Description

Technical Field

[0001] The present invention relates to the technical field of ventilated seats. Specifically, it relates to a fully automatic ventilated seat and its ventilation control method. Background Art

[0002] An automobile seat is an item for the driver to sit on inside the automobile cab. The seat mainly consists of a seat cushion, a backrest, and a headrest, providing a good riding experience for the driver and passengers. When the driver and passengers sit on the seat cushion for a long time, after long-term contact with the seat, it is easy for the driver and passengers' buttocks to sweat, reducing the riding experience of the driver and passengers. Therefore, the automobile seats in the prior art are generally equipped with seat heating and ventilation functions to enable passengers to have a better ride.

[0003] The ventilated seats in the prior art usually refer to installing an air exchange fan device at the bottom of the seat cushion, so that the air exchange fan device introduces the air flow in the cab into the seat cushion and discharges the air flow through the seat cushion, enabling the seat cushion to have the function of ventilation and air exchange. However, in the process of using the ventilated seats in the prior art, the air flow is usually heated at the same time, so that while the seat cushion meets the ventilation requirement, it also has an additional heating function to improve the driving experience of the driver and passengers in cold weather. However, in the process of heating the air flow, usually when the air flow flows in the seat cushion and contacts the air flow with an electric resistance wire, the air flow is heated. However, due to the large change in environmental temperature, even within a day, there are great changes in the environment inside the vehicle cab. Therefore, the air volume and temperature of ventilation and heat dissipation of the seat are inconsistent at different times. And for the control during the working process of the ventilated seat in the prior art, it is difficult to ensure timely and targeted adjustment of the ventilation air flow. Summary of the Invention

[0016] The working principle and beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, when ventilation is required for the seat cushion area of the seat, first, a temperature sensor is used to detect the temperature inside the cab. When it is determined that the temperature inside the cab needs to be heated, after attracting the air flow into the installation support frame, the air flow is conveyed into the air flow heating mechanism through the air flow distribution component. After the air flow is fully heated, it is discharged through the air flow discharge mechanism. After the air flow enters the seat cushion, the ventilation and heating function of the seat cushion is realized. And according to the temperature inside the cab detected by the temperature sensor, the contact area between the air flow and the electric resistance wire in the air flow heating mechanism is adjusted, so that when the air flow quickly passes through the area of the electric resistance wire, the temperature rise of the air flow is controlled, and the control of the air flow temperature is realized.

[0018] 2. In the present invention, when the temperature inside the cab is relatively high and seat cushion heating is not required, in order to improve the conveying speed of the air flow, the air flow distribution mechanism can be used to directly convey the air flow into the air flow discharge mechanism, saving the time for heating the air flow and improving the smoothness of air flow discharge.

[0019] 3. In the present invention, after directly conveying the air flow inside the cab into the air intake groove body, in order to filter the dust of the gas, under the traction of the suction fan, after the air flow enters the air intake groove body, it first impacts on one side of the filter layer of the triangular support frame, so that the dust in the air flow is first adsorbed onto the filter layer. Then the air flow flows along the side wall of the triangular support frame, so that the air flow always remains in contact with the filter layer of the triangular support frame, and the dust in the air flow is effectively adsorbed.

[0020] 4. Therefore, during the use of this fully automatic ventilation seat, it always corresponds to the ambient temperature inside the cab, so as to adapt to the passenger's sitting process under different environmental conditions, and make the ventilation performance and temperature requirements of the seat cushion correspond to the ambient temperature.

Specific embodiments

[0034] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0035] Embodiment 1, as Figures 1 to 11As shown in the figure, this embodiment proposes a fully automatic ventilated seat, which includes a seat cushion 1, a backrest 2, and a headrest 3. The backrest 2 is arranged on the seat cushion 1, and the headrest 3 is arranged at the top of the backrest 2. The seat cushion 1, the backrest 2, and the headrest 3 are all common seat components in the automobile cab in the prior art. The mutual installation among the seat cushion 1, the backrest 2, and the headrest 3, as well as the method and structure for installing them in the automobile cab, are all well-known prior art devices to those skilled in the art.

