Description

Electric compressor installation structure with dustproof mount

[0001] The present invention relates to an electric compressor installation structure having a vibration damping mount, and more specifically, to an electric compressor installation structure in which a first vibration damping mount disposed on one side of the electric compressor and a second vibration damping mount disposed on the other side are asymmetrical or have different elastic moduli to achieve a state of equilibrium by considering the elastic moduli of the suction pipe and the discharge pipe.

[0002] Generally, automobiles are equipped with an air conditioning system for heating and cooling the interior. This system maintains the interior temperature at an appropriate level regardless of external temperature fluctuations, thereby ensuring a comfortable indoor environment.

[0003] An air conditioning system includes a compressor that compresses low-temperature, low-pressure gaseous refrigerant drawn in from an evaporator into high-temperature, high-pressure gaseous refrigerant and sends it to a condenser. Compressors applied to automobiles include mechanical compressors driven by engine power and electric compressors utilizing motors driven by electricity; recently, as the electrification of automobiles accelerates, the use of electric compressors is increasing.

[0004] Conventional compressors are mounted on the vehicle body frame via a separate mounting bracket inside the vehicle's engine compartment. However, in this case, the compressor may be damaged or broken by external vibrations transmitted directly to the frame during vehicle operation, and noise and vibration generated from the compressor during operation are transmitted directly to the vehicle body through the frame, resulting in reduced durability of the compressor and degraded NVH performance of the vehicle.

[0005] As a result, the compressor can be mounted to the vehicle frame through a vibration-damping mount containing elastic rubber, etc. However, in a vertical mount configuration where the vibration-damping mount is installed vertically, rolling mode resonance may occur because the moment generated relative to the compressor's rotation axis at a specific RPM and the elastic mode of the vibration-damping mount move identically. In other words, there is a problem where vibration is abnormally amplified at a specific RPM due to the superposition of the rolling mode movement and the elastic mode movement.

[0006] The purpose of the present invention is to provide an electric compressor installation structure in which a first anti-vibration mount disposed on one side of the electric compressor and a second anti-vibration mount disposed on the other side are asymmetrical or have different elastic moduli so as to achieve a state of equilibrium by considering the elastic moduli of the suction pipe and the discharge pipe.

[0007] The technical problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0008] An embodiment of the present invention for solving the above problem provides an electric compressor installation structure having a vibration-damping mount, comprising: a housing having an internal space such that a compression unit for compressing a refrigerant and a motor unit for driving the compression unit are disposed therein; a suction pipe installed in the housing for sucking a refrigerant into the interior of the housing; a discharge pipe installed in the housing for discharging a refrigerant from the interior of the housing; one or more first vibration-damping mounts installed on a first side relative to the central vertical plane of the housing and having elasticity to isolate vibrations; and one or more second vibration-damping mounts installed on a second side opposite to the first side and having elasticity to isolate vibrations; wherein the suction pipe or the discharge pipe is installed on the second side.

[0009] According to an embodiment, the first dustproof mount and the second dustproof mount may have asymmetrical installation heights.

[0010] According to an embodiment, the first dustproof mount and the second dustproof mount may have an asymmetrical installation angle with respect to the central vertical plane.

[0011] According to the embodiment, the elastic modulus of the first dustproof mount and the second dustproof mount may be different from each other.

[0012] According to an embodiment, the housing includes a plurality of protruding lugs formed to protrude from the outer surface, and the first dustproof mount and the second dustproof mount may each be provided on the plurality of protruding lugs.

[0013] According to an embodiment, the horizontal reaction force and the vertical reaction force of the elastic modulus of the suction pipe, the elastic modulus of the discharge pipe, the elastic modulus of the first anti-vibration mount, and the elastic modulus of the second anti-vibration mount can be offset from each other.

