[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0044] The following is combined with Figures 1-10 The pressure-sensitive buttons and electronic devices provided by the utility model embodiments are described in detail through specific implementation examples and application scenarios.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model embodiment provides a pressure-sensitive button 1, including: a light guide base 11, a pressing part 12, a pressure-sensitive component 13, and an indicator light 14;

[0046] The light guide seat 11 is used to install on the main body 2 of the equipment. A groove 1101 is formed at the end of the light guide seat 11 that is away from the main body 2 of the equipment.

[0047] The pressing part 12 is used to receive pressing input. The pressing part 12 is located at one end of the light guide seat 11 away from the main body 2 of the device, and forms a receiving cavity 101 with the groove 1101.

[0048] The pressure-sensitive component 13 is electrically connected to the device body 2. The pressure-sensitive component 13 is disposed in the receiving cavity 101 and can generate a pressure-sensitive signal for controlling the device body 2 under the pressure of the pressing part 12.

[0049] The indicator light 14 is electrically connected to the main body 2 of the device. The indicator light 14 is located in the receiving cavity 101 and can emit an indicator light corresponding to the pressure-sensitive signal under the control of the main body 2 of the device. The light guide seat 11 is used to conduct the indicator light emitted by the indicator light 14 in the circumferential direction.

[0050] Understandably, the light guide base 11 includes a transparent substrate and light guide powder embedded in the transparent substrate. The light guide powder can be materials such as zinc oxide, calcium oxide, and zinc sulfide. The transparent substrate can be made of a transparent material with good light transmittance. For example, the light transmittance of the transparent material can reach more than 85%. The transparent material can be polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), and MS resin, etc.

[0051] like Figure 4 and Figure 7 As shown, a first step surface 1102 can be provided at one end of the light guide seat 11 away from the main body 2 of the device. The first step surface 1102 is provided along the circumference of the groove 1101, and the pressing part 12 can be installed based on the first step surface 1102.

[0052] like Figure 4 and Figure 8 As shown, a second step surface 1103 can be provided at one end of the light guide seat 11 facing the device body 2. The light guide seat 11 is installed in the mounting hole of the device body 2 based on the second step surface 1103. The second step surface 1103 extends circumferentially along the light guide seat 11. An insertion part can be formed in the inner area of ​​the second step surface 1103 of the light guide seat 11. The insertion part is inserted into the mounting hole.

[0053] The wall of the mounting hole can be provided with a third step surface opposite to the second step surface 1103, and the second step surface 1103 can be bonded to the third step surface by the adhesive dispensing part 17.

[0054] Since the pressure-sensitive component 13 is disposed in the receiving cavity 101 formed by the groove 1101 of the pressing part 12 and the light guide seat 11, the pressing part 12 has a pressing area corresponding to the pressure-sensitive component 13. When the pressing area of ​​the pressing part 12 is pressed, the pressing area can undergo a slight deformation under the pressing to realize the pressing input. At this time, the pressing area will transmit the pressure received to the pressure-sensitive component 13 so that the pressure-sensitive component 13 generates a pressure signal.

[0055] The pressure-sensitive signal generated by the pressure-sensitive component 13 is used to trigger the display screen 23, camera module 24 and other functional devices on the main body 2 of the device to complete the corresponding actions. For example, the pressure-sensitive signal is used to trigger the display screen 23 to enter the screen recognition mode, or to trigger the camera module 24 to flip and enter the finger reading mode.

[0056] For example, the pressing part 12 can be configured as a flat surface or a cover, and the pressing part 12 can be installed on the end of the light guide seat 11 away from the device body 2 by means of adhesive or snap-fit.

[0057] For example, the pressing part 12 can also be configured as a light shield. The pressing part 12 is used to prevent the indicator light emitted by the indicator light 14 from being emitted from the end of the light guide seat 11 away from the device body 2. Instead, the indicator light emitted by the indicator light 14 is transmitted circumferentially by the light guide seat 11. Compared with conventional light-emitting buttons, this design provides a new way of emitting light and increases the aesthetics of the overall shape of the pressure-sensitive button 1.

[0058] The indicator light 14 can be an LED light, which can emit different colors and / or brightness of indicator light according to the type of pressure signal generated by the pressure-sensitive component 13 (such as the magnitude or frequency of the pressure signal).

[0059] For example, the pressure sensing component 13 can be a pressure sensor, such as any one of a piezoresistive sensor, a strain gauge sensor, or an inductive sensor. Of course, other types of pressure sensors can also be used. This embodiment does not make specific limitations.

