Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle charging technology, specifically relating to a hidden electric vehicle charging pile. Background Technology

[0002] Since electric vehicles do not use crude oil resources but rely on electricity resources that are safe, readily available, and easy to store, they are considered clean energy vehicles and receive strong government support, which in turn leads to the widespread adoption of new energy vehicles. This results in the need to build a large number of new car charging stations.

[0003] Electric vehicle charging stations are expensive to build and maintain. Open-air charging stations are easily damaged by sun exposure and rain, and their paint will peel and age over time, affecting their appearance. They are also easily broken when a car reverses into a parking space, resulting in huge social and economic losses. Summary of the Invention

[0004] This invention provides a concealed electric vehicle charging station to solve the aforementioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a concealed electric vehicle charging station, comprising:

[0006] The shell is buried underground and has a first cavity. The upper end protrudes from the ground or is flush with the ground and has an inlet and outlet at the upper end and a drain outlet at the bottom. The drain outlet is suitable for connecting to the city's rainwater pipe.

[0007] The charging pile mechanism is located in the first cavity and is spaced apart from the inner wall of the housing. A cover plate is provided at the upper end, and the cover plate is suitable for covering the inlet and outlet.

[0008] A guide assembly is connected to the charging pile mechanism and slidably connected to the inner wall of the housing;

[0009] A filter plate is disposed on the lower side of the charging pile mechanism, and its circumference is connected to the inner wall of the housing; and

[0010] The first lifting mechanism is connected to the filter plate and the charging pile mechanism, and is used to drive the charging pile mechanism to rise or fall.

[0011] In one possible implementation, the charging pile mechanism includes a base and a charging pile body, with the first lifting mechanism and the guide assembly both connected to the base.

[0012] In one possible implementation, the charging pile body is provided with several receiving compartments, the openings of the receiving compartments facing one side of the charging pile mechanism, and a wire roller and an AGV charging trolley are provided in the receiving compartments. Cables are wound on the wire rollers, one end of the cables is electrically connected to the power output terminal of the charging pile mechanism, and the other end is electrically connected to the AGV charging trolley.

[0013] In one possible implementation, the AGV charging vehicle has a built-in power transmitting mechanism and a ring electromagnet, and the AGV charging vehicle is adapted to be attracted to the power absorption mechanism of an electric vehicle by the ring electromagnet.

[0014] In one possible implementation, the charging pile mechanism further includes a protective cover and a second lifting mechanism. A water baffle is provided on the lower side of the cover plate. The water baffle is located between the housing and the charging pile body and is connected to the cover plate. The protective cover is provided on the outside of the charging pile body. The upper end of the protective cover is adapted to be located between the water baffle and the charging pile body. The second lifting mechanism is connected to the base and the protective cover respectively to drive the protective cover to move up and down relative to the charging pile body.

[0015] In one possible implementation, the second lifting mechanism includes a guide rod, a first screw, and a first motor assembly. The two ends of the guide rod are respectively connected to the base and the cover plate. The first motor assembly is connected to the base. One end of the first screw is connected to the power output end of the first motor assembly, and the other end is rotatably connected to the cover plate. The protective cover is slidably connected to the guide rod and screwed to the first screw.

[0016] In one possible implementation, the guide assembly includes two guide members, and the inner walls on both sides of the housing are provided with grooves in the vertical direction. The guide members are rigid members, one end of each of the two guide members is connected to the base, and the other end is slidably engaged with the two grooves respectively.

[0017] In one possible implementation, the first lifting mechanism includes a support plate, a sliding shoe, a second screw, and a second motor assembly. One end of the support plate is hinged to the base, and the other end is hinged to the sliding shoe. The sliding shoe is disposed on the filter plate and slides in cooperation with the filter plate. The second motor assembly is connected to the inner wall of the housing. One end of the second screw is connected to the power output end of the second motor assembly, and the other end is rotatably connected to the inner wall of the housing. The second screw passes through the sliding shoe and is threadedly engaged with the sliding shoe.

[0018] In one possible implementation, the housing is further provided with a second cavity, which is located on one side of the first cavity and communicates with the first cavity. A cleaning component is installed on the bottom of the slipper to sweep the debris on the filter plate into the second cavity.

