Embodiment Construction
[0024] The present invention will be further described below in conjunction with the drawings.
[0025] Such as figure 1 As shown, a torque sensor for an electric bicycle includes a central shaft 1, a torque ring 12, and a sensing mechanism 4. The torque ring 12 includes an inner ring 2 and an outer ring 3, and the sensing mechanism 4 is arranged in the inner ring 2 and the outer ring 3, the inner ring 2 is provided with a trigger block 5 capable of resisting the sensing mechanism 4. When the central shaft 1 drives the inner ring 2 to rotate, the trigger block 5 activates the sensing mechanism 4, the inner ring 2 and the outer ring A number of deformation mechanisms 7 that can make the torque ring 12 rebound are provided in the circumferential direction between 3.
[0026] Preferably, the moment ring 12 further includes a limiting block 6 provided on the inner ring 2 and a protrusion 11 provided on the outer ring 3 and capable of abutting against the limiting block 6.
[0027] The t...

The invention discloses an electric booster vehicle torque sensor. The technical scheme of the invention is as follows: A torque sensor for an electric booster vehicle includes the central axis, a torque ring and an induction mechanism, the torque ring includes an inner ring and an outer ring, The induction mechanism is arranged between an inner ring and an outer ring, a trigger block capable of resisting the induction mechanism is arranged on the inner ring, the induction mechanism is activated by the trigger block when the middle shaft drives the inner ring to rotate, and a plurality of deformation mechanisms capable of making the torque ring rebound are arranged between the inner ring and the outer ring in the circumferential direction. The scheme provided by the invention can still work normally when the torque is large, the service life of the torque sensor is prolonged, the deformation mechanism is an elastic structure, the rigidity of the torque sensor is ensured, the spring-back effect of the torque sensor is ensured to the maximum extent, the auxiliary force attenuation is reduced, and the problems of continuous power supply and stress concentration of the torque sensor battery are solved.
Description
Technical field [0001] The present invention relates to the technical field of torque sensors, and in particular to a torque sensor for electric assisted vehicles. Background technique [0002] As people's awareness of environmental protection and health has gradually increased, bicycles have re-entered the public's vision as an environmentally friendly and convenient short-distance transportation tool and have become a unique landscape that can be seen everywhere in the city. In recent years, compared with traditional bicycles, electric-assisted bicycles have won more and more people's favor in the field of bicycles due to their labor-saving and energy-saving characteristics. For a good electric-assisted bicycle, the internal core component-the torque sensor is the key to determining its performance. [0003] The torque sensor equipped on the electric assist bicycle in the prior art senses the torsional strain of the bicycle's center axle when the rider steps on it by receiving t...
