Another technical solution to solve the technical problem of the present invention is to provide an electronic device, which includes the above-mentioned button.

Compared with the prior art, the utility model provides a pair of button and electronic equipment has following advantage:

1. the utility model discloses first embodiment extrusion portion corresponds the setting with the sensing region, and extrusion portion is equipped with the cross-sectional area toward the part that the direction of keeping away from the sensing region diminishes gradually, and this part is first extrusion portion. When the extrusion parts are extruded, the cross sectional area of the same position of the first extrusion part is gradually increased under the extrusion force; and with the release of the extrusion force, the cross-sectional area of the same position of the first extrusion part is gradually restored to the initial state with the reduction of the extrusion force. Therefore, when the first squeezing part is squeezed, the cross sectional area of the first squeezing part is gradually increased along with the increase of the squeezing force, the area of the first squeezing part for transmitting force is also gradually increased, and the variation of the force sensed by the sensing area is also gradually increased along with the increase of the force transmission area of the first squeezing part; when the extrusion force of the first extrusion part is released, the cross-sectional area of the first extrusion part is gradually restored to the initial state along with the reduction of the extrusion force, the area of the first extrusion part for transmitting the force is also gradually reduced, and the variation of the force sensed by the sensing area is gradually increased along with the reduction of the force transmission area of the first extrusion part. It can be understood that, by adopting the arrangement mode, the variation of the force sensed by the sensing area can be accurately controlled according to the compression amount of the first pressing part, so that the sensing precision of the button can be improved; meanwhile, the first extrusion part can gradually increase the force transmission area while transmitting the extrusion force to the sensing area, so that the applied force can be well transmitted to the sensing area through the first extrusion part no matter whether the force application direction is over against the sensing area or not. The first squeezing part with the cross sectional area gradually changing towards the direction far away from the sensing area is more easily compressed when being squeezed, namely, the compression amount of the first squeezing part with the cross sectional area changing under the same squeezing force is larger, so that the pressing touch feeling of a user when the user presses the button can be improved while the size of a button triggering signal is not changed.

2.

In a similar way, when the housing moves towards the direction far away from the first extrusion part, the contact area between the first extrusion part and the housing can be gradually reduced, and then the pressure acting on the second extrusion part can be better released. Because the contact area between the first extrusion part and the shell is gradually increased or reduced, the variation of the force transmitted to the sensing area through the second extrusion part is gradually changed, and the arrangement mode can more accurately control the variation of the force sensed by the sensing area according to the compression amount of the first extrusion part, and has higher practicability. Meanwhile, the problem of poor consistency caused by installation errors can be well solved by controlling the extrusion force of the extrusion part on the sensing area in the initial state, and the reliability of the button is further improved. And because the cross-sectional area of the second extrusion part keeps unchanged towards the direction far away from the sensing area, the force acting on the second extrusion part can be transmitted to the sensing area more accurately. Meanwhile, the deformation amount of the second extrusion part with the unchanged cross section area is smaller when the second extrusion part is stressed, so that when the second extrusion part extrudes the sensing area, the second extrusion part does not excessively extrude the non-sensing area of the pressure sensor due to deformation, the interference of an electric signal output by the pressure sensor can be reduced, and the practicability is higher. Meanwhile, the second extrusion part which is relatively regular is more convenient for manufacturing the extrusion part.

3. The utility model discloses extrusion portion integrated into one piece in the first embodiment, second extrusion portion and first extrusion portion integrated into one piece adopt such mode of setting more to be convenient for the preparation and the installation of extrusion portion, also can strengthen the connection structure intensity between second extrusion portion and the first extrusion portion simultaneously, avoid droing between second extrusion portion and the first extrusion portion.

4. The utility model discloses first extrusion portion of first embodiment is the arc arch, and this arc arch has the arc curved surface, can understand, and each point of arc curved surface corresponds a position, and when any one local atress of arc curved surface, power all can be to dispersing evenly all around. Therefore, when the external part applies force to the pressing part, the applied force can be well transmitted to the sensing area through the first pressing part no matter whether the force application direction is opposite to the sensing area or not.

