Description

Technical Field

[0001] This utility model belongs to the field of dump truck technology, specifically relating to a side-tipping cargo box with a side door opening structure and a side-tipping dump truck. Background Technology

[0002] A dump truck is an engineering vehicle that automatically lifts its cargo box using hydraulic or mechanical devices to unload goods without manual assistance. A side-tipping dump truck uses a hydraulic system to tilt the cargo box to the left or right to unload goods. It mainly consists of a chassis, a hydraulic lifting mechanism, and a cargo box. The chassis typically includes an engine, transmission system, running system, steering system, and braking system. The cargo box generally includes a floor, parallel-spaced front and rear doors, and two parallel-spaced side doors.

[0003] In existing technologies, the hydraulic devices for the side doors of dump trucks are mainly concentrated on the side of the cargo box or under the chassis. When the hydraulic devices are installed inside the cargo box, they occupy the effective space of the cargo box and affect the loading capacity. When the hydraulic devices are installed under the chassis, the large extension angle of the hydraulic opening device occupies chassis space, restricts the layout of other components, and has poor adaptability and practicality.

[0020] Please refer to the following: Figures 1 to 5 This invention describes a side-tipping cargo box and a side-tipping dump truck with a side-door opening structure. The side-tipping cargo box and the side-tipping dump truck with a side-door opening structure include a cargo box floor 10, side door panels 20, and a side-tipping mechanism 30. The cargo box floor 10 has a front door panel and a rear door panel. The direction of the interval between the front and rear door panels is defined as a first direction, and the direction perpendicular to and horizontal to the first direction is defined as a second direction. There are two side door panels 20, spaced apart along the second direction. Each side door panel 20 is hinged to the cargo box floor 10, and the hinge axis 40 is arranged along the first direction. The side-tipping mechanism 30 corresponds to one of the side door panels 20. The side-tipping mechanism 30 includes multiple side-tipping structures 31, each side-tipping mechanism 30 is disposed on the bottom end of the cargo box floor 10 and spaced apart along the first direction. Each side-tipping structure 31 has a telescopic part. Each side-tilting structure 31 forms a four-bar linkage that includes a telescopic section and is connected to the corresponding side door panel 20. This linkage is used to rotate the corresponding side door panel 20 by tilting it at a small angle through the telescopic section.

[0021] Compared with the prior art, the side-tipping cargo box and side-tipping dump truck with side door opening structure provided in this embodiment have a side-tipping mechanism 30 located at the bottom of the cargo box floor 10, which does not occupy the internal space of the cargo box, thus maximizing the effective loading space of the cargo box. At the same time, it does not occupy the space under the chassis, and the layout of other components on the chassis is more flexible and can be reasonably arranged according to actual needs, improving the utilization rate of chassis space. The four-bar linkage structure drives the side door panel 20 to move through the small-angle flip of the telescopic part. This method makes the opening and closing process of the side door panel 20 more stable, reduces the impact and vibration caused by large-angle flipping, reduces energy consumption, and also reduces the risk of failure. It has good adaptability and practicality.

[0022] In some embodiments, the aforementioned tilting cargo box with a side door opening structure can be adopted as follows: Figures 1 to 5 The structure shown. See also Figures 1 to 5 The side-tipping cargo box with a side door opening structure also includes a hinge shaft 40. There are two hinge shafts 40, and the two hinge shafts 40 are corresponding to the two side door panels 20. Both sides of the cargo box floor plate 10 are provided with multiple side door hinge seats 11 for each hinge shaft 40 to be rotatably connected. Each side door hinge seat 11 located on one side of the cargo box floor plate 10 is spaced apart along the first direction. Each side door panel 20 is provided with a connecting sleeve 21 sleeved on the corresponding hinge shaft 40.

[0023] The hinge shaft 40, in conjunction with multiple side door hinge seats 11 and connecting sleeves 21, provides stable structural support for the hinge and rotation of the side door panel 20. The side door hinge seats 11 are spaced apart along the first direction on both sides of the cargo box floor 10, and cooperate with the connecting sleeves 21 to ensure the stability of the side door panel 20 at the hinge point, allowing the side door panel 20 to rotate around the hinge shaft 40. This stable hinge structure can withstand various forces acting on the side door panel 20 during opening and closing, improving structural reliability, reducing safety hazards caused by loose hinges, and ensuring the smooth operation of the side door opening and closing.

[0024] In some embodiments, the aforementioned rollover structure 31 may adopt the following... Figures 1 to 5 The structure shown. See also Figures 1 to 5Each side-tipping structure 31 includes a fixed base 311, a telescopic component 312, a hinge rod 313, and a support rod 314. The fixed base 311 is fixed to the bottom end of the cargo box floor 10. One end of the telescopic component 312 is hinged to the fixed base 311, with the hinge axis 40 line arranged along the first direction, and the other end of the telescopic component 312 extends outward. One end of the hinge rod 313 is hinged to the side door panel 20, with the hinge axis 40 line arranged along the first direction, and the other end is hinged to the extended end of the telescopic component 312, with the hinge axis 40 line arranged along the first direction. Two support rods 314 are provided, and the two support rods 314 are spaced apart on both sides of the fixed base 311 along the first direction. One end of each support rod 314 is hinged to the fixed base 311, and the hinge axis 40 is set along the first direction. The other end of each support rod 314 extends outward and is hinged to the hinge rod 313. The hinge position of the extended end of each support rod 314 is close to the end of the hinge rod 313 that is hinged to the telescopic component 312.

