Description

Technical Field

[0001] The present application relates to the field of bicycles, and in particular to an intelligent fitness bicycle. Background Art

[0002] Currently, bicycles use chains as a transmission source. By stepping on the pedals, the chain drives the wheels to rotate, and ultimately drives the bicycle forward. It is a green and environmentally friendly means of transportation.

[0003] In the related art, a Chinese patent with authorization publication number CN205998081U discloses a bicycle with a closed chain drive formed by a chain, including a second flywheel, a third flywheel, a pulley, a guide wheel, and a transmission rope. When riding, the transmission rope is pulled by the reciprocating motion of the pedals, and the second flywheel or the third flywheel drives the first rotating shaft, and then the motion is transmitted to the first flywheel through the sprocket, thereby driving the rear wheel to rotate and realize the forward movement of the bicycle.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there is a problem: since the chain transmission has poor transmission smoothness, it is easy to produce a sense of frustration when riding, which in turn leads to reduced stability of the vehicle when riding, resulting in certain safety hazards when riding. Summary of the Invention

[0014] The following is combined with Figure 1-4 This application is described in further detail.

[0015] The embodiment of the present application discloses a smart fitness bicycle. Figure 1The smart fitness bicycle includes a frame 1, with a front wheel 2 rotatably mounted at the front end of the frame 1 and a rear motor wheel 3 rotatably mounted at the rear end of the frame 1. Also mounted on the frame 1 are pedals 4, a pedal motor 5, and a battery 6 located between the front wheel 2 and the rear motor wheel 3. The battery 6 is electrically connected to the rear motor wheel 3 and is used to power the rear motor wheel 3. The power output from the battery 6 to the rear motor wheel 3 thereby enables the rear motor wheel 3 to rotate.

[0016] like Figure 1 As shown, the bicycle frame 1 includes a main frame 11, and the pedals 4 are rotatably mounted on the main frame 11. The output shaft of the pedal motor 5 is linked to the rotation axis of the pedals 4, and the pedals 4 and the pedal motor 5 are electrically connected. The pedal motor 5 is electrically connected to a torque sensor and a Hall sensor. When the user rotates the output shaft of the pedal motor 5 by stepping on the pedals 4, the torque sensor and the Hall sensor can detect the speed of the pedal motor 5 and the force applied by the pedals 4 to the output shaft of the pedal motor 5.

[0017] like Figure 1 As shown, the main frame 11 also houses a vehicle controller electrically connected to the battery 6 and the power supply circuit for the rear motor wheel 3. When a user pedals the pedals 4 to rotate the output shaft of the pedal motor 5, the torque sensor and Hall effect sensor convert the collected data on the speed of the pedal motor 5 and the force applied to the pedals 4 into a transmission signal, which is then output to the vehicle controller. The vehicle controller then analyzes and processes the received transmission signal and outputs a corresponding control signal to control the power level received by the rear motor wheel 3. In this embodiment, the vehicle controller outputs a control signal of a corresponding magnitude based on the pulse width of the received transmission signal to control the power level input from the battery 6 to the rear motor wheel 3. This allows the vehicle to be used like a bicycle, eliminating the mechanical transmission mechanisms of conventional bicycles, such as chain drive, shaft drive, and synchronous belt drive, thereby significantly improving riding stability and reducing the incidence of mechanical failures. Furthermore, the pedaling force is not fed back by the wheels, making it more adaptable to various road conditions and slopes.

[0018] like Figure 1As shown, the vehicle frame 1 also includes a faucet handle 12 installed at the front end of the main frame 11, and the faucet handle 12 is located directly above the front wheel 2. A folding mechanism 9 is provided between the lower end of the faucet handle 12 and the main frame 11. The folding mechanism 9 includes a folding joint provided at the lower end of the faucet handle 12, a riser folding joint provided on the main frame 11, and a fastener for locking the folding joint and the riser folding joint. By loosening the fastener, the connection between the faucet handle 12 and the main frame 11 can be folded, which facilitates the storage of the vehicle body. A speed control handle 7 is rotatably installed on the faucet handle 12, and the speed control handle 7 is electrically connected to the vehicle controller. By rotating the speed control handle 7, the speed control handle 7 will output a corresponding speed control signal according to the angle of rotation. The speed control signal is specifically output as a voltage value of corresponding magnitude. When the vehicle controller receives the speed control signal output by the speed control knob 7, it outputs a corresponding control signal based on the magnitude of the speed control signal to regulate the power output from the battery 6 to the rear motor wheel 3, thereby adjusting the speed and torque of the rear motor wheel 3. Under the control of the speed control knob 7, the vehicle can be used as an electric vehicle. The handlebar 12 can also be equipped with pushbutton switches or touch switches, one set of switches for controlling the signal on and off between the pedal motor 5 and the battery 6, while the other set of switches for controlling the signal on and off between the speed control knob 7 and the battery 6. This allows the vehicle to switch between bicycle mode and electric vehicle mode. By turning the speed control knob 7, the speed control knob 7 outputs the speed control signal to the vehicle controller, which ultimately regulates the power output from the battery to the rear motor wheel 3. The configuration of the speed control knob 7 allows the vehicle to switch from bicycle mode to electric vehicle mode, thereby meeting the different riding needs of users. When the vehicle is switched to electric vehicle mode, driving is more labor-saving and convenient.

