The arrangements of the holes 114g of the covering portion 110g and the holes 121g of the first contact portion 120g help decrease the stiffness of the flexible guiding component 100g, giving the activation assembly 10g a required tactile feedback. Note the arrangements, numbers, shape, and sizes of the holes 114g and the holes 121g relate to how the activation assembly 10g is going to respond to the push of the keycap 50. For example, the more quantity or larger sizes of the holes 114g and 121g are, the smaller force that is required to deform the activation assembly 10g is. In other words, the tactile feedback of the activation assembly 10g may be adjusted by modifying the arrangement of the holes 114g and 121g.
As shown in
The flexible guiding component 100g may be made of rubber, but the present disclosure is not limited thereto; in some other embodiment, the flexible guiding component 100g may be made of Mylar or polyethylene terephthalate (i.e., PET). Compared to the flexible guiding component made of Mylar and PET, the flexible guiding component made of rubber has a longer lifespan and produce less noise when using.
The elastic component 200g may be made of any suitable metal, such as metal. The elastic component 200g includes a coupling portion 210g and a plurality of support portions 220g. The coupling portion 210g of the elastic component 200g has a hole 211g. The coupling portion 210g is disposed on the first covering part 111g of the covering portion 110g and located in the cavity S. The coupling portion 210g may be simply placed on the covering portion 110g, or the coupling portion 210g may be fixed to the covering portion 110g via adhesive. The second contact portion 130g of the flexible guiding component 100g is disposed through the hole 211g. The support portions 220g extend outwards from the coupling portion 210g and are respectively located at the openings O, such that the support portions 220g are movable within the openings O without being interfered by the flexible guiding component 100g.
Each of the support portions 220g includes an inclined part 221g and a contact part 222g, where the contact part 222g is upturned and is connected to the coupling portion 210g via the inclined part 221g. There is a bent structure formed between the inclined part 221g and the contact part 222g of the support portion 220g, and the bent structure contacts the substrate 30. This helps prevent the elastic component 200g from damaging the substrate 30 when using.
Since the activation assembly 10g has a low height, the flexible guiding component 100g may further include a plurality of holding structures 115g and 116g. The holding structures 115g are connected to the second covering parts 112f and respectively and partially cover the openings O. The holding structures 116g are connected to the first covering part 111g and located in the cavity S, and respectively contact different sides of the elastic component 200g. As shown, the holding structures 115g are able to hold the support portions 220g of the elastic component 200g in the openings O so as to prevent the support portions 220g from coming out of the openings O. In addition, the support portions 220g are spaced apart from the second covering parts 112g so as to prevent the flexible guiding component 100g from interfering with the support portions 220g. Furthermore, the coupling portion 210f is firmly held in position by the holding structures 116g of the flexible guiding component 100g during operation.
Note that the manner used to dispose the coupling portion 210g on the covering portion 110g may be modified as require; in some other embodiment, the coupling portion may be fixed to the covering portion via melting process.
In this embodiment, the coupling portion 210g of the elastic component 200g has a circular shape, but the present disclosure is not limited thereto; in some other embodiments, the coupling portion of the elastic component may have a square shape. In addition, the elastic component 200g have four support portions 220g, but the present disclosure is not limited thereto; in some other embodiments, the elastic component may have any number of the support portions.
Referring to
In this embodiment, the keyboard 1000 may be applied to a notebook computer. The keyboard 1000 includes a casing 5 and a plurality of buttons 1. The buttons 1 are disposed on the casing 5. In this embodiment, the buttons 1 are the same as the button 1 shown in
Note that the activation assembly of each button 1 may be modified as required; in some other embodiment, each button of the keyboard may have the activation assembly shown in one of the previous embodiments.
According to the keyboard, the buttons, and activation assemblies disclosed in the above embodiments, the elastic component is held in position by the flexible guiding component; meanwhile, the flexible guiding component has the openings to avoid interference with the support portions of the elastic component during the deformation of the elastic component, such that the installation and the movement of the elastic component can be achieved by the flexible guiding component without any additional frame component. Therefore, the button can have a lower height for achieving a slim design and improving the tactile feedback.
Moreover, there is no gap between the coupling portion of the elastic component and the first covering part of the flexible guiding component, such that the elastic component can be moved along with the first covering part, thereby maintaining the tactile feedback of the button.
Furthermore, the flexible guiding component is made of soft rubber material, and the elastic component is made of metal material. Therefore, when the keycap 50 is released, the soft rubber material enables the flexible guiding component to recover to its original shape, and the elastic component made of metal material can help the flexible guiding component to recover to its original shape. Therefore, the button not only provides a strong tactile feedback, but also has a longer lifespan.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present disclosure. It is intended that the specification and examples be considered as exemplary embodiments only, with a scope of the disclosure being indicated by the following claims and their equivalents.
