Description

Technical Field

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

[0002] Touchpads use touch sensors to detect the position and movement of the user's fingers and control pointer movement on the display interface. Traditional touchpads detect user presses using physical buttons to perform functions such as confirmation or menu retrieval. However, user presses can only be performed on certain areas of the touchpad, not on any arbitrary area.

[0003] To address the limitation of traditional touchpads that can only be pressed in specific areas, a pressure touchpad has been developed. This pressure touchpad uses pressure detection instead of physical button detection to perform functions such as confirmation and menu access. When a user presses the pressure touchpad, an actuator within it provides vibration feedback, offering a convenient and comfortable user experience. However, this type of pressure touchpad is relatively thick. Summary of the Invention

[0051] 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.

[0052] 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.

[0053] In related technologies, pressure touchpads are composed of multiple stacked components. Due to limitations in the thickness of the components themselves and the assembly structure, the pressure touchpad is relatively thick. For example, the presence of the actuator contributes to the overall thickness of the pressure touchpad. When the pressure touchpad is mounted on the C-shell of an electronic device (such as the casing where the keyboard is mounted on a laptop), it may interfere with components such as the battery.

[0054] In view of this, the present application aims to provide a pressure touchpad, which, by placing the actuator outside the main structure of the pressure touchpad, helps to reduce the thickness of the pressure touchpad and thus reduce interference with the battery in the electronic device during installation.

[0055] 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.

[0056] Figure 1 An isometric view of a pressure touchpad provided in an embodiment of this application; Figure 2 A front view of a pressure touchpad provided in an embodiment of this application; Figure 3 An exploded view of a pressure touchpad provided in an embodiment of this application; Figure 4 A simplified diagram of the connection structure between the reinforcing plate and the supporting plate provided in an embodiment of this application.

[0057] Please refer to Figures 1-4 This embodiment provides a pressure touch panel 10, including a cover plate 100, a circuit board 200, a reinforcing plate 300, an actuator 400, a pressure sensor, and a pressure sensor bracket 500. The cover plate 100, the circuit board 200, the reinforcing plate 300, and the pressure sensor bracket 500 are stacked sequentially along a first direction Z, wherein the first direction Z is perpendicular to the cover plate.

[0058] The cover plate 100 can be a glass cover or a protective cover made of other materials. It primarily provides an input surface for the user's fingers to touch or press, while also protecting components such as the circuit board 200 beneath the cover plate 100. The user can input touch-related commands by touching or moving their fingers on the cover plate 100. The finger can also press the cover plate 100 to apply downward pressure to the pressure touchpad 10, inputting commands related to pressing operations.

[0059] The cover plate 100 and the circuit board 200 can be bonded together by a first adhesive layer 700; the first adhesive layer 700 can be, for example, a double-sided adhesive layer or a thermosetting adhesive layer. A touch electrode layer is provided on the side of the circuit board 200 facing the cover plate 100. This touch electrode layer is mainly used to detect the touch position of the finger on the cover plate 100 and its movement on the cover plate 100, and output the position coordinate information of the finger touch or the dynamic vector information generated by the finger movement.

[0060] The circuit board 200 also houses electronic components and circuits. These electronic components include, for example, a touch controller, which can be mounted on the side of the circuit board 200 facing the reinforcing plate 300. The touch controller is electrically connected to the touch electrode layer and the pressure sensor via circuitry on the circuit board 200. The touch controller serves two purposes: firstly, it provides a drive signal to the touch electrode layer to drive touch detection; secondly, it receives touch sensing signals and pressure sensing signals output by the touch electrode layer and the pressure sensor when a finger presses the pressure touchpad 10, and determines the finger's position and the magnitude of the pressure applied based on these signals. The touch controller can also be connected to an actuator 400 and drives the actuator 400 to vibrate according to the pressure sensing signal output by the pressure sensor. The actuator 400 can vibrate the entire pressure touchpad 10 to provide pressure feedback to the user. In this embodiment, the actuator 400 can be, for example, a linear motor.

