Technical Field
[0001] This utility model relates to the field of vehicle parts, specifically to a functional bracket for the integrated installation of a power mount assembly and an independent suspension assembly. Background Technology
[0002] Currently in the automotive industry, when a non-load-bearing body is equipped with a front-drive powertrain and independent suspension, a dedicated suspension bracket is designed separately for the front-drive powertrain, and a dedicated mounting bracket is designed separately for the top of the independent suspension. This design involves two large brackets, which need to be designed and verified separately, resulting in a large workload and increased design cycle and cost. At the same time, it occupies more space in the front engine compartment during assembly, which is not conducive to the compact layout design of various components in the front engine compartment.
[0003] Therefore, to solve the above problems, a functional bracket is needed for the integrated installation of the power mount assembly and the independent suspension assembly, which can integrate the two brackets, reduce development cycle and cost, and improve the compactness of the arrangement of various components in the front engine compartment. Utility Model Content
[0004] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a functional bracket for the integrated installation of the power suspension assembly and the independent suspension assembly, which can integrate the two brackets, reduce the development cycle and cost, and improve the compactness of the arrangement of various components in the front engine compartment.
[0005] This utility model discloses a functional bracket for the integrated installation of a power mount assembly and an independent suspension assembly. It includes a bracket body mounted on the vehicle frame, more specifically, the bracket body is mounted on the longitudinal beam of the vehicle frame. The bracket body has an independent suspension mounting area and a power mount mounting area. This allows for the integration of two brackets, reducing development cycle and cost. The proximity of the independent suspension mounting area and the power mount mounting area improves the compactness of the layout of various components in the front engine compartment. It provides more space for other components in the front engine compartment, which is beneficial for engine compartment heat dissipation, streamlined engine compartment design, and aesthetic appeal. The power mount... The mounting area is located near the inner side of the vehicle, while the independent suspension mounting area is located near the outer side of the vehicle. This design simplifies the structure, improves assembly convenience, and enhances the assembly efficiency of corresponding components. The near-back-to-back arrangement of the two mounting areas results in higher integration of the bracket body and superior structural compactness. The integrated bracket exhibits higher modal strength and overall NVH performance compared to traditional brackets, thus improving the overall vehicle's NVH. Furthermore, it reduces the design cycle, verification cycle, and the number of molds required, resulting in lower design, development, and management costs. This design approach reduces costs and increases efficiency, while also possessing a degree of versatility, making it suitable for use in vehicle non-load-bearing body structures.
[0006] Furthermore, the bracket body has an assembly end, which is a strip extending longitudinally. The bracket body is fixed to the longitudinal beam via the assembly end, and the assembly points of the assembly end on the longitudinal beam are a plurality of points arranged at intervals in the longitudinal direction. The cross section of the assembly end is an inverted "L" shape, with the horizontal side of the "L" shape connected to the top surface of the longitudinal beam and the vertical side of the "L" shape connected to the side of the longitudinal beam near the independent suspension. The inverted "L" shape of the assembly end can improve the fixing strength of the bracket body on the longitudinal beam, which is conducive to ensuring the reliable assembly of the suspension assembly and the independent suspension assembly on the vehicle frame, and the force transmission is more stable, which can prevent vibration and abnormal noise of the components.
[0007] Furthermore, the independent suspension includes a shock absorber. The bracket body has a shock absorber mounting position protruding upwards from bottom to top. This shock absorber mounting position forms a cavity-like structure, which substantially limits the top of the shock absorber to the bottom of the shock absorber mounting position. The top of the shock absorber mounting position forms a shock absorber assembly part, and the top of the shock absorber is fixed to the shock absorber assembly part. The shock absorber mounting position has a limiting part for limiting the top of the shock absorber. An assembly hole is formed on the shock absorber assembly part, and the assembly hole forms the limiting part. The top of the shock absorber has a limiting end that extends into the assembly hole, and the top of the shock absorber also abuts against the bottom surface of the cavity-like structure formed by the shock absorber mounting position. At the same time, the top of the shock absorber is fixed to the shock absorber assembly part by bolts. There are three bolts evenly distributed around the top of the shock absorber, which makes the force transmission more reliable, prevents the shock absorber from vibrating and deflecting, and improves the assembly stability.