5. The utility model discloses the central point that first embodiment extrusion portion and sensing region put the corresponding setting. It can be understood that, because the extrusion portion directly corresponds the sensing region setting, consequently the extrusion portion can directly transmit pressure to the sensing region, and then reduces the pressure that the non-sensing region received, and the pressure that the non-sensing region received is less can reduce the interference to the signal of telecommunication of pressure sensor output, has further improved pressure sensor's sensing precision.

Referring to fig. 1 to 3, a first embodiment of the present invention provides a button 1, in which the button 1 includes a housing 11, an extruding portion 12, a pressure sensor 13 and a bearing portion 14, the housing 11 and the bearing portion 14 are disposed opposite to each other and form an installation space 15 for accommodating the extruding portion 12 and the pressure sensor 13. The pressure sensor 13 further includes a sensing region 131, the pressing portion 12 is provided corresponding to the sensing region 131, and the pressing portion 12 includes a portion whose cross-sectional area gradually decreases in a direction (direction a in the drawing) away from the sensing region 131. The first pressing portion 121 is defined as a portion of the pressing portion 12 that gradually decreases in cross-sectional area toward a direction away from the sensing region 131.

In the present embodiment, the sensing region 131 is set to be pressed to generate a change in electrical signal. As an embodiment, the pressure sensor 13 includes a sensing material layer and an electrode layer, which are stacked, and when one of the sensing material layer or the electrode layer is pressed, the sensing material layer or the electrode layer approaches to the other of the sensing material layer or the electrode layer, so that a contact area between the sensing material layer and the electrode layer is changed, and further, an electrical property (resistance, capacitance, impedance, or the like) is changed, so that a change of an output electrical signal is caused, and finally, a purpose of pressure sensing is achieved.

It can be understood that the cross-sectional area of the first pressing portion 121 gradually decreases toward the direction away from the sensing region 131, and when the first pressing portion 121 is pressed, the cross-sectional area of the same position of the first pressing portion 121 is gradually increased by the pressing force; and as the pressing force is released, the cross-sectional area of the first pressing portion 121 at the same position is gradually restored to the initial state as the pressing force becomes smaller. Therefore, when the first pressing portion 121 is pressed, the cross-sectional area of the first pressing portion 121 becomes gradually larger as the pressing force increases, the area of the first pressing portion 121 for transmitting force also increases gradually, and the amount of change in force sensed by the sensing area 131 also increases gradually as the force transmission area of the first pressing portion 121 increases; when the pressing force of the first pressing portion 121 is released, the cross-sectional area of the first pressing portion 121 gradually returns to the initial state as the pressing force decreases, the area of the first pressing portion 121 for transmitting the force also gradually decreases, and the amount of change in the force sensed by the sensing area 131 gradually increases as the force transmitting area of the first pressing portion 121 decreases. It can be understood that, by adopting the above arrangement, the amount of change of the force sensed by the sensing region 131 can be accurately controlled according to the amount of compression of the first pressing part 121, and thus the sensing accuracy of the button 1 can be improved; meanwhile, the first pressing portion 121 can gradually increase the force transmission area while transmitting the pressing force to the sensing area 131, so that the applied force can be well transmitted to the sensing area 131 through the first pressing portion 121 regardless of whether the force application direction is opposite to the sensing area 131. The first pressing portion 121 with the cross-sectional area gradually changing toward the direction away from the sensing area 131 is more easily compressed when being pressed, that is, the compression amount of the first pressing portion 121 with the cross-sectional area changing under the same pressing force is larger, so that the pressing touch feeling of the user when pressing the button 1 can be improved without changing the size of the trigger signal of the button 1.

Referring to fig. 1 and 2, the present invention is not limited to the corresponding arrangement of the pressing portion 12 and the sensing region 131, as long as the force can be transmitted to the sensing region 131 through the pressing portion 12. As shown in fig. 1, as an embodiment, the sensing area 131 is disposed on a surface of the pressure sensor 13 facing away from the pressing portion 12, so that when the pressure sensor 13 is pressed by the pressing portion 12, a force can be transmitted to the sensing area 131 through the pressure sensor 13; as another embodiment, as shown in fig. 2, the pressing portion 12 is disposed opposite to the sensing region 131, so that the force can be directly transmitted to the sensing region 131 through the pressing portion 12. The embodiment of the present invention is illustrated by the relative arrangement of the pressing portion 12 and the sensing region 131, but not limited thereto.

