Description

PUSH-BUTTON SWITCH

TECHNICAL FIELD [0001] Various embodiments of the present invention relate to the field of switch, and in particular to a push-button switch.

PRIORITY [0002] This application claims priority from Chinese Patent Application No. CN201710698606.0 filed on 15 August 2017.

The entire content of this application is hereby incorporated by reference.

BACKGROUND [0003] The push-button switch is a typical type of switch that turns on and off one circuit alternately by repeatedly pressing a button, or alternately turns on two circuits.

[0004] After the button of the present push-button switch switches the on or off state of the push-button switch each time the button is pressed, the released button is reset to its initial position under the action of a resetting spring. After the button is reset to its initial position, a user cannot distinguish from the appearance or the rest position of the button whether the current operating state of the push-button switch is on or off, and other indicators associated with an actuating mechanism of the switch are often required to indicate the switch's states. However, the sizes of individual indicators are relatively small and may be located only at one edge of the push-button switch, which is disadvantageous for an observer to quickly identify them from different angles and distances. Moreover, the meaning of different identifiers on the indicators may not be intuitively and quickly understood by an observer who does not know the pushbutton switch. In addition, the provision of individual indicators leads to a complicated internal structure of the switch and possibly results in an increase in the size of the switch, because they

2018204743 29 Jun 2018 are required to be associated with the actuating mechanism of the switch.

SUMMARY [0005] According to an aspect of the present invention, there is provided a push-button switch, comprising a button movable in a button moving direction and having a first locking mechanism, and an actuating mechanism configured to swing in response to the push button being pressed from an initial position so as to switch between the on and off states of said push-button switch. A second locking mechanism is provided on said actuating mechanism, said second locking mechanism being configured to move between a first position and a second position with swinging of said actuating mechanism. When said button is released, said second locking mechanism engage with said first locking mechanism at said first position to lock said button at a stay position at a lower height than the initial position of said button, and said second locking mechanism disengages from said first locking mechanism at said second position to unlock said button so as to allow said button to reset to its initial position.

[0006] In some embodiments, the said second locking mechanism is configured to, when being at said first position, interfere with said first locking mechanism in said button moving direction to block said button from moving away from said actuating mechanism in said button moving direction, and no longer interfere with said first locking mechanism in said button moving direction to allow said button to move away from said actuating mechanism in said button moving direction when being at said second position.

[0007] In some embodiments, one of said first locking mechanism and said second locking mechanism is a locking hook bent in a plane perpendicular to a swing axis of said actuating mechanism, and the other of said first locking mechanism and said second locking mechanism is a lock catch adapted to engage with said locking hook.

[0008] In some embodiments, said lock catch is formed as a bent hook or a lock hole.

[0009] In some embodiments, both sides and/or both ends of the swing axis of said actuating mechanism are respectively provided with said locking hooks or said lock catches for providing

2018204743 29 Jun 2018 said second locking mechanism, and corresponding positions on said button are respectively provided with a corresponding number of lock catches or locking hooks for providing said first locking mechanism, so that the respective locking hooks are able to engage with the lock catches at corresponding positions, respectively.

[0010] In some embodiments, the push-button switch further comprises a button resetting spring; said button is configured to be driven by said button resetting spring to move toward the initial position of said button in said button moving direction with said first locking mechanism when being released.

[0011] In some embodiments, said actuating mechanism comprises a pivotally supported transition member and a pivotally supported pendulum rod, said second locking mechanism is provided on said transition member, and said transition member is configured to drive said pendulum rod to swing under the action of said button so as to switch between the on and off states of the push-button switch.

[0012] In some embodiments, said actuating mechanism comprises a pivotally supported pendulum rod, said second locking mechanism is provided on said pendulum rod, and said pendulum rod is configured to swing under the action of said button so as to switch between the on and off states of the push-button switch.

[0013] In some embodiments, said push-button switch further comprises a driving member, and said driving member is connected to said button, and is configured to move with said button under the action of said button so as to drive said actuating mechanism to swing.

