Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to a pressure touchpad and an electronic device. Background Technology

[0002] For pressure touchpads with haptic feedback, the haptic feedback component needs to be placed at the bottom center of the touchpad to ensure that any area of ​​the touchpad touched by a finger can feel the same vibration during actual use.

[0003] However, in actual stacked device designs, the area directly below the touchpad is usually occupied by components such as battery packs and motherboards. Battery cells bulge during charging and discharging, and there isn't much safety space in the stacked device layout. To prevent the metal components of the haptic feedback device from contacting the battery cells and causing punctures and safety accidents, the haptic feedback device is typically placed off-center.

[0004] When the haptic feedback components are biased, inconsistent vibrations occur. Therefore, how to balance the vibrations of the pressure touchpad to improve the user experience becomes a problem that needs to be solved. Summary of the Invention

[0005] In view of this, this application provides a touchpad and electronic device that can solve the problem of inconsistent vibration caused by the bias of haptic feedback components.

[0006] In a first aspect, a pressure touchpad is provided, characterized in that it includes a touch panel, a pressure sensor, a touch controller, a support plate, and a haptic feedback component; the pressure sensor is disposed below the touch panel and is used to deform when a finger presses the pressure touchpad, and output a corresponding pressure sensing signal; the support plate is disposed below the touch panel, and the support plate includes two flexible connecting arms and a fastening area, the fastening area having a nut fixing hole; the support plate is fixedly connected to the touch panel through the two flexible connecting arms, and fixedly connected to the housing of an electronic device through the nut fixing hole in the fastening area; the two flexible connecting arms are connected to the fastening area and... The two flexible connecting arms are located on both sides of the haptic feedback component. The haptic feedback component is installed below the touch panel. The distance from the installation position of the haptic feedback component to one long side of the pressure touch panel is greater than the distance from the installation position of the haptic feedback component to the other long side of the pressure touch panel. The haptic feedback component is used to provide vibration feedback in response to the pressure applied by the finger. The touch controller is mounted and fixed on the lower surface of the touch panel and electrically connected to the pressure sensor. It is used to determine the touch position of the finger on the pressure touch panel and to receive the pressure sensing signal from the pressure sensor to determine the pressure applied by the finger.

[0007] Therefore, this application provides a pressure touchpad that is integrated with the fastening area of ​​the support plate and two flexible connecting arms, which simplifies the assembly process of the touchpad. When the haptic feedback component vibrates, the relative displacement of the flexible connecting arms is used to transmit the vibration, which helps to distribute the vibration generated by the haptic feedback component evenly to various positions of the pressure touchpad. This helps to solve the problem of inconsistent vibration when the haptic feedback component is biased and improves the user's vibration experience.

[0008] In one possible implementation, the two flexible connecting arms are equidistant from the haptic feedback component, and the two flexible connecting arms extend along a second direction perpendicular to the vibration direction of the haptic feedback component; wherein, the second direction is the short side direction of the pressure touchpad.

[0009] Since the two flexible connecting arms are equidistant from the haptic feedback component, and the extension direction of the two flexible connecting arms is perpendicular to the vibration direction of the haptic feedback component, the vibration generated by the haptic feedback component is evenly distributed across the pressure touchpad, thereby solving the problem of inconsistent vibration when the haptic feedback component is biased and improving the user's vibration experience.

[0010] In one possible implementation, the two flexible connecting arms are respectively separated from the touch panel by gaps, and the two flexible connecting arms are used to balance the vibrations generated by the haptic feedback component.

[0011] A gap exists between the flexible connecting arms and the touch panel to provide space for the touch panel to deform under the pressure of a finger pressing. When the haptic feedback component vibrates, the two flexible connecting arms undergo micro-movements in a direction parallel to the vibration direction of the haptic feedback component, thereby balancing the vibration of the haptic feedback component.

[0012] In one possible implementation, the fastening area is located around the support plate, and the fastening area includes two long side areas and two short side areas. The two long side areas and the two short side areas of the fastening area enclose a window area, and the two flexible connecting arms are located within the window area.

[0013] The two long and two short sides of the fastening area enclose the window area, which reduces the weight of the support plate and makes the entire pressure touch panel lighter. The two flexible connecting arms are placed in the window area, which provides displacement space for the flexible connecting arms to balance the vibration generated by the haptic feedback components.

[0014] In one possible implementation, the two flexible connecting arms include a first flexible connecting arm and a second flexible connecting arm. Both the first flexible connecting arm and the second flexible connecting arm include a main body and a connecting part. One end of the main body is integrally connected to the fastening area, and the other end of the main body is connected to the connecting part. The connecting part is fixedly connected to the touch panel.

[0015] One end of the main body of the two flexible connecting arms is integrated with the fastening area, and the other end of the main body of the two flexible connecting arms is connected with the connecting part, which is fixedly connected to the touch panel. This simplifies the assembly process of the touch panel and enhances the stability of the flexible connecting arms.

[0016] In one possible implementation, the main body is elongated and extends along a second direction, the aspect ratio of the main body is greater than or equal to 10:1, and the width of the main body is greater than or equal to 1.5 mm.

[0017] By designing the main body of the two flexible connecting arms as elongated strips extending along the second direction, the vibration transmission is more uniform and the flexible connecting arm structure is more stable when balancing the vibration of the haptic feedback component. Furthermore, the aspect ratio of the main body is greater than or equal to 10:1, which effectively shortens the vibration tailing time (or braking time) of the haptic feedback component, resulting in a crisper vibration experience. The width of the main body is greater than or equal to 1.5mm, which enhances the connection strength between the two flexible connecting arms and the fastening area, making the connection less prone to breakage.

[0018] In one possible implementation, the connecting portion of the two flexible connecting arms is provided with a flexible connecting arm opening for placing a fastener, which securely connects the two flexible connecting arms to the touch panel.

[0019] The flexible connecting arm has a flexible connecting arm opening on its connecting part for fixed connection with the touch panel, which enhances the tightness between the support plate and the touch panel. One end of the flexible connecting arm body is connected to the connecting part and is fixedly connected to the touch panel by fasteners. The other end of the flexible connecting arm body is integrated with the fastening area, making the flexible connecting arm more stable.

[0020] In one possible implementation, the support plate also includes four pressure sensor support areas for supporting the pressure sensor and causing the pressure sensor to deform together when the pressure touch panel is subjected to pressure.

