Specific embodiment
The description of a step is done to the utility model below with reference to embodiment and attached drawing:
Embodiment one
As depicted in figs. 1 and 2, switching mechanism includes first driving device, the second driving device, base and mounting rack.Its
In, base includes seat arm 41 and pedestal 42, mounting rack include transverse arm 61 and mounting rod 62, the transverse arm 61 and base of mounting rack
Two seat arms 41 be fixedly connected into triangle, pedestal 42 is fixedly connected between two seat arms 41.Mounting rod 62 and transverse arm
61 are fixedly connected, and mounting rod 62 is mutually connected vertically with transverse arm 61.
First driving device includes the first cylinder 11, linking arm 12 and connecting rod 13.First cylinder 11 is fixed on the seat of base
On body 42, the piston rod 22 of one end of linking arm 12 and the first cylinder 11 is hinged, and the middle part of linking arm 12 and base pass through main hinge
Contact carries out hingedly, linking arm 12 being enable to be rotated around main hinge joint.The other end and connecting rod 13 of linking arm 12 are hinged, starting
The first cylinder 11 in first driving device is logical to allow piston rod 22 to push or pull on linking arm 12 to be turned at main hinge joint
It is dynamic, so that connecting rod 13 be driven to move.Since connecting rod 13 and hatch door 3 are hinged, when the first cylinder 11 drives connecting rod 13 to move,
Connecting rod 13 will drive hatch door 3 and be rotated at main hinge joint, to complete the first step rotation of hatch door 3.The first step of hatch door 3
After the completion of rotation, the second step of hatch door 3 is driven to rotate by the second driving device.
Second driving device includes the second cylinder 21, piston rod 22, support rod 24 and grabs wrist 23, is pacified in the pedestal 42 of base
Equipped with shaft 5, shaft 5 is even mounted on base by bearing, and shaft 5 is rotated in base.Second cylinder 21 is solid
It is scheduled on mounting rack, grabs wrist 23 and be fixed on support rod 24, piston rod 22 and grab that wrist 23 is hinged, so that the second cylinder 21
Piston rod 22 and support rod 24 indirectly carry out hinged.And one end of support rod 24 and shaft 5 are hinged, the other end of support rod 24
It is hinged with hatch door 3.Starting the second cylinder 21 allows the piston rod 22 of the second cylinder 21 to push or pull on support rod 24 by grabbing wrist 23
5 rotation around the shaft, so that hatch door 3 be driven to rotate.
In the present embodiment, when opening hatch door 3, first driving device is first enabled, rotates hatch door 3 around main hinge joint,
Hatch door 3 can be rotated around the circular arc of relatively large radius at this time, so that the motion profile of hatch door 3 be made to get around the component in hatch door 3.The
After one driving device allows hatch door 3 to turn an angle, then the second driving device is enabled, rotates hatch door 35 around the shaft, this
When hatch door 3 can be rotated around the circular arc of small radii, so that the motion profile of hatch door 3 be made to get around the component outside hatch door 3.It closes
When hatch door 3, operating process and opening hatch door 3 are exactly the opposite, start the second driving device before this, and make hatch door 3 around small radii
Circular arc carries out rotation gathering, after collapsing to certain angle, then enables first driving device, makes hatch door 3 around the circle of relatively large radius
Arc is rotated, and hatch door 3 is closed completely.
It will be apparent that several improvement or modification made should all regard under the premise of not departing from principle described in the utility model
For the protection scope of the utility model.
