Description

Technical Field

[0001] This utility model relates to the field of automotive equipment technology, and in particular to an air suspension airbag underpinning. Background Technology

[0002] Air suspension systems, as a crucial component of modern vehicle suspension technology, are widely used in commercial vehicles, buses, and high-end passenger vehicles. They dynamically adjust vehicle height and stiffness by regulating the air pressure within the airbags, thereby improving ride comfort, stability, and load adaptability. In air suspension systems, the lower airbag support, as a key structural component connecting the axle and the airbag, must not only withstand complex loads from the axle, such as vertical, lateral, and longitudinal forces, but also provide a reliable mounting point for components such as the thrust rod, shock absorbers, and stabilizer bar.

[0003] With the market demand for small cars showing a continuous upward trend, more and more consumers are inclined to choose small cars. However, the design and manufacturing process of small cars faces many challenges, among which the traditional air suspension lower support is a problem that cannot be ignored. Due to its structural characteristics, this traditional lower support often requires a large amount of space. In today's increasingly compact vehicle designs, where each component needs to be carefully arranged to optimize space utilization, this characteristic becomes particularly disadvantageous. It greatly limits the flexibility of engineers in vehicle layout, making it difficult for them to achieve the optimal placement of other components within limited space, which may affect many aspects of the vehicle, such as performance, comfort, and effective space utilization.

[0004] To overcome the above problems, it is urgent to design an integrated air suspension airbag underpinning. By optimizing the structural layout and force transmission path, and adding local reinforcing ribs, the overall rigidity can be improved, the weight can be reduced, and the positioning accuracy and reliability of each functional connecting seat can be ensured. Utility Model Content

[0005] Therefore, this utility model provides an air suspension airbag lower support to overcome the problem that the existing air suspension airbag lower support restricts the flexibility of vehicle layout.

[0006] To achieve the above objectives, this utility model provides:

[0007] The air suspension airbag lower support assembly is an integral structure, which includes a positioning section and a supporting section. The positioning section includes an axle connecting seat, which is a horizontal plate shape. One end of the axle connecting seat extends downward to provide an n-shaped lower thrust rod connecting seat, and the other end of the axle connecting seat away from the n-shaped lower thrust rod connecting seat extends upward to provide a shock absorber connecting seat.

[0008] The receiving section includes a T-shaped upright plate extending upward along the middle of the axle connecting seat and an airbag platform set on the top of the T-shaped upright plate. The airbag platform extends horizontally to the left along the top of the T-shaped upright plate. A transverse stabilizer connecting seat is provided at the bottom of the narrow wall of the T-shaped upright plate near the n-shaped lower thrust rod connecting seat, and an upper thrust rod connecting seat is provided at the upper end on the same side. A transverse thrust rod connecting seat is provided at the bottom of the wide wall of the T-shaped upright plate.

[0009] Furthermore, the axle connecting seat has positioning holes at the four corners of its bottom surface and an annular groove for fixing at the center of its bottom surface.

[0010] Furthermore, the top surface of the airbag platform is provided with a cross-shaped protrusion.

[0011] Furthermore, a first reinforcing rib is provided at the extended position between the T-shaped upright plate and the axle connecting seat to strengthen the T-shaped upright plate and the axle connecting seat.

[0012] Furthermore, a second reinforcing rib is provided at the extension position between the T-shaped upright plate and the airbag platform to strengthen the T-shaped upright plate and the airbag platform.

[0013] Furthermore, the extended positions of the axle connector and the shock absorber connector are provided with a third reinforcing rib to strengthen the axle connector and the shock absorber connector.

[0014] Furthermore, a fourth reinforcing rib is provided between the lateral stabilizer bar connector and the n-shaped lower thrust bar connector to strengthen the lateral stabilizer bar connector and the n-shaped lower thrust bar connector.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by adopting an integral structure, the number of parts and assembly processes are reduced, problems such as loosening and abnormal noise are reduced, the overall stability and reliability are improved, and the service life is extended.

[0016] Furthermore, the four corner positioning holes on the bottom surface of the horizontal plate-shaped axle connecting seat facilitate quick and accurate installation and positioning, while the central annular groove enhances the fixing effect with the axle, prevents relative displacement, and ensures driving safety.

[0017] Furthermore, the n-shaped structure extending downwards at one end of the axle connector provides a stable connection point for the lower thrust rod, effectively transmitting longitudinal force and ensuring smooth driving and handling.

[0018] Furthermore, the upward extension of the other end of the axle connector facilitates the connection of the shock absorber, better enhances its damping effect, and improves ride comfort.

