Abstract
The utility model discloses an upper cover of a nickel-hydrogen battery, which relates to a shell structure of the nickel-hydrogen battery. The improvement of the upper cover is as follows: the middle part is provided with a liquid injecting hole; a ring-shaped pillar is arranged in the liquid injecting hole; a through hole inside the ring-shaped pillar is provided with a multi-hole filtering sheet; the top of the ring-shaped pillar is provided with a rubber sleeve cap; the upper port of the liquid injecting hole is provided with a covering sheet with exhaust holes. The upper cover is used for encapsulating of the nickel-hydrogen battery; the electrolyte is injected through the liquid injecting hole; gas with a certain pressure inside the battery can be smoothly exhausted, so as to effectively block leakage; the safety and the reliability are good; the structure is compact; the volume is small; therefore, the installing and the assembling of the nickel-hydrogen battery are convenient, meanwhile, the manufacturing process of the battery is simplified, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of shell structure of Ni-MH battery, particularly the Ni-MH battery loam cake.
Background technology
Ni-MH battery (NiMH) replaces cadmium (Cd) by nickel-cadmium cell (NiCd) improvement with the metal that can absorb hydrogen.It provides the capacitance higher than nickel-cadmium cell with identical price, does not have memory effect substantially, is a kind of battery of environmental protection.Advantages such as Ni-MH battery has the energy density height, the speed that discharges and recharges is fast, in light weight, life-span length, non-environmental-pollution have become the new forms of energy product that countries in the world are competitively developed and developed.Since the nineties in last century, successively enter the industrialization stage at home and abroad, and be mainly used in consumer electronics field, and in the majority with A type, AA type, be used for notebook computer, video camera, pocket telephone etc. mostly.
In recent years because primary energy anxieties such as oil, and progressively being rooted in the hearts of the people of environmental protection concept, the large-capacity power type Ni-MH battery also more and more is subject to people's attention, power nickel-hydrogen cell can also be widely used in beeliner, electric locomotive, large-scale military, civilian naval vessel and movable electric tool and building, machine room and the back-up source facilities of communicating by letter etc. such as small-sized electric pleasure-boat, electric saw, hay mover simultaneously except that can being used for electric bicycle, motorcycle, hybrid vehicle.
Ni-MH battery is after long-term the use, its electrolyte inside can be decomposed and emitted gas, make internal pressure increase, at present big capacity Ni-MH battery adopts the method that installs safety valve on cell cover additional to solve more, and safety valve is opened and discharged gas in the shell when inside reaches certain pressure.Take out of together but have alkaline electrolyte in the gas of discharging tends to battery under situations such as overcharging, tilt, keep flat, cause corrosion and damage the outer battery link of housing, electronic devices and components.Simultaneously the volume of safety valve is generally bigger, and gives prominence in outside, and the connection of whole Battery pack is made troubles with installing and fixing.
Summary of the invention
The objective of the invention is bigger than normal at the existing existing safety valve easy-to-leak liquid of big capacity Ni-MH battery, volume, be not easy to the fixing shortcoming of whole group connection, a kind of simple and compact for structure, easy-to-leak liquid, safe and reliable, whole Battery pack connection Ni-MH battery loam cake easily not is provided.
Technical scheme of the present invention is: the Ni-MH battery loam cake is made by polypropylene, ABS or other high-quality engineering plastics, respectively there is a terminal delivery outlet at two ends, its improvements are that the middle part of loam cake is provided with liquid injection hole, hollow important actor is arranged in the liquid injection hole, in the through hole of hollow important actor inside the porous filtering sheet is housed, the rubber cap bag that is positioned at porous filtering sheet top is equipped with at hollow important actor top, and the upper port of liquid injection hole is provided with cover plate, and steam vent is arranged on the cover plate.
Further scheme is: described porous filtering sheet is polypropylene or polytetrafluoroethylene member, and porosity is 60%～80%; Described cover plate upper air-vent aperture is 0.05～1mm; Gap between described rubber cap bag and the cover plate is 0.1～5mm; The upper port of described terminal delivery outlet is provided with annular groove.
Be provided with liquid injection hole in the middle of this Ni-MH battery loam cake, after cell package, can inject electrolyte to inside battery by this liquid injection hole.Change into and daily use in after a small amount of gas of producing of inside battery reaches certain pressure, gas extruding rubber cap bag make its with hollow important actor between produce slit discharge internal gas.Internal gas can freely pass through the porous filtering sheet, but electrolyte is when running into the porous filtering sheet of material such as polytetrafluoroethylene, because the effect of surface tension of liquid and being intercepted can not revealed through liquid injection hole.
Cover plate is provided with one or more steam vents, will discharge outside batteries through the gas that the rubber cap bag is discharged by steam vent, and its aperture prevents that than I the small quantity of water droplets of outside batteries from entering.
This Ni-MH battery loam cake has the function of safety valve simultaneously, can discharge internal gas smoothly, can effectively prevent the phenomenon of leakage, and is safe and reliable.This loam cake is located at porous filtering sheet and rubber cap bag in the liquid injection hole, and compact conformation makes Ni-MH battery that combined and instant is installed, and cell making process simplification, cost are reduced.
Description of drawings
Accompanying drawing is a Ni-MH battery loam cake cross-sectional view.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
Concrete implementation step of the present invention is: at first adopt usual manner to manufacture Ni-MH battery cluster and housing, and cluster is put into housing.Adopt polypropylene or ABS raw material to make this Ni-MH battery loam cake 9, be provided with liquid injection hole 3, in liquid injection hole, be provided with hollow important actor 8 in the centre of loam cake with injection moulding or machining process.There is terminal delivery outlet 6 at the loam cake two ends, and its upper port is provided with annular groove 1.
Adopting heat-sealing or glue encapsulation method is whole with this Ni-MH battery loam cake and Ni-MH battery case bonding.On the annular groove 1 on terminal delivery outlet 6 tops, lay O type rubber ring or add and be coated with adhesive, use the fastening terminal of nut subsequently.After cell package, inject electrolyte to inside battery by liquid injection hole 3.
Then lay porous filtering sheet 5 in the through hole of liquid injection hole hollow core important actor 8, and load onto rubber cap bag 2 at the top of hollow important actor 8, the porous filtering sheet is polypropylene or polytetrafluoroethylene material, and porosity is 65%.Add a cover cover plate 4 in liquid injection hole 3 upper port at last, cover plate is provided with four steam vents 7, and the diameter of steam vent is 0.08mm.The interval that 2mm is arranged between cover plate 4 and the rubber cap bag 2.
Can change into according to a conventional method, test this battery subsequently, the gas that changes into, produces in test and the use can be discharged no bulging phenomenon of leakage generation smoothly by porous filtering sheet 5 and rubber cap bag 2.This Ni-MH battery need not to install additional in addition safety valve, and the battery volume reduces, and compact conformation is installed combined and instant.
