Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging device technology, and in particular to a portable and multifunctional charging device. Background Technology
[0002] With the widespread use of electronic devices, power banks have become an essential accessory for people when traveling, but their carrying methods still present many inconveniences. For example, without a bag, power banks usually need to be held in hand or put in a pocket. However, many garments lack pocket designs, or power banks in pockets tend to swing around, affecting movement. Holding a power bank in hand restricts the freedom of the hands and reduces the user experience. To address this, a portable, multi-functional charging device that can be magnetically attached to clothing for secure fastening could be designed. Utility Model Content
[0003] In order to overcome the shortcomings of the above-mentioned situation, this utility model aims to provide a technical solution that can solve the above problems.
[0004] A portable multi-functional charging device includes a power bank body. A rubber base is fixedly installed on the lower surface of the power bank body. The rubber base is in a circular shape. A filling layer is provided in the middle of the rubber base. A notch is cut in the filling layer and communicates with the outside of the lower surface. A removable magnetic component is provided in the notch and can be magnetically attracted to the notch.
[0005] Furthermore, the height dimension of the magnetic chuck is longer than the height dimension of the notch.
[0006] Furthermore, when the magnetic component is attached to the notch, the horizontal plane of the lower end face of the rubber base is not higher than the horizontal line of the lower end face of the magnetic component.
[0007] Furthermore, the notches in the filler layer are more than two.
[0008] Furthermore, a first metal part is provided at the bottom of the notch to attract the magnetic part.
[0009] Furthermore, a second metal element is provided on the lower surface of the filling layer to be attracted to the magnetic element.
[0010] Furthermore, the power bank itself has a data cable at its interface, which includes a main connector for connecting to the power bank's interface and multiple auxiliary connectors for connecting to other devices with different interfaces.
[0011] The beneficial effects of this utility model are:
[0012] The power bank features a removable magnetic clip that can be placed inside clothing to hold and secure it, preventing it from shifting in pockets or even in areas without pockets, thus freeing up your hands.
[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Please see Figures 1-3 The present invention includes a power bank body 1, a rubber base 2 fixedly provided on the lower surface of the power bank body 1, the rubber base 2 is in a ring shape, a filling layer 3 is provided in the middle of the rubber base 2, the filling layer 3 has a notch 4 that communicates with the outside of the lower surface, and a removable magnetic component 5 is provided in the notch 4, the magnetic component 5 can be magnetically attracted in the notch 4.
[0021] This technology relates to a portable, multi-functional charging device, mainly comprising a power bank body 1 and a rubber base 2 on its lower surface. The purpose of the rubber base 2 is to allow the power bank body 1 to be placed on a table, where the friction between the rubber and the table surface provides stability.
[0022] Meanwhile, the main feature of this technology is that the rubber base 2 is designed in a circular shape with a filling layer 3 in the middle. The filling layer 3 has a notch 4 that communicates with the outside of the lower surface. A detachable magnetic component 5 is provided in the notch 4. The magnetic component 5 is a magnetic iron block. When wearing thin everyday clothes, the magnetic component 5 can be removed, and the power bank body 1 and the magnetic component 5 can be placed on the inside and outside of the clothes respectively, so as to fix the power bank by magnetic attraction.
[0023] Specifically, the height of the magnetic component 5 is longer than the height of the notch 4, meaning that when the magnetic component 5 is attached to the notch 4, there will be an exposed portion so that it can be removed. At the same time, the magnetic component 5 may have a lateral exposed portion, thereby further improving the portability of removal.
[0024] When the magnetic component 5 is attached to the notch 4, the horizontal plane of the lower end face of the rubber base 2 is not higher than the horizontal line of the lower end face of the magnetic component 5. That is, when the magnetic component 5 is attached to the notch 4, the magnetic component 5 is still located at the middle edge of the rubber base 2. Then, when the power bank is placed on the table, the rubber base 2 is in contact with the table.
[0025] Example 1: The bottom of the notch 4 is provided with a first metal part 6 that is attracted to the magnetic part 5. The magnetic part 5 is attracted and held by removing it from the notch 4 and then aligning it with the two sides of the clothing. At this time, the magnetic part 5 is attracted to the first metal part 6 in the notch 4 again, thereby completing the fixation of the power bank body 1.
[0026] Example 2: Based on Example 1, the notches 4 of the grooves opened on the filling layer 3 are more than two, that is, there are more than two magnetic suction pieces 5 (preferably two magnetic suction pieces 5). After one magnetic suction piece 5 is taken out, it can be attracted to another magnetic suction piece 5.
[0027] Example 3: Based on Example 1 and Example 2, a second metal part 7 is provided on the lower surface of the filling layer 3 to be attracted to the magnetic part 5. This method can directly attract the magnetic part 5 to the filling layer 3 to achieve the fixing effect.
[0028] The main purpose of Examples 2 and 3 is to reduce the possibility of wrinkles when clothing is placed on both sides.
[0029] Meanwhile, the power bank body 1 has a data cable at its interface. The data cable includes a main connector 8 that connects to the power bank body 1 interface and multiple auxiliary connectors 9 that connect to other devices with different interfaces, so that one power bank can be used with multiple different devices.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
