[0030] In this embodiment, the touch screen 3 can be completely installed inside the connection frame 1 or partially installed inside the connection frame 1, and partially extend out of the connection frame 1. When the touch screen 3 is in the initial state, the four sides of the touch screen 3 are in contact with the inner wall of the connection frame 1, so that there is no gap between the touch screen 3 and the connection frame 1, and dust is prevented from entering the connection frame 1. When the touch screen 3 is pressed inward and then released, the fixed connection component 2 drives the sliding and rotating connection component 4 to slide outward, so that the touch screen 3 is out of the connection frame 1. The touch screen 3 can be freely rotated and the tilt angle can be adjusted as needed. The touch screen 3 can be adjusted to a horizontal screen state or a vertical screen state to increase the user's operating experience. The connection frame 1 can be set to a square shape, and the touch screen 3 cannot rotate in the connection frame 1. In other embodiments, the connection frame 1 can be set to a circular shape, and the touch screen 3 can rotate in the connection frame 1. When the touch screen 3 is pressed inward and then released, the touch screen 3 can rotate outside the connection frame 1.

[0031] In this embodiment, the four sides of the touch screen 3 are fitted with the inner wall of the connecting frame 1 so that there is no gap between the touch screen 3 and the connecting frame 1, thereby preventing dust from entering the connecting frame 1. By setting the fixed connection component 2 in the connecting frame 1 and the sliding and rotating connection component 4 on the touch screen 3, when the touch screen 3 is pressed inward, the fixed connection component 2 can drive the sliding and rotating connection component 4 to slide outward, so that the touch screen 3 can be detached from the connecting frame 1, and then the angle of the touch screen 3 can be freely adjusted outside the connecting frame 1 through the sliding and rotating connection component 4, thereby solving the technical problem in the related art that the touch screen in the vehicle-mounted multimedia device cannot have both the function of freely adjusting the angle and avoiding the accumulation of dust in the gap between it and the center console.

[0033] In this embodiment, the sliding ring 41 can move along the axial direction of the fixed connection component 2, and the ball shaft 42 is rotatably connected to the ball shaft sleeve 43, so that the ball shaft 42 can rotate with the touch screen 3 to control the free rotation of the touch screen 3 and adjust the tilt angle.

[0034] Further, see Figure 1 and Figure 2As shown, in some embodiments, a connecting groove 411 is provided on one side of the sliding ring 41 close to the ball sleeve 43, and a splicing ring 431 is provided on one side of the ball sleeve 43 close to the sliding ring 41. The splicing ring 431 is inserted into the connecting groove 411 so that the ball shaft 42 is plugged into the sliding ring 41.

[0037] In this embodiment, the sliding ring 41 is limited to different positions of the fixed connection component 2 by the locking mechanism. When the touch screen 3 is in the initial state, the locking mechanism is located at the first locking position 21, and the touch screen 3 is located in the connection frame 1. When the touch screen 3 is pressed inward, the fixed connection component 2 drives the sliding and rotating connection component 4 to slide outward, so that the locking mechanism moves to the second locking position 22, so that the overall length of the fixed connection component 2 and the sliding and rotating connection component 4 becomes longer, and the touch screen 3 escapes from the connection frame 1.

[0041] In this embodiment, when the touch screen 3 is in the initial state, the pin block 413 is located at the first locking position 21, and the touch screen 3 is located in the connecting frame 1. When the touch screen 3 is pressed inward, the touch screen 3 pushes the sliding ring 41 to slide inward along the axis of the fixed shaft 23, so that the locking mechanism disengages from the first locking position 21, and the pin block 413 slides under the action of the limit drive assembly 25 until it moves to the second locking position 22, the overall length of the fixed connection assembly 2 and the sliding and rotating connection assembly 4 becomes longer, and the touch screen 3 disengages from the connecting frame 1.

[0042] Further, see Figure 1-4As shown, in some embodiments, the limit drive assembly 25 includes a sliding conical stop block 251, and the sliding conical stop block 251 is sleeved on the fixed shaft 23. The cross-sectional areas of the sliding conical stop block 251 and the fixed conical stop block 24 gradually decrease from the side close to each other to the side away from each other.

When the touch screen 3 is pressed inward and then released, the touch screen 3 pushes the sliding ring 41 to slide inward along the axis of the fixed shaft 23, and the pin block 413 retracts to the position where it is located under the extrusion force of the sliding conical stopper 251. In the through hole, the pin block 413 slides through the sliding conical stopper 251 under the action of thrust, and stops at the second limit block 252, and then slides in the opposite direction through the sliding conical stopper 251 and the fixed conical stopper 24 that fit each other under the elastic force of the tension spring 253 until it moves to the second locking position 22, and the fixed connection component 2 drives the sliding and rotating connection component 4 to slide outward, the overall length of the fixed connection component 2 and the sliding and rotating connection component 4 becomes longer, and the touch screen 3 escapes from the connection frame 1.
