Description

Technical Field

[0001] The present invention relates to the technical field of automobile air-conditioning accessories, in particular to a durability testing system for automobile air-conditioning panel buttons. Background Art

[0002] With the rapid development of the automotive industry, the quality and reliability requirements of automobiles are becoming increasingly higher. As an important part of the car interior, the panel buttons of the car air conditioner are used frequently, which directly affects the user experience and the overall quality of the car. To ensure that the car air conditioner panel buttons can work stably and reliably throughout the service life of the vehicle, they need to be subjected to durability testing to simulate various operating conditions during actual use and verify the performance and life of the buttons.

[0003] Previous key durability tests may have used manual testing methods, which made it difficult to ensure test consistency and accuracy. The force, frequency, and method of operation may vary, and it is impossible to accurately simulate the operating habits of real users, resulting in deviations in test results. In addition, the test cannot be continued for a long time, which obviously cannot meet the requirements for some situations that require a large number of cyclic tests.

[0004] In conjunction with the above, it should be noted that: For example, Chinese patent application number 202121915010X discloses a durability test device for automobile air-conditioning controller buttons, which uses a crank slider mechanism to ensure precise limit of button pressing stroke and avoid damage to the buttons caused by test bench overload. All mechanisms of the device meet high and low temperature environment requirements and can realize high and low temperature environment testing; However, during actual use, the air-conditioning panel buttons follow the vehicle usage environment and need to be used in different environments. The mechanical pressing durability test expressed solely by the above content does not conform to the actual situation, so it is impossible to effectively detect the precise conditions related to the durability of the air-conditioning panel. At the same time, the test results of the mechanical pressing conditions of the air-conditioning panel buttons cannot be effectively and quickly fed back, resulting in a lag in the test results. Summary of the Invention

[0005] The purpose of the present invention is to provide a car air-conditioning panel key durability testing system to solve the problem raised.

A return pipe located below the filter is provided on the inner wall of the bottom of the aggregate inclined frame. The return pipe is connected to the storage box and the pump. After the dust-laden air is extracted and filtered by the filter, the intercepted test dust is centrally extracted through the return pipe and transported to the storage box for recycling.

The hot air blower and the compressor are used to generate high-temperature and low-temperature hot air, and are connected to the spray slot 602 through a pipe fitting.

[0024] During the test, according to the simulation needs of the test environment, the hot air blower and the compressor are gradually started, and the hot air and cold air are guided into the sealed test cavity through the pipe fittings to simulate the hot and cold environments of the air-conditioning panel button assembly. Then, the storage box extracts part of the test dust through the pump and guides it into the spray slot 602 through the pipe fitting. The spray slot 602 guides the test dust to be sprayed on the surface of the air-conditioning panel button assembly. The booster fan 504 partially connected to the internal circulation of the test box 503 is started. The booster fan 504 of this part extracts the air containing the test dust from the sealed test cavity, filters it through the filter element set on the inner wall of the test box 503 by the booster fan 504, and compresses the extracted air and guides it into the spray slot 602, thereby accelerating the airflow inside the sealed test cavity, thereby entraining the test dust to erode the air-conditioning panel button assembly, and quickly constructing a simulation of the use condition of the air-conditioning panel button assembly in the harsh environment of the car with impurities deposited.

[0025] Then cooperate with the detection device 6 to perform a pressing durability test on it, which is used to detect the durability and life span of the air-conditioning panel button assembly after simulating long-term use inside the actual vehicle and use in different environmental conditions. It should be noted that: an electric gate valve close to the filter element and facing the aggregate inclined rack 301 is provided at the bottom of the detection box 503, which is used to adjust the opening according to the detection needs, so as to realize the centralized discharge of the air containing test dust inside the sealed test cavity, and use the booster fan 504 to continuously circulate the air inside the sealed test cavity, so that the test dust on the surface of the air-conditioning panel button assembly after the test is cleaned.

[0026] A sliding cavity is provided inside the conveying guide frame 4, and a sliding kit 401 is provided through the sliding cavity to be clamped with the limit test fixture 402.

Several groups of high-pressure nozzles 202 are provided on the surface of the telescopic jet cover 201. An arc-shaped cylinder connected to the telescopic jet cover 201 is provided inside the cleaning cover frame 2, and the high-pressure nozzles 202 are respectively directed towards the limit test fixture 402 and the detection device 6, and the high-pressure nozzles 202 are connected to the booster fan 504 through pipe fittings.

