Description

Technical Field

[0001] The present invention relates to the technical field of motor housings, and specifically to a straight-chain type automatic wire-straightening housing structure. Background Art

[0002] In the production of straight-chain motors, the stator group generally consists of skeletons connected in a chain. Generally, wire-passing grooves for wire arrangement are also provided on the outer end faces of the skeletons. In order to facilitate wire threading, wire grooves are also provided on the skeletons. The skeletons can refer to the insulating skeletons, stators having the same, and stator assembly methods disclosed in Patent Publication No. CN106160275A.

[0003] The design of the existing housing only wraps the skeletons. In the production of straight-chain motors, after the outer diameters of the stator cores are rolled and linked together, the cross-over wires outside the upper skeletons will become loose or bulged, and are easily wound around other wires, affecting the working performance of the motor. The existing method is to manually straighten the messy wires one by one, which is time-consuming and laborious and is not conducive to improving production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a straight-chain type automatic wire-straightening housing structure to solve the problems existing in the prior art.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] The straight-chain type automatic wire-straightening housing structure includes a housing covering one end after the straight-chain skeleton is rolled. The top of the skeleton has a wire-walking support portion that cooperates with the housing. Wire grooves are provided on the outer wall of the wire-walking support portion along the circumferential direction. The feature is that a wire groove is axially opened on the wire-walking support portion, and the wire groove is communicated with the wire groove. A wire-straightening portion is provided on the housing, and the wire-straightening portion is used to press the wire radially into the wire groove.

[0007] In the above solution, the wire grooves and wire grooves are provided on the wire-walking support portion to realize the arrangement and storage of the wires, so that the wires are distributed along the wire grooves and wire grooves. As the wire-straightening portion presses the wires, the wires are closely attached to the wire grooves and the redundant parts of the wires are stored in the wire grooves, forming an effect of automatic wire arrangement, and effectively avoiding the situations such as shaking and displacement of the wires during the operation of the equipment, improving the stability of the wire arrangement, and ensuring the normal operation of the equipment.

[0008] Further, there are three parallel wire grooves on the wire routing support part. Adjacent three wire routing support parts form a group and are connected end to end. In each group, the wire grooves correspond to the wire routing grooves one by one to form three wire grooves with different depths. The wire straightening part includes a wire straightening block that cooperates with one or two of the guiding grooves in some groups of guiding grooves, and the wire straightening block does not cooperate with the guiding groove with the shallowest depth. The wire straightening block is fixedly arranged on the inner wall of the housing. When the housing is combined with the wire routing support part, the wire straightening block is located at the wire groove and presses the wire from the radially outer side of the wire groove to the radially inner side.

[0009] In the above solution, three parallel wire routing grooves, the wire grooves corresponding to the wire routing grooves, and the wire straightening block corresponding to the deepest wire groove in some groups of wire grooves or two wire grooves except the shallowest one are provided, so that the housing structure can process multiple wires at the same time, meet the daily use requirements of the motor, and according to the different depths of the wire grooves and the cooperation of the wire straightening blocks, the wires in the highest wire routing groove or the two higher wire routing grooves can be respectively pressed and fixed, improving the efficiency and neatness of wire arrangement.

[0010] Further, the wire straightening block is arranged between the top wall and the side wall inside the housing. The bottom of the wire straightening block has an inclined surface, and the distance from a point on the inclined surface perpendicular to the center line of the housing from top to bottom increases from short to long.

[0011] In the above solution, when the housing is combined with the wire routing support part, the inclined surface at the bottom of the wire straightening block can gradually apply a pressing force to the wire, so that the wire straightening block gradually presses the wire into the wire groove. This progressive pressing method can avoid suddenly applying too much pressure to the wire and damaging the wire. At the same time, it is also beneficial to automatically adjust the position of the wire during the installation process, make the wire enter the wire groove more smoothly and be pressed, improving the convenience and reliability of installation.

[0012] Further, the cross-sectional line of the inclined surface is a straight line, an arc or a wavy line.

[0013] [[ID=IS]]In the above solution, the appropriate shape of the inclined surface of the wire straightening block can be selected according to different actual use scenarios, providing flexibility for the housing and meeting the wire arrangement requirements of different use scenarios.