[0019] Furthermore, the T-shaped upright plate extending upwards along the middle of the axle connector provides stable support for the airbag platform, which in turn provides a suitable installation position for the air suspension airbag, ensuring the normal operation of the airbag and the vehicle's suspension function.

[0020] Furthermore, the connecting seat is installed at the bottom of the narrow wall of the T-shaped upright plate to connect the lateral stabilizer bar, thereby enhancing lateral stability, reducing cornering roll, and improving driving safety.

[0021] Furthermore, an upper thrust rod connecting seat is provided on the upper end of the same side, which, together with the lower thrust rod, optimizes the longitudinal force transmission and improves the handling performance.

[0022] Furthermore, a lateral thrust rod is installed at the bottom of the wide wall of the T-shaped upright plate to enhance the vehicle's ability to cope with lateral forces and improve driving stability.

[0023] Furthermore, the cross-shaped protrusion on the top surface increases friction with the airbag, preventing slippage and also serving a positioning function, thus improving installation efficiency and accuracy.

[0024] Furthermore, the first reinforcing rib strengthens the connection between the T-shaped upright plate and the axle connecting seat, improving the overall structural rigidity and reducing the risk of deformation and damage.

[0025] Furthermore, the second reinforcing rib strengthens the T-shaped upright plate to support the airbag platform, ensuring the stability of the airbag platform and guaranteeing the normal operation of the air suspension system.

[0026] Furthermore, the third reinforcing rib strengthens the connection between the axle connecting seat and the shock absorber connecting seat, enabling the shock absorber to stably transmit the damping force, improve the damping effect, and extend the service life of the connection parts.

[0027] Furthermore, the fourth reinforcing rib strengthens the structural strength of the lateral stabilizer bar connector and the U-shaped lower thrust bar connector, enabling them to work together to cope with complex stresses and improve the overall stability and reliability of the vehicle.

[0028] This utility model's air suspension airbag lower support adopts an integral structure. The axle connecting seat, each connecting seat, the supporting section, and the airbag platform are rationally designed, and the structure is reinforced by multiple reinforcing ribs. It has significant advantages in saving vehicle layout space, ensuring installation, transmitting force, and improving stability and reliability. Attached Figure Description

[0041] One embodiment of this utility model provides an air suspension airbag underpinning.

[0042] The air suspension airbag lower support assembly is an integral structure, which includes a positioning section and a supporting section. The positioning section includes an axle connecting seat 1, which is a horizontal plate shape. One end of the axle connecting seat 1 extends downward to provide an n-shaped lower thrust rod connecting seat 2, and the other end of the axle connecting seat 1 away from the n-shaped lower thrust rod connecting seat 2 extends upward to provide a shock absorber connecting seat 3.

[0043] Specifically, one end of the axle connecting seat 1 extends downward to provide an n-shaped lower thrust rod connecting seat. This structural design provides a stable and reliable connection point for the lower thrust rod, enabling it to effectively transmit longitudinal forces during vehicle operation and ensuring vehicle stability and handling. The end of the axle connecting seat 1 away from the lower thrust rod connecting seat extends upward to provide a shock absorber connecting seat 3, facilitating connection with the shock absorber and allowing it to better perform its damping function, effectively buffering vibrations generated during vehicle operation and improving ride comfort.

[0044] The receiving section includes a T-shaped upright plate 4 extending upward along the middle of the axle connecting seat 1 and an airbag platform 5 set on the top of the T-shaped upright plate 4. The airbag platform 5 extends horizontally to the left along the top of the T-shaped upright plate 4. A transverse stabilizer connecting seat 6 is provided at the bottom of the narrow wall of the T-shaped upright plate 4 near the n-shaped lower thrust rod connecting seat 2, and an upper thrust rod connecting seat 7 is provided at the upper end on the same side. A transverse thrust rod connecting seat 8 is provided at the bottom of the wide wall of the T-shaped upright plate 4.

[0045] Specifically, the receiving section includes a T-shaped upright plate extending upwards along the middle of the axle connecting seat 1 and an airbag platform 5 located on top of the T-shaped upright plate. The airbag platform 5 extends horizontally to the left along the top of the T-shaped upright plate. This structural layout is reasonable. The T-shaped upright plate provides stable support for the airbag platform 5, while the airbag platform 5 provides a suitable installation position for the air suspension airbag, ensuring the normal operation of the airbag and realizing the vehicle's suspension function.

