Description

Technical Field

[0001] This application relates to vehicle component technology, and more particularly to a suspension mounting bracket and a vehicle. Background Technology

[0002] The vehicle's body longitudinal beams are connected to the suspension system via a suspension mounting structure. This mounting structure must withstand the vibrations and impacts generated by the engine during operation, as well as static loads. Therefore, the structural strength and dynamic characteristics of the suspension mounting structure have a significant impact on the overall vehicle performance.

[0003] In related technologies, the mounting structure is generally made of aluminum alloy. The mounting structure is bolted to the longitudinal beam of the vehicle body, and the mounting system is then connected to the mounting structure to achieve the connection between the mounting system and the longitudinal beam of the vehicle body.

[0004] However, while aluminum alloy materials can ensure the connection strength between the suspension system and the body longitudinal beams, they also significantly increase material and overall manufacturing costs, increase the complexity of the body structure assembly process, and seriously affect the vehicle assembly schedule. Utility Model Content

[0005] This application provides a suspension mounting bracket and a vehicle to solve the technical problem of high cost when using aluminum alloy materials for suspension mounting brackets in related technologies.

[0006] On one hand, this application provides a suspension mounting bracket, including:

[0007] The first mounting component is used to connect to the longitudinal beams of the vehicle body;

[0008] The second mounting component is located on the side of the first mounting component away from the longitudinal beam of the vehicle body, and the second mounting component has a mounting portion along the side away from the first mounting component.

[0009] A reinforcing member is provided on the side of the mounting portion facing the first mounting member;

[0010] The fastener has one end connected to the reinforcing member and the other end connected to the first mounting member;

[0011] A connector, which passes through the mounting portion into the fixing member, is configured to connect the suspension assembly and the fixing member.

[0012] In some possible implementations, the first mounting member includes a support portion and two bent portions respectively disposed at opposite ends of the support portion, the two bent portions being located on the same side of the support portion, the bent portions being used to connect with the vehicle body longitudinal beam, and the support portion being connected with the fastener.

[0013] In some possible implementations, the projection of the mounting portion onto the first mounting member is located in the support portion; or, the projection of the mounting portion onto the first mounting member coincides with the support portion.

[0014] In some possible implementations, the second mounting member includes a back plate and mounting plates respectively disposed at opposite ends of the mounting portion. The mounting plates are connected to at least one of the first mounting member and the vehicle body longitudinal beam. The back plate is located on the same side of the mounting plates and the mounting portion, and the back plate is connected to both the mounting plates and the mounting portion.

[0015] The back panel is configured to, together with the mounting part, the mounting plate and the vehicle body longitudinal beam, form a closed or semi-closed box structure.

[0016] In some possible implementations, the back plate extends in a direction away from the mounting portion to form a first connecting portion, which is used to connect with the vehicle body longitudinal beam.

[0017] In some possible implementations, the mounting plate is bent in the direction toward the mounting portion to form a second connecting portion, the second connecting portion on one of the two mounting plates is used to connect with the longitudinal beam elevation of the vehicle body longitudinal beam, and the second connecting portion on the other of the two mounting plates is used to connect with the wheel arch reinforcement plate.

[0018] In some possible implementations, the mounting portion is bent along the side opposite to the back plate to form a third connecting portion, which is used to connect with the wheel cover reinforcement plate.

The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] The terms "first," "second," "third," "fourth," etc., used in this application's specification and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0044] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0045] As described in the background section, current suspension mounting structures are generally made of aluminum alloy. The suspension mounting structure is bolted to the vehicle body longitudinal beam, and the suspension system is then connected to the suspension mounting structure to achieve the connection between the suspension system and the vehicle body longitudinal beam.

[0046] However, while aluminum alloys can ensure the connection strength between the suspension system and the vehicle's longitudinal beams, they also significantly increase material and overall manufacturing costs, increase the complexity of the vehicle body assembly process, and severely impact the overall vehicle assembly schedule. Therefore, it is necessary to develop a suspension mounting structure that is structurally sound, lightweight, and possesses enhanced strength, while minimizing operating costs to meet performance requirements.

