Double side battery charger

Double-sided battery charger

This creation is about the improvement of the structure and function of the charger. It refers to a double-sided battery charger that provides uniform sharing and charging of various types of batteries from different manufacturers.

Press, for the currently widely used electronic products, such as mobile phones, MP3, digital cameras, etc., are equipped with their own dedicated models of batteries, so as to have a high degree of mobility and convenience in use; in the case of mobile phones, almost every manufacturer The sizes of the batteries produced are not the same, and even the electrical contact points for charging are different (either on the bottom of the battery or on the side).

In the case of a commercially available or common charger, it is generally composed of a top cover and a base, and a charging circuit board with a plurality of conductive terminals, the upper cover having at least a specific shaped receiving groove for providing battery embedding The terminal slot is provided in the accommodating slot and the conductive terminal is exposed. When the battery is placed in the accommodating groove, the electrical contact point of the bottom surface or the side surface can contact the conductive terminal to be charged.

According to the above charger structure, since the size and shape of the accommodating groove are fixed, and the position of the conductive terminal in the accommodating groove is fixed and cannot be changed, it is not applicable to charging of the battery of other different sizes or different electrical contact points. The manufacturer or the manufacturer must separately mold and manufacture the charger mold for various types and sizes of batteries, and the cost is high and the situation is serious. In particular, up to now, all the batteries placed in the receiving slots of the charger have been placed directly without any clip design. Once slightly tilted or skewed, it may cause poor contact or even no electrical contact. .

In view of this, the creators of this case are aiming at the above-mentioned deficiencies and further research, and through continuous efforts, they will create an updated and more practical "double-sided battery charger", which will benefit the public.

The purpose of this creation is to provide a double-sided battery charger, thereby providing uniform charging of various types of batteries of different manufacturers, so as to achieve convenient charging effect for different types of batteries, thereby reducing costs and economic benefits.

In order to achieve the above objectives, a double-sided battery charger is designed, which comprises: a first base, a second base and a charging circuit board; respectively, a surface of the first and second bases is respectively provided to allow different manufacturers to manufacture A common storage slot for a plurality of types of batteries, wherein a plurality of torsion springs are disposed on each of the peripheral surface and the bottom surface, so as to apply corresponding contacts of various types of battery contact points, and a charging circuit is interposed between the first and second bases. The board is electrically connected to each of the torsion springs, so that various types of batteries embedded in the placement slots can be charged smoothly; thereby, the first and second bases of the double-sided battery charger are placed in use. The slot allows the battery to be charged to be inserted in a direction angle and engages the contact point with the torsion spring to achieve the charging effect, so that it can be used for charging various types of batteries of different manufacturers.

Moreover, the charging circuit board is further provided with an LED light to indicate a charging state, and a power socket to connect the external power input.

Moreover, the bottom surface of the common placement slot of the first base may be an inclined surface to provide the battery to be placed obliquely, thereby re-expanding the charging mode of the first base.

Moreover, a vertical placement slot is further disposed on the surface of the first base, and the battery is placed in an upright position, thereby re-expanding the charging mode of the second base.

The detailed description and technical content of this creation are as follows:

Please refer to the first and second figures for different angled views of the double-sided battery charger structure provided for the present invention. The structure of the double-sided battery charger (1) disclosed in a preferred embodiment includes: The first base (10) is provided with a common placement slot (11) on the surface that can accommodate different types or types of batteries, and a plurality of torsion springs (12) are disposed on each of the peripheral surface and the bottom surface. For the corresponding contact of various types of battery contact points; a second base (20), on the surface is also provided with a common placement slot (21) which can allow different types or types of batteries produced by one manufacturer, and each inner circumference And a plurality of torsion springs (22) are disposed on the bottom surface to suit corresponding contact of various types of battery contact points; a charging circuit board (30) is embedded between the first and second bases (10, 20), And the torsion springs (12, 22) are electrically connected by the line (31), so that various types of batteries embedded in the common placement slots (11, 21) can be charged smoothly; and the charging circuit board (30) is separately provided. There are LED lights (32) indicating the charging status, and the power jack (33) is used to connect the input of the external power supply.

Please refer to the third figure, which is a detailed structural diagram of a double-sided battery charger according to a preferred embodiment; wherein the double-sided battery charger (1) has a first base (10) on one side and a second base on the other side. The two bases (20), the common placement slots (11, 21) on the surfaces of the first and second bases (10, 20) can be independently selected according to the size of the battery (4) and the position of the electrical contact points. And use the power jack (33) to connect the power cord to input the external power to the double-sided battery charger (1), and the LED light can indicate whether the charging status is completed; thereby, in practical use, the user can selectively utilize the double The common storage slots (11, 21) of the first and second bases (10, 20) of the surface battery charger (1) are such that the battery to be charged (4) is selected to match the direction angle and the contact point is The torsion springs (12, 22) are in contact with each other to achieve the charging effect, so that it is suitable for charging operations of various types of batteries of different manufacturers.

Please refer to the fourth figure, which is a cross-sectional view of a double-sided battery charger in a preferred embodiment; wherein the inner bottom surface of the common seating groove (11) of the first base (10) may be an inclined surface (13). A torsion spring (12) is disposed on the side of the surrounding side to provide the battery (4) to be placed obliquely, and the electrical contact point is in contact with the torsion spring (12), thereby expanding the first base (10) The charging type; in addition, the surface of the second base (20) may further be provided with a vertical positioning groove (23), and a torsion spring (22) is disposed on the side around the bottom surface thereof, and the battery is provided ( 4) It is placed upright, and its electrical contact point can be in contact with the torsion spring (22), thereby re-expanding the charging pattern of the second base (20).

It can be seen from the above description that the common placement groove designed by the double-sided battery charger of the present invention is formed into a common type by using a plurality of sizes and shapes, and is matched with the battery of the peripheral surface, the bottom surface, the slope surface, and the like. There are a number of torsion springs at the location of the contact points, which can be applied to the charging of different types of batteries produced by different manufacturers, which will greatly reduce the cost and meet the economic benefits.
