Description

Technical Field

[0001] This utility model relates to the technical field of automotive automatic air conditioning water valve actuators, and in particular to a noise reduction and buffer connection component for automotive automatic air conditioning water valve actuators. Background Technology

[0002] The water valve actuator receives signals from the air conditioning control system and automatically adjusts the opening and closing of the water valve to achieve precise control of the vehicle's interior temperature. With the continuous advancement of automotive technology, the intelligence and automation of automotive air conditioning systems are increasing. As a key control component in the air conditioning system, the automotive automatic air conditioning water valve actuator is responsible for regulating the flow of coolant to achieve precise control of the vehicle's interior temperature. However, existing water valve actuators often generate a certain amount of noise during operation, especially at the moment the valve opens and closes. This noise not only affects the comfort of the vehicle but may also negatively impact the driver's driving experience. Therefore, a noise reduction and buffer connection component for automotive automatic air conditioning water valve actuators is needed.

[0003] In existing technologies, many water valve actuators use a rigid connection method. When the actuator moves, especially during the rapid opening and closing of the valve, the lack of a buffer mechanism leads to direct impact and friction between the actuator and the valve. This direct physical contact generates severe vibration and impact, resulting in significant noise and affecting the driving experience. Moreover, prolonged vibration and impact can accelerate the wear of mechanical components of the actuator and valve, reducing the reliability and service life of the system, thereby increasing maintenance costs and replacement frequency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a noise reduction and buffer connection component for an automatic air conditioning water valve actuator in automobiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A noise reduction and buffer connection assembly for an automotive automatic air conditioning water valve actuator includes a mounting base. The mounting base has a mounting groove on its top. Two connecting seats are symmetrically arranged on the inner sidewall of the mounting groove, and both connecting seats are hollow structures. Each of the two symmetrical outer sidewalls of the two connecting seats has a first through groove. Each of the two symmetrical outer sidewalls of the mounting base has a first snap-fit ​​mechanism for respectively snapping the two connecting seats. The top of the mounting base has a fixing mechanism for fixing the two connecting seats. The same actuator body is housed inside the two connecting seats. The inlet and outlet ends of the actuator body each have built-in connecting pipes, and the ends of the two connecting pipes that are far apart from each other pass through the outside of the two first through grooves. The sidewalls of the two connecting pipes are provided with buffer mechanisms for buffering the actuator body. Noise reduction mechanisms are provided inside the two actuator bodies. During use, the noise reduction mechanisms effectively isolate and absorb the noise emitted by the actuator body during operation, thereby improving the driving and riding experience. The buffer mechanism design effectively absorbs the impact force of the actuator body during operation, reducing vibration, improving system stability and reliability, and reducing maintenance costs and replacement frequency.

[0007] As a further embodiment of this utility model, the noise reduction mechanism includes two U-shaped sound insulation plates, which are respectively fixed to the inner sidewalls of two connecting seats. The two outer sidewalls of the two U-shaped sound insulation plates are symmetrically provided with second through slots, and the four second through slots correspond one-to-one with the four first through slots. The cavities of the two connecting seats are filled with sound insulation cotton. The noise emitted by the actuator body is isolated by the two connecting seats and the two sound insulation cotton. At the same time, the two U-shaped sound insulation plates can absorb and process the noise emitted by the actuator body, further reducing noise and improving the driving experience.

[0008] As a further embodiment of this utility model, the buffer mechanism includes an annular plate, which is sleeved on the outer wall of one of the connecting pipes. A limit ring is sleeved on the outer wall of one of the connecting pipes. The same damper is provided between the two connecting seats, and the output end of the damper is fixed to the annular plate. A damping spring is sleeved on the outer wall of the damper. A base plate is fixed to the bottom of the damper. Two locking blocks are symmetrically fixed to the bottom of each of the two connecting seats, and all four locking blocks are adapted to the base plate. The output end of the damper is fixed to the annular plate, which can effectively absorb the impact force of the actuator body during the movement. The damping spring sleeved on the outer wall of the damper provides an additional buffering effect, thereby reducing vibration, improving the reliability and service life of the system, and thus reducing maintenance costs and replacement frequency.

[0009] As a further embodiment of this utility model, the snap-fit ​​mechanism includes two sleeves. Two sleeves are symmetrically arranged through the outer wall of one end of the mounting base. Circular sliders are slidably connected to the inner walls of both sleeves. A circular locking block is fixed to one end of each of the two circular sliders, and one end of each circular locking block penetrates the outer wall of one end of the sleeve. A connecting rod is fixed to the other end of each of the two circular sliders, and one end of each connecting rod penetrates the outer wall of the other end of the two sleeves. A spring is fitted onto the side wall of each connecting rod. Two springs are provided on the outer wall of one of the connecting bases. The four connecting rods are designed with four circular holes, each of which is fitted with a circular locking block. By pulling the four connecting rods, the four circular sliders move along the inner walls of the four sleeves until the four circular locking blocks retract into the four sleeves. At this point, all four springs are compressed. Insert one end of each connecting seat into the mounting groove. The two connecting seats are now aligned. Release the four connecting rods. Under the reaction force of the four compressed springs, the four circular sliders move in the opposite direction until one end of each circular locking block is pushed into the four circular holes, thus completing the initial fixing of the two connecting seats.

