Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle charging, in particular to an electric vehicle charging pile with an automatic gun collection mechanism. Background Art

[0002] As the energy crisis continues to intensify and environmental awareness continues to increase, new energy vehicles (electric vehicles) that are green and environmentally friendly have come into being, and with them comes the problem of charging.

[0003] At present, many regions have invested in building charging stations to meet social needs. Most of the existing charging stations are separate charging piles, with charging guns plugged into the charging piles and charging cables hanging randomly. Since the charging cables are very thick and heavy, when charging electric vehicles or putting the charging guns back, the charging cables are dragged on the ground, which is not only very laborious, but also causes friction between the charging cables and the ground, which can easily cause the charging cables to wear and leak electricity, resulting in safety accidents.

[0004] In addition, since the charging cable is heavy, it is very difficult to take and put the charging gun, which may lead some lazy people to place the charging gun directly on the ground after charging. This not only easily dirtys the charging gun, but also easily runs over the charging gun or charging cable when the following vehicle drives into the charging position, shortening the service life of the charging gun and charging cable. Utility Model Content

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an electric vehicle charging pile with an automatic gun collection mechanism.

[0006] The technical solution of this utility model is as follows:

[0007] An electric vehicle charging pile with an automatic gun collection mechanism comprises a charging host, a charging cable and a charging gun. A vertical column is fixed on the charging host, and a sliding beam extends forward from the upper end of the vertical column.

[0008] A fixed wire seat is fixed on the sliding beam corresponding to the upper position of the charging host, and a wire moving seat is also provided on the sliding beam. The wire moving seat is located in front of the fixed wire seat and slides along the sliding beam. Two folding arms are provided between the fixed wire seat and the wire moving seat. The lower ends of the two folding arms are hingedly connected, and the upper ends are respectively hinged on the fixed wire seat and the wire moving seat. An elastic telescopic member is connected between the two folding arms near the lower end.

[0009] The charging cable is fixedly connected to the cable fixing seat, two folding arms and the cable moving seat, and the charging gun is located below the cable moving seat.

[0010] In the above scheme, the two folding arms have the same length, so that the two folding arms are always symmetrically arranged relative to the vertical plane during the movement of the wire moving seat, so that the wire moving seat can slide to a position extremely close to the charging host, and then retract the charging gun to the side of the charging host.

[0011] Furthermore, a hinge is provided at the lower end of the two folding arms, and the lower ends of the two folding arms are hinged at both ends of the hinge respectively, and the two folding arms are arranged front and back, which not only facilitates the setting of the elastic telescopic part, but also can adapt to the harder and thicker characteristics of the charging cable, so that the charging cable has a larger distance to be bent.

[0012] In order to prevent the elastic telescopic part from pulling the two folding arms together too quickly, causing the two folding arms to collide, or causing the charging gun or charging cable to shake too violently and be damaged, a sealing rubber sleeve is fixed on the outside of the elastic telescopic part. The sealing rubber sleeve is provided with an air inlet and an air outlet. A baffle is hinged on the inside of the air inlet. The air inlet is larger than the air outlet, and the diameter of the air outlet is 3-6mm.

[0013] When the elastic telescopic part is compressed, the gas in the sealing rubber sleeve presses the baffle against the air inlet, and the gas can only be discharged from the smaller air outlet. Due to the slow exhaust speed, the air pressure in the sealing rubber sleeve increases, thereby slowing down the retraction speed of the elastic telescopic part, so that the two folding arms, the cable moving seat, the charging cable and the charging gun move slowly toward the charging host.

[0014] In order not to affect the stretching of the charging cable during charging, the diameter of the air inlet is 4-6 times the diameter of the air outlet. When the elastic telescopic member is stretched, air can quickly enter the sealing rubber sleeve from the air inlet without exerting additional resistance to the rotation of the two folding arms.

[0015] In order to facilitate the stretching of the charging cable, a vertical push arm is connected under the cable mover.

[0016] Furthermore, a lock is slidably connected to the wire moving seat, and the push arm is horizontally rotatably connected to the wire moving seat. A slide groove is provided on the outer side near the upper end. The lower end of the lock cooperates with the slide groove and rises or falls with the rotation of the push arm to drive the upper end of the lock to contact or move away from the bottom surface of the sliding beam.

[0017] The lock can fix the position of the cable holder so that the charging gun will not be pulled backward by the charging cable when charging, thereby preventing the charging gun from being damaged or pulled out of the charging socket.

[0018] In order to achieve the lifting and lowering of the lock piece and a stable locking effect, the slide groove includes an upwardly inclined arc groove and a horizontal groove connecting the upper end of the arc groove, and the horizontal groove extends away from the lower end of the arc groove.

[0019] In order to improve the locking effect of the lock, an anti-skid pad is provided on the upper end of the lock, and the anti-skid pad can also protect the upper end of the lock.

