The human-machine code in the cockpit: the ergonomics of Sinotruk dump trucks is revealed
In the dusty construction site environment, the cab of the howo dump truck is a carefully designed "human-machine harmonious space". Today, let's go deep into the "nerve center" of this steel behemoth and analyze the ergonomic secrets that allow drivers to work continuously for 8 hours without fatigue.
01 Cockpit layout: "Control center" with everything at your fingertips
The howo dump truck cab adopts a semi-surround instrument panel design, which scientifically divides various control elements:
· Main control area: The steering wheel, shift lever, and handbrake are distributed in a fan shape to ensure that they can be easily reached when the driver's arms are naturally extended.
· Auxiliary function area: Secondary control keys such as air conditioning and lighting are located on the upper part of the center console, and differentiated button design is used to achieve blind operation.
· Emergency operation area: The emergency switches are concentrated at the driver's right knee position, which conforms to the natural reaction action in an emergency.
02 Seat system: a "mobile sofa" comparable to a luxury car
Howo dump truck is equipped with a fully suspended airbag seat, which hides many black technologies:
1. 6-way electric adjustment: adjustable seat height, front and rear position, backrest angle
2. Three-level shock absorption system: combined with mechanical springs, air bags and hydraulic damping, filtering more than 80% of bumps and vibrations
3. Active ventilation function: the seat has a built-in micro fan, and the ventilation mode can be turned on in summer
4. Lumbar support design: the support curve is specially optimized according to the driver's body shape characteristics
03 Optimized vision: 360-degree "glass house" with no blind spots
Howo designers achieve the best vision through a number of innovations:
· The front windshield adopts a "panoramic" design, with an area of 1.8㎡ and a tilt angle precisely controlled at 18°
· The rearview mirror system consists of a main mirror (200×150mm), a wide-angle mirror (150×100mm) and a blind spot mirror
· The A-pillar blind spot is controlled within 12° through a special cross-sectional shape, which is better than the industry average of 15°
· The cab floor adopts a sunken design, which reduces the driver's sitting height by 50mm and improves the front field of vision
04 Control interface: a model of intuitive design
1. Multi-function steering wheel: The commonly used control keys are integrated on the steering wheel spokes, and the thumb can easily operate
2. Combined instrument panel: adopts a "three-zone display" layout, and the key parameters are within the optimal field of view of 15°
3. Gear lever design: sinotruck dump The shift stroke of the truck is optimized to 90mm, and the operating force is controlled between 25-40N
4. Pedal system: clutch pedal force 85N, brake pedal force 60N, which is in line with the optimal force range of the human body
05 Environmental control system: "mobile office" on the construction site
Dual-zone automatic air conditioning: Sinotruck dump truck can adjust the cab temperature to the set value within 3 minutes
NVH optimization: through the application of 32 sound insulation materials, the idling noise is controlled below 72 decibels
Air filtration system: equipped with PM2.5 filtration function to ensure that the air quality in the cab is 20 times better than that outside
Storage space: various storage compartments with a total volume of 38L are designed, including special cup holders, document bags, etc.
The ergonomic design of dump trucks proves that even the most hardcore construction machinery can have the most humanized operating experience. From the millimeter-level layout of control components to the precisely calculated field of view, every detail reflects the "driver-oriented" design concept, and the core goal of "making human-machine interaction more natural and comfortable" will never change.
