Description

Technical Field

[0001] This utility model relates to the field of parachute training simulator equipment, specifically to a 3-axis angle changing device for a parachute training simulator. Background Technology

[0002] In the field of parachute training simulators, existing parachute training simulation devices are mainly used to provide parachute trainees with near-realistic simulations of aerial attitude changes, in order to assist in training their balance control, attitude adjustment, and weightlessness adaptation abilities during parachuting. Traditional parachute training simulators typically have single-axis or dual-axis angle adjustment functions, such as achieving partial attitude simulation through simple pitch or tilt mechanisms. Their core function is to reproduce the two-dimensional motion state during parachuting to a certain extent, providing trainees with a basic training environment.

[0003] Existing devices, limited by their structural design, can mostly only achieve angle changes along a single axis (such as the pitch axis) or two axes (such as the pitch axis + roll axis), making it difficult to simultaneously simulate the complex rotational motion of the X, Y, and Z axes during skydiving. For example, traditional devices may use a single rotating mechanism to pitch the backplate, but they cannot achieve rotation around the center of the backplate (similar to the spin during free fall) or overall flipping. This results in trainees not being able to experience the three-dimensional attitude changes under weightlessness in the air, leading to significant differences from the motion characteristics of actual skydiving.

[0004] Some existing technologies use mechanical linkages or simple motor drives, which can only achieve fixed angle adjustments and cannot dynamically and continuously change the angle according to training needs. For example, when it is necessary to simulate the random rotation caused by airflow disturbances encountered by skydivers in the air, traditional devices have insufficient driving precision and cannot respond to and output complex angle changes in real time, which greatly reduces the realism of the simulation scenario and affects the trainees' ability to adapt to the actual skydiving environment. Utility Model Content

[0005] In view of this, the present invention provides a 3-axis angle changing device for a parachute training simulator, which can drive the back plate to rotate in three axes by using a driving component, thereby completing the parachute training simulation.

[0006] To solve the above-mentioned technical problems, this utility model provides a 3-axis angle changing device for a parachute training simulator, including a bracket that provides a mounting point for the device. A back plate is connected to one side of the bracket, and a fastening component is provided on the back plate. The training personnel are fixed to the back plate by the fastening component to achieve a rigid connection, which makes the parachute training personnel safer and more comfortable, while also speeding up the system response efficiency.

[0007] The rotating assembly is connected to the bracket, and the back plate is connected to the rotating assembly on the side of the bracket closer to the bracket. The rotating assembly includes bearing seats connected to both ends of the bracket. The bearing seats are perpendicular to the back plate. The rotating shaft is installed in the bearing seats. The two ends of the rotating shaft are fixedly provided with lugs. The end of the lug away from the bracket has a connecting plate. The back plate is rotatably mounted on the connecting plate. The driving component is located at the end of the bearing seat away from the bracket and connected to the output end of the driving component. The gear set includes a second connecting rod located on one side of the rotating shaft. The second connecting rod has a gear. The rotating shaft also has a gear. The gear on the second connecting rod meshes with the gear on the rotating shaft. The driving component drives the gear set, which can drive the rotating shaft to rotate. When the rotating shaft rotates, it drives the lugs, which drive the connecting plate to rotate, thereby changing the angle between the bracket and the back plate.

[0008] The rotating component includes a groove located at the end of the connecting plate away from the back plate. A connecting shaft is located within the groove, with one end of the connecting shaft connected to the back plate. A driving component is connected to the side of the connecting plate away from the back plate. The output end of the driving component has a second gear set, which includes a first gear located at the output end of the driving component and a second gear located on the connecting shaft. The second gear is located within the groove. When the output end of the driving component rotates, it drives the first gear to rotate, which in turn drives the second gear to rotate. The second gear then drives the connecting shaft to rotate, which in turn drives the back plate to rotate, thus realizing the rotation function of the back plate and allowing the trainee to experience the rotation generated during free fall.