[0060] The pressure-sensitive button 1 shown in this utility model is configured with a pressing part 12, a pressure-sensitive component 13, and an indicator light 14 based on a light guide seat 11. The pressing part 12 can receive pressing input and transmit the received pressure to the pressure-sensitive component 13. The pressure-sensitive component 13 will generate a pressure-sensitive signal accordingly. The pressure-sensitive signal can trigger the functional devices of the device body 2 to perform corresponding functions. Under the control of the device body 2, the indicator light 14 emits an indicator light corresponding to the pressure-sensitive signal. This allows the user to quickly identify whether the corresponding function of the device body 2 is turned on, realizing human-computer interaction. Furthermore, since the indicator light 14 is set in the receiving cavity 101 formed by the groove 1101 of the pressing part 12 and the light guide seat 11, the light guide seat 11 conducts the indicator light emitted by the indicator light 14 in the circumferential direction. This ensures that the user can accurately identify the indicator light emitted by the indicator light 14, while also ensuring the aesthetic appearance of the overall shape of the pressure-sensitive button 1 based on circumferential illumination.

[0061] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the pressure-sensitive component 13 includes: a flexible circuit board 131 and at least one set of pressure-sensitive resistors 132;

[0062] The flexible circuit board 131 is used for electrical connection with the main body 2 of the device. At least a portion of the flexible circuit board 131 is attached to the pressing area of ​​the pressing part 12. The indicator light 14 is disposed on the flexible circuit board 131. At least one set of varistor 132 is disposed at the position where the flexible circuit board 131 is attached to the pressing area.

[0063] It is understandable that by setting the indicator light 14 on the flexible circuit board 131, the indicator light 14 can be fixed without the need to configure a separate signal line for connecting the indicator light 14 to the main body 2 of the device. This design realizes the integrated design of the pressure sensing component 13 and the indicator light 14.

[0064] To ensure uniform light emission along the circumference of the pressure-sensitive button 1, multiple indicator lights 14 can be provided, spaced apart along the circumference of the groove 1101, and each indicator light 14 can be an LED.

[0065] Considering that the flexible circuit board 131 has a certain degree of flexibility, a varistor 132 can be configured on the flexible circuit board 131 to detect the pressure transmitted through the pressing part 12; for example, the flexible circuit board 131 has a placement area for placing the varistor 132, the pressing part 12 is attached to a first side of the placement area, and a second side of the placement area is used to place at least one set of varistor 132.

[0066] In practical applications, in order to achieve accurate pressure detection, the varistor 132 is usually arranged in groups of four. Multiple groups of varistor 132 can be set to detect different pressing commands input by the user through the pressing part 12. For each group of varistor 132, the varistor 132 can include varistor R1, varistor R2, varistor R3 and varistor R4. The varistor R1 to R4 are interconnected on the flexible circuit board 131 to form a Wheatstone bridge structure, so that pressure can be easily detected based on the Wheatstone bridge structure.

[0067] For example, such as Figure 3 and Figure 6 As shown, at least one set of varistor 132 includes: a first set of varistor 1321 and a second set of varistor 1322; wherein, both the first set of varistor 1321 and the second set of varistor 1322 can form a Wheatstone bridge structure on the flexible circuit board 131.

[0068] The pressing area of ​​the pressing part 12 extends along a first direction, and the first group of varistor 1321 and the second group of varistor 1322 are spaced apart along the first direction. The first direction may be the length direction of the main body 2 of the device.

[0069] like Figure 1 and Figure 6 As shown, the pressing area has a first region 1201, a second region 1202 and a third region 1203 arranged sequentially along a first direction. The second region 1202 is located between the first region 1201 and the third region 1203. The first region 1201 is disposed opposite to the first group of piezoresistive resistors 1321, and the third region 1203 is disposed opposite to the second group of piezoresistive resistors 1322.

