A single test device can be used to simulate a variety of different road surfaces, and tests on a variety of road surfaces can be achieved, saving the space required for vehicle testing.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. By driving the adjustment slider to slide, the flatness of the test bench surface is changed, so that the test bench can simulate roads of different flatness to test the dynamic performance of vehicles on roads of different flatness. A single test device can simulate and test multiple road surfaces, saving space required for vehicle testing. The temperature control device solidifies the solidified liquid inside the deformation coating layer by cooling, so that the entire test platform is solidified, making it easier to simulate the road surface. At the same time, the solidification of the solidified liquid can further fix the position of the adjustment slider. When the adjustment slider needs to be driven to slide, the adjustment slider can slide and adjust when the solidified liquid liquefies.

[0019] 2. One end of the mounting frame is hinged to the base, and an adjustment member is provided between the other end of the mounting frame and the base. The adjustment member drives the mounting frame to rotate on the base. Adjustment of the adjustment member drives the rotation of the test bench, allowing the test bench to simulate roads of different slopes for vehicle testing, further expanding the test bench's simulation range and saving space required for testing on different road surfaces.

[0020] 3. When the adjusting member drives the mounting frame to rotate, the angle of the mounting frame changes, causing the contact area between the adjusting member and the mounting frame to gradually decrease and the pressure to gradually increase. The provision of the elastic block can deform to make the contact between the end of the adjusting member contacting the mounting frame and the mounting frame closer, thereby reducing the probability of the contact area between the adjusting member and the mounting frame decreasing and the pressure increasing due to the rotation of the mounting frame, thereby reducing the probability of damage to the mounting frame or the adjusting member when adjusting the angle of the mounting frame;

[0021] 4. The extension of the piston rod of the driving cylinder can cause the adjustment slider to slide through the driving rod, so that the corresponding position of the test bench surface is convex due to the abutment deformation of the driving slider, which changes the overall flatness of the test bench surface. When the piston rod of the driving cylinder is retracted, the adjustment slider is reset under the action of the reset spring;

[0022] 5. The driving motor drives the driving roller to rotate, and the driving roller drives the driving cam to rotate, thereby driving the adjusting slider to slide, so that the corresponding position of the test bench surface is convex due to the abutment deformation of the driving slider, so that the overall flatness of the test bench surface changes. When the driving cam rotates and disengages from the driving rod, the adjusting slider is reset under the action of the reset spring. BRIEF DESCRIPTION OF THE DRAWINGS

The test bench 2 is fixed to the mounting frame 8. The test bench 2 is mounted on the base 1 through the mounting frame 8. A fixing ring 16 is welded on the deformation coating 22 of the test bench 2. The fixing ring 16 is sleeved on the mounting frame 8 and fixed to the mounting frame 8 by bolts. A plurality of limiting rods 17 are provided on both sides of the width direction of the mounting frame 8. The limiting rods 17 on both sides of the width direction of the mounting frame 8 are respectively in contact with the two sides of the width direction of the test bench 2. The limit rod 17 is also used as a railing on both sides of the width direction of the test bench 2 to reduce the probability of the vehicle falling from both sides of the width direction of the test bench 2 during vehicle testing. One end of the mounting frame 8 in the length direction is hinged to the base 1, and an adjusting member 13 is provided between the other end of the mounting frame 8 in the length direction and the base 1. The adjusting member 13 drives the mounting frame 8 to rotate on the base 1. The adjustment of the adjusting member 13 can drive the rotation of the test bench 2, so that the test bench 2 simulates roads with different slopes to test vehicles, further improving the simulation range of the test bench 2 and saving the space required for testing on different road surfaces; the adjusting member 13 is an adjusting electric cylinder, and a plurality of adjusting electric cylinders are arranged in the length direction of the mounting frame 8 away from one end of the mounting frame 8 hinged to the base 1. When the overall length of the test bench 2 is long, a plurality of adjusting electric cylinders can also be arranged in the middle position of the base 1. One end of the adjusting electric cylinder is fixed to the base 1, and the other end abuts against the end of the mounting frame 8 facing the base 1, so that the adjusting electric cylinder is convenient for synchronous driving; the adjusting member 13 is fixed with an elastic block 14 at the abutting end of the mounting frame 8. The elastic block 14 is a rubber with deformation ability. Rubber block, when the adjusting member 13 drives the mounting frame 8 to rotate, the angle of the mounting frame 8 changes, resulting in the area where the adjusting member 13 abuts against the mounting frame 8 gradually becoming smaller and the pressure gradually increasing. The setting of the elastic block 14 can make the adjusting member 13 abut against one end of the mounting frame 8 more tightly through deformation, reducing the probability that the abutment area between the adjusting member 13 and the mounting frame 8 becomes smaller and the pressure increases after the mounting frame 8 rotates, thereby reducing the probability of the mounting frame 8 or the adjusting member 13 being damaged by excessive pressure when adjusting the angle of the mounting frame 8.

