DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 8 As shown, an embodiment of the present invention provides a multi-dimensional physical fitness detection machine for cycling sports and a detection method thereof, including a bracket 1, a bicycle body 2 fixed on the top of the bracket 1, the bicycle body 2 including a handlebar, a crossbeam, a front wheel, a seat, a transmission mechanism and a pedal, a physical fitness detection mechanism arranged on the bicycle body 2, an adjustable support rod 3 and a support sleeve 6 are respectively fixed on the crossbeam of the bicycle body 2, a telescopic hose 4 is fixedly connected to the top of the adjustable support rod 3, and a connected detection cover 5 is fixed at one end of the telescopic hose 4, the detection cover 5 includes a cover body 51 and a detection end 53, when the detection cover 5 is worn, the inhaled and exhaled gas is detected through the detection end 53, a cleaning component 7 is provided inside the support sleeve 6, an elastic trigger component 8 is provided in the detection cover 5, an airway switching part is fixed in the telescopic hose 4, and when the elastic trigger component 8 senses the inhaled and exhaled gas in the detection cover 5, the airway switching part opens the inhalation port and the exhalation port respectively.

[0037] Example 1: When in use, the tester rides on the bicycle body 2 and sits on the seat, holding the detection cover 5 and wearing it on the outside of the face, mouth and nose, then holding the handlebars with both hands and stepping on the pedals, starting the external detection terminal, and performing exercise movements. The heart rate detection module on the handlebars monitors the heart rate value, the pedal force detection module on the pedals monitors the pedaling pressure, and the cadence and speed detection module in the transmission system records the cadence and speed. As breathing movements are performed during exercise, when air is inhaled, a flowing airflow is generated inside the detection cover 5, and an instantaneous low pressure is formed in the detection cover 5, which causes the elastic trigger component to 8 elastic action, and triggers the electrical signal, so that the inhalation port in the airway switching part is opened, and the ambient air is inhaled into the detection cover 5, and the detection end 53 detects the amount of inhaled oxygen and carbon dioxide. As the gas is exhaled, the exhaled gas enters the detection cover 5, and an instantaneous high-pressure area is formed inside, so that the elastic trigger component 8 is reversely deformed and triggers the electrical signal. The external control terminal opens the exhalation port in the airway switching part, and the exhaled gas is quickly discharged to the environment. The exhaled gas and the inhaled gas are located in two different areas in the space, and the detection end 53 in the detection cover 5 detects the amount of oxygen and carbon dioxide in the exhaled gas.

[0038] First, by utilizing the cooperation of the detection cover 5 and the telescopic hose 4, during physical fitness testing, the inhaled and exhaled gases can be collected and tested by wearing the detection cover 5, and the oxygen consumption and carbon dioxide output during exercise can be calculated, and the respiratory quotient calculation can be completed, thereby comprehensively evaluating the aerobic exercise capacity, expanding the scope of physical fitness testing, and obtaining more comprehensive physical fitness testing data.

[0039] In addition, by utilizing the cooperation of the detection cover 5, the elastic trigger component 8 and the airway switching part, during the actual aerobic breathing exercise detection, the elastic trigger component 8 is used to identify the inhalation and exhalation actions, and the separate opening and closing of the inhalation air port and the exhalation air port in the airway switching part are controlled, ensuring that during the detection process, the exhalation airway and the inhalation airway are separated from each other, avoiding mutual contamination of the airways during the breathing process, ensuring the cleanliness of the inhalation airway, and improving the actual breathing accuracy. At the same time, the direction of the two groups of trachea 10 in the airway switching part is controlled to make the breathing direction different, avoiding the exhaled gas from being repeatedly inhaled, and relatively far away from and separating the breathing area, thereby ensuring the accuracy of breathing detection.

[0040] Embodiment 2: After the inspection is completed, the inspection cover 5 is held toward the cleaning assembly 7 and sleeved on the outer side of the cleaning sleeve 73 of the cleaning assembly 7. The motor 71 is started. The motor 71 drives the connecting plate 72 to rotate, and the cleaning sleeve 73 rotates in the cover body 51, frictionally cleaning the inner wall of the cover body 51 and the inspection end 53. As the output shaft of the motor 71 rotates, the sleeved cam 74 is driven to rotate, and when the cam 74 rotates, it intermittently squeezes and pushes the extrusion block 132 in the compression part 13, so that the extrusion block 132 moves along the inside of the fixed plate 131 through the spring 16 in the elastic mechanism. The annular elastic bag 121 in the disinfection component 12 is squeezed, so that when the annular elastic bag 121 is compressed, the disinfectant filled inside is sprayed out along the slit 122, and sprayed out along the through holes on the cleaning sleeve 73 and the connecting plate 72 in the cleaning component 7, so that the disinfectant water is filled in the cover body 51 and the inside of the cover body 51 is disinfected. The continuously sprayed disinfectant gas in the cover body 51 pushes the elastic trigger component 8 to operate and opens the trachea 10 for guiding out the exhaled air. The disinfectant is finally discharged along the telescopic hose 4 and the trachea 10 for exhalation, completing the synchronous disinfection of the trachea 10.

