DETAILED DESCRIPTION
An embodiment of a slide apparatus is hereinafter described with respect to FIG. 2A, FIG. 2B and FIG. 2C. The slide apparatus comprises a first member 10 and a second member 20, both of which are relatively movable. The second member 20 is movable between a first position and a second position in relation to the first member 10, with a central position therebetween. The first position and the second position can alternatively be an open position and a closed position. For example, when the second member 20 in FIG. 2A is in the first position (the closed position), the second member 20 in FIG. 2B is in the central position, and the second member 20 in FIG. 2C is in the second position (the open position).
Further, a torque-retaining assembly is disposed between the first member 10 and the second member 20. When the second member 20 moves from the first position (as shown in FIG. 2A) to the central position (as shown in FIG. 2B), or moves from the second position (as shown in FIG. 2C) to the central position in relation to the first member 10 by an external force, the torque-retaining assembly generates a torque, driving the second member 20 from the central position to the first position or the second position.
In this case, the second member 20 is to be moved from the first position as shown in FIG. 2A to the second position as shown in FIG. 2C, the second member 20 is moved from the first position to the central position as shown in FIG. 2B, and torque generated by the torque-retaining assembly drives the second member 20 from the central position to the second position. Similarly, the second member 20 is to be moved from the second position as shown in FIG. 2C to the first position as shown in FIG. 2A, the second member 20 is moved from the second position to the central position as shown in FIG. 2B, and torque generated by the torque-retaining assembly drives the second member 20 from the central position to the first position. The substantial structure of the torque-retaining assembly is described later.
FIG. 3 shows an embodiment of an electronic device. The electronic device applies the slide apparatus, which comprises a first member 10, a second member 20, a first sliding track 30, a second sliding track 40, an elastic element 50, a first slide module and a second slide module. The elastic element 50, the first slide module and the second slide module constitute the torque-retaining assembly.
The first member 10 and the second member 20 can alternatively be a body and a sliding cover of the electronic device. In FIG. 3, for example, the first member 10 is the body and the second member 20 is the sliding cover, but the alternative structure is also applicable. The second member 20 is movable between a first position and a second position in relation to the first member 10, with a central position therebetween, as shown in FIG. 2A to FIG. 2C.
The first slide module and the second slide module are symmetrically disposed on the first member 10. The structures of the two slide modules are hereinafter described in detail.
FIG. 4A and FIG. 4B show the elements of the first slide module. The first slide module comprises a first supporting structure 60 and a first gear 70. The first supporting structure 60 is disposed on the first member 10 to support the first gear 70. The first supporting structure 60 comprises a first limiting portion 62 and a first elastic cantilever beam 64. A first fixed end 64A of the first elastic cantilever beam 64 is connected to the first limiting portion 62, and a first free end 64B of the first elastic cantilever beam 64 is connected to a first rotating shaft 72 of the first gear 70. Further, the upper portion of the first supporting structure 60 comprises a first opening 66, exposing a part of the first gear 70.
The first gear 70 is rotatably disposed at the first free end 64B of the first elastic cantilever beam 64 by the first rotating shaft 72. The first rotating shaft 72 protrudes from one side of the first gear 70. On the other side of the first gear 70, a first fixing shaft 74 is provided. Thus, the first gear 70 can move between a first limited position and a first free position by the first elastic cantilever beam 64.
Referring to FIG. 4C, when the first gear 70 is in the first limited position, the first gear 70 is limited by the first limiting portion 62, and is not rotatable in relation to the first supporting structure 60. Referring to FIG. 4D, when the first gear 70 is in the first free position, the first gear 70 is released from the first limiting portion 62, and is rotatable in relation to the first supporting structure 60.
FIG. 5A and FIG. 5B show the elements of the second slide module. The second slide module comprises a second supporting structure 80 and a second gear 90. The second supporting structure 80 is disposed on the first member 10 to support the second gear 90. The second supporting structure 80 comprises a second limiting portion 82 and a second elastic cantilever beam 84. A second fixed end 84A of the second elastic cantilever beam 84 is connected to the second limiting portion 82, and a second free end 84B of the second elastic cantilever beam 84 is connected to a second rotating shaft 92 of the second gear 90. Further, the upper portion of the second supporting structure 80 comprises a second opening 86, exposing a part of the second gear 90.
The second gear 90 is rotatably disposed at the second free end 84B of the second elastic cantilever beam 84 by the second rotating shaft 92. The second rotating shaft 92 protrudes from one side of the second gear 90. On the other side of the second gear 90, a second fixing shaft 94 is provided. Thus, the second gear 90 can move between a second limited position and a second free position by the second elastic cantilever beam 84.
Referring to FIG. 5C, when the second gear 90 is in the second limited position, the second gear 90 is limited by the second limiting portion 82, and is not rotatable in relation to the second supporting structure 80. Referring to FIG. 5D, when the second gear 90 is in the second free position, the second gear 90 is released from the second limiting portion 82, and is rotatable in relation to the second supporting structure 80.
