Existing electronic devices typically use a key switch to turn on or off some functions of the electronic device, such as a power-on key, a power switch, and so on. In order to prevent misoperation of some key switches, electronic toggle switches are often added in electronic equipment to lock the key switches, that is, the circuit controlled by the key switches can be cut off by operating the toggle switches, so that the electronic equipment still cannot be operated even if the key switches are triggered. However, adding an electronic toggle switch increases the cost on the one hand, and on the other hand, because the electronic toggle switch has a service life and needs to be designed for a circuit, not only affects the overall service life of the electronic device, but also increases the complexity of the circuit design. In order to further reduce the cost and simplify the circuit design, the application adopts a mechanical mode to lock the key switch, can also prevent misoperation, and simultaneously reduces the cost. Specific embodiments of the present application will be described in detail below.

Referring to fig. 1, fig. 1 is a cross-sectional view of an electronic device provided by the present application. The present application provides an electronic device 1000. The electronic device 1000 includes a housing 200, a circuit board 300 disposed in the housing 200, and a combination switch 100 disposed on the housing 200.

The circuit board 300 is provided with a dome switch 301. In the present embodiment, the wiring board 301 is a flexible wiring board. The dome switch 301 is triggered by the combination switch key 100 for controlling the activation and deactivation of the functions of the electronic device 1000. For example, dome switch 301 may be used to control electronic device 1000 to power on and off, or to control the activation and deactivation of certain functions of electronic device 1000. Taking a liquid crystal handwriting board as an example, a dome switch 301 is arranged in the liquid crystal handwriting board, and the dome switch 301 is used for controlling the cleaning operation of the liquid crystal handwriting board. Specifically, the dome switch 301 includes a dome (not shown) on the wiring board 300 and contacts (not shown) corresponding to the dome. When pressed, the center point of the dome is depressed, which triggers the corresponding contact to turn on or off, thereby triggering the dome switch 301 to control the activation and deactivation of certain functions of the electronic device 1000. The dome switch 301 may be designed into a suitable shape according to actual needs, and the dome switch 301 in this embodiment may be designed as a rectangular dome switch, or the dome switch 301 may be designed as a circular dome switch (oval/elliptical), a cross dome switch, a triangular dome switch, or the like, and the shape of the dome switch 301 is not limited herein.

Referring to fig. 4, fig. 4 is an exploded perspective view of an electronic device according to the present application. In the present embodiment, the housing 200 includes a first panel 201 and a second panel 202. Wherein the first panel 201 and the second panel 202 are disposed opposite to each other. The outer side of the first panel 201 facing away from the second panel 202 is provided with a sliding groove 2011, and the bottom of the sliding groove 2011 is provided with an opening 2012.

The combination switch key 100 includes a toggle key 1 and a push key 2. The toggle key 1 and the push key 2 are respectively assembled to the housing 200. The toggle key 1 is operable to slide relative to the housing 200. The push key 2 is operatively pushed to move toward the circuit board 300 to trigger the dome switch 301. Specifically, the toggle key 1 and the push key 2 are respectively assembled on the first panel 201 and the second panel 202, and the toggle key 1 and the push key 2 are respectively located on two opposite sides of the flexible circuit board 300, and the push key 2 is disposed opposite to the dome switch 301. The push button 2 is movably mounted to the second panel 202, and the push button 2 is substantially circular, and moves toward the dome switch 301 to activate the dome switch 301 when pressure is applied to the push button 2 (the push button 2 is pushed). When the pressing force applied to the pressing key 2 is released (the pressing key 2 is not pressed), the pressing key 2 returns to the original position.

Referring to fig. 5 in combination, fig. 5 is a schematic structural diagram of a toggle key according to the present application. The toggle key 1 is mounted in the slide groove 2011 through the opening 2012 and is movable in the slide groove 2011. The toggle key 1 includes a base 13, an operation portion 11 provided outside the housing 200, and an actuation portion 12 provided inside the housing 200. The operating part 11 can be shifted to slide the actuating part 12 between the locking position and the unlocking position; when the actuating portion 12 is at the locking position, the actuating portion 12 acts on one of the pressing key 2 and the circuit board 300, so that the pressing key 2 cannot be pressed to trigger the dome switch 301 to bring the combination switch 100 into the locking state; when the operating portion 12 is in the unlock position, the push key 2 is unlocked and is operatively pushed to trigger the dome switch 301 to bring the combination switch 100 into the unlocked state. In the present embodiment, the actuation portion 12 acts on the circuit board 300, and the push key 2 is locked by changing the relative distance between the dome switch 301 and the push key 2 on the circuit board 300 so that the push key 2 cannot be pushed to contact with the dome switch 301.

The actuation portion 12 is provided with a trigger portion 121 and a lock portion 122 along the direction in which the operation portion 11 slides, and the actuation portion 12 and the operation portion 11 are located on first and second surfaces of the base 13 facing away from each other, respectively. Wherein a part of the first surface protrudes one protrusion in the direction of the flexible circuit board 300, so that the trigger part 121 formed locally and the first surface form the locking part 122 except for the part.

