Abstract
Description
Technical Field
[0001] This application relates to the field of pneumatic noise reduction technology, and in particular to a seat pneumatic system with a noise reduction structure. Background Technology
[0002] With the continuous development of technology in the field of vehicle transportation, people have higher and higher requirements for vehicle riding comfort. As a result, seat massage devices have emerged, effectively solving the problem of fatigue during long-term driving.
[0003] Most of the massage devices that come with vehicles on the market today use a pneumatic structure. The pneumatic structure uses an air pump as a power source to blow air through a control valve into the support airbag located at the back of the foam pad. By inflating and deflating the support airbag, the seat surface can be partially raised or flattened, thereby achieving a support and massage effect on the human body.
[0004] However, when air is blown into the top support airbag, the rapidly ejected air will produce a loud airflow sound, and these impacts and noises will affect the comfort of the massage. Utility Model Content
[0005] In order to solve some or all of the above-mentioned technical problems, this application provides a seat pneumatic system with a noise reduction structure.
[0006] This utility model provides a seat pneumatic system with a noise reduction structure. The seat pneumatic system includes: an air supply component configured as an air bag capable of massaging or supporting the occupant's body; an air supply component configured to deliver flowing gas into the air bag; a control component configured to control the flow of gas into or out of the air bag; at least one first pipe connected between the air supply component and the control component; at least one second pipe connected between the control component and the air bag, with one end of the second pipe away from the control component extending into the air bag; and a noise reduction structure disposed within the air bag, specifically installed in... At the end of the second pipeline furthest from the control component, the noise reduction structure is configured as a variable airflow dispersion section. When the air bag is inflated, the high-speed ejected airflow is delivered to the control component via the first pipeline. After being adjusted by the control component, the airflow is blown towards the variable airflow dispersion section through the second pipeline. Under the effect of airflow dispersion, the variable airflow dispersion section gradually expands, and the airflow is dispersed and blown into the air bag. When the air bag is expelled, the variable airflow dispersion section gradually becomes or has already become contracted. The airflow in the air bag will enter the second pipeline relatively slowly through the variable airflow dispersion section, be delivered back to the control component via the second pipeline, and finally be discharged from the air bag after being adjusted by the control component.
[0007] Furthermore, the variable airflow dispersion section is configured as a tubular fluid disperser, which includes N tubular flaps (N≥2) arranged around the port of the second pipeline. The N tubular flaps are allowed to move in a manner of mutual convergence or dispersion relative to the second pipeline. It should also be noted that the tubular fluid disperser is always connected to the second pipeline, whether the air bag is in an inflated or deflated state. When the air bag is inflated, the airflow, after being adjusted by the control component, is blown towards the tubular fluid disperser through the second pipeline. The N tubular flaps disperse and open under the action of the airflow, and the airflow is dispersed and blown into the air bag. When the air bag is deflating, the N tubular flaps retract and shrink, the airflow velocity decreases and enters the second pipeline relatively slowly, is transported back to the control component through the second pipeline, and after being adjusted by the control component, is finally discharged from the air bag.
[0008] Furthermore, the N tracheal valves can be configured as multi-valve tracheal bodies formed by cutting along their own diameter direction via the second conduit, that is, the N tracheal valves and the second conduit are regarded as an integrally formed structure.
[0009] Furthermore, the N tracheal valves can be configured such that each tracheal valve is movably connected to the second tubing, that is, the N tracheal valves and the second tubing are considered to be a detachable connection structure.
[0010] Furthermore, the shape of the N tracheal valves can be configured such that the cross-sectional area of the N tracheal valves remains consistent from the direction closest to the second conduit to the direction furthest from the second conduit.
[0011] Furthermore, the shape of the N tracheal valves can be configured such that the cross-sectional area of the N tracheal valves gradually decreases from the direction closest to the second conduit to the direction furthest from the second conduit.
[0012] Furthermore, the lengths of the N tracheal valves can be configured to be all equal or not all equal.
[0013] Furthermore, several ventilation holes can be added to the N tracheal valves to expand the airflow range.
