Description

Morphing type power window switch device of vehicle

The present invention relates to a power window switch device for a vehicle, and more particularly, to a morphing type power window switch device for a vehicle in which an operation unit appears on the surface of an armrest only when it is used.

A window is provided on the door of the vehicle for indoor lighting, and the window glass that shields the window is opened and closed by an electric lifting device.

A power window switch device is provided to control the operation of the electric lift device, and is usually installed on the upper surface of the armrest formed on the inner side of the door.

As shown in Fig. 1, the conventional power window switch device includes a total of four window glass opening and closing switches (1, 2, 3, 4) by a pair of front and rear. A disk-shaped select switch and a window lock switch may be further installed in front of these switches.

The driver can open and close the desired window glass by selecting one of the four switches and pushing or pulling (Push & Pull type).

As described above, the conventional power window switch device has a dedicated switch (1, 2, 3, 4) for each window glass, so the number of switches is large, the external configuration of the device is complicated, and the weight and size of the entire switch device There was a problem of increasing.

In addition, since four switches must be arranged in front and rear pairs in the same way as the four window glass positions to enable intuitive operation, the degree of design freedom is very low, and most of the vehicle's power window switch devices have similar appearances. Accordingly, although the power window switch device is a major interior element in a vehicle interior, it does not give a special sense of aesthetics.

Republic of Korea Patent Publication No. 10-1268697 (registered on May 22, 2013)

Accordingly, the present invention has been conceived to solve the above problems, and its purpose is to provide a morphing type power window switch device for a vehicle capable of simplifying the exterior configuration, reducing weight and size, and giving a new aesthetic sense to the occupants. There is this.

The present invention for achieving the above object, and a skin material attached to the armrest surface of the door trim; A flat base installed in the inner space of the armrest under the skin material; A guide installed upright at the end of the base; An elevating module installed on the upper part of the guide and guiding an up-and-down movement path by a guide; A capacitive touch sensor installed in the lifting module; A window switch installed on the upper surface of the touch sensor, the upper surface is convex upward, and made of a transparent material; And installed on the base, by raising the lifting module so that the window switch pushes up the skin material so that the protruding shape of the window switch appears on the skin material, or by lowering the lifting module, the window switch is spaced downward from the skin material. It includes a; motor for the protruding shape of the window switch to disappear from the outside of the skin material by so that.

A transfer male screw is formed on a rotation shaft of the motor, a lead nut having a transfer female screw is installed on a bottom surface of the lifting module, and the rotation shaft and the lead nut are screwed.

A guide groove is formed in the upper inner portion of the guide, and an insertion portion is formed in the lower outer portion of the lifting module, and the insertion portion is inserted into the guide groove to guide the vertical movement path.

A circuit board is installed on the upper surface of the bottom of the lifting module, and an LED is installed on the circuit board.

The touch sensor is made of a transparent material.

Prism may be applied as the window switch.

A light shielding material is attached to the rest of the upper surface of the touch sensor except for the window switch.

The skin material is pressed and expanded by the rise of the window switch to increase light transmittance, thereby allowing light emitted from the window switch to pass smoothly.

The control unit further includes a control unit receiving various window switch manipulation (contact) information from the touch sensor, driving the motor according to the manipulation information, raising and lowering the lift module, and controlling the light emission state of the LED.

A speaker and a vibration motor controlled by the control unit are further provided, and the vibration motor is installed in the lifting module, and the control unit generates different types of beeps and vibrations according to the window switch operation information.

According to the present invention as described above, since the window switch is provided as a single drag bar type switch, the external configuration of the power window switch device is greatly simplified.

As the four window switches are integrated into one switch, the internal configuration is simplified, and the weight and size of the device are reduced.

In addition, the window switch according to the present invention is a morphing type switch that appears on the surface of the armrest only when the user uses it. When the window switch is not used, the power window switch device is not visible on the surface of the armrest, so it is very neat.

In addition, when in use, a drag bar-type window switch pushes and protrudes from the bottom of the skin fabric of the armrest, so that the window switch can be distinguished tactilely, so it is convenient to use.

In addition, since the window switch emits light according to the opening/closing amount of the door, it is possible to accurately know the opening/closing amount of the window glass without looking at the actual window glass, and accordingly, the opening/closing amount can be easily adjusted as desired.

