DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] The following is an introduction to the application scenarios of this application. On the work surfaces of large electronic equipment such as display consoles and cabinets, a variety of small electronic modules are often integrated and installed. These small electronic modules can be operating keyboards, display screens, or touch screens according to specific application scenarios. When these small electronic modules are in use, due to the limited operating space, the angles need to be adjusted and the position can be locked to facilitate the operator's use of the module. When adjusting the angle of the module, it is necessary to occupy as little equipment space as possible. This application is a solution proposed to achieve the flipping of the above-mentioned small electronic modules.

[0028] See also Figure 1 and Figure 2 A flip mechanism of a table module includes a table 1 and a module 2. The table 1 is a work table for large electronic equipment such as a display console and a cabinet. The module 2 can be an operating keyboard, a display screen or a touch screen. A flip receiving cavity 3 is provided on the table 1. The rotating shaft of the module 2 is rotatably connected to the two opposite side walls of the flip receiving cavity 3, so that the module 2 can be rotated out of or into the flip receiving cavity 3. A limit block is provided in the flip receiving cavity 3 to limit the rotation angle of the module 2, so that the maximum rotation angle of the module 2 is limited within a set range. Specifically, the rotating shaft of the module 2 is rotatably connected to the two opposite side walls of the flip receiving cavity 3.

[0029] See also Figure 2 A driving gear 4 is provided on the table 1 to drive the module 2 to rotate relative to the table 1, and a driven rack 5 is provided on the module 2. The driving gear 4 and the driven rack 5 are engaged and transmitted through at least one driven gear 6. Of course, the driving gear 4 can also be directly engaged and transmitted with the driven rack 5. The driving gear 4 drives the driven rack 5 to rotate, and then drives the module 2 to rotate relative to the table 1, thereby realizing the adjustment of the angle of the module 2. A locking mechanism is also provided between the table 1 and the module 2 to lock the relative position between the table 1 and the module 2.

[0030] See also Figure 2-Figure 4 Specifically, the locking mechanism includes a gear fixing member 7, a pressing push rod 8, a first elastic reset member 9 and a second elastic reset member 10. The gear fixing member 7 is rotatably connected to the table 1 through a rotating shaft. A card block 11 that can be inserted into the tooth groove of the driving gear 4 is provided on the gear fixing member 7. The pressing push rod 8 is slidably installed in the slide groove on the table 1. The pressing push rod 8 is provided with an extrusion inclined surface 12. The gear fixing member 7 is provided with a matching inclined surface 13 that matches the extrusion inclined surface 12. When the pressing push rod 8 is pressed, the extrusion inclined surface 12 squeezes the matching inclined surface 13 to drive the gear fixing member 7 to rotate around its own rotating shaft relative to the table 1, so that the card block 11 comes out of the tooth groove (corresponding to the unlocking position of the gear fixing member 7). The driving gear 4 is unlocked, at which time the driving gear 4 can rotate freely, and the flip angle of the module 2 can be flexibly adjusted. The first elastic reset member 9 is connected between the pressing push rod 8 and the table 1 to drive the pressing push rod 8 to reset when the pressing push rod 8 is released. The second elastic reset member 10 is connected between the gear fixing member 7 and the table 1 to drive the gear fixing member 7 to reset after the pressing push rod 8 is reset, so that the card block 11 is re-engaged in the tooth groove (corresponding to the locking position of the gear fixing member 7), locking the position of the driving gear 4. At this time, the driving gear 4 cannot rotate relative to the table 1 around its own rotation axis, and the module 2 cannot rotate around its own rotation axis. The relative position between the module 2 and the table 1 is locked.

[0031] In some possible implementations, multiple gear fixing members 7 are evenly spaced along the circumference of the drive gear 4. One end of a push rod 8 extends outside the table 1 and connects to a button 14. The other end coaxially passes through the drive gear 4 and connects to a tapered block 15. The outer surface of the tapered block 15 directly forms the extrusion slope 12. The multiple gear fixing members 7 are evenly distributed around the periphery of the tapered block 15. This arrangement ensures reliable locking of the drive gear 4. Furthermore, multiple gear fixing members 7 can be switched between locked and unlocked positions using the same push rod 8, resulting in a simple structure and easy operation.

[0032] In the actual design, the table top 1 is also provided with a toggle roller 16 that drives the driving gear 4 to rotate. The toggle roller 16 is rotatably installed in the roller mounting groove on the table top 1, and partially protrudes out of the table top 1. The rotating shaft of the toggle roller 16 and the rotating shaft of the driving gear 4 are fixedly connected by a mortise and tenon structure. By screwing the exposed part of the toggle roller 16 to drive the toggle roller 16 to rotate, the driving gear 4 can be driven to rotate, thereby realizing the adjustment of the flip angle of the module 2, which is easy to operate.

[0033] Specifically, a bearing and a rotating shaft are installed between the module 2 and the table 1. The module 2 can rotate along the rotating shaft toward the outside of the table 1. The button 14 is arranged on the left side of the table 1 by the button 14 flange. The first elastic reset member 9 is a compression spring. The compression spring is installed between the pressing push rod 8 and the toggle roller 16. The rotating shaft of the toggle roller 16 is installed in the table 1 through a pair of bearings. The toggle roller 16 can rotate around the bearings, and a part of the toggle roller 16 is exposed from the table 1. The toggle roller 16 is fixedly connected to the driving gear 4 by a mortise and tenon structure. The conical block 15 is fixedly connected to the pressing push rod 8 by a mortise and tenon structure. The driving gear 4 and the driven gear 6 are both installed in the gear box body, and the driven gear 6 drives the driven rack 5 to rotate. The second elastic return member 10 is a torsion spring installed between the gear fixing member 7 and the gear box. The driven rack 5 and the module 2 are fixedly connected by bolts. When the driven rack 5 moves, it drives the module 2 to rotate. The bottom end of the driven rack 5 has a limit block, which allows the module 2 to rotate within a range of 0° to 45° relative to the table 1. Of course, the first elastic return member 9 and the second elastic return member 10 can also be other elastic elements such as rubber springs.

[0034] A matching bevel 13 is machined at the place where the gear fixing part 7 contacts the conical block 15. The rotating axis of the gear fixing part 7 is parallel to the rotating axis of the driving gear 4. When the button 14 is pressed, the push rod 8 and the conical block 15 are pressed inward, causing the gear fixing part 7 to rotate, thereby causing the block 11 of the gear fixing part 7 to disengage from the tooth groove of the driving gear 4, so that the driving gear 4 can rotate.

[0035] like Figures 1 to 4 As shown, to adjust the angle of module 2, button 14 is pressed toward the inside of tabletop 1. Push rod 8 and tapered block 15 follow button 14 and move inward. Gear fixture 7 rotates along its axis, and block 11 of gear fixture 7 disengages from drive gear 4, allowing it to rotate freely and causing the torsion spring to twist. At this point, toggle wheel 16 is rotated, driving drive gear 4, which in turn drives driven gear 6, which in turn drives driven rack 5, which in turn drives module 2, causing it to rotate about its axis, thereby adjusting the angle of module 2. When button 14 is released, the torsion spring, returning to its original shape, drives gear fixture 7 back into place. Block 11 on gear fixture 7 reenters the tooth groove of drive gear 4, preventing further rotation of drive gear 4. The cooperating gear and toggle wheel 16 also become inoperable. Module 2 is now fixed at a predetermined angle, thus achieving fixed adjustment of its angle.

[0036] The above embodiments are merely examples to clearly illustrate the present invention and are not intended to limit its implementation. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
