Description
Technical field
The present invention relates to a kind of perambulator brake structures.
Background technique
Perambulator can carry lesser perambulator progress outdoor activities for people and provide biggish convenience.Application number
106143582 B of 201610765924.X, Authorization Notice No. CN, the patent of invention of entitled " a kind of children trolley " disclose
One patent of invention: " brake assemblies include wheel connector, brake gear, limiting device, electric control mechanism, mechanical controller
Structure, brake gear include brake turntable and brake axle, and mechanical control mechanism includes the first actuator, the second actuator, operation dress
It sets, when mechanical control mechanism, which controls brake gear, to be converted from un-brake state to braking state, foot steps on operating device and drives first
Actuator rotation, so that limiting device movement be made to release the limitation to brake turntable, brake turntable rotation makes brake axle from un-brake
State is converted to braking state；When mechanical control mechanism, which controls brake gear, to be converted from braking state to un-brake state, operation
Operating device drives the rotation of the second actuator, and the rotation of the second actuator, which drives brake turntable to rotate backward, makes brake axle from brake shape
State is converted to un-brake state.The present invention can electronic and mechanical brake, can mechanical un-brake, improve the safety of children trolley
Property." the problem is that electric control mechanism and mechanical control mechanism are combined, so that structure is more complicated, processing system
It is big, at high cost to make difficulty, especially children trolley is outdoor moving product, and electric control mechanism must be from charged pool or other electricity
Source device, therefore electric control mechanism and mechanical control mechanism are combined and undoubtedly will increase cart weight, influence children and push away
The convenience that vehicle is stored and moved.In addition the structure of its mechanical control mechanism is also more complicated, and functional reliability is at doubtful.
Summary of the invention
Main inventive purpose of the invention is to provide a kind of novel perambulator brake structure.
Technical solution used in the present invention is: a kind of perambulator brake structure, including chassis, footrest component, brake cable set, brake
Vehicle side set group, brake disc；
Footrest component includes pedal, hinged seat, connection sheet, spring；
The front end of hinged seat and chassis is fixed together.Pedal is located at the lower section of the front end of chassis.The rear end of pedal and hinged seat
Front end it is hinged, the front end of foot-operated connection sheet and the rear end of pedal are articulated with the rear of the articulated shaft of both pedal and hinged seat.
Equipped with long hole, the rear end for riding connection sheet passes through the articulated shaft and hinged seat being adapted to long hole sliding for the rear end of foot-operated connection sheet
Rear end is connected.The width of foot-operated connection sheet rear end is less than the width of foot-operated connection sheet front end.Spring is nested in foot-operated connection sheet,
The rear end of spring is withstood on articulated shaft, and the front end of spring is withstood on the rear end of the front end of foot-operated connection sheet；
Brake cable set includes outside line, interior lines, and the centre bore of interior and exterior lines is slidably matched；
Brake side set group includes outer member, internals, brake pin, baffle, baffle spring.Two brake side set groups are symmetrically located at
The left and right sides of chassis, footrest component rear.Outer member indent, outer member and internals, which recline, to be fixed together.The rear end of baffle and