[0014] In some embodiments, the said push-button switch is configured such that: when said push-button switch is in the on state, said second locking member is moved to its first position, so that said second locking member locks said button to said pause position when said button is released; and when said push-button switch is in the off state, said second locking member is moved to its second position, so that said second locking member unlocks said button so as to allow said button to reset to its initial position when said button is released.

DETAILED DESCRIPTION [0025] Various embodiments of the present invention will now be described in detail only by way of examples.

[0026] Referring to FIGS. 1 to 2, which show exploded views of a portion of a push-button switch according to some embodiments of the present invention, the push-button switch comprises a button enclosure 11; and a button 12 movably accommodated in a button moving direction in the button enclosure 11. The button moving direction mentioned herein refers to a direction in which the button 12 moves with respect to the button enclosure 11 or other stationary structures of the push-button switch after the button 12 is pressed by a user, and the button 12 moves while moving back to an initial position along an opposite movement path after the button 12 is released by the user.

[0027] The button 12 may be composed of a button body 121 and a button enclosure 122, and the button body 121 is adapted to form a space and a structure for accommodating other parts of the push-button switch, while the button enclosure 122 is adapted to be mounted to the top surface of the button body 210 for providing a smooth operating surface for the user. The button body 121 and the button enclosure 122 may also be integrally formed as one part as the button 12. Hereafter, only the term button is used to refer to the button body 121 and the button enclosure 122 as a whole.

[0028] An actuating member 14 is movably mounted in the button 12. The driving member 14 is connected to the button 12 so that it is moved along with the button 12 in the button moving direction when the button 12 is moved in the button moving direction, so as to drive the actuating mechanism action of the push-button switch to act. At the same time, the driving member 14 is also configured such that at least part of its structure (or the whole of the driving member 14) can be moved with respect to the button 12, so as to be able to drive the actuating mechanism to act on different sides of the actuating mechanism when the button 12 is operated by two consecutive presses, thereby switching between the on and off states of the push-button switch. This movement of the driving member 14 with respect to the button 12 may be a translation in a direction perpendicular to the button moving direction or may also be a swing about a pivot axis.

2018204743 29 Jun 2018

The driving member 14 is configured to be moved to its first or second stop in response to the button 12 being pressed. At the first stop, the driving member 14 drives an actuating mechanism (for example, including a transition member, a pendulum rod, and a conductive bridge) of the push-button switch to turn on or off a circuit to which the push-button switch is lock connected, and at the second stop, the driving member 14 drives the actuating mechanism of the push-button switch to reversely act and turn on or off the circuit to which the push-button switch is lock connected, thereby achieving the switching operation of the on and off states of the push-button switch.

[0029] In the embodiment shown in FIGS. 1-3, this movement of the driving member 14 with respect to the button 12 is a translation in a direction perpendicular to the button moving direction. In this embodiment, the driving member 14 has two fixed elastic legs 143 and two movable portions 141 movable with respect to the elastic legs 143. When the movable portion 141 moves linearly against the resistance of the elastic legs 143, the movable portion 141 can drive the actuating mechanism to act and switch between the on and off states of the push button switch. The elastic legs 143 of the driving member 14 are used as a resilience resetting element to bring the movable portions 141 of the driving member 14 back to their initially intermediate position by the elastic restoring force when the button is released.

[0030] It should be understood that other configurations and forms of driving member 14 may also be used to drive the actuating mechanism. For example, the driving member 14 may be movable in its entirety rather than only a portion, and a separate driving member resetting spring is additionally provided to making the driving member 14 be reset. The driving member 14 can also drive the actuating mechanism to act by moving pivotally about a pivot axis.

[0031] As shown in FIGS. 1 and 3, a lock catch 123 is provided on a side of the button 12 facing the actuating mechanism as a first locking mechanism. The lock catch 123 is formed as a bending hook that extends further downward from the bottom of the button 12 and then bends. The bending direction of the bending hook is substantially in the direction of the pivot axis of the actuating mechanism, which will be further described later.

