Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of LED display screens, and particularly relates to a foldable LED display screen. Background Technique
[0002] An LED display screen is a flat panel display composed of small LED module panels, which is a device used to display various information such as text, images, and videos. The LED electronic display screen integrates microelectronics technology, computer technology, and information processing, and has the advantages of bright colors, wide dynamic range, high brightness, long service life, stable and reliable operation, etc.
[0003] Although the existing foldable LED display screens can be folded, most of them require the user to fold the display screen with both hands, and most of their bases need to be disassembled additionally, or need to be folded separately. The detachable base may require a screwdriver to remove the screws and then disassemble the base, while the separate folding of the base increases the operation steps. The operations of both types of foldable LED display screens during folding are too cumbersome. Therefore, a foldable LED display screen needs to be designed. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a foldable LED display screen to solve the technical problems mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A foldable LED display screen, including a bracket, the inside of the bracket is respectively connected with a housing, a second spur gear, and a second bevel gear through a sleeve, the bottom of the sleeve is connected with a support plate through an extension rod, the back of the support plate is connected with a base, the top of the base is respectively connected with a rack and a damping rod, one side inside the bracket is connected with a connecting shaft, the outside of the connecting shaft is respectively sleeved with a first spur gear and a first bevel gear, the surface of the housing is sleeved with a buffer pad, and a display screen is connected inside the housing.
[0006] By adopting the above technical solution, when the user needs to fold the display screen, the user places the hand on the top of the bracket and presses it down. When the bracket descends, the damping rod descends. The damping rod can support the bracket, but the telescopic movement of the damping rod can be controlled by the external force manually applied by the user to prevent the bracket from falling automatically. When the bracket descends, the extension rod enters the inside of the sleeve, and the rack enters the inside of the bracket. At this time, the first spur gear rotates through the rack, and the first spur gear drives the first bevel gear to rotate through the connecting shaft. The rotation of the first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the second spur gear to rotate through the sleeve. At the same time, the sleeve drives the extension rod to rotate through the protrusions arranged on the surface of the extension rod. When the bracket moves to the base, the first spur gear just rotates 360 degrees, and then the first bevel gear rotates 360 degrees. Since the diameter of the second bevel gear is four times that of the first bevel gear, the second bevel gear rotates 90 degrees, and finally drives the second spur gear to rotate 90 degrees to fold and close the housing. While the housing is being folded and closed, the support plate and the housing are synchronously folded and closed by the rotation of the extension rod, thus simplifying the folding steps of the foldable display screen.
[0007] Further, protrusions are arranged on both the outer surface and the back of the extension rod, and the extension rod is adapted to the sleeve.
[0008] By adopting the above technical solution, when the bracket descends, the extension rod enters the inside of the sleeve. When the second bevel gear rotates, the sleeve drives the extension rod to rotate through the protrusions arranged on the surface of the extension rod.
[0009] Further, the rack is slidably connected to the bracket, and the rack meshes with the first spur gear.
[0010] By adopting the above technical solution, when the bracket descends, the rack enters the inside of the bracket. At this time, the rack meshes with the first spur gear, and then the first spur gear rotates.
[0011] Further, both the first spur gear and the first bevel gear are fixedly connected to the connecting shaft, and the first bevel gear meshes with the second bevel gear.
[0012] By adopting the above technical solution, the first spur gear drives the first bevel gear to rotate through the connecting shaft. The first bevel gear meshes with the second bevel gear, and then the second bevel gear rotates.
[0013] Further, the diameter of the second bevel gear is four times the diameter of the first bevel gear.
[0014] By adopting the above technical solution, when the first bevel gear rotates 360 degrees, since the diameter of the second bevel gear is four times that of the first bevel gear, the second bevel gear rotates 90 degrees.
[0015] Furthermore, two second spur gears, extension rods, and sleeves are provided, and the two second spur gears are meshed with each other.
[0016] By adopting the above technical solution, when the second bevel gear rotates, it drives one second spur gear to rotate through the sleeve, causing the outer shell to fold, and meshing with the other second spur gear, thereby synchronously folding the two outer shells.
[0017] Furthermore, the buffer pad is made of rubber.
[0018] By adopting the above technical solution, rubber not only has excellent wear resistance and a long lifespan, but also has good elasticity. As a buffer pad, it can absorb a lot of vibration energy, achieving the effect of protecting the outer shell.
[0019] In summary, the main beneficial effects of the present utility model are as follows:
[0020] With the settings of the damping rod, rack, first spur gear, connecting shaft, first bevel gear, second bevel gear, second spur gear, extension rod, and sleeve in the present utility model, when the user needs to fold the display screen, the user places the hand on the top of the bracket and presses it down. When the bracket descends, the damping rod descends. The damping rod can support the bracket, but the user can manually apply an external force to control the telescopic movement of the damping rod to prevent the bracket from automatically falling. When the bracket descends, the extension rod enters the sleeve, and the rack enters the bracket. At this time, the first spur gear rotates through the rack, and the first spur gear drives the first bevel gear to rotate through the connecting shaft. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the second spur gear to rotate through the sleeve. At the same time, the sleeve drives the extension rod to rotate through the protrusions provided on the surface of the extension rod. When the bracket moves to the base, the first spur gear exactly rotates 360 degrees, thereby causing the first bevel gear to rotate 360 degrees. Since the diameter of the second bevel gear is four times that of the first bevel gear, the second bevel gear rotates 90 degrees, and finally drives the second spur gear to rotate 90 degrees to fold and close the outer shell. While the outer shell is folding and closing, the support plate and the outer shell are synchronously folded and closed through the rotation of the extension rod, thereby simplifying the folding steps of the foldable display screen.

