[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] See also Figures 1 to 6As shown, the present invention provides a charging pile plug protection device, which includes: a protective cover 10, which is configured to be rotatably arranged on a charging pile body 20, and the protective cover 10 has a protection position for protecting a charging pile plug 30 and a avoidance position for avoiding the charging pile plug 30; a first locking structure 40, the first locking structure 40 includes a first locking portion 41, the first locking portion 41 is movably arranged along a first direction relative to the charging pile body 20, and the first locking portion 41 has a first locking state for locking the protective cover 10 in the protection position and a first unlocking state for allowing the protective cover 10 to rotate from the protection position to the avoidance position; a second locking structure 50, the first locking structure 50 includes a first locking portion 41, and the first locking portion 41 is movably arranged along a first direction relative to the charging pile body 20, and the first locking portion 41 has a first locking state for locking the protective cover 10 in the protection position and a first unlocking state for allowing the protective cover 10 to rotate from the protection position to the avoidance position. A locking structure 40 and a second locking structure 50 are constructed to be spaced apart on the charging pile body 20 along a second direction, and the second locking structure 50 is located above the first locking structure 40. The second locking structure 50 includes a second locking portion 51, and the second locking portion 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 that locks the protective cover 10 in an avoidance position and a second unlocking state that allows the protective cover 10 to rotate from the avoidance position to the protection position. The first direction is set at an angle to the second direction; a linkage assembly 60, the first locking portion 41 is synchronously locked or unlocked with the second locking portion 51 through the linkage assembly 60.

[0026] In this embodiment, the protective cover 10 is rotatably arranged on the charging pile body 20 to switch between the protective position and the avoidance position. The first locking portion 41 is movably arranged along the first direction relative to the charging pile body 20 so that the first locking portion 41 can switch between the first locked state and the first unlocked state, and the second locking portion 51 is movably arranged along the second direction relative to the charging pile body 20 so that the second locking portion 51 can switch between the second locked state and the second unlocked state. When the protective cover 10 is in the protective position, it can be arranged on the periphery of the charging pile plug 30 to protect the charging pile plug 30. When the protective cover 10 is in the avoidance 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 protective 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 is needed for charging, the first locking part 41 is switched to the first unlocking state. Since the first locking part 41 is synchronously locked or unlocked with the second locking part 51 through the linkage assembly 60, the second locking part 51 is in the second unlocking state at this time, and the protective cover 10 can be rotated from the protective position to the avoidance position. When the protective cover 10 is rotated to the avoidance position, the second locking part 51 is placed in the second locking state to lock the protective cover 10 in the avoidance position. When charging is completed and the charging pile plug 30 is not used, the second locking part 51 is switched to the second unlocking state. Since the first locking part 41 is locked or unlocked synchronously with the second locking part 51 through the linkage assembly 60, the first locking part 41 is in the first unlocking state at this time, 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 to protect the charging pile plug 30 and prevent the charging pile plug 30 from being subjected to mechanical impact and wear 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 dust, rainwater, etc. from contaminating and damaging the charging pile plug 30, which can not only reduce the maintenance frequency of the charging pile plug 30, but also extend the service life of the charging pile plug. It can be applied to outdoor parking lots, highway service areas, and places with large traffic, and can prevent external personnel from directly contacting the charging pile plug 30.

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

[0029] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the linkage assembly 60 includes a first connecting structure 61 and a transmission structure 62, the first end of the first connecting structure 61 is connected to the second locking portion 51 and can move synchronously with the second locking portion 51, the second end of the first connecting structure 61 is in transmission cooperation with the first end of the transmission structure 62, and the second end of the transmission structure 62 is in transmission cooperation with the first locking portion 41, so that the first locking portion 41 switches between a first locked state and a first unlocked state.

[0030] In this embodiment, the first end of the first connecting structure 61 is connected to the second locking portion 51 and can move synchronously with the second locking portion 51. Therefore, the first connecting structure 61 can move along the second direction toward or away from the first locking portion 41. The first connecting structure 61 moves along the second direction. At this time, the second end of the first connecting structure 61 can cooperate with the first end of the transmission structure 62, and the second end of the transmission structure 62 cooperates with the first locking portion 41, so that the first locking portion 41 can switch between the first locked state and the first unlocked state, thereby realizing the synchronous locking and unlocking of the first locking portion 41 and the second locking portion 51.

