Massage pulsation generator and massage system for sliding-type automobile seats

Abstract

This disclosure provides a shearing motion type massage pulsation generator and massage system for automobile seats, comprising a first airflow distribution plate and a second airflow distribution plate on the rear of the housing, the first airflow distribution plate having a first exhaust port communicating with the exhaust section, and the second airflow distribution plate having a second exhaust port. The state is adjusted by controlling the rotation of the second airflow distribution plate. When the first and second exhaust ports overlap, gas is discharged from the first and second exhaust ports. When the positions of the first and second exhaust ports are misaligned, airtightness is maintained between the first and second airflow distribution plates. By regularly exhausting a minute flow rate during the supply of air to the gas-using assembly, the stiffness of the gas-using assembly changes in response to changes in internal air pressure, thereby achieving a vibration effect. In this method, since the vibration mode is closely related to the relative position of the first and second airflow distribution plates, which occupy a small space, it is possible to achieve high controllability of the vibration frequency and high comfort.

[0027] Furthermore, terms such as "first," "second," etc., should be understood as merely descriptive and not as to explicitly or implicitly indicate relative importance.

[0028] Furthermore, for the sake of clarity, the drawings show only the parts relevant to the invention. In addition, the features of the embodiments of this disclosure can be combined, as long as there is no contradiction.

[0029] As mentioned in the background technology section, the demand for comfort while riding in a car is increasing as people's living standards improve. To meet this need, automotive developers are integrating massage devices into car seats so that passengers can experience a massage while riding.

[0030] The operation of a conventional car seat vibration massage device is as follows:

[0031] The air pump is connected to the airbags via an air supply tube and fills the airbags with gas. A vibration motor is installed between the air pump and each airbag. When the vibration function is activated, the vibration motors vibrate at different vibration frequencies according to the selected massage mode, and the generated vibrations are transmitted to the human body through the airbags, achieving a massage effect.

[0032] Vibration systems using vibration motors are affected by the inherent characteristics of the vibration motors themselves. The vibration frequency of vibration motors is usually 100 Hz or higher, which is too fast compared to the 8-15 Hz vibration frequency that the human body finds comfortable, resulting in inferior comfort. Furthermore, because each airbag requires its own vibration motor, it takes up a large amount of space in the car seat and is difficult to control.

[0033] In view of the above, to solve this problem, embodiments of the present disclosure provide a massage pulsation generator and massage system for a sliding-type automobile seat, which are described in detail below.

[0034] The core idea of ​​this disclosure is to improve the method of generating massage pulsations in automobile seats by filling the airbag with gas and rotating two airflow distribution plates with holes in them while they are brought into contact with each other. This causes repeated overlapping and misalignment of the holes on the two airflow distribution plates, resulting in exhaust at a constant frequency and generating vibrations in the airbag.

[0035] The operating principle of this disclosure is as follows: An air pump is connected to an airbag, and the other end of the airbag is connected to the housing of a pulsation generator via an exhaust section. Inside the housing are a first airflow distribution plate and a second airflow distribution plate, which abut each other and each has an exhaust port. The exhaust port on the first airflow distribution plate is connected to an exhaust section, and the exhaust port on the second airflow distribution plate rotates with the second airflow distribution plate. When the two exhaust ports partially overlap or completely overlap, gas is discharged from the two exhaust ports, and when they are misaligned, gas is not discharged. By rotating the second airflow distribution plate at high speed with a motor, the overlap and misalignment of the two exhaust ports are rapidly repeated. As a result, the airbag exhausts at a constant frequency during the air supply process, generating a vibration effect.

[0036] As shown in Figures 1 to 7 and Figure 10, the shearing motion type massage pulsation generating device for automobile seats according to this disclosure includes a housing 1, a first airflow distribution plate 2, and a second airflow distribution plate 3.

[0037] The housing 1 has a first space inside, and the housing 1 is provided with at least one exhaust section 5, which is configured to connect the gas usage assembly 4 with the first space.

[0038] The first airflow distribution panel 2 is fixed within the first space and abuts against the inner wall of the housing 1 on the side closest to the exhaust section 5, and the first airflow distribution panel 2 is provided with a first exhaust port 6 corresponding to the exhaust section 5.

[0039] The second airflow distribution panel 3 is located within the first space, abuts against the first airflow distribution panel 2, is rotatable relative to the housing 1, and is provided with at least one second exhaust port 7.

[0040] The second exhaust port 7 has a first position and a second position. When the second exhaust port 7 is in the first position, it partially or completely overlaps with the first exhaust port 6, and is configured so that the gas in the gas usage assembly 4 is discharged from both the first exhaust port 6 and the second exhaust port 7. When the second exhaust port 7 is in the second position, it is completely offset from the first exhaust port 6, and is configured so that the gas in the gas usage assembly 4 is prevented from being discharged from the second exhaust port 7.

