Description
Technical field
This utility model relates to a kind of drag device, particularly a kind of automobile power back door drag device.
Background technology
In the modern life, automobile is the vehicles that people are important, and the boot of automobile, it is for depositing in automobile
The part of article.Tail-gate in the most boot of current automobile, uses mechanical locking device, structure letter
Single, with low cost；But it is bad many times to there is locking, cause the situation of object loss.So the tail of a lot of superior automobile
Door, all uses electricity desorption system.In electricity desorption system, most important parts are the push rod control of tail-gate, current automobile power back door
The kind of drive, is that planet tooth reducing motor is directly connected with bull screw mandrel, and compression spring plays assosting effect, and stand-by motor drives
Tail-gate is opened；But spring is owing to being chronically at most compressed state, spring decay is serious, causes tail-gate support force after opening not
Foot, the situation that tail-gate falls down.Therefore it is accomplished by increasing the block structure, neither affects motor-driven, can open at tail-gate again
After, increase support force so that tail-gate will not fall down.Although Some vehicles is mounted with antivibrator, but effect is bad and has logical
Poor by property, can only customize for vehicle；Volume is big, structure is complicated, cost is high；System operation complexity, in-convenience in use etc..
Utility model content
In order to solve the problems referred to above, the purpose of this utility model is for providing a kind of compact conformation, compact, versatility
By force, flexible operation, a kind of automobile power back door drag device that cost is lower.
The purpose of this utility model is achieved in that a kind of automobile power back door drag device, including outer sleeve, increases resistance part
Part, motor contact and screw connecting piece, resistance-enhancing component is arranged in outer sleeve, motor contact, screw connecting piece position respectively
In the two ends of outer sleeve, described resistance-enhancing component includes increasing resistance spring, little spring and little spring overcoat, wherein, motor contact
Being connected to outside little spring put, two terminations of little spring are connected on motor contact；Little spring is enclosed within screw connecting piece；
Little spring overcoat is arranged in increasing resistance spring, and two terminations increasing resistance spring are connected in the groove of little spring overcoat.
Described motor contact is fixedly connected on the outfan of planet tooth reducing motor by connecting rod.
Described screw connecting piece is fixedly connected on bull screw mandrel by connecting rod.
After using technique scheme, this utility model has compact conformation, compact, highly versatile, operation spirit
The advantage such as live, cost is lower, be widely portable in the control system of various automobile tail gate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is described further.
Fig. 1 is of the present utility model to disassemble out rear structural representation；
Fig. 2 is that this utility model cuts rear structural representation open along axis；
Detailed description of the invention
The utility model is described in more detail below in conjunction with the accompanying drawings:
A kind of automobile power back door drag device, including outer sleeve 1, resistance-enhancing component 2, motor contact 3 and screw connecting piece
4, resistance-enhancing component 2 is arranged in outer sleeve 1, and motor contact 3, screw connecting piece 4 lay respectively at the two ends of outer sleeve 1, described
Resistance-enhancing component 2 include increasing resistance spring 21, little spring 23 and little spring overcoat 22, wherein, motor contact 3 is connected to little spring
On overcoat 22, two terminations of little spring 23 are connected on motor contact 3；Little spring 23 is enclosed within screw connecting piece 4；Little bullet
Spring overcoat 22 is arranged in increasing resistance spring 21, and two terminations increasing resistance spring 21 are connected in the groove of little spring overcoat 22.
Described motor contact 3 is fixedly connected on the outfan of planet tooth reducing motor by connecting rod.
Described screw connecting piece 4 is fixedly connected on bull screw mandrel by connecting rod.
Operation principle of the present utility model is:
A kind of automobile power back door drag device is installed between planet tooth reducing motor and bull screw mandrel, and described motor is even
Fitting is fixedly connected on the outfan of planet tooth reducing motor by connecting rod, and described screw connecting piece is solid by connecting rod
Surely bull screw mandrel it is connected to.Increasing resistance spring to be installed on outer sleeve, little spring is installed on outside little spring and puts, under normal condition,
Little spring and little spring overcoat are interference fit, and increasing resistance spring is interference fit with outer sleeve.Motor contact is installed on
Little spring puts outward, and two of little spring is fixed and on motor contact.When motor contact is driving link rotation, little spring
External diameter shrinks, and little spring and little spring overcoat become matched in clearance, and little spring rotates along with motor contact；Screw connecting piece is pacified
It is loaded between little spring two, moves when motor contact drives little spring to rotate, the most also drive screw connecting piece to rotate.Work as silk
When joint element for bar is driving link rotation, little spring external diameter swell, little spring coordinates tighter with little spring overcoat, and frictional force is bigger,
Thus little spring drives little spring overcoat to rotate along with screw connecting piece.Little spring overcoat is installed in increasing resistance spring, increases resistance bullet
The two ends of spring are positioned in little spring overcoat groove, when little spring overcoat rotates, increasing resistance spring can be driven to rotate together, increase resistance bullet
Spring produces friction with outer sleeve, thus increases resistance.Little spring overcoat loads outer sleeve, and the groove of little spring overcoat blocks increasing resistance
The two ends of spring.Motor contact loads little spring overcoat, and motor contact is blocked at two of little spring.Screw connecting piece is installed
Middle position in little spring two.When motor contact rotates as driving link, drive little spring external diameter shrink, little spring with
Little spring overcoat becomes interference fits, and little spring rotates along with motor contact, and motor contact drives screw connecting piece simultaneously
Rotate；When screw connecting piece rotates as driving link, driving little spring external diameter swell, little spring coordinates more with little spring overcoat
Tightly, frictional force is bigger, thus little spring drives little spring overcoat to rotate along with screw connecting piece, and little spring overcoat drives and increases resistance bullet
Spring rotates together, and increasing resistance spring is interference fit with outer sleeve, and resistance is big, thus produces a reactive torque, increases screw mandrel and turns
Dynamic resistance, screw connecting piece drive motor connector rotates simultaneously；This structure, on the premise of not affecting motor-driven, increases
The strut support force of Men Kaihou.
Certainly, embodiment described above, preferred embodiment the most of the present utility model, not limit this practicality
Novel practical range, therefore all equivalences done according to structure, feature and the principle described in this utility model claim
Change or modification, in the range of being all included in this utility model.
