In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0056] On the one hand, if Figure 1-Figure 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 the damage of the charging pile exposed to the outside 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 housing 1 to avoid occupying the space on the ground. The security unlocking mechanism 4 includes a reference pedal 41 and a special-shaped tilting rod 42. The reference pedal 41 is slidably connected to the housing 1 along the first direction X, and is partially located above the ground. The reference pedal 41 is spaced apart from the charging pile body 3. The special-shaped tilting rod 42 has a locked state and an unlocked state. In the locked state, one end of the special-shaped tilting rod 42 is located below the reference pedal 41, and the other end is blocked above the control button 5. In the unlocked state, the reference pedal 41 moves along the first direction X to drive the special-shaped tilting rod 42 away from the control button 5, and the control button 5 is unblocked. The user can operate the control button 5, thereby controlling the start or stop of the lifting mechanism 2.

[0058] By setting up the security unlocking mechanism 4, the control button 5 below the special-shaped lever 42 can be operated only after the wheel of the vehicle is pressed on the top of the reference pedal 41. The reference pedal 41 is spaced apart from the charging pile body 3. The wheel is pressed on the reference pedal 41, and the vehicle is parked within a safe range, avoiding the problem that the charging pile body 3 is inconvenient to lift or lower due to scratches or being blocked by the vehicle.

[0059] Specifically, the first direction X is a vertical direction. The reference pedal 41 is in the shape of an elongated strip, extending along the width direction of the parking space, so that the reference pedal 41 can correspond to both rear wheels of the vehicle to increase the force-bearing area of ​​the reference pedal 41. The lifting mechanism 2 is arranged on one side of the reference pedal 41. The lifting mechanism 2 includes an electric telescopic rod 21 and a pad 22. The electric telescopic rod 21 can be lifted and lowered 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 to the pad 22. The charging pile body 3 is fixed to the side of the pad 22 facing away from the electric telescopic rod 21.

[0060] The control button 5 is electrically connected to the electric telescopic rod 21. A protective shell 411 is installed above the control button 5. In the locked state, the special-shaped tilting rod 42 abuts against the side of the protective shell 411 facing away from the control button 5 to fix the protective shell 411 and block the control button 5 to ensure that the control button 5 cannot be operated. In the unlocked state, the special-shaped tilting rod 42 is away from the protective shell 411. After the user moves away the protective shell 411, the control button 5 can be operated.

[0061] Optionally, the shaped lift rod 42 is slidably connected to the shell 1 along the second direction Y, and an inclined portion is provided at one end of the shaped lift rod 42 located below the reference pedal 41. In the locked state, the inclined portion at least partially corresponds to the reference pedal 41; in the unlocked state, the reference pedal 41 can abut against the inclined portion to push the shaped lift rod 42 away from the control button 5.

[0062] Specifically, the second direction Y is a direction in the horizontal plane perpendicular to the extension direction of the reference pedal 41. The end of the special-shaped lever 42 corresponding to the reference pedal 41 extends upwardly and obliquely to form an inclined surface. The wheel presses on the top of the reference pedal 41, and the reference pedal 41 moves into the shell 1 along the first direction X, thereby abutting against and squeezing the inclined surface. After being squeezed, the inclined surface moves along the second direction Y, so that the special-shaped lever 42 moves in the direction of the reference pedal 41, and then the special-shaped lever 42 moves away from the protective shell 411, releasing the fixation of the protective shell 411. The inclination angle range of the inclined portion is 30°-60°.

[0063] Optionally, the housing 1 includes 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 tilting rod 42 is slidably 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 presses on the reference pedal 41, the vehicle can form a safe distance with the charging pile body 3, and the wheel presses 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 has the same shape as the special-shaped tilting rod 42 and is sleeved on the outside of the special-shaped tilting rod 42. The special-shaped tilting rod 42 can slide in the protective cover 13 along the second direction Y. The reference pedal 41 is slidably connected to the second installation frame 12 along the first direction X. The inner wall of the second installation frame 12 is provided with first slide grooves 121 along the first direction on both sides along the first direction Y. The reference pedal 41 is fixedly connected with first sliders 412 on both sides along the second direction Y. The first sliders 412 are slidably connected to the first slide grooves 121, so as to realize the movement of the reference pedal 41 along the vertical direction.

