[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0041] refer to Figure 1 This is a schematic diagram illustrating the explosion effect of a touch module, which includes:

[0042] Elastic component 1;

[0043] Touchpad 2;

[0044] The support plate 3 is stacked on top of the touchpad 2 and is used at least to support the touchpad 2 via the elastic component 1.

[0045] The elastic component 1 is located between the touchpad 2 and the support plate 3, and is used to separate the touchpad 2 and the support plate 3, so that any position on the first surface of the touchpad 2 is spaced from the support plate 3; the first surface faces the support plate 3.

[0046] Wherein, when the first region of the second surface of the touchpad 2 is subjected to pressure in the direction of the support plate 3, the interval between the second region of the first surface and the support plate 3 is the first interval; the second region is the region corresponding to the first region.

[0047] When the pressure in the first region disappears, the gap between the second region and the support plate is called the second gap. The second gap is larger than the first gap, and the first region is any region on the second surface; the first surface and the second surface are opposite.

[0048] The elastic component 1 may include any elastic component, which can be compressed, stretched, and can return to its original position after compression and stretching.

[0049] For example, the elastic component 1 may include springs and sheet springs, etc.

[0050] The size, shape, color, and elasticity of the elastic component 1 can be determined according to the usage requirements and are not limited here.

[0051] The number and position of the elastic component 1 are not limited. The number of elastic components 1 can be one or more, and the elastic component 1 can be located between the support plate 3 and the touch panel 2.

[0052] For example, a plurality of elastic components 1 are distributed in different areas between the support plate 3 and the touch panel 2, for separating the touch panel 2 and the support plate 3, so that any position on the first surface of the touch panel 2 is spaced apart from the support plate 3, which can also be referred to as a gap. For example, positions close to the corners, different elastic components are located at different positions. In this way, the touch panel 2 can be moved to the support plate 3 according to the pressing force after being stressed at each position.

[0053] The distribution position of the elastic component 1 is not limited, which can separate the support plate 3 and the touch panel 2, and any position on the first surface of the touch panel 2 is spaced apart from the support plate 3.

[0054] The touch panel 2 can also be referred to as a touchpad. The touch panel 2 has a touch function and can detect touch operation and pressing operation. The structure of the touch panel 2 is not limited and can realize these functions. The structures and principles of different touch panels can be different.

[0055] The touch detection structure based on the capacitive sensing technology or the resistance sensing technology, such as the touch panel 2, can be a capacitive touch panel or a resistance touch panel.

[0056] The pressing force detection structure based on the pressure sensing technology, such as a pressure sensor or an inductive device. The touch panel 2 has a pressure sensor, which can detect the pressure corresponding to the pressing operation. The inductive device can determine the corresponding pressing force according to the change of the inductance value after being stressed.

[0057] The size, shape, color and material of the touch panel 2 can be determined according to the use demand, which is not limited here.

[0058] The support plate 3 is used for supporting and fixing the touch panel 2. The support plate 3 can be connected with the mainboard or the middle frame of the electronic device and fixed on the mainboard or the middle frame of the electronic device.

[0059] The material, size and shape of the support plate 3 are not limited and can be determined according to the use demand. For example, the size of the support plate 3 matches the size of the touch panel 2, for example, the same. The shape of the support plate 3 is the same as or similar to the shape of the touch panel 2.

[0060] For example, the support plate 3 can be a flat plate.

[0061] The support plate 3 and the touch panel 2 are stacked and connected by the elastic component 1, at least for supporting the touch panel 2 by the elastic component 1.

[0062] The support plate 3 has a first surface and a second surface, and the first surface and the second surface are opposite. The first surface and the second surface are not in contact with each other. Figure 1The first surface faces the support plate 3, and the second surface faces away from the support plate 3.

[0063] The elastic assembly 1 is arranged to allow any position on the first surface to have a spacing with the support plate 3, so that when any first region on the second surface is pressed, the second region on the second surface corresponding to the first region moves towards the support plate 3.

[0064] The spacing between different positions on the first surface and the touchpad 2 can be the same or different. The spacing is greater than the first spacing, and can also be equal to the second spacing.

[0065] After any first region on the second surface is pressed towards the direction of the support plate 3, the spacing between the second region on the first surface and the support plate 3 is the first spacing, and the second region is the region corresponding to the first region. The first spacing is smaller than the second spacing.

