Parcel tray any one lid 201 from start to open to during being turned to some position (such as Figure 14 b institutes
Show), with the rotation of the lid gear 202 on the lid 201, drive the input gear 4 in a set of linkage unit to rotate (specific
For, in the present embodiment, the input gear 4 positioned at left side rotates counterclockwise, and the input gear 4 positioned at right side turns clockwise
It is dynamic), because input gear 4 with the disk 3 that links keeps synchronous in the presence of pointer trundle 521, therefore in the set linkage unit
Linkage disk 3 also begin to rotate, and because the linkage disk 3 of left and right two is intermeshed, therefore, the rotation of a linkage disk 3 will
The linkage disk 3 in another set of linkage unit is driven to rotate, from there through the linkage disk 3 and input gear in another set of linkage unit
4 synchronization action, drive another lid 201 while open, so that it is guaranteed that synchronism when two lids 201 are opened, Jin Erbao
Demonstrate,prove aesthetic quality.In the process, pointer trundle 521 rotates under the drive of input gear 4, and it is in linkage disk 3 and defeated
The position entered on gear 4 is constant, i.e. one end of pointer trundle 521 passes through the second of the rectangular through-hole 43 of input gear 4 all the time
Starting point 431 is against at the first starting point 333 of the L-shaped groove 33 of linkage disk 3, and the other end of pointer trundle 521 is then in inner side
The grade of bearing pin 12 radius in the crescent cavity H of support 2 around outrigger 1 moves, until the pointer trundle 521 is another
End touches the arc shaped blade 221 for defining crescent cavity H, such as shown in Figure 12, positioned at the pointer of the clutch discs 5 in left side
Trundle 521 is moved at F counterclockwise, so as to be formed at E as shown in Figure 12 to the track T11 at F.
The lid 201 of parcel tray continues to open until being turned to fully open state (such as 90 °) (as shown in figure 14 c)
During, input gear 4 is rotated further under the drive of lid gear 202.However, because pointer trundle 521 is by arc
The limitation of the shape of blade 221 so that the other end of pointer trundle 521 can only continue along the bending direction of arc shaped blade 221
It is mobile, such as shown in Figure 12, the pointer trundle 521 positioned at the clutch discs 5 in left side is moved at G (i.e. crescent moon counterclockwise
One end of shape cavity H closing), so as to be formed at F as shown in Figure 12 to the track T12 at G.In the process, due to
Pointer trundle 521 diminishes around the radius of gyration of bearing pin 12, and therefore, pointer trundle 521 is with input gear 4 and connection
While Moving plate 3 rotates, its one end also from the first starting point 333 (the second starting point 431 of rectangular through-hole 43) of L-shaped groove 33 along
First concave part 331 (rectangular through-hole 43) is moved radially to the flex point 334 of L-shaped groove 33 (the second terminal of rectangular through-hole 43
432), so as to forming track T21 as shown in Figure 13.In addition, in this moving process, due to linking, disk 3 exists with input gear 4
Synchronous axial system is remained in that in the presence of pointer trundle 521, therefore two lids 201 continue to keep synchronous unlatching until opening
To maximum open position.
In the reverse closing process of any one lid 201 of parcel tray (as shown in Figure 15 a-c), a set of linkage unit
In input gear 4 rotated backward under the drive of the lid gear 202 of the lid 301, so as to drive through its rectangular through-hole
43 pointer trundle 521 rotates backward.In the process, position of the pointer trundle 521 on input gear 4 is constant, i.e.
One end of pointer trundle 521 still through input gear 4 rectangular through-hole 43 the second terminal 432, and pointer trundle 521
Position on linkage disk 3 is then changed：Due to the effect of elastic washer 6 so that one end of pointer trundle 521 is all the time
It is bonded with linkage disk 3, therefore, with the rotation of input gear 4, the L-shaped groove of one end of pointer trundle 521 from linkage disk 3
33 flex point 334 is moved towards First terminal point 335 until being moved on the inner face 32 of linkage disk 3, until lid 201 closes completely
When closing, one end of pointer trundle 521 again moves into the first of adjacent L-shaped groove 33 in the presence of elastic washer 6
At point 333, so as to form track T22 as shown in Figure 13, and now the other end of pointer trundle 521 is then in medial cradle
Around the grade of bearing pin 12 radius (radius size with consistent on last stage) mobile, example of outrigger 1 in 2 crescent cavity H
As shown in Figure 12, it (is branch at I that the pointer trundle 521 positioned at the clutch discs 5 in left side is moved through at I clockwise at G
The periphery wall of dagger 21 and the connecting place of arc shaped blade 221, pointer trundle 521 is after at the I, due to support column 21
The radius of periphery wall is different from the radius of circle where arc shaped blade 221, and therefore, the radius of gyration of pointer trundle 521 occurs again
Change, so that one end of pointer trundle 521 can be moved at the first starting point 333 of adjacent L-shaped groove 33) until moving
Move at E, so as to be formed at G as shown in Figure 12 to the track T13 at E.Due in this process, pointer trundle 521
One end removes L-shaped groove 33, therefore linkage disk 3 can not be driven to rotate, and in other words, input gear 4 can not be synchronous with linkage disk 3
Rotate, so that also remains stationary, i.e. two sets of linkage units can not link the linkage disk 3 in another set of linkage unit.Thus it is
It can be achieved to completely close one of lid 201 of parcel tray, and keep another lid 201 motionless (as shown in fig. 15 c),
So as to realize the effect that can independently close any one lid, and then improve and use the free degree.To close another lid
201, its motion process is same as above (here is omitted).
By taking the completely closed state of left side lid 201 shown in Figure 15 c as an example, if now reopening the left side lid
201, then after being completely closed due to the left side lid 201, the pointer trundle 521 of the clutch discs 5 in left side is located at corresponding to it
One end is again in the first starting point 333 of L-shaped groove 33, and therefore, the opening procedure of the left side lid 201 is as described above.This
When, although with the unlatching of the left side lid 201, drive the linkage disk 3 positioned at left side to rotate counterclockwise, and the connection on the left of this
Moving plate 3 has driven the linkage disk 3 on right side to rotate clockwise again, is located at right side but because right cap body 201 is motionless, corresponding to it
Input gear 4 and the pointer trundles 521 of clutch discs 5 remain stationary as, with rotating clockwise for the linkage disk 3, make
The one end for obtaining pointer trundle 521 gradually removes L-shaped groove 33 from the flex point 334 of a L-shaped groove 33 of linkage disk 3 and fallen into
(it can be understood at the flex point 334 of adjacent L-shaped groove 33 with reference to Figure 13).As can be seen here, after left side lid 201 reopens,
The independent closing of right side lid 201 is not interfered with yet.It should be understood that only after both sides lid 201 is turned off, then again
During opening cover 201, it can just cause two lids 201 are synchronous again to open.
