Description

Technical Field

[0001] The present invention relates to the field of display devices, and particularly relates to a full-screen touch and reinforcement display. Background Art

[0002] With the continuous development of social economy and the continuous improvement of people's living standards, users' requirements for the experience of displays are also getting higher and higher. A full-screen touch display with narrower borders, higher screen-to-body ratio, and capable of providing a larger visible area and better immersion is gradually widely used. A full-screen touch display is a display with a design that fully covers the screen and supports touch operations at the same time. Due to the adoption of capacitive touch technology, users can directly operate on the screen with their fingers or a stylus without the need for an additional mouse or keyboard. Full-screen touch displays have a wide range of applications in many fields, such as conference presentations, digital interactive displays, education and training, medical diagnosis, game entertainment, etc.

[0003] However, there are still some deficiencies in the current full-screen touch and reinforcement display. The existing full-screen touch and reinforcement display is not placed horizontally or vertically alone. During use, according to different usage scenarios and users, the full-screen touch and reinforcement display needs to be flipped to adjust the display angle of the full-screen touch and reinforcement display. The common flipping component is adjusted by using a bolt fastening method. However, the long-term loosening and tightening of the bolts will cause the screw holes to become slippery and cannot be used for a long time. At the same time, during use, there will inevitably be dust adsorbed on the surface current of the full-screen touch and reinforcement display and remaining on the surface. Factors such as sweat on the user's hands during use cause traces to remain on the full-screen touch and reinforcement display, affecting the appearance and hygiene conditions of the full-screen touch and reinforcement display.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: Refer to Figures 1 - 8 A full-screen touch and reinforcement display shown in the figure, including a base 1, a full-screen body 6 is arranged on the upper side of the base 1, a traction chute 10 is opened on the upper side of the base 1, a cleaning mechanism is arranged above the base 1, a water storage tank is opened on the lower side of the base 1, and an installation groove 14 is opened on the lower side of the base 1;

[0031] The cleaning mechanism includes a flipping component arranged above the base 1. The flipping component includes that the rear side of the full-screen body 6 is fixedly connected to the inner wall of the placing groove. The inner wall of the traction chute 10 is rotatably connected with a lead screw 11. The surface of the lead screw 11 is threadedly connected with a traction slider 12. The lower side of the traction slider 12 is slidably connected to the inner bottom wall of the traction chute 10. The upper side of the traction slider 12 is rotatably connected to the front side of the placing plate 5. Both the left and right sides of the placing plate 5 are rotatably connected with limit rods 7. The end of the limit rod 7 far from the placing plate 5 is rotatably connected to the upper side of the base 1. The inner wall of the installation groove 14 is fixedly connected with a cleaning component;

[0032] The flipping component is used to drive the full-screen body 6 to accurately control the flipping angle, which is convenient for the user to watch better. The cleaning component is used to be linked with the flipping component to spray out the cleaning agent, which is convenient for the user to clean the full-screen body 6.

[0033] By means of the above structure, by setting the base 1 as the installation platform, the base 1 itself has a certain weight and can be used as a counterweight to stabilize the center of gravity of the entire device. The full-screen body 6 is an all-in-one machine that integrates original parts and electronic components and has the necessary functions, similar to a tablet computer. In order to facilitate drawing display and maintain the aesthetics of the drawing display, the proportion of the full-screen body 6 is reduced, and there is a certain error with the actual size. The screw rod 11 is driven by the motor built into the base 1. There is no special choice for the motor model, and a general model is sufficient, so it is not shown in the attached drawings. When the motor is running, the screw rod 11 can be driven to rotate. The forward rotation of the motor drives the screw rod 11 to rotate clockwise, driving the traction slider 12 to move backward. Under the restriction of the limit rod 7, the placement plate 5 drives the full-screen body 6 to flip, allowing the user to touch the screen better. The reverse rotation of the motor drives the screw rod 11 to rotate counterclockwise, driving the traction slider 12 to move forward, and retracting the full-screen body 6 to a narrow space inside the device. The device can also be directly placed on the ground or mounted on the wall for use.

