In the pedal device of the present invention, the variable crank 30 may be made of an elastic material, such as rubber, an electromagnetic spring, an air bag, etc., or may be a telescopic structure, such as a telescopic rod, etc., and the present invention is not limited thereto. The variable crank 30 is connected to the transmission and the personalized stop 40, respectively, during use, and since the shape of the personalized stop 40 is based on the user's personal information and ergonomics, typically non-circular, during riding, the variable crank 30 changes length and/or angle during movement.
The variable crank 30 may include an electromagnetic spring, and further include a control chip, wherein the magnitude and direction of the elastic force of the electromagnetic spring are controlled by controlling the current of the electromagnetic spring, so that the variable crank 30 changes the length and/or angle during the movement. For example: when the current passing through the electromagnetic spring is in the positive direction, the elastic force generated by the electromagnetic spring is positive pressure, and the elastic force increases along with the increase of the current and decreases along with the decrease of the current; when the current passing through the electromagnetic spring is in a negative direction, the elastic force generated by the electromagnetic spring is reverse pulling force, and the pulling force is increased along with the increase of the current and is reduced along with the decrease of the current. The variable crank 30 can adjust the control chip through the keys arranged on the variable crank to control the magnitude and direction of the elastic force of the electromagnetic spring, and can be controlled by remote control through a mobile phone and other devices, and the invention is not limited.

In the present invention, the airbag may be a single-layer airbag or a multi-layer airbag. The air pump can generate air in a chemical mode or an electric mode, and the invention is not limited.
In the present invention, the variable crank 30 may be formed by combining different materials. For example: the parts connected with the transmission device and the personalized limiting device 40 at the two ends are made of rigid materials such as metal and alloy, and the middle part is made of elastic materials such as rubber, electromagnetic springs and air bags, so that the connection between the variable crank 30 and the transmission device and the personalized limiting device 40 is prevented from being influenced by the elastic materials in the using process, and the connection between the variable crank 30 and the transmission device and the personalized limiting device 40 is further prevented from being influenced. The two ends of the variable crank 30 can be made of rigid materials, the middle part of the variable crank is divided into a plurality of sections, and the rigid materials and the elastic materials are alternately made, so that one section of rigid materials can be clamped between the elastic materials at the two ends, and the situation that the deformation amplitude is too large in the using process and the user is influenced when the variable crank 30 is made of the elastic materials can be avoided.
The pedal device of the invention comprises 2 variable cranks and 2 individualized limit devices at the left and right, which are respectively suitable for the left leg and the right leg of a user. The left and right 2 variable cranks and the 2 individualized limit devices may be the same or different according to the actual situation of the user. For example: the lengths, muscle strength, postures and the like of the left leg and the right leg of the user are not completely the same, so the pedaling motion routes which are obtained by analyzing the user information and the pedaling motion model and are suitable for the left leg and the right leg of the user are not necessarily the same, and therefore, the left variable crank and the right variable crank and the 2 personalized limiting devices can be different. To better suit the user, the left and right 2 variable cranks and the 2 individualized position-limiting devices of the footrest device of the present invention may be identical or different.
The pedaling apparatus of the present invention may further comprise a pedal plate coupled to the variable crank 30. The footrest also allows the distance of the footrest from the median plane to be varied while the user is riding by varying the length and/or angle of the variable crank 30 under the limits of the personalized stop 40. The median plane is a tangent plane at the middle of the bicycle in the left-right direction. This allows different distances between the user's feet or between the foot pedals to be set at different locations. For example: through controlling individualized stop device's shape, can make the distance between the high point user both feet of riding and ride the distance difference between the low point user both feet, more accord with user's use.
The pedal device, the personalized stop device 40, of the present invention may be manufactured by 3D printing technology, or may be manufactured by other suitable means. The three-dimensional (3D) printing technology is adopted for manufacturing, so that the personalized requirements of users can be effectively met, the mold opening cost is saved, and the cost is reduced.
In the pedal device, the personalized limiting device 40 is replaceable, and different personalized limiting devices 40 suitable for users can be adopted according to different users.
