Description

Technical Field

[0001] This utility model relates to the structure of an intelligent laser projector. Background Technology

[0002] A smart projector, as the name suggests, is a miniature projector with a built-in operating system. The functions differ depending on the operating system. In the market, smart projectors are mainly divided into two categories: Android smart projectors and Linux-based smart projectors. They are a type of smart electronic product that has emerged in recent years. These projectors feature expandable hardware and software, human-computer interaction, and multimedia connectivity, enabling applications such as web search, online video, video-on-demand (VOD), digital music, online educational resources, and more.

[0003] Smart projectors are becoming the third information access terminal after computers and mobile phones, allowing users to access the information they need anytime. Smart projectors are also becoming a type of intelligent device. By enabling cross-platform searching between projectors, networks, and applications, smart projectors are also becoming "entertainment centers," allowing users to search for various online resources, conduct long-distance meetings, and even transmit satellite and online videos.

[0004] In terms of application scenarios, the smart projector market has experienced rapid growth in the past two years, leading to an increasing number of participants seeking to expand their market share beyond the living room. From a spatial perspective, with the continuous growth of nighttime consumption, outdoor scenarios will rapidly expand; features such as children's modes and karaoke modes will also be quickly implemented. Therefore, more and more cross-industry brands are entering the smart projector market, intensifying competition.

[0005] Currently, the smart projector industry faces challenges such as upstream companies controlling core product technologies, manufacturers having low bargaining power, high R&D costs, severe product homogenization, poor product experience, and rapidly evolving user demands. This necessitates manufacturers improving their R&D capabilities, continuously developing smart home technologies, constantly innovating, deeply understanding user habits, and enhancing the consumer experience, rather than seeking quick gains that could erode consumer confidence. Furthermore, proactively upgrading smart home technologies is crucial for small home appliances to break through the current competitive landscape. Utility Model Content

A rear interface plate 24 is installed on the notch at the rear side of the plastic middle frame. The upper part of the rear interface plate has several connectors for connecting to a circuit board or power board.

[0038] In this embodiment, an upper cover 100 is installed at the upper end of the enclosure frame. The upper cover is fixed to the middle frame assembly by a snap-fit ​​mechanism. The plastic middle frame is provided with a snap-fit ​​groove 25, and the snap-fit ​​of the upper cover is provided with a C-angle to facilitate the release of the upper cover. The middle frame assembly and the rear interface plate are installed on the lower cover assembly by a snap-fit ​​structure and locked to the optical engine bracket by screws. The rear interface plate is also locked to the middle frame assembly by bolts.

[0039] In this embodiment, a power button 140 connected to a circuit board or power board is installed on the upper cover. The power button includes a power button and a button plate, which are respectively locked into the upper cover with screws to form an upper cover assembly. The structure of this physical switch button includes a keycap and silicone, and the silicone triggers the button to operate.

[0041] Specifically, the aforementioned camera module and ranging module are fixed to the front side of the plastic frame via camera bracket 111, with the camera module and ranging module extending through a metal mesh. The camera module and ranging module are equipped with a dustproof structure using silicone sleeves.

[0042] Specifically, the aforementioned lens bracket assembly includes a lens bracket 131, which is locked and installed inside the mounting hole at the front of the mid-frame assembly. An aluminum decorative ring 132 is fixed inside the lens bracket with adhesive backing. A first dustproof foam 133 is provided between the lens bracket and the optical engine module. A decorative ring 134 is installed inside the mounting hole at the front of the mid-frame assembly via a snap-fit ​​structure.
