For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] See also Figures 1 to 6 The utility model discloses a high-altitude transportation safety delivery box, including a delivery box body, the delivery box body includes a box body 1 and a sensing control component 3, a parachute component 2, a sound and light warning component 4 and a power supply component 5 arranged in the box body 1, the box body 1 includes a storage bin 12 and a storage bin 11 for storing items, the parachute component 2 is fixed in the storage bin 12, and an opening 14 is arranged on the box body 1 facing the storage bin 12, the sensing control component 3 is connected to the parachute component 2 and the sound and light warning component 4, and the power supply component 5 is electrically connected to the sensing control component 3 and the parachute component 2. Figure 5 As shown, in normal operation, the parachute assembly 2, the inductive control assembly 3, and the sound and light warning assembly 4 in this embodiment are not working, and the box body 1 is only used as a delivery box, and the user can place items that do not exceed the volume and maximum load requirements of the storage bin 11. In a further embodiment, the parachute assembly 2 includes a compressed parachute 21, a firing mechanism 22, an ejection mechanism 23, and an umbrella cover 24, the umbrella cover 24 is arranged in the parachute opening 14, the bottom of the compressed parachute 21 is provided with a firing mechanism 22, the ejection mechanism 23 is connected to the umbrella cover 24, and the ejection mechanism 23 is electrically connected to the inductive control assembly 3, so that the umbrella cover 24 and the compressed parachute 21 are ejected.

[0029] Specifically, Figure 3 and Figure 4As shown, the parachute assembly 2 includes a compressed parachute 21, a firing mechanism 22, an ejection mechanism 23 and an umbrella cover 24. The umbrella cover 24 is arranged in the opening port 14. The bottom of the compressed parachute 21 is provided with a firing mechanism 22. The ejection mechanism 23 is connected to the umbrella cover 24. The ejection mechanism 23 is electrically connected to the induction control component 3 so that the umbrella cover 24 and the compressed parachute 21 are ejected. In this embodiment, preferably, the firing mechanism 22 is configured as a compression spring group storing elastic potential energy and a firing base. The firing mechanism 22 can also be an ejection mechanism 23 configured as an electromagnet hook 142. A mounting hole is provided in the opening port 14. The electromagnet hook 142 is fixed to the bottom of the mounting hole. A cover leg 241 is provided at the bottom of the umbrella cover 24 corresponding to the mounting hole. The cover leg 241 is inserted into the mounting hole and fixed by the electromagnet hook 142. After the parachute is placed, its cover leg 241 is inserted through the mounting hole on the top of the box body 1. After being fully inserted, it is just located at the grabbing point of the electromagnet hook 142. The electromagnet hook 142 moves and closes, tightly grabs the umbrella cover 24, and closes. At this time, the compressed parachute 21 is stored. It can be understood that the compressed parachute 21 is compressed by the umbrella cover 24 and is set in the storage bin 12. When the umbrella cover 24 pops out, the opening opening 14 above the compressed parachute 21 opens, and the compressed parachute 21 pops out from the opening opening 14 under the action of the firing mechanism 22. The sensing control component 3 includes one or more of an altitude sensor 31, an acceleration sensor 32, and a position sensor. Among them, the altitude sensor 31 has a built-in piezoceramic capacitor, which can calculate the change of its altitude through the change of air pressure; the acceleration sensor 32 has a built-in piezoceramic capacitor, which can sense the change of speed through the inertial movement of the capacitor and read the acceleration; the position sensor can locate the position of the delivery box in real time, so that the dispatch center can locate the delivery box body on the electronic map to find the delivery box. Furthermore, the sensing control component 3 also includes built-in numerical control chips, electrical signal generators, timers and other components to achieve logical judgment, and to actuate the electromagnet hook 142 according to the signal from the sensor. Since the voltage and power required by the sensing control component 3 are relatively small, it is understandable that the power supply component 5 also includes a button battery pack 52 disposed in the storage bin 12, which supplies power to the numerical control chip and sensor in the sensing control component 3. The power of the button battery pack 52 is sufficient for the sensing and control functions of the present invention to operate for more than one year, and the management personnel replace it every year to ensure a stable power supply.

[0030] like Figure 3 and Figure 4As shown, the box 1 is divided into a storage bin 12 and a storage bin 11 from top to bottom by partitions, the bottom of the storage bin 11 is divided into a counterweight bin 13, and the power supply assembly 5 is arranged in the storage bin 12 and / or the counterweight bin 13. By making the overall layout of the box 1 reasonably distributed with counterweights, the box 1 is evenly arranged around the vertical direction, and the weight of the storage bin 11 and the counterweight bin 13 on the lower side is greater than that of the storage bin 12 on the upper side, so that the box 1 is light on the top and heavy on the bottom. When the delivery box falls and free falls, it can be quickly adjusted to a straight up and down posture, and the parachute assembly 2 on the top of the box 1 can be smoothly opened without entanglement, further ensuring that the falling speed of the box 1 is slowed down.

[0031] In a further embodiment, the box body 1 includes an upper shell and a lower shell, the upper shell and the lower shell are hinged to each other, and an opening and closing lock 15 or an electronic lock is provided between the upper shell and the lower shell.

