A first embodiment of the present invention is a seat pocket angle adjusting apparatus.
Fig. 1 is a schematic view of a seat pocket angle adjusting apparatus according to a first embodiment of the present invention. As shown in fig. 1, a seat pocket angle adjusting device mounted on a seat includes: the seat pocket driving rod 12 is fixed on a fixing surface of the seat pocket 8; the seat pocket driving rod 12 moves on the fixed base sliding groove 11, and the fixed base 1 is positioned below the fixed base sliding groove 11 and is integrated with the fixed base sliding groove 11; the seat pocket driving device comprises a connecting rod 13 and a screw nut 2, wherein one end of the connecting rod 13 is connected with the screw nut 2, the other end of the connecting rod 13 is connected with a seat pocket driving rod 12, and the screw nut 2 drives the connecting rod 13 so as to drive the seat pocket driving rod 12 to move on a fixed base sliding groove 11; the screw rod 3 and the driving motor 7, one end of the screw rod 3 is connected to the fixed base 1 through a screw rod fixing part 14, the other end of the screw rod 3 is connected with the driving motor 7, and the driving motor 7 is fixed on the fixed base 1 through a motor fixing seat 6; the auxiliary driving rod 15 and the auxiliary driving rod 15 are also fixed on the fixing surface of the seat pocket driving rod 12 and the seat pocket 8 and are driven by the seat pocket driving rod 12 to move. In the mode shown in fig. 1, the seat pocket driving lever 12 moves upward, thereby moving the seat pocket 8 upward together. Fig. 5 shows another schematic view of the seat pocket angle adjusting means. As shown in fig. 5, the auxiliary driving lever 15 is moved by the seat pocket driving lever 12, and when the seat pocket driving lever 12 moves from the start position to the end position, the auxiliary driving lever 15 also moves from the start position to the end position. Through this kind of structure, driving motor 7 rotates and will drive screw-nut 2 and realize linear motion, and rethread connecting rod 13 has just realized the pitch arc motion of seat pocket actuating lever 12 on unable adjustment base spout 11, owing to possessed and driven the auxiliary drive pole 15 that moves by seat pocket actuating lever 12 in addition, carries out assistance-localization real-time through auxiliary drive pole 15, lets the regulation more stable, and the structure is more stable.
Preferably, but not necessarily, the length, curvature, and position of the slide groove 11 of the stationary base define an adjustable angle range of the seat pocket 8, and position detection sensors (a start position detection sensor 9 and an end position detection sensor 10) are set at both start and end positions of the slide groove 11 of the stationary base for detecting an extreme position state, thereby preventing the stalling phenomenon of the driving motor 7.
Preferably, but not necessarily, a current position detection sensor 4 and a grating disk 5 are further fixed on the shaft of the lead screw 3, and the current position detection sensor 4 is matched with the grating disk 5 and feeds back all the intermediate position states.
Therefore, the seat pocket angle adjusting device adopts an electric adjusting mode, the angle adjustment belongs to stepless adjustment, and the adjusting speed can be controlled, so that the adjustment is stable, the mode is not easy to wake up children in sleep, and meanwhile, the motor is adopted to drive the screw rod and screw mechanism to achieve a self-locking mechanism, so that the safety seat provided with the seat pocket is safer in collision.
Fig. 2 is a schematic view of a local control switch wired to the seat pocket angle adjusting means of fig. 1.
