[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1-12 , Figures 19-21 As shown, this utility model embodiment provides a keyboard with a mortise and tenon structure, including a bottom shell, a key core mechanism 1 disposed within the bottom shell, and a keycap assembly 2 disposed on the key core mechanism; the bottom shell includes a bottom plate 3, a left end plate 4 and a right end plate 5 respectively disposed at the left and right ends of the bottom plate, and a front side plate 6 and a rear side plate 7 respectively disposed on the front and rear sides of the bottom plate; the two ends of the left end plate 4 are respectively connected to the left ends of the front side plate 6 and the rear side plate 7 through a first mortise and tenon structure 8, that is, the two ends of the left end plate 4 are respectively connected to the left ends of the front side plate 6 and the left ends of the rear side plate 7 through a first mortise and tenon structure 8; the two ends of the right end plate 5 are respectively connected to the right ends of the front side plate 6 and the rear side plate 7 through a second mortise and tenon structure 9; the front side plate 6 and the rear side plate 7 are respectively connected to the front and rear sides of the bottom plate through a third mortise and tenon structure 10 and a fourth mortise and tenon structure 11.

[0039] In this embodiment, as Figure 2 As shown, the key core mechanism 1 includes a PCBA 101, a core 102, a fixing plate 103, a satellite axis group 104, and a key axis 105 stacked together. The above components are assembled into the key core mechanism 1 by a Gasket structure. The key core mechanism 1 and the keycap group 2 are both made using existing technology, and will not be described in detail in this embodiment.

[0040] like Figures 3-7As shown, the first mortise and tenon structure 8 includes two first tenons 801 respectively located in the two ends of the left end plate 4 and arranged laterally, two first mortises 802 respectively located in the left ends of the front side plate 6 and the rear side plate 7 and arranged laterally, and two movable pins 803; the two first tenons are respectively embedded in the two first mortises to form a first tenon joint assembly, and the two movable pins pass vertically through the two first tenon joint assemblies to connect the first tenons 801 and the first mortises 802 together.

[0041] like Figure 7 As shown, the left ends of the front side plate 6 and the rear side plate 7 are provided with a first upper plate 8a and a first lower plate 8b that are parallel to each other; the first tenon 802 is formed between the first upper plate 8a and the first lower plate 8b; the first upper plate 8a is provided with a positioning through hole 8c, and the first lower plate 8b is provided with a recessed hole 8d, and the positioning through hole and the recessed hole are aligned with each other so that the movable pin 803 can be inserted.

[0042] like Figures 8-9 , Figures 16-18 As shown, the movable pin 803 includes a pin post 803a with a pin handle, and a spring plate assembly whose upper end is engaged with the lower end of the pin post; the spring plate assembly includes an elastic element 803b with an opening at the upper end, and a spring 803c whose upper end is connected to the bottom surface of the elastic element; the elastic element is integrally formed from an elastic element base plate 8031b and two elastic sheets whose lower ends are respectively connected to the two side edges of the elastic element base plate; the opening of the elastic element is located between the upper ends of the two elastic sheets.

[0043] like Figures 16-18 As shown, the lower section of the pin 803a is inserted into the elastic element 803b. The inner walls on both sides of the opening of the elastic element are in contact with the outer wall of the pin, and the opening of the elastic element is compressed on both sides. That is, after assembly, the pin and the opening of the elastic element are in an interference fit. The lower end face of the pin is in contact with the base plate 8031b of the elastic element. It also includes a screw 803d with a nail head. The upper end of the screw passes vertically through the base plate of the elastic element and is fixedly connected to the lower end of the pin 803a. The nail head is located inside the spring, thereby fixing the elastic element 803b and the spring 803c together to form a spring assembly.

[0044] Specifically, such as Figure 9 As shown, each elastic sheet is integrally formed from a top elastic sheet 8032b, an upper inclined plate 8033b, and a lower inclined plate 8034b; the lower edge of the upper inclined plate and the upper edge of the lower inclined plate combine to form a joint 8035b; the opening is located between the two top elastic sheets; the distance between the two upper inclined plates 8033b gradually increases from top to bottom, reaching its maximum value between the two joints 8035b; the distance between the two lower inclined plates 8034b gradually decreases from top to bottom; the width of the opening is less than the distance between the two joints.

[0045] like Figure 14 , Figure 18 As shown, the first latch 801 has a through hole 801a for the movable pin 803 to pass through vertically; the two corners of the lower opening of the through hole are in contact with the surfaces of the two upper inclined plates 8033b respectively. When the spring 803c presses the elastic sheet upward, the two upper inclined plates are blocked by the two corners of the lower opening of the through hole, preventing the movable pin 803 from coming out.

[0046] like Figures 10-12 As shown, in this embodiment, to save costs and simplify the design, the structure of the second mortise and tenon structure 9 is the same as that of the first mortise and tenon structure 8. The structure of the first mortise and tenon structure 8 has been described in detail herein; by referring to this description and the corresponding accompanying drawings, the structure of the second mortise and tenon structure 9 can be fully understood, therefore, it will not be described again here.

[0047] like Figures 19-21 As shown, the third mortise and tenon structure 10 includes a front sliding groove 1001 disposed within the front side plate 6 along its length, and a front sliding rail 1002 disposed at the front edge of the upper surface of the base plate 3, with its outer edge protruding laterally from the front side of the base plate; the front sliding rail is disposed along the length of the base plate and is integrally formed with the base plate; the outer edge of the front sliding rail is embedded in the front sliding groove 1001. After assembly, the upper surface, front surface, and lower surface of the front sliding rail 1002 are respectively fitted to the upper surface, front surface, and lower surface of the front sliding groove 1001.

[0048] like Figures 19-21 As shown, the fourth tenon structure 11 includes a rear sliding groove 1101 disposed within the rear side plate 7 along its length, and a rear sliding rail 1102 disposed at the rear edge of the upper surface of the base plate 3, with its outer edge laterally protruding from the rear side of the base plate; the rear sliding rail is disposed along the length of the base plate and is integrally formed with the base plate; the outer edge of the rear sliding rail is embedded in the rear sliding groove 1101; after assembly, the base plate 3 is fixed between the left end plate 4 and the right end plate 5, so the base plate does not need to be fixed by other fasteners. After assembly, the upper surface, rear surface, and lower surface of the rear sliding rail 1102 are respectively fitted with the upper surface, rear surface, and lower surface of the rear sliding groove 1101.

[0049] like Figures 13-14 As shown, both ends of the front side plate 6 and the rear side plate 7 are provided with positioning through holes 8c. During assembly, the four movable pins 803 are inserted through the four positioning through holes 8c respectively. When installing the movable pins, press the pin handle of the pin post 803a, and the movable pin moves downward under force. Its lower end passes through the first upper plate 8a, the first latch 801, and the first lower plate 8b in sequence until the lower end of the spring 803c enters the recessed hole 8d in the first lower plate 8b and contacts the bottom surface of the recessed hole. Continuing to press down causes the spring to be compressed. When the pin handle of the pin post 803a is released, the spring 803c returns to its original position and generates an upward elastic force, which tends to push the movable pin out of the bottom shell.

[0050] During the reset process of spring 803c, when the elastic sheet is pressed upward, the two upper inclined plates 8033b are blocked by the two corners of the lower opening of the perforation 801a, preventing the movable pin 803 from coming out.

[0051] In the above description, it should be noted that the terms "installation", "connection", "connection" and other related terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; "set at" should be understood as "installed at" or "set at", including installation methods such as fixed installation and movable installation.

[0052] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
