The Watt's link 8 is mounted on the cross member 7, and a link portion of the Watt's link 8 is connected to the frame longitudinal member 6. The Watt's link 8 can resist the lateral force between the rear wheels and the vehicle body to improve the lateral rigidity of the vehicle.
[0003] Since the Watt's link 8 is mounted on the cross member 7, the cross member 7 needs to be larger in size to carry the Watt's link 8, which makes the cross member 7 heavier. At the same time, the Watt's link 8 exerts a greater force on the cross member 7, making the cross member 7 susceptible to fatigue damage. Utility Model Content

[0010] In a possible design, the first mounting bracket includes a first connecting portion connected to the first arm portion, the first connecting portion is bent relative to the first arm portion, and the first connecting portion is connected to the top surface of the beam.
[0011] In one possible design, the mounting bracket includes a third mounting bracket and a fourth mounting bracket, and there is a crossbeam on the floor.

[0048] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0049] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0050] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.
[0051] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.
[0052] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.
[0053] Figure 1 This is a structural diagram of a vehicle suspension in the prior art. Figure 1As shown, the vehicle has a rear suspension including a frame longitudinal member 6, a cross member 7, and a Watt's link 8. The Watt's link 8 is mounted on the cross member 7, and a link portion of the Watt's link 8 is connected to the frame longitudinal member 6. The Watt's link 8 can resist the lateral force between the rear wheels and the vehicle body to improve the lateral rigidity of the vehicle.
[0054] Since the Watt's link 8 is mounted on the cross member 7, the cross member 7 needs to be larger in size to carry the Watt's link 8, which makes the cross member 7 heavier. At the same time, the Watt's link 8 exerts a greater force on the cross member 7, making the cross member 7 susceptible to fatigue damage.
[0055] The present application provides a vehicle, such as Figure 2 and Figure 4 As shown, the vehicle includes: a floor 5, a rear suspension and a mounting bracket. The rear suspension has a Watt's link 8. The mounting bracket is connected to the floor 5. The Watt's link 8 is rotatably connected to the mounting bracket.
[0056] In this application, if Figure 2 and Figure 4 As shown, Watt's link 8 is rotatably connected to floor panel 5 via a mounting bracket. Floor panel 5 provides stable support for Watt's link 8, thereby facilitating its installation. Since Watt's link 8 need not be mounted on cross member 7, the cross member 7 can be appropriately reduced in size and weight. Furthermore, there is no need for a structure on cross member 7 for connecting with Watt's link 8, simplifying its structure. Furthermore, since Watt's link 8 no longer exerts force on cross member 7, cross member 7 is less susceptible to fatigue damage.
[0057] In addition, the mounting bracket has the advantages of simple structure, light weight and high reliability.
[0058] In a specific embodiment, Figure 2 and Figure 3 As shown, the mounting bracket includes a first mounting bracket 1 and a second mounting bracket 2. A crossbeam 51 is provided on the floor 5. Along the longitudinal direction X of the vehicle, the first mounting bracket 1 and the second mounting bracket 2 are connected to the crossbeam 51 from both sides thereof. An installation space is provided between the first mounting bracket 1, the second mounting bracket 2 and the crossbeam 51, and the Watt's link 8 is installed in the installation space.
[0059] In this embodiment, if Figure 2 and Figure 3As shown, the mounting bracket is set in a split form of the first mounting frame 1 and the second mounting frame 2, which can facilitate the production and processing of the mounting bracket and also facilitate the installation and fixation among the mounting bracket, the Watt link 8 and the cross beam 51. The first mounting frame 1 and the second mounting frame 2 are respectively connected to the cross beam 51 from both sides of the cross beam 51 along the length direction X of the vehicle, which can make the contact area between the first mounting frame 1 and the second mounting frame 2 and the cross beam 51 larger and the connection reliability higher.
