[0058] See also Figure 1 - Figure 8 As shown, in an optional solution of this embodiment, the cup holder assembly 300 includes a slide box 310, a rotating shaft 320 and a cup holder 330; the guide slide includes a first guide slide 211 and a second guide slide 212, the slide block includes a first slide block and a second slide block, the slide box 310 is provided with a first slide block, and the first slide block is slidably arranged in the first guide slide 211; one end of the rotating shaft 320 is connected to the cup holder 330, and the other end is rotatably inserted in the slide box 310.

[0059] Specifically, a first guide slot 211 and a second guide slot 212 are provided on the armrest frame 200 . The first guide slot 211 is used for the sliding of the slide box 310 , and the second guide slot 212 is used for the sliding of the sliding auxiliary seat plate 350 .

[0060] Among them, a first slide slot block is arranged on the slide box 310, and the first slide slot block can be stuck in the first guide slide slot 211 without falling off, and the first slide slot block can slide freely in the first guide slide slot 211; the second slide slot block can be stuck in the second guide slide slot 212 and slide freely like the first slide slot block.

[0061] It should be pointed out that one end of the rotating shaft 320 is connected to the cup holder 330, and the other end is rotatably inserted in the slide box 310. The rotating assembly 500 is disposed in the slide box 310, and is rotatably connected to the rotating shaft 320 to drive the rotating shaft 320 to rotate. The rotation of the rotating shaft 320 can drive the cup holder 330 to rotate, thereby realizing that the cup holder 330 can freely switch between the vertical state and the horizontal state.

[0062] See also Figure 1 - Figure 8 As shown, in the optional scheme of this embodiment, the rotating assembly 500 includes a reset torsion spring 510, an end seat 520, a toggle seat 530, a toggle rod 540, a transmission seat 550 and a guide pin 560; the end seat 520 is fixed on the rotating shaft 320, the reset torsion spring 510 is sleeved on the rotating shaft 320, one end of the reset torsion spring 510 is connected to the slide box 310, and the other end is connected to the end seat 520; the slide box 310 is provided with a slot 311, and the guide pin 560 is connected to the transmission seat 550, The guide pin 560 is inserted into the slot hole 311, the toggle seat 530 is fixed on the rotating shaft 320, one end of the toggle rod 540 is pivotally connected to the toggle seat 530, and the other end is pivotally connected to the transmission seat 550; a rotating slide groove 201 adapted to the guide pin 560 is opened on the armrest frame 200, and the end of the rotating slide groove 201 close to the cup holder 330 has a downward guiding groove 202, so that the guide pin 560 drives the transmission seat 550 to slide in the slot hole 311 to drive the rotating shaft 320 to rotate.

[0063] Specifically, when the slide box 310 slides out of the armrest shell 100, the guide pin 560 provided on the transmission seat 550 slides synchronously with the slide box 310, and the guide pin 560 slides in the rotating slide groove 201. When the cup holder 330 extends out of the armrest shell 100 as a whole, the guide pin 560 moves into the guide groove 202 of the rotating slide groove 201, and when the cup holder 330 continues to extend outward, the guide pin 560 moves downward under the guidance of the guide groove 202. At this time, the guide pin 560 can drive the transmission seat 550 to move downward, and the transmission seat 550 drives the toggle seat 530 to rotate through the toggle rod 540, thereby driving the cup holder 330 to rotate. When the cup holder 330 extends outward to the maximum, the guide pin 560 can rotate the toggle rod 540 by 90 degrees, thereby rotating the folded cup holder 330 from a vertical state to a horizontal state for use by the user.

[0067] In addition, the shaft seat 220 is fixed relative to the armrest frame 200 , and one end of the driving member 400 is disposed on the shaft seat 220 , so that when the cup holder 330 is extended, the driving member 400 using a spring roll can drive the slide box 310 to approach the shaft seat 220 .

[0068] The driving member 400 is a spring roll, one end of which is connected to the slide box 310 , and the other end is connected to the shaft seat 220 , so that the spring roll drives the slide box 310 to reciprocate along the first guide slot 211 .

[0069] See also Figure 1 - Figure 8As shown, in an optional solution of this embodiment, the cup holder assembly 300 further includes a fixed rod 340, a sliding auxiliary seat plate 350 and a damping gear 360; one end of the fixed rod 340 is fixedly arranged on the slide box 310, and the other end is fixedly connected to the sliding auxiliary seat plate 350, and the fixed rod 340 is parallel to the rotating shaft 320; a second slide groove block is arranged on the sliding auxiliary seat plate 350, and the second slide groove block is slidably arranged in the second guide slide groove 212; the damping gear 360 is arranged on the sliding auxiliary seat plate 350, and a rack 230 is arranged on the armrest frame 200, and the damping gear 360 is meshed with the rack 230.

[0070] Specifically, a fixing rod 340 is provided on the sliding auxiliary seat plate 350 , and one end of the fixing rod 340 away from the sliding auxiliary seat plate 350 is fixedly connected to the slide box 310 , so the sliding auxiliary seat plate 350 can move synchronously with the movement of the slide box 310 .

[0071] Among them, a damping gear 360 is arranged on the sliding auxiliary seat plate 350, and a rack 230 is arranged on the armrest frame 200. Through the cooperation of the damping gear 360 and the rack 230, the moving speed of the sliding auxiliary seat plate 350 can be reduced, thereby reducing the moving speed of the sliding seat box 310, improving the smoothness of the movement of the cup holder 330, avoiding the cup holder 330 from popping out too fast, and reducing the collision between internal parts.

[0072] In addition, a locking rod 351 is provided on the sliding auxiliary seat plate 350 , and a locking member 240 is provided on the armrest frame 200 . The opening and closing of the telescopic cup holder 330 can be controlled by the cooperation between the locking member 240 and the locking rod 351 .
