Embodiments for Carrying out the Invention

[0017] The present invention will be further described below in reference to the attached drawings and specific embodiments, but, assuming no conflicts, new embodiments can be formed by arbitrarily combining each embodiment or technical feature described below.

[0018] As shown in Figures 1 to 5, the Bluetooth keyboard with a tablet PC protective case according to the present invention includes a keyboard body 10, a protective case 20 for fixing and mounting a tablet PC, a rotating base 30, and a first locking member 40. The keyboard body 10 is provided with a positioning sleeve 50. The lower end of the rotating base 30 is rotatably inserted into the positioning sleeve 50 and is rotatable about a first rotation axis L1 relative to the positioning sleeve 50. The positioning sleeve 50 is provided with a plurality of fitting grooves 51 arranged circumferentially around the first rotation axis. The rotating base 30 is provided with a mounting groove 41. The first locking member 40 is movably mounted in the mounting groove 41 and is for fitting into the fitting groove 51. A first elastic element 60 is mounted in the mounting groove 41. The first elastic element 60 abuts against the first locking member 40 and provides an elastic force that promotes the movement of the first locking member 40 toward the positioning sleeve 50. A support member 70 is provided in the protective case 20. The support member 70 is rotatably mounted on the turntable 30 and is capable of rotating around a second rotation axis L2 relative to the turntable 30. The first rotation axis is a vertical axis and is perpendicular to the second rotation axis. Specifically, the central axis of the positioning sleeve 50 is formed as the first rotation axis.

[0019] When in use, the tablet computer is fixedly attached to the protective case 20. By applying a thrust, the protective case 20 is rotated around the second axis relative to the turntable 30 together with the support member 70 to open and close the protective case 20. If it is necessary to adjust the angle of the panel of the tablet computer, the protective case 20 and the turntable 30 can be pushed around the first axis, and the turntable 30 can be rotated around the first axis within the positioning sleeve 50. At this time, the first locking member 40 rotates as the turntable 30 rotates. When the turntable 30 is rotated to the corresponding angle, the first locking member 40 moves toward the positioning sleeve 50 by the elastic force of the first elastic element 60, and is fitted into the corresponding fitting groove 51 so that the protective case 20 and the tablet computer are held at the corresponding viewing angles. Therefore, the Bluetooth keyboard with a tablet computer protective case according to the present invention adopts a combined design of the keyboard body 10, the protective case 20, the turntable 30, the first locking member 40, the positioning sleeve 50 and the first elastic element 60, so that the protective case 20 rotates around the first axis together with the turntable 30, and the protective case 20 can rotate around the second axis relative to the turntable 30. Thereby, the orientation of the screen of the tablet computer fixed to the protective case 20 can be adjusted, and the flexibility of use can be enhanced. Also, when installing, the support member 70 is attached to the turntable 30 and installed on the protective case 20. Further, the turntable 30 with the first elastic element 60 and the first locking member 40 attached is attached to the positioning sleeve 50 and fitted. Therefore, the structure is relatively simple, the installation is convenient, the installation cost and installation time can be saved, and the manufacturing cost can be reduced.

[0020] In this embodiment, the end portion of the keyboard body 10 provided with the positioning sleeve 50 protrudes outward with respect to the protective case 20.

[0021] The first elastic element 60 is a first coil spring. One end of the first elastic element 60 abuts against the groove wall of the mounting groove 41, and the other end abuts against the first locking member 40.

[0022] Of course, the first elastic element 60 can also be an elastic sheet or other type of first elastic element 60, but using a first coil spring as the first elastic element 60 is the optimal embodiment of the present invention because it reduces costs and is convenient to install.

[0023] The first locking member 40 is provided with a positioning groove 43 into which the first elastic element 60 is fitted, in order to facilitate the attachment and positioning of the first elastic element 60.

[0024] The portion of the positioning sleeve 50 located between any two adjacent fitting grooves 51 is formed as a stopper portion 52 for the first locking member 40 to abut against. When the first locking member 40 moves from the fitting groove 51 to the adjacent stopper portion 52 as the turntable 30 rotates, the first locking member 40 is pressed against the stopper portion 52 and retracts into the mounting groove 41, and the first coil spring is in a compressed state. On the other hand, when the first locking member 40 moves from the stopper portion 52 to the adjacent fitting groove 51 as the turntable 30 rotates, the first coil spring elastically returns to its original position, and the first locking member 40 moves toward the positioning sleeve 50 due to the elastic force of the first coil spring and is fitted into the fitting groove 51.

[0025] The first locking member 40 is a locking pin. The locking pin has a triangular cross-section and is provided with a pin head 42 for fitting into the fitting groove 51. The shape of the fitting groove 51 matches the shape of the pin head 42. By adopting the above configuration, the insertion and removal of the first locking member 40 into and from the fitting groove 51 becomes easy.

