Description

Technical Field

[0001] The present invention relates to a touch input device, and more particularly to a touchpad. Background Art

[0002] A touchpad is an input device for manipulating the cursor of a computer, a tablet computer, etc. The touchpad senses the position and movement of the user's finger through a touch sensor and controls the movement of the cursor on the display. The force touchpad replaces the physical buttons with a haptic feedback device and a pressure sensing device, and also solves the problem that the traditional touchpad can only be pressed locally.

[0003] In order to provide a better user experience, the force touchpad is provided with a haptic feedback device to simulate the feel of physical vibration feedback. Common haptic feedback devices include, for example, piezoelectric ceramics and linear motors. Among them, for the haptic feedback device in the form of piezoelectric ceramics, multiple piezoelectric ceramics are usually arranged out of alignment on the housing of the electronic device. When the piezoelectric ceramics are pressed to generate deformation and sense the pressure, the control unit outputs a pulse signal to the piezoelectric ceramics, so that an electric field is generated in the polarization direction of the piezoelectric ceramics, and then mechanical deformation is generated to achieve vibration feedback. However, the disadvantage of piezoelectric ceramics is that the assembly of multiple piezoelectric ceramics is likely to cause the fulcrums of the piezoelectric ceramics to be non-coplanar, resulting in tolerances, so there will be a problem of inconsistent pressing and vibration feedback. Moreover, the vibration direction provided by the piezoelectric ceramics is limited to swinging back and forth in the direction perpendicular to the touch panel.

[0004] Regarding the haptic feedback device in the form of a linear motor, the linear motor is directly fixed to the bottom of the touch panel, and the internal oscillator of the linear motor is driven to swing back and forth in the direction perpendicular to the touch panel by a specific drive signal, so as to drive the overall vibration of the motor, and then drive the vibration of the touch panel to achieve vibration feedback. The disadvantages of the linear motor are that the internal structure is complex and the process difficulty is large, resulting in high production costs, and the thickness and volume of the linear motor are relatively large, occupying the battery space of the electronic device and being inapplicable to some thin and light electronic devices.

[0005] In order to be applicable to thin electronic devices and provide a more direct vibration feeling, taking the touch module (TOUCH MODULE WITH MAGNET AND MAGNETIC COIL TO GENERATE VIBRATION) of US Patent No. US11619997 as an example, a haptic feedback device is developed in which an induction wire is etched on a circuit board to form a loop of an induction coil, and then the circuit board is attached to the surface of the touch circuit board, and vibration feedback is generated by the magnetic field force with a magnetic body. Although this design can thin the module, if multiple layers of circuits are designed to increase the inductance, the process requirements of multi-layer circuit boards will be used, which is relatively expensive and prone to yield problems. Therefore, how to improve the cost of the haptic feedback device and provide more intuitive touch feedback has become a problem to be solved. Summary of the Invention

[0006] One of the objectives of the present invention is to provide an improved touchpad.

[0007] Other objectives and advantages of the present invention can be further understood from the technical features disclosed in the present invention.

[0019] The beneficial effect of the present invention is that the actuating device of the present invention is a planar coil structure formed by spirally winding a solid coil (such as a wire or an enameled wire). Compared with a circuit board with a multi-layer induction circuit that requires an etching process, the production cost is greatly reduced.

[0068] Please refer to Figure 1 and Figure 2 , the touchpad 10 of the present invention includes a substrate 11, an elastic bracket 12, and an actuation device 13. The substrate 11 has a first surface 111 and a second surface 112, and the first surface 111 and the second surface 112 are disposed opposite to each other. The elastic bracket 12 is disposed on one side of the second surface 112. The actuation device 13 includes a first actuation component 131 and a second actuation component 132. The first actuation component 131 is disposed close to the second surface 112, and the second actuation component 132 is fixed to the surface of the elastic bracket 12 facing the substrate 11. A relative movement is generated between the first actuation component 131 and the second actuation component 132 by a magnetic force to drive the relative vibration of the substrate 11 and the elastic bracket 12. Among them, the first actuation component 131 includes a coil 1311, and the coil 1311 is spirally wound to form a hollow region 13111, and the extension direction D of the hollow region 13111 is perpendicular to the substrate 11 and the elastic bracket 12. The following makes a detailed description of each component of the touchpad 10 of the present invention.

