Detailed Description
The foregoing and other technical matters, features and effects of the present invention will be described in detail with reference to the accompanying drawings 1 to 5.
Embodiment 1, a system for judging road conditions and performing intelligent speed change according to pedaling force of a bicycle, includes a bicycle body 1, a front chain wheel 7, a rear chain wheel 8, a chain 9, and pedals 6, as shown in fig. 5, since the above components are all the prior art, the connection structure thereof is not described much here), and the following detailed description is made for the improvement of the present solution, and the specific process is as follows:
a pressure monitoring module is arranged in a pedal 6 on a vehicle body 1 and is electrically connected with a control terminal 2 arranged on the vehicle body 1, the vehicle body 1 is respectively provided with a front speed changer, a rear speed changer, a front speed changer and a rear speed changer, the front speed changer and the rear speed changer are respectively matched with a front gear disc 7 and a rear gear disc 8, the speed changing module 5 is electrically connected with the control terminal 2, the pressure monitoring module arranged on the pedal 6 monitors the treading force of a rider on the pedal 6 in real time in the riding process and transmits the monitored treading force to the control terminal 2 in real time, the control terminal 2 judges a received treading force signal according to a set program and sends a speed changing instruction (changes according to the magnitude of the treading force of the rider) to the speed changing module 5 according to the judgment result, so that the road condition of the position of the rider at the moment can be judged, i.e., ascending slope or descending slope or level road), so as to respectively control the actions of the front derailleur and the rear derailleur through the speed changing module 5, i.e., to make the front derailleur and the rear derailleur cooperate with each other so as to adjust the position of the chain 9 relative to the front fluted disc 7 and the rear fluted disc 8, thereby achieving the effect of speed changing of the bicycle;
the specific judgment process is as follows:
when a rider does not change the speed, the pedal 6 is correspondingly changed by the pedaling force of the rider according to the road condition, and when the rider rides the speed-changing bicycle to climb the slope, if the pedaling frequency (the pedaling frequency: the number of turns of the pedal within one minute) is kept unchanged, the slope of the climbing slope is larger, and the bicycle pedal 6 is needed to be pedaled by larger force (the pressure signal monitored by the pressure monitoring module is larger);
if the pedaling frequency (pedaling frequency: the number of turns of the pedaling within one minute) is kept unchanged, the larger the gradient of the downhill is, the less force is needed to pedal the bicycle pedal 6, and the less the force is applied to the bicycle pedal 6 (the smaller the pressure signal detected by the pressure monitoring module is);
when a rider rides the variable speed bicycle to run on flat ground, if the traveling speed of the bicycle is required to be kept constant, the bicycle pedal 6 is required to be pedaled with constant force under the condition of keeping the pedalling frequency (the pedalling frequency: the number of turns of the pedal within one minute);
if the pitch circle diameter of the tooth sheets 10 on the front toothed disc 7 wound by the chain 9 is larger, and the pitch circle diameter of the tooth sheets 10 on the rear toothed disc 8 wound by the chain 9 is smaller, the treading for one circle is more laborious, the running distance for one circle is lengthened, and the device is suitable for the road condition and the violent movement mode of a downhill section;
if the pitch circle diameter of the teeth 10 on the front toothed disc 7 wound by the chain 9 is smaller, and the pitch circle diameter of the teeth 10 on the rear toothed disc 8 wound by the chain 9 is larger, the treading time is more labor-saving, the treading distance is shortened, and the variable speed bicycle is suitable for road conditions and slight motion modes of uphill road sections;
based on the above principle, the present scheme can determine the road condition in real time according to the magnitude of the pedaling force of the pedal 6 by the rider, firstly, it is set that the pedaling force of the rider (adult) on a road surface with a relatively flat terrain is a standard value (the standard value is an interval range), when the pressure monitoring module detects that the pressure signal exceeds the standard value within a certain range (it indicates that the road condition of the rider is in an uphill stage), the control terminal 2 sends a signal to the speed changing module 5 and the speed changing module 5 respectively controls the front transmission and the rear transmission to operate, so that the chain 9 matched with the rear toothed disc 8 moves and is matched with the toothed plate 10 with a relatively large diameter (i.e. is wound on the toothed plate 10 with a relatively large diameter), so that the chain 9 matched with the front toothed disc 7 moves and is matched with the toothed plate 10 with a relatively small diameter (i.e., winding the gear piece 10 with a smaller diameter), when the pressure monitoring module detects that the pressure signal is within the range of a standard value interval, the control terminal 2 sends a signal to the speed changing module 5 and controls the front speed changer and the rear speed changer to stop working;
when the pressure monitoring module detects that the pressure signal is lower than a standard value within a certain range (which indicates that the road condition of the rider is in a downhill stage), the control terminal 2 sends a signal to the speed changing module 5, and the speed changing module 5 respectively controls the front speed changer and the rear speed changer to operate, so that the chain 9 matched with the rear fluted disc 8 moves and is matched with the teeth 10 with a smaller diameter (namely, is wound on the teeth 10 with a smaller diameter), and the chain 9 matched with the front fluted disc 7 moves and is matched with the teeth 10 with a larger diameter (namely, is wound on the teeth 10 with a larger diameter);
through the cooperation of pressure monitoring module, control terminal 2, speed change module 5, preceding derailleur, back derailleur can realize riding passerby and realize the variable speed effect automatically according to the difference of road conditions at the in-process of riding for it removes the loaded down with trivial details of manual variable speed from to ride passerby, thereby ensure to ride passerby and have more energy to go to deal with the various circumstances of the in-process of riding, make the process of riding comparatively safe, reliable, also make to ride passerby and obtain better experience of riding.
