[0025] ​​​The present invention provides a touchpad device that can be used with any suitable electronic device requiring touch / press input / control, such as, but not limited to, laptop computers and tablet computers. In other embodiments, the touchpad device can be a standalone device that can be connected to a non-portable or portable electronic device. Users can thereby manipulate the touchpad device by sliding or pressing their fingers, thereby controlling the operation of the electronic device.

[0026] refer to Figures 1 to 4 , Figure 1 is a schematic structural diagram of a touch panel device according to a first embodiment of the present invention, Figure 2 and Figure 3 They are Figure 1 A partially enlarged top view and a partially enlarged bottom view of the bracket in FIG. Figure 4 for Figure 1 A schematic cross-sectional view of the touch panel device in FIG. Figures 1 to 4 As shown, the touchpad device 1 includes a touchpad 10 and a bracket 20. The touchpad 10 is used to sense touch operations. The bracket 20 is disposed below the touchpad 10 to support the touchpad 10. The bracket 20 has multiple sets of retaining structures 24, and each set of retaining structures 24 includes two interference members (e.g., interference member 210 and interference member 220). The two interference members extend from the bracket 20 such that the two interference members at least partially overlap in the stacking direction of the touchpad 10 and bracket 20 (e.g., the Z-axis direction).

[0027] In particular, the touchpad 10 can be a plate body extending along an XY plane, and the touchpad 10 includes a circuit board 11 and a touch surface (e.g., a surface of a cover plate 12). The circuit board 11 can be a general printed circuit board, a flexible printed circuit board, or a rigid-flex printed circuit board (Rigid-Flex PCB). The circuit board 11 has touch circuitry and switch circuitry. The touch circuitry is used to sense a touch operation on the touch surface, such as a human hand or a stylus, and can include a sensing unit and a sensing line (not shown). The switch circuitry includes switches 111 and a switch line (not shown) to trigger a press signal when the touch surface is pressed with a certain force. The switches 111 of the touchpad 10 are disposed on a bottom surface of the circuit board 11, and are preferably located at or near the center of the touchpad 10, but are not limited thereto. Depending on the actual application, the switches 111 can be located at any suitable position of the touchpad 10. In an embodiment, the switches 111 can be button switches or micro switches, and the support 20 preferably has a trigger portion 25 corresponding to the switches 111. The trigger portion 25 is disposed corresponding to the switches 111, so that the switches 111 are pressed against the trigger portion 25 to generate a press signal in response to a user's pressing operation on the touch surface. In an embodiment, the touchpad 10 includes the cover plate 12, and the touch surface can be an upper surface of the cover plate 12. For example, the cover plate 12 can be a glass plate or a polymer plate disposed on the circuit board 10 for a user to touch or press.

[0028] The support 20 includes a frame 21, a flap portion 22, and elastic arms 23. The elastic arms 23 connect the flap portion 22 and the frame 21, and a top surface 202 of the flap portion 22 is closer to the touchpad 10 than a top surface 201 of the frame 21. The frame 21 has frame openings 203, the flap portion 22 is disposed in the frame openings 203, and the elastic arms 23 can support the flap portion 22 to move relative to the frame 21. In particular, the frame 21 includes an outer frame 211 and a central rib 212 connected to inner sides of the outer frame 211 to define the frame openings 203. For example, the support 20 can be a single sheet of metal punched to form a rectangular frame having the frame 21, the flap portion 22, and the elastic arms 23, thereby simplifying the assembly process and increasing the utilization of space in the structure. The outer frame 211 of the frame 21 can be a hollow rectangular frame. The central rib 212 of the frame 21 is preferably connected to central inner sides of opposite long sides of the outer frame 211 in a short axis direction of the outer frame 211 to define two frame openings 203 on both sides of the central rib 212 in a long axis direction of the outer frame 211. The two flap portions 22 are respectively located in the two frame openings 203 and are connected to the outer frame 211 or the central rib 212 of the frame 21 by the elastic arms 23.

