For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.
[0036] like Figure 1 and Figure 2 The figure shows an embodiment of the vibration reduction structure provided by the present invention. The vibration reduction structure of this embodiment is used to install a vibration body 1 (such as a compressor) on a mounting surface 2 (such as the inner side of a device housing), and the vibration reduction structure is arranged between the vibration body 1 and the mounting surface 2, and the vibration reduction structure provides damping to achieve a vibration reduction effect.
[0037] The vibration reduction structure of this embodiment includes a plurality of groups of vibration reduction components 3, all of which are arranged on the outer surface of the vibration body 1 at intervals along the circumference of the vibration body 1, and each of the vibration reduction components 3 is connected to the mounting surface 2, so that the vibration body 1 is mounted on the mounting surface 2 by the plurality of groups of vibration reduction components 3, and a plurality of supporting points for supporting the vibration body 1 are formed along the circumference of the vibration body 1, so as to ensure the stability of the vibration body 1 after being mounted on the mounting surface 2. Preferably, all the vibration reduction components 3 are evenly distributed along the circumference of the vibration body 1 to ensure stable support for the vibration body 1. The number of vibration reduction components 3 is not limited, and a corresponding number of vibration reduction components 3 can be set according to the vibration condition of the vibration body 1, so that the overall vibration reduction capacity of the vibration reduction structure is adapted to the vibration reduction requirements. Preferably, at least three groups of vibration reduction components 3 are provided to form a more stable support in the circumference of the vibration body 1.
[0038] Each set of vibration reduction components 3 includes a base 31 and a damper 32. The base 31 is connected to the outer surface of the vibration body 1. The base 31 is preferably rigid, and the vibration reduction component 3 is mounted and fixed on the outer surface of the vibration body 1 through the base 31. One end of the damper 32 is connected to the base 31, and the other end of the damper 32 is used to connect to the mounting surface 2. The damper 32 provides damping to absorb the vibration of the vibration body 1 and play a vibration reduction role. The damper 32 is preferably made of an elastic material, and the elastic material used to make the damper 32 is preferably rubber. The interior of the damper 32 is axially penetrated to form a through hole, and the through hole is for a fastener to pass through. The fastener is used to connect and fix the base 31 to the mounting surface 2, so as to mount and fix the vibration body 1 to the mounting surface 2. The fastener is preferably a bolt. The axial direction of the damper 32 is at an angle to the axial direction of the vibration body 1, so that the radial and axial vibrations of the vibration body 1 can be transmitted to the damper 32, and the vibrations are absorbed by the damping and deformation of the damper 32, thereby effectively reducing the radial and axial vibrations of the vibration body 1 and achieving a better vibration reduction effect.
[0039] In this embodiment, preferably, the axes of the dampers 32 of all vibration-damping assemblies 3 intersect at the same intersection A, and the intersection A is located inside the vibration body 1, so that the vibration-damping assemblies 3 can effectively cooperate in the circumferential direction of the vibration body 1, thereby making the overall vibration-damping effect of the vibration-damping structure better.
[0040] Furthermore, in a preferred embodiment, the intersection A of the axes of the dampers 32 of all vibration reduction assemblies 3 is located on the first centroid axis L1, and the first centroid axis L1 is parallel to the axis of the vibrating body 1 and passes through the centroid of the vibrating body 1. In this way, the vibration reduction structure as a whole can play a better vibration reduction role on the vibration of the vibrating body 1, while taking into account the good support and limiting function of the vibrating body 1 to ensure the stability of the vibrating body 1. Among them, when the intersection A is located on the first centroid axis L1 close to the centroid of the vibrating body 1, the overall vibration reduction effect of the vibration reduction structure is better, and the support and limiting function is also better. Optimally, the intersection A coincides with the centroid of the vibrating body 1.
