[0038] Referring to Figure 1 , the rotating shaft structure comprises a first rotating body 1, a second rotating body 2, and a rotating shaft 3. The rotating shaft 3 is arranged through the first rotating body 1 and the second rotating body 2. The first rotating body 1 is configured to connect the box body, and the second rotating body 2 is configured to connect the cover body. The second rotating body 2 can rotate relative to the first rotating body 1 around the rotating shaft 3 to realize the opening and closing of the cover body and the box body.

[0039] In this embodiment, the shape of the first rotating body 1 and the second rotating body 2 after assembly can be part of a spherical shape or a spherical shape, which can be suitable for a charging box with a circular arc rotating position, while a hinge or a linear rotating shaft cannot be suitable for such a charging box.

[0040] Referring to Figure 2 , the first rotating body 1 comprises a first rotating arm 11 and a first rotating disc 12. The first rotating arm 11 is provided with a first connecting portion 1112, and the first connecting portion 1112 is connected with the box body.

The side of the first rotating disc 12 facing the second rotating body 2 is provided with a first tooth portion 121. The second rotating body 2 is configured to connect the cover body, and the side of the second rotating body 2 facing the first rotating disc 12 is provided with a second tooth portion 221. The second tooth portion 221 can be engaged with the first tooth portion 121 to limit the first rotating body 1 and the second rotating body 2.

[0041] The driving mechanism 4 is at least partially arranged in the first inner cavity 110 of the first rotating arm 11. Referring to Figure 6The driving mechanism 4 comprises a driving member 41 and an elastic member 42. The driving member 41 is connected with the first rotating disc 12, and the two ends of the elastic member 42 are connected with the driving member 41 and the first rotating arm 11 respectively. When it is needed to open the cover body, an external force is applied to the driving member 41, so that the driving member 41 moves along the radial direction of the first rotating arm 11 and compresses the elastic member 42, the driving member 41 drives the first rotating disc 12 to move along the axial direction of the first rotating arm 11 and away from the second rotating body 2, so that the first tooth portion 121 is separated from the second tooth portion 221, at this time, the second rotating body 2 can rotate relative to the first rotating body 1 around the rotating shaft 3, so that the cover body can be opened relative to the box body; after the cover body is opened, the elastic member 42 rebounds to drive the driving member 41 to reset, the driving member 41 drives the first rotating disc 12 to be close to the second rotating body 2, and the first tooth portion 121 is engaged with the second tooth portion 221, so that the position relationship between the second rotating body 2 and the first rotating body 1 is fixed; when it is needed to close the cover body, an external force is applied to the driving member 41 again, so that the first rotating disc 12 and the second rotating body 2 are away from each other, the first tooth portion 121 is separated from the second tooth portion 221, and the cover body can be closed relative to the box body; after the cover body is closed, the elastic member 42 rebounds to drive the driving member 41 to reset, and the first tooth portion 121 is engaged with the second tooth portion 221, so that the first rotating body 1 and the second rotating body 2 are limited. Optionally, the elastic member 42 is a spring.

[0042] The first rotating arm 11 is in a disc shape. Referring to Figure 8 The first rotating arm 11 comprises a rotating arm body 111 and a cover plate 112 connected with the rotating arm body 111, and the rotating arm body 111 and the cover plate 112 jointly enclose the first inner cavity 110, wherein the first connecting portion 1112 extends outward from the outer circumferential side of the rotating arm body 111. By separately arranging the rotating arm body 111 and the cover plate 112, the first rotating disc 12 and the driving mechanism 4 can be assembled in the first inner cavity 110.

[0043] The first rotating disc 12 is in a disc shape. Referring to Figure 7 The first rotating disc 12 is provided with a first shaft hole 122 for the rotating shaft 3 to pass through, and the first shaft hole 122 is located in the central region of the first rotating disc 12.

[0044] Referring to Figure 7 The first rotating disc 12 is provided with a guide groove 120, which is recessed inward from the first disc surface of the first rotating disc 12, the first disc surface is an inclined surface inclined relative to the radial cross section of the first rotating disc 12, and the first tooth portion 121 protrudes outward from the second disc surface of the first rotating disc 12.

[0045] Specifically, referring to Figure 10The guide groove 120 comprises a groove bottom wall 1201 and a groove side wall 1202, the groove side wall 1202 is connected with the groove bottom wall 1201, the groove bottom wall 1201 is inclined relative to the radial section of the first rotating arm 11, the driving member 41 is at least partially arranged in the guide groove 120 and can move in the guide groove 120, the side of the driving member 41 extending into the guide groove 120 is matched with the groove bottom wall 1201 and the groove side wall 1202, since the first side 4111 of the driving member 41 is matched with the groove bottom wall 1201, the first side 4111 of the driving member 41 is an inclined surface relative to the radial section of the first rotating arm 11. Through the inclined matching between the first side 4111 of the driving member 41 and the groove bottom wall 1201, the first rotating disc 12 can be subjected to the force in the axial direction during the movement of the driving member 41 in the radial direction of the first rotating arm 11. In the utility model, the movement direction of the driving member 41 and the movement direction of the first rotating disc 12 are in different directions, so that the installation position of the driving member 41 is convenient to set.