[0034] Furthermore, the flip assembly includes a magnetic slide groove 8 opened on the upper side of the base 1, the number of the magnetic slide grooves 8 is three, and the three magnetic slide grooves 8 are arranged in a row and multiple columns on the upper side of the base 1, the number of the traction slide grooves 10 is two, and the two traction slide grooves 10 are symmetrically arranged on the upper side of the base 1 with the vertical center line of the upper side of the base 1 as the axis of symmetry, and the number of the mounting grooves 14 is two, and the two mounting grooves 14 are symmetrically arranged on the lower side of the base 1 with the vertical center line of the lower side of the base 1 as the axis of symmetry.

[0035] By providing multiple magnetic slide grooves 8 to accommodate multiple first sliders to share the downward pressure from the placement plate 5, it is possible to avoid the traction slider 12 being subjected to too much pressure, which may affect the rotation of the screw rod 11 and make it impossible to normally drive the full-screen body 6 to flip. The symmetrically designed traction slide grooves 10 also allow the traction slider 12 to apply a more balanced traction force to the placement plate 5, reducing the possibility of the placement plate 5 deviating sideways under unilateral traction.

[0036] Furthermore, the flip assembly includes a magnetic window opened on the inner bottom wall of the magnetic slide 8 and penetrating the mounting groove 14. The inner bottom wall of the magnetic slide 8 is slidably connected with a magnetic slider 9, and the upper side of the magnetic slider 9 is rotatably connected to the front side of the placement plate 5.

[0037] By setting the magnetic suction groove 8 to be a dovetail groove, the magnetic slider 9 can be prevented from slipping out of the magnetic suction groove 8. The magnetic slider 9 is embedded with a magnet inside, which can adsorb some components. There is an obstacle of the placement plate 5 between the magnetic slider 9 and the full-screen body 6, and the magnet of the magnetic slider 9 will not interfere with the normal use of the full-screen body 6.

[0038] Further, the flipping component includes a dust-proof strip 2 detachably connected to the upper side of the base 1. An installation hole is formed in the rear side of the dust-proof strip 2, and a dust-proof cover 3 is slidably connected to the inner wall of the installation hole. A handle 4 is fixedly connected to the upper side of the dust-proof cover 3.

[0039] By providing the dust-proof strip 2 and the dust-proof cover 3, the full-screen body 6 is protected. The dust-proof strip 2 can be very conveniently removed from the base 1 through a simple snap design, facilitating the user to better use the full-screen body 6 without being interfered by the dust-proof strip 2 during use.

[0040] Further, the cleaning component includes a sealing sleeve 15 fixedly connected to the inner wall of the installation groove 14. A connection hole is formed in the rear side of the sealing sleeve 15, and a connecting rod 17 is slidably connected to the inner wall of the connection hole.

[0041] By providing the sealing sleeve 15 as an intermediate storage point for the cleaning liquid, since the capacity of the sealing sleeve 15 is limited, it will not cause waste of the cleaning agent. The opening of the connection hole facilitates the installation of the connecting rod 17.

[0042] Further, the cleaning component further includes a piston 16 fixedly connected to the front end of the connecting rod 17, and a magnetic connection block 18 fixedly connected to the rear end of the connecting rod 17 and cooperating with the magnetic slider 9.

[0043] By providing the piston 16 that closely fits the inner wall of the sealing sleeve 15, it is ensured that the inside of the sealing sleeve 15 will not leak air. The sealing sleeve 15, the piston 16, and the connecting rod 17 form a suction and injection component with the same principle as a syringe. There is also a magnet inside the magnetic connection block 18. The opening of the magnetic window reduces the obstruction between the magnetic slider 9 and the magnetic connecting plate, allowing there to be sufficient magnetic force adsorption between the magnetic connection block 18 and the magnetic slider 9, and the magnetic connection block 18 can move under the traction of the magnetic slider 9.

