Description

Technical Field

[0001] This utility model relates to a shock-absorbing and insulating fixing structure, and in particular to a shock-absorbing and insulating fixing structure for a vertical take-off and landing aircraft motor, belonging to the field of aerospace technology. Background Technology

[0002] Electric vertical takeoff and landing (EVTOL) aircraft, also known as electric vertical takeoff and landing (eVTOL) aircraft, are motor-driven aircraft capable of vertical takeoff and landing without a runway. The motors are powered by electric energy sources, including batteries and fuel cells. EVTOL aircraft can be classified along two dimensions: Based on operating mode, they can be divided into manned and unmanned categories. Based on configuration, they can be divided into winged and wingless categories. Wingless aircraft are primarily multi-rotor aircraft, while winged aircraft can be further divided into compound wing aircraft and tiltrotor aircraft, the main difference being the methods of generating vertical lift and forward thrust.

[0003] However, when using existing technology, in severe weather conditions such as strong winds and convective winds, the longitudinal damping and fixing structure of the motor lacks sufficient lateral damping and buffering, which easily accelerates the wear of the rubber dampers inside the longitudinal damping and fixing structure of the motor. The durability of the motor damping structure still needs to be improved. Therefore, a damping and insulating fixing structure for vertical take-off and landing aircraft motors is proposed. Summary of the Invention

[0004] In view of this, the present invention provides a shock-absorbing and insulating fixing structure for a vertical take-off and landing aircraft motor to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model is as follows: a shock-absorbing and insulating fixing structure for a vertical take-off and landing aircraft motor, including a motor, a lateral shock-absorbing mechanism, a longitudinal shock-absorbing mechanism, a propeller fixedly installed on the motor, and an insulating plate fixedly connected to the bottom of the motor.

[0006] The transverse damping mechanism includes a horizontal plate movably connected to an insulating plate. Two fixed blocks are fixedly connected to one side of the horizontal plate. A rod is fixedly connected to the adjacent side of the two fixed blocks. A shock absorber is fixedly connected to one side of the fixed blocks. A base plate is fixedly connected to the other end of the shock absorber. A vertical plate is fixedly connected to one side of the base plate. A collar is slidably connected to the rod. A spring is fixedly fitted on the rod. The two ends of the spring are fixedly connected to the collar and the fixed blocks, respectively. A movable plate is rotatably connected to the collar. The other side of the movable plate is rotatably connected to the vertical plate.

[0007] More preferably, the longitudinal damping mechanism includes a fixed plate fixedly connected to one side of the base plate, a rubber pad is movably installed inside the fixed plate, an inner bushing is embedded inside the rubber pad, a single-headed bolt is slidably connected inside the inner bushing, and one end of the single-headed bolt is movably connected to an insulating plate.

[0008] More preferably, the number of movable plates is two, the two movable plates are symmetrically distributed on the upright plate, and the angle between the adjacent side of the two movable plates and the upright plate is greater than ninety degrees.

[0009] More preferably, a first threaded hole is provided on one side of the insulating plate, and a first through groove adapted to the first threaded hole is provided on the horizontal plate, and the horizontal plate is connected to the insulating plate by screw threads.

[0010] More preferably, the insulating plate has six second through slots, and both sides of the insulating plate are fixedly connected with sleeves of a number that match the number of second through slots, and the inner diameter of the sleeves is larger than the diameter of the second through slots.

[0011] More preferably, the rubber pads are in two sets, with six rubber pads in each set and adapted to the sleeve. The outer surfaces of both sets of rubber pads are attached to the inner sidewall of the sleeve. A second threaded hole adapted to a single-headed bolt is provided on one side of the insulating plate, and one end of the single-headed bolt is threaded onto the insulating plate through the second threaded hole.

[0012] More preferably, a gasket is installed on one side of the rubber pads near the insulating plate and on one side of the other set of rubber pads, and the outer diameter of the gasket is smaller than the inner diameter of the sleeve.

[0013] More preferably, the fixing plate has a number of through holes, and a double-ended bolt is slidably connected to the inner wall of the through hole. A fixing bushing is movably fitted on the double-ended bolt, and one end of the double-ended bolt extends through the through hole to the outside of the fixing plate and is threadedly connected to a nut.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] This invention utilizes a transverse damping mechanism on a fixed plate. In strong winds or convective winds, this mechanism causes the insulation plate and the fixed plate on the motor to vibrate, altering the gap between them. This, in turn, causes the damper to deform and compresses the spring on the movable plate. This provides double-layer damping and buffering against external forces, preventing excessive stress on the longitudinal damping mechanism between the motor and the fixed plate on the insulation plate. This reduces wear and improves the overall structural durability.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, this utility model embodiment provides a vibration damping and insulation fixing structure for a vertical take-off and landing aircraft motor, including a motor 1, a lateral vibration damping mechanism 2, a longitudinal vibration damping mechanism 3, a propeller 11 fixedly installed on the motor 1, and an insulation plate 10 fixedly connected to the bottom of the motor 1.

