The subject matter herein generally relates to control devices, and more particularly to a control device having a button structure.
A control device, such as a doorbell, generally includes a signal transmitting mechanism, and the signal transmitting mechanism is triggered by a button structure to generate a doorbell sound when the button structure is pressed. Existing button structures are generally injection molded or welded. A button structure formed by injection molding may be difficult to form during molding, may be difficult to maintain, and have high cost. The welded button is prone to deviate in position, have high cost, and requires screws for disassembly and assembly.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a column, but can have one or more deviations from a true column. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The housing 10 includes a front wall 12 and four sidewalls 14 that are coupled to the front wall 12. The four sidewalls 14 are respectively coupled to four sides of the front wall 12. The front wall 12 and the four sidewalls 14 cooperatively define a receiving cavity 16. The receiving cavity 16 is configured to receive the button 30 and the signal transmitting mechanism.
In one embodiment, one of the sidewalls 14 defines a through hole 141 communicating with the receiving cavity 16. The button 30 partially extends through the through hole 141. It can be understood that in other embodiments, the through hole 141 may be defined in the front wall 12.

In one embodiment, the front wall 12 includes a latching block 121. The latching block 121 is adjacent to the sidewall 14 in which the through hole 141 is mounted and cooperatively defines a latching slot 140 with the sidewall 14. One end of the resilient arm 33 extends away from the pressing portion 31 into the latching slot 140. In one embodiment, a distance between the latching block 121 and the corresponding sidewall 14 is 1.35 mm, but is not limited thereto. It can be understood that in other embodiments, the latching slot 140 may be defined in the front wall 12.
An inner wall of the through hole 141 limits movement of the button 30 along a first direction and a second direction, and the sidewall 14 and the latching block 121 limit movement of the button 30 along a third direction. The first direction, the second direction, and the third direction are substantially perpendicular to each other.
In one embodiment, the resilient arm 33 includes a connecting portion 332, a curved portion 334, and a latching portion 336 coupled together in sequence. The connecting portion 332 is coupled to the pressing portion 31. The latching portion 336 is latched in the latching slot 140. When the pressing portion 31 is pressed, the curved portion 334 is resiliently deformed, and when the pressing portion 31 is released, the pressing portion 31 is resiliently restored.
In one embodiment, the housing 10 includes a positioning block 18. The positioning block 18 includes a curved surface 181 corresponding in shape to the curved portion 334. The positioning block 18 is used to position the curved portion 114. In one embodiment, the positioning block 18 is located between the front wall 12 and the sidewall 14 where the resilient arm is located, but is not limited thereto. In other embodiments, a location of the positioning block 18 is set according to a shape of the curved portion 334.
It can be understood that in other embodiments, the positioning block 18 can be omitted. It can be understood that in other embodiments, the curved portion 334 may be omitted as long as the resilient arm 33 can be elastically deformed.
In one embodiment, a reinforcing block 3321 (shown in
In one embodiment, one side of the second column 314 facing away from the first column 312 defines a clearance groove 3141. A bottom wall of the clearance groove 3141 includes a pressing rod 3143. The pressing rod 3143 is configured to press and trigger the signal transmitting mechanism. The clearance groove 3141 is for receiving components of the signal transmitting mechanism.
When the button 30 is assembled, the latching portion 336 is first inserted into the latching slot 140, and the pressing portion 31 is pressed to elastically deform the curved portion 334 to fit the pressing portion 31 into the through hole 141.
It can be understood that the button 30 can also be applied to other control devices that require a button trigger mechanism besides a doorbell.
The button 30 of the control device 100 has a simple structure and low manufacturing cost, is easy to assemble, and does not require a fixing member such as a screw to be assembled.
In one embodiment, the through hole 141 is a circular hole. The pressing portion 31 includes a first column 312 and a second column 314 coupled to the first column 312. A diameter of the first column 312 is less than a diameter of the second column 314. The first column 312 is movably mounted through the through hole 141, and the second column 314 is configured to resist against the sidewall 14. The resilient arm 33 is coupled to a peripheral wall of the second column 314. It can be understood that in other embodiments, the second column 314 can be omitted, such that the resilient arm 33 resists against the sidewall 14 to retain the first column 312 in the through hole 141.
When the pressing portion 31 is pressed, the pressing portion 31 slides within the through hole 141 to trigger the signal transmitting mechanism within the housing to emit a signal and causes the resilient arm 33 to deform. When the pressing portion 31 is released, the resilient arm 33 latched in the latching slot 140 is resiliently restored to cause the pressing portion 31 to return to an initial position.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