[0026] Of course, the first locking member 40 can also be a column core, a sphere, or the like. In another preferred embodiment of the present invention, the first locking member 40 can be a wave-shaped bead. In this case, as the turntable 30 rotates, the first locking member 40 moves from the abutment portion 52 to the adjacent fitting groove 51. The wave-shaped bead is then repelled by the elastic force of the first coil spring and fitted into the corresponding fitting groove 51, colliding with the groove wall of the fitting groove 51 and producing a sound. This makes it easier for the user to understand the rotation status of the turntable 30 together with the protective case 20 based on the sound, thereby enhancing the user experience.

[0027] The support member 70 includes a support shaft 71 fixed to the protective case 20. The support shaft 71 is provided with a position restricting portion 72 and a stopper 80. The turntable 30 is provided with a connecting tab 31. The support shaft 71 is rotatably inserted into the connecting tab 31. The connecting tab 31 is sandwiched between the position restricting portion 72 and the stopper 80. The central axis of the support shaft 71 is formed as the aforementioned second rotation axis. By rotating the protective case 20 together with the support shaft 71 around the aforementioned second rotation axis relative to the connecting tab 31 of the turntable 30, the rotation angle of the protective case 20 can be adjusted around the second rotation axis. Furthermore, after the protective case 20 has rotated to a predetermined position, the frictional force between the connecting tab 31 and the position restricting part 72 and the stopper 80 (or the frictional force between the connecting tab 31 and the position restricting part 72 and the stopper 80, and the frictional force between the support shaft 71 and the connecting tab 31) holds the protective case 20 in place at the corresponding opening and closing angle.

[0028] The stopper 80 includes a fastener 81 detachably connected to the support shaft 71, and a plurality of elastic washers 82 attached to the support shaft 71 and positioned between the connecting tab 31 and the fastener 81. The stopper 80 further includes a first washer 83 and a second washer 84 attached to the support shaft 71. The first washer 83 is positioned between the connecting tab 31 and an elastic washer 82 adjacent to the connecting tab 31. The second washer 84 is positioned between the fastener 81 and an elastic washer 82 adjacent to the fastener 81.

[0029] Here, the fastener 81 may be a nut screwed onto the support shaft 71, or a retainer ring locked onto the support shaft 71, etc.

[0030] The position regulating portion 72 comprises a flange provided on the support shaft 71 and a third washer located between the flange and the connecting tab 31, making it easy to install and manufacture. Of course, the position regulating portion 72 could also be a retainer ring provided on the support shaft 71, but using the shaft shoulder and third washer for the position regulating portion 72 is the optimal embodiment of the present invention.

[0031] In this embodiment, the support member 70 is fixed to the protective case 20 and includes two support shafts 71 that are positioned opposite each other. The central axes of these two support shafts 71 overlap. The turntable 30 is provided with two connecting tabs 31 that correspond one-to-one with each of the two support shafts 71. The support shafts 71 are rotatably inserted into the corresponding connecting tabs 31, which enhances the stability when the protective case 20 rotates.

[0032] Here, the materials of the keyboard body 10 housing and protective case 20 may be set according to actual needs. In a further preferred embodiment of the present invention, the keyboard body 10 housing and protective case 20 may be set in a transparent, glittery manner. This allows the components inside the keyboard body 10 to be visible from the outside, creating a cyberpunk style and enhancing the design. Of course, various color changes, lighting flashing effects, etc., can also be applied to the keyboard body 10.

[0033] Specifically, the mounting groove 41 extends along the radial direction of the rotating base 30.

[0034] In this embodiment, the turntable 30 includes a support plate, a ring fixed to the support plate and inserted into a positioning sleeve 50, and a connecting frame fixed to the support plate. A mounting groove 41 is provided in the ring. A connecting tab 31 is provided on the connecting frame and extends upward. By adopting the above configuration, the manufacture of the turntable 30 becomes easier.

[0035] Of course, the turntable 30 can also employ other structures, but employing a combination of a support plate, a ring, and a connecting frame for the turntable 30 is the optimal embodiment of the present invention and can reduce manufacturing costs.

[0036] In a further preferred embodiment of the present invention, the keyboard body 10 is a Bluetooth keyboard body, which is connected to a tablet PC via Bluetooth wireless technology.

[0037] Figures 6 to 9 are schematic diagrams of different embodiments of the present invention, and the differences from Figure 1 are as follows.

[0038] In this embodiment, the positioning sleeve 50 is rotatably attached to the keyboard body 10. A second locking member 5 is further movably attached to the keyboard body 10. Moreover, a second coil spring 92 is provided between the second locking member 91 and the keyboard body 10. The positioning sleeve 50 is provided with an engagement slot 93 into which the second locking member 91 is fitted. When the second locking member 91 is fitted into the engagement slot 93, it is ensured that the positioning sleeve 50 is stably fixed after the protective case 20 has rotated to the correct position. The protective case 20 is provided with a projection 21, and the keyboard body 10 is provided with a groove 11 into which the projection 21 is fitted. When the protective case 20 is covered over the keyboard body 10, the projection 21 fits into the groove 11 to perform a positioning function and avoid rotational displacement phenomena caused by accidental collision of the protective case 20.

[0039] The embodiments described above are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention. Any substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required of the present invention.
