Description

Technical Field

[0001] The utility model relates to the technical field of automobile charging cables, in particular to an electric vehicle charging cable. Background Art

[0002] In the prior art, there are two usage modes for electric vehicle charging cables: one is to place them on the car and use them in different environments with the car; the other is to be placed on charging poles in places such as roads, shopping malls, parking lots, hotels, and garages.

[0003] In the prior art, charging cables are placed on charging poles in public places such as roads, shopping malls, parking lots, hotels, and garages. Due to their public use, they are often pulled and pulled vigorously. Although there is a reinforcement structure at the connection between the cable and the charging gun, the charging cable is stretched due to careless or sudden pulling by multiple users over a long period of time. Since there is no buffer structure at the connection between the cable and the charging gun in the prior art, the connection between the cable and the charging gun is easily damaged over a long period of time. Therefore, an improved electric vehicle charging cable is needed to address this problem. Utility Model Content

[0004] The purpose of the utility model is to provide an electric vehicle charging cable to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric vehicle charging cable, applied to a charging pile, a charging cable is fixedly arranged at the lower end of the charging pile, a charging gun is fixedly arranged at one end of the charging cable, a buffer mechanism for protecting the connection between the charging cable and the charging gun is arranged on the outer surface of the charging cable, the buffer mechanism includes a buffer section, a fixing ring, an extension block, a connecting hole, and a connecting rope, a buffer section is arranged between the charging cable and the charging gun, it should be noted that the buffer section is also a part of the charging cable, that is, an ordinary charging cable is only for determining the installation position of the fixing ring, and the connecting position of the charging cable and the charging gun is called the buffer section, a fixing ring is arranged at the upper and lower ends of the outer surface of the buffer section, an extension block is fixedly arranged on the outer surface of the fixing ring, a connecting hole is opened on the outer surface of the extension block, and a connecting rope is fixedly arranged between the connecting holes.

[0006] Preferably, the fixing ring is a semicircular ring, four of which are provided and wrapped around the outer surface of the buffer section in groups of two; the fixing ring of the semicircular ring can be disassembled and assembled at any time when needed, and the fixing ring can be separated or fixed from the buffer section.

[0007] Preferably, a mounting hole is opened on the surface of the connection hole, and a locking bolt is arranged inside the mounting hole. The locking bolt is inserted into the mounting hole and then tightened, so that the two fixing rings can be tightly clamped and fixed on the outer surface of the buffer section in cooperation with the extension block.

[0008] Preferably, the connecting rope is made of elastic rubber material. When the charging cable is about to be pulled to the limit, the connecting rope made of elastic rubber material can be stretched by utilizing its own elasticity so that the bent buffer section can be straightened. This will have a certain buffering effect to protect the connection between the charging cable and the charging gun. When the pulling disappears, the elastic connecting rope can automatically shrink and recover, driving the buffer end to bend and reset. When the charging cable is about to be pulled to the limit, continuing to pull the elastic connecting rope can provide a certain damping feeling, reminding the user that the charging cable is about to be stretched to the limit. This allows the user to discover it in time and avoids accidentally pulling the charging cable.

[0009] Preferably, soft pads are fixedly provided on both sides of the surface of the fixing ring, and the soft pads can protect the connection between the fixing ring and the charging cable.

[0010] Preferably, a rubber pad is provided on the inner side wall of the fixing ring, and the rubber pad can increase the friction of the inner side wall of the fixing ring, thereby preventing the fixing ring from sliding after the fixing ring is fixed to the outer surface of the charging cable.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the charging cable is about to be pulled to the limit, the utility model can stretch by utilizing its own elasticity so that the bent buffer section can be straightened, which has a certain buffering effect to protect the connection between the charging cable and the charging gun. When the pulling disappears, the elastic connecting rope can automatically shrink and recover, driving the buffer end to bend and reset; and when the charging cable is about to be pulled to the limit, continuing to pull the elastic connecting rope can have a certain damping feeling, reminding the user that the charging cable is about to be stretched to the limit; so that the user can find it in time and avoid the situation of accidentally pulling the charging cable.

[0013] 2. The entire device of the utility model is easy to use, requires little structural change to the charging cable in the prior art, and has low cost, so it can be easily promoted and used. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The surface of the connecting hole 7 is provided with a mounting hole 9, and a locking bolt 10 is arranged inside the mounting hole 9. The locking bolt 10 is inserted into the mounting hole 9 and then tightened, so that the two fixing rings 5 ​​can be tightly clamped and fixed on the outer surface of the buffer section 4 in cooperation with the extension block 6;

[0022] The connecting rope 8 is made of elastic rubber material. When the charging cable 2 is about to be pulled to the limit, the connecting rope 8 made of elastic rubber material can be stretched by its own elasticity so that the bent buffer section 4 can be straightened, which has a certain buffering effect to protect the connection between the charging cable 2 and the charging gun 3.

[0025] Working principle: When using this device, the charging pile 1, the charging cable 2 and the charging gun 3 are used in the same manner as in the prior art. When the user pulls the charging gun 3 to charge the vehicle, the charging port may be far away from the charging pile 1 due to irregular parking and other reasons. As the user pulls the charging cable 2, it will be stretched to the limit distance. At this time, if the user does not pay attention and continues to walk until the charging cable 2 is completely straightened, it will be suddenly straightened. At this time, the device can use the connecting rope 8 of elastic rubber material to stretch the curved buffer section 4 when the charging cable 2 is about to be pulled to the limit by its own elasticity. This will have a certain buffering effect to protect the connection between the charging cable 2 and the charging gun 3. When the pulling disappears, the elastic connecting rope 8 can automatically shrink and recover, driving the buffer end to bend and reset; and when the charging cable 2 is about to be pulled to the limit, continuing to pull the elastic connecting rope 8 can have a certain damping sense, reminding the user that the charging cable 2 is about to be stretched to the limit; so that the user can find it in time and avoid the situation of accidentally pulling the charging cable 2.
