The control circuit 3 has an inductive element; specifically, in the present embodiment, the environment or the state of the user at the time of the safety landing apparatus 100 may be sensed by an sensing element, such as the height of the user at the time, the temperature, humidity, or position of the environment, etc., and the sensing element may be various sensors, etc.

The air supply device 2 is communicated with the first air bag through a first control switch, the air supply device 2 is communicated with the second air bag through a second control switch, and the first control switch and the second control switch are electrically connected with the control circuit 3. It can be appreciated that the first air bag and the second air bag can be controlled independently through the first control switch and the second control switch, so that the inflation opening of the first air bag and the second air bag can be flexibly controlled, in particular, the first air bag and the second air bag can have different protective performances or protect different parts of a user, so that the first air bag and/or the second air bag can be selected to be ventilated according to specific use environments to form effective protection, for example, any one air bag of the first air bag and the second air bag can be selected to be ventilated to form primary air bag opening, or the first air bag and the second air bag are ventilated at intervals to form secondary air bag opening, or the first air bag and the second air bag are simultaneously ventilated to be opened to be protected. In this embodiment, the first air bag may include the active air bag parachute 1, and the second air bag may include the trunk protection air bag 5, where the active air bag parachute 1 can support and form resistance to the user in the high-altitude environment in the open state, and the trunk protection air bag 5 can support and buffer the user when the user falls in the low-altitude environment in the open state, and protect the body of the user, so as to reduce the impact force of the user after falling, and enable the user to protect both when falling from the high altitude and the low altitude, and further ensure the safety of the user. Of course, in other embodiments, the first airbag and the second airbag may be other airbags for protecting the user in various environments, and the present invention is not limited thereto.

In summary, the safety landing apparatus 100 is configured to be fixed on a user through the air supply device 2, the first air bag, the second air bag, the control circuit 3, the body 4, the first control switch and the second control switch, so as to assist the user in forming protection in dangerous states such as a high-altitude falling process, where the first air bag and the second air bag can have different protection performances or protect different parts of the user, so that the first air bag and/or the second air bag can be selected to be ventilated according to specific use environments to be opened to form effective protection. Therefore, through the cooperation of the first air bag and the second air bag, the first air bag and/or the second air bag can be correspondingly opened when a user is in different environments, so that the first air bag is opened in ventilation or the second air bag is opened in ventilation at intervals, or the two air bags are opened in ventilation at the same time, so that a protective air bag is formed, and effective protection is formed for the user.

In some embodiments, the gas supply device 2 comprises a first gas cylinder 21 and a second gas cylinder 22; the first gas cylinder 21 communicates with the first gas bag through a first control switch, and the second gas cylinder 22 communicates with the second gas bag through a second control switch. It will be appreciated that depending on the particular environment or user's condition of the safety landing apparatus 100, it may be possible to selectively control the first gas cylinder 21 to communicate with a first gas bladder, such as the active air bladder parachute 1, via a first control switch and to cause the active air bladder parachute 1 to open, and/or to selectively control the second gas cylinder 22 to communicate with a second gas bladder, such as the torso protective air bladder 5, via a second control switch and to cause the torso protective air bladder 5 to open, accordingly. In addition, the first air bag and the second air bag are independently supplied by the first air bottle 21 and the second air bottle 22, so that the opening of the first air bag and the second air bag can be controlled more flexibly and rapidly, and the influence of mutual interference on the opening speed and the effect can be effectively avoided. The number of the first gas cylinders 21 and the second gas cylinders 22 may be set according to actual situations, and may be one or more, and is not particularly limited herein; and the gas stored in the first gas cylinder 21 and the second gas cylinder 22 is inert gas, so that reaction or explosion and the like can be avoided after the inert gas is sprayed out from the high altitude, and the safety performance is improved.

