Equipped with the screw rod transmission axis that damping spring and the small lower section of upper section are big between shell and the lower case.
In above-mentioned technical proposal, more specific technical solution is: the damping fin include upper damping fin, middle damping fin and under
Damping fin, wherein the upper damping fin is located at below the upper compartment；The driver blade includes upper driver blade and underdrive piece, institute
It states driver blade to be located between the upper damping fin and the middle damping fin, the underdrive piece is located at the middle damping fin and institute
It states between lower damping fin.
Further: the upper section of the screw rod transmission axis from bottom to top passes through the lower damping fin, underdrive piece, middle damping
Piece, upper driver blade and upper damping fin, and the lower section of the screw rod transmission axis is fastened below the lower damping fin；The damping
Spring is set in the lower section of the screw rod transmission axis and top is connected with the lower damping fin, bottom end and the positioning ring phase
Even.
Further: the lower section of the reduction gearbox connector passes through the positioning ring, and the reduction gearbox connector
Upper section be fastened on the positioning compartment, the upper section of the reduction gearbox connector is connected with the screw rod transmission axis, described slow
Punching pad is located between the reduction gearbox connector and the screw rod transmission axis.
Further: the cushion is rubber parts.
Further: the upper housing and the lower case are tubing string shape.
Further: the damping fin and the driver blade are annular shape, and the annular diameters of the damping fin are greater than institute
State the annular diameters of driver blade.
Further: the upper housing is to be threadedly coupled with the lower case.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:
1, two panels driver blade is clamped by using three pieces damping fin and damping spring plays the role of increasing resistance, then by using rubber system
At cushion play effectiveness in vibration suppression, the two be allowed to be adapted by continuously improving in structure be combined together, realize
Resistance can be increased and the effect of energy vibration damping；
It 2, is in order to by driver blade and screw rod by the way that the annular diameters of damping fin are designed to the annular diameters greater than driver blade
Transmission shaft is in clearance fit, to reach in the case where the two is not interfere with each other while rotate；
3, the present invention has compact-sized, compact, versatile, flexible operation, modularization, support effect more preferable etc. excellent
Point is widely portable in various motorcar electric tailgate struts.
Detailed description of the invention
Fig. 1 is fractionation schematic diagram of the invention.
Fig. 2 is structure sectional view of the invention.
Specific embodiment
The invention will be further described for example with reference to the accompanying drawing:
Damper as depicted in figs. 1 and 2 is equipped with down including being equipped with inside the upper housing 1 and lower end of upper compartment 1-1 inside upper end
The lower case 9 of compartment 9-1 is equipped with the damping fin 2 and driver blade 3 for being fastened on compartment 1-1 inside upper housing 1；Inside lower case 9
