Embodiment 1

[0029] A starter electromagnetic switch with enhanced ice-breaking capability, comprising a housing 1, inside which is provided a driving mechanism 2, a transmission mechanism 3 and a control mechanism 4;

[0030] The driving mechanism 2 includes a storage battery 201 and a motor 202. The storage battery 201 is electrically connected to the motor 202 through wires. The power output end of the motor 202 is provided with a drive gear 203. The output end of the motor 202 is provided with two sets of toggle plates 204. The two sets of toggle plates 204 surfaces are arranged parallel to each other;

[0031] The transmission mechanism 3 includes a fixed iron core 301, the outer surface of the fixed iron core 301 is wound with a suction coil 302 and a holding coil 303, the inside of the fixed iron core 301 is slidably inserted with a movable iron core 305, and the surface of the movable iron core 305 is slidably sleeved with Return spring 306, one end of movable iron core 305 is fixe...

Embodiment 2

[0039] The difference from Embodiment 1 is that the rectangular block 502 is replaced by a concave block 14 .

Embodiment 3

[0041] The difference from Embodiment 1 is that the rectangular block 502 is replaced by a hemispherical block 15 , and second strip-shaped grooves 16 are formed on one side of the hemispherical block 15 , and the second strip-shaped grooves 16 are equidistantly distributed on one side of the hemispherical block 15 .

[0042]Structural principle: a rectangular block 502 is set on the end face of the copper column 501, and an arc-shaped block 503 is set on one side of the rectangular block 502, which is changed from a flat surface to an arc surface, and the contact between it and the contact plate 308 can be changed from a surface contact to a point contact. When the latter is engaged, it can hit the ice layer, effectively improving the ice-breaking ability of the starter, and adding the first bar-shaped groove 504 on the side of the arc-shaped block 503, which can increase the contacts, increase the conductivity, and reduce the problem of difficult cold start of the engine. def...

Abstract

The invention discloses a starter electromagnetic switch capable of enhancing ice breaking capacity, which comprises a shell. A driving mechanism, a transmission mechanism and a control mechanism arearranged in the shell; the driving mechanism comprises a storage battery and a motor, the storage battery is electrically connected to the motor through a wire, a driving gear is arranged at the poweroutput end of the motor, two sets of shifting plates are arranged at the output end of the motor, and the surfaces of the two sets of shifting plates are arranged in parallel; the transmission mechanism comprises a fixed iron core; and a pull-in coil and a holding coil are wound on the outer surface of the fixed iron core. Rectangular blocks are arranged on the end faces of the copper columns. The arc-shaped block is arranged on one side of the rectangular block, the plane is changed into the arc-shaped surface, surface contact between the arc-shaped block and the contact disc can be changedinto point contact, when the arc-shaped block and the contact disc are attracted, an ice layer can be impacted, the icebreaking capacity of the starter is effectively improved, the groove is additionally formed in one side of the arc-shaped block, contacts and conductivity can be increased, and the reject ratio of engine cold starting difficulty can be reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile production, and in particular relates to a starter electromagnetic switch with enhanced ice-breaking capability. Background technique [0002] The starter electromagnetic switch is a key component of the starter, and the design quality of the electromagnetic switch directly affects the reliability of the starter. The starter electromagnetic switch has two functions, one is to connect the main circuit to make the starter rotate, and the other is to push the drive gear out through the shift fork to mesh with the flywheel ring of the engine, so the electromagnetic switch requires corresponding suction, stroke and contact. The point can reliably switch on and off large currents. [0003] When the vehicle is at normal temperature or the temperature is not very low, the starter will start normally. After the vehicle is running, it is parked at night until morning at a low temperature of -20°C, the ...
