[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in the figure, a kind of braking device for children's vehicles includes main brake 7 and auxiliary brake 8.Described main brake 7 comprise the brake disc 1 of captiveing joint with wheel hub 3 and with the center shaft bonded assembly wheel carrier 2 of wheel hub 3.Be evenly equipped with spoke hole 11 at brake disc 1 periphery, be hinged with brake pedal 4 on wheel carrier 2, brake pedal 4 can rotate around its hinge-point.
Be provided with containing cavity 41 on brake pedal 4, be placed with movable block 5 slidably in containing cavity 41, this movable block 5 is coaxial with the hinge-point that brake pedal 4 is hinged on the wheel carrier 2.Movable block 5 can rotate at containing cavity 41, also can move along containing cavity 41 inwalls.
Also be provided with the stay cord 9 of pulling auxiliary brake 8 on brake pedal 4, when depressing 7 brakes of brake pedal 4 realization main brakes, stay cord 9 also spurs auxiliary brake 8 brakes.
Be respectively equipped with back-up block 42 in the relative both sides of described containing cavity 41 inwalls, this back-up block 42 include a step 421 and with step 421 bonded assembly inclined thrust surfaces 422.Described movable block 5 includes plane 51 that can be supported on the step 421 and the mobile inclined thrust surface 52 that cooperates and movable block 5 is moved around with inclined thrust surface 422 in containing cavity 41.In the present embodiment, described inclined thrust surface 422 is the bevelled arcwall face, and described mobile inclined thrust surface 52 is and the opposite arcwall face of inclined thrust surface 422 direction of tilt.
Described movable block 5 also includes projection 54, is provided with the guide groove 61 that movable block 5 is moved as straight line on surface cover 6, and projection 54 places guide groove 61 and moves along guide groove 61.When movable block 5 relatively rotates in containing cavity 41 like this, under the effect of inclined thrust surface 422 and mobile inclined thrust surface 52, make movable block 5 do to move around at containing cavity 41.
Be fixedly connected with the locking bar 53 that can pass containing cavity 41 and place spoke hole 11 in described movable block 5 inner ends, also be provided with the surface cover 6 that covers containing cavity 41, be provided with top pressure spring 7 between the outer end of movable block 5 and the surface cover 6 at wheel carrier 2.
In the time will realizing braking, depress brake pedal 4, then brake pedal 4 can rotate around its hinge-point, then containing cavity 41 rotates toward clockwise direction, and movable block 5 can not rotate under guide groove 61 effects of surface cover 6, and the plane 51 of movable block 5 just no longer is supported on the step 421 of back-up block 42 like this.In case plane 51 breaks away from step 421 fully, movable block 5 is moved forward, final movable block 5 enters in the containing cavity 41 fully.Simultaneously the locking bar 53 on the movable block 5 also and then moves and passes containing cavity 41 and insert in the spoke hole 11, makes it to limit the effect of wheel hub 3, realizes brake function.
When wanting releasing of brake, brake pedal 4 is up lifted, and then containing cavity 41 is toward anticlockwise motions, and movable block 5 can not rotate under guide groove 61 effects of surface cover 6.Make inclined thrust surface 422 do relative slip like this with mobile inclined thrust surface 52, under two inclined thrust surface interaction forces, make movable block 5 withdraw from containing cavity 41, the locking bar 53 on the movable block 5 also and then shrinks back simultaneously backward, makes locking bar 53 withdraw from spoke hole 11 and also finally withdraws from the containing cavity 41.The restriction that locking bar 53 is broken away from wheel hub 3 realizes the releasing of brake function.
In order to depress or up to lift when drawing brake pedal 4 exactly, can realize brake or releasing of brake function exactly.So be provided with the cylinder 62 of hollow at described surface cover 6 medial surfaces, in cylinder 62, be provided with compression spring (not shown) and roof pressure post 622 successively, on brake pedal 4, containing cavity 41 outsides be provided with two the location counterbores 43, roof pressure post 622 under the effect of compression spring roof pressure therein one the location counterbore 43 in.When depressing brake pedal 4 like this, roof pressure post 622 contracts inward, is rotated further brake pedal 4, make roof pressure post 622 come another location counterbore 43, and under the effect of compression spring, roof pressure post 622 being withstood in the counterbore 43 of location, the user just can know and realized brake function exactly.Equally, when brake pedal 4 rotates toward opposite sense, roof pressure post 622 breaks away from location counterbore 43, be rotated further brake pedal 4, make roof pressure post 622 come another location counterbore 43, and under the effect of compression spring, make roof pressure post 622 withstand on that the user just can know and realized the releasing of brake function exactly in the counterbore 43 of location.
