BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display drive device, and more particularly, to a display drive device for inclining a display panel mounted on an automobile to display an image or the like.

Recently, display apparatuses with LCDs have been miniaturized and mounted on dashboards of automobiles.

1 is a perspective view briefly illustrating an operation of sliding a display panel in a conventional sliding display device, and FIG. 2 is a side cross-sectional view illustrating a schematic configuration of the display device of FIG. 1.

As shown in Fig. 1, the display panel 1 mounts the LCD as large as possible within the installation area of the dashboard 2 as much as possible.

Since the LCD is thin compared to the display area of the screen, the audio device 3 is provided around the display panel 1 in order to effectively use the space in the limited dashboard 2.

1 (a) is when the display panel 1 is not used, (b) is when the display panel 1 is used, (c) shows the state when using the audio device 3, respectively. have.

When the display panel 1 is not used, as shown in FIG. 1 (a), the display panel 1 is accommodated in a predetermined position so that the display panel 1 does not protrude from the dashboard 2 as shown in FIG. It is preventing danger.

When the display panel 1 is used, as shown in FIG. 2 (b), the display panel 1 is slid so as to protrude obliquely, so that the driver or the passenger can easily see it.

Such movement of the display panel 1 before and after is performed by the configuration as shown in FIG.

The display panel 1 is provided on the front side of the main body chassis 4 and slides as shown in FIG. 1 by the slider 5 movable in the front-rear direction.

A guide groove 6 is formed in the slider 5 along its front and rear direction in a longitudinal direction, and a guide shaft 7 fixed to the main body chassis 4 is inserted into the guide groove 6.

Since the two guide shafts 7 are fitted in the guide grooves 6 at regular intervals, the slider 5 is guided back and forth by the guide shaft 7 to be movable.

The tip of the slider 5 is connected to the lower end of the display panel 1 by the pin coupling portion 8.

A guide groove 10 is formed in the front panel 9 of the main body chassis 4, and is inserted into the guide shaft 11 near the upper end of the display panel 1.

The rack 12 is formed in the upper part of the base end side of the slider 5, and is rotated by the rotation drive force transmitted using the gears 15, 16, and 17 from the worm gear 14 provided in the rotating shaft of the motor 13. The slider 5 is driven in the front-rear direction.

A clutch 19 is provided between the gear 15 and the gear 16 so that excessive driving force is transmitted from the motor 13 to the slider 5, and excessive load from the slider 5 is applied to the motor 13. To prevent it from being delivered to.

However, such a conventional display driving apparatus has a display panel 1 when the slider 5 is slid in the front and rear directions when a product has a tolerance between the guide groove 6 and the guide shaft 7. There is a problem that flows left and right.

In order to solve this problem, Japanese Patent Laid-Open No. 10-51712 has a structure as shown in FIG.

3 is a perspective view and a cross-sectional view schematically showing a schematic configuration of a conventional display driving apparatus.

As shown in FIG. 3, a corro 82 is mounted on an upper portion of the rotating shaft 81 installed on the bottom surface of the main chassis 24.

In the core 82, a tapered portion 83 having an enlarged outer diameter is formed, and elastically supported upward by the spring 84.

The long hole 86 is formed in the slider 85 along the front-back direction, and the width | variety of the long hole 86 is slightly larger than the minimum diameter of the taper part 83 of the corro | 82.

When the core 82 is inserted into the long hole 86 from below, the slider 85 generates friction at the contact portion between the long hole 86 and the taper portion 83 of the core 82, thereby causing the slider 85 to be moved. Shaking in the width direction can be prevented.

However, such a conventional display driving apparatus has a complicated structure for preventing the slider from flowing in the up, down, left, and right directions, thereby degrading assembly and productivity, and increasing the number of parts, thereby increasing the cost. There is this.

In addition, since the corro 82 is jumped at regular intervals, the contact area between the corro 82 and the long hole 86 is short, and thus the oscillation generated when the slider 85 moves forward and backward cannot be completely eliminated. .

The present invention has been made to solve the above-described problems, to provide a display driving device that can prevent the phenomenon that the slider flows in the up, down, left, right direction by using a small number of parts and a simple structure. The purpose is.

