Description

Technical Field

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

[0002] New energy vehicle charging piles can be divided into public piles, special-purpose piles, and private piles according to the installation location. They can be fixed on the ground or wall, and installed in public buildings, residential community parking lots or charging stations. Currently, there is a movable new energy vehicle charging pile on the market, aiming to solve the problem that traditional fixed charging piles cannot be moved and can only charge at fixed positions. The movable new energy vehicle charging pile can provide charging services more flexibly.

[0003] When the current movable new energy vehicle charging pile is in use, the charging gun needs to be plugged into the vehicle charging port for charging. However, due to the mobility of the charging pile itself, even if the charging pile is provided with a self-locking mechanism, its fixity is weaker compared with the traditional fixed charging pile. The flexible charging cable will shake due to environmental factors such as strong wind, and the charging pile itself will also drive the charging cable to shake due to external forces such as vibrations generated by passing vehicles nearby, thereby affecting the stability of the connection between the charging gun and the charging port, and then resulting in poor contact and affecting the charging process. For this reason, a movable new energy power charging pile is proposed. Summary of the Invention

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

[0015] 1. The present invention sets a variable stiffness component so that when the charging gun is plugged into the vehicle charging port, the two-way air pump supplies air to the long tube of the airbag to inflate the long tube of the airbag, thereby shaping the folded bellows to prevent the charging gun from being loosened due to environmental factors such as strong winds or external forces such as ground vibrations caused by vehicles passing by, 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 sets a direction-adjusting electric push rod, so that when the curvature of the charging cable needs to be controlled in order to make the charging gun more suitable for the height of the current vehicle charging port, the direction-adjusting electric push rod can be used to stretch or shrink to a certain extent, thereby driving the corresponding telescopic air tube to stretch and retract, and 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, so that when the height difference between the charging gun and the charging port is too large, the folded corrugated tube can have a greater bending ability;

[0017] 3. In the present invention, by providing a storage box, when the gas in the airbag long tube is pumped out, the folding bellows will drive the charging gun to gradually bend downward until it is respectively clamped into the semi-circular storage groove and the storage box, realizing the storage of the folding bellows and the charging gun. At the same time, the control valve controls the multi-way gas transmission pipe, that is, the airbag long tube gas transmission channel, to close, and controls the branch pipe to communicate. The two-way air pump is used to transport gas into the storage box through the branch pipe and the multi-way cleaning pipe, so that the gas blows on the charging gun, and the dust and sundries attached to the charging gun are blown off, realizing the cleaning of the charging gun;

[0018] 4. In the present invention, by providing a protective bellows, the protective bellows with a bending function can be sleeved outside the airbag long tube to play a protective role for the airbag long tube. On the one hand, it can bear the wear between the airbag long tube and the sliding bracket instead of the airbag long tube. On the other hand, it can share the load on the airbag long tube when the steering electric push rod expands and contracts, and can also prevent dust from accumulating on the airbag long tube, resulting in dirt and damage to the outer skin of the airbag long tube;

[0019] 5. In the present invention, by providing protective sleeves, after the charging gun is recovered, the X-axis linear module drives the protective sleeves on both sides to merge on both sides of the folding bellows, so that the protective sleeves clamp the folding bellows in the bent state inside, and the protective sliding plate at the bottom covers one side of the storage box to close the storage groove. On the one hand, it can limit the movement of the folding bellows and the charging gun, prevent the flexible folding bellows from carrying the charging gun from shaking due to vibration, and on the other hand, it can play a protective role to prevent the structure from being damaged by object collision;

[0020] 6. In the present invention, by providing a moisture-proof buckle plate, after the charging gun is inserted into the charging port, the moisture-proof buckle plate will cover the outside of the charging port to prevent dust, rainwater, etc. from entering the charging port during the charging process, affecting the charging process.

[0021] 7. In the present invention, by providing a ranging plate, before charging, the driving frame will drive the charging pile body to the vicinity of the vehicle.

