However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0032] Combination Figure 1According to a specific embodiment of this application, a front bumper transition bracket is provided, comprising: a bracket body 1, wherein a plurality of front bumper fixing points 5 are provided on the bracket body 1, at least a portion of the front bumper fixing points 5 are spaced apart along a partial contour of the bracket body 1 in the circumferential direction, and the line connecting the projections of the plurality of front bumper fixing points 5 along the thickness direction of the bracket body 1 forms a first polygon; a plurality of frame fixing points 8 are provided on the bracket body 1, at least a portion of the frame fixing points 8 are spaced apart along a partial contour of the bracket body 1 in the circumferential direction, and the line connecting the projections of the plurality of frame fixing points 8 along the thickness direction of the bracket body 1 forms a second polygon, and the first polygon and the second polygon are at least partially overlapping; wherein, a height valve fixing point 9 is also provided on the bracket body 1, the projection of the height valve fixing point 9 along the thickness direction of the bracket body 1 is located within the first polygon, and an atmospheric temperature sensor fixing point 6 is also provided on the bracket body 1, the projection of the atmospheric temperature sensor fixing point 6 along the thickness direction of the bracket body 1 is located within the second polygon.

[0033] By ensuring that the first and second polygons formed by the projection lines connecting the front bumper fixing point 5 and the frame fixing point 8 at least partially overlap, the structural stability of the bracket body 1 can be enhanced. This layout allows for a more even distribution of force when the bracket is under load, thereby reducing local stress concentration and improving the overall load-bearing capacity and resistance to deformation.

[0034] By setting locating pins and mounting holes on the bracket body 1, and by spaced the fixing points along the circumferential contour, the assembly accuracy between the bumper and the vehicle frame can be significantly improved. This precise positioning helps ensure that the bumper is accurately positioned on the vehicle, avoiding safety hazards or functional problems caused by improper installation.

[0035] The height valve fixing point 9 and the atmospheric temperature sensor fixing point 6 are integrated inside the bracket body 1, and their projected positions are located within the first polygon and the second polygon, respectively. This achieves the integrated design of multiple components, reduces the number of parts and assembly complexity, lowers production costs and assembly time, and improves production efficiency.

[0036] Furthermore, the first polygon is a quadrilateral, and / or the second polygon is a quadrilateral.

[0037] Furthermore, there are at least two height valve fixing points 9, which are spaced apart along the height direction of the bracket body 1.

[0038] The distribution of the two height valve fixing points 9 better disperses the load from the height valve, avoiding structural damage caused by excessive force at a single point. This dual-point fixing method increases the stability of the connection between the bracket and the height valve, and improves the mechanical performance of the entire bumper connection transition bracket.

[0039] Specifically, the distribution of the height valve fixing points 9 in the height direction enhances the torsional resistance of the bracket body 1 in the height direction. When the vehicle travels on uneven roads, this design effectively resists the torsional force generated by road impacts, ensuring the stability of the height valve position and preventing performance degradation.

[0040] The spaced height valve fixing points 9 can absorb and disperse the vibration caused by vehicle movement to a certain extent, reduce the direct impact on the height valve, extend its service life, and also play a certain vibration buffering role for the bracket body 1.

[0041] The layout of the two fixed points provides greater flexibility in positioning the height valve, allowing for fine-tuning in the height direction to adapt to different frame structures and bumper designs, thus improving assembly adaptability and precision. Furthermore, a first reinforcing rib is provided between at least the two height valve fixed points 9, and weight-reducing holes 7 are provided on both sides of the first reinforcing rib in the width direction.

[0042] The addition of the first reinforcing rib can enhance the connection strength between the height valve fixing points 9, especially the bending and torsional resistance in the vertical and horizontal directions, which is particularly important for withstanding the dynamic loads during vehicle operation.

[0043] The reinforcing rib design can disperse stress, reduce stress concentration at the fixing point, and thus improve the fatigue resistance of the support under long-term use and repeated loads, extending its service life.

