Description

Technical Field

[0001] This invention relates to an aviation model flight assistance device, specifically an energy station with aviation model flight speed measurement function. Background Technology

[0002] Most existing model aircraft power stations only have basic power output and remote power switch functions. To measure the flight speed of a model aircraft, an additional speed sensor is needed to collect flight data. Speed ​​measurement software is then installed on a computer operating system to analyze the collected data and measure the aircraft's flight speed. This results in a fragmented system with high costs, cumbersome installation, and complex operation. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problem that existing model aircraft energy stations do not have speed measurement functions, and to provide a model aircraft energy station with autonomous speed measurement function that is easy to operate and low in cost.

[0004] The technical solution of the present invention is as follows: The present invention discloses an energy station with built-in flight speed measurement function for aircraft models.

[0005] The energy station includes a main unit, conductive bearings, a traction cable, a remote controller, a bracket, and a base. The main unit is fixed to the base by the bracket and includes a charging circuit, a battery, a voltage regulator circuit, a remote control switch circuit, and a housing. The battery stores externally input electrical energy through the charging circuit and transmits the internally stored electrical energy to the propeller drive motor inside the model aircraft through the voltage regulator circuit, remote control switch circuit, conductive bearing, and traction cable.

[0006] The conductive bearing is a rolling bearing, installed at the top of the bracket. It includes a fixed part fixed to the bracket, a rotating part that secures the traction cable via screws, rivets, or bearing seats and rotates synchronously with it, rolling elements that provide mechanical and electrical connection between the fixed and rotating parts, and a retaining bracket that maintains the relative position of the rolling elements. Using a rolling bearing reduces rotational friction, preventing the rotational friction of the conductive bearing from affecting the flight speed of the model aircraft or causing the traction cable to become entangled on the bracket of the energy station's main unit, and also extends its service life.

[0007] The host computer also includes an aircraft model flight speed measurement module. The aircraft model flight speed measurement module includes a speed sensor, signal processing circuit, display circuit, and sensing object.

[0008] The flight speed sensor for the aircraft model can be Hall effect, photoelectric, inductive, capacitive, mechanical switch, or radar sensing, etc. The speed sensor is mounted on the main unit's housing or bracket at a location corresponding to the rotating part of the conductive bearing, the traction cable, or the connection point between the rotating part of the conductive bearing and the traction cable. The sensing object of the speed sensor is a small magnet fixed to the rotating part of the conductive bearing, or a bearing seat, screw, or other connecting component connecting the rotating part of the conductive bearing and the traction cable. The aircraft model, flying along a circular path under the traction of the traction cable, causes the sensing object to rotate synchronously. The sensing object triggers the speed sensor to output a sensing signal containing the aircraft model's flight speed information. The signal processing circuit processes the sensing signal accordingly and sends the obtained speed value to the display circuit for display.

[0009] The beneficial effects of the present invention are as follows: The aviation model energy station of the present invention, while providing basic functions such as power supply stabilization and remote control output, also realizes the autonomous measurement of the flight speed of the aviation model. It centralizes and optimizes the originally scattered equipment and functions, reduces equipment costs, simplifies installation and operation, and has the technical effect of being simple and efficient.

[0012] The following is in conjunction with the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 The present invention will be described in further detail below.

[0013] Appendix Figure 1 This is a schematic diagram of the circuit principle of the present invention.

[0014] The main unit of the aircraft model energy station includes a charging circuit 11, a battery 12, a voltage regulator circuit 13, and a remote control switch circuit 14; it also includes a speed sensor 15, a signal processing circuit 16, and a display circuit 17 of the aircraft model flight speed measurement module.

[0015] An external power source charges the battery 12 through the charging circuit 11. The electrical energy stored inside the battery 12 is output as a stable voltage through the voltage regulator circuit 13. This voltage is then transmitted to the conductive bearing 2 through the remote control switch circuit 14 controlled by the remote controller 4, and finally to the aircraft model through the traction cable 3 to drive the aircraft model to fly.

