Description

Technical Field

[0001] This utility model relates to the field of automotive bushing assembly technology, and in particular to a bushing bracket. Background Technology

[0002] Currently, automotive control arms are becoming increasingly diverse, with multi-link variants being used more and more frequently, leading to a corresponding increase in the number of bushings. Within the limited space around the wheels, the number of bushing mounting points is also increasing, and their installation positions are increasingly offset from the vehicle's frame. Furthermore, there are more and more cases where bushing mounting brackets need to be directly extended from the frame without raising the subframe. The bushing bracket structure is a key structural element affecting bushing performance and plays a crucial role in the increasing complexity of control arms.

[0003] In the design phase, existing control arm supports typically have their hard points positioned directly below the vehicle frame to better align with it. This allows for better spatial positioning during the design process, resulting in superior rigidity and strength.

[0004] However, in some special structures, such as steering structures with large wheel angles, the sweep radius of the wheel center is larger, which causes the gear to interfere with the existing bushing installation position. However, if the bushing and the beam are offset in the y-axis direction, the rigidity of the traditional bushing bracket is difficult to meet the installation requirements of the control arm. Utility Model Content

[0005] The main purpose of this invention is to propose a bushing bracket that addresses how to improve the rigidity of the bushing bracket to meet the installation requirements of the control arm when the bushing and the main beam are misaligned in the y-axis direction.

[0008] In one embodiment, the outer sheet metal includes a first outer sheet metal part, a second outer sheet metal part, and a third outer sheet metal part connected in sequence. The first outer sheet metal part is used to connect to the side of the beam away from the first inner sheet metal part.

[0024] Currently, automotive control arms are becoming increasingly diverse, with multi-link variants being used more and more frequently, leading to a corresponding increase in the number of bushings. Within the limited space around the wheels, the number of bushing mounting points is also increasing, and their installation positions are increasingly offset from the vehicle's frame. Furthermore, there are more and more cases where bushing mounting brackets need to be directly extended from the frame without raising the subframe. The bushing bracket structure is a key structural element affecting bushing performance and plays a crucial role in the increasing complexity of control arms.

[0025] In the design phase, existing control arm supports typically have their hard points positioned directly below the vehicle frame to better align with it. This allows for better spatial positioning during the design process, resulting in superior rigidity and strength.

[0026] However, in some special structures, such as steering structures with large wheel angles, the sweep radius of the wheel center is larger, which causes the gear to interfere with the existing bushing installation position. However, if the bushing and the beam are offset in the y-axis direction, the rigidity of the traditional bushing bracket is difficult to meet the installation requirements of the control arm.

[0027] The inventors discovered that in traditional bushing brackets, the outer sheet metal is connected to the main beam, with the outer sheet metal being U-shaped and the inner sheet metal located inside it. The bushing structure is situated between the outer and inner sheet metals, with its upper end connected to the inner sheet metal and its lower end connected to the outer sheet metal. If the bushing and main beam shift in the y-axis direction, the outer sheet metal will tilt to accommodate this shift, reducing the stiffness provided to the control arm in the z-axis direction. Furthermore, the inner sheet metal is located inside the outer sheet metal, with its sidewalls spot-welded to it. The contact area between the inner and outer sheet metal is directly proportional to the thickness of the inner sheet metal. This design results in a small contact area between the inner and outer sheet metal, leading to low spot weld strength and making it difficult to provide the control arm with the required z-axis stiffness for its installation.

[0028] This utility model proposes a bushing bracket, which aims to solve the problem of how to improve the rigidity of the bushing bracket to meet the installation requirements of the control arm when the bushing and the main beam are misaligned in the y-axis direction.

