bicycle

The present invention relates to a bicycle and, in particular, to a bicycle equipped with a bicycle shifting system.

In the past, in order to allow bicycles to overcome different terrains, such as hillsides or gravel roads, mechanisms to change the speed of advancement began to occur. After years of evolution, it has evolved from the traditional 14-speed to 22-speed, and even through the computer's electronic signal for variable speed control.

At present, the bicycles on the market, the front disc 2 speed and the rear disc 10 speed, through the manual manual control of the transmission has a total of 20 speed. In theory, the front and rear disk rotation ratio is calculated, 50T/12T=4.16, simply speaking, the front disk turns one turn, and the rear disk can turn four turns. However, from the calculation formula, it will be found that there will be an overlap area of the gyro ratio in the middle, as shown in the gray net at the bottom of Table 1.

The same is true for 50T/19T and 34T/13T. This makes it easy for manual manual control to create shifting confusion in these overlapping areas. Therefore, it is necessary to overcome this blind spot area through computer program calculation. But no matter how the shifting technology is improved, the bicycle shifting system will still be It is necessary to manually control the transmission by means of heavy manpower to change the speed of the vehicle.

In addition, the bicycle shifting system of the present invention may further include a portable mobile device equipped with the sensing device, and receiving the shifting parameter to upload the environmental variable and/or the shifting parameter to the cloud. Conversely, the portable mobile device of the present invention can of course receive another shift parameter and another environment variable, the other shift parameter and the other environment variable being shared by another user through the cloud. News. For example, another user can similarly upload a large amount of the environment variable and the shift parameter to the cloud, and the bicycle shifting system reloads a large amount of the environment variable and the shift parameter stored in the cloud, and the mass shift The post-analysis information is used to provide more precise shifting parameters for intelligent shifting purposes.

Referring to FIG. 1, a first embodiment of the present invention provides a bicycle 100 including a shifting line 1 coupled to a transmission and a bicycle shifting system 2. It is specifically stated that the shift control proposed by the prior art mostly replaces the existing Shimano shifting system, that is, another system is created, but this cannot be supported by most users, and the practice of the present invention is There is a bicycle shifting system on the Shimano transmission. On the shifting line 1, the Shimano transmission is characterized by smooth and fast shifting. In short, the bicycle shifting system 2 of the present invention is interposed on the shifting line 1 by the clamp 3.

Referring to FIG. 2, the bicycle shifting system 2 includes a sensing device 21, a microprocessor 22, a servo motor 23, and a system opening switch 24. The sensing device 21 senses environmental changes and issues an environmental variable. The microprocessor 22 analyzes and calculates the environmental variables and issues a shift parameter. The servo motor 23 is configured to tension or loosen the shift line 1 connected to the transmission according to the shift parameter, and to perform a shifting position on the transmission (not shown) to achieve shifting. The system opening switch 24 described above is used to activate the bicycle shifting system 2. In practical applications, the user can remotely control the above-mentioned system opening switch 24 to activate the bicycle shifting system 2. This principle is similar to the manual hand row switching on the car, and will not be repeated here. But what is specifically stated here is that the system The opening switch 24 is clamped on the shifting line 1. When the system opening switch 24 is not turned on, the shifting line 1 is not controlled by the bicycle shifting system 2, and the user can manually shift the speed manually, and the program can be recorded and learned through the program in the smart phone described later. The shifting habits of the person, in turn, reach the AI intelligent shift.

FIG. 2 of the present embodiment merely exemplifies a clipper 3 that is driven by a gear to be interposed on the shifting line 1, and performs a shifting position of the transmission (not shown) to achieve shifting, but has a general knowledge in the technical field of the present invention. It is to be understood that any equivalent variation that can drive the clamp 3 is within the scope of the present invention, such as by means of a chain that drives the clamp 3.

In the embodiment of the present invention, the sensing device 21 of the bicycle shifting system 2 is a nine-axis sensor. In addition, it is known to those skilled in the art that the sensing device 21 can also be replaced with a GPS sensor depending on actual design requirements. Through the GPS sensor, the automatic lifting and lowering action is carried out by the vehicle speed, which ensures that the starting position is in the lighter gear position, and after starting, the speed is gradually increased, and then the upshifting action is performed to accelerate. This method can simulate the shifting principle of a similar car, and the GPS sensor can also predict the upcoming ramp to shift.

In other embodiments, the sensing device 21 may also be a revolving speed sensor, which passes back the speed sensor (not shown) on the pedal of the bicycle, returns the data to the microprocessor 22, and controls the servo. The motor 23 allows the pedal to be rotated at a speed that is optimal for the user. For example, when the return speed increases, it automatically upshifts; on the contrary, when the return speed decreases, it automatically downshifts. Therefore, regardless of the flat road climbing, the speed of rotation is maintained at a high speed.
