Rotation of the multiple overturning plates can push the coil to be close to and gathered in the direction of the U-shaped plate, extrusion pre-tightening force is formed on the side wall of the U-shaped plate, meanwhile, rotation of the overturning plates can further limit the position of the U-shaped plate through contact of hook plates on the side wall and the coil, and then when the motor works for a long time and vibrates, the U-shaped plate is prevented from being damaged. At the moment, when the hollow plate slides, the top end of the hollow plate slides to the side wall of the winding and is blocked at the side wall of the temperature measurement sensor in an inclined state to form a self-locking and anti-retreating effect, so that sliding of the temperature measurement sensor during vibration is limited, and the temperature measurement sensor can be ensured to be stable in position when the motor works and vibrates; therefore, the stability of the temperature measurement sensor in a vibration environment can be improved, and the measurement precision and reliability during temperature measurement are enhanced.

Description

Technical Field

[0001] The present invention relates to the technical field of winding temperature measurement, in particular to a motor winding temperature measurement mechanism. Background Art

[0002] The drive motor is a core component of new energy vehicles. Compared to traditional round wire motors, flat copper wire motors offer higher power and better heat dissipation. During operation, the temperature rise of the drive motor is a key indicator. Therefore, the motor must be equipped with a winding temperature rise acquisition device to provide accurate temperature rise results.

[0003] When the motor unit is in use, the motor winding needs to be measured for temperature. Generally, the temperature is measured by inserting a thermistor into the coil in the winding. Since the motor will vibrate when it is working, when the motor works for a long time, the vibration generated by the motor will be transmitted to the sensor in the winding, causing the sensor to move in the winding, affecting the stability of the temperature measurement point of the sensor in the winding, and also affecting the measurement accuracy and reliability during temperature measurement.

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

[0023] Among them, a fixing rod 1 is fixedly connected between the two U-shaped plates, and two fixing rods 2 are provided on the outer surface of the fixing rod 1. The two fixing rods 2 are fixedly connected between the two U-shaped plates.

[0024] Furthermore, the top and bottom of the U-shaped plate are fixedly connected with right-angle blocks;

[0025] The sliding assembly includes a conical semicircular plate slidably connected between two sliding rods, and the side wall of the conical semicircular plate is rotatably connected to a connecting plate;

[0032] Furthermore, the flip assembly includes a flexible belt fixedly connected to the bottom of the elastic folding plate, and a square hole is opened on the side wall of the flexible belt;

[0033] One end of the flexible belt away from the elastic folding plate is fixedly connected to a limiting ring and is rotatably connected to the inside of the U-shaped plate. The inside of the limiting ring is slidably connected to a heat-conducting rod. The outer surface of the heat-conducting rod is fixedly connected to two short rods, which are in contact with the side wall of the flexible belt.

[0034] The present invention has the following beneficial effects:

[0035] 1. In the present invention, through the temperature measuring component, the sliding component and the stabilizing component, the rotation of the multiple flip plates will push the coils to move closer to the U-shaped plate and form a squeezing pre-tightening force on the side walls of the U-shaped plate. At the same time, the rotation of the flip plates will contact the coils through the hook plates on the side walls to limit the position of the U-shaped plate. Later, when the motor works for a long time and generates vibrations, the top end of 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 to form a self-locking and anti-retraction effect, thereby limiting the sliding of the temperature sensor during vibration, and thus ensuring the stability of the temperature sensor in position when the motor is working and vibrating, thereby improving the stability of the temperature sensor in a vibration environment and enhancing the measurement accuracy and reliability during temperature measurement.

[0036] 2. The present invention, through the limiting component and the flipping component, when the heat-conducting rod rotates and slides in the limiting ring, the bottom end of the limiting ring will pass through the square hole on the flexible belt and contact the inside of the external coil which is denser after being pushed. At the same time, when the heat-conducting rod slides obliquely downward, it will push the side wall of the elastic folding plate to contact the outer surface of the temperature sensor. At this time, the thermal conductivity of the heat-conducting rod can transfer the coil temperature outside the temperature sensor to the side wall of the temperature sensor, and then the temperature measuring point of the temperature sensor can be penetrated into the dense winding coil through the heat-conducting rod, so that it can directly measure the area with more uniform temperature distribution, reduce the situation where the coil density in the external area of the temperature sensor is excessively concentrated when the flipping plate pushes the coil toward the direction of the U-shaped plate, resulting in local high density and heat accumulation, and reduce the situation where the heat of the temperature measuring point is higher than the normal temperature measurement due to the excessive temperature inside the coil after being pushed, thereby enhancing the accuracy of temperature measurement, reducing measurement errors, and improving temperature measurement efficiency.

