Abstract
The utility model relates to a tire pressure monitoring system of an electric car. The tire pressure monitoring system of the electric car comprises an electric car controller and velocity measurement hall components which are arranged on wheels of the electric car. The tire pressure monitoring system of the electric car is characterized by further comprising a comparator which is connected with the electric car controller, the velocity measurement hall components consist of a front wheel velocity measurement hall component and a rear wheel velocity measurement hall component which are respectively arranged on a front wheel of the electric car and a rear wheel of the electric car, and the front wheel velocity measurement hall component and the rear wheel velocity measurement hall component are connected with the comparator. A tire pressure caution device is connected with the electric car controller. The tire pressure monitoring system of the electric car has the advantages of being simple in structure, low in cost, capable of preventing tires from leaking air, and accordingly improving security of the electric car.
Description
Technical field
The utility model belongs to technical field, particularly relates to a kind of tire pressure monitoring system of battery-driven car.
Background technology
Battery-driven car is the widely used vehicle during people live, and it compares the traditional pin treadmill, has quickly and easily advantage, and still, in the process of running at high speed, tire fault is that all drivers worry most, the most difficult prevention and produce the most serious problem of consequence.Especially the sweltering heat in summer is outdoor, and electric vehicle tyre scorches through the sun, and the internal temperature of tire is higher, and battery-driven car travels for a long time and makes the interior temperature of tire further raise in addition, easily causes and blows out, and easily causes accident.In addition, tire flat also is one of frequent fault that occurs of battery-driven car, usually under the state, slowly tire gas leakage is difficult to cause user's attention, when only having the direct roll extrusion of the wheel hub ground of wheel, the user can feel " vibrations ", just can perceive tire flat, but late, battery-driven car is difficult to continue to travel, and giving on the way, people bring very large inconvenience, remedy if perceive in advance tire flat and in time keep in repair, then can remove appreciiable trouble from, so, be necessary to add system or device that tire pressure is detected on the battery-driven car.On the market, rarely have the battery-driven car that possesses the tire pressure measuring ability, and few battery-driven car tire pressure checking system complex structure, cost is high, is not suitable for using on the cheap battery-driven car.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, cost is low, can prevent that thereby tire gas leakage from improving the tire pressure monitoring system of safety of electric vehicle.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of tire pressure monitoring system of battery-driven car, comprise controller for electric vehicle and be installed in the Hall element that tests the speed on the Electricmotor car wheel, it is characterized in that: also comprise the comparator that is connected with described controller for electric vehicle, the described Hall element that tests the speed comprises the front-wheel that is installed in respectively on front wheel of electric motorcar and rear wheels of electric vehicle Hall element and the trailing wheel Hall element that tests the speed that tests the speed, the described front-wheel Hall element Hall element that is connected with trailing wheel that tests the speed is connected with described comparator, is connected with the tire pressure alarming device on the described controller for electric vehicle.
The utility model can also adopt following technical scheme:
Described tire pressure alarming device be mounted on the instrument panel of electric vehicle telltale and or buzzer phone.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, namely design a kind of system for detecting tire pressure of battery-driven car, native system not only can effectively detect tire pressure, make troubles to the user because of tire fault preventing, improve the safety of battery-driven car, and the native system simplicity of design, easily realize, the fabrication and installation cost is low, is applicable to cheap Electrical Bicycle as the principal market competitive power.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of tire pressure monitoring system of battery-driven car.Comprise the Hall element that tests the speed, controller for electric vehicle, comparator.The Hall element that tests the speed comprises front-wheel Hall element and the trailing wheel Hall element that tests the speed that tests the speed, the front-wheel Hall element that tests the speed is installed on the front-wheel of battery-driven car, the trailing wheel Hall element that tests the speed is installed on the trailing wheel of battery-driven car, the front-wheel Hall element Hall element that is connected with trailing wheel that tests the speed is connected with comparator, comparator is connected with controller for electric vehicle, connect the tire pressure alarming device on the controller for electric vehicle, in the present embodiment, the tire pressure alarming device can be mounted in telltale or the buzzer phone on the instrument panel of electric vehicle, can have simultaneously telltale and buzzer phone on the instrument panel of electric vehicle.
The Hall element that tests the speed is mounted in the magnetic susceptibility spare of the wheel hub inside of wheel, on the battery-driven car, the wheel hub inside of wheel also is equipped with the magnet corresponding with the above-mentioned Hall element that tests the speed, during rotation of wheel, whenever magnet passes through the Hall element that tests the speed, the Hall element that tests the speed just sends an impulse singla, pitch time by two impulse singlas is finished speed monitoring, the Hall element that tests the speed is ubiquitous in the speed control system on the traditional electrical motor-car, simultaneously with its acquisition of signal final element as tire pressure monitoring system described in the utility model, can realize simplied system structure, reduce the effect of system cost.
Principle of work:
When the air pressure of front wheel of electric motorcar tire or rear tyre reduced, the weight of vehicle can make this theoretical running radius of tire of taking turns diminish, and causes its revolution ratio another one wheel fast.The Hall element that tests the speed sends the speed signal of two wheels to comparator, by after the comparator computing relatively to the controller for electric vehicle outgoing signal of battery-driven car, controller for electric vehicle control connected telltale and or buzzer phone work, to reach the purpose that monitors tire pressure.
Above-mentioned embodiment only is to functional descriptions of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model all drop within the protection domain of the present utility model.