[0014] Further, each group of the wire grooves includes a first wire groove, a second wire groove and a third wire groove in order from shallow to deep; the three parallel wire routing grooves include a high wire routing groove, a middle wire routing groove and a low wire routing groove arranged in order from high to low; the high wire routing groove is communicated with the first wire groove, the high wire routing groove and the middle wire routing groove are communicated with the second wire groove, and the high wire routing groove, the middle wire routing groove and the low wire routing groove are communicated with the third wire groove; the wire straightening block includes a first wire straightening block and a second wire straightening block arranged from short to long and adapted to the second wire groove and the third wire groove.

[0015] In the above solution, wire grooves of different depths cooperate with wire-straightening blocks of corresponding lengths, enabling targeted pressing and fixing of wires at different height positions. That is, the second wire groove is deeper than the first wire groove but shallower than the third wire groove, and the corresponding first wire-straightening block is shorter, which can properly fix the wires at the middle height position; the third wire groove is the deepest, and the second wire-straightening block is the longest, which can better press the wires at the high position, thereby improving the refinement degree of organizing and fixing multiple wires at different positions, reducing the mutual interference between wires, and enhancing the stability of the overall wire installation.

[0016] Further, the first wire-straightening block has a first inclined surface, and the second wire-straightening block has a second inclined surface. The angle between the first inclined surface and the horizontal plane is 60°, and the angle between the second inclined surface and the horizontal plane is 75°.

[0017] In the above solution, the first inclined surface and the second inclined surface are set to be inclined at different degrees. The second wire-straightening block with a larger inclination angle, such as 75° for the second inclined surface, can generate a relatively gentle pressing force on the wires in the high wire groove, avoiding excessive extrusion of the wires and ensuring the safety and stability of the wires during the fixing process.

[0018] Further, a first anti-top block is provided at the bottom of the first wire groove, a second anti-top block is provided at the bottom of the second wire groove, and a third anti-top block is provided at the bottom of the third wire groove. The first anti-top block, the second anti-top block, and the third anti-top block are respectively arranged on the radial outer sides of the first wire groove, the second wire groove, and the third wire groove.

[0019] In the above solution, the setting of the first anti-top block, the second anti-top block, and the third anti-top block can increase the insulation distance between the flying wires on the skeleton, thereby improving the insulation effect of the present invention.

[0020] Further, the cover shell includes an annular top wall. On both the inner and outer sides of one side of the top wall, there are respectively provided annular first cover walls and second cover walls. The top wall abuts against the top end of the wire-walking support part. There is a gap between the bottom end of the first cover wall and the top end inside the skeleton. The second cover wall is fixedly clamped with the outer end face of the wire-walking support part.

[0021] In the above solution, the cover shell has an annular top wall, a first cover wall, and a second cover wall, forming a groove structure through the top wall, the first cover wall, and the second cover wall, enabling it to closely cover the skeleton. The top wall abuts against the top end of the wire-walking support part, providing stable support for the entire cover shell; the gap design between the bottom end of the first cover wall and the top end inside the skeleton can not only avoid interference with the internal structure of the skeleton but also provide a certain degree of lateral protection for the wires; the clamping and fixing method of the second cover wall with the outer end face of the wire-walking support part facilitates the installation and disassembly of the cover shell, is convenient for equipment maintenance and repair, and also ensures the connection reliability between the cover shell and the skeleton during normal operation.

[0022] Further, a wire threading platform and a wire routing opening are provided on the top wall. Three wire threading openings are provided on the wire threading platform. The wire routing openings are evenly distributed in a ring on the top wall. A wire bundling rack is further provided on the top wall near the wire threading platform.

[0023] In the above solution, the wire threading platform and the multiple wire threading openings are provided, so that the three-phase wires of the coil winding can enter the wire threading platform from one end of the wire threading platform respectively, and are connected to external wires through the three wire threading openings, thereby improving the neatness of the three-phase wires and facilitating maintenance.

[0024] Further, at least one clamping block is provided on the outer end surface of the wire routing support portion, and a card slot corresponding to the clamping block is opened at the bottom of the second cover wall.

[0025] In the above solution, the clamping block on the outer end surface of the wire routing support portion corresponds to the card slot at the bottom of the second cover wall, realizing the precise positioning and rapid connection between the cover shell and the skeleton.

