It should be noted that the specific types of the rolling parameter detected by the first detecting member 40 and the rotation parameter detected by the second detecting member 50 are not limited herein.

As an alternative embodiment, the second detecting member 50 is used for detecting the movement information of the wheel, referring to fig. 2, the apparatus further includes a controller 70, the controller 70 is electrically connected to the second detecting member 50, and the controller 70 is used for receiving the movement information detected by the second detecting member 50 and controlling each roller 32 to move according to the movement information.

The specific content of the motion information is not limited herein, and the motion information may also be referred to as a rotation parameter, which may be specifically referred to as a corresponding expression of the rotation parameter hereinafter.

In the embodiment of the present disclosure, the controller receives the motion information of a certain wheel detected by the second detecting element 50, and can control other wheels to move according to the motion information, so as to ensure that the motion information of the wheels of the vehicle 100 is synchronized well, and further meet the requirements when performing various working condition simulations.

It should be noted that a certain wheel detected by the second detecting element 50 may refer to a rear wheel of the vehicle 100, and at this time, the vehicle 100 may be a rear-drive vehicle, so that the controller 70 may control the front wheel to move with the same movement information, that is, the working condition simulation of the rear-drive vehicle is realized; similarly, one of the wheels detected by the second detecting element 50 may be a front wheel of the vehicle 100, and in this case, the vehicle 100 may be a front-drive vehicle, so that the controller 70 may control the rear wheel to move with the same movement information, thereby implementing the condition simulation of the front-drive vehicle.

In addition, the controller 70 may control each wheel to move with different motion information, so that simulation of more operating conditions may be achieved. For example: a simulation of the turning behavior of the vehicle 100 may be achieved.

As an alternative embodiment, referring to fig. 3, a driving motor 322 is disposed on each roller 32, the driving motor 322 is electrically connected to the controller 70, and the controller 70 controls the driving motor 322 to move according to the motion information, so as to drive each roller to move according to the motion information.

In this way, the controller 70 controls the driving motor 322 to move according to the movement information, and causes the driving motor 322 to drive the drum to move according to the movement information, so that the driving effect on the drum can be more accurate. The controller 70 may also be referred to as a system console or system center console.

In addition, the position of the driving motor 322 on the drum 32 is not limited herein, for example: the driving motor 322 may be disposed at least one end of the roller 32, or the driving motor 322 may also be disposed in the roller 32 in a penetrating manner, that is, the roller 32 may be sleeved on the driving motor 322, and may also be referred to as the driving motor 322 disposed in the roller 32, so that the volume of the whole wheel condition simulation apparatus may be reduced.

As an alternative embodiment, the first detecting element 40 is configured to detect a linear velocity of the wheel, and the second detecting element 50 is configured to detect a rotation angle of the wheel, that is, it may be understood that the motion information includes a rotation angle of the vehicle 100.

In this way, the linear velocity and the rotation angle of the wheel can be detected by the first detecting part 40 and the second detecting part 50 respectively, and the arrangement positions of the first detecting part 40 and the second detecting part 50 are different, so that the flexibility of the detection mode of the linear velocity and the rotation angle of the wheel and the reliability of the detection result are improved.

It should be noted that, since the size of the drum 32 is generally a certain value, for example: the radius of the drum 32 is usually a fixed value, and the outer surface linear velocity of the drum 32 can be calculated from the rotational velocity of the drum 32 and the radius of the drum 32 on the basis of the radius of the drum 32 and the rotational velocity of the drum 32 detected by the second detecting member 50, and the outer surface of the wheel abuts against the outer surface of the drum 32, so that the outer surface linear velocity of the drum 32 can be equivalent to the linear velocity of the wheel.

In addition, since the fixing bracket 31 is fixedly connected to the second surface of the second turntable 20 and the roller 32 is disposed on the fixing bracket 31, referring to fig. 2, the wheel of the vehicle 100 abuts against the roller 32, so that when the second turntable 20 and the first turntable 10 rotate relatively, it can be understood that the wheel rotates relatively with the first turntable 10, and since the first detecting member 40 is disposed toward at least one of the first turntable 10 and the second turntable 20, the rotation angle of the first turntable 10 or the second turntable 20 detected by the first detecting member 40 can also be understood as the rotation angle of the wheel.

It should be noted that the specific types of the first detecting member 40 and the second detecting member 50 are not limited herein, for example: the first and second detecting members 40 and 50 may be rotation angle sensors or wheel speed sensors.

