Description

Technical Field

[0001] The present invention relates to the technical field of new energy charging piles, and in particular to a movable electric new energy charging pile. Background Art

[0002] New energy vehicle charging piles can be divided into public piles, dedicated piles, and private piles according to the installation location. They can be fixed on the ground or wall and installed in parking lots or charging stations of public buildings and residential communities. There is currently a movable new energy vehicle charging pile on the market, which aims to solve the problem that traditional fixed charging piles cannot be moved and can only be charged in a fixed location. The movable new energy vehicle charging pile can provide charging services more flexibly.

[0003] When using the current mobile new energy vehicle charging pile, the charging gun needs to be plugged into the vehicle charging port for charging. However, since the charging pile itself is movable, even if the charging pile is equipped with a self-locking mechanism, its fixation is weaker than that of traditional fixed charging piles. The flexible charging cable will shake due to environmental factors such as strong winds, and the charging pile itself will also cause the charging cable to shake due to external forces such as vibrations generated by nearby vehicles passing by, thereby affecting the stability of the connection between the charging gun and the charging port, resulting in poor contact and affecting the charging process. For this reason, a mobile electric new energy charging pile is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that due to the mobility of the charging pile itself, even if the charging pile is equipped with a self-locking mechanism, its fixation is weaker than that of a traditional fixed charging pile.

One end of the plurality of telescopic air pipes is respectively connected to a plurality of ports of the multi-way air pipe, and one end of the two-way air pipe extends to the outside of the charging pile body.

[0008] Furthermore, a directional adjustment electric push rod is fixedly installed on the side wall of one end of the telescopic air tube, and the directional adjustment electric push rod is parallel to the axis of the telescopic air tube. The telescopic ends of the directional adjustment electric push rods on the same side are fixedly connected to the telescopic ends of the telescopic air tube.

[0009] Furthermore, a storage box is fixedly installed on one side of the charging pile body, a recovery groove connected to the interior of the storage box is opened inside the charging pile body, and a semicircular storage groove connected to the interior of the storage box is opened on the side wall of the charging pile body, the storage box is located at the bottom of the pump air chamber, and the semicircular storage groove is located between the pump air chamber and the storage groove, the position of the storage box corresponds to the position of the charging gun, and the semicircular storage groove corresponds to the position of the folded bellows, an air distribution pipe is fixedly installed at the bottom of the multi-way air supply pipe, and a multi-way cleaning pipe is fixedly installed at the bottom end of the air distribution pipe, and the multiple ends of the multi-way cleaning pipe extend to the interior of the storage groove, and a control valve is provided on the air distribution pipe.

[0010] Furthermore, a protective bellows is movably sleeved on the long tube of the airbag, one end of the protective bellows is fixedly mounted on the side wall of the fixing frame, and the other end of the protective bellows is fixedly sleeved on the telescopic end of the telescopic air pipe.

[0011] Furthermore, a plurality of horizontally arranged X-axis linear modules are fixedly installed on one side of the charging pile body, and the plurality of X-axis linear modules are evenly distributed on both sides of the semicircular storage groove.

[0013] Furthermore, distance measuring electric push rods are fixedly installed on both sides of the Y-axis linear module, and the telescopic ends of the two distance measuring electric push rods are rotatably installed with the same distance measuring plate.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention provides a variable stiffness component so that when the charging gun is plugged into the vehicle charging port, the bidirectional air pump supplies air to the long tube of the airbag, causing the long tube to inflate, thereby shaping the folded bellows. This prevents the charging gun from loosening due to environmental factors such as strong winds or external forces such as ground vibrations caused by passing vehicles, thereby ensuring the stability of the charging pile during charging and preventing voltage instability or abnormal discharge caused by poor contact between the charging gun and the charging port.

[0016] 2. The present invention provides a direction-adjusting electric push rod. When the curvature of the charging cable needs to be controlled in order to make the charging gun more adaptable to the height of the current vehicle charging port, the direction-adjusting electric push rod can be used to stretch or contract to a certain extent, thereby driving the corresponding telescopic air tube to expand or contract. Then, by pulling or pushing the airbag long tube, the relative positions of the multiple airbag long tubes are changed, so that the airbag long tube as a whole has a larger bending margin. Therefore, when the height difference between the charging gun and the charging port is too large, the folding corrugated tube can have a greater bending capacity.

[0017] 3. The present invention provides a storage box. When the gas in the long tube of the airbag is extracted, the folded bellows will drive the charging gun to gradually bend downward until it is respectively stuck in the semicircular storage groove and the storage box, thereby storing the folded bellows and the charging gun. At the same time, the control valve controls the closure of the multi-way air supply pipe, i.e., the air supply channel of the long tube of the airbag, and controls the connection of the air distribution pipe. A two-way air pump is used to supply air to the interior of the storage box through the air distribution pipe and the multi-way cleaning pipe, so that the gas blows on the charging gun, blowing off dust and debris attached to the charging gun, thereby cleaning the charging gun.

[0018] 4. The present invention provides a protective bellows, which has a bending function and can be sleeved on the outside of the airbag long tube to protect the airbag long tube. On the one hand, it can replace the airbag long tube to withstand the wear between the sliding bracket and the airbag long tube. On the other hand, it can share the load on the airbag long tube when the electric push rod is extended and retracted. It can also prevent dust from accumulating on the airbag long tube and causing the outer surface of the airbag long tube to become dirty and damaged.

