Single-sided drive has higher requirements on motor performance, and the motor screen module has greater torsional resistance. This requires a single motor with larger size and power to output greater torque, resulting in greater noise and poor fatigue durability of the whole machine. Therefore, we need to propose a dual-drive gearbox flip mechanism. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 , the present invention provides a technical solution:

[0028] A double-drive gearbox flip mechanism includes a control panel 4 for installing a drive module and a control module, a display screen module 3 is installed on the control panel 4; a drive mechanism for driving the display screen module 3, the drive mechanism includes a first drive gearbox 5 and a second drive gearbox 6, a first shaft rod 7 and a second shaft rod 8 are respectively provided at both ends of one side of the display screen module 3, the first shaft rod 7 and the second shaft rod 8 are respectively connected to the first drive gearbox 5 and the second drive gearbox 6 through gear transmission; and a power assembly for providing power for the drive mechanism is also included. The ends of the first shaft rod 7 and the second shaft rod 8 are fixedly connected to driven gears, and the two sets of driven gears are connected to the gears inside the first drive gearbox 5 and the gear set inside the second drive gearbox 6 through meshing.

[0029] The present invention drives the display screen module 3 to flip simultaneously by installing a first driving gear box 5 and a second driving gear box 6 on both sides of the display screen module 3 on the control board 4. Compared with the traditional single-sided gear box drive method, the size of the motor is reduced, the torque of a single motor is reduced, and the noise is smaller. At the same time, the torsional force of the display screen module 3 can be reduced, thereby reducing costs, greatly improving the fatigue durability of the equipment, and the flipping process of the display screen module 3 is more stable.

[0030] The power assembly includes a first motor 9 and a second motor 10 respectively installed on both sides of the control board 4, and the first motor 9 and the second motor 10 are respectively connected to the first drive gear box 5 and the second drive gear box 6. The output shaft ends of the first motor 9 and the second motor 10 are both equipped with driving gears, and the two sets of driving gears are connected to the gears inside the first gear box and the gear set inside the second drive gear box 6 by meshing.

[0031] By providing two groups of smaller motors to replace a single group of larger motors, the size of the motors is reduced, the torque of a single motor is reduced, and the noise is reduced.

[0032] See also Figure 2 , which is a traditional unilaterally driven display module, wherein a display module with a shaft is installed on a control board 4, and a driven gear and a driving gear box 2 are respectively arranged on both sides of the display module. The driving gear box 2 is driven by a single motor 11, and the driven gear box 1 does not provide power. The unilateral drive has higher requirements on the motor performance, and the motor screen module has a greater torsional resistance, which requires a single motor with a larger size and power to output a greater torque, resulting in greater noise of the whole machine and poor fatigue durability.

[0033] A controller 12 is also installed on the control board 4 , and the first motor 9 and the second motor 10 are both electrically connected to the controller 12 , and the controller 12 is configured as a PLC controller.

[0034] When the present invention is used in practice, the user issues a command through the control button in the cockpit. When the controller 12 on the control panel 4 receives the command, it transmits the signal to the first motor 9 and the second motor 10 at the same time. The first motor 9 and the second motor 10 drive the first drive gear box 5 and the second drive gear box 6. The first drive gear box 5 and the second drive gear box 6 simultaneously drive the two shafts of the display screen module 3 to flip open the display screen module 3 for the user to watch.

[0035] Among them, the control method of the control board 4 of the present application is to control the PLC controller built into the control board 4. The control circuit of the PLC controller can be realized by simple programming by technical personnel in this field, which belongs to the common knowledge in this field, and the present application document is mainly used to protect mechanical devices, so the present application document no longer explains the control method and circuit connection in detail.

[0036] An angle sensor is installed on the first shaft 7 , and the angle sensor signal is connected to the controller 12 .

[0037] By installing an angle sensor on the first shaft 7, the rotation angle of the display screen module 3 can be monitored in real time. The controller 12 receives the angle signal and performs integrated regulation, so that the user can adjust the rotation angle of the display screen module 3 as needed.

[0038] See also Figure 3-5 :

[0039] The control board 4 is also provided with a guide assembly for guiding the motion trajectory of the display screen module 3. The guide assembly includes two sets of guide arms 13, which are mounted on the control board 4 by fixing screws and are respectively located on both sides of the display screen module 3. The two sets of guide arms 13 are both arranged in a quarter-circle arc shape, and are provided with an arc-shaped notch 14 for guiding, and the arc of the arc-shaped notch 14 is consistent with that of the guide arm 13. Two sets of connecting columns 15 are symmetrically arranged on the two side walls of the display screen module 3, and a slider 16 is integrally formed at the end of the connecting column 15, and two sets of limit blocks 17 are symmetrically arranged on the slider 16, and the slider 16 is slidably arranged inside the arc-shaped notch 14, and the two sets of limit blocks 17 are respectively located on both sides of the guide arm 13.

[0040] By installing arc-shaped guide arms 13 on both sides of the display screen module 3 on the control panel 4, an arc-shaped notch 14 is provided on the guide arms 13, and connecting columns 15 with sliders 16 are provided on both side walls of the display screen module 3, and the sliders 16 and the arc-shaped notch 14 are slidably matched. In specific use, when the dual motors drive the display screen module 3 to flip, the sliders 16 slide correspondingly in the arc-shaped notch 14. The cooperation of the guide arms 13, the arc-shaped notch 14, the connecting columns 15 and the sliders 16 can play a good guiding role when the display screen module 3 is flipped, so that the display screen module 3 is flipped more smoothly and stably;

[0041] In addition, two groups of limit blocks 17 are provided on the slider 16 , and the two groups of limit blocks 17 are respectively located on both sides of the guide arm 13 , which can play a good limiting role and prevent the slider 16 from being separated during the sliding process.

[0042] One end of the two sets of guide arms 13 connected to the control board 4 is fixedly welded with a mounting plate 18, and the mounting plate 18 is symmetrically provided with mounting holes for mounting fixing screws.

[0043] By providing a mounting plate with mounting holes on the guide arm 13, the guide arm 13 can be mounted on the control board 4 by fixing screws in conjunction with the mounting holes. This is different from welding and is more convenient for installation and use, as well as for disassembly and replacement in the event of a fault.

[0044] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
