First Claim
1. An installation method comprising:
- providing an electrical vehicle including a frame, an axle fixed to the frame in a non-movable manner relative to the frame, a hub rotatable on the axle, a pedal rotatably mounted to the frame, and a driving chain extending between the pedal and the hub; and
installing a strain gauge sensor at an installation location on the frame spaced from the axle and the pedal, with the strain gauge sensor generating a deformation signal measuring a pushing/pulling force applied by the driving chain, with the installation location of the strain gauge sensor satisfying the following methods;
Method 1;
when the pushing/pulling force is applied by the pedal to the installation location of an electrical vehicle, the installation location is deformable and a deforming action force is directly proportional to the pushing/pulling force;
Method 2;
when the pushing/pulling force is applied, the vehicle deforming direction at the installation location is independent to a pushing/pulling force moving direction; and
Method 3;
a strain detecting direction of the strain gauge sensor is in a same direction as a vehicle deforming direction at the installation location.

Abstract
An installation method and an apparatus of a strain gauge sensor are capable of driving an object to be measured to generate a deformation signal by a pushing/pulling force. At least two strain gauge sensors are installed on surfaces with different amounts of deformation and at an installation location of an electrical vehicle according to the installation method. The installation method includes Method 1: When a manual pushing/pulling force is applied, the installation location is deformed and the deforming action force is directly proportional to the pushing/pulling force. Method 2: When the pushing/pulling force is applied, the vehicle deforming direction at the installation location is independent to the pushing/pulling force moving direction. Method 3: The strain detecting direction of the strain gauge sensor is the same as the vehicle deforming direction at the installation location. Therefore, pulling or driving force data can be measured accurately.
