Referring toFIG.1throughFIG.6B, an engaging driving structure1of the present disclosure comprises a first driving fastener11, a second driving fastener12and a linking unit13.

The second driving fastener12is parallel to the first driving fastener11.

The linking unit13is perpendicular to both the first driving fastener11and the second driving fastener12and is disposed therebetween. The linking unit13movably connects the first driving fastener11and the second driving fastener12.

The process of assembling the engaging driving structure1involves movably attaching a first object10to an axle portion102of the first driving fastener11and an axle portion102of the second driving fastener12. The axle portions102are fixed to the first object10, adapted to allow the first driving fastener11and the second driving fastener12to rotate at fixed positions, adapted to allow the first driving fastener11to drive the linking unit13and the second driving fastener12under a lever force, and adapted to exert lever forces on a second object20, thereby allowing the first object10and the second object20to undergo displacement relative to each other.

At the beginning of the process of use of the engaging driving structure1, the second driving fastener12is engaged with a second object20, and the first driving fastener11is engaged with the first object10, allowing the engaging driving structure1to fit the first object10and the second object20together. To separate the second object20from the first object10, the user exerts a force to move the first driving fastener11to not only disengage the first driving fastener11from the first object10but also link the first driving fastener11and the second driving fastener12through the linking unit13, either allowing the second driving fastener12to drive the second object20or allowing the second driving fastener12to drive the second object20before disengaging the second driving fastener12from the second object20. Therefore, the first driving fastener11, the second driving fastener12and the linking unit13operate in conjunction with each other so that the engaging driving structure1is easy to use, labor-saving, and convenient.

The axle portions102are fixed to the first object10and adapted to allow the first driving fastener11and the second driving fastener12to rotate at fixed positions, adapted to allow the first driving fastener11to drive the linking unit13and the second driving fastener12under a lever force, and adapted to exert lever forces on the second object20, thereby allowing the first object10and the second object20to undergo displacement relative to each other. Therefore, the first driving fastener11, the second driving fastener12and the linking unit13operate in conjunction with each other to thereby effectuate engagement and/or disengagement, so as to render the engaging driving structure1easy to use, labor-saving, and convenient.

In an embodiment of the present disclosure, the first driving fastener11comprises a first engaging portion111, an operating portion112, a first fitting portion114and a second fitting portion115. The first engaging portion111is disposed at one end of the operating portion112. One end of the linking unit13movably connects to the second fitting portion115.

To mount the first driving fastener11in place, the first fitting portion114is movably fitted to the first object10through the axle portion102. To start using the engaging driving structure1, the second driving fastener12is engaged with a second object20, and the first engaging portion111of the first driving fastener11is engaged with a clasping portion101of the first object10, thereby fitting the first object10and the second object20together by the engaging driving structure1. To separate the second object20from the first object10, the user exerts a force to move the operating portion112of the first driving fastener11to not only disengage the first engaging portion111from the clasping portion101of the first object10but also link the operating portion112of the first driving fastener11and the second driving fastener12through the linking unit13, either allowing the second driving fastener12to drive the second object20or allowing the second driving fastener12to drive the second object20before disengaging the second driving fastener12from the second object20. Therefore, the first driving fastener11, the second driving fastener12and the linking unit13operate in conjunction with each other so that the engaging driving structure1is easy to use, labor-saving, and convenient.

In an embodiment of the present disclosure, the first engaging portion111has a first engaging member1111. The first engaging member1111is fitted to the operating portion112through a pivotal connection member1112. A resilient component1113is disposed between the first engaging member1111and the operating portion112. Therefore, when the first engaging portion111is engaged with the clasping portion101of the first object10, or when the first engaging portion111is disengaged from the clasping portion101of the first object10, collaboration between the first engaging member1111and the pivotal connection member1112enables the first engaging member1111to undergo engagement or disengagement, whereas the resilient component1113enables the first engaging member1111to undergo engagement or disengagement and the ensuing automatic restoration to facilitate the next instance of use, so as to render the engaging driving structure1easy to use, labor-saving, and convenient.

In an embodiment of the present disclosure, the second driving fastener12comprises a second engaging portion121, a third fitting portion122and a fourth fitting portion123. The second engaging portion121is disposed at one end of the second driving fastener12. The third fitting portion122is disposed beside the second engaging portion121. The fourth fitting portion123is disposed beside the third fitting portion122. The other end of the linking unit13movably connects to the fourth fitting portion123.

The assembly process involves movably fitting the first fitting portion114of the first driving fastener11to the first object10through the axle portion102and movably fitting the third fitting portion122of the second driving fastener12to the first object10through the axle portion102. To start using the engaging driving structure, the second engaging portion121of the second driving fastener12is engaged with the second object20, and the first engaging member1111of the first engaging portion111of the first driving fastener11is engaged with the clasping portion101of the first object10, so as for the engaging driving structure1to fit the first object10and the second object20together. To separate the second object20from the first object10, the user exerts a force on the operating portion112of the first driving fastener11to move it and thereby disengage the first engaging member1111of the first engaging portion111from the clasping portion101of the first object10, allow the operating portion112of the first driving fastener11to link to the second driving fastener12through the linking unit13, allow the second engaging portion121of the second driving fastener12to drive the movement of the second object20, or allow the second engaging portion121of the second driving fastener12to drive the movement of the second object20before disengaging the second driving fastener12from the second object20. Therefore, the first driving fastener11, the second driving fastener12and the linking unit13operate in conjunction with each other so that the engaging driving structure1is easy to use, labor-saving, and convenient.

