DETAILED DESCRIPTION

[0017] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a detachable keyboard with multimedia control function of the present invention comprises a bottom shell 1, a keyboard main board 2 and a plurality of key shafts 5, wherein the keyboard main board 2 is mounted on the surface of the bottom shell 1, and a plurality of cross bars 3 are mounted on the surface of the keyboard main board 2, and positioning channels are formed between the cross bars 3, and adjustment frames 11 are arranged in the positioning channels, and a plurality of key shafts 5 are arranged in the adjustment frames 11, and positioning grooves 14 are arranged on the four corners of the key shafts 5, and inner side surfaces of the adjustment frames protrude opposite to the positioning grooves 14 to form positioning portions 6, and the positioning portions 6 are inserted into the positioning grooves 14, and one end of the adjustment frames extends to the outside of the keyboard main board 2, and locking components for positioning the adjustment frames are installed.

[0021] In the present embodiment, a first contact 10 is embeddedly installed at each key shaft 5 of the keyboard main board 2, and a slot is provided on the surface of the first contact 10. A plurality of second contacts 16 are installed on one end surface of the key shaft 5 facing the keyboard main board 2, and one end of the second contact 16 is inserted into the slot. The outer surfaces of the slot and the second contact 16 are both hemispherical structures. The hemispherical structure can smoothly move the second contact out of or insert into the slot.

[0022] In this embodiment, the locking components include a fixing seat 7 and a positioning column 8. The fixing seat 7 is installed on the bottom shell 1. A groove is provided on the fixing seat 7. A positioning hole 15 is provided at one end of the adjustment frame opposite to the fixing seat 7. One end of the positioning column 8 is inserted into the positioning hole 15, and the other end is inserted into the groove. A compression spring is installed, and the other end of the compression spring is installed on the inner wall surface of the groove.

[0023] In this embodiment, slide grooves 9 are provided on both sides of the adjustment frame 11, and sliding bars 13 are installed on the sides of the cross bar 3 facing the adjustment frame. The sliding bars 13 are slidably set in the slide grooves 9. The adjustment frame can be positioned through the slide grooves and the sliding bars so that the second contact on the key shaft can be in close contact with the first contact on the keyboard motherboard to ensure conductivity between the key shaft and the keyboard motherboard.

[0024] In this embodiment, a longitudinal rod 4 is installed at one end of the plurality of transverse rods 3, and a side surface of the longitudinal rod 4 is arranged to abut against the end surface of the adjustment frame. The adjustment frame can be positioned laterally by the longitudinal rod and the positioning column to avoid displacement that affects use.

[0025] In this embodiment, a plurality of buttons 12 for controlling volume up / down keys and play / pause are installed on one of the crossbars 3, and the user can customize the functions of these buttons through the buttons to meet different usage requirements.

[0026] In this embodiment, the width of the key shaft 5 matches the width of the inner cavity of the adjustment frame, thereby avoiding the movement of the key shaft and increasing the stability after installation.

[0027] In this embodiment, the adjustment frames are made of high-strength plastic materials, which avoids conductivity and increases firmness, and can better position the key shaft.

[0028] In this embodiment, scales corresponding to the key shafts 5 are provided on the crossbars 3, and the alignment position of each key shaft can be known through the scales to ensure the normal use of the key shafts.

[0029] After any key shaft fails, the corresponding positioning frame is found and the positioning column is squeezed to move the positioning column out of the positioning hole. After losing the obstruction of the positioning column, the corresponding adjustment frame can be directly held and pulled outward. The movement of the adjustment frame drives a row of key shafts. By pulling the adjustment frame, the key shaft on the side can be temporarily replaced by the key shaft at the failed position to perform temporary input, ensuring emergency use. Since the cross bar is provided with a scale, the position of the key shaft after movement can be known through the scale until the second contact on the key shaft can be inserted into the card slot of the first contact to complete the conduction between the key shaft and the keyboard body, and the moved key shaft and the adjustment frame can be positioned by card connection. After use, the adjustment frame can be pushed back again. After the adjustment frame returns to its position, the positioning column can be inserted into the positioning hole again by the rebound of the compression spring to complete the positioning of the adjustment frame. When disassembling, the positioning column is squeezed again and the adjustment frame is pulled outward. Through the adjustment frame, all the key shafts in this row can be pulled outward. After losing the obstruction of the keyboard motherboard, the key shafts can directly fall downward. When installing, the keyboard can be turned over and the new key shaft is inserted into the adjustment frame until the positioning part enters the positioning groove. After the adjustment frame is pushed back into the interior of the positioning channel, the second contact of the key shaft can contact the first contact again.

[0030] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
