Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an environmentally friendly electric UAV. Background Technology

[0002] Electric unmanned aerial vehicles (UAVs) are unmanned aircraft that use electricity as their power source, generating lift and propulsion through motors driving propellers. Due to their environmental friendliness, ease of operation, and low noise, they are widely used in various fields.

[0003] In existing drone applications, when external attachments are needed to carry external objects, complex mechanical structures or manual installation methods are typically employed. Some drones require operators to use specialized tools to disassemble and install attachment devices, which not only increases the difficulty and time cost of operation, but also makes the process cumbersome for non-professionals, increasing the risk of installation errors or damage to drone components. Meanwhile, when drones transport small items, they often lack dedicated, relatively enclosed, and secure storage spaces. Small items can usually only be placed on the surface of the drone or secured with simple straps. These items are easily affected by external environmental factors. Therefore, an environmentally friendly electric drone is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an environmentally friendly electric unmanned aerial vehicle (UAV) to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly electric drone, comprising a drone body, the drone body including a frame, a battery compartment provided inside the frame, motors installed at the four corners of the top of the frame, and propeller blades fixed to the output shaft end of the motors; A storage box is fixed to the lower side of the frame, and the inside of the storage box is used to place small items. The storage box has a door hinged to one side, and a locking assembly is provided on one side of the storage box for opening and closing the door. The locking assembly is provided with an external attachment assembly at its bottom, which is used for external suspension and loading. The external component includes a housing, and a first limiting groove is provided inside the housing. Two rotating shafts are rotatably connected to the inner wall of the first limiting groove via bearings. The locking assembly includes a support rod, one end of which is fixed with a first locking block, and a handle is fixed to one side of the support rod.

[0006] Preferably, as described above, a synchronous pulley is fixedly sleeved on the outer side of the rotating shaft, a synchronous belt is wound around the outer side of the two synchronous pulleys, and two connecting rods are fixed on the outer side of the synchronous belt.

[0007] Preferably, as described above, a sliding rod is fixed to one side of the connecting rod, and a plurality of hanging holes are opened on one side of the sliding rod, with a hook connected to the inside of the hanging holes.

[0008] Preferably, as described above, the inner wall of the first limiting groove is fixed with a multi-stage electric push rod, and one side of one of the connecting rods is fixed to the push rod end of the multi-stage electric push rod. When the push rod of the multi-stage electric push rod extends, the two slide rods simultaneously extend out from both sides of the housing.

[0009] Preferably, the inner wall of the first limiting groove is provided with two first sliding grooves, and the sliding rod is slidably connected to the inner side of the first limiting groove via a sliding rail.

[0010] Preferably, the inner wall of the storage box is provided with a second limiting groove, and a limiting block is fixed to the inner wall of the second limiting groove. The limiting block is located on the lower side of the support rod.

[0011] Preferably, one side of the support rod is hinged to the inner wall of the second limiting groove, and the inner wall of the second limiting groove is provided with a second sliding groove and an insertion groove.

[0012] Preferably, as described above, a handle fixed to one side of the support rod is slidably connected to the inner side of the second groove, and a spring is connected between the top of the first locking block and the inner wall of the second limiting groove.

[0013] Preferably, as described above, a second locking block is fixed on one side of the box door, and the second locking block is adapted to the inside of the insertion slot; When the first and second locking blocks engage, the door is closed; when the first and second locking blocks disengage, the door is open.

[0014] Preferably, the electrical output terminals of the battery compartment are electrically connected to the input terminals of the motor and the multi-stage electric actuator, respectively, and the housing is fixed to the bottom of the storage box.

[0015] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects: When the external attachment function is needed, the battery compartment simply supplies power to the multi-stage electric actuator. The actuator extends, causing the slide bar to extend out of both sides of the housing, making it convenient for the operator to connect the hook through the suspension hole to hang external objects. When the external attachment is not needed, the actuator end of the multi-stage electric actuator retracts, which drives the slide bar to retract into the housing. The whole process is simple to operate and can quickly enable and disable the external attachment function, improving efficiency.

