Electronic relay, starter with protection function and control method thereof

Abstract

The invention discloses an electronic relay, a starter with the protection function and a control method of the starter. The electronic relay is connected to the starter, and the starter further comprises an electromagnetic switch and a motor; the electronic relay, the electromagnetic switch and the motor are sequentially connected; the electronic relay is connected with a storage battery and comprises a logic control module and a power tube, and the logic control module comprises a delay power-failure control circuit and a delay power-failure loop; the delay power-failure control circuit is connected with the delay power-failure loop, and the power tube is electrically connected with the delay power-failure loop and the electromagnetic valve; and the delay power-failure control circuit detects that the power-on time of the electronic relay is larger than the set time T0, and then, the delay power-failure control circuit controls the delay power-failure loop to be in power failure, the power tube is stopped, and the starter stops running. According to the electronic relay, secondary starting of the starter can be effectively prevented, and the top tooth protection and overreach protection functions of the starter are achieved; and the working time of the starter is shortened, the failure of parts is reduced, and the service life of the starter is prolonged.

Description

technical field [0001] The present invention relates to a starter and its electronic relay, in particular to a starter and its electronic relay capable of preventing secondary start and having a top tooth and overrunning protection function, and the present invention also relates to the starting of the protection function Machine protection function control method. Background technique [0002] figure 1 For the cross-sectional view of the existing soft mesh starter, refer to figure 1 , to illustrate the overall structure of this type of starter. exist figure 1 Among them, the output speed of the armature 11 in the motor 1 is reduced by the reduction device 2 while increasing its output rotational torque, and the motor 1 drives the drive gear 6 installed on the output shaft 5 through the one-way device 4, and then applies the starting torque to the engine . [0003] figure 2 It is a circuit diagram of a soft-mesh starter in the prior art. The circuit of this type of so...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that the relay used in the current soft mesh starter is an electromagnetic relay, which has a relatively large volume and a single function; when the user uses the starter abnormally, such as starting the engine for a long time, or energizing the starter during the working process At this time, because the relay has no protection function and cannot protect the vehicle starting system, it will reduce the service life of the starter, battery or engine flywheel ring gear, and even damage the starter, battery or engine flywheel ring gear. The soft mesh starter with protection function and its electronic relay can prevent secondary start and have the protection function of top tooth overrun
