Description

Technical Field

[0001] This utility model belongs to the field of charger technology, and in particular relates to an integrated battery charging box. Background Technology

[0002] With the widespread use of electronic devices, the use of various types of batteries as their power source is increasing day by day. Among them, AA batteries and AAA batteries occupy an important position in daily life and many small electronic devices (such as remote controls, toys, flashlights, etc.) due to their wide range of applications.

[0003] However, there are many shortcomings in the charging devices for these two types of batteries on the market. On the one hand, most existing battery charging devices are single-function and can usually only charge one type of battery. They cannot meet the charging needs of both AA and AAA batteries at the same time. When users have batteries of different specifications that need to be charged, they need to be equipped with multiple different charging devices, which not only increases the cost of use but also takes up a lot of space and causes inconvenience to users.

[0004] On the other hand, the existing charging devices are not well designed. During the charging process, the connection between the battery and the charging contacts is not stable. It is easy for slight shaking or vibration to cause poor contact, which affects the charging effect and may even result in the inability to charge. Moreover, some charging devices lack effective positioning and fixing structures, making it difficult to accurately align the positive and negative terminals of the battery with the charging contacts when placing the battery, which increases the difficulty of use and reduces the charging efficiency.

[0005] Therefore, we propose an integrated battery charging box to address the aforementioned problems. Utility Model Content

[0006] In view of this, in order to solve the problems of limited functionality, poor connection stability and difficulty in positioning of existing charging devices, this utility model provides an integrated battery charging box.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated battery charging box, including a charging box bottom compartment, a bottom cover snapped onto the bottom of the charging box bottom compartment, and a top cover hinged to the top of the charging box bottom compartment. A positive power supply board is fixedly installed inside the charging box bottom compartment, and multiple positive contacts are symmetrically arranged on the positive power supply board for electrical contact with the positive terminal of the battery. A slot is fixedly installed through one side of the bottom inner wall of the charging box bottom compartment, and the slot is electrically connected to the positive power supply board. The charging box also includes:

[0008] A negative electrode energizing plate is set on the inner wall of the top of the cover. Multiple negative electrode contacts are symmetrically arranged on the negative electrode energizing plate. The negative electrode contacts make electrical contact with the corresponding negative electrode of the battery to achieve the purpose of charging the battery.

[0009] The battery support frame is located in the bottom compartment of the charging box. Multiple battery slots are symmetrically arranged on the battery support frame. The top of the battery support frame extends into the top cover and is engaged with the inner wall of the top cover. The battery slots are used to support AA or AAA batteries, so that the positive and negative terminals of the AA or AAA batteries make electrical contact with the corresponding positive and negative contacts, respectively, to achieve the purpose of charging the AA or AAA batteries.

[0010] Furthermore, a bracket is fixedly installed at the bottom of the battery support frame. The bracket is located inside the bottom compartment of the charging box and is engaged with the inner wall of the bottom compartment. Four positioning rods are symmetrically integrated on the battery support frame. Four positioning blind holes are symmetrically opened on the top inner wall of the top cover. The top of the positioning rod extends into the corresponding positioning blind hole and is engaged with the inner wall of the positioning blind hole.

[0011] Furthermore, a battery docking frame is also provided inside the battery slot. The battery docking frame is used to support the No. 7 battery. Multiple snap-fit ​​ribs are integrally provided at equal intervals on the outer side of the battery docking frame. The multiple snap-fit ​​ribs are tightly fitted to the inner wall of the battery slot. A power cap is fixedly installed on the top of the battery docking frame. The negative terminal of the No. 7 battery is in electrical contact with the power cap, and the top of the power cap is in electrical contact with the corresponding negative terminal contact.

[0012] Furthermore, the battery support frame is provided with a conductive rod, the positive power supply board is provided with an energized contact, and the negative power supply board is provided with an insertion slot. The bottom end of the conductive rod is electrically in contact with the energized contact, and the top end of the conductive rod extends into the insertion slot and is electrically connected to the inner wall of the insertion slot.

[0013] Furthermore, a heat dissipation copper plate is fixedly installed on the bottom inner wall of the bottom cover, and the top of the heat dissipation copper plate is hollow and wavy.

[0014] Furthermore, the charging box also includes a power adapter disposed on one side of the bottom compartment of the charging box. The power adapter is electrically connected to a wire, one end of which is electrically connected to a plug, and the plug is electrically inserted into a slot.

