However, their size and dimensions place significant demands on installation space, particularly in the limited space of vehicle and airborne cockpits. Therefore, there is an urgent need for a retractable device that can accommodate LCD modules while effectively saving space within the cabin.

[0003] Therefore, there is an urgent need to provide a retractable display device to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a retractable display device that can both accommodate the installation of a liquid crystal display module and effectively save interior space.

[0005] To achieve the above objectives, the present invention provides a retractable display device, which includes two track assemblies arranged opposite to each other, a mounting plate fixedly connected to the upper ends of the two track assemblies, a connecting assembly movably connected to the two track assemblies respectively, and a display module fixedly connected between the connecting assemblies on both sides. The display module can be pushed forward along the track assemblies for storage or pulled backward for use.

[0006] Preferably, the track assembly includes a track plate and a slide rail disposed on the track plate. The slide rail includes a horizontal section at the front that allows the connecting assembly to slide linearly and an inclined section at the rear that allows the connecting assembly to tilt downward.

[0007] Preferably, the slide rail includes an upper rail, a lower rail, and a bridging rail connecting the rear section of the upper rail and the rear section of the lower rail. The lower rail is a straight rail, the front side of the upper rail is a straight rail parallel to the lower rail, and the rear section of the upper rail is a curved rail centered on the rear end of the lower rail and tangent to the straight section of the upper rail. The bridging rail is also configured as a curved rail centered on the rear end of the lower rail.

[0008] Preferably, the slide rail is a grooved slide rail that runs through the track plate.

[0009] Preferably, the groove of the slide rail is a stepped groove, and the two track plates are arranged opposite each other on the side with the smaller width of the stepped groove.

[0010] Preferably, a sealing plate for sealing the side with the larger width of the stepped groove is fixedly installed on one side of the two track plates facing away from each other.

[0011] Preferably, the connecting assembly includes a connecting plate and a set of rollers connected to the front side of the connecting plate and cooperating with the track assembly.

[0031] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] This invention provides a retractable display device, such as... Figures 1-4 As shown, the retractable display device includes two track components 1 arranged opposite to each other, a mounting plate 2 fixedly connected to the upper end of the two track components 1, a connecting component 3 movably connected to the two track components 1 respectively, and a display module 4 fixedly connected between the connecting components 3 on both sides, so that the connecting component 3 can move back and forth relative to the track components 1, and the display module 4 can be pushed forward along the track components 1 for storage or pulled backward for use.

[0033] When the display module 4 is needed, pull the display module 4 backward. The display module 4 will then slide backward together with the connecting component 3 that is fixedly connected to it, until the display module 4 leaves the storage space formed by the track component 1 and the mounting plate 2.

[0034] When the display module 4 is not in use, it will be pushed forward and slide together with the connecting component 3 into the storage space formed by the track component 1 and the mounting plate 2. This retractable display device can both meet the installation requirements of the liquid crystal display module 4 and effectively save space inside the cabin.

[0035] In this embodiment, such as Figures 5-6 As shown, the track assembly 1 includes a track plate 5 and a slide rail disposed on the track plate 5. The slide rail includes a horizontal section at the front that allows the connecting assembly 3 to slide linearly and an inclined section at the rear that allows the connecting assembly 3 to tilt downward.

[0036] The upper end of the track plate 5 is provided with multiple connection holes, and the mounting plate 2 is also provided with connection holes at the corresponding positions. The mounting plate 2 is fixedly connected to the upper end of the two track plates 5 by screws.

[0037] In actual use, after the display module 4 is pulled out, the connecting component 3 can be slid down to the rear of the slide rail and rotate downwards when it is tilted, so that the display module 4 can be tilted at a certain angle to face the face, preferably between 15° and 45°, which can greatly improve the comfort of using the display module 4.

[0038] When storing the display module 4, first rotate the display module 4 to a horizontal position, and then push it forward so that the connecting component 3 enters the horizontal part. Continue to push it forward, and the display module 4 slides straight forward into the storage space. The connecting component 3 and the slide rail can be set to a damping fit to prevent the display module 4 from sliding backward when it is in the storage state. Alternatively, the position of the connecting component 3 can be fixed by other positioning structures to achieve the purpose of fixing the display module 4.

[0039] In this embodiment, such as Figures 6-10 As shown, the slide rail includes an upper rail 6, a lower rail 7, and a bridging rail 8 connecting the rear section of the upper rail 6 and the rear section of the lower rail 7. The lower rail 7 is a straight rail, the front side of the upper rail 6 is a straight rail parallel to the lower rail 7, and the rear section of the upper rail 6 is a curved rail centered on the rear end of the lower rail 7 and tangent to the straight section of the upper rail 6. The bridging rail 8 is also a curved rail centered on the rear end of the lower rail 7.

