Detailed Description

For a better understanding of the present application, reference will be made to the following drawings and to the accompanying drawings

The present application will be described in further detail with reference to the embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a cab according to an embodiment of the application.

The cab in this embodiment includes an outer cover plate 100 and an inner decoration plate 200, and the main bodies of the outer cover plate 100 and the inner decoration plate 200 are made of composite materials, for example, carbon fiber materials, or other composite materials, or materials formed by combining carbon fiber materials and other composite materials. The interior panel 200 includes a top plate and side plates positioned at both sides of the top plate, and the exterior panel 100 is covered outside the interior panel 200.

The cavity is formed between the outer cover plate 100 and the inner decoration plate 200, the cavity can comprise a wiring cavity, an electric circuit can be laid in the wiring cavity, and of course, connecting equipment required by the electric circuit or other electric elements required to be laid in the cavity can be arranged in the cavity, so that the electric circuit, the connecting equipment, the other electric elements and the like are in relatively closed and stable cavities, can keep stable forms, avoid being damaged by external environments, and can meet the clean layout of a cab. In addition, the interior panel 200 and the exterior panel 100 are partially cured as one body, i.e., a portion of the exterior panel 100 is spaced from the interior panel 200 to form a cavity, and a portion may be cured and attached to the interior panel 200.

Specifically, the inner side of the outer cover panel 100 may be provided with a protruding first connection portion, the outer side of the inner trim panel 200 may be provided with a protruding second connection portion, and the first connection portion and the second connection portion may overlap and be cured as one body. The first connecting portion may be directly formed on the outer cover plate 100, or may be a component that is separately disposed, and is subsequently cured into a whole with the outer cover plate 100; similarly, the second connecting portion may be directly molded to the interior panel 200, or may be a separate component, and then be cured integrally with the interior panel 200. The curing in this embodiment may be performed by wrapping the composite material at a position where the outer cover plate 100 and the inner decorative plate 200 are partially overlapped, and then curing the composite material in a curing oven.

The first and second connection parts may be variously constructed, for example, the middle part of the outer cover panel 100 may be recessed from the outside to the inside along the center line of the length direction to form the inwardly protruding first connection part, and the middle part of the top plate of the interior trim panel 200 may be recessed from the inside to the outside along the center line of the length direction to form the outwardly protruding second connection part, but of course, the first and second connection parts may be plural and discretely distributed to form the multi-point cure. It should be understood that the manner of local curing is not limited to providing the first connection portion and the second connection portion for overlapping, for example, the first connection portion may be directly overlapped to the outer surface of the interior panel 200 and then covered with the composite material for curing, whereas the second connection portion may be directly overlapped to the inner surface of the outer panel 100 and then covered with the composite material for curing, i.e. only the first connection portion or only the second connection portion may be provided. In actual setting, specific local curing positions and specific structural forms of the outer cover plate 100 and the inner decorative plate 200 can be flexibly set according to wiring arrangement requirements between the outer cover plate 100 and the inner decorative plate 200, so long as the outer cover plate 100 and the inner decorative plate 200 can be finally cured into a whole.

In this embodiment, the exterior panel 100 and the interior panel 200 may be preassembled together and then integrally placed into the curing oven, thereby forming the main architecture of the integrated cab.

Therefore, the outer cover plate 100 and the inner decoration plate 200 of the cab in the embodiment are processed into an integral structure, namely, an integral design is performed, intermediate transition connecting components can be omitted, a framework is not required, and the cab is simple to install, so that the purposes of integral design and integral weight reduction can be achieved.

Specifically, the first and second connection portions of the outer cover panel 100 and the inner trim panel 200 may be positioned and cured by first fasteners such as bolts, screws, rivets, and the like, which are conventional mechanical fastening structures. The fastening by the first fastening member can provide a predetermined positioning to ensure the curing effect, and can enhance the reliability of the final molded integrated structure of the exterior panel 100 and the interior panel 200.

