chamber 23. The first magnetic member 124 and the second magnetic member 225 are opposite and attracted to each other, so that a user can easily perceive that the first casing 10 and the second casing 20 are relatively rotated to the proper position, meanwhile, the outer surface of the first casing 10 is flush with the outer surface of the second casing 20, and the mutual contact position between the first casing 10 and the second casing 20 has no corner angle, thereby being convenient for use.

It is understood that the number of the first magnetic member 124 and the second magnetic member 225 may be plural. The first and second

magnetic members

124 and 225 may be circumferentially evenly distributed about an axis of rotation of the first housing 10 relative to the second housing 20. For example, the number of the first magnetic members 124 may be two, and when the second magnetic member 225 is opposite to and attracted to any one of the two first magnetic members 124, the outer surface of the first casing 10 is flush with the outer surface of the second casing 20, and there is no corner between the contact portions of the first casing 10 and the second casing 20. When the second magnetic member 225 is opposite to and attracted to one of the two first magnetic members 124, the second connector 50 is in a state of being completely accommodated in the second accommodating cavity 23. When the second magnetic member 225 is directly attracted to the other of the two first magnetic members 124, the second connector 50 is in a state of being moved to be maximally protruded out of the second receiving chamber 23.

It can be understood that, the first magnetic member 124 and the second magnetic member 225 can both be magnets, and the arrangement of the first magnetic member 124 and the second magnetic member 225 can produce in-place centering effect, thereby avoiding poor appearance and improving user experience. Also in embodiments where a battery is present, both the first magnetic member 124 and the second magnetic member may be electromagnets.

The design that the first shell 10 and the second shell 20 rotate concentrically relative to each other is adopted, and the ejection mechanism 60 is adjusted through the relative rotation of the first shell 10 and the second shell 20, so that the second connector 50 is displaced, at least part of the second connector 50 is located outside the accommodating cavity 101 for normal use, and the second connector 50 is located in the accommodating cavity 101 for accommodating. This application technical scheme is simple, and is reliable, realizes unscrewing of power adapter, locking and collection, reduces the product size, prevents the maloperation, promotes user experience.
