[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0028] At present, the main body of remote-controlled toy airplanes is generally made of foam plastic material, and two propellers are arranged at the ends of the wings on both sides facing the tail for driving. Such remote-controlled toy airplanes are generally operated to take off on land or in the air. The foam plastic material can make the airplane float on the water and glide on the water. However, when gliding on the water, the fuselage, wings, propellers and other structures of the remote-controlled toy airplane will all be in contact with the water surface, that is, the bottom surface of the remote-controlled toy airplane is entirely attached to the water surface. The remote-controlled toy airplane can be driven to glide on the water surface through the propellers. However, in this way, the remote-controlled toy airplane has a large contact area with the water surface, so it cannot take off directly on the water surface and can only glide on the water surface, and its usage scenarios are limited.

[0029] Please refer to Figures 1 to 5The utility model provides a remote-controlled seaplane 100, comprising: a fuselage 10; a hull 20, wherein the hull 20 is fixedly connected to the bottom of the fuselage 10; a wing assembly 30, wherein the wing assembly 30 comprises a first wing 31 and a second wing 32, wherein the first wing 31 and the second wing 32 are respectively connected to the two sides of the fuselage 10; a tail assembly 40, wherein the tail assembly 40 is fixedly connected to the tail of the fuselage 10; a driving assembly 50, wherein the driving assembly 50 comprises a first driving member 51 and a second driving member 52, wherein the first driving member 51 and the second driving member 52 are respectively arranged on the first wing 31 and the second wing 32, wherein the first driving member 51 is located on a side of the first wing 31 away from the hull 20, and the second driving member 52 is located on a side of the second wing 32 away from the hull 20.

[0030] Specifically, the remote-controlled seaplane 100 includes a fuselage 10, a hull 20, a wing assembly 30, a tail assembly 40 and a drive assembly 50. The fuselage 10 is provided with an installation space inside for installing components such as batteries and circuit boards. The hull 20 is used to make the fuselage 10 float on the water surface so that the remote-controlled seaplane 100 can glide on the water surface and keep the fuselage 10 and the wing assembly 30 from getting wet. The remote-controlled seaplane 100 can fly directly from the water surface into the air. The wing assembly 30 is used to generate lift to support the remote-controlled seaplane 100 to fly in the air. The tail assembly 40 is used to maintain the heading balance of the aircraft to ensure that the aircraft can fly smoothly. The drive assembly 50 is used to generate pulling force and thrust to move the remote-controlled seaplane 100 forward.

[0031] The driving assembly 50 is configured as a first driving member 51 and a second driving member 52. The two driving members are fixed on two wings. The side of the wing facing away from the hull 20 refers to the top surface of the wing. The fuselage 10 floats on the water through the hull 20. By arranging the two driving members on the top surfaces of the two wings, contact with water can be avoided, reducing the contact area between the remote-controlled seaplane 100 and the water. When the remote-controlled seaplane 100 takes off from the water, the contact area is small, which can better allow the remote-controlled seaplane 100 to leave the water and fly into the air.

[0032] The driving member can be a rubber band power, a motor or a piston engine, etc. Two driving members are arranged on the two wings, with dual power. The remote-controlled seaplane 100 needs to be given a certain power to leave the water surface. When the power is below the power, the remote-controlled seaplane 100 will glide in the water. When the power is increased to exceed the power value, the remote-controlled seaplane 100 will gradually leave the water surface and fly into the air. With dual power, whether the remote-controlled seaplane 100 is gliding on the water surface or flying in the air, it can fly relatively stably. At the same time, the two driving members are arranged at intervals, which can also increase the stability of the flight.

[0033] The technical solution of the utility model is to arrange a hull 20 at the bottom of the fuselage 10, so that the remote-controlled seaplane 100 can float on the water surface and glide on the water surface through the hull 20. Floating through the hull 20 can reduce the contact area between the fuselage 10 and the wing and the water surface. When power is given, the remote-controlled seaplane 100 can glide on the water surface. When the power reaches a certain value, the remote-controlled seaplane 100 can take off from the water surface and fly in the air; at the same time, the first driving member 51 and the second driving member 52 are respectively arranged on the surfaces of the first wing 31 and the second wing 32 away from the hull 20. When the remote-controlled seaplane 100 glides in the water, the first driving member 51 and the second driving member 52 can avoid contact with water, reduce the contact area between the remote-controlled seaplane 100 and the water surface, so that the remote-controlled seaplane 100 can take off from the water surface better.

[0034] In one embodiment, a first mounting position 311 and a second mounting position 321 are respectively provided on the top surfaces of the first wing 31 and the second wing 32 , the first driving member 51 is installed at the first mounting position 311 , and the second driving member 52 is installed at the second mounting position 321 .

[0035] In detail, the installation position can be opened or protruded on the wing body, or a fixing platform can be set on the top surface of the wing to form the installation position. The installation position is set to facilitate the installation of the first driving member 51 and the second driving member 52.

