Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to a toy airplane and a connecting bracket. Background Technology

[0002] Toy airplanes capable of flight or gliding are a popular category among children and aviation enthusiasts. By mimicking the shapes and movements of real aircraft, they provide users with an immersive play experience. These toy airplanes typically use lightweight materials for their fuselages and achieve flight or gliding through internal power units or external forces. They come in various styles, including fixed-wing and rotary-wing, satisfying children's curiosity and imagination about flight while also offering adults the enjoyment of collecting and operating them.

[0003] In the structural design of toy airplanes, the main wheels are key components supporting the fuselage and enabling ground taxiing. Their installation method directly affects the toy's performance and durability. Currently, most toy airplanes fix their main wheels to the fuselage via axles. However, due to overall size limitations, the main wheels and axles are often relatively small. This design results in insufficient overall strength at the main wheel mounting point, making it prone to breakage and loosening during frequent landings, collisions, or when bearing the weight of the fuselage. Some products use steel wire as the supporting connector for the main wheels to improve structural strength. However, steel wire is prone to deformation under stress. During the gliding takeoff and / or landing phases, the impact force on the steel wire causes the angle between the wire and the fuselage to widen from 90 degrees to an obtuse angle, causing the wheel to deviate. This leads to the toy airplane veering or tilting during taxiing, severely affecting taxiing stability and user experience. Utility Model Content

[0004] The main purpose of this invention is to propose a toy airplane that aims to solve the problem of unstable connection between the main wheels and the fuselage.

[0005] To achieve the above objectives, the toy airplane includes:

[0006] The fuselage is equipped with at least one drive motor;

[0007] Connecting brackets, each of the connecting brackets connecting to one of the machine bodies, the drive motor being located within the connecting bracket; and

[0008] The main wheel is rotatably located at the end of the connecting bracket away from the drive motor.

[0009] In one embodiment of the present invention, the connecting bracket has a fixed cavity, the drive motor is limited in the fixed cavity, and the drive motor is interference-fitted or transition-fitted with the fixed cavity.

[0010] In one embodiment of this utility model, the connecting bracket and the housing of the drive motor are an integral structure.

[0011] In one embodiment of this utility model, the connecting bracket has a fixed end, the fixed end includes a first fixed section and two second fixed sections, the two second fixed sections are symmetrically located at one end of the first fixed section, and the body is provided with a first limiting groove and two second limiting grooves, the two second limiting grooves are symmetrically located at one end of the first limiting groove;

[0012] The first fixed segment limiter is matched with the first limiting groove, and each second fixed segment limiter is matched with a second limiting groove;

[0013] The drive motor is located within the first fixed section.

[0014] In one embodiment of the present invention, the first fixing segment is in the shape of a hollow cylinder, and each of the second fixing segments is in the shape of a flat plate.

[0015] In one embodiment of the present invention, one of the second fixed segment and the second limiting groove is provided with a plug-in segment, and the other of the second fixed segment and the second limiting groove is provided with a plug-in groove, and each plug-in segment is plugged into one plug-in groove.

[0016] In one embodiment of this utility model, a wire passage groove is provided between the two second limiting grooves, and the wire passage groove is connected to the first limiting groove.

[0017] In one embodiment of the present invention, the connecting bracket has a connecting portion, the connecting portion including a first connecting segment and a second connecting segment, the first connecting segment being disposed at the end of the first fixing segment near the second fixing segment and located between the two second fixing segments; the second connecting segment extending in a direction away from the body, and the main wheel being disposed at the end of the second connecting segment away from the body;

[0018] The first connecting section covers part of the structure of the wire groove and the first limiting groove.

[0019] In one embodiment of the present invention, the end of the second connecting segment away from the body forms two spaced and aligned connecting arms, the two connecting arms forming a rotation space, and the main wheel is located in the rotation space and rotatably connected to the connecting arms.

[0020] This utility model also proposes a connecting bracket, which includes a fixed end and a connecting part. The fixed end includes a first fixed segment and two second fixed segments, with the two second fixed segments symmetrically located at one end of the first fixed segment.

