Description
Technical field
This utility model belongs to electronic throttle technical field, relates to a kind of Small Universal engine air control shutter.
Background technology
At present, the Small Universal machinery such as jetting machine, generating set and water pump is typically using internal combustion engine as power source,
Air throttle, as the important control device of internal combustion engine, has been generally integrated ECU module, for processing the detection signal of each sensor,
Control charge flow rate.ECU module is mainly housed in an ECU housing and is removably pacified by screw by existing air throttle
Install on throttle body, needing after installation, seal member is additionally set each installed surface is sealed, cause number of parts many, dress
Joining complexity, production cost is higher, and poor reliability.
Utility model content
In view of this, this utility model provides a kind of simple in construction, easy to assembly, relatively low small-sized logical of production cost
Use engine air control shutter.
Its technical scheme is as follows:
A kind of Small Universal engine air control shutter, including throttle body, this throttle body has a through air inlet and leads to
Road, it it is critical only that: described throttle body side is provided with the ECU mounting groove caved inward, and passes through encapsulated layer in this ECU mounting groove
Being packaged with ECU circuit substrate, ECU circuit substrate connects wire harness, and this wire harness passes encapsulated layer and extends outward ECU installation
The notch of groove.
Above structure, ECU module is used to be directly encapsulated in ECU mounting groove integrated with throttle body, it is not necessary to
Being separately provided ECU and arrange housing, decrease number of parts, simultaneously because directly use encapsulated layer to be packaged, ECU module is installed
After, it is not necessary to seal member is additionally set and seals, enormously simplify production technology, contribute to reducing production cost.
Further, wire harness employing is welded or other are fixedly attachable on ECU circuit substrate, to avoid wire harness to take off
Fall, and simplify assembly technology.
Further, described throttle body being equipped with throttle plate pin, the head end of this throttle plate pin passes ECU mounting groove groove
The end and after extending to ECU mounting groove, the head end of throttle plate pin is also arranged with position sensor, to facilitate detection throttle opening.
Further, the notch side of described ECU circuit substrate is coated with electrostatic film, can with guarantee ECU circuit substrate
By sealing, and shield external interference.
For convenience of the installation of air throttle, after the tail end of described throttle plate pin is radially across described inlet channel, through air throttle
Mounting bracket is arranged on throttle body.
Described position sensor is near the bottom land of ECU mounting groove.
Described encapsulated layer material is preferably silica gel or epoxy resin.
Beneficial effect:
Using the Small Universal engine air control shutter of above technical scheme, ECU mounting groove is one-body molded with throttle body,
It is after the encapsulation of ECU module, it is not necessary to increase extra seal member, decrease amount of parts, there is simple in construction, easy to assembly,
The advantages such as production cost is low, good reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is perspective view of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of Small Universal engine air control shutter as depicted in figs. 1 and 2, including throttle body 1, this throttle body 1 has
Having a through inlet channel 10, throttle body 1 side is provided with the ECU mounting groove 11 caved inward, in this ECU mounting groove 11
Be packaged with ECU circuit substrate 2 by encapsulated layer, on ECU circuit substrate 2 connect have wire harness 3, this wire harness 3 pass encapsulated layer and to
Extend outward the notch of ECU mounting groove 11.
ECU mounting groove 11 is provided with ECU circuit substrate 2, and it is thin that the notch side of described ECU circuit substrate 2 is coated with electrostatic
Film 6, during assembling, first with silica gel by the clearance seal between electrostatic film 6 circumference and ECU mounting groove 11 sidewall, passes through ring afterwards
ECU circuit substrate 2 and electrostatic film 6 are packaged in ECU mounting groove 11 by encapsulated layer that the encapsulating materials such as epoxy resins are made in the lump,
The electric component of ECU circuit substrate 2 is positioned at the ECU circuit substrate 2 side surface away from inlet channel 10, at ECU circuit substrate 2
On be for good and all fixed with wire harness 3 by welding or other fixed forms, this wire harness 3 is through electrostatic film 6 and encapsulated layer, and along remote
Stretch out from the side of inlet channel 10.
Be equipped with throttle plate pin 4 on described throttle body 1, the head end of this throttle plate pin 4 through ECU mounting groove 11 bottom land and
After extending to ECU mounting groove 11, the head end of throttle plate pin 4 is also arranged with position sensor 5.Wire harness 3 stretches out ECU mounting groove 11
Notch.Described position sensor 5 is near the bottom land of ECU mounting groove 11, and i.e. both are respectively close to inlet channel 10 length direction
Rear and front end.Avoid interfering.
After the tail end of described throttle plate pin 4 is radially across described inlet channel 10, it is arranged on joint through air throttle mounting bracket 7
On valve body 1.It is easy to the installation of whole air throttle, air throttle mounting bracket 7 is also equipped with the parts such as line wheel and facilitates connection to draw
Rope.
It should be noted that foregoing description is only preferred embodiment of the present utility model, the ordinary skill people of this area
Member, under enlightenment of the present utility model, on the premise of this utility model objective and claim, can make multiple
Similar expression, within such conversion each falls within protection domain of the present utility model.
