Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, and specifically to a top opening type van. BACKGROUND

[0002] The van is safer and more beautiful than the ordinary open truck due to its structural characteristics, and can prevent goods from getting wet in the rain. To improve the transportation efficiency of the van and reduce the transportation cost, the length of this type of van is getting longer (up to 10m at present), which makes it inconvenient to load and unload goods.

[0003] To improve the efficiency of loading and unloading goods, the rear end of the van has been increased with a hydraulic coaming to lift the goods to the height of the van floor. Although this solves the problem of lifting and lowering the goods, it still needs to be horizontally transported, with a length of about 10m. When the size of the goods is larger than the carrying surface of the hydraulic tail plate (about 2.5m square) or the weight is greater than the carrying weight of the hydraulic tail plate, it will not be able to use the hydraulic tail plate to lift and lower. Due to the structural characteristics of the van, even if there is a crane or a hoist, it is still not possible to complete the loading and unloading of special goods.

[0004] The Chinese patent document "Top opening type goods transport van" (patent application number: 201910123471.4) discloses a top opening type goods transport van, which is rotatably connected between the top width of the van and the side width of the van. After the top width of the van is completely opened, the top width of the van is rotated to the side width of the van, improving the efficiency of loading and unloading goods. However, the above-mentioned scheme still has the following defects:

[0005] 1. The top width of the van is a double-opening structure, and there is a risk of rain leakage at the connection;

[0006] 2. The structure is relatively complex, and the connecting rod not only plays a rotating role but also supports the van, which has a short service life and cannot guarantee the overall strength of the van.

[0007] 3. When the top width of the van is opened, the top width and the side width of the van need to be extended to both sides, which occupies a large space and is not conducive to narrow space operation. UTILITY MODEL CONTENTS

[0008] In view of the defects in the prior art, the purpose of the utility model is to provide a top opening type van, which can complete the loading and unloading of goods by means of top hoisting, and is more widely applicable to the size and weight of goods, only limited by the loading and unloading crane, which can improve the efficiency compared with manual handling and hydraulic tail plate loading and unloading.

[0009] The utility model discloses a top opening type van compartment, including bottom plate, front plate, back plate and both side plates, still include drive mechanism and two opposite top plate, the outside lateral edge of top plate is hinged with the upper edge of corresponding side plate through hinge mechanism, the inside lateral edge of one top plate forms the first flat plate portion that horizontal extension is formed to the bottom, and the end of first flat plate portion is bent upwards and forms the first vertical plate portion, and first flat plate portion and first vertical plate portion form first recess portion, the inside lateral edge of another top plate forms the second flat plate portion that horizontal extension is formed to the top, and the end of second flat plate portion is bent downwards and forms the second vertical plate portion, and second flat plate portion and second vertical plate portion form second recess portion, the free end of first vertical plate portion is bent outwards and forms the first flanging portion for holding the inner top wall of second recess portion, the free end of second vertical plate portion is bent outwards and forms the second flanging portion for holding the inner bottom wall of first recess portion, drive mechanism is connected with two top plate respectively for driving two top plate overturning motion.

[0010] Further improvement lies in that the inner bottom wall of the first recess portion is in the form of a slope, and the highest point of the slope is located in the middle of the first recess portion, and the lowest point of the slope is located at the two ends of the first recess portion.

[0011] Further improvement lies in that the maximum overturning angle of the top plate is 90°.

[0012] Further improvement lies in that the drive mechanism comprises four oil cylinders, two of which are arranged in the middle of the upper edge of the front plate, and the other two are arranged in the middle of the upper edge of the back plate.

[0013] Further improvement lies in that the cylinder body of the oil cylinder is connected with the corresponding front plate or back plate through a first connecting seat, and the piston rod of the oil cylinder is connected with the corresponding top plate through a second connecting seat.

[0014] Further improvement lies in that the hinge mechanism comprises a first connecting plate connected with the outer side of the top plate and a second connecting plate connected with the outer side of the side plate, the bottom edge of the first connecting plate is extended downwards in the middle to form a first connecting sleeve, the top edge of the second connecting plate is extended upwards at both ends to form a second connecting sleeve, and the first connecting sleeve is located between the two second connecting sleeves, and a pin shaft passes through the first connecting sleeve and the second connecting sleeve to hinge the first connecting plate and the second connecting plate.

[0015] Further improvement lies in that the end of the pin shaft is provided with a split pin.

[0016] Further improvement lies in that a spacer plate is arranged between the second connecting plate and the side plate.

[0017] Further improvement lies in that the back plate comprises a door frame and two oppositely arranged door plates, and the door frame is provided with a hinge seat for connecting the door plates.

[0018] A further improvement is that the door frame is provided with a handle.

[0019] The beneficial effects of the present invention are:

[0020] 1. This utility model allows for top-lift loading and unloading of cargo, accommodating a wider range of cargo sizes and weights, limited only by the limitations of the overhead crane. This improves efficiency compared to manual handling and hydraulic tail lift loading and unloading. The top panel opens to a maximum angle of 90 degrees, allowing for the simultaneous lifting of cargo up to the width of the carriage without occupying additional space, making it suitable for operations in confined spaces.

[0021] 2. In the present invention, a waterproof groove structure is provided at the intersection of the two top plates, which can effectively prevent water and breathe freely.

[0022] 3. In the present invention, the opening and closing of the top plate is driven by the extension and contraction of the hydraulic cylinder, which has a simple structure and does not affect the overall strength of the carriage. BRIEF DESCRIPTION OF THE DRAWINGS
