Two of the purpose of this utility model is in order to overcome deficiency of the prior art, a kind of helmet with helmet goggles adjusting device simple in structure to be provided.
For realizing above purpose, the utility model is achieved through the following technical solutions:
The helmet is characterized in that, comprises housing and goggles, also comprises aforesaid helmet goggles adjusting device, and described goggles two ends are connected rotatably with the terminal pad of a helmet goggles adjusting device respectively; Described terminal pad drives described goggles and moves when moving; Described pedestal is installed on headpiece case.
The utility model is simplified the whole system structure by the syndeton optimal design of pedestal and terminal pad, avoids using complicated assembly.Due to movement that can the direct control terminal pad, thereby avoid causing motion not smooth due to friction or lever hole plug.
The utility model applies tractive force by the single line cable or thrust is come the motion of control connection dish.Such flexibility adapts to very limited application scenario, inner helmet space very much, prevents from causing because space is limited the motion of terminal pad to get clogged.Require emphasis, this strength can be thrust or tractive force, and perhaps both adopt simultaneously.
In the cooperation of pedestal and terminal pad, because terminal pad need to move around connector, therefore must consider minimum and maximum two extreme sport positions of connector motion.Simultaneously when the extreme sport position, must overcome the eyeglass deflection that causes owing to acting on pressure on eyeglass or elastic force.Adopt the torsion spring function that the redundancy of motion just is provided, guaranteed that fully eyeglass is opened to helmet peak position, the terminal pad motion can effectively move to extreme position.
The two ends of connector connect respectively pedestal and terminal pad, and by the first elasticity reset device, especially torsion spring provides the required power that resets, and so just guarantee that efficient of simple while of mounting structure is high again.
For simplifying being connected of pedestal and terminal pad, stud connector design becomes certain radian, thereby the two ends that guarantee connector can both rotate, thus drive terminal pad can front and back to the motion of introversion and extroversion.In order to limit and/or the motion amplitude of control connection dish, the terminal pad structure comprises the limited post of a projection, to guarantee the amplitude of the relative base motion of terminal pad.
For further optimal design, can control the operation of whole terminal pad by a kind of switch, guarantee simultaneously the terseness of whole mechanism.For example: a button of controlling cable can be installed on the helmet, conduct controlled pressure and/or mode of traction goes to terminal pad, by terminal pad, goggles be remained on simultaneously the position that needs.Helmet goggles adjusting device in the utility model can fit to the recess of headpiece case when making helmet glasses lens closed, guarantee the part of outstanding headpiece case.So just can so that helmet glasses lens not only satisfy the original function requirement, also can strengthen helmet aerodynamic quality simultaneously and promote helmet outward appearance aesthetical perception.Helmet glasses lens thickness of the present utility model is equal to the sunk part at the closed place of helmet glasses lens, outstanding headpiece case part when closed with the assurance eyeglass.When eyeglass was opened, the elasticity reset device in mirror-seat structure made eyeglass at first can eject the housing sunk part, then allowed eyeglass to rotate around axis, guaranteed that eyeglass opens the ear top that rear height surpasses the user.And eyeglass is when closing, and motion mode is opposite.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
To shown in Figure 6, the helmet goggles adjusting device 100 in the utility model comprises pedestal 60 and the movable terminal pad 10 of another one that is fixed on (not shown) on headpiece case as Fig. 1.Terminal pad 10 is connected with the eyeglass 90 of rotatable goggles, and the central portion 91 of a projection is arranged on eyeglass 90.Central portion 91 edges snap together with terminal pad 10, can rotate with respect to terminal pad 10 again simultaneously.Also comprise simultaneously a snap close 92 and be used for fixing len 90, prevent that eyeglass 90 and terminal pad 10 from coming off.
Pedestal 60, the hinge 30 of terminal pad 10 and two rigidity is to link together by the first axle 31 and the second axle 33 that passes the pan 32 on hinge 30.The pan 32 of hinge 30 first ends is positioned at the first groove 62 of pedestal 60; The pan 32 of hinge 30 second ends is positioned at the second groove 12 of terminal pad 10.Use two the first parallel axles 31 and be connected axle 33 and hinge 30 be connected with pedestal with terminal pad 10 be connected rotatably respectively.The first axle 31 passes the pan 32 of hinge 30 first ends, and hinge 30 is connected rotatably with pedestal 60; The second axle 32 passes the pan 32 of hinge 30 second ends, and hinge 30 is connected rotatably with terminal pad 10.Connect terminal pad 10 pedestal 60 motions relatively by two hinges 30.
The interposition of terminal pad 10 is equipped with a storage tank 14 that lengthens.Fix a spring function body storage tank 14 is interior, for example Compress Spring 40.The storage tank 14 that lengthens is a little longer a little than compression spring 40, guarantees that so that enough spaces to be provided Compress Spring 40 can draw high extension.One end of Compress Spring 40 withstands on an end of storage tank 14, and the other end uses the end cap 82 of a cable 80 passing Compress Spring 40 to push down, and the compression of Compress Spring 40 or the cable 80 that extends through the through hole 18 that passes on terminal pad 10 are controlled.Cable 80 can be directly connected on button being fixed on the helmet or controlling organization (showing in Fig. 1 and Fig. 2), for example: button or controlling organization can be assemblied in helmet bottom opening position (not shown), in order to adjust the tension force on cable 80.In order to facilitate the slip of cable 80, designed an end opening and be 66 sleeve pipe 64 on pedestal 60.Sleeve pipe 64 positions are corresponding with through hole 18 positions.
Hinge 30 guarantees spring function by one or more torsion springs 50 all, controls simultaneously the motion mode of hinge 30 by torsion spring 50.
