DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the schemes of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other different manners from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, not all the embodiments.

[0034] Referring to Figures 1 to 6 As shown in the figure, the present embodiment provides a suspension spring mounting structure (hereinafter referred to as spring mounting structure), which comprises a mounting seat 1, a reinforcing structure 2 and a spring seat 3 for mounting a suspension spring.

[0035] Specifically, referring to Figures 3 to 5 As shown in the figure, the mounting seat 1 is connected to the bottom end of the longitudinal beam 7, and the spring seat 3 is connected to the bottom end of the mounting seat 1. The side of the mounting seat 1 facing the longitudinal beam 7 has a mounting cavity 4, the reinforcing structure 2 is arranged in the mounting cavity 4, and the reinforcing structure 2 is fixed relative to the cavity wall of the mounting cavity 4 and the longitudinal beam 7.

[0036] When specifically implemented, the mounting seat 1 can be welded on the longitudinal beam 7, and the spring seat 3 can be welded on the mounting seat 1, which is convenient for connection and has high connection strength. Of course, the mounting seat and the longitudinal beam can also be connected by bolts or other connection methods, as long as they are relatively fixed. The same is true for the mounting seat and the spring seat.

[0037] Wherein, the reinforcing structure 2 and the longitudinal beam 7, and the reinforcing structure 2 and the cavity wall of the mounting cavity 4 can also be connected together by welding, for example.

[0038] The mounting base 1 is fixed at the bottom end of the longitudinal beam 7, and the mounting base 1 and the longitudinal beam 7 are connected to form an integral structure. The mounting cavity 4 is arranged on the side of the mounting base 1 facing the longitudinal beam 7, the reinforcing structure 2 is arranged in the mounting cavity 4, and the bottom end of the reinforcing structure 2 is fixedly connected with the longitudinal beam 7. At the same time, the reinforcing structure 2 is also fixedly connected with the cavity wall of the mounting cavity 4. In this way, the mounting base 1 and the longitudinal beam 7 are further connected to form an integral structure through the reinforcing structure 2, that is, the integrity and connection strength between the mounting base 1 and the longitudinal beam 7 are improved through the reinforcing structure 2, so as to strengthen the structural strength and stability of the mounting base 1.

[0039] Since the spring seat 3 is fixed at the bottom end of the mounting base 1, that is, the spring seat 3 is fixed at the end of the mounting base 1 away from the longitudinal beam 7. On the basis of the structural strength and stability of the mounting base 1 being enhanced by the reinforcing structure 2, the structural strength and dynamic stiffness of the spring seat 3 are also improved and enhanced, so as to improve the dynamic stiffness and deformation resistance of the spring mounting structure, and reduce the road noise in the cockpit.

[0040] By arranging the mounting cavity 4 on the mounting base and fixing the reinforcing structure 2 in the mounting cavity 4, the mounting cavity 4 has a certain protective effect on the reinforcing structure 2, prolongs the service life of the reinforcing structure 2, and at the same time, the mounting cavity 4 also has a certain folding effect on the reinforcing structure 2, thereby enhancing the structural strength and stability of the reinforcing structure 2 itself.

[0041] At the same time, the mounting cavity 4 and the reinforcing structure 2 cooperate to form a stable connection structure, and the cooperation of the two has a certain effect of strengthening and damping and energy absorption, thereby enhancing the mounting strength and stiffness of the suspension spring mounting structure of the embodiment, improving the vibration damping capability, and further reducing the road noise in the cockpit.

[0042] In some implementations, the reinforcing structure 2 can be made of metal material, which has high structural strength, excellent load-bearing performance, and good force transmission effect.