[0016] By setting up a storage box on the underside of the drone, the storage box can provide a relatively enclosed and safe space for small items, effectively protecting them from external environmental factors, preventing damage or loss due to vibration or collision, and ensuring the integrity of the carried items.

[0017] When small items are placed in the storage box, turning the door will insert the second latch into the insertion slot, engaging the first and second latches. The spring compression force firmly presses the first latch against the second latch, effectively preventing the second latch from dislodging from the insertion slot. This ensures the door remains stably closed, preventing accidental opening during movement or use and protecting the items inside. To open the door, the operator simply pulls the handle diagonally upwards, causing the support rod to rotate around the hinge point, gradually separating the first and second latches. Once completely separated, the second latch can easily dislodge from the insertion slot, allowing the door to open easily. The opening method is simple, requiring no complicated steps or additional tools, making it convenient for operators to quickly retrieve or place small items. Attached Figure Description

Example

[0023] Please see Figure 1-7 The present invention provides a technical solution: an environmentally friendly electric drone, including a drone body 1, a frame 4, a battery compartment 5 inside the frame 4, motors installed at the four corners of the top of the frame 4, and propeller blades 2 fixed to the output shaft of the motors. The drone body 1 and the frame 4 are made of environmentally friendly materials, and the drone body 1 and the frame 4 are made of biodegradable or recyclable environmentally friendly materials, reducing the impact on the environment during the production and disposal stages. A storage box 3 is fixed to the lower side of the frame 4. The inside of the storage box 3 is used to place small items. A door 7 is hinged to one side of the storage box 3. A locking component 8 is provided on one side of the storage box 3. The locking component 8 is used to open and close the door 7. An external attachment component 6 is provided at the bottom of the locking component 8. The external attachment component 6 is used for external suspension and mounting. The shell 61 of the external attachment component 6 is fixed to the bottom of the storage box 3, so that the drone body 1 can carry the items inside the storage box 3 while also suspending external items through the external attachment component 6. The functionality is highly integrated and the structure is compact. The locking component 8 is located on one side of the storage box 3, and the external attachment component 6 below it does not interfere with each other in terms of space utilization.

[0024] The external attachment 6 includes a housing 61, inside which a first limiting groove 62 is provided. The inner wall of the first limiting groove 62 is rotatably connected to two rotating shafts 64 via bearings. The electrical output end of the battery compartment 5 is electrically connected to the input end of the motor and the multi-stage electric push rod 68, respectively. All electric components of the entire machine are powered by the battery compartment 5. The battery compartment 5 simultaneously powers the motor that provides flight power and the multi-stage electric push rod 68 that drives the external attachment 6, ensuring the unity and coordination of functions. The housing 61 is fixed to the bottom of the storage box 3. A synchronous pulley 69 is fixedly sleeved on the outside of the rotating shaft 64. A synchronous belt 63 is wound around the outside of the two synchronous pulleys 69. Two connecting rods 67 are fixed on the outside of the synchronous belt 63.

[0025] A sliding rod 66 is fixed to one side of the connecting rod 67. Several hanging holes 65 are opened on one side of the sliding rod 66. A hook is connected to the inside of the hanging hole 65. The external object is hung and connected through the hook. Multiple hanging holes 65 are opened on the outside of the sliding rod 66. The hole positions can be selected according to the hanging requirements to adapt to external objects of different sizes or weights, thereby improving the hanging flexibility. When the push rod end of the electric push rod extends, it drives one of the connecting rods 67 to move. Through the transmission of the synchronous pulley 69 and the synchronous belt 63, the two sliding rods 66 extend from both sides of the housing 61 at the same time. The hanging holes 65 on the sliding rod 66 can be connected to hooks to achieve symmetrical suspension of external objects.