[0029] The wing portion 22 may be an E-shaped plate. Specifically, the wing portion 22 may include two outer wings 221 and an inner wing 222 disposed between the two outer wings 221. In one embodiment, the inner wing 222 may have a component hole 204 to allow the electronic components below the circuit board 11 to pass through. Figure 2 As shown, the two outer wings 221 are disposed along the short axis of the outer frame 211 and adjacent to corresponding long sides of the outer frame 211, corresponding to the four corners of the frame opening 203. The inner wings 222 are partially connected to the two outer wings 221, spaced apart from each other. The junction between the inner wings 222 and the outer wings 221 is preferably adjacent to the side of the outer frame 211 away from the central rib 212. The elastic arms 23 are disposed between the outer wings 221 and the inner wings 222, adjacent to the junction between the two wings, to provide support to the corners of the touchpad 10. In this embodiment, the elastic arms 23 are bent strip-like structures (e.g., L-shaped strips) and include an inclined section 231 and an extended section 232. The inclined section 231 bends upward relative to the extended section 232 to connect to the inner wing 222. The extended section 232 extends along the inner wing 222 and bends outward near the central rib 212 to connect to the inner side of the long side of the outer frame 211. Furthermore, by adjusting the bending angle of the elastic arm 23, the support force on the corners of the touchpad 10 can be increased. The ends of the elastic arm 23 are respectively connected to the outer frame 211 and the wing portion 22. In the stacking direction, the end of the elastic arm 23 connected to the wing portion 22 is preferably higher than the end of the elastic arm 23 connected to the outer frame 211, so that the top surface 202 of the wing portion 22 is closer to the touchpad 10 than the top surface 201 of the frame body 21 (or outer frame 211). In this way, the bracket 20 can be coupled to the touchpad 10 via the top surface 202 of the wing portion 22, allowing the bracket 20 to support the touchpad 10 in a suspended manner via the elastic arm 23. For example, the top surface 202 of the wing portion 22 can be bonded to the bottom surface of the circuit board 11 of the touch panel 10 by any suitable means, such as adhesive bonding. Furthermore, the bonding surface between the top surface 202 of the wing portion 22 and the circuit board 11 can be enhanced by microstructuring or chemical methods to improve the rigidity of the touch panel 10.

[0030] In one embodiment, the bracket 20 preferably has four or more sets of limiting structures 24. The four sets of limiting structures 24 are evenly arranged around the touch panel 10 to limit the height of the touch panel 10 and serve as fulcrums to provide a sense of strength on the opposite sides of the center of the touch panel 10. The two interference members of each set of limiting structures 24 may include a fixed interference member 210 and a movable interference member 220. Figure 2As shown in the enlarged view (a) and the enlarged view (b), the fixed interference members 210 extend from the frame 21, and the movable interference members 220 extend from the flap portions 22. In the stacking direction (e.g., the Z-axis direction), the fixed interference members 210 and the movable interference members 220 at least partially overlap, such that when the touchpad 10 moves relative to the frame 21, the fixed interference members 210 and the movable interference members 220 can interfere to generate a limiting effect. For example, in this embodiment, each flap portion 22 can have four movable interference members 220, and each outer flap 221 is provided with two movable interference members 220. From another perspective, the two movable interference members 220 respectively extend downward from both ends of the outer flap 221 to be adjacent to the central rib 212 and the outer frame 211 on the opposite side. Corresponding to the arrangement of the movable interference members 220, the four fixed interference members 210 respectively bend from the inner side of the outer frame 211 towards the touchpad 10 (e.g., upwards) to be above and at least partially overlap with the corresponding movable interference members 220. In this way, four sets of limiting structures 24 are formed in each frame opening 203, so that the support 20 has a total of eight sets of limiting structures 24, corresponding to the four corners of the frame 21 and the four corners of the two frame openings 203 adjacent to the central rib 212. In an embodiment, the fixed interference members 210 and the movable interference members 220 can be hooks arranged in pairs, but are not limited thereto.

[0031] As shown in the enlarged view (a) and the enlarged view (b), the fixed interference members 210 extend from the frame 21, and the movable interference members 220 extend from the flap portions 22. In the stacking direction (e.g., the Z-axis direction), the fixed interference members 210 and the movable interference members 220 at least partially overlap, such that when the touchpad 10 moves relative to the frame 21, the fixed interference members 210 and the movable interference members 220 can interfere to generate a limiting effect. For example, in this embodiment, each flap portion 22 can have four movable interference members 220, and each outer flap 221 is provided with two movable interference members 220. From another perspective, the two movable interference members 220 respectively extend downward from both ends of the outer flap 221 to be adjacent to the central rib 212 and the outer frame 211 on the opposite side. Corresponding to the arrangement of the movable interference members 220, the four fixed interference members 210 respectively bend from the inner side of the outer frame 211 towards the touchpad 10 (e.g., upwards) to be above and at least partially overlap with the corresponding movable interference members 220. In this way, four sets of limiting structures 24 are formed in each frame opening 203, so that the support 20 has a total of eight sets of limiting structures 24, corresponding to the four corners of the frame 21 and the four corners of the two frame openings 203 adjacent to the central rib 212. In an embodiment, the fixed interference members 210 and the movable interference members 220 can be hooks arranged in pairs, but are not limited thereto. Figure 2 As shown in the enlarged view (c), the trigger portion 25 is arranged on the central rib 212 corresponding to the switch 111. The trigger portion 25 can be a structure protruding upward from the support 20 and located directly below the switch 111, and the trigger portion 25 and the switch 111 can have a gap or no gap therebetween. In an embodiment, the trigger portion 25 can be a tube column with internal threads, and the switch 111 generally includes a metal dome. By controlling the length of the bolt screwed into the tube column, the pre-press between the trigger portion 25 and the metal dome can be adjusted, thereby the pressing feeling can be adjusted.

