[0028] The specific implementation of the present utility model is introduced with reference to the accompanying drawings.

[0029] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of the aircraft. A plurality of telescopic legs 1 are provided at the lower part of the fuselage 101 of the aircraft. The telescopic legs 1 are used to support the aircraft. The extension and contraction of the telescopic legs 1 are used to control the lifting and lowering of the aircraft fuselage 101.

[0030] refer to Figures 1 to 7A lifting mechanism for an aircraft includes a frame 102 and four telescopic legs 1. The telescopic legs 1 are mounted on the frame 102 and arranged toward a support surface supporting the aircraft downward. The lower ends of the telescopic legs 1 are in contact with the support surface. A lifting drive device 2 connected to the telescopic legs 1 is provided on the frame 102. The lifting drive device 2 drives the telescopic legs 1 to extend or shorten relative to the frame 102, thereby driving the fuselage 101 of the aircraft to rise or fall relative to the support surface.

[0031] The aircraft lifting mechanism of the embodiment of the present application supports the aircraft through four telescopic legs 1. The lifting drive device 2 of the frame 102 synchronously drives the four telescopic legs 1. The telescopic legs 1 extend and shorten relative to the frame 102 to realize the lifting and lowering of the aircraft fuselage 101, simulating the lifting and lowering action of the aircraft fuselage 101 for consumers, so that the aircraft has the function of dynamically displaying postures, thereby improving the popularization, viewing and playability of the aircraft.

[0032] In order to drive the telescopic foot 1 to move, in this embodiment, refer to Figures 2 to 6 The lifting drive device 2 includes a driving assembly 3 and a lifting connection 4. The driving assembly 3 is mounted on the frame 102 and is transmission-connected to the lifting connection 4. A slide groove 103 is provided on the frame 102, and the slide groove 103 is communicated with the inner cavity 10 of the telescopic foot 1. The lifting connection 4 is an elastic member and is movably arranged between the slide groove 103 and the inner cavity 10 of the telescopic foot 1. One end of the lifting connection 4 is connected to the telescopic rod 12 of the telescopic foot 1, and the other end of the lifting connection 4 is transmission-connected to the driving assembly 3. The middle part of the lifting connection 4 is bent at the connection between the slide groove 103 and the inner cavity 10 of the telescopic foot 1. The driving assembly 3 drives the lifting connection 4 to move along the slide groove 103 and the inner cavity 10 of the telescopic foot 1 to drive the telescopic foot 1 to extend or shorten.

[0033] It can be understood that with such a configuration, the telescopic foot 1 extends and shortens in the height direction of the aircraft, the drive assembly 3 is arranged along the length direction of the aircraft, and the lifting connection 4 is used as a transmission structure between the drive assembly 3 and the telescopic foot 1. The elastic lifting connection 4 can be bent, thereby facilitating the conversion of the torque of the horizontal drive assembly 3 into a torque in the height direction to drive the telescopic foot 1 to extend or shorten. The transmission structure is simplified, which can facilitate the optimization of other structures of the aircraft.

[0034] In order to guide the lifting connection member 4 to bend, in this embodiment, reference Figure 6 A guide rod 5 is provided at the connection between the slide groove 103 and the inner cavity 10 of the telescopic foot 1. The guide rod 5 and the lifting connection member 4 are perpendicularly arranged to each other and are in sliding contact with the lifting connection member 4.

[0035] It should be further explained that the frame 102 is provided with an installation groove 104 on one side of the slide groove 103, the installation groove 104 is perpendicular to the slide groove 103, the guide rod 5 is stuck in the installation groove 104, and the middle part of the lifting connection member 4 is pressed on the guide rod 5, so that the lifting connection member 4 is bent at the guide rod 5.

[0036] It is understandable that, in this configuration, the lifting connector 4 is an elastic member, and the guide rod 5 is used to guide the lifting connector 4 to bend into an L shape, so that the lifting connector 4 can move between the slide groove 103 and the inner cavity 10 of the telescopic foot 1.