[0036] In one embodiment, the wing assembly 30 further includes a first winglet 33 and a second winglet 34, wherein the first winglet 33 and the second winglet 34 are symmetrically arranged at the top of the first wing 31 and the second wing 32, respectively, and the first mounting position 311 and the second mounting position 321 are recessedly formed on the first winglet 33 and the second winglet 34, respectively.

[0037] Specifically, Figure 4 , a first winglet 33 and a second winglet 34 are provided, two mounting positions are formed on the first winglet 33 and the second winglet 34, a first driving member 51 is placed at the first mounting position 311 and fixed on the first winglet 33, and a second driving member 52 is placed at the second mounting position 321 and fixed on the second winglet 34. By providing the first winglet 33 and the second winglet 34, the two driving members can be better fixed; at the same time, the first winglet 33 and the second winglet 34 can effectively hinder the air flow around the upper and lower wing surfaces, thereby reducing the induced drag, increasing a part of the lift of the first wing 31 and the second wing 32, improving the climbing ability of the aircraft, improving the efficiency of the wings, and enhancing the stability of the aircraft.

[0038] In addition, in this embodiment, Figure 1The first wing 31 and the second wing 32 are both streamlined to reduce wind resistance. The two wings are extended along both sides of the fuselage 10 and have a certain length. The two first winglets 33 and the second winglet 34 are arranged in the middle of the wings to maintain the flight stability of the remote-controlled seaplane 100.

[0039] In one embodiment, the first driving member 51 includes a first motor 511 and a first propeller 512, the first motor 511 is installed at the first mounting position 311 of the first winglet 33, and the first propeller 512 is fixedly connected to the output end of the first motor 511; the second driving member 52 includes a second motor (not marked in the figure) and a second propeller (not marked in the figure), the second motor is installed at the second mounting position 321 of the second winglet 34, and the second propeller is fixedly connected to the output end of the second motor.

[0040] In detail, Figure 3 and Figure 5 In this embodiment, the first driving member 51 is configured to include a first motor 511 and a first propeller 512. The first motor 511 is placed in the first mounting position 311 and fixed on the first winglet 33. The center of the first propeller 512 is sleeved outside the output shaft of the first motor 511. The first propeller 512 is driven by the first motor 511 to rotate to provide power for the remote-controlled seaplane 100, which has the characteristics of light weight, low cost and durability. The first motor 511 is located on the top surface of the first wing 31, thereby preventing the first propeller 512 from hitting the water surface and hindering take-off.

[0041] Similarly, the second driving member 52 is configured as a second motor and a second propeller, and its effects refer to those of the first driving member 51 described above, and are not elaborated herein.

[0042] In one embodiment, the first motor is a coreless motor; and / or the second motor is a coreless motor.

[0043] In detail, the types of the first motor 511 and the second motor can be selected according to actual needs. In the prior art, brushless motors are mostly used, which are expensive, powerful, and dangerous.

[0044] In this embodiment, the first motor 511 and the second motor are hollow cup motors. The hollow cup motor is small in size, low in cost, and has suitable power, and is suitable for making toy airplanes. The toy remote-controlled seaplane 100 of the utility model is very suitable for playing in ponds, small lakes, amusement parks, etc.

[0045] In one embodiment, the first propeller 512 is located at an end of the first motor 511 facing away from the head of the fuselage 10, and the second propeller is located at an end of the second motor facing away from the head of the fuselage 10; or, the first propeller 512 is located at an end of the first motor 511 facing the nose of the fuselage 10, and the second propeller is located at an end of the second motor facing the head of the fuselage 10; or, the first propeller 512 is located at an end of the first motor 511 facing away from the hull 20, and the second propeller is located at an end of the second motor facing away from the hull 20.

[0046] It is worth noting that the orientation of the first propeller 512 and the second propeller can be set according to actual needs, and can be set at a position facing the nose, or at a position facing the tail, or at a position facing away from the hull 20. The specific position can be selected according to actual needs. Figure 3 In this embodiment, the first propeller 512 and the second propeller are both located facing the tail of the aircraft to facilitate providing power and thrust.

[0047] In the prior art, when the remote-controlled seaplane 100 is flying over a pond or a lake, if it accidentally slides to a corner and cannot turn forward, it is necessary to manually salvage the remote-controlled seaplane 100, which is very inconvenient to use. In this embodiment, the first motor 511 and the second motor are configured to have forward and reverse functions. This is achieved through software and controlled by remote control. When the remote-controlled seaplane 100 slides to a corner, the propeller is reversed by reversing the motor, and the remote-controlled seaplane 100 can be controlled to move backward, thereby realizing the backward movement of the aircraft. There is no need to manually pick up the remote-controlled seaplane 100 that has flown to a corner, which is very convenient to use.

[0048] In one embodiment, the first mounting position 311 is located at one end of the first winglet 33 close to the tail assembly 40, and the second mounting position 321 is located at one end of the second winglet 34 close to the tail assembly 40; the end of the first winglet 33 away from the tail assembly 40 is streamlined, and the end of the second winglet 34 away from the tail assembly 40 is streamlined.