2018204743 29 Jun 2018 [0032] An actuating mechanism is also provided below the driving member 14. The actuating mechanism includes, for example, a transition member 15 and a pendulum rod (not shown in Figs. 1 to 3). The transition member 15 and the pendulum rod are pivotally supported within the push-button switch, respectively, and their pivot axes (i.e., the swing axes) are parallel to each other. When the button 12 is pressed, the driving member 14 contacts and drives a side of the transition member 15 to swing the transition member 15, and the transition member 15 then drives the pendulum rod to swing toward the same side, thereby switching between the on and off states of the push button switch. It should be understood that the actuating mechanism may not be provided with the transition member 15, and the driving member 14 may be used to directly contact and drive the pendulum rod in the actuating mechanism to deflect the conductive bridge, so that switching the on and off states of the push-button switch is achieved.

[0033] In order to allow the button 12 to reset to its initial position when being released, a button resetting spring 16 is further provided between the button 12 and a stationary structure (e.g. button enclosure 11) of the push-button switch. One end of the button resetting spring 16 can directly abut the button 12 so that the button 12 is always provided with an elastic restoring force to reset the button 12 to the initial position.

[0034] As shown in FIGS. 1 to 2, a second locking mechanism is provided on a side of the transition member 15 facing the button 12. In the embodiment shown in FIGS. 1 to 2, the second locking mechanism is formed as a locking hook 151 that is bent in a plane perpendicular to the swing axis of the transition member 15 or the pendulum rod. The bending direction of the locking hook 151 is substantially perpendicular to the bending direction of the bending hook of the lock catch 123. Therefore, when the locking hook 151 swings about the swing axis along with the transition member 15, the bent portion of the locking hook 151 easily extends above the bent portion of the bending hook of the lock catch 123 and overlaps with it in the button moving direction. The bending direction and arrangement position of the locking hook 151 are appropriately set so that it is adapted to engage with the lock catch 123 on the button 12. Specifically, the bending direction and arrangement position of the locking hook 151 is set such that: when the transition member 15 is swung toward one direction, a bent end of the locking hook 151 on the transition member 15 can smoothly enter above the bent portion of a

2018204743 29 Jun 2018 corresponding lock catch 123 below the button 12 to reach its first position, so that the locking hook 151 overlaps with the lock catch 123 in the button moving direction to prevent the button 12 from moving away from the transition member 15 in the button moving direction; and when the transition member 15 is swung toward an opposite direction, the bent end of the locking hook 151 on the transition member 15 can be smoothly retreat from above the bent portion of the corresponding lock catch 123 below the button 12 to reach its second position, so that the locking hook 151 and the lock catch 123 no longer overlap in the button moving direction, so as to allow the button 12 to move away from the transition member 15 in the button moving direction.

[0035] When the locking hook 151 overlaps with the lock catch 123 in the button movement direction (i.e. the first position), even if the button 12 is released by the user and the button 12 tries to move upward away from the transition member 15 to its initial position under the action of the button resetting spring 16. However, because the locking hook 151 interferes with the lock catch 123 in the button movement direction, the button 12 is locked to a pause position at a lower height than the initial position of the button 12.When the locking hook 151 and the lock catch 123 no longer overlap in the button moving direction (i.e. the second position), the locking hook 151 no longer interferes with the lock catch 123 in the button movement direction and the button 12 is allowed to reset to its initial position under the action of the button resetting spring 16. Thus, at the first position, the button 12 is located at a certain pause position between its fully unpressed initial position and fully pressed operating position, in order to indicate a first state of the button to the user; and at the second position, the button 12 resets to its fully unpressed initial position, in order to indicate a second state of the button to the user.

[0036] In one embodiment, the engagement state of the locking hook 151 with the lock catch 123 is associated with the state that the actuating mechanism of the push-button switch is turning on the circuit connected to the push-button switch, so that the locking hook 151 is just moved to its first position when the push-button switch is in the on-state, and the locking hook 151 locks the button 12 to the pause position when the button 12 is released. This facilitates more intuitively indicating to the user that the push-button switch is currently in the on state, through the incompletely resetting appearance of the button 12. The disengagement state of the locking

2018204743 29 Jun 2018 hook 151 with the lock catch 123 is associated with the state of the circuit to which the actuating mechanism of the push-button switch is connected in the state that the actuating mechanism of the push-button switch is turning off the circuit connected to the push-button switch, so that the locking hook 151 is just moved to its second position when the push-button switch is in the offstate, and the locking hook 151 unlocks the button 12 to allow the button 12 reset to its initial position when the button 12 is released. This facilitates more intuitively indicating to the user that the push-button switch is currently in the off state, through the completely resetting appearance of the button 12.

