Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flying cars, in particular to a land-air dual-mode unmanned exchange cabin flying car. BACKGROUND

[0002] The car can fly into the sky, which is the next goal pursued by people since the invention of the car. With the development of cities, the traffic pressure of major cities in the world continues to increase, and the severe reality prompts people to strengthen the research on flying cars. It can be predicted that the future mode of travel will change from the current "car-airplane-car" to "car mode-airplane mode-car mode", that is, a kind of transportation tool completes point-to-point travel, which is "flying car".

[0003] In the design and application of the land-air dual-mode unmanned exchange cabin flying car, the propeller blade is the core component to realize the flight function, and its running state directly affects the overall performance and safety of the flying car. During flight, the propeller blade is in a high-speed rotating state, at which time the blade surface produces intense friction with the air, and there is also relative motion friction between internal mechanical components such as the transmission shaft and the bearing sleeve. These friction processes not only consume a lot of power, resulting in the inability of the motor output power to be effectively converted into flight lift, reducing flight efficiency, but also generate a large amount of friction heat. If the friction parts cannot be lubricated in time and effectively, the friction resistance will increase significantly, further aggravating the power loss, and at the same time, the high temperature will accelerate the wear of the mechanical components, shorten their service life, and even cause mechanical failure, posing a serious threat to flight safety.

[0004] Therefore, it is urgent to improve the land-air dual-mode unmanned exchange cabin flying car to solve the above-mentioned problems. SUMMARY

[0009] Furthermore, there are multiple infusion holes, which are arranged in a ring shape inside the annular tube. There are two sets of bearing seats and two sets of annular tubes, and a connecting tube is fixedly connected between the two sets of bearing seats and annular tubes.

[0010] Furthermore, the end of the extraction tube away from the piston cylinder is fixedly connected to the liquid storage tank, and a check valve is elastically hinged inside the extraction tube.

[0013] Furthermore, there are two sets of the mounting housing, propeller blades, and drive shaft. The two sets of mounting housing, propeller blades, and drive shafts are symmetrically distributed inside the power box and extend to its surface.

[0014] Furthermore, the outer diameter of the stirring rod is adapted to the inner diameter of the liquid storage tank, a limiting groove is provided at the bottom of the toothed block, and a limiting block adapted to the limiting groove is fixedly connected to the top of the liquid storage tank.

[0018] Compared with the prior art, the present invention provides a land-air dual-mode unmanned exchange cabin flying car, which has the following beneficial effects:

[0019] 1. This invention utilizes a dual-end motor. One end drives the propeller blades to rotate via a worm gear and worm wheel, while the other end drives an eccentric wheel. A connecting rod pulls the piston rod, causing the piston plate to slide back and forth within the piston cylinder. Lubricating fluid is drawn from the reservoir and delivered to an annular pipe via a delivery pipe.

Through the meshing transmission between the toothed block and the gear, the stirring rod is driven to rotate inside the storage tank, continuously stirring the lubricating liquid and preventing sedimentation and stratification due to static standing. At the same time, the cooperation between the limiting groove and the limiting block ensures stable sliding of the toothed block, guarantees uniform stirring, and maintains good lubrication and heat dissipation performance of the lubricating liquid.

[0021] 3. This invention uses a geared motor to drive the power box and propeller blades to adjust their angles via a rotating base, thus meeting the requirements for flight attitude control. The transmission mechanism simultaneously drives the propeller to rotate, delivers and agitates the lubricating fluid, achieving functional integration, ensuring continuous and reliable lubrication, and comprehensively guaranteeing the operational safety and efficiency of the propeller blades.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 6 This embodiment discloses a dual-mode unmanned exchange cabin flying car, comprising a flying car body 1 and a flight power device 2 disposed outside the flying car body 1. The flight power device 2 includes a fixed frame 21, a reduction motor 22, a rotating seat 23, a power box 24, a mounting shell 25, a propeller blade 26, a bearing seat 27, and a drive shaft 28. The power box 24 is externally provided with a self-lubricating fluid delivery structure 3 extending into the bearing seat 27. The power box 24 is also externally provided with a stirring structure 4 that works in conjunction with the fluid delivery structure 3. The power box 24 is further provided with a transmission mechanism 5 that is linked to both the fluid delivery structure 3 and the stirring structure 4. Multiple sets of flight power devices 2 are arranged sequentially outside the flying car body 1.

