Description

Technical Field

[0001] This utility model applies to the technical field of suspension structures, and particularly relates to a front airbag seat structure. Background Technology

[0002] Air suspension, characterized by its superior comfort and high load-bearing capacity, is widely used in medium and large buses. Airbags are a crucial component of air suspension; their elastic properties absorb and disperse impacts from the road surface, reducing vibrations transmitted to the vehicle body and providing a smoother driving experience. The upper part of the airbag is mounted on the chassis frame via an airbag mount, while its lower part connects to the axle. With the development of new energy technologies, some models place the battery on the front roof, above the front axle, increasing standing space and passenger capacity, but also increasing the load on the chassis. Currently, the front airbag mount structure of buses equipped with air suspension can be divided into two parts based on structural materials: one part is a steel plate structure, using steel plates to form the front airbag mounting plate and connecting rectangular tubes; the other part is a rectangular tube structure, using processed and bent rectangular tubes to form the load-bearing structure of the front airbag mount, connecting the front airbag mount to the chassis frame. This structure primarily disperses the upward normal force on the airbag seat plate through its overlapping curved tubes and inner passageway frame. From a structural strength perspective, the inner passageway frame is higher than the curved tubes, which leads to excessive stress at the connection between the curved tubes and the airbag seat plate. Under bending conditions, the side frame will deform outwards. The structural strength of the rectangular tube structure of the airbag seat at the connection with the side frame is low in the vertical direction, failing to effectively restrain the side frame and potentially causing cracking at the connection. If a simple front airbag seat structure could be designed that effectively improves vertical structural strength, withstands larger vertical loads and impacts, and enhances the structural strength of the vehicle body under bending conditions, these problems could be solved.

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a front airbag seat structure that is simple in structure, can effectively improve the structural strength in the vertical direction, can withstand large vertical loads and impact forces, and improve the structural strength of the vehicle body under bending conditions.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes an airbag seat plate, a support plate, a passageway frame connecting plate, and a side frame connecting plate. The lower ends of the two sets of support plates are connected to the upper surface of the airbag seat plate. The upper surface of the airbag seat plate is provided with a plurality of stiffeners, which cooperate with the lower ends of the support plates. The passageway frame connecting plate and the side frame connecting plate are respectively connected to the large end and small end of the two sets of support plates. The two sets of support plates are connected to the front mounting position of the vehicle frame through the passageway frame connecting plate.

[0005] Furthermore, the lower end connection of the support plate is provided with a plurality of rib clearance openings, which cooperate with a plurality of rib plates.

[0006] Furthermore, the passageway frame connecting plate is provided with passageway frame connecting plate flanges on both sides, and the passageway frame connecting plate flanges are provided with a plurality of passageway frame connecting plate plug welding holes. The two sets of passageway frame connecting plate flanges are connected to the opposite side of the large end of the two sets of support plates through the plurality of passageway frame connecting plate plug welding holes.

[0007] Furthermore, the side frame connecting plate is provided with side frame connecting plate flanges on both sides, and the side frame connecting plate flanges are provided with a plurality of side frame connecting plate plug welding holes. The two sets of side frame connecting plate flanges are connected to the opposite side of the small end of the two sets of support plates through the plurality of side frame connecting plate plug welding holes.

[0008] Furthermore, the upper end of the two sets of support plates is provided with a reinforcing plate, and the two sides of the reinforcing plate are provided with reinforcing plate flanges. The reinforcing plate flanges are provided with a plurality of reinforcing plate plug welding holes, and the two sets of reinforcing plate flanges are connected to the corresponding side of the upper end of the two sets of support plates through the plurality of reinforcing plate plug welding holes.

[0009] Furthermore, the passageway frame connecting plate, the side frame connecting plate, and the main body of the reinforcing plate are all provided with weight reduction holes.

[0010] Furthermore, several rib drainage outlets are provided at the lower ends of several rib plates, and these rib drainage outlets cooperate with the upper end of the airbag seat plate.