[0016] The flight speed sensor 15 of the aircraft model flight speed measurement module indirectly measures the flight speed of the aircraft model by detecting the rotation speed of the conductive bearing 2 that rotates synchronously with the aircraft model and the connection between the conductive bearing 2 and the traction cable 3. The speed sensing signal output by the speed sensor 15 is sent to the signal processing circuit 16. The flight speed value of the aircraft model is obtained by the processing program inside the signal processing circuit 16 and sent to the display circuit 17 for display.

[0017] Appendix Figure 2 Appendix Figure 3 This is a schematic diagram of the structural principle of Embodiment 1 of the present invention.

[0018] In this embodiment, the host 1 and the conductive bearing 2 are mounted as a whole on the top of the bracket 5, and the bracket 5 is mounted on the base 6.

[0019] The electrical energy stored in the battery 12 inside the main unit 1 is regulated and output through the voltage regulator circuit 13, and transmitted to the fixed part 21 of the conductive bearing 2 through the remote control switch circuit 14 controlled by the remote controller 4. Then, it is conducted through the balls inside the conductive bearing 2 to the rotating part 22 of the conductive bearing 2. The rotating part 22 is mechanically and electrically connected to one end of the traction cable 3 through the connector 151. The other end of the traction cable 3 is mechanically and electrically connected to the aircraft model through screws or alligator clips. The electrical energy delivered to the rotating part 22 is transmitted through the traction cable 3 to the motor inside the aircraft model that drives the propeller to rotate, thus driving the aircraft model to fly.

[0020] The flight speed sensor 15 of the aircraft model is fixed to the housing 18 of the main unit 1 at the position corresponding to the rotating part 22 of the conductive bearing 2 and the connector 151 of the traction cable 3. In this embodiment, the speed sensor 15 is a photoelectric sensor. When the aircraft model flies in a circle around the support 5, it drives the traction cable 3, the connector 151, and the rotating part 22 to rotate synchronously. The speed sensor 15 obtains the flight cycle time data of the aircraft model by detecting the rotation period of the connector 151. The signal processing circuit 16 uses the obtained flight cycle time data and the distance data of the flight cycle calculated using the length of the traction cable 3 as the radius to calculate the flight speed value of the aircraft model for each flight cycle through a preset algorithm and transmits it to the display circuit 17 for display.

[0021] Appendix Figure 4 This is a schematic diagram of the structural principle of Embodiment 2 of the present invention.

[0022] In this embodiment, the host 1 is mounted on the base 6, the bracket 5 is mounted on the host 1, and the conductive bearing 2 is mounted on the top of the bracket 5.

[0023] In this embodiment, the conductive bearing 2 is connected to the power output terminal of the remote control switch circuit inside the main unit 1 via a cable through a channel inside the bracket 5. One end of the traction cable 3 is mechanically and electrically connected to the conductive bearing 2 via screws, and the other end is mechanically and electrically connected to the aircraft model via alligator clips, thus providing power to the aircraft model under the control of the remote controller 4.

[0024] The speed sensor 15 is fixed to the upper part of the bracket 5 at the position corresponding to the conductive bearing 2. The obtained speed information is transmitted through a cable to the signal processing circuit inside the host 1 via a channel inside the bracket 5. In this embodiment, the speed sensor is a Hall effect type, which detects speed by detecting a small magnet 152 fixed on the rotating part of the conductive bearing 2.

[0025] Appendix Figure 5 This is a schematic diagram of the circuit principle of Embodiment 2 of the present invention.

[0026] In this embodiment, the flight speed information of the aircraft model is collected by the speed sensor 15, processed by the signal processing circuit 16, and displayed by the display circuit 17.

[0027] The battery 12 obtains electrical energy through the charging circuit 11 and outputs a stable voltage through the voltage regulator circuit 13. One path supplies the main unit, and the other path supplies the model aircraft through the remote control switch circuit 14 controlled by the remote controller 4, the conductive bearing 2, and the traction cable.

[0028] In this embodiment, the inner and outer rings of the conductive bearing 2 serve as the fixed part and the rotating part, respectively. It can be seen that, through corresponding mechanical and circuit adjustments, the inner and outer rings of the conductive bearing 2 can also be adjusted to serve as the rotating part and the fixed part, respectively.
