Description

Technical Field

[0001] The present invention relates to the field of electric motors, and in particular to a mounting structure. Background Art

[0002] This invention describes a method for producing a modular frame and its stator. Compared to AC asynchronous motors, brushless DC motors offer advantages such as better controllability, a wider speed range, and higher efficiency, making them widely applicable to fan-type loads in household appliances. However, current brushless DC motor stators have the following structural issues:

[0003] First, there are many types of stator frames currently available. One electromagnetic solution uses one frame, which makes it inconvenient to modify the electromagnetic solution. In addition, each frame requires a corresponding mold, which is very expensive.

[0004] Second, the current stator frames are mostly assembled by combining shafts and holes. After assembly, glue is needed to prevent the frame from loosening. The greater the vibration of the motor, the greater the risk of the frame loosening.

[0005] Third, the winding taps are generally connected to the power cord by welding. The welding connection method faces the risk of cold soldering. After welding, an insulating sleeve is used to protect the solder joints to prevent sparks between the windings and cause the motor to burn out. This connection method has reliability risks and is inconvenient for employees to operate.

[0006] Fourth, when the winding tap is crimped and pierced in the air, it is deformed by stress and there is a risk of breaking or failure to pierce the paint. After being assembled into a motor, it is easy to cause burn-in or circuit breaker problems.

[0007] Fifth, the current stator frame upper frame assembly groove is fully "convex" or fully "concave", and the corresponding lower frame assembly groove is fully "concave" or fully "convex". Before assembly, it is necessary to distinguish the upper and lower frames first, and then put on the frames, which is inconvenient for employees to operate. Summary of the Invention

With the above arrangement, the mounting structure is divided into a base frame 2 and a segment frame 9. The base frame 2 can be universally used for stator cores 1 of the same type of motor, and the segment frame 9 is designed according to actual needs. One set of frames can be used for multiple electromagnetic solutions. If the electromagnetic solution requires significant modification, only the segment frame 9 needs to be redesigned. By designing the base frame 2 and segment frame 9, and combining the base frame 2 with different numbers and types of segment frames 9, one set of frames can be applied to multiple electromagnetic solutions, thereby improving the versatility of the mounting structure and solving the problem of poor versatility of the stator mounting structure of brushless DC motors in the prior art.

[0045] In the installation structure of this embodiment, see Figure 14 , a mounting groove 22 is provided on the mounting portion 21, and the block skeleton 9 is provided in the mounting groove 22; the winding 3 is arranged around the outside of the mounting groove 22; and / or, a mounting slide rail is provided on the mounting portion 21, and a mounting slider matching the mounting slide rail is provided on the block skeleton 9, and the mounting slider is inserted into the mounting slide rail.

[0046] In some embodiments, after the block frame 9 is installed on the base frame 2 , the connecting terminal 4 is installed in the terminal seat 93 of the block frame 9 .

[0047] See also Figures 7 to 11In the installation structure of this embodiment, the block skeleton 9 includes: a positioning plate 91, the positioning plate 91 is connected to the installation portion 21; a mounting block 92, the mounting block 92 is connected to the positioning plate 91; a terminal block 93, the terminal block 93 is connected to the end of the positioning plate 91 away from the mounting block 92, and the connecting terminal 4 is connected to the terminal block 93; wherein, two connecting strips 95 are respectively provided on opposite sides of the positioning plate 91, and the two connecting strips 95 are respectively used to connect the mounting block 92 and the terminal block 93. The above arrangement solves the problem of poor terminal crimping. The terminal block support boss is designed to support the winding tap, effectively reducing the risk of breaking or puncture failure when the winding tap is crimped to the terminal.

[0048] See also Figures 7 to 10 In the installation structure of this embodiment, a connecting groove 931 for installing the connecting terminal 4 is provided on the terminal seat 93; wiring grooves 932 are provided on the two opposite side walls of the connecting groove 931, and the wiring grooves 932 are connected to the connecting groove 931.

[0049] In the installation structure of this embodiment, see Figure 7 The terminal block 93 is provided with: a first support boss 933, the first support boss 933 is provided in the connecting groove 931, and the first support boss 933 is provided to protrude from the bottom of the connecting groove 931; and / or, a second support boss 934, the second support boss 934 is provided on the side of the terminal block 93 away from the positioning plate 91, the second support boss 934 extends in the direction of the terminal block 93 away from the positioning plate 91, and the wiring groove 932 is provided on the second support boss 934; and / or, there are multiple connecting grooves 931, and the multiple connecting grooves 931 are provided at intervals. With the above-mentioned setting, the block skeleton positioning plate 91 is designed, which can play a positioning role when assembled in the basic skeleton positioning groove. After winding, the enameled wire wraps the block skeleton positioning plate, which limits the freedom of the block skeleton.

