Description

Technical Field

[0001] This utility model relates to the field of material anti-aging testing technology, and in particular to an anti-aging testing device for automotive interior materials. Background Technology

[0002] The main automotive interior materials that require anti-aging tests include textiles and fiber materials, as well as artificial leather and leather materials, such as seat fabrics, headliner fabrics, carpets, and seat belts. All of these materials are at risk of aging under long-term exposure to sunlight.

[0003] Existing aging testing devices mainly employ xenon lamp aging or ultraviolet (UV) aging to simulate the aging effects of light on materials. However, automotive interior materials are also subject to dynamic friction aging in actual use. Existing devices, such as xenon lamp aging chambers, primarily focus on a single light exposure factor to accelerate aging simulation, while friction testing often uses separate equipment, such as the TABER abrasion tester and the Martindale tester. This separation of testing methods leads to a fragmented testing scenario, making it impossible to simulate the actual frictional damage that occurs simultaneously with light aging. For example, leather seats experience a decrease in hardness after prolonged exposure to sunlight, at which point dynamic friction accelerates aging, a process that existing devices cannot test.

[0004] To address this issue, we propose a testing device for the anti-aging properties of automotive interior materials. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-aging testing device for automotive interior materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-aging testing device for automotive interior materials includes a box body with an opening at the top and a closed cover. A frame is rotatably connected to the bottom of the cover, and the frame has multiple mounting surfaces evenly distributed around its perimeter.

[0008] The mounting surface is used to fix the material body, the bottom of the cover is provided with a friction mechanism for rubbing the material body, the cover is provided with a drive mechanism for driving the frame to rotate, and the bottom of the box is fixed with the xenon lamp body.

[0009] Preferably, each of the four corners of the top of the box is provided with a telescopically sliding light rod, which can move up and down, and the top of each of the four light rods is fixedly connected to the bottom of the cover.

[0010] Preferably, a xenon lamp body is fixed at the bottom of the housing. The xenon lamp body is arranged in a vertical column shape and is located in the middle of the frame. The frame covers the xenon lamp body on all sides.

[0011] Preferably, the mounting surface has a rectangular opening, and several round holes are provided on both the left and right sides of the rectangular opening, with the round holes on both sides being equidistant from top to bottom.

[0012] Preferably, the mounting surface is provided with buckles that can engage with the round holes. The four buckles can pass through the four corners of the material body and engage with the four round holes respectively, so as to fix the material body to the mounting surface.

[0013] Preferably, the buckle is equipped with an extension rod, one end of which can be engaged with a round hole, and the other end of which can be engaged with a buckle. The four buckles can penetrate the material body and be engaged with the four extension rods, and the four extension rods are respectively engaged with the four round holes. The four extension rods can increase the straight-line distance between the material body and the mounting surface.

[0014] Preferably, the friction mechanism includes a vertical frame, which is vertically arranged at the bottom of the cover. A friction block is fixed at the bottom of the vertical frame and is used to make frictional contact with the material body. A slider is fixed at the top of the vertical frame. A slide rail is provided at the bottom of the cover to match the sliding of the slider. An oblong hole is provided on the side of the slide rail. A screw is threadedly connected to the slider, and the screw passes through the oblong hole and is threadedly connected to the slider.

[0015] Preferably, the driving mechanism includes an annular rack, which is rotatably disposed inside the cover. The bottom of the frame is fixedly connected to the annular rack, and the annular rack is coaxially aligned with the top of the frame. A motor is fixed on the upper side of the cover, and a gear is coaxially fixed to the motor. The gear meshes with the annular rack. An annular groove is provided at the bottom of the housing, and the bottom of the frame can abut against and slide against the annular groove.

[0016] Preferably, a round rod is also provided on the mounting surface, with bolts threaded to both ends of the round rod. The bolts can pass through the round holes and be threadedly fixed to the round rod. The bolts can also pass through the material body and be threadedly connected to the round rod, thereby fixing the material body onto the mounting surface.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention combines light aging factors and dynamic friction aging factors by setting up a frame, a xenon lamp body, and a friction mechanism.

[0031] Example 1

[0032] Reference Figures 1-7 An anti-aging testing device for automotive interior materials includes a housing 1. The top of the housing 1 has an opening, and a cover 2 is provided to close the opening. A frame 3 is rotatably connected to the bottom of the cover 2. The frame 3 has multiple mounting surfaces 4, which are evenly distributed around the perimeter of the frame 3. Specifically, as shown... Figure 3 As shown. The mounting surface 4 is used to fix the material body 5, the bottom of the cover 2 is provided with a friction mechanism for rubbing the material body 5, and the cover 2 is provided with a drive mechanism for driving the frame 3 to rotate.

