CONTROL DEVICE OF WIRELESS HELMET

Technical Field The present invention relates to a control device of wireless helmet, in which a transparent front cover of the helmet is automatically or manually opened/closed and an operation of a brush for rain mounted on the cover can be controlled by pushing multi-step switches installed on a handle of motorcycle, especially related to an automatic device for opening/closing the transparent front cover of the helmet, in which by installing a nut on the outer surface of upper part of a ball screw connected to a driving motor to be moved up and down, and installing a hinge part for opening/closing the front cover on a side of the nut, the front cover is opened/closed automatically and easily by driving simply the motor in the helmet to prevent an accident due to careless, a control device of wireless helmet capable of controlling a front cover brush, in which a driving motor and a driving pulley connected to a rotation axis are installed on a side of a supporting plate mounted on the upper side of the front cover, a rotation pulley is installed on the other side of the supporting plate and connected with a belt, a rubber brush is connected on the belt through a fixing part to be moved right and left by the pulleys, and a rubber brush connected a belt is in contact with tightly the front cover and can be moved right and left by controlling multi-step buttons on a handle, thereby establishing a broad and clear field of vision in the rainy or snowy day and preventing an accident due to careless.

Background Art In conventional helmet for motorcycle, a driver would move up and down a front cover installed on the front side of helmet by oneself in order to open and close the cover in driving. Such manual opening and closing of the front cover sometimes brought about an accident, as it is impossible to maintain the stability of handle in driving. In order to overcome above problems, proposed was an apparatus which opens and closes automatically the front cover by simple operation of a switch in driving. As shown in Fig. 3 and 4, according to Korean Publication No. 2003-0011949, a worm wheel 414 is installed on a front cover 411 on a helmet 41 0 and is engaged with a worm gear 422 to be rotated by a driving motor 424 and to open and close the front cover. A rechargeable generator recharged by a vane turning with the wind and a radio receiving part 300 for wirelessly operating the driving motor 424 are installed on the main body of helmet 410. Therefore, when the driving motor 424 is driven by a signal of radio receiving part, the worm gear 422 and the worm wheel 414 are rotated by the driving motor 424 to open and close the front cover 411 of helmet 410. As the worm wheel 414 and the worm gear 422 for opening/closing the front cover 411 on the helmet 410 is, however, positioned on a part corresponding to the ear of driver, the driver can feel severe noise generated when opening/closing the front cover 411. Further, as the driving motor 424 for opening/closing the front cover 411 is driven through the vane and the rechargeable generator and installation of the motor, the cover and the generator is difficult, the fabrication and installation of a device for opening/closing the front cover is also difficult. In addition, as the opening/closing of the front cover 411 is not operated full-automatically, there is a problem that the front cover is opened and closed manually as needed. In conventional helmet for motorcycle, when driving in the rainy day or the snowy day, it is difficult to get a clear field of vision due to the rain or the snow impacting against the front cover. Therefore, the driver would wipe away the rain or the snow and drive the motorcycle with the front cover opened. As described above, in case of wiping away the rain or the snow and driving with the front cover opened, an accident can be occurred because it is impossible to maintain the stability of handle or a clear field of vision in driving. Thus, a front cover brush for helmet in which the front cover of helmet is wiped in driving was proposed in order to overcome above problem. As shown in Fig. 5 and 6, according to Korean Publication No. 2003-0011949, the front cover brush is constituted such that a worm gear connected a motor and a worm wheeI(not shown) are installed in a upper and lower cases 501 and 502 to operate a crank on a metal fixing plate and a shock-absorbing rubber plate. As the crank is connected to a guide bar 514 of a brush 515, the brush 515 can wipe a front cover 504 of helmet 503. In conventional helmet using the front cover brush, when the worm gear and the worm wheel in the upper and the lower cases 501 and 502 are driven by the motor to operate the crank(not shown) on the metal fixing plate and the shock-absorbing rubber plate, the crank moves the guide bar 514 right and left to rotate the brush 515 connected to the bar 514 to wipe the front cover 504 of helmet 503. As the front cover 504 of helmet 503 has a curved surface and the brush is shaped as a straight line type, however, the front cover 504 is wiped poorly and the right and left upper portions of the cover can not be wiped. Therefore, a broad field of vision can not be established. Further more, as the upper and lower cases 501 and 502 is positioned on a portion corresponding to the jaw of driver, in case of accident, the jaw can be damaged by the cases. Further, as the worm gear and the worm wheel are positioned in separate case respectively and connected to the crank through the metal plate and the rubber plate in order to operate the brush 515 for the front cover 504 of helmet 503, the fabrication and installation is very difficult. Further, as the activation of the brush is done manually during driving, an accident can be occurred because it is impossible to maintain the stability of handle.

