[0001] This utility model relates to a compressor system, and more particularly to a vehicle-mounted compressor. Background Technology

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

[0003] The increasing market competition in the automotive electric compressor market has driven down motor prices, placing higher demands on cost control. Due to cost constraints, in existing automotive compressors, the copper wires on the outer side of the upper frame are located at the intake port during stator and housing installation. During compressor operation, these copper wires are subjected to refrigerant impact, easily causing damage. Furthermore, after assembly, the copper wires on the outer side of the upper frame are too close to the inner wall of the housing. When adding frame protection measures, space constraints cause interference between the protective cover and the housing, affecting service life.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle compressor that extends its service life by installing the junction box on one side of the lower frame of the stator, so that the copper wire outlet avoids the air intake.

[0006] To achieve the above objectives, this utility model discloses a vehicle-mounted compressor, which includes:

[0007] The stator has an upper frame and a lower frame arranged opposite to each other, and the outer wall of the upper frame has a winding post for winding copper wire.

[0008] A housing for mounting the stator, the housing having a first end and a second end disposed opposite to each other, and an air intake port being provided at the second end of the housing;

[0009] A junction box is installed on one side of the lower frame of the stator, and the end of the copper wire is led out from one side of the lower frame of the stator and converges at the junction box;

[0010] The stator is installed in the housing, and the upper frame side of the stator corresponds to the first end of the housing, the lower frame side of the stator corresponds to the second end of the housing, and the junction box is positioned to avoid the air intake at the second end of the housing.

[0011] As a further description of the above technical solution, the number of copper wires converging from the junction box is set to three groups.

[0012] As a further description of the above technical solution, the junction box is configured as a plurality of staggered rectangular blocks that match the number of copper wire groups gathered.

[0013] As a further description of the above technical solution, at least a portion of the copper wires that converge from the junction box are coiled around the inner side of the lower stator frame.

[0014] As a further description of the above technical solution, the copper wires converging from the junction box are covered with a sheath material.

[0015] As a further description of the above technical solution, the stator has a body between the upper and lower frames of the stator, and the diameter of the body is larger than the diameter of the lower frame.

[0016] As a further description of the above technical solution, the diameter of the stator body is at least 4 mm larger than the lower frame of the stator.

[0017] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0018] This utility model of a vehicle compressor allows for the installation of a junction box on one side of the lower frame of the stator, with the copper wire outlet side also located on the lower frame side. After the stator is installed into the housing, the junction box is positioned to avoid the intake port.

[0028] Please see Figure 1-3 This embodiment provides a vehicle-mounted compressor, which includes:

[0029] Stator 1 has an upper frame 11 and a lower frame 12 arranged opposite to each other. The outer wall of the upper frame 11 has a winding post 111 for winding copper wire 4.

[0030] Housing 2, housing 2 is used for mounting stator 1, housing 2 has a first end and a second end that are arranged opposite to each other, and an air intake 21 is provided at the second end of housing 2;

[0031] Junction box 3 is installed on one side of the lower frame 12 of stator 1. The end of copper wire 4 is led out from one side of the lower frame 12 of stator 1 and converges to junction box 3.

[0032] The stator 1 is installed in the housing 2, and the upper frame 11 of the stator 1 corresponds to the first end of the housing 2, the lower frame 12 of the stator 1 corresponds to the second end of the housing 2, and the junction box 3 is positioned to avoid the air intake 21 at the second end of the housing 2.

[0033] For the above structure, during installation, the operator only needs to first wind most of the copper wire 4 around the stator core inside the stator 1, and then install the junction box 3 on one side of the lower frame 12 of the stator 1. This allows the lead-out end of the copper wire 4 to be led out from one side of the lower frame 12 of the stator 1, pass through the junction box 3, converge and coil to the top and inner area of ​​the lower frame 12, and then be electrically connected to the corresponding node. It is worth noting that in this embodiment, the lower frame 12 of the stator 1 is installed at the second end of the housing 2 with the air intake 21, and the junction box 3 installed on one side of the lower frame 12 avoids the position of the air intake 21.

[0034] With the structure of the above embodiment, since one side of the lower frame 12 of the stator 1 is installed into the housing 2, the position of the lower frame 12 of the stator 1 corresponds to the position of the second end of the housing 2 with the air intake 21. Therefore, the air intake 21 avoids one end of the original upper frame 11 of the stator 1. According to the general structure, one side of the upper frame 11 of the stator 1 is installed into the housing 2, so that the position of the upper frame 11 of the stator 1 corresponds to the position of the second end of the housing 2 with the air intake 21. One end of the upper frame 11 has an externally provided winding post 111, and the copper wire 4 is wound on the externally provided winding post 111. In the comparative example, the copper wire 4 outside the winding post 111 may touch the air intake 21, thus affecting the exposed copper wire inside due to the refrigerant entering and exiting the air intake 21. However, in this embodiment, the original exposed copper wire 4 avoids the open air intake 21 at the second end of the housing 2 by reversing the installation method. The copper wire 4 bundle is located in the area of ​​the top of the lower frame 12 relative to the inner perimeter and generally has insulation after passing through the junction box 3, which effectively avoids damage to the copper wire 4 and avoids the reduction in strength of the copper wire 4 caused by the impact of refrigerant. The entire motor has a longer service life.

[0035] Furthermore, the number of copper wires 4 converging at the junction box 3 is set to three groups. In the existing comparative examples, the copper wires 4 directly led out from one side of the upper frame 11 of the stator 1 are generally six groups, while in this embodiment, the copper wires 4 that are installed at one end of the lower frame 12 and connected to the junction box 3 are converged into three groups. The purpose of this is to minimize the impact of external forces on the wire harness, especially the impact from the air intake 21 at the second end of the housing 2.

[0036] Furthermore, such as Figure 3 As shown, the junction box 3 is configured as multiple staggered rectangular blocks that match the number of copper wires 4 gathered together. Specifically, in this embodiment, the number of copper wires 4 gathered in the junction box 3 is three. Therefore, the junction box 3 in this embodiment is configured as three staggered rectangular blocks, each block corresponding to one set of copper wires 4. The convergence direction of the three sets of copper wires 4 is consistent, all on the same side of the junction box 3, along the top edge of the lower frame 12 of the stator 1, and coiled around the axial direction until connected to the corresponding node. This ensures that the three sets of copper wires 4 are arranged in parallel and minimizes interference with the housing 2, etc.

[0037] Furthermore, at least a portion of the copper wires 4 that converge at the junction box 3 are coiled inside the lower frame 12 of the stator 1. Specifically, the portion of the copper wires 4 that converge at the junction box 3 is positioned as close as possible to the axial direction and as far away as possible from the inner wall of the housing 2, so as to minimize the interference of external components such as the housing 2 on the copper wires 4.

[0038] Furthermore, the copper wires 4 converging at junction box 3 are covered with a sheath material. This structure prevents the copper wires 4 near the air intake 21 on the housing 2 from affecting their lifespan by passing through the air intake 21 in the environment.

[0039] Furthermore, the lower frame 12 of the stator 1 does not interfere with the housing 2. Specifically, the stator 1 has a body between the upper frame 11 and the lower frame 12, and the diameter of the body is larger than the diameter of the lower frame 12. The diameter of the stator 1 body is at least 4 mm larger than the lower frame 12. Through the above structure, by means of the axial inward contraction of the lower frame 12, interference with the housing 2 due to the possible outward expansion of the copper wire 4 on one side of the lower frame 12 is avoided as much as possible, thus avoiding any impact on the lifespan of the copper wire 4.

[0040] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.
