[0031] The rear end of the top of the outer protection frame plate 3 is provided with an air pump 4, and the rear end of the single-chip microcomputer 2 is connected with a folding top air bag 5, and the rear end of the folding top air bag 5 is connected with the output end of the air pump 4 through a main air conveying pipe 6, and the four inner walls of the outer protection frame plate 3 are all provided with elastic folding air bags 10, and the rear end of the single-chip microcomputer 2 is externally provided with a composite air guide pipe 9, the input structure of the composite air guide pipe 9 is connected with the middle part of the main air conveying pipe 6, the composite air guide pipe 9 is internally provided with four output structures, and the four output structures are respectively extended to the internal sleeves of the four elastic folding air bags 10, and the composite air guide pipe 9 is an extension of the conveying flow channel of the main air conveying pipe 6, and can provide structural conditions for the linkage operation of the four elastic folding air bags 10 and the subsequent main air conveying pipe 6 and air pump 4;

[0032] The composite air guide pipe 9 comprises a first electromagnetic valve pipe 91, a ring pipe 92 and four shunt branch pipes 93, the first electromagnetic valve pipe 91 is installed between the middle part of the main air conveying pipe 6 and the ring pipe 92 as the input structure of the composite air guide pipe 9, the four shunt branch pipes 93 are all installed between the four elastic folding air bags 10 and the ring pipe 92 as the output structures of the composite air guide pipe 9, and the composite air guide pipe 9 provides structural conditions for the synchronous use of the four elastic folding air bags 10;

[0033] The surfaces of the two sides of the single-chip microcomputer 2 are all provided with flow guide grooves, and the number of the flow guide grooves is not less than two and is equally arranged on the two sides of the single-chip microcomputer 2, the heat dissipation area of the subsequent cooling air convection of the single-chip microcomputer 2 is increased by using the plurality of flow guide grooves, the bottom of the main air conveying pipe 6 is sleeved with a second electromagnetic valve pipe 11, and the side wall of the open port of the second electromagnetic valve pipe 11 is provided with auxiliary flow grooves aligned with the flow guide grooves, the second electromagnetic valve pipe 11 is used as a channel for releasing air in the folding top air bag 5, the self-heat dissipation effect of the single-chip microcomputer 2 is assisted by conveying air flow to the auxiliary flow grooves while maintaining the sustainable use effect of the folding top air bag 5, and a plurality of ventilation grooves 12 are arranged at the rear end of the outer protection frame plate 3 and are equally distributed on the rear end structure of the outer protection frame plate 3, thereby providing an air flow channel for the self-heat dissipation of the single-chip microcomputer 2 during operation.

[0034] The working process of the electrical equipment single-chip microcomputer protection device is as follows:

[0035] For the use of the single-chip microcomputer 2, the air pump 4 is started, air is conveyed from the output end of the air pump 4 to the inside of the folding top air bag 5 through the main air conveying pipe 6, and then the folding top air bag 5 is expanded and deformed to press the single-chip microcomputer 2, so that the single-chip microcomputer 2 moves to the development structure of the front end of the outer protection frame plate 3 under the sleeve guiding of the plurality of transition connection sleeve plates 7 and the U-shaped rods 8, until the maximum stroke of the expansion of the folding top air bag 5 and the closing of the air pump 4;

[0036] At this time, the front end operation surface of the single-chip microcomputer 2 is close to the development structure of the front end of the outer protective frame plate 3, and the user directly uses the single-chip microcomputer 2, after the use is finished, the electromagnetic valve on the second electromagnetic valve pipe 11 is opened, the air inside the folding top pressure air bag 5 is discharged through the second electromagnetic valve pipe 11 to reset, and in the process of guiding of the second electromagnetic valve pipe 11, the air fully contacts the guide grooves on the two sides of the single-chip microcomputer 2 to air-blow and heat dissipate the used single-chip microcomputer 2.

[0037] For the active air-blow and heat dissipation of the single-chip microcomputer 2, the air pump 4 is started, the output end of the air pump 4 delivers air to the inside of the folding top pressure air bag 5, the second electromagnetic valve pipe 11 and other structures through the main air pipe 6, at the same time, the electromagnetic valve on the second electromagnetic valve pipe 11 is opened, the air is delivered to the guide grooves on the two sides of the single-chip microcomputer 2 through the pipe body of the second electromagnetic valve pipe 11, so that the air fully contacts the guide grooves on the two sides of the single-chip microcomputer 2 to actively air-blow and heat dissipate the used single-chip microcomputer 2.

[0038] When the cabinet door 1 is deformed in the process of being accidentally hit, the transition connecting sleeve plate 7 and the U-shaped rod 8 synchronously receive the deformation pressure of the cabinet door 1, and the transition connecting sleeve plate 7 will be broken after receiving the pressure to a general degree due to the easy-to-break groove arranged on the transition connecting sleeve plate 7, thus the top pressure rod 15 and the pressure sensor 13 are separated from the close contact, the state of the pressure sensor 13 generating pressure data is changed into the state of the top pressure rod 15 and the pressure sensor 13 being separated, the pressure sensor 13 does not generate pressure data to express the abnormality, and the single-chip microcomputer 2 is also in a relatively independent state.

[0039] After the existing control system receives the abnormal expression, the air pump 4 and the electromagnetic valve on the first electromagnetic valve pipe 91 are synchronously started, then the output end of the air pump 4 enters the inside of the shunt branch pipe 93 through the main air pipe 6, then the air is quickly delivered to the inside of the four elastic folding air bags 10 through the four shunt branch pipes 93, so that the four elastic folding air bags 10 are quickly expanded to failure, and then the single-chip microcomputer 2 in the relatively independent state is surrounded and buffered to fully protect the single-chip microcomputer 2.
