Description

Technical Field

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] like Figures 1 to 4 As shown in the figure, this invention discloses an adaptively adjustable operating screen system, including an operating screen assembly 1, a mounting base 2, and an operating screen adjustment assembly. A housing 5 is provided on the outer side of the mounting base. The operating screen assembly includes an operating screen 11, a screen camera 12, and a screen bracket 13. The screen camera is located on the top of the operating screen. An operating system motherboard is housed within the operating screen 11, which is touch-operated. The screen camera 12 is connected to the operating system motherboard within the operating screen 11 via a cable. The screen camera 12 incorporates a face recognition algorithm to detect the position and posture of the user's face within the camera's field of view. The operating screen 11 generates an electrical signal based on the position and posture of the user's face and transmits it to a control board 311 via a cable. One end of the screen bracket is hinged to the back of the operating screen.

[0025] The operation screen adjustment assembly includes a lead screw mechanism that drives the bottom side of the operation screen to reciprocate, a linkage mechanism that drives the end of the screen bracket away from the operation screen to move up and down through the lead screw mechanism, a control board 311, and position sensors 312 set at the starting and ending points of the movement on the bottom side of the operation screen. The screen camera is electrically connected to the operation screen, and the control board 311 is electrically connected to the operation screen 11, the lead screw mechanism, and the position sensor 312 respectively.

[0026] In this embodiment, the lead screw mechanism includes a lead screw 36 rotatably mounted on a mounting base plate via a lead screw mounting seat 39, a drive assembly for driving the lead screw to rotate, a lead screw slider 37 threadedly connected to the lead screw, and a lead screw slider end screen mounting seat 38 fixedly connected to the lead screw slider. Position sensors 312 are provided at both the starting point and the ending point of the movement of the lead screw slider. The lead screw slider end screen mounting seat is hinged to the bottom side of the operation screen. A first sliding groove is provided on the mounting base plate for sliding assembly with the lead screw slider end screen mounting seat.

[0027] In this embodiment, the drive assembly includes a motor 31 and a belt drive mechanism. The motor is fixedly mounted on the mounting base plate via a motor mounting bracket 33. The belt drive mechanism includes a motor pulley 32 mounted on the output end of the motor, a lead screw pulley 35 mounted on one end of the lead screw, and a synchronous belt 34 wound between the motor pulley and the lead screw pulley. The motor is electrically connected to the control board.

[0028] In this embodiment, the linkage mechanism includes a gear shaft 314 rotatably mounted on the mounting base plate via a gear shaft mounting seat 313, a gear 315 mounted on the gear shaft, a rack fixedly connected to the end of the screen bracket away from the operating screen, and a pressure roller assembly for maintaining meshing transmission between the rack and the gear. A lead screw bevel gear 310 is mounted on the end of the lead screw away from the lead screw pulley, and a shaft bevel gear 316 meshing with the lead screw bevel gear is mounted on the gear shaft. The pressure roller assembly includes a pressure roller 318 and a pressure roller mounting seat 317. The pressure roller mounting seat is set on the mounting base plate, and the pressure roller is mounted on the pressure roller mounting seat. The pressure roller is pressed tightly against the non-toothed side of the rack. In this embodiment, racks and pressure roller assemblies are provided on both sides of the screen bracket. The two pressure rollers 318 are pressed tightly against the upper surface of the rack, thereby ensuring that the rack meshes with the gear.

[0029] The mounting base plate is also provided with a guide mechanism 4 for guiding the movement of the bottom side of the operation screen. In this embodiment, guide mechanisms are provided on both sides of the operation screen. The guide mechanism includes a guide rail mounting seat 41 on the mounting base plate, a linear guide rail 42 on the guide rail mounting seat, a guide rail slider 43 slidably assembled with the linear guide rail, and a guide rail slider end screen mounting seat 44 fixedly connected with the guide rail slider. The guide rail slider end screen mounting seat is hinged to the bottom side of the operation screen. A second sliding groove is provided on the mounting base plate for slidably assembling with the guide rail slider end screen mounting seat.

[0030] The specific working principle is as follows:

[0031] When the operation screen 11 detects that the user's face is within the poor range of the screen camera's shooting range, it generates an electrical signal and transmits it to the control board 311 through a cable. As a result, the motor 31 is energized and rotates, driving the motor pulley 32 to rotate forward and backward. Then, through the synchronous belt 34, it drives the lead screw pulley 34 and the lead screw 36 to rotate forward and backward, thereby driving the lead screw slider 37 and the lead screw slider end screen mounting base 38 to move back and forth. This causes the operation screen 11 to move back and forth, and also causes the two sets of guide rail slider end screen mounting bases 44 to move back and forth on their respective linear guide rails 42.

[0032] When the operation screen 11 detects that the user's face is within the optimal range of the screen camera's shooting range, it generates an electrical signal and transmits it to the control board 311 via a cable. The control board 311 then drives the motor 31 to stop moving. When one of the two position sensors 312 detects that the screen mounting base 38 at the end of the lead screw slider has moved to the starting or ending position, it generates an electrical signal and transmits it to the control board 311 via a cable. The control board 311 then drives the motor 31 to stop moving, causing the operation screen 11 to stop at the foremost or rearmost position.

[0033] At the same time, when the lead screw 36 rotates, it will drive the lead screw bevel gear 310 to rotate in both directions. In turn, the lead screw bevel gear 310 drives the rotating shaft bevel gear 316 to rotate in both directions through gear transmission. This, in turn, drives the gear shaft 314 and the two gears 315 to rotate in both directions. Then, the two gears 315 drive the rack and screen bracket 11 to move up and down through gear transmission, thereby causing the operation screen 11 to swing and adjust the angle of the operation screen 11.

[0034] In this embodiment, when the motor 31 is not powered and is rotating, the operator can also apply force to the operation screen 11 by hand to drive the operation screen 11 to adjust its position and angle at the same time.

[0035] In this embodiment, the tail end of the screen bracket 13 is provided with two rack structures and corresponding gears 315 and two sets of pressure rollers 318. In other embodiments, the tail end of the screen bracket 13 may be provided with one or more rack structures and corresponding gears 315 and two sets of pressure rollers 318.

[0036] In this embodiment, two sets of sliding components 4 and corresponding bottom connecting shafts of the operation screen 11 are provided. In other embodiments, one or more sets of sliding components 4 and corresponding bottom connecting shafts of the operation screen 11 can be provided.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
