Description

Technical Field

[0001] This disclosure relates to the field of automotive parts technology, specifically to a pulse massage generator and a pulse massage pneumatic system for automotive seats. Background Technology

[0002] Existing car seats either lack vibration massage function or have only a few that do. The method involves filling an air bag with air and then relying on the rotation of a motor to make the air bag vibrate, thereby achieving a massage effect. This method has high motor costs and presents problems such as installation difficulties.

[0003] Another existing massage function works by inflating and deflating an air bag, relying on the change in the volume of gas inside the bag to achieve a massage effect. This method has a low vibration frequency and poor massage effect.

[0004] Therefore, we propose a pulse massage generator. Summary of the Invention

[0038] The first pneumatic structure includes a first torsion shaft 14. The drive end near the first housing extends movably into the interior of the first housing and is coaxially fixedly connected to the first torsion shaft 14. A first rotating hole is provided on the side wall of the first torsion shaft 14 away from the drive member 1. The first rotating hole is not coaxial with the drive end. Optionally, a first preset angle is formed between the axis of the first rotating hole and the first direction, and its opening direction is towards the axis of the drive end.

[0039] Furthermore, the first pneumatic structure also includes a first swing plate 15. A first rotating shaft is provided on the side wall of the first swing plate 15 near the drive member 1. Optionally, the first rotating shaft is located at the center of the side wall of the first swing plate 15 near the drive member 1. The first rotating shaft is movably disposed in the first rotating hole. At least one first actuator 16 is provided on the side wall of the first swing plate 15 away from the drive member 1. A first space is formed inside the first actuator 16. Taking the figure as an example, the number of first actuators 16 is four.

[0040] Furthermore, four first air holes 17 are provided on the first bottom cover 5 corresponding to the four first actuators 16. The first air holes 17 are opened through the first bottom cover 5 and are connected to the first space.

[0041] Furthermore, the first top cover 6 is provided with four first air nozzles 7 corresponding to the four first actuators 16, and the four first air nozzles 7 and the four first air holes 17 are in one-to-one correspondence and connected; the first top cover 6 is provided with four partition walls 37 corresponding to the four first air nozzles 7 to improve the sealing performance.

[0042] Furthermore, the first bottom cover 5 is also provided with a positioning post 18 and a first anti-misalignment part 22. Correspondingly, the first top cover 6 is provided with a second positioning hole 39 and a third anti-misalignment part, which are used to cooperate with the positioning post 18 and the first anti-misalignment part 22, respectively. Optionally, the positioning post 18 and the first anti-misalignment part 22 extend into the second positioning hole 39 and the third anti-misalignment part, respectively. Optionally, the first anti-misalignment part 22 is a trapezoidal structure. The positioning post 18, the first anti-misalignment part 22, the second positioning hole 39, and the third anti-misalignment part are used to prevent misassembly when assembling the first pneumatic structure.

[0043] Furthermore, a first rubber pad 19 is provided between the first bottom cover 5 and the first top cover 6. The first rubber pad 19 is provided with a first positioning hole 21 and a second anti-misalignment part 23 corresponding to the positioning post 18 and the first anti-misalignment part 22, so that the positioning post 18 and the first anti-misalignment part 22 can pass through. The first rubber pad 19 is provided with a second air hole 20 corresponding to the first air hole 17. The first rubber pad 19 is used to seal the gap between the first bottom cover 5 and the partition wall 37, so that the multiple first air passages are not interconnected.

[0044] The second pneumatic structure includes a second torsion shaft 24, with the drive end near the second housing extending movably into the interior of the second housing and being coaxially fixedly connected to the second torsion shaft 24. A second rotating hole is provided on the side wall of the second torsion shaft 24 away from the drive member 1. The second rotating hole and the drive end are not coaxial. Optionally, a second preset angle is formed between the axis of the second rotating hole and the first direction, and its opening direction is the axis of the drive end.

[0045] Furthermore, the second pneumatic structure also includes a second swing plate 25. A second rotating shaft is provided on the side wall of the second swing plate 25 near the drive member 1. Optionally, the second rotating shaft is located at the center of the side wall of the second swing plate 25 near the drive member 1. The second rotating shaft is movably disposed in the second rotating hole. Four second actuators 38 are provided on the side wall of the second swing plate 25 away from the drive member 1. A second space is formed inside the second actuators 38.

[0046] Furthermore, the second bottom cover 11 is provided with four third air holes corresponding to the four second actuators 38, and a first limiting part 26 is provided in the third air hole. The third air hole is connected to the second space. The second bottom cover 11 is also provided with four fourth air holes corresponding to the four second actuators 38. A second one-way valve 27 is provided in the fourth air hole. The fourth air hole is connected to the second space.

[0047] Furthermore, the second top cover 12 has a third space, which is connected to the third air hole. The second top cover 12 also has a fourth space, which is isolated from the third space and is connected to the fourth air hole. A second air nozzle 13 is provided on the side wall of the second top cover 12 away from the driving member 1, and the second air nozzle 13 is connected to the fourth space.

[0048] Furthermore, there is a gap between the second outer shell and the drive component 1, and the gap is connected to the interior of the second outer shell. The second bottom cover 11 is provided with four seventh air holes 31, one end of the seventh air hole 31 is connected to the interior of the second outer shell, and the other end is connected to the third space.

