The utility model provides a key.

Referring to fig. 1, fig. 2 and fig. 3, in an embodiment of the present invention, the key includes a base 10, a pressing component 20, a sounding component 30 and a buffer 40; the pressing component 20 is arranged on the base 10 in a lifting manner; the sounding component 30 is arranged on the base 10 or the pressing component 20, the sounding component 30 is driven by the pressing component 20, and when the pressing component 20 is lifted relative to the base 10, the sounding component 30 collides with the base 10 and/or the pressing component 20; the buffer member 40 is disposed on one of the base 10 and the pressing member 20, and when the pressing member 20 moves up and down with respect to the base 10, the buffer member 40 can abut against the other of the base 10 and the pressing member 20.

In an embodiment of the present invention, the base 10 is mainly used for mounting and bearing the pressing component 20, the sounding component 30, and the buffer 40, and can be mounted on the keyboard body of the keyboard. Therefore, all parts of the key can be integrally formed and can be arranged on the keyboard body at one time, and the convenience of key installation is improved. The projection of the base 10 on the horizontal plane may be square, or may be circular, and the shape of the base 10 is not specifically limited in this application. In order to reduce the overall weight of the keys and make the keyboard portable, the base 10 may be made of plastic, for example: ABS, POM, PS, PMMA, PC, PET, etc. Of course, in order to prolong the service life of the key, the base 10 may be made of metal, for example: stainless steel materials, aluminum alloy materials, copper alloy materials, iron alloy materials and the like. The pressing member 20 is mainly used to implement the key function by pressing action so as to input information such as characters, symbols or numbers. The working principle can be as follows: the pressing component 20 descends to block or conduct the optical path between the optical transmitter and the optical receiver on the keyboard body of the keyboard, and at this time, the control circuit board in the keyboard body of the keyboard can detect the blocking or the conducting of the optical signal to realize the key function. The following steps can be also included: the pressing component 20 descends to abut against a contact switch on the keyboard body of the keyboard, and at the moment, a control circuit board in the keyboard body of the keyboard can detect a trigger signal of the contact switch to realize a key function. Of course, the base 10 of the key may be provided with a related light emitter, or contact switch, which is not limited in this application, and it is sufficient to ensure that the key can realize the key function. Since the principle of the key function realized by pressing the key is the prior art, it is not described in detail herein. The sounding component 30 is mainly used for colliding with the base 10 and/or the pressing component 20 when the sounding component is driven by the pressing component 20, so that the keys can give out prompting sound when in use. The buffer member 40 is mainly used to buffer the pressing member 20 when the pressing member 20 descends, so as to prevent the pressing member 20 from directly colliding with the base 10. To reduce the generation of noise and to avoid wear due to collision. When the key is not provided with the sounding member 30 but only with the buffer member 40, noise generated during the pressing of the key can be effectively reduced by the buffer member 40. The cushion member 40 may be provided on the base 10 or on the pressing unit 20, and the cushion member 40 may be positioned between the two for contact and cushion when the pressing unit 20 is lowered. And the material of this bolster 40 is rubber material or silica gel material to make bolster 40 have certain elasticity and improve buffering effect, have certain intensity again simultaneously and can be better to pressing subassembly 20 and base 10 keep apart the support, avoid taking place when being extrudeed that deformation is too big and reduced buffering effect.

The technical scheme of the utility model the button is when pressing, presses subassembly 20 through the drive and descends for base 10, can be so that sound production subassembly 30 is driven by this pressing subassembly 20 to collide mutually and send the suggestion sound with base 10 and/pressing subassembly 20. Compared with the prior art that the button cannot give out prompt sound after being pressed, the button in the scheme enables a user to timely determine whether the button is effectively pressed or not after the user presses the button. The phenomenon that the key is pressed repeatedly or is pressed neglectly is avoided, and therefore the convenience of the keyboard is improved.

Further, the pressing component 20 in the present embodiment further includes a buffer 40, and the buffer 40 can buffer the contact between the pressing component 20 and the base 10 after descending, so as to avoid direct collision between the pressing component 20 and the base 10. Therefore, the generation of noise can be reduced, the definition of the prompt sound emitted by the sound emitting component 30 is improved, and the abrasion of the pressing component 20 and the base 10 caused by direct collision can be avoided, so that the service life of the key is prolonged.