[0021] In this embodiment, the pressure sensor support area for supporting the pressure sensor and the fastening area for supporting the touch panel are integrally formed, eliminating the need for an additional elastic bracket for supporting the pressure sensor. This reduces the number of components on the touch panel, thereby simplifying the assembly process and saving costs.

[0022] In one possible implementation, the four pressure sensor support areas are symmetrically distributed at the four corners of the support plate; each of the four pressure sensor support areas has a connecting end and an extension end, the connecting end is integrally connected to the fastening area, the extension end is located in the window area, and the extension direction of the extension end forms an angle with the long side or the short side of the support plate.

[0023] In this embodiment, a pressure sensor support area is provided at each of the four corners of the support plate, which can increase the structural stability of the touch panel. Secondly, distributing the pressure sensors at the four corners of the support plate through the pressure sensor support areas can also improve the uniformity of pressure detection.

[0024] In one possible implementation, the four pressure sensor support areas are symmetrically distributed at the four corners of the support plate; each of the four pressure sensor support areas has a connecting end and an extension end, the two short side areas of the fastening area are provided with four openings, the connecting end is integrally connected to the short side area of ​​the fastening area, the extension end is located in the opening, and the extension direction of the extension end is parallel to the short side of the support plate.

[0025] In one possible implementation, both the first flexible connecting arm and the second flexible connecting arm are connected to the same long side region of the fastening area. The two flexible connecting arms are disposed between the two pressure sensor support areas on the same long side of the support plate and are respectively close to the two pressure sensor support areas on the same long side of the support plate. Alternatively, the first flexible connecting arm and the second flexible connecting arm are respectively connected to two different long side regions of the fastening area. The two flexible connecting arms are disposed between the two pressure sensor support areas on the diagonal of the support plate and are respectively close to the two pressure sensor support areas on the diagonal of the support plate.

[0026] The first flexible connecting arm and the second flexible connecting arm are respectively positioned close to two different pressure sensor support areas. There is a gap between the two flexible connecting arms and the pressure sensor support area, so that the displacement of the two flexible connecting arms and the deformation of the pressure sensor support area do not affect each other.

[0027] In one possible implementation, the pressure touchpad further includes a damping component disposed between the touch panel and the pressure sensor support area, for causing the pressure sensor support area to deform when the touch panel is subjected to pressure.

[0028] In this embodiment, by providing a damping component between the pressure sensor support area and the touch panel, the pressure sensor support area can be deformed, thereby causing the pressure sensor to deform and enabling the pressure sensor to detect pressure.

[0029] In one possible implementation, the touch panel includes: a printed circuit board, the upper surface of which is provided with a touch electrode layer, the touch electrode layer being used to sense the touch position of the finger when the finger touches or presses the pressure touch panel, and to output a corresponding touch sensing signal.

[0030] In one possible implementation, the touch panel further includes a reinforcing plate disposed between the printed circuit board and the support plate.

[0031] In this embodiment, by setting a reinforcing plate between the printed circuit board and the support plate, the rigidity of the entire touchpad can be increased, making its structure less prone to deformation when a finger presses the touchpad.

[0032] In one possible implementation, the reinforcing plate has through holes, through which fasteners pass to the flexible connecting arm openings and the through holes, fixing the two flexible connecting arms and the reinforcing plate to the underside of the printed circuit board.

[0033] Fasteners are used to securely connect the printed circuit board, reinforcing plate, and two flexible connecting arms, enhancing the tightness between the printed circuit board and the reinforcing plate, and also improving the stability of the flexible connecting arms.

[0034] In one possible implementation, the fastener is a bolt and a nut, the nut being disposed on the lower surface of the printed circuit board and the upper surface of the reinforcing plate, the bolt passing through the flexible connecting arm opening and the through hole, and the bolt being locked to the nut.

[0035] In this embodiment, a nut is placed on the lower surface of the printed circuit board and on the upper surface of the reinforcing plate. A bolt passes through the opening of the flexible connecting arm and the through hole of the reinforcing plate, fixing the reinforcing plate and the flexible connecting arm to the lower surface of the printed circuit board, thereby enhancing the stability between the printed circuit board, the reinforcing plate, and the flexible connecting arm.

[0036] In a second aspect, an electronic device is provided, including a housing and a pressure touchpad as described in the first aspect and any implementation thereof, the housing being used for fixed connection with the fastening area. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0047] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0048] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

[0049] A touchpad is an input device used in electronic devices to control the cursor on the screen. By detecting minute changes in capacitance when a user's finger operates on the panel area, the touchpad obtains high-resolution finger coordinates and other touch information to precisely control the movement and clicking of the screen cursor. Typically, a single button is also located on the back of the touchpad, and by detecting the button's behavior, it performs the functions of a traditional left and right mouse button.

[0050] To improve the ease of use of touchpads, pressure-sensitive touchpads are gradually becoming a new trend. Pressure-sensitive touchpads eliminate the physical buttons of conventional touchpads and add pressure sensing and vibration feedback functions.

[0051] Pressure touchpads in electronic devices typically consist of a touch panel, a pressure sensor, and haptic feedback components. The haptic feedback components must be positioned directly below and in the center of the touch panel to ensure that, during actual use, any area of ​​the touch panel touched by a finger experiences the same vibration.

[0052] However, in actual stacked design, the battery pack and motherboard are usually located directly below the pressure touchpad. The battery cells bulge during charging and discharging, and there isn't much safety space in the stacked design. To prevent the metal components of the haptic feedback device from contacting the battery cells and causing a puncture and safety accident, the haptic feedback device is usually placed off-center. For example, it can be placed between the plastic frame of the battery casing and the touchpad, or between the motherboard and the touchpad.

[0053] When the haptic feedback component is biased, inconsistent vibrations occur.

[0054] In view of this, the present application provides a pressure touchpad, which helps to solve the problem of inconsistent vibration after the haptic feedback component is biased.

[0055] It should be understood that the technical solutions of the embodiments of this application can be applied to various electronic devices.

[0056] Examples include portable or mobile computing devices such as smartphones, laptops, tablets, and gaming devices, as well as other electronic devices such as electronic databases, automobiles, and automated teller machines (ATMs). However, the embodiments in this application are not limited to these.

