Abstract
The invention discloses a thermal-sealing structure of a valve-controlled lead-acid storage battery shell. An upper thermal-sealing tenon and a lower thermal-sealing tenon are respectively arranged on the joint of an upper battery cover and a battery cylinder, thermally sealed together and respectively provided with waved cross sections, wherein crests and troughs in correspondence are attached by sides and thermally sealed together, the two thermal-sealing tenons have the cross section thickness of 1.5-3mm and the tenon height of not smaller than 5mm, the crest height is 2-4 times the thickness of the cross section, and the crest distance is 2-3 times the crest height. Because the thermal-sealing tenons have the waved cross sections, and the thickness of the cross sections, the heights and the wave sizes of the thermal-sealing tenons are controlled, the thermal-sealing structure can buffer the impact deformation and the thermal-sealing stress deformation of the battery shell, and can effectively prevent the sealing surface stress tearing of the battery shell, particularly a valve-controlled lead-acid battery ABS (Acrylonitrile Butadiene Styrene) shell so as to achieve the aim of preventing the thermal-sealing leakage of the battery.
Description
Technical field
The present invention relates to a kind of lead acid accumulator housing, especially valve-regulated lead-acid battery housing heat-sealing structure.
Background technology
Lead acid accumulator relies on its good ratio of performance to price, higher operating voltage, heavy-current discharge performance and high low temperature performance preferably, both being suitable for floating charge uses, the advantage that is suitable for again starting, recycling is occupied critical role in the secondary cell field, be widely used in fields such as stand-by power supply, energy conservation, power source.
The valve-regulated lead-acid battery production technology is quite ripe now, particularly the employing of ABS plastic housing heat-sealing technology makes the production efficiency of battery greatly improve, and production environment is greatly improved, production cost descends a lot, and the involution quality of small-capacity cells housing is very reliable.But for the high capacity cell more than the 1000Ah because battery is very heavy, move, impact suffered in the installation process is bigger, tears for preventing ABS plastic housing heat-sealing section, plastic casing heat-sealing tenon all designs very widely, to bear bigger shearing force.Because the heat-sealing limit is very wide, the thermal stress that produces during heat-sealing is very big, particularly the flame-proof ABS plastic casing sometimes behind the heat sealing soon, interior thermal stress promptly causes cracked housing and transaxle, causes the battery effusion then.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the existing lead acid accumulator housing heat-sealing back defective of cracking seepage easily, and a kind of high capacity cell that is used for is provided, and can avoid the valve-regulated lead-acid battery housing heat-sealing structure of battery container heat-sealing seepage.
Technical scheme of the present invention is: the joint portion of cell cover and battery barrel is provided with heat-sealing tenon and following heat-sealing tenon respectively in this structure, two heat-sealing tenon heat sealings are integral, its improvements are described section wavinesses that go up heat-sealing tenon and following heat-sealing tenon, upper and lower heat-sealing tenon crest, trough are corresponding, two heat-sealing tenon sides are adjacent to, heat-sealing is integral, two heat-sealing tenon section thicknesses, 1.5～3mm, and two heat-sealing tenon height are not less than 5mm.
Further scheme is: describedly go up the heat-sealing tenon and following heat-sealing tenon height is 5～8mm, two heat-sealing tenon crest heights are for sealing 2～4 times of tenon section thickness, and corrugation pitch is 2～3 times of crest height.
The present invention is owing to controlled the section width of housing heat-sealing tenon, and the thermal stress that produces when making the housing heat-sealing reduces; Section Design waviness that will the heat-sealing tenon, the height and the waveform size of control housing heat-sealing tenon, the blastic deformation that not only can buffer battery foreign impacts power causes, and the stress deformation that can the bumper housing heat-sealing produces.Therefore, this heat-sealing structure can effectively prevent battery container, and particularly valve-regulated lead-acid battery ABS plastic housing sealing surface stress is torn, thereby reaches the purpose that prevents battery heat-sealing seepage.
Description of drawings
Accompanying drawing is upper and lower heat-sealing tenon heat-sealing pre-structure schematic diagram among the present invention.
Embodiment
Referring to accompanying drawing, cell cover 1 and battery barrel 4 are all ABS plastic spare, around the back of loam cake 1 and the port of cylindrical shell 4 be respectively equipped with and seal tenon 2 and following heat-sealing tenon 3, upper and lower heat-sealing tenon section waviness, the thick 2mm of section, the high 6mm of two heat-sealing tenons, crest height of wave 6mm, corrugation pitch 12mm, upper and lower heat-sealing tenon crest, trough are corresponding, and its side is adjacent to heat-sealing and is integral during assembling.
