Description

Register fixing structure for blower motor of automobile

The present invention relates to a resistor fixing structure for a blower motor of a vehicle for adjusting a speed of a blower motor of a vehicle and fixing a resistor which is a safety device that protects the blower motor when the motor is restrained. A resistor fixing structure for a blower motor of a vehicle is disclosed.

The air conditioner of the vehicle includes a blower unit that draws air from the outside through an air intake duct and supplies it to a heat exchanger to blow cold or warm air into the room. The blower unit includes a blower case, a blower motor installed under the blower case, and a centrifugal fan that is blown by the shaft of the blower motor to rotate in the blower case. When the air conditioner is operated for a long time, the blower motor is also driven for a long time, so the blower motor is subjected to a large load so that the motor burns out. Therefore, it is necessary to protect the motor from being burned out.

The resistor is used as a safety device to control the blowing speed and to protect the motor when the motor is locked, and has a temperature fuse and a resistor coil. That is, it controls the blowing speed by the operation of the blower switch (not shown) installed on the driver's front surface, and protects the motor by stopping the driving of the motor by shorting the temperature fuse by resistance heat when the blower motor is overloaded. Done. Since the resistor itself generates a lot of heat, the resistor is mainly installed inside the discharge port side of the blower case in consideration of the cooling property of the resistor. However, when it is difficult to install the inside of the blower case due to the assemblability, it is installed inside the radiator case. There is also.

As described above, in order to fix a resistor installed in the blower case or the radiator case (hereinafter, only the example of fixing the resistor in the blower case) will be described. Coupling flanges 7 having fastening holes formed on both sides of the bottom periphery are respectively installed, and a lower portion of the coupling flange 7 is connected to a temperature fuse of the resistor 6 and wirings with the resistor coils for wiring with a blower motor (not shown). Connector 8 is installed. That is, the coupling flange 7 is provided between the register 6 and the connector 8. Therefore, when the register 6 is to be fixed, the register 6 is inserted into the blower case 9 through an insertion hole formed at one side of the blower case 9 so that the upper surface of the coupling flange 7 is blower case ( 9), and then fasten the register 6 to the blower case 9 by fastening the screw 91 to the blower case 9 from the bottom through both fastening holes of the coupling flange 7 respectively. It can be inserted and fixed inside.

However, in the conventional resistor fixing structure as described above, since the structure to be fixed by the screw teeth 91 is adopted, assembling property falls.

In addition, due to the characteristics of the car, the coupling part is loosened when the screw (91) is loosened due to the characteristics of the vehicle, and the register (6) is easily shaken and damaged by the impact or vibration, which causes noise, and also loosens the coupling part. Air leaks through the gaps, which reduces the cooling performance or heating performance.

In addition, when the blower unit is repaired or the register 6 is replaced, if the register 6 is fixed by the screw 91, the operating space of the driver for releasing the screw 91 is narrow, so that the register 6 Not only is difficult to separate from the blower case 9, but also takes a long time to separate.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a register fixing structure that can easily fix / remove a register to / from a blower case in a one-touch manner.

Another object of the present invention is to ensure that the register remains firm even when a shock or vibration is applied while driving a vehicle, thereby preventing damage to the register and preventing noise from occurring. To provide a fixed structure.

21: hole 23, 231: hook

24, 241: rib 25, 251: gripping protrusion

41: insertion hole 43: hanging hole

In order to achieve the above object, the present invention is fixed to the outer peripheral surface of the blower case a coupling flange formed between the resistor and the connector is inserted into the blower case through the insertion hole of the blower case and having a connector at the bottom 1. A resistor fixing structure for a blower motor of an automobile for fixing a resistor, comprising: both holes respectively formed through both sides of the coupling flange; Ribs are integrally installed on one side of each hole, and both hooks having gripping protrusions extending obliquely upward from the upper end of the ribs and inserted into a bore hole formed in a blower case with a free end bent horizontally. Characterized in that made.

In addition, the present invention is a vehicle for fixing the register by fixing the coupling flange formed between the resistor and the connector to the outer peripheral surface of the blower case is inserted into the blower case through the insertion hole of the blower case and having a connector at the bottom A resistor fixing structure for blower motors, comprising: both holes respectively formed through both sides of the coupling flange; Ribs are integrally installed in the front and rear directions in the center of each hole, and both grips are extended and inclined upwardly from an upper end portion of the ribs, and the free ends are inserted into a hanging hole formed in a blower case by bending in opposite directions. It characterized in that it comprises both hooks having a projection.

The hook may further have both elastic knobs extending downwardly from both grippers and protruding below the holes of the coupling flange.

When the register is fixed inside the blower case by the register fixing structure of the present invention configured as described above, the gripping protrusions of the hooks formed on both sides of the coupling flange are inserted into the bore hole formed on both sides of the insertion hole of the blower case. If you push up the coupling flange while inserting the register through the insertion hole of the blower case, the gripping protrusion is raised and pushed by the gripping hole to accumulate the elastic force, and the moment when the free end of the gripping protrusion protrudes into the blower case, The free end of the gripping protrusion hangs the hanging ball. Therefore, not only can the register be held firmly, but also the shock and vibration can be held firmly, and the airtightness can be well maintained.

On the other hand, when the fixed register is removed, for example, when the driver is inserted into the ruler hole of the blower case, the gripping protrusion is pushed by the thickness of the inserted driver, and the free end of the gripping protrusion is placed at the position where the free end of the gripping protrusion can escape. In other words, registers can be easily removed without running the driver. In this way, when the resistors are provided with hooks with elastic handles when the resistors are separated, when the elastic handles are moved in opposite directions, the free ends of both gripping protrusions face each other, so that the distance between both gripping stones becomes narrower. All of them are placed in a position where they can escape through the hole, so the detachment of the register can be performed more easily.

Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments based on the accompanying drawings.

<Example 1>

In addition, it is preferable that one side of the lower end of the inner circumferential surface of the ruler hole 43 corresponding to the tapered portion formed at the end of the horizontal curved portion of the gripping protrusion 25 is also tapered. Therefore, when the gripping protrusion 25 is inserted into the gripping hole 43, the tapered portion formed in the horizontal bent portion of the gripping protrusion 25 rises upward while contacting the taper portion of the gripping hole 43, so as to the gripping hole 43. Insertion of the gripping protrusions 25 may be performed easily.

On the other hand, to remove the register (1) fixed to the blower case (4), for example, by inserting a screwdriver in the hook hole 43 and pushing the gripping protrusion 25 to the opposite side to hang the upper surface of the hook hole 43 The horizontal bent portion of the gripping protrusion 25 is moved to a position where it can be pulled out from the ruled hole 43, and in this state, when the coupling flange 2 is pulled out downward, the gripping protrusion 25 passes through the ruled hole 43. At the same time, the register 1 may be pulled down through the insertion hole 41 of the blower case 4.
