[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0044] In the description of the present invention, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to". The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, in the description of the present invention, "multiple rows" means at least two rows, such as two rows, three rows, etc., unless otherwise clearly and specifically defined.

[0045] The most important acupuncture points in the calf are Chengshan and Chengjin. When the human body stands, the inner side of the calf will feel slightly tight. Chengshan and Chengjin are a kink of tendons, bones and flesh, and are the most direct stress points. The weight of the person will fall on this point, which is very important. Chengshan is located on the calf. The muscles on the inner side of the calf are very developed. When we stand on tiptoe, the muscles here will bulge slightly. The depression at the end of the bulge is Chengshan. It is between Weizhong and Kunlun, that is, in the middle of the two human-shaped muscles, generally 8 inches below the knee, and Chengjin is generally 3 inches above Chengshan. The best way to effectively massage the calf acupuncture points is: first, rub the inner side of the calf up and down with your hands, generally 5 cm above the Achilles tendon to 5 cm below the knee, and rub up and down for about 10 times; then use both hands to press the inner side of the calf Chengshan from the middle of the calf for about 10 times. In order to simulate this massage mode, the present invention provides a method for massaging the calf leg support of a car seat, wherein the calf leg support massages the calf through a massage air bag 101, wherein the massage air bag 101 includes multiple rows, and the method is executed by a controller, such as Figure 1 As shown, the following steps are included:

[0046] Step 1: The controller receives a massage start instruction;

[0047] Step 2: In response to the received massage start instruction, the controller controls the air pump to start;

[0048] Step 3: The controller controls the air inlet valves of the corresponding row of massage air bags 101 to open and the air outlet valves to close according to the preset first sequence, and controls the air inlet valves of other rows of massage air bags 101 to close, so that the massage air bags 101 in that row are inflated. Sequentially, the controller controls the inflation and exhaust of each row of massage air bags 101 according to the first sequence, completing a first mode to massage the calf up and down; the controller controls the massage air bags 101 to complete the first mode N1 times;

[0049] Step 4: The controller controls the air inlet valves of each row of massage air bags 101 to open at the same time and the exhaust valves to close at the same time, so that each row of massage air bags 101 is inflated at the same time; then controls the air inlet valves of each row of massage air bags 101 to close at the same time and the exhaust valves to open at the same time, so that each row of massage air bags 101 is exhausted at the same time, completing a second mode; the controller controls the massage air bags 101 to complete the second mode N2 times;

[0050] Step 5: Repeat steps 3 and 4 until the controller receives a massage stop instruction.

[0051] Step 3 and step 4 constitute a large cycle. Preferably, the number of first mode cycles N1 and the number of second mode cycles N2 of a large cycle include 10-20 times. The massage airbag 101 has a certain coverage area. In step 3, the massage airbag 101 is inflated and deflated 10 times in an up-and-down cycle, which can simulate the massage technique of "pressing and kneading from 5 cm above the Achilles tendon to 5 cm below the knee for about 10 times", and massages the calf in an up-and-down cycle. In step 4, each massage airbag 101 is inflated and deflated 10 times in a cycle at the same time, and the calf is massaged in an overall cycle, which can simulate the massage technique of "pressing the inner side of the calf Chengshan acupoint from the middle of the calf with both hands for about 10 times". The massage airbag repeats the large cycle to massage the calf until the controller receives a stop massage instruction. In this way, after the massage airbag 101 massages in an up-and-down cycle, it massages in an overall cycle, so that the massage airbag 101 can simulate the best massage technique, massage the calf more effectively, and relax the leg.

[0052] A control button can be set on the car seat, and the control button is electrically connected to the controller. The passenger can issue a massage start command and a massage stop command through the control button. When the controller receives the massage stop command, step 6 is executed to control the air pump to turn off and control each massage air bag 101 to exhaust air, so that the massage air bag 101 returns to its original state.

