Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art with reference to explanation
Book word can be implemented according to this.
The utility model discloses a kind of expansion tank lid arrangements of the anti-scald in engine high-temperature；When engine occurs
During high temperature failure, ECU selects current direction and size of current by reading the temperature sensor signal being arranged in expansion tank
It is powered to electromagnet, so as to which electromagnet be made to attract each other with the push rod head with magnet；In addition, one can be generated in expansion tank
Constant-pressure, the square push rod head in the two comprehensive function lower header lid overcome initial tension of spring under gravitation and pressure effect
Compressed spring moves up；The toothed disc of push rod end is engaged with the gear ring being fixed on inside water tank, at this time expansion water tank cover without
Method rotarily opens；After water temperature reduction, ECU is by reading the temperature sensor signal being arranged in expansion tank, and selection is therewith
Preceding opposite current direction is powered to electromagnet, so as to mutually exclusive with the push rod head with magnet, and in cooling system
Portion's pressure reduction is moved down in initial tension of spring and repulsion effect lower push-rod, and gear disk detachment gear ring, tank lid can rotate
It opens and compensates and replace demand to meet daily coolant.
As shown in Figures 1 to 3, the utility model discloses a kind of expansion water tank cover of the anti-scald in engine high-temperature, water
100 shape of case lid shell is stepped cylinder, and upper cylindrical body is act as increasing when rotating tank lid and the frictional force of hand,
100 lower end of water tank cover housing is provided with the screw thread for being connect with swelling water babinet, and 100 top of water tank cover housing is equipped with through-hole
160, the square inside groove 120 connected with through-hole 160 is internally provided with, square 120 inner upper of inside groove places electromagnet 111b,
The electric wire of electromagnet can be connected to outside by through-hole；The position of electromagnet is fixed by ring spring 140；Electromagnet arranged beneath has
Cylindrical spring 150, spring arranged beneath transfer bar mechanism；Through-hole 160 ensures that pressure is atmospheric pressure above transfer bar mechanism upper surface；Just
Groove is opened up below square internal groove, for placing ring spring 140；Push rod is by ladder square head 110, square shape sealing ring
130th, upper surface magnet 111a and end gear 112a compositions, push rod head 110 is connect with end gear 112a by cylinder；It pushes away
Club head ensures to seal with rooved face in square by matching surface, while installs square shape sealing ring in push rod above-head
130 again ensure that sealing；Push rod head can electromagnet attract and repulsive force and pressure differential effect under in square inside groove on
Lower movement.
As shown in Fig. 3~Fig. 5, the utility model discloses a kind of expansion tank of the anti-scald in engine high-temperature, packets
The expansion water tank cover using the utility model is included, further includes temperature sensor 220 and ECU controllers；Temperature sensor 220 is installed
Below 210 inside the water tank, ECU controllers Electricity Federation temperature sensor 220 and electromagnet 111b, according to water the temperature inside the box to electromagnetism
Body is controlled.
The practical work process of anti-scald tank lid is specifically introduced with reference to two extreme positions above and below push rod.
As seen in figures 3-5, the course of work of the expansion tank of a kind of anti-scald in engine high-temperature of the utility model
It is as follows：
As shown in figure 3, set temperature threshold value is 50 DEG C, when water temperature is less than 50 DEG C, ECU readings are arranged in expansion tank
Temperature sensor 220 signal, judge that temperature is powered to electromagnet forward direction less than after 50 DEG C；Electromagnet generates after forward direction is powered
The magnetic pole identical with push rod Surface Magnet, the two is mutually exclusive, the trend that push rod generation moves downward, in addition, transfer bar mechanism is also
By the cylindrical spring elastic force and self gravitation effect compressed；Lower limit position is in three's collective effect lower push-rod, under
Extreme position is determined by the position of ring spring 140；When installing tank lid, adjusting tank lid angle first makes push rod end gear
112a passes through the gear ring 112b on water tank；Gear is not engaged with gear ring at this time and gear is below gear ring, rotates tank lid
Afterwards, tank lid is connected through a screw thread with water tank, and distance continues to increase between gear and gear ring, after screw thread screws, if expanding at this time
Coolant in water tank is normal temperature state, then entire expansion tank working condition is as shown in Figure 3.
As shown in Figure 4, Figure 5, when higher than 50 DEG C especially high temperature failure occurs for engine water temperature, coolant temperature raising
It even boils, 210 generate elevated pressures inside expansion tank, and pressure acts on push rod head undersurface 114, big with upper surface
Atmospheric pressure generates pressure difference, and push rod has the tendency that moving upwards under pressure；In addition, ECU readings are arranged in expansion tank
Temperature sensor 220 signal, judge temperature higher than being reversely powered to electromagnet after 50 DEG C, electromagnet generates after being reversely powered
The magnetic pole opposite with push rod Surface Magnet, the two attract each other, the trend that push rod generation moves upwards；It is total in atmospheric pressure and gravitation
Under same-action, push rod moves upwards until when being compressed to maximum compression deformation quantity of cylindrical spring 150, push rod reach limes superiors
Position, the gear 112a of end are engaged with gear ring 112b fixed on water tank, that is, reach the working condition such as Fig. 4, if at this time
Tank lid is rotated, push rod is since gear-wheel gear-ring engagement can not rotate, and tank lid enclosure square inside groove and push rod head
Cooperation, due to that for square structure, will not produce relative rotation therebetween；Therefore, in Fig. 4, tank lid
Entirety can not rotate namely tank lid can not be opened.
When liquid temperature to be cooled is reduced to less than 50 DEG C, 210 pressure are greatly reduced inside expansion tank, in repulsion, spring
Under elastic force and push rod self gravitation effect, push rod, which moves downward, arrives again at lower limit position, and gear is detached from gear ring at this time, rotation
Turn tank lid after screw thread is all unscrewed, gear is still below gear ring, i.e., gear ring will not interfere with the rotary motion of tank lid；This
When, adjustment tank lid angle makes push rod end gear 112a pass through the gear ring 112b on water tank, and tank lid can be opened integrally
Meet daily coolant compensation and replace demand.
When engine generates high temperature failure, most drivers can select switch-off, and ECU can not obtain temperature letter at this time
Breath, electromagnet power-off, at this point, device becomes purely mechanic control structure；If water temperature is higher, inside expansion tank 210 generate compared with
High pressure, pressure act on push rod head undersurface 114, generate pressure difference with the atmospheric pressure of upper surface, push rod is acted in pressure
Under move upwards, the gear 112a of push rod end can still be engaged with gear ring 112b fixed on water tank at this time, tank lid without
Method is opened.As temperature reduces, 210 pressure are greatly reduced inside expansion tank, in spring force and push rod self gravitation effect
Under, push rod, which moves downward, arrives again at lower limit position, and tank lid can be opened at this time, that is, can still play protection after shutting down drives
The effect of the person's of sailing safety.
Although the embodiment of the utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modification is easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
Specific details and legend shown and described herein are not limited to novel.
