[0028] Mounting bracket 2 is suitable for installation on the vehicle body 300. As some embodiments of this application, mounting bracket 2 and vehicle body 300 can be fixedly connected. For example, the connection method between mounting bracket 2 and vehicle body 300 can be, but is not limited to, welding connection, bolt connection, etc. As some embodiments of this application, mounting bracket 2 can be installed on vehicle body 300 by bolts.

[0029] The mounting bracket 2 defines a receiving space for accommodating the second connecting part 12. As some embodiments of this application, a portion of the structure of the second connecting part 12 is accommodated in the receiving space, or the entire structure of the second connecting part 12 is accommodated in the receiving space.

[0030] As some embodiments of this application, the mounting bracket 2 can be constructed as a sheet metal stamping part, which can improve the structural rigidity and strength of the mounting bracket 2, which is beneficial to improving the reliability of the mounting bracket 2 and improving the NVH (noise, vibration and acoustic roughness) performance of the vehicle.

[0031] The connector 3 passes through the mounting bracket 2 and the second connecting part 12 to movably connect the swing arm 1 to the mounting bracket 2. As some embodiments of this application, the mounting bracket 2 and the second connecting part 12 are respectively formed with mating holes adapted to the connector 3. The connector 3 passes through the mating holes of the mounting bracket 2 and the second connecting part 12 and is mated with a nut to movably connect the swing arm 1 to the mounting bracket 2.

[0032] As some embodiments of this application, the connector 3 may be constructed as a bolt, which passes through the mounting bracket 2 and the second connecting portion 12 and engages with a nut to enable the swing arm 1 to be movably connected to the mounting bracket 2.

[0033] It should be noted that this application, by providing the first connecting portion 11 and the second connecting portion 12 to the control arm 1, can connect the wheel assembly to the vehicle body 300, effectively absorbing road impacts and improving vehicle stability. Furthermore, the suspension assembly 100 of this application connects the control arm 1 to the vehicle body 300 via the mounting bracket 2. When a collision occurs and the control arm 1 or mounting bracket 2 is damaged, the control arm 1 and / or mounting bracket 2 can be directly replaced without replacing the undamaged vehicle body 300, thus reducing vehicle repair difficulty and cost.

In addition, the mounting bracket 2 of this application can be used for both front and rear suspensions, exhibiting high versatility, which helps improve the commonality rate of vehicle parts and reduces design and manufacturing costs while increasing assembly efficiency.

[0034] Therefore, the suspension assembly 100 of this application can connect the control arm 1 to the vehicle body 300 by setting the mounting bracket 2. When the control arm 1 and the mounting bracket 2 are damaged, they are easy to replace, the maintenance difficulty is low, the maintenance cost is low, and by setting the mounting bracket 2, there is no need to process a connection structure matching the control arm 1 on the vehicle body 300, and there is no need to make major modifications to the vehicle body 300, which helps to reduce production costs.

[0035] In some embodiments of this utility model, such as Figure 2 As shown, the mounting bracket 2 includes: two side plates 21 and a first connecting plate, the two side plates 21 being in a first direction (i.e., Figure 1 The two side plates 21 are positioned opposite each other and spaced apart in the X direction (as shown); the first connecting plate is located on the two side plates 21 along the second direction (i.e., Figure 1 One end of the first connecting plate (in the Y direction shown) is connected to two side plates 21. The first connecting plate and the two side plates 21 together define the receiving space. The second direction (i.e. Figure 1 The Y direction shown) and the first direction (i.e. Figure 1 Intersects in the X direction (as shown); Both side plates 21 have a first direction (i.e. Figure 1 The first mounting hole (shown in the X direction) is provided through the second connecting part 12, which is located between the two side plates 21 and has a second mounting hole. The connector 3 passes through the two first mounting holes and the second mounting hole.

[0036] The two side plates 21 in the first direction (i.e. Figure 1 They are arranged opposite and spaced apart in the X direction (as shown), in other words, along the first direction (i.e. Figure 1 As shown in the X direction), the two side plates 21 are directly opposite each other and spaced apart. As some embodiments of this application, along the first direction (i.e. Figure 1 (in the X direction shown), the distance between the two side plates 21 is greater than or equal to the length of the portion of the second connecting part 12 that is housed in the receiving space.

