Description
Technical field
The utility model is related to haulage vehicle technical field, more particularly to a kind of electric and hand roller shutter type closed lorry body
Door.
Background technology
Van is general to set flat-open type car door behind compartment, and door leaf is to vehicle both sides when this car door is opened
Open, can not only take the car external space, and often generation passer-by or vehicle imprudence bump against the traffic thing of car door
Therefore, there is potential safety hazard；Secondly, during opening car door typically manually, more bother, compartment is opened using electronic mode
Door is more convenient, but flameout state is typically in during lorry handling goods, and electronic mode opens car door and provides electricity by battery
Power, such as battery power deficiency, still needs to open car door using manual mode.
Utility model content
The utility model overcomes the deficiencies in the prior art, and there is provided a kind of roller shutter type closed lorry body of electric and hand
Door, can avoid the problem of car door of traditional flat-open type is easily bumped against after opening by pedestrian or vehicle, beneficial to traffic safety, may be used also
Car door is opened using electronic mode or manual mode.
The utility model is achieved through the following technical solutions：
A kind of electric and hand roller shutter type closed lorry body door, including it is rolling screen guiding rail, support, spool, reel, roller shutter, flat
Face scroll spring, energization mating type electromagnetic clutch, drive device, limiter, controller and operation button；The rolling screen guiding rail
Be divided into both sides on rear side of compartment casing, support is fixedly arranged on the compartment casing both sides above rolling screen guiding rail, spool be located at support it
Between be connected with holder pivots, drum sheath outside spool and spool rotate connection；The roller shutter by multiple strips curtain sheet phase
Mutually it is hinged and is in series, the roller shutter is wrapped on reel and can slided up and down along rolling screen guiding rail；The plane scroll spring is located at
In reel, one end of the plane scroll spring is fixedly connected with spool, and the other end is fixedly connected with mandrel interior wall；The electromagnetism from
Clutch is located at reel one end, and its driven disc is fixedly connected with reel, and its driving disc spacing pressing is fixedly connected with spool, the electromagnetic clutch and
Controller is electrically connected；The drive device is provided with motor, reduction box and brake gear, the motor and controller electrical connection and by
It is controlled, and the input of reduction box connects the output shaft of motor, output end and spool drive connection, brake gear connection motor
Rotating shaft and and controller electrical connection；For controlling, roller shutter rising is automatically stopped position to the limiter and decline is automatically stopped position
Put, the limiter and reduction box drive connection, and controller electrical connection；Operation button and the controller electrical connection, and pass through
The working condition of controller controlled motor.
During using electronic mode switch car door, electromagnetic clutch, electromagnetic clutch are connected by operation button via controller
Device, which is powered, to be combined, and driving disc spacing pressing and driven disc link into an integrated entity, i.e. spool and reel links into an integrated entity, and controller is also turned on brake
Device and motor circuit, brake gear open brake, and motor drives spool turns by reduction box, is wrapped in the roller shutter on reel
Risen or fallen along rolling screen guiding rail, so as to open or close car door, now spool and reel are rotated together, plane scroll spring
Do not work；Set limiter that roller shutter can be allowed to be automatically stopped in stop position set in advance, without to pass through every time

It can rotate, now brake gear no power, can not be rotated in braking state, i.e. spool around spool, during manual-lock car door,
The hanging portion of roller shutter is elongated, and the deadweight of its hanging portion is also increased, and spool turns drive plane scroll spring to tighten up, and its elastic force increases
Greatly, the elastic force of the deadweight of roller shutter hanging portion and plane scroll spring is in poised state, its gravitational potential during roller shutter declines
The elastic potential energy of plane scroll spring can be converted into；During manually opened car door, roller shutter rises, and the deadweight of its hanging portion reduces,
Reel drives plane scroll spring to follow diastole, and its elastic force reduces, the deadweight of roller shutter hanging portion and the bullet of plane scroll spring
Power is still in poised state, and in roller shutter uphill process, the elastic potential energy of plane scroll spring is converted into the gravitional force of roller shutter, volume
As long as curtain overcomes the frictional force between rolling screen guiding rail during raising and lowering, switch car door is very light.
Further, the operation button is in driver's cabin.It is easy to driver's control.
Further, the reel is rotated by bearing and spool and connected.Spool turns can be made more smooth.
Further, the spool is connected by bearing and holder pivots.
Further, protective cover is provided with outside the reel and drive device, the protective cover is in the streamline towards headstock direction
Type.For protecting reel and drive device from exposing to the weather, fairshaped protective cover can reduce air resistance when vehicle is travelled
Power.
Further, the reduction box is connected by chain-drive mechanism and reel；The chain-drive mechanism includes being located at
Drive sprocket on reduction gearbox output shaft, the driven sprocket on spool, the chain for connecting drive sprocket and driven sprocket.
Further, the roller shutter bottom is provided with handle.
The beneficial effects of the utility model are：The car door that can avoid traditional flat-open type using the car door of roller shutter type is opened
The problem of easily being bumped against afterwards by pedestrian or vehicle, beneficial to traffic safety；Reel is arranged on vehicle exterior, is not take up interior empty
Between；Reel and spool is set to combine and separate under the control of the controller using electromagnetic clutch, can motor switch compartment when having an electricity
Door, when electric power is not enough can hand switch car door, manual and electric automatically switches, very convenient；Using plane scroll spring power-assisted
Spool turns, make hand switch car door very laborsaving.
