Description

A kind of sunshade torque arm
Invention field
The present invention relates to a kind of torque arm, and in particular to a kind of sunshade torque arm belongs to vehicle material technical field.
Background technique
The automobile sun-shade curtain of the prior art is especially used for the electric driven sunshading curtain for car of luxury car, such as State Intellectual A kind of utility model patent of entitled motor vehicle rear curtain is disclosed on property right board web, and disclosed technical solution includes setting Guide rail and pedestal on vehicle window are provided with rotatable pipe crimping in pedestal, are connected with cord between guide rail and pipe crimping, on pedestal It is provided with driving device and connects a turntable in end, turntable connects a torque arm mechanism, and torque arm mechanism includes left and right with turntable The left and right torque arm that both ends pin shaft connects, torque arm mechanism connect a rocker arm body, and rocker arm body top is provided with sliding block, sliding block It is arranged in the sliding slot of guide rail, a protection pulley mechanism is respectively arranged in the left and right both ends of guide rail, and pipe crimping connects an edge of cord, separately One edge is connected with guide rail.The structure of rolling of the motor vehicle rear curtain is realized automatic, fast using torque arm and rocker arm linkage Curtain function is opened in victory, and the action process for opening and closing curtain is dexterous easy, and has protection pulley gear so that curtain with Glass for vehicle window has good Elastic Contact state in relative motion.But the structure of rolling of the window blind is being opened or is being closed When closing curtain movement, opening or closing for curtain is only carried out by the shake of the left rocker arm of rocker arm body and right rocker arm, therefore should The structural stability of the structure of rolling of window blind is poor, shaking is also easy to produce when opening or closing in curtain, operation stability is poor.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, high, excellent anti-corrosion performance screening that the invention proposes a kind of intensity Positive curtain torque arm.
The purpose of the present invention is realized by following technical solution: a kind of sunshade torque arm, the sunshade torque arm is by closing Golden Steel material is made, and the alloy steel material is by following mass percent at being grouped as: C:0.1-0.2%, Si: 0.8-1.1%, Mn:6.5-7.5%, Ni:5.5-6%, Cr:17.0-17.5%, N:0.2-0.3%, Mo:2.5-2.7%, P: ≤ 0.05%, it polymerize diamond nanoparticles stick: 0.3-0.5%, glassy metal: 1.2-1.5%, surplus Fe.
Glassy metal is added in sunshade torque arm of the present invention in alloy steel material, can enhance sunshade torque arm intensity, Corrosive nature, and using the high rigidity of polymerization diamond nanoparticles stick, sunshade torque arm intensity and hardness obtained can be made all excellent, To improve its service life.
The advantages of wherein glassy metal is also known as amorphous alloy, its existing metal and glass, and overcome their own Disadvantage.The intensity of glassy metal is higher than steel, and hardness is more than high hard tool steel, and has certain toughness and rigidity, glassy metal Atomic order be it is unordered, it does not have special weak link, therefore the Resisting fractre intensity of glassy metal is than common metal material Expect much higher, glassy metal does not have grain boundary as metal, and corrosive agent can be bored without gap, so fundamentally solving gold The etching problem for belonging to crystal boundary, is amenable to the corrosion of a variety of chemical solutions, there is good chemical stability.
In a kind of above-mentioned sunshade torque arm, the mass ratio of the Cr element and Mo element is (5-6): 1.Wherein chromium can be shown It writes and improves intensity, hardness and wearability, but reduce plasticity and toughness simultaneously.Chromium can improve the inoxidizability of steel and corrosion-resistant again Property, thus be stainless steel, the important alloying element of heat resisting steel.And molybdenum can make the crystal grain refinement of steel, improve harden ability and heat resistance Can, enough intensity and creep resisting ability are kept at high temperature.Molybdenum is added in structural steel, mechanical performance can be improved, can also press down Alloyage steel brittleness due to caused by fire.Ni is added in steel alloy, solution strengthening effect and harden ability can be improved, while thin Change ferrite crystal grain and improve the plasticity and toughness of steel, especially low-temperature flexibility in the identical situation of intensity, iron element can be strengthened Body simultaneously refines and increases pearlite, to improve the intensity of steel alloy.Meanwhile, it is capable to improve the fatigue resistance of steel, reduce alloy Sensibility of the steel to notch.
Preferably, mass percent of the polymerization diamond nanoparticles stick in stainless steel is 0.35-0.42%.Polymerization is bored Stone nanometer rods are that have the hardness harder than diamond and extremely high wearability in 2003 as made from the compression of graphite Can, also, unlike diamond, it can be produced on a large scale in industrial circle, therefore whether cost performance or feasibility, Mechanical performance for improving sunshade torque arm is all excellent selection.
It is another object of the present invention to provide a kind of preparation method of above-mentioned sunshade torque arm, the preparation method tool Body includes the following steps:
It is kneaded: pelletizing after weighing alloy steel material and binder mixing and injection molding must inject base；
