[0021] When it is necessary to detect the heat radiation of heat damage from the interiors of different vehicles, the four fan-shaped movable covers 32 on the tops of the four fan-shaped test combination boxes 3 are flipped open by hinges 31 and fixed blocks 322 respectively, and then a part of the interior panels on the four different vehicles is fixed by the vehicle interior panel positioning mechanism 33. After fixation, the fan-shaped movable covers 32 can be rotated and merged to stop when they are against the limit placement plate 34 on the side of the inner wall of the fan-shaped test combination box 3, and the sealing ring 321 on the outer wall of the hinge 31 is used to improve the sealing after merging.

[0022] like Figure 3 As shown, the vehicle interior trim panel positioning mechanism 33 includes a U-shaped clamping plate 331, which is fixedly installed on the bottom of the fan-shaped test combination box 3, and a threaded rod 332 is threadedly installed on one side of the U-shaped clamping plate 331 away from the heat radiation source mechanism 4, and a knob 333 is fixedly installed on one end of the threaded rod 332 away from the vertical part of the U-shaped clamping plate 331, and the other end of the threaded rod 332 is threadedly penetrated to the other side of the vertical part of the U-shaped clamping plate 331 away from the heat radiation source mechanism 4 and a pressing plate 334 is movably installed, and two sliding rods 335 are fixedly installed on one side of the pressing plate 334 away from the heat radiation source mechanism 4, and the other ends of the two sliding rods 335 are penetrated to the side of the vertical part of the U-shaped clamping plate 331 away from the heat radiation source mechanism 4 and a limiting disk 336 is fixedly installed;

[0023] After the interior panel is clamped on the U-shaped clamp 331, the knob 333 is rotated to drive the threaded rod 332 to rotate and move toward the interior panel clamped in the U-shaped clamp 331, so that the pressure plate 334 movably connected to one end of the threaded rod 332 uses two sliding rods 335 to slide stably with the U-shaped clamp 331 at right angles to the interior panel until the interior panel is squeezed and fixed so that it remains in a vertical state and can evenly receive the irradiation of the heat radiation source.

[0024] As Figure 4 、 Figure 5 shown, on one side of the sector test combination box 3 close to the heat radiation source mechanism 4, an irradiation door opening 36 penetrating through to the inner cavity is provided. Above the inner wall of one side of the sector test combination box 3 close to the heat radiation source mechanism 4, a motor cabin 35 is provided. Inside the inner cavity of the motor cabin 35, a motor 351 is fixedly installed. The output shaft of the motor 351 penetrates through to the inner cavity of the irradiation door opening 36 and is fixedly installed with a light-transmitting laminated glass 37. The four light-transmitting laminated glasses 37 have the same structure and are used to simulate automotive glass. Sealing rings II 371 are fixedly installed on the four side surfaces of the light-transmitting laminated glass 37. The light-transmitting laminated glass 37 is snap-fitted with the inner ring of the irradiation door opening 36. The heat radiation source mechanism 4 includes four support rods 41. At the top ends of the four support rods 41, a heat source irradiation box 42 is fixedly installed. Inside the inner cavity of the heat source irradiation box 42, a number of light-emitting resistance coils 43 are provided. The light-emitting resistance coils 43 are powered by an external power supply. At the center of the bottom of the heat source irradiation box 42, a rotary motor 44 is fixedly installed. The rotary motor 44 is powered by an external power supply through a wire. The output shaft of the rotary motor 44 is fixedly installed with a turntable 45. On the outer wall of the turntable 45, a vertical plate 46 is fixedly installed. Above one side of the vertical plate 46 away from the turntable 45, a wireless infrared thermometer 47 is fixedly installed. Below one side of the vertical plate 46 away from the turntable 45, a wireless formaldehyde detector 48 is fixedly installed. Both the wireless infrared thermometer 47 and the wireless formaldehyde detector 48 transmit the collected data through the built-in wireless signal transmission module;

