Description

Vapor removing device of wind-shield glass of a car}

The present invention relates to a device for removing the inner surface of the windshield glass of the vehicle, and more particularly, a separate wiper on the inside of the windshield glass to operate with the existing wiper mounted on the outside of the windshield glass or to operate manually. By configuring the, it is possible to secure the driving field by effectively removing the mist formed on the interior side of the windshield glass relates to a windshield glass inner surface defogging device of the vehicle capable of safe driving.

In general, the driver is driving while determining the state of the outside of the vehicle through the windshield glass. However, when foreign matter gets caught in the windshield glass due to snow or rain or yellow dust, it is difficult to secure a driving field of view.

The conventional vehicle is provided with a wiper on the windshield glass as one means to solve this problem. The wiper helps to secure the driving field by wiping the surface of the windshield glass according to the operation of the operation switch.

However, when there is a large difference in the indoor and outdoor temperatures due to snow or rain, fog occurs on the inner surface of the windshield glass. Such Kim Seo-rim is becoming a factor that obstructs the driver's view and hinders safe driving.

As a means for improving this point, there is a conventional method using an air conditioning device. That is, when the windshield glass is frosted, a lot of methods to remove the mist by spraying cold or warm air from the air conditioning device to the inner surface of the windshield glass. However, since this method has a limited range in which hot and cold air is sprayed, only the bottom of the windshield glass is locally removed, and in order to frost through the windshield glass, there is a problem of operating the air conditioning device for a long time. It became.

Alternatively, the driver can directly wipe the inner surface of the windshield glass with a cloth. However, the moisture removed in this way will reappear on the surface of the windshield glass over time. In other words, the method of wiping the interior surface of the vehicle glass to secure the driver's vision cannot be a fundamental method of removing moisture, and it is very likely that the driver's nerves are dispersed while the interior surface of the vehicle glass is wiped. .

Another method is to use a dehumidifying agent. The moisture remover can prevent the formation of moisture by spraying on the glass surface where the moisture is formed. However, such a dehumidifying agent also has a problem that must be frequently sprayed on the surface of the windshield glass because the effect does not last long. That is, the dehumidifying agent has a certain period of spraying to the area where moisture is generated, there is an inconvenience that must be carried out continuously. Thus, the use of dehumidifiers has not been a fundamental solution.

The present invention has been made to solve the above problems, and more specifically, by configuring a separate wiper on the inner surface of the windshield glass to operate in conjunction with the existing wiper or manually, the windshield An object of the present invention is to provide an inner surface defogging device of a windshield glass of a vehicle that can effectively remove defogging formed on the interior side of the glass.

Other features, specific advantages, and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments associated with the accompanying drawings.

An indoor wiper for a vehicle according to the present invention includes: an indoor wiper disposed on a rear surface of a windshield glass and rotatably installed through a hinge axis extending on a rotation center line of an outdoor wiper; A magnetic force induction coil installed in the indoor wiper and generating magnetic force; It characterized in that it comprises a switch means for selecting on and off the power supplied to the magnetic force induction coil.

In particular, the hinge shaft is further provided with a return spring for rotating the indoor wiper to its original position.

In particular, the indoor wiper for the vehicle is further provided with a wiper operation knob that can be manually rotated.

According to the present invention has the following effects.

1) The indoor wiper installed on the indoor side of the windshield glass is interlocked by the operation of the outdoor side wiper. Therefore, it is possible to simultaneously remove the fog on the inside and outside of the windshield glass.

2) Since the indoor wiper can be operated manually regardless of the outdoor wiper, the driver can use the indoor wiper arbitrarily if he wants to clean the surface of the windshield glass as well as steaming.

3) Since the operation of the indoor wiper can be easily switched automatically or manually through the switching means, further convenience can be improved.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention.

