Technical Field

[0001] This utility model relates to the field of lightweight vehicle body technology, and in particular to a novel lightweight vehicle body. Background Technology

[0002] In the modern transportation sector, vehicle lightweighting has become a key development direction for improving energy efficiency and reducing energy consumption. As the core component of a vehicle for carrying and transporting goods, the lightweight design of the carriage is a major focus of industry research. Lightweight carriages are mainly used for cargo transportation and are an important carrier in the logistics transportation process. They can reduce the weight of the entire vehicle, improve transportation efficiency, and reduce transportation costs, which is of great significance to the development of the logistics industry.

[0003] Traditional carriages often use heavy steel welded to form a frame, which is then covered with solid panels. While this ensures structural strength, the overall weight is large, increasing the vehicle's energy consumption. Furthermore, the connection between the frame and the panels relies heavily on welding or cumbersome bolt fixing, which is not only time-consuming and labor-intensive, but also makes later maintenance and disassembly difficult, making it hard to meet the needs of rapid replacement and repair. Based on this, a new type of lightweight carriage is proposed for improvement. Utility Model Content

[0004] In view of the fact that although the traditional carriage can ensure structural strength, its overall weight is large, which increases the vehicle's energy consumption, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel lightweight carriage, comprising a plurality of long rods, each of which is fixedly connected to a first connector at both ends, and each of which is provided with a connector at both ends. The sidewalls of the connectors are respectively provided with a first groove, a second groove, and a third groove. The first connector is fitted into the inner wall of the first groove, and the first connector and the first groove are threadedly connected by the same first bolt. A short rod is provided on the side of the connector with the second groove, and both ends of the short rod are fixedly connected to a second connector. The second connector is fitted into the inner wall of the second groove, and the second connector and the second groove are threadedly connected by the same second bolt. A vertical rod is provided on the side of the connector with the third groove, and both ends of the vertical rod are fixedly connected to a third connector. The third connector is fitted into the inner wall of the third groove, and the third connector and the third groove are threadedly connected by the same third bolt. All the long rods, short rods, and vertical rods are made of hollow profiles.

[0006] As a preferred embodiment, the long rod has a plurality of first dovetail grooves on its outer side, a first carriage panel is provided on the outer side of the long rod, a plurality of first dovetail plates are fixedly connected to the inner side of the first carriage panel, and the plurality of first dovetail plates are slidably connected to the inner wall of the plurality of first dovetail grooves.

[0007] As a preferred embodiment, the short rod has a plurality of second dovetail grooves on its outer side, a second carriage panel is provided on the outer side of the short rod, a plurality of second dovetail plates are fixedly connected to the inner side of the second carriage panel, and the plurality of second dovetail plates are slidably connected to the inner wall of the plurality of second dovetail grooves.

[0008] As a preferred embodiment, a carriage roof is provided above the long rod, the bottom end of the carriage roof is in contact with the top end of the first carriage panel and the second carriage panel, and a fourth bolt is provided at each of the four corners of the carriage roof, the bottom end of the fourth bolt being threaded to one side of the connector.

[0009] As a preferred embodiment, the roof panel of the carriage has a cavity inside, and the inner wall of the cavity is fixedly connected with a number of composite reinforcing ribs.

[0010] As a preferred embodiment, a ventilation slot is provided at the center of the roof panel of the carriage, and a baffle is provided on the inner wall of the ventilation slot.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects:

[0012] 1. In the use of this utility model, the long rod, short rod, and upright rod are respectively fitted with the connecting parts to form a three-dimensional frame. The first bolt, second bolt, and third bolt ensure the connection strength, so that the force can be evenly transmitted, achieving structural stability under the lightweight design. The first dovetail groove cooperates with the first dovetail plate, and the second dovetail groove cooperates with the second dovetail plate, which can quickly install and connect the first and second carriage panels to the frame, greatly shortening the assembly time. While reducing the overall weight, it enhances the overall rigidity of the sides and top, achieving the goal of "exchanging lightness for high efficiency and maintaining strength with structure", which is conducive to reducing vehicle energy consumption.

[0013] 2. This utility model can reduce the use of materials and reduce the overall weight by opening a cavity inside the roof panel of the carriage.

[0021] To make the above-mentioned objectives, 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.

[0022] Reference Figures 1-5 This is the first embodiment of the present invention, providing a novel lightweight vehicle body, comprising a plurality of long rods 1, each end of which is fixedly connected to a first connector 11. Each end of the long rods 1 is provided with a connector 2. The sidewalls of the connector 2 are respectively provided with a first groove 21, a second groove 22, and a third groove 23. The first connector 11 is fitted into the inner wall of the first groove 21, and the first connector 11 and the first groove 21 are threadedly connected by the same first bolt 24. A short rod 3 is provided on the side of the connector 2 where the second groove 22 is located. Both ends of the short rod 3 are fixedly connected to a second connector 31. The second connector 31 is fitted into the inner wall of the second groove 22. The second connector 31 and the second groove 22 are threadedly connected by the same second bolt 25. The connector 2 has a vertical rod 4 on one side with a third groove 23. Both ends of the vertical rod 4 are fixedly connected to a third connector 41. The third connector 41 is fitted into the inner wall of the third groove 23. The third connector 41 and the third groove 23 are threadedly connected by the same third bolt 26. The long rod 1, the short rod 3 and the vertical rod 4 are all made of hollow profiles.

