[0056] On the one hand, if Figures 1-4 As shown, this embodiment provides a charging pile, which includes a shell 1, a lifting mechanism 2, a charging pile body 3, a security unlocking mechanism 4 and a control button 5. The shell 1 is arranged inside the ground to reduce damage to the exposed charging pile and reduce the area occupied by the charging pile. The charging pile body 3 is slidably connected to the inside of the shell 1. The lifting mechanism 2 is arranged in the shell 1 and connected to the charging pile body 3. The lifting mechanism 2 can be lifted and lowered along the first direction X to drive the charging pile body 3 to extend or retract into the shell 1. The control button 5 is connected to the lifting mechanism 2 to control the start or stop of the lifting mechanism 2.

[0057] The security unlocking mechanism 4 is arranged in the shell 1, avoiding occupying the space on the ground. The security unlocking mechanism 4 comprises a reference pedal 41 and a special-shaped lifting lever 42. The reference pedal 41 is slidingly connected to the shell 1 along the first direction X and partially located above the ground. The reference pedal 41 is arranged spaced apart from the charging pile body 3. The special-shaped lifting lever 42 has a locking state and an unlocking state. In the locking state, one end of the special-shaped lifting lever 42 is located below the reference pedal 41, and the other end is shielded above the control button 5. In the unlocking state, the reference pedal 41 moves along the first direction X to drive the special-shaped lifting lever 42 away from the control button 5, thereby removing the shielding of the control button 5. The user can operate the control button 5, thereby controlling the start or stop of the lifting mechanism 2.

[0058] By arranging the security unlocking mechanism 4, the vehicle wheels can only be pressed on the top of the reference pedal 41 to operate the control button 5 below the special-shaped lifting lever 42. The reference pedal 41 is arranged spaced apart from the charging pile body 3. The wheels are pressed on the reference pedal 41, and the vehicle is parked within a safe range. The charging pile body 3 is avoided from being scratched or blocked by the vehicle, thereby avoiding the problem that the charging pile is not convenient to lift.

[0059] Specifically, the first direction X is a vertical direction. The reference pedal 41 is in a strip shape and extends along the width direction of the parking space, so that the reference pedal 41 can correspond to both rear wheels of the vehicle, thereby increasing the force receiving area of the reference pedal 41. The lifting mechanism 2 is arranged on one side of the reference pedal 41. The lifting mechanism 2 comprises an electric telescopic rod 21 and a backing plate 22. The electric telescopic rod 21 can be lifted along the first direction X. One end of the electric telescopic rod 21 is fixed to the bottom of the shell 1, and the other end is fixedly connected with the backing plate 22. The charging pile body 3 is fixed to the side of the backing plate 22 away from the electric telescopic rod 21.

[0060] The control button 5 is electrically connected with the electric telescopic rod 21. The control button 5 is provided with a protective shell 411 above. In the locking state, the special-shaped lifting lever 42 abuts against the side of the protective shell 411 away from the control button 5, to fix the protective shell 411 and shield the control button 5, thereby ensuring that the control button 5 cannot be operated. In the unlocking state, the special-shaped lifting lever 42 is away from the protective shell 411. After the user moves the protective shell 411, the control button 5 can be operated.

[0061] Optionally, the special-shaped lifting lever 42 is slidingly connected to the shell 1 along the second direction Y. One end of the special-shaped lifting lever 42 below the reference pedal 41 is provided with an inclined portion. In the locking state, the inclined portion at least partially corresponds to the reference pedal 41. In the unlocking state, the reference pedal 41 can abut against the inclined portion to drive the special-shaped lifting lever 42 away from the control button 5.

[0062] Specifically, the second direction Y is a direction perpendicular to the extension direction of the reference pedal 41 in the horizontal plane. The special-shaped rocker 42 is inclined upward at one end corresponding to the reference pedal 41, forming an inclined surface. The wheel is pressed on the top of the reference pedal 41, and the reference pedal 41 moves into the housing 1 along the first direction X, thereby abutting and pressing the inclined surface, and the inclined surface is pressed to move along the second direction Y, so that the special-shaped rocker 42 moves towards the reference pedal 41, and further moves away from the protective shell 411, thereby releasing the fixation of the protective shell 411. The inclination angle of the inclined part ranges from 30° to 60°.

