[0030] See also Figure 1-Figure 6 The present application provides a rail-type electric vehicle charging pile, comprising an I-shaped rail 1, a movable seat 2, a driving mechanism, an adjusting mechanism 3 and a charging pile body 4. Hangers 17 are fixedly installed at both ends of the top of the I-shaped rail 1. Bolt holes are provided on the hanger 17. By setting the hanger 17 and the bolt holes thereon, it is convenient to use bolts to hang and fix the I-shaped rail 1 on the top wall of the underground garage, thereby realizing the suspension use of the charging pile body 4. Compared with the traditional ground installation method, it saves ground space, avoids obstruction to vehicle passage, and also reduces the risk of the charging pile body 4 being damaged by vehicle collision, wherein:

[0031] The moving seat 2 is slidably mounted on the I-shaped guide rail 1, and the driving mechanism is arranged between the I-shaped guide rail 1 and the moving seat 2. The driving mechanism is used to control the horizontal and linear movement of the moving seat 2 on the I-shaped guide rail 1. The driving mechanism includes two racks 7, two driving shafts 8, two lower gears 9, two upper gears 10, a U-shaped frame 11 and a motor 12. The two racks 7 are respectively fixedly mounted on the inner walls of both sides of the I-shaped guide rail 1, and the two driving shafts 8 are rotatably mounted on the top of the moving seat 2, and the two driving shafts 8 are symmetrically arranged on both sides of the I-shaped guide rail 1. The two lower gears 9 are respectively fixedly mounted on the bottom ends of the corresponding drive shafts 8, and the two lower gears 9 are respectively meshed with the corresponding racks 7. The two upper gears 10 are respectively fixedly mounted on the top ends of the corresponding drive shafts 8, and the two upper gears 10 are meshed with each other. The U-shaped frame 11 is fixedly mounted on the top of the moving seat 2, and the motor 12 is fixedly mounted on the top inner wall of the U-shaped frame 11. The output shaft end of the motor 12 is fixedly connected to the top end of one of the drive shafts 8. By utilizing the meshing transmission effect of the two racks 7 and the two lower gears 9, and cooperating with the two upper gears 10 The mutually meshing transmission, when the motor 12 drives one of the driving shafts 8 to rotate, the movable seat 2 can be controlled to move horizontally and linearly on the I-shaped guide rail 1, so that the charging pile body 4 can be flexibly adjusted according to the parking positions of different vehicles, thereby improving the use range of the charging pile body 4. When a fuel vehicle occupies a charging parking space, the charging pile body 4 can also be moved to other parking spaces to charge the electric vehicle, thereby avoiding the situation where the charging pile body 4 is blocked and occupied and cannot be charged. The adjustment mechanism 3 is arranged at the bottom of the movable seat 2, and the charging pile body 4 is arranged at the bottom of the adjustment mechanism. The adjustment mechanism 3 is used to control the horizontal and linear movement of the charging pile body 4. A touch display screen 5 is embedded and fixed on the right side wall of the charging pile body 4, and a charging gun 6 is electrically connected to the right side wall of the charging pile body 4. The touch display screen 5 is used to control the operation of the charging pile body 4, so as to use the charging gun 6 to generate current to charge the electric vehicle. It should be supplemented that the motor 12 adopts a forward and reverse transformation motor, and the motor 12 is electrically connected to the internal power supply of the charging pile body 4. The motor 12 can also be controlled to rotate forward or reverse through the touch display screen 5.

[0032] In this embodiment, two mounting holes are opened on the top of the movable seat 2, and bearings are fixedly mounted on the two driving shafts 8. The outer rings of the two bearings are fixedly installed in the corresponding mounting holes respectively, so as to improve the stability and smoothness of the driving shaft 8 when rotating.

[0033] In this embodiment, T-shaped guide beams 13 are fixedly installed on the top and bottom of the I-shaped guide rail 1, and T-shaped slots 14 are opened on the bottom inner wall and the top inner wall of the moving seat 2. The two T-shaped guide beams 13 slide through the corresponding T-shaped slots 14 respectively. The T-shaped guide beams 13 at the top and bottom of the I-shaped guide rail 1 cooperate with the T-shaped slots 14 on the top and bottom inner walls of the moving seat 2, which plays a good guiding role during the movement of the moving seat 2, prevents it from deflecting or shaking during the movement, and ensures the stability of the movement.

[0034] The second motor 36 is fixedly mounted on the left outer wall of the fixed beam 31, and the output shaft end of the second motor 36 is fixedly connected to the left end of the screw rod 34. By using the second motor 36 to drive the screw rod 34 to rotate, the slide 35 and the charging pile body 4 installed at the bottom thereof can be moved linearly in the horizontal direction, and the position of the charging pile body 4 can be accurately fine-tuned to ensure that the charging gun 6 can be accurately connected to the charging interface of the vehicle. It should be noted that the second motor 36 adopts a forward and reverse transformation motor.

