[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Example 1: Reference Figure 1-7 , Fig.10 The illustrated mid-flip dump bottom plate opening and closing structure comprises a bottom frame 1 , a bottom plate 2 is arranged on the top surface of the bottom frame 1 , the bottom frame 1 is arranged on the vehicle body, and the bottom frame 1 is used to enhance the bearing capacity and structural strength of the bottom plate 2 .
[0027] The bottom plate 2 is provided with perforations 21, and there are three groups of perforations 21 in this embodiment. At the position of each group of perforations 21, a hydraulic cylinder 3 adapted thereto is provided on the vehicle body for providing power to flip up the opening and closing mechanism.
[0028] The opening and closing mechanism corresponds to each group of perforations 21, and each group of opening and closing mechanisms is lifted up by an independent hydraulic cylinder 3. The flap 5 and the extension plate 6 of the opening and closing mechanism are overlapped and connected by a slider 51 and a slide groove 61. To prevent the extension plate 6 from falling off, the cross-sections of the slider 51 and the slide groove 61 are both T-shaped. Through the above structure, the center axis of the truck bed is flipped to both sides, which plays a role in balancing and preventing overturning during use. The two groups of flaps 5 are connected by hinges 7.
[0029] The limiting grooves in the guiding mechanism include a straight groove 41 and a transverse groove 42, which are L-shaped. The two sets of vertical plates at the front and rear ends are provided with limiting grooves on their opposite surfaces, and the middle vertical plates are provided with limiting grooves on both end surfaces. Block No. 1 52 is provided at the end of the flap 5, and block No. 2 62 is provided at the end of the extension plate 6. Block No. 1 52 slides in the straight groove 41, and block No. 2 62 slides in the transverse groove 42. Therefore, when lifted by the hydraulic cylinder 3, with the assistance of the limiting grooves, the opening and closing process of the opening and closing mechanism is smooth, avoiding the problem of jamming.
[0030] In this embodiment, three groups of opening and closing mechanisms are designed, and vertical plates 4 are provided between each adjacent group of opening and closing mechanisms.
[0031] Example 2: Reference Figure 8-9 shown.
[0032] In this embodiment, a middle plate is added between the two groups of flaps 5, and the two ends of the middle plate are respectively connected to the two groups of flaps 5 through hinges 7. The bottom surface of the middle plate is slidably connected to the telescopic end of the hydraulic cylinder 3, and block No. 1 52 is arranged at the front and rear ends of the middle plate.
[0033] The utility model works as follows: by starting the hydraulic cylinder 3, the telescopic end of the hydraulic cylinder 3 passes through the through holes 21 of the base frame 1 and the bottom plate 2, and lifts up the flap 5. The two groups of flaps 5 are connected by hinges 7. The flap 5 slides in the straight groove 41 of the vertical plate 4 through block No. 1 52, so that the flap 5 is tilted. At the same time, the transverse groove 42 and the block No. 2 62 on the extension plate 6 cooperate. The flap 5 cooperates with the slide groove 61 on the extension plate 6 through the slider 51. The block No. 1 52 moves upward and the block No. 2 62 moves toward the middle, so that the entire opening and closing mechanism changes from an "I" shape to an "A" shape, thereby achieving the purpose of stabilizing the vehicle body and symmetrical unloading, and reducing the possibility of rollover compared to existing truck buckets.
