[0002] During the driving of electric vehicles, drivers need to sit for long periods of time, which can easily lead to poor blood circulation and feelings of soreness and fatigue. In order to improve the driving comfort of drivers, massage cushions for electric vehicles are needed.

[0003] For example, a reciprocating vibration massage cushion for electric vehicles, patent number CN110901487B, has the following shortcomings in actual use:

[0004] The seat cushion provides reciprocating vibration massage to the driver's back, improving the device's practicality. It also allows for easy adjustment of the lumbar support pad height, making the massage seat cushion suitable for drivers of different body types and improving the device's comfort. However, it cannot simulate acupressure massage techniques and is difficult to meet professional needs such as meridian conditioning. Its fit and comfort are insufficient, with a hard contact surface that is difficult to adapt to the body's curves. Utility Model Content

[0005] In order to improve the technical problem that car massage cushions cannot simulate acupressure massage techniques, this application provides a car seat massage device.

[0006] The technical solution for a car seat massage device provided in this application is as follows:

[0007] A car seat massage device includes a backrest felt board fixed to a backrest suspension spring and a seat cushion felt board fixed to a seat cushion suspension spring. An air supply mechanism is provided on the back of the backrest felt board and below the seat cushion felt board. Two first felt boards and four second felt boards are provided at the front of the backrest felt board, and the first and second felt boards are respectively fixed to the front of the backrest foam.

An air pump tube D is connected to the air outlet of the silencer bottle, and the other end of air pump tube D is connected to a four-way quick connector. The other three ports of the four-way quick connector are respectively connected to the first multi-point massage control valve, the second multi-point massage control valve, and the third multi-point massage control valve through the first control valve air pump tube, the second control valve air pump tube, and the third control valve air pump tube.

[0016] By adopting the above technical solution, the four air pumps are connected in pairs and ultimately connected to the silencer bottle. The three multi-point massage control valves all receive air from the silencer bottle, which enables the silencer bottle to reduce noise throughout the air circuit and further improve the noise reduction effect.

[0017] Preferably, the first protruding air bag is connected to a first massage air tube, the other end of which is connected to two ports of the first multi-point massage control valve via a three-way pipe; the second protruding air bag is connected to a second massage air tube, the other end of which is connected to two ports of the second multi-point massage control valve via a three-way pipe; the third protruding air bag is connected to a third massage air tube, the other end of which is connected to two ports of the second multi-point massage control valve via a three-way pipe; and the massage air bag is connected to a fourth massage air tube, the other end of which is connected to two ports of the third multi-point massage control valve via a three-way pipe.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a car seat massage device.

[0035] Example 1

[0036] Reference Figure 1 A car seat massage device includes a backrest felt plate 1 fixed to a backrest suspension spring and a seat cushion felt plate 2 fixed to a seat cushion suspension spring.

[0037] Multiple felt boards are arranged in front of the backrest felt board 1, specifically two first felt boards 3 and four second felt boards 6, all of which are fixed to the front of the foamed backrest. Each first felt board 3 has three circumferentially distributed first convex air bags 4 attached to it; while each of the four second felt boards 6 has two second convex air bags 7 and two third convex air bags 8 fixed to it.

[0038] Two third felt boards 11 are provided above the seat cushion felt board 2, and each third felt board 11 is provided with three circumferentially distributed massage air bags 12.

[0039] The first raised air bag 4, the second raised air bag 7, the third raised air bag 8, and the massage air bag 12 are all connected to the air supply mechanism to realize functions such as inflation and deflation, thereby achieving a massage effect.

[0040] With the above settings, various massage methods can be achieved:

[0041] Pulse massage: Multiple air bags are inflated and deflated at a frequency of 5Hz-12Hz to achieve regular, intermittent force on the muscles, meridians and other parts of the body, simulating the patting action of a human hand to apply massage to the local area;

[0042] Tapping massage: Multiple air bags are inflated and deflated at a frequency of 0.5-3Hz to achieve continuous, rhythmic, and repetitive action on the muscles, meridians, and other parts of the human body, mimicking the high-frequency tapping movements of a professional massage therapist to massage specific areas.

[0043] Kneading massage: The three first convex point air bags 4 or massage air bags 12 are driven to circulate and deflate at a frequency of 0.5-3Hz to form clockwise / counterclockwise rotating massage movements. The kneading and pinching movements act on the muscles, meridians and other parts of the human body; simulating the kneading movements of human fingers, it performs deep, circular massage on muscle tissue, allowing muscle fibers to be fully stretched and relaxed.

