DETAILED DESCRIPTION

[0027] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-Figure 10As shown, an intelligent flexible charging distribution charging pile system includes a distribution cabinet 1, an electric control system, a sensor system, an identification system, a support frame 5, a charging pile 6, a self-propelled mechanism, and a guide rail 8. The distribution cabinet 1 is provided with an electric control system, and the electric control system is externally connected to a power supply. The electric control system is a known prior art, such as the part mentioned in the background technology, and then supplemented by a single-chip microcomputer, an industrial computer or a PLC. The support frame 5 is connected to a plurality of charging piles 6 by sliding left and right from top to bottom in sequence, and each of the charging piles 6 is respectively equipped with a self-propelled mechanism. The support frame 5 is fixed with a plurality of groups of horizontal guide rails 8 in sequence from top to bottom, and each of the self-propelled mechanisms cooperates with each group of guide rails 8 to drive each charging pile 6 to move left and right along the guide rails 8. The charging pile 6 is equipped with a sensor system, and the sensor system is used to measure the left and right position of the support frame 5 relative to the charging pile 6. The sensor system is a known prior art and can be measured by a variety of sensors. Implementation, such as infrared ranging sensors, grating displacement sensors, etc., the identification system includes a door access identification system, a payment identification system and an obstacle identification system, a protection box 9 is fixed to the left part of the support frame 5, each of the charging piles 6 can be moved into the protection box 9 respectively, and each of the protection boxes 9 is respectively installed with a charging cable 10, one end of the charging cable 10 is electrically connected and fixed with a charging gun 11, and the other end is in a surplus state and electrically connected to the electronic control system, each of the charging piles 6 is respectively installed with a left and right bidirectional telescopic mechanism, the left and right parts of the telescopic mechanism are respectively fixed with a projection lamp 13 and an obstacle identification sensor 14 electrically connected to the electronic control system, the obstacle identification system includes a projection lamp 13 and an obstacle identification sensor 14, the projection lamp 13 can project light forward and downward and form a line extending along the front-to-back direction on the obstruction, and the obstacle identification sensor 14 is used to identify whether there is an object blocking the front and downward.

[0029] When in use, the distribution cabinet 1 and the protection box 9 are located outside the parking space. The vehicle information is sensed and released by the access control recognition system, and the length, width and height of the vehicle can be obtained (a recognition camera can be set at the entrance and exit of the parking lot to recognize the license plate of the vehicle, and then the vehicle size information can be obtained in the vehicle management system of the traffic control department, and the gate can be used to control whether the vehicle passes), and the vehicle is allowed to enter the parking lot. Then the self-propelled mechanism and the telescopic mechanism are activated to move the charging pile 6 out of the protection box 9, and the left and right positions of the charging pile 6 relative to the support frame 5 are known by the sensor system. The distance between the projection lights 13 and the obstacle recognition sensor 14 on both sides is controlled by the telescopic mechanism, that is, the light and shadow lines projected on the ground by the projection lights 13 on both sides are used to divide the parking space, and then the obstacle recognition sensor 14 is used to identify the vehicle position, so as to determine whether the vehicle is parked in the divided parking space (an infrared ranging sensor can be used to measure the distance forward. When there is a vehicle obstruction, the measured data is significantly smaller than the normal value, which indicates that the parking is not standardized, otherwise it is standardized). If the vehicle is not parked, normal charging service cannot be performed, thereby driving the driver to park in a standardized manner, so that the parking space is fully and reasonably used. When the parking is qualified, the charging gun 11 can be used manually for charging, and the fee is charged through the payment identification system. After charging is completed, it is determined whether the payment is successful. When the payment is successful, the self-propelled mechanism controls the charging pile 6 to move and reset it to the protective box 9. If the payment is unsuccessful, the access control identification system will not release the vehicle.

[0030] A drag chain cable is installed between the left part of the support frame 5 and each charging pile 6. The left part of the drag chain of the drag chain cable is fixed to the left part of the support frame 5, and the right part of the drag chain of the drag chain cable is fixed to the rear part of the charging pile 6. A terminal socket 16 is fixed to the rear part of each charging pile 6. The part outside the charging pile 6 is electrically and fixedly connected to the right end part of the drag chain cable, and the part inside the charging pile 6 is electrically and fixedly connected to the charging line 10. The left end part of the drag chain cable is electrically connected to the distribution cabinet 1, and a storage mechanism for storing the charging line 10 is installed in the charging pile 6.

[0031] The use of a drag chain cable can protect the charging pile 6 when it moves left and right, thereby reducing cable damage caused by the frequent movement of the charging pile 6. The charging line 10 can be stored through the storage mechanism to reduce disorder and reduce interference with the left and right movement of the charging pile 6.

