DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 7In an embodiment of the present invention, a movable charging pile for a new energy electric vehicle includes a hanging rail 100, a control component 300, and a charging gun 500. The hanging rail 100 is used to be fixed on the ceiling of an underground parking lot. An electric drive mobile platform 110 is installed on the hanging rail 100. The electric drive mobile platform 110 can be electrically driven and moved on the hanging rail 100. The control component 300 is installed at the bottom end of the electric drive mobile platform 110. A cable 510 is connected between one end of the charging gun 500 and the control component 300. The charging pile also includes a storage shell 400, a guide mechanism 700, and a drive mechanism 600. The storage shell 400 is fixedly installed at the bottom end of the control component 300. Multiple C-shaped grooves 410 are provided at both ends of the interior of the shell 400. The storage shell 400 is used to store the cable 510 through the C-shaped grooves 410. The bottom end of the storage shell 400 is fixedly connected to the outer chassis 420. Inner chassis 430 are provided on the inner sides of both ends of the outer chassis 420. An S-shaped groove 440 is provided between the outer chassis 420 and the two inner chassis 430. The guide mechanism 700 moves in a circle along the S-shaped groove 440. The guide mechanism 700 is used to guide the cable 510. The driving mechanism 600 is installed below the storage shell 400. The driving mechanism 600 is used to drive the guide mechanism 700 to move along the S-shaped groove 440 in an 8-shaped pattern.

[0034] Specifically, the C-shaped groove 410 is spiral, and the multiple C-shaped grooves 410 at both ends of the storage shell 400 are staggered up and down, so that the cable 510 can be gradually wound downward in an 8-shaped shape along the multiple C-shaped grooves 410 in the storage shell 400. When in use, the electric drive moving platform 110 drives the charging gun 500 to move to the corresponding position along the hanging rail 100, and the driving mechanism 600 drives the guide mechanism 700 to move forward along the 8-shaped groove 440 in an 8-shaped trajectory. The guide mechanism 700 moves to release the cable 510, thereby releasing the cable 510. When reeling, the driving mechanism 600 drives the guide mechanism 700 to move in the opposite direction along the 8-shaped trajectory, so that the cable 510 is laid in the multiple C-shaped grooves 410 from top to bottom in an 8-shaped shape, thereby avoiding the cable 510 from twisting in a single direction when releasing and storing, and facilitating the access of the charging gun 500 and the storage of the cable 510.

[0035] Example 1

[0036] like Figures 8-9The cam 730 of the embodiment of the present invention is a kind of cam 730 that is used for the purpose of adjusting the position of the support frame 710, and the cam 730 of the embodiment of the present invention is a kind of cam 730 that is used for the purpose of adjusting the position of the support frame 710, and the cam 730 of the embodiment of the present invention is a kind of cam 730 that is used for the purpose of adjusting the position of the support frame 710. The wall is fixedly connected with a gear ring 460, which is used for transmission connection with the sliding sleeve 750. The bottom end of the guide block 730 is fixedly connected with a connecting sleeve 732. The outer wall of the connecting sleeve 732 is rotatably connected with a sleeve 740. The top end of the outer wall of the sleeve 740 is fixedly connected with a transmission gear 1 741. The outer wall of the bottom end of the sleeve 740 is fixedly connected with a bevel gear 2 742. The top end of the outer wall of the sliding sleeve 750 is fixedly connected with a bevel gear 3 752. The bottom end of the sliding sleeve 750 is fixedly sleeved with the transmission gear 2 751. The top end of the sliding sleeve 750 is rotatably sleeved with the bottom end of the connecting sleeve 732. A rotatable bevel gear 1 733 is installed in the middle position of the outer wall of the connecting sleeve 732. The bevel gear 1 733 meshes with the bevel gear 2 742 and the bevel gear 3 752. The height of one of the two gear rings 460 is the same as that of the transmission gear 1 741, and the height of the other gear ring 460 is the same as that of the transmission gear 2 751.