[0043] The spring mounting structure provided by the embodiment is characterized in that the mounting base 1 is connected to the bottom end of the longitudinal beam 7, the spring seat 3 is connected to the bottom end of the mounting base 1, the side of the mounting base 1 facing the longitudinal beam 7 has a mounting cavity 4, the reinforcing structure 2 is arranged in the mounting cavity 4, and the reinforcing structure 2 is fixed relative to the cavity wall of the mounting cavity 4 and the longitudinal beam 7. The mounting cavity 4 is formed on the side of the mounting base 1 facing the longitudinal beam 7, and the reinforcing structure 2 is arranged in the mounting cavity 4, so that the reinforcing structure 2 is fixed relative to the cavity wall of the mounting cavity 4 and the top end of the reinforcing structure 2 is also fixed relative to the longitudinal beam 7. In this way, the reinforcing structure 2 not only enhances the structural strength of the mounting base 1, but also enhances the connecting strength between the mounting base 1 and the longitudinal beam 7, so that the mounting base 1 has high strength, dynamic stiffness and stability, the structural strength and dynamic stiffness of the spring seat 3 connected thereto are improved, the dynamic stiffness and deformation resistance of the suspension spring mounting structure are improved, and the road noise in the cockpit is reduced. At the same time, the mounting cavity 4 is formed on the mounting base 1, and the reinforcing structure 2 is accommodated in the mounting cavity 4. The mounting cavity 4 not only protects the reinforcing structure 2 and helps to prolong the service life of the reinforcing structure 2, but also forms a stable connecting structure with the reinforcing structure 2, which has the effects of reinforcing damping and energy absorption, thereby enhancing the mounting strength and stiffness of the suspension spring mounting structure of the embodiment, improving the vibration damping capability, and further reducing the road noise in the cockpit.

[0044] In some embodiments, with reference to Figure 1 、 Figure 5 and Figure 6 The reinforcing structure 2 includes a first reinforcing plate 21 and two oppositely arranged second reinforcing plates 22. The first reinforcing plate 21 is connected, such as welded, to the bottom end face of the longitudinal beam 7 (i.e., the bottom wall of the longitudinal beam 7), and the two second reinforcing plates 22 are respectively connected to the two sides in the width direction of the first reinforcing plate 21, both of which extend away from the longitudinal beam 7 and are fixedly connected to the cavity wall of the mounting cavity 4. The structure is simple, easy to manufacture, convenient and stable to connect, and has good load-bearing capacity.

[0045] The reinforcing structure 2 is arranged as the first reinforcing plate 21 and the two second reinforcing plates 22, the first reinforcing plate 21 is fixed to the bottom wall of the longitudinal beam 7, and the two second reinforcing plates 22 are respectively connected to the two sides in the width direction of the first reinforcing plate 21 and extend away from the longitudinal beam 7. The end of each of the two second reinforcing plates 22 away from the longitudinal beam 7 is fixedly connected to the cavity wall of the mounting cavity 4. That is, the first reinforcing plate 21 is fixed to the bottom wall of the longitudinal beam 7, and the first reinforcing plate 21 is also spaced apart from and fixedly connected to the inner bottom wall of the mounting base 1 through the two second reinforcing plates 22. The structure is simple, convenient and stable to connect, has good dynamic stiffness and deformation resistance, excellent load-bearing capacity, and good force transmission effect.

[0046] In a specific implementation, the width direction of the first reinforcing plate 21 can be consistent with the width direction of the longitudinal beam 7.

[0047] In a specific implementation, as shown in Figure 1 , Figure 5 and Figure 6 , the first reinforcing plate 21 and the two second reinforcing plates 22 can jointly enclose a U-shaped buffer space with an opening facing the mounting cavity 4, which increases the force transmission path and the connection joint between the mounting seat 1 and the longitudinal beam 7, thereby improving the connection strength between the mounting seat 1 and the longitudinal beam 7, so that the structural strength and stability of the mounting seat 1 are higher, the dynamic stiffness and the ability to resist deformation of the mounting seat 1 are improved, thereby improving the structural strength and dynamic stiffness of the spring seat 3, improving the dynamic stiffness and the ability to resist deformation of the spring mounting structure of the embodiment, and reducing the road noise in the cockpit.

[0048] In some implementations, the first reinforcing plate 21 and the two second reinforcing plates 22 can be integrally formed, which has good integrity and better dynamic stiffness.

[0049] Among them, the first reinforcing plate 21 can be welded on the bottom wall of the longitudinal beam 7, and the two second reinforcing plates 22 can be welded on the inner bottom wall of the mounting cavity 4.

