Description

Technical Field

[0001] The present invention relates to a mobile port for landing a mobile body at a location where there is nothing around it and preventing lightweight luggage from being flung (scattered) outside the landing surface when the mobile body departs, and a method for preventing luggage from falling.

Background Art

[0002] The "mobile body" is a vehicle that moves remotely or autonomously, an automated guided vehicle, or a drone (a type of small unmanned helicopter). The "mobile port" means a facility having a landing surface where the mobile body lands and departs.

[0003] In recent years, drones have attracted attention as a new means of delivery in the logistics industry. Also, a drone port where a drone lands and departs is disclosed in, for example, Patent Document 1.

[0004] The "landing site and its fence part" of Patent Document 1 includes a fence part installed around the landing point of a rotary-wing aircraft. The rotary-wing aircraft is an unmanned rotary-wing aircraft that can be operated from outside the aircraft. The fence part has a windbreak part that inhibits the inflow of wind into the landing point and a ventilation part through which wind can pass more easily than the windbreak part. The ventilation part is provided under the windbreak part, and the windbreak part has a window part in which a part of its wall surface is cut off or a perspective part made of a light-transmissive material.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The invention described in Patent Document 1 is a configuration for taking off and landing a drone (mobile body) inside a fence. However, this method carries the risk of the mobile body crashing into the fence upon arrival. Therefore, it is ideal for the mobile body to take off and land in an area with nothing around it. On the other hand, with mobile delivery, a problem arises where lightweight packages are blown outside the landing area (scattered) by wind (gusts) when the mobile vehicle takes off (departs) after transporting the goods.

[0007] Furthermore, as shown in Figure 10, when the cargo being transported by the mobile vehicle is lightweight, a problem arises where the cargo is blown (scattered) outside the landing and takeoff area due to gusts of wind generated by the hovercraft or exhaust from the jet engines of the mobile vehicle.

[0008] This invention was devised to solve the problems described above. Specifically, the object of this invention is to provide a mobile port and a method for preventing cargo from falling, which can launch and land a mobile body in a location free of obstacles higher than the launch / landing surface, and which can prevent cargo from being blown away (scattered) by gusts of wind when the mobile body is launched. [Means for solving the problem]

[0009] According to the present invention, a landing and departure surface on which a mobile body that transports cargo arrives and departs, An outer peripheral plane that surrounds the landing and takeoff surface in a plan view, and whose upper surface is substantially flush with the landing and takeoff surface when the moving body arrives, A mobile port is provided, which includes a luggage scattering prevention device that prevents the luggage from moving from the departure / arrival surface to the outer peripheral plane when the mobile body departs.

[0010] Furthermore, according to the present invention, there is a method for preventing luggage from falling from the above-mentioned mobile port, An arrival step in which the landing surface and the upper surface of the outer peripheral plane are held substantially flush upon arrival of the moving body, A method for preventing luggage from falling from a mobile port is provided, comprising a departure step in which the luggage scattering prevention device prevents the luggage from moving from the departure / arrival surface to the outer peripheral plane when the mobile body departs.

Advantages of the Invention

[0011] According to the present invention, since the upper surface of the outer peripheral plane surrounding the landing surface is substantially flush with the landing surface in a plan view when the moving body arrives, the moving body can be landed at a place where there is no obstacle higher than the landing surface.

[0012] In addition, since it is provided with a luggage scattering prevention device that prevents the movement of luggage from the landing surface to the outer peripheral plane when the moving body departs, it is possible to prevent the luggage from being blown away (scattered) by the gust when the moving body takes off.

Modes for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described based on the drawings. In the figures, the same reference numerals are given to the common parts, and duplicate explanations are omitted.

[0015] FIG. 1 is an explanatory diagram of the mobile port 100, where (A) is a perspective view and (B) is a top view.