[0061] The circuit board 200 and the reinforcing plate 300 are bonded together by a second adhesive layer 800; the second adhesive layer 800 may be, for example, a double-sided adhesive layer or a thermosetting adhesive layer. The reinforcing plate 300 may be a metal plate (e.g., a stainless steel plate), which supports and protects the circuit board 200. The actuator 400 is fixedly connected to the reinforcing plate 300. When the actuator 400 vibrates, it causes the reinforcing plate 300 to vibrate, thereby causing the entire pressure touch panel 10 to vibrate.

[0062] The pressure sensor bracket 500 can be a metal bracket (e.g., a stainless steel bracket) used to provide support for the pressure sensor and other components in the pressure touchpad 10; the pressure sensor bracket 500 is also used to mount the pressure touchpad 10 onto the C-shell of the electronic device.

[0063] In this embodiment, the pressure sensor can be a piezoresistive sensor, which is disposed between the reinforcing plate 300 and the pressure sensor bracket 500. In one possible implementation, the pressure sensor is, for example, a strain gauge. A cantilever beam 510 is provided on the pressure sensor bracket 500, and the strain gauge is disposed on the side of the cantilever beam 510 facing the reinforcing plate 300. The cantilever beam 510 is bonded to the reinforcing plate 300 by an elastic gasket 520. The pressure applied when a finger presses the pressure touch panel 10 can cause the cantilever beam 510 to deform, thereby causing the strain gauge disposed on the cantilever beam 510 to deform synchronously, resulting in a change in resistance value. The touch controller can calculate the magnitude of the pressure based on the change in resistance value and further control the actuator 400 to vibrate to an appropriate degree.

[0064] Specifically, such as Figures 1-3 As shown, in this embodiment, the circuit board 200 facing the reinforcing plate 300 has a pressure sensor interface 210 and an actuator interface 220; the second adhesive layer 800 has a first through hole 801 corresponding to the pressure sensor interface 210 and a second through hole 802 corresponding to the actuator interface 220; the reinforcing plate 300 has a third through hole 301 corresponding to the first through hole 801. The pressure sensor is connected to one end of the first flexible flat cable 530, and the other end of the first flexible flat cable 530 passes through the third through hole 301 and the first through hole 801 in sequence and then connects to the pressure sensor interface 210, thereby realizing communication between the pressure sensor and the circuit board 200; the actuator 400 is connected to one end of the second flexible flat cable, and the other end of the second flexible flat cable passes through the second through hole 802 and then connects to the actuator interface 220, thereby realizing communication between the actuator 400 and the circuit board 200.

[0065] Optionally, in this embodiment, the first flexible flat cable 530 can be configured to include multiple bent and folded sections. This allows the first flexible flat cable 530 to have a certain degree of flexibility, thereby improving the fault tolerance when connecting the pressure sensor to the pressure sensor interface 210. For example, when there is a certain offset between the installation position of the pressure sensor and the preset position, the pressure sensor can be smoothly connected to the pressure sensor interface 210 by pulling the first flexible flat cable 530.

[0066] In this embodiment, the circuit board 200 has two pressure sensor interfaces 210 and one actuator interface 220. The pressure sensor interfaces 210 are generally located in the middle of the circuit board 200 in the second direction X; in the third direction Y, the two pressure sensor interfaces 210 are respectively located near the two sides of the circuit board 200. The actuator interface 220 is generally located between the two pressure sensor interfaces 210 in the third direction Y, and is located near the side of the circuit board 200 in the second direction X. The second adhesive layer 800 has two first through holes 801 and one second through hole 802. In the first direction Z, the positions of the two first through holes 801 correspond one-to-one with the positions of the two pressure sensor interfaces 210, and the position of the second through hole 802 corresponds to the position of the actuator interface 220. The reinforcing plate 300 has two third through holes 301. In the first direction Z, the two third through holes 301 correspond one-to-one with the two pressure sensor interfaces 210.

[0067] In this embodiment, a portion of the circuit board 200 is exposed within the third through hole 301 on the reinforcing plate 300. An electrostatic conductive sheet 230 is also connected between the circuit board 200 and the reinforcing plate 300, with both ends of the electrostatic conductive sheet 230 bonded to the circuit board 200 and the reinforcing plate 300, respectively. The electrostatic conductive sheet 230 can guide static electricity on the circuit board 300 to the reinforcing plate 300, and then discharge it through the C-shell of the electronic device, thereby reducing the damage of static electricity to the circuit board 200.

