In order for those skilled in the art to better understand the structure of the battery plate provided by the embodiment of the present invention, a detailed structure of the battery tank is provided below, please refer to Figure 3 and Figure 4, which are schematic structural diagrams of a battery tank provided by the embodiment of the present invention .

FIG. 3 and FIG. 4 jointly illustrate the structure of a battery tank provided by an embodiment of the present invention.

Figure 3 shows the top view of the battery board, from which it can be seen that the corresponding battery in the battery slot has a maximum width of W and a maximum height of H, and Figure 3 also shows a cross-sectional view of the battery tank, from the cross-sectional view It can be seen that the maximum width of the battery is W, and the maximum thickness is D, and the battery interface contacts shown in Figure 1 are set on the groove wall 1014 in the sectional view: the positive contact 102, the negative contact 103 and the battery status contact. Point 104. Figure 4 shows the width, length and height of the largest battery that can be placed in the battery slot. The width of the battery is W, the thickness is D, and the height is H. Figure 4 also shows a schematic diagram of the battery structure where two batteries are placed , the heights of the two batteries are H1 and H2, the width is W1 (W1 is less than or equal to W), the thickness is D, and the sum of H1 and H2 is less than or equal to H, in practical applications, the width of the two batteries can be Not the same, as long as the width of the two batteries is less than or equal to W. Figure 4 also shows a schematic diagram of the battery structure where three batteries are placed, and the heights of the three batteries are H3, H4, and H5 respectively.

, where the sum of H3, H4 and H5 is less than or equal to H, and the width of these three batteries is W2, and W2 is less than or equal to W. Of course, the width of these three batteries can be unequal in practical applications, as long as the width of each battery is less than W is enough, and the thickness of these three batteries is D. In practical applications, the width of each battery can also be different, as long as the battery contacts in the battery can correspond to the battery interface contacts in the groove wall.

It is understandable that multiple batteries can be placed in the battery slot at the same time. If a battery is too low, other batteries with higher power may supply power to the battery with lower power, causing mutual loss between batteries. Therefore, a diode 501 can be arranged between the positive contact and the negative contact of each set of battery interface contacts, the anode of the diode 501 is connected to the positive contact 102 in the corresponding set of battery interface contacts, and the cathode of the diode is connected to the circuit The modules 502 are connected, and the other end of the circuit module 502 is connected to the negative contact 103 . Please refer to FIG. 5 , which is a schematic structural diagram of a circuit corresponding to each set of battery interface contacts in a battery panel provided by an embodiment of the present invention.

When the battery is working normally, that is, when powering electronic equipment, the current flows from the positive contact 102 to the negative contact 103. At this time, the diode 501 is turned on. The current of the low battery flows from the negative contact 103 to the positive contact 102, and the diode 501 is cut off at this time, so that mutual loss between the batteries can be avoided.

In practical applications, one or more diodes 501 can be arranged between the positive contact and the negative contact of each group of battery interface contacts, and when the battery normally supplies power to the circuit module 502 in the electronic device, the plurality of diodes 501 are all in a conduction state, and FIG. 5 only shows a schematic structural diagram of setting one diode 501 .

Please refer to FIG. 6 , which is a schematic structural diagram of another implementation of a circuit corresponding to each set of battery interface contacts in a battery panel provided by an embodiment of the present invention. The battery panel provided by the embodiment of the present invention may further include: a first mechanical switch S1 connected in series with the diode 501, a second mechanical switch S2 connected in parallel with the diode 501, and the second mechanical switch S2 connected in parallel with the diode 501 and connected with the first mechanical switch S1 in series.

In practical applications, sometimes it is necessary to force the battery with a higher capacity to supply power to the battery with a lower capacity. This can be done by closing the first mechanical switch S1 and closing the second mechanical switch S2. When a battery needs to be removed, the first mechanical switch S1 can be forcibly turned off, the first mechanical switch S1 can be a normally closed contact, and the second mechanical switch S2 can be a normally open contact.

The above-mentioned electronic device includes at least two batteries, and the above-mentioned battery slot can place the batteries. The battery board provided by the embodiment of the present invention can also include a processor, and the processor can control the battery-powered processor according to preset rules.

After the user places the battery in the battery slot, the processor can determine how many batteries are placed in the battery slot. If the battery interface contacts are arranged as shown in Figure 1, one battery corresponds to at least one set of battery interface contacts. The method for the processor to determine how many batteries are placed in the battery slot is as follows: After the user places the first battery in the battery slot, the processor first judges that a path is formed between several positive contacts and negative contacts (the path will be formed). The positive contacts are collectively referred to as the first positive contact, and the negative contacts forming the path are collectively referred to as the first negative contact), and the first positive contact and the first negative contact forming the path correspond to the first battery. After placing the second battery in the slot, judge whether the other positive contacts and negative contacts except the first positive contact and the first negative contact are conducting, and the positive contact and negative contact that are conducting at this time are called It is the second positive contact and the second negative contact. At this time, the second positive contact and the second negative contact correspond to the second battery. By analogy, the processor can know that the user has placed a total of A few batteries are gone. The processor registers the correspondence between the battery and the positive and negative contacts. Therefore, the function of the processor controlling the battery to supply power according to preset rules can be realized.
