Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and specifically, to a combined battery and a battery pack. Background Art

[0002] Dry batteries, also known as primary batteries, have a long development history and are also applied to fields such as flashlights, semiconductor radios, cassette recorders, cameras, electronic clocks, toys, etc. However, they also have extremely obvious drawbacks, that is, short service life and inability to be reused.

[0003] Lithium-ion batteries, also known as secondary batteries, are one of the new energy products. They have advantages such as long service life, high use stability, and low cost, and are also used in many fields.

[0004] Therefore, it will be a future trend for lithium-ion batteries to replace traditional dry batteries; however, since the voltage of lithium-ion batteries is much greater than the 1.5V voltage value of dry batteries, a step-down chip is usually used to step down the output of lithium-ion batteries to achieve an output value of 1.5V, thereby solving the problem of the output voltage value. Currently, lithium-ion batteries and step-down chips are connected by connecting straps or thimbles, and both of these connection methods will increase the resistance value and cause power loss.

[0029] Embodiment 1

[0030] As Figures 1 - 3 shown, Figure 1 is a schematic three-dimensional structure diagram of a combined battery; Figure 2 is a schematic cross-sectional diagram of a combined battery; Figure 3 is a schematic disassembled structure diagram of a combined battery. The combined battery includes a housing 1, an energy storage component 2, and a voltage regulating component 3. The energy storage component 2 is disposed in the housing 1, and the voltage regulating component 3 is electrically connected to the energy storage component 2, and the output voltage is adjusted through the voltage regulating component 3.

[0031] In specific applications, the housing 1 has a receiving groove 11, and both the energy storage component 2 and the voltage regulating component 3 are disposed in the receiving groove 11. Specifically, after the energy storage component 2 is placed in the receiving groove 11, the energy storage component 2 is electrically connected to the bottom of the receiving groove 11. The voltage regulating component 3 is located at the notch of the receiving groove 11. By pressing the edge of the notch inward for edge treatment, the edge of the notch is brought into contact with the voltage regulating component 3, and thus the energy storage component 2 and the voltage regulating component 3 can be fixed in the receiving groove 11.

[0032] The energy storage component 2 includes a battery body 21 and a conductor 22. Both the battery body 21 and the conductor 22 are located in the accommodation groove 11. One end of the conductor 22 is connected to the battery body 21, and the other end of the conductor 22 is connected to the voltage regulating component 3. In specific applications, the battery body 21 has a first polar end 211 and a second polar end 212. The second polar end 212 is electrically connected to the bottom of the accommodation groove 11, and the first polar end 211 is electrically connected to the conductor 22. Specifically, the battery body 21 is a lithium-ion battery, where the first polar end 211 is the positive electrode end and the second polar end 212 is the negative electrode end. Further, the conductor 22 can also be an integral structure with the first polar end 211 of the battery body 21. That is, when preparing the battery body 21, the conductor 22 is formed together, thus eliminating the connecting component between the battery body 21 and the voltage regulating component 3. By reducing the components in the transmission process, the resistivity is reduced, and at the same time, it is beneficial to improve its electrical conductivity.

[0033] The voltage regulating component 3 includes a circuit board 31 and an end cap 32. One side of the circuit board 31 facing the battery body 21 is electrically connected to one end of the conductor 22, and the end cap 32 is arranged on the side of the circuit board 31 away from the conductor 22. In specific applications, the electronic components on the circuit board 31 are integrated in the middle position of the circuit board 31, and the end cap 32 covers the integrated part of the electronic components to protect and conduct them. Specifically, the circuit board 31 can select an existing buck chip. The end cap 32 is made of a metal material, and the end cap 32 at the rear end of the circuit board 31 serves as the positive electrode of the combined battery.

[0034] Preferably, the combined battery further includes a metal part 4. The metal part 4 is located between the second polar end 212 of the energy storage component 2 and the bottom of the accommodation groove 11, that is, the metal part 4 is electrically connected to the second polar end 212 and the bottom of the accommodation groove 11. By setting the metal part 4, the contact area between the two can be increased, and the discharge rate can be provided. In this embodiment, the metal part 4 is a mesh structure; the metal part 4 is made of steel, aluminum or copper.

[0035] In summary, through the cooperation of the outer shell 1, the energy storage component 2 and the voltage regulating component 3, the conductor 22 of the energy storage component 2 is directly connected to the battery body 21 and the voltage regulating component 3, eliminating the remaining components between the battery body 21 and the voltage regulating component 3, reducing the resistance value in the current transmission process, avoiding power loss, and at the same time improving the electrical conductivity; in addition, it is beneficial to improve the stability of the overall structure of the combined battery.