Referring to fig. 2 and 3, in an embodiment of the present invention, in a lifting direction of the pressing element 20, a mounting hole 11a is disposed on a side of the base 10 facing the pressing element 20, a partial structure of the buffer element 40 is inserted into the mounting hole 11a, and a side of the buffer element 40 away from a bottom wall of the mounting hole 11a can abut against the pressing element 20.

It can be understood that, since the strength of the base 10 is relatively high compared to the strength of the pressing member 20, the installation hole 11a is provided in the base 10 to avoid the installation hole 11a from affecting the strength of the pressing member 20. The installation hole 11a is arranged so that the assembly of the buffer member 40 can be completed by inserting part of the structure of the buffer member 40 into the installation hole 11a, and the installation efficiency of the buffer member 40 can be improved because the process is simple. Meanwhile, the installation holes 11a are also arranged so that there is no need to provide a connection structure on the buffer member 40 to install the buffer member 40 on the base 10, that is, the installation holes 11a are arranged on the base 10 to form the connection structure. The connecting structure of the buffer member 40 and the base 10 is simplified, so that the manufacturing cost can be reduced, and the influence of the arrangement of the connecting structure on the structure of the buffer member 40 can be avoided. Of course, the present invention is not limited thereto, and in other embodiments, the buffer 40 may be adhered to the base 10 by glue, or connected to the base 10 by a snap.

Referring to fig. 3, in an embodiment of the present invention, the buffer 40 includes a first segment 41 and a second segment 43; the first segment 41 is inserted into the mounting hole 11 a; the second segment 43 is connected to the side of the first segment 41 away from the bottom wall of the hole of the mounting hole 11a, the area of the cross section of the second segment 43 is larger than that of the first segment 41, at least a part of the second segment 43 is located outside the mounting hole 11a, and the side of the second segment 43 away from the first segment 41 can be abutted to the pressing component 20.

It can be understood that the arrangement that the area of the cross section of the second segment 43 is larger than that of the first segment 41 can increase the abutting area of the buffer 40 and the pressing component 20, thereby improving the buffering effect of the buffer 40 on the pressing component 20. Meanwhile, the strength of the buffer member 40 can be improved by the arrangement, so that the service life of the buffer member 40 can be prolonged. In order to improve the connection strength between the first segment body 41 and the second segment body 43, the first segment body 41 and the second segment body 43 may be integrally formed, so that the buffer member 40 can be integrally formed to improve the production efficiency of the buffer member 40.

In an embodiment of the present invention, the hole sidewall of the mounting hole 11a is provided with a supporting step 11b at the hole opening of the mounting hole 11a, and a part of the structure of the second segment 43 abuts against the supporting step 11 b.

It can be understood that the supporting step 11b is disposed to make the partial region of the side peripheral surface of the second segment 43 contact with the base 10, so as to increase the contact area between the buffer 40 and the base 10, thereby improving the stability of the installation of the buffer 40. Further, the first segment body 41 may have a gap with the hole bottom wall of the mounting hole 11 a.

In an embodiment of the present invention, the cross section of the buffer member 40 is circular, and the mounting hole 11a is adapted to the shape of the buffer member 40.

It can be understood that the cross section of the buffer member 40 is circular, so that the circumferential direction of the buffer member is consistent, and thus, the positioning in the installation direction before the installation is not needed, thereby further improving the installation efficiency of the buffer member 40. The mounting hole 11a is matched with the shape of the buffer member 40, i.e. is arranged in a circular shape, so that the generation of edge corners is avoided and the complexity of the forming of the mounting hole 11a can be reduced. The first segment 41 and the second segment 43 of the buffer member 40 may be disposed in a circular shape in cross section. Further, a gap can be formed between the bottom wall of the mounting hole 11a and the side, away from the second segment 43, of the first segment 41, so that the bottom wall of the mounting hole 11a does not need to be flat and can ensure flat and accurate mounting of the buffer member 40.

