[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 7 A new energy energy-saving charging pile for electric vehicles comprises a shell 1, a turntable bracket 2 is connected to the inner bottom surface of the shell 1 by bolts, a reel 3 is rotatably connected to the inner side of the turntable bracket 2, a wire 4 is wound around the outer surface of the reel 3, one end of the wire 4 is connected to a charging gun 5, the outer surface of the reel 3 is connected to a first pulley 6 by an axis, the outer surface of the first pulley 6 is transmission-connected to a synchronous belt 7, one end of the synchronous belt 7 is transmission-connected to a second pulley 8, the end center of the second pulley 8 is fixedly connected to a transmission gear 9 by an axis, the transmission gear 9 is meshedly connected to a double-layer gear 10, the double-layer gear 10 is meshedly connected to a rack 11, and a counterweight ball 12 is threadedly connected to the bottom end of the rack 11, a connecting plate 13 is connected to the inner wall of the shell 1 by bolts, a box body 14 is fixed to one end of the connecting plate 13, a pulley bracket 15 is installed on one side of the inner side of the shell 1, the inner side of the pulley bracket 15 is rotationally connected to two pulleys 16, and a sleeve 17 is fixedly connected to one side of the shell 1.

[0031] Specifically, a through hole is formed on one side of the housing 1, and the wire 4 is inserted into the through hole. The housing 1 is fixedly connected to the side of the through hole with a No. 1 protective cover 18. The advantage is that before charging the electric vehicle, the charging gun 5 is removed, and the end of the wire 4 close to the charging gun 5 is pulled, so that the reel 3 can rotate, so that the reel 3 can release the wire 4, and charging can be carried out after the charging gun 5 is connected to the charging port of the electric vehicle. By opening a through hole on one side of the housing 1 for the wire 4 to pass through, the No. 1 protective cover 18 can play a certain protective role on the through hole to prevent rainwater from entering on rainy days.

[0032] Specifically, a connecting plate 13 is welded on each side of the box body 14, and rectangular holes are formed through the top and bottom surfaces of the box body 14, and the rack 11 is slidably connected in the rectangular holes. A partition 19 is fixedly connected to the inner wall of the shell 1, and the shaft end of the second pulley 8 is rotatably connected to the partition 19. The advantage is that the box body 14 can be fixed by setting two connecting plates 13. When charging is completed, the charging gun 5 is removed from the charging port of the electric vehicle, and then the charging gun 5 is inserted into the sleeve 17. At this time, the rack 11 will automatically move downward under the gravity of the counterweight ball 12. In this process, there is no need to use additional power equipment to drive the rack 11 to move, and the downward movement is achieved only by the deadweight of the counterweight ball 12 and the rack 11.

[0033] Specifically, a limit plate is integrally connected to the bottom end of the rack 11, and the weight ball 12 includes a screw rod disposed on the outer surface, and the screw rod is threadedly connected to the rack 11. The advantage is that by arranging a limit plate at the bottom end of the rack 11, the maximum stroke of the rack 11 can be limited during the rising process, thereby preventing the rack 11 from slipping out of the box body 14 and losing the meshing connection with the double-layer gear 10, and the screw rod is provided to facilitate the connection between the weight ball 12 and the rack 11.

[0034] Specifically, a U-shaped plate is fixedly connected to the outer surface of the pulley bracket 15, and the outer surface of the pulley 16 slides in contact with the wire 4. Figure 2 It can be seen that when the wire 4 is pulled, the reel 3 can be easily rotated with the assistance of the two pulleys 16, so that the wire 4 wrapped around its outer surface can be released. In this process, the reel 3 will rotate clockwise, so that the reel 3 drives the No. 1 pulley 6 to rotate, and the No. 1 pulley 6 cooperates with the synchronous belt 7 to drive the No. 2 pulley 8 to rotate, and the No. 2 pulley 8 drives the transmission gear 9, and the transmission gear 9 drives the double-layer gear 10, and the double-layer gear 10 drives the rack 11 to rise. The length of the wire 4 pulled out determines the height of the rack 11 rising. Conversely, the height of the rack 11 rising provides a prerequisite for winding up the wire 4 later.

[0035] Specifically, the box body 14 is internally provided with a transmission gear 9 and a double-layer gear 10, the diameters of the first pulley 6 and the second pulley 8 are the same, and the transmission ratio between the double-layer gear 10 and the transmission gear 9 is 1:2. The advantage is that the charging gun 5 is immediately returned to its position after charging is completed, the rack 11 descends and drives the double-layer gear 10 to rotate clockwise, the double-layer gear 10 drives the transmission gear 9 to rotate counterclockwise, and the transmission gear 9 drives the second pulley 8 to rotate counterclockwise. The reel 3 can rotate counterclockwise through the cooperation of the synchronous belt 7 and the first pulley 6, so that the reel 3 can automatically reel the wire 4. Since the large gear of the double-layer gear 10 is meshed with the transmission gear 9, and its small gear is meshed with the rack 11, the rotation speed of the transmission gear 9 can be increased, thereby accelerating the reel 3 reeling speed, so that the rack 11 can complete the reeling of the wire 4 in a limited length, and no power equipment is needed in the whole process, which is conducive to reducing cost investment and also helps to save energy.