[0026] When the push rod of the multi-stage electric push rod 68 extends, it drives the two slide rods 66 to extend simultaneously from both sides of the housing 61. The user can hang the object to be suspended in the suspension hole 65 on the slide rod 66 through the hook. When the push rod of the multi-stage electric push rod 68 retracts, it drives the two slide rods 66 to retract synchronously into the housing 61, so that the externally attached object is close to the housing 61, thereby reducing wind resistance, improving stability and protecting the externally attached object during flight.

[0027] The inner wall of the first limiting groove 62 is fixed with a multi-stage electric push rod 68, one side of which of the connecting rods 67 is fixed to the push rod end of the multi-stage electric push rod 68; when the push rod of the multi-stage electric push rod 68 extends, the two slide rods 66 extend out of the two sides of the housing 61 at the same time, and the two slide rods 66 are linked by the synchronous belt 63.

[0028] The inner wall of the first limiting groove 62 is provided with two first sliding grooves 610. A sealing ring (not shown in the figure) is fixed on the inner wall of the first sliding groove 610. The sealing ring is used to seal the gap between the sliding rod 66 and the first sliding groove 610. The sliding rod 66 is slidably connected to the inner side of the first limiting groove 62 through the sliding rail. The sliding rod 66 is slidably connected to the first sliding groove 610 on the inner side of the first limiting groove 62 through the sliding rail, ensuring that the sliding rod 66 maintains linear movement during the extension and retraction process. The suspension holes 65 on the left and right sides move symmetrically. When the UAV is carrying external objects, it can effectively maintain the balance of the UAV body 1 during flight, avoiding the instability of the UAV body 1 caused by the asymmetrical movement of the external device or the deviation of the suspension point position, thus improving the safety and stability of the UAV body 1 during flight.

[0029] The locking assembly 8 includes a support rod 86, with a first locking block 83 fixed to one end of the support rod 86 and a handle 81 fixed to one side of the support rod 86. A second limiting groove 87 is formed on the inner wall of the storage box 3, and a limiting block 85 is fixed to the inner wall of the second limiting groove 87. The limiting block 85 is located below the support rod 86 and is used to restrict the movement of the support rod 86. One side of the support rod 86 is hinged to the inner wall of the second limiting groove 87. The inner wall of the second limiting groove 87 is provided with a second sliding groove 82 and an insertion groove 89. When the door 7 is closed, the second locking block 84 inserts into the insertion groove 89, and the first locking block 83 is spring-loaded. Under the action of spring 88, the first locking block 83 engages with the second locking block 84, forming a mechanical lock. The elastic force generated by the compression of spring 88 presses the first locking block 83 tightly onto the second locking block 84, effectively preventing the second locking block 84 from coming out of the insertion slot 89, so that the door 7 can be stably closed, preventing the door from being accidentally opened during movement or use, and ensuring the safety of the items inside the storage box. When unlocking, the first locking block 83 and the second locking block 84 are separated by sliding the support rod 86 along the second slide groove 82 through the handle 81, and the door 7 can be opened freely. The handle 81 slides in the second slide groove 82, which plays a guiding and limiting role.

[0030] A handle 81 fixed to one side of the support rod 86 is slidably connected to the inner side of the second slide groove 82. A spring 88 is connected between the top of the first locking block 83 and the inner wall of the second limiting groove 87. A second locking block 84 is fixed to one side of the door 7 and is adapted to the inner side of the insertion groove 89. When the first locking block 83 and the second locking block 84 are engaged, the door 7 is in the closed state. When the first locking block 83 and the second locking block 84 are separated, the door 7 is in the open state. The ingenious combination of the support rod 86, the first locking block 83, the second locking block 84, the spring 88 and the insertion groove 89 realizes the stable closing and easy opening of the door 7.

