Description

Water wiping device for helmet

Technical Field

The application relates to the technical field of helmets, in particular to a water scraping device for a helmet.

Background

The helmet is a necessary protection tool for driving vehicles such as motorcycles or electric bicycles, and can resist shock and impact and protect the head of a driver when an accident occurs. The helmet is generally provided with transparent goggles at the face position, and in rainy days, rainwater is easy to attach to the goggles to influence the sight of a driver, particularly, under the condition of snowing, snow is easier to attach to the goggles, and is not easy to melt or the melting speed is lower after attachment, so that the influence on the sight is larger, and therefore, the water scraping device is provided for solving the attachment problem of the rainwater or the snow water through a physical means.

SUMMERY OF THE UTILITY MODEL

In order to solve the helmet goggles that prior art exists and adhere to rainwater or snow water influence problem, this application provides a water scraping device for helmet.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

a wiper device for a helmet, comprising: the water scraper is in contact fit with the surface of the helmet; the control box is connected with the water scraping knife in a transmission manner through a transmission mechanism and is positioned below the control box, and a driving mechanism for driving the water scraping knife to swing in a reciprocating manner is arranged in the control box; the mounting seat fixes the control box and is detachably and fixedly connected with the helmet.

The water wiping device in this scheme adopts physics means to scrape adnexed rainwater and snow water on the helmet goggles down, realizes scraping the holistic installation of water wiping device by being connected of mount pad and helmet, scrapes the action that the water sword scraped for the motion completion of helmet, and the control box installation and protection provide modules such as actuating mechanism of power and control for scraping the water sword motion. It should be noted that, transmission mechanism in this scheme is except transmitting power, still limits the position of water scraping sword in the below of control box, compares in the setting that water scraping sword and control box are in the coplanar, and the initial position of water scraping sword is more close to helmet surface in this scheme, and the control box protrusion is on the helmet, is favorable to saying that the frictional force between water scraping sword and the helmet maintains in appropriate scope. In addition, the water scraping knife is positioned below the control box, and the movement circle center of the water scraping knife is positioned at the joint of the transmission mechanism and the control box, namely the movement circle center is positioned on the control box, and the water scraping knife has a certain distance with the movement circle center, so that the movement track of the water scraping knife is in a fan-shaped ring shape in combination with the range covered by the length of the water scraping knife, and the fan-shaped ring is more suitable for the visual field range of people.

Furthermore, the transmission mechanism comprises a swing arm which is connected with the control box and swings to and fro around the axis of the connection part, and a connecting arm of which two ends are respectively connected with the water scraping knife and the swing arm to ensure that the water scraping knife and the swing arm move synchronously; the swing arm is the L type, control box and linking arm are connected with mutually perpendicular two cantilever ends in the swing arm respectively. The swing arm is set to be L-shaped, the position conversion that the water scraping knife is located below the control box is realized by means of the bending shape of the swing arm, in addition, the swing arm serves as a part directly connected with the driving mechanism, the shape of the L-shaped swing arm enables the driving mechanism and the water scraping knife to form a labor-consuming lever therebetween, the support arm connected with the control box in the swing arm is a shorter part in the lever, and the other support arm and the connecting arm of the swing arm are longer parts in the lever. The smaller angular displacement of the driving end can be converted into a larger movement range of the water scraping knife, namely, the rotation angle of one end of the swing arm connected with the control box is smaller, and the movement stroke of the water scraping knife is larger.

Furthermore, the connecting arm is bow-shaped, one side of the connecting arm, facing the water scraper, is connected with one end of the spring through the mounting hole, and the other end of the spring is connected with the swing arm. The arcuate connecting arm has a higher stability and the spring causes the connecting arm to apply a pressure to the wiper blade to press the wiper blade against the helmet so that the frictional force between the wiper blade and the helmet is maintained within a suitable range to wipe water from the helmet surface without affecting the movement of the wiper blade.

Further, the water scraper is bow-shaped, and includes that installation department and the fixed strip that removes that sets up in the installation department surface of dismantling the connection with the linking arm, remove the strip and suit with installation department and with helmet surface contact.

Furthermore, a switch control button and a rotating speed control button are arranged on the surface of the control box.

The beneficial effect of this application is: utilize reciprocal swing of water scraping knife to strike off attached water on helmet surface in this application, will scrape the water scraping knife through drive mechanism and set up in the below of control box, make the water scraping knife keep the certain distance with the motion centre of a circle that is located on the control box, form the annular motion coverage of fan, adaptation people's field of vision scope. In addition, the transmission mechanism can compensate the distance between the wiper blade and the surface of the helmet caused by the thickness of the control box, limit the initial position of the wiper blade to be closer to the surface of the helmet, and reduce the adjustment amount or eliminate the need for adjustment after the wiper device is installed on the helmet.
