[0027] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] As mentioned above, the touchpad is a flat plate arranged on the C shell of the laptop computer. The touchpad on the laptop computer can identify touch commands and press commands. When the user's finger slides on the touch area on the touchpad, the cursor in the laptop computer can be moved. When the user's finger presses on the touchpad, the touchpad can identify the press command to make the laptop computer perform the corresponding operation. The existing touchpad adopts a mechanical press structure in a half-domain press form or a single button form to identify the press command, for example: Figure 1 is a schematic diagram of a touch panel in the form of a single button provided in an embodiment of the present application, such as Figure 1 As shown, the single-button touchpad includes two buttons, and the user inputs the pressing command through the two buttons. Specifically, the left button 102 can simulate the left button of the mouse, and the right button 103 can simulate the right button of the mouse. However, the single-button form will occupy the area of ​​the non-touch area 101 of the touchpad, reducing the area of ​​the touch area 101, and the half-domain pressing form requires pressing at a specific position to recognize the pressing command, for example: the half-domain pressing form requires pressing at the lower left corner to simulate the left button of the mouse, and pressing at the lower right corner to simulate the right button of the mouse, so the existing touchpad user experience is poor.

[0031] The present application provides a press detection device, which includes a circuit board, a bracket and a sensor. When the press detection device receives a press operation, the elastic arm generates elastic deformation, and the sensor can generate a press signal when the elastic arm generates elastic deformation. Therefore, the press signal can be transmitted to the control unit through the circuit board to realize the recognition of the user's press operation. Therefore, compared with the touch pad with a single button form in the prior art, the touch area is larger. Since the press position is not limited, the press signal can be generated when the press detection device receives a press operation. Therefore, compared with the touch pad with a half-domain press form in the prior art, the user can press anywhere without pressing at a specific position, thereby improving the user experience.

[0032] Figure 2 is a schematic diagram of a pressure detection device provided in an embodiment of the present application. The pressure detection device 200 is applied to electronic equipment, such as Figure 2 As shown, the press detection device 200 includes: a circuit board 202, a bracket 203 and a sensor 204, the bracket 203 is fixed on the housing 301 of the electronic device, the bracket 203 includes a bracket body 2031 and a plurality of elastic arms 2032 arranged on the bracket body, and the bracket body 2031 abuts against the circuit board 202.

[0033] When the press detection device 200 receives a press operation, the circuit board 202 drives the bracket body 2031 to move, causing the elastic arm 2032 to produce elastic deformation. The sensor 204 can generate a press signal when the elastic arm 2032 produces elastic deformation, and transmit the press signal to the circuit board 202. The circuit board 202 can transmit the press signal to the control unit, and the control unit identifies the press operation based on the press signal.

[0034] The bracket 203 includes a bracket body 2031 and a plurality of elastic arms 2032. The bracket body 2031 and the elastic arms 2032 are integrally formed. The bracket body 2031 can be stamped to obtain a plurality of elastic arms 2032 arranged on the bracket body 2031. In one example, the bracket 203 can include at least four elastic arms 2032. The at least four elastic arms 2032 can be evenly arranged at the four corners of the bracket body 2031, so that the elastic arms 2032 can be elastically deformed when the pressure detection device 200 is pressed in any direction. In one example, Figure 2 As shown, the bracket body 2031 can be bonded to the circuit board 202 through the second adhesive layer 402 .

[0035] It should be noted that the multiple elastic arms 2032 can be evenly distributed on the long side and the short side of the bracket body 2031, thereby achieving balanced force on the bracket 203. The number of elastic arms 2032 can be set as needed, and the specific number is not limited here. In one example, the bracket 203 can be made of metal, and in another example, the bracket 203 can be made of plastic. The bracket 203 can be fixed to the housing 301 of the electronic device by screws, clamping, etc., and the specific fixing method is not limited here.

[0036] When the press detection device 200 receives a press operation, the elastic arm 2032 undergoes elastic deformation. For example, when a finger presses, the circuit board 202 drives the bracket body 2031 to move relative to the elastic arm 2032, causing the elastic arm 2032 to undergo elastic deformation. When the elastic arm 2032 undergoes elastic deformation, the sensor 204 generates a press signal. In one example, the press signal may be a square wave signal. After the circuit board 202 receives the press signal sent by the sensor 204, the press signal is transmitted to the control unit. The control unit may identify the press signal and perform a press operation according to the press signal. In one example, the control unit may be a press detection chip disposed on the circuit board 202, a touch chip disposed on the circuit board 202, or a processor of an electronic device, etc.

