[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0033] According to one embodiment of the present application, a key is provided. Figures 1 to 5 As shown, the key comprises a support plate 1, a touch component 2 and a piezoelectric sensing element 3. The touch component 2 is elastically connected to the support plate 1, and the touch component 2 comprises a touch panel 21, and the touch panel 21 is suspended relative to the support plate 1. The piezoelectric sensing element 3 is located between the touch panel 21 and the support plate 1, one end of the piezoelectric sensing element 3 is connected to the support plate 1, and the other end is in contact with the touch panel 21, and the piezoelectric sensing element 3 is configured to vibrate according to the touch signal of the touch panel 21, so as to drive the touch panel 21 to vibrate.

[0034] In this example, the piezoelectric sensing element 3 is located between the touch panel 21 and the support plate 1, which can improve the installation stability of the piezoelectric sensing element 3. One end of the piezoelectric sensing element 3 is connected to the support plate 1, and the other end is in contact with the touch panel 21. The touch component 2 is elastically connected to the support plate 1, and the touch panel 21 is suspended relative to the support plate 1. The elastic element 4 can provide a certain amount of floating, so that the touch panel 21 can better transmit vibration and provide clear vibration.

[0035] In this example, the touch panel 21 can be electrically connected to the MCU (Microcontroller Unit), and the user can implement key command operation by touching or pressing the character area 211 on the touch panel 21. The touch panel 21 can be configured to generate a signal by the user sliding along the touch panel 21, or can be configured to generate a signal by two-finger touch or three-finger touch. Those skilled in the art can set it according to actual conditions, and no specific limitation is made here.

[0036] In this example, the piezoelectric sensing element 3 is configured to vibrate according to the touch signal of the touch panel 21, thereby driving the touch panel 21 to vibrate, so as to remind the user that the touch panel 21 has correctly touched the button, and can perform a press touch operation. The touch panel 21 can send instructions according to the user's press. That is, the touch panel 21 and the piezoelectric sensing element 3 can both be electrically connected to the MCU (Microcontroller Unit). When the touch panel 21 is touched or pressed by the user, it can generate a touch signal and transmit the touch signal to the MCU. After receiving the touch signal, the MCU applies a voltage to the piezoelectric sensing element 3, so that the piezoelectric sensing element 3 generates an inverse piezoelectric effect, thereby generating vibration and driving the touch panel 21 to vibrate, so as to provide feedback to the user. Moreover, when the user touches or presses the touch pad 21, pressure can be applied to the piezoelectric sensing element 3, so that the piezoelectric sensing element 3 produces a positive piezoelectric effect, thereby transmitting an electrical signal to the MCU, thereby cooperating with the touch pad 21 to transmit signals to the MCU to improve the stability and reliability of the MCU receiving signals.

[0037] In this example, the piezoelectric sensing element 3 may be piezoelectric ceramics or other types of piezoelectric crystals, and those skilled in the art may determine the method based on actual conditions, and no specific limitation is made herein.

[0038] In this example, the piezoelectric sensing element 3 can be bonded to the support plate 1. The touch panel 21 can be a square plate, and is opposite to the central area of ​​the touch panel 21, so as to drive the touch panel 21 to vibrate uniformly as a whole. Alternatively, a plurality of piezoelectric sensing elements 3 can be provided, and the plurality of piezoelectric sensing elements 3 are arranged at intervals, so as to improve the vibration effect, and enable the touch panel 21 to vibrate uniformly as a whole, providing clearer tactile feedback. For example, two, three, four or five piezoelectric sensing elements 3 can be provided, and those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0039] In one example, the button also includes an elastic member 4, and the touch component 2 also includes a connector, one end of the connector is connected to the touch panel 21, one end of the elastic member 4 is connected to the support plate 1, and the other end is connected to the connector.

[0040] In this example, one end of the connecting member is connected to the touch panel 21, and the other end is connected to the elastic member 4, and the other end of the elastic member 4 is connected to the support member. The touch panel 21 can be elastically connected to the support plate 1 through the elastic member 4. There is a gap between the touch panel 21 and the support plate 1, and the piezoelectric sensing member 3 is arranged in the gap. For example, one end of the elastic member 4 abuts against the support plate 1, and the other end abuts against the connecting member. When the piezoelectric sensing member 3 drives the touch panel 21 to vibrate, the touch panel 21 can have a certain amount of floating, thereby providing a clearer vibration sense for the user to improve the user's experience effect.