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

[0032] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the transmission structure 62 includes a rotating member 621, a first gear 622 and a second gear 623. One end of the rotating member 621 is constructed to be rotatably connected to the charging pile body 20. The first gear 622 and the second gear 623 are sleeved on the rotating member 621 at intervals along the third direction. A tooth plate 70 is provided at the second end of the first connecting structure 61, and the first gear 622 is meshed with the tooth plate 70. A transmission part 48 is provided on the first locking part 41, and the transmission part 48 includes a rack segment 481. The second gear 623 is meshed with the rack segment 481, and the rack segment 481 includes a plurality of teeth spaced apart along the first direction.

[0033] In this embodiment, the third direction refers to the length direction of the rotating member 621. One end of the rotating member 621 is rotatably connected to the charging pile body 20 to achieve the installation of the rotating member 621. The first gear 622 and the second gear 623 are fixedly sleeved on the rotating member 621. A tooth plate 70 is provided at the second end of the first connecting structure 61, and the first gear 622 is meshed with the tooth plate 70.

[0034] by Figure 4The installation position in is described as an example. When the second locking portion 51 moves along the second direction toward the direction away from the first locking portion 41, the second locking portion 51 can drive the tooth plate 70 to move through the first connecting structure 61. The movement of the tooth plate 70 will drive the first gear 622 to rotate clockwise, and the clockwise rotation of the first gear 622 will drive the rotating member 621 to rotate clockwise. The clockwise rotation of the rotating member 621 drives the second gear 623 to rotate clockwise. The rotational motion of the second gear 623 is converted into linear motion through the rack segment 481. The clockwise rotation of the second gear 623 drives the rack segment 481 to move along the first direction away from the protective cover 10, thereby enabling the first locking portion 41 to move along the first direction away from the protective cover 10, thereby converting the first locking portion 41 to the first unlocked state. At this time, the second locking portion 51 is in the second unlocked state. When the second locking portion 51 moves in the second direction toward the direction close to the first locking portion 41, the second locking portion 51 can drive the tooth plate 70 to move through the first connecting structure 61, and the movement of the tooth plate 70 will drive the first gear 622 to rotate counterclockwise, and the counterclockwise rotation of the first gear 622 will drive the rotating member 621 to rotate counterclockwise, and the counterclockwise rotation of the rotating member 621 drives the second gear 623 to rotate counterclockwise, and the rotational motion of the second gear 623 is converted into linear motion through the rack segment 481, and the counterclockwise rotation of the second gear 623 drives the rack segment 481 to move in the first direction toward the direction close to the protective cover 10, thereby enabling the first locking portion 41 to move in the first direction toward the direction close to the protective cover 10, thereby enabling the first locking portion 41 to be converted to the first locking state, and at this time, the second locking portion 51 is in the second locking state. Through the above arrangement, the synchronous locking and unlocking of the first locking portion 41 and the second locking portion 51 can be achieved.

[0035] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the tooth pitch of the first gear 622 is smaller than the tooth pitch of the second gear 623 .

[0036] In this embodiment, the protective cover 10 is provided with a first slot 11. When the first locking portion 41 is inserted into the slot, the first locking portion 41 is in a first locking state, and the protective cover 10 can be locked in the protective position. When the first locking portion 41 is disengaged from the first slot 11, the first locking portion 41 is in a first unlocking state, and at this time, the protective cover 10 can be rotated from the protective position to the avoidance position. Since the pitch of the first gear 622 is smaller than that of the second gear 623, during the force transmission process, the rotation speed of the second gear 623 will be slower than that of the first gear 622, and the second gear 623 rotates a longer distance in the same time. Since the second gear 623 is meshed with the rack segment 481 of the first locking portion 41, it can drive the rack segment 481 to move a longer distance along the first direction, so that the first locking portion 41 can move a greater distance to ensure that the first locking portion 41 can be smoothly inserted into the first slot 11 or removed from the first slot 11.

