Technical Field

The invention relates to a compressor device, in particular to a new energy source vertical rotary compressor device for an electric vehicle.

Background

The market scale of electric vehicles is expanding rapidly, and since the space of a power room of an electric vehicle is limited, a compressor device that is generally used in a vehicle can be fixed in the power room only using a horizontal compressor at present. However, the application speed of the known horizontal rotary compressor must be higher than 2000 rpm, and the inclination angle of the vehicle must be less than 15 degrees, so that the characteristics of the known horizontal rotary compressor greatly limit the possibility of the application in the electric vehicle for the optimum application range of the new energy compressor which can be used in the electric vehicle, i.e. the speed is lower than 900 rpm, and the inclination angle is within 30 degrees.

On the other hand, although the known vertical rotary compressor has no limitation on the operating speed and the inclination angle of the vehicle, because the compressor is vertical, the compressor is difficult to be placed in the power room space of the electric vehicle (for example, the total height of the compressor is required to be lower than 170 mm).

Detailed Description

Certain terms are used throughout the description and following claims to refer to particular components. As one of ordinary skill in the art will appreciate, manufacturers may refer to a component by different names. The present specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. Furthermore, the term "coupled" as used herein includes any direct and indirect structural coupling. Thus, if a first device couples to a second device, that connection may be through a direct structural connection or through an indirect structural connection via other devices and connections.

Please refer to fig. 1. Fig. 1 is a schematic sectional view of an embodiment of a vertical rotary compressor apparatus according to the present invention. In the embodiment of the present invention, the vertical rotary compressor device 1 is a new energy compressor device, which can be used in pure electric or hybrid electric vehicles, but not limited to this, and as a result of the optimization of the device height, the compressor device of the present invention can also be applied to other air conditioning occasions in the market, especially to a device which needs to utilize the rotation speed and the inclination angle characteristics of the vertical compressor and is required to be used in a limited small space. The stand-up rotary compressor arrangement 1 comprises a compressor housing 2, a compressor pump 6 and an electric motor 7. The compressor shell 2 is made of aluminum alloy, the aluminum alloy is convenient for casting and molding on the premise of meeting the strength, the compressor shell 2 adopts a semi-closed structure, namely comprises an upper end cover 21, a lower end cover 22 and a hollow non-circular shell 23, and the upper end cover 21 and the lower end cover 22 are detachably combined at the upper end and the lower end of the shell 23 to form the semi-closed compressor structure.

The compression pump 6 and the motor 7 are respectively disposed in the compressor housing 2, and more specifically, in the upright rotary compressor device 1, the compression pump 6 is located at the lower half portion in the direction of gravity in the casing 23, and the motor 7 is connected to the compression pump 6 and located at the upper half portion in the direction of gravity in the casing 23. As shown in the drawings, since the compressor housing 2 is cast from an aluminum alloy, the plasticity in the shape profile is considerably high, the suction pipe 3, the discharge pipe 4 and the electric joint 5 of the upright rotary compressor arrangement 1 are therefore all arranged on the housing 23, wherein the suction pipe 3 for fluid flowing into the vertical rotary compressor device 1 is located at the position corresponding to the compression pump 6 on the housing 23, the discharge pipe 4 for fluid flowing out of the vertical rotary compressor device 1 is located at the position corresponding to the motor 7 on the housing 23, the fluid (refrigerant) for heat exchange enters the vertical rotary compressor device 1 from the suction pipe 3, is compressed to high temperature and high pressure by the compression pump 6, then flows through the motor 7, and finally leaves the vertical rotary compressor device 1 from the discharge pipe 4, at the same time, the lubricating oil in the vertical rotary compressor device 1 lubricates the rotating shafts of the compression pump 6 and the motor 7 as the fluid flows in the vertical rotary compressor device 1.

In addition to the suction pipe 3 and the discharge pipe 4 being arranged on the housing 23 (or called side arrangement), the electric connector 5 for supplying the electric power to the electric motor 7 is also arranged on the housing 23, which is also located at the upper half of the vertical rotary compressor device 1 corresponding to the electric motor 7, so as to accomplish the purpose of side air intake, exhaust and electric connector.

The upright rotary compressor device 1 in the embodiment of the present invention further optimizes the internal configuration of the compressor device after the suction pipe 3, the discharge pipe 4, and the electric joint 5 are all moved to the side. That is, the height h1 of the core 71 of the motor 7 is greater than 0.13 times the core outer diameter d1 and less than 0.4 times the core outer diameter d 1. In addition, because of the double-cylinder power balance, the height of the upper bearing can be reduced, so that the distance h2 between the upper end of the iron core 71 of the motor 7 and the upper end cover 21 is between 8 and 40 mm (while the oil circulation rate is maintained below 2%), the distance h3 between the lower end of the eccentric shaft 61 of the compression pump 6 and the lower end cover 22 is between 1 and 10 mm, the cushion pad and the foot stand at the bottom of the lower end cover 22 are removed, and the side is fixed in the power chamber of the electric vehicle (the side fixing part is not shown).

With the above arrangement, the total height H (distance from the top of the upper end cover 21 to the bottom of the lower end cover 22) of the upright rotary compressor assembly 1 can be less than or equal to 215 mm, preferably can be reduced to 170 mm, and the total width D can be between 100-300 mm. In addition, the ratio of the total height H to the stator outer diameter d2 of the motor 7 is preferably between 1.0 and 2.0, so that the air displacement can be designed to be 20

c.c./r to 80 c.c./r.

In the vertical rotary compressor device disclosed in the embodiment of the present invention, an aluminum alloy material is used as a semi-closed casing of the compressor, and the suction pipe, the discharge pipe and the electric connector are moved from the upper end cover and the lower end cover of the semi-closed casing to the lateral casing, and further, the sizes of the compression pump and the electric motor are optimized, unnecessary external parts are eliminated, so that the height of the compressor is reduced to an appropriate height, and the compressor can be placed in the limited power room space of the electric vehicle.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
