The present invention relates to a method of controlling an armrest and an armrest.

Generally, the interior parts of an automobile are composed of an instrument panel, a built-in floor and ceiling, a sun visor, a glove box, an arm rest, and a door trim. Among the built-in components of such an automobile, the armrest is a simple one to a large one that covers only a part of a shift lever or a parking brake lever provided in a tunnel portion of a floor panel between a driver's seat and an assistant driver's seat, A radio, a stereo, a heater control, a small water storage bag, and a box part with a lid with a pad on the rear side, with an osh tray or switch for the rear seat.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is merely an example and the present invention is not limited thereto.

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.

For example, although a heating element of an embodiment to be described later is an example of a heating wire which is a linear heating element, it is possible to apply an area heating element. Further, a soundproofing device for preventing noise and vibration by the blowing fan is shown on the lower side of the fan of the blowing fan, but this position is only one embodiment, and various modifications can be made by those skilled in the art.

1, at least one of the heating unit 300 and the infrared heater 20 shown in FIG. 1 is used. Unlike the infrared heating unit 20 shown in FIG. 1, the heating unit 320, In the case of the rest 2, it may mean only the heating element 300. However, in the embodiment of the present invention, the heating unit 320 is described as including at least one of the heating element 300 and the infrared heater 20. [

1 is a perspective view showing an armrest 2 according to an embodiment of the present invention.

The armrest (2) can house an arm of a human body part and also includes a storage space for storing the object. Generally, the armrest 2 is provided with a seat, and when installed in a vehicle, the armrest 2 can be installed on at least one of the left side or the right side of the driver or the passenger. When installed in a vehicle, it is capable of direct contact with the human body and functions to control the air conditioning environment inside the vehicle. Referring to FIG. 1, for the air conditioning environment, the armrest 2 may include a blowing fan (200 of FIG. 2) for forced forced convection inside the vehicle, and air A through hole 411 may be formed so that the through hole 411 can be discharged. The air discharged to the through holes 411 may be discharged to the outside of the armrest 2 via the heat generating element 300 capable of heat exchange with the air to raise the air temperature inside the vehicle.

In addition, the heating element 300 included in the armrest 2 can heat-exchange with the air to raise the temperature of the air through the convection, thereby raising the temperature of the air outside the armrest 2. Furthermore, since the heating element 300 is disposed on the upper side of the armrest 2, heat can be transmitted from the outer side of the upper side of the armrest 2 to the arm through conduction while the arm of the human body is being held. Of course, this example corresponds to the case where the human body comes into contact with the upper side of the armrest 2, and the heating body 300 is arranged at another position to perform heat transfer by contact with the other side of the armrest 2 It is possible.

The control unit 33 may further include a control unit 33 for controlling the temperature and the discharge speed of the air discharged to the outside of the armrest 2 from the user. The operation unit 33 may include, for example, a temperature control button capable of determining the temperature of the air discharged by the user and a wind speed control button capable of determining the air discharge amount. Further, when the temperature control button is operated, the temperature of the heating element 300 may be raised. If the temperature of the heating element 300 rises above the temperature determined by the user during the temperature rise or overheats exceeding the predetermined temperature, It is possible to control such that the condition for overheating such as the power supplied to the heating element 300 is cut off by the overheat preventing means is not satisfied.

In addition, the armrest 2 may further include a display unit 500. 1, the display unit 500 and the operation unit 33 can be independently positioned at different points in a separate configuration, though the display unit 500 is formed together with the operation unit 33. [ In addition, the display unit 500 can display a temperature according to the air flow rate according to the rotational speed of the blowing fan 200 and the degree of heat generation of the heating element 300 with audible or visual information. For example, in the case of a display, it may be a means for displaying the information as time information.

