Disassembly prevention structure for intelligent throttle controller housing

Abstract

The invention discloses a disassembly prevention structure for an intelligent throttle controller housing. The controller housing is assembled on a throttle valve body through a screw, and the end face, making contact with the throttle valve body, of the controller housing is provided with a vertical buckle which passes through the throttle valve body. The throttle valve body is provided with a buckle via hole passing through the buckle. A disassembly prevention separator for protecting the buckle is disposed below one end, extending out of the throttle valve body, of the buckle, and is fixedly disposed on the throttle valve body. Moreover, an opening for allowing the buckle to come out is disposed between the disassembly prevention separator and the throttle valve body. The structure canguarantee that the throttle valve body is corresponding to the controller in the production and detection process, also can accurately distinguish whether the throttle is disassembled or not in the subsequent aftersales process, guarantees the work precision of a product, and facilitates subsequent aftersales services.

Description

technical field [0001] The invention relates to the technical field of throttle controller protection, in particular to an anti-disassembly structure for a throttle controller housing. Background technique [0002] As the function design of the circuit board becomes more and more complex, the protection of the circuit board is becoming more and more important, especially in the intelligent electronic throttle, not only the circuit is complicated, but also the relative position of the Hall chip inside the throttle to the magnetic steel is also very important. Precise fixing is required, so dismantling the controller shell at will will not only cause damage to the circuit, but also cause the position of the Hall chip and the magnetic steel to shift, resulting in inaccurate opening of the throttle valve, which makes the engine unstable under certain working conditions. Stable work, so the intelligent throttle valve must ensure the one-to-one correspondence between the throttle ...

[0002] As the function design of the circuit board becomes more and more complex, the protection of the circuit board is becoming more and more important, especially in the intelligent electronic throttle, not only the circuit is complicated, but also the relative position of the Hall chip inside the throttle to the magnetic steel is also very important. Precise fixing is required, so dismantling the controller shell at will will not only cause damage to the circuit, but also cause the position of the Hall chip and the magnetic steel to shift, resulting in inaccurate opening of the throttle valve, which makes the engine unstable under certain working conditions. Stable work, so the intelligent throttle valve must ensure the one-to-one correspondence between the throttle valve body and the controller in the relative position during the original production inspection process

In addition, since dismantling the throttle valve by yourself will cause the original factory technicians to fail to analyze the cause of the failure, the aftermarket requirement for the smart throttle valve in the aftermarket is that customers must not disassemble the throttle valve by themselves, otherwise they will not be able to settle the claim

[0003] At present, the controller casing is usually assembled with screws. The anti-disassembly method is to apply red paint on the top of the screw. When identifying whether it has been disassembled, check whether the red paint on the top of the screw is damaged; however, the screw’s The red paint on the top is remedial and if intentional removal can be concealed by reapplying the red paint so true identification cannot be achieved
