Description

Touch Module

This work is about a touch input device, and more particularly about a touch module.

The inductive pressure sensor installed in the known touch module is used to detect the pressure of the user touching the touch module and generate a touch signal accordingly. The principle of the inductive pressure sensor is that the touch module itself is composed of multiple plate components. When these stacked plates are touched by the user, the plates are displaced due to pressure, causing the distance or height of the gap between the plates to change. The electrode of the inductive pressure sensor detects the change in the distance or height of the gap between the plates, thereby generating different current sizes and generating pressure signals accordingly.

In general touch modules, the inductive pressure sensors are usually installed on the outer edge of the touch module. However, the most sensitive area of the touch module to pressure is the bottom plate below the corresponding touch surface. When the touch surface is subjected to pressure, it is easy to transmit the pressure to the corresponding bottom plate below. However, the bottom plate area is often blocked by other structures, and it is difficult to install a large inductive pressure sensor. Therefore, it is impossible to effectively improve the pressure sensitivity and structural simplicity.

In order to solve the problem of the known technology, this invention provides a touch module. The touch module of this invention has a pressure sensor, which is an inductive pressure sensor. The pressure sensor is arranged on the substrate below the touch area of the touch panel and is located in the elastic structure of the substrate. Since the elastic structure extends from the substrate and contacts the touch area below the touch panel, the elastic structure of the substrate not only supports the touch panel, but also can instantly transmit the pressure to the pressure sensor to improve the sensing sensitivity. The elastic structure combined with the pressure sensor can also reduce the overall thickness of the touch module and simplify the overall structure.

Furthermore, this invention can set up multiple pressure sensors to sense each other. When the pressure point is close to one of the pressure sensors, the other pressure sensor will generate a different signal. During signal processing, the different signals generated by the pressure sensors at different positions are judged. After these signals are jointly identified and processed, the signal generated by the press can be accurately sensed.

See Figure 1 for a three-dimensional view of the touch module of the first preferred embodiment of this invention, and Figure 2 for a three-dimensional exploded view of the touch module of the first preferred embodiment of this invention.

The touch module 1 of the invention includes a substrate 10, a touch panel 20, an elastic structure 30 and a pressure sensor 40. The substrate 10 has a surface 11. The touch panel 20 has a bottom surface 21. The elastic structure 30 has an elastic member 31, a spacer 32 and a groove 33. The elastic member 31 has a force-bearing surface 311 and a peripheral surface 312. The pressure sensor 40 has a sensing member 41 and a sensing portion 42. The sensing member 41 has a sensing surface 411. The sensing portion 42 has a sensing range plane 421. The touch module 1 may also include a microprocessor M (shown in FIG. 4 ), which may be disposed in the touch module 1 or in other electronic products (not shown in the figure) to which the touch module 1 is connected.

The touch panel 20 is disposed above the substrate 10 and covers the substrate 10, and the bottom surface 21 of the touch panel 20 and the surface 11 of the substrate 10 are parallel to each other. The elastic structure 30 is disposed on the surface 11 of the substrate 10. The elastic member 31 of the elastic structure 30 is disposed on the surface 11 of the substrate 10, and the force-bearing surface 311 and the peripheral surface 312 of the elastic member 31 are located on the surface of the substrate 10 and are parallel to the surface 11. The peripheral surface 312 is located around the force-bearing surface 311. In this embodiment, the peripheral surface 312 surrounds the force-bearing surface 311. The force-bearing surface 311 can be displaced relative to the surface 11 and the peripheral surface 312, and the peripheral surface 312 will not move relative to the surface 11. The force-bearing surface 311 in the non-displacement state and the peripheral surface 312 are in the same plane as the surface 11.

The spacer 32 of the elastic structure 30 is disposed on the force-bearing surface 311 of the elastic member 31, and the spacer 32 contacts and abuts the bottom surface 21 of the touch panel 20. The groove 33 of the elastic structure 30 is disposed on the substrate 10, and the groove 33 is adjacent to the elastic member 31. Preferably, the groove 33 separates the force-bearing surface 311 of the elastic member 31 from the peripheral surface 312. In this embodiment, the elastic member 31 is formed by punching or cutting the surface 11 of the substrate 10 to form a hollow groove 33, so that the groove 33 surrounds the periphery of the elastic member 31.

