As shown in fig. 1, the present utility model provides an inorganic boxed adjustment structure of an aerospace controller, comprising: a housing 1 and an adjusting frame 2. The first side and the second side opposite to the shell 1 are fixedly connected with the first side and the second side opposite to the adjusting frame 2 respectively. The inside of the third side of the housing 1 adjacent to the first side is used for mounting a motherboard 5, and the adjusting bracket 2 is used for mounting a daughter board 6. The inner walls of the first side face and the second side face are respectively provided with a first conversion block 3, and the first side edge and the second side edge are respectively provided with a second conversion block 4. The second adapter block 4 can slide along a vertical direction (the direction indicated by an S arrow in fig. 1) relative to the first adapter block 3, and the position of the adjusting frame 2 is adjusted so that the motherboard 5 is in butt joint with the daughter board 6.

In particular, as shown in fig. 2, in the trend of the gradual function integration and downsizing of the controller, it is particularly important to realize signal communication between the respective control boards 7. For the steamer type control design, the signal transmission between the control boards is generally realized by connecting the control boards from the top layer to the bottom layer through the inter-board connector 8. In this solution, the occupation defined for the core of each board-to-board connector is from the topmost control board to the bottommost control board, so that more board-to-board connector cores and thus more board-to-board connectors are required to transmit the same signal. In addition, in order to avoid occupation of core point definition, the inter-board connectors need to be staggered and inserted between the control boards so as to reduce the required quantity of the core points of the inter-board connectors. However, the misalignment of the board-to-board connector positions of the control boards having the same functions requires different layout patterns for the board-to-board connector core points, and it is difficult to realize the control board interchange for the production and serialization of the controller. Therefore, the data transmission scheme between the sub-boards realized by the motherboard is increasingly applied to the design of the controller.

In the case scheme of the slide rail, the mother board is fixed, the daughter boards are adjusted, the slide rail is utilized to insert each daughter board into the mother board, and the daughter boards are locked by tightening locking bars after the insertion is completed. However, the product structure of the scheme is complex, so that a rigid-flexible board inorganic case design scheme of the controller is generally adopted on the basis of the scheme. In the rigid-flex board inorganic case design scheme, the motherboard needs to adopt the rigid-flex board, but the rigid-flex board has larger constraint on the PCB design, lower vibration adaptation condition and higher cost. In the controller scheme for realizing data transmission between the daughter boards through the motherboard, the motherboard and the daughter boards need to be ensured to be successfully plugged. Because of the requirement of the plugging error of the backboard connector, the positions of the mother board and the daughter board need to be relatively adjustable so as to ensure that the mother board and the daughter board are successfully plugged. In the case design of the slide rail, the position of the daughter board can be adjusted before the daughter board and the locking bar are locked so as to adapt to the plugging error of the backboard connector. In the rigid-flexible board inorganic case design, a motherboard is fixed, and the motherboard and a daughter board are ensured to be successfully inserted through the rigid-flexible board.

Because of the electromagnetic shielding and waterproof requirements of the controller, the processing of threaded holes penetrating through the shell on the shell structure should be avoided as much as possible. In this embodiment, the motherboard is fixed on the housing, and the daughter board (i.e., the daughter board control board) is fixed on the adjustment frame. Through setting up first transfer piece at the casing medial surface, the alignment jig passes through first transfer piece and second transfer piece and casing fixed connection to accessible first transfer piece and second transfer piece relative slip realize along the casing vertical direction (the directional direction of S arrow in fig. 1) relative casing slip, realized the adjustment of alignment jig vertical direction, thereby realized the relative position of adjustment daughter board and mother board. The dimension error of the daughter board in the board thickness direction is larger than the insertion error of the back board connector, so that the daughter board and the mother board are successfully inserted.

According to the inorganic box-type adjusting structure of the space flight controller, provided by the embodiment, on the premise that the problem of plugging of a motherboard and a daughter board is solved, the inorganic box-type of the controller is realized, so that the controller is compact in structure, the size of the controller is reduced, the rigid flexible board is avoided, the machining precision of each machining part is reduced, and meanwhile serialization of the controller is facilitated.
