Description

[0001] ARMREST FOR VECHICLE [0002]

One embodiment of the present invention relates to a vehicle armrest.

In general, the arm rests placed on a vehicle are a device that allows a passenger to raise his / her arm, and the driver or passenger can put his / her arm on the arm rest to take a comfortable posture in the car. An arm rest is provided between the driver's seat and the front passenger seat of the vehicle or in the center of the rear seat to store articles used by passengers or to support the arms of passengers seated on the front side. In the arm rest, a cup holder or a storage room is arranged to accommodate the occupant's articles.

Recently, there has been a demand for various ways of using the arm rest to keep the vehicle in a comfortable environment. In the conventional armrest, a pad portion made of a cushion material is disposed at a portion where a user's arm is placed, and a heating wire is disposed at a bottom surface of the pad portion. The heating wire is connected to the temperature sensor, and the heating wire generates heat according to the sensed temperature. Depending on the sensed temperature, the user of the armrest generates heat in the area where the arm is placed, allowing the user to use the vehicle in a warm environment in the winter.

However, in the existing armrest, no air was blown to the user side on the upper surface where the user's arm is placed. The face of the armrest is made to receive heat so that the user can feel the temperature only when the arm is leaned. Further, since the heating wire generates heat, when the user puts the arm on the armrest in the case of hot weather, the user may feel discomfort due to sweating in the user's arm.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for effectively explaining the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

The armrest for a vehicle according to the present invention can introduce air inside the vehicle and heat the air to be discharged into the vehicle again.

1 is a view showing an armrest for a vehicle according to an embodiment of the present invention.

1, an armrest 100 for a vehicle according to the present invention includes an air passage 20 into which air in a vehicle flows, air blown by a blower 22 disposed in the air passage 20, And a secondary heat exchanging member 32 disposed in the upper frame 12 constituting an upper portion of the armrest 10 to heat the air. Further, it may include a control unit 60 for controlling the heating of the primary heat exchange member 31 and the secondary heat exchange member 32.

And may include a frame 11 forming an outer shape of the armrest 100 and an upper frame 12 forming an upper portion. In the interior of the arm rest 100, the bulb portion 20, the air blowing device 22, and the primary heat exchange member 31 may be disposed.

The passage portion 20 includes the air inlet portion 21 so that air inside the vehicle can be introduced. The communicating portion 20 may have a shape such as a quadrangle that can have a space where the introduced air can stay. For example, the primary heat exchange member 31 may be disposed on any one of the three clogged surfaces. Therefore, air can be blown only toward the primary heat exchange member (31). A blowing device (22) can be disposed in the bulb (20). The air blowing device 22 can recirculate the air introduced into the bulb 20 to the inside of the vehicle. The air in the air passage 20 can be blown toward the primary heat exchanging member 31 by the air blowing device 22. [

The primary heat exchanging member 31 may be disposed on one side of the bulb 20 and occupy one side of the bulb 20. The primary heat exchange member 31 can heat the air. The air existing inside the passage portion 20 is blown by the air blowing device 22 and the air can be heated by the primary heat exchange member 31 disposed on all the one side surface of the passage portion 20. [ The heated air can flow toward the upper frame 12 through the inside of the armrest 100. [ The primary heat exchange member 31 may have a surface surface treated with a material containing at least one of alumina, magnesium oxide, sodium oxide, zirconium oxide, potassium oxide, graphene, and carbon nanotubes (CNT).

The upper frame 12 constitutes the upper part of the armrest 100. A plurality of air holes 13 are formed in the upper frame 12 so that the heated air can be discharged into the vehicle. The air blow holes 13 may be formed in the upper frame 12 such that the heated air can be uniformly discharged into the vehicle. In addition, the blow hole 13 may be formed in a hole of an appropriate size for evenly discharging the heated air. For example, the air blowing holes 13 may be formed in a plurality of fine holes and formed at narrow intervals.

The secondary heat exchange member 32 may be disposed on the upper frame 12 to heat the upper surface of the armrest 100. The secondary heat exchange member 32 may be disposed between the upper frame 12 and the cover member 51 surrounding the upper frame 12 and the secondary heat exchange member 32 may be disposed in the upper frame 12 Or more. For example, the secondary heat exchanging members 32 may be arranged alternately on the plurality of blowing holes 13 formed in the upper frame 12. When the secondary heat exchange member 32 is disposed on the air blowing hole 13, air blown in the armrest 100 can be discharged to the inside of the vehicle through the air blowing hole 13. Therefore, since the air primarily heated by the primary heat exchange member 31 passes through the secondary heat exchange member 32 and is discharged, the secondary heat exchange member 32 can once again heat the air. The secondary heat exchange member 32 may include at least one of a hot wire heater and an area heating element.

The cover member 50 may surround the entire upper frame 13 on which the secondary heat exchange member 32 is disposed. The cover member 50 is made of a material such as leather so that the user can feel comfortable when the user's arm touches the cover member.