[0066] After the first region on the second surface is pressed, the elastic assembly 1 is contracted, the touchpad 2 moves towards the support plate 3, and the spacing between the second region on the first surface corresponding to the first region and the support plate 3 is reduced, so that any position in the whole domain of the touchpad 2 can move towards the support plate after being pressed.

[0067] For example, the contracted elastic assembly 1 can be at least one elastic component closest to the second region, or at least one elastic component supporting the second region.

[0068] For example, the distance units of the second spacing and the first spacing can be centimeters, millimeters, microns, etc.

[0069] In the case where the pressing force applied on the first region disappears, the second region has a second spacing with the support plate 3, i.e. the spacing between the second region and the support plate 3 returns to the second spacing. The elastic assembly 1 can increase the spacing between the second region on the first surface of the touchpad 2 and the support plate 3 from the first spacing to the second spacing through its own elastic force.

[0070] For example, the pressing force can cause the elastic assembly 1 to deform, and the pressing force is greater than the elastic force of at least one elastic component closest to the second region.

[0071] In the case where the touchpad 2 is not pressed, or after the pressing force disappears, the elastic assembly 1 can separate the support plate 3 from the touchpad 2, and any position on the first surface of the support plate 3 has a second spacing with the touchpad 2. The second spacing between different positions on the first surface and the touchpad 2 can be the same or different.

[0072] The touchpad in this solution can detect touch operations applied to it. When a touch operation is detected, the touchpad is subjected to pressure. A support plate is stacked on top of the touchpad and connected to it via an elastic component. The elastic component separates the touchpad and the support plate, creating a second gap between any position on the first surface of the touchpad and the support plate. When a user's finger presses any first area on the second surface of the touchpad, the distance between the corresponding second area and the support plate is the first gap, which is smaller than the second gap. When the user's pressure disappears (i.e., when the user's finger no longer presses the first area), the gap between the second area and the support plate returns to the second gap. This solution allows any position on the touchpad to be pressed, enabling movement towards the support plate under pressure. This increases the area of ​​the touchpad that can move towards the support plate under pressure, allowing for pressing and movement across the entire touchpad, thus improving the user experience.

[0073] In one embodiment, the positional relationship between the elastic component and the first surface includes at least one of the following:

[0074] The elastic component is connected to the central region of the first surface;

[0075] The elastic component is connected to an edge region in the first surface; wherein, the edge region is the region close to the edge of the first surface, and the elastic component is distributed along the edge;

[0076] The elastic component is connected to the target area, which is located between the central area and the edge area.

[0077] refer to Figure 2 This is a schematic diagram showing the contact position between the first surface of a touchpad and an elastic component. The elastic component 1 can be connected to the central area of ​​the first surface, and the connection method can include abutment and fixed connection. When the touchpad 2 is not subjected to pressure, the elastic component 1 can separate the support plate 3 and the touchpad 2 through the central area 2a of the first surface, so that any position on the first surface of the touchpad 2 can have a gap with the support plate 3, and this gap is denoted as the second gap.

[0078] With this configuration, the elastic component 1 can also reduce the gap between the corresponding second area on the first surface and the support plate 3 to the first gap when any first area on the second surface is pressed, thereby enabling the area where the force point of the touchpad 2 is located to move toward the support plate 3 after any point in the entire area of ​​the touchpad 2 is pressed.

[0079] In one embodiment, the first and second surfaces of the touchpad 2 are polygons, including but not limited to rectangles, hexagons, triangles, and trapezoids.

[0080] Reference Figure 3 is a schematic view of the position where the first surface of another touchpad contacts the elastic assembly, i.e. the schematic view of the connection between the elastic assembly 1 and the edge region in the first surface. Figure 3 is a schematic view of the position where the first surface of the touchpad 2 contacts the elastic assembly 1 when the first surface and the second surface of the touchpad 2 are rectangular.

[0081] Figure 3 The dark long strip is the region where the elastic assembly 1 contacts the first surface of the touchpad 2.

[0082] The elastic assembly 1 can be distributed along the first edge 2b and the second edge 2c, so that the elastic assembly 1 is arranged near the first edge 2b and the second edge 2c, thereby separating any position on the first surface of the touchpad 2 from the support plate 3, having the second interval.

[0083] For example, a plurality of elastic assemblies 1 can be arranged along each edge, and the arrangement can be continuous or spaced.

