[0048] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in

[0049] Specifically, a recessed groove 210 is formed in the backplane assembly 200. When the small table board assembly 100 is retracted, it can completely fall into the recessed groove 210 and will not protrude from the backplane assembly 200. The locking tongue member 500 is arranged on the side wall of the recessed groove 210 of the backplane assembly 200. When the table board assembly is retracted, the locking tongue 520 in the locking tongue member 500 on the backplane assembly 200 can be inserted into the unlocking member 400 on the small table board assembly 100, thereby completing the locking of the small table board assembly 100. When unlocking, the user can trigger the unlocking member 400 on the small table board assembly 100, so that the locking tongue 520 of the locking tongue member 500 disengages from the small table board assembly 100, thereby completing the unlocking of the small table board. Through such a setting, there is no need to arrange the unlocking member 400 on the backplane assembly 200, so that the space of the backplane assembly 200 can be vacated to install other functional components.

[0050] See Figure 1 - Figure 9 As shown, in an alternative solution of this embodiment, the small table board assembly 100 includes a table board bracket 110, a table board upper plate 120, and a table board lower plate 130; the table board upper plate 120 and the table board lower plate 130 are both arranged on the table board bracket 110, the unlocking member 400 is installed on the table board bracket 110, and an avoidance groove 131 for avoiding the unlocking member 400 is formed in the table board lower plate 130.

[0051] Among them, the unlocking member 400 includes an unlocking handle 410 and an unlocking base 420; the unlocking base 420 is fixed on the table board bracket 110, one end of the unlocking handle 410 is pivotally connected to the unlocking base 420, and an unlocking ejector rod 430 is arranged on the unlocking handle 410.

[0052] Among them, the locking tongue member 500 includes a locking tongue base 510, a locking tongue 520, and a locking tongue return spring 530; the locking tongue base 510 is arranged on the backplane assembly 200, the locking tongue 520 is inserted into the locking tongue base 510, the locking tongue return spring 530 is arranged between the locking tongue 520 and the locking tongue base 510, and the unlocking ejector rod 430 can abut against the locking tongue 520.

[0053] Among them, a locking tongue 520 slot is formed in the locking tongue base 510, a sliding groove 511 is formed in the side wall of the locking tongue base 510, the locking tongue 520 is inserted into the locking tongue 520 slot, an elastic card 521 is arranged on the outer wall of the locking tongue 520, and the elastic card 521 is slidably clamped in the sliding groove 511; one end of the return spring abuts against the bottom of the locking tongue 520 slot, and the other end abuts against the locking tongue 520.

[0054] Among them, a table board locking tongue groove 122 is arranged on the table board upper plate 120. Under the action of the locking tongue return spring 530, the locking tongue 520 can be inserted into the table board locking tongue groove 122, and the unlocking ejector rod 430 can eject the locking tongue 520 from the table board locking tongue groove 122.

[0055] The unlocking button 410 is installed on the unlocking base 420 through an unlocking pin, and a return torsion spring 411 is arranged between the unlocking button 410 and the unlocking base 420 .

[0056] See also Figure 1 - Figure 9 As shown, in an optional scheme of this embodiment, the connecting rod assembly 300 includes a long connecting rod 310 and a short connecting rod 320; one end of the long connecting rod 310 and the short connecting rod 320 are connected to the back panel assembly 200, and the other end is connected to the table board bracket 110, a table board return spring 311 is arranged between one end of the long connecting rod 310 and the back panel assembly 200, and a damper 312 is arranged between the other end of the long connecting rod 310 and the table board bracket 110; a connecting rod avoidance groove 121 is arranged on the upper plate 120 of the table board.

[0057] Wherein, a connecting rod groove decoration piece 140 is arranged on the connecting rod avoidance groove 121 .

[0058] Specifically, a transition arc surface is provided at one end of the lock tongue 520 close to the unlocking member 400. When the user lifts up the small table assembly 100 to lock the small table assembly 100, the lock tongue 520 slot on the small table assembly 100 can contact the transition arc surface of the lock tongue 520. Then, as the small table assembly 100 rotates, the lock tongue 520 slot can compress the lock tongue 520. The lock tongue 520 is compressed to compress the lock tongue return spring 530, thereby causing the lock tongue 520 to move into the lock tongue 520 slot. When one side of the lock tongue 520 slot passes over the lock tongue 520, the lock tongue 520 can be inserted into the lock tongue 520 slot under the action of the lock tongue return spring 530, and the locking of the small table assembly 100 is completed. When the small table assembly 100 needs to be unlocked, the user pulls the unlocking handle 410, and the unlocking handle 410 rotates relative to the unlocking base 420. When the unlocking handle 410 rotates, the reset torsion spring 411 is compressed (when the user releases the unlocking handle 410, the unlocking handle 410 can automatically reset). The rotation of the unlocking handle 410 can drive the unlocking push rod 430 to move, and the unlocking push rod 430 can move in the lock tongue 520 slot, thereby pushing the lock tongue 520 in the lock tongue 520 slot out (the lock tongue 520 can be compressed when it is away from the lock tongue 520 slot). The lock tongue reset spring 530 is retracted to allow the lock tongue 520 to reset), thereby completing the unlocking of the small table assembly 100, and when the small table assembly 100 is unlocked, the table reset spring 311 between the long connecting rod 310 and the back panel assembly 200 will drive the long connecting rod 310 to rotate, and the rotation of the long connecting rod 310 can drive the small table assembly 100 to unfold, and at the same time, the damper 312 between the long connecting rod 310 and the table bracket 110 can slow down the swinging speed of the long connecting rod 310, so that the small table assembly 100 can be smoothly unfolded.

[0059] This embodiment provides a car seat, including a table top structure with an unlocking structure.
