[0039] Please see Figure 1 and Figure 2 , Figure 1 This is a first exploded perspective view of an electronic device provided in an embodiment of the present application. Figure 2A second exploded perspective view of an electronic device provided in an embodiment of the present application. The present application provides an electronic device 10. The electronic device 10 includes a housing 1 and a circuit board 2 disposed inside the housing 1. The electronic device 10 includes, but is not limited to, computer equipment, communication equipment, consumer electronic products, etc. Accordingly, the circuit board 2 includes, but is not limited to, hardware such as motherboards and power boards of computers and electronic products, communication modules in communication equipment, antennas and other components, sensors in consumer electronic products, etc., which are not described in detail here.

[0040] In this embodiment, the circuit board 2 is provided with a pot switch 21. The electronic device 10 also includes a combination switch key 3 arranged outside the circuit board 2. In this embodiment, the circuit board 2 is a flexible circuit board. The pot switch 21 is used to control the activation and / or deactivation of the electronic device 10. For example, the pot switch 21 can be used to control the activation and / or deactivation of the power-on function or the power-off function of the electronic device 10, or to control the activation and deactivation of certain functions of the electronic device 10. Taking a liquid crystal handwriting board as an example, a pot switch 21 is provided in the liquid crystal handwriting board, and the pot switch 21 is used to control the activation and deactivation of the clearing function of the liquid crystal handwriting board. The pot switch 21 is controllably pressed or cannot be pressed through the combination switch key 3, thereby controllably realizing that certain functions of the electronic device 10 can be activated and / or deactivated, or cannot be activated and / or deactivated. Specifically, the pot switch 21 includes a pot (not shown) located on the circuit board and a contact corresponding to the pot (not shown). When the pot switch 21 is pressed through the combination switch key 3, the center point of the pot is sunken to trigger the corresponding contact point so that the contact point is turned on, thereby triggering the circuit 22 corresponding to the contact point on the circuit board 2 to control the activation and / or shutdown of certain functions corresponding to the circuit 22 in the electronic device 10. When the pot switch 21 cannot be pressed through the combination switch key 3, the center point of the pot cannot be sunken to trigger the corresponding contact point so that the contact point cannot be turned on, thereby failing to trigger the circuit 22 corresponding to the contact point on the circuit board 2 to control the activation and / or shutdown of certain functions corresponding to the circuit 22 in the electronic device 10.

[0041] It can be understood that by controlling the pressing or failing to press the pot switch 21 through the combination switch key 3 provided on the outside of the circuit board 2, it is possible to realize that there is no need to provide an additional switch control on the circuit board 2 to control the pot switch 21 to execute the control of enabling and / or disabling the electronic device 10, or controlling the enabling and disabling of certain functions of the electronic device 10, thereby simplifying the structure of the circuit board 2, reducing the production cost of the circuit board 2, and reducing the space occupied by the circuit board 2 in the electronic device 10, thereby improving the space utilization rate of the electronic device 10. The following will explain how to controllably press or fail to press the pot switch 21 through the combination switch key 3 by explaining the specific features of each component of the combination switch key 3.

[0042] Please see Figure 3 , Figure 6 and Figure 7 , Figure 3 A schematic diagram of the structure of a sliding key provided in an embodiment of the present application, Figure 6 This is a first three-dimensional exploded view of the combination switch key provided in an embodiment of the present application. Figure 7 This is a second stereoscopic exploded view of the combination switch key provided in an embodiment of the present application.

