Description

Technical Field

[0001] The invention relates to the technical field of bicycles, and in particular to a device for collecting force parameters of bicycle riding. Background Art

[0002] In order to improve the cycling effect, we scanned the athletes and bicycles in 3D, optimized the design using 3D modeling software, established a 3D geometric model library of bicycles using computer-aided design technology, and manufactured bicycle models. We used wind tunnel tests to measure the wind resistance of the riding posture of the rider and the bicycle, and finally performed CFD calculations based on the wind tunnel results to obtain the corresponding database.

[0003] When riding a bicycle model, it can only detect the driving data when it is moving forward, but cannot detect the force data of the bicycle when the bicycle contacts the ground when the bicycle is bumping up and downhill. Therefore, a bicycle riding force parameter collection device is proposed to facilitate the collection of the force data of the bicycle when the bicycle is bumping up and downhill, thereby improving the convenience of collection. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a bicycle riding force parameter collection device, which is convenient for collecting the force data of the bicycle when the bicycle is subjected to large bumps up and down hills.

[0005] The technical solution adopted by the present invention to solve its technical problem is a bicycle riding force parameter collection device, which includes a bicycle model body, a pedal sensor installed on the pedal, a handlebar sensor installed on the handlebar, and a seat sensor installed on the seat. Two groups of connecting blocks are connected below the bicycle model body, and a horizontally arranged detection plate is fixedly connected to the lower end of the connecting block. A ramp simulation structure is provided below the detection plate, and a multi-stage slope adjustment structure is provided inside the ramp simulation structure. After the detection plate falls, it contacts the multi-stage slope adjustment structure. A driving structure is provided on the outer side of the ramp simulation structure, and the driving structure is used to push the detection plate to move upward.

[0006] By adopting the above technical solution, when collecting bicycle riding data, the rider sits on the seat on the main body of the bicycle model, holds the handlebars and steps on the pedals, so as to simulate the state of the bicycle when riding on a flat road, and cooperates with the pedal sensor, the handlebar sensor and the seat sensor to collect the force data of the bicycle model when riding on a flat road;

[0007] When it is necessary to simulate the bicycle's large uphill and downhill bumps, the angle of the multi-level slope adjustment structure is adjusted to a suitable position to simulate the road slope when going uphill and downhill. After the angle adjustment is completed, the rider relies on the ramp simulation structure to make the detection plate fall during the riding process. When the detection plate falls, it drives the main body of the bicycle model to move down synchronously. When the detection plate falls to a certain position, the detection plate collides with the multi-level slope adjustment structure to simulate the force data of the bicycle when the bicycle goes uphill and downhill. At the same time, the pedal sensor, handlebar sensor and seat sensor are used to collect the force data of the main body of the bicycle model to improve the convenience of collection.

[0008] In order to simulate the different amplitudes of bumps of the bicycle, the driving structure is used to drive the detection plate to reset and move upward. When the detection plate is reset and moved upward, it drives the multi-level slope adjustment structure to move up to a certain position. When the multi-level slope adjustment structure moves up to a certain position, the multi-level slope adjustment structure is separated from the detection plate. As the driving structure continues to drive the detection plate to reset and move up to the initial state, the detection plate is dropped again. When the detection plate falls, it collides with the multi-level slope adjustment structure again, so as to collect the force data of the bicycle model body colliding with the multi-level slope adjustment structure at different heights.

[0009] Specifically, the ramp simulation structure includes a frame, a plurality of groups of elastic support members are provided inside the frame, the detection plate is located above the plurality of elastic support members, a plurality of groups of electric pins are provided at the edge of the detection plate, and the initial state of the electric pins is located on the upper surface of the elastic support members.

[0010] By adopting the above technical solution, the rider sits on the seat on the main body of the bicycle model to simulate the normal state of riding. When it is necessary to collect the force data of the bicycle when it is bumping up and downhill, the electric pin rod is turned off to shorten the electric pin rod. When the electric pin rod is shortened, it no longer contacts the upper surface of the elastic support member. At this time, the detection plate falls in the frame. After the detection plate falls to a certain position, it collides with the multi-stage slope adjustment structure, so as to facilitate the collection of the force data of the bicycle and improve the convenience of collection.

[0011] After one collection is completed, the detection plate is driven to move up by the driving structure. After the detection plate moves up to a certain position, the electric pin squeezes the elastic support part and deforms it, then passes over the elastic support part and is located on the upper part of the elastic support part again. At this time, the detection plate returns to its initial state, and it is convenient to carry out the next set of force data detection.

