Example Embodiment

[0063] Example 1

[0064] figure 1 It is a schematic perspective view of the structure of the helmet in the present invention. like figure 1 As shown, the helmet includes a helmet shell 1 . The helmet shell 1 is provided with a transparent window 2 . A lens 3 is arranged inside the helmet shell 1, and only a part of the lens 3 is shown. One end of the lens 3 is connected with the helmet lens position adjustment device 4 .

[0065] The helmet lens position adjustment device 4 includes a saddle-shaped pusher 6 . The saddle-shaped pusher 6 is arranged on the outer surface of the helmet shell 1 and can move linearly along the outer surface of the helmet shell 1 . Fader 6 is an operating part. When the fader 6 moves linearly, the linear motion of the fader 6 can be converted into a driving force for driving the lens 3 to rotate, so as to drive the lens 3 to rotate. The lens 3 can be positioned between the transparent window 2 and the wearer's eyes after it can be rotated co...

Example Embodiment

[0082] Example 2

[0083] On the basis of Embodiment 1, a compression spring (not shown in the figure) is provided in the first sleeve 74 . The compression spring is located between the elastic piece 513 and the lower cover 52 , and is located in the movement direction of the elastic piece 513 when it is compressed. Adding a compression spring can buffer the pressure of the cylindrical button 53 on the elastic piece 513, prevent the elastic fatigue of the elastic piece 513 after being pressed many times, and prevent the elastic piece 513 from breaking. At the same time, the compression spring can provide an elastic force to the elastic piece 513 , so that the hook 5131 can be better inserted into the hanging groove 66 , increasing the restricting force of the hook 5131 on the pusher 6 .

Abstract

The invention discloses a helmet lens position adjustment device, which is characterized by comprising an operation element and a linear movement rotation converting device, wherein the linear movement rotation converting device converts the linear movement of the operation element into rotary driving power and comprises a rack and a circular gear; the rack is connected with the operation element; and the circular gear is meshed with the rack. The helmet of the invention is additionally provided with the lens position adjustment device, thereby conveniently adjusting the position of the lens.When the sunlight is strong, the device can slightly push the operation element to adjust the lens so as to shade the eyes to prevent the sunlight from directly irradiating the eyes and can prevent ultraviolet rays; and if no lens is needed for shading, only a column button is pressed, then the lens can be automatically returned to the primary position, and the sight line of a person wearing the helmet is clear. Only one helmet provided in the invention is suitable for various conditions and occasions.

Description

technical field [0001] The invention relates to a helmet lens position adjustment device and a helmet. Background technique [0002] The helmets used in the prior art have full helmets and half helmets. Generally, a transparent cover is arranged on the half helmet, and the transparent cover is rotatably arranged on the helmet shell. When the transparent cover is needed, turn the transparent cover to the face, which can be used to block sunlight and ultraviolet rays; it can also protect the driver's eyes from the wind. [0003] The shell of the full-face helmet is provided with a transparent window. The transparent window is generally fixedly installed on the helmet shell, and the position cannot be adjusted, and it is not easy to replace. The transparent window in the prior art generally adopts the good transparent material of light transmittance to make in order to avoid blocking the sight line of driver and passengers. However, one of the disadvantages of high light tr...
