[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings, residential parking lots, or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] Most existing charging stations are fixedly installed on the ground, and the charging cables are scattered on the ground. This takes up a lot of space, affects pedestrians, and poses certain safety hazards. In addition, charging stations that are on the ground for a long time are not only subject to rainwater erosion, but also accumulate a lot of dust and impurities on their surface, all of which affect the normal use of the charging stations and the user experience.

[0031] To better understand the above technical solutions, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please see Figure 1 , 4 5, 6, 7, A concealed charging device capable of cleaning the surface of a charging pile includes a base 1, a wedge 2 fixedly connected to the top of the base 1, a charging pile 3 disposed outside the base 1, and a drainage mechanism 5 disposed inside the base 1. The drainage mechanism 5 includes a placement groove 51, a piston 52, a water guide pipe 53, a water tank 54, a one-way valve 55, and a plate 56. The placement groove 51 is disposed inside the base 1, the piston 52 is fixedly connected to the side of the charging pile 3, the water guide pipe 53 is disposed inside the base 1, and the water tank 54 is disposed inside the base 1. A one-way valve 55 is fixedly connected inside the water pipe 53, and a plug plate 56 is fixedly connected to the side of the base 1. A charging pile cleaning mechanism 6 is provided on the outside of the pile body 3. The charging pile cleaning mechanism 6 includes a motor 61, a gear 62, a gear ring 63, a cleaning brush 64, and a roller 65. The motor 61 is fixedly connected inside the base 1, the gear 62 is fixedly connected to the top of the motor 61, the outer side of the gear ring 63 meshes with the gear 62, the cleaning brush 64 is fixedly connected to the inner side of the gear ring 63, and the roller 65 is rotatably connected to the outer side of the gear ring 63.

[0033] The top of pile 3 has a symmetrical inclined surface; this facilitates rainwater to flow down from the top of pile 3.

[0034] The charging pile 3 is located inside the placement groove 51. A piston 52 is slidably connected to the inside of the placement groove 51. A water pipe 53 is connected to the placement groove 51. One side of a water tank 54 is connected to the external environment, and the other side is connected to a sewer. The water tank 54 is connected to the water pipe 53. A one-way valve 55 is installed at the connection between the water tank 54 and the water pipe 53. The water pipe 53 is located between the water tank 54 and the placement groove 51. An insert plate 56 is inserted into the base 1. The tilt angle of the top of the insert plate 56 is the same as the tilt angle of the top surface of the charging pile 3. The insert plate 56 is located between the water pipe 53 and the water tank 54. The placement groove 51 is used to hide the charging pile 3 when it is not in use, thus reducing the ground space occupied by the charging pile. The design of 52 allows water flowing into the placement tank 51 to accumulate at the top of piston 52, so that it can be discharged through water pipe 53 when piston 52 moves upward. This prevents the pile body 3 from being submerged in water for a long time when it is hidden, which could cause the paint on the surface of the pile body 3 to bulge. The inclined surface at the top of the pile body 3 and the inclined surface at the top of the insert plate 56 allow rainwater and dew to flow smoothly into the water tank 54, which greatly prevents rainwater and dew from accumulating and damaging the outer shell of the pile body 3. Furthermore, the one-way valve 55 is designed to allow water from inside the water pipe 53 to enter the water tank 54, thus preventing backflow of water inside the water tank 54. The insert plate 56 can guide the pile body 3 when it moves up and down.

[0035] The charging pile cleaning mechanism 6 is located between the plug plate 56 and the pile body 3. Gear 62 is located inside the base 1, and gear ring 63 is rotatably connected inside the base 1 and outside the pile body 3. The inner side of the cleaning brush 64 contacts the outer surface of the pile body 3, and rollers 65 are rotatably connected inside the base 1. The cleaning brush 64 is made of soft material, and multiple rollers 65 are evenly distributed at the bottom of the gear ring 63. The cleaning brush 64 is designed to clean the surface of the pile head 3 when it moves up and down. When the cleaning brush 64 rotates, it can perform a circumferential cleaning of the surface of the pile body 3. This cleaning method is more efficient, and the soft brush material can reduce damage to the paint surface of the pile body 3. The rollers 65 can reduce the friction generated when the gear ring 63 rotates, and the rollers 65 also have a better guiding effect.

[0036] Please see Figure 1-5 The base 1 is equipped with a charging pile retraction mechanism 4 on its exterior. The charging pile retraction mechanism 4 is located on the exterior of the inclined block 2. The pile body 3 is equipped with a winding mechanism 7 inside its interior. The pile body 3 is equipped with a control module 8 inside its interior.

