Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a high-stability automotive air conditioning damper actuator motor. Background Technology
[0002] Automotive air conditioning damper actuator motors are used to control the opening and position of the dampers in automotive air conditioning systems to adjust the air volume, air direction, and temperature. During vehicle operation, vehicles face various complex operating conditions, such as vibrations from bumpy roads, changes in ambient temperature, and interference from electrical systems. Existing automotive air conditioning damper actuator motors are not stable enough under these complex conditions, therefore a highly stable automotive air conditioning damper actuator motor is needed.
[0003] However, due to the poor heat dissipation and temperature control capabilities of the high-stability automotive air conditioning damper actuator motor in the existing technology, it is not convenient to adjust the temperature of the actuator motor according to the usage needs during actual use. It is also not convenient to dissipate the heat generated by the actuator motor in a timely and effective manner. Long-term high-temperature use can easily affect its operational stability. Utility Model Content

[0005] The purpose of this utility model is to provide a highly stable automotive air conditioning damper actuator motor to solve the problem mentioned in the background art that the existing technology is not convenient for adjusting the temperature of the actuator motor according to the usage needs.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-stability automotive air conditioning damper actuator motor, comprising an aluminum alloy motor housing, a motor body fixedly installed on one side inside the aluminum alloy motor housing, a motor shaft fixedly installed at the output end of the motor body, the motor shaft extending to the outer end of the aluminum alloy motor housing, a protective shell fixedly installed on the side of the aluminum alloy motor housing away from the motor shaft, and heat dissipation fins fixedly installed on the side of the motor body away from the motor shaft.
[0008] Preferably, a support rod is fixedly installed inside the protective housing, a micro motor is fixedly installed in the middle of the support rod, a fan blade is fixedly installed at the output end of the micro motor, and a ventilation mesh is opened on the side of the motor aluminum alloy shell near the protective housing.
[0009] Preferably, a limiting rubber pad is fixedly installed inside the aluminum alloy housing of the motor, the limiting rubber pad is attached to the outer end of the motor body, and an exhaust mesh is provided at the top of the aluminum alloy housing of the motor.
[0010] Preferably, a heating wire is fixedly installed inside the protective housing on the side away from the micro motor, and a temperature sensor is fixedly installed inside the aluminum alloy housing of the motor.
[0011] Preferably, a protective back cover is movably installed on the side of the protective housing away from the aluminum alloy housing of the motor, and an air intake filter is fixedly installed in the middle of the protective back cover.
[0012] Preferably, a plurality of first connecting screw holes are evenly provided on one side of the protective back cover, the first connecting screw holes penetrating the protective back cover, and a second connecting screw hole is provided on the side of the protective housing near the protective back cover, the second connecting screw hole corresponding to the first connecting screw hole, and a connecting bolt is threadedly connected to one side of the protective back cover, the connecting bolt being threadedly connected to the first connecting screw hole and the second connecting screw hole.
[0013] Preferably, a first connecting wire is fixedly installed on one side of the motor aluminum alloy housing, and the first connecting wire extends into the interior of the motor aluminum alloy housing; a second connecting wire is fixedly installed on one side of the protective housing, and the second connecting wire extends into the interior of the protective housing.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This high-stability automotive air conditioning damper actuator motor has a significantly increased heat dissipation area by fixing heat dissipation fins on the side of the motor body away from the motor shaft. When the motor body generates heat during operation, the heat is quickly conducted to the heat dissipation fins, which can quickly dissipate the heat to the surrounding air, effectively reducing the temperature of the motor body.
[0016] 2. This high-stability automotive air conditioning damper actuator motor drives the fan blades to rotate via a micro motor. The ventilation mesh on the side of the motor's aluminum alloy housing near the protective housing allows air to flow under the action of the fan blades. Cool air enters from the air intake filter in the middle of the protective rear cover, is accelerated by the fan blades, and then blows through the ventilation mesh onto the heat dissipation fins, quickly carrying away the heat emitted by the heat dissipation fins and further improving heat dissipation efficiency. Even in high-temperature environments, such as hot summers, this heat dissipation system can ensure stable operation of the motor and guarantee the normal operation of the automotive air conditioning damper actuator.