[0032] Furthermore, the support 20 can further have at least one reinforcing structure (e.g., reinforcing structure 26, reinforcing structure 27), and the at least one reinforcing structure includes a raised rib, a flange, a reinforcing member, or any combination thereof. As shown in the enlarged view (a) and the enlarged view (b), the central rib 212 is formed with a plurality of raised ribs as reinforcing structures 27 in the direction of the elongated axis to enhance the structural strength of the central portion of the frame 21. Figure 1 As shown in the enlarged view (a) and the enlarged view (b), the central rib 212 is formed with a plurality of raised ribs as reinforcing structures 27 in the direction of the elongated axis to enhance the structural strength of the central portion of the frame 21. Figure 1 , Figure 2 As shown in the enlarged view (a) and the enlarged view (b), the central rib 212 is formed with a plurality of raised ribs as reinforcing structures 27 in the direction of the elongated axis to enhance the structural strength of the central portion of the frame 21. Figure 3 As shown in the enlarged view (a) and the enlarged view (b), the flap portion 22 can have a downwardly bent flange as a reinforcing structure 26 to enhance the structural strength of the flap portion 22. In other embodiments, the reinforcing structure 26, the reinforcing structure 27 can be additional reinforcing members, such as welding additional reinforcing metal strips on the support 20 (see the reinforcing structure 26A of Figure 7 .

[0033] As shown in Figure 1 , the bracket 20 can also have a locking hole 28 and a positioning hole 29 for locking and positioning with the housing 60 (shown in Figure 9 ). In one embodiment, the locking hole 28 is disposed at the side of the bracket 20, and the positioning hole 29 is preferably disposed adjacent to the limiting structure 24. In this way, the bracket 20 can be fixed to the housing 60 (to be described later).

[0034] Please refer to Figure 5 , Figure 5 for a structural schematic view of a touchpad device according to a second embodiment of the present application. In this embodiment, the touchpad 10 is omitted, and only the differences between this embodiment and the previous embodiment will be described later. The same or similar details (such as the details of the touchpad 10 and the bracket 20) can be referred to the related descriptions of the previous embodiment. As shown in Figure 5 , the touchpad device 1 can also include a reinforcing plate 30. The reinforcing plate 30 is disposed between the circuit board 11 and the bracket 20, and is used to increase the structural strength of the touchpad. The reinforcing plate 30 preferably has a structure and shape corresponding to the bracket 20. For example, the reinforcing plate 30 can have an outer frame 311 and a central rib 312 connected to the inner side of the outer frame 311. The central rib 312 and the outer frame 311 jointly define two openings 31, and a through hole 32 is formed in the central rib 312. The outer frame 311 of the reinforcing plate 30 corresponds to the outer frame 211 of the bracket 20, and the central rib 312 of the reinforcing plate 30 corresponds to the central rib 212 of the bracket 20. The openings 31 allow the flap portion 22 of the bracket 20 to pass through, and the through hole 32 corresponds to the trigger portion 25 of the bracket 20. The reinforcing plate 30 can be combined with the bottom surface of the circuit board 11 by any suitable means (such as adhesion), the flap portion 22 of the bracket 20 is combined with the bottom surface of the circuit board 11 through the openings 31 of the reinforcing plate 30, and the reinforcing plate 30 is clamped between the bottom surface of the circuit board 11 and the frame body 21 of the bracket 20. The switch 111 (or metal dome) of the circuit board 11 corresponds to the trigger portion 25 of the bracket 20 through the through hole 32 of the reinforcing plate 30.