[0019] In one possible implementation, a collection box and a negative pressure pump are also included. The housing is further provided with a third chamber, a fourth chamber, a fifth chamber, and a negative pressure pipe. The third chamber is located on one side of the second chamber, with its opening facing the second chamber. The bottom of the second chamber is inclined towards the third chamber, allowing the waste in the second chamber to slide freely into the third chamber. The fourth chamber is located above the second chamber and houses the collection box. One end of the negative pressure pipe is connected to the third chamber, and the other end is connected to the air inlet of the collection box. The fifth chamber is located on one side of the fourth chamber, and the negative pressure pump is located in the fifth chamber. The negative pressure port of the negative pressure pump is connected to the air outlet of the collection box, and the exhaust port of the negative pressure pump is connected to the first chamber.

[0020] The beneficial effects of the concealed electric vehicle charging pile provided by this invention are as follows: Compared with the prior art, the concealed electric vehicle charging pile provided by this invention buries the shell in a pre-dug pit and installs the charging pile mechanism inside the shell. The charging pile mechanism is driven to extend or retract into the ground by a first lifting mechanism, and the inlet and outlet on the shell are covered by a cover plate. This effectively prevents the charging pile from being exposed to sunlight, wind and rain, or being broken by impact, thus significantly extending the service life of the charging pile. At the same time, the charging pile mechanism is spaced apart from the inner wall of the shell, and a drain outlet connected to the urban rainwater pipe is set at the bottom of the shell. Even if rainwater seeps into the shell, it will flow along the inner wall of the shell to the bottom of the shell and then into the urban rainwater pipe through the drain outlet. The filter plate can effectively prevent water accumulation inside the shell due to blockage of the drain outlet. This ensures that even if rainwater seeps into the shell, the inside of the shell remains dry, preventing the charging pile from getting damp and damaged, and extending the service life of the charging pile.

[0041] Please refer to the following: Figures 1 to 6 The concealed electric vehicle charging station provided by the present invention will now be described.

[0042] The concealed electric vehicle charging pile includes a housing 10, a charging pile mechanism, a guide assembly, a filter plate 12, and a first lifting mechanism. The housing 10 is buried underground and has a first cavity. The upper end protrudes from or is flush with the ground and has an inlet and outlet at the upper end. The bottom has a drain outlet 11, which is suitable for connecting to urban rainwater pipes. The charging pile mechanism is located in the first cavity and is spaced apart from the inner wall of the housing 10. The upper end has a cover plate 21, which is suitable for covering the inlet and outlet. The guide assembly is connected to the charging pile mechanism and is slidably connected to the inner wall of the housing 10. The filter plate 12 is located on the lower side of the charging pile mechanism and is connected to the inner wall of the housing 10 around its perimeter. The first lifting mechanism is connected to the filter plate 12 and the charging pile mechanism and is used to drive the charging pile mechanism to rise or fall.

[0043] The beneficial effects of the concealed electric vehicle charging pile provided in this embodiment of the invention are as follows: Compared with the prior art, the concealed electric vehicle charging pile provided in this embodiment of the invention buries the housing 10 in a pre-dug pit and installs the charging pile mechanism inside the housing 10. The charging pile mechanism is driven to extend or retract into the ground by the first lifting mechanism, and the inlet and outlet on the housing 10 are covered by the cover plate 21. This can effectively prevent the charging pile from being exposed to sunlight, wind and rain, or being broken by impact, and greatly extend the service life of the charging pile. At the same time, the charging pile mechanism is spaced apart from the inner wall of the housing 10, and a drain outlet 11 connected to the urban rainwater pipe is provided at the bottom of the housing 10. Even if rainwater seeps into the interior of the housing 10, it will flow along the inner wall of the housing 10 to the bottom of the housing 10, and then flow into the urban rainwater pipe through the drain outlet 11. The filter plate 12 can effectively prevent water accumulation inside the housing 10 due to blockage of the drain outlet 11. This ensures that even if rainwater seeps into the housing 10, the interior of the housing 10 can be kept dry, preventing the charging pile from getting damp and damaged, and extending the service life of the charging pile.

[0044] like Figures 1 to 4 As shown, in a specific embodiment of the concealed electric vehicle charging pile provided in this embodiment, the charging pile mechanism includes a base 22 and a charging pile body 23, and the first lifting mechanism and the guide component are both connected to the base 22.

