Description

Pedal movement signal detection and transmission device

The present invention provides a foot pedal motion signal detection and transmission device, in particular a pressure sensing signal generated by a pressure sensing element, and then a rotation sensing element is sensed with the sensed element to generate a rotation sensing signal, Into the detection transmission device to provide the rider as a reference information during exercise.

In order to maintain a healthy posture or to lose weight due to obesity, modern people often adjust their physiological functions through appropriate exercise to meet their health needs. Among them, bicycles can not only improve cardiopulmonary function, but also affect back muscles, buttocks and The exercise of the lower limbs also has a good effect, so it is quite popular and welcomed by those who like sports.

However, when riding a bicycle, the pedal must be continuously stepped on to achieve the effect of exercise. After a long time, it is easy to cause sports injuries to the rider and cannot improve the efficiency of riding. Therefore, there is now a recordable ride. Each time the rider’s motion status or motion detection, the left and right foot motion force signals are generated for the rider to use as reference information during exercise, so that the rider can adjust exercise habits and improve riding during exercise. The efficiency of multiplication is produced by various sensing devices.

For example, US patent US 8011242 B2 has four sensing elements on both sides of the pedal axis stator to detect and analyze the strength of the force exerted by the rider on the bicycle pedal and the force distribution on the surface of the bicycle pedal The force on the rider can get Continuously rotating relevant data can improve its pedaling efficiency to achieve a better bicycle exercise effect. However, in this conventional technology, the motion signal detected by the sensing element must be transmitted through the cable and then through the connector Connected to the other end, the structure is complicated and the wiring is pulled out from one side of the pedal connected to the bicycle, which causes the wires to be exposed and easily cause danger.

In addition, this conventional technology places four sensors (up, down, left, and right) on both sides of the stator. When the rider steps on the pedal, the pedal rotor does not necessarily step on the sensor, and it may also step on the sensor. The position between the sensor and the sensor, so that the pedaling force sensed by the sensor is incorrect, not the real pedaling force, so its accuracy is not good.

Furthermore, the sensing device used to calculate the number of turns is set in the pedal body, and the signal sensed by the sensing device must also be transmitted through wiring and connected to an external electronic component to signal it. Related processing, therefore, its US patent US 8011242 B2 is not a good design.

Another example is the "Foot Pedal Movement Signal Detection Device" of Taiwan Patent Nos. I595910 and I596324, which are mainly equipped with one or more pressure sensing units on the outer edges of both sides of the casing, and the outer edge of the casing The middle position ring is provided with at least one pressure signal connection device, which is connected to the pressure signal connection device through the signal reading unit of the control circuit board to read the movement signal detected by the pressure signal connection device and the pressure sensing unit, and The read motion signal is processed by a signal processing unit, and then transmitted to the display through a wireless transmission module for the rider to use as reference information during exercise.

However, although the aforementioned patents are all equipped with pressure sensing units on the outer edges of both sides of the casing to perform related pressure sensing, during pressure sensing, for example, as shown in I595910, the casing is hollow inside. When the casing is stepped on by the rider, there is no relevant support inside the casing The force can support the casing, so it is easy to make the obtained pressure value deviate. Another example is shown in I596324. Although a positioning shaft is penetrated inside the casing, the two ends of the casing are completely attached to the collar and the bearing. Therefore, when the casing is under the pedaling force of the rider, it cannot Provide enough elastic space for the sleeve, therefore, it is easy to cause deviation of the obtained pressure value.

In addition, the aforementioned I595910 and I596324 patents will not disclose the related technology for calculating the number of turns, so they cannot provide the rider with more complete sports reference information.

Please refer to FIGS. 1 to 5, which are the three-dimensional view, the exploded view, the exploded view of the shaft and the sleeve, the cross-sectional view, and the block diagram of the control circuit board of the present invention. As shown in the figure, the present invention is mainly composed of a pedal 10, a sleeve 20, a shaft 30 and a control circuit board 40, wherein the pedal 10 is provided with a pedal portion 11 on one side, and the pedal portion 11 At least one limiting portion 111 is provided on the upper surface to limit the riding position of the rider within a limited area RA through the limiting portion 111.