[0070] The pressing part 12 is used to receive a first type of pressing input acting on the second region 1202, and the pressure-sensitive component 13 is used to generate a first type of pressure-sensitive signal based on the first type of pressing input; wherein, the first type of pressure-sensitive signal reflects that only the second region 1202 undergoes a slight deformation, and the deformation of the second region 1202 can be detected by the first set of pressure-sensitive resistors 1321 and the second set of pressure-sensitive resistors 1322;

[0071] And / or, the pressing part 12 is used to receive a second type of pressing input that slides from the first region 1201 to the third region 1203, and the pressure-sensitive component 13 is used to generate a second type of pressure-sensitive signal according to the second type of pressing input; wherein, the first type of pressure-sensitive signal reflects the sequential slight deformation of the first region 1201, the second region 1202 and the third region 1203, the deformation of the first region 1201 can be detected by the first group of pressure-sensitive resistors 1321, and the deformation of the third region 1203 can be detected by the second group of pressure-sensitive resistors 1322.

[0072] For example, when a user presses the second area 1202 once to perform a first type of press input, the pressure-sensitive component 13 generates a first type of pressure-sensitive signal A to trigger the display screen 23 of the device body 2 to enter the screen recognition mode. At this time, the device body 2 controls the indicator light 14 to emit a red indicator light. The user can use their hand or stylus to select content on the display screen 23, and the large model of the device body 2 will recognize and interpret the selected content. When the user presses the surface of the pressing part 12 and slides it from left to right in the first direction to perform a second type of press input, the pressure-sensitive component 13 generates a second type of pressure-sensitive signal A to trigger the device body 2 to recognize the full-screen content displayed on the display screen 23 (e.g., using large model recognition). The large model can extract the full-screen content displayed on the display screen 23, including but not limited to generating an article summary and recognizing screen image content.

[0073] For example, when the user presses the second area 1202 twice in succession to perform the first type of press input, the pressure-sensitive component 13 generates the first type of pressure-sensitive signal B to trigger the device body 2 to complete the following three control commands: (1) the control indicator 14 emits a blue indicator light; (2) the control device body 2's camera module 24 flips and enters the finger reading mode; when the user presses the second area 1202 again to perform the first type of press input, the pressure-sensitive component 13 generates the first type of pressure-sensitive signal C again to trigger the device body 2's camera module 24 to take a picture, and the user can correct the paper work; finally, when the user presses the surface of the pressing part 12 and slides from left to right along the first direction to perform the second type of press input, the pressure-sensitive component 13 generates the second type of pressure-sensitive signal B, which is used to trigger the device body 2's camera module 24 to exit the finger reading mode.

[0074] For example, when a user presses the second area 1202 once to perform a first type of press input, the second area 1202 undergoes a greater deformation than the single press described above. The pressure-sensitive component 13 generates a first type of pressure-sensitive signal D to trigger the device body 2 to complete the following two control commands: (1) the control indicator 14 emits a green indicator light; (2) the control device body 2 enters the AI ​​question-and-answer mode, and the user can ask and answer questions with the large model of the control device through voice interaction; when the user presses the surface of the pressing part 12 and slides it from left to right along the first direction to perform a second type of press input, the pressure-sensitive component 13 generates a second type of pressure-sensitive signal C, which is used to trigger the device body 2 to generate a summary of the dialogue record.

[0075] In some embodiments, such as Figure 2 , Figure 4 and Figure 5As shown, the pressure-sensitive button 1 also includes a reinforcing plate 15, which is disposed in the receiving cavity 101 and located between the portion of the flexible circuit board 131 corresponding to the pressing area and the bottom of the groove 1101; wherein, the reinforcing plate 15 is provided with a clearance area 1501, which is used to accommodate the varistor 132.

[0076] Understandably, the reinforcing plate 15 can be made of steel sheet. The reinforcing plate 15 is used to provide support on the side of the flexible circuit board 131 away from the pressing part 12, so as to prevent the pressing part 12 and the corresponding structure from undergoing irreversible bending or even breakage due to excessive pressing force.

[0077] An opening can be provided on the reinforcing plate 15 to form a clearance area 1501. By providing a clearance area 1501 for accommodating the varistor 132, it is convenient to provide deformation space for the varistor 132.

[0078] In the case where multiple sets of varistors 132 are arranged on the flexible circuit board 131, multiple clearance areas 1501 are provided on the reinforcing plate 15, and the multiple sets of varistors 132 are arranged opposite to the multiple clearance areas 1501.

[0079] In some embodiments, such as Figure 2 and Figure 4 As shown, the pressure-sensitive button 1 also includes an adhesive layer 16, and a reinforcing plate 15 is connected to the bottom of the groove 1101 via the adhesive layer 16, so that the reinforcing plate 15 is securely attached to the bottom of the groove 1101 corresponding to the light guide base 11 based on the adhesive layer 16. The adhesive layer 16 and the reinforcing plate 15 have corresponding external shapes.

