Description

Pressure device for bicycle

This creation is related to bicycles, especially a pressing device for bicycles.

With the improvement of environmental protection concepts, the popularization of public transportation, and the popular sports atmosphere, people are more and more often using bicycles to replace other means of transportation, especially in cities. People who take public transportation often cooperate with public bicycles to move outside the station. Locally, bicycles have become the favorite mobile tool of urbanites. However, ordinary riders cannot know their own moving speed when riding a bicycle. They can only calculate a rough average speed based on riding experience or afterwards using riding distance and riding time, which makes it impossible for the rider to estimate in advance. The movement time or the intensity you want to achieve during training. Therefore, people in the related field have developed a speed sensor to solve this problem.

A common speed sensor is to install a magnet on the spoke and a sensor on the fork lever. The frequency of the signal generated by the magnet through the sensor can be used to figure out the riding frequency, speed and other related information. The other type of speed sensor is to add a sensing magnet plate to the crank to cooperate with the sensor to detect the speed. However, this combination structure takes up too much assembly space, increases the overall weight, and requires additional design of the magnet plate and other components. The connection structure and other shortcomings.

Therefore, it is necessary to provide a novel and progressive tightening device for bicycles to solve the above-mentioned problems.

It is worth mentioning that the urging device for bicycles further includes at least one connecting member 3, and the at least one connecting member 3 passes through the at least one magnetic unit 2 and is connected and positioned on the pressing portion 12 to further strengthen The bonding strength of the at least one magnetic unit 2 and the pressing portion 12. In addition, the at least one connecting member 3 does not protrude from the at least one magnetic unit 2, so as to ensure that the contour of the outer surface is flat and reduce unintended interference.

In this embodiment, the number of the at least one concave portion 13 is one, the number of the at least one magnetic unit 2 is one, the mounting plate 21 is an iron sheet for the magnet 24 to attract, and the at least one connecting member 3 The number is two. One end of the mounting plate 21 is provided with two legs 23, and the other end is provided with the accommodating groove 22. The distance between the pieces 3 is greater than the maximum inner diameter of the pocket 22; wherein, the connecting piece 3 is a countersunk screw.

Preferably, the recessed portion 13 is recessed on a side of the pressing portion 12 facing away from the disc 6 to facilitate assembly or disassembly.

Preferably, the pressing portion 12 includes a ring body 14 extending in an arc shape. In the radial direction of the ring body 14, the magnetic unit 2 is positioned and protrudes from the ring body 14 to facilitate shortening The distance to the sensor improves the accuracy of the sensing.

Preferably, the plurality of tooth grooves 15 are recessed in the hole edge of the ring body 14 along the radial direction of the ring body 14, so that the user can fit the plurality of tooth grooves 15 through other driving tools to drive the body 1 Whirl.

Preferably, the urging device for bicycle further includes a glue 4 which is adhered between the concave portion 13 and the magnetic unit 2 to further enhance the positioning of the magnetic unit 2 in the concave portion 13 The effect is to greatly improve the stability of the combination, and prevent the possibility of falling off and displacement.

It can be understood that the configuration of the magnetic unit 2 and the recess 13 is not limited to the above-mentioned aspect, and can be changed arbitrarily according to different requirements.
