Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example 1

A conventional paraglider and backpack thereof as shown in fig. 1 to 3, the paraglider includes a paraglider body 1 and a backpack 2 connected by a parachute line 3, the backpack 2 includes a backpack frame, a motor mounted on the backpack frame and connected to a propeller, and a propeller. The backpack frame is a basic structure of the whole backpack 2, and plays a role in fixing various main components, connecting the umbrella ropes 3 and enabling a flight person to carry or ride. The engine is the component that provides power. The propeller is driven by the engine to rotate, thereby generating forward thrust.

The installation of the control rope automatic control device of the paraglider on the paraglider is shown in fig. 4-6, the paraglider is powered by the embodiment, and the automatic control device is installed on the backpack 2 and connected with the control rope to automatically control the control rope to be tightened or loosened. In this embodiment, there are two automatic control devices, which are denoted as an automatic control device 41 and an automatic control device 42, and each automatic control device is connected to a control rope, that is, the automatic control device 41 is connected to the control rope 31, and the automatic control device 42 is connected to the control rope 32.

The automatic control device can realize three control modes, including: an active drive mode, a servo-assisted mode, and a manual mode.

The active driving mode, namely the automatic control device, does not need to manually pull the control rope, and the control rope is completely and autonomously driven.

The servo assistance mode is that the automatic control device can assist corresponding assistance according to the size, direction and speed of pulling force only when detecting that the control rope is pulled manually, so that labor is saved during manual operation.

The manual mode, i.e. without the need for automatic control means or in the case of a malfunction thereof, still relies on manual manipulation of the control cord in a conventional manner. At this moment, the control driving unit does not give any driving force to the winch, only rotates along with the up-and-down pulling of the control rope with the lowest resistance, and does not influence manual operation of the control rope.

As shown in fig. 8-10, each robot includes a control drive box 46 and a winch 43, the control drive box 46 is mounted on the backpack 2 and connected to the winch 43 by a drive shaft 45, and a control cord is wound on the winch 43.

The capstan 43 is provided with an annular groove for winding the control cord, and a control cord fixing point 44 is provided in the groove, to which the control cord is fixedly connected. The control cord fixing point 44 is provided at a point in the middle of the annular groove so that the control cord is fixed at the midpoint of the length of the cord wound on the capstan 43. The free length of the control rope at the two ends which are respectively released or tightened up when the winch rotates forwards and reversely is consistent, so that the effective folding and unfolding length of the control rope can be maximized as far as possible, and the practicability and convenience of paraglider control are improved. In this embodiment, the capstan 43 is provided on its outer surface with a fixed point position mark 47 corresponding to the position of the control rope fixed point 44, so that the rotation state can be easily confirmed.

The function of the winch 43 is to drive the control line up and down, as shown in fig. 11-12, and there are other ways to do this. In this example, a driving lever capable of swinging up and down around a rotating shaft at one end was used as a comparative example, and the results of comparison were shown in table 1. In the drive lever mode, as shown in fig. 14, the control cord is fixed to the other end away from the rotation shaft 51 by the control cord fixing point 53, and the control cord is pulled up and down when the drive lever 52 swings up and down. However, the mechanisms in the modes have large volume and low driving efficiency, the motion track of the control rope is not straight, and the force change is large.

TABLE 1 comparative analysis

As shown in fig. 13, the control drive box 46 includes a control circuit 463, a drive motor 461, and a transmission gear 462 connected in this order, the transmission gear 462 being connected to the drive shaft 45. In this embodiment, the control circuit 463, the driving motor 461, the transmission gear 462 and the transmission gear 462 are all existing hardware, and the control circuit 463 may be connected to the control handle or be in communication connection with the remote control station in a wireless manner. The control circuit 463 can receive the signal from the control handle, determine the required direction and speed of rotation of the winch 43 according to its internal control software, or according to an external remote control signal, and then generate an electrical signal to drive the motor to rotate according to the required direction and speed, the drive motor 461 being connected to the drive shaft 45 of the winch 43 through the transmission gear 462.

Preferably, a sensor 464 is connected to the driving shaft 45 for detecting the rotation direction, rotation speed, rotation angle and torque data of the driving shaft, and the data of the sensor is fed back to the control circuit, so as to obtain precise control of the closed loop. When the driving device breaks down and data returned by the sensor has a large deviation with expectation, the control circuit can judge that the driving device breaks down, and can give an alarm in time to prevent the potential safety hazard from deteriorating. The capstan drive shaft thus finally rotates in the desired direction and speed, which in turn drives the external capstan to rotate, and thus the control rope.