[0023] During installation, the first connectors 11 at both ends of the long rod 1 are embedded into the first grooves 21 of the connector 2, and the first connectors 11 and the first grooves 21 are tightly fixed by screwing in the first bolts 24, forming the basic long side structure of the car frame. Then, the second connectors 31 at both ends of the short rod 3 are embedded into the second grooves 22 of the connector 2, and the second bolts 25 are screwed in to fix the short rod 3 to the connector 2. At this time, the short rod 3 and the long rod 1 form a 90-degree transverse support structure through the connector 2. Then, the third connectors 41 at both ends of the upright rod 4 are embedded into the third grooves 23 of the connector 2, and fixed by the third bolts 26. The upright rod 4 is perpendicular to the plane where the long rod 1 and the short rod 3 are located, forming a longitudinal support structure. By combining the transverse support structure and the longitudinal support structure, the car frame structure is formed.

[0024] In use, the long pole 1, short pole 3 and upright pole 4 are respectively fitted together with the connector 2 to form a three-dimensional frame. The first bolt 24, the second bolt 25 and the third bolt 26 ensure the connection strength, so that the force can be evenly transmitted when the entire carriage is subjected to loads such as cargo weight and external impact, and achieve structural stability under lightweight design.

[0025] Reference Figures 1-5 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a number of first dovetail grooves 12 are opened on the outer side of the long rod 1, a first carriage plate 5 is provided on the outer side of the long rod 1, a number of first dovetail plates 51 are fixedly connected to the inner side of the first carriage plate 5, and the number of first dovetail plates 51 are slidably connected to the inner wall of the number of first dovetail grooves 12.

[0026] The short rod 3 has several second dovetail grooves 32 on its outer side, and a second carriage plate 6 is provided on the outer side of the short rod 3. Several second dovetail plates 61 are fixedly connected to the inner side of the second carriage plate 6, and the several second dovetail plates 61 are slidably connected to the inner wall of the several second dovetail grooves 32.

[0027] A carriage roof plate 8 is provided above the long pole 1. The bottom end of the carriage roof plate 8 contacts the top end of the first carriage plate 5 and the second carriage plate 6. A fourth bolt 7 is provided at each of the four corners of the carriage roof plate 8. The bottom end of the fourth bolt 7 is threaded to one side of the connector 2.

[0028] During use, after the car frame is installed, several first dovetail plates 51 on the inner side of the first car body panel 5 are aligned with the first dovetail groove 12 on the outer side of the long rod 1. The first dovetail plates 51 are inserted into the first dovetail groove 12 by sliding, so as to achieve a tight fit and fixation between the two. At the same time, it is convenient to install and disassemble quickly. The first car body panel 5, as the side enclosure structure of the car body, works together with the long rod 1 to prevent the goods from shifting to the side and enhance the overall rigidity of the side.

[0029] Next, the second dovetail plate 61 on the inner side of the second carriage panel 6 is slid into the second dovetail groove 32 on the outer side of the short rod 3, so that the second carriage panel 6 and the short rod 3 are firmly connected. The second carriage panel 6, as the end enclosure structure of the carriage, works with the short rod 3 to further improve the sealing of the carriage, while sharing the side force, and together with the first carriage panel 5, forms the side protection system of the carriage.

[0030] Then, the top plate 8 of the carriage is placed on top of the first carriage plate 5 and the second carriage plate 6, so that its bottom end is in close contact with the top end of the first carriage plate 5 and the second carriage plate 6, forming a closed structure of the carriage top. Finally, the fourth bolt 7 is screwed into the four corners of the carriage top plate 8, and the bottom end of the fourth bolt 7 is threaded to the connector 2, so that the weight of the top plate and the load it bears are transferred to the connector 2, and then distributed by the connector 2 to the frame composed of the long rod 1, the short rod 3 and the upright rod 4. The carriage top plate 8 not only plays a role in shielding and protecting, but also enhances the integrity and torsional performance of the entire carriage structure through rigid connection with the frame, so that the components form an organic whole and jointly bear the pressure from the top and the cargo inside, while preventing the first carriage plate 5 and the second carriage plate 6 from shaking or displacing.

[0031] This design, through the cooperation of the first dovetail groove 12 with the first dovetail plate 51 and the second dovetail groove 32 with the second dovetail plate 61, can quickly position and install the first carriage plate 5 and the second carriage plate 6 with the carriage frame, greatly shortening the assembly time. While reducing the overall weight, the tight fit between the plate and the frame enhances the overall rigidity of the sides and top, achieving the design goal of "exchanging lightness for high efficiency and ensuring strength with structure", which is conducive to reducing vehicle energy consumption.

[0032] Reference Figures 1-5 This is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that: a cavity 81 is opened inside the roof panel 8 of the carriage, and a number of composite reinforcing ribs 82 are fixedly connected to the inner wall of the cavity 81.

[0033] A ventilation slot 83 is provided at the center of the roof panel 8 of the carriage, and a baffle 84 is provided on the inner wall of the ventilation slot 83.

[0034] During use, the cavity 81 inside the roof panel 8 can reduce the use of materials and reduce the overall weight. Several composite reinforcing ribs 82 enhance the bending and deformation resistance of the roof panel 8 on the basis of lightweighting, avoid damage caused by local stress concentration, and achieve the effect of "reducing weight without reducing strength". The ventilation slot 83 provides an air circulation channel for the interior of the carriage, and the baffle 84 can control the amount of ventilation by adjusting the angle or opening and closing state.
