Description

Technical Field

[0001] This utility model relates to the field of motor core technology, specifically to an automotive drive motor core. Background Technology

[0002] The core of an automotive drive motor is a key component in electric vehicles used to support and fix the motor coils. It is usually made of high-performance silicon steel sheets with special magnetic permeability and permeability to optimize the efficiency and performance of the motor. Its main function is to provide a stable magnetic circuit so that electrical energy can be effectively converted into mechanical energy. When current passes through the motor coils, the generated magnetic field produces magnetic flux in the core.

[0003] Patent No. 202322356702.0 discloses an iron core for an automotive drive motor. This device can move the second winding plate by rotating the adjusting screw to adjust the length, making it convenient to wind different amounts of copper wire according to requirements.

[0004] However, in the existing automotive drive motor core, the position of the second winding plate is adjusted by adjusting screws and threaded grooves. However, when adjusting the second winding plate, it is necessary to turn the adjusting screws on each group of second winding plates in turn. The operation steps are cumbersome and the workload is large. At the same time, the position of each group of second winding plates cannot be accurately controlled, which has a certain impact on the adjustment efficiency of the second winding plate and the efficiency of copper wire winding. Therefore, an automotive drive motor core is designed. Utility Model Content

[0005] The main purpose of this utility model is to provide an automotive drive motor core. This utility model solves the problems of inconvenience in adjusting the position of the winding plate B and low winding efficiency of copper wire in existing automotive drive motor cores by setting up a ring sleeve A, a ring sleeve B, a support plate A, a support plate B, a fixing rod, a spring, a fixing hole, and a connecting block.

[0006] The technical solution adopted by this utility model to solve its technical problem is an automotive drive motor core, including a motor core body. A winding plate A is symmetrically welded to the outside of the motor core body, and a winding plate B is slidably connected to the inside of winding plate A. An arc plate for winding copper wire is welded to the outside of winding plate B. A spring is welded inside winding plate A, and a fixing rod for fixing winding plate B is inserted into the inside of the spring. Several fixing holes are provided on the surface of winding plate B to allow the fixing rod to enter the interior of winding plate B. A rubber sleeve tightly connected to the fixing hole is adhered to the outside of the fixing rod. A connecting block for moving the fixing rod is welded to one side of the fixing rod. A ring A is inserted into the top of winding plate A, and a support plate A is welded to one side of ring A. A groove for relieving pressure on the connecting block is provided on the surface of support plate A. A ring B is inserted into the bottom of winding plate A, and a support plate B is welded to one side of ring B. Scale lines for precise adjustment of the position of winding plate B are symmetrically arranged on the surface of winding plate B.

[0007] By adopting the above technical solution, when adjusting the winding plate B, ring A and ring B are pulled outwards respectively. Then, ring A moves support plate A, and ring B moves support plate B. The groove on support plate A moves to the outside of the connecting block installed on the winding plate A. Subsequently, the spring inside the winding plate A causes the connecting block to pop outwards, allowing it to enter the groove. Then, the fixing rod on one side of the connecting block moves out of the fixing hole on the winding plate B. Since there are two sets of springs, fixing rods, and connecting blocks inside the winding plate A, the winding plate B is released from its fixed position. Then, the winding plate B is pulled outwards, and it moves out of the winding plate A. Observe the scale lines on the winding plate B to determine the position of the limit plate B. Then, press the ring A and ring B to move. Ring A moves the support plate A, and ring B moves the support plate B. Then, the support plate A presses the connecting block on the winding plate A. The outer sides of the connecting block are tilted towards the center, so that the support plate A presses the connecting block into the winding plate A. Then, the spring inside the winding plate A is compressed. Then, the connecting block moves the fixing rod into another fixing hole opened on the winding plate B. The rubber sleeve outside the fixing rod is in close contact with the inside of the fixing hole, so that the winding plate B is fixed, which makes it easier to adjust the position of the winding plate B and improve the winding efficiency of copper wire.

