Description

Technical Field

[0001] This utility model relates to the field of display device technology, and more specifically, to a storage and unfolding device and display device for folding devices. Background Technology

[0002] With the gradual development of foldable display technology, foldable screens are increasingly entering people's daily lives. The ease of storage of foldable displays offers new ideas for existing device storage solutions. For example, the main screen in current vehicles is placed directly between the driver and passenger seats, making storage impossible and affecting the aesthetics of the car interior. Furthermore, in vehicles and airplanes, entertainment in-seat displays are mostly folded overhead, negatively impacting passenger viewing. Placing the screen behind the seat, on the other hand, occupies passenger space and causes inconvenience when getting in and out of the seat. Summary of the Invention

[0003] This invention overcomes the shortcomings of existing display devices in terms of inconvenient storage, and provides a storage and unfolding device and display device for folding devices, in order to solve the problem of inconvenient storage in the prior art.

[0004] To address the aforementioned technical problems, one aspect of this utility model provides a storage and unfolding device for folding equipment:

[0005] A storage and unfolding device for folding equipment includes: an unfolding device, a sliding guide rail, and a pushing device;

[0006] The unfolding device includes an unfolding plate, a hinge, and a slider. The unfolding plate includes an upper plate and a lower plate, which are hinged together. A slider is provided on the back side of the upper plate and the lower plate, and the slider can move along a sliding guide rail.

[0007] The sliding guide rail includes an upper guide rail and a lower guide rail. The upper guide rail and the lower guide rail include a horizontal section and a bent section. The bent section is located in the pushing direction of the unfolding plate. The track of the upper guide rail bends upward with the bent section, and the track of the lower guide rail bends downward with the bent section.

[0008] The pushing device is configured to push the unfolding device forward and backward under the guidance of the sliding guide rail. During the movement of the unfolding plate, the slider moves with the direction of the guide rail, and the slider drives the upper plate and the lower plate to unfold and fold.

[0009] The key feature of this invention is that it utilizes the small storage space of folding screens to fold and store them within a designated storage space, such as the car's center console or the interior of the front seats. When folded, the lateral dimensions of the folding display are significantly reduced, and it does not occupy external space when not in use. When needed, a pushing device moves the unfolding device, which moves outward and unfolds under the guidance of a sliding rail. To fold and store the screen, the pushing device pulls the unfolding device backward.

[0010] The slider in this application is located on the back side of the upper and lower plates of the unfolding device. Its turning radius is small, and the length and curvature of the guide rail that it cooperates with can also be small, reducing space occupation.

[0011] A further technical solution is that the number of upper guide rails and lower guide rails is two or more;

[0012] The number and position of the sliders are matched with the number and position of the corresponding upper and lower guide rails.

[0013] Increasing the number of guide rails and sliders can improve stability during movement and reduce swaying.

[0014] A further technical solution also includes a mounting base plate and a slide rail mounting bracket;

[0015] The slide rail mounting bracket is mounted on the mounting base plate, and the upper guide rail and lower guide rail are mounted on the slide rail mounting bracket.

[0016] A further technical solution is that the upper and lower guide rails are configured to move controllably relative to the slide rail mounting bracket.

[0017] The unfolding action of the unfolding device is actually affected by the guide rail trajectory and the relative position of the guide rail. When the guide rail trajectory is symmetrical, the unfolding angles of the upper and lower plates are also synchronized. This method is suitable for the unfolding of the display screen. However, if it is necessary to control the unfolding angle, the front and rear positions of the guide rail can be adjusted to achieve an asymmetrical setting of the guide rail trajectory, thereby realizing the unfolding angle control of the unfolding device.

[0018] A further technical solution is that the pushing device includes a first motor, a first gear, a first rack, and a pushing rod;

[0019] The first gear is mounted on the first motor shaft, and the first rack is mounted on the push rod. The first gear meshes with the first rack.

