Self-reset rotating shaft system of display equipment

Abstract

Directed at the large volume and high cost of current display device, the invention provides an automatic reset shaft system, comprising: a fixing pedestal, a central shaft, a rotary support, a cam assembly and a pressure accumulating device; the central shaft is fixed to the fixing pedestal on one side, the rotary support is arranged to rotate around the central shaft and used for arranging the display device, one end of the cam assembly is fixed to the rotary support to set the stop angle of the rotary support, one end of the pressure accumulating device is connected with the cam assembly to accumulate pressure energy and apply the axial pressure of the central shaft to the cam assembly, the released pressure of the pressure accumulating device can drive the cam assembly to spur the rotary support to automatic reset from a specific angle to the stop angle. The invention has the advantages that: the volume is decreased, the cost is lowered, the maintenance requirements of electronic gadgets are reduced, and the operation is easy.

Description

technical field [0001] The invention relates to a rotating shaft system for automatic reset of a display device, in particular to a rotating shaft system related to automatic reset of a vehicle display screen. Background technique [0002] In recent years, with the advancement of information, the use of car monitors has become more and more popular. Nowadays, the monitors in the car not only have the function of entertainment and playback, but also can cooperate with the traffic road information system, global satellite positioning system, vehicle internal parts status query warning and The real-time monitoring system of the surrounding images of the vehicle, etc., provide the driver with more information on road driving and vehicle safety control, and become an indispensable part of the future intelligent vehicle driving system. [0003] However, when the car display is used in the car, its arrangement must consider the limitation of the interior space of the car, the viewi...

Problems solved by technology

In Fig. 1, the roof display device p1 is a display screen, and its opening and closing is directly operated manually by the user. When the display screen is closed, a fixed switch device p4 (such as a hook or a latch) is used to cooperate with the base p2 To fix the display device, the disadvantage is that it must be manually operated by the user. At the same time, because the fixed switch device must cooperate with a larger base, it also increases the overall volume of the device.

Please refer to Fig. 2, which is a schematic diagram of another traditional car roof display device. In Fig. 2, the car roof display device p7 is opened and closed through a motor drive. Since the motor drive device p8 must be added, it not only requires a larger base Space is used for placement, but also increases the overall cost
