[0002] Smart cars have formed a certain trend. Whether it is assisted driving or fully autonomous driving, they are all the current research and development directions of smart cars. For example, the existing announcement CN114919487B discloses a smart car carrying a drone ( Figure 16 ) includes a vehicle body, a smart parking compartment mounted on the vehicle body, a drone deployed within the smart parking compartment, and a camera and inflation device on the drone. The smart parking compartment, the drone, and the vehicle control system wirelessly communicate with each other. The smart parking compartment includes a compartment body, an electric compartment door, and a control system. The compartment body is equipped with a locking mechanism for locking the drone and a wireless charging device for charging the drone. The vehicle control system is equipped with a tire pressure monitoring module for detecting tire pressures on all four wheels. The drone can be used to monitor the surrounding environment and other functions.
[0003] The motor of a smart car drone is the core of the drone's power system, directly determining its flight performance. It converts electrical energy into mechanical energy, drives the propeller to rotate to generate lift or thrust, and achieves precise control of the drone's attitude by adjusting the speed of different motors.
[0004] The installation steps for a smart car drone motor include preparation, positioning and fixing, motor steering calibration, electrical connection, and propeller installation. You'll need to prepare a screwdriver, screw glue, insulating gaskets, and a multimeter that match the motor screw specifications. Disconnect the battery power, wear an anti-static wristband, and place the motor on the electrical mounting bracket at the end of the arm. The mounting holes must be aligned with the motor flange holes. Screws must be inserted through the motor flange holes and fastened to the arm. A drone is equipped with a large number of motors, which requires the installation of numerous screws, making screw installation tedious and time-consuming.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The motor body of the drone of the present invention is installed inside the assembly seat. During the assembly process, the handle is grasped to apply a rotational force to the screw rod 2, which causes the screw rod 2 to apply a longitudinal pushing force to the nut. The connecting ring is forced to drive the insertion rod to lift. After the insertion rod is moved out of the socket, a pulling force is applied to the mounting block through the pull rope. The mounting block rotates around the mounting shaft as the axis and applies an extrusion force to the torsion spring at the same time. After the motor body is inserted into the assembly seat and the motor body is located at the lower end of the mounting block, the screw rod rotates in the opposite direction, and the mounting block is reset by the torsion spring torsion elastic support, and drives the clamping block to clamp on the inner wall of the ring groove to fix the motor body, avoiding the installation of a large number of screws. In the process of the mounting block being elastically supported by the torsion spring torsion, the insertion rod is inserted into the socket to limit the mounting shaft to avoid rotation of the mounting shaft, so that the clamping block is stable to use, and the drone motor assembly process is time-saving and labor-saving.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] See also Figures 1 to 15 , the present invention provides three embodiments:
[0037] Example 1:
[0038] A drone motor assembly device includes a support arm 1, a motor body 2, a mounting seat 7, a mounting sleeve 6, a connecting ring 8, a mounting block 12 and a mounting bar 42. The motor body 2 is limited by the assembly seat 5; the motor body 2 includes a base 201, an insert 202, an iron core coil assembly 203 and a shell 204. The base is placed in the assembly seat 5 and is limited by the assembly seat 5. An insert 202 is provided at one end of the base 201, and the iron core coil assembly 203 is inserted into the insert 202. The shell 204 is sleeved on the outside of the iron core coil assembly 203 and fixed to the base, and the shell 204 is fixed by the mounting seat The seat 5 is limited; an assembly seat 5 is provided on one side of the upper end of the support arm 1, and a motor body 2 is provided inside the assembly seat 5. A rotating shaft 9 is provided on the upper end of the motor body 2. A collar 19 is sleeved on the outer wall of the motor body 2. An annular ring groove 23 is provided on the upper end of the collar 19. A mounting seat 7 distributed in an annular array is provided on the upper end of the assembly seat 5. A top block 11 is provided on the upper end of the mounting seat 7. A mounting block 12 is provided below the top block 11. Both ends of the mounting block 12 are provided with a mounting shaft 30 rotatably mounted inside the mounting seat 7. The outer side of the mounting shaft 30 is sleeved with a torsion spring 27 whose two ends are respectively connected to the inner wall of the mounting seat 7 and the outer wall of the mounting block 12;
[0039] The assembler holds the rotary handle 24 and drives the screw rod 2 48 to start rotating. At this time, the connecting ring 8 slides along the guide sleeve 44 on the outer wall of the guide rod 45 to realize sliding guidance. The rotational force of the screw rod 2 48 is transmitted to the thread raceway of the nut 25, prompting the nut 25 to move longitudinally, thereby driving the connecting ring 8 to move longitudinally. When the connecting ring 8 rises, it will generate tension on the insertion rod 26, causing the insertion rod 26 and the support ring 16 to rise together, thereby applying pressure to the spring 15, causing it to shrink under pressure. The positioning component provides support for the upper end of the spring 15. During the sliding process of the insertion rod 26 in the top block 11, the continuous rise will pull the pull rope 18, and the pull rope 18 will then apply tension to the mounting block 12. The mounting block 12 is supported by the mounting shaft 30 for rotation.