[0041] Specifically, as shown in Figure 10, the air pump 21 continuously fills the gas use assembly 4 with gas, which flows into the gas use assembly 4 through the pipe 23 via the valve 16, and another pipe connected to the gas use assembly 4 communicates with the exhaust section 5. When the second airflow distributor 3 is in the first position, the gas discharge rate in the gas use assembly 4 exceeds the air supply rate, causing the air pressure inside the gas use assembly 4 to decrease and the gas use assembly 4 to contract. When the second airflow distributor 3 is in the second position, gas is no longer discharged from the gas use assembly 4, and the air pressure continuously increases due to the air supply from the air pump 21, causing the gas use assembly 4 to expand. The dotted box represents the control device 22, which is configured to control the supply and exhaust of the airbag by controlling the opening and closing of the valve 16. The dotted arrow indicates the direction of gas flow.

[0042] By controlling the rotation of the second airflow distribution plate 3, the overlap and misalignment of the second exhaust port 7 and the first exhaust port 6 are repeated, and by repeatedly switching between the first and second positions of the second airflow distribution plate 3, the air pressure inside the gas usage assembly 4 can be repeatedly adjusted. When a person leans against the gas usage assembly 4, they can feel the repeated expansion and contraction process by the gas usage assembly 4. The repeated expansion and contraction by the gas usage assembly 4 provides a vibratory massage effect.

[0043] As the second airflow distribution panel 3 rotates, each second exhaust port 7 aligns with at least one first exhaust port 6.

[0044] According to the above method, by rotating the second airflow distributor at high speed, the effect of exhausting gas at a constant frequency during the gas filling process of the airbag can be achieved. The repeated rise and fall of air pressure within the gas-using assembly 4 adjusts the stiffness of the gas-using assembly 4, thereby achieving a vibratory massage effect.

[0045] In some embodiments, the housing 1 is divided into an upper housing and a lower housing, and the upper and lower housings are detachably connected. Multiple exhaust units 5 are provided in the upper housing, and the detachable connection of the upper and lower housings facilitates the installation of the housing for the sliding motion type massage pulsation generator for automobile seats.

[0046] Furthermore, the shearing motion type massage pulsation generator for automobile seats further includes a transmission assembly and a drive unit 8.

[0047] The transmission assembly is located in the first space and is fixedly connected to the second airflow distribution panel 3.

[0048] The drive unit 8 is fixed to the housing 1, and its drive end penetrates the housing 1 and is fixedly connected to the transmission assembly. The drive unit 8 is configured to control the switching between the first and second positions of the second airflow distribution plate 3 by rotating the transmission assembly and the second airflow distribution plate 3.

[0049] Specifically, the drive unit 8 is a rotary motor.

[0050] In some embodiments, the drive unit 8 rotates the transmission assembly, thereby rotating the second airflow distributor 3 and the second exhaust port 7. This causes repeated overlapping and misalignment of the second exhaust port 7 and the first exhaust port 6, thereby switching between the first and second positions of the second airflow distributor 3.

[0051] Furthermore, the transmission assembly includes a first transmission member 9 and a second transmission member 10. The first transmission member 9 is fixed to the drive end of the drive unit 8, and the second transmission member 10 is detachably attached to the first transmission member 9 and fixedly connected to the second airflow distribution panel 3. The second transmission member 10 is configured to be driven and rotated by the drive unit 8 and the first transmission member 9. The second transmission member 10 is further provided with at least one third exhaust port 18 corresponding to the second exhaust port 7.

[0052] In some embodiments, the first transmission member 9 is fixedly connected to the drive end of the drive unit 8, the second transmission member 10 is detachably connected to the first transmission member 9, and the second airflow distribution panel 3 is fixedly connected to the second transmission member 10. The first transmission member 9, the second transmission member 10, and the second airflow distribution panel 3 rotate simultaneously when driven by the drive unit 8.

[0053] In some embodiments, the second transmission member 10 is designed with a hollow structure to allow gas to flow freely.

[0054] Specifically, the second transmission member 10 is provided with a third exhaust port 18, and the third exhaust port 18 overlaps with the second exhaust port 7, thus enabling gas flow.

[0055] Furthermore, the first transmission member 9 has a first end and a second end, and the second transmission member 10 is provided with a first transmission groove 11. The first end is fixedly connected to the drive unit 8, and the second end is inserted into the first transmission groove 11, with its outer wall in contact with the inner wall of the first transmission groove 11, and is driven by the drive unit 8 to transmit torque to the second transmission member 10, thereby rotating the second airflow distribution plate 3.

