Here, only the action stroke and principle of the side plate interlocking hinge fastening knife 9a (the side plate has two fastening knives: 9a and 9b) are described, and the action stroke and principle of the door plate interlocking hinge are the same, which will not be described here.

[0104] Referring to FIG. 20, 9, 8, 21, 5, the interlocking hinge spring slider 13a is built in the middle of the clamping sheet 55a of the side plate interlocking hinge spring seat 8 and the bottom support 25a of the side plate interlocking hinge fastening seat 7; the interlocking hinge spring slider 13b is built in the middle of the clamping sheet 55b of the side plate interlocking hinge spring seat 8 and the bottom support 25b of the side plate interlocking hinge fastening seat 7. Among them, the upper inclined surface 56a of the interlocking hinge spring slider 13a is placed under the bottom surface of the clamping sheet 55a of the side plate interlocking hinge spring seat 8, and the lower inclined surface 56b of the interlocking hinge spring slider 13a is placed on the upper surface of the bottom support 25a of the side plate interlocking hinge fastening seat 7; the upper inclined surface 80a of the interlocking hinge spring slider 13b is placed under the bottom surface of the clamping sheet 55b of the side plate interlocking hinge spring seat 8, and the lower inclined surface 80b of the interlocking hinge spring slider 13b is placed on the upper surface of the bottom support 25b of the side plate interlocking hinge fastening seat 7.

[0105] Referring to FIG. 22, 5, 9, the interlocking hinge spring 38 is connected to the spring shaft hole i of the side plate interlocking hinge spring seat 8 through the shaft hole j, and the spring arms 51a, 51b act on the spring arm sliding grooves 22a, 22b of the spring seat sliders 13a, 13b sliding on the two sides of the side plate interlocking hinge spring seat 8 and the bottom supports 25a, 25b of the side plate interlocking hinge fastening seat 7, respectively, and the spring support 52 is pressed on the bottom support 30 of the side plate interlocking hinge spring seat 8.

[0106] Referring to FIG. 18, 12, 16, 20, 21, the side plate interlocking hinge sliding shaft 47 of the interlocking hinge common main connecting rod passes through the sliding grooves 49 of the side plate interlocking hinge mounting seat 10 on both sides and the common main connecting rod shaft holes I on both sides of one end of the interlocking hinge common main connecting rod 3, and the two ends extending out act in the one-segment sliding groove 36a, the two-segment sliding groove 37a of the spring slider 13a and the one-segment sliding groove 36b, the two-segment sliding groove 37b of the spring slider 13b on both sides, respectively.

[0107] Referring to FIG. 1, 2, 20, 21, 9, 8, 38, 39, 40, when the door panel is opened, the side plate interlocking hinge sliding shaft 47 of the interlocking hinge common main connecting rod simultaneously slides in the sliding groove 49 of the side plate interlocking hinge mounting seat 10 and the one-segment sliding groove 36a and the two-segment sliding groove 37a of the interlocking hinge spring slider 13a and the one-segment sliding groove 36b and the two-segment sliding groove 37b of the interlocking hinge spring slider 13b, because the curves of the spring slider one-segment sliding groove and the two-segment sliding groove are different from the curve design of the sliding groove of the side plate interlocking hinge mounting seat, when the interlocking hinge common main connecting rod side plate sliding shaft 47 slides, the dynamic spring slider one-segment sliding groove and two-segment sliding groove curve track follows the interlocking hinge common main connecting rod side plate sliding shaft 47 to keep consistent with the static mounting seat 10 sliding groove curve track, prompting the interlocking hinge spring slider 13a, 13b to move forward and backward. The same is true when the door panel is closed.

[0108] Referring to Figures 18, 1, 2, 20, 21, 22, 6, 38, 39, and 40, when the door panel is opened, the two ends of the sliding shaft 47 of the side plate of the interlocking hinge common main connecting rod slide within the two-section sliding groove 37a of the interlocking hinge spring slider 13a and the two-section sliding groove 37b of the interlocking hinge spring slider 13b. This causes the interlocking hinge spring sliders 13a and 13b to move in the opposite direction to the opening of the door panel. Since the spring arms 51a and 51b on both sides of the interlocking hinge spring 38 act on the interlocking hinge spring slider 13a... The spring arm groove 22a and the spring arm groove 22b of the interlocking hinge spring slider 13b are located on the spring arm groove 22b. At this time, the spring force is opposite to the force in the opening direction of the door panel, causing the door panel to generate a force in the closing direction. When the door panel is opened to a certain angle, that is, when the two ends of the sliding shaft 47 on the side plate of the common main connecting rod of the interlocking hinge slide to the end point of the first groove 36a of the second section groove 37a of the interlocking hinge spring slider 13a, the spring arm groove 22a is opened on the spring arm groove 22b of the interlocking hinge spring slider 13b. When the interlocking hinge spring slider 13a and 13b reach the starting point of the first section of the sliding groove 36b at the end of the second section of the sliding groove 37b, they will move in the same direction as the door panel opening under the action of the sliding shaft 47 of the side plate of the interlocking hinge common main link. Due to the elastic pushing action of the spring arms 51a and 51b on both sides of the interlocking hinge spring 38, this force is the same as the force in the opening direction of the door panel. This causes the interlocking hinge spring sliders 13a and 13b to push the sliding shaft 47 of the side plate of the interlocking hinge common main link, driving the common main link 3 of the interlocking hinge to rotate until the door panel is fully opened. The reverse is also true.