[0068] The pressure sensor bracket 500 is generally cuboid in shape. It includes two first support plates 540 arranged opposite each other along a second direction X and two second support plates 550 arranged opposite each other along a third direction Y. The two first support plates 540 and the two second support plates 550 are connected end-to-end to form a pressure sensor bracket 500 with a hollow portion 502. A cantilever beam 510 is located on the side of the second support plate 550 facing the hollow portion 502.

[0069] In this embodiment, the pressure sensor bracket 500 is provided with four cantilever beams 510, and each second support plate 550 is provided with two cantilever beams 510, with the two cantilever beams 510 respectively located near the two ends of the second support plate 550 along the second direction X. It can be understood that each cantilever beam 510 is provided with a pressure sensor and an elastic pad 520. Two pressure sensors connected to the same second support plate 550 are connected to the same first flexible flat cable 530; that is, in the third direction Y, the pressure sensors on the two cantilever beams 510 located on the same side are respectively connected to the first end and the second end of the same first flexible flat cable 530. The first flexible flat cable 530 also has a third end in the middle of the second direction X, and the third end of the first flexible flat cable 530 is connected along the third direction Y to the pressure sensor interface 210 on the circuit board 200, thereby realizing communication with the circuit board 200.

[0070] Please continue to refer to Figures 2-6 In one possible implementation, the reinforcing plate 300 of this embodiment is further provided with a thinning portion 330 on the side facing the pressure sensor bracket 500. The thinning portion 330 is a thinner area on the reinforcing plate, and the thickness of the thinning portion 330 along the first direction Z is less than the maximum thickness of the reinforcing plate 300 along the first direction Z. The specific thickness of the thinning portion 330 can be set according to the rigidity and other adjusting components of the reinforcing plate 300. The thinning portion 330 is located near the edge of the reinforcing plate 300, and the pressure sensor bracket 500 is connected to the thinning portion 330.

[0071] With the above settings, in the first direction Z, a portion of the thickness of the pressure sensor bracket 500 can overlap with the thickness of the reinforcing plate 300, thereby reducing the overall thickness of the pressure sensor bracket 500 and the reinforcing plate 300, which also reduces the thickness of the pressure touch panel 10, thus allowing a larger volume battery to be accommodated in the electronic device.

[0072] Specifically, in this embodiment, the thinning portion 330 includes two first thinning portions 331 arranged opposite each other along the second direction X and two second thinning portions 332 arranged opposite each other along the third direction Y. The two first thinning portions 331 and the two second thinning portions 332 are connected end to end. The thinning portion 330 also includes a third thinning portion 333 connected to the first thinning portions 331 and the second thinning portions 332. Corresponding to the cantilever beam 510, this embodiment provides four third thinning portions 333. Each second thinning portion 332 is connected to two third thinning portions 333, and the two third thinning portions 333 are respectively arranged close to the two ends of the second thinning portion 332 along the second direction X.

[0073] Along the first direction Z, the positions of the two first support plates 540 correspond one-to-one with the positions of the two first thinning portions 331, and the positions of the two second support plates 550 correspond one-to-one with the positions of the two second thinning portions 332. The four cantilever beams 510 are respectively bonded to the four third thinning portions 333 by four elastic pads 520. That is to say, the pressure sensor bracket 500 is only bonded to the four third thinning portions 333 by four elastic pads 520. The four elastic pads 520 create a certain gap between the pressure sensor bracket 500 and the reinforcing plate 300, which can provide deformation space when the user presses the pressure touchpad 10 along the first direction Z.

[0074] In this embodiment, the actuator 400 can be directly connected to the reinforcing plate 300 (e.g., connected to the reinforcing plate 300 through the housing of the actuator 400), or indirectly connected to the reinforcing plate 300 through other components. In the plane perpendicular to the first direction Z, the actuator 400 is located outside the projection range of the cover plate 100; that is, if the reinforcing plate 300 and its components facing the cover plate 100 (including the cover plate 100, circuit board 200, and reinforcing plate 300, etc.) are regarded as the main structure of the pressure touch panel 10, the actuator 400 is located outside the main structure of the pressure touch panel 10. Therefore, the thickness of the actuator in the first direction Z will not affect the thickness of the pressure touch panel 10, which is beneficial to reduce the thickness of the pressure touch panel 10 in the first direction Z, so as to reduce the interference of the pressure touch panel 10 with the battery in the electronic device during installation.

