Description

Technical Field

[0001] The present application relates to the technical field of charging pile wire-reeling devices, and in particular to a charging pile swing arm device and a charging pile. Background Art

[0002] The gun line assisted recovery system is a user-friendly structural device that assists in pulling out and recovering the gun line due to its heavy weight and long length. Currently, auxiliary devices such as coil spring balancers and swing arms are commonly used on the market. This adjustment method has several disadvantages: 1) The coil spring balancer has obvious disadvantages for heavy and long gun lines due to the growth of the coil spring force and the influence of the coil spring's own material. When the balancer rope is pulled out to the end, the user will be subjected to a large pulling force, which fails to achieve the purpose of improving the user experience. In addition, the pull-out rope length of the coil spring balancer is limited, which is not friendly to the gun line manufacturer; 2) Most swing arms on the market do not have a reset function. After the gun line is pulled out, the gun line cannot be recovered to the starting point, and the gun line is easily dragged on the ground and worn. At the same time, the length of most existing swing arms is less than 1 meter, resulting in a large waste of gun line length.

[0003] Therefore, it is hoped to provide a charging pile swing arm device and a charging pile, in which the gun line and the swing arm can automatically reset after use, thereby preventing the gun line from wearing on the ground and improving the user experience. Utility Model Content

[0040] The following description provides specific application scenarios and requirements of the present application, with the purpose of enabling those skilled in the art to make and use the content of this application. Various local modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this application. Therefore, this application is not limited to the embodiments shown, but is intended to be of the widest scope consistent with the claims.

[0041] The technical solution of this application is described in detail below with reference to the embodiments and drawings.

[0042] Figure 1 It is a schematic diagram of the overall structure of the charging pile swing arm device shown in some embodiments of the present application. Figure 2 It is a partial cross-sectional view of a charging pile swing arm device according to some embodiments of the present application.

[0043] refer to Figure 1 and Figure 2 As shown, some embodiments of the present application provide a charging pile swing arm device, comprising: a base 01; a coil spring 04, which is arranged inside the base 01, and the outer end of the coil spring 04 is connected to the base 01; a main shaft 02, the main shaft 02 comprising a first part located inside the base 01 and a second part extending out of the base 01, the first part of the main shaft 02 being connected to the inner end of the coil spring 04, and the main shaft 02 being configured to drive the coil spring 04 to tighten when rotating in a first direction or to be driven by the restoring force of the coil spring 04 to rotate in a second direction; a swing arm 03, the swing arm 03 being connected to the second part of the main shaft 02, and when the swing arm 03 swings in the first direction, it drives the main shaft 02 to rotate in the first direction, or when the restoring force of the coil spring 04 drives the main shaft 02 to rotate in the second direction, it drives the swing arm 03 to swing in the second direction.

[0044] refer to Figure 2 As shown, the base 01 is a special-shaped component, housing a coil spring mounting compartment. A slot is defined within the inner wall of the compartment, and the outer end of the coil spring 04 is hooked into the slot to restrict rotation. The inner end of the coil spring 04 is hooked to the first portion of the spindle 02. Rotation of the spindle 02 adjusts the preload force of the coil spring 04. Specifically, rotation of the spindle 02 generates a preload torque on the coil spring 04, which in turn generates a corresponding preload force on the free end of the swing arm pulling the gun line.

[0045] In some embodiments of the present application, a bearing seat for accommodating and fixing the first bearing 021 is provided at the bottom of the base 01.

[0046] The operating process of the charging pile swing arm device is as follows: When the charging gun is not in use, because coil spring 04 is set with an initial preload force, specifically, because coil spring 04 is set with an initial preload torque, the swing arm 03, with the gun line suspended from the free end, is constrained by this initial preload torque to an initial position defined by a positioning block or buffer block. When the user uses the charging gun, because the gun line of the charging gun is connected to the swing arm 03 of the charging pile swing arm device, the use of the charging gun causes the swing arm 03 to swing, thereby driving the main shaft 02 to rotate and thus tightening the coil spring 04. After the charging gun is used, the coil spring 04 relaxes under the action of the retracting force, driving the main shaft 02 to rotate, and then driving the swing arm 03 to swing, so that the swing arm 03 automatically resets.

[0047] Most swing arms currently available on the market lack a reset function, preventing the gun line from returning to its starting point after being pulled out, causing it to drag and wear on the ground. The technical solution of this application, however, achieves automatic reset of the swing arm and gun line through the coordination of a coil spring and a spindle, offering greater flexibility in space utilization and gun line layout. Furthermore, the structure allows for preload setting by rotating the spindle before use, pre-adjusting the reset force for gun lines of varying lengths and weights. This allows the gun line to automatically return to its starting point after use, ensuring orderly on-site gun line suspension.

[0048] Continue to refer Figure 2 As shown, in some embodiments of the present application, the first portion and the second portion of the main shaft 02 each include a main body and an end portion, and the diameter of the end portion is smaller than the diameter of the main body.

The technical solution of this application installs two bearings (first bearing 021 and second bearing 029) at both ends of the main shaft 02 to limit the axial and radial displacement of the main shaft 02. This dual-bearing structure can withstand large loads without affecting smooth rotation.

[0063] Figure 6 and Figure 7 This is a schematic diagram of the connection structure of the main arm and auxiliary arm of the charging pile swing arm device shown in some embodiments of the present application.

[0064] refer to Figure 6 and Figure 7 As shown, in some embodiments of the present application, the auxiliary arm 032 is connected to the main arm 031 via a secondary shaft 033. The first and second ends of the secondary shaft 033 are respectively provided with a third bearing 035 and a fourth bearing 016. The third bearing 035 is fixedly mounted in the main arm 031. The fourth bearing 016 is fixed by a protrusion 040 located on the secondary shaft 033 and a bearing baffle 036. The auxiliary arm 032 is connected to the main arm 031 via a torsion spring 034. The auxiliary arm 032 and the main arm 031 also use a bearing transmission. A torsion spring 034 is provided on the auxiliary arm 032 to reset the auxiliary arm 032 to form a fixed angle with the main arm 031. The outer side of the fourth bearing 016 is tightened with a screw on the bearing baffle 036 to completely eliminate the axial clearance.
