Description

VEHICLE SEAT SYSTEM WITH CONDITIONING TEMPERATURE FUNCTION}

The present invention relates to a seat device for a vehicle, and more particularly, a temperature control function for preventing a rider from feeling uncomfortable due to a cold or hot seat when a vehicle is parked for a long time in a cold winter or a hot summer. It is related with the vehicle seat apparatus provided.

In the past, automobiles were regarded as merely a means of transporting people and goods, but they are accepted as a living space where people spend much time in their lives. Therefore, in the recent automobile industry, various efforts have been made not only to make an effort to improve driving performance and to secure safety, but also to provide a comfortable riding comfort and convenience to the rider.

In order to provide a comfortable ride, it is necessary to keep the indoor space comfortable in addition to mechanical shock absorption. Therefore, most of today's vehicles are equipped with air conditioning to realize air-conditioning, so that the indoor space can feel comfortable to the rider. And humidity can be maintained.

In general, the control of the room temperature by the air conditioner, which can be performed under the premise that the engine is driven, is provided with a plurality of warmed air (hereinafter, warm air) or coolly cooled air (hereinafter, cold air). It is made by supplying the indoor space through the duct. For this purpose, the air conditioner and the heater are built in. This type of indoor temperature control is to provide warmth or coolness to the occupant depending on the air convection.In order for the occupant to feel overall warmth or coolness and to obtain predetermined comfort, a certain amount of time is required after the air conditioner is operated. I need to go through. That is, it is difficult to quickly heat or cool a seat or steering wheel, etc., which come into contact with the human body through indoor temperature control by air convection. Therefore, when riding in a vehicle that has been parked in an outdoor space for a long time in a cold winter or a hot summer, the seat is very cold or very hot, and thus the rider feels a great discomfort immediately after boarding. Only after a considerable time has elapsed can it be resolved.

Specifically, in the case of a vehicle cooled by cold outdoor air for a long period of cold winter, a considerable time must pass after the engine is started so that the heater is heated to supply warm air. In addition, the fact that the warm air starts to supply does not mean that the indoor temperature can rise to an appropriate temperature in a short time throughout the indoor space. During this considerable period of time, the human body not only feels cold as it comes into contact with cold indoor air, but also comes into contact with parts of the body and parts of the body, especially when the surface temperature is cold enough to close to the temperature of indoor air. As it comes into contact with the sheet, it feels cold. In more detail, when in close contact with the sheet, heat transfer occurs between the human body and the surface of the sheet, not by convection, rather than conduction, so that the rider loses a lot of heat and feels a greater cold. That is, the first time the passenger rides on a vehicle cooled by cold outdoor air, the passenger feels colder by the cold surface sheet than by cold indoor air. In particular, if the material of the seat cover is leather, not textiles, it may be more so.

On the other hand, the indoor space of the vehicle heated by hot outdoor air and direct sunlight in the hot summer rises to a very high temperature of about 50 ° C to 60 ° C and, in some cases, may cause recall. In this case, the temperature of the indoor air can be relatively easily lowered relatively quickly through ventilation, but in order for the human body to feel cool, a considerable time is required until the internal components of the heated indoor space are cooled. During this considerable period of time, the human body not only feels the heat caused by contact with hot indoor air, but also comes into contact with parts of the human body and parts of the human body, especially the back and buttocks, whose surface temperature is close to the temperature of the indoor air. As it comes in close contact with the sheet, it feels heat. In more detail, when in close contact with the sheet, heat transfer occurs between the human body and the surface of the sheet, rather than conduction, rather than conduction, so that a lot of heat is transferred to the rider to feel a greater heat. That is, the first time a person rides a hotly heated vehicle, the rider feels more heat by the hot surface sheet than by the hot indoor air, and the discomfort felt by the hot seat lasts for a considerable time. Likewise, this is especially true if the seat cover is made of leather, not textiles.

For example, when riding in a vehicle that has been parked for a long time without driving in a cold or hot outdoor space, and when the indoor temperature is adjusted to an appropriate level by the air conditioner, In the meantime, there is an urgent need for effective temperature control of the sheet, which is a source of discomfort due to cold or heat as it comes into direct contact with the human body, which could not be realized through existing air conditioners.

Conventionally, there has been disclosed a technique for embedding an electrically driven heating wire in a sheet for direct and rapid heating of the sheet, or in a separate evaporator for constructing a cooling cycle for direct and rapid cooling of the sheet.

