As shown inFIG. 1, the electronic device3000includes a casing1and a rotary flap door device2. The casing1is selectively equipped with a first data storage component3, and the rotary flap door device2is installed inside the casing1. In this embodiment, the electronic device3000is an industrial computer or a server computer, and the first data storage component3is a data storage device, such as a hard disc drive, an optical disc drive and so on, installed inside the electronic device3000(i.e. the industrial computer or the server computer), but the present invention is not limited thereto.

Please refer toFIG. 2andFIG. 3.FIG. 2is a diagram of the rotary flap door device2according to the embodiment of the present invention.FIG. 3is a diagram of the rotary flap door device2in another view according to the embodiment of the present invention. As shown inFIG. 2andFIG. 3, the rotary flap door device2includes a base plate20and three door members21. The base plate20is mounted on the casing1. Each of the door members21includes a door body210, a door limit part211, a door engaging portion212and two pivotal arms213, and the base plate20includes a pivotal axis203, which is located in a position corresponding to the pivotal arm213. Furthermore, a base limit part201and a base engaging portion202are formed on the base plate20, and the pivotal axis203extends from the door body210and is pivoted to the pivotal axis203, such that the door body210is rotably disposed on the base plate20and is capable of rotating to an open position (as shown inFIG. 2andFIG. 3, the door member21located in the top position) or to a closed position (as shown inFIG. 2andFIG. 3, the door members21located in the middle position and the bottom position) relative to the base plate20.

Furthermore, the door limit part211extends from the door body210. In this embodiment, the base limit part201is a constraining hole, the door limit part211is a constraining protrusion, and the constraining protrusion (i.e. the door limit part211) is detachably embedded in the constraining hole (i.e. the base limit part201) . When the door body210rotates to the open position relative, the door limit part211is embedded in the base limit part201on the base plate20, so as to fix the door body210in the open position. As shown inFIG. 1toFIG. 3, an escaping breach204is further formed on the base plate20and located near the pivotal axis203. When the door body210rotates relative to the base plate20, the pivotal arm213of the door member21is rotated with the door body210relative to the pivotal axis203of the base plate20, meanwhile, the escaping breach204provides an escaping space that allows the pivotal arm213to pivot relative to the pivotal axis203, so as to prevent the pivotal arm213from interfering with the base plate20as the pivotal arm213pivots relative to the pivotal axis203.

Furthermore, the base plate20further includes an opening205and a passage206connected with the opening205and the constraining hole (i.e. the base limit part201). A projection area of the passage206is smaller than a projection area of the opening205and a projection area of the constraining hole. In other words, the constraining hole and the opening205are located on two ends of the passage206, and both of sizes of the constraining hole and the opening205are greater than a size of the passage206, such that a constraining block207is formed between the opening205and the constraining hole on the base plate20. When the constraining protrusion (i.e. the door limit part211) is embedded in the constraining hole (i.e. the base limit part201), the constraining block207is used for constraining the constraining protrusion in the constraining hole, so as to fix the door member21in the open position.

In this embodiment, the pivotal arm213and the door limit part211are located on the same side of the door body210, and the pivotal arm213of the door member21is near the door limit part211. Accordingly, the escaping breach204for providing the pivotal arm213with the escaping space as rotation can be near the constraining hole (i.e. the base limit part201) for constraining the door limit part211. In such a manner, a resilient portion208is formed between the escaping breach204and the constraining hole for allowing the constraining block207to deform, such that the constraining block207deforms when the door limit part211embeds in the constraining hole smoothly.