[0008] Specifically, the surface of the winding plate A is symmetrically provided with connecting grooves that limit the positioning of the ring A and the ring B. A magnetic block B connected to the ring A is fixed to the inside of the connecting groove with screws. A magnetic block A is fixed to the outside of both the support plate A and the support plate B with screws.

[0009] By adopting the above technical solution, after the winding plate B is adjusted, the ring A drives the support plate A to move, and the ring B drives the support plate B to move. Then, the ring A and the ring B respectively enter the symmetrically opened connecting slots on the winding plate A. Then, the magnetic block B in the connecting slot magnetically attracts the ring A and the ring B. Then, the support plate A on the ring A is stuck outside the winding plate A, and the support plate B outside the ring B is stuck outside the winding plate A. Then, the magnetic block A installed on the support plate A and the support plate B are magnetically connected, thereby improving the stability of the connection between the ring A and the ring B and the winding plate A respectively.

[0010] Specifically, the surface of the winding plate A is symmetrically provided with limiting grooves, and a limiting block connected to the winding plate B is slidably connected to the inner side of the limiting groove.

[0011] By adopting the above technical solution, when the winding plate B moves inside the winding plate A, the limiting blocks symmetrically welded to the outside of the winding plate B slide in the limiting grooves symmetrically opened on the winding plate A, thereby improving the stability of the movement of the limiting plate B.

[0012] Specifically, the surface of the winding plate A is symmetrically welded with fixing blocks that limit the positioning of the support plate A and the support plate B.

[0013] By adopting the above technical solution, when support plate A and support plate B move, the fixing blocks symmetrically installed on the winding plate A limit support plate A and support plate B, preventing support plate A and support plate B from falling off the winding plate A.

[0014] Specifically, the arc plate is symmetrically welded with support blocks to prevent the copper wires from shifting.

[0015] By adopting the above technical solution, when the copper wire is wound around the outside of the arc plate, the support block outside the arc plate limits the copper wire and prevents the copper wire from deviating.

[0016] The beneficial effects of this utility model are:

[0017] (1) In the automobile drive motor core described in this utility model, when the winding plate B needs to be adjusted, the ring A and ring B are pulled outwards respectively. Then, ring A drives the support plate A to move, and ring B drives the support plate B to move. Then, the groove on the support plate A moves to the outside of the connecting block installed on the winding plate A. Subsequently, the spring in the winding plate A drives the connecting block to pop outwards, so that the connecting block enters the groove. Then, the fixing rod on one side of the connecting block moves out of the fixing hole on the winding plate B. The spring, fixing rod and connecting block in the winding plate A are all provided in two sets, so that the winding plate B is released from the fixation. Then, the winding plate B is pulled outwards, and the winding plate B is released from the winding plate. Move plate A out and observe the scale lines on winding plate B to determine the position of limit plate B. Then, press ring A and ring B to move. Ring A drives support plate A to move, and ring B drives support plate B to move. Then, support plate A presses the connecting block on winding plate A. The outer sides of the connecting block are all tilted inward, so that support plate A presses the connecting block into winding plate A. Then, the spring inside winding plate A is compressed. Then, the connecting block drives the fixing rod into another fixing hole opened on winding plate B. The rubber sleeve outside the fixing rod is in close contact with the inside of the fixing hole, so that winding plate B is fixed, which makes it easier to adjust the position of winding plate B and improve the winding efficiency of copper wire.

