When the lifting table plate ascends, the charging wire is wound by the wire winding shaft, when the lifting table plate descends, the charging wire is released by the wire winding shaft, the length of the charging wire wound by the wire winding shaft is the same as the ascending distance of the lifting table plate in unit time, and the length of the charging wire released by the wire winding shaft is the same as the descending distance of the lifting table plate in unit time.

In the current society, electric automobile use volume is the rapid growth, and one problem that stereo garage often meets at present is: charging of the electric automobile requires manual insertion of a charging plug of a charging pile into the electric automobile, and after charging is completed, the charging plug needs to be pulled out manually. When the stereo garage is used, except for a ground layer (namely a vehicle storage and taking layer), the stereo garage is unmanned (a user cannot go to other layers along with the vehicle), so that an electric vehicle parked on the non-ground layer (the vehicle storage and taking layer) cannot be charged. In the present embodiment, the above problems are reasonably and effectively solved, and the details are described below.

When the electric automobile needs to be powered off (needs to be charged), the lifting platform plate descends to a ground floor, the driven gear is driven by the lifting mechanism to rotate in the descending process, so that the charging wire is continuously released to adapt to the descending of the lifting platform plate, then the electric automobile can be driven onto the lifting platform plate, then the charging plug can be inserted into the charging socket of the electric automobile, and a user leaves the lifting platform plate. Then, the lifting mechanism drives the lifting table plate to ascend and reset, and in the ascending process, the driven gear is driven by the lifting mechanism to rotate, so that the charging wire is continuously wound to adapt to the ascending of the lifting table plate. It should be noted that in this embodiment, the length of the charging wire between the positioning sleeve and the charging plug should not be too short, and a certain length should be left to adapt to the charging operation, which is 1 to 3 meters conventionally. While a conventional vehicle or an electric vehicle that does not require recharging may be parked on the ground below the lift table (with the lift table in the raised position rather than the ground level position).

The lifting bedplate is provided with an ascending platform 22, the ascending platform and the main upright post are respectively arranged at two opposite sides of the lifting bedplate, the top surface of the ascending platform is an inclined surface, and one side of the top surface of the ascending platform, which is adjacent to the lifting bedplate, is higher than one side of the top surface of the ascending platform, which is far away from the lifting bedplate. The ascending platform can assist the electric automobile to open the lifting platform plate more conveniently.

Example 2: based on embodiment 1, as shown in fig. 4 to 7,

the main upright post is provided with an upper sleeve 11, a traverse cylinder 12 and a lower sleeve 13, the upper sleeve, the traverse cylinder and the lower sleeve are all vertically arranged, a traverse inner piston 121 matched with the traverse cylinder in a sliding and sealing way is arranged in the traverse cylinder, the traverse cylinder is divided into a traverse outer cavity 12a and a traverse inner cavity 12b by the traverse inner piston, the traverse outer cavity is communicated with the atmosphere, a traverse piston rod 122 penetrating through the traverse inner cavity is arranged on the traverse inner piston and matched with the traverse cylinder in a sliding and sealing way, a middle sleeve 14 is arranged on the traverse piston rod, the traverse outer cavity, the traverse inner cavity and the middle sleeve are sequentially arranged along the axial direction of the traverse piston rod, a charging wire sequentially penetrates through the upper sleeve, the middle sleeve, the lower sleeve and the positioning sleeve, the upper sleeve, the lower sleeve and the positioning sleeve are coaxially arranged, a traverse outer limiting body 123 used for contacting with the traverse inner piston is arranged in, the lifting bedplate is provided with a bedplate groove with an opening on the top surface of the lifting bedplate, the bedplate groove is provided with a wheel pressing plate 23 capable of moving up and down along the bedplate groove and a pressed cylinder body 24 fixed in the bedplate groove, the pressed cylinder body is internally provided with a pressed inner piston 241 matched with the pressed cylinder body in a sliding and sealing way, the pressed cylinder body is divided into a pressed lower cavity 24a and a pressed upper cavity 24b by the pressed inner piston, the pressed upper cavity is communicated with the atmosphere, the pressed inner piston is provided with a plurality of pressed piston rods 242 penetrating through the pressed upper cavity, the upper ends of the pressed piston rods are connected with the wheel pressing plate, the pressed lower cavity is internally provided with a plurality of pressed springs 243, the upper ends of the pressed springs are connected with the pressed inner piston, the lower ends of the pressed springs are connected with the; in the vertical direction: the wheel pressing plate, the pressed upper cavity and the pressed lower cavity are sequentially arranged from top to bottom, the upper sleeve, the middle sleeve, the lower sleeve and the positioning sleeve are sequentially arranged from top to bottom, and the positioning sleeve, the limiting pull ring and the charging plug are sequentially contacted from top to bottom; in the axial direction of the traverse piston rod: the upper sleeve is arranged between the traversing cylinder body and the middle sleeve.

