This application claims priority to and the benefit of Korean Patent Application No. 10-2020-0155252, filed on Nov. 19, 2020, the entire contents of which are incorporated herein by reference.
The present disclosure relates to a power seat operating device having a seesaw type switch for a vehicle.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Generally, a power seat for a vehicle includes a seat cushion for seating, a seatback against which the back leans, and a headrest supporting a neck and a head, as an essential configuration, and additionally, further includes power mechanism configurations for adjusting various positions of a seat.
Particularly, the side portion of the power seat is mounted with a switch module for adjusting the seat cushion, the seatback, and the like to various locations.
The switch module adopts a structure in which several switches are combined and arranged for the forward and backward movement adjustment in the seat, the height adjustment in the seat cushion, the extension adjustment for the front portion of the seat cushion, the bolster angle adjustment in the seatback, the reclining adjustment in the seatback, the support direction adjustment in a lumbar support installed within the seatback, and the like.
Further, a touch sensor is embedded in each switch of the switch module, such that the selection state and operating direction of the switch may be displayed through a display around a driver seat together with the sensing operation of the touch sensor when the user's hand touches the switch.
Therefore, the user may easily, visually recognize the selection state and the operation direction of the switch displayed on the display while keeping an eye on the front during driving.
That is, the user may easily, visually recognize the selection state and the operation direction of the switch displayed on the display, thereby eliminating the user's inconvenience such as turning the head toward the switch module while bending the upper body for directly confirming the operating state of the switch module mounted on the side portion of the seat.
Meanwhile, the switch module may be composed of a first switch for the adjustment in a total of six directions such as the forward and backward movement adjustment in the entire seat (two directions), the up and down of the front portion of the seat cushion (two directions), and the vertical height adjustment in the seat cushion (two directions), a second switch for the extension adjustment for the front portion of the seat cushion (two directions), a third switch for the reclining adjustment in the seatback (two directions), a fourth switch for the bolster angle adjustment in the seatback (two directions), a fifth switch for the support direction adjustment in the lumbar support (four directions), and the like.
Further, touch sensors may be embedded in the first to fifth switches.
Therefore, when the touch operation is performed in which the user's hand touches the surface of one switch of the first to fifth switches desired by the user to operate, a sensing signal of the touch sensor embedded in the corresponding switch is output to a controller, and subsequently, the arrow indicating the operation direction of the power seat according to the operating of the switch touched by the user's hand may be displayed on the display by the control of the controller.
Therefore, the operation direction of the power seat according to the operating of the switch touched by the user's hand may be displayed on the display, such that the user may visually, easily recognize the operation direction of the power seat according to the switch operating.
For example, when the touch operation is performed in which the user's hand touches the first switch for the adjustment in a total of six directions such as the forward and backward movement adjustment in the seat (two directions), the up and down of the front portion of the seat cushion (two directions), and the height adjustment in the seat cushion (two directions), as illustrated in
However, we have discovered that even if the user touches any portion of the first switch, a total of six arrows guiding the operation direction of the power seat by the operating of the first switch are simultaneously displayed on the display, such that there is a disadvantage in that the user does not accurately receive the guidance for the operation direction of the first switch and the operation direction of the power seat actually desired by the user.
Likewise, even in the case of the second switch to the fifth switch, even if the user touches any portion of the second to fifth switches, all operation directions of the power seat according to the operating of the second to fifth switches are simultaneously displayed on the display by the arrows, such that there is a disadvantage in that the user does not accurately receive the guidance for the operation directions of the second to fifth switches and the operation direction of the power seat actually desired by the user.
For example, even if the touch operation is performed in which the user's hand touches the surface of the rear end of the first switch for the forward movement adjustment (e.g., pushing the first switch forward) of the seat, a total of six arrows guiding the operation direction of the power seat according to the operating of the first switch are simultaneously displayed on a display, such that the user may recognize that his/her hand touches the first switch, but there is a disadvantage in that the user does not accurately receive the guidance for the operation direction of the first switch for the forward movement adjustment in the seat and the operation direction of the power seat (e.g., the forward movement adjustment in the seat) according to the operating of the first switch.
That is, if the touch operation is performed in which the user's hand touches the surface of the rear end of the first switch for the forward movement adjustment (e.g., operating of pushing the first switch forward) of the seat, the user may accurately recognize the operation direction of the first switch for the forward movement adjustment in the seat when only one arrow guiding the forward movement adjustment in the seat is displayed on the display, but as described above, a total of six arrows guiding all operation directions of the power seat which may be operated by the operating of the first switch are simultaneously displayed on the display, such that there is a problem in that the user does not accurately receive the guidance for the operation direction of the first switch desired by the user, thereby rather increasing the inconvenience when the user handles the switch.
The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure and accordingly it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.
The present disclosure provides a power seat operating device having a seesaw type switch for a vehicle, which may embed a plurality of touch sensors for guiding each operation direction of a power seat for each seesaw type switch of a switch module for operating the power seat such that one arrow guiding the operation direction of the power seat according to the sensing operation of each touch sensor is displayed on a display, thereby improving the convenience of the switch operating of the user, such as accurately guiding the operation direction of the power seat according to the operating of the switch to the user, and accurately recognizing the selection state and operation direction of the switch desired by the user.

Hereinafter,
The side portion of a seat (e.g., one side portion of a seat cushion) is mounted with a switch module 100 including seesaw type first to seventh switches 110, 120, 130, 140, 150, 160, 170 for operating the operation of a power seat.
As illustrated in
The seesaw type refers to a type in which one side end of the switch moves downward and the other side end thereof moves upward when the operating of selectively pressing one side end of both ends of the switch is performed, the push button type refers to a type of vertically pressing and operating the switch, and the rotary knob type refers to a type of rotating and operating the switch at a predetermined angle.
Particularly, a plurality of touch sensors for guiding each operation direction of the power seat are embedded in each of the first switch to the seventh switch 110, 120, 130, 140, 150, 160, 170 configuring the switch module 100.
When a sensing signal of the touch sensor in which the sensing operation is performed of the plurality of touch sensors is received in a main controller, the main controller determines the operation direction of the power seat and the operation direction of the switch according to the sensing signal of the corresponding touch sensor, and then transmits a control signal for the display on a display.
Therefore, a seat image may be displayed on the display and one or more arrow images guiding the operation direction of the power seat and the operation direction of the switch determined by the main controller may be displayed.
Therefore, the user may accurately recognize the switch selection state and the switch operation direction, and the operation direction of the power seat according to the switch operating while watching the seat and arrow images displayed on the display, thereby improving the switch operating convenience of the user.
The seesaw type first switch 110 is configured for the forward and backward movement operating of the seat, and includes a first switch cover 111 forming the appearance.
Both side ends of the first switch cover 111 are formed with a 1-1st electrode exposure hole 111-1 and a 1-2nd electrode exposure hole 111-2, respectively.
Particularly, the bottom surface portion of the first switch cover 111 has a 1-1st touch sensor 112-1 and a 1-2nd touch sensor 112-2 spaced apart from each other and attached.
At this time, a 1-1st electrode 116-1 inserted into the 1-1st electrode exposure hole 111-1 and exposed to the outside is formed to protrude from the 1-1st touch sensor 112-1, and a 1-2nd electrode 116-2 inserted into the 1-2nd electrode exposure hole 111-2 and exposed to the outside is formed to protrude from the 1-2nd touch sensor 112-2.
Therefore, when the user's hand touches one side surface or the other side surface of the first switch cover 111, the touch sensing may be performed by contacting the 1-1st electrode 116-1 or the 1-2nd electrode 116-2.
Further, the bottom surface portion of the first switch cover 111 is mounted with a first moving block 113 capable of seesaw motion.
Further, a 1-1st plunger 114-1 and a 1-2nd plunger 114-2 are connected to the bottom portions of both sides of the first moving block 113 to be movable upward and downward, respectively.
At this time, since the main controller 180 is provided in a printed circuit board (PCB) type, predetermined locations of the main controller 180 are mounted with a pair of tact switches 181 pressed by the 1-1st plunger 114-1 and the 1-2nd plunger 114-2.
Further, the 1-1st touch sensor 112-1 and the main controller 180 are electrically conductively connected by a 1-1st conductive spring 115-1 such that the sensing signal of the 1-1st touch sensor 112-1 may be transmitted to the main controller 180.
Likewise, the 1-2nd touch sensor 112-2 and the main controller 180 are electrically conductively connected by a 1-2nd conductive spring 115-2 such that the sensing signal of the 1-2nd touch sensor 112-2 may be transmitted to the main controller 180.