[0057] Figure 1 An exploded view of a pressure touchpad 100 according to an embodiment of this application is shown. This pressure touchpad 100 can be applied to electronic devices. Figure 1 As shown, the pressure touchpad includes: a touch panel 110, a pressure sensor 120, a touch controller 130, a support plate 140, and a haptic feedback component 150.

[0058] A pressure sensor 120 is disposed below the touch panel 110 and is used to deform when a finger presses the pressure touchpad 100, and output a corresponding pressure sensing signal; the pressure sensor 120 can be a piezoresistive pressure sensor, for example, a strain gauge pressure sensor. Figure 1 As shown, the pressure sensor 120 can be disposed between the support plate 140 and the touch panel 110.

[0059] A support plate 140 is disposed below the touch panel 110. The support plate 140 includes two flexible connecting arms 141 and a fastening area 142. The fastening area 142 is provided with nut fixing holes 146. The support plate 140 is fixedly connected to the touch panel 110 through the two flexible connecting arms 141 and fixedly connected to the housing of the electronic device through the nut fixing holes 146. The two flexible connecting arms 141 are connected to the fastening area 142 and are located on both sides of the haptic feedback component 150. The two flexible connecting arms 141 include a first flexible connecting arm 1411 and a second flexible connecting arm 1412. For example, in the first direction X, the first flexible connecting arm 1411 is located on the left side of the haptic feedback component 150, and the second flexible connecting arm 1412 is located on the right side of the haptic feedback component 150. The support plate 140 has a certain strength and is used not only to support the touch panel 110 but also to fix the pressure touchpad 100 to the electronic device.

[0060] A haptic feedback component 150 is mounted below the touch panel 110. The distance from the mounting position of the haptic feedback component 150 to one long side of the pressure touchpad 100 is greater than the distance from the mounting position of the haptic feedback component 150 to the other long side of the pressure touchpad 100. Specifically, the distances from the mounting position of the haptic feedback component 150 to the two short sides of the pressure touchpad 100 are approximately equal, allowing for a certain degree of error. The distances from the mounting position of the haptic feedback component 150 to the two long sides of the pressure touchpad 100 are not equal. The haptic feedback component 150 is electrically connected to the touch controller 130 and provides vibration feedback in response to the magnitude of pressure applied by the finger. In this embodiment, the haptic feedback component 150 provides vibration feedback to the user based on the pressure signal detected by the pressure sensor 120.

[0061] It should be noted that in this application, the first direction X is the long side direction of the pressure touchpad 100, and the second direction Y is the short side direction of the pressure touchpad 100.

[0062] The touch controller 130 is mounted and fixed on the lower surface of the touch panel 110 and electrically connected to the pressure sensor 120. It is used to determine the touch position of a finger on the pressure touchpad 100 and to receive pressure sensing signals from the pressure sensor 120 to determine the magnitude of pressure applied by the finger. The touch controller 130 can be electrically connected to the touch electrode layer and the pressure sensor 120. On one hand, it provides a drive signal to the touch electrode layer for capacitive touch detection; on the other hand, it receives the touch sensing signal output from the touch electrode layer and the pressure sensing signal output from the pressure sensor 120 when a finger presses the pressure touchpad 100, and determines the finger position information and the magnitude of pressure applied by the finger based on these signals. The touch controller 130 can also be connected to the haptic feedback component 150 to respond to the detected pressure and drive the haptic feedback component 150 to provide vibration feedback. In a specific embodiment, the touch controller 130 can be a touch chip integrating pressure detection and touch position detection, or it can include two separately configured pressure detection chips for detecting pressure and a touch chip for detecting touch position.

[0063] Therefore, the pressure touchpad in this embodiment of the application is integrated with the fastening area 142 of the support plate 140 and the two flexible connecting arms 141, which simplifies the assembly process of the pressure touchpad. When the haptic feedback component 150 vibrates, the vibration is transmitted through the relative displacement of the two flexible connecting arms 141, which helps to distribute the vibration generated by the haptic feedback component 150 evenly in various positions of the pressure touchpad. This solves the problem of inconsistent vibration when the haptic feedback component 150 is biased and improves the user's vibration experience.

[0064] like Figure 1-3 As shown, the two flexible connecting arms 141 of the support plate 140 are perpendicularly equidistant from the tactile feedback component 150. Specifically, the vertical distance from the first flexible connecting arm 1411 to the tactile feedback component 150 is approximately equal to the vertical distance from the second flexible connecting arm 1412 to the tactile feedback component 150; this approximation allows for a certain degree of error. The two flexible connecting arms 141 extend along the second direction Y, while the tactile feedback component 150 vibrates along the first direction X. In other words, the extension direction of the two flexible connecting arms 141 is perpendicular to the vibration direction of the tactile feedback component 150.

[0065] In this embodiment, the two flexible connecting arms 141 have both a constraint or vibration transmission relationship and can have a certain degree of relative displacement. That is, when the tactile feedback component 150 vibrates, the two flexible connecting arms 141 have micro-movements in a direction parallel to the vibration direction of the tactile feedback component 150, thereby balancing the vibration of the tactile feedback component 150.

[0066] The two flexible connecting arms 141 in the support plate 140 have gaps between them and the touch panel 110. These two flexible connecting arms 141 are used to balance the vibrations generated by the haptic feedback component 150. The gaps between the two flexible connecting arms 141 and the touch panel 110 provide deformation space for the touchpad to be pressed by a finger. When the haptic feedback component 150 vibrates, the two flexible connecting arms 141 exhibit micro-movements in a direction parallel to the vibration direction of the haptic feedback component 150, thereby balancing the vibration of the haptic feedback component 150.

[0067] Optionally, such as Figure 3 As shown, the support plate 140 includes two flexible connecting arms 141 and a fastening area 142. The support plate 140 is flexibly connected to the touch panel 110 through the two flexible connecting arms 141. One end of each of the two flexible connecting arms 141 is connected to the fastening area 142. The fastening area 142 can be used to support the touch panel 110 and can also be used to connect and fix the support plate 140 to the housing of the electronic device through the nut fixing holes 146 of the fastening area 142.

[0068] like Figure 3 As shown, the fastening area 142 is disposed around the support plate 140. The fastening area 142 includes two long side areas 1421 and two short side areas 1422. The two long side areas 1421 and the two short side areas 1422 of the fastening area 142 enclose the window area 143. Two flexible connecting arms 141 are disposed within the window area 143.

