[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] In the attached diagram, all identical reference numerals refer to the same components.

[0026] like Figure 1-5 As shown, this utility model provides a blade structure for a micro flying car, including a walking base 1, a storage module 101 and a flight frame 102. A support member 103 is installed between the flight frame 102 and the walking base 1. A flat plate 2 is installed on the upper and lower sides of the flight frame 102. Front rotating blocks 3 are installed on both sides of the front end of the flat plate 2, and rear rotating blocks 4 are installed on both sides of the rear end of the flat plate 2. The front rotating blocks 3 and the rear rotating blocks 4 are staggered on the same plane.

[0027] Both the front rotating block 3 and the rear rotating block 4 are equipped with extension rods 5. The end of the extension rod 5 is provided with a mounting base 6. The top of the mounting base 6 is equipped with a rotating module 7. The top of the rotating module 7 is provided with a fixing member 8. The top of the fixing member 8 is equipped with a clamping member 9. Both ends of the clamping member 9 are fixed with flying blades 10. The flying blades 10 are used to fix to both ends of the clamping member 9 or to rotate around the end of the clamping member 9. The front rotating block 3 and the rear rotating block 4 are used to fold the extension rod 5 to the middle of the flat plate 2.

[0028] The surface of the flight frame 102 includes an electronic control module and a wireless connection module. The electronic control module is an MCU microcontroller or an STM32 microcontroller, and the wireless connection module is a cellular network or a Bluetooth module.

[0029] Its structure is mainly based on the walking base 1, the storage module 101, and the flight frame 102, such as Figure 1 As shown, the walking base 1 is equipped with a motor and tires, and the flight frame 102 forms the conversion between flight and ground movement. The storage module 101 is mainly used to transport or store the target object to the destination. Because the conventional structure is large when unfolded, it is not convenient to carry or store. Therefore, a foldable front rotating block 3 and a rear rotating block 4 are provided. Together with the clamping part 9, the rotating module 7 can be folded to both sides of the flight frame 102 to complete the storage function.

[0030] In a further embodiment, such as Figure 2 As shown, the clamping member 9 includes an upper crossbar 901, a lower crossbar 902, and a connecting screw 903. The flight blade 10 is located between the upper crossbar 901 and the lower crossbar 902, and is connected to the surface of the lower crossbar 902 by the connecting screw 903. The bottom of the lower crossbar 902 is connected to the rotating module 7 via a fixing member 8. A fastening screw 904 is installed on the top of the clamping member 9. The fastening screw 904 is used to fix the flight blade 10 to the clamping member 9. The fastening screw 904 is slidably sleeved with the upper crossbar 901, and the fastening screw 904 is threadedly connected to the lower crossbar 902. In this embodiment, the clamping member 9 mainly completes the clamping of the flight blade through the upper crossbar 901 and the lower crossbar 902. The clamping of the blade 10 is based on the connecting screw 903 passing through the flight blade 10 to the lower crossbar 902, allowing the flight blade 10 to rotate around the connecting screw 903, thus satisfying the function of circumferential rotation of the flight blade 10 around the end of the clamping member 9, that is, realizing the function of storage; when the flight blade 10 is used for flight, it is only necessary to rotate the fastening screw 904 downwards to make the upper crossbar 901 and the lower crossbar 902 clamp and fix it; if further simplification is required, the connecting screw 903 can be directly connected to the upper crossbar 901 and the lower crossbar 902 respectively, and when the flight blade 10 needs to rotate circumferentially, only the connecting screw 903 needs to be loosened, and the fastening screw 904 is only used as a secondary fixing structure.

[0031] In a further embodiment, such as Figure 5 As shown, the rotating module 7 is a drive motor, which is used to drive the rotation of the flight blade 10; the rotating module 7 and the extension rod 5 are fixedly connected by the mounting base 6; the upper side flat plate 2 has a limiting groove 11, which is used to limit the extension rod 5; the upper surfaces of the front rotating block 3 and the rear rotating block 4 are both provided with spring buckles 12, which are structurally corresponding to the limiting grooves 11; conventionally, the front rotating block 3 and the rear rotating block 4 can be provided with damping structures to prevent their own rotation. In order to improve their stability, spring buckles 12 are provided on the top of the front rotating block 3 and the rear rotating block 4, such as Figure 1As shown, the spring buckle 12 is used in conjunction with the limiting groove 11. In order to cooperate with the storage structure, the limiting groove 11 can be set in different positions on the flat plate 2 to achieve the limiting function after the front rotating block 3 and the rear rotating block 4 rotate, so that the extension rod 5 can be fixed and limited when stored and unfolded.

[0032] In a further embodiment, such as Figure 3-4 As shown, the planar plate 2 includes a front plate 201, a tail plate 202, and a middle plate 203, wherein the area of ​​the front plate 201 is smaller than that of the tail plate 202, and the connection between the middle plate 203 and the tail plate 202 is set at a right angle; the rotation direction of the front rotating blocks 3 is all towards the tail plate 202, and the rotation direction of the rear rotating blocks 4 is all towards the front plate 201; the flight blades 10 rotate via connecting screws 903, and the rotation direction of the flight blades 10 is towards the front plate 201; as shown... Figure 3 As can be seen in its unfolded state, during normal flight or use, the extension rod 5 extends outward from the four corners of the flat plate 2; when retracted, first rotate the front rotating block 3 until it forms the shape shown. Figure 4 In form, Figure 4 The planar plate 2 in the middle is the lower planar plate 2, and the fastening screw 904 is loosened so that the flight blade 10 faces the front plate 201. At this time, the end of the extension rod 5 of the front rotating block 3 is located at the right angle connection between the middle plate 203 and the tail plate 202, and the height of the rotating module 7 is above the upper planar plate 2; the rear rotating block 4 is then retracted as follows. Figure 4 The mode is covered on the outside, and the flight blade 10 also faces the front plate 201. This allows the rotating module 7 to be offset to the left and right, while the overall structure can also form a triangular structure facing forward. When the ground walking function is used alone, it can create a wind-breaking effect and reduce the wind resistance of the blade.

[0033] In summary, this utility model improves the micro flying car by allowing the upper flying frame structure to be deployed and retracted depending on the usage method. When carried or when only the ground kinetic energy structure is used, the flying frame can be retracted to the surface to reduce the overall space occupied, while the resulting triangular structure can also create a wind-breaking effect.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