[0050] See also Figures 12 to 13 In the mounting structure of this embodiment, the connecting terminal 4 includes: a first connecting plate 41, one end of the first connecting plate 41 is connected to the second connecting plate 42, the other end of the first connecting plate 41 is connected to the third connecting plate 43, and the second connecting plate 42 and the third connecting plate 43 are arranged at intervals; wherein, there are two first connecting plates 41, and there is an installation gap between the two first connecting plates 41, and an accommodating groove 44 is respectively provided on the second connecting plate 42 and the third connecting plate 43, and the accommodating groove 44 is communicated with the installation gap.

[0051] In the installation structure of this embodiment, see Figures 12 to 13The second connecting plate 42 and the third connecting plate 43 are each provided with two insertion portions 45, which are located on opposite sides of the receiving groove 44 on the second connecting plate 42 and the third connecting plate 43. The insertion portions 45 are used to be inserted into the block frame 9. The insertion portions 45 are respectively provided with a stopper 46, which is used to prevent the insertion portions 45 from falling out of the block frame 9. In this way, the problem of complicated grinding and soldering processes is solved. Crimping and piercing the terminal replaces the grinding and soldering processes, avoiding the hidden dangers of poor grinding and soldering during soldering.

[0052] See also Figure 13 In the installation structure of this embodiment, there are multiple connecting terminals 4, and the multiple connecting terminals 4 are arranged along a preset direction. The second connecting plates 42 on the multiple connecting terminals 4 are arranged at intervals, and the third connecting plates 43 on two adjacent connecting terminals 4 are connected to each other.

[0053] In the installation structure of this embodiment, see Figures 1 to 15 The basic frame 2 is an annular structure, and a plurality of mounting portions 21 are arranged around the basic frame 2; and / or, a positioning pin 23 is provided on the basic frame 2, and the positioning pin 23 is connected to the stator core 1.

[0054] See also Figures 1 to 15 In the installation structure of this embodiment, the basic skeleton 2 includes a first basic skeleton 201 and a second basic skeleton 202. The first basic skeleton 201 and the second basic skeleton 202 are respectively provided with a first connecting portion 24 and a second connecting portion 25. The first connecting portion 24 on the first basic skeleton 201 is connected to the second connecting portion 25 on the second basic skeleton 202, and the second connecting portion 25 on the first basic skeleton 201 is connected to the first connecting portion 24 on the second basic skeleton 202.

[0055] In the installation structure of this embodiment, see Figures 1 to 15 The first connecting portion 24 is inserted into the second connecting portion 25, and the first connecting portion 24 is provided with a connecting boss 241, which abuts the second connecting portion 25; and / or, there are multiple first connecting portions 24, and the multiple first connecting portions 24 are arranged at intervals; and / or, there are multiple second connecting portions 25, and the multiple second connecting portions 25 are arranged at intervals. In this way, the left side assembly groove of the base frame positioning pin is designed as a "convex" groove, and the right side assembly groove of the positioning pin is designed as a "concave" groove, so that the base frame can be used interchangeably without differentiation.

[0056] An embodiment of the installation structure of the present application is described below:

[0057] The stator assembly sequence of the mounting structure of this embodiment is as follows: first, a basic frame 2 is installed on the upper and lower sides of the stator core 1, and then the corresponding block frame 9 is assembled in the basic frame 2 according to the assembly requirements of the block frame 9; the centralized winding 3 is wound on the frame assembly with the assembled block frame 9, and the wound centralized winding 3 will lead out the winding U-phase head winding tap 31, V-phase head winding tap 32, W-phase head winding tap 33, U-phase tail winding tap 34, V-phase tail winding tap 35, and W-phase tail winding tap 36 on the frame assembly, and the winding taps are placed in the corresponding U-shaped slots of the block frame, as shown in FIG. Figure 5 The top view of the stator winding connection; finally, follow Figure 1 The stator overall assembly diagram is shown in FIG. 1 . The corresponding piercing terminal (ie, the connecting terminal 4 of this embodiment) is crimped into the terminal seat of the block skeleton to complete the production of the stator of this embodiment.