[0035] Please refer to Figure 6 and Figure 7 , Figure 6 for a structural schematic view of a bracket according to a second embodiment of the present application, Figure 7 for a partial enlarged bottom view of the bracket in Figure 6 . Only the differences between this embodiment and the previous embodiment will be described later. The same or similar details (such as the details of the frame body 21, the flap portion 22, the limiting structure 24, etc.) can be referred to the related descriptions of the previous embodiment. As shown in Figure 6 and Figure 7As shown, the elastic member 23A of the bracket 20A is connected between the flap portion 22 and the central rib 212, and the elastic arm 23 is connected to one end of the central rib 212 adjacent to the trigger portion 25A or the center of the central rib 212. In this embodiment, the distance between the adjacent limiting structures 24 on the same side is relatively small, i.e. more concentrated towards the middle, and is less favorable for limiting the force on the opposite diagonal when pressed. Therefore, increasing the distance between the adjacent limiting structures 24 on the same side (e.g. as in the embodiments of Figure 1 and Figure 8 ), and making the limiting structures 24 relatively close to the corners of the touchpad 10, can have a better limiting effect. The trigger portion 25A can not have threads. In addition, the reinforcing structure 26A is an additional metal strip (e.g. welded, adhered). The central rib 212 has a strip-shaped convex rib and an arc-shaped convex rib around the trigger portion 25A as the reinforcing structure 27A and the reinforcing structure 27B, respectively.

[0036] Please refer to Figure 8 , Figure 8 for the structure diagram of the bracket of the third embodiment of the present application. Hereinafter, only the differences between this embodiment and the previous embodiments will be described, and the same or similar details (e.g. the details of the frame 21, the flap portion 22, the limiting structure 24, etc.) can be referred to the relevant descriptions of the previous embodiments. As shown in Figure 8 , the elastic member 23B of the bracket 20B is connected between the flap portion 22 and the outer frame 211, and the two adjacent elastic arms 23 on the same side extend in the same direction to be connected to the same side of the outer frame 211. In this embodiment, the elastic arm 23B is inclined upward from the inner side of the short side of the outer frame 211 in the direction of the central rib 212 to connect the flap portion 22 near the connection between the inner flap and the outer flap (similar to the embodiment of Figure 1 ).

[0037] Please refer to Figures 9 to 11 , Figure 9 and Figure 10 for the top view and bottom view exploded schematic diagrams of the touchpad device of the third embodiment of the present application, Figure 11 is the cross-sectional schematic diagram of the touchpad device in Figure 9 . As shown in Figures 9 to 11As shown, in one embodiment, the touchpad device 1 can further include a housing 60, wherein the housing 60 has a housing opening 61, and the touchpad 10 is disposed in the housing opening 61. In particular, the housing 60 can be a device housing of an electronic device, such as a keyboard upper housing of a notebook computer. The housing opening 61 is preferably sized and shaped to correspond to the touchpad 10, such that when the touchpad 10 is disposed in the housing 60, the touch surface (e.g., the cover plate 12) can be exposed from the housing opening 61 for user operation. For example, the housing opening 61 can be a rectangular opening. In particular, the housing 60 has a coupling hole 65 to correspond to the locking hole 28 of the touchpad device 1. For example, the locking hole 28 is preferably disposed on a lower surface of the housing 60, adjacent to the housing opening 61, and the touchpad device can be locked to the coupling hole 65 of the housing 60 from the bottom by a fastener 70. In addition, the housing 60 and the bracket 20 can have corresponding positioning mechanisms, such as a protrusion 67 and a positioning hole 29, which can be aligned / positioned before being locked by the fastener 70, to facilitate assembly.

[0038] It should be noted that the limiting structure 24 in the above embodiments is disposed below (or on the inner side of) the touchpad 10, but it is not limited thereto. Depending on actual applications, the limiting structure 24 can be disposed on the outer side of the touchpad 10.

[0039] In summary, the present application provides a limiting mechanism by a single bracket, which increases the utilization of the structure in space. Furthermore, the touchpad device of the present application employs a single bracket with a double-layer structure, and the high-layer top surface (e.g., the top surface of the wing portion) of the bracket is combined with the touchpad to support the displacement of the touchpad relative to the low-layer (e.g., the frame) of the bracket, thereby providing a pressing feeling and improving the operation comfort of the user.

[0040] Obviously, the above embodiments of the present application are merely exemplary and are not intended to limit the embodiments of the present application. Based on the above description, other different forms of changes or modifications can be made by those skilled in the art, and it is impossible to enumerate all the embodiments here.