[0037] See also Figures 1 to 6 As shown, in one embodiment of the present invention, a first slot 11 is provided on the protective cover 10, and the first locking structure 40 also includes a first mounting seat 42, which is configured to be mounted on the charging pile body 20, and a first locking portion 41 is movably provided on the first mounting seat 42 along a first direction so that the first locking portion 41 can be inserted 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 the first locking state, and the protective cover 10 can be locked in the protective position. When the first locking portion 41 is disengaged from the first slot 11, the first locking portion 41 is in the first unlocking state. Through the above arrangement, the installation of the first locking portion 41 can be achieved. At the same time, the cooperation between 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 it along the first direction to easily lock or unlock the protective cover 10 without additional complicated operations, thereby improving the user experience.

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

[0040] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the first locking structure 40 also includes a limiting structure 43 and a first elastic member 44. The limiting structure 43 is installed on the first mounting seat 42. The limiting structure 43 has an accommodating cavity 431. A stop step 45 is arranged in the accommodating cavity 431. A pulling block 47 is arranged at the end of the first locking portion 41 away from the protective cover 10. The pulling block 47 is located outside the accommodating cavity 431 and forms a stop fit with the end of the limiting structure 43 away from the protective cover 10. Part of the first locking portion 41 is penetrated into the accommodating cavity 431. The first elastic member 44 is sleeved on the first locking portion 41 and is located in the accommodating cavity 431. A convex portion 46 is fixedly provided at one end of the first locking portion 41 close to the protective cover 10. The convex portion 46 is located in the accommodating cavity 431. Along the first direction, the first end of the first elastic member 44 forms a stop fit with the stop step 45, and the second end of the first elastic member 44 forms a stop fit with the convex portion 46.

[0041] In this embodiment, along the first direction, the pulling block 47 forms a stopper with the end of the limiting structure 43 away from the protective cover 10, and the protrusion 46 and the stopper step 45 can also form a stopper, which can effectively limit the movement range of the first locking part 41 and prevent the first locking part 41 from escaping from the first mounting seat 42. When the first locking part 41 needs to be in the first unlocked state, the pulling block 47 is pulled along the first direction away from the protective cover 10, so that the first locking part 41 overcomes the resistance of the first elastic member 44 and moves, so that it is escaping from the first slot 11, and then the pulling block 47 is released, and the restoring force of the first elastic member 44 will cause the first locking part 41 to automatically reset.

[0042] In one embodiment, the first elastic member 44 is a spring.

[0043] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the transmission portion 48 further includes a connecting section 482 , one end of which is fixedly connected to the pulling block 47 , and the other end of the connecting section 482 is fixedly connected to one end of the rack section 481 .

[0044] In one embodiment, the first mounting seat 42 is an L-shaped plate, which includes a first plate segment and a second plate segment that are perpendicular to each other. The first plate segment is fixedly connected to the charging pile body 20, and the second plate segment is used to install the limiting structure 43. The second plate segment is provided with a through hole that allows the first locking portion 41 to pass through.

[0045] In one embodiment, the limiting structure 43 is a cylindrical structure.

[0046] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the protrusion 46 is an annular structure, the first end of the first elastic member 44 is fixedly connected to the stop step 45 , and the second end of the first elastic member 44 is fixedly connected to the protrusion 46 .

[0047] In this embodiment, the protrusion 46 is an annular structure, which can ensure the contact area between the second end of the first elastic member 44 and the annular structure, thereby ensuring the stability of the connection between the two. When the first locking portion 41 needs to be in the first unlocked state, the pulling block 47 is pulled in the first direction away from the protective cover 10, thereby making the first locking portion 41 disengage from the first slot 11. At this time, the first elastic member 44 is compressed. When the first locking portion 41 is completely disengaged from the first slot 11, the pulling block 47 is released. Under the elastic restoring force of the first elastic member 44, the first locking portion 41 can move in the first direction toward the protective cover 10, thereby realizing the automatic reset of the first locking portion 41. In addition, along the first direction, the protrusion 46 can form a stop fit with the stop step 45, and the side of the annular structure away from the pulling block 47 forms a stop fit with the bottom wall of the end of the accommodating cavity 431 close to the protective cover 10, which can prevent the first locking portion 41 from disengaging.

[0048] See also Figures 1 to 6 As shown, in one embodiment of the present invention, a second slot 12 is provided on the protective cover 10, and the second locking structure 50 also includes a second mounting seat 52, which is constructed to be slidably provided on the charging pile body 20 along the second direction, and the second locking portion 51 is installed on the second mounting seat 52 so that the second locking portion 51 can be inserted into or removed from the second slot 12.

