[0033] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0034] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0035] This embodiment provides a spring mounting device connected to the longitudinal beam 3 of the vehicle, such as Figure 1-Figure 6 As shown, it includes a first bracket assembly 1 and a second bracket 2 , the first bracket assembly 1 and the second bracket 2 are arranged opposite to each other, and the first bracket assembly 1 and the second bracket 2 are fixedly connected to the longitudinal beam 3 respectively.

[0036] In the embodiment of the utility model, the first bracket assembly 1 is connected to the longitudinal beam 3, which can provide a certain strength support for the longitudinal beam 3, and the second bracket 2 is also connected to the longitudinal beam 3, which also provides a certain strength support for the longitudinal beam 3. And the first bracket assembly 1 and the second bracket 2 are arranged relative to each other. It can be understood that the first bracket assembly 1 and the second bracket 2 arranged relative to each other provide stiffness support for each other, thereby improving the strength and stiffness of the spring installation device itself. At the same time, since the first bracket assembly 1 and the second bracket 2 are both connected to the longitudinal beam 3, it is equivalent to the first bracket assembly 1 and the second bracket 2 being indirectly connected through the longitudinal beam 3, while improving their own stiffness and strength, they also strengthen the stiffness and strength of the longitudinal beam 3. Compared with the prior art, the first bracket assembly 1 and the second bracket 2 arranged relative to each other and both connected to the longitudinal beam 3 improve the stiffness and strength of the spring installation device itself. Further, due to the improvement of their own stiffness and strength, the installation position of the spring installation device no longer needs to be set at a position with strong strength and stiffness on the longitudinal beam 3, but can be connected to any position of the longitudinal beam 3 according to actual conditions, which has the beneficial effect of simplifying the layout of the suspension assembly.

[0037] It should be noted that the longitudinal beam 3 may be a rod-shaped beam or a beam with a groove, and this embodiment does not impose any limitation on the specific shape of the longitudinal beam 3. Specifically, when the longitudinal beam 3 is a beam with a groove, the first bracket assembly 1 is arranged on the outer wall of the cavity surrounded by the groove, and the second bracket 2 is arranged on the inner wall of the cavity surrounded by the groove, and the first bracket assembly 1 and the second bracket 2 reinforce the rigidity and strength of the longitudinal beam 3 from both the inner and outer sides of the longitudinal beam 3.

[0038] In this embodiment, the cross section of the first bracket assembly 1 along the first section is U-shaped, a portion of the first bracket assembly 1 fits the profile of the longitudinal beam 3 , and the first section is perpendicular to the extension direction of the longitudinal beam 3 .

[0039] In the embodiment of the utility model, the configuration of the surface fit between the part of the first bracket assembly 1 and the longitudinal beam 3 can increase the contact area between the first bracket assembly 1 and the longitudinal beam 3, thereby enabling the first bracket assembly 1 to provide strength support for the longitudinal beam 3. Specifically, the first section is a section perpendicular to the extension direction of the longitudinal beam 3, and the section of the first bracket assembly 1 along the first section is U-shaped. It can be understood that compared with the first bracket assembly 1 of the planar structure in the prior art, the first bracket assembly 1 with a U-shaped section can wrap the longitudinal beam 3 from three intersecting directions, thereby improving the connection strength between the first bracket assembly 1 and the longitudinal beam 3. In addition, the first bracket assembly 1 with a U-shaped section also limits the longitudinal beam 3. When the longitudinal beam 3 is impacted by a force, the first bracket assembly 1 has a certain function of resisting the impact force to prevent the first bracket assembly 1 and the longitudinal beam 3 from separating.

[0040] In this embodiment, the first bracket assembly 1 includes a first connecting member 11 and a second connecting member 12, and the first connecting member 11 and the second connecting member 12 are respectively fixedly connected to the longitudinal beam 3, and part of the first connecting member 11 and the second connecting member 12 are arranged opposite to each other; the cross-section of the first connecting member 11 along the first section is L-shaped, and part of the first connecting member 11 and part of the second connecting member 12 are both in contact with the surface of the longitudinal beam 3.