[0069] Please refer to again Figure 1, the substrate 11 has a rectangular plate appearance. The substrate 11 can be, but is not limited to, for example: a printed circuit board. Touch sensing electrodes are provided on the first surface 111. The touch sensing electrodes are used to sense the touch position of a finger and output corresponding touch sensing signals when the finger touches or presses the touchpad. A plurality of electronic components (not shown in the figure) are mounted on the second surface 112.

[0070] Please refer to again Figure 1 and Figure 2, the elastic support 12 generally has a rectangular plate shape in appearance. The material of the elastic support 12 can be, but is not limited to, for example, elastic metal materials such as aluminum or iron. The elastic support 12 includes a support area 121 and a bearing area 122. The bearing area 122 is recessed relative to the support area 121 in the negative Z-axis direction. In a preferred embodiment of the present invention, the support area 121 is connected to the bearing area 122, but this is not limiting. The support area 121 and the bearing area 122 can also be integrally formed. The support area 121 has a first thickness T1, and the bearing area 122 has a second thickness T2. Among them, the first thickness T1 is greater than the second thickness T2. The support area 121 includes a plurality of avoidance holes 1211, a plurality of first cantilever portions 1212, a plurality of second cantilever portions 1213, and a plurality of mounting holes 1214. The avoidance holes 1211 are used to provide space for various electronic components to avoid. Therefore, the avoidance holes 1211 have various different shapes and sizes, such as: rectangular, circular or irregular shapes. The first cantilever portions 1212 are formed by stamping the elastic support 12. A pressure sensor is mounted on the free end of the first cantilever portion 1212 facing the substrate 11. The first cantilever portion 1212 is used to support the pressure sensor. When the touchpad 10 is subjected to pressure, it drives the pressure sensor to elastically deform together, so that the pressure sensor can detect the pressure received by the touchpad 10. In a preferred embodiment of the present invention, the first cantilever portions 1212 are arranged at a position close to the center of the support area 121. The support area 121 has three first cantilever portions 1212, but this is not limiting. The number of the first cantilever portions 1212 can be adjusted according to the number of pressure sensors. The second cantilever portions 1213 are formed by stamping the edge of the support area 121. An elastic connecting member 12131 and a mounting pressure sensor are bonded to the surface of the free end of the second cantilever portion 1213 close to the substrate 11. The elastic connecting member 12131 is used to elastically support the substrate 11, and the elastic connecting member 12131 is bonded to the second surface 112 of the substrate 11. The elastic connecting member 12131 can be, but is not limited to, for example: silicone, silicone or rubber pad, etc. The mounting holes 1214 are used to fix the elastic support 12 to the housing of an electronic device (such as a laptop computer). In this embodiment, the mounting holes 1214 include screw holes, and the elastic support 12 is fixed to the housing of the electronic device by means of screwing, but this is not limited thereto. The bearing area 122 includes a stage portion 1221 and a plurality of connecting portions 1222. The stage portion 1221 is in a flat plate shape. The connecting portions 1222 are inclined surfaces formed by extending from the edge of the stage portion 1221 in the positive Z-axis direction. The connecting portions 1222 are used to connect the bearing area 122 and the support area 121 and make the bearing area 122 recess relative to the support area 121 in the negative Z-axis direction. The stage portion 1221 further includes two break holes 12211, two first limiting members 12212, and at least one second limiting member 12213. The two break holes 12211 are respectively and symmetrically arranged on both sides of the central position of the stage portion 1221.The two first limiting members 12212 are respectively formed by bending and protruding from the edges of the two perforations 12211 toward the positive Z-axis direction, and the two first limiting members 12212 are symmetrically arranged. At least one second limiting member 12213 is formed by bending and protruding from the side of the carrier portion 1221 away from the supporting area 121 toward the positive Z-axis direction.

