Description

Technical Field

[0001] This invention relates to the field of air conditioning damper actuation technology, and more particularly to an automotive air conditioning damper actuation mechanism. Background Technology

[0002] The automotive air conditioning damper actuator is a hydraulic drive system that integrates hydraulic components such as hydraulic pumps, hydraulic valves, hydraulic cylinders, and oil tanks into a single device. It is used to control the opening and closing and adjustment of the automotive air conditioning damper. Its working principle is to convert liquid pressure into fluid energy through the hydraulic pump, transmit it through hydraulic pipelines to the hydraulic valve for control, and then adjust the flow and pressure through the hydraulic valve and transmit it to the hydraulic cylinder to produce linear or rotary motion to drive the damper.

[0003] However, there is at least one problem with the relevant technology: the current assembly of automotive air conditioning damper actuators requires manual screw fixing and drilling, which is a cumbersome process and makes the automotive air conditioning damper actuators not very convenient. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automotive air conditioning damper actuator, the automotive air conditioning damper actuator including an oil tank and a hydraulic pump and a hydraulic valve that are snapped into the oil tank; A mounting assembly for installing a hydraulic pump is provided on one side of the oil tank; The mounting components include a mounting base, elastic elements, and limiting elements; the mounting base is fixed to one side of the oil tank adjacent to the hydraulic pump; The limiting component includes a connecting part and a limiting claw that are connected to each other. The connecting part is movably disposed in the matching groove of the fixed seat, and the limiting claw is assembled to the surface of the hydraulic pump to limit the movement of the hydraulic pump relative to the oil tank. The elastic element is connected between the fixed base and the connecting part, and is used to apply a force to the limiting claw to make the hydraulic pump press against the surface of the oil tank.

[0005] The technical advantage of the above-mentioned further solution is as follows: When workers need to assemble the integrated hydraulic pump and hydraulic valve, they first fill the oil tank with oil. Then, they lift the limiting component upwards, that is, away from the fixed base, to lengthen the elastic limiting component. Next, they place the hydraulic pump between the top of the oil tank and the bottom of the limiting component on the fixed base. Finally, they release the limiting component, and the elastic component's rebound causes the limiting claw to tightly engage the hydraulic pump. During this process, the sliding groove and the connecting part of the limiting component move in tandem, improving the stability of the limiting component during movement. Therefore, using the mounting assembly to install and fix the hydraulic pump replaces the traditional manual screw fixing, simplifying the assembly process and improving convenience.

[0006] In a preferred embodiment, the fixing base includes a first vertical plate, a second vertical plate, and a connecting plate connected between the first vertical plate and the second vertical plate; the first vertical plate and the second vertical plate are arranged opposite to each other, and the two are used to form a mating groove; The connecting plate is fixedly connected to the oil tank, and one end of the elastic element is connected to the top surface of the connecting plate, while the other end of the elastic element is connected to the bottom surface of the connecting part. When the limit chuck is assembled onto the surface of the hydraulic pump, the elastic element is in a stretched state.

[0007] In a preferred embodiment, the inner wall of the slide groove is provided with a plurality of stop teeth arranged at intervals along the first direction; an auxiliary stop block and a connecting spring are also provided between the connecting part and the inner wall. One end of the connecting spring is connected to a protruding protrusion on one side of the connecting part, and the auxiliary locking block is connected to the other end of the connecting spring for engaging with any of the multiple gear locking teeth. In this case, the first direction is parallel to the direction of the force.

[0008] In a preferred embodiment, the spacing between the first vertical plate and the second vertical plate gradually decreases from one end connected to the connecting plate to the other end.

[0009] In one preferred embodiment, an oil inlet pipe is fixedly connected through the top of the oil tank. One end of the oil inlet pipe is connected to the hydraulic pump and the hydraulic valve, and the other end of the oil inlet pipe is fixedly connected to the hydraulic cylinder. A return oil pipe is fixedly connected to one side of the hydraulic cylinder. A cooler is fixedly connected through one end of the return oil pipe, and the bottom of the cooler is fixedly connected to the top of the oil tank. The other end of the return oil pipe is connected through the top of the oil tank.

