Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-7, the present invention provides a technical solution: a slide rail type OLED display screen comprises a supporting seat 1, a hydraulic rod 2, a display screen body 3, a spring 4, a limiting rod 5, a rack 6, a sliding block 7, a limiting block 8, a sliding groove 9, a first gear 10, a second gear 11, a third gear 12, a cover plate 13, a fourth gear 14 and a cleaning roller 15, wherein the hydraulic rod 2 is fixedly arranged inside the supporting seat 1, the display screen body 3 is fixedly arranged at the top of the hydraulic rod 2, the spring 4 is fixedly connected inside the display screen body 3, the limiting rod 5 is fixedly connected to the end part of the spring 4, the sliding block 7 is fixedly connected to one side of the rack 6, the limiting block 8 is fixedly connected to one side of the rack 6, the first gear 10 is rotatably connected inside the supporting seat 1, the second gear 11 is rotatably connected inside the supporting seat 1, the third gear 12 is rotatably connected inside the supporting seat 1, the cover plate 13 is embedded inside the supporting seat 1, and the fourth gear 14 is rotatably connected inside the supporting seat 1, and a cleaning roller 15 is rotatably connected to the inside of the support base 1.
Gag lever post 5 passes through and constitutes extending structure between spring 4 and the display screen body 3, and the biggest displacement volume of gag lever post 5 equals the minimum self deformation of spring 4 to 5 tip of gag lever post set up to hemispherical, and gag lever post 5 can compress spring 4 when moving towards display screen body 3 inboards, so can utilize spring 4's elastic potential energy to reset gag lever post 5.
The number of the racks 6 is two, the racks 6 are in meshed connection with the first gear 10, the length of each rack 6 is smaller than the circumference of the addendum circle of the first gear 10, and the first gear 10 can be driven to rotate by the movement of the racks 6.
The horizontal section of the sliding block 7 is T-shaped, the sliding block 7 is symmetrically arranged about the vertical central axis of the rack 6, the sliding block 7 is meshed with the sliding groove 9, and the sliding block 7 can enable the moving process of the rack 6 to be smoother.
The gear teeth 1301 are fixedly connected to the bottom of the cover plate 13, the gear teeth 1301 are distributed on the bottom of the cover plate 13 at equal intervals, the cover plate 13 and the third gear 12 are arranged in a one-to-one correspondence mode, the gear teeth 1301 and the third gear 12 are connected in a meshed mode, and therefore the cover plate 13 can be driven to move by the rotation of the third gear 12.
For the meshing connection between fourth gear 14 and the second gear 11, the rotation of second gear 11 can drive the rotation of fourth gear 14, through the transmission between the bevel gear, the rotation of fourth gear 14 can drive the rotation of cleaning roller 15, cleaning roller 15 and display screen body 3's surface contact, so cleaning roller 15 can clear up the surface of display screen body 3 when the pivoted, fourth gear 14 and fourth gear 14's addendum circle diameter equals second gear 11's addendum circle diameter.
The working principle is as follows: when the slide rail type OLED display screen is used, firstly, a certain understanding is given to the working principle of the slide rail type OLED display screen, as shown in fig. 1-6, when the display screen body 3 is not used, the hydraulic rod 2 is started to drive the display screen body 3 to descend, at this time, the limiting rod 5 is located above the limiting block 8, so the display screen body 3 drives the rack 6 to move downwards in the descending process, the rack 6 drives the first gear 10 to rotate in the downward moving process, the first gear 10 rotates to drive the third gear 12 to rotate, the third gear 12 rotates to drive the cover plate 13 to move towards the inner side of the supporting seat 1 until the cover plate 13 covers the upper side of the display screen body 3, so the display screen body 3 can be effectively protected, the service life of the display screen body 3 is prolonged, when the rack 6 cannot move downwards any more, the limiting rod 5 can continue to move downwards for a certain distance, in the process, the limiting rod 5 can move towards the inner side of the display screen body 3 under the limitation of the limiting block 8, meanwhile, the limiting rod 5 can compress the spring 4, when the limiting rod 5 is located below the limiting block 8, the elastic potential energy of the spring 4 can reset the limiting rod 5, when the display screen body 3 needs to be used, the hydraulic rod 2 is started, the hydraulic rod 2 drives the display screen body 3 to ascend, the transmission principle is the same as that when the display screen body 3 descends, in the process, the cover plate 13 can move towards the outer side of the display screen body 3, and the limiting rod 5 can be located above the limiting block 8 finally, so that the function of contracting the display screen body 3 is achieved;
as shown in fig. 3 and 7, the rotation of the second gear 11 drives the fourth gear 14 to rotate, and the rotation of the fourth gear 14 drives the cleaning roller 15 to rotate through the transmission between the bevel gears, so that the cleaning roller 15 is in contact with the surface of the display screen body 3, and the surface of the display screen body 3 can be cleaned by the cleaning roller 15 during the rotation, thereby realizing the function of automatically cleaning the surface of the display screen body 3 and saving manpower.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
