[0021] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, the utility model is a portable fitness monitor, including a monitor housing, in which a deformable body, a strain gauge 6 and a data main control component are arranged.

[0023] A deformable body is provided with a deformable portion and two mounting connection portions 31. The two mounting connection portions 31 are provided at both ends of the deformable portion. The mounting connection portions 31 at both ends can be cooperatively installed on fitness equipment. The strain gauge 6 is electrically connected to the data main control component, and the strain gauge 6 is pasted on the deformable body.

[0024] The mounting connection portion 31 is provided with a connection mounting hole.

[0025] The deformable body generates strain under the tensile force, and the strain gauge 6 expands and contracts along with the strain. The resistance of the strain gauge 6 changes accordingly, causing the voltage to change, generating an analog electrical signal, and at the same time transmitting the analog electrical signal to the data main control component.

[0026] The data master control component can cooperate with the strain gauge 6 to obtain fitness data information.

[0027] The fitness data can be effectively acquired through the cooperation between the deformable body and the strain gauge 6 .

[0028] The data main control component includes a power supply battery 4 and a control mainboard 5, on which a control module, a power supply module, a posture sensor module and a data processing module are arranged.

[0029] The control module is a microcontroller unit, namely MCU.

[0030] The data processing module includes a signal amplification module and a signal conversion module.

[0031] The posture sensing module is a posture sensor. When detecting its motion state, it obtains the identification signal, converts the signal into digital-to-analog format, and outputs a digital electrical signal, which can obtain the number of fitness cycles, the number of pull-ups, and other data. Typically, for example, a six-axis motion component, model MPU-6050, can be used to complete this function, but it is not limited to this component model.

[0032] The strain gauge 6 is a Wheatstone full-bridge strain gauge, and the material of the deformable body is metal.

[0033] The Wheatstone full-bridge strain gauge is attached to the deformable part of the deformable body of the metal structure. The deformable body is deformed by tension during installation and use. The Wheatstone full-bridge strain gauge expands and contracts with the deformation, and its resistance changes accordingly, causing a change in voltage and generating an analog electrical signal.

[0034] The signal amplification module is a signal amplification circuit.

[0035] The analog electrical signal is amplified by the signal amplification circuit, and the signal amplification module amplifies the analog electrical signal.

[0036] The amplified signal is converted into a digital electrical signal by the signal conversion module after a certain error interference signal filtering process. This signal has a certain linear relationship with the weight of the fitness equipment, such as the gantry fitness rack and the rowing fitness rack.

[0037] This relationship can be obtained through multiple measurements and calculations, and the tension data can be obtained from it.

[0038] The signal conversion module can typically use HX711 to complete this function. HX711 is a high-precision 24-bit A / D conversion chip that integrates a regulated power supply, an on-chip clock oscillator, and digital communication functions, but is not limited to this chip.

[0039] The control module is integrated with a Bluetooth communication module, which can establish a connection with other devices via Bluetooth and transmit data information wirelessly to other devices, such as mobile phones and tablets, for user viewing.

[0040] The Bluetooth communication module sends the detected fitness data to the Bluetooth paired host device, such as a mobile phone or a computer, for software collection, calculation and analysis. Here, a Bluetooth chip, model nrf52832 or nrf52840, can be used to achieve this function.

[0041] The control main board 5 is provided with a switch control 51 and a charging interface, and the housing of the monitor is provided with a mounting hole 11 that matches the switch control 51 and the charging interface.

[0042] The monitor housing comprises a monitor front housing 1 and a monitor rear housing 2 , and the monitor front housing 1 and the monitor rear housing 2 are snap-connected.

[0043] A hollow portion 33 is provided in the deformation portion, and the hollow portion 33 can increase the deformation degree of the deformation portion. At the same time, the hollow portion 33 can provide installation space for other components, such as the power supply battery 4 and the control motherboard 5, thereby improving the utilization rate of the space, compressing the volume of the product, and improving portability.

[0044] Reducing the area of ​​the deformation portion can effectively improve the deformation effect, so that the strain gauge 6 can more accurately and obviously identify the change in deformation.

[0045] The deformation part is two connecting rods 32, the two connecting rods 32 are symmetrically arranged, the hollow part 33 is a hollow gap arranged between the two connecting rods 32, the number of strain gauges 6 is two groups, the strain gauges 6 are fixedly arranged on the connecting rods 32, and the two groups of strain gauges 6 correspond one to one to the two connecting rods 32.

[0046] The connecting rod 32 is provided with a mounting groove 321 for the strain gauge 6 , and the mounting groove 321 can facilitate accurate mounting of the strain gauge 6 and prevent position offset from affecting the recognition effect.

[0047] Obviously, the number of strain gauges 6 can also be 1, 3, 4, etc. In this embodiment, two strain gauges 6 are used, which are respectively arranged on two connecting rods 32, and the two strain gauges 6 are respectively arranged on the front and rear sides of the connecting rod 32.

[0048] By setting up two strain gauges 6 , it is possible to continue to use when one of them fails, thereby ensuring the integrity of the functions, and the accuracy of data monitoring is improved by comparing and coordinating the signals of the two strain gauges 6 .

[0049] The connecting rod 32 is provided with a clearance groove 322 which cooperates with the housing of the monitor. The setting of the clearance groove 322 can facilitate the installation of the housing of the monitor and has a certain effect of positioning the housing of the monitor.

[0050] The present embodiment provides a test process of a portable fitness monitor as follows: The present embodiment provides a method for implementing fitness data monitoring compared to existing methods, and has the advantage of flexible use.

[0051] First, remove the buckle between the handle and the steel wire rope on the tension fitness equipment, install a portable fitness monitor provided by the utility model, and connect the connecting and mounting holes at both ends of the deformable main body to the handle and the steel wire rope respectively to realize the installation process of the product.

[0052] Toggle switch control 51 to start the product, and the mobile phone or computer searches and pairs.

[0053] The user pulls the handles of the fitness equipment to perform regular fitness movements.

[0054] During the pulling process, the pulling force will cause the deformable body to generate strain, and the strain gauge 6 will also generate strain, thereby causing the resistance value of the circuit in the strain gauge 6 to change, and the voltage of the strain gauge 6 will also change, generating a low-voltage analog electrical signal at the mV level.

[0055] The low voltage analog electrical signal is amplified by a certain multiple through the signal amplification circuit. The chip model HX711 used in the utility model can amplify the low voltage analog electrical signal by 128 times. Other chips of the same type can also be used. The signal is converted into a digital electrical signal through the signal conversion module using an analog-to-digital converter, i.e., ADC. The digital electrical signal has a certain linear proportional relationship with the actual load, and this linear relationship can be obtained by measuring different loads multiple times.

[0056] The posture sensor and the strain gauge 6 perform monitoring work at the same time to detect the movement posture, such as acceleration, movement change of a certain axis, total time of weight pulling up and other data. Other chips of the same type used in the utility model can also be used.

[0057] The relevant fitness status data is sent to the previously paired host device via the MCU's low-power Bluetooth.

[0058] The product can achieve the effect of real-time monitoring of fitness users during their fitness process.

[0059] From the above, it can be seen that the beneficial effect of the utility model is: the use of its mechanism can effectively solve the problem of poor flexibility in the existing technology for realizing fitness data information monitoring. By using this product, the strain gauge 6 can sense the strain of the deformable body, and cooperate with the data main control component to process the signal, so as to obtain fitness data. It can be flexibly installed on a variety of fitness equipment, has strong flexibility in use, effectively improves the user experience, and can meet the needs of fitness enthusiasts.
