DETAILED DESCRIPTION

[0024] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] For reference Figures 1 to 6 ​​As shown, the application provides a charging pile plug protection device, which comprises: a protective cover 10, which is configured to be rotatably arranged on a charging pile body 20, the protective cover 10 has a protective position for protecting a charging pile plug 30 and a avoiding position for avoiding the charging pile plug 30; a first locking structure 40, the first locking structure 40 comprises a first locking part 41, the first locking part 41 is movably arranged along a first direction relative to the charging pile body 20, the first locking part 41 has a first locking state for locking the protective cover 10 in the protective position and a first unlocking state for allowing the protective cover 10 to rotate from the protective position to the avoiding position; a second locking structure 50, the first locking structure 40 and the second locking structure 50 are configured to be spaced apart along a second direction on the charging pile body 20, and the second locking structure 50 is located above the first locking structure 40, the second locking structure 50 comprises a second locking part 51, the second locking part 51 is movably arranged along the second direction relative to the charging pile body 20, the second locking structure 50 has a second locking state for locking the protective cover 10 in the avoiding position and a second unlocking state for allowing the protective cover 10 to rotate from the avoiding position to the protective position, the first direction and the second direction are arranged at an angle; a linkage assembly 60, the first locking part 41 and the second locking part 51 are synchronously locked or unlocked through the linkage assembly 60.

[0026] In the embodiment, the protective cover 10 is rotatably arranged on the charging pile body 20 to switch between the protective position and the avoiding position. The first locking part 41 is movably arranged along the first direction relative to the charging pile body 20 to enable the first locking part 41 to switch between the first locking state and the first unlocking state, and the second locking part 51 is movably arranged along the second direction relative to the charging pile body 20 to enable the second locking part 51 to switch between the second locking state and the second unlocking state. When the protective cover 10 is in the protective position, it can be covered on the outer periphery of the charging pile plug 30 to protect the charging pile plug 30, and when the protective cover 10 is in the avoiding position, the charging pile plug 30 can be exposed, which will not hinder the use of the charging pile plug 30 and is convenient to operate.

[0027] In the initial state, the protective cover 10 is in the protection position, the first locking part 41 is in the first locking state, and the second locking part 51 is in the second locking state. When the charging pile plug 30 needs to be used for charging, the first locking part 41 is switched to the first unlocking state. Since the first locking part 41 is locked or unlocked synchronously with the second locking part 51 through the linkage assembly 60, at this time, the second locking part 51 is in the second unlocking state, and the protective cover 10 can be rotated from the protection position to the avoidance position. When the protective cover 10 is rotated to the avoidance position, the second locking part 51 is in the second locking state again to lock the protective cover 10 in the avoidance position. When the charging is completed, the second locking part 51 is switched to the second unlocking state without using the charging pile plug 30. Since the first locking part 41 is locked or unlocked synchronously with the second locking part 51 through the linkage assembly 60, at this time, the first locking part 41 is in the first unlocking state, and the protective cover 10 can be rotated from the avoidance position to the protection position. When the protective cover 10 is rotated to the protection position, the first locking part 41 is in the first locking state again to lock the protective cover 10 in the protection position, so as to protect the charging pile plug 30 and prevent the charging pile plug 30 from being mechanically impacted and worn in daily use. As can be seen from the above, the charging pile plug 30 can be effectively shielded by the protective cover 10 when not in use, avoiding pollution and damage of dust, rainwater and the like to the charging pile plug 30, reducing the maintenance frequency of the charging pile plug 30, prolonging the service life of the charging pile plug, and being applicable to outdoor parking lots, highway service areas, and places with large number of people, so as to avoid direct contact of external personnel with the charging pile plug 30.

[0028] In one embodiment, the protective cover 10 is hinged to the charging pile body 20.

[0029] In combination with FIG. 1, Figures 1 to 6 In one embodiment of the present application, the linkage assembly 60 includes a first connecting structure 61 and a transmission structure 62.

The second end of the first connecting structure 61 is in transmission cooperation with the first end of the transmission structure 62. The second end of the transmission structure 62 is in transmission cooperation with the first locking part 41, so as to switch the first locking part 41 between the first locking state and the first unlocking state.

[0030] In the embodiment, the first end of the first connecting structure 61 is connected with the second locking part 51 and can move synchronously with the second locking part 51, so that the first connecting structure 61 can move along the second direction to the direction of approaching or moving away from the first locking part 41. When the first connecting structure 61 moves along the second direction, the second end of the first connecting structure 61 can be in transmission cooperation with the first end of the transmission structure 62, the second end of the transmission structure 62 is in transmission cooperation with the first locking part 41, and the first locking part 41 can be switched between the first locking state and the first unlocking state, thereby realizing the synchronous locking and unlocking of the first locking part 41 and the second locking part 51.

[0031] As shown in Figure 1 and 2 In one embodiment, the first connecting structure 61 is an L-shaped rod.

