Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and more specifically, to a high-performance automobile seat ventilation system and an automobile seat. Background Art

[0002] With the popularization of automobiles, the comfort of seats inside automobiles has received increasing attention, and seat ventilation devices can significantly improve the comfort of users during riding. Existing automobile seat ventilation devices generally include a fan and a ventilation bag, and the ventilation bag is used to guide air flow to blow out from through holes on a seat foam body, so as to play a role in ventilation. In order to prevent the ventilation bag from being squeezed by the seat and causing poor air outlet, a mesh three-dimensional porous structure such as a sandwich mesh or ventilation sponge is usually arranged inside the ventilation bag to support the ventilation bag. However, on the one hand, the ventilation system adopting the ventilation bag has a complex structure and high cost; on the other hand, the internal structure of the ventilation bag generates resistance to the air flow, greatly reducing the ventilation effect.

[0003] Therefore, how to reduce the ventilation cost and improve the ventilation efficiency is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a high-performance automobile seat ventilation system, which can reduce the ventilation cost and improve the ventilation working efficiency.

[0005] To achieve the above purpose, the utility model proposes a high-performance automobile seat ventilation system, including:

[0006] A seat foam body: One side surface of the seat foam body is a human contact surface, and an air duct groove is formed inside the side of the seat foam body far away from the human contact surface. The projection of the air duct groove on the human contact surface is in a tree shape. The air duct groove includes an air inlet, a main trunk and a plurality of branch trunks. The air inlet, the main trunk and each branch trunk are all communicated with each other. A plurality of ventilation holes are formed on the side of the seat foam body close to the human body, and each ventilation hole is communicated with the air duct groove;

[0007] A fan: The air inlet of the fan is communicated with the outside, and the air outlet of the fan is communicated with the air inlet;

[0008] A gasket: The gasket is arranged on the side of the seat foam body far away from the human body, and the circumferential edge of the gasket is hermetically connected with the seat foam body. A first through hole is arranged on the gasket, and the first through hole is used for the fan to send air into the air duct groove.

[0009] In this utility model, by directly opening an air duct groove in the seat foam, the interior of the air duct is unobstructed, with small air resistance and improved ventilation efficiency. On the other hand, the structure of the air duct groove replaces the ventilation bag used in the prior art, reducing production costs. In this solution, the shape of the air duct groove is reasonably set. The projection of the adopted air duct groove on the human contact surface is tree-shaped. Compared with the conventional air duct groove with a vertical and horizontal orientation, the tree-shaped air duct is more conducive to the flow of gas. With less power, the air flow can be sent to the seat surface, which helps to improve the ventilation work efficiency and reduce energy consumption.

[0010] Preferably, each branch main duct inclines away from the air duct opening, and the included angle between each branch main duct and the main duct is 35° - 50°.

[0011] By reasonably setting the included angle between each branch main duct and the main duct with the above structure, the resistance of the air flow in the channel can be further reduced, and the ventilation work efficiency can be improved.

[0012] Preferably, the cross-sectional area of the main duct gradually decreases from the end close to the air duct opening to the end far from the air duct opening.

[0013] As the air flow in the air duct changes from large to small, the cross-sectional area of the main duct gradually decreases, which can ensure that the air flow out of each ventilation hole is more uniform.

[0014] Preferably, a groove matching the shape of the blower is provided on the side of the seat foam away from the human contact surface. The blower is arranged in the groove, and the first through hole is arranged at the position of the air inlet of the blower.

[0015] The blower is embedded in the seat foam. On the one hand, it improves the space utilization rate, and on the other hand, it can also reduce the blower noise.

[0016] Preferably, the high-performance automotive seat ventilation system further includes a first semiconductor module. The first semiconductor module includes a first housing with openings at both ends and a first semiconductor sheet. The first semiconductor sheet is arranged in the first housing. The two working surfaces of the first semiconductor sheet and the inner wall of the first housing enclose relatively independent first and second cavities.