[0045] like Figures 1 to 5 As shown, in a specific embodiment of the hidden electric vehicle charging pile provided in this example, the charging pile body 23 is provided with several receiving compartments, the openings of which face one side of the charging pile mechanism. Inside the receiving compartments are wire rollers 25 and AGV charging trolleys 24. Wire rollers 25 are wound with cables, one end of which is electrically connected to the power output end of the charging pile mechanism, and the other end is electrically connected to the AGV charging trolleys 24.

[0046] like Figure 1 As shown, in a specific embodiment of the hidden electric vehicle charging pile provided in this example, the AGV charging vehicle 24 has a built-in power transmitting mechanism and a ring electromagnet. The AGV charging vehicle 24 is adapted to be attracted to the power absorption mechanism of the electric vehicle through the ring electromagnet. The power transmitting mechanism includes a transmitting coil, and the power absorption mechanism includes a receiving coil. The transmitting coil converts high-frequency alternating current into a high-frequency alternating magnetic field. The receiving coil at the electric vehicle end receives the magnetic field energy through magnetic coupling and restores it to high-frequency electrical energy.

[0047] It should be noted that AGVs (Automated Guided Vehicles) are also known as unmanned transport vehicles, automated guided vehicles, or laser-guided vehicles. Their most significant characteristic is that they are driverless. AGVs are equipped with an automatic guidance system, ensuring that they can automatically travel along a predetermined route without manual guidance. Another feature of AGVs is their high flexibility, high degree of automation and intelligence. The AGV's travel path can be flexibly changed according to requirements, and the cost of changing the operating path is very low compared to traditional conveyor belts and rigid conveyor belts.

[0048] This embodiment can be connected to an intelligent control system. A QR code corresponding to each parking space is engraved on the cover plate 21. After parking the car, the user can scan the corresponding QR code and fill in the relevant information to raise the charging pile mechanism. Then, the AGV charging trolley 24 automatically walks to the underside of the car's energy absorption mechanism, and then the annular electromagnet is energized to attract the AGV charging trolley 24 to the underside of the car, so that the energy transmitting mechanism of the AGV charging trolley 24 is in contact with the car's energy absorption mechanism for charging. After charging is completed, the power supply to the annular electromagnet is automatically cut off, the AGV charging trolley 24 falls down, and automatically returns to the charging pile mechanism. When the AGV charging trolley 24 moves outward, the wire roller 25 releases the cable. During the resetting process of the AGV charging trolley 24, the wire roller 25 retracts the cable.

[0049] like Figures 1 to 4 As shown, in a specific embodiment of the concealed electric vehicle charging pile provided in this embodiment, the charging pile mechanism further includes a protective cover 31 and a second lifting mechanism. A water baffle 26 is provided on the lower side of the cover plate 21. The water baffle 26 is located between the housing 10 and the charging pile body 23 and is connected to the cover plate 21. The protective cover 31 is covered on the outside of the charging pile body 23. The upper end of the protective cover 31 is adapted to be located between the water baffle 26 and the charging pile body 23. The second lifting mechanism is connected to the base 22 and the protective cover 31 respectively to drive the protective cover 31 to move up and down relative to the charging pile body 23.

[0050] like Figures 1 to 5 As shown, in a specific embodiment of the concealed electric vehicle charging pile provided in this embodiment, the second lifting mechanism includes a guide rod 32, a first screw 33, and a first motor assembly 34. The two ends of the guide rod 32 are respectively connected to the base 22 and the cover plate 21. The first motor assembly 34 is connected to the base 22. One end of the first screw 33 is connected to the power output end of the first motor assembly 34, and the other end is rotatably connected to the cover plate 21. The protective cover 31 is slidably connected to the guide rod 32 and screwed to the first screw 33.

[0051] It should be noted that during the charging process, the charging pile mechanism is in a raised state, with the charging pile body 23 exposed outside the housing 10. At this time, the first motor assembly 34 is activated to drive the protective cover 31 to rise through the first screw 33, so that the upper end of the protective cover 31 is higher than the lower end of the baffle 26. The upper end of the protective cover 31 is spaced apart from the cover plate 21, so that rainwater, dust, and garbage can directly enter the first cavity through the gap between the protective cover 31 and the housing 10, thereby effectively preventing rainwater, dust, and garbage from entering the charging pile body 23 during the charging process. At this time, the cable connecting the charging pile body 23 and the AGV charging trolley 24 passes through the gap between the protective cover 31 and the cover plate 21 and the baffle 26.