[0020] A further technical solution is that the propulsion device also includes a thrust buffer device;

[0021] The thrust buffer device is connected to the deployment device and the push rod at both ends, and the two ends connecting the thrust buffer device to the deployment device and the push rod are movably connected.

[0022] A further technical solution is that the storage and unfolding device also includes a movable baffle;

[0023] The movable baffle includes a front baffle, a movable baffle, and a baffle driving device;

[0024] The front baffle is provided with an opening, which allows the unfolding device to pass through when it moves forward and backward.

[0025] The movable baffle is located behind the opening of the front baffle, and the movable baffle is configured to completely cover the opening.

[0026] The movable baffle is connected to a baffle driving device, which is configured to drive the movable baffle to move so that the movable baffle no longer blocks the opening.

[0027] A further technical solution is that the baffle driving device adopts one of the following schemes;

[0028] Option 1: The baffle driving device includes a baffle driving motor, a second gear, a second rack, and a baffle connecting plate;

[0029] The second gear is mounted on the shaft of the baffle drive motor, the baffle connecting plate is mounted on the movable baffle, the second rack is mounted on the baffle connecting plate, and the second gear meshes with the second rack;

[0030] Option 2: The baffle driving device includes a transmission gear set, a second rack, and a baffle connecting plate;

[0031] The baffle connecting plate is mounted on the movable baffle, and the second rack is mounted on the baffle connecting plate. The transmission gear set is configured to realize the transmission from the pushing device to the second rack.

[0032] A further technical solution is that the baffle driving device also includes a baffle pressing device;

[0033] The baffle pressing device presses the movable baffle onto the front baffle.

[0034] The main purpose of pressing the movable baffle against the front baffle is to prevent the movable baffle from shaking, thereby reducing the noise generated by the shaking of the entire equipment.

[0035] In another aspect, this utility model also provides a display device.

[0036] A display device includes a foldable display screen and a storage and unfolding device as described above;

[0037] The upper half of the folding display screen is located on the inner side of the upper plate of the unfolding plate, and the lower half of the folding display screen is located on the inner side of the lower plate of the unfolding plate. The folding display screen unfolds and folds as the upper and lower plates move.

[0038] Compared with existing technologies, this invention has at least the following advantages: Firstly, it utilizes the small storage space of folding screens, storing them within a designated space, such as the car's center console or the interior of the front seats. After folding, the lateral dimensions of the folding display are significantly reduced, and it does not occupy external space when not in use. When needed, a pushing device moves the unfolding device, which moves outward and unfolds under the guidance of a sliding rail. During folding, the pushing device drags the unfolding device backward, achieving folding and storage. Furthermore, this invention places sliders on the back of the upper and lower plates of the unfolding device, resulting in a smaller turning radius and correspondingly smaller length and curvature of the guide rails, further reducing space occupation.

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] Example 1

[0049] A storage and unfolding device 1 for folding devices, see [reference] Figure 1 , Figure 2 Includes: unfolding device 1, sliding guide rail 2, and pushing device 3;

[0050] The structure of the unfolding device 1 is shown in the figure. Figure 3 , Figure 4 The system includes an unfolding plate 11, a hinge 12, and a slider 13. The unfolding plate 11 includes an upper plate 111 and a lower plate 112, which are hinged together by the hinge 12. A slider 13 is provided on the back side of the upper plate 111 and the lower plate 112. The slider 13 can move along the sliding guide rail 2. In this embodiment, the slider 13 is locked in the sliding guide rail 2.

[0051] The sliding guide rail 2 includes an upper guide rail 21 and a lower guide rail 22. The upper guide rail 21 is disposed above the upper plate 111, and the lower guide rail 22 is disposed below the lower plate 112. The upper guide rail 21 and the lower guide rail 22 include a horizontal section and a bent section. The bent section is disposed in the pushing direction of the unfolding plate 11. The track of the upper guide rail 21 bends upward with the bent section, and the track of the lower guide rail 22 bends downward with the bent section.