In some embodiments, the first balloon comprises an active balloon parachute 1 and the second balloon comprises a torso protective balloon 5; it should be noted that, the user may sleeve or wear the body 4 during the falling at high altitude or falling at low altitude, as shown in fig. 5, 6, 11 and 12, the active air bag parachute 1 and the trunk protection air bag 5 are both disposed on the body 4; when the safety landing apparatus 100 reaches the first height or the second height, the first gas cylinder 21 communicates with the active airbag parachute 1 through the first control switch and/or the second gas cylinder 22 communicates with the torso-protecting airbag 5 through the second control switch. In this embodiment, the first height is higher than the second height, when the user sleeved with the safety landing device 100 is detected to fall from the high altitude to the first height, the first air bottle 21 can be controlled by the control circuit 3 to be communicated with the active air bag parachute 1, the first air bottle 21 supplies air to the active air bag parachute 1 to enable the active air bag parachute 1 to be opened, and the active air bag parachute 1 supports the user and forms resistance to reduce the falling force of the user, so that the safety of the user is ensured; when the user continues to fall to the position of the second height from the position of the first height, or the user falls to the position of the second height from the low altitude, the second gas cylinder 22 and the trunk protection gas bag 5 can be controlled to be communicated through the control circuit 3, the second gas cylinder 22 supplies gas to the trunk protection gas bag 5 so that the trunk protection gas bag 5 is opened, the trunk protection gas bag 5 supports and buffers the user, the body of the user is protected, the impact force received after the user falls is reduced, and the safety of the user is further guaranteed. Therefore, the active airbag parachute 1 and the trunk protection airbag 5 are matched, so that a user can be protected when falling from different heights. In addition, when the user falls from the high altitude, the user may directly control the active air bag parachute 1 and the trunk protection air bag 5 to be opened simultaneously, or only open the active air bag parachute 1, or open the active air bag parachute 1 first, and then open the trunk protection air bag 5, so that the opening modes of the active air bag parachute 1 and the trunk protection air bag 5 are selected according to different falling environments and conditions, and the method is not particularly limited.

In some embodiments, as shown in fig. 5 to 7, the active air bag parachute 1 includes a connector 11, a canopy 12, and a ventilation bladder 131; the umbrella surface 12 is connected with the body 4 through the connecting piece 11, the air inlet end and the air outlet end of the ventilation bag body 131 are respectively connected with the first air bottle 21 and the umbrella surface 12, and the ventilation bag body 131 is arranged on the umbrella surface 12 along the extending direction of the umbrella surface 12 and/or the ventilation bag body 131 is arranged on the connecting piece 11 along the direction of the connecting piece 11. It can be understood that, when the first air bottle 21 supplies air to the air bag 131, the air bag 131 forms a similar skeleton shape to be supported on the umbrella surface 12 after being inflated when the air bag 131 is arranged along the umbrella surface 12 so as to drive the umbrella surface 12 to be integrally opened, and when the air bag 131 is arranged along the direction of the connecting piece 11, the air bag 131 supports the umbrella surface 12 together with the connecting piece 11 so as to enable the umbrella surface 12 to be opened upwards from the bottom after being inflated, so that the umbrella surface 12 can be opened quickly under the holding of air and high-pressure air sprayed by the air bag 131, thereby improving the opening speed of the umbrella, enabling the umbrella surface 12 to be formed quickly when a user is in a high-altitude environment, and improving the protection effect on the user.

In some embodiments, as shown in fig. 5, the connection member 11 includes a plurality of umbrella strings 111, for example, the umbrella strings 111 may be provided in four, five, six, etc., without being particularly limited thereto. The umbrella cover 12 is connected to the body 4 through the matching of the umbrella ropes 111; the airbag body 131 is provided in plurality, and each airbag body 131 is provided on the umbrella rope 111 along the extending direction of the umbrella rope 111. As can be appreciated, the umbrella strings 111 can be matched to firmly connect the umbrella cover 12 to the body 4, so as to avoid the umbrella cover 12 from being separated from the body 4 after being unfolded to influence the protection effect; through setting up logical gasbag body 131 on the umbrella rope 111, the umbrella rope 111 can form the guide effect to the logical gasbag body 131, can improve logical gasbag body 131 bulge direction's stability to make logical gasbag body 131 can bulge in order along the umbrella rope 111 direction and accurate injection in umbrella face 12, thereby improve injection accuracy.

