Abstract
Claims
1. A charging plug, characterized in that, The device includes a housing, a linkage assembly, and multiple pins. The multiple pins include a ground pin and a pair of power pins. The ground pin and the pair of power pins are rotatably disposed on the housing and have an extended state that partially extends out of the housing and a retracted state that is retracted into the housing. The linkage assembly includes a meshing gear and a rack. Each power pin is coaxially fixed with one of the gears. The rack is slidably disposed in the housing and is drivenly connected to the ground pin to drive the ground pin and the pair of power pins to fold or unfold synchronously.
2. The charging plug of claim 1, wherein, The housing includes a bottom shell and a cover plate disposed on the bottom shell. The inner surface of the bottom shell is provided with a first mounting seat, a second mounting seat, and a third mounting seat. The second mounting seat is located between the first mounting seat and the third mounting seat. Each of the pins includes a connected rotating part and a plugging part. The rotating part of the grounding pin is rotatably disposed on the second mounting seat. The rotating parts of a pair of power pins are respectively rotatably disposed on the first mounting seat and the third mounting seat, and are coaxially fixedly connected to the corresponding gear. The rack is slidably disposed on the second mounting seat.
3. The charging plug of claim 2, wherein, A first receiving groove is provided between the first mounting base and the second mounting base, and a second receiving groove is provided between the third mounting base and the second mounting base. The two gears are respectively provided in the first receiving groove and the second receiving groove.
4. The charging plug of claim 2, wherein, The linkage component includes a linkage pin, the rotating part of the grounding electrode pin has a rotation axis, the rotation axis is parallel to the central axis of the linkage pin, the linkage pin passes through the rotating part of the grounding electrode pin, and there is a driving gap between the central axis of the linkage pin and the rotation axis, and the rack is connected to the linkage pin in a transmission manner.
5. The charging plug of claim 4, wherein, Viewed along the axial direction of the linkage pin, the rotating part of the grounding electrode pin includes a first part located away from the cover plate along the rotation axis and a second part located close to the cover plate along the rotation axis. The linkage pin passes through the first part. The rack is located on the side of the gear close to the cover plate and is provided with a drive groove that extends through the rack in a direction parallel to the rotation axis. The drive groove extends in a direction away from the cover plate. The linkage pin passes through the drive groove and abuts against the inner wall of the drive groove.
6. The charging plug of claim 2, wherein, The rack has a limiting groove on the side away from the cover plate, and the second mounting seat engages with the limiting groove of the rack.
7. The charging plug of claim 2, wherein, The first mounting base is provided with a spring piece, which includes a fixed part and a pressing part connected together. The fixed part is fixedly connected to the first mounting base. The outer peripheral surface of the rotating part of the grounding electrode pin is provided with a positioning boss, and the pressing part presses against the positioning boss.
8. The charging plug of claim 7, wherein, The positioning boss has a first positioning side and a second positioning side that are opposite to each other. When the grounding electrode pin is in the extended state, the clamping part is pressed against the first positioning side. When the grounding electrode pin is in the retracted state, the clamping part is pressed against the second positioning side.
9. The charging plug of claim 1, wherein, The gear is a sector gear.
10. The charging plug of claim 2, wherein, The bottom shell is provided with a ground pole accommodating groove for accommodating the ground pole pin, and an inner recessed pushing groove is arranged on the outer peripheral surface of the bottom shell, and the pushing groove is communicated with the ground pole accommodating groove. When the ground pole pin is in the accommodating state, the ground pole pin is accommodated in the ground pole accommodating groove and partially extends into the pushing groove.
