Description

Technical Field

[0001] This utility model belongs to the field of charger technology, and in particular relates to a portable magnetic charger. Background Technology

[0002] In today's era of widespread digitalization and electronic devices, batteries are used very frequently as a key energy supply component for various portable electronic devices. AA and AAA batteries, with their moderate size and suitable power reserve, have become the two most widely used battery specifications on the market and occupy an indispensable position in many consumer electronics products. However, as electronic devices become increasingly feature-rich and diverse, users' charging needs for batteries are growing and becoming more complex. Although there are various battery chargers on the market, most of them have many inconveniences, causing many problems for users' charging experience. On the one hand, existing chargers have serious shortcomings in terms of compatibility; many chargers are designed to be single and can only charge batteries of a specific size. For example, some chargers can only charge AA batteries, while others can only be used with AAA batteries. This means that if users have devices that use both types of batteries, they need to prepare at least two different types of chargers, which not only increases the purchase cost but also takes up more storage space and is extremely inconvenient to carry when traveling. On the other hand, the ease of operation and stability during the charging process also urgently need improvement. Some chargers are not structurally well designed. When users put the battery into the charger, the connection between the battery and the charging interface is often not stable enough, which can easily lead to poor contact. For example, during the charging process, the battery may separate from the charging interface due to slight vibration or shaking, causing the charging to be interrupted. Users need to readjust the battery position, which not only affects the charging efficiency but may also damage the battery and charger due to frequent plugging and unplugging. In addition, some chargers are cumbersome to adjust to accommodate batteries of different lengths, requiring tools or complicated steps to complete. This is very inconvenient for ordinary users. Therefore, we propose a portable magnetic charger to solve the problems mentioned above. Utility Model Content

[0003] In view of this, in order to solve the problems of poor compatibility, insufficient convenience and stability of charging operation of existing chargers, this utility model provides a portable magnetic charger.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a portable magnetic charger, including a USB socket for electrical connection to an external power adapter, wherein two wires are symmetrically connected to the USB socket, and a positive charging shell and a negative charging shell are respectively fixedly installed at one end of the two wires. The positive charging shell and the negative charging shell are respectively used for electrical connection to the positive and negative contacts of a AA battery. The magnetic charger also includes: A connecting component is connected to the positive charging shell and the negative charging shell respectively. The connecting component is used to support and connect the positive charging shell and the negative charging shell to maintain the sliding connection between the positive charging shell and the negative charging shell. The adapter is attracted to the positive and negative charging cases respectively, and is used to electrically connect to the positive and negative terminals of the AAA battery.

[0005] Furthermore, conductive sheets are fixedly installed on one inner wall of the positive charging shell and one inner wall of the negative charging shell, and one end of each of the two wires extends into the positive charging shell and the negative charging shell respectively and is electrically connected to the two conductive sheets respectively.

[0006] Furthermore, the connecting component includes a connecting rail fixedly installed on one side of the positive charging shell, a limiting slider slidably connected inside the connecting rail, a connecting rod fixedly installed on one side of the opening of the connecting rail, and one end of the connecting rod extending to the outside of the connecting rail and fixedly connected to one side of the negative charging shell.

[0007] Furthermore, a limiting rod is fixedly installed inside the connecting guide rail. The limiting rod passes through the limiting slider and is slidably connected to the limiting slider. A tension spring is sleeved on the limiting rod and located on one side of the limiting slider. The two ends of the tension spring are fixedly connected to one side of the inner wall of the connecting guide rail and one side of the limiting slider, respectively.

[0008] Furthermore, an adjustment hole is provided on the top inner wall of the connecting guide rail, and a lever is fixedly installed on the top of the limiting slider. The top of the lever passes through the adjustment hole and extends to the top of the connecting guide rail.

[0009] Furthermore, the adapter includes two extended docking shells, which are used to wrap the positive and negative terminals of the AAA battery, respectively. The two extended docking shells are symmetrically arranged, and magnetic conductive plates are fixedly installed on the opposite sides of the two extended docking shells. The opposite sides of the two magnetic conductive plates extend into the positive and negative charging shells and are attracted to the two conductive plates, respectively. A contact plate is provided on the inner wall of one side of the extended docking shell. The contact plate is electrically connected to the corresponding magnetic conductive plate, and the two contact plates are electrically in contact with the positive and negative terminals of the AAA battery, respectively.

