[0025] This embodiment relates to a bracket with an expansion function, such as Figure 1 and Figure 2As shown in the figure, the bracket includes a base plate 1 and a bottom plate 4 hinged to the bottom of the base plate 1. The bottom plate 4 can be unfolded or stored relative to the base plate 1.

The base plate 1 has a front side and a back side, and the front side can support the back of the device to be expanded. Among them, the device to be expanded can be a device such as a tablet computer, a notebook computer, a mobile phone or a handheld game console. Specifically, the device to be expanded in this embodiment is a notebook computer.

[0026] Preferably, a plurality of expansion interfaces 43 are provided on the bottom plate 4. The expansion interfaces 43 are all coupled to the control circuit board inside the bottom plate 4. A part of the expansion interfaces 43 can be coupled to the device to be expanded and / or the expansion screen, and another part of the expansion interfaces 43 can be coupled to external electronic devices, so that the device to be expanded and / or the expansion screen can indirectly couple external electronic devices through the expansion interfaces 43, thereby realizing the function expansion of the device to be expanded and / or the expansion screen, making the bottom plate 4 have a function similar to that of a docking station. Specifically, the external electronic device can be a fan, a mobile hard disk or a mobile power supply, etc.

[0027] In other embodiments, a rechargeable battery coupled to the control circuit board can be built into the bottom case, and the expansion screen and the device to be expanded can be directly charged through the expansion interface 43. The rechargeable battery can also be connected to an external power supply through the expansion interface 43 to supply power to the rechargeable battery.

[0028] Preferably, a secondary plate 2 is movably assembled on the base plate 1. The number of secondary plates 2 is not limited, and can be one, two or three, etc. In this embodiment, there are two secondary plates 2. The secondary plate 2 can slide horizontally or vertically relative to the base plate 1. Specifically, the secondary plate 2 can slide horizontally relative to the base plate 1. An assembly plate 3 is rotatably connected to one side of the secondary plate 2, and the assembly plate 3 can be used for assembling the expansion screen. Since the sliding distances of the two secondary plates 2 can be controlled separately, two expansion screens of different sizes can be adapted for splicing and assembly.

[0029] Preferably, a second rotating shaft 41 is provided between the base plate 1 and the bottom plate 4. The expansion interface 43 is provided on the bottom plate 4 on the side close to the second rotating shaft 41. A hole with a shape adapted to the bottom plate 4 is opened on the base plate 1. When the bottom plate 4 rotates into the hole, the storage of the bottom plate 4 can be completed. The second rotating shaft 41 is provided on the side of the hole away from the secondary plate 2. A butting block 42 is provided on the bottom plate 4 on the side close to the second rotating shaft 41. The butting block 42 can limit the rotation amplitude of the bottom plate 4, so that the bottom plate 4 is flush with the hole after being stored.

[0030] It should be added that the longitudinal section of the bottom plate 4 is wedge-shaped, and the surface of the bottom plate 4 for placing the bottom of the device to be expanded after expansion is inclined, so as to place the device to be expanded, especially the keyboard part of the notebook computer, obliquely, improving the typing efficiency and comfort. Anti-slip patterns can also be provided on the surface of the bottom plate 4 for placing the bottom plate 4 of the device to be expanded, and the anti-slip patterns can prevent the notebook computer from slipping off the bracket.

[0031] Preferably, at least two sliding grooves 11 are provided on one side of the substrate 1 close to the assembly plate 3, and at least one slider 21 is provided on each of the two auxiliary plates 2.

In this embodiment, four sliding grooves 11 are provided, and two sliders 21 are provided on each auxiliary plate 2.

[0032] It should be added that the auxiliary plate 2 is assembled on the back of the substrate 1, and the assembly plate 3 is hinged to the side of the auxiliary plate 2 away from the substrate 1. At this time, the assembly plate 3 and the auxiliary plate 2 form a hinge structure. When the hinge structure is closed, the assembly plate 3 is in a storage state; when the hinge structure is opened, the assembly plate 3 is in an unfolded state. An adsorption part 32 is provided on the side of the assembly plate 3 away from the auxiliary plate 2, and the adsorption part 32 is used to adsorb the expansion screen. Specifically, the adsorption part 32 is used to adsorb the back of the expansion screen, so as to fixedly assemble the expansion screen on the bracket. Whether the assembly plate 3 and the auxiliary plate 2 are in a storage state or an unfolded state, the assembly plate 3 can adsorb the expansion screen, so that the bracket has multiple usage states.

