In the embodiment of the present invention, a multifunctional key structure 100 is provided at first, which is applied to an electronic product, and is used for implementing corresponding control, such as turning on and off, volume adjustment, etc., on the electronic product through the multifunctional key structure 100. Among these, electronic products include, but are not limited to: smart phones, tablet computers, smart watches and other smart devices having a plurality of keys.

As shown in fig. 1 and 2, the multi-function key structure 100 includes a housing 10 and a switch assembly 20. The housing 10 is generally an outer case of an electronic product. For example, the switch assembly 20 is generally disposed on a side surface of the housing 10 and electrically connected to components in the electronic product, so as to implement corresponding control. The switch assembly 20 includes a first switch 21, and a second switch 22 and a third switch 23 respectively disposed at two sides of the first switch 21 at an interval. It can be understood that the first switch 21, the second switch 22 and the third switch 23 can be set to be corresponding control adjusting switches according to the requirement of the electronic product, and the invention is not limited herein. Taking a mobile phone as an example, the first switch 21 may correspond to a power key of an electronic product, and the second switch 22 and the third switch 23 may correspond to an increase switch and a decrease switch of an output volume of the electronic product, respectively.

Specifically, the casing 10 is provided with a key hole 11 spaced from the switch assembly 20, that is, the pressing portion of the switch assembly 20 is disposed toward the key hole 11, so that the user can press the switch assembly 20 through the key hole 11. So that a space for elastic deformation when pressed is left between the key hole 11 and the switch assembly 20. A push-pull bar 30 is arranged between the key hole 11 and the switch assembly 20, and a user can press or push the push-pull bar 30 to move between the key hole 11 and the switch assembly 20 to realize the respective control of the switch assembly 20.

A spring plate 40 is disposed between the push-pull strip 30 and the switch assembly 20, in this embodiment, the length of the spring plate 40 is longer than that of the push-pull strip 30, and when the push-pull strip 30 is pushed in the direction of the two ends, the vertical projection of the two ends of the push-pull strip 30 relative to the spring plate 40 is still within the range of the spring plate 40. The elastic sheet 40 is made of flexible steel, and when the elastic sheet is pressed, the elastic sheet locally can generate elastic deformation, and when the pressure disappears, the elastic sheet 40 can restore to the original shape. It can be understood that the push-pull strip 30 and the elastic sheet 40 are both fixed in a preset cavity of the housing 10, so as to prevent the push-pull strip 30 and the elastic sheet 40 from falling from the key hole 11 and separating from the control range of each switch in the switch assembly 20.

Both ends of the push-pull strip 30 near the spring plate 40 are provided with pressing protrusions 31 corresponding to the second switch 22 and the third switch 23. In the present embodiment, the pressing protrusion 31 has a triangular or semicircular shape, so that when the push-pull strip 30 is pushed to move to both sides, the pressing protrusion 31 located in front of the moving direction can press the elastic sheet 40 to press the second switch 22 or the third switch 23. At this time, the pressing bump 31 located behind the moving direction and the elastic sheet 40 are in an unpressed state.

When the middle part of the push-pull strip 30 is pressed, the elastic sheet 40 is forced to press the first switch 21, and at this time, the elastic deformation of the middle part of the push-pull strip 30 is the largest, so that the elastic sheet 40 also generates corresponding elastic deformation, and the first switch 21 is pressed. At this time, since both ends of the push-pull bar 30 have a certain distance from the pressed portion, the generated elastic deformation is almost negligible, and the second switch 22 and the third switch 23 are not pressed by the pressing protrusion 31. It should be noted that, in order to reduce the difficulty in pressing the middle of the push-pull strip 30, a protrusion structure 32 is disposed at a side of the middle of the push-pull strip 30 close to the elastic sheet 40, so as to reduce the requirement on the elastic deformation range of the middle of the push-pull strip 30 when controlling the first switch 21.

Specifically, as shown in fig. 3-5, the elastic sheet 40 is recessed along a direction close to the switch assembly 20 to form two recessed portions 41 for accommodating the pressing protrusion 31, and the two recessed portions 41 are respectively located at a position between the first switch 21 and the second switch 22 and a position between the first switch 21 and the third switch 23. When the pressing protrusion 31 moves in the corresponding recess 41, the end of the pressing protrusion 31 closest to the spring 40 does not press the spring part in the recess 41. When the pressing bump 31 passes over the edge of the corresponding recess 41, the pressing bump 31 presses the elastic sheet 40 at the opposite position of the second switch 22 or the third switch 23, and at this time, the other pressing bump 31 is still in the corresponding recess 41, thereby realizing the independent control of the second switch 22 and the third switch 23. When the middle portion of the push-pull strip 30 presses the first switch 21, both the pressing protrusions 31 are located in the corresponding recesses 41.

Further, in an embodiment, a limit bump 33 is disposed in the middle of the push-pull strip 30 on a side away from the elastic sheet 40, and the limit bump 33 passes through the key hole 11 and is limited in the key hole 11 so as to limit a range in which the push-pull strip 30 can move towards both sides. Specifically, the key hole 11 and the limiting bump 33 are both long strips, and the length of the key hole 11 is greater than that of the limiting bump 33, so that the limiting bump 33 can move within a certain range in the key hole 11. The stop tab 33 also facilitates the user pushing and pressing the push-pull strip 30. Furthermore, the side of the limit protrusion 33 away from the push-pull bar 30 is provided with a plurality of convex patterns 331, and the convex patterns 331 increase the friction coefficient of the push-pull limit protrusion 33 on one hand, and also have an identification function, for example, being configured in a "+" - "shape, corresponding to the volume adjustment functions of the second switch 22 and the third switch 23.

Furthermore, both ends of the push-pull strip 30 are provided with return springs 34; the return spring 34 is used to move the limit projection 33 to the middle of the key hole 11. That is, the elastic forces generated by the return springs 34 at both ends of the push-pull bar 30 are identical and opposite, so that the push-pull bar 30 is maintained at the initial position in the middle of the key hole 11 when it is not in use. Specifically, the two ends of the push-pull strip 30 are provided with fixing posts 35, and each return spring 34 is sleeved on the corresponding fixing post 35. The casing 10 has fixing grooves (not shown) spaced apart from both ends of the push-pull bar 30, and one end of the return spring 34, which is far away from the push-pull bar 30, is received in the fixing grooves, so that the return spring 34 can be always in a contracted state.

To sum up, the multifunctional key structure 100 provided by the present invention forces the elastic sheet 40 to press the first switch 21 by pressing the middle portion of the push-pull strip 30, thereby realizing the control of the first switch 21; when the push bar 30 is pushed to move towards both ends, the pressing bumps 31 at both ends of the push bar 30 press the both ends of the elastic sheet 40, so as to control the second switch 22 and the third switch 23. Therefore, through the combination of the push-pull strip 30 and the elastic sheet 40, when the touch of the physical key is ensured, three-key integration is realized, and not only can the redundant operation during the adjustment of the switch be reduced, but also the design space requirement of the switch is reduced.

A second aspect of the present invention provides an electronic product (not shown in the drawings), which includes the multifunctional key structure 100 according to any one of the above embodiments.

The invention is not limited solely to that described in the specification and the embodiments, and additional advantages and modifications will readily occur to those skilled in the art, and it is not intended to be limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