The gasket is provided with a second through hole for communicating the second air outlet with the outside at the position corresponding to the second air outlet.

[0017] With the above structure, by corresponding the two working faces of the semiconductor sheet to two relatively independent cavities, the air blown by the fan passes through one of the cavities, takes away the cold / heat, and is sent into the air duct groove of the seat foam to achieve the purpose of refrigeration / heating, while the air flow in the other cavity correspondingly takes away the heat / cold and is discharged outside the seat.

[0018] Preferably, the first housing includes a heat insulation plate, and the heat insulation plate and the two working faces of the first semiconductor sheet enclose the first cavity and the second cavity.

[0019] Using the heat insulation plate can avoid energy loss generated by the semiconductor operation.

The heat dissipation grilles are connected to the inner wall of the heat insulation plate and the working faces of the first semiconductor sheet, and the direction of the holes formed by the heat dissipation grilles is consistent with the ventilation direction of the first cavity and the second cavity.

[0021] Using the heat dissipation grilles can maximize the utilization of the space in the cavity and promote heat exchange between the air flow blown by the fan and the heat dissipation grilles.

[0022] Preferably, the high-performance automotive seat ventilation system further includes a first support frame and a second semiconductor module. The fan is fixed on the first support frame, and the first support frame is fixed on the side of the seat foam away from the human contact surface; the second semiconductor module includes a second housing with openings at both ends and a second semiconductor sheet. The second semiconductor sheet is arranged in the second housing, and the two working faces of the second semiconductor sheet and the inner wall of the second housing enclose relatively independent first and second inner cavities. One end opening of the second housing is connected to the air outlet of the fan, and the other end opening of the second housing includes a first air guide port and a second air guide port. The first air guide port is connected to the outside, and the second air guide port is connected to the air duct opening through the first through hole.

[0023] Preferably, the high-performance automotive seat ventilation system further includes a second support frame and a wind guiding member. The fan is fixed on the second support frame, and the second support frame is fixed on the side of the seat foam away from the human contact surface; one end of the wind guiding member is connected to the air outlet of the fan, and the other end of the wind guiding member is connected to the air duct opening through the first through hole.

[0024] The fan can be directly installed on the seat through the support frame.

[0025] Preferably, the fan includes a volute provided with the air inlet and the air outlet, a rotating impeller is provided in the volute, a graphene heating sheet and a controller are provided in the volute, and the graphene heating sheet and the motor connected to the impeller are electrically connected to the controller through a wiring harness, so that the controller can control the power on and off of the graphene heating sheet.

[0050] Embodiment 1

[0051] As Figures 1 to 6 shown, a high-performance automotive seat ventilation system includes a seat foam body 100, a blower 2, and a gasket 3. One side surface of the seat foam body 100 is the human contact surface. A duct groove 11 is formed inside the side of the seat foam body 100 away from the human contact surface. The projection of the duct groove 11 on the human contact surface is in a tree shape. The duct groove 11 includes an air inlet 111, a main duct 112, and a plurality of branch ducts 113. The air inlet 111, the main duct 112, and each branch duct 113 are all in communication. A plurality of ventilation holes 12 are provided on the side of the seat foam body 100 close to the human body. Each ventilation hole 12 is in communication with the duct groove 11. Specifically, each ventilation hole 12 is uniformly arranged relative to the duct groove 11 to make the air outlet more uniform and the customer experience more comfortable.

[0052] The air inlet 21 of the blower 2 is in communication with the outside, and the air outlet 22 is in communication with the air inlet 111. In this embodiment, the blower 2 is a centrifugal blower 2. The air inlet 21 is located on the axis of the centrifugal blower 2, and the air outlet 22 is located tangentially to the centrifugal blower 2. During operation, outside air is inhaled into the centrifugal blower 2 along the axis and then discharged tangentially.