[0052] It is understandable that the bend can be an arc or a straight line with a certain angle.

[0053] In a preferred embodiment, there are two or more upper guide rails 21 and lower guide rails 22;

[0054] The number and position of the sliders 13 match the number and position of the corresponding upper guide rails 21 and lower guide rails 22.

[0055] The guide rail can be a slide rail with grooves on both sides, or it can be a hollow slide rail. Specifically, in this embodiment, the guide rail is a slide rail with grooves on both sides, and there are two upper guide rails 21 and two lower guide rails 22.

[0056] The pushing device 3 is configured to push the unfolding device 1 to move forward and backward under the guidance of the sliding guide rail 2. During the movement of the unfolding plate 11, the slider 13 moves with the direction of the guide rail, and the slider 13 drives the upper plate 111 and the lower plate 112 to unfold and fold.

[0057] Figure 2 The direction of the middle arrow indicates the direction of movement of the pushing device 3.

[0058] In this embodiment, the storage and unfolding device 1 also includes a mounting base plate 4 and a slide rail mounting bracket 5, see [link to documentation]. Figure 5 ;

[0059] The slide rail mounting bracket 5 is mounted on the mounting base plate 4. The upper guide rail 21 and the lower guide rail 22 are mounted on the slide rail mounting bracket 5. The mounting bracket is C-shaped and slide rails can be mounted on its upper and lower sides.

[0060] In a further preferred embodiment, the upper guide rail 21 and the lower guide rail 22 are configured to move controllably relative to the slide rail mounting bracket 5.

[0061] It is understood that the unfolding action of the unfolding device 1 is determined by the guide rail trajectory and the relative position of the guide rail. In the embodiment shown in the attached figure, the guide rail trajectory is a combination of straight lines and arcs, and the shape is symmetrical.

[0062] In this case, the unfolding angles of the upper plate 111 and the lower plate 112 are synchronized, and the pushing position of the pushing device 3 determines the position of the slider 13 relative to the guide rail, which in turn determines the unfolding angles of the upper plate 111 and the lower plate 112. This method is suitable for unfolding display screens.

[0063] However, in actual use cases, there may be situations where the upper and lower plates 112 need to be unfolded at different angles. When the track trajectory is not easy to change, the front and rear positions of the guide rail can be adjusted to achieve an asymmetrical setting of the guide rail trajectory, thereby controlling the unfolding angle of the unfolding device 1.

[0064] For example, a track and a driving device can be set between the upper guide rail 21, the lower guide rail 22 and the corresponding slide rail mounting bracket 5. The driving device can be any of the following: a combination of lead screw and nut, a combination of rack and pinion, an electric cylinder, hydraulic transmission, etc.

[0065] The pushing device 3 can be any of the following: a combination of rack and pinion, an electric cylinder, or a hydraulic transmission.

[0066] For example, see Figure 6 In this embodiment, the pushing device 3 includes a first motor 31, a first gear 32, a first rack 33, a pushing rod 34, and a thrust buffer device 35;

[0067] The first gear 32 is mounted on the shaft of the first motor 31, and the first rack 33 is mounted on the push rod 34. The first gear 32 meshes with the first rack 33.

[0068] The two ends of the thrust buffer device 35 are connected to the deployment device 1 and the push rod 34 respectively, and the two ends of the thrust buffer device 35 connected to the deployment device 1 and the push rod 34 are movably connected.

[0069] In this embodiment, the thrust buffer device 35 is slidably mounted on the push rod 34, and its two ends are connected to the unfolding device 1 and the push rod 34 respectively by screws. During the pushing process, the thrust is transmitted from the push rod 34 to the thrust buffer device 35 and then to the unfolding device 1, avoiding uneven force caused by errors in the thrust of the push rod 34 and the direction of the slide rail.