[0046] In the embodiment, the length direction of the driving member 41 is perpendicular to the axial direction of the rotating shaft 3, the movement direction of the driving member 41 is perpendicular to the axial direction of the rotating shaft 3, since the first rotating disc 12 moves along the length direction of the rotating shaft 3, that is, the movement direction of the driving member 41 is also perpendicular to the movement direction of the first rotating disc 12.

[0047] Based on the inward movement of the first rotating disc 12 by pressing the driving member 41, the width of the driving member 41 gradually increases from the pressing end to the supporting end along the axial direction of the rotating shaft 3, it needs to be explained that the inward movement of the first rotating disc 12 means that the first rotating disc 12 moves away from the second rotating body 2, and the supporting end means one end connected with the elastic member 42.

[0048] During the pressing of the driving member 41, in order to prevent the separation of the driving member 41 and the first rotating disc 12, that is, in order to make the driving member 41 drive the inward movement of the first rotating disc 12, referring to Figure 10 Along the first direction, the width of the groove bottom wall 1201 is greater than the width of the slot opening 1200 of the guide groove 120, so that the driving member 41 and the first rotating disc 12 can be axially limited, wherein the first direction is perpendicular to the axial direction of the rotating shaft 3 and also perpendicular to the length direction of the driving member 41.

[0049] In some embodiments, the guide groove 120 is a dovetail groove, referring to Figure 10The slot side wall 1202 comprises a first side wall 12021 and a second side wall 12022, the second side wall 12022 connects the first side wall 12021 and the slot bottom wall 1201, and the second side wall 12022 extends from the first side wall 12021 to the slot bottom wall 1201 in an inclined manner. The driving member 41 comprises a second side surface 4112 connected with the first side surface 4111, and a convex rib 410 is arranged at the connection position of the first side surface 4111 and the second side surface 4112, and the convex rib 410 is arranged in the space formed by the second side wall 12022 and the slot bottom wall 1201. Of course, in other possible embodiments, the guide slot 120 can also be a T-shaped slot.

[0050] In some embodiments, referring to Figures 6 to 9 The first rotating body 1 comprises two first rotating discs 12, the two first rotating discs 12 are mirror-symmetrically distributed, and the two first rotating discs 12 are arranged at the two sides of the driving member 41 respectively. Each first rotating disc 12 is provided with a second rotating body 2 on the side away from the driving member 41. Correspondingly, the driving member 41 is roughly in a trapezoidal shape, the two first side surfaces 4111 of the driving member 41 are both inclined outward, the two second side surfaces 4112 of the driving member 41 are both parallel to the axis of the driving member 41, and the driving member 41 is provided with four convex ribs 410. By arranging the first rotating disc 12 on each side of the driving member 41, the two first rotating discs 12 cooperate with the two second rotating bodies 2. After the cover body is closed relative to the box body, the second tooth portion 221 of each second rotating body 2 is engaged with the first tooth portion 121 of each first rotating disc 12, which is beneficial to improve the locking stability between the cover body and the box body. Of course, in other possible embodiments, the first rotating body 1 can also comprise one first rotating disc 12, and the first rotating disc 12 cooperates with one second rotating body 2.

[0051] Referring to Figure 2 The first rotating disc 12 comprises a tooth area 12a, the tooth area 12a is a part of the second disc surface, the tooth area 12a is provided with the first tooth portion 121, and the second rotating body 2 is provided with a limiting rib 222, the limiting rib 222 is arranged in a spaced manner with the second tooth portion 221, and the limiting rib 222 is used for abutting against the first tooth portion 121 at the end of the tooth area 12a. By abutting the first tooth portion 121 with the limiting rib 222, the rotation angle of the second rotating body 2 is controlled, and the second tooth portion 221 of the second rotating body 2 slides back and forth in the tooth area 12a of the first rotating disc 12.

[0052] In this embodiment, the tooth area 12a is in a fan shape, and the central angle of the tooth area 12a is not greater than the central angle of the region of the first rotating disc 12 where the first tooth portion 121 is not arranged. That is to say, the area of the tooth area 12a is not more than half of the area of the first rotating disc 12. Of course, in other possible embodiments, the limiting rib 222 can also be omitted, and the second disc surface of the first rotating disc 12 is provided with the first tooth portion 121.

[0053] Referring to Figure 12The limiting rib 222 and the second tooth portion 221 are arranged in the fan-shaped area 22a of the second rotating body 2, and the central angle of the tooth area 12a is not less than the central angle of the fan-shaped area 22a, so that when the limiting rib 222 abuts against the first tooth portion 121 at one end of the tooth area 12a, the second tooth portion 221 engages with the first tooth portion 121 at the other end of the tooth area 12a, and the second tooth portion 221 does not disengage from the tooth area 12a.

[0054] In the embodiment, the first tooth portion 121 is a ratchet tooth, that is, the first tooth portion 121 is a one-way tooth. When it is needed to open the cover plate, since the first tooth portion 121 is a one-way tooth, the cover plate cannot be opened relative to the box body by moving the cover plate alone, and the first tooth portion 121 needs to be disengaged from the second tooth portion 221 by pressing the driving member 41, so that the cover body and the box body are locked more stably in the closed state.
