Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts testing technology, specifically to an aging resistance testing device for automotive interior parts. Background Technology

[0002] Automotive interior components, such as dashboards, passenger side panels, headliners, seats, seat belts, and door panels, are subject to various factors including light, heat, and humidity due to prolonged exposure to the vehicle's interior environment, leading to material aging. This aging not only affects the appearance of automotive interior components, such as surface cracking, powdering, deformation, spots, whitening, and blistering, but also alters their physical, mechanical, and electrical properties, ultimately impacting the overall performance and safety of the vehicle. Therefore, conducting aging resistance testing on automotive interior components is particularly important.

[0003] A Chinese patent document with authorization announcement number CN221926070U discloses an aging resistance testing device for automotive interior parts, including a cooling fan, a cold air duct, and a fixing mechanism. A second cylinder drives a second connecting seat, causing the first and second testing covers to open around a measuring support shaft, facilitating the insertion or removal of the automotive interior parts to be tested. Furthermore, after testing, the automotive interior parts are cooled by sending cold air through the cold air duct into an annular hole located on the tested automotive interior part. The cold air is then blown onto the tested automotive interior parts between the second and first testing covers through air holes in the annular hole. This device can test automotive interior parts not only under low-temperature and high-temperature light conditions but also under high-temperature and high-light conditions.

[0004] While the aforementioned patent documents can perform aging resistance tests on automotive interior parts under both low and high temperature conditions, the fixed annular holes and heating tubes may prevent some areas of the interior parts from meeting the necessary testing conditions, thus adversely affecting the overall testing results and reducing the comprehensiveness and accuracy of the test results. Utility Model Content

[0005] To address the aforementioned issues, an aging resistance testing device for automotive interior parts is provided. This device solves the technical problem that some automotive interior parts cannot withstand the necessary testing conditions by using an intermittent rotating component to drive the intermittent rotation of the testing frame.

[0006] To address the problems in the existing technology, this utility model provides an aging resistance testing device for automotive interior parts, including a testing box. A box cover is provided on one side of the testing box. A testing frame is rotatably mounted inside the testing box via a rotating shaft. One end of the testing box is provided with an intermittent rotating component for driving the testing frame to rotate intermittently. The top of the testing frame is provided with a clamping component for clamping and fixing the automotive interior parts. Testing heating tubes are provided on both the box cover and the inner wall of the testing box. A cooling fan is also provided on one side of the testing box, and a cold air duct is provided on the top of the cooling fan, with one end of the cold air duct connected to the testing box.

[0007] Preferably, the intermittent rotating component includes a driven wheel, a rotating rod, and an extension frame; one end of the rotating shaft extends outward through one side of the detection box, the driven wheel is disposed at the extended end of the rotating shaft, and a receiving groove is formed on the driven wheel; the rotating rod is disposed at one end of the detection box, located on one side of the driven wheel, one end of the rotating rod is provided with a driving wheel, one side of the driving wheel is provided with a pin, and a first gear is also sleeved on the rotating rod; the extension frame is disposed on one side of the rotating rod, one end of the extension frame is provided with a first motor, the output end of the first motor is provided with a second gear, and the second gear meshes with the first gear.

[0008] Preferably, the clamping component includes a gantry frame; two gantry frames are provided and slidably mounted on the detection frame, and a threaded rod is threadedly connected to the top of the gantry frame, with a knob at one end of the threaded rod and a pressure plate at the other end of the threaded rod.

[0009] Preferably, an extension block is provided on the inner side of the gantry frame, and a bolt is threaded onto the extension block. A screw hole is also provided on the top of the inspection frame for the bolt to be threaded onto.

[0010] Preferably, a connecting column is slidably disposed on one side of the threaded rod on the gantry frame, one end of the connecting column is connected to the top of the pressure plate, and a limiting ring is disposed on the other end of the connecting column.

[0011] Preferably, the bottom of the pressure plate is provided with an anti-slip layer, which is made of rubber.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. By starting the first motor, the output of the first motor drives the second gear to rotate. Since the second gear meshes with the first gear, the first gear also rotates. As the first gear rotates, the rotating rod also rotates. At this time, the pin on the driving wheel will periodically enter and leave the receiving groove on the driven wheel. When the pin enters the receiving groove, the pin will push the driven wheel to rotate at a certain angle; when the pin leaves the receiving groove, the driven wheel will stop rotating until the pin enters the receiving groove again, thus realizing the intermittent rotation of the driven wheel. Since the driven wheel is connected to the rotating shaft, the intermittent rotation of the driven wheel will drive the rotating shaft and the testing frame to rotate together, so that the automotive interior parts can be evenly subjected to the testing conditions during the testing process, thereby improving the comprehensiveness and accuracy of the aging resistance testing of automotive interior parts.

