DETAILED DESCRIPTION

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] As mentioned in the background technology, 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 and added vibration functions to meet the demand.

[0065] The working process of existing car seat vibration massagers is as follows: an air pump connects to the air bags through an air pipe and inflates the air bags. A vibration motor is installed between the air pump and each air bag. When the vibration function is turned on, the vibration motor will vibrate at different frequencies according to the selected massage mode, and the vibration is transmitted to the human body through the air bag to achieve a massage effect. The way in which the vibration motor is used to achieve vibration is affected by the inherent properties of the vibration motor itself. Since the vibration frequency of the vibration motor is generally above 100 Hz, the vibration is too fast compared to the vibration frequency of 8-15 Hz that the human body feels comfortable, and the comfort is poor. In addition, the placement of a vibration motor in each air bag takes up a lot of space in the car seat, making it difficult to control.

[0066] In view of this, a magnetic valve type 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.

[0067] The core concept of the present disclosure is to improve the control process of charging and deflating the gas-using component, continuously inflate the gas-using component, adjust the deflation frequency, and vibrate the gas component to ultimately achieve a vibration effect.

[0068] The operating principle of the present invention includes: an air source assembly connected to a gas-using assembly, the other end of which is connected to the housing of a pulsation generator via a vent port. Within the housing are a valve assembly configured to control the venting of the gas-using assembly and a permanent magnet configured to control the opening of the valve assembly. The permanent magnet is secured to the drive end of the drive assembly via a transmission member and is configured to rotate under the drive assembly's drive. The fast-rotating drive assembly controls the rapid rotation of the permanent magnet mounted on the transmission member.

[0069] When a permanent magnet approaches the valve core, it attracts the ferromagnetic valve core, opening it and deflating the airbag. When the magnet moves away from the valve core, the valve core returns to its original position via an elastic member. Rapid rotation of the drive assembly repeatedly opens and closes the valve core, allowing the airbag to deflate intermittently during inflation, creating a vibrating effect.

[0070] Reference formula (1) is the formula for calculating the gravitational force between the magnetic field source and the attracted object.

[0071] Among them, F represents gravity, K represents a constant measured based on actual experimental scenarios, m represents the magnetic moment of the magnetic field source, and d represents the distance between the magnetic field source and the attracted object.

[0072] Please refer to Figures 1, 2, and 3. The present disclosure provides a magnetic valve type car seat massage pulsation generator, comprising:

[0073] The shell 1 has a first space inside, and at least one air release end 5 is fixed on the shell 1; the air release end 5 is configured to connect the gas component 4 and the first space; the valve body assembly, the valve body assembly is provided with at least one and is all arranged in the first space, and the valve body assembly corresponds to the air release end 5 one by one; the valve body assembly includes a valve core 7, the valve core 7 abuts the air release end 5, and the valve core 7 is a soft magnetic material; the permanent magnet 3, there is at least one permanent magnet 3 and is installed in the shell 1; the permanent magnet 3 moves in the first space; the valve core 7 has a first state and a second state; when the valve core 7 is in the first state, the permanent magnet 3 approaches the valve core 7 and attracts the valve core 7, driving the valve core 7 to separate from the air release end 5, and the valve body assembly is opened, and is configured to discharge the gas in the gas component 4 from the air release end 5; when the valve core 7 is in the second state, the permanent magnet 3 is away from the valve core 7, the valve core 7 is reset, and the valve body assembly is closed, and is configured to prevent the gas in the gas component 4 from being discharged from the air release end 5.

[0074] In this embodiment, the permanent magnet 3 is used to attract the valve core 7, controlling the valve assembly to open, thereby allowing gas to be discharged through the gas release end 5. By controlling the permanent magnet 3 to rapidly perform circular motion within the first space, the valve assembly can be controlled to rapidly switch states. During the inflation process of the gas component 4, gas is released at a regular, small flow rate. The gas component 4 experiences changes in hardness and softness due to the changes in the gas volume within the gas component 4, thereby achieving a vibration effect.

[0075] Specifically, the soft magnetic material is iron, cobalt or nickel or an alloy containing iron, cobalt or nickel.

[0076] In some embodiments, the housing 1 is divided into an upper housing and a lower housing, the upper housing is provided with a plurality of air release ports 5, and the upper and lower housings are detachably connected. The upper housing has a plurality of mounting holes, and the upper and lower housings are fixed by bolts.