[0014] As can be seen from the above technical solution, in the seat pneumatic system of this utility model, when the air bag is inflated, the high-speed jet of air is delivered to the control component through the first pipeline. After being adjusted by the control component, the airflow is blown to the variable airflow dispersion part through the second pipeline. The variable airflow dispersion part gradually expands under the action of airflow dispersion. After the airflow is dispersed by the variable airflow dispersion part, it is blown into the air bag, and the airflow velocity is reduced, thereby reducing the air explosion noise generated when the airflow blows into the air bag, achieving noise reduction, and thus bringing a better massage comfort to the occupant.
[0015] When the air bag vents air, the variable airflow dispersion section gradually becomes or has already become converging. The airflow in the air bag will enter the second pipeline relatively slowly through the variable airflow dispersion section, be transported back to the control component through the second pipeline, and finally be discharged from the air bag after being adjusted by the control component.

Detailed Implementation
[0036] The following is in conjunction with the appendix Figures 1-18This application will be described in further detail. Example 1
[0037] As mentioned in the background section, in view of the problems in the prior art, this application proposes a seat pneumatic system with a noise reduction structure, the seat pneumatic system comprising:
[0038] Air supply component 2, which is configured as an air bag 21 capable of massaging or supporting the occupant's body;
[0039] Gas supply assembly 4, which is configured to supply flowing gas into the gas bag 21;
[0040] Control component 6, which is configured to control the flow of gas into or out of the gas bag 21;
[0041] At least one first pipeline 5, which is connected between the gas supply component 4 and the control component 6;
[0042] At least one second pipe 3 is provided between the control component 6 and the air bag 21, and one end of the second pipe 3 away from the control component 6 extends into the air bag 21;
[0043] Noise reduction structure 1 is configured in the air bag 21 and is specifically installed at the end of the second pipeline 3 away from the control component 6. The noise reduction structure 1 is configured as a variable airflow dispersion section 11.
[0044] When the air bag 21 is inflated, the high-speed airflow is delivered to the control component 6 through the first pipe 5. After being adjusted by the control component 6, the airflow is blown to the variable airflow dispersion section 11 through the second pipe 3. Under the effect of airflow dispersion, the variable airflow dispersion section 11 gradually expands, and the airflow is dispersed and blown into the air bag 21. The airflow velocity is reduced, thereby reducing the air explosion sound generated when the airflow blows into the air bag 21, achieving noise reduction, and thus bringing a better massage comfort to the occupants.
[0045] When the air bag 21 exhausts air, the variable airflow dispersion section 11 gradually becomes or has already become converging. The airflow in the air bag 21 will enter the second pipeline 3 relatively slowly through the variable airflow dispersion section 11, and be transported back to the control component 6 through the second pipeline 3. After being adjusted by the control component 6, the air bag 21 is finally discharged.
[0046] In a preferred embodiment, the gas supply component 4 is preferably an air pump, which delivers flowing gas into the air bag 21; the control component 6 is preferably a controller, which has a valve body inside, and the valve body is used to regulate the gas flow state; the first pipeline 5 is connected between the air pump and the controller, and the second pipeline 3 is connected between the controller and the air bag 21.
[0047] In a preferred embodiment, the noise reduction structure 1 and the second pipeline 3 can have a one-to-one correspondence, that is, one set of the second pipeline 3 corresponds to one set of the noise reduction structure 1; alternatively, a branch pipeline can be set at the front end of the second pipeline 3, and the noise reduction structure 1 can be configured at the front end of the branch pipeline. As for the air bag 21, the second pipeline 3 and the noise reduction structure 1 can be set in any level air bag 21, or the second pipeline 3 and the noise reduction structure 1 can be set in a specified level air bag 21. The specific setting needs to be set according to the actual situation.