[0037] The charging pile retraction mechanism 4 includes a slot 41, a rod 42, a spring 43, a carrier plate 44, a buzzer 45, a cylinder 46, an oil plug 47, an oil groove 48, an oil passage 49, hydraulic oil 410, an oil plug 411, a rack 412, a gear 413, a rotating shaft 414, a threaded rod 415, a threaded groove 416, an electro-hydraulic rod 417, and an annular top plate 418. The slot 41 is formed on the surface of the base 1. The rod 42 is slidably connected to the inside of the slot 41. The spring 43 is set on the outside of the rod 42. The carrier plate 44 is fixedly connected to the top of the rod 42. The number of insertion rods 42 is greater than or equal to four and evenly distributed at the bottom of the carrier plate 44. A spring 43 is disposed between the carrier plate 44 and the base 1. The number of slots 41, insertion rods 42, and insertion rods 42 are equal. A buzzer 45 is fixedly connected to the top of the carrier plate 44. A cylinder 46 is fixedly connected to the bottom of the carrier plate 44. An oil plug 47 is fixedly connected to the bottom of the cylinder 46. An oil groove 48 is disposed inside the base 1. The oil plug 47 is slidably connected to the inner side of the oil groove 48. The cylinder 46 is slidably connected to the base 1. An oil passage 49 is disposed inside the base 1. One end of 9 is connected to the bottom of the oil tank 48. Oil plug 2 411 is slidably connected to the inside of the oil passage 49. The space enclosed by the outside of oil plug 2 411, the inside of the oil passage 49, the inside of the oil tank 48, and the bottom of oil plug 1 47 forms a hydraulic chamber. The hydraulic chamber is filled with hydraulic oil 410. A rack 412 is fixedly connected to the side of oil plug 2 411 away from the hydraulic oil 410. The rack 412 is located inside the oil passage 49. Gear 1 413 meshes with the outside of the rack 412. A rotating shaft 414 is fixedly connected to the outside of gear 1 413. The bottom end of 14 is rotatably connected to the inside of the base 1. The top end of the rotating shaft 414 is fixedly connected to a threaded rod 415. The threaded groove 416 is set inside the pile body 3. The threaded rod 415 is threadedly connected to the threaded groove 416. The electric hydraulic rod 417 is set inside the base 1. The number of electric hydraulic rods 417 is greater than or equal to 2 and they are evenly distributed outside the oil groove 48. The annular top plate 418 is fixedly connected to the top of the electric hydraulic rod 417. The annular top plate 418 is set outside the cylinder 46. The inner side of the annular top plate 418 does not contact the outer side of the cylinder 46.The sliding of the insert rod 42 inside the slot 41 prevents lateral displacement of the carrier plate 44 during vertical movement. When the vehicle tires move on the carrier plate 44, the vehicle's own weight causes the carrier plate 44 to move downwards. This movement, transmitted through the cylinder 46, oil plug 47, hydraulic oil 410, and oil plug 411, causes the rack 412 to move. The rotation of the gear 413 then causes the shaft 414 and threaded rod 415 to rotate. The threaded groove 416 then causes the pile 3 to move upwards, achieving the effect of releasing the pile 3, which aligns with actual vehicle parking and allows for the release of the charging pile when the vehicle is parked and its concealment after the vehicle leaves. The guiding function of the insert plate 56 prevents the pile 3 from rotating or shifting during upward movement. The design of the annular top plate 418 ensures that the electric hydraulic rod 417 provides even support to the bottom of the carrier plate 44 when it extends.

[0038] Please see Figure 1 , 4 The winding mechanism 7 includes an electric telescopic plate 71, a sealing strip 72, a control panel 73, a charging gun 74, a charging cable 75, and an electric winding roller 76. The electric telescopic plate 71 is installed on the inner wall of the pile body 3, the sealing strip 72 is installed on the outside of the electric telescopic plate 71, the control panel 73 is fixedly connected to the inside of the pile body 3, the charging gun 74 is inserted into the outside of the pile body 3, one end of the charging cable 75 is fixedly connected to the outside of the charging gun 74, and the other end of the charging cable 75 is fixedly connected to the outside of the electric winding roller 76. The electric winding roller 76 is rotatably connected to the inside of the pile body 3. After the electric telescopic plate 71 extends, the sealing strip 72 can prevent water and dust from contacting the control panel 73 and the charging gun 74 when the pile body 3 is retracted into the placement groove 51. This also makes it easier for the cleaning brush 64 to clean the pile body 3.

