Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, specifically a split-type folding keyboard. Background Technology

[0002] In today's era of ubiquitous digital devices, keyboards, as a core input tool for human-computer interaction, are widely used in various devices such as computers, tablets, and smart terminals. With the surge in demand for mobile office and portable entertainment scenarios, users have placed higher demands on keyboard portability. Traditional all-in-one keyboards are bulky and inconvenient to carry, failing to meet users' needs for input anytime, anywhere, such as during travel or outdoors. Against this backdrop, the split-type folding keyboard has emerged. By designing the keyboard body as a detachable and foldable structure, the split-type folding keyboard significantly reduces its size while maintaining basic input functions, allowing it to easily fit into backpacks, pockets, and other small spaces for convenient carrying. At the same time, the split design also provides more possibilities for keyboard usage; users can adjust the keyboard layout and form according to their actual needs, improving input comfort and efficiency. Therefore, the split-type folding keyboard has become an ideal solution to meet modern users' needs for portable and efficient input.

[0003] Traditional split-type folding keyboard technology still has many shortcomings. In terms of structural design, many traditional split-type folding keyboards have complex folding mechanisms and numerous components. This not only increases the manufacturing cost but also results in a heavier keyboard, further reducing its portability. Moreover, complex folding mechanisms are prone to wear and loosening, affecting the keyboard's lifespan. Regarding connection stability, traditional technologies often struggle to ensure a stable connection between the split sections in both folded and unfolded states. In the folded state, gaps may exist between the split sections, making them susceptible to impacts and pressure from external objects, potentially causing damage. Therefore, we propose a split-type folding keyboard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a split-type folding keyboard, which solves the aforementioned problems.

[0026] Working principle: First, the connecting shaft of connector 4 and connector seat 2 is movably connected, achieving the rotational folding effect of the second folding cover 3 relative to the folding cover 1. When the user needs to fold the keyboard, they hold the second folding cover 3 and apply external force. The second folding cover 3 rotates around the connecting shaft of connector 4 and connector seat 2, gradually approaching the folding cover 1, achieving the initial folding action. During the folding process, the locking head 10, the arc-shaped locking ring 6, and the second arc-shaped locking ring 7 engage and cooperate to achieve the switching effect of locking and unlocking. When the second folding cover 3 rotates to a position close to fitting with the folding cover 1, the locking head 10 enters the inner wall position of the arc-shaped locking ring 6 and the second arc-shaped locking ring 7. At this time, the user can manually operate the arc-shaped locking ring 6 and the second arc-shaped locking ring 7. Since the bottom side of the arc-shaped locking ring 6 and the bottom side of the second arc-shaped locking ring 7 are movably connected, and the top of the arc-shaped locking ring 6 is connected to the fixed plate 5 through the spring 8, and the top of the second arc-shaped locking ring 7 is connected to the fixed plate 5 through the second spring 9, the user applies external force to open the arc-shaped locking ring 6 and the second arc-shaped locking ring 7. After the locking head 10 is fully inserted, the user releases the external force. Under the elastic force of the spring 8 and the second spring 9, the arc-shaped locking ring 6 and the second arc-shaped locking ring 7 return to their original state, locking the locking head 10 inside, thus locking the keyboard. Conversely, applying external force to open the arc-shaped locking ring 6 and the second arc-shaped locking ring 7 unlocks the keyboard, allowing it to unfold. The parallel design of the arc-shaped groove 11 and the second arc-shaped groove 12 achieves a comfortable grip effect for the user during operation. When the user unfolds the keyboard, they can easily open it by pressing their fingers into the arc-shaped groove 11 or the second arc-shaped groove 12, improving the user experience. The left-side split keyboard 13 and the right-side split keyboard 14 are respectively located at the bottom of the inner wall of the folding cover 1 and the second folding cover 3. Through linkage with the aforementioned folding and locking structure, the integration and portability of the split keyboard are achieved. When the keyboard is unfolded, the left-side split keyboard 13 and the right-side split keyboard 14 together form a complete keyboard layout for normal user input.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