[0043] like Figure 1 and Figure 6 As shown, the housing 1 includes a first housing 11 and a second housing 12. The second housing 12 and the first housing 11 are arranged opposite to each other. The second housing 12 is provided with a receiving groove 121, so that the first housing 11 is arranged on the second housing 12 through the receiving groove 121. The combination switch key 3 includes a sliding key 32 and a pressing key 31. Among them, the sliding key 32 and the pressing key 31 are respectively assembled on the housing 1, and the sliding key 32 and the pressing key 31 are respectively located on the opposite sides of the circuit board 2, that is, the pressing key 31, the circuit board 2 and the sliding key 32 are arranged in sequence. Among them, the pressing key 31 is assembled on the first housing 11, and the pressing key 31 is arranged toward the pot switch 21. The pressing key 31 is used for the user to perform a pressing operation, so that the pressing key 31 can be operably pressed to move toward the circuit board 2 and press the pot switch 21 to trigger the pot switch 21. The first housing 11 can be a thin film with a small thickness, such as a plastic sheet. Accordingly, the push button 31 can be a key spring provided on a plastic sheet, so that the user can perform a pressing operation. The size and shape of the plastic sheet are adapted to the second housing 12 to improve the stability of the first housing 11 when the user performs a pressing operation through the push button 31. Among them, the outer surface of the second housing 12 is provided with a sliding groove 123. The sliding key 32 is assembled to the second housing 12 through the sliding groove 123, so that the sliding key 32 can slide in the sliding groove 123 relative to the housing 1.

[0044] In some feasible embodiments, when the first shell 11 is disposed on the second shell 12 through the accommodating groove 121, a plurality of through holes 122 can be penetrated at corresponding positions of the first shell 11 and the second shell 12, so that the first shell 11 can be fixed to the second shell 12 through a plurality of fixing parts (not shown) at the plurality of through holes 122, thereby further improving the stability when the user performs a pressing operation.

[0045] like Figure 2 , Figure 3 and Figure 7As shown, the sliding key 32 includes an operating portion 321 disposed on the outside of the housing 1, and a locking portion 322 disposed on the inside of the housing 1. The operating portion 321 is connected to the locking portion 322. The operating portion 321 is disposed on the outside of the second housing 12, and the locking portion 322 is disposed on the inside of the second housing 12. The locking portion 322 slides between the locked position and the unlocked position as the operating portion 321 slides, so as to switch the pressing key 31 between the locked state and the unlocked state, thereby controllably connecting or disconnecting the circuit 22 provided on the circuit board 2, or failing to connect or disconnect the circuit 22 provided on the circuit board 2. The following will specifically describe how to switch the pressing key 31 between the locked state and the unlocked state.

[0046] Please see Figure 4 and Figure 5 , Figure 4 A cross-sectional view of a locking portion provided in an embodiment of the present application when the locking portion is in a locking position, Figure 5 A partial cross-sectional view of the locking portion provided in an embodiment of the present application when in an unlocked position.

[0047] like Figure 4 and Figure 5 As shown, the locked position and the unlocked position are the two ends of the sliding groove 123. An opening 124 is provided at a position of the second shell 12 of the shell 1 corresponding to the sliding groove 123, so that the sliding key 32 can slide in the sliding groove 123 through the opening 124 and switch between the locked position and the unlocked position. When the locking portion 322 is in the locked position, the push key 31 is locked by the locking portion 322 and cannot be pressed to press the pot switch 21 and trigger the pot switch 21. When the locking portion 322 is in the unlocked position, the push key 31 is unlocked and can be operably pressed to press the pot switch 21 and trigger the pot switch 21. Specifically, the locking portion 322 includes a protrusion protruding toward the push key 31. When the locking portion 322 is in the locked position, the protrusion is opposite to the push key 31 and presses against the push key 31, thereby preventing the push key 31 from being pressed, and further preventing the push key 31 from being pressed to the point where it presses the pot switch 21 and triggers the pot switch 21. When the locking portion 322 is in the unlocked position, the protrusion offsets the push key 31 to a position outside the path of movement of the push key 31, thereby unlocking the push key 31, so that the push key 31 can be pressed to the point where it presses the pot switch 21 and triggers the pot switch 21. The present application realizes controllably connecting or disconnecting the circuit 22 provided on the circuit board 2, or failing to connect or disconnect the circuit 22 provided on the circuit board 2, by switching the locked state and the unlocked state of the push key 31, thereby simplifying the structure of the circuit board 2.