[0029] Please see Figures 1 to 3 In one embodiment of this utility model, the bushing bracket 100 includes a sheet metal assembly 1, a mounting bracket 2, a reinforcing rib 3, and a bushing assembly 4. The sheet metal assembly 1 includes an outer sheet metal 11 and an inner sheet metal 12. One end of the outer sheet metal 11 is used for fixed connection with the main beam 200, and one end of the inner sheet metal 12 is used for fixed connection with the main beam 200. The other ends of the outer sheet metal 11 and the other ends of the inner sheet metal 12 are stacked and connected to each other to form a mounting platform 5. The mounting bracket 2 is connected to the outer sheet metal 11 and is located on the outer sheet metal 11 away from the inner sheet metal 12. 2. One side; the reinforcing rib 3 includes a first connecting part 31, a second connecting part 32, and a third connecting part 33 for connecting the first connecting part 31 and the second connecting part 32. The first connecting part 31 extends in a direction perpendicular to the mounting platform 5, and the second connecting part 32 extends in a direction parallel to the mounting platform 5. The first connecting part 31 is connected to the end of the inner sheet metal 12 away from the mounting platform 5, and the second connecting part 32 is connected to the end of the inner sheet metal 12 close to the mounting platform 5. One end of the bushing assembly 4 is connected to the mounting platform 5, and the other end of the bushing assembly 4 is connected to the mounting bracket 2.

[0030] The technical solution of this utility model uses an outer sheet metal 11 and an inner sheet metal 12, both connected at one end to the main beam 200. The outer sheet metal 11 and the inner sheet metal 12, away from the main beam 200, are stacked to form a mounting platform 5. This allows the upper end of the bushing assembly 4 to be connected to both the inner sheet metal 12 and the outer sheet metal 11. Compared to a system where the upper end of the bushing assembly 4 is only connected to the outer sheet metal 11, this embodiment provides better rigidity in the x-axis and y-axis directions for the control arm mounted on the bushing assembly 4. This means the bushing assembly 4 is less prone to movement in the x-axis and y-axis directions. The stacking of the outer sheet metal 11 and the inner sheet metal 12 significantly increases its rigidity in the x-axis and y-axis directions compared to a single outer sheet metal 11. The xoy plane formed by the x-axis and y-axis is parallel to the ground, and the z-axis is perpendicular to the xoy plane. By setting the mounting bracket 2, the actual... The lower end of the bushing assembly 4 is fixed. By setting a reinforcing rib 3, and connecting the first connecting part 31 of the reinforcing rib 3 to the end of the inner sheet metal 12 away from the mounting platform 5, and connecting the second connecting part 32 to the end of the inner sheet metal 12 near the mounting platform 5, the first connecting part 31 extends along the z-axis direction, the second connecting part 32 extends along the y-axis direction, and the first connecting part 31 and the second connecting part 32 are connected by the third connecting part 33, so that the force acting on the mounting platform 5 in the z-axis direction can be effectively transmitted to the main beam 200, thereby improving the strength of the structure and making the mounting platform 5 less likely to move in the z-axis direction. Compared with the inner sheet metal 12 without the reinforcing rib 3, the technical solution of this embodiment increases the stiffness of the inner sheet metal 12 with the reinforcing rib 3 in the z-axis direction by adding the above-mentioned reinforcing rib 3, so that the bushing bracket 100 can provide better z-axis stiffness for the control arm set on the bushing assembly 4 to meet the installation requirements of the control arm. Furthermore, the bushing bracket 100 in this embodiment abandons the traditional surrounding structure. It forms a mounting platform 5 by pressing the inner sheet metal 12 and the outer sheet metal 11 together at their ends furthest from the main beam 200. The size of the mounting platform 5 can be selected according to requirements, thereby compensating for the difference in y-axis distance between the bushing and the main beam 200. Practical application has shown that the bushing bracket 100 of this embodiment uses less material and has a higher material utilization rate compared to a traditional bracket with the same rigidity. It should be noted that the control arm is mounted on the bushing body 41, which is an existing bushing, and the control arm is mounted on the bushing body 41 using the existing mounting method. It should also be noted that the y-axis direction is... Figure 1 The left and right directions are shown, and the z-axis direction is... Figure 1 As shown in the vertical direction, the x-axis is perpendicular to the y-axis and z-axis.