[0009] The flipping assembly includes symmetrically arranged support bases, each containing a drive component. The output end of the drive component is connected to both ends of the bracket, and the drive component is a servo motor. A lifting assembly is located at the bottom of the support bases, connected to the drive component that rotates the bracket. The function of the flipping assembly is to rotate the bracket along its axis, thus achieving the flipping function of the entire device. The support bases provide the mounting position for the drive component, which connects to the bracket via its output end, providing power for the bracket's flipping.

[0010] When the flip, rotate, and swivel components are reset, the back panel can be restored to a flat state, simulating a second umbrella opening.

[0011] Example 1: The backplate can be tilted and rotated by using a combination of rotating and swivel components.

[0012] Example 2: The tilt adjustment of the back panel can be achieved by using a combination of the rotating component and the flipping component.

[0013] Example 3: By combining the use of the rotating component, the flipping component, and the swivel component, three-axis adjustment of the backplate can be achieved, allowing trainees to have a better experience.

[0014] Drive components include, but are not limited to, servo motors.

[0015] The lifting assembly can adjust the height of the support base as needed, allowing the parachute trainees to leave the ground and have enough space to move, thus better cooperating with the drive components to achieve the rotation of the support frame;

[0016] Furthermore, the process of opening an umbrella can also be simulated when the lifting component moves the support up and down.

[0017] The lugs and connecting plates are detachable. This design facilitates the installation, commissioning, and maintenance of the device. When it is necessary to inspect or replace related components, the lugs and connecting plates can be easily removed, improving the maintainability of the device.

[0018] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0019] 1. Excellent simulation effect: By combining the rotating, flipping and swivel components, the backplate can be rotated on the X, Y and Z axes, which better simulates the posture of a parachutist falling in the air. This allows trainees to experience various motion states during free fall, such as tilting, flipping and rotating, thereby improving the realism and effectiveness of parachute training simulation.

[0020] 2. Ensuring personnel safety: The fastening components installed on the back panel can firmly fix the trainees to the back panel, forming a rigid connection, ensuring the safety of the parachute trainees during the training process, and avoiding injuries caused by the movement of the device.

[0021] 3. Improved system response efficiency: The fastening components reduce the swaying of the trainee's body, enabling the system to respond more quickly and accurately to the trainee's actions or the movement of the device, thus improving the response efficiency of the parachute training simulation system.

[0022] 4. Easy to install, debug and maintain: The lugs and connecting plates are detachable, which can be easily disassembled when it is necessary to repair or replace related parts, thus improving the maintainability of the device.

[0023] 5. High adjustability: The rotating component can change the angle between the support and the backboard to achieve the tilt adjustment of the backboard; the rotating component can drive the backboard to rotate along its center part on the side of the support, allowing the trainees to experience rotation; the flipping component can drive the support to rotate along its axis to achieve the flipping of the entire device; the lifting component can adjust the height of the support base as needed, allowing the parachute trainees to leave the ground and have enough space to move, and work with the drive components to better achieve the flipping of the support.

Detailed Implementation

[0029] 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 1-4 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.

[0030] like Figure 1-4 As shown:

[0031] This embodiment provides a 3-axis angle adjustment device for a parachute training simulator, with a bracket 2 providing a stable mounting point for the entire device. A backplate 1 is rotatably connected to one side of the bracket 2, and a fastening assembly 5 consisting of straps and buckles is provided on the backplate 1. When the trainee leans against the backplate 1, the fastening assembly 5 can securely fix their torso, limbs, and other parts to the backplate 1. This rigid connection method not only ensures the safety of the parachute trainee during training but also improves the system's response efficiency by reducing body sway.