[0031] Working principle: The flight function is powered by the battery compartment 5, which drives the motors mounted at the four corners of the top of the frame 4 to rotate, thereby driving the propeller blades 2 fixed on the motor output shaft to generate lift, enabling the drone to take off, hover, fly and land; When the external function is needed, the battery compartment 5 supplies power to the multi-stage electric actuator 68, and the actuator of the multi-stage electric actuator 68 begins to extend. Since the actuator end of the multi-stage electric actuator 68 is fixed to one side of one of the connecting rods 67, when the actuator extends, it pushes the connecting rod 67 to move along the inner side of the first limiting groove 62. The connecting rod 67 is fixedly connected to the timing belt 63, and the timing belt 63 is wrapped around the timing pulleys 69 on the outer side of the two rotating shafts 64. When one of the connecting rods 67 moves, it drives the timing belt 63 to rotate along the timing pulley 69, thereby pulling the other connecting rod. The two connecting rods 67 move synchronously and are fixed to the corresponding sliding rods 66 respectively. The sliding rods 66 are slidably connected to the inside of the first limiting groove 62 through the slide rail. Finally, the two sliding rods 66 extend synchronously to both sides of the housing 61. The operator can connect the hook through the suspension hole 65 opened on the sliding rod 66 and then hang external objects through the hook. When it is not necessary to hang external objects, the multi-stage electric push rod 68 pushes the rod back and drives the sliding rod 66 to retract into the housing 61 through the above-mentioned reverse linkage. The suspension points on the left and right sides always move symmetrically, maintaining the balance of the UAV body 1 during flight.

[0032] When small items are placed inside the storage box 3, simply turn the door 7. The second locking block 84 fixed on one side of the door 7 will insert into the insertion slot 89 in the second limiting groove 87 on the inner wall of the storage box 3. The first locking block 83 fixed at one end of the support rod 86 and the second locking block 84 will form a locking engagement. At the same time, the spring 88 connected between the top of the first locking block 83 and the inner wall of the second limiting groove 87 will be in a compressed state. The spring force of the spring 88 will press the first locking block 83 tightly onto the second locking block 84, preventing the second locking block 84 from coming out of the insertion slot 89, and finally keeping the door 7 stably closed.

[0033] When it is necessary to open the box door 7, the operator pulls the handle 81 diagonally upward. The handle 81 moves upward, causing the support rod 86 to rotate around the hinge point between it and the inner wall of the second limiting groove 87. At the same time, the spring 88 is further compressed. As the support rod 86 rotates, the first locking block 83 and the second locking block 84 gradually separate. When the two are completely separated, the second locking block 84 can be dislodged from the insertion groove 89. At this time, the operator can open the box door 7 and take out or put in small items.

[0034] In summary, when the external attachment function is needed, the battery compartment 5 only needs to supply power to the multi-stage electric push rod 68. The push rod extends, causing the slide rod 66 to extend out of both sides of the housing 61, making it convenient for the operator to connect the hook through the hanging hole 65 to hang external objects. When the external attachment is not needed, the multi-stage electric push rod 68 can be pushed back to drive the slide rod 66 back into the housing 61. The whole process is simple to operate and can quickly enable and disable the external attachment function, improving the efficiency of use.

[0035] By setting a storage box 3 on the lower side of the drone body 1, the storage box 3 can provide a relatively closed and safe space for small items, effectively protecting the items from the influence of external environmental factors, preventing the items from being damaged or lost due to vibration or collision, and ensuring the integrity of the carried items.

[0036] When small items are placed in the storage box 3, the door 7 is turned, and the second latch 84 inserts into the insertion slot 89. The first latch 83 engages with the second latch 84, and the elastic force generated by the compression of the spring 88 presses the first latch 83 firmly against the second latch 84, effectively preventing the second latch 84 from coming out of the insertion slot 89. This ensures that the door 7 remains stably closed, preventing accidental opening during movement or use and protecting the safety of the items inside the storage box 3. When the door 7 needs to be opened, the operator only needs to pull the handle 81 diagonally upwards to rotate the support rod 86 around the hinge point, causing the first latch 83 and the second latch 84 to gradually separate. Once they are completely separated, the second latch 84 can smoothly disengage from the insertion slot 89, thus easily opening the door 7. The opening method is simple and requires no complicated steps or additional tools, making it convenient for operators to quickly take out or put in small items.
