Description

Technical Field

[0001] This utility model relates to the field of tractor parts processing technology, specifically to a tractor engine cover support structure. Background Technology

[0002] Tractors play a crucial role in agricultural production and related operations. The hood not only protects key internal components such as the engine, but also affects the overall appearance and aerodynamic performance of the tractor. As an important component for the installation and support of the hood, the rationality of its design directly affects the stability, maintainability, and compatibility with other tractor components.

[0003] Currently, existing tractor hood support structures have several shortcomings. Some support structures are poorly designed, resulting in inadequate hood installation stability and difficulty in effectively resisting vibrations and external impacts during operation. This leads to hood loosening and displacement, affecting the protection of internal components and potentially causing damage at the connection between the hood and the support structure due to prolonged vibration, thus shortening its service life. Furthermore, existing support structures also lack ease of installation and removal. The complex installation structure makes disassembly and installation cumbersome for maintenance personnel when inspecting internal components such as the engine, consuming significant time and labor costs and reducing the efficiency of routine tractor maintenance.

[0004] In addition, the existing support structure is inefficient in terms of space utilization and component integration, and lacks a reasonable layout design. This results in unreasonable installation positions for auxiliary support components such as gas springs, affecting the smoothness of opening and closing the hood. Furthermore, there are no suitable installation positions for electronic control units such as ECUs, leading to messy wiring inside the tractor, increasing the risk of circuit failures, and hindering subsequent troubleshooting and maintenance.

[0005] Therefore, there is an urgent need for a new type of tractor hood support structure that can effectively solve the problems of insufficient stability, inconvenient installation and disassembly, and unreasonable space utilization in the existing technologies. Utility Model Content

[0006] The purpose of this invention is to provide a tractor hood support structure that is structurally stable and has a long service life, in order to address the above problems.

[0007] To achieve the above objectives, this utility model discloses a tractor hood support structure, including a support frame arranged in a vertical direction. The structure is characterized by a hood mounting seat arranged in a horizontal direction at the upper end of the support frame. The hood mounting seat has a support plate for supporting the hood, and the support plate is vertically connected to the support frame. A positioning connecting frame is provided on the support frame below the hood mounting seat. Gas spring mounting seats are provided on the left and right sides of the support frame between the positioning connecting frame and the hood mounting seat.

[0008] With the above structure, a stable vertical support system is formed by the vertical support frame and the horizontal hood mounting base, which effectively disperses the weight of the hood and external impact and improves the resistance to deformation. The support plate fits against the inner wall of the hood, the positioning connecting frame achieves precise docking with the engine housing, and the gas spring mounting base provides assistance for opening the hood. All three together improve the installation stability and ease of operation of the hood.

[0009] Preferably, the support frame includes two spaced-apart vertical beams, with a supporting crossbeam connected to the lower end of each beam. The hood mounting base is fixed to the upper end of the two vertical beams, and the body of each vertical beam near its lower end is bent forward. The frame structure with double vertical beams and supporting crossbeams enhances torsional stiffness, while the forward bending design of the lower ends of the vertical beams optimizes the force transmission path, reduces stress concentration, and extends the structural lifespan.

[0010] Preferably, the hood mounting base includes a horizontal plate connected to the upper ends of two vertical beams. The rear end edge of the horizontal plate extends to the rear side of the vertical plane containing the rear sidewall of the vertical beams. Reinforcing ribs connected to the lower end surface of the horizontal plate are respectively provided on the front end surfaces of the two vertical beams below the horizontal plate. Connecting bushings are respectively provided at the left and right ends of the upper end surface of the horizontal plate. The central axes of the two connecting bushings are located on the same straight line, and the two connecting bushings are fixed to the horizontal plate by a fixed base. A rectangular notch is provided on the horizontal plate between the two connecting bushings. Extending the rear end of the horizontal plate to increase the support area provides support for the support plate, while the reinforcing ribs improve bending resistance. The connecting bushings provide a precise rotation fulcrum, ensuring smooth opening and closing of the hood. The rectangular notch reduces weight and can also serve as a wiring harness channel or maintenance window, improving space utilization.

