Description

Technical Field

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

[0002] Against the backdrop of increasingly prominent pain points in the manufacturing and maintenance of traditional welded carriages, the widespread application and development of "assembled carriage" technology has been spurred by the maturity of lightweight materials (aluminum, composite panels), breakthroughs in high-strength / high-reliability connection technologies (adhesives, fasteners, specialized clips), the popularization of modular / standardized design concepts and tools (CAD / CAE), and improvements in precision manufacturing processes. This, combined with strong market demand for high efficiency, low cost, easy maintenance, and flexible customization, represents a concrete manifestation of the manufacturing industry's evolution towards modularization, intelligence, and green technology in the field of transportation equipment.

[0003] Existing modular car bodies, when designed, only focus on the assembly itself and lack guidance for each assembly module. In the actual installation process, the entire upper and lower frame are assembled solely by positioning blocks, which makes alignment quite difficult and thus reduces installation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a novel modular carriage to overcome the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel modular car body, comprising a lower frame welding assembly and an upper welding component, wherein a positioning block is fixedly installed on the lower frame welding assembly, and a guide mechanism is provided at each of the four corners of the lower frame welding assembly, the guide mechanism being adapted to the upper welding component.

[0006] As a further description of the above technical solution: the upper welding assembly is composed of front and rear frame frames at both ends, top surface frame frame at the top, and upper frame frame in the middle, all welded together. A connecting seat is fixedly installed at the bottom of the upper frame frame. A connecting frame frame is welded around the lower frame welding assembly. Mounting holes are provided on the connecting frame frame. The positioning block is fixedly installed on both sides of the connecting frame frame. A connecting bolt group and a column fastener are provided between the upper welding assembly and the mounting holes.

[0007] As a further description of the above technical solution: the guiding mechanism includes four slides, which are slidably installed at both ends of the connecting frame. Guide rods are rotatably connected to the four slides, and limit frames are fixedly installed on the guide rods. A locking component is provided between the guide rods and the slides.

[0008] As a further description of the above technical solution: the limiting frame is provided with a connecting hole, and the limiting frame is configured as a J-shaped frame.

[0009] As a further description of the above technical solution: the locking component includes a plug-in bracket, the bottom end of the guide rod is provided with four plug-in slots, the slide block is provided with two through slots, and a threaded knob is rotatably connected to one side of the plug-in bracket, the threaded knob being threadedly connected to the slide block.

[0010] As a further description of the above technical solution: a flap assembly is fixedly installed on the lower frame welding assembly, an upward-opening door assembly is provided on one side of the flap assembly, a curtain door assembly is fixedly installed on the upper welding assembly, guard plate assembly assemblies are fixedly installed on both sides of the top of the upper welding assembly, a top cover is fixedly installed on the top of the upper welding assembly, and an interior panel assembly is provided between the upper welding assembly and the lower frame welding assembly.

[0011] This utility model provides a novel modular carriage. It has the following advantages: When assembling the carriage using this device, it is difficult to directly assemble the upper welding components and the lower frame welding assembly using only the positioning blocks. Therefore, this device is additionally equipped with a guiding mechanism to guide the upper welding components in advance when they are lowered, ensuring that the upper welding components can successfully dock with the positioning blocks.

[0012] Meanwhile, the carriage is broken down into multiple standardized functional modules (such as side panels, roof panels, floor panels, door frames, corner pillars, etc.). Each module undergoes precision machining, pre-assembly (such as pre-embedded cables and pre-installed interior parts) and quality control in the factory. One of the biggest advantages is that damaged parts are easy to replace. Simply remove the damaged module and replace it with a new prefabricated part, making maintenance convenient, low-cost, and quick.

[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0014] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-14 The new type of modular car body includes a lower frame welding assembly 1 and an upper welding component 2. A positioning block 3 is fixedly installed on the lower frame welding assembly 1, and a guide mechanism is provided at each of the four corners of the lower frame welding assembly 1. The guide mechanism is adapted to the upper welding component 2. When the car body is assembled using this device, it is difficult to directly assemble the upper welding component 2 and the lower frame welding assembly 1 by relying solely on the positioning block 3. Therefore, this device is additionally equipped with a guide mechanism to guide the upper welding component 2 in advance when it is lowered, so as to ensure that the upper welding component 2 can successfully dock with the positioning block 3.

