Detailed Description
The invention is further described with reference to the following figures and examples.
Referring to fig. 1 and 2, the micro-opening mechanism 3 of the present embodiment is disposed at a position where the lens 1 is coupled to the helmet shell 2, and referring to fig. 2 to 4, the micro-opening mechanism mainly includes: the lens comprises a limiting part 12 arranged on the lens 1, a rail 31, a slope 31c higher than the slightly-opened limiting position 31b on the surface of the rail 31, and a retaining mechanism 32, wherein the retaining mechanism 32 is used for applying force to the lens 1 to keep the limiting part 12 to generate pressure on the slightly-opened limiting position 31b, the limiting part 12 is kept limited by the slightly-opened limiting position 31b through the retaining mechanism 32 to keep the slightly-opened state of the lens 1, and when the lens 1 is continuously opened, the limiting part 12 moves on the slope 31c.
The term "ajar" as used above and hereinafter means that the lens 1 is turned upwards by a small angle relative to its closed position, such that the edge of the lens 1 creates a gap for air to flow through in the viewing window of the helmet, while still ensuring that the lens 1 is still protected from the eyes and surrounding face, and the angle of this turning includes, but is not limited to, less than 5 °, such as 1 °, 2 °, 3 °, etc., and in some cases may be 6 °, 7 °, 10 °, etc.
Referring to fig. 8, in the present embodiment, the position-limiting portion 12 is a rod, a side surface of the rod slides on the surface of the rail 31, the holding mechanism 32 holds the rod on the rail 31 by applying a force to the lens 1, the rod slides relative to the rail 31 during the rotation of the lens 1, and when the rod passes through the slight-open position 31b on the surface of the rail 31, the rod stays in the slight-open position 31b due to the force of the holding mechanism 32, thereby fixing the lens 1 at the slight-open position.
The shape of the track 31 is as shown in fig. 8 and 9, the track 31 sequentially has a closing limit position 31a from bottom to top, a slight opening limit position 31b is arranged above the closing limit position 31a, the slight opening limit position 31b is followed by the slope 31c, and the slope 31c is followed by the closing limit position 31a. When the lens 1 is opened, the stopper portion 12 enters the full open stopper position 31d from the closed stopper position 31a through the slight open stopper position 31b and over the slope 31c. One of the limit positions is a concave surface, the rod is limited by sliding along the rail 31 in the concave surface, referring to fig. 2 and 8, on the basis, a positioning convex part 313 is provided in a slightly open limit position 31b, a positioning concave part 121 is provided on the limit part 12, and when the limit part 12 is limited by the slightly open limit position 31b, the positioning convex part 313 and the positioning concave part 121 cooperate to realize the positioning of the limit part 12, thereby increasing the accuracy of the slightly open limit. In some embodiments, the slope 31c may further have one or more adjustment limiting positions, which on the one hand can provide the user with more opening angles of the lens 1, and on the other hand, the adjustment limiting positions can provide a damping feeling when the limiting portion 12 slides on the slope 31c, and like a gear joint, can improve the user experience and the high-grade feeling during adjustment. On the other hand, dividing the slope surface 31c into segments with different slopes can improve the stability of the lens 1 at the slight opening position, as shown in fig. 9, the slope surface 31c has a first slope segment for blocking the passing of the limiting portion 12 and a second slope segment for facilitating the passing of the limiting portion 12, the first slope segment is at a side close to the slight opening limiting position 31b and is used for blocking the passing of the limiting portion 12, when the lens 1 needs to be further opened from the slight opening, the limiting portion 12 needs to perform "climbing" on the first slope segment, in the process, the pressure of the limiting portion 12 on the first slope segment is increased, and a falling tendency for the limiting portion 12 to fall back to the slight opening limiting position 31b is provided, the magnitude of the slope can be adjusted according to the actual situation, the larger the slope is, the more external force needs to be applied when the lens 1 is further opened, and the stability of the lens 1 at the slight opening is also better, the smaller the slope, the less external force is required for adjustment, and the adjustment is smoother, while at the same time the stability of the lens 1 in the ajar position is gradually reduced. The second slope section 312 is designed between the first slope section 311 and the fully-opened limit position 31d, in order to facilitate the limit portion 12 to pass through the second slope section 312, the slope of the second slope section 312 can be generally gentle or negative angle, so as to reduce the external force required by adjustment, of course, the slope surface 31c can be divided into more slope sections, when the slope surface 31c is also provided with other adjustment limit positions, the slopes with the same or different slopes can be respectively designed between every two limit positions, so as to adjust the adjustment hand feeling and stability.
As shown in fig. 5, the holding mechanism 32 includes a base 322 and a rotating seat 321, the lens 1 is mounted on the rotating seat 321, the rotating seat 321 is matched with a corresponding shaft hole 3212 on the rotating seat 321 through a second rotating shaft 3221 on the base 322, so as to realize that the rotating seat 321 is rotatably mounted on the base 322, the rotating seat 321 drives the position-limiting portion 12 of the lens 1 to separate from or attach to the surface of the track 31 through rotation relative to the base 322, an elastic member is connected between the rotating seat 321 and the base 322, the elastic member acts on the rotating seat 321, so that the rotating seat 321 drives the position-limiting portion 12 to attach to the surface of the track 31 and generate a certain pressure, referring to fig. 6, the rotating seat 321 has a first connecting portion 3213, the base has a second connecting portion 3222, and the elastic member is connected between the first connecting portion 3213 and the second connecting portion 3222, the resilient member is a spring 33. The track 31 of this embodiment sets up in one side of base 322, rotate the seat 321 and realize rotating through the coupling with base 322, it is close to or keeps away from through lens 1 and the connecting piece 12 that rotate its connection to rotate the seat 321 track 31, through external force (generally derive from the wearer) pulling lens 1 drive and rotate the seat 321 and rotate, the track 31 surface that spacing portion 12 left, thereby be convenient for lens 1's regulation, after the regulation, the elastic component then is in rotating the seat 321 through the elastic force effect, so as to drive to get spacing portion 12 and paste in track 31 surface and produce certain pressure.
Further, the holding mechanism 32 can be directly used for connecting the lens 1 and the helmet shell 2, the holding mechanism 32 is fixed on two sides of the shell 2, the rotating seat 321 has a first rotating shaft 3211, two ends of the lens 1 have shaft sleeves 11 sleeved on the peripheries of the rotating shafts, the lens 1 can be rotatably sleeved on the first rotating shaft 3211 through the shaft sleeves 11, the shaft sleeves 11 rotate relative to the first rotating shaft 3211 in the opening and closing process of the lens 1, and the rail 31 and the limiting part 12 can be simultaneously arranged on two sides or one side of the helmet.
When the helmet is worn, the lens 1 is pushed upwards to slightly open, the limiting part 12 enters the slightly-opened limiting position 31b, and due to the action of the spring 33 in the retaining mechanism 32, the limiting part 12 is kept limited by the slightly-opened limiting position 31b, so that a stable gap is generated between the lens 1 and a window of the helmet, and the lens 1 is prevented from being fogged.