On the other hand, the armrest 2 may further include a controller 50. The control unit 50 may be located inside or outside the armrest 2 and may be connected to the blowing fan 200 and may be connected to at least one of the infrared heater 20 and the heating element. Here, the connection may be a connection through the sensing unit, and the sensing unit may be an internal temperature sensing unit, an external temperature sensing unit, and an operation sensing unit. The internal temperature sensing unit is located inside the case 100 and connected to the heating element 300 or the infrared heater 20 to sense the heating temperature and transmit the sensed heating temperature to the controller 50. The external temperature sensing unit is located outside the case 100 to sense the internal temperature of the vehicle and transmit the sensed temperature to the control unit 50. Also, the motion sensing unit senses information related to the operation of the heating element 300 or the infrared heater 20. [ For example, it is possible to detect information such as whether the heating element 300 or the infrared heater 20 is operated and the operation time. And may transmit the information related to the detected operation to the control unit 50. Further, the motion sensing unit may transmit information related to the operation of the blowing fan 200 and the operation of the blowing fan 200 to the control unit 50.

The controller 50 receives the temperature information and the operation information, and controls the blower fan 200 and the heating element 300 based on a predetermined criterion. The predetermined criterion is a temperature that is transmitted to the control unit 50 by the external temperature sensing unit when the temperature preset by the user is set to, for example, 30 degrees in winter for the air conditioning environment inside the vehicle. 50 to calculate the temperature difference between the current temperature and the target temperature (30 degrees), and operate the heating element 300 or the infrared heater 20 and the fan to compensate the calculated temperature difference. When the inside temperature sensed by the outside temperature control unit 50 reaches 30 degrees which is the target temperature after the heating element 300, the infrared heater 20 and the fan are operated, the control unit 50 reduces the discharge of warm air It is possible to control to stop the operation.

However, when the temperature sensed by the external temperature sensor is lower than a predetermined lower limit temperature, the operation of the ventilation fan 200 may not be performed. Here, the predetermined lower limit temperature corresponds to a case where the temperature is low enough to hardly affect the air conditioning environment inside the vehicle even if it is heated by the heating unit 320 and discharged to the outside of the armrest 2. In this case, And can transmit only the heat of conduction due to the heat generated by the heating element 300 through the casing. The larger the difference between the outside temperature of the armrest 2 and the heating temperature of the heating unit 320, the more the heating temperature may increase to reach the target temperature, and the increased heating temperature may lead to overheating, And at the same time, unnecessary power consumption can be prevented without consuming power when the heat generation efficiency is low.

The control of the control unit 50 will be described later in detail with reference to FIG. 2 and FIG.

2 is a flowchart illustrating a control procedure of the heating unit 320 controlled by the control unit 50 according to an embodiment of the present invention.

The heating unit 320 includes at least one of the heating unit 300 and the infrared heater 20 according to an embodiment of the present invention and therefore the heating unit 320 May be one of the heating element 300 and the infrared heater 20. [ An unillustrated sensing unit senses an external temperature sensing unit for sensing a temperature outside the armrest 2, an internal temperature sensing unit for sensing a heating temperature of the heating unit 320, and an operating time of the heating unit 320 And a motion detection unit. The sensing unit may be connected to the controller 50 to transmit the temperature information and the operation time information to the controller 50.

Referring to Fig. 2, the armrest 2 can be controlled by the control unit 50, including four steps. Power is applied to the heating unit 320 in sequence and the temperature is sensed by the sensing unit in the heating unit 320. The sensed temperature is compared with a preset temperature P3, And a process (P4) of operating and stopping the heating unit 320 and the blowing fan 200 to maintain a predetermined temperature range.

Here, the process P1 in which power is applied to the heating unit 320 may be a battery of the vehicle, for example, to which electric power supplied by an external or internal power supply unit is applied. The heating unit 320, which is supplied with power by the power supply unit, may generate heat.

Then, the heating unit 320 senses the temperature by the sensing unit (P2), and the controller (50) can compare the sensed temperature with a predetermined temperature (P3). For example, if the temperature of the heating unit 320 is lower than the predetermined temperature, the heating of the heating unit 320 may be stopped by a method such as shutting off the power when the temperature of the heating unit 320 is higher .

