Description

Technical Field

[0001] This utility model relates to the technical field of parachute training equipment, specifically to an ergonomic manned support for a parachute training simulator. Background Technology

[0002] In parachute training for paratroopers, skydivers, and other similar groups, skydiving simulators are crucial ground training equipment, playing an irreplaceable and key role in improving trainees' skill levels. Skydiving training is a high-risk and technically demanding activity. Ground training using simulators allows trainees to repeatedly practice skydiving techniques in a safe and controlled environment, familiarizing themselves with various situations during the jump, thereby effectively reducing the risks of actual jumps and improving training efficiency and success rates.

[0003] Skydiving training simulators accurately simulate the attitudes and G-forces during each stage of a skydive, including freefall, parachute deployment, control, and landing, creating a near-realistic skydiving environment for trainees. The manned frame, as the core component of the simulator, bears the crucial responsibility of directly supporting the trainee and executing various complex movement commands. Its performance directly affects whether trainees can obtain accurate motion feedback during simulated training, and has a profound impact on training effectiveness and trainee safety.

[0004] However, the manned support structures used in most parachute training simulators currently on the market have significant shortcomings. These manned supports are mostly suspended or have limited design features, resulting in considerable functional limitations. Due to these structural design flaws, such manned supports are not sensitive or precise in controlling the trainee's posture and cannot fully simulate the leg position during a parachute jump, i.e., the relative angle between the legs and torso (including freefall, gliding, and diving). This makes it difficult for trainees to maintain a standard and accurate posture during simulated training, and they cannot obtain an experience and feedback highly consistent with real parachute jumps.

[0005] For example, in a parachute simulator disclosed in CN215932896U, although the simulator simulates some aspects of the parachute environment by setting up a parachute platform and air supply device, providing trainees with a certain degree of realism, its design of the manned support structure still fails to adequately address the critical issue of the relative angle between the legs and torso. When trainees use this simulator for training, the effectiveness of the simulation training is significantly reduced, failing to truly meet the trainees' needs for mastering and improving their parachute skills, thus affecting the overall quality and efficiency of the parachute training work. Utility Model Content

[0006] In view of this, the present invention provides an ergonomic manned support for a parachute training simulator. The present invention can control the posture of the trainee more quickly and accurately, and adjust the position and angle of the legs during parachute training, thereby improving the safety and stability during actual parachute operation.

[0007] To solve the above-mentioned technical problems, this utility model provides an ergonomic manned support for a parachute training simulator, including a back plate set on the support, the back plate being used to fix the torso, and a support plate at the end of the back plate. The support plate and the back plate are arranged in an L-shape. After the operator's torso is fixed on the back plate, the legs can be close to the front of the support plate, that is, the angle between the front of the back plate and the front of the support plate is greater than 180°. The support plate is provided with a leg fixing mechanism, which is used to fix the operator's legs. The relative position between the leg fixing mechanism and the back plate can be adjusted, thereby adjusting the relative angle between the legs and the torso.

[0008] The leg restraint mechanism includes two straps that are connected to the support plate, each strap being secured to the user's ankle.

[0009] The support plate has two through holes, and the binding strap can move within the through holes. The back of the support plate is also equipped with a roller frame, on which take-up and release rollers are mounted. The take-up and release rollers can rotate on the roller frame and the binding strap is wound on the take-up and release rollers. A motor is also mounted on the back plate corresponding to the two take-up and release rollers. The motor can indirectly drive the two take-up and release rollers to rotate. The rotation of the take-up and release rollers can adjust the position of the end of the binding strap.

[0010] The corresponding motor is also equipped with a speed reducer. The output shaft of the motor is connected to the speed reducer, and the two output shafts of the speed reducer are respectively connected to the two take-up and release frame shafts. The speed reducer is used to increase the torque of the motor.

[0011] Two guide frames are also provided on the back of the support plate. Each guide frame is fixed at the perforation for guiding the restraint strap.

[0012] The back panel has a hinged frame at one end, and the other end of the frame is snapped to the back panel. A sandwich space is formed between the frame and the back panel, which is used to place the umbrella bag. The umbrella bag straps can pass through the frame and are located on the front of the frame.

[0013] The support frame is also equipped with multiple sensor modules, which are used to detect whether the operator's movements are standard.

[0014] An emergency stop button is also provided on the back of the support plate or back plate.

[0015] The support frame can be rotated to allow operators to train in freefall, gliding, and other similar scenarios.

[0016] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0017] 1. Enhance the realism of the movement:

[0018] This support frame, with its L-shaped backplate and support plate structure, and adjustable leg anchoring mechanism, can accurately and quickly simulate the trainee's posture during skydiving, as well as the relative angle changes between the legs and torso (such as freefall, gliding, and the transition between the two). Compared to traditional suspended or simple support frames, trainees can perform complex movements such as rotation, pitch, roll, and tilt, with movements more closely resembling actual skydiving scenarios, thus significantly improving training effectiveness.

[0019] 2. Optimize human-machine efficiency:

[0020] The ergonomic design allows trainees to maintain a natural and comfortable posture during extended simulated training sessions. The leg support mechanism dynamically adjusts leg position through the coordinated action of straps, retractable rollers, and a motor: during freefall, the leg straps tighten to align the thighs with the body, distributing pressure on the lower back; after parachute deployment, the straps loosen to allow for movement during landing. This design effectively alleviates lower back fatigue and avoids the discomfort caused by concentrated stress in traditional support systems.

