Description

Technical Field

[0001] The utility model relates to a parachute training sliding vehicle adopting a magnetic powder clutch. Background Art

[0002] The parachute training system mainly includes a track and a training sliding vehicle. When in use, a parachute jumper wears a harness at the bottom of the training sliding vehicle, and the training sliding vehicle carries the training personnel to move along the track. During the movement, various simulated actions of the training sliding vehicle are used to simulate the parachute landing process for the user to conduct parachute landing training. At present, the parachute training systems on the market mainly include two types: miniaturized training equipment and large-scale training equipment. Among them, the track of the large-scale training equipment is very long, and the moving distance of the training sliding vehicle is also very long. At the same time, for such large-scale training equipment, its track often has turns or forms a circular runway type. When moving on this type of track, the training sliding vehicle needs to turn. In order to achieve different rotational speeds of the inner and outer wheels during turning, the existing training sliding vehicles mostly use two sets of motors to drive the inner and outer wheels respectively to form a differential. However, such a design scheme not only makes the structure of the training vehicle complex, with many components and high costs, but also makes the weight of the sliding vehicle too large and occupies too much space for other components or functional modules. Therefore, the utility model provides a structure of a parachute training sliding vehicle adopting a magnetic powder clutch to solve the above technical problems. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model proposes a parachute training sliding vehicle with a simple structure and differential control.

[0004] A parachute training sliding vehicle adopting a magnetic powder clutch includes a vehicle body, moving wheels, a sliding driving assembly, and a harness simulation assembly. Among them,

[0005] There are four moving wheels, which are respectively arranged at the front and rear four corners of the vehicle body to form a set of front wheels and a set of rear wheels, and can drive the entire parachute training sliding vehicle to move back and forth on the track.

[0006] The sliding driving assembly drives the two rear wheels or the front wheels to rotate simultaneously to form two driving wheels. The sliding driving assembly includes a sliding driving motor, a right-angle commutator, and a magnetic powder clutch. The sliding driving motor is installed on the vehicle body and is located between the two driving wheels. The right-angle commutator includes an input end and two output ends, and the input end is driven by the sliding driving motor, while the two output ends are respectively connected to drive the two driving wheels to rotate through a magnetic powder clutch. When turning, through the two magnetic powder clutches, the two driving wheels can quickly pass through the curve in a preset differential state.

[0007] The harness simulation assembly is arranged in the middle of the vehicle body, and is provided with a harness seat and its harness lowered to the bottom of the vehicle body, which can be worn by the trainee, so that the trainee can be carried by the parachute training scooter to walk along the track and perform parachute simulation training.

[0008] The parachute training glider provided by the utility model has two driving wheels that share one gliding drive motor, thereby being able to reduce the number of drive motors, simplify the mechanism, and reduce the equipment cost, and also reduce the excessive occupation of the installation space on the top of the vehicle body, which is beneficial to the design and installation of other functional module components. In addition, the two driving wheels are respectively connected and driven to rotate by two magnetic powder clutches. The magnetic powder clutch has the advantages of fast response speed, simple structure, low pollution, low noise, low impact vibration, and energy saving. Not only can the two driving wheels of the parachute training glider pass in a differential state when turning, thereby improving the driving stability and safety, but also the overall comprehensive performance of the parachute training gliding can be improved.

[0009] Preferably, a clearance opening is provided in the middle of the vehicle body, and a rotating seat which is rotatably installed and covers the clearance opening is provided on the top of the vehicle body, and the rotating seat is driven to rotate by a rotating motor. The harness simulation component is installed on the rotating seat, so that the harness simulation component can have a rotating motion, which can simulate more parachute scenes and provide more realistic parachute simulation training.

[0010] Preferably, the harness simulation assembly includes a harness seat controller and a harness control motor. The harness controller is mounted on the vehicle body, and is provided with four sets of reel drums and reel belts, the bottom end of the reel belts is hung on the four corners of the harness seat, and the top end is wound around the reel drums. The harness control motor is mounted on the harness seat controller, and synchronously controls the rotation of the four reel drums, thereby adjusting the state of the harness seat and simulating more parachuting scenes.

[0011] Preferably, in order to prevent the wires of the harness control motor from getting tangled and broken when the rotating seat rotates, the harness simulation component further includes a collector ring, which is mounted on the vehicle body through a bracket and extends to the top of the harness simulation component and is coaxially arranged with the rotating seat. The harness control motor is powered by the collector ring, and when the rotating seat drives the harness simulation component to rotate, the wires of the harness control motor will not be twisted or broken. On the other hand, it also allows the harness simulation component to have an unlimited rotation angle without the need for reverse return action.