[0037] In an embodiment of the present application, the press detection device 200 includes: a circuit board 202, a bracket 203 and a sensor 204. When the press detection device 200 receives a press operation, the elastic arm 2032 generates elastic deformation, and the sensor 204 can generate a press signal when the elastic arm 2032 generates elastic deformation. The press signal can be transmitted to the control unit through the circuit board 202 to realize the recognition of the user's press operation. Therefore, compared with the touch pad with a single button form in the prior art, the touch area is larger. Since the press position is not limited, a press signal can be generated when the press detection device receives a press operation. Therefore, compared with the touch pad with a half-domain press form in the prior art, the user can press anywhere without pressing at a specific position, thereby improving the user experience.

[0038] Figure 3 is a schematic diagram of the structure of a bracket provided in an embodiment of the present application, such as Figure 3 As shown, the first end of the elastic arm 2032 is connected to the bracket body 2031, the second end of the elastic arm 2032 extends outside the bracket body 2031, and the second end of the elastic arm 2032 is suspended, wherein in a direction parallel to the circuit board 202, the elastic arm 2032 is at least partially parallel to the bracket body 2031.

[0039] A plurality of elastic arms 2032 are connected to the bracket body 2031, and the first ends of the plurality of elastic arms 2032 are connected to the bracket body 2031. In one example, the first ends of the elastic arms 2032 can be connected to the outer edge of the bracket body 2031, and the second ends of the plurality of elastic arms 2032 extend to the outside of the bracket body 2031, extending out of the bracket body 2031 to form the elastic arms 2032.

[0040] In the embodiment of the present application, the first end of the elastic arm 2032 is connected to the bracket body 2031, the second end of the elastic arm 2032 extends to the outside of the bracket body 2031, and the second end of the elastic arm 2032 is suspended in the air. Therefore, when the circuit board 202 drives the bracket body 2031 to move, the elastic arm 2032 can produce elastic deformation, thereby ensuring that the sensor can generate a press signal.

[0041] In one possible implementation, Figure 2 As shown, the second ends of multiple elastic arms 2032 are fixed on the housing 301 of the electronic device, and the circuit board 202 is bonded to the bracket body 2031. When the press detection device 200 receives a press operation, the circuit board 202 drives the bracket body 2031 to move relative to the elastic arm 2032, and the elastic arm 2032 produces elastic deformation.

[0042] The plurality of elastic arms 2032 are fixed to the housing 301 of the electronic device. In one example, the plurality of elastic arms 2032 can be snap-fitted to the housing 301 of the electronic device. In another example, Figure 2 As shown, the multiple elastic arms 2032 can be fixed to the housing 301 of the electronic device by screws, and the specific fixing method is not limited in the embodiment of the present application.

[0043] One side of the circuit board 202 is bonded to the bracket body 2031, for example, by Figure 2 The second adhesive layer 402 in the press detection device 200 is bonded. When the press detection device 200 receives a press operation, the circuit board 202 applies a force along the pressing direction to the bracket body 2031. The circuit board 202 drives the bracket body 2031 to move downward. Since the elastic arm 2032 is fixed on the housing 301 of the electronic device, the bracket body 2031 moves relative to the fixed elastic arm 2032, causing the elastic arm 2032 to produce elastic deformation.

[0044] In the embodiment of the present application, multiple elastic arms 2032 are fixed on the housing 301 of the electronic device, and the bracket body 2031 is bonded to the circuit board 202. When the press detection device 200 receives a press operation, the circuit board 202 drives the bracket body 2031 to move relative to the elastic arms 2032, so that when the press detection device 200 receives a press operation, the elastic arms 2032 can be elastically deformed. Since the bracket 203 is fixed to the housing 301 of the electronic device through multiple elastic arms 2032, and the circuit board 202 is bonded to the bracket body 2031, the circuit board 202 can be fixed in the electronic device through the bracket 203. Since elastic deformation is generated by the elastic arms 2032, when the pressing stops, the bracket body 2031 can be driven to rebound by the elastic arms 2032, so that the circuit board 202 rebounds. Since multiple elastic arms 2032 are provided, pressing at any position can cause the elastic arms 2032 to be elastically deformed, which can improve the user experience.

