Description

TECHNICAL FIELD [0001] The present invention relates to an intake manifold for an integrated vehicle,

The present invention relates to an intake manifold for a vehicle with a sensor unit, and more particularly, to an intake manifold for a vehicle with a sensor unit capable of simplifying an assembling process by integrally forming a sensor unit in an intake manifold.

A typical internal combustion engine is a power generating device that sucks a fluid such as air or fuel into an engine and burns the fluid in the engine to use the explosive force.

Therefore, in order to properly combust the fluid in the engine, it is important to accurately measure the amount of air supplied into the engine and to supply the proper fuel on the basis thereof.

That is, accurately measuring the amount of air supplied into the engine has a great influence on the performance of the engine.

The air supplied to the engine is supplied to the intake manifold via the air cleaner and flows into the engine through the cylinder head.

In this case, in order to measure the amount of air flowing into the engine, conventionally, an air flow sensor (AFS: air flow sensor), which is installed at the upstream side of the intake manifold and can directly measure the amount of air flow, MANIFOLD ABSOLUTE PRESSURE (MAP) sensors were used to indirectly measure the amount of intake air through the pressure in the folds, and these two methods were used in parallel.

An appropriate fuel amount signal corresponding to the amount of intake air calculated by an electronic control unit (ECU) of the engine is output by the signal detected from the sensor unit, and the fuel is injected to the engine through the injector.

Such a conventional sensor unit includes a housing 10, a connector 20 and a sensor cell 30 accommodated in the housing 10 as shown in Fig.

And a cover 40 formed integrally with the lower end of the housing 10 and having a through hole 42 for communicating the sensor cell 30 with the inside of the intake manifold.

The conventional sensor unit having such a structure is configured such that when the pressure in the intake manifold is transmitted to the sensor cell 30 through the through hole 42 of the cover 40, The resistance value of the resistor 30 is changed, and the change of the resistance value is converted into a voltage output from the printed circuit board and applied to the electronic control device through the terminal 32. [

Here, the conventional sensor and the intake manifold are configured separately from each other, and the sensor unit and the intake manifold are assembled through an assembling process to mount the sensor unit to the intake manifold.

Accordingly, the number of assembled holes for assembling the sensor unit to the intake manifold is increased, and the assembling process is complicated.

In order to assemble the sensor having the structure and the intake manifold to each other, the sensor and the intake manifold were assembled through welding.

Therefore, there is a problem in that it is not easy to carry out a welding operation because a welding process must be performed in a narrow internal space of the intake manifold for mounting the sensor.

In addition, since a separate assembling device is required for the assembling process, a cost is incurred, and a long time is required for the assembling process, resulting in a decrease in productivity.

For the above reasons, in the related art, a method for easily and efficiently mounting the sensor to the intake manifold has been sought, but up to now, satisfactory results have not been obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sensor unit integral type intake manifold for a vehicle which can simplify a manufacturing process for assembling a sensor unit and an intake manifold by integrally forming a sensor unit and an intake manifold together, Manifold < / RTI >

A partition wall dividing the flow of the fluid is disposed at the center of the first through hole so that the fluid contacts the lower surface of the sensor cell.

The sensor cell includes a wing portion formed on an outer circumferential surface of the sensor cell. The sensor cell is protruded from the bottom surface to a length equal to the thickness of the wing portion from the upper surface thereof. The upper end portion of the sensor cell is bent to contact the upper surface of the wing portion, A plurality of engagement members for fixing the movement are formed.

A second through hole is formed in the bottom surface of the coupling member so that the fluid flowing from the outside through the second through hole flows between the wall and the sensor cell and contacts the upper surface of the sensor cell.

Wherein the connector cover comprises: a cover portion seated on an upper portion of the wall to seal the upper portion of the storage space; A terminal housing having one end protruded upward from an upper surface of the cover portion and the other end opened to communicate with the outside and having a terminal groove into which an external terminal is inserted; A terminal formed in a terminal contact portion extending downward from the exposed portion and protruding downward from a lower surface of the terminal housing to be electrically connected to the sensor cell; Wherein the terminal contact portion is bent in a hook shape so that when the external terminal is coupled to the terminal housing, the terminal contact portion is pushed downward by the urging of the external terminal to be supported by the sensor cell and elastically deformed.