[0012] Preferably, the rotating seat is provided with an opening for the winding belt to pass through, and a pair of parallel, spaced and close-to-each winding belt guide rollers are installed at the lower end of the opening, which helps to stabilize the winding and releasing of the winding belt and prevent the winding belt from being misplaced and falling off on the winding reel.

[0013] Preferably, an external tooth is provided on the outer ring of the rotating seat. The rotating motor is installed on the vehicle body and drives the rotating seat to rotate through a gear and the external tooth. The structure is simple and does not increase the weight of the rotating seat.

[0014] Preferably, the moving wheels are coated with anti-slip rubber rings, which can prevent the moving wheels from slipping when moving on the track.

[0015] Preferably, a guiding member for cooperating with the track is further provided at the bottom of the vehicle body, which can prevent the parachute training trolley from derailing when moving.

[0016] Preferably, there are four guiding members, which are respectively installed at the four corners of the vehicle body and each includes a mounting seat and a set of guiding wheels. The mounting seat is installed at the bottom of the vehicle body. The two guiding wheels are rotatably installed and are spaced apart at the bottom of the mounting seat and respectively fit on both sides of the track to clamp the track.

[0017] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0018] 1. For the parachute training trolley provided by the present invention, its two driving wheels share a sliding driving motor, so that the number of driving motors can be reduced, the mechanism can be streamlined, the equipment cost can be reduced, and the excessive occupation of the installation space on the top of the vehicle body can also be reduced, which is beneficial to the design and installation of other functional module components;

[0019] 2. The present invention uses two magnetic powder clutches to respectively connect and drive the two driving wheels to rotate. By using the advantages of the magnetic powder clutch such as fast response speed, simple structure, small pollution, low noise, small impact vibration and energy saving, not only can the two driving wheels pass through in a differential state when the parachute training trolley turns, improving the driving stability and safety, but also the overall comprehensive performance of the parachute training trolley can be improved;

[0020] 3. The power supply ring is used to supply power to the harness control motor of the harness simulation assembly. When the rotating seat drives the harness simulation assembly to rotate, the wires of the harness control motor will not be twisted or broken. On the other hand, it also allows the harness simulation assembly to have an unrestricted rotation angle without the need for a reverse return action;

[0021] 4. A guiding member for cooperating with the track is further provided at the bottom of the vehicle body, which can prevent the parachute training trolley from derailing when moving and improve the safety of equipment use. Description of the Drawings

[0031] There are four moving wheels 2, which are respectively arranged at the front and rear four corners of the vehicle body 1, forming a group of front wheels and a group of rear wheels, which can drive the entire parachute training glider to move back and forth on the track. Preferably, the moving wheels 2 are coated with anti-slip rubber rings to prevent the moving wheels 2 from slipping when moving on the track. In another embodiment, the bottom of the vehicle body 1 is also provided with a guide member 22 used in conjunction with the track to prevent the parachute training glider from derailing when moving. Specifically, there are four guide members 22, which are respectively installed at the four corners of the vehicle body 1, and each includes a mounting seat and a group of guide wheels. The mounting seat is installed at the bottom of the vehicle body 1, and the two guide wheels are rotatably installed and installed at intervals at the bottom of the mounting seat, and are respectively attached to the two sides of the track, which can clamp the track to prevent derailment.

[0032] The sliding drive assembly 3 drives the two rear wheels or front wheels to rotate at the same time, forming two driving wheels 21. The sliding drive group includes a sliding drive motor 31, a right-angle commutator 32, and a magnetic powder clutch 33. The sliding drive motor 31 is installed on the vehicle body 1 and is located between the two driving wheels 21.

When turning, the two magnetic powder clutches 33 can quickly realize that the two driving wheels 21 pass through the curve in a preset differential state.

[0033] The harness simulation assembly 4 is arranged in the middle of the vehicle body 1 and is provided with a harness seat 41 and a harness 42 lowered to the bottom of the vehicle body 1, which can be worn by the trainee, so that the trainee can be carried by the parachute training scooter to walk along the track and perform parachute simulation training.

[0034] In one embodiment, a clearance opening 11 is provided in the middle of the vehicle body 1, and a rotating seat 12 is provided on the top of the vehicle body 1 and covers the clearance opening 11. The rotating seat 12 is driven to rotate by a rotating motor 13. The harness simulation assembly 4 is installed on the rotating seat 12, so that the harness simulation assembly 4 can have a rotating motion, which can simulate more parachute scenes and provide more realistic parachute simulation training.
