Detailed ways

First please refer to Fig. 1, the sliding mechanism in this embodiment can be used as a sliding module in a slide-type mobile phone, for example, which mainly includes a first member 10, a second member 20, two projections R and Two flexible elastic pieces S, wherein the protrusion R is pivotally arranged on the first member 10 , and the flexible elastic piece S is disposed on the second member 20 and corresponds to the aforementioned protrusion R. As shown in Figure 1, the first and second members 10 and 20 are provided with corresponding first and second sliding parts 101 and 201 respectively, wherein the first and second sliding parts 101 and 201 are parallel to a first direction D1 and are connected to each other in a slidable manner, so that the second member 20 can slide relative to the first member 10 along the first direction D1 or the second direction D2.

Next, please refer to Fig. 2, the flexible elastic piece S in this embodiment has two fixed parts S1 and an elastic part S2, wherein the fixed part S1 is U-shaped, and the elastic part S2 is formed between the two fixed parts S1 And has an arc structure. As shown in Figure 2, the second member 20 has two sidewalls 202 parallel to the second sliding part 201 inside, wherein each sidewall 202 is respectively provided with two grooves 203, the flexible elastic piece S is two The fixing parts S1 at the ends are engaged and fixed in the grooves 203 respectively.

Referring to FIG. 3 again, when the second member 20 is at an initial position X1 relative to the first member 10 , the protrusion R is close to the fixing portion S1 below the flexible elastic piece S. As shown in FIG. Next, when the second member 20 is pushed by an external force to move from the initial position X1 to a first position A1 along the first direction D1 (as shown in FIG. 4 ), the aforementioned protrusion R is in contact with the elastic portion S2 on the elastic portion A first contact point P1 on S2. In particular, since the elastic portion S2 is deformed by being pressed by the protrusion R at this time, and the contact position of the protrusion P and the elastic portion S2 has exceeded a critical point C on the arc-shaped elastic portion S2, when the aforementioned external force is released, , the elastic portion S that was originally deformed by force will act a first elastic force on the bump P, forcing the second member 20 to move continuously along the first direction D1 relative to the first member 10 to a target position X2 (as shown in FIG. 5 ). , wherein the tangent direction of the aforementioned critical point C is substantially parallel to the first direction D1.

It should be noted that the bump R in this embodiment has a circular contact surface abutting against the elastic portion S2, wherein the bump R is pivotally arranged on the first member 10 and can roll on the elastic portion S . However, the aforementioned bump R can also be fixed on the first member 10 , or the bump R and the first member 10 can be integrally formed so that the bump R can slide on the elastic portion S.

Referring to FIG. 6 again, when the second member 20 is pushed by an external force and slides from the initial position X1 relative to the first member 10 to a second position A2, the above-mentioned protrusion R and the elastic portion S2 are in contact with the elastic portion S2. At this time, although the elastic part S2 is deformed by being squeezed by the bump R, the position of the second contact point P2 does not exceed the critical point C on the arc-shaped elastic part S2, so when the aforementioned external force is released , the elastic portion S2 will act a second elastic force on the bump R, so that the second member 20 returns to the initial position X1 along the opposite direction (the second direction D2) of the first direction D1 (as shown in FIG. 3 ). Wherein, the aforementioned critical point C is located between the second contact point P2 and the aforementioned first contact point P1.

To sum up, when it is desired to slide the second member 20 from the initial position X1 to the target position X2, it is only necessary to push the second member 20 in the first direction D1, and make the contact point between the protrusion R and the elastic portion S2 exceed the elasticity The critical point C on the part S2 is enough (as shown in the first contact point P1 in FIG. 4 ), and then the second member 20 can be automatically pushed to the position completely by the elastic force of the elastic part S2, so no full force is required. Conversely, if the contact point between the bump R and the elastic portion S2 does not exceed the critical point C (as shown in the second contact point P2 in FIG. 6 ), when the external force is released, the elastic portion S2 will exert a reverse elastic force to make The second member 20 returns to the initial position X1. Since the sliding mechanism of the present invention not only has a positioning function, but also improves the convenience of operation, it can be widely used in the sliding mechanism of various electronic devices.

Although the present invention has been disclosed in combination with the above-mentioned preferred embodiments, it is not intended to limit the present invention. Any person familiar with the art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The scope of protection of the present invention should be defined by the appended claims.