[0045] In one possible implementation, Figure 3 As shown, the second ends of the multiple elastic arms 2032 include bolt holes 2033, the second ends of the multiple elastic arms 2032 are fixed to the housing 301 of the electronic device by bolts, and a silicone gasket 205 is included between the elastic arms 2032 and the housing 301 of the electronic device.

[0046] Figure 4 is a schematic diagram of a silicone gasket provided in an embodiment of the present application, such as Figure 4 As shown, the silicone gasket 205 is a ring-shaped silicone gasket 205. On the outer side, the upper and lower side edges of the silicone gasket 205 exceed the middle of the silicone gasket 205 to form an I-shaped silicone gasket 205 structure, such as Figure 2 As shown, the silicone gasket 205 can be sleeved on the bolt hole 2033 of the elastic arm 2032. When the second end of the elastic arm 2032 is fixed to the housing 301 of the electronic device by bolts, the silicone gasket 205 is included between the elastic arm 2032 and the electronic device housing 301, and between the elastic arm 2032 and the bolt.

[0047] In one example, Figure 5 is a schematic diagram of another pressure detection device provided in an embodiment of the present application, such as Figure 5 As shown, the elastic arm 2032 is fixed to the reinforcing plate 303 of the housing 301 of the electronic device by bolts. At this time, the silicone pad can be sleeved on the reinforcing plate 303, so that the silicone gasket 205 is included between the reinforcing plate 303 and the bolts, and between the reinforcing plate 303 and the elastic arm 2032.

[0048] In an embodiment of the present application, the second ends of the multiple elastic arms 2032 include bolt holes 2033, and the second ends of the multiple elastic arms 2032 are fixed to the housing 301 of the electronic device by bolts, thereby fixing the elastic arms 2032 to the housing 301 of the electronic device. Therefore, when the press detection device receives a press operation, the circuit board drives the bracket body to move, and the bracket body and the elastic arm 2032 produce relative movement, causing the elastic arm 2032 to undergo elastic deformation. Since a silicone gasket 205 is included between the bolt and the elastic arm 2032 and the housing 301 of the electronic device, the elastic arm 2032 can be prevented from being damaged due to structural component tolerances and structural stress, thereby improving the reliability of the press detection device.

[0049] In one possible implementation, Figure 3 As shown, the elastic arm 2032 includes a deformation portion 20321 parallel to the bracket body 2031, and a bending portion 20322 connecting the deformation portion 20321 and the bracket body 2031, and the angle between the bending portion 20322 and the bracket body 2031 is greater than zero degree.

[0050] against Figure 2 and Figure 3 In the structure of the elastic arm 2032 and the bracket body 2031 shown in the figure, the elastic arm 2032 can be bent downward, and the elastic arm 2032 includes a deformation portion 20321 and a bending portion 20322. The deformation portion 20321 and the bending portion 20322 of the elastic arm 2032 are an integrated structure, and the elastic arm 2032 and the bracket body 2031 are an integrated structure. In one example, the elastic arm 2032 can be obtained by stamping the bracket body 2031 and then bending it.

[0051] It should be noted that when the angle between the bending portion 20322 and the bracket body 2031 is equal to 0 degrees, the elastic arm 2032 and the bracket body 2031 are in the same plane, and there is a gap between the bracket body 2031 and the circuit board 202 and it cannot be bonded to the circuit board 202. Moreover, since the elastic arm 2032 and the bracket body 2031 are in the same plane, the elastic arm 2032 needs to be pressed by the user with greater force when it is deformed, and the strength requirement for the connection between the elastic arm 2032 and the electronic device housing 301 is relatively high. Therefore, the angle between the bending portion 20322 and the bracket body 2031 needs to be greater than 0 degrees. Preferably, the angle between the bending portion 20322 and the bracket body 2031 is 90 degrees.

[0052] In the embodiment of the present application, the elastic arm 2032 includes a deformation portion 20321 parallel to the bracket body 2031, and a bending portion 20322 connecting the deformation portion 20321 and the bracket body 2031, so that when the press detection device 200 is pressed, the bracket body 2031 drives the deformation portion 20321 to elastically deform through the bending portion 20322. Since the elastic arm 2032 is provided with the deformation portion 20321 and the bending portion 20322, compared with the bracket 203 structure scheme including only the deformation portion 20321, the force required for the user to press the press detection device 200 to deform the deformation portion 20321 is smaller, thereby improving the user's experience.

