Abstract
The utility model discloses a stepless speed regulator for the speed regulation of an electric bicycle. The utility model is characterized in that a handle is composed of a fixed handle seat and a rotary handle; firstly, a linear hall sensor is fixed on the fixed handle seat, and secondly, two small corresponding permanent magnets are fixed on the rotary handle, and the two small permanent magnets are respectively arranged on the left and the right sides of the linear hall sensor. The speed regulator has the advantages of simple structure, reliable work, long service life and low power consumption, being an ideal stepless speed regulator for an electric bicycle.
Description
The utility model relates to a kind of continuous speed regulation system of Electrical Bicycle.
The governor of Electrical Bicycle all is mounted on the handgrip of Electrical Bicycle, reaches the speed change of Electrical Bicycle by the left-right rotation of handle.Used governor has potential device speed governing and photoelectricity speed governing dual mode at present.Wherein the potential device speed governing is that potential device is installed on the handgrip, changes the resistance size of potential device by the left-right rotation of handle, thereby the speed adjusting resistance that is connected in series in the armature circuit of DC machine is changed, and reaches the speed governing of motor.And the electro-optical tubes speed governing is to rotate by handle to affect moving of a steel wire, thereby the anti-dazzle device that links to each other with the steel wire other end is moved, change the break-make number of elements of a series of electro-optical tubess, and then change that speed adjusting resistance changes in the armature circuit of DC machine, reach the purpose of electric machine speed regulation.Because potential device is easy to generate wearing and tearing, and steel wire ruptures easily, so the reliability of these two kinds of mode of speed control is relatively poor, service life is not long.All be in armature circuit, to have sealed in speed change resistance owing to these two kinds of mode of speed control again, so their consumed powers are bigger.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of simple in structure, easy to use, and good reliability does not have wearing and tearing, long service life, the stepless speed adjusting gear that consumption of power is low.
The purpose of this utility model reaches by following measure.The handgrip of this stepless speed adjusting gear also is made of seat and swing handle fixing.Swing handle is to be enclosed within fixing the outside of seat, and can rotate seat around fixing.Wherein on fixing the external cylindrical surface of seat, a small boss is arranged, and on this small boss, fixing a linear hall sensor.The small boss that 80 ° each other～150 ° of two angles are arranged on the external cylindrical surface of swing handle inner core in addition, and on these two small boss, be fixed with a little permanent magnet respectively.And these two little permanent magnets must be in the same plane with linear hall sensor, and lay respectively at the and arranged on left and right sides of linear hall sensor.
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with embodiment: this Electrical Bicycle stepless speed adjusting gear is fixing seat (1), swing handle (2), linear hall sensor (4) and permanent magnet (3) to be made of.Wherein linear hall sensor (4) is to be fixed on fixing the small boss on the external cylindrical surface of seat (1).And two permanent magnets (3) are to be separately fixed on the external cylindrical surface of swing handle (2) inner core, and its angle is mutually on two small boss of 100 °.The swing handle (2) that permanent magnet (3) will be housed then is sleeved on the fixing the outside of seat (1) of Hall element (4) is housed, and swing handle (2) can be rotated seat (1) around fixing.Also must make simultaneously to fix Hall element (4) on the seat (1) and two the little permanent magnets (3) on the swing handle (2) are in the same plane, and these two little permanent magnets (3) lay respectively at the and arranged on left and right sides of linear hall sensor (4).
When this governor uses, only need the swing handle left-right rotation will be caused the change of permanent magnet to the magnetic induction density of linear hall sensor.Again because the output voltage of linear hall sensor and its outer magnetic induction density are the linear changing relation.So as long as in a single day the outer magnetic induction density of linear hall sensor change, then the output voltage of linear hall sensor also changes thereupon, the voltage that is added to like this on the DC machine also changes thereupon, thereby reaches the purpose of DC motor speed-regulating.
The utility model has following advantage compared to existing technology: this governor structure is simple, and is easy to operate, the worker Do very reliable, long service life, power consumption is low, is a kind of desirable stepless speed regulator for electric bicycle.