[0014] According to an embodiment, the position of the integrated pipe, which is an intermediate position in the circumferential direction of the housing between the suction pipe and the discharge pipe, and the second connection position, where the center extension line of the second dustproof mount meets the housing, may be symmetrical with respect to the center horizontal plane of the housing.

[0015] According to an embodiment, a first connection position where the center extension line of the first dust-proof mount meets the housing may be positioned lower than the position of the integrated pipe, which is the intermediate position in the circumferential direction of the housing between the suction pipe and the discharge pipe, and a second connection position where the center extension line of the second dust-proof mount meets the housing may be positioned lower than the first connection position.

[0016] According to an embodiment, the installation angle of the first anti-vibration mount with respect to the center vertical plane may be greater than the installation angle of the second anti-vibration mount with respect to the center vertical plane.

[0017] According to an embodiment, the installation angle of the second dustproof mount may be 0°.

[0018] According to an embodiment, the first dustproof mount and the second dustproof mount are arranged symmetrically with respect to the central vertical plane, and the elastic modulus of the first dustproof mount may be greater than the elastic modulus of the second dustproof mount.

[0019] According to an embodiment, the first dustproof mount and the second dustproof mount may each be positioned at an angle with respect to the central vertical plane.

[0020] According to an embodiment, a plurality of first dustproof mounts are spaced apart along the longitudinal direction of the housing on the first side, and a plurality of second dustproof mounts are spaced apart along the longitudinal direction of the housing on the second side, wherein the plurality of first dustproof mounts are arranged parallel to each other and the plurality of second dustproof mounts are arranged parallel to each other.

[0021] According to an embodiment, a pair of first dustproof mounts are spaced apart along the longitudinal direction of the housing on the first side, and a pair of second dustproof mounts are spaced apart along the longitudinal direction of the housing on the second side, wherein the pair of first dustproof mounts and the pair of second dustproof mounts may be installed at an angle such that they become closer to each other with respect to the longitudinal direction of the housing as they move upward in the direction of gravity.

[0022] According to an embodiment, a pair of first anti-vibration mounts are spaced apart along the longitudinal direction of the housing on the first side, and a pair of second anti-vibration mounts are spaced apart along the longitudinal direction of the housing on the second side, wherein the installation angles of the pair of first anti-vibration mounts with respect to the central vertical plane are different from each other, and the installation angles of the pair of second anti-vibration mounts with respect to the central vertical plane may be different from each other.

[0023] According to an embodiment, the pair of first dust-proof mounts includes a first-1 dust-proof mount that is closer to the suction pipe than the discharge pipe and a first-2 dust-proof mount that is closer to the discharge pipe than the suction pipe, and the pair of second dust-proof mounts includes a second-1 dust-proof mount that is closer to the suction pipe than the discharge pipe and a second-2 dust-proof mount that is closer to the discharge pipe than the suction pipe, and the horizontal reaction force and vertical reaction force of the elastic modulus of the suction pipe, the elastic modulus of the first-1 dust-proof mount and the elastic modulus of the second-1 dust-proof mount may cancel each other out, and the horizontal reaction force and vertical reaction force of the elastic modulus of the discharge pipe, the elastic modulus of the first-2 dust-proof mount and the elastic modulus of the second-2 dust-proof mount may cancel each other out.

[0024] According to the present invention, at least one of the first and second vibration isolation mounts is positioned at an angle with respect to the central vertical plane of the housing, thereby suppressing the rolling mode and resonance of the compressor. At this time, since the suction pipe and discharge pipe connected to the housing also have a certain portion of elastic modulus and can perform a vibration isolation function, the horizontal and vertical equilibrium of the compressor can be accurately achieved by considering the elastic modulus of the suction pipe and discharge pipe as well. As a result, the vibration isolation characteristics of the compressor can be enhanced.

[0025] In addition, if a pair of first vibration isolation mounts and a pair of second vibration isolation mounts are positioned so as to be tilted in opposite directions, the movement of the compressor's pitching mode can be restricted and canceled out. As a result, the compressor's pitching mode and resonance can also be suppressed.