[0056] In some embodiments, the second end has a D-shaft structure. By forming the second end into a D-shaft structure and making the shape of the first transmission groove 11 correspond to the D-shaft shape, the D-shaft shaped second end can be inserted into the first transmission groove 11, and torque can be transmitted by the outer wall of the second end contacting the inner wall of the first transmission groove 11.

[0057] Furthermore, as shown in Figures 5 and 6, a second transmission groove 12 is provided at the second end, and the opening of the second transmission groove 12 faces the second airflow distribution plate 3. An elastic member 13 is provided inside the second transmission groove 12, with one end of the elastic member 13 in contact with the inner wall of the first transmission groove 11 and the other end in contact with the inner wall of the second transmission groove 12. The elastic member 13 is configured to cause the second airflow distribution plate 3 to abut against the first airflow distribution plate 2 via the second transmission member 10.

[0058] In some embodiments, the elastic member 13 is a spring.

[0059] Since airtightness must be maintained during the rotation of the second airflow distributor 3 and the first airflow distributor 2 relative to each other, it is necessary to keep them in close contact. In this embodiment, the D-shaft-shaped second end and the first transmission groove 11 are movable relative to each other along a direction parallel to the first direction. The first direction is parallel to the drive end axis direction of the drive unit 8. The elastic member 13 separates the first transmission member 9 and the second transmission member 10 from each other, and since the first transmission member 9 and the drive unit 8 are fixed inside the housing 1, the second transmission member 10 and the second airflow distributor 3 move away from the drive unit 8 along the first direction and towards the first airflow distributor 2. As a result, the first airflow distributor 2 and the second airflow distributor 3 are in close contact and airtightness is maintained.

[0060] In some embodiments, an elastic member 13 is installed in the second transmission groove 12, allowing the first transmission member 9 and the second transmission member 10 to move relative to each other, thereby accommodating housings 1 of various sizes. Even if the length of the housing 1 along the first direction is too long or too short, the elastic member 13 can accommodate the length of the housing 1, and the first airflow distributor 2 and the second airflow distributor 3 can be brought into close contact.

[0061] Furthermore, the housing 1 is provided with an exhaust port 14 that connects the first space with the outside air.

[0062] In some embodiments, the gas in the gas-using assembly 4 is discharged into a first space and then discharged to the outside through an exhaust port 14. A sound-absorbing member 15 is further provided in the exhaust port 14, and the sound-absorbing member 15 is specifically soundproofing cotton. This reduces noise caused by gas movement in the exhaust port 14.

[0063] Furthermore, a sound-absorbing member 15 is provided in the third exhaust port 18, which is configured to reduce noise generated during exhaust.

[0064] In some embodiments, by providing a sound-absorbing member 15 in the second exhaust port 7, noise caused by gas vibration during exhaust can be reduced, and the overall quietness of the structure can be improved.

[0065] Furthermore, as shown in Figures 8 and 9, the second airflow distribution panel 3 is provided with a plurality of second exhaust ports 7, which are arranged along the circumferential direction of the second airflow distribution panel 3 and are configured to control the gas usage assembly 4 to exhaust gas at different frequencies.

[0066] Specifically, the multiple second exhaust ports 7 can be evenly arranged along the second airflow distribution plate 3, or they can be unevenly arranged. These different arrangements allow for different vibration patterns and thus a variety of massage modes.

[0067] In some embodiments, by randomly providing multiple second exhaust ports 7 on the second airflow distribution plate 3, the exhaust of the gas-using assembly 4 can be controlled at different time intervals as the second airflow distribution plate 3 rotates. This allows for control of the vibration frequency of the gas-using assembly 4, thereby achieving massage effects at various frequencies.

[0068] Furthermore, grease is applied between the first airflow distributor 2 and the second airflow distributor 3, and the system is configured to reduce friction between the first airflow distributor 2 and the second airflow distributor 3 while maintaining airtightness between them.

[0069] In some embodiments, the exhaust of the gas-using assembly 4 is adjusted solely by controlling the overlap and misalignment of the first exhaust port 6 and the second exhaust port 7 due to mutual friction between the first airflow distributor 2 and the second airflow distributor 3. Therefore, after prolonged use, wear occurs between the first exhaust port 6 and the second exhaust port 7, causing gas leakage. Accordingly, applying grease can significantly reduce wear between the first airflow distributor 2 and the second airflow distributor 3, thereby improving the lifespan. Furthermore, filling the gap between the first airflow distributor 2 and the second airflow distributor 3 also improves the airtightness between the two.

