[0021] The embodiment of the present invention provides a charger, comprising a charger body 1, a cover and an opening and closing mechanism, wherein the cover comprises a first cover 2 and a second cover 3; a plug 15 is provided at the top end of the charger body 1, and the first cover 2 and the second cover 3 are rotatably connected to the top end of the charger body 1 around a preset axis; by applying a torque to any one of the first cover 2 and the second cover 3, the first cover 2 and the second cover 3 can be rotated in opposite directions with the help of the opening and closing mechanism, so that the cover can be switched between an open state and a closed state; When the cover is in a closed state, the side of the first cover 2 away from the preset axis and the side of the second cover 3 away from the preset axis are butted against each other, and the plug 15 is accommodated in the cover; When the cover is in an open state, a side of the first cover 2 away from the preset axis and a side of the second cover 3 away from the preset axis are spaced apart from each other so that the plug 15 is exposed from the first cover 2 and the second cover 3 .

[0022] In this embodiment, the first cover 2 and the second cover 3 are installed on the top of the charger plug 15, and the first cover 2 and the second cover 3 are rotated in opposite directions around a preset axis through an opening and closing mechanism, for example, the first cover 2 rotates counterclockwise and the second cover 3 rotates clockwise. When charging is not needed, the first cover 2 and the second cover 3 are combined into one to form a cover, and the plug 15 is built into the receiving groove in the first cover 2 and the second cover 3. At this time, the plug 15 is not exposed to the outside. When charging is needed, one of the first cover 2 and the second cover 3 is manually rotated, and the other direction is rotated to expose the plug 15 to the outside, and then the plug 15 is inserted into the socket. The plug 15 is selectively hidden by the cover, thereby preventing the plug 15 from being exposed all the time, thereby reducing the phenomenon of the plug 15 scratching other objects.

[0023] The charger body 1 has a top end surface and a bottom end surface that are oppositely disposed, and the plug 15 passes through the top end surface; When the cover is in an open state, the side of the first cover 2 away from the preset axis is flush with or lower than the top surface, and the side of the second cover 3 away from the preset axis is flush with or lower than the top surface.

[0024] In this embodiment, the first cover 2 and the second cover 3 both rotate around a preset axis. In this embodiment, when the covers are in the open state, the first cover 2 and the second cover 3 are flush with the top end surface of the charger body 1, and the part where the plug 15 passes through the charger body 1 completely exposes the first cover 2, the second cover 3 and the charger, so that the user can insert the plug 15 into the socket.

[0025] As an example, at least one of the first cover 2 and the second cover 3 is provided with a receiving groove; When the cover is in a closed state, the plug 15 is embedded in the receiving groove; when the cover is in an open state, the plug 15 is separated from the receiving groove. In this embodiment, both the first cover 2 and the second cover 3 are provided with receiving grooves. When the cover is in a closed state, the plug 15 is located at the intersection of the receiving groove of the first cover 2 and the receiving groove of the second cover 3.

[0026] As an example, the opening and closing mechanism includes a planetary carrier 44, a sun gear 41, a ring gear 43 and multiple planetary gears 42, and the sun gear 41 and the multiple planetary gears 42 are arranged in the ring gear 43; the sun gear 41 rotates around a preset axis to connect to the charger body 1, and the sun gear 41 is connected to the first cover 2 so that the first cover 2 rotates with the sun gear 41.

[0027] The ring gear 43 is connected to the second cover 3, the ring gear 43 rotates around the preset axis, and the ring gear 43 and the sun gear 41 are coaxial; The planetary gears 42 rotate around their own axes. The planetary gears 42 are respectively meshed between the sun gear 41 and the ring gear 43 . A plurality of planetary gears 42 are evenly distributed around the sun gear 41 .

[0028] The planetary carrier 44 includes a baffle 441, a first rotating shaft 442 and multiple second rotating shafts 443, one end of the first rotating shaft 442 is fixed to the charger body 1, and the other end of the first rotating shaft 442 is fixed to the baffle 441, the sun gear 41 is sleeved on the first rotating shaft 442 so as to be able to rotate on the first rotating shaft 442, the second rotating shaft 443 is fixed to the baffle 441, each of the planetary gears 42 is arranged on the second rotating shaft 443 so as to be able to rotate on the second rotating shaft 443, and the planetary gears 42, the sun gear 41 and the ring gear 43 are arranged between the baffle 441 and the charger body 1.

