[0034] To make the objectives, technical solutions, and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Examples of embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] This utility model discloses a pressure touch button, please refer to Figures 1 to 8 , including a main body 10, with elastic beams 20 extending outward on both sides of the bottom of the main body 10, and a strain sensing unit 30 is connected to each of the two elastic beams 20 in the thickness direction. The strain sensing unit 30 includes four strain sensing resistors 31 arranged in a quadrilateral.

[0036] The invention comprises a main body 10, with elastic beams 20 extending outward and elastically deformable on both sides of the bottom of the main body 10, and a strain sensing unit 30 connected in the thickness direction of the elastic beam 20, wherein the strain sensing unit 30 includes four strain sensing resistors 31 arranged in a quadrilateral. When pressure is applied to the main body 10, the pressure is transmitted from the main body 10 to the elastic beam 20, causing the elastic beam 20 to deform. Since there are elastic beams 20 on both sides of the bottom, the different positions of the applied pressure will cause the two elastic beams 20 to deform differently, and the values ​​of the inductive strain units installed on the elastic beams 20 will also be different, thereby realizing the functions of pressure recognition and touch sensing. Compared with the prior art, the pressure touch key disclosed in this application can achieve the purpose of simple and compact structure.

[0037] Specifically, the strain sensing unit 30 includes four strain sensing resistors 31 arranged in a quadrilateral, thereby avoiding the use of independent pressure sensors, reducing the size of the pressure touch key, and achieving the purpose of making it compact.

[0038] The main body 10 may be directly used to bear the pressure applied by the user, or other structures for bearing the pressure applied by the user may be installed on the main body 10 .

[0039] It should be noted that "extending outward" refers to extending toward a side away from the main body 10. Elastic beams 20 are provided on both sides of the bottom of the main body 10, i.e., there are two elastic beams 20. Furthermore, strain sensing units 30 are provided in the thickness direction of the elastic beams 20, enabling them to sense deformation of the elastic beams 20 and thus perform normal recognition.

[0040] In some embodiments, the strain sensing unit 30 is disposed on the elastic beam 20 close to the body 10 .

[0041] Specifically, in order to enable the strain sensing unit 30 to obtain a better sensing signal, the strain sensing unit 30 is disposed on the elastic beam 20 close to the body 10 . This is because the deformation of the elastic beam 20 is greater at the position where the elastic beam 20 is close to the body 10 .

[0042] Obviously, the strain sensing unit can also be set at other positions of the elastic beam. In addition, in addition to the position of the strain sensing unit affecting its sensing signal, the ratio between the distance between the four strain sensing resistors and the length of the elastic beam also determines the strength of the sensing signal.

[0043] In some embodiments, please refer to Figure 1 、 Figure 5 and Figure 6The main body 10 includes a pressing portion 11 and a connecting portion 12 . The pressing portion 11 , the connecting portion 12 and the elastic beam 20 are sequentially connected in the thickness direction. The length of the pressing portion 11 is greater than the length of the connecting portion 12 .

[0044] Specifically, the body 10 includes a pressing portion 11 and a connecting portion 12. The pressing portion 11, the connecting portion 12, and the elastic beam 20 are sequentially connected in the thickness direction. The pressing portion 11 is connected to the elastic beam 20 via the connecting portion 12, which makes the connection relationship more reasonable, making it easier to select a material for the connecting portion 12 that is easy to connect with the pressing portion 11 and the elastic beam 20, and also facilitates more design options for the connecting portion 12. In addition, the length of the pressing portion 11 is greater than the length of the connecting portion 12. On the one hand, it allows the user to press a larger pressing area, and on the other hand, it also allows the elastic beam 20 to undergo greater elastic deformation.

[0045] In some embodiments, please refer to Figure 2 、 Figure 7 and Figure 8 The main body 10 includes a pressing portion 11 and a connecting portion 12 . The pressing portion 11 and the elastic beam 20 are connected in the thickness direction, and the connecting portion 12 is connected between the two elastic beams 20 .

[0046] It should be noted that, in order to make the structure of the pressure touch key simpler and more compact and further reduce the thickness of the pressure touch key, the pressing portion 11 and the elastic beam 20 are connected in the thickness direction, and the connecting portion 12 is used to connect the two elastic beams 20.

