Description

Adjustable belt switch brake crank

Technical field

The utility model relates to the parts of Electrical Bicycle, specifically a kind of brake crank for the band magnetic induction switch that brakes.

Background technology

Electrical Bicycle is the huge traffic of whole world owning amount, rides instead of walk and fitness tool, and in order to regulate gait of march and braking, the belt switch brake crank is indispensable parts.The induction type belt switch brake crank of present widely used Electrical Bicycle lacks accurate adjustability.China utility application number 201220081342.7 Granted publication CN202624548U, name is called: the patent of the adjustable electrical induction structure that the brake handgrip starts, provided a kind of comparatively accurate adjustable belt switch brake crank, and begun to produce and come into the market.This patent not enough as follows: one, because the adjusting direction of the sensor of this scheme is straight line, and the path of motion of the magnetic substance on the handle is not complete straight line, and both are difficult to agree with fully, and it is accurate inadequately to adjust precision.Two, magnetic substance and sensor have the magnetic substance of rotation and sensor just to leave big distance too away from bracket cup slightly, cause the service area of switch less than normal, can produce brake under the extreme case and pull on earth, and motor is activated again on the contrary, easily causes dangerous by bike.Three, done the wrap of sensor with aluminum alloy, volume increases, and weight increases.

The utility model content

Defective at above-mentioned prior art existence, the purpose of the adjustable belt switch brake crank of the utility model is: not only be to provide a kind of comparatively accurate adjustable belt switch brake crank, and the service area of switch is greatly increased, and comparatively micro-miniaturisation and lightweight.

Realize that the technical solution of the utility model is such: a kind of adjustable belt switch brake crank, comprise handle, handle seat, sensor module, permanent magnet, bracket cup, clamp nut and governing screw, it is characterized in that: described handle and sensor module are the axle center rotation with the axis of bracket cup all, inlay on the handle or be pasted with permanent magnet, have on the described sensor module to supply the adjusting deep-slotted chip breaker of regulating and dry-reed tube is housed, described handle seat has the little screw corresponding with governing screw.The middle part of the position of the permanent magnet on the described handle between axle center hole and mounting hole is to the zone near axle center hole.Be that axis with bracket cup is the arc groove in axle center for the adjusting deep-slotted chip breaker shape of regulating on the described sensor module, in order to ensure with the coaxial rotation of handle, sensor module is enclosed within on the clamp nut or rotates along the arc convex tendon on the handle seat with arc groove.The arc convex tendon of described handle seat is that the axis with bracket cup is the circular arc muscle in axle center.In the technical solution of the utility model, guaranteed that permanent magnet and the dry-reed tube on the sensor module on the handle all rotating around same axle center, both relative positions just are easy to adjust, and mix up the back and with governing screw sensor module are fixed on the handle seat.The position of permanent magnet has guaranteed that near the zone of axle center hole the service area of switch greatly increases.

The beneficial effects of the utility model are that with respect to the adjustable belt switch brake crank of present use, the utility model adjustment is got up more accurate, and the service area of switch is greatly increased, increase about 20%, and comparatively micro-miniaturisation and lightweight, the corresponding raw MAT'L that reduced weight savings.

The specific embodiment

The utility model is described in further detail below in conjunction with implementing.

Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Figure 14, it is a specific embodiment of the adjustable belt switch brake crank of the utility model, the adjustment of sensed position once at first is described: handle 1 is installed in the handle seat 2 by bracket cup 5, clamp nut 6 is tightened bracket cup 5, handle 1 can be around the axis rotation of bracket cup 5, permanent magnet 8 on the handle 1 equally can be around the axis rotation of bracket cup 5 along with handle 1, and the path of motion of permanent magnet 8 is circular arcs; Sensor module 3 is to be enclosed within on the clamp nut 6, can be around the axis rotation of clamp nut 6 and bracket cup 5, sensor module 3 has for the adjusting deep-slotted chip breaker of regulating 11 and dry-reed tube 9 is housed, the path of motion of dry-reed tube 9 also is a circular arc, permanent magnet 8 and dry-reed tube 9 are around the circular motion of same axle center, the relative position adjustment of the two just easily, people can find best sensed position accurately by rotation sensor assembly 3, screw governing screw 7 then, sensor module 3 is fixed on the handle seat 2, the little screw 4 of a correspondence is arranged on the handle seat 2; Be that axis with bracket cup 5 is the arc groove in axle center for adjusting deep-slotted chip breaker 11 shapes of regulating on the sensor module 3.Next illustrates working process, and when quiescence, permanent magnet 8 and dry-reed tube 9 are in a non-induction zone, and this non-induction zone is the middle part that permanent magnet 8 is in dry-reed tube 9, if dry-reed tube 9 is often opened, dry-reed tube 9 is exactly the state of often opening so; Handle 1 rotational angle strengthens, and has arrived induction zone, and dry-reed tube 9 just enters closed state, until handle 1 turns to end position, and the state that dry-reed tube 9 just remains closed always.

Fig. 5, Fig. 6 and Figure 10 are second kind of specific embodiment of the present utility model, what Fig. 5 was shown in Figure 6 is the distortion money of the band through hole of sensor module 3, circular hole and cheese head screw 10 that bracket cup 5 passes the distortion money screw, purpose is to increase the sensor module constant intensity, is with previous just the same on the principle.

Fig. 7, Fig. 8, Fig. 9, Figure 11 and Figure 12 are front elevation and the block diagrams of the another kind distortion money of sensor module 3 of the present utility model, with and principle of work, the another kind distortion money of sensor module 3 has arc groove 12, rotate along the arc convex tendon 13 that increases at handle seat 2 with arc groove 12, the arc convex tendon 13 of described handle seat is that the axis with bracket cup 5 is the circular arc muscle in axle center.

Figure 13 clearly illustrates the position of permanent magnet 8, and the middle part of the position of the permanent magnet 8 on the handle 1 between axle center hole 15 and mounting hole 14 is to the zone near axle center hole 15.The position of permanent magnet 8 can not be away from axle center hole 15, if the position of permanent magnet 8 is away from axle center hole 15, be positioned near the mounting hole 14, handle 1 has rotation slightly so, permanent magnet 8 and dry-reed tube 9 just leave big distance, cause the service area of switch less than normal, can produce brake under the extreme case and pull on earth, motor starts again on the contrary, easily causes dangerous by bike.

Other magnetic induction electronic elements such as Hall element are replaced dry-reed tube 9, and above principle and structure are suitable equally.

The shell of sensor module 3 is by non-armoured magnetic field or to the little material manufacturing of former Distribution of Magnetic Field influence.
