[0002] Automotive door interior panels are typically made of multiple layers of different materials bonded together. After the first batch is completed, the automotive door interior panels need to be tested for harmful substances.

[0003] A search of Chinese patent CN208984609U reveals a testing fixture for automotive door interior panels. The fixture includes a box for holding the panels, an opening on the right side, and evenly distributed insertion holes on the inner left wall of the box. Rods for supporting the automotive door interior panels are inserted through these holes. An openable cover is located on the right side of the box, and a fan for increasing airflow is installed on the inner side of the cover. Support legs are welded to the outer wall of the fan, and screws are fitted between the support legs and the cover. A cover plate is screwed to the end of the fan near the cover, and a sleeve is machined at the axial position of the cover plate. Filter cotton for capturing harmful substances is installed inside the sleeve. This product can be used with existing testing equipment to achieve high-precision inspection.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] While the aforementioned technologies can effectively fix and seal the door interior panels, and the data obtained under sealed conditions is accurate and valid, during use, the air is in fixed contact with the interior panels, and some parts of the interior panels cannot make good contact with the air, which leads to deviations in the test results. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a testing device for detecting automotive interior panels, which achieves the effect of rotating the interior panel while air is being introduced, thereby increasing the accuracy of the test.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a testing device for detecting automotive interior panels, including a box and a cover plate. The cover plate is movably installed inside the box. Two mounting seats are symmetrically fixedly installed on the inner wall of the box. Mounting arms are movably installed on both mounting seats. A clamping mechanism is provided on the mounting arms. An air inlet is opened on one side wall of the box. An air guide hood is fixedly installed on the inner wall of the box corresponding to the position of the air inlet. An air detector is provided on the other side wall of the box. A drive mechanism is provided inside the box.

[0008] The drive mechanism includes:

[0009] The drive motor is embedded inside one of the mounting brackets, and the output end of the drive motor is fixedly connected to a mounting arm.

[0010] A bevel gear ring is fixedly fitted onto a mounting arm that is connected to the drive motor.

[0011] The transmission rod, fan blade, and transmission bevel gear are arranged laterally on one side of the bevel gear ring. The fan blade is movably installed inside the air inlet, and the transmission bevel gear is fixedly installed on the other end of the transmission rod.

[0012] In some embodiments, one end of the transmission rod is fixedly connected to the fan blade, and the transmission bevel gear meshes with the bevel gear ring.

[0013] In some embodiments, a mounting bearing is embedded in the mounting base, and a mounting arm is fixedly mounted on the inner ring of the mounting bearing, and the mounting arm is movably mounted on the mounting base via the mounting bearing.

[0014] In some embodiments, the clamping mechanism includes a movable arm, a clamping block, springs, and a mounting spring. The movable arm is movably mounted on the mounting arm and extends through one side wall of the mounting arm. The clamping block is fixedly mounted on the movable arm. There are multiple springs, which are disposed on the upper and lower sides inside the clamping block. The mounting spring is disposed inside the mounting arm and connected to the movable arm.

[0015] In some embodiments, one end of the spring is fixedly connected to the clamping block.

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an improved testing device for inspecting automotive interior panels. The technical solution of this utility model is as follows:

[0028] like Figures 1 to 4 As shown, a testing device for inspecting automotive interior panels includes a housing 1 and a cover 2. The housing 1 is a hollow rectangular structure. The cover 2 is movably installed inside the housing 1. Two mounting seats 3 are symmetrically fixedly installed on the inner wall of the housing 1. The mounting seats 3 are cylindrical structures, and mounting arms 4 are movably installed on both mounting seats 3. The mounting arms 4 are hollow cylindrical structures and are equipped with clamping mechanisms. An air inlet 9 is opened on one side wall of the housing 1. The air inlet 9 is a circular hole, and the inner wall of the housing 1 corresponds to the position of the air inlet 9. A fixed air guide 10 is installed. The air guide 10 is a hollow frustum structure. An air detector 11 is installed on the other side wall of the box 1. The interior panel is clamped by a clamping mechanism. Then, outside air is introduced into the box 1 through the air inlet 9. After the air is detected by the air detector 11, it leaves the box 1. During the movement, the air will come into contact with the interior panel. The air detector 11 can detect whether there is residual formaldehyde on the interior panel by detecting the air data. A drive mechanism is installed inside the box 1.

