Description

Fixed wing model aeroplane and model ship convenient to take off and land training

Technical Field

Background

The aviation model, as the name implies, is a recoverable model made by imitating the appearance of an aircraft, belongs to an aerospace model and is an unmanned aircraft for sports.

Modern aviation model motions are divided into five categories of free flight, line manipulation, radio remote control, simulation and electric. The manner of the pressing force is divided into: piston engines, jet engines, rubber band powered model aircraft, unpowered model gliders, and the like. The maximum lift area of the aeromodel is 500 square decimeters; maximum weight 25 kg; the maximum working volume of the piston engine is 250 milliliters. The model airplane is generally the same as a manned airplane and mainly comprises six parts of wings, tail wings, a fuselage, landing gear, an engine and a control system. The control system is used for controlling the model airplane by receiving signals sent by the radio remote controller.

The traditional model airplane radio remote controller comprises two rocking bars, wherein one rocking bar transversely slides to control the model airplane rudder and longitudinally slides to control the elevator; the other rocker slides left and right to control aileron and longitudinally slides to control throttle. Both rockers are proportional channels (i.e., steering engine rotation angle is related to rocker sliding angle). The rocker for controlling the throttle can not automatically return to the middle, and is a fixed type proportional channel. The rest rockers can automatically return to the middle. The sensors in the 4 directions are all common potentiometers. The switch channel is also included, only 2 states-on and off. The remote control typically includes a transmitting antenna that transmits the modulated carrier signal. And part of the remote controllers are also provided with liquid crystal display screens for displaying related parameters such as signal emission frequency, residual electric quantity and the like of the remote controllers.

The workflow of a traditional model-of-flight radio remote control is: the sensing potentiometer in the remote controller converts the motion into a continuously-changing voltage signal, the voltage signal is processed into a specific instruction signal by the built-in coding circuit, and then the specific instruction signal is processed by the carrier wave of the built-in high-frequency signal transmitting head, and the radio signal is transmitted by the antenna. The receiver carries out signal conversion, amplification and interference removal on the received radio signal, then outputs a pulse signal which is adaptive to the steering engine through decoding processing, and sends the pulse signal into the steering engine. And the steering engine executes actions to control the control surface of the aircraft to finish the control. The traditional model airplane radio remote controller is a relatively professional remote control device, and when an airplane is remotely controlled, two thumbs are usually required to simultaneously operate two operation handles of the remote controller, so that the operation is inconvenient, and the using hand feeling is poor; the user can be mastered by professional training; because the arm of force of the handle is shorter, when the finger moves a certain distance, the angle change is large, and the accurate control is not easy.

The utility model provides a fixed wing model aeroplane and model ship convenient to take off and land training, includes the remote controller, the remote controller includes flexible stop device 1, flexible stop device 1 is used for carrying out segmental touch feedback to the slip of rocker.

The current common model airplane remote controller comprises two rocking bars and four proportional channels, wherein the four proportional channels are common sensing potentiometers, the sensing potentiometers convert the actions of the rocking bars into continuously-changed voltage signals, the continuously-changed voltage signals are processed into specific instruction signals through an in-machine coding circuit, and then the specific instruction signals are processed through an in-machine high-frequency signal transmitting head carrier wave and transmitted out through an antenna. The receiver carries out signal conversion, amplification and interference removal on the received radio signal, then outputs a pulse signal which is adaptive to the steering engine through decoding processing, and sends the pulse signal into the steering engine. The steering engine executes actions to control the control surface of the aircraft to finish the control, namely the sliding angle of the rocker controls the rotating angle of the steering engine. One of the rockers transversely slides to control the rudder of the model airplane and longitudinally slides to control the elevator; the other rocker slides left and right to control aileron and longitudinally slides to control throttle.

The traditional model airplane radio remote controller is a relatively professional remote control device, when a remote control airplane is controlled, two thumbs are usually required to operate two operation rockers of the remote controller at the same time, when fingers move a certain distance, the angle change is large, and especially a beginner is not easy to control accurately.

In order to facilitate the beginner to easily experience certain specific operations, such as landing, taking off and turning lamp operation, the rocker corresponds to the operation position. In this embodiment, a flexible limiting device 1 is disposed at a position opposite to the proportional channel through which the rocker passes, so as to provide resistance to the operation of the rocker, so that the sliding of the rocker is stagnant, and the sliding of the rocker is subjected to segmental tactile feedback.

