DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0035] Referring to Figure 1 , Figure 2 , Figure 4 andFigure 6 The application provides a new energy charging device facilitating automobile parking. After a vehicle stops at a parking space, the charging pile and the charging wire can be adaptively adjusted according to the position of the vehicle charging interface, so as to reduce the friction between the charging wire and the vehicle. The device comprises a mounting base plate 1 and a position blocking unlocking mechanism. The mounting base plate 1 is provided with an adjustable charging mechanism 2. The charging mechanism 2 comprises a bottom rail 21, a vertical charging pile 22 and a lead assembly 23. The bottom rail 21 is arranged on the top surface of the mounting base plate 1. The vertical charging pile 22 is vertically slidably arranged on the bottom rail 21. The lead assembly 23 is arranged on one side of the vertical charging pile 22. The connecting wire of the vertical charging pile 22 passes through the lead assembly 23.

[0036] The position blocking unlocking mechanism comprises a position blocking backing plate 3, a linkage 4 and a pile body locking assembly 5. The position blocking backing plate 3 is arranged on one side of the mounting base plate 1. The linkage 4 is arranged on the top surface of the mounting base plate 1 and located between the position blocking backing plate 3 and the charging mechanism 2. One end of the pile body locking assembly 5 is connected with the linkage 4, so that the position blocking backing plate 3 and the pile body locking assembly 5 are linked.

[0037] The vertical charging pile 22 comprises a sliding bottom table 221 slidably arranged on the bottom rail 21. The pile body locking assembly 5 acts on the sliding bottom table 221 and forms a locking. When the position blocking backing plate 3 and the pile body locking assembly 5 are linked, an unlocking effect on the sliding bottom table 221 is formed.

[0038] The distance between the position blocking backing plate 3 and the vertical charging pile 22 is greater than the distance between the rear wheel of the new energy vehicle and the tail of the vehicle. When the rear wheel of the vehicle contacts the position blocking backing plate 3, the tail of the vehicle is still at a certain distance from the vertical charging pile 22.

[0039] Referring to FIGS. 1, 2 and 3, Figure 4 and Figure 6 The linkage 4 comprises a connecting piece 41, a limiting backing plate 42 and a connecting sliding rod 43. The limiting backing plate 42 is arranged above the mounting base plate 1. The connecting sliding rod 43 is slidably arranged along the plate body of the limiting backing plate 42. One end of the connecting sliding rod 43 penetrates through the bottom rail 21 and is connected with the pile body locking assembly 5. The connecting piece 41 is arranged at the other end of the connecting sliding rod 43. The connecting piece 41 is connected with the position blocking backing plate 3.

[0040] The connecting piece 41 and the connecting sliding rod 43 are in one-to-one correspondence. A plurality of sets of the connecting piece 41 and the connecting sliding rod 43 are arranged on the limiting backing plate 42. The plurality of sets of the connecting piece 41 and the connecting sliding rod 43 can form sufficient supporting force on the position blocking backing plate 3.

[0041] As shown in FIGS. 4 and 5, Figure 6 and Figure 8As shown, the pile locking assembly 5 includes a synchronous locking block 51 and an elastic reset member 52 connected to the connecting slide rod 43. The elastic reset member 52 is disposed between the synchronous locking block 51 and the bottom rail 21, so that the synchronous locking block 51 maintains a tendency to slide towards the bottom rail 21. A locking groove is provided on the side of the sliding base 221 near the synchronous locking block 51. Under the action of the elastic reset member 52, the synchronous locking block 51 is inserted into the inner side of the locking groove, thereby locking the sliding base 221.

[0042] See Figure 5 , Figure 6 and Figure 8 As shown, the synchronous locking block 51 is an L-shaped card block, and the edge of the block into which the synchronous locking block 51 is inserted is an arc edge.

[0043] It should be clarified that when the end of the L-shaped synchronous locking block 51 is inserted into the locking groove of the sliding base 221, its insertion depth is short. This allows the wheel to rotate downwards with a small downward rotation amplitude when it squeezes the stop plate 3, which is enough to drive the synchronous locking block 51 out of the locking groove of the sliding base 221 and complete the unlocking of the sliding base 221.

[0044] See Figure 4 and Figure 6 As shown, the stop pad 3 is an arc-shaped plate, and both ends are rotatably installed at the edge of the mounting base plate 1. The bottom end of the stop pad 3 is provided with a pop-out component for buffering and popping out. Since the mounting base plate 1 is set in contact with the ground of the parking space, the stop pad 3 will be located in the rear half of the parking space, acting as a damper. When the rear wheel of the vehicle squeezes the stop pad 3, the stop pad 3 will rotate downward and squeeze the pop-out component. When the vehicle leaves, the stop pad 3 will bounce up under the action of the pop-out component.

[0045] When the stop plate 3 rotates downwards, it can push the connecting slide rod 43 to slide, and drive the synchronous locking block 51 on the other side of the connecting slide rod 43 to leave the locking groove of the sliding base 221, thereby releasing the lock on the vertical charging pile 22. At this time, the vertical charging pile 22 can be pushed, so that the sliding base 221 slides on the bottom rail 21, thereby adjusting the position of the vertical charging pile 22 to adapt to the position of the vehicle charging port, thereby reducing the need for charging.

[0046] Furthermore, the synchronous locking block 51 will only be triggered to leave the locking groove of the sliding base 221 when the rear wheel of the vehicle is pressed against the blocking pad 3, thereby unlocking the vehicle. In other words, the position of the vertical charging pile 22 can only be moved and adjusted for charging when the vehicle enters the parking space and is in a ready-to-charge state.

