The side of the support platform 1 away from the fixed column 12 is provided with an inclined surface 14 so as to facilitate the transfer of vehicles onto the support platform 1.

Under the condition that the number of the test components 2 is multiple, one test component 2 is arranged at one test position 11, the test component 2 comprises a high attachment component 21, a plane roller component 22 and a pulley component 23, and the high attachment component 21, the plane roller component 22 and the pulley component 23 can be matched to test different performances of the vehicle.

Specifically, the high attachment assembly 21 cooperates with a wheel and is used to provide friction to the vehicle to simulate the vehicle's travel on a common road surface; the flat roller assembly 22 is configured to provide a wheel with a slip state, for example, when testing the performance of a part of the wheels of the vehicle, the remaining wheels can be placed on the flat roller assembly 22, and the wheels on the flat roller assembly 22 can drive the flat roller assembly 22 to rotate when rotating, so as to avoid the influence on the tested wheels. Referring to fig. 1 and 7, the pulley assembly 23 includes two sets of rollers 231 which are oppositely arranged, a first sensor 232 for measuring rotation of the rollers 231 is fixed on the rollers 231, a second sensor 233 for measuring a shelter is arranged on one side of the pulley assembly 23 close to the inclined plane 14, and the cooperation of the first sensor 232 and the second sensor 233 can accurately measure the time from the start of escaping to the end of escaping of the vehicle, so as to accurately describe the time required by the vehicle to escape, and embody the escaping capability of different vehicles.

For example, when the vehicle is in a trapping test, the first sensor 232 may be automatically triggered when the wheel drives the roller 231 to rotate, so as to obtain the start time of the trapping test, the second sensor 233 for measuring a blocking object is disposed on one side of the pulley assembly 23 close to the inclined plane 14, the vehicle may move in a direction close to the inclined plane 14 after trapping, and the signal emitted by the second sensor 233 may be automatically obtained the end time of the trapping test after being blocked, so as to accurately measure the time of the vehicle trapping, and accurately evaluate the trapping ability of the vehicle. In addition, because the four-wheel drive has outstanding driving experience and stability, the form of the performance test of the four-wheel drive can be many, for example, the traction force of single round or many rounds of test, and the whole vehicle performance test platform that provides through the embodiment of the application can test each item traction performance and the ability of getting rid of poverty of the four-wheel drive comprehensively.

The embodiment of the application provides whole car performance test platform includes brace table 1 and a plurality of test component 2, one test component 2 sets up in one test position 11, highly attach subassembly 21 and wheel cooperation and be used for providing frictional force for the vehicle, plane roller subassembly 22 is configured for providing the state of skidding for the wheel, loose pulley assembly 23 is including two sets of cylinders 231 of relative setting, be fixed with on the cylinder 231 and measure its pivoted first sensor 232, loose pulley assembly 23 is close to one side of inclined plane 14 is provided with the second sensor 233 that is used for measuring the shelter from, first sensor 232 with the cooperation of second sensor 233 can accurately measure the vehicle from getting rid of poverty to the time that gets rid of poverty and finishes, improves vehicle test's accuracy and comprehensiveness.

Alternatively, referring to fig. 5, the high attachment assembly 21 includes a high attachment surface 211 and a pressure sensor 212 disposed on one side of the high attachment surface 211, and the pressure sensor 212 is configured to determine the position of a wheel on the high attachment surface 211.

Specifically, when the vehicle is tested, different contact positions of the wheels and the high-attachment road surface 211 exert different pressures on the high-attachment road surface 211, the pressures of the wheels on the high-attachment road surface 211 at the different contact positions can be obtained through the arrangement of the pressure sensors 212, and the number of the pressure sensors 212 can be one or more, so that the purpose of accurately testing the positions of the wheels is achieved.

Alternatively, the pressure value acting on the pressure sensor 212 in the middle of the wheel is greater than the pressure value acting on the pressure sensor 212 on both sides of the wheel in the circumferential direction of the wheel.

Specifically, the circumferential direction of the wheel is in a symmetrical cambered surface structure, so that the acting force applied to the ground by the wheel in the middle is larger, and the acting force applied to the ground by the wheel is smaller as the wheel is closer to the two sides of the wheel. For example, the pressure sensors 212 may be disposed in the middle and both sides of one side of the high-adhesion road surface 211, and if the pressure of the wheel obtained by the middle pressure sensor 212 on the high-adhesion road surface 211 is greater than the pressure of the wheel obtained by the pressure sensors 212 on both sides on the high-adhesion road surface 211, the position of the wheel may be centered, and the accuracy of wheel position setting may be ensured.

In a specific embodiment, as shown in fig. 5, two pressure sensors 212 are symmetrically arranged on one side of the high attachment road surface 211, and if the pressures of the wheels obtained by the two pressure sensors 212 on the high attachment road surface 211 are equal, the wheels are centered, so that the accuracy of the vehicle performance test can be improved.