The pressure sensor 40 is disposed between the substrate 10 and the touch panel 20. The sensing element 41 of the pressure sensor 40 is coupled to the bottom surface 21 of the touch panel 20 and corresponds to the elastic element 31, and the sensing element 41 corresponds to the peripheral surface 312 of the elastic element 31. The sensing portion 42 of the pressure sensor 40 and the elastic element 31 of the elastic structure 30 are adjacent to each other. Preferably, the sensing portion 42 is disposed around the elastic element 31 of the elastic structure 30 and is located in the peripheral surface 312 of the elastic element 31. At the same time, the position of the groove 33 is correspondingly arranged between the sensing part 42 of the pressure sensor 40 and the elastic member 31 of the elastic structure 30. The groove 33 separates the sensing part 42 from the elastic member 31, so that the sensing range plane 421 of the sensing part 42 and the force-bearing surface 311 of the elastic member 31 are separated by the groove 33.

Furthermore, the sensing element 41 of the pressure sensor 40 is preferably embedded in or closely attached to the bottom surface 21 of the touch panel 20. The sensing surface 411 of the sensing element 41 is disposed on the bottom surface 21 of the touch panel 20 and is parallel to the bottom surface 21 of the touch panel 20. At the same time, the sensing surface 411 covers the elastic element 31 of the elastic structure 30 and corresponds to the peripheral surface 312. The sensing range plane 421 of the sensing portion 42 of the pressure sensor 40 is formed on the surface 11 of the substrate 10 and is located in the peripheral surface 312 of the elastic element 31. The sensing range plane 421 corresponds to the sensing surface 411 of the sensing element 41. Preferably, the sensing surface 411 of the sensing element 41 covers the sensing range plane 421 of the sensing portion 42, and the area of the sensing range plane 421 of the sensing portion 42 corresponds to the area of the sensing surface 411 of the sensing element 41. When the elastic element 31 is displaced after being touched, the sensing surface 411 of the sensing element 41 on the substrate 10 can be immediately driven to approach the sensing range plane 421 of the sensing portion 42 on the touch panel 20, and the distance change between the sensing surface 411 and the sensing range plane 421 can be sensed.

The sensing element 41 and the sensing part 42 of the pressure sensor 40 are electric inductive elements. The sensing element 41 is an inductive coil, which is wound along the plane of the bottom surface 21 of the touch panel 20 to form a sensing surface 411 of the sensing element 41, and the touch panel 20 can supply power to the sensing element 41, so that the sensing element 41 has a sensing effect after being powered on. Furthermore, the sensing element 41 is not provided in the area where the bottom surface 21 of the touch panel 20 is contacted and pressed by the spacer 32, so the sensing surface 411 is not formed in this area, so that the inductive coil forming the sensing surface 411 is prevented from being deformed due to the pressure of the spacer 32. The sensing part 42 is an inductive material, preferably metal. The substrate 10 of the present invention is made of metal, and the sensing part 42 is formed on the surface 11 of the substrate 10. Therefore, the sensing range plane 421 of the sensing part 42 is a partial area of the surface 11 of the substrate 10, and the sensing part 42 is also metal. This setting allows the sensing element 41 and the sensing part 42 of the pressure sensor 40 to sense each other.

The pressure sensing method of the sensing element 41 and the sensing part 42 of the pressure sensor 40 is further described. See FIG. 3A for a cross-sectional schematic diagram of the touch module of the first preferred embodiment of the present invention, FIG. 3B for a cross-sectional schematic diagram of the touch module of the first preferred embodiment of the present invention, and FIG. 4 for a signal processing flow chart of the first preferred embodiment of the present invention.

FIG3A shows the state where the touch panel 20 is not touched. When the touch panel 20 is not touched, the spacer 32 disposed on the force-bearing surface 311 of the elastic member 31 presses against the touch panel 20, so that the touch panel 20 is separated from the surface 11 of the substrate 10. At the same time, the sensing surface 411 of the sensing member 41 of the touch panel 20 and the sensing range plane 421 of the sensing portion 42 on the surface 11 of the substrate 10 are separated by a first distance D1.