[0036] The main purpose of this utility model is to propose a toy airplane 100, which aims to solve the problem of unstable connection between the main wheel 30 and the fuselage 10.

[0037] To achieve the above objectives, please refer to Figure 1 The toy airplane 100 includes a fuselage 10, a connecting bracket 20, and a main wheel 30. The fuselage 10 is equipped with at least one drive motor. Each connecting bracket 20 is connected to a fuselage 10, and the drive motor is located in the connecting bracket 20. The main wheel 30 is rotatably located at the end of the connecting bracket 20 away from the drive motor.

[0038] In this technical solution, the main wheel 30 is instead rotatably mounted on the far end of the extended connecting bracket 20. The bracket provides an independent and enlarged mounting surface for the wheel body, allowing the wheel diameter to be appropriately increased without increasing the size of the fuselage 10. This directly improves the contact stability and anti-rollover capability with the ground by using a larger wheel body cross-section and a wider hub support surface. The landing impact and taxiing load on the main wheel 30 are first dispersed by the bracket and then transmitted to the fuselage 10. This avoids the problems of insufficient strength, bending deformation and axis misalignment caused by the size limitation of traditional shafts or steel wires, and significantly improves the connection stability, taxiing straightness and service life of the toy airplane 100 main wheel 30 and fuselage 10.

[0039] In this utility model, toy airplane 100 refers to an airplane type with flight or gliding capabilities. This type of airplane has a control system, circuit system, drive motor, etc. Taking a remote control airplane as an example, the remote control airplane is equipped with a communication module to connect with the remote controller. The user issues commands such as forward, backward, and acceleration through the remote controller. The remote control airplane receives these command information and implements these commands through the control system and circuit system to achieve the user's corresponding purpose.

[0040] The fuselage 10 integrates a control system, circuit system and other structures. A connecting bracket 20 is installed at its tail. The drive motor is fixed inside the connecting bracket 20. The connecting bracket 20 is fixed to the fuselage 10 by means of plugging, snapping, screwing and other methods. At the same time, the connecting bracket 20 and the fuselage 10 are reinforced with adhesive to prevent them from loosening.

[0041] The fuselage 10 and main wheel 30 are fixed to both ends of the connecting bracket 20, respectively. The main wheel 30 is rotatably connected to the connecting bracket 20 through a rotating shaft structure. The output shaft of the drive motor drives the propeller to rotate and generate thrust. The main wheel 30 is a driven gliding wheel, connected to the fuselage 10 through the bracket and subjected to thrust to achieve ground gliding and gliding. The bracket provides a larger mounting surface for the wheel, allowing for an increase in wheel diameter without increasing the fuselage 10, thus improving ground contact stability and anti-rollover capability. At the same time, the landing impact and gliding load of the toy airplane 100 are first dispersed by the bracket and then transferred to the fuselage 10, avoiding problems such as bending caused by stress deformation of traditional small rotating shafts or steel wires. Furthermore, because the connecting bracket 20 is directly connected to the drive motor... Together, the main wheel is connected to the connecting bracket 20. Thus, the body 10 no longer needs to set up a separate fixed area for the installation position of the connecting bracket 20 and the main wheel 30. For the body 10, integrating the housing of the drive motor, the connecting bracket 20 and the main wheel 30 into one position can reduce the design difficulty and processing steps of the body 10 when it is manufactured. At the same time, it can optimize the spatial layout of the body 10, making more fixed area for fixing other functional modules. Meanwhile, by using the installation area that cannot be reduced for installing the drive motor, the housing of the drive motor and the main wheel 30 are connected through the connecting bracket 20. In this way, the main wheel 30 does not need to occupy the space of the body, thereby reducing the space of the main wheel 30 on the body.

