[0025] The shielding plate 4 is located below the armrest assembly 2, and the track 62 extends from one end close to the armrest base 1 to one end away from the armrest base 1. When the first convex shaft 61 is arranged on the armrest assembly, the track 62 is arranged on the shielding plate 4. When the first convex shaft 61 is arranged on the shielding plate 4, the track 62 is arranged on the armrest assembly 2, and the first convex shaft 61 is inserted into the track 62 and is slidably connected to the track 62.

[0026] The shielding plate 4 is provided with a clamping claw, and the armrest base 1 is provided with a second convex shaft 11 , and the clamping claw is rotatably connected to the second convex shaft 11 .

[0027] Specifically, the armrest assembly 2 is rotatably connected to the rotating shaft 12 on the armrest base 1 through the armrest rotating shaft pin 3.

[0028] In this embodiment, by providing the armrest pivot pin 3, the armrest assembly 2 is rotatably connected to the armrest base 1 by using the armrest pivot pin 3, so that the armrest assembly 2 can rotate relative to the armrest base 1. By providing the shielding plate 4 below the armrest assembly 2, the shielding plate 4 is connected to the armrest base 1, such as Figure 2 and Figure 4As shown, in embodiment 1, a track 62 is provided on the shielding plate 4, and the first protruding shaft 61 on the handrail assembly 2 is inserted into the track 62, so that the shielding plate 4 can be stably connected to the handrail assembly 2, so that the shielding plate 4 can be used to shield the handrail rotating shaft pin 3 to prevent the handrail rotating shaft pin 3 and other structures in the handrail assembly 2 from being damaged; Figure 5 and Figure 6 As shown, in Embodiment 2, a track 62 is provided on the armrest assembly 2 , and the first protruding shaft on the shielding plate 4 is inserted into the track 62 .

[0029] At the same time, by setting the track 62 to extend from one end close to the armrest base 1 to the end away from the armrest base 1, the first cam 61 is slidably connected to the track 62, and by setting a claw on the shielding plate 4 and setting a second cam 11 on the armrest base 1, and using the claw to rotate and connect to the second cam 11, when the armrest assembly 2 rotates relative to the armrest base 1, the shielding plate 4 rotates around the second cam 11, and the first cam 61 can slide along the track 62, thereby driving the shielding plate 4 and the armrest assembly 2 to rotate synchronously, so that the armrest assembly 2 always blocks the armrest pivot pin 3, further preventing the armrest pivot pin 3 and other structures in the armrest assembly 2 from being damaged.

[0030] Optionally, one end of the track 62 close to the armrest base 1 is open, and one end of the track 62 away from the armrest base 1 is closed.

[0031] In this embodiment, the track 62 is specifically configured as a U-shaped structure placed transversely. By opening the end of the track close to the armrest base 1, the first protruding shaft 61 can be easily inserted into the track 62, and by closing the end of the track 62 away from the armrest base 1, the closed end of the track can be used to limit the first protruding shaft 61 to prevent the first protruding shaft 61 from leaving the track.

[0032] Alternatively, if Figure 2 As shown, the flip armrest shaft shielding mechanism also includes a shielding plate torsion spring 41, which is assembled and connected to the shielding plate 4 and connected to the armrest base 1, and the axial direction of the shielding plate torsion spring 41 is parallel to the axial direction of the second convex shaft 11.

[0033] In this embodiment, specifically, a connecting column is provided on the shielding plate 4, and the shielding plate torsion spring 41 is sleeved on the connecting column. By assembling and connecting the shielding plate torsion spring 41 with the shielding plate 4, and connecting the shielding plate torsion spring 41 with the armrest base 1, and the axial direction of the shielding plate torsion spring 41 is parallel to the axial direction of the second convex shaft 11, when the shielding plate 4 rotates around the second convex shaft 11, the shielding plate torsion spring 41 can be driven to compress. Similarly, when the shielding plate torsion spring 41 is extended, it can drive the shielding plate 4 to rotate in the opposite direction around the second convex shaft 11, and simultaneously drive the armrest assembly 2 to rotate in the opposite direction so that the armrest assembly 2 automatically returns to its original position.

[0034] Alternatively, if Figure 2 As shown, the flip armrest shaft shielding mechanism also includes an armrest box 5, and the armrest box 5 is connected to the armrest base 1 by bolts, and the armrest box 5 and the armrest base 1 are both located below the armrest assembly 2.

[0035] In this embodiment, by providing the armrest box 5, small items such as beverages and water cups can be stored in the armrest box 5, so that the driver can easily get these small items when needed. At the same time, the armrest box 5 is provided below the armrest assembly 2, and the armrest assembly 2 can be turned over to cover the armrest box 5 to cover the upper end opening of the armrest box 5, so as to prevent dust from entering the armrest box 5, and facilitate the driver to use the armrest assembly 2 to place his arms for rest.

[0036] At the same time, by connecting the armrest box 5 and the armrest base 1 with bolts, the armrest base 1 and the armrest box 5 can be easily assembled and connected, and the armrest box 5 and the armrest base 1 are both located below the armrest assembly 2, which makes it convenient to use the flippable armrest assembly 2 to cover the armrest box 5.

[0037] Alternatively, if Figure 1 and Figure 2 As shown, the flip armrest shaft shielding mechanism also includes a box baffle 51. The armrest box 5 is opened on one side close to the armrest base 1. The box baffle 51 is arranged at the opening and connected to the armrest base 1 through a clip.

At the same time, by providing a box baffle 51, and the box baffle 51 is provided at the opening of the armrest box 5, the box baffle 51 can be used to cover the opening of one side of the armrest box 5. In addition, by connecting the box baffle 51 with the armrest base 1 through a clip, the box baffle 51 can be easily assembled.