[0040] When the mounting shaft 30 rotates, it applies pressure to the torsion spring 27, causing it to twist and contract under the pressure, rotating the mounting block 12 and flipping the clamping block 29 at one end of the mounting block 12. At this point, the drone motor body 2 engages with the clamping block 29 via the collar 19. With the widespread application of drones in agriculture, logistics, surveying and mapping, emergency rescue, and other fields, their production and maintenance efficiency have become core challenges for the industry. Traditional drone motor body 2 installation relies on numerous screws. A single multi-rotor drone typically requires dozens of screws, which is cumbersome and prone to loosening due to vibration. In addition, the connection structure between the propeller and the motor body 2 is complex and requires special tools to adjust. Especially in field operations or emergency maintenance scenarios, the problem of low efficiency is particularly prominent. The present device proposes a screw-free, tool-free quick assembly solution through mechanical linkage and elastic locking design. The lower end of the motor body 2 is placed in the assembly seat 5. Traditional installation relies on a large number of screws, which is time-consuming and easy to loosen. The elastic connection between the clamping block 29 and the annular groove 23 and the locking of the plug block 22 and the positioning groove 33 completely replaces the screws, avoiding the cumbersome and error-prone manual operation.
[0041] Example 2:
[0042] It includes a support arm 1, a motor body 2, a mounting seat 7, a mounting sleeve 6, a connecting ring 8, a mounting block 12 and a mounting strip 42. The motor body 2 is limited by the assembly seat 5; the motor body 2 includes a base 201, an insert 202, an iron core coil assembly 203 and a shell 204. The base is placed in the assembly seat 5 and is limited by the assembly seat 5. An insert 202 is provided at one end of the base 201. The iron core coil assembly 203 is inserted into the insert 202. The shell 204 is sleeved on the outside of the iron core coil assembly 203 and fixed to the base, and the shell 204 is limited by the assembly seat 5. Position; an assembly seat 5 is provided on one side of the upper end of the support arm 1, a motor body 2 is provided inside the assembly seat 5, a rotating shaft 9 is provided on the upper end of the motor body 2, a collar 19 is sleeved on the outer wall of the motor body 2, a collar 19 is provided on the upper end of the collar 19 with an annular ring groove 23, a mounting seat 7 distributed in an annular array is provided on the upper end of the assembly seat 5, a top block 11 is provided on the upper end of the mounting seat 7, a mounting block 12 is provided below the top block 11, and both ends of the mounting block 12 are provided with a mounting shaft 30 rotatably mounted on the inside of the mounting seat 7, and the outer side of the mounting shaft 30 is sleeved with a torsion spring 27 connected to the inner wall of the mounting seat 7 and the outer wall of the mounting block 12 respectively;
[0043] The assembler holds the rotary handle 24 and drives the screw rod 2 48 to start rotating. At this time, the connecting ring 8 slides along the guide sleeve 44 on the outer wall of the guide rod 45 to realize sliding guidance. The rotational force of the screw rod 2 48 is transmitted to the thread raceway of the nut 25, prompting the nut 25 to move longitudinally, thereby driving the connecting ring 8 to move longitudinally. When the connecting ring 8 rises, it will generate tension on the insertion rod 26, causing the insertion rod 26 and the support ring 16 to rise together, thereby applying pressure to the spring 15, causing it to shrink under pressure. The positioning component provides support for the upper end of the spring 15. During the sliding process of the insertion rod 26 in the top block 11, the continuous rise will pull the pull rope 18, and the pull rope 18 will then apply tension to the mounting block 12. The mounting block 12 is supported by the mounting shaft 30 for rotation.