[0018] (2) In the automobile drive motor core described in this utility model, after the winding plate B is adjusted, the ring sleeve A drives the support plate A to move, and the ring sleeve B drives the support plate B to move. Then, the ring sleeve A and the ring sleeve B respectively enter the symmetrically opened connecting slots on the winding plate A. Then, the magnetic block B in the connecting slot magnetically attracts the ring sleeve A and the ring sleeve B. Then, the support plate A on the ring sleeve A is stuck outside the winding plate A, and the support plate B outside the ring sleeve B is stuck outside the winding plate A. Then, the magnetic block A installed on the support plate A and the support plate B are magnetically connected, thereby improving the stability of the connection between the ring sleeve A and the ring sleeve B and the winding plate A respectively.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To improve the winding efficiency of copper wire, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses an automotive drive motor core, comprising a motor core body 1, a winding plate A2 symmetrically welded to the outside of the motor core body 1, and a winding plate B9 slidably connected to the inside of the winding plate A2. An arc plate 8 for winding copper wire is welded to the outside of the winding plate B9. A spring 20 is welded inside the winding plate A2, and a fixing rod 19 for fixing the winding plate B9 is inserted into the inside of the spring 20. Several fixing holes 5 are provided on the surface of the winding plate B9 to allow the fixing rod 19 to enter the interior of the winding plate B9. A rubber sleeve 22 is bonded to the outside of the fixing rod 19 and is tightly connected to the fixing hole 5. A connecting block 21 that drives the fixing rod 19 to move is welded to one side of the fixing rod 19. A ring sleeve A10 is inserted into the top of the winding plate A2, and a support plate A14 is welded to one side of the ring sleeve A10. A groove 13 is opened on the surface of the support plate A14 to relieve the pressure on the connecting block 21. A ring sleeve B18 is inserted into the bottom of the winding plate A2, and a support plate B17 is welded to one side of the ring sleeve B18. The surface of the winding plate B9 is symmetrically provided with scale lines 3 for precise adjustment of the position of the winding plate B9.

[0027] In use, when adjusting the winding plate B9, pull rings A10 and B18 outwards respectively. Then, ring A10 moves support plate A14, and ring B18 moves support plate B17. The groove 13 on support plate A14 moves to the outside of the connecting block 21 mounted on winding plate A2. Then, spring 20 inside winding plate A2 causes connecting block 21 to pop outwards, allowing it to enter groove 13. Then, fixing rod 19 on one side of connecting block 21 moves out of fixing hole 5 on winding plate B9. Since spring 20, fixing rod 19, and connecting block 21 are all provided in two sets inside winding plate A2, winding plate B9 is released from its fixed position. Then, pulling winding plate B9 outwards causes it to move out of winding plate A2. Observe the scale line 3 on the winding plate B9 to determine the position of the limit plate B. Then, press the ring A10 and ring B18 to move them. Ring A10 drives the support plate A14 to move, and ring B18 drives the support plate B17 to move. Then, the support plate A14 presses the connecting block 21 on the winding plate A2. The outer sides of the connecting block 21 are all tilted towards the center, so that the support plate A14 presses the connecting block 21 into the winding plate A2. Then, the spring 20 inside the winding plate A2 is compressed. Then, the connecting block 21 drives the fixing rod 19 into another fixing hole 5 opened on the winding plate B9. The rubber sleeve 22 outside the fixing rod 19 is in close contact with the inner side of the fixing hole 5, so that the winding plate B9 is fixed, which makes it easier to adjust the position of the winding plate B9 and improve the winding efficiency of copper wire.

[0028] To improve the stability of the connection between ring A10 and ring B18 and winding plate A2, for example, as follows: Figure 1 , Figure 2 As shown, the present invention also includes a connecting groove 12 symmetrically provided on the surface of the winding plate A2 to limit the ring sleeve A10 and the ring sleeve B18. A magnetic block B11 connected to the ring sleeve A10 is screwed on the inner side of the connecting groove 12. A magnetic block A16 is screwed on the outer side of the support plate A14 and the support plate B17.

[0029] During use, after the winding plate B9 is adjusted, the ring A10 drives the support plate A14 to move, and the ring B18 drives the support plate B17 to move. Then, the rings A10 and B18 enter the symmetrically opened connecting slots 12 on the winding plate A2. Subsequently, the magnetic block B16 in the connecting slot 12 magnetically attracts the rings A10 and B18. Then, the support plate A14 on the ring A10 is locked outside the winding plate A2, and the support plate B17 outside the ring B18 is locked outside the winding plate A2. Then, the magnetic block A11 installed on the support plate A14 and the support plate B17 are magnetically connected, thereby improving the stability of the connection between the rings A10 and B18 and the winding plate A2.

[0030] To improve the stability of the movement of the winding board B9, for example, such as Figure 1As shown, the present invention also includes a limiting groove 6 symmetrically formed on the surface of the winding plate A2, and a limiting block 7 connected to the winding plate B9 is slidably connected to the inner side of the limiting groove 6.

