Staggered automobile seat massage pulsation generator and massage system

Abstract

The present disclosure provides a staggered automobile seat massage pulsation generator and a massage system. The staggered automobile seat massage pulsation generator comprises a first gas distribution disc and a second gas distribution disc arranged on a back portion of a housing. A first gas vent hole in communication with a gas venting end is provided in the first gas distribution disc, and a second gas vent hole is provided in the second gas distribution disc. The second gas distribution disc is controlled to rotate, thereby adjusting the state of the second gas distribution disc. When the first gas vent hole is aligned with the second gas vent hole, gas is discharged from the first gas vent hole and the second gas vent hole. When the first gas vent hole and the second gas vent hole are staggered, gas tightness is maintained between the first gas distribution disc and the second gas distribution disc. In an inflation process of a gas-using assembly, gas is regularly vented at a small flow rate, such that the gas-using assembly generates a change in hardness on the basis of a change in the air pressure therein, thereby achieving a vibration effect. In this way, since a vibration mode is closely related to the relative position of the first gas distribution disc and the second gas distribution disc which occupy a smaller space, the controllability of the vibration frequency is high, and thus, a high degree of comfort can be created.

During inflation, the air component releases air at a regular, low flow rate. The air component produces changes in hardness and softness based on the changes in air pressure, thereby achieving a vibration effect.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all of them. Generally, the components of the embodiments of the present disclosure described and shown in the drawings herein can be arranged and designed in various different configurations.

[0053] Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the present disclosure as claimed, but merely represents selected embodiments of the present disclosure. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0054] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0055] In the description of the present disclosure, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present disclosure.

[0056] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0057] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. It should be noted that, in the absence of conflict, the features in the embodiments of the present disclosure can be combined with each other.

[0058] As mentioned in the background art, with the improvement of people's living standards, there is a higher demand for the riding experience when riding in a car. In order to experience the massage process during the ride in the car, automobile R&D personnel have installed massage devices on car seats to meet the demand.

[0059] The working process of the existing car seat vibration massager is:

[0060] The air pump connects to the air bags via air pipes and inflates them. A vibration motor is installed between the air pump and each air bag. When the vibration function is turned on, the vibration motor vibrates at different frequencies depending on the selected massage mode, and the vibration is transmitted to the body through the air bags to achieve a massage effect.

[0061] The method used to achieve vibration using a vibration motor is affected by its inherent properties. Since vibration motors typically have a frequency of over 100 Hz, compared to the comfortable 8-15 Hz frequency, this is too fast and less comfortable. Furthermore, placing a separate vibration motor for each airbag takes up considerable space within the car seat, making control more difficult.

[0062] In view of this, the staggered car seat massage pulsation generator and massage system provided in the embodiments of the present disclosure can solve this problem, which will be described in detail below.

[0063] The core concept of the present invention is to improve the way in which pulsating massage of car seats occurs. While the air bag is inflated, two air distribution plates with holes are used to contact each other and produce relative rotation. The holes on the two air distribution plates are repeatedly aligned and misaligned, and air is deflated at a certain frequency to achieve the vibration of the air bag.

[0064] The working principle of the present invention includes: the air pump is connected to the air bag, and the other end of the air bag is connected to the shell of the pulsation generator through the air release end. A first air distributor and a second air distributor are provided inside the shell, which are in conflict with each other and both have air release holes. The air release holes on the first air distributor are connected to the air release end, and the air release holes on the second air distributor rotate with the second air distributor. When the two air release holes partially overlap or completely overlap, the gas is discharged through the two air release holes; when they are misaligned with each other, the gas is no longer discharged. The second air distributor is controlled by a motor to rotate rapidly, so that the two air release holes are quickly and repeatedly aligned and misaligned, so that the air bag can be deflated at a certain frequency during the inflation process to produce a vibration effect.

[0065] Referring to Figures 1 to 7 and 10 , the present disclosure provides a staggered car seat massage pulsation generator, comprising:

[0066] The housing 1 has a first space therein and is provided with at least one air release end 5; the air release end 5 is configured to connect the air-generating assembly 4 and the first space;

[0067] The first gas distribution plate 2 is fixedly installed in the first space and abuts against the inner wall of the housing 1 near the gas discharge end 5; the first gas distribution plate 2 is provided with a first gas discharge hole 6 corresponding to the gas discharge end 5;

[0068] A second gas distribution plate 3 is disposed in the first space and contacts the first gas distribution plate 2 ; the second gas distribution plate 3 can rotate relative to the housing 1 ; at least one second air leakage hole 7 is formed on the second gas distribution plate 3 ;

[0069] The second air leakage hole 7 has a first state and a second state; when the second air leakage hole 7 is in the first state, the second air leakage hole 7 partially overlaps or completely overlaps with the first air leakage hole 6, and is configured so that the gas in the gas component 4 is discharged from the first air leakage hole 6 and the second air leakage hole 7; when the second air leakage hole 7 is in the second state, the second air leakage hole 7 is completely misaligned with the first air leakage hole 6, and is configured to prevent the gas in the gas component 4 from being discharged from the second air leakage hole 7.