Referring to fig. 2, in an embodiment of the present invention, the base 10 is formed with four corner areas, in a lifting direction of the pressing component 20, two mounting holes 11a are disposed on one side of the base 10 facing the pressing component 20, two of the two mounting holes 11a are respectively located in the four corner areas and are corner areas arranged diagonally, the key includes two buffering components 40, a partial structure of one buffering component 40 is inserted into one mounting hole 11a, and one side of the two buffering components 40 departing from a bottom wall of the mounting hole 11a can be abutted to the pressing component 20.

It will be appreciated that the provision of two bumpers 40 may improve the cushioning effect on the pressing assembly 20. And two bolster 40 are located two corners that are diagonal setting respectively, can make the comparatively even that the cushion force of bolster 40 to pressing the subassembly 20 distributes around the center of pressing the subassembly 20 to can improve the stationarity that pressing the subassembly 20 goes up and down at the pressing in-process. Of course, the present application is not limited thereto, and in other embodiments, the base 10 may also have three or more pattern sub-holes, and the three or more pattern sub-holes are evenly spaced around the center of the base 10.

Referring to fig. 2, in an embodiment of the present invention, the sounding component 30 includes a sounding element 31 and a first elastic element 33, the sounding element 31 is disposed on the base 10 in a liftable manner, and the first elastic element 33 is connected to the base 10 and the sounding element 31 and can drive the sounding element 31 to ascend; the pressing assembly 20 includes a pressing body 21 and a pressing abutting portion 22, the pressing body 21 is disposed on the base 10 in a liftable manner, the pressing abutting portion 22 is connected to the pressing body 21, the pressing abutting portion 22 is movably abutted to the pressing body 21, and when the pressing body 21 is driven to be separated from the sounding element 31, the first elastic element 33 drives the sounding element 31 to collide with the pressing body 21; the cushion member 40 is provided on one of the base 10 and the pressing body 21, and when the pressing body 21 is lifted relative to the base 10, the cushion member 40 can be brought into contact with the other of the base 10 and the pressing body 21.

Specifically, when the pressing member 20 is not pressed, the pressing abutting portion 22 abuts against the sounding abutting portion 313, so that the sounding body 311 is fixed to the base 10 at the lower limit of the clamping between the pressing abutting portion 22 and the first elastic member 33, and at this time, the first elastic member 33 is in a compressed state. When the pressing assembly 20 presses, the pressing body 21 descends, so that the sounding abutting portion 313 and the pressing abutting portion 22 are separated from each other to make the sounding body 311 not limited and fixed to the base 10, and at this time, the first elastic element 33 is elastically driven to restore to the original state to drive the sounding body 311 and the pressing body 21 to collide with each other. It can be understood that, because the collision between the sounding part 31 and the pressing component 20 in the present application occurs in the process that the pressing component 20 descends and the sounding body 311 ascends, the two move towards each other at this time, and a large collision impact force can be generated, so that the strength of the prompt sound sent by the sounding component 30 can be improved, and the user can be prompted effectively. The first elastic member 33 may be a spring, or of course, a plastic material with certain elasticity, which is not limited in this application, and it is sufficient that the first elastic member 33 has certain elasticity to drive the sounding member 31 to ascend. In another embodiment, the sounding element 30 may be a torsion spring connected to the pressing body 21, and the base 10 is provided with a surface for guiding the torsion spring to rotate. When the torsion spring descends with the pressing of the main body 21, the torsion spring is deformed by the guide action of the surface of the base 10 for guiding the torsion spring to rotate, and collides with a part of the base 10 when returning to its original shape, thereby generating a warning sound.

