This may cause damage to the insulation of the charging cable, potentially leading to safety accidents such as short circuits and leakage. Utility Model Content

[0004] The purpose of this invention is to address the problem in the existing technology that the charging cables used in electric vehicle charging stations are usually installed on the outside and are relatively long. This makes the charging cables prone to contact with the ground and friction during use, which may cause damage to the insulation of the charging cables, potentially leading to short circuits and leakage and other safety accidents.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an electric vehicle charging pile with protective function, comprising: a charging pile body, wherein the charging pile body is provided with a charging cable and a charging head, and further comprising:

[0006] A protective housing is fixedly connected to one side of the charging pile body. The outer surface of the charging cable is slidably and sealed to the top and bottom of the protective housing. Two rotating rods are symmetrically and rotatably connected to the inner wall of the protective housing. One end of each rotating rod is fixedly connected to a hollow cylinder. The outer surface of the charging cable is slidably connected to the inside of the two hollow cylinders. A driving mechanism is provided inside the protective housing to drive the rotating rods.

[0007] Preferably, the driving mechanism includes a partition, the second rotating rod is rotatably connected to the partition, the partition is fixedly connected to the protective box, and two first rotating rods are symmetrically rotatably connected to one side of the partition. Gears are fixedly connected to the outer surface of the first rotating rods, and the teeth of the two gears mesh with each other.

[0008] Preferably, pulleys are fixedly connected to the outer surfaces of both rotating rod one and rotating rod two, and belt strips are movably connected to the outer surfaces of the two pulleys. A motor is fixedly connected to one side of the protective box, and the output end of the motor is fixedly connected to one end of one of the rotating rods.

[0009] Preferably, one end of the charging cable is fixedly connected to the side of the charging pile body near the bottom, the other end of the charging cable is fixedly connected to the charging head, and one end of the charging head is movably inserted into the inner wall of the charging pile body near the top.

[0010] Preferably, a fixing rod is fixedly connected to one side of the charging pile body, and an H-shaped plate is rotatably connected to the outer surface of the fixing rod. Guide wheels are rotatably connected to the opposite sides of the two arms of the H-shaped plate.

[0011] Preferably, a U-shaped block is fixedly connected to one side of the protective box near the top, and a second round rod is fixedly connected to one side of the two arms of the U-shaped block. A telescopic rod is rotatably connected to the outer surface of the second round rod, and a first round rod is fixedly connected to one side of the two arms of the H-shaped plate. The first round rod is rotatably connected to the telescopic rod.

[0012] Preferably, the outer surface of the telescopic rod is provided with a spring, and the two ends of the spring are respectively fixedly connected to the two ends of the telescopic rod. The protective box body is movably connected to a box cover on one side by a hinge.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model uses a controller to start a motor, causing its output shaft to drive one of the rotating rods and one of the gears to rotate counterclockwise by an appropriate angle. Then, with the cooperation of two pulleys and belts, the upper rotating rod and the hollow cylinder can be driven to rotate counterclockwise by an appropriate angle. Then, with the meshing of two gears, another gear and another rotating rod can rotate clockwise. At the same time, with the cooperation of the other two pulleys and belts, the lower rotating rod and the hollow cylinder can be rotated by an appropriate angle, so that the two ends of the two hollow cylinders gradually come together, forming a V-shape and maintaining a certain degree of inclination. This makes it convenient for users to pull the charging cable out of the protective box, and the protective box protects the charging cable from friction with the ground, preventing wear and tear on the charging cable, thereby avoiding safety accidents such as short circuits and leakage.

[0015] 2. In this utility model, when the charging head is removed, the outer surface of the charging cable contacts the guide wheel, and the charging cable is pulled, causing it to slide on the guide wheel and rotate. At this time, the guide wheel will be subjected to a force, causing the H-shaped plate to rotate downward around the outer surface of the fixed rod, and simultaneously causing the telescopic rod to retract and the spring to compress. Through the restoring force of the spring, the force on the guide wheel is buffered, which can reduce the friction on the charging cable and thus improve the protection of the charging cable.

The outer surface of the charging cable 101 is slidably connected to the inside of the two hollow cylinders 204. The protective box 2 is provided with a driving mechanism, which is used to drive the rotating rods 209.

