Description

Technical Field

[0001] This application relates to the field of model aircraft, and more particularly to a model aircraft handle. Background Technology

[0002] Model aircraft remote controllers are typically used to control the flight of model aircraft. They generate channel values ​​through joysticks or dials, which are then transmitted to the model aircraft via a wireless link. These values ​​then drive the servos or ESCs, thereby controlling the model aircraft's movement.

[0003] When model airplanes are flying in the city, there may be situations where people, trees, buildings, or other objects block the signals emitted by the model airplane's handle, causing the model airplane to lose control during flight and thus affecting its flight.

[0004] The antennas of existing model aircraft handles are usually fixedly mounted on the handle and cannot be adjusted according to the flight direction and angle of the model aircraft. They can only be manually aligned or adjusted to adjust the overall angle of the handle, thereby adjusting the antenna of the model aircraft, which is inconvenient for the use of model aircraft handles.

[0057] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0058] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0059] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0060] An embodiment of this application provides a model aircraft handle 100, comprising:

[0061] The shell 110 has a hemispherical groove 110a.

[0062] The first drive assembly 120 is installed in the hemispherical groove 110a.

[0063] The second drive component 130 is installed in the hemispherical groove 110a and is perpendicular to the movement direction of the first drive component 120.

[0064] The antenna 140 has a connecting ball 140a at one end, which is installed in the hemispherical groove 110a and is tumbledly connected to the first driving component 120 and the second driving component 130.

[0065] The first driving component 120 and / or the second driving component 130 move to drive the connecting ball portion 140a to rotate around the center of the hemispherical groove 110a, thereby changing the angle between the antenna 140 and the housing 110.

[0066] Please refer to Figures 1-9 In this embodiment, the first drive assembly 120 and the second drive assembly 130 are both disposed in the hemispherical groove 110a and form a rolling connection with the connecting ball part 140a (for example, by a roller, ball, or coated rolling element contacting the spherical surface). The movement directions of the two drive assemblies are perpendicular to each other, forming two decoupled orthogonal degrees of freedom.

[0067] First, a rolling drive is applied to the connecting ball portion 140a along a first tangential direction, and then a rolling drive is applied along a second tangential direction perpendicular to it.

[0068] During operation, the first drive assembly 120 and / or the second drive assembly 130 move under control. The rolling engagement between them and the connecting ball part 140a converts the driving torque into the rotation of the ball part around the center of the hemispherical groove 110a, thereby continuously changing the spatial angle of the antenna 140 relative to the housing 110 (which can correspondingly realize independent adjustment of azimuth and pitch).

[0069] By providing a spherical rotary joint and orthogonal drive inside the handle, the antenna 140 can adjust its orientation in real time without changing the grip posture, so as to adapt to the rapid changes in the position and attitude of the model aircraft in the urban environment.

[0070] It can actively align with the direction of the model aircraft and optimize polarization matching, thereby reducing link fading caused by obstruction and multipath, improving the stability and effective distance of the control link, and reducing the risk of packet loss and loss of control.

[0071] In at least one embodiment of this application, the housing 110 is provided with a first mounting groove 110c, which is located on the inner wall of the hemispherical groove 110a.

[0072] The first driving component 120 includes:

[0073] The first drive motor 121 has one end located in the first mounting groove 110c and the other end extending into the hemispherical groove 110a.

[0074] The first rolling wheel 122 is disposed in the hemispherical groove 110a and is fixedly connected to the output end of the first drive motor 121. The outer peripheral surface of the first rolling wheel 122 is in rolling connection with the connecting ball part 140a.

[0075] Please refer to Figures 1-9 In this embodiment, during operation, the control module 171 drives the first drive motor 121 to rotate, the outer peripheral surface of the first rolling wheel 122 is rolledly connected to the connecting ball part 140a and applies a tangential driving torque to the spherical surface, so that the connecting ball part 140a rotates around the center of the hemispherical groove 110a along the first degree of freedom, thereby driving the antenna 140 to change the angle relative to the housing 110.

[0076] The first drive component 120 can realize real-time tracking of the model aircraft's direction changes. Combined with another orthogonal degree of freedom, it can realize two-axis linkage adjustment, making it easier for the antenna 140 to avoid obstructions such as people, trees or buildings in complex urban scenes and optimize polarization matching, thereby reducing the risk of packet loss and loss of control.

[0077] In at least one embodiment of this application, the housing 110 is provided with a second mounting groove 110d, which is located on the inner wall of the hemispherical groove 110a.

[0078] The second drive component 130 includes:

[0079] The second drive motor 131 has one end located in the second mounting groove 110d and the other end extending into the hemispherical groove 110a.

[0080] The second rolling wheel 132 is disposed in the hemispherical groove 110a and is fixedly connected to the output end of the second drive motor 131. The outer peripheral surface of the second rolling wheel 132 is in rolling connection with the connecting ball part 140a.

[0081] Please refer to Figures 1-9 In this embodiment, during operation, the control module 171 issues a command according to the target angle to drive the second drive motor 131 to rotate. The second rolling wheel 132 applies a tangential driving torque to the connecting ball part 140a in a direction orthogonal to the first rolling wheel 122, so that the connecting ball part 140a rotates in the second degree of freedom relative to the center of the hemispherical groove 110a. This cooperates with the first drive assembly 120 to realize independent and continuous angle adjustment of the antenna 140 relative to the housing 110 in two mutually perpendicular directions.

[0082] The antenna's adjustable range of 140° has been expanded and its angular resolution and follow-up speed have been improved, making it easier to align with targets and optimize polarization matching in complex environments. This significantly reduces the risk of link fading, packet loss and loss of control caused by obstruction and multipath.

[0083] In at least one embodiment of this application, the model aircraft handle 100 further includes:

[0084] The magnetic component 150 is installed inside the housing 110 and coupled to the connecting ball portion 140a.