[0058] like Figure 7 As shown, the independent block skeleton 9 is composed of a "convex" mounting block 92, a block skeleton positioning plate 91, an independent block skeleton terminal seat 93 and a block skeleton connecting strip 95. Among them, a terminal connection groove 931 is provided on the top of the independent block skeleton terminal seat 93 for installing an independent piercing terminal; a terminal seat "U"-shaped groove (i.e., the wiring groove 932 of this embodiment) is provided on the front and back sides of the terminal connection groove 931, so that the winding tap can be placed in the center; a second terminal seat support boss 934 is provided outside the independent block skeleton terminal seat 93 and a first terminal seat support boss 933 is provided inside the terminal connection groove 931. The support boss is consistent in height with the bottom of the terminal seat "U"-shaped groove, which supports the winding tap and prevents the winding tap from being easily bent and deformed when the piercing terminal is crimped.

[0059] like Figure 9 、 Figure 10 As shown, the difference between the double-block skeleton 9 and the independent block skeleton 9 is that the independent block skeleton terminal seat 93 is replaced with the double-block skeleton terminal seat; similarly, the difference between the triple-block skeleton 9 and the independent block skeleton 9 is that the independent block skeleton terminal seat 93 is replaced with the triple-block skeleton terminal seat 93; and the difference between the ordinary block skeleton 9 and the independent block skeleton 9 is that the independent block skeleton terminal seat 93 is directly cancelled.

[0060] like Figure 10 As shown, the basic frame 2 has a "convex" groove on the tooth part, and a positioning plate mounting groove and a connecting rod mounting groove are opened at the tooth yoke connection. These grooves constitute the mounting groove 22 for installing the block frame 9. The effect after assembly is as follows Figure 2 and Figure 3The "convex" mounting block 92 of the block skeleton can move downward after being installed in the "convex" slot, but after the base skeleton 2 is assembled to the stator core 1, the stator core 1 can limit the downward movement of the "convex" mounting block 92; after the block skeleton's positioning plate 91 is installed in the positioning plate mounting slot, the block skeleton's positioning plate 91 is restricted from rotating forward, backward, left, right, up, and down, as well as moving forward, backward, left, right, and downward, and can only move upward. After the centralized winding 3 is wound, the winding will wrap around the tooth yoke connection of the base skeleton, and at the same time, it can limit the upward movement of the positioning plate 91 of the block skeleton. The base skeleton 2 is provided with 12 mounting slots 22, which can be adjusted with different block skeletons for different electromagnetic solutions.

[0061] like Figure 14 As shown, the basic frame positioning pin 23 is assembled to the stator core to play a positioning role. Figure 15 There is an assembly groove centerline on the basic frame assembly groove. The assembly groove within the assembly groove centerline is stretched downward to form a "convex" assembly groove (i.e., the first connecting portion 24 of this embodiment), and the assembly groove outside the assembly groove centerline is stretched downward to form a "concave" assembly groove (the second connecting portion 25). There are 6 "convex" assembly grooves distributed on the left side of the basic frame positioning pin 23, and 6 "concave" assembly grooves distributed on the right side of the basic frame positioning pin 23. The two basic frames 2 are assembled to the upper and lower sides of the stator core 1, and the basic frame positioning pins 23 are assembled into the positioning holes of the stator core 1. The "convex" assembly groove of the first basic frame 201 located above cooperates with the "concave" assembly groove of the second basic frame 202 located below; similarly, the "concave" assembly groove of the first basic frame 201 located above cooperates with the "convex" assembly groove of the second basic frame 202 located below. This design of the assembly groove allows the basic frames to be universally used up and down.

[0062] like Figure 4 From the stator winding sequence and wiring schematic, we know that 1U, 2V and 3W are common points, 10U is connected to the U phase power line, 11V is connected to the V phase power line, and 12W is connected to the W phase power line. Figure 2As shown, the assembly method of the puzzle skeleton 9 is as follows: a triple puzzle skeleton 9 is assembled at 2V of the first basic skeleton 201 located above, and the triple connection terminal 4 is subsequently crimped to connect 1U, 2V and 3W as a common point; then a double puzzle skeleton 9 is assembled at 11V of the first basic skeleton 201 located above, and two independent connection terminals 4 are subsequently crimped to connect the U-phase and V-phase power lines; then an independent puzzle skeleton 9 is assembled at 12W of the first basic skeleton 201 located above, and an independent connection terminal 4 is subsequently crimped to connect the W-phase power line; finally, ordinary puzzle skeletons 9 are installed in the remaining vacant puzzle skeleton 9 assembly slots of the first basic skeleton 201 located above, completing the assembly of the first basic skeleton 201 located above and the puzzle skeleton 9. The winding bridge wires (including the U-phase bridge wire 37, the V-phase bridge wire 38, and the W-phase bridge wire 39) are routed in the second basic frame 202 located below. No terminals are required during routing. Therefore, all the 12 assembly slots of the second basic frame 202 located below are equipped with ordinary block frames 9. The effect after assembly is as follows: Figure 3 shown.