[0069] In this embodiment, a window area 143 is formed inside the fastening area 142 of the support plate 140, which reduces the weight of the support plate and makes the entire pressure touch panel lighter. The two flexible connecting arms are set in the window area, which can provide displacement space for the flexible connecting arms to balance the vibration generated by the tactile feedback component.

[0070] Optionally, the two flexible connecting arms 141 are disposed within the window area 143, and the two flexible connecting arms 141 are symmetrically distributed on both sides of the haptic feedback component 150 along the center line of the mounting position of the haptic feedback component 150 in the second direction Y. The extending direction of the two flexible connecting arms 141 is perpendicular to the vibration direction of the haptic feedback component 150. For example, as Figure 3As shown, two flexible connecting arms 141 are symmetrically arranged within the window area 143 along the centerline of the mounting position of the haptic feedback component 150 in the second direction Y, and the two flexible connecting arms 141 are connected to the fastening area of ​​the same long side of the support plate 140. When the haptic feedback component 150 vibrates in the first direction X, the two flexible connecting arms 141 extend in the second direction Y. The first flexible connecting arm 1411 and the second flexible connecting arm 1412 are symmetrical along the centerline of the support plate 140 in the second direction Y, that is, after the support plate 140 is symmetrical along the centerline of the support plate 140 in the second direction Y, the first flexible connecting arm 1411 and the second flexible connecting arm 1412 can completely overlap.

[0071] The haptic feedback component vibrates in the first direction X, providing a safe space for components other than the pressure touchpad and delivering a crisp, responsive vibration experience to the user. Since the two flexible connecting arms 141 are symmetrically distributed on both sides of the haptic feedback component 150 along its mounting position in the second direction Y, and their extension directions are perpendicular to the vibration direction of the haptic feedback component, the vibration generated by the haptic feedback component 150 can be evenly distributed across all positions of the pressure touchpad. This solves the problem of inconsistent vibration when the haptic feedback component is offset, improving the user's vibration experience.

[0072] Figure 4 for Figure 3 A schematic enlarged view of the first flexible connecting arm 1411 in the diagram.

[0073] Optionally, such as Figure 3 Combination Figure 4As shown, the two flexible connecting arms 141 include a first flexible connecting arm 1411 and a second flexible connecting arm 1412. The first flexible connecting arm 1411 includes a main body portion 14111 and a connecting portion 14112; the second flexible connecting arm 1412 includes a main body portion 14121 and a connecting portion 14112. That is, both flexible connecting arms 141 include a main body portion and a connecting portion. In the first flexible connecting arm 1411, the main body portion 14111 extends along the second direction Y, and its two ends are respectively connected to the long side region 1421 of the fastening area 142 and the connecting portion 14112, and the connecting portion 14112 is fixedly connected to the touch panel 110. In the second flexible connecting arm 1412, the main body portion 14121 extends along the second direction Y, and its two ends are respectively connected to the long side region 1421 of the fastening area 142 and the connecting portion 14112, and the connecting portion 14122 is fixedly connected to the touch panel 110. It should be understood that, in this application, the connecting portion 14112 of the first flexible connecting arm 1411 refers to the area where the first flexible connecting arm 1411 connects to the touch panel 110, and the connecting portion 14122 of the second flexible connecting arm 1412 refers to the area where the second flexible connecting arm 1412 connects to the touch panel 110. It should be noted that, as Figure 3 Combination Figure 4 As shown, the connection between the fastening area 142 and the two flexible connecting arms 141 forms a triangular region 1423 extending toward the window area 143. The triangular region 1423 is integratedly connected to the main body 14111 of the first flexible connecting arm 1411 and the main body 14121 of the second flexible connecting arm 1412.

[0074] This embodiment of the application integrates one end of the main body of the two flexible connecting arms with the fastening area, and the connecting part connected to the other end of the main body of the two flexible connecting arms is fixedly connected to the touch panel, which simplifies the assembly process of the touch panel and enhances the stability of the flexible connecting arms.

[0075] Optionally, in the embodiments of this application, the aspect ratio of the main body 14111 is greater than or equal to 10:1.

[0076] This application embodiment sets the aspect ratio of the two flexible connecting arm main bodies to be greater than or equal to 10:1, which can effectively shorten the vibration trailing time (or braking time) of the haptic feedback component, making the vibration experience crisper.

[0077] like Figure 4As shown, the length of the main body 14111 of the first flexible connecting arm 1411 is the length from arrow 1 to arrow 2, and the width of the main body 14111 is the length from arrow 3 to arrow 4. It should be noted that the structure and dimensions of the second flexible connecting arm 1412 can be referred to the description of the first flexible connecting arm 1411, and will not be repeated here for the sake of brevity.

[0078] Optionally, the main body of the two flexible connecting parts 141 is elongated and extends along the second direction Y. Specifically, the elongated shape is uniform in width and thickness, and the width of the main body is greater than or equal to 1.5 mm.

[0079] Furthermore, in order to ensure that the aspect ratio of the main body of the two flexible connecting arms is greater than or equal to 10:1, the length of the main body of the two flexible connecting arms can be greater than or equal to 15mm.

[0080] The main body of the two flexible connecting arms is set as a long strip, which is uniform in width and thickness. This allows the vibration transmission of the two flexible connecting arms to be more uniform and the structure of the flexible connecting arms to be more stable when balancing the vibration of the tactile feedback component. In addition, the width of the main body is greater than or equal to 1.5mm, which can enhance the connection strength between the two flexible connecting arms and the fastening area, making the connection less prone to breakage.

[0081] Optionally, such as Figure 2 As shown, the connecting portion 14112 of the first flexible connecting arm 1411 has a flexible connecting arm opening 14113, which is used to place a fastener 170. The fastener 170 fixes the first flexible connecting arm 1411 to the touch panel 110. Similarly, the connecting portion 14122 of the second flexible connecting arm 1412 has a flexible connecting arm opening 14123. The flexible connecting arm opening 14123 is used to place a fastener 170, which fixes the second flexible connecting arm 1412 to the touch panel 110.

[0082] By providing a flexible connecting arm opening on the connecting part of the flexible connecting arm, the fastener 170 passes through the flexible connecting arm opening for fixed connection with the touch panel, which enhances the tightness between the support plate and the touch panel. The connecting part connected to one end of the flexible connecting arm body is fixedly connected to the touch panel by the fastener, and the other end of the flexible connecting arm body is integrated with the fastening area. This arrangement makes the flexible connecting arm more stable.