[0037] In order to increase the lifting range of the aircraft, in this embodiment, reference Figure 4 and Figure 5 The telescopic foot 1 includes a foot plate 11, a telescopic rod 12, and a telescopic sleeve 13. The foot plate 11 is in contact with the supporting surface, the lower end of the telescopic rod 12 is connected to the foot plate 11, and the upper end of the telescopic rod 12 is fixed to the lifting connector 4. Multiple telescopic sleeves 13 are sequentially sleeved on the outer circumference direction of the telescopic rod 12 from the inside to the outside, and the outermost telescopic sleeve 13 is fixed to the frame 102.

[0038] It should be further explained that the four telescopic sleeves 13 and the telescopic rod 12 are coaxially arranged, and an inner step surface is provided on the inner wall of each telescopic sleeve 13. The outermost telescopic sleeve 13 is fixed to the frame 102, and the outer walls of the three telescopic sleeves 13 between the outermost telescopic sleeve 13 and the telescopic rod 12 and the outer wall of the telescopic rod 12 are all provided with an outer step surface 14. When the telescopic foot 1 is in the shortened state, the telescopic rod 12 and the three inner telescopic sleeves 13 are retracted into the outermost telescopic sleeve 13, so that the length of the entire telescopic foot 1 is shortened to the length of the outermost telescopic sleeve 13. When the telescopic foot 1 is in the extended state, the outer step surface 14 of the inner telescopic sleeve 13 cooperates with the inner step surface of the adjacent outer telescopic sleeve 13 to limit the telescopic sleeve 13 and the telescopic rod 12 from excessive extension, ensuring that the telescopic sleeve 13 and the telescopic rod 12 will not separate from each other, so that the length of the entire telescopic foot 1 is the sum of the length of the four telescopic sleeves 13 and the telescopic rod 12, ensuring that the telescopic foot 1 can stably support the aircraft fuselage 101.

[0039] It can be understood that, with such a configuration, the shortest length of the telescopic foot 1 is the length of the outermost telescopic sleeve 13, and the longest length of the telescopic foot 1 is the combined length of four telescopic sleeves 13 and one telescopic rod 12. The telescopic range of the telescopic foot 1 is the length of four telescopic sleeves 13, so that the lifting range of the aircraft fuselage 101 is the length of four telescopic sleeves 13.

[0040] In order to drive the lifting connection member 4 to move, in this embodiment, reference Figures 2 to 6The driving assembly 3 includes a motor 31, a reduction gear 32, a transmission rod, a transmission gear 36 and a transmission rack 38 which are sequentially connected. The motor 31 drives the transmission rod and the transmission gear 36 to rotate through the reduction gear 32. The transmission gear 36 drives the transmission rack 38 to move linearly. The transmission rack 38 is arranged parallel to one side of the slide groove 103. The transmission rack 38 is connected to the lifting connection member 4. The transmission rack 38 drives the lifting connection member 4 to move along the slide groove 103 and the inner cavity 10 of the telescopic foot 1.

[0041] It can be understood that with such a configuration, the motor 31 cooperates with the reduction gearbox 32 to increase the torque and reduce the deceleration, thereby controlling the rotation speed within a reasonable range, making the rising and falling speed of the aircraft fuselage 101 controllable, and the synchronous extension and shortening of the four telescopic legs 1 can enable the aircraft fuselage 101 to rise and fall stably, thereby achieving structural simplification.

[0042] In order to better drive the telescopic foot 1 to extend and shorten, in this embodiment, reference Figure 5 and Figure 7 The lifting connecting member 4 is a long tension spring, and a connecting head 15 is provided on the transmission rack 38 and the telescopic rod 12. The connecting head 15 is provided with an external thread 16. The two ends of the long tension spring are respectively sleeved on the connecting head 15 of the transmission rack 38 and the connecting head 15 of the telescopic rod 12, and are fixed with the external thread 16 on the connecting head 15.

[0043] It can be understood that in such a setting, a long tension spring is used as the lifting connection part 4. The long tension spring is a tubular elastic part made of metal. The long tension spring can have a certain axial supporting force, which can smoothly push the telescopic foot 1 to extend. The elastic force of the long tension spring can smoothly pull the telescopic foot 1 to shorten. At the same time, the long tension spring can bend and deform and elastically reset, so that the long tension spring can smoothly bend and slide between the slide groove 103 and the inner cavity 10 of the telescopic foot 1.

