Hereinafter, embodiments of the present invention will be described with reference to Figs. 1 to 3 . This description is not intended to limit the embodiments of the invention, but is an embodiment of the invention.

As shown in FIG. 1 to FIG. 3, a portable escape descent device 100 according to an embodiment of the present invention includes: a portable carrier 1 including an equipment component 11 and a retaining member 12, the equipment The member 11 is provided to the user carrier U, the retaining member 12 is mounted on the equipment member 11 and has a retaining space 120; a lowering device 2 includes a ring gear 21 and a safety cable 22, The ring gear 21 is rotatably disposed in the enclosing space 120 and has a ring inner space 210. One end of the safety cable 22 is fixed to a support O and the other end is wound around the ring gear 21, so that the ring gear 21 is Rotating with the release of the safety cable 22; and a retarding device 3 disposed in the enclosure space 120 includes a transmission gear set 31 and a power generating mechanism 32, the transmission gear set 31 being located in the ring gear 21 a ring inner space 210 is connected between the ring gear 21 and an input gear 321 of the power generating mechanism 32, and when the ring gear 21 is rotated, the transmission gear set 31 drives the power generating mechanism 32 to generate electricity, and The power generation resistance of the power generation mechanism 32 slows down the input The rotational speed of the gear 321 interlocks to slow the release speed of the safety cable 22.

As shown in FIG. 1 , the portable carrier 1 is the same backpack, the enclosure member 12 is an enclosure, and the equipment component 11 is a strap. The user U picks up the backpack and completes the portable escape descent device 100. And can quickly prepare for the fall of escape. Preferably, the equipment member 11 is a one-meter-shaped strap, which surrounds the body U and the limbs of the user U when equipped, and is tightly combined with the user to avoid falling off. The retaining member 12 is preferably a mesh member having a plurality of venting mesh openings 121 to aid in ventilation to provide good heat dissipation to the internal mechanism.

As shown in FIGS. 2 and 3, the ring gear 21 of the lowering device 2 is disposed in the enclosure space 120 of the retaining member 12. One of the outer ring portions of the ring gear 21 is formed with a winding frame 211 for the safety cable 22 to be wound around the winding frame 211. One of the inner ring portions of the ring gear 21 is formed with a plurality of internal teeth 212 that engage the retarding device 3. One end of the safety cable 22 is wound around the winding frame 211. The other end of the safety cable 22 extends from the retaining member 12 and can be used for bundling or fastening to the support O through other accessories. In actual application, the user U can equip the portable carrier 1 to perform the descending escape as long as the safety cable 22 is fixed.

As shown in FIGS. 2 and 3, the transmission gear set 31 of the retarding device 3 is located in the ring inner space 210 of the ring gear 21. Such an arrangement achieves efficient use of space, thereby reducing the volume of the containment member 12 and even the overall portable escape descent device 100, facilitating the carrying and equipment of the overall device. Preferably, the entire retarding device 3 can be located in the inner space 210 of the ring gear 21 to further save space.

As shown in Figures 2 and 3, the transmission gear set 31 can include a plurality of media gear sets (three media gear sets in this embodiment). The input gear 321 of the power generating mechanism 32 is located at a substantial rotation center of the ring gear 21, and the plurality of medium gear sets are respectively meshed between the input gear 321 and the ring gear 21, thereby transmitting the rotation of the ring gear 21 to The input gear 321 drives the power generating mechanism 32. Moreover, by the arrangement of the plurality of medium gear sets, the input gear 321 is evenly biased by the transmission gear set 31 in a plurality of directions at the same time, thereby making the overall structure more stable and the overall transmission smoother.

Further, in the present embodiment, each of the medium gear sets includes a plurality of gears 311, 312a, 312b. The gear 311 meshes with the internal teeth 212 of the ring gear 21, and the number of teeth of the gear 311 is smaller than the number of teeth of the internal teeth 212 of the ring gear 21. The gear 312a engages the gear 311, and the number of teeth of the gear 312a is smaller than the number of teeth of the gear 311. The gear 312b is a companion gear of the gear 312a. The gear 312b engages the input gear 321, and the number of teeth of the gear 312b is greater than the number of teeth of the gear 312a and greater than the number of teeth of the input gear 321. With such a gear arrangement and a gear design, the transmission gear set 31 serves as an acceleration gear set having an acceleration gear ratio for the transmission of the ring gear 21 to the power generation mechanism 32, and the rotation speed of the ring gear 21 is passed. The transmission of the gears 311, 312a, 312b is gradually amplified, so that the power generating mechanism 32 obtains a higher rotational speed than the ring gear 21.

As shown in FIG. 3, the power generating mechanism 32 includes a power generation load 33. The input gear 321 rotates to drive the power generation mechanism 32 to generate power to the power generation load 33. The power generation mechanism 32 generates a reverse power generation resistance (resistance torque) against the rotation of the power generation mechanism 32, and the value thereof is proportional to the rotation speed of the power generation mechanism 32 and the power generation load 33, and the power generation is slowed down. The rotation of the mechanism 32. Therefore, the power generation resistance of the power generating mechanism 32 is transmitted through the input gear 321 and the transmission gear set 31 to slow down the rotation speed of the ring gear 21, thereby slowing down the release speed of the safety cable 22. Moreover, as the release speed of the safety cable 22 is slowed down, the rotational speed of the power generating mechanism 32 is also reduced, so that the power generation resistance is reduced, and finally the release speed of the safety cable 22 is stabilized, so that the user U can wait for Quickly safely descend to the ground. In addition, as described above, in the embodiment, the transmission gear set 31 is an acceleration gear set, and therefore the rotation speed of the power generation mechanism 32 is higher than that of the ring gear 21, thereby making the power generation resistance larger and allowing the safety. The release rate of cable 22 has a more pronounced slowdown.

As shown in FIG. 3, the power generation load 33 may generally include a resistance line, and the power generated by the power generation mechanism 32 is directed to the resistance line to be converted into thermal energy. Further, in order to prevent the resistance wire from being blown during the operation of the power generating mechanism 32 and losing the load effect, a high melting point resistance wire can be further used. Preferably, the power generation load 33 includes a plurality of complex array resistance wires 331 connected in parallel to each other, so that the risk of melting is reduced by dispersion.

As shown in FIG. 3, the portable escape descent device 100 can also include a blade device 4. The blade device 4 is provided with a power generation load 33 corresponding to the power generation mechanism 32, and is mechanically connected to the power generation mechanism 32 in the present embodiment, and rotates the air supply as the power generation mechanism 32 rotates. Of course, the present invention is not limited thereto. The blade device 4 may also be connected to the ring gear 21 or the transmission gear set 31, and rotate the air supply according to the rotation of the ring gear 21 or the transmission gear set 31 to The power generation load 33 is dissipated so that the temperature of the resistance wire 331 does not rise to the melting point and is burnt.

With the above structure, the user U can individually use a portable escape descent device 100 to escape, without waiting for the same escape device to take turns, but can improve the escape efficiency and relieve the burden of the general shared escape device. Furthermore, the portable escape descent device 100 can automatically adjust the descent speed by utilizing the power generation resistance, thereby giving appropriate deceleration to provide a comfortable and safe slow-escape effect.
