Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
A mounting system 10 for a mobile refrigerator compressor according to a first aspect of the present invention is described below with reference to the accompanying drawings.
Fig. 1-3 show a first embodiment of a mounting system 10 according to a first aspect of the invention. In particular, the mounting system 10 comprises a mounting frame 11 for the compressor 1 and a mounting plate 12 to which the mounting frame 11 and the compressor 1 are fixed. The mounting frame 11 comprises a bottom 13 and four mounting portions 14, wherein the bottom of the mounting frame 11 is arranged at the bottom of the compressor 1; the four mounting portions 14 include extensions 15 and mounting members 16. The extension 15 of the mounting portion 14 extends from the bottom 13 of the mounting frame 11 in a direction substantially parallel to the longitudinal center axis of the compressor 1, preferably to a position substantially close to the center of gravity of the compressor, more preferably to a position at which the center of gravity of the compressor is located (substantially at the center of the compressor in the height direction), while the mounting piece 16 extends from the upper end of the extension 15 away from the longitudinal center axis in a direction substantially perpendicular to the longitudinal center axis of the compressor 1, so that the mounting piece 16 can be preferably disposed at a position substantially close to the center of gravity of the compressor, more preferably at a position at which the center of gravity of the compressor is located, that is, substantially at the center of the compressor in the height direction. Each of the mounting pieces is provided with a through hole 20 for attaching a rubber foot pad, wherein the through hole allows the upper end of the rubber foot pad to pass through, and the rim of the through hole of the mounting piece 16 is snapped into the recess of the rubber foot pad, thereby achieving attachment of the mounting piece 16 to the rubber foot pad. The rubber foot may be hollow or a through hole for securing to the mounting plate 12 by a pin snap or a screw nut, respectively. In addition, the mounting plate 12 is provided with a plurality of through holes 20 for attaching rubber pads, wherein the through holes allow the upper ends of the rubber pads to pass through, and the rims of the through holes on the mounting plate 12 are snapped into the recesses of the rubber pads, so that the mounting plate 12 is attached to the rubber pads. The rubber foot pad can be hollow or a through hole, so that the rubber foot pad can be fixed on the bottom fixing piece 7 of the mobile refrigerator through a pin shaft buckle or a screw nut respectively.
The mounting system comprises two mounting structures, namely a mounting frame and a mounting plate, wherein the mounting frame and the mounting plate are arranged in a superposed manner with a bottom fixing piece through rubber foot pads, so that the foot pads for fixing the mounting frame on the mounting plate form a first-stage damping vibration attenuation foot pad, and the foot pads for fixing the mounting plate on the bottom fixing piece of the mobile refrigerator additionally form a second-stage damping vibration attenuation foot pad. Therefore, the mounting system can effectively increase the elasticity of the system, adjust the vibration damping of the system, gradually attenuate the vibration and impact on the movable refrigerator for the vehicle, prolong the service life of the compressor and reduce NVH.
Furthermore, the first embodiment of the mounting system 10 is particularly suited for use with compressors having a high aspect ratio (i.e., a high center of gravity), such as rotary compressors. Because the mounting portion 14 in this mounting system 10 enables the mounting piece 16 to be disposed close to the center of gravity of the compressor due to the provision of the extension portion 15, the compressor is arranged on the mounting plate 12 in such a manner that the center of gravity is lowered, and amplification of vibration and shock due to high center of gravity mounting can be avoided. This can be used to further attenuate the vibration and shock to which a mobile refrigerator for a vehicle is subjected, extend the life of the compressor, and reduce NVH.
Additionally or alternatively, in one implementation of the first embodiment of the mounting system 10, as shown in fig. 1 or 3, the mounting plate 12 of the mounting system 10 may be substantially Z-shaped, thereby comprising two parts, namely a first upper part 17 and a second lower part 18. When the compressor 1 is mounted and fixed, the compressor 1 is mounted and fixed on the first upper portion 17 by the mounting frame 11 via a rubber foot pad. The first upper part 17 correspondingly has an opening 19 for receiving the part of the compressor located below the mounting 16. In addition, the first upper portion 17 has four through holes 20 provided around the opening 19 for attaching rubber pads, and the mounting plate 12 is mounted and fixed on the bottom fixture 7 of the mobile refrigerator via the rubber pads attached to the first upper portion 17. The mounting plate is structured such that when the mounting portion 14 having the extension portion 15 is mounted and fixed thereto, a foot pad of a conventional size (i.e., a conventional height) for fixing the mounting portion without the extension portion can be used without using a foot pad elongated in the height direction. In addition, the structure of the mounting plate can also reduce the height of the compressor 1 arranged in the mobile refrigerator.
