The first damper and the second damper are used to control the opening and closing of the adjustment channel, and the third damper is used to control the outlet air angle. After the air flows into the air circulation channel and the adjustment channel respectively, they converge on the outlet side of the third damper and then are discharged.

[0029] The following specific embodiments illustrate the implementation manners of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification.

[0030] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to match the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the conditions for the implementation of this application. Therefore, they do not have any substantial technical significance.

The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope of implementation of this application.

[0031] Please refer to Figures 1 to 5 , this application exemplarily provides an air conditioner temperature adjustment device, including:

[0032] An execution seat 15 is arranged on the HVAC assembly 2. An execution member is rotatably arranged on the execution seat 15. An air circulation flow channel 9 is arranged on the HVAC assembly 2;

[0033] An air door assembly is arranged on the execution member. The air door assembly includes a first air door 3, a second air door 4, and a third air door 5. An adjustment flow channel 7 is formed between the first air door 3, the second air door 4 and the HVAC assembly 2. The adjustment flow channel 7 is communicated with the air circulation flow channel 9. The first air door 3 and the second air door 4 are used to control the opening and closing of the adjustment flow channel 7. The third air door 5 is used to control the air outlet angle. After the airflows enter the air circulation flow channel 9 and the adjustment flow channel 7 respectively, they converge on the air outlet side of the third air door 5 and then are discharged.

[0034] In the air conditioner temperature adjustment device provided by this application, an adjustment flow channel 7 is formed between the first air door 3, the second air door 4 and the HVAC assembly 2 to shunt the airflows. When temperature adjustment is required, the execution member rotates on the execution seat 15 to open the second air door 4 and the second air door 4. The airflows enter the air circulation flow channel 9 and the adjustment flow channel 7 respectively. The airflow in the air circulation flow channel 9 is output as a refrigerated airflow with a lower temperature after refrigeration, and the airflow in the adjustment flow channel 7 is output as a normal-temperature airflow. The normal-temperature airflow and the refrigerated airflow converge on the air outlet side of the third air door 5 and then are discharged. The normal-temperature airflow output through the adjustment flow channel 7 compensates the temperature of the refrigerated airflow output through the air circulation flow channel 9 to complete the adjustment of the air outlet temperature of the air conditioner.

[0035] In this embodiment, as Figure 5As shown, the actuator is a cam disk 16. The cam disk 16 is connected to the first air damper 3 and the second air damper 4 through a lever 18, and the cam disk 16 is connected to the third air damper 5 through a connecting rod 20. Specifically, a first guide groove 17 and a second guide groove 19 are formed on the cam disk 16. The lever 18 is movably arranged on the first guide groove 17, and the connecting rod 20 is movably arranged on the second guide groove 19. When the cam disk 16 rotates on the actuator seat 15, the lever 18 moves on the first guide groove 17 to control the opening and closing of the first air damper 3 and the second air damper 4 for the regulating flow channel 7, and the connecting rod 20 moves on the second guide groove 19 to control the third air damper 5 to adjust the air outlet angle.

[0036] In this embodiment, please refer to Figures 2 to 5 , a blocking portion 6 is provided on the third air damper 5, and a first air outlet 12 and a second air outlet 13 are provided on the HVAC assembly 2. The air outlet angles of the first air outlet 12 and the second air outlet 13 are different. The blocking portion 6 blocks in front of the first air outlet 12, and the air flow is blocked and discharged from the second air outlet 13, or the blocking portion 6 blocks in front of the second air outlet 13, and the air flow is blocked and discharged from the first air outlet 12. By adjusting the air outlet angle of the third air damper 5, the air flow is discharged from different air outlets to meet the air outlet requirements at different positions in the vehicle. Specifically, when the third air damper 5 moves close to the regulating flow channel 7 to make the blocking portion 6 block in front of the first air outlet 12, the air outlet side of the third air damper 5 is the side away from the regulating flow channel 7 at this time. When the third air damper 5 moves away from the regulating flow channel 7 to make the blocking portion 6 block in front of the second air outlet 13, the air outlet side of the third air damper 5 is the side close to the regulating flow channel 7 at this time.

[0037] In another embodiment, as Figures 2 to 4 shown, the present application further provides an HVAC assembly, including:

[0038] A blower motor 8 for generating an air flow to provide an air source;

[0039] An evaporator 10 for absorbing heat in the air flow for cooling;

[0040] A heating device 11 for providing a heat source;

[0041] And the air-conditioning temperature regulating device 1 as above.

[0042] It should be noted that when using the vehicle in summer, spring or autumn, in order to meet the comfort of riding, it is usually necessary to turn on the air conditioner for temperature adjustment to ensure that the temperature inside the vehicle is appropriate. However, as the perceived temperature drops, in order to maintain the perceived comfort, it is necessary to turn on the heating device 11 for temperature compensation. The heating device 11 mainly provides heat source air for heating the vehicle in winter. The energy consumed by the heating device 11 is relatively large. In the temperature adjustment conditions in summer, spring or autumn, using the heating device 11 for temperature compensation will inevitably increase the vehicle energy consumption of new energy vehicles, affect the vehicle range, and increase the vehicle use cost.

