[0002] The viscous damper is a velocity-type damper made using the principle of fluid motion.

With the development and progress of science and technology, the viscous damper has developed from a single-function fluid viscous damper to a shock-absorbing device with specific functions.

[0003] The energy dissipation mechanism of the viscous damper relies on the interaction within the structure, mainly including the interaction between the damping medium and the piston and the interaction between the damping medium and the cylinder body; during use, the damping medium is often greatly affected by temperature. In a continuous low-temperature environment, the viscosity of the damping medium will increase significantly, reducing the energy dissipation capacity of the viscous damper, resulting in a decrease in dynamic performance and a slower response speed during use. In the prior art, there are viscous dampers that use cooling components, but only consider the overheating and explosion caused by energy absorption and temperature rise during use, ignoring the impact of ultra-low temperature environments on viscous dampers, lacking adaptability to local conditions, resulting in insufficient performance of viscous dampers at low temperatures, affecting the safety of use in low-temperature environments.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-Figure 4 As shown, this embodiment provides an electromagnetic thermal insulation viscous damper, comprising:

[0031] Cylinder 1, the cylinder 1 is filled with damping medium 11;

[0032] An energy dissipation component, one end of which is arranged in the inner cavity of the cylinder body 1, the energy dissipation component is immersed in the damping medium 11 and reciprocates in the inner cavity of the cylinder body 1, and the other end of the energy dissipation component extends out of the cylinder body 1;

[0033] A heating component, the heating component includes an electromagnetic coil 7 which is arranged on the inner surface of the cylinder body 1, and an energy dissipation component which is surrounded by the electromagnetic coil 7;

[0034] The control component is arranged at the bottom end of the cylinder body 1 . The control component is electrically connected to the electromagnetic coil 7 . The control component detects the temperature of the damping medium 11 and controls the electromagnetic coil 7 to heat the damping medium 11 .

[0035] The present invention discloses an electromagnetic heat-insulating viscous damper. An energy dissipation component is immersed in a damping medium 11 in a cylinder body 1. When subjected to external impact, one end of the energy dissipation component located in the cylinder body 1 moves in the damping medium 11, so that a damping force is generated between the damping medium 11 and the energy dissipation component, and the kinetic energy of the energy dissipation component is converted into heat and dissipated, so that the movement speed of the energy dissipation component is gradually reduced, thereby achieving the purpose of damping energy consumption; a control component is arranged at the bottom end of the cylinder body 1, and is used to detect the temperature of the surrounding environment. When it is detected that the temperature is too low, the control component controls the electromagnetic coil 7 of the heating component to start, heats the damping medium 11 surrounded by the electromagnetic coil 7, increases the temperature of the damping medium 11, reduces the viscosity of the damping medium 11, and enables the damping medium 11 to maintain good mechanical properties in low-temperature cold areas, thereby greatly improving the response speed of the viscous damper in low temperatures. The present invention has a simple and compact structure and is easy to use. It can automatically detect the temperature of the surrounding environment when in use, heat the damping medium 11 at low temperatures, so that the damping medium 11 maintains good mechanical properties in low-temperature cold areas, thereby improving the use effect when used in high-cold areas.

[0036] In one embodiment of the present application, a heating chamber is opened in the cylinder wall of the cylinder body 1, and the electromagnetic coil 7 is embedded in the heating chamber, which is convenient for heating the damping medium 11 in the inner cavity of the cylinder body 1, and can effectively avoid the influence caused by the contact between the damping medium 11 and the electromagnetic coil 7.

[0037] In an extended embodiment of the present application, the heating chamber is filled with a high thermal conductivity fluid made of a high thermal conductivity material, and the high thermal conductivity fluid immerses the electromagnetic coil 7 , thereby increasing the heat transfer of the electromagnetic coil 7 to the damping medium 11 .

[0038] In one embodiment of the present application, when the damping medium 11 absorbs a large amount of kinetic energy and converts it into thermal energy, the temperature rises and the viscosity of the damping medium 11 decreases, which in turn causes the damping force of the damping medium 11 to decrease and the energy dissipation capacity to weaken, which will affect the safety of the viscous damper. Therefore, the high thermal conductivity fluid added in the extended implementation manner can also increase the heat dissipation efficiency of the damping medium 11 and improve the safety of the viscous damper.

[0039] In an extended embodiment of the present application, a sealing ring for sealing the heating chamber is provided at the bottom end of the heating chamber to seal the high thermal conductivity fluid in the heating chamber; the wire ends at both ends of the electromagnetic coil 7 pass through the sealing ring.

[0040] Further optimization scheme, the energy dissipation component includes a piston 3 slidably connected to the inner cavity of the cylinder body 1, and the piston 3 is immersed in the damping medium 11; the piston 3 is fixedly connected with a piston rod 2, which extends through the cylinder body 1 and is slidably connected to the cylinder body 1. The piston 3 is a cylindrical plate-like structure, and its edge slides with the inner cavity of the cylinder body 1 to limit the piston 3 and prevent the piston 3 from shaking; the damping medium 11 immerses the piston 3, dividing the inner cavity of the cylinder body 1 into two spaces, the upper and lower spaces, the piston rod 2 passes through the piston 3, and its top end extends out of the cylinder body 1 and is connected to the component that needs shock absorption; when the piston rod 2 is impacted, the piston rod 2 drives the piston 3 to move in the damping medium 11, converts the impact force received by the piston rod 2 into the internal energy in the damping medium 11 and the damping force between the damping medium 11 and the piston 3, and absorbs the impact force received.

