[0002] With the development of the computer industry, different types of keyboards have emerged as the main input devices for computers. Existing computer keyboards mainly include rubber membrane keyboards and mechanical keyboards. Among them, membrane keyboards are more common, mainly because they are relatively cheap. However, their operating performance is still quite different from that of mechanical keyboards. Both membrane keyboards and mechanical keyboards are generally aimed at right-handed users. Keyboards for left-handed users are still relatively rare and generally need to be customized. How to provide a left-handed keyboard for left-handed users is a research and development direction. Specially designed left-handed keyboards are designed to improve the user experience of left-handed users. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1: Reference Figure 1-5 A left-handed keyboard for the computing industry includes a keyboard body 1, an expansion board 2, a circuit board 3, a key assembly 4, and a connection assembly 5. The expansion board 2 is fixedly mounted on one side of the keyboard body 1. The circuit board 3 is disposed inside the keyboard body 1 and extends into the interior of the expansion board 2. The connection assembly 5 is disposed on both the keyboard body 1 and the expansion board 2, and the connection assembly 5 is electrically connected to the circuit board 3. The keyboard body 1 is also provided with a plurality of key assemblies 4, each of which is assembled with the connection assembly 5. The key assembly 4 and the connection assembly 5 cooperate with each other. When the key assembly 4 is actuated, the connection assembly 5 will connect with the circuit board 3, thereby completing the signal transmission of the circuit board 3, which is suitable for left-handed users.

[0026] A cover plate 7 is provided on each connecting component 5 on the expansion board 2 through a hinge 6. The cover plate 7 can prevent dust and other impurities from entering when not in use.

[0027] Reference Figure 5The key assembly 4 includes a keycap 40, a connecting rod 41, a connecting plate 42, a slider 43, a contact plate 44, a contact rod 45 and a telescopic sleeve 46. The bottom of the keycap 40 is fixedly connected to the upper part of the connecting rod 41. The connecting rod 41 is located below the keycap 40 and passes through the connecting plate 42. The connecting rod 41 and the keycap 40 are fixedly connected by a telescopic sleeve 46. The connecting rod 41 is also fixedly connected to the slider 43, and the slider 43 is located below the connecting plate 42. The slider 43 is also fixedly connected to the contact plate 44. Two contact rods 45 are set at the bottom of the contact plate 44.

[0028] Normal keystroke process:

[0029] The key assembly 4 and the connecting assembly 5 are matched together. When using a specific key, you only need to press the keycap 40. The key 40 drives the connecting rod 41, and the return spring 51 is squeezed through the retaining ring 8 on the inner connecting rod 41. The connecting rod 41 drives the slider 43 to move during the downward movement. At the same time, the slider 43 drives the contact plate 44 to move downward, so that the two contact rods 45 at the bottom of the contact plate 44 are respectively extended into the contact holes 52, and the contact holes 52 are connected to the circuit board 3. When contact occurs, the electrical signal is transmitted to the contact plate 44. When the contact plate 44 contacts the contact protrusion 54, a loop is formed, so that the circuit board 3 recognizes the electrical signal and the computer performs the corresponding operation.

[0030] When disassembling the key assembly 4, which is mainly for left-handed users, the connection interface 5 on the expansion board 2 can be set to a specific function. When disassembly is required, the key assembly 4 is separated from the connection assembly 5 by fingers. When separating, the keycap 40 is first lifted up with force, and then the connecting rod 41 drives the retaining ring 8 to separate the connecting plate 42 from the groove 10, and the gasket 9 is separated from the magnetic block 12. During normal use, the magnetic block 12 in the groove 10 adsorbs the connecting plate 42 on the connecting cavity 50. The retaining ring 8 is also mounted on the connecting rod 41, and the retaining ring 8 is located below the slider 43. The retaining ring 8 can not only compress the return spring 51, but also facilitate the separation of the connecting plate 42 from the groove 10 during disassembly.

[0031] Gaskets 9 are also provided at the four corners of the lower surface of the connecting plate 42. The connecting assembly 5 includes a connecting cavity 50, a return spring 51, a contact hole 52, a top plate 53, and a contact protrusion 54. The return spring 51, the contact hole 52, the top plate 53, and the contact protrusion 54 are respectively provided inside the connecting cavity 50. The top plate 53 is vertically connected to the contact protrusion 54, and the contact hole 52 is located between the return spring 51 and the top plate 53. The contact hole 52 is mainly for facilitating contact with the contact rod 45. The top plate 53 is also connected to the circuit board 3 to transmit the electrical signal on the circuit board 3 to the contact plate 44. After the contact plate 44 contacts the contact protrusion 54, a closed circuit is formed. The contact protrusion 54 is an elastic member. A groove 10 is provided on the upper edge of the connecting cavity 50, and a plurality of circular holes 11 are provided above the groove 10. A magnetic block 12 is provided in each circular hole 11. A support plate 13 is further provided at the bottom of the expansion plate 2 , and the bottom surface of the support plate 13 and the bottom surface of the keyboard body 1 are located at the same horizontal plane.

[0032] The above is only the best specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
