[0002] The wingspan vehicle, also known as the wing-opening van, is an improvement of the ordinary van. It is a special vehicle that can open the wing plates on both sides of the carriage through a power spring, a manual device or a hydraulic device. In this way, when the side wings are closed, the whole is an enclosed cargo box, and when the side wings are opened, it has the function of an open cargo box, greatly improving the convenience and efficiency of loading and unloading goods.
[0003] At present, the side wings of the wing-opening carriage are pushed by an oil cylinder. The common positions where the oil cylinder is arranged are above the front and rear enclosures, horizontally arranged, and fixed on the inner sides of the two columns of the front and rear enclosures, longitudinally arranged. Because the piston rod is unevenly stressed on the upper and lower sides when the piston rod pushes the flying wing, the sealing ring on the lower side of the piston rod is severely worn, often resulting in oil leakage of the oil cylinder. Therefore, the longitudinal arrangement of the oil cylinder is preferred. The traditional longitudinal arrangement of the oil cylinder on the inner side of the front and rear enclosure columns occupies the loading height of the rear door, to a certain extent affecting the convenience of loading goods. Therefore, a single-beam wing-opening carriage body structure for trucks is proposed to solve the above problems. Content of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0029] As shown Figures 1-5 in the figure, a single-beam wing-opening carriage body structure for a freight truck proposed by the present utility model includes a bottom plate 1 and two support frames 2 fixedly connected to the bottom plate 1. A group of rear door panels 3 are hinged to the front support frame 2 through hinges. A cross beam 4 is fixedly connected to the support frame 2 shown. A group of wing plates 5 are hinged to the cross beam 4 through hinges. Two groups of oil cylinders 6 are hinged between the two support frames 2 and the wing plates 5.
[0030] It should be noted that a side plate 8 is fixedly connected to the inner side of the rear support frame 2, which is used to seal and block the side close to the vehicle head after the entire carriage is fixed on the vehicle body.
[0031] Among them, a groove 9 for the rotational placement of the oil cylinder 6 is opened at the upper end of the support frame 2. The two groups of oil cylinders 6 are symmetrically distributed between the side of the wing plate 5 close to the support frame 2 and the inner side of the groove 9, so that the oil cylinder 6 located between the groove 9 and the support frame 2 has space for extension and contraction during operation.
[0032] In the present utility model, a fuel supply device for driving the oil cylinder 6 is arranged below the vehicle frame, that is, at the bottom of the vehicle frame, to supply fuel to drive the oil cylinder 6. The fuel supply device is composed of a conventional oil pump, pipeline and driving switch, all of which are existing conventional devices, so they will not be elaborated in the text and figures.
[0033] In an optional embodiment, a placement member 7 for placing goods is arranged on the bottom plate 1; the placement member 7 includes a support frame 71 fixedly connected to the bottom plate 1. A placement plate 72 is slidably connected to the inner side of the support frame 71. A long strip 74 is fixedly connected to the outer side of the placement plate 72. A protective plate 77 is fixedly connected to the bottom plate 1. A limiting member 76 is arranged on the support frame 71.
[0034] It should be noted that the number of support frames 71 is three, and the three support frames 71 are equidistantly distributed on the bottom plate 1. The number of placement plates 72 is two, and the two are symmetrically distributed inside the three support frames 71. The three support the two placement plates 72.
[0035] The protective plate 77 is one of a wooden board or a steel plate, which is used to protect the bottom plate 1 when placing goods. During the assembly process, the wooden board is fixed to the bottom plate 1 by screws, while the steel plate is fixed to the bottom plate 1 by welding.
[0036] Wherein, a number of anti-slip rubber particles 73 are fixedly connected to one side of the placement plate 72 away from the protection plate 77. Through the anti-slip rubber particles 73, the friction between the goods and the placement plate 72 after placement is increased, thereby providing stability during the operation of the goods. A support groove 75 for the long strip 74 to pass through is opened inside the support frame 72. Through the cooperation of the long strip 74 and the support groove 75, the placement plate 72 sliding through the support frame 71 is slidably supported.
[0037] In addition, the number of the support grooves 75 is several, and several support grooves 75 are equidistantly distributed on the support frame 71. The number of the long strips 74 is four, and the four long strips 74 are symmetrically distributed in two groups on both sides of the two placement plates 72. The left and right sides of the placement plate 72 are stably supported by each group of long strips 74.
[0038] In an alternative embodiment, two sets of limit members 76 for limiting the placement plate 72 are provided on each support frame 71. The limit member 76 includes:
[0039] A support block 761 fixedly connected to the lower end of the placement plate 72. A sleeve 762 is fixedly connected to one side of the support block 761. A limit rod 764 whose one end penetrates and extends to the inside of the front support frame 71 is slidably connected to the inside of the sleeve 762. A stopper 763 is fixedly connected to the outer side of the limit rod 764. A spring 765 is fixedly connected between the stopper 763 and the inner side of the sleeve 762.
[0040] It should be noted that a number of limit grooves are opened inside the front support frame 71. The specifications of the limit grooves are adapted to the specifications of the limit rods 764. A number of limit grooves are located below a number of support grooves 75. The placement plate 72 is limited by the limit rods 764 sliding into the limit grooves to prevent the placement plate 72 from moving in the direction perpendicular to the support frame 71.
[0041] In this embodiment, after the placement plate 72 is pushed into the three support frames 71 through the long strips 74 and abuts against the side plate 8, the limit rod 764 is pulled to extend into the limit groove, so as to further limit the movement space of the placement plate 72 and support and fix the placement plate 72.
[0042] The working principle of the above embodiment is:
[0043] Since the support frame 2 is provided with a groove 9 for the telescopic movement of the oil cylinder 6, the height of the oil cylinder 6 is higher when lifting the wing plate 5, and there is also room for movement when pulling the wing plate 5 to extend, making the entire carriage more spacious when opened and not affecting the normal loading and unloading of goods on the side of the rear door panel 3. When loading and unloading goods, opening the rear door panel 3 and lifting the wing plate 5 by the oil cylinder 6 can make the entire carriage in an open state. Workers can manually carry the goods or unload the goods onto the placement plate 72 and the bottom plate 1 by forklift. Since the two placement plates 72 on the three support frames 71 can divide the placement space of the entire carriage into upper, middle and lower layers, and the three layers of goods are separately supported by the two placement plates 72 and the bottom plate 1, the possibility of damage to the bottommost goods caused by stacking of goods is reduced, so as to improve the safety during goods loading. Moreover, the placement plate 72 is located on the support frame 71 and can be separated from the support frame 71 by pulling the limit rod 764 in the sleeve 762. After sliding the placement plate 72 off on the support groove 75, the distribution position of the placement plate 72 can be adjusted up and down to adjust according to the specifications of the goods, improving the convenience of use.
[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