[0016] In FIG. 1, the mobile port 100 has a port surface 10 on its upper surface. In this example, the port surface 10 is a rectangular plane with a constant width and length in plan view. Also, in this example, the port surface 10 is an entirely flat horizontal plane, and is divided into a landing / take-off surface 12 where the mobile body 2 for transporting the luggage 1 lands and takes off, and an outer peripheral plane 14 surrounding the landing / take-off surface 12 in plan view.

[0017] In this example, the size of the port surface 10 is, for example, a width of 2 m and a length of 5 m, and the size of the landing / take-off surface 12 is, for example, a width of 1.5 m and a length of 1.5 m. Also in this example, the landing / take-off surface 12 is located at one end side in the length direction of the port surface 10. Note that this size and configuration are just an example, and other sizes and configurations may also be possible.

[0018] The size of the landing / take-off surface 12 in plan view is set to a size such that the mobile body 2 can land and take off reliably. The surface of the landing / take-off surface 12 is preferably made of a material on which the luggage 1 is not likely to slip. This material is, for example, rubber or felt, and is configured to prevent or reduce the sliding of the luggage 1 on the surface of the landing / take-off surface 12.

[0019] When the mobile body 2 arrives, the upper surface of the outer peripheral plane 14 is substantially flush with the landing / take-off surface 12. The size of the outer peripheral plane 14 in plan view is set to a range such that it does not deviate even if the position fluctuates due to wind, rain, etc. when the mobile body 2 arrives or departs. Therefore, there may be a component (for example, a take-off detection device described later) at a position higher than the landing / take-off surface 12 outside the outer peripheral plane 14. Note that "substantially flush" includes a step that does not adversely affect the landing of the mobile body 2 and the release of the luggage 1. This step is, for example, within 1 - 2 mm.

[0020] With the above configuration, the upper surface of the outer perimeter plane 14 surrounding the landing surface 12 in a plan view is substantially flush with the landing surface 12 when the mobile body 2 arrives, so that the mobile body 2 can be launched and launched in a location where there are no obstacles higher than the landing surface. In other words, when the mobile unit 2 arrives, there are no obstacles inside the port surface 10 that are higher than the landing / takeoff surface. Therefore, even if the mobile unit 2's position changes due to wind, rain, etc., it can take off and land at any position on the port surface 10 without any problems, thus maintaining ease of takeoff and landing.

[0021] In Figure 1, reference numeral 15 denotes a luggage door provided on the landing / takeoff surface 12, reference numeral 16 denotes a luggage retrieval opening, and reference numeral 17 denotes a maintenance door. After landing and taking off, the mobile unit 2 releases (ejects) cargo 1 directly above the cargo door 15, and then takes off, leaving cargo 1 above the cargo door 15. The mobile port 100 is configured to fully open the luggage door 15, or lower it completely, to store the luggage 1 inside, and then to retrieve the luggage 1 from the luggage retrieval opening 16. The maintenance door 17 is a cargo door that allows people to access the inside of the mobile port 100. Note that these are not mandatory, and some or all of them may be omitted.

[0022] Figure 2 is an overall diagram of the mobile port 100. In this figure, the mobile port 100 is equipped with a cargo scattering prevention device 20 and a takeoff detection device 50.

[0023] The luggage scattering prevention device 20 has the function of preventing the luggage 1 from moving from the landing / departure surface 12 to the outer perimeter plane 14 (for example, scattering due to a gust of wind) when the mobile body 2 departs. A specific example of the luggage scattering prevention device 20 will be described later.

[0024] The takeoff detection device 50 is, for example, a 3D lidar installed below or outside the outer perimeter plane 14.

[0025] 3D LiDAR is a type of sensor that uses lasers to measure the distance to an object, and because its measurement range is three-dimensional, it can acquire spatial information. By utilizing this property, the movement of mobile object 2 when it takes off can be captured in detail. Specifically, the 3D LiDAR captures changes in the shape and position of the mobile object 2 in real time, and uses this to detect when the mobile object 2 takes off. The moment takeoff is detected, the cargo scattering prevention device 20 activates to prevent the cargo 1 from being scattered by the wind (gusts) that occur at departure. Thus, using 3D LiDAR enables highly accurate takeoff detection, improving the reliability and efficiency of mobile delivery. Furthermore, 3D LiDAR calculates distance by emitting multiple lasers and measuring the time of reflected lasers. Therefore, it is possible to accurately capture the movement of mobile object 2 regardless of the angle at which it takes off.