[0029] The planet carrier 44 in this embodiment is used to provide a rotating shaft 4432 for the sun gear 41 and the planet gear 42, and also stabilizes the position of the ring gear 43, the sun gear 41 and the planet gear 42 to avoid displacement of the position of any one or more of the planet gear 42, the sun gear 41 and the ring gear 43 during rotation.

[0030] In this embodiment, the rotation direction of the ring gear 43 is opposite to that of the sun gear 41, and the planetary gear 42 rotates around its own axis in situ. When the user opens one of the first cover 2 and the second cover 3, the other of the first cover 2 and the second cover 3 will rotate in the opposite direction driven by the opening and closing structure, so that the cover begins to move toward the open state.

[0031] The sun gear 41 is connected to the first cover 2, and the ring gear 43 is connected to the second cover 3; by applying a torque to the first cover 2, the sun gear 41 can be driven to rotate, and then the second cover 3 is driven to rotate in the opposite direction of the first cover 2 through the planetary gear 42 and the ring gear 43; by applying a torque to the second cover 3, the ring gear can be driven to rotate, and then the first cover 2 is driven to rotate in the opposite direction of the second cover 3 through the planetary gear 42 and the sun gear 41.

[0032] As an example, three of the planetary gears 42 and the second rotating shafts 443 are respectively provided, and the three second rotating shafts 443 are evenly distributed around the preset axis and the axes of the three second rotating shafts 443 are respectively spaced apart from the preset axis. The three second rotating shafts 443 are divided into a limiting rotating shaft 4431 and two rotating shafts 4432, the length of the limiting rotating shaft 4431 is greater than the rotating shaft 4432, one end of the limiting rotating shaft 4431 is fixed to the charger body 1, and the other end of the limiting rotating shaft 4431 is fixed to the blocking piece 441. An arc groove 23 is provided on the first cover 2, and the middle part of the limiting rotating shaft 4431 is penetrated through the arc groove 23, so that the rotation angle of the first cover 2 is limited. The arc groove 23 is an arc-shaped groove, and the center of the arc groove 23 coincides with a point of the preset axis.

[0033] In this embodiment, the curvature of the arc groove 23 is the rotation angle of the first cover 2, and is also half of the angle between the first cover 2 and the second cover 3 when the cover is in the open state.

[0034] As an example, the charger body 1 includes a shell, and the shell includes a first shell 11 and a second shell 12. The first shell 11 and the second shell 12 are in the shape of a rectangular parallelepiped, the volume of the first shell 11 is smaller than the volume of the second shell 12, one end of the first shell 11 constitutes the top of the charger body 1, and the plug is arranged on the first shell 11. In this embodiment, the charger body 1 is divided into a first shell 11 and a second shell 12 in the top and bottom directions, and the first shell 11 and the second shell 12 make the front view of the charger body 1 roughly convex. In fact, the shell is assembled from a first part 13 and a second part 14, and an inner cavity is arranged on the first part 13, and the inner cavity has an opening, and the second part 14 closes the opening and is connected to the first part 13.

Taking the example that the first connection end 21 and the first rotation end 31 are connected by an opening and closing mechanism, and the second connection end 22 and the second rotation end 32 are connected to the charger body 1 by pivoting, only a single opening and closing mechanism is used, and the dependence on the opening and closing mechanism is high. Due to problems such as processing accuracy and incomplete gear meshing, the rotation angle of the side using the opening and closing mechanism may not be completely synchronized with the side not using the opening and closing mechanism, and an unbalanced condition is likely to occur during the rotation process. However, this embodiment uses an opening and closing mechanism on each of the opposite sides of the charger, which can maximize the synchronous movement of the two opening and closing mechanisms during use, so that the cover can rotate more balanced and more synchronously on the opposite sides of the charger body 11.

In this embodiment, the arc grooves 23 in the first blind hole 24 and the second blind hole are symmetrical, and the axes of the limiting rotating shafts 4431 in the two opening and closing mechanisms are overlapped, so that the two opening and closing mechanisms rotate at the same angle, and the rotation starting point and the rotation end point are the same.
