[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0033] Example 1

[0034] See also Figure 1-5 The technical solution of an ultra-fine steel wire rolling transmission rod structure provided in this embodiment includes the following:

[0035] Servo 1 installed on the aerospace model;

[0036] The transmission rod assembly 2 comprises an ultra-fine steel wire 21 and a sleeve 22, wherein the sleeve 22 is sleeved around the ultra-fine steel wire 21;

[0037] The control surface connection assembly 3 includes an adjustment member 31 and a bracket 32, wherein the bracket 32 ​​is connected to the bottom of the control surface 4 on the aerospace model, and the adjustment member 31 is connected to the bracket 32;

[0038] Among them, one end of the ultra-fine steel wire 21 is connected to the steering gear 1, and the other end is connected to the adjusting member 31; the steering gear 1 drives the ultra-fine steel wire 21 to move forward and backward in the sleeve 22, so as to drive the rudder surface 4 to work through the rudder surface connecting assembly 3.

[0039] Specifically, in the model aircraft, the main purpose of providing the tooth pattern on the steel wire connecting the servo 1 and the rudder surface 4 is to increase the friction between the steel wire and the connection points between the servo 1 and the rudder surface 4, so as to ensure more stable and reliable transmission. Therefore, the ultra-fine steel wire 21 in the present design is a tooth-containing steel wire, and the diameter range of the ultra-fine steel wire 21 is 0.5mm to 0.7mm.

[0040] Preferably, the sleeve 22 is set as a transparent PP hose mainly for the following considerations: 1. The PP hose has sufficient flexibility to allow the ultra-fine steel wire 21 to move freely forward and backward in the tube. This ensures that when the steering gear 1 controls the control surface 4, the ultra-fine steel wire 21 can smoothly transmit the action without being hindered by the tube wall. 2. The PP hose provides a protective environment for the ultra-fine steel wire 21 to prevent it from being hit or rubbed by external objects during flight. This helps to reduce the wear of the ultra-fine steel wire 21 and extend its service life. 3. The PP hose provides a clear path for the ultra-fine steel wire 21 to ensure that it does not deviate from the predetermined direction during movement. This helps to maintain the correct connection between the ultra-fine steel wire 21 and the steering gear 1 and the control surface 4, ensuring that the control surface 4 can accurately respond to the control of the steering gear 1. 4. The PP hose also has certain insulation properties, which can prevent the electric sparks generated by the steel wire due to friction or other reasons from causing potential danger to the aircraft model. 5. The PP hose can also reduce the noise and vibration generated by the ultra-fine steel wire 21 during movement to a certain extent, and improve the overall flight performance of the aircraft model.

[0041] Specifically, the servo 1 is a screw servo 1, and the servo 1 includes a frame 11, a servo motor 12, a driving gear 13, a driven gear 14, a screw frame 15, a screw 16, and a wire mounting frame 17 for mounting the ultra-fine steel wire 21;

[0042] The servo motor 12 and the screw rod frame 15 are installed on the frame 11 in parallel with each other. The screw rod 16 is rotatably arranged in the screw rod frame 15 . The wire mounting frame 17 is sleeved on the screw rod 16 and is threadedly connected with the screw rod 16 .

[0043] In a specific implementation, the steel wire mounting frame 17 is provided with a mounting hole for the ultra-fine steel wire 21 , and the ultra-fine steel wire 21 can be passed through and bent and then fixed on the steel wire mounting frame 17 , or can be fixed by other fixing methods.

[0044] Specifically, a driven gear 14 is fixedly provided on one end of the lead screw 16 away from the ultra-fine steel wire 21 , and a driving gear 13 is provided on one end of the servo motor 12 corresponding to the driven gear 14 , and the driving gear 13 is meshingly connected with the driven gear 14 .

[0045] In a specific implementation, the servo motor 12 drives the driving gear 13 to rotate, the driving gear 13 drives the driven gear 14 to rotate, the driven gear 14 drives the screw rod 16 to rotate in the screw rod frame 15, and the screw rod drives the wire mounting frame 17 to drive the ultra-fine steel wire 21 to move forward and backward through the spiral transmission action with the wire mounting frame 17.

[0046] In a specific implementation, the rotation angle of the servo 1 can be controlled by changing the duty cycle of the control signal. To achieve the reverse rotation of the driving gear 13, the polarity of the control signal needs to be reversed. In this way, the servo motor 12 will adjust its rotation direction according to the new control signal, thereby driving the driving gear 13 to rotate forward or reverse, so as to drive the wire mounting frame 17 to move forward and backward to adjust the ultra-fine steel wire 21.

[0047] Specifically, the adjusting member 31 is a metal ball head buckle, which includes a ball head and a buckle seat that are matched and connected to each other. The buckle seat is fixedly connected to the end of the ultra-fine steel wire 21 that is not connected to the servo 1, and the ball head is connected to the bracket 32.

[0048] Preferably, the design of the adjustment member 31 allows the ball head to rotate freely in the socket or allows the socket to rotate finely around the ball head, but limits its movement in a linear direction, ensuring that the stretching or compression of the ultra-fine steel wire 21 can be accurately converted into the deflection movement of the rudder surface 4, reducing the friction and resistance caused by angle mismatch and improving the overall performance of the system.

[0049] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
