[0047] like Figure 1-Figure 8 As shown, a seat backrest with a cup holder 2 and a table top 3 in this embodiment mainly includes: a backrest body 1, a cup holder 2, a table top 3, a cup base 4, a connecting rod 5 and a locking mechanism 6.

[0048] like Figure 1-Figure 5 As shown, the cup holder 2 is movably arranged on the back side of the backrest body 1, and the cup holder 2 has a first folded position and a first unfolded position on the back side of the backrest body 1, and the cup holder 2 can move between the first folded position and the first unfolded position. When the cup holder 2 is in the first folded position, it is folded in the receiving groove 10 of the backrest body 1, and is in close contact or approximately in close contact with the back side of the backrest body 1. When the cup holder 2 is rotated upward by 90 degrees from the first folded position, it moves to the first unfolded position, at which time, a cup can be placed on the cup holder 2. Specifically, the water cup holder 2 of the present embodiment has a water cup through hole, and a plurality of movable clamping blocks 22 are arranged around the water cup through hole. The plurality of movable clamping blocks 22 can telescope in the water cup through hole to engage with water cups of different diameters. In order to realize the telescopic movement of the movable clamping block 22, a spring is arranged on the back side of the movable clamping block 22. The spring tensions the movable clamping block 22. When a water cup with a large diameter is placed in the water cup through hole, the water cup pushes against the spring to retract the movable clamping block 22, and the movable clamping block 22 engages with the water cup to ensure the stability of the water cup placement.

[0049] The table top 3 is movably arranged on the back side of the backrest body 1, and the table top 3 has a second folded position and a second unfolded position on the back side of the backrest body 1, and the table top 3 can move between the second folded position and the second unfolded position. When the table top 3 is in the second folded position, it is folded in the receiving groove 10 on the back side of the backrest body 1, and when it is rotated downward by about 90 degrees, it moves to the second unfolded position.

[0050] During actual use, when the cup holder 2 is in the first folded position and the table top 3 is in the second folded position, the table top 3 covers the cup holder 2; when the cup holder 2 is in the first unfolded position and the table top 3 is in the second unfolded position, the cup holder 2 and the table top 3 both extend from the back side of the backrest body 1.

[0051] In this embodiment, the cup holder 2 and the table board 3 are both foldable and arranged on the back side of the backrest body 1, and when the cup holder 2 and the table board 3 are folded, the cup holder 2 is on the inner side of the table board 3, and the table board 3 shields the cup holder 2, ensuring the aesthetics of the car seat, and effectively solving the problem of spatial arrangement of the large-capacity cup holder 2, and will not affect the thickness of the table board 3. In addition, there is no need to set a cup groove or other structure on the table board 3 to ensure that the use area of ​​the table board 3 is not affected. When facing impact, luggage and other experiments, the cup holder 2 is protected by the table board 3 and is not easy to cause harm to the occupants.

[0052] A cup holder 4 is movably disposed on the back side of the backrest body 1. The cup holder 4 has a third folded position and a third unfolded position, and the cup holder 4 can move between the third folded position and the third unfolded position. When the cup holder 4 is in the third folded position and the table top 3 is in the second folded position, the table top 3 shields the cup holder 4. During use, after the cup passes through the cup holder 2, the bottom can be supported by the cup holder 4 to ensure the stability of the cup when placed.

[0053] Among them, Figure 3-Figure 6 As shown, a mounting bracket 11 is arranged on the back side of the backrest body 1, and the mounting bracket 11 can be integrally arranged with the backrest or separately arranged, preferably separately arranged. A baffle 12 is arranged on the mounting bracket 11, and the baffle 12 can block the locking mechanism 6. The water cup holder 2 and the water cup base 4 can be rotatably mounted on the mounting bracket 11. One end of the connecting rod 5 is rotatably connected to the water cup base 4, and the other end of the connecting rod 5 is rotatably connected to the water cup holder 2. A four-link mechanism is formed between the mounting bracket 11, the water cup holder 2, the connecting rod 5 and the water cup base 4, so that the water cup holder 2 and the water cup base 4 can be synchronously unfolded and synchronously folded.

