Description

Technical Field

[0001] This application relates to the field of charging gun technology, and in particular to an automatic cable retraction mechanism for a charging gun holder. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] For example, Chinese utility model patent CN219056031U discloses a charging gun with an automatic cable retraction function. This charging gun achieves normal charging by pulling the cable out from inside the protective box and charging pile and inserting the charging head into the car charging port. When the charging head is inserted into the charging head holder, the sensor receives a signal to start the motor. The motor then drives the gear to rotate the gear disk counterclockwise, achieving the effect of automatically controlling the cable to rotate and wind inside the gear disk. When the cable passes through the protective box, the rollers installed inside the protective box reduce friction and prevent the cable sheath from being scratched by the protective box. The spring squeezes the sponge sleeve to adhere to the outside of the cable, achieving the effect of cleaning the dust on the outside of the cable.

[0004] Regarding the aforementioned technologies, the inventors believe that the automatic rewinding mechanism of the charging gun holder in the aforementioned technologies requires the use of an auxiliary motor, thereby reducing the practicality of the device.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the issue that the automatic cable rewinding mechanism of the charging gun holder in related technologies requires an auxiliary motor to function, thus reducing the practicality of the device, this application provides an automatic cable rewinding mechanism for the charging gun holder.

[0007] The automatic cable retraction mechanism for a charging gun holder provided in this application adopts the following technical solution:

[0008] An automatic cable retraction mechanism for a charging gun holder includes a charging pile. A cable is installed inside the charging pile, with the end of the cable passing through the side wall of the charging pile and fixedly connected to a charging head. The charging head is inserted into the side wall of the charging pile. The charging pile also has a cable retraction assembly for storing the cable. The cable retraction assembly includes a fixed post fixedly installed inside the charging pile. A fixed disc is rotatably connected to the end of the fixed post. A winding drum is fixedly installed on the side of the fixed disc away from the fixed post. A through hole for the cable to pass through is opened on the side wall of the winding drum. A spring is wound around the outside of the fixed post, with the end of the spring fixedly connected to the fixed disc. A limiting component is provided on the side wall of the charging pile to restrict the rotation of the fixed disc.

[0009] Preferably, the limiting component is slidably disposed on the extrusion column on the side wall of the charging pile, and the end of the extrusion column is fixedly connected to a toothed plate, the end of the toothed plate meshing with a toothed ring, and the toothed ring being fixedly sleeved on the outside of the fixed plate.

[0010] Preferably, a fixed frame is installed on the inner wall of the charging pile, and a sliding plate that is fixedly connected to the extrusion column is slidably arranged inside the fixed frame. A spring is installed between the sliding plate and the side wall of the charging pile, and the spring is sleeved on the outside of the extrusion column.

[0011] Preferably, a limiting plate is fixedly installed at the end of the winding drum away from the fixed plate.

[0012] Preferably, the bottom of the charging pile is fixedly connected to a mounting base, and mounting holes are provided at all four corners of the mounting base.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This application installs a fixed column inside the charging pile, and is equipped with a fixed plate, a winding drum, a spring, and a limiting component. During charging, the cable can be pulled, and the cable drives the spring through the winding drum and fixed plate, and is restricted by the limiting component. After charging is completed, the limiting component is released from the fixed plate. At this time, the spring can drive the fixed plate and the winding drum to rotate, and wind the released cable to achieve automatic cable retraction.

[0015] 2. This application installs a fixed frame on the inner wall of the charging pile, and provides a squeezing column, a sliding plate, a spring, a toothed plate, and a toothed ring. By pulling the squeezing column, the squeezing column drives the sliding column to squeeze the spring, causing the toothed plate to move away from the toothed ring, thereby releasing the restriction on the fixed plate; conversely, by having the toothed plate cooperate with the toothed ring, the fixed plate can be restricted.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses an automatic cable retraction mechanism for a charging gun holder, referring to... Figure 1-5 The device includes a charging pile 1, inside which a cable 2 is installed. The end of the cable 2 passes through the side wall of the charging pile 1 and is fixedly connected to a charging head 3. The charging head 3 is inserted into the side wall of the charging pile 1. The charging pile 1 is equipped with a cable winding assembly for storing the cable 2. The cable winding assembly includes a fixed post 11 fixedly installed inside the charging pile 1. The end of the fixed post 11 is rotatably connected to a fixed plate 12. A winding drum 15 is fixedly installed on the side of the fixed plate 12 away from the fixed post 11. A through hole is opened on the side wall of the winding drum 15 for the cable 2 to pass through. A spring 13 is wound around the outside of the fixed post 11. The end of the spring 13 is fixedly connected to the fixed plate 12. A limiting assembly is provided on the side wall of the charging pile 1 to restrict the rotation of the fixed plate 12.

[0024] Here, the cable 2 can be pulled directly, which can drive the winding drum 15 and the fixed plate 12 to rotate. The fixed plate 12 drives the spring 13 to wind up, and then the fixed plate 12 is limited by the limiting component to perform the charging operation. When the charging is completed, the limiting component releases the restriction on the fixed plate 12. At this time, the spring 13 restores its deformation and drives the fixed plate 12 and the winding drum 15 to rotate, so that the released cable 2 can be wound back, thereby realizing the automatic winding operation.

[0025] Reference Figure 1The limiting component is slidably disposed on the extrusion column 41 on the side wall of the charging pile 1. The end of the extrusion column 41 is fixedly connected to the toothed plate 42. The end of the toothed plate 42 meshes with the toothed ring 14, which is fixedly sleeved on the outside of the fixed plate 12.

[0026] The compression column 41, toothed plate 42 and toothed ring 14 are provided here to restrict the rotation of the fixed plate 12.

[0027] Reference Figure 5 A fixed frame 4 is installed on the inner wall of the charging pile 1. A sliding plate 43, which is fixedly connected to the extrusion column 41, is slidably arranged inside the fixed frame 4. A spring 44 is installed between the sliding plate 43 and the side wall of the charging pile 1. The spring 44 is sleeved on the outside of the extrusion column 41.

[0028] Here, a spring 44 is provided so that the sliding plate 43 can be squeezed, and the sliding plate 43 can push the squeezing column 41 to move.

[0029] Reference Figure 3 A limit plate 16 is fixedly installed at the end of the winding drum 15 away from the fixed plate 12.

[0030] By setting a limit plate 16, the cable 2 can be wound in an orderly manner.

[0031] Reference Figure 1 The bottom of the charging pile 1 is fixedly connected to a mounting base, and mounting holes are provided at the four corners of the mounting base.

[0032] The installation base and mounting holes here allow for stable installation of the charging pile 1.

[0033] The implementation principle of the automatic cable rewinding mechanism of the charging gun holder in this application embodiment is as follows: When in use, the device is placed in a designated position. When charging is required, the squeezing column 41 is pulled first, so that the toothed plate 42 moves away from the toothed ring 14. Then the cable 2 is pulled, which can drive the winding drum 15 and the fixed plate 12 to rotate. The fixed plate 12 drives the spring 13 to wind. When the squeezing column 41 is released, the spring 44 can push the sliding plate 43 and the squeezing column 41 to move, so that the toothed plate 42 can restrict the toothed ring 14 and prevent the fixed plate 12 and the winding drum 15 from rotating, so as to carry out the charging operation. When the charging is completed, the squeezing column 41 is pulled to move the toothed plate 42 away from the toothed ring 14 to release the restriction on the fixed plate 12. At this time, the spring 13 restores its deformation and can drive the fixed plate 12 and the winding drum 15 to rotate, so that the released cable 2 can be wound back, thereby realizing the automatic cable rewinding operation.
