It is to be explained that the features in the embodiments of this disclosure can be combined with each other without contradiction.As mentioned in the Technical Background section, as people improve their life standard, there are ever-increasing demands placed on the driving experience when driving with a vehicle. In order to enable a massage operation to be experienced when driving with a vehicle, vehicle seats are equipped with a massage device by research personnel in the automobile industry, and a vibration function is also added to these to meet the requirements.The working process of existing vibration massagers for vehicle seats is as follows: an air pump is in communication with an air bag via an air supply line and inflates the air bag, and a vibration motor is provided between the air pump and each air bag, respectively. When a vibration function is turned on, the vibration motor will vibrate at different vibration frequencies depending on the selected massage mode, which is transmitted to a human body via the air bag, thereby realizing a massage effect. The manner of realizing vibration by the vibration motor is influenced by the inherent characteristics of the vibration motor itself. The vibration frequency of the vibration motor is generally above 100 Hz. Compared with the vibration frequency of 8-15 Hz comfortable to a human body, the vibration is too fast and the comfort is poor. In addition, each airbag is assigned a vibration motor, and a comparatively large space in the vehicle seat is occupied, which makes control difficult.In view of this, this problem can be solved by a solenoid-valve type vehicle seat massage pulsation generator and a massage system provided in the embodiments of this disclosure, and above that, a detailed description will be made below.The core concept of the present disclosure is as follows: The operation for controlling the inflation of the air consumption assembly is improved, a mode for continuously inflating the air consumption assembly and regulating an inflation frequency is adopted, and a vibration effect is finally realized by vibrating the air consumption assembly.The operating principle of this disclosure is as follows: An air source assembly communicates with an air consumption assembly, while the other end of the air consumption assembly communicates through an air discharge end with the housing of a pulsation generator. Disposed within the housing are a valve body assembly configured to control air venting of the air consumption assembly and a permanent magnet configured to control opening of the valve body assembly. The permanent magnet is fixed to the driving side of a driving assembly via a power transmission member and is configured to rotate under driving of the driving assembly. By the rapidly rotatable drive assembly, the permanent magnet disposed on the power transmission member is controlled to rotate rapidly.When the permanent magnet moves toward the valve cartridge, the permanent magnet attracts the ferromagnetic valve cartridge, thereby being opened to inflate the air bag; and when the permanent magnet moves away from the valve cartridge, the valve cartridge is restored by an elastic member. By the driving assembly rotating rapidly, the valve cartridge can be repeatedly opened and closed, so that periodic inflation of the air bag during inflation is realized to produce a vibration effect.A reference formula (I) which is a formula for calculating an attractive force between a magnetic field generating source and an attracted object. wherein F represents the attractive force, K represents a constant and is obtained by measurements according to actual experimental scenarios, m represents the magnetic moment of the magnetic field generating source, and d represents the distance between the magnetic field generating source and the attracted object.Referring to FIGS. 1, 2, and 3, a solenoid-valve-type vehicle seat massage pulsation generator provided in the present disclosure includes:a housing 1, wherein a first space is provided inside the housing, and at least one air discharge end 5 is fixed to the housing 1; wherein the air discharge end 5 is configured for communication between an air consumption assembly 4 and the first space; a valve body assembly, wherein at least one valve body assembly is provided, and the valve body assemblies are all disposed in the first space and are in one-to-one relationship with the air discharge ends 5; wherein the valve body assembly comprises a valve insert 7 adjacent to the air discharge end 5 and made of a soft magnetic material; and a permanent magnet 3, wherein at least one permanent magnet 3 is provided and mounted in the housing 1; wherein the permanent magnet 3 is movable in the first space; wherein the valve insert 7 has a first position and a second position; In the first position of the valve insert 7, the permanent magnet 3 moves toward the valve insert 7 and attracts the valve insert 7, the valve insert 7 is driven to separate from the air discharge end 5, and the valve body assembly is opened and is configured such that air is discharged from the air consumption assembly 4 through the air discharge end 5; and in the second position of the valve insert 7, the permanent magnet 3 moves away from the valve insert 7, the valve insert 7 is reset, and the valve body assembly is closed and is configured to prevent the discharge of the