[0037] The first connecting plate is located on the two side plates 21 along the second direction (i.e. Figure 1 As shown in the Y direction, one end, as in some embodiments of this application, is along the second direction (i.e. Figure 1 (As shown in the Y direction), the first connecting plate is located at the same end of the two side plates 21.

[0038] A first connecting plate connects two side plates 21. The first connecting plate and the two side plates 21 together define a receiving space. As some embodiments of this application, along the first direction (i.e., Figure 1 (As shown in the X direction), the first connecting plate has two opposite ends, and the two ends of the first connecting plate are respectively connected to two side plates 21, and the first connecting plate and the two side plates 21 participate in defining the receiving space. As some embodiments of this application, the connection method of the first connecting plate and the two side plates 21 can be, but is not limited to, welding connection, snap connection, bolt connection, etc., or the first connecting plate and the two side plates 21 can be integrally formed. For example, the first connecting plate and the two side plates 21 can be constructed as an integral sheet metal stamping part.

[0039] The second direction (i.e.) Figure 1 The Y direction shown) and the first direction (i.e. Figure 1The second direction (i.e., the X direction shown) intersects with the X direction. As some embodiments of this application, the second direction (i.e., the X direction shown) intersects with the X direction. Figure 1 The Y direction shown can be perpendicular to the first direction (i.e., Figure 1 (The X direction is shown).

[0040] Both side plates 21 have a first direction (i.e. Figure 1 As shown in the X direction, a first mounting hole is provided through the hole. As some embodiments of this application, along the first direction (i.e., Figure 1 (As shown in the X direction), both side plates 21 have a through-hole first mounting hole, and at least part of the first mounting holes on the two side plates 21 correspond to each other. For example, the first mounting holes on the two side plates 21 are directly opposite each other, or the first mounting holes on the two side plates 21 are partially misaligned. The partial misalignment of the first mounting holes on the two side plates 21 can be understood as, along the first direction (i.e., Figure 1 (As shown in the X direction), the orthographic projections of the first mounting holes on the two side plates 21 coincide. The first mounting hole is the mating hole on the mounting bracket 2 mentioned above that is adapted to the connector 3.

[0041] The second connecting portion 12 is located between the two side plates 21 and has a second mounting hole. As some embodiments of this application, along the first direction (i.e., Figure 1 (As shown in the X direction), the second mounting hole can be constructed as a through hole on the second connecting part 12, and the second mounting hole corresponds to the first mounting hole.

[0042] The connector 3 passes through two first mounting holes and a second mounting hole. As some embodiments of this application, it extends along the first direction (i.e., Figure 1 (As shown in the X direction), the connector 3 is sequentially inserted through one of the first mounting holes, the second mounting hole, and the other first mounting hole. As some embodiments of this application, the connector 3 can be constructed as a bolt, which is inserted through the two first mounting holes and the second mounting hole and engages with a nut to allow the second connecting part 12 to be movably connected to the mounting bracket 2.

[0043] By making the two side plates 21 in the first direction (i.e. Figure 1 The two side plates 21 are arranged opposite each other and spaced apart in the X direction (as shown), and the first connecting plate is located on the two side plates 21 along the second direction (i.e. Figure 1 One end of the mounting bracket 2 (in the Y direction shown) is connected to two side plates 21, which can define a receiving space to facilitate the reception of the second connecting part 12. At the same time, it can make the structure of the mounting bracket 2 reasonable, and can make the mounting bracket 2 have high structural strength and rigidity. Furthermore, by making both side plates 21 have a direction along the first direction (i.e., Figure 1 The first mounting hole (shown in the X direction) is provided through the second connecting part 12, which is located between the two side plates 21 and has a second mounting hole. This facilitates the assembly of the second connecting part 12, the mounting bracket 2, and the connector 3, and helps to reduce the assembly difficulty.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, at least one side plate 21 has a limiting protrusion 212 on its surface opposite to the receiving space. The limiting protrusion 212 extends circumferentially along the first mounting hole, which is an elongated hole extending along a third direction. The third direction is perpendicular to the first direction (i.e., Figure 1 Intersects in the X direction (as shown); Among them, the connector 3 is an eccentric connector, and is configured such that during the rotation of the eccentric connector, the eccentric connector is adapted to move along a third direction under the stop action of the limiting protrusion 212.