[0010] In one preferred embodiment, a pressing plate is snapped onto the top of the hydraulic valve, a pneumatic rod is fixedly connected to one side of the pressing plate, a flipping rod is connected through one end of the pneumatic rod, and the bottom of the pneumatic rod is fixedly connected to the top of the oil tank.

[0011] The technical effect of adopting the above-mentioned further solution is as follows: When it is necessary to install the hydraulic valve, the staff first manually flips the flipping rod, then the pneumatic rod automatically extends (the pneumatic rod can be referred to as the lifting mechanism at the bottom of the office chair), then the hydraulic valve is placed between the top of the oil tank and the bottom of the pressing plate, and finally the staff flips the flipping rod again, while pressing the pressing plate, the pneumatic rod will automatically move downward until it is locked onto the top of the hydraulic valve.

[0012] In one preferred embodiment, a suction cup is attached to one side of the hydraulic cylinder, a pneumatic cylinder is fixedly connected to one side of the suction cup, a piston is slidably connected to the inner wall of the pneumatic cylinder, a pull rod is fixedly connected to one side of the piston, one end of the pull rod is connected through to one end of the pneumatic cylinder, a vent hole is provided on the inner wall of the pneumatic cylinder, and one end of the pneumatic cylinder is fixedly connected to one side of the oil tank.

[0013] The technical effect of adopting the above-mentioned further solution is that when it is necessary to fix the hydraulic cylinder, the operator can manually push the pull rod until the piston reaches one end of the pneumatic cylinder, then attach the hydraulic cylinder to one side of the suction cup, and then pull the connecting rod in the opposite direction to make the pressure on the inner wall of the suction cup less than the external pressure through the vent hole, thereby causing the suction cup to be tightly attached to one side of the hydraulic cylinder. The operation steps are simple.

[0014] In a preferred embodiment, the end of the pneumatic cylinder near the suction cup is fixed to one side of the oil tank by welding, and the vent is opened on the inner wall of the end of the pneumatic cylinder away from the suction cup, and the diameter of the vent is smaller than the diameter of the piston.

[0015] In a preferred embodiment, the top of the oil tank is provided with an oil inlet, and a movable air pressure mechanism is provided on the oil inlet. The movable air pressure mechanism includes a hose, and the inner wall of the oil inlet is slidably connected to the hose. One end of the hose is fixedly connected to a receiving cylinder, and one end of the receiving cylinder is connected through a connecting rod. A circular plate is slidably connected to the inner wall of the receiving cylinder, and one side of the circular plate is fixedly connected to one end of the connecting rod.

[0016] The technical effect of adopting the above-mentioned further solution is as follows: When the operator removes the emulsion on the top of the engine oil, first insert the circular float and hose into the inner wall of the oil inlet. Then, the circular float makes one end of the hose float on the top of the engine oil. Then, the operator pulls the connecting rod through the circular plate to make the pressure change of the inner wall of the container automatically absorb the emulsion. Finally, the hose is pulled out and the connecting rod is pushed in the opposite direction to discharge the emulsion.