And on the outer edge of the sleeve 20 is provided with a plurality of pressure sensing elements 60 and a connecting electrical The road board 61, wherein each of the pressure sensing elements 60 is specifically a strain gauge, which is arranged around the two ends of the sleeve 20 in a spaced manner, and the arrangement position of each of the pressure sensing elements 60 is the same as The restricted area RA corresponds, and the connecting circuit board 61 is arranged around the middle position of the sleeve 20, and the connecting circuit board 61 is connected with each of the pressure sensing elements 60 to receive each of the pressure sensing elements. At least one pressure sensing signal 601 generated by the sensing element 60. A sensing portion 21 is further provided on the outer edge of the sleeve 20, and the sensing portion 21 is specifically a penetrating space.

One end of the shaft 30 penetrates into the sleeve 20, so that part of the shaft 30 is accommodated in the first accommodating portion 12, and the shaft 30 is pivotally connected to the sleeve 20. A sensed element 70 is provided on the outer edge of one end of the shaft 30, and the sensed element 70 is provided at a position directly opposite to the sensing portion 21. Wherein, a bearing 31 is provided between the shaft 30 and the sleeve 20, and the bearing 31 can provide rotation between the shaft 30 and the sleeve 20 (when the sleeve 20 rotates, it will drive the pedal 10 to rotate). In addition, a sleeve ring 32 is further sleeved on the shaft 30, so that the sleeve 20 is located in the first receiving portion 12 between the sleeve ring 32 and the locking element 50, and , There is a gap 22 between the collar 32 and the sleeve 20, the gap 22 can provide a deformation space for the sleeve 20, and there is also a gap between the shaft 30 and the collar 32 or the sleeve 20 At least one bearing 33 is provided to provide maintenance-free, corrosion-resistant, shock-resistant, dust-resistant, low-noise and other functions.

The control circuit board 40 is arranged in the second accommodating portion 13, and the control circuit board 40 is provided with a connecting body 41, a rotation sensing element 42, a signal processing module 43 and a transmission module 44, The connecting body 41 is used to connect with the connecting circuit board 61 to receive the pressure sensing signal 601, and the rotation sensing element 42 is arranged in a position directly opposite to the sensed element 70, and is connected to the There is a sensing space between the sensed elements 70, and the rotation sensing element 42 senses the sensed element 70 to generate a rotation sensing signal 421, wherein the sensed element 70 may be further provided with A sensed portion 71, the sensed portion 71 is disposed at a position facing the rotation sensing element 42, and the sensed portion 71 may be composed of a magnetic or non-magnetic element to provide the Rotate the sensing element 42 to perform related sensing. The signal processing module 43 is connected to the connecting body 41, the rotation sensing element 42 and the transmission module 44 to receive the pressure sensing signal 601 or the rotation sensing signal 421, and the pressure sensing signal 601 or the rotation sensing signal 421 is transmitted to the transmission module 44, and the pressure sensing signal 601 or the rotation sensing signal 421 is sent to a display element through the transmission module 44 for the rider to use as exercise time Reference information.

In addition, the pedal motion signal detection and transmission device further includes a power supply body 80 which is disposed in the second accommodating portion 13 to provide the control circuit board 40 and the connection circuit board 61 And the power for each of the pressure sensing elements 60 to work.

In this way, with the technical features disclosed above, when a rider rides a bicycle to step on the pedal portion 11, the limit portion 111 is provided on the pedal portion 11 to restrict the pedaling of the rider. Therefore, when the rider steps on the pedal 10, the foot can be effectively stepped on each of the pressure sensing elements 60. When each of the pressure sensing elements 60 senses the pressure of its pedaling, each of the pressure sensing elements 60 will sense the change of the rider's pedaling position to obtain the space of the rider on the pedal part. The motion information of the angular position further generates at least one pressure sensing signal 601, and then transmitting the pressure sensing signal 601 to the signal processing module 43 through the connecting circuit board 61 for signal related processing.