When the piston in the transverse moving contacts the limiting body in the transverse moving: the length of the charging wire between the upper sleeve and the lower sleeve is X meters, the distance between the upper sleeve and the lower sleeve is Y meters, the sum of X minus Y is equal to Z, and Z is 1 to 3.

When the inner piston in transverse movement contacts the outer transverse movement limiting body: the top surface of the wheel pressing plate is flush with the top surface of the lifting bedplate, the lifting bedplate is in contact with the pressurized cylinder body, and the upper sleeve is coaxial with the middle sleeve.

In embodiment 1, although the adaptive adjustment of the charging wire is achieved, the foregoing also explicitly indicates: in embodiment 1, the length of the charging wire between the positioning sleeve and the charging plug is not too short, and a certain length must be left in order to accommodate the charging operation, conventionally, 1 to 3 meters is preferable. This leads to a problem: the charging wire (the charging wire between the positioning sleeve and the charging plug) is always uncontrolled, and the charging wire is easy to collide with an electric automobile (the electric automobile collides with the charging plug and the charging wire when the lifting platform plate is opened), and is pressed by the electric automobile (the distance between the positioning sleeve and the lifting platform plate is smaller than the length of the charging wire between the positioning sleeve and the charging plug, so that the charging plug is dragged on the lifting platform plate, and the charging plug can be pressed by the lifting platform plate when the electric automobile is opened), and the like.

In this embodiment, at ordinary times, the positioning sleeve, the limiting pull ring and the charging plug are sequentially contacted from top to bottom, so that the above problem does not exist. Moreover, since the positioning sleeve, the limiting pull ring and the charging plug are sequentially contacted from top to bottom, the charging wire between the winding spool and the positioning sleeve is tensioned (otherwise, the limiting pull ring cannot maintain the state of contacting the positioning sleeve due to gravity). When the electric automobile needs to be powered off and charged, the lifting platform descends to the ground floor, the driven gear is driven by the lifting mechanism to rotate in the descending process, so that the charging wire is continuously released to adapt to the descending of the lifting bedplate, meanwhile, the positioning sleeve continuously pulls down the charging plug, so that the charging wire (the charging wire between the wire winding shaft and the positioning sleeve) is always kept tensioned, then the electric automobile can be driven to the lifting bedplate, the front wheel or the rear wheel of the wheel is pressed onto the wheel pressing plate, the wheel pressing plate moves downwards until contacting the pressed cylinder body, the pressed inner piston moves downwards, a part of gas in the pressed lower cavity enters the transverse moving inner cavity, the transverse moving inner piston, the transverse moving piston rod and the middle sleeve move together until the transverse moving inner piston contacts the transverse moving outer limiting body, and at the moment, the upper sleeve is coaxial. Therefore, the charging wire between the upper sleeve and the lower sleeve is tensioned, and becomes loose, which means that a part of 'margin' is added. The user can hand charging plug pulling charging wire, and above-mentioned this part "surplus" can be pulled out to the charging wire between lower sleeve pipe and the charging plug will have certain length (more suitable length is 1 to 3 meters), thereby can be smoothly with the charging plug insert electric automobile's charging socket on, the user leaves the lift platen. After that, the lifting platform plate can be lifted normally, because the 'allowance' will not disappear as long as the electric automobile is not separated from the lifting platform plate (the wheels are not separated from the wheel pressing plate), and the lifting of the lifting platform plate can be still smoothly carried out.

When the electric automobile needs to be taken away, the lifting platform plate descends to the ground floor, the charging plug is pulled out, the electric automobile is driven away, the wheel pressing plate is released, under the action of the pressure spring, the wheel pressing plate ascends to reset, a part of gas in the transverse moving inner cavity enters the pressure lower cavity, the transverse moving inner piston, the transverse moving piston rod and the middle sleeve move together to reset, the transverse moving inner piston contacts the transverse moving inner limiting body again, the charging wire between the upper sleeve and the lower sleeve is tensioned again, the allowance disappears, and the electric automobile returns to the state that the positioning sleeve, the limiting pull ring and the charging plug are sequentially contacted from top to bottom.