[0044] In order to stably guide the movement of the transmission rack 38 and the lifting connection member 4, in this embodiment, reference Figure 5 and Figure 6 The transmission rack 38 is provided with a straight tooth portion 381 and a sliding portion 382 in parallel. The straight tooth portion 381 is engaged with the transmission gear 36 for transmission. The sliding portion 382 is arranged in the slide groove 103. The connecting head 15 is provided on the side of the sliding portion 382 close to the telescopic foot 1.

[0045] It can be understood that, with such a setting, the slide groove 103 serves as a guiding structure, the lifting connection member 4 can be embedded in the slide groove 103, the transmission rack 38 is connected to the long tension spring through the connecting head 15, and the sliding part 382 of the transmission rack 38 is set in the slide groove 103, and the transmission rack 38 and the long tension spring are guided together through the slide groove 103 to ensure that the transmission rack 38 can.

[0046] In order to simplify the driving component 3, in this embodiment, reference Figure 4 Two transmission racks 38 are provided on both sides of the transmission gear 36 to synchronously drive the two telescopic legs 1 to extend or shorten.

[0047] It is understandable that, with such an arrangement, the two transmission racks 38 are driven by the transmission gear 36, which simplifies the transmission structure and makes the structure of the drive assembly 3 streamlined, so that it can be better arranged on the frame 102 for easy assembly.

[0048] In order to drive the four telescopic legs 1 to extend or shorten together, in this embodiment, reference Figures 2 to 4 The transmission rod is divided into a first transmission rod 33 and a second transmission rod 34. The first transmission rod 33 is installed on the reduction box 32. The two ends of the first transmission rod 33 are respectively connected to the two second transmission rods 34 through two sets of first gear plates 35. The second transmission rod 34 is connected to the second gear plate 37 coaxially arranged on one side of the transmission gear 36.

[0049] It can be understood that, with such a configuration, the power of the reduction gearbox 32 is distributed to the two second transmission rods 34 through the first transmission rod 33, and the two second transmission rods 34 transmit the power to the four transmission racks 38 through the two transmission gears 36, so that the power of the motor 31 is synchronously transmitted to the four transmission racks 38, and at the same time drives the four telescopic legs 1 to extend or shorten.

[0050] In order to stably transmit the power of the second transmission rod 34 to the transmission rack 38, in this embodiment, Figure 5 The transmission gear 36 and the second gear plate 37 are fixed by a transmission shaft 361. A connecting plate 362 is sleeved on the middle of the transmission shaft 361. The transmission shaft 361 is slidably connected to the connecting plate 362, and the connecting plate 362 is connected to the frame 102.

[0051] It can be understood that, with such an arrangement, the transmission gear 36 and the second gear plate 37 rotate synchronously through the transmission shaft 361, and the transmission shaft 361 is stably connected to the frame 102 through the connecting plate 362, so that the transmission shaft 361, the transmission gear 36 and the second gear plate 37 can rotate stably on the frame 102, so that the power of the second transmission rod 34 is stably transmitted to the transmission gear 36 through the second gear plate 37, the transmission shaft 361, and the transmission gear 36.

[0052] It should be further explained that the transmission rack 38 is made of a flexible plastic material, which is soft and can be bent. In order to match the appearance of the aircraft, the slide groove 103 of the frame 102 is provided with a curved section. The flexible transmission rack 38 can move well along the curved slide groove 103, so that the lifting mechanism is well compatible with the appearance of the aircraft.

[0053] The embodiment of the present application supports the aircraft through four telescopic legs 1, and pushes and pulls the telescopic legs 1 through long elastically deformable tension springs to achieve the extension and shortening of the telescopic legs 1. The motor 31 of the lifting drive device 2 increases the torque through the reduction gear 32, so that the transmission rack 38 has sufficient power to push and pull the long tension spring. The power of the motor 31 is synchronously transmitted to the four transmission racks 38 through the transmission rod and the transmission gear 36, so as to synchronously drive the four telescopic legs 1 to extend and shorten relative to the frame 102, so as to achieve the lifting and lowering of the aircraft fuselage 101, simulate the lifting and lowering action of the aircraft fuselage 101 for consumers, and enable the aircraft to have the function of dynamically displaying postures, thereby improving the popularization, viewing and playability of the aircraft toy model.

[0054] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