[0033] Those skilled in the art should know that when implementing the above technical solution, the material body 5 refers to the automotive interior material to be tested, such as textiles and fiber materials or artificial leather, leather materials, etc.

[0034] Those skilled in the art should know that, when implementing the above technical solution, the cabinet 1 is also equipped with an existing humidifier, heating device and heat dissipation device to achieve constant temperature and humidity conditions inside the cabinet 1, provide factors for temperature and humidity aging, and ensure the stability of the internal environment.

[0035] As a technical optimization of this utility model, each of the four corners of the top of the housing 1 is provided with a telescopic sliding rod 6. The rods 6 can move up and down, and the tops of the four rods 6 are fixedly connected to the bottom of the cover 2. The cover 2 can move upward and drive the frame 3 to move as a whole, ensuring that the frame 3 moves upward stably.

[0036] Those skilled in the art should know that when implementing the above technical solution, an electric telescopic rod can be installed on the side of the box 1. The electric telescopic rod can be used to control the lifting and lowering of the cover 2, so as to open and close the cover 2.

[0037] As a technical optimization of this utility model, a xenon lamp body 7 is fixed to the bottom of the housing 1. The xenon lamp body 7 is arranged in a vertical column shape and is located in the middle of the frame 3. The frame 3 covers the xenon lamp body 7 on all sides, as shown in the figure below. Figure 3As shown. After the material body 5 is mounted on the frame 3, the xenon lamp body 7 can radiate outward from the center of the frame 3 to achieve aging testing of the material body 5. The xenon lamp body 7 is used to provide illumination, which is the light aging factor of the test device. The light aging factor is a static environmental factor.

[0038] Those skilled in the art should know that when implementing the above technical solution, it is not limited to setting a xenon lamp body 7, but can also set an ultraviolet lamp, which can also provide light aging factors.

[0039] As a technical optimization of this utility model, the mounting surface 4 is provided with a rectangular opening, and several round holes 8 are provided on both the left and right sides of the rectangular opening. The several round holes 8 on both sides are arranged at equal intervals.

[0040] As a technical optimization of this utility model, a buckle 9 is provided on the mounting surface 4. The buckle 9 can engage with the round hole 8. The four buckles 9 can pass through the four corners of the material body 5 and engage with the four round holes 8 respectively, thus fixing the material body 5 onto the mounting surface 4. That is, through holes are pre-set at the four corners of the material body 5 to facilitate the passage of the buckles 9. See the specific reference. Figure 6 The four corners of the material body 5 are each passed through by a clip 9, and the four clips 9 are inserted into the four round holes 8 respectively, thus fixing the material body 5 to the mounting surface 4. The several round holes 8 on the left and right sides can accommodate the installation of multiple material bodies 5, and the material body 5 can also be flexibly adjusted in position.

[0041] As a technical optimization of this utility model, the buckle 9 is matched with an extension rod 10. One end of the extension rod 10 can be engaged with the round hole 8, and the other end of the extension rod 10 can be engaged with the buckle 9. The four buckles 9 can penetrate the material body 5 and be engaged with the four extension rods 10. The four extension rods 10 are respectively engaged with the four round holes 8. See the specific reference. Figure 7 The four extension rods 10 can increase the straight-line distance between the material body 5 and the mounting surface 4. The extension rods 10, together with the buckles 9, can fix the material body 5 and also change the distance between the material body 5 and the mounting surface 4, that is, change the distance between the material body 5 and the xenon lamp body 7. By changing the distance, the light intensity of the xenon lamp body 7 on the material body 5 can be changed.

[0042] One end of the extension rod 10 is provided with a cavity that matches the buckle 9. The cavity has two notches, and the buckle 9 can be inserted into the cavity and engage with the two notches.

[0043] Those skilled in the art should know that when implementing the above technical solution, the extension rod 10 can be provided with multiple length dimensions, and the selection of extension rods 10 with different length dimensions can change the distance between the material body 5 and the mounting surface 4.

[0044] As a technical optimization of this utility model, the friction mechanism includes a vertical frame 11, which is vertically arranged at the bottom of the cover 2. A friction block 12 is fixed at the bottom of the vertical frame 11, and the friction block 12 is used to rub against the material body 5. A slider is fixed at the top of the vertical frame 11. The bottom of the cover 2 is provided with a slide rail that matches the slider. The slide rail is provided with an oblong hole on its side. A screw is threadedly connected to the slider, and the screw passes through the oblong hole and is threadedly connected to the slider.

[0045] That is, the slider can slide along the slide rail, so that the vertical frame 11 can move. The screw plays the role of fixing the vertical frame 11. When the screw is rotated out, the vertical frame 11 and the slider can be removed from the slide rail. When the screw is rotated and tightened, the slider can be fixed by pressing the side of the slide rail, that is, the vertical frame 11 is fixed.

