Description
Technical Field
[0001] This utility model relates to the field of mobile power technology, specifically to a mobile power supply for low-current devices. Background Technology
[0002] A power bank, also known as a portable charger, is a portable power supply device typically used to power smartphones, tablets, and other electronic devices. It provides a temporary power solution when no power outlet is available. Some power banks support fast charging technology, which can provide more power in a short time and reduce charging time. Some power banks have multiple USB ports, allowing multiple devices to be charged simultaneously. In addition, most power banks have protection circuits to prevent overcharging or over-discharging of devices, ensuring safe use.
[0003] Existing power banks also have certain inconveniences in some scenarios. For example, when you need to charge your phone while exercising or running, although the power bank and phone are small enough to fit in your pocket, they can still be inconvenient as they swing around during the run. When you are constantly moving around doing housework and want to watch videos or movies, it is also inconvenient to free your hands by having your phone and power bank move with you. Summary of the Invention
[0004] The purpose of this utility model is to provide a low-current portable power bank for devices, which solves the problem that existing portable power banks are inconvenient to use in certain scenarios, such as when you need to charge your phone while exercising or running outdoors, or when you want to watch videos or movies while constantly moving around doing housework, it is inconvenient to free your hands while keeping your phone and power bank moving with you.

[0020] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.
[0021] This embodiment provides a technical solution: a portable power supply for low-current devices, such as... Figure 1-3 As shown, it includes a power supply body 1 and a wearable component 2. The power supply body 1 has multiple built-in slots 3 on its top. The power supply body 1 has multiple data connectors 4 with different connection holes on its exterior, which can charge various models of devices. When not in use, the multiple data connectors 4 are respectively locked inside the multiple built-in slots 3. When needed, the corresponding data connectors 4 are pulled out of the built-in slots 3. The power supply body 1 has a charging port 5 on its exterior for charging. Two data cable plug interfaces can be provided on the exterior of the power supply body 1 to increase the number of devices that can be charged and connected. A power switch button 7 is provided on one side of the power supply body 1.
[0022] Wearing component 2 is located on the outside of the power supply body 1. Wearing component 2 is used to wear the power supply body 1 on the user's arm, freeing the user's hands and not delaying the user from using their hands to carry out other work. Wearing component 2 includes a wearing part, which includes a connecting plate 21 fixed to the outside of the power supply body 1. An installation groove 22 is opened at the bottom of the connecting plate 21. A rotating connecting body 23 is rotatably mounted inside the installation groove 22. Both sides of the rotating connecting body 23 are fixed with fixing buckles 24. A loop 25 is provided between the outside of the two fixing buckles 24. One end of the loop 25 is fastened to one of the fixing buckles 24 with Velcro. A male Velcro 26 and a female Velcro 27 are fixed to the outside of the loop 25. The other end of the loop 25 passes through the other fixing buckle 24 and is tightened on the arm. The loop 25 is tightly worn on the user's arm by using the male Velcro 26 and the female Velcro 27 to stick together.
[0023] The rotating connector 23 has four equidistantly distributed positioning slots 28 on its exterior. The mounting inner slot 22 has a connecting slot 29 inside. Two first springs 210 are fixed inside the connecting slot 29. A positioning head 211 slides inside the connecting slot 29. One end of each of the two first springs 210 is fixed to one end of the positioning head 211. When the two first springs 210 are at their original length, one end of the positioning head 211 will be inserted into one of the corresponding positioning slots 28, thereby positioning the rotating connector 23.
[0024] The connecting plate 21 has two inner cavities 212. The wearing component 2 also includes a mounting component, which is disposed inside the two inner cavities 212. The mounting component is used to fix the charging device connected to the power supply body 1. The mounting component includes sliding plates 213 that slide inside the two inner cavities 212 respectively. Multiple connecting rods 214 are fixed to the outside of each of the two sliding plates 213. A second spring 215 is sleeved on the outside of each of the multiple connecting rods 214. One end of each of the multiple connecting rods 214 extends to the outside of the connecting plate 21 and is fixed with a mounting plate 216. When the second spring 215 is at its original length, the mounting plate 216 is close to one side of the power supply body 1, and the charging device, such as a mobile phone, is placed between the two mounting plates 216 and fixed in place by the two mounting plates 216.
[0025] When in use, wrap the strap 25 around your arm and pull one end of the strap 25 through one of the fastening buckles 24. Use the male Velcro 26 and female Velcro 27 to attach the strap 25 to your arm. Unplug the data connector 4 corresponding to your phone model to charge your phone. In situations where your hands are inconvenient to use, such as when running or doing housework, after wearing the power supply body 1, push the two mounting plates 216 to increase the distance between them. When the distance between them increases, pull the sliding plate 213 through the connecting rod 214 connected to it to compress the second spring 215. Place the phone on the power supply body 1 and between the two mounting plates 216. Then release the mounting plates 216. With the second spring 215 returning to its original position, the distance between the two mounting plates 216 will decrease, fixing the phone in place. This frees up your hands without interfering with subsequent phone operation.
[0026] Rotate the power supply body 1 in a direction that allows it to rotate. At this time, the rotating connector 23 will push the positioning head 211 out of the positioning groove 28 and into the connector groove 29 along the arc of the positioning groove 28, thus squeezing the first spring 210. After rotating 90 degrees, another positioning groove 28 will correspond to the positioning head 211. Under the push of the first spring 210, the positioning head 211 will be stuck into the positioning groove 28. By analogy, the power supply body 1 can be rotated 90 degrees or 180 degrees to change the orientation of the power supply body 1 and the mobile phone on the arm.
[0027] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