[0041] In another preferred embodiment, the intersection A of the axes of the dampers 32 of all vibration-damping assemblies 3 is located on the second centroid axis L2, and the second centroid axis L2 is parallel to the axis of the vibrating body 1 and passes through the centroid of the overall structure composed of the vibrating body 1 and all vibration-damping assemblies 3. In this way, the vibration-damping structure as a whole can play a better vibration-damping role on the vibration of the vibrating body 1, while taking into account the good support and limiting function of the vibrating body 1 to ensure the stability of the vibrating body 1. Among them, when the intersection A is located on the second centroid axis L2 close to the centroid of the overall structure composed of the vibrating body 1 and all vibration-damping assemblies 3, the overall vibration-damping effect of the vibration-damping structure is better, and the support and limiting function is also better. Optimally, the intersection A coincides with the centroid of the overall structure composed of the vibrating body 1 and all vibration-damping assemblies 3.
[0042] In practical applications, the first centroid axis L1 and the second centroid axis L2 may or may not coincide with each other.
[0043] In this embodiment, preferably, the base 31 has a mounting plate 311 connected to the damper 32, and the mounting plate 311 forms an angle with the axial direction of the vibrating body 1 and is perpendicular to the axial direction of the damper 32. The angle formed by the mounting plate 311 and the axial direction of the vibrating body 1 is α, and the angle formed by the axial direction of the damper 32 and the axial direction of the vibrating body 1 is β, and α and β are complementary angles.
[0044] Preferably, the base 31 also has a connecting plate 312, which is arranged on one end of the outer surface of the mounting plate 311 close to the vibration body 1. The connecting plate 312 is in contact with and fixedly connected to the outer surface of the vibration body 1. The connecting plate 312 and the mounting plate 311 form an angle, so that the axial angle of the mounting plate 311 relative to the vibration body 1 meets the requirements.
[0045] In this embodiment, preferably, a mounting hole 313 is provided on the mounting plate 311 and passes through the damper 32 axially, and an annular groove 321 is provided on the outer peripheral surface of the damper 32 in the circumferential direction. The damper 32 is connected to the mounting hole 313 through the annular groove 321, so that the damper 32 is passed through the mounting plate 311 of the base 31.
[0046] Regarding the connection mode between the damper 32 and the mounting surface 2, in a preferred embodiment, as follows Figure 1As shown, the mounting surface 2 is provided with an inclined assembly surface 21, and the inclined assembly surface 21 is parallel to the mounting plate 311 of the base 31, so as to facilitate the placement of the damper 32, and the end surface of the damper 32 used to connect one end of the mounting surface 2 is connected to the inclined assembly surface 21 provided on the mounting surface 2. The end surface of the damper 32 used to connect one end of the mounting surface 2 is placed on the inclined assembly surface 21, and the fastener passes through the through hole axially penetrating inside the damper 32 and is connected and fixed to the inclined assembly surface 21, so that the base 31 is connected and fixed to the inclined assembly surface 21, thereby installing and fixing the vibrator 1 to the inclined assembly surface 21 of the mounting surface 2.
[0047] In another preferred embodiment, Figure 2 As shown, a connection block 33 is provided at one end of the damper 32 for connecting to the mounting surface 2. The connection block 33 is rigid, and the end of the connection block 33 away from the damper 32 has a connection surface 331, and the connection surface 331 is adapted to the mounting surface 2. The end surface of the damper 32 for connecting to the mounting surface 2 is fitted on the connection block 33, and the fastener passes through the through hole axially penetrating inside the damper 32 and is connected and fixed to the connection block 33, so as to realize the connection and fixation between the base 31 and the connection block 33; the connection surface 331 of the connection block 33 is fitted and placed on the mounting surface 2 and connected and fixed by a connecting member (such as a screw or a bolt), thereby realizing the connection and fixation between the base 31 and the mounting surface 2, so as to install and fix the vibrating body 1 to the mounting surface 2. By adding a connection block 33 to adapt to the angle between the damper 32 and the mounting surface 2, it is convenient to connect the damper 32 with the mounting surface 2 which is generally flat, without the need to set an inclined assembly surface 21 on the mounting surface 2, and the assembly adaptability is better.

The compressor is used as the vibrating body 1, and the inner side surface of the housing of the temperature control device is used as the mounting surface 2.
