DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figures 1 to 7 , the utility model provides a technical solution:

[0027] An electric rain and fog eliminating helmet comprises a helmet shell 1, goggles 2 and a rain and fog eliminating component 3, wherein the goggles 2 are movably mounted on the helmet shell 1, wherein:

[0028] The rain and fog eliminating component 3 includes a guide rail 31, a slider I 32, a slider II 33, an electromagnet 34, a connecting component 35, a wiper 36, a fog brush 37, and a driving component 38. The two guide rails 31 are respectively arranged in the fixing grooves inside the helmet shell 1 and are located at the upper and lower ends inside the helmet. The slider I 32 is installed on one of the guide rails 31, and the two sliders II 33 are installed on the other guide rail 31. The two sliders II 33 are independent of each other and can work separately. The two connecting components 35 are respectively arranged on the two sliders II 33, the wipers 36 and the fog brushes 37 are respectively arranged on the two connecting components 35, the two electromagnets 34 are arranged on both sides of the slider I 32, and the driving component 38 is arranged on the slider I 32 for driving the slider I 32 to move along the guide rail 31.

[0029] As a preferred embodiment, the connecting assembly 35 includes a fixed sleeve 351, a spring 352, a connecting rod 353, a permanent magnet 354 and a hydraulic rod 355. The fixed sleeve 351 is fixedly installed on the slider II 33. One end of the connecting rod 353 is movably installed inside the fixed sleeve 351, and the other end is fixed with a permanent magnet 354. The permanent magnet 354 and the electromagnet 34 will attract each other with the same sex when power is turned on. A spring 352 is provided between the connecting rod 353 and the fixed sleeve 351. When the spring 352 acts, the elastic force of the spring 352 can be utilized to restore the connecting rod 353 after being stretched. When the connecting rod 353 is stretched, one end of the connecting rod 353 inside the fixed sleeve 351 will not be pulled out of the fixed sleeve 351. The purpose of the connecting rod 353 being sleeved inside the fixed sleeve 351 is to enable the connecting rod 353 to drive the fixed sleeve 351 and the slider II 33 to move. At least two hydraulic rods 355 are arranged on the cylindrical surface of the connecting rod 353.

[0030] As a preferred embodiment, the driving assembly 38 includes a motor 381 and a wheel 382. At least one wheel 382 is rotatably mounted on the side of the slider I32 and contacts the guide rail 31. The motor 381 is fixedly mounted on the slider I32. The motor 381 is power-connected to the wheel 382. When the motor 381 is started, the wheel 382 can be driven to rotate along the guide rail 31. Under the friction between the wheel 382 and the guide rail 31, the slider I32 is driven to slide along the guide rail 31.

[0031] As a preferred embodiment, the windshield wiper 36 and the fog wiper 37 are fixed to the ends of the hydraulic rod 355 respectively arranged in different connecting assemblies 35 .

[0032] As a preferred embodiment, a wiper control button 11 is provided on the surface of the helmet shell 1, a fog wiper control button 12 is provided on the surface of the helmet shell 1, and a charging interface 13 is provided at the bottom of the helmet shell 1. The wiper control button 11 can control whether the electromagnet 34 in the connecting component 35 connected to the wiper 36 is energized, and the fog wiper control button 12 can control whether the electromagnet 34 in the connecting component 35 connected to the fog brush 37 is energized. The charging interface 13 is connected to the battery in the rain and fog elimination component 3, and the battery in the rain and fog elimination component 3 can be charged through the charging interface 13.

[0033] As a preferred embodiment, the windshield wiper control button 11 and the fog wiper control button 12 are actually relay switches, and controlling the switch of the electromagnet 34 is a conventional technical means, and its principle will not be elaborated here.

[0034] Working principle of the utility model: when there is water on the outer surface of the goggles 2, the wiper control button 11 can be pressed. At this time, the electromagnet 34 controlling the movement of the wiper 36 is energized to generate magnetic force, which attracts the permanent magnet 354 in the connecting assembly 35 connected to the wiper 36. Under the action of the two magnets, the connecting rod 353 is driven to move downward until the permanent magnet 354 and the electromagnet 34 are tightly fitted together. At this time, the spring 352 is stretched. When the wiper control button 11 is pressed, the motor 381 is started, driving the wheel 382 to rotate along the guide rail 31. Under the friction between the wheel 382 and the guide rail 31, the slider I32 is driven to slide along the guide rail 31. Under the combined action of the magnetic force and the friction between the two magnets, the movable slider II33 connected to the wiper 36 is driven to move synchronously along the guide rail 31 through the connecting rod 353 and the fixed sleeve 351. At this time, the wiper 36 also moves synchronously. At the same time, the length of the hydraulic rod 355 can be adjusted to adjust the distance between the wiper 36 and the goggles. The damping between the eyepiece 2 ensures the effect of water removal. At the same time, when the device moves to the other end of the guide rail 31, the motor 381 will reverse and then move back. Therefore, the wiper can move back and forth on the surface of the goggles, and then achieve the purpose of continuous water removal. When rain removal is not needed, just press the wiper control button again. At this time, the motor 381 no longer passes power, and the magnetic force of the electromagnet 34 disappears. The connecting rod 353 is reset under the action of the spring 352. At this time, there is no force between the slider I 32 and the slider II 33, and they are independent of each other. When defogging is required, press the fog wiper control button 12. The movement of the device is similar to that of the wiper 36, which will drive the fog brush 37 to defog the inner surface of the goggles 2. Since the fog brush 37 and the wiper 36 are independent of each other, they can be used for rain removal or defogging separately, and the two can also be used at the same time.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
