In the description of the present invention, "a plurality" means two or more unless otherwise specified.
The prior art needs a support to support the fixing device, but the prior support structure can support the device, but the vibration of the device is easily transmitted to the adjacent device, so that the vibration value in the adjacent period is increased. The existing vibration damping structure usually utilizes the elastic deformation of an elastic component for vibration damping, for example, the elastic deformation of a compression spring is utilized for vibration damping, so that the vibration damping effect is good; however, the elastic member has a large amount of elastic deformation and poor stability when pressed, and thus it is difficult to provide a good supporting function. Therefore, the prior art structure often has difficulty in simultaneously achieving vibration isolation and supporting functions.
Example 1
In view of the above problems, the present embodiment provides a supporting type vibration damping structure, which includes an upper base 1, a lower base 2, and an elastic member located therebetween for damping vibration, as shown in fig. 1 to 3, wherein: the upper base 1 presents a first support end 111 for abutting against the lower base 2 after deformation of the elastic assembly and/or the lower base 2 presents a second support end 211 for abutting against the upper base 1 after deformation of the elastic assembly, so as to limit the amount of deformation of the elastic assembly.
Wherein, the upper base 1 is used for contacting with the vibrator, the lower base 2 is used for contacting with the support, and the vibrator and the support can be arranged in any adjacent mode of up-down or left-right arrangement.
The elastic member for reducing vibration may be a buffer member capable of elastically deforming, and in consideration of convenience in buffering external force, the elastic member is preferably a spring member.
In the supporting type vibration damping structure in the embodiment, the elastic component is arranged between the upper base 1 and the lower base 2, and when the upper base 1 is subjected to the pressure of a vibrating object, the elastic component generates elastic deformation to reduce vibration, so that the vibration damping effect is effectively realized; the deformation amount of the elastic component is limited by the structure that the first supporting end 111 is abutted against the lower base 2 or the second supporting end 211 is abutted against the upper base 1, so that the elastic component is prevented from being deformed too much and being difficult to support a vibrating object, and the vibrating object is prevented from overturning; the structure combines the vibration reduction with the stable supporting effect, reduces the vibration, simultaneously considers the stability of the structure, and can be used for supporting the vibrating object to reduce the transmission of the vibration.
Referring to fig. 1 to 3, in the present embodiment, the upper base 1 has the first supporting end 111, and the lower base 2 has the second supporting end 211.
In order to improve the supporting effect, as an alternative embodiment, the distance from the first supporting end 111 to the lower base 2 is equal to the distance from the second supporting end 211 to the upper base 1.
By the structure, the first supporting end 111 abuts against the lower base 2, and the second supporting end 211 can abut against the upper base 1, so that the structure is stable and the supporting effect is good.
In order to enhance the damping effect, as an alternative embodiment, referring to fig. 1-3, the elastic assembly comprises a first elastic portion 31 located between and connecting the first support end 111 and the second support end 211.

The first elastic portion 31 may be a compression spring.
When the upper base 1 moves in the direction of the lower base 2 by the pressure of the vibrating object, the first elastic portion 31 is elastically deformed by the first support end 111 and the second support end 211, and the force is cancelled to reduce the vibration.
The first elastic portion 31 functions as follows: one is to connect the first support end 111 and the second support end 211 (i.e., to connect the upper base 1 and the lower base 2); secondly, when the upper base 1 bears the vibrating object, the pressure is offset through elastic deformation, and vibration is reduced.
As an alternative embodiment, the elastic member includes a second elastic portion 32, and the second elastic portion 32 is located between the supporting surface of the upper base 1 for contacting the vibrator and the supporting surface of the lower base 2 for contacting the supporter. The second elastic portion 32 may also be a spring.
The supporting surface of the upper base 1 for contacting with the vibrator is a plane, and the supporting surface of the lower base 2 for contacting with the vibrator is a plane. In addition to the first elastic portion 31, when the upper base 1 receives a pressure of the vibrating object, the pressure is transmitted to the second elastic portion 32 in addition to the gravity of the upper base 1 itself, and the second elastic portion 32 is elastically deformed to act on an upward elastic force of the upper base 1, thereby canceling the force and reducing the vibration.
As an alternative embodiment, referring to fig. 1 and 2, the upper base 1 is connected to the lower end of the first elastic part 31, and the first supporting end 111 is lower than the bottom end of the first elastic part 31; the lower base 2 is connected to the upper end of the first elastic portion 31, and the second supporting end 211 is higher than the top end of the first elastic portion 31.
Referring to fig. 3, both the upper and lower bases may be connected to the corresponding ends of the first elastic portion 31 by the existing bolt assembly 9.

The structure of the lower support connection part 21 is the same.

The upper substrate 12 facilitates increasing a contact area between the upper base 1 and the vibrating object, the lower substrate 22 facilitates increasing a contact area between the lower base 2 and the supporting object, and the second elastic portion 32 is located therebetween to reduce vibration, thereby enhancing a supporting effect and a vibration reduction effect at the same time.
The first supporting end 111 and the second supporting end 211 limit the deformation amount of the elastic component, the deformation range of the elastic component can be specifically set according to actual conditions, as an alternative embodiment, as shown in fig. 1 and fig. 2, the first supporting end 111 is spaced from the lower substrate 22, and the second supporting end 211 is spaced from the upper substrate 12.
When the first supporting end 111 moves to contact with the lower substrate 22, the first elastic part 31 and the second elastic part 32 are not deformed. Preferably, the distance between the first supporting end 111 and the lower substrate 22 is equal to the distance between the second supporting end 211 and the upper base 1. Under the pressure of the vibrating object, the first supporting end 111 contacts with the lower substrate 22 and the second supporting end 211 contacts with the upper substrate 12 at the same time, so that the contact area is increased, and the stability of the supporting structure is improved.
In order to improve the stability of the support structure, as shown in fig. 1-3, a plurality of second elastic parts 32 are disposed between the upper substrate 12 and the lower substrate 22, and the plurality of second elastic parts 32 are disposed around the first elastic part 31, in order to form a stable support structure by the cooperation of the first support end 111 and the lower base 2 and the cooperation of the second support end 211 and the upper base 1.

In this embodiment, when the upper base 1 is pressed to move toward the lower base 2, the first elastic portion 31 is stretched, the second elastic portion 32 is compressed, and both elastic components raise an upward acting force toward the upper base 1 to counteract the pressing force. Meanwhile, when the first supporting end 111 abuts against the lower base 2 and the second supporting end 211 abuts against the upper base 1, the deformation of the first elastic part 31 and the second elastic part 32 is limited, and the stability of the supporting structure is ensured.
For the compactness of the structure and the stability of the structure, as an alternative embodiment, see fig. 2, the first elastic part 31 and the second elastic part 32 are equal in height in the vertical direction.
The elastic force provided by the first elastic part 31 in the middle and the second elastic part 32 in the periphery are equal, and the structural stability can be improved.
During specific work, the first elastic part 31 offsets pressure in the middle of the whole structure, the second elastic parts 32 offset pressure around the whole structure, in order to ensure that the forces received around and in the middle of the upper base 1 are equal, and the vibrating object is supported more stably, as an optional implementation mode, the number of the second elastic parts 32 is A, and the elastic coefficient K of each second elastic part 322All of them are equal, and the elastic coefficient K of the first elastic part 311Satisfy K1＝AK2。
