Abstract
The utility model provides an air inlet joint of an electronic throttle body of a car, which belongs to the technical field of cars and solves the problem that an existing air inlet joint of an electronic throttle body is not easy to be connected with an air filter hose. The air inlet joint of the electronic throttle body of the car is arranged on the throttle body, is tubular and is integrated with the throttle body, the air inlet joint is conical, the outer diameter of the air inlet joint is smaller than the inner diameter of the air filter hose and then gradually transits to be larger than the inner diameter of the air filter hose. The air inlet joint of the electronic throttle body of the car has the advantages of easiness in manufacturing, low difficulty in assembly and the like.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of automotive electronics throttle body, particularly a kind of intake interface of automotive electronics throttle body.
Background technique
Closure is the important control parts of motor car engine.For power character, stationarity and the Economy that improves automobile running, and reduce pollution emissions, each big automaker of the world has released various control characteristic good electron closures and corresponding electronic control system thereof, forms control system of electronic throttle valve (ETCS).Adopt control system of electronic throttle valve, make throttle opening precisely controlled, not only can improve fuel economy, reduce discharging, simultaneously, system responses is rapid, can obtain satisfied handling; On the other hand, can realize the integrated of idle speed control, Ruiss Controll and vehicle stabilization control etc., simplify the control system structure.
For example, Chinese patent discloses a kind of electronic air throttle body [application number is: 03130634.9], comprises closure valve block, throttle plate pin, shell and air flue, and closure valve block and throttle plate pin are fixed, and can rotate in air flue.One stepper motor is arranged, on a motor shaft is arranged, throttle plate pin is driven by motor shaft and does and follow rotation synchronously.Also comprise a throttle plate pin rotational position calibrating device, repacking is put and is comprised a cover trigger signal generator or a cover rotational position countercheck mechanism at least.
But above-mentioned electronic air throttle body intake interface is by the installation of the empty filter of the method guiding flexible pipe of chamfering, because throttle body interface diameter is filtered inner diameter greater than sky, and the engine nacelle space is limited, and it is not too convenient that empty filter flexible pipe is connected with throttle body.And be not easy to make, intake interface comes off easily.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, the intake interface of the automotive electronics throttle body that proposed a kind ofly to be easy to make, assembling difficulty is low.
The purpose of this utility model can realize by following technical proposal:
The intake interface of this automotive electronics throttle body, be arranged on the throttle body, it is characterized in that, this intake interface in a tubular form and with throttle body be integral structure, the external diameter of described intake interface is tapered, and the external diameter of described intake interface is by progressively carrying out the transition to greater than sky filter inner diameter less than sky filter inner diameter.
The intake interface external diameter of this automotive electronics throttle body adopts conical design, is easy to its manufacturing, and can well guides the installation of empty filter flexible pipe, has reduced assembling difficulty; After the moulding, can reprocess, directly can be used as the port that is connected with empty filter flexible pipe it.
In the intake interface of above-mentioned automotive electronics throttle body, be provided with on the described intake interface when the described empty fixed block that can prevent when flexible pipe is placed on the above-mentioned intake interface that empty filter flexible pipe from coming off of filtering.
In the intake interface of above-mentioned automotive electronics throttle body, described fixed block in the form of a ring, and described fixed block is made by steel wire.
Compared with prior art, the intake interface of this automotive electronics throttle body has the following advantages:
1, the throttle inflow interface is with the tb casting, and the intake interface external diameter adopts taper, has increased pattern draft in casting process, has improved casting technique, is easy to casting.
2, the throttle inflow interface adopts and becomes diameter structure, can process again, has simplified manufacturing process, directly as the port that is connected with the sky filter.
3, throttle inflow interface external diameter can be guided the installation of empty filter flexible pipe well by progressively carrying out the transition to greater than sky filter inner diameter less than sky filter inner diameter, has made things convenient for the car load assembling, reduces assembling difficulty.
Description of drawings
Fig. 1 is the structural representation of the automotive electronics throttle body that provides of the utility model.
Among the figure, 1, intake interface; 2, throttle body.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Automotive electronics throttle body as shown in Figure 1 comprises throttle body 2 and is arranged on intake interface 1 on the throttle body 2, this intake interface 1 in a tubular form, and this intake interface 1 is integral structure, casting together with throttle body 2.
Intake interface 1 as shown in Figure 1 is arranged to the tapered structure of external diameter with it, by progressively carrying out the transition to greater than sky filter inner diameter less than sky filter inner diameter, can well guide the installation of empty filter flexible pipe like this, reduces assembling difficulty.
Because intake interface 1 has been arranged to cone structure, then when it is carried out casting, has increased pattern draft, is easy to like this integral body is cast.And the product that processes can reprocess, directly as and the port that is connected of sky filter flexible pipe, simplified manufacturing process.
Because the electronic throttle inner chamber generally is in negative pressure state, then the junction plane at sky filter flexible pipe and throttle inflow interface 1 can produce an impacting force, empty filter flexible pipe and electronic air throttle body 2 are closely cooperated, and for air defense filter flexible pipe comes off, 1 place is provided with fixed block at intake interface.Fixed block in the present embodiment and is made by steel wire in the form of a ring.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as intake interface 1, throttle body 2 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
Claims (3)
1. the intake interface of an automotive electronics throttle body, be arranged on the throttle body (2), it is characterized in that, this intake interface (1) in a tubular form and with throttle body (2) be integral structure, the external diameter of described intake interface (1) is tapered, and the external diameter of described intake interface (1) is by progressively carrying out the transition to greater than sky filter inner diameter less than sky filter inner diameter.
2. the intake interface of automotive electronics throttle body according to claim 1 is characterized in that, is placed in the fixed block that can prevent when above-mentioned intake interface (1) is gone up that empty filter flexible pipe from coming off being provided with on the described intake interface (1) when described empty filter flexible pipe.
