Abstract
The utility model relates to a lithium cell group is refered in particular to in the lithium cell field. Be equipped with the circuit board between lithium cell group's positive electrode binding post, the negative electrode binding post, integrated miniature transformer, usb interface and temperature sensor on the circuit board, lithium cell group are divided into first battery set with the second group battery and be connected with the control module of circuit board is electric respectively. The inside of shell is provided with the anticollision layer, and the spring has been arranged to crashproof in situ. Inside pressure sensor and the relief valve of being equipped with of shell. In order to prevent that the usb interface from being drenched by water or to be touched by human mistake, have insulating waterproof cover on the usb interface. When the battery reached to set the temperature, changeable extremely another group's battery was supplied power, consequently can not receive the restriction of temperature to more group batteries are gone into, its use power can be improved in the time of life -span of extension group battery, setting up the usb interface simultaneously and providing service function much more more for the user, anticollision layer and relief valve be its security performance further then.
Description
Technical field
The utility model relates to field of lithium, refers in particular to a kind of lithium battery group.
Background technology
Lithium ion battery energy density is high, has extended cycle life, and is widely used in digital product, electric tool, electric bicycle, new-energy automobile and energy storage etc., is acknowledged as the novel battery of most potentiality.But lithium ion battery remains at some problems at large scale manufacture view at present, require high to special package, overheated use can affect battery life, even causes security incident.When lithium battery group is arranged in electric motor car, it cannot provide more using function for user.
Summary of the invention
The purpose of this utility model is for the existing state of the art, provides a kind of lithium battery group of changeable use.
For achieving the above object, the utility model adopts following technical scheme:
A kind of lithium battery group, mainly comprises shell 1, upper cover 5, lithium battery group; Circuit board 2 is provided with between the positive electrode binding post 21 of lithium battery group, negative electrode binding post 22, integration of compact transformer 22, usb interface 21 and temperature sensor 23 on circuit board 2, lithium battery component is that the first battery pack 71 and the second battery pack 72 are also electrically connected with the control module of circuit board 2 respectively.
Further, the inside of described shell 1 is provided with crashproof layer 8, is furnished with spring 10 in crashproof layer 8.
Further, pressure sensor 9 and relief valve 6 are equipped with in described shell 1 inside.
Further, be integrated with display module in described circuit board 2, and be electrically connected with display screen 12.
Further, described upper cover 5 is provided with photoscope.
To be drenched by water to prevent usb interface or by human body false touch, with insulative water-proof cover on described usb interface 21.
the beneficial effects of the utility model are:
When battery reaches the temperature of setting, can switch to another Battery pack and power, therefore by the restriction of temperature, more battery pack can not be incorporated to, can be improved it while extending the life-span of battery pack and use power; Arrange usb interface for user provides more using function simultaneously, crashproof layer and relief valve then its security performance further.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model partial structurtes schematic diagrames.
embodiment:
Can have the object of the utility model, feature and function to make juror and further understand, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
Referring to shown in Fig. 1, is the structural representation of the preferred embodiment of the utility model,
A kind of lithium battery group, mainly comprises shell 1, upper cover 5, lithium battery group, the positive electrode binding post 21 of lithium battery group, circuit board 2 is provided with between negative electrode binding post 22, integration of compact transformer 22 on circuit board 2, usb interface 21 and temperature sensor 23, lithium battery component is that the first battery pack 71 and the second battery pack 72 are also electrically connected with the control module of circuit board respectively, pressure sensor 9 and relief valve 6 are also equipped with in shell 1 inside, battery pack in use can persistent fever, especially when high load capacity, battery-heating especially easy initiating failure even causes damage, and general cooling measure cannot this problem of fully effective solution.The utility model passes through at the other set temperature transducer 23 of battery pack, when the first battery pack 71 temperature reaches preset temperature by information feed back to the control module of circuit board, power supply source is switched to the second battery pack 72, first battery pack 71 quits work and realizes cooling, and then improve the heat resistance of battery pack, reduce over the infringement that the torrid zone is come, if certainly need not also can be closed by this handoff functionality.When pressure stacks raises, by relief valve 6 step-down in order to avoid battery generation bulging is even exploded.Integrated miniature transformer 22 in circuit provides separately small voltage to power for usb interface 21.
As preferred technical scheme, the inside of described shell 1 is provided with crashproof layer 8, is furnished with spring 10 in crashproof layer 8, and when shell 1 is subject to external force collision, spring 10 Absorbable rod in crashproof layer or reduce external power, ensures the stability of battery.Be integrated with display module in described circuit board 2, and be electrically connected with display screen 12, the various data of battery such as temperature, pressure etc. can be fed back by display screen 12.It is in order to user is convenient to check the internal state of battery that upper cover 5 is provided with photoscope.To be drenched by water to prevent usb interface or by human body false touch, described usb interface 21 is buckled with insulative water-proof cover, and it is made up of rubber.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, what describe in above-described embodiment and specification just illustrates principle of the present utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