[0008] Furthermore, the independent suspension also includes an upper wishbone, and the bracket body further has a front clamping plate and a rear clamping plate protruding upwards from bottom to top; the front clamping plate is located on the longitudinal front side of the shock absorber mounting position, and the front clamping plate and the longitudinal front end face of the shock absorber mounting position form an upper wishbone mounting position I that limits the upper wishbone front arm; the rear clamping plate is located on the longitudinal rear side of the shock absorber mounting position, and the rear clamping plate and the longitudinal rear end face of the shock absorber mounting position form an upper wishbone mounting position II that limits the upper wishbone rear arm. More specifically, the upper wishbone front arm is hinged to the upper wishbone mounting position I via hinge shaft I, and the upper wishbone rear arm is hinged to the upper wishbone mounting position II via hinge shaft II; the central axis of hinge shaft I coincides with the central axis of hinge shaft II, and the coincident central axis is located at the top of the shock absorber assembly. That is, the shock absorber is located between the fork arm and the rear arm, and the fork arm has the degree of freedom to swing around the hinge axis I. The fork arm is directly assembled using the side wall of the shock absorber mounting position, making the structure more compact and reliable.
[0009] Furthermore, the bracket body has upward-protruding power mount mounting posts, on which the power mount frame is assembled. There are three power mount mounting posts, arranged in a triangle on the bracket body. The triangle has sides parallel to the longitudinal direction and angles facing outwards from the vehicle. This allows for more accurate assembly and positioning of the power mount and provides superior structural strength. In this design, the three power mount mounting posts are arranged longitudinally close to the rear plate, while the shock absorber mounting position is arranged longitudinally close to the front plate. This improves structural compactness, modal characteristics, and strength compared to traditional brackets, thereby enhancing the overall vehicle NVH (noise, vibration, and harshness).
[0010] Furthermore, the bracket body also has reinforcing ribs. In this solution, the reinforcing ribs are distributed at the shock absorber mounting position, upper wishbone mounting position I, upper wishbone mounting position II, power suspension mounting column, between the shock absorber mounting position and upper wishbone mounting position I, between the shock absorber mounting position and upper wishbone mounting position II, and between the power suspension mounting column and upper wishbone mounting position II, to ensure the structural strength of the bracket body and improve the NVH of the whole vehicle.
[0011] The beneficial effects of this utility model are as follows: This utility model discloses a functional bracket for the integrated installation of a power mount assembly and an independent suspension assembly. Through a bracket body mounted on the vehicle frame, the two brackets can be integrated, reducing development cycle and cost. More specifically, the bracket body is mounted on the longitudinal beam of the vehicle frame, and the bracket body has an independent suspension mounting area and a power mount mounting area. The proximity of the independent suspension mounting area and the power mount mounting area improves the compactness of the arrangement of various components in the front engine compartment; it provides more space for other components in the front engine compartment, which is beneficial for engine compartment heat dissipation, engine compartment flow, and engine compartment aesthetics. The design features a power suspension mounting area close to the inner side of the vehicle and an independent suspension mounting area close to the outer side, resulting in a simpler structure, better assembly convenience, and improved assembly efficiency for corresponding components. The near-back-to-back arrangement of the two components enhances the integration of the bracket body and improves structural compactness. The integrated bracket exhibits higher modal strength and overall NVH performance compared to traditional brackets. Furthermore, it reduces design and verification cycles and the number of molds required, resulting in lower design, development, and management costs. This design approach offers cost reduction and efficiency improvement, while also possessing a degree of versatility, making it suitable for use in vehicle body structures without load-bearing capacity.

