Description

Technical Field

[0001] The present application relates to the field of keyboard technology, and in particular to a soft-spring and quick-release keyboard. Background Art

[0002] A keyboard is a device for inputting commands and data to operate computer equipment. A mechanical keyboard is one type of keyboard. Structurally, each key of a mechanical keyboard has a separate microswitch to control its closure. This microswitch is also called an axis. Since each key is composed of an independent microswitch, the key has a strong sense of segmentation, which will produce a special feel. Therefore, mechanical keyboards are more popular among users who have special needs for hand feel.

[0003] Usually, the structure of a mechanical keyboard includes a keycap, a shaft, a fixing plate, a PCB board and a bottom cover. The keycap is installed on the shaft, the shaft is installed on the fixing plate, the bottom of the shaft is connected to the PCB board, and the fixing plate is fixedly connected to the bottom cover. When in use, the user presses the keycap so that the keycap presses the shaft to trigger the PCB board, thereby realizing the input of instructions and data. Since the fixing plate, PCB board and bottom cover are usually connected by hard materials, the fixing plate will also be subjected to downward force during repeated key pressing, which may cause problems such as wear and noise. At present, there are also keyboards that use soft materials to achieve soft-elastic connection, but the soft-elastic structure is relatively simple and cannot adapt to the usage habits of different users. It is also difficult to replace and repair after being damaged after long-term use, thus affecting the durability of the keyboard and the user's experience. Utility Model Content

DETAILED DESCRIPTION

[0053] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0054] Usually when a mechanical keyboard is in use, the user presses the keycap so that the keycap presses the shaft to trigger the PCB board, thereby realizing the input of commands and data. Since the fixed plate, PCB board and bottom cover are usually connected by hard materials, the fixed plate will also be subjected to downward force during the process of repeatedly pressing the keys, which may cause problems such as wear and noise. Currently, there are also keyboards that use soft materials to achieve soft-elastic connections, but the soft-elastic structure is relatively simple and cannot adapt to the usage habits of different users. It is also difficult to replace and repair after being damaged after long-term use, which affects the durability of the keyboard and the user experience. Therefore, the embodiment of the present application provides a soft-elastic and quick-release keyboard, with reference to Figure 1 , Figure 2 and Figure 3 , including a top cover 1, a fixing plate 2, a PCB board 3, a bottom plate 4 and a bottom cover 5 that are mutually clamped, and also including a plurality of keys 6 installed on the fixing plate 2, the bottoms of the plurality of keys 6 are connected to the PCB board 3, the keys 6 include keycaps and shafts, the top cover 1, the bottom cover 5 and the keycaps constitute the external structure of the keyboard, and the fixing plate 2, the PCB board 3, the bottom plate 4 and the shaft constitute the internal structure of the keyboard. The top cover 1, the PCB board 3 and the bottom plate 4 are connected through a plurality of magnetic suspension components 7, the top cover 1 and the bottom plate 4 are clamped through a plurality of leaf spring components 8, the PCB board 3 and the bottom plate 4 are connected through a plurality of elastic connectors 9, and the PCB board 3 and the bottom plate 4 are also connected through a plurality of springs 10. In the specific implementation process, the elastic connector 9 is a silicone connector.

[0055] The implementation principle of the embodiment of the present application is: the PCB board 3 and the bottom plate 4 are connected by the magnetic levitation component 7 and the elastic connector 9, and the leaf spring component 8 connects the top cover 1 and the bottom plate 4, so that three different soft-elastic connections can be realized at the same time, wherein the magnetic levitation component 7 is a magnetic levitation soft-elastic connection, the leaf spring component 8 is a leaf spring soft-elastic connection, the elastic connector 9 is a silicone soft-elastic connection, and the spring 10 is a spring soft-elastic connection, so that the keyboard is soft-elasticly connected as a whole, which weakens the vibration transmitted to the PCB board 3 by the fixed plate 2 when pressing the button 6 during use, and reduces the wear and noise caused by the contact between the fixed plate 2 and the PCB board 3. At the same time, since the top cover 1, the fixed plate 2, the PCB board 3, the bottom plate 4 and the bottom cover 5 are mutually snap-connected, it is convenient for quick disassembly and assembly, thereby improving the durability of the keyboard and the convenience of user use.

