Description

Technical Field

[0001] This utility model relates to stator plastic housings, specifically stator plastic housings with the function of adjusting the installation direction. Background Technology

[0002] In modern motor design, the molded housing is an important component of the stator assembly. Its main function is to introduce the copper wires of the stator coils and connect them to the external power supply lines through terminals on the housing. This design plays a crucial role in the overall structure of the motor.

[0003] In actual production, the motor rotor and motor stator are manufactured separately and need to be assembled by the manufacturer. However, different manufacturers have different assembly processes. When assembling the rotor concentrically at the center of the motor stator, there are two assembly methods: one is to assemble the rotor from the plastic shell end of the motor stator. In this case, in order to make room for the rotor, the plastic shell needs to be installed vertically on the motor stator; the other is to assemble from the end of the motor stator without the plastic shell. In this case, the plastic shell is installed horizontally on the motor stator.

[0004] Therefore, during production, it is necessary to produce two types of motor stators: one with a horizontally assembled plastic shell and the other with a vertically assembled plastic shell. This necessitates the design of two types of plastic shells, the opening of two production molds and corresponding production lines, which increases costs. Utility Model Content

[0005] In order to solve the problems in related technologies, this utility model provides a stator housing with an adjustable installation direction function. This device solves the problem that two stators need to be designed for different assembly methods of vertical and horizontal housings, which leads to increased costs.

[0006] To solve the above problems, the following technical solutions are provided:

[0007] A stator housing with adjustable installation direction includes a housing body mounted on a stator frame. The housing body has a fastener for connecting to the stator frame, and the fastener is detachably connected to the housing body. The housing body is mounted vertically or horizontally on the stator frame via the fastener.

[0008] With the above technical solution and the setting of the fixing parts, when the stator and rotor are delivered to the manufacturer for motor assembly after production, they can be directly assembled according to the actual assembly method or the installation direction of the plastic shell body can be adjusted before assembly. Thus, only one type of plastic shell body needs to be produced to meet the needs of different assembly methods of the manufacturer. Therefore, only one module needs to be made, and only one type of part needs to be managed on the production site, saving costs.

[0009] Furthermore, the fixing component includes a limiting component and a locking component; the plastic shell body is vertically mounted on the stator frame via the limiting component, or the plastic shell body is horizontally mounted on the stator frame via the locking component;

[0010] One end of the limiting member is fixedly disposed on the side wall of the plastic shell body, and the other end of the limiting member is provided with a first mounting hole. The first mounting hole is disposed along the width direction of the plastic shell body and is adapted to the positioning member on the stator frame.

[0011] The positioning component includes a positioning post and a positioning plate; the limiting component is provided in two types, namely a first limiting component and a second limiting component. The first limiting component is used to connect with the positioning post, and the second limiting component is used to connect with the positioning plate.

[0012] The first limiting component is a limiting post, and the first mounting hole on the limiting post is a round hole. The second limiting component is a limiting block, and the first mounting hole on the limiting block is a rectangular hole.

[0013] Through the above technical solution, by setting the first and second limiting components, when assembling the rotor and stator, when the rotor is assembled from the plastic shell end into the center of the stator, and the plastic shell body needs to be vertically installed on the stator frame, if the initial state of the plastic shell body on the stator is vertical, the rotor and stator can be directly assembled; if the initial state of the plastic shell body on the stator is horizontal, it is only necessary to first remove the plastic shell body from the stator, adjust the direction of the plastic shell body so that the first mounting holes on the first and second limiting components are aligned with the positioning posts and positioning plates on the stator frame, and then press down the plastic shell body to complete the quick positioning and stable installation. When disassembling the plastic shell body, simply pull it outward to pull the positioning posts and positioning plates on the stator frame out of the first and second limiting components. The entire disassembly and assembly process does not require additional disassembly tools, the structure is simple and the operation is quick, effectively improving the convenience of motor assembly and maintenance; and by setting two different limiting components, the installation position and direction of the plastic shell can be quickly determined, realizing the orientation of the assembly, which is convenient and fast.

[0014] Furthermore, the clip is fixedly disposed on the side wall of the plastic shell body, and the clip is provided with a second mounting hole for engaging with the clip block of the stator frame. The second mounting hole is a through hole and is disposed along the thickness direction of the plastic shell body.

[0015] The positioning plates are provided in three parts, extending upward along the axial direction of the stator frame, and the locking blocks are provided on the outer wall surfaces of two adjacent positioning plates on the stator frame.

