Referring to fig. 1, fig. 3 and fig. 4, in an embodiment of the present invention, the key includes a base 10, an upper cover 30, a pressing member 50 and a sound generating assembly 70; wherein, the upper cover 30 covers the base 10 and forms an accommodating cavity with the base 10; the pressing piece 50 is arranged in the accommodating cavity in a lifting way, and part of the pressing piece penetrates out of the upper cover 30 to the outside; the sounding assembly 70 includes a first elastic member 71 and a sounding member 73, the first elastic member 71 is disposed in the accommodating cavity and connected to the base 10 and/or the upper cover 30, the sounding member 73 is disposed in the accommodating cavity and connected to the first elastic member 71, the sounding member 73 is movably abutted against the pressing member 50, and when the pressing member 50 is driven to descend and separated from the sounding member 73, the sounding member 73 is driven to ascend by the first elastic member 71 and collide with the upper cover 30.

In an embodiment of the present invention, the base 10 is mainly used to form a containing cavity in cooperation with the upper cover 30 to contain the pressing element 50 and the sounding component 70, so that each component of the key forms a whole and is convenient to be installed on the keyboard body of the keyboard. The connection mode of the base 10 and the keyboard body can be screw connection or buckle connection, etc. so as to simplify the connection structure of the keys and the keyboard body. Similarly, the connection between the upper cover 30 and the base 10 may be detachable, for example: screw connection or buckle connection etc. to when the spare part in the holding chamber takes place to damage, can dismantle base 10 and upper cover 30 and improve the convenience of maintenance change. And the projections of the base 10 and the upper cover 30 on the horizontal plane can be square, rectangular or circular, etc., so that the base 10 and the upper cover 30 have regular shapes and are convenient to manufacture. In order to reduce the overall quality of the keys and make the keyboard portable, the base 10 and the cover 30 may be made of plastic, for example: for example: ABS, POM, PS, PMMA, PC, PET, etc. Of course, in order to increase the strength of the keys and prolong the service life of the keyboard, the base 10 and the upper cover 30 may be made of metal materials, such as: stainless steel materials, aluminum alloy materials, copper alloy materials, iron alloy materials and the like. The pressing member 50 may be mainly used to implement a key function of the key by a pressing action to input text, symbols or numerical information. The working principle is as follows: when the pressing member 50 is driven to descend, the optical path between the optical transmitter and the optical receiver on the keyboard body of the keyboard can be blocked or conducted, and at this time, the control circuit board in the keyboard body of the keyboard can detect the blocking or conduction of the optical signal, so that the key function is realized.

Of course, a related light emitter, a light emitter, or a contact switch may be disposed in an accommodating cavity formed by enclosing the base 10 and the upper cover 30 of the key. Since the principle of the key function realized by pressing the key is the prior art, it is not described in detail herein. In order to facilitate the user to apply a force to the pressing member 50, a key cap is disposed at an end of the pressing member 50, which extends out of the upper cover 30 to the outside, so as to increase a contact area with the user and improve the convenience of pressing. The sounding member 73 of the sounding assembly 70 is mainly used to generate a sound when colliding with the upper cover 30 during ascending, and the first elastic member 71 is mainly used to provide power to drive the pressing member 50 to ascend. The general process of the sounding may be: when the pressing member 50 is not pressed and driven, the sounding member 73 is located at an initial position (at this time, the pressing member 50 may abut against the upper end of the sounding member 73, or may have a certain gap from the upper end of the sounding member 73); when the pressing member 50 is driven to descend, the sounding member 73 can be driven to be separated from the pressing member 50, and the first elastic member 71 is compressed, so that the sounding member 73 is driven by the first elastic member 71 to ascend and collide with the upper cover 30. The first elastic member 71 may be a spring or a plastic member with certain elasticity.

The technical scheme of the utility model the button is when being pressed, and external drive pressing piece 50 can drive sound production piece 73 of sound production subassembly 70 when descending and remove to make sound production piece 73 break away from mutually with pressing piece 50 and not by spacing fixed. At this time, the first elastic member 71 of the sounding component 70 can drive the sounding component 73 to rise to collide with the upper cover 30, so that the key can give out a prompt sound when being pressed. 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, sound generating component 70 in this scheme is located and is enclosed the holding intracavity that closes the formation by base 10 and upper cover 30, and the chamber wall through this holding chamber has certain effect of protection to sound generating component 70, reduces its possibility that receives the damage to can prolong the life of this button. In addition, the receiving cavity is formed by the base 10 and the upper cover 30 in a matching manner, so that the two can be manufactured independently and assembled into a whole after being manufactured and formed respectively. The complexity of the forming of the accommodating cavity can be reduced, and therefore the convenience of forming and manufacturing the key is improved.

Referring to fig. 3 and 6, in an embodiment of the present invention, the first elastic member 71 is rotatably connected to the base 10 or horizontally slidably connected to the base 10, and when the pressing member 50 is driven to descend, the pressing member 50 drives the first elastic member 71 to rotate or horizontally slide relative to the base 10, so that the pressing member 50 and the sounding member 73 are separated.