FIG3B shows the state of the touch panel 20 when it is touched. When the touch panel 20 is touched, the touch panel 20 moves toward the surface 11 of the substrate 10. At this time, since the spacer 32 abuts against the touch panel 20, the touch panel 20 pushes the spacer 32 when it is pressed and displaced. The spacer 32 transmits the pressure to the force-bearing surface 311 of the elastic member 31. The force-bearing surface 311 bears the pressure and moves the elastic member 31 away from the surface 11 of the substrate 10. At this time, the distance between the sensing surface 411 of the sensing member 41 and the sensing range plane 421 of the sensing portion 42 is reduced to a second distance D2.

Based on this, it can be judged that when the distance between the sensing element 41 and the sensing part 42 of the pressure sensor 40 is larger, the current intensity generated by the two is smaller. On the contrary, when the distance between the sensing element 41 and the sensing part 42 is smaller, the current intensity is larger.

The signal processing is shown in FIG4. When the touch panel 20 is touched, the distance between the sensing surface 411 of the sensing element 41 and the sensing range plane 421 of the sensing portion 42 is reduced from the first distance D1 to the second distance D2, and the current intensity between the sensing element 41 and the sensing portion 42 changes, so that the current intensity generated by the pressure sensor 40 increases, forming an electrical signal S to the microprocessor M. After receiving the electrical signal S, the microprocessor M generates a touch signal M1.

The second best embodiment of the present invention will be described below. See Figure 5 for a three-dimensional exploded view of the touch module of the second best embodiment of the present invention, Figure 6A for a cross-sectional schematic view of the touch module of the second best embodiment of the present invention, Figure 6B for a cross-sectional schematic view of the touch module of the second best embodiment of the present invention, and Figure 7 for a signal processing flow chart of the second best embodiment of the present invention.

The second best embodiment of the present invention will be described below. See Figure 5 for a three-dimensional exploded view of the touch module of the second best embodiment of the present invention, Figure 6A for a cross-sectional schematic view of the touch module of the second best embodiment of the present invention, Figure 6B for a cross-sectional schematic view of the touch module of the second best embodiment of the present invention, and Figure 7 for a signal processing flow chart of the second best embodiment of the present invention.

The touch module 2 of the second preferred embodiment of the present invention includes a substrate 50, a touch panel 60, an elastic structure 70, a first pressure sensor 80 and a second pressure sensor 90. The substrate 50 has a surface 51. The touch panel 60 has a bottom surface 61. The elastic structure 70 has a first elastic member 71, a second elastic member 72, a first groove 73 and a second groove 74. The first elastic member 71 of the elastic structure 70 has a first spacer 711, a first force-bearing surface 712 and a first peripheral surface 713, and the second elastic member 72 has a second spacer 721, a second force-bearing surface 722 and a second peripheral surface 723.

The touch panel 60 is disposed above the substrate 50 and covers the substrate 50, and the bottom surface 61 of the touch panel 60 and the surface 51 of the substrate 50 are parallel to each other. The elastic structure 70 is disposed on the surface 51 of the substrate 50. The first pressure sensor 80 and the second pressure sensor 90 are disposed between the substrate 50 and the touch panel 60, and the first pressure sensor 80 and the second pressure sensor 90 are separated.

The first force-bearing surface 712 of the first elastic member 71 of the elastic structure 70 and the second force-bearing surface 722 of the second elastic member 72 are located on the surface 51 of the substrate 50 and are parallel to the surface 51. The first force-bearing surface 712 and the second force-bearing surface 722 can be displaced relative to the surface 51. The first peripheral surface 713 of the first elastic member 71 is adjacent to the first force-bearing surface 712, and the second peripheral surface 723 of the second elastic member 72 is adjacent to the second force-bearing surface 722. The first spacer 711 of the first elastic member 71 is disposed on the first force-bearing surface 712 of the first elastic member 71 and contacts the bottom surface 61 of the touch panel 60. Preferably, the first spacer 711 is coupled to the bottom surface 61 of the touch panel 60. The second spacer 721 of the second elastic member 72 is disposed on the second force-bearing surface 722 of the second elastic member and contacts the bottom surface 61 of the touch panel 60. Preferably, the second spacer 721 is coupled to the bottom surface 61 of the touch panel 60.

