[0073] The present invention will be further described below in conjunction with the embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0074] A tractor hood, see Figure 2 , including an upper cover 1, a side panel 2, a front mesh panel 3, a headlight upper decorative cover 4, a headlight lower decorative cover 5 and a front connecting piece 6. A cover side fixing structure is provided at the lower part of both sides of the upper cover 1, and a cover fixing structure is provided at the front of both sides and the lower part of the front end; a side cover fixing structure is provided at the top of the side panel 2, a side panel fixing structure is provided at the front side, and a side piece fixing structure is provided at the bottom end of the front side; the side cover fixing structure is connected to the cover side fixing structure; the upper part of the headlight upper decorative cover 4 is provided with a cover fixing structure 4.1, and the lower part is provided with a cover plate fixing structure; the cover fixing structure 4.1 is connected to the cover fixing structure The front mesh panel 3 is provided with a plate side fixing structure on both sides, a plate cover fixing structure on the upper part, a front headlight lower decorative cover mounting hole and a lower decorative cover mounting structure in the middle part, and a plate fixing structure at the bottom; the plate side fixing structure is connected to the side panel fixing structure; the plate cover fixing structure is connected to the cover panel fixing structure; the lower decorative cover mounting structure is connected to the front headlight lower decorative cover 5; the front connecting member 6 is provided with a member side fixing structure at both ends, and a member plate fixing structure in the middle; the member side fixing structure is connected to the side member fixing structure; the member plate fixing structure is connected to the member plate fixing structure. The overall schematic diagram after the components are assembled is shown in FIG. Figure 1 .

[0075] In the present invention, except for the front mesh plate, the other components are made of non-metallic materials. A connecting structure is provided at the connection of each component. The connecting structure is integrally formed with each component. The components are directly connected through the connecting structure, eliminating the main metal bracket on the back. It is light in weight, simple in structure, low in cost and easy to install.

[0076] In an alternative embodiment of the present invention, see Figure 17 and 18 The tractor hood also includes upper and lower connecting beams 7, a headlight upper mounting bracket 8, a headlight lower mounting bracket 9 and a lower connecting reinforcement bracket 10; the front back of the upper cover 1 is provided with a BOSS column 17 ( Figure 12 The area shown in G-3) and BOSS column 18 ( Figure 12(area shown in G-4 in the middle); BOSS pillars 67 are located on the back of the center portion of the front connector 6; BOSS pillars 60 are located on the back of each side panel; BOSS pillars 20 are located on the back of the side panel 2; the upper and lower connecting beams 7 are bolted to BOSS pillars 17 at their upper ends and to BOSS pillars 67 at their lower ends; the upper headlight mounting bracket 8 is bolted to the upper and lower connecting beams 7 at its center portion and to BOSS pillars 18 at its ends; the lower headlight mounting bracket 9 is bolted to the upper and lower connecting beams 7 at its center portion; and the lower connecting reinforcement bracket 10 is bolted to BOSS pillars 67, 60, and 20. The upper and lower headlight mounting brackets are used to mount the headlight 12 in conjunction with the upper and lower headlight decorative covers 4 and 5. The upper and lower connecting beams, the lower connecting reinforcement bracket, the upper headlight mounting bracket and the lower headlight mounting bracket are made of metal materials and are formed by sheet metal bending to increase the structural strength of the middle part of the front end of the tractor hood and prevent deformation of the tractor hood; the upper and lower connecting beams also provide mounting points for the upper headlight mounting bracket and the lower headlight mounting bracket, ensuring the fixing strength of the upper headlight mounting bracket and the lower headlight mounting bracket.