[0019] 5. The present invention provides a protective sleeve so that after the charging gun is recovered, the protective sleeves on both sides of the X-axis linear module drive are merged with the two sides of the folding bellows, so that the protective sleeve clamps the folding bellows in the bent state inside, and the protective slide at the bottom covers one side of the storage box, closing the storage slot. On the one hand, it can limit the movement of the folding bellows and the charging gun, preventing the folding bellows in the flexible state from shaking due to vibration and carrying the charging gun, and on the other hand, it can play a protective role to prevent damage to the structure caused by collision with objects;

[0020] 6. The present invention provides a moisture-proof gusset plate, so that after the charging gun is plugged into the charging port, the moisture-proof gusset plate will cover the outside of the charging port, preventing dust, rainwater, etc. from entering the charging port during charging and affecting the charging process. At the same time, the moisture-proof gusset plate of different shapes and specifications can be replaced, and the moisture-proof gusset plate is sleeved on the annular clamping groove at the corresponding position, so that the elastic rubber sealing ring is clamped in the annular clamping groove to limit the moisture-proof gusset plate, completing the quick replacement of the moisture-proof gusset plate, thereby achieving moisture-proof and dust-proof effects for different vehicles;

[0021] 7. The present invention sets a distance measuring board so that before charging, the driving frame will drive the charging pile body to the vicinity of the vehicle. The distance measuring electric push rod controls the distance measuring board to move to the side of the vehicle body and contact the tire. The position feedback is provided by the pressure sensor, and the monitoring probe is used to pre-measure the approximate distance between the current robot and the vehicle body in front. The Y-axis linear module then controls the charging pile body to approach the specified distance to the vehicle body and perform fine adjustments to achieve flexible control of the distance between the charging pile body and the vehicle.

At this time, the variable stiffness component will change the folded bellows 5 by pumping air, so that the folded bellows 5 maintains a fixed shape, so that the folded bellows 5 can not only protect the internal charging cable 8, but also shape the charging cable 8, thereby improving the tightness of the connection between the charging gun 9 and the vehicle charging port, and preventing the charging gun 9 from being pulled by the charging cable 8 and loosened from the charging port due to environmental factors or external forces, thereby affecting the charging process.

[0036] like Figure 4 、 Figure 5 As shown, the variable stiffness assembly includes a plurality of airbag long tubes 6 arranged on the periphery of the folded bellows 5. The plurality of airbag long tubes 6 are evenly distributed along the axis of the folded bellows 5. One end of the airbag long tubes 6 is fixedly mounted on the side wall of the fixing frame 7. Figure 6 As shown, the other end of the airbag long tube 6 passes through the sliding bracket 14 and is fixedly installed with a telescopic air tube 13, as shown in FIG. Figure 2 As shown, a bidirectional air pump 10 is fixedly installed on the inner wall of the pump air chamber 301.

[0043] In summary: Before use: When the car owner needs to charge, he can make an appointment with the charging pile body 3 through a smart terminal such as a mobile phone. If the current charging pile body 3 is idle, the monitoring probes 28 around the top of the charging pile body 3 will observe the position of the vehicle. The driving frame 1 will drive the charging pile body 3 to the vicinity of the vehicle, and the Y-axis linear module 2 will drive the front charging pile body 3 closer to the vehicle.

The pressure sensor will provide position feedback, and the monitoring probe 28 will be used to pre-measure the approximate distance between the current robot and the vehicle body in front. Then, the Y-axis linear module 2 will control the charging pile body 3 to approach the vehicle body to a specified distance, and make fine adjustments to achieve flexible control of the distance between the charging pile body 3 and the vehicle.

[0044] During use: the owner plugs the charging gun 9 into the charging port for charging, and the moisture-proof gusset plate 24 will cover the outside of the charging port, that is, cover the car body, and then use the elasticity of the sealing pad 27 to improve the sealing performance of the moisture-proof gusset plate 24 to prevent external dust, rainwater, etc. from entering the charging port during charging. At this time, the two-way air pump 10 supplies air to each airbag long tube 6 through the multi-way air supply pipe 11, so that the airbag long tube 6 is inflated, so that the folded bellows 5 is indirectly changed under the influence of the airbag long tube 6 filled with air on the surrounding side. The rigidity is improved, so that the folding bellows 5 that can be bent at will is fixed in shape.

This ensures the stability of the charging pile during charging and prevents voltage instability or abnormal discharge caused by poor contact between the charging gun 9 and the charging port.

[0045] After use: When charging is finished, the Y-axis linear module 2 drives the front charging pile body 3 to retreat, driving the charging gun 9 to separate from the charging port, and then the two-way air pump 10 gradually extracts the gas in the airbag long tube 6, making the folded bellows 5 rigid and driving the charging gun 9 to gradually hang down until it is respectively stuck in the semicircular storage groove 302 and the storage box 15. At the same time, the control valve 17 controls the multi-way air supply pipe 11, that is, the air supply channel of the airbag long tube 6, to be closed, and controls the air distribution pipe 16 to be connected. The two-way air pump 10 is used to supply air to the inside of the storage box 15 through the air distribution pipe 16 and the multi-way cleaning pipe 18, so that the gas blows on the charging gun 9, so that The dust and debris attached to the charging gun 9 are blown off to clean the charging gun 9. Then the X-axis linear module 21 drives the protective sleeves 22 on both sides to approach and merge on both sides of the folding bellows 5, so that the protective sleeves 22 clamp the bent folding bellows 5 inside, and the protective slide plate 23 at the bottom covers one side of the storage box 15 to close the storage slot. On the one hand, it can limit the movement of the folding bellows 5 and the charging gun 9, and prevent the folding bellows 5 in the flexible state from shaking due to vibration with the charging gun 9. On the other hand, it can play a protective role to prevent structural damage caused by collision of objects.
