When the lifting platform 16 needs to be controlled to move, the PLC controls the second motor 26 to be started, the rotating shaft 27 is made to rotate, the wire coil 29 is driven to rotate, and therefore the connecting wire 30 is tightened or loosened, when the connecting wire 30 is tightened, the connecting wire 30 drives the lifting platform 16 to ascend and store the cable 8, when the connecting wire 30 is loosened, the lifting platform 16 descends, and therefore a user can conveniently take out the cable 8 to charge the electric automobile.

Preferably, the connection line 30 is a carbon line in order to secure the strength of the connection line 30 by utilizing the characteristics of high strength and tensile strength of the carbon line.

Preferably, in order to ensure the moving stability of the lifting platform 16, both sides of the lifting platform 16 are provided with a sliding ring 31 and a sliding rail 32, the sliding ring 31 is fixed on the lifting platform 16, the sliding rail 32 is U-shaped, both ends of the sliding rail 32 are fixed on the inner wall of the storage box 7, and the sliding ring 31 is sleeved on the sliding rail 32. The slide rail 32 fixed in position fixes the moving direction of the slide ring 31, and the elevating platform 16 is raised and lowered smoothly.

Preferably, in order to prevent the cable 8 from being detached from the roller 19, the roller 19 is provided with a limiting plate 33 at both sides thereof, and the limiting plate 33 is fixed on the cross bar 18. The range of the cable 8 sliding left and right on the roller 19 is restricted by the two restricting plates 33, and the cable 8 is prevented from falling off the roller 19.

Preferably, in order to prevent the roller 19 from sliding on the cross bar 18, a clamping block 34 is arranged on one side of the vertical rod 20 close to the limiting plate 33, one end of the clamping block 34 is fixed on the vertical rod 20, and the other end of the clamping block 34 abuts against the limiting plate 33. The sliding range of the limiting plate 33 is limited by the clamp block 34, thereby preventing the roller 19 from sliding on the cross bar 18.

Preferably, in order to facilitate the rotation of the roller 19, a recess is formed on one side of the clamping block 34 close to the limiting plate 33, a ball 35 is arranged in the recess, the ball 35 is matched with the recess, the center of the ball 35 is located in the recess, and the ball 35 abuts against the limiting plate 33. The sliding friction between the clamping block 34 and the limiting plate 33 is converted into rolling friction by the balls 35, so that the friction force applied to the rotation of the limiting plate 33 is reduced, and the rotation of the roller 19 is facilitated.

Preferably, in order to facilitate the storage of the cable 8, the rotating assembly includes a fixing rod 36, a pulley 37 and two limiting plates 38, two ends of the fixing rod 36 are fixed on the inner walls of two sides of the storage box 7, the pulley 37 is sleeved on the fixing rod 36, the two limiting plates 38 are respectively located on two sides of the pulley 37, the limiting plates 38 are fixed on the fixing rod 36, and the cable 8 abuts against the lower side of the pulley 37. The fixed rod 36 is fixed in position, the pulley 37 can rotate on the fixed rod 36, and the rolling range of the cable 8 on the fixed rod 36 is limited by the two limiting plates 38, so that the cable 8 can move along the rotation of the pulley 37, and the cable 8 can be stored conveniently.

In this fill electric pile, supporting shoe 13 auxiliary stay rifle head 9 through among the supporting mechanism, utilize two lugs 10 to restrict the sliding distance of cable 8 on flat board 12, prevent that rifle head 9 from falling on the ground, leave the potential safety hazard, and the removal wheel 15 through pillar 14 bottom makes things convenient for supporting mechanism's removal, make supporting mechanism remove to near electric automobile and charge, moreover, when equipment restriction, it rises to drive elevating platform 16 through drive assembly, increase the distance between runner assembly and the direction subassembly, thereby in receiving most cable 8 in containing box 7, avoid cable 8 to drag on the ground and wear with ground, when needs charge, drive assembly drives elevating platform 16 and descends, reduce the distance between runner assembly and the direction subassembly, be convenient for the user to take out cable 8, conveniently charge the car.

Compared with the prior art, the new energy automobile charging pile with high safety factor and convenient use has the advantages that the gun head 9 is arranged above the flat plate 12 through the supporting mechanism, the moving distance of the line flat plate 12 on the flat plate 12 is limited by the convex block 10, the gun head 9 is prevented from falling on the ground and potential safety hazards are avoided, compared with the existing supporting mechanism, the supporting mechanism is flexible in structure, the base plate 11 and the flat plate 12 are conveniently driven to move to the vicinity of an automobile through the moving wheel 15 for charging, in addition, the lifting platform 16 is driven to lift through the driving assembly, the function of the accommodating mechanism for accommodating the cable 8 is realized, the lifting platform 16 descends during charging, the cable 8 is conveniently drawn out for charging the automobile, compared with the existing accommodating mechanism, the accommodating mechanism limits the sliding range of the cable 8 through the limiting plate 33, the cable 8 is prevented from falling off from the roller 19, and the running stability of, thereby the practicality of this electric pile of filling has been improved, carries out multistage the enlargies to the signal through first operational amplifier, second operational amplifier and third operational amplifier among the temperature measurement circuit to guarantee to the accuracy nature of signal detection, rethread adjustable resistance amplifies the regulation to the signal, prevents that the signal from spilling over, has improved temperature measurement's reliability.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