[0083] Optionally, such as Figure 2 As shown, the support plate 140 is provided with a pressure sensor support area 144, which supports the pressure sensor 120 and causes the pressure sensor 120 to deform together when the pressure touch panel 100 is subjected to pressure. Figure 2As shown, the pressure sensor support area 144 is, for example, a cantilever beam structure.

[0084] Optionally, the pressure sensor support area 144 is used to support the pressure sensor 120, which can be understood as the pressure sensor 120 being fixed to the upper surface of the pressure sensor support area 144. It should be understood that the upper surface of the pressure sensor support area 144 here refers to the surface close to the touch panel 110, and the lower surface of the pressure sensor support area 144 refers to the surface away from the touch panel 110.

[0085] In this embodiment, the pressure sensor support area for supporting the pressure sensor is integrally formed with the fastening area for supporting the touch panel, eliminating the need for an additional elastic bracket for supporting the pressure sensor. This reduces the number of components on the touch panel, thereby simplifying the assembly process and saving costs.

[0086] Optionally, such as Figure 3 As shown, the support plate 140 is provided with four pressure sensor support areas, including a first pressure sensor support area 1441, a second pressure sensor support area 1442, a third pressure sensor support area 1443 and a fourth pressure sensor support area 1444. The four pressure sensor support areas are symmetrically distributed at the four corners of the support plate 140 in the first direction X or the second direction Y.

[0087] In this embodiment, a pressure sensor support area is provided at each of the four corners of the support plate, which can increase the structural stability of the touch panel. Secondly, distributing the pressure sensors at the four corners of the support plate through these pressure sensor support areas can also improve the uniformity of pressure detection.

[0088] Optionally, each of the four pressure sensor support areas 144 has a connecting end and an extension end. The connecting end is integrally connected to the fastening area 142, and the extension end is located within the window area 143. The extension direction of the extension end forms an angle with the long side or the short side of the support plate. For example, as... Figure 3As shown, the first pressure sensor support area 1441 includes a connecting end 14411 and an extension end 14412. The connecting end 14411 is integrally connected to the fastening area 142, and the extension end 14412 is suspended within the window area 143. The extension direction of the extension end 14412 forms an angle with the long side or the short side of the support plate. The second pressure sensor support area 1442 includes a connecting end 14421 and an extension end 14422. The connecting end 14421 is integrally connected to the fastening area 142, and the extension end 14422 is suspended within the window area 143. The extension direction of the extension end 14422 forms an angle with either the first direction X or the second direction Y. It should be noted that this angle is less than or equal to 90°, that is, the extension direction of the extension end can be between the first direction X and the second direction Y, or it can be either the first direction X or the second direction Y. It should be noted that the structures of the third pressure sensor support area 1443 and the fourth pressure sensor support area 1444 can be referred to the description of the first pressure sensor support area 1441 or the second pressure sensor support area 1442, and will not be repeated here for the sake of brevity. Optionally, the first flexible connecting arm 1411 and the second flexible connecting arm 1412 are both connected to the same long side area 1421 of the fastening area 142, and the two flexible connecting arms 141 are disposed between the two pressure sensor support areas on the same long side of the support plate 140 and are respectively close to the two pressure sensor support areas on the same long side of the support plate 140; or, the first flexible connecting arm 1411 and the second flexible connecting arm 1412 are respectively connected to two different long side areas 1421 of the fastening area 142, and the two flexible connecting arms 141 are disposed between the two pressure sensor support areas on the diagonal of the support plate 140 and are respectively close to the two pressure sensor support areas on the diagonal of the support plate 140. For example, two flexible connecting arms 141 are disposed between the first pressure sensor support area 1441 and the second pressure sensor support area 1442, with one end of the first flexible connecting arm 1411 connected to the fastening area 142 close to the first pressure sensor support area 1441, and one end of the second flexible connecting arm 1412 connected to the fastening area 142 close to the second pressure sensor support area 1442; or, two flexible connecting arms are disposed between the first pressure sensor support area 1441 and the third pressure sensor support area 1443, with one end of the first flexible connecting arm 1411 connected to the fastening area 142 close to the first pressure sensor support area 1441, and one end of the second flexible connecting arm 1412 connected to the fastening area 142 close to the third pressure sensor support area 1443.

[0089] Optionally, the first flexible connecting arm 1411 and the second flexible connecting arm 1412 are respectively disposed close to two different pressure sensor support areas 144, and there is a gap between the two flexible connecting arms 141 and the pressure sensor support areas 144, so that the displacement of the two flexible connecting arms 141 and the deformation of the pressure sensor support areas 144 do not affect each other. For example, as Figure 3 Combination Figure 4 As shown, the first pressure sensor support area 1441 and the second pressure sensor support area 1442 are located on the same long side of the support plate 140. One end of the first flexible connecting arm 1411 connected to the fastening area 142 is located between the first pressure sensor support area 1441 and the second pressure sensor support area 1442 arranged along the first direction X, and is close to the first pressure sensor support area 1441. One end of the first flexible connecting arm 1411, the connecting end 14411 of the first pressure sensor support area 1441, and the fastening area 142 are integrally connected. The other end of the second flexible connecting arm 1412 connected to the fastening area 142 is also located between the first pressure sensor support area 1441 and the second pressure sensor support area 1442 arranged along the first direction X, and is close to the second pressure sensor support area 1442. One end of the second flexible connecting arm 1412, the connecting end 14421 of the second pressure sensor support area 1442, and the fastening area 142 are integrally connected. It should be noted that, in the first direction X, the distance from the main body 14111 of the first flexible connecting arm 1411 to the short side of the support plate 140 where the first pressure sensor support area 1441 and the fourth pressure sensor support area 1444 are located is less than the distance from the first flexible connecting arm 1411 to the mounting position of the haptic feedback component 150. Similarly, the distance from the main body 14121 of the second flexible connecting arm 1412 to the short side of the support plate 140 where the second pressure sensor support area 1442 and the third pressure sensor support area 1443 are located is also less than the distance from the first flexible connecting arm 1411 to the mounting position of the haptic feedback component 150.

[0090] Optionally, such as Figure 2 As shown, the pressure touch panel 100 further includes a damping component 160, which is disposed between the touch panel 110 and the pressure sensor support area 144, and is used to cause the pressure sensor support area 144 to deform when the touch panel 110 is subjected to pressure.