[0077] Furthermore, it also includes: a transmission assembly, the transmission assembly is arranged in the first space, the permanent magnet 3 is fixedly mounted on the transmission assembly, and the transmission assembly is configured to drive the permanent magnet 3 to rotate, thereby controlling the valve core 7 to switch between the first state and the second state; a driving device 8, the driving device 8 is fixedly mounted on the shell 1, and the driving end of the driving device 8 passes through the shell 1 and is fixedly connected to the transmission assembly, and is configured to drive the transmission assembly to rotate, and control the valve core 7 to switch between the first state and the second state through the transmission assembly.

[0078] Furthermore, the transmission assembly includes: a transmission member 2, as shown in Figures 9 and 12, the transmission member 2 is disc-shaped and fixedly connected to the driving end of the driving device 8; the permanent magnet 3 is completely embedded in the transmission member 2, or partially exposed and installed on the outer wall of the transmission member 2 perpendicular to the rotation axis, and the transmission member 2 drives the permanent magnet 3 to rotate so that it approaches or moves away from the valve core 7.

[0079] In some embodiments, as shown in FIG5 , the transmission member 2 is cylindrical and fixedly connected to the driving end of the driving device 8 . The transmission member 2 rotates under the drive of the driving device 8 . The permanent magnet 3 is disposed on the outer wall of the transmission member 2 parallel to the rotation axis. The transmission member 2 drives the permanent magnet 3 to rotate toward or away from the valve core 7 . Specifically, the driving device 8 is a motor.

[0080] Specifically, as the permanent magnet 3 rotates with the transmission member 2, it moves to a position close to or facing the valve body assembly. The valve core 7, made of a soft magnetic material, moves closer to the permanent magnet 3 under the influence of the magnetic field of the permanent magnet 3. At this point, the valve core 7 is in the first position and remains open. The valve body assembly no longer abuts the vent port 5, allowing the gas in the degassing assembly 4 to be discharged through the vent port 5.

[0081] In some embodiments, the rotation axis of the transmission member 2 is parallel to the opening of the vent end 5. The transmission member 2 is disc-shaped, and the permanent magnet 3 is either fully embedded in the transmission member 2 or partially exposed and mounted on the outer wall of the transmission member 2 perpendicular to its rotation axis. The transmission member 2 rotates under the drive device 8, thereby driving the permanent magnet 3 to rotate. When the permanent magnet 3 approaches or faces the valve core 7, the valve assembly is attracted to open and switch to the first state. When the permanent magnet 3 moves away from the valve assembly, the valve assembly remains closed and switches to the second state.

[0082] Specifically, the permanent magnet 3 can be completely embedded in the transmission member 2, that is, the permanent magnet 3 cannot be observed from the outside of the transmission member 2. The permanent magnet 3 can also be partially exposed on the surface of the transmission member 2, that is, the surface of the permanent magnet 3 can be observed from the outside of the transmission member 2.

[0083] Furthermore, the transmission member 2 is cylindrical, the permanent magnets 3 are distributed on the outer wall of the transmission member 2 , and during the rotation of the transmission member 2 , the rotation trajectory of the permanent magnets 3 passes through the position of the valve core 7 .

[0084] In some embodiments, the rotation axis of the transmission member 2 is perpendicular to the opening direction of the vent end 5. The transmission member 2 is cylindrical, and the permanent magnets 3 are distributed on the sidewalls of the transmission member 2 parallel to the rotation axis of the transmission member 2. This is specifically shown in Figure 5. Its rotation direction is perpendicular to the movement direction of the valve core 7. During rotation, the cylindrical transmission member 2 drives the permanent magnets 3 to switch the valve core 7 between the first and second states.

[0085] Furthermore, referring to Figures 9, 10, and 12, at least one counterweight 17 is further provided on the transmission member 2, and the counterweight 17 and the permanent magnet 3 are evenly arranged along the circumference of the transmission member 2. In some embodiments, a plurality of permanent magnets 3 and a plurality of counterweights 17 are randomly arranged along the circumference of the transmission member 2. This allows the permanent magnets 3 to rotate with the transmission member 2, utilizing the different intervals between the permanent magnets 3 to control the time interval at which the valve body assembly is attracted by the permanent magnet 3, and ultimately achieves the process of controlling the degassing of the gas component 4 at different intervals.

[0086] By adjusting the intervals between the permanent magnets 3, it is possible to control the deflation of the gas component 4 at different frequencies, and ultimately achieve vibration massage effects at different frequencies.

[0087] In order to prevent the transmission member 2 from being unstable due to centrifugal action during rotation, a counterweight 17 is provided to make the transmission member 2 more stable during rotation.

[0088] Further, referring to Figures 1, 2, 6 and 7, the valve body assembly includes: a fixing member 6, which is fixedly installed in the first space; and a valve core 7 installed on the fixing member 6 and movable relative to the fixing member 6.