[0056] like Figure 1 and Figure 2 As shown, the keyboard of the embodiment of the present application further includes a knob 101 and an LED assembly 102, and the bottoms of the knob 101 and the LED assembly 102 are connected to the PCB board 3. The knob 101 is used to adjust the settings of the keyboard, and the LED assembly 102 is used to reflect the current settings to improve the practicality of the keyboard.

[0057] like Figure 4 , Figure 5 and Figure 6 As shown, the magnetic suspension assembly 7 of the embodiment of the present application includes a first magnetic suspension part 71 and a second magnetic suspension part 72. The two ends of the first magnetic suspension part 71 are clamped with the PCB board 3, and the bottom of the first magnetic suspension part 71 is provided with a first magnet 711. The bottom of the second magnetic suspension part 72 is fixed to the bottom plate 4, and the top of the second magnetic suspension part 72 is provided with a second magnet 721. The same magnetic poles of the first magnet 711 and the second magnet 721 are opposite, and magnetic suspension is achieved by the repulsion of the same magnetic poles. Two clamping blocks 31 are provided at the clamping points between the PCB board 3 and the two ends of the first magnetic suspension part 71, and the clamping blocks 31 are provided with first clamping holes 311. The two ends of the first magnetic suspension part 71 extend downward to form two first clamping parts 712, and the first clamping parts 712 are inserted into the first clamping holes 311 of the clamping blocks 31, so that the PCB board 3 is clamped with the first magnetic suspension part 71.

[0058] In the specific implementation process, since magnetic levitation utilizes the principle that like magnetic fields repel each other, by controlling the size and direction of the repulsive force so that the size of the repulsive force and the gravity are equal and the direction is opposite, the first magnet located above is suspended in the air. Therefore, the first magnet 711 and the second magnet 721 of the embodiment of the present application are arranged relative to each other with the same name, so that a repulsive force is generated between the first magnet 711 and the second magnet 721. When the keycap is pressed during the use of the keyboard, the repulsive force of the magnetic levitation component 7 prevents the PCB board from contacting the base when it is pressed, causing wear or noise.

[0059] like Figure 3 and Figure 7 As shown, the bottom plate 4 is also provided with a plurality of spring mounting holes 44, the bottom of the spring 10 is mounted on the spring mounting hole 44, and the top of the spring 10 abuts against the PCB board 3. In the specific implementation process, when the user needs the spring 10 to be connected, the spring 10 can be installed on the spring mounting hole 44 to achieve the spring-type soft elastic connection between the bottom plate 4 and the PCB board 3, and when the user does not need the spring 10 to be connected, the spring 10 can be removed from the spring mounting hole 44.

[0060] like Figure 4 and Figure 7 As shown, first limiting grooves 11 are provided inwardly on both sides of the top cover 1, and both sides of the fixing plate 2 abut against the first limiting grooves 11. Second limiting grooves 12 are provided inwardly on both sides of the top cover 1, and a plurality of first grooves 121 are provided at the bottom of the second limiting grooves 12, and the top of the first magnetic suspension part 71 abuts against the inside of the first groove 121. By inserting the top of the first magnetic suspension part 71 into the first groove 121 of the top cover 1, the top of the magnetic suspension assembly 7 abuts against the top cover 1, and the first magnetic suspension part 71 is limited by the first groove 121.