[0033] In the first usage state, that is, as shown in the appendix Figure 2 As shown, the assembly plate 3 and the auxiliary plate 2 are in an unfolded state. In this embodiment, the expansion angle of the assembly plate 3 in the unfolded state relative to the auxiliary plate 2 is 180°. The orientation of the expansion screen on the adsorption part 32 is the same as or similar to the orientation of the front of the substrate 1. At this time, the two expansion screens are respectively located on the left and right sides of the substrate 1. Subsequently, the device to be expanded is placed on the bottom plate 4 and abutted against the substrate 1, and the usage requirement that the two expansion screens are respectively located on the left and right sides of the device to be expanded can be realized. In other usage scenarios, the assembly plate 3 rotates relative to the auxiliary plate 2 to other angles, such as rotating to 90°. At this time, the orientation of the expansion screen on the adsorption part 32 is perpendicular to the orientation of the substrate 1, and the usage effect similar to that of a multi-sided screen can be realized.

[0034] In other embodiments, the maximum expansion angle of the assembly plate 3 relative to the auxiliary plate 2 is 190°, 200° or 210°, etc. In this embodiment, the assembly plate 3 can enable the expansion screen and the device to be expanded to achieve a usage effect similar to that of a curved screen.

[0035] In the second usage state, that is, as shown in the appendix Figure 3As shown in the figure, when the assembly plate 3 and the secondary plate 2 are in the closed state, the orientation of the extended screen on the adsorption part 32 is the same as or similar to the orientation of the back surface of the substrate 1. At this time, the bracket can realize the left - right splicing of the two extended screens. The device to be extended can be placed on the bottom plate 4 or can be placed separately from this bracket.

[0036] Preferably, in the second usage state, a support frame 5 can also be set at the bottom of the substrate 1. The support frame 5 is set in a "U" shape. The top of the substrate 1 is a rectangular plate, and the bottom of the substrate 1 is set in a "∏" shape. After the support frame 5 is unfolded, it forms an angle with the substrate 1. The unfolded support frame 5 can cooperate with the bottom of the substrate 1, so that the entire display screen bracket can be horizontally supported on the placement surface. Specifically, the unfolded support frame 5 can form two - foot support with the substrate 1 on the placement surface. At this time, the substrate 1 is inclined, and the degree of inclination of the substrate 1 changes according to the unfolding angle of the support frame 5.

[0037] In the third usage state, that is, as shown in the attached Figure 4 figure, the bracket is placed laterally relative to the above - mentioned two usage scenarios. At this time, the assembly plate 3 is in the storage state, but the secondary plate 2 is in the unfolded state. The secondary plate 2 and the unfolded support frame 5 form two - foot support on the placement surface. The two extended screens on the assembly plate 3 are spliced up and down, so as to realize the usage mode of the upper - lower combined screen.

[0038] It should be added that a side plate 6 can also be set on the side of the support frame 5. The rotation center line of the side plate 6 is perpendicular to the rotation center line of the support frame 5. The unfolded side plate 6 can cooperate with the unfolded secondary plate 2 to support the bracket longitudinally on the placement surface; the inclination amplitude of the entire bracket relative to the placement surface can also be adjusted by adjusting the rotation angle of the side plate 6 relative to the support frame 5. Specifically, when using the side plate 6, the support frame 5 needs to be unfolded first, then the secondary plate 2 is unfolded. There is no need to unfold the assembly plate 3, and then the side plate 6 is unfolded. The side plate 6 and the secondary plate 2 can form two - foot support on the placement surface.

[0039] As Figure 5 shown in the figure, the assembly plate 3 includes a plate body 33. The adsorption part 32 is a magnet 322. An installation groove 321 for embedding the magnet 322 is opened on the side of the plate body 33 away from the secondary plate 2. A cover body covering the installation groove 321 is also set on the plate body 33, so as to assemble the magnet 322 inside the assembly plate 3.

[0040] It should be added that the secondary plate 2 and the support plate are rotationally assembled through a first rotating shaft 31, the support frame 5 and the substrate 1 are rotationally assembled through a third rotating shaft 51, and the side plate 6 is rotationally assembled with the support frame 5 through a fourth rotating shaft 61.
