Description

Technical Field

[0001] The present invention relates to a charging connection device for a three-dimensional parking garage, which is applied in the field of charging for three-dimensional parking garages. Background Art

[0002] With the popularization of electric vehicles, there is a need to charge the parked vehicles in a three-dimensional parking garage. However, it is a difficult problem to effectively and reliably charge the vehicles parked on the parking trays and moving with the parking trays in the three-dimensional parking garage. There are mainly two existing methods: First, the conductive connection of the charging pile in the three-dimensional parking garage adopts a sliding structure, and its contact points are easily worn, which affects the conductive performance. In severe cases, electrical fires may occur and the parked vehicles may be burned. Second, the method of lengthening the cable of the charging pile gun head is adopted in the three-dimensional parking garage. The moving distance of the garage position is very limited in this way, and it cannot meet the use requirements of the circulating movement of the tower-type three-dimensional parking garage. Therefore, it has become an urgent matter to provide a charging connection device for a three-dimensional parking garage that can ensure effective and reliable charging of the parked vehicles during movement in the three-dimensional parking garage. Summary of the Invention

Through the cooperation of a static conductive bus arranged along the moving track of the tray platform, and a charging connector unit with one end fixed on the tray platform and the other end movably clamped on the static conductive bus and capable of moving along the track of the static conductive bus and making rolling conductive contact with the static conductive bus, the parked vehicles in the three-dimensional parking garage can be effectively and reliably charged during movement.

[0004] The technical solution of the present invention is as follows:

[0007] The number of the static conductive bars is determined to be two or three according to whether the power supply type of the power supply device is direct current or alternating current; each static conductive bar is a flat long strip structure, and the length extension direction thereof extends along the direction parallel to the movement track of the tray platform. The row support is fixedly installed on the parking tower, and one long side of each static conductive bar is fixedly installed on the row support, and the other long side exposes the end face of the row support and extends towards the direction where the tray platform is located; the static conductive bar is made of conductive metal, and each phase of the power supply device is respectively connected to one static conductive bar to supply power to it.

The conductive output component is installed on the tray platform and is electrically connected to the charging pile fixedly installed on the corresponding tray platform.

[0009] The charging connection device of the three-dimensional parking garage of the present application arranges two or three static conductive bars respectively connected to each phase of the power supply device along the movement track of the tray platform in parallel according to the power supply type of the power supply device, installs each group of charging connectors on each tray platform, one end of each charging connector unit is fixed on the tray platform, and the other end is movably clamped on the static conductive bar.

Among them, the rolling electrical connection between the charging connector unit and the static conductive bar can effectively reduce the wear of the conductive components and improve the electrical connection reliability. If the movement track of the tray platform is a closed loop, the length extension direction of the static conductive bar is also distributed in a closed loop.

[0010] A part of the conductive output component extends out of the charging connector unit, and a connection hole for connecting the wiring head of the charging pile is provided at the extending part.

[0011] This preferred design makes the connection between the charging connector unit and the charging pile more convenient and reliable.

[0013] The preferred setting enables the charging connector unit to rotate on the three-dimensional parking garage according to the path of the power line, so as to ensure that the conductive contact points are always reliably connected during the movement of the parking platform.

[0014] The conductive connection component includes a conductive foot plate and a conductive disc. The conductive foot plate is a flat structure with the same thickness as the static conductive bar, and the two plate surfaces of the conductive foot plate are respectively arranged on the same plane as the two plate surfaces of the static conductive bar; one end of the conductive foot plate is arranged in parallel and spaced from the long side of the static conductive bar exposed from the end face of the row support, and the other end is fixedly and conductively connected perpendicular to the conductive disc, and both are made of conductive materials;

The first insulating shell covers the outside of the first disc spring, the first end face bearing spacer sleeve, the first end face bearing, the cable conductive bar, and the conductive roller disc. The cable conductive bar is made of conductive material and at least one end extends out of the first insulating shell to be conductively connected to the charging pile fixedly installed on the corresponding tray platform; the first end of the first rotating shaft passes through the first disc spring and then extends out of the top surface of the first insulating shell and is locked and fixed with a nut locking assembly. The second end of the first rotating shaft extends out of the bottom surface of the second end face bearing spacer sleeve and is locked and fixed with a nut locking assembly; the middle of the conductive disc is coaxially and rotatably connected to the first rotating shaft through the first oil-free bearing;

[0019] Each moving conductive box includes a second insulating shell, a second rotating shaft, a second disc spring, a third end face bearing spacer sleeve, a third end face bearing, a transition conductive disc, a conductive roller disc, and a second oil-free bearing; the second disc spring, the third end face bearing spacer sleeve, the transition conductive disc, and the conductive roller disc are coaxially sleeved on the outer periphery of the second rotating shaft in sequence along the axial direction of the second rotating shaft. The third end face bearing spacer sleeve is provided with an annular outer flange at one end away from the transition conductive disc. The third end face bearing is coaxially sleeved on the outer periphery of the third end face bearing spacer sleeve and is rotatably connected between the annular outer flange of the third end face bearing spacer sleeve and the transition conductive disc; the second insulating shell is locked and installed on the conductive row foot plate. The second insulating shell is open on one side facing the static conductive row and the conductive row foot plate, and covers the outside of the second disc spring, the third end face bearing spacer sleeve, the third end face bearing, the transition conductive disc, and the conductive roller disc; the outer end of the second rotating shaft passes through the second disc spring and then exposes the outer end face of the second insulating shell cover and is locked and fixed with a nut locking assembly; the transition conductive disc is rotatably sleeved on the outer periphery of the second rotating shaft through a second oil-free bearing provided in the center thereof;

