[0030] like Figures 1 to 12In the embodiment of the intelligent car seat flipping device of this utility model shown, the intelligent car seat flipping device includes a folding box 1, a flipping box 2 rotatably connected to the folding box 1, a folding seat 3 installed on the flipping box 2, and flipping shafts (not shown in the figure) fixedly connected to both sides of the flipping box 2. The flipping shafts are rotatably connected to the folding box 1. The folding box 1 has cavities 5 on both sides of the flipping box 2. A first incomplete gear 6 is fixedly connected to the flipping shaft in the cavity 5. A push plate 7 that moves up and down is provided in the cavity 5. A vertical rack 8 is fixedly connected to the push plate 7. The vertical rack 8 meshes with the first incomplete gear 6.

[0031] Specifically, when the seat is folded, the push plate 7 moves downward, and the vertical rack 8 on the push plate 7 pushes the first incomplete gear 6 to rotate, causing the flip box 2 to rotate around the flip shaft. After rotating 90 degrees, the first incomplete gear 6 stops rotating due to the interruption of the gear teeth. When unfolded, the push plate 7 moves upward, driving the vertical rack 8 to drive the flip shaft to rotate until the flip box 2 is laid flat.

[0032] In one embodiment of this application, preferably, the folding seat 3 includes a backrest 31, a seat 32, and a folding armrest 33. The backrest 31 is rotatably connected to the seat 32, the seat 32 is slidably connected to the flip box 2, one end of the folding armrest 33 is rotatably connected to the seat 32, and the other end of the folding armrest 33 is rotatably connected to the backrest 31. The armrest 33 is used to extend to form an armrest when the backrest 31 and the seat 32 are extended, and the armrest 33 is folded and stored when folded, thus solving the problem of the armrest occupying a large space.

[0033] In one embodiment of this application, preferably, a sliding groove 9 is provided on the flip box 2, a gear seat 10 is slidably connected in the sliding groove 9, the gear seat 10 is fixedly connected to the seat plate 31, a horizontal rack 11 is fixedly connected to the bottom of the flip box 2 corresponding to the sliding groove 9, a first gear 12 is rotatably connected on the gear seat 10, the first gear 12 meshes with the horizontal rack 11, and is used to move the seat plate 32 forward after the flip box 2 is flipped.

[0034] In one embodiment of this application, preferably, a motor 13 is fixedly connected to the gear seat 10, and the drive shaft of the motor 13 is fixedly connected to the central shaft of the first gear 12. The motor 13 drives the first gear 12 to rotate, and the first gear 12 drives the gear seat 10 to move forward under the action of the horizontal rack 11, thereby driving the seat plate 32 to move forward.

[0035] In one embodiment of this application, preferably, a fixing plate 34 is provided at the connection between the seat plate 32 and the backrest 31. A rotating shaft 35 is rotatably connected to the fixing plate 34. A second incomplete gear 36 is fixedly connected to the rotating shaft 35. A second gear 37 is rotatably connected to the seat plate 32. A toothed groove 14 is provided on the flip box 2 to mesh with the second gear 37. The second gear 37 meshes with the second incomplete gear 36. When the seat plate 32 moves forward, the second gear 37 rotates under the action of the toothed groove 14. The second gear 37 drives the second incomplete gear 36 to rotate and drive the backrest 31 to unfold. During the unfolding process of the backrest 31, the folding armrest 33 is pulled to extend.

[0036] In one embodiment of this application, preferably, the folding box 1 is provided with a sealing component 15 at the bottom of the flip box 2, which is used to hide and cover the connection after the flip box 2 is flipped into the folding box 1, making it aesthetically pleasing and neat.

[0037] In one embodiment of this application, preferably, the sealing assembly 15 includes a sliding plate 151 and a telescopic plate 152. The sliding plate 151 slides up and down, and the top end of the sliding plate 151 abuts against the flipping box 2. The top end of the telescopic plate 152 and the bottom end of the sliding plate 151 are provided with wedge-shaped surfaces (not shown in the figure) that are adapted to each other. When the sliding plate 151 moves downward, it squeezes the telescopic plate 152 to retract. When the flipping box 2 flips downward, the flipping box 2 squeezes the sliding plate 151, causing the sliding plate 151 to move downward. The sliding plate 151 squeezes the telescopic plate 152, causing the telescopic plate 152 to move laterally inward.

[0038] In one embodiment of this application, preferably, the folding boxes 1 at both ends of the sliding plate 151 are provided with limiting grooves 153, and a slider 154 slides in the limiting grooves 153. The slider 154 is fixedly connected to the sliding plate 151. A vertical spring hole 155 is provided at the bottom of the limiting groove 153, and a vertical spring 156 is fixedly connected in the vertical spring hole 155. The other end of the vertical spring 156 is connected to the slider 154. A horizontal spring hole 157 is provided on the folding box 1 on one side of the telescopic plate 152. A guide post 158 ​​is slidably connected inside 157. The guide post 158 ​​is fixedly connected to the telescopic plate 152. A transverse spring 159 is also connected inside the transverse spring hole 157. One end of the transverse spring 159 abuts against the guide post 158. When the flip box 2 flips upward and folds into the folding box 1, the sliding plate 151 is reset under the action of the vertical spring 156. After the sliding plate 151 moves upward, the telescopic plate 152 is reset under the action of the transverse spring 159. After the reset is completed, it is flush with the folding box 1 and the flip box 2.

[0039] In one embodiment of this application, preferably, an electric push rod 16 is fixedly connected inside the cavity 5. The push rod of the electric push rod 16 is fixedly connected to the push plate 7 and is used to drive the push plate 7 to drive the vertical rack 8 to move up and down.

[0040] In summary, the intelligent car seat flipping device in the above embodiments of this utility model specifically involves the following steps: When the folded seat is extended, the electric push rod 16 retracts, driving the vertical rack 8 to move upward. The vertical rack 8 drives the first incomplete gear 6 to rotate, causing the flipping box 2 to flip outward. The flipping box 2 presses against the sliding plate 151. When the sliding plate 151 presses down against the telescopic plate 152, the telescopic plate 152 moves inward and presses against the transverse spring 159. The flipping box 2 stops when it reaches a horizontal position. The motor 13 is then activated, driving the first gear 12 to rotate. Under the action of the transverse rack 11, the first gear 12 drives the gear seat 10 to move forward, causing the seat plate 32 to move forward. The second gear 37 on the seat plate 32 rotates under the action of the tooth groove 14 on the flipping box 2 and drives the second incomplete gear 36 to rotate. The second incomplete gear 36 drives the seat back 31 to rotate. When the chair back 31 extends, the folding armrest 33 extends as well. When the chair back 31 rotates and extends to a certain angle, it stops, thus meeting the usage requirements. When folding, the motor 13 rotates in the reverse direction, causing the seat plate 32 to move backward. The toothed groove 14 causes the second gear 37 to rotate in the reverse direction, driving the chair back 31 to fold towards the seat plate 32. The folding armrest 33 folds along with the chair back 31. After the chair back 31 is folded, the electric push rod 16 pushes the vertical rack 8 downward, driving the flip box 2 to rotate into the folding box 1. The sliding plate 151 bounces upward and resets under the action of the vertical spring 156, and the telescopic plate 152 moves outward and resets under the action of the horizontal spring 159. By using the folding seat and the gear-driven flip box, the seat is folded and flipped into the folding box. By folding the seat, the folding space is compressed, which can meet the requirements of seat comfort and save folding space.