As an alternative embodiment, at least one of the first detecting member 40 and the second detecting member 50 is an encoder.

In this way, since the detection principle of the encoder is simple and reliable, the reliability of the detection results of the rolling parameter and the rotation parameter of the wheel by the first detecting member 40 and the second detecting member 50 is high, and the use cost of the encoder is low, so that the use cost is reduced.

It should be noted that the orientation of the first detecting member 40 is not limited herein, and for example: the first detecting member 40 may be disposed toward the first rotary disk 10, and the first detecting member 40 is used for detecting a rotation parameter of the first rotary disk 10; the first detecting member 40 may be disposed toward the second turntable 20, and the first detecting member 40 is configured to detect a rotation parameter of the second turntable 20; of course, the first detecting member 40 may be disposed toward the connection between the first rotating disk 10 and the second rotating disk 20, and the first detecting member 40 is used to detect the rotation parameters of the first rotating disk 10 and the second rotating disk 20.

As an alternative embodiment, when the second rotary table 20 rotates relative to the first rotary table 10, the first detecting member 40 faces the edge of the second rotary table 20.

In this way, the second rotary table 20 is closer to the wheel than the first rotary table 10, and therefore, when the first detecting member 40 is disposed toward the edge of the second rotary table 20, the error between the rotation parameter of the wheel detected by the first detecting member 40 and the actual rotation parameter of the wheel can be made smaller, thereby improving the accuracy of the result of the rotation parameter of the wheel detected by the first detecting member 40.

It should be noted that the first detecting member 40 and the edge of the second rotating disk 20 may be disposed at an interval, and of course, the first detecting member 40 and the edge of the second rotating disk 20 may be connected by a connecting member.

As an alternative embodiment, when the first detecting member 40 is an encoder, the first detecting member 40 is engaged with the edge of the second rotating disk 20 through a gear.

In this way, since the first detecting member 40 is engaged with the edge of the second rotating disk 20 through the gear, and the output shaft of the first detecting member 40 can also be driven by the gear to rotate, the rotation parameter of the wheel can be determined by detecting the rotation parameter of the output shaft, so as to further reduce the error of the detection result of the rotation parameter of the wheel, i.e. further improve the accuracy of the detection result of the rotation parameter of the wheel.

It should be noted that the wheel operating condition simulation device in the embodiment of the present disclosure can improve the time consumed for switching between different operating conditions, and the wheel does not need to be detached from the vehicle 100, so as to realize the simulation of the pivot operating condition of the wheel.

In addition, wheel operating mode analogue means can also include the display, and the display is connected with first detection piece 40 and second detection piece 50 electricity respectively, and like this, the display can be used for showing the data that first detection piece 40 and second detection piece 50 detected to make the user can more audio-visual observation above-mentioned data, reinforcing user experience.

The specific shapes of the first rotating disk 10 and the second rotating disk 20 are not limited herein, for example: the first rotating disk 10 and the second rotating disk 20 are both circular rotating disks, or the first rotating disk 10 and the second rotating disk 20 are both rectangular rotating disks, or one of the first rotating disk 10 and the second rotating disk 20 is a circular rotating disk, and the other of the first rotating disk 10 and the second rotating disk 20 is a rectangular rotating disk.

It should be noted that the driving relationship between the first rotary disk 10 and the second rotary disk 20 is not limited herein, for example: as an alternative embodiment, the first rotary disk 10 rotates, and the second rotary disk 20 is fixed, so that the relative rotation between the first rotary disk 10 and the second rotary disk 20 is realized; as another alternative, the first rotary table 10 is fixed, the second rotary table 20 is fixed, and the relative rotation between the first rotary table 10 and the second rotary table 20 can also be realized; as another alternative, the first rotary disk 10 and the second rotary disk 20 can rotate relatively at the same time, and the rotation directions of the first rotary disk 10 and the second rotary disk 20 are opposite, so that the relative rotation between the first rotary disk 10 and the second rotary disk 20 can be realized.

In addition, when the wheel is switched from the second state to the first state, it can be understood that: at this time, the wheel of the vehicle 100 finishes the condition simulation, and the wheel needs to leave the wheel condition simulation device, so that the telescopic mechanism 33 is in the extended state, and the telescopic mechanism 33 abuts against the wheel, that is, the wheel abuts against the telescopic mechanism 33 and the roller 32 simultaneously, and the friction force applied to the wheel is increased, so that the wheel is separated from the roller 32 more quickly and conveniently.
