Description

TRANSMISSION DEVICE FOR PUSH-BUTTON SWITCH, PUSH-BUTTON

SWITCH AND SOCKET

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to a push-button switch, and more particularly to an improvement of an operation-state indication of a push-button switch.

BACKGROUND

[0002] The push-button switch is widely used in homes, factories and other fields. As is well known in the art, unlike the rocker switch, the push-button switch includes a push button that protrudes from the panel, and the operation state of the push-button switch is switched by pressing the push button. For example, when the switch is initially in the on state, if the push button is pressed, the switch is switched to the off state. Then, the push button is released, the push button springs back and the switch remains in the off state. When the switch remains in the off state, if the push button is pressed, the switch is switched to the on state. Then, the push button is released, the push button springs back and the switch remains in the on state. Therefore, the push-button switch needs an indication means to indicate the operation state of the push-button switch. However, the driving of the indication means for the push-button switch in the prior art is complicated and has a large number of parts, so it is expected to further improve the driving.

[0025] Embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the same numerals may be used for similar parts or functional components in the drawings. The accompanying drawings are merely intended to illustrate the embodiments of the present disclosure. Those skilled in the art can obtain alternative embodiments from the following descriptions without departing from the spirit and the protection scope of the present disclosure.

[0026] A transmission device for a push-button switch according to embodiments of the present disclosure will be described below with reference to Figs. 1-8. It should be understood that a structure of the push-button switch in the drawings is merely exemplary, and some features not related to an inventive concept of the present application are simplified or omitted. In addition, in the illustrated features, some invisible lines or features not relevant to the present application are illustrated with dashed lines.

[0027] It should be understood that although the present application illustrates the inventive concept of the present application with a push-button switch combined in a socket, the specific implementation forms of the push-button switch are various. For example, the push-button switch can be used as a standalone switch part and also can be integrated in another part to operate as a module therein. These variations are all covered by the protection scope of the present application. In addition, direction terms such as upper, lower, left and right described below are merely for convenience of description, but not for limitation. In actual implementations, the direction can be changed according to actual applications.

[0028] As shown in Fig. 1, the push-button switch according to embodiments of the present disclosure includes a cover 1 and an installation panel 2. The installation panel 2 can be fixed to a support surface (such as a wall or the like) with a screw. The cover 1 can be mounted to the installation panel 2 in a way of covering the installation panel 2, thereby form a decorative surface of the push-button switch.

[0029] As shown in Fig. 1, the push-button switch according to embodiments of the present disclosure includes a push button 10, a transmission means, and a rocker 40.

[0030] The transmission device includes a transmission means 20. The transmission means 20 includes a driving part 26 and is configured, in responding to a pushing action of the push-button switch, to drive, by the driving part 26, the rocker 40 to pivot. The transmission means 20 further includes an indication part 22 to provide an indication function of indicating operation states of the push-button switch.

[0031] The transmission device further includes an elastic means 30 for driving the indication part to move so as to provide the indication function. The elastic means 30 is disposed between the transmission means and the rocker 40 of the push-button switch and extends in a plane perpendicular to a pushing direction. The elastic means 30 is configured to move in responding to a pivoting of the rocker 40 of the push-button switch, so as to drive the transmission means to move between a first predetermined position and a second predetermined position. The first predetermined position corresponds to an on state of the push-button switch and the second predetermined position corresponds to an off state of the push-button switch.

[0032] The rocker 40 is pivotably mounted to a housing of the push-button switch and is configured to pivot in responding to a downward movement of the transmission means 20, such that a moving contact 50 of the push-button switch is driven to pivot by the rocker 40, so as to contact or to be separated from a fixed contact 60 of the push-button switch.

[0033] With the transmission device according to embodiments of the present disclosure, when the push button 10 of the push-button switch is pushed, the elastic means 30 moves in the plane perpendicular to the pushing direction in response to the pivoting of the rocker 40 and is elastically deformed through the movement thereof; when the push button 10 of the push-button switch is released, the transmission means 20 is driven to move by means of a restoring force of the deformed elastic means 30.

