The present invention relates to the technical field of keyboards, and specifically, to a pull-out keyboard assembly.
With rapid development of the computer industry, various high-end electronic products have emerged substantially, especially, tablet computers, which are generally recognized and favored by plenty of consumers by virtue of their characteristics such as compact structures, comfortableness, simple operation and convenience in use. In the prior art, the tablet computers generally adopt embedded keyboards, or in other words, keyboard functions are implemented by users through operations on touchscreens, causing disadvantages such as inconvenience in use and unsatisfactory operation effects.
The patent with the publication number CN114461082A provides a wireless keyboard for a tablet computer, including: a first damped rotating shaft; a support plate and a keyboard bottom plate, where the support plate is rotatably connected with the keyboard bottom plate through the first damped rotating shaft; and a support block, where when the wireless keyboard is closed, the support block is on one side, farther away from the keyboard bottom plate, of the first damped rotating shaft, and the support block can come into contact with a placement surface when the first damped rotating shaft is rotated, so that the keyboard bottom plate is obliquely arranged relative to the placement surface. Although the technical solution can improve viewing experience for the screen and improve comfort of the users during typing with both hands, it is inconvenient for the users to use keys on an upper part of the keyboard and consequently, user experience is affected because the keyboard is fixed to a bracket and a bottom of the tablet computer is relatively close to the keys on the upper part of the keyboard when the tablet computer is placed on the bracket. Therefore, a pull-out keyboard assembly is provided to resolve the problem of poor user experience in the existing tablet keyboard with a rotating shaft bracket.
One of objectives of the present invention is to provide a pull-out keyboard assembly, to resolve a problem of poor user experience of existing tablet keyboards with rotating shaft brackets.
The pull-out keyboard assembly in the present invention can be implemented via the following technical solutions:
The pull-out keyboard assembly in the present invention includes a base bracket mechanism, provided with sliding grooves at two opposite ends respectively; and a keyboard mechanism whose two ends are respectively movably arranged in corresponding sliding grooves, where
In an embodiment, the base bracket mechanism further includes: a base body, where two sliding grooves are respectively arranged at two opposite ends of the base body; a rotating shaft bracket assembly movably arranged on the base body; at least one restraint block fixedly arranged on the base body; and at least one first magnetic member fixedly arranged on the base body.
In an embodiment, the base body is separately provided with at least one first accommodating groove and at least one accommodating cavity, at least one first magnetic member is fixedly arranged in the corresponding first accommodating groove, and at least one restraint block is fixedly arranged in a corresponding accommodating cavity.
In an embodiment, the rotating shaft bracket assembly includes a connecting plate, movably arranged on the base body through a first rotating shaft; and a bracket movably arranged on the connecting plate through a second rotating shaft.
In an embodiment, the first rotating shaft and the second rotating shaft are both damped rotating shafts.
In an embodiment, the keyboard mechanism includes: a keyboard assembly with two ends respectively movably arranged in corresponding sliding grooves; and multiple ball assemblies that are respectively arranged on opposite sides of the keyboard assembly and that can come into contact with inner walls of the sliding grooves.
In an embodiment, the keyboard assembly further includes a keyboard body and a keyboard bottom plate fixedly arranged on the keyboard body; and at least one restraint magnetic set is fixedly arranged on an outer or inner side of the keyboard bottom plate.
In an embodiment, a restraint cavity is arranged at a position, corresponding to the restraint block, on the outer side of the keyboard bottom plate and the restraint block is movably arranged in the corresponding restraint cavity.
In an embodiment, the ball assembly includes a support frame, fixedly arranged on a side of the keyboard assembly; and at least one ball body that is movably arranged on the support frame and that comes into rolling contact with the inner wall of the sliding groove.
The pull-out keyboard assembly in the present invention further includes a protective housing, where the protective housing is arranged on the base bracket mechanism.
Compared with the prior art, the pull-out keyboard assembly in the present invention has the following beneficial effects:
Based on the pull-out keyboard assembly in the present invention, the multiple second magnetic members respectively mutually attract the corresponding first magnetic members, to implement fixation at different relative positions of the keyboard mechanism and the base bracket mechanism, thereby effectively resolving the problem that the existing tablet keyboard with the rotating shaft bracket causes poor user experience. The multiple ball assemblies are arranged on two sides of the keyboard assembly, and the ball assemblies come into rolling contact with the sliding grooves, so that the keyboard assembly is moved relative to the base bracket mechanism more conveniently with smaller force. In addition, the restraint block and the restraint cavity are fitted, which can effectively prevent the keyboard mechanism from falling off the base bracket mechanism, so that relative positions of the keyboard assembly and the base bracket mechanism can be adjusted in limited movement space.

It should be noted that a specific working process of the pull-out keyboard assembly in the present invention is as follows: When the relative positions of the keyboard assembly 21 and the base body 11 need to be adjusted, the keyboard assembly 21 is pushed and pulled with great force, so that the keyboard assembly 21 moves in the sliding groove 111. When the keyboard assembly is in place after pushing and pulling, the relative positions of the keyboard assembly 21 and the base body 11 are fixed through magnetic attraction force of the first magnetic member 13 and the corresponding second magnetic member 2131. Because the multiple ball assemblies 23 are arranged on both sides of the keyboard assembly 21, the keyboard assembly 21 is moved relative to the base body 11 more conveniently with smaller force, and the restraint block 14 is fitted with the restraint cavity 2122, so that the keyboard mechanism 20 can be effectively prevented from falling off the base body 11, thereby ensuring that the relative positions of the keyboard assembly 21 and the base body 11 are adjusted in limited movement space.
Technical features in the foregoing embodiments can be randomly combined. For brevity, not all possible combinations of the technical features in the embodiments are described. However, so long as the combinations of these technical features are not contradictory, the combinations should be considered as falling within the range recorded in this specification.