[0032] The storage mechanism includes a No. 1 servo motor 18, a bidirectional screw rod 19, a left sliding seat 20, a right sliding seat 21, a No. 1 fixed pulley 22, a No. 2 fixed pulley 23, a No. 1 rear wire groove 24, a No. 1 front wire groove 25, a No. 3 fixed pulley 26, a No. 3 rear wire groove 27, a No. 3 front wire groove 28, a threading hole 29, and a control button 62. A No. 1 servo motor 18 is fixed vertically in the charging pile 6, and a horizontal servo motor 18 is connected to the charging pile 6 along the left and right horizontal directions. The bidirectional screw 19, the shaft of the first servo motor 18 is coaxially fixed with a worm, the middle of the bidirectional screw 19 is coaxially fixed with a worm wheel, the shaft of the first servo motor 18 and the bidirectional screw 19 are connected by the meshing of the worm and the worm wheel to achieve transmission connection, the left part of the bidirectional screw 19 is threadedly connected with a left sliding seat 20, and the right part is threadedly connected with a right sliding seat 21, the left sliding seat 20 and the right sliding seat 21 are respectively connected to the charging pile 6 for left and right sliding, the The left upper part of the left sliding seat 20 is rotatably connected to a No. 1 fixed pulley 22, and the bottom is rotatably connected to a No. 2 fixed pulley 23, the No. 1 fixed pulley 22 is provided with a coaxial No. 1 rear wire groove 24 and a No. 1 front wire groove 25 in sequence from back to front, the middle and lower part of the right sliding seat 21 is rotatably connected to a No. 3 fixed pulley 26, the No. 3 fixed pulley 26 is provided with a coaxial No. 3 rear wire groove 27 and a No. 3 front wire groove 28 in sequence from back to front, and the right part of the charging pile 6 is penetrated by threading holes on the left and right sides. 29, after the charging cable 10 is fixedly connected to the wiring seat 16, it passes through the No. 1 rear wire groove 24 and then is wound around the No. 3 rear wire groove 27, then passes through the No. 2 fixed pulley 23 and is wound around the No. 3 front wire groove 28, and then passes through the No. 1 front wire groove 25 and then passes out from the threading hole 29. A control button 62 is provided on the charging gun 11, and the No. 1 servo motor 18 and the control button 62 are electrically connected to the electric control system. The control button 62 is used to control the forward and reverse rotation of the No. 1 servo motor 18.

[0033] Furthermore, when the charging pile 6 is moved out of the protective box 9, the charging gun 11 is held and the control button 62 is pressed, so that the No. 1 servo motor 18 rotates forward. At this time, the left sliding seat 20 and the right sliding seat 21 can be driven to slide close to each other through the bidirectional screw 19, thereby reducing the pulling of the No. 1 fixed pulley 22, the No. 2 fixed pulley 23 and the No. 3 fixed pulley 26 on the charging line 10. Then, the charging line 10 can be manually pulled for charging. After charging is completed, the control button 62 is pressed again to reverse the No. 1 servo motor 18, thereby making the left sliding seat 20 and the right sliding seat 21 move away from each other, and then the No. 1 fixed pulley 22, the No. 2 fixed pulley 23 and the No. 3 fixed pulley 26 can strengthen the pulling of the charging line 10, that is, the charging line 10 is stored, thereby reducing the disorder of the charging line 10. The control button 62 is continuously pressed, that is, the No. 1 servo motor 18 continues to rotate. If it is not pressed, it will not rotate.

[0034] The charging pile 6 is also equipped with a cleaning mechanism, which includes a support plate 30, bristles 31, and a contact roller 32. The threading hole 29 is circular and is coaxially rotatably connected to the support plate 30. The support plate 30 is circular and penetrates left and right, and the inner wall penetrated is coaxially fixed with annular bristles 31. The left part of the inner wall penetrated by the support plate 30 is coaxially fixed with a ring-shaped contact roller 32, each of which can roll and rub against the outer wall of the insulating layer of the charging cable 10. The right part of the bidirectional lead screw 19 penetrates the right part of the charging pile 6, and the bidirectional lead screw 19 and the support plate 30 are connected by gear transmission, belt transmission or chain transmission.

[0035] Furthermore, the No. 1 servo motor 18 can also drive the support plate 30 to rotate through the bidirectional screw 19 when rotating forward and reverse, so as to clean the surface of the charging cable 10 when storing the charging cable 10, thereby reducing the dust on the surface of the charging cable 10 from entering the charging pile 6.

[0036] The cleaning mechanism also includes a vent 33, a filter 34, and a turbofan 35. The bottom of the charging pile 6 is penetrated by a vent 33, and the vent 33 is closed and fixed with a filter 34. The bottom of the rotating shaft of the servo motor 18 is coaxially fixed with the turbofan 35, and the turbofan 35 is aligned with the vent 33 up and down.

[0037] Furthermore, when the No. 1 servo motor 18 rotates forward and reversely, it can drive the No. 1 turbofan 35 to rotate forward and reverse. When the charging cable 10 is stored, the rotating No. 1 turbofan 35 can draw external air through the filter 34 and then discharge it from the support plate 30, thereby improving the cleaning effect of dust on the cable surface.