However, when each pressure sensing element 60 senses the pressure of its pedaling, the sleeve 20 will deform in the deformation space to effectively provide each pressure sensing element 60 for pressure sensing. For example, when a rider steps on the pedal 10, the sleeve 20 will also receive a pressure generated by the stepping. In this way, the force position of the sleeve 20 may be slightly facing The two ends of the sleeve 20 may be slightly tilted upward, but if the distance 22 is not provided between the sleeve 20 and the collar 32, when the sleeve 20 is stressed, the sleeve 20 The ring 32 supports one end of the sleeve 20 so that the pressure sensing elements 60 cannot accurately sense the pressure received by the sleeve 20.

In addition, the pedal that is stepped on can be connected to the crank on the bicycle through the axle 30. Therefore, when the rider rides the bicycle, the axle 30 is connected to the crank, and the pedal 10 is connected to the crank. The cylinder 20 rotates on the shaft 30, and because the control circuit board 40 is provided with the rotation sensing element 42, and the shaft 30 is provided with the sensed element 70 to interact with the rotation The sensing element 42 senses each other, so when the pedal 10 rotates on the axis 30, the rotation sensing element 42 will also rotate around the axis 30.

When the rotation sensing element 42 leaves the position directly opposite to the sensed element 70 due to rotation, the rotation sensing element 42 will not be able to sense the sensed element 70, and when the rotation sensing element When 42 returns to a position directly opposite to the sensed element 70, the rotation sensing element 42 will then sense the sensed element 70, so the rotation sensing element 42 repeatedly senses the The sensed element 70 and the rotation sensing element 42 can generate a rotation sensing signal 421 by sensing the information of the sensed element 70. The generation period of the rotation sensing signal 421 may be that each time the rotation sensing element 42 senses the sensed element 70, the rotation sensing signal 421 is generated, or by the rotation sensing The number of times that the sensing element 42 senses the sensed element 70 within a period (for example, 1 second, 3 seconds, 5 seconds or other time periods), generates the rotation sensing signal 421.

The above-mentioned mutual sensing relationship between the rotation sensing element 42 and the sensed element 70 is when the sensed element 70 is composed of a magnetic element, and the sensed element 70 is set on the axis 30 When the outer edge is placed at a specific position, instead of being sleeved on the shaft 30 in a ring-shaped manner, However, in this embodiment, the sensed element 70 is sleeved on the axis 30 in a ring-shaped manner, and the sensed part 71 is provided on the sensed element 70 as an example. The description is based on the possible deformation of this embodiment, but is not limited to this.

When the sensed element 70 is composed of a non-magnetic element, and the sensed portion 71 is composed of a magnetic element, the sensing portion 21 provided on the sleeve 20 will be a penetrating Space is provided for the rotation sensing element 42 to sense the sensed portion 71. Therefore, when the rotation sensing element 42 rotates and leaves a position directly opposite to the sensed portion 71, the rotation sensing element 42 will not be able to sense the sensed portion 71, and when the rotation sensing element 42 returns to a position directly opposite to the sensed portion 71, the rotation sensing element 42 will sense again The sensed portion 71 thereby repeatedly senses the sensed portion 71 to generate the rotation sensing signal 421.

When the sensed element 70 is composed of a magnetic element, and the sensed portion 71 is composed of a non-magnetic element (the sensed portion 71 may also be a hollow portion), it is provided in the sleeve The sensing portion 21 on the 20 can be a shielding body, and the space surrounding the axis 30 with the sensing portion 21 as a reference point is a surrounding penetrating space, so that when the rotation sense When the sensing element 42 leaves the position directly opposite to the sensed portion 71 due to rotation, the rotation sensing element 42 will sense the sensed element 70, and when the rotation sensing element 42 returns to and When the sensed portion 71 is in an opposite position, the rotation sensing element 42 can no longer sense the sensed element 70, so when the rotation sensing element 42 cannot sense the sensed element At 70 o'clock, it means that the rider has stepped on the crank for one revolution. At this time, the rotation sensing element 42 can generate the rotation sensing signal 421.

