Description
Technical field
This utility model is related to a kind of electric bicycle spontaneous fire prevention protection device.
Background technology
Find according to relevant information investigation statisticses：Electric bicycle occur spontaneous combustion time great majority be respectively occurring at ride and
Charged state, accounting 54.3% and 37% respectively, minority is dead status.The reason riding condition occurs spontaneous combustion has electrical equipment, connects
The reasons such as fitting, electric wire and short circuit cause, and have that charger two ends plug is overheated, charger mistake during charging the reason there is spontaneous combustion
The reasons such as heat, over-charging of battery cause.But the spontaneous combustion extent of injury is high when charging, if because having an accident, often no when majority charges
Manual intervention is so that fault spread.From to a large amount of electric bicycle analyses that spontaneous combustion occurs, its cause and its process substantially may be used
It is divided into two classes, the first kind is the failure of insulation because electrical part and contact connector are overheated, causes short circuit to produce burning, second
Class is that mechanical-physical reason leads to electric wire breakage, Joint's falling off, aging circuit, humidity to cause overheat short circuit to burn.
In view of above-mentioned defect, the design people's actively in addition research and innovation, to founding a kind of electric bicycle spontaneous combustion
Prevention ＆ protection device is so as to more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model be provide one kind can and alarm and cut off the electricity supply fall
The electric bicycle spontaneous fire prevention protection device that low electric bicycle incidents of spontaneous combustion occurs.
Electric bicycle spontaneous fire prevention protection device of the present utility model, includes temperature inductor and DC relay, described
Temperature inductor includes microswitch, and described microswitch is to be connected by plain conductor with described DC relay, described micro-
It is provided with hot melt adhesive temperature inductor on dynamic switch, described microswitch is provided with sheet metal switch, described hot melt adhesive temperature
Inductor solidifies locking described sheet metal switch at normal temperatures, and described sheet metal switch is passed through with the thermal source part of electric bicycle
Thermal transfer junction connects.
Further, described thermal transfer junction is aluminium flake.
Further, described thermal transfer junction pincers briquetting is rolled in outside wire or tiling is bundled in surface at easy heating.
Further, described electric bicycle one or more temperature inductor of spontaneous fire prevention protection device, and to go here and there
Connection mode is connected in electric motor car current supply circuit and charge circuit.
Further, the switch normal-closed end of described microswitch is connected with light emitting diode.
By such scheme, this utility model at least has advantages below：1st, temperature sense body is PUR, without power supply
Power supply, therefore stable working state, reliability；2 circuit matching with induction apparatuss are simple, it is convenient to realize, cheap；3rd, feel
Reply as if temperature, therefore, good in anti-interference performance；4th, protection device can sense many places delivery in hot weather life point simultaneously, as long as sending out at one
Raw " fault thermal source " can be protected.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used for this utility model is described, but is not limited to scope of the present utility model.
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of electric bicycle spontaneous fire prevention described in this utility model one preferred embodiment is protected
Protection unit, includes temperature inductor and DC relay 5, and temperature inductor includes microswitch 1, microswitch 1 and direct current relay
Device 5 is to be connected by plain conductor, microswitch 1 is provided with hot melt adhesive temperature inductor 2, microswitch 1 is provided with gold
Belong to piece switch 3, hot melt adhesive temperature inductor 2 solidifies locking sheet metal switch 3, sheet metal switch 3 and electrical salf-walking at normal temperatures
The thermal source part of car is connected by thermal transfer junction 4.
Thermal transfer junction 4 is aluminium flake, and thermal transfer junction 4 pincers briquetting is rolled in outside wire or tiling is bundled in surface at easy heating.
Electric bicycle spontaneous fire prevention protection device is one or more temperature inductor, and is connected in a series arrangement
In electric motor car current supply circuit and charge circuit.
The normal-closed end 8 of microswitch 1 is connected with light emitting diode 6.
Operation principle of the present utility model is as follows：
It is arranged on electric bicycle with aluminium flake thermal transfer junction 4 to produce the place of thermal source and open with the sheet metal of microswitch 1
Close 3 connections, sheet metal switch 3 closure of microswitch 1 is dripped the hot melt adhesive temperature inductor 2 of fusing, waits PUR solid
After change, the position of sheet metal switch 3 is locked, and PUR solidifies the sheet metal switch 3 of locking microswitch 1 at normal temperatures, micro-
The common port 9 of dynamic switch 1 is closed with normally opened end 7, and line conduction, this state is always maintained at PUR melted by heat.
When the common port 9 of microswitch 1 is turned on normally opened end 7, the line bag 10 energising simultaneously adhesive of the DC relay 5 being attached thereto, make
The common port 9 obtaining DC relay 5 is connected with normally opened end 7, and connected load circuit is turned on current supply circuit, and load is normal
Work, as shown in Figure 1.After the sheet metal switch 3 of microswitch 1 is heated and reaches the softening temperature of PUR, PUR is opened
Begin to melt, when microswitch 1 internal resilience is more than the viscous force of the PUR after melting, sheet metal switch 3 flicks, and fine motion is opened
The common port 9 closing 1 separates disconnection, the line bag 10 power-off release of DC relay 5 with normally opened end 7, and its load switch disconnects, load
Power-off does not work, and reaches the purpose of prevention electric motor car " spontaneous combustion ".After the state of sheet metal switch 3 changes, open with fine motion
The light emitting diode 6 closing 1 normal-closed end 8 connection obtains electroluminescence, sends police instruction.
The above is only preferred implementation of the present utility model, be not limited to this utility model it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, can also do
Go out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