[0026] The takeoff detection device 50 may be, for example, an anemometer, a sound level meter, an ultrasonic sensor, an optical sensor, or a weighing scale installed below or outside the outer perimeter plane 14. These sensors can detect the takeoff of the mobile object 2 based on changes in wind speed, noise, illumination, or weight.

[0027] Figure 3 is an overall flowchart of the method for preventing cargo from falling at the mobile port 100. In this diagram, the method for preventing luggage from falling uses the mobile port 100 described above and consists of an arrival step S1 and a departure step S2. In arrival step S1, the landing surface 12 and the upper surface of the outer peripheral plane 14 are kept substantially flush with each other upon arrival of the moving body 2. In departure step S2, the luggage scattering prevention device 20 prevents the luggage 1 from moving from the landing / takeoff surface 12 to the outer perimeter plane 14 when the mobile body 2 takes off. The takeoff of the mobile body 2 is detected by the takeoff detection device 50 described above.

[0028] According to the apparatus and method described above, a luggage scattering prevention device 20 is provided to prevent the luggage 1 from moving onto the outer perimeter plane 14 when the mobile body 2 departs, and the luggage scattering prevention device 20 prevents the luggage 1 from moving from the departure / arrival surface 12 to the outer perimeter plane 14 when the mobile body 2 departs.

[0029] Furthermore, the aforementioned takeoff detection device 50 detects the departure of the mobile body 2 and switches from the arrival step S1 to the departure step S2 immediately after takeoff. This prevents the lightweight cargo 1 from being blown outside the takeoff and landing area by a gust of wind immediately after the mobile unit 2 takes off.

[0030] (First Embodiment) Figure 4 is an explanatory diagram of the mobile port 100 of the first embodiment. In this figure, (A) is a plan view similar to Figure 1(B), and (B) is a cross-sectional view of (A) along line BB.

[0031] In Figure 4(A), a gap 18 of a certain width is preferably provided between the outer edge of the contact surface 12 and the outer peripheral plane 14. In Figure 4(B), the luggage scattering prevention device 20A of the first embodiment includes a scattering prevention member 22 and a prevention member moving device 24. In this example, the scattering prevention member 22 and the prevention member moving device 24 are the lifting fence 23 and the fence lifting device 25. The following describes the case of the lifting fence 23 and the fence lifting device 25.

[0032] The lifting fence 23 is provided on the outer perimeter plane 14 and is configured to be movable between a retracted position R where the upper end 23a is located below the outer perimeter plane 14 and a protruding position P where the upper end 23a is located above the outer perimeter plane 14. In this example, the lifting fence 23 is located in the gap 18 between the outer edge of the landing surface 12 and the outer peripheral plane 14, and consists of a plurality of poles positioned to surround the outer edge of the landing surface 12, and connecting members that connect adjacent poles to each other. The upper end connecting member, located at the upper end of the connecting members, has a width corresponding to the gap 18 at the outer edge of the landing surface 12, and is designed to fill the gap 18 in the retracted position R. Furthermore, the lifting rail 23 is guided by a guide (not shown) so as to be able to move up and down between the retracted position R and the protruding position P, and is designed to maintain its position at both the retracted position R and the protruding position P.

[0033] The fence lifting device 25 is a drive device that holds the lifting fence 23 in the retracted position R when the mobile body 2 arrives, and moves the lifting fence 23 to the protruding position P when the mobile body 2 departs.

[0034] The drive source for the prevention member moving device 24 (fence lifting device 25) is preferably an electric motor, a solenoid (electromagnet), or a pneumatic cylinder. Using an electric motor, the anti-scattering member 22 (lifting fence 23) can be moved by a well-known mechanism. If a portion of the anti-scattering member 22 is made of metal (iron), the anti-scattering member 22 can also be moved by using an electromagnet to pull it towards it. When the power is on, the anti-scattering member 22 is pulled towards the retracted position R, and when the takeoff of the moving body is detected, the lock is released and the anti-scattering member 22 is ejected to the protruding position P by a spring or the like. The anti-scattering member 22 can also be moved using a pneumatic cylinder that utilizes air pressure. In this case, it is preferable to move the anti-scattering member 22 using compressed air generated by a compressor.

[0035] In the first embodiment of the cargo fall prevention method, in arrival step S1, with the anti-scattering member 22 (lifting fence 23) in the retracted position R, the mobile body 2 is launched and launched to the launching / landing surface 12, and the cargo 1 is released to the transport point on the launching / landing surface 12 (for example, directly above the cargo door 15). Next, in the departure step S2, the scattering prevention member 22 (elevating fence 23) is raised to the protruding position P when the mobile body 2 departs (preferably immediately after takeoff).

[0036] Specifically, the mobile unit 2 arrives at the mobile unit port 100 carrying cargo, and the mobile unit 2 arrives at the departure / arrival point with the scattering prevention member 22 (elevating fence 23) in the retracted position R. Next, the mobile unit 2 releases the cargo to the transport point (for example, directly above the cargo door 15). Next, immediately after the mobile body 2 takes off, the takeoff detection device 50 is activated, raising the anti-scattering member 22 (elevating fence 23) to the protruding position P, thereby preventing the cargo 1 from scattering.

[0037] The luggage scattering prevention device 20A of the first embodiment is not limited to the example described above. For example, the position of the scattering prevention member 22 (lifting fence 23) is not limited to the gap 18 between the outer edge of the landing surface 12 and the outer peripheral plane 14, but can be any position on the outer peripheral plane 14. Alternatively, the scattering prevention member 22 (lifting fence 23) may be composed of multiple independent lifting poles (not shown), and each lifting pole may be individually controlled by multiple individual lifting devices (not shown). Furthermore, the scattering prevention member 22 is not limited to the lifting fence 23 described above, and can be any member that is movable between the protruding position P and the retracted position R.

[0038] In the cargo scattering prevention device 20A of the first embodiment, upon arrival, all scattering prevention members 22 (lifting fences 23) are in a retracted state (retracted position R), and the landing / takeoff surface (port surface 10) is kept smooth. As a result, the moving object can be safely taken off and landed. The takeoff detection device 50 detects when the transport of cargo 1 is complete and the mobile unit 2 is ready to take off. When the takeoff of mobile unit 2 is detected, the prevention member moving device 24 (fence lifting device 25) activates, and the scattering prevention member 22 (lifting fence 23) rapidly moves to the protruding position P. The scattering prevention member 22 (lifting fence 23), having moved to the protruding position P, catches cargo 1 that is about to be blown away by the wind, preventing cargo 1 from scattering.

[0039] According to the apparatus and method of the first embodiment described above, the scattering prevention member 22 (lifting fence 23) is in the retracted position R when the mobile body 2 arrives, so there are no obstacles located above the outer peripheral plane 14 inside the port surface 10. Therefore, even if the position of the mobile body 2 changes due to wind and rain, it can take off and land at any position on the port surface 10 (take-off / landing surface 12 and outer peripheral plane 14) without any problems, and the ease of take-off and landing can be maintained.

[0040] Furthermore, when the mobile unit 2 departs, the anti-scattering member 22 (elevating fence 23) is moved to the protruding position P, so the anti-scattering member 22 (elevating fence 23) at the protruding position P surrounds the luggage 1 located on the takeoff / landing surface 12, including the luggage door 15. Therefore, it is possible to prevent the lightweight luggage 1 from being blown (scattered) outside the anti-scattering member 22 (elevating fence 23) by a gust of wind immediately after the mobile unit 2 takes off.