[0071] Please refer again to Figure 1 and Figure 2 , the actuating device 13 includes a first actuating component 131 and a second actuating component 132. In this embodiment, the first actuating component 131 includes a coil 1311. The coil 1311 is formed by spirally winding a wire or enameled wire to form a hollow area 13111. The coil 1311 can be a multi-layer coil 1311, for example: a three-layer coil or a four-layer coil. Among them, the diameter of the coil 1311 is 0.05 mm - 0.1 mm, the number of turns of the coil 1311 is 70 - 300 turns, the thickness of the coil 1311 in the extending direction D is 0.4 mm, the long side of the coil 1311 is 8 mm, and the short side of the coil 1311 is 5 mm. However, it is not limited thereto, and its diameter, number of turns, thickness, and surface area can be adjusted according to the space configuration and vibration requirements. The second actuating component 132 includes a magnetic member 1321. The second actuating component 132 can be, for example: a magnet, but it is not limited thereto. In this embodiment, the coil 1311 is directly fixed to the second surface 112 of the substrate 11, and its fixing method can be, for example: welding, bonding, but it is not limited thereto. The coil 1311 is disposed near the central position of the carrier portion 1221. The magnetic member 1321 is correspondingly fixed to the central position of the carrier portion 1221 and covers the two perforations 12211, and the magnetic member 1321 will generally lean against the two first limiting members 12212 and at least one second limiting member 12213. The advantage of providing the first limiting member 12212 and the second limiting member 12213 is that during the process of assembling the touch panel 10, the magnetic member 1321 can be quickly positioned and more firmly fixed on the carrier portion 1221.

[0072] Please refer to Figure 3 , Figure 3Explosion schematic diagram of another embodiment of the present invention. This embodiment is generally the same as the previous embodiment, with the difference only lying in the structure of the first actuating component 131 and the presence of positioning points on the substrate 11. In this embodiment, the second surface 112 of the substrate 11 further includes a plurality of positioning points (not shown in the figure), and the plurality of positioning points are bare copper areas formed by the washing process of the printed circuit board. The first actuating component 131 further includes at least one magnetic core 1312 and a carrier 1313. The magnetic core 1312 has a cylindrical appearance, and the magnetic core 1312 passes through the hollow area 13111 of the coil 1311. In other words, the coil 1311 is wound around the magnetic core 1312. The carrier 1313 generally has a plate-like appearance and includes a top surface 13131, a bottom surface 13132, and a plurality of positioning notches 13133. The top surface 13131 and the bottom surface 13132 are oppositely arranged. The top surface 13131 is fixed to the second surface 112 of the substrate 11, the coil 1311 is fixed to the bottom surface 13132, and the magnetic core 1312 protrudes from the bottom surface 13132. The plurality of positioning notches 13133 are a plurality of chamfers formed by stamping or cutting from the edge or corner of the carrier 1313 towards the center of the carrier 1313. The positioning notches 13133 are arranged corresponding to the number and positions of the positioning points on the second surface 112 of the substrate 11, and the straight-line distance between each two positioning points will be approximately equal to the straight-line distance between each two positioning notches 13133, so that the carrier 1313 can be quickly aligned to the correct position on the second surface 112 of the substrate 11 and the two can be fixed during assembly. For example: when three positioning points are provided on the second surface 112 of the substrate 11, the carrier 1313 will also be correspondingly provided with three positioning notches 13133, and the straight-line distance between each two of the three positioning points will be approximately equal to the straight-line distance between each two of the three positioning notches 13133, but this is not limited thereto. The number, positions, and shapes of the positioning points and the positioning notches 13133 can all be adjusted according to different processes and product requirements. Among them, the fixing method between the carrier 1313 and the second surface 112 of the substrate 11 can be, for example: welding. The material of the magnetic core 1312 can be, for example: iron or plastic. The material of the carrier 1313 can be, for example: plastic, manganese-zinc alloy, tinplate, or flexible printed circuit (FPC), but this is not limited thereto.

In this embodiment, the polar direction of the magnetic member 1321 is parallel to the substrate 11 and the elastic bracket 12. When the coil 1311 is energized and an alternating magnetic field is generated by changing the current direction, an attractive force and a repulsive force are generated between the coil 1311 and the magnetic member 1321, further causing the actuating device 13 to drive the substrate 11 to vibrate back and forth relative to the elastic bracket 12 along the first vibration direction D1, where the first vibration direction D1 is parallel to the X-axis or the Y-axis.