[0021] 3. Enhance security:

[0022] Multiple safety protection mechanisms ensure that risks are controllable throughout the training process. On the one hand, the articulated frame and buckle connection design securely place the parachute in the back panel, preventing displacement during rapid posture changes. On the other hand, the emergency stop button and mechanical self-locking function (worm gear reducer and brake motor) provide double protection, ensuring that even if the equipment loses power or malfunctions, trainees can maintain a fixed posture and avoid collision injuries.

[0023] 4. Precise motion feedback:

[0024] The integrated sensor module on the support frame can monitor the trainee's movements in real time (such as the force of the pull ring and the angle of posture), providing instructors with quantitative data support. This function not only helps trainees correct technical deviations in a timely manner, but also provides objective evidence for evaluating training effectiveness, thereby promoting the improvement of training quality.

[0025] 5. Adaptable to multi-scenario training:

[0026] The frame supports 360° rotation, simulating complex flight trajectories such as freefall, gliding, and turning, meeting comprehensive training needs from basic movements to advanced tactics. Its modular design (such as detachable restraint straps and a movable frame) also facilitates quick adjustments for trainees of different body types, enhancing the equipment's versatility.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0033] This embodiment provides an ergonomic manned support 1 for a parachute training simulator, such as... Figure 1 , 3 As shown: The support includes a support frame 1 for supporting the operator. The support frame 1 includes a rectangular plate-shaped back plate 2. The operator's torso can be fixed to the front of the back plate 2, and a support plate 3 is fixed to the end of the back plate 2. The support plate 3 and the back plate 2 are arranged in an L-shape. After the operator's torso is fixed to the back plate 2, the legs can be close to the front of the support plate 3, that is, the angle between the front of the back plate 2 and the front of the support plate 3 is greater than 180°. The support plate 3 is provided with a leg fixing mechanism for fixing the operator's legs. The leg fixing mechanism includes two restraint straps 4 connected to the support plate 3. The end of each restraint strap 4 can be fixed to the ankle. The relative distance between the end of the restraint strap 4 and the support plate 3 can be adjusted, thereby indirectly adjusting the position of the operator's legs, and thus achieving the purpose of adjusting the relative angle between the legs and the torso.

[0034] Specifically, the leg fixing mechanism includes a through hole 5 provided in the support plate 3, such as... Figure 1 , 3As shown: A motor 7 is fixedly installed on the back of the support plate 3 corresponding to the perforation 5. The motor 7 is a drive motor. Two roller frames are also fixedly installed on the back of the support plate 3 corresponding to the drive motor. Each roller frame has a take-up and release roller 6 that is rotatably mounted on it. The take-up and release roller 6 is used to wrap the restraint strap 4. The restraint strap 4 passes through the perforation 5 and is fixed on the operator's ankle. The output shaft of the drive motor can drive the two take-up and release rollers 6 to rotate simultaneously through the transmission connection. This allows the relative distance between the end of the restraint strap 4 and the support plate 3 to be adjusted, thereby enabling the operator's leg to be adjusted.

[0035] Preferably, the support plate 3 is also provided with two guide frames 9 on its back. Each guide frame 9 is fixed at the perforation 5. The binding strap 4 on the take-up and take-down roller 6 passes through the guide and then through the perforation 5, thereby avoiding hard friction between the binding strap 4 and the inner wall of the perforation 5.

[0036] Preferably, the take-up and release roller 6 has an I-shaped cross-section, which can prevent the binding strap 4 from falling off the take-up and release roller 6 during the take-up and release process.

[0037] Preferably, the back of the support plate 3 is also provided with a reducer 8, which has one input end and two output ends. That is, the reducer 8 is a worm gear reducer 8. The output shaft of the drive motor is connected to the input end of the reducer 8, and the two output ends of the reducer 8 are respectively connected to the rotating shafts of the two take-up and release rollers 6. Thus, the reducer 8 can not only make the two take-up and release rollers 6 rotate synchronously, but also enhance the torque of the drive motor, and make the rotation of the two take-up and release rollers 6 more stable.

[0038] Furthermore, the front of the back panel 2 is provided with a movable frame 10, such as... Figure 1 , 2 As shown: A sandwich space is formed between the movable frame 10 and the front of the back panel 2. The sandwich space is used to place the umbrella bag 11, and the carrying strap of the umbrella bag 11 can be connected to the movable frame 10. The movable frame 10 is located on the front of the movable frame 10, which securely places the umbrella bag 11 in the sandwich space of the back panel 2 to prevent the umbrella bag 11 from shifting when the posture changes rapidly.

[0039] Correspondingly, one end of the movable frame 10 is connected to the back panel 2 via a hinge, and the other end of the movable frame 10 is connected to the back panel 2 via a snap-fit ​​connection, which makes it easy to remove the umbrella bag 11 from the interlayer space for replacement or maintenance.

[0040] It is worth mentioning that the support 1 can drive the back plate 2 and the connecting plate to rotate as a whole, which enables the operator to perform complex flight trajectories such as diving, gliding, and landing, meeting the all-round training needs from basic movements to advanced tactics.

[0041] Correspondingly, the bracket 1 is also equipped with multiple sensor modules 13, which can be used to detect whether the operator's use is standard for later scoring; at the same time, the support plate 3 is also equipped with an emergency stop button 12 on the back side, which can temporarily stop the operation of the equipment in special circumstances to ensure the safety of the operator or other operations. The emergency stop button 12 can also be set on the side of the back plate 2, that is, at about waist level.

[0042] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