[0010] As a further embodiment of this utility model, the fixing mechanism includes a U-shaped plate. The same U-shaped plate is sleeved on the outer walls of the two connecting seats. L-shaped plates are rotatably connected to the four corners of the outer walls of the U-shaped plate. Circular grooves are opened in the top of the four L-shaped plates. Circular extrusion plates are slidably connected to the inner walls of the four circular grooves. Threaded rods are rotatably connected to the bottom of the four circular extrusion plates, and the four threaded rods pass through the bottom of the four L-shaped plates respectively. Threaded holes are opened in the bottom of the four L-shaped plates, and the four threaded holes are respectively adapted to the four threaded rods. U-shaped plates are fixed to the outer walls of the two connecting seats, and the two U-shaped plates are located below the U-shaped plate. By rotating the four L-shaped plates, the inner tops of the four L-shaped plates contact the bottoms of the two U-shaped plates respectively. By rotating the four threaded rods and engaging the four threaded holes, the four circular extrusion plates are made to tightly contact the bottoms of the two U-shaped plates respectively, thus completing the fixing of the two connecting seats. This allows the actuator body to be located inside the space formed by the two connecting seats.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, the actuator body is installed inside the space formed by the two connecting seats. With the help of the noise reduction mechanism, it can effectively isolate and absorb the noise emitted by the actuator body when it is working, thereby improving the driving and riding experience.

[0013] 2. The design of the buffer mechanism can effectively absorb the impact force of the actuator body during operation, reduce vibration, improve the stability and reliability of the system, and reduce maintenance costs and replacement frequency. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1 - Figure 10 A noise reduction and buffer connection assembly for an automatic air conditioning water valve actuator in an automobile includes a mounting base 1. The top of the mounting base 1 has a mounting groove 6. Two connecting seats 2 are symmetrically arranged on the inner wall of the mounting groove 6, and both connecting seats 2 are hollow structures. The two outer walls of the two connecting seats 2 each have a first through groove 16. The two outer walls of the mounting base 1 each have a first snap-fit ​​mechanism for snapping the two connecting seats 2 into place. The top of the mounting base 1 has a fixing mechanism for securing the two connecting seats 2. The two connecting seats 2 each house the same actuator body 14. The inlet and outlet ends of the actuator body 14 each have a built-in connecting pipe 15. The two connecting pipes 15 are separated by one end and pass through the outside of the two first through slots 16 respectively. The side walls of the two connecting pipes 15 are provided with buffering mechanisms for buffering the actuator body 14. The two actuator bodies 14 are provided with noise reduction mechanisms. During use, the noise reduction mechanism can effectively isolate and absorb the noise emitted by the actuator body 14 during operation, thereby improving the driving and riding experience. The design of the buffering mechanism can effectively absorb the impact force of the actuator body 14 during operation, reduce vibration, improve the stability and reliability of the system, and reduce maintenance costs and replacement frequency.

[0027] In this embodiment, the noise reduction mechanism includes two U-shaped sound insulation plates 13, which are fixed to the inner walls of the two connecting seats 2 respectively. The two outer walls of the two U-shaped sound insulation plates 13 are symmetrically provided with second through slots, and the four second through slots correspond one-to-one with the four first through slots 16. The cavities of the two connecting seats 2 are filled with sound insulation cotton 17. The noise emitted by the actuator body 14 is isolated by the two connecting seats 2 and the two sound insulation cotton 17. At the same time, the two U-shaped sound insulation plates 13 can absorb and process the noise emitted by the actuator body 14, further reducing noise and improving the driving experience.

[0028] In this embodiment, the buffer mechanism includes an annular plate 19, which is sleeved on the outer wall of one of the connecting pipes 15. A limit ring 18 is sleeved on the outer wall of one of the connecting pipes 15. The same damper 21 is provided between the two connecting seats 2, and the output end of the damper 21 is fixed to the annular plate 19. A damping spring 22 is sleeved on the outer wall of the damper 21. A base plate 20 is fixed to the bottom of the damper 21. Two locking blocks 23 are symmetrically fixed to the bottom of each of the two connecting seats 2, and all four locking blocks 23 are adapted to the base plate 20. The output end of the damper 21 is fixed to the annular plate 19, which can effectively absorb the impact force of the actuator body 14 during the movement. The damping spring 22 sleeved on the outer wall of the damper 21 provides an additional buffering effect, thereby reducing vibration, improving the reliability and service life of the system, and thus reducing maintenance costs and replacement frequency.

