Description

Technical Field

[0001] This utility model relates to the field of aviation simulation equipment technology, and in particular to an aviation maintenance simulation training device. Background Technology

[0002] Aircraft maintenance is a core component of ensuring aviation safety. Its work is highly specialized and involves complex operational scenarios, such as repairing aircraft doors, engine compartments, and underwings at different altitudes. This demands extremely high practical skills from maintenance personnel. Aircraft maintenance simulation training devices, as crucial equipment for practical training, must accurately replicate real maintenance scenarios to help maintenance personnel familiarize themselves with operating procedures, improve emergency response capabilities, and simultaneously avoid the high costs and safety risks associated with training on actual aircraft.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following shortcomings often exist: Traditional simulation training devices often have training chairs with fixed heights or manually adjustable structures, which cannot accurately adapt to the maintenance heights of different parts of the aircraft. For example, maintenance of the fuselage underside requires a low sitting posture, while maintenance of the engine compartment requires a high sitting posture. Manual adjustment relies on manual force, resulting in low adjustment accuracy, slow speed, and difficulty in stably locking at the target height. This leads to a significant deviation between the training scenario and the real maintenance environment, preventing maintenance personnel from developing precise muscle memory and operating habits, thus affecting training effectiveness.

[0004] Low training efficiency and limited adaptability: The height adjustment of traditional devices requires a separate interruption of training for operation, and cannot be dynamically adjusted according to the training process, resulting in poor training continuity; moreover, the fixed height design can only adapt to a single maintenance scenario. Different training devices need to be replaced for different models and different maintenance parts, resulting in high equipment investment costs and large training space occupation, which seriously restricts the efficiency of batch training. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of large height deviation and poor scene adaptability due to traditional manual adjustment. To this end, we propose an aviation maintenance simulation training device.

[0006] To achieve the above objectives, this application adopts the following technical solution: an aircraft maintenance simulation training device, including a base, a servo motor fixedly connected to the surface of the base, a lead screw fixedly connected to the output end of the servo motor, a threaded plate threadedly connected to the arc surface of the lead screw, and a training chair fixedly connected to one side of the threaded plate.

[0007] Preferably, the training chair has two U-shaped frames fixedly connected to its surface, a setting block is fixedly connected to the surface of the base, a mounting plate is fixedly connected to one side of the setting block, and the mounting plate is slidably connected to the inner surface of the U-shaped frames.

[0008] Preferably, a fixed frame is fixedly connected to one side of the training chair, a rod is slidably inserted into the fixed frame, an elliptical plate is fixedly connected to one end of the rod, a magnet is fixedly connected to the other end of the rod, and an iron strip is fixedly connected to the inner surface of the fixed frame.

[0009] Preferably, the surface of the base has four fixing holes, which are elliptical in shape.

[0010] Preferably, a cushioning seat cushion is fixedly connected to the surface of the training chair.

[0011] Preferably, the surface of the cushioning seat has several anti-slip grooves.

[0012] Preferably, the dimensions of the mounting plate are adapted to the dimensions of the inner surface of the U-shaped frame.

[0013] The technical effects and advantages of this utility model are as follows: The servo motor drives the lead screw to rotate, which in turn drives the threaded plate and training chair to rise and fall smoothly in the vertical direction through the threaded transmission. The servo motor can be programmed to precisely control the speed and rotation angle, so as to achieve millimeter-level adjustment of the height of the training chair and accurately adapt to the height requirements of different maintenance parts of the aircraft. The adjustment process is highly automated and does not require manual operation. The height can be dynamically adjusted according to the training process to ensure that the training scenario is highly consistent with the real maintenance environment. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Reference Figure 1-4 As shown, this utility model provides a technical solution: an aircraft maintenance simulation training device, including a base 1, a servo motor 2 fixedly connected to the surface of the base 1, a lead screw 3 fixedly connected to the output end of the servo motor 2, a threaded plate 4 threadedly connected to the arc surface of the lead screw 3, and a training chair 5 fixedly connected to one side of the threaded plate 4. The servo motor 2 drives the lead screw 3 to rotate, and through threaded transmission, drives the threaded plate 4 and the training chair 5 to smoothly rise and fall in the vertical direction. The servo motor 2 can be precisely controlled by programming to adjust the speed and rotation angle, achieving millimeter-level adjustment of the height of the training chair 5, accurately adapting to the height requirements of different maintenance parts of the aircraft; the adjustment process is highly automated, requiring no manual operation, and the height can be dynamically adjusted according to the training process, ensuring that the training scenario is highly consistent with the real maintenance environment.

