[0028] The keyboard body is located between the sealing plate 3 and the lower shell 2. By pressing the keycap, the pressing link 13 can be driven to move downward. The pressing link 13 moves downward to deform the silicone sheet 32 ​​to contact the keyboard body, thereby realizing the keyboard output function.

[0029] Combination Figure 1 , Figure 2 and Figure 4 From the perspective of the embodiment, the limiting mechanism includes a lower fixing block 41 provided at the four corners of the outer peripheral edge of the lower shell 2, and an upper fixing block 42 provided at the outer peripheral edge of the upper shell 1 and corresponding to the position of the lower fixing block. The upper fixing block 42 is a cylindrical structure with a hole, and the lower fixing block 41 is a fork foot structure with an opening 43. A connecting through hole is provided at the center of the fork foot structure. The upper fixing block 42 and the lower fixing block 41 are in a fitted state when the upper shell and the lower shell are closed. A fixing rod 44 is fixedly provided in the hole of the upper fixing block 42. The fixing rod 44 passes through the connecting through hole of the lower fixing block and the through end is cylindrical (generally, the fixing rod is a cylindrical rod as a whole). The circular shape of the fixing rod 44 A limit block 45 is movably sleeved on the cylindrical end, and a torsion spring 46 is sleeved on the outer periphery of the fixing rod 44. One end of the torsion spring 46 is connected to the upper fixing block 42, and the other end is connected to the limit block 45. The limit block is strip-shaped, and when the fixing rod is located in the connecting through hole of the lower fixing block, the two ends of the strip-shaped limit block are distributed at the two ends of the diameter of the connecting through hole. The lower fixing block has a channel for the limit block to pass through on the outer periphery of the connecting through hole (that is, in addition to the opening of the fork structure, a corresponding notch is also required at the other side of the connecting through hole coaxial with the opening). When it is necessary to release the fixation, the upper shell and the lower shell can be separated by rotating the limit block to the opening of the fixing block.

[0030] In order to make the closed space between the upper and lower shells in a sealed state, the upper shell 1 and the lower shell 2 are provided with a matching annular sealing frame 5 at the inner peripheral edge, and the upper shell is installed with a rubber sealing ring 6 in the annular sealing frame. The annular sealing frame can also be further designed in a stepped manner to effectively enhance the sealing effect.

[0031] In addition to the above-mentioned functions of easy disassembly and good sealing, the notebook keyboard of this embodiment also has the functions of notebook heat dissipation and improving the safety of keyboard operation. Specifically, it is also provided with a negative pressure mechanism that can evacuate the closed space formed by the upper shell and the lower shell. The negative pressure mechanism includes a micro vacuum pump 71, model myp3701, voltage 5V, the air inlet of the micro vacuum pump is connected to an exhaust pipe 72, the other end of the exhaust pipe 72 extends into the closed space formed by the upper shell 1 and the lower shell 2; the keyboard body is connected to a data cable 74 with a USB interface 73, the USB interface is adapted to the data interface of the notebook computer, the side wall of the lower shell has a hole for the data cable to extend, the data cable 74 has a branch 75 electrically connected to the micro vacuum pump 71, the USB interface is plugged in When the data interface of the notebook computer is inserted, the notebook keyboard can work, and the micro vacuum pump 71 is started to work and generate negative pressure. The notebook keyboard also includes a card connector 76 inserted at the heat dissipation port of the notebook computer (the length of the card connector is less than the length of the heat dissipation port of the notebook computer, and the card connector is a structure similar to the common USB interface, as long as it can be adapted to the heat dissipation port and can export heat to the heat dissipation pipe), the card connector 76 is connected to the middle section of the exhaust pipe through the heat dissipation pipe 77, and the heat dissipation pipe 77 is connected to the exhaust pipe 72. When the micro vacuum pump starts working, the exhaust pipe can timely extract the air in the closed space formed by the upper and lower shells, and the heat at the heat dissipation port can be immediately discharged through the micro vacuum pump, which plays an efficient cooling role on the notebook computer. The exhaust pipe and the data cable are packed together by plastic, which not only plays a protective role but also increases the aesthetics.

[0032] The negative pressure mechanism is disposed in a housing 78 , and the card connector 76 is mounted on the housing 78 .

[0033] To ensure that the space between the upper shell 1 and the sealing plate 3 also forms a negative pressure state, the sealing plate 3 is provided with an exhaust hole 33 at the position where the exhaust pipe passes, and a branch pipe 79 is connected between the exhaust hole 33 and the exhaust pipe 72. The exhaust hole 33 is a threaded hole, and the branch pipe is threadedly connected to the exhaust hole to facilitate subsequent disassembly and maintenance.

[0034] The outer surface of the lower shell is the part in contact with the desktop, and anti-skid pads 8 are preferably provided at the four corners of the outer surface to ensure the stability of the overall placement of the keyboard.

[0035] The use process of the multifunctional notebook keyboard of this embodiment is as follows: connect the card connector to the heat dissipation port of the notebook computer, connect the USB interface to the notebook computer, and the micro vacuum pump starts working. The exhaust pipe performs suction operation on the space formed between the upper shell and the sealing plate, and between the sealing plate and the lower shell. During the suction process, the heat dissipation pipe conducts heat generated by the notebook computer, and at the same time, the upper shell and the lower shell are in a negative pressure state, and the rubber sealing frame between the upper shell and the lower shell is tightly adsorbed. In addition, because the upper shell and the sealing plate are in a negative pressure state, the annular sealing ring, the pressing sealing sheet and the annular connecting block are tightly against the lower end surface of the groove, and the tightness is ensured without affecting the keyboard function. Moreover, because the closed space of the upper shell and the lower shell is highly sealed, even if water is spilled on the notebook keyboard, it will not cause any impact on the keyboard body, and it only needs to be naturally dried.

[0036] Obviously, the above embodiments are merely examples for clearly illustrating the technical solutions of the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, 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.
