With continued reference to fig. 5, in particular, the normally closed connecting assembly 30 further includes a fixing member 90, and the limit stop 50 is disposed on the fixing member 90.
The operation of the helmet 10 with normally closed goggles will now be described (see also fig. 1, 2, 4, 5 and 6):
after the connector 70 is fixed with the wind screen 40, the connector 70 is connected with the helmet body 20; the specific operation mode is that the connecting piece 70 is clamped into the helmet body 20; in the process that the connecting member 70 is snapped into the helmet body 20, the connecting member 70 is smoothly snapped into the helmet body 20 due to the guiding function of the inclined guiding surface 740;
in addition, because the connecting piece 70 is an elastic piece, and the clamping portion 720 of the connecting piece 70 is provided with a plurality of gaps 750, the plurality of gaps 750 are distributed in an annular array by taking the central axis of the clamping portion 720 as the center, so that the clamping portion 720 is uniformly deformed in the process of clamping the connecting piece 70 into the helmet body 20, and the plurality of gaps 750 provide enough deformation space for the deformation of the clamping portion 720, so that the process of clamping the connecting piece 70 into the helmet body 20 is smoother, the stability after clamping is better, and the connecting piece 70 cannot be separated from the helmet body 20;
when the wearer needs to open the wind screen 40, the wearer pulls the wind screen 40 in the opening direction; the windscreen 40 is pulled in the opening direction, and simultaneously the windscreen 40 drives the connecting piece 70 to rotate along the opening direction, so that the adjusting part 710 is driven to rotate along the opening direction; in the process, the pressing force of one side of the adjusting part 710 on the reset elastic sheet 60 is increased continuously, so that the reset elastic sheet 60 is deformed continuously, and the other side of the adjusting part 710 is closed to the limit baffle 50 continuously; when the other side of the adjusting part 710 is pressed against the limit position baffle 50, the adjusting part 710 reaches the limit position in the opening direction, that is, the windscreen 40 is opened to the limit position at this time;
when the wearer no longer needs to open the goggles 40, the goggles 40 are loosened; when the wearer loosens the wind-blocking glass 40, the reset elastic sheet 60 resets itself, and pressure is applied to one side of the adjusting part 710 in the resetting process of the reset elastic sheet 60, so that the adjusting part 710 rotates in the direction opposite to the opening direction, the connecting piece 70 is driven to rotate in the direction opposite to the opening direction, the wind-blocking glass 40 is indirectly driven to rotate in the direction opposite to the opening direction, and the automatic closing of the wind-blocking glass 40 is finally realized; i.e. the closing of the windscreen 40 is achieved; when the adjusting part 710 rotates in the direction opposite to the opening direction, the other side of the adjusting part 710 is separated from the limit-position fence 50.
When the helmet 10 with the normally closed type wind shield glasses is used, the wind shield glasses 40 are in a normally closed type, and when a wearer needs to open the wind shield glasses 40, the wearer pulls the wind shield glasses 40; when the wearer releases the windscreen 40, the windscreen 40 returns to the closed position by the normally closed connecting assembly 30.
It should be noted that the reset elastic sheet 60 is disposed on the supporting member 80, and the supporting member 80 supports and fixes the reset elastic sheet 60. It should be further noted that the limit baffle 50 is disposed on the fixing member 90, and the fixing member 90 supports and fixes the limit baffle 50.
In addition, the helmet among the prior art is in order to realize the protection to wearer's head and face, and is poor to head and face's implementation comprehensive, rigid package mode gas permeability, and when the wearer dressed the helmet, the inside air of helmet was not enough circulated, and the wearer can not breathe fresh air, therefore feels uncomfortable easily. This is also why many people are reluctant to wear helmets and also why some wearers prefer to have the goggles 40 open.
However, opening the goggles 40 presents a problem of incomplete protection for the wearer during use. For example, in the process of driving and taking a vehicle, on one hand, the wind shield 40 is opened to make sand, mosquitoes and other things easily blow into eyes and noses to cause discomfort for a wearer, and in the serious case, the safe driving of the vehicle is influenced, and traffic accidents are easily caused; on the other hand, the goggles 40 are opened so that the wind directly blows toward the wearer's face. Therefore, although the problem of ventilation of the breathing air is solved by opening the wind-blocking mirror 40, the rapid wind directly blows to the face of the wearer during the high-speed driving process of the vehicle, so that the wearer feels very uncomfortable, and the sand wind and mosquitoes are easy to blow into eyes, and in serious cases, traffic accidents are caused, so that the life safety of drivers and passengers is influenced.
