Accompanying drawing explanation
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is the principle schematic of the first embodiment of the present invention.
accompanying drawing 3 is the principle schematic of the second embodiment of the present invention.
in accompanying drawing: 1, vehicle frame; 2, seat; 3, handle; 4, brake gear.
Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
a kind of children trolley, it comprise be provided with seat 2 vehicle frame 1, connect the handle 3, brake gear 4, the warning device that are arranged on vehicle frame 1.
brake gear 4 comprises the band-type brake be arranged on trailing wheel and the parking brake be connected with band-type brake by connecting rope.Parking brake can be arranged on each place of vehicle frame 1.Under normal operation, hand is placed on handle and carries out children trolley by operating personal, and when operating personal needs to leave go-cart, actuating parking brake makes band-type brake action, ensures that trailing wheel is in locking state.
warning device comprise be arranged on seat 2 and be triggered when seat 2 existing children and the trigger switch of action, arrange on the handle 3 for perception hand whether the first determining device on the handle 3, be arranged on brake gear 4 for perception brake gear 4 whether the second determining device of action and an annunciator.Annunciator can be ring device.When being in operating state, ring device carries out thundering to remind operating personal.Warning device can also be warning light, on the handle that warning light can be arranged on children trolley or other positions, and when being in operating state, warning light flicker is used for reminding.
trigger switch can be formed by gravity detector and with the electronic switch that this gravity detector is connected.Trigger switch passes through to the Gravity observation on seat 2 to realize triggering or closing, when trigger switch detects that the gravity that seat 2 bears is non-vanishing, and electronic switch closes, trigger switch activation; When to monitor gravity that seat 2 bears be zero to trigger switch, electronic switch is opened, and trigger switch is failure to actuate.
trigger switch also can have the source switch of actual configuration.When child is sitting on seat 2, the button of source switch is pressed, source switch closes, and trigger switch activation, when child leaves seat 2, the button of source switch is upspring, and source switch is opened, and trigger switch is failure to actuate.
first determining device is the inductor for perception human body.The various device structures for measuring human body such as this inductor can be measured by employing human body infrared, the mechanical measurement of handrail.When hand not on the handle 3 time, first determining device detect result be true, when hand is positioned on handle 3, first determining device detect result be true.
second determining device is the detecting device for perception brake gear 4 whether action, and the result detected is passed to annunciator.When brake gear 4 is failure to actuate, the testing result of the second determining device is true.When brake gear 4 action, the testing result of the second determining device is not true.
when after trigger switch activation, the first determining device by the hand detected whether result be on the handle 3 passed to annunciator, the result of the brake gear 4 detected whether action is passed to annunciator by the second determining device.When the testing result of the first determining device and the second determining device is all true time, annunciator carries out actuation of an alarm, when the first determining device and the second determining device testing result at least one be not true time, annunciator is failure to actuate.
the difference of second embodiment of the invention and the first embodiment is: warning device comprise be arranged on seat 2 be triggered when seat 2 existing children and the trigger switch of action, arrange on the handle 3 for perception hand whether the first determining device on the handle 3, be arranged on for perception brake gear 4 whether the second determining device of action and an annunciator on brake gear 4, trigger switch, the first determining device and annunciator form C/LOOP.
the result "True" that second determining device detects represents brake gear 4 and is failure to actuate.During brake gear 4 action, the testing result of the second determining device is not true.
first determining device is touch switch, and when hand is positioned on handle 3, touch switch is opened; When hand departs from handle 3, touch switch closes; When trigger switch activation and the touch switch of described first determining device closes time, the result of the brake gear 4 detected whether action is passed to annunciator by described second determining device, if the result that the second determining device detects is true, described annunciator carries out actuation of an alarm; If the result that one of trigger switch, touch switch are not operating or the second determining device detects not is true time, described annunciator is failure to actuate.
above specific embodiment of the present invention is illustrated in conjunction with diagram, clearly on the basis not leaving scope and spirit of the present invention, much can revise prior art and technique.In art of the present invention, the usual knowledge of a GPRS, just within the scope of technology main idea of the present invention, can carry out diversified change.
