[0002] A flying car refers to a dual-purpose driving device that can fly in the air or drive on land. As the research and development of flying cars deepens, they become more mature and have gradually met the mature conditions for flying and driving. As the flying component of a flying car, the rotor determines the flight stability of the flying car and has gradually become the main object of research. For example, as shown in a flying car folding rotor structure disclosed on the China Patent Network (publication announcement number CN216423992U), this type of device can conveniently store the flying device by setting its rotor to be foldable and folding its swing arm, and the blades can be folded through the cooperation of the first electromagnet and the second electromagnet, further reducing the space occupancy rate.

[0003] However, the above-mentioned patents and the flying car rotor structures adopted in the existing market still have some shortcomings: the existing method of using independent components to drive the horizontally opposite rotors to fold and retract them is very easy to cause the rotors to be unable to be accurately folded and retracted in one piece due to wear after long-term use, and the safety and stability transmission performance is poor. To this end, those skilled in the art provide a flying car multi-rotor structure to solve the problems raised in the above background technology. Utility Model Content

A transmission motor is arranged in the middle of the shaft rod of the transmission shaft, and transmission worms arranged in positive and reverse directions are symmetrically arranged at both ends of the shaft rod of the transmission shaft. The shaft rods of the two groups of rotating shafts are respectively provided with transmission worm wheels meshing with the transmission worms.

[0010] As a further technical solution of the utility model: a differential gear A is arranged at the output end of the transmission motor, and a differential gear B meshing with the differential gear A is arranged at the middle part of the shaft of the transmission shaft.

[0011] As a further technical solution of the utility model: the locking and positioning mechanism includes a positioning screw, a positioning guide rod and a locking socket installed on the frame bracket from top to bottom inside the locking shell body, and a positioning slide guided by the positioning guide rod is symmetrically arranged on the outer side of the shaft of the positioning screw, and locking pins engaged with the locking socket are symmetrically arranged on both sides of the frame of the two groups of positioning slides.

[0012] As a further technical solution of the utility model: a positioning motor fixed on the locking shell is arranged at one end of the shaft of the positioning screw, and the positioning screw is bounded by a center line, and positive and negative threads matching the two groups of positioning slides are symmetrically arranged on both sides of the center line.

[0015] The utility model provides a flying car multi-rotor structure, which has the following beneficial effects compared with the prior art:

[0016] The flying car rotor structure of the present design is based on a rotary drive combination of a rotary yaw mechanism and a rotary shaft to drive the integrated folding and retracting of multiple sets of frames and wings. While its transmission efficiency is more efficient, the integrated folding and retracting is more precise and modular. When the frame and wing combination is folded and unfolded, based on the locking and positioning of the locking and positioning mechanism, it has good arm force locking performance, ensuring that the folded and unfolded rotor has stable arm force deployment performance and higher safe operation performance.

[0024] See also Figure 1-5 The utility model provides a technical solution for the multi-rotor structure of a flying car: a multi-rotor structure of a flying car, comprising a support platform 1, a rotating shell 3 installed in the middle of the support platform 1, and locking shells 4 symmetrically installed on both sides of the support platform 1. The upper ends of the shells of each group of locking shells 4 are symmetrically provided with rotating seats 5, and the output ends of the two groups of rotating seats 5 are symmetrically connected to the frame 6. The top of the arm of the frame 6 is equipped with a wing 7. By arranging the combination of the frame 6 and the wing 7 in a foldable storage form, it can be unfolded when in use and folded and stored after use, so that the overall occupied space can be reduced and it is convenient for storage.

[0025] The interior of the rotating shell 3 is symmetrically connected to the rotating shaft 2 which is horizontally opposite to the rotating seat 5, and the interior of the rotating shell 3 is provided with a rotating and swaying mechanism for driving the rotating shaft 2. The rotating and swaying mechanism includes a transmission shaft 9 which is connected to the interior of the rotating shell 3 in a direction perpendicular to the shaft of the rotating shaft 2, and a transmission motor 10 is provided in the middle of the shaft of the transmission shaft 9. A differential gear A11 is provided at the output end of the transmission motor 10, and a differential gear B12 which meshes with the differential gear A11 is provided in the middle of the shaft of the transmission shaft 9. The operation of the transmission motor 10 is controlled to drive the differential gear A11 to rotate, and the meshing transmission of the differential gear A11 and the differential gear B12 is utilized to drive the transmission shaft 9 to rotate, which serves as a driving source to drive the horizontally opposite rotating shaft 2 to rotate symmetrically, so that the combination of the frame 6 and the wing 7 is symmetrically folded and retracted.

