Abstract

Disclosed are devices, systems, and methods for a rope guide, and in particular, a magnetic-attraction rope-guide protective shell and a rope guide assembly. In some embodiments, a magnetic-attraction rope-guide protective shell includes a shell body and a magnetic attraction member; and the shell body has an inner cavity for accommodating a rope guide, and the magnetic attraction member is arranged on the shell body and is configured to fix the shell body separated from the rope guide.

Claims (27)

1 . A magnetic-attraction rope-guide protective shell for a vehicle rope guide, comprising:

a shell body having an inner cavity configured to accommodate a rope guide that is configured to be arranged on a vehicle body; and

a magnetic attraction member arranged on the shell body,

wherein the shell body has a protection position and a separation position, wherein, in the protection position, the shell body is configured to cover the rope guide, and wherein, in the separation position, the shell body is configured to be separated from the rope guide and fixed to the vehicle body through the magnetic attraction member to expose the rope guide for operation,

wherein the rope guide has a guide opening running through the rope guide in a first direction,

wherein the shell body comprises a mounting bracket, the mounting bracket arranged in the inner cavity and configured to pass through the guide opening, and

wherein the magnetic attraction member is arranged at an end of the mounting bracket.

2 . The magnetic-attraction rope-guide protective shell according to claim 1 , wherein an end face of the mounting bracket has a mounting cavity, and at least part of the magnetic attraction member is arranged in the mounting cavity.

3 . The magnetic-attraction rope-guide protective shell according to claim 2 , further comprising a buffer pad arranged on the mounting bracket, wherein at least part of the buffer pad protrudes outwards from the end face of the mounting bracket.

4 . The magnetic-attraction rope-guide protective shell according to claim 3 , wherein the magnetic attraction member is arranged in the mounting cavity, one end of the buffer pad is arranged in the mounting cavity, and the other end of the buffer pad is located outside the mounting cavity.

5 . The magnetic-attraction rope-guide protective shell according to claim 4 , wherein the mounting bracket is cylindrical and extends along the first direction, the mounting cavity has a circular cross section, the buffer pad and the magnetic attraction member are circular sheets, and a chamfered surface is arranged between a circumferential wall surface of the mounting cavity and the end face of the mounting bracket.

6 . The magnetic-attraction rope-guide protective shell according to claim 1 , wherein at least two mounting brackets are provided, and the at least two mounting brackets are spaced apart along a second direction, wherein the second direction is orthogonal to the first direction.

7 . A rope guide assembly for a vehicle, comprising:

a rope guide configured to be arranged on a vehicle body; and

a magnetic-attraction rope-guide protective shell,

a shell body having an inner cavity configured to accommodate the rope guide; and

a magnetic attraction member arranged on the shell body,

wherein the shell body has a protection position and a separation position, wherein, in the protection position, the shell body is configured to cover the rope guide, and wherein, in the separation position, the shell body is configured to be separated from the rope guide and fixed to the vehicle body through the magnetic attraction member to expose the rope guide for operation,

wherein the rope guide has a guide opening running through the rope guide in a first direction,

wherein the shell body comprises a mounting bracket, the mounting bracket arranged in the inner cavity and configured to pass through the guide opening, and

wherein the magnetic attraction member is arranged at an end of the mounting bracket.

8 . A vehicle, comprising:

a vehicle body; and

a winch device comprising a rope guide assembly, the rope guide assembly comprising a rope guide arranged on the vehicle body and a magnetic-attraction rope-guide protective shell, wherein the magnetic-attraction rope-guide protective shell comprising comprises:

a shell body having an inner cavity configured to accommodate the rope guide; and

a magnetic attraction member arranged on the shell body,

wherein the winch device is arranged on the vehicle body, the rope guide is located on a surface of the vehicle body, and the shell body has a protection position and a separation position, wherein in the protection position, the shell body covers the rope guide, and in the separation position, the shell body is separated from the rope guide, and the shell body is fixed to the vehicle body through the magnetic attraction member to expose the rope guide for operation.
