When a vehicle has a small offset collision, the pressure on the collision part is large and a large degree of collapse will occur, causing the wheels to be violently impacted. At this time, in order to prevent the wheels from invading the passenger compartment, a breakable structure can be provided at the connection. When the vehicle collides, the wheels can be thrown outwards of the vehicle body, thereby improving the vehicle use safety.

[0066] Specifically, the subframe assembly 100 is provided with a longitudinal frame beam structure and a lower control arm 5. The lower control arm 5 can be connected to the inclined section 11 of the longitudinal frame beam 1 through a mounting bracket 3. An installation portion 51 is provided at the inner front end of the lower control arm 5. The installation portion 51 can extend from the through hole 351 into the installation cavity 35. After the installation portion 51 is placed in the installation cavity 35, it can be movably connected to the mounting bracket 3 through a frangible connecting member 6. Thus, the lower control arm 5 can be movably connected to the mounting bracket 3 through the frangible connecting member 6. The connection method is simple and convenient for installation. The outer side of the lower control arm 5 can be relatively fixed to the wheel, that is, one side of the lower control arm 5 can be movably connected to the inclined section 11 of the longitudinal frame beam 1, and the other side can be relatively fixed to the wheel. Thus, the wheel can be movable relative to the inclined section 11 of the longitudinal frame beam 1.

[0067] Moreover, the inner rear end of the lower control arm 5 is movably connected to the longitudinal frame beam 1. That is, according to the overall vehicle design requirements, the inner rear end of the lower control arm 5 can be connected to the inclined section 11 of the longitudinal frame beam 1, or the inner rear end of the lower control arm 5 can be connected to the non-inclined section of the longitudinal frame beam 1. Herein, the inner and outer directions are along the transverse direction of the vehicle, that is, the Y direction, and the inner is the direction close to the vehicle center line, and the outer is the direction away from the vehicle center line.

[0068] Furthermore, when a vehicle has an offset collision, the collision force will act on the wheel and then be conducted from the wheel to the lower control arm 5. The installation portion 51 of the lower control arm 5 is connected to the mounting bracket 3 through the frangible connecting member 6. The mounting bracket 3 can act on the frangible connecting member 6 during the collision and cause the frangible connecting member 6 to break. When there is a relative displacement trend between the lower control arm 5 under the action of the force and the mounting bracket 3, the mounting bracket 3 can generate a force on the frangible connecting member 6. Depending on the magnitude of the collision force, the magnitude of the force will also be different, and the magnitude of the force that the frangible connecting member 6 can withstand has a set value.

[0069] When the force exerted by the mounting bracket 3 on the frangible connecting member 6 is greater than the set value that the frangible connecting member 6 can withstand by itself, the force generated by the mounting bracket 3 on the frangible connecting member 6 can cause the frangible connecting member 6 to break. Thus, the wheel can be separated from the longitudinal frame beam 1, avoiding the wheel from invading the occupant compartment due to the collision force, ensuring the safety of vehicle use. Moreover, only the frangible connecting member 6 is caused to break by the force, which can reduce the damage of other components and lower the vehicle's later maintenance cost.

[0070] Among them, it should be noted that the collisions of the vehicle include frontal collisions and offset collisions, etc. Among them, the frontal collision can be a collision from directly in front of the vehicle's traveling direction, and the offset collision can be a collision from the left front or right front of the vehicle's traveling direction. The breakable connecting member 6 in the present invention can break during both frontal collisions and offset collisions, and can effectively swing the lower control arm 5 outward, avoiding the wheels connected to the lower control arm 5 from invading the passenger compartment and posing a safety hazard to the passengers. Especially during offset collisions, the included angle between the extending direction of the inclined section 11 of the longitudinal frame beam 1 and the acting direction of the offset collision force is smaller, so that the collision force on the inclined section 11 acts on the breakable connecting member 6, making the breakable connecting member 6 more likely to break, which is beneficial to improving the safety of passengers during offset collisions.

[0071] According to the subframe assembly 100 of the embodiment of the present utility model, the lower control arm 5 is movably connected to the mounting bracket 3 through the breakable connecting member 6. And when the acting force borne by the breakable connecting member 6 during offset collisions is greater than the set value, the breakable connecting member 6 can break, thereby ensuring the safety of vehicle use. At the same time, only the breakable connecting member 6 breaks during offset collisions, thereby reducing the vehicle's later maintenance cost, having a better use effect, and a wider application range.