[0044] By setting weight-reducing holes 7 on both sides of the reinforcing ribs, the weight of the bracket can be reduced while ensuring structural strength. This plays an important role in improving the vehicle's fuel economy and handling performance. The weight-reducing holes not only reduce weight but also improve heat dissipation, especially for materials with good thermal conductivity like ductile iron. This helps reduce thermal stress on the bracket during operation and improves its stability under extreme temperature conditions.

[0045] The design of the weight-reducing holes facilitates the flow of molten iron during the casting process, reduces the possibility of casting defects, and improves the dimensional accuracy and surface quality of the product.

[0046] Optionally, traditional metal reinforcing ribs can be replaced with composite material reinforcing ribs, such as carbon fiber or glass fiber. Composite materials are not only high in strength and lightweight, but can also be customized to better adapt to stress analysis under different working conditions, while reducing the overall weight of the support structure.

[0047] Furthermore, the bracket body 1 is also provided with two front bumper positioning points 10. The two front bumper positioning points 10 are arranged opposite each other along the height direction. Two of the multiple front bumper fixing points 5 are located on the top side of the bracket body 1, and one of the front bumper positioning points 10 is located between the two front bumper fixing points 5 on the top side of the bracket body 1.

[0048] Two opposing front bumper positioning points 10 provide vertical positioning, ensuring the bumper is vertically aligned during installation and avoiding gap issues or assembly difficulties caused by inaccurate positioning. This high-precision positioning is crucial for ensuring the aesthetics and functionality of the vehicle's front end.

[0049] Setting the positioning point between two fixed points allows the fixed points to serve as additional supports, enhancing the structural stability at the positioning point and preventing deformation or displacement under lateral forces, thus ensuring the bumper's sturdiness and reliability after installation.

[0050] The two front bumper fixing points 5 on the top side and the positioning point in the middle form a stable triangular structure. This layout can optimize the force distribution of the bumper on the bracket body 1 and reduce structural damage caused by excessive local force.

[0051] Furthermore, the projection of one of the multiple front bumper fixing points 5 along the thickness direction of the bracket body 1 is located within the second polygon, and the front bumper fixing point 5 with the projection located within the second polygon is connected to the multiple frame fixing points 8 by a second reinforcing rib 4.

[0052] By setting a second reinforcing rib 4 between the front bumper fixing point 5 and the frame fixing point 8, which are projected within the second polygon, the connection strength and rigidity between the bumper and the frame can be significantly improved, thereby enhancing the stability of the overall structure.

[0053] The layout of the second reinforcing rib 4 helps to optimize the force transmission path, so that the external impact force received by the front bumper can be more effectively distributed to the frame, reducing the damage to the bumper itself, while improving the bumper's impact resistance.

[0054] The design of the reinforcing ribs can improve the shock resistance and fatigue resistance of the bracket body 1, especially when the vehicle encounters uneven road surfaces during driving, it can effectively reduce the impact of vibration and impact on the connection between the bumper bracket and the frame.

[0055] The addition of the second reinforcing rib 4 helps to improve the material flowability and cooling performance during the casting process, reduce casting defects, and improve the dimensional accuracy and structural consistency of the castings.

[0056] By reasonably arranging the reinforcing ribs, while ensuring the structural strength, the weight distribution can be optimized, avoiding structural instability or reduced vehicle handling performance caused by weight concentration. The arrangement of the reinforcing ribs can not only enhance the structural strength but also be used as additional fixing points for other functional components such as atmospheric temperature sensors and height valves, further improving the component integration and space utilization rate.

[0057] Furthermore, at least one vehicle frame positioning pin is provided on the bracket body 1, and the vehicle frame positioning pin is arranged adjacent to the vehicle frame fixing point.

[0058] Furthermore, the circumferential contour of the bracket body 1 is a regular regular polygon, and the thickness of at least part of the side edges of the bracket body 1 is higher than the thickness of the middle area of the bracket body 1.

[0059] Furthermore, the front bumper transition bracket is integrally cast and formed by ductile iron. Figure 1 The upper frame 2 and the lower frame 3 are also shown.

[0060] The front bumper transition bracket uses a ductile iron bracket to replace the conventional metal stamping part combination structure; the front bumper transition bracket integrates the front bumper transition bracket, height valve bracket, atmospheric temperature sensor bracket, etc., realizing the combination of multiple parts into one. The whole adopts a frame-type closed structure, equipped with positioning pins and positioning installation holes, realizing the precise transition positioning and auxiliary assembly between the front bumper and the vehicle frame. The bracket is highly integrated, with a compact structure and high strength.