As shown in fig. 2, the remote controller includes a flexible limiting device 1, the flexible limiting device 1 may include a pulling piece 2, the pulling piece 2 may be made of a metal sheet or a rubber material that can be elastically deformed, and the pulling piece 2 may be in various shapes such as rectangle, square, ellipse, etc. So as to provide sliding resistance of the rocker. The plectrum 2 can flexibly select various positions. Exemplary, one of these is: the plectrum 2 attach in the remote controller casing surface, with the relative setting of the proportional passageway of rocker operation sets up single or a plurality of plectrum 2 promptly along rocker operation passageway unilateral or two sides, and when the rocker passed through plectrum 2, the plectrum 2 was extruded to the direction of operation, and plectrum 2 takes place elastic deformation under the extrusion force effect of rocker, and the resistance that the plectrum 2 was overcome to the rocker passes through, and plectrum 2 resumes the original state. So that the rocker has a stagnant feel when passing through each plectrum 2, and has a sectionally stopped touch when passing through each plectrum 2. So as to realize the sliding and the stagnation of the rocker and enable the sliding of the rocker to carry out segmental touch feedback. The plectrum 2 is attached to the outer surface of the remote controller shell, the existing remote controller is not required to be changed, and the effect of segmental touch feedback of sliding of the rocker can be generated only by attaching the plectrum 2 to the upper surface of the remote controller shell.

In the flexible limiting device 1 provided by the above example, due to the installation mode of attaching the plectrum 2 to the outer surface of the remote controller shell, the plectrum 2 is on the side of the rocker running channel, the hands of the model airplane students are easy to contact with the plectrum 2 when the rocker is operated, and the hands of the model airplane students are easy to be injured when the plectrum 2 is restored to the original state. Thus, for example, the dial 2 may be attached to the inner wall of the casing of the remote controller, or a connection board may be disposed inside the remote controller, and the connection board may be fixed to the inner wall of the remote controller, where the dial 2 is attached to the connection board, and disposed opposite to the proportional channel in which the rocker operates, that is, a single or multiple dials 2 are disposed along one side or both sides of the rocker operating channel. When the rocker passes through the plectrum 2, the plectrum 2 is extruded in the running direction, the plectrum 2 is elastically deformed under the extrusion force action of the rocker, the resistance of the rocker to the deformation of the plectrum 2 is overcome, and the plectrum 2 is restored to the original state. So that the rocker has a stagnant feel when passing through each plectrum 2, and has a sectionally stopped touch when passing through each plectrum 2. So as to realize the sliding and the stagnation of the rocker and enable the sliding of the rocker to carry out segmental touch feedback. The plectrum 2 is arranged in the remote controller shell, can prevent the hands of the model airplane students from contacting with the plectrum 2, and can prevent the hands of the model airplane students from being injured when the plectrum 2 is restored to the original state.

The flexible limiting device 1 provided by the above example is used for attaching the pulling sheet 2 to the inner wall of the remote controller shell, a cavity is needed to be arranged in the remote controller shell to accommodate the pulling sheet 2 or the connecting plate, a part of remote controllers cannot be applicable due to small internal space, the internal structure of the original remote controllers is needed to be changed, and the pulling sheet 2 can only be embedded into the remote controllers in advance in the production process of the remote controllers, so that the universality is poor.

Therefore, the flexible limiting device 1 can be arranged to comprise a limiting device shell 8 and a poking piece 2, the limiting device shell 8 accommodates the remote controller, a cross lead groove is formed in the surface of the limiting device shell 8, and the cross lead groove is aligned with a proportional channel of rocker operation. The poking piece 2 is made of elastically deformable metal sheet or rubber material. The poking piece 2 is arranged in the limiting device shell 8 and attached to the inner wall of the limiting device shell 8. The plectrum 2 with the proportional channel of rocker operation sets up relatively, sets up single or a plurality of plectrum 2 along rocker operation passageway unilateral or two sides, and when the rocker passed through plectrum 2, extrusion plectrum 2 in the direction of operation, plectrum 2 takes place elastic deformation under the exogenic action, and the resistance of plectrum 2 deformation is overcome to the rocker and is passed through, plectrum 2 reconversion. So that the rocker has a stagnant feel when passing through each of the paddles 2, and has a sectionally stopped touch when passing through a plurality of paddles 2. So as to realize the sliding and the stagnation of the rocker and enable the sliding of the rocker to carry out segmental touch feedback. The plectrum 2 is arranged in the shell 8 of the limiting device, so that the contact between the hands of an operator and the plectrum 2 can be prevented, and the hands of the model airplane students can be prevented from being injured when the plectrum 2 is restored; meanwhile, the remote controller is suitable for most remote controllers and has strong universality.

