Description

Technical Field

[0001] This utility model relates to the field of battery charging equipment technology, and more specifically, to a household battery charging case. Background Technology

[0002] Rechargeable batteries are widely used due to their advantages such as being environmentally friendly, economical, having sufficient power, and being reusable. Currently, chargers for rechargeable batteries on the market typically use the elasticity of a compression spring to secure the battery during charging. For example, Chinese Patent Publication No. CN215378499U discloses a reusable dry cell battery charging device, including a base. One end of the upper surface of the base is fixedly connected to a first fixing plate, and the other end is fixedly connected to a second fixing plate. An adjustment plate and an arc-shaped limiting groove are provided between the first and second fixing plates. A compression spring is provided between the second fixing plate and the adjustment plate. The dry cell battery is secured during charging through the arc-shaped limiting groove and the compression spring.

[0003] Similar to the battery charging box mentioned above, the rechargeable battery is fixed in place by the elasticity of a compression spring after being placed in the limiting slot. This means that when the battery needs to be removed, the spring must be compressed again from the limiting slot to take it out, or the battery can be pried out directly, which is quite inconvenient in practical applications.

[0004] Furthermore, battery charging cases like the one mentioned above have limited disposable charging points, making it impossible to charge multiple batteries simultaneously. Moreover, once charged, if multiple batteries are not needed at the same time, there are many issues regarding battery storage and portability. Utility Model Content

[0005] This utility model provides a household battery charging case with a box structure consisting of a bottom shell and a top cover. Whether placing or removing batteries, there is no need to align the spring to press and fix them or lift them out.

[0013] Preferably, the bottom shell is further provided with an elastic transmission element, which is disposed on the lower surface of the negative electrode contact plate.

[0014] Optionally, one side of the lower end of the cover is a fixed connection side, which is hinged to the housing via a pivot, and the opposite side of the fixed connection side is attracted and fixed to the housing via a magnetic attraction component.

[0015] Optionally, one side of the lower end of the cover is a fixed connection side, which is hinged to the housing via a pivot, and the opposite side of the fixed connection side is attracted and fixed to the housing via a fastener.

[0016] Compared with existing technologies, the household battery charging case of this utility model is designed as a box structure with a bottom shell and a top cover. The bottom shell and the top cover together form a receiving cavity. The bottom shell is provided with a negative contact plate for connecting the control board, and the top cover is provided with a positive contact plate on its closing surface. When charging a rechargeable battery, simply place the battery into the charging slot of the receiving cavity and close the top cover. The positive and negative terminals of the battery will then contact the corresponding charging points for charging. Since the depth of the charging slot is less than the length of the rechargeable battery, the battery can be easily removed by simply opening the top cover after charging. This household battery charging case is very convenient to use. Whether placing or removing the battery, there is no need to align the spring to press and fix it or lift it. It can also charge and store multiple batteries at the same time, making it easy to carry. Attached Figure Description

[0023] like Figures 1 to 5 The image shows an embodiment of the household battery charging case of this utility model. (As shown...) Figure 1 and Figure 2As shown, the household battery charging case includes a housing 10, a bottom shell 20, and a top cover 30. The bottom shell 20 is located below the housing 10, forming a receiving cavity 11 with the housing 10. The top cover 30 is mounted on the housing 10 in a relatively openable manner, and the top cover 30 is positioned opposite to the bottom shell 20. The top cover 30 has a positive electrode contact plate 31 on its closing surface. The housing 10 has a charging interface 12 that is electrically connected to a power source. The bottom shell 20 has a control board (not shown) and a negative electrode contact plate 21. The receiving cavity 11 is divided into several charging slots 111 for placing rechargeable batteries 40. The depth of each charging slot 111 is less than the length of the rechargeable battery 40. The bottom of each charging slot 111 is connected to the negative electrode contact plate 21. The charging interface 12, the control board, the negative electrode contact plate 21, and the positive electrode contact plate 31 are electrically connected sequentially.

