Description

TECHNICAL FIELD

[0001] The utility model relates to the field of vehicle-mounted electronic equipment, in particular to a screen slide and turnover motion device. BACKGROUND

[0002] With the development of automobile industry technology, more and more automobile media functions have emerged, people's requirements for automobile ride comfort, technology, audio and video entertainment are higher and higher, and good ride environment is the guarantee for the stable driving of the driver and passenger. More and more functions of the automobile result in less space available for the driver and passenger, and the reduction of physical buttons, in addition, the driver and passenger have the need to control and display the functions of each module of the vehicle, so the vehicle-mounted turnover display screen is produced.

[0003] At present, the display screen turnover device on most automobiles is driven to turn over through a physical shaft, so that the screen needs to be translated for a distance before starting the turnover motion to avoid interference with other structures. This setting method needs to reserve a certain space inside the mounting seat for the installation and translation process of the physical shaft, so it will cause the overall volume of the device to be larger, which brings a greater burden to the already compact in-vehicle space. In addition, the rotating shaft is fixed during the turnover process, which results in low flexibility and variability of the device design, making it difficult to make corresponding adjustments according to different use environments and use requirements. In addition, the screen shakes greatly during the rotation of the physical shaft, and also shakes easily after the screen turnover is completed, so the stability is poor, which seriously affects the use experience of the passenger.

The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. Embodiment 1

[0044] Please refer to Figures 1 to 10 A screen sliding and flipping device, comprising a mounting seat 1, a screen support 2, a driving assembly 3 and a backlash elimination assembly 4.

[0045] Specifically, the first sliding groove 11 and the second sliding groove 12 in the embodiment are both arc-shaped.

[0046] The screen support 2 is used for mounting the display screen 21. In use, the driving motor 31 drives the screen support 2 to rotate through the transmission gear set and the arc-shaped teeth 22 on the screen support 2. When the screen support 2 rotates, the rotating gear 23 moves along the first sliding groove 11 through the meshing part 133, and the sliding block 24 slides along the second sliding groove 12. The upper and lower ends of the screen support 2 form respective support structures and movement tracks through the first sliding groove 11 and the second sliding groove 12, so that the operation process is more stable, and the entity shaft and the area reserved for the translation of the display screen 21 are not needed, thereby effectively reducing the overall volume of the device and saving space. In addition, the meshing part 133 in the shape of a rack is matched with the rotating gear 23, so that the fitting gap can be reduced, and the stability of the screen support 2 during operation can be improved.

[0047] In the formula, the reference Figure 8 When the screen support 2 rotates, the elastic sheet 41 slides in the arc-shaped groove 421.

In addition, after the screen support 2 stops rotating, the static frictional force between the elastic sheet 41 and the arc-shaped groove 421 when they are at rest can support the weight of the screen support 2 and the display screen 21, always provide holding force for the screen support 2, so that the display screen 21 can be suspended at any angle and will not be out of position and shake, and the use stability and reliability are improved.

[0048] Preferably, the driving motor 31 is a stepping motor, so as to accurately control the rotation angle of the display screen 21.

[0050] It should be noted that in some other embodiments, by adjusting the shapes of the first sliding groove 11 and the second sliding groove 12, the movement track of the screen support 2 can be changed, so that the device can be flexibly applied to different use environments and use requirements, and the flexibility and practicability of use are improved. Figure 1 and Figure 3 The screen support 2 further comprises a connecting shaft 25, and the rotating gears 23 are sleeved on both ends of the connecting shaft 25. By arranging the connecting shaft 25, the coaxial rotation of the rotating gears 23 on both sides is ensured, and the rotating gears 23 are also convenient to position and install during assembly.

[0051] It should be noted that in some other embodiments, by adjusting the shapes of the first sliding groove 11 and the second sliding groove 12, the movement track of the screen support 2 can be changed, so that the device can be flexibly applied to different use environments and use requirements, and the flexibility and practicability of use are improved.