[0034] Compared with the prior art, the transmission device according to the embodiments of the present disclosure realizes two functions of transmission and indication, has few parts and a low cost, and is convenient to assemble and convenient to produce.

[0035] For example, in an embodiment, a top surface of the transmission means 20 is provided with the indication part 22. The indication part 22, for example, may be an area marked with different colors. The push button 10 is provided with an opening window 12 in a predetermined position. When the indication part 22 is slid to the predetermined position, the indication part 22 is exposed out of the opening window 12, so that the operation state of the push-button switch is observable to the user. In another embodiment, the indication part may be configured as an independent means attached to the transmission means.

[0036] According to an embodiment of the present disclosure, the elastic means 30 is pivotably mounted to the push-button switch. In the illustrated embodiment, the cover 1 has a shaft 11 protruding from the cover body, and the elastic means 30 is provided with an opening 31 (refer to Figs. 3 and 4), such that the elastic means 30 can be pivotably mounted to the cover 1 in a manner of a shaft-hole fit. Although in the illustrated embodiment, the elastic means 30 is mounted to the cover 1, in other embodiments, the elastic means may also be mounted to a suitable portion of the installation panel.

[0037] According to an embodiment of the present disclosure, the elastic means 30 is configured in a following manner: in the case that the transmission means 20 is in the first predetermined position, when the push button of the push-button switch is pushed to actuate the push-button switch, the elastic means 30 pivots by a certain stroke in a first direction in the plane perpendicular to the pushing direction and presses a pushing part of the transmission means 20 so as to be deformed, and also, the transmission means 20 is maintained in the first predetermined position and not moved; when the push button of the push-button switch is released, the transmission means 20 is driven to move to the second predetermined position by a restoring force of the elastic means 30, so as to change a state indication of the push-button switch; in the case that the transmission means 20 is in the second predetermined position, when the push button of the push-button switch is pushed to actuate the push-button switch, the elastic means 30 pivots by a certain stroke in a second direction opposite to the first direction and presses the pushing part of the transmission means 20 so as to be deformed, and also, the transmission means 20 is maintained in the second predetermined position and not moved; when the push button of the push-button switch is released, the transmission means 20 is driven to move to the first predetermined position by the restoring force of the elastic means 30, so as to change the state indication of the push-button switch.

[0038] In the illustrated embodiment, the elastic means 30 is configured in a following manner: when the rocker of the push-button switch pivots, a shaft 42 of the rocker pushes an edge of the opening 31, and thus the elastic means 30 pivots.

[0039] According to an embodiment of the present disclosure, the elastic means 30 includes two opened arms, namely first and second arms 34, the transmission means includes first and second pushing parts 24 arranged correspondingly to the first and second arms. In the first predetermined position, the first elastic arm abuts against the first pushing part, and in the second predetermined position, the second elastic arm abuts against the second pushing part. The pushing part contributes to the deformation of the elastic arm.

[0040] The structure and operation principle of the transmission device for the push-button switch according to the embodiments of the present disclosure will be described below in combination with the operation process of the push-button switch. As is well known in the art, the push-button switch has only two operation states, i.e. an on state and an off state. When the push button is pushed and released, the operation state of the push button is switched. Each time the push button is pushed and released, the operation state of the push button is switched once. Therefore, the push-button switch needs to be provided with an indication device for indicating the operation state of the push-button switch. The design difficulty of the indication device lies in how to use the on-off switching movement of the push-button switch to realize the drive of the indication device.

[0041] As shown in Fig. 2, in an initial state, the moving contact 50 and the fixed contact 60 are engaged with each other, and the switch is in the on state. In this state, the rocker 40 is in the initial tilted position, and one driving part 26 (a left driving part in the drawing) of the transmission means 20 abuts against one slave part 46 (a left driving part in the drawing) of the rocker 40. However, as the transmission means and the rocker are in an equilibrium state, there is no relative movement therebetween.

