One group of electronics module of Camera postures, because its change to temperature is more sensitive, generally by itself and other electronic components
Isolated, reduce the temperature change influence that heat transfer is brought.It is main by two class formation designs at present：1. utilize one group of list
Only housing cavity, i.e., the chamber being made up of module upper casing 50 and module lower casing 80, Inertial Measurement Unit 70 is fitted into wherein,
Foam class auxiliary material 60 is enclosed with around Inertial Measurement Unit 70, this module is then fixed to a certain position, such as Fig. 1 in fuselage
It is shown；2. individually isolate a part of region on pcb board (printed circuit board), Inertial Measurement Unit and other component areas are allowed
Domain separation, then gluing or the heat-insulated foam of covering are thermally insulated in this cell module.
The major defect of above-mentioned two class formation is：
Scheme 1：Independent structure housing unit is main by two aspect defects：A, complicated, module assembling is complicated, b, and by
It is to organize separately to be attached on housing in module, assembling deviation is produced in an assembling process, causes module and Camera relative position one
Cause property is relatively low.
Scheme 2：Isolate Inertial Measurement Unit on pcb board, this scheme major defect is because Inertial Measurement Unit still with
The heating that pcb board has the component on connection physically, main PCB still can easier be transmitted to Inertial Measurement Unit,
And because simple gluing or heat-insulated foam can not uniformly completely cut off surrounding environment heat, cause the heat-insulated effect of Inertial Measurement Unit
Fruit is not uniform consistent enough.
This current two classes design, preferable balance is not reaching on heat-insulated and fixed, in the case, is proposed new
The heat-insulated fixed design of Inertial Measurement Unit of type is very necessary.

Unit is connected, and the Camera modules are located at the top of the Inertial Measurement Unit and are connected with the housing.
The bottom of the chamber is provided with the position limiting structure for being used for positioning the support Inertial Measurement Unit.
The position limiting structure is the limit rib being connected with the housing, and the two ends of the Inertial Measurement Unit pass through the limit
Position muscle positioning support.
The hot molten column is four and is inserted in respectively in the through hole that the corner of the Inertial Measurement Unit is provided with, four
The upper end of the individual hot molten column is integrated by hot melting way with Inertial Measurement Unit hot melt.
The chamber is the cavity of surrounding closed top opening.
The housing includes the upper shell and lower house being detachably connected, and the chamber is arranged at the bottom of the lower house
Portion.