[0091] Specifically, the damping component 160 can be arranged side-by-side with the pressure sensor 120 on the upper surface of the pressure sensor support area 144, and the damping component 160 can fill the gap between the upper surface of the pressure sensor support area 144 and the lower surface of the printed circuit board 112. When a finger presses the pressure touchpad 100, the damping component 160 can cause the pressure sensor support area 144 to deform, thereby causing the pressure sensor 120 to deform.

[0092] In this embodiment, by providing a damping component between the pressure sensor support area and the touch panel, the pressure sensor support area can be deformed, thereby causing the pressure sensor to deform and enabling the pressure sensor to detect pressure.

[0093] Alternatively, the damping component 160 can be a silicone elastic element, such as a silicone pad.

[0094] The damping component 160 can not only be used to cause the pressure sensor support area 144 to deform, but also to absorb the residual vibration generated by the haptic feedback component 150, thereby isolating the vibration of the pressure touch panel 100 so that it does not affect areas other than the pressure touch panel 100.

[0095] Optionally, the hardness of the damping component 160 can be selected between Shore hardness 20A and 30A to ensure that the damping component has a certain rigidity and to avoid strain on the damping component itself when the pressure touch panel 100 is subjected to pressure, which would affect the accuracy of pressure detection.

[0096] Optionally, the thickness of the damping component 160 can be set between 0.5mm and 0.8mm. This avoids insufficient strain space in the pressure sensor support area 144 due to an excessively small thickness of the damping component 160, which would prevent the pressure sensor 120 supported by the pressure sensor support area 144 from effectively detecting pressure. It also avoids inconsistent vibration of the pressure touchpad due to an excessively large thickness of the damping component 160.

[0097] Optionally, such as Figure 2 As shown, the touch panel 110 includes a printed circuit board 112. The upper surface of the printed circuit board 112 is provided with a touch electrode layer (not shown in the figure). The touch electrode layer is used to sense the touch position of the finger when the finger touches or presses the pressure touch panel 100, and output the corresponding touch sensing signal.

[0098] In addition to carrying and supporting the touch electrode layer, the printed circuit board 112 can also carry electronic components of the pressure touchpad 100, such as the touch controller 130 and the haptic feedback component 150.

[0099] Optionally, see [link to relevant documentation] Figure 2 The touch panel may also include a reinforcing plate 113, which is disposed between the printed circuit board 112 and the support plate 140, and the reinforcing plate 113 and the support plate 140 are connected by a damping member 120.

[0100] Optionally, such as Figure 2 As shown, the reinforcing plate 113 and the printed circuit board 112 can be bonded and fixed together by the first adhesive 114, that is, the upper surface of the reinforcing plate 113 and the lower surface of the printed circuit board 112 are bonded and attached together.

[0101] In this embodiment, by providing a reinforcing plate between the printed circuit board and the support plate, the rigidity of the entire touchpad can be increased, making its structure less prone to deformation when a finger presses the touchpad. Optionally, the connecting portion 14112 of the first flexible connecting arm 1411 and the connecting portion 14122 of the second flexible arm 1412 are fixed to the lower surface of the reinforcing plate 113, the printed circuit board 112 is fixed to the upper surface of the reinforcing plate 113, the reinforcing plate 113 is provided with a clearance hole 1131, and the haptic feedback component 150 passes through the clearance hole 1131 and is disposed on the lower surface of the printed circuit board 112.

[0102] Optionally, such as Figure 2 As shown, the connecting portion 14112 of the first flexible connecting arm 1411 has a flexible connecting arm opening 14113, and the connecting portion 14122 of the second flexible connecting arm 1412 has a flexible connecting arm opening 14123. The reinforcing plate 113 has through holes 1132, including a first through hole 11321 and a second through hole 11322. A fastener 170 passes through the flexible connecting arm opening 14113 of the first flexible connecting arm 1411 and the first through hole 11321 of the reinforcing plate 113; similarly, the fastener 170 passes through the flexible connecting arm opening 14123 of the second flexible connecting arm 1412 and the second through hole 11322 of the reinforcing plate 113. The fastener 170 fixes the two flexible connecting arms 141 to the lower surface of the reinforcing plate 113 and fixes the printed circuit board 112 to the upper surface of the reinforcing plate 113. The fastener 170 can be, for example, a fastening bolt 171 and a fastening nut 172, such as Figure 2 As shown, the fastening nut 172 is attached to the lower surface of the printed circuit board 112, and the fastening bolt 171 passes through the flexible connecting arm opening 14113 of the first flexible connecting arm 1411 and the first through hole 11321 of the reinforcing plate 113. Similarly, the fastening bolt 171 passes through the flexible connecting arm opening 14123 of the second flexible connecting arm 1412 and the second through hole 11322 of the reinforcing plate 113. The fastening bolt 171 and the fastening nut 172 are locked and fixed, fixing the two flexible connecting arms 141 to the lower surface of the reinforcing plate 113 and fixing the printed circuit board 112 to the upper surface of the reinforcing plate 113.

[0103] Fasteners are used to securely connect the printed circuit board, reinforcing plate, and two flexible connecting arms, enhancing the tightness between the printed circuit board and the reinforcing plate, and also improving the stability of the flexible connecting arms.

[0104] like Figure 2As shown, the reinforcing plate 113 is provided with clearance holes 1131, including a haptic feedback component clearance hole 11311 and a component clearance hole 11312. The haptic feedback component clearance hole 11311 is used to avoid the haptic feedback component 150, and the component clearance hole 11312 is used to avoid components located on the lower surface of the printed circuit board 112, such as the touch controller 130. The haptic feedback component 150 passes through the haptic feedback component clearance hole 11311 and is disposed on the lower surface of the printed circuit board 112.

