Problems solved by technology

[0003] The ventilation holes of the existing projector equipment are set on the side of the equipment, and there are no openings on the upper cover and the bottom. This opening scheme can meet the requirements of the safety regulations that the bottom has no holes and does not need to be tested during normal installation and ceiling installation. When the equipment needs to be installed in the side orientation, the ventilation hole on the side becomes the bottom opening, which will not meet the requirements of safety regulations, so the side orientation installation cannot be performed

Embodiment 1

[0028] Such as figure 1 As shown, in this embodiment, a multi-directional installation projection device includes: a ventilation structure, the ventilation structure includes: a vent and a movable part arranged at the vent, when the projection device is installed in a side orientation , the ventilation direction of the ventilation structure is adjusted through the movable part.

[0029] In this embodiment, the position of the vent is adjusted by setting movable parts at the vent, so that the safety requirement of no holes at the bottom can be met even when installed in the side orientation, and the effect of multi-directional installation of the projection device is achieved.

[0030] Such as Figure 2-3 As shown, in this embodiment, the vent includes a bottom vent and a side vent, the movable part is a foldable non-porous structure, and one end of the foldable non-porous structure is fixedly connected to the bottom vent and side vents, when the projection equipment is insta...

Embodiment 2

[0035] Such as Figure 4-5 As shown, in this embodiment, the vent is an arc vent, and the movable part includes: a first arc structure and a second arc structure, and the arc vent is connected to the first arc The structure and the second arc structure are concentric structures; when the projection device is installed normally, the first arc structure and the second arc structure cover the upper section and the lower section of the arc vent respectively; when the projection equipment When installed in a side orientation, both the first arc structure and the second arc structure cover the middle section of the arc vent.

[0036] Figure 4 It is a schematic diagram of the ventilation structure when the projection equipment is installed normally, Figure 5 It is a schematic diagram of the ventilation structure when the projection device is installed in the side orientation. When installed in the side orientation, the middle section of the arc vent is facing downward as the bott...

Embodiment 3

[0041] Such as Figure 6-7 As shown, in this embodiment, the vents include bottom vents and side vents, both of which are louver structures. When the projection device is installed normally, the louvers on the bottom vents When the projection device is closed, the louvers of the side air vents are opened; when the projection device is installed sideways, the louvers on the bottom air vents are opened, and the louvers of the side air vents are closed.

[0042] In this embodiment, using the switch characteristics of the louver, the blade width of the louver structure is greater than the distance between the blade shafts, such as Figure 6 As shown, the distance between the blades of the louver is d, and the width of the blade is w, which needs to satisfy w>d. When the louver is closed, the blades overlap each other, and there is no gap between the blades, so as to meet the fire safety requirements.

[0043] Such as Figure 8-9 As shown, as another embodiment, the vent also inc...

Abstract

The present invention relates to the technical field of projection equipment, and discloses a projection equipment installed in multiple directions, including: a ventilation structure, the ventilation structure including: a vent and movable parts arranged at the vent, when the projection device is installed sideways At the same time, the ventilation direction of the ventilation structure is adjusted through the movable parts, and the position of the vents is adjusted by setting the movable parts at the vents, so that when installed in the side orientation, the safety requirements of no holes at the bottom can also be met.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a projection equipment installed in multiple directions. Background technique [0002] The projector is a high-heat-generating device that needs to be cooled by forced convection. In the scheme using forced convection, ventilation holes are usually installed on the projector. The position of the ventilation holes is generally fixed with the completion of the projector design. . [0003] The ventilation holes of the existing projector equipment are set on the side of the equipment, and there are no openings on the upper cover and the bottom. This opening scheme can meet the requirements of the safety regulations that the bottom has no holes and does not need to be tested during normal installation and ceiling installation. When the equipment needs to be installed in the side orientation, the ventilation holes on the side will become openings at the bottom, which will...
