Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment technology, and in particular to a suspension mounting structure and a vehicle. Background Technology

[0002] In a non-load-bearing body structure, the body and the mounting bracket are typically fixed together by two sets of bolts with different tightening directions. One set of bolts is fixed to the upper surface of the mounting bracket, with the bolts arranged in a unidirectional, regular pattern, and the body strength easily meets the requirements. The other set of bolts is connected to the mounting bracket at two points and transmits the mounting bracket force to the body during vehicle operation. The mounting point group on the body needs to have strong dynamic stiffness. Currently, the reinforcement of the mounting bracket at the corresponding position on the body is mostly achieved by accumulating material thickness, that is, by stacking two or more layers of sheet metal to increase the thickness of the mounting plate to 5.5mm-6.5mm to improve the dynamic stiffness of the mounting point. However, due to the limitations of the connection process, it is difficult to achieve an effective connection for thick plates by spot welding, and arc welding is required for fixation. However, arc welding is not only more difficult to operate, but it is also prone to thermal deformation in the surrounding area, causing non-linear torque attenuation of the mounting parts on the mounting surface, and there is a significant risk of sheet metal failure and cracking during vehicle road testing.

[0003] Therefore, how to improve the installation stability and ease of installation of the fixed structure suspended on the vehicle body is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a suspension mounting structure to improve the installation stability and ease of installation on the vehicle body.

[0005] Another objective of this invention is to provide a vehicle that includes the above-described suspension mounting structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A suspension mounting structure, comprising:

[0008] A fixed plate and bushings, wherein several bushings are spaced apart for suspension and fixation, the bushings pass through the fixed plate and are welded to the fixed plate;

[0009] The support plate and the reinforcing plate respectively support the two ends of the bushing in the axial direction and are fixedly connected to the fixing plate and the bushing to form an integral structure; both the support plate and the reinforcing plate are provided with mating holes coaxial with the center hole of the bushing.

[0010] Preferably, in the above-mentioned suspension mounting structure, the bushing has a material thickness of 6mm-9mm and is fixed to the fixing plate by arc welding; the fixing plate has a thickness of 1.2mm-2.0mm.

[0011] Preferably, in the above-mentioned suspension mounting structure, the thickness of the support plate is 1.5mm-2.0mm; the thickness of the reinforcing plate is 1.5mm-2.0mm.

[0012] Preferably, in the above-mentioned suspension mounting structure, the connection structure between the support plate and the reinforcing plate is fixed by spot welding.

[0013] Preferably, the above-mentioned suspension mounting structure further includes an outer front panel and an inner front panel, wherein the outer front panel is connected to the reinforcing plate and the inner front panel is connected to the support plate; the outer front panel and the inner front panel are shaped parts and are spot-welded to seal the bushing.

[0014] Preferably, in the above-mentioned suspension mounting structure, the thickness of the outer front panel is 0.7mm-1.2mm; and the thickness of the inner front panel is 0.7mm-1.2mm.

[0015] Preferably, in the above-described suspension mounting structure, the fixing plate includes a U-shaped protrusion that forms a cavity structure with the support plate, and the bushing passes through the protrusion and is connected to the support plate.

[0016] Preferably, in the above-described suspension mounting structure, the reinforcing plate is a plate with bent edges and fastened to the support plate, and the fixing plate and the bushing are disposed in the fastening area of ​​the reinforcing plate and the support plate.

[0017] Preferably, in the above-described suspension mounting structure, the edge of the contact area between the inner front panel and the support plate is provided with sealant.

[0018] A vehicle comprising the suspension mounting structure described in any of the above embodiments.

[0019] As can be seen from the above technical solution, the suspension mounting structure provided by this utility model mainly includes a fixing plate, a bushing, a support plate, and a reinforcing plate. The bushing is used for bolts to pass through. The bushing with a relatively large thickness can provide a stable connection support point for the suspension. At the same time, the bushing can provide a larger connection surface through its axial length, which can more effectively disperse the force exerted by the suspension on the vehicle body, and has a larger mounting contact surface with the vehicle body and the suspension to improve the failure threshold of the suspension mounting structure. The fixing plate is used to fix the bushing, and the bushing passes through the fixing plate and is fixed to the fixing plate by welding. This connection structure allows the bushing to be connected to the fixing plate circumferentially through a weld to form a stable small assembly structure. The support plate and the reinforcing plate support the bushing from both sides of the bushing axially to increase the thickness of the suspension mounting structure in the bushing axial direction, thereby improving the support stability of the suspension mounting structure for the suspension. They can also be independently thickened to achieve single-end connection reinforcement of the bushing, improving the connection effect of the suspension mounting structure. At the same time, the layered structure can be assembled independently, which has a more convenient assembly process compared to thick plate welding. Attached Figure Description

[0023] The core of this utility model lies in disclosing a suspension mounting structure to improve the installation stability and ease of installation on the vehicle body.

