What the claims cover, in plain language

Claim 1 - an LED light box billboard comprising a cabinet, first hydraulic cylinders, second hydraulic cylinder, metope (wall plate), and third hydraulic cylinder. The key structural feature is that the bottom of the cabinet offers a limiting slot with a through-hole at its bottom. The first hydraulic cylinders are mounted at the top sides of the cabinet’s inner cavity, with piston bars passing through the cabinet bottom to connect to the LED billboard. The second hydraulic cylinder is on the left side wall. The third hydraulic cylinder is used to adjust the angle via a piston rod connected to a casing and pendant. The claim emphasizes the specific arrangement of these hydraulic components and the mounting slots/holes that allow for the “easy-to-mount” and adjustable functionality described.

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 has lapsed due to non-payment of fees. It no longer restricts anyone in China either. It has no US or other foreign counterpart.

Two points to settle early:

  • Other patents may exist. Outdoor advertising structures and self-cleaning displays are competitive fields. Major signage companies and tech firms hold patents on various hydraulic lifts, magnetic mounts, and automated cleaning systems. A freedom-to-operate (FTO) review is recommended to ensure your specific configuration of hydraulics and brushes does not infringe on active US patents in the signage sector.
  • Mechanical Complexity. Integrating hydraulic cylinders into a consumer-facing retail display introduces leak risks and maintenance requirements. US buyers may prefer simpler mechanical adjustments unless the auto-clean benefit is clearly marketed.

Customization and manufacturing

What can be customized

AreaOptions
SizePanel dimensions and cabinet depth per ad format
HydraulicsSingle vs. double acting cylinders; manual pump vs. electric actuator
Brush MaterialSoft bristles for acrylic/glass; stiffer for rugged surfaces
MountingWall bracket style; pole mount adapter options
ControlTimer-based cleaning cycles; remote app control via wireless module
PowerAC mains or battery/solar hybrid for outdoor locations

Things to plan for (US market)

  • UL 48 - Standard for Commercial Electric Signs and Luminaires. Electrical components, including the motor and power supplies, must meet safety standards for outdoor use.
  • IP Rating - Ingress Protection rating (e.g., IP65) is critical for outdoor units to protect the hydraulic seals and electronics from rain and dust.
  • NEC (National Electrical Code) - Wiring methods and disconnect switches must comply with local codes for permanent installations.
  • OSHA Guidelines - If the lift mechanism exposes moving parts during maintenance, guarding or interlocks may be required for worker safety.

How a project runs

  1. Inquiry - Define size, location (indoor/outdoor), and power source.
  2. Design - Select hydraulic actuators, brush type, and enclosure specs.
  3. Prototype - Build a working unit to test lift smoothness, seal integrity, and cleaning efficacy.
  4. Certification - Send samples for UL testing if applicable for the target market.
  5. Production - Fabricate cabinets, assemble hydraulics, install electronics, and quality check.

Quantities & timeline

Hydraulic cylinders and custom-molded plastic housings for the brush system require lead times similar to industrial equipment. Metal fabrication for the cabinet is standard. Certification testing adds 4-8 weeks. Send us your dimensions, power requirements, environmental conditions, quantity and target price and we will reply with options.