The use of the paddle 2 can achieve a sense of touch that causes a segmental pause in operation, but the paddle 2 has a stress concentration in a deformation region during deformation. In the long-time use process, the poking piece 2 may deform or break under the impact force of the rocker, so that the use is affected. Therefore, this embodiment further provides another implementation manner of the limiting device, as shown in fig. 3, the flexible limiting device 1 may include a guide plate 3, where the guide plate 3 is a rubber plate that can be elastically deformed, the guide plate 3 is attached to the outer surface of the remote controller housing, the guide plate 3 is provided with a concave-convex curved surface on one side near the rocker, and the concave-convex curved surface of the guide plate 3 is disposed opposite to the proportional channel in which the rocker operates, that is, disposed along a single side or two sides of the rocker operating channel. When the rocker passes through the convex points of the concave-convex curved surfaces, the guide plate 3 is extruded in the running direction, the guide plate 3 is elastically deformed under the action of external force, the rocker passes through the convex points against the deformation resistance of the guide plate 3, and the guide plate 3 is restored to the original state. Therefore, the rocker has a stagnant feel when passing through each convex point, and has a tactility of section pause when passing through a plurality of convex points. Compared with the poking piece 2, the deformation area of the concave-convex curved surface of the guide plate 3 is at the convex point position, the stress is dispersed on the maximum section of the convex surface, and the stress concentration does not exist, so that the service life of the guide plate 3 is longer under the action of the impact force of the rocker. On the other hand, the rocker slides in the channel, namely slides along the concave-convex curved surface of the guide plate 3, the curved surface plays a guiding role, the process that the rocker passes through the convex points is stable, the required force is gradually increased, the impact force received by the rocker is small, and the service life of the rocker is prolonged.

Specifically, the guide plate 3 may be disposed at various positions with respect to the remote controller housing according to the need. The flexible limiting device 1 includes a guide plate 3, the guide plate 3 is attached to the inner surface of the remote controller shell or fixed to the inner side surface of the remote controller shell, the guide plate 3 is provided with a concave-convex curved surface near one side of the rocker, the concave-convex curved surface of the guide plate 3 is opposite to the proportional channel of the rocker running, that is, the concave-convex curved surface of the guide plate 3 is arranged along one side or two sides of the rocker running channel, when the rocker passes through the convex points of the concave-convex curved surface, the guide plate 3 is extruded in the running direction, the guide plate 3 is elastically deformed under the action of external force, the resistance of the deformation of the guide plate 3 is overcome, and the guide plate 3 is restored to the original state. Therefore, the rocker has a stagnant feel when passing through each convex point, and has a tactility of section pause when passing through a plurality of convex points. When the guide plate 3 is attached to the outer surface of the remote controller shell, the guide plate covers one side or two sides of the rocker running channel, when the remote controller is used, the position of the concave-convex curved surface of the guide plate 3 from the center of the rocker running channel cannot be observed, if the position of the guide plate 3 deviates, the resistance of the rocker is suddenly increased when the rocker passes through the convex points, and the rocker is difficult to pass through; or reduced resistance and reduced stagnant feel. In this example, the guide plate 3 is attached to the inner surface of the remote controller casing, so that the position of the concave-convex curved surface of the guide plate 3 relative to the center of the rocker running channel can be observed in the rocker running process, and the uniform and stable resistance provided by the convex points of the guide plate 3 in the rocker running process is ensured.

The flexible limiting device 1 provided by the above example is characterized in that the guide plate 3 is installed in the remote controller shell, the guide plate 3 needs to be accommodated in the remote controller shell by a cavity, a part of the remote controller cannot be applied due to small internal space, and the scheme can only be embedded into the remote controller in advance in the production process of the remote controller, so that the universality is poor.