[0084] Reference Figure 4 is a schematic view of the position where the first surface of another touchpad contacts the elastic assembly, i.e. another schematic view of the connection between the elastic assembly 1 and the edge region in the first surface. Figure 4 is a schematic view of the position where the first surface of the touchpad 2 contacts the elastic assembly 1 when the first surface and the second surface of the touchpad 2 are rectangular.

[0085] The elastic assembly 1 is connected to the region in the first surface near the first edge 2b and the second edge 2c, and to the region in the first surface near the third edge 2d and the fourth edge 2e. The third edge 2d is opposite to the fourth edge 2e, and the first edge 2b is adjacent to the third edge 2d.

[0086] The first edge 2b, the second edge 2c, the third edge 2d and the fourth edge 2e are the four edges of the rectangular touchpad 2, and arranging the elastic assembly 1 along each edge can support the touchpad 2, so that any position on the first surface of the touchpad 2 has the second interval from the support plate 3.

[0087] For example, a plurality of elastic assemblies 1 can be arranged along each edge, and the arrangement can be continuous or spaced.

[0088] Reference Figure 5Fig. 4 is a schematic diagram of the contact position between the first surface of another touchpad and the elastic component, i.e. another schematic diagram of the connection between the elastic component 1 and the edge region in the first surface. The elastic component 1 can be connected to the region where each corner of the first surface is located, Figure 5 The black region in the touchpad 2 is the region where the elastic component 1 contacts the first surface of the touchpad 2.

[0089] By supporting each corner of the touchpad 2, any position on the first surface of the touchpad 2 can also be separated from the support plate 3 by a second interval, so that any region of the touchpad 2 can move towards the support plate 3.

[0090] Reference Figure 1 The number of elastic components 1 is 4, which are located in the regions near the four corners of the support plate 3. In this way, the touchpad 2 and the support plate 3 can be separated by the elastic component 1, so that any position on the first surface of the touchpad 2 is separated from the support plate 3 by a second interval. When any first region of the touchpad 2 is pressed, the elastic component 1 closest to the second region deforms and is compressed, and the region of the touchpad 2 where the force point is located moves towards the support plate 3. It can be applied to any region of the second surface of the touchpad 2, so that the entire region of the touchpad 2 can move towards the support plate according to the pressing operation.

[0091] Reference Figure 6 Fig. 4 is a schematic diagram of the contact position between the first surface of another touchpad and the elastic component, i.e. another schematic diagram of the connection between the elastic component 1 and the edge region in the first surface. Figure 6 Fig. 4 is a schematic diagram of the contact position between the first surface of another touchpad and the elastic component, i.e. another schematic diagram of the connection between the elastic component 1 and the edge region in the first surface. Figure 6 The black region in the touchpad 2 is the region where the elastic component 1 contacts the first surface of the touchpad 2.

[0092] The elastic component 1 is connected to multiple different positions near the edge of the first surface of the touchpad 2, and multiple elastic components are distributed in a circular, elliptical or polygonal shape.

[0093] When the first surface and the second surface of the touchpad 2 are circular or elliptical, the distribution of the elastic component 1 can be any distribution that can separate any position on the first surface of the touchpad 2 from the support plate 3, including but not limited to: circular, elliptical or polygonal distribution. It can also be located in the central region of the touchpad 2.

[0094] For example, the elastic component can also be connected to any two regions of the central region, the edge region and the target region of the first surface at the same time, and can also be connected to three regions at the same time.

[0095] In one embodiment, the elastic component 1 is located between the touchpad 2 and the support plate 3;

[0096] The elastic component 1 is fixed to the support plate 3, and / or the elastic component 1 is fixed to the touch panel 2.

[0097] The elastic component 1 is located between the touchpad 2 and the support plate 3, representing one positional relationship between the elastic component 1, the touchpad 2, and the support plate 3. In this case, the elastic component 1 may include a spring, a sheet, and other elastic parts. After the touchpad 2 is subjected to the pressing force corresponding to the pressing operation, the pressing force can be transmitted to the elastic component 1, thereby compressing the elastic component 1 and causing the touchpad 2 to move towards the support plate 3.

[0098] The elastic component 1 can be fixed to the support plate 3, for example, one end can be fixed to the support plate 3 and the other end can abut against the touch panel 2. Alternatively, the elastic component 1 can be fixed to the touch panel 2, with one end fixed to the touch panel 2 and the other end abutting against the support plate 3. Or, one end of the elastic component 1 can be fixed to the touch panel 2 and the other end fixed to the support plate 3.