[0077] Furthermore, the front mesh panel has honeycomb-shaped holes, and the material itself is relatively soft, resulting in poorer formability than conventional sheet metal, making complex structural designs impossible. The mounting holes in the front mesh panel also have lower precision than punched holes in ordinary metal sheets. These shortcomings result in poor controllability of the existing front mesh panel, making it difficult to design a matching structure with the lampshade, and resulting in poor detail quality after installation. The present invention addresses the existing problems of difficult matching and poor detail quality in the installation of tractor headlights, lampshade trim, mesh panels, and hoods by utilizing upper and lower connecting beams, a lower connecting reinforcement bracket, an upper headlight mounting bracket, and a lower headlight mounting bracket.

[0078] In an optional embodiment of the present invention, the lower end face of the middle part of the headlight upper mounting bracket 8 is fixedly connected to the upper and lower connecting beams 7 by an L-shaped bracket 1 8.2, and the lower part is fixedly connected to the front mesh plate 3 by an oblique bracket 1 8.1; the middle part of the headlight lower mounting bracket 9 is fixedly connected to the upper and lower connecting beams 7 by an L-shaped bracket 2 9.1, and the two sides are fixed to the lower connecting reinforcement bracket 10 by oblique bracket 2 9.2, and the upper part is fixedly connected to the front mesh plate 3 by an oblique bracket 3 9.3.

[0079] For details, see Figure 2 The tractor hood also includes a reinforcement frame 11. This frame is in an inverted U-shape, with its center portion adhesively bonded to the upper cover 1 and its sides to the outer side panels 2. This reinforcement frame increases the overall strength of the tractor hood and reduces deformation. Made of a lightweight non-metallic material, the reinforcement frame is molded with high precision. It is adhesively bonded to the upper cover and the back of the side panels, increasing the overall strength of the tractor hood and reducing deformation.

[0080] For details, see Figure 8 The tractor hood also includes two symmetrically arranged top cover mesh panels 1.1; the top cover 1 is provided with two mesh panel mounting holes; see Figure 9 , the top cover mesh plate 1.1 is provided with an annular glue groove 1.9 around it, and the glue groove 1.9 facilitates the top cover mesh plate 1.1 and the upper cover 1 to be fixed by gluing. Figure 10 The lower end surface of the upper cover 1 is provided with a plurality of BOSS columns and Z-shaped brackets 1.8 for fixing the top cover mesh panel 3; the BOSS columns surround the mesh panel mounting holes; one end of the Z-shaped bracket 1.8 is fixed to the BOSS column by screws, and the other end directly presses on the top cover mesh panel to further fix the top cover mesh panel. Figure 9 , the lower end surface of the upper cover 1 is also provided with an annular boss 1.10; the boss 1.10 is located inside the glue groove 1.9. The boss prevents glue from overflowing during bonding, which affects the surface quality. Since the top cover mesh plate is fixed by gluing, the glue curing time is relatively long. If there is no other auxiliary fixation, the top cover mesh plate is easy to fall off and move before the glue is cured, resulting in difficulty in ensuring assembly consistency, and the next step of assembly cannot be carried out until the gluing is completed. The present invention presses the top cover mesh plate by a Z-shaped bracket on the top cover mesh plate to ensure the fixation of the top cover mesh plate before the glue is cured, thereby ensuring the final assembly effect and avoiding problems such as the mesh plate falling off and moving. After gluing and fixing, the Z-shaped bracket can be disassembled and reused.