[0049] Furthermore, a second rubber pad 28 is provided between the second bottom cover 11 and the second top cover 12. A fifth air hole 29 is provided on the second rubber pad 28 corresponding to the third air hole. A swing plate is provided inside the fifth air hole 29. A second limiting part 40 is provided inside the second bottom cover 11 corresponding to the fifth air hole 29. Thus, the swing plate is located between the first limiting part 26 and the second limiting part 40, forming a first one-way valve. Due to the limiting of the first limiting part 26 and the second limiting part 40, the swing plate can only swing in the direction of the second actuating member 38, allowing gas to enter the actuating member 38, but cannot swing in the direction of the second top cover 12.

[0050] Furthermore, a sixth vent 30 is provided on the second rubber pad 28 corresponding to the fourth vent, and an eighth vent 32 is provided on the second rubber pad 28 corresponding to the seventh vent 31; the second rubber pad 28 is used to seal the gap between the third space and the fourth space, so that the third space and the fourth space are not connected to each other.

[0051] By activating the drive unit 1, both drive ends are driven to rotate simultaneously, thereby enabling both the first and second pneumatic structures to start working. The drive end closer to the first outer shell rotates, causing the first torsion shaft 14 to rotate. Since the first rotating hole and the drive end are not on the same axis, the first rotating hole performs a circular motion, causing the first rotating shaft to twist, thereby causing the first swing plate 15 to twist. The first swing plate 15 repeatedly and sequentially squeezes the four first actuators 16. The four first actuators 16 deform and recover sequentially, thereby causing the four second spaces to deform and recover sequentially.

[0052] When the first actuator 16 is squeezed by the first swing plate 15, the first space deforms and squeezes out air, and the air is output from the first air nozzle 7;

[0053] When the first actuator 16 is restored, the first space is restored, so that air can be drawn in from the first air nozzle 7;

[0054] The drive end near the second outer shell rotates, causing the second torsion shaft 24 to rotate. Since the second rotating hole and the drive end are not on the same axis, the second rotating hole makes a circular motion, causing the second rotating shaft to twist, thereby causing the second swing plate 25 to twist. The second swing plate 25 repeatedly squeezes the four second actuators 38 in sequence. The four second actuators 38 deform and recover in sequence, thereby causing the four second spaces to deform and recover in sequence.

[0055] When the second actuator 38 is squeezed by the first swing plate 15, air is squeezed out of the second space, and the air is output from the second air nozzle 13 through the second one-way valve 27.

[0056] When the second actuator 38 is restored, the second space is restored, thereby reducing the pressure inside the second housing. Outside air enters the second housing through the gap, and then enters the third space, passing through the first one-way valve into the second space.

[0057] Optionally, an air inlet or air nozzle is provided on the second housing. When the second actuator 38 is restored, the second space is restored, thereby reducing the pressure inside the second housing. Outside air enters the second housing through the air inlet or air nozzle, and then enters the third space, passing through the first one-way valve into the second space.

[0058] like Figure 6 As shown, the first air nozzle 7 is connected to the first air tube 8, and the end of the first air tube 8 away from the first air nozzle 7 is connected to the massage bag 2. Thus, through the continuous deformation and recovery of the first actuating member 16, the air moves back and forth in the first air tube 8, causing the massage bag to continuously expand and contract, forming an impact and realizing a pulsating massage on the human body; the first space, the first air hole 17, the second air hole 20 and the interior of the first air nozzle 7 form the first air passage.

[0059] Furthermore, it also includes a control air circuit assembly, which includes a control module 33, a second air tube 34, and at least one third air tube 35. As shown in the figure, there are four third air tubes 35. The control module 33 has an input end and at least one output end. Correspondingly, there are four output ends. The input end is connected to the second air tube 34 and the second air nozzle 13, and the output end is connected to the massage bag 2 through the third air tube 35. The control module 33 is provided with a switch valve.

[0060] Furthermore, the air nozzle of the switching valve forms the output end, and the switching valve can be a three-way valve; the control module 33 consists of a circuit board and a switching valve. The circuit board can control the start and stop of the drive component 1 and whether the switching valve is energized, thereby controlling whether to inflate a certain massage bladder 2.

[0061] Working principle: When a massage bag 2 needs to work, the rotation of the two drive ends drives the first pneumatic structure and the second pneumatic structure to work respectively. Through the switch valve, when the second pneumatic structure is working, air can be selectively injected into a massage bag 2, making the massage bag 2 work. The first pneumatic structure causes the air to move back and forth in the first air passage corresponding to the massage bag 2, forming an impact. When the massage bag 2 is not working, the air in the massage bag 2 is output to the outside through the switch valve, and the massage bag 2 is deflated.

[0062] Depending on the user's specific needs, massage bladders can be placed in the lumbar region, back, neck, or any other location requiring massage function on a car seat (or other seats). The control module 33 controls the drive unit 1 to inflate the massage bladder 2. Simultaneously, the first pneumatic structure causes the massage bladder 2 to impact, vibrating at a certain frequency to achieve a pulsating massage effect. After the control module controls the massage bladder 2 to vibrate and massage for 3-5 seconds, the pressure is released through a second channel, and then the system switches to the next massage bladder 2 for inflation and massage. This cycle repeats continuously, achieving a cyclical massage effect on the lumbar region, back, and neck.

[0063] It should be noted that the specific massage frequency can be adjusted by changing the control module program settings according to user needs.

[0064] It should be noted that the four massage bladders 2 work in a cyclical alternation. The massage bladders 2 work and stop at times. As long as one massage bladder 2 is working, the drive unit 1 will work continuously. The other massage bladders 2 that are not working will also have an air intake and exhaust action. The air flow is continuous, so the massage bladders 2 that are not working can play a role in heat dissipation for the control module.

[0065] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
