Description

Technical Field

[0001] The utility model relates to the technical field of electronic display devices, in particular to a display. Background Art

[0002] When people use portable monitors to view displayed content (such as watching film and television materials), they often need to tilt the monitor, which requires the use of a stand to keep the monitor in a tilted state. However, existing monitors do not have their own stands. Therefore, the monitor needs to be equipped with an additional protective case with a stand. The presence of the protective case will undoubtedly weaken the heat dissipation capacity of the monitor, resulting in poor battery life and display stability of the monitor. Moreover, the purchase of the protective case also increases the user's cost of use. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a display with a self-supporting structure.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a display, comprising a body, a support plate and a rotating shaft assembly, wherein the rotating shaft assembly comprises a first structural member, a second structural member, a limiting bolt and an elastic member, the limiting bolt comprises a matching limiting screw and a nut, the head of the limiting screw is non-circular, the first structural member has a countersunk hole adapted to the head of the limiting screw, and the second structural member has an arc-shaped through-groove for the tail of the limiting screw to pass through; the elastic member is sleeved on the limiting screw, and the elastic member respectively contacts the nut and the second structural member. The elastic member is retractable along the axial direction of the limiting screw; the first structural member is provided with an arc-shaped guide block, and the second structural member is provided with an arc-shaped guide groove that cooperates with the arc-shaped guide block, and the arc-shaped guide groove is connected to the arc-shaped through-groove; the first structural member is provided with a plurality of positioning pits, and the second structural member is provided with a positioning protrusion that cooperates with the positioning pits, when the first structural member and the second structural member are rotated to different angles relative to each other, the positioning protrusions cooperate with different positioning pits; the first structural member is connected to the main body, and the second structural member is connected to the top of the support plate.

[0005] In one embodiment, the elastic members in the rotating shaft assembly are in a plurality of groups, and each group includes two symmetrically arranged conical spring washers.

[0006] In one embodiment, the elastic member is a spring.

[0007] In one embodiment, the rotating shaft assembly further includes a friction washer disposed between the elastic member and the second structural member.

[0008] In one embodiment, a plurality of positioning pits are provided on at least one side of the arc-shaped guide block, and the plurality of positioning pits located on the same side of the arc-shaped guide block are arranged in an arc.

[0009] In one embodiment, a plurality of positioning recesses are provided on both sides of the arc-shaped guide block.

[0010] In one embodiment, the main body is provided with a receiving groove for receiving the support plate.

[0011] In one embodiment, a bottom surface of the receiving groove is provided with an accommodating groove for accommodating the second structural member.

[0012] In one embodiment, the receiving groove is connected to the peripheral wall of the body.

[0013] In one embodiment, a magnetic member is provided on the support plate, and the support plate in the folded state is magnetically attached to the main body through the magnetic member.

[0014] The beneficial effects of the present invention are:

[0015] The monitor comes with a support plate that can tilt the display surface of the monitor, eliminating the need for users to purchase an additional protective case with a bracket, which helps reduce user costs.

[0016] With the cooperation of the positioning pits and the positioning protrusions, the relative angle between the support plate and the display body can be maintained, so that the display can stably maintain the tilt angle, ensuring that the support plate will not rotate unexpectedly relative to the body, which is conducive to enhancing the user experience;

[0017] When the user rotates the support plate, the positioning protrusion in a positioning pit disengages from the positioning pit, and the second structural member moves along the axial direction of the limit screw, and the elastic member is compressed until the positioning protrusion falls into another adjacent positioning pit. The elastic member is reset, and the tilt degree of the display can be adjusted. The user adjustment operation process is very simple. Compared with the shaft structure with an elastic plunger, the shaft assembly in this display has low processing accuracy requirements and low assembly difficulty. BRIEF DESCRIPTION OF THE DRAWINGS