[0035] As Figures 1 to 8 shown, a movable new energy electric vehicle charging pile includes a driving vehicle frame 1. As Figure 1 shown, a Y-axis linear module 2 is fixedly installed on the top of the driving vehicle frame 1, and a charging pile body 3 is fixedly installed on the top of the driving end of the Y-axis linear module 2. In this embodiment, the Y-axis linear module 2 can adopt a common screw-type linear module on the market, so that the Y-axis linear module 2 has the functions of driving the charging pile body 3 to move forward and self-locking and limiting. As Figure 2 shown, a pump air chamber 301 is opened on one side of the charging pile body 3. As Figure 1 shown, a protective plate 4 is fixedly installed outside the pump air chamber 301. As Figure 3 shown, a folding bellows 5 is arranged inside the pump air chamber 301. As Figure 4 shown, one end of the folding bellows 5 extends to the outside of the pump air chamber 301 and is fixedly installed with a fixing frame 7. A charging cable 8 is arranged inside the folding bellows 5, and one end of the charging cable 8 is connected to the charging pile body 3. As Figure 3 shown, a charging gun 9 is fixedly installed on one side of the fixing frame 7. The other end of the folding bellows 5 is fixedly installed with a sliding bracket 14. The other end of the charging cable 8 is slidably installed inside the sliding bracket 14 and is connected to the charging pile body 3. The sliding bracket 14 is fixedly installed on the side wall of the protective plate 4. A variable stiffness component for flexibly changing the stiffness of the folding bellows 5 by pumping air is arranged on the periphery of the folding bellows 5. As Figure 2As shown, a plurality of monitoring probes 28 are arranged on the peripheral side of the top of the charging pile body 3; specifically, when the electric new energy charging pile is in use, when the vehicle owner needs to charge, the vehicle owner can make a reservation for the charging pile body 3 through a smart terminal such as a mobile phone. If the current charging pile body 3 is in an idle state, the vehicle position is observed through the monitoring probes 28 around the top of the charging pile body 3, and the driving frame 1 will drive the charging pile body 3 to move near the vehicle. The Y-axis linear module 2 drives the front charging pile body 3 to further approach the vehicle, and then the vehicle owner plugs the charging gun 9 into the charging port for charging. At this time, the variable stiffness component will change the folding bellows 5 by pumping air, so that the folding bellows 5 maintains a fixed shape, enabling the folding bellows 5 to 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 loosening the connection with the charging port due to environmental factors or external forces, which may affect the charging process.

[0036] As Figure 4 , Figure 5 shown, the variable stiffness component includes a plurality of airbag long tubes 6 arranged on the peripheral side of the folding bellows 5. The plurality of airbag long tubes 6 are evenly distributed along the axis of the folding bellows 5. One end of each airbag long tube 6 is fixedly installed on the side wall of the fixed frame 7. As Figure 6 shown, the other end of each airbag long tube 6 penetrates through the sliding bracket 14 and is fixedly installed with a telescopic air tube 13. As Figure 2 shown, a two-way air pump 10 is fixedly installed on the inner wall of the air pumping chamber 301. As Figure 3As shown, a multi-pass air pipe 11 and a two-way air pipe 12 are fixedly installed at the output end and the input end of the two-way air pump 10. One ends of a plurality of telescopic air pipes 13 are respectively communicated with a plurality of ports of the multi-pass air pipe 11. One end of the two-way air pipe 12 extends to the outside of the charging pile body 3. In this embodiment, filter components such as a filter screen and a filter element are arranged inside the two-way air pipe 12 for dust prevention and air filtration. Specifically, by setting a variable stiffness component, after the charging gun 9 is inserted into the vehicle charging port, the two-way air pump 10 conveys air to each airbag long pipe 6 through the multi-pass air pipe 11, causing the airbag long pipe 6 to inflate and bulge. As a result, the folding bellows 5 indirectly changes its stiffness under the influence of the airbag long pipe 6 filled with air on its circumferential side, shaping the originally arbitrarily bendable folding bellows 5. The combination of the folding bellows 5 and the airbag long pipe 6 is sleeved outside the charging cable 8, fixing the shape of the originally arbitrarily bendable charging cable 8, effectively preventing the charging gun 9 from becoming loose from the vehicle charging port due to external forces such as environmental factors like strong wind or ground vibrations caused by the passing of a vehicle, ensuring the stability of the charging pile during charging, and preventing phenomena such as unstable voltage or abnormal discharge caused by poor contact between the charging gun 9 and the charging port. At the same time, the folding bellows 5 plays an external protection role for the charging cable 8, effectively preventing external wear of the charging cable 8. When charging is completed, the Y-axis linear module 2 drives the front charging pile body 3 to retract, driving the charging gun 9 to separate from the charging port. Then, the two-way air pump 10 gradually extracts the air from the airbag long pipe 6, making the folding bellows 5 change its stiffness and driving the charging gun 9 to gradually droop, facilitating storage.