[0053] In a possible implementation, the sensor 104 includes a strain gauge, which is disposed on the deformation portion 20321 . The strain gauge is electrically connected to the circuit board 202 . The strain gauge can generate elastic deformation when the deformation portion 20321 generates elastic deformation to generate a pressing signal.

[0054] like Figure 2 As shown, the sensor 104 includes a strain gauge, which is arranged on the deformation part 20321. When the pressure detection device 200 receives a pressing operation, the circuit board 202 drives the bracket body 2031 and the elastic arm 2032 abutting against the circuit board 202 to produce relative movement, and the deformation part 20321 of the elastic arm 2032 produces elastic deformation. At this time, the strain gauge arranged on the deformation part 20321 produces elastic deformation together with the deformation part 20321 to generate a pressing signal. It should be noted that the strain gauge is arranged on the deformation part 20321, which can be as shown in FIG. Figure 2 The setting position in , or as Figure 2 The dotted line position in the figure is used for setting, and the specific setting position of the strain gauge is not limited here.

[0055] Optionally, when the press detection device 200 receives a press operation, the elastic arm 2032 generates elastic deformation, causing the strain gauge set on the elastic arm 2032 to generate elastic deformation, thereby generating a press signal. When the deformation amount of the elastic deformation generated by the strain gauge is different, the signal strength of the generated press signal is different (for example: when the press signal is a current signal, the change amount of the current is different; when the press signal is a voltage signal, the change amount of the voltage is different). When the press intensity of the press operation is large, the elastic deformation amount generated by the strain gauge is large. Therefore, the elastic deformation amount generated by the strain gauge can be determined based on the signal strength of the press signal, thereby determining the press intensity of the press operation received by the press detection device 200. For example: when the signal strength of the press signal is large, the press intensity is large; when the signal strength of the press signal is small, the press intensity is small. In this way, pressure detection can be performed on the press operation to determine the pressure size of the press operation.

[0056] In the embodiment of the present application, the sensor 104 includes a strain gauge, which is arranged on the deformation portion 20321. Therefore, when the elastic arm 2032 generates elastic deformation, a pressing signal can be generated by the strain gauge, thereby realizing the detection of the pressing operation.

[0057] In one possible implementation, Figure 2 As shown, the strain gauge is electrically connected to the circuit board 202 via the flexible circuit board 206 .

[0058] In the embodiment of the present application, the strain gauge is electrically connected to the circuit board 202 via the flexible circuit board 206, and the generated pressure signal can be transmitted to the circuit board 202. Since the strain gauge is arranged on the elastic arm 2032, and the elastic arm 2032 produces elastic deformation, the electrical connection through the flexible circuit board 206 can prevent the electrical connection line from being damaged due to deformation, thereby improving the reliability of the press detection device 200.

[0059] In a possible implementation, different strain gauges are respectively disposed on the multiple elastic arms 2032 .

[0060] In the embodiment of the present application, different strain gauges are arranged on the multiple elastic arms 2032, so that when pressing at any position of the press detection device 200, elastic deformation of any elastic arm 2032 can cause the strain gauge to generate a pressing signal. Therefore, compared with the touch pad with a half-domain pressing form in the prior art, the user can press anywhere without pressing at a specific position, thereby improving the user experience.

[0061] In one possible implementation, Figure 2 As shown, the press detection device further includes a cover plate 201, and a circuit board 202 is disposed between the cover plate 201 and a bracket 203. The cover plate 201 is used to provide a pressing surface. When the cover plate 201 is pressed, the press detection device 200 receives a pressing operation.

[0062] The cover plate 201 can provide a pressing surface. In one example, the cover plate 201 can be a glass cover plate 201. The circuit board 202 is arranged between the bracket 203 and the cover plate 201. When the pressing surface provided by the cover plate 201 is pressed, for example, by a finger, the cover plate 201 drives the circuit board 202 to move in the pressing direction, so that the circuit board 202 drives the bracket body 2031 to move in the pressing direction, and the elastic arm 2032 generates elastic deformation, so that the sensor 204 (for example, a strain gauge) generates a pressing signal to realize pressing detection. In one example, the cover plate 201 can be bonded to the circuit board 202 through the first adhesive layer 401.