[0026] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the configuration of the invention described in the detailed description of the invention or the claims.

[0042]

[0043] First, let us look at an electric compressor installation structure having a dustproof mount according to the first embodiment of the present invention with reference to FIGS. 1 to 5.

[0044] The electric compressor having a dustproof mount according to the present invention comprises a housing (100), a suction pipe (200), a discharge pipe (300), a first dustproof mount (400), and a second dustproof mount (500).

[0045] The housing (100) forms the overall exterior of the electric compressor and has an internal space for arranging the compression section and the motor section inside. In this embodiment, the housing (100) includes a motor housing (front housing, 120) and a compression housing (rear housing, 140).

[0046] The motor unit is provided within the motor housing (120) and provides power for the compressor unit to compress the refrigerant. The motor unit may include a rotor coupled to a rotating shaft that is rotatably installed at the center of the motor housing (120), although not illustrated, and a stator fixed to the motor housing (120) and positioned radially outside the rotor. Additionally, the stator may include a stator core and a coil wound around the stator core.

[0047] The compression unit compresses the refrigerant introduced into the housing (100). In this embodiment, the compression unit is provided within the compression housing (140) and may include a pivot scroll coupled to a rotating shaft via an eccentric bushing (not shown) and a fixed scroll forming a compression chamber where the refrigerant is compressed together with the pivot scroll. As the compression unit is connected to the motor unit via the rotating shaft in this manner, the rotational force generated by the motor unit can be transmitted to the pivot scroll of the compression unit by the rotating shaft. However, this is not limited to this, and it is understood that other types of compression units may be used.

[0048] In addition, on the side opposite the compression unit relative to the motor unit, an inverter unit may be arranged that is electrically connected to the motor unit and supplies power to the motor unit and controls its operation through power and control signals transmitted from the outside. Specifically, the stator forms an electromagnetic field by power supplied from the inverter unit, and as the rotor rotates due to the electromagnetic field formed by the stator, a rotational force is generated to drive the compression unit.

[0049] The suction pipe (200) is installed in the housing (100) to suck refrigerant into the interior of the housing (100). The suction pipe (200) is installed on the motor housing (120), so that low-pressure refrigerant can flow through the suction pipe (200) into the space inside the motor housing (120) where the motor part is located.

[0050] The discharge pipe (300) is installed in the housing (100) to discharge refrigerant from inside the housing (100). The discharge pipe (300) is installed on the compression housing (140) so that high-pressure refrigerant compressed in the compression chamber can be discharged to the outside of the housing (100) through the discharge pipe (300).

[0051] The suction pipe (200) and the discharge pipe (300) are generally installed at the top of the housing (100) so that oil inside the housing does not flow out. In this embodiment, both the suction pipe (200) and the discharge pipe (300) are positioned on the second side relative to the center vertical plane (VS) of the housing (100).

[0052] Specifically, the suction pipe (200) and the discharge pipe (300) may be installed on the suction port (102) and the discharge port (104) provided in the housing (100). The suction port (102) and the discharge port (104) may be formed of metal, just like the housing (100), and the suction pipe (200) and the discharge pipe (300) each have at least a portion having an elastic modulus. In the drawings of the present invention, only a portion of the suction pipe (200) and the discharge pipe (300) having an elastic modulus is shown.

[0053] In the following description, as illustrated in FIG. 5, the suction pipe (200) and the discharge pipe (300) are integrated into a single virtual integrated pipe. At this time, the position (Lp) of the integrated pipe can be set as an intermediate position in the circumferential direction of the housing (100) between the position (Lp1) of the suction pipe (200) and the position (Lp2) of the discharge pipe. In this embodiment, the position (Lp) of the integrated pipe is positioned on the second side. Additionally, the elastic modulus (Kp) of the integrated pipe can be set as the sum of the elastic modulus (Kp1) of the suction pipe (200) and the elastic modulus (Kp2) of the discharge pipe (300).