[0037] 3. The present invention, through the flipping assembly, when the flexible belt enters the interior of the coil under the push of the heat-conducting rod, the flexible belt can form an isolation layer between the outer wall of the end of the heat-conducting rod and the coil. At this time, the flexible belt will gradually slide into the coil as the heat-conducting rod slides. When the flexible belt blocks between the heat-conducting rod and the coil, it can reduce the situation where the heat-conducting rod damages the surface coating of the coil when sliding due to the friction between the heat-conducting rod and the coil when inserted into the coil. The blocking of the flexible belt can reduce the situation where the coil fails due to the friction between the coil surface and the heat-conducting rod when sliding, which affects the normal operation of the temperature measuring sensor, thereby ensuring the stability of this device during temperature measurement.

[0038] 4. The present invention, through the auxiliary mechanism, when the elastic folding plate is unfolded, its side surface can increase the contact area with the U-shaped plate. By unfolding the elastic folding plate and increasing the contact area between the elastic folding plate and the two sides of the U-shaped plate, a support body can be formed inside the U-shaped plate. When the elastic folding plate is supported inside the U-shaped plate outside the temperature sensor, the situation in which the coil squeezes the temperature sensor through the U-shaped plate when the flip plate pushes the coil toward the U-shaped plate, causing the temperature sensor to be squeezed and damaged, can be reduced. The support of the elastic folding plate can further enhance the supporting strength of the U-shaped plate and improve the external protection strength of the temperature sensor during temperature measurement.

[0039] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The flip assembly 31 is installed on the side wall of the elastic folding plate 301 .

[0068] The rotating assembly 11 includes a rotor 111 rotatably connected to the interior of the main body 1 , and a winding 112 is rotatably connected to the outer surface of the rotor 111 ;

[0069] The temperature measuring component 12 includes a signal transmission line 121 fixedly connected to the side wall of the PLC controller 101. The end of the signal transmission line 121 away from the PLC controller 101 passes through the inner wall of the main body 1 and extends to the interior. The extended end of the signal transmission line 121 is fixedly connected to a temperature sensor 122. The signal transmission line 121 is first connected to the PLC controller 101. Then, after opening the main body 1, the temperature sensor 122 is first inserted between the conical semicircular plates 221 in the two U-shaped plates 201, and then the U-shaped plate 201 together with the temperature sensor 122 is inserted into the winding coil at the end of the winding 112.

[0070] The limiting assembly 21 includes a sliding rod 211 slidably connected to the interior of the sliding groove 202 , and the U-shaped plate 201 is made of elastic material;

[0071] Among them, a fixing rod 1 212 is fixedly connected between the two U-shaped plates 201 , and two fixing rods 213 are provided on the outer surface of the fixing rod 1 212 . The two fixing rods 213 are fixedly connected between the two U-shaped plates 201 .

[0072] The top and bottom of the U-shaped plate 201 are fixedly connected with right-angle blocks;

[0073] The sliding assembly 22 includes a conical semicircular plate 221 slidably connected between the two sliding rods 211 , and a connecting plate 222 is rotatably connected to the side wall of the conical semicircular plate 221 ;

[0074] The end of the connecting plate 222 away from the conical semicircular plate 221 is rotatably connected to the hollow plate 223, and the hollow plate 223 is slidably connected to the outer surface of the fixing rod 212;

[0075] A return spring is fixedly connected to the interior of the hollow plate 223 . When the hollow plate 223 rotates outward, the rotation of the hollow plate 223 will directly insert into the coil of the winding 112 .

