Correspondingly, the fastener element group is always closed at the outer part of the slider (341, 342), thereby ensuring the flatness of the cabin interior, that is, the harness cover 5 is not exposed to the environment between the seats. At the same time, the closed element set can also effectively prevent dust from entering the guide rail 6 and the harness cover 5.

The working principle of the wire harness concealed retractable device of the present invention is described in detail below with reference to FIG. 6.

When the movable seat slides forward, among the rollers (331, 332) in the pressing mechanism 33, the first roller 331 guides the harness cover 5 and the second roller 332 presses the harness cover 5. The wire harness 2 and the wire harness cover 5 are pulled out from the winch box 11 and guided by the first roller 331 and the second roller 332. The wire harness 2 and the wire harness cover 5 are pressed into the guide rail 6 and pass through the groove. The cooperation between 61 and the bump 51 secures the harness cover 5 into the guide rail 6. When the movable seat is moved to the forefront, the wire harness 2 and the wire harness cover 5 are basically all pulled out from the winch box 11, and most of them are stored in the guide rail 6 under the carpet 41 to realize the wire harness 2 and the wire harness cover 5. Hide effect. At the same time, during the movement of the zipper adjusting mechanism, the first slider 341 moves forward to open the fastener element group of the zipper, and the second slider 342 moves forward to close the fastener element group of the zipper, so as to ensure the The element set is always closed.

Further, when the movable seat slides backward, among the rollers (331, 332) in the pressing mechanism 33, the second roller 332 guides the harness cover 5 and the first roller 331 squeezes the harness cover 5 . In the pressing mechanism 33, the pressing force applied by the second roller 332 to the harness cover 5 is released. Under the guidance of the first roller 331 and the spring 13, the harness 2 and the harness cover 5 are removed from the carpet 41. The guide rail 6 is pulled out and is then pulled back into the winch box 11. When the movable seat is moved to the initial state, the harness 2 and the harness cover 5 are substantially all retracted into the winch box 11. At the same time, during the movement of the zipper adjusting mechanism, the second slider 342 moves backward and opens the fastener element group of the zipper, and the first slider 341 moves backward to close the fastener element group of the zipper, and maintains the chain of the zipper at the front and rear portions of the pressing mechanism 33 The tooth set is always closed.

Furthermore, when the movable seat continues to slide backward, of the rollers (331, 332) in the pressing mechanism 33, the second roller 332 guides the harness cover 5 and the first roller 331 squeezes the harness cover 5压 效应。 Pressure effect. The wire harness 2 and the wire harness cover 5 are pulled out from the winch box 11 and guided by the second roller 332 and the squeezing action of the first roller 331. The wire harness 2 and the wire harness cover 5 are pressed into the guide rail 6 and pass through the recess The cooperation between the groove 61 and the bump 51 secures the harness cover 5 into the guide rail 6. When the movable seat is moved to the rear end, the wire harness 2 and the wire harness cover 5 are basically all pulled out from the winch box 11, and most of them are stored in the guide rail 6 under the carpet 41 to realize the harness 2 and the wire harness cover 5. Hide effect. At the same time, during the movement of the zipper adjusting mechanism, the second slider 342 moves backward to open the fastener element group of the zipper, and the first slider 341 moves backward to close the fastener element group of the zipper, keeping the fastener elements of the zipper at the front and rear portions of the pressing mechanism 33 The group is always closed.

Those skilled in the art can understand that when the height of the movable seat changes, under the action of the third return spring 35, the first roller 331 and the second roller 332 can always press the carpet 41, and thus can always be The wire harness cover 5 provides sufficient pressing force, so that the wire harness concealed retractable device of the present invention can store and assemble the wire harness cover 5 when the movable seat slides back and forth or when the height of the movable seat changes. hide.

In a preferred embodiment of the present invention, those skilled in the art can understand that the wire harness 2 and the wire harness cover 5 can be pressed into the guide rail 6 located under the carpet 41 through the wire harness concealed retractable device of the present invention, and pass O The zipper hides the wire harness 2 and the wire harness cover 5 pressed into the guide rail 6, and stores the extra wire harness 2 and the wire harness cover 5 in the winch box 11. As a result, the cabin of the car is evener, and since the harness cover 5 is not exposed to the environment between the seats, the safety of the driver and occupant is improved, and the user's car experience is significantly optimized.
