When the vehicle seat is moved to the extreme position, as shown in fig. 10, the harness connecting rod 24 is located on the side of the guide rail 25 close to the box 21, and the harness 23 is placed in the box 21 in a clip shape.
As shown in fig. 11 to 13, the process of paying out the wire harness 23 from the box 21 will be described.
Fig. 11 and 13 show extreme positions of the wire harness paying out process, in which fig. 11 shows the wire harness most remaining in the box 21, and fig. 13 shows the wire harness least remaining in the box 21. In the state shown in fig. 11, the harness connecting rod 24 is slidably disposed on the side of the guide rail 25 close to the winding box 21, the harness connecting rod 24 is driven by the vehicle seat to move in a direction away from the winding box 21, so that the harness 23 is pulled out from the winding box 21, and when the harness 23 is pulled out from the winding box 21, the harness bypasses the second guide 222, passes through the second guide 222, and then protrudes from the opening 211 and enters the guide rail 25. Through the spacing direction of second guide 222 for the pencil 23 is curved in the arc form when rolling out the box 21, can improve the smoothness that pencil 23 was given out. As shown in fig. 12, as the harness connecting rod 24 moves along the guide rail 25, the portion of the harness 23 inside the box 21 becomes smaller, and when the seat moves to the extreme position, as shown in fig. 13, the harness connecting rod 24 is located on the side of the guide rail 25 away from the box 21, and the portion of the harness 23 remaining inside the box 21 becomes the smallest.
As another preferred embodiment of the present invention, as shown in FIG. 4, the roll-up box 21 of the present invention comprises an upper box 212 and a lower box 213, wherein the upper box 212 and the lower box 213 are connected to each other to form the roll-up box 21. Corresponding connecting ear plates are arranged on the peripheries of the upper box body 212 and the lower box body 213, and the upper box body 212 and the lower box body 213 are fastened through screws penetrating through the connecting ear plates. One ends of the upper case 212 and the lower case 213 protrude out of a side portion so that the opening 211 is provided at the protruding portion.
In another preferred embodiment, as shown in FIG. 21, the box 21 includes a plurality of box segments 214 that are joined in a splice so that the box 21 can be adjusted in length as desired. Referring to fig. 22 to 24, the splice plates 2141 are provided on the end surfaces of the box segments 214 that are spliced to another box segment 214, and after the two box segments 214 are spliced, the splice plates 2141 of the two box segments 214 are fitted to each other, so that the two box segments 214 are fastened and connected by fastening bolts. The structure of the segments at two ends of the winding box segments 214 is different from that of the other segments, and the overall size of the winding box 21 is adjusted by selecting the number of the other segments so as to adapt to the adjusting stroke of the automobile seat.
While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