[0041] In an example, Figures 2 to 4 As shown, the elastic member 4 is located at a side of the support plate 1 away from the touch panel 21 , and one end of the connecting member is sequentially passed through the support plate 1 and the elastic member 4 .

[0042] like Figure 3 As shown, in this example, the support plate 1 is provided with a first through hole 11, and the elastic member 4 is provided on the side of the support plate 1 away from the touch panel 21, and corresponds to the first through hole 11. One end of the connector is connected to the touch panel 21, and the other end can be provided with the first through hole 11 and the elastic member 4. That is, the elastic member 4 can be sleeved on the connector. One end of the elastic member 4 is against the support plate 1, and the other end can be against the connector. The piezoelectric sensor 3 is located between the support plate 1 and the touch panel 21, and the side of the piezoelectric sensor 3 away from the support plate 1 can support the touch panel 21, thereby improving the reliability of the contact between the touch panel 21 and the piezoelectric sensor 3, so that the touch panel 21 and the piezoelectric sensor 3 are in closer contact. In addition, the elastic member 4 is provided on the side of the support plate 1 away from the touch panel 21, which is conducive to reducing the gap between the support plate 1 and the touch panel 21, so that the overall structure of the key can be more compact.

[0043] In this example, the connecting member includes a fastener 22, one end of which can be inserted into the elastic member 4 and screwed to the touch panel 21, and one end of the elastic member 4 abuts against the fastener 22. The fastener 22 can extend into the first through hole 11 from the end of the support plate 1 away from the touch panel 21, and be screwed to the touch panel 21. The elastic member 4 is located on the side of the support plate 1 away from the touch panel 21, and the elastic member 4 is sleeved on the fastener 22. One end of the elastic member 4 abuts against the support plate 1, and the other end abuts against the head of the fastener 22. For example, the fastener 22 can be a bolt, etc., the bolt head is used to tighten the bolt, and the end of the elastic member 4 away from the support plate 1 can abut against the bolt head. Of course, the specific type of the fastener 22 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0044] like Figure 4As shown, in this example, the connecting member further includes a connecting rod 23, one end of which is connected to the touch panel 21. For example, one end of the connecting rod 23 can be integrally formed with the touch panel 21. The other end of the connecting rod 23 can extend into the first through hole 11. The connecting rod 23 is provided with a screw hole, and one end of the fastener 22 can be screwed into the screw hole of the connecting rod 23.

[0045] In this example, the outer diameter of the connecting rod 23 matches the inner diameter of the first through hole 11, so that the connecting rod 23 can slide in the first through hole 11, and the first through hole 11 can position and guide the connecting rod 23, thereby reducing the shaking of the touch panel 21. For example, the piezoelectric sensing element 3 can drive the touch panel 21 to vibrate up and down, and the connecting rod 23 and the first through hole 11 are conducive to reducing the left and right shaking of the touch panel 21, thereby improving the stability and reliability of the key.

[0046] In one example, the connecting member and the elastic member 4 are provided in plurality, and each of the connecting members is connected to a corresponding elastic member 4 .

[0047] In this example, the button is provided with a plurality of elastic members 4, and the touch component 2 is also provided with a plurality of connecting members, that is, the number of connecting members and elastic members 4 can be equal, and each of the connecting members is correspondingly connected to one elastic member 4, thereby improving the stability of the touch panel 21 assembly to further reduce the shaking of the touch panel 21.

[0048] For example, the touch panel 21 is a rectangular plate structure, and four connectors are provided, and the four connectors are respectively located at the four corners of the touch panel 21. Of course, the touch panel 21 can also be other structures, such as a circle or other irregular shapes. The number of connectors can also be set to other numbers, for example, two, three or five connectors can be provided. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0049] In an example, Figure 4 and Figure 5 As shown, the elastic member 4 includes a supporting portion 41 and an elastic portion 42 connected to the supporting portion 41 , the supporting portion 41 abuts against the supporting plate 1 , and one end of the elastic portion 42 away from the supporting portion 41 abuts against the connecting member.

[0050] like Figure 4 and Figure 5As shown, in this example, the support portion 41 of the elastic member 4 is suitable for abutting against the support plate 1, one end of the elastic portion 42 is connected to the support portion 41, and the other end is suitable for abutting against the connecting member, so as to provide elastic force for the touch panel 21. The elastic member 4 can improve the stability of the elastic member 4 by setting the support portion 41 to abut against the support plate 1, thereby further preventing the touch panel 21 from shaking, so as to improve the stability of the touch assembly 2. For example, the support portion 41 can be a plate body, and one end of the support portion 41 along the thickness direction can abut against the support plate 1.

