Description

M264164 __ IV. Creation Instructions (1) [New Technology Field] This creation is related to the structural improvement of the screen display to strengthen its stability, and aims to provide a car screen structure that is particularly suitable for being installed in a car. [Previous technology ] Due to the popularization of electronic digital technology, the display generally used for displaying images has gradually been replaced by the liquid crystal display. Because the liquid crystal display has the characteristics of light body and low power consumption, it is no longer limited. It is used indoors in buildings and can be widely used in general vehicles. When the vehicle is in use, its passengers can cooperate with other audio-visual equipment, use the LCD display on the car to watch videos to pass the time, or use the reverse The monitor and other monitoring equipment are connected, so that the driver can be monitored at any time by the LCD monitor to monitor the dead angle around the vehicle to improve the safety of the vehicle. As shown in the first figure, it is a common car screen on the market. The screen display is installed in a liquid crystal box 7 1 which is connected to the slider 7 4 through the rotating shaft 7 2 and the flip gear 7 3. The reversing gear 7 3 is fixed on the liquid crystal box 7 1. The main motor 7 5 and the auxiliary motor 7 6 are installed in the slider 7 4. The driving gear 7 8 and the reversing gear 7 3 are driven by the respective reducers 7 7. When rotating, the slider 7 4 is mounted on the slider 7 4; when it is turned on, the liquid crystal cell 71 is powered on and the main motor 7 5 is rotated forward, so that the driving gear 7 8 which is engaged with the rack on the slide rail 7 4 drives the slide Block 7 4 push the LCD box 7 1 out of the panel.

Page 5 M264164 IV. Creation instructions (2) The auxiliary motor 7 6 rotates the reversing gear 7 3 and turns the liquid crystal box 7 1 upward by a certain angle to form the viewing angle as shown in the second figure. However, the LCD box 71 is installed in the car body, and it will shake when the car is walking. Therefore, when the driving gear 7 8 and the rack on the slide rail 7 4 are engaged and moved, it is often caused by the car body shaking. The racks on the driving gear 7 8 and the slide rail 7 4 are disengaged from each other or are offset, so that the slider 7 4 cannot smoothly push the LCD box 7 1 out of the panel, which may even cause the LCD screen to fail to open. [New content] This creation "Car screen linkage structure", which mainly has a shell seat that can be fitted with the box seat of the car body. The shell seat is provided with a track extending from the inside of the box seat toward the box seat opening. There is also a coupling seat in the shell seat, and the screen display is pivoted with the coupling seat, and there is a first driving component for driving the coupling seat to linearly move back and forth along the track, and the second driving The component drives the liquid crystal display to be folded at an appropriate angle. Among them, a guide rail is provided inside the housing base, and a side of the coupling base is provided with a guide block fitted with the guide rail. When the coupling base is in the housing base, When doing a linear movement back and forth along the track, at the same time, the guide block also moves linearly on the guide rail, which can ensure the stability of the movement of the coupling seat, and improve the poor adhesion of the conventional coupling seat when moving along the track, resulting in Deviations or departures from the way. [Implementation] In order to make your review committee aware of the composition of this creation, and

M264164 _ IV. Creation instructions (3) The overall operation mode is described below with drawings: The creation of the "vehicle screen linkage structure", the structure of the overall collapsing device is as shown in the second to fourth embodiments. The system includes: a shell seat 10, which is arranged in the box seat A of the vehicle for assembling audiovisual equipment, and at least one track 1 1 is fixed on the inside of the shell seat 10, and the track 11 is a rack And it extends from the inside of the cassette base toward the opening of the cassette base. A coupling base 20 is provided inside the housing base 10 for connecting the housing base 10 and the screen display L, and can linearly move back and forth along the track 11 in the housing base 10. A screen display L is provided with a pivot axis L 1 on both sides thereof. The pivot axis L 1 is connected to the coupling seat 20, and the pivot axis L 1 can be used as an axis to fold at an appropriate angle to facilitate folding to the layout. It is level with the box base, and the panel is folded to the angle most suitable for viewing. The first driving component 30 is provided inside the coupling seat 10 and has a main rotating shaft 3 1 which can be mutually driven with the track 11. The main rotating shaft 3 1 is provided with a rack which is matched with the rack of the track 1 1. The main rotating gear 3 1 1 is driven by the first motor 3 2 to rotate the main rotating shaft 3 1. A first reduction gear set 5 1 is provided between the first motor 3 2 and the main rotating shaft 31 to make the coupling seat 2 〇 A linear back-and-forth movement is performed in the shell base 10 along the orbit 11. The second driving component 40 is located inside the coupling seat 20, and has a transmission element 41 to facilitate the transmission effect between the display and the screen display L. The transmission element 41 is a follower fixed on the pivot L1. The gear is driven, and the second motor 4 2 drives the transmission element 41 to move. The second motor 4 2 and

M264164 IV. Creation instructions (4) A second reduction gear set 5 2 is provided between the transmission elements 41, and a coupling 5 3 is connected between the mandrel of the second and fourth motors 4 2 and the second reduction gear set 5 2 They are connected to make the screen display L perform an angle folding motion with the pivot L 1 as the axis. The key point of this case is that when referring to the fifth and sixth figures, a guide 6 1 is provided inside the housing seat 10, and the coupling seat 20 — side is provided with an insert with the guide rail 61. The combined guide block 62, when the screen display L is to be used, as shown in the fourth and seventh figures, the first driving component 30 drives the screen display L to move toward the outside of the box A, and at the same time the guide block 6 2 also moves linearly on the guide rail 6 1 to ensure the stability of the movement of the screen display L, and the main rotation gear 3 1 1 will not be disengaged from the rack of the track 1 1 due to the shaking of the car body, and extended on the screen display L After the box A, the second drive unit 40 turns the screen display L to the panel for the best viewing state, as shown in the second picture, for normal use. When the screen display is not in use, as shown in the fourth and fifth figures, the panel of the screen display L and the panel A can be folded to a state parallel to the box A by the second drive assembly 40, and One drive assembly 30 drives the coupling seat 20 and the screen display L to move toward the inside of the box A. Similarly, the guide block 6 2 and the guide rail 6 1 can ensure the stability of the movement of the screen display L, and the screen display L can be moved. L is hidden in the holder, as shown in the eighth figure, to protect the screen display L without causing obstruction. In another embodiment of this creation, as shown in the fifth and sixth figures, another track groove 6 3 is provided inside the housing base 10, and the holding groove 6 3 is shaped.

M264164 IV. Creation instructions (5) An opening 6 3 1 facing the inside of the shell seat 10, and the coupling seat 20 — side is provided with a guide wheel 6 4 that can extend into the holding groove 6 3. When the coupling seat 2 0 is When the linear movement of the back and forth along the track is performed in the shell library 10, the guide wheel 64 is also moved linearly in the track 6 3, which can ensure the stability of the movement of the coupling seat 20 and improve the conventional coupling seat. Poor adhesion when moving along the road, causing the situation to shift or off track.
