The outer frame 221 is made of metal material and has a sheet shape and surrounds the inner frame 211. The outer frame 221 has four second pivotal slots 225 disposed on one side, two second bearing slots 226 disposed on the side opposite to the second pivotal slots 225, and two along the The second interlocking slot 227 is provided on the interlocking axis L. The second pivotal members 222 are respectively installed in the second pivotal slots 225. The second supporting members 223 are respectively installed in the second supporting slots 226. The second linkage members 224 are respectively installed in the second linkage slots 227. The second carrier board 24 is installed on the second carrier members 223.

In this embodiment, the first linkage members 214 are respectively embedded in the second linkage members 224 in a tight-fitting manner. However, this is just an example. In other modified examples, the second linkages 224 can also be used to respectively embed the first linkages 214 in a tight fitting manner, and it should not be limited to this.

The first pivotal members 212 and the second supporting members 223 are located on the same side with respect to the linkage axis L. The second pivotal members 222 and the first supporting members 213 are located on the other side with respect to the linkage axis L. The first carrier board 23 and the second carrier board 24 are connected to the circuit board 121 of the operating unit 1 to jointly carry the operating unit 1.

The seat plate unit 3 includes a plate body 31 located on the side of the biasing unit 2 opposite to the operating unit 1, and a plate body 31 protruding from the plate body 31 toward the side where the biasing unit 2 is provided and located at the center In the area 25 and corresponding to the protrusion 32 of the push switch 122, three first pivot seats 33 for pivoting the first pivot members 212, and four second pivot members for the second pivot members 222 to pivot.轴座34。 Pivot 34. The first pivot seats 33 are essentially hooks and protrude from the plate body 31 toward the side where the biasing unit 2 is provided, and are hooked on the first pivot members 212. The second pivot seats 34 are essentially hooks and protrude from the plate body 31 toward the side where the biasing unit 2 is provided and are hooked on the second pivot members 222.

It should be particularly noted that in this embodiment, the first pivot members 212, the first bearing members 213, the second pivot members 222, the second bearing members 223, and the first pivot seats 33. The number of the second pivots 34 is just an example, and those skilled in the art can use different numbers of designs according to requirements, and should not be limited to this.

Furthermore, in this embodiment, the first pivotal members 212, the first supporting members 213, the first linkage members 214, the second pivotal members 222, the second supporting members 223, the The second linkage 224 is made of plastic material and is a component independent of the inner frame 211 and the outer frame 221. The advantage of such a design is that since the structures of these components are relatively delicate and complex and difficult to manufacture, the use of plastic materials can effectively reduce the difficulty of manufacturing, thereby reducing manufacturing costs.

The operating unit 1 can move relative to the seat plate unit 3 between a preset position and a pressing position. When the user does not apply force to press the operating unit 1, the operating unit 1 is in the preset position (as shown in FIGS. 5 and 6). When the operating unit 1 of this embodiment is in the preset position, the operating unit 1 is far away from the seat plate unit 3. The push switch 122 is separated from the bump 32 (the distance is extremely short, and it is difficult to detect with the naked eye), so the push switch 122 is not deformed and cannot be triggered. Moreover, in other modified examples, the push switch 122 can also lightly touch the bump 32 but will not deform, so that it will not be triggered.

When the user presses the operating unit 1 with force, the operating unit 1 moves to the pressing position (as shown in FIG. 7). When the operating unit 1 of this embodiment is at the pressing position, the operating unit 1 approaches the seat plate unit 3, so that the first carrier board 23 and the second carrier board 24 drive the inner biasing assembly 21 and the outer biasing The components 22 are biased in the direction of the plate 31 together. At the same time, the push switch 122 is pushed by the bump 32 to deform and be triggered.

If the user presses on the operating unit 1, the position is closer to the first carrier 23. The inner biasing assembly 21 uses the first pivot seats 33 as the pivotal center axis to drive the first linkage members 214 to bias toward the plate body 31, thereby driving the second linkage members 224 With the outer frame 221. Similarly, if the user presses on the operating unit 1, the position is closer to the second carrier board 24. The outer biasing component 22 will use the second pivot seats 34 as the pivotal center axis to drive the second link members 224 to bias toward the plate body 31, thereby driving the first link members 214 With the inner frame 211. Therefore, no matter where the user presses the operating unit 1, the structural changes of the biasing unit 2 are the same, which naturally provides a uniform feedback feel everywhere, and gives the user more structural stability. Good positive impression.

In addition, since the inner frame body 211 and the outer frame body 221 in this embodiment are made of metal and are in the shape of a thin sheet, and the protrusion 32 protrudes from the plate body 31 toward the side where the biasing unit 2 is provided. , The stroke required when pressing this embodiment is quite short, which helps to reduce the overall thickness.

Moreover, since the first linkage members 214 are respectively embedded in the second linkage members 224 in a tight-fitting manner in this embodiment, the first linkage members 214 will be twisted and slightly deformed at the pressing position. Therefore, when the user removes the pressing force, the first linkages 214 will return to their original state due to their own elasticity, and then drive the operating unit 1 to return to the preset position. In other words, in addition to the elastic restoring force generated by the deformation of the push switch 122, the elastic restoring force generated by the deformation of the first linkage members 214 will also drive the operating unit 1 to return to the preset position. In this way, since the elastic restoring force of the push switch 122 and the first linkages can be shared with each other, the service life of the push switch 122 and the first linkages 214 can be prolonged, and an automatic reset function can be achieved.

In summary, the new touchpad pressing device of the present invention uses the first linkage 214 and the second linkage 224 to make the inner frame 211 and the outer frame 221 interlock with each other, so that the user can press The feel of the operation unit 1 is maintained uniformly throughout the operation unit 1, so it can indeed achieve the purpose of cost innovation.

However, the above are only examples of the present model. When the scope of implementation of the present model cannot be limited by this, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
