Child's bicycle as a kind ofly can providing for children enjoyment of riding, temper the apparatus of children body and mind and receive the favor day by day of Modern Family.Existing child's bicycle generally comprises vehicle frame, wheel and auxiliary wheel, driving system and steering swivel system, car body is set up some protecting components to promote safety when children ride and traveling comfort.Although the structure of child's bicycle more and more rationally, safety and traveling comfort become better and better, but consider that children control the limited in one's ability of bicycle running speed, be easy to when riding speed is excessive rollover and collision case occur, this is also that the head of a family can not to one of completely relieved reason of ride, one of solution to the problems described above is on car body, install the device with automatic speed-limiting function additional, responds in time limit speed when riding speed is too fast.Existing child's bicycle does not have above-mentioned functions.
Utility model content
The utility model for solve in known technology the technical matters that exists and provide a kind of structure simple, respond sensitive, that safety the is high child's bicycle with speed limiting function.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: a kind of child's bicycle with speed limiting function comprises vehicle frame, front fork tube is provided with in the front portion of vehicle frame, front fork tube is provided with front fork, front fork is provided with front vehicle wheel, at the top of front fork, handlebar is installed; The fork body of front fork is installed with the speed sensor that detects the speed of front vehicle wheel and the speed-limit device of speed limit of carrying out braking to front vehicle wheel, speed-limit device comprises and is arranged on braking mechanism on fork body and the push-rod electric machine of driving brake mechanism action, and push-rod electric machine is fixedly mounted on fork body; Braking mechanism comprises the pedestal be fixedly mounted on fork body, pedestal is provided with mandrel, also comprise the L shape brake arm that middle part is provided with axle sleeve, axle sleeve is set on mandrel, affixed in the inner side of brake arm upper end brake shoes is installed, offers bar hole in the lower end of brake arm, be provided with pin in the end of the piston rod of push-rod electric machine, pin is positioned at bar hole; Handlebar is provided with controller, and speed sensor and push-rod electric machine are all electrically connected with controller.
Advantage of the present utility model and good effect are: the utility model provides a kind of child's bicycle with speed limiting function of structure design advantages of simple, compared with existing child's bicycle, the technical program detects the speed sensor of the speed of a motor vehicle and speed-limit device by arranging on the front fork of bicycle and arrange controller on handlebar, achieve the Automated condtrol to child's bicycle speed, when the too fast Time Controller of the speed of a motor vehicle controls speed-limit device action response, the speed of a motor vehicle is limited in ideal range, improves safety during children's riding bicycle.Be made up of push-rod electric machine and the L shape brake arm that can vert by arranging speed-limit device, achieve the technique effect that a kind of rectilinear movement by push-rod electric machine is converted into the movement of verting of brake arm, the brake shoes of brake arm upper end contacts with the wheel hub outer rim of front vehicle wheel off and on and realizes speed limit, and action response is sensitive.
Preferably: speed sensor is chosen for non-contact photoelectric speed sensor.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1 and Fig. 2, the utility model comprises vehicle frame, is provided with front fork tube 4 in the front portion of vehicle frame, and front fork tube 4 is provided with front fork 5, and front fork 5 is provided with front vehicle wheel 10, is provided with handlebar 1 at the top of front fork 5.Front fork tube 4 is fixedly mounted on the front end that vehicle frame weighs 3.
The fork body of front fork 5 is installed with the speed sensor 7 that detects the speed of front vehicle wheel 10 and the speed-limit device of speed limit of carrying out braking to front vehicle wheel 10, in the present embodiment, speed sensor 7 is chosen for non-contact photoelectric speed sensor.
As shown in FIG., speed-limit device comprises and is arranged on braking mechanism 8 on fork body and the push-rod electric machine 9 of driving brake mechanism 8 action, and push-rod electric machine 9 is fixedly mounted on fork body.Braking mechanism 8 comprises the pedestal 11 be fixedly mounted on fork body, be provided with mandrel 11-1 on the base 11, also comprise the L shape brake arm 8-2 that middle part is provided with axle sleeve 8-3, axle sleeve 8-3 is set on mandrel 11-1, affixed in the inner side of brake arm 8-2 upper end brake shoes 8-1 is installed, offers bar hole 8-4 in the lower end of brake arm 8-2, be provided with pin 9-1 in the end of the piston rod of push-rod electric machine 9, pin 9-1 is positioned at bar hole 8-4.Handlebar 1 is provided with controller 2, and speed sensor 7 and push-rod electric machine 9 are all electrically connected with controller 2.
Mode of operation: when Children Normal is ridden, speed sensor 7 detects the speed of a motor vehicle always, and detection signal is sent to controller 2, the principle of velocity measuring can be that electro-optical pickoff produces impulse singla when coordinating with wheel nave, controller 2 converts after receiving this impulse singla and draws the speed of a motor vehicle; According to preset rules, when the speed of a motor vehicle is less than certain setting value, speed-limit device does not respond; When the speed of a motor vehicle exceeds setting value, controller 2 controls push-rod electric machine 9 and responds, and the piston rod of push-rod electric machine 9 stretches out and drives brake arm 8-2 to vert centered by mandrel 11-1, the brake shoes 8-1 at top and the wheel hub edge contact of front vehicle wheel 10, produce the effect of brake, the speed of a motor vehicle is reduced; The size of controller 2 given push-rod electric machine 9 electric current depends on the speed that the speed of a motor vehicle changes, and namely when the speed of a motor vehicle improves rapidly, the speed of response of push-rod electric machine 9 also should correspondingly improve.