[0065] Alternatively, if Figure 1-Figure 5 As shown, the shell 1 also includes a cover plate 14 fixed to the charging pile body 3, and the control button 5 is arranged on the cover plate 14. A latch plate 43 is slidably connected inside the cover plate 14, and one end of the latch plate 43 is connected to the special-shaped tilt rod 42. In the locked state, the other end of the latch plate 43 blocks the control button 5. In the unlocked state, the latch plate 43 moves away from the control button 5 synchronously with the special-shaped tilt rod 42.

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

[0067] Optionally, the security unlocking mechanism 4 also includes a reset elastic member 45 that can be deformed along the second direction Y, one end of the reset elastic member 45 abuts against the special-shaped lift rod 42, and the other end abuts against the shell 1. After the wheel moves away from the reference pedal 41, the special-shaped lift rod 42 loses external force, and the special-shaped lift rod 42 can be restored to a locked state through the deformation of the reset elastic member 45.

[0068] Specifically, in the present embodiment, a reset slot 141 is provided at a position on the cover plate 7 corresponding to the latch plate 43 along the second direction Y, a reset slider 44 is fixedly connected to one side of the latch plate 43 facing the bottom of the reset slot 141, the reset slider 44 is slidably connected to the reset slot 141, a reset elastic member 45 is arranged in the reset slot 141, one end of the reset elastic member 45 abuts against the side wall of the reset slot 141 close to the special-shaped tilting rod 42, and the other end abuts against the reset slider 44. In the present 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 tilting rod 42, and the other end abuts against the protective cover 13. The specific installation position of the reset elastic member 45 can be selected according to the actual installation space.

[0069] Furthermore, in the locked state, the latch plate 43 and the special-shaped tilting rod 42 are magnetically connected, and in the unlocked state, the latch plate 43 can be completely disengaged from the special-shaped tilting rod 42.

[0070] Specifically, a magnet is fixedly arranged at the end of the latch plate 43, and a magnetic attraction piece is fixedly arranged at the end of the special-shaped tilting rod 42; or a magnetic attraction piece is fixedly arranged at the end of the latch plate 43, and a magnet is fixedly arranged at the end of the special-shaped tilting rod 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 tilting rod 42 are not in the same plane, and the latch plate 43 and the special-shaped tilting rod 42 are automatically disconnected; in the locked state, the latch plate 43 and the special-shaped tilting rod 42 are in the same plane, and the latch plate 43 and the special-shaped tilting rod 42 are magnetically connected to ensure that the cover plate 14 will not be stuck with the special-shaped tilting rod 42 during the lifting process, and when the cover plate 14 is reset, the special-shaped tilting rod 42 can also form a linkage with the latch plate 43 smoothly.

[0071] Alternatively, if 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 rotatably connecting the pressure roller 47 to the reference pedal 41, when the reference pedal 41 presses down on the special-shaped lift rod 42, the friction resistance between the reference pedal 41 and the special-shaped lift 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 one 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 a cylinder, and both ends of the pressure roller 47 are rotatably connected to the pressure frame 46 through bearings. When unlocking, the reference pedal 41 descends, synchronously driving the pressure frame 46 and the pressure roller 47 to descend, and the descent of the pressure roller 47 will gradually come into contact with the inclined portion, thereby causing the special-shaped tilting rod 42 to move away from the control button 5.

[0073] Alternatively, if Figure 3 , Figure 4 and Figure 7 As shown, the security unlocking mechanism 4 further includes a limit support column 48, a limit sleeve 49 and a first elastic member 410. One end of the limit support column 48 is fixedly connected to the reference pedal 41, and the other end of the limit support column 48 is slidably connected to the limit sleeve 49 along the first direction X. One end of the first elastic member 410 abuts against the limit support column 48, and the other end abuts against the limit sleeve 49. The first elastic member 410 can deform along 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 limit support column 48 to move toward the ground, thereby driving the reference pedal 41 to move, so that the reference pedal 41 is partially located above the ground.

