Description

TECHNICAL FIELD

[0001] The utility model relates to the packaging technical field, especially a motor packaging structure. BACKGROUND

[0002] In prior art, when the stator and rotor of the motor are packaged, the packaging material is usually completely covered on the surface of the stator or rotor, so that the stator or rotor is in direct contact with the packaging material around. Since the stator core and rotor core are both composed of multiple layers of silicon steel sheets, the silicon steel sheets on the end faces of the stator core and rotor core are the most fragile parts. The packaged stator core and rotor core are prone to relative movement with the packaging material during transportation and taking, and the silicon steel sheets at the position without welding seam are extremely prone to edge lifting when subjected to axial force, resulting in abnormal product quality, and even causing the shutdown of the entire production line.

[0003] In addition, since the thickness of the end position of the stator core or rotor core is 0.2mm-0.35mm (equivalent to the thickness of the blade), and the edge of the stator core or rotor core is relatively sharp. When the edge of the stator core or rotor core contacts the packaging material, it is extremely easy to shear the packaging material, and at the same time, due to the bumping, the packaging material is repeatedly sheared, causing the packaging material to produce debris and causing the cleanliness of the stator core or rotor core to be abnormal. At the same time, since the rotor core relies on the balance disc for force in the packaging material, it is prone to rotation under the excitation of vibration during transportation, and the silicon steel sheet will cut the packaging material when the rotor core rotates, causing the packaging material to produce abrasive dust and damage the side wall of the rotor core.

[0004] In prior art, the structure of the stator core and rotor core is variable, specifically the core thickness, diameter, installation quantity and installation position of the stator core or rotor core in the packaging structure are all different. When designing the product packaging structure, a special packaging needs to be developed for different products, which has high development cost and long development cycle. UTILITY MODEL CONTENT

[0043] The packaging structure provided by the present application will be described in detail below in combination with the drawings and preferred embodiments.

[0044] The present application provides a motor packaging structure, which is used for packaging predetermined components to facilitate storage and transportation.

[0045] As shown in Figures 1-4 , and in combination with Figure 7 , the packaging structure preferably comprises a support assembly 1, a containing assembly 2 and a shell, the shell has a containing space 3, and the support assembly 1 and the containing assembly 2 are both placed in the containing space 3. The number of the support assembly 1 is at least one set, and the support assembly 1 comprises a mounting disc, at least one receiving cavity is provided on the mounting disc, preferably a plurality of receiving cavities are provided, and the containing assembly 2 is used for being placed in a corresponding receiving cavity. The containing assembly 2 is used for supporting and limiting the predetermined components 4, so that the edges of the predetermined components 4 are suspended.

[0046] The present application provides a packaging structure, which can accommodate a plurality of predetermined components 4 through the mounting disc of the support assembly 1, so as to realize the overall packaging of the plurality of predetermined components 4 and improve the packaging efficiency. At the same time, the packaging structure can use the containing assembly 2 to limit and support the predetermined components 4 when the predetermined components 4 are packaged, so that the edges of the predetermined components 4 are suspended, the edges of the predetermined components 4 are prevented from contacting the packaging material during transportation and rubbing with the packaging material to cause edge lifting or abrasion, and the transportation protection of the predetermined components 4 is realized, thereby effectively improving the protection capability of the packaging structure for the predetermined components 4.

[0047] In addition, the packaging structure can realize platformized packaging design, and in actual design, the packaging structure can be applied to the packaging design of different predetermined components 4 by simply adjusting the structure of the containing assembly 2, thereby greatly reducing the packaging cost and improving the development speed of the packaging structure.

[0048] In an embodiment, the mounting disc 11 is provided as a blister disc, and a plurality of receiving cavities are provided on the blister disc, so that the blister disc can accommodate a plurality of predetermined components 4 through the plurality of receiving cavities. For example, 6-12 receiving cavities can be provided on the blister disc to increase the carrying capacity of the blister disc.

[0049] Referring to Figures 7-9 , the shell comprises a top plate 5, a tray 6 and a surrounding plate 7, and the surrounding plate 7, the tray 6 and the top plate 5 jointly form the containing space 3.

[0050] In actual installation, the bottommost support assembly 1 can be fixed on the tray 6 first, then the predetermined component 4 is placed in the containing assembly 2, and the containing assembly 2 is placed in the corresponding receiving cavity of the mounting disc. Subsequently, the surrounding plate 7 is installed on the four peripheral edges of the tray 6, and the top plate 5 is installed on the surrounding plate 7, thereby completing the entire packaging process of the predetermined component 4.

