Description

Technical Field

[0001] This utility model relates to the field of model aircraft technology, and in particular to an electric mechanism for the canopy of a space shuttle model. Background Technology

[0002] The current hatch opening and closing mechanisms of space shuttle models generally adopt a single-axis hinge and motor direct drive design, which can only achieve simple rotational opening and closing and cannot reproduce the multi-stage complex motion trajectory of a real hatch. Such structures are prone to jamming and shaking due to insufficient transmission rigidity, and lack dynamic simulation functions for end buffer and sealing structures. When closing, they often scratch the model surface. At the same time, the control lacks staged speed adjustment and position feedback, resulting in stiff movements and significant noise, which seriously restricts high-precision dynamic demonstrations and user experience.

[0003] Traditional hatch doors mostly use manual opening and closing methods, which are inconvenient and inefficient. This design innovatively improves upon this by incorporating an electric opening and closing structure. This structure mainly consists of a motor, a worm gear, a worm shaft, and hinges installed in five slots on the hatch door. During operation, the motor starts and drives the worm shaft to rotate. The worm gear meshes with the worm shaft, transmitting power to the worm wheel. The worm wheel then drives the hatch door to rotate around its axis via the hinges, achieving smooth electric opening and closing. Compared to traditional technology, this patent introduces a motor-driven worm gear transmission system, eliminating manual operation and making hatch door opening and closing more convenient, efficient, stable, and reliable. This greatly improves the user experience and the level of equipment intelligence. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electric mechanism for the hatch of a space shuttle model, which aims to improve the problem that traditional hatch doors in the prior art mostly adopt manual opening and closing methods, which are inconvenient to operate and inefficient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electric mechanism for a space shuttle model canopy, comprising a base plate, L-shaped plates fixedly connected to the front and rear sides of the top of the base plate, an arc-shaped shell fixedly connected between adjacent tops of two L-shaped plates, a bracket fixedly connected to the middle of the inner side of each arc-shaped shell, a motor fixedly connected between adjacent brackets, a worm gear fixedly connected to the output end of the motor, a worm wheel meshing with the outer wall of the worm gear, a canopy door fixedly connected to the left and right ends of the outer wall of the worm wheel, a hinge rotatably connected to the bottom end of the outer wall of the canopy door, and the other end of the hinge fixedly connected to the front and rear sides of the outer wall of the arc-shaped shell.

[0006] As a further description of the above technical solution:

[0007] The bottom front and rear sides of the arc-shaped shell are fixedly connected to a bottom shell, and the left and right sides of the arc-shaped shell are fixedly connected to a baffle.

[0008] As a further description of the above technical solution:

[0009] A long plate is fixedly connected to the top center of the base plate.

[0010] As a further description of the above technical solution:

[0011] The outer walls of the long plates are all fixedly connected with support strips at equal intervals.

[0012] As a further description of the above technical solution:

[0013] The top of the L-shaped plate is fixedly connected to support blocks at equal intervals near the edge.

[0014] As a further description of the above technical solution:

[0015] The bottom of the base plate is provided with anti-slip grooves.

[0016] As a further description of the above technical solution:

[0017] The top front side of the arc-shaped shell is fixedly connected with an annular tube.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, after the motor is started, the output power drives the worm to rotate. The worm wheel meshes with the worm, transmitting the rotational motion of the worm to the worm wheel. Subsequently, the rotation of the worm wheel is transmitted to the hinge of the hatch door through a mechanical connection. At this time, the hinge acts as a connecting component, realizing the smooth opening and closing of the hatch door. With the precise power output of the motor and the efficient transmission of the worm wheel and worm gear transmission system, the hatch door is ensured to operate stably and respond quickly during electric opening and closing, effectively solving the drawbacks of the traditional manual opening and closing method.