Referring to fig. 2 and 3, the installation positions of the extruding portion 12 and the pressure sensor 13 are not specifically limited in the embodiment of the present invention. As an embodiment, when one of the pressing portion 12 and the pressure sensor 13 is provided on the housing 11, the other is provided on the bearing portion 14. As shown in fig. 2, when the pressing portion 12 is provided on the housing 11, the pressure sensor 13 is provided on the bearing portion 14; as shown in fig. 3, when the pressing portion 12 is provided on the bearing portion 14, the pressure sensor 13 is provided on the housing 11.

The utility model discloses do not specifically limit to the relative position of extrusion portion 12 and sensing area 131, extrusion portion 12 can correspond any position setting of sensing area 131. Referring to fig. 3, as a preferred embodiment, the pressing portion 12 is disposed corresponding to a central position of the sensing region 131.

It can be understood that, because the pressing portion 12 directly corresponds to the sensing region 131, the pressing portion 12 can directly transmit the pressure to the sensing region 131, and then reduce the pressure applied to the non-sensing region, and the pressure applied to the non-sensing region is smaller, so that the interference to the electrical signal output by the pressure sensor 13 can be reduced, and the sensing accuracy of the pressure sensor 13 is further improved.

Referring to fig. 4, the shape of the first pressing portion 121 is not limited in the present invention, and the shape of the first pressing portion 121 may be set according to specific requirements. As shown in a of fig. 4, the first pressing part 121 may be a spherical protrusion having a circular cross section; as shown in fig. 4 b, the first pressing part 121 may also be a cone having an elliptical cross section; as shown in c of fig. 4, the first pressing part 121 may also be a boss having a polygonal cross section.

Referring to fig. 2, fig. 3 and fig. 5, as a preferred embodiment of the present invention, the first pressing portion 121 is an arc-shaped protrusion having an arc-shaped curved surface 1211. When the pressure sensor 13 is disposed on the bearing portion 14, the arc-shaped curved surface 1211 of the arc-shaped protrusion is disposed corresponding to the housing 11; when the pressure sensor 13 is disposed on the housing 11, the arc curved surface 1211 of the arc protrusion is disposed corresponding to the bearing portion 14.

It can be understood that each point of the curved surface corresponds to an orientation, and when any place of the curved surface is stressed, the force can be uniformly dispersed all around. Therefore, when the pressing portion 12 is externally applied with a force, the applied force can be well transmitted to the sensing region 131 through the first pressing portion 121 regardless of whether the force application direction is directly opposite to the sensing region 131.

Of course, in other embodiments, the first pressing portion 121 may be a protrusion having other surface shapes.

Further, in the present embodiment, in the initial state, the pressing portion 12 abuts against the pressure sensor 13. Specifically, the pressing portion 12 and the pressure sensor 13 are interposed between the housing 11 and the bearing portion 14, and the pressing portion 12 abuts against the pressure sensor 13 and presses the sensing region 131.

It can be understood that, since the pressing portion 12 collides with the sensing region 131 and presses the sensing region 131 in the initial state, the sensing region 131 is pressed in the initial state to generate the output of the electrical signal. It is understood that whether the button 1 outputs the control signal is derived from the variation of the electrical signal of the sensing region 131. That is, when the pressing force applied to the sensing region 131 is changed, the electrical signal output from the sensing region 131 is changed, and when the change amount reaches a set value, the button 1 outputs a control signal. In the present invention, since the pressing portion 12 is in contact with the sensing region 131 and presses the sensing region 131 in the initial state, the sensing region 131 can be continuously pressed to change the electrical signal output by the sensing region 131, and the pressing force at the sensing region 131 can be released to change the electrical signal output by the sensing region 131.

As an embodiment, a pressing area 111 is disposed on an outer side of the housing 11 for a user to press conveniently, when the pressing area 111 is disposed in a force-bearing direction of the sensing area 131 and is disposed corresponding to the pressing portion 12, the user can increase a pressure applied to the sensing area 131 by pressing the pressing area 111, and the pressure on the sensing area 131 changes to change at least one electrical parameter.

