Abstract
The utility model discloses an over-speed alarm of an electric bicycle, and belongs to speed limiting devices of transport tools. The over-speed alarm is composed of a magnet installation block, a reed pipe circuit, a triggering music chip, a power module and a horn. The magnet installation block is installed on a spoke of a front wheel of the electric bicycle, and the reed pipe circuit, the power module, the triggering music chip and the horn are fixedly installed on a front fork of the electric bicycle. When the electric bicycle is driven in an over-speed mode, the horn can give out continuous sound to prompt a rider. An over-speed alarm circuit is simple, high in reliability and low in cost, and continuous sound prompt can be given when the electric bicycle exceeds the speed.
Description
Technical field
The utility model relates to a kind of battery-driven car overspeed alarm, magnet, dry-reed tube, triggering musical film, loudspeaker are specifically adopted, adopt the principle of rotating object centnifugal force, and a kind of low cost, battery-driven car overspeed alarm simple in structure of structure belong to the velocity limiter field of the vehicle.
Background technology
Battery-driven car has become a kind of vehicle that in city, people are in daily use.But the shortcoming of battery-driven car is silent, accelerate soon, people just allow battery-driven car among high speed danger in moment unconsciously.Although there is now a lot of speed limiter for electric vehicles, but its principle is many based on the components and parts such as electro-optical tubes or hall device, then adopt complicated digital processing circuit, picking rate signal from the wheel of battery-driven car, after the processing of microprocessor, show, and after data compare, hypervelocity is pointed out.This mode be owing to must there being complicated digital circuit, the even digital processing device such as micro controller system, thereby cost is higher, and complicated circuit also easily breaks down and makes to test the speed and speed limit breaks down, and even do not work.Therefore, people are low in the urgent need to a kind of cost, battery-driven car speed-limit device simple in structure, but this device not at present.
Utility model content
For above-mentioned deficiency, the utility model provides a kind of battery-driven car overspeed alarm.
The utility model is achieved through the following technical solutions: a kind of battery-driven car overspeed alarm, formed by magnet mounting blocks, reed switch circuit, triggering Music Clip, power module, loudspeaker, magnet mounting blocks is contained on the spoke of front wheel of electric motorcar, reed switch circuit is fixedly mounted on battery-driven car front vehicle fork together with power module, triggering Music Clip, loudspeaker, in the time that battery-driven car exceeds the speed limit, loudspeaker can send lasting sound with prompting cyclist.
Described magnet mounting blocks is made up of protecgulum, base, guide rod, magnet piece, extension spring, mounting screw, two guide rods are arranged on the centre of base, magnet piece is through on two guide rods, can on guide rod, automatically slide, extension spring is through on guide rod, and one is fixed on base, one is fixed on magnet piece, upper cover can be held on base and seal, and has wheel spoke mounting hole on described base, and mounting screw is fixedly mounted on base on spoke by screw.
Described power module is converted to the power line voltage of battery-driven car to trigger the voltage that Music Clip, reed switch circuit, loudspeaker can be used.
Described reed switch circuit is used for the signal detection approaching to magnet piece, when have magnet piece near time, dry-reed tube will be connected, reed switch circuit will, to triggering energizing signal of music circuit, make to trigger Music Clip and sound.
Described triggering Music Clip is preferably the Music Clip that a triggering continued to sound in 3 seconds.
Described loudspeaker are used for sending the sound that triggers Music Clip.
The beneficial effect of this utility model is: applying centrifugal force principle, in the time that the speed of battery-driven car is higher, the centnifugal force that magnet piece is subject to is just larger, thereby be through the action that the magnet piece on guide rod has the pulling force that overcomes extension spring outwards to fly out, in the time that speed reaches certain value, leave the magnet piece of original position by the close dry-reed tube being arranged on car fork in the rotation of wheel, thereby make reed switch circuit conducting, give and trigger energizing signal of Music Clip, although the time of connecting containing reed pipe circuit is very short, but this circuit has sent a trigger signal pulse to triggering Music Clip, triggering Music Clip receives after start pulse signal, to loudspeaker send one long be the sound of 3 seconds, ultrafast with prompting rider speed, need to as early as possible the speed of a motor vehicle be lowered, after the speed of a motor vehicle lowers, the centnifugal force that magnet piece is subject to reduces, to move to original position direction, thereby leave the trigger position of dry-reed tube, reed switch circuit just cannot be connected again, after thereby the sound that triggering Music Clip once triggers finishes, do not broadcasting new acoustic segment, thereby playing the object of pointing out cyclist to note speed.
