TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a transport unmanned aerial vehicle capable of carrying work unmanned aerial vehicles. BACKGROUND

[0002] In recent years, unmanned aerial vehicle technology has developed rapidly and has been widely used in agriculture, logistics, firefighting and other fields. Especially in the aspect of work unmanned aerial vehicles (hereinafter referred to as "sub-machines"), its flexibility and high efficiency greatly improve the task execution ability in specific environment, and becomes an important force to promote the development of the industry. With the continuous expansion of application scenarios and the accelerated promotion of technological progress, how to further optimize the overall efficiency of the unmanned aerial vehicle system has become a core issue to be solved in the industry.

[0003] In order to solve the problem of short endurance mileage and limited work range of sub-machines, the current mainstream methods mainly include two types: one is to develop high energy density battery materials to improve endurance time; the second is to use the mode of mother machine transportation, that is, to use large size transport unmanned aerial vehicles (hereinafter referred to as "mother machines") with strong carrying capacity to carry sub-machines to the target area and then release to perform specific tasks. In addition, in the actual operation level, there are also modes of installing sub-machines on mother machines for cooperative work by using bolt fixation or buckle connection and the like.

[0004] However, the existing mother machine design generally has a problem, that is, most of them adopt a single fixed loading form, such as directly connecting sub-machines and mother machines by using bolts or buckles. Such design makes the number of sub-machines that can be carried by a single mother machine extremely limited, and in the case of needing to cover a large area or multiple scattered tasks, more mother machines often have to be dispatched for work, thereby causing the phenomenon of unbalanced allocation of resources, increasing the operation cost and management difficulty, and seriously restricting the operation efficiency and economic practicability of the unmanned aerial vehicle system. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the transportation efficiency of mother machines carrying sub-machines, the present application provides a transport unmanned aerial vehicle capable of carrying work unmanned aerial vehicles.

[0006] The transport unmanned aerial vehicle capable of carrying work unmanned aerial vehicles provided by the present application adopts the following technical scheme:

[0007] A transport unmanned aerial vehicle capable of carrying work unmanned aerial vehicles, comprising a fuselage main body, a carrying frame is arranged on the wings on both sides of the fuselage main body, a slide rail is arranged in the carrying frame for sliding the sub-machines into the carrying frame, a mounting platform is arranged below the belly of the fuselage main body, the mounting platform is vertically distributed with multiple layers, and each layer of the mounting platform is distributed with multiple fixing positions for positioning the sub-machines.

[0008] By adopting the above technical scheme, the wing mounting frames are arranged on both sides of the fuselage body and the multi-layer mounting platform is arranged below the fuselage belly, the number of sub-machines that can be carried by a single mother machine is greatly increased, the slide rails are arranged to facilitate the quick loading and unloading of the sub-machines, the multi-layer arrangement of the mounting platform makes full use of the space resources, improves the transportation efficiency and meets the demand of large-scale or multi-point scattered tasks. This design effectively solves the problem of limited carrying capacity caused by single loading form in the prior art, reduces the number of mother machine scheduling, reduces the operation cost and management complexity.

[0009] Optionally, the multi-layer mounting platform is foldably arranged, vertical multi-stage electric telescopic rods are arranged through the edges on the same side of the multi-layer mounting platform, each layer of the mounting platform is connected to the end of a different stage of the telescopic rod, and the length of the end of each stage of the telescopic rod matches the height of the sub-machine.

[0010] By adopting the above technical scheme, the foldable design of the multi-layer mounting platform effectively reduces the space occupation of the transportation unmanned aerial vehicle in the non-working state, improves the convenience of storage and transportation. Moreover, the multi-layer mounting platform is controlled to expand and shrink through the multi-stage electric telescopic rods, adapts to the sub-machine carrying demand of different quantities, simplifies the loading and unloading process, and enhances the flexibility and practicality of the system.

[0011] Optionally, a locking rod for locking the sub-machine is arranged in the mounting frame, the locking rod is oppositely arranged in two along the direction perpendicular to the length direction of the slide rail, the locking rod comprises a fixed cylinder mounted on the mounting frame, a latch slidably arranged at the end of the fixed cylinder, and a driving piece for adjusting the position of the latch, the two sides of the sub-machine are each provided with a groove corresponding to the latch, and the latch and the groove on the sub-machine are one-to-one corresponding and are inserted and matched.