Although the above improvement may reduce the discomfort of the occupant to a large extent, the method of heating or cooling the local part of the seat may not only cause another kind of discomfort depending on the partial temperature imbalance, If there is a need for humidity control, such as sweating on the part of the human body that is in direct contact with the seat, there is no solution, there is still a limit to provide a comfortable ride to the passengers.

Furthermore, the direct heating and cooling of such seats can be accomplished by consuming significant energy, which is possible only when the engine is running, putting a strain on the capacity of vehicle components for the supply of electricity, such as batteries or alternators. Can give In addition, there may be a problem that a person is not realized by heating or cooling in advance before a person boards a vehicle.

As invented to solve the problems of the prior art as described above,

The present invention is independent of whether the engine is driven prior to the start of the ride so that even when the passenger is immediately parked in a vehicle that has been parked for a long time in a cold or heat state, the occupant does not feel severe discomfort by the cold or hot seat. In order to provide a vehicle seat device with a temperature control function, the temperature of the seat in the vehicle is properly maintained, and the temperature and humidity of the seat can be comfortably maintained while driving, thereby providing a more comfortable and comfortable ride comfort to the rider.

The switch door 53 is configured. Therefore, it is possible to perform both intake and exhaust through one blowing fan 45 which blows only in one direction.

Here, the first intake and exhaust switching door 51 and the second intake and exhaust switching door 53 are operated by independent actuators (not shown) which operate according to control commands of the control unit 80, respectively.

As shown in FIG. 3, the air blowing unit 50 controls the first intake and exhaust switching door 51 to block the intake port 47, open the exhaust flow path 41, and switch the second intake and exhaust. When the blower fan 45 is operated while the door 53 is controlled to block the intake flow passage 43 and the exhaust port 49 is opened, air is discharged from the collecting pipe 40 provided in the seat. The exhaust is performed by sucking and discharging to the outside. That is, the air is discharged along the flow path passing through the collecting pipe 40, the exhaust flow passage 41, the blowing fan 45, and the exhaust port 49 sequentially. Exhaust port 49 may also be connected to duct assembly 70, which will be described in detail below.

At this time, air is sucked along the flow path passing through the intake port 47, the blowing fan 45, the intake flow path 43, and the sheet sequentially. Also similar to the exhaust port 49, the inlet port 47 may be connected to the duct assembly 70, which will be described in detail below.

In addition, the duct assembly 70 is an internal air duct 55 communicating with the indoor space, an outdoor air duct 65 communicating with the outdoor space, and a flow path switching means for selectively blocking such an internal air duct 55 or the external air duct 65. (75). Therefore, one of the duct 55 and the outside air duct 65 is placed in the open state by the operation of the channel switching means 75, and any one of the open ducts is caused by air by the air blowing means 50.

Therefore, the seat apparatus according to the present invention is driven by the power supplied in a manner that can always be supplied through the solar cell 105, instead of being supplied with power from the main battery (not shown) basically provided in the vehicle, This not only reduces the load on the engine, but also reduces the capacity of components such as the main battery and the alternator. Of course, if necessary, power may be supplied from the main battery, and surplus power produced by the solar cell 105 may be supplied to other power consumption devices provided in the vehicle via the main battery.

As such, when the solar cell 105 is provided, the temperature control function of the seat may be performed without burdening the capacity of the main battery of the vehicle even when the engine is not driven, and utilizes solar energy as an energy source. Therefore, it is more preferable in that it is environmentally friendly.

Furthermore, the present invention further includes a remote controller 90. In this case, not only driving by directly riding the vehicle or using a time reservation function described in detail below, but also driving through a remote location is possible. Such a remote controller 90 may be incorporated into a vehicle remote control key, which may include an automatic door lock function and an automatic start function.

5 is a schematic cross-sectional view of a ventilation seat device for a vehicle according to a second embodiment of the present invention.

The ventilated seat device for a vehicle according to the second embodiment of the present invention, as shown in FIG. 5, is associated with an air conditioner 120 basically provided in a vehicle.

Specifically, unlike the case of the first embodiment described above, the bet duct 55 constituting the duct assembly 70 is not only open to the indoor space, but the output duct of the air conditioning device 120 provided in the vehicle It is provided with a structure that can be selectively connected to (125). In addition, the bet duct 55 further includes an auxiliary flow path switching means 135 for selectively switching to open to the interior space or connected to the output duct 125 of the air conditioning apparatus 120.

In this way, the auxiliary flow path switching means 135 and the bet duct 55 constituting the duct assembly 70 can be selectively connected to the output duct 125 of the air conditioning apparatus 120 provided in the vehicle. As it is provided, the seat 10 and the backrest portion which is in close contact with the human body directly in the cold air cooled through the air conditioner (not shown) of the air conditioning apparatus 120 or the warm air heated by the heater (not shown) 30 ) Can be supplied. Of course, the driving of the seat apparatus made in this manner may be performed in the running state, which is premised on the driving of the engine and the driving of the air conditioning apparatus, rather than the stopping of the engine.

