Description

Knee-support power bank

This invention is a knee-support type of portable power source, specifically one that can actively generate and store electrical energy while the user is exercising.

Note: With the widespread use of wearable devices and personal power banks, mobile devices play an important role in outdoor activities, mountaineering and exploration, or rescue missions. However, in remote areas or where there is a lack of immediate charging facilities, mobile devices are prone to running out of power and losing their function, which in turn affects personal safety and the ability to make immediate contact.

Currently, there are technologies that combine portable power sources with human activities, such as integrating hand-cranked generators, solar panels, or piezoelectric elements into backpacks or clothing to recover energy from the user's movements or exercise. However, such devices are often bulky, inconvenient to wear, or limited by specific environmental conditions (such as sunlight) and cannot provide stable power, resulting in limited application effectiveness.

In addition, existing wearable power generation devices mostly focus on the design of a single power generation module, lacking an effective integration and storage control mechanism for the generated power, as well as the function of real-time transmission of stored power information, making it impossible to grasp the status of backup power in real time, thus reducing the practicality and reliability of the device.

In view of this, the creator has specifically researched and improved the knee brace in order to improve the above problems with a better design. After a long period of research and development and continuous testing, this creation was finally born.

Therefore, in order to achieve the above objectives, we, the creators, provide a knee brace-type mobile power supply, which includes: a knee brace having a micro-generator internally, the micro-generator being composed of a plurality of nanowires, the micro-generator generating mechanical energy through movement; an energy storage unit disposed inside or around the knee brace; and a processing unit coupled to the micro-generator and the energy storage unit; the processing unit receiving the mechanical energy and converting it into electrical energy, and storing the electrical energy in the energy storage unit.

According to the knee-padded portable power supply mentioned above, the processing unit is further coupled to a rectifier module and a voltage regulator module. The rectifier module and the voltage regulator module are used to convert the AC power output by the processing unit into DC power and stabilize its output voltage.

According to the knee-support type power supply mentioned above, the processing unit is further coupled to a charging control module, which is used to determine the charging status of the energy storage unit.

According to the aforementioned knee-padded portable power bank, the processing unit is further coupled to a wireless transmission module, which is used to transmit power information from the power storage unit to an external device.

According to the above-mentioned knee brace portable power supply, a power output interface is provided on the outer side of the knee brace. The power output interface is coupled to the power storage unit, so that a mobile device can be coupled to the power output interface and connected to the power supply.

According to the aforementioned knee-support type power bank, the knee brace is made of elastic fabric, and the micro-generator and the energy storage unit are fixed on the elastic fabric.

In the aforementioned knee-support type power bank, the energy storage unit is a flexible energy storage element that can bend according to the movement.

According to the aforementioned knee brace power bank, the micro-generator is installed in a movable area of the knee brace to improve the efficiency of mechanical energy collection.

Based on the above description and settings, it is evident that this creation mainly possesses the following advantages and functions, which are detailed below:

1. This invention can instantly recover the mechanical energy generated by knee bending during daily walking, climbing, or rescue operations, and convert it into stable electrical energy stored in a flexible energy storage unit through the processing unit. In addition, this invention can provide a stable backup power with minimal interference and high mobility, and is especially suitable for resource-scarce, high-risk, or power-free environments, further enhancing the battery life and safety of mobile communication devices in outdoor situations.

2. The processing unit of this invention integrates the rectifier module, the voltage regulator module, and the charging control module, and can work with the wireless transmission module and the power output interface to give this invention more complete power processing and information management capabilities. In addition to charging the mobile device in real time, users can also monitor the power storage status wirelessly, thereby enhancing the device's intelligence level and practicality.

This invention is a knee-support type portable power source. Its implementation methods, features and effects are explained in detail below with several preferred and feasible embodiments and illustrations, so that you can gain a deeper understanding and agree with this invention.

First, please refer to Figures 1 and 2. This creation is a knee-support type portable power bank, which includes:

A knee brace 1 has a micro-generator 11 installed inside. The micro-generator 11 is composed of a plurality of nanowires 111. The micro-generator 11 generates mechanical energy through movement. In one embodiment, the micro-generator 11 is disposed in a movable area A of the knee brace 1 to improve the efficiency of mechanical energy collection.

An energy storage unit 13 is disposed inside or around the knee brace 1; in this embodiment, the energy storage unit 13 is a flexible energy storage element that can bend according to movement; in a preferred embodiment, the knee brace 1 is made of elastic fabric, and the micro-generator 11 and the energy storage unit 13 are fixed on the elastic fabric; in one embodiment, a power output interface 12 is provided on the outer side of the knee brace 1, and the power output interface 12 is coupled to the energy storage unit 13, thereby allowing a motor 2 to be coupled to the power output interface 12 and connected to a power source; and

A processing unit 14 is coupled to the micro-generator 11 and the energy storage unit 13. The processing unit 14 receives mechanical energy, converts it into electrical energy, and stores the electrical energy in the energy storage unit 13. In one embodiment, the processing unit 14 is coupled to a rectifier module 141 and a voltage regulator module 142. The rectifier module 141 and the voltage regulator module 142 are respectively used to convert the AC power output by the processing unit 14 into DC power and stabilize it. Output voltage; and in another embodiment, the processing unit 14 is coupled to a charging control module 143, which is used to determine the energy storage state of the energy storage unit 13, thereby controlling the energy storage unit 13 to be in a charging mode or a discharging mode; in yet another embodiment, the processing unit 14 is coupled to a wireless transmission module 144, which is used to transmit power information of the energy storage unit 13 back to an external device 3.

Therefore, this invention, by placing the micro-generator 11 inside the knee brace 1 and collecting the mechanical energy generated by a user's knee movement through the nanowires 111, transmits it to the processing unit 14 to convert it into electrical energy and stores it in the energy storage unit 13. It can serve as a portable wearable power generation system that does not rely on external energy. Moreover, this invention can generate electricity in a way that is more in line with the natural activities of the human body, making it suitable for high-uncertainty situations such as mountaineering and rescue, and improving the immediacy and convenience of power supply.

Regarding the configuration of the rectifier module 141 and the voltage regulator module 142, please refer to Figures 1 and 2. They can effectively convert the electrical energy output by the processing unit 14, i.e., the unstable AC power, into more stable DC power, thereby improving the overall system power supply quality and safety. This helps to ensure stable voltage during subsequent storage and power supply, avoiding energy storage failure or damage to the mobile device 2 due to voltage fluctuations, and further improving the compatibility and service life of this invention.

Regarding the material configuration of the knee brace 1, please refer to Figures 1 and 2. The knee brace 1 is made of elastic fabric, and the micro-generator 11 and the energy storage unit 13 are fixed on it. This ensures that the micro-generator 11 conforms to the curve of the knee muscles and deforms with the user's movement, achieving high mobility and wearing stability, thereby improving the user's comfort, reducing fatigue from wearing for a long time, and reducing the risk of decreased power generation efficiency of the micro-generator 11 due to movement displacement.

Regarding the configuration of the energy storage unit 13 in this invention, please refer to Figures 1 and 2. The energy storage unit 13 adopts a flexible structure, which can deform in accordance with the bending motion of the knee without being damaged, thereby improving the durability of this invention.

Regarding the configuration of the micro-generator 11, please refer to Figures 1 and 2. The micro-generator 11 is placed in the most frequently moving movable area A of the knee brace 1, which can effectively improve the mechanical energy harvesting efficiency and power output performance. This configuration can maximize the energy conversion efficiency generated by the knee joint in walking, climbing and other actions, increase the available power, and help improve the power generation capacity and application of the overall system.
