Detailed Description
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the invention, and are not intended to limit the scope of the invention.
Referring to fig. 1 and 2, the present invention provides a landing apparatus 100, which can be used to connect a load 4, and the landing apparatus 100 can slowly land under resistance of air flow so that the load 4 can safely land. The carrying object 4 may be an article or a person, or a mixture of a person and an article, for example, the box body is connected with the landing device, and the person is located in the box body. In addition, the parachute can be quickly opened in the releasing process of the landing device 100, the landing device can be quickly fully opened in a short time, the object 4 can not be basically overloaded during landing, and the object 4 can be effectively protected.
Fig. 1 shows a state immediately before the landing gear 100 is released, and fig. 2 shows a state when the landing gear 100 is fully opened.
Referring to fig. 1 and 2, the landing apparatus 100 includes a main umbrella 1, an auxiliary umbrella 2, and a connection rope 3, both ends of the connection rope 3 being connected to the main umbrella 1 and the auxiliary umbrella 2, respectively, so that the main umbrella 1 and the auxiliary umbrella 2 are connected. The main umbrella 1 plays a main role in buffering and bearing, and the auxiliary umbrella 2 is used for assisting the main umbrella 1 to be opened quickly so as to avoid overload of the landing of the carrier 4 caused by the fact that the main umbrella 1 cannot be fully opened before landing. The canopy of auxiliary umbrella 2 is located the inside of main umbrella 1, and parachute device 100 is at the in-process of release, and auxiliary umbrella 2 can shunt the air current that comes in, and the air current after the reposition of redundant personnel can blow the inner wall to main umbrella 1, drives main umbrella 1 and opens fast, and main umbrella 1 can be opened fast in the short time to protect cargo 4 effectively.
The main umbrella 1 comprises a main umbrella cloth 11, a plurality of main ropes 12 and a main rope ring 13, wherein one ends of the main ropes 12 are connected with the main umbrella cloth 11 around the circumference of the main umbrella cloth 11, the other ends of the main ropes 12 are gathered together and are simultaneously connected with one end of the main rope ring 13, and the other ends of the main rope ring 13 are used for being connected with a carrying object 4. When the main canopy 11 is fully opened, the main canopy 11 can receive a large air resistance, and plays a role of buffering the load 4, so that the load 4 can slowly and stably fall.
The end of the main canopy 11 remote from the main rope 12 is provided with one airflow hole 111, and the number of the airflow holes 111 in the embodiment shown in fig. 4 is one, and the airflow hole 111 is located in the middle of the top of the main canopy 11. During landing, the air flows first enter the main canopy 11 and then are blown out through the air flow holes 111. By providing the airflow holes 111, the landing device 100 can have a faster landing speed within a safe range, saving landing time. In addition, the landing device 100 is not substantially affected by the transverse wind force during landing and is greatly deviated from the landing path, which is beneficial to improving the landing stability.
Referring to fig. 5, in other embodiments, the number of air flow holes 111 may be plural, and the number of air flow holes 111 in the embodiment shown in fig. 5 is nine, wherein one air flow hole 111 is located at the center of the top of the main canopy 11, and the other eight air flow holes 111 are uniformly arranged around the circumference of the air flow hole 111. Compared with the previous embodiment, the diameter of the airflow hole 111 in this embodiment can be smaller than that of the airflow hole 111 in the previous embodiment, and the same technical effect as that of the previous embodiment can be achieved. In other embodiments, the plurality of air flow holes 111 are provided in a circular array at a top middle portion of the main canopy 11.
Referring to fig. 3, when the landing gear 100 is not provided with the auxiliary parachute 2, most of the air flow coming from the head-on during the landing of the landing gear 100 is blown out directly through the air flow hole 111, the main canopy 11 may take a long time to be unfolded, and the main canopy 11 may not be fully unfolded when the load 4 reaches the ground, resulting in a great landing overload of the load 4 and excessive damage to the load 4.
Referring to fig. 1, one end of the main rope ring 13 is simultaneously connected to a plurality of main ropes 12, and one end of the main rope ring 13 forms a first knot 131 and is simultaneously connected to a plurality of main ropes 12 through the first knot 131. The other end of the main rope ring 13 is formed with a first connecting hole 132, and the first connecting hole 132 is used for connecting the object 4, for example, the object 4 can be fastened to the first connecting hole 132 through a rope, so that the main rope ring 13 is connected with the object 4 quickly and conveniently.
The first knot 131 is also connected to the connecting rope 3 to be connected to the auxiliary umbrella 2 through the connecting rope 3. In other embodiments, the connecting rope 3 may also be directly connected to the main rope 12, for example, the end of the connecting rope 3 remote from the auxiliary umbrella 2 may be fused with the ends of the main ropes 12 by thermal compression, and then connected to the first knots 131.
