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, because the electromagnetic switch K2 and the ICR relay K1 are each of a single structure, the electromagnetic switch K2 and the ICR relay K1 need to be electrically connected with a connecting wire, and the connecting wire must also be wrapped with an insulating material, which increases the connection between the connecting wire and the car. risk of short circuits in the engine;
[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;
[0010] Fifth, the cut-in / cut-out of the current-limiting resistor is controlled by the relay winding, which is susceptible to electromagnetic interference and causes deviations in the cut-in / cut-out of the current-limiting resistor, which reduces the reliability and effect of the current-limiting resistor in suppressing the peak starting current of the motor

Abstract

The invention discloses a combined structure of an electromagnetic switch and a relay and a start-stop motor using the structure. The combined structure is characterized in that an outer shell of the switch and an outer shell of the relay are combined into a whole to form a long-barrel-shaped outer shell, an electromagnetic switch mechanism is installed on the lower portion of the long outer shell, a relay mechanism is located in the position, above the electromagnetic switch mechanism, in the long outer shell, the electromagnetic switch mechanism and the relay mechanism are positioned in a spaced mode through a wire holder, a connecting rod coaxial with a switch ejector rod and a relay ejector rod is further arranged, when a user starts to start a motor, the switch ejector rod is utilized to push the connecting rod and an relay iron core which are mutually attracted, the relay ejector rod is made to eject a relay movable contact spring to cut in a current limiting resistor, the connecting rod and the relay iron core lose the attracting force by cutting off power of a relay winding when the current limiting time is over, and therefore the relay ejector rod resets so that the current limiting resistor can be cut out. The combined structure can reduce the mounting space of the start-stop motor, reduce the short circuit risk of the motor and simplify production processes and has the advantages of being high in reliability and easy to implement.

Description

technical field [0001] The invention relates to an integrated structure of an electromagnetic switch and an ICR relay for a start-stop motor and a start-stop motor applying the 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 gear of the engine....