Fig. 7 is a view illustrating a structure of a front cover opening/closing device according to the present invention, and Fig. 8 and Fig. 9 are views illustrating a schematic installation of a front cover opening/closing device according to the present invention. In drawings, the front cover opening/closing device opens/closes a front cover 710 of helmet 700 by a signal from a button on a handle of motorcycle, and is structured such that in a driving part 870, a decelerator 900 is installed on a side of a driving motor 880 having a battery 890 therein, and a ball screw 850 is connected to the decelerator 900 and is rotated by the driving motor 880. Further, a nut 860 is engaged with an upper side of the ball screw 850 to go up or go down and a friction member 830 is installed between the circumference of the nut 860 and the inner side of a going up and down part 820. Therefore, the going up and down part 820 goes up and down by the going up and down of the nut 860 connected to the ball screw 850. A supporting part 840 is installed on the upper end of the going up and down part 820 and one end of a wire 720 is connected to the supporting part 840 to be pulling up and down by the movement of the going up and down part, thereby constituting a wire transfer part 730. In the wire 720 connected to the supporting part 840 of the going up and down part 820 and moved up and down integrally with the nut 860, the other end of the wire 720 is passing through a fixing part 740 installed on the helmet 700 and connected to a hinge part 750 on the upper end of a front cover 710. A front cover 710 is opened/closed by the pulling up and down of the wire 720. As such constructed is a front cover opening/closing part 800. The reference number 760 is a tube, which surrounds the wire 720 connected to the supporting part 840 of the going up and down part 820 for opening/closing the front cover 710. The reference number C is a radio receiving part having an antenna and operating the driving motor 880 by a signal from a radio switch. Fig. 10 is a schematic view illustrating a brush installed on the front cover of the helmet, and Fig. 11 and 12 are views illustrating a structure and essential part of the brush. In the drawings, a supporting plate 970 having a curved surface to be engaged with the upper end of the front cover 710 and a cover-engaging groove 980 formed on its lower portion is installed on the upper side of the front cover 710 of the helmet 700, a first recess 950 is formed on one side of the supporting plate 970, and a driving motor 910 connected to a battery(not shown) is positioned in the first recess 950. A rotation axis 1040 is connected to the driving motor 910, and a first pulley

940 is connected to the upper portion of the axis. A second recess 990 is formed on the other side of the supporting plate 970, a second pulley 1010 is installed in the second recess and rotated by the pulley 940 and a belt 1000. A number of rollers 1020 are installed between the first recess 950 and the second recess 990 in the supporting plate, and a belt-transferring groove 960 is formed in order for the belt 1000 to be transferred between the rollers 1020. A rubber brush 930 to be in contact with the curved surface of the front cover 710 of the helmet 700 is coupled to the front side of the belt 1000 positioned in the belt transferring groove 960 by a supporting bar 1030 fixed on the belt. A receiving sensor C is installed on a side of the driving motor 910 and is operated by a signal from a button on the handle to control the driving motor 910 for driving the rubber brush 930 in multi-step. The operation and effect of the present invention is as follows. As shown in Fig. 7 - Fig. 9, the battery 890 in the driving part 870 for opening/closing the front cover 700 supplies an electric power to the driving motor 880 and the driving motor 880 rotates the ball screw 850 through the decelerator 900, when the front cover 710 of the helmet 700 is automatically opened/closed by a signal from the radio transmitting part 100. The operation of the present invention in connection with the buttons is as follows. When the front cover automatic/manual button 200 on the handle for toggling an automatic state and a manual state is set to the automatic state to open/close the front cover, the front cover is opened or closed depending on the speed detected by the speed detecting part 120. For example, if 5 km/h is a reference value, the front cover is automatically opened when the speed is over 5 km/h, and the front cover is automatically closed when the speed is under 5 km/h. It is also possible to operate the front cover of the helmet by the front cover-opening button 230 capable of opening the front cover manually and the front cover-closing button 240 capable of closing the front cover manually. The front cover automatic/manual button 220 does not affect the opening/closing of the front cover. Even though, the front cover automatic/manual button 220 is set to the automatic state, it is possible to open the front cover manually by the front cover opening button 230 and the front cover-closing button