[0072] In some embodiments, the breakable connecting member 6 is configured as a connecting bolt, and the mounting portion 51 is configured as a mounting sleeve, and the mounting sleeve is sleeved outside the connecting bolt.

[0073] Specifically, as Figure 1 - Figure 2 shown, the lower control arm 5 can be connected to the mounting bracket 3 through the breakable connecting member 6. The breakable connecting member 6 can be set as a connecting bolt, etc. The connecting bolt can respectively pass through the mounting bracket 3 and the mounting portion 51 of the lower control arm 5, thereby connecting the mounting bracket 3 and the lower control arm 5. And the mounting portion 51 is set as a mounting sleeve, and the mounting sleeve can be sleeved outside the connecting bolt, that is, the connecting bolt can be placed inside the mounting sleeve. The connecting bolt is provided with a connecting nut 7 that cooperates with it to relatively fix the connecting bolt, ensuring the connection reliability, with a convenient connection method and reduced setting cost.

[0074] Furthermore, the connecting bolt can respectively pass through the mounting bracket 3 and the mounting sleeve, and the mounting sleeve can be placed inside the mounting cavity 35. The connecting bolt can pass through the front side plate 31 and the rear side plate 33 in the front-rear direction. The front side plate 31 is provided with a first connecting hole 311, and the rear side plate 33 is provided with a second connecting hole 331. The connecting bolt can pass through the first connecting hole 311 and the second connecting hole 331 in the front-rear direction in sequence, that is, part of the connecting bolt is placed inside the mounting cavity 35 and passes through the mounting sleeve, thereby enabling the mounting bracket 3 to protect the periphery of the shear position of the connecting bolt, avoiding abnormal breakage of the connecting bolt and ensuring the connection reliability.

[0075] In some embodiments, one of the front side or the rear side of the mounting bracket 3 is provided with a mating sunk groove 36. The connecting bolt penetrates through the mounting bracket 3 in the front-rear direction, and the connecting bolt is connected to the connecting nut 7 at the mating sunk groove 36.

[0076] Specifically, one of the front side or the rear side of the mounting bracket 3 is provided with a mating sunk groove 36. That is, the mating sunk groove 36 can be provided on the front side of the mounting bracket 3, or the mating sunk groove 36 can be provided on the rear side of the mounting bracket 3. When the mating sunk groove 36 is provided on the front side of the mounting bracket 3, it means that the mating sunk groove 36 is provided on the side of the front side plate 31 of the mounting bracket 3 that faces away from the mounting cavity 35. When the mating sunk groove 36 is provided on the rear side of the mounting bracket 3, it means that the mating sunk groove 36 is provided on the side of the rear side plate 33 of the mounting bracket 3 that faces away from the mounting cavity 35. The connecting bolt penetrates through the mounting bracket 3 in the front-rear direction, that is, the connecting bolt can penetrate through the mounting bracket 3 from front to back, or can penetrate through the mounting bracket 3 from back to front.

[0077] Furthermore, the connecting bolt is connected to the connecting nut 7 at the mating sunk groove 36. When the connecting bolt penetrates through the mounting bracket 3 from front to back, the mating sunk groove 36 is provided on the side of the rear side plate 33 that faces away from the mounting cavity 35, so that the connecting bolt is connected to the connecting nut 7 on the side of the rear side plate 33 that faces away from the mounting cavity 35. When the connecting bolt penetrates through the mounting bracket 3 from back to front, the mating sunk groove 36 is provided on the side of the front side plate 31 that faces away from the mounting cavity 35, so that the connecting bolt is connected to the connecting nut 7 on the side of the front side plate 31 that faces away from the mounting cavity 35. The connecting nut 7 can be partially placed in the mating sunk groove 36 to limit the connecting nut 7 by the mating sunk groove 36, thereby ensuring the reliability of the installation of the connecting nut 7 and the connecting bolt.

[0078] In some embodiments, the mounting bracket 3 is detachably connected to the inclined section 11 through a bracket mounting member 4; wherein, the frangible connecting member 6 is configured as a connecting bolt, and the bracket mounting member 4 is configured as a mounting bolt, and the shear strength of the mounting bolt is greater than that of the connecting bolt.