[0011] Furthermore, a plurality of support plate drainage outlets are provided at the lower end connection of the support plate, and the plurality of support plate drainage outlets cooperate with the upper end of the airbag seat plate.

[0013] Furthermore, the airbag seat plate has an air tube connector mounting hole in the middle, which is connected to the air tube end of the external control airbag.

[0014] The beneficial effects of this invention are as follows: By utilizing the characteristics of steel plate structures and increasing the height of the steel plates in the vertical direction, this invention effectively improves the structural strength in the vertical direction, enabling it to withstand larger vertical loads and impact forces. This invention is achieved by attaching the inner passageway frame of the front suspension section and the side frame, respectively. Since both the inner passageway frame and the side frame are vertical structures, their vertical stiffness is high, thereby further improving the structural strength of the vehicle body under bending conditions. The invention is simple in structure and has greater structural strength. Attached Figure Description

[0023] like Figures 1 to 8 As shown, in this embodiment, the present invention includes an airbag seat plate 1, a support plate 2, a passageway frame connecting plate 3, and a side frame connecting plate 4. The lower ends of the two sets of support plates 2 are connected to the upper surface of the airbag seat plate 1. The upper surface of the airbag seat plate 1 is provided with several stiffeners 5, which cooperate with the lower ends of the support plates 2. The passageway frame connecting plate 3 and the side frame connecting plate 4 are respectively connected to the large end and small end of the two sets of support plates 2. The two sets of support plates 2 are connected to the front mounting position of the frame 19 through the passageway frame connecting plate 3. It can be seen that the present invention is formed by connecting and welding the airbag seat plate 1, the support plate 2, the passageway frame connecting plate 3, and the side frame connecting plate 4. The use of multi-component welding instead of a one-piece structure makes the overall stress more uniform and the structural strength greater. The support plate 2 is cut from a steel plate of a certain thickness and is mainly in the shape of a length. The small end is used to overlap the side frame, and the large end is used to overlap the passageway frame.

[0024] like Figures 3 to 5 As shown, in this embodiment, a plurality of rib clearance openings 6 are provided at the lower end connection of the support plate 2, and the plurality of rib clearance openings 6 cooperate with the plurality of rib plates 5. It can be seen that the rib clearance openings 6 can avoid the rib plates 5, and the plurality of rib plates 5 enhance the support strength of the airbag seat plate 1 and prevent deformation during the pressing process.

[0025] like Figure 2 , Figure 3 as well as Figure 6 As shown, in this embodiment, the aisle frame connecting plate 3 has aisle frame connecting plate flanges 7 on both sides. Each aisle frame connecting plate flange 7 has several aisle frame connecting plate plug welding holes 8. The two sets of aisle frame connecting plate flanges 7 are connected to the opposite side of the large ends of the two sets of support plates 2 through these several aisle frame connecting plate plug welding holes 8. Thus, the aisle frame connecting plate 3 is a channel steel structure with aisle frame connecting plate flanges 7 on both sides. Each aisle frame connecting plate flange 7 has several small-sized aisle frame connecting plate plug welding holes 8. The aisle frame connecting plate 3 is welded to the aisle frame connecting end of the support plate through these small-sized aisle frame connecting plate plug welding holes 8. The main body of the aisle frame connecting plate 3 fixes the two sets of support plates 2 and the airbag seat plate 1 to the vehicle frame 19, providing overall support.

[0026] like Figure 2 , Figure 3 as well as Figure 7 As shown, in this embodiment, the side frame connecting plate 4 is provided with side frame connecting plate flanges 9 on both sides. Each side frame connecting plate flange 9 has several side frame connecting plate plug welding holes 10. The two sets of side frame connecting plate flanges 9 are connected to the opposite side of the small ends of the two sets of support plates 2 through these several side frame connecting plate plug welding holes 10. Therefore, the side frame connecting plate 4 is designed with side frame connecting plate flanges 9 on both sides, and several small-sized side frame connecting plate plug welding holes 10 are designed on the side frame connecting plates 9. The side frame connecting plate 4 is welded to the side frame connecting end of the support plate 2 through these small-sized side frame connecting plate plug welding holes 10.