[0024] Another key aspect of this invention is providing a vehicle that includes the aforementioned suspension mounting structure.

[0025] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0026] like Figure 1 As shown, the suspension mounting structure provided in this embodiment mainly includes a fixing plate 10, a bushing 20, a support plate 30, and a reinforcing plate 40, to achieve stable fixing and load-bearing of the suspension components, while ensuring the compactness and integrity of the structure for easy placement in a vehicle. Specifically, the bushing 20 is the main load-bearing component for fixing the suspension components. Several bushings are provided according to the installation requirements of the suspension. Typically, a single fixing point includes two spaced and parallel bushings 20. It should be noted that the bushing 20 is used for bolts to pass through. The bushing 20 with a relatively large thickness can provide a stable connection support point for the suspension. At the same time, the bushing 20 can provide a larger connection surface through its axial length, which can more effectively disperse the force exerted by the suspension on the vehicle body, and has a larger installation contact surface with the vehicle body and the suspension to improve the failure threshold of the suspension mounting structure.

[0027] The fixing plate 10 is used to fix the bushing 20. Specifically, the bushing 20 passes through the fixing plate 10 and is fixed to the fixing plate 10 by welding. It should be noted that this welding fixing method can connect the outer wall of the bushing 20 to the fixing plate 10 through welds, ensuring the connection strength and stability between the bushing 20 and the fixing plate 10, and preventing the connection from loosening due to vibration or impact during long-term use. As a basic support component, the fixing plate 10 needs to meet the requirements of load-bearing capacity and rigidity to adapt to the installation and use requirements of the suspension components; and for vehicle models with more complex stress conditions, the fixing plate 10 can be thickened to improve its support effect on the bushing 20.

[0028] It should be noted that the fixing plate 10 can also serve as a process aid for fixing the bushing 20. In fact, during the assembly of the suspension mounting structure, the bushing 20 is first welded and fixed to the fixing plate 10 separately. The fixing plate 10 maintains the parallelism of the bushing 20 and the coaxiality of the holes of the front and rear components through the pre-drilled mounting holes for the bushing 20 to pass through, thereby ensuring the accuracy of the suspension mounting position.

[0029] Furthermore, the suspension mounting structure provided in this embodiment of the present invention also includes a support plate 30 and a reinforcing plate 40. The support plate 30 and the reinforcing plate 40 respectively support the two ends of the bushing 20 in the axial direction and are fixedly connected to the fixing plate 10 and the bushing 20 as an integral structure. The support plate 30 and the reinforcing plate 40 can provide additional support and reinforcement for the bushing 20, enhancing the load-bearing capacity and stability of the entire suspension mounting structure. At the same time, the support at both ends of the bushing 20 in the axial direction can also reduce the risk of local sheet metal deformation caused by the maximum torque applied during the installation process, which is generally 80 N·m-100 N·m. Meanwhile, both the support plate 30 and the reinforcing plate 40 are provided with mating holes 410 coaxial with the center hole of the bushing 20. The above structure allows the bolts for fastening the suspension components to pass smoothly through the mating holes 410 and cooperate with the bushing 20 for fixation, while also facilitating the installation and disassembly of the suspension components.

[0030] It should be noted that the suspension mounting structure provided in the above embodiments, while providing stable support and force transmission through the bushing 20, also strengthens the bushing 20 through multiple stacked plates. These stacked plates are located at different axial positions on the bushing 20, namely the ends and the middle region, allowing for step-by-step welding and fixing of individual components without requiring complete contact. Furthermore, compared to existing support structures, the stacked structure allows for thinner sheet metal in individual components, resulting in simpler manufacturing processes and welding methods. In some embodiments of this invention, the bushing 20 has a thickness of 6mm-9mm. This thickness range ensures that the bushing 20 possesses sufficient strength and rigidity to match the approximately 6mm thickness of existing suspension assembly plates, thus meeting the requirements for fixing and bearing the load of the suspension components. Meanwhile, given the thickness of the bushing 20, ordinary spot welding cannot guarantee an effective weld nugget and penetration depth, thus failing to ensure effective connection strength. Therefore, the bushing 20 is fixedly connected to the fixing plate 10 by arc welding. Arc welding is a common welding method with advantages such as high welding quality and high connection strength, effectively ensuring the stability and reliability of the connection between the bushing 20 and the fixing plate 10. It should also be noted that the thickness of the fixing plate 10 is designed to be 1.2mm-2.0mm. This thickness range meets the load-bearing capacity and rigidity requirements of the fixing plate 10, while also helping to control the weight and cost of the entire suspension installation structure.

