Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and in particular relates to a wall-mounted charging pile. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. In order to reduce the occupied ground space, some charging pile equipment will hang the charging pile host on the wall with a wall mount.

[0003] However, the charging cables of existing wall-mounted charging piles have a fixed length. When the parking position is close, the distance between the vehicle charging port and the charging pile is short, resulting in poor adaptability of the charging cable length. At this time, the excess charging cable hangs long and is easily affected by external forces, resulting in insufficient stability and the risk of pedestrians tripping due to the low hanging height. In addition, when not charging, the long charging cable will cause the cable to sag and drag on the ground. Utility Model Content

[0004] The purpose of the present invention is to provide a wall-mounted charging pile to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a wall-mounted charging pile, comprising a wall mount and a wall-mounted charging pile, the wall-mounted charging pile being arranged on the wall mount, a charging cable being fixed at the lower end of the wall-mounted charging pile, a cable length self-adjusting mechanism being arranged below the wall-mounted charging pile, the cable length self-adjusting mechanism comprising a lower guide wheel, a horizontal slide rail, a guide slider and a reset spring, the horizontal slide rail being arranged below the wall-mounted charging pile, the lower guide wheel being rotatably connected between two horizontal slide rails, the guide slider being slidably connected inside the horizontal slide rail, the reset spring being arranged between the guide slider and the horizontal slide rail, an upper guide wheel being arranged behind the lower guide wheel, and a middle guide wheel being arranged below the upper guide wheel.

[0006] It should be noted in the solution that a standing bracket is vertically fixed to the lower end of the wall-mounted charging pile, and a rotation groove is provided on the surface of the standing bracket.

[0007] It is further worth mentioning that the upper guide wheel and the middle guide wheel are both rotatably connected to the rotation groove of the upright bracket, and the upper guide wheel, the middle guide wheel and the lower guide wheel are distributed at the three vertices of a triangle.

[0008] It should be further explained that an anti-slip adjustment groove is provided inside the horizontal slide rail, and the guide slider is slidably connected to the anti-slip adjustment groove of the horizontal slide rail.

[0009] As a preferred embodiment, a horizontal cross bar is horizontally fixed between the inner walls at both ends of the horizontal slide rail, and the guide slider is slidably sleeved on the horizontal cross bar.

[0010] As a preferred embodiment, the return spring is sleeved on the outside of the horizontal cross bar, one end of the return spring is fixed to the end face of the guide slider, and the other end of the return spring is fixed to the inner end wall of the horizontal slide rail.

[0011] Compared with the prior art, the wall-mounted charging pile provided by the present invention has at least the following beneficial effects:

[0012] By setting up a cable length self-adjusting mechanism, the lower guide wheel supports the charging cable to form a jacking state, and the jacking protrusion structure maintained by the lower guide wheel can cause the return spring to be squeezed under the force of the charging cable, thereby achieving the purpose of flexibly adjusting the effective use length of the charging cable. The effective use length of the charging cable can be adjusted to adapt to the different distances of the charging port of the electric vehicle.

[0013] By setting the upper guide wheel, middle guide wheel and lower guide wheel, when idle, the charging cable is wrapped around the triangular storage structure formed by the upper guide wheel, lower guide wheel and middle guide wheel. At the same time, the lower guide wheel supports the charging cable to the greatest extent so that its hem length is shorter, which can reduce the trouble of the cable drooping and dragging on the ground and being easily affected by external forces when idle.

[0022] Further as Figure 3 and Figure 4 As shown, it is worth mentioning that a stand-up bracket 5 is vertically fixed to the lower end of the wall-mounted charging pile 2 , and a rotation groove 7 is provided on the surface of the stand-up bracket 5 .

[0023] Further as Figure 3 As shown, it is worth noting that the upper guide wheel 6 and the middle guide wheel 8 are both rotatably connected to the rotation slot 7 of the upright bracket 5, and the upper guide wheel 6, the middle guide wheel 8 and the lower guide wheel 9 are distributed at the three vertices of a triangle.

[0024] This solution has the following working process: before use, the wall mount 1 is pre-fixed to the wall through the mounting hole 16 with the expansion screw. During use, the wall-mounted charging pile 2 is placed on the wall mount 1. At this time, the upright bracket 5 enters the give way groove 17 of the wall mount 1. At the same time, the adsorption magnetic strip 18 on the back of the wall-mounted charging pile 2 is magnetically adsorbed on the adsorption magnetic strip 18 on the wall mount 1 to complete the wall-hanging operation. During use, the charging cable 3 is successively passed through the upper guide wheel 6, the lower guide wheel 9 and the middle guide wheel 8, so that the lower guide wheel 9 supports the charging cable 3 to form a lifting state, and the lifting protrusion structure maintained by the lower guide wheel 9 can cause the reset spring 13 to be squeezed under the force of the charging cable 3, thereby achieving the purpose of flexibly adjusting the effective use length of the charging cable 3.

When the charging head 4 is idle, the charging line 3 is wound around the triangular storage structure formed by the upper guide wheel 6, the lower guide wheel 9 and the middle guide wheel 8. At the same time, the lower guide wheel 9 supports the charging line 3 to the greatest extent so that its hem length is shorter, which can reduce the trouble of the line drooping and dragging on the ground and being easily affected by external forces when idle.

[0030] Further as Figure 1 As shown, it is worth mentioning that the inner bottom wall of the wall mount 1 is provided with a makeshift groove 17 adapted to the upright bracket 5, the front of the wall mount 1 and the back of the wall-mounted charging pile 2 are both embedded with an adsorption magnetic strip 18, the front of the wall mount 1 is provided with a mounting hole 16, and a charging head 4 is fixed to one end of the charging cable 3.

[0031] In summary: the lower guide wheel 9 supports the charging cable 3 to form a jacking state, and the jacking protrusion structure maintained by the lower guide wheel 9 can cause the return spring 13 to be squeezed under the force of the charging cable 3, thereby achieving the purpose of flexibly adjusting the effective use length of the charging cable 3. The effective use length of the charging cable 3 can be adjusted to adapt to the different distances of the charging port of the electric vehicle; when idle, the charging cable 3 is wound on the triangular storage structure formed by the upper guide wheel 6, the lower guide wheel 9 and the middle guide wheel 8.
