Description

Technical Field

[0001] This utility model relates to the field of rubber strip testing technology, and in particular to an automotive rubber strip sealing testing device. Background Technology

[0002] With the continuous improvement of people's living standards, automobiles have become a widely used important means of transportation. Car doors are divided into outer door panels and inner door panels. The inner door panel has rubber strips around its perimeter, which contact the inner wall of the door frame. Rubber strips are installed at the bottom of the outer door panel, which contact the outer wall of the door frame. These rubber strips enhance the airtightness of the vehicle body, making the sound of the door closing more solid, effectively reducing wind noise, preventing dust and rainwater from entering the car, and enhancing waterproofing, dustproofing, and sound insulation, thus better meeting the needs of users.

[0003] The sealing performance of automotive door seals after installation directly affects their effectiveness and, consequently, the user experience. A common method for testing the sealing performance of automotive door seals involves installing the seal at the corresponding positions on the outer and inner door panels. Before closing the door, an A4 sheet of paper is placed between the two panels. After closing the door, the paper is pulled out, and the clamping force is observed to determine the seal performance. This method has a relatively large margin of error, relies too heavily on a single testing point, and has low accuracy, failing to meet the actual needs of standardized testing for automotive door seals. Utility Model Content

[0004] The purpose of this application is to provide an automotive rubber strip sealing test device to solve the problems mentioned in the background art, which is that the test method of judging the sealing performance of automotive rubber strips by pulling out A4 paper and observing the clamping force has large errors, the test points for automotive rubber strip sealing performance are too single, and the test accuracy is low, making it difficult to meet the actual needs of standardized testing of automotive rubber strips.

[0005] To achieve the above objectives, this application provides the following technical solution: an automotive rubber seal testing device, comprising a base, a simulation box fixed to the top of the base, a testing box fixedly inserted into the back of the simulation box, a simulated inner door panel block fixed to the open side of the testing box, a simulated outer door panel block hinged to the simulated inner door panel block, both the simulated inner door panel block and the simulated outer door panel block being located inside the simulation box, a blower simulation component and a water spray simulation component installed on the base, the blower simulation component blowing air at the connection between the simulated inner door panel block and the simulated outer door panel block, the water spray simulation component spraying water at the connection between the simulated inner door panel block and the simulated outer door panel block, a carrier block fixed to the top of the inner side of the testing box, several cloth strips fixed to the bottom of the carrier block, an air pump installed on the back of the testing box, an air supply pipe fixedly connected between the air outlet of the air pump and the testing box, an exhaust pipe fixedly connected to the left side of the testing box, and a first sealing cap threadedly connected to the left end of the exhaust pipe.

[0006] Furthermore, the air pump's air inlet is fixedly connected to an air inlet pipe, and an electric heating wire is installed inside the air inlet pipe.

[0007] Furthermore, the simulation box has two hinged doors on its front side, and handles are fixed on the doors.

[0008] Furthermore, a drain pipe is fixedly connected to the back of the simulation box, and a drain valve is installed on the drain pipe.

[0009] Furthermore, the blower simulation component includes a fan, which is mounted on a base. The fan's outlet is fixedly connected to an air supply pipe, and the other end of the air supply pipe is fixedly connected to a first ring pipe. Several air outlet pipes are fixedly connected to the first ring pipe, and the first ring pipe is located inside the simulation chamber.

[0010] Furthermore, the water spray simulation component includes a water storage tank, which is mounted on a base. A water pump is installed on the top of the water storage tank. The water pump's inlet is fixedly connected to an inlet pipe that extends into the interior of the water storage tank. The water pump's outlet is fixedly connected to a delivery pipe, and the other end of the delivery pipe is fixedly connected to a second ring pipe. Several nozzles are installed on the second ring pipe, which is located inside the simulation tank. A water injection pipe is fixedly connected to the top of the water storage tank, and a second sealing cap is threaded onto the top of the water injection pipe.

[0011] Furthermore, two reinforcing plates are fixed inside the simulation box, and the reinforcing plates are fixedly sleeved on the outside of the first ring tube and the second ring tube.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, a blower simulation component and a water spray simulation component are used to simulate natural weather. The sealing performance of the rubber strips installed on the simulated blocks of the inner and outer door panels is tested by wind and water. By checking whether the cloth strip in the test box swings and whether water accumulates inside the test box, the sealing performance of the automotive rubber strips can be accurately and effectively determined, thus meeting the standardized testing requirements for automotive rubber strips.

[0014] 2. In this utility model, an air pump is used to draw in outside air along the air intake pipe. The heating wire in the air intake pipe heats the incoming air.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example: Reference Figure 1-6 The illustrated automotive rubber seal testing device includes a base 1, a simulation box 2 fixed to the top of the base 1, a testing box 3 fixedly inserted to the back of the simulation box 2, a simulated inner door panel 4 fixed to the open side of the testing box 3, a simulated outer door panel 5 hinged to the simulated inner door panel 4, both the simulated inner door panel 4 and the simulated outer door panel 5 being located inside the simulation box 2, a blower simulation component and a water spray simulation component mounted on the base 1, the blower simulation component blowing air at the connection between the simulated inner door panel 4 and the simulated outer door panel 5, and the water spray simulation component spraying water at the connection between the simulated inner door panel 4 and the simulated outer door panel 5, a carrier block 6 fixed to the top of the inner side of the testing box 3, and a carrier block 6 fixed to the bottom. The test box 3 has multiple cloth strips 7. An air pump 8 is installed on the back of the test box 3. The air inlet of the air pump 8 is fixedly connected to an air inlet pipe 9. An electric heating wire is installed inside the air inlet pipe 9. An air supply pipe 10 is fixedly connected between the air outlet of the air pump 8 and the test box 3. An exhaust pipe 11 is fixedly connected to the left side of the test box 3. A first sealing cover 12 is threadedly connected to the left end of the exhaust pipe 11. Two doors 13 are hinged to the front of the simulation box 2. A handle 14 is fixed on the door 13. The simulation box 2, together with the two doors 13, can block the water sprayed by the water spray simulation component inside the simulation box 2. A drain pipe is fixedly connected to the back of the simulation box 2. A drain valve is installed on the drain pipe. When the drain valve is opened, the water in the simulation box 2 can be discharged along the drain pipe.