[0011] Preferably, the support plate is a rectangular baffle structure, with its upper side and left and right sides abutting against the inner sidewall of the machine hood. A positioning mounting opening is provided in the middle of the support plate, and a connecting plate integrally bent into shape is provided at the upper edge of the positioning mounting opening. The connecting plate is perpendicular to the support plate and fixed to the machine hood mounting base. The upper edge of the positioning mounting opening is located at the upper end face of the machine hood mounting base. By having the support plate abutting against the inner wall of the machine hood on three sides, surface contact support is provided, reducing localized stress. Furthermore, the upper edge of the positioning mounting opening is flush with the machine hood mounting base, improving installation stability and reducing the likelihood of deformation.

[0012] Preferably, the positioning connecting frame is an L-shaped baffle formed by integrally bending a rectangular plate. The left and right ends of the vertical plate of the positioning connecting frame are fixed to the two vertical beams of the support frame, respectively. The horizontal plate of the positioning connecting frame extends towards the front of the support frame, and reinforcing ribs are provided at the corners of the horizontal and vertical plates to connect them. Positioning connecting plates and positioning connecting posts for connection to the engine housing are respectively located at the left and right ends of the positioning connecting frame near the bottom surface of the horizontal plate. This L-shaped positioning connecting frame, with its reinforced structure through reinforcing ribs and integrated positioning connecting plates and positioning connecting posts, can achieve reliable multi-point connection with the engine and effectively reduce vibration transmission.

[0013] Preferably, the front end face of the vertical plate of the positioning connecting frame is provided with an ECU mounting seat extending forward. The ECU mounting seat includes a connecting plate fixed to the vertical plate and an extension plate parallel to the horizontal plate. By integrating the ECU mounting seat into the positioning connecting frame, the electronic control unit can be installed near the engine, effectively shortening the signal transmission distance.

[0014] Preferably, the positioning connecting plate is a strip-shaped plate structure, arranged vertically and parallel to the left side of the support frame. The positioning connecting column includes a columnar support body vertically arranged on the lower end face of the transverse plate. The upper end of the columnar support body is provided with a bolt for fixing to the transverse plate, and the lower end of the columnar support body is provided with a docking cylinder with the same axial direction as the main body. The strip-shaped positioning connecting plate can provide multiple bolt hole options to adapt to different engine housing interfaces. The combination of the columnar support body and the docking cylinder enables rapid positioning and fastening and improves assembly efficiency. In addition, the prism-shaped columnar support body can also increase shear resistance and evenly distribute the vibration load transmitted by the engine.

[0015] Preferably, the columnar support is prismatic in shape and the outer wall of the mating cylinder is threaded. The threaded connection with the engine is achieved by mating the cylinder with the thread, which allows for repeated disassembly and provides higher connection strength compared to traditional welding or snap-fit ​​connections.

[0016] Preferably, the gas spring mounting base includes a rectangular connecting block mounted on a support frame. The connecting block has an L-shaped positioning plate integrally bent into shape. The corner of the L-shaped positioning plate is fitted against the outer end face and rear end face of the rectangular connecting block and extends towards the front of the support frame. Reinforcing ribs connecting the front end face of the rectangular connecting block and the side wall of the L-shaped positioning plate near the support frame are provided. Reinforcing ribs connecting to the side wall of the support frame are provided on the bottom surface of the rectangular connecting block. The front end plate of the L-shaped positioning plate has mounting holes for installing the gas spring. The multi-angle reinforcing rib design of the L-shaped positioning plate and the rectangular connecting block provides a stable gas spring fulcrum and ensures uniform opening force and easy operation of the machine cover.

[0017] Preferably, an extension plate perpendicular to the side edge of the support plate is provided on the side edge of the inner wall of the hood, and the extension plate is provided on the front and rear side walls of the support plate. The extension plate increases the contact area with the inner wall of the hood, especially strengthens the support of the front and rear edges and reduces the risk of warping and deformation of the hood. The extension plate usually uses a cushioning material (such as rubber strips) to provide cushioning when the hood is closed, effectively reducing collision noise and protecting the paint surface.