[0074] Please refer to Figure 4C and Figure 4D , Figure 4C and Figure 4D This is a schematic diagram of the relative movement between another first actuating component 131 and the second actuating component 132 in the present invention. This embodiment is generally the same as the previous embodiment, and the difference is that in this embodiment, the polar direction of the magnetic member 1321 is perpendicular to the substrate 11 and the elastic bracket 12. When the coil 1311 is energized and an alternating magnetic field is generated by changing the current direction, an attractive force and a repulsive force are generated between the coil 1311 and the magnetic member 1321, further causing the actuating device 13 to drive the substrate 11 to vibrate back and forth relative to the elastic bracket 12 along the second vibration direction D2, where the second vibration direction D2 is parallel to the Z-axis.

[0075] Please refer to Figures 5A to 5H , this embodiment is generally the same as the previous embodiment, and the difference is that in this embodiment, the second actuating component 132' includes at least one second coil 1322, and the second coil 1322 is fixed to the surface of the elastic bracket 12 facing the substrate 11 corresponding to the coil 1311 of the first actuating component 131. As Figure 5AAs shown, the second coil 1322 is formed by spirally winding a copper wire or an enameled wire to form a second hollow region 13221. The extending direction D' of the second hollow region 13221 is parallel to the extending direction D of the hollow region 13111. In other words, the extending direction D' of the second hollow region 13221 is also perpendicular to the substrate 11 and the elastic support 12. Among them, the diameter of the second coil 1322 is 0.05 mm - 0.1 mm, the number of turns of the second coil 1322 is 70 - 80 turns, the thickness of the extending direction D' of the second coil 1322 is 0.4 mm, the long side of the second coil 1322 is 8 mm, and the short side of the second coil 1322 is 5 mm. However, it is not limited thereto, and its diameter, number of turns, thickness, and surface area can be adjusted according to the spatial configuration and the magnetic field strength requirements. In a preferred embodiment of the present invention, the second actuating assembly 132' further includes at least one second magnetic core 1323. The second magnetic core 1323 has a cylindrical appearance, and the second magnetic core 1323 is disposed through the second hollow region 13221. In other words, the second coil 1322 will be wound around the second magnetic core 1323. Among them, the material of the second magnetic core 1323 can be, for example: iron or plastic, but it is not limited thereto.

[0076] For the following Figures 5A to 5H A further description will be made on the detailed implementation manner of the relative movement between the first actuating assembly 131 and the second actuating assembly 132'.

[0077] Please refer to again Figures 5A to 5B , in this embodiment, the first actuating assembly 131 includes a coil 1311, and the second actuating assembly 132' includes a second coil 1322. The second coil 1322 is energized and a fixed magnetic field is generated by fixing its current direction. The polar direction of the second coil 1322 will be perpendicular to the substrate 11 and the elastic support 12. When the coil 1311 is energized and an alternating magnetic field is generated by changing the current direction, an attractive force and a repulsive force are generated between the coil 1311 and the second coil 1322, further causing the actuating device 13 to drive the substrate 11 to vibrate back and forth relative to the elastic support 12 along the second vibration direction D2. Among them, the second vibration direction D2 is parallel to the Z axis.

[0078] Please refer to again Figures 5C to 5D , its structure is the same as Figure 5A and Figure 5BSubstantially the same, with the difference only lying in the number of the second coils 1322. In this embodiment, the second actuating component 132' includes two second coils 1322 with the same structure. The two second coils 1322 are respectively energized and generate a fixed magnetic field by fixing their current directions. The polar directions of the two second coils 1322 will be perpendicular to the substrate 11 and the elastic bracket 12. When the coil 1311 is energized and an alternating magnetic field is generated by changing the current direction, an attractive force and a repulsive force are generated between the coil 1311 and the two second coils 1322, further causing the actuating device 13 to drive the substrate 11 to vibrate back and forth relative to the elastic bracket 12 along the first vibration direction D1. Among them, the polar directions of the two second coils 1322 are opposite, and the first vibration direction D1 is parallel to the X-axis or the Y-axis.

