Description
Technical Field
[0001] The utility model relates to the technical field of charging piles, in particular to a charging pile with a cable pulling and breaking prevention mechanism. Background Art
[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall, installed in public buildings and parking lots or charging stations in residential areas, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, and charging time.
[0003] The main body of the charging pile is connected to the charging gun through a cable, and the car owner charges by inserting the charging gun into the vehicle. Users of private charging piles may be more careful. On the one hand, it will be gentler when pulling the charging gun. On the other hand, private parking spaces will only park the owner's vehicles, so the reserved length of the cable will be sufficient for use. However, there will be the following problems for charging piles in public parking spaces. The dedicated charging parking space may be occupied by a refueling truck, and new energy vehicles can only be parked in adjacent parking spaces. At this time, new energy vehicles will use the adjacent charging pile for charging, and sometimes the cable is not long enough. The car owner may pull the charging gun of the adjacent charging pile for charging, or even damage the cable and the charging connection due to improper operation. Therefore, there is a problem of the cable being pulled and damaged from the main body of the charging pile. Utility Model Content

After the outsider releases the pull on the charging cable 3, the elastic reset of multiple springs 8 and elastic members 15 drives the protrusion 22 to disengage from the contact switch 6, so that the warning light 5 and the alarm 4 no longer work, thereby preventing people from violently pulling the charging cable 3 during use, reducing the probability of damage to the charging cable 3, and improving the protection effect of the charging cable 3.
[0037] After the outside personnel charge the car, if they deliberately discard the charging head at a position far away from the charging pile body 1, the two groups of third sliding blocks 26 can be controlled to drive the two baffles 21 inside the corresponding third sliding groove 20 to block the through hole 17, and then the double-headed screw 24 can be controlled to drive the two second clamping blocks 19 to clamp and fix the charging line 3, and the telescopic ends of the two second electric telescopic rods 12 can be controlled to extend together, so that the baffle 21 can be pushed and the movable plate 7 can be driven to move in the direction close to the charging pile body 1 inside the box body 2, and the charging line 3 exposed outside the box body 2 can be pulled back toward the inside of the box body 2 for a section. After repeating the above operation many times, the charging head can be pulled to a position close to the charging pile body 1, so as to avoid the problem that the charging head is located far away from the charging pile body 1 and cannot be protected by the shielding shed above the charging pile body 1, resulting in the problem that the charging head is damaged and cannot be used anymore. This can also have a protective effect on the charging head and improve the practicality of the device.
