[0040] Application example:

[0041] In the modern intelligent logistics system, especially in complex terrain mountainous areas, traffic congestion in urban centers and emergency supplies delivery, traditional ground transportation is facing the challenges of low timeliness and poor accessibility. To solve the efficient delivery problem of the last kilometer or even the last tens of kilometers, a strong endurance, convenient maintenance and stable operation of air logistics solution is needed. The logistics unmanned aerial vehicle provided by the application is powered by solid-state battery, which can well adapt to the high-frequency and fast-paced logistics operation demand, and provide reliable air transportation support for e-commerce express, medical emergency, fresh food delivery and other fields.

[0042] In the daily delivery business of fresh e-commerce, logistics unmanned aerial vehicles are deployed in warehouse centers around cities to transport high-value and time-sensitive fresh goods to multiple delivery sites in urban areas. In the morning, the staff first checks the unmanned aerial vehicle before departure, confirms that the unmanned aerial vehicle body 1 is in good condition, and the installation frame 2 and the placement plate 3 are stable and not loose. Then, the staff holds the handle 31 on the surface of the storage box 5, puts the pre-charged solid-state battery body 6 into the storage box 5 stably, and aligns and connects the interfaces of the first wire 7 and the second wire 8 to ensure smooth power supply.

[0043] Then, the staff pushes the battery-loaded storage box 5 along the sliding groove 12 on the top of the assembly plate 4. During the pushing process, the sliding block 13 at the bottom of the storage box 5 slides smoothly along the sliding groove 12, while the transmission tooth plate 14 on its surface is moved; the transmission tooth plate 14 drives the connected gear 15 to rotate, and then drives the first drive gear 16 engaged with it to rotate; the power is transmitted to the transmission gear 18 above through the connecting rod 17, and then the transmission gear 18 drives the second drive gear 19 to rotate, and finally the threaded rod 20 rotates. The rotational movement of the threaded rod 20 is converted into the lateral movement of the extension rod 10 guided by the support column 9, thereby pushing the limiting frame 11 fixed to the front end of the extension rod 10 to tighten inward, and tightly pressing the solid-state battery body 6 from both sides, effectively preventing it from loosening due to vibration during flight.

[0044] When the storage box 5 is fully pushed in until the positioning block 27 on the back of it contacts the baffle 21, the limiting card slot 28 on the top of the positioning block 27 is just aligned with the through hole 26 on the baffle 21. At this time, under the continuous pressure of the return spring 25, the conical positioning block 23 automatically slides down, its end passes through the through hole 26 and accurately clamps into the limiting card slot 28, completing the mechanical locking of the storage box 5. This automatic locking mechanism ensures the absolute stability of the battery compartment during flight, and the staff can quickly judge whether the installation is successful by observing whether the conical positioning block 23 is in place. If you need to replace the battery, you just need to lift the pull rod 24 upward, overcome the elastic force of the return spring 25 to make the conical positioning block 23 disengage from the limiting card slot 28, and then easily pull out the storage box 5.

[0045] After completing the battery installation, the staff will place fresh goods on the placement plate 3 at the bottom of the installation frame 2. When the unmanned aerial vehicle takes off and lands, the buffer pads 32 installed around the bottom of the installation frame 2 can effectively absorb impact energy, protecting the fuselage and goods safe. During flight, the drive mechanism 34 is supported by the connecting rod 33 and drives the propeller 35 to rotate at high speed, providing flight power for the unmanned aerial vehicle. At the same time, the ventilation grooves 30 on both sides of the storage box 5 can promote air circulation, assist the solid-state battery body 6 to dissipate heat during work, and maintain its efficient and safe working state. The protective sleeve frame 29 located on the back of the assembly plate 4 provides dust protection for exposed components such as the transmission gear plate 14, ensuring the long-term reliable operation of the transmission system in variable environments. Through this series of coordinated and orderly operations and applications, the logistics unmanned aerial vehicle realizes the rapid replacement of the battery, the safe transportation of goods, and the stable execution of flight, significantly improving the automation level and operation efficiency of the logistics distribution link.

[0046] Working principle: the unmanned aerial vehicle main body 1 as the core bearing platform of the whole system, the bottom of the installation frame 2 is used to build and support the function module below, the placement plate 3 at the bottom of the installation frame 2 is used to carry the logistics goods, and the assembly plate 4 fixed on the inner wall of the installation frame 2 is used as the core installation base of the battery compartment and its associated mechanism; when the power source needs to be installed or replaced, the operator pushes the storage box 5 along the assembly plate 4 through the handle 31, in this process, the sliding block 13 at the bottom of the storage box 5 slides in the pre-set sliding groove 12 on the assembly plate 4, the transmission gear plate 14 installed on the sliding block 13 moves accordingly, the transmission gear plate 14 drives the connected gear 15 meshing therewith to rotate, the connected gear 15 converts the horizontal linear motion into rotary motion and transmits it to the first drive gear 16, the first drive gear 16 transmits the rotary power upward through the connecting rod 17, the transmission gear 18 at the top of the connecting rod 17 rotates accordingly, the transmission gear 18 drives the second drive gear 19 meshing therewith to rotate, the second drive gear 19 drives the threaded rod 20 to rotate, since the threaded rod 20 is screw-connected with the extension rod 10 inside, the rotary motion of the threaded rod 20 is converted into the lateral linear motion of the extension rod 10, the extension rod 10 slides under the guidance of the support column 9 and pushes the limiting frame 11 at the front end thereof to move inward, so as to tightly press the solid-state battery body 6 placed in the storage box 5 from both sides, realizing the automatic fastening of the battery; when the storage box 5 is pushed to the final position, the positioning block 27 at the back thereof contacts the baffle 21, the limiting clamping groove 28 at the top of the positioning block 27 is aligned with the through hole 26 on the baffle 21, under the continuous pressure of the return spring 25, the conical positioning clamping block 23 slides downward under the guidance of the sleeve frame 22, the tail end thereof passes through the through hole 26 and clamps into the limiting clamping groove 28, completing the mechanical locking of the storage box 5, effectively preventing the battery compartment from accidentally falling out during flight, the locking state can be released by pulling the pull rod 24 upward to overcome the elastic force of the return spring 25; the electric energy is output from the solid-state battery body 6 through the first wire 7 and transmitted to the power utilization system of the unmanned aerial vehicle main body 1 through the second wire 8; during flight, the drive mechanism 34 is supported by the connecting rod 33 and drives the propeller 35 to rotate to generate lift and thrust; during the whole working process, the protective sleeve frame 29 at the back of the assembly plate 4 provides dustproof protection for the transmission gear plate 14, the ventilation grooves 30 on both sides of the storage box 5 promote the heat dissipation of the battery, and the buffer pad 32 at the bottom of the installation frame 2 plays a buffering and damping role during take-off and landing. Through the cooperative operation of the above structures, the quick and reliable installation and stable power supply of the logistics unmanned aerial vehicle power battery are realized, and the smooth execution of the flight task is ensured.