[0020] In order to protect the charging gun, a gun seat for placing the charging gun is fixed to the lower part of the push arm.

[0021] The utility model provides an electric vehicle charging pile with an automatic gun collection mechanism, which suspends a charging line on a sliding beam through a line fixing seat and a line moving seat, thereby preventing the charging line from rubbing against the ground and increasing its service life.

[0022] In addition, through the two folding arms and the elastic telescopic parts connected between the two folding arms, the wire moving seat can be moved backward to the position of the charging host without human push, and then the charging gun can be retracted to the side of the charging host.

[0023] In addition, the setting of the push arm and the lock not only facilitates the stretching of the charging cable, but also can lock the position of the cable shifter to protect the charging gun from being pulled by the elastic telescopic part and the charging cable during charging, thereby preventing the charging gun from being damaged or pulled out of the charging port.

[0029] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides an electric vehicle charging pile with an automatic gun collection mechanism, including a charging host 11, a charging line 12 and a charging gun 13. A vertical column 21 is fixed on the charging host 11, and a sliding beam 22 extends forward from the upper end of the vertical column 21;

[0030] A fixed wire seat 23 is fixed on the sliding beam 22 corresponding to the upper position of the charging host 11, and a wire moving seat 24 is also provided on the sliding beam 22. The wire moving seat 24 is located in front of the fixed wire seat 23 and slides along the sliding beam 22. Two folding arms 25 are provided between the fixed wire seat 23 and the wire moving seat 24. The lower ends of the two folding arms 25 are hingedly connected, and the upper ends are respectively hinged on the fixed wire seat 23 and the wire moving seat 24. An elastic telescopic member 26 is connected between the two folding arms 25 near the lower end.

[0031] The charging cable 12 is fixedly connected to the cable fixing seat 23, two folding arms 25 and the cable moving seat 24. The charging gun 13 is located below the cable moving seat 24 and does not touch the ground.

[0032] The charging cable 12 is suspended on the sliding beam 22 through the cable fixing seat 23 and the cable moving seat 24 to prevent it from rubbing on the ground and to increase its service life.

[0033] By hingedly connecting two folding arms 25 between the line fixing seat 23 and the line moving seat 24, and connecting the elastic telescopic parts 26 between the folding arms 25, after charging is completed, the charging gun 13 is released, and the two folding arms 25 are pulled closer by the elastic telescopic parts 26, driving the line moving seat 24 to move toward the line fixing seat 23, and then retracting the charging gun 13 to the side of the charging host 11, so as to prevent the charging gun 13 from being damaged by being randomly discarded.

[0034] Preferably, the two folding arms 25 have the same length, so that the two folding arms 25 are always symmetrically arranged relative to the vertical plane during the movement of the wire moving seat 24, so that the wire moving seat 24 can slide to a position extremely close to the charging host 11, and then retract the charging gun 13 to the side of the charging host 11.

[0035] Furthermore, hinges are provided at the lower ends of the two folding arms 25, the lower ends of the two folding arms 25 are respectively hinged at both ends of the hinges, and the two folding arms 25 are arranged front and back, and the elastic telescopic member 26 is located on one side of the two folding arms 25. Not only is it convenient to arrange the elastic telescopic member 26, but it can also adapt to the harder and thicker characteristics of the charging cable 12, so that the charging cable 12 has a larger distance to bend.

[0036] like Figure 2 As shown, in this embodiment, the elastic telescopic member 26 is a telescopic spring.

[0037] In order to prevent the elastic telescopic member 26 from pulling the two folding arms 25 together too fast, causing the two folding arms 25 to collide, or causing the charging gun 13 or the charging cable 12 to shake too violently and be damaged, a sealing rubber sleeve 27 is fixedly sleeved on the outside of the elastic telescopic member 26, and an air inlet 271 and an air outlet 272 are provided on the sealing rubber sleeve 27. A baffle 273 is hinged on the inside of the air inlet 271. The air inlet 271 is larger than the air outlet 272, and the air outlet 272 is smaller in size to slow down the outflow speed of the air in the sealing rubber sleeve 27. In this embodiment, the diameter of the air outlet 272 is 3-6 mm. The air inlet 271 and the air outlet 272 can be set in one or more groups according to actual conditions.

[0038] When the elastic telescopic part 26 is compressed, the air in the sealing rubber sleeve 27 presses the blocking piece 273 against the air inlet 271, and the air can only be discharged from the smaller air outlet 272. Due to the slow exhaust speed, the air pressure in the sealing rubber sleeve 27 increases, thereby slowing down the retraction speed of the elastic telescopic part 26, so that the two folding arms 25, the cable moving seat 24, the charging cable 12 and the charging gun 13 move slowly toward the charging host 11.