[0042] In one embodiment, the connecting bracket 20 has a fixed cavity 20a, in which the drive motor is confined. The drive motor and the fixed cavity 20a are either interference-fitted or transition-fitted. Specifically, the connecting bracket 20 is designed as a structure with an internal cavity (fixed cavity 20a). The size and shape of this cavity precisely match the housing of the drive motor. The two are securely "locked" in the fixed cavity 20a by using either an interference fit (the motor is slightly larger than the cavity, requiring a certain amount of pressure to install, resulting in a more secure connection) or a transition fit (the motor and cavity are close in size, making installation easy and the fit tight). This method ensures that the drive motor will not wobble or shift within the connecting bracket 20, providing a more reliable installation and helping to ensure the stability of the motor output and the overall rigidity of the connecting bracket 20, thereby indirectly improving the stability of the main wheel 30 connection.

[0043] In another embodiment, the connecting bracket 20 and the housing of the drive motor are an integral structure. Specifically, the connecting bracket 20 and the housing of the drive motor can be fused into a single component using an integral molding process such as injection molding or die casting, completely eliminating the connection gap and assembly error between the two. This structure allows the power output of the drive motor and the load of the fuselage 10 to be directly transmitted through the integral structure, eliminating the performance degradation problem caused by wear or loosening of the connecting parts 22 in traditional split designs. At the same time, the integral structure reduces the number of parts, simplifies the production process, reduces assembly costs, and significantly improves overall rigidity, enabling better resistance to landing impacts and fatigue stress during long-term use.

[0044] In one embodiment, the connecting bracket 20 has a fixed end 21, which includes a first fixed segment 211 and two second fixed segments 212. The two second fixed segments 212 are symmetrically located at one end of the first fixed segment 211. The body 10 is provided with a first limiting groove 10a and two second limiting grooves 10b, which are symmetrically located at one end of the first limiting groove 10a. The first fixed segment 211 is fitted with the first limiting groove 10a, and each second fixed segment 212 is fitted with one second limiting groove 10b. The drive motor is located within the first fixed segment 211. Please refer to [link / reference]. Figure 2 and Figure 3 The fixed end 21 of the connecting bracket 20 is designed in a "Y" shape, with one first fixed segment 211 connecting two symmetrical second fixed segments 212. The body 10 is correspondingly provided with matching "Y"-shaped limiting grooves (one first limiting groove 10a connects two symmetrical second limiting grooves 10b). By inserting the three branches of the connecting bracket 20 into the corresponding three grooves of the body 10, limiting fit is achieved. The fit between the two symmetrically distributed second fixed segments 212 and the second limiting grooves 10b forms auxiliary support. The symmetrical structure offsets lateral forces, preventing the connecting bracket 20 from tilting or shifting when subjected to uneven forces. This design transforms the concentrated force of a traditional single connection point into a multi-point distributed force, significantly reducing local stress. Combined with the layout of the drive motor built into the first fixed segment 211, the overall center of gravity is closer to the connection center, further improving structural stability.

[0045] Specifically, the first fixing segment 211 is in the shape of a hollow cylinder, and each of the second fixing segments 212 is in the shape of a flat plate. Please refer to [link / reference]. Figure 3 The first fixing section 211 is designed as a hollow cylinder. This shape facilitates the accommodation of a cylindrical drive motor and may also reduce the weight of the connecting bracket 20. The second fixing section 212 is designed as a flat plate. This shape provides a larger contact area when it mates with the limiting groove of the body 10, which helps to disperse the stress at the connection and improve the stability of the connection. It also facilitates the design of possible clips, screw holes, or adhesive surfaces on the flat plate.

[0046] In one embodiment of this utility model, one of each second fixing segment 212 and each second limiting groove 10b is provided with a plug-in segment 213, and the other of each second fixing segment 212 and each second limiting groove 10b is provided with a plug-in groove 10c. Each plug-in segment 213 is plugged into a plug-in groove 10c. Specifically, each second fixing segment 212 has a protruding plug-in segment 213 at its outer edge, and each second limiting groove 10b has a plug-in groove 10c at its bottom. When the connecting bracket 20 is inserted into the body 10, the plug-in segment 213 will be inserted into the plug-in groove 10c, forming a "locking" effect. This plug-in structure provides additional longitudinal fixing force to prevent the connecting bracket 20 from shifting due to vibration or impact during use, further enhancing the stability of the connection; in another embodiment, each second fixing segment 212 has a recessed plug-in groove 10c at its outer edge, and each second limiting groove 10b has a raised plug-in segment 213 at its bottom. Since the two technical solutions bring the same beneficial effects, they will not be explained again here.