[0105] In this embodiment, the pressure sensor 120 is disposed on the upper surface of the pressure sensor support area 144, below the reinforcing plate 113. A damping component 160 is provided on the pressure sensor support area 144, and the gap between the pressure sensor support area 144 and the reinforcing plate 113 is the thickness of the damping component 160. The pressure sensor 120 is electrically connected to components on the lower surface of the printed circuit board 112, for example, by using a sensor lead-out ribbon cable. Figure 2 As shown, the first lead-out ribbon cable 1451 connects to the pressure sensors disposed on the first pressure sensor support area 1441 and the fourth pressure sensor support area 1444, and then makes an electrical connection with the components disposed on the lower surface of the printed circuit board 112 in the component clearance hole 11312. The second lead-out ribbon cable 1452 connects to the pressure sensors disposed on the second pressure sensor support area 1442 and the third pressure sensor support area 1443, and then makes an electrical connection with the components disposed on the lower surface of the printed circuit board 112 in the component clearance hole 11312. A portion of the first lead-out ribbon cable 1451 and the second lead-out ribbon cable 1452 located in the fastening area 142 can be fixed to the fastening area 142 by means of, for example, adhesive.

[0106] Optionally, such as Figure 2 As shown, the touch panel 110 also includes a protective panel 111, which is disposed above the printed circuit board 112 and is used for finger touch and pressing.

[0107] Optionally, the protective panel 111 can be glass. The protective panel 111 is used for user touch and pressing, and can also serve as an aesthetic decoration. See also... Figure 2 The protective panel 111 and the printed circuit board 112 can be bonded together by the second adhesive 115, that is, the lower surface of the protective panel 111 and the upper surface of the printed circuit board 112 are bonded together.

[0108] Optionally, the first adhesive 114 and the second adhesive 115 may have a dynamic shear force greater than or equal to 7 MPa / 300 mm. 2 The adhesive or adhesive film, that is, the adhesive can be applied within 300mm. 2 The region has a dynamic shear force greater than or equal to 7 MPa.

[0109] It should be noted that the touch panel 110 may include a protective panel 111, a printed circuit board 112, and a reinforcing plate 113, or it may only include the protective panel 111 and the printed circuit board 112. Specifically, when the thickness of the protective panel 111 is greater than or equal to 0.7 mm, the touch panel 110 only includes the protective panel 111 and the printed circuit board 112. When the touch panel 110 includes the protective panel 111, the printed circuit board 112, and the reinforcing plate 113, the gap between the two flexible connecting arms 141 and the touch panel 110 is the gap between the two flexible connecting arms 141 and the reinforcing plate 113. The two flexible connecting arms 141 are fixed to the lower surface of the reinforcing plate 113 by fasteners 170, and the printed circuit board 112 is fixed to the upper surface of the reinforcing plate 113 by fasteners 170. For example, the fasteners 170 include fastening bolts 171 and fastening nuts 172. The fastening nut 172 is fixed to the lower surface of the printed circuit board 112 and the upper surface of the reinforcing plate 113. The fastening bolt 171 passes through the flexible connecting arm opening 14113 of the first flexible connecting arm 1411 and the first through hole 11321 of the reinforcing plate 113. Similarly, the fastening bolt 171 passes through the flexible connecting arm opening 14123 of the second flexible connecting arm 1412 and the second through hole 11322 of the reinforcing plate 113. The fastening bolt 171 is locked and fixed with the fastening nut 172. When the touch panel 110 is touched... When only the protective panel 111 and the printed circuit board 112 are included, that is, the touch panel 110 does not include the reinforcing plate 113, the protective panel 111 should have a certain rigidity so that the entire pressure touch panel is not easily bent or deformed. The gap between the two flexible connecting arms 141 and the touch panel 110 is the gap between the two flexible connecting arms 141 and the printed circuit board 112. The two flexible connecting arms 141 are fixed to the bottom of the printed circuit board 112 by fasteners 170. For example, the fastening nut 172 is fixed to the lower surface of the printed circuit board 112 and the upper surface of the two flexible connecting arms 141. The fastening nut 172 can be fixed to the lower surface of the printed circuit board 112, for example, by surface mount technology (SMT). The fastening bolt 171 passes through the flexible connecting arm opening 14113 of the first flexible arm 1411 and the flexible connecting arm opening 14123 of the second flexible connecting arm 1412, and the fastening bolt 171 and the fastening nut 172 are locked and fixed.

[0110] Optionally, the haptic feedback component 150 is a linear motor, such as a linear motor that vibrates along the X-axis.

[0111] Figure 5 A schematic rear structural view of the pressure touchpad according to an embodiment of this application is shown. Figure 6 A schematic rear structural view of a pressure touchpad according to another embodiment of this application is shown. It should be understood that... Figure 5 and Figure 6 All are structural diagrams viewed from below.

[0112] Optionally, such as Figure 5 Combination Figure 2 As shown, two flexible connecting arms 141 span the component clearance holes 11312 provided on the reinforcing plate 113, and are fixed to the lower surface of the reinforcing plate 113 by fasteners 170. Fasteners 170 also connect to the printed circuit board 112, fixing the printed circuit board 112 to the upper surface of the reinforcing plate 113. The two ends of the lead-out cable 145 are respectively connected to two pressure sensor support areas 144 located on the same short side, and the protruding portion of the lead-out cable 145 is electrically connected to the printed circuit board 112. Figure 5 Combination Figure 2 As shown, the lead-out ribbon cable 145 includes a first lead-out ribbon cable 1451 and a second lead-out ribbon cable 1452. The two ends of the first lead-out ribbon cable 1451 are respectively connected to the pressure sensor 120 on the surface of the first pressure sensor support area 1441 and the pressure sensor 120 on the surface of the fourth pressure sensor support area 1444. The protruding portion of the first lead-out ribbon cable 1451 is connected to the pressure sensor connector 180 on the lower surface of the printed circuit board 112. The two ends of the second lead-out ribbon cable 1452 are respectively connected to the pressure sensor 120 on the surface of the second pressure sensor support area 1442 and the pressure sensor 120 on the surface of the fourth pressure sensor support area 1442. The protruding portion of the second lead-out ribbon cable 1452 is connected to the pressure sensor connector 180 on the lower surface of the printed circuit board 112. Figure 5 As shown, the haptic feedback component 150, the components on the surface of the printed circuit board 112, and the touch controller 130 all pass through the clearance hole 1131 and are located within the window area 143.

[0113] like Figure 6 As shown, Figure 6 and Figure 5 The difference is that the two flexible connecting arms 141 do not extend beyond the component clearance holes 11312 provided on the reinforcing plate 113. Fasteners 170 fix the two flexible connecting arms 141 to the lower surface of the reinforcing plate 113, and simultaneously connect the printed circuit board 112, fixing the printed circuit board 112 to the upper surface of the reinforcing plate 113. For example... Figure 6 As shown, the haptic feedback component 150, the components on the surface of the printed circuit board 112, and the touch controller 130 all pass through the clearance hole 1131 and are located within the window area 143.