[0049] Specifically, the positions of the first installation position 311 and the second installation position 321 can be set according to actual needs, such as Figure 4 The first mounting position 311 and the second mounting position 321 are both disposed close to the tail assembly 40, so that the first motor 511 and the second motor are disposed close to the tail assembly 40, so as to dispose the first propeller 512 and the second propeller at a position facing the tail.

[0050] like Figure 4The first mounting position 311 and the second mounting position 321 are opened along the top of one end of the first winglet 33 and the second winglet 34 to the middle, forming the first mounting position 311 and the second mounting position 321, which is convenient for installing the first motor 511 and the second motor. The first motor 511 and the second motor can be directly placed and fixed on the first mounting position 311 and the second mounting position 321, so that the first propeller 512 and the second propeller are installed at a position close to the tail assembly 40 to generate thrust and power, so that the aircraft can fly more stably. At the same time, the first winglet 33 and the second winglet 34 are set to be streamlined at one end away from the tail assembly 40, that is, the windward section of the first winglet 33 and the second winglet 34 is streamlined, which can reduce wind resistance.

[0051] In one embodiment, the first driving member 51 also includes a first fixed shell 513, the first fixed shell 513 is installed at the first mounting position 311 of the first winglet 33, the first fixed shell 513 is provided with a first mounting groove 5131, and the first motor 511 is installed in the first mounting groove 5131; the second driving member 52 also includes a second fixed shell (not marked in the figure), the second fixed shell is installed at the second mounting position 321 of the second winglet 34, the second fixed shell is provided with a second mounting groove (not marked in the figure), and the second motor is installed in the second mounting groove.

[0052] Specifically, a first fixing shell 513 and a second fixing shell are provided, and the first motor 511 and the second motor are connected to the first winglet 33 and the second winglet 34 respectively through the first fixing shell 513 and the second fixing shell, so as to facilitate the fixing of the first motor 511 and the second motor.

[0053] like Figure 3 The end surface of the first fixed shell 513 is flush with the end surface of the first winglet 33, the first motor 511 is arranged in the first installation groove 5131 along the length direction of the fuselage 10, and the output end of the first motor 511 is arranged to extend from the end surface of the first winglet 33; this design facilitates the rotation of the first propeller 512. The end surface of the second fixed shell is flush with the end surface of the second winglet 34, the second motor is arranged in the second installation groove along the length direction of the fuselage 10, and the output end of the second motor is arranged to extend from the end surface of the second winglet 34; this design facilitates the rotation of the second propeller.

[0054] The first mounting position 311 of the first winglet 33 has a first positioning step 331 protruding from the bottom wall, and the first fixing shell 513 has a first positioning groove 5132 recessed from the bottom wall, and the first positioning groove 5132 is matched with the first positioning step 331; the mounting position of the second winglet 34 has a second positioning step (not shown in the figure) protruding from the bottom wall, and the second fixing shell has a second positioning groove (not shown in the figure), and the second positioning groove is matched with the second positioning step. This design facilitates the positioning and installation of the first fixing shell 513 and the second fixing shell on the first winglet 33 and the second winglet 34, making the fixing of the motor and the propeller more stable and the flight more stable.

[0055] In one embodiment, a stern of the hull 20 is provided with an avoidance groove 21 , and the bottom wall of the avoidance groove 21 is streamlined.

[0056] It is worth noting that by providing the avoidance groove 21, when the remote-controlled seaplane 100 needs to take off from the water surface, the power is increased, the nose of the fuselage 10 is pulled up, and the tail of the hull 20 can reduce the contact with the water surface through the avoidance groove 21, so that the aircraft can take off from the water surface better. The bottom wall of the avoidance groove 21 is also streamlined to reduce wind resistance, so that the hull 20 can glide smoothly on the water surface even when it contacts the water surface.

[0057] In one embodiment, the tail assembly 40 includes a vertical tail 41 and a horizontal tail 42, the vertical tail 41 is fixedly connected to the top surface of the tail of the fuselage 10, the middle part of the horizontal tail 42 is fixedly connected to the top of the vertical tail 41, the horizontal tail 42 is extended along both sides of the fuselage 10, and the horizontal tail 42 and the wing assembly 30 are staggered in the height direction.

[0058] In detail, the vertical tail 41 and the horizontal tail 42 are fixed in angle, and cooperate with the wings. Under the power of the two propellers, the nose of the remote-controlled seaplane 100 is pulled up and gradually rises from the water surface. Figure 2 and Figure 3 The vertical tail 41 is arranged vertically along the top surface of the fuselage, and the horizontal tail 42 is fixedly connected to the top of the vertical tail 41. This design can prevent the tail assembly 40 from contacting the water surface, avoid affecting the remote-controlled seaplane 100 from taking off from the water surface, and facilitate the remote-controlled seaplane 100 to leave the water surface and take off from the water. At the same time, the horizontal tail 42 and the wing assembly 30 are staggered in the horizontal direction, which can balance the fuselage 10.

[0059] The utility model further provides an aircraft system (not shown in the figure), comprising a remote controller (not shown in the figure) and the remote-controlled seaplane 100 as described above, wherein the remote controller is in communication connection with the remote-controlled seaplane 100 .
