An integrated structure of an electromagnetic switch and a relay and a start-stop motor using the integrated structure

Abstract

The invention discloses an integral structure of an electromagnetic switch and a relay and a start-stop motor applying the integral structure. The integral structure is characterized in that a switch shell and a relay shell are combined into a long cylindrical shell; both an electromagnetic switch mechanism and a relay mechanism are arranged in the long shell; a switch binding post, an input terminal, an output terminal and a diversion column are positioned on the upper part of the long shell; a current-limiting resistor is electrically connected between the input terminal and the diversion column; a relay action assembly is positioned on the middle part of the long shell; a switch action assembly is positioned on the lower part of the long shell; a relay iron core and a switch iron core are positioned on the same axis; a switch carrier rod is also coaxial with a relay iron core and a relay carrier rod; a switch movable contact spring at the upper end of the switch carrier rod is positioned close to the lower sides of the switch binding post and the output terminal; the relay carrier rod is sleeved on the switch carrier rod in a sliding way; and the upper end part of the relay carrier rod is positioned close to the lower side of the relay movable contact spring. Due to the adoption of the integral structure, the mounting space of the start-stop motor can be reduced, the short-circuit risk is lowered, and the production procedure is simplified.

Description

technical field [0001] The invention relates to an integrated structure of an electromagnetic switch and an ICR relay used for a start-stop motor and a start-stop motor applying the integrated structure. Background technique [0002] The start-stop motor, also known as the start-stop motor, is used to start the engine of the car. Existing conventional start-stop motors are composed of a motor and an electromagnetic switch. The contacts of the electromagnetic switch are connected in series on the main circuit of the motor to control the gain and loss of power of the motor. The output shaft of the motor is connected with a starter gear. When the ignition switch is turned on, the coil of the electromagnetic switch is energized and the contact of the electromagnetic switch is connected to connect the main circuit of the motor, and the motor is energized to run. On the other hand, the attraction force of the electromagnetic switch pushes the starter gear to mesh with the ring gea...

Problems solved by technology

[0006] First, because the electromagnetic switch K2 and the ICR relay K1 are all separated from the motor 25 and installed side by side in the automobile engine installation place, they take up a large space, which is not conducive to the miniaturization of the automobile engine and the operation of installation and maintenance;

[0007] Second, since the electromagnetic switch K2 and the ICR relay K1 have a single split structure, the electromagnetic switch K2 and the ICR relay K1 need to be electrically connected by connecting wires, and the connecting wires must also be wrapped with insulating materials, which increases the number of connecting wire The risk of short circuit with the car engine is also not conducive to the process simplification of the start-stop motor;

[0008] Third, due to the relatively short distance between the electromagnetic switch K2 and the ICR relay K1, their installation often requires special fixtures, which is not conducive to the simplification of the starter motor installation process, resulting in longer process time and increased process costs. The installation position of the machine on some models is extremely narrow, and it is extremely difficult to install the electromagnetic switch K2 and ICR relay K1 separately and replace the connecting wires;

[0009] Fourth, due to the split structure of the electromagnetic switch K2 and the ICR relay K1, the utilization rate of the components and materials of the electromagnetic switch K2 and the ICR relay K1 is reduced to a certain extent, resulting in a higher production cost of the start-stop motor