[0015] The embodiments of this utility model have the following beneficial effects:

[0016] 1. With the bracket and four positioning rods on the battery support frame, after the AA battery is inserted into the corresponding battery slot, the AA battery and the battery slot are kept in a tight fit. Then, the battery support frame containing the AA battery is placed in the bottom compartment of the charging box, and the bracket is locked into the bottom compartment of the charging box.

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.

[0031] Example 1: Please refer to Figures 1-8As shown, this embodiment provides an integrated battery charging box, including a charging box bottom compartment 1. A bottom cover 2 is snapped onto the bottom of the charging box bottom compartment 1, and a top cover 7 is hinged to the top of the charging box bottom compartment 1. A positive power supply board 4 is fixedly installed inside the charging box bottom compartment 1. Multiple positive contacts 6 are symmetrically arranged on the positive power supply board 4 for electrical contact with the positive terminal of an AA battery 20 or an AAA battery 21. A fixed mounting slot 5 passes through the bottom inner wall of one side of the charging box bottom compartment 1 and is electrically connected to the positive power supply board 4.

[0032] like Figure 4 As shown, a negative electrode energizing plate 8 is fixedly installed on the inner wall of the top of the cover 7. Multiple negative electrode contacts 9 are symmetrically arranged on the negative electrode energizing plate 8. The negative electrode contacts 9 make electrical contact with the negative electrode of the AA battery 20 or the energizing cap 19 to achieve the charging purpose.

[0033] like Figure 5-6 As shown, the charging box also includes a battery support frame 13 disposed in the bottom compartment 1 of the charging box. Multiple battery slots are symmetrically arranged on the battery support frame 13 to support AA batteries 20, ensuring that the positive and negative terminals of the AA batteries 20 make electrical contact with the corresponding positive contact 6 and negative contact 9, respectively. A bracket 12 is fixedly installed at the bottom of the battery support frame 13, located inside the bottom compartment 1 of the charging box and snapped into the inner wall. Four positioning rods 14 are symmetrically integrated on the battery support frame 13, and four positioning blind holes 15 are symmetrically opened on the inner wall of the top of the cover 7. The tips of the positioning rods 14 extend into the corresponding positioning blind holes 15 and are snapped into place. After the AA battery 20 is inserted into the corresponding battery slot and fits tightly, the battery support frame 13 containing the AA battery 20 is placed into the bottom compartment 1 of the charging box and secured by the bracket 12. The top cover 7 is flipped to close the charging box, and the positioning rod 14 is inserted into the positioning blind hole 15 to position the battery support frame 13, making it stable and not shaking inside the charging box. This ensures that the positive and negative terminals of the AA battery 20 are in stable contact with the corresponding positive and negative contacts 9, thus achieving charging.

[0034] like Figure 2 As shown, a conductive rod 16 is also provided on the battery support frame 13, an energizing contact 10 is provided on the positive power supply board 4, and a plug-in slot 11 is provided on the negative power supply board 8. The bottom end of the conductive rod 16 is in electrical contact with the energizing contact 10, and the top end of the conductive rod 16 extends into the plug-in slot 11 and is electrically plugged in. After the battery support frame 13 is placed in the bottom compartment 1 of the charging box, the conductive rod 16 is in electrical contact with the positive power supply board 4 through the energizing contact 10. Closing the top cover 7 allows the conductive rod 16 to be plugged into the plug-in slot 11, thus connecting the positive power supply board 4 and the negative power supply board 8, ensuring a stable current flow during charging.

[0035] A heat dissipation copper plate 3 is fixedly installed on the inner wall of the bottom of the bottom cover 2. The top of the heat dissipation copper plate 3 is hollow and wavy. When the positive power supply board 4 is powered on to charge the AA battery 20 or the AAA battery 21, it generates heat. The heat dissipation copper plate 3 absorbs the heat and keeps the positive power supply board 4 working stably.

[0036] The charging case also includes a power adapter 22 located on one side of the bottom compartment 1. The power adapter 22 has an electrically connected wire, one end of which is electrically connected to a plug. The plug is electrically inserted into a slot 5. When the plug is inserted into the slot 5, the power adapter 22 is connected to an external power strip. The power adapter 22 converts household electricity into low-voltage DC power and transmits it to the positive power supply board 4, facilitating the charging of AA batteries 20 or AAA batteries 21.