[0024] When the rechargeable battery 40 needs to be charged, the bottom shell 20 and the housing 10 form a receiving cavity 11. The bottom shell 20 is provided with a negative contact plate 21 for connecting to the control board, and the cover 30 is provided with a positive contact plate 31 on its closing surface. Therefore, it is only necessary to place the battery 40 into the charging slot 111 and then close the cover 30. At this time, the two poles of the rechargeable battery 40 are electrically connected to the positive contact plate 31 and the negative contact plate 21 respectively, thereby charging. That is, this household battery charging case is designed as a box structure with a bottom shell 20 and a cover 30. The rechargeable battery 40 can be placed directly into it without the need for pressing springs to fix the battery as in traditional battery charging cases. It is understood that the depth of the box structure should be equivalent to the length of the rechargeable battery 40 so that the positive and negative poles of the battery 40 can contact the two contact plates inside the box structure after the cover 30 is closed. Furthermore, since the depth of the charging slot 111 is less than the length of the rechargeable battery 40, once the rechargeable battery 40 is fully charged, it can be easily removed by simply opening the cover 30. Even when multiple batteries are needed, they can all be removed directly, which is very convenient. This household battery charging compartment is extremely convenient to use. Whether placing or removing batteries, there is no need to align the springs for pressing or lifting, allowing for simultaneous charging of multiple batteries and facilitating battery storage and portability.

[0025] like Figure 1 , Figure 2As shown, the positive contact plate 31 has a plurality of positive contact points 311, and the negative contact plate 21 has a plurality of negative contact points 211. The number of positive contact points 311 and the number of negative contact points 211 are equal to the number of charging slots 111. When the cover 30 is closed on the housing 10, each charging slot 111 has one positive contact point 311 and one negative contact point 211 respectively arranged above and below. The charging slots 111 divided by the receiving cavity 11 can be designed according to actual use, such as being divided into four AAA battery slots and four AA battery slots, etc., simply by arranging the positive contact point 311 and the negative contact point 211 respectively above and below each charging slot 111.

[0026] To prevent the battery from shaking in the charging slot 111 and affecting the charging effect, such as Figure 3 As shown, a support 13 is also provided inside the receiving cavity 11. The support 13 has limiting holes 131 that correspond one-to-one with the number of charging slots 111. The diameter of the limiting holes 131 is slightly larger than the cross-sectional diameter of the rechargeable battery 40. When the rechargeable battery 40 is placed, the battery 40 can be placed into the charging slot 111 through the limiting holes 131, which can improve the convenience and accuracy of charging the battery 40.

[0027] In the improved embodiment, the bracket 13 can be detachably fixed to the housing 10, meaning the receiving cavity 11 can also be adjusted to accommodate the size and number of batteries 40 to be charged. Figure 3 and Figure 4 As shown, the inner wall of the housing 10 is provided with a locking position 112, and the bracket 13 is provided with a buckle position 132. The bracket 13 is fixedly connected to the housing 10 through the buckle position 132 and the locking position 112.

[0028] In the improved embodiment, the bracket 13 and the charging slot 111 are integrally formed, which can further prevent shaking or collision between the rechargeable batteries 40, such as... Figure 4 As shown, the inner wall of the housing 10 is provided with several ribs 113, and each rib 113 is arranged between two charging slots 111, thereby improving the overall structural stability.

[0029] As an improvement to the above embodiments, such as Figure 5 As shown, an indicator light 32 electrically connected to the control board can also be provided on the upper surface of the cover 30. The indicator light 32 is set one-to-one with the positive contact point 311. When the rechargeable battery 40 is charging or has completed charging, the indicator light 32 can perform a corresponding reminder action. In addition, an elastic transmission member (not shown) is also provided on the bottom shell 20. The elastic transmission member is set on the lower surface of the negative contact plate 21, so that when the cover 30 is closed, the charging contact points of the two poles of the rechargeable battery 40 can be further stabilized.

[0030] In the embodiments of this utility model, such as Figure 2 and Figure 3 As shown, one side of the lower end of the cover 30 is a fixed connection edge 301. The fixed connection edge 301 is hinged to the housing 10 via a pivot 33. The opposite edge 302 of the fixed connection edge 301 is attracted and fixed to the housing 10 via a magnetic suction member 34. The opposite edge 302 of the fixed connection edge 301 can also be attracted and fixed to the housing 10 via a fastener, which is convenient for opening and closing and can prevent the rechargeable battery 40 from falling out.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
