[0025] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0026] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". Other explicit and implicit definitions may also be included below.

[0027] like Figure 1~Figure 3 As shown, the car seat foot massage system includes a foot massage component 200 , a plurality of pressure sensors (not shown in the figure) and a massage controller 500 .

[0028] The foot massage assembly 200 includes a foot massage pad 1 and an air pump 400 disposed under the car seat. The foot massage pad 1 is provided with an air circuit 2 and a massage air column area, and the massage air column area is divided into symmetrically arranged left and right foot areas 11 and 12. Each foot area is provided with a plurality of air columns 3 corresponding to the acupuncture points on the sole of the foot. The air pump 400 is connected to the air circuit 2, and the air circuit 2 is connected to the air column 3, so that the air pump 400 can inflate and deflate the air column 3. Passengers in the car can take off their shoes when riding and put their feet on the foot massage pad 1 for massage. The driver can also take off his shoes for massage when parking.

[0029] The design of the massage air column area (air column shape, air column size, air column lifting height, air column arrangement, air column number, etc.) is based on the structure of the human foot and acupoint information. The acupoints on the foot are dense and the foot structure is complex, so in a preferred solution, the air column 3 is cylindrical, with 47 air columns in each foot area, and a total of 94 air columns in the left foot area 11 and the right foot area 12. The diameter of the air column 3 is 15 mm, and the maximum lifting height of the air column 3 is 8 mm, which can fit the sole of the foot well and press the foot muscles. The arrangement of the air column 3 adopts a closely arranged form, which can ensure that all acupoints on the foot can be pressed, conforms to ergonomics, and can provide a comfortable massage for the sole of the human foot. The massage controller 500 and the air pump 400 are arranged at the bottom of the seat basin to achieve reliable installation.

[0030] The pressure sensors are arranged on the backrest and the cushion of the car seat 100. The positions and numbers of the pressure sensors are based on the theory of human body pressure distribution. The body pressure distribution refers to the pressure distribution of the body weight on the seat and the backrest when the body is in a sitting position. The recognition target of the pressure sensor is to recognize the changes in the sitting position of the human body by identifying the pressure distribution of the human body. In a preferred embodiment, the pressure sensor is a capacitive sensor. When the sitting position of the human body changes, the capacitance distribution of the capacitive sensor will change. The capacitive signal is given to the massage controller 500, and the sitting position of the human body can be recognized.

[0031] From the perspective of control strategy, the massage controller 500 can receive the detection signal from the pressure sensor to perform foot massage. For example, the massage controller 500 can continuously detect the sitting posture of the passenger. After a certain period of time (for example, set to 1 hour) of car driving, if the passenger increases the frequency of body movement (sitting posture change frequency), it means that the passenger has become tired, and the massage controller 500 will activate the foot massage function.

[0032] In a specific embodiment, the left foot area 11 and the right foot area 12 each include different massage areas, each massage area corresponds to a different foot acupuncture point reflex area, refer to Figure 3 , such as facial massage area, thyroid massage area, lung massage area, kidney massage area, intestinal massage area, genital massage area, etc., and each massage area is inflated and deflated in a preset order. The foot massage mode (the order of inflation and deflation of each air column 3) is designed according to the foot structure and acupoint location information, and can perform targeted pressing on each acupoint of the human foot to relieve the pressure of the passenger. For example: the massage mode is to press different acupoint reflex areas of the passenger's foot in sequence, and the order, pressure and time of the pressed acupoints refer to the order, strength and time of the pressing of the foot technician. In a preferred example, the order of inflation and deflation of the acupoint reflex area is: kidney massage area → lung massage area → thyroid massage area → kidney massage area → intestinal massage area → genital massage area → lung massage area → facial massage area → thyroid massage area → kidney massage area → intestinal massage area → genital massage area. In the above order, when the previous area is inflated and deflated, the next area starts to inflate, and so on.

[0033] On the basis of the above embodiments, in this embodiment, the massage controller 500 obtains the current driving state of the vehicle through the vehicle controller. When the vehicle is in a high-speed sharp turn state, the air column corresponding to the foot area outside the turning direction is inflated. It can be understood that when the car makes a sharp turn at high speed, the passenger will be affected by the centrifugal force, and the body will tilt outward, causing discomfort or even safety hazards. At this time, the air column corresponding to the foot area outside the turning direction is inflated to provide greater support for the foot, which can help the passenger offset the impact of the centrifugal force and increase comfort and ride stability. The vehicle controller can make a judgment based on the preset thresholds such as speed and acceleration for determining the high-speed sharp turn of the car, and those skilled in the art can set it according to the actual situation such as vehicle performance. When turning, the outer foot can be given greater support, or the inner foot area can be deflated, the outer foot area can be inflated, or the air column pressure of the outer foot area can be greater than the air column pressure of the inner foot area in the turning direction.

[0034] On the basis of the above embodiments, in this embodiment, the car seat foot massage system also includes a massage switch key 300, which is installed on the armrest of the car seat 100. The massage switch key 300 is electrically connected to the massage controller 500. When the passenger presses the massage switch key 300, the massage controller 500 detects the massage signal and controls each massage area to perform massage.

[0035] In summary, in this embodiment, the control strategy includes:

[0036] 1. Fatigue massage mode: The system sensor can continuously detect the passenger's sitting posture; after a certain period of car driving (set to 1 hour), if the passenger increases the frequency of body movement, the control will activate the foot massage function.

[0037] 2. Active massage mode: When the passenger presses the massage switch, the controller detects the massage signal and controls each airbag to perform massage.

[0038] 3. Foot support when the car is driving at high speed: When the car makes a sharp turn, the massage airbags located on the outside will inflate to provide greater support for the feet.

[0039] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