[0017] In one preferred embodiment, a circular float is fixedly connected to one end of the hose, and one side of the circular float is slidably connected to the inner wall of the oil inlet.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows: This invention allows workers to assemble automotive air conditioning damper actuators by first opening the limiting piece and then engaging the hydraulic pump. Next, workers adjust the length of the pneumatic rod by flipping the lever to facilitate engaging the hydraulic valve on top of the oil tank. Finally, workers attach the hydraulic cylinder to one side of the suction cup and pull the lever to complete the assembly. The operation is simple and suitable for assembling hydraulic components of different diameters, reducing the workload of workers. Furthermore, when it is necessary to remove emulsions from the hydraulic oil, the movable pneumatic mechanism allows for the insertion of a hose into the oil inlet, followed by pulling the connecting rod to absorb and discharge the emulsions, effectively improving the ease of use of the automotive air conditioning damper actuator.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-4The present invention provides a technical solution: an automotive air conditioning damper actuator, comprising an oil tank 1 and a hydraulic pump 4 and a hydraulic valve 5 engaged with the oil tank 1; a mounting assembly for mounting the hydraulic pump 4 is provided on one side of the oil tank 1; the mounting assembly includes a fixed base 14, an elastic element 13, and a limiting element 11; the fixed base 14 is fixed to the side of the oil tank 1 adjacent to the hydraulic pump 4; the limiting element 11 includes a connecting part 12 and a limiting claw connected to each other, the connecting part 12 is movably disposed in the mating groove 10 of the fixed base 14, and the limiting claw is assembled to the surface of the hydraulic pump 4 to restrict the movement of the hydraulic pump 4 relative to the oil tank 1; the elastic element 13 is connected between the fixed base 14 and the connecting part 12, and is used to apply a force to the limiting claw to cause the hydraulic pump 4 to abut against the surface of the oil tank 1.

[0023] Specifically, by using the limiting claws of the installation components in conjunction with the elastic element 13, the hydraulic pump 4 can be quickly assembled into the designated position in the oil tank 1. Furthermore, the force of the elastic element 13 ensures that the hydraulic pump 4 is tightly pressed against the surface of the oil tank 1, limiting its relative movement and guaranteeing installation stability. This eliminates the need for manual drilling and screw fixing, simplifying the assembly process: the hydraulic pump 4, hydraulic valve 5, and oil tank 1 are connected by a snap-fit ​​mechanism, eliminating the need for additional drilling and screwing, significantly reducing assembly steps, lowering manual labor intensity, and improving assembly efficiency.

[0024] Preferably, the fixed base 14 includes a first vertical plate 141, a second vertical plate 142, and a connecting plate connected between the first vertical plate 141 and the second vertical plate 142; the first vertical plate 141 and the second vertical plate 142 are arranged opposite to each other and are used to form a mating groove 10; the connecting plate is fixedly connected to the oil tank 1, and one end of the elastic member 13 is connected to the top surface of the connecting plate, and the other end of the elastic member 13 is connected to the bottom surface of the connecting part 12; wherein, when the limiting claw is assembled to the surface of the hydraulic pump 4, the elastic member 13 is in a stretched state.

[0025] Combination Figures 5-7 The inner wall of the sliding groove 10 is provided with a groove along the first direction 101 (see...). Figure 7 Multiple gear teeth 143 are arranged at intervals on the upper part; an auxiliary locking block 144 and a connecting spring 145 are also provided between the connecting part 12 and the inner wall; one end of the connecting spring 145 is connected to a protruding protrusion on one side of the connecting part 12, and the auxiliary locking block 144 is connected to the other end of the connecting spring 145 for cooperating with any of the multiple gear teeth 143; wherein, the first direction 101 is parallel to the direction of the force.