In the present invention, various modifications may be made and various embodiments may be provided, and specific embodiments will be illustrated in the drawings and described in detail. However, this is not intended to limit the present invention to a specific embodiment, it should be understood to include all changes, equivalents, and substitutes included in the spirit and scope of the present invention. The thicknesses of lines or sizes of components shown in the accompanying drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intentions or precedents of users or operators. Therefore, definitions of these terms should be made based on the contents throughout the present specification.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

2 and 3, the morphing type power window switch device according to the present invention is embedded in the upper surface of the armrest 6 provided in the door trim 5 on the driver's seat side.

FIG. 2 is a non-use state of the power window switch device, and FIG. 3 is a use state, wherein the power window switch device according to the present invention is invisible on the upper surface of the armrest 6 as shown in FIG. 2 when not in use. And, when in use, the window switch 10 appears in a visible state from the outside. It works in a so-called Morphing method.

In FIG. 3, only the window switch 10 that controls the amount of opening and closing of the window glass and the window lock switch 11 that maintains the locked state to maintain the current operating state of the window glass are shown, but the window glass to be opened and closed is shown. It goes without saying that a select switch (not shown) for selection may also be provided to operate in the same manner.

The configuration for the morphing operation as described above is as follows.

As shown in Figure 4, the morphing type power window switch device according to the present invention, the window switch 10, the base 20, the guide 30, the lifting module 40, the circuit board 50, the LED ( 60), a touch sensor 70, a light shielding material 80, a motor 90 and an armrest skin material 7 are included.

The base 20 has a substantially flat shape and forms the bottom of the power window switch device, and provides a place to install other components.

The guide 30 provides an installation place for the lifting module 40, secures a space for installing the motor 90 on the upper part of the base 20, and guides the vertical movement path of the lifting module 40. do.

The guide 30 may be a wall installed at the end of the base 20 in an upright state, and in this case, a guide groove 31 having a predetermined depth is formed in the upper inner portion of the guide 30. In response to the guide groove 31, an insertion portion 41 having a size capable of being inserted into the guide groove 31 is formed on the lower outer portion of the lifting module 40.

The guide groove 31 of the guide 30 and the insertion part 41 of the lifting module 40 are both formed in a linear direction perpendicular to the base 30, so that the guide 30 fixed to the base 30 ), the elevating module 40 can move in a stable path in the vertical direction.

On the other hand, as the guide 30, it goes without saying that a widely used linear motion guide may be used instead of a wall-type structure surrounding the end of the base 20 as described above. Linear motion guides, which are usually abbreviated as LM guides, include rails and moving blocks that move linearly along the rails, and when the rails are installed vertically on the base 20 and the lifting module 40 is fixed to the moving block, it is lifted. It is possible to accurately guide the vertical movement path of the module 40.

The lifting module 40 is moved up and down while being guided by the guide 30 as described above, wherein the circuit board 50, the LED 60, the touch sensor 70, the light shielding material 80, A window switch 10 is installed.

The circuit board 50 is installed on the upper surface of the bottom of the lifting module 40. The LED 60 is installed on the circuit board 50, and an electric circuit for driving the LED 60 is configured.

The LED 60 may emit light with R, G, B basic colors alone or a combination of them. It is operated by receiving power through an electric circuit of the circuit board 50.

The touch sensor 70 is installed above the LED 60 inside the lifting module 40, and is a capacitive type touch sensor that senses the movement of the driver's finger in contact with the window switch 10. It is a touch sensor with a general configuration used in smartphones.

The touch sensor 70 transmits the user's finger contact information (drag distance, contact time, contact position, etc.) through the window switch 10 to a control unit (not shown). The control unit controls the lighting of the LED 90 and the operation of the motor 90 by performing a pre-woven control logic according to the finger contact information transmitted from the touch sensor 70.

As the control unit, a control unit for controlling an opening amount of the window glass by controlling the driving motor of the window glass lifting device according to the finger contact information, that is, a manipulation signal of the window switch 10 may be used or may be provided separately.

In addition, the touch sensor 70 is made of a transparent material through which light generated from the LED 60 can pass.

A window switch 10 formed long along the front and rear direction of the power window switch device (same as the length direction of the armrest 6) is attached to the center of the upper surface of the touch sensor 70. The upper surface of the window switch 10 is formed in an upwardly convex curved surface.

