[0001] The application relates to the technical field of winding temperature measurement, and particularly relates to a motor winding temperature measurement mechanism. BACKGROUND

[0002] A driving motor is a core component of a new energy vehicle. Compared with a traditional round wire motor, a flat copper wire motor has high power and good heat dissipation. In a working process of the driving motor, the temperature rise of the motor is a key index, and the motor must be provided with a winding temperature rise acquisition device to provide accurate temperature rise results.

[0020] Further, the rotating assembly includes a rotor rotatably connected inside the main body, and an outer surface of the rotor is rotatably connected with the winding;

[0021] The temperature measuring assembly includes a signal transmission line fixedly connected to the side wall of the PLC controller, an end of the signal transmission line away from the PLC controller penetrates through the inner wall of the main body and extends to the inside, and an extension end of the signal transmission line is fixedly connected with a temperature measuring sensor.

[0022] Further, the limiting assembly includes a sliding rod slidably connected inside the sliding groove, and the U-shaped plate is made of elastic material;

[0023] The two U-shaped plates are fixedly connected with a fixed rod one, the outer surface of the fixed rod one is provided with two fixed rods two, and the two fixed rods two are fixedly connected between the two U-shaped plates.

[0034] The present application has the following advantages:

[0035] 1. The present application comprises a temperature measuring assembly, a sliding assembly and a stabilizing assembly. The rotation of the multiple flip plates pushes the coils to gather and press the side wall of the U-shaped plate, and the rotation of the flip plates also limits the position of the U-shaped plate by the contact between the hook plate of the side wall and the coils. When the motor works for a long time and generates vibration, the hollow plate slides to the side wall of the winding and is in an inclined state to block the side wall of the temperature sensor, forming a self-locking and anti-backup effect. This limits the sliding of the temperature sensor during vibration, ensuring the stability of the temperature sensor in position during motor operation and vibration, improving the stability of the temperature sensor in a vibrating environment, and enhancing the measurement accuracy and reliability during temperature measurement.

[0036] 2. The present application comprises a limiting assembly and a flip assembly. When the heat-conducting rod rotates and slides in the limiting ring, the bottom end of the limiting ring passes through the square hole in the flexible belt and contacts the inside of the densely packed coils. When the heat-conducting rod slides obliquely downward, it pushes the side wall of the elastic folding plate into contact with the outer surface of the temperature sensor. At this time, the heat-conducting property of the heat-conducting rod can transfer the temperature of the coils outside the temperature sensor to the side wall of the temperature sensor. The heat-conducting rod can also make the temperature measuring point of the temperature sensor penetrate into the inside of the densely packed winding coils, allowing it to directly measure a more uniform temperature distribution area. This reduces the over-concentration of coil density in the outer area of the temperature sensor caused by the flip plates pushing the coils to gather towards the U-shaped plate, and reduces the situation where the temperature of the coils inside the temperature sensor is higher than normal due to the high temperature caused by the pushing. This enhances the accuracy of temperature measurement, reduces measurement errors, and improves temperature measurement efficiency.

[0037] 3、The application, through the turnover assembly, when the flexible band is pushed into the inside of the coil by the heat conduction rod, the flexible band can form an isolation layer between the outer wall of the end of the heat conduction rod and the coil, at this time, the flexible band will gradually slide into the coil along with the sliding of the heat conduction rod, when the flexible band blocks between the heat conduction rod and the coil, it can reduce the damage to the surface coating of the coil caused by the friction between the coil and the heat conduction rod when the heat conduction rod is inserted into the coil, through the blocking of the flexible band, it can reduce the failure of the coil caused by the friction of the surface of the coil when the heat conduction rod slides, so as to ensure the stability of the device when measuring temperature.

[0038] 4、The application, through the auxiliary mechanism, when the elastic folding plate is unfolded, its side can increase the contact area between the U-shaped plate, through the unfolding of the elastic folding plate and the increase of the contact area between the two sides of the elastic folding plate and the U-shaped plate, a support body can be formed inside the U-shaped plate, through the support of the elastic folding plate in the U-shaped plate outside the temperature sensor, it can reduce the damage to the temperature sensor caused by the extrusion of the coil through the U-shaped plate when the coil is pushed to the direction of the U-shaped plate by the turnover plate, through the support of the elastic folding plate, it can further enhance the support strength of the U-shaped plate and improve the protection strength of the temperature sensor outside when measuring temperature.

[0039] Of course, implementing any product of the present application does not necessarily require achieving all the advantages described above at the same time. BRIEF DESCRIPTION OF DRAWINGS

[0082] In use, first, the signal transmission line 121 is connected with the PLC controller 101, then the main body 1 is opened, the temperature sensor 122 is inserted between the two U-shaped plates 201, then the U-shaped plates 201 are inserted into the winding coil at the end of the winding 112, then the main body 1 is assembled and closed, then the main body 1 is started, when the main body 1 drives the rotor 111 to rotate, the temperature generated by the rotor 111 is transmitted to the coil in the winding 112, at this time the temperature sensor 122 can detect the temperature inside the main body 1 and transmit the signal to the PLC controller 101 through the signal transmission line 121, at this time the PLC controller 101 receives the signal and judges whether it is over limit through the preset program, and controls the cooling system or cuts off the power supply, to achieve the purpose of detecting the temperature.

