Description

Technical Field

[0001] This application relates to the field of cycling power measurement technology, and in particular to a non-centralized cycling power pedal. Background Technology

[0002] Cycling power pedals, as an important bicycle accessory, have been widely used in cycling training and competition in recent years. They calculate power by measuring the force generated by the rider on the pedals and combining this with the pedal's angle of motion, providing riders with accurate training data and feedback. However, existing cycling power pedals have some design shortcomings that affect user experience and safety.

[0003] Current cycling power pedals generally employ a centralized design, placing all internal modules and components in a single location on the pedal. To protect these components, a raised protective shell is typically installed on the pedal. However, this design can easily lead to users failing to unlock the pedal due to uneven surfaces, potentially causing falls and other safety issues. Utility Model Content

[0063] It should also be noted that the specific embodiments or implementation methods described below are a series of optimized settings listed in this application to further explain the specific application content, and these settings can be combined or used in conjunction with each other.

[0064] The present application will be further explained below with reference to specific implementation methods.

[0065] like Figure 1 ,2 As shown in Figures 4, 6, and 7, this embodiment provides a non-centralized cycling power pedal, including a pedal body 110, a housing 120, and a power meter 200.

[0066] The power meter 200 is disposed inside the cylindrical housing 120. The housing 120 and the pedal body 110 are an integral structure. The power meter 200 is used to measure the force applied by the rider to the bicycle pedal during pedaling and the pedaling frequency under the action of the force, thereby calculating the actual output power of the rider.

[0067] The power meter 200 includes an inner housing 210 and a connecting end 220;

[0068] The inner shell 210 has a columnar structure;

[0069] The connecting end 220 is located at the axial end of the inner housing 210 and extends out of the receiving housing 120 for connection with a bicycle.

[0070] As a further embodiment of this embodiment, the power meter 200 also includes a long axis 230, a strain gauge 240, a PCB board 250, and a battery 260;

[0071] The strain gauge 240, the PCB board 250, and the battery 260 are sequentially arranged on the long axis 230 along the axial direction of the long axis 230.

[0072] Compared with existing technologies, the non-centralized cycling power pedal disclosed in this embodiment has its strain gauges 240, PCB board 250, and battery 260 distributed at different positions on the long axis 230, whereas existing technologies generally concentrate these components at one end (e.g., Figure 3 , 5 As shown in the figure, the housing 120 has a protruding structure 300 for accommodating the centrally placed components. In this application, the housing 120 is a columnar structure, preferably cylindrical, so that the housing 120 can avoid the user failing to unlock due to uneven foot surface during actual use, thus preventing safety problems such as falls.

[0073] like Figure 6 , 7 As further embodiments of this example, 9, 10, and 11, multiple strain gauges 240 are provided;

[0074] Multiple strain gauges 240 are attached to the outer peripheral curved surface of the long axis 230 in a circular array at the same horizontal height;

[0075] Alternatively, the strain gauge 240 is an integral ring structure, sleeved on the long axis 230;

[0076] Alternatively, the strain gauge 240 may be a single spiral structure, coiled around the long axis 230.

[0077] like Figures 9-11 As shown, when strain gauges 240 are arranged in a ring array at the same horizontal height and attached to the outer circumferential curved surface of the long axis 230, the strain gauges 240 collect deformation in any direction of multiple curved surfaces, calculate the output force, and combine it with rotational speed information to obtain real-time power data. When the strain gauge 240 is an integral ring structure and is fitted onto the long axis 230, the integral ring strain gauge 240 can more accurately measure the strain in different directions, thus obtaining more accurate data. When the strain gauge 240 is a spiral structure and coiled around the long axis 230, the strain gauge 240 can receive stress deformation feedback from 360 degrees, thus more accurately measuring the force change at each angle, and obtaining more accurate force data after comprehensive processing by the PCB board 250. In addition, the spiral structure strain gauge 240 can be directly attached to the long axis 230 without the need to process a flat surface, reducing production difficulty and process cost.

[0078] like Figures 6-7 As shown, as a further embodiment of this example, the power meter 200 also includes a frame 270;

[0079] The sleeve 270 is fitted onto the outer wall of the long axis 230 between the strain gauge 240 and the PCB board 250;

[0080] There is a gap between the sleeve 270 and the outer wall of the long shaft 230 for the signal line to pass through;

[0081] The two ends of the signal line are electrically connected to the strain gauge 240 and the PCB board 250, respectively.

[0082] like Figures 6-7 As shown, as a further embodiment of this example, the PCB board 250 is annular and sleeved on the long axis 230;

[0083] The upper end of the PCB board 250 is fixedly connected to the end of the frame 270 by fasteners.

[0084] As a further embodiment of this example, the power meter 200 also includes a gyroscope sensor 280;

[0085] The gyroscope sensor 280 is fixedly mounted on the frame 270 and electrically connected to the PCB board 250.