[0019] like Figure 1 As shown, the frame 1 also includes a seat frame 13 mounted at the rear end of the main frame 11. A taillight 14 is provided at the end of the seat frame 13 facing away from the front handlebar 12. The taillight 14 is electrically connected to the battery 6. The taillight 14 is powered by the battery 6 and can serve as a warning to vehicles behind, thereby improving the safety of the user when riding at night. A spring shock absorber 15 is installed between the seat frame 13 and the main frame 11, located below the taillight 14. One end of the spring shock absorber 15 is connected to the seat frame 13, and the other end of the spring shock absorber 15 is connected to the main frame 11. When the vehicle is traveling on a bumpy road, the spring shock absorber 15 can provide a shock-absorbing and buffering effect, thereby improving the riding comfort of the seat frame 13.

[0020] like Figure 2 、 Figure 3As shown, in order to facilitate the user's footsteps, a pedal 16 located between the faucet handle 12 and the seat frame 13 can also be installed on the main frame 11, and the pedal 16 is arranged at the bottom of the main frame 11. An arc-shaped mounting groove 161 facing the bottom of the main frame 11 is formed at the center of the upper surface of the pedal 16. The center of the pedal 16 is embedded in the main frame 11 through the mounting groove 161, and the inner side wall of the mounting groove 161 fits with the bottom wall of the main frame 11. The pedal 16 is tightened and fixed to the main frame 11 by bolts. The two ends of the pedal 16 extend from the bottom of the main frame 11 and can be placed on the user's feet. By raising the user's foothold, the comfort of riding can be improved, and when passing through a flooded section of road, it can reduce the splashing of water on the road onto the user's shoes.

[0021] like Figure 1 As shown, the upper end surface of the main frame 11 is provided with a storage frame 17 located between the handlebar 12 and the seat frame 13. The bottom of the storage frame 17 is removably mounted to the main frame 11 via bolts. A storage cavity 171 with an open top is formed within the storage frame 17. The upper end opening of the storage cavity 171 is inclined downward from the handlebar 12 toward the seat frame 13. A lifting handle 172 is also fixedly mounted on the outer wall of the storage frame 17. The lifting handle 172 is arched and its upper end extends beyond the upper end of the opening of the storage cavity 171. When the user is out and about, the storage frame 17 can meet the user's storage needs while riding.

[0022] like Figure 2 、 Figure 3 As shown, in order to meet the riding needs of children, the present application also provides a child riding mode, including a child seat 18 arranged between the handlebar handle 12 and the seat cushion frame 13. When the user needs to carry a child, the storage frame 17 is first removed from the main frame 11, and then the bottom of the child seat 18 is screwed to the main frame 11 by bolts, so that the child's riding needs can be met. The child seat 18 is installed above the pedal 16. When driving, the user can clamp the riding child by placing his feet on the pedal 16, thereby improving the safety of the child while driving. An armrest 181 for the child to support is fixedly installed on one end of the child seat 18 facing the handlebar handle 12. The armrest 181 is set so that when the child is riding, he can hold the armrest 181 with both hands, thereby further improving the safety of the child when riding.

[0023] like Figure 1 、 Figure 4As shown, the intelligent fitness bicycle also includes a support assembly 8, which includes a base 81 and two connectors 82 integrally formed on the base 81. The connectors 82 are symmetrically arranged on the left and right sides of the upper surface of the base 81. The two connectors 82 and the upper surface of the base 81 together form a receiving cavity 83 for inserting the rear motor wheel 3. The upper ends of the connectors 82 are provided with retaining grooves 821 facing the receiving cavity 83, and the two retaining grooves 821 are arranged opposite each other. The outer wall of the main frame 11 located at the rear motor wheel 3 is provided with insertion rods facing the retaining grooves 821. The main frame 11 is inserted into the respective retaining grooves 821 through the insertion rods. At this time, the rear motor wheel 3 is elevated by the action of the support assembly 8, and a gap is formed between the lower end of the rear motor wheel 3 and the upper surface of the base 81, and the rear motor wheel 3 is suspended. Under the action of the support assembly 8, the rear motor wheel 3 can be raised. Since there is a gap between the lower end of the rear motor wheel 3 and the base 81, the bicycle can be switched to indoor mode at this time. In indoor mode, the bicycle is a fitness exercise bike, and the user can meet the user's exercise and fitness needs by stepping on the pedals 4.

[0024] The operating principle of an intelligent fitness bicycle according to an embodiment of the present application is as follows: When a user is riding, the pedals 4 drive the output shaft of the pedal motor 5 to rotate. The torque sensor and Hall effect sensor provided on the pedal motor 5 can detect the speed and force of the user's pedaling. The torque sensor and Hall effect sensor convert the detected physical quantities into transmission signals and transmit them to the vehicle controller. After receiving the transmission signals, the vehicle controller processes the transmission signals and finally outputs corresponding control signals to the rear motor wheel 3 to control and adjust the speed and torque of the rear motor wheel 3. This application eliminates the mechanical transmissions such as chain drive, shaft drive, and synchronous belt drive of traditional bicycles, thereby greatly improving the stability of the bicycle during riding and reducing the incidence of mechanical failures of the vehicle. Furthermore, the pedaling force is not affected by wheel feedback, making it more adaptable to various road conditions and slopes. The torque of the pedal motor 5 can also be adjusted by the vehicle controller to meet the riding needs of different users. The setting of the speed regulating handle 7 can realize switching the vehicle from bicycle mode to electric vehicle mode, thereby meeting different riding needs of users. When the vehicle is switched to electric vehicle mode, driving can be more labor-saving and convenient.

[0025] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