In order to achieve the above object, the present invention provides a display drive device which is mounted and driven so that the display panel is slidably inclined forward in the main chassis, the guide members mounted on both sides of the main chassis; A slider mounted to the front and sliding forward and backward along the guide member; A slider configured to drive the slider, wherein the slider comprises: a first slider driven by the driver to slide forward and backward; A second slider sliding forward and backward by the first slider, the main chassis being gear-coupled with the first slider and the second slider to transfer the moving force of the first slider to the second slider It provides a display driving device formed with a transmission.

Gears are formed on upper surfaces of the first slider and the second slider, and the power transmission unit is rotatably mounted to the main body chassis in a shaft shape having gears on both sides thereof.

Sliding grooves are formed long in the front and rear on either side of either the guide member or the slider, and upper slide pieces inserted into the sliding grooves are formed on the upper sides of the other one of the guide member or the slider. A lower left and right flow prevention part is formed in the lower part of the member, and a lower slide piece is formed in the lower part of the slider which contacts the left and right flow prevention part in a left and right direction.

The sliding groove surrounds the upper and lower parts of the upper slide piece, and the left and right flow preventing parts make surface contact with the left or right side of the lower slide piece.

The first slider and the second slider are formed with a bending piece that is bent downward and supported by the guide member.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

4 is a one-way perspective view of the display driving apparatus according to the present invention, FIG. 5 is another perspective view of the display driving apparatus according to the present invention, FIG. 6 is an exploded perspective view of the display driving apparatus according to the present invention, and FIG. 8 is a perspective view of the slider according to the present invention, and FIG. 8 is a cross-sectional view taken along line AA of FIG. 4, and FIG. 9 is an overall structural diagram of a display driving apparatus according to the present invention.

The display driving apparatus of the present invention includes a main chassis 110, guide members 120 and 130, sliders 140 and 150, a power transmission unit 112, and a driving unit 160.

The main chassis 110 is made of a flat plate, and is bent upwardly so that the guide members 120 and 130 may be mounted on both side surfaces thereof.

The guide members 120 and 130 are mounted on both sides of the main chassis 110 to guide the movement of the sliders 140 and 150 in the front and rear directions, and are mounted on the left side of the main chassis 110. It consists of a guide member 120 and the second guide member 130 mounted on the right side.

Sliding grooves 121 and 131 are elongated in the front and rear of the first guide member 120 and the second guide member 130, respectively.

In this case, the sliding grooves 121 and 131 are formed in a '⊂' or '⊃' shape in which the left or right side is opened.

The sliders 140 and 150 slide forward and backward along the first guide member 120 and the second guide member 130. The sliders 140 and 150 are formed of the first slider 140 and the second slider 150. As shown in FIG. 12, the display panel 170 is mounted.

The first slider 140 is shown in FIG. 7 (a) and the second slider 150 is shown in FIG. 7 (b).

The first slider 140 is mounted in the direction of the first guide member 120 and is driven in the front-rear direction by the driving unit 160, and the second slider 150 is directed in the direction of the second guide member 130. It is mounted on the first slider 140 and the power transmission unit 112 is slid in the forward and backward direction.

Upper slide pieces 141 and 151 inserted into the sliding grooves 121 and 131 are bent to the left and right sides of the upper side of the first slider 140 and the second slider 150, respectively.

That is, as illustrated in FIG. 8, the upper slide pieces 141 and 151 are surrounded by the sliding grooves 121 and 131 so that the upper, lower and side surfaces thereof are covered with the sliding grooves 121 and 131 when the sliders 140 and 150 move forward and backward. ) Can be slid without shaking in the up, down, left and right directions.

In this case, the upper slide pieces 141 and 151 may be formed integrally with the first slider 140 and the second slider 150, but may be formed separately as shown in FIG. 6.

In addition, sliding grooves 121 and 131 are formed in the first slider 140 and the second slider 150, and upper slide pieces 141 and 151 are formed in the first guide member 120 and the second guide member 130. It may be formed.

In addition, left and right flow preventing portions 122 and 132 are formed at the lower portions of the first guide member 120 and the second guide member 130, respectively.

The left and right flow preventing parts 122 and 132 may be formed in a stepped shape, or may be formed by forming a groove as in the present embodiment.

Lower slide pieces 147 and 157 in contact with the left and right flow preventing portions 122 and 132 are bent and formed at the lower portions of the first slider 140 and the second slider 150, respectively. have.