[0031] Based on the above embodiments, the thickness of the support plate 30 is designed to be 1.5mm-2.0mm, and the thickness of the reinforcing plate 40 is also designed to be 1.5mm-2.0mm, so as to provide uniform support for the bushing 20 from both sides. This thickness range can meet the support requirements. At the same time, combined with the fixing plate 10, the axial support strength of the suspension mounting structure in the bushing 20 is similar to that of sheet metal parts with a thickness of about 6mm in the prior art, thus ensuring the load-bearing capacity and stability of the entire suspension mounting structure.

[0032] It should be noted that since the support plate 30 and reinforcing plate 40 in the above structure are both thin plate structures, effective weld penetration can be achieved through spot welding. Therefore, in some embodiments of this utility model, the connecting structures on the support plate 30 and reinforcing plate 40 are specifically fixed by spot welding. It should be noted that the connecting structures here include the bushing 20, the fixing plate 10, and the shaping structure, which are in contact with the support plate 30 or reinforcing plate 40. Spot welding has advantages such as fast welding speed, high welding quality, and high connection strength, and it is convenient to operate. That is, in the suspension mounting structure provided in this utility model embodiment, only the connection area of ​​the bushing 20 and the fixing plate 10 needs to be arc welded. Other related plates can be connected by spot welding due to thickness optimization. Compared with the extensive arc welding results in the prior art, the welding assembly operation is simpler. Furthermore, spot welding also has advantages such as small welding deformation and small welding area, which helps maintain the shape and dimensional accuracy of the support plate 30 and reinforcing plate 40, thereby ensuring the accuracy and performance of the entire suspension mounting structure.

[0033] Furthermore, in some embodiments of this utility model, the suspension mounting structure further includes a front outer panel 50 and a front inner panel 60, wherein the front outer panel 50 is fixedly connected to the reinforcing plate 40, and the front inner panel 60 is fixedly connected to the support plate 30. The front outer panel 50 and the front inner panel 60 are styling parts to meet the structural and styling requirements of the vehicle body. Preferably, the thickness of the front outer panel 50 is 0.7mm-1.2mm, and the thickness of the front inner panel 60 is 0.7mm-1.2mm. Based on the wall thickness of the front outer panel 50 and the front inner panel 60, the front outer panel 50 and the front inner panel 60 can be spot-welded together to seal the bushing 20. It should be noted that the front outer panel 50 and the front inner panel 60 provide additional protection and sealing for the suspension mounting structure, preventing dust, moisture and other external environmental factors from eroding and affecting the suspension mounting structure, thereby extending its service life and performance stability. At the same time, as styling components, the front outer panel 50 and the front inner panel 60 can be designed and adjusted according to actual application needs to meet different appearance and functional requirements.

[0034] Furthermore, in the suspension mounting structure provided in this embodiment of the present invention, the fixing plate 10 includes a U-shaped protrusion 110. After the fixing plate 10 is fixedly connected to the support plate 30, the protrusion 110 and the support plate 30 form a cavity structure, and the bushing 20 passes through the cavity formed by the protrusion 110 and the support plate 30 and is connected to the support plate 30. The U-shaped protrusion 110 design can provide additional support and fixing space for the bushing 20, enhancing its stability on the fixing plate 10. At the same time, it can increase the fixing area of ​​the bushing 20 in its axial direction without excessively increasing the weight of the fixing plate 10, making it less prone to deformation or damage during the fixing and bearing of the suspension component.

[0035] Furthermore, in some embodiments of this utility model, the reinforcing plate 40 is a plate structure with bent edges, and the reinforcing plate 40 is fastened to the support plate 30. The fixing plate 10 and the bushing 20 are disposed within the fastening area of ​​the reinforcing plate 40 and the support plate 30. The design of the edge-bent reinforcing plate 40 can increase its rigidity and strength, making it more stable and reliable in the process of fixing and bearing the suspended components; while the fastening connection method can generate more contact area between the reinforcing plate 40 and the support plate 30, resulting in a tighter connection effect and avoiding the problem of loosening due to vibration or impact of the suspension. The fixing plate 10 and the bushing 20 are disposed within the fastening area, thus receiving better support and protection, ensuring their stability and reliability during use.

[0036] It should be further noted that sealant is also provided at the edge of the contact area between the inner front panel 60 and the support plate 30. The sealant has good adhesion and sealing properties, and can form an effective sealing layer in the contact area to ensure the sealing and reliability of the suspension mounting structure. It prevents dust, moisture, and other external environmental factors from entering the interior of the suspension mounting structure through gaps in the contact area, thereby better protecting the suspension mounting structure from external environmental erosion and influence.

[0037] Furthermore, this utility model embodiment also provides a vehicle that includes the suspension mounting structure provided in any of the above embodiments to achieve mounting on the vehicle. It should be noted that since the suspension mounting structure has the technical effects provided in any of the above embodiments, the vehicle also has the above technical effects, and will not be described again here.