[0012] Specifically, the multi-stage slope adjustment structure includes multiple groups of guide structures arranged on the inner wall of the frame, the guide structure includes several groups of vertical grooves distributed along the inclined direction, adjacent vertical grooves are connected by downwardly inclined oblique grooves, the depths of the vertical grooves are all shallower from bottom to top, the upper part of the vertical groove coincides with the upper part of the oblique groove, the depth of the upper part of the vertical groove is less than the depth of the upper part of the oblique groove, and the depth of the lower part of the vertical groove is greater than the depth of the lower part of the oblique groove, and several groups of vertical grooves are respectively slidably connected with horizontally arranged sliding rods and telescopic pins, the sliding rod is located below the rear part of the bicycle model body, and the telescopic pin is located below the front part of the bicycle model body, a horizontally arranged adjustment plate is provided above the sliding rod and the telescopic pin, one side of the adjustment plate is fixedly connected to the sliding rod, and a side of the adjustment plate away from the sliding rod is provided with an angle adjustment structure, and the angle adjustment structure is fixedly connected to one side of the telescopic pin.

[0013] By adopting the above technical solution, the angle of the adjustment plate is adjusted by the angle adjustment structure, and the angle of the adjustment plate is adjusted to a suitable position to simulate the slope of the road surface that the bicycle hits when it bumps; after the angle adjustment is completed, the rider sits on the seat on the main body of the bicycle model to simulate the normal state when riding; when it is necessary to collect the force data of the bicycle when it bumps greatly, the electric pin rod is turned off, so that the detection plate falls and hits the adjustment plate, so as to facilitate the collection of the force data of the bicycle;

[0014] When a set of force data is collected, the detection plate is driven to reset and move upward by the driving structure. When the detection plate is reset and moved upward, the adjustment plate is driven to move upward synchronously. When the adjustment plate moves upward, the telescopic pin and the slide bar are driven to move upward in the vertical slot. When the telescopic pin moves up to a certain position in the vertical slot, the depth of the vertical slot changes from deep to shallow from bottom to top, so that the telescopic pin is compressed. When the slide bar and the telescopic pin move to a certain position in the vertical slot, the slide bar and the telescopic pin enter the inclined slot. At this time, the detection plate cannot drive the adjustment plate to continue to move upward. Then the detection plate is separated from the adjustment plate, and the slide bar and the telescopic pin slide downward in the inclined slot. and enters the next set of vertical slots; when the driving structure drives the detection plate to reset and move upward to the initial state, the electric pin rod is closed again, so that the detection plate falls and collides with the adjustment plate, and the force data is collected again, thereby completing the secondary force data collection. After the secondary data collection, the adjustment plate, the slide bar and the telescopic pin are driven upward in the vertical slot by the detection plate again moving upward, so as to facilitate the subsequent collection of the next set of force data. By adjusting the height between the detection plate and the adjustment plate, the force data of the bicycle model body colliding with the multi-stage slope adjustment structure at different heights can be collected.

[0015] Specifically, a magnet is disposed on the lower surface of the detection plate, and the adjustment plate is magnetically affinity, and after the detection plate is lowered, the magnet is magnetically adsorbed to the upper surface of the adjustment plate.

[0016] By adopting the above technical solution, when a set of force data is collected, the detection plate is driven to reset and move upward by the driving structure, and the adjustment plate is driven to move upward synchronously by the magnet when the detection plate is reset and moved upward. After the adjustment plate moves up to a certain position, the slide bar and the telescopic pin enter the inclined slot. At this time, the detection plate can no longer drive the adjustment plate to move upward, and as the driving structure continues to drive the detection plate to move upward, the magnet is no longer magnetically adsorbed to the upper surface of the adjustment plate. When the detection plate is reset to the initial state, secondary force data collection can be performed, and this facilitates the collection of force data of the bicycle model body colliding with the multi-stage slope adjustment structure at different heights;

[0017] It should be pointed out that after all the force data have been collected, the bicycle model body and the detection plate can be removed, and the telescopic pin can be manually shortened to reset the adjustment plate and the slide rod telescopic pin to the initial state, which is convenient for the subsequent force data collection of the bicycle model body.