[0063] Optionally, the circuit board 202 can be a circuit board 202 with a touch recognition function. In this case, the cover 201 can also provide a touch surface. When a finger slides on the cover 201, the circuit board 202 performs touch recognition on the finger sliding trajectory and generates a touch recognition signal. The circuit board 202 can transmit the touch recognition signal to the touch recognition chip on the circuit board 202 or the processing unit of the electronic device, so that the electronic device performs related operations corresponding to the finger sliding, such as: moving the cursor, moving the page, zooming the page, etc., which will not be repeated here.

[0064] In one example, Figure 6 is a structural explosion diagram of a pressure detection device provided in an embodiment of the present application, such as Figure 6 As shown, one side of the circuit board 202 can be bonded to the cover plate 201 through the first adhesive layer 401, and the other side of the circuit board 202 can be bonded to the bracket body 2031 through the second adhesive layer 402. The first adhesive layer 401 and the second adhesive layer 402 can be double-sided adhesive, optical adhesive (Optically Clear Adhesive, OCA) or other thermosetting adhesive films. Eight elastic arms 2032 are arranged on the bracket body 2031, and the elastic arms 2032 are connected to the housing 301 of the electronic device through bolts, and a silicone gasket 205 is included between the elastic arms 2032 and the housing 301 of the electronic device.

[0065] In an embodiment of the present application, the press detection device also includes a cover plate 201, thereby providing a pressing surface to the user. When the user presses the cover plate 201, the press detection device 200 can receive the pressing operation, so that the press detection device 200 can identify the user's pressing operation. Since the pressing position is not limited, a press signal can be generated when the cover plate 201 is pressed. Therefore, compared with the press detection scheme in the prior art, the user can press anywhere on the cover plate 201 without pressing at a specific position, thereby improving the user experience.

[0066] An embodiment of the present application further provides an electronic device, which includes a housing 301 and a pressure detection device 200 as in any of the above embodiments, wherein the bracket 203 in the pressure detection device 200 is fixed on the housing 301 .

[0067] In one example, the bracket 203 may be snap-connected to the housing 301 of the electronic device. In another example, the bracket 203 may be fixed to the housing 301 of the electronic device by screws, which is not limited herein.

[0068] In a possible implementation, the electronic device includes a laptop computer, and the bracket 203 in the pressure detection device 200 is fixed to a C-shell of the laptop computer, or fixed to a C-shell reinforcement plate 303 of the laptop computer.

[0069] Figure 7 is a cross-sectional view of an electronic device provided in an embodiment of the present application, such as Figure 7 As shown, Figure 7 (a) shows a solution of fixing the bracket 203 in the pressure detection device 200 to the C shell of the notebook computer. Figure 7 (b) shows a solution of fixing the bracket 203 in the pressure detection device 200 on the reinforcing plate 303 of the C-shell of the notebook computer.

[0070] In an embodiment of the present application, the bracket 203 in the press detection device 200 can be fixed to the C-shell of the laptop computer, or fixed to the reinforcement plate 303 of the C-shell of the laptop computer, so that the bracket 203 can be fixed to the outer shell of the electronic device. When the press detection device 200 receives a press operation, the elastic arm 2032 on the bracket 203 can be deformed so that the sensor 204 generates a press signal, thereby realizing the detection of the press operation.

[0071] In one possible implementation, Figure 7 As shown, the bracket 203 includes multiple elastic arms 2032 fixed to the C shell by bolts, or multiple elastic arms 2032 are fixed to the reinforcing plate 303 of the C shell by bolts, wherein a silicone gasket 205 is included between the elastic arms 2032 and the C shell or the reinforcing plate 303 of the C shell.

[0072] In an embodiment of the present application, a plurality of elastic arms 2032 are fixed to the C-shell by screws, or a plurality of elastic arms 2032 are fixed to the reinforcement plate 303 of the C-shell by screws, and a silicone gasket 205 is included between the elastic arm 2032 and the C-shell or the reinforcement plate 303 of the C-shell. Since the silicone gasket 205 is provided, the tolerance of the structural parts can be absorbed by the silicone gasket 205, thereby reducing the structural stress, preventing the elastic arm 2032 from being damaged, and improving the reliability of the press detection device 200.