Therefore, when the user's hand touches one side surface of the first switch cover 111, the sensing of the 1-1st touch sensor 112-1 is performed by contacting the 1-1st electrode 116-1, and the sensing signal of the 1-1st touch sensor 112-1 is output to the main controller 180 through the 1-1st conductive spring 115-1.
Subsequently, the main controller 180 determines the operation direction of the power seat and the operation direction of the switch according to the sensing signal of the 1-1st touch sensor 112-1 as the forward movement direction of the seat.
Subsequently, the main controller 180 transmits a display command signal according to the signal determined as the forward movement direction of the seat to the display 200, such that as illustrated in
Therefore, when watching the display 200, the user may easily recognize that the forward movement operation of the seat may be performed when currently pressing one side surface of the first switch cover 111 in the state of touching the hand on the one side surface of the first switch cover 111.
At this time, when the user actually presses the one side surface of the first switch cover 111 in the state of touching the hand on the one side surface of the first switch cover 111, the 1-1st plunger 114-1 presses the tact switch 181 while moving downward, and subsequently, the main controller 180 recognizes a pressed signal of the tact switch 181 and applies a driving signal to a motor for the forward movement operation of the seat.
Of course, when the user releases a force of pressing the one side surface of the first switch cover 111, the 1-1st plunger 114-1 and the first switch cover 111 move upward to the original locations by an elastic reaction force of the tact switch 181.
On the other hand, when the user's hand touches the other side surface of the first switch cover 111, the sensing of the 1-2nd touch sensor 112-2 is performed by contacting the 1-2nd electrode 116-2, and the sensing signal of the 1-2nd touch sensor 112-2 is output to the main controller 180 through the 1-2nd conductive spring 115-2.
Subsequently, the main controller 180 determines the operation direction of the power seat and the operation direction of the switch according to the sensing signal of the 1-2nd touch sensor 112-2 as the backward movement direction of the seat.
Subsequently, the main controller 180 transmits a display command signal according to the signal determined as the backward movement direction of the seat to the display 200, such that as illustrated in
Therefore, when watching the display 200, the user may easily recognize that the backward movement operation of the seat may be performed when currently pressing the other side surface of the first switch cover 111 in the state of touching the hand on the other side surface of the first switch cover 111.
At this time, when the user actually presses the other side surface of the first switch cover 111 in the state of touching the hand on the other side surface of the first switch cover 111, the 1-2nd plunger 114-2 presses the tact switch 181 while moving downward, and subsequently, the main controller 180 recognizes the pressed signal of the tact switch 181 and applies a driving signal to the motor for the backward movement of the seat.
The seesaw type second switch 120 is configured for operating the vertical height adjustment (two directions) of the seat, and includes a second switch cover 121 forming the appearance.
Both side ends of the second switch cover 121 are formed with a 2-1st electrode exposure hole 121-1 and a 2-2nd electrode exposure hole 121-2, respectively.
Particularly, the bottom surface portion of the second switch cover 121 has a 2-1st touch sensor 122-1 and a 2-2nd touch sensor 122-2 spaced apart from each other and attached.
At this time, a 2-1st electrode 126-1 inserted into the 2-1st electrode exposure hole 121-1 and exposed to the outside is formed to protrude from the 2-1st touch sensor 122-1, and a 2-2nd electrode 126-2 inserted into the 2-2nd electrode exposure hole 121-2 and exposed to the outside is formed to protrude from the 2-2nd touch sensor 122-2.
Therefore, when the user's hand touches one side surface or the other side surface of the second switch cover 121, the touch sensing may be performed by contacting the 2-1st electrode 126-1 or the 2-2nd electrode 126-2.
Further, the bottom surface portion of the second switch cover 121 is mounted with a second moving block 123 capable of seesaw motion.
Further, a 2-1st plunger 124-1 and a 2-2nd plunger 124-2 are connected to the bottom portions of both sides of the second moving block 123 to be movable upward and downward, respectively.
At this time, since the main controller 180 is provided in a printed circuit board (PCB) type, predetermined locations of the main controller 180 are mounted with a pair of tact switches 182 pressed by the 2-1st plunger 124-1 and the 2-2nd plunger 124-2.
Further, the 2-1st touch sensor 122-1 and the main controller 180 are electrically conductively connected by a 2-1st conductive spring 125-1 such that the sensing signal of the 2-1st touch sensor 122-1 may be transmitted to the main controller 180.