The first pressure sensor 80 corresponds to the first elastic member 71 of the elastic structure 70. The first sensing member 81 of the first pressure sensor 80 is disposed on the bottom surface 61 of the touch panel 60, and the first sensing member 81 corresponds to the first elastic member 71. The first sensing portion 82 of the first pressure sensor 80 is disposed around the first elastic member 71 and adjacent to the first force-bearing surface 712. The second sensing member 91 of the second pressure sensor 90 is disposed on the bottom surface 61 of the touch panel 60 and corresponds to the second elastic member 72, and the second sensing portion 92 of the second pressure sensor 90 is disposed around the second elastic member 72 and adjacent to the second force-bearing surface 722.

Specifically, the first sensing surface 811 of the first sensing element 81 of the first pressure sensor 80 is disposed on the bottom surface 61 of the touch panel 60 and is parallel to the bottom surface 61. At the same time, the first sensing surface 811 covers the first peripheral surface 713 of the first elastic element 71. The first sensing range plane 821 of the first sensing portion 82 of the first pressure sensor 80 is disposed around the first elastic element 71. Preferably, the first sensing range plane 821 is located in the first peripheral surface 713 of the first elastic element 71, and the first sensing range plane 821 corresponds to the first sensing surface 811 of the first sensing element 81.

The second sensing surface 911 of the second sensing element 91 of the second pressure sensor 90 is disposed on the bottom surface 61 of the touch panel 60 and is parallel to the bottom surface 61. At the same time, the second sensing surface 911 covers the second peripheral surface 723 of the second elastic element 72. The second sensing range plane 921 of the second sensing portion 92 of the second pressure sensor 90 is disposed around the second elastic element 72. Preferably, the second sensing range plane 921 is located in the second peripheral surface 723 of the second elastic element 72, and the second sensing range plane 921 corresponds to the second sensing surface 911 of the second sensing element 91.

Furthermore, the area of the first sensing range plane 821 of the first sensing portion 82 corresponds to the area of the first sensing surface 811 of the first sensing element 81, and the area of the second sensing range plane 921 of the second sensing portion 92 corresponds to the area of the second sensing surface 911 of the second sensing element 91. When the areas correspond, the sensing effect is better.

The first groove 73 and the second groove 74 of the elastic structure 70 are disposed on the substrate 50. The first groove 73 is located around the first elastic member 71 of the elastic structure 70, and the first groove 73 separates the first force-bearing surface 712 and the first peripheral surface 713 of the first elastic member 71. Since the first force-bearing surface 712 is separated from the first peripheral surface 713 by the first groove 73, the first force-bearing surface 712 is more likely to be displaced relative to the first peripheral surface 713. The second groove 74 is located around the second elastic member 72 of the elastic structure 70, and the second groove 74 separates the second force-bearing surface 722 of the second elastic member 72 from the second peripheral surface 723, so that the second force-bearing surface 722 is more easily displaced relative to the second peripheral surface 723.

It is preferred to directly open the first hollow groove 73 and the second groove 74 on the substrate 50 to form the first elastic member 71 and the second elastic member 72. Since the first groove 73 surrounds the periphery of the first elastic member 71 and the second groove 74 surrounds the periphery of the second elastic member 72, the first elastic member 71 and the second elastic member 72 have higher mobility and elasticity than the substrate 50, and are easy to sense the deformation caused by the touch pressure. At the same time, the first pressure sensor 80 and the second pressure sensor 90 can also more sensitively detect the displacement and distance change between the substrate 50 and the touch panel 60.

Continuing to explain, the pressure sensing method of the second preferred embodiment of this case is shown in Figures 6A, 6B and 7.

FIG6A shows a state where the touch panel 60 is not touched. When the touch panel 60 is not touched, the first spacer 711 disposed on the first force-bearing surface 712 of the first elastic member 71 presses against the touch panel 60, and the second spacer 721 disposed on the second force-bearing surface 722 of the second elastic member 72 presses against the touch panel 60, so that the touch panel 60 is separated from the surface 51 of the substrate 50. Furthermore, the first sensing surface 811 of the first sensing element 81 of the first pressure sensor 80 and the first sensing range plane 821 of the first sensing portion 82 maintain a basic distance d1 from each other. At the same time, the second sensing surface 911 of the second sensing element 91 of the second pressure sensor 90 and the second sensing range plane 921 of the second sensing portion 92 also maintain a basic distance d1. At this time, the distance does not change and the current intensity remains constant.