In an embodiment of the present disclosure, a first connection portion131is disposed at one end of the linking unit13, and a second connection portion132is disposed at the other end of the linking unit13. The first connection portion131movably connects to the second fitting portion115of the first driving fastener11through a first axle portion133. The second connection portion132movably connects to the fourth fitting portion123of the second driving fastener12through a second axle portion134.

Therefore, the operating portion112of the first driving fastener11is linked to the second driving fastener12through the linking unit13, whereas collaboration between the first connection portion131, the first axle portion133, the second connection portion132and the second axle portion134is conducive to linking the first driving fastener11and the second driving fastener12to thereby effectuate engagement and/or disengagement, so as to render the engaging driving structure1easy to use, labor-saving, and convenient.

In an embodiment of the present disclosure, the first axle portion133and the second axle portion134each penetrate a washer135. Alternatively, the first axle portion133or the second axle portion134penetrates a washer135. The washer135is disposed between the linking unit13and the first driving fastener11or the second driving fastener12. The washer135enables the linking unit13in operation to attain satisfactory resistance and be abrasive-resistant.

Referring toFIG.7throughFIG.10, the present disclosure provides an engaging driving structure1. The engaging driving structure1is disposed on a first object10and adapted to abut against a second object20. The engaging driving structure1comprises a first driving fastener11, a second driving fastener12and a linking unit13. The first driving fastener11is movably fitted to the first object10. The second driving fastener12is movably fitted to the first object10and adapted to abut against the second object20. The linking unit13is movably fitted between the first driving fastener11and the second driving fastener12. The first driving fastener11is operated and linked to the second driving fastener12to cause movement thereof, so as for the second driving fastener12to abut against the second object20.

As mentioned above, the engaging driving structure1of the present disclosure has advantageous technical features described below. The first driving fastener11is pulled to drive the movement of the second driving fastener12through the linking unit13. The force exerted by the user to pull the first driving fastener11is much less than the thrust generated by the second driving fastener12to push the second object20. Thus, the user just needs to apply a slight force in order to generate an enormous thrust. Therefore, the engaging driving structure1of the present disclosure is labor-saving.

Referring toFIG.7andFIG.10, in an embodiment, the terminal end of the first driving fastener11is movably fitted to an engaging member1111. The first object10comprises a clasping portion101corresponding in position to the engaging member1111. The engaging member1111is engaged with the clasping portion101, such that the second driving fastener12and the second object20abut against each other until they are positioned in place. Preferably, the clasping portion101is a flange which extends outward from a side of the first object10, and the side of the first object10is positioned distal to the second object20. The engaging member1111is movably fitted in place, for example, by pivotally connecting the pivotal connection member1112to a hook of the first driving fastener11. However, the present disclosure is not limited thereto.

Referring toFIG.7throughFIG.10, in an embodiment, the first driving fastener11pivotally connects to the first object10, the second driving fastener12to the first object10, and the linking unit13to the first driving fastener11and the second driving fastener12. The first driving fastener11comprises a movable fitting portion116movably fitted to the first object10and the linking unit13, an operating portion112parallel to the movable fitting portion116, and a connection portion117connected between the movable fitting portion116and the operating portion112. The second driving fastener12comprises a movable fitting body124and an abutting portion125connected to the movable fitting body124. The movable fitting body124is movably fitted to the first object10and the linking unit13. The abutting portion125has a dent portion126for receiving a flange201of the second object20. However, the present disclosure is not limited thereto. The linking unit13is a connecting rod. The two terminal ends of the linking unit13are movably fitted to the first driving fastener11and the second driving fastener12, respectively. Preferably, in this embodiment, the engaging driving structure1further comprises a first pivot50, a second pivot60, a third pivot70and a fourth pivot80. The first pivot50and the first fitting portion114allow the first driving fastener11to pivotally connect to the first object10. The third pivot70and the second fitting portion115allow the first driving fastener11to pivotally connect to the linking unit13. The second pivot60and the third fitting portion122allow the second driving fastener12to pivotally connect to the first object10. The fourth pivot80and the fourth fitting portion123allow the second driving fastener12to pivotally connect to the linking unit13. The third pivot70pivotally connects the linking unit13to the first driving fastener11. The fourth pivot pivotally connects the linking unit13to the second driving fastener12. Referring toFIG.8, the first pivot50, the second pivot60, the third pivot70and the fourth pivot80are arranged to form a rectangle, not only allowing the engaging member1111to engage with the clasping portion101, but also allowing the second driving fastener12and the second object20to abut against each other until they are positioned in place. Alternatively, the first pivot50, the second pivot60, the third pivot70and the fourth pivot80are arranged to form a parallelogram, exclusive of a rectangle, and thereby allow the engaging member1111to separate from the clasping portion101, with the second driving fastener12abutting against the second object20.

Referring toFIG.7andFIG.8, an abutting-oriented acted point E1 is located between the second driving fastener12and the second object20. The acted point E1 is spaced apart from the first pivot50and the second pivot60by a distance D1. The distance between the first pivot50and the third pivot70is denoted by D2. The distance between the second pivot60and the fourth pivot80is denoted by D2. The first driving fastener11has an acting point E2. The acting point E2 is spaced apart from the first pivot50and the second pivot60by a distance D3, where 0.08<D1/D3<0.12, 0.15<D2/(D3−D2)<0.3. The composite abutting force of the acted point E1 is denoted by F1, and the applied force of the acting point E2 is denoted by F2. According to the principle of torque, applied force F2 and abutting force F1 satisfy the relation: 0.012≤F1/F2≤0.036. Thus, the applied force F2 required by the acting point E2 is much less than the abutting force F1 generated by the acted point E1.

Referring toFIG.7, the first object10is a frame back plate, whereas the second object20is a target device, such as a hard disk drive, expansion card, and circuit board. However, the present disclosure is not limited thereto.
