[0033] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0034] The present invention provides a vibration damping device for a horizontal compressor, which not only has a good vibration damping effect in the vertical direction, but also has a very obvious vibration damping effect in the lateral direction, effectively solving the problem that the traditional vibration damping scheme cannot take into account both vertical and horizontal vibrations at the same time. The vibration damping device of the present invention can greatly reduce the difficulty of assembly. At the same time, the vibration damping plate, vibration damping foot pad, mounting plate and chassis are all tightly connected, and there is no need to set a limit for the vibration damping foot pad, thus avoiding collisions between the vibration damping foot pad and the machine foot and chassis, and reducing the noise of the air conditioner. In addition, this vibration damping device can also change the stiffness according to the vibration anomalies caused by problems such as the eccentricity of the compressor's center of mass caused by the liquid storage tank, and can also design the stiffness of the vibration damping spring plate according to the vibration magnitude in the vertical and lateral directions.

[0035] like Figure 1-Figure 4 As shown, the vibration damping device for a horizontal compressor provided by the present invention includes: a first vibration damping elastic plate 10 and a second vibration damping elastic plate 20.

[0036] The first vibration-damping elastic plate 10 and the second vibration-damping elastic plate 20 are used to support the opposite sides of the horizontal compressor 70. The first vibration-damping elastic plate 10 and the second vibration-damping elastic plate 20 are split structures, that is, two components. The horizontal compressor 70 has a horizontal centerline O( Figure 1 As shown, the horizontal centerline O is an imaginary line extending axially along the housing of the horizontal compressor 70 and may be parallel to the cylinder centerline of the horizontal compressor 70. The first and second vibration-damping elastic plates 10, 20 may be symmetrically arranged about the horizontal centerline O of the horizontal compressor 70, i.e., symmetrically supported on both sides of the horizontal compressor 70 in the transverse direction x. The first and second vibration-damping elastic plates 10, 20 may both extend along the horizontal centerline O of the horizontal compressor to form long, strip-shaped vibration-damping elastic plates.

[0037] The first vibration-damping elastic plate 10 is formed into a first step structure, and the second vibration-damping elastic plate 20 is formed into a second step structure, and the first step structure and the second step structure extend toward each other. Figure 1 As shown, in the vertical direction y, the first step structure and the second step structure have a certain height, and the two step structures extend upward in the vertical direction y while also extending toward each other, that is, extending in directions close to each other, thereby forming a stepped bent step structure. A space with a horizontal direction and a vertical direction is formed between the first step structure and the second step structure, so that the horizontal compressor 70 is suspended and supported in the space between the first step structure and the second step. In the following description, the first step structure can be represented by the first step structure 10, and the second step structure can be represented by the second step structure 20.

[0038] Specifically, the first step structure 10 includes alternately connected first horizontal plates 11 and first vertical plates 12, and the number of the first horizontal plates 11 and the first vertical plates 12 are n first horizontal plates 11 and n-1 first vertical plates 12 respectively. The second step structure 20 includes alternately connected second horizontal plates 21 and second vertical plates 22, and the number of the second horizontal plates 21 and the second vertical plates 22 are n second horizontal plates 21 and n-1 second vertical plates 22 respectively, where n≥2. The first vertical plates 12 and the second vertical plates 22 are used to suppress the lateral vibration of the horizontal compressor 70, and the first horizontal plates 11 and the second horizontal plates 21 are used to suppress the vertical vibration of the horizontal compressor 70.

[0039] For example, if Figure 1 and Figure 2 As shown, the first step structure 10 is used as an example for explanation. The second step structure 20 can be similar to the first step structure 10. The first step structure 10 includes three first transverse plates 11 and two first vertical plates 12, which are connected in sequence from bottom to top in the vertical direction y, namely the first first transverse plate 11-1, the first first vertical plate 12-1, the second first transverse plate 11-2, the second first vertical plate 12-2, and the third first transverse plate 11-3. One side of the horizontal compressor 70 can be supported on the third first transverse plate 11-3, and the first first transverse plate 11-1 can be fixed to the chassis of the compressor. The first first vertical plate 12-1 and the second first vertical plate 12-2 can have a good vibration reduction effect in the horizontal direction (transverse direction x), and the second first transverse plate 11-2 can have a good vibration reduction effect in the vertical direction (vertical direction y). The above-mentioned first step structure only exemplarily shows 3 first horizontal plates 11 and 2 first vertical plates 21, but is not limited to this. The number of first horizontal plates 11 can be 2, 4, 5, 6...n, and the number of first vertical plates 21 can be 1, 3, 4, 5...n-1.