Further, the trigger portion 121 and the locking portion 122 are stepped, and a transition slope 123 is connected between the trigger portion 121 and the locking portion 122, and the height of the trigger portion 121 relative to the flexible circuit board 300 is higher than the height of the locking portion 122 relative to the flexible circuit board 300. When the operation portion 11 is slid to the unlock position, the trigger portion 121 approaches the dome switch 301 to move the dome switch 301 upward toward the push key 2; when the operating portion 11 is slid to the lock position, the trigger portion 121 moves away from the dome switch 301 to drop the dome switch 301 away from the push key 2. In the present embodiment, the relative distance between the dome switch 301 and the push key 2 is changed by changing the position of the dome switch 301 such that the dome switch 301 is supported by the trigger portion 121 or by the lock portion 122 and by using the difference in height between the trigger portion 121 and the lock portion 122; when the dome switch 301 is supported by the triggering portion 121, the dome switch 301 is allowed to contact with the pressing key 2, i.e., the triggering portion 121 is used for triggering the pressing key 2 to be effective; when the dome switch 301 is supported by the lock portion 122, the dome switch 301 cannot be brought into contact with the push key 2, i.e., the trigger portion 121 is used to lock the push key 2.

Referring to fig. 6 in combination, fig. 6 is a rear view of the electronic device provided by the present application. In this embodiment, the operation portion 11 is disposed in a waist-round shape, i.e., straight in the middle and arc-shaped on both sides, to fit the finger of the user. The end surface of the operating part 11 exposed out of the housing 200 is provided with a plurality of arc-shaped grooves 111, and the arc-shaped grooves 111 are arranged in parallel at a certain interval, so that the friction force contacted with the fingers of the user is increased, and the user can push the operating part 11 more easily.

In this embodiment, the operation portion 11 is exposed from the opening 2012, the shape of the opening 2012 attached to the operation portion 11 is also configured as a waist-round shape, the height of the operation portion 11 is greater than the height of the opening 2012, the length of the opening 2012 is greater than the length of the operation portion 11, and the operation portion 11 slides along the length direction of the opening 2012. It is understood that the length of the sliding groove 2011 is greater than the sum of the length of the operating portion 12 and the sliding length of the operating portion 11 from the unlock position to the lock position, and the length of the opening 2012 is greater than the sum of the length of the operating portion 11 and the sliding length of the operating portion 11 from the unlock position to the lock position.

Referring to fig. 2 and 3 in combination, fig. 2 is a partial cross-sectional view of an operating position in a locked position provided by the present application. Fig. 3 is a partial cross-sectional view of the operating portion provided by the present application in an unlocked position. The actuation portion 12 deforms the flexible circuit board 300 during sliding to correspondingly drive the dome switch 301 to move toward the push key 2 or away from the push key 2. Specifically, when the operation portion 11 is slid to the unlock position, the actuation portion 12 moves the dome switch 301 toward the push key 2 to be triggered by the push key 2, and the distance between the dome switch 301 and the push key 2 is smaller than or equal to the push distance of the push key 2, at which time the push key 2 is active; when the operation portion 11 is slid to the lock position, the actuation portion 12 moves the dome switch 301 away from the push key 2 so as not to be triggered by the push key 2, and the distance between the dome switch 301 and the push key 2 is greater than the push distance of the push key 2, at which time the push key 2 is not valid.

In this embodiment, assuming that the initial state of the electronic device 1000 is a power-off state, the toggle key 1 is located at the locking position, i.e. the pressing key 2 fails, and the electronic device 1000 cannot be turned on by operating the pressing key 2. To start the electronic device 1000, the toggle key 1 is slid to the unlock position to enable the key 2 to be pressed effectively, the key 2 is pressed at this time, the electronic device 1000 is started, the key 2 is pressed again, and the electronic device 1000 is shut down. In addition, when the electronic device 1000 is in the on state, in order to prevent the electronic device 1000 from being turned off by pressing the key 2 by a misoperation, the toggle key 1 can be slid to the locking position, and at this time, the pressing key 2 is disabled, so that the erroneous touch can be prevented.

The above-mentioned combination switch key 100 and the electronic device 1000 thereof, the circuit board 300 may be triggered or not triggered by the cooperation of the toggle key 1 and the pressing key 2, specifically, by sliding the toggle key 1, the pressing key 2 may not be pressed to the dome switch 301 provided on the trigger circuit board 300 to make the combination switch key 100 enter the locked state, or the pressing key 2 may be unlocked to be pressed to the dome switch 301 to make the combination switch key 100 enter the unlocked state. Namely, the pressing key 2 is locked or unlocked mechanically, so that the circuit design of the circuit board 300 and the circuit 302 is simplified, and meanwhile, the cost is reduced.

As can be appreciated, in this embodiment, by toggling the key 1 to make the flexible circuit board 300 drive the dome switch 301 to shift, the pressing key 2 is switched between being able and not able to trigger the dome switch 301. In some possible embodiments, in order to prevent the pressing key 2 from triggering the dome switch 301, the pressing key 2 may also be controlled to be unable to be pressed, for example, a structure that is capable of pushing the pressing key 2 may be provided on the toggle key 1, so that the pressing key 2 is capable of triggering or not triggering the dome switch 301 when the pressing key 2 is pressed or not pressed.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application. Thus, if and when such modifications and variations of the present application fall within the scope of the claims and the equivalents thereof, the present application is intended to encompass such modifications and variations.

The above list of preferred embodiments of the present application is, of course, not intended to limit the scope of the application, and equivalent variations according to the claims of the present application are therefore included in the scope of the present application.
