Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a charging pile with multi-interface conversion function. Background Technology

[0002] A multi-interface conversion charging pile is an intelligent charging device that is compatible with multiple charging interface standards and protocols. By integrating physical interfaces, protocol conversion technology, and dynamic power distribution capabilities, it enables seamless connection between electric vehicles of different brands and regions and charging piles.

[0003] Currently, most mainstream charging stations are equipped with either seven-hole or nine-hole charging guns. Although electric vehicle charging interfaces are compatible with both types of guns, the installation location of the vehicle's charging port varies depending on the brand and model, such as the left, right, or rear of the vehicle. Even though the charging station can accommodate both seven-hole and nine-hole charging guns, the inherent cable routing of the charging gun often does not match the actual location of the vehicle's charging port. Users need to repeatedly drag the charging cable to adjust its position before they can plug in the gun for charging. This not only significantly reduces the convenience of daily use, but the frequent dragging action also accelerates the wear and aging of the charging cable, and may even cause damage to the internal circuitry, shortening the lifespan of the equipment. Therefore, we propose a charging station with multi-interface conversion functionality. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a charging pile with multi-interface conversion function.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A charging pile with multi-interface conversion function includes a charging pile body. A detection door is hinged to the side of the charging pile body, and a control panel is provided outside the detection door. A mounting cavity is formed by a recess in the middle of the charging pile body. Two charging gun bodies for charging vehicles are arranged in the mounting cavity. An adjustment mechanism for moving the charging gun bodies is also provided inside the charging pile body. The adjustment mechanism includes a servo motor fixed inside the charging pile body and a conveyor plate movably connected inside the servo motor. A gear is fixed on the output shaft of the servo motor. Two half-tooth rings mesh with the gear are arranged below the gear. A charging gun switching mechanism for rotating the two charging gun bodies is arranged between the two half-tooth rings and the conveyor plate. A charging gun separation mechanism for separating the two charging gun bodies is also arranged above the conveyor plate.

[0006] As a preferred embodiment of the present invention, the charging gun switching mechanism includes two base plates disposed above the conveyor plate, and a crossbar is fixed inside the charging pile body. The two base plates are slidably mounted on the outer wall of the crossbar. Two reciprocating rods are fixed at the bottom of the conveyor plate. Two limiting plates are disposed above the two base plates to limit the movement of two semi-gear rings. Two lifting plates are disposed above the two limiting plates to drive the two semi-gear rings to rise and fall. A servo motor is also provided to drive the two lifting plates to rise and fall. A support rod is disposed between the two limiting plates and the charging gun body to support the charging gun body. A reciprocating groove is also provided inside the charging pile body to facilitate the movement of the reciprocating rods. The lower half of the support rod is fixed to both the lifting plate and the limiting plate. A circular hole is provided in the middle of the semi-gear ring. The top of the support rod extends above the circular hole. The two semi-gear rings are spliced ​​together to form a gear. The device consists of meshing gear rings, two lifting discs joined together to form a circular disc, and two limiting discs joined together to form an elliptical disc. The output shaft of the first electro-hydraulic rod drives the lifting discs to rise and fall. A controller is also fixed on the side of the detection gate near the charging pile body. The servo motor and the first electro-hydraulic rod are connected to the controller via wires. The controller is controlled by the control panel to transmit signals to the controller, which controls the servo motor to rotate forward and backward and controls the extension and retraction of the first electro-hydraulic rod. The lifting discs drive the limiting discs to rise and fall, increasing the distance between the limiting discs and the base plate. At the same time, the lifting discs drive the half-gear rings to move upward, so that the half-gear rings contact the gears. The output shaft of the servo motor drives the gears to rotate, the gears drive the half-gear rings to rotate, the half-gear rings drive the lifting discs to rotate, and the lifting discs drive the support rods to rotate, which in turn drives the two charging gun bodies to rotate.

[0007] In a preferred embodiment of the present invention, two stop rods are fixed to the top of the two base plates to limit the positioning discs. Slots adapted to the stop rods are provided on the opposite sides of the two positioning discs. A receiving ring is fixed between the semi-tooth ring, the lifting disc, and the positioning discs. A baffle plate supporting the positioning discs is also fixed to the outer wall of the stop rods. A lifting plate is fixed to the telescopic end of the first electro-hydraulic rod. A groove is provided at the end of the lifting plate away from the first electro-hydraulic rod, and the two lifting discs are inserted into the groove. When the telescopic end of the first electro-hydraulic rod retracts, it drives the lifting plate to move upward, lifting... The plate drives two lifting plates to move upward through the groove. The two lifting plates drive two connecting rods to move two half-tooth rings and two limiting plates upward, so that the limiting plates move to the outside of the stop bar. The two half-tooth rings move to the bottom of the gear and mesh with the gear. The output shaft of the servo motor drives the gear to rotate 180 degrees. The gear drives the two half-tooth rings to rotate 180 degrees. The two half-tooth rings drive the two limiting plates and two lifting plates to rotate 180 degrees through the two connecting rods. The two limiting plates drive the two support rods to rotate 180 degrees. The two support rods drive the two charging gun bodies to rotate 180 degrees, so that the positions of the two charging gun bodies are exchanged.

