Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
The present embodiment comprises brake mount 2, first strut 3, second strut 5, first brake component 6, second brake component 7, sheet 4 is stepped in braking, car body attaching parts 1 and damping spring 8, brake mount 2 comprises two, be located on the main shaft of the relative side of perambulator two rear wheel respectively, two brake mounts 2 are connected by the first strut 3, two brake mounts 2 are connected to first brake component 6, side near wheel on first brake component 6 is provided with outwardly directed slipper, two the first brake components 6 are connected by the second strut 5, braking is stepped on sheet 4 one end and is flexibly connected with the first strut 3, can rotate around the first strut 3, the other end is fixedly connected on the second strut 5, second brake component 7 comprises two, is installed between stroller rear wheels and brake mount 2 respectively, and the second brake component 7 is provided with V-arrangement position-limited trough that is along the circumferential direction multiple and that slipper can be blocked, car body attaching parts 1 is fixed on brake mount 2, and connecting portion arranges damping spring 8.
In the present embodiment, the cavity 22 that brake mount 2 comprises upper opening and the first strut connecting portion 21 be located at outside cavity, inside cavity is provided with the first positive stop lug boss 23 installing damping spring 8.
In the present embodiment, second brake component 7 is by cylindrical body 71 and be evenly arranged on multiple positioning plates 72 that body cylindrical face is radially stretched out and form, the end 73 of positioning plate 72 is the face of cylinder, forms the V-arrangement position-limited trough that slipper can be blocked between adjacent two positioning plates.
In the present embodiment, the first brake component 6 is channel, and notch is downward, and end is hinged on brake mount 2, and can rotate in the plane perpendicular to the first strut 3 axis, front end connects the second strut 5; Slipper 61 outside first brake component 6 is located at the position corresponding with the position-limited trough on the second brake component 7, two ultimate limit state is: when the first brake component 6 is positioned at lowest part, below the notch place that slipper 61 is positioned at V-arrangement position-limited trough or notch, to stop the rotation of wheel; When the first brake component 6 turns to highest point, slipper leaves position-limited trough, beyond the rotary area being positioned at the second brake component 7.
In the present embodiment, car body attaching parts 1 lower end is located in the cavity of brake mount 2, and be provided with the second positive stop lug boss 11 for installing damping spring 8 bottom it, upper end is tubular car body connecting portion.
In the present embodiment, damping spring 8 two ends are set on the first positive stop lug boss 23 and the second positive stop lug boss 11 respectively.

The principle of work of the present embodiment is: when perambulator needs brake, tramp with one's feet on brake-apply near second strut one end, second strut is moved downward, thus drive first brake component at the second strut two ends to be rotated down, in the process that the first brake component is rotated down, the slipper of its side can snap in the V-arrangement position-limited trough of the second brake component, limits the rotation of the second brake component, also just prevent the rotation of rear wheel, thus reach the effect of braking.
When needing releasing of brake, tramp with one's feet the curved portions of brake-apply end, second strut is upwards lifted, the first brake component is driven upwards to rotate, in the process that the first brake component upwards rotates, the slipper of its side can depart from the V-arrangement position-limited trough of the second brake component, and brake off block to the restriction of the second brake component, thus enables rear wheel normal rotation.
Comprehensive technique scheme and principle of work can be found out, when braking, only need once to trample brake pedal with pin, two trailing wheels just can be braked simultaneously, its braking effect is better than the braking effect be placed on wheel that brakes, and improves the safety in perambulator operational process.
Be provided with damping spring at the connecting portion of car body attaching parts and brake mount simultaneously, when jolting appears in vehicle, good cushioning effect can be played, improve the traveling comfort of perambulator.