[0051] In an example, Figure 3 and Figure 5 As shown, the support portion 41 and the elastic portion 42 are both annular structures, and the outer diameter of the support portion 41 is greater than the outer diameter of the elastic portion 42 .

[0052] like Figure 3 and Figure 5 As shown, the support portion 41 may be an annular plate, which is beneficial to increase the contact area between the support portion 41 and the support plate 1, thereby facilitating the improvement of the stability of the elastic member 4. The elastic portion 42 may be integrally formed with the support plate 1, that is, the elastic portion 42 is provided with an annular flange outwardly from the opening at one end of the support plate 1 to form the support portion 41. Alternatively, the elastic portion 42 may also be connected to the support portion 41 by welding or the like. Those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0053] In one example, the outer diameter of the elastic portion 42 gradually decreases from one end of the elastic portion 42 connected to the support portion 41 to the other end.

[0054] In this example, the first end of the elastic member 4 is adapted to abut against the support plate 1, and the second end of the elastic member 4 opposite to the first end is adapted to abut against the connection. From the first end to the second end, the outer diameter of the elastic member 4 gradually decreases. That is, the elastic member 4 as a whole can be a conical or truncated cone structure, which is conducive to further improving the stability of the elastic member 4.

[0055] For example, Figure 4 and Figure 5 As shown, one end of the elastic part 42 is connected to the support part 41, and the outer diameter of the elastic part 42 gradually decreases from the one end of the elastic part 42 connected to the support part 41 to the other end. That is, the elastic part 42 is a truncated cone structure. The hollow setting of the elastic part 42 is conducive to providing better elasticity.

[0056] In an example, Figure 4 and Figure 5 As shown, an abutment portion 43 is provided at one end of the elastic portion 42 away from the supporting portion 41 , the connecting member is passed through the abutment portion 43 , and the abutment portion 43 abuts against the connecting member.

[0057] like Figure 4 and Figure 5 As shown, the abutment portion 43 is arranged at one end of the elastic portion 42 away from the support portion 41, and a second through hole 431 is arranged along the thickness of the abutment portion 43, and one end of the connecting member can be inserted into the second through hole 431. The abutment portion 43 can abut against the connecting member. The abutment portion 43 can be an elastic plate, and the connecting member abuts against the abutment portion 43, so as to provide elasticity for the touch panel 21.

[0058] In this example, the elastic portion 42 is provided with the abutment portion 43, and the abutment portion 43 is provided with the second through hole 431, so as to reduce the volume of the connecting member. For example, the connecting member is a fastener 22 such as a bolt, and by providing the abutment portion 43, the area of ​​the bolt head can be reduced, which is conducive to the tightening operation of the bolt.

[0059] In this example, the elastic member 4 is made of spring steel material. Spring steel has excellent mechanical properties (such as elastic limit, strength limit, yield strength ratio), anti-elasticity (i.e., anti-elasticity, also known as anti-relaxation), fatigue performance, hardenability, and physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). Of course, the specific material of the elastic member 4 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0060] According to a second aspect of the present invention, an electronic device is provided. The electronic device includes a key of the above embodiment. The key includes a support plate 1, a touch component 2 and a piezoelectric sensor 3. Among them, the touch component 2 is elastically connected to the support plate 1, and the touch component 2 includes a touch panel 21, and the touch panel 21 is suspended relative to the support plate 1. The piezoelectric sensor 3 is located between the touch panel 21 and the support plate 1, one end of the piezoelectric sensor 3 is connected to the support plate 1, and the other end is in contact with the touch panel 21, and the piezoelectric sensor 3 is configured to be able to vibrate according to the touch signal of the touch panel 21 to drive the touch panel 21 to vibrate. The piezoelectric sensing element 3 is located between the touch panel 21 and the support plate 1, which can improve the installation stability of the piezoelectric sensing element 3. One end of the piezoelectric sensing element 3 is connected to the support plate 1, and the other end is in contact with the touch panel 21. The touch component 2 is elastically connected to the support plate 1, and the touch panel 21 is suspended relative to the support plate 1. The elastic element 4 can provide a certain amount of floating, so that the touch panel 21 can better transmit vibration and provide clear vibration.

[0061] In this example, the electronic device may be an electrical appliance, a car or an engineering machine, etc. The button of the present application may be used as an electronic device switch button, etc. Of course, the specific type of the electronic device may be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0062] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0063] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