[0041] (Second Embodiment) Figure 5 is an explanatory diagram of the mobile port 100 of the second embodiment. In this figure, (A) is a plan view similar to Figure 1(B), and (B) is a cross-sectional view of (A) along line BB.

[0042] In Figure 5(B), the cargo scattering prevention device 20B has a landing surface lifting device 26 that raises and lowers the landing surface 12 relative to the outer peripheral plane 14.

[0043] In this example, the landing surface 12 is configured to move up and down between a lowered position D, where part or all (all in this example) of the landing surface 12 is located below the outer peripheral plane 14, and an elevated position U, where the entire landing surface 12 is substantially flush with the outer peripheral plane 14. Furthermore, the landing surface 12 is guided by a guide (not shown) so as to be able to move up and down between a lowering position D and an upward position U, and is designed to maintain its position at both the lowering position D and the upward position U.

[0044] The landing surface lifting device 26 positions the entire landing surface 12 substantially flush with the outer peripheral plane 14 when the mobile body 2 arrives, and lowers part or all (in this example, all) of the landing surface 12 below the outer peripheral plane 14 after the mobile body 2 takes off. The drive source for the landing surface lifting device 26 is preferably an electric motor, a solenoid (electromagnet), or a pneumatic cylinder. The other configurations are the same as in the first embodiment.

[0045] In the second embodiment of the cargo fall prevention method, in arrival step S1, the moving body 2 is launched and launched onto the launch / landing surface 12 with the entire launch / landing surface 12 positioned substantially flush with the outer peripheral plane 14, and the cargo 1 is released to the transport point on the launch / landing surface 12. Next, in the departure step S2, at the time of departure of the mobile body 2 (preferably immediately after takeoff), a part or all (in this example, all) of the takeoff and landing surface 12 is lowered below the outer peripheral plane 14.

[0046] Specifically, when mobile unit 2 arrives at mobile unit port 100 carrying cargo, and with the take-off / landing surface 12 in the raised position U, mobile unit 2 takes off and lands at the take-off / landing point (take-off / landing surface 12). Next, the mobile unit 2 releases the cargo to the transport point (for example, directly above the cargo door 15). Next, immediately after the mobile unit 2 takes off, the takeoff detection device 50 is activated, lowering the takeoff and landing surface 12 to the lowered position D, and the lowered shape of the takeoff and landing surface 12 prevents the cargo 1 from scattering.

[0047] Furthermore, the luggage scattering prevention device 20B of the second embodiment is not limited to the example described above. For example, the landing / takeoff surface 12 may be a concave surface in which the central portion (position of the luggage door 15) is located lower than the peripheral portion (upper surface of the outer periphery). In this embodiment, the landing surface 12 of the mobile port 100 is partially concave. This concave portion is less susceptible to wind, and the shape allows the cargo 1 to naturally gather towards the center. Specifically, the central part of the takeoff / landing surface 12 is lower by several centimeters compared to the surrounding area. This structure prevents the cargo from being blown in an unintended direction, as the wind force generated when the mobile unit 2 takes off directly hits the cargo, creating a step around it. The concave portion can be made into an optimal shape depending on the shape and size of the luggage, such as a circle, ellipse, or polygon. Furthermore, it is advisable to use a material such as rubber or felt on the bottom surface of the concave portion to prevent the luggage from slipping.

[0048] Furthermore, the lifting portion operated by the landing surface lifting device 26 is not limited to the entire landing surface 12, but may be a part of it. For example, only the luggage door 15 of the landing / takeoff surface 1 may be raised or lowered.

[0049] According to the apparatus and method of the second embodiment described above, when the mobile body 2 arrives, the entire landing / departure surface 12 is positioned substantially flush with the outer peripheral plane 14, so there are no obstacles higher than the landing / departure surface inside the port surface 10. Therefore, even if the position of the mobile body 2 changes due to wind and rain, etc., it can land and depart at any position on the port surface 10 (landing / departure surface 12 and outer peripheral plane 14) without any problems, and the ease of landing and departure can be maintained.