[0025] Use a wire to pass through the top of the test platform 1 and connect to the heat source irradiation box 42 to supply power to and start the light-emitting resistance coils 43 inside it, making it emit light and heat, generating heat radiation, and using the light-transmitting laminated glasses 37 in the irradiation door openings 36 around the heat source irradiation box 42 to evenly irradiate the heat radiation on the inner cavities of the four sector test combination boxes 3, irradiating the erected interior trim panels, and synchronously increasing the temperature in the four sector test combination boxes 3. When detection is required, the motors 351 in the motor cabins 35 included in the four sector test combination boxes 3 can be respectively started, thereby driving the sealing rings II 371 to flip towards the inner cavity of the sector test combination box 3, exposing its interior through the irradiation door opening 36. Then, set a rotation amount of 90 degrees for the rotary motor 44 at the bottom of the heat source irradiation box 42, so that the wireless infrared thermometer 47 and the wireless formaldehyde detector 48 on the outer wall of the vertical plate 46 on one side of the turntable 45 detect the temperature on the interior trim panel in the inner cavity of the sector test combination box 3 and the formaldehyde content in the inner cavity of the sector test combination box 3. The detection results are then sent to the tester for observation through its built-in wireless transmission module, so that the heat damage heat radiation test can be quickly carried out on different interior trim panels in different sector test combination boxes 3. After the detection is completed, reverse the output shaft of the motor 351 by 90 degrees to reset the light-transmitting laminated glass 37 to seal the irradiation door opening 36, and the sealing ring II 371 can also improve the sealing performance.

[0026] The working principle of the vehicle heat damage and heat radiation test tooling will be specifically described below.

[0027] As Figures 1-5 shown, when it is necessary to detect the heat damage and heat radiation of different vehicle interiors, the four sector-shaped movable covers 32 on the top of the four sector-shaped test combination boxes 3 are respectively flipped and opened by using hinges 31 and fixed blocks 322. Then, a part of the interior trim panels of four different vehicles are respectively clamped onto the U-shaped clamping plates 331 in the inner cavities of the four sector-shaped test combination boxes 3. Then, the knob 333 is rotated to drive the threaded rod 332 to rotate and move towards the interior trim panel clamped in the U-shaped clamping plate 331, so that the pressing plate 334 movably connected to one end of the threaded rod 332 moves towards the interior trim panel stably along the vertical direction of the U-shaped clamping plate 331 by means of two sliding rods 335 until the interior trim panel is squeezed and fixed to keep it in a vertical state. Then, the sector-shaped movable cover 32 can be rotated and combined until it abuts against the limit placement plate 34 on the inner wall side of the sector-shaped test combination box 3 and stops. The sealing performance after combination is improved by using the sealing ring one 321 around the outer wall of the hinge 31. Then, the luminous resistance coil 43 in the heat source irradiation box 42 can be powered on and started by using a wire, so that it emits light and heat to generate heat radiation, and the heat radiation is evenly irradiated on the inner cavities of the four sector-shaped test combination boxes 3 through the light-transmitting laminated glass 37 in the irradiation door openings 36 around the heat source irradiation box 42, irradiating the erected interior trim panels, and synchronously increasing the temperature in the four sector-shaped test combination boxes 3. When detection is required, the motors 351 in the engine compartments 35 included in the four sector-shaped test combination boxes 3 can be respectively started, so as to drive the sealing ring two 371 to flip towards the inner cavity of the sector-shaped test combination box 3, so that its interior is exposed by using the irradiation door opening 36. Then, the rotation amount of 90 degrees is set for the rotary motor 44 at the bottom of the heat source irradiation box 42, so that the wireless infrared thermometer 47 and the wireless formaldehyde detector 48 on the outer wall of the vertical plate 46 on one side of the turntable 45 detect the temperature on the interior trim panel in the inner cavity of the sector-shaped test combination box 3 and the formaldehyde content in the inner cavity of the sector-shaped test combination box 3. The detection results are then sent to the tester for observation by using the built-in wireless transmission module, so that the heat damage and heat radiation tests can be quickly carried out on different interior trim panels in different sector-shaped test combination boxes 3. After the detection, the output shaft of the motor 351 is reversed by 90 degrees, so that the light-transmitting laminated glass 37 is reset to seal the irradiation door opening 36, and the sealing performance can also be improved by using the sealing ring two 371.

[0028] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