Referring to fig. 2, fig. 2 is a schematic view illustrating the splicing of the outer cover plate 100 of the cab according to an embodiment of the application.

The outer cover 100 and the inner decorative panel 200 may be integrally formed, or may be integrally formed by splicing and resolidifying. That is, the outer cover panel 100 and the inner panel 200 may include a plurality of splice plate portions, and the splice plate portions may be overlapped and cured as one body. Therefore, when the cab with larger size is manufactured, the cab can be manufactured in a split mode and then spliced together, and therefore the requirement on a die can be reduced.

Further, at least one splice plate portion of the outer cover plate 100 is a first splice plate portion 100a, the first splice plate portion 100a includes at least one first splice side 100a1, the first splice side 100a1 forms a step plate portion 100a2, and a cross section of the first splice side 100a1 in fig. 2 is Z-shaped; and at least one splice plate portion of the outer cover plate 100 is a second splice plate portion 100b, the second splice plate portion 100b includes at least one second splice side 100b1, the second splice side 100b1 is provided with an inwardly bent plate portion 100b2, and in fig. 2, the second splice side 100b1 has an L-shaped cross section. When the two splice plates are spliced, the bent plate portion 100b2 is abutted against the step plate portion 100a2, the bent plate portion 100b2 and the step plate portion 100a2 are enclosed to form a concave portion 100e, and the concave portion 100e serves as a seam between the two adjacent splice plate portions, so that the inner member is not exposed, and the effect of beautiful appearance is achieved. In addition, the overlapping position of the bending plate portion 100b2 and the step plate portion 100a can be adjusted to adjust the overlapping region of the adjacent splice plate portions, thereby improving flexibility of splicing and being compatible with manufacturing errors of products.

In addition, referring back to fig. 2, the outer cover plate 100 further includes a transitional connection portion 100c and a second fastening member 100d, where a portion of the transitional connection portion 100c overlaps the step plate portion 100a2 and is fixed by the second fastening member 100d, specifically, a portion of the transitional connection portion 100c overlaps the inner side of the step plate portion 100a2, and may further adhere after overlapping, and another portion of the transitional connection portion 100c overlaps and adheres to the inner side of the second splice plate portion 100b, and the transitional connection portion 100c in fig. 2 is substantially Z-shaped to meet the overlapping requirement of the step plate portion 100a2 and the second splice plate portion 100 b.

In addition, the portion where the transitional connection portion 100c overlaps the step plate portion 100a2 and the portion where the transitional connection portion 100c adheres to the second splice plate portion 100b are all clad with the composite material and cured, that is, the integrated design of the first splice plate portion 100a and the second splice plate portion 100b is indirectly realized through the transitional connection portion 100 c. The second fastening member 100d is provided for the same purpose as the first fastening member described above, and serves the purpose of pre-positioning and reinforcing fastening before curing, and may be constructed in a conventional mechanical fastening structure such as a bolt, a screw, or a rivet. In addition, in fig. 2, the second splice plate portion 100b and the transitional coupling portion 100c are bonded only and are not fastened by fasteners, so that the fasteners are prevented from being exposed through the second splice plate portion 100b to maintain a cleaner outer surface.

In fig. 2, during processing and manufacturing, the step plate portion 100a2 of the first splice plate portion 100a may be bonded to the transitional connecting portion 100c, fastened by the second fastening member 100d, then the transitional connecting portion 100c is bonded to the second splice plate portion 100b, and the composite material is wrapped at the overlapping position and then cured in a curing oven. The transition connection portion 100c may be made of a composite material or a metal material, and mainly plays a role in transition connection, and the material is not particularly limited. It is understood that the bent plate portion 100b2 may not be provided when the concave portion 100e is not formed, and the stepped plate portion 100a2 may be directly joined to the inner side of the second splice plate portion 100b, and the transition connection portion 100c may not be provided at this time.
