the working process of this braking mechanism is:
when braking mechanism needs from braking state during un-brake, now ratchet 33 is fastened on one of them the 3rd helical teeth groove 341b on runner 34, in 342b, first ratchet 351 is fastened in one of them first helical teeth groove 341a, and the tooth top of the first ratchet 351 is to the bottom land 341a-1 position being located at the first helical teeth groove 341a, second ratchet 361 is fastened in one of them second helical teeth groove 342a, and the tooth top of the second ratchet 361 is to the bottom land 342a-1 position being located at the second helical teeth groove 342a, step on brake 32, brake is rotated 32 and is driven ratchets 33 to rotate, runner 34 is driven to rotate when ratchet 33 rotates, the cooperation that runner 34 rotates through the first ratchet 351 and the first helical teeth groove 341a is ordered about the first actuator 35 and is slided, order about the second actuator 36 by the cooperation of the second ratchet 361 and the second helical teeth groove 342a to slide, and the tooth top of the first ratchet 351 is slided from the bottom land 341a-1 of the first helical teeth groove 341a to groove top 341a-2, until the limit rib at the tooth top of the first ratchet 351 and the first 341a-2 position, helical teeth groove 341a groove top offsets, the tooth top of the second ratchet 361 slides from the bottom land 342a-1 of the second helical teeth groove 342a to groove top 342a-2, until the limit rib at the tooth top of the second ratchet 361 and the second 342a-2 position, helical teeth groove 342a groove top offsets, in this process, the direction of slip of the first actuator 35 and the second actuator 36 is contrary, in the process that first actuator 35 and the second actuator 36 slide, the trailing cable 22 of both sides is stretched, the trailing cable 22 of both sides pulls the unlock piece 21 of both sides respectively, the unlock piece 21 of both sides is rotated relative to wheel joint 41, in the process that unlock piece 21 rotates, order about brake component 1 slide and locked groove gradually on separating wheel by coordinating of unlock piece 21 and brake component 1, until the locked groove on the complete separating wheel of brake component 1, this braking mechanism is just in the state of un-brake, that is wheel can rotate relative to car body.
now releasing of brake is 32, brake resets to counter-rotation under the effect of the second reposition element 38 32, brake is in 32 counter-rotational processes, runner 34 relatively car body 4 maintains static, ratchet 33 is gradually from one of them runner 34 the 3rd helical teeth groove 341b, deviate from 342b, along with brake is the rotation of 32, under the effect of the first reposition element 37, ratchet 33 enters and one of them the 3rd helical teeth groove 341b, the next one the 3rd helical teeth groove 341b that 342b is adjacent, in 342b, now due to runner 34, car body 4 is fixing relatively, trailing cable 22 is in the state be stretched all the time, braking mechanism is in un-brake state.
when needs brake, again step on brake 32, brake 32 rotations, ratchet 33 is driven to rotate, runner 34 is driven to rotate when ratchet 33 rotates, the first ratchet 351 is made to enter in the next one first helical teeth groove 341a adjacent with one of them the first helical teeth groove 341a, second ratchet 361 enters in the next one second helical teeth groove 342a adjacent with one of them the second helical teeth groove 342a, runner 34 rotates, order about the first actuator 35 by the cooperation of the first ratchet 351 and the first helical teeth groove 341a to slide, order about the second actuator 36 by the cooperation of the second ratchet 361 and the second helical teeth groove 342a to slide, and the tooth top of the first ratchet 351 is slided from the groove top 341a-2 of the first helical teeth groove 341a to bottom land 341a-1, until the tooth top of the first ratchet 351 and the first helical teeth groove 341a bottom land 341a-1 offset, the tooth top of the second ratchet 361 slides from the groove top 342a-2 of the second helical teeth groove 342a to bottom land 342a-1, until the tooth top of the second ratchet 361 and the second helical teeth groove 342a bottom land 342a-1 offset, that is the direction of slip of now the first actuator 35 and the second actuator 36 is contrary with direction of slip during un-brake, and the direction of slip of the first actuator 35 and the second actuator 36 is contrary, in the process that first actuator 35 and the second actuator 36 slide, the trailing cable 22 of both sides is relaxed, thus the power making unlock piece 21 act on brake component 1 disappears, brake component 1 slides to the direction of inserting locked groove until insert in locked groove under the effect of the 3rd actuator 23 elastic force, braking mechanism is just in the state of brake.
now releasing of brake is 32, brake resets to counter-rotation under the effect of the second reposition element 38 32, brake is in 32 counter-rotational processes, runner 34 relatively car body 4 maintains static, ratchet 33 is gradually from one of them runner 34 the 3rd helical teeth groove 341b, deviate from 342b, along with brake is the rotation of 32, under the effect of the first reposition element 37, ratchet 33 enters and next 3rd helical teeth groove 341b, next again the 3rd helical teeth groove 341b that 342b is adjacent, in 342b, now due to runner 34, car body 4 is fixing relatively, trailing cable 22 is in lax state all the time, braking mechanism is in braking state.
to sum up, braking mechanism structure of the present invention is simple, makes the wheel of both sides be in brake and un-brake state by driver train simultaneously, easy to operate, and brake and un-brake all needing people for stepping on brake handle, thus can maloperation be avoided, improving the safety performance of this braking mechanism use.
the invention also discloses a kind of children trolley, this children trolley has above-mentioned braking mechanism, and because braking mechanism has above-mentioned technique effect, therefore the children trolley with this braking mechanism also has above-mentioned technique effect.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
