What the claims cover, in plain language
Claim 1 defines a height-adjustable power toolbox comprising a box body (1) with universal wheels (2) having brakes. The lower end has hydraulic cylinders (3) connected to cushion blocks (4). The bottom inner cavity holds a battery component (5) and an electromagnetic valve (6). A control box (7) on the side contains a controller linked to the battery, valve, and sockets (11). Inside, a storage drawer (8) features a tool storage area (9) with an instrument groove (91), a first trough (92) split by a partition (10), and a second trough (93). The lid (12) has hooks (13), a bag (14), and an LED lamp (15).
Claim 2 adds a push-pull bar (16) on the base plate. Claim 3 specifies four sets of wheels, cylinders, and blocks arranged at the four corners. Claim 4 details the control box having buttons and a display screen. Claim 5 mentions sealed lockers on the drawer and lid.
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 lapsed due to non-payment of fees. It has no US or other foreign counterpart.
Two points to settle early:
- Other patents may exist. Mobile tool storage with integrated electronics is a competitive field. While this specific hydraulic corner-lift design is not patented in the US, similar ergonomic lifting mechanisms or smart-toolbox features may be covered by active US patents held by major tool brands. A freedom-to-operate (FTO) review is recommended before mass production.
- Electrical Safety. Integrating batteries and outlets into a metal chassis requires strict adherence to electrical safety standards to prevent shock or fire risks.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Lifting Mechanism | Hydraulic cylinders vs. scissor lifts or manual jacks. |
| Capacity | Number of drawers, volume of storage troughs. |
| Electronics | Battery capacity (Li-ion vs. Lead-acid), socket types (USB, AC). |
| Materials | Steel gauge, plastic injection molding for partitions. |
| Wheels | Castor size, brake type, tread material. |
| Finish | Powder coating colors, logo placement. |
Things to plan for (US market)
- UL 62368-1 or UL 1593: Standards for audio/video/information technology equipment or lamps, relevant for the LED and control electronics.
- FCC Part 15: If the control box uses wireless communication or emits radio frequency energy, certification is required.
- OSHA Guidelines: General workplace safety regarding pinch points and stability of mobile equipment.
- California Prop 65: Screening for lead, cadmium, or other chemicals in plastics and finishes.
How a project runs
- Inquiry - Define height range, load capacity, and electrical specs.
- Design - CAD modeling of hydraulic mounts, drawer layouts, and PCB integration.
- Prototype - Build functional samples for lift testing and electrical safety checks.
- Pilot Run - Small batch production to validate assembly lines and QC processes.
- Production - Mass manufacturing of stampings, moldings, and final assembly.
Quantities & timeline
Hydraulic components require sourcing from specialized suppliers or custom machining. Injection molds for the intricate partition boards and control box housings take 4-6 weeks to produce. Electronics require supply chain validation for battery cells. Send us your target height range, electrical specifications, quantity, and budget and we will reply with options.
