[0028] like Figures 1-4 As shown, a large mesh front bumper with a welding bracket includes a bumper body 1 and a connecting component 2, wherein the connecting component 2 is located at the rear of the bumper body 1.

[0029] The bumper body 1 includes an upper bumper 11 and a lower bumper 12, which are connected by a support column. Side bars are provided on both sides of the upper bumper 11 and the lower bumper 12.

[0030] Reference Figure 1-4 Both the upper bumper 11 and the lower bumper 12 are laterally extended curved tubular components, forming an approximately horizontal beam structure. The upper bumper 11 and the lower bumper 12 are parallel in longitudinal section, with a certain height gap between them to meet the overall buffer space requirements of the bumper.

[0031] Reference Figure 2 The upper bar 11 and the lower bar 12 are spaced a certain distance apart, and the bottom of the upper bar 11 is inclined outwards by a certain distance. The top of the upper bar 11 is parallel to the lower bar 12. The inclined part of the upper bar 11 can disperse the impact when it is subjected to impact. The lower bar 12 is positioned above the upper bar 11. The upper bar 11 and the lower bar 12 form an integrated frame through support columns.

[0032] In this embodiment, stainless steel mesh is installed inside the upper baffle 11 and lower baffle 12, and stainless steel mesh is also installed inside the side bars on both sides of the upper baffle 11 and lower baffle 12. The side bars are set at a certain angle to the upper baffle 11 and lower baffle 12, which is similar to the curvature of the front edge of the car door, which can protect the sides of the front of the car and the vehicle frame. The side bars can disperse the impact force when the vehicle encounters a side collision and ensure that the sides of the front of the car do not directly contact obstacles.

[0033] The stainless steel mesh can be bolted to the upper bar 11 and lower bar 12, providing wind and stone protection. The mesh fits snugly against the bars 11 and 12, preventing cuts from the edges, and it remains securely in place even under vibration or minor impact. The surface of the mesh has a number of holes to ensure unobstructed airflow and to block debris such as stones and branches, preventing foreign objects from directly entering the heat dissipation area.

[0034] The connecting component 2 is located at the rear of the bumper body 1, and can connect and fix the bumper body 1 to the vehicle body. The connecting component 2 includes a support block 21, a connecting block 22, and a locking block 23. The various parts are connected by bolts, realizing modular installation and facilitating installation and disassembly.

[0035] Reference Figure 3 , Figure 4 The support block 21 is an L-shaped plate, with multiple through holes for mounting bolts 3 arranged on one side. Similarly, through holes are arranged at the bottom of the support column, allowing multiple bolts to be installed within them, thus positioning the support block 21 at the bottom of the support column.

[0036] A single screw hole is provided on the top of the other side of the support block 21, and a screw hole is also provided on the bottom of the locking block 23. The support block 21 and the locking block 23 can be connected and fixed by bolts. A protrusion 211 is provided on the top of the side of the support block 21 where the screw hole is provided. The protrusion 211 can provide a constraint during the cooperation of the connecting block 22, the support block 21, and the locking block 23, and limit the position of the connecting plate 222 of the connecting block 22.

[0037] The locking block 23 is flat in shape. A recess 231 is provided on the top of the locking block 23 and a screw hole is provided on the bottom of the locking block 23. The bolt 3 can connect the locking block 23 to the support block 21. The locking block 23 is located inside the support block 21. The width of the locking block 23 is close to the width of the inner side of the support block 21. The locking block 23 does not shift when it is located inside the support block 21.

[0038] The depth of the recess 231 of the locking block 23 is half the width of the locking block 23. The depth of the recess 231 is slightly greater than the height of the connecting plate 222 of the fixing block 221. When connected, the connecting plate 222 can be fixed inside the recess 231.

[0039] The bottom of the connecting block 22 is bent laterally, and the bent part is the connecting plate 222. A groove 2221 is provided at the end of the connecting plate 222. The depth of the groove 2221 is the length of the protrusion 211, and the width of the groove 2221 is the sum of the thickness of the locking block 23 and the thickness of the protrusion 211.

[0040] A hole is provided on the side of the connecting block 22, which can connect to the fixing block 221. A boss is provided at one end of the fixing block 221, which can mate with the hole on the side of the connecting block 22, so that the connecting block 22 is positioned on the side of the fixing block 221. In this embodiment, a screw hole is provided on the surface of the fixing block 221. When the bumper body 1 is installed on the front side of the car, the screw hole of the fixing block 221 can be connected to the car by bolts 3.