[0042] In this state, the transmission means 20 is stationary, and the indication part 22 is exposed from out of the opening window 12, so that the operation state of the push-button switch is observable to the user through the opening window 12.

[0043] As shown in Fig. 3, in this state, the elastic means 30 is in the first predetermined position where the first arm 34 (an upper arm in the drawing) of the elastic means 30 abuts against the pushing part 24 of the transmission means. For clarity of illustration, the pushing part 24 is not shown in the drawing. This feature can best be seen from Fig 6. As shown in Fig. 6, in this position, the first arm 34 (the upper arm in the drawing) of the elastic means 30 abuts against the pushing part 24 of the transmission means. Preferably, there is a certain elastic force between the first arm 34 and the pushing part 24 to prevent the transmission means from moving due to an external interference.

[0044] When the user desires to turn the switch off, the user needs to press the push button 10 and then release the push button 10. The operation of pressing and releasing realizes the operation of turning off the push-button switch. Moreover, the push button 10 maintains in the state that the moving contact 50 and the fixed contact 60 are separated, when the user releases the push button 10. Descriptions will be made in the following based on Fig. 2 and Fig. 3 in combination with Fig. 4 and Fig. 5.

[0045] As shown in Fig. 4 and Fig. 5, when the user pushes the push button 10, the push button 10 moves downwards to push the transmission means 20 to move downwards; as the transmission means 20 moves downwards, the left driving part 26 of the transmission means 20 presses down the left slave part 46 of the rocker 40; since the rocker 40 is pivotably connected to a main body of the push-button switch, the rocker 40 rotates counterclockwise (the direction observed in the drawing) around the rotating shaft 48 along with the left driving part 26 of the transmission means 20 pressing down the left slave part 46 of the rocker 40; along with the rotation of the rocker 40, the rotation movement drives the moving contact 50 to rotate clockwise so as to be separated from the fixed contact 60, thereby turning off the switch. It should be noted that the push button 10 is not released yet.

[0046] In this process, the elastic means 30 is pivotably connected with the push-button switch, and the elastic means is configured to move in response to the rotation of the rocker 40. In the illustrated embodiment, since the shaft 42 of the rocker extends through the opening 31 of the elastic means 30, and the rocker 40 rotates counterclockwise around the rotating shaft 48, so the shaft 42 presses an inner edge of the opening 31 to drive the elastic means 30 to pivot in a horizontal plane, so as to move from a position shown in Fig. 3 to a position shown in Fig. 5. As shown in Fig. 5, in combination with Fig. 6, in this position, the second arm of the elastic means 30 presses the second pushing part 24 of the transmission means 20 and is elastically deformed.

[0047] At the same time, since the user’s hand is still pressed on the push button 10, the transmission means 20 remains in the original position under the pressure of the push button 10. In other words, although the moving contact 50 and the fixed contact 60 have been separated at this time, the indication part 22 still remains in the exposed position and is not moved. It should be noted that, at this moment, the elastic means 30 is subject to the acting force of the shaft 42, and the elastic means 30 presses the second pushing part 24 and is elastically deformed.

[0048] Then, when the user releases the push button 10, the pressure acted on the transmission means 20 is removed. Therefore, the transmission means 20 slides to the right under the restoring force of the elastic means 30 (refer to Fig. 4), so that the indication part 22 of the transmission means 20 moves to the right side of the push button 10 and is hidden by the push button 10, that is, the user cannot see the indication part 22 of the transmission means 20 through the opening window 12.

[0049] At the same time, the right driving part 26 of the transmission means 20 moves to a position corresponding to the right slave part 46 of the rocker 40. The moving contact 50 and the fixed contact 60 are kept in the separated state, and the push-button switch is kept in the off state.