It can be understood that, when the first elastic member 71 is rotatably connected to the base 10, so that the pressing member 50 drives the first elastic member 71 to rotate relative to the base 10 when descending, the sounding member 73 connected to the first elastic member 71 can rotate while descending to be misaligned with the pressing member 50, thereby achieving the disengagement of the pressing member 50 and the sounding member 73. The first elastic member 71 is rotatably disposed on the base 10, so that the projection areas of the first elastic member 71 and the sounding member 73 on the base 10 are always located in respective rotation tracks, thereby reducing the occupation of space. When the first elastic member 71 is horizontally movably connected to the base 10, so that the pressing member 50 drives the first elastic member 71 to slide relative to the base 10 when descending, the sounding member 73 connected to the first elastic member 71 can slide while descending to be misaligned with the pressing member 50, thereby realizing the disengagement of the pressing member 50 and the sounding member 73. The first elastic member 71 is slidably provided on the base 10, so that the movement path of the first elastic member 71 and the sounding member 73 on the horizontal plane is linear and has a short movement path, and the sounding member 73 and the pressing frame can be quickly separated from each other. Wherein, the horizontal sliding of the first elastic member 71 means: the sliding direction of the first elastic member 71 is perpendicular to the lifting direction of the pressing member 50.

In an embodiment of the present invention, the base 10 is provided with the mounting circular truncated cone 11 protruding along the lifting direction of the pressing member 50 in the accommodating cavity, and the first elastic member 71 is sleeved on the outer side of the mounting circular truncated cone 11 and can rotate or horizontally slide relative to the mounting circular truncated cone 11.

It can be understood that the arrangement of the mounting circular truncated cone 11 simplifies the mounting structure of the first elastic element 71, that is, the first elastic element 71 is directly sleeved on the outer side of the mounting circular truncated cone 11, so that the assembly efficiency of the key can be improved. When the first elastic member 71 is rotatably connected to the base 10, the inner diameter of the first elastic member 71 may be the same as the outer diameter of the mounting boss 11; when the first elastic member 71 is horizontally slidably coupled to the base 10, the inner diameter of the first elastic member 71 may be larger than the outer diameter of the mounting boss 11. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the first elastic member 71 may be provided with a rotating shaft, the base 10 is provided with a rotating hole, and the rotating connection of the first elastic member 71 is realized through the cooperation of the rotating shaft and the rotating hole; or the first elastic part 71 is provided with a sliding block, the base 10 is provided with a sliding groove, and the sliding connection of the first elastic part 71 is realized through the matching of the sliding block and the sliding groove. In addition, the first elastic member 71 may be rotatably connected to the upper cover 30, or may be horizontally slidably connected to the upper cover 30.

Referring to fig. 3, 5 and 6, in an embodiment of the present invention, the base 10 is formed with a base guide surface 13, the base guide surface 13 is disposed obliquely downward and is located below the sounding element 73, when the pressing element 50 is driven to descend, the sounding element 73 is driven to descend, and the base guide surface 13 guides the sounding element 73 to move so as to drive the first elastic element 71 to rotate or horizontally slide relative to the mounting circular truncated cone 11.

It will be understood that the base guide surface 13 is configured to drive the sounding member 73 to move when the pressing member 50 is driven to descend, and indirectly drive the first elastic member 71 to rotate or horizontally slide relative to the mounting boss 11 through the sounding member 73. In this case, the driving structure of the pressing member 50 for the first elastic member 71 and the sounding member 73 can be simplified, and the base guide surface 13 provided on the base 10 can drive the first elastic member 71 when the sounding member 73 is driven to move, thereby reducing the manufacturing cost of the key by simplifying the structure. Of course, the present application is not limited thereto, and in other embodiments, a link may be rotatably connected between the first elastic member 71 and the pressing member 50, and when the pressing member 50 is driven to descend, the link drives the first elastic member 71 to rotate or horizontally slide relative to the base 10. In addition, in order to further facilitate the rapid detachment of the pressing member 50 and the sounding member 73, the pressing member 50 may be provided with a pressing guide surface 51 at a position corresponding to the sounding member 73, the pressing guide surface 51 is positioned above the sounding member 73 and is disposed obliquely upward and movably abutted against the sounding member 73, and at this time, the sounding member 73 may be driven to move by being guided by the cooperation of the pressing guide surface 51 and the base guide surface 13.

Referring to fig. 3, 4 and 5, in an embodiment of the present invention, the base 10 further forms a base avoiding groove 15, the base avoiding groove 15 is disposed adjacent to the base guiding surface 13, and the base guiding surface 13 can guide the sounding element 73 to move into the base avoiding groove 15.

It can be understood that the arrangement of the base avoiding groove 15 gives an avoiding space, reduces the possibility that the sounding element 73 interferes with a part of the structure on the base 10 during the moving process, and ensures that the sounding element 73 is accurately separated from the pressing element 50. Also, in order to reduce the possibility that the sounding member 73 interferes with a part of the structure of the pressing member 50 during the movement, the pressing member 50 may be provided with a pressing avoiding groove 53, and the pressing avoiding groove 53 and the base avoiding groove 15 are oppositely disposed to avoid the ascending process of the sounding member 73.

