Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1 to Fig. 3, Fig. 1 is the block schematic diagram that the present invention exempts from the velocity indicating device with battery; Fig. 2 is the structural representation that the present invention exempts from the velocity indicating device with battery; Fig. 3 is the schematic diagram that the present invention exempts to be arranged at the velocity indicating device of battery on exercycle.As shown in Figure 1 to Figure 3, of the present invention exempting from comprises with the velocity indicating device of battery: magnet 10, induction coil 30, rectification amplification and drive circuit 50 and indicating device 60.Magnet 10 is arranged on the wheel shaft 20 of exercycle 1.Induction coil 30 is arranged on the wheel 40 of 1 exercycle, and wheel 40 is arranged in wheel shaft 20 (see Fig. 2) and rotates relative to wheel shaft 20.Rectification amplification and drive circuit 50 to be arranged on wheel 40 and to be electrically connected induction coil 30.Indicating device 60 to be arranged on wheel 40 and to be electrically connected rectification amplification and drive circuit 50.When wheel 40 rotates, induction coil 30 rotates relative to magnet 10 and magnetic field is changed and produces induced-current, induced-current is rectified into direct current and amplifies direct current by rectification amplification and drive circuit 50 again, sends instruction corresponding to wheel 40 velocity of rotation to order about indicating device 60.
In velocity indicating device of exempting from battery of the present invention, exercycle 1 can be trampled along with user due to wheel 40 and rotate, the induction coil 30 be arranged on wheel 40 therefore can be driven to rotate relative to wheel shaft 20.Due to induction coil 30 along with user tramples exercycle 1 and relative to the magnet rotors be arranged on wheel shaft 20, therefore the magnetic field of induction coil 30 can change and generate induced-current.By this, the induced-current generated can provide indicating device 60 required electric power to originate through rectification amplification and drive circuit 50 again.
In velocity indicating device of exempting from battery of the present invention, indicating device 60 can be such as LED light, but is not limited to this.Further, the quantity set of LED light is a plurality of by the visual actual demand of user, but is not limited to this.
In the embodiment exempted from the velocity indicating device of battery of the present invention, indicating device 60 (being such as LED light) may correspond to the velocity of rotation in wheel 40 and sends the different instruction of color.For example, when the rotating speed of wheel 40 is slower, the color that indicating device 60 sends can be such as green.Along with the rotating speed of wheel 40 is cumulative, indicating device 60 along with the color indicated by the rotating speed change of wheel 40, such as, from green yellowing, then can become red.Therefore, the color that user can send by indicating device 60 judges that user drives the speed of exercycle 1.
In another embodiment exempted from the velocity indicating device of battery of the present invention, indicating device 60 (being such as LED light) sends the different instruction of brightness corresponding to the velocity of rotation of wheel 40.For example, when the rotating speed of wheel 40 is slower, the instruction brightness that indicating device 60 sends is comparatively dark, and along with the rotating speed of wheel 40 cumulative, indicating device 60 can along with the rotating speed of wheel 40 change indicated by brightness, such as brightness is bright from being secretly incremented to.Therefore, the instruction brightness that user can send by indicating device 60 judges that user drives the speed of exercycle 1.
In addition, the quantity due to indicating device 60 can be a plurality of, therefore, indicating device 60 send instruction quantity also can correspond to the velocity of rotation of wheel 40.In other words, if when the rotating speed of wheel 40 is slower, the quantity that can send the indicating device 60 of instruction can be 1, and along with the rotating speed of wheel 40 cumulative, the quantity that can send the indicating device 60 of instruction can increase, such as, send instruction from only having an indicating device 60 to send to be indicated to three indicating devices 60.Therefore, by the quantity of the indicating device 60 sending instruction, user can judge that user drives the speed of exercycle 1.
In sum, velocity indicating device of exempting from battery of the present invention, the induced-current that can produce by induction coil, after rectification is amplified, can drive the indicating device be arranged on wheel to send instruction corresponding to faster rotating wheel, reaches the object of display exercycle rotating speed.Further, not only can provide the function of the driving situa-tion of supervising user self, user's music adjustment of also can arranging in pairs or groups drives speed, and by the rotating speed of indicating device display exercycle, and reaches and coordinate music and have abundant visual experience.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
