[0038] Combine the following Figure 1-Figure 10 A suspension assembly 10 and a vehicle having the same according to an embodiment of the present invention will be described in detail.

[0039] Reference Figure 1-Figure 4 As shown, the suspension assembly 10 according to the embodiment of the utility model includes: a frame 1, a bushing assembly 2 and an anti-collision assembly 3, the frame 1 includes a mounting portion 11 and a connecting portion 12 fixedly connected, the mounting portion 11 has a mounting hole 111, the connecting portion 12 is suitable for being connected to the powertrain of the vehicle, the bushing assembly 2 is passed through and fixed in the mounting hole 111, the bushing assembly 2 is suitable for being connected to the body of the vehicle, wherein the powertrain can be connected to the connecting portion 12 by fasteners, and the bushing assembly 2 can be connected to the body by fasteners, so as to realize that the powertrain is connected to the body through the suspension assembly 10.

[0040] Reference Figure 1 and Figure 2As shown, the anti-collision component 3 includes a first anti-collision pad 31, a second anti-collision pad 32 and an anti-collision connector 33. The first anti-collision pad 31 and the second anti-collision pad 32 are both detachably connected to the connecting portion 12, and the anti-collision connector 33 is detachably connected to the mounting portion 11. The anti-collision component 3 can be connected to the skeleton 1 at multiple positions of the skeleton 1, which is beneficial to improving the stability and reliability of the connection between the anti-collision component 3 and the skeleton 1, and preventing the anti-collision component 3 from loosening, rotating, and falling off during the assembly or transportation of the suspension assembly 10. In the axial direction of the mounting hole 111, the first anti-collision pad 31 is fitted with one end of the mounting portion 11, and the second anti-collision pad 32 is fitted with the other end of the mounting portion 11. The anti-collision connector 33 is connected between the first anti-collision pad 31 and the second anti-collision pad 32. The crash pad 32 can protect the skeleton 1 in the axial direction of the mounting hole 111. When the impact and load of the powertrain on the skeleton 1 are large and cause the skeleton 1 to move in the axial direction of the mounting hole 111, the mounting portion 11 can be stopped on the vehicle body by the first crash pad 31 or the second crash pad 32. The first crash pad 31 and the second crash pad 32 can buffer the collision between the mounting portion 11 and the vehicle body. At the same time, by limiting the first crash pad 31 and the second crash pad 32 by the vehicle body, the displacement of the mounting portion 11 in the axial direction of the mounting hole 111 can be limited to reduce the displacement of the skeleton 1 in the axial direction of the mounting hole 111, thereby reducing the displacement of the powertrain in the axial direction of the mounting hole 111 and avoiding interference between the skeleton 1 and the powertrain and other components in the vehicle.

[0041] It should be noted that the vehicle body has a mounting seat for connecting to the shaft sleeve assembly 2, and the mounting seat includes a first mounting plate and a second mounting plate. In the axial direction of the mounting hole 111, the first mounting plate and the second mounting plate are arranged relatively spaced apart, and the shaft sleeve assembly 2 is installed between the first mounting plate and the second mounting plate. The fasteners pass through the first mounting plate, the shaft sleeve assembly 2 and the second mounting plate to connect the shaft sleeve assembly 2 to the vehicle body. In the axial direction of the mounting hole 111, the first anti-collision pad 31 is located between the first mounting plate and the mounting portion 11, and the second anti-collision pad 32 is located between the second mounting plate and the mounting portion 11. When the vehicle is at rest, there may be a gap between the first anti-collision pad 31 and the first mounting plate, and there may be a gap between the second anti-collision pad 32 and the second mounting plate. When the powertrain is working and acts on the impact of the skeleton 1 When the load is large and causes the skeleton 1 to move along the axial direction of the mounting hole 111, if the mounting portion 11 moves toward the first mounting plate, the mounting portion 11 can be stopped on the first mounting plate by the first anti-collision pad 31, and if the mounting portion 11 moves toward the second mounting plate, the mounting portion 11 can be stopped on the second mounting plate by the second anti-collision pad 32. That is to say, in the axial direction of the mounting hole 111, the first mounting plate and the second mounting plate can rigidly limit the maximum displacement of the mounting portion 11 on both sides of the mounting portion 11. At the same time, the two ends of the mounting portion 11 are respectively fitted with the first anti-collision pad 31 and the second anti-collision pad 32. The first anti-collision pad 31 and the second anti-collision pad 32 can play a role of shock absorption and buffering, thereby reducing the damage caused by the collision between the skeleton 1 and the vehicle body, thereby helping to improve the service life of the suspension assembly 10.

[0042] According to the suspension assembly 10 of the embodiment of the utility model, in the axial direction of the mounting hole 111, the first anti-collision pad 31 is fitted with one end of the mounting portion 11, and the second anti-collision pad 32 is fitted with the other end of the mounting portion 11, so as to increase the limiting ability of the suspension assembly 10 in the axial direction of the mounting hole 111, which can reduce the axial displacement of the skeleton 1 and the powertrain along the mounting hole 111, and avoid interference between the suspension assembly 10 and the powertrain and other components in the vehicle.

[0043] In some embodiments of the utility model, the disassembly and assembly direction of the first anti-collision pad 31 and the connecting part 12 is a first direction, the disassembly and assembly direction of the second anti-collision pad 32 and the connecting part 12 is a second direction, and the disassembly and assembly direction of the anti-collision connector 33 and the mounting part 11 is a third direction. At least two of the first direction, the second direction and the third direction are different. When the anti-collision component 3 is subjected to external force in any direction, the disassembly and assembly direction of at least one of the first anti-collision pad 31, the second anti-collision pad 32 and the connecting part 12 is different from the force direction, and the anti-collision connector 33 connects the first anti-collision pad 31 and the second anti-collision pad 32 into one to prevent the anti-collision component 3 from loosening, rotating or falling off, thereby further improving the stability and reliability of the connection between the anti-collision component 3 and the skeleton 1.