Alternatively, referring to fig. 6, the flat roller assembly 22 includes a plurality of rollers 221 arranged side by side, and in case that the wheels are rotated in the flat roller assembly 22, the rollers 221 are rotated in synchronization with the wheels.

Specifically, the roller 221 is arranged to simulate the slip condition of a vehicle on a low-attachment road surface, such as the slip condition of the vehicle on an icy or snowy road surface; in addition, when testing performances such as traction force of partial wheels of the vehicle, the remaining wheels can be placed on the plane roller assembly 22, and the wheels on the plane roller assembly 22 can drive the plane roller assembly 22 to rotate when rotating, so as to avoid the influence on the tested wheels.

Optionally, the diameter of the roller 221 is in the range of 60-80 mm.

Specifically, after a plurality of the rollers 221 are arranged side by side, the plane roller assembly 22 with a surface being close to a plane can be formed, so that the vehicle can perform the skid test on the surface of the plane roller assembly 22 with a low road surface, and the diameter of the roller 221 is directly related to the plane flatness of the plane roller assembly 22. For example, when the diameter of the roller 221 is too small, a relatively flat plane can be formed, but a large number of rollers 221 are required to be arranged side by side, which increases the complexity of assembly and increases the cost of the plane roller assembly 22; when the diameter of the roller 221 is too large, although a small number of rollers 221 may be used to form a plane, the gap between adjacent rollers 221 is too large, which reduces the flatness of the surface of the plane roller assembly 22. In a specific embodiment, as shown in fig. 6, the plane roller assembly 22 is composed of 8 rollers 221 side by side, and each roller 221 has a diameter of 80mm, so that the assembling structure of the plane roller assembly 22 can be simplified, and the surface flatness of the plane roller assembly 22 can be ensured.

Alternatively, referring to fig. 7, in the pulley assembly 23, the distance between the two sets of rollers 231 ranges from 320mm to 420 mm.

Specifically, the pulley assembly 23 may be configured to simulate a state of a wheel (single wheel or multiple wheels) of the vehicle being trapped in a pit, specifically, the wheel of the vehicle is trapped between two sets of the rollers 231, and then the whole vehicle performance testing platform provided by the embodiment of the present application is used to measure the escaping capability of the vehicle. And the distance between the two sets of rollers 231 is closely related to the depth of the wheel depression. Through to two sets of distance range's between the cylinder 231 regulation, can adjust the degree of depth that the wheel was absorbed in loose pulley assembly 23 in a flexible way, and then the vehicle of test different pitfall degree get rid of poverty ability, for example get rid of poverty time and when getting rid of poverty parameters such as the motor speed of vehicle.

Optionally, the diameter of the roller 231 ranges from 60 mm to 80mm, and the height of the roller 231 from the ground ranges from 20mm to 30 mm.

Specifically, the diameter of the drum 231 is greatly related to the easiness of the vehicle to get in and out of a pit. For example, when the diameter of the drum 231 is too small, the contact area between the wheels and the drum 231 is small when the vehicle is in a pit, which may cause the problem that the drum 231 is difficult to rotate when the vehicle is in a pit, and may cause an obstacle to the calculation of the time for the vehicle to be in a pit; when the diameter of the roller 231 is too large, namely the contact area between the wheels and the roller 231 is large after the vehicle sinks, the risk of skidding of the wheels of the vehicle is increased, and difficulty is caused in pit removal of the vehicle. And the ground clearance of the rollers 231 is matched with the distance between the two groups of rollers 231, so that the wheels can be prevented from directly contacting the ground, and the accuracy of the vehicle escaping test is ensured. In addition, referring to fig. 7, the pulley assembly 23 is further provided with side-preventing pulleys 234, and one of the side-preventing pulleys 234 is engaged with one of the rollers 231 to prevent the rollers 231 from sliding sideways.

Optionally, the first sensor 232 is a gyroscope or a hall sensor, and the second sensor 233 is a laser sensor, an ultrasonic sensor, an infrared sensor, or a radar sensor.

Specifically, the first sensor 232 may be automatically triggered when the wheel drives the roller 231 to rotate, so as to obtain the start time of the escaping test, that is, the first sensor 232 needs to accurately obtain the start time of the wheel rotating. For example, when the first sensor 232 is a hall sensor, the hall sensor can trigger a timer to start timing when the wheel drives the roller 231 to rotate, so as to accurately record the time when the vehicle is out of position. The signal emitted by the second sensor 233 is blocked by the wheel movement, and then the end time of the escaping test can be automatically obtained, for example, when the second sensor 233 is a laser sensor, the laser signal emitted by the laser sensor can be blocked when the wheel passes through the position. And then triggering the timer to finish timing so as to accurately record the time when the vehicle is out of the trouble.