[0086] like Figure 6 As shown, in a further embodiment of this example, the gyroscope sensor 280 is provided with two sensors;

[0087] The two gyroscope sensors 280 are vertically arranged;

[0088] After sensing the position and attitude, the two gyroscope sensors 280 transmit the position and attitude information to the PCB board 250 respectively. The PCB board 250 compares whether the two position and attitude information are perpendicular to each other. If they are perpendicular, the position and attitude information of the gyroscope sensor 280 is accepted. If they are not perpendicular, it indicates that at least one of the gyroscope sensors 280 has failed.

[0089] The gyroscope sensor 280, installed inside the pedal, accurately measures cadence by detecting the pedal's rotational angular velocity and calculating revolutions per minute in real time. This is one of the core parameters for power meter calculation, and combined with torque data, instantaneous power output can be derived. Furthermore, the gyroscope sensor 280 can also monitor the pedal's rotational attitude in three-dimensional space (such as pitch, yaw, and roll), analyzing the smoothness and symmetry of pedaling motion to help identify inefficient or asymmetrical force application habits. Working in conjunction with a strain sensor (measuring crank force), it achieves high-precision power output calculation using the formula power = torque × angular velocity, reducing errors, especially under complex riding postures. On bumpy roads or in non-standard riding postures, the gyroscope sensor 280 can filter linear acceleration interference, ensuring the stability of cadence data and improving overall measurement reliability. In addition, by analyzing the pedal's motion trajectory and force distribution, it can also provide suggestions for optimizing pedaling efficiency (such as increasing the proportion of the "effective power zone"), helping athletes improve their technique.

[0090] In order to evaluate the reliability of the gyroscope data during use, this embodiment sets up two adjacent gyroscope sensors 280 with an included angle of 90 degrees. The two gyroscope sensors 280 measure the angular velocity along different axes. Ideally, when the pedal rotates around the main rotation axis (such as the horizontal axis), one gyroscope (along the main rotation axis) should show a high angular velocity, while the other orthogonal gyroscope (perpendicular to the main rotation axis) should be close to zero. If the orthogonal gyroscope detects a significant angular velocity, it indicates that the main gyroscope may be malfunctioning (such as drift or noise) or that the pedal is experiencing unexpected lateral swaying (such as loose installation or abnormal riding posture). In addition, by comparing the data of the two, the system can identify outliers. For example, if the deviation between the main gyroscope data and the "zero value" of the orthogonal gyroscope is too large, it can be determined that the main sensor is malfunctioning. From the perspective of angular velocity vector decomposition, any three-dimensional rotation can be decomposed into angular velocity components along three orthogonal axes (such as X / Y / Z). If the two gyroscopes are installed along the X and Y axes respectively, their measured values ​​should satisfy:

[0091]

[0092] If no sensor is installed on the third axis (Z-axis), the theoretical value can be inferred from the X / Y axis data and compared with the actual measured value to verify the rationality of the data.

[0093] When interference occurs in the environment, common-mode interference such as vibration and temperature changes may affect both gyroscopes simultaneously. However, due to the orthogonal installation orientation, the coupling effect of the interference differs on the two axes. For example, oscillation noise manifests as high-frequency vibration on the X-axis, while it may be suppressed on the Y-axis; temperature-induced zero-bias drift may exhibit different amplitudes on different axes. Separating common-mode interference from the real signal through algorithms can improve data reliability.

[0094] In addition, the data from the two gyroscopes are weighted and fused, for example:

[0095]

[0096] The weight α is dynamically adjusted based on the sensor's accuracy to ensure that the main sensor dominates the calculation, while the secondary sensor serves as a verification. If the data from a certain gyroscope exceeds a preset threshold (such as a sudden change in variance or a continuous deviation), the system can automatically switch to data from another sensor to avoid single-point failure.

[0097] like Figure 4 , 8 As shown, as a further embodiment of this example, the inner shell 210 has a multi-segment structure, including a fixed segment 211 and a rotating segment 212.

[0098] The fixed section 211 is fixedly connected to the power meter 200 and has no relative movement with the power meter 200 during use;

[0099] The rotating section 212 is fixedly connected to the inner wall of the housing 120 and is connected to the power meter 200 through a bearing 290. During use, it is driven by the foot pedal body 110 and moves relative to the power meter 200.

[0100] As a further embodiment of this embodiment, the fixing segment 211 includes a first fixing sleeve 211a and a second fixing sleeve 211b;

[0101] The first fixing sleeve 211a covers the area where the strain gauge 240 is located;

[0102] The second fixing sleeve 211b covers the area where the PCB board 250 and the gyroscope sensor 280 are located.

[0103] Preferably, the first fixing sleeve 211a is an aluminum sleeve, used to shield the strain gauge 240 from external signal interference and to strengthen the overall structural strength.

