Description
Technical Field
[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile with anti-collision wire collection protection for a new energy vehicle. Background Art
[0002] As new energy vehicles become increasingly popular, the safety and functionality of charging piles, as important supporting infrastructure, are particularly important. However, in practical applications, charging piles face many challenges.
[0003] First, charging piles are often installed close to the road and are vulnerable to accidental collisions with vehicles. Traditional charging pile designs often lack adequate anti-collision protection. Once a collision occurs, it may not only damage the charging pile itself, but also cause harm to vehicles and personnel. Therefore, how to improve the anti-collision ability of charging piles has become an urgent problem to be solved.
[0004] Secondly, during the use of the charging pile, the management of the charging cable is also a key link. If the cable is not managed properly, it will not only affect the charging efficiency, but may also cause damage to the device. For example, a loose cable may lead to poor charging contact, while a tight cable may damage the cable or the device. Therefore, how to achieve accurate retraction of the charging cable and keep the cable tension constant has become another important issue in the design of charging piles.
[0005] In addition, during the use of the charging pile, various pollutants such as dust and moisture are easily attached to the surface of the charging cable. If these pollutants are not removed in time, they will not only affect the charging efficiency, but may also cause corrosion and damage to the charging cable. Therefore, how to design an effective cleaning mechanism to ensure the cleanliness and dryness of the charging cable is also a problem that needs to be solved in the design of the charging pile. Summary of the invention
[0006] The present invention relates to a charging pile with anti-collision wire collection protection for new energy vehicles, so as to solve the problem that the traditional charging pile design has obvious deficiencies in anti-collision protection, cable management and cleaning mechanism.

[0008] Optionally, a buffer core tube made of square tubes connected in sequence vertically is arranged in the protective sleeve, and a communication cavity penetrating through the front and back is arranged on the protective sleeve at the upper end of the buffer core tube.
[0009] Optionally, a servo motor is fixedly installed at one end of the driving frame, a driving rod is rotatably installed on the driving frame, the driving rod is driven by the servo motor, and a first screw thread and a second screw thread are respectively arranged at both ends of the driving rod.

[0013] Optionally, the left and right ends of the guide frame are respectively connected to the side walls of the inner cavity of the charging pile by a third buffer rod, and a third spring is mounted on the third buffer rod to provide the guide frame with a thrust toward the wire harness outlet. A guide roller seat is provided in the middle of the guide frame, and four wire clamping wheels are distributed in a matrix on the guide roller seat. The charging wire passes through the wire clamping wheels, and linkage arms are symmetrically provided on the left and right ends of the guide roller seat close to the wire harness outlet, and the linkage arms are provided with inclined guide holes that pass through the upper and lower parts.
[0014] Optionally, the cleaning frame is symmetrically connected with arc-shaped cleaning covers through two mutually parallel insertion rods. When the cleaning covers are matched, the covers wrap the passing charging cable, and cleaning brushes are evenly distributed on the inner concave surface of the cleaning covers. A follow-up lever is vertically provided on the upper end of the cleaning cover, and the follow-up lever passes upward through the guide hole. When the charging cable is pulled outward, the guide frame moves outward along with the cable, and the linkage arm squeezes the follow-up lever through the guide hole to make the two cleaning covers expand outward, and the charging cable passes freely.

[0015] Optionally, a drain pipe is provided at the lower end of the collecting tray for discharging the collected sewage and dirt.
[0016] The present invention provides a charging pile with anti-collision wire collection protection for new energy vehicles, which has the following beneficial effects: First of all, the charging pile adopts a wall-mounted box design, and a protective cover is provided on the outside of the left and right side walls. The buffer core tube with a square tube matrix structure is used inside the protective cover to form a multi-stage energy absorption system. When the vehicle collides sideways, the trapezoidal array of the buffer core tube can deform step by step to disperse the impact force. At the same time, the top connecting cavity serves as a stress release channel to effectively reduce the risk of damage to the box structure. This design significantly improves the anti-collision ability of the charging pile, and can withstand the low-speed collision standard (15km / h) of electric vehicles specified in ISO 17373, providing higher safety and reliability for the charging pile.
[0017] Secondly, the driving frame inside the charging pile is equipped with a high-precision servo motor, which realizes dual power output through a double-helix driving rod. The first power branch is a worm drive composed of the first screw at the front end of the driving rod and the first worm gear on the take-up frame, which drives the wire roller to actively retract the charging wire; the second power branch is a second screw at the end of the driving rod, which drives the wire wheel through the second worm gear to form a cable transmission power source. This dual-power synchronous control system can achieve precise matching of the wire retracting and releasing speeds, ensure that the cable tension is constant within the range of 15-20N, and avoid the problem of reduced charging efficiency or equipment damage caused by loose or over-tight cables.
[0018] In addition, the tensioning bogie and the retracting and releasing wire frame inside the charging pile form a horizontal buffer system through the first buffer rod and the second buffer rod respectively, which can respond to the cable tension changes in real time during the steering and transportation of the charging line, and eliminate the instantaneous tensile impact caused by the movement of the vehicle. The guide frame forms a floating connection with the side wall of the charging pile through the third buffer rod, and with the matrix clamping wheel set and the inclined guide hole of the linkage arm, the axial movement of the guide frame can be converted into the radial movement of the cleaning mechanism, further improving the stability and accuracy of the charging line guidance.
[0019] The cleaning cover on the cleaning rack cooperates with the guide hole of the linkage arm through the follow-up lever, and can automatically open and close when the charging cable is pulled outward and retracted. The cleaning brush forms an interference fit of 0.5-1.2mm with the surface of the charging cable, ensuring that more than 90% of the attachments on the cable surface can be removed each time the cable is retracted. The collection tray adopts a V-shaped guide groove design, the surface is sprayed with a hydrophobic coating, and the drainage pipe has a built-in filter to achieve solid-liquid separation. Liquid pollutants are directly discharged through the drainage pipe, and solid particles are deposited in the tray's detachable dust box, realizing a maintenance-free cleaning cycle (>500 charge and discharge cycles), which greatly reduces the maintenance cost and difficulty of use of the charging pile.