[0051] It should be noted that the installation process of the predetermined component 4 can not be limited to the above steps, and the operator can change the order of the above installation steps as needed.

[0052] Referring to Figure 5 and Figure 14 In a preferred embodiment, the support assembly 1 further comprises a partition plate for covering the surface of the predetermined component 4 after the predetermined component 4 is placed in the receiving cavity. In this way, on the one hand, the upper part of the predetermined component 4 can be protected; on the other hand, the partition plate can also limit the axial position of the predetermined component 4 under the limitation of the top plate 5, preventing the predetermined component 4 from being damaged due to violent shaking in the axial direction during transportation.

[0053] Preferably, the number of support assemblies 1 can be set to multiple, and all the support assemblies 1 are used to be stacked in sequence in the vertical direction and placed in the containing space 3. Specifically, after the containing assembly 2 and the predetermined component 4 are placed in the support assembly 1, a partition plate is placed above the support assembly 1. Then another set of support assemblies 1 is placed above the partition plate, and so on, until all the support assemblies 1 are stacked in sequence in the vertical direction.

[0054] <Embodiment 1>

[0055] Referring to Figure 6 In this embodiment, the predetermined component 4 comprises a stator core 41, and part of the stator core 41 protrudes outward to form a plurality of first protruding structures 411 arranged at intervals in the circumferential direction of the stator core 41, that is, the stator core 41 is arranged with arc-shaped first protruding structures 411 at intervals on the side wall thereof.

[0056] Referring to Figure 1 and Figure 2 The support assembly 1 comprises a first mounting disc 11, and at least one first receiving cavity 12 is arranged on the first mounting disc 11, and preferably a plurality of first receiving cavities 12 are arranged. The containing assembly 2 is used to be placed in a corresponding one of the first receiving cavities 12.

[0057] Referring to Figure 3 and Figure 4As shown, the accommodating assembly 2 comprises a first base 21 and a plurality of limiting blocks 22. The first base 21 is annular in shape. The limiting blocks 22 are fixed at predetermined positions 211 on the first base 21, preferably at the edges of the first base 21. The number of limiting blocks 22 matches the number of first protruding structures 411. The limiting blocks 22 are sequentially and evenly arranged along the circumference of the first base 21. The limiting blocks 22 are used to support and limit the first protruding structures 411 at positions other than the edges of the first protruding structures 411, so as to suspend the edges of the stator core 41, thereby avoiding the risk of the edges of the stator core 41 being rubbed by the packaging material during transportation, and thus achieving protection of the stator core 41 during transportation.

[0058] During actual installation, the first protruding structures 411 of the stator core 41 can be placed on the corresponding limiting blocks 22 to avoid contact between the stator core 41 and the first base 21.

[0059] In other embodiments, the limiting blocks 22 can also be fixed at positions other than the predetermined positions 211 on the first base 21 to support parts of the stator core 41 other than the first protruding structures 411, thereby achieving support of the entire stator core 41.

[0060] Referring to Figure 3 and Figure 4 As a specific example, the number of limiting blocks 22 is four, and the limiting blocks 22 are evenly distributed along the circumference of the first base 21, so that the four limiting blocks 22 can firmly support the stator core 41. In other specific examples, the number of limiting blocks 22 can also be set to three, five, or more as needed.

[0061] Continuing to refer to Figure 4 In an illustrative embodiment, the limiting blocks 22 are provided with accommodating grooves 221 matching the shapes of the first protruding structures 411, and the accommodating grooves 221 are used to accommodate and limit the corresponding first protruding structures 411.

[0062] Referring to Figure 4As shown, the bottom wall of the accommodating groove 221 is provided with a first gasket 222, which is used to support the first protruding structure 411 at a position other than the edge of the first protruding structure 411. The opposite side walls of the accommodating groove 221 are each provided with a second gasket 223, which is used to contact the side wall of the first protruding structure 411. In this way, the first protruding structure 411 of the stator core 41 can be placed in the accommodating groove 221, and the edges of the first protruding structure 411 are suspended by the first gasket 222 and the second gasket 223, so as to avoid the edges of the stator core 41 from contacting the packaging material and causing the edges of the stator core 41 to be warped and abraded.

[0063] Specifically, the provision of the second gasket 223 can prevent the first protruding structure 411 from contacting the side wall of the accommodating groove 221 and causing friction and damage to the stator core 41, and can also limit the circumferential position of the stator core 41 to avoid the stator core 41 from rotating during transportation.

[0064] As a specific solution, the opposite side walls of the accommodating groove 221 are each provided with a second gasket 223, and the second gasket 223 is provided in a structure in which the middle portion protrudes and the edges gradually transition to the side wall of the accommodating groove 221, so as to further prevent the second gasket 223 from contacting the edges of the first protruding structure 411 of the stator core 41.

