Door panel opening and closing subassembly includes drive mechanism 1, first swing arm 2, one-way tensile connecting rod 3, one-way compression connecting rod 4, second swing arm 5 and third swing arm 10;Second swing arm 5 and third swing arm 10 have the same structure setting. The middle part of first swing arm 2 is connected with the floor of garbage unloading vehicle room through locating pin shaft (not shown in the drawing), and first swing arm 2 can rotate around locating pin shaft, and the upper end of first swing arm 2 is hinged with the output end of drive mechanism 1 and the upper end of one-way tensile connecting rod 3 through hinge shaft 9, and the lower end of first swing arm 2 is connected with the lower end of one-way compression connecting rod 4 through hinge shaft 9. The lower end of second swing arm 5 is hinged with the lower end of one-way tensile connecting rod 3 through hinge shaft 9, and the upper end of second swing arm 5 is hinged with the pivot 8 of left door panel 6. The lower end of third swing arm 10 is hinged with the upper end of one-way compression connecting rod 4 through hinge shaft 9, and the upper end of third swing arm 10 is hinged with the pivot 8 of right door panel 7. When drive mechanism 1 drives first swing arm 2 to rotate along clockwise, unloading door is closed, one-way tensile connecting rod 3 is first stretched, then drives left door panel 6 to move, one-way compression connecting rod 4 directly drives right door panel 7 to move, and right door panel 7 is closed earlier than left door panel 6. When drive mechanism 1 drives first swing arm 2 to rotate along anticlockwise, unloading door is opened, one-way tensile connecting rod 3 directly drives left door panel 6 to move, one-way compression connecting rod 4 is first compressed, then drives right door panel 7 to move, and left door panel 6 is opened earlier than right door panel 7.

[0026] In the embodiment, by corresponding connection left door panel 6 and right door panel 7 on interval arrangement's a pair of pivot 8, and set swing arm structure, one-way tensile connecting rod 3 and one-way compression connecting rod 4 between a pair of pivot 8, only if drive element 1 drives swing arm structure to rotate, swing arm structure is driven pivot 8 to rotate through one-way tensile connecting rod 3 and one-way compression connecting rod 4, realize two door panels to exist time difference when opening and closing, eliminate the adverse effect brought by two door panels to open and close simultaneously, ensure the sealing property of garbage unloading door.

[0027] In the embodiment, one-way tensile connecting rod 3 and one-way compression connecting rod 4 all adopt spring damping structure, and the time difference of left door panel 6 and right door panel 7 opening and closing comes from the recovery time after spring contraction and stretch, realize the opening and closing time difference of split type unloading door two door panels from mechanical structure, and simple structure and reliable operation.

[0028] As Figure 2As shown, the one-way stretching connecting rod 3 includes a first fixed rod 31, a first movable rod 32 and a one-way stretching spring assembly, the first fixed rod 31 and the first movable rod 32 are respectively as the upper end and the lower end of the one-way stretching connecting rod 3. The two ends of the one-way stretching spring assembly are connected with the first fixed rod 31 and the first movable rod 32 respectively, the first fixed rod 31 is hinged with the second swing arm 5, and the first movable rod 32 is hinged with the first swing arm 2 and the driving mechanism 1. When the driving mechanism 1 drives the first swing arm 2 to rotate clockwise, the first movable rod 32 drives the one-way stretching spring assembly to stretch to the limit position, and then the first fixed rod 31 drives the left door panel 6 to close. When the driving mechanism 1 drives the first swing arm 2 to rotate counterclockwise, the first movable rod 32, the one-way stretching spring assembly and the first fixed rod 31 drive the left door panel 6 to open immediately, and the one-way stretching spring assembly does not deform.

[0029] Further, the one-way stretching spring assembly includes a first spring 33, a limiting rod 34 and a first shroud 35. One end of the first spring 33 is fixed in the first shroud 35, the other end of the first spring 33 is connected with the first movable rod 32, the first movable rod 32 is nested in the first shroud 35, and the limiting rod 34 is clamped between adjacent single coil springs, so as to realize that the first movable rod 32 drives only the first spring 33 to stretch in one direction.