[0060] Among them, one side of the installation space facing away from the cross beam 51 is connected to the outside, and along the direction away from the cross beam 51, the dimension of the installation space along the length direction X of the vehicle gradually decreases, so that the first mounting frame 1 and the second mounting frame 2 can limit the Watt link 8 and prevent the Watt link 8 from separating from the mounting bracket.
[0061] It can be understood that the mounting bracket can also be an integral structure or integrally formed with the floor 5.
[0062] Specifically, as Figure 3 shown, the first mounting frame 1 has a first body 11 and first arm portions 12. The first arm portions 12 are arranged at both ends of the first body 11. The second mounting frame 2 has a second body 21 and second arm portions 22. The second arm portions 22 are arranged at both ends of the second body 21. The first arm portions 12 and the second arm portions 22 are at least partially in contact and welded.
[0063] The first body 11 extends along the extension direction Y of the cross beam 51, and the first arm portions 12 extend along the length direction X of the vehicle towards the second mounting frame 2. The first arm portions 12 are arranged at both ends of the first body 11, making the first mounting frame 1 as a whole in a "U" shape. The second body 21 extends along the extension direction Y of the cross beam 51, and the second arm portions 22 extend along the length direction X of the vehicle towards the first mounting frame 1. The second arm portions 22 are arranged at both ends of the second body 21, making the second mounting frame 2 as a whole in a "U" shape. The first arm portions 12 and the second arm portions 22 are at least partially in contact and welded, making the first mounting frame 1 and the second mounting frame 2 firmly connected.
[0064] Among them, the first arm portions 12 can be located inside or outside the second arm portions 22. The first body 11, the first arm portions 12, the second body 21, the second arm portions 22 and the cross beam 51 enclose an installation space.
[0065] In addition, communication holes are provided on the first body 11 and the second body 21, and the Watt link 8 is rotatably connected to the mounting bracket through the connection holes.
[0066] More specifically, the first mounting frame 1 includes a first extension portion 13 connected to the first body 11. The extension direction of the first extension portion 13 is the same as the extension direction of the first body 11. The first extension portion 13 is welded to the side surface 512 of the beam 51, thereby increasing the contact area between the first mounting frame 1 and the beam 51 and improving the connection reliability between the first mounting frame 1 and the beam 51.
[0067] Similarly, the second mounting frame 2 includes a second extension portion 23 connected to the second body 21. The extension direction of the second extension portion 23 is the same as the extension direction of the second body 21. The second extension portion 23 is welded to the side surface 512 of the beam 51, thereby increasing the contact area between the second mounting frame 2 and the beam 51 and improving the connection reliability between the second mounting frame 2 and the beam 51.
[0068] The first extension portion 13 and the second extension portion 23 are respectively welded to two opposite side surfaces 512 of the beam 51 .
[0069] Further, such as Figure 3 As shown, the first mounting bracket 1 includes a first connecting portion 14 connected to the first arm portion 12 . The first connecting portion 14 is bent relative to the first arm portion 12 and connected to the top surface 511 of the beam 51 .
[0070] The first connection portion 14 is roughly parallel to the top surface 511 of the beam 51, so that the first connection portion 14 can fit the top surface 511 of the beam 51. Then the two can be connected by welding or screw connection, thereby further improving the connection reliability between the first mounting frame 1 and the beam 51.
[0071] Preferably, the first arm portion 12 provided with the first connecting portion 14 is arranged on a side close to the installation space relative to the second arm portion 22 .
[0072] Furthermore, Figure 2 and Figure 3 As shown, the two first arms 12 have different heights, the two second arms 22 have different heights, and the first arm 12 with a lower height is connected to the second arm 22 with a lower height, thereby forming an avoidance groove on one side of the mounting bracket along the extension direction Y of the crossbeam 51 to avoid the rotation of the Watt's link 8 relative to the mounting bracket, providing a larger movement space for the Watt's link 8.
[0073] Preferably, when the first connecting portion 14 is provided on only one first arm portion 12 , the first connecting portion 14 is provided on the first arm portion 12 with a lower height.
