[0001] This utility model relates to the field of automotive parts technology, specifically to an air conditioning actuator. Background Technology

[0002] Air conditioning actuators are key components in air conditioning control systems, used to operate and control various functions within the system. Specifically, they receive instructions from the air conditioning controller and translate them into actual mechanical actions, such as adjusting the airflow mode, regulating the temperature, and controlling the opening and closing of the fresh air circulation.

[0003] Existing air conditioner actuators typically use drive mechanisms made of metal, which leads to significant wear between the drive mechanism and the gear mechanism, resulting in excessive noise. Furthermore, the gear mechanism occupies a large amount of space, making the installation of the entire device inconvenient. Therefore, we propose an air conditioner actuator. Utility Model Content

[0016] 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.

[0017] Please see Figures 1-3 This utility model provides a technical solution: an air conditioner actuator, including a mounting housing 1 and a slot 2. The top of the mounting housing 1 has multiple sets of protective housings 3. The bottom of the slot 2 is provided with a locking block 4 that engages with the protective housing 3. The mounting housing 1 is provided with a potentiometer 7 for providing position feedback. The mounting housing 1 is provided with a gear drive mechanism 6 for adjusting the position of the sliding contact inside the potentiometer 7. The mounting housing 1 is provided with a drive mechanism 5 for driving the gear drive mechanism 6 to rotate. The drive mechanism 5 includes a drive motor 8 and a drive worm gear 10. The drive motor 8 is fixedly installed inside the mounting housing 1, and the output end of the drive motor 8 is fixedly connected to the drive worm gear 10 made of plastic material.

[0018] The mounting housing 1 and the protective housing 3 are connected to each other via a slot 2 and a locking block 4, which facilitates the maintenance of the internal components of the mounting housing 1. The drive motor 8 in the drive mechanism 5 can drive the drive worm 10 to rotate. The drive worm 10 is made of plastic, which reduces friction between it and the gear drive mechanism 6 and reduces noise. The gear drive mechanism 6 can reduce the high speed and increase the output torque through a series of gears during transmission. The gear drive mechanism 6 can also reduce the installation space during drive operation.

[0019] Please see Figure 1 and Figure 2 The gear drive mechanism 6 includes a drive worm gear 11, a first gear disk 12, and a second gear disk 13. The drive worm gear 11, the first gear disk 12, and the second gear disk 13 are rotatably mounted inside the mounting housing 1. The drive worm gear 11 meshes with the drive worm 10. A third gear disk 14 is fixedly mounted on the top of the drive worm gear 11 and the bottom of the first gear disk 12. The third gear disk 14 on the top of the drive worm gear 11 meshes with the first gear disk 12, and the third gear disk 14 on the bottom of the first gear disk 12 meshes with the second gear disk 13. The rotation of the second gear disk 13 drives the sliding contact inside the potentiometer 7 to move. The shaft of the second gear disk 13 is inserted into the slot of the potentiometer body 15.

[0020] When the drive worm 10 rotates, it can drive the drive worm wheel 11 to rotate. The rotating drive worm wheel 11 can then drive the first gear wheel 12 to rotate via the third gear disk 14 at its top. The rotating first gear disk 12 can then drive the second gear disk 13 to rotate via the third gear disk 14 at its bottom. In this way, the rotating second gear disk 13 can move the sliding contact inside the potentiometer body 15, thereby causing the sliding contact to move and change along the resistance track. The drive worm wheel 11, the first gear disk 12, and the second gear disk 13, which are distributed vertically, can save installation space. Furthermore, the two sets of third gear disks 14 can still drive the first gear disk 12 and the second gear disk 13 to rotate.

[0021] Please see Figure 1 and Figure 2 The potentiometer 7 includes a potentiometer body 15, a first pin 16, a second pin 17, and a third pin 18. The potentiometer body 15 is disposed inside the mounting housing 1. The first pin 16, the second pin 17, and the third pin 18 are disposed on the potentiometer body 15. The first pin 16 and the third pin 18 are respectively connected to the resistance slide of the potentiometer body 15, and the second pin 17 is connected to the sliding contact of the potentiometer body 15.

[0022] When the second gear disk 13 rotates, it can drive the sliding contact to move along the sliding track. The movement of the sliding contact will cause the resistance value between the second pin 17 and the third pin 18 to change. During this period, the voltage between the second pin 17 and the third pin 18 will also change, while the voltage value between the first pin 16 and the third pin 18 remains unchanged. In this way, the position of the angle can be accurately determined and fed back by the voltage change between the second pin 17 and the third pin 18.

[0023] Please see Figure 1 and Figure 2 The outer casing 1 is fixedly mounted with a downwardly extending connecting bracket 21. One end of the connecting bracket 21 is fixedly connected to a mounting sleeve 22. The mounting sleeve 22 facilitates the installation of the entire device, while the downwardly extending connecting bracket 21 can raise the bottom of the outer casing 1 to prevent a large amount of heat from accumulating during operation.

[0024] Please see Figure 1 and Figure 2 The housing 1 has a positioning groove 9 inside. The end of the drive worm 10 away from the drive motor 8 is located inside the positioning groove 9. The fact that one end of the drive worm 10 can be located inside the positioning groove 9 can prevent the drive worm 10 from having a large displacement when the drive motor 8 drives the drive worm 10 to rotate.

[0025] Please see Figure 2The potentiometer body 15 is provided with a first terminal 19 and a second terminal 20 for powering the drive motor 8. The first terminal 19 and the second terminal 20 can be connected to the positive and negative poles of the drive motor 8, thereby driving the drive motor 8 to rotate.

[0026] In use, firstly, the drive motor 8 in the drive mechanism 5 drives the drive worm 10 to rotate. The drive worm 10 is made of plastic, which reduces friction between it and the gear drive mechanism 6, thus reducing noise. The gear drive mechanism 6, through a series of gear transmissions, can reduce high speeds and correspondingly increase output torque. Furthermore, the gear drive mechanism 6 reduces installation space during operation. When the drive worm 10 rotates, it drives the drive worm wheel 11 to rotate. The rotating drive worm wheel 11 then drives the first gear wheel 12 to rotate via its top third gear disc 14. The rotating first gear wheel 12, in turn, drives the second gear wheel 13 to rotate via its bottom third gear disc 14. This allows for the rotation of... The second gear disk 13 moves the sliding contact inside the potentiometer body 15, causing the sliding contact to move and change along the resistance track. In this way, the vertically distributed drive worm gear 11, first gear disk 12 and second gear disk 13 can save installation space. The two sets of third gear disks 14 can still drive the first gear disk 12 and second gear disk 13 to rotate. When the second gear disk 13 rotates, it can drive the sliding contact to move along the sliding track. The movement of the sliding contact will cause the resistance value between the second pin 17 and the third pin 18 to change. During this period, the voltage between the second pin 17 and the third pin 18 will also change, while the voltage value between the first pin 16 and the third pin 18 remains unchanged. In this way, the position of the angle can be accurately determined and fed back by the voltage change between the second pin 17 and the third pin 18.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