[0065] In order to enable the limiting block 22 to firmly limit the stator core 41, the height of the accommodating groove 221 in the axial direction of the first base 21 is preferably greater than 10 mm. In order to better prevent the limiting block 22 from contacting the end surface of the stator core 41, the distance between the side wall of the accommodating groove 221 and the side wall of the first protruding structure 411 can be not less than 2 mm in actual design, and the distance between the bottom wall of the accommodating groove 221 and the bottom wall of the first protruding structure 411 can be not less than 6 mm. In order to prevent the stator core 41 from contacting the first mounting disc 11, the distance between the inner wall of the first mounting disc 11 and the outer wall of the stator core 41 can be not less than 10 mm in actual design.

[0066] Referring to Figure 5 As shown, the support assembly 1 further includes a first partition plate 13, and the first partition plate 13 is fixed with first protrusions 131 arranged at intervals. The first partition plate 13 is used to cover the surface of the predetermined component 4 after the predetermined component 4 is placed in the first accommodating cavity 12, and the first protrusions 131 are extended into the first accommodating cavity 12. In this way, on the one hand, the upper portion of the stator core 41 can be protected, and on the other hand, the first protrusions 131 can also axially limit the stator core 41 in the first accommodating cavity 12, further protecting the stator core 41.

[0067] <Embodiment 2>

[0068] Referring to Figure 15As shown, in the present embodiment, the predetermined component 4 comprises a rotor core 42, and the rotor core 42 is provided with a balance disc 43 at an end thereof.

[0069] Referring to Figure 10 and Figure 11 As shown, the support assembly 1 comprises a second mounting disc 14, and the second mounting disc 14 is provided with at least one second receiving cavity 15, preferably a plurality of second receiving cavities 14. The containing assembly 2 is used to be placed in a corresponding one of the second receiving cavities 15.

[0070] Referring to Figure 12 and Figure 13 As shown, in the present embodiment, the containing assembly 2 comprises a second base 23 and a positioning member 241 fixed on the second base 23. The positioning member 241 encloses a limiting cavity 242, and the limiting cavity 242 is shaped to match the balance disc 43, which is used to be placed in the limiting cavity 242 and to be in contact with the second base 23, so that the edge of the rotor core 42 is suspended. By avoiding the end face of the rotor core 42 in the design, the end face of the rotor core 42 can be prevented from contacting the packaging material during transportation, and the occurrence of edge lifting or chipping of the end face of the rotor core 42 can be avoided, and the rotor core 42 can be prevented from being damaged during transportation.

[0071] In the prior art, since the rotor core 42 needs to rely on the balance disc 43 to bear force in the packaging structure, the rotor core 42 and the balance disc 43 will rotate under the excitation of vibration, and the silicon steel sheet will cut the inner liner of the package to produce chipping and scratch the side wall of the rotor core 42 when the rotor core 42 rotates.

[0072] Referring to Figure 12 As an illustrative embodiment, the positioning member 241 is arc-shaped, and a plurality of positioning members 241 are arranged at intervals in the circumferential direction of the second base 23, and all the positioning members 241 enclose the limiting cavity 242.

[0073] Further, the balance disc 43 comprises a circular main body portion 431 (see Figure 15 ), and a part of the main body portion 431 protrudes outward to form a plurality of second protruding structures 432 arranged at intervals in the circumferential direction of the main body portion 431.

[0074] Referring to Figure 12 The gap 243 between adjacent positioning members 241 is used to accommodate the second protruding structure 432 to prevent the balance disc 43 from rotating relative to the second base 23. In this way, the positioning member 241 can prevent the movement and rotation of the balance disc 43 at the same time, and avoid the rotor core 42 from moving to produce chipping and damage the side wall during transportation.

[0075] Referring to Figure 15As shown, in some embodiments, a cover plate 44 is arranged between the rotor core 42 and the balance disc 43, i.e. the balance disc 43 is fixed on one side of the cover plate 44, the rotor core 42 is fixed on the other side of the cover plate 44, the outer diameter of the cover plate 44 is greater than the outer diameter of the balance disc 43 and less than the outer diameter of the rotor core 42.

[0076] Preferably, the accommodating assembly 2 further comprises a stopper 244 (see Figure 12 and Figure 13 ), which is fixed on the second base 23 and located in the outer region of the positioning member 241, and the height of the stopper 244 in the axial direction of the second base 23 is greater than the height of the positioning member 241 in the axial direction of the second base 23. The stopper 244 is used to contact the cover plate 44 after the cover plate 44 is tilted, so as to limit the tilt angle of the cover plate 44 relative to the second base 23.

