Embodiment
[0032] A cam balancer for automotive displays such as figure 1 As shown, the cam balancer is arranged at the upper end of the entire vehicle display near the top position. Its whole is arranged near the rotating shaft 2 . The rotating shaft 2 is a hollow shaft, which is internally used to carry the signal and power lines of the display. The vehicle display can rotate around the rotating shaft 2, and the rotating shaft 2 is fixedly connected to the vehicle body and remains relatively stationary. One end of the rotating shaft 2 runs through the display support 1, and the other end is rotatably mounted on a rotating block 23, which is fixedly installed on the display, and the rotating shaft 2 is connected in rotation with the rotating block 23, and the form of the rotating connection is connected through a bearing or an axle sleeve. Such as figure 2 and image 3 , A fixed block 3, a laterally moving block 4, a cam 5, and an elastic member 6 are sequentially inserted on the r...

The invention discloses a cam balancer for a vehicle display, and aims at overcoming the defects that most of a mechanism of an existing vehicle display is arranged at the end away from a rotation shaft, the gravity center of the whole mechanism deflects to the middle position of the display, in the vehicle display usage process, display swinging can be possibly caused due to slight acceleration changes of a vehicle, and the display can be supported through a bigger elastic mechanism. The cam balancer comprises a rotation shaft, a fixing block, a transverse moving block, a cam and an elastic piece, the transverse moving block is provided with a contact end, and the contact end is attached to the curve outline on the cam. The cam and the contact end are matched so that the overturning movement of the display can be converted into the transverse moving movement of the transverse moving block on the rotation shaft. The whole device is integrated to the position near the rotation shaft, the gravity center of the whole display is closer to the upper position, the sensitive degree of the display to the vehicle acceleration becomes small through the gravity center closer to the upper position, the requirement for elastic force of the elastic piece is lowered, and larger-size displays can be supported.
Description
technical field [0001] The invention relates to the technical field of automobile information display terminals, more specifically, it relates to a cam balancer used for automobile displays. Background technique [0002] Existing vehicle-mounted flat-panel displays are usually installed on the ceiling in the vehicle. In order to reduce the space in the vehicle, a liquid crystal screen (hereinafter referred to as the display panel) is installed on the flipping device. This overturning device has a mounting bracket fixed on the roof of the car, and a display bracket installed on the back of the display panel. When not in use, the display bracket is turned up and stored so that the display surface of the display panel is close to the ceiling of the car. . When in use, the display support of the turning device is turned down, so that the display board is erected. The closed state of the vehicle display is that the display is attached to the ceiling of the vehicle. When in use...