[0026] The two ends of the shaft of the transmission shaft 9 are symmetrically provided with transmission worms 14 arranged in forward and reverse directions, and the shafts of the two groups of rotating shafts 2 are respectively provided with transmission worm wheels 13 meshing with the transmission worms 14. During the rotation of the transmission shaft 9, the transmission worms 14 arranged in forward and reverse directions at both ends of the shaft are driven to rotate, and the meshing transmission of the transmission worms 14 and the corresponding transmission worm wheels 13 is used to promote the symmetrical rotation of the two groups of rotating shafts 2, and then promote the symmetrical rotation of the output axes of the horizontally opposite rotating seats 5, and the frames 6 and wings 7 on both sides are combined and folded, retracted and unfolded in a symmetrical rotation manner to reduce the occupied space when the flying car is stationary.

[0027] A locking and positioning mechanism opposite to the frame 6 is arranged inside the locking shell 4, and the locking and positioning mechanism includes a positioning screw 18, a positioning guide rod 19 and a locking socket 15 installed on the bracket of the frame 6, which are installed inside the locking shell 4 from top to bottom. A positioning slide 20 guided by the positioning guide rod 19 is symmetrically arranged on the outer side of the shaft of the positioning screw 18, and a positioning motor 22 fixed to the locking shell 4 is arranged at one end of the shaft of the positioning screw 18. The positioning screw 18 is bounded by a center line, and positive and negative threads matching two groups of positioning slides 20 are symmetrically arranged on both sides of the center line. By controlling the operation of the positioning motor 22, the positioning screw 18 is driven to rotate, and the positive and negative threads on the positioning screw 18 are used to push the two groups of positioning slides 20 to slide symmetrically along the direction of the arm of the positioning guide rod 19, and then the corresponding locking components are pushed to slide symmetrically, so as to lock and position the horizontally unfolded frame 6.

[0028] Locking pins 21 that are engaged with the locking sockets 15 are symmetrically arranged on both sides of the two sets of calibration slides 20. The seat surface of the locking socket 15 is provided with locking holes 16 that are opposite to the locking pins 21. When the two sets of calibration slides 20 slide symmetrically, the corresponding locking pins 21 are horizontally inserted into the locking holes 16 of the locking sockets 15 to form a locked positioning state, and the horizontally unfolded frame 6 is locked by arm force to ensure the flight safety and stability of the frame 6 and the wing 7.

[0029] The upper end of the locking shell 4 is symmetrically provided with a flat support seat 8 horizontally opposite to the frame 6 along the rotation direction of the rotating seat 5, and a locking groove 17 compatible with the locking socket 15 is provided in the middle of the support of the flat support seat 8. By utilizing the flat support seat 8 to support the frame 6, the combination of the frame 6 and the wing 7 is stably flattened and plays a role as a horizontal bottom support. By providing the locking groove 17 on the flat support seat 8, it can serve as a deflection displacement space for the locking socket 15.

[0030] The working principle of the utility model is: when the multi-rotor structure of the flying car is installed and used, the rotor structure is installed on the flying car body (as shown in the attached manual). Figure 5 As shown), after installation, the multi-rotor structure is used as its flight component;

[0031] Furthermore, during the installation and use of the multi-rotor structure, when performing flight work, the transmission motor 10 is controlled to work, driving the combined transmission of the differential gear A11 and the differential gear B12, and then driving the transmission shaft 9 to rotate. As a driving source, during the rotation of the transmission shaft 9, the meshing transmission of the transmission worm 14 arranged in positive and reverse directions at both ends of the shaft and the corresponding transmission worm wheel 13 is utilized to drive the two sets of rotating shafts 2 to rotate symmetrically, and then the output shafts of the horizontally opposite rotating seat 5 are driven to rotate symmetrically, and the frames 6 and wings 7 on both sides are combined to be folded and unfolded in a symmetrical rotation manner;

[0032] After the frame 6 and the wing 7 are folded and unfolded, the positioning motor 22 is controlled to work, driving the positioning screw 18 to rotate, and the positive and negative threads on the positioning screw 18 are used to push the two sets of positioning slides 20 to slide symmetrically along the arm direction of the positioning guide rod 19, and the corresponding locking pin 21 is horizontally inserted into the locking socket 16 of the locking socket 15 to form a locked positioning state, and the horizontally unfolded frame 6 is locked by arm force to ensure the flight safety and stability of the frame 6 and the wing 7, and then based on the flight combination of the frame 6 and the wing 7, it is used as a flying component of the flying car;

[0033] After the subsequent flying car completes its flight, the overall space occupied by the flying car can be reduced by folding and stowing the frame 6 and the wings 7 together, making it easier to store.