The window switch 10 is installed on the upper surface of the touch sensor 70 to contact the user's finger, and is the same as the outermost surface layer of the screen in a general touch screen including a touch sensor.

As the window switch 10, a prism made of a transparent polycarbonate (PC) material may be used to smoothly diffuse the light of the LED 60 to the outside.

The light shielding material 80 is a fabric that does not transmit light and is attached to the upper surface of the touch sensor 70. However, the window switch 10 protrudes upward from the light shielding material 80 through a hole formed in the light shielding material 80.

Therefore, the light shielding material 80 covers the upper surface of the touch sensor 70 excluding the window switch 10 so that the light of the LED 60 can be emitted to the outside only through the window switch 10.

The motor 90 is installed on the upper surface of the base 20 with the rotation shaft 91 facing upward. The outer periphery of the rotation shaft 91 of the motor 90 is formed with a feed male screw. In other words, it is formed by a kind of lead screw. On the other hand, a lead nut 42 having a transfer female screw corresponding to the transfer male screw is mounted on the bottom of the bottom of the lifting module 40. The length of the lead nut 42 is sufficient if the window switch 10 is formed slightly longer than the ascending distance so as to secure an ascending distance to which the window switch 10 is in close contact with the armrest skin 7 and pushes it up.

The rotation shaft 91 of the motor 90 is screwed to the lead nut 42. Accordingly, when the motor 90 is operated, the lead nut 42 may move along the rotation shaft 91 along the rotation shaft 91 and rise or fall according to the rotation direction of the motor 90. The operation of the motor 90 is controlled according to the user's window switch 10 touch method. For example, it is possible to operate the motor 90 by maintaining a pressed state for a set time or by continuously tapping (double touch). In addition, when the above-described operation is applied, if the window switch 10 is in an emergency state in which it is lowered, it is rotated in the direction of raising the window switch 10, and if the window switch 10 is in an elevated state, the window switch 10 It goes without saying that the control logic is set in the control unit (not shown) to rotate in the downward direction.

The armrest skin material 7 is a skin material covering the surface of the armrest 6 as shown in FIGS. 2 and 3 and may be made of fiber fabric or leather having excellent elasticity and light transmittance. The armrest skin 7 is attached to the upper surface of the armrest 6 so as to cover the upper part of the power window switch device embedded in the armrest 6.

The light transmittance of the armrest skin material 7 varies depending on the degree of stretching, but the light transmittance is weak (almost none) when it is not stretched at all, and the light transmittance is increased when it is stretched. Therefore, in the state in which the window switch 10 is positioned at a predetermined distance apart from the lower part of the armrest skin material 7 (Fig. 4), the light emitted through the window switch 10 is transmitted to the armrest skin material 7 The window switch 10 is not visible from the outside because it does not pass well, and the armrest skin 7 is pushed by the window switch 10 in a state in which the window switch 10 is raised to the use position (Fig. 5). As it rises and increases, light transmittance is improved, so that light from the window switch 10 passes well, so that the window switch 10 can be seen from the outside.

On the other hand, when the window switch 10 is raised to the use state, the height of the protrusion that pushes and rises the skin material 7 in a flat state is about 3mm to 5mm. If the protruding height is lower than 3mm, the recognition ability to detect the window switch 10 through finger sense (touch) decreases, and if it is higher than 5mm, the protrusion is excessive and the aesthetic sense is lowered, and the adhesive part of the skin material 7 is separated. , There is a problem that the durable life of the skin material 7 is reduced.

In addition, it is appropriate that the appropriate thickness of the skin material 7 is 0.8mm to 1.2mm. If the thickness of the skin (7) is less than 0.8mm, the durability against abrasion is weak and the durability life is short.If it exceeds 1.2mm, the protruding shape is not clearly visible even when protruding by the window switch 10, as well as light transmittance. It is bad that the light generated from the window switch 10 is difficult to see, so that the length of the window switch 10 and the light emitting portion indicating the window opening amount cannot be properly identified.

On the other hand, it is preferable that the total thickness of the light shielding material 80 and the skin material 7 is 50mm or less. When the thickness is thicker than 50 mm, since the distance from the finger to the touch sensor 70 is too far to detect the capacitance of the finger, the sensitivity of the touch sensor 70 is deteriorated.

