When sailing, by driving motor supplies power, when automobile is travelled in high velocity, power resources charge the battery simultaneously in engine.
The stator structure of motor is the form using piecemeal in hybrid vehicle, the stator structure for block form, it is necessary to
Coordinate by the way of centralized winding outlet, this mode directly limit the detection to stator winding temperature.
The temperature highest part of machine winding is that, in winding overhang, winding overhang radiating condition is poor；Currently for pure electronic
The distributed winding outlet form of motor, is that temperature sensor is directly embedded in into winding overhang, to realize to stator winding
Temperature detection, but this structure type is difficult to for centralized winding outlet method.
In the prior art, it is to use manual type by TEMP for the stator winding of centralized winding outlet method
Device is embedded in the slot for winding of machine winding, then is fixed with rope colligation, and the problem of it is present includes：One is the temperature in slot for winding
Degree be less than with winding overhang temperature, but this mode can not directly detect acquisition winding overhang temperature；Two be rope colligation
Form it cannot be guaranteed that, especially there is unstability in reliable contacts between sensor and tested surface in the case of vibrations；
Propose and passed out winding temperature in Application No. CN2013101038514 Patent Application Publication using heat transfer
Come, detected for the temperature passed out using thermocouple, but there is detection integrity problem in the detection temperature through heat transfer, and
There is error because of heat transmission belt.
The content of the invention
The present invention be for avoid present in above-mentioned prior art not enough there is provided a kind of survey of hybrid powder motor stator winding
Warm structure, realizes that the reliability for hybrid powder motor stator winding temperature is detected.
The present invention adopts the following technical scheme that to solve technical problem：
The characteristics of hybrid powder motor stator winding temperature measurement structure of the present invention is：
Temperature sensor is set, and the temperature sensor is to be pressed with survey using afterbody elastic component in the inner chamber of socket

Cap through hole is opened up on the cap of the hybrid powder motor, the socket of the temperature sensor is through cap through hole
It is inserted in electric machine casing, the socket is fixed on cap, and the temperature probe protruded out is utilized tail springs
Pretightning force contradict in the end of stator winding, realize the temperature detection to stator winding end.
The characteristics of hybrid powder motor stator winding temperature measurement structure of the present invention, lies also in：
Seal groove is set in the neck of the socket, the embedded sealing ring in the seal groove is existed using sealing ring
Sealing is formed between cap through hole and socket.
The elastic component is spring.
End cap is set in the afterbody of the socket, with the spring base of end cap formation tail springs.
It is to be threadedly coupled in the socket and end cap.
Compared with the prior art, the present invention has the beneficial effect that：
1st, the present invention is detected that testing result is accurate directly against winding overhang；
2nd, the present invention realizes the reliable contacts between temperature probe and tested surface using the pretightning force of afterbody elastic component,
Drastically increase the stability of detection process；
3rd, simple in construction, integrated level of the invention is high, be easily assembled.