The seat device for a vehicle having a temperature control function according to the present invention as described above operates to minimize the discomfort of the occupant due to a sudden temperature change even when the vehicle is directly parked in a vehicle parked for a long time without driving, It is possible to adjust the temperature of the seat at a point before the operation.

The vehicle seat apparatus having a temperature control function according to the present invention is driven through control by the controller 80 by receiving power through the solar cell 105. And, by selectively operating the blowing means 50 by the control unit blows air to the surface side of the seat portion 10 and the backrest portion 30 in close contact with the human body or of the seat portion 10 and the backrest portion 30 The seat temperature is controlled based on the ventilation function that sucks air from the surface. At this time, through the control of the flow path switching means 75 included in the duct assembly 70, either the internal air duct 55 or the external air duct 65 will be determined as the inlet or outlet of the air flow.

Looking at the driving time point, first, the vehicle seat apparatus having a temperature control function according to the present invention by using the power supplied in a manner that can always be supplied through the solar cell 105, in a manner that is always driven when the vehicle is not running Temperature control function can be performed. Of course, if the temperature of the surface of the sheet is determined to be appropriate when the controller 80 determines that the temperature information sensed by the provided temperature sensors 85, 86, 87 is controlled so as not to drive the sheet apparatus. Could be Such a method may be desirable when the driving and non-driving of the vehicle are continuously repeated.

However, this type of operation may be undesirable because the vehicle is wasting energy when the vehicle is not operated for a long time. Therefore, it is possible to use a time reservation function to repeat a specific point of time such as when going to work or going home. When set, the drive is controlled by the controller 80 to adjust the temperature of the sheet on the basis of the set time, that is, for a predetermined time before the set time, so that the rider does not feel uncomfortable when riding the set time. May be

In addition, in the event of unexpected need for driving of the vehicle, driving may be performed by operating the remote controller 90 arbitrarily at a remote location, and driving may be performed by a direct operation of the rider even after the riding point.

Hereinafter, a driving method of a vehicle seat apparatus having a temperature control function according to the present invention will be described in more detail according to a specific situation.

1) In the case of hot summer

When it is necessary to cool the seat, such as in a hot summer, when the temperature of the interior space of the vehicle increases due to the radiant heat of the sun, which is markedly different from the outdoor temperature, the air blowing unit 50 is in close contact with the human body. And controlled to blow air toward the surface side of the backrest 30. Then, the flow path switching means 75 is controlled to open the outside air duct 65 and block the inside air duct 55. Therefore, outdoor air having a temperature relatively lower than the temperature of the indoor air is introduced through the outdoor air duct 65 which serves as an inlet, and the outdoor air is supplied to the surface of the seat 10 and the backrest 30. . At this time, the effective heat transfer between the air and the sheet surface is effected by the forced convection by the blowing means 50, the surface of the seat portion 10 and the backrest portion 30 in contact with the human body reaches the outdoor temperature It can be cooled until, so that the rider can prevent the seat 1 from feeling uncomfortable due to the heat at the time of riding.

Such a sheet temperature control function may be performed at a time point selected from the driving time points described above. For example, if a certain point of time that is repetitive is set through the time scheduling function, such as summer work, when the indoor temperature can be maintained at an excessively high level according to seasonal characteristics, While the seat thermostat function may be controlled. In this case, a predetermined time before the set point at which the temperature control function is performed may be determined by direct setting or may be determined by the controller based on temperature information detected by the temperature sensors.

On the other hand, when the temperature control function is performed while driving, the air conditioner is operated according to the information sensed by the temperature sensors 85, 86 and 87 with the passage of time and the room temperature is increased as time passes. When it is determined that the temperature is lower than the outdoor temperature, the flow path switching means 75 may be controlled to block the outdoor air duct 65 and open the air duct 55, and through this control, the seat 1 is continuously cooled. Can be maintained.

On the other hand, when the bet duct 55 is provided with a structure that can be selectively connected to the output duct 125 of the air conditioning apparatus 120, as in the case of the second embodiment, the control of the auxiliary flow path switching means 135 Through the bet duct 55 is directly connected to the output duct 125 of the air conditioning apparatus 120, the seat portion 10 and the backrest which is in close contact with the human body cold air cooled by the air conditioner of the air conditioning apparatus 120 It becomes possible to supply to 30 directly. Thus, the seat 1 may be kept in a state capable of providing more comfort to the rider.