[0018] In summary, the beneficial effects of this utility model are as follows: the structure of this utility model is stable and not easy to crack or deform. The vertical support frame and the horizontal hood mounting base form a stable vertical support system, which effectively disperses the weight of the hood and external impact and improves the resistance to deformation. The support plate fits against the inner wall of the hood, the positioning connecting frame achieves precise docking with the engine housing, and the gas spring mounting base provides assistance for opening the hood. All three of these factors work together to improve the installation stability and ease of operation of the hood. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, this utility model includes a support frame 1 arranged vertically, and a hood mounting seat 2 arranged horizontally at the upper end of the support frame 1. In design, the support frame 1 includes two spaced vertical beams, and a supporting horizontal beam connected to the two vertical beams at their lower ends. The support frame 1 is fixed to the machine frame by fixing bolts on the supporting horizontal beam. The hood mounting seat 2 is fixed to the upper ends of the two vertical beams, and the lower ends of the vertical beams are bent forward. This frame structure with double vertical beams and supporting horizontal beams enhances torsional stiffness, while the forward bending design of the lower ends of the vertical beams optimizes the force transmission path, reduces stress concentration, and extends the structural lifespan. In manufacturing, the hood mounting seat 2 includes a horizontal plate 6 connected to the upper ends of the two vertical beams, with the rear edge of the horizontal plate 6 facing... The vertical plane containing the rear side wall of the vertical beam extends to the rear, and the support area is expanded by extending the rear end of the horizontal plate 6 to provide support for the support plate 3. Reinforcing ribs connected to the lower end face of the horizontal plate 6 are respectively provided on the front end face of the two vertical beams below the horizontal plate 6. Connecting bushings 7 are respectively provided at the left and right ends of the upper end face of the horizontal plate 6. The central axes of the two connecting bushings 7 are located on the same straight line and the two connecting bushings 7 are fixed to the horizontal plate 6 by the fixed base 8. At the same time, a rectangular notch 9 is provided on the horizontal plate 6 between the two connecting bushings 7. The reinforcing ribs can improve the bending resistance, and the connecting bushings 7 provide a precise rotation fulcrum to ensure smooth opening and closing of the cover. The design of the rectangular notch 9 can reduce weight and can also serve as a wire harness channel or maintenance window and improve space utilization.

[0027] like Figure 1 , Figure 2 As shown, a support plate 3 for supporting the machine cover is provided on the machine cover mounting base 2, and the support plate 3 is vertically connected to the support frame 1. The support plate 3 is usually a rectangular baffle structure. The upper side and the left and right sides of the support plate 3 are attached to the inner side wall of the machine cover and are adapted to the shape of the inner cavity of the machine cover cross section. In this way, by the support plate 3 being attached to the inner wall of the machine cover on three sides, surface contact support can be provided and local stress can be reduced. A positioning mounting port 10 is also provided in the middle of the support plate 3. In the design, a connecting plate 11 integrally bent is also provided at the upper edge of the positioning mounting port 10. The connecting plate 11 is perpendicular to the support plate 3 and is fixed to the horizontal plate 6 of the machine cover mounting base 2 by bolts. Moreover, the upper edge of the positioning mounting port 10 is located on the upper edge of the machine cover mounting base 2. At the end face position, the upper edge of the positioning mounting port 10 is flush with the hood mounting base 2, which improves the stability of the installation and further provides stable support for the hood. On the side edge of the support plate 3 that fits against the inner wall of the hood, there is also a hood extension plate 21 that is perpendicular to the side edge of the support plate 3. The hood extension plate 21 is fixed to the front and rear side walls of the support plate 3. It can be welded or inserted. The installation method of the hood extension plate 21 is a known structure and will not be described in detail here. In this way, the hood extension plate 21 can increase the contact area with the inner wall of the hood, especially strengthen the support of the front and rear edges and reduce the risk of warping and deformation of the hood. Usually, the extension plate uses a cushioning material such as rubber strips that can be embedded, which can provide cushioning when the hood is closed, effectively reducing collision noise and protecting the paint surface.