[0047] Based on the above description, one or more embodiments of this application provide a suspension mounting bracket and a vehicle, wherein one end of the fixing member is connected to the reinforcing member and the other end is connected to the first mounting member. The reinforcing member is disposed on the side of the mounting part facing the first mounting member. Thus, the reinforcing member can form a force transmission transition between the second mounting member and the fixing member. The vibration and impact load from the suspension system is first diffused and transferred through the reinforcing member before being transmitted to the second mounting member, which optimizes the load distribution path and helps to improve the structural strength and reliability of the entire suspension mounting bracket.

[0048] The following description, in conjunction with the accompanying drawings, illustrates the solutions of the embodiments of this application.

[0049] like Figure 1 and Figure 2 As shown in the figure, this application provides a suspension mounting bracket, including a first mounting member 100, a second mounting member 200, a reinforcing member 300, a fixing member 400, and a connecting member 500.

[0050] The first mounting member 100 is used to connect with the vehicle body longitudinal beam 600; the second mounting member 200 is provided on the side of the first mounting member 100 away from the vehicle body longitudinal beam 600, and the second mounting member 200 has a mounting portion 210 along the side away from the first mounting member 100; the reinforcing member 300 is provided on the side of the mounting portion 210 facing the first mounting member 100; one end of the fixing member 400 is connected to the reinforcing member 300, and the other end is connected to the first mounting member 100; the connecting member 500 passes through the mounting portion 210 and is inserted into the fixing member 400, and the connecting member 500 is configured to connect the suspension assembly 700 and the fixing member 400 so that the suspension assembly 700 and the vehicle body longitudinal beam 600 are connected.

[0051] As can be seen from the above description, in the suspension mounting bracket of this application embodiment, a reinforcing member 300 is provided on the side of the mounting part 210 facing the first mounting member 100, and the fixing member 400 is connected to the reinforcing member 300 and the first mounting member 100 respectively. Thus, the reinforcing member 300 can form a force transmission transition between the second mounting member 200 and the fixing member 400. The vibration and impact load from the suspension system is first diffused and transitioned through the reinforcing member 300 before being transmitted to the second mounting member 200. This optimizes the load distribution path and improves the structural strength and dynamic stiffness of the entire suspension mounting bracket while meeting the fatigue resistance requirements of the suspension mounting bracket.

[0052] Furthermore, the reinforcing member 300 provided on the side of the mounting part 210 facing the first mounting member 100 can serve as a transfer component of the fixing member 400, avoiding the welding heat deformation problem that is prone to occur when the fixing member 400 is directly welded to the mounting part 210 in related technologies. This helps to ensure the installation flatness and perpendicularity of the mounting part 210 and the suspension assembly 700, and ensures the assembly accuracy of the suspension mounting bracket.

[0053] In this embodiment, the suspension mounting bracket connects the vehicle's longitudinal beam 600 and the suspension assembly 700. The connector 500 of the suspension mounting bracket connects the suspension assembly 700 and the fixing member 400. The first mounting member 100 is connected to the longitudinal beam 600, thus forming a connection between the longitudinal beam 600 and the suspension assembly 700. The longitudinal beam 600 and the suspension assembly 700 can refer to the vehicle body component structures in related technologies, and are not absolutely limited in this embodiment.

[0054] It should be noted that the directional terms such as "bottom" and "upper" mentioned in the embodiments of this application are used to describe the position of the suspension mounting bracket after it is assembled on the vehicle body longitudinal beam 600. Along the height direction of the vehicle, the suspension assembly 700 is located on the upper part of the suspension mounting bracket, and the suspension mounting bracket is located on the upper part of the vehicle body longitudinal beam 600. This will not be repeated in the embodiments of this application.

[0055] In some embodiments, the first mounting member 100, the second mounting member 200, and the reinforcing member 300 are all stamped sheet metal structures. The first mounting member 100, the second mounting member 200, and the reinforcing member 300 are welded together to replace the integrated die-cast aluminum alloy bracket in the related technology. Thus, while ensuring the structural strength of the suspension mounting bracket, the material and manufacturing costs of individual parts can be reduced. The overall strength is improved through structural design rather than relying on high-performance, high-cost materials themselves, thereby achieving higher cost efficiency.

[0056] For example, such as Figure 5As shown, the first mounting member 100 includes a support portion 110 and two bent portions 120 provided at opposite ends of the support portion 110, the two bent portions 120 are located on the same side of the support portion 110, the bent portions 120 are configured to be connected with a vehicle body side rail 600, and the support portion 110 is connected with a fixing member 400.

