[0038] like Figure 1-Figure 13 As shown, in this embodiment, fixing brackets 201 are symmetrically installed on both sides of the instrument panel cross beam 1, and the instrument panel cross beam 1 is fixed to the top of the vehicle frame through the body mounting bracket 202. The body mounting bracket 202 is composed of a first mounting bracket 2021 and a second mounting bracket 2022. The first mounting bracket 2021 is fixed above the instrument panel cross beam 1, and the second mounting bracket 2022 is fixed below the instrument panel cross beam 1 to ensure that the cross beam is firmly fixed.
[0039] like Figure 1-Figure 13 As shown, in this embodiment, the body mounting brackets 202 are further connected by a connecting bracket 203, and a front wall bracket 204 is fixed thereto. The connecting bracket 203 and the front wall bracket 204 together form a collision energy absorption and collapse mechanism, which is used to absorb energy during a collision and protect the vehicle and passengers by collapsing. When the vehicle is hit by a collision, the collision energy will be absorbed and dispersed, thereby reducing the impact force on the vehicle body and alleviating the damage caused by the accident.
[0040] like Figure 1-Figure 13 As shown, in this embodiment, a steering column mounting bracket 205 is fixed at a corresponding position below the connecting bracket 203. A steering column positioning point 2051 is provided at the front of the steering column mounting bracket 205 for determining the position of the steering column; a steering column pre-hanging point 2052 is provided on one side of the steering column mounting bracket 205 for pre-installing the steering column. In addition, a welding rib 2053 is provided at the connection between the connecting bracket 203 and the steering column mounting bracket 205 to enhance the strength and stability of the connection.
[0041] like Figure 1-Figure 13 As shown, in this embodiment, the fixing bracket 201 includes a first fixing bracket 2011 and a second fixing bracket 2012. The first fixing bracket 2011 and the second fixing bracket 2012 are formed by a bending process and then welded through corresponding X / Y / Z welding positioning surfaces. Specifically, a guide pin 2013 is installed on one end surface of the fixing bracket 201 through a fixing hole.
[0042] Furthermore, a reinforcing bracket 2014 is provided below the connection between the fixed bracket 201 and the instrument panel cross beam 1, and the reinforcing bracket 2014 is used to improve the modal of the instrument panel cross beam 1, enhance its structural strength, and effectively prevent deformation or vibration of the instrument panel cross beam 1. Specifically, an upper support frame 2015 is connected above the fixed bracket 201, and a lower support frame 2016 is connected below the fixed bracket 201.
[0043] Fixed between the main body mounting brackets 202 are: a floor connecting bracket 206 for connecting the chassis and the body floor to ensure the rigidity and stability of the entire body structure; a main engine reinforcement plate bracket 207 for preventing the main engine from vibrating or loosening during driving; a defrost duct bracket 208 for supporting and fixing the vehicle's defrost duct system; an air-conditioning bracket 209 for installing and supporting the vehicle's air-conditioning system; a glove box bracket 210 for supporting and fixing the vehicle's glove box; and an airbag bracket 211 for installing and fixing the vehicle's safety airbag system.
[0044] like Fig.13 As shown in the figure, the dimensions of modular parts are divided into three categories: fixed dimensions, control dimensions, and variable dimensions. In the specific design, these three dimensions are made into parametric design tables and converted into 3D drawings of parametric copies. The copies are then placed in the company's internal template library. Designers will be prompted to read the modular instructions when calling: According to the requirements of the instructions, fixed dimensions cannot be modified, while control dimensions can be modified within a certain range, and variable dimensions can be flexibly modified according to actual design requirements. Designers can use these parametric copies to generate new designs, avoiding duplication of work, simplifying the design process, and improving the versatility of the beam bracket.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
