Description
Technical Field
The utility model belongs to the technical field of the helmet, concretely relates to helmet defogging device.
Background
A motorcycle helmet is a head protection device for motorcycle drivers and passengers. The helmet mainly aims to protect the head of a rider when being impacted, prevent or reduce injury and even save the life of the rider, and meanwhile, the helmet is provided with a wind shielding lens for blocking strong wind blowing from the head to the face so as to avoid driving danger caused by the fact that eyes cannot be opened due to the strong wind. However, in cold weather, when a rider wears the helmet to go out, hot air exhaled from the nose easily forms water mist on the wind-blocking lens, so that the sight of the rider is greatly affected, and serious safety accidents are easily caused.
In order to eliminate water mist as much as possible and avoid safety accidents, the development of an intelligent defogging and antifogging device for a helmet is necessary, some existing defogging and antifogging devices for a helmet are brought into the market, for example, a special liquid medicine is used for soaking a lens for antifogging, or a design means is used for controlling the flowing direction of air in the helmet, and on the premise of ensuring the temperature in the helmet during riding in winter, water vapor in the helmet is rapidly pumped out of the helmet, so that the humidity in the helmet is reduced, and an antifogging effect is achieved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a helmet defogging device has solved the problem that the helmet defogging that exists is with high costs among the prior art.
The technical scheme adopted by the utility model is that the helmet defogging device comprises a helmet shell, wherein the helmet shell is movably connected with a windshield, the upper edge of the helmet shell, which is close to the windshield, is provided with a humidity sensor, the humidity sensor is electrically connected with a power supply, the power supply is electrically connected with a power switch, and the power switch is fixed on the helmet shell through a switch base; the humidity sensor is electrically connected with a motor driving device, the motor driving device is connected with a connecting rod device, the connecting rod device is connected with a defogging boneless brush, and the defogging boneless brush is in contact with the inner side of the windshield.
The utility model discloses a characteristics still lie in:
the number of the demisting boneless brushes is two.
The demisting boneless brush comprises a windshield wiper rubber strip, a boneless windshield wiper steel sheet, a windshield wiper sheath and a plastic piece.
The motor driving device is a low-power miniature direct current brushless motor driver.
The humidity sensor is a resistance-type humidity sensor.
The utility model has the advantages that: (1) in winter, the water mist on the helmet windshield can be detected, and the helmet windshield can be automatically wiped clean, so that the vision line of a rider is not obstructed, and the risk of accidents is reduced; (2) the sensor automatic defogging device is more intelligent and automated than the high cost and high consumption of defogging agents and the high skill level requirements for controlling air circulation.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a helmet defogging device, as shown in figure 1, comprising a helmet shell 1, wherein the helmet shell 1 is movably connected with a windshield 4, the upper edge of the helmet shell 1 close to the windshield 4 is provided with a humidity sensor 5, the humidity sensor 5 is electrically connected with a power supply 9, the power supply 9 is electrically connected with a power switch 2, and the power switch 2 is fixed on the helmet shell 1 through a switch base 8; the humidity sensor 5 is electrically connected with a motor driving device 3, the motor driving device 3 is connected with a connecting rod device 6, the connecting rod device 6 is connected with two demisting boneless brushes 7, and the demisting boneless brushes 7 are in contact with the inner side of the windshield 4.
The link device 6, as shown in fig. 3 and 4, can convert the curvilinear motion of the motor driving device 3 into a linear motion, and drive the defogging frameless brush 7 to move inside the windshield 4.
The motor driving device 3 is a low-power miniature direct current brushless motor driver, and is a motor which adopts a direct current power supply and realizes electronic commutation through the control of an external motor controller.
The wiper blades on the left side and the right side of the demisting boneless wiper 7 move in opposite directions in the same time, so that the influence of the wiper blade on the sight of people is reduced as much as possible, and the safety of the wiper blade in working is ensured.
