[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0032] like Figure 1-6 The example shown is an embodiment provided by the utility model.
[0033] An embodiment of the utility model provides a foldable keyboard, comprising: a left keyboard 10, a middle keyboard 20, a right keyboard 30 and two hinge mechanisms 40. The left keyboard 10 is hinged to the left side of the middle keyboard 20 through one hinge mechanism 40, and the right keyboard 30 is hinged to the right side of the middle keyboard 20 through another hinge mechanism 40. Both the left keyboard 10 and the right keyboard 30 can be folded on the middle keyboard 20. Among them, the hinge mechanism 40 includes a left hinge 41, a middle hinge 42 and a right hinge 43, the left hinge 41 and the right hinge 43 are hinged on the left and right sides of the middle hinge 42 respectively, and the front and rear sides of the left end of the left hinge 41 and the front and rear sides of the right end of the right hinge 43 are respectively provided with rotating shafts 44, that is, there are four rotating shafts 44 on one hinge mechanism 40, and the two rotating shafts 44 corresponding to the two sides are coaxial, and relative to the position of the rotating shaft 44, the front and rear side frames of the right end of the left keyboard 10, the front and rear side frames of the left and right ends of the middle keyboard 20 and the front and rear side frames of the left end of the right keyboard 30 are respectively provided with sliding grooves 50 along the length direction of the keyboard, that is, two sliding grooves 50 are provided at the right end of the left keyboard 10, two sliding grooves 50 are respectively provided at the left and right ends of the middle keyboard 20, and two sliding grooves 50 are provided at the left end of the right keyboard 30. The total number of the sliding grooves 50 is the same as the number of the rotating shafts 44, and the position of each rotating shaft 44 corresponds one by one to the position of a sliding groove 50. Specifically, the hinge mechanism 40 near the left keyboard 10, the rotating shaft 44 on the left hinge 41 and the right hinge 43, respectively correspond to the sliding groove 50 on the left keyboard 10 and the sliding groove 50 at the left end of the middle keyboard 20 for sliding hinge connection; the hinge mechanism 40 near the right keyboard 30, the rotating shaft 44 on the left hinge 41 and the right hinge 43, respectively correspond to the sliding groove 50 at the right end of the middle keyboard 20 and the sliding groove 50 on the right keyboard 30 for sliding hinge connection.
[0034] When the left keyboard 10 is folded onto the middle keyboard 20, the left keyboard 10 and the middle keyboard 20 are first pulled apart to move them away from each other. At this time, the shaft 44 slides in the slide groove 50. The distance that the shaft 44 on the left hinge 41 slides in the slide groove 50 on the left keyboard 10, plus the distance that the shaft 44 on the right hinge 43 slides in the slide groove 50 on the middle keyboard 20, is adapted to the width of the middle hinge 42, so that the right side of the left keyboard 10 is aligned with the hinge axis between the left hinge 41 and the middle hinge 42, and the left side of the middle keyboard 20 is aligned with the hinge axis between the middle hinge 42 and the right hinge 43. The middle hinge 42 and the right hinge 43 are first folded 90°, and then the left hinge 41 and the middle hinge 42 are folded 90°. The left keyboard 10 and the right keyboard 20 are folded at 180°, so that the left hinge 41 and the right hinge 43 are parallel, and the middle hinge 42 is attached to the side wall formed after the left keyboard 10 and the right keyboard 30 are folded, so that the left keyboard 10 is folded onto the middle keyboard 20, and the middle hinge 42 can also protect the side of the folded keyboard; on the contrary, when the left keyboard 10 and the middle keyboard 20 are unfolded, the left keyboard 10 is directly flipped 180°, so that the left keyboard 10 and the middle keyboard 20 are in the same plane. In this process, the left hinge 41, the middle hinge 42 and the right hinge 43 are also flipped to the same plane, but at this time there is still a gap between the left keyboard 10 and the middle keyboard 20, and the left keyboard 10 needs to be pushed to the right to abut against the middle keyboard 20, and then it can be used normally. The folding of the right keyboard 30 is the same as that of the left keyboard 10, which will not be described here. After adopting the above-mentioned foldable keyboard, a hinge mechanism 40 with a left hinge 41, a middle hinge 42 and a right hinge 43 is set as a connecting structure between the left keyboard 10, the middle keyboard 20 and the right keyboard 30, so that when the keyboard is folded, the distance between the two folded keyboards can be controlled by setting the width of the middle hinge 42, and the key caps are not easily squeezed against each other. At the same time, the hinge shaft 44 located in the middle and lower part of the keyboard will not protrude from the upper frame of the keyboard and affect its use.