[0079] Specifically, the mounting bracket 3 is detachably connected to the inclined section 11 of the vehicle frame longitudinal beam 1 through the bracket mounting member 4, so that the mounting bracket 3 is detachable relative to the vehicle frame longitudinal beam 1, and the lower swing arm 5 is connected to the vehicle frame longitudinal beam 1 through the mounting bracket 3, so that the lower swing arm 5 is also detachable relative to the inclined section 11, which is convenient for the installation of the lower swing arm 5 and subsequent maintenance, etc., saving maintenance costs, etc. The bracket mounting member 4 can be set as a mounting bolt, etc. The mounting bolt can pass through the mounting bracket 3 and the vehicle frame longitudinal beam 1 respectively, so that the mounting bracket 3 and the vehicle frame longitudinal beam 1 are connected. The vehicle frame longitudinal beam 1 is formed with a mating portion 113 that cooperates with the mounting bolt. The mating portion 113 can be set as a welding nut, so as to fix the mounting bolt, ensure the connection reliability, the connection method is convenient, and the setting cost can be reduced.

[0080] Furthermore, the lower swing arm 5 can be connected to the mounting bracket 3 through a breakable connecting piece 6. The breakable connecting piece 6 can be set to a connecting bolt, etc. The connecting bolt can be respectively passed through the mounting portion 51 of the mounting bracket 3 and the lower swing arm 5, so as to connect the mounting bracket 3 and the lower swing arm 5, and a connecting nut 7 matched with the connecting bolt is provided to make the connecting bolt relatively fixed, thereby ensuring the connection reliability. The connection method is convenient and the setting cost can be reduced.

[0081] Moreover, the shear strength of the mounting bolts is greater than the shear strength of the connecting bolts, that is, the shear strength of the connecting bolts is lower, so that when the mounting bolts and the connecting bolts are subjected to the same shear force, the connecting bolts will break first, thereby preventing the collision force generated during a collision from being transmitted to structures such as the mounting bracket 3 and the frame longitudinal beam 1, thereby extending the service life of the frame longitudinal beam 1 and the mounting bracket 3, etc.

[0082] In some embodiments, there are two frame longitudinal beams 1, and a frame cross beam 2 is connected between the two frame longitudinal beams 1, and both frame longitudinal beams 1 are provided with mounting brackets 3; there are two lower swing arms 5, and the two lower swing arms 5 are connected to the mounting brackets 3 of the two frame longitudinal beams 1 in a one-to-one correspondence.

[0083] Specifically, as shown in the figure, the subframe assembly 100 is provided with a frame longitudinal beam 1, which is arranged inside the vehicle body and extends in the front-rear direction. The frame longitudinal beam 1 can be provided with two frame longitudinal beams 1, and the two frame longitudinal beams 1 are arranged to be spaced apart in the transverse direction, so as to play a bearing role. A frame cross beam 2 is arranged between the two frame longitudinal beams 1, and the frame cross beam 2 extends in the transverse direction. The two ends of the frame cross beam 2 are respectively connected to the two frame longitudinal beams 1 by welding or the like, so as to play an all-round bearing role for the vehicle body, and can also transmit and reduce vibration when the vehicle is running, so as to ensure the comfort of the vehicle.

[0084] Furthermore, both frame longitudinal beams 1 are provided with mounting brackets 3, that is, two mounting brackets 3 are provided, and the two mounting brackets 3 are respectively connected to the sides of the two frame longitudinal beams 1 away from each other, and two lower control arms 5 are also provided, and the two lower control arms 5 are arranged in a one-to-one correspondence with the two mounting brackets 3, that is, the two lower control arms 5 can be connected to the corresponding frame longitudinal beams 1 through the two mounting brackets 3, respectively, and the lower control arms 5 and the mounting brackets 3 are connected through breakable connectors 6, that is, when the vehicle is subjected to an offset collision, the breakable connectors 6 on both sides can be broken according to the situation, thereby preventing wheels and the like from intruding into the passenger compartment, thereby ensuring the safety of vehicle use.

At the same time, only the breakable connecting member 6 breaks during an offset collision, thereby reducing the later maintenance cost of the vehicle, with better use effects and a wider application range.