[0050] In some embodiments, as shown in Figure 1 , Figure 5 and Figure 6 , one end of the two second reinforcing plates 22 away from the first reinforcing plate 21 is bent in a direction away from each other to form a first flange 51, and the two first flanges 51 are fixedly connected with the cavity wall of the mounting cavity 4 away from the longitudinal beam 7 (i.e. the bottom cavity wall of the mounting cavity, or the inner bottom wall of the mounting cavity).

[0051] By respectively providing the first flange 51 at one end of the two second reinforcing plates 22 away from the first reinforcing plate 21, and the two first flanges 51 are fixedly connected with the inner bottom wall of the mounting cavity 4, this arrangement increases the connection joint area between the second reinforcing plate 22 and the cavity wall of the mounting cavity 4, thereby improving the connection strength between the second reinforcing plate 22 and the mounting seat 1, so that the stability and dynamic stiffness of the reinforcing structure 2 are higher, and the structural reinforcing effect on the mounting seat 1 is better.

[0052] In a specific implementation, the two first flanges 51 extend from the second reinforcing plate 22 where they are located in a direction away from each other, so that the two first flanges 51 are symmetrically arranged, so that the structural stability of the reinforcing structure 2 is better, and the structural reinforcement of the mounting seat 1 is better.

[0053] In some embodiments, as shown in Figure 1 and Figure 6As shown, at least one side of each second reinforcing plate 22 is provided with a second flange 52, and the second flange 52 is fixedly connected with the cavity wall of the mounting cavity 4 intersecting with the longitudinal beam 7 (i.e. the side cavity wall of the mounting cavity 4).

[0054] By providing the second flange 52 on the side wall of the second reinforcing plate 22 and connecting the second flange 52 to the side wall cavity wall of the mounting cavity 4, the connection joint of the second reinforcing plate 22 and the mounting cavity 4 is increased, and the structural stability of the reinforcing structure 2 is further improved, which better enhances the structure of the mounting seat 1, so that the dynamic stiffness and deformation resistance of the spring mounting structure are further reduced, and the road noise in the cockpit is further reduced.

[0055] In some embodiments, referring to Figures 1 to 4 As shown, the mounting seat 1 includes a bottom plate 11 and two side plates 12. The two side plates 12 can be connected to the opposite two side walls of the bottom plate 11 along the length direction of the longitudinal beam 7, respectively, and the ends of the two side plates 12 away from the bottom plate 11 are fixed to the bottom surface of the longitudinal beam 7. The bottom plate 11 and the two side plates 12 together enclose the mounting cavity 4, which is simple in structure, easy to manufacture, convenient and stable to connect.

[0056] In specific implementation, the ends of the two second reinforcing plates 22 away from the first reinforcing plate 21 are fixedly connected with the bottom plate 11, the two first flanges 51 are fixedly connected with the bottom plate 11, and the second flange 52 is fixedly connected with the side plate 12.

[0057] In some embodiments, referring to Figures 1 to 4 As shown, the ends of the two side plates 12 away from the bottom plate 11 extend in a direction away from each other and are respectively formed with a third flange 53, and the third flange 53 is fixedly connected with the bottom end surface of the longitudinal beam 7.

[0058] By providing the third flange 53 on the end of the side plate 12 away from the bottom plate 11 and connecting the third flange 53 to the bottom end surface of the longitudinal beam 7, the connection area of the side plate 12 and the longitudinal beam 7 is increased, and the connection strength of the mounting seat 1 and the longitudinal beam 7 is further increased, so that the structural strength and dynamic stiffness of the mounting seat 1 are higher, and the deformation resistance is stronger. The structural stability and dynamic stiffness of the spring seat 3 provided on the mounting seat 1 are improved, and the road noise in the cockpit is further reduced.

[0059] In some embodiments, referring to Figures 1 to 5 As shown, the spring mounting structure further includes a support seat 6, and the support seat 6 is located on one side of the longitudinal beam 7. The support seat 6 can be arranged on one side of the longitudinal beam 7 along the thickness direction of the longitudinal beam 7, for example. The top end of the support seat 6 is fixedly connected with the longitudinal beam 7, and the bottom end of the support seat 6 is located in the mounting cavity 4 and is fixedly connected with the cavity wall of the mounting cavity 4.