[0070] In a preferred embodiment, the storage and unfolding device 1 further includes a movable baffle 626;

[0071] The movable baffle 626 includes a front baffle 61, a movable baffle 62, and a baffle driving device 63;

[0072] The front baffle 61 is provided with an opening, and the unfolding device 1 can pass through the opening of the front baffle 61 when it moves forward and backward.

[0073] The movable baffle 62 is disposed on the rear side of the opening of the front baffle 61, and the movable baffle 62 is configured to completely cover the opening.

[0074] The movable baffle 62 is connected to the baffle driving device 63, which is configured to drive the movable baffle 62 to move so that the movable baffle 62 no longer blocks the opening.

[0075] To improve safety during use, the telescopic opening needs to be sealed when the unfolding device 1 is not needed.

[0076] Specifically, the baffle driving device 63 can adopt one of the following schemes;

[0077] Option 1: The baffle driving device 63 includes a baffle driving motor 631, a second gear 632, a second rack 633, and a baffle connecting plate 634.

[0078] The second gear 632 is mounted on the shaft of the baffle drive motor 631, the baffle connecting plate 634 is mounted on the movable baffle 62, the second rack 633 is mounted on the baffle connecting plate 634, and the second gear 632 meshes with the second rack 633;

[0079] Since the baffle needs to open before the storage and unfolding device 1 extends, the effect of opening the baffle first and then extending the storage and unfolding device 1 can be achieved by adjusting the length of the push screw and adjusting the gear ratio.

[0080] In this embodiment, the baffle driving device 63 adopts Scheme 2.

[0081] Option 2: The baffle driving device 63 transmits a gear set, a second rack 633, and a baffle connecting plate 634;

[0082] The baffle connecting plate 634 is mounted on the movable baffle 62, and the second rack 633 is mounted on the baffle connecting plate 634. The transmission gear set is configured to realize the transmission from the pushing device 3 to the second rack 633.

[0083] In a further preferred embodiment, the baffle driving device 63 further includes a baffle pressing device 635;

[0084] The baffle pressing device 635 presses the movable baffle 62 onto the front baffle 61.

[0085] Pressing the movable baffle 62 onto the front baffle 61 is also to avoid unnecessary shaking of the entire device during movement.

[0086] It is understood that, since this embodiment can enable the upper plate 111 and the lower plate 112 to unfold at different angles, the storage and unfolding device 1 of this embodiment is not limited to use on folding screens, but can also be applied to any device that needs to be unfolded.

[0087] The hinge 12 design of the folding device can refer to the hinge 12 design of a laptop or the hinge 12 design of a folding phone. As long as the hinge 12 used can be unfolded at different angles, it is acceptable. Preferably, the hinge 12 can have a certain damping to achieve self-holding of the unfolding angle. Since the relevant technology of the hinge 12 is a mature existing technology, it will not be described in detail here.

[0088] When in use, after receiving the unfolding signal, the baffle drive device 63 works in conjunction with the movable baffle 626 to drive the movable baffle 62 to move, so that the movable baffle 62 no longer blocks the opening.

[0089] During or after this process, the first motor 31 of the pushing device 3 drives the first gear 32 to rotate, which in turn drives the first rack 33 to move, and the pushing rod 34 pushes the unfolding plate 11 to move.

[0090] Guided by the track, the upper plate 111 and lower plate 112 of the unfolding plate 11 first move outward along the straight track, and then open along the arc track trajectory, thus unfolding the unfolding plate 11. (See [reference]) Figure 7 .

[0091] The folding and recycling steps are the reverse of the steps described above.

[0092] Example 2

[0093] A display device includes a folding display screen and a storage and unfolding device 1 as described above;

[0094] The upper half of the folding display screen is located inside the upper plate 111 of the unfolding plate 11, and the lower half of the folding display screen is located inside the lower plate 112 of the unfolding plate 11. The folding display screen unfolds and folds as the upper plate 111 and the lower plate 112 move.

[0095] Although the invention has been described herein with reference to illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of this disclosure. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