[0022] Reference Figure 2 As shown in this embodiment: two U-shaped frames 7 are fixedly connected to the surface of the training chair 5, and a mounting block 16 is fixedly connected to the surface of the base 1. A mounting plate 6 is fixedly connected to one side of the mounting block 16, and the mounting plate 6 is slidably connected to the inner surface of the U-shaped frames 7. The sliding contact between the U-shaped frames 7 and the mounting plate 6 can distribute the pressure of the weight of the training chair 5 and the personnel on the lead screw 3, avoiding thread wear and deformation caused by the lead screw 3 bearing a single axial load for a long time; at the same time, the sliding contact can distribute the concentrated force to the contact surface between the mounting plate 6 and the U-shaped frames 7, reduce local stress concentration, extend the service life of transmission components such as the lead screw 3 and the threaded plate 4, and reduce equipment maintenance costs.

[0023] Reference Figure 3 As shown in this implementation scheme: a fixed frame 8 is fixedly connected to one side of the training chair 5. A rod 9 is slidably inserted into the fixed frame 8. An oval plate 10 is fixedly connected to one end of the rod 9, and a magnet 11 is fixedly connected to the other end of the rod 9. An iron strip 12 is fixedly connected to the inner surface of the fixed frame 8. When maintenance personnel need to use maintenance tools such as wrenches and screwdrivers during training, the rod 9 can be fixed in the fixed frame 8 by attracting the iron strip 12 with the magnet 11. The oval plate 10 can be used to place or hang tools. When tools are needed, the rod 9 can be removed by pulling the oval plate 10, eliminating the need to find a place to store tools, reducing training interruption time, and improving operational continuity. At the same time, the fixing method of the magnet 11 facilitates quick access and adapts to the need for frequent tool switching during maintenance operations.

[0024] Reference Figure 1 As shown in this embodiment, the base 1 has four elliptical fixing holes 13 on its surface. During actual installation, the pre-drilled mounting holes on the training ground may have positional deviations. The elliptical fixing holes 13 provide lateral or longitudinal adjustment margins, allowing operators to fix the base 1 with expansion bolts without re-drilling, significantly reducing installation difficulty. Especially in large-scale installation scenarios such as aviation training bases, this can shorten the installation time for a single device and improve batch deployment efficiency.

[0025] Reference Figure 1 As shown in this embodiment, a cushioning seat 14 is fixedly connected to the surface of the training chair 5. During simulated maintenance training, maintenance personnel need to sit on the training chair 5 for extended periods. The cushioning seat 14 is made of highly elastic material, conforming to the curve of the human hip, distributing body pressure, and reducing fatigue in the hips and lower back caused by prolonged sitting. Simultaneously, the softness of the seat enhances sitting comfort, allowing maintenance personnel to focus on training operations, extending the duration of each training session, and improving training efficiency.

[0026] Reference Figure 1 As shown in this embodiment, the surface of the cushioning seat 14 is provided with several anti-slip grooves 15. During training, maintenance personnel may need to lean forward or turn to the side. The anti-slip grooves 15 on the surface of the cushioning seat 14 can increase the friction between the human body and the seat, preventing slippage caused by body movements. Especially in summer when sweating or when the seat surface is slightly damp, the anti-slip grooves 15 can effectively prevent slippage, ensuring that personnel can maintain a stable sitting posture in various operating positions and improving operating accuracy.

[0027] Reference Figure 4 As shown in this embodiment, the dimensions of the mounting plate 6 are matched with the dimensions of the inner surface of the U-shaped frame 7. This precise fit between the mounting plate 6 and the inner surface of the U-shaped frame 7 limits the lateral swaying of the U-shaped frame 7, ensuring that the training chair 5 always moves along the guide trajectory of the mounting plate 6 during height adjustment, avoiding jamming or deviation caused by excessive clearance. Especially when the training chair 5 is adjusted to its highest position, the precise fit further enhances structural stability, preventing the training chair 5 from wobbling during operation and ensuring training safety.

[0028] Working principle: The operator places the base 1 in the preset position on the training ground. According to the position of the preset mounting holes on the ground, the expansion bolts are passed through the four oval fixing holes 13 on the surface of the base 1. If there is a positional deviation of the preset mounting holes, the oval fixing holes 13 can provide horizontal or vertical adjustment margin, and the bolt position can be adjusted without re-drilling, which greatly reduces the installation difficulty. Especially when installing on a large scale in aviation training bases, it can shorten the installation time of a single device and improve the efficiency of batch deployment. When tightening the expansion bolts, the bolt position can be finely adjusted through the oval fixing holes 13 to calibrate the level of the base 1, ensuring that the subsequent lifting trajectory of the training chair 5 is vertical and avoiding equipment failure caused by the tilt of the base 1. At the same time, the adjustment margin of the oval fixing holes 13 can disperse the stress generated by the forced fixing of the bolts, prevent the base 1 from deforming or cracking, extend the service life of the base 1, and ensure the long-term stable operation of the device.