FIG. 6A and FIG. 6B show the assembly of the first member 10, the elastic element 50, the first slide module and the second slide module. As shown in FIG. 6A, the first member 10 comprises a first hole 11, a second hole 12, a first sliding notch 13 and a second sliding notch 14, and the holes and sliding notches are symmetrical. According to FIG. 6B, when the first slide module is disposed on a first connection portion 15 of the first member 10, the first hole 11 enables a part of the first gear 70 to be exposed thereby and corresponds to the first sliding notch 13. Similarly, when the second slide module is disposed on a second connection portion 16 of the first member 10, the second hole 12 enables a part of the second gear 90 to be exposed thereby and corresponds to the second sliding notch 14. The elastic element 50 can be a torsion spring, and comprises a first end 50A and a second end 50B. The first end 50A is fixed to the first fixing shaft 74 of the first gear 70, and the second end 50B is fixed to the second fixing shaft 94 of the second gear 90. The first fixing shaft 74 and the second fixing shaft 94 have non-circular cross sections (in FIG. 4A and FIG. 4B, for example, the first fixing shaft 74 and the second fixing shaft 94 are square columns), and the both ends 50A and 50B of the elastic element 50 are also non-circular, so the elastic element 50 is fixed between the first gear 70 and the second gear 90 without rotation. Thus, the first gear 70 forms a first rotating structure, the second gear 90 forms a second rotating structure, and both rotating structures are respectively rotatable in relation to the elastic element 50 to generate torque.
FIG. 7 shows the first sliding track 30 and the second sliding track 40. The first sliding track 30 and the second sliding track 40 are parallel on the second member 20 corresponding to the first sliding notch 13 and the second sliding notch 14. The first sliding track 30 comprises a first track section 32 and a second track section 34, and the second sliding track 40 comprises a third track section 42 and a fourth track section 44. The first track section 32 comprises a first rack 36, and the fourth track section 44 comprises a second rack 46.
The action of the torque-retaining assembly, formed by the elastic element 50, the first slide module and the second slide module, is described hereinafter in detail with respect to FIG. 8A and FIG. 8B.
In FIG. 8A, when the second member 20 is between the first position (referring to FIG. 2A) and the central position (referring to FIG. 2B) in relation to the first member 10, the first gear 70 corresponds to the first track section 32 of the first sliding track 30, and the second gear 90 corresponds to the third track section 42 of the second sliding track 40. Since the first track section 32 comprises the first rack 36 and the third track section 42 comprises no rack, the first gear 70 engages the first rack 36, moving the first gear 70 to the first free position, and the second gear 90 is in the second limited position. Thus, the first gear 70 (i.e. the first rotating structure) is rotatable, and the second gear 90 (i.e. the second rotating structure) is not.
Further, in FIG. 8B, when the second member 20 is between the central position (referring to FIG. 2B) and the second position (referring to FIG. 2C) in relation to the first member 10, the first gear 70 corresponds to the second track section 34 of the first sliding track 30, and the second gear 90 corresponds to the fourth track section 44 of the second sliding track 40. Since the fourth track section 44 comprises the second rack 46 and the second track section 34 comprises no rack, the second gear 90 engages the second rack 46, moving the second gear 90 to the second free position, and the first gear 70 is in the first limited position. Thus, the first gear 70 (i.e. the first rotating structure) is not rotatable, and the second gear 90 (i.e. the second rotating structure) is rotatable.
In other words, when the second member 20 is to be moved from the first position as shown in FIG. 2A to the second position as shown in FIG. 2C, the second member 20 is moved from the first position to the central position as shown in FIG. 2B. Since the first gear 70 (i.e. the first rotating structure) is rotatable and the second gear 90 (i.e. the second rotating structure) is not when the second member 20 is between the first position and the central position, the elastic element 50 generates torque. When the second member 20 passes the central position, the first gear 70 (i.e. the first rotating structure) is not rotatable, and the second gear 90 (i.e. the second rotating structure) is rotatable. Thus, the torque generated and stored in the elastic element 50 is released, driving the second gear 90 to rotate and moves the second member 20 from the central position to the second position. Thus, no external force is required.
Similarly, when the second member 20 is to be moved from the second position as shown in FIG. 2C to the first position as shown in FIG. 2A, the second member 20 is moved from the second position to the central position as shown in FIG. 2B. Since the first gear 70 (i.e. the first rotating structure) is not rotatable and the second gear 90 (i.e. the second rotating structure) is rotatable when the second member 20 is between the central position and the second position, the elastic element 50 generates torque. When the second member 20 passes the central position, the first gear 70 (i.e. the first rotating structure) is rotatable, and the second gear 90 (i.e. the second rotating structure) is not rotatable. Thus, the torque generated and stored in the elastic element 50 is released, driving the first gear 70 to rotate and moves the second member 20 from the central position to the first position. Thus, no external force is required.
It should be noted that the first sliding track 30 and the second sliding track 40 in FIG. 7 are individual and separate structures. In another embodiment, however, the first sliding track 30 and the second sliding track 40 can be integrally formed as a rack board 35 as shown in FIG. 9.
Further, in the embodiments disclosed, the first position is a closed position, and the second position is an open position. However, the first and second positions can be any positions, not being limited to the embodiments and the figures.
Further, the torsion direction of the elastic element 50 is not limited and can be clockwise or counterclockwise. A variety of torsion spring structures can be employed as the elastic element 50.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
