[0038] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and the specific implementation manners.

[0039] Embodiment:

[0040] As Figure 1 shown, the embodiment of the present application discloses an integrated fixed bracket for centrally supporting an airbag and a shock absorber, and its specific structure includes: a support plate 1, a mounting plate 2, two reinforcing bands 3, and a diagonal bracing plate 4.

[0041] The support plate 1 has a concave structure and includes: a fitting plate 11 and two side plates 12; wherein the fitting plate 11 is vertically arranged; the two side plates 12 are vertically arranged and are arranged on both sides of the fitting plate 11.

[0042] Preferably, the support plate 1 is a bent plate, which integrally forms the fitting plate 11 and the two side plates 12. This avoids multiple processing, thereby improving production efficiency, reducing the use of connection methods such as welding, and enhancing the strength and durability of the product.

[0043] The mounting plate 2 is horizontally arranged, with a first mounting hole 21 opened on its top surface. It is arranged between the two side plates 12 and is connected to the fitting plate 11. The mounting plate 2 is rectangular and fixed by welding, thereby increasing the connection area with the fitting plate 11 and the side plates 12, reducing stress concentration, and enhancing the structural strength and load-bearing capacity.

[0044] Two reinforcing bands 3 are arranged on the top surface of the mounting plate 2. One end of each reinforcing band is connected to the fitting plate 11, and the other end is respectively connected to one side plate 12. The reinforcing band 3 is in an L-shaped structure and fixed by welding, thereby expanding the connection area with the mounting plate 2, reducing stress concentration, and enhancing the structural strength and connection stability.

[0045] Preferably, the top surface of the reinforcing band 3 is flush with the top surface of the support plate 1, thereby extending the connection area with the support plate 1, reducing stress concentration, and enhancing the structural strength and connection stability.

[0046] The diagonal brace plate 4 includes: an inclined plate 41 and two support plates 42. Among them, the inclined plate 41 is horizontally arranged, located on the outer side surface of any one side plate 12, with a second mounting hole 411 opened on its top surface, and the height of the side away from the side plate 12 is lower than that of the other side. The two support plates 42 are vertically arranged and located on both sides of the bottom of the inclined plate 41 and are connected to the adjacent side plate 12.

[0047] In the above technical solution, the support plate 1 integrates the mounting plate 2 and the diagonal brace plate 4 and is installed on the vehicle frame, thus becoming the main force-bearing component of the airbag and shock absorber, used to bear the forces generated by the airbag and shock absorber during the operation of the whole vehicle.

[0048] When the bracket is installed, the fitting plate 11 of the support plate 1 is attached to and welded to the longitudinal grid section of the vehicle frame body, thereby transmitting the forces of the airbag and shock absorber to the longitudinal grid section of the whole vehicle, improving the load-bearing capacity of the bracket, and ensuring stable connection.

[0049] When the airbag is installed, its top surface is attached to the mounting plate 2 and connected through a bolt assembly and the first mounting hole 21, thus installed on the bottom surface of the mounting plate 2 and placed inside the support plate 1, obtaining a semi-surrounding protection and reducing the damage probability during use.

[0050] It can be understood that by setting two reinforcing bands 3, the connection stability among the fitting plate 11, the side plates 12, and the mounting plate 2 is strengthened, the stress concentration in the connection area is dispersed, and the structural strength and stiffness of the bracket are further enhanced.

[0051] When the shock absorber is installed, since the shock absorber has a rod-shaped structure, is inclined, and its axis is perpendicular to the inclined plate 41, its top end extends into the inner side of the diagonal brace plate 4 from below, and then is connected through the bolt assembly and the second mounting hole 411, so as to be installed on the bottom surface of the inclined plate 41, thereby obtaining a stable inclined support.

[0052] It can be understood that by providing two support plates 42, the inclined plate 41 is supported, the stress concentration in the connection area between the inclined plate 41 and the side plate 12 is reduced, the load-bearing capacity is improved, and the risk of fracture is reduced.

[0053] Through the above settings, the airbag and the shock absorber can be centrally fixed on the same bracket, so that the fixing position can be accurately controlled, thereby reducing the assembly difficulty, having the advantages of high structural strength and stiffness, improving the reliability, reducing the risk of the welding beam breaking, having good generalization, being suitable for batch and large-scale production and spare parts, and having good actual use effects.

[0054] In some embodiments, as Figures 1 to 2 shown, the support plate 42 is triangular, and its length gradually decreases from top to bottom. It effectively enhances the structural stability, can ensure that the structure is not easily deformed or collapsed when subjected to external forces, and can resist bending and tipping. It can also achieve a better load distribution, making the structural load distribution more uniform, thereby reducing the stress concentration phenomenon and improving the overall load-bearing capacity of the structure.

[0055] Based on the above embodiments, as Figure 1 shown, the diagonal brace plate 4 is a bent plate, which is convenient for production and processing, has low manufacturing cost, and has high stability and durability; there is an arc transition 43 between the inclined plate 41 and the support plate 42, which can disperse stress, make the stress distribution more uniform, avoid generating high stress at the bending place, thereby improving the overall strength and toughness.

[0056] In some embodiments, as Figure 1 and Figure 3 shown, a plurality of drain holes 22 are provided on one side of the mounting plate 2 close to the fitting plate 11.

[0057] By providing the drain holes 22, the accumulated water on the top surface of the mounting plate 2 can be conveniently discharged, avoiding the residue of accumulated water, preventing the plate parts from being corroded or rusted, ensuring the strength and durability of the plate parts, and extending the service life.

[0058] In some embodiments, as Figure 1 and Figure 2 shown, a welding through hole 111 is provided in the middle of the fitting plate 11, and a plurality of welding through grooves 112 are provided on the periphery of the fitting plate 11.

[0059] Preferably, the welding through-hole 111 is circular, the welding through-groove 112 has a linear structure, and both ends are semi-circular without sharp corners, thus avoiding stress concentration at the corners and ensuring the structural strength of the fitting plate 11.

[0060] Through the above settings, welding can be performed on the inner sides of the welding through-hole 111 and the welding through-groove 112, thereby increasing the connection area between the fitting plate 11 and the longitudinal grid section of the vehicle frame body, improving the connection stability, enhancing the load-bearing capacity, and ensuring the support effect.

[0061] In some embodiments, as Figure 1 and Figure 3 shown, the side of the mounting plate 2 away from the fitting plate 11 has an extension area 23, and the extension area 23 is located outside the support plate 1; the extension area 23 preferably has an isosceles trapezoidal shape with a gradually shrinking width, thereby improving the structural compactness and avoiding interference with the arrangement of other components. However, it is not limited to this, and it can also be bow-shaped without specific limitation.

[0062] By setting the extension area 23, on the one hand, the mounting plate 2 can fully cover the top surface of the airbag, thereby improving the protection and covering effect. On the other hand, a vehicle frame connection beam can be added to the mounting plate 2 to further enhance the strength of the bracket.

[0063] In some embodiments, as Figure 4 shown, the side plate 12 includes a support section 121, a transition section 122, and a limit section 123 connected in sequence from top to bottom. The mounting plate 2 is disposed between the support sections 121, and the length of the transition section 122 gradually decreases from top to bottom.

[0064] Through the above settings, while ensuring the structural strength, the material usage is reduced, the lightweight design is achieved, thereby reducing the production cost and reducing the weight of the whole vehicle.

[0065] In the description of the present utility model, a large number of specific details are illustrated. However, it can be understood that the embodiments of the present utility model can be practiced without these specific details. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this specification.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
