    A device for a accerating the pushing pressure of a wiper arm
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windshield wiper of an automobile, and more particularly, to an apparatus for increasing pressure of a wiper arm for an automobile, which is capable of improving the pressing force of the wiper blade on the inclined surface of the front window.
    In general, the windshield wiper wipes the front window to prevent the driver's watch from being disturbed in case of rain or snow, and rotates the motor using the electric current of the battery. It is designed to cope with such conditions as rainfall or snowfall.
    In this case, the windshield wiper is supported by an opaper arm rotated along the front window, and the coil spring is installed on the wiper arm so that the wiper blade contacts the front window with a proper force.
    That is, the conventional wiper device that is capable of performing the above function, as shown in the schematic diagram of Figure 1, the head portion 120 is rotatably fitted to the coupling shaft 110 of the wiper ring cage 100, Retainer 130 pivotally coupled to the distal end of the head portion 120, the arm strip 150 coupled to the wiper blade 140 on the other end in a state where one end is fixed to the distal end of the retainer 130, and the retainer ( One end is caught in the hole formed in the inside of 130, and the other end has a structure consisting of a coil spring 160 hooked to the hook of the arm strip 150.
    In addition, the coupling shaft 110 is composed of a housing 111 which is directly coupled to the coupling hole of the head portion 120, and a rotating shaft 112 rotated by a motor along the inner side of the housing 111. It is.
    Therefore, since the arm strip 150 is pulled by the elastic force of the coil spring 160, the wiper blade 140 is elastically in close contact with the front window 170, for example.
    However, since the shape of the front window 170 is a structure in which the end portion is inclined in the state in which the rounded surface is formed as a whole, the pressing pressure of the wiper blade 140 is significantly reduced on the inclined surface. There was a problem.
    In addition, when the coil spring 160 having a strong elastic force is mounted to improve the pressing pressure of the wiper blade 140, the lifespan is not only shortened because an overload is applied to the motor for operating the wiper cage. When the wiper blade 140 moves along the front window 170, there is a problem that the friction noise is increased significantly, especially when the wiper blade 140 is returned from the inclined portion.
    Accordingly, the present invention has been made to solve the problems described above, and relates to a pressing pressure increase device of a vehicle wiper arm to improve the pressing force of the wiper blade on the inclined surface of the front window.
    The present invention for achieving the above object is a head portion pivotably fitted to the coupling shaft of the wiper ring cage, a retainer pivotally coupled to the tip end of the head portion, the other end in the state that one end is fixed to the tip end of the retainer A wiper comprising an arm strip coupled to a wiper blade and a coil spring having one end caught in a hole formed in the retainer and the other end being caught by a hook of the arm strip, wherein the front window is secured between the retainer and the coil spring. It has a structure equipped with a pressurizing device that can improve the pressing force with the photographic part.
    Therefore, according to the pressing pressure increasing device having the above structure, the wiper blade is in close contact with the coil spring when passing through the rounding surface of the front window, and is in close contact with the pressing pressure increasing device when passing through the inclined surface. In this inclined portion, the wiper blade's pressing pressure is significantly increased, and the foreign matter is smoothly removed.

    Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
    Figure 2 is a schematic and partially enlarged view showing the pressing pressure increase device of the automotive wiper arm according to the present invention, Figure 3 is a cross-sectional view showing a coupling axis of the automotive wiper arm according to the present invention, shown in these figures As described above, the head portion 120 rotatably fitted to the coupling shaft 110 of the wiper ring cage 100, the retainer 130 pivotally coupled to the tip portion of the head portion 120, and the tip portion of the retainer 130. One end is fixed to the arm strip 150 coupled to the wiper blade 140 at the other end and a hole formed in the retainer 130 while the other end is hooked to the hook of the arm strip 150 at the end thereof. In the wiper consisting of a jin coil spring 160, between the retainer 130 and the coil spring 160 is equipped with a pressing pressure increase device 10 to improve the pressing force with the inclined portion of the front window In one structure The.
    In addition, a permanent magnet 11 is attached to the inner circumferential surface of the pressing pressure increasing device 10 to the retainer side, and the electromagnet 13 is installed on the upper surface of the permanent magnet 11 in the state in which the compression spring 12 is interposed. It is structured.
    That is, when the electric power is applied to the electromagnet 13, the compression spring 12 is compressed.
    On the other hand, the coupling shaft 110 has a rotating shaft 112 is mounted inside the cylindrical housing 111, the rotating shaft 112 is configured to rotate under the power of the battery.
    Here, the housing 111 of the coupling shaft 110 is formed with a slit groove of a predetermined size corresponding to the rotation angle θ of the wiper cage along the inner surface, the ceramic 21 is a non-conducting groove ) Is coated on the side of which the ceramic 21 is coated, and the conductor 22 is coated on the side portion corresponding to the rotation angle Δθ passing through the inclined surface of the front window.
    In addition, the pivot shaft 112 rotatably mounted in the coupling shaft 110 has a structure in which a contact terminal 23 that can perform a switching role with the housing 111 is integrally formed.
    Hereinafter, described in detail with reference to the accompanying drawings illustrating the operation according to the present invention.
    First, when the wiper blade 140 removes various foreign substances while moving along the rounded surface of the front window 170, the pressurization device 10 is not operated.
    That is, since the contact terminal 23 for switching while contacting the housing 111 of the coupling shaft moves left and right along only the portion of the ceramic 21 coated, the wiper blade 140 has a coil spring 160. It is in a state of being in close contact with the outer surface of the front window 170 only by the elastic force of the).
    If the wiper blade 140 passes through the rounded surface of the front window 170 and passes through the inclined surface of the outer portion, the push pressure increasing device 10 is operated.
    That is, the contact terminal 23 passes through the portion coated with the ceramic 21 and instantaneously makes contact with the conductor 22 to energize the push-pressure increasing device 10, and the electromagnet ( 13) the power of the battery is to be supplied.
    At this time, since the attraction force is applied to the electromagnet 13 and the permanent magnet 11, the compression spring 12 is pressed toward the permanent magnet side, so that the coil spring 160 is pulled.
    Of course, the coil spring 160 is pulled to bring the outer blade 140 closer to the front widow 170.
    On the other hand, when the wiper blade 140 passes through the inclined surface of the front window 170 and the rounding surface, the conductor 22 and the contact terminal 23 are separated from each other, and was supplied to the electromagnet 13. Since the power is stopped, the wiper blade 140 is returned to its original state while the electromagnet 13 is returned by the elastic force of the compression spring 12.
    As described above, according to the device for increasing the pressure of the wiper arm for automobiles according to the present invention, the wiper blade is pressed by the coil spring when passing through the rounding surface of the front window and is pressed when passing through the inclined surface. Since it is in close contact with the augmentation device, the pushing pressure of the wiper blade is significantly increased in this inclined portion, thereby effectively removing foreign substances.
