[0033] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0034] Next, refer to the attached Figures 1-5 Describe the suspension assembly 100 according to the embodiments of the present invention.

[0035] Refer to Figure 1 , Figure 2 and Figure 3, The suspension assembly 100 according to an embodiment of the present utility model includes: a subframe 70, a power assembly 80, a first suspension bracket 10, a first fastener 20, and a second fastener 30.

[0036] Specifically, the front end of the first suspension bracket 10 (such as Figure 1 the front end of the first suspension bracket 10 shown) is connected to the subframe 70. The first suspension bracket 10 is provided with a first fixing hole 11 and a second fixing hole 12 arranged at intervals. The second fixing hole 12 is an elongated hole extending in an oblique direction from the front upper to the rear lower (such as Figure 1 the front-rear direction shown); the first suspension bracket 10 is connected to the power assembly 80 through the first fastener 20 passing through the first fixing hole 11. The first fastener 20 is configured to break when the force applied is greater than or equal to the force limit value; the first suspension bracket 10 is connected to the power assembly 80 through the second fastener 30 passing through the second fixing hole 12.

[0037] It should be noted that the force limit value is the maximum shear stress that the first fastener 20 can withstand. When the force on the first fastener 20 reaches the force limit value, the first fastener 20 breaks.

[0038] For example, as Figure 1 , Figure 2 and Figure 3 shown, the front end of the first suspension bracket 10 is connected to the subframe 70, the rear end of the first suspension bracket 10 is connected to the front end of the power assembly 80. The first suspension bracket 10 is provided with a first fixing hole 11 and a second fixing hole 12. The first fixing hole 11 is a circular hole, and the first fixing hole 11 penetrates the first suspension bracket 10 along the thickness direction of the first suspension bracket 10. The first fastener 20 passes through the first fixing hole 11 to fixedly connect the power assembly 80 and the subframe 70. The second fixing hole 12 is an elongated hole extending in the front-rear direction, and the second fixing hole 12 penetrates the first bracket along the thickness direction of the first suspension bracket 10. The second fastener 30 passes through the second fixing hole 12 to connect the power assembly 80 and the subframe 70. Preferably, the second fastener 30 is a bolt, and the bolt has a low cost and is convenient for batch use.

[0039] During the driving of the vehicle, when the vehicle collides, the deformation of the subframe 70 drives the power assembly 80 to move towards the vehicle front bulkhead. When the impact force reaches the preset value of the first fastener 20, the first fastener 20 breaks, and the power assembly 80 is only connected to the subframe 70 by the second fastener 30. At this time, the power assembly 80 can move relative to the subframe 70 in the second fixing hole 12, so that the impact force suffered by the subframe 70 transmitted to the power assembly 80 can be reduced, and further the impact of the power assembly 80 on the front bulkhead, which affects the safety of the occupants in the passenger compartment, can be reduced.

[0040] The suspension assembly 100 of the present utility model is provided with a first fixing hole 11 and a second fixing hole 12 on the first suspension bracket 10. When the force on the first fastener 20 reaches a preset value, the power assembly 80 can move within the second fixing hole 12, thereby disconnecting the force transmission path for the subframe 70 to transmit impact force, and further preventing the power assembly 80 from moving backward and hitting the front bulkhead. Therefore, the safety of the occupants in the passenger compartment can be protected, and the vehicle safety performance can be improved. At the same time, the second fixing hole 12 increases the crush stroke for the power assembly 80 and provides a moving space for the power assembly 80, thereby reducing the intrusion of the power assembly 80 into the passenger compartment and further improving the vehicle safety performance.

[0041] For the suspension assembly 100 according to an embodiment of the present utility model, the first fixing hole 11 and the second fixing hole 12 are provided on the first suspension bracket 10, which can disconnect the force transmission path for the subframe 70 to transmit impact force to the power assembly 80 within a certain stroke, thereby protecting the safety of the occupants in the passenger compartment and improving the vehicle safety performance. At the same time, the crush stroke for the power assembly 80 can be increased, and the intrusion of the power assembly 80 into the passenger compartment can be reduced.

[0042] According to some embodiments of the present utility model, referring to Figure 1 , in the vehicle's front-to-back direction, the second fixing hole 12 extends obliquely downward. Thus, by defining the direction of the second fixing hole 12, the direction of the power assembly 80 moving towards the front bulkhead can be adjusted. When the vehicle is impacted, the power assembly 80 can be made to avoid the front bulkhead, thereby effectively preventing the power assembly 80 from intruding into the front bulkhead.

[0043] For example, as Figure 1 shown, the second fixing hole 12 extends in the direction from front upper to rear lower. When the subframe 70 drives the power assembly 80 to move, the power assembly 80 moves in the rear lower direction along the second fixing hole 12, and further effectively prevents the power assembly 80 from hitting the front bulkhead.