[0010] The embodiments of this utility model have the following beneficial effects: 1. Through the set connecting parts, after the positive and negative terminals of the AA battery are inserted into the positive and negative charging cases respectively, the positive and negative terminals of the AA battery can be electrically contacted with two conductive plates respectively, thereby enabling the positive and negative terminals of the AA battery to be electrically connected to two wires respectively, thus realizing the charging of the AA battery. 2. With the adapter component, when charging a AAA battery, first insert the magnetic guide plates on the two extended docking shells into the positive and negative charging shells respectively, so that the two magnetic guide plates are tightly attracted to the two conductive plates. This allows the magnetic guide plates to make electrical contact with the conductive plates. Then, after adjusting the distance between the positive and negative charging shells to fit the length of the AAA battery, insert the positive and negative terminals of the AAA battery into the extended docking shells connected to the positive and negative charging shells respectively, so that the positive and negative terminals of the AAA battery are electrically connected to the two connecting plates respectively. This allows the positive and negative terminals of the AAA battery to be electrically connected to the conductive plates located in the positive and negative charging shells respectively, so that the AAA battery can be charged with an external power adapter. This invention solves the problem of poor compatibility of existing chargers, enabling it to charge both AA and AAA batteries, reducing purchase costs, saving space, and making it easy to carry. Furthermore, the battery and interface are firmly connected during charging, and adjusting the distance between the positive and negative charging shells is simple, avoiding poor contact and frequent plugging and unplugging, thus improving charging efficiency and extending the lifespan of the device.

[0014] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0015] Example 1: Please refer to Figures 1-5 As shown, this embodiment provides a portable magnetic charger, including a USB socket 1, which is used to electrically connect to an external power adapter to obtain electrical energy. Two wires 2 are electrically connected symmetrically to the USB socket 1. One end of each wire 2 is fixedly mounted with a positive charging case 3 and a negative charging case 4, respectively, which are used to electrically connect to the positive and negative contacts of a AA battery.

[0016] like Figure 5 As shown, conductive plates 14 are fixedly installed on one inner wall of the positive charging shell 3 and one inner wall of the negative charging shell 4. One end of each of the two wires 2 extends into the interior of the positive charging shell 3 and the negative charging shell 4, respectively, and is electrically connected to the two conductive plates 14. When the positive and negative terminals of the AA battery are inserted into the positive charging shell 3 and the negative charging shell 4, respectively, the positive and negative terminals of the AA battery can make electrical contact with the two conductive plates 14, thereby electrically connecting the positive and negative terminals of the AA battery to the two wires 2, completing the charging preparation work for the AA battery.

[0017] like Figure 3As shown, the connecting component is used to support and connect the positive charging shell 3 and the negative charging shell 4 to maintain their sliding connection. Specifically, a connecting guide rail 5 is fixedly installed on one side of the positive charging shell 3, and a limiting slider 7 is slidably connected inside the connecting guide rail 5. A connecting rod 8 is fixedly installed on one side of the opening of the connecting guide rail 5, with one end of the connecting rod 8 extending to the outside of the connecting guide rail 5 and fixedly connected to one side of the negative charging shell 4. By fixing the connecting guide rail 5 to the positive charging shell 3 and sliding the limiting slider 7 to the connecting guide rail 5, sliding support for the negative charging shell 4 is achieved. This ensures that the negative charging shell 4 moves linearly when moved, keeping the positive charging shell 3 and the negative charging shell 4 always on the same straight line, thus allowing the distance between the positive charging shell 3 and the negative charging shell 4 to be adjusted according to the length of an AA or AAA battery.

[0018] like Figure 3 As shown, a limiting rod 6 is fixedly installed inside the connecting guide rail 5. The limiting rod 6 passes through the limiting slider 7 and is slidably connected to the limiting slider 7. A tension spring 9 is sleeved on the limiting rod 6, located on one side of the limiting slider 7. The two ends of the tension spring 9 are fixedly connected to one side of the inner wall of the connecting guide rail 5 and one side of the limiting slider 7, respectively. By using the limiting rod 6 passing through the limiting slider 7, the limiting slider 7 can be laterally slidably supported, preventing the limiting slider 7 from moving out of the connecting guide rail 5. When the negative charging shell 4 is moved away from the positive charging shell 3, the limiting slider 7 will move simultaneously with the negative charging shell 4, thereby stretching the tension spring 9 and increasing the elastic potential energy of the tension spring 9. At this time, the elastic force of the tension spring 9 will cause the negative charging shell 4 to have a tendency to move in the opposite direction. Therefore, when charging the AA battery, the positive charging shell 3 and the negative charging shell 4 can generate a clamping force on the AA battery, ensuring that the positive and negative terminals of the AA battery are in close contact with the two conductive sheets 14, respectively.