[0037] As Figure 6 shown, a steering electric push rod 19 is fixedly installed on the side wall of one end of each telescopic air pipe 13. The steering electric push rod 19 is parallel to the axis of the telescopic air pipe 13. The telescopic ends of the steering electric push rods 19 on the same side are fixedly connected to the telescopic ends of the telescopic air pipe 13. In this embodiment, the telescopic air pipe 13 is divided into a fixed end and a telescopic end. The fixed end of the steering electric push rod 19 is fixedly connected to the fixed end of the telescopic air pipe 13, and the telescopic end of the steering electric push rod 19 is fixedly connected to the telescopic end of the telescopic air pipe 13. Specifically, by setting the steering electric push rod 19, when it is necessary to control the bending degree of the charging cable 8 in order to make the charging gun 9 more adaptable to the height of the current vehicle charging port, the steering electric push rod 19 can be stretched or contracted to a certain extent, thereby driving the corresponding telescopic air pipe 13 to expand and contract, and then pulling or pushing the airbag long pipe 6 to change the relative positions of the plurality of airbag long pipes 6, enabling the airbag long pipe 6 as a whole to have a greater bending allowance. Thus, when there is a large height difference between the charging gun 9 and the charging port, the folding bellows 5 can have a greater bending ability.

[0038] As Figure 2As shown, a storage box 15 is fixedly installed on one side of the charging pile body 3. A recovery groove communicating with the inside of the storage box 15 is opened inside the charging pile body 3. A semi-circular storage groove 302 communicating with the inside of the storage box 15 is opened on the side wall of the charging pile body 3. The storage box 15 is located at the bottom of the air pumping chamber 301. The semi-circular storage groove 302 is located between the air pumping chamber 301 and the recovery groove. The position of the storage box 15 corresponds to the position of the charging gun 9. The position of the semi-circular storage groove 302 corresponds to the position of the folding bellows 5. As Figure 3 shown, a branch air pipe 16 is fixedly installed at the bottom of the multi-way air pipe 11. A multi-way cleaning pipe 18 is fixedly installed at the bottom end of the branch air pipe 16. Multiple ends of the multi-way cleaning pipe 18 all extend into the inside of the recovery groove. A control valve 17 is arranged on the branch air pipe 16. Specifically, by setting the storage box 15, when the gas in the airbag long pipe 6 is pumped out, the folding bellows 5 will drive the charging gun 9 to gradually bend downward until it is respectively stuck into the semi-circular storage groove 302 and the storage box 15, realizing the storage of the folding bellows 5 and the charging gun 9. At the same time, the control valve 17 controls the closing of the air delivery channel of the multi-way air pipe 11, that is, the airbag long pipe 6, and controls the branch air pipe 16 to be communicated. The two-way air pump 10 is used to deliver gas into the inside of the storage box 15 through the branch air pipe 16 and the multi-way cleaning pipe 18, so that the gas blows on the charging gun 9, and the dust and sundries attached to the charging gun 9 are blown off, realizing the cleaning of the charging gun 9.

