Abstract

The utility model relates to a remote control speed limiter for motor vehicles, which belongs to the field of automatic speed control of the motor vehicles, and comprises an emitter that can emit speed-reducing signal, a receive that can receive the speed-reducing signal, an electric motor and a metering valve. When the motor vehicles enter speed-limiting road sections, the receiver can drive the electric motor to adjust the oil mass of the metering valve, so that the speed of the vehicles can be adjusted within specified speed. When the motor vehicles drive out of the speed-limiting road sections, the speed-limiting action can be automatically removed. The utility model has the advantages of low cost and high safety, achieves the requirement of limiting speed fundamentally and actively, and is suitable for the motor vehicles to limit speed through remote control.

Description

Motor vehicle remote speed limited attachment

The remote control of motor vehicle speed-limit device is a kind of device that self-propelled vehicle is carried out the remote control speed limit, belongs to the motor vehicle speed automation field.

At present, limiting the method that vehicle travels in regulation highway section speed limit both at home and abroad is to erect stated-speed sign, reminds the chaufeur speed limit.Corresponding cooperation means are traffic administration personnel with the velometer overspeed situation that checks vehicles.This method can not solve the overspeed of vehicle problem of travelling at all.Owing to drive over the speed limit, accident takes place again and again, all brings great harm to national wealth and life safety.

The purpose of the present utility model is to overcome the defective of prior art, fundamentally solves the speed limit problem, makes self-propelled vehicle enter the speed limit state automatically when entering the speed limit highway section, can remove the speed limit effect voluntarily again when rolling the speed limit highway section away from.

For realizing goal of the invention, scheme of the present utility model is by radio or infrared or hypracoustic send mode, restricting signal is sent in the regulation highway section, make the vehicle that this device is installed after receiving signal, press the semaphore request pushing motor, adjust the oil mass of limit fuel tap, the speed of a motor vehicle is adjusted in the speed of regulation.This device is made up of projector, receptor, motor, limit fuel tap.Projector sends restricting signal by radio or infrared or hypracoustic send mode in the regulation highway section.Projector can be installed on the pole in regulation highway section also can make hand-held design, is held in traffic police's hand.Receptor receives behind the restricting signal that projector sends through regularly driving the relay work that makes on the motor, relay tip adhesive motor forward rotation.The mistake oil mass of motor rotational angle adjustment limit fuel tap, thus realize the speed limit purpose.When receptor receive that projector sends separate limited signal after, motor oppositely forwards zero to, the limit fuel tap is all opened, no longer speed limit.Receptor, motor, limit fuel tap all are installed on the self-propelled vehicle.

Below in conjunction with drawings and Examples the utility model is done further and carefully to be stated.

Fig. 1 is the utility model wireless transmitter circuits figure.

Fig. 2 is the utility model wireless receiver circuits figure.M is a motor.

Fig. 3 is the utility model limit fuel tap structural representation:

1 is oil outlet pipe, and 2 is oil inlet, and 3 is spindle, the 4 fuel tap bodies that exceed, and 5 is barrier film, and 6 is the flexible axle head, and 7 is flexible shaft protecting, and 8 is the flexible axle core, 9 is jam nut.

The utility model is an example with wireless launcher and wireless receiver.When vehicle entered the speed limit highway section, the projector that is installed in initial place, speed limit highway section did not stop issuing the pulse encoding (Fig. 1) of tetrad modulation.IC ₁Be 555 time base circuits, IC ₂Be 4017 pulse distributors, IC ₃Be emitter, IC ₄For BA1404 modulate emission sheet, launch wireless signal by antenna.When receptor by receiving wire and IC ₅Receive special-purpose sheet TDA7000 and receive (Fig. 2) behind the restricting signal, the elimination high-frequency signal is delivered to counting machine IC with signal ₆In 4518, behind the counting signal delivered to decoder IC ₈In 4028, decoder is sent into latch IC after signal is confirmed ₇, IC ₁₂In 4502, (decoder can overlappingly use, expansion way), latch one group of signal after, no longer accept same signal (prevent to receive repeatedly same signal, repeatedly export enabling signal) and then by timer IC ₉0400 rear drive IC ₁₃4538 actions are opened the source switch on the motor, driver IC ₁₁Work, relay J ₂Action, the angle that the motor forward rotation is stipulated is adjusted the mistake oil mass of limit fuel tap, thereby realizes speed limit.When receptor was received the ring off signal that projector sends here, receptor was delivered to counting machine with signal, delivered to behind the counting in the decoder, and decoder is sent into latch after signal is confirmed, makes driver IC by timer then ₃4583 actions, its process is opened electric power switch as previously mentioned, driver IC ₁₄Work, relay J ₁Action, motor then oppositely forward zero to, and the limit fuel tap is all opened, no longer speed limit.IC ₅Adopt TDA7000, IC ₆Be 4518, IC ₇, IC ₁₂Be 4502, IC ₈Be 4028IC ₉Be 0400, IC ₁₀, IC ₁₅, IC ₁₆Be 4078, IC ₁₁, IC ₁₃, IC ₁₄Be 4538, IC ₁₇Be 4013.Motor is selected the 12V direct-flow micromachine for use.

The 8. available steel wire strand of flexible axle core of limit fuel tap (Fig. 3) is made, and it links to each other with motor, has flexible shaft protecting 7. in its outside, has flexible axle head that half circular metal material makes 6. in its lower end.Have the barrier film that the elastomeric material of rib shape makes and 5. seal up the 4. first half of limit fuel tap body.Limit fuel tap body can be made also available metal with plastics and make.Spindle is connected on the barrier film with rubber pad, and 3. the spindle on the barrier film is made by metallic material and is shaped as cone, inserts in the oil outlet pipe oil pipe hole 1., and oil outlet pipe and valve body are connected with jam nut as fine setting, can be according to the oil pipe adjustment of different inner diameters.1. oil outlet pipe is connected with the oil pipe that leads to carburettor, and 2. oil inlet links to each other with the fuel tank oil pipe.When the motor forward rotation, flexible axle is rotated in the forward, and the flexible axle head promotes downwards along screw thread, and the spindle on the barrier film adjusts oil mass to the action of oil outlet pipe direction.When the motor backward rotation, flexible axle counter-rotating, spindle is with the diaphragm of rubber reposition, no longer the current limliting amount.The not only available flexible axle core of limit fuel tap drives motor and rotates also available gear or alternate manner transmission, makes motor rotate the purpose that drive limit fuel tap is adjusted oil mass to reach.

The utility model advantage is when vehicle enters the speed limit location voluntarily speed limit. When rolling speed-limit road section away from, vehicle recovered not limit state in 5 seconds. Avoid the human negligence general idea, drive over the speed limit, fundamentally realized on one's own initiative the speed limit requirement. This installation cost is low, and good reliability is applicable to the use of remote control of motor vehicle speed limit.
