What the claims cover, in plain language

Claim 1 - a bracket with a headlamp mounting part for fixing it to the headlamp housing and a locating part for the front bumper. The locating part includes upper support parts on the bracket’s front side that support the bumper vertically, locating it in the Z direction.

Claim 2 - snap parts on the front side that clip into the bumper from above, locating it in the X and Y directions. Claim 3 - the support parts are several support blocks in a row with coplanar support faces. Claim 4 - the snap parts are several snap blocks with downward clamping teeth. Claim 5 - snap blocks and support blocks are staggered. Claim 6 - a reinforcing rib joins each snap block to the body. Claim 7 - a thin-wall body with vertical and horizontal ribs on the back.

This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.

What this means for US production

This patent was filed only in China. It is still in force in China, so making or selling this design in China would need the owner’s permission while it lasts (at most until 2031-10-19). It has no US or other foreign counterpart and does not restrict the design outside China.

Two points to settle early:

  • Other patents may exist. Headlamp and fascia mounting brackets are patented by vehicle makers and lighting suppliers in the US and Europe - this design has itself been cited by later European filings from a carmaker and a lighting supplier - so a freedom-to-operate (FTO) review for the target vehicle should come before tooling.
  • Vehicle-specific geometry. The bracket is designed around one headlamp housing and one bumper flange; CAD data for both is needed to start.

Customization and manufacturing

What can be customized

AreaOptions
GeometryFitted to your headlamp housing and bumper flange from CAD
MaterialPP-T20, PA6-GF30 or PC/ABS, chosen for stiffness and temperature
LocatingNumber and spacing of support and snap blocks; tooth shape
FasteningScrew bosses, clip-on or heat-staked to the lamp
VariantsLeft/right hand, rear-lamp and fascia versions
MarkingPart numbers, material codes, date wheels molded in

Things to plan for (US market)

  • FMVSS 108 - the bracket does not itself emit light, but it must not change the aim or mounting of a headlamp certified to FMVSS 108; aim is checked on the vehicle.
  • 49 CFR Part 581 bumper standard - for passenger cars, bumper-system changes must still meet the low-speed impact requirements.
  • Material identification - plastic parts are normally marked with ISO 11469 material codes for recycling, as most carmakers require.
  • Automaker PPAP - supply to a vehicle maker needs a Production Part Approval Process package and IATF 16949-certified production.

How a project runs

  1. Inquiry - vehicle program, lamp and bumper CAD, volumes.
  2. Design - bracket geometry, block layout, rib structure, mold-flow analysis.
  3. Prototype - 3D-printed or soft-tool parts checked on a vehicle buck for gap and flush.
  4. Pilot run - production-tool parts for PPAP measurement and testing.
  5. Production - volume molding, packaging and delivery to your line.

Quantities & timeline

The bracket needs a steel injection mold - often a family mold for left and right hand - with slides for the snap teeth; checking fixtures are needed for dimensional inspection. Most development time goes into tolerance analysis and gap-and-flush trials. Send us your vehicle program, CAD data, material, annual volume and target price and we will reply with options.
