Detailed Description

Fig. 1 is a schematic view of a touch pad structure according to an embodiment of the present invention. Fig. 2A and 2B are partially disassembled schematic views of a touch panel structure at two different viewing angles according to an embodiment of the present invention. Fig. 3A and 3B are schematic cross-sectional views of a touch pad structure of an embodiment of the invention on two different cross-sections. Referring to fig. 1, in the present embodiment, the touchpad structure 100 can be applied to a notebook computer or a docking station (docking station), and is integrated with a housing of a host of the notebook computer or a housing of the docking station. The touchpad structure 100 includes a first housing 110 and a second housing 120, wherein the first housing 110 and the second housing 120 may be a part of a housing of a host of a notebook computer or a part of a housing of a docking station, and the first housing 110 is disposed on the second housing 120.

On the other hand, the touch pad structure 100 further includes a touch pad 130, a trace 140, a first mounting seat 150 and a second mounting seat 151. The first housing 110 has an opening 111, and the touch pad 130 is disposed in the opening 111. Further, the first housing 110 further has an outer surface 112 connected to the opening 111, and the touch pad 130 is slightly lower than the outer surface 112. The touch pad 130 includes a fulcrum end 131 and a movable end 132 opposite to each other, wherein the fulcrum end 131 is connected to the first housing 110 and serves as a rotation fulcrum of the touch pad 130. In response to different operation states, if the user applies force to press the movable end 132, the touch pad 130 rotates downward relative to the first housing 110. On the contrary, if the acting force applied to the movable end 132 is removed, the touch pad 130 rotates upward relative to the first housing 110 to return to the initial state.

Referring to fig. 1, fig. 2A, fig. 2B and fig. 3A, in the present embodiment, the linkage bar 140 is located between the touch pad 130 and the second housing 120, wherein the linkage bar 140 includes a first connection portion 141, a second connection portion 142 opposite to the first connection portion 141, and a bar portion 143 located between the first connection portion 141 and the second connection portion 142, and the bar portion 143 is movably connected to the movable end 132. On the other hand, the first and second mounting

seats

150 and 151 are mounted to the first housing 110 and located between the first and

second housings

110 and 120. The first mounting seat 150 and the second mounting seat 151 are respectively located at two opposite sides of the opening 111, wherein the first connecting portion 141 is rotatably connected to the first mounting seat 150, and the second connecting portion 142 is rotatably connected to the second mounting seat 151. That is, the trace 140 has a freedom of movement that rotates relative to the first housing 110.

Further, the movable end 132 of the touch pad 130 abuts against the rod 143, and in the process that the touch pad 130 rotates downward relative to the first housing 110, the movable end 132 sinks and drives the rod 143, so that the linkage rod 140 rotates relative to the first housing 110. Because the movable end 132 is supported by the rod 143, and the movable end 132 and the rod 143 sink synchronously, the pressing feeling of the user when operating the touch pad 130 is improved, and the motion stability of the touch pad 130 is improved. Furthermore, the movable end 132 is provided with at least two positioning portions 132a disposed in parallel and facing the second housing 120, wherein the two positioning portions 132a may be positioning hooks or positioning slots, and the rod portion 143 passes through the two positioning portions 132 a.

In the process that the movable end 132 sinks and drives the rod 143 or the movable end 132 lifts and drives the rod 143, the two positioning portions 132a ensure the rod 143 and the movable end 132 move synchronously and prevent the rod 143 from separating from the movable end 132. On the other hand, the two positioning portions 132a may be symmetrically disposed on the movable end 132 to improve the smoothness of the movement of the touch pad 130. Since the positioning hooks or the positioning slots can be used as the two positioning portions 132a, the step of mounting the rod portion 143 on the two positioning portions 132a is simple and intuitive.

In addition, the first and second mounting

seats

150 and 151 are detachably mounted on the first housing 110, in the step of assembling the touch pad structure 100, the first connecting portion 141 of the linking rod 140 is first mounted on the first mounting seat 150, the second connecting portion 142 is mounted on the second mounting seat 151, then the first and second mounting

seats

150 and 151 are mounted on the first housing 110, and then the rod portion 143 of the linking rod 140 and the two positioning portions 132a of the movable end 132 of the touch pad 130 are combined, and the fulcrum end 131 of the touch pad 130 is connected to the first housing 110. Thus, the touchpad structure 100 is substantially assembled, and the assembly process is simple and intuitive.