The number of the driving cylinders 91 is the same as the number of the adjusting sliders 3 and is one-to-one corresponding to the driving slider arrangement. One end of the driving cylinder 91 is fixed on the mounting frame 8, and the other end is separated from the deformation coating by the deformation coating. The layer 22 abuts against the driving rod 15, and the extension of the piston rod of the driving cylinder 91 can cause the adjusting slider 3 to slide through the driving rod 15, so that the corresponding position of the surface of the test bench 2 is convex due to the abutment deformation of the driving slider, so that the overall flatness of the surface of the test bench 2 changes; a return spring 12 is provided between the frame 21 and the adjusting slider 3, and the return spring 12 drives the adjusting slider 3 to slide toward the direction close to the base 1. When the piston rod of the driving cylinder 91 is retracted, the adjusting slider 3 is reset under the action of the return spring 12.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 The base 1 is provided with a plurality of placement grooves 18, in which a counterweight block 19 is placed. The counterweight block 19 is made of metal with a relatively high density. The setting of the counterweight block 19 can improve the placement stability of the base 1, thereby reducing the probability of the detection equipment tipping over.

[0038] The implementation principle of the embodiment of the present application is as follows: according to the required road surface flatness, the corresponding driving electric cylinder is adjusted, and the corresponding driving slider is adjusted by the driving electric cylinder so that the surface of the test bench 2 is deformed by the driving slider to form a road surface of the required flatness. After the surface flatness adjustment of the test bench 2 is completed, the temperature control device 7 is used to cool down the solidification liquid to solidify the test bench 2 as a whole, and then the vehicle is guided to enter the test platform for performance testing through the guide platform. During the test, the temperature control device 7 needs to be strengthened and adjusted to a temperature lower than the solidification temperature of the solidification liquid. For example, when the solidification liquid is water in this embodiment, the temperature setting of the temperature control device 7 during the test is as follows: The temperature is between -20°C and -90°C, preferably -50°C, so as to reduce the probability that the friction generated by the wheels during vehicle testing will cause the temperature of the test bench 2 to rise and the coagulation liquid to liquefy; after the vehicle is tested on a road surface with a certain flatness, the vehicle is driven out of the test bench, and then the coagulation liquid is liquefied by the temperature control device 7, and the surface flatness of the test bench 2 is adjusted before testing again; when the performance of the vehicle on roads with different slopes needs to be tested, the mounting frame 8 is driven by the driving cylinder 91 to rotate to different angles on the base 1 to simulate roads with different slopes, and then the vehicle is driven into the test bench 2 for testing.

[0039] Example 2:

[0040] The difference between this embodiment and embodiment 1 is that the driving mechanism 9 of this embodiment is different from that of embodiment 1.

[0041] Reference Figure 5 and Figure 6 The driving mechanism 9 includes a driving motor 92, a driving roller 93 and a driving cam 94. There are several driving motors 92. The number of driving motors 92 is the same as the number of rows of the adjusting slider 3 in the length direction of the frame 21. Each driving motor 92 corresponds to a row of adjusting sliders 3. Several driving motors 92 are evenly arranged in the length direction of the mounting frame 8. Several driving rollers 93 are arranged corresponding to the driving motors 92. A driving roller 93 is connected to the rotating shaft of each driving motor 92. Several driving cams 94 are provided. The driving cams 94 are detachably arranged corresponding to the adjusting slider 3. The driving cam 94 is placed on the driving roller 93, and the driving cam 94 is in contact with the driving rod 15 of the corresponding adjusting slider 3 through the deformation coating layer 22. The driving motor 92 drives the driving roller 93 to rotate, and the driving roller 93 rotates with the driving cam 94 to drive the adjusting slider 3 to slide, so that the corresponding position of the surface of the test bench 2 is convex due to the abutment deformation of the driving slider, so that the overall flatness of the surface of the test bench 2 changes; a return spring 12 is provided between the frame 21 and the adjusting slider 3, and the return spring 12 drives the adjusting slider 3 to slide toward the direction close to the base 1. 2 The driving adjustment slider 3 slides toward the direction close to the base 1. When the driving cam 94 rotates and disengages from the driving rod 15, the adjustment slider 3 is reset under the action of the reset spring 12. The driving roller 93 is a polygonal roller. In this embodiment, the driving roller 93 is a roller with a hexagonal cross section. The polygonal driving roller 93 can reduce the probability of the driving cam 94 slipping when the driving roller 93 rotates, so that the driving cam 94 can rotate more accurately with the driving roller 93. A reinforcement ring 10 is fixed on the driving cam 94. The reinforcement ring 10 is sleeved on the driving roller 93. 10 is threadedly connected with a reinforcing bolt 11, which passes through the reinforcing ring 10 and abuts against the driving roller 93. The driving cam 94 is reinforced by tightening the reinforcing bolt 11 to reduce the probability of the driving cam 94 slipping due to external force. Loosening the driving cam 94 can facilitate the adjustment of the position of the driving cam 94, and the driving cam 94 can also be disassembled, so that the driving cam 94 can be disassembled and assembled according to the actual adjustment slider 3. At the same time, driving cams 94 of different sizes can also be installed according to the different slip degrees of the same row of adjustment sliders 3.