2) cold winter

When it is necessary to heat the sheet, such as in a cold winter, while controlling to supply power to the heating wire 25, the blowing means 50 is the surface of the seat portion 10 and the backrest portion 30 in close contact with the human body Controlled to blow to the side. Then, the flow path switching means 75 is controlled to block the outside air duct 65 and open the inside air duct 55. Accordingly, the seat portion 10 and the backrest portion 30 are locally heated by the built-in heating wire 25 around the portion adjacent to the heating wire 25, and the forced convection by the air blowing means 50 is achieved. Effective heat transfer is effected by the influence, the surface of the seat 10 and the backrest 30 which is in contact with the human body can be heated evenly so as not to cause discomfort, so that at the time of riding the passenger (1) It is possible to prevent the unpleasant feeling caused by the cold. In addition, the effect of forced convection is added to the local heating by the hot wire 25 and evenly heated without a partial temperature imbalance, thereby preventing an unpleasant feeling such as hotness felt in a part of the human body. .

The sheet temperature control function as described above may be performed at the time selected from the driving time point described above. For example, if you set a certain point of time that can be repeated, such as during or after work in winter, when the room temperature can be kept at an extremely low level depending on the seasonal characteristics, The sheet temperature control function may be performed for a predetermined time to control the heating of the sheet. Similarly, the predetermined time before the set point at which the temperature control function is performed may be determined by direct setting or may be determined by the controller based on temperature information detected by the temperature sensors.

On the other hand, according to the choice of the rider can be performed as described above temperature control function while driving.

On the other hand, when the bet duct 55 is provided with a structure that can be selectively connected to the output duct 125 of the air conditioning apparatus 120, as in the case of the second embodiment, the control of the auxiliary flow path switching means 135 Through the bet duct 55 is directly connected to the output duct 125 of the air conditioning apparatus 120, the seat portion 10 and the backrest which is in close contact with the human body warm air heated by the heater of the air conditioning apparatus 120 It becomes possible to supply to 30 directly. At this time, the operation of the heating wire may be stopped depending on the selection. Thus, the seat 1 may be kept in a state capable of providing more comfort to the rider.

3) If sheet drying is required

Even if it is not cold and not hot, and the seat does not need to be heated or cooled, as the traveling time increases, the local temperature rise of the contact area is increased due to prolonged contact between the human body and the surface of the seat 10 and the backrest 30. In addition, the human body is sweating, and thus, a humid environment is formed in some areas of the seat part 10 and the backrest part 30 in direct contact with the human body, which may cause discomfort such as dampness or stickiness to the passenger. When sheet drying is necessary in this way, the blowing means 50 is controlled to suck air from the surface side of the seat portion 10 and the backrest portion 30 in close contact with the human body. In addition, the flow path switching unit 75 is controlled to open the outside air duct 65 and block the inside air duct 55 so that the humid air is discharged to the outdoor space so that the humid air does not remain in the indoor space. . Therefore, not only the surfaces of the seat 10 and the backrest 30 which are in contact with the human body can be kept dry, but also the humidity of the indoor air can be prevented from rising, which causes the body to feel wet or Unpleasant feelings such as stickiness can be promptly resolved.

Exceptionally, when the betting duct is provided with a structure that can be selectively connected to the output duct 125 of the air conditioning apparatus 120, as in the case of the second embodiment described above, control of the auxiliary flow path switching means 135 according to the selection Through the bet duct 55 to be directly connected to the output duct 125 of the air conditioning device 120, the seat portion 10 which is in close contact with the human body dry air removed from the air conditioner of the air conditioning device 120 and It may also be driven in a manner of supplying directly to the backrest 30. Thus, the seat 1 may be kept in a state capable of providing more comfort to the rider.

The seat device for a vehicle having a temperature control function according to the present invention can control the temperature of the seat surface in close contact with the human body before the boarding point for driving, evenly as a whole in various ways according to the situation. It can also be used to adjust the temperature and humidity of the seat surface while running. Therefore, when riding in a vehicle that has not been parked for a long time in cold winter or hot summer, not only can the rider feel uncomfortable, but the seat can always be optimally maintained during driving. In order to provide a more comfortable and comfortable ride for the passenger. In addition, it is very hygienic because it is possible to prevent the accumulation of contaminants such as dust and the like in the vents of the seat and the vents of the seat cover through the repetitive change of the flow direction through the proper control of the blowing means. Could be.

Although the present invention has been described in detail only with respect to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention, and such changes and modifications belong to the appended claims. It will be natural.