[0014] 2. By adjusting the positions of the two gantry frames on the testing frame according to the size and shape of the automotive interior parts to be tested, and by sliding the gantry frames to adapt to the width and length of the automotive interior parts, the knob is manually rotated to move the threaded rod on the gantry frame. The movement of the threaded rod drives the pressure plate to move until the pressure plate contacts the surface of the automotive interior parts. After the pressure plate contacts the surface of the automotive interior parts, the knob is rotated again to move the threaded rod further downward, so that the pressure plate applies a certain pressure to the automotive interior parts, thereby firmly clamping the automotive interior parts on the testing frame, ensuring the stability and safety of the automotive interior parts during the testing process.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1 to 7 As shown, this utility model provides an aging resistance testing device for automotive interior parts, including a testing box 1, a box cover 2 on one side of the testing box 1, a testing frame 3 rotatably mounted inside the testing box 1 via a rotating shaft, an intermittent rotating component 4 for driving the intermittent rotation of the testing frame 3 at one end of the testing box 1, a clamping component 5 for clamping and fixing the automotive interior parts at the top of the testing frame 3, a testing heating tube 6 on both the box cover 2 and the inner wall of the testing box 1, a cooling fan 7 on one side of the testing box 1, a cold air pipe 8 on the top of the cooling fan 7, and one end of the cold air pipe 8 connected to the testing box 1.

[0025] First, open the lid 2 and place the automotive interior parts to be tested on the testing frame 3, securing them with the clamping component 5 to ensure stability and safety during testing. Then, close the lid 2 to ensure the testing chamber 1 is airtight. Activate the heating element 6 to raise the temperature inside the testing chamber 1 to the predetermined high-temperature range. Simultaneously, the intermittent rotating component 4 drives the testing frame 3 to rotate intermittently, ensuring that different parts of the automotive interior parts receive uniform high-temperature testing conditions. After completing the high-temperature testing, turn off the heating element 6 and activate the cooling fan 7. The cold air generated by the cooling fan 7 is delivered into the testing chamber 1 through the cold air duct 8, lowering the temperature inside the testing chamber 1 to the predetermined low-temperature range. This ensures that different parts of the automotive interior parts receive uniform low-temperature testing conditions, guaranteeing uniform heating and cooling during testing and improving the comprehensiveness and accuracy of the testing.

[0026] See Figures 1 to 5As shown, the intermittent rotating component 4 includes a driven wheel 41, a rotating rod 42, and an extension frame 46; one end of the rotating shaft extends outward through one side of the detection box 1, the driven wheel 41 is located at the extended end of the rotating shaft, and a receiving groove is provided on the driven wheel 41; one end of the rotating rod 42 is located at one side of the driven wheel 41, one end of the rotating rod 42 is provided with a driving wheel 43, one side of the driving wheel 43 is provided with a pin 44, and a first gear 45 is also sleeved on the rotating rod 42; the extension frame 46 is located at one side of the rotating rod 42, one end of the extension frame 46 is provided with a first motor 47, the output end of the first motor 47 is provided with a second gear 48, and the second gear 48 meshes with the first gear 45.

[0027] By activating the first motor 47, the output of the first motor 47 drives the second gear 48 to rotate. Since the second gear 48 meshes with the first gear 45, the first gear 45 also rotates. As the first gear 45 rotates, the rotating rod 42 also rotates. At this time, the pin 44 on the driving wheel 43 periodically enters and leaves the receiving groove on the driven wheel 41. When the pin 44 enters the receiving groove, it pushes the driven wheel 41 to rotate at a certain angle; when the pin 44 leaves the receiving groove, the driven wheel 41 stops rotating until the pin 44 re-enters the receiving groove, thus achieving intermittent rotation of the driven wheel 41. Since the driven wheel 41 is connected to the rotating shaft, the intermittent rotation of the driven wheel 41 drives the rotating shaft and the testing frame 3 to rotate together, so that the automotive interior parts can be uniformly subjected to testing conditions during the testing process, thereby improving the comprehensiveness and accuracy of the aging resistance testing of automotive interior parts.

[0028] See Figure 6 and Figure 7 As shown, the clamping component 5 includes a gantry frame 51; there are two gantry frames 51 and they are slidably mounted on the inspection frame 3. The top of the gantry frame 51 is threadedly connected to a threaded rod 52. One end of the threaded rod 52 is provided with a knob 53, and the other end of the threaded rod 52 is provided with a pressure plate 54.