[0044] Further, the cleaning component further includes a water storage box 13 fixedly connected to the inner wall of the water storage tank. A water absorption hole is formed in the front side of the sealing sleeve 15, and a water absorption pipe 19 is fixedly connected to the inner wall of the water absorption hole. One end of the water absorption pipe 19 away from the sealing sleeve 15 penetrates the inner wall of the water storage box 13, and a water absorption check valve 20 is fixedly connected to the surface of the water absorption pipe 19.

[0045] By providing the water storage box 13 to store the cleaning liquid, and the cleaning liquid contains bactericidal and disinfectant components, which can effectively remove the bacteria and fingerprint marks remaining on the full-screen body 6. The water absorption check valve 20 can limit the flow direction of the disinfectant in the water absorption pipe 19. When the piston 16 moves backward, the cleaning agent in the water storage box 13 can be drawn into the sealing sleeve 15 through the water absorption pipe 19.

[0046] Further, the cleaning component further includes a water outlet hole opened in the front side of the sealing sleeve 15. The inner wall of the water outlet hole is fixedly connected with a water outlet pipe 21. One end of the water outlet pipe 21 away from the sealing sleeve 15 penetrates through the front inner wall of the dust-proof strip 2 and is fixedly connected with a spray head. A water outlet one-way valve 22 is fixedly connected to the surface of the water outlet pipe 21.

[0047] By setting the water outlet one-way valve 22 to restrict the flow direction of the disinfectant in the water outlet pipe 21, when the piston 16 moves forward, the cleaning agent in the sealing sleeve 15 can be discharged from the sealing sleeve 15 through the water outlet pipe 21 and finally form a water mist through the spray head at the end and be sprayed onto the surface of the full-screen body 6 that is being laid flat. This can not only prevent a large amount of water flow from directly spraying on the full-screen body 6 and causing faults in the full-screen body 6, but also expand the distribution of the cleaning agent on the full-screen body 6, facilitating the user to better clean the surface of the full-screen body 6.

[0048] The working principle of the present invention is as follows: For a full-screen touch reinforced display, first, push open the dust-proof cover 3 through the handle 4 to expose the full-screen body 6. When necessary, the dust-proof strip 2 can also be directly removed to avoid interference from the dust-proof cover 3 when the user uses the full-screen body 6. When the full-screen body 6 needs to be flipped, start the motor. The forward rotation of the motor drives the lead screw 11 to rotate clockwise. The rotation of the lead screw 11 drives the traction slider 12 to move. Under the restriction of the limit rod 7, the placement plate 5 drives the full-screen body 6 to flip, enabling the user to better touch the screen. As the placement plate 5 moves, the magnetic slider 9 moves backward. During the movement, the magnetic connection block 18 is pulled backward. When the magnetic connection block 18 moves backward to the position it can reach, the magnetic slider 9 separates from the magnetic connection block 18. However, during the backward movement of the magnetic connection block 18, the magnetic connection block 18 drives the connecting rod 17 to move. The movement of the connecting rod 17 drives the piston 16 to move backward. The cleaning agent in the water storage box 13 is sucked into the sealing sleeve 15 through the water suction pipe 19. After the full-screen is used, control the motor to reverse, so that the lead screw 11 rotates counterclockwise to drive the traction slider 12 to move, and the full-screen body 6 is laid flat. During the laying-flat process, the magnetic connection block 18 drives the connecting rod 17 to move. The movement of the connecting rod 17 drives the piston 16 to move forward. The cleaning agent in the sealing sleeve 15 is discharged through the water outlet pipe 21, and the cleaning agent is sprayed onto the surface of the full-screen body 6 under the action of the spray head, facilitating the user to better clean the surface of the full-screen body 6.

[0049] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
