Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a combustion testing device for interior parts of vehicles. Background Technology

[0002] Interior parts for vehicles typically require combustion tests. These tests are usually conducted in accordance with domestic and international standards. The test sample is subjected to a direct impact of a gas flame at a certain angle and for a certain duration. The self-ignition time and the size of the burn within a certain time are then observed, and the flame retardant properties of the material are judged based on the combustion phenomena.

[0003] In actual testing, different materials require different flame angles; even for materials of the same material, it is sometimes necessary to test their flame retardant performance at different burning angles. Therefore, existing technologies typically require the preparation of multiple flame nozzles at specific angles to meet the needs of combustion performance testing at different burning angles.

[0004] In the prior art, invention publication number CN214840976U discloses an angle-adjustable igniter. Its technical solution includes a shell, a base plate, an adjustment assembly, and an igniter. The adjustment assembly includes a rotating rod, a support rod, a fixed rod, an adjusting element, and a positioning element. The middle position of the adjusting element is slidably engaged with the top of the support rod. A protrusion is provided at the end of the adjusting element near the fixed rod, and the protrusion is slidably connected to the fixed rod. The igniter is located at the end of the adjusting element away from the fixed rod. One end of the positioning element is inserted into the protrusion, and the other end is inserted into the fixed rod. First, rotating the rotating rod allows the support rod to be adjusted up and down. Then, moving the protrusion up and down causes it to slide, allowing the support rod to move relative to the adjusting element towards or away from the igniter, adjusting the angle between the igniter and the top wall of the support rod. Using the positioning element to fix the protrusion allows adjustment of the ignition angle of the igniter. This technical solution adjusts the ignition angle of the igniter. However, since the upward combustion of the flame is a result of air flow, when the flame ignites, the surrounding air is heated. Because hot air is less dense than cold air, it rises, and other parts of the cold air flow in to replenish it. As the air rises, the flame is also carried upward. Therefore, no matter how the ignition angle of the igniter is adjusted, the flame will tilt upward with the air flow, which will affect the accuracy of the combustion angle and reduce the accuracy of the test. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a vehicle interior component combustion testing device that adjusts the flame burning angle by rotating the interior component to be tested.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: A combustion testing device for vehicle interior parts includes an ignition device and an interior part positioning device. The interior part positioning device includes a mounting box and a mounting frame assembly. The mounting frame assembly is located above the ignition device. The mounting frame assembly is connected to a drive mechanism disposed in the mounting box via a drive shaft. The drive mechanism drives the drive shaft to rotate. The mounting frame assembly has a mounting groove. A through hole penetrating the upper and lower surfaces of the mounting frame assembly is provided in the middle of the mounting groove. The interior part to be tested is placed in the mounting groove, and the part of the interior part to be tested corresponding to the through hole is used to contact the flame of the ignition device for combustion testing.

[0007] Furthermore, the mounting slot is provided with a clamping component for clamping the interior trim to be tested.

[0008] Furthermore, the clamping assembly includes a clamping plate located at the top of the inner side of the mounting groove.

[0009] Furthermore, a baffle is formed by extending the end of the movable column away from the clamping plate in all directions, and an elastic element is provided between the baffle and the outer wall of the mounting groove to facilitate the repositioning of the movable column.

[0010] Furthermore, the drive mechanism includes a drive motor, and a driving bevel gear is fixedly connected to the end of the output shaft of the drive motor.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] It should be noted that in the description of the technical solution of this utility model, some directional terms used to clearly describe the technical features of this utility model, such as "front", "rear", "upper", "lower", "top", "bottom", "inner", and "outer", are all in accordance with the orientation of the accompanying drawings of this utility model. Example

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, this embodiment of a vehicle interior trim combustion testing device includes an ignition device 7 and an interior trim positioning device. The interior trim positioning device includes a mounting box 3 and a mounting frame assembly 6. The bottom of the mounting box 3 is fixedly mounted on a placement plate 2, and the placement plate 2 is supported and fixed on a base 1 by a support column. The ignition device 7 is fixedly mounted on the base 1 and is equipped with an igniter 71 for ejecting flames. The mounting frame assembly 6 is located above the ignition device 7 and is connected to a drive mechanism 4 located inside the mounting box 3 via a drive shaft 5. The drive mechanism 4 drives the drive shaft 5 to rotate. Specifically, the mounting frame assembly 6 is provided with a mounting groove 62, and a through hole 61 penetrating the upper and lower surfaces of the mounting frame assembly 6 is provided in the middle of the mounting groove 62. The interior trim to be tested is placed in the mounting groove 62, and the part of the interior trim to be tested corresponding to the through hole 61 is used to contact the flame of the ignition device 7 for combustion testing.