The mount portion is protruded from the lower surface of the terminal contact portion in the upward direction so as to prevent the terminal contact portion from being pushed by the pressing of the terminal contact portion.

In the intake manifold for a vehicle integrated with a sensor unit according to the present invention, a base portion for receiving the sensor cell is formed integrally with the mount portion, and a through hole is formed on the bottom surface of the base portion to interlock with the surge tank, And the number of assembling steps for mounting the sensor cell on the intake manifold can be reduced.

In addition, by reducing the number of assemblies for mounting the sensor cells on the intake manifold, it is possible to simplify the assembling process of assembling the sensor cells to the intake manifold.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First Embodiment

FIG. 2 is a perspective view of an intake manifold for a sensor integrated unit vehicle according to a first embodiment of the present invention, FIG. 3 is an exploded perspective view of an intake manifold for a sensor integrated unit vehicle shown in FIG. 2, Sectional view of an intake manifold for a single-unit type vehicle.

2 to 4, the first embodiment includes a surge tank 100, a runner portion 200, and a mount portion 300.

The surge tank 100 is formed with an inlet 110 through which a fluid such as air or fuel can flow from the outside.

A space is formed inside the surge tank 100, and the fluid introduced through the inlet 110 is temporarily stored therein.

The runner portion 200 is connected at one end to the surge tank 100 and at the other end to the cylinder head of the engine to interconnect the surge tank 100 and the cylinder head.

The runner section (200) supplies the fluid temporarily stored in the surge tank (100) to the combustion chamber of the engine through the cylinder head.

The surge tank 100 and the runner unit 200 are obvious to those skilled in the art and will not be described below in order to avoid the gist of the present embodiment.

The mount portion 300 is disposed between the surge tank 100 and the runner portion 200 to couple the surge tank 100 and the runner portion 200 together.

Meanwhile, since the surge tank 100 and the runner unit 200 are manufactured by the general casting method or the injection molding method, it is difficult to integrally form the surge tank 100 and the runner unit 200 together.

Therefore, the surge tank 100 and the runner unit 200 are separately manufactured and then coupled to each other via the mount unit 300. [

The mount portion 300 can be coupled to the surge tank 100 and the runner portion 200 by bolt fastening or welding so as to withstand the pressure of the fluid flowing from the surge tank 100 to the runner portion 200 , Joining by bolt fastening or welding may be combined in various ways.

The mounting portion 300 includes a sensor portion 400.

3, the sensor unit 400 includes a base unit 410 integrally provided on the upper surface of the mount unit 300 and detects the amount of fluid flowing from the surge tank 100 to the runner unit 200 And pressure.

The sensor unit 400 includes a base unit 410, a sensor cell 420, and a connector cover 430.

The base portion 410 protrudes upward from the upper surface of the mount portion 300 and the wall portion 411 in the form of a closed loop is received from the upper surface of the mount portion 300 so that the sensor cell 420 can be received therein. Respectively.

A bottom surface 414 is formed on the lower surface between the walls 411, and the upper surface is opened.

The base portion 410 has a receiving space 412 formed therein by a wall 411 and a bottom surface 414.

Thus, the sensor cell 420 can be easily accommodated in the accommodating space 412 through the opened upper surface of the base portion 410.

Unlike the related art in which the housing 10 accommodating the sensor cell 30 is mounted on the intake manifold, the base part 410, in which the sensor cell 420 is accommodated, It is possible to reduce the number of assembling steps for attaching or assembling the sensor cell 420 to the intake manifold.

In addition, the number of assemblies for mounting or assembling the sensor cell 420 to the intake manifold can be reduced or the assembling process can be simplified.

A first through hole 415 is formed in the bottom surface 414.

