Abstract
The utility model discloses a safe laborsaving bicycle has linked firmly reverse flywheel 1 on its sprocket center pin 2, the tooth of flywheel 1 links firmly with coaxial flywheel overcoat 3, overcoat 3 has the one end hinge of free bearing 26 and helping hand connecting rod 4, the other end of connecting rod 4 and the one end hinge of the rigidity 25 of gravity seatpad 12, the other end of rigidity 25 and the counter roll 24 hinge of seat frame 11, there are reset spring 5 to connect seat frame 11 and connecting rod 4, center pin 2 passes through bearing 27 and is connected with link 10, the tooth of the angle flywheel 6 that its both ends linked firmly is connected with flywheel housing 9, flywheel housing 9 passes through positioning spring 8 and connected to the frame, there is sprocket 28 on the center pin 2 to pass through the chain and is connected with the epaxial flywheel of rear wheel. The gravity of the human body can be continuously converted into the driving assistance, and the device is safe and labor-saving.
Description
The utility model is relevant with morpet, and is especially relevant with the bicycle that the safety labor-saving device is housed.
Existing bicycle power-assisted device utilizes the body weight for humans masterpiece to be used for the trailing wheel driving system.Gravity by vehicle seat, reaction spring, vibrating arm, lever, quadrant gear, transition gear, be used to wheel, bevel wheel is delivered on the pedal spindle.Complex structure, manufacturing cost height, maintenance difficult.
The purpose of this utility model provides a kind of simple in structure, and power-assisted is reliable, firmly economizes comfortable, the safety of riding, safety labor-saving bicycle with low cost.
The utility model is achieved in that
Be fixed with reverse flywheel 1 on the centre of sprocket axle 2 of safety labor-saving bicycle, the tooth of flywheel 1 is connected with coaxial Case of fly-wheel 3, overcoat 3 has a free bearing 26 and an end of power-assisted connecting rod 4 to be hinged, one end of the rigid pipe 25 of the other end of connecting rod 4 and gravity seat cushion 12 is hinged, the fulcrum 24 of the other end of rigid pipe 25 and seat frame 11 is hinged, there is retracing spring 5 to connect seat frame 11 and connecting rod 4, center shaft 2 is connected with link span 10 by bearing 27, the tooth of the angle flywheel 6 that its two ends are connected is connected with flywheel sleeve 9, flywheel sleeve 9 connects to ground by retainer spring 8, has sprocket wheel 28 to be connected with flywheel on the hind axle by chain on the center shaft 2.
There are hinge 30 and lifting bar 17 to be hinged on the lifting wheel mount board 20 on the back vehicle frame 29, bar 17 lower ends are connected with lifting wheel 16, the upper end has driving lever 31 to be connected with location drag hook 21, have fall a spring 18 with the back vehicle frame be connected, drag hook 21 is hinged with axle 32, and its other end is connected with lifter drawing bar 22 by backguy 33, and pull bar 22 is hinged with vehicle frame, have button 34 to cooperate with bar 35, bar 35 brakes with safety wheel by backguy and is connected 23.
Have depression bar 36 and axle 32 to be hinged, the one end is connected with driving lever 31, and the other end connects to ground by spring 19.Rigid pipe 25 is a plate shape, foam layer is arranged below it.
The utility model is used for transmission mechanism of bicycle by pull bar with the body weight for humans masterpiece, and its transmission frequency is identical with people's pedal frequency.Because exchange about foot-operated power is continuous makes human body gravity constantly form the centre of sprocket axle that power-assisted acts on car, the laborsaving light power of riding is brisk.Foot-operated power is down the time, and the angle flywheel drives the work done of centre of sprocket axle, and when pedal was not subjected to strength of one's legs, retainer spring resetted in effectively doing the force it, therefore need not finish a week by bike the time after, pin is just got back to fine piece of writing power position, and is laborsaving.Emergency brake in danger when riding, lifting wheel lands, and makes car keep balance, and car and people do not fall, safety.
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is pedal structure figure.
Fig. 3 is the lifting wheel constructional drawing.
Following is embodiment of the present utility model:
Oppositely flywheel 1 is the ordinary bicycle flywheel, but oppositely is installed on the center shaft 2, and overcoat 3 is integral with flywheel 1 suit.Connecting rod 4 and overcoat 3 welding.Retracing spring 5 is installed between seat frame 11 and the connecting rod 4.During angle flywheel 6 is installed on the two ends of axle 2.Overcoat 9 is set on the flywheel 6, and foot-driven lever 7 overcoats 9 connect.Retainer spring 8 is connected between overcoat 9 and the seat frame 11, makes foot-driven lever reset in fine piece of writing force (with about 30 degree of horizontal sextant angle).The axle mounting of lifting wheel 16 is on lifting bar 17.Fall a spring 18, raise-position spring 19 and be installed on the vehicle frame of back, be connected with depression bar 36 with lifting bar 17 respectively.Lifting bar 17 is installed on the bearing carrier ring of plate 20.Depression bar 36, driving lever 31 be installed on the plate 20 the axle 32 on.On the seat messaging backs 13 is installed, two beads of one can be massaged the human body waist when beautiful car.Rotary parasol 14 and suitcase 15 are installed on the car.
