Display module

The invention relates to a display module, in particular to a display module capable of adjusting the lateral length and the longitudinal length of the support mechanism.

In recent years, portable computer devices have been widely used in daily life, such as Tablet Computer. Since the portable computer device can be conveniently carried by the user, the practical application has gradually replaced the desktop computer and has become the main platform for modern people to perform digital operations (such as word processing, Internet access, etc.).

In practical applications, in order to facilitate the user to place the portable computer device on the desktop for a long time, the common design is to pivot the support frame to the back side of the portable computer device to support the portable computer device. Upright or erected on the table. However, since the conventional support frame usually does not have the size adjustment function, the lateral length of the support frame tends to exceed the portable type when the portable computer device is switched from the erect state to the erect state. The upright width of the computer device causes the support frame to protrude from both sides of the portable computer device, thereby causing problems affecting the overall appearance of the portable computer device, or the longitudinal length of the support frame may be too small to enable the portable computer In the case where the center of gravity of the device is unstable, the problem that the portable computer device cannot stand upright on the carrying surface is caused, thereby causing a lot of inconvenience to the user in operating the portable computer device.

One of the objects of the present invention is to provide a display module that can adjust the lateral length and the longitudinal length of the support mechanism to solve the above problems.

According to an embodiment of the present invention, a display module of the present invention includes a display device and A support mechanism. The supporting mechanism is disposed on a back side of the display device to support the display device to stand upright or erect on a bearing surface, the supporting mechanism comprises an adjusting plate, a first sleeve structure, a second sleeve structure, a first and a second bending member, a third and fourth bending member, a third sleeve structure, and a fourth sleeve structure. The adjustment disk is disposed on the back side. The first sleeve structure is movably inserted into the adjustment disk to convert the display device to a position that is upright or erected. The second sleeve structure is disposed in parallel with the first sleeve structure. The first and second bending rod members are respectively telescopically disposed at two ends of the first sleeve structure. The third and fourth bending rod members are respectively telescopically disposed at two ends of the second sleeve structure. The third sleeve structure is respectively connected to one end of the first bending rod member away from the first sleeve structure and the third bending rod member is away from one end of the second sleeve structure to make the first bending At least one of the lever member and the third bent lever member is expandable and contractible relative to the third sleeve structure. The fourth sleeve structure is disposed opposite to the third sleeve structure and is respectively connected to the second bending rod member away from one end of the first sleeve structure and the fourth bending rod member is away from the second sleeve structure One end such that at least one of the second bending member and the fourth bending member are expandable and contractible relative to the fourth sleeve structure. The first and second bending members and the third and fourth bending portions when the first sleeve structure is switched from a position where the display device is erected to a position where the display device is erected The rods are respectively telescoped relative to the first sleeve structure and the second sleeve structure to adjust a lateral length of the support mechanism, and the first and third bending members and the second and fourth bending members The first sleeve structure and the fourth sleeve structure are respectively telescoped to adjust a longitudinal length of the support mechanism.

In summary, the present invention adopts a design in which a bent lever member can be extended and contracted with respect to a sleeve structure, so that the user can adjust the lateral length and the longitudinal length of the support mechanism, and thus the present invention provides The support mechanism can not only effectively solve the problem that the support frame mentioned in the prior art can protrude from both sides of the portable computer device when the portable computer device is erected, thereby affecting the overall appearance, and also preventing the support mechanism. The longitudinal length of the display device is too small to cause the display device to be unstable, so as to ensure that the display device can stably stand on the bearing surface, thereby greatly improving the operation convenience and the device aesthetics of the display module on the display device.
