Description

Technical Field

[0001] This application relates to the field of carriage technology, specifically a lightweight carriage. Background Technology

[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] Existing small vehicles have simple body structures, generally consisting of an outer shell, a support frame, and internal support panels. This three-layer support structure first protects the entire structure with the outer shell, and then supports the outer shell with the support frame and internal support panels, ensuring the body structure is sturdy. However, this structure is relatively heavy. Since small vehicles have a limited carrying capacity, the body accounts for half of the small vehicle's transport capacity, ultimately affecting the transport efficiency of small vehicles. Therefore, there is a need for a suitable body structure for small vehicles that can reduce the weight of the body while maintaining sturdiness, thereby improving the transport efficiency of small vehicles. Utility Model Content

[0004] To address the aforementioned problems, this application proposes a lightweight carriage.

[0005] The purpose of this application is to provide a lightweight carriage by changing the original structure of the carriage from a multi-layer carriage structure to a single-layer carriage structure. The support plate has honeycomb-shaped hollow partitions, the support rods are made of hollow L-shaped aluminum alloy profiles, and the longitudinal beams are designed in a splicing form. In this way, the weight of the carriage can be reduced while ensuring the original support strength of the carriage, making the carriage suitable for use in small vehicles.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A lightweight vehicle body includes: a bottom frame, a top frame, support rods, and a support plate. The bottom frame and top frame are rectangular and are fixedly connected by support rods. The support rods are perpendicular to the four corners of the bottom frame. The cross-section of the support rod is a hollow L-shaped aluminum alloy profile. A support plate is snapped between two adjacent support rods. One end of the support plate is snapped at the corner of the L-shaped aluminum alloy profile, and the support plate and the L-shaped aluminum alloy profile are fixedly connected by rivets. The support plate is a rectangular honeycomb panel that encloses the sides of the vehicle body. The rectangular honeycomb panel has a honeycomb-shaped hollow partition in the middle.

[0008] As a further preferred embodiment, the top frame is also provided with a top crossbeam, a top plate, and an upper sealing door. The top crossbeam divides the top frame into two parts, one part of which is closed by the top plate and the other part is closed by the upper sealing door. The upper sealing door is hinged to the top crossbeam by a hinge. Hydraulic cylinders are also provided at both ends of the upper sealing door. The rod of the hydraulic cylinder is hinged to the two sides of the upper sealing door near the support plate by a pin, and the cylinder body of the hydraulic cylinder is hinged to the top frame by a pin.

[0009] As a further preferred embodiment, the bottom frame is also provided with a bottom plate, which closes the bottom frame and ensures the flatness of the bottom of the carriage.

[0010] As a further preferred embodiment, the bottom frame is provided with multiple bottom crossbeams and two longitudinal beams. The two ends of the bottom crossbeams are fixedly connected to the two long sides of the bottom frame, respectively. The longitudinal beams are made by splicing a main body and an inner lining. The main body and the inner lining are made of n-shaped profiles. The length of the longitudinal beam is equal to the length of the long side of the bottom frame. The height of the inner lining is less than the height of the main body. The inner lining and the main body are respectively provided with mounting grooves. The width of the mounting grooves is equal to the width of the bottom crossbeams. By corresponding the mounting grooves on the inner lining and the main body, the inner lining and the main body are snapped together into a whole. Then, the longitudinal beams are snapped onto the bottom crossbeams through the mounting grooves, and the two ends of the longitudinal beams are fixed to the short sides of the bottom frame.

[0011] As a further preferred embodiment, the longitudinal beam is also provided with a frame fixing foot, which is used to position and install the entire carriage to the chassis.

[0012] As a further preferred embodiment, a tailgate is also included, which is hinged to the support frame to close the rear of the vehicle compartment.

[0013] As a further preferred embodiment, the support rod, top frame, and bottom frame are all made of hollow L-shaped aluminum alloy profiles, which ensures the supporting effect while minimizing the weight of the carriage.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] 1. This application reduces the weight of the carriage in several ways while ensuring the supporting effect of the carriage. First, the original structure of the carriage is changed from a multi-layer carriage structure to a single-layer carriage structure. Second, the honeycomb hollow partitions in the support plate improve the supporting effect of the plate and reduce the weight of the plate. The support rod adopts hollow L-shaped aluminum alloy profiles to reduce the weight of the carriage while ensuring the supporting strength. Finally, the longitudinal beams are designed in a splicing form, which facilitates installation and reduces the overall weight of the longitudinal beams. Attached Figure Description