[0044] In some embodiments of the present invention, the first direction and the second direction are both perpendicular to the third direction, so as to further improve the stability and reliability of the connection between the anti-collision component 3 and the frame 1 and reduce the risk of the anti-collision component 3 falling off.

[0045] Reference Figure 1 and Figure 2 As shown, the first direction is the left-right direction, the second direction is the right-left direction, and the third direction is the bottom-up direction, wherein the direction in which the first anti-collision pad 31 is installed to the connecting portion 12 is the positive direction of the first direction (rightward), and the direction in which the first anti-collision pad 31 is removed from the connecting portion 12 is the negative direction of the first direction (leftward), the direction in which the second anti-collision pad 32 is installed to the connecting portion 12 is the positive direction of the second direction (leftward), and the direction in which the second anti-collision pad 32 is removed from the connecting portion 12 is the negative direction of the second direction (rightward), the direction in which the anti-collision connector 33 is installed to the mounting portion 11 is the positive direction of the third direction (upward), and the direction in which the anti-collision connector 33 is removed from the mounting portion 11 is the negative direction of the third direction (downward), that is, the installation directions of the first anti-collision pad 31, the second anti-collision pad 32 and the anti-collision connector 33 are all different, and the disassembly directions of the first anti-collision pad 31, the second anti-collision pad 32 and the anti-collision connector 33 are also all different.

[0046] When the anti-collision component 3 is subjected to an external force in any direction, the disassembly direction of at least one of the first anti-collision pad 31, the second anti-collision pad 32 and the connecting portion 12 is different from the force direction, which can prevent the anti-collision component 3 from loosening, rotating or falling off. For example, when the anti-collision component 3 is subjected to an external force in the negative direction of the third direction (the disassembly direction of the anti-collision connector 33), since the disassembly directions of the first anti-collision pad 31 and the second anti-collision pad 32 are different from the disassembly direction of the anti-collision connector 33, the first anti-collision pad 31 and the second anti-collision pad 32 can remain stably connected to the connecting portion 12 and prevent the anti-collision connector 33 from being removed from the mounting portion 11, thereby preventing the anti-collision component 3 from loosening, rotating or falling off. When the anti-collision component 3 is subjected to an external force in the first direction or the second direction, the process is similar to the above process and will not be repeated here.

The mounting ring 331 may include a connected snap-in insert 3311 and a snap-in notch 3312 , and the mounting protrusion 112 of the frame 1 is suitable for passing through the snap-in notch 3312 and fitting with the snap-in insert 3311 .

[0065] In some embodiments of the present invention, the powertrain includes a motor, and the connecting portion 12 of the frame 1 is provided with at least one powertrain connection hole 123, and a fastener can be inserted into the powertrain connection hole 123 and cooperate with the motor in the powertrain to fix the motor to the frame 1. The fastener can be a screw, a pin, etc.

[0066] In some embodiments of the present invention, the frame 1 can be made of aluminum alloy, sheet metal, ductile iron or engineering plastic, so that the frame 1 has higher strength and can withstand greater impact and load.

[0067] In the relevant technology, the peak torque of the driving motor of the powertrain is large, and it converts rapidly in a certain speed range. The torque will reverse from positive to negative in a very short time, causing the suspension to bear large and rapidly changing impacts and loads. At present, the suspension only has X-direction or Z-direction limit, and the Y-direction limit capability is relatively weak. The suspension cannot take into account the adjustment of the stiffness ratio in all directions, and cannot effectively absorb large impacts and loads, resulting in a large displacement offset of the suspension and the powertrain, which can easily cause interference between the suspension and the powertrain and the surrounding matching components.

[0068] According to the suspension assembly 10 of the embodiment of the utility model, the first anti-collision pad 31 is fitted with one end of the mounting portion 11, and the second anti-collision pad 32 is fitted with the other end of the mounting portion 11, so as to increase the limiting capacity of the suspension assembly 10 in the axial direction of the mounting hole 111 (the Y direction of the vehicle), so that the suspension assembly 10 can take into account the proportional adjustment of the stiffness in all directions, and the anti-collision component 3 can effectively absorb large impacts and loads, reasonably control the displacement of the powertrain, prevent the suspension assembly 10 and the powertrain from interfering with the surrounding matching parts, and effectively ensure the assembly posture and function of the suspension assembly 10. When assembling the suspension assembly 10, the sleeve assembly 2 can be firstly interference-fitted to the mounting hole 111 of the frame 1, and then the anti-collision component 3 can be interference-fitted to the frame 1. The suspension assembly 10 has a simple structure and is easy to assemble.

[0069] A vehicle according to another embodiment of the present invention includes the suspension assembly 10 of the above embodiment.

[0070] According to the vehicle of the embodiment of the utility model, in the axial direction of the mounting hole 111, the first anti-collision pad 31 is fitted with one end of the mounting portion 11, and the second anti-collision pad 32 is fitted with the other end of the mounting portion 11, so as to increase the limiting ability of the suspension assembly 10 in the axial direction of the mounting hole 111, and reduce the axial displacement of the skeleton 1 and the powertrain along the mounting hole 111, so as to avoid interference between the suspension assembly 10 and the powertrain and other components in the vehicle.