Alternatively, the space of the mounting plate 12 for accommodating the portion of the compressor located below the mounting portion 14 may be a groove, a recess, or the like, in addition to the opening. Alternatively, in an alternative embodiment (not shown), the mounting plate 12 may not have a space for receiving a portion of the compressor below the mounting portion 14.
Additionally or alternatively, in one implementation of the first embodiment of the mounting system 10, as shown in fig. 1 and 3, the condenser assembly 4 and the fan 5 may be disposed on the second lower portion 18 of the mounting plate 12. In this embodiment, the compressor 1, the condenser assembly 4 and the fan 5 are all arranged on the mounting plate 12, so that the refrigeration assembly formed by the compressor 1, the condenser assembly 4 and the fan 5 can be integrated on the mounting system 10, forming a modular refrigeration assembly. The assembly of the entire refrigeration assembly can be completed when the mounting system 10 is secured to the bottom fixture 7 of the mobile refrigerator. Furthermore, since the condenser assembly 4 and fan 5 are disposed on the mounting plate 12, the additional second layer of damping feet that secure the mounting plate 12 to the mobile refrigerator base fixture 7 may also serve to dampen the vibrations and impacts to which the condenser assembly 4 and fan 5 are subjected.
Additionally or alternatively, in one implementation (not shown) of the first embodiment of the mounting system 10, the four mounting portions 14 are provided in substantially two parts. The first and second portions each include two mounting portions 14, the two mounting portions 14 of the first and second portions being disposed adjacent one another; the mounting portions of adjacent first portions are spaced further from the mounting portions of the second portions, for example, the angle between the mounting portions of adjacent first portions and the mounting portions of the second portions is greater than 90 °, preferably greater than 120 °. Preferably, the first and second portions are arranged symmetrically on opposite sides of the compressor 1 with respect to a longitudinal centre axis of the compressor. This arrangement of the mounting portion makes it possible to reduce the mounting space in the lateral direction, which is particularly advantageous for a vehicle-mounted, i.e., for an environment where the depth of the refrigerator is limited. This is because the side of the compressor between the first portion and the second portion can be directed toward the rear of the condenser when the compressor is fixedly installed behind the condenser, thereby reducing the occupation of space in the lateral direction (i.e., the thickness of the refrigerator) by the installation piece.
Figures 4-5 show a second embodiment of a mounting system 10 according to the first aspect of the invention. In particular, the mounting system 10 comprises a mounting frame 11 for the compressor 1 and a mounting plate 6 to which the mounting frame 11 and the compressor 1 are fixed. In this embodiment the mounting frame 11 does not comprise an extension, but only four mounting pieces 16, which mounting pieces 16 extend from the bottom of the compressor in a horizontal direction substantially perpendicular to the longitudinal centre axis of the compressor. Each of the mounting pieces is provided with a through hole 20 for attaching a rubber foot pad, wherein the through hole allows the upper end of the rubber foot pad to pass through, and the rim of the through hole of the mounting piece 16 is snapped into the recess of the rubber foot pad, thereby achieving attachment of the mounting piece 16 to the rubber foot pad. The rubber foot pad is hollow or a through hole, so that the rubber foot pad is fixed on the mounting plate through a pin shaft buckle or a screw nut respectively. In this embodiment, the mounting plate is substantially in the form of a flat plate 6. Four corners of the mounting plate 6 are respectively provided with a through hole 20 for attaching a rubber foot pad, wherein the through hole allows the upper end of the rubber foot pad to pass through, and the frame of the through hole on the mounting plate 6 is clamped into the concave of the rubber foot pad, so that the attachment of the mounting plate 6 and the rubber foot pad is realized. The rubber foot pad is hollow or a through hole so as to be fixed on a bottom fixing piece 7 of the mobile refrigerator through a pin shaft buckle or a screw nut respectively.
The mounting system includes two mounting structures, namely, a mounting frame and a mounting plate, which are vertically stacked with the bottom mount through rubber feet (i.e., disposed in line with the direction of the center of gravity of the compressor), so that a first layer of rubber feet is formed between the mounting frame and the mounting plate and a second layer of rubber feet is added between the mounting plate and the bottom mount of the mobile refrigerator, thereby forming a secondary vibration damping. The structure can improve the elasticity of the system, increase the damping of the system and reduce the natural frequency response of the compressor, so that the vibration is quickly attenuated and the NVH is reduced.
In a variation of the second embodiment of the mounting system, the mounting plate 6 may further adjust the number of through holes to adjust the number of secondary shock absorbing foot pads according to different shock absorbing requirements. For example, as shown in fig. 5, the mounting plate may be provided with four through-holes at the left and right sides of the compressor 1, respectively, so that the number of the second rubber pads may be increased to eight. This further increases the system elasticity, allowing rapid damping of vibrations.