[0083] When the temperature sensor 122 is inserted between the two conical semicircular plates 221, the conical semicircular plates 221 will be pushed outward by the hollow plate 223 through the connecting plate 222 under the insertion of the temperature sensor 122, when the hollow plate 223 is turned outward, the rotation of the hollow plate 223 will directly insert into the coil of the winding 112, which will expand the contact area between the coil and the U-shaped plate 201, at the same time, when the hollow plate 223 rotates, the rotation of the hollow plate 223 will push the bottom of the Z-shaped plate 231 to make the Z-shaped plate 231 slide upward, when the Z-shaped plate 231 slides upward, the sliding of the Z-shaped plate 231 will push the right angle surface at the bottom of the C-shaped frame 232 to make the C-shaped frame 232 slide, when the C-shaped frame 232 slides, it will push the turnover plate 233 to rotate at the side wall of the U-shaped plate 201, at this time the rotation of the multiple turnover plates 233 will push the coil to gather and form a pre-tightening force on the side wall of the U-shaped plate 201, at the same time, the rotation of the turnover plate 233 will also contact the coil through the hook plate of the side wall to limit the position of the U-shaped plate 201, then when the motor works for a long time and generates vibration, when the temperature sensor 122 moves in position after being vibrated, the sliding of the temperature sensor 122 will drive the hollow plate 223 to slide, at this time the top end of the hollow plate 223 slides to the side wall of the winding 112 and forms a self-locking anti-backup effect in an inclined state at the side wall of the temperature sensor 122, so as to limit the sliding of the temperature sensor 122 when it is vibrated, thereby ensuring the stability of the temperature sensor 122 in position when the motor works and vibrates, and improving the stability of the temperature sensor 122 in the vibration environment, and enhancing the measurement accuracy and reliability in temperature measurement.

[0084] When the winding coils on both sides of the U-shaped plate 201 are pushed to extrude the U-shaped plate 201, because the U-shaped plate 201 is elastic, when the two sides of the U-shaped plate 201 are extruded by the pushed coils, the two sides of the U-shaped plate 201 will drive the right-angle blocks to relatively close, when the two sides of the U-shaped plate 201 close, the right-angle blocks will extrude the side wall of the heat conduction rod 313 downward, when the heat conduction rod 313 is extruded downward, it will slide in the limiting ring 312 while driving the limiting ring 312 to rotate, when the heat conduction rod 313 rotates and slides in the limiting ring 312, the bottom end of the limiting ring 312 will pass through the square hole on the flexible belt 311 and contact the inside of the pushed and relatively dense coils outside, at the same time, when the heat conduction rod 313 slides downward, it will push the side wall of the elastic folding plate 301 to contact the outer surface of the temperature measurement sensor 122, at this time, the heat conduction of the heat conduction rod 313 can transfer the coil temperature outside the temperature measurement sensor 122 to the side wall of the temperature measurement sensor 122, and then the temperature measurement point of the temperature measurement sensor 122 can be deepened into the inside of the dense winding coils through the heat conduction rod, so as to directly measure the area with more uniform temperature distribution, reduce the situation that the coil density of the area outside the temperature measurement sensor 122 is excessively concentrated when the turnover plate 233 pushes the coils to close to the direction of the U-shaped plate 201, and reduce the situation that the temperature of the coil inside is too high after being pushed, so that the heat of the temperature measurement point is higher than the normal temperature measurement, so as to enhance the accuracy during temperature measurement, reduce the measurement error, and improve the temperature measurement efficiency.

[0085] When the right-angle blocks extrude the side wall of the heat conduction rod 313 downward when the two U-shaped plates 201 relatively close, when the heat conduction rod 313 is extruded and slides, the sliding of the heat conduction rod 313 will push the side wall of the flexible belt 311, so that the side wall of the flexible belt 311 is pushed to enter the inside of the winding coils when it is attached to the surface of the heat conduction rod 313 and slides with the heat conduction rod 313, when the flexible belt 311 enters the inside of the coils under the pushing of the heat conduction rod 313, the flexible belt 311 can form an isolation layer between the outer wall of the end of the heat conduction rod 313 and the coils, at this time, the flexible belt 311 will gradually slide into the coils along with the sliding of the heat conduction rod 313, when the flexible belt 311 blocks between the heat conduction rod 313 and the coils, it can reduce the situation that the surface coating of the coils is damaged when the heat conduction rod 313 slides due to friction between the heat conduction rod 313 and the coils, so as to reduce the situation that the coils are damaged due to the friction of the surface of the coils when the heat conduction rod 313 slides, which affects the normal operation of the temperature measurement sensor 122, so as to ensure the stability of the device during temperature measurement.

[0086] When the flexible band 311 is pushed into the coil by the heat-conducting rod 313, the sliding of the flexible band 311 will pull the bottom of the elastic folding plate 301 to slide downward, when the bottom of the elastic folding plate 301 is pulled to slide downward, the elastic folding plate 301 can be unfolded at this time, when the elastic folding plate 301 is unfolded, the contact area between the side of the elastic folding plate 301 and the U-shaped plate 201 can be increased, through the unfolding of the elastic folding plate 301 and the increase of the contact area between the elastic folding plate 301 and the two sides of the U-shaped plate 201, a support can be formed inside the U-shaped plate 201, through the support of the elastic folding plate 301 inside the U-shaped plate 201 outside the temperature measuring sensor 122, the situation that the temperature measuring sensor 122 is squeezed and damaged when the coil is squeezed by the U-shaped plate 201 when the turnover plate 233 pushes the coil to move closer to the U-shaped plate 201 in the direction of the U-shaped plate 201 can be reduced, through the support of the elastic folding plate 301, the support strength of the U-shaped plate 201 can be further enhanced, and the protection strength of the temperature measuring sensor 122 outside when measuring temperature can be improved.