[0041] In the embodiment of the utility model, the arrangement of the first connector 11 and the second connector 12 both fitting the profile of the longitudinal beam 3 can increase the contact area between the first connector 11 and the longitudinal beam 3, and between the second connector 12 and the longitudinal beam 3, so that the first connector 11 and the second connector 12 provide strength support for the longitudinal beam 3. Part of the first connector 11 and the second connector 12 are arranged relative to each other, and the first connector and the second bracket 2 arranged relatively provide rigidity support to each other, thereby improving the strength and rigidity of the first connection component itself. In addition, the first section is a section perpendicular to the extension direction of the longitudinal beam 3, and the section of the first connector 11 along the first section is L-shaped. It can be understood that compared with the first bracket assembly 1 of the prior art which is a planar structure, the first connector 11 with an L-shaped section can wrap the longitudinal beam 3 from two intersecting directions, thereby improving the connection strength between the first connector 11 and the longitudinal beam 3. In addition, the first connecting member 11 with an L-shaped cross section also limits the longitudinal beam 3. When the longitudinal beam 3 is impacted by a force, the first bracket assembly 1 has a certain function of resisting the impact force to prevent the first connecting member 11 and the longitudinal beam 3 from separating.

[0042] It should be noted that the first connecting member 11 and the second connecting member 12 may be a split structure connected to each other, or an integrated structure, and this embodiment does not impose any limitation on this.

[0043] In this embodiment, the first connecting member 11 includes a first connecting plate 111 and a second connecting plate 112 connected to each other; the first connecting plate 111 includes two first connecting parts 1111, a first reinforcing rib 1112 and a protrusion 1113, the first reinforcing rib 1112 is arranged in a direction perpendicular to the second connecting plate 112, the protrusion 1113 is arranged at one end of the first reinforcing rib 1112 away from the second connecting plate 112, the two first connecting parts 1111 are arranged on both sides of the first reinforcing rib 1112 and the protrusion 1113, the two first connecting parts 1111 are fixedly connected to the longitudinal beam 3, and the first reinforcing rib 1112 and the protrusion 1113 enclose the longitudinal beam 3 to form a first flow cavity.

The first connecting portion 1111 is provided to realize the connection between the first connecting member 11 and the longitudinal beam 3. Specifically, in practical applications, the first connecting portion 1111 is attached to the profile of the longitudinal beam 3, and the first connecting portion 1111 and the longitudinal beam 3 are welded. The first reinforcing rib 1112 is provided to improve the structural strength of the first connecting member 11. The first reinforcing rib 1112 is provided in a direction perpendicular to the bottom surface of the longitudinal beam 3. The protrusion 1113 is provided at the end of the first reinforcing rib 1112 away from the second connecting plate 112. The two first connecting parts 1111 sandwich the first reinforcing rib 1112 and the protrusion 1113 in the middle. The extension direction of the first connecting part 1111 is the same as the extension direction of the first reinforcing rib 1112. The end of the first reinforcing rib 1112 away from the protrusion 1113 is connected to the second connecting plate 112, and one end of the first connecting part 1111 is also connected to the second connecting plate 112. Furthermore, the first reinforcing rib 1112 and the protrusion 1113 are enclosed with the longitudinal beam 3 to form a first flow cavity. The first flow cavity is provided to provide space for fluid flow, which can realize functions such as leakage and exhaust, and improve the anti-corrosion performance.

[0045] It should be noted that in actual vehicle manufacturing, the longitudinal beam 3 and the spring mounting structure connected to the longitudinal beam 3 need to be immersed in the electrophoretic bath. After the immersion, part of the electrophoretic fluid may remain between the longitudinal beam 3 and the spring mounting structure connected to the longitudinal beam 3. The setting of the first flow chamber is used to provide a flow space for the electrophoretic fluid to flow out from between the longitudinal beam 3 and the spring mounting structure connected to the longitudinal beam 3.

[0046] It should also be noted that positioning holes are provided on the first connecting plate 111 and the second connecting plate 112 , and the positioning holes are used to position the first connecting plate 111 or the second connecting plate 112 before installation and connection.

[0047] In this embodiment, the second connecting plate 112 includes a planar portion 1121 and two second connecting portions 1122 that are connected to each other. The two second connecting portions 1122 are arranged on both sides of the planar portion 1121 along the extension direction of the longitudinal beam 3. The two second connecting portions 1122 protrude from the planar portion 1121 in a direction close to the longitudinal beam 3 and are fixedly connected to the longitudinal beam 3. There is a preset gap between the planar portion 1121 and the longitudinal beam 3; wherein the first flow cavity and the preset gap are connected.