[0033] As a preferred technical solution of this embodiment, the upper welding assembly 2 is composed of front and rear frame frames 4 at both ends, top surface frame 5 at the top, and upper frame 6 in the middle, which are welded together. A connecting seat 7 is fixedly installed at the bottom of the upper frame 6. A connecting frame 8 is welded around the lower frame welding assembly 1. The connecting frame 8 is provided with mounting holes 9. The positioning block 3 is fixedly installed on both sides of the connecting frame 8. A connecting bolt group 10 and a column fastener 11 are provided between the upper welding assembly 2 and the mounting holes 9. The upper welding assembly 2 and the lower frame welding assembly 1 are connected into a whole through the mounting holes 9, the connecting bolt group 10, and the column fastener 11.

[0034] As a preferred embodiment, the guiding mechanism includes four slide blocks 12, which are slidably mounted on both ends of the connecting frame 8. Guide rods 13 are rotatably connected to the four slide blocks 12, and limit frames 14 are fixedly mounted on the guide rods 13. A locking assembly is provided between the guide rods 13 and the slide blocks 12. During the initial assembly process, the four slide blocks 12 are slid to the four corners of the connecting frame 8. Then, the guide rods 13 are rotated to make them vertically erect. The locking assembly then locks the guide rods 13. The limit frames 14 are adapted to the bottom of the front and rear frame 4. During the descent of the upper welding assembly 2, the front and rear frame 4 slides and adapts to the four limit frames 14, guiding the upper welding assembly 2 to descend.

[0035] As a preferred technical solution of this embodiment, the limiting frame 14 is provided with a connecting hole 15, and the limiting frame 14 is configured as a J-shaped frame. After the upper welding assembly 2 and the lower skeleton welding assembly 1 are spliced ​​together, the guide rod 13 is rotated to the horizontal position, and then the sliding slide 12 drives the limiting frame 14 to move towards the front and rear skeletons 4 of the upper welding assembly 2. When the bottom of the limiting frame 14 coincides with the bottom of the front and rear skeletons 4, the limiting frame 14 is fixedly connected to the front and rear skeletons 4 through the connecting hole 15, thereby further fixing the upper welding assembly 2. The long side of the J-shaped limiting frame 14 faces outward to avoid contact with the upper welding assembly 2 and the internal skeleton of the lower skeleton welding assembly 1.

[0036] As a preferred embodiment, the locking assembly includes a connector 16, four connector slots 17 at the bottom of the guide rod 13, two through slots 18 on the slide block 12, and a threaded knob 19 rotatably connected to one side of the connector 16. The threaded knob 19 is threadedly connected to the slide block 12. When the guide rod 13 is in a vertical or horizontal position, the through slots 18 and connector slots 17 overlap. At this time, by inserting the connector 16 through the connector slots 17 and through slots 18, the guide rod 13 can be fixed. At the same time, the threaded knob 19 rotates and is threadedly connected to the slide block 12 to fix the connector 16.

[0037] As a preferred technical solution in this embodiment, a flap assembly 20 is fixedly installed on the lower frame welding assembly 1, and an upward-opening door assembly 21 is provided on one side of the flap assembly 20. A curtain door assembly 22 is fixedly installed on the upper welding assembly 2, and protective plate assembly assemblies 23 are fixedly installed on both sides of the top of the upper welding assembly 2. A top cover 24 is fixedly installed on the top of the upper welding assembly 2, and an interior panel assembly 25 is provided between the upper welding assembly 2 and the lower frame welding assembly 1. The carriage is decomposed into multiple standardized functional modules (such as side panels, top panels, bottom panels, door frames, corner pillars, etc.). Each module is precision-machined, pre-assembled (such as pre-embedded cables, pre-installed interior parts), and quality-controlled in the factory. One of the biggest advantages is that the components are easy to replace after damage. Only the damaged module needs to be removed and replaced with a new prefabricated part, which makes maintenance convenient, low-cost, and quick.
