Detailed Description
FIG. 1 is a schematic view of a touch pad structure according to an embodiment of the invention. Fig. 2 is an exploded view of the touchpad structure of fig. 1. While orthogonal coordinates X-Y-Z are provided in this embodiment to facilitate component description. Referring to fig. 1 and fig. 2, in the present embodiment, the touch pad structure 100, for example but not limited to a notebook computer, includes a housing 110, a touch pad module 120, and a knob 130. The touch pad module 120 is disposed in the housing 110, and the touch pad module 120 has a switch SW and is driven when the touch pad module 120 is pressed by an external force. The knob 130 is rotatably disposed on the housing 110 and partially exposed out of the housing 110, as shown in fig. 1, a part of the knob 130 protrudes out of the opening 112c of the housing 110 for a user to operate. The knob 130 has a plurality of impact portions (2 impact portions P1, P2 are shown in the embodiment as an example), so that during the driving process (i.e., the process that the switch SW is pushed and driven by external force provided by the user to move), the switch SW impacts one of the impact portions (i.e., the impact portion P1 or the impact portion P2).
Referring to fig. 2 again, in the present embodiment, the housing 110 includes an upper portion 112 and a lower portion 114, and the touch pad module 120 includes a touch device 121 and a bracket 122, wherein the touch device 121 is disposed on the bracket 122 and then mounted in the recess 112a of the upper portion 112. The knob 130 is pivotally disposed on the upper portion 112 and located between the upper portion 112 and the lower portion 114. As the knob 130 rotates, the impact portions P1 and P2 sequentially expose the upper portion 112 through the opening 112b (located in the recess 112a) of the upper portion 112 and face the switch SW of the touch device 121.
Further, the knob 130 includes a body 131, a locking member 132 and the impact portions P1 and P2, the body 131 is pivotally mounted on the upper portion 112 by the locking member 132, the lower portion 114 has a rib platform 114a, the impact portions P1 and P2 are disposed on the upper surface of the body 131 of the knob 130, and the lower surface of the body 131 of the knob 130 is supported by the rib platform 114a to obtain a supporting effect. Here, the knob 130 is pivotally connected to the upper portion 112 along the Z-axis and is supported by the rib platform 114a along the Z-axis.
Fig. 3 and fig. 4 are schematic partial structural diagrams of the touch pad structure from different perspectives. Referring to fig. 2 and 4, in the present embodiment, the impact portions P1 and P2 are made of different materials, and the rotation of the knob 130 allows the impact portions P1 and P2 to be impacted by the switch SW through the opening 112b of the upper portion 112 and the notch 122a of the bracket 122, respectively, so as to receive the impact of the switch SW during the driving process and generate different loudness. Furthermore, referring to fig. 3 and fig. 4, the body 131 of the knob 130 is further divided into a first disk 131a and a second disk 131b that are coaxial with each other, the impact portions P1 and P2 are located on the first disk 131a, and the second disk 131b faces away from the switch SW.
In addition, the housing 110 has a spring arm 112d at the upper portion 112, as shown in fig. 2, the upper portion 112 of the housing 110 has a recess 112a, and the recess 112a is provided with an opening 112b near the knob 130, and the spring arm 112d is suspended in the opening 112 b. The second plate 131b has a plurality of recesses (two recesses R1, R2 are taken as an example), and the recesses R1 and R2 sequentially pass through the elastic arm 112d along with the rotation of the knob 130, so that the elastic arm 112d is temporarily clamped in one of the recesses R1 or R2. Here, the impact portions P1 and P2 of the first plate 131a and the recesses R1 and R2 of the second plate 131b are disposed alternately along the rotation direction of the knob 130 (in this embodiment, disposed alternately along the rotation angle of the knob 130 at 90 ° intervals), that is, when the elastic arm 112d is temporarily clamped in one of the recesses R1 or R2, one of the impact portions P1 or P2 faces the switch SW. In other words, the elastic arm 112d is temporarily engaged in one of the recesses R1 or R2 to provide a user with a clear operation feeling, so that the user can know which impact portion P1 or P2 is facing the switch SW at that time to provide a corresponding sound when pressing. Accordingly, the number of the recesses R1 and R2 and the number of the impact portions P1 and P2 are substantially the same to obtain a one-to-one correspondence, and the rotation axial direction (Z axis) of the knob 130 is parallel to the movement axial direction (Z axis) of the switch SW, so that the user can smoothly rotate the knob 130 to switch the impact portions P1 and P2. However, the total number of the impact portions P1, P2 and the total number of the recesses R1, R2 are not limited, and may be increased or decreased according to the need for the sound generated by the impact.
Fig. 5 and 6 are partial cross-sectional views illustrating the touch pad structure during operation. Referring to fig. 5 and fig. 6, in the present embodiment, the switch SW includes a circuit board 121b and an elastic element 121a, and the circuit board 121b is provided with a plurality of conductive parts a1 and a2, and the elastic element 121a is, for example, a dome-shaped (dome) elastic element, which has conductivity or is a metal reed (metal dome), and is supported against the conductive part a1 on the circuit board 121 b. Here, one side of the touch device 121 and one side of the bracket 122, which are respectively far away from the knob 130, are assembled on the upper portion 112 of the housing 110 by the fixing structure, and the other side of the touch device 121 and the bracket 122, which are close to the knob 130, are suspended above the impact portions P1, P2 of the knob 130, so as to form a seesaw motion mode using the fixing structure as a fulcrum, and therefore, in the driving process, the external force applied by the user presses the touch pad module 120 to drive the touch device 121 and the bracket 122 to move close to the knob 130 at the local portion of the switch SW, and the elastic element 121a is deformed after impacting the impact portion P1 or P2 on the knob 130 (the process from fig. 5 to fig. 6). That is, the elastic element 121a first collides with the impact portion (the impact portion P1 is taken as an example in the figure), and then is pressed by the impact portion P1 to generate elastic deformation, so that the central protrusion 121c of the elastic element 121a abuts against the conductive portion a2, and further the conductive portions a1 and a2 are electrically conducted with each other through the elastic element 121a, thereby generating a trigger signal. That is, the switch SW is driven and activated in the above process.
On the contrary, once the user removes the external force applied by the user, in addition to the bracket 122 and the touch device 121 moving away from the knob 130 to reset, the elastic element 121a is also restored to the state shown in fig. 5 from fig. 6.
In summary, in the above embodiments of the invention, the touch pad structure provides the knob on the pressing path of the touch pad module, and the knob is rotatably disposed on the housing, wherein the knob has a plurality of impact portions respectively located on the moving paths of the switches of the touch pad module along with the rotation of the knob, so that when the user applies a force to the touch pad module to press the touch pad module, the switches of the touch pad module move along the moving paths and impact on one of the impact portions of the knob to generate a corresponding sound.
Furthermore, the materials of the impact parts are different from each other, and corresponding sounds can be generated by the impact parts at different positions in response to the impact of the switch along with the rotation of the knob by a user. Therefore, a user can change the impact object of the switch according to the preference, so that the touch pad structure provides different operation feelings for the user.
