This motion component 442 belongs to the prior art and can be obtained by purchasing from outside.

[0035] The air inlet of the present invention realizes different working modes through different connection modes with the defrost air outlet, the face-blowing air outlet and the first rear foot-blowing air outlet. Specifically, the air inlet is only connected with the face-blowing air outlet to realize the face-blowing working mode, the air inlet is simultaneously connected with the face-blowing air outlet and the first rear foot-blowing air outlet to realize the face-blowing and foot-blowing working mode, the air inlet is only connected with the first rear foot-blowing air outlet to realize the foot-blowing working mode, the air inlet is simultaneously connected with the first rear foot-blowing air outlet and the defrost air outlet to realize the foot-blowing and defrost working mode, and the air inlet is only connected with the defrost air outlet to realize the defrost working mode.

[0036] like Figure 2 As shown, the distribution box module of this embodiment further includes a temperature damper group 51 and a second power member 52, the second power member 52 is a motor, the temperature damper group 51 is located between the evaporator 2 and the heating element 3 and is arranged face to face with the evaporator 2 and the heating element 3, the second power member 52 is arranged on the third housing 13, the temperature damper group 51 is connected to the output end of the second power member 52, and the temperature damper group 51 is configured to be closed when the evaporator 2 is working and open when the heating element 3 is working. Specifically, the temperature damper group 51 and the second power member 52 can be shared on different types of vehicles to reduce the R&D time and R&D cost of the distribution box module, which is conducive to the modular setting of the distribution box module.

[0037] Specifically, Figure 4 As shown, the distribution box module of this embodiment further includes a rack 53 and a gear shaft 54, the rack 53 is in transmission connection with the second power member 52, the gear shaft 54 ​​is meshed with the rack 53, and the temperature damper group 51 is arranged on the gear shaft 54. Figure 4As shown, the gear shaft 54 ​​of this embodiment includes a first gear shaft 541 and a second gear shaft 542, and the first gear shaft 541 and the second gear shaft 542 are both engaged with the rack 53. The temperature damper group 51 includes a first temperature damper group 511 and a second temperature damper group 512. The first temperature damper group 511 is arranged on the first gear shaft 541, and the second temperature damper group 512 is arranged on the second gear shaft 542. The first temperature damper group 511 includes two coaxially arranged and left-right symmetrical temperature dampers, and the second temperature damper group 512 includes two coaxially arranged and left-right symmetrical temperature dampers. The two temperature dampers of the first temperature damper group 511 and the two temperature dampers of the second temperature damper group 512 are symmetrically arranged in the upper and lower parts. This arrangement can reduce the space required for the temperature dampers during rotation, which is beneficial to the miniaturization of the size of the distribution box module in the forward direction of the vehicle, so that the structure of the distribution box module is more compact.

[0038] Specifically, when heating, Figure 4 The schematic diagram of the temperature damper group 51 in the open state, at this time, the air entering through the air inlet flows through the evaporator 2, the gap between the first temperature damper group 511 and the second damper group, and then is heated by the indoor condenser 31 and the PTC heater 32. At this time, the temperature of the air rises, and then it is blown out through the corresponding defrost vents, face vents, first rear foot vents or second rear foot vents. When cooling, the air entering through the air inlet is cooled in the evaporator 2 to form low-temperature air, and the second power member 52 rotates. Figure 4 The first damper group moves downward and the second damper group moves upward to prevent the low-temperature air from rising in temperature again when passing through the indoor condenser 31 and the PTC heater 32, thereby reducing the refrigeration efficiency of the distribution box. That is, at this time, the low-temperature air formed by cooling down the evaporator 2 does not need to pass through the indoor condenser 31 and the PTC heater 32 for heating, but is directly blown out from the corresponding defrost air outlet, face air outlet, first rear foot air outlet or second rear foot air outlet.