[0040] The connecting assembly 3 includes a connecting plate 10 and a set of rollers connected to the front side of the connecting plate 10 and cooperating with the track assembly 1.

[0041] The connecting plate 10 is provided with multiple mounting holes, which should be countersunk holes. The display module 4 is fixed to the connecting plate 10 by screws, and the screw heads do not protrude from the connecting plate 10 so that the connecting plate 10 can fit with the track plate 5.

[0042] The roller assembly includes three rollers 11, which are located at the three corners of a right triangle. The roller 11 at the right angle is located on the back side of the right triangle and inside the lower track 7, and the distance between any two rollers 11 on any right angle side is equal to the radius of the curved track.

[0043] The specific cooperation between the roller 11 and the slide rail is as follows: when the display module 4 is in the storage state, the two rollers 11 at the bottom are in the lower track 7, and the roller 11 at the top is in the upper track 6. Due to the interaction between the roller 11 and the track, the connecting plate 10 and the display module 4 cannot rotate and remain parallel to the track assembly 1.

[0044] When display module 4 is needed, it is pulled out backward, causing the connecting plate 10 to move backward as well. At this time, the three rollers 11 slide backward within the slide rails. When the roller 11 at the right angle moves to the rear end of the lower track 7, another roller 11 within the lower track 7 is located at the intersection of the bridging track 8 and the lower track 7, while the upper roller 11 is located at the intersection of the curved and straight rails of the upper track 6. Then, the display module 4 is rotated downward around the roller 11 at the right angle. The two rollers 11 at 45° angles slide along the curved rail until one of them reaches the rear end of the curved rail. Constrained by the rollers 11 and the rails, the tilted display module 4 has only one degree of freedom to rotate upward around the roller 11 at the right angle. However, due to gravity, the display module 4 can maintain its tilted state and remain stationary. To store the display module 4, simply reverse the above steps.

[0045] In this embodiment, the slide rail is a grooved slide rail that runs through the track plate 5, so that there are no protrusions on the inner side of the track plate 5, and the connecting plate 10 can be basically fitted with the track plate 5, which can enhance the constraint on the connecting plate 10 in the left and right directions. At the same time, compared with adding a track on the inner side of the track plate 5, the grooved slide rail has a higher structural strength because it takes the track plate 5 as its outline.

[0046] In this embodiment, the slide rail has a stepped groove with two layers of holes. The two track plates 5 are positioned opposite each other with the narrower side of the stepped groove, meaning the narrower side is located inside the track plate 5 and the wider side is located outside the track plate 5.

[0047] In this embodiment, the roller 11 is configured as a stepped shape that fits into the grooved slide rail, and the smaller diameter end of the roller 11 is inserted into the connecting plate 10. The stepped roller 11 and the stepped grooved slide rail can prevent the roller 11 from moving inward to the track plate 5 and can also prevent the roller 11 from deflecting.

[0048] In this embodiment, a sealing plate 9 is fixedly installed on one side of the two track plates 5 facing away from each other to close off the side with the wider stepped groove. The sealing plate 9 can restrain the roller 11 from moving outward from the track plate 5, so that the roller 11 can only move along the slide rail path. The four corners of the sealing plate 9 and the four corners of the track plate 5 are provided with connecting holes, and the sealing plate 9 is fixedly connected to the track plate 5 by screws.

[0049] In this embodiment, such as Figure 7 , Figure 11 As shown, a groove 12 is provided on the upper front side of the connecting plate 10, and a screw 13 that fits into the groove 12 is threaded onto the rear side of the track plate 5 to restrict the upward rotation of the pulled-out connecting plate 10. When the display module 4 is in an inclined state, the screw 13 can be connected to the threaded hole on the track plate 5. The sealing plate 9 is also provided with a corresponding through hole, so that the screw 13 can be inserted into the groove 12 on the upper front side of the connecting plate 10. At this time, the connecting plate 10 cannot rotate upward, thereby completely fixing the display module 4.

[0050] When it is necessary to store the display module 4, rotate the screw 13 to disengage it from the groove 12, thereby releasing the constraint on the connecting plate 10 and allowing the display module 4 to be stored. After storage, the screw 13 can be rotated again to clamp the connecting plate 10, or a corresponding hole can be provided on the side of the display module 4, allowing the screw 13 to be inserted into the hole to fix the display module 4 in the storage space.

However, the present invention is not limited to the specific details of the above embodiments.