[0063] according to Figure 4 The stator winding sequence and wiring schematic diagram are used for winding. One phase is wound by one wire. After winding, each winding tap is placed at the bottom of the "U"-shaped connection groove 931 of the terminal seat of the corresponding block skeleton 9 terminal seat. The effect after winding is as follows Figure 5 and Figure 6 shown.

[0064] like Figure 12 As shown, the independent connection terminal 4 is provided with an insertion portion 45 at the bottom, and a "U"-shaped groove is formed between the two insertion portions 45. The "U"-shaped groove can center the winding tap when crimping the terminal, and at the same time, the insertion portion 45 can cut through the outer paint of the winding tap to connect the terminal and the internal wire of the winding tap. A piercing terminal "V"-shaped boot is provided on each side of the insertion portion 45. This design can guide the terminal to smoothly enter the terminal connection groove 931 of the terminal seat when crimping the terminal. A piercing terminal triangular barb (i.e., a stop portion 46) is provided on the outside of the piercing terminal "V"-shaped boot. This structure can make the terminal easily enter the terminal connection groove 931 when crimping the terminal, but it is not easy to pull out after crimping. The upper part of the independent connection terminal 4 is an independent male terminal structure, which can be plugged into the female terminal of the same model; the lower part of the triple connection terminal 4 has the same structure as the independent connection terminal 4, and only the upper part connects the three independent terminals, such as Figure 12 The head of the triple piercing terminal is shown.

[0065] Finally, follow Figure 1 The independent connection terminal 4 and the triple connection terminal 4 are crimped into the corresponding terminal seats of the block frame 9 to complete the production of the stator of the present invention.

[0066] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0067] The mounting structure of the present invention includes a base frame 2, which is disposed within a stator core 1; a plurality of mounting portions 21 disposed on the base frame 2; the mounting portions 21 are used to mount windings 3; a plurality of segment frames 9, which are disposed one-to-one with the plurality of mounting portions 21; each segment frame 9 is connected to a corresponding mounting portion 21; and connection terminals 4, which can be selectively connected to the plurality of segment frames 9; the connection terminals 4 are used to connect wires and are connected to the windings 3. With the above arrangement, the mounting structure is divided into a base frame 2 and a segment frame 9. The base frame 2 can be universally used for stator cores 1 of the same type of motor, and the segment frame 9 is designed according to actual needs. One set of frames can be universally used for multiple electromagnetic solutions. If the electromagnetic solution requires significant modification, only the segment frame 9 needs to be redesigned. By designing the base frame 2 and the segment frame 9, and by combining the base frame 2 with different numbers and types of segment frames 9, one set of frames can be applied to multiple electromagnetic solutions, thereby improving the versatility of the mounting structure and solving the problem of poor versatility of the stator mounting structure of brushless DC motors in the prior art.

[0068] The mounting structure of the present invention greatly improves the versatility of the frame. The basic frame is suitable for the same type of stator core, and the block frame 9 is designed according to a commonly used electromagnetic scheme to be compatible with multiple electromagnetic schemes. If the electromagnetic scheme is significantly modified, only the block frame 9 needs to be redesigned to achieve universal compatibility, and the basic frame does not need to be modified.

[0069] The mounting structure of the present invention improves the reliability of frame assembly. The frame blocks 9 are positioned on the base frame using positioning plates to restrict radial and tangential movement, as well as radial, tangential, and axial rotation. During winding, the enameled wire wraps around the positioning plates of the frame blocks 9, thereby restricting axial movement and completely limiting the freedom of the frame blocks 9, making them less likely to come loose after assembly.

[0070] The crimped piercing terminals of the mounting structure of the present invention replace the welding connection method, which can improve the production efficiency of the stator and avoid hidden dangers such as unclean polishing, cold welding and inter-turn sparking.

[0071] The mounting structure of the present invention reduces the terminal crimping failure rate. The terminal support boss is designed to support the enameled wire, which can reduce the terminal crimping failure rate, improve the stator qualification rate, and reduce employee rework hours.

[0072] The mounting structure base frame 2 of the present invention does not require distinguishing between upper and lower frames before assembly. The left assembly slot of the base frame positioning pin is designed as a "convex" slot, and the right assembly slot of the positioning pin is designed as a "concave" slot, making the base frame universal. There is no need to distinguish between the upper and lower frames before assembly, which improves the versatility of the frames and facilitates employee operation.

[0073] The mounting structure of the present invention can effectively improve the versatility of the frame and the production efficiency of the stator.

They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0077] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0078] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0079] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