[0114] This application also provides yet another embodiment of a pressure touchpad, which can be referred to... Figure 7 and Figure 8 As shown. Figure 7 An exploded view of the structure of a pressure touchpad according to another embodiment of this application is shown. Figure 8 A schematic structural diagram of a support plate according to yet another embodiment of this application is shown.

[0115] like Figure 7 As shown, the pressure touchpad 200 includes a touch panel 210, a pressure sensor 220, a touch controller 230, a support plate 240, and a haptic feedback component 250. The touch panel 210 includes a protective panel 211, a printed circuit board 212, and a reinforcing plate 213. The printed circuit board 212 and the reinforcing plate 213 are bonded together using a first adhesive 214, and the printed circuit board 212 and the protective panel 211 are bonded together using a second adhesive 215. Specifically, in the third direction Z, from top to bottom, the components are: protective panel 211, second adhesive 215, printed circuit board 212, first adhesive 214, reinforcing plate 213, and support plate 240.

[0116] It should be noted that in this embodiment, the first direction X is the direction of the long side of the pressure touch panel, the second direction Y is the direction of the short side of the pressure touch panel, and the third direction Z is the direction perpendicular to the touch panel.

[0117] A pressure sensor 220 is disposed between the support plate 240 and the printed circuit board 212, located on the upper surface of the support plate, i.e., the side closest to the printed circuit board. The pressure sensor deforms when a finger presses the pressure touchpad 200 and outputs a corresponding pressure sensing signal. A touch controller 230 is mounted and fixed on the lower surface of the printed circuit board 212 and electrically connected to the pressure sensor 220. It is used to determine the touch position of the finger on the pressure touchpad 200 and to receive the pressure sensing signal from the pressure sensor 220 to determine the magnitude of the pressure applied by the finger. The support plate 240 is disposed below the touch panel 210 and includes two flexible connecting arms 241 and a fastening area 242, such as... Figure 7 and Figure 8As shown, the two flexible connecting arms 241 are the first flexible connecting arm 2411 and the second flexible connecting arm 2412, respectively. The support plate 240 is fixed to the touch panel 210 via the two flexible connecting arms 241, and the fastening area 242 is used for fixed connection with the housing of the electronic device. The two flexible connecting arms 241 are connected to the fastening area 242, and the two flexible connecting arms 241 are located on both sides of the haptic feedback component 250. The vertical distances of the two flexible connecting arms 241 to the haptic feedback component 250 are equal, that is, the vertical distance of the first flexible connecting arm 2411 to the haptic feedback component 250 and the vertical distance of the second flexible connecting arm 2412 to the haptic feedback component 250 are approximately equal, and this approximation allows for a certain degree of error. A haptic feedback component 250 is mounted below the touch panel 210. The distance from the mounting position of the haptic feedback component 250 to the two short sides of the pressure touchpad 200 is equal, while the distance from the mounting position of the haptic feedback component 250 to the two long sides of the pressure touchpad 200 is unequal. The haptic feedback component 250 is electrically connected to the touch controller 230 to provide vibration feedback in response to the magnitude of pressure applied by the finger.

[0118] In addition to carrying and supporting the touch electrodes, the printed circuit board 212 can also carry electronic components of the pressure touchpad 200, such as a touch controller 230 and a haptic feedback component 250.

[0119] like Figure 7 and Figure 8As shown, a fastening area 242 is disposed around the support plate 240. The fastening area 242 includes two long side regions 2421 and two short side regions 2422, which together form a window area 243. Two flexible connecting arms 241 are disposed within the window area 243. The two flexible connecting arms 241 are symmetrically disposed within the window area 243, and both flexible connecting arms 241 are connected to the same long side region 2421 of the fastening area 242. The tactile feedback component 250 vibrates in the first direction X, and the two flexible connecting arms 241 extend in the second direction Y. One end of the two flexible connecting arms 241 is used to connect to the fastening area 242, and the other end is used to fix it to the printed circuit board 212. The support plate 240 is also provided with four pressure sensor support areas 244, including a first pressure sensor support area 2441, a second pressure sensor support area 2442, a third pressure sensor support area 2443, and a fourth pressure sensor support area 2444. The four pressure sensor support areas 244 are symmetrically distributed at the four corners of the support plate 240 in the first direction X and the second direction Y. Specifically, the first pressure sensor support area 2441 and the fourth pressure sensor support area 2444 are symmetrical along the center line of the support plate 240 in the first direction X; the second pressure sensor support area 2442 and the third pressure sensor support area 2443 are symmetrical along the center line of the support plate 240 in the first direction X; the first pressure sensor support area 2441 and the second pressure sensor support area 2442 are symmetrical along the center line of the support plate 240 in the second direction Y; and the third pressure sensor support area 2443 and the fourth pressure sensor support area 2444 are symmetrical along the center line of the support plate 240 in the second direction Y.

[0120] Optionally, such as Figure 8 As shown, each of the four pressure sensor support areas has a connecting end and an extension end. The connecting end is integrally connected to the fastening area 242. The two short side regions 2422 of the fastening area 242 have four openings, and the extension ends are located in the four openings respectively, with the extension direction of the extension ends parallel to the short side of the support plate 240. Specifically, as... Figure 8As shown, the fastening area 242 of the support plate 240 has multiple openings in its two short side regions 2422, including a first opening 24221, a second opening 24222, a third opening 24223, and a fourth opening 24224. These four openings are used to house four pressure sensor support areas 244. The connecting ends of the four pressure sensor support areas 244 are connected to the short side regions 2422 of the fastening area 242, and the extending ends extend into the first opening 24221, the second opening 24222, the third opening 24223, and the fourth opening 24224, respectively. The four pressure sensor support areas 244 extend toward the two long sides of the support plate 240 in the second direction Y. The pressure touchpad 200 also includes a damping component 260 disposed between the printed circuit board 212 and the support plate 240. The damping component 260 and the pressure sensor 220 are fixed side-by-side on the upper surface of the pressure sensor support area 240 in the second direction Y, and the damping component 260 can fill the gap between the upper surface of the pressure sensor support area 244 and the lower surface of the printed circuit board 212.