[0031] Please see Figure 1In one embodiment, the inner sheet metal 12 includes a first inner sheet metal part 121 and a second inner sheet metal part 122 that are connected to each other. The first inner sheet metal part 121 is connected to the main beam 200. The second inner sheet metal part 122 is stacked with the outer sheet metal 11 at the end away from the main beam 200 and connected to each other to form a mounting platform 5. The first connecting part 31 is connected to the first inner sheet metal part 121, the second connecting part 32 is connected to the second inner sheet metal part 122, and the third connecting part 33 is located at the connection between the first inner sheet metal part 121 and the second inner sheet metal part 122, and both the first inner sheet metal part 121 and the second inner sheet metal part 122 are connected to the third connecting part 33. The first connecting part 31 is connected to the first inner sheet metal part 121, the second connecting part 32 is connected to the second inner sheet metal part 122, and the first connecting part 31 and the second connecting part 32 are connected by the third connecting part 33. This makes the mounting platform 5 less prone to movement in the z-axis direction, improving its rigidity and better meeting the installation requirements of the control arm. Furthermore, the third connecting part 33 is also located at the connection between the first inner sheet metal part 121 and the second inner sheet metal part 122, both of which are connected to the third connecting part 33. This further prevents the mounting platform 5 from moving in the z-axis direction, thus better meeting the installation requirements of the control arm. It should be noted that the first inner sheet metal part 121 is welded to the main beam 200.

[0032] Please see Figure 1 In one embodiment, the outer sheet metal 11 includes a first outer sheet metal part 111, a second outer sheet metal part 112, and a third outer sheet metal part 113 connected in sequence. The first outer sheet metal part 111 is used to connect to the side of the main beam 200 away from the first inner sheet metal part 121. The third outer sheet metal part 113 is stacked and connected to the second inner sheet metal part 122 to form a mounting platform 5. The mounting bracket 2 is connected to the mounting platform 5. The first outer sheet metal part 111 is connected to the main beam 200, one end of the second outer sheet metal part 112 is connected to the first outer sheet metal part 111, and the other end of the second outer sheet metal part 112 is connected to the third outer sheet metal part 113. The third outer sheet metal part 113 is stacked and connected to the second inner sheet metal part 122. The resulting mounting platform 5 has better rigidity in the x-axis and y-axis directions compared to either the outer sheet metal 11 or the inner sheet metal 12, thus better meeting the installation requirements of the control arm. It should be noted that, with the thickness of the inner sheet metal 12 and the outer sheet metal 11 remaining unchanged, the strength and rigidity of the bushing bracket 100 in the x-axis and y-axis directions can be adjusted by adjusting the size of the mounting platform 5, and the strength and rigidity of the bushing bracket 100 in the y-axis and z-axis directions can be adjusted by changing the size of the reinforcing rib 3, thereby meeting different installation requirements of the control arm.

[0033] Please see Figures 1 to 3In one embodiment, the third outer sheet metal portion 113 is attached to and fixedly connected with the second inner sheet metal portion 122. By attaching the third outer sheet metal portion 113 to the second inner sheet metal portion 122, the contact area between the third outer sheet metal portion 113 and the second inner sheet metal portion 122 is effectively increased, thereby effectively improving the rigidity of the mounting platform 5 in the x-axis and y-axis directions, and thus better meeting the installation requirements of the control arm. It should be noted that the third outer sheet metal portion 113 and the second inner sheet metal portion 122 are pressed together using existing processes to ensure that the fixing strength of the outer sheet metal 11 and the inner sheet metal 12 meets the requirements. It should also be noted that spot welding can also be used to achieve the fixed connection between the third outer sheet metal portion 113 and the second inner sheet metal portion 122, but spot welding has requirements on the sheet metal thickness; if it is too thick, spot welding is not possible, and if it is too thin, the strength requirements cannot be met.

[0034] Please see Figure 1 In one embodiment, the end of the second outer sheet metal portion 112 away from the first outer sheet metal portion 111 is obliquely cut towards the bushing, and the second outer sheet metal portion 112 is spaced apart from the inner sheet metal portion 12. The end of the second outer sheet metal portion 112 away from the first outer sheet metal portion 111 is inclined to the right, which allows the second outer sheet metal portion 112 to effectively avoid the wheel 300, and also achieves the connection between the first outer sheet metal portion 111 and the third outer sheet metal portion 113 at a lower cost.

