Cable fixing device

1. A vehicle cable fixing system, comprising:

a suspension system of a vehicle, wherein the suspension system is configured to undergo an up-and-down or side-to-side movement;

a first bracket fixed to a housing of an in-wheel driving device of the vehicle, and installed in a shape to cover one side of a cable connected to the in-wheel driving vehicle;

a second bracket positioned opposite to the first bracket with respect to the cable, and fixed to the first bracket such that tension or stress from the up-and-down or side-to-side movement of the suspension system is transferred to the cable inserted in between the first bracket and the second bracket; and

a buffer installed on at least one of the first bracket and the second bracket, and made of an elastic material to that reduces the tension or the stress from the up-and-down or side-to-side movement of the suspension system transferred to the cable,

wherein the buffer comprises a coupling groove and a coupling protrusion that is configured to be inserted into the coupling groove.

2. The vehicle cable fixing system of claim 1 , wherein the first bracket comprises:

a first body fixed to outside of the housing, and extended in a linear direction; and

one or more first seating grooves formed at a surface of the first body which faces the cable, such that the cable is seated in one of the first seating grooves.

3. The vehicle cable fixing system of claim 2 , wherein the first seating grooves are installed on the first body.

4. The vehicle cable fixing system of claim 3 , wherein the second bracket comprises a second body which faces the first body and is extended in a linear direction.

5. The vehicle cable fixing system of claim 4 , wherein the buffer comprises:

a first buffer installed over the first seating grooves and the first body; and

a second buffer installed on the second body facing the first buffer.

6. The vehicle cable fixing system of claim 5 , wherein the first buffer comprises:

a first curved body installed over the first seating grooves; and

a first stress distribution groove formed on one side of the first curved body, facing the cable, configured so as to reduce the tension or the stress.

7. The vehicle cable fixing system of claim 6 , wherein the first stress distribution groove is formed in a grid shape.

8. The vehicle cable fixing system of claim 6 , wherein the second buffer comprises:

a second curved body installed at a position facing the first curved body, and configured so as to be in contact with the cable; and

a second stress distribution groove formed on one side of the second curved body, facing the cable, configured so as to reduce the tension or the stress.

9. The vehicle cable fixing system of claim 8 , wherein the second stress distribution groove is formed in a grid shape.

10. The vehicle cable fixing system of claim 5 , wherein the first buffer further comprises the coupling groove formed at a surface facing the second buffer, and

the second buffer further comprises the coupling protrusion protruding toward the coupling groove.

11. The vehicle cable fixing system of claim 2 , wherein:

the one or more first seating grooves comprises two or more first seating grooves;

a base of the buffer on the first bracket configured to be in contact with at least the one or more first seating grooves is shaped to match a shape of the one or more first seating grooves configured to be in contact with the base of the buffer or the first bracket; and

the second bracket comprises a planar base with two walls on each end configured to house the buffer on the second bracket with a planar base which is configured to be in contact with the planar base of the second bracket when the buffer on the second bracket is installed.

12. A cable fixing system, comprising:

a vehicle suspension system configured to undergo an up-and-down or side-to-side movement;

a first bracket, fixed to a housing of an in-wheel driving device of the vehicle, and configured in a shape that covers a first side of a cable;

a second bracket positioned opposite to the first bracket with respect to the cable, and fixed to the first bracket;

a first buffer, installed on the first bracket, and comprising a first stress distribution groove; and

a second buffer, installed on the second bracket, and comprising a second stress distribution groove,

wherein the second stress distribution groove is formed in a grid shape.
