Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a charging pile that is easy to retract its cable. Background Technology

[0002] Charging piles can be fixed to the ground or walls and installed in public buildings, residential parking lots, or charging stations. They can charge various models of electric vehicles according to different voltage levels. Charging piles generally provide two charging methods: regular charging and fast charging.

[0003] According to a public notice regarding a convenient DC charging pile for electric vehicles (Announcement No.: CN220199108U), the aforementioned application includes a flexible connecting tube and a fixed suction cup. When charging a vehicle using the charging connector, the suction cup can be attached to any position on the vehicle without causing the charging connector and power cord to bend and damage the power cord during charging.

[0004] However, when using the above-mentioned devices, the charging head's connecting cable cannot be guaranteed to be perpendicular to the outer surface of the charging pile when it is pulled out. If the car's charging port is at an angle to the charging pile, the charging head and connecting cable need to be pulled outwards and bent at a certain angle, which can easily cause friction damage between the charging head's connecting cable and the charging pile's outer shell, affecting the safety and lifespan of the charging cable. In view of this, we propose a charging pile that is easy to retract the cable. Utility Model Content

[0005] The purpose of this invention is to provide a charging station that is easy to retract its cable, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a charging pile with convenient cable retraction, comprising a housing, an electric wire fixedly connected to the inner wall of the housing, a charging head fixedly connected to the end of the electric wire, a guide wheel rotatably mounted on the inner wall of the housing, and a torsion assembly provided inside the housing;

[0007] The torsion assembly includes an annular rail, which is fixedly installed on the inner wall of the housing. An arc-shaped rod is fixedly installed on the inner wall of the annular rail. A slider is slidably installed through the outer wall of the arc-shaped rod. An arc-shaped spring is fixedly connected to the side wall of the slider. A torsion wheel is rotatably installed on the outer wall of the slider near the center of the annular rail. An arc-shaped groove is formed on the arc-shaped outer wall of the torsion wheel. An L-shaped block is slidably installed on the inner wall of the torsion wheel. A small spring is fixedly connected to the side wall of the L-shaped block. A protrusion is fixedly installed on the side of the L-shaped block near the arc-shaped groove. A disc is fixedly connected to the outer wall of the slider near the center of the annular rail. A fan-shaped groove is formed on the outer wall of the disc near the torsion wheel.

[0008] Preferably, the inner wall of the front side of the housing has a shrinkage cavity with a width adapted to the width of the annular rail, so as to facilitate the storage and placement of the twisting assembly and the wires.

[0009] Preferably, there are two sets of sliders and arc rods, and the two sets of sliders and arc rods are arranged mirror images of each other on both sides of the annular rail to ensure that the torsion wheel is placed horizontally.

[0010] Preferably, there are two sets of L-shaped blocks, and both sets of L-shaped blocks are arranged in a circular array on the inner wall of the torsion wheel. The two sets of L-shaped blocks are respectively arranged on both sides of the vertical central axis of the torsion wheel, and the two sets of L-shaped blocks are staggered, thereby improving the clamping and stabilizing effect of the L-shaped blocks and protrusions on the wires in contact with the arc groove.

[0011] Preferably, the side of the torsion wheel is provided with a through hole that matches the end of the L-shaped block, so that the end of the L-shaped block can contact the side wall of the disk through the through hole.

[0012] Preferably, a clamping assembly is provided on the outer surface of the protrusion, the clamping assembly includes a bending band, the bending band is fixedly installed on the outer surface of the protrusion on the side away from the center of the torsion wheel, and the outer wall of the end of the bending band is provided with a wave groove.

[0013] Preferably, the bending strip is arc-shaped, and the end of the bending strip is inclined toward the center of the arc groove, so that when the protrusion comes into contact with the surface of the wire along with the L-shaped block, it can better clamp and position the outer sheath of the wire.

[0014] Compared with the prior art, this utility model provides a charging station that is easy to retract its cable, and has the following beneficial effects:

[0015] 1. This convenient charging station features a torsion assembly. The pull of the wire on the arc-shaped groove causes the torsion wheel to rotate at a certain angle along the inner wall of the circular track. As the torsion wheel rotates, the end of the L-shaped block enters the fan-shaped groove through a perforation inside the wheel. The protrusions, staggered left and right within the arc-shaped groove, ensure the wire is positioned on the torsion wheel. Even if the wire twists horizontally, its positioning and protection are maintained, preventing wear on the wire's outer surface and ensuring its safety and lifespan.

[0016] 2. This convenient charging station features a clamping component that ensures good anti-slip properties at various points when the cable comes into contact with the end of the bending strip. This guarantees stable clamping of the cable and prevents damage or detachment during dragging or bending, thus ensuring the normal and stable use of the cable and charging head.

[0025] like Figures 1-7 As shown, this utility model provides a technical solution: a charging pile with convenient cable retraction, including a housing 1, an electric wire 2 fixedly connected to the inner wall of the housing 1, a charging head 3 fixedly connected to the end of the electric wire 2, a guide wheel 4 rotatably installed on the inner wall of the housing 1, and a torsion assembly 5 provided inside the housing 1. The torsion assembly 5 includes an annular rail 51, an arc rod 53, a slider 52, an arc spring 54, a torsion wheel 55, an arc groove 56, an L-shaped block 57, a small spring 58, a protrusion 59, a disc 510, and a fan-shaped groove 511.