[0020] In this embodiment, the bracket body has an assembly end 1, which is a strip extending longitudinally. The bracket body is fixed on the longitudinal beam via the assembly end 1. The assembly points of the assembly end 1 on the longitudinal beam are a plurality of points arranged at intervals in the longitudinal direction. The cross section of the assembly end 1 is an inverted "L" shape. The horizontal side of the "L" shape is connected to the top surface of the longitudinal beam, and the vertical side of the "L" shape is connected to the side of the longitudinal beam near the independent suspension. The inverted "L" shape of the assembly end 1 can improve the fixing strength of the bracket body on the longitudinal beam, which is conducive to ensuring the reliable assembly of the suspension assembly and the independent suspension assembly on the vehicle frame, and the force transmission is more stable, which can prevent vibration and abnormal noise of the components.
[0021] In this embodiment, the independent suspension includes a shock absorber. The bracket body has a shock absorber mounting position 2 protruding upwards from bottom to top. The shock absorber mounting position forms a cavity-like structure, so that the top of the shock absorber is approximately limited at the bottom of the shock absorber mounting position 2. The top of the shock absorber mounting position 2 forms a shock absorber assembly part, and the top of the shock absorber is fixed to the shock absorber assembly part. The shock absorber mounting position 2 has a limiting part for limiting the top of the shock absorber. An assembly hole is formed on the shock absorber assembly part, and the assembly hole forms a limiting part. The top of the shock absorber has a limiting end that extends into the assembly hole, and the top of the shock absorber also abuts against the bottom surface of the cavity-like structure formed by the shock absorber mounting position. At the same time, the top of the shock absorber is fixed to the shock absorber assembly part by bolts. There are three bolts evenly distributed around the top of the shock absorber, which makes the force transmission more reliable, prevents the vibration deflection of the shock absorber, and improves the assembly stability.
[0022] In this embodiment, the independent suspension also includes an upper wishbone, and the bracket body further has a front clamping plate 3 and a rear clamping plate 4 protruding upwards from bottom to top; the front clamping plate 3 is located on the longitudinal front side of the shock absorber mounting position 2, and the front clamping plate 3 and the longitudinal front end face of the shock absorber mounting position 2 form an upper wishbone mounting position I that limits the front arm of the upper wishbone; the rear clamping plate 4 is located on the longitudinal rear side of the shock absorber mounting position 2, and the rear clamping plate 4 and the longitudinal rear end face of the shock absorber mounting position 2 form an upper wishbone mounting position II that limits the rear arm of the upper wishbone. The front and rear correspond... Figure 1 The independent suspension is positioned forward, while the power suspension is positioned rearward. More specifically, the upper wishbone front arm is hinged to the upper wishbone mounting position I via hinge shaft I, and the upper wishbone rear arm is hinged to the upper wishbone mounting position II via hinge shaft II. The central axis of hinge shaft I coincides with the central axis of hinge shaft II, and the coincident central axis is located at the top of the shock absorber assembly. That is, the shock absorber is located between the front and rear arms of the wishbone, and the wishbone has the freedom to swing around hinge shaft I. The wishbone is directly assembled using the side wall of the shock absorber mounting position 2, resulting in a more compact and reliable structure.
[0023] In this embodiment, the bracket body has three power suspension mounting columns 5 protruding upwards from bottom to top. The power suspension frame is assembled on the power suspension mounting columns 5. The three power suspension mounting columns 5 are distributed in a triangle on the bracket body. The triangle has sides parallel to the longitudinal direction and angles facing outwards from the vehicle. The height of the power suspension mounting columns arranged laterally closer to the inner side is higher than that of the two power suspension mounting columns arranged laterally closer to the outer side, so that the frame of the power suspension is assembled more stably on the bracket body in a stepped pedestal structure. Furthermore, the assembly and positioning of the power suspension is more accurate, and the structural strength is better. In this solution, the three power suspension mounting columns 5 are arranged longitudinally closer to the rear clamp 4, and the shock absorber mounting position 2 is arranged longitudinally closer to the front clamp 3. This improves the structural compactness, modal strength, and overall strength compared to traditional brackets, thereby improving the NVH of the entire vehicle.