[0012] By adopting the above technical scheme, when the sub-machine needs to be assembled or recovered, the two oppositely arranged locking rods can form a stable restraining action on the sub-machine in the direction perpendicular to the length of the slide rail, effectively reducing the possibility of position deviation caused by external factors. The precise matching between the latch and the groove on the sub-machine further improves the stability of the locking, greatly reduces the loosening phenomenon that may be caused by vibration or external airflow interference during flight, greatly guarantees the safety and stability of the transportation link, and strengthens the reliable performance of the whole system.

[0013] Optionally, the driving piece comprises an elastic piece arranged in the fixed cylinder and an electromagnet arranged at the end of the latch, the elastic piece connects the latch and the fixed cylinder, a magnet block magnetically attracted to the electromagnet is arranged in the groove on the sub-machine, and a proximity switch electrically connected to the electromagnet is further arranged on the mounting frame. When the sub-machine contacts the proximity switch, the electromagnet magnetically attracts the magnet block, the latch extends out against the elastic force of the elastic piece, is embedded into the groove prearranged on the sub-machine, and realizes the locking action.

[0014] By adopting the technical scheme, when the sub-machine reaches the specified position and triggers the proximity switch, the magnetic attraction force generated between the magnet block and the electromagnet can be used to efficiently and accurately insert the locking rod into the groove of the sub-machine, greatly enhancing the safety and stability of the system during transportation. When releasing the sub-machine, the electromagnet loses its magnetic properties after the proximity switch is moved away, and the spring returns to the fixed cylinder, allowing the sub-machine to smoothly separate from the main machine. The entire process can be smoothly executed without human intervention, effectively improving the automation level.

[0015] Optionally, the sliding rail entrance section is equipped with two symmetrically inclined guide arc plates, and the opening width of the two guide arc plates gradually increases away from the sliding rail.

[0016] By adopting the technical scheme, the two symmetrically inclined guide arc plates with gradually increasing opening width can provide a gradual introduction path for the sub-machine, automatically correcting its attitude and position deviation when approaching the sliding rail, thereby greatly improving the stability and efficiency of the loading process.

[0017] Optionally, an electric push element is provided near the terminal position of the sliding rail on the carrying frame to push the sub-machine out of the carrying frame.

[0018] By adopting the technical scheme, when the sub-machine needs to separate from the main machine after completing the task, the stable pushing force provided by the electric push element ensures that the sub-machine quickly and smoothly leaves the main machine carrying frame. Not only does this improve the automation level of the sub-machine release process, but it also effectively improves the overall system's work efficiency and reliability.

[0019] Optionally, the surface of the carrying frame that contacts the sub-machine is covered with an elastic protective pad.

[0020] By adopting the technical scheme, the elastic protective pad can buffer the impact of external environmental changes, reducing the likelihood of damage to the sub-machine shell and its internal precision components, and improving the stability of the sub-machine during operation.

[0021] Optionally, a wireless charging module is provided on the carrying frame to quickly supply energy to the sub-machine.

[0022] By adopting the technical scheme, the wireless charging module can provide continuous energy supply to the sub-machine during transportation, effectively alleviating the problem of limited task execution time due to insufficient power. Compared with the traditional design that relies solely on the main machine for transportation without the ability to replenish, the addition of the wireless charging module not only improves the overall system's work efficiency, but also enhances the sub-machine's endurance in complex task environments, further expanding the application scenarios and flexibility of the unmanned aerial vehicle system.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The wing-mounted frame on both sides of the fuselage body and the multi-layer mounting platform under the belly greatly increase the number of sub-machines that can be carried by a single mother machine. The slide rail facilitates quick loading and unloading of sub-machines. Combined with the multi-level layout of the mounting platform, space resources are fully utilized to improve transportation efficiency and meet the needs of large-scale or multi-point dispersed tasks. This design effectively solves the problem of limited carrying capacity caused by single loading form in the prior art, reduces the number of mother machine dispatching, reduces operation cost and management complexity;

[0025] 2. The foldable design of the multi-layer mounting platform effectively reduces the space occupation of the transport unmanned aerial vehicle in the non-working state, improves the convenience of storage and transportation. Moreover, the multi-layer mounting platform is controlled to expand and shrink by multi-stage electric telescopic rods, which adapts to the sub-machine carrying demand of different quantities, simplifies the loading and unloading process, and enhances the flexibility and practicality of the system;

[0026] 3. When the sub-machine needs to be assembled or recovered, the two oppositely arranged locking rods can form a stable restraining action on the sub-machine in a direction perpendicular to the length of the slide rail, effectively reducing the possibility of position deviation caused by external factors. The precise fit between the latch and the sub-machine groove further improves the stability of the locking, greatly reduces the possibility of loosening caused by vibration or external airflow interference during flight, greatly ensures the safety and stability of the transportation link, and strengthens the reliable performance of the entire system.