[0040] When the compressor generates vertical y vibration, the second first horizontal plate 11-2 plays a major role in reducing vibration. As the amplitude increases, the vertical stiffness of the second first horizontal plate 11-2 also increases, and the restriction on the vertical vibration of the compressor becomes stronger and stronger; when the compressor generates horizontal vibration (transverse direction x), the first first vertical plate 12-1 and the second first vertical plate 12-2 play a major role in reducing vibration, and the two sections of elastic plates are a series structure, and the stiffness is less than the stiffness of any one of the two sections of the spring. As the horizontal amplitude of the compressor increases, the stiffness of the first first vertical plate 12-1 and the second first vertical plate 12-2 connected in series also increases, and the spring plate's restriction on the horizontal vibration of the compressor becomes stronger and stronger.

[0041] The vibration reduction device for a horizontal compressor provided by the present invention not only has a good vibration reduction effect in the vertical direction, but also has a very obvious vibration reduction effect in the lateral direction, effectively solving the problem that traditional vibration reduction schemes cannot take into account vibrations in both vertical and horizontal directions at the same time.

[0042] In some embodiments, at least one first vertical plate 12 and / or at least one second vertical plate 22 is provided with a hollow structure 40; and / or, at least one first horizontal plate 11 and / or at least one second horizontal plate 21 is provided with a hollow structure 40. By providing the hollow structure 40, the stiffness of the first vibration-damping elastic plate 10 and the second vibration-damping elastic plate 20 can be adjusted. The stiffness of the vibration-damping structure can be adjusted according to the structural characteristics of the compressor and other power devices, the vibration isolation rate of the vibration-damping structure can be increased, and the vibration transmitted from the compressor to the chassis can be reduced. For example, the stiffness can be adjusted by providing an adaptive hollow structure on the first vibration-damping elastic plate 10 and the second vibration-damping elastic plate 20 to solve the abnormal vibration problem caused by the eccentricity of the compressor center of mass caused by the compressor liquid storage tank. At the same time, the stiffness of the vibration-damping spring plate can be designed according to the vibration magnitude in the vertical and horizontal directions. The shape of the hollow structure 40 can be a variety of shapes such as rectangle, circle, triangle, etc.

[0043] In some embodiments, as Figure 1As shown, the vibration damping device also includes: a mounting plate 30 for supporting the horizontal compressor 70, the mounting plate 30 being fixed between the first vibration damping elastic plate 10 and the second vibration damping elastic plate 20. In one example, the mounting plate 30 and the first step structure 10 and the second step structure 20 can be separate bodies, for example, the first side 31 of the mounting plate 30 is fixed to the nth first transverse plate 11 of the first step structure 10 by a first fastener 61, and the first first transverse plate 11 of the first step structure 10 is used for fixed connection, for example, fixed to the compressor chassis. The second side 32 of the mounting plate 30 is fixed to the nth second transverse plate 21 of the second step structure 20 by a second fastener 62, and the first second transverse plate 21 of the second step structure is used for fixed connection, for example, fixed to the compressor chassis, wherein the first side 31 and the second side 32 are opposite to each other. In another example, the mounting plate 30 and the first step structure 10 and the second step structure 20 can be integrally formed.

[0044] Furthermore, the mounting plate 30 is formed with a recess for accommodating a portion of the horizontal compressor 70. The recess 301 is suspended in the space formed between the first vibration-damping elastic plate 10 and the second vibration-damping elastic plate 20. The mounting plate 30 may be generally U-shaped, with the recess 301 including a bottom wall 33, and first and second side walls 34, 35 extending upward from either side of the bottom wall 33. The first and second side walls 34, 35 are bent in directions away from each other to form a first side edge 31 and a second side edge 32.

[0045] Furthermore, a shock-absorbing pad 50 is provided between the first side 31 and the nth first transverse plate 11; and a shock-absorbing pad 50 is provided between the second side 32 and the nth second transverse plate 12. The shock-absorbing pad 50 can be, for example, a rubber pad. Specifically, the shock-absorbing pad 50 provided between the first side 31 and the nth first transverse plate 11 has a through hole for passing a first fastener 61 therethrough to secure the first side 31 of the mounting plate 30 to the nth second transverse plate 12, thereby securing the shock-absorbing pad 50 between the first side 31 of the mounting plate 30 and the nth first transverse plate 11. Similarly, the shock-absorbing pad 50 provided between the second side 32 and the nth second transverse plate 21 has a through hole for passing a second fastener 62 therethrough to secure the second side 32 of the mounting plate 30 to the nth second transverse plate 22, thereby securing the shock-absorbing pad 50 between the second side 32 of the mounting plate 30 and the nth second transverse plate 22.

