Massage chair large and small more than 1500 parts are assembled and become, its technological complexity far more than general home appliances.
1, The movement
The core components of the massage chair movement, similar to the heart of the human body, is the mechanical center of the massage chair. Movement with manipulator and control manipulator motor device, through the IC control manipulator speed, position, manipulation and range, to simulate the effect of hand, the quality of the movement directly determines the massage chair massage effect. The main board + motor + manipulator constitutes the most critical part of the massage chair, which is also a core component of the price of the massage chair varies greatly.
2. Manipulator
Through the design of the program, the manipulator can realize a variety of simulated human massage techniques, through the massage principle, to achieve the massage effect, the manipulator massage is the most important way of massage chair massage. The manipulator is composed of a connecting rod and a massage ball, which is the terminal of the massage program. Massage the body from top to bottom according to instructions. Now the household massage chair is basically a massage technique to prevent hands, but the specific structure of each company is different, which is a magic weapon to stand firm in the industry.
3, Electrical
Motor (commonly known as "motor") is based on the law of electromagnetic induction to achieve electrical energy conversion or transmission of an electromagnetic device. Its main role is to produce driving torque, as a massage chair all kinds of manipulation and movement to provide power support, massage chair each program action is to rely on him to provide continuous power energy, massage chair motor is generally based on three-phase asynchronous motor.
Kneading function: Imitate hand massage, drive turbine transmission mechanism with motor, drive kneading shaft to complete kneading function.
Percussion function: THE model imitates hand percussion, and the eccentric shaft is driven by the motor to achieve the percussion function with the kneading shaft.
Back massage: Back massage department through the sensor with the circuit, to achieve the back width of the massage width adjustment.
Massage intensity adjustment: through the sensor and circuit system, the speed of kneading and the intensity of knocking can be adjusted.
4, Guide
Guide rail is used for manipulator operation support, similar to the skeleton of the human body, is the operation path of the massage chair. The movement moves freely up and down the guide rail, and the length of the guide rail also directly determines the scope of massage. There are two kinds of massage chair guides in the market, one is L guide, the other is SL guide, which is designed according to the concept of the curve of the human spine, and is very in line with the ergonomic design. The length, Angle, fit and stability of the guide determines the experience of massage. The design of the guide is also one of the core parameters of the massage chair.
5, The mainboard
The motherboard of the massage chair is similar to the motherboard of the computer. It is the carrier of the program, motor operation and power supply of the massage chair, similar to the brain of the human body, issuing instructions. Massage chair through the control system massage program command, motherboard received after the massage chair massage system issued instructions, the manipulator work along the guide rail according to the instructions. Inside the motherboard is the chip, the processor, which is the brain of the massage chair, responsible for processing all kinds of commands.
6. Air bag system
In addition to the massage of the massage chair movement moving up and down along the guide rail, there is also a massage method is the air bag massage, the air bag according to the air pump in each part of the air, the use of air pressure to the depth of the parts of the package, to achieve a certain pressure balance, continue to squeeze the parts to achieve the effect of massage. The material of the air bag is mainly TPU environmental protection cloth, which is the same material as the car's air bag, and the process of inflating and deflating is completed together with the air pump, air valve and inflation pipe. Air bags mainly target the shoulder, waist, sitting, arm, calf and leg parts.
7. Foot machine system
The foot machine system is composed of parts that massage the legs and feet. The foot machine system is a separate massage system that is different from the host massage. The massage methods also include two sets of mechanical massage and air bag massage system, which is also an important experience point of differentiated massage. Massage chair foot machine is not the same for each brand, the direction of research and development is not the same, some brands pay attention to the number of air bags, some brands pay attention to air bag kneading, some brands pay attention to the development of foot massage ball.