[0050] Furthermore, when the mobile unit 2 takes off, part or all of the takeoff / landing surface 12 is lowered below the outer peripheral plane 14, so the outside of the lowered portion (for example, the inner edge of the outer peripheral plane 14) surrounds the luggage 1 located on the takeoff / landing surface 12, including the luggage door 15. Therefore, it is possible to prevent the lightweight luggage 1 from being blown (scattered) outside the lowered portion by a gust of wind immediately after the mobile unit 2 takes off.

[0051] Figure 8 is an explanatory diagram of a modified example of the mobile port 100 of the second embodiment. In this example, the landing surface lifting device 26 is a spring device 26a that biases part or all of the landing surface upward. This configuration allows the spring biasing force to position the entire landing surface substantially flush with the outer perimeter plane upon arrival of the mobile body 2, and after the mobile body departs, the weight of the cargo can lower part or all of the landing surface below the outer perimeter plane, thus providing the advantage of not requiring electricity.

[0052] (Third embodiment) Figure 6 is an explanatory diagram of the mobile port 100 of the third embodiment, and is a cross-sectional view similar to that of Figure 4(B).

[0053] In this figure, the landing surface 12 has a plurality of dispersed recesses 28. The recesses 28 are preferably holes or grooves that are recessed below the landing surface 12. The recesses 28 are set to a size and shape that does not interfere with the landing and takeoff of the mobile body 2. Furthermore, the recesses 28 are distributed across the entire landing and takeoff surface 12, including the luggage door 15, and are set to prevent the luggage 1 from being scattered by gusts of wind by suctioning the underside of the luggage 1 at any position.

[0054] The third embodiment of the cargo scattering prevention device 20C has a suction device 30 that sucks air from a plurality of recesses 28. The suction device 30 sucks air from multiple recesses 28 immediately after the mobile body 2 takes off, thereby suctioning the underside of the cargo 1.

[0055] In the third embodiment of the cargo fall prevention method, in arrival step S1, the suction device 30 is not activated, and with the air in the recess 28 equal to atmospheric pressure, the mobile body 2 is launched and launched to the launch / landing surface 12, and the cargo 1 is released to the transport point on the launch / landing surface 12. Next, in departure step S2, the suction device 30 sucks air from the multiple recesses 28 when the mobile body 2 departs (preferably immediately after takeoff) to suction the underside of the luggage 1. Furthermore, in this departure step S2, the suction device 30 may be activated before the arrival of the mobile body 2 to reduce the effects of wind caused by downwash and to suction the underside of the luggage.

[0056] According to the apparatus and method of the third embodiment described above, there are always no obstacles located above the landing surface 12 and the outer peripheral plane 14 at the same level inside the port surface 10. Therefore, by not activating the suction device 30 when the mobile body 2 arrives and by making the air in the recess 28 equal to atmospheric pressure, the mobile body 2 can take off and land at any position on the port surface 10 without being affected by the recess 28, thus maintaining ease of takeoff and landing.

[0057] Furthermore, when the mobile unit 2 departs, it sucks air from multiple recesses 28 to suction the underside of the cargo 1. The negative pressure in the recesses 28 prevents the cargo 1 from being blown away by gusts of wind through suction.

[0058] (Fourth Embodiment) Figure 7 is an explanatory diagram of the mobile port 100 of the fourth embodiment, and is a plan view similar to Figure 1(B).

[0059] In this figure, the luggage scattering prevention device 20D of the fourth embodiment is a plurality of protrusions 32 distributed on the upper surface of the landing surface 12, which includes the luggage door 15. The protrusion 32 is, for example, made of rubber, and is set to a size and shape that does not interfere with the launching and landing of the mobile body 2. The shape of the protrusion 32 may be, for example, a hemispherical shape or a pyramidal shape, but it may also be any other shape. Furthermore, the protrusions 32 are distributed across the entire landing surface 12, including the luggage door 15, and the upper ends of the multiple protrusions 32 are set to be substantially flush with the upper surface of the outer peripheral plane 14 when the moving body 2 arrives. The protrusions 32 may also be distributed on the upper surface of the outer peripheral plane 14.

