Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle charging, in particular to a hanging type charging device for an electric vehicle. Background Art

[0002] With the strong support of national policies, the number of new energy vehicles (electric vehicles) in China is increasing. In order to adapt to the growth and long-term development of electric vehicles, various regions have increased the construction of charging stations.

[0003] The charging device of existing charging stations is usually a charging pile, on which the charging gun is placed, and the charging cable is hung on the ground. When charging an electric vehicle or putting the charging gun back, the charging cable is heavy and needs to be dragged, which is not only laborious, but also causes friction between the charging cable and the ground, which can easily cause the charging cable to wear and leak electricity, resulting in safety accidents. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a hanging charging device for an electric vehicle.

[0005] The technical solution of this utility model is as follows:

[0006] An electric vehicle suspension charging device comprises a charging pile, a charging gun, a cable and a support frame, wherein a crossbeam is extended forward from the upper end of the support frame, a fixed seat and a sliding seat are arranged on the crossbeam, the sliding seat is located in front of the fixed seat and slides along the crossbeam, the charging pile is arranged near the support frame, the cable is fixed on the fixed seat and the sliding seat, and one end extending out of the sliding seat is connected to the charging gun;

[0007] A vertical cantilever is rotatably connected below the sliding seat, and the rotating shaft is vertically perpendicular to the cross beam. A brake member is rotatably connected on the sliding seat, and the rotating shaft is transversely perpendicular to the cross beam. The rotating shaft of the brake member and the rotating shaft of the cantilever do not intersect. The brake member includes a braking part and a driving part extending in opposite directions from the front and rear directions at the connection point. An inclined groove is provided on the outer side of the cantilever near the upper end. The driving part is slidably connected in the inclined groove and swings with the rotation of the cantilever, driving the braking part to abut or move away from the bottom surface of the cross beam.

[0008] When charging, pull the cantilever to slide on the beam to move the charging gun and stretch the cable, which is convenient and labor-saving. When the cantilever is pulled to the position of the car charging port, the cantilever is rotated, and the driving part of the brake part drives the brake part to rotate upward and press it against the bottom surface of the beam to fix the position of the sliding seat to prevent the heavy cable between the fixed seat and the sliding seat from pulling the sliding seat back. After charging is completed, turn the cantilever back to release the brake part, and then push the cantilever back to the charging pile position. The overall charging process is simple to operate and labor-saving.

[0009] In addition, the cables are hung on the beams through fixed seats and sliding seats, which avoids damage caused by friction with the ground and increases the service life of the cables.

[0010] Preferably, the rotation axis of the brake member is located at the rear side of the cantilever rotation axis, and the brake portion extends rearward and upward.

[0011] When the braking portion contacts the bottom surface of the beam, its backward inclination angle is 20-40 degrees.

[0012] Since the bottom surface of the crossbeam applies a forward friction force to the brake part, the brake part tends to rotate forward, and then the brake part is pressed more tightly against the bottom surface of the crossbeam, thereby improving the braking effect. The 20-40 degree inclination angle enables the crossbeam to apply a forward component force on the brake part that is greater than the downward component force, so that the brake part tends to rotate forward more than the downward component force, and then when the cantilever stops rotating and does not apply force to the brake part, the heavy cable between the fixed seat and the sliding seat can also generate a tensile force, so that the brake part is pressed tightly against the bottom surface of the crossbeam, fix the position of the sliding seat, and then fix the cantilever.

[0013] In order to reduce the amplitude of the cantilever rotation during operation by the user, the cantilever rotation angle is preferably 0-90 degrees.

[0014] In order to make the braking part of the brake member more stably pressed against the bottom surface of the beam, a horizontal groove is extended laterally from the lower end of the inclined groove, and the horizontal groove extends away from the upper end of the inclined groove. When the braking part rotates to press against the bottom surface of the beam, the driving part slides to the lower end of the inclined groove, and the cantilever is further rotated at this time to make the driving part slide into the horizontal groove. Due to the restrictions of the upper and lower sides of the horizontal groove, the driving part cannot rotate, and the braking part is stably pressed against the bottom surface of the beam.

[0015] Preferably, the distance between the upper edge of the horizontal groove and the bottom surface of the beam is greater than the vertical distance between the two ends of the brake member, and the difference is less than 5mm. When the driving part slides into the horizontal groove, it forms an interference fit with the upper edge of the horizontal groove, so that the brake part is pressed more tightly against the bottom surface of the beam, thereby improving the braking effect.