In addition, as described above, the window switch 10 may use a prism made of a transparent polycarbonate material. In this way, the light emitting portion (rod shape) is displayed by improving the illuminance of light emitted through the window switch 10. There is an effect of increasing the visibility of the light emitting unit).

In addition, the width of the window switch 10 is preferably 10mm ~ 15mm. If the width of the window switch 10 is less than 10 mm, it is not easy to operate, such as when the finger leaves the window switch 10 while dragging with a finger. If it is wider than 15 mm, it is not easy to operate. Excessive force is applied, causing a problem in which the skin material 7 is separated.

Now the operation of the present invention will be described.

In the non-use state as shown in FIGS. 2 and 4, the lifting module 40 is in a descending state, and the window switch 10 is spaced below the skin 7. The skin 7 is not stretched and does not transmit light, and the LED 6 has not yet been lit.

In the above state, when the user touches the window switch 10 through the skin 7 in a predetermined operation method (maintaining the touch state for more than a set time, double touch, etc.), the LED 6 is turned on by the control unit (not shown). It is lit, and the motor 90 is rotated in the direction of raising the lifting module 40.

Accordingly, the lead nut 42 rises along the rotation shaft 91 by a screw action due to the action of the rotation shaft 91 and the lead nut 42, so that the lifting module 40 rises upward.

When it rises to the height determined by the control logic previously input to the control unit, the window switch 10 properly pushes the skin 7 and rises as shown in FIG. 5.

Therefore, from the outside, the skin material 7 protrudes in the shape of a rod of the window switch 10, and the light of the LED 60 passes through the touch sensor 70, the window switch 10, and the stretched skin material 7 It is released to the outside so that the user's window switch 10 can be easily identified tactilely and visually.

In the above-described use state, the user can open and close the window glass by dragging the window switch 10 forward or backward with a finger.

On the other hand, the control unit can adjust the length of the light emitting unit displayed on the window switch 10 by adjusting the number of lights of the LED 60 according to the opening amount of the window glass (that is, the amount of operation of the driving motor of the window glass lifting device). .

Therefore, the user can guess the degree of opening of the window glass by looking at the length of the light emitting portion displayed on the window switch 10.

In addition, if the front end of the window switch 10 is touched with the set operation method, the control unit controls the motor to raise the window glass, regardless of the current opening amount (open state) of the window glass, and similarly sets the rear end. When touched in a manner, the control unit controls the motor to lower the window glass. Therefore, regardless of the current state of the window glass, the user can perform opening/closing control of the window glass as desired.

On the other hand, the morphing type power window switch device according to the present invention may further include a speaker and a vibration motor to generate different types of beeps and vibrations according to a position and method of operating the window switch 10. Accordingly, the driver can sense the operating state of the window switch 10 by hearing and tactile sense. At this time, the speaker may be a speaker already provided in the vehicle. In addition, it is preferable that the vibration motor is installed in the lifting module 40 so that the user feels the vibration directly at the switch manipulation (touch) position through a finger touching the window switch 10.

Therefore, the driver can determine the opening and closing state of the window glass through auditory and tactile auxiliary signals at the same time as well as directly seeing the amount of opening and closing of the window glass and the light emission state of the window switch 10 (length of the light emitting unit). It is possible to more intuitively and easily grasp the opening and closing state of, and it is possible to reliably know whether the window switch 10 is correctly operated as intended, so that the window opening and closing operation can be performed more easily.

On the other hand, when the window switch 10 is not used for a set time or the set time elapses after the vehicle engine is stopped and the door locking device is locked, the control unit controls the motor 90 to operate the lifting module 40. Descend. When the lifting module 40 descends and returns to its original position as shown in FIG. 4, the window switch 10 is separated from the lower side of the skin 7 so that the window switch 10 is located on the upper surface of the armrest 6 when viewed from the outside. The protruding shape of is not visible.

In addition, since the LED 60 is turned off and the skin 7 is restored to a contracted state, the light emitted from the window switch 10 to the outside disappears, so that the window switch 10 cannot be seen at all from the outside. The upper surface of the rest 6 only shows the skin 7 so that a new aesthetic feeling can be felt from the armrest 6 of a neat design without a conventional power window switch device.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is only exemplary, and various modifications and equivalent other embodiments are provided from those of ordinary skill in the field to which the technology pertains.