[0029] In this embodiment, the snap-fit ​​mechanism includes two sleeves 7. Two sleeves 7 are symmetrically arranged through the outer wall of one end of the mounting base 1. Circular sliders 8 are slidably connected to the inner walls of both sleeves 7. Circular locking blocks 9 are fixed to one end of each of the two circular sliders 8, and one end of each circular locking block 9 passes through the outer wall of one end of the sleeve 7. Connecting rods 10 are fixed to the other ends of both circular sliders 8, and one end of each connecting rod 10 passes through the outer wall of the other end of the two sleeves 7. Springs 11 are sleeved on the side walls of both connecting rods 10. Two circular holes 12 are opened on the outer wall of one of the connecting bases 2. Do not mate with the two circular locking blocks 9. By pulling the four connecting rods 10, the four circular sliders 8 move along the inner walls of the four sleeves 7 respectively until the four circular locking blocks 9 are retracted into the four sleeves 7. At this time, the four springs 11 are all in a compressed state. Insert one end of the two connecting seats 2 into the mounting groove 6. At this time, the two connecting seats 2 are in an overlapping state. Then, release the four connecting rods 10. Under the reaction of the four compressed springs 11, push the four circular sliders 8 to move in the opposite direction until one end of the four circular locking blocks 9 is pushed into the four circular holes 12, thus completing the initial fixing of the two connecting seats 2.

[0030] In this embodiment, the fixing mechanism includes a U-shaped plate 3. The outer walls of the two connecting seats 2 are fitted with the same U-shaped plate 3. L-shaped plates 24 are rotatably connected to the four corners of the outer walls of the U-shaped plate 3. Circular grooves 25 are formed in the top of each of the four L-shaped plates 24. Circular pressing plates 26 are slidably connected to the inner walls of each of the four circular grooves 25. Threaded rods 27 are rotatably connected to the bottom of each of the four circular pressing plates 26, and the four threaded rods 27 pass through the bottom of each of the four L-shaped plates 24. Threaded holes are formed in the bottom of each of the four L-shaped plates 24. The four threaded rods 27 are adapted to each other. The outer walls of the two connecting seats 2 are fixed with U-shaped plates 4, and the two U-shaped plates 4 are located below the U-shaped plate 3. The four L-shaped plates 24 are rotated so that the inner top of the four L-shaped plates 24 contacts the bottom of the two U-shaped plates 4 respectively. Then, the four threaded rods 27 are rotated to cooperate with the four threaded holes so that the four circular extrusion plates 26 are in close contact with the bottom of the two U-shaped plates 4 respectively. This completes the fixing of the two connecting seats 2, so that the actuator body 14 is located inside the space formed by the two connecting seats 2.

[0031] Working principle: During the use of this device, when installing the actuator body 14, two connecting pipes 15 are pre-fixed to the inlet and outlet ends of the actuator body 14, respectively. Two annular plates 19 are then fitted onto the outer walls of the two connecting pipes 15 until they are in contact with the two limiting rings 18. The two ends of the connecting pipes 15, which are far apart from each other, are then connected to the external system via flexible hoses. At this point, by pulling the four connecting rods 10, the four circular sliders 8 move along the inner walls of the four sleeves 7 until the four circular locking blocks 9 retract into the four sleeves 7. With all four springs 11 compressed, one end of each of the two connecting seats 2 is inserted into the mounting slot 6, at which point the two connecting seats 2 are aligned. Then, the four connecting rods 10 are released, and under the reaction force of the four compressed springs 11, the four circular sliders 8 are pushed to move in the opposite direction until one end of each of the four circular locking blocks 9 is pushed into the four circular holes 12, thus completing the initial fixing of the two connecting seats 2. At this point, the actuator body 14 is located inside the two connecting seats 2, and the eight locking blocks 23 are located at the four corners of the top of the two base plates 20, thus completing the fixing of the two base plates 20 and preventing the annular plate from being fixed. If the damper 19 and damper 21 shift during subsequent use, affecting operation, the output end of damper 21 is fixed to the annular plate 19, effectively absorbing the impact force of the actuator body 14 during movement. The damping spring 22 sleeved on the outer wall of damper 21 provides additional buffering effect, thereby reducing vibration, improving system reliability and service life, and reducing maintenance costs and replacement frequency. At this time, the loop plate 3 is sleeved on the outer wall of the two connecting seats 2 until the bottom of the loop plate 3 contacts the top of the two U-shaped plates 4. Then, the four L-shaped plates 24 are rotated so that the four L-shaped plates... The inner top of 24 contacts the bottom of the two U-shaped plates 4 respectively. By rotating the four threaded rods 27 and engaging the four threaded holes, the four circular extrusion plates 26 are made to make tight contact with the bottom of the two U-shaped plates 4 respectively, thus completing the fixing of the two connecting seats 2. This allows the actuator body 14 to be located inside the space formed by the two connecting seats 2. The noise emitted by the actuator body 14 is isolated by the two connecting seats 2 and the two sound insulation cotton 17. At the same time, the two U-shaped sound insulation plates 13 can absorb and process the noise emitted by the actuator body 14, further reducing noise and improving the driving experience.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