[0031] The mounting frame 21 is fixedly connected to the exterior of the flying car body 1, the geared motor 22 is fixedly mounted on the exterior of the mounting frame 21, the rotating seat 23 is fixedly connected to the output shaft of the geared motor 22, and the power box 24 is fixedly connected to the exterior of the rotating seat 23. By driving the rotating seat 23 through the geared motor 22, the angles of the power box 24 and the propeller blades 26 can be flexibly adjusted. This satisfies the attitude control requirements during aerial turning and ascent / descend, and also allows for adjustment of the propeller blades 26 to a suitable angle during land-based storage, adapting to dual-mode land-air applications.

[0032] Specifically, the mounting housing 25 is fixedly connected to the top of the power box 24, the propeller blade 26 is rotatably connected to the inside of the mounting housing 25, and the drive shaft 28 is fixedly connected to the bottom of the propeller blade 26 and extends into the inside of the bearing housing 27. The drive shaft 28 is also rotatably connected to the inside of the bearing housing 27. By setting up the mounting housing 25, dust, small particles, and other impurities in the air can be isolated, preventing them from adhering to the surface of the propeller blade 26 and affecting the rotation efficiency. At the same time, it prevents the propeller blade 26 from causing collision damage to external components when rotating at high speed. The cooperation between the drive shaft 28 and the bearing housing 27 provides a stable transmission path for the high-speed rotation of the propeller blade 26, reduces radial runout during rotation, and lowers mechanical vibration noise.

[0033] It should be noted that there are two sets of mounting housing 25, propeller blade 26 and drive shaft 28. The two sets of mounting housing 25, propeller blade 26 and drive shaft 28 are symmetrically distributed inside the power box 24 and extend to its surface.

[0034] In this embodiment, the infusion structure 3 includes a piston cylinder 31 fixedly connected to the outside of the power box 24 and an annular tube 35 fixedly connected to the inside of the bearing seat 27. An infusion hole 36 is provided inside the annular tube 35. A piston plate 32 is slidably connected inside the piston cylinder 31. A piston rod 38 extending to the outside of the piston cylinder 31 is fixedly connected to the outside of the piston plate 32. An infusion tube 34 is fixedly connected to one side of the annular tube 35 and the piston cylinder 31, and an extraction tube 33 is fixedly connected to the other side of the piston cylinder 31. By sliding the piston plate 32 inside the piston cylinder 31, lubricating fluid is drawn from the storage tank 41 through the extraction tube 33 and then transported to the annular tube 35 via the infusion tube 34. This avoids excessive waste or insufficient lubrication failure. The infusion hole 36 inside the annular tube 35 allows the lubricating fluid to be directly delivered to the inside of the bearing seat 27, precisely acting on the friction surface between the drive shaft 28 and the bearing seat 27, thus improving lubrication efficiency.

[0035] The infusion holes 36 are multiple, and the multiple infusion holes 36 are arranged in a ring shape inside the annular tube 35. There are two sets of bearing seats 27 and two sets of annular tubes 35. The two sets of bearing seats 27 and annular tubes 35 are fixedly connected by a connecting tube 37.

[0036] Specifically, the end of the extraction tube 33 furthest from the piston cylinder 31 is fixedly connected to the reservoir 41, and a check valve is elastically hinged inside the extraction tube 33. By setting the check valve, the lubricating fluid is prevented from flowing back to the reservoir 41 through the extraction tube 33 when the piston cylinder 31 pushes the lubricating fluid, ensuring that all the lubricating fluid is delivered to the bearing housing 27 through the delivery tube 34, thus improving the delivery efficiency. At the same time, the check valve can prevent impurities in the bearing housing 27 from entering the reservoir 41 through the extraction tube 33, avoiding contamination of the overall lubricating fluid and extending the service life of the lubricating fluid.

