[0016] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0017] Please refer to Figure 1-3A keyboard bottom plate detection device comprises a base 1, two vertical plates 2 are symmetrically arranged on the upper surface of the base 1, a keyboard 10 is arranged between the two vertical plates 2 on the upper surface of the base 1, a plurality of keys 11 arranged in rows are arranged on the keyboard 10, slide grooves 3 are respectively arranged on the two vertical plates 2, a detection mechanism is arranged between the two vertical plates 2, and both ends of the detection structure can move horizontally in the slide grooves 3 for detecting the keys 11 in each row.

[0018] The detection mechanism includes a moving frame 4, a holding rod 7 and a holding plate 8. The moving frame 4 is arranged on the inner side of the two vertical plates 2. The moving frame 4 can move horizontally in the slide groove 3. A slot hole 41 is arranged in the moving frame 4. A compression spring 42 is arranged in the slot hole 41. The bottom of the compression spring 2 is fixed to the bottom surface of the slot hole 41. The top of the compression spring 42 is fixedly connected to the end of the holding rod 7. The holding plate 8 is vertically fixed directly below the holding rod 7. The holding rod 7 and the holding plate 8 are integrated. When the holding rod 7 and the holding plate 8 move downward, they touch the key 11 on the keyboard 10.

[0019] As a preferred solution, a fixed rod 6 is also provided on the outer side of the movable frame 4, and the fixed rod 6 passes through the vertical plate 2 at the slide groove 3 and is fixedly connected to the movable frame 4. A second limiting plate 9 is provided on the fixed rod 6 to prevent the holding rod 7 from tilting, thereby ensuring that the holding rod 7 and the holding plate 8 are always in a horizontal state.

[0020] As a preferred solution, a first limiting plate 5 is further provided on the inner side of the two vertical plates 2, and the distance between the two first limiting plates 5 is less than the length of the holding plate 8, and the length of the vertical plate 2 is greater than the width of the keyboard 10; when the holding rod 7 and the holding plate 8 are pressed, the holding plate 8 is located directly above the key 11, ensuring that the holding plate 8 holds the entire row of keys 11 when moving downward.

[0021] When the key 11 is normal, after pressing the holding rod 7 and the holding plate 8, the bottom of the holding plate 8 touches the first limit plate 5; when the key 11 cannot be pressed or cannot be pressed to the use position, a gap is left between the holding plate 8 and the first limit plate 5, proving that the keys 11 in this row cannot be pressed or are not pressed sufficiently, and then they are checked one by one; the keys 11 on the keyboard 10 can be screened in rows to increase detection efficiency.

[0022] Among them, the length of the slide groove 3 is greater than the width of the keyboard 10, and the keyboard 10 is arranged in the middle of the base 1, ensuring that the outermost keys 11 on the keyboard 10 can also be pressed and detected. During the pressing detection, it is only necessary to move the movable frame 4, the holding rod 7 and the holding plate 8 in the slide groove 3.

[0023] When the novel keyboard bottom plate detection device is used, the keyboard 10 is first fixed in the middle of the base 1, and then the moving frame 4, the holding rod 7 and the holding plate 8 are moved to the top of the first row of keys 11, and then the holding rod 7 and the holding plate 8 are pressed downward, at which time the holding rod 7 compresses the compression spring 42, and the holding rod 7 and the holding plate 8 move downward;

[0024] When the bottom of the holding plate 8 touches the first limit plate 5, it proves that the keys 11 of the row can be pressed and used normally. When there is a gap between the holding plate 8 and the first limit plate 5, it proves that one or more keys 11 of the row cannot be pressed and used normally. Then the keys 11 that cannot be used are selected for debugging or rectification. After the holding test, the compression spring 42 returns to its original position.

[0025] After the first row of keys 11 are detected, the movable frame 4, the holding rod 7 and the holding plate 8 are moved to detect the keys 11 on the keyboard 10 row by row, thereby increasing the detection efficiency and being simple and convenient to use.

[0026] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0027] Obviously, the above embodiments are only examples for the purpose of clear explanation and are not intended to be construed as examples.

[0028] Limitation of implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. However, obvious changes or modifications derived from this are still within the scope of protection of the invention.