[0037] This invention can be used in the field of charger technology, and can also be applied to other fields.

[0038] Example 2: This example is a further improvement on the previous example: as follows Figures 6-8 As shown, an integrated battery charging box, applied in the field of charger technology, allows for charging of AAA batteries 21. A battery docking bracket 17 is installed within the battery compartment to support the AAA batteries 21. Multiple snap-fit ​​ribs 18 are integrally and evenly spaced on the outer side of the battery docking bracket 17, and these ribs 18 are tightly fitted to the inner wall of the battery compartment. A power-conducting cap 19, used for electrically connecting the negative terminal and negative contact 9 of the AAA battery 21, is fixedly installed on the top of the battery docking bracket 17. The negative terminal of the AAA battery 21 is electrically in contact with the power-conducting cap 19, and the top of the power-conducting cap 19 is electrically in contact with the corresponding negative contact 9. When charging the AAA battery 21, first insert the AAA battery 21 into the corresponding battery connector 17 so that the negative terminal is electrically connected to the power cap 19. Then insert the battery connector 17 into the corresponding battery slot from below the battery support frame 13. The connector is tightly inserted into the inner wall of the battery slot through the snap-fit ​​rib 18. After placing the battery support frame 13 and closing the top cover 7, the positive terminal of the AAA battery 21 is stably electrically connected to the corresponding positive terminal contact 6, and the power cap 19 is electrically connected to the corresponding negative terminal contact 9, thus realizing charging.

[0039] Working principle: When using, first operate according to the specifications of the battery to be charged. To charge AA battery 20, first insert AA battery 20 into the corresponding battery slot on the battery support frame 13, ensuring that AA battery 20 fits tightly with the battery slot. Then, put the battery support frame 13 into the bottom compartment 1 of the charging box, and fix it to the inner wall of the bottom compartment 1 of the charging box by the bracket 12 fixed at its bottom. Then, flip the top cover 7 to close the charging box. The top of the positioning rod 14 will insert into the corresponding positioning blind hole 15 on the inner wall of the top of the top cover 7 and lock in place, thereby positioning the battery support frame 13 and making it stable and not shaking in the charging box, ensuring that the positive and negative terminals of AA battery 20 are in stable contact with the positive contact 6 on the positive power supply board 4 and the negative contact 9 on the negative power board 8 on the inner wall of the top of the top cover 7, respectively.

[0040] To charge the AAA battery 21, first insert the AAA battery 21 into the battery connector 17, making the negative terminal of the AAA battery 21 electrically contact the power cap 19 fixed on the top of the battery connector 17. Then insert the battery connector 17 into the corresponding battery slot from below the battery support frame 13. The multiple snap-fit ​​ribs 18 on the outside of the battery connector 17 are tightly inserted and fixed to the inner wall of the battery slot. After that, put the battery support frame 13 into the bottom compartment 1 of the charging box and snap it in place. Close the top cover 7. This will also make the positive terminal of the AAA battery 21 electrically connected to the positive contact 6 and the power cap 19 electrically connected to the negative contact 9.

[0041] After the battery support frame 13 is placed into the bottom compartment 1 of the charging box, the bottom end of the conductive rod 16 fixed on it makes electrical contact with the power contact 10 on the positive power supply board 4. When the top cover 7 is closed, the top end of the conductive rod 16 extends into the plug slot 11 on the negative power supply board 8 and is electrically plugged in, thereby connecting the positive power supply board 4 and the negative power supply board 8. Then, the plug on the power adapter 22 is electrically plugged into the slot 5 fixedly installed through the bottom inner wall of one side of the bottom compartment 1 of the charging box. Then, the plug at the other end of the power adapter 22 is connected to the external power strip. The power adapter 22 converts household electricity into low-voltage DC electricity and transmits it to the positive power supply board 4. The current forms a circuit through the positive contact 6, the battery, and the negative contact 9 to charge the AA battery 20 or the AAA battery 21. During the charging process, the heat generated by the operation of the positive power supply board 4 is absorbed by the hollow, wave-shaped heat dissipation copper plate 3 fixedly installed on the bottom inner wall of the bottom cover 2, keeping the positive power supply board 4 working stably.

[0042] However, as is well known to those skilled in the art, the working principle and wiring method of the power adapter 22 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. 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.
