Abstract
The utility model discloses a kind of brakes to power off inductive switch, it is characterized in that, controller, sensor magnet and magnetic detecting element including being integrated in pcb board, magnetic detecting element and controller electrical connection, sensor magnet is under the action of brake cable, horizontal displacement is generated relative to magnetic detecting element, which is in the Mechanical Contact state that is not present, and structure is simple, compact, control signal reliability are good.
Description
Technical field
The utility model relates to electric accessory motor field, in particular to a kind of brake powers off inductive switch.
Background technique
Most of the brake lever of existing electric bicycle is to have filled the dedicated brake lever of electric vehicle (having mechanical switch) or even do not installed
Cut-off switch.When riding electric bicycle, cyclist often do not stop pedaling yet while brake step on it is foot-operated or not loose
Electric switch handle is opened, at this point, controller still gives always the high-power power supply of motor, the quality of brake power-off switch directly returns influence vehicle
The service life of son and the life security of user, the reaction brake lever that is insensitive or even not filling cut-off switch of standard machinery switch
Motor can be caused " stall " occur, make motor, battery, controller by heavy current impact so that damage, also makes the zero of bicycle
Part is impaired, while braking effect of serious failure can jeopardize safety.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of brakes to power off inductive switch, which is in and does not deposit
In Mechanical Contact state, structure is simple, compact, control signal reliability are good, caused by the prior art above-mentioned to solve
Multinomial defect.
A kind of brake that achieve the above objectives, the present invention provides the following technical solutions: powers off inductive switch, including
It is integrated in the controller, sensor magnet and magnetic detecting element of pcb board, magnetic detecting element and controller electrical connection, sensor magnet exist
Under the action of brake cable, horizontal displacement is generated relative to magnetic detecting element.
Preferably, brake power-off inductive switch further includes shell, brake handle and component accommodating cavity, brake relative to
Housing hinge, component accommodating cavity are located at the lower section of shell；The end of brake handle is arranged in the brake cable, is equipped with and slides in shell
Slot, sensor magnet are arranged in sliding slot, slide along the chute；Magnetic detecting element is arranged in component accommodating cavity.
Preferably, reset spring is equipped between the sliding block and the end of sliding slot.
Preferably, in the state of force, sensor magnet is close to magnetic detecting element for the brake.
Preferably, the sensor magnet is magnet.
Preferably, the magnetic detecting element is tongue tube.
Be using the beneficial effect of above technical scheme: the power-off inductive switch of the utility model structure is small in size, stealthy
Below brake lever, driving is not stopped to use, and installed simply, reliable for operation, performance is stablized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of component accommodating cavity；
Fig. 3 is the structural schematic diagram of enclosure interior.
Wherein, 1-PCB plate, 2-- sensor magnet, 3-- magnetic detecting element, 4-- shell, 5-- brake handle, 6-- brake cable,
7-- sliding slot, 8-- component accommodating cavity, 9-- reset spring.
Specific embodiment
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1, Fig. 2 and Fig. 3 show specific embodiment of the present utility model: a kind of brake power-off inductive switch, including collection
At the controller, sensor magnet 2 and magnetic detecting element 3 in pcb board 1, magnetic detecting element 3 and controller electrical connection, sensor magnet 2
Under the action of brake cable 6, horizontal displacement is generated relative to magnetic detecting element 3.
Brake power-off inductive switch further includes shell 4, brake 5 and component accommodating cavity 8, and brake is cut with scissors relative to shell 4
It connects, component accommodating cavity 8 is located at the lower section of shell 4, and the edge of component accommodating cavity is equipped with positioning plate, passes through positioning plate and shell
It is mutually fixed；Brake is arranged in 5 end in the brake cable 6, and shell 4 is interior to be equipped with sliding slot 7, and sensor magnet 2 is arranged in sliding slot 7
Interior, 7 sliding along the chute is equipped with pulley at notch, and pulley plays the role of changing nyctitropic to brake cable, facilitates brake force；
Magnetic detecting element 3 is arranged in component accommodating cavity 8.
Reset spring 9 is equipped between sliding block and the end of sliding slot 7；Brake 5 in the state of force, sensor magnet 2 to
Magnetic detecting element 3 is close.
When pulling brake, brake cable is mobile, and brake cable moves in shell with the sensor magnet in movable slider, and setting exists
Magnetic detecting element and sensor magnet below shell generate change in location, and the variation of position leads to change of magnetic field strength, thus
So that magnetic detecting element output voltage is changed, which sends electric bicycle controller to by conducting wire, it is electronic from
Thermoacoustic prime engine device detects brake signal according to the variation of output voltage values, to realize brake power down function.
Sensor magnet is magnet；Magnetic detecting element is tongue tube；With brake cable band moving magnet, the not homopolarity of tongue tube is controlled
Reed on-off, the electrode at tongue tube both ends are drawn signal wire and are connected to controller.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