[0036] It further includes that a receiving chamber is arranged inside the seat cushion 1, an installation support frame 4 is arranged inside the receiving chamber, an air inlet slot is communicated between the installation support frame 4 and the seat cushion 1, and a temperature sensor 5 is arranged inside the air inlet slot. The temperature sensor 5 is a prior art device for detecting the temperature inside the automobile cab in the prior art and is also well-known to those skilled in the art. After using the temperature sensor 5 to detect the temperature inside the automobile cab, the ventilation flow rate of the subsequent seat cushion 1 and the heating change of the seat cushion 1 can be judged according to the ambient temperature inside the automobile cab.

[0037] An air flow distribution mechanism is arranged on one side of the installation support frame 4 close to the air inlet slot. The air flow distribution mechanism is used to control the conveying position of the air flow. The air flow distribution mechanism includes an air inlet trough body 6, an air flow dust filtering component, a slope-shaped exhaust trough 8, and an air flow distribution component. The air inlet trough body 6 is fixedly connected to one side of the installation support frame 4 inside the receiving chamber close to the air inlet slot. An air inlet fan 7 is arranged inside the air inlet trough body 6. When it is necessary to convey the air flow into the installation support frame 4, the air inlet fan 7 is started to make the air flow enter the air inlet trough body 6.

[0038] The air flow dust filtering component is arranged between the air inlet trough body 6 and the air inlet slot. The air flow dust filtering component is used to filter the air flow entering the installation support frame 4. The air flow dust filtering component includes a triangular support frame 9. The triangular support frame 9 is fixedly connected inside the air inlet trough body 6. Filtering layers 10 are arranged on both sides of the triangular support frame 9. A sealing plate 11 is fixedly connected between the top of the triangular support frame 9 and the air inlet trough body 6. A plurality of air inlet holes are opened on the sealing plate 11. A plurality of ventilation grooves 12 are opened on the filtering layer 10 corresponding to the plurality of air inlet holes on the side close to the sealing plate 11. After the air flow enters the air inlet trough body 6, the air flow first contacts the filtering layer 10 in the direction close to the air inlet slot, so that after the air flow enters the air inlet trough body 6, the air flow hits the filtering layer 10, adsorbing the dust in the air flow onto the filtering layer 10. Then the air flow continues to flow along the side wall area of the triangular support frame 9. When the air flow passes through the air inlet holes, the air flow contacts the ventilation grooves 12 on the filtering layer 10, making the dust in the air flow further stay on the other filtering layer 10, completing the dust filtering operation of the air flow.

[0039] On one side of the intake trough body 6 away from the intake trough opening, there is a sloped exhaust trough 8 connected. An air flow distribution component is arranged in the sloped exhaust trough 8. The air flow distribution component includes a closing plate 13, a driving structure, a closed cylinder 16, and a discharge cylinder 18. The top of the closing plate 13 is rotatably connected in the sloped exhaust trough 8 through a rotating shaft 14. The closing plate 13 fits against the inner wall of the sloped exhaust trough 8. A resilient sealing layer 15 is fixedly connected between one side of the top end of the closing plate 13 and one side of the inner top wall of the sloped exhaust trough 8. A driving structure is arranged between the closing plate 13 and the top of the sloped exhaust trough 8. The driving structure includes a through chute 19 and a sliding member 23. A sliding toothed plate 20 is slidably connected in the through chute 19. A transmission gear 21 is engaged with the sliding toothed plate 20. The transmission gear 21 is rotatably connected in the through chute 19. A driving motor 22 is arranged in the through chute 19. The output end of the driving motor 22 is fixedly connected to the transmission gear 21. The top of the closing plate 13 is slidably connected with the sliding member 23. The bottom of the sliding toothed plate 20 is rotatably connected to the sliding member 23. When it is necessary to heat the air flow before discharging, start the driving motor 22 to drive the transmission gear 21 to rotate, so that the sliding toothed plate 20 drives the closing plate 13 to flip upward along the center point of the rotating shaft 14. The bottom of the closed cylinder 16 extends into the corresponding exhaust port 17. After the air flow enters the sloped exhaust trough 8, the air flow directly enters the installation cylinder 24;