In another embodiment, the flexible limiting device 1 comprises a limiting device housing 8 and a guide plate 3, the limiting device housing 8 accommodates the remote controller, a cross lead groove is formed in the surface of the limiting device housing 8, and the cross lead groove is aligned with the proportional channel of the rocker operation. The guide plate 3 is a rubber plate which can be elastically deformed, and the guide plate 3 is attached to the inner wall of the limiting device shell 8. The deflector 3 is being close to one side of the rocker is equipped with unsmooth curved surface, unsmooth curved surface of deflector 3 with the proportional passageway of rocker operation sets up relatively, promptly along rocker operation passageway unilateral or two sides set up, and the rocker passes through when unsmooth curved surface's bump, the deflector 3 is extruded in the direction of operation, and deflector 3 takes place elastic deformation under the exogenic action, and the resistance that the deflector 3 warp is overcome to the rocker passes through, and deflector 3 resumes the original state. Therefore, the rocker has a stagnant feel when passing through each convex point, and has a tactility of section pause when passing through a plurality of convex points. The guide plate 3 is attached to the inner wall of the limiting device shell 8, so that the universality of the flexible limiting device 1 is met, the position of the concave-convex curved surface of the guide plate 3 relative to the center of the rocker running channel can be observed, and the uniform and stable resistance provided by the convex points of the guide plate 3 in the rocker running process is ensured.

Because there are different types of remote controllers, and there are the same type of remote controllers for different types of drive mechanisms, the throttle ratio is also different. The flexible limiting device 1 provided above cannot be applied to all types of remote controllers for fixed wing aeromodelling. Therefore, the invention also provides a fixed wing model for easy take-off and landing training, which comprises a remote controller, wherein the remote controller comprises a flexible limiting device 1, the flexible limiting device 1 can comprise a splice 4 and an elastomer, the elastomer is made of rubber which can be elastically deformed, and is fixed on the splice 4; or the flexible limiting device 1 can comprise a splicing piece 4 and a poking piece 2, wherein the poking piece 2 is attached to the side face of the splicing piece 4. One of the tiles 4 may be provided with one or more elastic bodies or dials 2, the tile 4 and the remote control housing comprise a mateable plug structure for securing, for example a plug pin is provided on the tile 4, and a plug hole 10 is provided in the corresponding remote control housing. The splice 4 is fixedly connected with the remote controller shell through a splicing structure, so that the elastic bodies are arranged opposite to the proportional channels operated by the rockers, namely, a single or multiple elastic bodies are arranged on one side or two sides of the rocker operating channels, when the rockers pass through the elastic bodies, the elastic bodies are extruded in the operating direction, the elastic bodies are elastically deformed under the action of external force, the rockers overcome the resistance of the elastic bodies to deform and pass through, and the elastic bodies are restored to be original, so that the rockers have a stagnant feeling when passing through the elastic bodies of each splice 4, and have a segmental pause touch when passing through the multiple elastic bodies. For controlling different types of driving mechanisms using the same remote controller or using different types of remote controllers, a flexible limiting device 1 is provided, which comprises elastic bodies at different positions because the sliding angles of the rocking bars in the proportional channels of the remote controllers are different. Because the elastomer can be adjusted in position on the remote controller shell at any time through the splicing and inserting piece 4, the flexibility is strong, and the remote controller is suitable for various remote controllers.

Although the above technical solution can flexibly adjust the position of the elastic body, the position of the elastic body needs to be determined again for each remote controller, which brings inconvenience to copying the configuration. For example: if the model airplane students replace a remote controller with the same model, the flexible limiting device 1 on the existing remote controller cannot be directly copied on a new remote controller and can only be rearranged according to the position.

In order to solve the above problems, the present invention further provides a flexible limiting device 1, where the flexible limiting device 1 includes a split 4 and an elastomer, the split 4 includes an insertion block and a positioning block 6, and the positioning block 6 is used to connect two insertion blocks, and define a position between the insertion blocks. The elastic body is fixed on the plug block, one side close to the rocker is provided with a plug pin, the plug block and the remote controller shell are provided with plug holes 10, and the plug block and the remote controller shell comprise matched plug structures for fixing, for example, the plug block is provided with the plug pin. The grafting piece pass through the grafting structure with remote controller casing fixed connection, so that the elastomer with the proportion passageway of rocker operation sets up relatively, sets up single or a plurality of elastomer along rocker operation passageway unilateral or two sides promptly, and the rocker passes through when the elastomer, the elastomer is extruded in the running direction, and the elastomer takes place elastic deformation under the exogenic action, and the resistance that the elastomer warp is overcome to the rocker passes through, and the elastomer resumes the original state. Therefore, the rocker has a stagnant feel when passing through the elastic body on each plug-in block, and has a piecewise stop touch when passing through a plurality of elastic bodies. The positioning blocks 6 between the plug-in blocks define the positions between the elastic bodies, so that the reference and the replicability are realized among the remote controllers of the same model.