[0053] In some embodiments, the first sequence is a top-down cycle, or a bottom-up cycle, so that the massage airbag 101 massages the calf up and down. For example, when the massage airbag 101 includes two rows, each row of massage airbags 101 is sequentially arranged as the first row and the second row from top to bottom, and the first sequence is set as the first row→the second row, and the air is inflated and deflated once from top to bottom as a first mode; or, the first sequence is set as the second row→the first row, and the air is inflated and deflated once from bottom to top as a first mode. When the massage airbags 101 include three rows, the upper, middle and lower rows, each row of massage airbags 101 is sequentially arranged as the first row, the second row and the third row from top to bottom, and the first sequence is set as the first row → the second row → the third row, and the air is inflated and deflated once from top to bottom as a first mode; or, the first sequence is set as the third row → the second row → the first row, and the air is inflated and deflated once from bottom to top as a first mode; or, the first sequence is set as the first row → the second row → the third row → the second row → the first row, and the air is inflated and deflated once from top to bottom and then upward as a first mode; or, the first sequence is set as the third row → the second row → the first row → the second row → the third row, and the air is inflated and deflated once from bottom to top and then downward as a first mode. One first mode constitutes a small up-and-down cycle, and a large cycle performs N1 small up-and-down cycles.

[0054] In order to more conveniently control the opening and closing of the intake valve and the exhaust valve, the opening and closing of the intake valve and the exhaust valve are performed in the opposite mode, the intake valve is opened, the exhaust valve is closed, the intake valve is closed, and the exhaust valve is opened. For example, the massage airbags 101 are in two rows. When the first row of massage airbags 101 are inflated, the intake valve of the first row of massage airbags 101 is opened, the exhaust valve is closed, and the intake valve of the second row of massage airbags 101 is closed, and the exhaust valve is opened. At this time, if the second row of massage airbags 101 are in the original state, the second row of massage airbags 101 can be prevented from being inflated. If the second row of massage airbags 101 have been fully inflated, the second row of massage airbags 101 can be exhausted. When the first row of massage air bags 101 is inflated, the air inlet valve of the first row of massage air bags 101 is controlled to close and the exhaust valve is opened, and the air inlet valve of the second row of massage air bags 101 is opened and the exhaust valve is closed, so that the first row of massage air bags 101 can be exhausted and the second row of massage air bags 101 can be inflated, completing a first mode; in sequence, the first row of massage air bags 101 and the second row of massage air bags 101 are alternately inflated and deflated, thereby massaging the calves up and down.

[0055] In order to achieve a better comfort level, when the air pump inflates the massage airbag 101, the massage airbag 101 is lifted up by 8-12 mm per second, the inflation time is 2-5 seconds, and the maximum lifting amount of the massage airbag 101 is 20-36 mm. When the inflation is completed, the massage airbag 101 reaches the maximum lifting amount. By setting a suitable lifting height and speed of the massage airbag 101, the massage intensity and massage frequency can be controlled to achieve a better comfort level. For example, the massage airbag 101 can be lifted up by 20 mm, 24 mm, 25 mm, 28 mm, 30 mm, 32 mm, 35 mm, 36 mm, etc. within 2 seconds, 3 seconds, 4 seconds or 5 seconds at a speed of 8 mm / s, 9 mm / s, 10 mm / s, 11 mm / s or 12 mm / s to achieve a comfortable massage effect.

[0056] In the sitting position, the calf of the passenger is not in point-to-point contact with the leg rest, but in surface-to-surface contact. Each row of massage air bags 101 may include multiple ones to increase the contact area with the calf. Preferably, each row of massage air bags 101 includes three, and the maximum lifting amount of the middle massage air bag 101 is greater than the maximum lifting amount of the massage air bags 101 on both sides. When the calf is placed on the leg rest, the inner side of the calf contacts the middle massage air bag 101. Increasing the maximum lifting amount of the middle massage air bag 101 can increase the massage intensity of the inner side of the calf and make the massage effect better. For example, the size of the air inlet valve of the middle massage air bag 101 can be increased, the inflation speed can be increased, and the maximum lifting amount of the middle massage air bag 101 can be increased; the size of the middle massage air bag 101 can also be reduced, and at the same inflation speed, the lifting amount of the middle massage air bag 101 is made greater than the lifting amount of the massage air bags 101 on both sides. Preferably, the maximum lifting amount of the middle massage airbag 101 is 1.1-1.5 times the maximum lifting amount of the massage airbags 101 on both sides. For example, the maximum lifting amount of the middle massage airbag 101 can be set to 1.1 times, 1.2 times, 1.3 times, 1.4 times or 1.5 times the maximum lifting amount of the massage airbags 101 on both sides.