[0016] With the above technical solution, by setting the second mounting hole, when the rotor is assembled into the stator center from the non-plastic shell end and the plastic shell body needs to be installed horizontally on the stator, if the plastic shell body is installed vertically at this time, then it is only necessary to first remove the plastic shell body from the stator, adjust the direction of the plastic shell body so that the second mounting hole is aligned with the locking block, and then press the plastic shell body down so that the section containing the locking block is locked in the second mounting hole to complete the fixation. The structure is simple and the operation is quick, thereby realizing the fixed connection between the plastic shell body and the stator, thus ensuring the stability of the plastic shell in the horizontal installation state.

[0017] Further, the stator frame is a plastic stator frame; the second mounting hole includes a first notch, a second notch, and a third notch; when the plastic shell is arranged horizontally by the clip, the first notch is located at the bottom of the clip, the first notch is adapted to the corresponding section of the positioning plate containing the clip block, the second notch is located in the upper middle part of the clip and communicates with the first notch, the length of the second notch along the radial direction of the stator frame is less than the length of the first notch, and the side wall surface of the second notch away from the stator frame coincides with the side wall surface of the first notch away from the stator frame, the third notch is located in the upper part of the side wall surface of the clip near the clip block and communicates with the second notch, and the bottom of the third notch is located below the top of the first notch.

[0018] Through the above technical solution, by setting the first, second, and third notches, when the plastic shell body needs to be horizontally installed on the stator, the first notch is aligned with the corresponding positioning plate containing the locking block and pressed down. At this time, both the locking block and the positioning plate can pass through the first notch. After the upper part of the positioning plate passes through the first notch, it will enter the second notch. At this time, as the plastic shell body moves down, the locking block also begins to enter the second notch. At this time, the upper part of the positioning plate will be subjected to the force of the side wall surface corresponding to the center of the stator frame in the second notch, causing the positioning plate to move away from the center of the stator frame. Since the stator frame is a plastic part, the locking block can pass through the second notch and enter the third notch. The bottom of the locking block is lower than the locking piece corresponding to the bottom of the third notch. Thus, after the plastic shell body is horizontally installed, the stability of the connection between the locking piece and the stator frame is improved.

[0019] The above solution has the following advantages:

[0020] 1. By setting up the fixing parts, when the stator and rotor are delivered to the manufacturer for motor assembly after production, they can be directly assembled according to the actual assembly method or the installation direction of the plastic shell body can be adjusted before assembly. Thus, only one type of plastic shell body needs to be produced to meet the needs of different assembly methods of the manufacturer. Therefore, only one module needs to be made, and only one type of part needs to be managed on the production site, saving costs.

[0021] 2. With the setting of the first and second limiting components, when assembling the rotor and stator, if the initial state of the plastic shell body on the stator is vertical, the rotor and stator can be directly assembled when the rotor is assembled from the plastic shell end into the center of the stator. If the initial state of the plastic shell body on the stator is vertical, the plastic shell body can be directly assembled. If the initial state of the plastic shell body on the stator is horizontal, the plastic shell body only needs to be removed from the stator first, and the direction of the plastic shell body should be adjusted so that the first mounting holes on the first and second limiting components are aligned with the positioning posts and positioning plates on the stator frame, respectively. Then, the plastic shell body can be pressed down to complete the quick positioning and stable installation. When disassembling the plastic shell body, simply pull it outward to pull the positioning posts and positioning plates on the stator frame out of the first and second limiting components. The entire disassembly and assembly process does not require additional disassembly tools. The structure is simple and the operation is quick, effectively improving the convenience of motor assembly and maintenance. Moreover, by setting two different limiting components, the installation position and direction of the plastic shell can be quickly determined, realizing the orientation of the assembly, which is convenient and fast.

[0022] 3. With the second mounting hole, when the rotor is assembled into the stator center from the non-molded shell end and the molded shell body needs to be installed horizontally on the stator, if the molded shell body is installed vertically at this time, then you only need to remove the molded shell body from the stator first, adjust the direction of the molded shell body so that the second mounting hole is aligned with the locking block, and then press the molded shell body down so that the section containing the locking block is locked into the second mounting hole to complete the fixation. The structure is simple and the operation is quick, thereby realizing the fixed connection between the molded shell body and the stator, thus ensuring the stability of the molded shell in the horizontal installation state.

