Problems solved by technology
[0004] 1. The weakened rear fork is an additional object. In addition to additional mold opening and precision cutting, it must also be fixed to the frame, resulting in increased manufacturing costs. Moreover, once the rear fork is removed, the car will be damaged. unable to ride
[0005] 2. The deformation direction of the rear fork is the same as the direction in which the auxiliary motor pushes the wheel hub. The auxiliary motor will cause feedback when driving the wheel hub, which will distort the deformation signal of the rear fork. The auxiliary motor cannot provide correct power. The process is not natural and smooth
The measuring unit (70) disclosed in Fig.3A of U.S.PAT.7,814,800B2 is not consistent with the deformation direction of the rear fork (if correct, the measuring unit (70) should be configured on the leg of Fig.3A ( carrying leg62 surface), as a result, there will be inaccurate or even unmeasured situations.
[0007] Regarding the above-mentioned U.S.Pub.No. 2011 / 0040500A1, the two strain detectors (strainauge sensors 30a, 30b) shown in Fig. 8 are respectively installed on the opposite inner surfaces of the two rear hooks. The deformation direction of the claw when it is deformed by force is to deform towards the middle of the wheel shaft at the same time. Therefore, the deformation signals detected by the two strain detectors of this U.S.Pub.No. 2011 / 0040500A1 will cancel each other out of alignment, and, as Fig.2 shows the location of the strain detector (strain gauge sensor 30). When locking the axle, the strain detector (strain gauge sensor 30) is easily damaged by collision

Embodiment Construction
[0031] The invention is suitable for motor vehicles, such as electric bicycles or wheelchairs with auxiliary power. The moped is assisted by an auxiliary motor, which saves labor when riding the bicycle. The start-up and torsion of the auxiliary motor of the present invention are mainly due to a strain detector used to measure the strain of the object on a disposition position of the vehicle frame of the moped, and a driving force (such as stepping on a bicycle pedal) of a human operation is used. Pedal force), causing the configuration position of the motor vehicle frame and the strain detector to deform, so that the strain detector detects a deformation signal, and controls an auxiliary motor according to the magnitude of the deformation signal to provide a The amount of deformation is proportional to the power assist, the greater the driving force, the greater the deformation signal, and the greater the power assist provided by the auxiliary motor.

Provided are a configuration method and device for strain sheet detectors. The number of the strain sheet detectors is at least two, and the strain sheet detectors are configured to two side faces, with different deformation amounts, of a configuration position of a moped correspondingly according to the configuration method. The configuration method needs to include the following conditions that 1, when thrust-tensile force is applied to the moped manually, the configuration position deforms, and the acting force of deformation is in direct proportion to the thrust-tensile force; 2, while the thrust-tensile force is applied to the moped, the deformation direction of the configuration position of the strain sheet detectors is independent of the moving direction of the thrust-tensile force; and 3, the strain detection direction of the strain sheet detectors is identical with the deformation direction of the configuration position. Thus, the tensile force data or thrust force data can be measured accurately, and the situation that a feedback signal is generated to the strain sheet detectors when an auxiliary motor operates is avoided.
Description
【Technical field】 [0001] The present invention relates to a configuration method and device of a strain gauge detector that utilizes a strain gauge detector that generates deformation signals caused by push and pull forces; in particular, it relates to a strain gauge detector that can accurately measure pull or push force data without causing auxiliary When the motor is running, a feedback signal is generated to provide correct auxiliary power to the moped, so that the moped can ride more naturally. 【Background technique】 [0002] An electric bicycle is a bicycle with an electric auxiliary motor. The user drives the bicycle by applying pedal force. The auxiliary power applied by the auxiliary motor is proportional to the user's pedal force, that is, the pedal force (that is, the push The greater the force, the greater the auxiliary power of the auxiliary motor. Known technology for measuring the size of the pedal force, among them, WO2001030643 A1 case, the case is mainly t...
