Description

Technical Field

[0001] The present invention relates to the field of charging piles, and in particular to a movable charging pile and a use method thereof. Background Art

[0002] A charging pile is a device that provides electric energy for electric vehicles (EVs). It allows electric vehicles to be connected to a power source for charging through conductive means. There are two main types of charging piles: AC charging piles (AC) and DC charging piles (DC); AC charging piles (AC): These charging piles are usually installed in parking spaces in public parking lots, residential areas or office buildings. They provide household or industrial standard AC power. Since the on-board charging piles of electric vehicles can generally only convert AC power into DC power, AC charging piles usually take longer to charge. The power of AC charging piles generally ranges from 3.3 kilowatts (kW) to 22 kilowatts; DC charging piles (DC): DC charging piles directly provide DC power to electric vehicles. The charging speed is much faster than that of AC charging piles, but due to their high output power, they generally require professional installation and maintenance. The power of DC charging piles can range from tens of kilowatts to hundreds of kilowatts, with 50 kilowatts, 120 kilowatts or even higher being common.

[0003] In recent years, with the continuous innovation of technology, more and more residents choose to use electric vehicles for transportation. However, with the gradual popularization of electric vehicles, there are fewer charging piles and charging difficulties. Some public parking spaces install charging piles for charging electric vehicles, and all parking spaces are equipped with charging piles. The number of charging piles is large and the cost is high. Some fuel vehicles are parked in public parking spaces, while the corresponding charging piles are idle, resulting in waste of charging piles. There is often a situation of "piles but no spaces". In order to solve the problem of charging difficulties, some parking spots have installed mobile charging piles and laid tracks on one side of the original public vehicles. According to charging needs, the charging piles can move freely on the tracks. Within the radiation range of the tracks, one pile can take into account multiple parking spaces, effectively alleviating the problem of charging difficulties in old communities, allowing residents without private parking spaces to charge at their doorsteps, ensuring that car owners can travel green without worries.

[0004] Chinese patent CN108248430B discloses a mobile electric vehicle charging pile device, including a solar power generation unit and a charging head. The solar power generation unit includes an arc-shaped carport board, an arc-shaped solar cell film attached to the outer peripheral surface of the arc-shaped carport board, a turning-over pivot, a turning-over motor, a turning frame, a cover plate, and a motor controller. The axis of the arc-shaped carport board coincides with the axis of the turning-over pivot. One end of the turning frame can be turned upside down on a concrete foundation through the turning-over pivot. The turning-over pivot is connected to the output main shaft of the turning-over motor by driving. The cover plate is fixed to the free end position of the turning frame. One side of the arc-shaped carport board is fixed to the cover plate. The arc-shaped carport board and the arc-shaped solar cell film can be stored in the arc-shaped receiving room to avoid erosion by wind, rain and dust. It can be used as a parking space, which is convenient for charging and does not take up space.

[0005] Chinese patent application CN112373341A discloses a mobile charging pile, including a charging pile body with a power cord and a charging gun, and a controller for controlling the charging process is arranged in the charging pile body; the key is that the charging pile also includes a guide rail, and the charging pile body is movably mounted on the guide rail, and can be moved after charging is completed to be used for charging other electric vehicles, avoiding the problem that the charging pile cannot be used because the charging position is occupied, thereby improving the utilization rate of the charging pile; at the same time, the position of the charging pile body can also be locked during the charging process, avoiding damage to the charging gun or the charging port of the electric vehicle due to the movement of the charging pile body, thereby improving safety.

[0007] In the prior art, when the parking space corresponding to the fixed charging pile is occupied by a vehicle that has not been charged, the fixed charging pile cannot be moved to other parking spaces for charging, resulting in idle and wasted charging piles. Each parking space needs to be equipped with a charging pile, and the number of charging piles is large and the cost is high. Some mobile charging piles are used, and the position of the charging piles can be adjusted. However, the mobile charging piles are mostly arranged on a track and moved manually. When the charging piles on multiple tracks are moved manually, the charging piles are easily caused to collide with each other, resulting in damage to the charging piles.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example: Reference Figure 1-Figure 11 A movable charging pile shown includes a plurality of chargers 1, each of which is equipped with a clamping assembly 2, and a moving assembly 3 is arranged below the charger 1;

[0046] The clamping assembly 2 includes an upper clamping plate 21 and a lower clamping plate 22, and the moving assembly 3 includes a toothed belt 31. The upper clamping plate 21 and the lower clamping plate 22 can be relatively moved and clamped on the toothed belt 31, and the toothed belt 31 can move;

[0047] The clamping assembly 2 also includes a bidirectional screw 23, an upper clamping plate 21 and a lower clamping plate 22 are both sleeved on the bidirectional screw 23 and threadedly matched with the bidirectional screw 23, and the thread directions of the two ends of the bidirectional screw 23 are opposite. The clamping assembly 2 also includes an unlocking gear 24 and two anti-collision units, and the anti-collision unit includes an unlocking block 25 and an unlocking rack 26. When the unlocking gear 24 rotates, it can drive the bidirectional screw 23 to rotate. The two anti-collision units are respectively arranged on both sides of the unlocking gear 24, and the unlocking rack 26 is meshed with the unlocking gear 24. When the unlocking block 25 moves toward the unlocking gear 24, it can drive the unlocking rack 26 to move;

[0048] When the lower clamping plate 22 and the upper clamping plate 21 move away from each other, the lower clamping plate 22 can fix the charger 1 .