[0076] The sliding member includes a Z-shaped plate 231 slidably connected to the outer surface of the two fixing rods 213, and a C-shaped frame 232 is provided on the side of the Z-shaped plate 231 away from the hollow plate 223;

[0077] Among them, the bottom of the C-shaped frame 232 is set at a right angle, and the C-shaped frame 232 is slidably connected between the two U-shaped plates 201. The rotation of the hollow plate 223 will push the bottom of the Z-shaped plate 231 so that the Z-shaped plate 231 slides upward. When the Z-shaped plate 231 slides upward, the sliding of the Z-shaped plate 231 will push the right-angled surface at the bottom of the C-shaped frame 232 to push the C-shaped frame 232 to slide.

[0078] The stabilizing assembly 23 includes two flip plates 233 rotatably connected to the inside of the C-shaped frame 232 , and the side walls of the flip plates 233 are fixedly connected with hook plates;

[0079] The two flip plates 233 are slidably connected to the side wall of the U-shaped plate 201 at one side close to the U-shaped plate 201 .

[0080] The flip assembly 31 includes a flexible belt 311 fixedly connected to the bottom of the elastic folding plate 301, and a square hole is opened on the side wall of the flexible belt 311;

[0081] The end of the flexible belt 311 away from the elastic folding plate 301 is fixedly connected to the limiting ring 312, and is rotatably connected to the inside of the U-shaped plate 201. The inside of the limiting ring 312 is slidably connected to the heat-conducting rod 313, and the outer surface of the heat-conducting rod 313 is fixedly connected to two short rods, which contact the side walls of the flexible belt 311. When the heat-conducting rod 313 is squeezed obliquely downward, it will slide in the limiting ring 312 and drive the limiting ring 312 to rotate. When the heat-conducting 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 external coil which is more dense after being pushed.

[0082] During use, first connect the signal transmission line 121 to the PLC controller 101, then open the main body 1 and insert the temperature sensor 122 between the conical semicircular plates 221 in the two U-shaped plates 201, then insert the U-shaped plate 201 together with the temperature sensor 122 into the winding coil at the end of the winding 112, then assemble and close the main body 1, and then start the main body 1. When the main body 1 drives the rotor 111 to rotate, the temperature generated will be 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, after receiving the signal, the PLC controller 101 determines whether it exceeds the 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 measuring sensor 122 is inserted between the two conical semicircular plates 221, the conical semicircular plate 221 will push the hollow plate 223 to rotate outward through the connecting plate 222 under the insertion of the temperature measuring sensor 122. When the hollow plate 223 rotates outward, the rotation of the hollow plate 223 will directly insert into the coil of the winding 112, thereby expanding 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 so that the Z-shaped plate 231 slides upward. When the Z-shaped plate 231 slides upward, the sliding of the Z-shaped plate 231 will push the right-angled surface at the bottom of the C-shaped frame 232 to push the C-shaped frame 232 to slide. When the C-shaped frame 232 slides, it will push the flip plate 233 to rotate at the side wall of the U-shaped plate 201. At this time, the rotation of multiple flip plates 233 will push the coil toward the direction of the U-shaped plate 201. The two plates 230 and 231 are respectively arranged to be parallel to each other, and the two plates 231 are respectively arranged to be parallel to each other, and the two plates 232 are respectively arranged to be parallel to each other, and the two plates 233 are respectively arranged to be parallel to each other, and the two plates 234 are respectively arranged to be parallel to each other, and the two plates 235 are respectively arranged to be parallel to each other, and the two plates 236 are respectively arranged to be parallel to each other, and the two plates 237 are respectively arranged to be parallel to each other, and the two plates 238 are respectively arranged to be parallel to each other, and the two plates 239 are respectively arranged to be parallel to each other, and the two plates 240 are respectively arranged to be parallel to each other, and the two plates 241 are respectively arranged to be parallel to each other, and the two plates 242 are respectively arranged to be parallel to each other, and the two plates 243 are respectively arranged to be parallel to each other, and the two plates 243 are respectively arranged to be parallel to each other, and the two plates 244 are respectively arranged to be parallel to each other, and the two plates 245 are respectively arranged to be parallel to each other, and the two plates 246 are respectively arranged to be parallel to each other, and the two plates 247 are respectively arranged to be parallel to each other, and the two plates 248 are respectively arranged to be parallel to each other, and the two plates 249 are respectively arranged to be parallel to each other, and the two plates 250 are respectively arranged to be parallel to each other, and the two plates 251 are respectively arranged to be parallel to each other, and the two plates 252 are respectively arranged to be parallel to each other, and the two plates 253 are respectively arranged to be parallel to each other, and the two plates 254 are respectively arranged to be parallel to each other, and the two plates 255 are respectively arranged to be parallel to each other, and the two plates 256 are respectively arranged to be parallel to each other, and the two