[0039] In order not to affect the pulling apart of the two folding arms 25 during charging, i.e. stretching the charging cable 12, the diameter of the air inlet 271 is 4-6 times the diameter of the air outlet 272. When the elastic telescopic member 26 is stretched, air can quickly enter the sealing rubber sleeve 27 from the air inlet 271, and no negative pressure will be generated in the sealing rubber sleeve 27, which will apply additional resistance to the rotation of the two folding arms 25, thereby ensuring the smooth sliding of the cable shifting seat 24.

[0040] For example Figure 1 As shown, in order to facilitate the stretching of the charging cable 12, a vertical push arm 28 is connected below the cable shifting seat 24. The push arm 28 is horizontally rotatably connected to the cable shifting seat 24, and a slide groove 281 is provided on its outer side near the upper end. A lock 29 is slidably connected to the cable shifting seat 24, and the lock 29 can slide vertically, and the lower end of the lock 29 cooperates with the slide groove 281.

[0041] When the push arm 28 is rotated, the slide groove 281 thereon drives the lower end of the lock member 29 to rise or fall, thereby driving the upper end of the lock member 29 to contact or move away from the bottom surface of the sliding beam 22, thereby completing the locking and unlocking of the position of the wire shifting seat 24.

[0042] The lock 29 can fix the position of the wire moving seat 24 so that the charging gun 13 will not be pulled backward by the charging wire 12 when charging, thereby preventing the charging gun 13 from being damaged or pulled out of the charging socket.

[0043] In order to achieve the lifting and lowering of the lock 29 and the stable locking effect, the slide groove 281 includes an upwardly inclined arc groove and a horizontal groove connecting the upper end of the arc groove, and the horizontal groove extends away from the lower end of the arc groove. The lower end of the lock 29 and the lower edge of the horizontal groove are interference fit, and then when the lower end of the lock 29 slides into the horizontal groove, the top end of the lock 29 can be pressed more tightly against the bottom surface of the sliding beam 22, thereby improving the locking effect.

[0044] In order to improve the locking effect of the lock member 29 , an anti-skid pad 291 is provided at the upper end of the lock member 29 , and the anti-skid pad 291 can also protect the upper end of the lock member 29 .

[0045] In order to prevent the user from rotating the push arm 28 too much to lock the position of the wire shifting seat 24, in the present embodiment, the rotation angle of the push arm 28 is 0-90 degrees, that is, when the lower end of the locking member 29 moves from one end of the slide groove 281 to the other end, the rotation angle of the push arm 28 is less than or equal to 90 degrees, preferably equal to 90 degrees.

[0046] In this embodiment, the two folding arms 25 are preferably square tubes, and the push arm 28 is preferably a round tube. The charging cable 12 passes through the two folding arms 25 and the push arm 28 to protect the charging cable 12. At the same time, it can also limit the shaking of the charging cable 12 during the sliding process of the cable moving seat 24, thereby reducing the service life of the cable moving seat 24 or accidentally injuring people.

[0047] Furthermore, in order to protect the charging gun 13 , a gun seat 3 for placing the charging gun 13 may be fixed to the lower part of the push arm 28 .

[0048] In order to facilitate the movement of the push arm 28, a handle 4 may be further provided at the lower portion of the push arm 28.

[0049] When the charging pile of the present application is charging a car, the push arm 28 is pulled to slide forward on the sliding beam 22 to move the charging gun 13. During the movement, the two folding arms 25 are pulled apart, the angle between the two gradually increases, and the elastic telescopic member 26 connecting the two is gradually stretched. When the push arm 28 is pulled to the position of the car charging port, the push arm 28 is rotated and pressed against the bottom surface of the sliding beam 22 by the lock 29, the position of the wire moving seat 24 is fixed, and the charging gun 13 is removed to charge the car.

[0050] After charging is completed, the charging gun 13 is hung back in the gun seat 3, the push arm 28 is rotated back to unlock the lock 29, and then the push arm 28 is released. The push arm 28 will drive the charging gun 13 to move toward the charging host 11 under the action of the elastic telescopic member 26 until it returns to the side of the charging host 11 without manual operation.

[0051] The utility model provides an electric vehicle charging pile with an automatic gun collection mechanism, which suspends a charging line 12 on a sliding beam 22 through a line fixing seat 23 and a line moving seat 24, thereby preventing the charging line 12 from rubbing against the ground and increasing its service life.

[0052] In addition, through the two folding arms 25 and the elastic telescopic parts 26 connected between the two folding arms 25, the wire moving seat 24 can be moved backward to the position of the charging host 11 without human push, and then the charging gun 13 can be retracted to the side of the charging host 11 to prevent the charging gun 13 from being damaged by being randomly discarded.

[0053] In addition, the setting of the push arm 28 and the lock 29 not only facilitates the stretching of the charging cable 12, but also can lock the position of the cable shifting seat 24 to protect the charging gun 13 from being pulled by the elastic telescopic member 26 and the charging cable 12 during charging, thereby avoiding damage to the charging gun 13 or being pulled out of the charging port.
