DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] A car charging pile, such as Figure 1-3As shown, it includes a charging pile body and a protection box 1. A fixing block is fixedly installed on the top of the support rod of the charging pile body, and a screw hole is opened on one side of the fixing block. A U-shaped protection plate 10 is installed on the top of the charging pile body. Support plates are fixedly installed on both sides of the bottom end of the horizontal plate of the U-shaped protection plate 10. A screw with a motor is movably installed between the two support plates. The screw passes through the screw hole, and several universal wheels are fixedly installed on the bottom end of the protection box 1. A partition 2 is fixedly installed in the protection box 1. Through holes are opened on one side of the protection box 1 and the middle part of one side of the partition 2. The partition 2 divides the protection box 1 into two cavities, one of which is fixedly installed with an automatic wire reel, and the cable of the charging pile body passes through the automatic wire reel. An opening is opened on the other side of the protection box 1, and an inclined placement plate 3 is slidably installed on the other side of the protection box 1. A control component is installed on the other side of the protection box 1, and the control component can control the up and down lifting of the placement plate 3. Limiting plates are fixedly installed on the front and rear ends of the top of the placement plate 3. The charging gun head of the charging pile body is placed between the two limiting plates, and an automatic adjustment component is installed in the other cavity.The charging pile body 1 is an outdoor charging pile, not shown in the figure. The automatic wire retractor can be selected as EV Safe PowerReel 360 electric automatic wire take-up device, a placement cavity is opened on the other side of the protection box 1, and a control panel is slidably installed in the placement cavity. The control panel can also control the automatic wire take-up device. The charging cable of the charging pile body passes through the through hole of the protection box and is wound on the automatic wire take-up device, and the charging gun head is placed on the placement plate 3. A pressure sensor is installed on the top surface of the placement plate 3 to detect whether the charging gun head is placed on the placement plate. A visual sensor is installed on the top of the other cavity. There is a certain contraction length of the cable between the charging gun head and the automatic wire take-up device, which is convenient for taking the charging gun head out of the protection box and inserting the charging gun head into the car charging port. When the car is parked next to the outdoor charging pile body, the protection box 1 is pushed to move by the universal wheel, so that the protection box 1 is moved to the side of the car. During the movement, the automatic wire take-up device pays out the cable, that is, pulls the control panel outward, selects the pay-out button of the automatic wire take-up device, and then takes the charging gun head out of the protection box 1 and inserts the charging gun head into the car charging port. After charging is completed, selects the take-up button of the automatic wire take-up device, and the automatic wire take-up device takes out the cable. The charging gun head is wound into the automatic wire reel again. During this process, if the user does not place the charging gun head on the placement plate and discards it casually, the automatic adjustment component controls the movement of the cable, and the control component controls the placement plate to slide up and down. Through cooperation, the charging gun head is recovered to the placement plate 3, avoiding the charging gun head from being casually discarded on the ground, avoiding damage to the charging gun head, and also avoiding the charging gun head from contacting water on the ground, thereby improving safety; when the rain sensor detects rainy weather, the motor of the screw works under the control of the controller to control the screw to rotate, and the screw cooperates with the thread of the screw hole to control the U-shaped plate 10 to move to the right, shielding the charging equipment on the charging pile body, avoiding rain from causing safety accidents to the charging equipment, and improving safety; an iron sheet can be installed on one side of the U-shaped plate 10, and a weak magnetic magnet is installed on the outer wall of one side of the protective box 1. When the protective box is not in use, the iron sheet is attracted by the weak magnetic magnet, so that the U-shaped plate can be connected to the protective box and the charging equipment is protected. The protective box can also be limited to prevent the protective box from moving around.

[0020] Specifically, the control unit described in this embodiment includes two first electric telescopic rods 4, the fixed ends of which are respectively fixedly mounted on the front and rear inner walls of the protective box 1, and the top ends of the movable ends of the first electric telescopic rods 4 are fixedly connected to the bottom surface of the placement plate 3. The first electric telescopic rods are connected to a controller. After the pressure sensor transmits a signal to the processor, the processor transmits the information to the empty controller, which controls the first electric telescopic rods 4 to extend or retract. When the charging gun tip is outside the protective box 1, i.e., in a discarded state, for example, the visual sensor detects that the exposed length of the charging gun tip is too long and transmits the information to the processor. The processor transmits the processed information to the controller, which controls the first electric telescopic rods 4 to extend, pushing the placement plate 3 upward. At the same time, the automatic adjustment component also adjusts the tension of the cable between the partition and the gun tip, pulling the charging gun tip back onto the placement plate 3. Moreover, the tilted placement plate makes it easier to slide the charging gun tip from bottom to top, retracting it onto the placement plate and protecting it.

