[0031] It can be understood that the shell 10, the catalytic carrier 20 and the electromagnetic heating element 30 constitute the main structure of the catalytic converter assembly 100, the catalytic carrier 20 and the electromagnetic heating element 30 are located in the shell 10, the shell 10 can protect the catalytic carrier 20 and the electromagnetic heating element 30, not only can prolong the service life of the catalytic carrier 20 and the electromagnetic heating element 30, but also can guarantee the catalytic effect of the catalytic carrier 20 on the gas and the heating effect of the electromagnetic heating element 30 on the catalytic carrier 20, and the electromagnetic heating element 30 is arranged on the outer peripheral surface of the catalytic carrier 20, so that the electromagnetic heating element 30 can heat the catalytic carrier 20, so that the temperature of the catalytic carrier 20 can be raised to the ideal temperature, one end of the electromagnetic heating element 30 is provided with an electrical connection part 31, the electrical connection part 31 is arranged on the outside of the shell 10, so that the electronic control unit 200 can be electrically connected with the electrical connection part 31, so that the electronic control unit 200 can control the electromagnetic heating element 30 to work, and the electromagnetic heating element 30 can heat the catalytic carrier 20, so that the catalytic converter assembly 100 can reach the best temperature.
[0032] Specifically, the electromagnetic heating element 30 can generate an alternating magnetic field by using the current through the coil, when the catalytic carrier 20 is located in the magnetic field, eddy currents will be generated inside the catalytic carrier 20, which makes the catalytic carrier 20 heat, so that the catalytic carrier 20 can quickly reach the best temperature, thereby improving the catalytic efficiency of the catalytic carrier 20, and achieving the purpose of energy saving and high efficiency of the catalytic converter assembly 100.
[0033] For example, the electromagnetic heating element 30 is a nickel alloy wire, which can ensure the rapid heating, corrosion resistance, thermal stability and reliability of the electromagnetic heating element 30, the catalytic carrier 20 is divided into a plurality of sub-catalytic carriers 20 by the steel plate, which can not only improve the durability of the catalytic carrier 20, but also improve the thermal management of the catalytic carrier 20 and reduce the back pressure, thereby ensuring the conversion of harmful substances by the catalytic carrier 20.

[0035] Thus, by arranging the catalytic carrier 20 and the electromagnetic heating element 30 in the shell 10, the electromagnetic heating element 30 is located on the outer peripheral surface of the catalytic carrier 20, so that the electromagnetic heating element 30 can heat the catalytic carrier 20, and one end of the electromagnetic heating element 30 is provided with the electrical connection part 31, which is electrically connected with the electronic control unit 200 through the shell 10, so that the electronic control unit 200 can control the electromagnetic heating element 30, and when the engine starts, the electromagnetic heating element 30 heats the catalytic carrier 20, so that the catalytic converter assembly 100 can quickly reach the optimal temperature, thereby improving the catalytic efficiency of the catalytic converter assembly 100, and avoiding the pollution of harmful substances to the atmosphere, thereby reducing the pollution of the vehicle to the air.
[0036] In particular, as shown in Figure 3 , the electromagnetic heating element 30 is in a spiral shape, which can be wrapped around the outer peripheral surface of the catalytic carrier 20, not only facilitating the increase of the heating area of the electromagnetic heating element 30 on the outer peripheral surface of the catalytic carrier 20, but also ensuring the heat dissipation between the electromagnetic heating element 30 and the catalytic carrier 20, and ensuring the lightweight design of the electromagnetic heating element 30, so that the electromagnetic heating element 30 can quickly heat the catalytic carrier 20 to the ideal temperature, thereby improving the catalytic efficiency of the catalytic converter assembly 100, and avoiding the pollution of harmful substances to the atmosphere.

[0040] That is, the gasket 41 is arranged at one end or both ends of the catalytic carrier 20 in the length direction, and the outer periphery of the gasket 41 abuts against the inner wall of the shell 10, so that the gasket 41 can limit one end or both ends of the electromagnetic heating element 30, thereby ensuring that the electromagnetic heating element 30 is still located on the outer peripheral surface of the catalytic carrier 20 when the engine starts, the surrounding member 42 is located on the outer peripheral surface of the catalytic carrier 20, and the gasket 41 is arranged at both ends of the surrounding member 42 in the length direction, so that the gasket 41 and the surrounding member 42 form a containing cavity inside, thereby facilitating the catalytic carrier 20 and the electromagnetic heating element 30 to be located in the containing cavity, and also enabling the heat of the electromagnetic heating element 30 to fill the containing cavity, thereby ensuring the temperature rise of the catalytic carrier 20. For example, the gasket 41 is a metal pad, which can ensure that the gasket 41 is located in a high-temperature environment, and the surrounding member 42 is a steel coil, which can improve the overall structural strength of the partition assembly 40, thereby ensuring the normal operation of the catalytic carrier 20.
[0041] In addition, as shown in the figure, Figures 1-3 The catalytic converter assembly 100 further comprises a temperature sensor 50, one end of the temperature sensor 50 is arranged in the containing cavity, and the other end protrudes from the shell 10 and can be electrically connected with the electronic control unit 200.

[0046] For example, when the hybrid vehicle is in a pure electric driving state, and the vehicle needs to be intervened when the power is insufficient, the electronic control unit 200 identifies the power battery power and the vehicle torque demand in advance, at this time, the inverter 600 and the actuator 700 control the electromagnetic heating piece 30 to heat the catalytic carrier 20, and when the temperature sensor 50 identifies that the containing cavity reaches the optimum temperature, the electromagnetic heating piece 30 stops heating the catalytic carrier 20, so that the catalytic efficiency of the catalytic converter assembly 100 can be improved, and the pollution of harmful substances to the atmosphere can be avoided, and the pollution of the vehicle to the air can be reduced.