[0104] As a further embodiment of this embodiment, the frame 270 includes a fixed connection area 271 and a rotating connection area 272;

[0105] The fixed connection area 271 is used to fix the gyroscope sensor and the PCB board 250;

[0106] The rotating connection area 272 is used to rotatably connect to the rotating section 212 of the inner housing 210 via a bearing 290.

[0107] As a further embodiment of this embodiment, the rotating segment 212 includes a main rotating sleeve 212a and a secondary rotating sleeve 212b;

[0108] The main rotating sleeve 212a is sleeved on the rotating connection area 272 of the frame sleeve 270 via the first bearing 291;

[0109] The auxiliary rotating sleeve 212b is mounted on the main shaft between the battery 260 and the PCB board 250 via the second bearing 292.

[0110] As a further embodiment of this embodiment, the first bearing 291 is a needle roller bearing 290;

[0111] The second bearing 292 is a multi-row deep groove ball bearing 290.

[0112] The non-centralized cycling power pedal disclosed in this application divides the inner housing 210 into multiple segments. The fixed segment 211 serves to protect important electronic components, while the rotating segment 212 provides structural support to the internal structure and allows relative rotation between the internal structure and the outer housing 120.

[0113] The foot pedal body 110 corresponding to the main rotating sleeve 212a is the main stress point when pedaling. To maintain stability at this location, a needle roller bearing 290 with a longer axial length is selected as the first bearing 291. To avoid friction and other obstacles caused by radial deformation at the rotating end of a single bearing 290, a secondary rotating sleeve 212b is provided. The secondary rotating sleeve 212b is positioned relatively outward relative to the main rotating sleeve 212a, making it prone to radial deformation. Therefore, if a needle roller bearing 290 were used as the second bearing 292, similar to the main rotating sleeve 212a, the bearing 290 would easily be damaged. Thus, a multi-row deep groove ball bearing 290 is chosen at the end, which not only provides auxiliary rotational capability as the bearing 290 but also reduces damage caused by radial bending at the end, thus lowering the failure rate of the device.

[0114] As a further embodiment of this embodiment, the battery 260 is provided with a magnetic charging port 261;

[0115] The magnetic charging port 261 is located at the end of the battery 260 away from the long axis 230, and is used to connect to an external power source for charging.

[0116] As a further embodiment of this embodiment, the long axis 230 is a hollow structure;

[0117] Through holes are provided on the long axis 230 at positions corresponding to the strain gauge 240, the PCB board 250, and the battery 260;

[0118] The wire is placed in the hollow groove of the long shaft 230 and electrically connects the battery 260 to the strain gauge 240 and the PCB board 250 to facilitate power supply to the battery 260.

[0119] The decentralized cycling power pedal disclosed in this application places the power cord inside the long shaft 230 and the signal line inside the frame 270. This not only separates the wire from the component, but also separates the power cord from the signal line. This wiring method is orderly and avoids confusion, making it more convenient and safer in production, use and maintenance.

[0120] As a further embodiment of this invention, an oil seal 231 is provided on the side of the long shaft 230 near the connecting end 220 to prevent external dust or liquid from entering the power meter 200 and causing damage to the structure and internal components.

[0121] By adopting the above technical solution, this application has the following beneficial effects:

[0122] (1) By distributing the internal components of the power meter 200, such as strain gauges 240, PCB board 250 and battery 260, on the long axis 230 and using a columnar housing 120, the protruding structure 300 on the housing 120 is avoided, making the pedal surface flatter and reducing the risk of riders falling due to uneven pedals when unlocking, thus improving riding safety and comfort.

[0123] (2) The strain gauge 240 adopts a variety of arrangement methods, such as a ring array, an integral ring or a spiral structure, which can more comprehensively collect the deformation of the long axis 230 in different directions, thereby more accurately calculating the rider's output force.

[0124] (3) By combining the use of the gyroscope sensor 280, the pedal frequency can be accurately measured and the rotational attitude of the pedal in three-dimensional space can be monitored, further improving the accuracy and reliability of power measurement. Especially under complex riding postures or bumpy road conditions, the stability of the data can still be ensured.

[0125] (4) The inner housing 210 adopts a multi-segment structure, including a fixed segment 211 and a rotating segment 212, which are connected by a bearing 290. This protects the internal electronic components and allows relative rotation between the foot pedal body 110 and the power meter 200.

[0126] (5) The main rotating sleeve 212a adopts needle roller bearing 290 and the auxiliary rotating sleeve 212b adopts multi-row deep groove ball bearing 290. The design is optimized for the force characteristics of different positions, which enhances the stability and durability of the structure and reduces the failure rate.

[0127] (6) A magnetic charging port 261 is provided on the battery 260, which makes it easy to connect to an external power source for charging. The battery 260 can be maintained without disassembling the foot pedal, which improves the convenience of use.

[0128] (7) The wires and signal lines are respectively installed inside the long shaft 230 and the frame 270. The wiring method is orderly and avoids confusion, making production, use and maintenance more convenient and safe.

[0129] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