[0047] In some embodiments, the strain sensing unit 30 is disposed on a side of the elastic beam 20 away from the body 10 .

[0048] Specifically, the strain sensing unit 30 is arranged on the side of the elastic beam 20 away from the main body 10, so that after the pressure touch button is installed, the strain sensing unit 30 is located on the inner side of the electronic device, thereby better protecting the strain sensing unit 30 and preventing it from being easily damaged.

[0049] In some embodiments, please refer to Figure 5 and Figure 7 One end of the elastic beam 20 away from the body 10 is bent to form a bent clamping portion 21 .

[0050] Specifically, the elastic beam 20 is bent at one end away from the body 10 to form a bent snap-fit ​​portion 21. The provision of the bent snap-fit ​​portion 21 allows the pressure-sensitive touch button to be securely connected to the electronic device without requiring any other connecting or fixing structures. Furthermore, because the elastic beam 20 is inherently elastic, the bent snap-fit ​​portion 21 also exhibits elasticity, enabling a better snap-fit ​​to the electronic device. Therefore, with the bent snap-fit ​​portion 21 provided, the elastic beam 20 not only performs the function of elastically deforming under pressure but also functions as a connection to the electronic device.

[0051] In some embodiments, please refer to Figure 6 and Figure 8 The elastic beam 20 is connected with a clamping block 22 in the thickness direction.

[0052] Specifically, the elastic beam 20 is connected to the snap-fit ​​block 22 in the thickness direction. When the pressure touch button is installed, the snap-fit ​​block 22 and the elastic beam 20 can be loaded together on the electronic device. Since the elastic beam 20 has a certain elasticity, it is easy to achieve interference fit when loaded together with the snap-fit ​​block 22, and the snap-fit ​​is firm, thereby achieving the loading of the pressure touch button.

[0053] In some embodiments, four strain sensing resistors 31 are arranged in a rectangular shape.

[0054] It should be noted that the four strain sensing resistors 31 are distributed in a rectangular shape, thereby avoiding the increase in calculation amount that occurs when the four strain sensing resistors 31 are arranged in other quadrilaterals, making the recognition of pressure and touch more sensitive and stable.

[0055] In some embodiments, a keycap 13 is mounted on the body 10 for a user to press.

[0056] In some embodiments, a sensing layer for receiving external signals is provided in the thickness direction of the body.

[0057] Specifically, the sensing layer can be a structural unit for receiving external signals, such as a capacitor layer, an ultrasonic sensor layer, and a photoelectric sensor layer. When the main body has a pressing portion and a connecting portion, and the pressing portion has a keycap, the sensing layer can be set above the keycap, between the keycap and the pressing layer, between the pressing layer and the connecting layer, or below the connecting layer. The specific location of the sensing layer needs to be determined according to the properties of the sensing layer itself and the type of received signal. For example, when the sensing layer is a capacitor layer, the sensing layer can be set between the keycap and the pressing layer. This can avoid direct contact between the capacitor layer and the human hand, prevent hand sweat or dust from affecting the use of the capacitor layer, and also make it easier to receive the capacitor signal.

[0058] The utility model also discloses an electronic device, comprising the above-mentioned pressure touch button.

[0059] By installing the pressure touch button, the electronic device can have a larger installation space and at the same time make its overall structure more compact and achieve a smaller volume.

[0060] In some embodiments, please refer to Figures 5 to 8 The electronic device includes a frame 40 having an interlocking slot 41 formed by an upper mounting portion 42 and a lower mounting portion 43 spaced apart. The elastic beam 20 is disposed in the interlocking slot 41 , and an edge of the upper mounting portion 42 is disposed close to the body 10 .

[0061] Specifically, the frame 40 has an interlocking slot 41, and the edge of the mounting portion 42 on the interlocking slot 41 is set close to the main body 10. On the one hand, it provides a simple installation method, and on the other hand, it can effectively isolate dust and liquid from entering the interior of the electronic device through the pressure touch buttons, thereby playing a waterproof and dustproof role.