Referring to fig. 2 and 4, in an embodiment of the present invention, the base 10 includes a base body 11 and a mounting platform, the mounting platform is connected to the base body 11, and the mounting platform is disposed in a ring shape; the sounding piece 31 comprises a sounding body 311 and a sounding abutting part 313, the sounding body 311 is embedded in the mounting table in a lifting manner and can rotate relative to the mounting table, the sounding abutting part 313 is connected to the lateral peripheral surface of the sounding body 311 and abuts against the pressing abutting part 22, and the pressing body 21 is arranged in the seat body 11 in a lifting manner; when the pressing body 21 is lowered, the pressing contact portion 22 drives the sounding body 311 to rotate relative to the mounting table, so that the pressing contact portion 22 and the sounding contact portion 313 are separated; the first elastic member 33 is connected to the base 10 and the sounding body 311, and can drive the sounding body 311 to collide with the pressing body 21. The cushion member 40 is provided on one of the holder body 11 and the pressing body 21, and when the pressing body 21 is lifted relative to the holder body 11, the cushion member 40 can be brought into contact with the other of the holder body 11 and the pressing body 21.

Specifically, the pressing abutting portion 22 drives the sounding body 311 to rotate relative to the mounting table, so that the sounding abutting portion 313 and the pressing abutting portion 22 are displaced from each other, and the pressing abutting portion 22 is not abutted against the sounding abutting portion 313, that is, the two portions are separated from each other, thereby unlocking the state in which the sounding body 311 is fixed to the base 10 in a limited manner. It can be understood that, locate base 10 with the sound production body 311 is rotatable, can be so that the projection area of sound production body 311 is located the rotation orbit of sound production body 311 all the time on base 10, so can avoid other structures on this sound production body 311 and base 10 to bump and influence follow-up sound production body 311 and press the effect that body 21 collided mutually in order to send the suggestion sound. Meanwhile, the sound-emitting body 311 can be installed compactly due to the arrangement, so that the occupation of space is reduced. Of course, the present invention is not limited to this, and in other embodiments, the sounding body 311 may be only disposed on the base 10 in a liftable manner, and when the pressing abutting portion 22 abuts against the groove structure on the side peripheral surface of the sounding abutting portion 313, the sounding body 311 may be fixed to the base 10 in a limited manner; when the pressing member 20 is lowered to be separated from the groove structure on the side circumferential surface of the sounding abutting portion 313, the sounding body 311 may not be fixed to the base 10 in a limited manner, that is, the sounding body 311 and the pressing abutting portion 22 may be separated from each other. Further, the sounding element 31 may be provided with at least two sounding abutting portions 313, the at least two sounding abutting portions 313 are all connected to the side peripheral surface of the sounding body 311 and are evenly distributed around the center of the sounding body 311 at intervals, at this time, the pressing abutting portions 22 may be correspondingly provided with at least two pressing abutting portions 22, and one pressing abutting portion 22 abuts against one sounding abutting portion 313. By increasing the number of the sounding abutment portions 313 and the pressing abutment portions 22 in this way, the stability of the position-restricting fixation of the sounding material 31 can be improved, and the sounding body 311 is prevented from being lifted by the first elastic member 33 when the pressing body 21 is not pressed. In addition, the seat body 11 may be provided with a mounting hole 11 a.

In an embodiment of the present invention, the sounding abutting portion 313 has an upper end and a lower end which are oppositely disposed, the upper end of the sounding abutting portion 313 is formed with a sounding abutting surface 313a, the sounding abutting surface 313a abuts against the pressing abutting portion 22, the lower end of the sounding abutting portion 313 is formed with a sounding rotating surface 313b, and a projection line of the sounding rotating surface 313b on the side circumferential surface of the sounding body 311 is spirally disposed; the inner wall of the mounting table is convexly provided with a first rotary guide block 131, the first rotary guide block 131 is positioned below the sounding abutting part 313, one end of the first rotary guide block 131 facing the sounding rotary surface 313b is provided with a first rotary guide surface 131a, and the first rotary guide surface 131a is matched with the sounding rotary surface 313 b.

Specifically, when the pressing abutment portion 22 drives the sounding abutment portion 313 to descend by a certain distance, the sounding abutment portion 313 can cooperate with the first rotation guide surface 131a of the first rotation guide block 131 through the sounding rotation surface 313b to guide, so that the sounding body 311 can rotate relative to the mounting table. Further, the sounding contact portion 313 rotates and is displaced from the pressing contact portion 22, and at this time, the sounding body 311 is not fixed at a limited position and is driven by the first elastic member 33 to ascend, so that the sounding body 311 and the pressing body 21 collide with each other.