[0089] Specifically, the fixing member 6 is provided with a positioning column 22, which is configured to be pre-fixed with the positioning hole 18 on the housing 1 during installation to ensure an accurate installation position.

[0090] Furthermore, as shown in Figures 4 and 20, the valve core 7 includes: a valve core body 71 and a first boss 72 provided on the side of the valve core body 71 away from the air leak end 5; when the valve core 7 is in the first state, the end of the first boss 72 away from the air leak end 5 extends out of the fixing member 6, and when the valve core 7 is in the second state, the end of the first boss 72 away from the air leak end 5 extends out of the fixing member 6 or is flush with the end of the fixing member 6 away from the air leak end 5.

[0091] Specifically, the valve core 7 can move in a direction parallel to the air release end 5 .

[0092] When the valve core 7 is disengaged from the deflation end 5, the valve body assembly is in the first position. When the valve core 7 is in contact with the deflation end 5, the valve body assembly is in the second position. By adjusting the position of the valve core 7, the air component 4 can be switched between the inflation and deflation states. Repeated adjustment of the position of the valve core 7 allows the air component 4 to be repeatedly tightened and loosened.

[0093] The valve body assembly further includes an elastic member 10, one end of which abuts the connection between the valve core body 71 and the first boss 72, and the other end of which abuts the fixing member 6. The elastic member 10 is configured to drive the valve core 7 to move to the second position when the valve core 7 is away from the deflation end 5 and the permanent magnet 3 is away from the valve core 7. In some embodiments, the elastic member 10 is a spring. The valve core 7 is made of a soft magnetic material.

[0094] When the elastic member 10 is provided so that the permanent magnet 3 is away from the valve core 7 , the valve core 7 can automatically return to a state of contact with the air release end 5 , thereby preventing gas from being discharged from the gas component 4 .

[0095] The magnetic force exerted by the permanent magnet 3 on the valve body assembly is greater than the maximum elastic force of the elastic member 10. Therefore, when the permanent magnet 3 approaches the valve body assembly, the valve core 7 overcomes the elastic force of the elastic member 10 under the action of the magnetic force and moves away from the venting end 5, allowing the gas in the gas assembly 4 to be discharged from the venting end 5.

[0096] In some embodiments, an abutment member 9 is provided at one end of the valve core 7 near the air release end 5, and the abutment member 9 is configured to abut against the air release end 5 to ensure the sealing of the air release end 5. Specifically, the abutment member 9 is made of rubber or silicone to ensure airtightness when the abutment member 9 abuts against the air release end 5.

[0097] When the valve body assembly is in the second position, the abutment member 9 abuts against the deflated end 5 and maintains an airtight seal, thereby preventing gas from being discharged. Since the abutment member 9 and the deflated end 5 need to be repeatedly controlled to abut and disengage during operation, the use of wear-resistant materials can extend the service life of the valve body assembly.

[0098] Furthermore, the valve body assembly is also provided with a first ventilation groove 19; the first ventilation groove 19 is provided on the fixing member 6 or on the valve core body 71; the first ventilation groove 19 is configured to allow the gas discharged from the deflation end 5 to move from the first ventilation groove 19 to the first space.

[0099] Specifically, as shown in Figures 1, 2, 21 and 22, a first ventilation groove 19 is provided between the valve core 7 and the fixing member 6. The first ventilation groove 19 can be provided on the outer side wall of the valve core body 71, or on the outer surface of the assembly of the fixing member 6 and the valve core 7. The gas discharged from the gas assembly 4 moves to the outside of the valve body assembly through the first ventilation groove 19, and the direction of the arrow indicates the direction of movement of the gas.

[0100] Furthermore, the fixing member 6 abuts against the side wall of the housing 1 close to the air leakage end 5 ; a sealing member 11 is further provided between the fixing member 6 and the housing 1 ; the sealing member 11 is provided around the air leakage end 5 .

[0101] In some embodiments, a seal 11 is provided to prevent gas in the gas component 4 from leaking from the gap between the fixing member 6 and the housing 1 when the valve body assembly is in the second position, thereby preventing the gas component 4 from being filled.

[0102] Furthermore, the outer cover of the valve core 7 is provided with a silencer 12, which is configured to reduce the noise generated during exhaust. In some embodiments, the silencer 12 can reduce the noise generated by gas vibration during exhaust and improve the quietness of the overall structure.

[0103] 14-15 , the housing 1 is further provided with an exhaust hole 13 , which connects the first space with the outside air. In some embodiments, the gas in the gas assembly 4 is discharged into the first space and then moves to the outside through the exhaust hole 13 .

[0104] A silencer 12 is also provided at the exhaust hole 13, which can reduce the noise generated by the movement of gas at the exhaust hole 13. The arrow direction in Figure 15 represents the direction of gas movement.