[0057] The above-mentioned first mounting member 100 forms a folded plate structure with an approximately "Ω"-shaped cross-section through the support portion 110 and the two bent portions 120. The "Ω"-shaped folded plate structure itself has relatively high bending and torsional stiffness. After the two bent portions 120 are welded to the top surface of the vehicle body side rail 600, the bent portions 120, the support portion 110 and the top surface of the vehicle body side rail 600 together enclose to form a semi-closed box-type structure. This design can resist vibration and impact loads from all directions from the mount assembly 700, and improve the local stiffness and connection stability of the mount mounting bracket and the vehicle body side rail 600.

[0058] In addition, the vibration and impact load of the mount assembly 700 is transmitted to the support portion 110 through the fixing member 400, and then dispersed and transitioned to the large-area vehicle body side rail 600 through the bent portions 120 at both ends, thereby avoiding stress concentration on the vehicle body side rail 600, which is beneficial to improving the safety and durability of the entire vehicle body structure.

[0059] Further, the projection of the mounting portion 210 on the first mounting member 100 is located in the support portion 110; or, the projection of the mounting portion 210 on the first mounting member 100 coincides with the support portion 110.

[0060] As an example Figure 4 and Figure 5 As shown, the projection of the mounting portion 210 on the first mounting member 100 refers to the projection of the main body portion of the mounting portion 210 that is not bent downward on the first mounting member 100. The cross-sectional dimension of the mounting portion 210 is slightly smaller than the cross-sectional dimension of the support portion 110, and the projection of the mounting portion 210 on the first mounting member 100 is located in the support portion 110. When the cross-sectional dimension of the mounting portion 210 is the same as the cross-sectional dimension of the support portion 110, the projection of the mounting portion 210 on the first mounting member 100 coincides with the support portion 110. In this case, flexible adjustment can be made according to the bending angle between the mounting portion 210 and the mounting plate 230 and the bending angle between the support portion 110 and the bent portion 120, as long as the cross-sectional dimension of the mounting portion 210 is not larger than the cross-sectional dimension of the support portion 110.

[0061] Since one end of the fastener 400 is connected to the reinforcing member 300 and the other end is connected to the support portion 110 of the first mounting member 100, the vibration and impact load from the suspension assembly 700 is applied vertically to the support portion 110 after passing through the connector 500 and the fastener 400 along the height direction of the vehicle. This avoids the problem of torque and bending moment easily generated due to the deviation of the vibration and impact load, optimizes the load transmission path, and improves the force transmission efficiency of the suspension mounting bracket.

[0062] Furthermore, the support connection points of the suspension mounting bracket are actually located on the two bends 120. The "U"-shaped structure formed by the first mounting member 100 and the mounting part 210 of the second mounting member 200 are superimposed to form a double-layer "U"-shaped support structure. The cross-sectional dimension of the mounting part 210 is not larger than the cross-sectional dimension of the support part 110, which makes the overall suspension mounting bracket a strong support structure with a larger bottom and a smaller top. This design helps to reduce the deformation of the suspension mounting bracket when it is subjected to force on the vehicle body longitudinal beam 600, enhance the overall dynamic stiffness, improve the vehicle's noise, vibration, and ride comfort (NVH) performance, and achieve better force transmission.

[0063] like Figure 3 As shown, in some embodiments, the second mounting member 200 includes a back plate 220 and mounting plates 230 disposed at opposite ends of the mounting portion 210. The mounting plates 230 are connected to at least one of the first mounting member 100 and the vehicle body longitudinal beam 600. The back plate 220 is located on the same side of the mounting plates 230 and the mounting portion 210, and the back plate 220 is connected to both the mounting plates 230 and the mounting portion 210. The back plate 220 is configured to, together with the mounting portion 210, the mounting plates 230 and the vehicle body longitudinal beam 600, form a closed or semi-closed box-shaped structure.

