Description

Technical Field

[0001] This utility model relates to the field of viscous damper technology, specifically to an accelerated cooling viscous damper. Background Technology

[0002] A viscous damper is a cylinder-type structure filled with a damping medium. The reciprocating motion of a piston drives the flow of the internal medium, producing a damping effect and converting kinetic energy into heat energy. It is an energy-dissipating and shock-absorbing device. It mainly consists of a piston, cylinder, end caps, damping medium, and connecting parts. When the piston reciprocates within the cylinder, the damping medium flows rapidly between the two separated chambers. Intense friction occurs between the medium molecules and between the medium and the piston. The medium generates significant throttling damping as it passes through the piston orifice. The resultant force of these actions is called the damping force. The damping force generated during the flow converts the kinetic energy from earthquakes, wind-induced vibrations, etc., into heat through the reciprocating motion of the piston within the damping medium, gradually reducing the piston's speed and thus achieving the purpose of damping and energy dissipation.

[0003] For example, the utility model application with application number CN202323487577.3 provides a viscous damper. This application provides a first reset part at the piston rod and a reset assembly is assembled between the cylinder and the fixed part, so that the second reset part and the first reset part are movablely engaged. The force application part applies pressure to the first reset part and the second reset part together. When the external force is removed, the first reset part and the second reset part return to their initial positions. The force application part achieves directional guidance reset, thereby allowing the piston rod to fully reset, so that the viscous damper eliminates the residual deformation of the damped object after vibration. However, the existing viscous damper generates a certain amount of heat during operation. When the temperature rises, the damping characteristics will be affected, thus affecting the vibration reduction effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an accelerated cooling viscous damper. Utility Model Content

[0005] The purpose of this invention is to provide an accelerated cooling viscous damper to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an accelerated cooling viscous damper, comprising a cylinder and a cooling assembly, wherein a piston rod is provided inside the cylinder, and the cooling assembly for accelerated cooling is located outside the middle of the cylinder, and the cooling assembly includes a mounting box, an oil bladder, a movable plate, a heat sink, a spring, a fixing plate, and a limiting hole, wherein an oil bladder is provided inside the mounting box, and a movable plate is provided at the upper end of the oil bladder, a heat sink is installed at the upper end of the movable plate, and a spring is provided on the side of the heat sink, the upper end of the spring is connected to the fixing plate, and a limiting hole is provided on the surface of the fixing plate.

[0007] Furthermore, the diameter of the mounting box is the same as the diameter of the movable plate, and the movable plate and the heat sink are fixedly connected.

[0008] Furthermore, the heat sink and the spring are arranged in a ring at intervals, and the heat sink and the limiting hole are connected by a sleeve.

[0009] Furthermore, a connecting plate is connected to the end of the piston rod, and a rubber protective sleeve is provided on the outside of the end of the piston rod.

[0010] Furthermore, an auxiliary component for promoting airflow is provided above the heat sink, and the heat sink and the fixing plate are vertically distributed.

[0011] Furthermore, the auxiliary component includes an auxiliary cover and a blower hole, and the blower hole is provided on the surface of the auxiliary cover.

[0012] Furthermore, the auxiliary component also includes a delivery pipe and a main pipe, with the upper end of the blower hole connected to the delivery pipe and the end of the delivery pipe connected to the main pipe.

[0013] Furthermore, a hollow box is connected to the end of the main pipe, and a fan is installed inside the hollow box.

[0014] This invention provides an accelerated cooling viscous damper, which has the following beneficial effects:

[0015] 1. This utility model uses a system where the oil bladder and the cylinder are connected and both contain the same damping medium. When the piston rod retracts into the cylinder, the damping medium inside the cylinder acts as a buffer while being squeezed into the oil bladder. The damping medium in the oil bladder mixes with the damping medium in the oil bladder to transfer heat. The movable plate and heat sink quickly dissipate the heat to the outside air for accelerated heating, thus cooling the damper. After the oil bladder expands, it pushes the movable plate to compress the spring. When the piston rod extends out of the cylinder, the spring's rebound force pushes the movable plate, causing the cooled damping medium to return to the cylinder.

[0016] 2. This utility model uses a blower hole to deliver the flowing air output from the fan in the main pipe to the heat sink, further accelerating its heat dissipation effect. The auxiliary cover allows the flowing air to better act on the heat sink for heat dissipation. The hollow box is used for the installation of the fan and provides external protection for the fan.

Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 2As shown, an accelerated cooling viscous damper includes a cylinder 1 and a cooling assembly 3. A piston rod 2 is disposed inside the cylinder 1. The cooling assembly 3, used for accelerated cooling, is located outside the middle of the cylinder 1. The cooling assembly 3 includes a mounting box 301, an oil bladder 302, a movable plate 303, a heat sink 304, a spring 305, a fixed plate 306, and a limiting hole 307. The oil bladder 302 is disposed inside the mounting box 301. When the oil bladder 302 expands, it pushes the movable plate 303 to compress the spring 305. When the piston rod 2 extends out of the cylinder 1, the rebound force of the spring 305 pushes the movable plate 303, causing the cooled damping medium to return to the inside of the cylinder 1. The diameter of the mounting box 301 is the same as the diameter of the movable plate 303, and the movable plate 303 and the heat sink 304 are fixedly connected. The oil bladder 302 and the inside of the cylinder 1 are connected and both contain the same damping medium. When the piston rod 2 retracts into the inside of the cylinder 1, the damping medium inside the cylinder 1... The damping medium, while acting as a buffer, is squeezed into the oil bladder 302 and mixes with the damping medium in the oil bladder 302 to transfer heat. A movable plate 303 is provided at the upper end of the oil bladder 302. The movable plate 303 and the heat sink 304 quickly dissipate heat to the outside air for accelerated heating, thereby cooling and heat dissipating the damper. A heat sink 304 is installed at the upper end of the movable plate 303. The heat sink 304 and the spring 305 are distributed in a ring at intervals. The heat sink 304 and the limiting hole 307 are connected by a sleeve. A spring 305 is provided on the side of the heat sink 304. A fixing plate 306 is connected to the upper end of the spring 305. The fixing plate 306 is fixedly installed on the outside of the cylinder 1. A limiting hole 307 is opened on the surface of the fixing plate 306. The limiting hole 307 allows the heat sink 304 to move in a directional manner when it moves, increasing the stability of the movement. A connecting plate 4 is connected to the end of the piston rod 2, and a rubber protective sleeve 5 is provided on the outside of the end of the piston rod 2.

[0023] like Figure 3 As shown, an auxiliary component 6 for promoting airflow is provided above the heat sink 304, and the heat sink 304 and the fixing plate 306 are vertically distributed. The auxiliary component 6 includes an auxiliary cover 601 and a blower hole 602. The blower hole 602 is provided on the surface of the auxiliary cover 601. The auxiliary cover 601 allows the flowing air to better act on the heat sink 304 for heat dissipation. The auxiliary component 6 also includes a delivery pipe 603 and a main pipe 604. The upper end of the blower hole 602 is connected to the delivery pipe 603. The blower hole 602 delivers the flowing air output by the fan 8 in the main pipe 604 to the heat sink 304, further accelerating its heat dissipation effect. The end of the delivery pipe 603 is connected to the main pipe 604. The end of the main pipe 604 is connected to a hollow box 7. The hollow box 7 is used for the installation of the fan 8 and provides external protection for the fan 8. The fan 8 is installed inside the hollow box 7.

[0024] In summary, this accelerated cooling viscous damper is first based on... Figures 1-3The structure shown in the diagram allows the viscous damper to be installed in the required position via the connecting plate 4. When the viscous damper is working, as the piston rod 2 retracts into the cylinder 1, the damping medium inside the cylinder 1 acts as a buffer while being squeezed into the oil bladder 302. The damping medium in the oil bladder 302 mixes with the damping medium in the oil bladder 302 to transfer heat. The movable plate 303 and the heat sink 304 quickly dissipate the heat to the outside air for accelerated heating, thus cooling the damper. At this time, the oil bladder 302 expands and pushes the movable plate 303 to compress the spring 305. Then, when the piston rod 2 extends out of the cylinder 1, the rebound force of the spring 305 pushes the movable plate 303, causing the cooled damping medium to return to the inside of the cylinder 1. If the outside temperature is high, the fan 8 is turned on, and the blower 602 delivers the flowing air output from the fan 8 in the main pipe 604 to the heat sink 304, further accelerating its heat dissipation effect. The auxiliary cover 601 allows the flowing air to better act on the heat sink 304 for heat dissipation.