[0070] The first airflow distribution panel 2 is fixedly connected to the housing 1 with adhesive, and the second airflow distribution panel 3 is fixedly connected to the second transmission member 10 with adhesive.

[0071] As shown in Figure 4, the first airflow distributor 2 is further provided with a regulating groove 19, and the housing 1 is further provided with a regulating projection 20. When attaching the first airflow distributor 2 to the housing 1, adhesive is first applied to the housing 1 or the first airflow distributor 2, and then the first airflow distributor 2 is placed inside the housing 1 so that the regulating projection 20 is positioned within the regulating groove 19. As the adhesive dries, the first airflow distributor 2 and the housing 1 are fixed together.

[0072] The regulating groove 19 and regulating projection 20 facilitate the alignment of the first exhaust port 6 and the exhaust section 5, preventing installation errors and improving installation efficiency.

[0073] Specifically, the arrows in Figure 1 indicate the direction of gas flow during exhaust. The arrows in Figure 2 represent the state in which, as the gas moves from the gas-using assembly 4 to the first exhaust port 6, the first exhaust port 6 and the second exhaust port 7 shift relative to each other, blocking the gas flow and preventing it from being discharged.

[0074] As shown in Figure 10, the car seat massage system according to this embodiment further includes, in addition to the shear-movement type car seat massage pulsation generator according to the above embodiment, a gas usage assembly 4, a control device 22, and a gas supply source assembly. The gas usage assembly 4 is connected to the exhaust section 5 of the shear-movement type car seat massage pulsation generator via a conduit 23 while maintaining airtightness. The control device 22 is in communication with the gas usage assembly 4 and the gas supply source assembly, respectively, via the conduit 23, and is configured to control the supply and exhaust of gas to the gas usage assembly 4. The gas supply source assembly is in communication with the gas usage assembly 4 via the conduit 23 and is configured to fill the gas usage assembly 4 with gas via the conduit 23 through the control device 22.

[0075] Specifically, the gas usage assembly 4 is an airbag, and one or more can be installed as needed. One control device 22 is provided, and inside it is a valve 16 that corresponds one-to-one with the airbag. The gas supply source assembly is an air pump 21.

[0076] The gas supply source assembly continuously delivers gas to pipeline 23, and the gas flows through pipeline 23 to the control device 22. When the air supply path controlled by valve 16 opens, the corresponding airbag is filled.

[0077] The arrangement of the exhaust section 5 in Figure 7 saves space in the direction parallel to the drive end rotation axis of the drive unit 8, thereby improving the spatial adaptability when installing a sliding motion type car seat massage pulsation generator inside the seat.

[0078] Figures 8 and 9 show two different arrangements for the second exhaust port 7. Depending on the arrangement, the exhaust frequency of the gas-using assembly 4 by the second airflow distribution panel 3 also differs, resulting in the gas-using assembly 4 vibrating at different frequencies and achieving a variety of massage effects. The arrangement of the second exhaust port 7 can be adjusted as needed.

[0079] In Figure 10, the direction of the arrow indicates the rotation direction of the second airflow distributor 3.

[0080] Figure 11 shows the waveform of the air pressure inside an airbag during operation. The horizontal axis t(s) represents time in seconds. The vertical axis P(kPa) represents the air pressure inside the airbag in kilopascals. During the process of filling the airbag via the gas supply assembly, the air pressure inside the airbag and the change in airbag stiffness due to airbag deformation are proportional. The higher the air pressure inside the airbag, the stiffer it becomes, and the lower the air pressure, the stiffer it becomes. Intermittent exhaust by the shear-type car seat massage pulsation generator causes fluctuations in air pressure and changes in airbag stiffness, resulting in vibration in the airbag. As is clear from the waveform, the shear-type car seat massage pulsation generator operates during air supply, causing the air pressure inside the airbag to fluctuate as shown in the waveform.

[0081] The above description is merely a description of preferred embodiments of the present disclosure and the principles of the technology used. Those skilled in the art should understand that the scope of the invention as disclosed is not limited to any specific combination of the above-described technical features, but also includes other technical features formed by any combination of the above-described technical features or their equivalents, without departing from the spirit of the invention. For example, such technical features could be obtained by substituting the above-described features with similar functional technical features disclosed in this disclosure. [Industrial applicability]

[0082] The shearing motion type massage pulsation generator and massage system for automobile seats according to this disclosure achieve a vibration effect by regularly exhausting a minute flow rate of air into the gas-using assembly during air supply, causing the stiffness of the gas-using assembly to change in response to changes in internal air pressure. In this method, since the vibration mode is related to the relative position of the first airflow distribution plate and the second airflow distribution plate, which occupy a small space, it is possible to achieve high controllability of the vibration frequency and produce high comfort.