[0075] In one possible implementation, the pressure touch panel 10 of this embodiment further includes a support plate 600, which is connected to the reinforcing plate 300, and the actuator 400 is mounted on the support plate 600.

[0076] Optionally, the actuator 400 can be connected to the receiving plate 600 by means of bonding or welding. The receiving plate 600 and the reinforcing plate 300 can be two independent parts, and the receiving plate 600 and the reinforcing plate 300 can be fixed by means of welding, bonding, threaded connection, etc. Alternatively, the receiving plate 600 can also be integrally formed with the reinforcing plate 300 to reduce the number of parts or assembly process of the overall pressure touch panel 10.

[0077] Furthermore, in this embodiment, the size of the actuator 400 is less than or equal to the size of the receiving plate 600. That is, in a plane perpendicular to the first direction Z, the projection range of the actuator 400 is within the projection range of the receiving plate 600. With the above arrangement, the receiving plate 600 can better support the actuator 400 and better transmit the vibration force from the actuator 400.

[0078] In this embodiment, by first fixing the actuator 400 to the support plate 600, and then fixing the support plate 600 to the reinforcing plate 300, the stability of the connection between the actuator 400 and the reinforcing plate 300 can be ensured, which helps to prevent the actuator 400 from falling off when it vibrates.

[0079] Furthermore, the reinforcing plate 300 in this embodiment is generally cuboid in shape. The reinforcing plate 300 includes two first side edges 310 arranged opposite each other along the second direction X and two second side edges 320 arranged opposite each other along the third direction Y. The length of the first side edge 310 in the third direction Y is greater than the length of the second side edge 320 in the second direction X. The receiving plate 600 is connected to one of the first side edges 310. The first direction Z, the second direction X and the third direction Y are perpendicular to each other.

[0080] Specifically, after the pressure touchpad 10 is mounted on the electronic device along the first direction Z, it is generally located above the battery. The battery extends inside the electronic device along the third direction Y, and the length of the battery in the third direction Y is greater than the length of the pressure touchpad 10 in the third direction Y. Therefore, by connecting the receiving plate 600 and the reinforcing plate 300 to a first side 310 in the second direction X, the actuator 400 mounted on the receiving plate 600 can avoid the mounting area of ​​the battery, thereby reducing the thickness of the pressure touchpad 10 located above the battery and preventing interference between the pressure touchpad 10 and the battery.

[0081] Optionally, in the third direction Y, the receiving plate 600 of this embodiment is connected to the middle of the first side 310. Using the above method, the vibration force transmitted from the actuator 400 mounted on the receiving plate 600 to the reinforcing plate 300 is more uniform, thereby improving the user experience.

[0082] Please continue to refer to Figures 1-4 In one possible implementation, the receiving plate 600 of this embodiment is abutted to the first side 310 at one end along the second direction X; the receiving plate 600 and the reinforcing plate 300 have the same thickness in the first direction Z. That is, the sides of the receiving plate 600 and the reinforcing plate 300 located on the same side in the first direction Z are both in the same plane parallel to the second direction X and the third direction Y.

[0083] Furthermore, in this embodiment, an angle is formed between the receiving plate 600 and the first side 310, and the angle range can be greater than 0° and less than 180°. By adopting the above method, the actuator 400 mounted on the receiving plate 600 can select a suitable position as needed to avoid interference between the actuator 400 and other components in the electronic device.

[0084] Furthermore, in this embodiment, the angle between the receiving plate 600 and the first side 310 is 90°. That is, in this embodiment, the receiving plate 600 is perpendicular to the first side 310. With the above arrangement, it can be ensured that the actuator 400 installed on the receiving plate 600 can better transmit vibration to the reinforcing plate 300, reducing vibration loss during transmission.

[0085] Figure 5 An isometric view of a pressure touchpad 10 provided in another embodiment of this application; Figure 6 A simplified diagram of the connection structure between the reinforcing plate and the supporting plate provided in another embodiment of this application.