air from the air consumption assembly 4 through the air discharge end 5.In this embodiment, by using the permanent magnet 3 to adsorb the valve insert 7, the valve body assembly is controlled to be opened so that air is discharged through the air discharge end 5. The effect of controlling the valve body assembly for rapid state switching is enabled by controlling the permanent magnet 3 to rapidly orbit in the first space; and during an inflation operation of the air consumption assembly 4, air is regularly released at a small flow rate, so that the air consumption assembly 4 undergoes a change in softness or hardness due to the change in the air volume in the air consumption assembly 4, thereby realizing a vibration effect.Specifically, the soft magnetic material is specifically iron, cobalt, or nickel, or an iron-containing, cobalt-containing, or nickel-containing alloy.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 discharge ends 5, and the upper housing and the lower housing are detachably connected to each other. A plurality of mounting holes are provided on the upper housing for fastening the upper housing and the lower housing by means of a screw connection.Further, it further comprises: a power transmission assembly disposed in the first space, wherein the permanent magnet 3 is fixedly attached to the power transmission assembly, and the power transmission assembly is configured to drive the permanent magnet 3 to rotate, thereby controlling the valve plug 7 to switch between the first position and the second position; and a driving device 8 fixedly attached to the housing 1, wherein the driving side of the driving device 8 passes through the housing 1 and is fixedly connected to the power transmission assembly, and is configured to drive the power transmission assembly to rotate, thereby controlling, by the power transmission assembly, the valve plug 7 to switch between the first position and the second position.Further, the power transmission assembly includes a power transmission member 2, wherein referring to what is shown in FIGS. 9 and 12, the power transmission member 2 is disk-shaped and is firmly connected to the driving side of the driving device 8; and the permanent magnet 3 is completely embedded in the power transmission member 2, or is partially exposedly attached to an outer side wall of the power transmission member 2 that is perpendicular to the rotational axis, and the power transmission member 2 drives the permanent magnet 3 to rotate so as to move toward or away from the valve plug 7.In some embodiments, referring to what is shown in FIG. 5, the power transmission member 2 is cylindrical and is fixedly connected to the driving side of the driving device 8; and the power transmission member 2 rotates under driving of the driving device 8, the permanent magnet 3 is disposed on an outer side wall of the power transmission member 2 that is parallel to the rotation axis, and the power transmission member 2 drives the permanent magnet 3 to rotate so as to move toward or away from the valve plug 7. Specifically, the driving device 8 is a motor.Specifically, during the turning operation with the force transmission member 2, the permanent magnet 3 will move to a position close to or just aligned with the valve body assembly, and the valve insert 7 made of a soft magnetic material will move toward the permanent magnet 3 under the action of the magnetic field of the permanent magnet 3. At this time, the valve plug 7 is in the first position and maintains the open state, the valve body assembly is no longer adjacent to the air discharge end 5, and air from the air consumption assembly 4 is discharged through the air discharge end 5.In some embodiments, the direction of the rotation axis of the power transmission member 2 is parallel to the opening direction of the air discharge end 5. the power transmission member 2 is disk-shaped, and the permanent magnet 3 is completely embedded in the power transmission member 2, or is partially exposedly attached to an outer side wall of the power transmission member 2 that is perpendicular to the rotation axis of the power transmission member 2. The power transmission member 2 rotates under the driving of the driving device 8, and then drives the permanent magnet 3 to rotate. When the permanent magnet 3 is close to or just aligned with the valve core 7, the valve body assembly is adsorbed to be opened and switched to the first position; and when the permanent magnet 3 is removed from the valve body assembly, the closed state of the valve body assembly is maintained and the valve body assembly is switched to the second position.Specifically, the permanent magnet 3 may be completely embedded in the force transmission member 2, i.e., the permanent magnet 3 is invisible from the outside of the force transmission member 2. The permanent magnet 3 could also be arranged partly exposed on a surface of the force transmission element 2, i.e. a surface of the permanent magnet 3 is visible from the outside of the force transmission element 2.Further, the power transmission member 2 is cylindrical, the permanent magnet 3 is dispersed on an outer side wall of the power transmission member 2, and during the rotating operation of the power transmission member 2, the rotating trajectory of the permanent magnet 3 passes through the position of the valve plug 7.In some embodiments, the direction