[0032] With the development of the automotive industry and technological progress, the usage scenarios and functions of automobiles are constantly expanding. Among them, the cargo space utilization rate of automobiles refers to the ratio of the volume of the passenger compartment to the overall volume of the automobile.

[0033] Currently, how to improve the utilization rate of automobiles in storage has become an urgent problem to be solved.

[0034] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle according to one or more embodiments of this application.

[0035] Vehicle 1 can be a new energy vehicle, such as a hybrid vehicle or a range-extended vehicle. Vehicle 1 can be a front-wheel drive vehicle, a four-wheel drive vehicle, etc. Vehicle 1 includes a body suspension assembly 2, which provides a basic support structure for vehicle 1, limits the passenger space of vehicle 1, and provides vehicle 1 with stable and controllable driving capabilities.

[0036] Reference Figure 2 , Figure 2 This is a structural schematic diagram of a vehicle suspension assembly according to one or more embodiments of this application.

[0037] To address the aforementioned problems, this application provides a vehicle suspension assembly 2, which includes a front suspension system 100 and a body assembly 200. The front suspension system 100 is connected to the body assembly 200, and the body assembly 200 defines an occupant space 201. The front suspension system 100 includes a steering knuckle 10, an upper control arm 20, a lower control arm 30, and a shock absorber 40. The upper control arm 20 is connected to one end of the steering knuckle 10; the lower control arm 30 is connected to the other end of the steering knuckle 10 away from the upper control arm 20, and the lower control arm 30 and the upper control arm 20 are spaced apart to form an accommodating space 31; the shock absorber 40 is connected to the upper control arm 20 and extends to the side of the upper control arm 20 away from the lower control arm 30; wherein at least a portion of the body assembly 200 is disposed within the accommodating space 31, so that the occupant space 201 extends between the upper control arm 20 and the lower control arm 30.

[0038] The front suspension system 100 serves to establish a buffer and support between the body assembly 200 and the wheels, helping to precisely control wheel movement to achieve a dynamic balance between vehicle handling stability and ride comfort. The front suspension system 100 refers to the suspension system located closer to the front of the vehicle 1 in the direction of travel. The body assembly 200 defines an occupant space 201, thereby accommodating occupants and cargo, etc., while also providing support and protection for the occupants and cargo within the occupant space 201. It is understood that the occupant space 201 refers to the space defined by the body assembly 200 that can accommodate occupants and cargo, within which occupants can move freely.

[0039] The steering knuckle 10 is an important component of the steering axle of vehicle 1, enabling vehicle 1 to drive stably and transmit driving direction sensitively. The shock absorber 40 can be used to dampen vibrations caused by road impacts, improving the ride comfort and handling safety of vehicle 1. The lower control arm 30 is located downstream of the upper control arm 20 in the direction of gravity. The lower control arm 30 and the upper control arm 20 are spaced apart, and a receiving space 31 is formed between the lower control arm 30 and the upper control arm 20. The receiving space 31 can be used to accommodate part of the body component 200. It is understood that the shock absorber 40 is connected to the upper control arm 20 and extends to the side of the upper control arm 20 away from the lower control arm 30. This allows the shock absorber 40 to avoid the receiving space 31, reducing the space occupied by the shock absorber 40 between the upper control arm 20 and the lower control arm 30. This facilitates the extension of the passenger space 201 defined by the part of the body component 200 located in the receiving space 31 to the space between the upper control arm 20 and the lower control arm 30. At the same time, it can improve the flexibility of the end of the shock absorber 40 away from the upper control arm 20. As an example, the passenger space 201 extending between the upper control arm 20 and the lower control arm 30 can be used to accommodate the feet and legs of passengers. For instance, the driver of vehicle 1 can place their feet and part of their legs between the upper control arm 20 and the lower control arm 30, thereby increasing the passenger space 201 while ensuring sufficient distance between the driver's feet and legs and the shock absorber 40. It should be noted that if the passenger space 201 extending between the upper control arm 20 and the lower control arm 30 is used to accommodate the feet and legs of passengers, it also facilitates placing the front passenger seats of vehicle 1, such as the driver's seat, closer to the front of vehicle 1, thereby improving the layout flexibility and space utilization of the passenger space 201.

