Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a stator wire skeleton of a vehicle-mounted electric scroll compressor. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] With the rapid development of the new energy vehicle market, demand for automotive electric scroll compressors has also increased, placing higher demands on their quality. Currently, there are two methods for mounting and securing the stator of automotive electric scroll compressor motors: shrink fit and locking bolts. Shrink fit creates an interference fit between the aluminum shell and the stator core. The aluminum shell is heated to enlarge the inner hole, allowing the stator to fit inside and then be tightly secured after cooling. Locking bolts, on the other hand, create a clearance fit between the aluminum shell and the stator core, securing the stator to the aluminum shell using tightening bolts.

[0004] In the process of fixing the aluminum shell and the stator core by locking bolts, the bolt holes for the stator locking bolts are very close to the outside of the existing frame. As a result, in the existing winding process, when winding in series, the coils in each phase are connected through the connecting wires on the outside of the frame. If there are bolt holes next to the stator wires, when the bolts are tightened, the heads of the bolts will scratch the stator wires, causing the stator to be scrapped.

[0005] Of course, to avoid the aforementioned abrasions, parallel winding can also be used. However, this method requires a lot of manual labor, significantly impacting production efficiency. Furthermore, compared to the series winding method, parallel winding is less suitable for high-voltage motor winding, making it difficult for automotive electric scroll compressors to meet the higher battery voltage requirements. This could potentially miss the market demand for faster charging and improved range in new energy vehicles.

[0006] Currently, there is no stator wire frame for an on-vehicle electric scroll compressor that can solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a stator wire frame for a vehicle-mounted electric scroll compressor, which can avoid the stator wire from being scratched when the winding is connected in series by using an avoidance mechanism.

[0008] In order to achieve the above-mentioned object, the present invention discloses the following vehicle-mounted electric scroll compressor stator wire frame, which is arranged on an iron core, and the iron core includes a plurality of bolts axially mounted on the iron core; wherein the vehicle-mounted electric scroll compressor stator wire frame includes:

[0009] A winding mechanism, wherein a plurality of the winding mechanisms are arranged around the axial direction, with a preset gap between each two winding mechanisms; the winding mechanism facing the axial direction is a first end, and the winding mechanism away from the axial direction is a second end;

[0010] a side wall mechanism, the side wall mechanism being arranged at the second end of a portion of the winding mechanism, and the side wall mechanism including a plurality of outwardly protruding protrusions on an outer wall away from the axial direction;

[0011] At least one avoidance mechanism, wherein any one of the avoidance mechanisms is provided corresponding to at least one of the bolts; any one of the avoidance mechanisms is provided at the second end of a portion of the winding mechanism, and the avoidance mechanism protrudes axially from the winding mechanism and the side wall mechanism, and any one of the avoidance mechanisms includes a baffle portion and an edge portion, the edge portion is provided on one side of the baffle portion, the edge portion is fixedly connected to the side wall mechanism, and the baffle portion is concave inwardly in the axial direction so that the baffle portion is used to avoid the bolt on the iron core corresponding to the avoidance mechanism;

[0012] Wherein, at least part of the side wall mechanism and the avoidance mechanism are connected together around the axial direction, so that all the side wall mechanism and the avoidance mechanism form a complete ring around the axial direction.

[0013] Furthermore, the side wall mechanism includes a plurality of rows of protrusions distributed along the axial direction on an outer wall away from the axial direction.

[0014] Furthermore, it also includes a winding baffle, which is arranged at the first end of the winding mechanism.

[0015] Furthermore, a total of nine winding mechanisms are included.

[0016] Furthermore, the nine winding mechanisms are arranged at equal angles around the axial direction.

[0017] Furthermore, one of the avoidance mechanisms includes two edge portions mirror-imaged along a center line of the baffle portion on both sides of the baffle portion.

[0018] Furthermore, the two edge portions protrude outward in a direction away from the axial direction, so that a portion of the bolt is enclosed by the avoidance mechanism.

[0019] Furthermore, the baffle portion and the edge portion are of an integrated structure.

[0020] Furthermore, the stator is arranged on a side of the avoidance mechanism close to the axial direction when the stator passes through the avoidance mechanism, and is arranged on a side of the sidewall mechanism away from the axial direction when the stator passes through the sidewall mechanism.

[0021] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0022] The stator wire frame of the vehicle-mounted electric scroll compressor of the present invention can be provided with a baffle portion that is concave inward in the axial direction on the avoidance mechanism, so that the avoidance mechanism avoids the bolt setting, and the stator wire can pass through the baffle portion toward one side of the axial direction, avoiding the problem of stator wire wear and scrapping caused by the bolt contacting the stator wire.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes the implementation of the present invention based on its overall structure.

[0029] See Figure 1-2 , is a stator wire frame of a vehicle-mounted electric scroll compressor of this embodiment, which is arranged on an iron core 100. The iron core 100 includes a plurality of bolts 101 axially mounted on the iron core 100; wherein the stator wire frame of the vehicle-mounted electric scroll compressor includes:

[0030] A winding mechanism 1, wherein multiple winding mechanisms 1 are arranged axially, with a preset gap between each two winding mechanisms 1; the winding mechanism 1 facing the axial direction is the first end, and the winding mechanism 1 away from the axial direction is the second end;

[0031] The side wall mechanism 2 is provided at the second end of the winding mechanism 1. The side wall mechanism 2 includes a plurality of outwardly protruding protrusions 21 on the outer wall away from the axial direction.

