Description

Tail rotor structure of remote control helicopter

This creation relates to a tail rotor assembly for a remotely controlled helicopter, especially a tail rotor assembly that can be implemented with three rotors.

According to the current design, the tail rotor designs of remote-control helicopters are mostly two-rotor designs, but this kind of structure makes it difficult for the remote-control helicopter to perform stable suspension or straight flight. On the other hand, the tail rotor structure of today's remote-control helicopters uses a single point to push and pull a push ring, so that the push ring drives other structures to control the state of the rotor, but this embodiment will concentrate the stress a little and make the structure easily damaged.

The main purpose of this creation is to provide a tail rotor structure that can be implemented with three rotors.

Another purpose of this creation is to solve the problem that the conventional push-pull structure is easily damaged by conventional push-pull structure.

In order to achieve the above object, the present invention provides a tail rotor structure of a remote-control helicopter, which comprises a tail rotor drive shaft, an adapter seat, a three-rotor clamp seat, and a push-pull assembly. The joint seat is connected to the tail fin drive shaft at the center and has three mounting parts, and the three mounting parts are arranged on the joint seat in a manner of equal 360 degrees. The three-rotor clip holders are respectively disposed in one of the three mounting portions. First, the three-rotor clip holders are respectively provided with a connecting arm on the same side. The push-pull assembly includes a set of connecting bases provided on the fin drive shaft and having three bridge arms, three of which are respectively connected to one of the connecting arms and one of the bridge arm transmission parts, one is connected to the connecting base and is sleeved on A pushing ring on the fin drive shaft, a set of support stands provided on the fin drive shaft, a pushing arm pivotally arranged on the supporting stand and connected with the pushing ring, the pushing ring having a ring provided by the pushing ring The groove has two pushing rods respectively arranged in the groove.

In one embodiment, the two push rods are located on the same axis.

In one embodiment, the ends of the three transmission members on the same side are constructed as a triangle.

In one embodiment, the ends of the push arms diverge to define a space for providing the push ring therein, and the two push rods face the space respectively.

Through the above technical solution of this creation, compared with the conventional one, it has the following characteristics: This tail rotor structure is implemented with three rotors, so that the remote-controlled helicopter can be hovered statically more stably or fly in a stable straight line, and the tail of the remote-controlled helicopter is improved. The sharpness of the rudder turning left and right. In addition, in this creation, the push arm and the push-pull ring are implemented in a double push-pull structure, which can specifically disperse the stress that each push rod bears on the push-pull ring, so that the push ring can be more smoothly Was pushed and increased the overall balance.

The detailed description and technical content of this creation are described below with reference to the drawings: please refer to FIG. 1 to FIG. 5, FIG. 1 is a schematic structural diagram of an embodiment of the creation; FIG. 2 is an exploded schematic diagram of an embodiment of the creation; 3 is a schematic diagram of a partial structure of a push-pull component according to an embodiment of the present invention; FIG. 4 is a schematic plan view of an embodiment of the present invention; FIG. 5 is a schematic diagram of an embodiment of the present invention. As shown in the figure, this creation provides a tail rotor structure 100. The tail rotor structure 100 is assembled on the tail of a remote-controlled helicopter 200 and is linked by a rotation driving structure (not shown in the figure) to generate rotation. The tail rotor structure 100 includes a tail drive shaft 10 connected to the rotary driving structure, an adapter seat 20 connected to the tail drive shaft 10 at a center portion, and three rotor clip seats 30 respectively connected to the adapter seat 20, And a push-pull component 40. More specifically, the connecting base 20 has three mounting portions 201, and the three mounting portions 201 are disposed on the connecting base 20 in a manner of equal 360 degrees. In one embodiment, each of the mounting portions 201 may be a hole. In addition, the three-rotor clip holders 30 are respectively disposed corresponding to one of the three mounting portions 201, and each of the three-rotor clip holders 30 is provided with a rotor arrangement therein. Further, the three-rotor clamp base 30 is provided with a connecting arm 301 on the same side, for example, one of the connecting arms 301 is provided on the right side of each of the rotor clamp bases 30. With this, the present invention enables the remote-controlled helicopter 200 to be implemented with a three-tailed rotor, so that the remote-controlled helicopter 200 can be hovered statically more stably or fly straightly. In addition, the implementation of a three-tailed rotor can improve the sharpness of the remote control helicopter's 200 rudders in left and right turns.

Please refer to FIG. 1 to FIG. 4 again. The push-pull assembly 40 includes a set of connection bases 401 provided on the tail shaft 10 and having three bridge arms 402. Three of them are connected to one of the connection arms 301 and One of the transmission members 403 of the bridge arm 402, one of the pushing rings 404 connected to the connecting seat 401 and sleeved on the fin drive shaft 10, a set of support 405 provided on the fin drive shaft 10, a pivot A pushing arm 406 is mounted on the supporting platform 405 and is connected to the pushing ring 404. Further, the three connecting arms 402 can also be arranged on the connecting base 401 in a manner of 360-degree division, so that the endpoints of the three transmission members 403 on the same side are constructed to form a triangle 51. In addition, the support platform 405 is provided with the pushing arm 406 pivoted on, and the pushing arm 406 is allowed to swing relative to the support platform 405. In the embodiment of the present invention, the pushing ring 404 has a groove 407 provided in the pushing ring 404, and the pushing arm 406 has two pushing rods 408 respectively disposed in the groove 407. Further, the two push rods 408 are located on the same axis 50, as shown in FIG. 3. In addition, the end of the pushing arm 406 is divided to define a space 409 for providing the pushing ring 404 therein, and the two pushing rods 408 face the space 409 and extend into the groove 407, respectively. In order to form a double push-pull, the stress generated when pushing and pulling the push ring 404 is dispersed through the two push-pull rods 408, so that the push ring 404 can be pushed more smoothly, and the overall balance is increased at the same time.

On the other hand, during the implementation process, the push arm 406 is controlled by a push-pull control (not shown in the figure), and when swinging relative to the support base 405, the push arm 406 will push the push-pull with the two push-pull rods 408 Ring 404, so that the push-pull ring 404 drives the connecting seat 401 to be displaced relative to the rear wing drive shaft 10, and during the displacement of the connecting seat 401, each of the transmission members 403 will drive each of the rotor clamp seats 30 to generate a deviation Pendulum, changing the state of each rotor.

The above has made a detailed description of this creation, but the above is only one of the preferred embodiments of this creation. When the scope of implementation of this creation cannot be limited by this, that is, the equality made according to the scope of patent application for this new model Changes and modifications should still be covered by the patent for this new model.