[0052] like Figures 1 to 5 As shown, in a specific embodiment of the hidden electric vehicle charging pile provided in this embodiment, the guide component includes two guide members 40. The inner walls on both sides of the housing 10 are provided with sliding grooves in the vertical direction. The guide members 40 are rigid members. One end of each of the two guide members 40 is connected to the base 22, and the other end is slidably engaged with the two sliding grooves respectively.

[0053] like Figures 1 to 5 As shown, in a specific embodiment of the concealed electric vehicle charging pile provided in this embodiment, the first lifting mechanism includes a support plate 51, a sliding shoe 52, a second screw 53, and a second motor assembly 54. One end of the support plate 51 is hinged to the base 22, and the other end is hinged to the sliding shoe 52. The sliding shoe 52 is disposed on the filter plate 12 and slides in cooperation with the filter plate 12. The second motor assembly 54 is connected to the inner wall of the housing 10. One end of the second screw 53 is connected to the power output end of the second motor assembly 54, and the other end is rotatably connected to the inner wall of the housing 10. The second screw 53 passes through the sliding shoe 52 and is threadedly engaged with the sliding shoe 52.

[0054] It should be noted that the second screw 53 is arranged horizontally. When the charging pile mechanism is underground, the two ends of the support plate 51 are far apart in the horizontal direction. When the charging pile mechanism needs to be raised, the second motor assembly 54 drives the second screw 53 to rotate, causing the slipper 52, which is hinged to one end of the support plate 51, to slide to the side where the other end of the support plate 51 is located, thereby raising the charging pile mechanism. When the charging pile mechanism needs to be retracted underground, the second motor assembly 54 drives the second screw 53 to rotate in the opposite direction, causing the slipper 52, which is hinged to one end of the support plate 51, to slide to the side away from the other end of the support plate 51, thereby retracting the charging pile mechanism.

[0055] like Figures 1 to 5As shown, in a specific embodiment of the hidden electric vehicle charging pile provided in this embodiment, the housing 10 is further provided with a second cavity 13. The second cavity 13 is located on one side of the first cavity and communicates with the first cavity. A cleaning component 55 is installed at the bottom of the slipper 52 to sweep the garbage on the filter plate 12 into the second cavity 13.

[0056] It should be noted that the two ends of the slipper 52 abut against the inner walls of both sides of the housing 10, and the cleaning component 55 is a cleaning brush installed at the bottom of the slipper 52 or a cleaning cloth wrapped around the bottom of the slipper 52.

[0057] like Figure 1 and Figure 6 As shown, in a specific embodiment of the concealed electric vehicle charging pile provided in this example, a collection box 61 and a negative pressure pump 62 are also included. The housing 10 is further provided with a third cavity 14, a fourth cavity, a fifth cavity, and a negative pressure pipe 15. The third cavity 14 is located on one side of the second cavity 13, and the opening of the third cavity 14 faces the second cavity 13. The bottom of the second cavity 13 is inclined to the third cavity 14, so that the garbage in the second cavity 13 can freely slide into the third cavity 14. The fourth cavity is located on the upper side of the second cavity 13, and the collection box 61 is placed inside. One end of the negative pressure pipe 15 is connected to the third cavity 14, and the other end is connected to the air inlet of the collection box 61. The fifth cavity is located on one side of the fourth cavity, and the negative pressure pump 62 is located in the fifth cavity. The negative pressure port of the negative pressure pump 62 is connected to the air outlet of the collection box 61, and the exhaust port of the negative pressure pump 62 is connected to the first cavity.

[0058] It should be noted that the filter plate 12 is a plate with several small holes. If the garbage that falls on the filter plate 12 is not cleaned for a long time, it will accumulate on the filter plate 12 and eventually clog it, causing water to accumulate in the first cavity and damaging the charging pile body 23 due to moisture. By installing the cleaning component 55 at the bottom of the sliding shoe 52, the garbage on the filter plate 12 can be pushed into the second cavity 13 as the charging pile mechanism descends and retracts. The garbage in the second cavity 13 then slides into the third cavity 14, where the garbage is collected. The negative pressure pump 62 creates negative pressure in the negative pressure pipe 15, and the garbage is sucked into the collection box 61 through the negative pressure pipe 15. The staff will periodically remove the collection box 61 and empty the garbage in the collection box 61, thereby effectively preventing the filter plate 12 from being clogged, keeping the first cavity dry for a long time, and extending the service life of the charging pile.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
