[0026] The present invention is further described below in conjunction with embodiments and drawings.

[0027] like Figure 1 and Figure 3 As shown, a car seat small table with a built-in driving mechanism includes a small table body 1, and the small table body 1 is connected to a transmission component 3, and the transmission component 3 is used to make the small table body 1 flippably assembled on the back side of the seat back. The small table body 1 is integrated with a driving mechanism 2, and the driving mechanism 2 is used to drive the transmission component 3 to move so that the small table body 1 can flip and switch between an unfolded position and a folded position.

[0028] like Figure 4 As shown, the driving mechanism 2 includes a slider 23 and a synchronization rod 25, wherein the synchronization rod 25 is a square shaft, which is rotatably mounted in the small table body 1 along the length direction of the small table body 1, and a sleeve 27 is fixedly sleeved in the middle of the synchronization rod 25, and a rocker arm 242 is provided on the sleeve 27 along its radial direction, and a connecting rod 241 is hinged at the end of the rocker arm 242, and the other end of the connecting rod 241 is rotatably connected to the slider 23. The small table body 1 has a hollow installation chamber 11 inside, and two groups of slide grooves 111 are provided inside the hollow installation chamber 11 parallel to the length direction of the screw rod, and the ends of the slider 23 can be reciprocated and mounted in the slide grooves 111. The small table body 1, the slider 23, the connecting rod 241 and the rocker arm 242 constitute a four-bar linkage. In order to balance the force on the slider 23, there are two groups of rocker arms 242 and connecting rods 241, which are symmetrically arranged on both sides of the slider 23. A torsion spring 26 is sleeved on the synchronization rod 25, and two ends of the torsion spring 26 are supported on the rocker arm 242 and the small table body 1 respectively, which can make the driving mechanism run more stably and without shaking.

[0029] like Figure 4 As shown, the driving mechanism 2 also includes a power assembly for driving the slider 23 to reciprocate. In this embodiment, the power assembly includes a motor 21 fixed in the small table body 1 and a screw rod 22 driven by the motor 21. The screw rod 22 is arranged in the middle of the synchronization rod 25 along the width direction of the small table body 1. The slider 23 is threadedly sleeved with the screw rod 22 and moves along the length direction of the screw rod 22. Driven by the screw rod 22, it can not only be tightly installed inside the small table body 1, but also be able to follow the horizontal movement, hover at any position, and meet greater load-bearing and abuse forces.

[0030] like Figure 1 and Figure 4 As shown, the synchronization rod 25 is connected to the transmission assembly 3, and the transmission assembly 3 includes a mounting member 33, and a first transmission rod 31 and a second transmission rod 32 rotatably connected to both ends of the mounting member 33, as shown in FIG. Figure 2 As shown, the mounting member 33 is used for fixed installation on the back side of the seat back, and the first transmission rod 31 and the second transmission rod 32 are both in two groups, and are symmetrically arranged on both sides of the width direction of the small table body 1. The end of the first transmission rod 31 away from the mounting member 33 is rotatably connected to the small table body 1, and the end of the second transmission rod 32 away from the mounting member 33 is fixedly connected to the synchronization rod 25. The first transmission rod 31, the second transmission rod 32, the small table body 1 and the mounting member 33 form a four-bar linkage mechanism. Both sides of the small table body 1 are provided with a receiving groove 12, and the first transmission rod 31 and the second transmission rod 32 pass through the receiving groove 12. When the small table body 1 is in the folded position, the first transmission rod 31 and the second transmission rod 32 are located in the receiving groove 12.

[0031] like Figure 2 As shown, when the small table body 1 is in the folded position, it is close to the seat back to avoid compressing the rear seat space. Figure 3 and Figure 4 As shown, when the small table body 1 is in the unfolded position, the motor 21 first drives the screw rod 22 to rotate, and the slider 23 is threadedly matched with the screw rod 22. Since the two ends are restricted by the slide groove 111, the slider 23 reciprocates along the length direction of the screw rod 22. The two ends of the slider 23 are connected to the connecting rod 241 and the rocker arm 242, forming a power transmission to the synchronization rod 25, driving the synchronization rod 25 to rotate, and the small table body 1 is unfolded relative to the seat back under the transmission action of the two groups of first connecting rods 31 and second transmission rods 32 connected at the two ends of the synchronization rod 25. The small table body 1 can be adjusted at a large angle through a small and compact structural design, and the drive mechanism 2 can be integrated inside the small table body 1 with a small volume without increasing the thickness of the small table body 1.

[0032] like Figure 3As shown, in this embodiment, the driving mechanism 2 is arranged inside the small table body 1 along the horizontal direction of the small table body 1, and the thickness of the small table body 1 can be controlled within 45 mm. The small table body 1 is connected to the back side of the seat back through the transmission component 3, does not occupy the internal space of the backrest, does not affect the arrangement of the internal modules of the seat backrest, and ensures the comfort of riding.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
