The installation of the explosion-proof valve of current design is carried out the transition through a metal connecting plate, and the concrete structure is shown in figure 3: the explosion-proof valve is arranged in the valve hole 6 of the metal connecting plate 4, and the metal connecting plate 4 is arranged on the battery box body 1. The connected mode of metal connecting plate 4 and battery case body 1 is realized jointly through sealed glue 9 and sealing bolt 7 cooperation, at first beat sealed glue 9 on metal connecting plate 4, treat to glue solidification behind a period, the rethread nut 8 fastens, the metal sheet is connected and is beaten glue, the solidification, because the curing time who glues is long, cause the production beat length, and the bolt also adopts sealing bolt 7, it is strict to battery case body trompil's position degree and aperture requirement, if the deviation is too big, glue on the sealing bolt 7 does not play the complete sealing effect. When actually inflating, the air leakage phenomenon easily appears at the position of the sealing bolt, the maintenance cost is increased, the waste of the productivity is caused, and the production efficiency is low.
As shown in fig. 3 and 4, when the airtightness is verified, after the inner side is inflated, the bolt position is easily poor in sealing and air leakage, the bolt position needs to be sealed and repaired again, and then the airtightness is detected, so that the labor hour is wasted, the maintenance cost of parts is increased, and the waste of productivity is caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome prior art and adopt sealed gluey use of combining sealing bolt to realize sealed to the battery case, the production beat is long, and sealing bolt position detects in airtight that air leakage appears very easily, causes the repair and the repeated detection of spare part, and extravagant productivity is not enough, the utility model provides an adopt sealed pad, metal connecting plate and projection welding double-screw bolt integrated mode to realize sealed to the battery case, the production beat is fast, and is efficient, sealed effect stable automobile battery case explosion-proof valve metal connecting plate's installation, seal structure.
The technical scheme is as follows:
the utility model provides a cooperation connection structure of car battery case explosion-proof valve metal connecting plate and battery box body, includes battery box body, metal connecting plate, explosion-proof valve installs on metal connecting plate, the structure adopt sealed pad, metal connecting plate and the integrated mode of projection welding double-screw bolt sealed to the battery case installation, metal connecting plate's outer circumference on bond and to have sealed the pad, the inboard metal connecting plate's of sealed pad welding has the projection welding double-screw bolt on the surface, the metal sheet passes through the projection welding double-screw bolt and fastens with the battery box body with tightening bolt, seals through sealed pad and battery box body.
As a preferable scheme:
the sealing gasket is directly bonded on the outer circumference of the metal connecting plate in a gum mode.
The number of the projection welding studs is set to be a plurality according to the size of the plate surface of the metal plate.
The plurality of projection welding studs are arranged along the circumferential direction of the metal plate at equal intervals.
Compared with the prior art, the utility model discloses a sealed integrated mode of pad, metal connecting plate and projection welding double-screw bolt realizes the metal connecting plate assembly supply of material. The remarkable effects are as follows:
the sealing mode of the metal connecting plate and the battery box body is as follows: the sealing gasket is directly bonded on the metal connecting plate in a gum mode, so that the sealing effect is guaranteed, the sealing effect is stable, and the curing time is not needed.
On the mounting means of metal connecting plate and battery box body: projection welding double-screw bolt lug weld is on metal connecting plate, and metal connecting plate need not carry out the trompil, and directly with tighten the bolt tighten can, compare prior art's sealed bolt fixed mode, there is not the risk of leaking gas, the structure is more stable, staff convenient operation moreover, production efficiency is high.
Because the utility model discloses a sealed integrated mode of pad, metal connecting plate and projection welding double-screw bolt has realized the modularization supply of material, reduces the waste of resource.