[0020] 2. In this utility model, the electric automation of hatch door opening and closing is achieved by using a motor-driven worm gear transmission system and hinge structure. Compared with the traditional manual opening and closing method, it greatly improves the convenience, efficiency and reliability of hatch door operation, provides a better opening and closing solution for relevant application scenarios, and can reduce the cost of manual operation, enhance the overall intelligence level of the equipment and the user experience.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides: an electric mechanism for a space shuttle model canopy, including a base plate 12, with L-shaped plates 11 fixedly connected to the front and rear sides of the top of the base plate 12, and an arc-shaped shell 8 fixedly connected between the adjacent tops of the two L-shaped plates 11, with a bracket 5 fixedly connected to the middle of the inner side of the arc-shaped shell 8, and a motor 2 fixedly connected between the adjacent sides of the two brackets 5, with a worm gear 4 fixedly connected to the output end of the motor 2, and a worm wheel 3 meshing with the outer wall of the worm gear 4, with a canopy door 7 fixedly connected to the left and right ends of the outer wall of the worm wheel 3, and a hinge 6 rotatably connected to the bottom end of the outer wall of the canopy door 7, with the other end of the hinge 6 fixedly connected to the front and rear sides of the outer wall of the arc-shaped shell 8;

[0031] Specifically, two robust and precisely sized supports 5 are located at the inner center of the arc-shaped shell 8. Between the two adjacent supports 5, a motor 2 is securely fixed, serving as the power source and possessing efficient and stable performance. The output end of the motor 2 is fixedly connected to a worm gear 4. The worm gear 4 has a smooth surface and can rotate smoothly under the drive of the motor 2. The outer wall of the worm gear 4 is tightly meshed with the worm wheel 3, ensuring precise and stable transmission. The left and right ends of the outer wall of the worm wheel 3 are fixedly connected to hatch doors 7. The size of the hatch doors 7 matches the hatch opening. The bottom of the outer wall of the hatch doors 7 is connected to a hinge 6 via a pivot. The hinge 6 is flexible and has a strong load-bearing capacity. The other end of the hinge 6 is fixedly connected to the front and rear sides of the outer wall of the arc-shaped shell 8. When the motor 2 starts, it drives the worm gear 4 to rotate, which in turn drives the worm wheel 3 to rotate. With the assistance of the hinge 6, the hatch doors 7 can achieve smooth opening and closing.

[0032] Please see the appendix Figure 4 - Appendix Figure 6 A long plate 13 is fixedly connected to the top center of the base plate 12. A base shell 1 is fixedly connected to the front and rear sides of the bottom of the arc shell 8. A baffle 9 is fixedly connected to the left and right sides of the arc shell 8. Support strips 14 are fixedly connected at equal intervals to the outer wall of the long plate 13. Support blocks 10 are fixedly connected at equal intervals to the top of the L-shaped plate 11 near the edge. Anti-slip grooves 16 are provided at the bottom of the base plate 12. A ring tube 15 is fixedly connected to the top front side of the arc shell 8.

[0033] Specifically, the baffle 9 can effectively prevent external objects from accidentally colliding with the inside of the arc-shaped shell 8. The outer wall of the long plate 13 is uniformly and evenly fixedly connected with multiple support bars 14 at equal intervals. These support bars 14 are regularly shaped and further enhance the load-bearing capacity and structural stability of the long plate 13. The L-shaped plate 11, as an important support in the device, is fixedly connected with multiple support blocks 10 at equal intervals, which can provide a stable support point for the components that cooperate with it. It is provided with anti-slip grooves 16. The texture of the anti-slip grooves 16 is clear and greatly increases the friction between the base plate 12 and the placement surface.

[0034] Working principle: The electric opening and closing structure of the hatch door 7 mainly consists of a motor 2, a worm gear 3, a worm 4, a hinge 6, and the hatch door 7 itself. After the motor 2 is started, the output power drives the worm 4 to rotate. The worm gear 3 meshes with the worm 4, transmitting the rotational motion of the worm 4 to the worm gear 3. Subsequently, the rotation of the worm gear 3 is transmitted to the hinge 6 of the hatch door 7 through a mechanical connection. At this time, the hinge 6, as a connecting component, drives the hatch door 7 to rotate around the hinge 6 axis under the transmission action of the worm gear 3, realizing the smooth opening and closing action of the hatch door 7. With the precise power output of the motor 2 and the efficient transmission of the worm gear 3 and worm 4 transmission system, the hatch door 7 is ensured to operate stably and respond quickly during electric opening and closing, effectively solving the drawbacks of the traditional manual opening and closing method.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