[0025] Furthermore, such as Figure 1-4 As shown, the driving mechanism includes a partition 202, a rotating rod 209 rotatably connected to the partition 202, the partition 202 fixedly connected to the protective box 2, and two rotating rods 203 symmetrically rotatably connected to one side of the partition 202. Gears 205 are fixedly connected to the outer surface of the rotating rods 203. The teeth of the two gears 205 mesh with each other. Through the above arrangement, the two rotating rods 203 can rotate in opposite directions.

[0026] Furthermore, such as Figure 1-4 As shown, pulleys 208 are fixedly connected to the outer surfaces of both rotating rod 1 203 and rotating rod 209. Belt strips 207 are movably connected to the outer surfaces of the two pulleys 208. A motor 206 is fixedly connected to one side of the protective housing 2. The output end of the motor 206 is fixedly connected to one end of one of the rotating rods 1 203. Through the interaction of the pulleys 208 and the belt strips 207, the connected rotating rods 1 203 and 209 can rotate synchronously.

[0027] Furthermore, such as Figure 1-4 As shown, one end of the charging cable 101 is fixedly connected to the side of the charging pile body 1 near the bottom, and the other end of the charging cable 101 is fixedly connected to the charging head 102. One end of the charging head 102 is movably inserted into the inner wall of the charging pile body 1 near the top. With the above settings, it is convenient for users to use the charging head 102 to charge electric vehicles.

[0028] Furthermore, such as Figure 1-4 As shown, a fixed rod 3 is fixedly connected to one side of the charging pile body 1. An H-shaped plate 301 is rotatably connected to the outer surface of the fixed rod 3. Guide wheels 302 are rotatably connected to the opposite side of the two arms of the H-shaped plate 301. Through the above arrangement, the H-shaped plate 301 can rotate around the outer surface of the fixed rod 3 at an appropriate angle. The guide wheels 302 guide the charging cable 101.

[0029] Furthermore, such as Figure 1-4As shown, a U-shaped block 304 is fixedly connected to one side of the protective box 2 near the top. A round rod 305 is fixedly connected to the opposite side of the two arms of the U-shaped block 304. A telescopic rod 306 is rotatably connected to the outer surface of the round rod 305. A round rod 303 is fixedly connected to the opposite side of the two arms of the H-shaped plate 301. The round rod 303 is rotatably connected to the telescopic rod 306. Through the above arrangement, the telescopic rod 306 can be retracted or extended, and the two ends of the telescopic rod 306 can be rotated around the round rod 305 and the round rod 303 at appropriate angles.

[0030] Furthermore, such as Figure 1-4 As shown, a spring 307 is provided on the outer surface of the telescopic rod 306. The two ends of the spring 307 are fixedly connected to the two ends of the telescopic rod 306. The cover 201 is movably connected to one side of the protective box 2 through a hinge. Under the restoring force of the spring 307, it plays a certain buffering role.

[0031] Working Principle: When charging an electric vehicle using the charging head 102, the charging head 102 is removed from the charging pile body 1. The controller then starts the motor 206, causing its output shaft to rotate one of the rotating rods 203 and one of the gears 205 counterclockwise by an appropriate angle. Then, with the cooperation of two pulleys 208 and belts 207, the upper rotating rod 209 and the hollow cylinder 204 rotate counterclockwise by an appropriate angle. Next, with the meshing of two gears 205, another gear 205 and another rotating rod 203 rotate clockwise. Simultaneously, with the cooperation of the other two pulleys 208 and belts 207, the lower rotating rod 209 and the hollow cylinder 204 rotate by an appropriate angle, causing the two ends of the two hollow cylinders 204 to gradually approach each other, forming a V-shape and maintaining a certain degree of inclination. This facilitates the user connecting the charging cable 101 from the protective housing 2. The charging cable 101 is pulled out from the inside and protected by the protective housing 2 to prevent it from rubbing against the ground and causing wear, thus avoiding safety accidents such as short circuits and leakage. When the hollow cylinder 204 is kept horizontal, it can also prevent the charging cable 101 from sliding downwards. When the charging head 102 is taken out, the outer surface of the charging cable 101 contacts the guide wheel 302, and the charging cable 101 is pulled, causing it to slide on the guide wheel 302, causing the guide wheel 302 to rotate. At this time, the guide wheel 302 will be subjected to a force, causing the H-shaped plate 301 to rotate downwards around the outer surface of the fixed rod 3. Simultaneously, the telescopic rod 306 retracts, compressing the spring 307. Through the restoring force of the spring 307, the force on the guide wheel 302 is buffered, which can reduce the friction of the charging cable 101 and improve the protection of the charging cable 101.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
