Abstract
The utility model relates to an automatic inflation control system for an automobile tire, which comprises laser range finders, an MCU (Micro Control Unit) control center, an inflator, a selector switch, a voice broadcast device and an inflation connecting device, wherein the laser range finders are installed in positions of a front axle and a back axle of an automobile, close to the tires, and the laser range finders are used for measuring the height distance from an instrument to ground; a height distance value is transmitted to the MCU control center and compared with a normal height distance range value; when the height distance value is lower than the normal height distance range value, the tires are inflated by the inflator through the inflation connecting device; when the height distance value reaches a normal height distance value, the inflator stops inflating, and the voice broadcast device is controlled by the MCU control center to broadcast that the tires are inflated by the inflator; a driver can judge the damaged condition of the tires in accordance with a broadcast frequency; and the selector switch is used for manually controlling whether the system is used or not. The automobile tire automatic inflation control system aims to inflate the tires only when an air pressure value of the tires of the automobile is not within a normal range, and the driver can judge the damaged condition of the tires through the system.
Description
Technical field
The utility model relates to a kind of control system, particularly a kind of motor tire automatic inflating control system.
Background technology
In the driving process of automobile, the whether normal safety that is directly connected to vehicle traveling process of motor tire state.Because people can't judge whether the motor tire state is normal in the process of driving, so people have invented a lot of automatic inflating device for tyre of vehicles, having gas filled device when tire pressure changes is that tire carries out automatic inflating.But these devices mostly are based on this principle of equilibrium of pressure of motor tire and make.Tire is in the situation that variation can occur to continue in impaired gas leakage air pressure, tire air pressure under different ambient pressures and different ambient temperature also can change but not have in short-term lasting variation, obviously the latter occurs in normal situation, so motor tire need not inflation in normal pressure range and when keeping constant, only have when air pressure of automobile tire just prove not in normal range and when constantly changing tire impaired need to for the interim inflation of tire to guarantee the automobile normal driving.But present motor tire dynamic gas pressure system can not judge the normal air pressure range of tire, and chaufeur also can't judged the tire damage situations on the run very soon.
Summary of the invention
The purpose of this utility model be only when the air pressure of automobile tire value is not in normal range dynamic gas pressure system just can be tyre inflating, and chaufeur can be judged the tire damage situations by this system.A kind of motor tire automatic inflating control system comprises laser rangefinder, MCU control center, inflation pump, select switch, voice announcer, inflating connector.Laser rangefinder is installed on the position of close tire on automobile front axle and the rear axle, be used for the height distance of measuring instrument to ground, the height distance value is transferred to MCU control center and compares with normal height distance value range, when being lower than normal height distance value range, inflation pump is tyre inflating by inflating connector, inflation pump stops inflation when reaching normal height distance value, it has been tyre inflating that MCU control center can make voice announcer report inflation pump, chaufeur can be according to the damage situations of reporting frequency and judge tire, select switch be used for this system of manual control use whether.
The utility model is the advantage of prior art relatively:
1. self-filler just can be tyre inflating when the air pressure of automobile tire value is not in normal range.
2. chaufeur can be judged the tire damage situations by the voice broadcast frequency.
Description of drawings
Fig. 1 is a kind of motor tire automatic inflating of the utility model control system structured flowchart
The specific embodiment
Use altogether 4 laser rangefinders in the utility model, be installed on respectively on automobile front axle and the rear axle position near tire, the instrument that laser rangefinder measures is to the height distance on a ground alternative value as the tire height.Normal height distance value range with motor tire in normally-pressured neighbor value (temperature, pressure, slightly the tire pressure that normal circumstances causes such as jolt changes) time is inputted MCU control center, when the height distance value that records was in normal height distance value range, MCU control center can not make inflation pump work.When the height distance value that records during less than normal height distance value range, MCU control center can make inflation pump start working, by inflating connector to tyre inflating.When the instrument that measures when laser rangefinder reached normalized distance from the altitude range value to the height distance on ground, inflation pump quit work, and MCU control center can make voice announcer report inflation pump to be tyre inflating.If tire flat is comparatively serious, then laser rangefinder meeting repeated detection is to the variation of height distance, MCU control center can repeatedly make inflation pump work, it has been tyre inflating that MCU control center can make voice announcer repeatedly report inflation pump, and chaufeur can be according to the damage situations of reporting frequency judgement tire.When automobile when smooth highway travels, chaufeur can be opened this system by select switch, when automobile when rugged mountain region road travels, chaufeur can be closed this system by select switch.
Claims (1)
1. motor tire automatic inflating control system, comprise laser rangefinder, MCU control center, inflation pump, select switch, voice announcer, inflating connector, it is characterized in that: described laser rangefinder is installed on the position of close tire on automobile front axle and the rear axle, be used for the height distance of measuring instrument to ground, the height distance value is transferred to MCU control center compares with normal height distance value range, and when being lower than normal height distance value range, inflation pump is tyre inflating by inflating connector, inflation pump stops inflation when reaching normal height distance value, MCU control center can make voice announcer report inflation pump to be tyre inflating, and chaufeur can be according to the damage situations of reporting frequency and judge tire, select switch be used for this system of manual control use whether.