[0028] like Figure 1 , Figure 2As shown, a positioning connection frame 4 is provided on the support frame 1 below the engine hood mounting base 2. The positioning connection frame 4 is an L-shaped baffle formed by integrally bending a rectangular plate. In the design, the left and right ends of the vertical plate 13 of the positioning connection frame 4 are fixed to the front end faces of the two vertical beams of the support frame 1 by fixing bolts. The fixing bolts usually pass through the vertical plate 13, the positioning connection frame 4, and the support plate 3 and connect the three together. The horizontal plate 12 of the positioning connection frame 4 extends to the front side of the support frame 1, and the corner of the horizontal plate 12 and the vertical plate 13 is provided with a reinforcing rib connecting the two. The positioning connection frame 4 is provided with a positioning connection plate 14 and a positioning connection column 15 connected to the engine housing at the left and right ends near the bottom surface of the horizontal plate 12. In this way, the L-shaped positioning connection frame 4 is reinforced by reinforcing ribs, and the positioning connection plate 14 and the positioning connection column 15 are integrated to achieve reliable multi-point connection with the engine and effectively reduce vibration transmission. During manufacturing, the positioning connecting plate 14 is a strip-shaped plate structure, vertically positioned and parallel to the left side of the support frame 1. The aforementioned positioning connecting column 15 includes a columnar support vertically positioned on the lower end face of the transverse plate 12. Typically, the upper end of the columnar support is fitted with bolts for fixing to the transverse plate 12, and the lower end of the columnar support has a mating cylinder 17 aligned with the axis of the main body. This allows the strip-shaped positioning connecting plate 14 to provide multiple bolt hole options, adapting to different engine housing interfaces. The combination of the columnar support and the mating cylinder 17 enables rapid positioning and fastening, improving assembly efficiency. Furthermore, the prism-shaped columnar support increases shear resistance and evenly distributes the vibration load transmitted by the engine. During installation, the prism-shaped columnar support has threads on the outer wall of the mating cylinder 17, achieving a threaded connection with the engine through the threaded mating cylinder 17. Compared to traditional welding or snap-fit ​​connections, this allows for repeated disassembly and provides higher connection strength.

[0029] An ECU mounting base 16 extending forward is provided on the front end face of the vertical plate 13 of the positioning connecting frame 4. The ECU mounting base 16 includes a connecting plate 11 fixedly connected to the vertical plate 13 and an extension plate parallel to the horizontal plate 12. By integrating the ECU mounting base into the positioning connecting frame 4, the electronic control unit can be installed near the engine, which can effectively shorten the signal transmission distance.

[0030] like Figure 1 , Figure 2As shown, gas spring mounting seats 5 are also provided on the left and right sides of the support frame 1 between the positioning connecting frame 4 and the machine cover mounting seat 2. In the design, the gas spring mounting seat 5 includes a rectangular connecting block 18 set on the support frame 1. An L-shaped positioning plate 19 formed by integral bending is fixed on the connecting block. The L-shaped positioning plate 19 is attached to the outer end face and rear end face of the rectangular connecting block 18 at the corner and extends towards the front side of the support frame 1. In the manufacturing process, the front end face of the rectangular connecting block 18 and the side wall of the L-shaped positioning plate 19 near the support frame 1 are provided with reinforcing ribs connecting the two. The bottom surface of the rectangular connecting block 18 is provided with reinforcing ribs connected to the side wall of the support frame 1. The front end plate of the L-shaped positioning plate 19 is provided with mounting positioning holes 20 for installing gas springs. In this way, the multi-angle reinforcing rib design of the L-shaped positioning plate and the rectangular connecting block 18 can provide a stable gas spring fulcrum and ensure uniform opening force of the machine cover and easy operation.