[0037] In the embodiment shown in FIGS. 1 to 3, locking hooks 151 (a total of four locking hooks) are provided on both sides of the swing axis of the transition member 15 and on both ends of the swing axis, respectively, and a corresponding number of four lock catches 123 are respectively provided on corresponding positions on the button 12, to enable individual locking hooks 151 to engage with the lock catches 123 in the corresponding position. By providing locking hooks 151 and lock catches 123 at four different points in a major surface of the button 12, the button 12 can be simultaneously locked to a pause position with a lower height than the initial position of the button at multiple points. Thus, the button 12 can uniformly receive a force from the locking mechanism at the locked position, which ensures that the button 12 can still be at the locking position substantially perpendicular to the button moving direction without tilting, thereby ensuring the beautiful appearance of the button 12 at the locked position. In order to make each locking hook 151 reach to contact with the corresponding lock catch 123 at the same time after the button 12 is released, so as to apply resistance to the button 12 at the same time, the shape and size of each of the locking hooks 151 and the catches 123 should be set according to the tilting position of the transition member 15 or the pendulum rod when being at the first position (i.e. when the push-button switch is the on state), respectively.

[0038] However, it should be understood that the number of locking hooks 151 and locking hooks 123 is not limited to four. More or fewer than four locking hooks 151 and locking catches 123 may be provided, and locking hooks 151 and locking catches 123 may also be provided only at one side or one end of the swing axis of the transition member 15.

2018204743 29 Jun 2018 [0039] Although in the above embodiment, the first locking mechanism is provided as a locking hook and the second locking mechanism is set as a lock catch, it is also possible to provide the first locking mechanism as a lock catch and the second locking mechanism as a locking hook as long as they both can be engaged with and disengaged from each other by relative movement. In addition, the structure of the lock catch 123 may also be formed as an annular lock hole to engage with the locking hook 151. In the case where the lock catch 123 is formed as a bending hook, the extending direction of the bent portion of the bending hook may also be opposite to the direction shown in FIG. 1, that is, extends away from the center of the button 12.

[0040] In a case where the actuating mechanism does not include the transition member 15, the above-described second locking mechanism may be directly provided on the pendulum rod in the actuating mechanism. The arrangement and operation principle of the second locking mechanism on the pendulum rod is similar to the second locking mechanism described above with regard to the transition member 15, and will not be described in detail herein.

[0041] The operation of the push-button switch according to an embodiment of the present invention is described below with reference to FIGS. 4 to 9.

[0042] As shown in FIG. 4, when the push-button switch is in the first state, the button 12 is in the initial position where it is not pressed by the user. At this time, the transition member 15 is in a position tilted leftward, and the driving member 14 does not contact with the transition member 15 at this time. At the same time, the locking hook 151 on the transition member 15 is located at the lower left of the corresponding lock catch 123 on the button 12 without overlapping with it in the button moving direction so as not to engage with the corresponding lock catch 123.

[0043] As shown in FIG. 5, when the button 12 is pressed by the user, the driving member 14 moves downward with the button 12 and starts to contact with the right end of the transition member 15 below it.

[0044] As shown in FIG. 6, when the button 12 is further pressed, the right end of the driving

2018204743 29 Jun 2018 member 14 presses against the right end of the transition member 15, so that the transition member 15 swings clockwise and further drives the swing bar 17 to swing clockwise, thereby driving the deflection direction of the conductive bridge 18 to change. Consequently, the movable contact in the push-button switch is in contact with the stationary contact (not shown), and the circuit connected to the push-button switch is turned on. During the clockwise swing of the transition member 15, the locking hook 151 on the transition member 15 swing clockwise with the transition member 15 (not shown in FIG. 6), and the bent portion of the locking hook 151 starts to enter above the bent portion of the lock catch 123 (not shown in FIG. 6) on the lower side of the button 12 so as to overlap with the lock catch 123 in the button moving direction and then to reach its first position.