[0084] When the winding coils on both sides of the U-shaped plate 201 are pushed and squeeze the U-shaped plate 201, due to the elasticity of the U-shaped plate 201, when the two sides of the U-shaped plate 201 are squeezed by the coils being pushed, the two sides of the U-shaped plate 201 will drive the right-angle blocks to move closer together. When the two sides of the U-shaped plate 201 move closer together, the side walls of the heat-conducting rod 313 will be squeezed obliquely downward through the right-angle blocks. When the heat-conducting rod 313 is squeezed obliquely downward, it will slide in the limiting ring 312 and drive the limiting ring 312 to rotate. When the heat-conducting 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 coil that is denser after being pushed. At the same time, when the heat-conducting rod 313 is squeezed obliquely, When sliding down, the side wall of the elastic folding plate 301 will be pushed to contact the outer surface of the temperature sensor 122. At this time, the thermal conductivity of the heat-conducting rod 313 can transfer the coil temperature outside the temperature sensor 122 to the side wall of the temperature sensor 122, and then the temperature measuring point of the temperature sensor 122 can be penetrated into the dense winding coil through the heat-conducting rod, so that it can directly measure the area with more uniform temperature distribution, reduce the excessive concentration of coil density in the external area of the temperature sensor 122 when the flip plate 233 pushes the coil toward the direction of the U-shaped plate 201, resulting in high local density and heat accumulation, and reduce the situation where the heat of the temperature measuring point is higher than the normal temperature measurement due to the excessive temperature inside the coil after being pushed, thereby enhancing the accuracy of temperature measurement, reducing measurement errors, and improving temperature measurement efficiency.

[0085] When the right-angle block squeezes the side wall of the heat-conducting rod 313 obliquely downward when the two U-shaped plates 201 are relatively close to each other, when the heat-conducting rod 313 slides after being squeezed, the sliding of the heat-conducting rod 313 pushes the side wall of the flexible belt 311, so that the side wall of the flexible belt 311 is pressed and adheres to the surface of the heat-conducting rod 313 and enters the interior of the winding coil along with the heat-conducting rod 313 when the heat-conducting rod 313 slides. When the flexible belt 311 enters the interior of the coil under the push of the heat-conducting rod 313, the flexible belt 311 can form a gap between the outer wall of the end of the heat-conducting rod 313 and the coil. The flexible belt 311 will gradually slide into the coil as the heat-conducting rod 313 slides. When the flexible belt 311 blocks the heat-conducting rod 313 and the coil, it can reduce the friction between the heat-conducting rod 313 and the coil when the heat-conducting rod 313 is inserted into the coil, causing the heat-conducting rod 313 to damage the surface coating of the coil when sliding. The blocking of the flexible belt 311 can reduce the friction between the coil surface and the heat-conducting rod 313 when sliding, causing the coil to malfunction and affect the normal operation of the temperature measurement sensor 122, thereby ensuring the stability of the device during temperature measurement.

[0086] When the flexible belt 311 enters the coil under the push of the heat conducting rod 313, the sliding of the flexible belt 311 will pull the bottom of the elastic folding plate 301 to slide downward. When the bottom of the elastic folding plate 301 slides downward after being pulled, the elastic folding plate 301 can be unfolded. When the elastic folding plate 301 is unfolded, its side surface can increase the contact area with the U-shaped plate 201. By unfolding the elastic folding plate 301 and increasing the contact area between the elastic folding plate 301 and the two sides of the U-shaped plate 201, the U-shaped plate 201 can be unfolded. A support body is formed inside the U-shaped plate 201. When the elastic folding plate 301 supports the U-shaped plate 201 outside the temperature sensor 122, it can reduce the situation where the coil squeezes the temperature sensor 122 through the U-shaped plate 201 when the flip plate 233 pushes the coil toward the U-shaped plate 201, causing the temperature sensor 122 to be squeezed and damaged. The support of the elastic folding plate 301 can further enhance the supporting strength of the U-shaped plate 201 and improve the external protection strength of the temperature sensor 122 during temperature measurement.