of the rotation axis of the power transmission member 2 is perpendicular to the opening direction of the air discharge end 5. the power transmission member 2 is cylindrical, and the permanent magnet 3 is dispersed on a side wall of the power transmission member 2 that is parallel to the rotation axis of the power transmission member 2. The specific case is shown in FIG. 5. The rotational direction thereof is perpendicular to the moving direction of the valve plug 7. During the rotating operation, the cylindrical force transmission member 2 drives the permanent magnet 3 to move to switch the valve plug 7 between the first position and the second position.Further, referring to FIGS. 9, 10, and 12, the power transmission member 2 is still provided with at least one counterweight 17, and the balances 17 and the permanent magnets 3 are arranged uniformly along the circumferential direction of the power transmission member 2. In some embodiments, a plurality of permanent magnets 3 and a plurality of counter weights 17 are randomly arranged along the circumferential direction of the power transmission member 2, which, when the permanent magnets 3 are rotated with the power transmission member 2, controls the period of time in which the valve body assembly is adsorbed by the permanent magnets 3 using the characteristic of different distances between the permanent magnets 3. Finally, it is realized that the air discharging operation of the air consumption assembly 4 is controlled at different intervals.By regulating the distances between the permanent magnets 3, it can be realized that the discharge of the air consumption assembly 4 is controlled with different frequencies, and finally an effect of vibration massage with different frequencies is realized.In order to prevent instability of the power transmission member 2 due to centrifugal action in rotation, a counter weight 17 is additionally provided so that the power transmission member 2 is more stable in rotation.Further, referring to FIGS. 1, 2, 6, and 7, the valve body assembly includes a fixing member 6 fixedly mounted in the first space; and the valve plug 7 is mounted on the fixing member 6 and is movable relative to the fixing member 6.Specifically, the fixing member 6 is provided with a positioning column 22 configured to be preliminarily fixed to a positioning hole 18 on the housing 1 upon attachment, which ensures a precise attachment position.Further, as shown in FIGS. 4 and 20, the valve plug 7 includes a valve plug body 71 and a first boss 72 provided on a side of the valve plug body 71 opposite to the air discharge end 5; when the valve plug 7 is in the first position, an end of the first boss 72 opposite to the air discharge end 5 protrudes from the fixing member 6; and when the valve plug 7 is in the second position, the end of the first boss 72 opposite to the air discharge end 5 protrudes from the fixing member 6 or is flush with an end of the fixing member 6 opposite to the air discharge end 5.Specifically, the valve insert 7 is movable along a direction parallel to the air discharge end 5.When the valve insert 7 and the air discharge end 5 are separated from each other, the valve body assembly is in the first position. When the valve insert 7 is adjacent the air discharge end 5, the valve body assembly is in the second position. By regulating the state of the valve insert 7, the air consumption assembly 4 can be controlled to be switched between an inflation state and an exhaust state. By repeatedly regulating the state of the valve plug 7, a repeated tension and relaxation operation of the air consumption assembly 4 can be realized.Further, the valve body assembly further comprises an elastic member 10, wherein one end of the elastic member 10 abuts a connection point between the valve plug body 71 and the first boss 72, while the other end abuts the fastening member 6, and the elastic member is configured to drive the valve plug 7 to move to the second position when the valve plug 7 is removed from the air discharge end 5 and the permanent magnet 3 is removed from the valve plug 7. In some embodiments, the elastic member 10 is a spring. The valve insert 7 is made of a soft magnetic material.By providing the elastic member 10, it is possible that the valve cartridge 7 can be automatically restored to the state of abutting the air discharge end 5 when the permanent magnet 3 is removed from the valve cartridge 7, thereby preventing the discharge of the air from the air consumption assembly 4.The magnetic force applied from the permanent magnet 3 to the valve body assembly is greater than the maximum spring force of the elastic member 10. Therefore, when the permanent magnet 3 moves toward the valve body assembly, the valve plug 7 can overcome the spring force of the elastic member 10 under the action of the magnetic force and then move away from the air discharge end 5, thereby discharging the air from the air consumption assembly 4 through the air discharge end 5.In some embodiments, an end of the valve insert 7 facing the air discharge end 5 is provided with an abutment member 9 configured to abut the air discharge end 5, thereby securing the tightness of the air discharge end 5. Specifically, rubber or silica gel is used for the abutment member 9 to ensure the tightness when the abutment member 9 abuts the air discharge end 5.When the valve body assembly is in the second