[0002] AA (size 5) and AAA (size 7) batteries are the most common standardized cylindrical batteries in daily life. They are versatile, portable, have a stable voltage (1.5V), and are easy to replace. Due to their large capacity, AA and AAA batteries (hereinafter collectively referred to as batteries) are often used in devices with moderate power consumption, such as remote controls, wireless mice, toys, flashlights, and small electronic scales. Some types are also rechargeable, meeting emergency needs and reducing long-term costs through reusability. They are widely used in household electronics, office equipment, and children's toys.

[0003] To facilitate battery charging, a charging compartment is required. The charging compartment is connected to an external power source and has several battery placement slots 11. After placing the batteries in the battery placement slots 11 in sequence, the charging compartment is connected to an external power source to achieve the purpose of charging the batteries. The operation is simple.

[0004] Typically, the power cord of this type of charging case is directly connected to the charging case (i.e., the power cord and the charging case are not detachable), or the charging case and the power cord are detachably connected via a connector. Therefore, after the charging case is manufactured, it needs to be packaged in a box or other packaging materials to facilitate transportation or storage, and to protect both the charging case and the power cord. If the power cord is not properly stored after use, there is a risk of loss or damage, indicating room for improvement. Utility Model Content

[0013] Preferably, the size of the hanging member is smaller than the size of the cavity.

[0014] By adopting the above technical solution, when the hanging part is removed from the box, since the size of the hanging part is smaller than the size of the cavity, the hanging part after being removed from the box can be placed in the cavity, thus achieving the purpose of sustainable use of the hanging part.

[0015] Preferably, the cover is a transparent cover, and a labeling area is provided on the cover located in the cavity.

[0016] By adopting the above technical solution, the transparent lid allows consumers to observe the inside of the box in real time, making it easier for them to make a purchase. In addition, the labeling area on the lid makes it easy to distinguish the model.

[0017] Preferably, the box body has a guide portion circumferentially provided, the guide portion is used to guide the cover to close onto the box body, and the tolerance fit between the guide portion and the cover body is a transition fit.

[0018] By adopting the above technical solution, since the tolerance fit between the guide part and the cover is a transition fit, the cover has a certain damping feel when it is opened along the box, which improves the stability when the cover and the box are closed together, and also makes it easier for consumers to open the cover along the box.

[0019] Preferably, when the cover is closed onto the box, the connection between the cover and the box is flush.

[0020] By adopting the above technical solution, the connection between the lid and the box is made relatively smooth, improving the appearance quality when the lid is closed on the box.

[0021] Preferably, the housing is provided with a Type-C interface.

[0022] By adopting the above technical solution, the Type-C interface facilitates the compatibility of the doctor's battery charging case, eliminating the need for a dedicated power cable to connect to the case.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the battery does not need to be charged, close the cover to the box so that the power cord can be neatly stored in the cavity. At the same time, when the battery needs to be charged, close the cover to the box to protect the battery during charging and reduce the probability of short circuits caused by conductive objects coming into contact with the battery electrodes during charging.

[0025] 2. The fastening and disassembly of the hanging parts along the box can be achieved through the cooperation of the snap-fit ​​slot and snap-fit ​​part. The mechanical structure is simple and the stability is high.

[0026] 3. Because the tolerance fit between the guide part and the lid is a transition fit, the lid has a certain damping feel when it is opened along the box, which improves the stability when the lid and the box are closed together, and also makes it easier for consumers to open the lid along the box.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a charging box for AA or AAA batteries. (See also...) Figure 1 and Figure 2 A charging case for AA or AAA batteries includes a case body 1, which is used to place and charge the batteries. The case body 1 has a cavity 2 for storing the power cord. A cover 3 is detachably provided on the case body 1 for closing the case body 1.

[0033] Specifically, the box body 1 has several battery placement slots 11. The specific number of battery placement slots 11 can be increased or decreased according to actual needs and the actual size of the box body 1. Since the function of the several battery placement slots 11 is to place rechargeable batteries, their specific number is not limited here.

[0034] Furthermore, the size of the battery placement position 11 can be changed according to the battery model (e.g., AA and AAA batteries). Since the main components are the same, the actual size of the battery placement position 11 is not limited here.

[0035] Meanwhile, a positive electrode spring and a negative electrode spring are installed in the battery placement position 11, which are used to connect to the positive and negative terminals of the battery, respectively. The specific charging method is existing technology and will not be described in detail here.

[0036] Correspondingly, preferably, in this embodiment, the box 1 is provided with a Type-C interface 9 to adapt to the power cord connection method of mainstream electronic devices. When consumers need to charge the battery, they can also use a power cord that is compatible with the Type-C interface 9 to power the box 1, which has high compatibility.

[0037] Meanwhile, in other embodiments, the housing 1 can be powered by a USB-C interface.

[0038] Therefore, when the battery does not need to be charged, the cover 3 is closed on the box 1, so that the power cord can be neatly stored in the cavity 2. At the same time, when the battery needs to be charged, the cover 3 is opened, the power cord is taken out along the cavity 2, the battery is placed in the box 1, and the cover 3 is closed on the box 1. This achieves the purpose of protecting the battery during charging and reduces the probability of short circuits caused by conductive objects coming into contact with the battery electrodes during charging.