[0038] The payment identification system includes a human-machine interaction panel 36, and a human-machine interaction panel 36 is installed in front of each charging pile 6. The bottom of the charging pile 6 is rotatably connected to a No. 2 support shaft 37, and a No. 3 support shaft 38 is fixed to each of the left and right ends. The No. 2 support shaft 37 is parallel to the No. 3 support shaft 38. The left and right parts of each No. 2 support shaft 37 are radially fixed with a lower support arm 39, and each No. 3 support shaft 38 is rotatably connected to an upper support arm 40. The front part of the lower support arm 39 and the front part of the upper support arm 40 are respectively hinged to the human-machine interaction panel 36 up and down. The charging pile 6, the second support shaft 37, the third support shaft 38, the lower support arm 39, the upper support arm 40 and the human-machine interaction panel 36 together constitute a parallelogram linkage mechanism, a vertical No. 2 servo motor 41 is fixed in the charging pile 6, a worm is coaxially fixed to the rotating shaft of the No. 2 servo motor 41, a worm wheel is coaxially fixed to the No. 2 support shaft 37, a transmission connection is achieved between the No. 2 support shaft 37 and the rotating shaft of the No. 2 servo motor 41 through the meshing of the worm and the worm wheel, the human-machine interaction panel 36 and the No. 2 servo motor 41 are electrically connected to the electronic control system.

[0039] Furthermore, in actual use, the height of the guide rail 8 from the ground can be set higher, which can reduce the probability of the electric vehicle directly colliding with the charging pile 6. Correspondingly, due to the increase in the height of the charging pile 6, it may be inconvenient for the charger to use it. At this time, the No. 2 servo motor 41 is controlled to rotate forward and reverse through the human-machine interaction panel 36, and the parallelogram linkage mechanism can be used to lift the human-machine interaction panel 36. Specifically, during charging, the human-machine interaction panel 36 can be manually controlled to descend, and after charging is completed, the human-machine interaction panel 36 can be automatically controlled to rise, and then the self-propelled mechanism will act again to return the charging pile 6 to the protection box 9, thereby improving the protection effect.

The telescopic mechanism includes a dual-axis motor 63, a screw 64, a sliding arm 65, an adjusting disk 66, an adjusting slot 67, and a fastening bolt 68.

[0041] Furthermore, by controlling the No. 3 servo motor 45 to rotate forward and reverse, the two right wheel axles 43 can be made to rotate forward and reverse, thereby using the track wheel 44 to move the charging pile 6 left and right, and by controlling the dual-axis motor 63 to rotate forward and reverse, the cooperation between the screw rod 64 and the sliding arm 65 can be used to move the sliding arms 65 left and right, thereby adjusting the left and right distance of the adjustment disk 66 on which the two sliding arms 65 are installed, so that the spacing of the lines projected by the projection lamp 13 on the ground matches the width of different vehicle models, and by rotating the fastening bolt 68 and clamping it at different positions of the adjustment disk 66, the coverage range of the projection lamp 13 and the obstacle recognition sensor 14 can be adjusted to meet different needs.

[0042] Two vertical No. 4 servo motors 46 are fixed on the upper part of the protection box 9, and the rotating shafts of the two No. 4 servo motors 46 are coaxially fixed with No. 4 screw rods 47, and the bottoms of the two No. 4 screw rods 47 are rotatably connected to the protection box 9 respectively.

One of the transmission cylinders 52 is connected to the main brush roller 50 through a transmission mechanism, so that the main brush roller 50 is driven to rotate when the transmission cylinder 52 rotates. The fourth servo motor 46 is electrically connected to the electronic control system.

[0043] Furthermore, when the charging pile 6 returns to the protective box 9, the electronic control system automatically controls the No. 4 servo motor 46 to rotate forward. At this time, the lifting frame 49 can be lowered with the cooperation of the No. 4 screw rod 47 and the lifting frame 49. During the descent, the main brush roller 50 and the auxiliary brush roller 51 are driven to rotate through the transmission cylinder 52, the bevel gear and the transmission mechanism, so as to clean the human-machine interaction panel 36, the projection light 13 and the obstacle recognition sensor 14, so that they can work for a long time. When the lifting frame 49 descends to the bottom of the protective box 9, it stops. After the charging pile 6 is moved out of the protective box 9, the No. 4 servo motor 46 is controlled to reverse, so that the lifting frame 49 moves up and resets.

[0045] Furthermore, when the fourth screw 47 rotates, the transmission plate 56 can be driven to rotate through the bevel gear, thereby driving the main brush roller 50 to rotate, and then driving the push arm 54 and the roller 55 to move circumferentially, thereby rolling and rubbing with the protrusion 58, and then utilizing the elastic repulsive force of the compression spring 57 to make the main brush roller 50 move back and forth left and right, thereby improving the cleaning effect of the human-machine interaction panel 36, that is, improving the protective effect.

[0047] Furthermore, when the No. 4 servo motor 46 rotates forward, the lifting frame 49 descends, and at the same time can drive the shaft turbofan 61 to rotate forward, thereby extracting the air in the protective box 9 and discharging it through the air duct 59, so that the dust generated by the cleaning of the main brush roller 50 and the auxiliary brush roller 51 can be sucked out, reducing the adverse interference caused by the accumulation in the protective box 9 and improving the protection effect.

[0048] The above is a preferred embodiment of the present invention.
