Problems solved by technology

[0002] The disk of the traditional electric vehicle sensor is installed on the center shaft of the bottom bracket, which can easily cause the instability of the sensing signal during use; in addition, the disk of the sensor will cause the distance (CHAINLINE) from the center of the car body to the center plate to be biased. Large, affecting speed change;
[0003] The traditional two-piece and three-piece variable speed chainring does not have a guard plate, and the chain is easy to fall inward, which brings discomfort to the electric bicycle

Embodiment

[0013] Embodiment: An electric bicycle sensor installation structure, based on the direction of use, the electric bicycle is located at the inner side of the inner chain wheel 1 and is fixed with an inner chain cover 2, and the inner chain cover 2 is provided with a magnetic steel head mounting hole 3, and the electric bicycle The magnetic steel head of the bicycle sensor can be fixedly inserted in the magnetic steel head mounting hole. When in use, the magnetic steel head 5 of the sensor is directly fixed in the magnetic steel head mounting hole 3 of the inner chain cover 2. The sensor is easy to install and stable. , is not easy to fall off, and the sensor signal is stable. Since there is no need to use a disk to install the sensor, it saves the space for installing the disk on the bottom bracket 4, and effectively reduces the distance from the center of the car body to the center disk, making the electric bicycle shift Sensitive, the inner chain cover also acts as a stop for...

Abstract

The invention discloses an installation structure of an electric bicycle sensor. By taking the using direction as reference, the inner side of an inner chain wheel of an electric bicycle is fixedly provided with an inner chain cover; the inner chain cover is provided with a magnetic-steel head installing hole; and a magnetic-steel head of the electric bicycle sensor can be fixedly inserted in the magnetic-steel installing hole rightly. The sensor is installed on the inner chain cover, so that the signal of the sensor is stable; simultaneously the distance from the center of the bicycle body to a central disc is effectively reduced, so that the speed of the electric bicycle can be changed flexibly; and meanwhile, the inner chain cover plays a role of backstopping a chain, thus preventing the chain from falling down inwards.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to a sensor installation structure of the electric bicycle. Background technique [0002] The disk of the traditional electric vehicle sensor is installed on the center shaft of the bottom bracket, which can easily cause the instability of the sensing signal during use; in addition, the disk of the sensor will cause the distance (CHAINLINE) from the center of the car body to the center plate to be biased. Large, affecting speed change; [0003] The traditional two-piece and three-piece variable speed chainrings do not have a guard plate, and the chain is easy to drop inward, which brings discomfort to the electric bicycle. Contents of the invention [0004] In order to make up for the above deficiencies, the present invention provides a sensor installation structure for an electric bicycle. The sensor installation structure for an electric bicycle makes the sensor signal stable, and the ele...