In other embodiments, the first knots 131 may be formed by fastening the positions of the plurality of main ropes 12 near the ends using one fastener, and the first connection holes 132 may be formed by braiding the ends of the plurality of main ropes 12, so that the plurality of main ropes 12 may be directly connected to the carrier 4, which is advantageous for improving the stability of connection with the carrier 4.
Referring to fig. 6, fig. 6 shows another embodiment of the main rope loop 13, in which first connection holes 132 are formed at both ends of the main rope loop 13, and a first knot 131 is formed at the middle portion of the main rope loop 13. Both ends of the main rope ring 13 can be used for connecting a plurality of main umbrellas 12 or the carrying object 4, so that the end of the main rope ring 13 is not needed to be considered when the umbrella is used, and the foolproof effect is achieved.
Referring to fig. 7, the auxiliary umbrella 2 includes an auxiliary canopy 21, a plurality of auxiliary ropes 22, and an auxiliary rope ring 23, one ends of the plurality of auxiliary ropes 22 are connected around the circumference of the auxiliary canopy 21, and the other ends of the plurality of auxiliary ropes 22 are connected to the auxiliary rope ring 23. The auxiliary rope loop 23 is connected to the main rope loop 13 or the main rope 12 to connect the auxiliary umbrella 2 with the main umbrella 1. Since the top of the auxiliary canopy 21 is not provided with an airflow hole, the auxiliary canopy 21 is more easily opened and fully opened by the airflow during the release of the parachute device 100, and the auxiliary canopy 21 is also fully opened before the main canopy 11. When the auxiliary umbrella 21 is opened and fully opened, a certain distance exists between the auxiliary umbrella 21 and the inner wall of the main umbrella 11, the auxiliary umbrella 21 can split the oncoming air flow, the air flow after splitting can be obliquely blown to the inner wall of the main umbrella 11, the main umbrella 11 is driven to be opened and fully opened quickly, and the opening time of the main umbrella 11 is shortened.
One end of the auxiliary rope loop 23 forms a second knot 231 and simultaneously connects the plurality of auxiliary umbrella ropes 22 through the second knot 231, and the other end of the auxiliary rope loop 23 forms a second connection hole 232 and is connected to the connection rope 3 through the second connection hole 232 to be connected to the main umbrella 1 through the connection rope 3.
In other embodiments, the auxiliary rope ring 23 may be further configured in the embodiment shown in fig. 6, where the middle is a second knot 231, and two sides are formed with second connection holes 232, so that two ends of the auxiliary rope ring 23 can be connected with the auxiliary umbrella rope 22 or the connection rope 3, and the foolproof effect is achieved.
In other embodiments, the end of the plurality of auxiliary umbrellas 22 remote from the auxiliary canopy 21 may be directly connected to one end of the connecting rope 3, without being connected to the connecting rope 3 by an auxiliary rope loop 23, which is advantageous in reducing the complexity of the structure.
In the unfolded state, the area of the auxiliary umbrella 21 is smaller than that of the main umbrella 11, and the area of the auxiliary umbrella 21 is larger than or equal to that of the air flow holes 111 at the top of the main umbrella 11, so that the air flow split by the auxiliary umbrella 21 is reduced as much as possible and directly passes out of the air flow holes 111, more air flow can be blown to the inner wall of the main umbrella 11, and the main umbrella 11 is driven to be unfolded quickly.
In the deployed state, the central axis of auxiliary canopy 21 and the central axis of main canopy 11 of the embodiment of fig. 1 coincide or nearly coincide, so that the air flow split through auxiliary canopy 21 can be uniformly directed along Zhou Cechui of auxiliary canopy 21 toward the inner wall of main canopy 11.
The reference surface is defined as a plane perpendicular to the height direction of the landing gear 100, and the projection of the auxiliary canopy 21 on the reference surface completely covers the projection of the airflow holes 111 on the reference surface, so that the airflow split by the auxiliary canopy 21 can be blown more toward the inner wall of the main canopy 11.
The number of auxiliary umbrellas 2 is not limited, and may be one or more, and in other embodiments, the number of auxiliary umbrellas 2 may be more than one, and the plurality of auxiliary umbrellas 2 are all located inside the main canopy 11 and connected to each other by the connection rope 3, and the plurality of auxiliary umbrellas 2 are arranged in a straight line along the height direction of the landing device 100. It is also understood that when the landing gear 100 is in a vertical or nearly vertical state during landing, the connection strings 3 are arranged at intervals along the length extension direction of the connection strings 3. The provision of a plurality of auxiliary umbrellas 2 has the advantage that the incoming airflow from the landing gear 100 can be split a number of times so that more airflow is blown against the inner wall of the main canopy 11 after being split, thereby driving the main canopy 11 to unfold rapidly.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
