[0002] With the rapid development of the automotive industry, the rate of vehicle air conditioning installation in my country has increased year by year. Car air conditioners are crucial components in vehicles, frequently used and directly impacting driving and riding comfort. Consequently, these components are constantly being improved. The air outlet, as the terminal output component of a car air conditioner, regulates air volume and direction. Adjusting the air outlet can ensure optimal air circulation throughout the vehicle. Different air outlet structures require different durability tests, and only those that pass these tests and meet the required standards are considered qualified.

[0003] Current car air conditioner vents adjust air volume and direction by moving blades or adjusting the air angle by turning a knob. One of our customer's car air conditioner vents uses blades to control the airflow on and off, and flipping the blades up and down controls the airflow direction. This structure requires durability testing of the blades, which simultaneously move left and right and flip up and down. Due to the small size of this car air conditioner vent, the left and right and up and down flipping distances are limited, and manual testing is relatively difficult due to the need for repeated operations tens of thousands of times. Therefore, a durability testing device specifically designed for this type of car air conditioner vent structure is required. Summary of the Invention

DETAILED DESCRIPTION

[0023] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0024] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Please refer to Figure 1 and Figure 2 A vehicle air-conditioning outlet durability test device includes a fixing frame 1, a translation test cylinder 2, a translation test fixture 3, a flip test cylinder 4, a flip test fixture 5, and a control device 6. The air outlet 100 to be tested is fixedly installed on the fixing frame 1. A fixed rail 102 extending along the X direction is provided in the air outlet 100. An air outlet blade 101 is installed on the fixed rail 102. The air outlet blade 101 moves along the fixed rail 102 or flips up and down around the fixed rail 102; the translation test cylinder 2 is installed on the side of the air outlet 100 to be tested, the piston rod of the translation test cylinder 2 is extended and retracted along the X direction, the translation test fixture 3 is installed at the end of the piston rod of the translation test cylinder 2, and the translation test fixture 3 clamps Hold at both ends of the air outlet blade 101, the translation test cylinder 2 is connected to the control device 6, and the translation test cylinder 2 is controlled by the signal of the control device 6 to drive the translation test fixture 3 to clamp the air outlet blade 101 and move back and forth along the X direction; the flip test cylinder 4 is installed above or below the air outlet 100 to be tested, and the piston rod of the flip test cylinder 4 is extended and retracted perpendicular to the X direction, and the flip test fixture 5 is installed at the end of the piston rod of the flip test cylinder 4, and the flip test fixture 5 is clamped on the upper and lower sides of the air outlet blade 101, and the flip test cylinder 4 is connected to the control device 6, and the flip test cylinder 4 is controlled by the signal of the control device 6 to drive the flip test fixture 5 to clamp the air outlet blade 101 and flip it back and forth perpendicular to the X direction.

[0026] The vehicle air-conditioning outlet durability test device protected by the present invention mainly tests the blade-adjustable vehicle air-conditioning outlet 100, especially the outlet 100 whose air outlet blades 101 move left and right along the fixed rail 102 to control the air-conditioning outlet switch and flip up and down around the fixed rail 102 to control the air-conditioning outlet direction. During use, the air outlet 100 to be tested is mounted at a designated location on the fixed frame 1. The translation test fixture 3 and the flip test fixture 5 are clamped and fixed to the air outlet blade 101 to be tested. Instructions, such as the number of test repetitions and the distance the cylinders are to be extended or retracted each time, are input into the control device 6. This controls the translation test cylinder 2 and the flip test cylinder 4 to extend or retract according to the instructions, thereby driving the translation test fixture 3 and the flip test fixture 5 to hold the air outlet blade 101 in translation or reversal. After repeated testing thousands or even tens of thousands of times, the test is completed. The control device 6 controls the translation test cylinder 2 and the flip test cylinder 4 to stop, remove the translation test fixture 3 and the flip test fixture 5 from the air outlet blade 101 to be tested, and disassemble the air outlet 100 from the fixed frame 1. If the air outlet 100 can still be used normally after the endurance test, it is a qualified product. If the air outlet 100 cannot be used normally after the endurance test and does not meet the standards, it is a failed product.

[0027] In one embodiment, the translation test fixture 3 includes a left clamping arm 31, a right clamping arm 32, and a connecting arm 33. The left clamping arm 31 is clamped and fixed to one end of the outlet blade 101 along the X-direction, and the right clamping arm 32 is clamped and fixed to the other end of the outlet blade 101 along the X-direction. The bottom ends of the left and right clamping arms 31 and 32 are fixedly mounted on the connecting arm 33, which is connected and fixed to the end of the piston rod of the translation test cylinder 2. The left and right clamping arms 31 and 32 function to precisely translate the outlet blade 101 to be tested. They can be any structure known in the art that can clamp and limit the position of a flat structure such as the outlet blade 101.