[0061] For the front bumper transition bracket of the present utility model, the ductile iron process is adopted, the thickness of the bracket main body is 12 mm, the yield limit of the product is 260 - 280 MPa, the tensile strength is 390 - 450 Mpa, and the elongation rate reaches 8 - 10%. The product has high yield and high ductility.

[0062] The upper and lower frames of the front bumper form a complete closed transition bracket frame structure, showing a square shape; the middle part of the front bumper transition bracket is in a cross shape, together with the closed front bumper frame structure, forming a grid shape, which can effectively increase the overall stiffness and strength of the bracket. The closed structure is beneficial to the fluidity of the molten iron during the casting production process, and at the same time helps the anti-deformation ability of the product and improves the dimensional accuracy of the product.

[0063] The main frame of the front bumper transition bracket is provided with multiple main fixing points and reinforcing ribs. The main frame of the front bumper bracket adopts a semi-enclosed closed structure and is internally strengthened by cross-shaped reinforcing ribs, effectively improving the strength of the front bumper bracket while reducing the part weight.

[0064] The main frame of the front bumper transition bracket is equipped with an atmospheric temperature sensor fixing point and a height valve fixing point. The atmospheric temperature sensor fixing point provides support for fixing the atmospheric temperature sensor and is connected by screw thread. The height valve fixing point provides support for fixing the height valve.

[0065] The front bumper is bolted to the mounting points and the front bumper bracket, and the positioning holes on the front bumper mate with the positioning pins on the front bumper bracket to improve the positioning accuracy. Similarly, the frame is bolted to the mounting points, and the frame fixing pins mate with the positioning holes on the frame to improve positioning accuracy and facilitate assembly and disassembly, thus enhancing assembly convenience.

[0066] The bumper transition bracket is made of ductile iron and integrates functions such as height valve bracket and atmospheric temperature sensor bracket.

[0067] The bumper transition bracket forms a complete and enclosed frame structure. The main body is in the shape of a grid, which can effectively increase the overall rigidity and strength of the bracket. At the same time, the enclosed structure is conducive to the liquid flow during the casting process, and also helps the product's resistance to deformation and improves the product's dimensional accuracy.

[0068] The main frame of the front bumper transition bracket adopts a semi-enclosed structure with internal cross-shaped reinforcing ribs to strengthen the structure, effectively improving the strength of the mudguard bracket while reducing the weight of the parts.

[0069] A complete technical solution can be achieved by simply removing the atmospheric temperature sensor fixing structure from the bumper connection transition bracket; or by simply adding some fixing points with smaller loads, such as an air horn bracket.

[0070] According to another aspect of the present invention, a vehicle is provided, including a front bumper transition bracket, wherein the front bumper transition bracket is the aforementioned front bumper transition bracket.

[0071] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: A front bumper connecting transition bracket made of ductile iron is designed, integrating functions such as a front bumper transition bracket, a height valve bracket, and an atmospheric temperature sensor bracket. By setting positioning pins and positioning mounting holes, precise transition positioning and auxiliary assembly between the front bumper and the vehicle frame are achieved. The overall structure adopts a frame-type closed structure, with internal structural reinforcement through cross-shaped reinforcing ribs. The technical problems solved include improving the assembly accuracy of the bumper connecting transition bracket, reducing its size, increasing structural strength, and achieving the integration of multiple functions to meet the universality requirements between parts of different vehicle models, reducing the number of parts, and ensuring the reliability of the front bumper fixation and ease of assembly. This application has the following technical effects: high assembly accuracy, accurate positioning, and improved assembly convenience. Small size and compact structure, which helps reduce space occupation; high strength, the ductile iron process gives the bracket high yield strength and high ductility, effectively improving overall rigidity and strength; the addition of weight-reducing holes helps reduce the weight of the parts while maintaining high strength; integrating multiple functions, such as fixing the atmospheric temperature sensor and the height valve, achieves multi-part integration, reducing design and modification costs.