[0085] In at least one embodiment of this application, a connecting hole 110b is provided on the central axis of the hemispherical groove 110a.

[0086] The model aircraft handle 100 also includes:

[0087] A magnetic sheet 160 is installed in the connecting hole 110b, and the magnetic component 150 is magnetically coupled to the connecting ball portion 140a through the magnetic sheet 160.

[0088] Please refer to Figures 1-9 In this embodiment, a through or blind hole is provided on the back of the hemispherical groove 110a of the housing 110 along its central axis as a connecting hole 110b. A magnetic sheet 160 (preferably a soft magnetic material, such as silicon steel sheet or permalloy) is press-fitted or bonded in the connecting hole 110b. A magnetic component 150 is installed in the housing 110. The magnetic component 150 can be a permanent magnet (such as neodymium iron boron with a back iron) or a controllable electromagnet.

[0089] A back iron / magnetic base can be provided between the magnetic component 150 and the magnetic sheet 160. The connecting ball portion 140a can be made entirely of a magnetizable material (such as stainless steel or low carbon steel) or have annular or sheet-shaped magnetic inserts embedded inside the ball. The magnetic component 150 directs the magnetic flux to one side of the hemispherical groove 110a via the magnetic sheet 160, forming a magnetic coupling relationship with the connecting ball portion 140a, generating an attractive force at the center of the sphere.

[0090] The magnetic component 150 provides a stable normal preload, ensuring a reliable rolling connection between the first and second rolling wheels 132 and the connecting ball 140a and suppressing slippage, thereby improving the orientation accuracy of the antenna 140.

[0091] The magnetic conductor 160 confines the magnetic circuit to the central axis of the sphere, reducing magnetic interference to surrounding components.

[0092] In at least one embodiment of this application, the antenna 140 further includes a signal line 140b that extends into the housing 110 and is electrically connected to an electronic component 170 inside the housing 110.

[0093] Please refer to Figures 1-9In this embodiment, the antenna 140 is configured as a rod structure with a built-in radio frequency signal line 140b. One end of the signal line 140b is electrically connected to the radiator of the antenna 140, and the other end extends into the housing 110 in the form of a flexible coaxial line (such as a micro coaxial line) and is electrically connected to the electronic components 170 (such as radio frequency transmitters, transceiver modules, power amplifiers, matching networks, or main control boards) inside the housing 110.

[0094] The housing 110 forms a lead wire guide groove and an annular avoidance step on the outer periphery of the hemispherical groove 110a that are tangent to or concentric with the groove opening. After the signal wire 140b is laid attached to the guide groove, it enters the interior of the housing 110 through an independent wire hole set at a position radially offset from the axis of the sphere. A sealing sleeve and stress relief component are installed at the hole opening.

[0095] In at least one embodiment of this application, the antenna 140 is mounted on the outer side of the housing 110 and disposed opposite the opening of the hemispherical groove 110a.

[0096] Please refer to Figures 1-9 In this embodiment, the opening of the hemispherical groove 110a faces the mounting direction of the antenna 140. The connecting ball 140a rotates around the center of the ball in the groove under the orthogonal rolling drive of the first and second driving components 130, which drives the antenna 140 located outside the opening to change its angle synchronously.

[0097] During operation, the control module 171 drives two sets of rolling wheels to generate tangential torque along two orthogonal directions, causing the connecting ball part 140a to rotate around the center of the ball. The outer antenna 140 then continuously adjusts its orientation in both azimuth and pitch degrees of freedom, achieving active alignment of the model aircraft with changes in relative azimuth without altering the overall attitude of the handle.

[0098] In at least one embodiment of this application, the model aircraft handle 100 further includes:

[0099] Electronic component 170 is disposed inside the housing 110 and includes a control module 171 and a power supply module 172.

[0100] In at least one embodiment of this application, the model aircraft handle 100 further includes:

[0101] A control joystick 180 is mounted on the housing 110 and electrically connected to the control module 171.

[0102] In at least one embodiment of this application, the model aircraft handle 100 further includes:

[0103] The display screen 190 is mounted on the housing 110 and is electrically connected to the control module 171.

[0104] Please refer to Figures 1-9In this embodiment, the control module 171 may be composed of a microcontroller (MCU) / SoC, a dual-channel motor driver, an RF interface and I / O circuit, a non-volatile memory, etc.

[0105] The control module 171 is electrically connected to the first and second drive motors and performs open-loop and closed-loop drive on the two rolling wheels according to the target direction, so that the connecting ball part 140a rotates around the center of the hemispherical groove 110a, so that the antenna 140 faces the model aircraft.

[0106] The control module 171 is connected to the radio frequency section, the antenna 140 feeder interface, the power monitoring and alarm circuit, and manages the angle control and remote control link status in a unified manner.

[0107] The control joystick 180 is located on the outer surface of the housing 110 and is electrically connected to the control module 171. It is used to output flight channel commands and can also be used as input for the mode, gain, and speed of the antenna 140.

[0108] The display screen 190 is mounted on the housing 110 and electrically connected to the control module 171. It displays in real-time link quality (e.g., RSSI / LQ), the current azimuth, elevation angle, drive status (motor duty / temperature), power supply, and alarm information of the antenna 140. It also provides menu items for zero-position calibration, range testing, and limit setting. During operation, the control module 171 calculates the target direction based on the joystick and switch inputs and (optionally) telemetry information, and outputs coordinated speed and torque commands to the two motor drives, enabling the antenna 140 to continuously adjust in two degrees of freedom.

[0109] Simultaneously monitor battery level and temperature rise, and reduce drive power or alert the user when necessary to ensure stable coordination between the directional mechanism and the RF link.

[0110] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
