Specific Embodiments

[0011] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0012] An electric vehicle charging pile, such as Figures 1-3As shown in the figure, it includes a charging pile body and a protection box 1. A fixing block is fixedly installed at the top end of the support rod of the charging pile body. A screw hole is opened on one side of the fixing block. A U-shaped protection plate 10 is installed above the charging pile body in a matching manner. 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 rod with a motor is movably installed between the two support plates. The screw rod passes through the screw hole. Several universal wheels are fixedly installed at the bottom end of the protection box 1. A partition 2 is fixedly installed in the protection box 1. Through holes are opened in the middle of one side of the protection box 1 and one side of the partition 2. The partition 2 divides the protection box 1 into two cavities. An automatic wire rewinder is fixedly installed in one of the cavities. The cable of the charging pile body passes through the automatic wire rewinder. An opening is opened on the other side of the protection box 1. An inclined placement plate 3 is slidably installed on the other side of the protection box 1. A control member is installed on the other side of the protection box 1. The control member can control the up and down lifting of the placement plate 3. Limit plates are fixedly installed at the front and rear ends of the top surface of the placement plate 3. The charging gun head of the charging pile body is placed between the two limit plates. 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 cable reel can be selected as the EV Safe PowerReel 360 electric automatic cable reel. Another side of the protection box 1 is provided with a placement cavity, and a control panel is slidably installed in the placement cavity. The control panel can also control the automatic cable reel. The charging cable of the charging pile body passes through the through hole of the protection box and is wound around the automatic cable reel. 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 vision sensor is installed at the top of another cavity. There is a certain contraction length of the cable between the charging gun head and the automatic cable reel, which is convenient for taking out the charging gun head from the protection box and inserting the charging gun head into the vehicle charging port. When the vehicle stops beside the outdoor charging pile body, through the action of the universal wheels, the protection box 1 is pushed to move, so that the protection box 1 moves beside the vehicle. During the movement, the automatic cable reel pays out the cable for pay-out operation, that is, pulls out the control panel outward, selects the pay-out button of the automatic cable reel, and then takes out the charging gun head from the protection box 1 and inserts the charging gun head into the vehicle charging port. After charging is completed, select the rewind button of the automatic cable reel, and the automatic cable reel winds the cable back into the automatic cable reel again. During this process, if the user does not place the charging gun head on the placement plate but just discards it casually, at this time, the automatic adjustment component controls the movement of the cable, and the control part controls the placement plate to slide up and down. Through cooperation, the charging gun head is recycled onto the placement plate 3, avoiding the charging gun head being randomly discarded on the ground, avoiding damage to the charging gun head, and also avoiding the charging gun head contacting water on the ground, 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. The screw-thread fit of the screw and the screw hole can control the U-shaped plate 10 to move to the right to shield the charging equipment on the charging pile body, avoiding safety accidents caused by rain 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 protection box 1. When the protection box is not in use, the iron sheet is adsorbed by the weak magnetic magnet, so that the U-shaped plate can be connected to the protection box, protect the charging equipment, and also limit the protection box to prevent the protection box from moving around randomly.

[0013] Specifically, the control member described in this embodiment includes two first electric telescopic rods 4. The fixed ends of the two first electric telescopic rods 4 are respectively fixedly installed on the inner walls of the front and rear ends of the protection box 1. The top of the mobile end of the first electric telescopic rod 4 is fixedly connected to the bottom surface of the placement plate 3. The first electric telescopic rod is connected to the controller. After the pressure sensor transmits the signal to the processor, the processor conveys the information to the empty controller, and the controller controls the first electric telescopic rod 4 to extend or contract. When the charging gun head is outside the protection box 1, that is, in the discarded state, for example, when the vision sensor detects that the length of the charging gun head exposed outside is relatively long and transmits the information to the processor, the processor transmits the processed information to the controller, and the controller controls the first electric telescopic rod 4 to extend, pushing the placement plate 3 to move upward. At the same time, the automatic adjustment component also synchronously adjusts the tightness change of the cable between the partition and the gun head, pulling the charging gun head back onto the placement plate 3. Moreover, through the inclined placement plate, it is more convenient for the charging gun head to slide upward from bottom to top, enabling the charging gun head to be retracted onto the placement plate to protect the charging gun head.

