Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an integrated kettle bracket structure that improves load-bearing capacity. Background Technology

[0002] In the integrated design of automotive components, the water bottle holder, as a key component connecting the water bottle to the vehicle frame, must simultaneously meet assembly space constraints and load-bearing requirements. Existing integrated water bottle holders are often designed with a bent structure to avoid surrounding structural components, and the bend is a stress concentration area.

[0003] During durability testing of the new vehicle model, the bending structure fractured due to prolonged exposure to the weight of the kettle and road surface stress. Analysis revealed the cause to be:

[0004] Stress concentration at the bend resulted in a maximum Mises stress of 462.848 MPa, exceeding the yield strength of the material (Q420 steel) (420 MPa), which triggered plastic deformation and cracks. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated kettle support structure with improved load-bearing capacity. It solves the problem that existing integrated kettle supports, which are often designed with a bent structure to avoid surrounding structural components, suffer from stress concentration at the bend, leading to fracture failure under long-term loads from the kettle's weight and road surface stress.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated kettle support structure with improved load-bearing capacity, comprising a support body, a support plate connected to the top of the support body, a support profile fixedly connected at the angle between the support body and the support plate, and a first reinforcing rib and a second reinforcing rib embedded at the connection between the support body and the support plate.

[0007] Preferably, the main body of the bracket is U-shaped, and there are two support plates, which are integrally formed with the two top ends of the main body of the bracket.

[0008] Preferably, the first reinforcing rib and the second reinforcing rib are respectively embedded in the two vertical parts of the U-shaped support body.

[0009] Preferably, the outer edge of the support body is provided with a edging.

[0010] Preferably, the main body of the bracket has a through-hole for mounting a kettle.

[0011] Preferably, the support plate has through-holes for mounting brackets.

[0012] Its beneficial effects are as follows:

[0013] 1. This integrated kettle support structure, which improves load-bearing capacity, reduces the maximum Mises stress of the support body from 462.848MPa to 254.7MPa by adding a supporting profile at the angle between the support body and the support plate, and embedding a first reinforcing rib and a second reinforcing rib at the connection. This is lower than the yield strength of Q420 steel (420MPa), and the maximum stress of the supporting profile is 129.46MPa, which is lower than its yield strength (235MPa), effectively preventing fracture failure.

[0014] 2. This integrated kettle support structure, which improves load-bearing capacity, is optimized by only adding supporting profiles locally. It does not require changes to the overall structure and assembly relationship of the main body of the support, thus avoiding the costs of mold replacement and re-molding caused by major modifications.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model discloses an integrated kettle support structure to improve load-bearing capacity, according to the attached... Figure 1 As shown, the bracket includes a support body 1, a support plate 2 connected to the top of the support body 1, a support profile 3 fixedly connected at the angle between the support body 1 and the support plate 2, and a first reinforcing rib 4 and a second reinforcing rib 5 embedded at the connection between the support body 1 and the support plate 2.

[0026] By adding a support profile 3 at the angle between the support body 1 and the support plate 2, and embedding a first reinforcing rib 4 and a second reinforcing rib 5 at the connection, the maximum Mises stress of the support body 1 is reduced from 462.848MPa to 254.7MPa, which is lower than the yield strength of Q420 steel (420MPa). The maximum stress of the support profile 3 is 129.46MPa, which is lower than its yield strength (235MPa), effectively preventing fracture failure.

[0027] By adding a support profile 3 at the angle between the support body 1 and the support plate 2, and embedding a first reinforcing rib 4 and a second reinforcing rib 5 at the connection, the maximum Mises stress of the support body 1 is reduced from 462.848MPa to 254.7MPa, which is lower than the yield strength of Q420 steel (420MPa). The maximum stress of the support profile 3 is 129.46MPa, which is lower than its yield strength (235MPa), effectively preventing fracture failure.

[0028] According to the appendix Figure 2-3 As shown, the support body 1 is further configured as U-shaped, and there are two support plates 2, which are integrally formed with the two top ends of the support body 1.

[0029] The first reinforcing rib 4 and the second reinforcing rib 5 are respectively embedded in the two vertical parts of the U-shaped support body 1.

[0030] The outer edge of the bracket body 1 is provided with a edging 6.

[0031] The main body of the bracket 1 has a kettle mounting hole 7 that runs through the front and back.

[0032] The support plate 2 has a through bracket mounting hole 8.

[0033] According to the appendix Figure 4 As shown, further modal analysis reveals that the first natural frequency of the integrated kettle assembly is 12.29 Hz, which is an improvement over the previous mode.

[0034] Strength analysis: The optimized integrated kettle bracket has the same loading conditions as before, with only the addition of support profile 3. The calculated maximum Mises stress is 254.7 MPa, which significantly reduces the stress at this point.

[0035] According to the appendix Figure 5 As shown, further, the result is less than the material yield strength of 420 MPa; the material of the support profile 3 is Q235 steel, and the calculated maximum Mises stress is 129.46 MPa.

[0036] According to the appendix Figure 6 As shown, further, the yield strength of the material is less than 235 MPa, and the overall structure successfully passed the durability road test, indicating that the support profile 3 can effectively improve the load-bearing capacity of the support.

[0037] The main body 1 of the support frame has a U-shaped bend structure, and the angle between it and the support plate 2 is the original stress concentration area. The added support profile 3 forms a triangular stable structure with the main body 1 and the support plate 2, transferring the concentrated stress at the bend to the support profile 3, thereby reducing local stress by increasing the force transmission path.

[0038] The first reinforcing rib 4 and the second reinforcing rib 5 are embedded in the vertical part of the U-shaped bracket body 1, which increases the local cross-sectional moment of inertia and improves the bracket's resistance to deformation. The outer edge edging 6 further constrains the edge warping of the bracket body 1, and together with the triangular structure of the supporting profile 3, improves the overall rigidity of the system.

[0039] The kettle is fixed to the main body of the bracket 1 through the kettle mounting hole 7. Its gravity and road vibration load are sequentially transferred from the main body of the bracket to the support profile 3 and the support plate 2, and finally to the frame through the bracket mounting hole 8. The synergistic effect of the support profile 3, the first reinforcing rib 4, and the second reinforcing rib 5 ensures that the load is evenly distributed during the transfer process, avoiding local overload.
