Description

Technical Field

[0001] This utility model relates to the field of motor technology, and specifically to an installation structure for a flat wire stator thermistor. Background Technology

[0002] With the development of new energy vehicles, the requirements for motors are becoming increasingly stringent. Most existing motors use flat-wire stators. To monitor and control the motor temperature and ensure it operates within a safe range, NTC (Negative Temperature Coefficient) thermistors are installed on the flat-wire stator. There are three main methods for installing these thermistors: First, the thermistor probe is pre-embedded between two layers of copper wire at the solder joint and fixed with a coating; the thermistor lead is then threaded through the winding and bound once. Second, the thermistor probe is pre-embedded between two layers of wire sheaths at the crown end and fixed with varnish; the thermistor lead is then threaded through the winding and bound once. Third, the thermistor probe is bound to the solder joint, fixed with heat-shrink tubing, and fixed with varnish; the thermistor lead is then threaded through the winding and bound once. Fixing with dripping paint may cause paint to stick to the oil tank or surface of the iron core, affecting the product's appearance; placing the thermistor in the middle of the soldering end may cause the thermistor probe to be installed incorrectly, which will result in inaccurate temperature measurement and failure to achieve the desired effect; all of the above installations require wire binding, and some products even require crimping plugs, all of which are manual operations with low installation efficiency. Summary of the Invention

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, one objective of this utility model is to provide a mounting structure for a flat wire stator thermistor, wherein the flat wire stator includes a stator core and a winding wound on the stator core, the thermistor includes a wire and a temperature sensing probe disposed at the end of the wire, and the mounting structure includes a busbar adapted to connect to the winding, the busbar being an elongated and arc-shaped structure, and having through holes and multiple grooves, wherein the through holes and the multiple grooves are arranged sequentially along the length direction of the busbar, the through holes allowing the temperature sensing probe of the thermistor to pass through, and the multiple grooves being adapted to accommodate the wire of the thermistor.

[0005] In addition, the mounting structure for flat wire stator thermistors according to this utility model may also have the following additional technical features.

[0006] Optionally, the busbar has a top surface and a bottom surface facing away from each other. A portion of the busbar near one end is provided with multiple legs extending downwards from the bottom surface. These legs are arranged around the through-hole to form a receiving cavity therebetween; the receiving cavity communicates with the through-hole. The multiple legs are used to insert into the winding for initial positioning of the busbar. Furthermore, the positions of the multiple legs in the winding correspond to the temperature detection positions of the thermistor's temperature sensing element. The thermistor's temperature sensing element is positioned between the multiple legs, i.e., within the receiving cavity, to quickly and accurately install the thermistor's temperature sensing element in the correct position in the winding, avoiding operational errors that could lead to incorrect detection data.

[0007] Optionally, the portion of the busbar near the through-hole is provided with multiple latching groups extending upward from the top surface. Each latching group includes two oppositely arranged latches, with a wire groove formed between the two oppositely arranged latches. This is to secure and guide the wires of the thermistor, preventing the thermistor wires from falling off.

[0008] Optionally, the plurality of latching groups includes a first latching group and a second latching group. The first latching group is disposed along the length of the busbar between the second latching group and the through hole and is close to the through hole. This is to secure and guide the thermistor's wires and prevent the thermistor's wires from falling off.

[0009] Optionally, the busbar is provided with a first groove, which is disposed adjacent to the second latching group. The second latching group is disposed between the first groove and the first latching group along the length direction of the busbar.

[0011] Optionally, the busbar further has a first sidewall and a second sidewall that at least partially define the second groove. The first sidewall and the second sidewall are disposed opposite to each other. The first sidewall has a plurality of first protrusions protruding toward the second sidewall, and the second sidewall has a plurality of second protrusions protruding toward the first sidewall. The first protrusions and the second protrusions are arc-shaped and are alternately arranged along the length of the busbar. The first protrusions and the second protrusions alternately engage and secure the leads of the thermistor to prevent them from falling off.