[0041] In one embodiment of the present application, the damping medium 11 includes but is not limited to silicone oil and hydraulic oil. Those skilled in the art can select the corresponding damping medium 11 according to specific needs and usage environment, which will not be described in detail here.

[0042] In one embodiment of the present application, the damping medium 11 can also play a lubricating role, lubricating the inside of the cylinder 1 and the outer ring of the piston 3, reducing the friction between the piston 3 and the cylinder 1, reducing wear and tear, and extending the service life.

[0043] Further optimization scheme, a plurality of throttle holes 5 are provided through the piston 3, and the damping medium 11 flows between the two sides of the piston 3 through the plurality of throttle holes 5. A plurality of throttle holes 5 are provided through the piston 3, connecting the spaces at the upper and lower ends of the piston 3 in the cylinder body 1. When the piston 3 is impacted, the piston 3 is forced to move in the damping medium 11, so that the spaces at the two sides of the piston 3 change, and the damping medium 11 flows through the throttle holes 5. When the damping medium 11 passes through the small holes or gaps on the piston 3, it will generate huge throttling damping to absorb the impact on the piston 3.

[0044] Further optimization scheme, the two ends of the cylinder body 1 are respectively sealed with end covers 4, and the piston rod 2 passes through the end covers 4 and slides with the piston rod 2 in a sealed manner. The cylinder body 1 of the present application is a tube body that passes through the top and bottom, and the end covers 4 are arranged at both ends of the tube body to seal the tube body. The piston rod 2 passes through the cylinder body 1, and its two ends pass through the end covers 4 at the upper and lower ends. The piston rod 2 is limited by the end covers 4 to improve the stability of the energy dissipation component; the sealing arrangement between the end cover 4 and the piston rod 2 can effectively prevent the leakage of the damping medium 11.

[0045] Further optimization scheme, the bottom end of the cylinder 1 is provided with a connector 6, the bottom piston rod 2 passes through the bottom end cover 4 and extends into the cavity of the connector 6; the bottom end of the connector 6 is hinged with an embedded part, and the embedded part is hinged at the installation position. The connector 6 is a tubular structure, the top end of which is fixed to the bottom end of the cylinder 1 by bolts and abuts against the bottom end cover 4, and the end of the piston rod 2 extending out of the bottom end cover 4 is retracted in the connector 6; the bottom end of the connector 6 is connected to an end block, and the end block is hinged with the embedded part embedded in the location where shock absorption is required, and the viscous damper is installed at the corresponding position.

[0046] Further optimization scheme, the control component includes an electromagnetic heating controller 10 arranged in the inner cavity of the connector 6, the electromagnetic coil 7 is electrically connected to the electromagnetic heating controller 10, and the electromagnetic heating controller 10 is electrically connected to a temperature sensor 9, and the temperature sensor 9 measures the temperature of the surrounding environment. The electromagnetic heating controller 10 of the control component is fixedly installed in the connector 6, which is convenient for protecting the electromagnetic heating controller 10 through the connector 6; the electromagnetic heating controller 10 is electrically connected to the temperature sensor 9, and the temperature sensor 9 can detect the temperature of the surrounding environment and transmit the detected temperature data to the electromagnetic heating controller 10. When the temperature is detected to be too low, the electromagnetic heating controller 10 sends a control signal to the electromagnetic coil 7 to control the electromagnetic coil 7 to be powered on and start, and selects corresponding parameters according to the detected temperature data to heat the damping medium 11.

[0047] Further optimization scheme, a total of several wiring holes 8 are provided on the electromagnetic heating controller 10, and the two ends of the electromagnetic coil 7 pass through the end cover 4 at the bottom and are electrically connected to the electromagnetic heating controller 10 through the wiring holes 8. The wiring holes 8 on the electromagnetic heating controller 10 are used for the passage of connecting cables. The two ends of the electromagnetic coil 7 are sealed through the end cover 4 and then connected to the inside of the electromagnetic heating controller 10 through the wiring holes 8, which is convenient for data exchange.

[0048] Further optimizing the scheme, the electromagnetic heating controller 10 includes an electrically connected control unit and a power supply unit, and the control unit controls the heating power and working time of the electromagnetic coil 7. The electromagnetic heating controller 10 includes a protective shell fixed to the inner cavity of the connector 6, an electrically connected control unit and a power supply unit, the power supply unit is used to power the device to maintain the operation of the electrical components of the viscous damper of the present application; and the control unit serves as the control core of the present application to control the operation of each component.

[0049] In one embodiment of the present application, the power supply unit may be a battery with a charging function, so as to facilitate the use of the device at a predetermined location.

[0050] In one embodiment of the present application, the control unit selects a PLC with programming function, and can set operating parameters according to usage requirements and the properties of the damping medium 11. After detecting that the external ambient temperature is lower than the set value, the control unit controls the electromagnetic coil 7 to start heating the damping medium 11.

[0051] In a further optimized solution, the electromagnetic heating controller 10 includes a protection unit electrically connected to the control unit, and the protection unit stops working when it detects an abnormality in the electromagnetic heating controller 10.
