[0026] In the description of the application, it should be noted that the terms "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the application.

[0027] In the description of the present application, it is necessary to point out that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "contacting", "communication" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0028] The present application provides a horizontal compressor with damping device, which can realize the better vertical damping effect of the horizontal compressor through the cooperation of the bearing limiting assembly and the spring damping device, and can limit the compressor in the horizontal direction, effectively suppress the horizontal swing, improve the stability of the horizontal compressor and reduce the noise.

[0029] As shown in Figure 1 and Figure 2 The horizontal compressor with damping device of the present application comprises a compressor body 10, a spring damping device 20 and a bearing limiting assembly.

[0030] The compressor body 10 has opposite first end 101 and second end 102 in the axial direction, wherein the axial direction is Figure 1 the central axis O, and can be parallel or coincident with the axial direction of the cylinder of the horizontal compressor.

[0031] The spring damping device 20 supports the bottom of the compressor body 10. For example, it is supported on the bottom support of the compressor body 10, specifically, the spring damping device 20 can be located between the bottom support of the compressor body 10 and the bottom plate. The spring damping device 20 can effectively suppress the vertical vibration of the compressor body 10 during operation.

[0032] The bearing limiting assembly comprises a first bearing assembly 31 arranged at the first end 101 and a second bearing assembly 32 arranged at the second end 102. The first bearing assembly 31 comprises a first bearing 311 and a first fixed shaft 312. The outer ring of the first bearing 311 is fixed at the first end 101, and one end of the first fixed shaft 312 is installed in the inner ring of the first bearing 311 to form an interference fit, and the other end is fixedly connected, for example, to a side support of the chassis or to other fixed structures. The second bearing assembly 32 comprises a second bearing 321 and a second fixed shaft 322. The outer ring of the second bearing 321 is fixed at the second end 102, and one end of the second fixed shaft 322 is installed in the inner ring of the second bearing 321 to form an interference fit, and the other end is fixedly connected, for example, to the other side support of the chassis or to other fixed structures. The first bearing assembly 31 and the second bearing assembly 32 cooperate to limit the horizontal displacement of the compressor body 10 and have a certain degree of rotational freedom. Thus, when the spring damping device 20 exerts a force on the compressor to reduce vibration, the horizontal displacement of the compressor is effectively inhibited, allowing the spring damping device 20 to reduce vibration in the vertical direction of the compressor more effectively, avoiding the shaking of the compressor, improving the stability of the horizontal compressor, and reducing noise. The present application uses bearings to limit the horizontal displacement of the horizontal compressor, and the low stiffness of the spring damping device 20 to achieve sound insulation and vibration reduction, meeting the vibration isolation requirements of the compressor while limiting its horizontal displacement. In addition, there is friction and damping between the bearing steel balls and the steel balls, and between the steel balls and the lubricating oil, which can further dissipate energy and further improve the vibration absorption effect.

[0033] In some embodiments, the first bearing 311, the first fixed shaft 312, the second bearing 321, and the second fixed shaft 322 are arranged on the same axis. Further, the first bearing 311, the first fixed shaft 312, the second bearing 321, and the second fixed shaft 322 all coincide with the central axis O of the compressor body 10, for example, with the cylinder axis in the compressor. To ensure that the compressor can rotate freely along its axis O during operation due to the imbalance of the load and driving torque, while not transmitting too much vibration to the fixed end due to uneven rotation.

[0034] In some embodiments, the spring damping assembly 20 comprises a first spring damping assembly and a second spring damping assembly. The first spring damping assembly is supported on the first leg 11 near the first end 101 of the bottom of the compressor body 10, and the second spring damping assembly is supported on the second leg 12 near the second end 102 of the bottom of the compressor body 10. The first spring damping assembly and the second spring damping assembly can have the same structure. The height difference between the first spring damping assembly and the second spring damping assembly is calculated according to the installation inclination angle of the compressor body. The first spring damping assembly and the second spring damping assembly are located on both sides of the center of gravity of the compressor.