[0060] With the configuration of the cargo scattering prevention device 20D described above, the upper ends of the multiple protrusions 32 are set to be substantially flush with the upper surface of the outer peripheral plane 14 when the moving body 2 arrives. Therefore, when the mobile body 2 arrives, there are no obstacles located above the outer peripheral plane 14 inside the port surface 10, so the mobile body 2 can take off and land at any position on the port surface 10 (the take-off / landing surface 12 and the outer peripheral plane 14) without any problems, and ease of take-off and landing can be maintained. Furthermore, when the mobile vehicle 2 departs, the luggage 1 rests on the upper ends of multiple protrusions 32 on the landing surface 12, including the luggage door 15, and friction occurs between the luggage 1 and the upper ends of the protrusions 32. This friction supports the underside of the luggage 1 with the multiple protrusions 32 at any position, preventing the luggage 1 from being blown away by gusts of wind.

[0061] (Fifth embodiment) Figure 9 is an explanatory diagram of the mobile port 100 of the fifth embodiment, and is a side view similar to Figure 4(B). In this example, the cargo scattering prevention device 20E has movable clamp arms 34 provided around the landing surface. The clamp arm 34 is configured to grip the load when the moving object departs, preventing the load from moving.

[0062] Alternatively, a magnetic material may be attached to the underside of the luggage, and a luggage scattering prevention device may generate a magnetic force when the moving object departs, attracting and securing the underside of the luggage. Furthermore, the method of fixation may be either physical gripping or the use of static electricity.

[0063] Furthermore, the cargo scattering prevention devices 20 of the first to fifth embodiments may be used individually or in combination of multiple devices. For example, the recess 28 of the third embodiment may be provided at the center of the protrusion 32 of the fourth embodiment. In addition, a luggage scattering prevention device according to the first or second embodiment may be installed in conjunction with this.

[0064] Furthermore, the aforementioned luggage scattering prevention devices 20, 20A, 20B, 20C, 20D, and 20E may be composed of shock-absorbing materials (urethane, rubber) to mitigate the impact on luggage when the moving vehicle is launched or landed.

[0065] In the first to fifth embodiments described above, the mobile body 2 is a drone. When the mobile body 2 is a drone, the mobile body port 100 is a drone port, the takeoff / landing surface 12 is a takeoff / landing surface, and arrival means landing, while departure means takeoff. Furthermore, the mobile device 2 is not limited to a drone, but may also be a vehicle, an automated guided vehicle (AGV), a hovercraft, etc.

[0066] As described above, according to the embodiment of the present invention, the upper surface of the outer peripheral plane 14 surrounding the landing surface 12 in a plan view is substantially flush with the landing surface 12 when the mobile body 2 arrives, so the mobile body can be launched and launched in a location where there are no obstacles higher than the landing surface.

[0067] Furthermore, since the mobile unit 2 is equipped with a luggage scattering prevention device 20 that prevents the luggage 1 from moving onto the outer perimeter plane 14 when the mobile unit 2 departs, it is possible to prevent the lightweight luggage from being scattered outside the takeoff and landing area by gusts of wind when the mobile unit takes off.

[0068] Furthermore, the present invention provides the following additional effects. (1) The mobile unit 2 can safely take off and land without colliding with fences or other obstacles. With conventional technology, it was necessary to take off and land the mobile unit 2 inside a fence, which carried the risk of crashing into the fence. (2) The structure of the mobile port 100 can be kept simple while enabling efficient delivery. In particular, by designing the mobile port 100 with wind force in mind, a mobile delivery system can be constructed that can be operated safely even in bad weather (strong winds), thereby improving the reliability and efficiency of mobile delivery. (3) The process of taking off and landing of Mobile Unit 2 can be automated, minimizing human intervention. With conventional technology, human operation and monitoring were required for the taking off and landing of Mobile Unit 2.

[0069] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. [Explanation of Symbols]
