[0026] Please also read Figures 1 to 4 , the installation bracket provided by the utility model is now described. The installation bracket 20 is used to be fixed on the inner plate of the A-pillar and install the instrument panel reinforcement beam 10, the inner plate of the A-pillar includes a first limiting surface 101 and a second limiting surface 102, the first limiting surface 101 and the second limiting surface 102 intersect to form an angular space; the installation bracket 20 includes a support plate 21, the two sides of the support plate 21 are respectively provided with a first connection part 201 and a second connection part 202, and the first connection part 201 and the second connection part 202 are both provided with cavities; wherein the first connection part 201 is fixedly abutted with the first limiting surface 101 along the X direction, and the first connection part 201 is fixedly abutted with the second limiting surface 102 along the Y direction, and the second connection part 202 is used to install the instrument panel reinforcement beam 10.

[0027] It should be noted that, in this embodiment, the A-pillar inner plate may be a lower section A-pillar reinforcement plate 30 located at the lower section of the A-pillar, and the reinforcement plate may be a hollow multi-cavity profile, such as Figure 2 As shown, an angular space is set up considering the connection requirements of the dashboard reinforcement beam 10, and the two side walls of the angular space respectively form the above-mentioned first limiting surface 101 and the second limiting surface 102, wherein the first limiting surface 101 is perpendicular to the X direction, and the second limiting surface 102 is perpendicular to the Y direction.

[0028] It should be explained that, in this embodiment, the mounting bracket 20 can be a welded part or an integrally formed casting part. Here, integrally formed by casting is preferred, which is more beneficial to the overall structural strength and stability of the mounting bracket 20.

[0029] Specifically, in the present embodiment, the mounting bracket 20 and the A-pillar inner panel may be connected by placing one side wall of the first connection portion 201 against the first limiting surface 101 and welding it, while placing the other side wall against the second limiting surface 102 and welding it, thereby utilizing the cooperation between the first limiting surface 101 and the second limiting surface 102 and the first connection portion 201 to form a bidirectional abutment limit in the X and Y directions for the mounting bracket 20. Optionally, the above-mentioned welding method adopts MIG (inert gas shielded welding) process.

[0030] Taking into account the needs of disassembly and assembly, the connection method between the dashboard reinforcement beam 10 and the mounting bracket 20 can be to overlap the dashboard reinforcement beam 10 on the second connecting part 202 along the X direction and fix it by screwing. At the same time, considering the installation position accuracy and stability, the dashboard reinforcement beam 10 and the second connecting part 202 can be pinned and positioned.

[0031] It should be understood that the cavities provided in the first connection portion 201 and the second connection portion 202 can be a single-cavity structure or a multi-cavity structure. Of course, considering the structural strength, a multi-cavity structure can be preferably adopted. Furthermore, the first connection portion 201 and the second connection portion 202 located on both sides of the support plate 21 in the Y direction can adopt a partially overlapping manner in the Y direction to improve the Y-direction rigidity of the support plate 21. Specifically, the first connection portion 201 can occupy the upper half of one side of the support plate 21, while the second connection portion 202 occupies the entire area on the other side of the support plate 21, thereby ensuring that an avoidance space is formed between the support plate 21 and the second limiting surface 102 to facilitate the assembly of peripheral parts.

[0032] Compared with the prior art, the mounting bracket provided in the present embodiment can improve the structural strength and rigidity of the mounting bracket 20 itself by setting a cavity structure at the first connecting portion 201 and the second connecting portion 202 on both sides of the support plate 21, and has strong stability, thereby improving the overall modal performance; at the same time, the first connecting portion 201 can also be used to form a two-way abutment limit in the X direction and the Y direction with the first limiting surface 101 and the second limiting surface 102 respectively, thereby increasing the contact area between the mounting bracket 20 and the A-pillar inner plate, which can not only avoid stress concentration, improve the vehicle's X-direction head-on collision performance and Y-direction side collision performance, and thus improve the safety performance of the entire vehicle, but also improve the connection stiffness and mode of the instrument panel reinforcement beam 10, thereby avoiding abnormal noise of the instrument panel caused by vibration excitation when the vehicle is driving on a bumpy road, which is helpful to control driving noise and improve vehicle quality control.

[0033] Please note that Figure 3The first connection part 201 includes a plurality of first baffles 22 spaced apart in the Z direction in the cavity thereof, and the cavity of the first connection part 201 forms a multi-cavity structure based on each first baffle 22. The cavity of the first connection part 201 forms a multi-cavity structure through the plurality of first baffles 22 spaced apart, thereby improving the structural strength and stiffness of the first connection part 201, and further improving the overall modal performance.

[0034] Similarly, if Figure 4 As shown, the second connection part 202 includes a plurality of second baffles 23 spaced apart in the Z direction in the cavity thereof, and the cavity of the second connection part 202 forms a multi-cavity structure based on each second baffle 23. The cavity of the second connection part 202 can also form a multi-cavity structure by utilizing the plurality of second baffles 23 spaced apart inside the cavity thereof, thereby improving the structural strength and stiffness of the second connection part 202, and further improving the overall modal performance.

[0035] Optionally, the first baffles 22 and the second baffles 23 are aligned one by one along the Y direction, thereby further improving the side collision performance of the vehicle body while ensuring the frontal collision performance of the vehicle body.

