The above described objects, features, and advantages of the invention will be apparent from the description and appended claims

Referring to FIGS. 2 to 4, the sliding mechanism H of the embodiment of the present invention is mainly composed of a fixing member 10, a sliding member 20 and a retractable elastic module 30. The elastic module 30 has a long strip shape. For connecting the fixing member 10 and the sliding member 20, the sliding member 20 is slidable relative to the fixing member 10 in a first axial direction A through the sliding rails 11 located on the upper and lower sides of the fixing member 10. However, the slider 20 can also slide relative to the fixture 10 in the first axial direction A via a guide rod or other means. In this embodiment, the sliding mechanism H can be disposed on a first body of a handheld electronic device (similar to the display unit 100 shown in FIG. 1) and a second body (similar to the input unit 200 shown in FIG. 1). )between. For example, the fixing member 10 and the slider 20 can be fixed to the display unit 100 and the input unit 200, respectively, during assembly, whereby the effect of semi-automatic sliding between the two can be achieved. The sliding mechanism H of the present embodiment can be applied to a side-sliding handheld electronic device (similar to FIG. 1), and the sliding mechanism H of the present embodiment can also be applied to a pull-down sliding type handheld electronic device.

As shown in FIG. 2, a first slider 31 and a second slider 32 are disposed at both ends of the elastic module 30, wherein the first and second sliders 31, 32 are respectively coupled with the fixing member 10 and the slider 20 When the sliding mechanism H is in an open state, the first and second sliders 31 and 32 are separated by a distance D1. Referring to FIG. 3, when the sliding member 20 is slid to a leftward position (first axial direction A) along the guide rail 11 on the fixing member by an external force, the elastic module 30 is compressed. The first and second sliders 31, 32 are separated by a small spacing d, where d < D1.

Referring to FIG. 4, when the sliding member 20 slides to the left of the drawing relative to the fixing member 10 and beyond the critical position, the elastic module 30 is extended to both ends by its own elastic force. The two sliders 31, 32 are separated by a distance D2, where D2 > d. In other words, once the sliding member 20 slides beyond the critical position, the elastic member 30 itself can be used to force the sliding member 20 to slide to the left of the drawing relative to the fixing member 10 until the sliding mechanism H assumes a closed state. .

FIG. 5 is a schematic view showing an elastic module 30 according to an embodiment of the present invention. The elastic module 30 mainly includes a first slider 31, a second slider 32, a metal material guide G, two compression springs 33, and a torque. Spring R. As shown in FIG. 5, the first and second sliders 31 and 32 extend substantially toward the central axis C of the elastic module 30, and are located at two ends of the elastic module 30, wherein the first slider 31 and the fixing member 10 is pivotally connected to each other, and the second slider 32 is pivotally connected to the slider 20.

In the present embodiment, the first and second sliders 31, 32 are slidable along the guide rail G. In more detail, two grooves 33 are formed between the two sides of the first and second sliders 31, 32 and the guide rail G for receiving the aforementioned compression spring S, wherein the first and second sliders are 31 and 32 are respectively provided with first and second protruding rods 311 and 321 respectively. The compression spring S is substantially parallel to the central axis C, and the two ends of the compression spring S are respectively sleeved on the first and second protruding rods 311 and 321 On the outside to prevent it from falling off or ejecting the groove 33.

The two ends of the torsion spring R are respectively connected to the first and second sliders 31, 32, and the position thereof is approximately between the two compression springs S. In addition, the present embodiment further provides a torque spring R between the first and second sliders 31, 32, thereby greatly improving the output elastic force of the elastic module 30.

In summary, the present invention provides a sliding mechanism and an elastic module thereof, wherein the elastic module is provided with two compression springs and at least one torsion spring, thereby improving the output elastic force of the elastic module in a partial stroke. The invention not only can improve the elastic output of the sliding mechanism, but also can effectively save space, and is particularly suitable for being applied to various sliding type electronic devices.

Although the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