[0032] At least one avoidance mechanism 3, wherein any avoidance mechanism 3 is provided corresponding to at least one bolt 101; any avoidance mechanism 3 is provided at the second end of a portion of the winding mechanism 3, and the avoidance mechanism 3 protrudes axially from the winding mechanism 1 and the side wall mechanism 2, and any avoidance mechanism 3 includes a baffle portion 31 and an edge portion 32, the edge portion 32 is provided at one end of the baffle 31, the edge portion 32 is fixedly connected to the side wall mechanism 2, and the baffle portion 31 is axially concave so that the baffle portion 31 is used to avoid the bolt 101 corresponding to the avoidance mechanism 3;

[0033] At least part of the side wall mechanism 2 and the avoidance mechanism 3 are connected together in the axial direction, so that all the side wall mechanism 2 and the avoidance mechanism 3 form a complete ring in the axial direction.

[0034] Through the above structure, during the installation process, when the stator wire 200 is axially wound around the side wall mechanism 2 and the avoidance mechanism 3, when the stator wires 200 of the same row are wound onto the side wall mechanism 2, the stator wire 200 is wound and arranged adjacent to the outer wall of the side wall mechanism 2 away from the axial direction, and the same stator wire 200 is arranged on the same side of the raised portion 21 at the same axial height on the side wall mechanism 2, so as to limit the stator wire 200 in the axial direction through the raised portion 21. When the stator wire 200 is wound onto the avoidance mechanism 3, since the avoidance mechanism 3 protrudes axially from the winding mechanism 1 and the side wall mechanism 2, the stator wire 200 can bypass the axially protruding baffle portion 31 of the avoidance mechanism 3 toward the axial side. Since the bolt 101 is arranged on the side away from the axial direction of the avoidance mechanism 3, the stator wire 200 can avoid any possibility of contact with the bolt 101 on the side of the core 100 during winding.

[0035] At the same time, in this embodiment, when the stator wire 200 is wound, since the stator wire 200 avoids the position of the bolt 101 during the winding process by means of forward and reverse winding, this embodiment can adopt a series connection method for winding, thereby avoiding the additional labor consumption caused by the need to avoid the bolt 101 and adopt a parallel connection method for winding, and the negative impact of the parallel connection method itself on the performance of the compressor product. It can be used in new energy vehicle systems with higher battery voltages.

[0036] Specifically, in this embodiment, the combination of the plurality of side wall mechanisms 2 and the plurality of avoidance mechanisms 3 connected together around the axial direction is determined according to the number and positions of the actual bolts 101 .

[0037] Furthermore, if Figure 1 As shown, in this embodiment, the copper wire is wound around the position of the winding mechanism 1. Therefore, the height of the axial projection of the avoidance mechanism 3 is set to at least cover the entire thickness of the copper wire. At the same time, since the stator wire 200 is wound and attached to the axial side of the baffle portion 31, the height of the axial projection of the avoidance mechanism 3 can also at least cover and additionally protrude beyond a portion of the stator wire 200, so as to make the fixation of the stator wire 200 more stable. Specifically, a avoidance mechanism 3 includes two edges 32 mirrored along the center line of the baffle portion 31 on both sides of the baffle portion 31, and the two edges 32 protrude outward in a direction away from the axial direction so that part of the bolt 101 is enclosed by the avoidance mechanism 3. Therefore, with the protection of the additional protruding edge 32, the avoidance mechanism 3 also provides better protection for the stator wire 200 on the axial side.

[0038] Furthermore, the outer wall of the sidewall mechanism 2, facing away from the axial direction, includes multiple rows of raised portions 21 distributed along the axial direction. Specifically, in this embodiment, three turns of stator wires 200 are arranged in an array along the axial direction, and the outer side of the sidewall mechanism 2 includes three corresponding rows of raised portions 21. The provision of multiple rows of raised portions 21 facilitates the physical isolation and splitting of different turns of stator wires 200, achieving a better fixing effect and more convenient installation efficiency.

[0039] Furthermore, if Figure 1 As shown, it also includes a winding baffle 11, which is arranged at the first end of the winding mechanism 1. The winding baffle 11 serves to limit and protect the copper wire wound on the winding mechanism 1, and has a similar function to the side wall mechanism 2 or the avoidance mechanism 3 at the second end of the winding mechanism 1.

[0040] Furthermore, in this embodiment, a total of nine winding mechanisms 1 are included, that is, the stator in this embodiment is a nine-slot six-pole structure arrangement in which nine winding mechanisms 1 are arranged at equal angles around the axial direction and wound in series.

[0041] Furthermore, in the avoidance mechanism 3, the baffle portion 31 and the edge portion 32 are integrally constructed. Figure 2 As shown, the winding mechanism 1, the side wall mechanism 2 and the avoidance mechanism 3 are of an integrated structure to meet the structural strength requirements for supporting the stator wire 200 and are easy to prepare.

[0042] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Some industry standards or slightly modified implementations based on customized methods or implementations described in the embodiments can also achieve the same, equivalent, or similar implementation effects as the above embodiments, or predictable implementation effects after modification. Examples that apply these modified or modified data acquisition, processing, output, judgment methods, etc. can still fall within the scope of optional implementation schemes of this application.

[0043] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
