Description

[0001] The present invention relates to an aspiration motor and an in-car sensor using the same,

The present invention relates to an aspiration motor, and more particularly, to an aspiration motor and an incase sensor using the same.

Generally, the automobile has an air conditioner for indoor heating or cooling.

In order to improve the convenience of the driver, the automobile air conditioner is being converted into an automation device. For this purpose, an in-car sensor for automatically measuring the temperature of the automobile room is essentially installed in the air conditioner.

An in-car sensor is installed on the back surface of an automobile grill or an instrument panel. The in-car sensor sucks indoor air through an aspirator system or a ventilation system, It senses the temperature of automobile room air with an inca sensor installed in the air flow.

Here, the earth sensor type incase sensor uses an aspiration motor to inhale the room air to measure the room temperature of the automobile.

Korean Registered Utility Model No. 0364916 discloses an incinerator assembly for an air conditioner comprising an engaging portion provided on an inner side of a grill opened toward a vehicle interior, a case mounted on the engaging portion, and an incase sensor installed in the case. It is possible to reduce the resistance of the air flow by reducing the resistance element against the air flow by making the cross sectional area of the air flow path from the upstream to the downstream constant. However, by using a universal motor for the assembly related to the air resistance of the incense sensor, The specific structure of the structure of the firing motor can not be known.

Meanwhile, the inca sensor disclosed in Korean Patent No. 0887535 filed by the present applicant is capable of improving the productivity and reducing the defective rate. However, since the bottom surface of the stator support plate occupying a relatively large area in the stator is coupled to the top surface of the control PCB, There is a structural inconsistency that this inca sensor has a limitation in reducing the manufacturing cost because it is inevitable to use a double-sided control PCB having a high part price because of lack of spatial freedom of the top surface of the control PCB.

Therefore, the present inventors invented and invented the structural features of the earth-filling motor which can dramatically simplify the research of the earth-filling motor that can reduce the component cost and repair the faulty element, Which is a more economical, usable and competitive inspection motor and incase sensor capable of reducing manufacturing cost and improving reliability.

Generally, a Hall sensor for generating a position signal of the rotor is required to be mounted on the upper surface of the control PCB since it is disposed close to the rotor. In the structure in which the bottom surface of the stator support plate is coupled to the top surface of the control PCB as in the above-mentioned patent, the space for mounting the components on the top surface of the control PCB is insufficient.

In the above patent, a large mounting area is required because the active components constituting the motor driving circuit mounted on the control PCB are not integrated components but are formed as discrete components such as switching transistors.

Therefore, in the above-mentioned patent, there is a problem that a Hall sensor is mounted on the upper surface of the control PCB, and an expensive double-sided PCB is mounted on the lower surface of the control PCB so that various components constituting the motor driving circuit can be mounted have.

In addition, in the above-mentioned patent, since a plurality of components constituting the motor driving circuit must be SMD-mounted on both sides of the PCB, the process cost of mounting these components on both sides increases, productivity is lowered, defective products are generated and reliability is lowered.

[ . A back yoke 540 is positioned on the outer periphery of the bearing seat 530. The back yoke 540 and the bearing seat 530 may be embedded in the body 590 or the stator supporting plate 550 and the stator supporting plate 550 may be mounted on the lower portion of the body 590, And may be defined as an area of the stator 500 having an area relatively larger than the area of the body 590. [ A part of the outer circumferential surface of the body 590 serves as a bobbin.

A coupling protrusion 560 is formed in the stator supporting plate 550 and a coupling hole 220 into which the coupling protrusion 560 is inserted is formed in the PCB 200 for control. The coupling protrusion 560 of the stator supporting plate 550 is inserted into the coupling hole 220 of the control PCB 200 and then the coupling protrusion 560 is thermally fused with the ultrasonic wave to connect the stator 500 and the control PCB 200 .

The center hole 501 is formed in the body 590 and the sleeve 510 for supporting the shaft 120 is positioned in the center hole 501. The shaft 510 is disposed in the center hole 501 Respectively. The rotor 100 is integrally coupled to the shaft 120, and the rotor 100 includes a magnet 150 having six poles, for example, of a split magnetization or a split magnetization. In the motor structure of the present invention, a ferrite magnet having a lower part price than the Nd magnet can be applied to the magnet 150, and in this case, the same performance as that adopted by the Nd magnet can be realized.