[0040] A plurality of closed cylinders 16 are fixedly connected to the inner top wall of the sloped exhaust trough 8. A plurality of exhaust ports 17 are opened on the closing plate 13. The closed cylinders 16 cooperate with the corresponding exhaust ports 17. An air inlet is opened in the middle of the closed cylinder 16. The tops of the plurality of closed cylinders 16 are connected to a discharge cylinder 18. When the air flow does not need to be heated before discharging, the driving motor 22 can be started to drive the sliding toothed plate 20 to descend, so that the closing plate 13 flips downward along the center point of the rotating shaft 14. When the closing plate 13 flips downward and the resilient sealing layer 15 extends downward, the sloped exhaust trough 8 and the installation cylinder 24 are temporarily kept closed. At this time, the bottom of the closed cylinder 16 moves out of the exhaust port 17. After the air flow enters the sloped exhaust trough 8, the air flow is discharged into the upper side area of the closing plate 13 through the plurality of exhaust ports 17. The air flow enters between the closed cylinder 16 and the discharge cylinder 18 through the air inlet opened on the closed cylinder 16, so that the air flow does not need to be heated and directly enters the gas discharge mechanism.

[0041] An air flow heating mechanism is provided in the middle of the installation support frame 4. There is a connection between the air flow distribution mechanism and the air flow heating mechanism. The air flow heating mechanism includes an installation cylinder body 24 and electric resistance wires 25. The installation cylinder body 24 is connected to the slope-shaped exhaust groove 8. A plurality of electric resistance wires 25 are arranged in the installation cylinder body 24. An area control component is arranged between the installation cylinder body 24 and the plurality of electric resistance wires 25. The area control component is used to control the contact area between the air flow and the electric resistance wires 25. The electric resistance wires 25 are well-known prior art to those skilled in the art and are also prior art equipment for heating air flow in this field. After the air flow enters the installation cylinder body 24 through the slope-shaped exhaust groove 8 and contacts the electric resistance wires 25, the temperature of the air flow rises. When discharging the heated air flow, the ventilation and heating function of the seat cushion 1 is realized;

[0042] The area control component includes a turning plate 26, a through hole 28, and a driving electric cylinder 29. One side of the turning plate 26 is rotatably connected to the inside of the installation cylinder body 24 through a rotating seat 27. An elastic sealing layer 15 is also arranged between the other side of the turning plate 26 and the installation cylinder body 24. A plurality of through holes 28 corresponding to the electric resistance wires 25 are formed in the turning plate 26. The electric resistance wires 25 are arranged through the through holes 28. The driving electric cylinder 29 is rotatably arranged in the installation cylinder body 24 through a rotating seat 30. The output end of the driving electric cylinder 29 is rotatably connected to the turning plate 26 through a rotating shaft member 31. According to the actual temperature in the cab, the ventilation and heating temperature of the seat cushion 1 is selected. In order to adjust the temperature of the air flow, the driving electric cylinder 29 is started to drive the rotating shaft member 31 and the turning plate 26 to turn upward, so that the turning plate 26 turns upward along the center point of the rotating seat 27, and the length of the electric resistance wires 25 located in the upper area of the closing plate 13 is adjusted to make the air flow contact the appropriate area of the electric resistance wires 25.