[0020] Each conductive roller disc includes a disc body, a third oil-free bearing, a plurality of roller shafts, and a plurality of conductive rollers. The roller shafts are radially distributed in the disc body along different radial directions of the disc body. One or more conductive rollers are sequentially strung along the axial direction on the outer periphery of each roller shaft. The disc body center of the conductive roller disc of the moving conductive box is rotatably sleeved on the outer periphery of the second rotating shaft through a third oil-free bearing, and the disc body center of the conductive roller disc of the static conductive box is rotatably sleeved on the outer periphery of the first rotating shaft through a third oil-free bearing; the rolling surfaces of the conductive rollers of the conductive roller disc of each moving conductive box partially expose the opening of the second insulating shell and press on the same side plate surface of the static conductive row and the cable conductive row; the transition conductive disc and the conductive rollers are made of conductive materials; the rolling surfaces of the conductive rollers of the conductive roller disc of each moving conductive box partially expose the disc body and are in conductive rolling contact with the transition conductive disc, and the rolling surfaces of the conductive rollers of the conductive roller disc of the static conductive box partially expose the disc body and are in conductive rolling contact with the conductive row disc and the cable conductive row.

[0021] The preferred solution specially designs a charging connector structure assembled by two moving conductive boxes and one static conductive box. When the static conductive box moves with the tray platform, the conductive roller disc of the static conductive box rotates around the same rotating shaft under the action of friction force. When passing through the annular turning point, the moving conductive box drives the conductive connection component to rotate around the first rotating shaft along the path of the static conductive row, realizing the turning process. The specific current path is as follows: power supply device → static conductive row → conductive rollers of the conductive roller disc of the moving conductive box → transition conductive disc → conductive rollers of the conductive roller disc of the moving conductive box → conductive row foot plate → conductive row disc → conductive rollers of the conductive roller disc of the moving conductive box → cable conductive row → charging pile → parked vehicle. The moving conductive box makes rolling contact with the static conductive row through conductive rollers, which can effectively reduce wear and improve conductive reliability. The number of conductive rollers can be increased or decreased according to the load size to ensure the number of effective contact points at the moving contact part. The contact pressure between the conductive roller and the static conductive row is provided by the second disc spring, avoiding the disadvantage of poor contact caused by wear in sliding connection. Moreover, the setting of the conductive rollers in the static conductive box enables the cable conductive row to rotate flexibly to adapt to the path of the power supply line when the tray platform moves, thus meeting the requirement that the conductive contact points are always reliably connected during the movement of the tray platform. The use of the first end face bearing, the second end face bearing, and the third end face bearing can reduce the friction force.

[0022] Except that the static conductive row, the conductive connection component, the cable conductive row, the transition conductive disc, and each conductive roller are made of conductive metal, other components are made of insulating materials.

[0023] The static conductive box further includes at least one guiding column arranged parallel to the first rotating shaft. One end of the guiding column penetrates through and is fixedly connected to the first insulating shell, and the other end is a two-layer stepped structure. The lower step of this end penetrates through the cable conductive row from top to bottom in a movable manner, the diameter of the upper step is larger than that of the lower step, and there is a gap between the bottom surface of the upper step and the top surface of the cable conductive row.

[0024] The guiding column fixes the first insulating shell and the cable conductive row together, which can not only prevent the cable conductive row from rotating but also ensure that the cable conductive row can slightly move axially along the first rotating shaft according to the force condition of the first disc spring.

[0025] Each set of nut locking components includes a pair of nuts, spring washers, and flat washers arranged in sequence from the end face inward along the axial direction of each rotating shaft.

[0026] The preferred nut locking component structure makes the fixing effect of the nut better.

[0027] The roller shafts are the first roller shaft and the second roller shaft that are alternately distributed at intervals along the circumferential direction. The number of conductive rollers sleeved on the first roller shaft is 3, and the number of conductive rollers sleeved on the second roller shaft is 2.

[0028] The preferred conductive roller disc has a low cost and can meet the basic requirements.

[0029] The conductive row footplate is arranged overlapping with the central axis of the conductive row disc on the same plane. A receiving hole is provided at the top of the conductive row footplate, and the second end portion of the first rotating shaft, the second end face bearing, and the second end face bearing spacer sleeve are all located within the receiving hole.

[0030] The preferred structure makes the overall structure of the charging connector more firm and reasonable.

[0031] There are two guiding columns.

[0032] The preferred number of guiding columns can increase the stability of the cable conductive row fixation.

[0034] 1) The charging connection device of the three-dimensional parking garage in this application is provided with multiple static conductive rows respectively connected to each phase of the power supply device.
