Description

Technical Field

[0001] The utility model relates to the field of bicycle power-assist sensors, in particular to a power-assist sensor which is easy to install. Background Art

[0002] A power-assisted bicycle is a new type of two-wheeled vehicle, a type of bicycle. It uses a battery as an auxiliary power source, is equipped with a motor, and has a power-assist system. It is a new type of transportation tool that can integrate human riding and motor assistance. Compared with ordinary bicycles, the biggest difference between power-assisted bicycles is that they have motors, batteries and control motherboards. The biggest difference from electric bicycles is that power-assisted bicycles do not have control valves (ordinary accelerator handles), but automatically complete the power-assisted acceleration process through the collaboration of power-assisted sensors and motor controllers. That is, power-assisted bicycles collect driving parameters through sensors to determine whether the rider needs motor assistance and how much power assistance is needed. Therefore, power-assisted sensors are one of the more important accessories in power-assisted bicycles.

[0003] However, the current power-assist sensors still have some shortcomings. For example, most of the existing power-assist sensors are directly put on the outside of the pedal crankshaft and then initially fixed by gaskets and finally fixed by installing the pedals. However, when the installer turns the nut for tightening, the power-assist sensor is easy to rotate with the rotation of the nut, causing the installation position to shift, thereby causing certain interference to the subsequent monitoring of the power-assist sensor, and thus there are certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structural deficiencies and provides a power assist sensor that is easy to install. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a power-assist sensor that is easy to install, comprising a bicycle frame and a sensor body, wherein a connecting shaft is installed through the interior of the bicycle frame, and a positioning groove is provided on the outside of the bicycle frame, the sensor body is fitted on the outside of the bicycle frame, and a signal connecting line is fixedly installed on the side of the sensor body, and a magnetic disk assembly is snap-fitted onto the outside of the sensor body.

[0007] Furthermore, the sensor body includes an annular mounting frame, a Hall sensor, a positioning rod, a limit groove and an auxiliary mounting mechanism, and the Hall sensor is fixedly installed on the top of the annular mounting frame, and the side of the Hall sensor is fixedly connected to the end of the signal connection line, and the inner side of the annular mounting frame is fixedly installed with a positioning rod in a circular shape and equidistantly, and at the same time, the outer side of the annular mounting frame is provided with limit grooves in a circular shape and equidistantly, and the inner surface of the annular mounting frame is embedded with an auxiliary mounting mechanism in a circular shape and equidistantly.

[0008] Furthermore, the outer dimensions of the positioning rod are completely consistent with the inner dimensions of the positioning slot, and the positioning rod forms a snap-fit ​​structure with the bicycle frame through the positioning slot.

[0009] Furthermore, the auxiliary installation mechanism includes a supporting cylinder, an elastic limiting mechanism, a connecting seat and a ball, and the inner surface of the supporting cylinder is installed with the elastic limiting mechanism, and the end of the elastic limiting mechanism is fixedly connected to the connecting seat, and the other end of the connecting seat is rotatably connected to the ball, and at the same time, the outer surface of the ball is fit-connected to the outer surface of the connecting shaft.

[0010] Furthermore, the end of the elastic limiting mechanism is fixedly connected to the inner surface of the bearing cylinder, and the other end of the elastic limiting mechanism is fixedly connected to the end of the connecting seat, and the connecting seat forms an elastic structure with the bearing cylinder through the elastic limiting mechanism.

[0011] Furthermore, the disk assembly includes an annular carrier plate, magnets and a limiting rod, and the interior of the annular carrier plate is provided with magnets embedded and installed at equal intervals in an annular shape, and the limiting rod is fixedly installed on the inner side of the annular carrier plate.

[0012] Furthermore, the outer dimensions of the end of the limiting rod are completely consistent with the inner dimensions of the limiting groove, and the limiting rod forms a snap-fit ​​structure with the annular mounting frame through the limiting groove.

[0013] The utility model provides a power-assisting sensor that is easy to install and has the following beneficial effects:

[0014] 1. The utility model provides a positioning rod so that the installer can initially fit and fix the sensor body to the outer surface of the bicycle frame when the sensor body is sleeved on the outer surface of the connecting shaft. Moreover, since the sensor body is fixed to the side of the bicycle frame by snapping, it effectively avoids the situation where the power-assisting sensor rotates with the rotation of the nut when the installer turns the nut for tightening, causing the installation position to shift and thus interfering with the subsequent monitoring of the power-assisting sensor. Moreover, since the sensor body and the disk assembly are assembled in a snap-fitting installation manner, it is more convenient for the installer to actually replace and install.

[0015] 2. The utility model provides an elastic limiting mechanism so that the ball bearings can always roll on the outer surface of the connecting shaft when the installer installs the annular mounting bracket, thereby providing convenience for the installer to disassemble and assemble the sensor body, and effectively ensuring that the sensor body can be firmly installed on the outer surface of the connecting shaft. The setting of the ball bearings also ensures that the sensor body will not interfere with the rotation of the connecting shaft after the positioning and installation are completed.