In some embodiments, as shown in fig. 6, a plurality of ventilation bags 131 are disposed along the edge of the umbrella cover 12 in a dispersed manner, for example, the ventilation bags 131 may be disposed in 2, 3, 4, etc., without being limited thereto, and the air outlet ends of the ventilation bags 131 are flush with the edge of the umbrella cover 12. As can be appreciated, the air passing bag bodies 131 are arranged along the edge of the umbrella surface 12 in a dispersed manner, and the air passing bag bodies 131 can flow upwards along the cambered surface of the umbrella surface 12 at the bottom end of the umbrella surface 12 through the air outlets of the air passing bag bodies 131, so that the air passing bag bodies 131 can be uniformly distributed on the inner side of the whole umbrella surface 12, the swelling speed of the umbrella surface 12 is effectively improved, and the influence on the opening speed and the opening effect of the umbrella surface 12 caused by uneven local inflation can be avoided. Of course, the ventilation bag 131 is not limited to the edge of the canopy 12, and the ventilation bag 131 may be provided at any position inside the canopy 12 where the umbrella string 111 is connected, for example, at a position near the center inside the canopy 12, and is not particularly limited herein. In addition, the case that the air outlet end of the air bag 131 is flush with the edge of the umbrella cover 12 is not limited to the case that the air outlet end of the air bag 131 is at the same height as the edge of the umbrella cover 12, and the case that the air outlet end of the air bag 131 is slightly higher than the edge of the umbrella cover 12 or slightly lower than the edge of the umbrella cover 12 is applicable.

In some embodiments, as shown in fig. 6, the active air bag parachute 1 further includes a stabilizer 14, at least part of the stabilizer 14 has a flexible property, specifically, the stabilizer 14 may have a flexible property in part of the structure, or the whole structure has a flexible property, and it should be noted that the flexible property of the stabilizer 14 enables the stabilizer 14 to be deformed arbitrarily to form an arbitrary shape. In this embodiment, the stabilizer 14 is a rope, and has flexibility as a whole, so that the shape can be arbitrarily changed. The stabilizer 14 is connected with each of the umbrella strings 111 in turn along the circumferential direction of the connector 11 to form a ring structure, and the stabilizer 14 encloses the umbrella strings 111 within the ring structure. It can be appreciated that the stabilizer 14 encloses the umbrella rope 111 in the annular structure, so that the umbrella rope 111 can be effectively prevented from being knotted, wound and the like, and the umbrella cover 12 is prevented from being opened.

In some embodiments, there are at least two stabilizers 14, each stabilizer 14 is disposed on the umbrella rope 111 at intervals along the extending direction of the long end of the connecting member 11, and each stabilizer 14 and each umbrella rope 111 cooperate to form a conical net structure. As can be appreciated, the stabilizer 14 cooperates with the umbrella rope 111 to form a conical net structure, which can improve stability of the umbrella rope 111, maintain stability of the inflation direction of the air bag 131, and further effectively avoid overlapping and winding of the umbrella rope 111, and maintain smoothness of the umbrella rope 111.

In some embodiments, the radial area of the air inlet end of the venting bladder 131 is greater than the radial area of the air outlet end of the venting bladder 131. As can be appreciated, the ventilation bag 131 has a structure with a large air inlet end and a small air outlet end, so that the first air bottle 21 can be intensively ejected from the air outlet end after being supplied to the ventilation bag 131, the inner side of the umbrella cover 12 can be accurately ejected to open the umbrella cover 12, the bulge effect of the ventilation bag 131 can be effectively improved, and the ventilation bag 131 can be quickly bulged to support the umbrella cover 12 and eject the umbrella cover 12.