[0080] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, the light guide seat 11 is provided with a through hole 1100, which is connected to the groove 1101; the first end of the flexible circuit board 131 is provided with an indicator light 14 and a pressure-sensitive resistor 132 on the side away from the pressing part 12, the middle part of the flexible circuit board 131 is inserted through the through hole 1100, and the second end of the flexible circuit board 131 is connected to the device body 2 through the sealing member 201.

[0081] It is understandable that the device body 2 is provided with mounting holes, and the end of the light guide seat 11 facing the device body 2 is installed in the mounting hole through the dispensing part 17. The second end of the flexible circuit board 131 passes through the mounting hole, and the flexible circuit board 131 and the hole wall of the mounting hole are sealed by the sealing part 201. This design can form a good waterproof seal between the pressure-sensitive button 1 and the device body 2.

[0082] The seal 201 can be a silicone plug, which is embedded in the mounting hole, and the flexible circuit board 131 passes through the silicone plug.

[0083] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the pressing part 12 includes: an elastic pressure plate 121 and an outer ring 122;

[0084] The elastic pressure plate 121 is arranged opposite to the groove of the groove 1101. The elastic pressure plate 121 is used to receive the pressing input. The outer ring 122 is arranged along the circumference of the elastic pressure plate 121 and is connected to the light guide seat 11.

[0085] It is understood that the elastic pressure plate 121 can be made of elastic plastic sheet, which can undergo slight deformation when receiving a pressing input in order to transmit the deformation to the pressure-sensitive component 13.

[0086] Meanwhile, the elastic pressure plate 121 and the outer ring 122 can be configured to be connected, with the outer ring 122 providing support and protection for the elastic pressure plate 121 around its perimeter. In practical applications, the outer ring 122 can be made of metal, which serves both decorative and protective functions, preventing the pressure-sensitive button 1 from being impacted when dropped.

[0087] like Figure 4 As shown, the outer ring 122 can also be installed on the first step surface 1102 of the light guide seat 11. The outer ring 122 blocks the light at the end of the light guide seat 11 away from the main body 2 of the device, ensuring that the indicator light emitted by the indicator light 14 is transmitted along the circumference of the light guide seat 11.

[0088] In some embodiments, along the height direction of the light guide base 11, the top surface height of the outer ring 122 is higher than the top surface height of the elastic pressure plate 121. This design can prevent users from accidentally touching the elastic pressure plate 121, while protecting the pressure-sensitive button 1 in the event of a drop.

[0089] In some embodiments, such as Figure 9 and Figure 10 As shown, this utility model embodiment also provides an electronic device, including: a device body 2 and a pressure-sensitive button 1 as described above. The pressure-sensitive button 1 is disposed on the device body 2, and the pressure-sensitive component 13 and the indicator light 14 are electrically connected to the device body 2 respectively.

[0090] It is understandable that the electronic device can be educational devices such as learning machines and e-readers that are well-known in the field. The device itself can be placed on a horizontal table by a stand, and the angle of the device itself relative to the horizontal plane can be adjusted by the stand to meet the homework needs of students of different ages.

[0091] Since the electronic device includes a pressure-sensitive button 1, and the specific structure of the pressure-sensitive button 1 is as described in the above embodiments, the electronic device of this embodiment includes all the technical solutions of the above embodiments. Therefore, all the beneficial effects achieved by all the technical solutions of the above embodiments will not be described in detail here.

[0092] In some embodiments, such as Figure 9 As shown, the main body 2 of the device includes a housing 21 and a circuit board 22, a display screen 23 and a camera module 24 disposed on the housing 21;

[0093] The camera module 24 is rotatably mounted on the top edge of the housing 21, the display screen 23 is mounted on the front side of the housing 21, the pressure-sensitive component 13 is electrically connected to the circuit board 22, and the circuit board 22 is electrically connected to the indicator light 14, the display screen 23 and the camera module 24 respectively.

[0094] It is understandable that circuit board 22 can be a PCB board and display screen 23 can be a touch screen.

[0095] The camera module 24 is configured to be located on the back of the housing 21. The camera module 24 may include a drive motor, a flip base, and a camera. The drive motor and the flip base are connected, and the camera is mounted on the flip base. The drive motor can drive the flip base to flip the camera from the rear to the front of the device body 2, thereby realizing the flipping function of the camera module 24.
