Abstract

The invention provides a pressure measuring device and a bicycle stepping sensor. The pressure measuring device comprises a bearing, an elastic member, a pad and a force sensor. The elastic member isinternally provided with a cushion block, and gaps are arranged at two sides of contacts or contact lines between the cushion block and the elastic member; the elastic member and the cushion block constitute a bearing mounting position, the bearing is disposed in the elastic member, and the force sensor is disposed on the outer side of the elastic member. The invention attaches the sensor on the elastic member and measures the pulling force by using the indirect measurement method, and has the advantages of simple structure and low cost; by setting the sensor on a fixed component, the normal operation of the device is not affected, and the accurate measurement value can be ensured at the same time; by setting the cushion block and the gaps for the cushion block, the normal deformation of the elastic member is ensured and the deformation quantity of the elastic member is protected, and the sensitivity is maintained.

Description

technical field [0001] The invention belongs to the field of sensors, in particular to a pressure measuring device and a bicycle pedaling sensor. Background technique [0002] The pressure sensor is one of the most commonly used sensors. According to the principle, it can be divided into strain gauge type and spring type. However, the existing pressure sensors usually require the measured object to be relatively fixed with the sensor. For example, the contact of the strain gauge needs to be connected by wires. When the shaft rotates, it is usually impossible to use or use a slip ring for connection. But at this time, the life of the sensor will be affected by the construction of the slip ring, and the reliability is not Good, there is a lack of a pressure sensor suitable for running or moving situations. Contents of the invention [0003] In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a pressure measuring device, by...
