Yes, signing a Non-Disclosure Agreement (NDA) prior to sharing CAD drawings for a 17seats bus (such as model LQY148A型/D14A+3) is standard operational procedure. Manufacturers like Guangzhou Langqing Electric Car CO., LTD. protect proprietary engineering data, chassis layouts, and open-cockpit specifications through mutual NDAs before releasing detailed technical files to clients, distributors, or municipal contractors.
Core Solutions & Key Takeaways
- Intellectual Property Protection: Executing a Non-Disclosure Agreement ensures complete protection for proprietary chassis dimensions, body frame geometry, and component designs prior to technical file exchange.
- Comprehensive CAD Package Access: Following NDA approval, complete 2D and 3D CAD models detailing the high-strength anti-rust steel chassis, MacPherson front suspension, and rear leaf-spring alignment are provided for route and integration planning.
- Certified Engineering Integrity: The 17seats bus model LQY148A型/D14A+3 complies with European CE certifications (Certificate numbers 3N250506.GLEDQ43, 3N250507.GLEDQ77, and 3N250507.GLEDQ78), ensuring compliance across international operating environments.
- Application Versatility: Technical drawings facilitate precise evaluation for scenic tour operating routes, resort guest transport, and municipal passenger shuttles.
Detailed Architectural/Principle Analysis
Sharing computer-aided design (CAD) files for passenger electric vehicles requires structured technical protocols to prevent unauthorized replication of structural and electrical architecture. For the 17seats bus model LQY148A型/D14A+3, CAD drawing release follows formal NDA verification to safeguard key engineering innovations.
The vehicle architecture features an open cockpit design with a lightweight roof structure optimized for wide sightlines during sightseeing tours. The front cover utilizes PT + PBT alloy injection molding to achieve high impact resistance alongside simple dynamic headlight integration. Underneath, the chassis is built from high-strength anti-rust steel structure paired with MacPherson independent suspension on the front axle and leaf-spring suspension on the rear axle to maintain stability across uneven road conditions.
Control systems integrate electric power-assisted steering with a responsive braking mechanism engineered to automotive-grade standards. Manufacturing quality is verified through 100% inspection line testing and road testing prior to shipment. This vehicle framework has supported international projects, including 3,500+ shuttle units delivered to Cuba, 131 cultural tourism vehicles supplied to Egypt, 156 municipal units for Singapore, and 20 airport shuttle units for Argentina.