Further, a circular bearing sheet 530 positioned under the center hole 501 of the body and a back yoke 540 for forming a magnetic circuit are inserted at predetermined positions, and are injection-molded by insert molding An insulating wire is wound around the space formed by the body 590 of the stator 500 to form the stator coil 520.

That is, the circular bearing sheet 530 is positioned below the center hole 501, the hexagonal back yoke 540 is inserted at a predetermined position according to the magnetic circuit, and the thermosetting resin is integrally molded in an insert molding manner Can be molded.

The control PCB 200 supplies a driving signal to the stator coil 520 and the stator 500 is inserted into the insertion hole 210 of the control PCB 200 and then the stator 500 is connected to the control PCB 200 .

Therefore, when power is supplied to the stator coil 520 of the aspiration motor, the rotor 100 rotates, and the impeller 130 integrally formed with the rotor 100 is rotated by the sleeve 510 at the center, 120 are supported and rotated to allow air to flow in and out.

2, the body 590 of the stator 500 is inserted into the insertion hole 210 of the control PCB 200, and the lower surface of the control PCB 200 is in contact with the stator supporting plate 550. At this time, the vibration and noise preventing sheets 310 and 320 are interposed between the stator supporting plate 550 and the control PCB 200. It is preferable that the vibration and noise preventing sheets 310 and 320 are attached to the lower surface of the control PCB 200 and then the body 590 of the stator 500 is inserted into the insertion hole 210 of the control PCB 200. In other words, the vibration and noise preventing sheets 310 and 320 are positioned between the stator supporting plate 550 and the control PCB 200 so that the vibrating and noise preventing sheets 310 and 320 are formed by the shortest vibration and noise generated from the rotor 100, So that the occurrence of vibration and noise can be minimized.

FIG. 3 is a perspective view showing a control PCB applied to an embodiment of the present invention, FIG. 4 is a perspective view illustrating a stator applied to an embodiment of the present invention, and FIG. 5 is a cross-sectional view of a stator according to an embodiment of the present invention. And FIG. 6 is a perspective view of a stator and a control PCB according to an embodiment of the present invention.

3, the control PCB 200 is provided with an insertion hole 210 for inserting the body of the stator into a central region thereof, and first and second long holes 261 and 262, which are communicated with the insertion hole 210, is formed, the first and second janghol (261 262), and a is adjacent to each through the first to fourth coil terminal pin insertion holes (231 232 233 234) is formed, the coupling holes 260 are spaced apart from the insertion hole (210) Respectively. Also, the control PCB 200 is formed with a plurality of terminal pin insertion holes 251, 252, 253, 254, 255, and 256 through which terminal pins are inserted.

4 and 6, first and second coil guides 571 and 572 extending from the body 590 of the stator 500 protrude from the upper surface of the stator support plate 550, and first and second coil guides 571 and 572 are formed with first and second coil guide grooves 571a and 571b through which coils are inserted. A plurality of coil terminal pin insertion holes 281, 282, 283, 284, 285, 286, 287, 288 are formed in the stator supporting plate 550 adjacent to the first and second coil guides 571, 572.

The body 590 of the stator 500 is inserted into the insertion hole 210 of the control PCB 200 shown in Fig. 3 and the upper surface of the stator supporting plate 550 is brought into contact with the lower surface of the control PCB 200. The coupling protrusion 560 and the coil guide 571 of the stator supporting plate 550 are coupled to the coupling hole 260 of the control PCB 200 and the first and second holes 261 and 262, respectively.

After the physical connection and alignment between the stator 500 and the control PCB 200 are completed, the coupling protrusion 560 is thermally fused with the ultrasonic wave to fix the stator 500 and the control PCB 200. Since the vibration and noise preventing sheets 310 and 320 are attached to the lower surface of the PCB 200 for control, after the body 590 of the stator 500 is inserted into the insertion hole 210 of the control PCB 200, The vibration and noise preventing sheets 310 and 320 are interposed between the body 590 of the stator 500 and the control PCB 200 when the upper surface of the support plate 550 contacts the lower surface of the control PCB 200. The positions of the vibration and noise preventing sheets 310 and 320 are not limited to those shown in FIG. 5 but may be any position on the lower surface of the control PCB 200, which may be interposed between the body 590 of the stator 500 and the control PCB 200 And the number of vibration and noise preventing sheets 310 and 320 can be freely selected and applied.