[0049] The mobile assembly 3 is installed behind multiple parking spaces. When charging is needed, the bidirectional screw 23 is rotated, the upper clamping plate 21 moves downward on the bidirectional screw 23, and the lower clamping plate 22 moves upward on the bidirectional screw 23. The upper clamping plate 21 and the lower clamping plate 22 are clamped on the toothed belt 31. The movement of the toothed belt 31 drives the upper frame plate and the lower clamping plate 22 to move. The upper clamping plate 21 and the lower clamping plate 22 drive the charger 1 to move, and the charger 1 is moved to a position suitable for charging. The charger 1 is used to charge the vehicle. When the vehicle is charging, the upper clamping plate 21 and the lower clamping plate 22 move in opposite directions, the upper clamping plate 21 moves upward, and the lower clamping plate 22 moves downward, the clamping of the toothed belt 31 is released, and the lower clamping plate 22 moves downward to fix the charger 1. The charger 1 being charged cannot move. At this time, it has other When the parking space needs to be charged, the bidirectional screw 23 of the corresponding charger 1 rotates, and the upper clamping plate 21 and the lower clamping plate 22 are clamped on the toothed belt 31. At this time, the toothed belt 31 drives the other charger 1 to move, so that the other charger 1 moves to a position suitable for charging. When the other charger 1 hits the fixed charger 1 that is charging due to misoperation during the movement, the unlocking block 25 of the charger 1 is squeezed and moved during the movement, and the unlocking block 25 pushes the unlocking rack 26 to move, and the unlocking rack 26 drives the unlocking gear 24 to rotate, and the unlocking gear 24 drives the bidirectional screw 23 to rotate. During the movement, the upper clamping plate 21 and the lower clamping plate 22 of the charger 1 release the clamping of the toothed belt 31, and the movement of the toothed belt 31 will not continue to drive the corresponding charger 1 to move, thereby preventing the two chargers 1 from colliding.

[0050] When charging is needed, the upper clamping plate 21 and the lower clamping plate 22 are clamped on the toothed belt 31, so that the toothed belt 31 moves and drives the corresponding charger 1 to move, and moves the charger 1 to a suitable charging position, which can prevent some parking spaces from being occupied by fuel vehicles, resulting in the inability to charge the charger 1 corresponding to the parking space occupied by the fuel vehicle. At the same time, the number of chargers 1 arranged can be reduced, that is, it can meet the charging needs of fuel vehicles and electric vehicles when multiple parking spaces are mixed parked, and the position of the charger 1 can be moved, so as to flexibly select the charging position. When the charger 1 moves to the charging position, the lower clamping plate 22 moves downward and the upper clamping plate 21 moves upward to release the clamping of the toothed belt 31, so that the movement of the toothed belt 31 can drive other chargers 1 to move, and will not drive the charger 1 that is being charged to move. At the same time, the lower clamping plate 22 moves downward to fix the charger 1, and can fix the charger 1 that is being charged, preventing the charger 1 from moving during the charging process, causing the charging interface to be pulled and the charging to be disconnected, thereby improving the charging stability, and preventing the charging cable from being pulled and damaged, thereby increasing the service life of the charger 1.

[0051] When the charger 1 in the moving process collides with the charger 1 in the fixed state, the unlocking block 25 of the charger 1 in the moving process is squeezed, so that the corresponding upper clamping plate 21 and the lower clamping plate 22 move to release the clamping of the toothed belt 31, so that the movement of the toothed belt 31 will no longer drive the corresponding charger 1 to move, and the charger 1 in the moving process will be stopped to prevent the charger 1 from colliding and damaging.

[0052] At the same time, when the bidirectional screw 23 rotates and drives the upper clamping plate 21 and the lower clamping plate 22 to move away from each other, the bidirectional screw 23 drives the unlocking gear 24 to rotate, the unlocking gear 24 drives the unlocking rack 26 to move, the unlocking rack 26 drives the unlocking block 25 to move, and the lower clamping plate 22 moves downward to fix the charger 1, so that the unlocking block 25 will not extend when the charger 1 is fixed.

[0058] Further, refer to Figure 1-Figure 11 The moving assembly 3 includes two moving gears 34, a moving motor 32, a connecting shaft and a plurality of clamping blocks 33.