In addition, the stop of heat generation or heat generation of the heating unit 320 can be controlled to maintain a predetermined temperature range, and heat can be applied to the air within the temperature range, so that damage to the arm rest 2 due to overheating can be prevented have.

3 is a flowchart showing a control procedure of the blowing fan 200 controlled by the control unit 50 according to an embodiment of the present invention.

Referring to FIG. 3, the control unit 50 can control the operation of the blowing fan 200 based on information received from the sensing unit. The blowing fan 200 can be determined based on the temperature of the heating unit 320 or the operating time of the heating unit 320.

The process according to the temperature of the heating unit 320 may include four steps. In the four steps, power is applied to the armrest S1, whether or not the sensing unit is operating the sensing unit 320 is sensed S2, and if the sensing unit 320 is operating, 320 may be sensed by the internal temperature sensing unit S3-1 and the blower fan may be operated when the temperature of the heating unit 320 reaches a predetermined temperature or higher.

Here, in the step of applying the armrest power (S1), power is applied to the armrest (2), and the power supply to the peripheral device (2) requiring power supply such as the blowing fan (200) and the heating unit Quot; power supply "

When the heating unit 320 is not operated, the heating unit 320 may be operated again in the step S2 of sensing the heating unit operation. In this case, the heating unit 320 may be operated while power is supplied from the previous stage S1. Process can be performed. Accordingly, in the case where it is sensed that the heating unit 320 is operated in the heating unit operation detection step S2, the heating unit temperature sensing step S3-1 may be performed. In this case, the predetermined temperature may be compared with the heating temperature in the heating unit 320. When the temperature of the heating unit 320 does not reach the predetermined temperature in the process of overheating the heating unit 320, , And then the heating portion 320 can be heated. That is, the heating of the heating unit 320 can be maintained until the heating temperature of the heating unit 320 reaches a predetermined temperature. When the temperature reaches a predetermined temperature by the heating unit 320 which continuously generates heat, it is possible to perform a blowing fan operation step (S4) in which the blowing fan 200 operates. Here, the predetermined temperature may be a temperature at which the air is heated to a predetermined temperature when the air is heated by the heating unit 320 and discharged to the outside of the armrest 2 by the blowing fan 200 . For example, the predetermined temperature may be 70 to 110 degrees.

The process of discharging the air outside the armrest 2 may be related to the temperature of the heating unit 320 as well as the operating time of the heating unit 320.

This process can also include a four-step process. In the four steps, power is applied to the armrest S1, whether or not the sensing unit is operating the sensing unit 320 is sensed S2, and if the sensing unit 320 is operating, (S3-1). When the temperature of the heating unit 320 reaches a predetermined temperature or more, the blowing fan is operated (S4) .

When the heating unit 320 is not operated, the heating unit 320 may be operated again in the step S2 of sensing the heating unit operation. In this case, the heating unit 320 may be operated while power is supplied from the previous stage S1. Process can be performed. Accordingly, if it is detected that the heating unit 320 is operated in the heating unit operation detection step S2, the heating unit operation time detection step S3-2 may be performed. When the predetermined time has elapsed from the time when the heating unit 320 is detected to be operated, a step S4 of operating the blowing fan 200 may be performed. The time required to reach the temperature at which the air can be heated. That is, the heating of the heating unit 320 can be maintained until the heating temperature of the heating unit 320 reaches a predetermined temperature. The predetermined time may be, for example, 5 to 30 seconds. The heating unit 320, which continuously generates heat, may perform a blowing fan operation step (S4) in which the blowing fan 200 operates when a predetermined time has elapsed. Here, the preset time may be a temperature at which the air is heated to a predetermined temperature when the air is heated by the heating unit 320 and discharged to the outside of the armrest 2 by the blowing fan 200 .

Meanwhile, in the control method of the armrest according to the embodiment of the present invention, the external temperature of the armrest 2 is sensed by the external temperature sensor and the sensed temperature is transmitted to the controller 50, The operation of the heating unit 320 and the blowing fan 200 can be controlled so as to reach the target temperature which is an external temperature of the armrest 2.