[0060] By arranging the support seat 6 on one side of the longitudinal beam 7 along the thickness direction of the longitudinal beam 7, the top end of the support seat 6 is fixedly connected with the longitudinal beam 7, and the bottom end of the support seat 6 is located in the mounting cavity 4 and is fixedly connected with the cavity wall of the mounting cavity 4. In this way, the mounting seat 1 is also connected with the longitudinal beam 7 through the support seat 6, and the mounting seat 1 and the longitudinal beam 7 are further connected to form an integral structure, that is, the integrality and the connection strength between the mounting seat 1 and the longitudinal beam 7 are further improved through the support seat 6, so that the structural strength and stability of the mounting seat 1 are improved, the dynamic stiffness and the deformation resistance are better, and the road noise in the cockpit is further reduced.

[0061] In specific implementation, the support seat 6 can be welded on the side wall of the longitudinal beam 7, and the support seat 6 and the cavity wall of the mounting cavity 4 can be welded together, for example.

[0062] It should be noted that the thickness direction of the longitudinal beam 7 can be understood as the direction from the top end face of the longitudinal beam 7 to the bottom end face of the longitudinal beam 7, and the thickness direction of the longitudinal beam 7 is consistent with the height direction of the vehicle body, as shown by the double-headed straight line in Figure 5 .

[0063] In some embodiments, as shown in Figures 1 to 5 , the support seat 6 is a support wall, the top end of the support wall is connected to the side wall of the longitudinal beam 7 and is relatively fixed with the longitudinal beam 7, and the bottom end of the support wall is fixedly connected with at least the bottom cavity wall of the mounting cavity 4. The structure is simple, easy to manufacture, convenient and stable to connect, and has good bearing capacity.

[0064] In some embodiments, as shown in Figure 1 and Figure 5 , the bottom end of the support wall is provided with at least two fourth flanges 54, and the at least two fourth flanges 54 are respectively arranged on the two sides of the support wall and are fixedly connected with the cavity wall of the mounting cavity 4. Specifically, at least one fourth flange extends towards the direction close to the mounting cavity 4, and at least one fourth flange extends away from the mounting cavity 4, so that the two sides of the support wall are connected with the cavity wall of the mounting cavity 4 from different directions, and the connection strength between the support wall and the cavity wall of the mounting cavity 4 is increased.

[0065] In specific implementation, part of the fourth flanges 54 are fixedly connected with the bottom cavity wall of the mounting cavity 4, and part of the fourth flanges 54 are fixedly connected with the side cavity wall of the mounting cavity 4, which is convenient and stable to connect.

[0066] By arranging the fourth flanges 54 on the support wall, the connection area between the support wall and the mounting seat 1 is increased, so that the connection strength between the support wall and the mounting seat 1 is higher. Since the support wall is fixedly connected with the longitudinal beam 7, the connection strength between the mounting seat 1 and the longitudinal beam 7 is higher, the dynamic stiffness and the deformation resistance are further improved, and the road noise in the cockpit is further reduced.

[0067] In some implementations, the fourth flange connected with the bottom cavity wall of the mounting cavity 4 can extend towards the direction away from the reinforcing structure 2, and the fourth flange connected with the side cavity wall of the mounting cavity 4 can extend towards the direction close to the reinforcing structure 2, so that the space utilization is higher, the connection is convenient, and the assembly is facilitated.

[0068] In some embodiments, referring to FIGS. 1 and 2, the support wall is provided with a fifth flange 55 away from the mounting cavity 4, and the side wall of the longitudinal beam 7 is provided with a beam flange 71 extending outward, and the fifth flange 55 is fixedly connected with the bottom surface of the beam flange 71.

[0069] By providing the fifth flange 55 on the support wall and fixedly connecting the fifth flange 55 with the beam flange 71 of the side wall of the longitudinal beam 7, the connection area between the support wall and the longitudinal beam 7 is increased, so that the connection strength between the support wall and the longitudinal beam 7 is higher. Since the support wall is also fixedly connected with the mounting seat 1, the connection strength between the mounting seat 1 and the longitudinal beam 7 is higher, the dynamic stiffness and the ability to resist deformation are further improved, and the road noise in the cockpit is further reduced.
