Description

Technical Field

[0001] This utility model relates to the technical field of commercial vehicle body components, and in particular to commercial vehicle bumper assemblies. Background Technology

[0002] Car bumpers are safety devices that absorb and mitigate external impacts and protect the front and rear of the vehicle. Located in most areas of the front and rear of the car, they are designed to prevent external damage from affecting the vehicle's safety systems and play a very important role in ensuring vehicle safety.

[0003] In the commercial vehicle sector, the design requirements for front bumpers vary significantly among models such as tractor trucks and cargo trucks due to differences in functional positioning and overall vehicle hardpoint layout. Consequently, front bumpers for current commercial vehicle models are mostly independently developed, lacking versatility. This leads to long development cycles, repetitive mold investments, and high repair costs when decorative components or the center bumper are damaged, requiring replacement of the entire bumper assembly.

[0004] Therefore, there is an urgent need for commercial vehicle bumper assemblies to solve the above problems. Utility Model Content

[0040] like Figures 1-8 As shown, in this embodiment, the commercial vehicle bumper assembly includes a general body 1, a middle bumper assembly 2, and a decorative assembly 3. The general body 1 includes a bracket 11, a first bumper 12, and a second bumper 13. The bracket 11 is fixed to the vehicle frame. The first bumper 12 and the second bumper 13 are respectively installed on both sides of the bracket 11, and both the first bumper 12 and the second bumper 13 have fixing holes. The middle bumper assembly 2 includes a central decorative panel 21 and a fixing bracket 22. The central decorative panel 21 is installed on the bracket 11, and the fixing bracket 22 is installed on the central decorative panel 21. The fixing bracket 22 is detachably connected to the bracket 11. The decorative assembly 3 includes a first decorative panel 31 and a second decorative panel 32. The sides of the first decorative panel 31 and the second decorative panel 32 are installed on the central decorative panel 21. Both the first decorative panel 31 and the second decorative panel 32 are provided with sliding nuts 4, which are connected to the fixing holes.

[0041] The general-purpose body 1 covers the core protection area of ​​the front of the vehicle. The first bumper 12 and the second bumper 13 are metal stamping parts. The first bumper 12 and the second bumper 13 are the left and right parts of the bumper, respectively, and are fixed to the bracket 11 with bolts. The lower part of the first bumper 12 and the second bumper 13 is provided with fixing holes for mounting the first decorative panel 31 and the second decorative panel 32. The bracket 11 serves to connect the first bumper 12, the second bumper 13, and the middle decorative panel and fix them to the vehicle frame. The middle bumper assembly 2 is designed according to the hard points and functional requirements of commercial vehicles. The middle decorative panel 21 is fixed to the bracket 11 with bolts and serves to connect the decorative assembly 3 and the general-purpose body 1 to form a complete module. The fixing bracket 22 is connected to the middle decorative panel 21 with bolts. The bracket 11 is provided with fixing points for mounting the fixing bracket 22, which increases the rigidity of the middle decorative panel 21. The first decorative panel 31 and the second decorative panel 32 are equipped with sliding nuts 4. The first decorative panel 31 has a fixing hole. The first bumper 12 is fixedly connected to the fixing hole of the first decorative panel 31 through the sliding nut 4. The intermediate bumper assembly 2, the general body 1, the first decorative panel 31 and the second decorative panel 32 are connected to form a modular bumper assembly. The decorative assembly 3 is detachably connected to the general body 1 through the sliding nut 4. The intermediate bumper assembly 2 is quickly detached and connected to the bracket 11 of the general body 1 through the fixing point of the fixing bracket 22. When the decorative assembly 3 or the intermediate bumper assembly 2 is damaged, only a single module needs to be replaced, reducing maintenance costs. The first decorative panel 31 and the second decorative panel 32 are installed when matching the intermediate bumper assembly 2 of the tractor unit, but not when matching the intermediate bumper assembly 2 of the cargo truck. This satisfies the requirement of the universal body 1 for use between cargo trucks and tractor units, meaning that the bumper assembly of commercial vehicles adopts the universal body 1 design, adapting to the unified installation interface of tractor units and cargo trucks. This achieves low-cost and rapid adaptation of the commercial vehicle bumper assembly, simplifies the production, assembly, and R&D cycle, reduces mold costs, and reduces inventory pressure. Optionally, it is not limited to tractor units and cargo trucks, but also includes other commercial vehicle models.