[0099] In one embodiment, the elastic component 1 includes opposite first and second ends, and the support plate 3 has a connecting portion. Figure 1 (Not shown in the image), the support plate 3 has openings or grooves, the connecting part is the inner wall of the openings or grooves, and the first end is connected to the connecting part. The elastic component 1 is part of the support plate 3, and the elastic component 1 is integrally formed with the support plate 3.

[0100] After the first end of the elastic component 1 is connected to the connecting part, at least in the state where the pressing pressure is removed, the second end of the elastic component 1 protrudes from the support plate 3 on the side of the support plate 3 facing the touch plate 2. This allows the elastic component 1 to be located between the touch plate 2 and the support plate 3, thereby separating the touch plate 2 and the support plate 3.

[0101] For example, the elastic component 1 is a spring sheet. After one end of the spring sheet is fixed to the support plate 3, the rest of the spring sheet is not connected to the support plate 3. Because the spring sheet is elastic, it will deform when the rest of the spring sheet is subjected to pressure.

[0102] This allows the touchpad 2 to transmit the pressure to the elastic component 1 after being pressed, causing the elastic component 1 to deform. This facilitates the movement of the touchpad 2 towards the support plate 3, achieving the effect that the touchpad 2 can move according to the press.

[0103] Since the connecting part is the inner wall of the hole or groove on the support plate 3, by connecting the first end of the elastic assembly 1 with the connecting part, it can be achieved that when the elastic assembly 1 is contracted, the second end of the elastic assembly 1 moves into the hole or groove, so that the deformation distance of the elastic assembly 1 can be increased, and further the moving distance of the touchpad 2 to the support plate 3 is increased, which helps to improve the pressing experience.

[0104] For example, referring to Figure 1 , the support plate 3 is a flat plate, and the elastic assembly 1 is a bent plate-shaped elastic piece.

[0105] For example, the hole can be a through hole or a blind hole. When the hole is a blind hole or the connecting part is the inner wall of the groove, under the condition of the pressing force, the elastic assembly 1 is deformed under the force, and the elastic assembly 1 moves in the blind hole or the groove, and the second end is located in the hole or the groove, or protrudes from the side of the support plate 3 facing the touchpad 2, but will not exceed the surface of the support plate 3 facing away from the touchpad 2. In this way, the space occupied by the elastic assembly 1 on the side of the support plate 3 facing away from the touchpad 2 can be reduced.

[0106] In one embodiment, referring to Figure 1 , the touch module further comprises:

[0107] The connecting piece 4 is located between the elastic assembly 1 and the touchpad 2, and is used to connect the elastic assembly 1 and the touchpad 2.

[0108] Wherein, in the state that the pressing force of the pressing operation disappears, there is a second interval between the support plate 3 and the touchpad 2.

[0109] The connecting piece 4 as a component for connecting the elastic assembly 1 and the touchpad 2, by adding the connecting piece 4 between the elastic assembly 1 and the touchpad 2, the second interval between the support plate 3 and the touchpad 2 can be increased in the state that the pressing operation disappears, so as to improve the pressing feeling.

[0110] For example, the connecting piece 4 can also be located between the elastic assembly 1 and the touchpad 2. In this way, the interval between the elastic assembly 1 and the touchpad 2 can be increased, and the connecting piece 4 can also play a role in connecting the elastic assembly 1 and the touchpad 2.

[0111] In one embodiment, the connecting piece 4 comprises:

[0112] The connecting piece has elasticity;

[0113] Or,

[0114] The connecting piece has adhesion and elasticity.

[0115] The connector 4 is an elastic connector that can dampen vibrations and reduce the vibrations transmitted to the touchpad 2, thereby reducing the impact of vibrations on the touchpad 2 and improving the user experience of the touchpad 2.

[0116] The connector 4 is an adhesive and elastic connector that can simultaneously connect the elastic component 1 and the touch panel 2, as well as provide shock absorption.

[0117] For example, the connector 4 has adhesive properties to the two connecting surfaces of the elastic component 1 and the touch panel 2, thereby facilitating the connection of the connector 4 to the elastic component 1 and the touch panel 2.

[0118] For example, the number of connectors 4 is not limited and can be the same as the number of elastic components 1, with one elastic component 1 connected to the touchpad 2 via a connector 4.