[0043] An air flow discharging mechanism is also provided on the installation support frame 4. The air flow splitting mechanism and the air flow heating mechanism are both communicated with the air flow discharging mechanism. The air flow discharging mechanism includes a ventilation cylinder body 32, an exhaust cylinder body 34 and an exhaust pipe 36. The ventilation cylinder body 32 is arranged inside the installation support frame 4. A conveying pipe 33 is communicated between the ventilation cylinder body 32 and the installation cylinder body 24. The number of the exhaust cylinder bodies 34 is set to be multiple. The exhaust cylinder bodies 34 are arranged between the seat cushion 1 and the installation support frame 4. An air outlet groove 35 is formed at the top of the exhaust cylinder body 34. An exhaust pipe 36 is communicated with the ventilation cylinder body 32. A cut-off valve is arranged on one side of the exhaust pipe 36 close to the ventilation cylinder body 32. The exhaust pipe 36 extends into the exhaust cylinder body 34. A plurality of air outlet holes 37 are formed on the exhaust pipe 36. The air outlet holes 37 are located inside the exhaust cylinder body 34. A connecting pipe 38 is communicated between the discharge cylinder body 18 and the exhaust pipe 36. After heating the air flow, the air flow in the installation cylinder body 24 is conveyed into the ventilation cylinder body 32 through the conveying pipe 33. Then the air flow enters into the exhaust pipe 36 through the ventilation cylinder body 32, is discharged through the air outlet holes 37 and passes through the air outlet groove 35, so that the heated air flow enters into the seat cushion 1, completing the ventilation and heating of the seat cushion 1. And the ventilation cylinder body 32 can keep the corresponding area of the seat cushion 1 heated, realizing the heating operation of the seat cushion 1;

[0044] When it is not necessary to heat the air flow and directly discharge the air flow, the air flow is directly conveyed from the discharge cylinder body 18 into the exhaust pipe 36 through the connecting pipe 38, so that the normal temperature air flow is directly discharged through the exhaust pipe 36, realizing the ventilation operation of the seat cushion 1. Under the action of the cut-off valve, the air flow is prevented from entering into the ventilation cylinder body 32.

[0045] A plurality of support forks 39 are fixedly connected inside the installation support frame 4. When a passenger sits on the seat cushion 1, the seat cushion 1 will sag downward. Both the installation support frame 4 and the support forks 39 are made of carbon fiber material or plastic material with elastic deformation ability, keeping the seat cushion 1 elastic and avoiding damage to various components inside the installation support frame 4.

[0046] The working principle of this fully automatic ventilation seat: First, when the driver and passengers are sitting in the car, the temperature sensor 5 is used to detect the ambient temperature in the cab first, judge the ventilation and heating amount required by the seat cushion 1, and then start the intake fan 7 to convey the air flow in the cab into the intake trough body 6. After the air flow enters into the intake trough body 6, the air flow impacts on the dust filtering layer 10, adsorbing the dust in the air flow onto the dust filtering layer 10. Then the air flow continues to flow along the side wall area of the triangular support frame 9. When the air flow passes through the intake holes, the air flow contacts with the ventilation grooves 12 on the dust filtering layer 10, making the dust in the air flow further stay on another layer of the dust filtering layer 10, completing the dust filtering operation of the air flow;

[0047] After the air flow is filtered by dust, it enters the intake tank body 6, and then the air flow enters the slope-shaped exhaust tank 8. When it is necessary to heat the air flow before discharging, start the driving motor 22 to drive the transmission gear 21 to rotate, so that the sliding tooth plate 20 drives the closing plate 13 to turn upward along the center point of the rotating shaft 14. The bottom of the closed cylinder 16 extends into the corresponding exhaust port 17. After the air flow enters the slope-shaped exhaust tank 8, the air flow directly enters the installation cylinder 24. After the air flow enters the installation cylinder 24 through the slope-shaped exhaust tank 8, the air flow contacts the electric heating resistance wire 25, so that the temperature of the air flow rises. After heating the air flow, the air flow in the installation cylinder 24 is transported to the ventilation cylinder 32 through the delivery pipe 33. Then the air flow passes through the ventilation cylinder 32 and enters the exhaust pipe 36, and is discharged through the air outlet hole 37 and passes through the air outlet groove 35, so that the heated air flow enters the cushion 1, completing the ventilation and heating of the cushion 1.