[0046] Those skilled in the art should know that when implementing the above technical solution, the vertical frame 11 can be set with multiple length dimensions. The selection of different lengths of the vertical frame 11 can change the position of the friction block 12 so that the position of the friction block 12 corresponds to the position of the material body 5. That is, after the position of the material body 5 is changed, the position of the friction block 12 can be adjusted to ensure that the friction block 12 can effectively correspond to the material body 5 to be tested.

[0047] As a technical optimization of this utility model, the driving mechanism includes an annular rack 13, which is rotatably disposed inside the cover 2. The bottom of the frame 3 is fixedly connected to the annular rack 13, and the annular rack 13 is coaxially aligned with the top of the frame 3. A motor 14 is fixedly mounted on the upper side of the cover 2, and a gear 15 is coaxially fixed to the motor 14, and the gear 15 is rotatably connected to the inside of the cover 2. The gear 15 meshes with the annular rack 13. The bottom of the housing 1 is provided with an annular groove, and the bottom of the frame 3 can abut against and slide against the annular groove. That is, multiple balls are rotatably mounted on the bottom of the frame 3, and the balls abut against the annular groove, allowing them to slide on the annular groove. The motor 14 is connected to an external power source via a power cord. Motor 14 controls gear 15 to rotate. Gear 15's rotation drives annular rack 13 to rotate, which in turn drives frame 3 to rotate. Frame 3's rotation then moves the material body 5 fixed to it. Each time material body 5 passes friction block 12, it rubs against friction block 12, achieving the effect of friction testing. Specifically... Figure 4 and Figure 5 As shown.

[0048] Those skilled in the art should know that, when implementing the above technical solutions, the above electrical equipment is controlled by a control module, that is, by a programmable PLC controller, and all of these are available on the market.

[0049] The working principle is as follows:

[0050] The material body 5 to be tested is installed on the mounting surface 4 of the frame 3. The frame 3 is then placed inside the housing 1. The number or position of the material bodies 5 can be adjusted as needed, with one material body 5 aligned with the friction block 12, ensuring frictional contact between the friction block 12 and the material body 5. The motor 14 is then activated, controlling the gear 15 to rotate. The rotation of the gear 15 drives the annular rack 13, which in turn rotates the frame 3, moving the material body 5 fixed to it. As the frame 3 rotates, the material body 5 revolves around the xenon lamp body 7, enabling light exposure testing. Each time the material body 5 passes the friction block 12, it rubs against it, achieving the effect of friction testing. This method combines light aging factors and dynamic friction aging factors, making the test scenario more closely resemble actual usage and effectively simulating the simultaneous frictional damage that occurs during light aging. Ultimately, this results in a more comprehensive and accurate overall anti-aging test.

[0051] The extension rod 10, in conjunction with the buckle 9, not only secures the material body 5 but also alters the distance between the material body 5 and the mounting surface 4, i.e., the distance between the material body 5 and the xenon lamp body 7. By changing the distance, the light intensity emitted by the xenon lamp body 7 onto the material body 5 can be altered. The material body 5, with its altered distance, can be offset from the friction block 12 to prevent it from hindering rotation during movement. Alternatively, the position of the friction block 12 can be adjusted to ensure contact between the material body 5 with its altered distance and the friction block 12.

[0052] Example 2

[0053] Reference Figure 8 The difference between this embodiment and Embodiment 1 is that:

[0054] A round rod 16 is also provided on the mounting surface 4. Both ends of the round rod 16 are threaded with bolts 17. The bolts 17 can pass through the round holes 8 and be threadedly fixed to the round rod 16. The bolts 17 can abut against the mounting surface 4 and can also pass through the material body 5 and be threaded to the round rod 16, thus fixing the material body 5 onto the mounting surface 4. Specifically, through holes are pre-set at the four corners of the material body 5 to facilitate the passage of the bolts 17. See [reference needed] for details. Figure 8 The four corners of the material body 5 are respectively passed through by bolts 17. The four bolts 17 are inserted into the four round holes 8 and threaded to the corresponding round rods 16, so that the material body 5 can be fixed to the mounting surface 4.

[0055] Those skilled in the art should know that when implementing the above technical solution, the round rod 16 can be provided with multiple length dimensions, and the selection of round rods 16 with different length dimensions can change the distance between the material body 5 and the mounting surface 4.

[0056] The working principle is as follows:

[0057] The round rod 16 and bolt 17 enable the installation of the material body 5, allowing the material body 5 to be installed in a flexible position on the mounting surface 4. The round rod 16 can be set with multiple lengths, and the selection of different lengths of the round rod 16 can change the distance between the material body 5 and the mounting surface 4, that is, change the distance between it and the xenon lamp body 7.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