[0054] The cup base 4 is connected to the cup holder 2 by a connecting rod 5, and the cup base 4 and the cup holder 2 can be synchronously unfolded and folded. Specifically, two first bosses are extended from the inner side and the outer side of the cup base 4, and the two first bosses on the inner side are rotatably connected to one end of the two connecting rods 5, and the two first bosses on the outer side are rotatably connected to the mounting bracket 11, and the two first bosses on the inner side are offset from the center of the two first bosses on the outer side. Two second bosses are extended from the inner side and the outer side of the cup holder 2, and the two second bosses on the inner side are rotatably connected to the other end of the two connecting rods 5, and the two second bosses on the outer side are rotatably connected to the mounting bracket 11, and the two second bosses on the inner side are offset from the center of the two second bosses on the outer side. Therefore, the mounting bracket 11, the cup holder 2, the connecting rod 5 and the cup base 4 can form a four-link 5 mechanism, and the linkage of the cup holder 2 and the cup base 4 is realized through the connection of the connecting rod 5. During use, when the cup base 4 and the cup support 2 are synchronously unfolded, the cup base 4 rotates downward by ninety degrees, and the cup support 2 rotates upward by ninety degrees.

[0055] Among them, a power torsion spring 20 is provided between the mounting bracket 11 and the water cup bracket 2, or between the mounting bracket 11 and the water cup bottom bracket 4. The elastic force of the power torsion spring 20 makes the water cup bracket 2 have a tendency to move to the first unfolded position, and / or makes the water cup bottom bracket 4 have a tendency to move to the third unfolded position. That is, whether the power torsion spring 20 is provided between the mounting bracket 11 and the water cup or between the mounting bracket 11 and the water cup bottom bracket 4, the water cup bracket 2 and the water cup bottom bracket 4 can be unfolded after unlocking, and the elastic force of the power torsion spring 20 provides a driving force for the unfolding of the two.

[0056] Preferably, if Figure 4 Combined with Figure 7-Figure 8As shown, a locking mechanism 6 is arranged on the back side of the backrest body 1. When the cup holder 2 is in the first folded position, the locking mechanism 6 can lock the cup holder 2. The locking mechanism 6 includes an unlocking button 60 and two locking members 61. The two locking members 61 are rotatably and symmetrically mounted on the mounting bracket 11. Specifically, a boss is protruded on the mounting bracket 11, and the locking members 61 are rotatably mounted on the boss to form a lever structure. A buckle 21 is arranged on the cup holder 2. When the cup holder 2 is in the first folded position, one end of the two locking members 61 is engaged with the buckle 21 to lock the cup holder 2. A driving block 62 is arranged at the bottom of the unlocking button 60. The other end of the two locking members 61 is movably against the driving block 62. Pressing the unlocking button 60 can drive the two locking members 61 to disengage from the buckle 21 to unlock the cup holder 2. A first spring 63 is provided at the bottom of the driving block 62, and the elastic force of the first spring 63 pushes against the driving block 62. After unlocking, the first spring 63 can drive the driving block 62 and the unlocking button 60 to reset. A second spring 64 is provided at one end of the two locking members 61 away from the buckle 21, and the elastic force of the two second springs 64 makes the two locking members 61 have a tendency to move in the locking direction.

[0057] During actual use, the cup holder 2, the cup base 4 and the table top 3 are all folded on the back side of the backrest body 1 in a natural state. When a cup needs to be placed, the table top 3 is first rotated from the second folded position to the second unfolded position, that is, the table top 3 is unfolded. Press the unlock button 60, and the unlock button 60 drives the drive block 62 to move downward (that is, the inclined surfaces on both sides of the drive block 62 also move downward). Under the elastic force of the second spring 64 on both sides of the two locking members 61, the locking ends of the two locking members 61 move away from each other, and the two locking members 61 are disengaged from the buckle 21 of the cup holder 2, realizing one-key unlocking. After unlocking, under the action of the power torsion spring 20, the cup base 4 and the cup holder 2 are unfolded synchronously, that is, one-key unfolding is realized, and the user can place the cup on the cup holder 2 and the cup base 4.

[0058] This solution effectively solves the problem that there is no space for a large-capacity cup holder 2 on the backrest of the front-row car seat with a table 3. In the folded state, the overall thickness of the cup holder 2 does not exceed 30 mm, which requires little space and does not affect the overall thickness of the seat or the thickness of the table 3. The cup holder 2 is hidden on the backrest body 1 covered by the table 3, which does not affect the overall appearance of the car seat. In addition, when facing impact, luggage and other tests, the cup holder 2 is protected by the table 3 and is not likely to cause harm to the occupants. At the same time, the integrity, consistency and area utilization of the table 3A surface are guaranteed, and there is no need to provide a cup groove.
