Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of walking assistance and energy recovery, and in particular relates to a self-powered assistance device for reducing the energy consumed by human walking. Background Art
[0002] As human society progresses, various life scenarios related to social activities are becoming increasingly diverse and complex. Such changes in social life sometimes place higher demands on the human body's performance. For ordinary people, walking for long periods of time in life or work sometimes consumes a lot of energy.
[0003] Researchers analyzing human electromyographic signals have discovered that during exercise, some muscles dissipate energy as additional work (negative work). This energy is often difficult to collect and utilize, and is dissipated into the external environment. If this form of energy can be collected, stored, and effectively utilized, it would have significant practical applications.
[0004] In order to reduce the energy dissipation of human movement, researchers have proposed a variety of power-assisting devices. Traditional walking-assisting devices are mostly divided into two types: active and passive. Active devices mainly use motors and other devices to provide mechanical power to the lower limbs. If a large driving force is desired, the driving device will be designed to be very bulky, causing inconvenience to people walking. Unpowered devices store energy through the human body's natural movement and can achieve auxiliary effects without the need for additional driving force. Although they can avoid the weight brought by the driving device, they also face challenges such as insufficient driving force and inability to better adapt to the characteristics of human gait.
[0005] In response to the above problems, this patent specifically designs a self-powered power-assisting device that reduces the energy required for human walking. When worn on the human body, it collects the negative work of knee joint movement to achieve self-powered power assistance, reducing muscle activity and metabolic consumption when taking steps, thereby achieving the purpose of reducing the energy required for human walking.

[0060] The present invention has been disclosed as above with reference to preferred embodiments, but this is not intended to limit the present invention. Any technician familiar with the present invention can make slight changes or modifications to equivalent embodiments using the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention.

[0061] How it works
[0062] When in use, the self-powered power assist device is first placed on a person's back. For example, when the right leg begins walking, as the right calf is lifted, the right flexible rope 746 decreases in length. Since the right rope drive pulley 736 and the right first spring steel pulley 739 are both fixed to the right support shaft 734, they rotate simultaneously, causing the preloaded right spring steel belt 737 to rotate counterclockwise. At this point, the right second spring steel pulley 735 also rotates, causing the right drive motor 731 to rotate counterclockwise (note that the drive motor's rotation is driven counterclockwise by the preload of the spring steel belt). At this point, the control module 4 receives a signal from the encoder of the right drive motor 731 and immediately controls the energy storage module to output electrical energy to the right drive motor 731, increasing the output torque and minimizing leg muscle exertion, thereby reducing leg energy consumption. The drive motor then remains locked, providing continuous resistance to maintain a relaxed calf as the thigh swings. When the thigh swings forward, the human body requires the calf to be lowered to maintain balance. At this point, the control module 4 cuts off the power supply to the right drive motor 731, causing the motor to immediately become disabled. The calf's own weight can easily overcome the elastic damping force of the right spring steel belt 737. At this point, the right flexible rope 746 stretches and extends, driving the right driving gear to rotate clockwise. Simultaneously, the right spring steel belt 737 stores energy, and the right driving gear 738 engages with the small gear in the right sliding gear 724. When the right sliding gear 724 rotates clockwise, it rotates counterclockwise, generating a force that climbs upward along the guide slot 701-12. Subsequently, the large gear in the right sliding gear 724 engages with the generator gear 718, driving the generator motor to rotate clockwise. The generator motor generates electrical energy, which is stored in the energy storage module 3 via the control module 4, providing energy for the operation of the drive motor. Because the number of teeth can be controlled, the transmission ratio can be designed to be large, ensuring that the single-time power generation fully meets the single-time power consumption of the drive motor, forming a self-powered power-assisting solution.
[0063] Take, for example, the human body's behavioral awareness of the left leg starting to walk. When the left calf is raised, the length of the left flexible rope 703 decreases as the calf is lifted. Since the left rope drive pulley 712 and the left first spring steel pulley 714 are both fixed to the left support shaft 726, they rotate simultaneously, causing the preloaded left spring steel belt 715 to rotate counterclockwise. At this point, the left second spring steel pulley 717 also rotates, causing the left drive motor 722 to rotate counterclockwise (note that the drive motor's rotation is driven counterclockwise by the preload of the spring steel belt). At this point, the control module 4 receives a signal from the encoder of the left drive motor 722 and immediately controls the energy storage module to output electrical energy to the left drive motor 722, increasing the output torque and minimizing leg muscle exertion, thereby reducing leg energy consumption. The drive motor then remains locked, providing resistance as the thigh swings, keeping the calf relaxed. When the thigh swings forward, the human body requires the calf to lower to maintain balance. At this point, control module 4 cuts off power to the left drive motor 722, instantly disabling the motor. The calf's own weight easily overcomes the elastic damping force of the left spring steel belt 715. At this point, the left flexible rope 703 stretches, driving the left driving gear clockwise. Simultaneously, the left spring steel belt 715 accumulates energy, causing the left driving gear 713 to mesh with the small gear in the left sliding gear 727. When the left sliding gear 727 rotates clockwise, it rotates counterclockwise, generating a force that propels the left sliding gear 727 upward along the guide slot 701-10. Subsequently, the large gear in the left sliding gear 727 meshes with the generator gear 718, driving the generator motor clockwise. This generates electricity, which is stored in the energy storage module 3 via control module 4, providing energy for the drive motor. Because the number of teeth can be controlled, the transmission ratio can be designed to be large, ensuring that the power generated per single shot fully meets the power consumption of the drive motor, creating a self-powered power-assisting solution.
