Technical scheme of the present invention is as follows:

An automobile steering support installation bracket, including a bracket body in the shape of "几", characterized in that: the upper part of the left side of the bracket body is provided with a through hole, and the lower part of the left side is inclined to the left to form a left The overlapping surface, the lower part of the right side of the bracket body is bent to the right to form a right overlapping surface;

It also includes a bent inner reinforcement, the upper section of the inner reinforcement is vertical, the middle section is bent to the right, and the lower section is bent to the right to form a straight shape; the upper section of the inner reinforcement is provided with a mounting hole, the inner The upper section of the reinforcement is fixedly connected to the upper right side of the left side of the bracket body, the installation hole corresponds to the through hole, and the inner reinforcement can disperse the force in the vertical direction of the steering support installation point.

Furthermore, a projection welding nut is provided on the right side of the upper section of the internal reinforcement, and the centerline of the projection welding nut coincides with the centerline of the installation hole, so as to improve assembly reliability and facilitate disassembly and replacement.

Further, a left positioning hole is provided on the left part of the top surface of the support body, and a right positioning hole is provided on the right part of the top surface of the support body; the left positioning hole and the right positioning hole ensure the forming and welding of the support body Fitting precision while also serving as a fixing point for electrical wiring harnesses and interior control boxes.

Further, the lower section of the internal reinforcement is located on the same level as the right overlapping surface of the bracket body.

Further, a first weight-reducing hole is provided in the middle of the right side of the bracket body to reduce the weight of the bracket body while ensuring the strength of the parts.

Further, a second weight-reducing hole is provided in the middle of the top surface of the bracket body to reduce the weight of the bracket body while ensuring the strength of the parts.

Further, a plug welding hole is provided on the lower section of the internal reinforcement, and the plug welding hole can also be used as a positioning hole for the reinforcement on the mold and fixture.

The present invention has the following advantages: since there is an inner reinforcing member fixedly connected to the inside of the bracket body, the strength of the mounting bracket itself is improved, so that the force of the steering support in the vertical direction can be effectively transmitted along the bracket body and the inner reinforcing member On the vehicle body, it can also absorb the vibration force transmitted from the vehicle body to the installation point under the steering support, which reduces the influence of the vibration of the vehicle body on the steering support, and at the same time, the structure of the present invention is simple.

detailed description

Below in conjunction with accompanying drawing, the present invention is described in further detail:

Referring to a kind of automobile steering support mounting bracket shown in Fig. 1 to Fig. 4, it includes a bracket body 1 in the shape of "几", the upper part of the left side of the bracket body 1 is provided with a through hole 13, and the left side The lower part of the bracket body 1 is inclined to the lower left to form a left overlapping surface 16, and the lower part of the right side of the bracket body 1 is bent to the right to form a right overlapping surface 17; it also includes a bent inner reinforcement 2, the inner reinforcement The upper section 24 is vertical, the middle section 25 is bent to the right, and the lower section 26 is bent to the right to be straight; the upper section 24 of the inner reinforcement is provided with a mounting hole 23, and the upper section 24 of the inner reinforcement is connected to the bracket The upper right side of the left side of the main body 1 is fixedly connected, and the installation hole 23 corresponds to the through hole 13 .

A projection welding nut 3 is provided on the right side of the upper section 24 of the inner reinforcement 2 , and the centerline of the projection welding nut coincides with the centerline of the installation hole 23 .

A left positioning hole 12 is provided on the left top surface of the support body 1 , and a right positioning hole 11 is provided on the right top surface of the support body 1 .

The lower section 26 of the internal reinforcement is located on the same level as the right overlapping surface 17 of the bracket body 1 .

A first lightening hole 15 is provided in the middle of the right side of the bracket body 1 .

A second lightening hole 14 is provided in the middle of the top surface of the bracket body 1 .

Plug welding holes 21 and 22 are provided on the lower section 26 of the inner reinforcement member 2 .

The use method of the present invention is as follows: the left lap surface 16 of the bracket body 1 is welded to the left side wall of the floor central channel 4, the right lap surface 17 of the bracket body 1 is welded to the top surface of the floor central channel 4, and the inner reinforcement The lower section 26 of 2 is welded to the top surface of the floor central channel 4 through the plug welding holes 21, 22, and the lower part of the steering support pipe beam column 5 of the steering support is fixed to the mounting bracket through the cooperation of the connecting bolt 6 and the projection welding nut 3 .