[0079] Please refer to again Figures 5E to 5F , Figure 5E and Figure 5F The structure is substantially the same as that of the foregoing embodiment, with the difference being that in this embodiment, the first actuating component 131 includes two coils 1311 with the same structure, and the second actuating component 132' includes one second coil 1322. The second coil 1322 is energized and generates a fixed magnetic field by fixing its current direction. The polar direction of the second coil 1322 will be perpendicular to the substrate 11 and the elastic bracket 12. When the two coils 1311 are energized and an alternating magnetic field is generated by changing the current direction, an attractive force and a repulsive force are generated between the two coils 1311 and the second coil 1322, further causing the actuating device 13 to drive the substrate 11 to vibrate back and forth relative to the elastic bracket 12 along the first vibration direction D1. Among them, the polar directions of the two coils 1311 are opposite, and the first vibration direction D1 is parallel to the X-axis or the Y-axis.

[0080] Please refer to again Figures 5G to 5H , the structure of which is the same as that of Figure 5E and Figure 5F Substantially the same, with the difference only lying in the number of the second coils 1322. In this embodiment, the second actuating component 132' includes two second coils 1322 with the same structure. The two second coils 1322 are respectively energized and generate a fixed magnetic field by fixing their current directions. The polar directions of the two second coils 1322 will be perpendicular to the substrate 11 and the elastic bracket 12. When the two coils 1311 are energized and an alternating magnetic field is generated by changing the current direction, an attractive force and a repulsive force are generated between the two coils 1311 and the two second coils 1322, further causing the actuating device 13 to drive the substrate 11 to vibrate back and forth relative to the elastic bracket 12 along the second vibration direction D2. Among them, the polar directions of the two coils 1311 are opposite, the polar directions of the two second coils 1322 are opposite, and the second vibration direction D2 is parallel to the Z-axis.

[0081] Please refer to Figure 6, this embodiment is generally the same as the foregoing embodiment, except that in this embodiment, the second actuating component 132” includes a plurality of magnetic members 1321, and the plurality of magnetic members 1321 are arranged in a Halbach Array, especially a linear Halbach Array. The second actuating component 132” formed by the linear Halbach Array can increase the magnetic field on one side of the array and cancel the magnetic field on the other side. Figure 6 In the arrangement of the plurality of magnetic members 1321 shown, the magnetic field intensity on the upper surface of the second actuating component 132” will be greater than that on the lower surface. Therefore, the upper surface of the second actuating component 132” is arranged to face the substrate 11 and the first actuating component 131.

[0082] In summary, the advantages of the present invention are as follows:

[0083] 1. The actuating device of the present invention is a planar coil structure formed by helically winding a solid coil (such as a wire or an enameled wire). Compared with a multi-layer induction circuit board that requires an etching process, the production cost is greatly reduced. The present invention is also relatively easy to repair and disassemble, and the inductance value of the coil can be further changed by adjusting the diameter, total length or material of the coil to adjust the vibration amplitude. The tolerance and elastic space in design are relatively high.

[0084] 2. The actuating device of the present invention is provided with a carrier, which makes it convenient to manage the wires of the solid coil and prevents them from scattering. The present invention is provided with a positioning notch on the carrier and positioning points on the substrate, which is convenient for improving the assembly efficiency and reducing the defects of the product.

[0085] 3. The elastic bracket of the present invention is provided with two parts: a support area and a bearing area. Since the second actuating component is arranged on the bearing area, and the thickness of the plate body in the bearing area is less than the thickness of the plate body in the support area, the overall thickness of the touch panel can be effectively reduced.

[0086] However, as described above, it is only a preferred embodiment of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims of the present invention and the content of the invention description still fall within the scope covered by the patent of the present invention. In addition, any embodiment or claim of the present invention does not have to achieve all the purposes, advantages or features disclosed in the present invention. In addition, the abstract part and the title are only used to assist in searching the patent document and do not limit the scope of rights of the present invention. In addition, the terms “first”, “second” and the like mentioned in this specification or claims are only used to name elements or distinguish different embodiments or scopes, and do not limit the upper or lower limits of the number of elements.
