Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please refer to Figures 1 to 6 The present invention provides a vibration reduction structure for reducing vibration of a vibration source device 1. In order to connect the vibration source device 1 and the vibration reduction structure, the vibration source device 1 includes a fixing foot 2 with mounting holes.

[0028] To mitigate the vibration of the vibration source device 1, the vibration damping structure includes a rigid component 3, a first flexible component 4, and a second flexible component 5. The rigid component 3 is inserted into the first flexible component 4, which has a first insertion portion 41. The second flexible component 5 has a second insertion portion 51 that mates with the first insertion portion 41. The first insertion portion 41 and the second insertion portion 51 are interlocked, and the rigid component 3 is located inside the first insertion portion 41 and the second insertion portion 51. The mounting foot 2 is fitted onto the first insertion portion 41 or the second insertion portion 51 through a mounting hole.

[0029] This invention provides a vibration damping structure for damping vibrations of a vibration source device 1. The vibration source device 1 includes a fixed foot 2 with mounting holes. The vibration damping structure includes a rigid component 3, a first flexible component 4, and a second flexible component 5. The first flexible component 4 and the second flexible component 5 reduce the vibration of the vibration source device 1 in the vertical or horizontal direction. The rigid component 3 limits the compression of the first flexible component 4 and the second flexible component 5. This combined vibration damping structure satisfies multi-directional vibration damping. Furthermore, the specific structure facilitates matching the elasticity of the first flexible component 4 and the second flexible component 5, improving the vibration damping effect and thus solving the problem of poor vibration damping performance in existing vibration damping structures.

[0030] In the first embodiment:

[0031] like Figure 2 and Figure 3As shown, in order to facilitate the mutual insertion of the first insertion part 41 and the second insertion part 51, the first insertion part 41 is an insertion groove, and the first flexible component 4 includes a first main body part 43, which is arranged around the insertion groove; the second insertion part 51 is an insertion protrusion, and the second flexible component 5 includes a first limiting part 53, which is connected to the first limiting part 53.

[0032] Specifically, such as Figures 4 to 6 As shown, the first main body 43 has a cylindrical structure and the insertion groove has a cylindrical structure, so that the side of the first flexible component 4 near the opening of the insertion groove has a circular structure. This arrangement can reduce vibration while reducing the use of materials, reducing production costs, and reducing resource waste.

[0033] Furthermore, in order to fix the vibration source device 1 on the vibration damping structure, the mounting hole is fitted onto the second insertion part 51, and the inner wall of the mounting hole fits against the outer wall of the insertion protrusion, so that the mounting hole is in direct contact with the second flexible component 5, thereby reducing the vibration of the vibration source device 1 through the elastic action of the second flexible component 5, so as to reduce the vibration of the vibration source device 1 in the first direction.

[0034] Similarly, after the second connector 51 is inserted into the first connector 41, the two sides of the fixed foot 2 are respectively attached to the first flexible component 4 and the second flexible component 5, so that the first flexible component 4 and the second flexible component 5 fix the fixed foot 2 by clamping, thereby making the fixed foot 2 directly contact the first flexible component 4 and the second flexible component 5, and then the vibration of the vibration source device 1 is reduced by the elastic action of the first flexible component 4 and the second flexible component 5, so as to reduce the vibration of the vibration source device 1 in the second direction; wherein, the first direction is perpendicular to the second direction.

[0035] Specifically, the first direction is the horizontal direction, and the second direction is the vertical direction.

[0036] Generally, the second plug part 51 is interference-fitted with the first plug part 41. After the second plug part 51 is inserted into the first plug part 41, the elastic action of the first flexible member 4 and the second flexible member 5 prevents the second plug part 51 from coming out of the first plug part 41 during the operation of the vibration source device 1, thereby improving the vibration reduction effect.

[0037] Furthermore, in order to connect the rigid component 3 and the first flexible component 4, the first end of the rigid component 3 passes through the insertion groove and is inserted into the first flexible component 4, and the second end of the rigid component 3 protrudes out of the insertion groove, so that the rigid component 3 supports the first flexible component 4, thereby limiting the compression of the first flexible component 4; in order to connect the first flexible component 4 and the second flexible component 5, the second flexible component 5 has an installation opening 6. When the first insertion part 41 and the second insertion part 51 are inserted into each other, the second end of the rigid component 3 is inserted into the installation opening 6, so that the rigid component 3 supports the second flexible component 5, thereby limiting the compression of the second flexible component 5.

[0038] The outer wall of the rigid component 3 is in contact with the inner wall of the mounting opening 6.