[0030] In this embodiment, the limiting rod 34 is installed in the first shroud 35 and inserted into the middle of the first spring 33. In the initial state, the first spring 33 is in contact with the first movable rod 32 but does not generate force. When the first movable rod 32 is subjected to tension, the first spring 33 is stretched, and the elastic force is increased. When the elastic force is greater than the starting force of the left door panel 6, the first fixed rod 31 drives the left door panel 6 to rotate through the second swing arm 5. When the first movable rod 32 is unloaded, the inertial force of the left door panel 6 and the stretching elastic force of the first spring 33 drive the left door panel 6 to continue to rotate to the mechanical limit of the left door panel 6. When the first movable rod 32 is subjected to pressure, the first spring 33 will not be compressed due to the action of the limiting rod 34, and the first movable rod 32 and the first fixed rod 31 directly drive the left door panel 6 to move.

[0031] As shown in the figure, Figure 2 In this embodiment, the end of the first fixed rod 31 and the end of the first movable rod 32 are respectively provided with a first connecting lug 36 which is screwed. By adjusting the installation position of the first connecting lug 36 at the end of the first fixed rod 31 and the end of the first movable rod 32, the connection distance between the first fixed rod 31 and the second swing arm 5 and the connection distance between the first movable rod 32 and the first swing arm 2 can be adjusted, so as to improve the transmission efficiency of the torque and ensure that the left door panel 6 is opened or closed smoothly.

[0032] As shown in the figure, Figure 3As shown, the one-way compression linkage 4 includes a second fixed rod 41, a second movable rod 42, and a one-way compression spring assembly. The second fixed rod 41 and the second movable rod 42 serve as the upper and lower ends of the one-way compression linkage 4, respectively. The two ends of the one-way compression spring assembly are connected to the second fixed rod 41 and the second movable rod 42, respectively. The second fixed rod 41 is hinged to the third swing arm 10, and the second movable rod 42 is hinged to the first swing arm 2. When the drive mechanism 1 drives the first swing arm 2 to rotate counterclockwise, the second movable rod 42 compresses the one-way compression spring assembly to its limit position, and then the second fixed rod 41 drives the right door panel 7 to open. When the drive mechanism 1 drives the first swing arm 2 to rotate clockwise, the one-way compression spring assembly remains unchanged, and the second movable rod 42, the one-way compression spring assembly, and the second fixed rod 41 then drive the right door panel 7 to close.

[0033] Furthermore, the unidirectional compression spring assembly includes a second spring 43, a limiting block 44, and a second protective cover 45. One end of the second spring 43 is fixed inside the second protective cover 45, and the other end of the second spring 43 is connected to the second movable rod 42. The second movable rod 42 is movably nested inside the second protective cover 45, and an annular limiting block 44 is provided on the inner side of the second protective cover 45 to limit the tensile deformation of the second spring 43, so that the second movable rod 42 drives the second spring 43 to perform unidirectional compression only.

[0034] When the second movable rod 42 is subjected to pressure, the second spring 43 contracts, increasing its elastic force. When the elastic force of the second spring 43 exceeds the starting force of the right door panel 7, the second fixed rod 41 drives the right door panel 7 to rotate via the third swing arm 10. When the pressure on the second movable rod 42 is released, the inertial force of the right door panel 7 and the compressive force of the second spring 43 drive the right door panel 7 to continue rotating until it reaches its mechanical limit. When the second movable rod 42 is subjected to tension, the second spring 43 will not be pulled up due to the limit block 44, and the second movable rod 42 and the second fixed rod 41 directly drive the right door panel 7 to move.