[0018] Specifically, the angle adjustment structure includes an arc plate fixedly connected to one side of the telescopic pin, the arc plate is provided with a plurality of groups of first positioning holes, the outer side of the adjustment plate close to the arc plate is provided with a plurality of groups of second positioning holes, positioning pins are installed in the second positioning holes, and the arc plate is fixedly connected to the adjustment plate through the positioning pins.

[0019] By adopting the above technical solution, when the angle of the adjustment plate needs to be adjusted according to actual use requirements, one side of the adjustment plate is lifted to a suitable angle, at which time the adjustment plate is tilted, and then the positioning pin is inserted into the first positioning hole and the second positioning hole, and the adjustment plate is fixed by the positioning pin, so as to complete the angle position of the adjustment plate, simulating the road slope when going uphill or downhill;

[0020] Before adjusting the inclination angle of the adjustment plate through the angle adjustment structure, the telescopic pins and sliding rods on both sides of the adjustment plate can be respectively inserted into vertical slots of different heights to quickly adjust the inclination angle of the adjustment plate, thereby realizing the forward or backward adjustment of the adjustment plate, thereby simulating the slope of the road surface hit by the bumps of the bicycle, and then adjusting the curved plate through the angle adjustment structure to improve the accuracy of the angle adjustment of the adjustment plate.

[0021] Specifically, the driving structure includes an electric hydraulic telescopic rod symmetrically arranged on the outside of the frame, the output end of the electric hydraulic telescopic rod is fixedly connected to a horizontally arranged connecting rod, both ends of the connecting rod are fixedly connected to a lifting rod, and a positioning groove is provided on the outside of the frame. One end of the lifting rod away from the connecting rod passes through the positioning groove and is located in the frame. After the lifting rod moves upward, it is squeezed and contacted with the lower surface of the detection plate.

[0022] By adopting the above technical solution, when the detection plate falls and collides with the adjustment plate to complete the force data collection, the electric hydraulic telescopic rod is used to drive the connecting rod and the lifting rod to move upward. When the lifting rod moves upward, it is squeezed and contacted with the lower surface of the detection plate, and thereby drives the detection plate to reset and move upward. When the detection plate is reset and moved upward to the initial state, the electric pin rod is located above the elastic support member. At this time, the electric hydraulic telescopic rod drives the connecting rod and the lifting rod to reset and move downward to the initial state, so that the detection plate can fall again and collide with the adjustment plate to collect force data.

[0023] Specifically, the elastic support member includes a positioning rod, and a support rod arranged at one end of the positioning rod close to the inner side of the frame, the upper edge of the support rod is hinged to the positioning rod through an elastic hinge shaft, the end face of the support rod close to the positioning rod is in extrusion contact with the end face of the positioning rod, and the frame is provided with a plurality of groups of vertically distributed pin holes, the pin holes are horizontally penetrated, and one end of the positioning rod passes through the pin holes and is located inside the frame.

[0024] By adopting the above technical solution, the support rod is supported by inserting the positioning rod into the corresponding pin hole, and the position of the elastic support member is adjusted at the same time. When the electric pin rod is reset and moved upward, the support rod will be squeezed to make the support rod swing upward. After the electric pin rod passes over the support rod, the support rod is automatically reset by relying on the elastic hinge shaft, so as to facilitate the upward reset of the detection plate; after the position adjustment of the elastic support member is completed, the angle of the detection plate will change. When the angle of the detection plate changes, when the detection plate falls, it can simulate the tilting state of the bicycle when the bicycle is greatly bumped, thereby facilitating the collection of force data of the bicycle model.

[0025] Specifically, the frame is provided with an opening corresponding to the arc-shaped plate.

[0026] By adopting the above technical solution, the angle position of the adjustment plate can be manually adjusted by relying on the opening, thereby improving the convenience of angle adjustment.

[0027] Beneficial effects of the present invention:

DETAILED DESCRIPTION

[0046] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0047] In order to facilitate the detection of the force data of the bicycle when the bicycle is subjected to a large bump up and down the slope, as an embodiment of the present invention, Figure 1 , Figure 2 As shown, a bicycle riding force parameter acquisition device described in the present invention includes a bicycle model body 1, a pedal sensor 2 installed on the pedal, a handlebar sensor 3 installed on the handlebar, and a seat sensor 4 installed on the seat. Two groups of connecting blocks 5 are connected below the bicycle model body 1, and a horizontally arranged detection plate 6 is fixedly connected to the lower end of the connecting block 5. A ramp simulation structure is provided below the detection plate 6, and a multi-stage slope adjustment structure is provided inside the ramp simulation structure. After the detection plate 6 falls, it contacts the multi-stage slope adjustment structure, and a driving structure is provided on the outer side of the ramp simulation structure, and the driving structure is used to push the detection plate 6 to move upward.