[0019] like Figure 2 As shown, an adjustment hole 10 is provided on the top inner wall of the connecting guide rail 5, and a lever 11 is fixedly installed on the top of the limiting slider 7. The top of the lever 11 passes through the adjustment hole 10 and extends above the connecting guide rail 5. By pushing the lever 11 laterally, the limiting slider 7 can be moved, thereby facilitating the adjustment of the position of the negative charging shell 4.

[0020] This invention can be used in the field of charger technology, and can also be applied to other fields.

[0021] Example 2: This example is a further improvement on the previous example: as follows Figures 1-5As shown, a portable magnetic charger, applicable to the field of charger technology, includes an adapter component for electrically connecting to the positive and negative terminals of a AAA battery. The adapter component includes two extended docking shells 12, which respectively enclose the positive and negative terminals of the AAA battery and are symmetrically arranged. Magnetic conductive plates 13 are fixedly installed on the opposite sides of each of the two extended docking shells 12. These plates extend into the positive charging shell 3 and the negative charging shell 4, respectively, and are attracted to two conductive plates 14. A contact plate is provided on the inner wall of one side of each extended docking shell 12, electrically connected to the corresponding magnetic conductive plate 13. The two contact plates are in electrical contact with the positive and negative terminals of the AAA battery, respectively. When charging a AAA battery, first insert the magnetic guide plates 13 on the two extended docking shells 12 into the positive charging shell 3 and the negative charging shell 4, respectively, so that the two magnetic guide plates 13 are tightly attracted to the two conductive plates 14, achieving electrical contact between the magnetic guide plates 13 and the conductive plates 14. Then, adjust the distance between the positive charging shell 3 and the negative charging shell 4 by pushing the dial 11 to adapt to the length of the AAA battery. Finally, insert the positive and negative terminals of the AAA battery into the extended docking shells 12 connected to the positive charging shell 3 and the negative charging shell 4, respectively, so that the positive and negative terminals of the AAA battery are electrically connected to the two connecting plates, and thus electrically connected to the conductive plates 14 located in the positive charging shell 3 and the negative charging shell 4, respectively, and charge the AAA battery with an external power adapter.

[0022] Working principle: In use, first connect the USB socket 1 to the external power adapter to power the entire magnetic charger. To charge AA batteries, directly insert the positive and negative terminals of the AA battery into the positive charging case 3 and negative charging case 4 respectively, so that the positive and negative terminals of the AA battery make electrical contact with the conductive plates 14 inside the positive charging case 3 and negative charging case 4 respectively, and then connect electrically with the wire 2 to achieve charging. During the insertion of the AA battery, the limiting rod 6 inside the connecting guide rail 5 passes through the limiting slider 7 and slides, and the limiting slider 7 is connected to the limiting slider 7. The connecting rod 8 is connected to the negative charging shell 4. The movement of the negative charging shell 4 causes the limiting slider 7 to slide within the connecting guide rail 5. The tension spring 9 is stretched to generate elastic potential energy. Its elastic force is used to make the positive charging shell 3 and the negative charging shell 4 clamp the AA battery, ensuring that the positive and negative terminals of the AA battery are in close contact with the conductive sheet 14. When it is necessary to adjust the distance between the positive charging shell 3 and the negative charging shell 4 to accommodate batteries of different lengths, the dial 11 is pushed horizontally. The dial 11 causes the limiting slider 7 to move within the connecting guide rail 5, thereby changing the position of the negative charging shell 4. To charge a AAA battery, first insert the magnetic guide plates 13 on the two extended docking shells 12 into the positive charging shell 3 and the negative charging shell 4 respectively, so that the magnetic guide plates 13 and the conductive plates 14 are tightly attracted to achieve electrical contact. Then, adjust the distance between the positive charging shell 3 and the negative charging shell 4 by pushing the dial 11 to fit the length of the AAA battery. Then insert the positive and negative terminals of the AAA battery into the extended docking shells 12 connected to the positive charging shell 3 and the negative charging shell 4 respectively, so that the positive and negative terminals of the AAA battery are electrically connected to the contact plates in the extended docking shells 12, and then electrically connected to the conductive plates 14. Charge the AAA battery with an external power adapter.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