[0070] Specifically, referring to Figure 10, the air pump 21 continuously inflates the gas component 4, and the gas enters the gas component 4 through a pipe 23 via the air valve 16. Another pipe connected to the gas component 4 is connected to the deflation end 5. When the second gas distribution disk 3 is in the first state, the gas discharge speed in the gas component 4 is greater than the inflation speed, the air pressure in the gas component 4 decreases, and the gas component 4 relaxes. When the second gas distribution disk 3 is in the second state, the gas in the gas component 4 is no longer discharged. Due to the inflation action of the air pump 21, the air pressure continues to increase, and the gas component 4 is tightened. The dotted box represents the controller 22, which is configured to control the opening and closing of the air valve 16 to control the inflation and deflation of the air bag. The dotted arrow indicates the direction of gas movement.

[0071] By controlling the rotation of the second air distribution disk 3, the second air relief hole 7 is repeatedly aligned and offset with the first air relief hole 6, and the second air distribution disk 3 is repeatedly switched between the first and second positions, the air pressure within the air component 4 can be repeatedly adjusted. When a person leans against the air component 4, they can feel the air component 4 repeatedly tightening and relaxing. The repeated tightening and relaxing of the air component 4 creates a vibration massage effect.

[0072] When the second air distribution plate 3 rotates, each second air leakage hole 7 will overlap with at least one first air leakage hole 6 .

[0073] By controlling the rapid rotation of the second air distribution disk, the air bag can be deflated at a certain frequency during the inflation process. As the air pressure in the air component 4 rises and falls cyclically, the hardness of the air component 4 is adjusted, ultimately achieving a vibration massage effect.

[0074] In some embodiments, the shell 1 is divided into an upper shell and a lower shell, and the upper shell and the lower shell are detachably connected. The upper shell is provided with multiple air discharge ends 5. The detachable connection between the upper and lower shells facilitates the installation of the shell of the staggered car seat massage pulsation generator.

[0075] Furthermore, the staggered car seat massage pulsation generator also includes:

[0076] The transmission assembly is arranged in the first space and is fixedly connected to the second gas distribution plate 3;

[0077] The driving device 8 is fixedly mounted on the shell 1. The driving end of the driving device 8 passes through the shell 1 and is fixedly connected to the transmission assembly. It is configured to drive the transmission assembly and the second gas distribution disk 3 to rotate, and control the second gas distribution disk 3 to switch between the first state and the second state.

[0078] Specifically, the driving device 8 is a rotary electric motor.

[0079] In some embodiments, the driving device 8 drives the transmission assembly to rotate, and then drives the second air distribution plate 3 and the second air leakage hole 7 to rotate, so that the second air leakage hole 7 is repeatedly aligned and misaligned with the first air leakage hole 6 to achieve the effect of switching the second air distribution plate 3 between the first state and the second state.

[0080] Furthermore, the transmission assembly includes:

[0081] A first transmission member 9, the first transmission member 9 is fixedly mounted on the driving end of the driving device 8;

[0082] The second transmission member 10 is detachably mounted on the first transmission member 9; the second transmission member 10 is fixedly connected to the second gas distribution plate 3 and is configured to drive the second gas distribution plate 3 to rotate under the drive of the driving device 8 and the first transmission member 9;

[0083] The second transmission member 10 is further provided with at least one third air leakage hole 18 corresponding to the second air leakage hole 7 .

[0084] In some embodiments, the first transmission member 9 is fixedly connected to the driving end of the driving device 8, and the second transmission member 10 is detachably connected to the first transmission member 9; and the second gas distribution disk 3 is fixedly connected to the second transmission member 10, and the first transmission member 9, the second transmission member 10 and the second gas distribution disk 3 rotate together under the drive of the driving device 8.

[0085] In some embodiments, the second transmission member 10 is designed as a hollow structure to facilitate free flow of gas.

