Description
Technical field
The pick-up unit of the present invention and a kind of engine component relates in particular to a kind of thermostat pick-up unit.
Background technology
Available engine thermostat parts have strict requirement to just opening temperature to performances such as the whole standard-sized sheet lift of standard-sized sheet temperature, thermostat sensitivity, hysteresis qualitys; But there is not relevant detection equipment to realize the thermostat Performance Detection; Therefore this problem becomes the problem of a big tackling key problem, and the performance of thermostat also is reflection controllable quality basis.This problem is not mainly owing to there are the relevant detection means to cause.Lack research technique and can not judge whether the performance of thermostat is qualified, so this problem fails to solve for a long time, give and produce and quality has been brought bigger adverse effect.
Chinese patent notification number CN1159020 has announced a kind of thermostat September 10 1997 day for announcing, and this thermostat comprises: the two ends that link to each other with outside line; With the fixed head that an end in the two ends links to each other, fixed contact is installed in above the fixed head; With the elastic plate that the other end in the two ends directly or indirectly links to each other, movable contact is installed in above the elastic plate, and movable contact is corresponding to fixed contact; The bimetallic plates of one end and elastic plate engagement; The connecting elements that jut is arranged; And fixed component; Thereby fixed head embeds connecting elements; All porose on elastic plate, bimetallic plates and the fixed component, the jut of connecting elements passes the hole of elastic plate, bimetallic plates and fixed head; The top of fusing jut, fixed component, bimetallic plates and elastic plate are fixed in the connecting elements; When the bimetallic plates temperature surpasses predetermined temperature; The crooked upset of bimetallic plates, the elastic plate distortion, movable contact separates with fixed contact; It is characterized in that: fixed component is folded to form by the sheet metal in the hole that two pairs of different-diameters are arranged; Every pair of hole is arranged in a straight line, and one is positioned at above another, and fixed component is according to a direction installation facing to bimetallic plates that has than the hole of minor diameter.The present invention seeks to adjust the firing rate of thermostat, and irrelevant, reduce the pollution of the thermostat that particle causes simultaneously with the elastic plate performance of thermostat.Fixed component is to be folded to form by sheet metal, and this sheet metal has at least one pair of hole of different-diameter, and the hole is arranged in a straight line each other.Fixed component has more wide-aperture part away from bimetallic plates, and the convexity of fixed head is passed fixed component, and the top of lug boss is melted and partly expanded than major diameter.
Chinese patent notification number CN1262384A has announced a kind of thermostat August 9 2000 day for announcing, can prevent the axle beat of piston, and permanance is good.Be configured in the coolant channels of internal combustion engine,, control the flowing of liquid coolant of said coolant channels, comprising: the valve body of tubular, stream zone, thermal valve door and branch road valve body according to the temperature variation of liquid coolant; Through making said branch road valve body with the motion of advancing and retreat of said piston; Said valve body opens and closes said inlet peristome and said exit opening portion; Thereby the said stream of connection/blocking zone, simultaneously, said valve body opens and closes said branch road peristome; And said branch road valve body switching station is stated the branch road path, thus said branch road peristome of connection/blocking and said branch road path.But above-mentioned thermostat has brought bigger adverse effect for production and quality because no thermostat pick-up unit can't detect the performance of thermostat.
