Abstract

The utility model relates to an electric bicycle handlebar with a pressure induction function. The electric bicycle handlebar with the pressure induction function comprises a body cylindrical horizontal shaft 1, two pieces of cylindrical pressure sensitive resistance strain gauges 21 and 22, two cylindrical outer leather sleeves 31 and 32 sleeving the peripheries of the cylindrical pressure sensitive resistance strain gauges, an equivalent pressure sensitive resistance strain gauge 4 formed by connecting the cylindrical pressure sensitive resistance strain gauges 21 and 22 in series, a single arm detection bridge 5 formed by other three resistors, a voltage amplification circuit 6, a voltage comparison circuit 7, a triode 8, an MCS-51 single chip microcomputer and a speed controller. When an emergency occurs, hands of a driver can increase pressure on the handlebar, the information is transmitted to the MCS-51 single chip microcomputer through the voltage detection, amplification, comparison and reverse circuits, and the MCS-51 single chip microcomputer controls the speed controller, to prevent the bursting phenomenon of the electric bicycle from happening under the emergency circumstance. According to the electric bicycle handlebar with the pressure induction function, the design is ingenious, the manufacturing is simple, and the market prospect is broad.

Description

A kind of electric bicycle handle with pressure sensitive
Technical field
The utility model relates to a kind of battery-driven car member, and particularly a kind of electric bicycle handle with pressure sensitive belongs to the technical field of battery-driven car safety traffic.
Background technology
Country advocates environment protecting and power-saving at present, and Electrical Bicycle starts more and more to be used by people.Most battery-driven car electric switch is all on handlebar on the market at present, and in use, user only needs swing handle to make easily battery-driven car move ahead.But, once be in an emergency, need to change handlebar direction in the process of moving, when changing handlebar direction through being everlasting, rotate electric switch, cause battery-driven car to accelerate, there is the quick-fried phenomenon of rushing, and cause danger.
Summary of the invention
The purpose of this utility model is to provide a kind of electric bicycle handle with pressure sensitive that increases battery-driven car driving safety.
The utility model provides a kind of electric bicycle handle with pressure sensitive, include a body, two cylindrical shape pizo-resistance strain-gaugies, two and be enclosed within the outer leather sheath of cylindrical shape handlebar of cylindrical shape pizo-resistance strain-gauge periphery and detection, control circuit part, it is characterized in that:
This body has a handlebar cylinder transverse axis, cylindrical shape pizo-resistance strain-gauge should be tightly placed in respectively handlebar two ends, left and right, and then it is peripheral that cylinder type handlebar crust cover is tightly placed in to cylindrical shape pizo-resistance strain-gauge, in conjunction with subsequent detection, control circuit, reach the object of safety traffic.
The handlebar with pressure sensitive that the utility model provides is easy to use, and modern design has the wide market space.
Accompanying drawing explanation
Fig. 1 is the utility model front elevation.
Mark in figure: 1-handlebar cylinder transverse axis; 21-cylindrical shape pizo-resistance strain-gauge; 22-cylindrical shape pizo-resistance strain-gauge; The outer leather sheath of 31-cylindrical shape handlebar; The outer leather sheath of 32-cylindrical shape handlebar.

Mark in figure: 1-handlebar cylinder transverse axis; 21-cylindrical shape pizo-resistance strain-gauge; The outer leather sheath of 31-cylindrical shape handlebar.
Fig. 3 is that the utility model detects, control circuit part.
The equivalent pizo-resistance strain-gauge that mark in figure: 4-is in series by cylindrical shape pizo-resistance strain-gauge 21 and 22; 5-Wheatstone bridge testing circuit; 6-voltage amplifier circuit; 7-voltage comparator circuit; 8-aerotron; IC is MCS-51 micro controller system.
The specific embodiment
For the ease of vehicle technology personnel, understand and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
The electric bicycle handle with pressure sensitive as shown in Figure 1, comprises handlebar cylinder transverse axis 1, two cylindrical shape pizo-resistance strain-gaugies 21 and 22, outer leather sheath 31 and 32.Outer leather sheath 31 and 32 can select soft plastic material to make, and is enclosed in cylindrical shape pizo-resistance strain-gauge 21 and 22 outside faces.
Detection as shown in Figure 3, control circuit, comprise that the equivalent pizo-resistance strain-gauge 4(21 being in series with 22 by cylindrical shape pizo-resistance strain-gauge 21 is connected with 22 use wires, not shown in FIG.) and other three resistance the Wheatstone bridge testing circuit 5, the voltage amplifier circuit 6 being formed by amplifier and resistance, the voltage comparator circuit 7 being formed by amplifier and base value voltage, aerotron 8 and the MCS-51 micro controller system that form.
Principle of work of the present utility model is: when chaufeur is driven the prominent chance of battery-driven car emergency situation, chaufeur both hands can be held handlebar.Now cylindrical shape piezoresistive wafer resistance reduces, in Fig. 3, ab both end voltage increases, after voltage amplifier circuit 6 amplifies voltages with base value voltage ratio, if handlebar pressure acquires a certain degree (can think emergency situation now occurs), now the voltage through voltage comparator circuit arrival aerotron 8 base stages will be high level, aerotron 8 current collections that are connected with MCS-51 micro controller system 12 pins (external interrupt 0 input pin) are low level very, now micro controller system enters interrupt routine, pass through internal processes, 28 15 seconds of pin auto-breaking that control is connected with external speed controller, with this, reach the generation of the phenomenon that prevents in emergency circumstances quick-fried punching of battery-driven car.
The size that the utility model can in emergency circumstances be held handlebar pressure according to different crowd regulates the size of base value voltage, with this, carrys out to judge more accurately the generation of emergency situation.Also can carry out governing speed controller power-off time by MCS-51 micro controller system internal processes, therefore, the utlity model has stronger comformability.
Whether the utility model turns to by the variation sensing handlebar of pressure, with this, controls switch state, has avoided cleverly in emergency circumstances owing to turning to, misrouting the quick-fried punching danger that moving electric switch causes.This utility model design is ingenious, implements simply, have wide market outlook.
