Description

Technical Field

[0001] This utility model relates to the field of back panel technology, and more specifically to a frameless integrated back panel. Background Technology

[0002] All-in-one commercial display educational machines are a product of the deep integration of commercial display technology and educational scenarios. They integrate the functions of a computer, TV, tablet, speakers, whiteboard, projector, and Internet, and are intelligent devices designed specifically for educational scenarios. The back panel is a key support structure for the LCD screen. Its core function is to provide a stable backlight source for the LCD panel, ensuring that the image is clearly visible in dark environments. The frameless integrated back panel is a design solution that integrates the back panel and the middle frame into a single structural component. It integrates the back panel, side panels, and bottom panel, and is made of thin metal sheet by bending or stamping. Its core is to eliminate the independent front frame and directly support the display panel and internal components through the back panel.

[0003] Existing all-in-one commercial display educational machines are typically placed on a tabletop using a support frame on the back panel. Once the back panel and frame are fixed, the tilt angle is generally not adjustable. Sometimes, the tabletop is at a certain height, making it difficult to view the display screen perpendicular to the ground. The inability to adjust the angle results in a suboptimal viewing experience. Secondly, once the frame is fixed, it is not convenient to adjust the height of existing all-in-one commercial display educational machines. When height adjustment is needed, it is generally necessary to replace the frame or, if the height adjustment is insufficient, to raise it by adding a shim. Replacing the frame is cumbersome, and adding a shim can make the educational machine prone to tipping over and damage, which is detrimental to its use. Utility Model Content

The adjustment mechanism 2 includes a back frame 201, with side mounting plates 202 fixedly connected to both sides of the front side of the back frame 201. Vertical brackets 203 are movably connected to both sides of the front side of the back frame 201 near the center. The buckle 103 and the screw holes on it are used to fix the motherboard, power board and other core components. The limiting groove 102 is used to ensure the stability of the backlight module and to assist in heat dissipation.

[0024] In a preferred embodiment, the front of the vertical bracket 203 has a mounting hole, and the front of the vertical bracket 203 and the front of the side mounting plate 202 are located on the same vertical plane. A rotating adjustment block 204 is fixedly connected to the middle of the back of the back frame 201. The top of the back of both sides of the rotating adjustment block 204 has a downward adjustment arc groove 205, and the bottom of the back of both sides of the rotating adjustment block 204 has an upward adjustment arc groove 206. By loosening the first fixing bolt 302, the rotating adjustment block 204 can be rotated. When adjusting the angle upwards, the lowering arc groove 205 of the rotating adjustment block 204 remains stationary, while the upper arc groove 206 rotates backwards along the first fixing bolt 302. When adjusting the angle downwards from the vertical position, the upper arc groove 206 remains stationary, while the lower arc groove 205 rotates forwards along the first fixing bolt 302. After adjustment, tightening the first fixing bolt 302 will fix the rotating adjustment block 204, which is beneficial for adjusting the tilt angle of the educational machine and obtaining a better viewing experience.

[0025] In a preferred embodiment, the rotating mechanism 3 includes a rotating block 301. First fixing bolts 302 are fixedly connected to the front sides of both sides of the rotating block 301. The first fixing bolts 302 are adapted to the lowering arc groove 205 and the uppering arc groove 206. A first threaded rod 303 is movably connected to the center of the back side of the rotating block 301. A handle 304 is fixedly connected to the back side of the first threaded rod 303. By rotating the handle 304, the first threaded rod 303 is disengaged from the fixing groove 403, allowing the rotating block 301 to rotate. Rotating the rotating block 301 adjusts the horizontal angle of the back panel body 1. Rotating the handle 304 again causes the first threaded rod 303 to rotate and insert into the fixing groove 403, fixing the rotating block 301 and preventing it from rotating. This facilitates adjusting the horizontal angle of the educational machine, allowing it to be viewed from different angles.

[0026] In a preferred embodiment, the lifting bracket 4 includes an upper tube 401, with lifting grooves 402 formed in the middle of both sides of the upper tube 401, and a fixing groove 403 formed at the top of the outer side of the upper tube 401. The top and bottom of the fixing groove 403 are provided with threads, and the threads of the fixing groove 403 are adapted to the first threaded rod 303.

[0027] In a preferred embodiment, a sleeve 404 is movably sleeved on the outer bottom of the upper tube 401. A second threaded rod 405 is movably connected to the top of one side of the sleeve 404. A knob 406 is fixedly connected to one end of the second threaded rod 405, and the other end of the second threaded rod 405 extends into the inner wall of the sleeve 404. The second threaded rod 405 is adapted to the lifting groove 402. By rotating the knob 406, the second threaded rod 405 is disengaged from the sleeve 404, and the upper tube 401 is moved up and down to adjust the height of the back plate body 1. After moving to the desired height, the second threaded rod 405 is rotated and inserted, and the knob 406 is tightened to fix it. This facilitates the adjustment of the height of the back plate body 1 and reduces the risk of using a shim to increase the height.

[0029] The working principle of this utility model:

[0030] In use, by rotating knob 406, the second threaded rod 405 is disengaged from sleeve 404, and the upper tube 401 is moved up and down to adjust the height of the backplate body 1. After moving to the desired height, the second threaded rod 405 is rotated and inserted, and knob 406 is tightened to fix it. This facilitates the adjustment of the height of the backplate body 1 and reduces the risk of using shims to increase the height. By rotating handle 304, the first threaded rod 303 is disengaged from the fixing groove 403, allowing the rotating block 301 to rotate. Rotating the rotating block 301 adjusts the horizontal angle of the backplate body 1. Rotating handle 304 again rotates the first threaded rod 303 into the fixing groove 403, fixing the rotating block 301 so that it cannot rotate. This facilitates the adjustment of the backplate body 1. The horizontal angle of the educational machine allows it to be viewed from different angles. By loosening the first fixing bolt 302, the rotating adjustment block 204 can be rotated. When adjusting the angle upward from the vertical position, the lower adjustment arc groove 205 of the rotating adjustment block 204 remains stationary, while the upper adjustment arc groove 206 rotates backward along the first fixing bolt 302. When adjusting the angle downward from the vertical position, the upper adjustment arc groove 206 remains stationary, while the lower adjustment arc groove 205 rotates forward along the first fixing bolt 302. After adjustment, tightening the first fixing bolt 302 will fix the rotating adjustment block 204, which is beneficial for adjusting the tilt angle of the educational machine and obtaining a wider viewing experience.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
