Driven by the RK3506 industrial-grade HMI platform, the armrest / side-panel control integrates offline voice, touch UI and a core-mechanism CAN/RS485 bus — taking the massage chair from "control board" to "smart, networked + health-upgraded". Highly integrated, lower cost, multi-function: one platform fits multiple product tiers.
The same RK3506 platform scales from entry-level models to high-end networked models as needed.
RK3506 + LVGL touch UI makes program, intensity, zone and duration clear at a glance — intuitive operation.
Offline voice to pick a program / adjust intensity / switch modes — even seniors can "speak" comfort.
CAN / RS485 connects the massage robotic arm, air pump and motors for precise complex-technique execution.
WiFi music / video / voice assistant lifts the single-unit experience and premium.
Reserved physiological-sensor interface (PPG / BIA, optional) evolves toward health monitoring.
High integration lowers BOM complexity, enabling "small form + multi-function" model iteration.
Hardware composition of a typical massage-chair HMI and main-control unit.
| Subsystem | Key spec / tech | Role |
|---|---|---|
| Main controller | RK3506 (3×Cortex-A7 + M0, industrial −40~85℃) | HMI rendering, mechanism scheduling, networking |
| Display | MIPI DSI / RGB, up to 1280×1280, LVGL | Armrest/side touch UI |
| Voice | External audio codec + mic; offline voice wake / broadcast (optional Bestom M08D audio module) | Local voice-controlled massage |
| Touch | Capacitive / resistive, multi-point | Panel operation |
| Core-mechanism interface | CAN / RS485 / UART / SPI | Connects robotic arm, air pump, motors |
| Network | WiFi + BLE (optional Zigbee) | Networked entertainment, mobile interconnect, OTA |
| Sensor reserved | I2C / SPI interface, mountable PPG / BIA (optional) | Health-function upgrade reserved |
| Power | ~2.4 W with screen | Long-term low-power online |
| Massage-chair design highlights | |
|---|---|
| Operating temperature | Industrial −40 ~ +85 ℃ |
| Real-time core | M0 co-processor handles mechanism real-time I/O |
| Graphics framework | LVGL, light and high-frame-rate, smooth animation |
| Bus compatible | CANopen / Modbus / private mechanism protocols adaptable |
| Integration | Single chip covers HMI + networking + voice |
| Upgrade path | Hardware reserved, software OTA evolution |
| Cost | High integration lowers peripheral & BOM complexity |
| Long-term supply | Rockchip industrial line, long lifecycle |
Layering offline voice on top of the control panel makes the massage chair "understand". Voice and touch dual modes cover users of different ages and habits.
Local keyword wake and command recognition, no network needed — fast and stable.
Intents like "full-body relax / focus shoulders-neck / gentle mode" map directly to massage programs.
Voice for quick start, touch for fine tuning — complementary experience.
Store different family members' preferred programs, call them with one voice command.
Voice recognized locally; sensitive audio never goes to cloud, home compliant.
Voice commands go via CAN/RS485 to the mechanism for closed-loop execution of technique and intensity.
Massage-chair electronics follow a progressive path — mass-production control board → smart networked entertainment → health-function upgrade — and the RK3506 platform reserves capacity for all three steps at once.
| Stage | Goal | RK3506 platform support |
|---|---|---|
| Step 1 · Mass-production control board | Stable, lower cost, multi-model compatible | High-integration single chip, LVGL + mechanism bus |
| Step 2 · Smart networked | WiFi entertainment, voice assistant, OTA | Networking + voice codec + display integrated |
| Step 3 · Health-upgraded | Physiological sensing, health-monitoring interaction | Sensor interface reserved, connects PPG/BIA (optional) |
The hard part of massage-chair electronics is "mass-production stability, mechanism-protocol adaptation, cost-down and fast iteration". BesTom has long experience in control-board mass production and electromechanical integration.
Accumulated delivery from PCB module to finished-unit electronics, supporting high-volume ramp-up.
HMI, mechanism bus and structure co-design shorten finished-unit introduction.
High-integration platform lowers peripheral complexity, fitting "small form + multi-function" models.
Self-developed audio module (M08D) and HMI platform work end-to-end.
Networked entertainment and health sensing reserved, protecting hardware investment and enabling smooth iteration.
Shenzhen R&D + contracted manufacturing, with integrated DFM, thermal simulation and EMC remediation.
Connect the chair to a "store-edge brain" — networked → entertainment-enabled → health-upgraded handled by one RK3588+1828 host.