[0037] In this embodiment, the guide block 730 moves in an 8-shaped manner along the 8-shaped groove 440. When the guide block 730 is located at one end of the 8-shaped groove 440, the transmission gear 1 741 is engaged with a gear ring 460. When the guide block 730 moves forward, the transmission gear 1 741 is driven to rotate through the gear ring 460. The transmission gear 1 741 drives the sliding sleeve 750 to rotate in the opposite direction through the bevel gear 2 742, the bevel gear 1 733 and the bevel gear 3 752, thereby driving the threaded rod 710 to rotate in the opposite direction. The threaded rod 710 is screwed together with the internal threaded sleeve 731. When the threaded rod 710 rotates in the opposite direction, the threaded rod 710 moves upward relative to the guide block 730. When the guide mechanism 700 is located at the other end of the figure-eight groove 440, the other gear ring 460 engages with the transmission gear 2 751, so that when the guide mechanism 700 rotates in the forward direction of the figure-eight, the threaded rod 710 continues to move upward, so that when the cable 510 is released, the fixed plate 760 gradually moves upward while orbiting. When the guide mechanism 700 orbits in the reverse direction of the figure-eight, the fixed plate 760 gradually moves downward while orbiting, thereby storing the cable 510.

[0038] like Figures 9-10 As shown, in this embodiment, a transmission gear set 770 is connected between the threaded rod 710 and the two clamping wheels 761, and the two clamping wheels 761 transmit reverse transmission. The transmission gear set 770 includes an intermediate gear 773 and two speed gears 772. The top of the threaded rod 710 is fixedly sleeved with a flat gear 1 771. The flat gear 1 771 is engaged with one speed gear 772 and the intermediate gear 773. The intermediate gear 773 is engaged with the other speed gear 772. The bottom end of the clamping wheel 761 is fixedly connected with a flat gear 2 774. The flat gear 2 774 is engaged with the adjacent speed gear 772. The other two ends of the top surface of the fixed plate 760 are rotatably connected to the contact wheels 762.

[0039] During specific implementation, when the threaded rod 710 rotates forward, it drives a clamping wheel 761 to rotate forward through a speed gear 772 and a flat gear 2 774. At the same time, the threaded rod 710 drives another clamping wheel 761 to rotate in the opposite direction through the intermediate gear 773 and another speed gear 772. The cable 510 is clamped by the two clamping wheels 761. At the same time, the rotation of the clamping wheels 761 realizes the active transportation of the cable 510. When the cable 510 is stored, the cable 510 is transported backward relative to the forward direction of the fixed plate 760, so that the cable 510 is squeezed into the C-shaped groove 410, thereby realizing the storage of the cable 510.

[0040] Example 2

[0041] like Figures 6-7 As shown, in this embodiment, the driving mechanism 600 includes a driving motor 630, the bottom end of the storage shell 400 is fixedly connected to the fixing frame 470, the bottom end of the support platform 450 is fixedly connected to the fixing frame 470, the outer wall of the support platform 450 is rotatably sleeved with a rotating ring 610, both ends of the rotating ring 610 are provided with a protrusion 611, and a driving gear 1 620 is provided below the rotating ring 610, the driving gear 1 620 is rotatably sleeved with the bottom end of the adjacent support platform 450, and the gear ring 460 is connected to the driving gear 1 620 just below. 20, the drive motor 630 is fixedly connected to the fixed frame 470, the bottom surface of the fixed frame 470 is located between the two drive gears 1 620 and is transmission-connected to two mutually meshing drive gears 2 631, and the drive gear 2 631 is meshed with the adjacent drive gear 1 620, the output end of the drive motor 630 is transmission-connected to a drive gear 2 631, and the bottom end of the electric drive mobile platform 110 is fixedly connected to the shell 200, which is used to surround the control component 300 and the storage shell 400.

[0042] During specific implementation, the driving motor 630 drives the two driving gears 1 620 to rotate through the two driving gears 2 631, and the driving gear 1 620 drives the rotating ring 610 to rotate, so that the two rotating rings 610 rotate towards each other. When the rotating ring 610 rotates, the sliding seat 720 is pushed through the protrusion 611, thereby pushing the guide block 730 to move along the eight-shaped groove 440. The two rotating rings 610 are misaligned between the upper and lower parts, thereby avoiding interference between the protrusions 611 on the two rotating rings 610, and realizing the forward or reverse cyclic movement of the guide block 730 along the eight-shaped groove 440 through the driving mechanism 600.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
