DETAILED DESCRIPTION

[0023] The specific embodiments of the present application are further described in detail below with reference to the drawings, and the purpose is to help the technical personnel in the field to have a more complete, accurate and in-depth understanding of the inventive concept and technical scheme of the present application, and to help its implementation.

[0024] As shown in the drawings, Figures 1 to 4 The front bumper assembly mounting structure includes a vehicle body sheet metal 2 and a front bumper body 1. The vehicle body sheet metal 2 is provided with a cross beam 3 in the middle, and is provided with a mounting rod 4 at the bottom. The vehicle body sheet metal 2 is provided with a connecting bracket 5 on both sides. The upper end of the front bumper body 1 is connected with the cross beam 3, the bottom of the front bumper body 1 is connected with the mounting rod 4, and the two sides of the front bumper body 1 are connected with the connecting bracket 5. The two sides and the upper and lower ends of the front bumper body 1 are connected on the vehicle body sheet metal 2 to form multiple position connections, improving the connection effect and ensuring that the front bumper body 1 is tightly combined with the vehicle body, reducing vibration and displacement, thereby improving its stability and safety. The mounting rod 4 connects the bottom ends of the vehicle body sheet metal 2, has strong collision energy absorption effect, and uses the mounting rod 4 instead of the traditional mounting bracket, which is conducive to reducing the cost and the weight of the vehicle body.

[0025] As shown in the drawings, Figures 2 to 4 The upper end of the front bumper body 1 is provided with a first connecting bolt 6, and the first connecting bolt 6 is connected with the cross beam 3. The bottom of the mounting rod 4 is provided with a connecting plate 10, and the connecting plate 10 is provided with a nut 11 in the middle. The bottom end of the front bumper body 1 is provided with a second connecting bolt 7, and the second connecting bolt 7 is connected with the nut 11. The two sides of the front bumper body 1 are provided with a third connecting bolt 8. The cross beam 3 and the connecting bracket 5 are both provided with mounting holes for cooperation with the bolts. The first connecting bolt 6 is connected with the mounting hole on the cross beam 3, and the third connecting bolt 8 is connected with the mounting hole on the connecting bracket 5. The connection between the front bumper body 1 and the vehicle body sheet metal 2 is achieved by screwing, which can speed up the assembly rate on the production line, facilitate maintenance and replacement, and improve production efficiency. The bolt connection can provide sufficient strength and stability, and at the same time, the bolt connection allows a certain degree of deformation and displacement during design, which helps to disperse and reduce the impact force of the vehicle body during the collision process, thereby improving the driving safety performance. The above-mentioned bolts are all distributed at the edge position of the front bumper body 1, and will not interfere with other components on the front bumper body 1. The installation direction of the second connecting bolt 7 is the connection in the Z direction of the vehicle body coordinate system, which further improves the connection stability.

[0026] As shown in the drawings, Figure 3As shown, the body sheet metal 2 and the mounting rod 4 are connected with the connecting seat 9 at both ends, the upper end of the connecting seat 9 is detachably connected with the body sheet metal 2, and the end of the connecting seat 9 and the end of the connecting plate 10 are both welded and fixed on the mounting rod 4. The upper end of the connecting seat 9 is provided with a pair of connecting holes, which are connected with the body sheet metal 2 through bolts, so that the mounting rod 4 has a detachable effect, facilitating replacement. When assembling, the mounting rod 4 can be installed by only fastening both ends. The connecting seat 9 and the connecting plate 10 are both welded and fixed on the mounting rod 4, realizing the integral installation of the mounting rod 4, so that the welding process is not required during the assembly of the whole vehicle, which is beneficial to improve the assembly efficiency and shorten the assembly time.

[0027] As shown in Figure 4 and Figure 5 shown, the connecting plate 10 is arranged at equal intervals at the bottom of the mounting rod 4, and the connecting seat 9 and the connecting plate 10 are both U-shaped structures. The connecting seat 9 is designed in a U shape, which is helpful for supporting and stabilizing the bumper, better bearing and buffering the impact force from the outside when the vehicle collides, protecting the safety of the people inside the vehicle and improving the safety performance of the vehicle. The connecting plate 10 is designed in a U shape, which provides space for the cooperation of the bolt and the nut 11.

[0028] As shown in Figure 6 , the second connecting bolt 7 is located at the inner side of the bottom of the front bumper body 1, and the second connecting bolt 7 is provided with a fastening screw 12 at both sides. The position of the second connecting bolt 7 realizes the Z-direction connection between the front bumper body 1 and the body sheet metal 2, and does not affect the appearance of the vehicle body. The fastening screw 12 is adopted, which further improves the connection strength of the bottom structure of the front bumper body 1 and the body sheet metal 2.

[0029] As shown in Figure 3 , the first connecting bolt 6 and the second connecting bolt 7 are arranged at equal intervals. Multiple bolts are arranged to provide connection to achieve uniform connection effect.

[0030] As shown in Figure 5 , the connecting seat 9 is formed by bending, and the bending part of the connecting seat 9 is provided with an anti-rebound rib 15. The connecting seat 9 is bent into a U shape, and the bending part is provided with an anti-rebound rib 15, which is helpful to maintain its shape and ensure its reliable crash energy absorption function. The mounting rod 4 is a circular tube structure, which is beneficial to disperse the impact force by deformation when it is subjected to impact. Its material cost is low, and its both ends are bent to adapt to the arched body.

[0031] As shown in Figure 2 , the front bumper body 1 is provided with a plug cover 13. The plug cover 13 is located on one side of the grille 14, and the plug cover 13 prevents the front part of the vehicle body from being damaged when impacted at low speed, to a certain extent, protects the vehicle from being damaged, and the plug cover 13 seamlessly matches the lines of the vehicle body, which is helpful to the overall appearance of the vehicle.

[0032] The front bumper assembly mounting structure is rationally designed in the connecting position of the front bumper, is fixedly installed on the vehicle body through bolts and screws, the mounting mode of adopting the traditional mounting bracket is cancelled, the collision energy absorption effect is improved, the assembly difficulty is reduced, the production efficiency is improved, the application cost is low, the weight is reduced by 30%-40% compared with the same type bumper, and the design requirements of vehicle lightening are met.

[0033] The utility model is described exemplarily above in combination with the drawings. Obviously, the utility model is not limited by the above mode in the specific implementation. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the above concept and technical scheme of the utility model are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