[0039] Please see Figure 1-8The control module 8 includes a signal acquisition module 81, a signal processing module 82, a balance sensing module 83, a motion sensing module 84, a plug-in / plug-out sensing module 85, and a pressure sensing module 86. The signal acquisition module 81 collects information from the balance sensing module 83, motion sensing module 84, and plug-in / plug-out sensing module 85. The balance sensing module 83 senses the balance state of the carrier plate 44 in real time. The motion sensing module 84 senses the up-and-down movement of the carrier plate 44 in real time. The plug-in / plug-out sensing module 85 senses the plug-in / plug-out status between the charging gun 74 and the placement port on the pile body 3 in real time. The pressure sensing module 86 senses the unpressurized state of the top of the carrier plate 44 in real time. When a vehicle tire enters the carrier plate 44... When the balance of the carrier plate 44 is disrupted, the balance sensing module 83 sends the imbalance information of the carrier plate 44 to the signal acquisition module 81, which in turn sends the information to the signal processing module 82. The signal processing module 82 then controls the buzzer 45 to be powered on and sound. When the vehicle tire moves to the balance point of the carrier plate 44 or leaves the carrier plate 44, the carrier plate 44 returns to its balanced state. The balance sensing module 83 then sends the balance information of the carrier plate 44 to the signal acquisition module 81, which in turn sends the information to the signal processing module 82. The signal processing module 82 then controls the buzzer 45 to be powered off and stop sounding. When the carrier plate 44 moves downwards, the motion sensing module 84 will detect the movement of the carrier plate 44. The status signal is sent to the signal acquisition module 81, which then sends it to the signal processing module 82. The signal processing module 82 controls the motor 61 to power on and operate, and controls the electric telescopic plate 71 to power on and retract. When the user pulls out the charging gun 74, the insertion / removal sensing module 85 sends the removal information to the signal acquisition module 81, which then sends it to the signal processing module 82. The signal processing module 82 controls the electric take-up roller 76 to operate and release the charging cable 75. When the user inserts the charging gun 74 back into the circuit, the insertion / removal sensing module 85 sends the insertion / removal information to the signal acquisition module 81, which then sends it to the signal processing module 82. 2. Control the operation of the electric winding roller 76 to wind up the charging cable 75 and control the electric hydraulic rod 417 to extend. The extension of the electric hydraulic rod 417 will drive the annular top plate 418 to move upward. The upward movement of the annular top plate 418 will drive the carrier plate 44 to move upward, thereby causing the carrier plate 44 to move upward to the initial position. If the charging gun 74 is not inserted back into the placement port, there will be a height difference between the carrier plate 44 and the inclined block 2. This will prevent the vehicle tires from leaving the carrier plate 44 and thus prevent the vehicle from dragging the charging cable 75 while driving. This will ensure the safety of the charging gun 74, the charging cable 75, the electric winding roller 76, and the pile body 3, and will prevent the charging cable 75 from falling to the ground. It will also allow the vertical movement of the pile body 3 to be unobstructed.When the carrier plate 44 moves upward, the motion sensing module 84 sends the motion status of the carrier plate 44 to the signal acquisition module 81. The signal acquisition module 81 then sends this information to the signal processing module 82, which controls the motor 61 to power on and extend the electric telescopic plate 71. When the carrier plate 44 is not moving, the motion sensing module 84 sends the inactive state of the carrier plate 44 to the signal acquisition module 81. The signal acquisition module 81 then sends this information to the signal processing module 82, which controls the motor 61 to power off and stop running, and controls the electric telescopic plate 71 to power off and maintain its extended / retracted state. When the vehicle tire leaves the top of the carrier plate 44, the pressure sensing module 86 sends the information that the carrier plate 44 is no longer under pressure to the signal acquisition module 81. The signal acquisition module 81 then sends this information to the signal processing module 82, which controls the electric hydraulic rod 417 to power on and retract to its initial state.

[0040] When the invention is in operation, the carrier plate 44 moves downward under the influence of the vehicle's gravity. The movement of the carrier plate 44 causes the insert rod 42 to slide inside the slot 41 and causes the cylinder 46 to move downward. The downward movement of the cylinder 46 causes the first oil plug 47 to move downward. The downward movement of the first oil plug 47 compresses the hydraulic oil 410. The hydraulic oil 410, under pressure, compresses the second oil plug 411. The second oil plug 411 slides under pressure and causes the rack 412 to move. The movement of the rack 412 causes the first gear 413 to rotate. The rotation of the first gear 413 causes the rotating shaft 414 to rotate. The rotation of the rotating shaft 414 causes the threaded rod 415 to rotate. The rotation of the threaded rod 415, under the action of the threaded groove 416, causes the pile body 3 to move upward. The upward movement of the pile body 3 causes the insert plate 56 to move upward. At the same time, the motor 61 is powered on and starts to drive the second gear 62 to rotate. The rotation of the second gear 62, under the rolling action of the roller 65, drives the gear ring 63 to rotate. The rotation of the gear ring 63 drives the cleaning brush 64 to rotate.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