position, the abutment member 9 abuts the air discharge end 5 and the tightness is maintained to realize the air discharge preventing effect. By using an abrasion resistant material, the life of the valve body assembly can be extended because during the working process it is necessary to continuously and repeatedly control the abutment member 9 to abut or separate from the air discharge end 5.Further, the valve body assembly is further provided with a first ventilation slit 19; the first ventilation slit 19 is provided on the fixing member 6 or the valve insert body 71; and the first ventilation slit 19 is configured to guide the air discharged from the air discharge end 5 from the first ventilation slit 19 into the first space.Specifically, as shown in FIGS. 1, 2, 21, and 22, a first ventilation slit 19 is provided between the valve insert 7 and the fastening member 6. The first ventilation slit 19 may be disposed on an outer side wall of the valve plug body 71 or disposed on an outer surface of the fixing member 6 assembled with the valve plug 7. The air discharged from the air consumption assembly 4 moves to the outside of the valve body assembly through the first ventilation slit 19, and the arrow direction represents the moving direction of the air.Furthermore, the fastening element 6 adjoins the side wall of a side of the housing 1 facing the air discharge end 5; a sealing element 11 is also arranged between the fastening element 6 and the housing 1; and the sealing element 11 is arranged around the air discharge end 5.In some embodiments, the provision of the sealing member 11 may ensure that, in the second position of the valve body assembly, leakage of air in the air consumption assembly 4 through a gap between the fastening member 6 and the housing 1 is prevented, resulting in the air consumption assembly 4 being difficult to fully inflate.Furthermore, on the outside of the valve insert 7, a sound attenuation element 12 is provided so as to be enveloping, which is configured to reduce the noise generated during the air discharge. In some embodiments, providing the sound attenuation member 12 may reduce the noise generated in the air exhaust due to the air vibration and improve the noiseless performance of the overall structure.Further, referring to FIGS. 14 to 15, the housing 1 is also provided with a vent hole 13 that allows communication between the first space and the outside air. In some embodiments, after being discharged into the first space, the air moves out of the air consumption assembly 4 through the vent hole 13.A sound absorbing member 12 is disposed at the vent hole 13, and thus the noise generated by the air movement at the vent hole 13 can be reduced. The arrow direction in FIG. 15 represents the moving direction of the air.In some embodiments, the vent hole 13 may be disposed at a position facing the air discharge end 5 in FIG. 2. In FIGS. 2 and 5, N and S represent the magnetic poles, respectively.In FIG. 5, the air discharge ends 5 are distributed along a first direction, the power transmission member 2 rotates about an axis parallel to the first direction under driving of the driving device 8, and the permanent magnets 3 arranged on the power transmission member 2 rotate therewith and successively attract the valve plug 7 to move, thereby switching the state of the valve body assembly.In FIGS. 6 and 7, the fixing member 6 is provided with an air outlet 23 configured to discharge the air entering the first ventilation slit 19 into the first space via the valve body assembly. In some embodiments, the distribution of air discharge ends 5 is shown in FIG. 8, and if the installation space is not sufficient, this mode may be combined with the structure in FIG. 5 for use to save space.FIGS. 9, 10, and 13 respectively show different distribution modes of the permanent magnets 3 and the balances 17. the numbers of voids on the power transmission member 2 are different, and there are also a plurality of distribution modes. Here, FIGS. 9, 10, and 13 are cited as an example.FIGS. 16 to 19 show the plan views of the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment of the permanent magnet, and the shape of the permanent magnet 3 can be regulated according to the actual effect of the adsorption of the valve plug 7. Further, the permanent magnet 3 has a length of 2-12 mm along the moving direction in the first space.Effective length adjustment can ensure that the valve plug 7 maintains the discharged state for a certain period of time, discharge of a certain amount of air can be ensured during a unit time, and the softness of the air consumption assembly 4 changes, and such a cycle ensures effective vibration feeling.The present disclosure provides a massage system for vehicle seats, comprising a vehicle seat massage pulsation generator of an offset motion type according to the above embodiments; further comprising: an air consumption assembly 4 that communicates with the air discharge end 5 of the solenoid-operated vehicle seat massage pulsation generator via a piping 21 and maintains airtightness; a controller 20 that communicates with the air consumption assembly 4 and an air source assembly via a piping 21, respectively, and is configured to control inflation and deflation of the air consumption assembly 4; and an air source assembly, wherein the air source assembly and the air consumption assembly 4 communicate