Abstract
The utility model which relates to an air blower switch and an internal and external gas cycle operation combination block and comprises an upper shell body(1) and a lower shell body(3) that is connected with the upper shell through a light-guide plate (2). The upper end of the upper shell body (1) is connected with a knob (4); the lower shell body (3) is arranged on a bottom plate (5). The air blower switch and an internal and external gas cycle operation combination block are characterized in that a rotating axis wheel (7) is arranged in the lower shell body (3) and a printing circuit board (6) is arranged between the rotating axis wheel (7) and the bottom plate (5), and only one knob is needed for achieving two functions of controlling the speed of the air blower and the internal and external gas circulation air door, and the rotating direction decides the opening and closing of the air door and the gear decides the rotating speed of the air blower, and the operation is very convenient.
Description
Technical field
The utility model relates to a kind of auto parts and components, is that combination block is handled in a kind of double inside and outside gas circulation of blower switch of handiness specifically.
Background technique
Along with development of Chinese economy, people's living standard is also more and more higher, automobile has become one of requisite traffic tool of people, blower motor is relevant, low speed, middle low speed, high speed and five gears at a high speed, inside and outside gas cycle throttle then has standard-sized sheet or two positions of complete shut-down, and control originally just needs a plurality of buttons to realize the control of these functions, complex structure, control loaded down with trivial detailsly, use inconvenient.
As mentioned above, there is following deficiency in prior art: the fingertip control complex structure, control loaded down with trivial detailsly, and handle inconvenient.
Summary of the invention
The utility model has solved the fingertip control complex structure that prior art exists, and control loaded down with trivial detailsly, handles inconvenient problem, and the blower switch of an a kind of the usefulness knob controlling inside and outside gas circulation manipulation combination block of holding concurrently is provided.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: combination block was handled in the gas circulation inside and outside a kind of blower switch was held concurrently, comprise upper shell and the lower shell body that links to each other by light guide plate, described upper shell upper end connects knob, lower shell body is located on the base plate, it is characterized in that being equipped with in the described lower shell body and revolve the axis wheel, this revolves between axis wheel and the base plate and is provided with printed circuit board (PCB).Be connected with leaded light post knob illumination appliance between described upper shell and the knob, this illumination appliance is that step is cylindrical.Described revolve to be connected with in the heart in the axis wheel revolve axle, individual circular hole is arranged in the middle of the described lower shell body, this revolves axle and circular hole mates.Working method of the present utility model is as follows, and revolving axle in the hole, has the location corresponding to interior circulation, outer circulation on upper shell, and the place, location is corresponding to the scram position of blower switch; Blower when running then this positioning means play damping function, the continuation rotation then entered running speed governing position after knob was crossed scram position, the sliding contact that is fixed on the wire-drawing wheel contacts the rotating speed that changes the SC sigmal control blower motor that outputs to brushless electric machine or speed adjusting module with fixed contact on the printed circuit board (PCB), though this moment, wire-drawing wheel still drove the driven wheel rotation, because air door mechanism cam mechanism action of cam is in the location that idling conditions does not influence inside and outside gas cycle throttle.Handling only needs with a knob, just can control standard-sized sheet, the complete shut-down position of pass, low speed, middle low speed, high speed and five gears of high speed and the inside and outside gas cycle throttle of blower motor, simple in structure, easy to operate.
As preferably, each assembly concentric on described this combination block.These assemblies comprise base plate, place printed circuit board (PCB) on the base plate, revolving the axis wheel, be placed in the lower shell body that revolves the axis wheel outside on the circuit board, upper shell that the light guide plate on the lower shell body is connected with light guide plate, place the knob in the hole on the upper shell.
The utility model is skillfully constructed, and has following beneficial effect compared with the prior art:
Manipulation is only with a knob, and rotation direction determines air door switch, and gear decision blower motor rotating speed is simple in structure, easy to operate.

Fig. 2 is a structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1 and Fig. 2, combination block was handled in the gas circulation inside and outside this routine a kind of blower switch was held concurrently, comprise upper shell 1 and the lower shell body 3 that links to each other by light guide plate 2, described upper shell 1 upper end connects knob 4, be connected with leaded light post knob illumination appliance 10 between upper shell 1 and the knob 4, this illumination appliance 10 is that step is cylindrical, and lower shell body 3 is located on the base plate 5, it is characterized in that being equipped with in the described lower shell body 3 and revolve axis wheel 7, this revolves between axis wheel 7 and the base plate 5 and is provided with printed circuit board (PCB) 6.Revolve to be connected with in the heart in the axis wheel 7 and revolve axle 8, in the middle of the described lower shell body 3 individual circular hole 9 is arranged, this revolves axle 8 and circular hole 9 couplings.
Wherein, each assembly concentric on this combination block, these assemblies comprise base plate, place printed circuit board (PCB) on the base plate, revolving the axis wheel, be placed in the lower shell body that revolves the axis wheel outside on the circuit board, upper shell that the light guide plate on the lower shell body is connected with light guide plate, place the knob in the hole (as shown in Figure 1) on the upper shell.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