[0044] It should be noted that in this embodiment, the first convex air bag 4, the second convex air bag 7, and the third convex air bag 8 are all Chinese patents (publication number CN218430968U) concerning a car seat air bag with a massage head, a car seat device, and a car seat air bag in a car, in order to achieve a more precise massage effect. Moreover, since the massage head is located at the very front, the intensity is higher and the massage effect is better; the massage head can simulate finger massage, resulting in a better effect; when the massage head is not inflated or not massaging, it will retract and will not protrude beyond the seat plane, avoiding discomfort or foreign body sensation for the driver and passengers; multiple second air bag layers can be set, increasing the height travel of the air bag and increasing the massage intensity.

[0045] Furthermore, the aforementioned car seat airbags can also be used for the massage airbag 12 to achieve an excellent massage effect. However, this embodiment is not intended to limit the selection of the first raised dot airbag 4, the second raised dot airbag 7, the third raised dot airbag 8, and the massage airbag 12.

[0046] The massage areas are all based on the H-point of the car seat cushion (in automotive design and ergonomics, the H-point is a key reference point, also known as the hip point, used to describe the center position of the hip joint when the human body is sitting. It is the core reference for the layout of car seats, pedals, steering wheels, and other components, directly affecting the comfort, visibility, and ease of operation of the driver and passengers). The vertical distance between the geometric center of the first felt plate 3 and the H-point of the car seat cushion is 340mm, and the lateral distance between the geometric centers of the two first felt plates 3 is 140mm. The vertical distance between the second convex air bag 7 and the H-point of the car seat cushion is 205mm, and the lateral distance between the two second convex air bags 7 is 130mm. The vertical distance between the third convex air bag 8 and the H-point of the car seat cushion is 115mm, and the lateral distance between the two third convex air bags 8 is 100mm. The longitudinal distance between the third felt plate 11 and the H-point of the car seat cushion is 90mm, and the lateral distance between the two third felt plates 11 is 170mm.

[0047] By setting up the massage points based on point H, the massage points can be designed to better fit the curves of the human body, resulting in more precise massage positions. The kneading and pinching motions can then be applied precisely to the muscles, meridians, and other parts of the body, leading to a better massage effect.

[0048] refer to Figures 2-4The air supply mechanism includes a first air pump 17 and a second air pump 18 installed inside the seat cushion, and a third air pump 24, a fourth air pump 25, and a silencer bottle 23 installed inside the backrest. An air pump hose G19 is connected to the first air pump 17, and an air pump hose F20 is connected to the second air pump 18. A first three-way quick-connect fitting 21 connects the air pump hose G19 and the air pump hose F20. An air pump hose E22 is connected to another port of the first three-way quick-connect fitting 21, and the other end of the air pump hose E22 is connected to the silencer bottle 23. An air pump hose is connected to the third air pump 24. Pipe A26 is connected to the fourth air pump 25 via air pump pipe B27. A second three-way quick-connect fitting 28 connects air pump pipe A26 and air pump pipe B27. Another port of the second three-way quick-connect fitting 28 is connected to air pump pipe C29. The other end of air pump pipe C29 is connected to a silencer bottle 23. An air pump pipe D30 is connected to the air outlet of the silencer bottle 23. The other end of air pump pipe D30 is connected to a four-way quick-connect fitting 31. A twelve-point massage control valve (marked as the first multi-point massage control valve 14) and an eight-point massage valve are installed on the back of the backrest felt board 1. The first multi-point massage control valve (marked as the second multi-point massage control valve) is installed below the cushion felt plate 2. Another twelve-point massage control valve (marked as the third multi-point massage control valve) is installed below the cushion felt plate 2. The other three interfaces of the four-way quick connector 31 are connected to the first multi-point massage control valve 14, the second multi-point massage control valve 15, and the third multi-point massage control valve 16 through the first control valve air pump pipe 32, the third control valve air pump pipe 34, and the second control valve air pump pipe 33, respectively. Moreover, the first massage air pipe 5 is connected to the first protruding air bag 4. The other end of the first massage air pipe 5 is connected to a three-way pipe. The second massage air bag 7 is connected to two interfaces of the first multi-point massage control valve 14. The second massage air tube 9 is connected to the second protruding air bag 7. The other end of the second massage air tube 9 is connected to the two interfaces of the second multi-point massage control valve 15 through a three-way tube. The third massage air bag 8 is connected to the third massage air tube 10. The other end of the third massage air tube 10 is connected to the two interfaces of the second multi-point massage control valve 15. The massage air bag 12 is connected to the fourth massage air tube 13. The other end of the fourth massage air tube 13 is connected to the two interfaces of the third multi-point massage control valve 16 through a three-way tube.