[0041] First, through the cooperation of the cleaning component 7, the disinfection component 12 and the compression part 13, the detection cover 5 is quickly cleaned after the physical fitness test, and the cleaning component 7 is used to mechanically cooperate with the compression part 13 and the disinfection component 12 to intermittently spray disinfectant liquid into the detection cover 5 during the rotation cleaning process, realizing mechanical friction cleaning while cooperating with disinfectant disinfection to complete the sanitary treatment after use, ensuring the hygienic safety of the detection cover 5, and the actual cleaning and disinfection operation is convenient and the use effect is good.

[0042] In addition, the elastic trigger component 8 is further utilized to guide the disinfectant into the airway switching part during cleaning and disinfection, and the interior is cleaned synchronously, especially the expiratory airway is fully disinfected, the use effect is good, and the hygiene and safety are further improved.

[0048] The elastic trigger component 8 deforms with inhalation and exhalation to respectively touch the trigger No. 1 and the trigger No. 2, and uses the induction under the touch to perform control identification to realize the independent opening and closing of the airway inlet and the exhalation outlet.

[0049] Among them, the airway switching part includes a support plate 9, an air pipe 10 and a control valve 11. The support plate 9 is fixedly sleeved in the telescopic hose 4.

The outer ends of the two air pipes 10 pass through the telescopic hose 4 and extend to the outside. The outer ends of the two air pipes 10 are far away from each other up and down.

[0050] The two trachea 10 form two different groups of airways with different directions, so that inhalation and exhalation are kept away from each other, thus avoiding interference and improving the accuracy of subsequent measurements.

[0051] Among them, the cleaning component 7 includes a motor 71, a connecting plate 72, a cleaning sleeve 73 and a cam 74.

[0052] The cleaning assembly 7 rotates to clean the interior of the detection cover 5 , thereby achieving a detection and cleaning process after use. The cam 74 reciprocates and squeezes the compression portion 13 during the rotation process.

[0053] Among them, the inner sleeve of the support sleeve 6 is provided with a disinfection component 12, and the inner side of the disinfection component 12 is provided with a compression part 13. When the cleaning component 7 rotates for cleaning, the compression part 13 is controlled to reciprocate and compress the disinfection component 12, and the disinfectant in the disinfection component 12 is sprayed out through the cleaning component 7. The disinfection component 12 includes an annular elastic bag 121 and a slit 122. The slit 122 is opened in the annular elastic bag 121, and the slit 122 is opened when the annular elastic bag 121 elastically expands. A connecting pipe is provided on the top of the support sleeve 6, and the connecting pipe is connected to the annular elastic bag 121. The through tube replenishes disinfectant into the annular elastic bag 121. The compression part 13 includes a fixed plate 131 and an extrusion block 132. The extrusion block 132 is elastically sleeved between the fixed plates 131 on both sides through an elastic mechanism. The fixed plate 131 is fixed in the support sleeve 6. The elastic mechanism includes an adapter 14, a side plate 15 and a spring 16. The adapter 14 is opened on the side of the extrusion block 132.

One end of the spring 16 is fixedly connected to the side plate 15, and the other end is fixed in the adapter 14.

[0054] After being compressed repeatedly, the compression portion 13 pushes the annular elastic bag 121 to be compressed, and sprays disinfectant water through the slit 122 to complete the disinfection process.

[0055] A detection method for a multi-dimensional physical fitness tester for cycling sports includes the following detection steps:

[0056] Step 1: The tester rides on the bicycle body 2 and sits on the seat, holding the detection cover 5 and wearing it on the outside of the face, mouth and nose. Then, he holds the handles with both hands, steps on the pedals, starts the external detection terminal, and performs exercise.

[0057] Step 2: The heart rate detection module on the handlebar monitors the heart rate value, the pedal force detection module on the pedal monitors the pedal pressure, and the cadence and speed detection module in the transmission system records the cadence and speed;

[0058] Step 3: As the person breathes during exercise, air is inhaled, generating an air flow inside the detection cover 5 and forming a transient low pressure inside the detection cover 5. This causes the elastic trigger assembly 8 to elastically actuate and trigger an electrical signal, opening the inlet port in the airway switching portion. This allows ambient air to be inhaled into the detection cover 5, and the detection end 53 detects the amount of inhaled oxygen and carbon dioxide.

[0059] Step 4: As the exhaled gas enters the detection cover 5, an instantaneous high-pressure area is formed inside, causing the elastic trigger component 8 to deform in the opposite direction and trigger an electrical signal.