[0054] One or more first anti-vibration mounts (400) are installed on the first side relative to the center vertical plane (VS) of the housing (100), and one or more second anti-vibration mounts (500) are installed on the second side opposite to the first side relative to the center vertical plane (VS) of the housing (100). The first anti-vibration mount (400) and the second anti-vibration mount (500) are insulation rubbers (vibration-insulating rubbers) and each have a certain elasticity and serve to insulate vibrations. The first and second anti-vibration mounts (400, 500) are generally installed at the bottom of the housing (100) to mount the electric compressor to the frame of the vehicle body.

[0055] In this embodiment, the housing (100) includes a plurality of protruding lugs (106) formed to protrude from the outer surface, and accordingly, the first anti-vibration mount (400) and the second anti-vibration mount (500) are each provided on the plurality of protruding lugs (106). Although not illustrated in detail, the protruding lugs (106) and each anti-vibration mount (400, 500) can be installed adjacently and joined by bolts.

[0056] In this embodiment, the description is based on the assumption that a pair of first dustproof mounts (400) are spaced apart along the longitudinal direction of the housing (100) on the first side, and a pair of second dustproof mounts (500) are spaced apart along the longitudinal direction of the housing (100) on the second side.

[0057] Specifically, a pair of first dust-proof mounts (400) includes a first-1 dust-proof mount (400a) that is closer to the suction pipe (200) than to the discharge pipe (300), and a first-2 dust-proof mount (400b) that is closer to the discharge pipe (300) than to the suction pipe (200). That is, the first-1 dust-proof mount (400a) is placed on the motor housing (120), and the first-2 dust-proof mount (400b) is placed on the compression housing (140).

[0058] Additionally, a pair of second dust-proof mounts (500) includes a second-1 dust-proof mount (500a) that is closer to the suction pipe (200) than to the discharge pipe (300), and a second-2 dust-proof mount (500b) that is closer to the discharge pipe (300) than to the suction pipe (200). That is, the second-1 dust-proof mount (500a) is placed on the motor housing (120), and the second-2 dust-proof mount (500b) is placed on the compression housing (140).

[0059] In this embodiment, a pair of first anti-vibration mounts (400) have the same installation angle with respect to the center vertical plane (VS), and a pair of second anti-vibration mounts (500) also have the same installation angle with respect to the center vertical plane (VS). Furthermore, as shown in FIG. 4, a pair of first anti-vibration mounts (400) are arranged parallel to each other, and a pair of second anti-vibration mounts (500) are also arranged parallel to each other. That is, each first anti-vibration mount (400) is installed in the housing (100) side by side with the same installation position and installation angle, and each second anti-vibration mount (500) is also installed in the housing (100) side by side with the same installation position and installation angle.

[0060] In particular, in this embodiment, the first anti-vibration mount (400) and the second anti-vibration mount (500) have an asymmetrical installation height or an installation angle with respect to the center vertical plane (VS). Here, the installation height of the anti-vibration mount refers to the height of the point where the anti-vibration mount and the protruding lug come into contact, and the installation angle refers to the angle formed by the longitudinal direction in which the anti-vibration mount extends toward the protruding lug and a straight line perpendicular to the ground.

[0061] First, regarding the installation height, in this embodiment, the first connection position (Lm1) where the center extension line of the first vibration-damping mount (400) meets the housing (100) is positioned lower than the position (Lp) of the integrated pipe, and the second connection position (Lm2) where the center extension line of the second vibration-damping mount (500) meets the housing (100) is positioned lower than the first connection position (Lm1).

[0062] At this time, since the location (Lp) of the integrated pipe is positioned on the second side, the first connection location (Lm1) is positioned on the opposite side from the location (Lp) of the integrated pipe. On the other hand, the second connection location (Lm2) is positioned on the opposite side from the first connection location (Lm1), but on the same side as the location (Lp) of the integrated pipe.