[0049] With the above setup, the air supply system utilizes four air pumps to ensure sufficient air supply capacity. Two air pumps are installed inside the seat cushion, and the other two are installed inside the backrest. This installation method fully considers the internal space structure of the seat, achieving a rational arrangement of the internal space and avoiding space waste and layout chaos.

[0050] Next, in terms of air path design, a silencer bottle 23 was specially introduced. After the four air pumps are connected in pairs, they are all connected to the silencer bottle 23. The three multi-point massage control valves all receive air from the silencer bottle 23. It can effectively reduce the noise generated when the airflow flows in the air path, significantly improve the comfort during the massage process, and allow users to enjoy the massage without being disturbed by noise.

[0051] Finally, regarding massage control, three multi-point massage control valves (a 12-point massage control valve and an 8-point massage control valve) allow for independent control of the massage on different parts of the seat. This zoned massage design ensures that the different massage zones do not interfere with each other, and users can freely combine various massage modes according to their own needs, greatly enhancing the personalization and comfort of the massage experience.

[0052] In this embodiment, the lengths of each air passage are as follows: the lengths of the first massage air pipe 5 are 103mm, 142mm, and 172mm; the length of the second massage air pipe 9 is 127mm; the length of the third massage air pipe 10 is 148mm; the lengths of the fourth massage air pipe 13 are 222mm, 252mm, and 289mm; the length of the air pump pipe A26 is 368mm; the length of the air pump pipe B27 is 28mm; the length of the air pump pipe C29 is 24mm; the length of the air pump pipe D30 is 41mm; the length of the air pump pipe E22 is 961mm; the length of the air pump pipe F20 is 63mm; the length of the air pump pipe G19 is 59mm; the length of the first control valve air pump pipe 32 is 380mm; the length of the second control valve air pump pipe 33 is 58mm; and the length of the third control valve air pump pipe 34 is 1056mm.

[0053] By using the above settings and selecting pipes of different lengths, a more reasonable pipe layout can be achieved in the car seat cushion, ensuring layout space and smooth air passage. When adjusting the car seat, the adjustment space can be increased, and the anti-interference effect of the massage device can be improved.

[0054] In addition, this device also offers a variety of massage modes:

[0055] 1. Massage points: 4-point tapping on the backrest + 6-point kneading + 6-point tapping on the seat cushion;

[0056] 2. Massage Modes: Includes eight modes (4 regular kneading + 4 tapping kneading) and three intensity levels (high / medium / low). The seat cushion / backrest massage can work independently or simultaneously.

[0057] 3. Massage frequency:

[0058] Pulse massage: The air bag is inflated and deflated at a frequency of 5Hz to 12Hz to achieve a regular, intermittent force on the muscles, meridians and other parts of the body; it simulates the patting action of a human hand to apply massage to the local area.

[0059] Percussion massage: Inflate and deflate the percussion bag at a frequency of 0.5-3Hz to achieve continuous, rhythmic, and repetitive action on the muscles, meridians, and other parts of the body; mimicking the high-frequency percussion movements of a professional massage therapist to perform massage on specific areas.

[0060] Kneading massage: Three kneading air bags are driven to inflate and deflate at a frequency of 0.5-3Hz to form clockwise / counterclockwise rotating massage movements. The kneading and pinching movements act on the muscles, meridians and other parts of the body; simulating the kneading movements of human fingers, it provides a deep, circular massage to the muscle tissue, allowing the muscle fibers to be fully stretched and relaxed.

[0061] 4. Massage cycle: 18 minutes, 8 massage modes (a combination of pulse, kneading, and tapping).

[0062] The implementation principle of this embodiment is as follows:

[0063] Four air pumps supply air, and a silencer bottle 23 is added to the air path to reduce noise. The air is supplied to three different areas through three multi-point massage control valves to achieve air pressure control. By inflating and deflating the first convex air bag 4, the second convex air bag 7, the third convex air bag 8, and the massage air bag 12 at a specific frequency, pulse massage and percussion massage can be achieved, simulating the patting action of a human hand and the high-frequency percussion action of a professional massage therapist, respectively. The first convex air bag 4 or the massage air bag 12, which are distributed in a circle, are cyclically inflated and deflated at a specific frequency to form clockwise / counterclockwise rotating massage action. The kneading and pinching action is applied to the muscles, meridians, and other parts of the human body, simulating the kneading action of human fingers, and performing a deep, circular massage on muscle tissue, so that muscle fibers can be fully stretched and relaxed, thereby achieving a simulated acupressure massage technique. It has a high degree of fit and comfort and is more adaptable to the body curves.

[0064] In summary, this device can simulate the acupressure massage of human fingers and offers a variety of massage modes and combinations thereof, providing a high degree of massage fit and comfort.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