[0063] Optionally, the housing 1 comprises a first mounting frame 11, a second mounting frame 12 and a protective cover 13, the protective cover 13 is arranged between the first mounting frame 11 and the second mounting frame 12 and extends along the second direction Y, the charging pile body 3 is arranged in the first mounting frame 11, the reference pedal 41 is arranged in the second mounting frame 12, and the special-shaped rocker 42 is slidingly connected to the protective cover 13, so that the charging pile body 3 and the reference pedal 41 are arranged at intervals. When the wheel is pressed on the reference pedal 41, the vehicle can form a safety distance with the charging pile body 3, and the wheel is pressed on the second mounting frame 12 and the joint between the second mounting frame 12 and the ground at the same time, relying on the second mounting frame 12 to support the main pressure of the wheel, reducing the pressure on the reference pedal 41, and preventing damage to the reference pedal 41.

[0064] Specifically, the protective cover 13 is the same shape as the special-shaped rocker 42, and is arranged outside the special-shaped rocker 42, and the special-shaped rocker 42 can slide along the second direction Y in the protective cover 13. The reference pedal 41 is slidingly connected to the second mounting frame 12 along the first direction X, and the inner wall of the second mounting frame 12 is provided with a first sliding groove 121 along the first direction on both sides along the second direction Y, and the reference pedal 41 is fixedly connected with a first sliding block 412 on both sides along the second direction Y, and the first sliding block 412 is slidingly connected to the first sliding groove 121, thereby realizing the movement of the reference pedal 41 along the vertical direction.

[0065] Optionally, as shown in Figures 1-5 the housing 1 further comprises a cover plate 14 fixed to the charging pile body 3, the control button 5 is arranged on the cover plate 14, and the cover plate 14 is slidingly connected with a latch plate 43, one end of the latch plate 43 is connected to the special-shaped rocker 42, in the locked state, the other end of the latch plate 43 blocks the control button 5, and in the unlocked state, the latch plate 43 moves away from the control button 5 synchronously with the special-shaped rocker 42.

[0066] Specifically, the side of the cover plate 14 facing away from the charging pile body 3 is provided with a groove 142. The control button 5 and the protective shell 411 are installed in the groove 142. The protective shell 411 is rotationally connected to the side wall of the groove 142 along the second direction Y by a rotating rod. The latch plate 43 is slidingly connected to the cover plate 14, and in the locked state, the latch plate 43 extends above the protective shell 411 and abuts against the protective shell 411.

[0067] Optionally, the security unlocking mechanism 4 further comprises a reset elastic member 45 capable of deforming along the second direction Y, one end of the reset elastic member 45 abutting against the special-shaped lever 42, and the other end abutting against the shell 1. After the wheel is moved away from the reference pedal 41, the special-shaped lever 42 loses external force, and through the deformation of the reset elastic member 45, the special-shaped lever 42 can be restored to the locked state.

[0068] Specifically, in this embodiment, a reset sliding groove 141 is opened on the cover plate 7 at a position corresponding to the latch plate 43 along the second direction Y. The latch plate 43 is fixedly connected to one side of the bottom of the reset sliding groove 141. The reset sliding groove 141 is slidingly connected to the reset sliding groove 141. The reset elastic member 45 is arranged in the reset sliding groove 141. One end of the reset elastic member 45 abuts against the side wall of the reset sliding groove 141 close to the special-shaped lever 42, and the other end abuts against the reset sliding block 44. In this embodiment, the reset elastic member 45 can be a spring. In other embodiments, the reset elastic member 45 can be a structure such as an elastic rod or an elastic block. In other embodiments, one end of the reset elastic member 45 can directly abut against the special-shaped lever 42, and the other end can abut against the protective cover 13. The installation position of the reset elastic member 45 can be selected according to the actual installation space.

[0069] Further, in the locked state, the latch plate 43 and the special-shaped lever 42 are magnetically connected, and in the unlocked state, the latch plate 43 can be completely separated from the special-shaped lever 42.

[0070] Specifically, a magnet is fixedly arranged at the end of the latch plate 43, and a magnetic attraction member is fixedly arranged at the end of the special-shaped lever 42; or a magnetic attraction member is fixedly arranged at the end of the latch plate 43, and a magnet is fixedly arranged at the end of the special-shaped lever 42. In the unlocked state, the charging pile body 3 drives the cover plate 14 to rise to the ground, the latch plate 43 and the special-shaped lever 42 are not in the same plane, and the latch plate 43 and the special-shaped lever 42 are automatically disconnected; in the locked state, the latch plate 43 and the special-shaped lever 42 are in the same plane, and the latch plate 43 and the special-shaped lever 42 are magnetically connected, so as to ensure that the cover plate 14 will not be stuck with the special-shaped lever 42 during the lifting process, and when the cover plate 14 is reset, the special-shaped lever 42 can still smoothly form linkage with the latch plate 43.