[0086] Please refer to Figures 5-6 The structure of the pressure touch panel 10 in this embodiment is largely the same as that in the previous embodiment. The difference lies in that the receiving plate 600 in this embodiment includes a first part 610 and a second part 620 connected to each other. The first end of the first part 610 along the first direction Z is fixedly connected to the first side 310; the second end of the first part 610 along the first direction Z is disposed towards the pressure sensor bracket 500. The first end of the second part 620 along the second direction X is connected to the second end of the first part 610 along the first direction Z; the second end of the second part 620 along the second direction X is a free end and is located on the side away from the reinforcing plate 300, and the actuator 400 is mounted on the second part 620.

[0087] In this embodiment, the actuator 400 and the reinforcing plate 300 are offset by a certain position using the first part 610, thereby reducing the interference of the actuator 400 with the motherboard. It should be noted that the extension distance of the first part 610 along the first direction Z in this embodiment can be determined as needed; preferably, the extension distance of the first part 610 along the first direction Z is less than the distance between the reinforcing plate 300 and the pressure sensor bracket 500, so that after the actuator 400 is installed on the second part 620, the actuator 400 is also located between the reinforcing plate 300 and the pressure sensor bracket 500 in the first direction Z, so as to better reduce the thickness of the pressure touch panel 10.

[0088] In one implementation, the actuator 400 of this embodiment is installed on the side of the receiving plate 600 facing the pressure sensor bracket 500, and the pressure sensor bracket 500 is provided with a clearance portion 501 corresponding to the actuator 400; in a plane perpendicular to the first direction Z, the projection range of the actuator 400 is located within the projection range of the clearance portion 501.

[0089] Specifically, the clearance portion 501 is disposed on the pressure sensor bracket 500 on the first support plate 540 corresponding to the first side 310 of the mounting receiving plate 600. The specific shape of the clearance portion 501 can be set as needed, as long as it can accommodate the actuator 400 and the receiving plate 600. For example, in a plane parallel to the second direction X and the third direction Y, the clearance portion 501 can be a groove formed by a portion of the first support plate 540 recessed along the second direction X towards the hollow portion 502.

[0090] In this embodiment, by providing a clearance part 501, interference between the actuator 400 and the pressure sensor bracket 500 can be prevented when the pressure touch panel 10 is pressed.

[0091] Figure 7 A simplified structural diagram of an electronic device provided in an embodiment of this application. Please refer to... Figure 7 This embodiment also provides an electronic device, including a C-shell 20, on which a mounting port 21 is provided, and a pressure touch panel 10 as described above is provided inside the mounting port 21.

[0092] Specifically, the electronic devices in this embodiment may be, for example, terminal devices, mobile phones, tablet computers and their accessories, keyboards, laptops, desktop computers, gaming devices, in-vehicle electronic devices or wearable smart devices, and other portable or mobile computing devices, as well as electronic databases, automobiles, bank automated teller machines (ATMs), and other electronic devices.

[0093] The C-shell 20 of the electronic device includes a top surface and multiple outer surfaces perpendicular to the top surface. The top surface is perpendicular to the first direction Z, and the mounting port 21 is located on the top surface. The pressure touchpad 10 can be fixed in the mounting port 21 on the C-shell 20 by a pressure sensor bracket 500; for example, the pressure sensor bracket 500 can be fixed in the mounting port 21 on the C-shell 20 along the first direction Z using fasteners such as screws. The specific installation method of the pressure touchpad 10 can be reasonably arranged according to the internal space of the C-shell 20 of the electronic device. For example, when the electronic device is a laptop, the mounting port 21 is offset to one side of the top surface in the second direction X, that is, the mounting port 21 is set closer to the outer surface that is closer to the user. Since the distance between this outer surface and the mounting port 21 is small, the space inside the electronic device corresponding to this location is insufficient to install the actuator 400. Therefore, the actuator 400 can be set away from this outer surface.

[0094] Because the electronic device in this embodiment uses the pressure touch panel 10 described in the above embodiment, the thickness of the pressure touch panel 10 is relatively small. After the pressure touch panel 10 is installed on the C-shell 20, it is less likely to interfere with the battery of the electronic device, which is beneficial for the electronic device to use a large-capacity battery to improve the battery life of the electronic device.
