Description

Technical Field

[0001] The present invention belongs to the technical field of automobile charging, and in particular relates to a charging device for a new energy automobile. 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 and installed in parking lots or charging stations in public buildings and residential areas. It can charge various types of electric vehicles according to different voltage levels.

[0003] When using a charging pile to charge a new energy vehicle, the driver usually holds the charging gun, then removes the charging cable at one end of the charging gun from the pay-off reel, and then inserts the charging gun connected to the charging cable into the new energy vehicle to charge the new energy vehicle. However, when pulling the charging gun and the charging cable to the position of the new energy vehicle that needs to be charged, if the charging cable removed from the pay-off reel is too long, the charging cable will continue to rub against the ground, and the ground usually has dust, sand and other particles. When the cable rubs against the ground, these particles will continue to scratch the outer sheath of the cable, causing the outer sheath to be damaged. Once the outer sheath is damaged, the internal conductor will be exposed, which is easy to cause leakage accidents, which will not only threaten the safety of personnel, but may also damage the charging equipment and vehicles. In addition, after each charging of the new energy vehicle, the driver is required to rewind the charging cable around the pay-off reel.

When the cleaning plate 1222 needs to be replaced, the clamping bolt 1221 is removed from the clamping plate 1220 and the cleaning plate 1222, and the old cleaning plate 1222 is taken out, and then a new cleaning plate 1222 is replaced, and the new cleaning plate 1222 is re-installed and fixed using the clamping bolt 1221.

The second U plate 129 and the cleaning ring 1217 are driven to rotate so that the side walls of the two cleaning rings 1217 face the direction in which the driver pulls the charging cable 3, so that when the driver pulls the charging cable 3, the pulling force of the charging cable 3 is reduced, which is more labor-saving. At the same time, the sixth motor 1211 is controlled to start, the second round rod 1210 is driven to rotate, and the fixing plate 1212 is used to drive the cleaning ring 1217 to rotate, and the inclination angle of the cleaning ring 1217 is adjusted, thereby changing the direction of the charging cable 3 when being pulled, so that the driver can better pull the charging gun 4 and the charging cable 3 to the charging point of the new energy vehicle.

[0036] The operating principle of the present invention is now described as follows:

[0037] In the present invention, when it is necessary to charge the new energy vehicle, firstly, the second motor 114 and the seventh motor 1215 are controlled to start, and the corresponding support rod 113 and the rotating rod 1214 are driven to rotate respectively, so that the support block 115 and the connecting block 1216 drive the corresponding fixing ring 116 and the cleaning ring 1217 to rotate 90 degrees and then stop, and then the charging cable 3 is placed between the two fixing rings 116 and the cleaning ring 1217, and then the second motor 114 and the seventh motor 1215 are controlled to start, so that the fixing ring 116 and the cleaning ring 1217 are restored to their original positions, and the charging cable 3 is installed between the fixing ring 116 and the cleaning ring 1217, and then the driver holds the charging gun 4 and moves to the charging place of the new energy vehicle. In this process, the first electric telescopic rod is controlled 117 is started, so that the traction drum 119 contacts the outer wall of the charging cable 3, and then the third motor 1110 is controlled to start, driving the traction drum 119 to rotate, and the charging cable 3 is continuously pulled out from the pay-off drum 2. At the same time, the first motor 8 is controlled to start, driving the first gear 9 to rotate. During the rotation of the first gear 9, the second gear 10 meshing with the first gear 9 is driven to rotate, thereby driving the fixing ring 116 to rotate, so that the rotation speed of the fixing ring 116 matches the speed at which the traction drum 119 pulls out the charging cable 3, so that the charging cable 3 can be stably pulled out from the pay-off drum 2, and at the same time, the fourth motor 122 is controlled to start, driving the third gear 123 to rotate, so that the third gear 123 drives the fourth gear 124 to rotate, so that the cleaning ring 1217 follows The fixing ring 116 rotates synchronously, and the cleaning ring 1217 is used to guide the charging cable 3 by controlling the extension and retraction of the second electric telescopic rod 125 and the third electric telescopic rod 127. The fifth motor 128 is controlled to start according to the direction in which the driver pulls the charging cable 3, thereby driving the second U plate 129 and the cleaning ring 1217 to rotate, so that the side walls of the two cleaning rings 1217 face the direction in which the driver pulls the charging cable 3, so that when the driver pulls the charging cable 3, the pulling force of the charging cable 3 is reduced, which is more labor-saving. At the same time, the sixth motor 1211 is controlled to start, driving the second round rod 1210 to rotate, and the fixing plate 1212 is used to drive the cleaning ring 1217 to rotate, and the inclination angle of the cleaning ring 1217 is adjusted, thereby changing the pulling direction of the charging cable 3. The direction of the pulling is convenient for the driver to better pull the charging gun 4 and the charging cable 3 to the charging place of the new energy vehicle, and the charging cable 3 does not contact the ground when the charging gun 4 is inserted into the new energy vehicle, so as to prevent the charging cable 3 from being constantly rubbed on the ground when the driver takes down the charging cable 3 from the pay-off drum 2, thereby causing a leakage accident. After completing the charging of the new energy vehicle, after the driver pulls out the charging gun 4 from the electric vehicle, the third motor 1110 is controlled to rotate in the reverse direction, so that the traction drum 119 pulls the charging cable 3 into the pay-off drum 2, and at the same time, the first motor 8 and the fourth motor 122 are controlled to rotate in the reverse direction, so that the rotation speed of the fixing ring 116 and the cleaning ring 1217 is the same as the moving speed when the charging cable 3 is pulled.The charging cable 3 is rewound in the cable reel 2. During this process, since the side wall of the cleaning plate 1222 is in contact with the outer wall of the charging cable 3, in the process of retracting the charging cable 3, the two electric slide rails 1218 are controlled to start at the same time to drive the corresponding slide plate 1219 to move, and the moving direction and speed of the two slide plates 1219 are consistent, so that the slide plate 1219 drives the cleaning plate 1222 to move, and the cleaning plate 1222 is used to rub and clean the outer wall of the charging cable 3 to keep the outer wall of the charging cable 3 clean, so as to prevent the outside of the charging cable 3 from being covered with dust and affecting the detection of the charging cable 3 by the ultrasonic detector 1113. In the process of continuously retracting the charging cable 3, multiple ultrasonic detectors 1113 are controlled to start to detect whether the outer wall of the retracted charging cable 3 is damaged, so as to prevent the charging cable 3 from being damaged by foreign objects during the charging process, resulting in damage to the outer wall and affecting the safety of use. After the charging cable 3 is completely retracted, the driver puts the charging gun 4 back to the original position. At this time, the use of the charging pile 1 is completed and it can be used when needed. When charging a new energy vehicle, after the charging gun 4 is inserted into the new energy vehicle, the charging cable 3 is prevented from contacting the ground, so as to prevent the charging cable 3 from being constantly rubbed on the ground when the driver takes down the charging cable 3 from the cable reel 2, which is too long, causing the outer skin of the charging cable 3 to be damaged, exposing the internal conductor to the outside and eventually causing a leakage accident. The traction drum 119 can be used to automatically remove the charging cable 3 from the cable reel 2 and put it into the cable reel 2, reducing the driver's operation steps. At the same time, the cleaning plate 1222 can be used to rub and clean the outer wall of the charging cable 3, so that the outer wall of the charging cable 3 is kept clean, and the outer surface of the charging cable 3 is prevented from being covered with dust and affecting the detection of the charging cable 3 by the ultrasonic detector 1113. The ultrasonic detector 1113 can detect whether the outer wall of the retracted charging cable 3 is damaged, so as to prevent the charging cable 3 from being damaged by foreign objects during the charging process, causing the outer wall to be damaged and affecting the safety of use, which greatly improves the safety and reliability of the device when charging new energy vehicles.