[0044] According to some embodiments of the present utility model, referring to Figure 1 and Figure 3 , the first fastener 20 breaks, and the second fastener 30 slides in the second fixing hole 12 in the front-rear direction. Thus, the power assembly 100 can slide along the extension direction of the second fixing hole 12, thereby avoiding the power assembly 100 directly hitting the passenger compartment.

[0045] According to some embodiments of the present utility model, referring to Figure 1 and Figure 3, the number of the second fixing holes 12 is multiple, that is to say, the number of the second fixing holes 12 can be two, three or four or more, the number of the second fasteners 30 is multiple, that is to say, the number of the second fasteners 30 can be two, three or four or more, and the number of the second fixing holes 12 corresponds to the number of the second fasteners 30 one by one.

[0046] In this way, setting multiple second fixing holes 12 and multiple second fasteners 30 can ensure the connection strength between the power assembly 80 and the subframe 70, thereby effectively avoiding the separation of the power assembly 80 and the subframe 70. At the same time, the number of the second fixing holes 12 corresponds to the number of the second fasteners 30, and this setting of the number is reasonable, without the need to check again whether the second fasteners 30 are installed in the second fixing holes 12.

[0047] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 , a first bushing 13 is provided at the front end of the first mounting bracket 10, and the first mounting bracket 10 is rotatably connected to the subframe 70 through the first bushing 13. Thus, the first bushing 13 is connected to the subframe 70, which can facilitate the connection between the first mounting bracket 10 and the subframe 70. At the same time, the first bushing 13 can rotate relative to the subframe 70. When the subframe 70 is impacted, the first bushing 13 rotates relative to the subframe 70, thereby adjusting the movement direction of the power assembly 80, and further avoiding the power assembly 80 from invading the front bulkhead.

[0048] According to some alternative embodiments of the present invention, referring to Figure 1 and Figure 3 , the first mounting bracket 10 is provided with a mounting hole, and the first bushing 13 includes: an outer tube 131, a support body 132 and a rubber main body 133. The outer tube 131 is fixed in the mounting hole; the support body 132 is arranged in the outer tube 131, a connection hole 1321 is provided on the support body 132, and the support body 132 is connected to the subframe 70 through a third fastener 40 passing through the connection hole 1321; the rubber main body 133 is connected between the outer tube 131 and the support body 132.

[0049] In this way, the mounting hole provides an installation position for the first bushing 13, which can facilitate the arrangement of the first bushing 13. The outer tube 131 and the support body 132 cooperate to form an installation space for the rubber main body 133, which can facilitate the setting of the rubber main body 133. At the same time, the rubber main body 133 has elasticity, which can relieve the vibration of the power assembly 80. The support body 132 can support the structure of the first bushing 13, which can effectively prevent the first bushing 13 from deforming under force, and further effectively prevent the first bushing 13 from being damaged. In addition, the structure of the third fastener 40 connecting the first mounting bracket 10 and the subframe 70 is simple and the installation is convenient, which can improve the assembly efficiency.

[0050] For example, as Figure 1 and Figure 3 shown, the front end of the first mounting bracket 10 is provided with a mounting hole. The outer tube 131 is in a hollow cylindrical shape and is disposed in the mounting hole. The support body 132 is disposed inside the outer tube 131, and the rubber main body 133 is filled between the support body 132 and the outer tube 131. Preferably, the outer tube 131, the support body 132, and the rubber main body 133 are vulcanized and connected, which can ensure the strength of the first bushing 13 and avoid damage to the first bushing 13. The third fastener 40 is a bolt, and the bolt has a low cost and is convenient for batch use.

[0051] According to some embodiments of the present invention, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the number of the first mounting brackets 10 is multiple. That is to say, the number of the first mounting brackets 10 can be two, three, four or more. The multiple first mounting brackets 10 are arranged on both sides of the powertrain 80 in the left - right direction of the vehicle (such as the left - right direction shown in Figure 1 ).

[0052] In this way, the multiple first mounting brackets 10 can ensure the connection strength between the powertrain 80 and the subframe 70, thereby effectively preventing the separation of the powertrain 80 from the subframe 70. At the same time, the first mounting brackets 10 are arranged on both sides of the powertrain 80, which can make both sides of the powertrain 80 evenly stressed, thereby further preventing the separation of the powertrain 80 from the subframe 70.

[0053] Furthermore, two first mounting brackets 10 are provided, and the two first mounting brackets 10 are respectively arranged on the left and right sides of the powertrain 80. Thereby, both sides of the powertrain 80 can be evenly stressed, effectively preventing the separation of the powertrain 80 from the subframe 70.

[0054] For example, as Figure 3 and Figure 4 shown, the left - hand first mounting bracket 10 is provided with one first fixing hole 11 and three second fixing holes 12, and the right - hand first mounting bracket 10 is provided with one first fixing hole 11 and two second fixing holes 12.

