Detailed ways

Please refer to FIG. 2 first. The semi-automatic sliding mechanism according to an embodiment of the present invention is set in an electronic device, for example, can be used to connect the input module 100 and the display module 200 shown in FIG. 1 . The aforementioned semi-automatic sliding mechanism mainly includes a first member P1, a second member P2, a first rack R1, a second rack R2, a gear G1 and a clockwork spring S, wherein the first and second members P1 , P2 can slide each other. As shown in Figure 2, the aforementioned first and second racks R1 and R2 are fixed on the first member P1, and the gear G1 is pivotally connected to the second member P2, and can be connected between the first and second racks R1 and R2. Rolling up, wherein the first and second racks R1 and R2 are respectively arranged on opposite sides of the gear G1 and parallel to each other, thereby stably guiding the first member P1 to slide relative to the second member P2. It should be noted that another set of gears G2 and third and fourth racks R3 and R4 can be additionally added to the first and second components P1 and P2, and their positions are symmetrical to those of the aforementioned gear G1 and the first and first gear racks. The second racks R1 and R2 can thus improve the stability of the sliding mechanism.

Please continue to refer to FIG. 2, the aforementioned clockwork spring S is accommodated in a groove P21 on the second member P2, wherein the first end S1 inside the clockwork spring S is fixed on the gear G1, and the first end S1 outside the clockwork spring S is The two ends S2 are fixed on the sidewall of the groove P21. When the gear G1 rotates in a specific direction, the clockwork spring S is curled to accumulate an elastic potential energy, and then the elastic potential energy can be released to achieve the purpose of semi-automatic sliding.

Please refer to FIG. 3A and FIG. 3B together. When the first component P1 is at an initial position relative to the second component P2, the first and second components P1 and P2 overlap each other and present a closed state. At this time, the gear G1 and the second component A rack R1 is engaged, and the gear G1 is separated from the second rack R2 (as shown in FIG. 3B ). Next, please refer to Fig. 4A and Fig. 4B together. When the first member P1 is subjected to an external force and slides from the initial position to the first position relative to the second member P2, the gear G1 will be driven by the first rack R1 to rotate Rotate in a first direction D1, and at this time, the clockwork spring S connected to the gear G1 will be curled with the rotation of the gear G1, thereby accumulating an elastic potential energy.

It should be noted that when the first member P1 slides to the aforementioned first position, the gear G1 is separated from the first rack R1 and will mesh with the second rack R2 on the other side. When the aforementioned external force is released, the clockwork spring S will immediately act an elastic force on the gear G1, so that the gear G1 rotates around a second direction D2 and rolls along the second rack R2 (as shown in FIG. 4C ), thereby automatically The pulling first member P1 further slides relative to the second member P2 from the first position to a second position (as shown in FIG. 5A and FIG. 5B ), wherein the second direction D2 is opposite to the first direction D1.

It can be seen from Figures 5A and 5B that when the first member P1 slides beyond the first position and the aforementioned external force is released, the clockwork spring S can release its accumulated elastic potential energy to drive the gear G1 around the first position. The two directions D2 rotate, and since the gear G1 has disengaged from the first rack R1 and meshed with the second rack R2 at this time, the rotation of the gear G1 can pull the first member P1 to slide to the second position relative to the second member P2 ( As shown in FIG. 5B ), the first and second members P1 and P2 can be automatically switched to an open state.

Referring to FIG. 6 again, the first rack R1 of this embodiment mainly includes a first body R10 and a first one-way tooth R12, wherein a first tooth-shaped portion arranged in a straight line is formed on one side of the first body R10 R11, the aforementioned first one-way tooth R12 is set at one end of the first rack R1, and is movably connected with the first body R10 through a first wire spring W1; correspondingly, the aforementioned second rack R2 is mainly It includes a second body R20 and a second one-way tooth R22, wherein a second tooth-shaped portion R21 arranged in a straight line is formed on one side of the second body R20, and the second one-way tooth R22 is set on the second tooth One end of the bar R2 is movably connected with the second body R20 through a second wire spring W2. It should be understood that by arranging the first and second unidirectional teeth R12 and R22 at the ends of the first and second racks R1 and R2, it can be ensured that the gear G1 is stably positioned between the first and second racks R1 and R2. Rolling switch between gears can avoid the idling phenomenon of gear G1 at the same time, which is used to improve the stability of the sliding mechanism.

To sum up, the present invention provides a semi-automatic sliding mechanism, which can be installed in a slide-type electronic device to achieve a semi-automatic sliding function. For example, the aforementioned first and second components P1 and P2 can be selectively fixed on the input module 100 or the display module 200 shown in FIG. Function. Since the present invention uses a clockwork spring to provide the elastic force required by the sliding mechanism, it has the advantages of small size and convenient assembly compared with the traditional sliding mechanism. , can greatly improve the stability of the sliding mechanism.

Although the present invention has been disclosed in combination with the foregoing embodiments, they are not intended to limit the present invention. Those skilled in the art to which the present invention belongs 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.