[0046] In summary, in a preferred embodiment, the compressor's legs can be secured in grooves in the mounting plate 30. Due to the compressor's own weight, the first and second damping elastic plates 10, 20 deform. The product of the vertical stiffness of the first and second damping elastic plates 10, 20, and the damping pad 50 and their vertical displacement equals the mass of the compressor. When the air conditioner is operating, the compressor's internal rotor generates vertical and horizontal vibrations. Furthermore, the vehicle in which the air conditioner is installed can also experience vertical and horizontal vibrations due to uneven road conditions or sudden braking. When the compressor generates vertical y vibration, the second first horizontal plate 11-2 plays a major role in reducing vibration. As the amplitude increases, the vertical stiffness of the second first horizontal plate 11-2 also increases, and the restriction on the vertical vibration of the compressor becomes stronger and stronger; when the compressor generates horizontal vibration (transverse direction x), the first first vertical plate 12-1 and the second first vertical plate 12-2 play a major role in reducing vibration, and the two sections of elastic plates are a series structure, and the stiffness is less than the stiffness of any one of the two sections of the spring. As the horizontal amplitude of the compressor increases, the stiffness of the first first vertical plate 12-1 and the second first vertical plate 12-2 connected in series also increases, and the spring plate's restriction on the horizontal vibration of the compressor becomes stronger and stronger.

[0047] like Figure 5a 、 Figure 5b 、 Figure 6a and Figure 6b As shown, the vibration reduction effect of the first vibration-damping elastic plate 10 and the second vibration-damping elastic plate 20 was verified. CAE simulation verification was performed based on the model in the implementation case, and the stress of the chassis using only rubber foot pads was compared to verify the vibration reduction effect of using both the vibration-damping elastic plate and the rubber foot pads. Figure 5a 、 Figure 5b From the horizontal X (horizontal) chassis stress cloud diagram, it can be seen that the combination of the vibration-damping elastic plate and the rubber foot pad of the present invention ( Figure 5a ), the maximum stress is located at the bolt fixing on the left side of the compressor, the maximum stress is 8.2Mpa, the chassis with rubber foot pads ( Figure 5b ) The maximum stress position is at the compressor axial screw, with a maximum stress of 10.4Mpa. Under lateral X random vibration, the combined chassis stress of the spring plate and rubber foot pad is relatively small. Figure 6a and Figure 6b From the vertical Y (vertical) chassis stress cloud diagram, it can be seen that the combination of the vibration-damping elastic plate and the rubber foot pad of the present invention ( Figure 6a ), the maximum stress is located at the axial position of the compressor, the maximum stress is 10.2Mpa, and the chassis using only rubber pads ( Figure 6b) The maximum stress position is at the axial screw of the compressor, with a maximum stress of 34.7 MPa. Under vertical Y-axis random vibration, the chassis stress of the combination of vibration-damping elastic plate and rubber foot pad is much smaller than that of the solution using rubber foot pad alone.

[0049] The horizontal compressor further comprises: a compressor chassis, wherein the first first transverse plate 11 of the first step structure is fixed on the chassis, and the first second transverse plate 21 of the second step structure is fixed on the chassis.

[0050] The horizontal compressor provided by the present invention not only has a good vibration reduction effect in the vertical direction, but also has a very obvious vibration reduction effect in the lateral direction, which effectively solves the problem that traditional vibration reduction solutions cannot take into account both vertical and horizontal vibrations at the same time. In addition, the difficulty of assembly can be greatly reduced. At the same time, the vibration reduction plate, vibration reduction foot pad, mounting plate and chassis are all tightly connected, and there is no need to set a limit for the vibration reduction foot pad, which avoids collisions between the vibration reduction foot pad and the machine foot and chassis, reducing the noise of the air conditioner. The stiffness can also be changed according to the vibration anomalies caused by problems such as the eccentricity of the compressor's center of mass caused by the liquid storage tank. At the same time, the stiffness of the vibration reduction spring plate can be designed according to the vibration magnitude in the vertical and lateral directions.

[0051] The compressor includes a liquid reservoir 71 connected to the compressor's intake port and an exhaust line 72. To address vibration issues caused by the compressor's center of mass eccentricity due to the liquid reservoir 71, the stiffness of the first and second damping spring plates 10 and 20 can be adjusted by providing appropriate hollow structures and dimensions. The stiffness of the damping spring plates can also be designed based on the vibration levels in the vertical and horizontal directions. The hollow structure 40 can be shaped in a variety of ways, including rectangular, circular, and triangular.