[0026] Specifically, by introducing the shift teeth 143 and the auxiliary locking block 144, the problem of the non-fixed position of the connecting part 12 on the mating slide 10 is solved, thereby improving installation stability and convenience. Specifically, the inner wall of the mating slide 10 is provided with multiple shift teeth 143 arranged at intervals along the first direction 101. By providing the shift teeth 143 on the inner wall of the mating slide 10, multiple fixed position points are provided, allowing different positions to be selected for locking according to actual needs, preventing the connecting part 12 from sliding freely on the mating slide 10. An auxiliary locking block 144 and a connecting spring 145 are also provided between the connecting part 12 and the inner wall. Adding the auxiliary locking block 144 and the connecting spring 145 between the connecting part 12 and the inner wall forms a movable locking mechanism, achieving dynamic position fixing. One end of the connecting spring 145 is connected to a protruding protrusion on one side of the connecting part 12. The connecting spring 145 is connected to the protrusion of the connecting part 12 to ensure that the auxiliary locking block 144 can move and reset elastically, which facilitates quick locking or releasing during installation. The auxiliary locking block 144 is connected to the other end of the connecting spring 145 and is used to cooperate with any of the multiple gear teeth 143. Under the action of the connecting spring 145, the auxiliary locking block 144 locks into any gear tooth 143 to achieve position locking and prevent the hydraulic pump 4 from displacing when subjected to force. The first direction 101 is parallel to the direction of the force, ensuring that the locking direction is consistent with the direction of the force applied by the elastic element 13, avoiding lateral sliding during the force process, and enhancing the stability and reliability of the overall structure.

[0027] Furthermore, by utilizing the added gear teeth 143 and auxiliary locking blocks 144, the stability of the applied force can be ensured during the process of the elastic element 13 applying force to the hydraulic pump 4.

[0028] Preferably, the distance between the first vertical plate 141 and the second vertical plate 142 gradually decreases from one end connected to the connecting plate to the other end. For example... Figure 1-4 As shown, an oil inlet pipe 3 is fixedly connected through the top of the oil tank 1. One end of the oil inlet pipe 3 is connected to the hydraulic pump 4 and the hydraulic valve 5, and the other end of the oil inlet pipe 3 is fixedly connected to the hydraulic cylinder 6. A return oil pipe 7 is fixedly connected to one side of the hydraulic cylinder 6. A cooler 8 is fixedly connected through one end of the return oil pipe 7. The bottom of the cooler 8 is fixedly connected to the top of the oil tank 1. The other end of the return oil pipe 7 is connected through the top of the oil tank 1.

[0029] In a specific example, when workers need to assemble the integrated hydraulic pump 4 and hydraulic valve 5, they first fill the oil tank 1 with oil through the inlet port 2. Then, they lift the limiting member 11 upwards, that is, away from the fixed base 14, to lengthen the elastic member 13. The hydraulic pump 4 is then placed between the top of the oil tank 1 and the bottom of the limiting member 11 on the fixed base 14. Finally, the limiting member 11 is released, and the elastic member 13 rebounds, causing the limiting claw of the limiting member 11 to tightly engage the hydraulic pump 4. During this process, the sliding groove 10 and the connecting part 12 of the limiting member 11 move together, improving the stability of the limiting member 11 during movement. Thus, using the mounting assembly to fix the hydraulic pump 4 replaces the traditional manual screw fixing, simplifying the assembly process and improving convenience.

[0030] like Figure 1-4 As shown, a pressing plate 17 is snapped onto the top of the hydraulic valve 5. A pneumatic rod 15 is fixedly connected to one side of the pressing plate 17. A flipping rod 16 is connected through one end of the pneumatic rod 15. The bottom of the pneumatic rod 15 is fixedly connected to the top of the oil tank 1. When the hydraulic valve 5 needs to be installed, the operator first manually flips the flipping rod 16. Then the pneumatic rod 15 automatically lengthens. The pneumatic rod 15 can be compared with the lifting mechanism at the bottom of the office chair. Then the hydraulic valve 5 is placed between the top of the oil tank 1 and the bottom of the pressing plate 17. Finally, the operator flips the flipping rod 16 again and presses the pressing plate 17. The pneumatic rod 15 will automatically move downward until it snaps onto the top of the hydraulic valve 5.

