It will be apparent that the embodiments described below are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be understood that the terms "comprises" and "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It is also to be understood that the terminology used in the description of the embodiments of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of embodiments of the utility model. As used in the specification of the embodiments of the utility model and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Referring to fig. 1-5, an embodiment of the present utility model provides a device for installing a camera in an explosion-proof manner, where the device for installing a camera in an explosion-proof manner includes a housing 10 and a lens module 20, and is specifically described as follows:

the housing 10 is specifically a housing 10 of an explosion-proof terminal, and in order to improve the strength of the housing 10, the housing 10 may be made of an aluminum alloy. The housing 10 is provided with mounting holes 30, in particular mounting holes 30 for mounting the lens modules 20. The mounting holes 30 have a depth, for example, the mounting holes 30 have a depth of more than 6mm, so that a sufficient glue application width is ensured. The mounting holes 30 may be embodied as counter holes that are capable of fully receiving the lens modules 20.

The lens module 20 is an important component of the camera, and the lens module 20 is composed of lenses. Unlike the prior art in the form of a sheet, the lens module 20 of the present utility model has a height, e.g., the height of the lens module 20 is greater than 6mm, to ensure a sufficient glue application width.

In the embodiment of the utility model, the lens module 20 is disposed in the mounting hole 30, and the outer side surface of the lens module 20 and the inner side surface of the mounting hole 30 are bonded by glue 40, wherein the width of the glue 40 coating between the outer side surface of the lens module 20 and the inner side surface of the mounting hole 30 is greater than or equal to 6mm. Glue 40 may be applied specifically by dispensing.

In the embodiment of the utility model, the dispensing position of the lens module 20 is innovatively changed from the bottom surface to the side surface, and meanwhile, the height of the lens module 20 and the depth of the mounting hole 30 are designed to be larger, so that the coating width of the glue 40 can be ensured to be larger than or equal to 6mm, and the bonding strength of the lens module 20 and the shell 10 can meet the explosion-proof requirement on the premise of not changing the size (cross-sectional area) of the lens module 20.

Further, the lens module 20 is provided with a limiting portion 21 protruding outwards from the outer side, and the limiting portion 21 is embedded in the glue 40 between the outer side of the lens module 20 and the inner side of the mounting hole 30. The lens module 20 can be embedded in the glue 40 through the limiting part 21, and when explosion occurs, the pressure generated by the explosion can enable the lens module 20 to be embedded and attached with the glue 40 more tightly. Thus, the only requirements for glue 40 are water resistance and high temperature resistance.

Further, the limiting portion 21 is a flange surrounding the outer side surface of the lens module 20. The lens module 20 is cylindrical, and the flange is arranged on the periphery of the lens module 20, so that stress can be uniformly dispersed, and stress concentration is avoided.

Further, the width of the limiting part 21 is 0.1-1mm. For example, the width of the limiting portion 21 is 0.2mm, 0.5mm or 0.7mm. The limiting part 21 has a too small width and limited limiting effect. Too large a width of the limiting portion 21 will result in too small a thickness of the glue 40 at the limiting portion 21 and insufficient adhesive strength.

Further, the lens module 20 includes a first lens 22 and a second lens 23, and the first lens 22 is attached to the second lens 23. Specifically, the second lens 23 is adhered to one side of the first lens 22 by transparent glue 24. The transparent glue 24 may be embodied as OCA (Optical ClearAdhhesive, optically clear adhesive). The edge transparency of the lens module 20 is not affected after the transparent glue 24 is adopted for lamination. The material of the first lens 22 may be acrylic. The limiting portion 21 may be specifically disposed on the first lens 22.

The lens module 20 is formed by compounding a first lens 22 and a second lens 23 through transparent glue 24, the compounding process focuses on controlling bubbles after the first lens 22 and the second lens 23 are attached, and bubbles generated in the attaching process can be eliminated through a high-pressure defoaming machine.

Further, the thickness of the glue 40 between the outer side of the lens module 20 and the inner side of the mounting hole 30 is 0.1-2mm. For example, the glue 40 has a thickness of 0.2mm, 0.5mm, 1mm or 1.5mm. Too thin glue 40 has insufficient adhesion, and too thick glue 40 is prone to bubble defects. Glue 40 may be embodied as a high temperature resistant silica gel modified PUR (Polyurethane Reactive, moisture curable reactive polyurethane) hot melt adhesive.

Referring to the drawings, an embodiment of the utility model provides an explosion-proof terminal, which comprises the camera explosion-proof mounting device provided by any embodiment.

Further, the flameproof terminal further comprises a screen cover plate 50, and the screen cover plate 50 is adhered to the housing 10 of the flameproof terminal through glue 40. Since the area of the screen cover plate 50 is large enough, the explosion-proof requirement can be met after the screen cover plate is adhered by dispensing.

Further, the flameproof terminal further comprises a loudspeaker 60, and the loudspeaker 60 is connected with the shell 10 of the flameproof terminal through a fastener. The loudspeaker 60 can be firmly fixed with the shell 10 through the fastener, and the explosion-proof requirement can be met. Meanwhile, in order to improve the sealing property, a sealing ring is provided between the speaker 60 and the housing 10.

Only the lens module 20, the screen cover plate 50 and the loudspeaker 60 of the flameproof terminal provided by the embodiment of the utility model are exposed components, and can meet the flameproof requirement.

Testing

The explosion pressure is simulated by the water pressure during specific test. And opening a hole in the shell of the explosion-proof terminal, filling water pressure into the hole to 0.5MPa, and finding no water leakage. The maximum pressure reaching the explosion-proof requirement is 0.4125MPa, and the test pressure is larger than the pressure of the explosion-proof requirement, so that the explosion-proof terminal can meet the explosion-proof requirement.

Specifically, the flameproof terminal is a 4G intelligent wearable intercom video terminal, the system platform is MTK6761V/CB, and the rear camera is an 800-ten-thousand camera of an OV8856 chip.
