Abstract
The invention relates to a gas spring, in particular to an electric gas spring electrically driven. External force needs to be applied by hands to allow the prior gas spring to reciprocate or to be located, and the manual mode causes great inconveniences to users. The electric gas spring is characterized in that a drive motor, a decelerator and a coupling are mounted in a motor connecting sleeve of an electric drive device; a spiral reciprocating mechanism, a guide sleeve and a piston rod component are disposed in a gas spring cylinder barrel; the gas spring cylinder barrel is filled with nitrogen. The electric gas spring has the advantages that applying external force by hands is avoided, more convenient, safer and high-comfort humanized services are provided for users, and the application range of the gas spring is widened; the electric gas spring is compact in structure, simple to mount, convenient to use, stable in performance, safe and reliable, and widely applicable.
Description
Technical field
The present invention relates to a kind of air spring, particularly relate to the power-actuated electronic air spring of a kind of employing.
Background technique
Air spring is a kind ofly can play support, buffering, braking, highly regulate and the industrial accessory of the function such as angle adjustment.This product has application widely in fields such as automobile, aviation, machine-building, medical apparatus, furniture, buildings, it mainly is comprised of cylinder barrel, piston rod, piston, Sealing and joint outer part.The to-and-fro motion of air spring or location must artificially apply external force with hand, and this mode is brought much inconvenience to the user, particularly use when volume is greatly or on the heavier device of weight when air spring, and human body and article are easily damaged, and affect its Security; And this mode that artificially applies external force with hand, also be confined to the height of human body and the size of this body forces of user (men and women), and the user must stay scene, if rained or this defect of bad weather can be more obvious; Simultaneously, also make the application of air spring be subject to certain narrow limitation, as for surpassing certain altitude or being subjected to the restriction of surrounding environment, in the place that human body is difficult for touching, air spring just can't be used, and the advantage of air spring is not in full use.
Along with the raising day by day of people's living standard, the continuous renewal of consumption idea, what the user more focused on is simple and convenient, safety and comfort.Therefore, electronic air spring replaces common air spring will become a kind of trend, is also the lifting update product of air spring.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly to the user, brings great convenience, have more Security and travelling comfort than original air spring, more can enlarge the application area of air spring, and can directly substitute the electronic air spring of common air spring.
Above-mentioned technical problem of the present invention is to solve by the electronic air spring that a kind of following structure is provided, this electronic air spring is comprised of the gentle spring of electric driver, and described electric driver is by the motor connecting sleeve and be positioned at drive motor, retarder and the coupling that the motor connecting sleeve connects successively and form; Described air spring is comprised of cylinder barrel and the spiral reciprocator, pilot sleeve and the piston rod part that are positioned at cylinder barrel; One end of described spiral reciprocator is connected on drive motor by the retarder of coupling and electric driver, the other end is connected with the piston rod in the air spring piston rod unit, and be arranged in the pilot sleeve of air spring, described pilot sleeve is fixed in the air spring cylinder barrel, the motor connecting sleeve of electric driver with the air spring cylinder barrel for being fixedly connected with.
Spiral reciprocator consists of screw mandrel, feed screw nut and axial anti-block parts in above-mentioned technological scheme, and described axial anti-block parts can prevent that screw mandrel from producing jam when pressurized gas produce larger end thrust;
Described feed screw nut is provided with tongue outward, in described pilot sleeve, be provided with direction recess, feed screw nut and pilot sleeve in described spiral reciprocator cooperatively interact, and can prevent that the feed screw nut from rotating with screw mandrel, and guarantee that piston rod is with feed screw nut's moving linearly in pilot sleeve;
Described piston rod is designed to hollow stem, can shorten base long, makes structure compacter;
Motor connecting sleeve outboard end and air spring piston rod end at electric driver are fixed with respectively the bulb connected element, can conveniently install.
Compared with prior art, because the present invention has set up electric driver, spiral reciprocator and pilot sleeve in the air spring cylinder barrel, have been set up, rotatablely moving of drive motor can form by spiral reciprocator the linear reciprocating motion of air spring piston bar, feed screw nut in spiral reciprocator cooperatively interacts with the pilot sleeve be fixed in cylinder barrel, can prevent that the feed screw nut from rotating with screw mandrel, and guarantee that piston rod is with feed screw nut's moving linearly in pilot sleeve.The to-and-fro motion of air spring or location are completed by electric drive, have substituted artificially and have applied external force with hand, provide more convenient to the user, have more the human nature service of Security and travelling comfort, and have enlarged the application area of air spring.Compact structure of the present invention, simple, easy to use, the stable performance, safe and reliable of installation, application area is extremely extensive, has vast potential for future development.
The accompanying drawing explanation
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Wherein: 1, ball stud connected element 2, motor connecting sleeve 3, drive motor 4, retarder 5, cylinder barrel 6, screw mandrel 7, feed screw nut 8, piston rod part 9, piston rod 10, pilot sleeve 11, spiral reciprocator 12, axial anti-block parts 13, coupling
Embodiment
As shown in the figure, the drive motor 3 of electric driver, retarder 4 and coupling 13 are connected and are fixed in motor connecting sleeve 2 by roll extrusion electronic air spring of the present invention successively; Air spring cylinder barrel 5, and in described cylinder barrel 5, by screw mandrel 6, feed screw nut 7 and the axial spiral reciprocator 11 that forms of anti-block parts 12, it is equipped with an end of axial anti-block parts 12, retarder 4 by coupling 13 and electric driver is connected on drive motor 3, and its cover has an end of feed screw nut 7 to be connected with the piston rod 9 in air spring piston rod unit 8; Described spiral reciprocator 11 is arranged in the pilot sleeve 10 of air spring, feed screw nut 7 in described spiral reciprocator 11 cooperatively interacts with the pilot sleeve 10 of air spring, described pilot sleeve 10 is fixed in the air spring cylinder barrel 5, and the gentle spring cylinder barrel 5 of the motor connecting sleeve 2 of described electric driver connects also to be fixed by roll extrusion.It is airtight that described cylinder barrel 5 and motor connecting sleeve 2 two ends are respectively charged into blocking device, in the air spring cylinder barrel, is filled with the nitrogen of corresponding pressure P.Motor connecting sleeve 2 outboard ends and air spring piston bar 9 ends of described electric driver are fixed with respectively bulb connected element 1, and the link of any one Connecting format can be installed, and the same with common air spring simple and convenient.