[0028] In one embodiment, to facilitate the installation and disassembly of the transverse damping mechanism 2, the transverse damping mechanism 2 includes a horizontal plate 23 movably connected to the insulating plate 10. To facilitate the fixing of the shock absorber 21, two fixing blocks 22 are fixedly connected to one side of the horizontal plate 23. A rod 24 is fixedly connected to the adjacent side of the two fixing blocks 22. The shock absorber 21 is fixedly connected to one side of the fixing blocks 22. To achieve double-layer damping by driving the movable plate 26 to compress the spring 28 when the shock absorber 21 deforms, a base plate 20 is fixedly connected to the other end of the shock absorber 21. A vertical plate 25 is fixedly connected to one side of the base plate 20. A collar 27 is slidably connected to the rod 24. A spring 28 is fixedly fitted on the rod 24. The two ends of the spring 28 are fixedly connected to the collar 27 and the fixing block 22, respectively. A movable plate 26 is rotatably connected to the collar 27. The other side of the movable plate 26 is rotatably connected to the vertical plate 25.

[0029] In one embodiment, in order to facilitate the installation and disassembly of the longitudinal damping of the motor 1, the longitudinal damping mechanism 3 includes a fixed plate 13 fixedly connected to one side of the base plate 20. A rubber pad 30 is movably installed inside the fixed plate 13. An inner bushing 35 is embedded inside the rubber pad 30. A single-headed bolt 37 is slidably connected inside the inner bushing 35. One end of the single-headed bolt 37 is movably connected to the insulating plate 10.

[0030] In one embodiment, in order to facilitate the symmetrical distribution of the two movable plates 26 to always compress the spring 28 for shock absorption when subjected to external force, there are two movable plates 26, which are symmetrically distributed on the vertical plate 25, and the angle between the adjacent side of the two movable plates 26 and the vertical plate 25 is greater than 90 degrees; in order to facilitate the fixing of the transverse shock absorption mechanism 2 by screws, a first threaded hole 201 is provided on one side of the insulating plate 10, and a first through groove 29 adapted to the first threaded hole 201 is provided on the horizontal plate 23, and the horizontal plate 23 is threadedly connected to the insulating plate 10 by screws.

[0031] In one embodiment, to facilitate the installation of the rubber pad 30, the insulating plate 10 has six second through slots 32. Sleeves 31, matching the number of second through slots 32, are fixedly connected to both sides of the insulating plate 10, with the inner diameter of the sleeves 31 being larger than the diameter of the second through slots 32. To facilitate fixing the rubber pad 30 to the insulating plate 10, there are two sets of rubber pads 30, each set consisting of six rubber pads that match the sleeves 31. The outer surfaces of both sets of rubber pads 30 are attached to the inner sidewall of the sleeves 31. A second threaded hole 36, matching the single-ended bolt 37, is provided on one side of the insulating plate 10. One end of the single-ended bolt 37 is threaded onto the insulating plate 10 through the second threaded hole 36.

[0032] In one embodiment, to facilitate the fastening of the rubber pads 30, a gasket 34 is installed on one side of one set of rubber pads 30 near the insulating plate 10 and on one side of another set of rubber pads 30. The outer diameter of the gasket 34 is smaller than the inner diameter of the sleeve 31. To facilitate the fixing of the motor 1 to the machine body via the fixing plate 13, a number of through holes 14 are provided on the fixing plate 13. A double-ended bolt 12 is slidably connected to the inner side wall of the through hole 14. A fixing bushing 15 is movably fitted on the double-ended bolt 12. One end of the double-ended bolt 12 extends through the through hole 14 to the outside of the fixing plate 13 and is threadedly connected to the nut.

[0033] In operation, the operator inserts the rubber pad 30 into the sleeve 31, then inserts the inner liner 35 into the two sets of rubber pads 30. Simultaneously, the gasket 34 is placed on the rubber pads 30, and the fixing plate 13 is fixed to the insulation plate 10 of the motor 1 using a single-headed bolt 37. The lateral shock absorber is then fixed to the insulation plate 10 using screws. Furthermore, it can be fixed to the fuselage using double-headed bolts 12. Therefore, during flight, when the aircraft motor 1 is subjected to strong winds or convective winds, the insulation plate 10 and the fixing plate 13 on the motor 1 can be kept in place. The vibration of plate 13 changes the gap between them, which in turn causes the shock absorber 21 to deform, driving the vertical plate 25 to push the movable plate 26. At the same time, the movable plate 26 drives the collar 27 to compress the spring 28, storing and dissipating the external force. The shock absorber 21 provides double-layer shock absorption and buffering. The transverse shock absorption mechanism 2 on the fixed plate 13 prevents the motor 1 on the insulating plate 10 from bearing excessive stress between the longitudinal shock absorption fixation and the fixed plate 13, thereby reducing wear and improving the overall structural durability.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