[0032] The counterweight bin 13 is filled with flame retardant material 16, and the counterweight bin 13 is also provided with one or more of a power supply assembly 5, a pressure sensor, and an identity authentication module. The pressure sensor is electrically connected to the induction control assembly 3, and the identity authentication module is connected to the electronic lock. The power supply assembly 5 is configured as a button battery pack 52 and a rechargeable lithium battery 51. The flame retardant material 16 in the counterweight bin 13 plays a buffering and flame retardant effect at the same time, ensuring that the power supply assembly 5 will not burn after falling, and even if it burns, it can avoid burning the entire box 1. The pressure sensor is set at the bottom of the storage bin 11 to read whether there is an additional load in the box 1, determine whether the customer has taken out the items, and facilitate background statistics and scheduling. The identity authentication module can be linked with the electronic lock, read the user information through the NFC function, and determine whether the user has the authority to open the storage bin 11. If the user has the authority, the box will be punched after the card is read, otherwise it will not be opened. To improve the safety and privacy of transported items.

[0033] In a further embodiment, the sound and light warning component 4 includes a buzzer 41 and an LED warning light 42, which are embedded and installed at the bottom of the box body 1. The buzzer 41 and the LED warning light 42 can receive the trigger signal sent by the induction control component 3, and both are powered by the rechargeable lithium battery 51. The buzzer 41 can emit a sharp whistling sound, and the LED warning light 42 flashes a red warning light, which effectively reminds pedestrians below that the delivery box has fallen.

[0034] In a further embodiment, the box 1 is square and the outer corners are all arc chamfered structures. The box 1 is made of fireproof foam material. The fireproof foam material has flame retardant and light properties, making the box 1 more flexible. The arc chamfered structure outside the box 1 further prevents the box 1 from causing harm to pedestrians below when it falls.

[0035] It is understandable that, in order to facilitate the drone to grab the delivery box, a grabbing buckle 17 is also provided on the box body 1 for connecting the drone.

[0036] Implementation Method 1

[0037] like Figure 5 As shown, when a special situation occurs during high-altitude transportation, the connection between the drone and the delivery box is interrupted, and the delivery box falls accidentally. At this time, the delivery box body enters an emergency state of free fall, and the altitude sensor 31 senses the rapid decrease in altitude. When the altitude or the descending altitude exceeds a certain threshold, a "falling" signal is sent to the CNC chip; at the same time, the acceleration sensor will sense that its falling acceleration quickly increases to G, and a "free fall" signal is sent to the CNC chip.

[0038] When the CNC chip receives the "fall" or "free fall" signal, the timer starts working. When the signal lasts for more than 1 second, the CNC chip determines that it has entered an emergency state and executes the output action of the parachute opening signal and the alarm signal. The CNC chip generates current to pass through the electromagnet hook 142, causing it to disengage. At the same time, the power-on command is transmitted to the buzzer 41 and the LED warning light 42.

[0039] When the electromagnet hook 142 is disengaged, the umbrella cover 24 is not subjected to force and quickly pops out and detaches, the firing mechanism 22 loses its suppression, and the elastic potential energy is converted into kinetic energy, the compressed parachute 21 in the compressed state is ejected, and the aerodynamic force in the falling process is used to make the compressed parachute 21 unfold within 0.5s and turn to the parachute opening braking state, and the overall falling speed will be reduced to below 3m / s.

[0040] When the buzzer 41 and the LED warning light 42 receive the power-on command, they are powered by the rechargeable lithium battery 51, the buzzer 41 starts to emit a sharp whistling sound, and the LED warning light 42 flashes a red warning light. The purpose is to alert pedestrians in the falling area through sound and light signals, attracting them to look up and discover the danger. Due to the braking of the compressed parachute 21, the delivery box body falls slowly in this state, and people have sufficient reaction time to dodge and avoid being directly hit by falling objects.

[0041] After the delivery box falls to the ground, the sound and light alarm system is still working, so it is convenient for the management personnel to rush over following the sound. After finding the delivery box, they will remove the battery, stop the alarm system, and take it back to other places for proper disposal.

[0042] The utility model divides the box body 1 into a receiving compartment 12 and a storage compartment 11. Under normal working conditions, the goods to be transported can be placed in the storage compartment 11. When the connection between the delivery box and the drone is disconnected and the box falls during drone transportation, the sensing control component 3 in the receiving compartment 12 senses the state of the delivery box body to identify that the delivery box body has fallen. The sensing control component 3 simultaneously sends a signal to the parachute component 2 and the sound and light warning component 4. The parachute on the box body 1 opens to slow down the falling speed of the delivery box body. At the same time, the sound and light warning component 4 sends a sound and a bright light to warn pedestrians below, thereby further ensuring safety during high-altitude transportation.

[0043] The beneficial effects of the present invention are as follows:

[0044] (1) Created an active protection system for falling from high altitude, reducing the damage caused by the delivery box falling off and the risk of drone delivery;

[0045] (2) Simple structure, reusable, and cost-controllable;

[0046] (3) Good integrity and high compatibility with existing drones;

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