[0014] Further, the automatic adjustment component described in this embodiment includes: Two groups of second electric telescopic rod groups 5. The two groups of second electric telescopic rod groups 5 are arranged vertically and staggeredly. Each group of second electric telescopic rod groups 5 consists of two second electric telescopic rods. The two second electric telescopic rods in each group of second electric telescopic rod groups 5 are respectively fixedly installed on the inner walls of the front and rear ends of the protection box 1; Two pressure rods 6. Each pressure rod 6 is fixedly connected to the mobile ends of the two second electric telescopic rods in the same group of second electric telescopic rod groups; A guiding and stabilizing member. The cable passes through the guiding and stabilizing member.

[0015] The extending directions of the two groups of second electric telescopic rods 5 are opposite. The cable is located between the two pressure rods 6. The cable of the charging pile body passes between the two pressure rods 6 and through the guiding and stabilizing member. When it is necessary to retract the charging gun head, the second telescopic rods in the two groups of second electric telescopic rod groups extend under the control of the controller, pushing the two pressure rods 6 to move relatively. During the relative movement of the two pressure rods 6, the tightness of the cable is adjusted, that is, the cable is pulled into the protection box 1, causing the charging gun head to move into the protection box. During the adjustment process of the cable, the guiding and stabilizing member guides the cable to prevent the cable from shifting.

[0016] Still further, the guiding and stabilizing member described in this embodiment includes: Two vertical plates 7. The opposite ends of the two vertical plates 7 are respectively fixedly installed at the upper and lower ends of the protection box 1. Grooves are respectively formed on the opposite surfaces of the two vertical plates 7; Two moving plates 8. The moving plates 8 can be inserted into the grooves. The opposite ends of the two moving plates 8 are respectively movably installed with groove wheels 9; A spring, one end of the moving plate 8 is fixedly connected to one end of the groove through the spring.

[0017] The structure of the groove wheel 9 is as Figure 3 shown. The specific connection relationship among the spring, the moving plate 8 and the groove is as follows: for the moving plate, groove and spring located above, the spring is located between the top end of the moving plate 8 and the inner wall of the top end of the groove and is fixedly connected; for the moving plate, groove and spring located below, the spring is located between the bottom end of the moving plate and the inner wall of the bottom end of the groove and is fixedly connected; the circuit passes through between the two groove wheels 9. Under the action of the spring, the two moving plates 8 are pushed to move relatively, 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, it guides the cable, can prevent the cable from swaying around, and can also prevent the circuit from being twisted, extending the service life of the cable. It includes the following steps: S1: Charging completion signal trigger After the charging pile body detects the completion of charging, it sends a signal to the controller, and the controller starts the retracting mode of the automatic cable retractor; S2: Charging gun head status detection Judge whether the charging gun head is in place through the pressure sensor on the placement plate; If the pressure sensor detects that the gun head has been placed on the placement plate, the automatic cable retractor retracts the cable normally until the end; If the pressure sensor does not detect the gun head, the vision sensor detects the length of the gun head exposed outside the protection box and transmits the signal to the controller; S3: Linkage control of the automatic adjustment component Step A: Adjustment of the placement plate position The controller controls the first electric telescopic rod to extend, pushing the inclined placement plate to move upward to expand the contact range of the gun head retraction entrance; Step B: Cable tension adjustment The controller synchronously controls the action of two groups of second electric telescopic rod groups, driving the two pressure rods to move relatively, clamping and pulling the cable backward to move the gun head into the protection box; Step C: Guide and stability assistance The cable passes through the groove wheel of the guide and stability component during the movement, and the spring pushes the moving plate to clamp the cable with the groove wheel to prevent deviation or distortion; S4: Confirmation of gun head in place When the pressure sensor detects that the gun head has been placed on the placement plate, the controller stops all actions; if it is still not in place, repeat steps A to C until the gun head is recovered.

[0018] Automated recycling: Through the cooperation of sensors and electric telescopic rods, precise recycling of the gun head is achieved, reducing human intervention; Multiple protections: Prevent the gun head from contacting ground moisture or hard objects, extending the equipment life and improving safety; Adaptive adjustment: Automatically adjust the cable tightness and the height of the placement board to meet the recycling requirements of gun heads at different discarding angles.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; And these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