Further, the secondary heat exchanging member 32 may be provided with a cushion member 51. The cushion member 51 may be disposed on the surface of the secondary heat exchange member 32 that contacts one surface of at least one of the upper frame 12 and the cover member 50. [ In addition, at least one through hole (not shown) may be formed in the cushion member 51 so that the heated air discharged through the air blowing hole 13 can be discharged to the inside of the vehicle. For example, the cushion member 51 is disposed between the secondary heat exchange member 32 and the cover member 50 so as to prevent the secondary heat exchange member 32 from being visually shown to the user outside the cover member 50 , It is possible to prevent burns due to direct heat transfer and to discharge warm air.

The air inside the vehicle is introduced into the armrest 100 to be heated, discharged again into the vehicle, and air can be recirculated. The air introduced into the airflow passage 20 through the air inlet 21 can be blown by the air blowing device 22. [ The air blown by the air blowing device 22 is heated by the primary heat exchanging member 31 and the air heated by the primary heat exchanging member 31 passes through the interior of the armrest 100 to the upper frame 12 And can be discharged to the formed blow hole 13. In addition, the surface of the arm rest 100 can be heated by the secondary heat exchange member 32 formed on the upper frame 12, and the heated air can be discharged into the vehicle.

2 is a view illustrating a primary heat exchanging member according to an embodiment of the present invention.

Referring to FIG. 2, the primary heat exchange member 31 may have a shape in which a heat ray 312 is disposed in the housing 311. The hot wire 312 may be disposed at a predetermined inclination from one side of the housing 311 to the other side, and may be disposed at one side from the other side. And may be arranged repeatedly from one side of the housing 311 to the other side and from one side to the other side. The predetermined slope may be set within an acute angle. The housing 311 may be formed as an empty space other than where the heat ray 312 is disposed, so that air can pass through the housing 311. Therefore, the air introduced into the airflow passage 20 can be heated by passing through the hot wire 312 of the primary heat exchange member 31 by the air blowing device 22.

The armrest 100 according to the present invention may include a control unit 60 for controlling the heating of the primary heat exchange member 31 and the secondary heat exchange member 32. The control unit 60 sets the temperature of the primary heat exchange member 31 and the secondary heat exchange member 32 to the temperature control unit 61 for setting the temperatures of the primary heat exchange member 31 and the secondary heat exchange member 32, And a heating control unit 62 for monitoring whether or not the detected temperature corresponds to the temperature.

The temperature control unit 61 can set the temperature to a predetermined level. The predetermined step may be a predetermined value or it may be manually set by the user.

The user can operate the temperature to the predetermined level by the temperature control unit 61. [ The predetermined step of the temperature preset in the temperature control unit 61 may be determined by at least one of a current, a voltage and a resistance. The temperature control unit 61 includes an adjusting circuit (not shown) for adjusting a control signal including at least one of a current, a voltage and a resistance inputted to the primary heat exchanging member 31 and the secondary heat exchanging member 32 .

The regulating circuit can regulate a signal pulse including pulse with modulation and a process identifier (PID) input to the primary heat exchanging member 31 and the secondary heat exchanging member 32.

Further, the regulating circuit may include a plurality of signal lines corresponding to predetermined steps to transmit the control signals inputted to the primary heat exchanging member 31 and the secondary heat exchanging member 32. The plurality of signal lines may be determined according to the step of distinguishing the signals input to the heat exchange members 31 and 32. For example, in accordance with a signal input to the heat exchange members 31 and 32, a signal line may be formed in a stepwise manner, such as a signal line to be inputted at the first stage of the signal and a signal line to be inputted at the second stage.

The heating control unit 62 can monitor the temperatures of the heat exchange members 31 and 32 so that the temperatures set in the primary heat exchange member 31 and the secondary heat exchange member 32 can be maintained respectively. The heating control unit 62 may include a safety device (not shown) for shutting off the power applied to the primary heat exchange member 31 and the secondary heat exchange member 32 when the temperature rises above a predetermined temperature. The safety device may include a switching device (not shown) for interrupting and applying power by a predetermined set value. The predetermined set value of the safety device can be determined by a safety detection signal including at least one of temperature, current and resistance. For example, a safety device can set a predetermined set value by a series of safety detection signals such as temperature, current, and resistance as a primary limit value and a secondary limit value. When the first limit value is reached, the signal input to the heat exchange members 31 and 32 can be blocked. When the second limit value is reached, the signal input to the heat exchange members 31 and 32 can be re-applied. Specifically, the first limit value may include a first set temperature, and when the first set temperature is exceeded, a signal input to the heat exchange members 31 and 32 is cut off, thereby forcibly cutting off the power supply. The secondary limit value may include a second set temperature and the second set temperature may be set to a temperature lower than the first set temperature. Accordingly, when the temperature reaches the second set temperature, the signal to the heat exchange members 31 and 32 can be applied to re-apply the power.

And a display unit (not shown) for displaying to the user the temperature of the air inside the vehicle or the heated air discharged into the vehicle.