[0061] like Figure 2 , Figure 6 and Figure 8 As shown, the bottom plate 4 is provided with a plurality of first connection holes 41 and second connection holes 42, the two ends of the second magnetic suspension part 72 are inserted into the first connection holes 41 by screws to be fixed, the tops of the plurality of elastic connectors 9 are in contact with the second limiting grooves 12, the middle is inserted into the second clamping hole 312 of the clamping block 31 of the PCB board 3 to be fixed to the PCB board 3, and the bottom is inserted into the second connection hole 42 to be fixed to the bottom plate 4, so that the bottom plate 4 is elastically connected to the PCB board 3 through the magnetic suspension assembly 7 and the elastic connector 9. In the specific implementation process, the material of the elastic connector 9 is a soft material such as silica gel. When the keycap is pressed during the use of the keyboard, the PCB board 3 will not contact the base when it is pressed due to the elastic connector 9. At the same time, due to the use of soft materials for connection, it will not cause wear or generate noise.

[0062] like Figure 7 , Figure 8 and Fig. 9As shown, the bottom of the second limiting groove 12 of the top cover 1 is also provided with a plurality of second grooves 122, and the bottom plate 4 is provided with a plurality of third connecting holes 43. The leaf spring assembly 8 includes a first lock buckle 81 and a second lock buckle 82 that are mutually clamped, the top of the first lock buckle 81 is fixed in the second groove 122, and the two ends of the bottom of the second lock buckle 82 are inserted into the third connecting hole 43 by screws to fix. The first lock buckle 81 includes a second clamping portion 811 extending downward, a clamping groove 821 is provided in the middle of the second lock buckle 82, and two steel balls 822 are provided on both sides of the inner side of the clamping groove 821, and the second clamping portion 811 is inserted between the two steel balls 822 to clamp the first lock buckle 81 and the second lock buckle 82. The steel ball 822 is fixed by a spring inside so that the steel ball 822 can move in the horizontal direction close to or away from the second clamping portion 811. The shape of the second clamping portion 811 is designed to be wider at the bottom and narrower at the top. During the specific implementation process, during installation, the second clamping portion 811 of the first lock buckle 81 needs to be inserted between the two steel balls 822 of the second lock buckle 82. The steel ball 822 is subjected to the pressing force from the bottom of the second clamping portion 811 to compress the spring, and the steel ball 822 moves in the direction away from the second clamping portion 811, leaving a space so that the second clamping portion 811 can be smoothly inserted into the clamping groove 821. After the steel ball 822 passes through the wider bottom of the second clamping portion 811, since the top of the second clamping portion 811 is narrower, the steel ball 822 is no longer subjected to the pressing force, and the spring recovers, and the steel ball 822 moves in the direction close to the second clamping portion 811, thereby realizing the clamping of the leaf spring assembly 8. At the same time, after the second clamping portion 811 is inserted between the two steel balls 822, there is still a certain gap from the bottom of the clamping groove 821. When the keycap is pressed during the use of the keyboard, the gap between the second clamping portion 811 and the clamping groove 821 ensures that the PCB board 3 will not be completely unable to be pressed when subjected to pressing force, thereby ensuring the user's hand feel when using the keyboard.

[0063] Since the embodiment of the present application realizes different soft-elastic connections simultaneously through four soft-elastic structures, namely, the magnetic levitation component 7, the leaf spring component 8, the elastic connector 9 and the spring 10, among which, the magnetic levitation component 7 is a magnetic levitation soft-elastic connection, the leaf spring component 8 is a leaf spring soft-elastic connection, the elastic connector 9 is a silicone soft-elastic connection, and the spring 10 is a spring soft-elastic connection, and the soft-elastic structures are all connected by quick-release structures such as snap-on, which is convenient for users to remove or replace different soft-elastic structures according to their own usage habits.

[0064] In a preferred embodiment, a light bar assembly is further provided on the outside of the bottom plate 4, and the inside of the light bar assembly is connected to the PCB board 3. The light bar assembly is controlled by the PCB board 3, and can emit light around the keyboard according to the user's customization, thereby improving the user's experience.

[0065] In a preferred embodiment, an anti-skid pad is further provided at the bottom of the bottom cover 5 to enhance the anti-skid effect when the keyboard is in use.

[0066] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