[0105] In some embodiments, the exhaust hole 13 may also be provided at a position close to the exhaust end 5 in Figure 2. In Figures 2 and 5, N and S represent magnetic poles, respectively.

[0106] In FIG5 , the air release end 5 is arranged along the first direction, and the transmission member 2 rotates with the parallelism of the first direction as the axis under the drive of the driving device 8. The permanent magnet 3 arranged on the transmission member 2 rotates accordingly, and sequentially attracts the valve core 7 to move, switching the state of the valve body assembly.

[0107] In Figures 6 and 7 , the fixing member 6 is provided with an air outlet 23, which is configured to discharge gas entering the first vent groove 19 through the valve body assembly into the first space. In some embodiments, the arrangement of the air release port 5 is shown in Figure 8 . When installation space is limited, this arrangement can be used in conjunction with the structure in Figure 5 to save space.

[0108] Figures 9, 10, and 13 show different arrangements of the permanent magnets 3 and the counterweights 17. The number of vacancies on the transmission member 2 varies, and there are many different arrangements. Figures 9, 10, and 13 are used as examples.

[0109] Figures 16-19 are top views of the first, second, third, and fourth embodiments of the permanent magnet. The shape of the permanent magnet 3 can be adjusted based on the actual effect of adsorbing the valve core 7. Furthermore, the length of the permanent magnet 3 along the direction of movement within the first space is 2-12 mm.

[0110] The effective length setting can ensure that the valve core 7 maintains the deflated state for a certain period of time. Within the unit time, a certain amount of gas can be discharged, and the hardness of the gas component 4 has a certain change; this cycle ensures an effective vibration feeling.

[0111] The present disclosure provides a car seat massage system, including the staggered car seat massage pulsation generator of the above-mentioned embodiment; also including: an air-using component 4, which is connected to the air discharge end 5 of the magnetic valve type car seat massage pulsation generator through a pipeline 21 and maintains airtightness; a controller 20, which is respectively connected to the air-using component 4 and the air source component through the pipeline 21, and is configured to control the inflation and deflation of the air-using component 4; an air source component, which is interconnected with the air-using component 4 through the pipeline 21; the air source component is configured to inflate the air-using component 4 through the pipeline 21 via the controller 20.

[0112] Specifically, referring to Figure 11 , the air source assembly 14 continuously inflates the air-consuming assembly 4. The air enters the air-consuming assembly 4 through the air valve 15 within the controller 20, and the other end of the air-consuming assembly 4 is connected to the air release port 5. When the valve core 7 is in the first position, the air in the air-consuming assembly 4 is discharged at a rate greater than the inflation rate, causing the air pressure in the air-consuming assembly 4 to decrease and relax. When the valve core 7 is in the second position, the air in the air-consuming assembly 4 is no longer discharged. Due to the inflation effect of the air source assembly 14, the air pressure continues to increase, causing the air-consuming assembly 4 to tighten.

[0113] In FIG11 , the direction of the arc arrow is the rotation direction of the transmission member 2 , and the straight arrow indicates the gas flow direction.

[0114] Repeatedly switching the valve assembly between the first and second positions repeatedly adjusts the air pressure within the air assembly 4. When a person leans against the massager, they can feel the air assembly 4 repeatedly tightening and relaxing. This repeated tightening and relaxing of the air assembly 4 creates a vibrating massage effect. Multiple air valves 15 form a controller 20, each connected to the air assembly 4, to control the inflation and deflation of the air assembly 4.

[0115] Specifically, the gas-using component 4 is an air bag, and one or more can be designed as needed. A controller 20 is provided, each equipped with at least one air valve 15, corresponding one to each air bag. The gas source component is an air pump 14. The air source component continuously blows gas into a pipeline 21, which then enters the controller 20. When the inflation air path controlled by the air valve 15 is opened, the corresponding air bag is inflated.

[0116] Figure 23 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 magnetic valve-type car seat massage pulsator causes air pressure fluctuations, which in turn causes the bag to vibrate. The waveform indicates that during inflation, the magnetic valve-type car seat massage pulsator can cause repeated fluctuations in airbag pressure.

[0117] 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

[0118] The magnetic valve-type car seat massage pulsation generator and massage system disclosed herein utilizes a permanent magnet to attract a valve assembly, controlling its opening and allowing gas to be discharged through the deflated end. Rapid circular motion of the permanent magnet within a first space allows the valve assembly to rapidly switch states. During inflation of the gas assembly, a regular, low-flow deflation of air occurs, causing the gas assembly to vibrate due to changes in volume and softness.