The first through hole 415 is formed in the lower portion of the sensor cell 420 housed in the storage space 412 so that the fluid flowing from the surge tank 100 to the runner 200 can be introduced into the storage space 412 It is a passage.

Accordingly, the pressure of the fluid flowing through the first through-hole 415 can be applied to the lower surface of the sensor cell 420, so that the sensor cell 420 can easily detect the pressure of the fluid .

Here, the first through hole 415 may be formed with a partition wall 416 that distributes or guides the flow of the fluid to the center of the passage through which the fluid flows.

The partition wall 416 is formed at the center of the first through hole 415 so that the pressure of the fluid can be uniformly applied to the lower portion of the sensor cell 420.

Although the partition wall 416 is shown as being formed in the first through hole 415 in the drawing, it is possible to apply the fluid pressure evenly to the sensor cell 420 disposed on the upper portion of the first through hole 415 The barrier ribs 416 may be formed in the first through holes 415 as many as possible.

The sensor cell 420 is received in the receiving space 412 of the base 410 and detects the pressure of the fluid flowing from the surge tank 100 to the runner 200 through the first through hole 415.

The sensor cell 420 is provided with a manifold absolute pressure sensor 421, a boost pressure sensor 422, a cell body 423, and a sensor terminal 425.

The manifold absolute pressure sensor 421 detects a change in the pressure of the fluid flowing through the first through hole 415 of the fluid flowing from the surge tank 100 to the runner portion 200.

The boost pressure sensor 422 converts the pressure of the fluid to a voltage.

Although the sensor cell 420 is described as having the manifold absolute pressure sensor 421 and the boost pressure sensor 422 in this embodiment, the amount of air supplied into the engine can be accurately measured, Only one of the manifold absolute pressure sensor 421 and the boost pressure sensor 422 can be accommodated in the sensor cell 420. In addition to the sensors, an air temperature sensor (ATS) By accommodating the same sensor, the fluid flowing from the surge tank 100 to the runner portion 200 can be appropriately flowed.

The cell body 423 is a body in which a sensor such as a manifold absolute pressure sensor 421 or a boost pressure sensor 422 can be received and is seated on the bottom surface 414 of the storage space 412, The high-temperature chamber is bonded by unnecessary room-temperature curing glues.

Therefore, the cell body 423 can easily protect the manifold absolute pressure sensor 421 or the boost pressure sensor 422 from external impacts.

The sensor terminal 425 is mounted on the cell body 423 in such a manner as to protrude outward in a direction in contact with the terminal 435 and is connected to the manifold absolute pressure sensor 421 or the boost pressure sensor 422 ) And the electronic control unit (ECU: Electronic Control Unit) of the engine are electrically connected to each other.

The sensor terminal 425 includes a receiving portion 426 having one end received in the cell body 423 and in electrical contact with the manifold pressure sensor or the boost pressure sensor 422 and the other end connected to the side surface of the cell body 423 And a terminal contact portion 427 which is protruded from the connector cover 430 and is electrically connected to the connector cover 430.

Here, the terminal contact portion 427 is formed in a planar shape so as to be supported by the support of the bottom surface 414.

The connector cover 430 is disposed on the upper portion of the base portion 410 to seal the upper portion of the storage space 412.

Therefore, the connector cover 430 is prevented from detaching the sensor cell 420 stored in the storage space 412 to the outside.

An external terminal electrically connected to the electronic control unit is inserted into the connector cover 430 to electrically connect the sensor cell 420 housed in the storage space 412 and the electronic control unit.

The connector cover 430 includes a cover portion 431, a terminal housing 433, and a terminal 435.

The cover portion 431 is formed in the same area as the circumference of the wall body 411 and is seated on the upper portion of the wall body 411.

Thus, the cover portion 431 can close the upper portion of the storage space 412.

The cover unit 431 can protect the sensor cell 420 inserted in the storage space 412 from foreign substances introduced from the outside of the storage space 412 and thereby increase the service life of the sensor cell 420.