[0064] In the above embodiments, the second mounting component 200 is a one-piece die-cast metal part, and the cross-sectional shape of the mounting plate 230 and the mounting part 210 is approximately "U"-shaped to facilitate cooperation with the support part 110 of the first mounting component 100. Specifically, the mounting plate 230 is welded to the bent part 120 of the first mounting component 100, or the mounting plate 230 is welded to the vehicle body longitudinal beam 600, or the mounting plate 230 is welded to both the bent part 120 of the first mounting component 100 and the vehicle body longitudinal beam 600.

[0065] When the mounting plate 230 is welded to both the bend 120 and the vehicle longitudinal beam 600, to avoid the height difference caused by the simultaneous contact of the mounting plate 230 with both the bend 120 and the vehicle longitudinal beam 600, the plane of the mounting plate 230 has a recessed portion to accommodate the bend 120. Of course, in some embodiments, the mounting plate 230 and the bend 120, and the mounting plate 230 and the vehicle longitudinal beam 600, can also be connected by common bolts; this is not an absolute limitation in the embodiments of this application.

[0066] When the second mounting member 200 is connected to the first mounting member 100 and the vehicle body longitudinal beam 600, the back plate 220 of the second mounting member 200 extends to below the mounting surface where the vehicle body longitudinal beam 600 is located. Thus, the back plate 220, the mounting part 210, the mounting plate 230 and the vehicle body longitudinal beam 600 can jointly form a closed or semi-closed box structure.

[0067] By forming a box-shaped structure together with the back plate 220, mounting plate 230, first mounting member 100 and body longitudinal beam 600, the vibration load of the engine is transferred to the suspension mounting bracket through the suspension assembly 700. The vibration load can be transferred to the body longitudinal beam 600 through the box-shaped structure fixing member 400 via the first mounting member 100, or directly through the back plate 220 of the second mounting member 200. This achieves a multi-path load transfer design, disperses stress distribution, and avoids the problem of local stress concentration in the body longitudinal beam 600.

[0068] The box-shaped structure enhances the suspension mount's resistance to bending and torsion under engine vibration and impact loads, achieving lightweight design while maintaining overall structural rigidity. Furthermore, the enclosed or semi-enclosed box-shaped structure itself forms internal cavities, which can alter the natural frequency of the suspension mount, preventing resonance between the mount and engine excitation. This better suppresses vibration wave transmission and improves the vehicle's NVH performance.

[0069] Furthermore, the back plate 220 extends in a direction away from the mounting portion 210 to form a first connecting portion 221, which is used to connect with the vehicle body longitudinal beam 600.

[0070] Here, the first connecting part 221 is the part of the back plate 220 that extends below the mounting surface of the body longitudinal beam 600. The first connecting part 221 is welded and fixed to the side of the body longitudinal beam 600. As a result, the box-shaped structure can effectively disperse stress distribution. The vibration load from the suspension assembly 700 can be directly transmitted downward through the fixing member 400, or it can be transmitted laterally to the body longitudinal beam 600 through the first connecting part 221. This is beneficial to enhancing the torsional stiffness and lateral stability of the suspension mounting bracket.

[0071] In some embodiments, the mounting plate 230 is bent in the direction toward the mounting portion 210 to form a second connecting portion 231. The second connecting portion 231 on one of the two mounting plates 230 is used to connect with the longitudinal beam surface 610 of the vehicle body longitudinal beam 600, and the second connecting portion 231 on the other of the two mounting plates 230 is used to connect with the wheel arch reinforcement plate 800.

[0072] In the above embodiments, one or more second connecting portions 231 can be provided on each mounting plate 230. The force range of the suspended mounting bracket is extended to the longitudinal beam facade 610 and the wheel cover reinforcing plate 800 through the second connecting portions 231, thereby realizing the decomposition, diffusion and efficient transmission of multi-directional loads, and the force transmission efficiency is higher.

[0073] Here, the bending angle of the second connecting part 231 relative to the mounting plate 230 can be flexibly adjusted according to the actual design scenario. Generally, the second connecting part 231 is welded to the longitudinal beam surface 610, or the second connecting part 231 is welded to the wheel cover reinforcing plate 800.