Aiming at the problem of poor air permeability of the helmet in the prior art, the helmet 10 with the normally closed type wind-shield glasses is improved as follows, so that the helmet 10 with the normally closed type wind-shield glasses is good in air permeability, and a wearer can breathe fresh air outside the helmet 10 with the normally closed type wind-shield glasses; at the same time, the protective properties of the helmet 10 with normally closed goggles are not affected.
Referring to fig. 2, in particular, the helmet 10 with the normally closed type goggles further includes a ventilator 100 disposed on the helmet body 20, the ventilator 100 being disposed below the goggles 40. That is, the ventilator 100 is provided at the mouth and nose of the wearer after wearing the helmet 10 having the normally closed type goggles 40. As shown in fig. 2, the ventilator 100 is inserted through the helmet body 20.
Referring to fig. 12 and 13, in particular, the ventilator 100 includes: knob 200, valve 300, and seal 400. The knob 200 is provided with a plurality of protrusions 210, the valve 300 is provided with a plurality of grooves 310, and the plurality of protrusions 210 and the plurality of grooves 310 are in one-to-one correspondence and are matched. The sealing member 400 is provided with a switch post 410, and the valve 300 is provided with a switch guide groove 320, and the switch guide groove 320 extends from a top portion near the valve 300 to a bottom portion near the valve 300 in an inclined manner. The switch post 410 is snapped into the switch guide slot 320. The valve 300 is closely fitted to the sealing member 400 or separated from the sealing member 400. Specifically, the switch column 410 is a cylinder. The knob 200 is provided with a first through hole 330, the sealing member 400 is provided with a second through hole 420, and the first through hole 330 and the second through hole 420 cooperate to form a ventilation channel (not shown in the figure) which is communicated with the interior of the helmet body 20. It should be noted that the switch guide groove 320 of the valve 300 is not a smoothly inclined structure, but is inclined stepwise. Thus, the switch post 410 is less likely to slip or shake in the switch guide groove 320 during ventilation, thereby ensuring stability of the ventilator 100.
Referring to fig. 8, 9, 10 and 11, in particular, the ventilator 100 further includes a filter 500 and an outer cover 600, the filter 500 is sleeved on an inner side wall of the outer cover 600, the outer cover 600 has a plurality of air vents 610 on the side wall, and the valve 300 is connected to an inner top wall of the outer cover 600 through a spring 620.
Referring to fig. 12 and 13, in particular, the outer wall of the knob 200 has anti-slip ribs 220, and the anti-slip ribs 220 are distributed in an annular array around the center of the knob 200, so that the knob 200 is not easy to slip when rotated.
The ventilator 100 may be assembled in the following manner (see fig. 10, 11, 12 and 13):
assembling the sealing member 400 with the valve 300 such that the switch post 410 of the sealing member 400 is caught in the switch guide groove 320 of the valve 300;
assembling the valve 300 with the knob 200 such that the protrusions 210 of the sealing member 400 are snapped into the grooves 310 of the valve 300 in a one-to-one correspondence;
the filter is fitted over the inner sidewall of the outer cap 600.
Of course, when the ventilator 100 is assembled with the helmet body 20, the filter and the outer cap 600 are pressed against the outer sidewall of the helmet body 20. So that the air outside the helmet body 20 enters the ventilator 100 through the vent 610, and the air outside the helmet body 20 enters the ventilator 100 and is first filtered through the filter, so that the air breathed by the wearer after wearing the helmet is kept clean.
