Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle bracket technology, and in particular to a multifunctional bracket for CNG single-fuel vehicles. Background Technology
[0002] CNG single-fuel vehicles are those that use CNG single-fuel engines, relying entirely on compressed natural gas as fuel. Thanks to its high octane rating, CNG exhibits cleaner combustion, significantly reducing pollutant emissions and fully meeting environmental standards. Existing CNG single-fuel vehicles contain various functional components, including shift cables, fuel lines, gas lines, fuel tanks, fuel pump wiring harnesses, and carbon canisters. These components typically require separate brackets or mounting points in specific locations on the vehicle body, but this decentralized installation method has drawbacks.
[0003] Each component requires a separate bracket and fasteners, increasing the number of parts. Assembly workers need to perform multiple positioning and tightening operations, making the installation process complex, increasing assembly time and labor costs, impacting production cycle time, and reducing efficiency. Multiple independent brackets occupy valuable vehicle body space, especially in compact areas such as the engine compartment and dashboard, making layout difficult. Furthermore, This decentralized installation method has multiple independent installation points, which leads to the accumulation of errors at multiple points and affects the accuracy and consistency of component installation positions. Utility Model Content
[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a multi-functional bracket for CNG single-fuel vehicles, which realizes the integrated installation of multiple functional components in CNG single-fuel vehicles and solves the problems of low efficiency, difficult layout and insufficient accuracy of decentralized installation.
[0005] A multi-functional bracket for a CNG single-fuel vehicle includes a crossbeam assembly, a first side beam, a second side beam, and a support beam assembly. The crossbeam assembly is connected to the fuel tank and has a first lug connected to a shift cable. Both ends of the crossbeam assembly are connected to the first and second side beams, respectively. One end of the support beam assembly is connected to the second side beam, and the other end is connected to the crossbeam assembly. The support beam assembly is connected to the carbon canister. The bracket has several pipe clamps, which are connected to the fuel pump wiring harness and the gas pipeline, respectively.
[0006] By setting up a crossbeam assembly, a first side beam, a second side beam, and a support beam assembly, the fuel tank, shift cable, fuel pump wiring harness, gas pipeline, and carbon canister are integrated and installed on this one-piece multi-functional bracket, which improves assembly efficiency, saves vehicle space, and enhances the accuracy and consistency of component installation.
[0007] Furthermore, the beam assembly includes a first beam and a second beam, which are arranged in parallel.
[0008] The installation of the fuel tank is made more stable by setting up parallel first and second crossbeams.
[0009] Furthermore, the crossbeam assembly has two pairs of second lugs on both sides, and the second lugs are connected to the fuel tank straps.
[0010] By setting two pairs of second lugs to install and connect the fuel tank straps, the installation of the fuel tank becomes more stable.
[0011] Furthermore, the first and second side beams are angled. This angled arrangement makes the bracket layout more suitable for CNG-only vehicles, saving vehicle space.
[0012] Furthermore, the support beam assembly includes a portal-shaped support beam and an upper support beam, and the two support legs of the portal-shaped support beam are respectively connected to the first crossbeam and the second crossbeam; The second side beam has an upper edge and a lower edge. The upper edge is connected to one end of the upper support beam, and the other end of the upper support beam is connected to the portal support beam. The lower edge of the second side beam is connected to the first crossbeam.
[0013] The installation of the carbon canister is made more stable by setting up a support beam assembly.
[0014] Furthermore, the support beam assembly also includes a first inclined support beam and a second inclined support beam. The two ends of the first inclined support beam are respectively connected to one side of the portal support beam and the first crossbeam, and the two ends of the second inclined support beam are respectively connected to the other side of the portal support beam and the upper support beam.
[0015] By setting up the first and second inclined support beams, the support beam group forms a stable triangular structure, which is beneficial for the stable installation of the carbon canister.
[0016] Furthermore, the support beam assembly includes a longitudinal support beam, the two ends of which are connected to the first crossbeam and the second crossbeam, respectively.
[0017] By setting longitudinal support beams to connect the first and second crossbeams, the connection strength of the support structure is improved.
[0018] Furthermore, the bracket is provided with several fixing ears, which are installed and connected to the vehicle body.
[0019] Multiple mounting ears are used to ensure the bracket is stably installed inside the vehicle body.
[0020] Furthermore, a longitudinal support plate is provided on the side of the first side beam away from the crossbeam assembly. By providing a longitudinal support plate to support the oil tank, the connection strength of the bracket is improved.
[0021] Furthermore, the connection points of the various components in the bracket are welded. This eliminates the risk of loosening due to gaps, and the vibration fatigue resistance is improved by more than 40% compared to bolted connections.
[0022] The beneficial effects of this utility model are: This utility model discloses a multi-functional bracket for CNG single-fuel vehicles. By setting up a crossbeam assembly, a first side beam, a second side beam, and a support beam assembly, the fuel tank, shift cable, fuel pump wiring harness, gas pipeline, and carbon canister are integrated into this one-piece multi-functional bracket, ensuring stable and reliable installation. Compared to traditional distributed installations, this bracket improves assembly efficiency, saves vehicle space, and enhances the accuracy and consistency of component installation. The structure can adapt to vertical loads, distributed horizontal forces, and suspended support requirements, while controlling vibration amplitude below 0.2mm under dynamic load scenarios.
[0023] All components of the bracket are welded, eliminating the risk of gaps and loosening. Its vibration fatigue resistance is more than 40% higher than that of bolted connections. Compared with riveted brackets, it reduces weight by 20%-30% and avoids the weakening of material strength caused by rivet holes. Attached Figure Description

[0038] Specifically, the support beam assembly includes a longitudinal support beam 11, the two ends of which are connected to the first crossbeam 1 and the second crossbeam 2, respectively.