[0041] At least one connecting rod 223 is provided on the top of the connecting block 22. In this embodiment, there are two connecting rods 223, which are parallel to the connecting block 22. The connecting rods 223 are bolts, and threaded holes are provided on the vehicle body for connecting to the connecting rods 223. The connecting rods 223 can pass through the threaded holes on the vehicle body and be fixed to the front side of the vehicle body. Both ends of the connecting rods 223 are fixed to the connecting block 22 by bolts.

[0042] In this embodiment, the bolt 3 is installed between the support block 21 and the support column. Multiple screw holes are arranged on the contact side of the support column and the support block 21, and the bolt 3 is installed in the holes to connect the support block 21 and the support column.

[0043] A single screw hole is provided at the connection between the support block 21 and the locking block 23. The bolt 3 can connect and fix the support block 21 and the locking block 23 to ensure that the locking block 23 and the support block 21 do not shift.

[0044] In this embodiment, the connection points of the support block 21, the connecting block 22, and the locking block 23 are fixed by welding.

[0045] In this embodiment, two connecting components 2 are provided, symmetrically arranged on both sides of the bumper body 1. The specific installation steps are as follows:

[0046] 1. Place the connecting block 22 on the front side of the vehicle and fix the connecting block 22 using the connecting rod 223.

[0047] 2. Set the fixing block 221 on the connecting block 22, and connect the vehicle to the fixing block 221 with bolts 3.

[0048] 3. Connect the support block 21 and the locking block 23 by bolt 3 at the connection point. Place the recess 231 of the locking block 23 into the groove 2221 of the connecting plate 222. The recess 231 can accommodate the connecting plate 222, and the groove 2221 can accommodate the locking block 23 and the protrusion 211.

[0049] After assembly, the gaps at the joints of the support block 21, connecting block 22, and locking block 23 are reinforced by welding.

[0050] 4. The bottom of the support column is connected to the side of the support block 21 and fixed with multiple bolts 3. The lower bar 12 is assembled at the bottom of the support column, and the upper bar 11 is assembled after the lower bar 12 is assembled.

[0051] 6. Weld side bars to the sides of the upper bar 11 and lower bar 12 to ensure that there is no obvious misalignment between the side bars and the upper bar 11 and lower bar 12, and that the surface after welding is flat.

[0052] 7. Stainless steel mesh is installed inside the lower bar 12 and the upper bar 11. Ensure that the stainless steel mesh is inside the upper bar 11 and the lower bar 12. Stainless steel mesh is also installed inside the side bars of the upper bar 11 and the lower bar 12.

[0053] In this embodiment, the upper bumper 11 and the lower bumper 12 are connected by a support column. When the front of the vehicle collides, the impact force can be transmitted to the whole vehicle through the connecting component 2, reducing the impact on the engine compartment and the passenger compartment during the collision and improving the overall safety performance of the vehicle.

[0054] The connecting component 2 is divided into a support block 21, a connecting block 22, and a locking block 23. The connecting components 2 are connected by bolts. The position of each module can be adjusted according to different vehicle models to adapt to different vehicle models.

[0055] During maintenance, only the bolts need to be tightened; after disassembly and inspection, only a limited number of bolts 3 need to be loosened. The support block 21, connecting block 22, and locking block 23 are locked together and then welded into a single unit. When subjected to a large impact, the welded joints will not be too tight, and the support block 21, connecting block 22, and locking block 23 can disperse and distribute the impact.

[0056] If the front bumper is slightly impacted during vehicle operation, it is only necessary to check whether the bolt 3 between the support block 21 and the support column is loose; whether the bolt between the locking block 23 and the support block 21 is loose; and whether the connection between the connecting rod 223 and the vehicle body is loose. If any looseness is found, simply use a wrench to tighten it to the fixed torque.

[0057] When the stainless steel mesh ages, corrodes, or is damaged and needs to be replaced after prolonged use, only a portion of the stainless steel mesh needs to be replaced. Simply remove the old mesh and fix the new mesh in place; there is no need to disassemble the bumper body 1.

[0058] Compared to traditional bumpers, this embodiment can transfer the impact to the vehicle body when subjected to a smaller impact, thus preventing deformation; during installation, the assembly of connecting component 2 facilitates overall installation.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model.