[0031] like Figure 1-4 As shown, a suction cup 21 is attached to one side of the hydraulic cylinder 6, and a pneumatic cylinder 27 is fixedly connected to one side of the suction cup 21. A piston 19 is slidably connected to the inner wall of the pneumatic cylinder 27, and a pull rod 18 is fixedly connected to one side of the piston 19. One end of the pull rod 18 is connected to one end of the pneumatic cylinder 27. A vent hole 20 is provided on the inner wall of the pneumatic cylinder 27. One end of the pneumatic cylinder 27 is fixedly connected to one side of the oil tank 1. When it is necessary to fix the hydraulic cylinder 6, the operator can manually push the pull rod 18 until the piston 19 reaches one end of the pneumatic cylinder 27, then press the hydraulic cylinder 6 against one side of the suction cup 21, and then pull the connecting rod 25 in the opposite direction. The pressure on the inner wall of the suction cup 21 is lower than the external pressure through the vent hole 20, which causes the suction cup 21 to be tightly attached to one side of the hydraulic cylinder 6. The operation steps are simple.

[0032] like Figure 1-4As shown, an oil inlet 2 is provided on the top of the oil tank 1. A movable air pressure mechanism is provided on the oil inlet 2. The movable air pressure mechanism includes a hose 22. The hose 22 is slidably connected to the inner wall of the oil inlet 2. A receiving cylinder 24 is fixedly connected to one end of the hose 22. A connecting rod 25 is connected through one end of the receiving cylinder 24. A circular plate 26 is slidably connected to the inner wall of the receiving cylinder 24. One side of the circular plate 26 is fixedly connected to one end of the connecting rod 25.

[0033] Furthermore, a circular float plate 23 is fixedly connected to one end of the hose 22. One side of the circular float plate 23 is slidably connected to the inner wall of the oil inlet 2. When the operator removes the emulsion on top of the hydraulic oil, the circular float plate 23 and the hose 22 are first inserted into the inner wall of the oil inlet 2. Then, the circular float plate 23 floats one end of the hose 22 on top of the hydraulic oil. Then, the operator pulls the connecting rod 25 through the circular plate 26 to lower the pressure inside the container 24 and automatically absorb the emulsion. Finally, the hose 22 is pulled out and the connecting rod 25 is pushed in the opposite direction to discharge the emulsion.

[0034] Preferably, the end of the pneumatic cylinder 27 near the suction cup 21 is fixed to one side of the oil tank 1 by welding, and the vent 20 is opened on the inner wall of the end of the pneumatic cylinder 27 away from the suction cup 21, and the diameter of the vent 20 is smaller than the diameter of the piston 19.

[0035] Furthermore, the circular float 23 is made of a lightweight elastic material, and the outer diameter of the circular float 23 is adapted to the inner diameter of the oil inlet 2. The connection between the hose 22 and the receiving cylinder 24 is sealed and fixed with sealant.

[0036] Working principle: When assembling the automotive air conditioning damper actuator, the worker first injects oil into the oil inlet 2. Then, the worker pulls the limiting member 11 upwards, and then places the hydraulic pump 4 between the top of the oil tank 1 and the bottom of the limiting member 11. Finally, the worker releases the limiting member 11 to fix the hydraulic pump 4. When installing the hydraulic valve 5, the worker first manually flips the flipping rod 16, then places the hydraulic valve 5 between the top of the oil tank 1 and the bottom of the pressing plate 17. Finally, the worker flips the flipping rod 16 again while pressing the pressing plate 17, causing the pneumatic rod 15 to move downwards. Simply tighten the hydraulic valve 5; when it is necessary to fix the hydraulic cylinder 6, the operator can manually push the pull rod 18 until the piston 19 reaches one end of the air cylinder 27, then attach the hydraulic cylinder 6 to one side of the suction cup 21, and then pull the connecting rod 25 in the opposite direction to complete the adsorption and fixation of the hydraulic cylinder 6; when the operator removes the emulsion on the top of the oil, first insert the circular float 23 and the hose 22 into the inner wall of the oil inlet 2, and then pull the connecting rod 25, which will cause the pressure change of the inner wall of the receiving cylinder 24 through the circular plate 26 to automatically absorb the emulsion, and after discharge, the purification of the hydraulic oil can be completed.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