[0043] In the above embodiment, as Figure 2 shown, when temperature adjustment is not required, the first air door 3 and the second air door 4 are both closed at the same time. The air flow generated by the blower motor 8 enters the air circulation channel 9. The air flow passes through the evaporator 10 and the heating device 11 in sequence and then is discharged. When the vehicle air conditioner does not need to adjust the temperature, the adjustment channel 7 is closed by the first air door 3 and the second air door 4 and is not communicated with the air circulation channel 9. The air flow can only enter the air circulation channel 9, pass through the evaporator 10 for cooling, and then pass through the heating device 11. In the refrigeration condition, the heating device 11 does not need to be turned on and only allows the air flow to pass through, and finally is discharged from the air outlet.

[0044] In the above embodiment, as Figure 3 shown, when temperature adjustment is required, the first air door 3 and the second air door 4 are both opened at the same time. The air flow generated by the blower motor 8 enters the air circulation channel 9 and the adjustment channel 7 respectively. The air flow converges on the air outlet side of the third air door 5 and then is discharged. When the vehicle air conditioner needs to adjust the temperature, the air flow enters the air circulation channel 9 and the adjustment channel 7 respectively. Shunted by the adjustment channel 7, the air flow entering the air circulation channel 9 becomes less, and the refrigerating gas passing through the evaporator 10 becomes less. The air flow temperature in the adjustment channel 7 is normal temperature. The normal temperature air flow flowing out of the adjustment channel 7 and the refrigerating air flow flowing out of the air circulation channel 9 are mixed in the air mixing area of the third air door 5. The mixed air flow is then discharged from the air outlet to achieve the adjustment of the temperature inside the vehicle. Specifically, by adjusting the opening angles of the first air door 3 and the second air door 4, the air flow size entering the adjustment channel 7 and the air flow size flowing out of the adjustment channel 7 can be changed, and air outlet at different temperatures can be realized to meet the temperature adjustment requirements.

[0045] In this embodiment, a return air heat dissipation port 14 is provided on the blower motor 8. The return air heat dissipation port 14 is communicated with the adjustment channel 7. The return air heat dissipation port 14 can dissipate heat from the blower motor 8. At the same time, when the air flow enters the adjustment channel 7, part of the air flow will enter the return air heat dissipation port 14. The air flow will take away the heat generated by the blower motor 8 to achieve heat dissipation. The temperature of the air flow will increase. As a hot air source, the air flow is newly generated from the blower motor 8 and enters the air circulation channel 9 and the adjustment channel 7, improving the temperature adjustment efficiency.

[0046] In this embodiment, as Figure 4 shown, when the first air damper 3 is opened and the second air damper 4 is closed, the air flow generated by the blower motor 8 enters the air circulation channel 9 and the adjustment channel 7 respectively. The air flow in the adjustment channel 7 is discharged from the return air heat dissipation port 14. The air flow in the air circulation channel 9 is discharged after passing through the evaporator 10 and the heating device 11 in sequence. In the case of a relatively small temperature adjustment requirement, the air flow can be split through the adjustment channel 7, and the air flow in the air circulation channel 9 becomes smaller, which can reduce the air output volume, thereby realizing the adjustment of the air output volume. When the air output volume decreases, the body feeling temperature of the vehicle occupants can also be correspondingly increased.

[0047] In another embodiment, the present application also provides an automobile, including the above-mentioned HVAC assembly.

[0048] In summary, in the air-conditioning temperature adjustment device provided by the present application, an adjustment channel 7 is formed between the first air damper 3, the second air damper 4 and the HVAC assembly 2 to split the air flow. When temperature adjustment is required, the actuator rotates on the actuator seat 15 to open the second air damper 4 and the second air damper 4. The air flow enters the air circulation channel 9 and the adjustment channel 7 respectively. The air flow in the air circulation channel 9 is output as a relatively low-temperature cooling air flow after refrigeration, and the air flow in the adjustment channel 7 is output as a normal-temperature air flow. The normal-temperature air flow and the cooling air flow are discharged after converging on the air outlet side of the third air damper 5. The normal-temperature air flow output through the adjustment channel 7 compensates the temperature of the cooling air flow output from the air circulation channel 9 to complete the adjustment of the air outlet temperature of the air conditioner. In the temperature adjustment working conditions in summer, spring or autumn, there is no need to turn on the heating device 11 for temperature compensation, which can effectively reduce energy consumption, improve endurance and reduce the vehicle use cost.

[0049] The above embodiments are only used to exemplarily illustrate the principle and efficacy of the present application, rather than to limit the present application. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present application should still be covered by the claims of the present application.
