Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, and in particular to a hybrid automobile air conditioner. Background Art

[0002] A hybrid vehicle is a vehicle that combines a traditional internal combustion engine and an electric motor as power sources. This type of vehicle uses two or more power systems to provide power to achieve lower fuel consumption and emissions.

[0003] Hybrid vehicles generally have gasoline mode, electric mode, and gasoline-electric hybrid mode. For car air conditioners, regardless of the power mode, cooling is generally provided by the evaporative core in the air conditioner box. The heating method is related to the power source. For example, in fuel mode, the air conditioner heats the air through the heat exchange between the warm air core and the engine waste heat; in pure electric mode, the air conditioner heats the air through the PTC electric heating core installed inside it.

[0004] Therefore, in order to match the heating requirements under different power modes, the air conditioning box of hybrid vehicles is often equipped with both a warm air core and a PTC electric heating core. In addition, the air conditioning box of hybrid vehicles also has a cooling evaporative core installed. Setting three sets of core components in the air conditioning box at the same time will take up more space, which will not only make the air duct layout difficult, but also make the air conditioning box structure bloated, and the compactness needs to be optimized and upgraded.

[0026] The utility model is further described below in conjunction with embodiments and drawings.

[0027] like Figure 1 and Figure 2As shown, a hybrid automobile air conditioner comprises an air conditioning box 1, wherein a main air duct a and a secondary air duct b are arranged inside the air conditioning box 1, wherein an evaporation core 2, a cold air damper 3 and an air outlet 1b are arranged in sequence on the main air duct a; one end of the secondary air duct b is connected with the main air duct a in the area between the evaporation core 2 and the cold air damper 3, and a warm air damper 4 is installed at the connecting position, and the other end of the secondary air duct b is connected to the air outlet 1b; and a warm air core 5 and an electric heating core 6 are also installed in the secondary air duct b. In order to make the two heating elements more compact, in this embodiment, the warm air core 5 and the electric heating core 6 are arranged side by side, wherein the warm air core 5 is suitable for the oil vehicle mode of the hybrid vehicle, and mainly utilizes the waste heat of the engine to exchange heat with the warm air core 5 to achieve heating, and the electric heating core 6 is suitable for the electric vehicle mode of the hybrid vehicle, and directly utilizes electric heating to achieve heating.

[0028] In this embodiment, the cold air door 3 and the warm air door 4 are both rotatably installed in the corresponding air ducts, and a driving mechanism 7 is fixedly installed on the outside of the air conditioning box 1, and the driving mechanism 7 is mainly used to drive and control the cold air door 3 and the warm air door 4 to rotate.

[0029] With this design, by arranging the warm air core 5 and the electric heating core 6 side by side, the two heating elements inside the hybrid vehicle air conditioner are installed more compactly, and the auxiliary air duct b is arranged on the main air duct a in an interlaced manner, so that the three groups of core components inside the hybrid vehicle air conditioner are installed together more compactly.

[0030] In this embodiment, the cold air damper 3 and the warm air damper 4 are both butterfly dampers, and the cold air damper 3 and the warm air damper 4 are arranged in a vertical relationship in the area between the evaporation core 2 and the warm air core 5. The butterfly damper has a small opening and closing action and occupies less space. By arranging the cold air damper 3 and the warm air damper 4 up and down, the layout of the interior of the hybrid car air conditioner is further made more compact.

[0031] like Figure 6 As shown, an air inlet channel c is formed on one side of the air-conditioning box 1, one end of the air inlet channel c is provided with an air inlet port 1a, and the other end is connected to the main air duct a. A blower 8 is also fixedly installed at the air inlet port 1a, and the blower 8 can draw outside air into the interior of the air-conditioning box 1 in the direction of the arrow in the figure.

[0032] In this embodiment, the driving mechanism 7 is connected to the cold air door 3 and the warm air door 4 through the linkage assembly 9. Under the action of the linkage mechanism 9, the driving mechanism 7 can drive the cold air door 3 and the warm air door 4 to open and close alternately. Figure 1 and Figure 2As shown, the cold air door 3 and the warm air door 4 cannot be opened or closed at the same time. In addition, under the action of the linkage mechanism 9, the driving mechanism 7 can drive the cold air door 3 and the warm air door 4 to rotate synchronously. With such a design, only one set of driving mechanism 7 is needed to synchronously realize the rotation of the cold air door 3 and the warm air door 4, and the cold air door 3 and the warm air door 4 are opened and closed alternately, which greatly reduces the overall occupied space of the driving mechanism 7, and further makes the structure of the hybrid car air conditioner more compact.

[0033] Specifically, Figure 4 As shown, the linkage mechanism 9 includes a first rotating rod 9a, a synchronous rod 9b and a second rotating rod 9c which are rotatably connected in sequence, wherein the end of the second rotating rod 9c away from the synchronous rod 9b is also hinged with the driving mechanism 7. In this embodiment, a cold air support shaft 3a is formed at the end of the cold air door 3, and a warm air support shaft 4a is formed at the end of the warm air door 4. The cold air door 3 and the warm air door 4 are rotatably installed inside the air conditioning box 1 by relying on their respective support shafts, and the end of the first rotating rod 9a away from the synchronous rod 9b is sleeved on the warm air support shaft 4a, and the middle position of the second rotating rod 9c is sleeved on the cold air support shaft 3a.

[0034] In this embodiment, the following two control methods are provided for controlling the cold air damper 3 and the warm air damper 4:

[0035] 1. Electric control

[0036] like Figure 3 and Figure 4 As shown, at this time, the driving mechanism 7 is an actuator, which is driven and controlled by a motor as a whole. In this embodiment, the output end of the actuator is connected to a swing arm 10, and the end of the swing arm 10 away from the output end of the actuator is connected to the end of the second rotating rod 9c away from the synchronization rod 9b. With this design, the actuator drives the swing arm 10 to rotate, thereby driving the second rotating rod 9c to rotate, and the synchronization rod 9b ensures that the cold air door 5 and the warm air door 6 rotate synchronously.

[0037] 2. Manual control

[0038] like Figure 5 As shown, at this time, the driving mechanism 7 is a manual actuator, which includes a rotating element 7a hinged to the second rotating rod 9c, a cable 7b is connected to the rotating element 7a, and a knob 7c is provided at the far end of the cable 7b. When the knob 7c is rotated, the cable 7b can be pulled, and the cable 7b can drive the rotating element 7a to rotate, thereby driving the second rotating rod 9c to rotate, and then through the synchronization rod 9b, the cold air damper 3 and the warm air damper 4 can be rotated synchronously.

[0039] For example Figure 1 and Figure 2As shown, the air outlet 1b is divided into a defogger air outlet 1b1, a facial air outlet 1b2 and a leg air outlet 1b3. In this embodiment, the three air outlets correspond to three different air outlet modes of the automobile air conditioner, and mode dampers 11 are rotatably installed at the three air outlets. The three mode dampers 11 operate independently of each other, thereby ensuring that the three air outlet modes are independent of each other.

[0040] In this embodiment, the three mode dampers 11 are also butterfly dampers, so that the overall space occupancy is smaller, ensuring that the overall assembly structure of the hybrid vehicle air conditioner is more compact. At the same time, the butterfly damper is also beneficial to reduce wind resistance and avoid abnormal noise.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