[0016] Preferably, the cantilever is in a circular tube shape, and the sum of the central angles of the inclined groove and the horizontal groove is equal to 90 degrees.

[0017] In order to improve the braking effect of the braking part, an anti-skid pad is provided at the end of the braking part, and the anti-skid pad can also protect the end of the braking part.

[0018] In order to protect the charging gun, a gun seat for placing the charging gun is fixed at the lower part of the cantilever.

[0019] In order to facilitate the movement of the cantilever, a handle is provided at the bottom of the cantilever.

[0020] The utility model provides a suspended charging device for an electric vehicle, which suspends a cable on a crossbeam through a fixed seat and a sliding seat, thereby preventing the cable from rubbing against the ground and increasing its service life.

[0021] In addition, the cable can be stretched in a sliding manner through the cantilever and the sliding seat, which is convenient and labor-saving.

[0022] In addition, a brake is provided on the sliding seat, which can be driven by rotating the cantilever to fix the sliding seat on the crossbeam, thereby preventing the heavy cable between the fixed seat and the sliding seat from pulling the sliding seat, and then pulling the charging gun that is being charged, thereby avoiding damage to the charging gun or the charging port of the car.

[0027] like Figure 1 As shown, the embodiment of the utility model provides an electric vehicle suspension charging device, including an existing charging pile 11, a charging gun 12, a cable 13, and a support frame 21. The charging device also includes the support frame 21, and a crossbeam 22 extends forward from the upper end of the support frame 21. A fixed seat 23 and a sliding seat 24 are provided on the crossbeam 22. The sliding seat 24 is located in front of the fixed seat 23 and slides along the crossbeam 22. The charging pile 1 is arranged close to the support frame 21, and the cable 13 is fixed on the fixed seat 23 and the sliding seat 24, and one end extending out of the sliding seat 24 is connected to the charging gun 12;

[0028] A vertical cantilever 25 is rotatably connected to the bottom of the sliding seat 24, and the rotating shaft is vertically perpendicular to the cross beam 22. A brake member 26 is rotatably connected to the sliding seat 24, and the rotating shaft is transversely perpendicular to the cross beam 22. The rotating shaft of the brake member 26 and the rotating shaft of the cantilever 25 do not intersect. The brake member 26 includes a brake part 261 and a driving part 262 extending in opposite directions from the front and rear directions at the connection point. An inclined groove 251 is provided on the outer side surface of the cantilever 25 near the upper end. The driving part 262 is slidably connected in the inclined groove 251, and swings with the rotation of the cantilever 25, driving the brake part 261 to abut or move away from the bottom surface of the cross beam 22.

[0029] The fixed seat 23 is preferably fixed above the charging pile 11 or near the charging pile 11. The cable 13 extends from the charging pile 11, and after being fixed upward, continues to extend to the sliding seat 24 and is fixedly connected to the sliding seat 24. A preset length of cable 13 is left between the sliding seat 24 and the fixed seat 23, so that the sliding seat 24 can stretch the cable 13 to meet the demand of charging the car. After the cable 13 is connected to the sliding seat 24, it continues to hang down a preset distance, and the end is connected to the charging gun 12. The preset hanging distance can meet the charging gun 12 for plugging into charging ports at different positions, and the cable 13 and the charging gun 12 will not contact the ground.

[0030] The rotation axis of the brake member 26 is preferably located at the rear side of the rotation axis of the cantilever 25, and the brake portion 261 extends rearward and upward. When the brake portion 261 contacts the bottom surface of the crossbeam 22, its backward inclination angle is 20-40 degrees.

[0031] Since the bottom surface of the cross beam 22 applies a forward friction force to the brake part 261, the brake part 261 tends to rotate forward, and the brake part 261 is pressed more tightly against the bottom surface of the cross beam 22, thereby improving the braking effect. The inclination angle of 20-40 degrees enables the cross beam 22 to apply a forward component force on the brake part 261 that is greater than the downward component force, so that the brake part 261 tends to rotate forward more than the downward component force, and when the cantilever 25 stops rotating and does not apply a force to the brake part 26, the heavy cable 13 between the fixed seat 23 and the sliding seat 24 can also generate a tensile force, so that the brake part 261 is pressed tightly against the bottom surface of the cross beam 22, fix the position of the sliding seat 24, and then fix the cantilever 25.