[0021] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] A lightweight carriage, such as Figure 1-4 As shown, the structure includes: a bottom frame 2, a top frame 1, support rods 3, and a support plate 4. The bottom frame 2 and the top frame 1 are rectangular and are fixedly connected by support rods 3. The four corners of the support rods 3 are perpendicular to each other, and the top frame 1 is parallel to each other. Thus, the bottom frame 2, support rods 3, and bottom frame 2 form a cuboid frame of the carriage. The cross-section of the support rods 3 is a hollow L-shaped aluminum alloy profile. The support plate 4 is snapped between two adjacent support rods 3. One end of the support plate 4 is snapped at the corner of the L-shaped aluminum alloy profile, and the support plate 4 and the L-shaped aluminum alloy profile are fixedly connected by rivets. The support plate 4 is a rectangular honeycomb panel, which closes the side of the carriage. The rectangular honeycomb panel has a honeycomb-shaped hollow partition in the middle, which reduces the weight of the support plate 4 while ensuring its supporting strength.

[0024] like Figure 1 As shown, the top frame 1 is also equipped with a top crossbeam 7, a top plate 5, and an upper sealing door 6. The top crossbeam 7 divides the top frame 1 into two parts, one part of which is closed by the top plate 5, and the other part is closed by the upper sealing door 6. The upper sealing door 6 is hinged to the top crossbeam 7 by a hinge. The upper sealing door 6 is also equipped with hydraulic cylinders at both ends. The rod of the hydraulic cylinder is hinged to the two sides of the upper sealing door 6 near the support plate 4 by a pin. The cylinder body of the hydraulic cylinder is hinged to the top frame 1 by a pin. In this way, the upper sealing door 6 on the top of the carriage can be opened or closed by extending and shortening the push rod of the hydraulic cylinder, which facilitates the handling of goods.

[0025] The bottom frame 2 is also provided with a bottom plate, which closes the bottom frame 2 to ensure the flatness of the bottom of the carriage.

[0026] like Figure 1 As shown, the bottom frame 2 is provided with multiple bottom crossbeams 9 and two longitudinal beams 8. The two ends of the bottom crossbeams 9 are fixedly connected to the two long sides of the bottom frame 2, respectively. Figure 3-4 As shown, the longitudinal beam 8 is made by splicing the main body 10 and the inner lining 11, which facilitates installation and reduces weight. The main body 10 and the inner lining 11 are made of n-shaped profiles. The length of the longitudinal beam 8 is equal to the length of the long side of the bottom frame 2, and the height of the inner lining 11 is less than the height of the main body 10. The inner lining 11 and the main body 10 are respectively provided with mounting grooves 12. The width of the mounting grooves 12 is equal to the width of the bottom crossbeam 9. By corresponding the mounting grooves 12 on the inner lining 11 and the main body 10, the inner lining 11 and the main body 10 are snapped together into a whole. Then, the longitudinal beam 8 is snapped onto the bottom crossbeam 9 through the mounting grooves 12, and then the two ends of the longitudinal beam 8 are fixed to the short side of the bottom frame 2. In this way, the weight of the longitudinal beam 8 is reduced while ensuring the supporting strength of the longitudinal beam 8.

[0027] The longitudinal beam 8 is also equipped with a frame fixing foot, which is used to position and install the entire carriage to the chassis.

[0028] It also includes a tailgate, which is hinged to the support frame and closes the rear of the vehicle compartment.

[0029] like Figure 2 As shown, the support rod 3, top frame 1 and bottom frame 2 are all made of hollow L-shaped aluminum alloy profiles, which can reduce the weight of the carriage to the greatest extent while ensuring the support effect.

[0030] In the technical solution of this application, the original structure of the carriage is changed from a multi-layer carriage structure to a single-layer carriage structure. The honeycomb hollow partition in the support plate 4 improves the support effect of the plate and reduces its weight. At the same time, the support rod 3 adopts a hollow L-shaped aluminum alloy profile, which reduces the weight of the carriage while ensuring the support strength. Finally, the longitudinal beam 8 is designed in a splicing form, which facilitates installation and reduces the overall weight of the longitudinal beam 8. In this way, the weight of the carriage is reduced in three aspects, so that the carriage achieves the purpose of lightweighting and is suitable for use in small vehicles.

[0031] While the specific embodiments of this application have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this application. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this application are still within the scope of protection of this application.