[0048] When in use, when collecting bicycle riding data, the rider sits on the seat of the bicycle model body 1, holds the handlebars and steps on the pedals, so as to simulate the state of the bicycle when riding on a flat road, and cooperates with the pedal sensor 2, the handlebar sensor 3 and the seat sensor 4 to collect the force data of the bicycle model when riding on a flat road;

[0049] When it is necessary to simulate the large bumps of the bicycle going up and downhill, the angle of the multi-level slope adjustment structure is adjusted to a suitable position to simulate the road slope when going up and downhill. After the angle adjustment is completed, the rider relies on the ramp simulation structure to make the detection plate 6 fall during the riding process. When the detection plate 6 falls, it drives the bicycle model body 1 to move down synchronously. When the detection plate 6 falls to a certain position, the detection plate 6 collides with the multi-level slope adjustment structure to simulate the force data of the bicycle when the bicycle goes up and downhill. At the same time, the pedal sensor 2, the handlebar sensor 3 and the seat sensor 4 are used to collect the force data of the bicycle model body 1 to improve the convenience of collection.

[0050] In order to simulate the different amplitudes of bumps of a bicycle, the driving structure is used to drive the detection plate 6 to reset and move upward. When the detection plate 6 resets and moves upward, it drives the multi-level slope adjustment structure to move up to a certain position. When the multi-level slope adjustment structure moves up to a certain position, the multi-level slope adjustment structure is separated from the detection plate 6. As the driving structure continues to drive the detection plate 6 to reset and move upward to the initial state, the detection plate 6 falls again. When the detection plate 6 falls, it collides with the multi-level slope adjustment structure again, so as to collect the force data of the bicycle model body 1 colliding with the multi-level slope adjustment structure at different heights.

[0051] In order to facilitate the detection of the falling plate 6, exemplary, as Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes that the ramp simulation structure includes a frame 7, a plurality of groups of elastic support members are provided on the inner side of the frame 7, the detection plate 6 is located above the plurality of groups of elastic support members, a plurality of groups of electric pin rods 8 are provided on the edge of the detection plate 6, and the initial state of the electric pin rods 8 is located on the upper surface of the elastic support members.

[0052] When in use, the rider sits on the seat on the bicycle model body 1 to simulate the normal state of riding. When it is necessary to collect the force data of the bicycle when it is bumping up and downhill, the electric pin rod 8 is turned off to shorten the electric pin rod 8. When the electric pin rod 8 is shortened, it no longer contacts the upper surface of the elastic support member. At this time, the detection plate 6 falls in the frame 7. After the detection plate 6 falls to a certain position, it collides with the multi-stage slope adjustment structure, so as to facilitate the collection of the force data of the bicycle and improve the convenience of collection.

[0053] After one collection is completed, the detection plate 6 is driven upward by the driving structure. After the detection plate 6 moves to a certain position, the electric pin rod 8 squeezes the elastic support member and deforms it, then passes over the elastic support member and is located on the upper part of the elastic support member again. At this time, the detection plate 6 returns to its initial state, and it is convenient to carry out the next set of force data detection.

[0054] In order to facilitate the collection of force data of the bicycle model body 1 colliding with the multi-level slope adjustment structure at different heights, for example, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the present invention also includes that the multi-stage slope adjustment structure includes multiple groups of guide structures arranged on the inner wall of the frame 7, the guide structure includes several groups of vertical grooves 9 distributed along the inclined direction, adjacent vertical grooves 9 are connected by downwardly inclined inclined grooves 10, the depth of the vertical grooves 9 is from deep to shallow from bottom to top, the upper part of the vertical groove 9 coincides with the upper part of the inclined groove 10, the depth of the upper part of the vertical groove 9 is less than the depth of the upper part of the inclined groove 10, and the depth of the lower part of the vertical groove 9 is greater than the depth of the lower part of the inclined groove 10, and several groups of the vertical grooves 9 are respectively slidably connected with horizontally arranged sliding rods 11 and telescopic pins 12, the sliding rod 11 is located below the rear part of the bicycle model body 1, and the telescopic pin 12 is located below the front part of the bicycle model body 1, and a horizontally arranged adjustment plate 13 is provided above the sliding rod 11 and the telescopic pin 12, one side of the adjustment plate 13 is fixedly connected to the sliding rod 11, and the side of the adjustment plate 13 away from the sliding rod 11 is provided with an angle adjustment structure, and the angle adjustment structure is fixedly connected to one side of the telescopic pin 12.