[0045] As shown in FIG. 7, when the button 12 is released by the user, the button 12 starts to reversely move in the button moving direction along with the lock catch 123 under the elastic restoring force of the button resetting spring 16 (not shown in FIG. 7) until the bent portion of the lock catch 123 comes into contact with the locking hook 151 on the transition member 15 and stops. At this time, the movement of the lock catch 123 and the push button 12 away from the transition member 15 in the button moving direction is prevented by the locking hook 151, due to the mutual interference between the lock catch 123 and the locking hook 151. Therefore, the button 12 is constrained to a stay position at a lower height than the initial position of the button 12 to indicate the on state of the push-button switch to the user.

[0046] As shown in FIG. 8, when the button 12 is pressed again, the driving member 14 moves downward with the button 12 again and starts to contact with the left end of the transition member 15 below it.

[0047] As shown in FIG. 9, when the button 12 is further pressed, the left end of the driving member 14 presses over the left end of the transition member 15 so as to drive the transition member 15 to swing counterclockwise and further drive the actuating mechanism to reversely act, so that the movable contact of the push-button switch disengages with the stationary contact, and thus the circuit connected to the push-button switch is turned off. During the clockwise swing of the transition member 15, the locking hook 151 on the transition member 15 swing

2018204743 29 Jun 2018 counterclockwise with the transition member 15, and the bent portion of the locking hook 151 starts to retreat from above the bent portion of the lock catch 123 (not shown in FIG. 9) on the button 12 so as to no longer overlap with the lock catch 123 in the button moving direction and then to reach its second position.

[0048] When the button 12 is released by the user again, the button 12 starts to reversely move in the button moving direction along with the lock catch 123 under the elastic restoring force of the button resetting spring 16. At this time, since the locking hook 151 and the lock catch 123 no longer overlap in the button moving direction, when the button 12 is reversely moved in the button moving direction along with the lock catch 123, the locking hook 151 no longer overlaps with the lock catch 123 in the button moving direction, and the button 12 and the lock catch 123 no longer interfere with each other in the button moving direction to prevent the movement of the push button 12 and the lock catch 123. Thus, the button 12 can be moved all the way to its completely unpressed initial position, to indicate the off state of the push-button switch to the user and to be ready for the next pressing operation. At this time, the push-button switch resets to the first state shown in FIG. 4.

[0049] It will be appreciated that, by associating different height positions of the button in the push-button switch with the on and off states of the push-button switch using a simple structure, it is possible to realize the indication of the on and off states of the push-button switch using the position state of the button, thereby achieving a more intuitive state indication of the push-button switch. Moreover, in some embodiments of the present invention, the locking mechanism for associating the different height positions of the buttons in the push-button switch with the on and off states of the push-button switch is directly located on the button and the actuating mechanism of the push-button switch without adding new parts, and thus the manufacture and assembly of the push-button switch is simplified. In addition, since there is no need to add other parts between the button and the actuating mechanism, and the locking mechanism does not occupy more space inside the push-button switch, the total height of the push-button switch can be set lower, thereby providing a push-button switch that is more compact and more widely applicable.

[0050] It should be understood that, for convenience of description, the description herein is

2018204743 29 Jun 2018 based on the placement orientation of the push-button switch shown in the accompanying drawings. The directions of “up, down, left, and right” in this article are all described based on this positioning. Obviously, the push-button switch can be arranged in various orientations as needed. However, the directional descriptions of “up, down, left, and right” between the features described in this document will change correspondingly with the change in the orientation of the button switch, but the relative positional relationship among the features will not change.

[0051] Throughout the specification and the claims that follow, unless the context requires otherwise, the words “comprise” and “include” and variations such as “comprising” and “including” will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers.

[0052] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that such prior art forms part of the common general knowledge.

[0053] The description of the present invention has been given for the purposes of illustration and description, but it is not intended to be exhaustive or be limited to the forms disclosed. Many modifications and variations will be conceived by those skilled in the art.

[0054] Therefore, the embodiments are selected and described in order to better explain the principles and practical applications of the present invention, and to enable other ordinary persons skilled in the art to understand that without departing from the spirit of the present invention, all modifications and alterations made will fall into the protection scope of the invention as defined by the appended claims.
