In the present utility model, unless explicitly stated and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly. For example, the two parts can be fixedly connected, detachably connected or integrated; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

In the present utility model, unless expressly stated or limited otherwise, the meaning of a first feature being "on" or "off" a second feature, and the like, is that the first and second features are either in direct contact or in indirect contact through an intervening medium.

As mentioned in the background, the camera module in the projector is usually fixed directly to the front cover or fixed to the front cover by means of a bracket. In the process of using the projector, components such as an optical-mechanical assembly and a power supply inside the projector generate heat, and a heat dissipation hole is usually formed in the front cover to dissipate heat. Therefore, the camera module fixed on the front cover can influence the shape of the radiating holes in the front cover and the appearance of the front cover. If the front cover is provided with the corresponding blind hole Kong Cheng for heat dissipation at the position corresponding to the fixed camera module, the shape of the heat dissipation hole still changes, so that the area of the heat dissipation hole presents an inconsistent appearance. Therefore, the appearance effect of the whole machine can be influenced.

Based on this, in order to improve the above-mentioned problems, the embodiment of the utility model provides a housing, which improves the appearance of the front cover by changing the assembly mode of the camera module, so as to improve the appearance effect of the whole machine.

For convenience of explanation, before describing a specific structure in the embodiment of the present utility model, the structure of the housing provided in the embodiment of the present utility model will be described with reference to the related drawings.

The direction corresponding to the front is the rear, i.e., the direction in which the front cover 120 faces one side of the housing 110. The illustrations illustrated hereinafter follow this definition and are not repeated. It is to be understood that the above definitions are provided for illustrative purposes only and are not to be construed as limiting the present utility model. It is to be understood that the above definitions are provided for illustrative purposes only and are not to be construed as limiting the present utility model.