with each other via the piping 21; wherein the air source assembly is configured to inflate the air consumption assembly 4 by the controller 20 via the piping 21.Specifically, referring to FIG. 11, the air consumption assembly 4 is continuously inflated by the air source assembly 14, and air enters the air consumption assembly 4 through an air valve 15 in the controller 20 while the other end of the air consumption assembly 4 is in communication with the air discharge end 5. When the valve cartridge 7 is in the first position, the air discharge speed from the air consumption assembly 4 is greater than the inflation speed, therefore the air pressure in the air consumption assembly 4 is decreased and the air consumption assembly 4 is relaxed. When the valve cartridge 7 is in the second position, air is no longer exhausted from the air consumption assembly 4, and due to the inflating action of the air source assembly 14, the air pressure is continuously increased and the air consumption assembly 4 is tensioned.The direction of the arc-shaped arrow in FIG. 11 represents the rotational direction of the power transmission member 2, and the straight arrow represents the flow direction of the air.The air pressure in the air consumption assembly 4 can be regulated repeatedly by switching the valve body assembly between the first position and the second position repeatedly. When engaged with the massager, a human body can sense the action of repeated tension and relaxation of the air consumption assembly 4. The air consumption assembly 4 is repeatedly tensioned and relaxed to realize the effect of vibration massage. A plurality of air valves 15 constitute the controller 20 and are respectively communicated with the air consumption assembly 4, thereby controlling the blowing-up and blowing-out operation of the air consumption assembly 4.Specifically, the air consumption assembly 4 is an air bag, and one or more air bags may be formed and provided as needed; a group of controllers 20 is provided, and at least one air valve 15 is provided inside the controller 20, and the air valves 15 are in one-to-one relationship with the air bags; and the air source assembly is an air pump 14. The air source assembly blows air continuously into the duct 21, and air enters the controller 20 via the duct 21.FIG. 23 illustrates an oscillogram of air pressure in the air bag during the working process, wherein the horizontal axis t(s) represents time in second and the vertical axis P(kpa) represents air pressure in the air bag in KPa. During inflation of the air bag by the air source assembly, the air pressure inside the air bag is directly related to the change in the hardness of the air bag caused by the deformation of the air bag. The higher the air pressure in the air bag, the higher the hardness of the air bag; the lower the air pressure, the lower the hardness. The periodic release of air of the solenoid-valve type vehicle seat massage pulsation generator causes the air pressure to fluctuate, so that the hardness of the air bag changes, whereby the air bag generates a vibration effect. According to the waveform, it can be determined that during the inflation operation, the operation of the solenoid-type vehicle seat massage pulsation generator can realize repeated variation of the air pressure in the air bag.The above description merely illustrates preferred embodiments of this disclosure and the technical principles used. It should be understood by those skilled in the art that the inventive scope affected in this disclosure is not limited to technical solutions formed by specific combinations of the above technical features, but should include still other technical solutions formed by arbitrary combinations of the above technical features or their equivalents without departing from the inventive concept, for example, technical solutions formed by substituting the above features with technical features disclosed (but not limited to) in this disclosure having similar functions or reverse substitution.Industrial applicabilityIn the solenoid-valve type vehicle seat massage pulsation generator and the massage system provided in this disclosure, by using the permanent magnet to adsorb the valve body assembly, the valve body assembly is controlled to be opened so that air is discharged through the air discharge end. The effect of controlling the valve body assembly for rapid state switching is enabled by controlling the permanent magnet to rapidly orbit in the first space; and during an inflation operation of the air consumption assembly, air is regularly released at a small flow rate, so that the air consumption assembly undergoes a change in softness or hardness due to the change in the air volume in the air consumption assembly, thereby realizing a vibration effect.List of reference numbers:1 Housing; 2 Force transmission member; 3 Permanent magnet; 4 Air consumption assembly; 5 Air discharge end; 6 Fixing member; 7 Valve insert; 8 Driving device; 9 Abutting member; 10 Elastic member; 11 Sealing member; 12 Sound attenuation member; 13 Vent hole; 14 Air source assembly; 15 Air valve; 16 Solenoid-valve-type vehicle seat massage pulsation generator; 17 Counterweight; 18 Positioning hole; 19 First ventilation slit; 20 Controller; 21 Piping; 22 Positioning column; 23 Air outlet. 71 valve insert body; 72 first bossReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