[0032] In combination with Figures 1 to 6 shown, in one embodiment of the application, the transmission structure 62 includes a rotating part 621, a first gear 622 and a second gear 623. One end of the rotating part 621 is configured to be rotatably connected with the charging pile body 20. The first gear 622 and the second gear 623 are spaced apart and sleeved on the rotating part 621 along the third direction. The second end of the first connecting structure 61 is provided with a toothed plate 70. The first gear 622 is in meshing cooperation with the toothed plate 70. The first locking part 41 is provided with a transmission part 48. The transmission part 48 includes a rack section 481. The second gear 623 is in meshing cooperation with the rack section 481. The rack section 481 includes a plurality of teeth spaced apart along the first direction.

[0033] In the embodiment, the third direction refers to the length direction of the rotating part 621. One end of the rotating part 621 is rotatably connected with the charging pile body 20, realizing the installation of the rotating part 621. The first gear 622 and the second gear 623 are fixedly sleeved on the rotating part 621. The second end of the first connecting structure 61 is provided with the toothed plate 70. The first gear 622 is in meshing cooperation with the toothed plate 70.

[0034] In combination with Figure 4When the second locking part 51 moves along the second direction to the direction away from the first locking part 41, the second locking part 51 can drive the tooth plate 70 to move through the first connecting structure 61, the movement of the tooth plate 70 drives the first gear 622 to rotate clockwise, the clockwise rotation of the first gear 622 drives the rotating part 621 to rotate clockwise, the clockwise rotation of the rotating part 621 drives the second gear 623 to rotate clockwise, the rotating movement of the second gear 623 is converted into linear movement through the rack segment 481, the clockwise rotation of the second gear 623 drives the rack segment 481 to move along the first direction to the direction away from the protective cover 10, thereby enabling the first locking part 41 to move along the first direction to the direction away from the protective cover 10, thereby enabling the first locking part 41 to be converted to the first unlocking state, at this time, the second locking part 51 is in the second unlocking state. When the second locking part 51 moves along the second direction to the direction close to the first locking part 41, the second locking part 51 can drive the tooth plate 70 to move through the first connecting structure 61, the movement of the tooth plate 70 drives the first gear 622 to rotate counterclockwise, the counterclockwise rotation of the first gear 622 drives the rotating part 621 to rotate counterclockwise, the counterclockwise rotation of the rotating part 621 drives the second gear 623 to rotate counterclockwise, the rotating movement of the second gear 623 is converted into linear movement through the rack segment 481, the counterclockwise rotation of the second gear 623 drives the rack segment 481 to move along the first direction to the direction close to the protective cover 10, thereby enabling the first locking part 41 to move along the first direction to the direction close to the protective cover 10, thereby enabling the first locking part 41 to be converted to the first locking state, at this time, the second locking part 51 is in the second locking state. Through the above setting, the synchronous locking and unlocking of the first locking part 41 and the second locking part 51 can be realized.

[0035] With reference to Figures 1 to 6 As shown in FIG. 6, in an embodiment of the present application, the pitch of the first gear 622 is smaller than the pitch of the second gear 623.

[0036] In the present embodiment, the protective cover 10 is provided with the first slot 11, when the first locking part 41 is inserted into the first slot 11, the first locking part 41 is in the first locking state, thereby enabling the protective cover 10 to be locked in the protective position, when the first locking part 41 is separated from the first slot 11, the first locking part 41 is in the first unlocking state, at this time, the protective cover 10 can be rotated from the protective position to the avoiding position. Since the pitch of the first gear 622 is smaller than the pitch of the second gear 623, in the process of force transmission, the rotating speed of the second gear 623 is slower than the first gear 622, in the same time, the distance of the rotation of the second gear 623 is longer, since the second gear 623 is engaged with the rack segment 481 of the first locking part 41, the rack segment 481 can be driven to move a farther distance along the first direction, thereby enabling the first locking part 41 to move a larger distance, so as to ensure that the first locking part 41 can be smoothly inserted into or separated from the first slot 11.

[0037] Referring to Figures 1 to 6 As shown in the drawings, in one embodiment of the present application, the protective cover 10 is provided with a first slot 11, and the first locking structure 40 further comprises a first mounting seat 42, which is configured to be mounted on the charging pile body 20, and the first locking portion 41 is movably arranged in the first mounting seat 42 along a first direction, so that the first locking portion 41 penetrates into or out of the first slot 11.

[0038] In this embodiment, when the first locking portion 41 is inserted into the slot, the first locking portion 41 is in a first locking state, which can lock the protective cover 10 in the protective position, and when the first locking portion 41 is separated from the first slot 11, the first locking portion 41 is in a first unlocking state. Through the above arrangement, the installation of the first locking portion 41 can be realized, and at the same time, the cooperation of the first locking portion 41 and the first slot 11 simplifies the locking and unlocking process of the protective cover 10. The user only needs to operate the first locking portion 41 to move along the first direction, so as to easily realize the locking or unlocking of the protective cover 10 without additional complex operation, thereby improving the user experience.

[0039] In one embodiment, the first slot 11 is a through slot.
