Problems solved by technology

However, opening the installation groove on the crank and the installation groove on the sprocket connection plate are the same, and the torque sensor and the microprocessor chip are integrated on the crank or the sprocket connection plate. If there is a failure, only the crank and sprocket can be replaced. The connecting plate is expensive to use and replace, and it is inconvenient to repair and maintain

Embodiment Construction

[0025] Such as figure 1 Shown is a bicycle power measuring device disclosed in the present invention, including a torque sensor 10 and a micro-processing chip (common components, not shown in the figure).

[0026] A shaft sleeve 11 is formed by extending the fixed end of the crank 1 and the central shaft 2, and the shaft sleeve 11 is sleeved on the central shaft 2, and there is a gap between the shaft sleeve 11 and the central shaft 2, so that the shaft sleeve 11 and the central shaft 2 can be formed. twist.

[0027] The shaft sleeve 11 is provided with a mounting position 12 . The installation position 12 can be a groove directly formed on the shaft sleeve 11, or as shown in the figure, the sprocket connection plate 3 can be installed on the shaft sleeve 11, and a gap is left between the sprocket connection plate 3 and the shaft sleeve 11 to form the installation position 12.

[0028] The torque sensor 10 is fixed on the installation position 12, which eliminates the restr...

Abstract

The invention discloses a measuring device for power of a bicycle. The measuring device for the power of the bicycle comprises torsion sensors and a microprocessor chip, wherein one end, fixed to a middle shaft, of a crank extends to form a shaft sleeve, the middle shaft is sleeved with the shaft sleeve, a gap is reserved between the shaft sleeve and the middle shaft, installing positions are arranged on the shaft sleeve, the torsion sensors are fixed to the installing positions, and are connected with the microprocessor chip, the number of the installing positions is four, each torsion sensor is fixed to each installing position, the four torsion sensors are connected in series to form a Wheatstone bridge, the Wheatstone bridge is connected with the microprocessor chip, and the torsion sensors and the microprocessor chip are arranged in a separated mode. The measuring device for the power of the bicycle is convenient to install, maintain and replace, more stable in signal sensing, and more accurate in measurement, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a bicycle power measuring device. Background technique [0002] In the prior art, the installation structure of the power measuring device on the bicycle is generally as follows: an installation slot is opened on the sprocket connecting plate (also known as the spider frame) of the bicycle, and the torque sensor and the micro-processing chip of the power measuring device are directly installed on the bicycle. In the installation groove of the sprocket connection plate, the microprocessing chip obtains the riding torque information from the torque sensor and performs data processing, and then transmits the power signal to the display device for display, thereby measuring the bicycle riding power. This structure will limit the installation space of the sprocket connection plate because an installation groove will be opened on the sprocket connection plate, and only 2 sprockets can...
