Problems solved by technology

[0002] With the increasing market of projectors and colorful customer groups, there are also diversified requirements for the installation methods of projectors. The traditional tiled installation methods cannot be adapted to different scenarios, different locations, different spaces and other factors. Due to the changing new requirements, the vertical installation method has also become a new demand direction
[0003] The hole on the side of the projector is to allow the air inlet and outlet of the fan to form convection, so as to achieve the cooling effect of the internal laser and other high-heat components. When the customer requests to change the installation method of the projector to vertical installation (also called When installed in the side orientation), one side becomes the bottom. According to the requirements of clause 4.6.2 of the safety standard GB4943.1, the bottom of the fire protection enclosure cannot be opened or a baffle that meets the requirements is required in the state of opening Isolation is carried out to prevent combustibles from being ejected under fault conditions; in this way, if the opening in the lower part is directly closed, it will have a serious impact on the heat dissipation effect of the entire projector

Embodiment 1

[0027] Such as figure 1 As shown, in this embodiment, an intelligent adjustment structure of projection equipment includes: a first direction opening and closing mechanism, a second direction opening and closing mechanism, a stepping motor and a state detection device, through which the state detection device detects the projection The state of the device, when the projection device is in the horizontal state, the stepping motor drives the opening and closing mechanism in the second direction to close, and drives the opening and closing mechanism in the first direction to open; when the projection device is in the vertical state, through the stepping motor The motor drives the opening and closing mechanism in the second direction to open, and drives the opening and closing mechanism in the first direction to close.

[0028] In this embodiment, the ventilation hole is set as a louver opening structure, and the opening and closing of the louver opening structure can be automatic...

Embodiment 2

[0043] In this embodiment, a projection device, in addition to the conventional functional modules of the projection device, also includes the intelligent adjustment structure in Embodiment 1, the ventilation hole is set as a louver opening structure, and the louver opening can be automatically controlled by a motor. The opening and closing of the hole structure makes it possible to meet the safety requirements of no holes at the bottom when installed in the side orientation.

Abstract

The invention relates to the technical field of a projection device and discloses an intelligent adjustment structure of a projection device and the projection device. The intelligent adjustment structure comprises a first direction opening and closing mechanism, a second direction opening and closing mechanism, a stepping motor and a state detecting device. The state of the projection device is detected by the state detecting device, the second direction opening and closing mechanism is driven to be turned off by the stepping motor when the projection device is in a horizontal state, and thefirst direction opening and closing mechanism is driven to be turned on. The second direction opening and closing mechanism is driven to be turned on by the stepping motor when the projection device is in a vertical state, and the first direction opening and closing mechanism is driven to be turned off. A ventilation hole is set as a louver opening structure, and the louver opening structure can be automatically controlled to be opened and closed by the motor, and the safety requirement of a bottom without a hole can be achieved in side position installation.
