Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings and embodiments thereof.

Example 1:

referring to fig. 1 to 20, the present embodiment provides a high-current wire arranging connection device, which includes a first connection arm 10 and a second connection arm 20, where the first connection arm 10 and the second connection arm 20 respectively have a first hinge end 11 and a second hinge end 21, and the first connection arm 10 and the second connection arm 20 are hinged to each other through the first hinge end 11 and the second hinge end 21;

the other end of the first connecting arm 10 opposite to the first hinged end 11 is provided with a rotating connecting part 13 connected with the charging pile 01;

the other end of the second connecting arm 20 opposite to the second hinged end 21 is provided with a charging connecting end 23 connected with the large-flow wire 02;

the thick and hard and heavy current wire can not be like the control that the ordinary wire of removal can generally follow one's mind at the in-process that removes, need both hands to hold the one end and the middle part position of heavy current wire, just can avoid the middle part of heavy current wire to drag ground when removing the heavy current wire, and the friction between the ground causes the damage, nevertheless set up the electric pile 01 that fills in public parking area, part user directly drags charging gun 03 and removes the heavy current wire when using, the middle part that leads to the heavy current wire is dirty, the user of back also is more reluctant to mention the wire when removing the heavy current wire.

According to the technical scheme provided by the invention, the large-current lead is connected to the second connecting arm 20, the large-current lead is driven to move along with the second connecting arm 20, the middle part of the large-current lead can be connected with the charging connecting end 23 of the second connecting arm 20, when the charging is not carried out, the charging gun 03 is inserted into the charging pile 01, and the large-current charging middle part is connected with the charging connecting end 23. When needing to charge, a user only needs to hold the charging gun 03 to drag the large-flow wire 02, the middle part of the large-flow wire 02 is connected with the charging connecting end 23 of the second connecting arm 20, the charging connecting end 23 is far away from the ground, when the charging gun 03 is held to move, the middle part of the large-flow wire 02 can not be in contact with the ground, and fouling when dragging relative to the ground can not occur.

First linking arm 10, second linking arm 20 and to the second linking arm 20 carry out the electric pile that fills that supports and have three rotation between articulated setting, make the charging connection end 23 of second linking arm 20 can move to the farther place from filling electric pile, do not restrict the removal of large-traffic wire that charges, avoided the ground that drags of large-traffic wire 02 again.

Wherein, the first connecting arm 10 is provided with a synchronous winch 30, the synchronous winch 30 is wound with a first control wire 31 and a second control wire 32, and the winding directions of the first control wire 31 and the second control wire 32 are the same; the free end of the first control line 31 is fixedly connected with the charging pile; the free end of the second control wire 32 is fixedly connected with the second connecting arm 20; the winding device further comprises a winding assembly 33, wherein the winding assembly 33 is connected with the synchronous winch 30 and drives the synchronous winch 30 to rotate along the winding direction.

It should be noted that the free end of the control wire refers to the end which is not fixed by the synchronizing winch 30 and is free relative to the end which starts to wind on the synchronizing winch 30 after being fixed.

The first control wire 31 and the second control wire 32 are wound on the synchronous winch 30 together, when the synchronous winch 30 rotates, the first control wire 31 and the second control wire 32 are simultaneously wound or unwound, and since the free ends of the first control wire 31 and the second control wire 32 are respectively connected with the charging pile and the second connecting arm 20, when the angle between the first connecting arm 10 and the second connecting arm 20 is changed, the angle between the first connecting arm 10 and the charging pile is changed simultaneously, and vice versa.

Make charging connection end 23 can move along a comparatively gentle fixed track when removing to guaranteed that this removal track has certain distance all the time with between the ground, avoided dragging ground at the in-process large-traffic wire that removes.

The winding assembly 33 always provides a force for winding the first control line 31 and the second control line 32, so that the first connecting arm 10 and the second connecting arm 20 can be folded to a state perpendicular to the height direction of the charging pile without interference of an external force.

When the charging gun is used, a user pulls the large-flow wire to move, the connecting arm is pulled open by overcoming the winding force of the winding assembly 33, when the connecting arm is folded, the limitation on the rotation of the connecting arm is only needed to be removed (for example, the charging gun 03 is pulled out from a charging port of an automobile), the connecting arm is automatically folded under the driving of the winding assembly 33, and then the charging gun 03 is hung.

Example 2:

The mode that the charging connecting part is connected with the middle part of the large-flow wire already avoids the pollution of the large-flow wire caused by the contact of the large-flow wire with the ground in the dragging process. But because the position at the one end middle part of large-traffic direction has been restricted by charging connection end 23, and large-traffic wire is comparatively thick and hard, when inserting the removal electric pile of filling back with electric gun 03, need certain deformation bending of large-traffic wire, just can insert electric gun 03 back into and fill electric pile, to some user that strength is less, accomplish this step and probably be more labourious.

In the technical solution provided in this embodiment, a lifting rope 14 is connected to the hinged position of the first connecting arm 10 and the second connecting arm 20, the lifting rope 14 is used to connect the middle portion of the large-flow wire, and the charging connection portion of the second connecting arm 20 is used to connect one end of the large-flow wire close to the charging gun 03. The large flow wire is spirally hung at the lower part of the connecting arm, as shown in fig. 3, when charging is needed, the charging connecting end 23 is moved to the charging position of the vehicle, and the large flow wire can be stretched like a spring and can be contracted when being folded. The charging gun 03 can be free from being fixed after being folded, or the position of the charging pile can be fixed slightly when the connecting arm is folded.

The user then only needs to pull or push back the connecting arm and insert/remove the charging gun in the vehicle without having to pull the large flow wire.
