Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As depicted in figs. 1 and 2, a kind of constant cell, including metal shell 1, battery core 2, first line plate
31, the second wiring board 32 and metal cap 4, the front end of metal shell 1 is provided with opening, and battery core 2 is by this
It is internal that opening is inserted into metal shell 1, and metal cap 4 is matched with the front opening of metal shell 1, this metal
Cap 4 connects metal shell 1 through an insulated enclosure circle 7, and two terminals of battery core 2 are respectively by wire even
It is connected on the second wiring board 32, first line plate 31 is provided with charging circuit and protection circuit, second
Being provided with step-up/step-down circuit on wiring board 32, this step-up/step-down circuit is used for: when battery core 2 voltage is higher than specified defeated
When going out voltage, battery core 2 output voltage is carried out blood pressure lowering process, when battery core 2 voltage is less than rated output voltage,
Battery core 2 output voltage is carried out boosting process.When battery core 2 voltage is higher than nominal constant output voltage, such as lithium
Electricity battery core, voltage is higher than 3.7V, then output procedure first carries out blood pressure lowering process, carries out steady after reaching rated voltage again
Fixed output；When battery core 2 voltage is less than nominal constant output voltage, such as ni-mh battery core, voltage is only
1.2V-1.4V, then output procedure first carries out boosting process, carries out stable output after reaching rated voltage again；First
Wiring board 31 and the second wiring board 32 are all built in metal shell 1, first line plate 31 and the second circuit
The positive terminal that plate 32 is formed is connected with metal cap 4 spot welding through sheet metal 5, first line plate 31 and the second line
The negative pole end that road plate 32 is formed electrically conducts with metal shell 1 through sheet metal 5.During input, use charged electrical
Road, is charged battery core 2；When abnormal, can touch protection circuit, there is not the peaces such as blast in protection battery
Full accident.Also including the damper cylinder 6 being arranged between metal shell 1 and battery core 2, damper cylinder 6 is arranged at gold
Belong between shell 1 and battery core 2, the outside of damper cylinder 6 is provided with damping through hole 61, is relatively arranged on damping
The damping through hole 61 of cylinder 6 both sides is interspersed, and the length direction of damping through hole 61 is perpendicular in damper cylinder 6
Heart axis direction, the distance that the length scale of damper cylinder 6 is matched with metal cap 4 to metal shell 1 bottom is big
Little, damper cylinder 6 can effectively reduce the external world and be transferred to the oscillation intensity of inside battery structure, thus protects battery
Internal structure.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other
Various corresponding changes and deformation, and all these changes and deformation all should belong to this utility model power
Within the protection domain that profit requires.