[0044] When the mounting shaft 30 rotates, it applies pressure to the torsion spring 27, causing it to twist and contract under the pressure, rotating the mounting block 12 and flipping the clamping block 29 at one end of the mounting block 12. At this point, the drone motor body 2 engages with the clamping block 29 via the collar 19. With the widespread application of drones in agriculture, logistics, surveying and mapping, emergency rescue, and other fields, their production and maintenance efficiency have become core challenges for the industry. Traditional drone motor body 2 installation relies on numerous screws. A single multi-rotor drone typically requires dozens of screws, which is cumbersome and prone to loosening due to vibration. In addition, the connection structure between the propeller and the motor body 2 is complex and requires special tools to adjust. Especially in field operations or emergency maintenance scenarios, the problem of low efficiency is particularly prominent. The present device proposes a screw-free, tool-free quick assembly solution through mechanical linkage and elastic locking design. The lower end of the motor body 2 is placed in the assembly seat 5. Traditional installation relies on a large number of screws, which is time-consuming and easy to loosen. The elastic connection between the clamping block 29 and the annular groove 23 and the locking of the plug block 22 and the positioning groove 33 completely replaces the screws, avoiding the cumbersome and error-prone manual operation.
[0045] A mounting block 29 is provided on one side of the lower end of the mounting block 12 to engage with the annular groove 23. A socket 17 is provided inside the upper end of the mounting block 12. A plug rod 26 is slidably inserted into the socket 17. A connecting ring 8 is provided on the upper end of the plug rod 26. A nut 25 is provided on one end of the connecting ring 8. A bearing seat 43 is provided on one end of the assembly seat 5. A screw rod 48 threadedly mounted with the nut 25 is rotatably installed inside the upper end of the bearing seat 43. A rotary handle 24 is provided on the upper end of the screw rod 48.
[0046] A guide rod 45 is provided at one end of the assembly seat 5, and a guide sleeve 44 connected to the connecting ring 8 is slidably sleeved on the outer wall of the guide rod 45;
[0047] The lower end of the mounting base 7 and the support arm 1 are both provided with assembly holes 46;
[0048] A ball 13 is rotatably mounted inside one end of the mounting block 12;
[0049] A pull rope 18 is provided on the inner wall of the insertion hole 17, and the upper end of the pull rope 18 is connected to the lower end of the insertion rod 26;
[0050] The outer wall of the upper end of the insertion rod 26 is sleeved with a support ring 16, and the upper end of the support ring 16 is provided with a spring 15 connected to the top block 11. The upper end of the top block 11 is embedded with a sliding sleeve 14, and the upper end of the insertion rod 26 is slidably installed inside the sliding sleeve 14;
[0051] The assembler rotates the handle 24 in the opposite direction, driving the screw rod 24 to rotate in the opposite direction, and the connecting ring 8 drops accordingly. At this time, the spring 15 loses pressure and uses its own elasticity to make the support ring 16 and the insertion rod 26 drop. At the same time, the elastic force of the torsion spring 27 acts on the mounting block 12, causing it to rotate in the opposite direction with the mounting shaft 30 as the axis and reset. The mounting block 12 drives the clamping block 29 to be inserted into the ring groove 23, thereby fixing the collar 19 and then fixing the motor body 2. When the elastic force of the torsion spring 27 acts on the collar 19, the mounting block 12 is inserted into the socket 17 through the insertion rod 26, locking the mounting block 12. This method of assembling the motor body 2 reduces the use of screws, shortens the installation time, does not require additional tools, and is more convenient to install.

[0054] The assembler holds the rotary handle 24 and drives the screw rod 2 48 to start rotating. At this time, the connecting ring 8 slides along the guide sleeve 44 on the outer wall of the guide rod 45 to realize sliding guidance. The rotational force of the screw rod 2 48 is transmitted to the thread raceway of the nut 25, prompting the nut 25 to move longitudinally, thereby driving the connecting ring 8 to move longitudinally. When the connecting ring 8 rises, it will generate tension on the insertion rod 26, causing the insertion rod 26 and the support ring 16 to rise together, thereby applying pressure to the spring 15, causing it to shrink under pressure. The positioning component provides support for the upper end of the spring 15. During the sliding process of the insertion rod 26 in the top block 11, the continuous rise will pull the pull rope 18, and the pull rope 18 will then apply tension to the mounting block 12. The mounting block 12 is supported by the mounting shaft 30 for rotation.