[0027] like Figure 2 , Figure 3 as well as Figure 8As shown, in this embodiment, the upper ends of the two sets of support plates 2 are provided with reinforcing plates 11, and the reinforcing plates 11 are provided with reinforcing plate flanges 12 on both sides. The reinforcing plate flanges 12 are provided with a plurality of reinforcing plate plug welding holes 13. The two sets of reinforcing plate flanges 12 are connected to the corresponding sides of the upper ends of the two sets of support plates 2 through the plurality of reinforcing plate plug welding holes 13. It can be seen that the reinforcing plates 11 are designed with reinforcing plate flanges 12 on both sides, and the reinforcing plate flanges 12 are designed with a plurality of reinforcing plate plug welding holes 13. The reinforcing plates 11 are welded to the middle position of the upper end of the support plate 1 through the plurality of reinforcing plate plug welding holes 13, and the middle of the two support plates 2 are overlapped together. This reduces the amount of outward expansion deformation at the middle position of the two sets of support plates 2 during the stress process, and effectively maintains its structural strength. At the same time, the reinforcing plate flanges 12 are located at the position of minimum height of the support plate 2 through the plurality of reinforcing plate plug welding holes 13, which helps to strengthen the structural strength at this position and avoid the problem of local stress concentration in the support plate 2 during the stress process.

[0028] like Figures 6 to 8 As shown, in this embodiment, the passageway frame connecting plate 3, the side frame connecting plate 4, and the main body of the reinforcing plate 11 are all provided with weight-reducing holes 14. Therefore, the weight-reducing holes 14 reduce the overall mass without reducing the overall structural strength.

[0029] like Figure 5 As shown, in this embodiment, several rib drainage outlets 15 are provided at the lower ends of several rib plates 5, and these rib drainage outlets 15 cooperate with the upper end of the airbag seat plate 1. Therefore, several rib drainage outlets 15 are designed along the overlapping edge of the rib plates 5 and the airbag seat plate 1 to facilitate the unblocking or cleaning of foreign objects on the airbag seat plate 1.

[0030] like Figure 4 As shown, in this embodiment, a plurality of support plate drain outlets 16 are provided at the lower end connection of the support plate 2, and the plurality of support plate drain outlets 16 cooperate with the upper end of the airbag seat plate 1. It can be seen that a support plate drain outlet 16 is designed in the middle of the lower end of the support plate 2 to facilitate the unblocking or cleaning of foreign objects on the airbag seat plate 1.

[0031] like Figure 4 As shown, in this embodiment, the main body of the support plate 2 is provided with a pipeline hole 17, which cooperates with an external pipeline. Therefore, the pipeline hole 17 cooperates with the external pipeline to prevent the external pipeline from falling onto the airbag seat plate 1.

[0032] like Figure 5As shown, in this embodiment, the airbag seat plate 1 has an air tube connector mounting hole 18 in the middle, which is connected to the air tube end of the external control airbag. Therefore, the air tube connector mounting hole 18 is used to install the air tube of the control airbag.

[0033] The working principle of this utility model is as follows: The two sets of support plates 2 are placed vertically and parallel, and the lower connecting end is connected to the upper surface of the airbag seat plate 1. The aisle frame connecting plate 3, the side frame connecting plate 4, and the reinforcing plate 11 are respectively connected to the large end, small end, and upper middle part of the two sets of support plates 2. After the connection is completed, the aisle frame connecting plate 3 is connected to the front mounting position of the frame 19, and the side frame connecting plate 4 is connected to the side frame. After the connection is completed, the air pipe end of the control airbag on the air suspension is connected to the air pipe connector mounting hole 18 to realize the installation and connection of the front airbag seat structure.
