[0038] In the embodiment, please refer to Figure 3 The T-shaped sliding block 331 is fixed to one side of the fixed block 33.

[0039] The T-shaped sliding groove 23 is arranged on one side of the adjusting cavity, and the groove body of the T-shaped sliding groove 23 is in sliding connection with the T-shaped sliding block 331.

[0040] It should be noted that in the embodiment, the T-shaped sliding groove 23 and the T-shaped sliding block 331 are matched to improve the stability of the fixed block 33, so that the fixed block 33 is prevented from rotating with the bidirectional screw rod 32.

[0041] In the embodiment, please refer to Figure 3 The limiting plates 351 are fixed to the plurality of top corners on the inner side of the neck support body 35, and the limiting plates 351 are in sliding connection with the cavity of the adjusting cavity.

[0042] It should be noted that in the embodiment, the limiting plates 351 facilitate limiting the position of the neck support body 35, and the stability of the neck support body 35 is enhanced.

[0043] The specific operation mode of the utility model is as follows:

[0044] The adjustable automobile rear-row intermediate seat is characterized in that the first motor 31 drives the bidirectional screw rod 32 to rotate, thereby driving the two fixed blocks 33 to move in opposite directions, further driving the arm rod 34 to rotate, and the rotation of the arm rod 34 drives the neck support body 35 to move, thereby controlling the protruding degree of the neck support body 35.

[0045] The second motor 51 drives the worm 52 to rotate, thereby driving the worm gear 53 to rotate, and thus the angle adjustment of the intermediate seat 20 is realized.