[0119] For example, connector 4 is a connector made of materials such as silicone or plastic.

[0120] The shape, size, and thickness of the connector 4 are not limited, and the shape includes, but is not limited to, cuboid, cylinder, triangular prism, and annular shape.

[0121] For example, refer to Figure 7 This is a cross-sectional schematic diagram of a touchpad, the touchpad 2 includes:

[0122] Substrate 201 has opposite third and fourth surfaces ( Figure 7 (not shown in the image); the third surface faces away from the support plate 3, and the fourth surface faces the support plate 3;

[0123] Touch detection layer 202 is located on the third surface;

[0124] Pressure detection layer 203 is located on the fourth surface.

[0125] The material, size, and shape of the substrate 201 are not limited, and the shape can be a straight plate.

[0126] The touch detection layer 202 and the pressure detection layer 203 are located on opposite sides of the substrate 201. The third and fourth surfaces are opposite to each other. The touch detection layer 202 is located on the third surface facing away from the support plate 3, which makes it convenient for users to use.

[0127] The internal structure of the touch detection layer 202 is not limited; any component with touch detection functionality is acceptable. Similarly, the internal structure of the pressure detection layer 203 is not limited; any component with pressure detection functionality is acceptable.

[0128] The touch panel 2 can be a printed circuit board (PCB) including a substrate 201, a touch detection layer 202, and a pressure detection layer 203. The touch detection layer 202 can include a touch detection component, and the pressure detection layer 203 can include a pressure detection component.

[0129] The structures of the touch detection component and the pressure detection component are not limited, and the corresponding detection functions are sufficient. The subsequent embodiments can be referred to for further description.

[0130] The touch detection layer 202 and the pressure detection layer 203 can be metal layers, for example, copper layers.

[0131] The touch panel 2 can further include a solder mask layer 204 and a ground shield layer 205. The solder mask layer 204 is located on an outer surface of the touch panel 2, and the ground shield layer 205 is located between the pressure detection layer 203 and the substrate 201.

[0132] The touch detection layer 202 can include two layers, and a protective layer 206 can be located between the two layers. The protective layer 206 can be an insulating protective layer, such as a polyimide (PI) protective layer.

[0133] The protective layer 206 can also be located between the pressure detection layer 203 and the ground shield layer 205.

[0134] The touch detection layer 202 and the pressure detection layer 203 can be connected to the ground shield layer 205 through a connecting line 207.

[0135] In an embodiment, the support plate 3 is a metal support plate, or the support plate 3 includes a metal layer overlapping the pressure detection layer 203.

[0136] The pressure detection layer 203 can include an inductance detection circuit including an inductance element. The inductance element can include an inductance coil A. The distance between the inductance element and the metal layer or the metal support plate is positively correlated with the pressing force of the pressing operation and the inductance value of the inductance element.

[0137] The metal has an influence on the inductance value of the inductance element. The change in the distance between the metal and the inductance element can cause a change in the inductance value of the inductance element. Thus, after the touch panel 2 moves towards the support plate 3 under force, the distance between the touch panel 2 and the support plate 3 changes, and the inductance value of the inductance element changes.

[0138] The distance between the inductance element and the metal layer or the metal support plate is correlated with the inductance value of the inductance element and is also related to the pressing force of the pressing operation. Therefore, the change in the inductance value can be used to determine the pressing force received by the touch panel 2.

[0139] Since the pressure detection layer 203 is located on the second surface, and the second surface is the surface facing the metal support plate 3, the distance between the pressure detection layer 203 and the metal support plate 3 or the metal layer is reduced, which facilitates the detection of the inductance.

[0140] For example, the size of the outer diameter of the coil is positively correlated with the inductive distance of the coil. The larger the outer diameter of the coil is, the farther the inductive distance of the coil is. The smaller the outer diameter of the coil is, the closer the inductive distance of the coil is.

[0141] Reference Figure 8 is a schematic diagram of a coil, Figure 8 shows two different shapes of coils, Figure 8 part (a) of is a circular coil, Figure 8 part (b) of is an elliptical coil, and the inductive element can be one of them, Figure 8 the arrowed line in the coil indicates the outer diameter of the coil.

[0142] For example, the outer diameter can include a maximum outer diameter and a minimum outer diameter, Figure 8 the arrowed line in the elliptical coil shown in part (b) indicates the minimum outer diameter of the coil.

[0143] For example, the shape of the coil can be circular, elliptical, or polygonal, etc.