[0086] Specifically, a third air leakage hole 18 is formed on the second transmission member 10 , and the third air leakage hole 18 is aligned with the second air leakage hole 7 and is configured to allow gas to flow.

[0087] Furthermore, the first transmission member 9 has a first end and a second end; the second transmission member 10 is provided with a first transmission groove 11;

[0088] The first end is fixedly connected to the driving device 8; the second end is inserted into the first transmission groove 11; the outer wall of the second end abuts against the inner wall of the first transmission groove 11, and is configured to transmit torque to the second transmission member 10 under the drive of the driving device 8, driving the second air distribution plate 3 to rotate.

[0089] In some embodiments, the second end is a flat shaft structure. By designing the second end as a flat shaft structure and matching the shape of the first transmission groove 11 with the flat shaft, the second end in the flat shaft shape can be inserted into the first transmission groove 11, and the outer wall of the second end abuts against the inner wall of the first transmission groove 11 to transmit torque.

[0090] Furthermore, referring to FIG5 and FIG6 , a second transmission groove 12 is further provided at the second end; the opening of the second transmission groove 12 faces the second gas distribution plate 3;

[0091] An elastic member 13 is provided in the second transmission groove 12; one end of the elastic member 13 abuts against the inner wall of the first transmission groove 11, and the other end abuts against the inner wall of the second transmission groove 12, and is configured to drive the second air distribution plate 3 to abut against the first air distribution plate 2 through the second transmission member 10.

[0092] In some embodiments, the elastic member 13 is a spring.

[0093] The second air distribution disk 3 and the first air distribution disk 2 need to maintain air tightness during their mutual rotation, so the two need to be in close contact with each other. In this embodiment, the second end of the flat shaft and the first transmission groove 11 can move relative to each other in a direction parallel to the first direction. The first direction is parallel to the axis direction of the driving end of the driving device 8. The elastic member 13 is used to drive the first transmission member 9 and the second transmission member 10 away from each other. Since the first transmission member 9 and the driving device 8 are both fixed inside the shell 1, the second transmission member 10 and the second air distribution disk 3 move along the first direction away from the driving device 8 and move toward the direction close to the first air distribution disk 2, so that the first air distribution disk 2 and the second air distribution disk 3 are in close contact and maintain air tightness.

[0094] In some embodiments, an elastic member 13 is disposed within the second transmission groove 12 to allow relative movement between the first transmission member 9 and the second transmission member 10, thereby accommodating various sizes of housing 1. Whether the housing 1 is longer or shorter along the first direction, the elastic member 13 can adapt to the length of the housing 1, ensuring close contact between the first and second gas distribution plates 2 and 3.

[0095] Furthermore, the housing 1 is provided with an exhaust hole 14 , which is configured to communicate with the first space and the external air.

[0096] In some embodiments, after the gas in the gas assembly 4 is discharged into the first space, it moves to the outside through the exhaust hole 14. A silencer 15 is also provided at the exhaust hole 14, specifically a silencer cotton, which can reduce the noise generated by the gas movement at the exhaust hole 14.

[0097] Furthermore, a silencer 15 is provided at the third air leakage hole 18, configured to reduce noise generated during exhaust.

[0098] In some embodiments, a silencer 15 is provided at the second air vent 7 to reduce the noise generated by gas vibration during exhaust and improve the quietness of the overall structure.

[0099] Furthermore, referring to FIG8 to FIG9 , a plurality of second air leakage holes 7 are provided on the second air distribution plate 3 ;

[0100] The plurality of second air leakage holes 7 are distributed along the circumference of the second air distribution plate 3 and are configured to control the air-using component 4 to leak air at different frequencies.

[0101] Specifically, the distribution of the plurality of second air release holes 7 along the second air distribution plate 3 can be uniform or uneven. Arranged in different distribution modes, different vibration modes can be achieved, thus achieving different modes of massage.

[0102] In some embodiments, a plurality of second air release holes 7 are randomly opened on the second air distribution disk 3, which can control the air release of the air component 4 at different time intervals during the rotation of the second air distribution disk 3, control the vibration frequency of the air component 4, and ultimately achieve massage effects of different frequencies.

[0103] Furthermore, grease is applied between the first gas distributor 2 and the second gas distributor 3 to reduce friction between the first gas distributor 2 and the second gas distributor 3 while maintaining airtightness between the first gas distributor 2 and the second gas distributor 3 .

