Abstract

The utility model discloses a vehicle shutter controller; more specifically, by utilizing the material characteristics of memory alloy, the vehicle shutter controller is made to a heat expansion and cold contraction type spring piece. By the action of a control rod, the opening angle of shutter blades can be automatically regulated according to the ambient temperature at the back of a water tank, and the cooling air quantity flowing through a shutter can be changed. The utility model overcomes the defect that the present vehicle shutter manually regulated has the randomness and can enable the cooling water temperature to be kept at the optimum temperature.

Description

Vehicle shutter controller

The utility model relates to a kind of automobile-used louver control setup, specifically utilizes the characteristic of memory alloy material to realize controlling louver opening angle size.

Automobile is in operational process, because the influence of factors such as load, speed, temperature, road conditions, the heat radiation amount of cooling water of driving engine needs in order to keep normal operation is different, louver is exactly one of device of regulating amount of cooling water, the blade of louver window opening angle increases, then increase cooling air quantity, otherwise reduced cooling air quantity.The size of existing automobile blade of louver window opening angle is by the height of chaufeur according to the cooling water temperature gauge indicated value in the operator's compartment, manual regulation louver handle is realized frequently, operation has very big artificial randomness, can not make cooling water expansion tank remain on optimum temperature range.

The purpose of this utility model be to propose a kind of can be according to the control setup of water tank rear portion ambient temperature automatically regulating blade of louver window opening angle size, reduce the artificial unfavorable factor of being brought of regulating.

Feature of the present utility model such as principle automobile-used louver control setup shown in Figure 1 is made up of memory alloy spring 1, control stalk 2, biasing steel spring 3 and tumbler 4, pulley 5, its memory alloy spring 1 is sleeved on the control stalk 2, and support by car body, pulley 5 and tumbler 4 are separately fixed on the car body, stay cord 6 one ends are connected with blade of louver window, the other end is fixed on the tumbler 4 by pulley 5, one end of biasing steel spring 3 joins through tumbler 4 and control stalk 2 lower ends, and the other end then is fixed on the car body.

Memory alloy spring 1 and biasing steel spring 3 are placed water tank 7 rear portions, link together by tumbler 4, pulley 5 and blade of louver window, memory alloy spring 1 is processed into heat expansion (shrinkage) formula, so just can be according to water tank rear portion ambient temperature automatically regulating blade of louver window opening angle size with the flow through cooling air 9 of louver of change.Concrete working process is: cooling water temperature is too high in water tank 7, the ambient temperature at water tank 7 rear portions then raises, when ambient temperature reaches 65 ℃, it is elongated that memory alloy spring 1 begins to recover, and memory alloy spring 1 restoring force overcomes the resistance of common biasing steel spring 3, drives control stalk 2 and move to the A direction, increase the opening angle of blade of louver window 8, the cooling air quantity of the shutter of flowing through is increased, and water tank 7 heat radiations increase, and cooling temperature of circulating water reduces.When cooling water temperature is reduced to uniform temperature, water tank 7 rear portion ambient temperatures reduce, memory alloy spring 1 restoring force descends, be biased steel spring 3 compressions, drive control stalk 2 to the motion of B direction, blade of louver window 8 opening angles reduce, and cooling air quantity reduces, the water tank heat radiation is reduced, and cooling temperature of circulating water raises.Said process reaches balance in the certain temperature range of cooling circulating water, cooling temperature of circulating water is remained in the optimum temperature range.

The utility model is compared with existing blade of louver window opening angle control method (artificial handle is regulated), has the following advantages:

1, realized the automatically regulating of cooling water temperature, the randomness of having avoided handle to regulate remains in the optimum temperature range cooling water temperature.

2, simple and reliable for structure, can in operator's compartment, reduce by a blade of louver window regulating handle, the maneuvering performance of vehicle is improved.

3, reduced unnecessary heat energy and distributed, energy savings has prolonged driving engine service life.

Fig. 1 is a structure principle chart of the present utility model.
