[0026] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0027] As Figures 1 to 2 shown, this embodiment provides a stabilizer bar mounting structure, which includes a mounting structure 1 and a strengthening structure 2. Among them, the mounting structure 1 includes a mounting member 11, a first connecting plate 12 and a second connecting plate 13. The first connecting plate 12 and the second connecting plate 13 are respectively connected to both sides of the mounting member 11. One end of the mounting member 11 is connected to the cross beam 3 of the subframe, and the first connecting plate 12, the second connecting plate 13 and the other end of the mounting member 11 are all connected to the longitudinal beam 4 of the subframe. The mounting member 11 can be connected to the stabilizer bar; the strengthening structure 2 is arranged on the first connecting plate 12 or the second connecting plate 13, and both the cross beam 3 and the longitudinal beam 4 are connected to the strengthening structure 2.

[0028] By using the stabilizer bar mounting structure provided by the present utility model, the first connecting plate 12 and the second connecting plate 13 are respectively connected to both sides of the mounting member 11, and the strengthening structure 2 is arranged on the first connecting plate 12 or the second connecting plate 13, and both the cross beam 3 and the longitudinal beam 4 are connected to the strengthening structure 2. With such an arrangement, the structural strength of the mounting member 11 can be enhanced, thereby improving the connection strength between the stabilizer bar and the mounting member 11, and avoiding the situation that the stabilizer bar and its mounting structure are prone to fatigue damage after long-term work. By using the stabilizer bar mounting structure of the present utility model, the problem that the stabilizer bar mounting structure in the prior art has no corresponding strengthening structure 2 resulting in poor mounting stiffness is effectively solved.

[0029] In some embodiments, the mounting member 11 includes a mounting main board 111 and a first mounting plate 112 and a second mounting plate 113 connected to both ends of the mounting main board 111. With such an arrangement, the first mounting plate 112 can be connected to the longitudinal beam 4, and the second mounting plate 113 can be connected to the cross beam 3, ensuring that the mounting main board 111 is connected to both the cross beam 3 and the longitudinal beam 4, and improving the connection strength of the mounting member 11; at the same time, the first connecting plate 12 and the second connecting plate 13 are respectively connected to both sides of the mounting main board 111, and the mounting main board 111 can be connected to the stabilizer bar.

[0030] Furthermore, as Figure 1 shown, the first mounting plate 112 includes a first plate body 1121 and a second plate body 1122 connected to each other. The first plate body 1121 is connected to the mounting main board 111, and the second plate body 1122 is attached to and connected to the outer wall of the longitudinal beam 4. With such an arrangement, the connection strength between the first mounting plate 112 and the longitudinal beam 4 can be enhanced, thereby improving the mounting stiffness of the mounting member 11 and the overall strength of the structure.

[0031] Optionally, the second plate body 1122 is an arc-shaped plate, which fits against and is connected to the outer wall of the longitudinal beam 4. With this connection method, compared with the structure of vertical bending and then connection, the structural strength is better, stress concentration is avoided, and the strength and fatigue performance are improved.

[0032] In this solution, the thicknesses of the mounting main board 111, the first mounting board 112, and the second mounting board 113 are all 2.5 mm - 3.5 mm. Limiting the thicknesses of the mounting main board 111, the first mounting board 112, and the second mounting board 113 within the above numerical range can reduce the overall mass of the mounting member 11 while ensuring the overall structural strength, achieving the purpose of light weight.

[0033] Among them, the thicknesses of the mounting main board 111, the first mounting board 112, and the second mounting board 113 can be selected according to the actual on-site requirements. The thicknesses of the mounting main board 111, the first mounting board 112, and the second mounting board 113 can be selected as 2.5 mm, 3 mm, 3.5 mm, etc.

[0034] In this embodiment, the mounting main board 111 has a plurality of mounting holes 1111 arranged at intervals. With this setting, the stabilizer bar and the mounting main board 111 can be connected through the mounting holes 1111.

[0035] Specifically, as Figure 2 shown, one of the first connecting plate 12 and the second connecting plate 13 has a weight-reducing hole 121, and the other is connected to the strengthening structure 2. By setting the weight-reducing hole 121 on the first connecting plate 12 or the second connecting plate 13, the weight of the mounting structure 1 is effectively reduced without reducing the performance of the mounting structure 1.

[0036] It should be noted that the setting position of the weight-reducing hole 121 avoids the stress-bearing area of the mounting hole 1111.

[0037] Specifically, the strengthening structure 2 includes a first strengthening plate 21, a second strengthening plate 22, and a third strengthening plate 23 connected in sequence. Among them, the first strengthening plate 21 is connected to the cross beam 3, the second strengthening plate 22 is connected to the first connecting plate 12 or the second connecting plate 13, and the third strengthening plate 23 is connected to the longitudinal beam 4. With such a setting, the connection strength between the mounting structure 1 and the cross beam 3 and the longitudinal beam 4 can be further enhanced.

[0038] In some embodiments, the third strengthening plate 23 has an arc-shaped connecting surface 231. The arc-shaped connecting surface 231 is fitted against and connected to the outer wall of the longitudinal beam 4. With such a setting, the connection strength between the third strengthening plate 23 and the longitudinal beam 4 is enhanced.

[0039] Specifically, the material of the mounting structure 1 is QSTE420TM. Among them, QSTE420TM is a structural steel plate for cold-formed hot-rolled automobiles, which has advantages such as good processing performance and excellent welding performance.

[0040] The advantages of the stabilizer bar mounting structure provided by the present utility model are as follows:

[0041] 1. A weight-reducing hole 121 is provided on the first connecting plate 12, and the boundary of the weight-reducing hole 121 avoids the stress-bearing area of the mounting hole 1111, effectively reducing the weight of the stabilizer bar mounting structure without reducing the performance.

[0042] 2. The second connecting plate 13 does not have a weight-reducing hole 121 and can be used for welding connection with the strengthening structure 2 to further improve the strength of the mounting structure 1.

[0043] 3. The second plate body 1122 in the mounting structure 1 is closely attached to the subframe longitudinal beam 4 through a flanging with an arc transition, strengthening the mounting stiffness of the nearby mounting hole 1111 and the overall strength of the structure. The arc-transition flanging structure adopted here has better strength than the structure of vertical bending and then welding, avoiding stress concentration and improving strength and fatigue performance;

[0044] 4. During the manufacturing process, both the mounting structure 1 and the strengthening structure 2 are realized through a simple welding process, with simple process and low cost.

[0045] This embodiment also provides a vehicle, including a subframe, a stabilizer bar, and the stabilizer bar mounting structure in the above solution. The subframe has a cross beam 3 and a longitudinal beam 4 connected to each other, and the stabilizer bar is mounted on the subframe through the stabilizer bar mounting structure. For the vehicle provided by the present utility model, the first connecting plate 12 and the second connecting plate 13 are respectively connected to both sides of the mounting member 11, and the strengthening structure 2 is arranged on the first connecting plate 12 or the second connecting plate 13. Both the cross beam 3 and the longitudinal beam 4 are connected to the strengthening structure 2. With such an arrangement, the structural strength of the mounting member 11 can be enhanced, thereby improving the connection strength between the stabilizer bar and the mounting member 11, and avoiding the situation that the stabilizer bar and its mounting structure are prone to fatigue failure after long-term work. Using the vehicle of the present utility model effectively solves the problem that the stabilizer bar mounting structure in the prior art has poor mounting stiffness due to the lack of a corresponding strengthening structure 2.

[0046] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly explaining the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