[0048] In the embodiment of the utility model, the plane portion 1121 is provided for cooperating with the elastic component, and the connection portion is provided for realizing the connection between the second connection plate 112 and the longitudinal beam 3. Specifically, the two second connection portions 1122 are provided on both sides of the plane portion 1121 along the extension direction of the longitudinal beam 3, and the two second connection portions 1122 provided on both sides have the beneficial effect of improving the connection stability. The two second connection portions 1122 protrude from the plane portion 1121 in the direction close to the longitudinal beam 3 and are fixedly connected to the longitudinal beam 3. It can be understood that the second connection portion 1122 is connected to the longitudinal beam 3 and fits the profile of the longitudinal beam 3. There is a preset gap between the plane portion 1121 and the longitudinal beam 3, and the first flow cavity and the preset gap are connected. The setting of the preset gap is the same as the first flow cavity, which is used to provide a flow space for the electrophoretic liquid to flow out from the longitudinal beam 3 and the spring mounting structure connected to the longitudinal beam 3, which can realize the functions of leakage, exhaust, etc., and improve the anti-corrosion performance.

[0049] It should be noted that a positioning hole is also provided on the plane portion 1121 , and the positioning hole is used to position the second connecting plate 112 before the second connecting plate 112 is installed and connected.

[0050] It should also be noted that the second connecting portion 1122 can have two independent second connecting sub-portions, and the two second connecting sub-portions are arranged opposite to each other.

[0052] In the embodiment of the utility model, the first sinker 1123 is provided to cooperate with the elastic component.

The first sinker 1123 protrudes from the plane portion 1121 in the direction away from the first connecting plate 111, which facilitates the movable connection between the spring and the first sinker 1123, and has the beneficial effect of preventing the spring from being separated from the first sinker 1123 and causing failure. In addition, the first sinker 1123 is provided with a leakage hole 11231. In practical applications, the electrophoretic liquid can flow in the first flow cavity and the preset gap between the longitudinal beam 3 and the spring mounting structure connected to the longitudinal beam 3. When the electrophoretic liquid flows to the first sinker 1123, the electrophoretic liquid can flow out from the leakage hole 11231 between the longitudinal beam 3 and the spring mounting structure connected to the longitudinal beam 3, which has the beneficial effect of preventing the electrophoretic liquid from remaining between the longitudinal beam 3 and the spring mounting structure connected to the longitudinal beam 3.

Specifically, in practical applications, the first connecting portion 1111 is fitted to the profile of the longitudinal beam 3, and the third connecting portion 121 and the longitudinal beam 3 are welded. The second reinforcing rib 122 is used to improve the structural strength of the second connecting member 12.

The extension direction of the third connecting portion 121 is the same as the extension direction of the second reinforcing rib 122. The two third connecting portions 121 and the second reinforcing rib 122 are both connected to the first flange 123.

[0063] In the embodiment of the utility model, the longitudinal beam 3 is used to provide an installation position for the spring installation device. The suspension assembly having the spring installation device as described above, since the spring installation device has a first bracket assembly 1 and a second bracket 2 that are relatively arranged, it can be understood that the first bracket assembly 1 and the second bracket 2 that are relatively arranged provide rigidity support for each other, thereby improving the strength and rigidity of the spring installation device itself. At the same time, the first bracket assembly 1 and the second bracket 2 are both connected to the longitudinal beam 3, and the longitudinal beam 3 includes a second sinker 31 arranged on the bottom surface, and the second sinker 31 and the first bracket assembly 1 are fitted and fixedly connected. Compared with the prior art, the rigidity and strength of the longitudinal beam 3 are enhanced at the position connected to the longitudinal beam 3. Therefore, the position of the spring installation device no longer needs to be set at a position with strong strength and rigidity on the longitudinal beam 3, but can be connected to any position of the longitudinal beam 3 according to actual conditions, which has the beneficial effect of simplifying the layout of the suspension assembly.

[0064] In this embodiment, a vehicle is also proposed, comprising the suspension assembly as described above.

[0065] In the embodiment of the utility model, by providing the suspension assembly as described above, the layout of the suspension assembly can be simplified, thereby having the beneficial effect of reducing the complexity of the vehicle layout.