[0063] At this time, it is preferable that the position (Lp) of the integrated piping and the second connection position (Lm2) are symmetrical with respect to the center horizontal plane (HS) of the housing (100). This allows even axial rolling to be suppressed.

[0064] Next, regarding the installation angle, both the first anti-vibration mount (400) and the second anti-vibration mount (500) are positioned at an angle with respect to the center vertical plane (VS), and the installation angle (a) of the first anti-vibration mount (400) is greater than the installation angle (b) of the second anti-vibration mount (500). (a>b)

[0065] As shown in FIG. 1, since the compressor rotates around the longitudinal axis, the rolling mode appears most strongly. Therefore, by arranging the first and second anti-vibration mounts (400, 500) at an angle as described above, the rolling mode and resonance of the compressor can be suppressed.

[0066] Consequently, the horizontal and vertical reaction forces of the elastic modulus (Kp1) of the suction pipe (200), the elastic modulus (Kp2) of the discharge pipe (300), the elastic modulus (Km1) of the first anti-vibration mount (400), and the elastic modulus (Km2) of the second anti-vibration mount (500) cancel each other out. Accordingly, it is ultimately desirable that the sum of the horizontal reaction forces and the sum of the vertical reaction forces are both zero. In general, the elastic modulus (Km1) of the first anti-vibration mount (400) and the elastic modulus (Km2) of the second anti-vibration mount (500) will be relatively larger than the elastic modulus (Kp1) of the suction pipe (200) or the elastic modulus (Kp2) of the discharge pipe (300).

[0067] As described above, when a pair of first dustproof mounts (400) and a pair of second dustproof mounts (500) are provided and the suction pipe (200) and discharge pipe (300) are integrated into a single virtual integrated pipe, the horizontal reaction type (1) and the vertical reaction type (2) can be derived as follows.

[0068] Horizontal reaction type (1) -----

[0069] Vertical reaction force type (2) -----

[0070] At this time, as shown in FIG. 5, angle α (which can also be expressed as 90-a) is the angle formed by the first anti-vibration mount (400) with respect to the center horizontal plane (HS) of the housing (100), angle β (which can also be expressed as 90-b) is the angle formed by the second anti-vibration mount (500) with respect to the center horizontal plane (HS), and angle γ is the angle formed by the integrated pipe with respect to the center horizontal plane (HS).

[0071] In this way, since the suction pipe (200) and discharge pipe (300) connected to the housing also have a certain portion of elastic modulus and can perform a vibration damping function, the horizontal and vertical equilibrium of the compressor can be accurately created by considering the elastic modulus of the suction pipe (200) and discharge pipe (300). As a result, the vibration damping characteristics of the compressor can be enhanced.

[0072]

[0073] Next, with reference to FIG. 6, we will examine an electric compressor installation structure having a dustproof mount according to a second embodiment of the present invention.

[0074] An electric compressor having a dustproof mount according to the second embodiment includes, in the same manner as the first embodiment, a housing (100), a suction pipe (200), a discharge pipe (300), a first dustproof mount (400), and a second dustproof mount (500). The electric compressor according to the second embodiment has the same structure as the electric compressor according to the first embodiment, except for the installation angle of the second dustproof mount (500). Therefore, the explanation will focus only on the differences.

[0075] In this embodiment, the second dust-proof mount (500) is positioned vertically for the assembly of the electric compressor. That is, the installation angle of the second dust-proof mount (500) with respect to the center vertical plane (VS) is 0°. At this time, the first dust-proof mount (400) is still positioned at an angle with respect to the center vertical plane (VS). In some cases, the first dust-proof mount (400) may be positioned horizontally.

[0076] As a result, the same effect as the first embodiment can be achieved while increasing the assembly ease of the electric compressor.