In this case, the left and right flow preventing parts 122 and 132 and the lower slide pieces 147 and 157 are in surface contact with each other.

Thus, when the first slider 140 and the second slider 150 slide in the front-rear direction, the lower slide pieces 147 and 157 and the left and right flow preventing parts 122 and 132 are in surface contact with each other. The first slider 140 and the second slider 150 may be further prevented from shaking in the left and right directions.

In addition, since the left and right flow preventing parts 122 and 132 and the lower slide pieces 147 and 157 are both long, surface contact is performed in a large area, thereby further preventing left and right flow of the first slider 140 and the second slider 150. can do.

The first slider 140 and the second slider 150 are formed with bent pieces 143 and 153 bent downward, and the bent pieces 143 and 153 are formed of the first guide member 120 and the second guide member. Since it is in contact with the 130, the first slider 140 and the second slider 150 are elastically supported upward by the first guide member 120 and the second guide member 130.

That is, the bending pieces 143 and 153 serve as leaf springs that apply a force to compress the first slider 140 and the second slider 150 upward.

As described above, a force is applied to the first slider 140 and the second slider 150 to move upward by the elastic force of the bent pieces 143 and 153, and thus the upper slide pieces 141 and 151 are slid. Intense surface contact with the upper portions of the grooves 121 and 131 prevents the sliders 140 and 150 from flowing upward and downward.

The drive unit 160 is used to drive the sliders 140 and 150 and is mounted to the main chassis 110 so as to contact the first slider 140.

As in the prior art, the driving unit 160 includes a motor 161, a gear 162, and the like, and side slider gears 146 meshing with the gears 113 are formed on the sliders 140 and 150.

The power transmission unit 112 transmits the moving force of the first slider 140 to the second slider 150, and has a shaft shape, and gears 113 are formed on both sides of the main chassis ( 110 is rotatably mounted by a fixing part.

In addition, upper rack gears 148 and 158 are formed on the upper surfaces of the first slider 140 and the second slider 150, respectively, and mesh with the gears 113 formed on both sides of the power transmission unit 112.

Below, it looks at the operation of the present invention made of the above configuration.

When the driving unit 160 engaged with the side rack gear 146 of the first slider 140 is operated, the first slider 140 is moved forward and backward by the side rack gear 146. .

As the first slider 140 moves in the front-rear direction, the power transmission unit 112 is rotated by the upper rack gear 148 formed on the upper side of the first slider 140, which in turn is the second slider ( The first slider 140 is transferred to the upper rack gear 158 formed on the upper portion of the 150, so that the second slider 150 moves forward and backward together with the first slider 140.

In this case, since the driving unit 160 is in contact with the first slider 140 to generate a driving force, the first slider 140 and the second slider 150 generate a force to rotate in the left and right directions.

However, since the left and right flow preventing parts 122 and 132 and the lower slide pieces 147 and 157 are in surface contact in the left and right direction, the first slider 140 and the second slider 150 are not rotated in the left and right directions. Can be slid.

In addition, since the power transmission unit 112 is fixed to the main chassis 110 by the fixing unit, the rotational force is canceled by the fixing unit to the power transmission unit 112, so that the first slider 140 and the first unit are fixed. The two sliders 150 may be slid forward and backward without being rotated in the left and right directions.

In addition, the first slider 140 and the second slider 150 are elastically supported in the upward direction by the bent pieces 143 and 153 so that the upper slide pieces 141 and 151 face strongly with the upper portions of the sliding grooves 121 and 131. In this case, the first slider 140 and the second slider 150 may be prevented from shaking up and down.

The display driving apparatus of the present invention is not limited to the above-described embodiment, and may be variously modified and implemented within the scope of the technical idea of the present invention.

According to the display driving apparatus of the present invention as described above has the following advantages.

By using a small number of parts and a simple structure, the slider can be prevented from flowing in the up, down, left, and right directions, thereby improving assembly performance and productivity and reducing material costs.

In addition, since the slider and the guide member make a surface contact, the contact area is large, thereby completely eliminating the phenomenon of shaking during the forward and backward movement of the slider.

In addition, since the transfer force of the first slider is transmitted to the second slider by the power transmission unit fixed to the main chassis, the first slider and the second slider are rotated in the horizontal direction by the driving force of the driving unit mounted in one direction. Can be further prevented.