[0144] For example, the coil can be formed on the touchpad 2 by etching.

[0145] Figure 7 The vertical white gap 208 shown in the pressure detection layer 203 is the inductive detection circuit arranged in the pressure detection layer 203, such as Figure 8 the coil shown, which is a cross-sectional view of the coil.

[0146] In one embodiment, the distance between the inductive element and the metal layer or the metal support plate is negatively correlated with the inductive sensitivity of the inductive element.

[0147] Reference Figure 9 is a schematic diagram of the relationship between the distance between the inductive element and the metal and the inductive sensitivity of the inductive element. Through Figure 9 the curve in can be obtained that the smaller the distance between the inductive element and the metal is, the better the inductive sensitivity is. The larger the distance between the inductive element and the metal is, the worse the inductive sensitivity is. Figure 9 The relative inductance represented by the longitudinal axis in can represent the inductive sensitivity.

[0148] When the support plate 3 is a metal support plate, the distance between the pressure detection layer 203 and the support plate 3 is less than a preset distance. When the support plate is a non-metal support plate, the support plate 3 has a metal layer, and the distance between the pressure detection layer 203 and the metal layer is less than a preset distance. The preset distance can be determined according to the use requirement, for example, a distance between 5 mm and 10 mm.

[0149] In one embodiment, referring to Figure 10 Fig. 1 is a schematic diagram of an inductance detection circuit. The inductance detection circuit can be connected to a voltage source, and the circuit includes an inductor L1 and a resistor R1 and a capacitor C1. The inductor L1 and the resistor R1 are connected in series, and the capacitor C1 is connected in parallel with the inductor L1 and the resistor R1. The resistor R1 is a known resistor, and the capacitor C1 is a known capacitor.

[0150] For example, the resistor R1 can be the combined resistance of one or more components between the inductor L1 and the ground.

[0151] Referring to Figure 11 Fig. 2 is a schematic diagram of another inductance detection circuit. The inductance detection circuit can be connected to a voltage source, and the circuit includes an inductor L2 and a resistor R2 and a capacitor C2.

[0153] In one embodiment, the touch module further includes:

[0154] A first controller 5 connected to the inductance detection circuit, for generating a vibration control signal according to the inductance detected by the inductance detection circuit;

[0157] The first controller 5 can be located on the touch plate 2, and the location in the touch plate 2 is not limited.

[0158] For Figure 5The inductance detection circuit is shown in the figure. The voltage source can provide voltage to the inductance detection circuit in the form of alternating current. The first controller 5 can measure the voltage at the joint between the inductor L1 and the resistor R1. When the distance between the inductor coil and the metal support plate 3 or the metal layer on the support plate 3 changes, the inductance also changes, resulting in a change in the equivalent resistance. The first controller 5 can determine the change in inductance according to the node voltage, thereby determining the pressing force. When the amount of inductance change exceeds the change threshold, the first controller 5 generates a vibration control signal, and the vibration assembly 6 generates vibration according to the vibration control signal.

[0159] For Figure 11 The inductance detection circuit is shown in the figure. The voltage source can provide voltage to the inductance detection circuit in the form of alternating current. The first controller 5 can measure the voltage across the inductor L1. When the distance between the inductor coil and the metal support plate 3 or the metal layer on the support plate 3 changes, the inductance also changes, resulting in a change in the equivalent resistance.

[0167] The second controller 8 can be any device with control function, such as a processor (Central Processing Unit, CPU) or a microcontroller unit (Microcontroller Unit, MCU).

[0168] Exemplarily, the second controller 8 can be the same as the first controller 5.

[0169] In an embodiment, the touch module further comprises:

[0170] A near field communication module is located on the touch plate 2 and is used for receiving and transmitting wireless communication signals. The near field communication module can include a Near Field Communication (NFC) module and can also include a module with other near field communication functions. Through the module, information interaction with other external devices can be achieved.

[0172] In an embodiment, referring to Figure 1 , the touch module further comprises:

[0173] A signal enhancement component 9 is located on the touch plate 2 at a position corresponding to the near field communication module and is used for enhancing the signal strength of the wireless communication signal.

[0174] Exemplarily, the support plate 3 also has a through hole 301, and the signal enhancement component 9 and the vibration component 6 are located in the through hole 301.

[0181] The adhesive layer 11 is arranged between the cover plate 10 and the touchpad 2, and is configured to connect the cover plate 10 and the touchpad 2.