Additionally or alternatively, in one implementation of the second embodiment of the mounting system 10, the condenser assembly 4 and fan 5 may be disposed on a mounting plate 6, as shown in fig. 4 and 5. In this embodiment, the compressor 1, the condenser assembly 4 and the fan 5 are all arranged on the mounting plate 6, so that the refrigeration assembly formed by the compressor 1, the condenser assembly 4 and the fan 5 can be integrated on the mounting system 10, forming a modular refrigeration assembly. The assembly of the entire refrigeration assembly can be completed when the mounting system 10 is secured to the bottom fixture 7 of the mobile refrigerator. In addition, since the condenser assembly 4 and the fan 5 are disposed on the mounting plate 6, the additional second rubber foot fixing the mounting plate 6 on the bottom fixing member 7 of the mobile refrigerator may also serve to attenuate the vibration and impact to which the condenser assembly 4 and the fan 5 are subjected.
Fig. 6-7 show a third embodiment of a mounting system 10 according to the first aspect of the invention. In particular, the mounting system 10 comprises a mounting frame 11 for the compressor 1 and a mounting plate 8 to which the mounting frame 11 and the compressor 1 are fixed. In this embodiment the mounting frame 11 is of the same construction as in the second embodiment and does not comprise extensions but only has four mounting members 16, which mounting members 16 extend from the bottom of the compressor in a horizontal direction substantially perpendicular to the longitudinal centre axis of the compressor. In this embodiment, the mounting plate 8 is of a different construction, including a first plate portion 81 and a second downwardly inclined portion 82. For example, as shown in fig. 6, the mounting plate 8 is provided with one second downward inclined portion 82 on each of opposite edges of the first plate portion 81, wherein each second downward inclined portion 82 has two through holes 20 for attaching rubber pads, respectively. Further, in this embodiment, the bottom mount 7 of the mobile refrigerator has a structure similar to that of the mount plate 8, and specifically, includes a first flat plate mount 71 and a second downward-tilting mount 9. When the mount, the mounting plate, and the bottom mount are mounted and fixed in a superimposed manner, the mount is fixed to the first plate portion 81 by a pin catch or a screw nut via a rubber foot pad, and the second downward inclined portion 82 is fixed to the second downward inclined mount 9 by a pin catch or a screw nut via a rubber foot pad.
The mounting system comprises two mounting structures, namely a mounting frame and a mounting plate, wherein the mounting frame and the mounting plate are arranged with the bottom fixing piece in a slanting and overlapping mode through rubber foot pads (namely, the mounting frame and the mounting plate are arranged at a certain angle with the gravity center direction of the compressor), so that a first layer of rubber foot pad is formed between the mounting frame and the mounting plate, a second layer of rubber foot pad is added between the mounting plate and the bottom fixing piece of the mobile refrigerator, and secondary vibration reduction is formed. The structure can improve the elasticity of the system, increase the damping of the system and realize the gradual attenuation of the vibration impact.
In a variation of the third embodiment of the mounting system, the mounting plate 8 may further adjust the number of through holes to adjust the number of secondary shock absorbing foot pads according to different shock absorbing requirements. For example, as shown in fig. 7, each second downward inclined portion 82 of the mounting plate may have three through holes for attaching rubber pads, respectively, so that the number of second-layer rubber pads may be increased to six. This further increases the system elasticity, allowing rapid damping of vibrations.
In addition or alternatively, three second downward-inclined portions or four second downward-inclined portions may be provided, respectively, in addition to one second downward-inclined portion 82 provided at each of the opposite edges, i.e., a total of two second downward-inclined portions.
Additionally or alternatively, in one implementation of the third embodiment of the mounting system 10, as shown in fig. 6 and 7, the condenser assembly 4 and the fan 5 may be disposed on the first plate portion 81 of the mounting plate 8. In this embodiment, the compressor 1, the condenser assembly 4 and the fan 5 are all arranged on the first plate portion 81, so that the refrigeration assembly formed by the compressor 1, the condenser assembly 4 and the fan 5 can be integrated on the mounting system 10, forming a modular refrigeration assembly. The assembly of the entire refrigeration assembly can be completed when the mounting system 10 is secured to the bottom fixture 7 of the mobile refrigerator. In addition, since the condenser assembly 4 and the fan 5 are disposed on the first flat plate portion 81, the additional second rubber pad fixing the mounting plate 8 to the bottom fixture 7 of the mobile refrigerator may also serve to attenuate vibration and impact to which the condenser assembly 4 and the fan 5 are subjected.