[0077] Specifically, the stopper 244 is arranged in the outer region of the positioning member 241, and the fixed position of the stopper 244 on the second base 23 corresponds to the position of the cover plate 44 after installation. After the balance disc 43 is placed in the limiting cavity 242, the cover plate 44 is located above the stopper 244, and the stopper 244 is spaced apart from the cover plate 44 by a small distance. When the rotor core 42 is tilted, the cover plate 44 will also be tilted, and when the tilt angle of the cover plate 44 reaches a certain value, the cover plate 44 can contact the stopper 244 and stop rotating under the limitation of the stopper 244.

[0078] It should be noted that the shape of the stopper 244 is not limited in the present application, and the shape of the stopper 244 can be designed arbitrarily as needed, as long as it can limit the cover plate 44 when the rotor core 42 is tilted.

[0079] Referring to Figure 12 and Figure 13 , in a specific example, the number of stoppers 244 is multiple, and the stoppers 244 are arranged in the outer region of the positioning member 241 and spaced apart along the circumference of the second base 23. The stoppers 244 can be connected or not connected with the positioning member 241.

[0080] Further preferably, the second base 23 is annular, and the outer diameter of the second base 23 is greater than the outer diameter of the rotor core 42. The upper portion of at least part of the edge of the second base 23 is provided with a baffle plate 231 (see Figure 13 ), at this time, the shape of the baffle plate 231 is a cylindrical side wall or a part of a cylindrical side wall. The balance disc 43 and at least part of the rotor core 42 are accommodated in the mounting space 232 formed by the second base 23 and the baffle plate 231. The baffle plate 231 is used to limit the tilt angle of the rotor core 42.

[0081] Specifically, the baffle 231 is used to contact the rotor core 42 when the rotor core 42 is tilted, preventing the side wall of the rotor core 42 from directly contacting the second mounting disc 14 and causing damage. For example, if the balance disc 43 is disengaged from the limiting cavity 242, the baffle 231 can contact the rotor core 42 after the rotor core 42 is tilted, so as to further block the rotation of the rotor core 42.

[0082] Referring to Figure 12 and Figure 13 , in a preferred case, the number of baffles 231 is two, and the two baffles 231 are spaced and oppositely arranged in the circumferential direction of the second base 23. An operation cavity 232 is arranged between the two baffles 231 in the circumferential direction of the second base 23. That is, the two sides of each baffle 231 are provided with an operation cavity 232, and the operator can manually or automatically install or remove the rotor core 42 through the containing groove 232.

[0083] As shown in Figure 15 , further, the cover plate 44 is provided with a plurality of reinforcing ribs 441 protruding towards the side of the balance disc 43, all of which extend in the radial direction of the cover plate 44 and are spaced apart on the outer side of the balance disc 43 in the circumferential direction of the cover plate 44. When the balance disc 43 is placed in the limiting cavity 242, the reinforcing ribs 441 are spaced apart from the positioning member 241 in the axial direction of the second base 23.

[0084] Referring to Figure 12 , Figure 13 and Figure 15 , in a specific example, the number of stop members 244 is multiple pairs, and each pair of stop members 244 forms a limiting groove 245 for containing the reinforcing rib 441, which can circumferentially limit the reinforcing rib 441 to further prevent the rotor core 42 from rotating relative to the second base 23.

[0085] Referring to Figure 14 , the support assembly 1 further comprises a second partition plate 16, and the second partition plate 16 is fixed with a plurality of second protrusions 161 spaced apart. The second partition plate 16 is used to cover the surface of the predetermined component 4 after the predetermined component 4 is placed in the second containing cavity 15, and the second protrusions 161 are extended into the second containing cavity 15. In this way, on the one hand, the upper part of the rotor core 42 can be protected; on the other hand, the second protrusions 161 can also axially limit the rotor core 42 in the second containing cavity 15, further protecting the rotor core 42.

[0086] In summary, the utility model provides a motor packaging structure, this packaging structure can contain multiple predetermined components 4 through the mounting disc of support assembly 1, to realize the overall packaging of multiple predetermined components 4, improve packaging efficiency. Meanwhile, the packaging structure can use containing assembly 2 to limit and support predetermined components 4 when packaging, make the edge of predetermined components 4 hang in the air, avoid the edge of predetermined components 4 contact packing material in transportation, and with packing material friction and occur edge warping or grinding scrap, further realize the transportation protection of predetermined components 4, effectively improve the protection ability of packaging structure to predetermined components 4.