[0182] The adhesive layer 11 can be a pressure-sensitive adhesive or a thermosetting adhesive, and can improve the firmness of the cover plate 10 and the touchpad 2.

[0183] Reference Figure 12 is a schematic view of an assembled touch module.

[0184] In one embodiment, an electronic device is also provided, comprising:

[0185] The touch module in any of the above embodiments.

[0186] In another embodiment, with the rapid development of the notebook computer industry, the large size and pressure recognition feedback of the touchpad are important development directions. Precise pressure recognition can bring better touchpad clicking experience to users. How to achieve high-precision feedback of the touchpad and thinning is a problem to be solved at present.

[0187] The touchpad has a hinged surface that pivots along one of its edges, and more than half of the area is designed to be suspended. A structure switch is arranged below the suspended area to allow a user to input a pressing click. Therefore, this touchpad has about half of the area that can be pressed and moved, becoming a half-area pressure touchpad.

[0188] This embodiment provides an example of a touch module.

[0189] As Figure 1 shown, the touch module comprises:

[0190] The support plate 3 can be a reinforcing plate.

[0191] The touchpad 2 can be a PCB circuit board, and the circuit board comprises a pressure detection coil. The pressure detection coil (induction coil) is configured to detect the position relationship with the reinforcing plate. The circuit board comprises an inductive element, a capacitive element, a grounding element, a driving chip, etc. The grounding element electrically connects the reinforcing plate and the circuit board to each other. The inductive coil is configured to detect the force applied to the circuit board. The circuit board and the reinforcing plate are bonded by silicone, and the silicone is symmetrically distributed.

[0192] Reference Figure 7 The PCB board adopts four copper layers, including a touch detection layer 202, a pressure detection layer 203, and a ground shielding layer 205. The touch detection layer 202 comprises two layers. The first layer and the second layer are capacitive touch circuits, the third layer is a ground shielding layer, and the fourth layer is arranged with a pressure sensing circuit, facing the support plate 3.

[0193] The touch module includes a vibration assembly including a vibration motor / actuator configured to generate a haptic output. The motor is attached to the circuit board by double-sided tape. The touchpad is mounted to the device by screws, nuts, and other fasteners.

[0194] The touchpad includes an inductive element including a coil, a capacitor, a resistor, and the like. The coil is a planar spiral that is disposed on the circuit board by an etching process. The planar spiral includes copper traces of the circuit board. The ground element includes a plurality of metal or conductive tape that contacts the reinforcing plate and the circuit board.

[0195] The inductive coil can be shaped as shown in Figure 8 a circle, an ellipse, or a polygon that is approximately circular, the inductive sensing distance is proportional to the outer diameter of the coil pattern.

[0196] When pressed, the steel nut fastener position serves as a fixed part, and the steel sheet between the fixed part and the silica gel deforms, thereby changing the distance between the touchpad inductive sensor and the steel sheet, thereby detecting the inductive change. At the same time, after the first controller detects that the change threshold is reached, the motor attached to the circuit board will vibrate, causing the circuit board to vibrate and form a haptic effect. At this time, the silica gel serves as a buffer elastic component to prevent the vibration from being transmitted to the reinforcing plate and the device.

[0197] In this example, the touchpad uses capacitive detection to determine the position, and inductive detection to determine the pressure. Any method that has touch operation detection function can be used to determine the touch position.

[0198] In some embodiments, capacitive sensing is used, and the presence of a fingertip and / or a capacitive stylus at or near the surface of the substrate can change the capacitance of that portion of the substrate, and thus can be registered as an input.

[0199] In some embodiments, resistive sensing is used. The resistance of an electrode in or on the circuit board (substrate) can be altered, thereby enabling recognition of an input.

[0200] The touchpad includes a cover plate and a substrate, the surface of the cover plate facing the user. The cover plate can be accessible to the user by one or more fingers and / or a stylus or other object. In some embodiments, the cover plate can be a glass cover plate. For example, a soda lime glass cover plate, an alumino-silicate glass cover plate, and the like. The cover plate surface can be sandblasted, anti-fingerprint, anti-reflective, and the like. The cover plate can be transparent, partially transparent, partially opaque, or opaque. In some embodiments, the cover plate surface can be a surface formed in one or more ways. The surface can be formed by a printing process, such as by screen printing, spraying an ink / resin.