The engaging groove 413 is formed along the upper surface of the wall body 411 and the engaging projection 432 is formed in a shape corresponding to the engaging groove 413 and protrudes downward from the lower surface of the cover portion 431 .

The cover portion 431 and the wall body 411 can be easily coupled to each other by the engagement of the engagement groove 413 and the engagement protrusion 432. [

The terminal housing 433 has one end protruded upward from the upper surface of the cover portion 431 and the other end opened to communicate with the outside to form a terminal 435 groove into which the external terminal is inserted.

The terminal housing 433 is formed with the groove of the terminal 435 so that an external terminal electrically connected to the electronic control unit can be easily inserted into the terminal housing 433 and the sensor cell 420 housed in the housing space 412 ) And the electronic control device can be electrically connected with each other easily.

The terminal 435 is mounted so as to protrude outward from the terminal housing 433 and is electrically connected to the sensor terminal 425.

The terminal 435 can easily connect an external terminal connected to the electronic control device to the manifold absolute pressure sensor 421 or the boost pressure sensor 422 accommodated in the cell body 423 or the like.

The terminal 435 has an exposed portion 436 whose one end is exposed upwardly from the groove of the terminal 435 and the other end which extends downward from the exposed portion 436 and protrudes downward from the lower surface of the terminal housing 433 And a terminal contact portion 437 which is electrically connected to the sensor terminal 425.

The terminal contact portion 437 is connected to the terminal contact portion 427 of the sensor terminal 425 when the external terminal is coupled to the connector cover 430 and the sensor terminal 425 is forcibly pressed by the external terminal. It is preferable that the contact portion 437 is bent in a hook shape so as to prevent the contact portion 437 from being broken.

As a result, the terminal contact portion 437 is elastically deformed in the pressing direction of the external terminal even when the sensor terminal 425 is pressurized by the external terminal, thereby preventing the terminal contact portion 437 from being broken.

4, the terminal contact portion 427 is provided so as to prevent the external terminal electrically connected to the electronic control device from being damaged by unreasonable pressing of the external terminal when the external terminal is coupled to the connector cover 430 And is preferably bent in a hook shape.

This prevents the terminal contact portion 427 from being deformed elastically in the direction in which the external terminal is pressed against the terminal contact portion 427 even when the external terminal is pressurized excessively.

At this time, although the terminal contact portion 437 is resiliently deformed by the pressure of the sensor terminal 425 to prevent breakage, the terminal contact portion 437 is elastically deformed, and the terminal contact portion 437 is moved in the leftward direction with respect to the cell body 423 shown in FIG. There is a case where it is forcibly pushed.

In order to prevent this, the anti-jamming ribs 440 are formed on the lower surface of the base portion 410 in the left direction with respect to the cell body 423 shown in Fig.

The anti-jamming ribs 440 prevent the terminal contact portion 427 formed in a hook shape by the urging of the terminal contact portion 437 from being pushed in the leftward direction with respect to the cell body 423 shown in Fig.

The anti-jamming ribs 440 protrude upward from the bottom surface 414 of the base portion 410.

This can effectively prevent the terminal contact portion 427 from being excessively pushed in the leftward direction with respect to the cell body 423 shown in Fig. 4 by the pressing of the terminal 435 terminal.

Although the terminal contact portion 427 and the terminal contact portion 437 are formed in the shape of a hook in the present embodiment, it is possible to prevent the terminal contact portion 427 and the terminal contact portion 437 from being damaged by the pressing of the external terminal Only one of the terminal contact portion 427 or the terminal contact portion 437 may be formed in a hook shape.

Hereinafter, the fluid flowing inside the intake manifold for a vehicle with a sensor unit according to an embodiment of the present invention will be described.

5 is a cross-sectional view showing the flow of the fluid in the intake manifold for a sensor integrated unit vehicle shown in FIG.

As shown in FIGS. 2 and 5, a fluid such as air or fuel flows into the interior of the surge tank 100 through the inlet 110 of the surge tank 100.

The fluid stored in the surge tank 100 flows from the surge tank 100 to the runner portion 200 when the engine is driven.