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

[0075] Furthermore, if Figure 3 , Figure 4 and Figure 7-9As shown, the charging pile also includes an anti-fatigue mechanism 6, which includes a support plate 61, a scissor assembly 62, a drive shaft 66, a gear set 63 and a tooth 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, and the tooth plate 64 is fixed to the charging pile body 3 and meshed 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 elastic fatigue of the first elastic member 410.

[0076] Specifically, the support plate 61 is fixed below the two limiting sleeves 49. A second slider 65 is fixed to one side of the support plate 61 along the second direction Y, and a second slide groove 122 along the first direction X is provided on the inner wall of the second mounting frame 12 corresponding to the second slider 65, and the second slider 65 is slidably connected to the second slide groove 122.

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

[0078] Two slide rails 623 along the second direction Y are fixedly connected to one side of the support plate 61 facing the bottom of the second installation frame 12, and the first centralized control roller 624 is slidably connected to the two slide rails 623. There are also two second rotating plates 622, which are arranged crosswise with the two first rotating plates 621. The middle parts 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, and the other end is respectively fixed with a bearing, and a second centralized control roller 625 is arranged between the two second rotating plates 622 to rotate together through the bearing.

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

[0080] The drive shaft 66 extends to one end of the first mounting frame 11 and is fixedly connected to the first gear 631. A toothed plate 64 is fixed to the side of the backing plate 22 facing the first mounting frame 11, and the toothed plate 64 is meshed with the second gear 632. The first gear 631 and the second gear 632 can achieve speed matching, which facilitates the orderly connection between the displacement rate of the threaded sleeve 626 and the telescopic rate of the electric telescopic rod 21.

[0081] In the unlocked state, when the electric telescopic rod 21 drives the pad 22 to rise, the pad 22 synchronously drives the toothed plate 64 to rise. The rising toothed plate 64 will mesh with the second gear 632. The second gear 632 synchronously meshes with the first gear 631, prompting the drive shaft 66 to rotate slowly, driving the threaded sleeve 626 to move slowly along the second direction Y, thereby driving the second control roller 625 to move along the second direction Y. The movement of the second control roller 625 synchronously pulls the support angle of the first rotating plate 621 and the second rotating plate 622 to reset the deformation, so that the support plate 61 drives the limiting sleeve 49 to descend, and the first elastic member 410 inside the limiting sleeve 49 gradually restores its elasticity downward.

[0082] Alternatively, if Figure 4 , Fig.10 and Fig.11 As shown, the charging pile also includes an automatic reset mechanism 7, which is arranged on the cover plate 14 and can facilitate automatic reset of the protective shell 411.

[0083] Specifically, the automatic reset mechanism 7 includes a reset rod 71 and a second elastic member 72. A sliding groove 143 is provided on the side wall of the groove 142 close to the rotating rod, and the protective shell 411 rotates toward one side of the sliding groove 143. The reset rod 71 is slidably connected to the sliding groove 143, and part of the reset rod 71 is arranged outside the sliding groove 143. The second elastic member 72 is arranged in the sliding groove 143, and the second elastic member 72 can be deformed in a direction perpendicular to the second direction Y in the horizontal plane. The second elastic member 72 is a spring, and one end of the second elastic member 72 is fixedly connected to the sliding groove 143, and the other end is fixedly connected to the reset rod 71. The second elastic member 72 can be a spring.

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

[0085] On the other hand, this embodiment provides a control method for a charging pile, which is used for the above-mentioned charging pile and specifically includes the following steps:

[0086] When the reference pedal 41 is pressed down by the vehicle entering the parking space, the reference pedal 41 is pressed and contacted with the special-shaped tilting rod 42, and drives the special-shaped tilting rod 42 to release the blocking limit of the control button 5. The operator triggers the control button 5 and starts the lifting mechanism 2 to lift the charging pile body 3 from the shell 1 to the ground to charge the vehicle;

[0087] After charging is completed, the operator triggers the control button 5 and starts the lifting mechanism 2 to lower the charging pile body 3 from the ground into the shell 1, move the vehicle, release the squeezing of the reference pedal 41, and reset the special-shaped lifting rod 42 to block the control button 5.

[0088] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