[0048] It can be understood that the push button 31 is defined as a locked state or an unlocked state by whether it can be pressed to press the pot switch 21. As long as it can be controllably achieved that the push button 31 cannot be pressed to press the pot switch 21 and trigger the pot switch 21, the circuit 22 on the circuit board 2 can be controllably triggered or not triggered. The present application can also achieve the switching of the lock state or the unlock state of the push button 31 by changing the positional relationship between the push button 31 and the pot switch 21 when the sliding button 32 slides until the push button 31 cannot be pressed to press the pot switch 21 and trigger the pot switch 21. By way of example, the circuit board 2 can be deformed by changing the position of the locking portion 322, thereby changing the relative positions of the pot switch 21 and the push button 31, so that the push button 31 can be pressed or cannot be pressed until the pot switch 21 is pressed to trigger the switching of the state of the pot switch 21, that is, the push button 31 is switched between a locked state and an unlocked state.

[0049] In this embodiment, the sliding key 32 further includes a base 323. The operating portion 321 and the protrusion are respectively arranged on the first and second opposite surfaces of the base 323, that is, the operating portion 321 and the locking portion 322 are arranged on opposite sides relative to the base 323. Preferably, the first and second surfaces face the pressing key 31 and the sliding key 32, respectively. In order to enable the sliding key 32 to stably slide in the sliding groove 123, the size of the base 323 is larger than the size of the opening 124.

[0050] In this embodiment, a limiting portion 324 is further provided on the second surface. The limiting portion 324 is used to limit the position of the circuit board 2, so as to ensure that the sliding key 32 and the pressing key 31 are always located on opposite sides of the circuit board 2 when the pressing key 31 switches between the locked state and the unlocked state. The protrusion and the limiting portion 324 are arranged at intervals along the sliding direction of the sliding key 32, and the sliding direction of the sliding key 32 corresponds to the path of movement of the pressing key 31. The limiting portion 324 includes two limiting plates 3241. The two limiting plates 3241 are arranged opposite to each other and are located on both sides of the circuit board 2. Preferably, the height of the two limiting plates 3241 is the same as the height of the protrusion.

[0051] Please continue to see Figure 6 and Figure 7The present application also provides a combination switch key 3 of an electronic device 10. The electronic device 10 is provided with a housing 1. The combination switch key 3 in the present application includes a sliding key 32 and a pressing key 31. The sliding key 32 and the pressing key 31 are respectively assembled on the housing 1. The sliding key 32 can be operably slid relative to the housing 1 along a first direction, and the pressing key 31 can be operably pressed to move relative to the housing 1 along a second direction. The first direction is the sliding direction of the sliding key 32, and the second direction is the pressing direction of the pressing key 31. The sliding key 32 includes an operating portion 321 arranged on the outside of the housing 1, and a locking portion 322 arranged on the inside of the housing 1. The locking portion 322 slides between a locking position and an unlocking position as the operating portion 321 slides. Specifically, when the locking portion 322 is in the locking position, the pressing key 31 is locked by the locking portion 322 and cannot be pressed. When the locking portion 322 is in the unlocking position, the pressing key 31 is unlocked and can be operably pressed. In the present application, the combination switch key 3 can be directly mounted on the housing 1 of the electronic device 10, or the combination switch key 3 can be first mounted on a mounting shell (not shown) for accommodating the combination switch key 3, and then the mounting shell is mounted on the housing 1 of the electronic device 10 at a corresponding position where the circuit board 2 is located. The components of the combination switch key 3 have been described in detail at least in the above-mentioned electronic device 10, and will not be described in detail here.

[0052] In this embodiment, the locking portion 322 includes a protrusion protruding toward the push key 31. When the locking portion 322 is in the locking position, the protrusion is opposite to the push key 31, thereby preventing the push key 31 from being pressed. When the locking portion 322 is in the unlocking position, the protrusion deflects the push key 31, thereby unlocking the push key 31.

[0053] In the above embodiment, the pot switch provided on the circuit board is controllably pressed by means of a push key and a slide key provided outside the circuit board, thereby controllably triggering the circuit board or failing to trigger the circuit board, thereby simplifying the structure of the circuit board, reducing the production cost of the circuit board, and reducing the space occupied by the circuit board, thereby realizing the miniaturization of the circuit board of the electronic device.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0055] The above examples are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
