As shown in figures 1-4, the embodiments of the present invention are conveniently adjusted the electric and hand roller shutter type goods of the pre- torsion of torsional spring
Vehicle car door, including guide rail 1, supporting plate 2, spool 3, reel 4, roller shutter 5, driving device 6, chain-drive mechanism 7, limiter 8, control
Button 9, controller 10 and torsional spring 11 processed；The guide rail 1 is divided into 12 rear side both sides of compartment cabinet, and supporting plate 2 is fixedly arranged on guide rail 1
12 both sides of compartment cabinet of top, spool 3 is located between supporting plate 2 to be rotatablely connected with supporting plate 2, and 4 sets of reel outside spool 3
Face is coaxially arranged and is fixedly connected；The roller shutter 5 is hinged by the curtain sheet 13 of multiple strips and is connected in series, the roller shutter
5 are wrapped on reel 4 and can slide up and down along guide rail 1；The driving device 6 includes motor 14, gearbox 15 and brake apparatus
16, the motor 14 and controller 10 are electrically connected and are controlled by it, the output shaft of the input terminal connection motor 14 of gearbox 15, system
Dynamic device 16 connects the spool of motor 14 and is electrically connected with controller 10；The limiter 8 is for controlling 5 raising and lowering of roller shutter
Be automatically stopped position, the limiter 8 and gearbox 15 transmission connection and controller 10 be electrically connected；The control button 9 and control
Device 10 processed is electrically connected, and the working condition of motor 14 is controlled by controller 10；
The spool 3 is hollow structure, and one end is equipped with one and connects from the outside to the core through supporting plate 2 and with 2 screw thread of supporting plate
The bolt 17 connect, 17 head of bolt put in the hollow interior of spool 3；The torsional spring 11 is set in spool 3,11 one end of torsional spring
It is fixedly connected with 3 inner wall of spool, the other end is fixedly connected with the head of bolt 17；Described 3 one end of spool is arranged with one and its turn
The driven sprocket 18 of dynamic connection, the driven sprocket 18 connect 4 end of reel, the electricity by an energization mating type electromagnetic clutch 19
Magnet clutch 19 and controller 10 are electrically connected；The output shaft of the gearbox 15 connects driven sprocket 18 by chain-drive mechanism 7.
In the present embodiment, the bolt 17, which is located on the outside of supporting plate 2, is equipped with a fastening spiral shell for preventing bolt 17 from loosening
Mother 20.
In the present embodiment, it is equipped with shield (being not drawn into figure) outside the reel 4, which is in towards headstock direction
It is streamlined.For protecting reel 4 from exposing to the weather, fairshaped shield can reduce air drag when vehicle travels.
In the present embodiment, the control button 9 is set in driver's cabin.Convenient for driver's control.
In the present embodiment, for convenient for pulling roller shutter 5,5 lower part of roller shutter is equipped with handle 21.
The effect of torsional spring 11 is to keep switch car door laborsaving.
Car door working principle: when electronic closing car door, control button 9 is pressed, controller 10 connects brake apparatus 16
With 19 circuit of electromagnetic clutch, brake apparatus 16 electric openings is braked, electromagnetic clutch 19 must be electrically coupled, by reel 4 and driven
Sprocket wheel 18 is combined together；Meanwhile controller 10 controls motor 14 and rotates, motor 14 passes through gearbox 15,7 band of chain-drive mechanism
Dynamic driven sprocket 18 rotates, and driven sprocket 18 is rotated by electromagnetic clutch 19 with movable reel 4 and spool 3, and the rotation of reel 4 makes to twine
The roller shutter 5 on reel 4 is wound on along 1 downlink of guide rail, the elongated change weight of the hanging portion of roller shutter 5, while the rotation of spool 3 drives torsional spring 11
Tightening, elastic force increase, and the gravity of 5 hanging portion of roller shutter and the elastic force of torsional spring 11 are in equilibrium state, during roller shutter 5 declines
Its gravitional force is converted into the elastic potential energy of torsional spring 11；When electric opening car door, driving device 6 drives roller shutter 5 to rise, under
Lappet divides gravity to reduce, and spool 3 drives torsional spring 11 to follow diastole, and elastic force reduces, the gravity and torsional spring 11 of 5 hanging portion of roller shutter
Elastic force still in equilibrium state, in 5 uphill process of roller shutter, the elastic potential energy of torsional spring 11 is converted into the gravitional force of roller shutter 5, volume
As long as curtain 5 overcomes the frictional force between guide rail 1 during raising and lowering, therefore, motor switch car door compares
It is laborsaving, it can energy saving.
When power failure manual switch car door, 19 power loss of electromagnetic clutch is disconnected, and reel 4 and driven sprocket 18 separate, driven
Sprocket wheel 18 and spool 3 are in rotation connection state.When pulling roller shutter 5 to close car door by handle 21, roller shutter 5 is with movable reel 4
And spool 3 rotates, the elongated change weight of the hanging portion of roller shutter 5, while the rotation of spool 3 drives torsional spring 11 to tighten, elastic force increases, volume
The gravity of 5 hanging portion of curtain and the elastic force of torsional spring 11 are in equilibrium state, its gravitional force is converted into torsion during roller shutter 5 declines
The elastic potential energy of spring 11；When pulling roller shutter 5 to open car door by handle 21, roller shutter 5 rises, and hanging portion gravity reduces,
Spool 3 drives torsional spring 11 to follow diastole, and elastic force reduces, and the gravity of 5 hanging portion of roller shutter and the elastic force of torsional spring 11 are still in flat
Weighing apparatus state, in 5 uphill process of roller shutter, the elastic potential energy of torsional spring 11 is converted into the gravitional force of roller shutter 5, roller shutter 5 rise and under
As long as overcoming the frictional force between guide rail 1 during drop, therefore, manual switch car door is also relatively labor-saving.
Adjustment the pre- torsion principle of torsional spring: when torsional spring 11 pre- torsion and roller shutter 5 weight mismatch, roller shutter 5 cannot be reached
When the gravity of hanging portion and the elastic force of torsional spring 11 are in the effect of equilibrium state, it can come by adjusting the elasticity of torsional spring 11
The pre- torsion for adjusting torsional spring 11 when adjusting the elasticity of torsional spring 11, first unclamps fastening nut 20, then with spanner rotating bolt
17, bolt 17 rotation drive torsional spring 11 rotate, so that the elasticity of torsional spring 11 is changed, when torsional spring 11 is tight its pre- torsion with regard to big,
The pre- torsion of Song Shiqi is just small, locks fastening nut 20 after adjusting again.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
