Embodiment
Embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, shaft type moment sensor behind a kind of intelligent electric bicycle, this device comprises installing plate 1, the outside of installing plate 1 is outward extended with installation sleeve 2, the slotted hole 3 that the center of installing plate 1 and installation sleeve 2 is through with, slotted hole 3 horizontal directions are arranged, the both sides up and down of the inner cylindrical of installation sleeve 2 are equipped with draw-in groove 4, installation sleeve 2 can be embedded in the pickup groove 6 on the vehicle frame back axle sheet (hook) 5, the outer end cylindrical of installation sleeve 2 is provided with screw thread and is spirally connected with nut 7, when nut 7 is also tight, installing plate 1, installation sleeve 2 is fixing with vehicle frame back axle sheet (hook) 5, be inserted with off-axis cover 8 in the slotted hole 3, off-axis cover 8 is provided with the off-axis hole 11 of rear axle 10 insertions of power supply runner hub 9, the outer end of off-axis cover 8 is offset flat shape and is inserted in the slotted hole 3, the cylindrical of the inner of off-axis cover 8 is rounded, be provided with support chip 12 between installing plate 1 and the off-axis cover 8, support chip 12 is provided with circular hole 15, circular hole 15 is enclosed within off-axis and overlaps on the cylindrical of 8 the inners, be provided with screw pin 16 between the bottom of support chip 12 and the installing plate 1, make support chip 12 off-axis can be overlapped 8 and slightly upwards lift, contact with the bottom surface of slotted hole 3 with the bottom of avoiding rear axle 10.
Be embedded with on the described support chip 12 on magnet steel 13, the installing plate 1 and be embedded with Hall element 14, and the corresponding installation with the position of Hall element 14 of magnet steel 13.
Be connected with arc-shaped spring piece 17 between described support chip 12 and the installing plate 1, make off-axis cover 8 have all the time backward trend.
After the utility model is installed on the electric bicycle, installing plate 1, installation sleeve 2 are fixed with vehicle frame back axle sheet (hook) 5, and off-axis cover 8 is fixing with rear axle 10, and because the supporting role of support chip 12, in fact off-axis cover 8 is unsettled in slotted hole 3, just under the effect of arc-shaped spring piece 17, support chip 12, off-axis cover 8, rear axle 10 have all the time trend backward.
When the step of cyclist's pedal, chain wheel drives chain, chain drives wheel hub, electric bicycle is travelled forward, and the effect that the tension force of chain makes support chip 12, off-axis cover 8, rear axle 10 overcome arc-shaped spring piece 17 together moves forward, at this moment will produce induced signal between magnet steel 13 and the Hall element 14, this induced signal is imported in the controller to be handled, and controller will be regulated the size of output current or voltage, thereby reaches the effect of intelligent power-assisted.
Because the pickup groove 6 on the electric bicycle vehicle frame back axle sheet (hook) 5 also not all is a horizontal direction setting, so installing plate 1 of the present utility model is provided with a plurality of pin joints hole 18, a plurality of pin joints hole 18 is positioned on the circumference of same radius, adjust pin joint for support chip 12, to guarantee that support chip 12 can overlap off-axis 8 and slightly upwards lift, to avoid rear axle 10 to contact with the bottom surface of slotted hole 3, reduce friction with the bottom of off-axis cover 8.
Because the utility model needs support chip that off-axis cover 8 and rear axle 10 are slightly upwards lifted, when so off-axis cover 8 and rear axle 10 move forward and backward, it is the circular arc in the center of circle that its track is actually with screw pin 16, but, because the distance that off-axis cover 8 and rear axle 10 move forward and backward is very little, so can think straight line approx.
Though off-axis cover 8 of the present utility model is vacant state in the slotted hole 3 of installing plate 1, but in fact the gap between off-axis cover 8 and the slotted hole 3 is very little, because the susceptibility of present Hall element 14 is very high, and signal amplification circuit, and the micro-displacement between the magnet steel 13 in addition can produce signal and be input in the controller.
The domestic electric bicycle market brand of China is many, kind assorted, and the utility model biggest advantage is exactly to carry out supporting installation for all in the market electric bicycles, and need not electric bicycle is changed during supporting installation.