[0049] In this embodiment, when the second locking portion 51 is inserted into the second slot 12, the second locking portion 51 is in the second locking state, and the protective cover 10 can be locked in the avoidance position. When the second locking portion 51 is disengaged from the second slot 12, the second locking portion 51 is in the second unlocking state, and the protective cover 10 can be rotated from the avoidance position to the protection position. The second mounting seat 52 is provided to realize the installation of the second locking portion 51, and the second mounting seat 52 is slidably provided on the charging pile body 20 along the second direction. Since the second locking portion 51 is installed on the second mounting seat 52, the second locking portion 51 can be driven to move along the second direction toward or away from the first locking portion 41, so that the second locking portion 51 can be inserted into or out of the second slot 12, and the protective cover 10 can be locked and unlocked.

[0050] In one embodiment, the second slot 12 is a through slot.

[0051] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the second locking structure 50 also includes a second connecting structure 53 and a second elastic member 54. The second connecting structure 53 is constructed to be installed on the charging pile body 20 and is located on the side of the second mounting seat 52 close to the first locking structure 40. The second elastic member 54 is connected between the second mounting seat 52 and the second connecting structure 53. A through groove is provided on the second connecting structure 53. The second locking portion 51 is correspondingly provided in the through groove. The second locking portion 51 is slidably provided in the through groove along the second direction and can extend from the through groove to be inserted into the second slot 12.

[0052] In this embodiment, the second connection structure 53 is fixedly mounted on the charging pile body 20, and the second mounting seat 52 is located above the second connection structure 53. When the protective cover 10 needs to be locked in the avoidance position, the second mounting seat 52 is pulled in the second direction away from the first locking structure 40, and the second mounting seat 52 drives the second locking portion 51 to move away from the first locking structure 40 until the second locking portion 51 is disengaged from the second slot 12. At this time, the second elastic member 54 is stretched, and the second locking portion 51 is in the second unlocked state. Since the first locking portion 41 and the second locking portion 51 are unlocked synchronously, the first locking portion 41 is in the first unlocked state. Do not let go, so that the second mounting seat 52 remains in the current position. Then the protective cover 10 is rotated 90 degrees from the protective position to the avoidance position and the second slot 12 corresponds to the second locking portion 51, the second mounting seat 52 is released, and under the elastic restoring force of the second elastic member 54, the second elastic member 54 can pull the second mounting seat 52 to move along the second direction toward the first locking structure 40, and the second mounting seat 52 drives the second locking portion 51 to move along the second direction toward the first locking structure 40, so that the second locking portion 51 can extend from the through slot and insert into the second slot 12 to lock the protective cover 10 in the avoidance position. Similarly, when charging is completed, the protective cover 10 can be rotated and locked in the protective position according to the opposite operation, and the specific process will not be repeated.

[0053] In one embodiment, the second elastic member 54 is a spring.

[0054] In one embodiment, a rectangular slide groove 21 is provided on the charging pile body 20, and the second mounting seat 52 is a rectangular plate, which is slidably arranged in the rectangular slide groove 21 along the second direction.

[0057] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: a protective cover, a first locking structure, a second locking structure and a linkage assembly are provided. In the initial state, the protective cover is in the protective position, the first locking part is in the first locking state, and the second locking part is in the second locking state. When the charging pile plug is needed for charging, the first locking part is switched to the first unlocked state. Since the first locking part is synchronously locked or unlocked with the second locking part through the linkage assembly, the second locking part is in the second unlocked state at this time, and the protective cover can be rotated from the protective position to the avoidance position. When the protective cover is rotated to the avoidance position, the second locking part is put into the second locking state to lock the protective cover in the avoidance position. When charging is completed and the charging pile plug is not in use, the second locking part is switched to the second unlocked state. Since the first locking part is synchronously locked or unlocked with the second locking part through a linkage assembly, the first locking part is in the first unlocked state at this time, and the protective cover can be rotated from the avoidance position to the protection position. When the protective cover is rotated to the protection position, the first locking part is again in the first locked state to lock the protective cover in the protection position to protect the charging pile plug and prevent the charging pile plug from mechanical impact and wear during daily use.