[0023] 4. By setting the first, second, and third notches, when the plastic shell body needs to be installed horizontally on the stator, align the first notch with the positioning plate containing the locking block and press it down. At this time, both the locking block and the positioning plate can pass through the first notch. After the upper part of the positioning plate passes through the first notch, it will enter the second notch. As the plastic shell body moves down, the locking block also begins to enter the second notch. At this time, the upper part of the positioning plate will be subjected to the force of the side wall surface corresponding to the center of the stator frame in the second notch, causing the positioning plate to move away from the center of the stator frame. Since the stator frame is a plastic part, the locking block can pass through the second notch and enter the third notch. The bottom of the locking block is lower than the locking piece corresponding to the bottom of the third notch, thus improving the stability of the connection between the locking piece and the stator frame after the plastic shell body is installed horizontally.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Specific embodiment 1, such as Figure 1-6The stator housing with adjustable installation direction includes a housing body 2 mounted on the stator frame 1. The housing body 2 has fasteners for connecting to the stator frame 1, and the fasteners are detachably connected to the housing body 2. The housing body 2 is mounted vertically or horizontally on the stator frame 1 through the fasteners. With the fasteners, when the stator and rotor are delivered to the manufacturer for motor assembly after production, they can be directly assembled according to the actual assembly method or the installation direction of the housing body 2 can be adjusted before assembly. Thus, only one type of housing body 2 needs to be produced to meet the needs of different assembly methods of the manufacturer. Therefore, only one module needs to be developed, and only one type of part needs to be managed on the production site, saving costs.

[0036] like Figure 2 As shown, the fasteners include limiting components and locking components 14; the plastic shell body 2 is vertically mounted on the stator frame 1 via the limiting components, or the plastic shell body 2 is horizontally mounted on the stator frame 1 via the locking components 14.

[0037] One end of the limiting member is fixedly mounted on the side wall of the plastic shell body 2, and the other end of the limiting member is provided with a first mounting hole 5. The first mounting hole 5 is provided along the width direction of the plastic shell body 2, and the first mounting hole 5 is adapted to the positioning member on the stator frame 1; just as Figure 1 The three-dimensional coordinate system shown has the x-axis as the length direction of the plastic shell body 2, the y-axis as the thickness direction of the plastic shell body 2, and the z-axis as the width direction of the plastic shell body 2.

[0038] like Figure 2 and Figure 5As shown, the positioning component includes a positioning post 6 and a positioning plate 7; there are two types of limiting components, namely a first limiting component 3 and a second limiting component 4. The first limiting component 3 is used to connect with the positioning post 6, and the second limiting component 4 is used to connect with the positioning plate 7. In this specific embodiment 1, the first limiting component 3 is a limiting post, and the first mounting hole 5 on the limiting post is a round hole. The second limiting component 4 is a limiting block, and the first mounting hole 5 on the limiting block is a rectangular hole. When assembling the rotor and stator, when the rotor is assembled into the center of the stator from the plastic shell end, it is necessary to vertically install the plastic shell body 2 on the stator frame 1. If the initial state of the plastic shell body 2 on the stator is vertical, the rotor and stator can be directly assembled. If the initial state of the plastic shell body 2 on the stator is vertical, the rotor and stator can be directly assembled. Initially, the shell body 2 is horizontal. At this point, simply remove the shell body 2 from the stator, adjust its orientation so that the first mounting holes 5 on the first limiting member 3 and the second limiting member 4 are aligned with the positioning post 6 and the positioning plate 7 on the stator frame 1, respectively. Then, press down the shell body 2 to complete the quick positioning and stable installation. When disassembling the shell body 2, simply pull it outward to remove the positioning post 6 and the positioning plate 7 on the stator frame 1 from the first limiting member 3 and the second limiting member 4. The entire disassembly and assembly process does not require additional disassembly tools. The structure is simple and the operation is quick, effectively improving the convenience of motor assembly and maintenance. Furthermore, by setting two different limiting members, the installation position and direction of the shell can be quickly determined, achieving correct assembly orientation, which is convenient and fast.