[0026] Adopting the above solution, the following advantages are specifically available:

[0027] 1. The straight-chain type automatic wire-straightening cover shell structure of the present invention includes a cover shell covering one end after the circular rolling of the chain-type skeleton. The top of the skeleton has a wire routing support portion matching with the cover shell. A wire routing groove is arranged on the outer wall of the wire routing support portion along the circumferential direction. A wire guiding groove is axially opened on the wire routing support portion. The wire routing groove is communicated with the wire guiding groove. A wire-straightening portion is provided on the cover shell. The wire-straightening portion is used to press the wire tightly into the wire guiding groove along the radial direction. The wire routing groove and the wire guiding groove are arranged on the wire routing support portion to realize the sorting and storage of the wire, so that the wire is distributed along the wire routing groove and the wire guiding groove. With the pressing of the wire by the wire-straightening portion, the wire is tightly attached to the wire routing groove and the redundant part of the wire is stored in the wire guiding groove, forming an effect of automatic wire arrangement, and effectively avoiding the situations such as shaking and displacement of the wire during the operation of the equipment, improving the stability of the wire arrangement, and ensuring the normal operation of the equipment.

[0028] 2. The wire routing support part has three parallel wire routing grooves. Three adjacent wire routing support parts form a group and are connected end to end. In each group, the wire grooves correspond to the wire routing grooves one by one to form three wire grooves with different depths. The wire straightening part includes a wire straightening block that cooperates with one or two of the guiding grooves in some groups of guiding grooves, and the wire straightening block does not cooperate with the guiding groove with the shallowest depth. The wire straightening block is fixed on the inner wall of the housing. When the housing is combined with the wire routing support part, the wire straightening block is located at the wire groove to press the wire inward from outside the wire groove. By setting three parallel wire routing grooves, the corresponding wire grooves, and the wire straightening block corresponding to the deepest one of the wire grooves in some groups or the two wire grooves except the shallowest one, this housing structure can process multiple wires simultaneously, meet the daily use requirements of the motor, and can press and fix the wires in the highest wire routing groove or the two higher wire routing grooves respectively according to the different depths of the wire grooves and the cooperation of the wire straightening block, improving the efficiency and neatness of wire arrangement.

Specific embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figure 1 and 2 shown, the straight-chain type automatic wire straightening housing structure of this embodiment includes a housing 1 covering one end of the coiled circular chain-type skeleton 2. The top of the skeleton 2 has a wire routing support portion that cooperates with the housing 1. The skeleton 2 is integrally injection-molded on the stator core or is inserted into the skeleton at both ends in the axial direction of the stator core. As an example, this embodiment uses a three-phase motor stator winding for application. In order to adapt to the three-phase motor stator winding, the skeleton 2 in this embodiment is a skeleton 2 integrally injection-molded on the stator core;

[0043] A wire routing groove 204 is provided on the outer wall of the wire routing support portion along the circumferential direction. A wire groove is axially opened on the wire routing support portion. The wire routing groove 204 is communicated with the wire groove. A wire straightening portion is provided on the housing 1. The wire straightening portion is used to press the wire radially into the wire groove;

[0044] There are three parallel wire routing grooves 204 on the wire routing support portion. Adjacent three wire routing support portions are in a group and are connected end to end. In each group, the wire grooves and the wire routing grooves 204 correspond one by one to form three wire grooves with different depths. The wire straightening portion includes a wire straightening block 3 that cooperates with one or two of the guiding grooves in some groups of guiding grooves, and the wire straightening block 3 does not cooperate with the guiding groove with the shallowest depth. The wire straightening block 3 is fixedly provided on the inner wall of the housing 1. When the housing 1 is combined with the wire routing support portion, the wire straightening block 3 is located at the wire groove to press the wire from the radially outer side of the wire groove to the radially inner side;

[0045] By providing three parallel wire grooves 204, a wire guide groove corresponding to the wire groove 204, and a wire straightening block 3 corresponding to the deepest one of the partial wire guide grooves or two wire guide grooves other than the shallowest one, the housing structure can process multiple wires simultaneously, meeting the daily use requirements of the motor. Moreover, according to the different depths of the wire guide grooves and the cooperation of the wire straightening block 3, each wire can be separately pressed and fixed, improving the efficiency and tidiness of wire arrangement.

[0046] To ensure the strength of the wire straightening block 3, the wire straightening block 3 can be arranged between the top wall 101 and the side wall inside the housing, that is, the wire straightening block 3 is fixedly connected to both the top wall 101 and the side wall inside the housing; a slope is also provided at the bottom of the wire straightening block 3. When the housing is combined with the wire routing support portion, the slope at the bottom of the wire straightening block 3 can gradually apply a pressing force to the wire, enabling the wire straightening block 3 to gradually press the wire into the wire guide groove. This progressive pressing method can avoid suddenly applying excessive pressure to the wire and damaging the wire. At the same time, it is also beneficial for automatically adjusting the position of the wire during the installation process, enabling the wire to enter the wire guide groove more smoothly and be pressed, improving the convenience and reliability of installation.