[0040] Through the above implementation, the shock absorber 40 is connected to the upper control arm 20 and extends to the side of the upper control arm 20 away from the lower control arm 30. An accommodating space 31 is formed between the upper control arm 20 and the lower control arm 30, which facilitates the shock absorber 40 to avoid the body component 200 located in the accommodating space 31, reduces the risk of interference between the shock absorber 40 and the body component 200, and allows the passenger space 201 to extend between the upper control arm 20 and the lower control arm 30, thereby increasing the volume of the passenger space 201 and improving the cargo space utilization rate.

[0041] Combination Figures 3-4 , Figure 3 This is an exploded structural diagram of a vehicle suspension assembly according to one or more embodiments of this application; Figure 4 This is a schematic diagram of the structure of the first arm of a vehicle suspension assembly according to one or more embodiments of this application.

[0042] In some embodiments, the upper control arm 20 includes a first connecting portion 21, a first support arm 22, and a second support arm 23. The first connecting portion 21 is connected to the steering knuckle 10, and the first connecting portion 21 is connected to both the first support arm 22 and the second support arm 23. The upper control arm 20 also includes a support rod 24, one end of which is connected to the first support arm 22, and the other end of which is connected to the second support arm 23. The shock absorber 40 is connected to the support rod 24. The first connecting portion 21 may be, but is not limited to, a ball joint pin. An upper control arm mounting point may be provided on the steering knuckle 10, thereby connecting the upper control arm to the first connecting portion 21. It should be noted that the first connecting portion 21, the first support arm 22, the second support arm 23, and the support rod 24 can constitute an integral upper control arm 20, thereby improving the rigidity and strength of the upper control arm 20. The first support arm 22, the second support arm 23, and the first connecting portion 21 can be fitted together in a U-shape, and the lateral stiffness of the U-shaped structure is large, thereby effectively absorbing the lateral force from the wheel. Support rod 24 is connected to the first arm 22 and the second arm 23 respectively, which can improve the structural strength of the upper swing arm 20. Simultaneously, support rod 24 is connected to the vibration damper 40, providing fixation and support for the vibration damper 40, thus improving the installation stability of the vibration damper 40. In some applications, the vibration damper 40 can be sleeved on the support rod 24. This further improves the connection stability between the vibration damper 40 and the upper swing arm 20.

[0043] In some embodiments, the vehicle suspension assembly 2 further includes a mounting shaft 50, and the upper control arm 20 further includes a fourth connecting portion 25 and a fifth connecting portion 26. The fourth connecting portion 25 is connected to the end of the first support arm 22 away from the first connecting portion 21, and the fifth connecting portion 26 is connected to the end of the second support arm 23 away from the first connecting portion 21. The mounting shaft 50 is connected to the fourth connecting portion 25 and the fifth connecting portion 26 respectively, and the mounting shaft 50 is connected to the vehicle body assembly 200. The fourth connecting portion 25 and the fifth connecting portion 26 may be, but are not limited to, flexible bushings. The mounting shaft 50 is a transverse shaft structure for mounting and fixing to the vehicle body assembly 200. Exemplarily, the fourth connecting portion 25 and the fifth connecting portion 26 are flexible bushings, one end of the mounting shaft 50 can be inserted into the fourth connecting portion 25, and the other end of the mounting shaft 50 is inserted into the fifth connecting portion 26. Therefore, the upper control arm 20 is connected to the mounting shaft 50 through the fourth connecting part 25 and the fifth connecting part 26, and is connected to the body assembly 200 through the mounting shaft 50, which reduces the installation difficulty of the upper control arm 20 and the body assembly 200 and saves production costs.

