Description
Technical field
The utility model design design technical field of lithium ion, more particularly to a kind of lithium with water-proof function from
Sub- accumulator.
Background technology
In recent years, lithium ion battery due to it is higher than energy, have extended cycle life, self discharge is small, safe and reliable, environmentally protective etc.
Many advantages and the deep extensive concern by various circles of society.
Conventional lithium ion battery is generally encapsulated using PVC thermoplastic films, for example, Authorization Notice No. is CN201708215U
Chinese utility model patent disclose a kind of polymer lithium ion power cell group structure, it include three monomer-polymer lithiums
Battery pack is formed together with sticking double faced adhesive tape between ion battery contact surface, and lug is placed equidistant in polymer Li-ion
Power battery pack upper end, and three lugs are symmetrical, then entire polymer lithium ion power cell group is encapsulated with PVC thermoplastic films, even
Plate receiving device is at the top of polymer lithium ion power cell group, and charge and discharge line unit is on connecting plate and lug top.
The Chinese utility model that Authorization Notice No. is CN205960035U for another example discloses a kind of water proofing of lithium battery packaging
Structure comprising battery pack, sealant and middle layer, the sealant are coated on battery pack outside portion, and the sealant is modeling
Glue film configuration, the battery pack are electrically connected with connector, and the connector is electrically connected by connecting line and battery pack, institute
It states connector to be arranged in one side of battery pack, the sealant wraps the junction of connecting line and battery pack, the middle layer
It is wrapped on the outside of sealant.
With the development of shared motor bicycle, higher demand, traditional PVC film pyrocondensation are proposed to the water resistance of lithium battery
Mode, battery both ends easily intake, and gluing is not easy to control, and outer membrane is easily rupturable, and especially power outlet position waterproof is difficult.
Utility model content
The utility model in view of the deficiencies of the prior art, provides a kind of lithium-ions battery with water-proof function.
A kind of lithium-ions battery with water-proof function, includes the accumulator body with power outlet, further includes
The waterproof bag of accumulator body is encapsulated, the waterproof bag is equipped with the pre-embedded pipe that power supply source terminal passes through, the built-in line
Filling with sealant in pipe seals with power outlet and coordinates.
The sack of the waterproof bag has the band that heat-sealing is formed.
The pre-embedded pipe is fixed on by hot pressing at the band.
The waterproof bag is software plastic film material, and the pre-embedded pipe is rigid plastics material.
The thickness of the waterproof bag is 0.1-0.5mm.
Then accumulator body is encapsulated in waterproof bag by the utility model lithium-ions battery by designing a kind of waterproof bag
In play sealing waterproof action, waterproof bag is equipped with the pre-embedded pipe that power supply source terminal passes through, and is filled in pre-embedded pipe
Fluid sealant seals with power outlet and coordinates, so that accumulator body is fully sealed.The utility model lithium-ions battery
Sealing effect is good, can match suitable waterproof bag according to the size of lithium-ions battery, waterproof bag is complete with accumulator
Fitting, is not take up too many size；The waterproof problem at power outlet is effectively solved using pre-embedded pipe mode.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model lithium-ions battery.
Specific implementation mode
As shown in Figure 1, a kind of lithium-ions battery with water-proof function, includes the accumulator with power outlet 2
Ontology 1, further includes the waterproof bag 3 for encapsulating accumulator body 1, and waterproof bag 3 is equipped with the pre-embedded pipe that power supply source terminal 2 passes through
4, it is positive and negative two that power outlet 2, which is divided to, is separately connected the positive and negative electrode of accumulator body 1, correspondingly, pre-embedded pipe 4 is also 2
A, each pre-embedded pipe 4 is passed through for a power outlet 2.Filling with sealant 5 in pre-embedded pipe 4, it is close with power outlet 2
Envelope cooperation, reaches good sealing effect.
The sack of waterproof bag 3 has the band 6 that heat-sealing is formed.Pre-embedded pipe 4 is fixed on by hot pressing at band 6,
Ensure that there is good leakproofness between waterproof bag 3 and pre-embedded pipe 4.
In order to reduce the volume shared by waterproof bag 3 to the greatest extent, waterproof bag 3 is software plastic film material, in this way can be very square
Just so that waterproof bag 3 is bonded completely with accumulator body 1, too many size will not be increased.The thickness of waterproof bag 3 is 0.1-0.5mm.
Transparent PC material may be used in waterproof bag 3, have many advantages, such as waterproof, fire-retardant, wear-resisting, inoxidizability, effective protection accumulator body
1.Pre-embedded pipe 4 is rigid plastics material, ensures that pre-embedded pipe 4 is not crushed damage in use, power supply is caused to draw
Leakproofness at line 2 wrecks, and then influences the leakproofness of entire lithium-ions battery, and waterproof requirement is not achieved.
For the utility model lithium-ions battery in production, prefabricated waterproof bag 3 uses thermoforming process, can be according to not
The size of same accumulator body 1 realizes customization.Prefabricated waterproof bag 3 is initially open state, accumulator body 1 is put into pre-
In the waterproof bag 3 of system, two power outlets 2 are each passed through a pre-embedded pipe 4, are then sealed to the sack of waterproof bag 3, shape
At band 6, pre-embedded pipe 4 is fixed on by hot pressing at band 6, finally the filling with sealant 5 in pre-embedded pipe 4, with electricity
The sealing cooperation of source terminal 2, so that accumulator body 1 is fully sealed.