[0035] In this embodiment, a limiting groove 37 is provided on the top inner wall of the slide groove 32, and a limiting block 38 is fixedly installed on the top of the slide seat 35. The limiting block 38 is slidably installed in the limiting groove 37. The limiting groove 37 cooperates with the limiting block 38 on the top of the slide seat 35 to limit the freedom of the slide seat 35 during movement, so that it can only move in a straight line in the horizontal direction, thereby ensuring the stability of the charging pile body 4 during the adjustment process.

[0036] In this embodiment, an infrared ranging sensor 15 is fixedly installed on the right side wall of the charging pile body 4, a controller 16 is fixedly installed on the top of the fixed beam 31, and the motor 2 36, the infrared ranging sensor 15 and the controller 16 are electrically connected. The infrared ranging sensor 15 can be used to monitor the distance between the charging pile body 4 and the electric vehicle to be charged. The controller 16 controls the operation of the motor 2 36 according to the feedback signal of the infrared ranging sensor 15, so as to realize the intelligent adjustment of the position of the charging pile body 4 and improve the convenience and automation of charging. It should be noted that the controller 16 adopts a PLC controller, and the control method of the motor 2 36 is automatically controlled by the controller 16. The control circuit of the controller 16 can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field, so the control method and circuit connection are not explained in detail.

[0037] In this embodiment, a avoidance hole is opened on the left inner wall of the slide groove 32, and the output shaft end of the second motor 36 passes through the avoidance hole, which can ensure that the output shaft of the second motor 36 rotates smoothly.

[0038] In this embodiment, columns 18 are fixedly installed at the four corners of the bottom of the charging pile body 4, and rollers 19 are rotatably installed at the bottom ends of the four columns 18, which can play a role in auxiliary support of the charging pile body 4 and improve the stability of the charging pile body 4 during movement and use. The rollers 19 are in contact with the ground of the underground garage.

[0039] Through the above structure, the working principle of the rail-type electric vehicle charging pile provided by this application is as follows:

[0040] When the position of the charging pile body 4 needs to be adjusted to adapt to different parking spots of electric vehicles, the motor 12 is started to rotate forward or reversely, and the output shaft of the motor 12 drives the drive shaft 8 connected thereto to rotate. Since the two upper gears 10 are meshed with each other, the other drive shaft 8 also rotates synchronously, and the lower gears 9 at the bottom ends of the two drive shafts 8 are respectively meshed with the racks 7 fixed on the inner walls of both sides of the I-shaped guide rail 1. This gear and rack transmission method can convert the rotational motion of the drive shaft 8 into the horizontal linear movement of the moving seat 2 on the I-shaped guide rail 1, and then the moving seat 2 drives the adjustment mechanism 3 and the charging pile body 4 to move horizontally and linearly, so as to realize a large range of position adjustment of the charging pile body 4, and effectively solve the problem that when a fuel vehicle occupies a charging parking space, the charging pile body 4 is blocked and occupied, resulting in the inability to charge;

[0041] When the charging pile body 4 is adjusted to a suitable position at the rear of the electric vehicle to be charged, the infrared distance sensor 15 on the charging pile body 4 will monitor and measure the distance between the charging pile body 4 and the electric vehicle, and transmit the measured distance data to the controller 16. The controller 16 accurately controls the operation of the motor 2 36 according to the feedback signal received from the infrared distance sensor 15. For example, when the distance between the charging pile body 4 and the electric vehicle is greater than the set threshold, the controller 16 controls the motor 2 36 to rotate forward, and the output shaft of the motor 2 36 drives the screw rod 34 to rotate forward. Since the slide 35 is threadedly sleeved on the screw rod 34, the rotation of the screw rod 34 causes the slide 35 to rotate forward. 5 makes horizontal linear motion along the screw rod 34, and the charging pile body 4 installed at the bottom of the slide seat 35 also makes precise horizontal position fine adjustment accordingly, so that the charging pile body 4 gradually moves towards the direction close to the electric vehicle. When the distance between the charging pile body 4 and the electric vehicle gradually decreases to a suitable distance, the controller 16 controls the motor 2 36 to stop running, and then the personnel can unplug the charging gun 6 and smoothly plug it into the charging port of the electric vehicle, and operate the touch display screen 5 to charge the electric vehicle. When the distance between the position where the personnel drive the electric vehicle to park and the charging pile body 4 is far, there is no need to restart the electric vehicle to reverse and adjust the position, which improves the convenience of charging operation;

[0042] When charging is completed, the personnel can insert the charging gun 6 back into the charging pile body 4. At this time, the controller 16 will control the motor 2 36 to reverse and control the charging pile body 4 to gradually move away from the electric vehicle to return to its original position.

[0043] The above is a detailed introduction to a rail-type electric vehicle charging pile provided by the present application. Specific embodiments are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