[0104] In some embodiments, since the air release of the regulating gas assembly 4 is adjusted to the alignment or misalignment of the first and second air release holes 6 and 7 solely through friction between the first and second air release plates 2 and 3, prolonged use can lead to wear between the first and second air release holes 6 and 7, resulting in air leakage. Therefore, applying grease can significantly reduce wear between the first and second air release plates 2 and 3, extending their service life. It can also fill the gap between the first and second air release plates 2 and 3, improving the airtightness between the first and second air release plates 2 and 3.

[0105] The first air distributor plate 2 and the housing 1 are fixedly connected by glue, and the second air distributor plate 3 and the second transmission member 10 are fixedly connected by glue.

[0106] Referring to Figure 4 , the first gas distributor 2 is further provided with a limiting groove 19, and the housing 1 is further provided with a limiting protrusion 20. To install the first gas distributor 2 on the housing 1, glue is first applied to the housing 1 or the first gas distributor 2. The first gas distributor 2 is then placed within the housing 1, with the limiting protrusion 20 positioned within the limiting groove 19. As the glue dries, the first gas distributor 2 and the housing 1 are secured.

[0107] The limiting groove 19 and the limiting protrusion 20 facilitate alignment of the first air leakage hole 6 and the air leakage end 5, thereby preventing installation errors and improving installation efficiency.

[0108] Specifically, the arrow in Figure 1 indicates the direction of gas flow during deflation. The arrow in Figure 2 indicates that when gas moves from the gas component 4 to the first deflation hole 6, the first deflation hole 6 and the second deflation hole 7 are misaligned, and the gas is blocked and no longer discharged.

[0109] 10 , this embodiment provides a car seat massage system, including the staggered car seat massage pulsation generator of the above embodiment;

[0110] The car seat massage system also includes:

[0111] The air component 4 is connected to the air discharge end 5 of the staggered car seat massage pulsation generator through a pipeline 23 and is kept airtight;

[0112] The controller 22 is connected to the gas component 4 and the gas source component through the pipeline 23, and is configured to control the charging and discharging of the gas component 4;

[0113] The air source assembly and the air-using assembly 4 are connected to each other through a pipeline 23 ; the air source assembly is configured to inflate the air-using assembly 4 through the pipeline 23 via the controller 22 .

[0114] Specifically, the gas component 4 is an air bag, and one or more can be provided according to the design; the controller 22 is provided with one, and an air valve 16 is provided inside the controller 22, and corresponds one to one with the air bag; the gas source component is an air pump 21.

[0115] The gas source assembly continuously blows gas into the pipeline 23, and the gas enters the controller 22 through the pipeline 23. When the inflation gas path controlled by the gas valve 16 is opened, the corresponding air bag is inflated.

[0116] The arrangement of the air release end 5 in FIG7 can save space in a direction parallel to the rotation axis of the driving end of the driving device 8, so as to improve the spatial adaptability of the staggered car seat massage pulsation generator when arranged in the seat.

[0117] Figures 8 and 9 show two different arrangements of the second air vents 7. These arrangements allow the second air distribution plate 3 to control the exhaust frequency of the air assembly 4, thereby achieving different massage effects by vibrating the air assembly 4 at different frequencies. The arrangement of the second air vents 7 can be adjusted according to design requirements.

[0118] In FIG. 10 , the arrow direction indicates the rotation direction of the second gas distributor 3 .

[0119] Figure 11 shows a waveform of the airbag pressure during operation; the horizontal axis, t(s), represents time in seconds; the vertical axis, P(kPa), represents the airbag internal pressure in kilopascals. During inflation of the airbag via the air source assembly, the internal air pressure is proportional to the change in bag hardness caused by bag deformation. Higher bag pressure increases bag hardness, while lower pressure decreases bag hardness. Intermittent deflation of the pulsator causes air pressure fluctuations, which in turn causes the bag to vibrate. The waveform indicates that the pulsator's operation during inflation can cause repeated fluctuations in airbag pressure.

[0120] The above description is merely a preferred embodiment of the present disclosure and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this disclosure. Industrial Applicability

[0121] This disclosure provides a staggered car seat massage pulsator and massage system. During the inflation process, the air component is regularly deflated at a low flow rate. The air component produces varying degrees of softness and hardness based on the pressure changes within it, thereby achieving a vibration effect. This method achieves a high degree of controllability of the vibration frequency, as the vibration mode is closely linked to the relative positions of the first and second air distributors, which occupy a smaller space, resulting in a higher level of comfort.