[0077]

[0078] Next, with reference to FIGS. 7 to 9, we will examine an electric compressor installation structure having a dustproof mount according to a third embodiment of the present invention.

[0079] An electric compressor having a dustproof mount according to the third embodiment includes a housing (100), a suction pipe (200), a discharge pipe (300), a first dustproof mount (400), and a second dustproof mount (500), in the same manner as in the first embodiment. However, in the electric compressor according to the third embodiment, the first dustproof mount (400) and the second dustproof mount (500) are symmetric with respect to the center vertical plane (VS). That is, the installation height and the installation angle with respect to the center vertical plane (VS) of the first dustproof mount (400) and the second dustproof mount (500) are the same. Therefore, the first dustproof mount (400) and the second dustproof mount (500) will be described in detail.

[0080] In this embodiment, the first anti-vibration mount (400) and the second anti-vibration mount (500) are arranged symmetrically with respect to the center vertical plane (VS). That is, as shown in FIG. 9, regarding the installation height, the first connection position (Lm1) where the center extension line of the first anti-vibration mount (400) meets the housing (100) and the second connection position (Lm2) where the center extension line of the second anti-vibration mount (500) meets the housing (100) are arranged at the same height. At this time, it is preferable that the position (Lp) of the integrated pipe and the second connection position (Lm2) are symmetrical with respect to the center horizontal plane (HS) of the housing (100).

[0081] In addition, regarding the installation angle, the first anti-vibration mount (400) and the second anti-vibration mount (500) are each positioned at an angle with respect to the center vertical plane (VS), and the installation angle (a) of the first anti-vibration mount (400) and the installation angle (b) of the second anti-vibration mount (500) are the same. (a=b)

[0082] In particular, in this embodiment, the elastic moduli of the first anti-vibration mount (400) and the second anti-vibration mount (500) are different from each other. Specifically, the elastic modulus (Km1) of the first anti-vibration mount (400) is greater than the elastic modulus (Km2) of the second anti-vibration mount (500). (Km1 > Km2)

[0083] As a result, the sum of the horizontal reaction forces of the elastic modulus (Kp1) of the suction pipe (200), the elastic modulus (Kp2) of the discharge pipe (300), the elastic modulus (Km1) of the first anti-vibration mount (400), and the elastic modulus (Km2) of the second anti-vibration mount (500) cancel each other out, and the sum of the vertical reaction forces is all 0.

[0084]

[0085] Next, with reference to FIG. 10, we will examine an electric compressor installation structure having a dustproof mount according to the fourth embodiment of the present invention.

[0086] An electric compressor having a dustproof mount according to the fourth embodiment includes, in the same manner as the first embodiment, a housing (100), a suction pipe (200), a discharge pipe (300), a first dustproof mount (400), and a second dustproof mount (500). In addition, a pair of first dustproof mounts (400) are similarly spaced apart along the longitudinal direction of the housing (100) on the first side, and a pair of second dustproof mounts (500) are spaced apart along the longitudinal direction of the housing (100) on the second side. However, in the electric compressor according to the fourth embodiment, the pair of first dustproof mounts (400) are not parallel to each other, and the pair of second dustproof mounts (500) are also not parallel to each other. The first dustproof mount (400) and the second dustproof mount (500) will be described in detail below.

[0087] In this embodiment, as shown in FIG. 10, a pair of second anti-vibration mounts (500) have the same installation height and an installation angle relative to the center vertical plane (VS), but the pair of second anti-vibration mounts (500) are installed at an angle such that they become closer to each other with respect to the longitudinal direction of the housing (100) as they move upward in the direction of gravity. That is, when viewing the pair of second anti-vibration mounts (500) from the second side, the second-1 anti-vibration mount (500a) is installed at an angle a' to the right in the drawing as it moves upward in the direction of gravity, while the second-2 anti-vibration mount (500b) is installed at an angle b' to the left in the drawing as it moves upward in the direction of gravity, in the opposite direction to the second-1 anti-vibration mount (500a). At this time, the second-1 anti-vibration mount (500a) and the second-2 anti-vibration mount (500b) may be tilted to the same degree. (a'=b')

[0088] Likewise, although not illustrated, a pair of first dustproof mounts (400) also have the same installation height and installation angle with respect to the center vertical plane (VS), but the pair of first dustproof mounts (400) are installed at an angle such that they become closer to each other with respect to the longitudinal direction of the housing (100) as they move upward in the direction of gravity.