[0055] According to some embodiments of the present invention, referring to Figure 1 , Figure 2 and Figure 5 , the mounting assembly 100 includes: a second mounting bracket 50, the second mounting bracket 50 is connected to the rear side of the powertrain 80 (such as the rear side of the powertrain 80 shown in Figure 2 ), and the front end of the second mounting bracket 50 (such as Figure 2The front end of the second suspension bracket 50 shown is connected to the powertrain 80, and the rear end of the second suspension bracket 50 (such as Figure 2 the rear end of the second suspension bracket 50 shown) is connected to the subframe 70.

[0056] In this way, the second suspension bracket 50 cooperates with the first suspension bracket 10 to firmly fix the powertrain 80 to the subframe 70, thereby effectively preventing the separation of the powertrain 80 from the subframe 70. At the same time, the second suspension bracket 50 and the first suspension bracket 10 are separated and arranged. This structural arrangement is reasonable, convenient for layout, and can also ensure the strength of fixing the powertrain 80 by the second suspension bracket 50 and the first suspension bracket 10 on the subframe 70.

[0057] For example, as Figure 1 、 Figure 2 and Figure 5 shown, the second suspension bracket 50 extends in the front-rear direction. The front end of the second suspension bracket 50 is connected to the powertrain 80, and the rear end of the second suspension bracket 50 is connected to the subframe 70.

[0058] When the first fastener 20 of the first suspension bracket 10 breaks due to the applied force reaching the limit value, the powertrain 80 slides along the second fixing hole 12 of the first suspension bracket 10. At the same time, the powertrain 80 rotates around the connection shaft between the second suspension bracket 50 and the subframe, and the attitude changes to be higher at the front and lower at the rear, so that the powertrain 80 avoids the foot area of the front-row passengers on the front bulkhead and reduces the injury to the occupant compartment.

[0059] According to some embodiments of the present invention, referring to Figure 1 、 Figure 2 and Figure 5 , the second suspension bracket 50 is rotatably connected to the subframe 70. Thus, when the subframe 70 is impacted, the powertrain 80 can rotate relative to the subframe 70 around the second suspension bracket 50, thereby being able to adjust the movement direction of the powertrain 80, and further effectively avoiding the intrusion of the powertrain 80 into the front bulkhead.

[0060] According to some embodiments of the present invention, referring to Figure 1 、 Figure 2 and Figure 5 ,the front end of the second suspension bracket 50 (such as Figure 2 the front end of the second suspension bracket 50 shown) is provided with a second fixing hole 12, and the fourth fastener 60 passes through the second fixing hole 12 to fix the powertrain 80 to the second suspension bracket 50. Thus, the fixing form of fixing the powertrain 80 to the second suspension bracket 50 by the fourth fastener 60 has a simple structure and is convenient for installation, thereby improving the installation efficiency. Preferably, the fourth fastener 60 is a bolt, and the bolt has a low cost and is convenient for batch use.

[0061] Further, as shown in Figure 1 , Figure 2 and Figure 5 , a second bushing 51 is provided at the rear end of the second suspension bracket 50 (the rear end of the second suspension bracket 50 as shown in Figure 2 ). The second suspension bracket 50 is rotatably connected to the subframe 70 through the second bushing 51. Thus, the second bushing 51 can ensure the normal rotation of the second suspension bracket 50 relative to the subframe 70. When the subframe 70 is impacted, the movement direction of the power assembly 80 can be adjusted through the second bushing 51.

[0062] For example, as shown in Figure 1 , Figure 2 and Figure 5 , a second bushing 51 is provided at the rear end of the second suspension bracket 50. The second bushing 51 has the same structure as the first bushing 13. The fourth fastener 60 passes through the second bushing 51 to fix the second suspension bracket 50 to the subframe 70.

[0063] When the vehicle is impacted, the subframe 70 bears the impact force. The subframe 70 transmits the impact force to the first fastener 20. When the first fastener 20 breaks at a preset value, at this time, the second fastener 30 moves along the extension direction of the second fixing hole 12 in the second fixing hole 12, causing the front end of the power assembly 80 to move upward. At the same time, the second bushing 51 of the second suspension bracket 50 rotates, causing the second suspension bracket 50 to rotate relative to the subframe 70, realizing the rotation of the front end of the power assembly 80 around the second bushing 51 towards the lower rear of the vehicle, thereby avoiding the power assembly 80 from impacting the front bulkhead.

[0064] The vehicle according to the second aspect embodiment of the present invention, referring to Figure 1 and Figure 2 and Figure 3 , includes the suspension assembly 100 of the first aspect of this embodiment.

[0065] For the vehicle according to the embodiment of the present invention, by providing the suspension assembly 100 of the first aspect embodiment above, and providing the first fixing hole 11 and the second fixing hole 12 on the first suspension bracket 10, the force transmission path for the subframe 70 to transmit the impact force to the power assembly 80 can be disconnected within a certain stroke, thereby protecting the safety of the occupants in the passenger compartment, improving the vehicle safety performance. At the same time, a collapse stroke can be added to the power assembly 80, reducing the intrusion of the power assembly 80 into the passenger compartment.