[0017] 3. This high-stability automotive air conditioning damper actuator motor features a temperature sensor that monitors the motor's internal temperature in real time. When the temperature sensor detects a temperature below the set suitable operating temperature limit (e.g., when the car is first started in cold winter, the motor temperature is low, the lubricating oil viscosity is high, affecting starting performance), the control system connected to the temperature sensor will activate the heating wire inside the protective housing. This heating wire connects to the motor's aluminum alloy casing and the electrical equipment inside the protective housing via the first and second connecting lines, and also connects to the external control system for easy signal transmission and control. The heat generated by the heating wire is transferred to the inside of the motor's aluminum alloy casing through air convection, raising the motor's temperature, reducing the lubricating oil viscosity, enabling the motor to start smoothly and operate normally, and improving the motor's working stability in low-temperature environments.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4This utility model provides a technical solution: a high-stability automotive air conditioning damper actuator motor, including a motor aluminum alloy housing 1, a motor body 2 fixedly installed inside one side of the motor aluminum alloy housing 1, a motor shaft 3 fixedly installed at the output end of the motor body 2, the motor shaft 3 extending to the outer end of the motor aluminum alloy housing 1, a protective shell 4 fixedly installed on the side of the motor aluminum alloy housing 1 away from the motor shaft 3, a heat dissipation fin 5 fixedly installed on the side of the motor body 2 away from the motor shaft 3, a support mounting rod 6 fixedly installed inside the protective shell 4, a micro motor 7 fixedly installed in the middle of the support mounting rod 6, a fan blade 8 fixedly installed at the output end of the micro motor 7, and a ventilation mesh 9 opened on the side of the motor aluminum alloy housing 1 near the protective shell 4. Heat is transferred to the heat dissipation fin 5 by heat conduction. The heat dissipation fin 5 has a large surface area, which can efficiently dissipate heat into the surrounding air, thereby cooling the motor body 2 and starting the micro motor 7 to rotate the fan blade 8.
[0025] A limiting rubber pad 10 is fixedly installed inside the aluminum alloy housing 1 of the motor. The limiting rubber pad 10 is fixedly connected to the outer end of the motor body 2. An exhaust mesh hole 11 is opened at the top of the aluminum alloy housing 1 of the motor. A heating wire 12 is fixedly installed inside the protective housing 4 on the side away from the micro motor 7. A temperature sensor 13 is fixedly installed inside the aluminum alloy housing 1 of the motor. A protective back cover 14 is movably installed on the side of the protective housing 4 away from the aluminum alloy housing 1 of the motor. An air intake filter 15 is fixedly installed in the middle of the protective back cover 14. Several first connecting screw holes 16 are evenly opened on one side of the protective back cover 14. The first connecting screw holes 16 penetrate the protective back cover 14. A second connecting screw hole 17 is opened on the side of the protective housing 4 near the protective back cover 14. The connecting screw hole 17 corresponds to the first connecting screw hole 16. A connecting bolt 18 is threadedly connected to one side of the protective back cover 14. The connecting bolt 18 is threadedly connected to the first connecting screw hole 16 and the second connecting screw hole 17. A first connecting line 19 is fixedly installed on one side of the motor aluminum alloy housing 1. The first connecting line 19 extends into the interior of the motor aluminum alloy housing 1. A second connecting line 20 is fixedly installed on one side of the protective housing 4. The second connecting line 20 extends into the interior of the protective housing 4. When the heating wire 12 is activated, it starts to work and generates a large amount of heat. This heat gradually increases the temperature of the motor body 2 through air convection. The limiting rubber pad 10 has good elasticity and buffering performance, which can effectively absorb and reduce vibration, and protect the motor body 2.
[0026] Working Principle: When needed, the motor is first connected to the electrical equipment inside the aluminum alloy housing 1 and the protective housing 4 via the first connecting line 19 and the second connecting line 20. It is also connected to the external control system for later signal transmission and control. During operation, heat is transferred to the heat dissipation fins 5 via thermal conduction. The heat dissipation fins 5 have a large surface area, efficiently dissipating heat into the surrounding air, thus cooling the motor body 2. The temperature sensor 13 monitors the temperature inside the aluminum alloy housing 1. When the temperature exceeds the preset value, the micro motor 7 (RS-380 model) is activated to rotate the fan blades 8. Under the action of the fan blades 8, air begins to flow. Cool air enters the protective housing 4 through the air intake filter 15 in the middle of the protective rear cover 14. Accelerated by the fan blades 8, the cool air is blown onto the heat dissipation fins 5 through the ventilation holes 9. The flowing cool air continuously carries away the heat dissipated by the heat dissipation fins 5. The exhaust air is then discharged through the exhaust mesh 11, forming a continuous cooling airflow circulation, further improving the heat dissipation efficiency and ensuring the operational stability of the motor body 2 under high temperature conditions or long-term operation. When the car is in a cold winter, the temperature of the motor body 2 is low when it is first started. At this time, the viscosity of the lubricating oil is high, which will seriously affect the starting performance of the motor. When the temperature sensor 13 detects that the temperature of the motor body 2 is lower than the preset suitable operating temperature lower limit, the starting heating wire 12 starts to work, generating a large amount of heat. This heat is transferred through air convection inside the protective shell 4 and the motor aluminum alloy shell 1, gradually increasing the temperature of the motor body 2. As the temperature rises, the viscosity of the lubricating oil decreases, enabling the motor to start smoothly and operate normally, improving the working stability of the motor in low temperature environments. The limiting rubber pad 10 has good elasticity and buffering performance, which can effectively absorb and weaken vibration, prevent the motor body 2 from shifting due to vibration or loosening of internal parts, and ensure the stable operation of the motor under complex road conditions.