[0089] Accordingly, the pitching mode of the compressor as illustrated in FIG. 1 can also be canceled out by restricting movement. As a result, the pitching mode and resonance of the compressor can also be suppressed.

[0090]

[0091] Finally, with reference to FIG. 11, we will examine an electric compressor installation structure having a dustproof mount according to the fifth embodiment of the present invention.

[0092] An electric compressor having a dustproof mount according to the fifth embodiment includes, in the same manner as the first embodiment, a housing (100), a suction pipe (200), a discharge pipe (300), a first dustproof mount (400), and a second dustproof mount (500). In addition, a pair of first dustproof mounts (400) are similarly spaced apart along the longitudinal direction of the housing (100) on the first side, and a pair of second dustproof mounts (500) are spaced apart along the longitudinal direction of the housing (100) on the second side. However, in the electric compressor according to the fifth embodiment, the installation angles of the pair of first dustproof mounts (400) with respect to the center vertical plane (VS) are not the same, and the installation angles of the pair of second dustproof mounts (500) with respect to the center vertical plane (VS) are not the same. The first dustproof mount (400) and the second dustproof mount (500) will be described in detail below.

[0093] In this embodiment, the installation angles of a pair of first anti-vibration mounts (400) with respect to the center vertical plane (VS) are different from each other, and the installation angles of a pair of second anti-vibration mounts (500) with respect to the center vertical plane (VS) are different from each other.

[0094] In addition, although not limited thereto, in this embodiment, the installation height of a pair of first anti-vibration mounts (400) is the same as that of a pair of second anti-vibration mounts (500). When viewing a pair of first anti-vibration mounts (400) from a first side, the first-1 anti-vibration mount (400a) is parallel to the first-2 anti-vibration mount (400b), and when viewing a pair of second anti-vibration mounts (500) from a second side, the second-1 anti-vibration mount (500a) is parallel to the second-2 anti-vibration mount (500b).

[0095] Consequently, the sum of the horizontal reaction forces and the sum of the vertical reaction forces of the elastic modulus (Kp1) of the suction pipe (200), the elastic modulus (Km1) of the first-1 vibration damping mount (400a), and the elastic modulus (Km2) of the second-1 vibration damping mount (500a) cancel each other out and are all zero. At the same time, the sum of the horizontal reaction forces and the sum of the vertical reaction forces of the elastic modulus (Kp2) of the discharge pipe (300), the elastic modulus (400b) of the first-2 vibration damping mount, and the elastic modulus (500b) cancel each other out and are all zero.

[0096] Accordingly, as in the first to fourth embodiments above, the entire compressor may be in a state of equilibrium, but as in the fifth embodiment, the suction pipe (200) and discharge pipe (300) portions of the compressor may each be in a state of equilibrium.

[0097] The present invention is not limited to the specific embodiments and descriptions described above, and various modifications can be made by anyone with ordinary knowledge in the technical field to which the present invention pertains without departing from the essence of the invention as claimed in the claims, and such modifications fall within the scope of protection of the present invention.

[0098] The present invention relates to an electric compressor installation structure having a vibration damping mount, and more specifically, to an electric compressor installation structure in which a first vibration damping mount disposed on one side of the electric compressor and a second vibration damping mount disposed on the other side are asymmetrical or have different elastic moduli to achieve a state of equilibrium by considering the elastic moduli of the suction pipe and the discharge pipe.