[0025] The fixed base 311 provides a solid supporting foundation, ensuring the stability of the entire side-tilting structure 31. The telescopic assembly 312, as a power source, provides the power required for the side door panel 20 to tilt through its telescopic movement. The hinge rod 313 and support rod 314 realize the transmission and conversion of force, transforming the telescopic movement of the telescopic assembly 312 into the pitching and rotating motion of the side door panel 20. In this process, the connection method of the hinge rod 313 and support rod 314, and their cooperation with the telescopic assembly 312, enable the side door panel 20 to open and close smoothly, avoiding jamming and shaking during movement, and improving the working efficiency and stability of the side door opening structure.

[0026] In some embodiments, the hinge rod 313 may be as follows: Figures 1 to 5 The structure shown. See also Figures 1 to 5 The hinge rod 313 is located on the outside of the hinge shaft 40. The hinge rod 313 is provided with an abutment groove, which is used to abut against the corresponding hinge shaft 40 when the side door panel 20 is in the closed state.

[0027] The abutment groove on the hinge rod 313 abuts against the corresponding hinge shaft 40 when the side door panel 20 is in the closed state, enhancing the stability of the structure. The cooperation between the abutment groove and the hinge shaft 40 effectively prevents the side door panel 20 from shaking or shifting due to bumps or other external forces during vehicle operation, ensuring that the side door panel 20 always remains in the closed state, improving the sealing of the cargo compartment, preventing cargo leakage, and also reducing friction and collision between the side door panel 20 and other components, thus extending the service life of the side door panel 20.

[0028] In some embodiments, the support rod 314 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2Each support rod 314 is always located below the hinge shaft 40. Each support rod 314 is provided with a support groove, which is used to abut against the corresponding hinge shaft 40 when the side door panel 20 is in the closed state.

[0029] The support groove on the support rod 314 abuts against the corresponding hinge shaft 40 when the side door panel 20 is in the closed state, providing additional support for the side door panel 20. This distributes the weight of the side door panel 20, reducing the burden on the hinge shaft 40 and making the side door panel 20 more stable and reliable when closed. The abutment between the support groove and the hinge shaft 40 also enhances the overall rigidity of the side door opening structure, improves its resistance to external forces, and ensures the safety and stability of the side door during use.

[0030] In some embodiments, the telescopic component 312 may employ, for example... Figures 1 to 5 The structure shown. See also Figures 1 to 5 The telescopic assembly 312 includes a first hinge seat 3121, a telescopic unit 3122, and a second hinge seat 3123. The first hinge seat 3121 is hinged to the fixed seat 311, and the hinge axis 40 is arranged along a first direction. The fixed end of the telescopic unit 3122 is fixed to the first hinge seat 3121, and the extended end of the telescopic unit 3122 extends outward. The second hinge seat 3123 is disposed on the extended end of the telescopic unit 3122 and is integrally connected to the extended end of the telescopic unit 3122. The second hinge seat 3123 is hinged to the corresponding end of the hinge rod 313, and the hinge axis 40 is arranged along the first direction.

[0031] The first hinge seat 3121 enables the telescopic component 312 to be hinged to the fixed seat 311, allowing the telescopic component 312 to rotate relative to the fixed seat 311 and providing a flexible motion basis for telescopic movement. The telescopic unit 3122, as a power output component, has its fixed end fixedly connected to the first hinge seat 3121, and its extended end protruding outwards to provide telescopic power. The second hinge seat 3123 is located on the extended end of the telescopic unit 3122 and is hinged to the hinge rod 313, connecting the telescopic component 312 to the hinge rod 313. This allows the telescopic power of the telescopic unit 3122 to be effectively transmitted to the hinge rod 313, driving the side door panel 20 to move.

[0032] In some embodiments, the telescopic unit 3122 described above may employ, for example... Figures 1 to 5 The structure shown. See also Figures 1 to 5 The telescopic unit 3122 is a hydraulic cylinder.

[0033] The hydraulic cylinder provides powerful output to meet the large force required for the side door panel 20 to flip, ensuring that the side door panel 20 can open and close quickly and stably. Its fast response speed allows it to rapidly extend and retract based on control signals, improving the efficiency of side door opening and closing. Furthermore, the hydraulic cylinder offers high control precision; by adjusting the flow and pressure of the hydraulic oil, the flipping angle and speed of the side door panel 20 can be precisely controlled to adapt to different working scenarios. Simultaneously, the hydraulic cylinder exhibits good stability and reliability, maintaining excellent performance even in harsh working environments.

[0034] In some embodiments, the side door panel 20 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 The side door panel 20 is provided with hinge grooves for hinge rods 313 to be hinged.

[0035] The hinge slot on the side door panel 20 facilitates the connection and rotation of the hinge rod 313. The hinge slot provides a connection point for the hinge rod 313, allowing it to accurately hinge with the side door panel 20. Furthermore, constrained by the hinge slot, the hinge rod 313 can rotate slightly, driving the side door panel 20 to open and close. This design reduces installation errors between the hinge rod 313 and the side door panel 20, improves the assembly accuracy of the side door opening structure, and also makes the side door more stable during movement.

[0036] Based on the same inventive concept, this utility model embodiment also provides a side-tipping dump truck, which includes a side-tipping cargo box with a side door opening structure.

[0037] Side-tipping dump trucks, including those with side-opening cargo boxes, feature a rational spatial layout that improves the vehicle's loading capacity and the flexibility of chassis component layout, thereby enhancing the vehicle's adaptability.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
