Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, and more particularly to a folding headrest and seat with music function. Background Technology

[0002] With the development of the automotive industry and the increasing demands of people for driving and riding experience, the functions of car seat headrests are becoming increasingly diversified. Traditional car headrests mainly serve the functions of supporting the occupant's head and protecting the neck during a collision. Their structure typically includes the headrest body and a headrest rod fixed to the seat back frame. The headrest rod is mostly in the form of a straight rod, with the headrest body fixed to the top of the headrest rod in a relatively fixed position.

[0003] To enhance passenger entertainment, some car models have begun integrating music playback functions into headrests. However, existing headrests with music functionality suffer from the following drawbacks: First, the integration design of the speaker and headrest structure is unreasonable, resulting in messy wiring harnesses that affect assembly efficiency and reliability. Second, the headrest shell structure is complex, with numerous parts, cumbersome assembly processes, and high manufacturing costs. Third, the connection between the headrest and the seat frame is not robust enough, making it prone to loosening and rattling under bumpy driving conditions. Furthermore, with the increasing intelligence of car seats, functions such as seat reclining and lying down are becoming standard features in high-end models. To achieve a large angle of reclining of the seat back, the headrest needs to fold backward synchronously with the backrest to avoid interference with the rear seats or other structures in the vehicle. However, existing headrests fail to effectively integrate music functionality with the headrest folding function; they are often designed as separate modules, resulting in a bulky overall structure. Additionally, traditional straight-bar headrests cannot rotate backward with the backrest frame when the seat back is folded down, limiting the realization of the seat reclining function.

[0004] Therefore, there is an urgent need for a headrest product that is simple in structure, easy to assemble, reliable in connection, and can simultaneously play music and fold back as a whole. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides an integrated rear-folding headrest and seat with music functionality, aiming to solve the defects of existing similar products, such as complex structure, cumbersome disassembly and assembly, high manufacturing cost, and unreliable headrest connection and fixation; at the same time, it solves the technical problem that traditional headrests cannot simultaneously achieve the overall rear-folding of the seat and audio playback, thus balancing driving comfort and driving safety.
