Problems solved by technology

[0004] The structure of the human-machine exoskeleton system is cumbersome and the control is complicated. It is especially difficult to recognize the human body's movement intention
Patent CN201180061461.4 discloses a control method based on a tilt sensor, which is not reliable, and the normal movement of the human body is likely to cause false triggering
Patent CN201310384919.0 discloses a method for judging human movement intention by relying on plantar pressure sensing changes. This method is only applicable to normal walking conditions of human body and cannot cover all states of human movement; patent CN200980161144.2 discloses a A method of controlling the movement of a power-assisted device by detecting changes in the plantar sensor, which also has the problem of not being able to cover all states of human body movement
In the existing technology research, such as Harbin Institute of Technology's 2011 master thesis "Exoskeleton Lower Limb Assisted Robot Technology Research" also has a method of controlling the power-assisted device by measuring the angle between the human body's large and small legs. The problem with this method is that it lags seriously. , it is difficult to achieve the ideal effect of sports assistance

Embodiment 1

[0067] Such as figure 1 , figure 2 , Figure 9 with Figure 10 As shown, a portable sports assisting device includes a power system, a control system and an actuator. The power system includes a motor, a reducer, a clutch, a transmission shaft, a transmission sprocket, a transmission chain, a motor drive circuit and a power supply. The control system It includes a processor, a memory and a signal receiving circuit. The actuator includes a connecting rod structure that cooperates with the lower limbs of the human body to bear weight, and a sensor group. The sensor group includes a human body pressure monitoring system 291 for monitoring the pressure on the human foot, and a monitoring connection The mechanical pressure monitoring system 292 of the pressure on the rod structure, the human body pressure monitoring system 291 and the mechanical pressure monitoring system 292 respectively output signals to the control system, and the control system outputs control signals to the...

Embodiment 2

[0089] The control principle of this embodiment 2 and the structure of the motion assisting device are similar to those of embodiment 1, the difference is that the foot structure 211 adopts such as image 3 As shown in the structure, the foot structure 211 of this embodiment 2 includes a mechanical base 2111 and a human foot pad 2112, the lower part of the mechanical base 2111 extends forward and sideways, and a human foot pad is installed on the upper surface of the extension of the mechanical base 2111 2112, the lower part of the mechanical base 2111 is installed with a mechanical pressure sensor 2113 for monitoring the pressure of the connecting rod structure, and the mechanical pressure sensor 2113 covers the lower surface of the mechanical base 2111. The upper part of the mechanical base 2111 and the lower part of the human foot pad 2112 are installed with a human body plantar pressure sensor 2114 for monitoring the pressure on the human body foot. The human body plantar p...

Embodiment 3

[0091] The control principle of this embodiment 3 and the structure of the motion assisting device are similar to that of embodiment 2, the difference is that the foot structure 211 adopts such as Image 6 , Figure 7 structure shown. The bottom layer of the foot structure 211 contains a hard elastic thin plate 2115, on which a mechanical pressure sensor 2113 is fixed, on which the mechanical base 2111 is fixed, and the mechanical base 2111 can bear the connecting rod structure The pressure of the human body plantar pressure sensor 2114 is fixed on the mechanical base 2111, with a human body foot pad 2112 thereon. Adding an elastic thin plate 2115 at the bottom of the foot mechanism can enable the foot structure 211 to accurately measure human foot pressure and mechanical pressure in more complex terrains; the elastic thin plate can be an elastic manganese steel sheet or an elastic fiber sheet.

Abstract

The invention relates to a light motion assisting device and a control method thereof. The light motion assisting device includes a power system, a control system and an execution mechanism; the execution mechanism includes a connection rod structure and a sensor group, which match and bear a lower limb of a human body; the sensor group includes a human body pressure monitoring system for monitoring the pressure acted on a foot of the human body, and a mechanical pressure monitoring system for monitoring the pressure acted on the connection rod structure, wherein the human body pressure monitoring system and the mechanical pressure monitoring system output signals to the control system respectively; the control system outputs a control signal to the power system; and the power system drives the connection rod structure to match the human body to move, and then a loop control system is formed. The actual load of the human body and the device assisting load can be measured timely, the changing trend of the pressured acted on the human body can be monitored timely, and the motion assisting device is controlled to do a control action; and all the states of motion of the human body can be included, and the motion assisting device can timely and rapidly make a response and cannot be triggered wrongly.

Description

technical field [0001] The invention relates to a booster device, in particular to a simple and portable sports booster device and a control method for the device. Background technique [0002] People often go up stairs, climb mountains, ride bicycles and other sports in life, and these movements will make the knee joint bear a lot of force, which is easy to cause fatigue and damage the knee joint for a long time. For the elderly or people who walk with weight People are even more so. At present, wearable auxiliary mechanical devices have appeared, which can assist the elderly and the infirm to walk short distances and solve problems encountered in daily life; with the arrival of an aging society, this type of auxiliary machinery will have a wide range of applications Space, under the condition of effective cost control, this kind of commodity will even become a necessity in every family, and its popularity is very high. The applicable crowd is not limited to middle-aged a...
