Summary of the invention
The purpose of this utility model provides a kind of battery-operated motor cycle/bicycle brake handlebar with sensing device, it can in time be delivered to controller with brake signal at glancing impact, make controller to the instruction that motor sends appropriate outage or reduction horsepower output, guarantee vehicle and personal safety.
A kind of battery-operated motor cycle/bicycle brake handlebar described in the utility model with sensing device, comprise handlebar grip, brake handle, brake handle is hinged by bolt and handlebar grip, on bolt, be provided with torsion spring, one end of torsion spring is fixed on the handlebar grip, the other end is fixed on the brake handle, it is characterized in that: brake handle and handlebar grip pin jointed end are a cam, on handlebar grip, be provided with a sensing device, the overcoat of this sensing device is fixedly connected on the handlebar grip, one end of overcoat is provided with the first linear Hall unit, the first linear Hall unit connects with controller by lead, the other end of overcoat is provided with magnet steel seat and magnet steel, and magnet steel is corresponding with the first linear Hall unit; Between the step of end of magnet steel seat and overcoat one end, be provided with compression spring, the cam of the other end of magnet steel seat and brake handle one end near.
Described a kind of battery-operated motor cycle/bicycle brake handlebar with sensing device is provided with brake steel cable guide groove at handlebar grip, is provided with brake steel cable knock hole at brake handle.
During brake, rotate brake handle, the cam rotation, magnet steel seat moves to the length of spring compressed direction under cam rotation, and Hall element output dynamic voltage signal passes to ECU, the power on/off time of control motor, the safety hazard of the artificial brake of minimizing.
A kind of battery-operated motor cycle/bicycle brake handlebar described in the utility model with sensing device, comprise handlebar grip, brake handle, brake handle is hinged by bolt and handlebar grip, on bolt, be provided with torsion spring, one end of torsion spring is fixed on the handlebar grip, the other end is fixed on the brake handle, it is characterized in that: on handlebar grip, be provided with a sensing device, the overcoat of this sensing device is fixedly connected on the handlebar grip, one end of overcoat is provided with the second linear Hall unit, and the second linear Hall unit connects with controller by lead; Pin jointed end at brake handle and handlebar grip is provided with annular magnetic steel, and annular magnetic steel is corresponding with the second linear Hall unit.
Described a kind of battery-operated motor cycle/bicycle brake handlebar with sensing device is provided with brake steel cable guide groove at handlebar grip, is provided with brake steel cable knock hole at brake handle.
During brake, rotate brake handle, the annular magnetic steel rotation, Hall element output dynamic voltage signal passes to ECU, the power on/off time of control motor, the safety hazard of the artificial brake of minimizing.
The utility model is compared with prior art and is had the following advantages: owing to adopt the cam displacement mechanism, the linear voltage of output can make controller judge the speed of brake speed, dynamic torque and speed signal in conjunction with transmission sensors, and the angular signal of rotation direction sensor, the Based Intelligent Control motor turns over before when reducing emergency brake and the rollover situation when turning takes place; An on-off signal is just exported in traditional brake, and controller can't be judged the brake intention of chaufeur, and function is simple relatively; Simple and reliable for structure, cost is compared increase seldom with traditional brake handle.
The specific embodiment
Embodiment one: first scheme of the present utility model.
Referring to Fig. 1 and Fig. 2, brake handle 2 is hinged with the handlebar grip 1 that is provided with brake steel cable guide groove 10 by bolt 3 for the end of cam 2-1, torsion spring is installed 4 on bolt 3, and make an end of torsion spring be fixed on the handlebar grip, the other end is fixed on the brake handle; Brake handle 2 is provided with brake steel cable knock hole 2-2, so that the brake steel cable is installed; The overcoat 5 of sensing device is fixedly connected on the handlebar grip, and the first linear Hall unit 6 is installed an end of overcoat, and the first linear Hall unit connects with controller by lead; Magnet steel seat 7 and magnet steel 8 are installed in the other end of overcoat, and magnet steel is corresponding with the first linear Hall unit; Compression spring 9 is installed between the step of end of magnet steel seat and overcoat one end, and the cam 2-1 that makes the other end of magnet steel seat and brake handle one end is near getting final product.
Embodiment two: alternative plan of the present utility model.
Referring to Fig. 3 and Fig. 4, the brake handle 12 that is provided with brake steel cable knock hole 19 is hinged with the handlebar grip 11 that is provided with brake steel cable guide groove 18 by bolt 13, torsion spring 14 is installed on the bolt 13, and an end of torsion spring is fixed on the handlebar grip, the other end is fixed on the brake handle; The overcoat 15 of sensing device is fixedly connected on the handlebar grip 11, and the second linear Hall unit 16 is installed in an end of overcoat, and the second linear Hall unit connects with controller by lead; Annular magnetic steel 17 is installed in the pin jointed end of brake handle and handlebar grip, and makes the annular magnetic steel and second linear Hall unit 16 corresponding the getting final product.