[0036] Specifically, a soft pad 20 is fixedly connected to the inner bottom surface of the housing 1, and a spherical groove is provided on the upper surface of the soft pad 20, and the spherical groove fits the counterweight ball 12. The advantage is that the soft pad 20 can support the counterweight ball 12, so that the counterweight ball 12 is prevented from directly contacting the bottom of the housing 1 after falling, which can reduce noise on the one hand and prevent the bottom of the housing 1 from being damaged by impact on the other hand.

[0037] Specifically, a No. 2 protective cover 21 is fixedly connected to the outer surface of the shell 1, the sleeve 17 is arranged inside the No. 2 protective cover 21, and the charging gun 5 is plugged into the sleeve 17. The advantage is that inside the shell 1, the internal space of the shell 1 is divided by the partition 19, and the components such as the turntable bracket 2 are installed in one space, and the electrical components required for various charging piles are installed in another space. The end of the wire 4 away from the charging gun 5 is connected to the power transmission port. A control panel for user operation is also provided on the front of the shell 1. Recharge and payment can be made using the control panel. By providing the No. 2 protective cover 21, the sleeve 17 and the charging gun 5 inserted into the sleeve 17 can be protected.

[0038] Specifically, a cover 22 is fixedly connected to the top surface of the sleeve 17, and a micro motor 23 is installed in the cover 22. The output end of the micro motor 23 is connected to the worm 24, and the worm 24 is connected to the worm wheel 25 through transmission. The internal thread of the worm wheel 25 is connected to the locking rod 26. The advantage is that the micro motor 23 is connected to the control system of the charging pile. When the user pays the fee, the micro motor 23 starts immediately and drives the worm 24 to rotate. The worm 24 drives the worm wheel 25, and the worm wheel 25 forces the locking rod 26 to move upward. At this time, the locking rod 26 is disengaged from the socket opened on the front outer surface of the charging gun 5, so that the locking rod 26 no longer locks the charging gun 5, so that the charging gun 5 can be pulled out of the sleeve 17 to start charging.

[0039] Specifically, a socket is provided on the outer surface of the front end of the charging gun 5, and the socket is adapted to the locking rod 26, and the top of the locking rod 26 is fixedly connected to the limiting rod 27. The advantage is that when charging is completed, the user reinserts the charging gun 5 into the sleeve 17, and the micro motor 23 drives the worm 24 to rotate in the reverse direction, so that the locking rod 26 is finally reinsert into the socket of the charging gun 5, so that the charging gun 5 can be locked, so that the charging gun 5 cannot be pulled out without paying for charging, and people are prevented from pulling out the charging gun 5 at will, thereby enhancing safety. The limiting rod 27 is inserted into the upper surface of the cover 22, which can limit the locking rod 26, and prevent the locking rod 26 from rotating with the worm gear 25, but instead move up and down.

[0040] When in use, first pay the fee through the control panel installed on the front side of the shell 1, the control system starts the micro motor 23 to drive the worm 24 to rotate, the worm 24 drives the worm wheel 25, and the worm wheel 25 forces the locking rod 26 to move upward, at this time the locking rod 26 is disengaged from the socket provided on the front end outer surface of the charging gun 5, so that the locking rod 26 no longer locks the charging gun 5, so that the charging gun 5 can be pulled out of the sleeve 17, and the wire 4 is pulled so that the reel 3 is driven to rotate clockwise with the cooperation of the two pulleys 16, so that the reel 3 releases the wire 4 so that it has enough length so that the charging gun 5 can be connected to the charging port of the electric vehicle, thus completing the charging; after the charging is completed, the user unplugs the charging cable from the charging port of the electric vehicle. Gun 5, then insert the charging gun 5 into the sleeve 17, and the micromotor 23 drives the worm 24 to rotate in the reverse direction, so that the locking rod 26 is finally reinserted into the socket of the charging gun 5, so that the charging gun 5 can be locked. In this process, since the counterweight ball 12 has a certain deadweight, it can drive the rack 11 to move downward, and the rack 11 descends to drive the double-layer gear 10 to rotate clockwise, and the double-layer gear 10 drives the transmission gear 9 to rotate counterclockwise, and the transmission gear 9 drives the second pulley 8 to rotate counterclockwise. Through the cooperation of the synchronous belt 7 and the first pulley 6, the reel 3 can rotate counterclockwise, so that the reel 3 can automatically reel the wire 4, avoiding the wire 4 from being scattered outside and not neat, and it is also easy to cause safety hazards.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