The back yoke 540 is embedded in the stator 500 by insert molding. In order to prevent the back yoke 540 from being swept away by the pressure of the thermosetting resin as a molding compound during molding, a guide pin (not shown) for fixing the position of the back yoke 540 may be used. A plurality of guide holes 580 are formed vertically from the upper surface of the body 590 of the stator 500 to the side surface of the back yoke 540. A guide hole 580 is formed on the upper surface of the body 590 of the molded stator 500 when the position of the back yoke 540 is held by the guide pin and the guide pin is detached before the thermosetting resin is completely cured. As a result, the back yoke 540, which is insert molded, can be appropriately positioned inside the stator 500 to prevent the performance of the aspiration motor and the occurrence of defects.

The lower surface of the control PCB 200 is in contact with the stator 500 and the upper surface thereof is formed with a printed circuit based on a circuit diagram similar to that of the circuit diagram of Figure 7. A motor driving chip 610, A constant voltage regulator chip 620 for providing a stable power to the driving chip by making the voltage constant, and a plurality of passive elements are mounted.

On the other hand, in the prior art, since the bottom surface of the stator supporting plate, which occupies a relatively large area in the stator, is coupled to the top surface of the control PCB, the space for the top surface of the control PCB is insufficient. In the present invention, by using a single-sided PCB on which elements having reduced number of parts are disposed by applying a motor driving chip and a constant voltage regulator chip, the cost of parts can be reduced.

In addition, it is possible to increase the degree of spatial freedom with respect to the upper surface of the control PCB 200 so that the Hall element (not shown) can be mounted on the control PCB 200 together with the motor driving chip and the constant voltage regulator chip, will be. As a result, it is possible to prevent the occurrence of defects and the reliability degradation due to the misalignment that may occur between the Hall element (not shown) and the back yoke 540 by the insert molding in the stator 500, .

The Hall element is mounted on the control PCB 200 previously set according to the magnetic circuit formed by the back yoke 540 so that the Hall element and the back yoke 540 are simultaneously assembled with the stator 500 and the control PCB 200, A magnetically aligned alignment between them can be achieved. In addition, when a bad start phenomenon occurs in which the Hall element can not detect the polarity of the magnet, a simple repair process of adjusting the mounting position of the Hall element in the control PCB 200 is performed to eliminate defects, .

Conventionally, since the Hall element and the back yoke 540 are insert molded in the stator 500, the stator 500 is classified as defective when the start failure is caused by the Hall element, There was nothing.

On the other hand, the Hall element is located at the dead point where the polarity of the magnet can not be detected, so that the back yoke 540 and the Hall element must be set in a fixed direction and position so as to prevent the starting failure phenomenon.

For example, it is preferable to position the Hall element by approximately 1/4 the width of the pole, that is, by 15 degrees from the interface between the edge of the hexagonal back yoke 540 and the magnetic pole, This is because it is 1/4 or 3/4 of the magnetic interface of the magnet.

When the back yoke 540 and the Hall element are set and the driving of the aspiration motor is stopped, the center of the magnet is attracted to the back yoke 540 by the magnetic phenomenon between the magnet of the rotor and the back yoke 540, (The area of the portion where the magnet and the back yoke 540 overlap), that is, the corner of the back yoke 540 faces the center of the magnet.

As a result, the Hall element is automatically stopped at a point deviated by 15 degrees from the interface of the magnetic pole, so that the Hall element can be prevented from being located at the dead point where the polarity of the magnet can not be detected.

These coil terminals 581 and 582 can be realized as conductors having excellent electrical characteristics.

When the start / end wiring of the stator coil is wound around the terminals of the coil terminals 581 and 582, it is preferable to perform soldering for preventing the wiring from being loosened and maintaining the contact. The coil terminals 581 and 582 are coupled to the stator support plate 550 so that the start / end wiring of the stator coil is brought into contact with the terminals of the coil terminals 581 and 582. Then, the body of the stator 500 is inserted into the control PCB 200 And inserted into the holes.

The pins protruding from the first and third coil terminal pin insertion holes 231 and 233 adjacent to the insertion hole 210 of the control PCB 200 are for fixing the coil terminals 581 and 582 and the stator support plate 550, And the third coil terminal pin insertion holes 231 and 233 do not contact the control PCB 200 to avoid interference with the control PCB 200.

And is electrically connected to the coil terminals 581 and 582 and the circuit wiring of the control PCB 200 by being soldered to the pins protruding from the second and fourth coil terminal pin insertion holes 232 and 234 adjacent to the outer edge of the control PCB 200 .