[0039] As Figure 5 shown, protective bellows 20 are movably sleeved on the airbag long pipes 6. One ends of the protective bellows 20 are fixedly installed on the side walls of the fixed brackets 7. The other ends of the protective bellows 20 are fixedly sleeved on the telescopic ends of the telescopic air pipes 13. Specifically, by setting the protective bellows 20, the protective bellows 20 with a bending function can be sleeved outside the airbag long pipes 6 to play a protective role for the airbag long pipes 6. On the one hand, it can bear the wear between the airbag long pipes 6 and the sliding brackets 14 instead of the airbag long pipes 6. On the other hand, it can share the load on the airbag long pipes 6 when the telescopic electric push rods 19 stretch. It can also prevent dust from accumulating on the airbag long pipes 6, resulting in dirt and damage to the outer skin of the airbag long pipes 6.

[0040] As Figure 2 shown, a plurality of horizontally arranged X-axis linear modules 21 are fixedly installed on one side of the charging pile body 3. The plurality of X-axis linear modules 21 are evenly distributed on both sides of the semi-circular storage groove 302. As Figure 7As shown, the driving ends of the multiple X-axis linear modules 21 located on the same side are fixedly installed with the same protective sleeve 22. In this embodiment, the X-axis linear module 21 can adopt the common screw-type linear module on the market, so that the X-axis linear module 21 has the function of driving the protective sleeve 22 to move and self-locking and limiting. The two protective sleeves 22 are symmetrically distributed on both sides of the semicircular storage groove 302. The protective sleeve 22 is adapted to the folded bellows 5. The bottom of the protective sleeve 22 is fixedly installed with a protective slide plate 23, and the protective slide plate 23 is adapted to the storage box 15. Specifically, by setting the protective The sleeve 22 allows the protective sleeves 22 on both sides to be driven by the X-axis linear module 21 to approach and merge on both sides of the folding bellows 5 after the charging gun 9 is recovered and the surface dust is cleaned, so that the protective sleeve 22 can clamp the folding bellows 5 in the bent state inside, and the protective slide plate 23 at the bottom can cover 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 to prevent the folding bellows 5 in the flexible state from shaking due to vibration while carrying the charging gun 9. On the other hand, it can play a protective role to prevent structural damage caused by collision with objects.

[0041] like Figure 8 As shown, a moisture-proof buckle plate 24 is sleeved on the charging gun 9, and a plurality of annular clamping grooves 25 are opened on the side wall of the charging gun 9. A rubber sealing ring 26 is fixedly sleeved on the inner wall of the moisture-proof buckle plate 24. The rubber sealing ring 26 is located inside one of the moisture-proof buckle plates 24. A sealing pad 27 is fixedly installed on the side of the moisture-proof buckle plate 24 away from the charging pile body 3. Specifically, by setting the moisture-proof buckle plate 24, after the charging gun 9 is plugged into the charging port, the moisture-proof buckle plate 24 will cover the outside of the charging port, that is, cover the car body, and then with the help of the elasticity of the sealing pad 27 Improve the sealing performance of the moisture-proof buckle plate 24 to prevent external dust, rainwater, etc. from entering the charging port during charging and affecting the charging process. At the same time, a plurality of annular clamping grooves 25 are provided on the charging gun 9. Moisture-proof buckle plates 24 of different shapes and specifications can be replaced according to different vehicles, and the moisture-proof buckle plate 24 is sleeved on the annular clamping groove 25 at the corresponding position, so that the elastic rubber sealing ring 26 is clamped in the annular clamping groove 25, and the moisture-proof buckle plate 24 is limited to complete the rapid replacement of the moisture-proof buckle plate 24, thereby playing a moisture-proof and dust-proof role for different vehicles.