[0047] In this embodiment, the cross-sectional line of the slope can be selected as a straight line, an arc, or a wavy line. By selecting a suitable slope shape of the wire straightening block 3 in different actual use scenarios, the flexibility of the housing is ensured, and the wire management requirements for different use scenarios are met.

[0048] Specifically, for another example Figure 2 As shown, each group of wire guide grooves in this embodiment includes a first wire guide groove 201, a second wire guide groove 202, and a third wire guide groove 203 arranged in ascending order of depth; the three parallel wire grooves include a high wire groove, a medium wire groove, and a low wire groove arranged in descending order; the high wire groove is communicated with the first wire guide groove 201, the high wire groove and the medium wire groove are communicated with the second wire guide groove 202, and the high wire groove, the medium wire groove, and the low wire groove are communicated with the third wire guide groove 203; and the wire straightening block 3 also includes a first wire straightening block 301 and a second wire straightening block 302 arranged from short to long and adapted to the second wire guide groove 202 and the third wire guide groove 203;

[0049] As Figures 6-7 shown, the wire has been wound along the wire grooves on the wire routing support portion. Now, the housing 1 is assembled at one end of the axial center after the chain-type skeleton 2 is curled. During the assembly process, the first wire straightening block 301 and the second wire straightening block 302 gradually approach the wire on the wire groove; when the assembly is completed, as Figures 8-10 shown, the first wire straightening block 301 and the second wire straightening block 302 respectively firmly abut against the corresponding wire.

[0050] The wire grooves with different depths cooperate with the wire-straightening blocks 3 of corresponding lengths, which can tightly fix the wires at different height positions in a targeted manner. That is, the second wire groove 202 is deeper than the first wire groove 201 but shallower than the third wire groove 203. The corresponding first wire-straightening block 301 is short, which can properly fix the wires at the middle height position. The third wire groove 203 is the deepest, and the second wire-straightening block 302 is long, which can better press and fix the wires at the high position. Thus, the refinement degree of organizing and fixing multiple wires at different positions is improved, the mutual interference between wires is reduced, and the overall installation stability of the wires is enhanced.

[0051] The first wire-straightening block 301 has a first inclined surface 3011, and the second wire-straightening block 302 has a second inclined surface 3021. The included angle between the first inclined surface 3011 and the horizontal plane is 60°, and the included angle between the second inclined surface 3021 and the horizontal plane is 75°. The first inclined surface 3011 and the second inclined surface 3021 are set to be inclined at different degrees. The second wire-straightening block 302 with a larger inclined angle, such as 75° in the second inclined surface 3021, can gently press the wires in the high wire groove, avoiding the wire breakage problem caused by quickly pressing the wires into the third wire groove 203, and ensuring the safety and stability of the wires during the fixing process.

[0052] During the production process of the new energy vehicle air-conditioning compressor motor, a commonly used housing in the market is selected to produce the motor. The commonly used housing means that the first wire-straightening block 301 and the second wire-straightening block 302 in this embodiment are not provided inside the housing. At this time, the defective rate of the produced motor is usually 1% - 5%, and the annual failure rate of the motor body is usually 1% - 3%.

[0053] When the first wire-straightening block 301 and the second wire-straightening block 302 are arranged from short to long on the housing, but the first inclined surface 3011 is not provided on the first wire-straightening block 301, and the second inclined surface 3021 is not provided on the second wire-straightening block 302, the defective rate of the produced motor is reduced by 0.5% - 1% compared with the defective rate of the existing motor, and the annual failure rate of the motor body is reduced to 0.6% - 0.8% compared with the annual failure rate of the existing motor.

[0054] When the first wire-straightening block 301 and the second wire-straightening block 302 are arranged from short to long on the housing, and the first inclined surface 3011 is provided on the first wire-straightening block 301 inside the housing, and the second inclined surface 3021 is provided on the second wire-straightening block 302, the defective rate of the produced motor is reduced by 1% - 1.5% compared with the defective rate of the existing motor, and the annual failure rate of the motor body is reduced to 0.4% - 0.6% compared with the annual failure rate of the existing motor.