FIG6B shows the state of the touch panel 60 when it is touched. After the touch panel 60 is touched, the first elastic member 71 and the second elastic member 72 of the elastic structure 70 are displaced, and the distance between the first sensing surface 811 of the first sensing member 81 of the first pressure sensor 80 and the first sensing range plane 821 of the first sensing portion 82 changes, and the distance is shortened to a first trigger distance d2, thereby generating a first electrical signal S1 (shown in FIG7 ), and the distance between the second sensing surface 911 of the second sensing member 91 of the second pressure sensor 90 and the second sensing range plane 921 of the second sensing portion 92 changes, and the distance is lengthened to a second trigger distance d3, thereby generating a second electrical signal S2 (shown in FIG7 ). In this embodiment, the distance between the first sensing element 81 and the first sensing portion 82 changes, which is different from the distance between the second sensing element 91 and the second sensing portion 92, so as to perform a touch determination.

In detail, when the touch panel 60 is touched, a touch position 601 is generated. In this embodiment, the touch position 601 is close to the first pressure sensor 80.

When the touch position 601 is close to the first pressure sensor 80, the distance between the first sensing element 81 and the first sensing portion 82 of the first pressure sensor 80 becomes shorter. However, due to the overall rigidity of the touch panel 60, the touch panel 60 will tilt toward the touch position 601 after being pressed. At this time, since the second pressure sensor 90 is located far away from the touch position 601, the distance between the second sensing element 91 and the second sensing portion 92 of the second pressure sensor 90 will become longer after the touch panel 60 tilts. Due to the principle of inductive pressure sensors, when the distance between them is large, the current intensity generated by the two is small, and vice versa, when the distance between them is small, the current intensity is large. Therefore, the current intensity of the first electrical signal S1 generated by the first pressure sensor 80 is greater than the second electrical signal S2 of the second pressure sensor 90.

On the contrary, when the touch position 601 is close to the second pressure sensor 90, the distance between the first sensing element 81 and the first sensing portion 82 of the first pressure sensor 80 becomes longer, and the distance between the second sensing element 91 and the second sensing portion 92 of the second pressure sensor 90 becomes shorter, which will make the current intensity of the first electrical signal S1 smaller than that of the second electrical signal S2.

Therefore, according to FIG. 6A , FIG. 6B and FIG. 7 , when the touch panel 60 is touched and the touched position 601 approaches the first pressure sensor 80, the touched position 601 also approaches the first elastic member 71, and the touch pressure causes the first spacer 711 of the elastic structure 70 to push the first force-bearing surface 712 of the first elastic member 71, causing the first elastic member 71 to be displaced, and the distance between the first sensing surface 811 of the first sensing member 81 of the first pressure sensor 80 and the first sensing range plane 821 of the first sensing portion 82 is shortened from the basic distance d1 to the first triggering distance d2, and the first pressure sensor 80 generates a first electrical signal S1. However, due to the rigidity of the touch panel 60, the area on the touch panel 60 far away from the touch position 601 rises, so that the second spacer 721 of the second elastic member 72 far away from the touch position 601 also pulls the second force-bearing surface 722, causing the second force-bearing surface 722 to shift, so that the distance between the second sensing surface 911 of the second sensing member 91 of the second pressure sensor 90 and the second sensing range plane 921 of the second sensing portion 92 is increased from the basic distance d1 to a second trigger distance d3, so that the second pressure sensor 90 generates a second electrical signal S2. At this time, the first trigger distance d2 is smaller than the second trigger distance d3, so the current intensity of the first electrical signal S1 generated by the first pressure sensor 80 will be greater than the second electrical signal S2 generated by the second pressure sensor 90.

After the microprocessor M2 simultaneously receives the first electrical signal S1 generated by the first pressure sensor 80 and the second electrical signal S2 generated by the second pressure sensor 90, it compares and confirms that the current intensity of the first electrical signal S1 is greater than the second electrical signal S2 generated by the second pressure sensor 90, confirms that the current intensities of the two signals are different, and generates a pressure signal M3 accordingly.

In another case, if the touch position 601 is close to the second pressure sensor 90, the microprocessor M2 confirms that the current intensity of the first electrical signal S1 is less than the second electrical signal S2 generated by the second pressure sensor 90, and a touch signal M3 is also generated.

The above is only the best implementation example of this creation. Any other equivalent changes or modifications that do not deviate from the spirit revealed by this creation should be included in the scope of this creation.
