[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0030] like Figure 1-Figure 5 As shown, the utility model provides a nonlinear inertia viscous damper, including a cylinder body 1, a telescopic cover 2 is installed at one end of the cylinder body 1, a first connecting component 3 is installed on the surface of the telescopic cover 2, a second connecting component 4 is installed at the other end of the cylinder body 1, and a heat dissipation device 5 is provided on the arc surface of the cylinder body 1.
[0031] The specific configuration and function of the heat dissipation device 5 will be described in detail below.
[0032] like Figure 2-Figure 5As shown, the heat dissipation device 5 includes two fixing plates 501, both of which are fixedly connected to the cylinder body 1, and a plurality of connection holes 502 are opened on the surface of the fixing plate 501, and a plurality of screw rods 503 are threadedly connected to the surface of the fixing plate 501, and the arc surfaces of the plurality of screw rods 503 are threadedly connected to two clamping plates 504, and both of the clamping plates 504 are clamped with the connection holes 502, and a base 505 is fixedly connected to the surface of the base 505, and a fin 506 is fixedly connected to the surface of the fin 506, and the arc surface of the fin 506 is fixedly connected to the heat conducting plate 507. The heat conducting sheet 507 is fixedly connected to the base 505. The size of the heat conducting sheet 507 is adapted to the size of the cylinder 1. The heat conducting sheet 507 is a flexible graphite sheet. When the cylinder 1 is working, the heat generated will be transferred to the heat conducting sheet 507 through the cylinder 1. At this time, the heat conducting sheet 507, which is a flexible graphite sheet, can quickly absorb the heat on the cylinder 1. The fins 506 are aluminum sheets. The heat conducting sheet 507 will transfer the heat absorbed by itself to the fins 506. At this time, the fins 506, which are aluminum sheets, can quickly dissipate heat. The surface of the fins 506 is provided with a plurality of heat dissipation grooves 508, and the plurality of heat dissipation grooves 508 are evenly distributed. Distributed on the surface of the fin 506, the fin 506 will conduct part of the heat through the heat dissipation slot 508. At this time, the heat dissipation slot 508 can improve the heat dissipation efficiency of the fin 506. The surface of the screw rod 503 is fixedly connected with an anti-skid pad 509. The anti-skid pad 509 is a rubber pad. The screw rod 503 will drive the anti-skid pad 509 to move in the same direction. At this time, the rubber anti-skid pad 509 can abut against the fixed plate 501 while increasing the friction between the contact surface of the screw rod 503 and the fixed plate 501. One end of the screw rod 503 is fixedly connected with an elastic rope 510. The elastic rope 510 is fixed to the fixed plate 501. When the screw rod 503 is connected, the screw rod 503 will drive one end of the elastic rope 510 to move. At this time, the elastic rope 510 can prevent the screw rod 503 from being lost after being separated from the fixing plate 501 when the screw rod 503 is disassembled. The other end of the screw rod 503 is fixedly connected to a sharp cone 511. The sharp cone 511 is a stainless steel cone. When the screw rod 503 is rotated, the screw rod 503 will use its own thread to drive the sharp cone 511 into the fixing plate 501 and pass through the two clamping plates 504 clamped in the connecting hole 502. At this time, the sharp cone 511 can facilitate the screw rod 503 to enter the fixing plate 501 and pass through the two clamping plates 504 clamped in the connecting hole 502.
[0033] The overall working principle is that when it is necessary to install the heat dissipation fins 506 on the cylinder body 1, first, the clamping plates 504 on the two bases 505 are clamped into the connecting holes 502 opened on the fixed plate 501, and then the screw rod 503 is rotated. At the same time, the screw rod 503 will use its own thread to drive the pointed cone 511 to enter the fixed plate 501 and pass through the two clamping plates 504 clamped in the connecting holes 502. At this time, the pointed cone 511 can facilitate the screw rod 503 to enter the fixed plate 501 and pass through the two clamping plates 504 clamped in the connecting holes 502. The plate 504 is moved, and at the same time, the screw rod 503 drives one end of the elastic rope 510 to move. At this time, the elastic rope 510 can prevent the screw rod 503 from being lost after being separated from the fixed plate 501 when the screw rod 503 is disassembled. Then the screw rod 503 drives the anti-skid pad 509 to move in the same direction. At this time, the anti-skid pad 509 made of rubber can abut against the fixed plate 501 and increase the friction between the contact surface of the screw rod 503 and the fixed plate 501. Then, when the cylinder body 1 is working, the heat generated The heat is then transferred to the heat conducting sheet 507, which is a flexible graphite sheet and can quickly absorb the heat on the cylinder body 1. The heat conducting sheet 507 then transfers the absorbed heat to the fins 506, which are aluminum sheets and can quickly dissipate the heat. At the same time, the fins 506 will conduct part of the heat through the heat dissipation grooves 508. At this time, the heat dissipation grooves 508 can improve the heat dissipation efficiency of the fins 506. By providing the heat dissipation device 5, the cooperation among the fixing plate 501, the connecting hole 502, the screw rod 503, the clamping plate 504, the base 505, the fins 506 and the heat conducting sheet 507 can be used to quickly diffuse the heat generated inside the cylinder body 1, thereby avoiding the viscous damper from being significantly affected by temperature in actual use environment. The viscosity of the viscous fluid is related to temperature. When the temperature changes, the damping coefficient of the damper will change, resulting in unstable shock absorption performance when used in different seasons or different geographical areas. This improves the heat dissipation efficiency of the viscous damper and further improves the shock absorption performance of the viscous damper.