[0081] For details, see Figure 3 、 Figure 4 and Figure 5 , the cover side fixed structure includes BOSS column 12 1.2 ( Figure 12 The area shown in G-1), the positioning pin 1.3 and the limiting rib 1.4; see Figure 3 、 Figure 5 、 Figure 6 and Figure 7The side cover fixing structure includes a side cover fixing structure 1 2.1, a side cover fixing structure 2 2.2 and a flange 2.3 that cooperates with the limiting rib 1.4. The side cover fixing structure 1 2.1 is provided with a BOSS column mounting hole 12 that cooperates with the BOSS column 12 1.2, and the side cover fixing structure 2 2.2 is provided with a socket 2.4 that cooperates with the positioning pin 1.3; the BOSS column mounting hole 12 is preferably an oblong hole; the side cover fixing structure 1 2.1 and the BOSS column 12 1.2 are connected by bolts passing through the BOSS column mounting hole 12. The limiting rib 1.4 cooperates with the flange 2.3, and the positioning pin 1.3 cooperates with the socket 2.4 to limit the side panel and the upper cover in the thickness direction. The limiting rib 1.4 and the positioning pin 1.3 are provided with an oblique angle at the top. The side panel 2 is a thin plate part, the strength of the part itself is poor, and deformation is difficult to control. After assembly, the gap surface difference and clearance matching with the upper cover 1 are difficult to ensure. On the one hand, the present invention adopts oblong holes for the first and second BOSS column mounting holes, which reduces the requirements for matching accuracy of parts installation and reduces the difficulty of installing the upper cover and side panels. On the other hand, the positioning pins and limiting ribs on the upper cover ensure the matching accuracy of the upper cover and side panels in the left and right directions when installing. Among them, the front-end positioning pin is the main positioning pin, which can limit the matching accuracy of the top cover and side panels in the left and right directions and the front and back directions. The limiting ribs and the positioning pin structure have increased the bevel angle at the top to play the role of installation guide, which is convenient for the assembly of the two parts. The above structure ensures the installation matching accuracy of the two parts while reducing the difficulty of assembly, thereby improving the assembly quality and detail quality of the tractor hood.

[0082] For details, see Figure 8 、 Figure 11 and Figure 13 The connection between the upper cover 1 and the headlight upper decorative cover 4 is a thickened area 1.7. Figure 14 、 15 and 16, the cover fixing structure includes a plurality of BOSS columns 14 1.5 (( Figure 12 The area shown in G-2)) and the positioning pin 1.6; the cover fixing structure 4.1 is provided with a BOSS column mounting hole 14.2 that matches the BOSS column 14.1.5, and a positioning hole 4.3 that matches the positioning pin 1.6. The thickness of the thickened area is 15mm. The thickened area of ​​the upper cover increases the width of the matching surface between the decorative cover on the headlight and the upper cover, avoiding gaps in the matching position due to assembly errors, and no assembly adjustment is required, thereby improving the quality of structural matching after component assembly. The decorative cover on the headlight is made of plastic and is injection molded. The part itself is deformed. In order to avoid repeated adjustments during assembly with the upper cover due to deformation, the present invention can correct slight deformation of the decorative cover on the headlight through the positioning pin, thereby ensuring the matching accuracy with the upper cover. The positioning pin can also serve as an installation guide, reducing the difficulty of assembly.

[0083] In an optional embodiment of the present invention, the side panel fixing structure is BOSS column two or three; the panel side fixing structure is BOSS column mounting hole two or three that matches BOSS column two or three.

[0084] In an optional embodiment of the present invention, the side piece fixing structure is a BOSS column 26; the side piece fixing structure is a BOSS column mounting hole 26 that matches the BOSS column 26.

[0085] In an optional embodiment of the present invention, the cover plate fixing structure is BOSS column four-three; the plate cover fixing structure is BOSS column mounting hole four-three that cooperates with BOSS column four-three.

[0086] In an optional embodiment of the present invention, the headlight lower decorative cover (5) is provided with a BOSS column five-three; the lower decorative cover mounting structure is a BOSS column mounting hole five-three that matches the BOSS column five.

[0087] In an optional embodiment of the present invention, the component plate fixing structure is BOSS column six-three; the plate fixing structure is BOSS column mounting hole six-three that cooperates with BOSS column six-three.

[0088] Specifically, the side panel 2 is further provided with a side mesh panel 2.5, and a BOSS column 22 for mounting the side mesh panel is provided on the side panel. The side mesh panel and the BOSS column 22 are connected by bolts.

[0089] An embodiment of the present invention further provides a tractor, comprising the aforementioned tractor hood.

[0090] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