[0055] In summary, from the experimental data, when the first wire-straightening block 301 and the second wire-straightening block 302 with different lengths are provided on the housing, the produced motor has better performance in terms of the defective rate and the annual failure rate compared with the existing motors. When the first wire-straightening block 301 and the second wire-straightening block 302 with different lengths are provided on the housing, and the first inclined surface 3011 and the second inclined surface 3021 are respectively provided on the first wire-straightening block 301 and the second wire-straightening block 302, the produced motor has the best performance in terms of the defective rate and the annual failure rate.

[0056] A first anti-top block 2011 is further provided at the bottom of the first wire groove 201, a second anti-top block 2021 is further provided at the bottom of the second wire groove 202, and a third anti-top block 2031 is further provided at the bottom of the third wire groove 203. The first anti-top block 2011, the second anti-top block 2021 and the third anti-top block 2031 are respectively provided on the radial outer sides of the first wire groove 201, the second wire groove 202 and the third wire groove 203. By providing the first anti-top block 2011, the second anti-top block 2021 and the third anti-top block 2031, the insulation distance between the flying wires on the skeleton 2 can be increased, thereby improving the insulation effect of the present invention.

[0057] As Figure 4 shown, the housing includes an annular top wall 101. On both the inner and outer sides of one side of the top wall 101, an annular first cover wall 102 and a second cover wall 103 are respectively provided. The top wall 101 abuts against the top end of the wire-walking support portion. A gap is left between the bottom end of the first cover wall 102 and the top end inside the skeleton 2. The second cover wall 103 is fixedly connected to the outer end face of the wire-walking support portion by clamping. The housing has an annular top wall 101, a first cover wall 102 and a second cover wall 103. A groove structure is formed by the top wall 101, the first cover wall 102 and the second cover wall 103, so that it can be tightly covered with the skeleton 2. The top wall 101 abuts against the top end of the wire-walking support portion, providing stable support for the entire housing. The gap design between the bottom end of the first cover wall 102 and the top end inside the skeleton 2 can not only avoid interference with the internal structure of the skeleton 2, but also play a lateral protection role for the wires to a certain extent. The clamping and fixing method of the second cover wall 103 to the outer end face of the wire-walking support portion facilitates the installation and disassembly of the housing, is convenient for equipment maintenance and repair, and also ensures the connection reliability between the housing and the skeleton 2 during normal operation.

[0058] In addition, a wire-passing platform 5 and a wire-walking port 105 are provided on the top wall 101. Three wire-passing ports 501 are provided on the wire-passing platform 5. The wire-walking ports 105 are annularly and evenly distributed on the top wall 101. A wire-bundling frame 4 is further provided on the top wall 101 near the wire-passing platform 5. By providing the wire-passing platform 5 and the multiple wire-passing ports 501, the three-phase wires of the coil winding can respectively enter the wire-passing platform 5 through the wire-walking ports 105 and be connected to the external wires through the wire-passing ports 501, thereby improving the neatness of the three-phase wires.

[0059] To achieve the connection between the housing and the wire routing support part, refer to Figure 5 and in combination with Figure 2 As shown, a clamping block 205 is provided on the outer end surface of any wire routing support part in each group. At the same time, a clamping groove 104 corresponding to the clamping block 205 is opened at the bottom of the second housing wall 103; the clamping block 205 on the outer end surface of the wire routing support part corresponds to the clamping groove 104 at the bottom of the second housing wall 103, achieving the precise positioning and rapid connection between the housing and the skeleton 2.

[0060] In summary, the straight-chain automatic wire-straightening housing structure of this embodiment includes a housing, a skeleton 2, and wire routing support parts provided on the skeleton 2. Among them, the housing covers one end of the chain-shaped skeleton 2 after curling. The housing is snap-fitted with the wire routing support parts. A wire routing groove 204 is provided on the outer wall of the wire routing support part along the circumferential direction. A wire guiding groove is opened axially on the wire routing support part. The wire routing groove 204 is communicated with the wire guiding groove. A wire-straightening part is provided on the housing. The wire-straightening part is used to press the wire tightly into the wire guiding groove along the radial direction. The provision of the wire routing groove 204 and the wire guiding groove on the wire routing support part realizes the arrangement and storage of the wire, enabling the wire to be distributed along the wire routing groove 204 and the wire guiding groove. As the wire-straightening part presses the wire tightly, the wire is closely attached to the wire routing groove 204 and the redundant part of the wire is stored in the wire guiding groove, forming an effect of automatic wire arrangement, and effectively avoiding the situations such as shaking and displacement of the wire during the operation of the equipment, improving the stability of the wire arrangement, and ensuring the normal operation of the equipment.