[0055] When in use, the angle of the adjusting plate 13 is adjusted by the angle adjustment structure, and the angle of the adjusting plate 13 is adjusted to a suitable position to simulate the slope of the road surface that the bicycle hits when it bumps; after the angle adjustment is completed, the rider sits on the seat on the bicycle model body 1 to simulate the normal state when riding; when it is necessary to collect the force data of the bicycle when it bumps greatly, the electric pin rod 8 is turned off, so that the detection plate 6 falls and hits the adjusting plate 13, so as to facilitate the collection of the force data of the bicycle;

[0056] When a set of force data is collected, the detection plate 6 is driven to reset and move upward by the driving structure. When the detection plate 6 is reset and moved upward, the adjustment plate 13 is driven to move upward synchronously. When the adjustment plate 13 moves upward, the telescopic pin 12 and the slide bar 11 are driven to move upward in the vertical slot 9. When the telescopic pin 12 moves up to a certain position in the vertical slot 9, the depth of the vertical slot 9 changes from deep to shallow from bottom to top, so that the telescopic pin 12 is compressed; when the slide bar 11 and the telescopic pin 12 move to a certain position on the vertical slot 9, the slide bar 11 and the telescopic pin 12 enter the inclined slot 10, and the detection plate 6 cannot drive the adjustment plate 13 to continue to move upward. Then the detection plate 6 is separated from the adjustment plate 13, and the slide bar 11 and the telescopic pin 1 2 slides downward in the inclined slot 10 and enters the next set of vertical slots 9; when the driving structure drives the detection plate 6 to reset and move upward to the initial state, the electric pin rod 8 is closed again, so that the detection plate 6 falls and collides with the adjustment plate 13, and the force data is collected again, thereby completing the secondary force data collection. After the secondary data collection, the adjustment plate 13, the slide bar 11 and the telescopic pin 12 are driven to move upward in the vertical slot 9 by the detection plate 6 again, so as to facilitate the subsequent collection of the next set of force data. By adjusting the height between the detection plate 6 and the adjustment plate 13, it is convenient to collect the force data of the bicycle model body 1 colliding with the multi-stage slope adjustment structure at different heights.

[0057] In order to facilitate the upward movement of the adjustment plate 13, for example, Figure 7 , Figure 8 , Fig. 9 As shown, the present invention also includes that a magnet 14 is provided on the lower surface of the detection plate 6, and the adjustment plate 13 is magnetically affinity, and after the detection plate 6 falls, the magnet 14 is magnetically adsorbed to the upper surface of the adjustment plate 13.

[0058] When in use, after a set of force data collection is completed, the detection plate 6 is driven to reset and move upward by the driving structure. When the detection plate 6 is reset and moved upward, the adjustment plate 13 is driven to move upward synchronously by the magnet 14. After the adjustment plate 13 moves up to a certain position, the slide bar 11 and the telescopic pin 12 enter the inclined slot 10. At this time, the detection plate 6 cannot continue to drive the adjustment plate 13 to move upward, and as the driving structure continues to drive the detection plate 6 to move upward, the magnet 14 is no longer magnetically adsorbed to the upper surface of the adjustment plate 13. When the detection plate 6 is reset to the initial state, secondary force data collection can be performed, and this facilitates the collection of force data of the bicycle model body 1 colliding with the multi-stage slope adjustment structure at different heights;

[0059] It should be pointed out that after all the force data have been collected, the bicycle model body 1 and the detection plate 6 can be removed, and the telescopic pin 12 can be manually shortened, so that the adjustment plate 13, the slide rod 11 and the telescopic pin 12 can be reset to the initial state, which is convenient for the subsequent force data collection of the bicycle model body 1.