[0029] The drive mechanism includes a drive motor 12, a bevel gear ring 13, a transmission rod 14, a fan blade 15, and a transmission bevel gear 16. The drive motor 12 is embedded inside one of the mounting bases 3, and its output end is fixedly connected to a mounting arm 4. The bevel gear ring 13 is an annular structure and is fixedly sleeved on the mounting arm 4 connected to the drive motor 12. The transmission rod 14 is a cylindrical structure and is laterally positioned on one side of the bevel gear ring 13. The fan blade 15 is movably installed inside the air inlet 9, with one end of the transmission rod 14 fixedly connected to the fan blade 15. The transmission bevel gear 16 is fixedly installed on the other end of the transmission rod 14, and the transmission bevel gear 16 is positioned between the transmission bevel gear 16 and the bevel gear ring 13. The meshing transmission, through the setting of the drive mechanism, after the interior panel is clamped by the clamping mechanism, the drive motor 12 can be started. The drive motor 12 drives the mounting arm 4 to rotate, which in turn drives the interior panel to rotate. The rotation of the interior panel increases the contact area with the air, increasing the test accuracy. At the same time, it drives the bevel ring 13 to rotate. The bevel ring 13 drives the transmission rod 14 to rotate through the transmission bevel 16. The transmission rod 14 then drives the fan blade 15 to rotate inside the air inlet 9, thereby generating suction inside the air inlet 9, and thus drawing outside air into the chamber 1 to complete the test. This achieves the effect of rotating the interior panel while the air is being intaked, thereby increasing the test accuracy.

[0030] Mounting base 3 is fitted with mounting bearing 17, and mounting arm 4 is fixedly mounted on the inner ring of mounting bearing 17. Mounting arm 4 is movably mounted on mounting base 3 through mounting bearing 17.

[0031] The clamping mechanism includes a movable arm 5, a clamping block 6, a spring 7, and a mounting spring 8. The movable arm 5 is a cylindrical structure and is movably mounted on the mounting arm 4, penetrating one side wall of the mounting arm 4. The clamping block 6 is a hollow rectangular structure and is fixedly mounted on the movable arm 5. The spring 7 is an arc-shaped structure, and there are multiple springs 7. The springs 7 are located on the upper and lower sides inside the clamping block 6, and one end of the spring 7 is fixedly connected to the clamping block 6. The mounting spring 8 is located inside the mounting arm 4 and connected to the movable arm 5. Through the clamping mechanism, one end of the interior panel can be placed inside the clamping block 6. Since the spring 7 is elastic, it will deform and then squeeze and fix the interior panel through the released elastic force. Since there are two clamping mechanisms, the mounting spring 8 inside the clamping mechanism will be squeezed according to the size of the interior panel. The mounting spring 8 can also release the elastic force, thereby driving the two clamping mechanisms to clamp and position the interior panel.

[0032] A sealing gasket 18 is embedded between the cover plate 2 and the box body 1. The sealing gasket 18 can seal the gap between the box body 1 and the cover plate 2 when the box body 1 and the cover plate 2 are closed.

[0033] The specific working method is as follows:

[0034] The interior panel is clamped by the clamping mechanism, and then outside air is introduced into the interior of the box 1 through the air inlet 9. After the air is detected by the air detector 11, it leaves the interior of the box 1. During the movement of the air, it will come into contact with the interior panel. The air detector 11 can detect whether there is residual formaldehyde on the interior panel by detecting the air data.

[0035] Simultaneously, through the setting of the drive mechanism, after the interior panel is clamped by the clamping mechanism, the drive motor 12 can be started. The drive motor 12 drives the mounting arm 4 to rotate, which in turn drives the interior panel to rotate. The rotation of the interior panel increases the contact area with air, thereby increasing the test accuracy. At the same time, it drives the bevel ring 13 to rotate. The bevel ring 13 drives the transmission rod 14 to rotate through the transmission bevel 16. The transmission rod 14 then drives the fan blade 15 to rotate inside the air inlet 9, thereby generating suction inside the air inlet 9, and thus drawing outside air into the chamber 1 to complete the test. This achieves the effect of rotating the interior panel while the air is being intaked, thereby increasing the test accuracy.

[0036] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
