Description

Technical Field

[0001] This application relates to the technical field of charging pile cable winding devices, and in particular to a cable clamp, a charging pile gun cable management device, and a charging pile. Background Technology

[0002] With the popularization and promotion of new energy vehicles, the number of charging piles is increasing. Protecting the charging cables has become a common challenge for all charging pile manufacturers. A balancer is needed to manage the cables, ensuring they don't droop, aren't severely twisted, and are properly stored. This extends the lifespan of the charging cables and improves the practicality of the charging pile, making the charging process for new energy vehicles more convenient and easier. Taking a spring balancer as an example, a structure is needed to connect the charging cable to the end of the spring balancer to protect the cable.

[0003] Currently, cable clamps are the primary method for protecting the charging cable of spring balancers. These clamps wrap the cable and secure it to the metal rod end of the spring balancer using a hanging ring or similar structure. While this structure provides basic protection, it has some inherent drawbacks. Firstly, the market offers a variety of charging cable specifications (diameters). To cover all cable models, the same number of cable clamps would be required, increasing manufacturing costs. Secondly, most existing cable clamps are made of rigid plastic, which, when used to wrap the cable, exerts significant pressure on the cable at both ends, easily causing damage to the cable sheath. Thirdly, the cable clamps have poor rotational properties, making them prone to twisting or damaging the cable during actual charging.

[0004] Therefore, it is desirable to provide a cable clamp and charging station that can solve the above problems. Utility Model Content

[0005] The technical problem this application aims to solve is that: there are various specifications (diameters) of gun cables on the market. If all models of gun cables need to be covered, the same number of cable clamps are required, which increases manufacturing costs; existing cable clamps are mostly made of plastic, which is relatively hard. After wrapping the cable, the two ends of the cable clamp exert great pressure on the gun cable, which can easily cause damage to the outer sheath of the gun cable; the cable clamp has poor rotation performance and is easy to twist or damage the gun cable during actual charging.

[0006] This application provides a cable clamp for use with a spring balancer, comprising: an adapter fixedly connected axially to the swing arm of the spring balancer; a rotating sleeve sleeved on the outside of the adapter and the swing arm of the spring balancer, configured to rotate circumferentially around the adapter and the swing arm of the spring balancer; and a cable clamp body, the first end of which is provided with a connecting portion, the cable clamp body being connected to the rotating sleeve through the connecting portion, and the cable clamp body rotating through the rotating sleeve.

[0007] In some embodiments of this application, the adapter includes a first part, a second part, a third part, and a fourth part that are integrally connected in sequence. The swing arm is a hollow column, the first part is a cylinder, and the first part is embedded in the swing arm and fixedly connected to the swing arm by fastening screws.

[0008] In some embodiments of this application, the second part is a cylinder with a diameter greater than that of the first part, and the second part abuts against the end of the swing arm.

[0009] In some embodiments of this application, the third part is a cylinder with a diameter smaller than that of the second part, and a first bearing is sleeved on the outer side of the third part, the first bearing being supported by the second part.

[0010] In some embodiments of this application, the fourth part is a cylinder with a diameter smaller than that of the third part, and a second bearing is sleeved on the outer side of the fourth part, the second bearing being supported by the third part.

[0011] In some embodiments of this application, the rotating sleeve includes an integrally connected thick portion and a thin portion. The thick portion is fitted around the outside of the rocker arm, the first part, the second part, and the first bearing. The inner diameter of the thin portion is smaller than the inner diameter of the thick portion. One end of the thin portion connected to the thick portion is supported on the outer ring of the first bearing.

[0012] In some embodiments of this application, the inner wall of the end of the fine portion away from the thick portion has a protrusion, which is supported on the outer ring of the second bearing.

[0013] In some embodiments of this application, the rotating sleeve further includes a limiting pressure plate that is fixedly connected to the fine part along the axial direction by a fixing member. A retaining wall is provided on the end face of the fine part away from the thick part, and a baffle is provided on the side of the limiting pressure plate connected to the fine part. The retaining wall and the baffle cooperate to limit the rotation angle of the rotating sleeve.

[0014] In some embodiments of this application, the detailed sidewall of the rotating sleeve is provided with a first connecting hole, and the connecting part of the cable clamp body is provided with a second connecting hole corresponding to the first connecting hole. The connecting part and the detailed part are fixedly connected by inserting a first connector into the first connecting hole and the second connecting hole.

[0015] In some embodiments of this application, a pad is also provided inside the cable clamp body.

[0016] In some embodiments of this application, the second end of the cable clamp body is further provided with an end support pad.

[0017] This application also provides a charging pile cable management device, comprising: a base for connecting the charging pile body; a spring, one end of which is connected to the base and extends vertically upward; a swing arm connected to the other end of the spring; and a cable clamp as described above, connected to the swing arm.

[0018] One aspect of this application also provides a charging pile, comprising: a charging pile body; spring balancers disposed on both sides of the charging pile body; and cable clamps as described above, connected to the swing arms of the spring balancers.

[0019] The cable clamp described in this application embodiment has a liner inside the cable clamp body. By changing the thickness of the liner, the diameter of the corresponding cable can be changed, making it suitable for cables of various diameters. An end support pad is provided at one end of the cable clamp body to assist in supporting the cable, reduce the pressure on the charging cable at both ends of the cable clamp, and reduce damage to the outer sheath of the charging cable. The cable clamp body achieves a rotation function through a rotating sleeve to avoid twisting or damaging the charging cable during actual charging. Attached Figure Description