[0035] like Figure 3 As shown, the ends of the second fixed rod 41 and the second movable rod 42 are both provided with threaded second connecting ear plates 46. By adjusting the installation position of the second connecting ear plates 46 at the ends of the second fixed rod 41 and the second movable rod 42, the connection distance between the second fixed rod 41 and the third swing arm 10, as well as the connection distance between the second movable rod 42 and the first swing arm 2, can be adjusted to improve the torque transmission efficiency and ensure that the right door panel 7 opens or closes smoothly.

[0036] In this embodiment, the driving mechanism 1 is a linear actuator, which can be installed on the top of the floor of the garbage discharge pit through a positioning pin. Specifically, the driving mechanism 1 can be in the form of an oil cylinder, which has the characteristics of simple structure and stable transmission. In other embodiments, the driving mechanism 1 can also be in the form of a gas cylinder or an electric push rod, as long as it can drive the second swing arm 2 to rotate smoothly, and realize the stable opening or closing of the left door plate 6 and the right door plate 7 driven by the one-way stretching link 3 and the one-way compression link 4.

[0037] In this embodiment, the closing principle of the discharge door is as follows:

[0038] 1) The driving mechanism 1 retreats, driving the first swing arm 2 to rotate clockwise;

[0039] 2) The one-way stretching link 3 and the one-way compression link 4 are connected with the first swing arm 2, and the one-way stretching link 3 and the one-way compression link 4 generate tension due to the clockwise rotation of the first swing arm 2;

[0040] 3) After the one-way stretching link 3 is subjected to tension, the first movable rod 32 drives the first spring 33 to elongate, and the first fixed rod 31 does not displace. When the first spring 33 is elongated to a certain distance, the first fixed rod 31 begins to displace, driving the second swing arm 5 to move counterclockwise, and the left door plate 6 is connected with the second swing arm 5 and moves counterclockwise synchronously;

[0041] 4) After the one-way compression link 4 is subjected to tension, it directly drives the third swing arm 10 to move clockwise, and the right door plate 7 is connected with the third swing arm 10 and moves clockwise synchronously;

[0042] 5) Due to the time lag of the driving of the left door plate 6 relative to the right door plate 7, the right door plate 7 moves first;

[0043] 6) When the right door plate 7 moves to the closed position, the driving mechanism 1 stops retreating and driving, and the first swing arm 2 stops rotating. Since the first spring 33 in the one-way stretching link 3 is in the elongated state, when the driving tension is lost, the first spring 33 returns to the original length and slowly closes the left door plate 6 to the position.

[0044] In this embodiment, the opening principle of the discharge door is as follows:

[0045] 1) The driving mechanism 1 advances, driving the first swing arm 2 to rotate counterclockwise;

[0046] 2) The one-way stretching link 3 and the one-way compression link 4 are connected with the first swing arm 2, and the one-way stretching link 3 and the one-way compression link 4 generate pressure due to the counterclockwise rotation of the first swing arm 2;

[0047] 3) When the one-way compression connecting rod 4 is compressed, the second movable rod 42 first drives the second spring 43 to shorten, and the second fixed rod 41 does not displace, and when the third spring 43 shortens to a certain distance, the second fixed rod 41 starts to displace, drives the third swing arm 10 to move counterclockwise, and the right door plate 7 connected with the third swing arm 10 moves counterclockwise synchronously;

[0048] 4) When the one-way stretching connecting rod 3 is compressed, it directly drives the second swing arm 5 to move clockwise, and the left door plate 6 connected with the second swing arm 5 moves clockwise synchronously;

[0049] 5) Because the driving time of the right door plate 7 lags behind that of the left door plate 6, the left door plate 6 moves first;

[0050] 6) When the left door plate 6 moves to the open position, the driving mechanism 1 stops forward driving, and the first swing arm 2 stops rotating, and because the second spring 43 in the one-way compression connecting rod 4 is in a compressed state, when the driving tension is lost, the second spring 43 returns to the original length and slowly opens the right door plate 7 to the position.

[0051] The preferred embodiments described above are only the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical scheme falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principles of the present application are also considered to be within the protection scope of the present application.