[0019] To secure the interior trim to be tested in place, the mounting slot 62 is equipped with a clamping assembly 63 for pressing the interior trim against the surface. For example... Figure 5 As shown, the clamping assembly 63 includes a clamping plate 631 located at the top of the inner side of the mounting groove 62. An electromagnet is mounted on the clamping plate 631, which is made of a non-ferromagnetic material. The electromagnet is electrically connected to a power source, and its magnetism is controlled by switching the power supply on and off. A permanent magnet is located at a corresponding position at the bottom of the inner side of the mounting groove 62. A movable column 632 is fixedly connected to the clamping plate 631. A guide hole 64 is provided on the upper wall of the mounting groove 62, allowing the movable column 632 to pass through and reciprocate. One end of the movable column 632 passes through the corresponding guide hole 64 and extends to the outside of the mounting groove 62. The end of the movable column 632 away from the clamping plate 631 extends outwards to form a baffle. An elastic element 633 is provided between the baffle and the outer wall of the mounting groove 62 to facilitate the reset of the movable column 632. When the power is on, the electromagnet generates a magnetic pole opposite to that of the permanent magnet, which, under the action of magnetic force, drives the pressing plate 631 to move down toward the permanent magnet. The moving column 632 also moves along the guide hole 64. During the downward movement of the pressing plate 631, it overcomes the elastic force of the elastic element 633 until the interior to be tested is pressed firmly onto the bottom of the mounting groove 62. When the power is off, the magnetism of the electromagnet disappears, and the pressing plate 631 moves in the opposite direction and resets under the action of the rebound force of the elastic element 633, thereby releasing the pressing action of the interior to be tested. At this time, the interior to be tested can be taken out.

[0020] In this embodiment, the elastic element 633 is a return spring. One end of the return spring abuts against the baffle, and the other end abuts against the outer wall of the mounting groove 62. It is simple, reliable, flexible, and convenient. In addition, in order to further improve the clamping effect on the interior trim to be tested, this embodiment provides an anti-slip groove at the bottom of the mounting groove 62. The anti-slip groove is set along the entry or removal direction of the interior trim to be tested, which not only facilitates the installation of the interior trim to be tested, but also increases the friction during the clamping process, thereby improving the clamping reliability.

[0021] like Figure 4 As shown, the drive mechanism 4 includes a drive motor 41, which is located on top of the mounting box 3. A drive bevel gear 43 is fixedly connected to the end of the output shaft 42 of the drive motor 41. The drive bevel gear 43 meshes with a driven bevel gear 51 fixed to the end of the transmission shaft 5. The transmission shaft 5 is rotatably connected to the mounting box 3 via bearings. In this embodiment, the axis of the transmission shaft 5 is horizontally arranged, while the axis of the igniter 71 is vertically arranged. When the drive motor 41 starts, it drives the output shaft 42 to rotate, thereby causing the drive bevel gear 43 to rotate, which in turn causes the driven bevel gear 51 to rotate. This, in turn, causes the mounting frame assembly 6, which is fixedly connected to the transmission shaft 5, to rotate about the horizontal axis of the transmission shaft 5. The rotation of the mounting frame assembly 6 causes the interior trim to be tested mounted on it to rotate. This rotation adjusts the flame angle, thus meeting different production requirements.

[0022] This utility model discloses a combustion testing device for interior parts of a vehicle. The ignition device 7 is fixedly installed, and the mounting frame assembly 6 for mounting the interior parts to be tested is designed as a rotatable structure. The flame burning angle can be adjusted by rotating the interior parts to be tested. The structure is not only ingenious and reasonable, but also simple to manufacture, and the adjustment is more precise and easy to control.

[0023] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