[0060] In order to facilitate the angle adjustment of the adjustment plate 13, for example, Figure 2 , Figure 4 , Fig.10 , Fig.11 As shown, the present invention also includes that the angle adjustment structure includes an arc plate 15 fixedly connected to one side of the telescopic pin, and a plurality of groups of first positioning holes 16 are provided on the arc plate 15, and a plurality of groups of second positioning holes are provided on the outer side of the adjustment plate 13 close to the arc plate 15, and a positioning pin 17 is installed in the second positioning hole, and the arc plate 15 is fixedly connected to the adjustment plate 13 through the positioning pin 17.

[0061] When in use, according to actual use needs, when the angle of the adjustment plate 13 needs to be adjusted, one side of the adjustment plate 13 is lifted to a suitable angle, at which time the adjustment plate 13 is tilted, and then the positioning pin 17 is inserted into the first positioning hole 16 and the second positioning hole, and the adjustment plate 13 is fixed by the positioning pin 17, so as to complete the angle position of the adjustment plate 13, simulating the road slope when going up and down the slope;

[0062] Before adjusting the inclination angle of the adjustment plate 13 through the angle adjustment structure, the telescopic pins 12 and the slide bars 11 on both sides of the adjustment plate 13 can be respectively inserted into the vertical slots 9 at different heights, so as to quickly adjust the inclination angle of the adjustment plate 13 and realize the forward or backward adjustment of the adjustment plate 13, thereby simulating the slope of the road surface hit by the bumps of the bicycle, and then adjusting the curved plate 15 through the angle adjustment structure to improve the accuracy of the angle adjustment of the adjustment plate 13.

[0063] In order to facilitate the detection plate 6 to reset and move upward, for example, Figure 1 , Figure 2 , Figure 8 , Fig. 9 As shown, the present invention also includes that the driving structure includes an electric hydraulic telescopic rod 18 symmetrically arranged on the outside of the frame 7, the output end of the electric hydraulic telescopic rod 18 is fixedly connected to a horizontally arranged connecting rod 19, both ends of the connecting rod 19 are fixedly connected to a lifting rod 20, and the outside of the frame 7 is provided with a positioning groove 21 extending through it, and one end of the lifting rod 20 away from the connecting rod 19 passes through the positioning groove 21 and is located in the frame 7, and the lifting rod 20 is pressed and contacted with the lower surface of the detection plate 6 after moving up.

[0064] During use, when the detection plate 6 falls and collides with the adjustment plate 13 to complete the force data collection, the electric hydraulic telescopic rod 18 drives the connecting rod 19 and the lifting rod 20 to move upward. When the lifting rod 20 moves upward, it is squeezed and contacted with the lower surface of the detection plate 6, and thereby drives the detection plate 6 to reset and move upward. When the detection plate 6 resets and moves upward to the initial state, the electric pin rod 8 is located above the elastic support member. At this time, the electric hydraulic telescopic rod 18 drives the connecting rod 19 and the lifting rod 20 to reset and move downward to the initial state, so that the detection plate 6 falls again and collides with the adjustment plate 13 to collect force data.

[0065] In order to facilitate the adjustment of the angle of the detection plate 6, for example, Figure 1 , Figure 3 , Figure 5 , Fig.11 , Fig.12 As shown, the present invention also includes that the elastic support member includes a positioning rod 24, and a support rod 25 arranged at one end of the positioning rod 24 close to the inner side of the frame 7, the upper edge of the support rod 25 is hinged to the positioning rod 24 through an elastic hinge shaft 22, and the end face of the support rod 25 close to the positioning rod 24 is in extrusion contact with the end face of the positioning rod 24, and a plurality of groups of vertically distributed pin holes 23 are provided on the frame 7, and the pin holes 23 are horizontally penetrated, and one end of the positioning rod 24 passes through the pin hole 23 and is located on the inner side of the frame 7.

[0066] When in use, the support rod 25 is supported by inserting the positioning rod 24 into the corresponding pin hole 23, and the position of the elastic support is adjusted at the same time. When the electric pin rod 8 is reset and moved upward, the support rod 25 will be squeezed to make the support rod 25 swing upward. After the electric pin rod 8 passes over the support rod 25, the support rod 25 is automatically reset by relying on the elastic hinge shaft 22, so as to facilitate the upward reset of the detection plate 6; after the position adjustment of the elastic support is completed, the angle of the detection plate 6 will change. When the angle of the detection plate 6 changes, when the detection plate 6 falls, it can simulate the tilting state of the bicycle when the bicycle is greatly bumpy, thereby facilitating the force data collection of the bicycle model.