1 is a perspective view showing the configuration of the defogging device of the inner surface of the windshield glass 200 of the vehicle according to the present invention. As shown in FIG. 1, the wiper second arm 20 and the outdoor wiper blade 30 of the indoor wiper 100 are configured to face each other. Therefore, when the indoor wiper 100 for the vehicle wiping the windshield glass 200 of the vehicle rotates with the hinge shaft 40 as the rotation axis, it is driven like the outdoor wiper 90 containing steel by the principle of the electromagnet. Will be.

This will be described in detail below.

The hinge wiper 40 is connected to the indoor wiper 100 and the outdoor wiper 90 to be driven together. As shown in FIG. 1, the windshield glass 200 of the vehicle is disposed between the indoor wiper 100 and the outdoor wiper 90 of the vehicle. The first arm 10 is hinged to the hinge shaft 40.

The initial position lies on the underside of the windshield glass of the vehicle. However, the indoor wiper 100 of the vehicle starts to move according to the driver's operation.

Then, the outdoor wiper 90 is configured to move in conjunction with the operation of the vehicle indoor wiper 100. The pivot link 50 is disposed on the upper surface of the hinge shaft 40 so as to smoothly move it.

For this configuration, the hinge shaft 40 capable of rotating the outdoor wiper 90 should have a length long enough to operate together with the indoor wiper 100. Otherwise, it is difficult to install the outdoor wiper 90 and the indoor wiper 100 to face each other. In addition, it is not possible to arrange the outdoor wiper 90 within the operating range of the electromagnetic force to move in accordance with the drive of the indoor wiper 100.

A fastening means 60 is disposed below the hinge shaft 40 so as to be connected to the other wipers 90 and 100.

Here, the wiper operation knob 110 is disposed in the first arm 10. The wiper operation knob 110 is configured to manually operate the wiper when the driver of the vehicle changes the power supply from the switch means from on to off.

2 is a perspective view showing the internal structure of the indoor wiper 100 of the inner surface of the windshield glass 200 of the vehicle according to the present invention. As shown in FIG. 2, a magnetic force induction coil 70 is disposed on the second arm 20 of the indoor wiper 100. Thus, when a current flows through the coil 70 of the vehicle wiper 100, a magnetic field is formed by the law of ampere. To this end, a wire for applying power to the magnetic force induction coil 70 is provided inside the second arm 20.

The magnetic field thus formed simultaneously drives the outdoor wiper 90 made of steel. When the power is supplied to the indoor wiper 100 in this manner, the outdoor side wiper 90 and the vehicle indoor wiper 100 move simultaneously.

Of course, if you want to move the indoor wiper 100 of the vehicle separately from the outdoor wiper 90, the power of the switch selection means may be turned off. For this configuration, it is possible to select a manual automatic method according to whether or not the power supply to the vehicle indoor wiper 100.

Figure 3 is a perspective view showing the configuration of the lower end connected to the indoor wiper 100 according to the present invention. As shown in Figure 3, at the end of the lower end is provided with a fastening means 60 that can connect the two indoor wiper (100). The hinge shaft 40 is connected to the fastening means 60 while penetrating the indoor wiper 100.

However, for the manual operation of the indoor wiper 100 should be configured to operate independently of the outdoor wiper 90.

Therefore, if you want to move the indoor wiper 100 independently of the outdoor side wiper 90, the switch means connected to the indoor wiper 100 is switched on to off. When the switch means is switched from on to off in this way, no current flows to the coil 70 anymore. At this time, the magnetic field formed in the coil 70 disappears.

Accordingly, the outdoor wiper 90 does not move, and only the indoor wiper 100 for the vehicle moves by hand.

In addition to this, the indoor wiper 100 also has a function of returning to its original position after completing the defogging operation similarly to the outdoor wiper 90. It is the return spring 80 which has to implement such a function.

This return spring 80 is wound around the hinge shaft 40. Thus, when the defogging operation is completed, the indoor wiper 100 returns to the position by the operation of the return spring 80.

Of course, the windshield glass inner surface defogging device of the vehicle according to the present invention for this configuration is further provided with a wiper operation knob (110). Defogging device of the inner surface of the windshield glass 200 of such a vehicle may be provided with a pair, it may be provided with only one in front of the driver's seat.