[0057] The air inlet valves of each massage air bag 101 are connected to the main pipe through each branch pipe, and the main pipe is connected to the air pump. The main pipe is provided with a regulating valve, and the regulating valve is electrically connected to the controller. When the massage air bag 101 is inflated according to the first mode, the controller controls the inflation of the single-row massage air bag 101. When the massage air bag 101 is inflated according to the second mode, the controller controls the inflation of all the massage air bags 101. In both modes, each massage air bag 101 needs to maintain an inflation speed with better comfort. The inflation speeds of the massage air bags 101 in the two modes are basically the same. The total inflation volume of the massage air bags 101 in the two modes can be controlled by controlling the opening area of ​​the regulating valve, so that the inflation volume and inflation speed of a single massage air bag 101 in the two modes are kept consistent. Therefore, step 3 also includes: the controller controls the opening area of ​​the regulating valve to be A1; step 4 also includes the controller controlling the opening area of ​​the regulating valve to be A2.

[0058] The opening area A of the regulating valve can be calculated according to Formula 1:

[0059] Formula 1:

[0060] ;

[0061] Where A is the opening area of ​​the regulating valve, mm 2 ;

[0062] V—total inflation volume, L;

[0063] t—inflation time, s;

[0064] P1—air pump pressure, Pa;

[0065] P2—initial pressure in the massage air bag, Pa;

[0066] P′—pressure of the massage air bag after sonic inflation, Pa;

[0067] K—adiabatic index;

[0068] R—gas constant, J / (K∙mol);

[0069] M—gas molar mass, kg / mol;

[0070] T—gas temperature, K;

[0071] P″—Pressure of the massage air bag at the beginning of subsonic inflation, Pa.

[0072] According to the preset inflation time t and the total inflation volume V of the massage airbags 101 in the two modes, the corresponding opening area A of the regulating valve can be obtained by formula 1. In step 3, the controller controls the inflation of the single-row massage airbags 101, and the opening area of ​​the regulating valve is A1; in step 4, the controller controls the inflation of all massage airbags 101, and the opening area of ​​the regulating valve is A2. The ratio of the opening area A2 of the regulating valve in step 4 to the opening area A1 of the regulating valve in step 3 is equal to the ratio of the total inflation volume V2 of all massage airbags 101 to the total inflation volume V1 of the single-row massage airbags 101. For example, when there are two rows of massage airbags 101, the total inflation volume V2 in step 4 is twice the total inflation volume V1 in step 3, and the opening area A2 of the regulating valve in step 4 is twice the opening area A1 of the regulating valve in step 3.

[0073] At normal temperature and pressure, the adiabatic index K is set to 1.4, the gas constant R is set to 8.3143 J / (K∙mol), the gas molar mass M is set to 0.029 kg / mol, and the gas temperature T is set to 293 K. Due to the noise problem of the air pump in the car, a high-power air pump cannot be used, and the air pump pressure P1 can be set to 45 kPa; the initial pressure P2 in the massage air bag 101 can be set to 0.5 Pa, which is basically in a vacuum state. When the ratio of the gas source pressure to the pressure in the vacuum container is greater than the critical pressure ratio, the inflation process is a sonic inflation process, otherwise it is a subsonic inflation process. The critical pressure ratio of air is about 1.9. When air is drawn by the air pump to inflate the massage air bag 101, the gas source pressure ratio is much greater than the critical pressure ratio. Therefore, the inflation process is first sonic inflation and then subsonic inflation. The pressure P′ of the massage air bag 101 after sonic inflation is P1 / 1.9Pa; the pressure P″ of the massage air bag 101 at the beginning of subsonic inflation is P1 / 1.9Pa.

