Description
Technical field
The utility model is related to braking technology field, more particularly, to a kind of gravity from perambulator of stopping.
Background technology
Perambulator be it is one main kind of among toy for children, including child's bicycle, children trolley, baby walker,
Child's tricycle, five major class of children's electric motor vehicle, brake structure are typically around adult's design, and there has been no a special at present
For the brake gear that children design, as shown in Figure 1, existing child's tricycle is when descending, the slightly careless feelings of adult
Under condition, perambulator accelerates to glide, because not braking, causes child to be easy to wrestling injured.
Disc brake, drum brake on existing brake gear such as motor vehicle, circuit is complicated, and cost is higher, is mounted on carriage for children
It is impracticable, and the brake of bicycle is then to affect brake cable by brake lever, tenses brake, brake friction steel ring can brake
, installation is simple, but the child's age for generally playing perambulator is too small, and some possibility have just started to walk, thus will not make
With brake, and hand strength is also inadequate.
It is operated without children's trick therefore, it is necessary to design one kind on carriage for children, and the automatic device that can be braked.China
Patent 200920191953.5 discloses a kind of automatically operated retarder, it is one pendulum of setting, pendulum on the vehicle frame of tourist coach
Hammer can according to the principle that tourist coach the state swing that lands, straight down according to gravity direction, when tourist coach is in level road
When upper, the angle on plumb-bob gravity direction and ground is 90 degree, and when tourist coach is gone down hill, pendulum is relative to tourist coach to forward swing
Dynamic, the angle degree that pendulum is swung is the angle degree of the gradient.Add the brake of a connection pendulum in the original brake of tourist coach
Fare, when tourist coach is gone down hill, pendulum swings to tense brake cable forward, to achieve the purpose that downhill retardation, when
When tourist coach walks level road or goes up a slope, pendulum is in relaxation state with brake cable, and the original brake system of tourist coach is unaffected.But
Since pendulum is to utilize gravity, and it is installed additional on former vehicle in the patent, pendulum can be produced in normally travel
Pendulum is transported afterwards before death, to influence normal driving.
Invention content
The utility model is at least one defect overcome described in the above-mentioned prior art, in conjunction with gravity, lever principle
