Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, specifically to a disc-type power data detector. Background Technology

[0002] With the popularization of cycling and the improvement of competitive levels, it has become increasingly important to accurately monitor the training effects of cyclists. As a key device for evaluating the riding efficiency of cyclists, the accuracy and reliability of power meters are directly related to the accuracy of training data and the formulation of athlete training plans.

[0003] Traditional power meters typically use pedal force sensors or crank torque sensors to measure power output during cycling. Pedal force sensors are easily affected by changes in pedaling posture and force application, leading to significant measurement errors. While crank torque sensors can reflect cycling torque to some extent, their installation location and measurement principle limit their ability to accurately capture real-time power changes under complex cycling conditions, such as frequent gear changes and uphill climbing, thus affecting measurement accuracy. Furthermore, they usually lack waterproofing, making their electronic components susceptible to moisture corrosion in rainy or humid environments. Water ingress can cause short circuits and damage to electronic components, affecting the accuracy and lifespan of the meter. Therefore, a disc-claw type power data meter is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a disc-claw type power data detector, which has advantages such as good waterproof performance and accurate detection, solving the problems of insufficient measurement accuracy and poor waterproof performance of traditional power meters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a claw-type power data detector, comprising a main structure and a shell, wherein the shell is wrapped around the outer surface of the main structure, and the main structure contains a battery compartment and a waterproof potting groove. The battery compartment contains a battery, and the waterproof potting groove contains a main board. The main board contains a strain gauge sensor, a signal conditioning circuit, a microprocessor unit, and a data transmission system, and the strain gauge sensor, the signal conditioning circuit, the microprocessor unit, and the data transmission system are electrically connected.

[0006] Furthermore, the main structure is made of aluminum alloy, the outer shell is made of ABS, and a waterproof sealing ring is provided between the main structure and the outer shell.

[0007] Furthermore, the claw-type power data detector has an input section in the middle and an output section around its perimeter.

[0008] Furthermore, the outer surface of the housing is provided with a display screen and buttons.

[0009] Furthermore, the strain gauge sensor is tightly bonded to a specific stress area of ​​the main structure using special adhesive.

[0010] Furthermore, the signal conditioning circuit is composed of a filter circuit, an amplifier circuit, and an A / D conversion circuit connected in sequence, and the data transmission system includes a Bluetooth module or an ANT+ module.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] 1. This claw-type power data detector, through the setting of an aluminum alloy main structure and an ABS shell wrapped around the surface of the main structure, as well as waterproof measures such as waterproof potting grooves and waterproof sealing rings, effectively prevents water from entering the detector and causing short circuits or damage. This improves the detector's waterproofness, enabling it to work normally in humid or rainy environments, avoiding water intrusion that could affect the detector's accuracy and extending its service life.

[0013] 2. This disc-type power data detector improves the accuracy and stability of the instrument by placing strain gauge sensors in specific stress areas of the main structure and using signal conditioning circuits and microprocessor units for processing and calculation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment of a claw-type power data detector includes a main structure 1 and a shell 2. The shell 2 is wrapped around the outer surface of the main structure 1. The main structure 1 has a battery compartment 3 and a waterproof potting tank 4 inside. The battery compartment 3 contains a battery. The waterproof potting tank 4 contains a main board 5. The main board 5 has a strain gauge sensor 6, a signal conditioning circuit 7, a microprocessor unit 8, and a data transmission system 9. The strain gauge sensor 6, the signal conditioning circuit 7, the microprocessor unit 8, and the data transmission system 9 are electrically connected.

[0021] The claw-type power data detector has an input section 14 in the middle and output sections 15 around its perimeter. The main structure 1 is made of high-strength aluminum alloy, which has excellent mechanical properties and corrosion resistance. The outer surface of the main structure 1 is covered with a shell 2 made of ABS. The ABS shell 2 has good toughness and impact resistance, which can effectively protect the main structure 1 from external damage. At the same time, the ABS shell 2 also has a certain degree of waterproof performance, which can prevent water from entering the detector to a certain extent. In order to improve the waterproof performance of the detector, this utility model has a design that combines the main structure 1 and the shell... A waterproof sealing ring 16 is set between the main body structure 1 and the outer shell 2. The waterproof sealing ring 16 is made of a high-elasticity material, which has good sealing performance and aging resistance. It can effectively prevent moisture from entering the detector from the gap between the main body structure 1 and the outer shell 2. In order to improve the waterproof performance of the main board 5, the battery is installed in the battery compartment 3, and the main board 5 is installed in the waterproof potting groove 4. The waterproof potting groove 4 is filled with waterproof potting glue. The waterproof potting glue has good insulation and waterproof performance, which can effectively prevent moisture from entering the main board 5 and causing short circuits or damage, thereby avoiding the corrosion of electronic components by moisture and improving service life.

[0022] To improve the accuracy and stability of the detector, the strain gauge sensor 6 is attached to the position of the main structure 1 where the stress is greatest, so as to ensure that the deformation during the riding process can be accurately detected. At the same time, an adhesive is used to ensure that the strain gauge sensor 6 is firmly and reliably bonded to the main structure 1, so as to prevent it from falling off or loosening during the riding process.

[0023] The strain gauge sensor 6 is used to detect the deformation of the main structure 1 during cycling. The strain gauge sensor 6 can convert the deformation into an electrical signal output, which is proportional to the degree of deformation. The signal conditioning circuit 7 is used to amplify, filter, and linearize the electrical signal output by the strain gauge sensor 6 to improve the accuracy and stability of the signal. The microprocessor unit 8 is used to receive the signal output by the strain gauge sensor 6 and perform data processing. The microprocessor unit 8 can calculate cycling data such as power and cadence according to a preset algorithm. The data transmission system 9 is used to wirelessly transmit the cycling data calculated by the motherboard 5 to external devices, such as smartphones, tablets, or bicycle speedometers. The data transmission system 9 includes a Bluetooth module or an ANT+ module. Both of these modules have high transmission speed and stability and can meet the real-time transmission requirements of cycling data. Users can choose the appropriate wireless transmission method according to their needs and view and analyze the cycling data through the corresponding application.

[0024] The battery compartment 3 is used to install a rechargeable lithium battery. The battery compartment 3 is equipped with a charging interface for connecting an external power source to charge the battery. To improve the ease of use and convenience of the tester, this utility model also includes a display screen 10 and buttons 11. The display screen 10 is used to display cycling data and related information, such as power, cadence, and battery level. The buttons 11 are used to set the parameters and functions of the tester, such as selecting the wireless transmission method and calibrating the sensor. Both the display screen 10 and the buttons 11 are located on the outer casing 2 of the tester for easy operation and viewing by the user.

[0025] In summary, this claw-type power data detector, through the use of an aluminum alloy main structure 1 and an ABS shell 2 covering the surface of the main structure 1, as well as waterproof measures such as a waterproof potting groove 4 and a waterproof sealing ring 16, effectively prevents water from entering the detector and causing short circuits or damage. This improves the detector's waterproofness, enabling it to operate normally in humid or rainy environments, avoiding water intrusion that could affect the detector's accuracy, and extending its service life.

[0026] Furthermore, by placing the strain gauge sensor 6 in a specific stress area of ​​the main structure 1, and by using the signal conditioning circuit 7 and the microprocessor unit 8 for processing and calculation, the accuracy and stability of the detector are improved. This enables the detector to more accurately measure data such as power and cadence during cycling, providing athletes with more reliable training feedback.