[0028] Furthermore, the left clamping arm 31 and the right clamping arm 32 can be respectively clamped at the two ends of the air outlet blade 101, such as a spring clamp structure, which itself has a strong elastic clamping effect. Applying force to the spring clamp can make it open, and it will automatically close and clamp when no external force is applied. Under this structure, the air outlet blade 101 is clamped by the left clamping arm 31 and the right clamping arm 32 and moves back and forth left and right.

[0029] Furthermore, the left clamping arm 31 and the right clamping arm 32 can also be clamped on the left and right sides of the air outlet blade 101 along the X direction, that is, the distance between the left clamping arm 31 and the right clamping arm 32 is adjusted to be exactly the length of the air outlet blade 101. After installation, the air outlet blade 101 is limited and fixed to the left and right. When the left clamping arm 31 and the right clamping arm 32 move back and forth left and right as the translation test cylinder 2 extends and retracts, the air outlet blade 101 clamped in the middle also moves back and forth left and right.

[0030] In one embodiment, the left clamping arm 31 and the right clamping arm 32 can be detachably mounted on the connecting arm 33 , and the clamps can be easily replaced according to the air outlet blades 101 of different sizes and structures to achieve better clamping effects and more accurate test results.

[0031] In one embodiment, the translation test fixture 3 has a single clamping arm structure. This means that the right clamping arm 32 can be removed and the left clamping arm 31 can be installed solely on the connecting arm 33 to perform the reciprocating translation test of the air outlet 100. Alternatively, the right clamping arm 32 can be removed and the left clamping arm 31 can be installed solely on the connecting arm 33 to perform the reciprocating translation test of the air outlet 100. If the left and right clamping arms 31 and 32 are clamps that directly clamp onto the air outlet blades 101, such as spring clamps, a single clamp is required to drive the air outlet blades 101 to reciprocate along the X-direction. This simplifies the structure and can simulate the situation of moving the air outlet blades 101 left and right with one hand during daily operation.

[0032] In one embodiment, both the left clamping arm 31 and the right clamping arm 32 are movably mounted on the connecting arm 33. A slide rail can be provided on the connecting arm 33, and a cooperating sliding structure with a self-locking structure can be provided on the left clamping arm 31 and the right clamping arm 32. Alternatively, multiple mounting holes can be provided at different positions on the connecting arm 33, and the left clamping arm 31 and the right clamping arm 32 can be freely selected from the adjustment holes at different positions to be fixed with screws or other components. This structure allows the position and distance between the left clamping arm 31 and the right clamping arm 32 to be adjusted, and can adapt to different models of air outlets 100 and different testing requirements according to actual conditions. It can also simulate the situation in which an operator pinches different parts of the air outlet blades 101 and moves and adjusts them during daily use, thereby obtaining more accurate durability test results.

[0033] In one embodiment, the inner sides of the left and right clamping arms 31 and 32 are made of silicone where they meet the outlet blades 101 or the fixing rails 102. The use of soft silicone effectively simulates the human hand pinching the outlet blades 101 for adjustment, while also effectively preventing excessive clamping force from damaging the surface of the outlet blades 101 or even breaking them during testing.

[0034] In one embodiment, the flip test fixture 5 includes an upper clamp 51 and a lower clamp 52, and the upper clamp 51 and the lower clamp 52 are respectively located above and below the air outlet blade 101. When the flip test fixture 5 moves up and down driven by the flip test cylinder 4, the air outlet blade 101 is moved up and down around the fixed rail 102 by the upper clamp 51 and the lower clamp 52.

[0035] In a preferred embodiment, the upper and lower clamping pieces 51, 52 do not contact the outlet blade 101 simultaneously. When the flip test fixture 5 moves up and down, one of the upper and lower clamping pieces 51, 52 abuts against the outlet blade 101 and pushes the outlet blade 101 to flip, while a gap is left between the other and the outlet blade 101. Since the outlet blade 101 flips around the fixed rail 102 when flipping up and down, its edge trajectory is an arc, and the piston rod of the flip test cylinder 4 can only move straight up and down mechanically, and similarly, the flip test fixture 5 can only move straight up and down mechanically, the upper and lower clamping pieces 51, 52 cannot completely and tightly clamp the outlet blade 101, and a gap must be left to allow the edge of the outlet blade 101 to move in an arc shape when flipping.

[0036] In a preferred embodiment, the upper clip 51 and the lower clip 52 are both made of silicone and have a certain elasticity to prevent the air outlet blade 101 from being damaged or broken during the process of turning up and down.

[0037] In one embodiment, the flip test fixture 5 is detachably mounted on the end of the telescopic rod of the flip test cylinder 4. Different flip test fixtures 5 can be replaced according to actual conditions to adapt to the durability test of different models of air outlet blades 101, and can be replaced in time when a fault occurs.

[0038] In summary, the vehicle-mounted air-conditioning outlet durability testing device protected by the present invention has a simple structure, convenient installation, automated testing, strong applicability and accurate results.

[0039] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
