Abstract
The utility model relates to an anti-theft motor for an electric bicycle. The utility model is characterized in that a normally closed switch is fixedly arranged in a housing of a motor, both ends of the normally closed switch are respectively connected with both ends of an excitation coil of the motor, and a control line of the normally closed switch penetrates through a stator axle hole leading-out cabinet along with a power cord of the excitation coil to be connected with an anti-theft controller. During normal time, the normally closed switch short-circuits the excitation coil so that the motor can not be started, and the motor can be rotated and arranged on the electric bicycle by switching off the normally closed switch through the anti-theft controller; when the electric bicycle is stolen, the normally closed switch can not be switched off because a password is unknown, the normally closed switch can not be switched off even though the control line of the normally closed switch, and the electric bicycle is difficult to move even though the electric bicycle is pedalled or pushed because the motor generates reverse electric potentials. The utility model has the advantages of artful design, simple structure, favorable anti-theft performance, etc.
Description
Technical field:
The utility model relates to a kind of motor, and the motor with theftproof performance that uses on particularly a kind of electric bicycle belongs to electric bicycle or electric motors.
Background technology:
The low-tension motor of installing and using on existing electric bicycle mainly is made up of hub, rotor, stator and magnet exciting coil, and hub and rotor are fixedly connected, and bicycle spoke is contained on the hub.After the magnet exciting coil energized, will drive rotor rotation.But itself does not all have anti-theft measure these motor, stolen in order to prevent electric bicycle, insert the mechanical type mains switch of lock core rotation and on wheel, install measure such as chain lock additional though take on the power line of motor, to be equipped with key, and these measures can not baffle the thief, make electric bicycle stolen again and again.
Summary of the invention:
The purpose of this utility model is stolen in order better to prevent electric bicycle, though stolen, motor can not rotate and design a kind ofly be skillfully constructed, simple in structure, the antitheft motor of the better electric bicycle of theftproof performance.
Technical measures of the present utility model mainly are in the motor field frame of electric bicycle normally closed switch to be housed, the two ends of normally closed switch are connected with the magnet exciting coil two ends of motor respectively, and the control line of normally closed switch passes the stator axis hole with the magnet exciting coil power line and draws casing and be connected with anti-theft controller.Described normally closed switch is the relay system normally closed switch of relay system normally closed switch or band password.This antitheft motor is contained on the electric bicycle, can makes electric bicycle have very strong theftproof performance.
The utility model since on field coil for motor normally closed switch in parallel, at ordinary times, normally closed switch is with field coil short circuit condition, motor can not be started, have only and by anti-theft controller normally closed switch is disconnected earlier, motor is rotated, be contained on the electric bicycle, if it is stolen, also can normally closed switch can not disconnected because of knowing password, be exactly the control line cut-out with normally closed switch, and normally closed switch is disconnected, i.e. use this moment is ridden or carries out also can be difficult to walking because of motor produces back electromotive force, has to be skillfully constructed, advantages such as simple in structure and theftproof performance is fine.
Description of drawings:
Accompanying drawing 1 is the electrical block diagram that the utility model uses the relay system normally closed switch;
Accompanying drawing 2 is the electrical block diagrams that use the relay system normally closed switch of band password in the utility model.
Embodiment:
Antitheft motor of the present utility model mainly is on the basis of existing motor, at the housing internal fixation of motor normally closed switch is installed and forms, and the two ends of described normally closed switch are connected in parallel with the two ends of field coil for motor respectively.Though also being contained in, this switch makes it to become antitheft motor in other motor, because of pressing for of electric bicycle, so be mainly used on the motor of electric bicycle.Described normally closed switch selects for use the normally closed switch of relay to form basic circuit as shown in Figure 1, also can on the basis of accompanying drawing 1, increase a single-chip microcomputer and form the relay system normally closed switch of band password, its circuit structure as shown in Figure 2, because of single-chip microcomputer can preset various passwords, cooperate with anti-theft controller, make the theft protection performance better.In conjunction with the accompanying drawings the utility model is further described as follows: referring to accompanying drawing 1, the two ends of the normally closed switch S of figure repeat circuit are connected in parallel with the magnet exciting coil two ends of motor M respectively, and the two ends IN of relay coil K and GND are that control line is with motor M magnet exciting coil power line V+ and V
-Passing the stator axis hole together draws casing and is connected with anti-theft controller.Referring to accompanying drawing 2, the relay system normally closed switch of band password comprises singlechip CPU and relay system normally closed switch among the figure, the two ends of the normally closed switch S of described relay are connected in parallel with the magnet exciting coil two ends of motor M respectively, the power cathode GND of singlechip CPU is connected with the end of relay coil K, the signal output part of singlechip CPU is connected with the other end of relay coil K, the power line V of singlechip CPU
CCAnd power cathode GND and the control line that is connected with the signal input part IN of single-chip microcomputer are with field coil for motor power line V+ and V
-Pass the stator axis hole together and draw casing, described control line is connected with anti-theft controller on being contained in electric bicycle.Make the single-chip microcomputer output voltage signal from anti-theft controller input setting code, make the relay adhesive, after normally closed switch S was disconnected, antitheft motor could operate as normal.The signal output part of described single-chip microcomputer is an I/O interface of single-chip microcomputer, and the signal input part of single-chip microcomputer is another I/O interface of single-chip microcomputer, and the oscillating circuit of single-chip microcomputer is identical with common circuit with reset circuit.Above-mentioned normally closed switch S and relay coil K and singlechip CPU all are fixedly mounted in the motor field frame.
