[0033] This application provides a lightweight front bumper transition bracket, such as Figures 1 to 3 As shown, the transition bracket includes a first module 100, a second module 200 and a third module 300 connected in sequence. The first module 100 connects the frame 500 and the front bumper 400 at the same time. The third module 300 connects the front bumper 400. The first module 100 includes a first connector and a second connector that surround each other, and the first connector and the second connector are respectively connected to the frame 500 and the front bumper 400.
[0034] This application optimizes the front bumper transition bracket, reducing its weight while improving connection stability, thus achieving a lightweight design and lowering production costs. The transition bracket consists of three sections: a first module 100, a second module 200, and a third module 300, which enhances its support strength and fatigue life.
[0035] In one embodiment, the first module 100 is further provided with a reinforcing member, which is fixedly connected to the second connecting member. This application provides a reinforcing member, which is fixedly connected to the second connecting member, to enhance the strength of the second connecting member, which is connected to both the frame 500 and the front bumper 400. This helps to strengthen the stability of the connection between the transition bracket and the frame 500 and the front bumper 400, and improves the connection support strength of the transition bracket.
[0036] Furthermore, the first connecting member includes a first bent plate 101, the second connecting member includes a second bent plate 102, the first bent plate 101 is L-shaped, the second bent plate 102 is rectangular, and the reinforcing member includes a reinforcing plate 103 whose two ends are connected to the inner wall of the second bent plate 102.
[0037] Furthermore, the second bending plate 102 includes a rectangular cavity 1021 for accommodating a portion of the second module 200. The rectangular cavity 1021 has an opening 1022 through which the second module 200 passes. The first bending plate 101 is fixedly connected to the outer wall of the opening 1022. The rectangular cavity 1021 formed by the second bending plate 102 provides a fixed area for the connection between the second module 200 and the first module 100. At the same time, by setting the rectangular cavity 1021, it is beneficial to reduce the weight of the first module 100 and provide sufficient operating space for the connection between the first module 100 and the second module 200.
[0038] The enclosure of the first bending plate 101 and the second bending plate 102 is achieved by the first bending plate 101 enclosing the opening 1022 of the second bending plate 102, thereby strengthening the opening 1022 of the second bending plate 102 and improving the connection strength of the transition bracket.
[0039] Preferably, the reinforcing plate 103 is connected to the adjacent inner walls of the second bent plate 102 to form a triangular support beam. The two ends of the reinforcing plate 103 are respectively fixed to the two adjacent inner walls of the second bent plate 102, so that the reinforcing plate 103 and the two adjacent side walls of the second bent plate 102 jointly form a triangular reinforcing structure, improving the stability of the second bent plate 102 when connected to the frame 500 and the front bumper 400. Furthermore, since the first bent plate 101 is not provided on this side, by providing the reinforcing plate 103 inside the rectangular cavity 1021, it is beneficial to maintain a strength balance between the side connecting the first bent plate 101 and the side where the reinforcing plate 103 is provided.
[0040] Furthermore, such as Figure 3 As shown, a weight-reducing port 1023 is added to the top of the second bending plate 102 to further reduce the weight of the second bending plate 102, and its top does not need to be connected to other components.
[0041] In one embodiment, the second module 200 includes a bent circular tube 201, which has multiple rounded corners and a connection position that is fixedly connected to the first module 100.
[0042] Furthermore, the connection positions include a first connection position 104 and a second connection position 105 that are fixedly connected to the adjacent inner wall of the second connector. The bent circular tube 201 is welded and fixed to the second connector at the first connection position 104 and the second connection position 105. The second bent plate 102 is welded to the bent circular tube 201 at different angles at the first connection position 104 and the second connection position 105 to ensure the stability and reliability of the connection between the bent circular tube 201 and the second bent plate 102.
[0043] Preferably, the bent circular tube 201 is a hollow circular tube, which helps to reduce the weight of the transition support and further achieve a lightweight design.
[0044] In one embodiment, the third module 300 includes a third connector 301. The inner wall of the third connector 301 is provided with a third connection position 302 and a fourth connection position 303 that are fixedly connected to the bent circular tube 201. The bent circular tube 201 is welded to the third connector 301 at the third connection position 302 and the fourth connection position 303. The third module 300 and the second module 200 are fixed by welding at the third connection position 302 and the fourth connection position 303.
[0045] Preferably, the third connector 301 is provided with an oblong hole 304, and the bent round tube 201 is plug-welded to the third connector 301 at the oblong hole 304. The connection rigidity between the second module 200 and the third module 300 is improved by providing the oblong hole 304 for connection.
[0046] Furthermore, the third connector 301 is provided with a positioning hole 3011 for connecting with the front bumper 400. The third connector 301 is connected to the inner wall of the front bumper 400 at the positioning hole 3011.
[0047] It is understood that the first module 100, the second module 200 and the third module 300 all include fasteners to achieve fixed connections at corresponding positions. The selection of fasteners is easy for those skilled in the art to set, and the positions of the fasteners are easy to obtain by referring to the diagrams, so they will not be elaborated here.
[0048] In one specific implementation, such as Figure 1 , Figure 2 As shown, the first module 100, the second module 200, and the third module 300 are all made of low-carbon steel, which is low in cost and easy to weld, facilitating the overall forming of the transition bracket. The first bending plate 101 and the second bending plate 102 are 4mm thick, and the reinforcing plate 103 is 3mm thick. Two 11mm connecting holes are vertically arranged on the first bending plate 101 for connection to the frame 500. The second bending plate 102 has three triangularly distributed connecting holes for connection to the front bumper 400; one is a waist-shaped connecting hole with a minimum diameter of 11mm, and the other two are circular holes with a diameter of 11mm.
[0049] The material thickness of the bent round tube 201 is 2mm. The bent round tube 201 has 3 rounded corners with a half-angle of r175mm, which increases the vertical stiffness of the second module 200 and improves the structural strength.
[0050] Meanwhile, the third connector 301 is a stamped plate with a thickness of 2mm. The positioning hole 3011 provided here has a diameter of 11mm.
[0051] It is understandable that although the various types of connection holes are not individually labeled in the figures, their locations can be easily determined by combining the above description and the accompanying drawings, and are easy for those skilled in the art to understand and set.
[0052] Furthermore, the transition support in this application, after finite element strength and fatigue calculations, meets the strength, fatigue usage, and design requirements. Compared with traditional supports, it is lighter and cheaper, making it easier to promote and use. See Table 1 for details.
