[0002] At present, controllers have been widely used in many fields such as automobiles, energy storage, rail transportation, etc. Most controller shells can play a protective role, such as dustproof, waterproof and impact-proof.

[0003] Traditional controller housings are usually fixed and sealed by gluing or threaded fastening. However, most controllers need to be disassembled for maintenance during use. The controller housing fixed by the above methods requires a lot of work to complete during assembly or disassembly.

[0004] Therefore, how to achieve rapid disassembly and assembly of the shell efficiently and at low cost while ensuring its protection level is an urgent problem to be solved in the industry. Summary of the invention

At the same time, in the description of the present invention, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] The system for quickly disassembling and assembling a shell based on the negative pressure principle of the present invention comprises a shell Ⅰ1, a reversible cover plate 2, a sealing rubber pad 3, a sealing ring 4, a PCB circuit board 5, a shell Ⅱ6 and an air hole 7.

[0038] A square slot is provided in the middle of the upper part of the shell Ⅰ1. The shell Ⅰ1 on one side of the slot is connected to the flip cover 2 through a rotating shaft. The flip cover 2 can rotate around the rotating shaft and cover the slot and snap fit with the shell Ⅰ1.

[0039] The sealing rubber pad 3 is a U-shaped structure and can be fixed on the card slot of the housing Ⅰ1. Specifically, the sealing rubber pad 3 is embedded in the card slot.

[0040] The front end of the housing II 6 is provided with a strip opening, and the front end strip block of the PCB circuit board 5 can pass through the strip opening. The PCB circuit board 5 has a protective function connector, which can be fixed to the housing II 6 by means including but not limited to gluing or threaded fastening.

[0041] The top of the housing II 6 and the housing I 1 are both provided with grooves, which can be embedded with the sealing ring 4. When the housing II 6 is assembled with the housing I 1, the sealing ring 4 can be embedded in the grooves.

[0042] The housing Ⅰ1 and the housing Ⅱ6 have positioning posts and positioning holes respectively. After assembly, the positioning posts are inserted into the positioning holes, so that the housing Ⅰ1 and the housing Ⅱ6 cannot move in non-fixed directions.

[0043] An air hole 7 is also provided above the shell Ⅰ1.

[0044] The method for quickly disassembling and assembling a housing based on the negative pressure principle of the present invention includes but is not limited to housings installed in the Z direction, the X direction, and the Y direction. Taking the installation in the Z direction as an example, the method includes the following steps:

[0045] Step 1: fix the PCB board 5 with the protective function connector on the housing II 6 that fixes the PCB circuit board, including but not limited to gluing or threaded fastening.

[0046] Step 2: fix the sealing rubber pad 3 on the housing Ⅰ1 with the flip cover. The housing Ⅰ1 with the flip cover has a slot inside, which can fit the upper U-shaped structure of the sealing rubber pad 3. The flip cover 2 remains in the open state.

[0047] Step 3: Assemble the assembled housing Ⅰ1, sealing ring 4, and housing Ⅱ6. Housing Ⅰ1 and housing Ⅱ6 have grooves for embedding sealing ring 4. After assembly, sealing ring 4 is embedded in the groove. Housing Ⅰ1 and housing Ⅱ6 have positioning posts and positioning holes respectively. After assembly, the positioning posts are inserted into the positioning holes, so that housing Ⅰ1 and housing Ⅱ6 cannot move in non-fixed directions.

[0048] Step 4: Use a vacuum device with a top column to use the air hole 7 above the shell Ⅰ1 to perform vacuum. At this time, the top column supports the sealing rubber pad 3 to prevent it from being compressed and fitted onto the shell Ⅰ1.

[0049] Step 5, when the system is in a vacuum state, maintain the vacuum state, retract the top column, and make the sealing rubber pad 3 fit tightly on the shell Ⅰ1 through the vacuum action.

[0050] Step 6: Stop pumping. At this time, the system is in a negative pressure state, and the external atmospheric pressure is used to maintain the seal.

[0051] Step seven, buckle the flip cover 2 to protect the sealing rubber pad 3 to prevent foreign matter or lack of operation from causing the sealing pad 3 to fail.

[0052] Step eight, if disassembly is required, open the reversible cover 2, and use the top column to push open the sealing rubber pad 3 to create a gap between it and the shell Ⅰ1; at this time, the inside of the system is connected to the external environment, and the atmospheric pressure is consistent, so it can be disassembled and separated.