[0029] After the detection box and the limit test fixture 402 are separated by a certain distance, the arc cylinder drives the telescopic jet hood 201 to unfold, and the telescopic jet hood 201 extends along the arc trajectory close to between the detection box 503 and the limit test fixture 402. Part of the booster fan 504 guides the air pressure through the pipe to be injected into the high-pressure nozzle 202. The high-pressure nozzle 202 guides the airflow to flush the surface of the detection box 503 and the limit test fixture 402, so that the test dust retained on their surface is cleaned.

[0030] During the cleaning of the high-pressure nozzle 202, the rotating motor 404 drives the limit test fixture 402 to rotate along the surface of the sliding kit 401, prompting the limit test fixture 402 to carry the air-conditioning panel button assembly to rotate and move, changing the orientation of the air-conditioning panel button assembly, and combining its own weight and the detection of the air flow inside the middle cavity 101 in this state to accelerate the cleaning of the test dust on the surface of the air-conditioning panel button assembly.

Internal adjustment cylinder 2 507 connected to the detection device 6 is provided on the inner wall of the internal adjustment cylinder 1 506. An expansion sealing groove 505 is provided on the inner wall of the end of the detection box 503 facing the limit test fixture 402.

[0033] The expansion sealing groove 505 is connected to the booster fan 504 through a pipe fitting, so that when the detection box 503 and the limit test fixture 402 are connected, the expansion airbag in the expansion sealing groove 505 is used to inflate and clamp the sealing frame 403, thereby promoting the construction of a sealed test cavity between the detection box 503 and the limit test fixture 402, thereby facilitating the real environment simulation of the durability test of the air-conditioning panel buttons in dust, cold and hot environments.

[0034] The horizontal axis cylinder 5 drives the vertical axis cylinder 501 to move axially, and the vertical axis cylinder 501 drives the detection box to move horizontally close to the limit test fixture 402.

A fine-tuning cylinder connected to the movable pressure block 601 is provided inside the detection device 6. The fine-tuning cylinder is used to drive the movable pressure block 601 to extend, and the movable pressure block 601 extends to contact the button on the surface of the air-conditioning panel button assembly, thereby realizing mechanical testing of the buttons on the surface of the air-conditioning panel button assembly.

[0036] The detection device 6 is provided with several groups of movable pressure blocks 601 on the surface of one end facing the limit test fixture 402, and spray slots 602 are provided above the several groups of movable pressure blocks 601. A return pipe 303 located below the filter 302 is provided on the inner wall of the bottom of the aggregate inclined frame 301. The return pipe 303 is connected to the storage box and the pump. After the dust-laden air is extracted and filtered by the filter 302, the intercepted test dust is centrally extracted through the return pipe 303 and transported to the storage box for recycling.

[0037] The circulation mechanism 3 filters the air in the detection cavity 101 through the filter 302. The filter 302 is connected to a part of the booster fan 504 through a pipeline, so that the test dust intercepted by the filter 302 falls and accumulates on the surface of the return pipe 303. The return pipe 303 is regularly extracted by the pump and the accumulated test dust is extracted into the storage box. The side of the pump can be equipped with spare fans and other components. The components can be added and set according to actual needs, but are not limited to this.

It should be noted that i is a natural number greater than zero, such as 、 ,…, , Similarly; The touch data analysis module calculates the average pressing force of n press data, where n is a natural number greater than zero.

When the qualified rate of the trigger of the received communication signal is insufficient, it generates a code such as "C-02" and sends the test result to the control panel in the form of text "Button number: A001, insufficient qualified rate of trigger, test time: 20xx.xx.xx". The control panel starts the flashing light and voice broadcast at the same time.

[0046] After receiving the feedback data group, the tactile data analysis module marks and groups each group of data within the feedback data group, calculates the average value of the response time data and the effective trigger rate of the press trigger status data, and retrieves the preset response time threshold and trigger qualification rate threshold from the detection center platform for comparison and analysis with the marked grouped data. If the response time exceeds the limit or the effective trigger rate is lower than the threshold, a communication signal containing the communication performance abnormality type is generated and sent to the supervision marking module.
