[0030] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0031] An embodiment of the present invention provides a front anti-collision beam structure.

[0032] like Figures 1 to 5 As shown, the front anti-collision beam structure comprises: two side anti-collision beams 1 arranged opposite to each other and a middle anti-collision beam 2 arranged between the two side anti-collision beams 1, and each of the side anti-collision beams 1 is fixedly connected to a special-shaped energy absorption box 3, and the special-shaped energy absorption box 3 is used to be fixedly connected to the front longitudinal beam structure;

[0033] Among them, from the first end face to the second end face of the special-shaped energy absorption box 3, the cross-sectional area of ​​the special-shaped energy absorption box 3 gradually decreases, the first end face of the special-shaped energy absorption box 3 is the end face fixedly connected to the side anti-collision beam 1, and the second end face of the special-shaped energy absorption box 3 is the end face fixedly connected to the front longitudinal beam structure.

[0034] In the embodiment of the present invention, the middle anti-collision beam 2 is nested and fixed with the side anti-collision beams 1 on both sides. Optionally, both ends of the middle anti-collision beam 2 are respectively nested in the two side anti-collision beams 1; optionally, one end of the side anti-collision beam 1 is nested in the middle anti-collision beam 2.

[0035] It can be understood that the front anti-collision beam structure described in the embodiment of the present invention adopts a three-section structural design. When a collision occurs, most of the collision energy is absorbed by the middle anti-collision beam 2 and the two side anti-collision beams 1, and part of the collision energy is absorbed by the special-shaped energy absorption box 3. The unabsorbed collision energy is transmitted to the front longitudinal beam structure through the special-shaped energy absorption box 3, thereby improving the safety performance during a frontal collision and reducing personal injury. Moreover, the segmented structure is convenient for replacement after collision damage.

[0036] It should be noted that since the front anti-collision beam structure adopts a three-section structural design, each section can be flexibly combined with different sizes, has a good degree of commonality, achieves a modular design effect, and reduces vehicle development costs.

[0037] It should also be noted that the special-shaped energy absorption box 3 adopts a special-shaped structural design, in which the cross-sectional area of ​​the first end face fixedly connected to the side anti-collision beam 1 is larger than the cross-sectional area of ​​the second end face fixedly connected to the front longitudinal beam structure. When a collision occurs, it can effectively absorb the collision energy and reduce the damage to the vehicle body caused by the impact force. The special-shaped energy absorption box 3 not only improves the passive safety of the automobile, but also reduces the maintenance cost caused by the collision.

[0038] As an optional embodiment, the interior of the special-shaped energy absorbing box 3 is hollow, and the first end surface of the special-shaped energy absorbing box 3 is provided with an opening.

[0039] In an embodiment of the present invention, the interior of the special-shaped energy absorption box 3 is hollow, and an opening is provided on the first end face facing the side anti-collision beam 1. When a collision occurs, the special-shaped energy absorption box 3 collapses to effectively absorb the collision energy and reduce the damage to the vehicle body and the human body caused by the impact force.

[0040] As an optional embodiment, a first connection area 4 is provided at one end of the side anti-collision beam 1, and second connection areas are provided at both ends of the middle anti-collision beam respectively, and the first connection area 4 is connected to the second connection area by bolts.

[0041] like Figure 2 As shown, both ends of the middle anti-collision beam 2 are arranged inside the side anti-collision beam 1 , that is, both ends of the middle anti-collision beam 2 are respectively embedded in the side anti-collision beam 1 .

[0042] Specifically, a first connection area 4 is provided at one end of the side anti-collision beam 1, and second connection areas are respectively provided at both ends of the middle anti-collision beam 2. The second connection area is arranged inside the first connection area 4, and threaded holes are respectively provided at corresponding positions of the first connection area 4 and the second connection area, and the two are fixedly connected by bolts.

[0043] As an optional embodiment, the front anti-collision beam structure further includes:

[0044] The connection interface 5 covers the first connection area 4 and the second connection area, and the connection interface 5 is provided with threaded holes corresponding to the bolt connection positions of the first connection area 4 and the second connection area.

[0045] like Figure 5As shown, in order to strengthen the connection strength between the first connection area 4 and the second connection area and improve the structural strength, a connection interface 5 is used to cover the first connection area 4 and the second connection area in an embodiment of the present invention. Specifically, the connection interface 5 is provided with a threaded hole at a bolt connection position corresponding to the first connection area 4 and the second connection area, and the connection interface 5, the second connection area and the first connection area 4 are fixedly connected by bolts.

[0046] It should be noted that, in order to achieve a modular design effect, the connection interface 5 is standardized and modularized to adapt to the side anti-collision beams 1 and the middle anti-collision beams 2 of different curvatures, lengths, and widths.

[0047] As an optional embodiment, the side anti-collision beam 1 is arc-shaped.

[0048] like Figure 3 As shown, the side anti-collision beam 1 can be made with different curvatures, such as Figure 3 The side impact beams 11, 12 and 13 in the embodiment of the present invention. It is understandable that the side impact beam 1 can also be made of different lengths and widths.

[0049] As an optional embodiment, the middle anti-collision beam 2 is arc-shaped.

[0050] like Figure 4 As shown, the middle anti-collision beam 2 can be made with different curvatures, such as Figure 4 The middle anti-collision beams 21, 22 and 23 in the embodiment of the present invention. It is understandable that the middle anti-collision beam 2 can also be made of different lengths and widths.

[0051] It should be noted that in order to meet the development needs and collision requirements of different vehicle models, technical personnel in this field can flexibly combine the side anti-collision beams 1 with different curvatures, lengths and widths and the middle anti-collision beams 2 with different curvatures, lengths and widths to form the front anti-collision beam structure and achieve a modular design level.

[0052] In summary, the front anti-collision beam structure described in the embodiment of the present invention is used, and the side anti-collision beams 1 and the middle anti-collision beams 2 of various sizes are flexibly combined to realize the application of different vehicle development scenarios, improve the modular level of the front anti-collision beam structure, and connect through the standardized and modular connection interface 5, so as to adapt to different vehicle widths and front overhang lengths, and maximize the adaptation to different front vehicle shapes; at the same time, through the combination form, the development of the types of front anti-collision beam parts is reduced, the development investment is reduced, and the purpose of reducing the cost and increasing the efficiency of the whole vehicle is achieved. Moreover, the safety performance during a frontal collision is improved by the special-shaped energy absorption box 3, and the damage to the vehicle body and the person is reduced.

[0053] An embodiment of the present invention further provides an automobile, comprising the front anti-collision beam structure in the above embodiment.

[0054] The automobile provided by the embodiment of the present invention includes the front anti-collision beam structure as described above. All the above-mentioned front anti-collision beam structure embodiments are applicable to the automobile and can achieve the same or similar beneficial effects, which will not be repeated here.

[0055] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