[0055] When the mounting shaft 30 rotates, it applies pressure to the torsion spring 27, causing it to twist and contract under the pressure, rotating the mounting block 12 and flipping the clamping block 29 at one end of the mounting block 12. At this point, the drone motor body 2 engages with the clamping block 29 via the collar 19.

At the same time, the elastic force of the torsion spring 27 acts on the mounting block 12, causing it to rotate in the opposite direction with the mounting shaft 30 as the axis and reset. The mounting block 12 drives the clamping block 29 to be inserted into the annular groove 23, thereby fixing the collar 19 and then fixing the motor body 2. When the elastic force of the torsion spring 27 acts on the collar 19, the mounting block 12 is inserted into the socket 17 through the insertion rod 26 to lock the mounting block 12. This method of assembling the motor body 2 reduces the use of screws, shortens the installation time, does not require additional tools, and is more convenient to install.
[0063] The outer side of the rotating shaft 9 is sleeved with a mounting sleeve 6, and blades 3 are provided at both ends of the mounting sleeve 6;
[0064] The interior of the upper end of the rotating shaft 9 is hollow, and the outer wall of the rotating shaft 9 is sleeved with a second collar 34. The upper end of the second collar 34 is provided with positioning rods 35 distributed in a ring array. The lower end of the mounting sleeve 6 is provided with positioning holes 47 distributed in a ring array and slidably plugged with the positioning rods 35.
[0065] The shaft 9 has symmetrically distributed travel grooves 21 at both ends, and the inner walls of the mounting sleeve 6 have positioning grooves 33 corresponding to the travel grooves 21. The travel grooves 21 are slidably inserted into the insert block 22 with one end inserted into the positioning groove 33.
[0066] A screw hole 20 is formed inside the upper end of the rotating shaft 9. A screw rod 31 is threadedly installed inside the screw hole 20. A torsion ring 10 is provided at the upper end of the screw rod 31. An extrusion cone 32 is provided at the lower end of the screw rod 31. A mounting bar 42 is provided at one end of the insert block 22. The outer wall of the mounting bar 42 is sleeved with a limit ring 4. A spring 3 41 connected to the limit ring 4 and the inner wall of the rotating shaft 9 is sleeved on the outer side of the mounting bar 42. A ball 28 rotatably mounted on the inner end of the mounting bar 42 is rotatably installed with the extrusion cone 32.
[0067] The lower end of the torsion ring 10 is provided with tooth grooves 37 distributed in an annular array, and a latch 36 is slidably inserted into the tooth grooves 37. The upper end of the mounting sleeve 6 is provided with a mounting hole 40, and a second spring 39 is slidably inserted into the mounting hole 40. The upper end of the second spring 39 is provided with a travel rod 38 connected to the latch 36, and one end of the travel rod 38 is provided with a pressure strip;
[0068] After the drone motor body 2 is assembled, the mounting sleeve 6 is inserted into the positioning rod 35 through the positioning hole 47 to achieve positioning, and the pressure strip is pressed to apply pressure to the stroke rod 38 to disengage the latching tooth 36 from the slot. At the same time, pressure is applied to the spring 2 39 to cause it to shrink under pressure. At the same time, the torsion ring 10 is held and the screw 1 31 is rotated. The screw 1 31 descends longitudinally in the screw hole 20, pushing the extrusion cone 32 to apply pressure to the ball 2 28. During the descent of the extrusion cone 32, a gradually increasing pressure is applied to the mounting component. This pressure is transmitted through the mounting strip 42 and the limit ring 4. The screw 21 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened. The screw 22 is then tightened and the screw 22 is tightened.