In the present invention, the mounting frame, the mounting plate and the bottom fixing member in any of the above embodiments are stacked and disposed to form an elastic connection through rubber pads, wherein fig. 8A and 8B and fig. 9A and 9B show two types of rubber pads 2 and 3, respectively, which can be used in the mounting system of the first aspect of the present invention. When one of the rubber foot pads 2 is used, the rubber foot pads are connected through pin shaft buckles. Specifically, as shown in fig. 8A and 8B (see fig. 8B in particular), the rubber is hollow inside, the pin 22 penetrates through the mounting plate, the rubber and the gasket 23, and the gasket, the rubber, the compressor and the mounting plate are pressed tightly by the L-shaped buckle 24; in addition, the pin 22 penetrates through the bottom fixing piece, the rubber and the gasket, the rubber, the mounting plate and the bottom fixing piece are pressed tightly through the L-shaped buckles, so that damping is generated through viscoelasticity of rubber materials and friction force generated by pressing, forced vibration borne by the compressor is relieved, and a secondary vibration damping structure is formed. When another rubber foot pad 3 is used, it is fixed by a screw and a nut. Specifically, as shown in fig. 9A and 9B (see fig. 9B in particular), the rubber may be a through hole inside and is equipped with a positioning thimble 32, a screw 34 passes through a gasket 33, the rubber, the positioning thimble and the mounting plate, and the compressor, the rubber and the mounting plate are fixed together by tightening a nut 35; in addition, the screw 34 passes through the gasket, the rubber, the positioning thimble and the bottom fixing piece, and then the mounting plate, the rubber and the bottom fixing piece are fixed together by screwing the nut 35, so that the elastic connection and the secondary vibration damping structure are formed.
Alternatively, in a fixedly attached embodiment, the rubber pads 2 and 3 described above may be used in combination. For example, the pad forming the first stage damping vibration-damping pad, which fixes the mounting frame to the mounting plate, may be the rubber pad 2, and the pad additionally forming the second stage damping vibration-damping pad, which fixes the mounting plate to the mobile refrigerator bottom fixture, may be the rubber pad 3, or vice versa.
Additionally or alternatively, in an embodiment of the mounting system according to the first aspect of the present invention, the number of mounting plates may be adjusted to form a multi-stage damped damping foot pad structure, i.e. a plurality (e.g. two, three, or even more) of mounting plates are formed by rubber foot pad lamination. Specifically, the installation frame passes through the callus on the sole installation to be fixed on first mounting panel, and first mounting panel is then fixed on next mounting panel through the callus on the sole installation, fixes on the bottom mounting of removing the refrigerator through the callus on the sole installation until last mounting panel. Therefore, a multistage damping vibration attenuation foot pad layer is formed, the system elasticity can be further effectively increased, the system vibration damping is adjusted, the vibration and the impact on the mobile refrigerator for the vehicle are gradually attenuated, the service life of the compressor is prolonged, and the NVH is reduced.
In an alternative embodiment of the mounting system (not shown) the mounting system comprises a mounting frame and a mounting plate, the mounting frame fixing the compressor to said mounting plate via foot pads, however, unlike the previous embodiments, the mounting plate is directly integrated in the bottom fixture of the mobile refrigerator, for example integrally formed with the bottom fixture or directly assembled and fixed to the bottom fixture when the refrigerator housing is prepared, so that the compressor is mounted and fixed in the mobile refrigerator. The mounting system configuration may be combined with any of the features of the embodiments described above, such as the structural features of the mounting frame, and/or the structural features of the mounting plate, etc.

An improved footpad in accordance with a second aspect of the present invention is described below with reference to the accompanying drawings. The foot pad is a multi-layer rubber foot pad.
Fig. 10 illustrates one embodiment of an improved footpad in accordance with a second aspect of the present invention. The foot pad 25 is a two-layer rubber foot pad comprising a relatively hard rubber layer and a relatively soft rubber layer. Specifically, the first layer 26 (i.e., the inner layer) is a harder rubber, while the second layer 27 (i.e., the outer layer) is a softer rubber. In addition, a recess 28 for cooperation with a through hole in the mounting system is provided in the upper part of the second layer 27. The foot pad is of a double-layer structure, wherein the soft rubber layer can absorb sub-synchronous resonance, and the hard rubber layer can bear and/or damp impact, even strong vibration impact.
In an alternative embodiment, a softer rubber may be used for the first layer 26 and a harder rubber for the second layer 27 in the two-layer rubber foot construction. Or, alternatively, the first layer 26 and the second layer 27 may both be made of rubber of the same material.
Additionally or alternatively, as shown in fig. 10, there is a flange 29 on top of the second layer 27 (i.e., the outer layer). Due to the presence of the flange, it is not necessary to use a washer as shown in fig. 8A and 8B and fig. 9A and 9B when making the connection by pin snapping and/or fixing by screw nut.