Finally, the signal processing module 43 will receive the pressure sensing signal 601 and/or the rotation sensing signal 421 for related signal processing, and then transmit the signal to the transmission module 44 to use the The transmission module 44 sends the processed signal to the display element, so, The rider can know the force state or angular position of stepping on the pedal 10 through the display element, or the riding distance and the number of laps, etc., and then provide the rider as an exercise Reference information.

, Please refer to Figures 6 to 8, which are the cross-sectional view of the three-axis accelerometer embodiment of the present invention, the detection module and the control circuit board block diagram of the three-axis accelerometer embodiment, and the three-dimensional schematic diagram of the positive and negative induction magnetic pole embodiment . As shown in the figure, the control circuit board 40 may be further provided with a three-axis accelerometer 45 and a detection module 46, wherein the three-axis accelerometer 45 is connected to the signal processing module 43, and the three-axis accelerometer 45 is connected to the signal processing module 43. The accelerometer 45 measures the direction and speed of the pedal 10, and generates a measurement signal 451 to send to the signal processing module 43. The signal processing module 43 uses the measurement signal 451 to calibrate the rotation sensing signal 421 , Or the signal processing module 43 transmits the measurement signal 451 to the transmission module 44, so as to send the measurement signal 451 to the display element through the transmission module 44; and the detection module 46 Connected to the power supply body 80 and at least one indicator light 90, the detection module 46 is used to detect the circuit operation status of the control circuit board 40 and the power of the power supply body 80 to generate a detection signal 461, When the detection module 46 detects that the control circuit board 40 is not operating normally, or the detection module 46 detects that the power of the power supply body 80 is lower than a power threshold, the detection module 46 sends a detection signal 461 The display light 90 is transmitted to make the display light 90 light up, thereby reminding the rider that the control circuit board 40 operates abnormally, or the power supply body 80 is too low.

In addition, in addition to the above-mentioned examples, the sensed element 70 can also be a ring-shaped or C-shaped magnet, and the sensed element 70 has at least a positive induction magnetic pole 72 and a negative induction magnetic pole 72. The magnetic pole 73 (may also have more than two positive induction magnetic poles 72 and two or more negative induction magnetic poles 73), and the rotation sensing element 42 will be provided with at least two of the rotation sensing elements 42 to interact with Each of the positive induction magnetic pole 72 and the negative induction magnetic pole 73 induces each other. For example, when the sensed element 70 is driven to rotate by the shaft 30, each of the rotation sensing elements 42 will continue to sense the positive The induction magnetic pole 72 and the negative induction magnetic pole 73, however, due to the deviation of the installation positions of the rotation sensing elements 42 (even if the two rotation sensing elements 42 are arranged in parallel, the sensing positions are also different), so assume When one of the rotation sensing elements 42 first senses the positive induction magnetic pole 72, and the other rotation sensing element 42 senses the positive induction magnetic pole 72 later, it can be determined that the pedal 10 is rotating in a clockwise direction. However, if the other rotation sensor element 42 first senses the positive induction magnetic pole 72, and then the other rotation sensor element 42 senses the positive induction magnetic pole 72, it can be determined that the pedal 10 is moving counterclockwise. Rotational movement.

In addition, through the conversion of the positive induction magnetic pole 72 and the negative induction magnetic pole 73, the number of pedaling cycles can also be calculated, for example, when the two rotation sensing elements 42 respectively sense the positive induction magnetic pole 72 and the negative induction magnetic pole 73 , Will generate two rotation sensing signals 421 (a rotation sensing signal 421 is generated when the rotation sensing element 42 senses the positive induction magnetic pole 72), so when the signal processing module 43 receives Fourth, when the rotation sensing signal 421 is used, it can be judged that the number of stepped laps is one lap, and so on, and finally the information is displayed by the display element to the rider for reference.

For another embodiment of the present invention, please refer to FIGS. 9 and 10 again. The control circuit board 40 and the power supply body 80 are located at the opposite position of the footrest 11, but also on the pedal 10. On one end or around it to achieve the desired effect of the invention.

In this way, the rider can also know the force state or angular position of stepping on the pedal 10 through the display element, or the riding distance and the number of laps, etc., which are then provided to the rider as Reference information during exercise.