[0069] Only the handle 24 needs to be manually rotated and the pressure strip pressed, without any tools. It is suitable for quick field maintenance and mass production. The ring groove 23 and the block 29 can match a variety of motor body 2 outer diameters. The positioning rod 35 and the positioning hole 47 support multi-specification propellers. It has strong scalability and is suitable for UAV production lines. It can realize the assembly of the motor body 2 and the propeller in seconds, significantly reducing labor costs. Damaged parts can be quickly replaced during field operations, improving mission continuity. The elastic locking mechanism avoids the risk of crashing caused by loosening of traditional screws due to vibration, and enhances safety. The UAV motor body 2 assembly device realizes the "screwless" quick installation of the motor body 2 and the propeller through the collaborative design of mechanical linkage and elastic locking, which significantly improves assembly efficiency.
[0070] Working principle: The assembler grasps the rotary handle 24 and drives the screw rod 2 48 to rotate. Because the connecting ring 8 slides on the outer wall of the guide rod 45 through the guide sleeve 44, the connecting ring 8 is guided for sliding. The rotational force of the screw rod 28 acts on the thread raceway of the nut 25. The nut 25 is pushed longitudinally, driving the connecting ring 8 to move longitudinally. When the connecting ring 8 is lifted, a pulling force is applied to the insertion rod 26. When the insertion rod 26 is lifted, the support ring 16 is lifted, and then an extrusion force is applied to the spring 15. The spring 15 is forced to shrink, positioning the upper end support of the spring 15, and the insertion rod 26 slides inside the top block 11. During the process of the insertion rod 26 continuously lifting longitudinally, the insertion rod 26 drives the pull rope 18 to lift, and applies a pulling force to the mounting block 12 through the pull rope 18. The mounting block 12 is supported by the mounting shaft 30 for rotation. When the mounting shaft 30 rotates, it applies an extrusion force to the torsion spring 27. The torsion spring 27 is twisted and contracted under the force, thereby driving the mounting block 12 to rotate, causing the clamping block 29 at one end of the mounting block 12 to flip. The UAV motor body 2 drives the ring 19 to pass through the clamping block 29, and the lower end of the motor body 2 is located inside the assembly seat 5.
[0071] Afterwards, the assembler grasps the rotary handle 24 and drives the screw rod 248 to rotate in the opposite direction, and the connecting ring 8 drops longitudinally. At this time, the spring 15 loses its extrusion force, and the elasticity of the spring 15 itself drives the support ring 16 to drop, thereby driving the insertion rod 26 to drop, and the elastic torsional elastic force of the torsion spring 27 acts on the mounting block 12. The mounting block 12 is forced to rotate in the opposite direction with the mounting shaft 30 as the axis and reset. The mounting block 12 drives the clamping block 29 to be inserted into the inside of the ring groove 23, thereby fixing the collar 19, and then clamping and fixing the motor body 2. When the elastic force of the torsion spring 27 acts on the collar 19, the mounting block 12 is inserted into the inside of the socket 17 through the insertion rod 26, locking the mounting block 12, avoiding the installation of a large number of screws when assembling the motor body 2, reducing the installation time when assembling the drone motor body 2, avoiding the use of additional tools, and convenient installation.
[0072] After the drone motor body 2 is assembled, the mounting sleeve 6 is inserted into the positioning rod 35 through the positioning hole 47, the mounting sleeve 6 is positioned, the pressure strip is pressed, and downward pressure is applied to the stroke rod 38, the latching tooth 36 falls off the slot, and at the same time, an extrusion force is applied to the spring 2 39, the spring 2 39 is forced to shrink, and at the same time, the torsion ring 10 is grasped to drive the screw 1 31 to rotate, the screw 1 31 descends longitudinally inside the screw hole 20, and drives the extrusion cone 32 to apply an extrusion force to the ball 2 28. The extrusion cone 32 applies an increasing extrusion force to the installation during the descending process, and the extrusion force is exerted on the installation through the mounting strip 42 and the limit The ring 4 acts on the spring three 41, and the spring three 41 contracts under the force. The installation strip 42 pressurizes the plug 22 to enter the positioning groove 33 corresponding to the stroke groove 21, and elastically clamps the installation sleeve 6. Then the pressure strip is relaxed, and the spring two 39 drives the clamping block 29 to be inserted into the inside of the clamping groove through its own elasticity, exerting an extrusion force on the torsion ring 10, thereby preventing the torsion ring 10 from rotating. The threaded installation stability of the screw rod 1 31 and the screw hole 20 is improved, and the propeller structure blade 3 of the drone is conveniently installed, avoiding the use of screws and installation tools, and realizing the rapid assembly of the propeller blade 3 structure.