[0039] Furthermore, the cover 3 is a transparent cover, and a labeling area 7 is provided on the cover 3 located in the cavity 2. The cover 3 can be made of a light-transmitting material (such as plastic or acrylic sheet), so that when the cover 3 is closed on the box 1, the consumer can directly observe the actual situation inside the cavity 2 and / or the battery placement position 11 through the cover 3. Moreover, the labeling area 7 can be used to identify the model of the current battery charging box or other information (such as charging voltage, current, etc.) so that consumers can understand it more intuitively.

[0040] Reference Figure 1 and Figure 2 The box body 1 has a guide part 8 in a circumferential direction. The guide part 8 is used to guide the cover 3 to close onto the box body 1. The tolerance fit between the guide part 8 and the cover 3 is a transition fit.

[0041] Specifically, the guide part 8 and the box body 1 can be integrally molded by injection molding. The term "transition fit" is a mechanical term used to describe the tolerance fit relationship between components.

[0042] Therefore, because the tolerance fit between the guide part 8 and the cover 3 is a transition fit, the cover 3 has a certain damping feel when opened along the box body 1, improving the stability of the cover 3 and the box body 1 when they are closed, and also making it easier for consumers to open the cover 3 along the box body 1. The specific shape of the guide part 8 can be optimized according to the design of the box body 1, such as using an arc or trapezoidal structure to enhance the guiding effect. In addition, the bottom of the box body 1 is equipped with an anti-slip pad to ensure that the box body 1 is stable and does not slide during charging, further improving the safety of use. The edges of the cover 3 are designed with rounded corners to prevent fingers from being scratched during use.

[0043] At the same time, when the lid 3 is closed on the box 1, the connection between the lid 3 and the box 1 is flush, resulting in a neat and beautiful appearance. This improves the smoothness of the connection between the lid 3 and the box 1, reduces the accumulation of dust and dirt, facilitates cleaning and maintenance, and enhances the appearance quality of the lid 3 when it is closed on the box 1.

[0044] Reference Figure 2 and Figure 3 The box body 1 is detachably equipped with a hanging part 4. When the box body 1 needs to be stored or hung, the hanging part 4 can be installed on the box body 1. At the same time, when the box body 1 does not need to be stored or hung, the hanging part 4 can be removed along the box body 1. It is easy to operate and highly practical.

[0045] In this embodiment, preferably, the box body 1 has a snap-fit ​​groove 5, and the hanging member 4 has a snap-fit ​​part 6, with the snap-fit ​​groove 5 and the snap-fit ​​part 6 engaging in a snap-fit ​​cooperation. The snap-fit ​​groove 5 is formed by a recess in the side wall of the box body 1. Through the cooperation of the snap-fit ​​groove 5 and the snap-fit ​​part 6, the hanging member 4 can be quickly attached and detached along the box body 1, resulting in a simple mechanical structure and high stability.

[0046] Meanwhile, a locking baffle 10 is provided inside the snap-fit ​​groove 5. When the snap-fit ​​part 6 is placed inside the snap-fit ​​groove 5 and a force is applied to the hanging member 4, the snap-fit ​​part 6 is driven to rotate along the snap-fit ​​groove 5 until the snap-fit ​​part 6 abuts against the locking baffle 10. This indicates that the snap-fit ​​part 6 and the snap-fit ​​groove 5 are fully engaged, ensuring that the hanging member 4 is stable and not easy to fall off, thus improving the safety of use. The locking baffle 10 is ingeniously designed, which not only ensures the stability of the hanging member 4, but also simplifies the disassembly and assembly process, making it more convenient and efficient for consumers to use.

[0047] Meanwhile, the hanging part 4 has an opening, so when the battery charging box is not needed or when the supermarket needs to sell the battery charging box, the battery charging box can be hung in a designated location by the buckle. The operation is simple and does not require the use of other parts to place the battery charging box, which improves space utilization efficiency and meets diverse usage needs.

[0048] Correspondingly, the size of the hanging part 4 is smaller than the size of the cavity 2. When the hanging part 4 is removed from the box body 1, since the size of the hanging part 4 is smaller than the size of the cavity 2, the hanging part 4 that has been removed from the box body 1 can be placed in the cavity 2, so as to achieve the purpose of sustainable use of the hanging part 4.

[0049] In addition, in other embodiments, the hanging member 4 can be connected to the box body 1 by means of a snap or magnetic attraction, which enhances the stability of the hanging member 4, simplifies the disassembly and assembly steps, and improves the user experience.

[0050] The implementation principle of an AA or AAA battery charging box according to this application embodiment is as follows: When the battery does not need to be charged, the cover 3 is closed on the box body 1, so that the power cord can be well stored in the cavity 2. At the same time, when the battery needs to be charged, the cover 3 is closed on the box body 1, thereby achieving the purpose of protecting the battery during charging and reducing the probability of short circuits caused by conductive objects coming into contact with the battery electrodes during charging. Meanwhile, through the cooperation of the snap-fit ​​groove 5 and the snap-fit ​​part 6, the hanging part 4 can be quickly installed and removed along the box body 1. The mechanical structure is simple and highly stable.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