[0008] As a preferred embodiment of the present invention, two locking rods are fixed on the opposite side of the two support rods, and two gathering rods are fixed on the opposite side of the two locking rods away from the two support rods. Two inserts are fixed at the bottom of the two gathering rods. A storage rod is also fixed on the inner wall of the charging pile body. The bottom of the storage rod is provided with a positioning hole that matches the two gathering rods. The inserts are M-shaped. Limiting holes that match the inserts are provided on the opposite side of the two lifting plates and the opposite side of the two limiting plates. The two gathering rods are spliced ​​together to form a cylinder, and after splicing, the two gathering rods are inserted into the positioning hole. When the support rod moves upward, the support rod drives the two locking rods to move upward, and the two locking rods drive the gathering rods to move upward, so that the gathering rods are inserted into the positioning hole. The gathering rods are limited by the cooperation between the gathering rods and the positioning hole, preventing the gathering rods from being separated by centrifugal force during rotation.

[0009] As a preferred embodiment of the present invention, a connecting rod is hinged to the top of the support rod, a storage ring is fixed to the top of the connecting rod, and a cable management plate is fixed to the outer wall of the support rod. A pressure rod is inserted above the cable management plate, and a spring is fixed between the pressure rod and the cable management plate. The connecting rod is V-shaped, and the top of the pressure rod contacts the lower half of the outer wall of the connecting rod. The top of the storage ring is recessed inward to form a placement groove that fits the charging gun body. When the charging gun body is removed from the storage ring, the spring releases its elastic force, causing the pressure rod to move upward, which pushes the connecting rod to rotate around the top of the support rod. The connecting rod causes the storage ring to move obliquely upward, increasing the distance between the two storage rings.

[0010] As a preferred embodiment of the present invention, the charging gun separation mechanism includes two sliders slidably mounted on the top of a conveyor plate. Two auxiliary pulleys are fixed to the top of the two sliders. Two main pulleys and two positioning blocks are also fixed to the top of the conveyor plate. An asynchronous motor is fixed to the bottom of the conveyor plate. The shaft of the asynchronous motor is fixed to one of the main pulleys. A belt is fitted between the main pulleys, auxiliary pulleys, and positioning blocks. Both ends of the belt are fixed to the two auxiliary pulleys respectively. The belt first passes over the outer wall of the auxiliary pulleys and then over the outer wall of the main pulleys. A groove is also provided on the top of the conveyor plate to facilitate the movement of the sliders. The tops of the auxiliary pulleys are fixed to the bottom of the base plate. The stepper motor is connected to the controller via a wire. The shaft of the asynchronous motor drives the main pulley connected to it to rotate counterclockwise. The main pulley drives the auxiliary pulley to move closer to the asynchronous motor via a belt. The asynchronous motor drives the slider to move along the slide groove, causing the slider to move closer to the asynchronous motor. The auxiliary pulley drives the stop rod to move closer to the asynchronous motor via the base plate. The stop rod drives the support rod to move closer to the asynchronous motor via the limit plate. The support rod drives the charging gun body to move closer to the asynchronous motor via the connecting rod and the storage ring, so that the charging gun body moves to the outside of the charging pile body, and the car is charged through the charging gun body.

[0011] As a preferred embodiment of the present invention, a second electro-hydraulic rod is fixed to the bottom of the conveyor plate. A boss is fixed to the side of the conveyor plate away from the base plate. A separating rod is provided inside the boss, and a slot is provided in the middle of the boss to facilitate the movement of the separating rod. The bottom of the separating rod passes through the slot and is fixed to the push rod of the second electro-hydraulic rod. The second electro-hydraulic rod is connected to the controller through a wire. The top of the separating rod contacts the belt. The telescopic end of the second electro-hydraulic rod pushes the separating rod to move along the slot. The separating rod moves away from the slider. The separating rod pushes the belt to move, causing the belt to pull two auxiliary pulleys to move to both sides of the conveyor plate, increasing the distance between the two auxiliary pulleys. The two auxiliary pulleys move in opposite directions through the two base plates. The two base plates drive two limiting discs to move in opposite directions through two stop rods. The two limiting discs drive two support rods to move in opposite directions, causing the two support rods to move to the outside of the charging pile body through two connecting rods and two receiving rings, thus moving the two charging gun bodies to the outside of the charging pile body.