The positioning block 6 in the above example can only define the positions between the elastic bodies, and cannot be simply interchanged even in the remote controllers of the same type, and the corresponding positions need to be found on the remote controllers as references to be arranged.

The invention thus provides a flexible limiting device 1, as shown in fig. 5, wherein the flexible limiting device 1 comprises a splicing element 4 and an elastic body, the splicing element 4 comprises a splicing block and a positioning connecting rod 7, the elastic body is fixed on the splicing block, the splicing block and the remote controller shell comprise a matched splicing structure for fixing, for example, a splicing needle is arranged on the splicing block, and a splicing hole 10 is arranged on the corresponding remote controller shell. The grafting piece pass through the grafting structure with remote controller casing fixed connection, so that the elastomer with the proportion passageway of rocker operation sets up relatively, sets up single or a plurality of elastomer along rocker operation passageway unilateral or two sides promptly, and the rocker passes through when the elastomer, the elastomer is extruded in the running direction, and the elastomer takes place elastic deformation under the exogenic action, and the resistance that the elastomer warp is overcome to the rocker passes through, and the elastomer resumes the original state. The rocker is thus able to feel a stagnant feel as it passes over the elastomer of each of the tiles 4 and a piecewise dwell as it passes over the plurality of elastomers. In order to enable the flexible limiting device 1 to be easily interchanged for remote controllers of the same model, a positioning reference is arranged on the remote controller, one end of the positioning connecting rod 7 is connected with the positioning reference, the other end of the positioning connecting rod is connected with the plug-in block, and the positioning connecting rod 7 limits the position of the plug-in block relative to the positioning reference on the remote controller. The positioning standard can be a cylinder which is higher than the surface of the shell of the remote controller, and a threaded hole is formed in the side face of the cylinder. Threaded holes are also formed in the side faces of the plug blocks. The positioning connecting rod 7 consists of two telescopic rods and an L-shaped connector, and the two telescopic rods can be made into a nested type, namely each telescopic rod consists of a fixed rod, a primary telescopic rod and a secondary telescopic rod. The first-stage telescopic rod is nested in the fixed rod, and the second-stage telescopic rod is nested in the first-stage telescopic rod. The primary telescopic rod is arranged as a pipe fitting, and threads are arranged inside and outside the pipe fitting. The fixing rod is provided with an internal thread which is matched with the external thread of the primary telescopic rod; the second-level telescopic rod is provided with external threads which are matched with the internal threads of the first-level telescopic rod.

Placing the model airplane on the ground, poking a left rocker on a remote controller forwards, opening an accelerator of the airplane, pulling the rocker backwards by a right hand to enable an elevator surface to tilt, taking off the model airplane, poking a right hand rocker left and right at the same time, and adjusting left and right ailerons to enable the model airplane to be gradually stable; the left hand rocker is toggled left and right to control the horizontal steering of the aircraft, the left hand rocker is pulled backwards, the accelerator is reduced, the right hand rocker is pushed forwards, the elevator surface is downward, the model airplane descends, in the whole operation process, when the rocker runs through the elastomer, the elastomer is extruded and deformed in the running direction by the rocker, the rocker slides and is stagnant when overcoming resistance, and after the rocker passes through the elastomer, the elastomer is restored to the original state. In this process, the operator knows the controlled travel to the next stage through hand perception.

And on the basis of controlling the model airplane to descend, simultaneously performing throttle reduction and elevator downward inclination operation on the remote controller rocker, and at the moment, starting a landing signal switch on the circuit board instantaneously, namely sending an electromagnet 15 power-off control signal.

Under the wireless signal instruction sent by the remote controller, the electromagnet 15 is powered off, the magnetic attraction force disappears, the protective cover 13 is ejected from the aircraft shell under the pushing of the spring 16 force of the spring 16, and is kept below the aircraft head, and becomes a protective main body when the aeromodelling lands.