[0039] Generally, such as Figure 2 and Figure 3 As shown, the fourth length dimension d of the second plug portion 51 is greater than the third length dimension c of the rigid member 3 protruding from the first plug portion 41, so that the second plug portion 51 can be inserted into the first plug portion 41 and prevent the second plug portion 51 from disengaging from the first plug portion 41.

[0040] Furthermore, in order to ensure that after the first insertion part 41 and the second insertion part 51 are inserted into each other, the two sides of the fixing foot 2 sleeved on the second insertion part 51 are respectively attached to the first flexible component 4 and the second flexible component 5, the fourth length dimension d of the second insertion part 51 is less than or equal to the sum of the third length dimension c of the rigid component 3 protruding from the first insertion part 41 and the second length dimension b of the first insertion part 41.

[0041] Preferably, in order for the rigid member 3 to support the first flexible member 4 and the second flexible member 5, the length dimension of the rigid member 3 is greater than or equal to the sum of the first length dimension a, the second length dimension b of the first insertion part 41 and the fourth length dimension d of the second insertion part 51.

[0042] Wherein, the first length dimension a is the difference between the length dimension of the first main body part 43 and the second length dimension b of the first insertion part 41.

[0043] Optionally, the third length dimension c of the rigid component 3 protruding from the first insertion part 41 is equal to the thickness of the fixed foot 2, so that when the fixed foot 2 is sleeved on the second insertion part 51, after the first insertion part 41 and the second insertion part 51 are inserted into each other, the two sides of the fixed foot 2 are respectively attached to the first flexible component 4 and the second flexible component 5, thereby clamping the fixed foot 2 with the first flexible component 4 and the second flexible component 5, thereby improving the vibration reduction effect.

[0044] Optionally, the first flexible component 4 and the rigid component 3 are integrally cast, so that the rigid component 3 is embedded inside the first flexible component 4, preventing the rigid component 3 from detaching from the first flexible component 4 during the operation of the vibration source device 1, thereby improving the vibration reduction effect.

[0045] In this embodiment, the rigid component 3 is fixedly connected to the first flexible component 4 with a insertion groove, which facilitates the connection between the first flexible component 4 and the rigid component 3, and the compression amount of the first flexible component 4 is limited by the rigid component 3.

[0046] In the second embodiment:

[0047] To facilitate the interlocking of the first insertion part 41 and the second insertion part 51, the first insertion part 41 is an insertion protrusion, and the first flexible component 4 includes a second limiting part, with the insertion protrusion connected to the second limiting part; the second insertion part 51 is an insertion groove, and the second flexible component 5 includes a second main body, which is arranged around the insertion groove.

[0048] Specifically, the second main body is a cylindrical structure, and the insertion groove is a cylindrical structure, so that the side of the second flexible component 5 near the opening of the insertion groove is a ring structure. This arrangement not only reduces vibration but also reduces material usage, production costs, and resource waste.

[0049] Furthermore, in order to fix the vibration source device 1 on the vibration damping structure, the mounting hole is fitted onto the first insertion part 41, and the inner wall of the mounting hole fits against the outer wall of the insertion protrusion, so that the mounting hole is in direct contact with the first flexible component 4, thereby reducing the vibration of the vibration source device 1 through the elastic effect of the first flexible component 4, so as to reduce the vibration of the vibration source device 1 in the first direction.

[0050] Similarly, after the first insertion part 41 is inserted into the second insertion part 51, the two sides of the fixed foot 2 are respectively attached to the first flexible component 4 and the second flexible component 5, so that the first flexible component 4 and the second flexible component 5 fix the fixed foot 2 by clamping, thereby making the fixed foot 2 directly contact the first flexible component 4 and the second flexible component 5, and then the vibration of the vibration source device 1 is reduced by the elastic action of the first flexible component 4 and the second flexible component 5, so as to reduce the vibration of the vibration source device 1 in the second direction; wherein, the first direction is perpendicular to the second direction.

[0051] Specifically, the first direction is the horizontal direction, and the second direction is the vertical direction.

[0052] Generally, the first plug-in part 41 and the second plug-in part 51 are interference-fitted. After the first plug-in part 41 is inserted into the second plug-in part 51, the elastic action of the first flexible member 4 and the second flexible member 5 prevents the first plug-in part 41 from coming out of the second plug-in part 51 during the operation of the vibration source device 1, thereby improving the vibration reduction effect.

