Definitions

  • the present invention relates to a bicycle pedal, and more particularly, to a bicycle pedal capable of precisely measuring the amount of exercise of a bicycle rider.
  • Cycling is an exercise that develops cardiopulmonary function like other aerobic exercise such as walking and running. Because cycling exercise is more interesting than other exercises, it is a very beneficial exercise because it allows you to change your mood while doing physical activities for health. In particular, cycling is an exercise that can be done not only outdoors, but also indoors. Cycling helps people with weak lower extremity muscles, people with bad joints or back, and people with osteoporosis to improve their physical strength.
  • Cycling that is active indoors can control the amount of exercise of a cyclist by regulating the load. For example, when the load is increased, the cyclist must step on the bicycle pedal with greater force. In other words, a greater pressure is applied to the pedals for bicycles.
  • the amount of exercise of a bicycle occupant is calculated as the rotational RPM of the bicycle pedal.
  • a bicycle rider may have different power to step on the bicycle pedal. The exercise amount of the cyclist is further increased according to the force of the cyclist stepping on the pedal. Therefore, in the case of the prior art, there is a problem in that it is not possible to accurately and precisely calculate the amount of exercise of a cyclist.
  • An embodiment of the present invention aims to provide a pedal for a bicycle capable of precisely calculating an exercise amount of a bicycle occupant.
  • the pedal for a bicycle includes a case rotatable based on a spindle, a top plate rotatable based on the pivot axis connected to the case by a pivot shaft, and the inside of the case and a displacement generating assembly connected to the case and the upper plate to generate displacement according to rotation of the upper plate, and a sensing unit connected to the displacement generating assembly to sense displacement.

  • the pedal 1 for a bicycle includes a case 10, a top plate 20, and a displacement generating assembly 30 in order to accurately and accurately calculate the amount of exercise of a bicycle occupant. and a sensing unit 40 .
  • the case 10 is rotatable based on the spindle 11 .
  • the spindle 11 may be connected to a driving arm of a bicycle (not shown).
  • the driving arm is connected to a driving shaft (not shown) that rotates the wheel through a chain (not shown). Accordingly, the pedal 1 for a bicycle may rotate a wheel (not shown) through a driving arm.

  • the displacement generating assembly 30 is disposed inside the case 10 .
  • the displacement generating assembly 30 is connected to the case 10 and the upper plate 20 to generate displacement according to the rotation of the upper plate 20 .

  • the pressure applied to the pedal 1 for the bicycle increases in a state where the load is large.
  • the amount of momentum varies according to the pressure applied by the bicycle rider to the pedal 1 for the bicycle.

  • FIG. 7 is a main body shown in FIG. 6 . It is a diagram for explaining the operation of the 300 and the follower 310 .
  • the displacement generating assembly 30 includes a main part 300 and a follower part 310 .
  • the main body 300 is connected to the upper plate 20 .
  • the follower 310 is connected to the case 10 .
  • the driven part 310 is displaced by the main part 300 to move the sensing part 40 along a predetermined trajectory (T).
  • any one of the main part 300 and the driven part 310 includes a roller 301 .
  • the other of the main part 300 and the follower part 310 includes a contact part 302 .
  • the contact portion 302 has at least one of an inclined surface (S) and a curved surface facing the main portion (300).
  • the contact portion 302 may be gradually inclined in the downward direction of the main body 300 as it goes toward the main body 300 . Accordingly, when the main body 300 is rotated in the downward direction of the main body 300 with respect to the pivot shaft 21, the contact portion 302 is gradually pushed. At this time, the follower 310 may be rotated (front) based on the displacement axis X1. By the roller 301 and the contact portion 302, the driven portion 310 can smoothly change one movement direction of the main portion 300 to the other movement direction.
  • the follower 310 includes a follower 311 and a PCB panel 312 .
  • the follower 311 has a contact portion 302 disposed on one side thereof.
  • the follower 311 may be rotated based on the displacement axis X1 by the main part 300 .
  • the displacement axis X1 may be disposed perpendicular to a plane P through which a predetermined trajectory T of the sensing unit 40 passes. Thereby, the movement of the main part 300 may be changed to the rotation of the follower part 310 with respect to the displacement axis X1. That is, it is possible to precisely sense the amount of rotation of the upper plate 20, despite the narrow space constraint.
  • the pedal 1 for a bicycle rotates based on the spindle 11 and the aforementioned drive shaft (not shown). That is, the sensing unit 40 must precisely measure the change in pressure applied to the upper plate 20 regardless of the rotation of the case 10 .
  • the displacement generating assembly 30 moves the sensing unit 40 on a plane P disposed between the upper plate 20 and the case 10 . Since one plane P itself rotates together with the case 10 , when the sensing unit 40 moves on one plane P, only a change in pressure applied to the upper plate 20 can be precisely detected. That is, the sensing unit 40 can precisely measure the pressure change according to the rotation of the upper plate 20 irrespective of the rotation with respect to the spindle 11 or the aforementioned driving shaft (not shown).
  • the sensing unit 20 is disposed to be spaced apart from the displacement axis X1 toward the pivot axis 21 . That is, the sensing unit 20 is disposed between the displacement axis X1 and the pivot axis 21 . Accordingly, the sensing unit 20 may be disposed to be spaced apart from the displacement axis X1. In this case, the sensing unit 20 may have a large displacement with respect to the displacement axis X1. That is, even if the contact portion 302 is displaced relatively small by the main body 300 , the sensing unit 20 may be displaced relatively large. Accordingly, it is possible to secure a sufficient sensing range of the sensing unit 20 .
  • the sensing unit 20 may sense at least one of the rotation angle A and the linear displacement amount D.
  • the rotation angle A is the rotation angle of the sensing unit 20 with respect to the displacement axis X1.
  • the linear displacement amount D refers to a movement distance of a straight line X2 passing through the center of the sensing unit 20 and perpendicular to the pivot axis 21 in the pivot axis 21 direction.
  • the sensing unit 20 may be at least one selected from an acceleration sensor, a gyro sensor, and a 6-axis sensor.
  • the sensing unit 20 may be a 6-axis sensor.
  • the sensing unit 20 may be disposed on the PCB panel 312 .
  • the first return spring 320 restores the driven portion 310 displaced by the main portion 300 to its original position.
  • the first return spring 320 may be connected to the case 10 and the follower 310 .
  • the second return spring 50 restores the upper plate 20 rotated by the cyclist to its original position.