[0050] Then, when the user desires to turn on the push-button switch, the user can press the push button 10 to perform a process similar to the entire process from Fig. 2 to Fig. 5 described above, so as to achieve a position from off to on; in this process, the indication part 22 moves from the right hidden position to the left exposed position, so as to indicate the on state of the switch. For the sake of brevity, its detailed description is omitted.

[0051] The structure details of the push-button switch and the transmission device of the present application will be further described below with reference to Fig. 6 to Fig. 7.

[0052] In the illustrated embodiment, the push button 10 includes a cavity defined by its top and side walls, and the transmission means 20 is slidably mounted to the push button 10 of the push-button switch. Sliding is used to drive the transmission means, so the moving process of the transmission device is simple and it is convenient to control the movement of the transmission means.

[0053] According to an embodiment of the present disclosure, as shown in Fig. 6, the push button 10 is provided with a sliding rail 14, and the transmission means 20 is slidably mounted to the sliding rail 14. As shown in Fig. 6, two sides of the transmission means 20 are provided with a sliding part 24, and the sliding part 24 can be mounted to the sliding rail 14. By the way of sliding engagement, a motion resistance of the transmission means 20 is small and the driving thereof is simple.

[0054] Fig. 7 shows schematic structure details of the rocker 40. As shown in Fig. 7, the rocker 40 includes the rotating shaft 48, and the rocker 40 can be pivotably mounted to the push-button switch through the rotating shaft 48 (e.g., mounted to the installation panel). Fig. 6 also shows the shaft 42 for driving the elastic means 30 to move. Although the illustrated shaft 42 is cylindrical, a shape of the shaft 42 is not limited in any way.

[0055] Fig. 8 shows a schematic view of an elastic means 30’ according to another embodiment of the present disclosure. The elastic means 30’ and 30 in the illustrated embodiment employ a structure of two elastic arms, so the movement stroke of the elastic means can be reduced and the size of the switch can be decreased. However, in other embodiments, the elastic means 30’ and 30 may have one or more elastic arms, and the concept of the present invention may be implemented as well.

[0056] According to an embodiment of the present disclosure, as shown in Fig. 9, the push-button switch is divided into two portions. One portion of the push-button switch can be configured in the form of the installation panel fixed in the support surface such as the wall or the like, and the installation panel can be fixed to the support surface (such as the wall or the like) with a screw. The other portion of the push-button switch can be configured in the form of the cover matched with the installation panel, and the cover can cover the installation panel and be fitted with the installation panel. With this solution, the push-button switch is convenient to assemble.

[0057] In an embodiment, the rocker 40, the moving contact 50 and the fixed contact 60 form the installation panel portion adapted to be mounted to the support surface. The push button 10, the transmission means 20 and the elastic means 30 form the cover portion separated from the installation panel portion. In an embodiment, as shown in Fig. 9, the rocker 40 may be divided into two portions. For example, a separate portion of the rocker 40 provided with the shaft 42 may be configured as a part of the cover, and the rest portion of the rocker 40 may be configured as a part of the installation panel. These two can be mounted together by means of surface fit. In order to ensure that the separate portion provided with the shaft 42 can be rotated together with the rest portion of the rocker, the separate portion can be provided with a shaft 44, and the separate portion is rotatably mounted to the main body of the cover through the shaft 44. It should be understood that a person skilled in the art would conceive other ways of dividing the rocker 40, under the teachings of the present disclosure.

[0058] According to another aspect of the present disclosure, there is provided a socket, including the above push-button switch for controlling power-on and power-off of the socket. Thus, the push-button switch can control power-on and power-off of a jack in the socket. In other embodiments, the push-button switch can be integrated into other electrical devices. These devices all have the advantages of the transmission device according to embodiments of the present application.

[0059] With the teachings presented in the foregoing descriptions and the associated drawings, many modifications and other embodiments of the present disclosure herein will recognized by those skilled in the art to which the present disclosure pertains. Therefore, it should be understood that the embodiments of the present disclosure are not limited to the disclosed specific embodiments, and that modifications and other embodiments are intended to be included within the scope of the present disclosure.
