1. Technical Field
The present disclosure relates to a button assembly, especially to a push button assembly and an electronic device having such push button assembly.
2. Description of Related Art
Many push button assemblies include a switch and a button that, when pressed, actuates the switch. For an elongated button, if a user does not push the button very straight, there will be greater resistance to the pushing from the button being canted in its slot, which can be uncomfortable to a user and even cause injury.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring to
The rigid plate 10 has an elongated planar structure. The rigid plate 10 is arranged in a housing of the electronic device 200. In the exemplary embodiment, the rigid plate 10 is made of metal.
The circuit board 20 has a substantially elongated shape and is stacked on the rigid plate 10. The circuit board 20 includes a switch 21.
Referring to
The elastic element 30 includes a depressible portion 31 a fixing portion 34 fixed to the rigid plate 10. The depressible portion 31 is substantially an elongated plate and extends along the lengthwise direction of the button 40. The depressible portion 31 is substantially as long as the button 40. The depressible portion 31 is disposed between the circuit board 20 and the button 40. The depressible portion 31 defines a through hole 311 aligned with the switch 21. The protrusion 41 extends through the through hole 311 toward the switch 21. The button 40 can be fixed to the elastic element 30 by conventional connection techniques, such as screws. The elastic element 30 further includes a first elastic arm 32 and a second elastic arm 33 bending from opposite ends of the depressible portion 31 at a same side thereof. The ends of first elastic arm 32 and the second elastic arm 33 are both connected to the fixing portion 34.
When pressed, the button 40 moves and moves the elastic member 30. The protrusion 41 then actuates the switch 21. The first elastic arm 32 and the second elastic arm 33 are thus deformed when the button 40 moves the elastic member 30. Because the depressible portion 31 has the substantially length equal to that of the button 40, the button 40 can be pushed from different angles and will still easily cause the elastic element 30 to be deformed, thus the button 40 need not be operated so precisely and pushing it with standard force will not result in discomfort or injury to the user.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the present disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