[0071] Optionally, as shown in FIG. 6, the security unlocking mechanism 4 further comprises a protective cover 13 arranged on the cover plate 14, and the protective cover 13 is arranged on the side of the cover plate 14 facing away from the charging pile body 3. Figure 3 and Figure 6As shown, the security unlocking mechanism 4 also includes a pressure roller 47, which is rotatably connected to the reference pedal 41. In the unlocked state, the pressure roller 47 abuts against the inclined portion. By rotating the pressure roller 47 connected to the reference pedal 41, when the reference pedal 41 presses down the special-shaped tilt rod 42, the friction resistance between the reference pedal 41 and the special-shaped tilt rod 42 can be reduced by the rotation of the pressure roller 47.

[0072] Specifically, a pressure frame 46 extending along the first direction X is fixedly connected to a position corresponding to the inclined portion on the side of the reference pedal 41 facing the bottom of the second mounting frame 12. The pressure frame 46 is concave in shape. One end of the pressure frame 46 facing the inclined portion is rotatably connected to a pressure roller 47. The pressure roller 47 is cylindrical, with both ends of the pressure roller 47 rotatably connected to the pressure frame 46 via bearings. When unlocking, the reference pedal 41 descends, simultaneously driving the pressure frame 46 and the pressure roller 47 downward. As the pressure roller 47 descends, it gradually presses against the inclined portion, forcing the shaped lever 42 away from the control button 5.

[0073] Alternatively, as Figure 3 、 Figure 4 and Figure 7 As shown, the security unlocking mechanism 4 further includes a limiting support column 48, a limiting sleeve 49, and a first elastic member 410. One end of the limiting support column 48 is fixedly connected to the reference pedal 41, and the other end of the limiting support column 48 is slidably connected within the limiting sleeve 49 along the first direction X. The first elastic member 410 abuts the limiting support column 48 at one end and the limiting sleeve 49 at the other end. The first elastic member 410 is deformable in the first direction. In the unlocked state, the first elastic member 410 is compressed along the first direction X. When the unlocked state is released, the first elastic member 410 recovers its deformation, pushing the limiting support column 48 toward the ground, thereby driving the reference pedal 41 to move, causing the reference pedal 41 to be partially above the ground.

[0074] Specifically, there are two each of the limiting support column 48, the limiting sleeve 49, and the first elastic member 410. The limiting support column 48 is a cylinder extending along the first direction X. The two limiting support columns 48 are spaced apart in a direction perpendicular to the second direction in the horizontal plane and are fixedly connected to the bottom of the reference pedal 41. The inner diameter of the limiting sleeve 49 is larger than the diameter of the limiting support column 48. A limiting sleeve 49 is sleeved on the outside of each of the two limiting support columns 48 and fixed to the second mounting frame 12, so that the limiting support column 48 can slide in the limiting sleeve 49 along the first direction X. The first elastic member 410 is provided in each of the two limiting sleeves 49. In this embodiment, the first elastic member 410 is a spring.

[0075] Furthermore, if Figure 3 、 Figure 4 and Figures 7-9As shown, the charging pile further comprises an anti-fatigue mechanism 6, which comprises a support plate 61, a scissor assembly 62, a drive shaft 66, a gear set 63 and a toothed plate 64. The support plate 61 is fixed to the limiting sleeve 49, the scissor assembly 62 is connected to the support plate 61, the scissor assembly 62 can drive the support plate 61 to move along the first direction X, the drive shaft 66 is threadedly connected to the scissor assembly 62, the drive shaft 66 is connected to the gear set 63, the toothed plate 64 is fixed to the charging pile body 3 and is engaged with the gear set 63. The anti-fatigue mechanism 6 can avoid the problem that the first elastic member 410 is always in a compressed state when it is in an unlocked state for a long time, causing the first elastic member 410 to easily fatigue.

[0076] Specifically, the support plate 61 is fixed below the two limiting sleeves 49. The support plate 61 is fixed with a second sliding block 65 on one side along the second direction Y, and the second sliding block 65 is slidingly connected to a second sliding groove 122 on the inner wall of the second mounting frame 12 corresponding to one side.

[0077] The scissor assembly 62 comprises a first rotating plate 621, a second rotating plate 622, a sliding rail 623, a first control roller 624, a second control roller 625 and a threaded sleeve 626. The first rotating plate 621 is two, and the two first rotating plates 621 are respectively arranged in a direction perpendicular to the second direction in the horizontal plane and are respectively rotatably connected to the bottom of the second mounting frame 12 at one end and are respectively fixed with bearings at the other end. The first control roller 624 is rotatably arranged between the two first rotating plates 621 through the bearings.