[0045] At least one side plate 21 has a limiting protrusion 212 on the surface away from the receiving space. As some embodiments of this application, one side plate 21 has a limiting protrusion 212 on the surface away from the receiving space, or both side plates 21 have a limiting protrusion 212 on the surface away from the receiving space.

[0046] The limiting protrusion 212 extends circumferentially along the first mounting hole. As some embodiments of this application, the limiting protrusion 212 is constructed as a U-shaped protrusion extending circumferentially along the first mounting hole.

[0047] The first mounting hole is an elongated hole extending along a third direction, and the third direction is perpendicular to the first direction (i.e., Figure 1 As some embodiments of this application, the third direction can be configured to intersect with the second direction (i.e., the X direction shown). Figure 1 The direction shown is the same as the Y direction, or the third direction can be constructed to be the same as the second direction (i.e., the Y direction). Figure 1 The third direction can be perpendicular to the first direction (i.e., the Y direction shown). As some embodiments of this application, the third direction can be perpendicular to the first direction (i.e., the Y direction shown). Figure 1 (The X direction is shown).

[0048] The connector 3 is an eccentric connector, and its structure is such that during the rotation of the eccentric connector, the eccentric connector is adapted to move along a third direction under the stop action of the limiting protrusion 212. It can be understood that when the eccentric connector is rotated, the eccentric connector and the limiting protrusion 212 stop each other, which enables the eccentric connector to move in the first mounting hole along a third direction to adjust the position of the eccentric connector, thereby facilitating the adjustment of the outward tilt angle of the swing arm 1 and other parameters of the swing arm 1, which helps to reduce the difficulty of adjustment.

[0049] By having a limiting protrusion 212 on the surface of at least one side plate 21 facing away from the receiving space, and by making the connector 3 an eccentric connector, it is easy to adjust the position of the eccentric connector, thereby enabling the adjustment of the outward tilt angle of the swing arm 1 and other parameters of the swing arm 1, which helps to reduce the difficulty of adjustment. At the same time, the limiting protrusion 212 and the first mounting hole can limit the range of movement of the eccentric connector and reduce the risk of over-adjustment.

[0050] In some embodiments of this utility model, the third direction and the second direction (i.e. Figure 1 The Y direction shown is the same as the second direction (i.e., the third direction is the same as the second direction). Figure 1 Intersects with the Y direction shown.

[0051] This configuration allows for setting the extension direction of the first mounting hole according to actual needs, so that the movement of the eccentric connector can reasonably adjust the camber angle of the swing arm 1 and other parameters of the swing arm 1, which is beneficial to improving the performance of the suspension assembly 100.

[0052] In some embodiments of this utility model, such as Figure 2 As shown, the eccentric connector includes: a first connecting body 31 and a gasket. The first connecting body 31 passes through the first mounting hole and the second mounting hole. The gasket is connected to the first connecting body 31. The central axis of the first connecting body 31 is parallel to and spaced apart from the central axis of the gasket. During the rotation of the first connecting body 31, the gasket is adapted to drive the first connecting body 31 to move in a third direction under the stop action of the limiting protrusion 212.

[0053] The gasket is connected to the first connecting body 31. As some embodiments of this application, the connection method between the gasket and the first connecting body 31 can be, but is not limited to, welding or integral molding.

[0054] The central axis of the first connecting body 31 is parallel to and spaced apart from the central axis of the gasket. In other words, the central axis of the first connecting body 31 does not coincide with and is parallel to the central axis of the gasket.

[0055] During the rotation of the first connecting body 31, the shim is adapted to drive the first connecting body 31 to move in the first mounting hole along a third direction under the stop action of the limiting protrusion 212, so as to adjust the position of the eccentric connector and adjust the swing arm 1.

[0056] This arrangement allows the eccentric connector to move along a third direction within the first mounting hole during the tightening process, thanks to the stop provided by the shim and the limiting protrusion 212. This facilitates the adjustment of the position of the eccentric connector to adjust the rocker arm 1, making it easier to adjust the outward tilt angle and other parameters of the rocker arm 1, thus reducing the difficulty of adjustment.

[0057] In some embodiments of this utility model, the first connecting body 31 includes a screw 311 and a screw head 312. The screw head 312 is connected to one end of the screw 311, and a washer is connected to the end of the screw head 312 near the screw 311.

