Description

Technical Field

[0001] The utility model relates to a helmet wiper with a detachable helmet lens, and relates to the technical field of rainproofing of safety helmets. Background Art

[0002] When the helmet is used in rainy and snowy days, the rain and snow hitting the face mask of the driver's helmet cannot be quickly discharged, affecting the driver's vision.

[0003] The existing publication number: 202020770833.7 discloses a helmet with a wiper. The device scrapes off the rain and snow on the windshield through the wiper on the helmet body, which can prevent the rain and snow from affecting the driver's vision when used on rainy and snowy days. However, in the actual life application of this patent, the limitations of various technologies such as motors, batteries, circuits, etc. in the existing market spare parts lead to the excessive size of the product, and there is no suitable solution to solve the installation problem on the helmet lens. If the helmet wiper in the patented technology is to be sold separately as a single product, it will encounter problems such as difficulty in installing the host, such as:

[0004] 1. There is no installation position for the helmet lens. Opening a mold to make a helmet lens will involve the different structures of helmet lenses on the market, which is costly and cannot be applied to helmets of different specifications. However, the helmet lens is made of plastic materials such as PC. Changing the structure or punching holes in the helmet lens will bring safety issues to the helmet lens. If strong glue or 3M adhesive is used, the user experience will be reduced, and there may even be problems such as inability to stick, troublesome sticking, and weak sticking. The installation position of the helmet wiper also involves the wiper's effect on scraping rain and snow. Once the user is not accurate enough in the installation position of the wiper, it will affect the use of the equipment.

The product is clamped on the lens through the interaction of the back clip 29 and the anti-skid pad 30 bonded to the rear shell 28. It is stable and convenient to disassemble and assemble. In order to prevent the helmet lens from being scratched, the back clip 29 can also be processed with a rubber coating process. When the user closes the helmet lens, the gap between the helmet lens and the helmet body is well pressed against the back clip 29, further increasing the safety of the product against falling.

[0026] Specifically, the wiper shaft 16 is installed inside the front housing 1 through a bearing 34, and a wiper mechanism is installed on the wiper shaft 16. The bearing 34 is installed inside the front housing 1. The bearing 34 and the wiper shaft 16 are combined and installed in the front housing 1 to solve the wear and damage of the wiper shaft 16 to the inside of the plastic panel 2 during use. A motor 18 is installed at the center position inside the front housing 1, and the output end of the motor 18 is fixedly connected to the axis of the wiper shaft 16. Batteries 26 are installed on both sides of the interior of the front housing 1, and a PCB light board 21 and a PCB main board 22 are provided inside the front housing 1. , PCB keypad 23 and limit switch 15, a switch mounting groove 32 for installing the limit switch 15 and a pressure plate 17 for fixing the limit switch 15 are provided in the front shell 1, and a bracket 20 for fixing the motor 18 is also provided in the front shell 1. After the limit switch 15 is installed in the switch mounting groove 32, the pressure plate 17 is pressed against the limit switch 15, and then the motor 18 is combined with the wiper center shaft 16 for installation. The motor 18 has a motor shaft, and a motor shaft mounting hole is designed in the wiper center shaft 16. After the two components are installed in coordination, the bracket 20 is pressed and installed on the motor 18 for stability. Among them, two batteries 26 are connected in series, and the batteries 26, the PCB light board 21, the PCB key board 23 are electrically connected to the PCB main board 22. The PCB light board 21, the PCB main board 22, and the PCB key board 23 are installed in the front shell 1, and the fixing part 24 is installed on the PCB key board 23 to prevent the key board from loosening. The battery 26 is installed in the front shell 1, and the battery 26 is boosted in series and a protection chip board is implanted in the battery 26. Then, the positive and negative lines are welded together with the PCB main board 22, and then the PCB light board 21 is welded to the PCB main board 22 with a signal line, and then the PCB key board 23 is welded to the PCB main board 22 with a signal line, and then the limit switch 15 is welded to the signal line and connected to the PCB The main board 22 is welded, and the purpose is to switch on and use the PCB main board 22 by long pressing the PCB button panel 23, and the light of the PCB light panel 21 can play the role of program control and power reminder. The PCB button panel 23 is used to drive the program control motor 18 to operate, and there is a contact structure designed on the wiper center axis 16. When the motor is running, it drives the wiper center axis 16 to touch the limit switch 15. Because after the limit switch 15 is welded to the PCB main board 22 through the signal line, the chip in the PCB main board 22 drives the motor 18 to accurately start the reverse after receiving the signal, and returns after touching the limit switch 15 again, and repeats the cycle, which solves the problem of inaccurate wiper angle caused by the program control motor and realizes precise control of the angle of the wiper arm 4.Due to the shortcomings of 3V motors on the market and various problems, the product volume cannot be reduced, so the motor 18 selects a motor of 6V or above, but a 3V battery cannot drive a 6V motor. In order to solve this technical problem, the battery 26 is connected in series and boosted, and a protection board is implanted inside. At the same time, a protection chip is also provided in the PCB main board 22, which plays a double role of short circuit, explosion and fire protection. The two batteries 26 are distributed on both sides of the interior of the front shell 1 to solve the problem that batteries above 6V are large in size and cannot be matched with the product for micro-design. The installation positions of the above components are evenly distributed inside the product through design, which makes it extremely small and thin while solving the performance problem.