[0031] When in use, as the winding plate B9 moves within the winding plate A2, the limiting blocks 7 symmetrically welded to the outside of the winding plate B9 slide within the limiting grooves symmetrically opened on the winding plate A2, thereby improving the stability of the movement of the winding plate B9.

[0032] To prevent support plates A14 and B17 from detaching from the winding plate A2, for example, as follows: Figure 1 As shown, the present invention also includes a fixing block 15 symmetrically welded to the surface of the winding plate A2 to limit the positioning of the support plate A14 and the support plate B17.

[0033] When the support plates A14 and B17 move during use, the fixing blocks 15 symmetrically installed on the winding plate A2 limit the support plates A14 and B17 to prevent them from falling off the winding plate A2.

[0034] To prevent copper wires from shifting, for example, such as Figure 1 As shown, the present invention also includes, on the outside of the arc plate 8, symmetrical support blocks 4 are welded to prevent copper wires from shifting.

[0035] When in use, as the copper wire is wound around the outside of the arc plate 8, the support block 4 outside the arc plate 8 limits the copper wire to prevent it from shifting.

[0036] In use, when adjusting the winding plate B9, the rings A10 and B18 are pulled outwards. Ring A10 then moves the support plate A14, and ring B18 moves the support plate B17. The groove 13 on the support plate A14 moves to the outside of the connecting block 21 mounted on the winding plate A2. The spring 20 inside the winding plate A2 then pushes the connecting block 21 outwards, causing it to enter the groove 13. The fixing rod 19 on one side of the connecting block 21 then moves out of the fixing hole 5 on the winding plate B9. Since there are two sets of springs 20, fixing rods 19, and connecting blocks 21 inside the winding plate A2, the winding plate B9 is released from its fixed position. Then, the winding plate B9 is pulled outwards, and it moves from inside the winding plate A2. Observe the scale line 3 on the winding plate B9 to determine the position of the limit plate B. Then, press the ring A10 and ring B18 to move. Ring A10 drives the support plate A14 to move, and ring B18 drives the support plate B17 to move. Then, the support plate A14 presses the connecting block 21 on the winding plate A2. The outer sides of the connecting block 21 are all tilted towards the center, so that the support plate A14 presses the connecting block 21 into the winding plate A2. Then, the spring 20 in the winding plate A2 is compressed. Then, the connecting block 21 drives the fixing rod 19 into another fixing hole 5 opened on the winding plate B9. The rubber sleeve 22 outside the fixing rod 19 is in close contact with the inner side of the fixing hole 5, so that the winding plate B9 is fixed, which makes it easier to adjust the position of the winding plate B9 and improve the winding efficiency of copper wire.

[0037] After the winding plate B9 is adjusted, the ring A10 drives the support plate A14 to move, and the ring B18 drives the support plate B17 to move. Then, the rings A10 and B18 enter the symmetrically opened connecting slots 12 on the winding plate A2. Then, the magnetic block B16 in the connecting slot 12 magnetically attracts the rings A10 and B18. Then, the support plate A14 on the ring A10 is stuck outside the winding plate A2, and the support plate B17 outside the ring B18 is stuck outside the winding plate A2. Then, the magnetic block A11 installed on the support plate A14 and the support plate B17 are magnetically connected, thereby improving the stability of the connection between the rings A10 and B18 and the winding plate A2.

[0038] When the winding plate B9 moves inside the winding plate A2, the limiting blocks 7 symmetrically welded to the outside of the winding plate B9 slide within the limiting grooves symmetrically opened on the winding plate A2, thereby improving the stability of the movement of the winding plate B9.

[0039] When the support plate A14 and support plate B17 move, the fixing blocks 15 symmetrically installed on the winding plate A2 limit the support plate A14 and support plate B17 to prevent the support plate A14 and support plate B17 from falling off the winding plate A2.

[0040] When the copper wire is wound around the outside of the arc plate 8, the support block 4 outside the arc plate 8 limits the copper wire to prevent the copper wire from deviating.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