[0039] like Figure 1 As shown, the plastic housing body 2 has a wire groove inside, and the plastic housing body 2 has a terminal block 12 and a wire inlet hole 13 communicating with the wire groove. The wire inlet hole 13 is located at one end of the length direction of the plastic housing body 2, and the terminal block 12 is fixedly located on the end face between the two side walls in the width direction of the plastic housing body 2. The terminal block 12 and the wire inlet hole 13 are both conventional designs of the plastic housing body 2, and will not be described in detail here. In this specific embodiment, there are three terminal blocks 12, which are used for connecting the three-phase lines U, V and W respectively. When the three terminal blocks 12 of the three-phase lines are all standard parts, the outer diameter of each terminal block 12 is greater than 110mm and the inner diameter is greater than 65mm.

[0040] Specific embodiment 2, such as Figure 1-5 and Figure 7As shown, the difference between this specific embodiment 2 and specific embodiment 1 is that in this specific embodiment 2, the plastic shell body 2 is horizontally mounted on the stator frame 1 by means of a clip 14. The clip 14 is fixedly set on the side wall of the plastic shell body 2, and the clip 14 is provided with a second mounting hole for engaging with the clip block 8 of the stator frame 1. The second mounting hole is a through hole and is set along the thickness direction of the plastic shell body 2. When the rotor is assembled into the center of the stator from the non-plastic shell end and the plastic shell body 2 needs to be horizontally mounted on the stator, if the plastic shell body 2 is vertically mounted at this time, then it is only necessary to first remove the plastic shell body 2 from the stator, adjust the direction of the plastic shell body 2 so that the second mounting hole is aligned with the clip block 8, and then press the plastic shell body 2 down so that the section containing the clip block 8 is engaged in the second mounting hole to complete the fixation. The structure is simple and the operation is quick, thereby realizing the fixed connection between the plastic shell body 2 and the stator, thus ensuring the stability of the plastic shell in the horizontal installation state.

[0041] like Figure 2 , Figure 5 and Figure 7-8 As shown, the locking block 8 is set on the outer wall of the positioning plate 7 on the stator frame 1. There are three positioning plates 7, which extend upward along the axial direction of the stator frame 1. The locking block 8 is set on the outer wall of two adjacent positioning plates 7 on the stator frame 1.

[0042] Stator frame 1 is a plastic stator frame; the second mounting hole includes a first notch 9, a second notch 10, and a third notch 11; the first notch 9, the second notch 10, and the third notch 11 are interconnected, as shown in the figure below for ease of description. Figure 8 As shown, the three are separated by dotted lines. When the plastic shell is arranged horizontally by the clip 14, the first notch 9 is located at the bottom of the clip 14 and is adapted to the corresponding positioning plate containing the clip 8. The second notch 10 is located in the upper middle part of the clip 14 and is connected to the first notch 9. The length of the second notch 10 along the radial direction of the stator frame 1 is less than the length of the first notch 9, and the side wall of the second notch 10 away from the stator frame 1 coincides with the side wall of the first notch 9 away from the stator frame 1. The third notch 11 is located in the upper part of the side wall of the clip 14 near the clip 8 and is connected to the second notch 10. The bottom of the third notch 11 is located below the top of the first notch 9.

[0043] When the plastic shell body 2 needs to be installed horizontally on the stator, align the first notch 9 with the positioning plate containing the locking block 8 and press it down. At this time, both the locking block 8 and the positioning plate can pass through the first notch 9. After the upper part of the positioning plate passes through the first notch 9, it will enter the second notch 10. At this time, as the plastic shell body 2 moves down, the locking block 8 also begins to enter the second notch 10. At this time, the upper part of the positioning plate will be subjected to the force of the side wall surface corresponding to the center of the stator frame 1 in the second notch 10, causing the positioning plate to move away from the center of the stator frame 1. Since the stator frame 1 is a plastic part, the locking block 8 can pass through the second notch 10 and enter the third notch 11. The bottom of the locking block 8 abuts against the wall surface of the locking piece 14 corresponding to the bottom of the third notch 11, thus improving the stability of the connection between the locking piece 14 and the stator frame 1 after the plastic shell body 2 is installed horizontally.

[0044] Operating Procedure: When the rotor is installed into the stator center from the plastic shell end, the plastic shell body needs to be installed vertically onto the stator frame. Align the first mounting holes on the first and second limiting members with the positioning posts and positioning plates on the stator frame, respectively, and then press down on the plastic shell body to complete the installation. When the rotor is installed into the stator center from the non-plastic shell end, the plastic shell body needs to be installed horizontally onto the stator frame, aligning the second mounting hole with the locking block 8. After alignment, press down on the plastic shell body 2 so that the section containing the locking block 8 engages in the second mounting hole to complete the fixation.