[0042] The implementation principle of the embodiment of the present application is as follows: according to the required road surface flatness, the corresponding driving electric cylinder is adjusted, and the corresponding driving slider is adjusted by the driving electric cylinder so that the surface of the test bench 2 is deformed by the driving slider to form a road surface of the required flatness. After the surface flatness adjustment of the test bench 2 is completed, the temperature control device 7 is used to cool down the solidification liquid to solidify the test bench 2 as a whole, and then the vehicle is guided to enter the test platform for performance testing through the guide platform. During the test, the temperature control device 7 needs to be strengthened and adjusted to a temperature lower than the solidification temperature of the solidification liquid. For example, when the solidification liquid is water in this embodiment, the temperature setting of the temperature control device 7 during the test is as follows: The temperature is between -20°C and -90°C, preferably -50°C, so as to reduce the probability that the friction generated by the wheels during vehicle testing will cause the temperature of the test bench 2 to rise and the coagulation liquid to liquefy; after the vehicle is tested on a road surface with a certain flatness, the vehicle is driven out of the test bench, and then the coagulation liquid is liquefied by the temperature control device 7, and the surface flatness of the test bench 2 is adjusted before testing again; when the performance of the vehicle on roads with different slopes needs to be tested, the mounting frame 8 is driven by the driving cylinder 91 to rotate to different angles on the base 1 to simulate roads with different slopes, and then the vehicle is driven into the test bench 2 for testing.

[0043] Example 3:

[0044] The difference between this embodiment and embodiment 1 is that the adjusting member 13 of this embodiment is different from that of embodiment 1.

[0045] Reference Figure 7 The adjusting member 13 is a jack, one end of which is fixed to the base 1, and the other end is in contact with the mounting frame 8 toward the end of the base 1. The jack has a more stable support effect than the electric cylinder, but when multiple jacks are set, the synchronization between the jacks is relatively poor compared to multiple electric cylinders; the adjusting member 13 is fixed with an elastic block 14 at one end abutting the mounting frame 8. The elastic block 14 is a rubber block with deformation ability. When the adjusting member 13 drives the mounting frame 8 to rotate, the angle of the mounting frame 8 changes, resulting in the area of ​​the adjusting member 13 abutting against the mounting frame 8 gradually becoming smaller and the pressure gradually increasing. The setting of the elastic block 14 can make the adjusting member 13 abut against one end of the mounting frame 8 more tightly abutting against the mounting frame 8 through deformation, reducing the probability of the abutment area of ​​the adjusting member 13 and the mounting frame 8 becoming smaller and the pressure increasing after the mounting frame 8 rotates, thereby reducing the probability of damage to the mounting frame 8 or the adjusting member 13 when adjusting the angle of the mounting frame 8.

[0046] The implementation principle of the embodiment of the present application is as follows: the corresponding driving cam 94 is adjusted according to the road surface flatness to be tested, and the corresponding driving slider is adjusted by the driving cam 94 so that the surface of the test bench 2 is deformed by the driving slider to form a road surface of the required flatness. After the surface flatness adjustment of the test bench 2 is completed, the temperature control device 7 is used to cool down the solidification liquid to solidify the test bench 2 as a whole, and then the guide platform guides the vehicle into the test platform for performance testing. During the test, the temperature control device 7 needs to be strengthened and adjusted to a temperature lower than the solidification temperature of the solidification liquid. For example, when the solidification liquid is water in this embodiment, the temperature control device 7 is set to the same temperature as the solidification liquid. The temperature is set between -20°C and -90°C, preferably -50°C, so as to reduce the probability that the friction generated by the wheels during vehicle testing will cause the temperature of the test bench 2 to rise and the coagulation liquid to liquefy; after the vehicle is tested on a flat road surface, the vehicle is driven out of the test bench, and then the coagulation liquid is liquefied by the temperature control device 7, and the surface flatness of the test bench 2 is adjusted before testing again; when it is necessary to test the performance of the vehicle on roads with different slopes, the mounting frame 8 is driven by the jack to rotate to different angles on the base 1 to simulate roads with different slopes, and then the vehicle is driven into the test bench 2 for testing.
