Description

FIELD The present disclosure relates to electronic device peripherals, and in particular, to a display stand. BACKGROUND In both work and daily life, it is common to see that people using laptops select external displays to be connected to the laptops due to the inconvenience caused by a small screen size, which hampers operations. A control over the external displays is mainly achieved through the laptop's projection function, enabling the external displays to duplicate or extend the content shown on the laptop's built-in display, which provide laptop users additional display workspace. This method is widely applied in industries such as finance, design, and competitive gaming, where multi-window application processing or multi-screen synchronized presentations are frequently required. When assembling multiple external displays, stands are often necessary. However, the existing stands are typically fixed and do not allow for adjustments to an orientation or a position of the external displays. Moreover, the main body of these stands cannot be folded for storage, making it difficult to flexibly switch between usage modes in different scenarios and thus limiting their adaptability. D1 (US 12055971 B1) discloses a display bracket including a base and a first support component. The base is used for placing a laptop. The first support component is located on one side of the base, and the first support component is capable of rotating along a transverse length direction of the base. A back of the first support component is provided with a fixing device for installing an extended screen. The extended screen can be installed on the first support component through the fixing device on the first support component, and the laptop can be placed on the base. When the extended screen is installed on the first support component, an extension of a display of the laptop can be realized without a need to install the extended screen on the laptop display, so as not to damage the laptop and greatly improve user experience. D2 (EP 4339735) discloses a display device including a housing having a rectangular shape in plan view, a display having a screen surface exposed from a front face of the housing, and a stand disposed on a rear face of the housing and pivotable on a rotation axis at a center in a short-side direction of the housing, to open and close relative to the housing. The stand has a width in a long-side direction of the housing smaller than a width of the housing in the long-side direction. D3 (XP Number: 93336488, URL: https://www.youtube.com/watch?v=WN8xbFMr1X4) discloses a New Domyfan S6 Triple Screen Monitor, in which a stand having multiple configurations to accommodate two additional screens is shown. D4 (XP Number: 93336493, URL: https://www.voutube.com/watch?v=KODVSlcwpSs) discloses a Siaviala S6 Dual Display Portable Monitor - Laptop Screen Extender - Highly Adjustable, in which a stand having multiple configuration to accommodate two additional screens is shown. D5 (XP Number: 93336571, URL: https//web.archive.org/web/20241201090452/ https://www.amazon.com/domyfan-Extender-Portable-Monitor-Plug-Play/dp/BOD3VD32C9) discloses a laptop screen extender having a stand can support two additional screens. SUMMARY In order to solve shortcomings in existing technologies, the present disclosure is to provide a display stand, which not only can be unfolded to adjust an orientation or a position of an external display but also can be folded for storage. A display stand provided by the present disclosure includes a base plate and a support structure connected to the base plate and configured to be switched between an unfolded state where the support structure is configured to horizontally or vertically support the display stand on a placement surface and a folded state where the support structure is folded onto the base plate. When the support structure is in the unfolded state and is in a horizontally placed state, the support structure is configured to support a bottom of a device to be expanded and the base plate is configured to abut against a back of the device to be expanded; at least one expansion assembly is movably connected to the base plate and configured to mount at least one expansion screen. When the support structure is in the unfolded state and is in a vertically placed state, the support structure is configured to rotate a preset angle relative to the horizontally placed state to support the base plate and the at least one expansion assembly, and the base plate and the at least one expansion assembly are configured to mount and support the at least one expansion screen. Comparing with existing technologies, the display stand provided by the embodiments of the present disclosure has following beneficial effects: The support structure can be unfolded or folded relative to the base plate, enabling the display stand to be folded or unfolded. The support structure is designed to allow the display stand to b