[0029] The positions of the two gantry frames 51 on the testing frame 3 are adjusted according to the size and shape of the automotive interior part to be tested. The gantry frames 51 are slidable to adapt to the width and length of the automotive interior part. Next, the knob 53 is manually rotated to move the threaded rod 52 on the gantry frame 51. The movement of the threaded rod 52 drives the pressure plate 54 to move until it contacts the surface of the automotive interior part. Once the pressure plate 54 is in contact with the surface of the automotive interior part, the knob 53 is continued to be rotated, causing the threaded rod 52 to move further downwards. This allows the pressure plate 54 to apply pressure to the automotive interior part, thus firmly clamping it onto the testing frame 3, ensuring the stability and safety of the automotive interior part during testing.

[0030] See Figure 7As shown, an extension block 57 is provided on the inner side of the gantry frame 51, and a bolt 58 is threadedly connected to the extension block 57. A screw hole is also provided on the top of the inspection frame 3 for the bolt 58 to be threadedly connected.

[0031] By sliding the gantry 51 to the appropriate position on the inspection frame 3, ensure that the distance between the two gantry 51 matches the width of the automotive interior part to be tested. Next, pass the bolt 58 through the threaded hole on the extension block 57 and rotate the bolt 58 to engage with the threaded hole on the inspection frame 3 until the bolt 58 is fully screwed into the threaded hole. The gantry 51 will be firmly fixed on the inspection frame 3, thereby improving the stability of the automotive interior part after clamping.

[0032] See Figure 6 As shown, a connecting column 55 is slidably arranged on one side of the threaded rod 52 on the gantry frame 51. One end of the connecting column 55 is connected to the top of the pressure plate 54, and a limiting ring 56 is provided at the other end of the connecting column 55.

[0033] When the movement of the threaded rod 52 causes the pressure plate 54 to move, the pressure plate 54 will drive the connecting column 55 to move, thereby improving the stability of the movement of the pressure plate 54.

[0034] See Figure 6 As shown, the bottom of the pressure plate 54 is provided with an anti-slip layer, which is made of rubber.

[0035] The anti-slip layer made of rubber at the bottom of the pressure plate 54 increases the friction between the pressure plate 54 and the automotive interior parts, preventing the interior parts from sliding or shifting due to vibration or external force during the testing process.

[0036] First, open the chamber cover 2 and place the automotive interior trim to be tested on the testing frame 3. Adjust the positions of the two gantry frames 51 on the testing frame 3 according to the size and shape of the automotive interior trim. Slide the gantry frames 51 to adapt to the width and length of the automotive interior trim. Next, manually rotate the knob 53 to move the threaded rod 52 on the gantry frame 51. The movement of the threaded rod 52 drives the pressure plate 54 to move until the pressure plate 54 contacts the surface of the automotive interior trim. After the pressure plate 54 contacts the surface of the automotive interior trim, continue rotating the knob 53 to move the threaded rod 52 further downward, so that the pressure plate 54 applies a certain pressure to the automotive interior trim, thus firmly clamping the automotive interior trim onto the testing frame 3, ensuring the stability and safety of the automotive interior trim during the testing process. Then, close the chamber cover 2 to ensure the sealing of the testing chamber 1. Activate the testing heating tube 6 to raise the temperature inside the testing chamber 1 to the predetermined high temperature range. Simultaneously, start the first motor 47, whose output drives the second gear 48 to rotate. Since the second gear 48 meshes with the first gear 45, the first gear 45 will also rotate. As the first gear 45 rotates, the rotating rod 42 will also rotate. At this time, the pin 44 on the driving wheel 43 will periodically enter and leave the receiving groove on the driven wheel 41. When the pin 44 enters the receiving groove, the pin 44 will push the driven wheel 41 to rotate at a certain angle; when the pin 44 leaves the receiving groove, the driven wheel 41 will stop rotating until the pin 44 enters the receiving groove again, thus realizing the intermittent rotation of the driven wheel 41. Since the driven wheel 41 is connected to the rotating shaft, the intermittent rotation of the driven wheel 41 will drive the rotating shaft and the testing frame 3 to rotate together, so that the automotive interior parts can be uniformly subjected to testing conditions during the testing process. After the high-temperature test is completed, the testing heating tube 6 is turned off and the cooling fan 7 is started. The cold air generated by the refrigeration fan 7 is sent into the test chamber 1 through the cold air duct 8, which lowers the temperature inside the test chamber 1 to the predetermined low temperature range. This allows different parts of the automotive interior parts to be uniformly subjected to low temperature testing conditions, thereby ensuring uniform heating and cooling of the automotive interior parts during the testing process and improving the comprehensiveness and accuracy of the testing.