[0012] Optionally, the busbar is provided with a third latch and a boss, and a third groove is formed between the third latch and the boss; the busbar also has a third sidewall and a third latch that at least partially define the second groove, the third sidewall being disposed opposite to the third latch; the busbar also has a boss, the boss and the third latch being disposed adjacent to each other along the length direction of the busbar and forming a third groove between them. The lead of the thermistor is led out through the third groove for connection to a compatible terminal.

[0013] Optionally, the busbar is provided with a U-phase copper busbar, a V-phase copper busbar and a W-phase copper busbar arranged sequentially along its length.

[0014] Optionally, the busbar is further provided with a plurality of pins arranged sequentially along its length, the plurality of pins being adapted to be connected to the winding.

[0015] The installation structure of this application allows the temperature sensing part of the thermistor and the wire to be fixed on the busbar through multiple grooves, eliminating the need for binding and avoiding the possibility of damage to the wire during binding. The temperature sensing part of the thermistor is set in the winding through the through hole of the busbar, which can clearly define the installation position of the temperature sensing part and avoid incorrect installation. Therefore, the structure of this application can ensure the accuracy of the thermistor installation and improve the installation efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] An installation structure for a flat wire stator thermistor is disclosed. The flat wire stator includes a stator core 1 and a winding 2 wound on the stator core 1. The thermistor includes a wire and a temperature sensing probe disposed at the end of the wire. The installation structure includes a busbar 3, which is adapted to connect to the winding 2. The busbar 3 is an elongated and arc-shaped structure, and has through holes 31 and multiple grooves. The through holes 31 and multiple grooves are arranged sequentially along the length of the busbar 3. The through holes 31 allow the temperature sensing probe of the thermistor 7 to pass through, and the multiple grooves are adapted to accommodate the wire of the thermistor 7.

[0037] In some embodiments, the busbar 3 has a top surface 322 and a bottom surface 321 facing away from each other. A portion of the busbar 3 near one end is provided with a plurality of legs extending downward from the bottom surface 321. The plurality of legs are arranged around the through hole 31 to form a receiving cavity 33 therebetween. The receiving cavity 33 communicates with the through hole 31.

[0038] like Figure 1 and Figure 2 As shown, the thermistor mounting structure includes a busbar 3, which is an insulated, elongated, and arc-shaped structure. A through-hole 31 for the thermistor temperature sensor probe to pass through is provided near one end of the busbar 3. The busbar 3 also has a top surface 322 and a bottom surface 321 facing away from each other. A plurality of legs extending vertically downwards from the bottom surface 321 are provided near one end of the busbar 3. In this application, these include a first leg 331, a third leg 333 opposite to the first leg 331, and a second... The first leg 331, the second leg 332, the third leg 333, and the fourth leg 334 are arranged around the through hole 31 and form a receiving cavity 33 between them. The through hole 31 of the busbar 3 is connected to the receiving cavity 33. In actual use, multiple legs of the busbar 3 are inserted between the flat wires of the winding 2. The temperature sensing probe of the thermistor 7 is set in the receiving cavity 33 through the through hole 31 to facilitate the detection of the temperature of the winding 2.

[0039] In some embodiments, the portion of the busbar 3 near the through hole 31 is provided with a plurality of snap-fit ​​groups extending upward from the top surface 322, each snap-fit ​​group including two oppositely arranged snaps, with a wire groove formed between the two oppositely arranged snaps.

[0040] In some embodiments, the plurality of latching groups include a first latching group 34 and a second latching group 35. The first latching group 34 is disposed between the second latching group 35 and the through hole 31 and is close to the through hole 31 along the length direction of the busbar 3.

