[0002] With the continuous development of science and technology, sliding doors are widely used in various types of vehicles. However, in the existing sliding doors, for example, if the traditional sliding door adopts the outward opening method, the outer opening handle is pulled to drive the sliding door rear lock and the limit lock through the conversion bracket; the inner opening handle is pulled to open the rear lock or the inner closing handle is pulled to open the limit lock through the conversion mechanism. The above-mentioned door opening methods usually have the problems of inconvenient operation, complicated transmission wires, large space occupied by the conversion mechanism, and high maintenance costs.

[0003] The traditional pull-wire conversion mechanism is large, the conversion mechanism is complex, and the travel loss is large, which increases the risk of the door not opening. Moreover, with the continuous development of technology, more and more functional requirements are required, and the internal space of the sliding door is limited, which not only makes it difficult for designers to arrange it, but also increases the inconvenience of assembly for operators. The failure rate and maintenance cost of the actual vehicle in the later stage will also be greatly increased.

[0004] Therefore, a solution needs to be proposed to solve this problem. Summary of the invention

[0018] The present invention is described in detail below in conjunction with the accompanying drawings.

[0019] A sliding door pull wire linkage device, such as Figure 1-Figure 2 As shown, it includes a door body, in which an outward opening handle 1, a front lock 2 and a rear lock 3 are arranged, the outward opening handle 1 is connected with an outward opening rear lock pull wire 4, an outward opening ground lock pull wire 5 and an outward opening front lock pull wire 6, the outward opening rear lock pull wire 4 is connected to the rear lock 3, the outward opening front lock pull wire 6 is connected to the front lock 2, a linkage device is arranged between the outward opening rear lock pull wire 4, the outward opening ground lock pull wire 5 and the outward opening front lock pull wire 6, an inner opening ground lock pull wire 7 is arranged on the inner side of the outward opening handle 1, the inner opening ground lock pull wire 7 is connected with an inner opening rear lock pull wire 8 and an inner opening front lock pull wire 9 through an adapter, the inner opening rear lock pull wire 8 is connected to the rear lock 3, and the inner opening front lock pull wire 9 is connected to the front lock 2.

[0020] The linkage device includes an outer shell 10, which is fixedly installed in the door body. A slider 11, a slider 2 12 and a slider 3 13 are slidably connected in the outer shell 10. The slider 3 13 is fixedly connected to the outward opening rear lock pull wire 4, the slider 2 12 is connected to the outward opening ground lock pull wire 5, the slider 1 11 is connected to the outward opening front lock pull wire 6, and a through hole is opened on the outer shell 10 for the outward opening ground lock pull wire 5, the outward opening rear lock pull wire 4 and the outward opening front lock pull wire 6 to pass through. A connecting piece 1 is arranged between the slider 2 12 and the slider 3 13, and a connecting piece 2 is arranged between the slider 1 11 and the slider 2 12.

[0021] The connecting member 1 includes a vertical rod 14 fixedly connected to the side wall of the sliding block 2 12 , and a slot 1 is provided on the vertical rod 14 , and an inner core iron rope 15 is fixedly connected in the slot 1 , and the inner core iron rope 15 is fixedly connected to the sliding block 3 13 .

[0022] The second connecting member includes a second vertical rod 16 fixedly connected to the side wall of the first slider 11 . The second vertical rod 16 is provided with a second clamping groove 17 . The second clamping groove 17 is fixedly connected with an inner core iron rope 2 . The inner core iron rope 2 is fixedly connected to the second slider 12 .

[0023] Working principle: first, pull the outer opening rear lock wire 4 through the outer opening handle 1, and the rear lock 3 wire will pull and open the rear lock 3. At the same time, the outer opening rear lock wire 4 can drive the slider 3 13 to move. Since the slider 2 12 is connected to the slider 3 13 through the inner core iron cable 1 15 and the vertical rod 1 14, the sliding of the slider 3 13 can drive the slider 2 12 to move together. The slider 2 12 can drive the slider 1 11 to move together through the inner core iron cable 2 and the vertical rod 2 16. The slider 2 12 and the slider 1 11 can simultaneously pull the outer opening ground lock wire 5 and the outer opening front lock wire 6, so that the ground lock and the front lock 2 can also be opened together. In this way, no matter whether it is an outer opening door, Whether the door is closed from the outside or from the inside, the front lock 2, rear lock 3 and ground lock can be easily opened at the same time. The structure is simple, the complex conversion mechanism is reduced, and the production cost and maintenance cost are reduced. At the same time, the arrangement space of the pull-wire linkage is small. By reasonably arranging the pull-wires and the linkage device, the space shortage problem caused by the complex conversion mechanism can be reduced in a limited space. The arrangement is flexible. When opening from the inside, the inside ground lock pull wire 7 is pulled first, and the inside ground lock pull wire 7 is converted into two through the adapter. One way is the inside rear lock pull wire 8 to directly open the rear lock 3, and the other way is the inside front lock pull wire 9 to pull the front lock 2 pull wire through the slider 11 in the outer shell 10 to open the front lock 2.