[0035] Furthermore, the sum of the lengths of two adjacent slide grooves 50 is greater than or equal to the width of the middle hinge 42, so that when the keyboard is folded, the intervals between the left keyboard 10, the middle keyboard 20 and the right keyboard 30 can be stretched to a foldable width, so that the hinge axis of the hinge mechanism 40 can be aligned with the side edges of each keyboard when folded.
[0036] Further, the front and rear edges of the left hinge 41 are respectively provided with left panels 411, the front and rear edges of the middle hinge 42 are respectively provided with middle panels 421, and the front and rear edges of the right hinge 43 are respectively provided with right panels 431. The left panels 411 and the right panels 431 on both sides form slide rails, the left panels 411 are slidably connected to the frame of the left keyboard 10, and the right panels 431 are slidably connected to the frame of the right keyboard 30, so that the left keyboard 10 and the right keyboard 30 can slide in a straight line in the corresponding slide rails. The rotating shafts 44 are respectively provided on the inner side walls of the left panels 411 and the right panels 431, and are respectively close to the ends of the left panels 411 and the right panels 431.
[0037] Furthermore, the height of the left panel 411 is less than or equal to the thickness of the left keyboard 10, the height of the middle panel 421 is less than or equal to the thickness of the middle keyboard 20, and the height of the right panel 431 is less than or equal to the thickness of the right keyboard 30, so that when the keyboard is unfolded, the heights of the left panel 411, the middle panel 421 and the right panel 431 will not exceed the upper side of the keyboard, and will not hinder the user's normal use.
[0038] Furthermore, a left notch 412 is provided on the right side of the left enclosure 411, and a right notch 432 is provided on the left side of the right enclosure 431. The shape of the left notch 412 matches the shape of the left half of the middle enclosure 421, and the shape of the right notch 432 matches the shape of the right half of the middle enclosure 421, so that after the keyboard is folded, the left notch 412 and the right notch 432 just surround the upper part of the middle enclosure 421, and the two corners of the upper part of the middle enclosure 421 are both 90°, and the inner angles of the left notch 412 and the right notch 432 are also 90°, so that the middle enclosure 421 can form a 90-degree support for the left enclosure 411 and the right enclosure 431, thereby supporting the left keyboard 10 or the right keyboard 30 to be folded parallel to the middle keyboard 20, reducing or avoiding the situation where the key caps are squeezed against each other.
[0039] Furthermore, the thicknesses of the left keyboard 10, the middle keyboard 20 and the right keyboard 30 are all equal, and the width of the middle hinge 42 is greater than or equal to twice the thickness of the middle keyboard 20, that is, the width of the middle hinge 42 is greater than or equal to the thickness of the left keyboard 10 plus the middle keyboard 20, and is also greater than or equal to the thickness of the right keyboard 30 plus the middle keyboard 20, so that when the keyboards are folded, the left keyboard 10 and the right keyboard 30 can reach a level parallel to the middle keyboard 20.
[0040] Further, the sum of the lengths of the left keyboard 10 and the right keyboard 30 is less than or equal to the length of the middle keyboard 20. Preferably, the lengths of the left keyboard 10 and the right keyboard 30 are both equal to half of the length of the middle keyboard 20.
[0041] Furthermore, a folding bracket 21 is provided at the bottom of the middle keyboard 20. The folding bracket 21 can be unfolded outward and extended from the rear side of the middle keyboard 20 to support a mobile phone or a tablet computer.
[0042] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents. Any equivalent structure made using the contents of the utility model specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the utility model.