[0029] After installation, tools are prepared and seats are adjusted before training to ensure smooth training. Maintenance personnel place wrenches, screwdrivers, and other necessary tools on the elliptical plate 10. A rod 9 is slidably inserted into the mounting bracket 8 on one side of the training chair 5. One end of the rod 9 is fixed to the elliptical plate 10, and the other end is fixed to a magnet 11. The magnet 11 attracts the iron strip 12 on the inner surface of the mounting bracket 8, thus securing the rod 9 within the bracket 8 and fixing the elliptical plate 10 and tools. The magnet 11 facilitates quick tool access, and the rod 9 can slide and extend along the mounting bracket 8. The length is designed to accommodate the storage needs of tools of different sizes, preventing loss or damage caused by careless placement and maintaining a tidy training environment. The cushioning seat 14 fixed to the surface of the training chair 5 is made of highly elastic material, which can conform to the curve of the human buttocks. The maintenance personnel can adjust their sitting posture according to their own sitting habits. The cushioning seat 14 can distribute body pressure and reduce fatigue from prolonged sitting. At the same time, the anti-slip grooves 15 on the surface of the cushioning seat 14 can increase the friction between the human body and the seat. Even if you sweat in summer or the seat is slightly damp, it can prevent the sitting posture from slipping, ensuring a stable sitting posture during training and preparing for subsequent long-term training.

[0030] Based on the needs of the simulated maintenance scenario, the height of the training chair 5 is dynamically adjusted to ensure that the training scenario is consistent with the real environment. The servo motor 2 on the surface of the base 1 is activated, and the output end of the motor drives the lead screw 3 to rotate. Since the lead screw 3 is threadedly connected to the threaded plate 4, the threaded plate 4 will drive the training chair 5 to rise and fall vertically along the axis of the lead screw 3. The servo motor 2 can be precisely controlled by programming to control the speed and rotation angle, so as to achieve millimeter-level adjustment of the height of the training chair 5. For example, the height can be lowered when simulating the maintenance of the bottom of the aircraft fuselage, and raised when simulating the maintenance of the engine compartment, accurately adapting to the height requirements of different maintenance parts, without the need for manual operation, thus improving the adjustment efficiency.

[0031] During the raising and lowering of the training chair 5, the two U-shaped frames 7 fixed on its surface slide along the inner surface of the mounting plate 6 on one side of the block 16 on the base 1. The size of the mounting plate 6 matches the inner surface size of the U-shaped frame 7 with a very small gap, which can limit the lateral sway of the U-shaped frame 7 and ensure that the training chair 5 always rises and falls smoothly along the guide trajectory of the mounting plate 6, avoiding jamming or deviation caused by excessive fit clearance. At the same time, the sliding fit between the U-shaped frame 7 and the mounting plate 6 can distribute the pressure of the weight of the training chair 5 and the personnel on the lead screw 3, avoiding thread wear and deformation caused by the lead screw 3 bearing a single axial load for a long time, extending the service life of transmission components such as the lead screw 3 and the thread plate 4, and reducing equipment maintenance costs. Especially when the height of the training chair 5 is adjusted to the high position, the double guide structure can further enhance stability, prevent the training chair 5 from shaking during operation, and ensure training safety.

[0032] After the height is adjusted to the correct position, simulation training is conducted. After the training, tools are stored and equipment is reset. Maintenance personnel conduct simulated maintenance training on training chair 5. If tools are needed, the plug 9 and tools can be retrieved by pulling the oval plate 10 without interrupting the training to find the tools, thus improving the continuity of operation. When leaning forward or turning to the side during training, the anti-slip grooves 15 of the cushioning cushion 14 can ensure a stable sitting posture and avoid operational errors caused by slipping. The cushioning cushion 14 can also absorb slight vibrations of the training chair 5, reducing the feeling of bumps and improving the safety of the personnel. This allows maintenance personnel to focus on training operations and enhances the effectiveness of training.

[0033] Training End and Reset: After training, place the tools back on the elliptical plate 10 and use the magnet 11 to attract the return rod 9; start the servo motor 2 in reverse to lower the training chair 5 to the initial height; check if the tools are complete and the equipment is working properly to prepare for the next training session; the whole process does not require complicated disassembly operations, simplifying the training process and improving training efficiency.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