Hinge 30 can move with respect to pedestal 60, and hinge 30 is arcuate shape.When hinge 30 sweeps moved downward on earth towards pedestal 60, terminal pad 10 was towards pedestal 60 motions (referring to Fig. 3 and 4), and guarantees to reach between them minimum range.When hinge 30 erects when reaching approximately perpendicular to pedestal 60, terminal pad 10 is higher than (seeing Fig. 4 and 6) on pedestal 60, and this moment, the distance between them reached maximum.Terminal pad 10 not only can move (Fig. 5, arrow G direction) relative to pedestal 60 in the vertical direction, and simultaneously relatively pedestal 60 is done the displacement (Fig. 5, arrow F direction) of horizontal line.
As mentioned above, by the size and Orientation of the active force on the transmission device cable 80 in executing agency, control the position of mobile link dish 10.Control the button of cable 80 or controlling organization and be arranged on goggles adjusting device 100 belows, button or controlling organization pull down moving-wire cable 80, can pull terminal pad 10 to make it to move to and pedestal 60 position farthest towards the direction away from pedestal 60 by cable 80.
As shown in Figure 3, Figure 4, this moment, eyeglass 90 was positioned at closure state, namely was close to headpiece case.If pull cable 80, end cap 82 will be oppressed Compress Spring 40 so, and tethered sliding terminal pad 10 moves.Because the force direction of Compress Spring 40 and torsion spring 50 is opposite, can accurately effectively control the movement of hinge 30.After cable 80 was tightened, as shown in Figure 5, terminal pad 10 was positioned at apart from pedestal 60 position farthest.At terminal pad from state shown in Figure 3 during to state-transition shown in Figure 5, eyeglass 90 and terminal pad 10 can be simultaneously towards two mutually perpendicular directions (arrow F1 direction shown in Figure 3 and arrow G direction) motion, that is to say eyeglass 90 and terminal pad 10 can be simultaneously to helmet front side to moving with headpiece case both sides outward direction.At state shown in Figure 5, eyeglass 90 no longer is close to headpiece case, and eyeglass 90 has certain distance with headpiece case, thereby guarantees that eyeglass 90 with respect to terminal pad 10 rotation the time, can not be subject to the obstruction of other parts of headpiece case.
As Fig. 5, shown in Figure 6, if loosen to greatest extent at this moment cable 80, end cap 82 pressure can diminish.Even without Compress Spring 40, the torsion of torsion spring 50 also can twist hinge 30, thereby drives terminal pad 10 motions.Terminal pad 10 drives eyeglass 90 and moves to the position minimum with pedestal 60 distances towards pedestal 60.After cable 80 loosened, as shown in Figure 3, terminal pad 10 was positioned at the position nearest apart from pedestal 60.At terminal pad from state shown in Figure 5 during to state-transition shown in Figure 3, eyeglass 90 and terminal pad 10 can be simultaneously towards two mutually perpendicular directions (seeing arrow F2 direction and arrow G direction in Fig. 5) motion, that is to say that eyeglass 90 and terminal pad 10 can be simultaneously move towards headpiece case direction and headpiece case both sides inward direction.At state shown in Figure 3, eyeglass 90 is close to headpiece case, is fastened on headpiece case.
Note that elastic fluid or spring 40, (both get final product by one) can be assemblied between terminal pad 10 and execution unit according to mode described above.Compress Spring 40 is main in order to keep the tension force to cable 80, also makes up different piece due to the deformation that causes as factors such as aging or thermal expansions by its elastic module simultaneously.Another benefit that Compress Spring 40 can also bring is when making eyeglass 90 closed, can settle at one go and return to the position of tightly fitting with headpiece case.Concrete operation method is when eyeglass 90 opens to helmet top, and the user is by being applied to the pulling force compressing Compress Spring 40 on cable 80, and such operation can not drive eyeglass 90 and be subjected to displacement, and just reduces eyeglass with respect to the height of user face.Be lowered into face the place ahead of user when eyeglass rotation, when perhaps being placed into the eyeglass closing position, the elastic force of Compress Spring 40 can be automatically pulls to the headpiece case center to eyeglass, makes eyeglass tightly fit with headpiece case.Therefore, the user can at any time adjust trigger mechanism, and no matter eyeglass 90 is in is being opened the position or backing into the closed position, can guarantee that eyeglass can tightly fit on headpiece case, no longer protrudes from headpiece case.So just avoid helmet glasses lens to adjust trigger mechanism before closing, make the user namely use a hand to do such easy steps and just can shut easily helmet glasses lens, such design also provides the advantage that ensures driving safety concerning the user.
Compress Spring 40 is normally used is compression stress, the torsion of the expansion that torsion spring 50 provides, and the effect of these two kinds of active forces is opposite.When selecting for two kinds of elastomers, Compress Spring 40 decides its coefficient of elasticity by the corresponding situation of load, but the rotation of the elastic constant of torsion spring 50 preferably can be slightly larger than Compress Spring 40, there is no obvious advantage like this with regard to the relative torsion spring 50 of active force that has guaranteed Compress Spring 40.
As previously mentioned, terminal pad 10 can move back and forth around the first axle 31 that passes hinge 30.It is this that the motion of certain surplus is arranged is very useful because its allow can autoregulation power thereon in eyeglass 90 moving process.The scope of this effect surplus is again that the limited post 16 below terminal pad 10 passes through to determine with the gathering sill acting in conjunction between two banking stops 68 on pedestal 60 when coordinating.To pedestal 60 motion the time (namely eyeglass closing course), limited post 16 moves along gathering sill when terminal pad 10, until move to (see figure 1) in the groove 70 of gathering sill one end.
Embodiment in the utility model only is used for the utility model is described, and does not consist of the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
