Abstract
The utility model discloses an engine temperature automatic alarm device, which is characterized by comprising a temperature sensor, a temperature display and an alarm device which are connected through an electronic control unit, wherein the temperature sensor is arranged on an engine; a normal working temperature range for the engine is previously set according to the working condition characteristic of a motorcycle; and the set normal working temperature range for the engine is input into the electronic control unit. In the utility model, the engine temperature automatic alarm device is arranged on the motorcycle, so that failure deadly caused by over-high temperature of the engine can be avoided, the engine can be effectively protected, damage to a motorcycle body and abnormal wear of a moving part can be avoided, and the service life of the engine is greatly prolonged.
Description
Technical field
The utility model relates to a kind of autoalarm, relates in particular to a kind of motorcycle engine temperature autoalarm.
Background technique
Motorcycle engine is the device that typically chemical energy of fuel is converted into mechanical energy; It is through detonation; High temperature, the pressurized gas that compressed fuel gas burning is produced promote the descent of piston with the crank mechanism interlock, thereby produce mechanical energy, and outputting power.Because the heat of high temperature and high pressure gas mainly dispels the heat through modes such as conduction, radiation, need to form heat absorption, exothermic equilibrium, could guarantee the motor proper functioning, when engine temperature is too high, can produces damage and the motion component are produced inordinate wear body.
Existing motorcycle engine does not all possess automatic warning function; When motor was in accurate failure phase owing to temperature is too high, the user can't know, and continued operation; Thereby miss the chance that motor is checked, keeped in repair; Usually can cause motor critical failure to occur, like bent axle, piston locking, engine scuffing, transmission system damage etc.
The model utility content
The purpose of the utility model is to provide a kind of can judge whether engine operating temperature normally also sends the engine temperature autoalarm of alarm signal automatically.
The purpose of the utility model is to realize like this; A kind of engine temperature autoalarm; It is characterized in that: comprise that temperature transducer, temperature show and warning device also connects through electronic control unit; Said temperature transducer is arranged on the motor, preestablishes motor normal working temperature scope according to motorcycle operating mode characteristics, input motor normal working temperature scope setting value in the said electronic control unit; Said temperature demonstration and warning device can send alarm signal automatically when engine operating temperature exceeds said setting value, thereby reach the warning purpose.
Said temperature shows and warning device is the temperature display lamp.
The said temperature sensor comprises that establishing temperature-sensitive chip, plug-in unit, heat conduction potting compound and envelope also installs in the enclosure.
For the ease of checking, said temperature shows and warning device is installed on the instrument panel.
The utility model utilizes engine temperature sensing unit temperature resistance characteristic; When engine temperature signal imports above-mentioned electronic control unit into; Electronic control unit can judge automatically whether this temperature is within the range of set temperature; When the temperature departure setting value, electronic control unit can send alarm signal by the indicated temperature display lamp.When the user finds that the temperature display lamp is reported to the police, can check, safeguard vehicle, avoid causing the motor critical failure, thereby reach the purpose of effective protection motor owing to engine temperature is too high.
The utlity model has following beneficial effect; The utility model is provided with the engine temperature autoalarm on motorcycle; Can avoid occurring critical failure owing to engine temperature is too high; Effectively protect motor, and avoided body injury and the inordinate wear of motion component, increased substantially the working life of motor.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 is the utility model example structure schematic representation;
Fig. 2 is the utility model embodiment arrangement of temperature sensor schematic representation.
Fig. 3 is the utility model embodiment temperature sensor circuit figure.
Embodiment
Embodiment; A kind of engine temperature autoalarm; Referring to Fig. 1; Comprise that temperature transducer 6, temperature show and warning device 7, temperature transducer 6 is arranged on the motorcycle engine 9 and with temperature demonstration and warning device 7 and is connected through electronic control unit 8, and temperature shows and warning device 7 is installed on the instrument panel; Referring to Fig. 2, temperature transducer 6 comprises to be established temperature-sensitive chip 4, plug-in unit 3, heat conduction potting compound 5 and envelope 2 and is installed in the shell 1; Temperature shows and warning device 7 is the temperature display lamp.According to the pre-set motor normal working temperature of motorcycle operating mode characteristics scope, and with in the motor normal working temperature scope setting value input electronic control unit 8.
Referring to Fig. 3 temperature sensor circuit figure, slot THA is the external temperature sensor interface, and AN1 meets microprocessor AD and gathers pin, and C1 is a filter capacitor, and R1 is the divider resistance of 10K; R4 and C6 constitute the RC eliminator jointly, prevent that external interference from being scurried like microprocessor internal by the AN1 pin, increase electronic control unit 8 antijamming capabilities.When the information of voltage that is input to electronic control unit 8 by AN1 end is a temperature information not in calibration range the time, electronic control unit 8 is that the decidable engine temperature is unusual, and indicated temperature shows and warning device 7 sends alarm signal.
Claims (4)
1. engine temperature autoalarm; It is characterized in that: comprise that temperature transducer (6), temperature show and warning device (7) also connects through electronic control unit (8); Said temperature transducer (6) is arranged on the motor (9); Input motor normal working temperature scope setting value in the said electronic control unit (8), when motor (9) when operating temperature exceeds said setting value said temperature show and warning device (7) can send alarm signal automatically.
2. engine temperature autoalarm as claimed in claim 1 is characterized in that: said temperature shows and warning device (7) is the temperature display lamp.
3. according to claim 1 or claim 2 engine temperature autoalarm, it is characterized in that: said temperature transducer (6) comprises temperature-sensitive chip (4), plug-in unit (3), heat conduction potting compound (5) and envelope (2) and is installed in the shell (1).
