What the claims cover, in plain language

Claim 1 - A motorcycle storage box fixed to the frame, comprising a box body and a rotatable box cover. A torsion spring is sleeved on the rotation center of the cover, with one end connected to the box body and the other to the cover. The end of the cover away from the spring carries a lock hook. An electromagnetic lock is fixed to the box body and has a deadbolt that engages the lock hook.

Claim 2 - A connecting plate is fixed to the cover and rotatably attached to the box body; the torsion spring sits on the plate’s rotation center, which is located inside the box. Claim 3 - The connecting plate has a flat part contacting the cover’s lower surface and a bent part curving into the box. Claim 4 - The electromagnetic lock is powered by the electric motorcycle’s battery and wired to a button switch on the handlebar. Claim 5 - The torsion spring end of the cover is positioned near the front of the motorcycle. Claim 6 - The box bottom has U-shaped clamps that fit over discs on the frame, plus a receiving plate bolted to the frame at the opposite end. Claim 7 - A felt lining is bonded inside the box. Claim 8 - A sealing strip on the cover is pressed between the cover and the box body when closed. Claim 9 - A limit stop bar on the cover extends into the box to restrict opening angle. Claim 10 - The cover comprises an inner plate and an outer plate, with the lock hook fixed to the inner plate.

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 and is currently in force. It has no US or other foreign counterpart, so it does not restrict manufacturing or sales in the United States. However, making or selling this exact design in China needs the owner’s permission while the patent remains active.

Two points to settle early:

  • Other patents may exist. Motorcycle luggage, top cases, and electronic locking mechanisms for vehicles are covered by numerous US and international patents held by major powersports accessory makers. A freedom-to-operate (FTO) review focusing on the electromagnetic latch, handlebar switch integration, and hinge geometry is recommended before tooling.
  • Electrical integration. The lock operates on the vehicle’s battery voltage. The wiring harness, switch rating, and lock coil must match the specific motorcycle or scooter platform’s electrical architecture.

Customization and manufacturing

What can be customized

AreaOptions
DimensionsInternal volume and external footprint to be confirmed in design based on target vehicle models
MaterialsBox body and lid in injection-molded ABS, PP, or PC/ABS blends
Lock voltage12V or other voltages to match the host vehicle’s electrical system
LiningFelt, EVA foam, or molded rubber inserts
FinishPainted, textured mold finish, or wrapped surfaces
MountingU-clamp spacing and receiving plate hole patterns adapted to specific frame rails
Switch typeHandlebar push-button, toggle, or integrated into existing control clusters

Things to plan for (US market)

  • FCC Part 15 - If the electromagnetic lock circuit or any added wireless receiver emits radio frequency energy, FCC rules apply.
  • UL or equivalent testing - Electrical components powered by vehicle batteries should meet relevant safety standards for automotive/motorcycle electronics to satisfy US distributors.
  • DOT / state helmet laws - If marketed specifically as a helmet storage box, dimensions must accommodate DOT-approved helmet sizes common in the US market.

How a project runs

  1. Inquiry - Vehicle compatibility, required volume, electrical specs, and target quantities.
  2. Design - 3D modeling of the box, lid plates, connecting plate geometry, and lock placement; wiring schematic.
  3. Prototype - CNC machined or 3D-printed enclosure with off-the-shelf electromagnetic locks for fit and function checks on the actual motorcycle frame.
  4. Pilot run - Injection molds opened; samples tested for lid cycle life, seal compression, lock retention force, and weather resistance.
  5. Production - Molding, felt bonding, seal installation, lock wiring, and final assembly.

Quantities & timeline

Injection molds are required for the box body, inner and outer lid plates, and the connecting plate. The electromagnetic lock may be sourced as a standard component or custom-built depending on voltage and size requirements. Certification tests for electrical safety and environmental sealing take additional time once pilot samples are ready. Send us your target vehicle models, required internal dimensions, electrical specifications, estimated quantity and we will reply with options.