[0012] As a preferred embodiment of the present invention, two limiting balls are rotatably connected to both sides of the slider, and two rollers are rotatably connected to the bottom of the two base plates. Limiting grooves for limiting the limiting balls are provided on both sides of the inner wall of the slide groove, and a moving groove for facilitating the movement of the rollers is provided at the bottom of the inner wall of the slide groove. By cooperating with the limiting balls and the limiting grooves, the slider is prevented from falling out of the slide groove during movement. The rollers can reduce the friction between the slider and the conveyor plate, thereby increasing the service life of the slider and the conveyor plate.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention, through the cooperation of an adjustment mechanism, a charging gun switching mechanism, a servo motor, gears, a gear ring, a support rod, a lifting plate, and a limiting plate, drives two charging guns to precisely rotate and switch to the mainstream seven-hole and nine-hole specifications, achieving precise same-side docking between the vehicle charging port and the corresponding compatible charging gun. This eliminates the tedious operation of repeatedly dragging cables, greatly improving the convenience of daily charging. It can also reduce the physical loss caused by cable dragging from the root, effectively slow down the aging rate, avoid safety hazards such as leakage and poor contact caused by cable outer sheath damage and internal circuit damage, and significantly extend its reliable service life. 2. This invention utilizes the combination of structures such as lifting plate, lifting plate, limiting plate, gathering rod, support rod and storage rod. The positioning hole of the storage rod forms a wrapping limit on the two gathering rods, which not only restricts the radial displacement of the gathering rods, but also constrains their circumferential movement. This counteracts the centrifugal force generated by the rotation of the support rod, prevents the two support rods from separating outward, and ensures that the two support rods always maintain a preset distance and coaxiality during rotation. This also prevents positional deviations when the charging gun is repositioned due to distance offset. 3. The present invention utilizes the cooperation of structures such as a limiting plate, a stop bar, a base plate, a baffle, a first electro-hydraulic rod, a lifting plate, and a lifting plate. The baffle provides stable support for the limiting plate, preventing it from sinking or tilting due to uneven force during movement. The synchronous movement of the limiting plate and the base plate can prevent positional deviations when the charging gun is switched, and prevent docking jamming and misalignment problems caused by limiting failure. 4. This invention utilizes the cooperation of a support rod, connecting rod, storage ring, cable tray, pressure rod, and spring. When the user removes the charging gun from the storage ring, the spring automatically releases its elasticity to push the pressure rod upward, which in turn drives the connecting rod to lift the storage ring simultaneously. This dynamic adjustment ensures that the storage ring is always at a height that better suits the user's operating habits, eliminating the need for the user to bend over or deliberately lower their head to align it. This is especially user-friendly for the elderly, children, or people with mobility impairments, making the entire process from taking out the gun to returning it smoother. 5. This invention uses the cooperation of a conveyor plate, main pulley, auxiliary pulley, asynchronous motor, belt, separating rod, and second electro-hydraulic rod to drive two charging gun bodies to move out of the charging pile body synchronously. It can provide services for one vehicle that needs seven-hole slow charging and one vehicle that needs nine-hole fast charging at the same time, reducing user waiting time, reducing the site rental and equipment investment costs for operators, and increasing the daily utilization rate of charging piles. 6. This invention utilizes the combination of structures such as sliders, rollers, limit balls, crossbars, and positioning blocks. The limit balls and positioning blocks form a bidirectional constraint, firmly locking the slider and the slide groove, preventing the slider from falling off at the source. The rollers directly contact the conveyor plate, converting the sliding friction between the slider and the conveyor plate into rolling friction, significantly reducing wear on the contact surface.

The lifting plate 505 drives the two lifting discs 506 through the groove. The lifting plate 506 moves upward, and the two lifting plates 506 drive the two connecting rods 514 to drive the two half-tooth rings 503 and the two limiting plates 507 to move upward, so that the limiting plates 507 move to the outside of the stop bar 508.

The asynchronous motor 524 drives the slider 529 to move along the slide groove, so that the slider 529 moves closer to the asynchronous motor 524. The auxiliary pulley 523 drives the stop rod 508 to move closer to the asynchronous motor 524 through the base plate 509. The stop rod 508 drives the support rod 512 to move closer to the asynchronous motor 524 through the limit plate 507.