[0074] Furthermore, such as Figure 6 As shown, the mounting portion 210 is bent along the side opposite to the back plate 220 to form a third connecting portion 211, which is used to connect with the wheel arch reinforcement plate 800. The aforementioned third connecting portion 211 and the second connecting portion 231 of the mounting plate 230 are jointly connected to the wheel arch reinforcement plate 800. The second connecting portion 231 of the mounting plate 230, the first connecting portion 221 of the back plate 220, and the third connecting portion 211 of the mounting portion 210 are respectively connected to different positions of the wheel arch reinforcement plate 800 and the longitudinal beam, thereby forming a multi-point support connection structure in space. This is beneficial to enhance the connection stability of the suspension mounting bracket, and at the same time, it can reduce the deformation of the suspension mounting bracket under vibration and improve dynamic stiffness.

[0075] like Figure 5 As shown, in some embodiments, the reinforcing member 300 is fitted and connected to the mounting portion 210, and at least one edge of the reinforcing member 300 is bent to form a flange 310.

[0076] The aforementioned reinforcing member 300 is welded to the lower side of the mounting part 210. The flange 310 on the reinforcing member 300 is approximately added as a reinforcing rib on the body of the reinforcing member 300, which can enhance the local strength and deformation resistance of the reinforcing member 300.

[0077] In some embodiments, the fixing member 400 is a sleeve with an internal threaded hole, and the connecting member 500 passes through the mounting part 210 and is threadedly connected to the fixing member 400. The connecting member 500 is a bolt that passes through the suspension assembly 700 and the fixing member 400.

[0078] In related technologies, direct welding of the second mounting component 200 and the fixing component 400 can easily cause stress concentration on the surface of the parts, resulting in deformation of the mounting portion 210 of the second mounting component 200 and failure of the mating surface between the mounting portion 210 and the suspension assembly 700 to meet the precision requirements. Therefore, a reinforcing component 300 is added between the second mounting component 200 and the fixing component 400. The second mounting component 200 is first spot-welded to the reinforcing component 300, one end of the fixing component 400 is welded to the reinforcing component 300, and the other end is welded to the support portion 110 of the first mounting component 100, forming a fixed support structure to prevent the fixing component 400 from vibrating with the suspension assembly 700 and effectively improve the NVH performance of the vehicle.

[0079] In some embodiments, a mounting hole is formed at the top of the mounting portion 210 of the second mounting member 200. The distance from the center of the mounting hole to the rounded corner feature surface of the peripheral bend must meet the mounting surface requirements of the suspension assembly 700 for the mounting portion 210. The mounting hole is used to pass through the connector 500. The size requirements of the mounting surface can be determined according to the design scenario of different vehicles, and are not absolutely limited in this embodiment.

[0080] The lower side of the mounting part 210 is first spot welded to the reinforcing member 300. A 15mm diameter hole is opened on the end face of the reinforcing member 300. The upper end of the fixing member 400 is welded to the opening of the reinforcing member 300. The overall length of the fixing member 400 is 39mm, the top diameter of the fixing member 400 is 25mm, and the thread is M12*1.75. Finally, the first mounting part 100 is installed. A 20mm diameter hole is opened on the top of the support part 110 of the first mounting part 100, and it is circumferentially welded to the lower end of the fixing member 400.

[0081] To improve the vehicle's NVH performance and increase the dynamic stiffness of the suspension mount bracket, the second mounting component 200 has a plate thickness of 1.6mm; to improve the overall structural strength, the first mounting component 100 has a plate thickness of 2mm. After the overall welding is completed, a semi-enclosed box-shaped structure is formed and welded to the side and vertical surface 610 of the body longitudinal beam 600, thereby enhancing the stability of the entire suspension mount bracket.

[0082] Another embodiment of this application provides a vehicle including a body longitudinal beam 600, a suspension assembly 700, and a suspension mounting bracket of any of the above embodiments; the body longitudinal beam 600 and the suspension assembly 700 are connected by at least two suspension mounting brackets.

[0083] Since the vehicle includes the suspension mount bracket in any of the above embodiments, it has all the advantages of a suspension mount bracket.

[0084] like Figure 2As shown, in some embodiments, the suspension assembly 700 is connected to the vehicle longitudinal beam 600 through two spaced-apart suspension mounting brackets. Since there are multiple mounting points for different components distributed on the vehicle longitudinal beam 600, the back plate 220 of the suspension mounting bracket can be designed to avoid the area of ​​the mounting points, as long as it does not affect the connection of the suspension mounting bracket to the vehicle longitudinal beam 600.

[0085] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only.

[0086] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
