Description

Rotation device for display panel

technical field

The invention relates to a rotating device of a display panel, in particular to a device capable of deflecting the display panel left and right.

Background technique

With the advancement of technology, the display system has been widely installed on the central control panel (Dashboard) between the driver's seat and the front seat passenger, so that the driver or passengers can grasp the first-hand driving information through the information displayed on the system .

Please refer to Figure 1. The current display system for vehicles is roughly divided into a main unit M, a display panel group P, and a box body C according to its composition structure. In the box body C, the display panel group P includes a sliding base P1 and a display P2, wherein the sliding base P1 has a rotary drive group P3 and a drive group (not shown), and the display P2 is a pivot It is connected to the front end of the sliding base P1 and is controlled by the rotating group P3 at the same time. Therefore, when the sliding base P1 is driven by the driving group (not shown in the figure), and the display P2 is loaded out of the box C , and then rotate the display P2 from a horizontal state to a vertical state by the rotating drive group P3, so that the driver or passengers can read the information displayed on the display P2.

However, the above-mentioned existing structure hinders the general LCD display panel from viewing the line of sight as much as possible to be 90° to the panel, and the quality of the image viewed by it is the best. The central control panel between the front seat and the front seat passenger cannot be adjusted according to the viewing direction of the viewer, resulting in poor image quality. Therefore, a device that can rotate and deflect the display panel to the left and right has been developed. , its typical device such as: U.S. Patent US6731350 "Display Panel Mounted on Vehicles (VEHICLE MOUNTED DISPLAY SYSTEM)", this patent mainly uses the drive group known to drive the sliding base (movable base) to load the display panel out of the box It is divided into the first driving group and the second driving group, and is respectively engaged with the first and second racks provided on the chassis, so that the sliding base can move relative to the chassis, thus, when the first and second When the driving groups are driven synchronously, they drive the sliding base to carry the display panel out of the box, and then the rotating driving group raises the display panel from a horizontal state to a vertical state. When the first driving group and the second driving group are When driving in opposite directions, the sliding base is rotated to one side and shifted, so as to achieve the purpose of biasing the display panel to one side.

However, since the first drive group and the second drive group in the aforementioned patent case move linearly along the first and second racks on the chassis, in order to make the display panel deflect left and right smoothly, the aforementioned patent case uses the first The first driving group and the second driving group are pivotally connected to the sliding base, and when the display panel rotates, the first driving group and the second driving group can swing in accordance with their offset directions, so that the display panel can face to one side Therefore, in order to keep the first and second driving groups continuously engaged with the rack when swinging, it is necessary to set a tension spring (Spring) between the two driving groups and the sliding base, so that When the first driving group and the second driving group swing according to the shifting direction of the display panel, the driving groups can be kept in meshing state with the matched rack by virtue of the elastic force of the spring.

However, this kind of use of the elastic force of the spring to control the meshing state of the driving group and the rack not only increases the number of components, but also easily causes the driving group to fail to engage on the rack due to the elastic fatigue of the spring during long-term use. Therefore, In terms of durability and production cost, it is not an ideal structural design.