As shown inFIG. 1toFIG. 3, the door engaging portion212protrudes from the door body210. In this embodiment, the base engaging portion202is an engaging hole, the door engaging portion212is an engaging post, and the engaging post (i .e. the door engaging portion212) inserts into the engaging hole (i.e. the base engaging portion202). When the door body210rotates to the closed position relative to the base plate20, the door engaging portion212engages with the base engaging portion202, so as to fix the door body210in the closed position, meanwhile, the door body210overlays on the base plate20. Please refer toFIG. 1andFIG. 4.FIG. 4is a diagram of the rotary flap door device2adapted to a second data storage component4according to the embodiment of the present invention. The main difference betweenFIG. 1andFIG. 4is that the casing1inFIG. 1is equipped with the first data storage component3having a first length L1, while the casing1inFIG. 4is equipped with the second data storage component4inFIG. 4having a second length L2, wherein the second length L2 is greater than the first length L1. In other words, the casing1of the present invention can be selectively equipped with the first data storage component3and the second data storage component4with different sizes.

As shown inFIG. 1, when the casing1is equipped with the first data storage component3with the first length L1, the door body210is rotated to the open position, meanwhile, the door limit part211is embedded in the base limit part201on the base plate20, so as to fix the door body210in the open position. As a result, the door body210and the first data storage component3are capable of cooperatively defining a flow channel10inside the casing1, and the door body210is used for masking a space11on the back side of the first data storage component3, such that the space11does not communicate with the flow channel10. Accordingly, a heat dissipating flow generated by a thermal fan (not shown in figures) is capable of flowing through the inner side of the casing1via the flow channel10. In other words, when the casing1is equipped with the first data storage component3with the first length L1, the door body210is to be fixed in the open position, such that the heat dissipating flow is concentrated to flow through the inner side of the casing1via the flow channel10, so as to prevent from a turbulent flow resulting from the heat dissipating flow diverges to the space11on the back side of the first data storage component3, and further to enhance heat dissipating efficiency of the electronic device3000.

As shown inFIG. 4, when the casing1is equipped with the second data storage component4with the second length L2, the door body210is rotated to the closed position, meanwhile, the door engaging portion212engages with the base engaging portion202, so as to fix the door body210in the closed position and to overlay the door body210on the base plate20. As a result, the door body210does not interfere with the second data storage component4and the second data storage component4is adjacent to the door body210, such that the heat dissipating flow generated by the thermal fan is capable of flowing through the inner side of the casing1via a lateral wall of the second data storage component4. In other words, when the casing1is equipped with the second data storage component4with the second length L2, the door body210is to be fixed in the closed position, such that the heat dissipating is concentrated to flow through the inner side of the casing1via the lateral wall of the second data storage component4, so as to prevent from the turbulent flow resulting from the heat dissipating flow, and further to enhance heat dissipating efficiency of the electronic device3000.

It should be noticed that the door body210has a first side S1and a second side S2opposite to the first side Si. The pivotal arm213and the door limit part211protrude from the first side S1of the door body210, and the door engaging portion212is near the second side S2of the door body210. A taking breach209is formed on the base plate20and located corresponding to the second side S2. The second side S2of the door body210is exposed via the taking breach209. Accordingly, when the door body210is fixed in the closed position, i.e. when the door body210overlays on the base plate20, the second side S2of the door body210can be touched via the taking breach209for facilitating the door body210to be moved from the closed position, such that the door member21is capable of being rotated from the closed position to the open position relative to the base plate20.

In addition, disposals of the rotary flap door device2and the data storage component are not limited to those illustrated in figures in this embodiment. For example, please refer toFIG. 5andFIG. 6.FIG. 5andFIG. 6are respectively diagrams of the rotary flap door device2and the data storage components according to another embodiment of the present invention. As shown inFIG. 5, the rotary flap door device2is adapted for the casing1equipped with two second data storage components4and one first data storage component3. As shown inFIG. 6, the rotary flap door device2is adapted for the casing1equipped with only one second data storage component4. In other words, disposals of the rotary flap door device2and the data storage component depend on practical demands. Components with denoted in this embodiment identical to those in the aforesaid embodiment have identical structures and functions, and further description is omitted herein for simplicity.

When the casing is equipped with the second data storage component with the second length, the door body is rotated to the closed position, meanwhile, the door engaging portion engages with the base engaging portion, so as to fix the door body in the closed position and to overlay the door body on the base plate.
