Description

Technical Field

[0001] This utility model relates to the technical field of anti-inflation box compartments for vans, and in particular to a lightweight anti-inflation box compartment for vans. Background Technology

[0002] The cargo box of existing vans typically consists of a roof, side panels, and a floor. Common side panels include a left panel, a right panel, a front panel, and a rear door. Currently, there are many types of cargo boxes used, such as in trucks, buses, and trains. However, different industries use different types of cargo boxes, so the application range of cargo boxes is very wide.

[0003] When transport vehicles are fully loaded or carrying irregularly shaped, hard, or bulk goods, especially during transport when sudden braking or turning due to road conditions can cause significant centrifugal force, the cargo compartment is prone to deformation or damage. Therefore, how to maintain the overall lightweight design of the cargo compartment while installing protective devices is one of the challenges faced by vehicle designers. Utility Model Content

[0004] Therefore, it is necessary to provide a lightweight anti-inflation box for a van to address the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a lightweight anti-inflation box for a van, comprising a box body and a door installed on the box body. A pressure cylinder is installed on the box body, and a pressure source is inside the pressure cylinder. A piston plate is slidably and sealed inside the pressure cylinder, and a connecting frame is slidably engaged on the pressure cylinder. The connecting frame is connected to the piston plate. A spring is installed inside the pressure cylinder, and the output end of the spring is connected to the piston plate. Several hollow vertical rods are installed on the box body, and several hollow horizontal tubes are installed on the hollow vertical rods near the inner side of the box body. The hollow horizontal tubes are connected to the pressure cylinder. A pressure telescopic rod is installed on the box body, and the hollow horizontal tubes are connected to the pressure telescopic rod. A friction plate is installed at the output end of the pressure telescopic rod. A spring is installed on the hollow vertical rod, and the output end of the spring is connected to the friction plate.

[0006] Preferably, a telescopic support rod is installed on the hollow vertical rod, and the output end of the telescopic support rod is connected to the friction plate.

[0007] Preferably, a plurality of friction blocks are mounted on the friction plate.

[0008] Preferably, a sponge cushioning pad is installed on the connecting frame, and a fixing plate is installed on the sponge cushioning pad.

[0009] Preferably, each of the friction plates is connected to four springs, which are evenly distributed on the friction plates.

[0010] Preferably, each of the friction plates is connected to four telescopic support rods, which are evenly distributed on the friction plates.

[0011] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0012] By cooperating with the pressure cylinder and the connecting frame, when the vehicle brakes suddenly, the cargo slides forward and squeezes the connecting frame and the piston plate. The piston plate slides into the pressure cylinder. The pressure source inside the pressure cylinder is delivered through the hollow horizontal tube, causing the friction plate to extend, thereby clamping and rubbing the cargo from both sides, reducing the collision of the cargo with the front of the carriage during sudden braking.

[0013] When the vehicle turns, the centrifugal force is large, and the cargo squeezes the friction plate on one side. At this time, the squeezed friction plate transmits the pressure source to the friction plate on the opposite side and the piston plate. Therefore, the cargo offset can be reduced by the pulling balance of spring one and spring two on both sides.

[0014] By setting the pressure source in the pressure cylinder and hollow horizontal tube as a pneumatic source, and cooperating with the hollow vertical rod and hollow horizontal rod, the overall weight of the carriage can still be maintained. Attached Figure Description

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 4 This application provides a lightweight anti-inflation box for a van, including a box body 1 and a door 2 installed on the box body 1. A pressure cylinder 3 is installed on the box body 1, and a pressure source is inside the pressure cylinder 3. A piston plate 4 is slidably and sealed inside the pressure cylinder 3. A connecting frame 5 is slidably engaged on the pressure cylinder 3 and connected to the piston plate 4. A spring 6 is installed inside the pressure cylinder 3, and the output end of the spring 6 is connected to the piston plate 4. Several hollow vertical rods 12 are installed on the box body 1, and several hollow horizontal tubes 7 are installed on the hollow vertical rods 12 near the inside of the box body 1. The hollow horizontal tubes 7 are connected to the pressure cylinder 3. A pressure telescopic rod 8 is installed on the box body 1, and the hollow horizontal tubes 7 are connected to the pressure telescopic rod 8. A friction plate 9 is installed at the output end of the pressure telescopic rod 8. A spring 10 is installed on the hollow vertical rods 12, and the output end of the spring 10 is connected to the friction plate 9.