[0041] like Figure 3 and Figure 4 As shown, the portion of the busbar 3 near the through hole 31 is provided with multiple latching groups extending upward from the top surface 322. Each latching group includes two oppositely arranged latches, forming a wire groove between the two oppositely arranged latches. Specifically, in this example, a first latching group 34 and a second latching group 35 are provided. The first latching group 34 is disposed along the length direction of the busbar 3 between the second latching group 35 and the through hole 31 and is close to the through hole 31. The first latching group 34 includes a first left latch 341 and a first right latch 342, as shown... Figure 9As shown, the distance between the body of the first left latch 341 and the body of the first right latch 342 is d. The overall outer dimension of the thermistor 7 wire is smaller than d so that the wire can pass through and be accommodated in the wire slot. The upper part of the first left latch 341 extends towards the first right latch 342 to form an extension, and the upper part of the first right latch 342 extends towards the first left latch 341 to form an extension. The extensions of the first left latch 341 and the first right latch 342 are arranged opposite to each other. The extension of the first left latch 341 has a right end face 3411, and the extension of the first right latch 342 has a left end face 3421. The distance between the right end face 3411 and the left end face 3421 is c, where c < the overall outer diameter of the wire < d. Therefore, the thermistor 7 wire can be accommodated in the wire slot and confined within the wire slot by the action of the two extensions to prevent the wire from falling off. Similarly, the second latch group 35 includes a second left latch 351. The second right latch 352 and the second left latch 351 extend towards the second right latch 352 to form an extension portion, and the second right latch 352 extends towards the second left latch 351 to form an extension portion. The extension portions of the second left latch 351 and the second right latch 352 are arranged opposite to each other. The distance between the body of the second left latch 351 and the body of the second right latch 352 is d, and the distance between the extension portions of the second left latch 351 and the second right latch 352 is c, where c < the overall outer diameter of the wire < d. Therefore, the first latch group 34 and the second latch group 35 together form a wire groove to accommodate and guide the wire of the thermistor 7. At the same time, since each latch is provided with an extension portion, the wire of the thermistor 7 can be firmly clamped in the wire groove to prevent the wire from falling off. The corners of each extension portion are rounded to prevent the wire from being cut during installation or to prevent injury to the operator.

[0042] In some embodiments, the busbar 3 is provided with a first groove 36, the first groove 36 is disposed adjacent to a second latching group 35, the second latching group 35 is disposed between the first groove 36 and the first latching group 34 along the length direction of the busbar 3; the busbar 3 has a first bottom wall 361 that at least partially defines the first groove 36, the first bottom wall 361 gradually slopes upward along the direction away from the second latching group 35.

[0043] like Figure 3 and Figure 4 As shown, the busbar 3 is provided with a first groove 36, which is adjacent to the second latching group 35 and communicates with the wire groove. The second latching group 35 is disposed between the first groove 36 and the first latching group 34 along the length direction of the busbar 3. The busbar 3 has a first bottom wall 361 that at least partially defines the first groove 36. The first bottom wall 361 gradually slopes upward in a direction away from the second latching group 35 so as to gently guide the wire of the thermistor 7.

[0044] In some embodiments, the busbar 3 is further provided with a second groove 37, which is disposed adjacent to the first groove 36. The first groove 36 is disposed between the second groove 37 and the second snap-fit ​​assembly 35 along the length direction of the busbar 3. The busbar 3 has a second bottom wall 371 and a third bottom wall 372 that at least partially define the second groove 37. The second bottom wall 371 gradually slopes upward along a direction away from the first groove 36 until it connects with the third bottom wall 372, which is horizontally disposed.

[0045] In some embodiments, the busbar 3 further has a first sidewall 373 and a second sidewall 374 that at least partially define the second groove 37. The first sidewall 373 and the second sidewall 374 are disposed opposite to each other. The first sidewall 373 is provided with a plurality of first protrusions 3731 protruding toward the second sidewall 374, and the second sidewall 374 is provided with a plurality of second protrusions 3741 protruding toward the first sidewall 373. The first protrusions 3731 and the second protrusions 3741 are alternately disposed along the length direction of the busbar 3.

[0046] In some embodiments, the busbar 3 has a third sidewall 375 and a third latch 38 that at least partially define the second groove 37, the third sidewall 375 being disposed opposite to the third latch 38; the busbar 3 also has a boss 39, the boss 39 and the third latch 38 being disposed adjacent to each other along the length direction of the busbar 3 and forming a third groove 389 between them.