[0053] The gasket 3 is arranged on the side of the seat foam 100 away from the human body. The circumferential edge of the gasket 3 is hermetically connected to the seat foam 100. A first through hole 31 is arranged on the gasket 3, and the first through hole 31 is used for the blower 2 to send air into the air duct groove 11. In some specific embodiments, the gasket 3 can be made of a material with poor air permeability. In this embodiment, the gasket 3 is made of hot-pressed felt.

[0054] In some specific embodiments, each branch duct 113 is inclined in a direction away from the air duct opening 111, which can further reduce the resistance of the air flow in the air duct and improve the ventilation efficiency. In this embodiment, the included angle between each branch duct 113 and the main duct 112 is set between 35° and 50°. The cross-sectional area of the main duct 112 gradually decreases from the end near the air duct opening 111 to the end far from the air duct opening 111. As the air flow in the air duct changes from large to small, the cross-sectional area of the main duct 112 of the air duct groove 11 gradually decreases, ensuring that the air flow enters each branch duct 113 more evenly, so that the air blows out more evenly from each ventilation hole 12. Specifically, in this embodiment, by setting the main duct 112 of the air duct groove 11, the width gradually decreases from the air duct opening 111 to the end far from the air duct opening 111.

[0055] In this embodiment, a groove 13 matching the blower 2 is arranged on the side of the seat foam 100 away from the human body contact surface. The blower 2 is arranged in the groove 13, and the first through hole 31 is correspondingly arranged at the position of the air inlet 21 of the blower 2. The blower 2 is embedded in the seat foam 100. On the one hand, it can improve the space utilization rate, and on the other hand, it can also reduce the noise of the blower 2. When in the working state, the outside air is inhaled by the blower 2 through the first through hole 31 from the air inlet 21, and then sent into the air duct groove 11 through the air outlet 22 and the air duct opening 111, and finally blown out through each ventilation hole 12.

[0056] In some specific embodiments, the seat foam 100 can be a backrest foam or a seat cushion foam. In this embodiment, the seat foam 100 is a backrest foam.

[0057] Embodiment 2

[0058] See Figure 2 、 Figures 5 to 9, a high-performance automotive seat ventilation system, which is different from Embodiment 1 in that: it further includes a first semiconductor module 4. The first semiconductor module 4 includes a first housing 41 with openings at both ends and a first semiconductor sheet 42. The first semiconductor sheet 42 is disposed within the first housing 41. The two working surfaces of the first semiconductor sheet 42 and the inner wall of the first housing 41 enclose relatively independent first and second cavities 43 and 44. The semiconductor module used in the present invention is a thermoelectric cooler (TEC). Utilizing the Peltier effect of semiconductor materials, its working principle is: when an electric current passes through a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer will occur between the two ends. The heat generated by the electric current will be transferred from one side of the TEC to the other side, generating a "hot" side and a "cold" side on both sides of the TEC. Therefore, the hot side and the cold side of the first semiconductor module 4 are isolated in different cavities within the two independent first and second cavities 43 and 44 formed by the two working surfaces ("hot" side and "cold" side) of the first semiconductor and the first housing 41. One end opening of the first housing 41 is in communication with the air outlet 22 of the blower 2. The other end opening of the first housing 41 includes a first air outlet 45 and a second air outlet 46. The first air outlet 45 is in communication with the first cavity 43, and the second air outlet 46 is in communication with the second cavity 44. The first air outlet 45 is in communication with the air duct opening 111. At the position corresponding to the second air outlet 46 of the gasket 3, there is a second through hole 32 for communicating the second air outlet 46 with the outside. At this time, the blower 2 sucks in the outside air, which enters the first semiconductor module 4 through the air outlet 22. A part of the air flow passes through the first cavity 43 to carry away the heat / cold in the first cavity 43, forming hot air / cold air, which enters the air duct groove 11 through the first air outlet 45 and the air duct opening 111 and then is discharged through each ventilation hole 12 to achieve the seat heating / cooling effect; another part of the air flow passes through the second cavity 44 to carry away the cold / heat in the second cavity 44, forming cold air / hot air, which is discharged outside the seat through the second air outlet 46 and the second through hole 32. The heat / cold generated by the two working surfaces of the semiconductor is respectively isolated in the independent first and second cavities 43 and 44, without interference with each other, and the switching between cooling and heating can be achieved by changing the direction of the electric current. As is well known, a TEC semiconductor usually has four leads, arranged in sequence along the length direction of the semiconductor sheet. The two leads at both ends are connected to the power supply interface, and the two middle leads are the temperature control signal interfaces.