[0046] Specifically, a lateral stabilizer bar connector 6 is located at the bottom of the narrow wall near the lower thrust rod connector of the T-shaped upright plate. This connector connects to the lateral stabilizer bar, enhancing the vehicle's lateral stability, reducing body roll during cornering and other driving conditions, and improving driving safety. An upper thrust rod connector 7 is located at the upper end on the same side, providing a connection point for the upper thrust rod. Working together with the lower thrust rod, this further optimizes the transmission of longitudinal forces and improves the vehicle's handling performance.

[0047] Specifically, a transverse thrust rod connecting seat 8 is provided at the bottom of the wide wall of the T-shaped upright plate, which can connect to the transverse thrust rod, helping the vehicle to better cope with the action of lateral force during driving and enhancing the driving stability of the vehicle.

[0048] Specifically, the lower thrust rod assembly b is connected to the n-shaped lower thrust rod connecting seat of the lower support a of the air suspension airbag; the shock absorber assembly c is connected to the shock absorber connecting seat of the lower support a of the air suspension airbag; the axle d is connected to the axle d connecting seat of the lower support a of the air suspension airbag; the airbag assembly e is connected to the airbag platform of the lower support a of the air suspension airbag; the lateral stabilizer bar f is connected to the lateral stabilizer bar f connecting seat of the lower support a of the air suspension airbag; the upper thrust rod assembly g is connected to the upper thrust rod connecting seat of the lower support a of the air suspension airbag; and the lateral thrust rod h is connected to the lateral thrust rod h connecting seat of the lower support a of the air suspension airbag.

[0049] Specifically, the axle connecting seat 1 has positioning holes 11 at its four corners on its bottom surface, and an annular groove 12 for fixing is provided in the center of its bottom surface. The axle connecting seat 1 is horizontal and has positioning holes 11 at its four corners on its bottom surface, and an annular groove 12 in the center of its bottom surface. The positioning holes 11 facilitate quick and accurate positioning of the lower support onto the axle during installation, and the annular groove 12 enhances the fixing effect with the axle, preventing relative displacement between the lower support and the axle during vehicle operation, ensuring the stability of the connection, and guaranteeing driving safety.

[0050] Specifically, the top surface of the airbag platform 5 is provided with a cross-shaped protrusion 51. The cross-shaped protrusion 51 on the top surface of the airbag platform 5 can increase the friction between the airbag and the airbag platform 5, preventing the airbag from sliding during vehicle operation; on the other hand, the cross-shaped structure can play a certain positioning role, facilitating the installation and positioning of the airbag, and improving installation efficiency and accuracy.

[0051] Specifically, a first reinforcing rib 14 is provided at the extension position between the T-shaped upright plate 4 and the axle connecting seat 1 to strengthen the connection between them. The first reinforcing rib 14 at the extension position between the T-shaped upright plate and the axle connecting seat 1 effectively enhances the connection strength between them, improves the rigidity of the overall structure of the lower support, and enables it to better withstand various stresses generated during vehicle operation, reducing the risk of structural deformation and damage.

[0052] Specifically, a second reinforcing rib 45 is provided at the extension position between the T-shaped upright plate 4 and the airbag platform 5 to strengthen both the T-shaped upright plate 4 and the airbag platform 5. The second reinforcing rib 45 at the extension position between the T-shaped upright plate and the airbag platform 5 enhances the support provided by the T-shaped upright plate to the airbag platform 5, ensuring the airbag platform 5 remains stable when subjected to airbag pressure and vehicle vibration, thus guaranteeing the normal operation of the air suspension system.

[0053] Specifically, the extended positions of the axle connecting seat 1 and the shock absorber connecting seat 3 are provided with third reinforcing ribs 13 to strengthen them. The presence of the third reinforcing ribs 13 at the extended positions of the axle connecting seat 1 and the shock absorber connecting seat 3 enhances the connection strength between them, enabling the shock absorber to transmit damping force more stably, improving the damping effect, and extending the service life of the connection parts.

[0054] Specifically, a fourth reinforcing rib 26 is provided between the lateral stabilizer bar connector 6 and the n-shaped lower thrust rod connector 2 to strengthen both components. This fourth reinforcing rib 26 strengthens the structural strength between the two critical connection points, enabling them to work together more effectively to cope with the complex stresses generated during vehicle operation, thereby improving the overall stability and reliability of the vehicle.

[0055] This utility model features an ingeniously designed overall structure for the air suspension airbag lower support assembly. The positioning and supporting sections are rationally laid out and securely connected. Multiple reinforcing ribs further strengthen the structure, effectively improving vehicle stability, safety, and overall vehicle layout flexibility. For those skilled in the art, based on the concepts of this utility model, variations in specific implementation methods and application scope are possible. Therefore, the content of this specification should not be construed as limiting this utility model.