[0078] The support plate 61 is fixedly connected with two sliding rails 623 along the second direction Y on one side facing the bottom of the second mounting frame 12, and the first control roller 624 is slidingly connected to the two sliding rails 623. The second rotating plate 622 is also two and is arranged transversely to the two first rotating plates 621. The middle portions of the first rotating plate 621 and the second rotating plate 622 are rotatably connected through a rotating rod, one end of the second rotating plate 622 is rotatably connected to the bottom of the support plate 61, the other end is respectively fixed with bearings, and the second control roller 625 is rotatably arranged between the two second rotating plates 622 through the bearings.

[0079] The bottom of the second mounting frame 12 is fixedly connected with two sliding rails 623 along the second direction Y, and the second control roller 625 is slidingly connected to the two sliding rails 623. The threaded sleeve 626 is rotatably connected to the second control roller 625 through a bearing. The drive shaft 66 is threadedly connected to the threaded sleeve 626 and rotatably connected to the inner wall of the second mounting frame 12 at one end and extends to the first mounting frame 11 along the second direction at the other end. A cross cover 15 is arranged between the first mounting frame 11 and the second mounting frame 12, the drive shaft 66 is installed in the cross cover 15 and rotatably connected to the cross cover 15 through a bearing. The gear set 63 comprises a first gear 631 and a second gear 632.

[0080] The driving shaft 66 is fixedly connected with the first gear 631 at one end of the first mounting frame 11. The toothed plate 64 is fixed to one side of the base plate 22 facing the first mounting frame 11 and is engaged with the second gear 632. The first gear 631 and the second gear 632 can be matched in speed change, facilitating the orderly connection of the displacement rate of the threaded sleeve 626 with the extension rate of the electric telescopic rod 21.

[0081] In the unlocked state, when the electric telescopic rod 21 drives the base plate 22 to rise, the base plate 22 synchronously drives the toothed plate 64 to rise. The rising of the toothed plate 64 will engage with the second gear 632, and the second gear 632 will synchronously engage with the first gear 631, so as to drive the driving shaft 66 to rotate slowly, drive the threaded sleeve 626 to move slowly along the second direction Y, and drive the second control roller 625 to move along the second direction Y. The movement of the second control roller 625 synchronously changes the support angle of the first rotating plate 621 and the second rotating plate 622 to reset, so as to drive the support plate 61 to drive the limiting sleeve 49 to descend, and the first elastic element 410 inside the limiting sleeve 49 gradually recovers elasticity downward.

[0082] Optionally, as shown in Figure 4 , Figure 10 and Figure 11 , the charging pile further comprises an automatic reset mechanism 7 arranged on the cover plate 14, which can automatically reset the protective shell 411.

[0083] Specifically, the automatic reset mechanism 7 comprises a reset extrusion rod 71 and a second elastic element 72. The side wall of the recess 142 close to the rotating rod side is provided with a sliding groove 143, and the protective shell 411 rotates towards the side of the sliding groove 143. The reset extrusion rod 71 is slidingly connected to the sliding groove 143, and part of the reset extrusion rod 71 is arranged outside the sliding groove 143. The second elastic element 72 is arranged in the sliding groove 143, and the second elastic element 72 can deform in a direction perpendicular to the second direction Y in the horizontal plane. The second elastic element 72 is a spring, one end of the second elastic element 72 is fixedly connected to the sliding groove 143, and the other end is fixedly connected to the reset extrusion rod 71. The second elastic element 72 can be a spring.

[0084] In the unlocked state, the protective shell 411 is rotated by external force, and after rotation, the protective shell 411 can be extruded and fitted with the end face of the reset extrusion rod 71 outside the sliding groove 143. The second elastic element 72 is compressed and deformed. After the external force applied to the protective shell 411 is removed, the second elastic element 72 restores the deformation, pushes the reset extrusion rod 71 to slide in the sliding groove 143, and thus extrudes the protective shell 411 to quickly flip and reset.

[0085] On the other hand, the embodiment provides a control method of the charging pile. The method is used for the charging pile and specifically comprises the following steps:

[0086] When the reference pedal 41 is pressed down by the vehicle entering the parking space, the reference pedal 41 is in contact with the special-shaped lifting rod 42, and the special-shaped lifting rod 42 is removed from the blocking of the control button 5, the operator triggers the control button 5, and the lifting mechanism 2 is started to lift the charging pile body 3 from the shell 1 to the ground to charge the vehicle;

[0087] After the charging is completed, the operator triggers the control button 5, and the lifting mechanism 2 is started to lower the charging pile body 3 from the ground to the shell 1, the vehicle is moved, the pressing on the reference pedal 41 is removed, the special-shaped lifting rod 42 is reset and blocks the control button 5.

[0088] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the scope of the present application.
