Multifunctional starter protector

Abstract

The invention relates to a multifunctional starter protector, and belongs to the technical field of vehicle start protecting equipment. The multifunctional starter protector is composed of a protector body and a 20 to 30 second delay circuit, and is characterized in that the protector body comprises the 20 to 30 second delay circuit, a top tooth condition monitoring circuit, a voltage monitoring circuit for proofing secondary start and an anti-exceeding beyond voltage monitoring circuit. Overheating burning incidents of a coil due to nonconductive electromagnetic switch contacts can prevented effectively. After a vehicle starts, automatic determination can be performed and electricity can be switched off, and beyond operating time of an engine can be reduced effectively, and service life of the engine can be prolonged; milling failures caused by accidental energization of the secondary false start during operation of the vehicle can be prevented; the multifunctional starter protector still has multiple protecting functions of limiting time of utmost 20 to 30 seconds for single starting operation and the like; additional lead increase is omitted, structure is simple, and producing and mounting are facilitated.

Description

technical field [0001] The invention relates to a multifunctional starter protector, which belongs to the technical field of vehicle starting protection equipment. Background technique [0002] Since the starter is the electrical device with the largest instantaneous power on the vehicle, it is very easy to generate heat and burn out, so the starter on the vehicle is generally equipped with a protector at present. The time-limited protector can limit the operation that takes too long to start a single time to protect the starter, but after the vehicle is started, it cannot be forced to cut off the power quickly, and the starter is easily damaged or even damaged by the engine's high-speed anti-drag; and the time limit The type protector cannot protect the secondary energization caused by misoperation during vehicle operation, and the result will cause damage to the drive gear and the flywheel teeth of the engine, thereby affecting the normal meshing of the two; the widely use...

Problems solved by technology

[0003] The purpose of the present invention is to provide an installation that does not require additional lead wires, has a simple structure, is easy to manufacture and install, and can prevent the coil of the flexible meshing starter from being overheated and burned due to the failure of the electromagnetic switch contacts; Automatically judge and cut off the power in time after landing; it can avoid the milling fault caused by the accidental power-on of the starter due to the second wrong start operation during the running of the vehicle, effectively prolonging the service life of the starter; solving the problem of the flexibility of various existing protectors When the meshing starter is blocked, it will be burnt within a few seconds and cannot provide protection; or additional lead wires need to be added during installation; or the power cannot be cut off quickly after the vehicle is started, resulting in damage to the starter. The service life is short; or the multi-function starter protector that causes damage to the drive gear and engine flywheel teeth due to misstarting operation during vehicle operation and cannot mesh normally
