Description

Technical Field

[0001] This utility model relates to the field of seat technology, and in particular to a lightweight headrest frame for automotive seats based on a honeycomb aluminum core. Background Technology

[0002] Against the backdrop of the global automotive industry's transformation towards low-carbon, electrified, and intelligent manufacturing, lightweighting has become one of the core paths to improve overall vehicle performance and achieve energy conservation and emission reduction goals. According to data from the International Automotive Lightweighting Alliance, reducing vehicle curb weight can also reduce fuel consumption and increase the driving range of electric vehicles. As an important component of the vehicle body, the lightweight design of the seat system contributes significantly to the overall weight reduction. The headrest frame, as a key sub-component for seat safety and comfort, naturally becomes a key target for lightweighting optimization. As consumers' demands for automotive ride comfort and safety continue to rise, the headrest frame, in addition to meeting lightweight requirements, must also consider excellent mechanical properties, vibration damping characteristics, and spatial adaptability. Traditional frame structures are gradually becoming inadequate in the face of these complex demands. Steel frames are prone to abnormal noises due to vibration, and the anti-corrosion treatment process is complex, increasing the environmental pressure in the production process. Solid aluminum alloy frames, due to insufficient structural design flexibility, are difficult to adapt to the curved shapes of headrests and the installation requirements of internal functional components in different vehicle models, limiting the integration of intelligent seat functions.

[0003] Currently, car seats on the market mainly consist of seat backs and headrests. In situations where different drivers and passengers frequently switch positions or temporarily change their sitting posture, current car seat headrests lack a quick adjustment mechanism. When traveling in a family, members of different heights take turns sitting in the same seat, and each time they need to spend time readjusting the headrest height and angle, which affects the travel experience. During driving, if the sitting posture needs to be adjusted temporarily due to changes in road conditions, and the headrest needs to be adjusted, the existing adjustment method cannot respond quickly, which may cause the driver and passengers to be unable to concentrate on driving during the adjustment process.