Likewise, the 2-2nd touch sensor 122-2 and the main controller 180 are electrically conductively connected by a 2-2nd conductive spring 125-2 such that the sensing signal of the 2-2nd touch sensor 122-2 may be transmitted to the main controller 180.
Therefore, when the user's hand touches one side surface of the second switch cover 131, the sensing of the 2-1st touch sensor 122-1 is performed by contacting the 2-1st electrode 126-1, and the sensing signal of the 2-1st touch sensor 122-1 is output to the main controller 180 through the 2-1st conductive spring 125-1.
Subsequently, the main controller 180 determines the operation direction of the power seat and the operation direction of the switch according to the sensing signal of the 2-1st touch sensor 122-1 as an ascending movement direction of the seat.
Subsequently, the main controller 180 transmits a display command signal according to the signal determined as the ascending movement direction of the seat to the display 200, such that as illustrated in
Therefore, when watching the display 200, the user may easily recognize that the ascending movement operation of the seat may be performed when the user's hand currently presses one side surface of the second switch cover 121 in the state of touching the one side surface thereof.
At this time, when the user actually presses the one side surface of the second switch cover 121 in the state of touching the hand on the one side surface of the second switch cover 121, the 2-1st plunger 124-1 presses the tact switch 182 while moving downward, and subsequently, the main controller 180 recognizes a pressed signal of the tact switch 182 and applies a driving signal to the motor for the ascending movement operation of the seat.
When the user releases a force of pressing the one side surface of the second switch cover 121, the 2-1st plunger 124-1 and the second switch cover 121 move upward to the original locations by an elastic reaction force of the tact switch 182.
On the other hand, when the user's hand touches the other side surface of the second switch cover 121, the sensing of the 2-2nd touch sensor 122-2 is performed by contacting the 2-2nd electrode 126-2, and the sensing signal of the 2-2nd touch sensor 122-2 is output to the main controller 180 through the 2-2nd conductive spring 125-2.
Subsequently, the main controller 180 determines the operation direction of the power seat and the operation direction of the switch according to the sensing signal of the 2-2nd touch sensor 122-2 as the descending movement direction of the seat.
Subsequently, the main controller 180 transmits a display command signal according to the signal determined as the descending movement direction of the seat to the display 200, such that as illustrated in
Therefore, when watching the display 200, the user may easily recognize that the descending movement operation of the seat may be performed when currently pressing the other side surface of the second switch cover 121 in the state of touching the hand on the other side surface of the second switch cover 121.
At this time, when the user actually presses the other side surface of the second switch cover 121 in the state of touching the hand on the other side surface of the second switch cover 121, the 2-2nd plunger 124-2 presses the tact switch 182 while moving downward, and subsequently, the main controller 180 recognizes a pressed signal of the tact switch 182 and applies a driving signal to the motor for the descending movement.
The seesaw type third switch 130 is configured for operating the front portion up and down adjustment (two directions) of the seat cushion, and includes a third switch cover 131 forming the appearance.
Both side ends of the third switch cover 131 are formed with a 3-1st electrode exposure hole 131-1 and a 3-2nd electrode exposure hole 131-2, respectively.
Particularly, the bottom surface portion of the third switch cover 131 has a 3-1st touch sensor 132-1 and a 3-2nd touch sensor 132-2 spaced apart from each other and attached.
At this time, a 3-1st electrode 136-1 inserted into the 3-1st electrode exposure hole 131-1 and exposed to the outside is formed to protrude from the 3-1st touch sensor 132-1, and a 3-2nd electrode 136-2 inserted into the 3-2nd electrode exposure hole 131-2 and exposed to the outside is formed to protrude from the 3-2nd touch sensor 132-2.
Subsequently, when the user's hand touches one side surface or the other side surface of the third switch cover 131, the touch sensing may be performed by contacting the 3-1st electrode 136-1 or the 3-2nd electrode 136-2.
Further, the bottom surface portion of the third switch cover 131 is mounted with a third moving block 133 capable of seesaw motion.
Further, a 3-1st plunger 134-1 and a 3-2nd plunger 134-2 are connected to the bottom portions of both sides of the third moving block 133 to be movable upward and downward, respectively.
At this time, since the main controller 180 is provided in a printed circuit board (PCB) type, predetermined locations of the main controller 180 are mounted with a pair of tact switches 183 pressed by the 3-1st plunger 134-1 and the 3-2nd plunger 134-2.