[0026] In one embodiment of this utility model, an annular rail 51 is fixedly installed on the inner wall of the housing 1. An arc-shaped rod 53 is fixedly installed on the inner wall of the annular rail 51. A slider 52 is slidably installed through the outer wall of the arc-shaped rod 53. An arc-shaped spring 54 is fixedly connected to the side wall of the slider 52. A torsion wheel 55 is rotatably installed on the outer wall of the slider 52 near the center of the annular rail 51. An arc-shaped groove 56 is opened on the arc-shaped outer wall of the torsion wheel 55. An L-shaped block 57 is slidably installed on the inner wall of the torsion wheel 55. A small spring 58 is fixedly connected to the side wall of the L-shaped block 57. A protrusion 59 is fixedly installed on the side of the L-shaped block 57 near the arc-shaped groove 56. A disc 510 is fixedly connected to the outer wall of the slider 52 near the center of the annular rail 51. A fan-shaped groove 511 is opened on the outer wall of the disc 510 near the torsion wheel 55.

[0027] Furthermore, there are two sets of charging heads 3, and the two sets of charging heads 3 are symmetrically arranged with the vertical central axis of the housing 1 as the axis of symmetry, so that one charging pile can charge two electrical devices at the same time. At the same time, the inner wall of the front of the housing 1 has a shrinkage cavity with a width that matches the width of the annular rail 51, so as to facilitate the storage and placement of the torsion assembly 5 and the wire 2. Specifically, the guide wheel 4 is connected to the wire 2 through a transmission, so that the guide wheel 4 and the torsion wheel 55 can cooperate with each other to guide and store the wire 2.

[0028] Meanwhile, there are two sets of sliders 52 and arc rods 53, and the two sets of sliders 52 and arc rods 53 are mirror images of each other on both sides of the annular rail 51 to ensure that the torsion wheel 55 is placed horizontally. Specifically, the inner wall of the annular rail 51 has an arc cavity of a size that matches the slider 52 to facilitate the horizontal sliding of the slider 52. At the same time, the two ends of the arc spring 54 are fixedly connected to the side wall of the slider 52 and the inner wall of the end of the arc cavity, respectively. The arc spring 54 is sleeved on the outside of the arc rod 53 so that when the slider 52 moves along the outer surface of the arc rod 53 in an arc, it always has a tendency to move in the opposite direction to achieve a reset.

[0029] In addition, two sets of L-shaped blocks 57 are provided, and both sets of L-shaped blocks 57 are arranged in a circumferential array on the inner wall of the torsion wheel 55. The two sets of L-shaped blocks 57 are respectively located on both sides of the vertical central axis of the torsion wheel 55, and the two sets of L-shaped blocks 57 are staggered, thereby improving the clamping and stabilizing effect of the L-shaped blocks 57 and the protrusions 59 on the wires 2 in contact with the arc grooves 56. At the same time, the two ends of the small springs 58 are fixedly connected to the L-shaped blocks 57 and the inner wall of the torsion wheel 55, respectively. The side of the torsion wheel 55 has through holes that are adapted to the ends of the L-shaped blocks 57, so that the ends of the L-shaped blocks 57 can pass through. The perforation contacts the side wall of the disc 510. Specifically, there are two sets of fan-shaped grooves 511, which are respectively located on the top of the disc 510 and the bottom of the disc 510 near the center of the housing 1. This allows the end of the L-shaped block 57 to be affected by the side wall of the disc 510 in the contact area between the wire 2 and the torsion wheel 55 during use, thereby clamping the surface of the wire 2 in the arc groove 56. This prevents the wire 2 from slipping off the surface of the torsion wheel 55, which would affect the stable winding and unwinding of the wire 2 and thus the sustainable use of the charging head 3.

[0030] In an embodiment of this utility model, a clamping component 6 is provided on the outer surface of the protrusion 59. The clamping component 6 includes a bending band 61, which is fixedly installed on the outer surface of the protrusion 59 on the side away from the center of the torsion wheel 55. A wave groove 62 is provided on the outer wall of the end of the bending band 61.

[0031] It is worth noting that there are two sets of clamping components 6. Both sets of clamping components 6 are set on the outer surface of the protrusion 59, and the bending band 61 is set in an arc shape. The end of the bending band 61 is inclined towards the center of the arc groove 56, so that when the protrusion 59 comes into contact with the surface of the wire 2 along with the L-shaped block 57, it can better clamp and position the outer sheath of the wire 2. The grooves of the wave grooves 62 opened on the bending bands 61 corresponding to the two sets of clamping components 6 are mirror symmetrically arranged, so that when the wire 2 comes into contact with the end of the bending band 61, the local position can maintain good anti-slip performance, ensuring that the device can stably clamp the wire 2 and prevent it from being damaged or detached when dragged or bent, which would affect the normal and stable use of the wire 2 and the charging head 3.

[0032] In this invention, when in use, the charging head 3 is removed and pulled outwards. At this time, the wire 2 is pulled outwards through the guide wheel 4 and the torsion wheel 55. When the wire 2 needs to be pulled to the side, the wire 2 pulls on the arc groove 56, causing the torsion wheel 55 to drive the slider 52 to deflect at a certain angle on the inner wall of the annular track 51. Through the rotation of the torsion wheel 55, the end of the L-shaped block 57 enters the fan-shaped groove 511 through the through hole opened inside the torsion wheel 55. Under the pressure of the protrusions 59 that are staggered left and right in the arc groove 56, the wire 2 is guaranteed to be positioned on the torsion wheel 55. Even if the wire 2 is twisted in the horizontal direction, its positioning and protection effect can still be guaranteed, avoiding wear on the outer surface of the wire 2, which would affect the safety and service life of the wire 2.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
