Detailed description of the invention

Below in conjunction with accompanying drawing and example, the specific embodiment of the present invention is further described, but protection domain of the present utility model should not be limited with this.

Fig. 1 is the Electrical Bicycle safety locking motion scheme of installation of the present embodiment

Fig. 2 is the Electrical Bicycle safety locking motion circuit theory schematic diagram of the present embodiment

As shown in Fig. 1, Fig. 2, Electrical Bicycle safety locking motion 100, comprising:

Be arranged at the ultrasonic fault detection annunciator 10 on Electrical Bicycle forward safety bar, be arranged on the front bumper/spoiler of Electrical Bicycle, ultrasonic fault detection annunciator 10 has selection setup unit, setup unit is selected to be positioned on the gauge panel of Electrical Bicycle, the distance of obstacle alarm is detected for setting Electrical Bicycle

Be arranged under Electrical Bicycle seat normal open switch 20,

Relay 30, is arranged in the space at Electrical Bicycle seat, and relay has two to control contact, and one group controls contact 31 and connects with normal open switch 20; One group controls contact 32 for controlling the operation of motor M in pull up circuit; Relay and normal open switch, the common composition control circuit of electric door lock terminals of Electrical Bicycle.

As shown in Figure 2, the circuit connecting mode of the electric door lock terminals of Control terminals and Electrical Bicycle is series connection;

Annunciator 40, is arranged on the gauge panel of Electrical Bicycle, the master cock of annunciator 40 is controlled by electric door lock SB, with relay 30 control terminals between switch interlock.When electric door lock key insertion torsion makes SB switch close, the master cock of annunciator 40 also can be made to close, and triggered alarm 40 conducting is reported to the police.

Fig. 3 is normal open switch structural representation in Electrical Bicycle safety locking motion of the present utility model

Wherein, normal open switch 20 is spring pressure master cock, comprise moving conductive sheet 21 and quiet conducting strip 22, moving conductive sheet and quiet conducting strip have moving conductive contact surface 211 and quiet conductive contact surfaces 221, it is the zig-zag cooperatively interacted, can contact surface be increased, the situation causing electrical contact bad because changing-over is frequently touched can be reduced in use; Moving conductive sheet is for falling " mountain " font, and its both sides are conductive contact surfaces 211, and centre is guard bar 212, guard bar are socketed with pressure spring 213, and middle guard bar 213 is not damaged by pressure by the body weight pressure of rider for the protection of moving conductive sheet 21 and quiet conducting strip 22;

Quiet conducting strip 22 bottom is connected with metallic conduction stage clip 222, for keeping the good contact of the conductive contact surfaces of 21 moving conductive sheets and quiet conducting strip 21.

Electrical Bicycle safety locking motion circuit theory schematic diagram below in conjunction with Fig. 2 describes principle of work and the process of the present embodiment in detail.

As shown in Figure 2, SQ represents normal open switch, and FU represents fuse, and FR represents thermal relay

The total lock of QS circuit be connected with in figure in the pull up circuit of motor M is all generally closure state,

When people sits on the seat, the body weight pressure of people can force normal open switch 20 to close, and now rotates key SB: the electric door lock terminals switch of Electrical Bicycle is closed, the coil of KM1 obtains electric, and the open contact 31,32 of KM1 closes, pull up circuit is connected, and Electrical Bicycle runs; Annunciator 40 is connected and is reported to the police simultaneously.

Close key switch SB, now the winding wiring of relay K M1 is in on-state, the coil electricity of KM1 with normal open switch 20, and control contact 31,32 or close, motor still operates; But now, annunciator 40 disconnects, and does not report to the police.

Only have people to leave seat, SQ disconnects, and whole circuit just disconnects.

In the process of moving, ultrasonic fault detection annunciator 10 can be provided working parameter in advance, as induction alarm distance, when the distance of electrical salf-walking front side and obstacle meet arrange require time, ultrasonic fault detection annunciator 10 meeting alarm, this arranges and is mainly applicable to walk while when talking chat with people, can knock preceding object thing by mistake when rider pushes Electrical Bicycle, accidents caused.

The effect of embodiment and effect

According to the Electrical Bicycle safety locking motion that the present embodiment provides, use normal open switch series connection access by the control circuit of Control: under normal open switch being arranged at Electrical Bicycle seat, the presence or absence of pressure when utilizing rider to drive and leave is to control the work of pull up circuit; Ultrasonic fault detection annunciator is arranged at the front of Electrical Bicycle, when electrical salf-walking front side ultrasonic fault detection annunciator sense with the distance of obstacle meet arrange require time, ultrasonic fault detection annunciator meeting alarm, this arranges and is mainly applicable to walk while when talking chat with people when rider pushes Electrical Bicycle, careless and inadvertent and cause collision case.

The same electric door lock simultaneously used and alarm circuit part, remind rider to be transferred to by electric door lock key, after transfering to, annunciator stop alarm can prevent key potential safety hazard stolen onboard and child from playing with the accidents caused risk of key.

Moving conductive sheet in normal open switch and the conductive contact surfaces of quiet conducting strip are the zig-zag cooperatively interacted; for during contact-enhancing in conjunction with firmness; the middle guard bar simultaneously used is not damaged by pressure by the body weight pressure of rider for the protection of moving conductive sheet and quiet conducting strip, extends the service life of normal open switch.

These are only better embodiment of the present utility model, be not used for limiting practical range of the present utility model.Have in any art and usually know the knowledgeable, not departing from thinking of the present utility model and scope, when doing various changes with flexible, therefore protection domain of the present utility model should be as the criterion with claims institute confining spectrum.
