Description

Technical Field

[0001] This utility model relates to the technical field of dampers with variable damping force, and more particularly to dampers with variable damping force. Background Technology

[0002] A damper is a device that dissipates kinetic energy and slows down the vibration of an object by generating resistance. Its core function is to control the vibration amplitude and improve system stability. It is widely used in construction, transportation and other fields. Variable damping force dampers achieve precise vibration control by dynamically adjusting internal resistance. They are mainly divided into three categories: electromagnetic, magnetorheological, and hydraulic valve-controlled. Electromagnetic dampers adjust the electromagnetic field strength by changing the current, controlling the magnitude of the eddy current resistance generated by the conductor to achieve linear adjustment of the damping force. Magnetorheological dampers utilize the characteristic of drastic viscosity changes of magnetorheological fluids (oil-based liquids containing iron particles) under a magnetic field. Hydraulic dampers control the oil resistance by adjusting the valve opening to change the cross-sectional area of ​​the hydraulic oil flow.

[0003] Regarding the existing technology patent CN108799391B, which discloses a variable damping force unidirectional damper, including a top disc, piston rod, damper spring, damping cylinder, bottom disc, piston mechanism, and piston slide cavity, the design of the fixed ring sleeve, sliding ring sleeve, ring sleeve spring, and ring sleeve cover solves the influence of the piston rod sliding in the damping cylinder on the volume of the piston slide cavity in the damping cylinder. The piston rod spring identifies different downward pressures, causing the pressure bar to squeeze the adjusting block into the thin square tube by different amounts. The different amounts of the adjusting block entering the thin square tube result in different allowable flow speeds of hydraulic oil in the thin square tube. Ultimately, compared with the traditional unidirectional damper, the unidirectional damper of this invention can achieve the following effect: the faster the unidirectional damper is compressed, the greater the damping force of the unidirectional damper, and the slower the unidirectional damper recovers.

[0004] However, existing dampers with variable damping force are all installed by connecting parts at the front and rear ends. When vibration force is generated, the damper may vibrate and fall off due to the fixation at the front and rear ends, affecting its practicality and installation instability. To a certain extent, this has certain drawbacks and affects the working efficiency of the damper. Utility Model Content

[0009] Furthermore, the first connector includes a first insert rod, and a first spring is sleeved on the outside of the first insert rod. When the four second positioning blocks are engaged in the four second positioning slots, they are used for the synchronous compression of the first insert rod and the first spring, so that the first insert rod is inserted into the first socket.

[0010] Furthermore, the second connector includes a second insert rod, and a second spring is sleeved on the outside of the second insert rod. When the four first positioning blocks are engaged in the four first positioning slots, they are used for the synchronous compression of the second insert rod and the second spring, so that the second insert rod is inserted into the second socket.