[0047] Please see Figure 2 A wire-passing groove 10d is provided between the two second limiting grooves 10b, and the wire-passing groove 10d connects to the first limiting groove 10a. Specifically, the wire-passing groove 10d is located between the two second limiting grooves 10b and is connected to the first limiting groove 10a. This provides a convenient and neat channel for the drive motor's wires, allowing them to pass through the gap between the connecting bracket 20 and the body 10 from the motor (located inside the first fixed section 211) to the inside of the body 10. This avoids the wires being squeezed or worn, ensures the reliability of the electrical connection, and also makes the overall structure neater.

[0048] Please see Figure 2 and Figure 3In one embodiment of this utility model, the connecting bracket 20 has a connecting portion 22, which includes a first connecting segment 221 and a second connecting segment 222. The first connecting segment 221 is located at the end of the first fixed segment 211 near the second fixed segment 212 and between the two second fixed segments 212. The second connecting segment 222 extends in a direction away from the body 10, and the main wheel 30 is located at the end of the second connecting segment 222 away from the body 10. The first connecting segment 221 covers part of the structure of the wire groove 10d and the first limiting groove 10a. The segmented design of the connecting portion 22 achieves a smooth transition between the fixed end 21 and the main wheel 30. The first connecting segment 221 is located between the two second fixed segments 212 and acts as a kind of "reinforcing rib". It not only enhances the overall rigidity of the fixed end 21, but also provides secondary protection for the internal wires by covering part of the structure of the wire groove 10d and the first limiting groove 10a, preventing dust and debris from entering or the wires from accidentally coming out. The second connecting section 222 extends in the direction away from the fuselage 10, so that the main wheel 30 maintains an appropriate distance from the fuselage 10 and avoids friction caused by the bottom of the fuselage 10 contacting the ground during taxiing; at the same time, the extended design provides space for adjusting the spacing of the main wheels 30, which makes it easier to further improve taxiing stability by optimizing the wheel track.

[0049] Furthermore, at the end of the second connecting segment 222 furthest from the fuselage 10, two spaced and aligned connecting arms are formed. The two connecting arms form a rotation space 222a. The main wheel 30 is located in the rotation space 222a and rotates to connect the connecting arms. Please refer to [link to relevant documentation]. Figure 3 The two sides of the main wheel 30 are connected by a pivot through the connecting arm. The rotation space 222a formed by the two symmetrical connecting arms provides stable rotational support for the drive wheel. The spacing between them is adapted to the width of the main wheel 30, which ensures that the main wheel 30 can rotate flexibly, and restricts the axial movement of the main wheel 30 through the connecting arms on both sides, so as to avoid wheel body deviation during gliding and improve gliding smoothness. At the same time, the rigid structure of the connecting arm can effectively withstand the lateral force transmitted by the main wheel 30 and prevent the main wheel 30 from tilting.

[0050] Please see Figure 2 and Figure 3This utility model also proposes a connecting bracket 20, which includes a fixed end 21 and a connecting part 22. The fixed end 21 includes a first fixed segment 211 and two second fixed segments 212, which are symmetrically located at one end of the first fixed segment 211. The connecting part 22 includes a first connecting segment 221 and a second connecting segment 222. The first connecting segment 221 is located at the end of the first fixed segment 211 near the second fixed segment 212 and between the two second fixed segments 212. The second connecting segment 222 extends in a direction away from the fuselage 10 of the toy airplane 100. The end of segment 222 away from the fuselage 10 forms two spaced and aligned connecting arms, which together form a rotation space 222a. The first fixed segment 211 is configured to accommodate the drive motor of the toy airplane 100, and the rotation space 222a is configured to accommodate the main wheel 30 of the toy airplane 100. For the specific structure of the connecting bracket 20, please refer to all the above embodiments. The connecting bracket 20 proposed in this technical solution can adopt all the technical solutions of the connecting bracket 20 in the above embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here.
