[0027] The embodiment of the utility model provides an automatically switching double-sided keyboard.

[0028] See also Figure 1 、 Figure 2 and Figure 3 , including two keyboard support plates 1, each of which has two storage grooves 9 on its outer surface, and a pad 10 hinged to the inside of each storage groove 9 through a pin shaft. Through the arrangement of the storage grooves 9 and the pads 10, the user can store the pads 10 in the storage grooves 9 or take the pads 10 out of the storage grooves 9, so that the user can selectively raise one end of the keyboard support plate 1 at a certain angle according to usage requirements, thereby improving the usage comfort of the double-sided keyboard.

[0029] See also Figure 2 The middle part of the two keyboard support plates 1 is fixedly connected with a fixing frame 2. The fixing frame 2 adopts a hollow design to reduce the cost of device production. The material of the fixing frame 2 is a steel structure with high strength and toughness. It can support the placed input keyboard 8 and maintain the stability of the input keyboard 8 during use.

[0030] See also Figure 1 and Figure 2Two groups of fixing blocks 7 are fixedly connected to the outer surface of the fixing frame 2. Two input keyboards 8 are set on the outside of the fixing frame 2. Each fixing block 7 is plugged into the corresponding input keyboard 8. The input keyboard 8 is a prior art and will not be described in detail in this application. The two input keyboards 8 are a mechanical keyboard suitable for playing games and a touch keyboard suitable for office use. The user can select different input keyboards 8 through the flipping device to meet the needs of using different input keyboards 8. The fixing block 7 can improve the supporting stability of the fixing frame 2 on the input keyboard 8, and prevent the input keyboard 8 from falling off from the fixing frame 2 during flipping and use.

[0031] See also Figure 3 and Figure 5 Each keyboard support plate 1 is rotatably connected to two transmission gears 3, and the outer surface of each transmission gear 3 is fixedly connected to a rotating rod 5. When the rotating rod 5 rotates, it can drive the transmission gear 3 to rotate. The rotation of the transmission gear 3 can drive the two transmission racks 402 to move inside the keyboard support plate 1 under the effect of meshing, thereby controlling the sliding of the limit slider 403, making it convenient for the user to disassemble the corresponding keyboard.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 Each rotating rod 5 passes through the keyboard support plate 1 and is rotatably connected to the keyboard support plate 1. The end of each rotating rod 5 away from the transmission gear 3 is fixedly connected to the control knob 6. There is a certain friction between the control knob 6, the rotating rod 5 and the keyboard support plate 1 to prevent the rotating rod 5 and the control knob 6 from rotating on their own without external force and affecting the limiting effect of the limit slider 403 on the input keyboard 8. The rotation of the control knob 6 drives the rotating rod 5 to rotate, and the rotation of the rotating rod 5 drives the transmission gear 3 to rotate, thereby providing power for the subsequent operation of the limiting mechanism 4.

[0033] See also Figure 3 and Figure 4 Two limiting mechanisms 4 are provided on the outside of each transmission gear 3. The limiting mechanism 4 includes a transmission slider 401 sliding inside the keyboard support plate 1. A plurality of slideways are provided inside the keyboard support plate 1 so that the transmission slider 401, transmission rack 402, limiting slider 403 and hinged rod 404 in the limiting mechanism 4 can perform transmission operations normally. The slideway adapted to the hinged rod 404 has a certain curvature to facilitate the hinged rod 404 to tilt at a certain angle during the transmission process.

[0034] See also Figure 3 、 Figure 4 and Figure 5One end of the transmission slider 401 is fixedly connected to a transmission rack 402, which is engaged with the transmission gear 3. The surface of the transmission rack 402 has teeth that are adapted to the transmission gear 3. When the transmission gear 3 rotates, it can drive the transmission rack 402 to slide inside the keyboard support plate 1, providing power for the sliding of the limit slider 403.

[0035] See also Figure 2 、 Figure 3 and Figure 4 A limit slider 403 is set on the outside of the transmission slider 401, and the limit slider 403 is slidably connected to the keyboard support plate 1. The two sides of the input keyboard 8 are provided with card slots adapted to the limit slider 403. When the limit slider 403 slides from the keyboard support plate 1 to engage with the card slot, the limit slider 403 will limit the input keyboard 8, so that the input keyboard 8 remains stable, thereby improving the stability of the device. When the input keyboard 8 needs to be disassembled and replaced, the limit slider 403 slides toward the inside of the keyboard support plate 1 to cancel the engaging state with the card slot. At this time, a certain input keyboard 8 can be removed from the fixing frame 2 separately, thereby improving the convenience of disassembling the input keyboard 8.

[0036] A hinge rod 404 is provided in the middle of the transmission slider 401 and the limit slider 403. The outer surfaces of the transmission slider 401 and the limit slider 403 are respectively fixedly connected with the hinge block 1 405 and the hinge block 2 406. The two ends of the hinge rod 404 are respectively rotatably connected with the hinge block 1 405 and the hinge block 2 406. The sliding of the transmission rack 402 can drive the transmission slider 401 to slide. The sliding of the transmission slider 401 will drive the hinge rod 404 to move through the hinge block 1 405. At this time, the hinge rod 404 will drive the limit slider 403 to move through the hinge block 2 406, so that the limit slider 403 is engaged with or disengaged from the slot on the input keyboard 8, which provides convenience for disassembly and replacement of the input keyboard 8.

[0037] Working principle: When the user wants to disassemble the input keyboard 8, he turns the corresponding control knob 6. The rotation of the control knob 6 will drive the transmission gear 3 to rotate through the rotating rod 5. The rotation of the transmission gear 3 will drive the transmission rack 402 to slide under the effect of meshing. The transmission rack 402 pulls the transmission slider 401 to slide. The transmission slider 401 slides through the hinge rod 404 to pull the limit slider 403 to slide toward the inside of the keyboard support plate 1, so that the limit slider 403 cancels the card connection state with the card slot on the input keyboard 8. Then the staff can complete the disassembly of the input keyboard 8 by removing the input keyboard 8 from the fixing frame 2. When installing, just plug the input keyboard 8 into the fixing block 7 and then rotate the control knob 6 in the opposite direction.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