[0044] Combination Figure 5 , Figure 5 This is a structural schematic diagram of a shock absorber in a vehicle suspension assembly according to one or more embodiments of this application.

[0045] In some embodiments, the shock absorber 40 includes a shock absorber body 41 and a second connecting portion 42. The second connecting portion 42 is connected to the end of the shock absorber body 41 near the upper control arm 20 and is also connected to the support rod 24. It is understood that the shock absorber body 41 can be used to attenuate vibration energy caused by road impacts. The second connecting portion 42 is used to connect to the support rod 24. It should be noted that after assembly, the second connecting portion 42 is located downstream of the shock absorber body 41 in the direction of gravity. The connection method between the second connecting portion 42 and the shock absorber body 41 can include, but is not limited to, welding. Thus, the shock absorber body 41 is connected to the support rod 24 via the second connecting portion 42, reducing the installation difficulty of the shock absorber 40 and the upper control arm 20, improving the connection stability of the shock absorber 40 and the upper control arm 20, facilitating the better extension of the shock absorber 40 to the side of the upper control arm 20 away from the lower control arm 30, and reducing the risk of interference between the shock absorber 40 and the body components 200 within the accommodating space 31.

[0046] In some embodiments, the shock absorber 40 further includes a third connecting portion 43, which is connected to the end of the shock absorber body 41 away from the upper control arm 20 and is connected to the body assembly 200. The shock absorber body 41 can be connected to the body assembly 200 via the third connecting portion 43. It should be noted that after assembly, the third connecting portion 43 is located upstream of the shock absorber body 41 in the direction of gravity. The connection method between the third connecting portion 43 and the shock absorber body 41 can include, but is not limited to, welding. In some application scenarios, the third connecting portion 43 and the second connecting portion 42 can have the same structure; for example, both the third connecting portion 43 and the second connecting portion 42 can be ball joint bushings. Thus, the shock absorber body 41 is connected to the body assembly 200 via the third connecting portion 43, reducing the installation difficulty of the shock absorber 40 and the body assembly 200 and improving the connection stability of the shock absorber 40 and the body assembly 200.

[0047] In some embodiments, the shock absorber body 41 includes a connecting rod 411, an oil reservoir 412, and a welding bracket 413. The connecting rod 411 is connected to the oil reservoir 412, and the welding bracket 413 is disposed on the side of the oil reservoir 412 away from the connecting rod 411. The welding bracket 413 is connected to the second connecting part 42, and the connecting rod 411 is connected to the third connecting part 43. The connecting rod 411 can be used to transmit the movement of the body assembly 200 to the piston inside the shock absorber body 41. When the shock absorber 40 is working, the connecting rod 411 can drive the piston to move within the oil reservoir 412 containing hydraulic oil. The welding bracket 413 can be disposed on the outside of the oil reservoir 412. It is understood that the welding bracket 413 can be welded to the second welding part, and the end of the connecting rod 411 away from the oil reservoir 412 can be welded to the third connecting part 43. Therefore, by welding bracket 413, the installation difficulty of the shock absorber body 41 and the second connecting part 42 can be reduced, and the connection stability of the shock absorber body 41 and the second connecting part 42 can be improved. By connecting the connecting rod 411 and the third connecting part 43, the connection stability of the shock absorber body 41 and the third connecting part 43 is improved.

[0048] In some embodiments, the second connecting portion 42 includes a ball joint portion 421 and a bushing 422. The bushing 422 forms a mounting space 4221 extending through opposite sides of the bushing 422. The ball joint portion 421 is located within the mounting space 4221 and is configured to perform spherical movement within the mounting space 4221. The ball joint portion 421 has a mounting hole 4211, through which it is fitted onto the support rod 24. The bushing 422 is connected to the damper body 41. Exemplarily, the damper body 41 can be welded to the bushing 422. It is understood that the ball joint portion 421 is capable of spherical movement within the mounting space 4221, and the ball joint portion 421 is fitted onto the support rod 24 through the mounting hole 4211. Thus, through the cooperation of the ball joint portion 421 and the bushing 422, the interference movement tendency of the damper body 41 can be decoupled, thereby improving the flexibility and service life of the damper 40. In some applications, the third connecting part 43 may have the same structure as the second connecting part 42.

