Following disclosure provides many different embodiments or example is used to realize different structure of the invention.In order to
Simplify disclosure of the invention, hereinafter the component of specific examples and setting are described.Certainly, they are merely examples, and
And it is not intended to limit the present invention.In addition, the present invention can in different examples repeat reference numerals and/or reference letter,
This repetition is for purposes of simplicity and clarity, itself not indicate between discussed various embodiments and/or setting
Relationship.In addition, the present invention provides various specific techniques and material example, but those of ordinary skill in the art can be with
Recognize the application of other techniques and/or the use of other materials.
Please refer to Fig. 1-Figure 11, the helicopter with door body switch protection structure that embodiment of the present invention provides, including
Cabin 1 and door body 2, cabin 1 offer inlet and outlet 11, and door body 2 movably closes inlet and outlet 11.Limit is provided in cabin 1
Part 12, for locating part 12 close to inlet and outlet 11, locating part 12 successively includes first from inlet and outlet 11 to the direction far from inlet and outlet 11
Confined planes 121 and the second confined planes 122, the first confined planes 121 connect the second confined planes 122, and the first confined planes 121 are in separate
The curved surface that 1 direction of cabin is arched upward, the second confined planes 122 are and the inclined plane in 1 surface of cabin.Door body 2 is close to the side of cabin 1
Be provided with the corresponding movable component 21 of locating part 12, door body 2 open up it is fluted, movable component 21 include pedestal 211 and activity
The fixing end 2121 of part 212, pedestal 211 and groove secure fit, movable part 212 is connected by torsional spring 213 and the rotation of pedestal 211
It connects, the rotation of the movable end 2122 of movable part 212 is provided with idler wheel 2123, and 212 self-retaining end 2121 of movable part is to movable end 2122
It is obliquely installed to the direction close to cabin 1, movable part 212 is formed with step structure 2124, and step structure 2124 and pedestal 211 are matched
It closes and movable part 212 is kept to stablize.
Big small door construction is arranged in helicopter of the invention, can use different size of inlet and outlet 11 according to different demands；Together
When, in 2 opening procedure of door body, movable component 21 and locating part 12 cooperate, and work as a buffer to door body 2, avoid door body 2 opened
Limit occurs to hit damage door body 2.
Specifically, when the door body 2 in present embodiment is in close state, door body 2 is not contacted with locating part 12, activity group
Part 21 is not also contacted with cabin 1, and corresponding locking mechanism is worked in coordination in cabin 1 and door body 2, and door body 2 is fixed in cabin 1
Closing inlet and outlet 11, in a state of nature, elastic deformation does not occur for torsional spring 213 at this time.During door body 2 is pulled open, door body 2
In motion process, the idler wheel 2123 on movable part 212 first touches the first confined planes 121 and along the radian of the first confined planes 121
It rolls, while movable part 212 is pressed against inside grooves by locating part 12 and shunk, and makes the torsion for connecting movable part 212 and pedestal 211
Elastic deformation occurs for spring 213, generates the elastic force for driving movable part 212 to reply to 1 direction of cabin, movable part 212 and locating part 12
Contact slows down the mobile speed of door body 2, so that door body 2 and cabin 1 be avoided to occur to contact firmly.Idler wheel 2123 rolls to the second limit
After on plane 122, torsional spring 213 is returned to reset condition.On condition that an external force is not applied, the second confined planes 122 resist activity
Part 212, and then door body 2 can not move, and guarantee the stabilization under 2 opening state of door body.
In some embodiments, locating part 12 and the setting of the interval of door body 2.
In this way, locating part 12 will not be interfered with the other structures in door body 2, Bu Huiying in 2 moving process of door body
Ring the fluency that door body 2 switchs.
In some embodiments, the second confined planes 122 resist idler wheel 2123, and limitation door body 2 is moved with respect to cabin 1.
Further, when needing to close door body 2, hatch door is firmly pulled, idler wheel 2123 and the second confined planes 122 is forced to be sent out
Raw rotation, and so that movable part 212 is climbed over locating part 12 to the bottom squeeze of groove movable part 212, release the limit to door body 2
System, allows door body 2 is smooth to close.
In some embodiments, movable end 2122 is compared to fixing end 2121 close to the outer surface of cabin 1.
In this way, movable end 2122 first contacts locating part 12 and makes to limit compared to fixing end 2121 in 2 moving process of door body
Part 12 is moved to bottom portion of groove direction, while making torsional spring 213 that elastic deformation occur, and provides elastic force for 12 homing of locating part,
Also the speed of the movement of door body 2 is slowed down, guarantees that soft contact occurs for door body 2 and cabin 1 when opening door body 2, avoids door body 2 from being damaged
Wound.
In some embodiments, movable part 212 is close to one end of movable end 2122 and the setting of the interval of pedestal 211.
In this way, movable part 212 be limited part 12 be pressed against bottom portion of groove rotation during, movable part 212 will not and base
Seat 211 interferes, and ensure that the smooth activity of movable part 212.
Specifically, movable part 212 does not interfere i.e. close to the track of one end of movable end 2122 rotation and pedestal 211
It can.
In some embodiments, the first guide rail 22 is provided in cabin 1, door body 2 is slidably arranged on the first guide rail 22.
In this way, being opened and closed convenient for door body 2.
In some embodiments, sub- inlet and outlet 11 are offered in door body 2, and the second guide rail 23 is provided on the inside of door body 2, son
Door body 24 is slidably arranged on the second guide rail 23.
In this way, the helicopter in present embodiment forms big small door construction, personnel can use gate according to actual needs
Or wicket.
Further, such as Figure 10 and Figure 11, cervical orifice of uterus body 24 and 1 corresponding position of cabin be provided with the locating part 12 at gate,
The identical position limiting structure 30 of 21 structure of movable component.Position limiting structure 30 makes wicket be slowed down in opening procedure, realizes soft connect
Touching avoids being damaged with the shock of cabin 1.Since position limiting structure 30 is identical with the limiting buffer structure working principle at gate,
This is repeated no more.
In conclusion the working principle of the helicopter with door body switch protection structure in present embodiment is substantially such as
Under:
When opening door body, door body is moved along the first guide rail, exposes inlet and outlet, in the movable component contact cabin in door body
Locating part, locating part withstand movable part, to slow down the speed of door body opening, avoid door body and cabin that hard contact occurs；
Idler wheel on movable part continues to roll along the first confined planes of locating part, while movable part is pressed to bottom portion of groove and turned
Dynamic, after idler wheel climbs over locating part, torsional spring drives movable part to resiliently return to home position, so that the second confined planes be made to resist activity
Part keeps door body static；
Meanwhile wicket is offered in door body, structure identical with above-mentioned enabling Buffer Unit structure is provided on wicket, with
It avoids in wicket opening procedure and hard contact occurs for door body, wicket and/or door body is avoided to damage, extend door body and/or cabin
Service life.
While embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that:
These embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principle of the present invention and objective and become