As another embodiment, when the pressing area 111 is disposed in a direction perpendicular to the force direction of the sensing area 131, when the user presses the pressing area 111, the pressed areas of the housing 11 are forced to approach each other, and the housings 11 far from the pressing area 111 are pressed to separate from each other, at this time, the pressing portion 12 interposed between the housing 11 and the bearing portion 14 is released to reduce the pressing force of the pressing portion 12 on the sensing area 131, so that the pressure on the sensing area 131 changes, and at least one electrical parameter is changed.

Referring to fig. 6, a button 2 is provided according to a second embodiment of the present invention, and the parts of the button 2 are the same as those of the button 1, and the advantageous effects thereof have been described in the first embodiment, and are not repeated herein. Button 2 differs from button 1 in that: in the initial state, a gap is maintained between the pressing portion 12 and the pressure sensor 13.

Referring to fig. 7, a button 3 according to a third embodiment of the present invention is provided, where the button 3 includes components in the button 1, and beneficial effects of the components are described in the first embodiment, and are not described herein again. The button 3 differs from the button 1 in that: the pressing portion 12 is further provided with a portion whose cross-sectional area is constant in a direction away from the sensing region 131. In the initial state, the portion of the pressing portion 12 having a constant cross-sectional area in a direction away from the sensing region 131 is in contact with the sensing region 131. The second pressing portion 122 is defined as a portion of the pressing portion 12 having a constant cross-sectional area in a direction away from the sensing region 131.

The embodiment of the present invention does not specifically limit the installation positions of the pressing portion 12 and the pressure sensor 13, and when the pressure sensor 13 is disposed on the bearing portion 14, the first pressing portion 121 is abutted against the housing 11, and the second pressing portion 122 is abutted against the sensing region 131; when the pressure sensor 13 is disposed on the housing 11, the first pressing portion 121 abuts against the bearing portion 14, and the second pressing portion 122 abuts against the sensing region 131. The embodiment of the present invention is exemplified by the pressure sensor 13 being disposed on the bearing portion 14, but not limited thereto.

It can be understood that, when the housing 11 presses the first pressing portion 121, the housing 11 moves toward the first pressing portion 121, and since the cross-sectional area of the first pressing portion 121 gradually decreases toward the direction away from the sensing region 131, the contact area between the first pressing portion 121 and the housing 11 is gradually increased while the housing 11 is close to the first pressing portion 121, so that the force acting on the first pressing portion 121 can be better transmitted to the second pressing portion 122. Similarly, when the housing 11 moves away from the first pressing portion 121, the contact area between the first pressing portion 121 and the housing 11 is gradually reduced, so as to better release the pressure acting on the second pressing portion 122. Since the contact area between the first pressing portion 121 and the housing 11 is gradually increased or decreased, the amount of change of the force transmitted to the sensing region 131 through the second pressing portion 122 is also gradually changed, and such an arrangement enables more precise control of the amount of change of the force sensed by the sensing region 131 according to the amount of compression of the first pressing portion 121, and has high practicability. Meanwhile, the problem of poor consistency caused by installation errors can be well avoided by controlling the extrusion force of the extrusion part 12 on the sensing area 131 in the initial state, and the reliability of the button 1 is further improved. Since the cross-sectional area of the second pressing portion 122 is kept constant in the direction away from the sensing region 131, the force acting on the second pressing portion 122 can be more accurately and unmistakably transmitted to the sensing region 131. Meanwhile, the second pressing portion 122 with the cross-sectional area kept unchanged has a smaller amount of deformation when being stressed, so that when the second pressing portion 122 presses the sensing area 131, the sensing area is not excessively pressed to the non-sensing area of the pressure sensor 13 due to the deformation, and thus, the interference of the electrical signal output by the pressure sensor 13 can be reduced, and the practicability is high. Meanwhile, the regular second pressing portion 122 is more convenient for manufacturing the pressing portion 12.

Preferably, the pressing portion 12 is integrally formed, that is, the second pressing portion 122 and the first pressing portion 121 are integrally formed, such an arrangement is more convenient for manufacturing and installing the pressing portion 12, and meanwhile, the connecting structural strength between the second pressing portion 122 and the first pressing portion 121 can be enhanced, and the second pressing portion 122 and the first pressing portion 121 are prevented from falling off.