[0074] In another specific embodiment, Figure 4 and Figure 5As shown, the mounting bracket includes a third mounting bracket 3 and a fourth mounting bracket 4. A crossbeam 51 is provided on the floor 5. Along the longitudinal direction X of the vehicle, the third mounting bracket 3 and the fourth mounting bracket 4 are respectively connected to the crossbeam 51 from both sides thereof; an installation space is provided between the third mounting bracket 3, the fourth mounting bracket 4 and the crossbeam 51, and the Watt's connecting rod is installed in the installation space.
[0075] In this embodiment, if Figure 4 and Figure 5 As shown, the mounting bracket is configured as a separate third mounting bracket 3 and fourth mounting bracket 4. This facilitates production and processing of the mounting bracket, as well as the installation and fixation of the mounting bracket, Watt's linkage 8, and crossbeam 51. The third mounting bracket 3 and fourth mounting bracket 4 are connected to the crossbeam 51 from both sides along the longitudinal direction X of the vehicle, thereby increasing the contact area between the third mounting bracket 3 and fourth mounting bracket 4 and the crossbeam 51 and improving connection reliability.
[0076] Among them, the side of the installation space facing away from the crossbeam 51 is connected to the outside world, and the size of the installation space along the length direction X of the vehicle gradually decreases in the direction away from the crossbeam 51, so that the third mounting bracket 3 and the fourth mounting bracket 4 can limit the Watt's connecting rod 8 to prevent the Watt's connecting rod 8 from separating from the mounting bracket.
[0077] It is understandable that the mounting bracket may also be an integrated structure or the mounting bracket and the floor 5 may be integrally formed.
[0078] Specifically, such as Figure 5 As shown, the third mounting frame 3 has a third body 31, a third arm 32 and a second connecting portion 33. The third arm 32 is arranged at both ends of the third body 31. The second connecting portion 33 is connected to the third arm 32 and bent relative to the third arm 32. The second connecting portion 33 is connected to the top surface 511 of the beam 51.
[0079] The third body 31 extends along the extension direction Y of the crossbeam 51, and at least a portion of the third body 31 is bent toward the fourth mounting bracket 4 so that the distance between the third body 31 and the fourth mounting bracket 4 gradually decreases in the direction away from the crossbeam 51. The third arm portion 32 extends in a direction slightly inclined with respect to the longitudinal direction X of the vehicle. Two third arms 32 are provided, and each of the two third arms 32 is connected to a second connecting portion 33, and both second connecting portions 33 extend in a direction away from the third arm 32. The second connecting portion 33 is substantially parallel to the top surface 511 of the crossbeam 51, so that the second connecting portion 33 can be in contact with the top surface 511 of the crossbeam 51. The two can then be connected by welding or screwing, so that the third mounting bracket 3 is reliably connected to the crossbeam.
[0080] More specifically, Figure 5As shown, the fourth mounting frame 4 has a fourth body 41 and a third extension portion 43. The extension direction of the third extension portion 43 is the same as the extension direction of the third body 31. The third extension portion 43 is welded to the side surface 512 of the beam 51, so that the fourth mounting frame 4 is reliably connected to the beam 51.
[0081] Fourth mounting bracket 4 further includes a reinforcement plate 42, one end of which is connected to fourth body 41 and the other end to top surface 511 of crossbeam 51. At least a portion of the reinforcement plate is tilted relative to the plane perpendicular to the floor, creating a cavity between fourth body 41, reinforcement plate 42, and top surface 511 of crossbeam 51, thereby increasing the strength of the mounting bracket.
[0082] Furthermore, the two third arms 32 have different heights, and an avoidance groove is formed above the third arm 32 with the lower height to avoid the rotation of the Watt's link 8 relative to the mounting bracket, thereby providing a larger movement space for the Watt's link 8.
[0083] In addition, the third body 31 and the fourth body 41 are provided with connecting holes, and the Watt's link 8 is rotatably connected to the mounting bracket through the connecting holes.
[0084] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
