Problems solved by technology

[0003] The problem with existing relays with an arc extinguishing mechanism is that the arc extinguishing method of the relay is to attract and eliminate the generated arc, the arc is still generated, and the risk of damage still exists; secondly, if it is necessary to ensure that the arc is attracted and eliminated, the relay The machining accuracy and assembly accuracy requirements are improved, and the production cost is increased

Embodiment Construction

[0034] see figure 1 , figure 1 The structural diagram of the upper cover is hidden for the electrical component assembly of the electric vehicle. The laminated busbar assembly 100, the electrical component 300 and the insurance seat 400 are installed at a specific position in the housing 200. The insurance seat 400 supplies power to multiple electrical components 300 and provides For overload protection, the metal bars on the laminated busbar assembly 100 are connected to multiple electrical components 300 to realize the electrical connection between the multiple electrical components 300 .

[0035] see figure 2 , figure 2It is an exploded view of the structure of the laminated busbar assembly 100. The laminated busbar assembly 100 includes an insulating board 10 and a relay 20. Metal bars 11 are installed and distributed on the insulating board 10. A control insulating board is stacked and installed under the insulating board 10. 50 , the relay 20 is installed on the ins...

Abstract

A relay switch circuit disclosed by the invention comprises a control circuit and a relay, wherein the control circuit sends a first control signal to the relay; the relay witch circuit also comprises a time-delay circuit, a first switch element, a second switch element and a voltage regulation element; the relay is connected with the first end of the first switch element while the second end of the first switch element is grounded; the first end of the voltage regulation element is connected with the first end of the first switch element while the second end of the voltage regulation element is connected with the first end of the second switch element, and the second end of the second switch element is grounded; the control circuit sends a second control signal to the time-delay circuit; the time-delay circuit sends a third control signal to the first switch element; and the time-delay circuit sends a fourth control signal to the second switch element. Arc-extinction starting and arc-extinction stopping of the relay are realized by the relay switch circuit through the control circuit, the time-delay circuit, the first switch element, the second switch element and the voltage regulation element; and meanwhile, the first switch element is subjected to anti-breakdown protection.

Description

technical field [0001] The invention relates to the field of electrical components, in particular to a relay switch circuit with a precharging circuit, a control method for the relay switch circuit and an electric vehicle electrical component assembly including the relay switch circuit. Background technique [0002] The prior art is a relay with an arc extinguishing mechanism for the power supply of an electric vehicle. This relay has a housing with an arc extinguishing mechanism inside the housing. The arc extinguishing mechanism includes an arc extinguishing element and two The arc starting element and a ground wire for connecting with the ground wire. The arc extinguishing element is a diode, a resistor or an RC circuit; the arc starting element is a conductor electrically connected to the power supply connection of the arc extinguishing element. Among the two arc starting components, the first arc starting component is electrically connected to the discharge static conta...