[0047] like Figure 5 and Figure 6As shown, the busbar 3 is also provided with a second groove 37, which is adjacent to the first groove 36. The first groove 36 is disposed between the second groove 37 and the second snap-fit ​​assembly 35 along the length direction of the busbar 3. The busbar 3 has a second bottom wall 371 and a third bottom wall 372 that at least partially define the second groove 37. The second bottom wall 371 gradually slopes upward along the direction away from the first groove 36, and the third bottom wall 372 is a horizontal surface. The second bottom wall 371 and the third bottom wall 372 are connected. The wire of the thermistor 7 is guided obliquely along the first groove 36 to the second groove 37, and then smoothly guided from the oblique surface of the second groove 37 to the horizontal section of the second groove 37 to realize the guidance of the wire of the thermistor 7. The busbar 3 also has a first sidewall 373 and a second sidewall 374 that at least partially define the second groove 37. The first sidewall 373 and the second sidewall 374 are disposed opposite to each other. The first sidewall 373 is provided with a plurality of first protrusions 3731 protruding toward the second sidewall 374, and the second sidewall 374 is provided with a plurality of second protrusions 3741 protruding toward the first sidewall 373. In this example, there are two first protrusions 3731 and two second protrusions 3741, and the first protrusions 3731 and the second protrusions 3741 are alternately disposed along the length of the busbar 3 to secure the wires of the thermistor 7 and prevent the wires from falling off. In addition, the first protrusions 3731 and the second protrusions 3741 have arc-shaped surfaces to prevent the wires from being scratched. Figure 6 As shown, the busbar 3 has a third sidewall 375 and a third latch 38 that at least partially define the second groove 37. The third sidewall 375 and the third latch 38 are disposed opposite to each other and are connected to the second sidewall 374 at an angle. The busbar 3 also has a boss 39. The boss 39 and the third latch 38 are disposed adjacent to each other along the length direction of the busbar 3 and form a third groove 389 between them. The portion of the third latch 38 near the upper end protrudes towards the third sidewall 375 to form an extension. In this example, the third latch 38 has the same structure as the first left latch 341 so as to snap and fix the wire of the thermistor 7. The wire of the thermistor 7 is led out from the third groove 389 so as to connect to the terminal.

[0048] In this application, as Figure 5 and Figure 8As shown, the width of the first groove 36 and the second groove 37 is b, and the distance between the first protrusion 3731 and the second sidewall 374 is a. Similarly, the distance between the second protrusion 3741 and the first sidewall 373 is a (not shown in the figure). Since the first protrusion 3731 and the second protrusion 3741 protrude into the groove respectively, a < b. The conductor of the thermistor 7 includes wires and a sheath surrounding the wires. In this example, the thermistor 7 includes two wires and a sheath that wraps around the two wires. The wire diameter is φ. The groove size of this application is b≈2φ+0.2. Therefore, when the sheath wraps around the two wires, the overall outer size of the conductor is approximately equal to or slightly larger than the groove size b, so as to ensure that the conductor of the thermistor 7 can be fully accommodated in the first groove 36 and the second groove 37. When the conductor of the thermistor 7 passes through the first protrusion 3731 and the second protrusion 3741, it can be firmly locked into the second groove 37 to prevent the conductor from falling off and to facilitate the installation of the thermistor 7 by the staff.

[0052] like Figure 5 and Figure 7 As shown, the busbar 3 is provided with a plurality of pins 30 arranged sequentially along its length. The plurality of pins 30 are respectively welded and fixed to the winding of the welding end of the winding 2 to achieve the fixation of the busbar 3.

[0053] The thermistor mounting structure for flat wire stators disclosed in this application allows the temperature-sensing part of the thermistor and the lead wire to be fixed on the busbar 3. Compared with the traditional method, the binding process is eliminated, avoiding the possibility of damage to the lead wire during the binding process.