[0037] In this embodiment, the stirring structure 4 includes a liquid storage tank 41 fixedly connected to the outside of the power box 24 and a stirring rod 42 rotatably connected to the inside of the liquid storage tank 41. A gear 43 is fixedly connected to the top of the stirring rod 42, and a toothed block 44 is meshed with the outside of the gear 43. A transmission rod 45 is fixedly connected to the outside of the toothed block 44. The reciprocating sliding of the toothed block 44 drives the gear 43 to rotate, converting linear motion into rotational motion of the stirring rod 42. This results in high transmission efficiency and enables synchronous start and stop of lubricant delivery and stirring.

[0038] The outer diameter of the stirring rod 42 is adapted to the inner diameter of the liquid storage tank 41. The bottom of the toothed block 44 is provided with a limiting groove 46. The top of the liquid storage tank 41 is fixedly connected with a limiting block adapted to the limiting groove 46. The limiting groove 46 and the limiting block are slidably connected.

[0039] In this embodiment, the transmission mechanism 5 includes a double-ended motor 51 fixedly installed outside the power box 24 and a worm gear 53 fixedly installed outside one of the transmission shafts 28. A worm 52 that meshes with the worm gear 53 is fixedly connected to one output shaft of the double-ended motor 51, and an eccentric wheel 56 is fixedly connected to the other output shaft of the double-ended motor 51. A pull rod 57 is hinged to the outside of the eccentric wheel 56, and the pull rod 57 is hinged to the end of the piston rod 38 away from the piston plate 32.

[0040] The end of the transmission rod 45 away from the toothed block 44 and the end of the pull rod 57 away from the eccentric wheel 56 are hinged together, and the toothed block 44 is reciprocally slidably connected to the surface of the liquid storage tank 41 through the transmission rod 45.

[0041] Specifically, the transmission mechanism 5 also includes synchronous pulleys 54 that are fixedly installed on the outside of the two transmission shafts 28 respectively, and the two synchronous pulleys 54 are externally connected to anti-slip belts 55.

[0042] The working principle of the above embodiments is as follows:

[0043] During the switching and operation of the flying car body 1 in air or on land mode, its flight power equipment 2 plays a crucial role. When the flying car body 1 starts, the dual-end motor 51 begins to work. One end of its output shaft drives the worm gear 52 to rotate, which meshes with the worm wheel 53, causing the transmission shaft 28 to rotate. This, in turn, causes the propeller blades 26 to rotate at high speed, providing power for flight. At the same time, the other end of the dual-end motor 51 drives the eccentric wheel 56 to rotate. The eccentric wheel 56 drives the piston rod 38 to reciprocate through the pull rod 57, causing the piston plate 32 to slide inside the piston cylinder 31. When the piston plate 32 slides, it draws lubricating fluid from the reservoir 41 through the extraction pipe 33. The check valve in the extraction pipe 33 prevents the lubricating fluid from flowing back. The lubricating fluid is then transported through the infusion pipe 34 to the annular pipe 35, and then through multiple ring-shaped distributions. The infusion port 36 precisely delivers fluid to the inside of the bearing housing 27, providing lubrication for the friction surface between the drive shaft 28 and the bearing housing 27. When the pull rod 57 reciprocates, it also drives the toothed block 44 to slide back and forth on the surface of the storage tank 41 through the drive rod 45. Because the toothed block 44 meshes with the gear 43 at the top of the stirring rod 42, it converts the linear motion into the rotational motion of the stirring rod 42, stirring the lubricant in the storage tank 41 and ensuring the quality of the lubricant. In addition, the synchronous pulleys 54 on the outside of the two drive shafts 28 are connected by the anti-slip belt 55, so that the two propeller blades 26 rotate synchronously to ensure flight stability. The geared motor 22 drives the rotating seat 23 to rotate, which can flexibly adjust the angle of the power box 24 and the propeller blades 26 to meet the needs of aerial turning, ascent and descent attitude control and land storage.

[0044] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