[0032] In order to reduce the amplitude of the rotation of the cantilever 25 during operation by the user, the rotation angle of the cantilever 25 is preferably 0-90 degrees.

[0033] In order to make the braking part 261 of the braking member 26 more stably pressed against the bottom surface of the beam 22, a horizontal groove 252 is extended laterally from the lower end of the inclined groove 251, and the horizontal groove 252 extends in a direction away from the upper end of the inclined groove 251. When the braking part 261 rotates to press against the bottom surface of the beam 22, the driving part 262 slides to the lower end of the inclined groove 251, and the cantilever 25 is further rotated at this time, so that the driving part 262 slides into the horizontal groove 252. Due to the restrictions of the upper and lower sides of the horizontal groove 252, the driving part 262 cannot rotate, and the braking part 261 is stably pressed against the bottom surface of the beam 22.

[0034] Furthermore, the distance between the upper edge of the horizontal groove 252 and the bottom surface of the beam 22 is greater than the vertical distance between the two ends of the brake member 26, and the difference is less than 5mm. When the driving part 262 slides into the horizontal groove 252, it is an interference fit with the upper edge of the horizontal groove 252, so that the brake part 261 is pressed more tightly against the bottom surface of the beam 22, thereby improving the braking effect.

[0035] Preferably, the cantilever 25 is in a circular tube shape, and the sum of the central angles corresponding to the inclined groove 251 and the horizontal groove 252 is equal to 90 degrees.

[0036] In order to improve the braking effect of the braking part 261 , an anti-skid pad 263 is provided at the end of the braking part 261 , and the anti-skid pad 263 can also protect the end of the braking part 261 .

[0037] In this embodiment, the brake member 26 is U-shaped, and the middle position of the two side arms of the U-shape is rotatably connected to the sliding seat 24. The side arm parts close to the two ends of the U-shape are the driving part 262, and the bent part is the brake part 261. The ends of the driving part 262 are bent toward each other and slide in the inclined groove 251 and the horizontal groove 252.

[0038] In this embodiment, the brake member 26 is formed by bending a metal rod and is located outside the sliding seat 24 .

[0039] In this embodiment, the cantilever 25 is a hollow tube, and the cable 13 preferably passes through the cantilever 25 from top to bottom, so that the cantilever 25 can provide a certain degree of protection for the cable 13 and limit the shaking of the cable 13 to avoid accidental injury to people by the cable 13 during the movement of the cantilever 25.

[0040] Furthermore, a gun seat 3 for placing the charging gun 12 may be fixed at the lower part of the cantilever 25 to protect the charging gun 12 .

[0041] In order to facilitate the movement of the cantilever 25 , a handle 4 may be further provided at the lower portion of the cantilever 25 .

[0042] When the charging device of the present application is used to charge a car, the cantilever 25 is pulled to slide on the crossbeam 22 to move the charging gun 12 and stretch the cable 13. When the cantilever 25 is pulled to the position of the car charging port, the cantilever 25 is rotated, and the driving part 262 of the brake member 26 drives the brake part 261 to rotate upward and press against the bottom surface of the crossbeam 22, so as to fix the position of the sliding seat 24, and then the charging gun 12 is removed and connected to the car.

[0043] After charging is completed, the charging gun 12 is hung back in the gun seat 3, the cantilever 25 is rotated back to release the brake member 26, and then the cantilever 25 is pushed back to the position of the charging pile 11.

[0044] The utility model provides a suspension type charging device for electric vehicles, which suspends the cable 13 on the crossbeam 22 through the fixing seat 23 and the sliding seat 24, so as to avoid friction with the ground and increase the service life of the cable 13.

[0045] In addition, the cable 13 can be stretched in a sliding manner through the cantilever 25 and the sliding seat 24, which is convenient and labor-saving.

[0046] In addition, a brake member 26 is provided on the sliding seat 24. The brake member 26 can be driven by rotating the cantilever 25 to fix the sliding seat 24 on the beam 22, thereby preventing the heavy cable 13 between the fixed seat 23 and the sliding seat 24 from pulling the sliding seat 24, and then pulling the charging gun 12 being charged, thereby avoiding damage to the charging gun 12 or the charging port of the car.
