[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, but not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0025] This chute-type push-turn mechanism is an automatic door panel turning mechanism. Its unique chute design enables the door panel to open and close in a specified direction and angle. Combined with a push mechanism, the door panel can be turned simultaneously with its extension. Combined with a long-travel drive motor and control components, it can achieve long-distance and wide-angle transmission characteristics.

[0026] The specific structure is as Figure 1 As shown, the device comprises a propulsion mechanism 1, a tilting mechanism 2, and a base plate 3. The propulsion mechanism 1 is located at the rear of the main body and serves as the driving portion of the entire device. The base plate 3 is mounted at the bottom of the propulsion mechanism and is integrated with the external equipment platform. Sliding rails 5 are mounted on either side of the propulsion mechanism 1 and above the base plate 3, one on each side and fixed to the base plate. Front and rear stoppers 6 and 4 are located at the front and rear ends of the left and right sliding rails 5, respectively. The tilting mechanism 2 is located in front of the propulsion mechanism 1, with its bottom connected to the propulsion mechanism 1.

[0027] like Figure 2As shown, the propulsion mechanism 1 includes a base 1.1, a long-stroke electric push cylinder 1.3 and a U-shaped bracket 1.2. The base 1.1 has an L-shaped cross-section and is arranged horizontally at the rear of the base plate. To ensure sufficient support strength during operation, four sets of reinforcing ribs are welded on the inner side of the L-shape of the base. A U-shaped bracket 1.2 is installed in the middle of the base. Two pin holes are provided at the front end of the U-shaped bracket 1.2. The bottom of the long-stroke electric push cylinder 1.3 is connected to the pin holes of the U-shaped bracket 1.2 and can rotate freely. After the electric push cylinder is retracted, the total length is 900mm and the push rod extends 700mm. Due to its long size, a support plate 1.4 is installed at the bottom of the long-stroke electric push cylinder to support the cylinder body. The support plate has a cross-section and is fixed to the base plate. A connecting block 1.5 is installed at the front end of the push rod of the long-stroke electric push cylinder 1.3. When the electric cylinder is energized, the connecting block 1.5 extends together with the push rod.

[0028] like Figures 3-5 As shown, the flipping mechanism 2 includes a push plate 2.1, a support plate 2.5, and curved groove guide plates 2.4 fixedly connected on both sides of the door panel 2.2. The push plate 2.1 has a C-shaped cross-section, and its two sides are installed above the sliding guide rail 5, allowing it to move freely back and forth along the sliding guide rail 5. Two mounting holes are provided in the middle front of the push plate 2.1, which are fixedly connected to the connecting block 1.5 in the propulsion mechanism 1. Fixed blocks 2.6 are installed on both sides of the front end of the push plate 2.1, and a bearing 2.7 is installed in the middle of the fixed block 2.6, allowing it to rotate flexibly. A support plate 2.5 is installed at the bottom of the push plate 2.1, and the front end of the support plate 2.5 has a bent bevel. The door panel 2.2 is hinged to the front end of the bottom plate 3 below the push plate 2.1 and the sliding guide rail 5, allowing it to flip outward. Curved groove guide plates 2.4 are installed on both sides of the door panel 2.2. A long guide sleeve 2.3 is installed in the middle of the curved groove guide plate 2.4, specifically on the vertical rod in the middle of the curved groove guide plate 2.4, and the long guide sleeve 2.3 can also rotate freely.

[0029] The curved groove guide plate 2.4 is located on both sides of the push plate 2.1. It includes a notch that accommodates the fixed block 2.6 when the push plate 2.1 moves forward and backward, and a curved groove that accommodates the bearing 2.7. The curved groove consists of an arcuate groove section and a parallel section. The bearing 2.7 slides into the curved groove of the curved groove guide plate 2.4 when the push plate 2.1 moves backward, and slides out of the curved groove of the curved groove guide plate 2.4 when the push plate 2.1 moves forward.

[0030] A space is formed between the support plate 2.5 and the push plate 2.1 to accommodate the long guide sleeve 2.3. When the push plate 2.1 moves backward, the long guide sleeve 2.3 leaves the space between the support plate 2.5 and the push plate 2.1, and when the push plate 2.1 moves forward, the long guide sleeve 2.3 slides into the space between the support plate 2.5 and the push plate 2.1 along the bent bevel of the support plate 2.1.

[0031] The whole transmission principle:

[0032] The turnover mechanism 2 opens: the large stroke electric push cylinder 1.3 of the pushing mechanism 1 is powered, the top rod extends, the push plate 2.1 moves forward on the sliding guide 5, at this time the bearings 2.7 on both sides of the push plate 2.1 slide in the curved guide plate 2.4, when the bearings 2.7 cut into the large circular arc of the curved groove guide plate, the door plate 2.2 is pushed downward together, when the door plate 2.2 opens to the horizontal state, the pushing mechanism 1 continues to move forward, the bearings 2.7 slide forward out of the curved groove guide plate, the long guide sleeve 2.3 slides into the bent inclined edge of the supporting plate, is located between the supporting plate 2.5 and the push plate 2.1 and moves, when the bearings slide out of the curved groove guide plate, the current state is maintained by the supporting plate 2.5, preventing the door plate from falling due to gravity. When the pushing mechanism reaches the maximum size, the push plate triggers the front limit stop, the mechanism stops moving, as shown in Figure 1 The top rod extends.

[0033] The turnover mechanism 2 closes: the large stroke electric push rod is powered, the top rod starts to shrink, driving the push plate 2.1 to move backward. At this time, the long guide sleeve 2.3 continuously moves outward on the push plate 2.1, before disengaging, the bearings 2.7 on both sides of the push plate 2.1 slide into the curved groove guide plate 2.4, after disengaging, the bearings 2.7 drive the movement of the door plate, when the bearings 2.7 enter the downward circular arc of the curved groove, the push plate 2.1 pulls the door plate to rotate upward, slowly closing it, when the push plate triggers the rear limit stop, it stops, the closing process of the turnover mechanism ends.

[0034] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