The operation of the ventilator 100 will now be explained (please refer to fig. 10, 11, 12 and 13):
when the helmet does not need to be ventilated, the plurality of protrusions 210 of the knob 200 are correspondingly clamped into the plurality of grooves 310 of the valve 300 one by one, so that the knob 200 is rotated, and the valve 300 is driven to rotate by the knob 200, so that one end, close to the top of the valve 300, of the switch guide groove 320 of the valve 300 is close to the switch column 410 of the sealing element 400 until one end, close to the top of the valve 300, of the switch guide groove 320 of the valve 300 abuts against the switch column 410 of the sealing element 400; at this time, the valve 300 is tightly pressed against the sealing member 400, and the air passing through the air vent 610 and the filter 500 in sequence cannot enter the air vent channel, so that the ventilator 100 is closed;
when the helmet needs ventilation, the plurality of protrusions 210 of the knob 200 are correspondingly clamped into the plurality of grooves 310 of the valve 300 one by one, and the switch guide groove 320 of the valve 300 obliquely extends from the top part close to the valve 300 to the bottom part close to the valve 300; therefore, when the knob 200 is rotated, the knob 200 drives the valve 300 to rotate, such that the end of the switch guide groove 320 of the valve 300 close to the bottom of the valve 300 is close to the switch column 410 of the sealing member 400; the valve 300 is now separated from the seal 400; the air passing through the air vent 610 and the filter 500 in sequence enters the air vent channel from the separation gap between the valve 300 and the sealing member 400, thereby realizing air intake of the ventilator 100; of course, the gas exhaled by the wearer may also flow from the interior of the helmet to the exterior of the helmet through the ventilation channel, the separation gap between the valve 300 and the sealing member 400, the filter 500, and the ventilation port 610 in this order; thereby effecting ventilation of the helmet exterior and the helmet interior;
it should be noted that, according to the amount of ventilation desired by the wearer, the position of the switch column 410 of the sealing member 400 in the switch guiding groove 320 of the valve 300 can be adjusted by rotating the knob 200, so as to achieve the effect of adjusting the amount of ventilation; when the ventilation volume needs to be reduced, the switch column 410 of the sealing member 400 is towards one end close to the top of the valve 300 by rotating the knob 200, so that the gap between the valve 300 and the sealing member 400 becomes smaller; when the ventilation quantity needs to be increased, the switch column 410 of the sealing member 400 is enabled to be towards one end close to the bottom of the valve 300 by rotating the knob 200, so that the gap between the valve 300 and the sealing member 400 is enabled to be enlarged;
it should be noted that, since the air vent 610 of the outer cover 600 is opened at the side wall of the outer cover 600, the air outside the helmet entering the ventilator 100 is not directly blown in, but is turned to enter through the side wall of the outer cover 600; thus, the pressure of the air blown into the ventilator 100 against the front face of the ventilator 100 is greatly reduced;
furthermore, during venting, the gap between the valve 300 and the sealing member 400 is at the edge of the valve 300 and the sealing member 400, and the second through hole 420 of the sealing member 400 is opened at the middle of the sealing member 400; therefore, the air entering the inner part of the outer cap 600 needs to turn to the edge of the valve 300 and then to the second through hole 420 in the middle of the sealing member 400 at the edge of the sealing member 400 during entering the vent channel; therefore, the air needs to be turned for three times in the entering process from the outside of the helmet to the inside of the helmet, so that the speed of the air flowing into the helmet is greatly reduced, the air blown into the helmet is slow and mild, and the comfort of the helmet 10 with the normally-closed type wind-blocking glasses is greatly improved; when a wearer breathes, the wearer does not feel that air outside the helmet is directly blown to the mouth and the nose, and does not feel uncomfortable; and the ventilator 100 is only a small part compared with the helmet 10 with the normally closed type wind-shield glasses, and the ventilator 100 is arranged on the helmet body 20 in a penetrating way, so that the rigidity of the helmet body 20 is not affected, and the protective performance of the helmet 10 with the normally closed type wind-shield glasses is ensured.
In addition, it is also noted that the harm of harmful substances in the air to human body is an important aspect affecting human health due to the increasing environmental pollution. The ventilator 100 of the present invention filters air by the filter 500, and filters out harmful substances, sand, mosquitoes, etc., thereby ensuring clean, healthy, and safe air blown into the helmet. Referring to fig. 2 and 13 together, it should be noted that the filter 500 includes a filter frame 630 and a filter cotton 640 detachably disposed on the filter frame 630. The filter 500 is easy to install and disassemble. After a period of use, the filter element 500 may be removed for replacement or cleaning.
The ventilator 100 of the present invention greatly increases the comfort of a helmet 10 having normally closed goggles.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
