Description
" ELECTRONIC AUTOMATIC SYSTEM FOR DETECTION OF RELATIVE MOTION, AND SAFETY SIGNALING DEVICE FOR BICYCLES AND OTHER SMALL VEHICLES, USING THIS SYSTEM ".
This patent describes a new electronic automatic system specially conceived to detect a relative motion of two different objects, for instance the body and a moving shaft of a machine, using a magnetic generator which produces a AC electric tension with its basic components ( magnets and coils ) respectively on the shaft and on the body, this movement allowing to obtain an electric tension capable to light one or more light emitting diodes on a control panel or on a safety device.
This patent also refers to a new safety signaling device developed for bicycles and all kind of vehicles that don't have another electric source.
The motion detection systems known are relatively complex and expensive. They have a lot of different components and need preventive and corrective maintenance.
These equipment are very important for the control systems on many industrial plants, and on any other automatic apparatus.
By the other hand, automobiles and other vehicles need safety signaling devices, specially at night or when there is smog or other phenomena which reduces the visibility.
The automobiles and other vehicles equipped with combustion or electric engines have an electric source, allowing the use of safety lights.
In order to get a signal light on bicycles and other similar vehicles, we need to use a dynamo, a kind of electric generator which shaft is moved by contacting the pneumatic of the vehicle. This equipment is expensive, reduces the life of the tyre and demands from the user an additional work on the pedals.
As an alternative to the old dynamos, there are some safety light devices which have " leds " or a lamp, using a battery as a electric source. Unfortunately, the life of these sources are very short, needing replacement each few hours of operation.
The main object of this invention is to provide a very simple and inexpensive electronic automatic system to detect a relative motion of two different objects, which can be adapted to any kind of equipment for several
purposes, allowing the monitoring' and control of the relative motion of two different components of a machine or a system.
Another object of this patent is to describe a signaling system composed by only two basic components, specifically magnets and coils with ferromagnetic core.
A third object of this invention is to provide a safety apparatus for bicycles, tricycles and other similar vehicles, based on the system above mentioned.
Another object of this patent is to present a safety light apparatus mounted in a wheel of a bike, using the rotational motion of the wheel as a energy source, without any kind of friction that could become more difficult to the user the work on the pedals.
A fifth object of this invention is to show a similar apparatus, mounted on the gear wheel on the crank of the bicycle. The last object of this patent is to describe another assemblage, with the magnets and coils disposed inside the tube that involves the shaft of the pedal set.
The new electronic automatic system for detection of relative motion is composed by one or more pairs fo magnets, preferable of cilindrical shape, and by one or more tubular coils with ferromagnetic core ( usually named " solenoid coils ", or simply " solenoids " ), being these components attached to components or mechanical parts capable to present relative motion by each other. These motion can be tangential, axial, rectilineal, continuous or alternative, being essential that the coils, during this motion, cross the magnetic field of the magnets, the simectrical axis of each coil being permanently paralel to the correspondent axis of the referred magnets.
This system don't need batteries or other external source of energy. When a coil crosses the magnetic field of a magnet, a electric pulse is generated on the spires. The electric current obtained by a single pair coil/magnet is sufficient to generate electric pulses capable to light a " led ". The amount of electrial tension depends on the velocity of the coil through the magnetic field and the number of spires.
Even short motions, or motions at low velocities, can be detectedby this new system.
Obviously, we can have a system with more than one coil and/or magnet, allowing to get electric tension so high then we can light several leds. It allows to employ this system to make safety sgnaling apparatus for small vehicles, as bicycles, tricycles and others that don't have a battery or another source of electrical energy.
This new system has an electric circuit composed by a tubular coil with ferromagnetic core, the terminals of the spires being connected to the terminals of one or more leds, the coil being attached to a moving part of a machine, on a position which allows the coil to cross the magnetic field of the North or South pole of a magnet fastened to another part of the same machine, in order the coil and the magnet can describe a relative motion, allowing that axis of magnet and coil remain continuously parallel, no matter which is the relative position of these two components.
There are many possible ways to combine several magnets and coils. For instance, we can put the coils on a disc fastened to a shaft of a vehicle, while the coils can be attached to a fixed plate, the spires being connecteds to leds positioned on a pannel or display. In the case of bicycles and similar vehicles, we can get the energy for the apparatus using the motion of the wheels or of the gear. One of the components ( preferable the magnet ) can be attached to the shaft of a wheel, or to the crank, while the coil will be fastened to the fork of the same wheel, or to the tube which involves the crank shaft. An improvement of this assemblage employ a disc with a central hole, having some equidistant circular caves where we put cilind cal magnets, this disc being concentrically attached on a wheel of the bicycle, while some coils are inserted on correspondent recess on a shell, with the axis of its core being parallel to the axis of the magnets, this shell being fixed to the fork of the same wheel, allowing the coils be in front of the magnets when the wheel is moving, the same shell having one or more holes which receive leds connected to the spires of the coils or, in alternative, these leds being attached to another desired place of the bike.
Two different safety apparatus can be installed on a same bike, one on each wheel.
We can imagine several other possible assemblages for this apparatus, near the crank of pedals, being the magnets fastened on a disc fixed to the gear, and the coils being inserted on two pieces attached to the tube that involves the shaft of the crank.
The magnets may also be positionned inside this tube, fixed on a disk fastened to the rotary shaft, with the coils being fixed on holes on the wall of the same tube. For better understanding of the invention, the drawings referred below show the essential characteristics of the new system for detection of relative motion, and of some safety devices for bicycles based on the same technology:
