The second unlocking assembly 28 preferably adopts an unlocking handle or an unlocking button, and in the embodiment, the unlocking handle is shown in the figure.
The working principle of the second locking mechanism 7 is as follows:
when the second locking mechanism 7 is in a locked state, the second gear 23 is simultaneously clamped in the third tooth groove 24 and the fourth tooth groove 25, at this time, the upper enclosure frame 4 and the lower enclosure frame 5 cannot rotate relatively, and the enclosure frame 2 is in an unfolded state.
When the second locking mechanism 7 needs to be unlocked, the second unlocking assembly 28 is operated, the second unlocking assembly 28 drives the locking member 8 to slide, the locking member 8 pushes the pushing block 27 to move axially through the inclined plane in a matched manner, the second gear 23 is driven to exit the third tooth groove 24 and be completely clamped into the fourth tooth groove 25, and the second locking mechanism 7 is unlocked.
As shown in fig. 2 to 4, 7 and 11, the upper surrounding frame 4, the lower surrounding frame 5 and the seat pocket connector 3 are rotatably pinned by a connecting pin 31, and the connecting pin 31 is fixedly disposed on the seat pocket connector 3.
Further, a first limiting mechanism 9 is arranged between the locking piece 8 of the second locking mechanism 7 and the upper enclosing frame 4 or the lower enclosing frame 5.
When the enclosure frame 2 is located at a working position, the first limiting mechanism 9 limits the locking piece 8, the locking piece 8 cannot perform unlocking movement, and the second locking mechanism 7 cannot be unlocked; when the enclosure frame 2 is located at the unlocking position, the first limiting mechanism 9 releases the limitation on the locking piece 8, and the locking piece 8 can perform unlocking movement, so that the unlocking of the second locking mechanism 7 is realized.
The first limiting mechanism 9 has the following specific structure: the first limiting mechanism 9 comprises a limiting piece 32 which is relatively matched and fixed with the connecting pin 31 and a limiting block 33 which is convexly arranged on the locking piece 8; the stopper piece 32 has a stopper groove portion 34 for allowing only the stopper 33 to slide circumferentially and an unlocking groove portion 35 for allowing both the stopper 33 to slide circumferentially and radially. In this embodiment, the connecting pin 31 is fixed by engaging the gear portion at the end thereof with the gear groove at the center of the stopper piece 32.
The specific working principle of the first limiting mechanism 9 is as follows:
as shown in fig. 6 to 9, when the enclosure frame 2 is located at the working position, the limiting block 33 is located in the limiting groove portion 34 of the limiting sheet 32, the first limiting mechanism 9 limits the locking member 8, and the locking member 8 cannot perform radial unlocking movement, so that the second locking mechanism 7 cannot be unlocked.
As shown in fig. 10 to 11, when the enclosure frame 2 is located at the unlockable position, the limit block 33 is located in the unlocking groove portion 35 of the limit sheet 32, the first limit mechanism 9 releases the limit on the locking member 8, and the locking member 8 can perform radial unlocking movement, thereby unlocking the second locking mechanism 7.
The first limiting mechanism 9 enables the second locking mechanism 7 to be unlocked only when the enclosure frame 2 is located at a specific unlocking position, so that the use is safer and more reliable, and accidental unlocking caused by misoperation in the use process is avoided.
As shown in fig. 2 to 4, a second limiting mechanism 36 is disposed between the seat pocket connector 3 and the lower surrounding frame 5. When the upper frame 4 and the lower frame 5 are in the unfolded state, the second limiting mechanism 36 enables the lower frame 5 to rotate only at the front part of the seat pocket connector 3. The design can avoid the situation that the user falls off due to excessive forward turning when the enclosure frame 2 is rotationally adjusted, and the use safety is greatly improved.
The second limiting mechanism 36 has the following specific structure: the second limiting mechanism 36 comprises a limiting block 37 which is arranged on the seat pocket connecting piece 3 and can move axially relative to the seat pocket connecting piece, a third spring 38 which is arranged between the limiting block 37 and the seat pocket connecting piece 3, a guide groove 39 which is arranged on the lower surrounding frame 5 and is used for the limiting block 37 to slide circumferentially, an installation groove 40 which is arranged on the lower surrounding frame 5 and is communicated with the guide groove 39, and a sliding block 41 which is arranged in the installation groove 40 and can move axially relative to the installation groove 40; the upper surrounding frame 4 has an active area for the sliding block 41 to move when the upper surrounding frame is folded and folded relative to the lower surrounding frame 5, and a boss 42 is arranged in the active area, and the boss 42 has an inclined surface matched with the sliding block 41.
The specific working principle of the second limiting mechanism 36 is as follows:
when the upper surrounding frame 4 and the lower surrounding frame 5 are in the unfolding state, the sliding block 41 is positioned in the moving area of the upper surrounding frame 4, the limiting block 37 is positioned in the guide groove 39, and when the surrounding frame 2 rotates, the limiting block 37 slides in the guide groove 39;
when the upper frame 4 and the lower frame 5 are folded, and when the boss 42 rotates to be matched with the inclined surface of the slide block 41, the slide block 41 moves axially and pushes the limiting block 37 out of the guide groove 39, and at this time, the lower frame 5 can rotate backwards relative to the seat pocket connecting piece 3 to the rear lower part, see fig. 12.
The use principle of the seat pocket provided by the invention is as follows:
as shown in fig. 1, 6, 8 and 9, when the seat bag is in a use state, the first locking mechanism 6 and the second locking mechanism 7 are both in a locking position, and the upper surrounding frame 4, the lower surrounding frame 5 and the seat bag connecting piece 3 are relatively fixed.
As shown in fig. 6, 8 and 9, when the seat pocket needs to be adjusted in the front-rear direction, the first locking mechanism 6 is unlocked, the second locking mechanism 7 is still in the locked state, and the surrounding frame 2 is in the unfolded state, and at this time, the surrounding frame 2 can rotate relative to the seat pocket connector 3 to change the angle between the two, so that the surrounding frame 2 can be switched between a plurality of working positions. The second locking mechanism 7 is restricted by the first limiting mechanism 9, so that unlocking cannot be carried out, and the use safety is ensured. Meanwhile, due to the limitation of the second limiting mechanism 36, the lower surrounding frame 5 can only rotate at the front part of the seat pocket connecting piece 3 and cannot rotate to the lower side and the rear lower part of the seat pocket connecting piece 3, and the use safety is further ensured.
As shown in fig. 10 and 12, when the seat bag needs to be folded, the first locking mechanism 6 is firstly unlocked, the second locking mechanism 7 is still in a locked state, the enclosure frame 2 is in an unfolded state, the enclosure frame 2 is turned forward to reach an unlockable position, at this time, the first limiting mechanism 9 releases the limitation on the locking piece 8, the second unlocking assembly 28 releases the locking of the second locking mechanism 7, the upper enclosure frame 4 is continuously turned forward, and the upper enclosure frame 4 and the lower enclosure frame 5 are folded and folded together and are turned downward. When the seat pocket connecting piece and the folding mechanism are folded to a certain angle, the second limiting mechanism 36 automatically releases the limitation on the lower surrounding frame 5, at the moment, the lower surrounding frame 5 can be opposite to the seat pocket connecting piece 3, the seat pocket connecting piece is further rotated backwards to the rear lower part of the seat pocket connecting piece, the folded and folded seat pocket can be better attached to a folded frame, the folding volume of the whole vehicle is further optimized, and therefore the whole vehicle can be conveniently stored and transported.