A boss is fixed to the side of the conveyor plate 521 away from the bottom plate 509. A separating rod 526 is provided inside the boss, and a slot is provided in the middle of the boss to facilitate the movement of the separating rod 526. The bottom of the separating rod 526 passes through the slot and is fixed to the push rod of the second electro-hydraulic rod 527. The second electro-hydraulic rod 527 is connected to the controller through a wire. The top of the separating rod 526 contacts the belt 525. The telescopic end of the second electro-hydraulic rod 527 pushes the separating rod 526 to move along the slot. The separating rod 526 moves away from the slider 529. The lever 526 pushes the belt 525 to move, causing the belt 525 to pull the two auxiliary pulleys 523 to move to both sides of the conveyor plate 521, increasing the distance between the two auxiliary pulleys 523. The two auxiliary pulleys 523 move in opposite directions through the two base plates 509. The two base plates 509 drive the two limiting discs 507 to move in opposite directions through the two stop rods 508. The two limiting discs 507 drive the two support rods 512 to move in opposite directions, causing the two support rods 512 to move to both sides of the outside of the charging pile body 1 through the two connecting rods 516 and the two storage rings 517, thus moving the two charging gun bodies 4 to the outside of the charging pile body 1.

[0027] refer to Figure 12 , Figure 13 and Figure 14 As shown, two limiting balls 531 are rotatably connected to both sides of the slider 529, and two rollers 530 are rotatably connected to the bottom of the two base plates 509. Limiting grooves for limiting the limiting balls 531 are provided on both sides of the inner wall of the slide groove, and a moving groove for the rollers 530 to move is provided at the bottom of the inner wall of the slide groove. By cooperating with the limiting balls 531 and the limiting grooves, the slider 529 is prevented from falling out of the slide groove when moving. The rollers 530 can reduce the friction between the slider 529 and the conveyor plate 521, and increase the service life of the slider 529 and the conveyor plate 521.

[0028] The shaft of the asynchronous motor 524 drives the main pulley 522 connected to it to rotate counterclockwise. The main pulley 522 drives the auxiliary pulley 523 to move closer to the asynchronous motor 524 via the belt 525. The asynchronous motor 524 drives the slider 529 to move along the slide groove, causing the slider 529 to move closer to the asynchronous motor 524. The auxiliary pulley 523 drives the stop rod 508 to move closer to the asynchronous motor 524 via the base plate 509. The stop rod 508 drives the support rod 512 to move closer to the asynchronous motor 524 via the limiting plate 507. The support rod 512 drives the charging gun body 4 to move closer to the asynchronous motor 524 via the connecting rod 516 and the storage ring 517, so that the charging gun body 4 moves to the outside of the charging pile body 1 and charges the car through the charging gun body 4.

[0029] Working principle: When a car needs to be charged, and the car's charging port and the charging gun body 4 interface are on opposite sides, the control panel 3 transmits signals to the controller. The controller controls the servo motor 501 to rotate forward and backward, and controls the extension and retraction of the first electro-hydraulic rod 504. When the extension and retraction of the first electro-hydraulic rod 504 is reversed, it drives the lifting plate 505 to move upward. The lifting plate 505 drives the two lifting plates 506 to move upward through the groove. The two lifting plates 506 drive the two connecting rods 514 to drive the two half-tooth rings 503 and the two limiting plates 507 to move upward, so that the limiting plates 507 move to the outside of the stop lever 508. The two half-tooth rings 503 move to the bottom of the gear 502 and mesh with the gear 502. The two limiting plates 507... The two support rods 512 move upward, which in turn drives the two locking rods 534 to move upward. The two locking rods 534 then drive the two gathering rods 510 to move upward, so that the two gathering rods 510 come into contact and are inserted into the positioning hole. The output shaft of the servo motor 501 drives the gear 502 to rotate 180 degrees. The gear 502 drives the two half-tooth rings 503 to rotate 180 degrees. The two half-tooth rings 503 drive the two limiting plates 507 and the two lifting plates 506 to rotate 180 degrees through the two connecting rods 514. The two limiting plates 507 drive the two support rods 512 to rotate 180 degrees. The two support rods 512 drive the two charging gun bodies 4 to rotate 180 degrees, so that the positions of the two charging gun bodies 4 are exchanged, and the charging gun bodies 4 with the same interface as the car charging port are moved to the same side. The shaft of the asynchronous motor 524 drives the main pulley 522 connected to it to rotate counterclockwise. The main pulley 522 drives the auxiliary pulley 523 to move closer to the asynchronous motor 524 via the belt 525. The asynchronous motor 524 drives the slider 529 to move along the slide groove, causing the slider 529 to move closer to the asynchronous motor 524. The auxiliary pulley 523 drives the stop rod 508 to move closer to the asynchronous motor 524 via the base plate 509. The stop rod 508 drives the support rod 512 to move closer to the asynchronous motor 524 via the limiting plate 507. The support rod 512 drives the charging gun body 4 to move closer to the asynchronous motor 524 via the connecting rod 516 and the storage ring 517, so that the charging gun body 4 moves to the outside of the charging pile body 1 and charges the car through the charging gun body 4.