[0035] The first spring damping assembly comprises a first mounting plate 21, a first spring foot pad 22 and a second spring foot pad 23, the first mounting plate 21 is fixedly connected with the first leg 11, and the first spring foot pad 22 and the second spring foot pad 23 are respectively arranged on the left and right sides of the bottom of the first mounting plate 21, wherein the first spring foot pad 22 is close to the left side edge 103 of the top view projection of the compressor body 10 shell, and the second spring foot pad 23 is close to the right side edge 104 of the top view projection of the compressor body 10 shell, so that the left-right span between the first spring foot pad 22 and the second spring foot pad 23 is larger. The first spring foot pad 22 and the second spring foot pad 23 can be arranged symmetrically left and right relative to the central axis O of the compressor body 10.

[0036] The second spring damping assembly comprises a second mounting plate, a third spring foot pad 24 and a fourth spring foot pad 25, the mounting plate is fixedly connected with the second leg, the third spring foot pad and the fourth spring foot pad are respectively arranged on the left and right sides of the second mounting plate, wherein the third spring foot pad is close to the left side edge of the top view projection of the compressor body shell, and the fourth spring foot pad is close to the right side edge of the top view projection of the compressor body shell. So that the left-right span between the third spring foot pad and the fourth spring foot pad is larger. The third spring foot pad and the fourth spring foot pad can be arranged symmetrically left and right relative to the central axis O of the compressor body 10.

[0037] Combining Figure 2 and Figure 3 As shown in the drawings, the first spring foot pad 22 is close to the left side edge 103 of the top view projection of the compressor body 10 shell, and the second spring foot pad 23 is close to the right side edge 104 of the top view projection of the compressor body 10 shell, so that the left-right span between the first spring foot pad 22 and the second spring foot pad 23 is larger. And the third spring foot pad 24 is close to the left side edge of the top view projection of the compressor body shell, and the fourth spring foot pad 25 is close to the right side edge of the top view projection of the compressor body shell. So that the left-right span between the third spring foot pad 24 and the fourth spring foot pad 25 is larger. In this way, when the compressor rotates around its axis O direction, on the compressor mounting plate (first mounting plate and second mounting plate), the movement component is mainly vertical, and each spring foot pad mainly bears the vibration excitation from the vertical direction of the compressor. At this time, each spring foot pad can play a better vibration isolation effect, and at the same time, due to the limiting effect of the first bearing 311 and the second bearing 321 on the horizontal direction of the compressor, the compressor will not produce larger displacement, so as to ensure its good damping, and at the same time, it will not produce larger displacement due to small spring stiffness and damage to other structures connected with the compressor.

[0038] In some embodiments, the first mounting plate 21 is provided with a first accommodating groove extending in the left-right direction, and the upper foot pad 221 of the first spring foot pad 22 and the upper foot pad 231 of the second spring foot pad 23 are at least partially located in the first accommodating groove. The first spring foot pad 22 further comprises a lower foot pad 223 and a first spring 222 located between the upper foot pad 221 and the lower foot pad 223, and the lower foot pad 223 can be fixed on the bottom plate. The second spring foot pad 23 further comprises a lower foot pad 233 and a second spring 232 located between the upper foot pad 231 and the lower foot pad 233, and the lower foot pad 233 can be fixed on the bottom plate. The second mounting plate is provided with a second accommodating groove extending in the left-right direction, and the upper foot pad of the third spring foot pad and the upper foot pad of the fourth spring foot pad are at least partially located in the second accommodating groove.

[0039] In some embodiments, the bottom plate is further provided with a first support and a second support located on both sides of the compressor body 10 in the axial direction, the first fixed shaft is fixed to the first support, and the second fixed shaft is fixed to the second support.

[0040] The application also provides an air conditioner for a vehicle, comprising the horizontal compressor with the damping device according to any one of the above embodiments.

[0041] The air conditioner for a vehicle of the application can realize the optimal vertical damping effect of the horizontal compressor through the cooperation of the bearing limiting assembly and the spring damping device, and can limit the compressor in the horizontal direction, effectively suppress the horizontal shaking of the compressor, and improve the stability of the horizontal compressor, thereby reducing the noise of the air conditioner.
