When the backrest latch gear linkage 12 and the backrest latch structure part B36 rotate clockwise, the backrest body 2 tilts backward. At this time, the backrest latch structure part B36 cannot rotate to its extreme position and will not lift the table 22. At this time, the backrest latch transmission rod 13, the backrest latch fixing part 34, and the backrest latch structure part A35 at the backrest body 2 remain stationary.

[0063] Example 6

[0064] like Figures 1 to 15 As shown, an automatic folding car seat includes all the contents of Embodiment 5. Furthermore, the 90° folding process of the backrest body 2 is as follows:

[0065] Seat cushion latch assembly movement: When seat cushion latch structure part B33 rotates to its extreme position, it continues to rotate, which will drive the three structures of seat cushion latch fixing part 31, seat cushion latch structure part A32, and seat cushion latch gear connecting rod 14 to move together. When the protruding part of seat cushion latch structure part B33 locks the groove part of seat cushion latch structure part A32 and rotates, seat cushion latch structure part A32 will move left and right under the influence of the thread structure of seat cushion latch gear connecting rod 14. Seat cushion latch fixing part 31 cannot move left and right because it needs to fix the first rotating arm 11, it can only rotate.

[0066] Backrest latch assembly movement: When the backrest latch structure part B36 rotates to its extreme position, it continues to rotate, which in turn drives the backrest latch fixing part 34, the backrest latch structure part A35, and the backrest latch transmission rod 13 to move together. When the protruding part of the backrest latch structure part B36 engages with the groove part of the backrest latch structure part A35 and rotates, the backrest latch structure part A35 will move left and right under the influence of the threaded structure of the backrest latch transmission rod 13. The backrest latch fixing part 34 cannot move left and right because it needs to fix the transmission spur gear 21, so it can only rotate.

[0067] Example 7

[0068] like Figures 1 to 15As shown, an automatic folding car seat includes the entire content of embodiment 5, in addition, the lifting process of the table plate 22 is: the back plate body 2 moves to the obliquely downward rear under the action of the first rotating arm 11, the second rotating arm 20 and the gas spring support structure 9, and then the table plate 22 is lifted; when the backrest tenon gear connecting rod 12 and the backrest tenon structure part B 36 rotate counterclockwise to the lower extreme point, continue to rotate, the backrest tenon structure part B 36 will drive the backrest tenon structure part A 35 and the backrest tenon fixing part 34, through the transmission straight gear 21 carried on the backrest tenon fixing part 34 and the upper transmission chain 10 transmission to the transmission bevel gear 7, and all the way to the spring transmission rod 30 above, lift the table plate 22; the support mode is: the rotating spring rod 6 is rotated and popped out through the spring transmission rod 30; then the rotating support rod 4 moves and rotates with the slide 8, and supports the table plate 22; when the spring rod 6 reaches the head, it supports together with the support rod of the rotating support rod 4; at this time, the left motor transmission rod 18 of the cushion tenon assembly, the cushion tenon structure part B 33, the cushion tenon structure part A 32, the cushion tenon fixing part 31, the cushion tenon gear connecting rod 14 drive the second rotating arm 20 and the gas spring support structure 9 connected thereto to move, pull the backrest of the seat as a whole to the rear; to give the user foot space, it can also shorten the distance between the rear seat user and the table plate 22; the first rotating arm 11 and the gas spring support structure 9 connected thereto will be linked with the second rotating arm 20 to pull the back plate body 2 backward.

[0069] The present application designs a brand new tenon structure, which is composed of four parts. In the present application, there are two sets of this structure. It can flexibly cope with the sitting posture adjustment process and the transformation process from the seat to the table. The goal of the present application is to facilitate flexible control of the space in the car without the need for hand, waist and back coordination control. After gesture recognition, it can be quickly triggered. The structure is low-carbon, efficient and easy to maintain, and can realize the transformation of the seat. After transformation, it is a small table that occupies a small space and can be flexibly used, which is convenient for car sharing, intelligent auxiliary driving and other application scenarios. The linkage transformation transmission structure and the seat shape are innovated. In order to reduce the complexity of the structure, the entire structure realizes the backrest angle adjustment and folding transformation with one motor.

[0070] Supplementary explanation of the tenon structure:

[0071] In order to avoid the conflict between parts during transmission, the tenon structure part is designed in the backrest and seat part.

[0072] 1. When adjusting the sitting posture backrest angle:

[0073] The upper backrest tenon assembly:

[0074] When leaning forward, the T-shaped tenon of the backrest tenon structure part B 36 rotates counterclockwise slightly;

[0075] When reclining backward, the T-shaped tenon of the backrest tenon structure part B36 rotates clockwise slightly;

[0076] The lower cushion tenon assembly:

[0077] When reclining forward, the T-shaped tenon of the cushion tenon structure part B33 rotates clockwise slightly;

[0078] When reclining backward, the T-shaped tenon of the cushion tenon structure part B33 rotates counterclockwise slightly.

[0079] 2. In folding step (I):

[0080] Power affects the T-shaped tenon of the upper backrest tenon structure part B36 to rotate counterclockwise to the extreme point position through the transmission rod of the backrest tenon gear connecting rod 12.

[0081] Power affects the T-shaped tenon of the lower cushion tenon structure part B33 to rotate clockwise to the extreme point position through the transmission rod of the left motor transmission rod 18.

[0082] 3. In folding step (II), the two sets of tenons move simultaneously:

[0083] When pulling the backrest to the obliquely downward rear, the upper backrest tenon structure part B36 rotates to the extreme point, and then rotates, and the T-shaped tenon of the backrest tenon structure part B36 rotates counterclockwise, driving the backrest tenon structure part A35 to move.

[0084] When the table board is raised, the upper backrest tenon structure part B36 rotates to the extreme point, and then rotates, and the T-shaped tenon of the backrest tenon structure part B36 rotates counterclockwise, driving the backrest tenon structure part A35 to move.