Referring to fig. 4, in an embodiment of the present invention, the upper cover 30 is formed with an upper cover guide surface 31, the inclined directions of the upper cover guide surface 31 and the base guide surface 13 are the same, and the upper cover guide surface and the base avoidance groove 15 are disposed just opposite to each other, and when the sounding member 73 is driven to ascend by the first elastic member 71, the sounding member 73 collides with the inclined surface of the base 10.

It can be understood that the arrangement of the upper cover guiding surface 31 can realize the collision with the sounding piece 73 during the lifting process to generate sound; and also has a guiding function for the sounding member 73 so that the sounding member 73 is restored to the original position. Specifically, when the pusher 50 is driven to descend and is disengaged from the sounding member 73, the sounding member 73 is driven to ascend by the first elasticity and collides with the upper lid guide surface 31 to generate a sound. After the pressing member 50 is lifted up, when the side wall surface of the pressing member 50 does not block the sounding member 73, the sounding member 73 may be driven by the first elastic member 71 to continuously lift up and move along the upper cap guide surface 31 to complete the reset. Thus, the sound emitting member 73 is automatically reset, thereby further improving the convenience of use of the key. Of course, in other embodiments, the sounding element 73 may be connected to a poke rod, and the poke rod penetrates from the upper cover 30 to the outside, so that the resetting of the sounding element 73 can be manually driven by a human to move so as to drive the sounding element 73 to reset.

Referring to fig. 2 and 3, in an embodiment of the present invention, the pressing member 50 is provided with a guide post 55 protruding in the accommodating cavity, and the guide post 55 extends along the lifting direction of the pressing member 50; the base 10 is provided with a guide hole 17 on the inner side of the mounting round table 11, and the guide post 55 is inserted into the guide hole 17 in a liftable manner.

It can be understood that the cooperation of the guide post 55 and the guide hole 17 has a guiding function for pressing the pressing member 50, and the pressing member 50 can be reduced from being displaced during the pressing process, so that the pressing member 50 can accurately drive the sounding member 73 to abut against the sounding member. Meanwhile, the arrangement can also make the installation of the devices more compact, thereby reducing the occupation of space.

Referring to fig. 3, in an embodiment of the present invention, the key further includes a second elastic member 90, the second elastic member 90 is sleeved outside the guiding column 55, and two ends of the second elastic member 90 respectively abut against a wall surface of the base 10 where the circular truncated cone 11 is installed and a wall surface of the guiding column 55 where the pressing member 50 is installed.

It can be understood that the pressing member 50 can be driven by the second elastic member 90 to ascend and return after being pressed to descend, that is, when the pressing member 50 is driven to descend, the second elastic member 90 can be compressed to generate a deformation elastic force. When the external force acting on the pressing member 50 is canceled, the second elastic member 90 drives the pressing member 50 to ascend under the condition that the deformation elastic force is restored, so that the pressing member 50 is reset. In this way, the automatic reset of the pressing piece 50 is realized, thereby further improving the convenience of use of the key. Of course, in other embodiments, the pushing element 50 may be connected to a shifting rod, and the shifting rod passes through the upper cover 30 to the outside, so that the pushing element 50 can be reset by manually driving the shifting rod to move to drive the pushing element 50 to reset. The second elastic member 90 is sleeved outside the guide post 55, and the guide post 55 can also guide the second elastic member 90, so that the second elastic member can only apply an acting force to the pressing member 50 along the extending direction of the guide post 55, thereby further improving the stability of the pressing member 50 in the lifting process. Of course, the second elastic member 90 may be provided with a position in which the receiving cavity is not provided with the guide post 55, and both ends thereof may be respectively abutted against the pressing member 50 and the base 10. In addition, the second elastic member 90 may be a spring or a plastic member with certain elasticity.

It can be understood that the collision column 731 and the first elastic member 71 are of an integral structure, which can enhance the connection strength of the two, and improve the connection stability of the two; meanwhile, the two parts can be manufactured through integral forming, so that the processing technology is simplified and the production efficiency is improved. Here, the number of the collision columns 731 may be one, but may also be two, and the two collision columns 731 are evenly spaced around the center of the first elastic member 71. In this case, two base guide surfaces 13 may be correspondingly disposed on the base 10, and the two base guide surfaces 13 have rotational symmetry with respect to the center of the base 10 when the first elastic member 71 is rotatably connected to the base 10, and have axial symmetry with respect to the center of the base 10 when the first elastic member 71 is slidably connected to the base 10. Two base avoiding grooves 15, two upper cover guiding surfaces 31 and two upper cover 30 avoiding grooves are correspondingly arranged.

In this case, the number of the collision columns 731 may be one, but may be two, and the two collision columns 731 are uniformly spaced around the center of the body portion 733. Similarly, two base guide surfaces 13 may be correspondingly disposed on the base 10, and the two base guide surfaces 13 have rotational symmetry about the center of the base 10 when the first elastic member 71 is rotatably connected to the base 10, and have axial symmetry about the center of the base 10 when the first elastic member 71 is slidably connected to the base 10.