[0067] For example, Figure 1 As shown, the present invention also includes that the frame 7 is provided with an opening 26 corresponding to the arc-shaped plate 15 .

[0068] When in use, the opening 26 can be used to manually adjust the angle position of the adjustment plate 13, thereby improving the convenience of angle adjustment.

[0069] When the present invention is used, when collecting bicycle riding data, the rider sits on the seat of the bicycle model body 1, holds the handlebars and steps on the pedals, so as to simulate the state of the bicycle when riding on a flat road, and cooperates with the pedal sensor 2, the handlebar sensor 3 and the seat sensor 4 to collect the force data of the bicycle model when riding on a flat road;

[0070] When it is necessary to simulate a large uphill and downhill bumping of the bicycle, the telescopic pins 12 and the slide bar 11 on both sides of the adjustment plate 13 are first inserted into the vertical slots 9 at different heights, so as to quickly adjust the inclination angle of the adjustment plate 13, and adjust the forward or backward inclination of the adjustment plate 13, thereby simulating the slope of the road surface hit by the bumping of the bicycle, and then lift one side of the adjustment plate 13 to a suitable angle. At this time, the adjustment plate 13 is tilted, and then the positioning pin 17 is inserted into the first positioning hole 16 and the second positioning hole, and the adjustment plate 13 is fixed by the positioning pin 17, so as to complete the angle position of the adjustment plate 13, simulate the road surface slope when going uphill and downhill, and improve the accuracy of the angle adjustment of the adjustment plate 13;

[0071] The rider sits on the seat of the bicycle model body 1 to simulate the normal state of riding; when it is necessary to collect the force data of the bicycle being greatly bumped, the electric pin 8 is turned off to make the detection plate 6 fall and collide with the adjustment plate 13, so as to facilitate the collection of the force data of the bicycle;

[0072] When a group of force data is collected, the detection plate 6 is driven to reset and move upward by relying on the electric hydraulic telescopic rod 18, the connecting rod 19 and the lifting rod 20. When the detection plate 6 is reset and moved upward, the adjustment plate 13 is driven to move upward synchronously by relying on the magnet 14. When the adjustment plate 13 moves upward, it drives the telescopic pin 12 and the slide bar 11 to move upward in the vertical slot 9. When the telescopic pin 12 moves up to a certain position in the vertical slot 9, the depth of the vertical slot 9 changes from deep to shallow from bottom to top, so that the telescopic pin 12 is compressed; when the slide bar 11 and the telescopic pin 12 move to a certain position on the vertical slot 9, the slide bar 11 and the telescopic pin 12 enter the inclined slot 10, and the detection plate 6 cannot drive the adjustment plate 13 to continue to move upward, and then the detection plate 6 is separated from the adjustment plate 13, and the slide bar 11 and the telescopic pin 12 slide downward in the inclined slot 10 and enter the next group of vertical slots 9; when the electric hydraulic telescopic rod 18 brings After the dynamic detection plate 6 and the electric pin rod 8 are reset and moved up to a certain position, the electric pin rod 8 will squeeze the support rod 25, so that the support rod 25 swings upward. After the electric pin rod 8 passes over the support rod 25, the support rod 25 automatically resets by relying on the elastic hinge shaft 22, so as to facilitate the upward movement of the detection plate 6 to reset to the initial state, and then the electric pin rod 8 is closed again, so that the detection plate 6 falls and collides with the adjustment plate 13, and the force data is collected again, so as to complete the secondary force data collection. After the secondary data collection, the adjustment plate 13, the slide bar 11 and the telescopic pin 12 are moved upward in the vertical slot 9 by relying on the upward movement of the detection plate 6 again, so as to facilitate the subsequent collection of the next set of force data. By adjusting the height between the detection plate 6 and the adjustment plate 13, it is convenient to collect the force data of the bicycle model body 1 colliding with the multi-stage slope adjustment structure at different heights;

[0073] The support rod 25 is supported by inserting the positioning rod 24 into the corresponding pin hole 23, and the position of the support rod 25 is adjusted at the same time. After the position adjustment of the support rod 25 is completed, the angle of the detection plate 6 will change. When the angle of the detection plate 6 changes, when the detection plate 6 falls, it can simulate the tilting state of the bicycle when the bicycle is greatly bumped, thereby facilitating the force data collection of the bicycle model.