[0025] By using a blower simulation component and a water spray simulation component to simulate natural weather, the sealing performance of the rubber strips installed on the inner door panel simulation block 4 and the outer door panel simulation block 5 is tested by wind and water. By checking whether the cloth strip 7 in the test box 3 is swinging and observing whether water accumulates inside the test box 3, the sealing performance of the car rubber strips can be accurately and effectively determined.

[0026] Air pump 8 draws in outside air along the intake pipe 9. The heating wire in the intake pipe 9 heats the incoming air. Air pump 8 sends the hot air into the test chamber 3 along the air delivery pipe 10. The first sealing cover 12 is unscrewed, and the air in the test chamber 3 can be discharged along the exhaust pipe 11. In this way, the inside of the test chamber 3 can be dried to ensure that the inside of the test chamber 3 is dry before use, so as to accurately test the sealing performance of the automotive rubber strips.

[0027] The blower simulation component includes a blower 15, which is mounted on a base 1. The outlet of the blower 15 is fixedly connected to an air supply pipe 16, and the other end of the air supply pipe 16 is fixedly connected to a first ring pipe 17. Multiple outlet pipes 18 are fixedly connected to the first ring pipe 17, and the first ring pipe 17 is located inside the simulation box 2.

[0028] The blower 15 blows air into the first ring pipe 17, so that the air is directed out along the multiple air outlet pipes 18 on the first ring pipe 17 and blown in all directions to the connection between the inner door panel simulation block 4 and the outer door panel simulation block 5, so as to facilitate the testing of the sealing performance of the automotive rubber strip.

[0029] The water spray simulation component includes a water storage tank 19, which is mounted on a base 1. A water pump 20 is mounted on the top of the water storage tank 19. The inlet of the water pump 20 is fixedly connected to an inlet pipe that extends into the interior of the water storage tank 19. The outlet of the water pump 20 is fixedly connected to a water delivery pipe 21. The other end of the water delivery pipe 21 is fixedly connected to a second ring pipe 22. Multiple nozzles 23 are mounted on the second ring pipe 22, which is located inside the simulation box 2. A water injection pipe 25 is fixedly connected to the top of the water storage tank 19. A second sealing cap 26 is threadedly connected to the top of the water injection pipe 25. Two reinforcing plates 24 are fixedly mounted inside the simulation box 2. The reinforcing plates 24 are fixedly sleeved on the outside of the first ring pipe 17 and the second ring pipe 22 to enhance the stability of the first ring pipe 17 and the second ring pipe 22 in the simulation box 2.

[0030] The water pump 20 can be used to send water from the water tank 19 to the second ring pipe 22. The water is sprayed out along the multiple nozzles 23 on the second ring pipe 22 and directed at the connection between the inner door panel simulation block 4 and the outer door panel simulation block 5, so as to facilitate the testing of the sealing performance of the car rubber strip. By unscrewing the second sealing cap 26, water can be injected into the interior of the water tank 19 along the water injection pipe 25.

[0031] Working principle of this utility model:

[0032] After opening the two doors 13, pull the outer door panel simulation block 5 and the inner door panel simulation block 4 to separate them. Install the test strips on the inner door panel simulation block 4 and the outer door panel simulation block 5 respectively. After the inner door panel simulation block 4 and the test box 3 are glued together, apply sealant to the connection point to ensure a complete seal. Close the outer door panel simulation block 5 to close the inner door panel simulation block 4 and the outer door panel simulation block 5. Unscrew the first sealing cover 12 and turn on the air pump 8 and the heating wire. The air pump 8 draws in outside air along the air inlet pipe 9 and the heating wire heats the air. The hot air is sent into the test box 3 by the air pump 8 along the air delivery pipe 10. The hot air dries the inside of the test box 3. The moisture can be discharged along the exhaust pipe 11. After the inside of the test box 3 is completely dried, turn off the air pump 8 and screw the first sealing cover 12 back onto the exhaust pipe 11. After the cloth strip 7 hangs vertically and remains still, start the subsequent testing work.

[0033] Close both doors 13, turn on the fan 15 to blow air into the first ring pipe 17, and the air is discharged along the multiple air outlet pipes 18 on the first ring pipe 17, blowing towards the connection between the inner door panel simulation block 4 and the outer door panel simulation block 5. Observe whether the fabric strip 7 in the test box 3 is swaying. If the sealing of the rubber strip between the inner door panel simulation block 4 and the outer door panel simulation block 5 is not good, the air will enter along the gap, causing the fabric strip 7 to sway. If the fabric strip 7 does not sway, operate the water pump 20 to send the water in the water tank 19 to the second ring pipe 22. The water is sprayed out along the multiple nozzles 23 on the second ring pipe 22, shooting towards the connection between the inner door panel simulation block 4 and the outer door panel simulation block 5. Observe whether water droplets appear inside the test box 3. If they appear, it indicates that the sealing of the rubber strip between the inner door panel simulation block 4 and the outer door panel simulation block 5 is not good. If no water droplets appear, it indicates that the sealing of the rubber strip between the inner door panel simulation block 4 and the outer door panel simulation block 5 is qualified.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