[0032] like Figure 2 , 3 As shown in Figure 4:

[0033] The rotating assembly 100 is vertically connected to the support 2. Specifically, a bearing seat 101 is installed at each end of the support 2, with a rotating shaft 104 embedded inside each bearing seat 101. Lugs 102 are welded to both ends of the rotating shaft 104. A connecting plate 103 is bolted to the end of each lug 102 away from the support 2, and a back plate 1 is hinged to the connecting plate 103 via a pin, forming a rotatable connection structure. A drive component 3 (such as a servo motor) is installed at the end of the bearing seat 101 away from the support 2, and the output end of the drive component 3 is connected to a gear set. The gear set includes a second connecting rod located on one side of the rotating shaft 104, with gears fixedly mounted on the second connecting rod. A gear is also coaxially fixed to the rotating shaft 104, and the two sets of gears mesh with each other. When the drive unit 3 is running, it drives the gear set to rotate, which in turn causes the rotating shaft 104 to rotate in the bearing seat 101. The rotation of the rotating shaft 104 causes the support ear 102 to swing. The support ear 102 drives the back plate 1 to rotate through the connecting plate 103, thus achieving precise adjustment of the angle between the bracket 2 and the back plate 1.

[0034] like Figure 3 , 4 As shown:

[0035] A groove 301 is formed at the end of the connecting plate 103 away from the back plate 1. A connecting shaft 302 is disposed in the groove 301, and one end of the connecting shaft 302 is fixed to the back plate 1 by a key. A drive component 3 is installed on the side of the connecting plate 103 away from the back plate 1. The output end of the drive component 3 is connected to a second gear set. The second gear set includes a first gear fixed on the output shaft of the drive component 3 and a second gear mounted on the connecting shaft 302 and located in the groove 301. The first gear and the second gear mesh with each other. When the output end of the drive component 3 rotates, it drives the first gear to rotate. The first gear drives the second gear to rotate through meshing transmission. The second gear then drives the connecting shaft 302 to rotate in the groove 301. The connecting shaft 302 ultimately drives the back plate 1 to rotate around its own axis, allowing the trainee to experience the rotational motion generated during free fall.

[0036] like Figure 1 , 2 As shown:

[0037] The flipping assembly 200 consists of two symmetrically arranged support bases 201, each of which houses a servo motor as a drive component 3. The output end of the drive component 3 is fixedly connected to both ends of the bracket 2 via a coupling. A lifting assembly 4 is installed at the bottom of the support base 201, and the lifting assembly 4 is bolted to the base of the drive component 3. When the drive component 3 operates, its output torque drives the bracket 2 to rotate along its axis, thereby realizing the flipping function of the entire device. The support base 201 provides a stable mounting position for the drive component 3, while the lifting assembly 4 can adjust the height of the support base 201 according to training needs, allowing the parachute trainee to leave the ground and providing sufficient space for movement to better cooperate with the drive component 3 in completing the flipping operation of the bracket 2.

[0038] like Figure 2 , 4 As shown:

[0039] The lug 102 and the connecting plate 103 are connected by bolts in a detachable structure. Specifically, a bolt hole is provided at the connecting end of the lug 102, and a corresponding through hole is provided in the connecting plate 103. The two are then fastened together using bolts and nuts. This design offers significant advantages during the installation, commissioning, and maintenance of the device: the position of components can be flexibly adjusted during installation; the internal transmission structure is easily inspected during commissioning; and when the lug 102, connecting plate 103, or related components need to be repaired or replaced, they can be quickly separated simply by removing the bolts, greatly improving the maintainability of the device and the efficiency of component replacement.

[0040] Working principle: Trainees are secured by fastening components 5 on the backplate 1. The drive component 3 drives each component to rotate along three axes to simulate parachute training. In the rotating component 100, the drive component 3 drives the rotating shaft 104 to rotate via a gear set. The rotating shaft 104 rotates the backplate 1 through the lug 102 and connecting plate 103, changing the angle between the backplate 1 and the support 2. In the rotating component 300, the drive component 3 drives the connecting shaft 302 to rotate via a second gear set. The connecting shaft 302 drives the backplate 1 to rotate around its own axis, allowing the trainee to experience freefall rotation. In the flipping component 200, the drive component 3 within the support base 201 drives the support 2 to flip along its axis. The bottom lifting component 4 adjusts the height of the support base 201, allowing the trainee to leave the ground and cooperate in completing the flip. Through the individual or combined action of the rotating, rotating, and flipping components 200, rotation along the X, Y, and Z axes is achieved, simulating the weightlessness of parachuting.

[0041] 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.

[0042] 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.
