CN202413348U - Cooling/heating controller for vehicle air conditioner - Google Patents

Abstract

The utility model relates to a cooling/heating controller for a vehicle air conditioner, which comprises a gearwheel disc, wherein the gearwheel disc and a skew gear shaft are arranged on the controller main body by a fixation clamp, a water valve lacing wire and a cooling/heating ventilation door lacing wire pass through corresponding holes in the gearwheel plate and are respectively fixed by a lacing wire fixation clamp. According to the cooling/heating controller for the vehicle air conditioner, the structure is compact, the design is reasonable, a fan heater ventilating door and the water valve can be regulated at the same time by turning the knob, can control the flow of the cooling water which flows through the radiating core body can be controlled and further the heat exchange quantity can be controlled while the blowing rate between the cooling wind and the hot wind which blow over the radiating core body is regulated. The will of an operator can be achieved quickly by operating the motion knob. Without increasing the number of the parts, the complication for multiply controlling the fan heater ventilation door and the water valve can be reduced, the use is facilitated, and comfort and user satisfaction can be improved.

Description

A kind of air conditioning for automobiles changes in temperature control structure

Technical field

The utility model relates to a kind of structure of air conditioning for automobiles changes in temperature pattern control.

Background technology

At present, air conditioning for automobiles has important role as the important indicator of car comfort in the car load research and development.As control car load a/c system changes in temperature, pattern, and the control center of wind speed, it is important that the design of air-conditioning control mechanism especially seems.Traditional changes in temperature control generally shows as following three kinds of situation, knob controlling fan heater air door position, and whether control wind blows over the heat radiation core body; Thereby control cold wind or hot blast, no penstock control in the heater unit suction culvert, knob controlling fan heater air door position; Whether control wind blows over the heat radiation core body, thereby control cold wind or hot blast have penstock control in the heater unit suction culvert; But to, manually stir by needs the penstock arm when switching, the penstock in the knob controlling heater unit suction culvert, control cooling water flow; Thereby control heat exchange amount; Because the air-conditioning control mechanism is positioned at the instrument carrier panel midway location,, need in controller, increase a driving lever or knob if want not only to control cooling water flow but also control the fan heater air door position; For more and more becoming more meticulous and development and Design cheaply, this all is serious tests to space and cost undoubtedly.If moreover two controls exist simultaneously, also can cause user's operation mistake, occur as: air door is in thermal site, but penstock cuts off cooling water flow, or air door is in cold position, and penstock does not switch cooling water expansion tank.Can increase the fussy degree of control so again, reduce user satisfaction.

Summary of the invention

The purpose of the utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, and convenient, fast, functional strong, relative users is carried out a kind of air conditioning for automobiles changes in temperature control structure of changes in temperature blocked operation fast.In order to achieve the above object; The technical scheme that the utility model adopts is: comprise toothed disc; Be installed in through geometrical clamp on the controller main body at toothed disc and helical gear shaft, cooresponding hole in the toothed disc is passed in water valve lacing wire and the lacing wire of changes in temperature air door, and is fixing respectively by the lacing wire geometrical clamp.The utility model has the advantages that: compact conformation, reasonable in design; The knob rotation can be regulated fan heater air door and penstock simultaneously; When heat radiation core body air quantity accounting was crossed in the cold and hot wind of adjustment, control flows was controlled heat exchange amount through the flow of heat radiation core body cooling water expansion tank again.Same operational movement knob, fast speed is realized operator's wish more.The utility model does not increase number of components and parts, has reduced the loaded down with trivial details, convenient for users to use of multiple control fan heater air door and penstock, improves traveling comfort and user satisfaction. Description of drawings [0004]Fig. 1 is the utility model structural representation. The specific embodiment [0005]Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.Can know that by Fig. 1 the utility model comprises toothed disc 5, be installed on the controller main body 2 through geometrical clamp 4 that water valve lacing wire 6 is passed cooresponding hole in the toothed disc 5 with changes in temperature air door lacing wire 8 at toothed disc 5 and helical gear shaft 3, fixing respectively by lacing wire geometrical clamp 7.The utility model mainly consists of the following components, changes in temperature knob 1, controller main body 2, helical gear shaft 3, geometrical clamp 4, toothed disc 5, water valve lacing wire 6, lacing wire geometrical clamp 7, changes in temperature air door lacing wire 8.When rotating the changes in temperature knob 1; Power is transferred to toothed disc 5 through helical gear shaft 3; The rotation of toothed disc 5 causes that water valve lacing wire 6 and changes in temperature air door lacing wire 8 do radial motion, the penstock on water valve lacing wire 6 another termination heater unit coolants inlet pipe, changes in temperature air door lacing wire 8 another termination heater unit upper wind door kinematic mechanisms; Thereby control penstock and fan heater air door move simultaneously; When heat radiation core body air quantity accounting was crossed in the cold and hot wind of adjustment, control flows was controlled heat exchange amount through the flow of heat radiation core body cooling water expansion tank again.At first toothed disc 5 and helical gear shaft 3 are installed on the controller main body 2 during making; And with geometrical clamp 4 fixations; Water valve lacing wire 6 and changes in temperature air door lacing wire 8 are being passed in the toothed disc 5 behind the corresponding aperture, with lacing wire geometrical clamp 7 lacing wires 6 of fixation water valve and changes in temperature air door lacing wires 8 respectively.

Claims (1)

1. air conditioning for automobiles changes in temperature control structure; Comprise toothed disc (5); It is characterized in that: be installed on the controller main body (2) through geometrical clamp (4) at toothed disc (5) and helical gear shaft (3); Cooresponding hole in the toothed disc (5) is passed in water valve lacing wire (6) and changes in temperature air door lacing wire (8), and is fixing respectively by lacing wire geometrical clamp (7).
