The door panel assembly is used to open and close the box body 1 to facilitate the test vehicle to enter and exit. The box body 1 is a rectangular parallelepiped, and a door opening 6 is opened on two opposite sides of the rectangular parallelepiped. The door panel assembly is arranged on the door opening 6. The door panel assembly is set to open and close automatically, and can be opened and closed from the side or from the top; a plurality of moving assemblies 2 are arranged on the load-bearing frame 7, and at least two types of moving assemblies 2 are arranged on each of the moving assemblies 2 for changing The environmental components of the internal environment of the box body 1 are used to simulate the real environment. For example, the lighting component 4 simulates the sunlight irradiating the test vehicle, the rain component 3 simulates the impact of rainy weather on the test vehicle, and the hail component simulates the impact of hail weather on the test vehicle. The mobile component 2 rotates at least one environmental component to the working area of ​​the load-bearing frame 7. When it is one environmental component, the simulated test environment is one. When there are two or more environmental components, the test box can be divided into areas to carry out tests of different functions. It is suitable for test pieces that occupy a relatively small area, so that one box can be used for multiple purposes.

[0029] The above-mentioned environmental components may also include heating components, refrigeration components, humidification components, etc. These environmental components can be arranged on the top of the box body 1, on the load-bearing frame 7 or on the side wall of the box body 1 as needed, and a simulated mixed test environment is used at the same time. In this scheme, the two environmental components of the lighting component 4 and the rain component 3 are mainly arranged on the load-bearing frame 7, and the structure of three, four or more environmental components can be realized through similar structures on the same surface or other surfaces, or can exist as fixed components on the other surfaces at the same time, and reach the test conditions through the drive of the circulating air duct; the lighting component 4 and the rain component 3 can be arranged at intervals or in a concentrated manner, for example, the interval arrangement is to arrange one or two rain components 3, and then arrange another lighting component 4; the concentrated arrangement is to arrange all the lighting components 4 together in a continuous manner, and the rain components 3 are arranged together in a continuous manner; the rain component 3 includes a nozzle and a hose connected to the nozzle, and the water pump supplies water to the nozzle through the hose; the lighting component 4 includes a lamp and wires, and the battery or the power grid provides electrical energy to the lamp through the wires.

The first belt 25 is fixed on the tank chain 22, and the first belt 25 is driven by the rotation of the driving pulley 24. The first belt 25 is fixedly connected to the tank chain 22, so the first belt 25 drives the tank chain 22 to rotate around the guide rail bracket 21; its driving assembly There are different forms of the structure. In the first form, a second belt 26 is arranged on the pulley 24, and the first motor 23 drives the pulley 24 to rotate through the second belt 26. At this time, the number of the first motors 23 is the same as the number of the moving components 2, that is, each first motor 23 controls one moving component 2; in the second form, the first motor 23 is arranged on the load-bearing frame 7, and all the pulleys 24 are driven by the same driving shaft. The first motor 23 drives the driving shaft, so that one motor controls all the moving components 2 at the same time; in the third form, multiple moving components 2 are controlled by one motor, for example, one motor corresponds to three moving components 2, so only a few motors are needed; in this scheme, the first structural form is adopted, and the corresponding control is individual, wherein the first motor 23 adopts a stepping motor.

[0031] like Figure 7 and Figure 8 The guide rail bracket 21 is composed of an upper first bracket 211, a lower second bracket 212, a left semi-arc third bracket 213 and a right semi-arc fourth bracket 214.

The roller 28 is arranged in the T-shaped slot 215 and rolls in the T-shaped slot 215, so that the tank chain 22 can run more smoothly; the diameter of the roller 28 is selected to be slightly smaller than the height of the T-shaped slot 215. At the same time, the roller 28 is made of rubber material, and there will be no up and down movement during smooth sliding, thereby reducing abnormal noise.

The reducer assembly includes a reducer 53 fixed on the top of the box body 1, a steering gear arranged on the screw rod 51, and a connecting rod connecting the reducer 53 and the steering gear. The second motor 52 outputs power to the connecting rod through the reducer 53, and the connecting rod drives the screw rod 51 to rotate through the steering gear; the number of screw rods 51 is based on It needs to be set up as needed and needs to be evenly distributed so that the force of the screw rod 51 pulling the load-bearing frame is evenly distributed, and the rise and fall are balanced. In this solution, the number of screw rods 51 is 6, and there are also multiple solutions for the number of second motors 51. The first is that the number of second motors 52 is also 6, and each screw rod 51 corresponds to 1 second motor 52, and 6 second motors 52 are controlled respectively to control the up and down movement of 6 screw rods 51. This method must ensure that the 6 second motors 52 move synchronously. If one of the second motors 52 fails, the lifting assembly 5 will be unbalanced, affecting the use effect; the second is to use one second motor 52 to drive 6 The screw rods 51 are evenly divided into two rows, and a single output steering device 54 is arranged on the screw rods 51 on both sides of each row, and a double output steering device 55 is arranged on the screw rod 51 in the middle. The single output steering device 54 and the double output steering device 55 in each row are connected by a first connecting rod 57, and a worm gear assembly 56 is arranged on the first connecting rod 57 in each row. The reducer 53 is connected to the worm gear assembly 56 through a second connecting rod 58, and the worm gear assembly 56 drives the first connecting rod 57 to rotate, and the power output by the second motor 52 enters the reducer 53, and the reducer 53 outputs the power to the two worm gears through the second connecting rod 58. On the wheel assembly 56, the two worm gear assemblies 56 correspond to the two rows of lead screws 51 respectively; and the worm gear assembly 56 has an input end and two output ends, the two output ends are divided into two power paths, the first path directly outputs power to the single output diverter 54 on one side, the single output diverter 54 drives the lead screw 51 to move up and down, and the second path outputs power to the middle double output diverter 55; the double output diverter 55 is also divided into two paths, the first path outputs power to the middle lead screw 51 and controls the lead screw 51 to move up and down, and the second path is output to the single output diverter 54 on the other side through the first connecting rod 57, and the single output diverter 54 drives the lead screw 51 to move up and down.

[0034] like Fig.10The load-bearing frame 7 shown is composed of a plurality of mutually perpendicular profiles, including a plurality of X-direction profiles 71 and a plurality of Y-direction profiles 72 on the horizontal plane. The plurality of X-direction profiles 71 are arranged at equal intervals, and the plurality of Y-direction profiles 72 located on the X-direction profiles 71 are also arranged at equal intervals. The X-direction profiles 71 and the Y-direction profiles 72 are spliced ​​together by a plurality of fixing parts.

[0035] In summary, the present invention realizes the movement of the position of the environmental component through the cooperation of the guide rail bracket 21 and the tank chain 22, and the required simulated environment can be selected according to the needs. At the same time, since the required environmental components are moved to the working surface only during work, the utilization rate of space can be greatly saved; the combination of multiple environmental components can be used to achieve the superposition of multiple environments in the test box to simulate the effect of a comprehensive environment; the lifting component 5 can realize the rise and fall of the load-bearing frame 7, and the test vehicles of different heights can be simulated.