[0021] Furthermore, the automatic adjustment component described in this embodiment includes:

[0022] Two groups of second electric telescopic rod groups 5, the two groups of second electric telescopic rod groups 5 are arranged up and down and staggered, each group of second electric telescopic rod groups 5 consists of two second electric telescopic rods, and the two second electric telescopic rods in each group of second electric telescopic rod groups 5 are respectively fixedly mounted on the inner walls of the front and rear ends of the protective box 1;

[0023] Two pressure rods 6, each of the pressure rods 6 is fixedly connected to the movable ends of two second electric telescopic rods in the same second electric telescopic rod group;

[0024] A guide stabilizer is provided, through which the cables pass.

[0025] The extension directions of the two groups of second electric telescopic rods 5 are opposite, and the cables are located between the two pressure rods 6. The cables of the charging pile body pass between the two pressure rods 6 and through the guide stabilizer. When the charging gun head needs to be retracted, the second telescopic rods in the two groups of second electric telescopic rods extend under the control of the controller, pushing the two pressure rods 6 to move relative to each other. During the relative movement, the two pressure rods 6 adjust the tightness of the cable, that is, pull the cable into the protective box 1, so that the charging gun head moves into the protective box. During the adjustment process of the cable, the guide stabilizer guides the cable to prevent the cable from deflecting.

[0026] Furthermore, the guide stabilizer described in this embodiment includes:

[0027] Two vertical plates 7, the opposite ends of the two vertical plates 7 are fixedly mounted on the upper and lower ends of the protection box 1, and the opposite surfaces of the two vertical plates 7 are respectively provided with grooves;

[0028] Two movable plates 8, the movable plates 8 can be inserted into the grooves, and groove wheels 9 are movably mounted on opposite ends of the two movable plates 8;

[0029] Spring, one end of the movable plate 8 is fixedly connected to one end of the groove via a spring.

[0030] The structure of the groove wheel 9 is as follows Figure 3 As shown, the specific connection relationship between the spring, movable plate 8 and groove is as follows: the relationship between the movable plate, groove and spring located at the top is that the spring is located between the top of the movable plate 8 and the inner wall of the top of the groove, and is fixedly connected; the relationship between the movable plate, groove and spring located at the bottom is that the spring is located between the bottom of the movable plate and the inner wall of the bottom of the groove, and is fixedly connected; the line passes between the two groove wheels 9, and the action of the spring pushes the two movable plates 8 to move relative to each other, so that the two groove wheels 9 are in contact, and the cable is located in the groove between the two groove wheels 9. During the charging process or the process of retracting the charging gun head, the cable is guided, and the cable can be prevented from shaking around, and the line can be prevented from twisting, thereby extending the service life of the cable. The following steps are included:

[0031] S1: Charging completion signal trigger

[0032] When the charging pile detects that charging is complete, it sends a signal to the controller, which activates the automatic cable reel mode.

[0033] S2: Charging gun head status detection

[0034] Use the pressure sensor on the placement board to determine whether the charging gun head is in place;

[0035] If the pressure sensor detects that the gun tip has been placed on the placement plate, the automatic wire take-up device will reel in the wire normally until the end;

[0036] If the pressure sensor does not detect the gun tip, the visual sensor detects the length of the gun tip exposed outside the protective box and transmits the signal to the controller;

[0037] S3: Automatic adjustment component linkage control

[0038] Step A: Placement board position adjustment

[0039] The controller controls the first electric telescopic rod to extend, pushing the inclined placement plate to move downward, thereby expanding the contact range of the gun head recovery entrance;

[0040] Step B: Cable Tension Adjustment

[0041] The controller synchronously controls the movement of the two second electric telescopic rod groups, driving the two pressure rods to move relative to each other, clamping and pulling the cables backward, so that the gun head moves into the protective box;

[0042] Step C: Steering Stability Assist

[0043] The cable passes through the groove wheel of the guide stabilizer during movement, and the spring pushes the moving plate to make the groove wheel clamp the cable to prevent deviation or twisting;

[0044] S4: Confirmation of gun tip return

[0045] When the pressure sensor detects that the gun tip has been placed on the placement plate, the controller stops all actions; if it still has not returned to its original position, repeat steps A to C until the gun tip is recovered.

[0046] Automated recovery: Through the cooperation of sensors and electric telescopic rods, the gun tip can be accurately recovered, reducing human intervention; Multiple protections: Prevent the gun tip from contacting moisture or hard objects on the ground, extending the life of the equipment and improving safety; Adaptive adjustment: Automatically adjust the cable tightness and placement plate height to adapt to the recovery needs of gun tips at different discarding angles.
