[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] See also Figure 1-Figure 4 , which is a side anti-collision beam structure 100 of a vehicle door provided by the utility model. The side anti-collision beam structure 100 of the vehicle door includes an inner panel 10, a side anti-collision beam 20 fixed on the inner panel 10, and a supplementary bracket 30 fixed between the side anti-collision beam 20 and the inner panel 10; the supplementary bracket 30 includes a mounting portion 31 fixedly connected to the inner panel 10 and a supporting portion 32 extending from the mounting portion 31 away from the inner panel 10 to abut against the bottom of the side anti-collision beam 20; the side anti-collision beam 20 includes a first fixing portion 21 fixed on the inner panel 10 and a second fixing portion 22 fixed on the supporting portion 32, and the tops of the first fixing portion 21 and the second fixing portion 22 extend toward the outer panel 40 to form an anti-collision rib 23. In the side impact test condition, the rigid part hits the outer panel 40 of the door. The supplementary bracket 30 fixed between the second fixing portion 22 of the side impact beam 20 and the inner panel 10 can effectively reduce the distance between the impact rib 23 of the side impact beam 20 and the outer panel 40, thereby effectively filling the buffer space between the outer panel 40 and the inner panel 10, increasing the force buffering area, and making the force transmission good during the whole collision process, thereby effectively improving the side impact resistance of the side impact beam structure 100 of the door. In addition, the front and rear drop of the first fixing portion 21 and the second fixing portion 22 of the side impact beam 20 during hot pressing can be effectively reduced, reducing the absolute stamping depth of the side impact beam 20, thereby effectively reducing the manufacturing difficulty and cost of the side impact beam 20.

[0025] like Figure 2 As shown, in the embodiment provided by the utility model, the supporting portion 32 of the supplementary bracket 30 has a supporting protrusion 321 extending toward the side anti-collision beam 20, and the supporting protrusion 321 is embedded in the anti-collision rib 23 of the side anti-collision beam 20. By embedding the supporting protrusion 321 on the supporting portion 32 of the supplementary bracket 30 in the anti-collision rib 23 of the side anti-collision beam 20, the stability of the second fixing portion 22 of the side anti-collision beam 20 fixed to the supplementary bracket 30 can be effectively improved, and the fit between the second fixing portion 22 of the side anti-collision beam 20 and the supporting portion 32 of the supplementary bracket 30 can be improved, thereby ensuring the positioning accuracy between the second fixing portion 22 and the supplementary bracket 30.

[0026] like Figure 1 and Figure 3As shown, in the embodiment provided by the utility model, the shape of the anti-collision rib 23 is adapted to the shape of the supporting protrusion 321, thereby further improving the fit between the second fixing portion 22 of the side anti-collision beam 20 and the supporting portion 32 of the supplementary bracket 30, and further avoiding the generation of a gap between the second fixing portion 22 of the side anti-collision beam 20 and the supporting portion 32 of the supplementary bracket 30, ensuring good force transmission throughout the collision process, thereby effectively improving the side impact resistance of the side anti-collision beam structure 100 of the vehicle door while preventing the side anti-collision beam 20 from falling off the supporting portion 32.

[0027] like Figure 2 As shown, the support portion 32 of the supplementary bracket 30 is recessed inward and forms a receiving cavity for accommodating the second fixing portion 22 of the side anti-collision beam 20, and the bottom of the second fixing portion 22 fits in the receiving cavity. By fitting the bottom of the second fixing portion 22 in the receiving cavity, the positioning accuracy between the second fixing portion 22 and the support portion 32 of the supplementary bracket 30 can be further improved after the side anti-collision beam 20 is assembled on the supplementary bracket 30, thereby effectively reducing the distance between the anti-collision rib 23 of the side anti-collision beam 20 and the outer panel 40. In addition, in the embodiment provided by the utility model, the width of the second fixing portion 22 gradually increases from the first fixing portion 21 toward the root of the second fixing portion 22, thereby effectively increasing the contact area between the second fixing portion 22 of the side anti-collision beam 20 and the support portion 32 of the supplementary bracket 30.

[0028] like Figure 2 and Figure 3 As shown, since the second fixing portion 22 of the side impact beam 20 in the utility model is welded and fixed to the supporting portion 32 of the supplementary bracket 30, by setting the width of the second fixing portion 22 to gradually increase from the first fixing portion 21 toward the root of the second fixing portion 22, the contact area between the second fixing portion 22 of the side impact beam 20 and the supporting portion 32 of the supplementary bracket 30 can be increased, thereby effectively ensuring the stability of the second fixing portion 22 of the side impact beam 20 and the supporting portion 32 of the supplementary bracket 30 after welding and fixing, and further improving the strength of the welded and fixed connection between the second fixing portion 22 and the supporting portion 32 of the supplementary bracket 30.

[0029] like Figure 1 and Figure 4As shown, the vehicle door has a mounting groove 11 for mounting the supplementary bracket 30, and the supplementary bracket 30 also includes a connecting portion 33 extending from the mounting portion 31 to the top of the mounting groove 11. Through the mounting groove 11 on the vehicle door, the installation position of the supplementary bracket 30 on the vehicle door can be quickly determined and the positioning accuracy of the supplementary bracket 30 on the vehicle door can be effectively improved, thereby improving the convenience of the installation operation of the supplementary bracket 30. In the embodiment provided by the utility model, a plurality of positioning holes 331 are provided on the connecting portion 33. Through the positioning holes 331 on the connecting portion 33, the installation position of the supplementary bracket 30 in the mounting groove 11 of the vehicle door can be further determined, thereby further improving the positioning accuracy of the supplementary bracket 30 installed in the vehicle door. The mounting portion 31 of the supplementary bracket 30 in the utility model includes a first mounting surface 311 that fits the inner wall of the inner panel 10 and a second mounting surface 312 that fits the inner side wall, and the first mounting surface 311 and the second mounting surface 312 are welded and fixed to the inner panel 10. After determining the installation position of the supplementary bracket 30 by means of the installation groove 11 on the vehicle door and the positioning hole 331 on the connecting portion 33 of the supplementary bracket 30, by welding and fixing the first installation surface 311 and the second installation surface 312 of the fixing portion to the vehicle door inner panel 10, a double-sided welding and fixing operation between the supplementary bracket 30 and the vehicle door inner panel 10 can be achieved, thereby effectively ensuring the stability of the supplementary bracket 30 fixed to the inner panel 10 of the vehicle door.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