[0058] The screw head 312 is connected to one end of the screw rod 311. As some embodiments of this application, the connection method between the screw head 312 and the screw rod 311 can be, but is not limited to, welding connection or integral molding.

[0059] The washer is connected to the end of the screw head 312 near the screw rod 311. In some embodiments of this application, the outer contour of the washer can be constructed as the outer contour of a cam. The washer is sleeved on the screw rod 311, and the washer is connected to the end of the screw head 312 near the screw rod 311. In some embodiments of this application, the connection method between the washer and the screw head 312 can be, but is not limited to, welding or integral molding. This arrangement makes the structure of the eccentric connector reasonable, facilitates processing, and ensures reliable abutment between the washer and the limiting protrusion 212.

[0060] In some embodiments of this utility model, the first mounting hole is an oblong hole.

[0061] As some embodiments of this application, the first mounting hole includes semi-circular portions at both ends and a rectangular portion connecting the two semi-circular portions. The diameter of the semi-circular portion can be adapted to the diameter of the screw 311, the length of the rectangular portion can be set according to actual needs, and the width of the rectangular portion can be adapted to the diameter of the screw 311.

[0062] By making the first mounting hole an oblong hole, it is easier to machine the first mounting hole on the side plate 21, which helps to reduce the machining difficulty. In addition, the semi-circular parts at both ends of the oblong hole can be adapted to the cross section of the screw 311, which can provide adjustment margin for the installation position of the connector 3 and facilitate adjustment.

[0063] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the mounting bracket 2 also includes a second connecting plate 23, which connects the two side plates 21. The second connecting plate 23 and the first connecting plate are respectively connected to different sides of the two side plates 21, and the two are connected at an angle.

[0064] The second connecting plate 23 connects the two side plates 21. As some embodiments of this application, along the first direction (i.e. Figure 1 (in the X direction shown) The second connecting plate 23 has two opposite ends, and the two ends of the second connecting plate 23 are respectively connected to two side plates 21. As some embodiments of this application, the connection method between the second connecting plate 23 and the two side plates 21 can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc., or the second connecting plate 23 and the two side plates 21 can be integrally formed.

[0065] The second connecting plate 23 and the first connecting plate are respectively connected to different sides of the two side plates 21, and the two are connected at an angle. As some embodiments of this application, the included angle between the second connecting plate 23 and the first connecting plate can be, but is not limited to, 90 degrees, 120 degrees, 150 degrees, etc. The connection method between the second connecting plate 23 and the first connecting plate can be, but is not limited to, welding connection, snap connection, bolt connection, etc., or the second connecting plate 23 and the first connecting plate can be integrally formed.

[0066] As some embodiments of this application, the first connecting plate, the second connecting plate 23, and the two side plates 21 can be integrally formed by stamping.

[0067] By including a second connecting plate 23 in the mounting bracket 2, and connecting the two side plates 21, the structure of the mounting bracket 2 can be made reasonable, and the mounting bracket 2 can have high structural strength and rigidity, which is conducive to improving the reliability of the mounting bracket 2.

[0068] In some embodiments of this utility model, the side of the second connecting plate 23 away from the first connecting plate has a clearance portion for avoiding the second connecting portion 12. As some embodiments of this application, the clearance portion can be constructed as a clearance notch. By having a clearance portion on the side of the second connecting plate 23 away from the first connecting plate, the second connecting portion 12 can be avoided by the clearance portion, reducing the risk of interference between the second connecting portion 12 and the second connecting plate 23, increasing the range of motion of the second connecting portion 12, and allowing the mounting bracket 2 to be adapted to second connecting portions 12 of different sizes, which is beneficial to improving the versatility of the mounting bracket 2.

[0069] In some embodiments of this utility model, the second connecting plate 23 is in the second direction (i.e. Figure 1 The dimension in the Y direction (as shown) is smaller than that of the side plate 21 in the second direction (i.e. Figure 1 The dimensions in the Y direction (as shown) are adjusted to avoid the second connecting part 12. This arrangement avoids the second connecting part 12, reduces the risk of interference between the second connecting part 12 and the second connecting plate 23, increases the range of motion of the second connecting part 12, and allows the mounting bracket 2 to be adapted to second connecting parts 12 of different sizes, which is beneficial to improving the versatility of the mounting bracket 2.