[0048] When it is not necessary to heat the air flow, start the driving motor 22 to drive the sliding tooth plate 20 to descend, so that the closing plate 13 turns downward along the center point of the rotating shaft 14. When the closing plate 13 turns downward and the elastic sealing layer 15 extends downward, the slope-shaped exhaust tank 8 and the installation cylinder 24 are temporarily kept sealed. At this time, the bottom of the closed cylinder 16 moves out of the exhaust port 17. After the air flow enters the slope-shaped exhaust tank 8, the air flow is discharged into the upper side area of the closing plate 13 through a plurality of exhaust ports 17, and the air flow enters between the closed cylinder 16 and the discharge cylinder 18 through the air inlet opening provided on the closed cylinder 16, and the air flow is directly transported from the discharge cylinder 18 to the exhaust pipe 36 through the connecting pipe 38, so that the normal temperature air flow is directly discharged through the exhaust pipe 36, realizing the ventilation operation of the cushion 1.

[0049] Embodiment 2. Based on a fully automatic ventilation seat, this Embodiment 2 also proposes a ventilation control method for a fully automatic ventilation seat, including the following steps:

[0050] Step 1, temperature detection: After the driver and passengers sit on the cushion 1, use the temperature sensor 5 to sense the temperature in the cab to determine the ventilation and heating requirements of the cushion 1;

[0051] Step 2, air flow dust filtration: Start the intake fan 7 to transport the air flow in the cab to the intake tank body 6. After the air flow enters the intake tank body 6, the air flow impacts the dust filtration layer 10, adsorbing the dust in the air flow onto the dust filtration layer 10. Then the air flow continues to flow along the side wall area of the triangular support frame 9. When the air flow passes through the intake hole, the air flow contacts the ventilation groove 12 on the dust filtration layer 10, so that the dust in the air flow is further retained on another layer of the dust filtration layer 10, completing the dust filtration operation of the air flow.

[0052] Step 3. Divide the exhaust airflow: When the seat cushion 1 needs to be heated, start the drive motor 22 to drive the transmission gear 21 to rotate, so that the sliding tooth plate 20 drives the closing plate 13 to turn upward along the center point of the rotating shaft 14, and the bottom of the closed cylinder 16 extends into the corresponding exhaust port 17. After the airflow enters the slope-shaped exhaust groove 8, the airflow directly enters the installation cylinder 24. When the airflow does not need to be heated, start the drive motor 22 to drive the sliding tooth plate 20 to descend, so that the closing plate 13 turns downward along the center point of the rotating shaft 14. When the closing plate 13 turns downward and the elastic sealing layer 15 extends downward, the slope-shaped exhaust groove 8 and the installation cylinder 24 are temporarily kept sealed. At this time, the bottom of the closed cylinder 16 is removed from the exhaust port 17. After the airflow enters the slope-shaped exhaust groove 8, the airflow is discharged into the upper area of the closing plate 13 through a plurality of exhaust ports 17;

[0053] Step 4. Heat the airflow: After the airflow enters the installation cylinder 24 through the slope-shaped exhaust groove 8, the airflow contacts the electric heating resistance wire 25, and the temperature of the airflow rises;

[0054] Step 5. Control the temperature of the airflow: Start the drive electric cylinder 29 to drive the rotating shaft member 31 and the turning plate 26 to turn upward, so that the turning plate 26 turns upward along the center point of the rotating seat 27, adjust the length of the electric heating resistance wire 25 in the upper area of the closing plate 13, make the airflow contact the area of the electric heating resistance wire 25 above the turning plate 26, and control the contact area between the airflow and the electric heating resistance wire 25 to realize the control of the airflow temperature;

[0055] Step 6. Discharge the airflow: After heating the airflow, the airflow in the installation cylinder 24 is transported into the ventilation cylinder 32 through the delivery pipe 33.
