Abstract
The utility model discloses a non-contact-type torque sensor for a middle shaft of an electric bicycle. The non-contact-type torque sensor for the middle shaft of the electric bicycle comprises a middle shaft shell and a middle shaft arranged in the middle shaft sleeve in a rotating mode. A fixing sleeve is fixedly connected to one end of the middle shaft, and a sliding sleeve is connected to a position, close to the fixing sleeve, on the middle shaft in a sliding mode. A first inclined surface is arranged at one end of the fixing sleeve and is matched with a second inclined surface at one end of the sliding sleeve, and an annular pressure spring is arranged at the other end of the sliding sleeve. One end of the annular pressure spring abuts against the middle shaft, and the other end of the annular pressure spring abuts against the sliding sleeve. A magnetic ring is arranged on the sliding sleeve, and a displacement sensor is arranged on the outer side of the sliding sleeve. The non-contact-type torque sensor for the middle shaft of the electric bicycle is arranged in the middle shaft shell in an airtight mode, is easy to disassemble and assemble and convenient to maintain, and effectively prevents external factors like mechanical collision from affecting a sensing system. Furthermore, displacement is converted to electric signals through the magnetic ring and the displacement sensor, the electric signals are transmitted to the controller, and therefore torque is determined, non-contact-type measurement is achieved, and service life of the whole device is effectively prolonged.
Description
Technical field
The utility model relates to a kind of electrical bicycle middle shaft non-contact torque sensor.
Background technology
Electrical Bicycle refers to storage battery on the basis of ordinary bicycle, the Personal Transporter of the electromechanical integration of the control member such as motor, controller, storage battery, handle brake lever and display instrument system to be installed as auxiliary energy.Existing Electrical Bicycle is meeting mounting torque sensor on axis usually, thereby so that the user of Electrical Bicycle when foot-operated riding, adjusts the output power of motor of Electrical Bicycle according to measured moment of torsion.Yet, the torque sensor that existing electrical bicycle middle shaft adopts, complex structure, service life is short, and installs loaded down with trivial detailsly, safeguards inconvenience.
The utility model content
The purpose of this utility model is for the problems referred to above, a kind of electrical bicycle middle shaft non-contact torque sensor is provided, the torque sensor complex structure that adopts to solve existing electrical bicycle middle shaft, service life is short, install loaded down with trivial detailsly, safeguard the problem of inconvenience.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of electrical bicycle middle shaft non-contact torque sensor, comprise that intermediate axle housing and rotation are arranged on the axis in the intermediate axle housing, one end of described axis is fixedly connected with fixed cover, and next-door neighbour's fixed cover place slidely connects sliding sleeve on the axis, described fixed cover is provided with the first inclined-plane near an end of sliding sleeve, described the first inclined-plane matches with second inclined-plane of sliding sleeve near fixed cover one end, the other end of described sliding sleeve is provided with annular stage clip, one end of described annular stage clip is resisted against on the axis, its other end is resisted against on the sliding sleeve, be provided with magnet ring on the described sliding sleeve, and the arranged outside of sliding sleeve there is the displacement pickup that is electrically connected with the controller of Electrical Bicycle.
Further, be provided with feather key on the described axis, have the chute that matches with feather key on the described sliding sleeve.
Further, the left end of described intermediate axle housing is fixedly connected with left axle bowl, and its right-hand member is fixedly connected with right axle bowl, is provided with the left bearing that matches with axis in the described left axle bowl, is provided with the right bearing that matches with axis in the described right axle bowl.
The beneficial effects of the utility model are, described electrical bicycle middle shaft is enclosed within the intermediate axle housing with non-contact torque sensor, volume is little, be easy to assembling and dismounting, easy to maintenance, and actv. has prevented the impact of the external factors such as mechanical collision on sensor-based system, in addition, it changes the displacement of sliding sleeve electric signal into and transfers to controller by magnet ring, displacement pickup, thereby determine torque, realized non-contact measurement, Effective Raise the service life of whole device, simple in structure, be easy to realize.
Description of drawings
Fig. 1 is the structural representation that the utility model electrical bicycle middle shaft is used non-contact torque sensor.
Among the figure:
1, intermediate axle housing; 2, axis; 3, left axle bowl; 4, left bearing; 5, displacement pickup; 6, sliding sleeve; 7, fixed cover; 8, right bearing; 9, right axle bowl; 10, annular stage clip; 11, magnet ring.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to shown in Figure 1ly, Fig. 1 is the utility model electrical bicycle middle shaft with the structural representation of non-contact torque sensor; In present embodiment, a kind of electrical bicycle middle shaft non-contact torque sensor, comprise intermediate axle housing 1 and rotate the axis 2 that is arranged in the intermediate axle housing 1, the left end of described intermediate axle housing 1 is fixedly connected with left axle bowl 3, its right-hand member is fixedly connected with right axle bowl 9, described left axle bowl 3 is connected with axis 2 by left bearing 4, described right axle bowl 9 is connected with axis 2 by right bearing 8, one end of described axis 2 is fixedly connected with fixed cover 7, and be provided with feather key on the axis 2, have the chute that matches with feather key on the described sliding sleeve 6, described fixed cover 7 is provided with the first inclined-plane near an end of sliding sleeve 6, described the first inclined-plane matches with second inclined-plane of sliding sleeve 6 near fixed cover 7 one ends, the other end of described sliding sleeve 6 is provided with annular stage clip 10, one end of described annular stage clip 10 is resisted against on the axis 2, its other end is resisted against on the sliding sleeve 6, sliding sleeve 6 is under the effect of annular stage clip 10, so that the second inclined-plane of the first inclined-plane of sliding sleeve 6 and fixed cover 7 is close to, be provided with magnet ring 11 on the described sliding sleeve 6, and the arranged outside of sliding sleeve 6 there is the displacement pickup 5 that is electrically connected with the controller of Electrical Bicycle.
During work, sliding sleeve 6 is close to fixed cover 7 under the effect of annular stage clip 10, when Electrical Bicycle meets obstructions, corresponding sprocket wheel is subject to resistance, thereby so that the fitting surface between sliding sleeve 6 and the fixed cover 7 pushes mutually, sliding sleeve 6 produces longitudinal travel after the extruding, and this displacement is converted to electric signal through magnet ring 11, displacement pickup 5, and with the controller of electric signal transmission to Electrical Bicycle, thereby the sensing of realization moment.
Above embodiment has just set forth groundwork of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