[0035] Please see Figure 1 and Figure 2In one embodiment, the mounting bracket 2 includes a first mounting part 21, a second mounting part 22, and a third mounting part 23 connected in sequence. The first mounting part 21 is connected to the mounting platform 5, and the third mounting part 23 and the mounting platform 5 are spaced apart in a direction perpendicular to the mounting platform 5 to form a mounting space 24. The bushing assembly 4 includes a bushing body 41 and a connector 42 connected to each other. The bushing body 41 is located in the mounting space 24, one end of the connector 42 is connected to the mounting platform 5, and the other end of the connector 42 is connected to the third mounting part 23. The third mounting part 23 is located below the third outer sheet metal part 113 and is spaced apart from the third outer sheet metal part 113 to form a mounting space 24 for accommodating the bushing body 41. The first end of the connector 42 is connected to the mounting platform 5, and the other end of the connector 42 is connected to the third mounting part 23. The connector 42 and the mounting platform 5 can be welded together or detachably connected. Alternatively, the connector 42 can pass through the mounting platform 5 and be threadedly connected to it with a nut, or it can pass through the mounting platform 5 and be restricted from leaving the mounting platform 5 by a positioning pin. The connection relationship between the connector 42 and the third mounting part 23 is similar and will not be described further. It should be noted that the mounting bracket 2 can be a casting or a stamped part with a diameter of 4mm or more. The connector 42 can be a connecting shaft passing through the bushing body 41 or a connecting block located on both sides of the bushing body 41; there are no restrictions on its use.

[0036] In one embodiment, the bushing body 41 is used to connect to the control arm; the control arm is provided with a through hole for accommodating the bushing body 41.

[0037] In one embodiment, the first connecting part 31 is detachably connected to the mounting platform 5. The first connecting part 31 can be detachably connected to the mounting platform 5 by bolts and nuts. Specifically, the bolt passes through the first connecting part 31 and the mounting platform 5 and is threadedly connected to the nut; alternatively, both the first connecting part 31 and the mounting platform 5 are provided with threaded holes, and the bolt is threadedly connected to the threaded holes of the first connecting part 31 and the mounting platform 5.

[0038] Please see Figure 1 In one embodiment, the thickness of the outer sheet metal 11 is h1, wherein 1.5mm≤h1≤2.5mm; wherein the outer radius thickness can be 2.4mm. If the sheet metal thickness is too thick, the spot welding strength will be insufficient, and if the sheet metal is too thin, the structural rigidity will be insufficient. Controlling the thickness of the outer sheet metal 11 between 1.5mm and 2.5mm can meet both the spot welding requirements and ensure that its rigidity meets the requirements.

[0039] Please see Figure 1In one embodiment, the thickness of the inner sheet metal 12 is h2, where 1.5mm ≤ h2 ≤ 2.5mm. The outer radius thickness can be 2.4mm. If the sheet metal thickness is too thick, the spot welding strength will be insufficient; if the sheet metal is too thin, the structural rigidity will be insufficient. Controlling the thickness of the inner sheet metal 12 between 1.5mm and 2.5mm can meet both the spot welding requirements and the rigidity requirements.

[0040] In one embodiment, the reinforcing rib 3 is a triangular reinforcing rib 3. The reinforcing rib 3 is a triangular reinforcing rib 3 or an approximately triangular reinforcing rib 3, which utilizes the stable structural properties of a triangle to improve the structural strength of the bushing support 100.

[0041] In one embodiment, there are multiple reinforcing ribs 3, which are spaced apart. By providing multiple reinforcing ribs 3, the structural strength of the bushing bracket 100 is further improved. The number and size of the reinforcing ribs 3, as well as the size of the mounting platform 5, can be adjusted to meet the strength and rigidity requirements of the control arm during installation, thus improving the adaptability of the control arm to different installation needs.

[0042] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