[0049] Combination Figure 6 , Figure 6 This is a structural schematic diagram of the lower control arm and subframe of a vehicle suspension assembly according to one or more embodiments of this application.

[0050] In some embodiments, the vehicle suspension assembly 2 further includes a subframe 300 connected to the body assembly 200. The lower control arm 30 includes a sixth connection portion 32 and a third support arm 33. The sixth connection portion 32 is connected to the steering knuckle 10, and the third support arm 33 is connected to both the sixth connection portion 32 and the subframe 300. The subframe 300 provides fixation and support for the front suspension system 100 and can be used to isolate vibrations and noise, reducing the risk of vibrations and noise directly entering the passenger compartment 201. The sixth connection portion 32 may include, but is not limited to, a ball joint pin. Exemplarily, a lower control arm mounting point may be provided on the steering knuckle 10, thereby connecting to the sixth connection portion 32 via the lower control arm mounting point. The third support arm 33 is connected to the subframe 300. Exemplarily, a flexible bushing may be provided at the end of the third support arm 33 away from the steering knuckle 10, thereby facilitating the connection of the third support arm 33 to the subframe 300 via the flexible bushing. Therefore, the sixth connecting part 32 improves the connection stability between the lower control arm 30 and the steering knuckle 10, while the third support arm 33 improves the structural strength of the lower control arm 30 and the connection stability between the lower control arm 30 and the subframe 300. It should be noted that since the shock absorber 40 is mounted on the upper control arm 20, the lower control arm 30 does not need a mounting point for the shock absorber 40, thus simplifying the structure of the lower control arm 30, reducing the molding difficulty of the lower control arm 30, and saving costs.

[0051] In some embodiments, the lower control arm 30 further includes a fourth support arm 34, which is connected to both the third support arm 33 and the subframe 300. Exemplarily, a flexible bushing may be provided at the end of the fourth support arm 34 away from the third support arm 33, thereby facilitating the connection of the fourth support arm 34 to the subframe 300 via the flexible bushing. Thus, by connecting the fourth support arm 34 to both the third support arm 33 and the subframe 300, the lower control arm 30 is easily installed on the subframe 300, improving the connection stability between the lower control arm 30 and the subframe 300 and the reliability of the vehicle suspension assembly 2.

[0052] In summary, the vehicle suspension assembly 2 provided in this application includes a front suspension system 100 and a body assembly 200. The front suspension system 100 is connected to the body assembly 200, and the body assembly 200 defines an occupant space 201. The front suspension system 100 includes a steering knuckle 10, an upper control arm 20, a lower control arm 30, and a shock absorber 40. The upper control arm 20 is connected to one end of the steering knuckle 10. The lower control arm 30 is connected to the other end of the steering knuckle 10 away from the upper control arm 20. The lower control arm 30 and the upper control arm 20 are spaced apart to form an accommodating space 31. The shock absorber 40 is connected to the upper control arm 20 and extends to the side of the upper control arm 20 away from the lower control arm 30. At least a portion of the body assembly 200 is disposed within the accommodating space 31 so that the occupant space 201 extends between the upper control arm 20 and the lower control arm 30. Through the above implementation, the shock absorber 40 is connected to the upper control arm 20 and extends to the side of the upper control arm 20 away from the lower control arm 30. An accommodating space 31 is formed between the upper control arm 20 and the lower control arm 30, which facilitates the shock absorber 40 to avoid the body component 200 located in the accommodating space 31, reduces the risk of interference between the shock absorber 40 and the body component 200, and allows the passenger space 201 to extend between the upper control arm 20 and the lower control arm 30, thereby increasing the volume of the passenger space 201 and improving the cargo space utilization rate.