[0201] The cover plate and the circuit board are attached using pressure-sensitive adhesive or thermosetting adhesive.

[0202] For example, the circuit board can be arranged with one or more inductive coils, in this example, four inductive coils. In some embodiments, a change in inductance of such one or more inductive elements can be detected or determined. For example, a change in inductance caused by the distance between the touchpad assembly spring plate and the base plate being brought closer together when a user presses on the cover plate or base plate can be interpreted as a force on the touchpad and thus trigger a force signal in the system. In this way, the touchpad architecture can implement an inductive force sensor that can detect inputs such as a user tapping or pressing on the touchpad.

[0203] For example, the support plate can be made of metal, such as stainless steel; it can also be made of non-metal plates, such as PMMA, etc., and a metal layer needs to be added to increase the inductive sensitivity.

[0204] For example, it also includes a near field communication module, such as an NFC module, which is arranged at the center of the touchpad module to enable the system to interconnect with external devices through NFC. The NFC coil is arranged on the fourth copper layer of the touchpad, and a ferrite film is attached to the corresponding position on the PCB to enhance the signal amount on one side of the module cover plate and shield the NFC signal on the other side.

[0205] For example, reference Figure 13 For an electrical connection diagram, the pressure detection circuit can include an inductive circuit, and the touch detection circuit can include a capacitive circuit. The inductive circuit and the capacitive circuit detect touchpad events at the same time, the capacitive circuit reports finger coordinates to the touch controller, and the touch controller reports coordinate information to the computer controller and displays it on the display. At the same time, the inductive circuit detects pressure or click signals to the LC processor, which is processed and reported to the touch controller for processing. If it is determined to be a click, the touch controller reports to the computer controller and the motor drive at the same time, and the computer recognizes the click operation and provides tactile feedback through the motor vibration. The motor drive can store multiple vibration waveforms to provide different tactile feedback for different events.

[0206] The first controller can include an LC controller, and the second controller can include a touch controller. For example, the first controller can include an LC controller and a touch controller.

[0207] Figure 13 The controller in the above can be a CPU in an electronic device.

[0208] Figure 10 A touch detection circuit is shown. The touch detection circuit can be combined with any one or more of the other examples described above.

[0209] The circuit has at least a voltage source V, an inductor L1, and a resistor R1 and a capacitor C1. The voltage source, the inductor, and the resistor are as described in Figure 10The inductor L1 is used as a force sensing sensor; and the resistor R1 is a known resistor. For example, the resistor R1 can be a combined resistance of one or more components between the inductor L1 and the ground.

[0210] In operation, the voltage source can provide a voltage in the form of an alternating current (AC) to the circuit. The first controller can measure the voltage at the node between the inductor and the resistor. When the distance between the inductor coil and the metal support plate changes, the change in the inductance causes a change in the equivalent resistance, and the first controller can determine the change in the inductance based on the measurement of the voltage at the node, and thus determine the pressure event.

[0211] The first controller can have the functions of the voltage measuring component and the inductance calculating component.

[0212] Reference Figure 11 Another touch detection circuit is shown. The touch detection circuit uses a parallel design, and the circuit includes at least a voltage source V, an inductor L2, and a resistor R2 and a capacitor C2. The voltage source, the inductor L2, and the resistor R2 are connected in parallel with each other to complete the circuit, as shown in Figure 11 The inductor L2 is used as a force sensing sensor; and the resistor R2 is a known resistor. For example, the resistor R2 can be a combined resistance of one or more components between the inductor L2 and the ground.

[0213] In operation, the voltage source can provide a voltage in the form of an alternating current (AC) to the circuit. The second controller can measure the voltage at the node between the inductor and the resistor. When the distance between the inductor coil and the metal support plate changes, the change in the inductance causes a change in the equivalent resistance, and the second controller can determine the change in the inductance based on the measurement of the voltage at the node, and thus determine the pressure event.

[0214] The second controller can have the functions of the voltage measuring component and the inductance calculating component.

[0215] For example, the relationship between the distance between the inductor coil and the metal plate and the inductance sensitivity is shown in Figure 9 Under the premise of not interfering with the structural space safety, the smaller the distance, the more sensitive the sensor. In this example, a distance of 1 mm is selected for design. The design distance should be less than 10 mm to achieve higher sensitivity.

[0216] The above-mentioned embodiments can achieve full-domain pressure touch, full-domain click, and high-precision pressure detection.