[0048] In a preferred embodiment, the variable airflow dispersion section 11 is configured as a tubular fluid disperser 12, which is formed by a flexible pipeline. The tubular fluid disperser 12 includes N tubular flaps 13 (N≥2) arranged around the port of the second pipeline 3. The N tubular flaps 13 form airflow gaps 19 between each other. The N tubular flaps 13 are allowed to move relative to the second pipeline 3 in a manner that allows them to converge or disperse (the accompanying drawings mainly show schematic diagrams of 4 tubular flaps 13 and 6 tubular flaps 13). The N tubular flaps 13 are completely inserted into the air bag 21 to ensure that the N tubular flaps 13 can move in the manner described above. It should also be noted that the tubular fluid disperser 12 always remains in communication with the second pipeline 3, regardless of whether the air bag 21 is in an inflated or deflated state.
[0049] When the air bag 21 is inflated, the airflow, which is adjusted by the control component 6, is blown to the air tube fluid disperser 12 through the second pipeline 3. The N air tube flaps 13 are dispersed and opened under the action of the airflow, and the airflow is dispersed and blown into the air bag 21. Since the airflow range at the port is relatively larger, the airflow velocity is weakened, which ultimately reduces the air pop noise generated when the airflow blows into the air bag 21, thereby achieving noise reduction.
[0050] When the air bag 21 vents air, the N air valves 13 retract and shrink, the airflow speed decreases and enters the second pipe 3 relatively slowly, and is transported back to the control component 6 via the second pipe 3. After being adjusted by the control component 6, the air bag 21 is finally discharged.
[0051] In a preferred embodiment, the N tracheal valves 13 can be configured as multi-valve tracheal bodies 14 formed by cutting along the diameter direction of the second conduit 3. That is, the N tracheal valves 13 and the second conduit 3 are regarded as an integrally formed structure. The advantage of this arrangement is that no additional parts need to be added. Noise reduction can be achieved by relying solely on the improvement of the second conduit 3 itself. The design concept is ingenious and the noise reduction effect is also good.
[0052] In a preferred embodiment, the N tracheal valves 13 can be configured such that each tracheal valve 13 is movably connected to the second tubing 3, that is, the N tracheal valves 13 and the second tubing 3 are considered to be a detachable connection structure. The detachable connection method includes, but is not limited to, plugging or snapping. The advantage of this arrangement is that the noise reduction structure 1 can be regarded as a separate component and installed at the end of the second tubing 3 in some way, which greatly increases the flexibility of use.
[0053] In a preferred embodiment, the shape of the N tracheal valves 13 can be configured such that the cross-sectional area of the N tracheal valves 13 remains consistent from the direction close to the second conduit 3 to the direction away from the second conduit 3, that is, the N tracheal valves 13 are arranged on the second conduit 3 with regular dimensions.
[0054] In a preferred embodiment, the shape of the N tracheal valves 13 can be configured such that the cross-sectional area of the N tracheal valves 13 gradually decreases from the direction close to the second conduit 3 to the direction away from the second conduit 3, that is, the ends of the N tracheal valves 13 are narrowed. It can also be understood that the shape of the N tracheal valves 13 can be flexibly configured, such as being rectangular, triangular or trapezoidal, but not limited to these.
[0055] In a preferred embodiment, the length of the N tracheal valves 13 can be configured such that their length is greater than 1.5 times the outer diameter of the second tube 3. The advantage of this configuration is that when the air bag 21 is inflated, the N tracheal valves 13 can have a better opening angle, a larger airflow range, and a better noise reduction effect.
[0056] In a preferred embodiment, the lengths of the N tracheal valves 13 can be configured to be all of equal length or not all of equal length, that is, the lengths of the tracheal valves 13 can be flexibly configured.
[0057] In a preferred embodiment, several ventilation holes 18 may be added to the N tracheal flaps 13 to expand the airflow range. When the air bag 21 is inflated, part of the airflow flowing through the tracheal fluid diffuser 12 can be dispersed outward along the ventilation holes 18 and blown into the air bag 21 to further reduce the air pop sound.
[0058] In a preferred embodiment, the seat pneumatic system can be applied to pneumatic systems for seat massage such as lumbar support massage, leg support massage, back massage, and shoulder massage.