[0047] like Figure 1 and Figure 2 As shown, the surface of the resistive pad 3 is provided with raised strips to increase friction.

[0048] In order to keep the charging pile and the external line straight when adjusting the position of the charging pile, prevent the line from falling to the ground with the movement of the charging pile, and affect the use of the charging pile, see Figure 6 and Figure 7 The lead assembly 23 is provided with a lifting slider 231 and a lead rotating wheel 232, and the vertical charging pile 22 further comprises a supporting column 222, which is provided with a vertical sliding groove on one side, and the lifting slider 231 is vertically installed inside the sliding groove, and the lead rotating wheel 232 is rotatably installed outside the lifting slider 231, and the lead rotating wheel 232 is attached to the supporting column 222, and the connecting line of the vertical charging pile 22 passes through the lead rotating wheel 232 and is connected to the external line.

[0049] The sliding groove inside the supporting column 222 is provided with a guide vertical rod for guiding, and the guide vertical rod penetrates the block of the lifting slider 231.

[0050] Referring to Figure 3 and Figure 7 The sliding base 221 is provided with a traction member 6 on one side for pulling the sliding base 221 to move, and the traction member 6 is a device that generates traction force by rotating the bottom rail 21 with the motor-driven rotating wheel, and the traction member 6 is built-in with a controller for controlling the motor, and the traction member 6 is provided with a control button for controlling the operation of the motor, so as to control the operation of the traction member 6 and pull the sliding base 221 to slide to the fixed position, and after unlocking the sliding base 221, as shown in Figure 5 the control button above the traction member 6 can be used to control the operation of the traction member 6, so as to pull the sliding base 221 to slide to the left, right or middle on the bottom rail 21, and the position of the sliding base 221 and the vertical charging pile 22 can be adjusted according to the position of the charging interface of the charging vehicle, so that the vertical charging pile 22 is close to the interface side, facilitating plugging and charging without pulling the charging line around the vehicle, reducing the friction between the charging line and the vehicle.

[0051] In addition, when the wheel leaves the blocking pad 3, the synchronous locking block 51 will be inserted into the locking groove of the sliding base 221 again under the action of the elastic reset member 52, as shown in Figure 5 The insertion locking part of the synchronous locking block 51 is a semicircular plate, and when the sliding base 221 moves towards the direction opposite to the arc edge, it can extrude the semicircular plate outside to continue to move, and when the sliding base 221 moves towards the direction opposite to the arc edge, it will be limited by the straight edge of the semicircular plate and cannot slide through, so as to make the sliding base 221 present a one-way movement effect on the bottom rail 21, and through the operation of the traction member 6, after the vehicle leaves, the sliding base 221 is driven to move to the edge of the bottom rail 21, so that the vertical charging pile 22 is located at the corner of the parking space, without occupying too much space of the parking space.

[0052] The lead rotating wheel 232 includes a rotating shaft and a winding wheel arranged at the rotating end portion, and the winding wheel part of the lead rotating wheel 232 is adapted to the width of the connecting wire of the vertical charging pile 22.

[0053] It needs to be clear that when the vertical charging pile 22 slides on the bottom rail 21 with the sliding base 221, the circumscribed wire body of the vertical charging pile 22 will be pulled, at this time, through the up and down movement of the lead rotating wheel 232 in the sliding groove of the supporting column 222, the lead rotating wheel 232 can always rotate around the middle part of the circumscribed wire body, so that the circumscribed wire body remains in a straight state, preventing the circumscribed wire body from being loose and falling after the vertical charging pile 22 moves, and increasing the safety of the circumscribed wire body.

[0054] Working principle: the whole device is installed at the rear side of the parking space through the installation base plate 1, and the blocking pad 3 is in the rear half of the parking space. When the vehicle is parked in the parking space, the wheels of the vehicle will press the blocking pad 3, so that the blocking pad 3 rotates downward and pushes the connecting sliding rod 43 to slide through the connecting effect of the connecting piece 41. At this time, the synchronous locking block 51 on the other side of the connecting sliding rod 43 will leave the locking groove of the sliding base 221, so as to release the locking of the vertical charging pile 22. At this time, the position of the vertical charging pile 22 on the bottom rail 21 can be adjusted. The rotating wheel part of the traction piece 6 is attached to the surface of the bottom rail 21 to rotate and generate traction, so as to pull the sliding base 221 and the whole vertical charging pile 22 to move on the bottom rail 21, so that the user can adjust the position of the vertical charging pile 22 at the rear of the parking space according to the position of the vehicle charging interface, adapt to the distribution of different new energy vehicle charging ports, avoid winding the wire around the vehicle during connection, prevent the scratch caused by pulling the wire around the vehicle, and complete the charging. When the vehicle drives away from the parking space, the tire of the vehicle leaves the blocking pad 3 at this time. Under the action of the elastic reset piece 52, the synchronous locking block 51 and the connecting sliding rod 43 are reset, so that the synchronous locking block 51 is inserted into the locking groove of the sliding base 221 again. Through the work of the traction piece 6, the sliding base 221 is driven to move to the edge of the bottom rail 21, so that the vertical charging pile 22 is located at the corner of the parking space, without occupying too much space of the parking space. The limiting effect of the semicircular plate at the end of the synchronous locking block 51 prevents the sliding base 221 from sliding reversely, so as to lock the position of the sliding base 221 and the vertical charging pile 22.

Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