[0022] In this embodiment, the pressure source in the pressure cylinder 3 can be pneumatic or hydraulic. To make the vehicle lighter, pneumatic pressure can be selected as the pressure source. When the vehicle brakes suddenly during the transportation of goods, the goods slide forward due to inertia, thereby squeezing the connecting frame 5 sliding on the pressure cylinder 3. The connecting frame 5 drives the piston plate 4 to slide into the pressure cylinder 3. The pneumatic pressure in the pressure cylinder 3 and the spring 6 provide a certain squeezing and buffering effect on the piston plate 4. At the same time, when the piston plate 4 squeezes the gas in the pressure cylinder 3, the pneumatic pressure travels along the hollow horizontal tube 7 through the pressure telescopic rod 8 to move the friction plate 9 forward, thus the friction plates installed on both sides of the body... 9 can simultaneously exert force to squeeze and rub the cargo, thereby improving the braking efficiency of the cargo; when the vehicle turns, and the cargo is deflected by a relatively small centrifugal force, the cargo squeezes the friction plate 9 on one side, causing it to drive the pressure telescopic rod 8 to retract inward, thereby squeezing the air pressure to the piston plate 4 and the friction plate 9 on the opposite side. At this time, the spring 10 on the squeezed side is pushed outward by the pressure, and the spring 6 on the piston plate 4 and the spring 10 on the opposite friction plate 9 pull back the two that have been squeezed out by the air pressure, so that the air pressure returns to the friction plate 9 on the squeezed side, thereby protecting the cargo from deflection. When the cargo stops sliding, spring 2 10 drives the pressure telescopic rod 8 to contract through the friction plate 9, thereby squeezing the gas pressure in the hollow horizontal tube 7 back into the pressure cylinder 3, causing the piston plate 4 to automatically reset. The connecting frame 5 is approximately a U-shaped frame, with the top forked end connected to the piston plate 4. The purpose is to prevent uneven force on the piston plate 4 when the cargo directly squeezes it, which could easily cause the piston plate 4 to shift. The purpose of setting the hollow vertical rod 12 and placing the hollow horizontal rod 7 inside the hollow vertical rod 12 is to improve the overall anti-expansion capability of the carriage and avoid direct damage to the carriage or the hollow horizontal rod 7. Both of these, as well as the pressure cylinder, are hollow, thus allowing the carriage to remain lightweight.

[0023] In some embodiments, to protect the pressure telescopic rod 8, a telescopic support rod 11 is installed on the hollow vertical rod 12, and the output end of the telescopic support rod 11 is connected to the friction plate 9. The telescopic support rod 11 installed on the hollow vertical rod 12 reduces the radial force on the pressure telescopic rod 8, thus preventing the friction plate 9 from shifting due to uneven force distribution.

[0024] In some embodiments, to further improve the braking efficiency of the friction plate 9 on the cargo, a plurality of friction blocks 13 are installed on the friction plate 9.

[0025] In some embodiments, to prevent the friction plate 9 from squeezing and damaging the goods when they slip slightly, a sponge cushioning pad 14 is installed on the connecting frame 5, and a fixing plate 15 is installed on the sponge cushioning pad 14. When the goods slip slightly, the fixing plate 15 squeezes the sponge cushioning pad 14, and after the sponge cushioning pad 14 cushions the movement, it can push the fixing plate 15 back to its original position.

[0026] In some embodiments, to ensure uniform force distribution on the friction plates 9, four springs 10 are connected to each friction plate 9, and the springs 10 are evenly distributed on the friction plates 9. Four telescopic support rods 9 are also connected to each friction plate 9, and the telescopic support rods 9 are evenly distributed on the friction plates 9. The distributed telescopic support rods 9 reduce the radial force on the pressure telescopic rods 8 when the friction plates 9 rub, thus preventing damage to the pressure telescopic rods 8. When the goods stop sliding, the distributed springs 10 pull the friction plates 9, causing the pressure telescopic rods 8 to retract, thus ensuring uniform force distribution on the pressure telescopic rods 8.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
