Cylinder body middle part and connection silencer；The piston/cylinder two ends are connected by gas piping, and the bleeding point is located at gas piping
Interlude.This application drives two piston cylinder workings being symmetrical set by an eccentric drive shaft simultaneously, improves and fills
Gas efficiency.But use an eccentric drive shaft to drive two piston rods simultaneously so that vibration and noise during inflation pump work
It is bigger, therefore have to reduce noise using silencer；But serious vibration influences whether the service life of inflator pump, together
When its structure it is also more complicated.
The content of the invention
The technical problems to be solved by the invention be for prior art present situation provide one kind can effectively reduce vibration and
Noise is so as to the automobile inflator pump increased the service life.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：The automobile inflator pump, including for driving work
Drive device, the first cylinder and the second cylinder of stopper rod motion and the gas outlet phase with first cylinder and the second cylinder
The gas tube of connection, it is characterised in that the output end drive connection connecting seat of the drive device, the connecting seat, which is rotated, to be set
In the housing of the automobile inflator pump, the piston rod of the first cylinder is connected on the connecting seat by the first connection eccentric shaft,
The piston rod of second cylinder is connected on the connecting seat by the second connection eccentric shaft, first connecting shaft and described
Second connecting shaft is arranged on the connecting seat relative to the Central Symmetry of the connecting seat.
Preferably, the connecting seat can include pedestal, and the both ends of the pedestal are rotatably arranged on clutch shaft bearing respectively
In second bearing, the middle part of pedestal described in the output end drive connection of the drive device.
Connection gear is fixedly connected with the middle part of the pedestal；The drive device includes motor and driving gear set, institute
State the input gear of driving gear set described in the output shaft drive connection of motor, the output gear of the driving gear set with it is described
Connection gear is meshed.The program is simple in construction, stable transmission.
As an improvement, can also be connected with pressure switch on the gas tube, the push rod connection of the pressure switch is described
The switch of drive device.
Compared with prior art, connecting seat and two cylinders and connecting seat in automobile inflator pump provided by the present invention
Attachment structure, can offset the vibration of connecting seat, reduce the service life of noise, effectively extension inflator pump；And simple in construction,
Compact, action transmission is reliable and stable.
Brief description of the drawings
Fig. 1 is schematic diagram of the embodiment of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, the automobile inflator pump includes being provided with housing (not shown) housing：