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0027] The embodiments of the present utility model will be described below according to its overall structure.
[0028] A foldable LED display screen, as Figures 1-4 shown, a foldable LED display screen includes a bracket 1. Inside the bracket 1, a housing 12, a second spur gear 7 and a second bevel gear 6 are respectively connected through a sleeve 15. The bottom of the sleeve 15 is connected to a support plate 11 through an extension rod 9. Protrusions are provided on the outer surface and the back of the extension rod 9, and the extension rod 9 is adapted to the sleeve 15. When the bracket 1 descends, the extension rod 9 enters the inside of the sleeve 15. When the second bevel gear 6 rotates, the sleeve 15 drives the extension rod 9 to rotate through the protrusions provided on the surface of the extension rod 9. The back of the support plate 11 is connected to a base 10. A rack 2 and a damping rod 8 are respectively connected to the top of the base 10. The damping rod 8 can support the bracket 1, but the telescoping of the damping rod 8 can be controlled by manually applying an external force by the user to prevent the bracket 1 from automatically falling. One side inside the bracket 1 is connected to a connecting shaft 4. A first spur gear 3 and a first bevel gear 5 are respectively sleeved outside the connecting shaft 4. The first spur gear 3 drives the first bevel gear 5 to rotate through the connecting shaft 4. A buffer pad 14 is sleeved on the surface of the housing 12. The housing 12 reduces bumps through the buffer pad 14, plays a role in protecting the housing 12 and preventing dust from falling into the display screen 13 after closing. A display screen 13 is connected inside the housing 12, and various images are displayed through the display screen 13.
[0029] Refer to Figures 1-4In the above embodiment, the rack 2 is slidably connected to the bracket 1, and the rack 2 is meshed with the first spur gear 3. When the bracket 1 descends, the rack 2 enters the interior of the bracket. At this time, the rack 2 is meshed with the first spur gear 3, thereby rotating the first spur gear 3. The first spur gear 3 and the first bevel gear 5 are both fixedly connected to the connecting shaft 4, and the first bevel gear 5 is meshed with the second bevel gear 6. The first spur gear 3 drives the first bevel gear 5 to rotate through the connecting shaft 4, and the first bevel gear 5 is meshed with the second bevel gear 6, thereby rotating the second bevel gear 6.
[0030] See also Figures 1-4 In the above embodiment, the diameter of the second bevel gear 6 is four times the diameter of the first bevel gear 5. When the first bevel gear 5 rotates 360 degrees, since the diameter of the second bevel gear 6 is four times that of the first bevel gear 5, the second bevel gear 6 rotates 90 degrees. Two second spur gears 7, extension rods 9 and sleeves 15 are provided, and the two second spur gears 7 are meshed. When the second bevel gear 6 rotates, one second spur gear 7 is driven to rotate through the sleeve 15, and the outer shell 12 is folded at the same time. By meshing with the other second spur gear 7, the two outer shells 12 are folded synchronously.
[0031] The implementation principle of this embodiment is as follows: first, when the user needs to fold the display screen 13, the user places his hand on the top of the bracket 1 to press it down. When the bracket 1 descends, the damping rod 8 descends. The damping rod 8 can support the bracket 1, but the user can control the extension and retraction of the damping rod 8 by manually applying external force to prevent the bracket 1 from falling automatically. When the bracket 1 descends, the extension rod 9 enters the sleeve 15, and the rack 2 enters the bracket 1. At this time, the first spur gear 3 is rotated through the rack 2, and the first spur gear 3 drives the first bevel gear 5 to rotate through the connecting shaft 4. The rotation of the first bevel gear 5 drives the second bevel gear 6 to rotate, and the second bevel gear 6 drives the second spur gear 7 to rotate through the sleeve 15. At the same time, the sleeve 15 drives the extension rod 9 to rotate through the protrusion set on the surface of the extension rod 9. When the bracket 1 moves to the base 1 0, the first spur gear 3 rotates exactly 360 degrees, thereby causing the first bevel gear 5 to rotate 360 degrees. Since the diameter of the second bevel gear 6 is four times that of the first bevel gear 5, the second bevel gear 6 is rotated ninety degrees, and finally the second spur gear 7 is driven to rotate ninety degrees to fold and close the housing 12. While the housing 12 is folded and closed, the support plate 11 and the housing 12 are synchronously folded and closed through the rotation of the extension rod 9. The housing 12 reduces bumps through the buffer pad 14, which plays a role in protecting the housing 12 and preventing dust from falling into the display screen 13 after closing. At this point, the display screen 13 is folded. When the user needs to open the display screen 13, the user presses the base 10 to stretch the bracket 1 or pulls open either the support plate 11 or the housing 12 to open the display screen 13. The principle is opposite to that when folding the display screen 13.