[0036] It should be understood that in this embodiment, sealing plates 24 are respectively provided at both ends of the support plate 21 in the Z direction, one end of the sealing plate 24 extends toward the second limiting surface 102 and forms the cavity wall of the first connection part 201, and the other end of the sealing plate 24 extends in the opposite direction and forms the cavity wall of the second connection part 202. The cavities of the first connection part 201 and the second connection part 202 are both vertical cavities extending substantially along the Z direction, and the cavity top and bottom walls of the first connection part 201 and the second connection part 202 are formed by respectively providing sealing plates 24 at both ends of the support plate 21 in the Z direction, i.e., the vertical direction. It should be understood that the cavity top and bottom walls of the first connection part 201 and the second connection part 202 are formed based on the same sealing plate 24, thereby ensuring the structural integrity and improving the overall structural strength, stiffness and modal characteristics.

[0037] For some possible implementations, see Figure 3 and Figure 4 The first connecting part 201 includes a first connecting plate 25 and a second connecting plate 26; the first connecting plate 25 and the second connecting plate 26 respectively form one side wall of the cavity of the first connecting part 201; wherein, the first connecting plate 25 is arranged at the end of the support plate 21 facing the first limiting surface 101, and the first connecting plate 25 is abutted and fixed to the first limiting surface 101; the second connecting plate 26 is arranged at the end of the first connecting plate 25 facing the second limiting surface 102, and the second connecting plate 26 is abutted and fixed to the second limiting surface 102.

[0038] The first connecting plate 25, the second connecting plate 26 and the support plate 21 can be integrally formed by a casting process. The end of the support plate 21 forms a groove structure by continuously bending the first connecting plate 25 and the second connecting plate 26. The sealing of the groove by the sealing plates 24 at both ends of the support plate 21 in the Z direction can form a cavity of the first connecting portion 201. On this basis, the first connecting plate 25 is abutted against and welded to the first limiting surface 101, and the second connecting plate 26 is abutted against and welded to the second limiting surface 102, which can increase the connection contact area between the mounting bracket 20 and the A-pillar inner plate to form a bidirectional abutment positioning structure in the X and Y directions, and can also increase the number of connecting welding points or welds, thereby improving the strength and rigidity of the connection structure, and further improving the modal characteristics of the instrument panel reinforcement beam 10.

[0039] Specifically, Figure 4 As shown, in this embodiment, the second connecting portion 202 includes a third connecting plate 27, and the third connecting plate 27 forms one side wall of the cavity of the second connecting portion 202; wherein, the third connecting plate 27 is arranged at the end of the support plate 21 away from the first limiting surface 101, and the third connecting plate 27 is connected to the instrument panel reinforcement beam 10.

[0040] The third connecting plate 27 and the support plate 21 can be integrally formed based on a casting process. Since the bent third connecting plate 27 can form an L-shaped structure with the support plate 21, the sealing plates 24 set at both ends of the support plate 21 in the Z direction can form a cavity of the second connecting portion 202. The cavity is an angular cavity, which can not only improve the structural strength and rigidity, but also the angular structure is conducive to forming an avoidance space, thereby facilitating the installation layout of peripheral parts.

[0041] It should be understood that the above-mentioned first connecting plate 25, second connecting plate 26, third connecting plate 27, each first partition plate 22, second partition plate 23 and two sealing plates 24 are all integrally formed with the support plate 21 using a casting process, that is, the mounting bracket 20 is an integrally cast part, thereby improving the overall structural strength, stiffness and modal performance of the mounting bracket 20.

[0042] Please note that, see Figure 3 The third connecting plate 27 has at least two mounting holes 271 spaced apart along the Z direction, and the mounting holes 271 are used to connect the instrument panel reinforcement beam 10. On the basis of the third connecting plate 27 supporting the instrument panel reinforcement beam 10 in the X direction, the third connecting plate 27 is screwed and fixed to the instrument panel reinforcement beam 10 through at least two mounting holes 271, thereby ensuring the connection stability.

[0043] On this basis, in order to facilitate assembly, projection welding nuts are provided on the plate surface of the third connecting plate 27 facing away from the instrument panel reinforcement beam 10 at positions corresponding to each mounting hole 271. During assembly, it is only necessary to pass each connecting part on the instrument panel reinforcement beam 10 through the mounting holes 271 at the corresponding positions and then screw them together with the projection welding nuts.

[0044] Furthermore, in order to ensure the Y-direction and Z-direction position accuracy and connection stability of the instrument panel reinforcement beam 10, as shown in FIG. Figure 3 As shown, the third connecting plate 27 is provided with an installation positioning hole 272 , and the installation positioning hole 272 is plugged and matched with a positioning pin provided on the instrument panel reinforcement beam 10 .

[0045] Based on the same inventive concept, see Figures 1 to 4 The embodiment of the present application also provides an instrument panel reinforcement beam assembly installation structure, including an instrument panel reinforcement beam 10, two A-pillar lower section reinforcement plates 30, and the two above-mentioned mounting brackets 20; wherein the two A-pillar lower section reinforcement plates 30 each have a first limiting surface 101 and a second limiting surface 102 suitable for fixing the mounting bracket 20, and the two ends of the instrument panel reinforcement beam 10 are respectively connected to the two mounting brackets 20.

[0046] Compared with the prior art, the instrument panel reinforcement beam assembly installation structure provided by the utility model has two ends of the instrument panel reinforcement beam 10 fixedly connected to one of the A-pillar lower reinforcement plates 30 through the above-mentioned installation bracket 20, which can increase the contact area between the installation bracket 20 and the A-pillar lower reinforcement plate 30, not only can stress concentration be avoided, the vehicle's X-direction head-on collision performance and Y-direction side collision performance are improved, thereby improving the safety performance of the entire vehicle, but also the connection stiffness and mode of the instrument panel reinforcement beam 10 can be improved, thereby avoiding abnormal noise of the instrument panel caused by vibration excitation when the vehicle is driving on a bumpy road, which helps to control driving noise and improve vehicle quality control.

[0047] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including the above-mentioned instrument panel reinforcement beam assembly installation structure.