[0074] Substituting the above values ​​into Formula 1, we can obtain Formula 2 for calculating the opening area A of the regulating valve at normal temperature and pressure. Specifically, Formula 2 is:

[0075] ;

[0076] Where A is the opening area of ​​the regulating valve, mm 2 ;

[0077] V—total inflation volume, L;

[0078] t—inflation time, s.

[0079] According to the total inflation volume V and inflation time t of the preset corresponding mode, the opening area A of the regulating valve in this mode can be calculated.

[0080] In order to effectively massage Chengshan acupoint and Chengjin acupoint, the position of the massage air bag 101 needs to be more accurately aligned with Chengshan acupoint and Chengjin acupoint. Preferably, Figure 2 As shown, the massage airbags 101 include two rows, which correspond to the approximate positions of Chengshan acupoint and Chengjin acupoint respectively. The upper boundary of the leg support roughly corresponds to the position of the Heyang acupoint of the calf. Therefore, the first row of massage airbags 101 is arranged at a distance of 8-12 cm from the center of the upper boundary of the leg support (the distance between the Heyang acupoint and the Chengjin acupoint is about 3 inches), and the second row of massage airbags 101 is arranged below the first row of massage airbags 101, and the center is 8-12 cm away from the center of the first row of massage airbags (the distance between the Chengshan acupoint and the Chengjin acupoint is about 3 inches). In this way, the two rows of massage airbags 101 can massage two acupoints relatively accurately. The width L of each massage airbag 101 is set to 8-10 cm. The upper and lower widths of the massage airbags 101 are relatively large. When the calf moves slightly on the leg support, the two rows of massage airbags 101 can still align with the two acupoints.

[0081] In some embodiments, the massage method further comprises adjusting the position of the massage airbag 101 along the length direction of the calf by means of an adjustment mechanism. By pushing the massage mechanism 100 provided with the massage airbag 101 to move, the position of the massage airbag 101 can be adjusted along the length direction of the calf, so that the massage airbag 101 can adapt to the calf position of passengers of different heights, so that passengers of most heights can effectively relax their legs, expand the adaptability range of the calf leg support massage mechanism 100, and improve driving and riding comfort.

[0082] The massage airbag 101 can massage the calf up and down in a circular massage according to the first mode, and can massage the calf as a whole in a circular massage according to the second mode, and the massage airbag 101 can accurately align the Chengshan acupoint and the Chengjin acupoint, thereby simulating the best massage technique for massaging the calf acupoints, and can more effectively massage the acupoints and relax the legs. Pressing and kneading the Chengshan acupoint and the Chengjin acupoint can help to discharge moisture, promote blood circulation, relieve calf fatigue, remove moisture, treat leg cramps, relieve back pain, and can also treat diseases such as constipation and prolapse. At the same time, the Chengshan acupoint and the Chengjin acupoint are on the foot-sun bladder meridian, and the bladder meridian is the master of the body's yang energy. On the one hand, the Chengshan acupoint and the Chengjin acupoint are the gathering places of the tendons, bones, and flesh that bear the most pressure on the whole body, and on the other hand, they are the hubs of the meridians with the most yang energy in the human body, so they can expel moisture from the human body by invigorating the yang energy of the solar bladder meridian. Most people will feel obvious soreness and pain when massaging the Chengshan and Chengjin acupoints. This is because the leg muscles cannot relax. However, after massaging the Chengshan and Chengjin acupoints for a period of time, the Yang energy on the bladder meridian can be gathered, which has the effect of relaxing and removing dampness.

[0083] The calf leg support massage method can be used for car seats, and can also be used for ergonomic chairs, massage chairs, gaming chairs and other seats with massage functions for office, leisure, medical and other purposes.

[0084] The above description is only the best embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