[0059] In this embodiment, the first housing 41 further includes a heat insulation plate 47. The heat insulation plate 47 and the two working surfaces of the first semiconductor chip 42 enclose a first cavity 43 and a second cavity 44. In some specific embodiments, the heat insulation plate 47 can be made of heat insulation materials such as a vacuum heat insulation plate, a glass fiber layer, or a foam material layer. The use of the heat insulation plate 47 can reduce the heat exchange between the first cavity 43 and the second cavity 44 and the outside, which is beneficial to the transfer of heat / cold generated by the semiconductor material to the required position and avoids power loss of the semiconductor chip.

[0060] In some specific embodiments, heat dissipation grilles 48 can be respectively arranged in the first cavity 43 and the second cavity 44. The heat dissipation grilles 48 are connected to the inner wall of the heat insulation plate 47 and the working surfaces of the first semiconductor chip 42. The direction in which the holes surrounded by the heat dissipation grilles 48 are formed is consistent with the ventilation direction of the first cavity 43 and the second cavity 44. Specifically, in this embodiment, the heat dissipation grilles 48 adopt a parallel structure, with one side connected to the heat insulation plate 47 and the other side connected to the first semiconductor chip 42. The parallel structures are arranged in sequence and evenly, and the spaces between adjacent structures and the inner wall of the heat insulation plate 47 and the working surfaces of the first semiconductor chip 42 form holes for ventilation. The heat dissipation grilles 48 are arranged inside the cavity for ventilation, which can enable the outside air blown by the fan 2 to exchange heat with the heat dissipation grilles 48 more efficiently, improving the heating / cooling efficiency; at the same time, the heat dissipation grilles 48 are connected to the two working surfaces of the heat insulation plate and the first semiconductor chip 42, providing a certain supporting role, and the direction of the formed holes is also consistent with the ventilation direction, without causing blockage of the air duct.

The fan 2 is fixed to the second support frame 7 by rubber studs and is fixed to the side of the seat foam 100 away from the human contact surface through the second support frame 7. One end of the wind guiding member 8 is communicated with the air outlet 22 of the fan 2, and the other end of the wind guiding member 8 is communicated with the air duct opening 111 through a first through hole 31. In the working state, the fan 2 blows the outside air in from the air suction port, passes through the air outlet 22, passes through the wind guiding member 8 and enters the air duct opening 111, and then blows out through the air duct groove 11 and then through each ventilation hole 12.

The second semiconductor sheet 52 is arranged in the second housing 51. The two working surfaces of the second semiconductor sheet 52 and the inner wall of the second housing 51 enclose relatively independent first and second inner cavities 53 and 54. One end opening of the second housing 51 is connected to the air outlet 22 of the blower 2, and the other end opening of the second housing 51 includes a first air outlet 55 and a second air outlet 56.

The graphene heating sheet and the motor connected to the impeller are respectively electrically connected to the controller through wiring harnesses. The controller can control the power on and off of the graphene heating sheet. By arranging the graphene heating sheet inside the blower 2 and controlling the power on and off of the graphene heating sheet through the controller, the air outlet 22 of the blower 2 can blow out cold air or hot air. For the specific installation structure of the graphene heating sheet, refer to the patent document of CN219601013U, which will not be elaborated here.

[0067] In some specific embodiments, the above blower 2 provided with a graphene heating sheet and a controller can also be fixed on the seat foam 100 through the first support frame 6 or the second support frame 7.