[0042] like Figure 2As shown in the figure, ranging electric push rods 29 are fixedly installed on both sides of the Y-axis linear module 2, and the telescopic ends of the two ranging electric push rods 29 are rotatably installed with the same ranging plate 30. Specifically, by setting the ranging plate 30, before charging, the driving frame 1 will drive the charging pile body 3 to approach the vehicle. The ranging electric push rod 29 controls the ranging plate 30 to move to one side of the vehicle body and contact the tire. Through the pressure sensor for position feedback, and in cooperation with the monitoring probe 28, the approximate distance between the current robot and the vehicle body in front is pre-measured. Then, the Y-axis linear module 2 controls the charging pile body 3 to approach the vehicle body by a specified distance and perform fine-tuning, realizing flexible control of the distance between the charging pile body 3 and the vehicle.

[0043] In summary: Before use: When the vehicle owner needs to charge, they can make a reservation for 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 probe 28 around the top of the charging pile body 3 observes the location of the vehicle. The driving frame 1 will drive the charging pile body 3 to approach the vehicle. The Y-axis linear module 2 drives the charging pile body 3 in front to get closer to the vehicle. The ranging electric push rod 29 controls the ranging plate 30 to move to one side of the vehicle body and contact the tire. Through the pressure sensor for position feedback, and in cooperation with the monitoring probe 28, the approximate distance between the current robot and the vehicle body in front is pre-measured. Then, the Y-axis linear module 2 controls the charging pile body 3 to approach the vehicle body by a specified distance and perform fine-tuning, realizing flexible control of the distance between the charging pile body 3 and the vehicle.

[0044] During use: The vehicle owner inserts the charging gun 9 into the charging port for charging. The moisture-proof buckling plate 24 will cover the outside of the charging port, that is, cover the vehicle body. Furthermore, by virtue of the elasticity of the sealing gasket 27, the sealing performance of the moisture-proof buckling plate 24 is improved, preventing dust, rainwater, etc. from entering the charging port during charging. At this time, the two-way air pump 10 delivers air to each airbag long tube 6 through the multi-way air delivery pipe 11, causing the airbag long tube 6 to inflate and bulge. As a result, the folding bellows 5 indirectly changes its stiffness under the influence of the airbag long tube 6 filled with air on its periphery, shaping the originally arbitrarily bendable folding bellows 5. The combination of the folding bellows 5 and the airbag long tube 6 is sleeved outside the charging cable 8, fixing the shape of the originally arbitrarily bendable charging cable 8, effectively preventing the charging gun 9 from becoming loose from the vehicle charging port due to external forces such as strong wind and other environmental factors or ground vibrations caused by the passing of vehicles, ensuring the stability of the charging pile during charging, and preventing phenomena such as unstable voltage or abnormal discharge caused by poor contact between the charging gun 9 and the charging port.

[0045] After use: When the charging is completed, the Y-axis linear module 2 drives the front charging pile body 3 to retract, driving the charging gun 9 to separate from the charging port. Then, the two-way air pump 10 gradually pumps out the gas in the airbag long tube 6, making the folding bellows 5 change its stiffness and driving the charging gun 9 to gradually hang down until it is respectively clamped into the semi-circular storage groove 302 and the storage box 15. At the same time, the control valve 17 controls the multi-pass gas pipeline 11, that is, the gas transmission channel of the airbag long tube 6 to close, and controls the branch gas pipeline 16 to communicate. The two-way air pump 10 is used to convey gas into the storage box 15 through the branch gas pipeline 16 and the multi-pass cleaning tube 18, so that the gas blows on the charging gun 9, and the dust and sundries attached to the charging gun 9 are blown off, realizing the cleaning of the charging gun 9. After that, 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 folding bellows 5 in the bent state inside, and the protective sliding plate 23 at the bottom covers one side of the storage box 15 to close the storage groove. On the one hand, it can limit the movement of the folding bellows 5 and the charging gun 9, preventing the folding bellows 5 in the flexible state from carrying the charging gun 9 from shaking due to vibration. On the other hand, it can play a protective role to prevent the structure from being damaged by object collision.