[0053] Furthermore, in order to connect the rigid component 3 and the first flexible component 4, the first end of the rigid component 3 is inserted into the first flexible component 4, and the second end of the rigid component 3 protrudes from the insertion protrusion, so that the rigid component 3 supports the first flexible component 4, thereby limiting the compression of the first flexible component 4; in order to connect the first flexible component 4 and the second flexible component 5, the second flexible component 5 is provided with an installation opening 6 communicating with the insertion groove. When the first insertion part 41 and the second insertion part 51 are inserted into each other, the second end of the rigid component 3 passes through the insertion groove and is inserted into the installation opening 6, so that the rigid component 3 supports the second flexible component 5, thereby limiting the compression of the second flexible component 5.

[0054] The outer wall of the rigid component 3 is in contact with the inner wall of the mounting opening 6.

[0055] Generally, the length of the second plug portion 51 is greater than the length of the rigid member 3 protruding from the first plug portion 41, so that the first plug portion 41 can be inserted into the second plug portion 51 and prevent the first plug portion 41 from disengaging from the second plug portion 51.

[0056] Furthermore, in order to ensure that after the first insertion part 41 and the second insertion part 51 are inserted into each other, the two sides of the fixing foot 2 sleeved on the first insertion part 41 are respectively attached to the first flexible component 4 and the second flexible component 5, the length of the first insertion part 41 is less than or equal to the sum of the length of the rigid component 3 protruding from the second insertion part 51 and the length of the second insertion part 51.

[0057] Preferably, in order for the rigid member 3 to support the first flexible member 4 and the second flexible member 5, the length of the rigid member 3 is greater than or equal to the sum of the length of the second limiting part, the length of the second insertion part 51 and the length of the first insertion part 41.

[0058] Optionally, the length of the rigid component 3 protruding from the first insertion part 41 is equal to the thickness of the fixed foot 2, so that when the fixed foot 2 is sleeved on the first insertion part 41, after the first insertion part 41 and the second insertion part 51 are inserted into each other, the two sides of the fixed foot 2 are respectively attached to the first flexible component 4 and the second flexible component 5, thereby clamping the fixed foot 2 with the first flexible component 4 and the second flexible component 5, thereby improving the vibration reduction effect.

[0059] Optionally, the first flexible component 4 and the rigid component 3 are integrally cast, so that the rigid component 3 is embedded inside the first flexible component 4, preventing the rigid component 3 from detaching from the first flexible component 4 during the operation of the vibration source device 1, thereby improving the vibration reduction effect.

[0060] In this embodiment, the rigid component 3 is fixedly connected to the first flexible component 4 with the insertion protrusion, which facilitates the connection between the first flexible component 4 and the rigid component 3, and limits the compression amount of the first flexible component 4 by the rigid component 3.

[0061] Specifically, such as Figures 3 to 6 As shown, the rigid component 3 is a hollow structure with a hollow cavity 31; the first flexible component 4 has a first fixing hole 42, and the second flexible component 5 has a second fixing hole 52 corresponding to the first fixing hole 42; wherein at least a portion of the first fixing hole 42 is located inside the hollow cavity 31, and / or at least a portion of the second fixing hole 52 is located inside the hollow cavity 31, so as to connect the first flexible component 4 and the second flexible component 5 through the connecting assembly 8 passing through the first fixing hole 42, the hollow cavity 31 and the second fixing hole 52.

[0062] Optionally, the rigid component 3 is a metal steel pipe. The inner and outer sides of the rigid component 3 are in contact with a portion of the flexible body of the first flexible component 4 to prevent the fixed foot 2 from directly contacting the rigid component 3, thereby improving the vibration reduction effect while allowing the rigid component 3 to play a limiting role.

[0063] Preferably, the first flexible component 4 is made of rubber; the second flexible component 5 is made of rubber.

[0065] The air conditioner in this embodiment also includes a mounting plate 7, which has a third fixing hole for fixing the vibration source device 1 onto the mounting plate 7 by passing through the third fixing hole, the vibration damping structure, and the connecting assembly 8 that fixes the foot 2 in sequence.

[0066] Specifically, in order to fix the vibration source device 1 on the mounting plate 7, there are multiple fixing feet 2 and multiple vibration damping structures. The multiple vibration damping structures are set one-to-one with the multiple fixing feet 2 to prevent the vibration source device 1 from detaching from the mounting plate 7 during operation, and also to play a role in force balance.

[0067] Specifically, such as Figure 1 As shown, the connecting component 8 includes a connector 81 and a fastener 82.

[0068] Preferably, the connector 81 is a bolt and the fastener 82 is a nut.