240. When the ball screw 850 is rotated, the nut 860 engaged with the ball screw

850 is moved up and down together with the going up and down part 820 having the friction member 830 coupling the nut and the part. The wire 720, its one end connected the supporting part 840, performs a going up and down operation by the moving up and down operation of the part 820. The part 820 can be shaped as rectangular and move up and down with the nut 860. When the wire 720 connected to the supporting part 840 performs the going up and down operation through the going up and down operation of the part 820 together with the nut 860, the front cover 710 is opened/closed by the going up and down operation of the wire 720 because the other end of the wire 720 is connected to the hinge part 750 on the upper end of the front cover 710 through the fixing part 740 on the helmet 700. The circumference of the wire 720, which is connected to the supporting part 840 for opening/closing the front cover 710 is surrounded by the tube 760 made of a relatively hardened material, thereby the going up and down operation of the wire 720 being smoothed. The tube 760 prevents the wire 720 from being damaged. Further, the going up and down part 820 having the driving motor 880, the ball screw 850 and the nut 860 engaged with the screw therein, and a vertical case 810 installed vertically on the outside of the part 820 can be easily mounted on one side of the helmet 700 by a cover 770. Therefore, by the going up and down operation of the part 820 by means of the operation of the driving motor 880 operated forwardly or reversely by the signal from the radio receiving part C, the wire 720 performs the going up and down operation to easily open/close the front cover 710 and a noise generated from the opening/closing of the front cover 710 can be minimized. As shown in Fig. 10 - Fig. 12, when the front cover 710 of the helmet 700 is automatically wiped by using the rubber brush 930, the driving motor 910 installed in the first recess 950 on a side of the supporting plate 970, said plate having the curved surface formed with the cover-engaging groove 980 engaged with the upper end of the front cover 710, receives a signal generated from the operation of the buttons on the handle of motorcycle through the radio receiving part C to be operated. Describing in detail, the front cover brush on/off button 250 on the handle is off if its operation is not needed. The brush can be operated by various buttons. The buttons are the manual front cover brush button 260 for operating the front cover brush only a time, the front cover brush interval button 270 for operating the front cover brush intermittently and with a predetermined time interval(for example, 10 time/1 minute), the front cover brush slow button 280 for operating the front cover brush in slow, and the front cover brush quick button 290 for operating the front cover brush quickly. The manual front cover brush button 260 for operating the front cover brush only a time can be operated only when the front cover brush on/off button 250 on the handle, which determines the operation of the brush, is off. The driving motor 940 is driven by a battery(not shown) to rotate the pulley 940 connected the rotation axis 1040. By the rotation of the pulley 940, the pulley 1010 can be rotated with the pulley 940 as the pulley 1010 in the second recess 990 formed on the supporting plate 970 is coupled to the pulley 940 through the belt 1000. As a number of rollers 1020 are installed between the first recess 950 and the second recess 990 and the belt transferring groove 960 is formed in order for the belt to be transferred between the rollers 1020 in the supporting plate 970, the belt 1000 in the groove 960 can be moved right or left by the forward or reverse rotation of the motor 910. Therefore, the rubber brush 930 connected to the belt 1000 through the supporting bar 1030 can also wipes the front cover 710 of the helmet 700 as the brush 930 is moved by the movement of the belt 1000. The rubber brush 930 is constructed to come into contacted tightly with the curved surface of the front cover 710. As the driving motor 910 is controlled in multi-steps, the rubber brush 930 is operated fast or slow according to the selection of the buttons on the handle.

Industrial Applicability According to the present invention, there is a great effect such that the driving motor in a helmet for motorcycle is operated by a signal from the radio switch, and the front cover of the helmet can be automatically and easily opened/closed by the ball screw connected to the driving motor and the hinge part to prevent a possible accident due to careless drive. And the front cover can be opened/closed automatically, the front cover can be opened/closed manually if needed, a noise generated from the opening/closing operation of the front cover can be minimized, the fabrication and installation of the front cover opening/closing device can be performed easily, and a rubber brush connected a belt is in contact with tightly the front cover and can be moved right and left by controlling buttons on the handle, thereby obtaining a broad and clear field of vision and preventing an accident due to careless.
