The vehicle driving simulation apparatus according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 11, a vehicle driving simulation apparatus according to an embodiment of the present invention is provided to simulate driving, which may be but is not limited to a game application scenario. The vehicle driving simulation apparatus includes a vehicle underframe 200, a moving frame 300, and a plurality of motion simulation mechanisms 100.

Specifically, the vehicle chassis 200 may be mounted on the ground or other fixture. The moving frame 300 may move with respect to the vehicle undercarriage 200, and preferably, the moving frame 300 may be located above the vehicle undercarriage 200.

A plurality of the motion simulation mechanisms 100 are dispersedly disposed between the vehicle under-frame 200 and the moving frame 300 to drive the moving frame 300 to simulate a predetermined vertical motion. That is, the motion simulation mechanism 100 may drive the motion frame 300 to move relative to the vehicle underframe 200, and when each of the simulated motion mechanisms operates according to a predetermined control manner, various bumping motions may be simulated.

Each of the motion simulation mechanisms 100 includes a first driving device provided on the vehicle underframe 200, and a link mechanism connected between the first driving device and the moving frame 300, and the link mechanism has elasticity such that the driving force of the first driving device is elastically transmitted to the moving frame 300 through the link mechanism.

That is, the first driving device is connected to the moving frame 300 through the link mechanism, and the link mechanism has elasticity, when the first driving device works, the driving force of the first driving device can be transmitted to the moving mechanism through the link mechanism, and since the link mechanism has elasticity, the driving force can be elastically transmitted to the moving frame 300, so that the moving frame 300 can be compliant and comfortable without being stiff and uncomfortable, in other words, the movement of the moving frame 300 can be closer to the bumpy feeling during real driving by using the linkage action of the link mechanism with elasticity.

According to the vehicle driving simulation apparatus provided by the embodiment of the invention, the plurality of motion simulation mechanisms 100 are used for driving the motion frame 300 to realize the motion with a plurality of degrees of freedom, each motion simulation mechanism 100 comprises the first driving device and the link mechanism, the first driving device is arranged on the vehicle underframe 200, the link mechanism is connected between the first driving device and the motion frame 300, and the link mechanism has elasticity, when the motion frame 300 is driven by the first driving device, the driving force of the first driving device is elastically transmitted to the motion frame 300 through the link mechanism, so that the link mechanism with the elasticity can simulate the actions such as more vivid jolt, and the immersion feeling and the comfortable feeling of a user can be enhanced, in addition, the elasticity of the link mechanism can play a damping effect, and the mechanical failure rate can be reduced.

Referring to fig. 1 to 2, in one embodiment of the present invention, there are four motion simulation mechanisms 100, two of the four motion simulation mechanisms 100 are spaced apart from each other at one side of the vehicle chassis 200 in the width direction, and the other two of the four motion simulation mechanisms 100 are spaced apart from each other at one side of the vehicle chassis 200 in the width direction, so as to simulate four wheels of a vehicle. Preferably, the vehicle underframe 200 and the moving frame 300 are rectangular, and the four motion simulation mechanisms 100 are respectively arranged between four corners of the vehicle underframe 200 and the moving frame 300.

It should be noted that, in the related art, for the simulation of the movement, a plurality of drivers are usually disposed at the bottom of the movement seat 500, and are driven by the plurality of drivers, and the drivers do not correspond to the wheels, and the movement sense of the simulation mode is obviously different from the movement sense of the real driving, so the reality sense is poor, and the user experience is not good.

In this embodiment, the four motion simulation mechanisms 100 are respectively and correspondingly installed on two sides of the vehicle chassis 200 to simulate four wheels of a vehicle, and in the simulation process, the road condition in the game scene can be combined to control the four motion simulation mechanisms 100 to correspond to the four wheels, so that when the four motion simulation mechanisms 100 act according to a predetermined control mode, more realistic feelings of bumpiness, vibration and the like in real driving can be simulated.

Referring to fig. 2, 4 and 6, in some embodiments of the present invention, an acceleration simulation mechanism 400 is further included, and the acceleration simulation mechanism 400 is disposed between the vehicle underframe 200 and the moving frame 300 to drive the moving frame 300 to simulate a predetermined motion in a horizontal direction.

That is to say, the acceleration simulation mechanism 400 can drive the motion frame 300 to move along the horizontal direction, so as to realize the simulation of the motion state in the horizontal direction, for example, acceleration simulation, and thus, the vehicle driving simulation device can simulate the acceleration of the vehicle, the simulation effect is better and vivid, and the user experience is better.

Referring to fig. 12 to 19, in an embodiment of the present invention, the link mechanism includes an adaptor 11, a floating arm 12, a damping shock absorber 13 and a link 14, wherein the adaptor 11 is connected to and driven by the first driving device, the floating arm 12 is disposed at one side of the first driving device, and the floating arm 12 is adapted to be connected to the moving frame 300; one end of the damping shock absorber 13 is pivoted with one end of the floating arm 12, and the other end of the damping shock absorber 13 is pivoted with the adaptor 11; one end of the connecting rod 14 is pivotally connected to the other end of the floating arm 12, and the other end of the connecting rod 14 is pivotally connected to the adaptor 11.

That is to say, in the present embodiment, the link mechanism mainly comprises the adaptor 11, the floating arm 12, the damping shock absorber 13 and the link 14, the damping shock absorber 13 is connected between one end of the floating arm 12 and the adaptor 11, the link 14 is connected between the other end of the floating arm 12 and the adaptor 11, the damping shock absorber 13 is pivotally connected between the floating arm 12 and the adaptor 11, and the link 14 is pivotally connected between the floating arm 12 and the adaptor 11, and in the link mechanism, the damping shock absorber 13 serves as one of the "rods" in the link mechanism and has a spring buffering effect.

When the first driving device works, the first driving device drives the adapter piece 11 to act, the damping shock absorber 13 is further driven to act through the adapter piece 11, and then the floating arm 12 and the moving frame 300 connected to the floating arm 12 are driven to move through the damping shock absorber 13, so that the moving frame 300 can generate simulation actions such as bumping and the like. Further, as described above, in the above link mechanism, since the damping damper 13 serves as one of the "rods" in the link mechanism and has a spring buffering action, when the driving force of the first driving means is elastically transmitted to the moving frame 300 by the damping damper 13, it is possible to ensure a smooth and comfortable movement of the moving frame 300 and a more realistic simulation action.

It can be understood that the pivot connections between the damping shock absorber 13 and the floating arm 12 and between the connecting rod 14 and the floating arm 12 and between the connecting piece 11 and the connecting piece 11 may be implemented by using a bolt, a nut and a pivot hole, taking the pivot connection between one end of the damping shock absorber 13 and the upper end of the floating arm 12 as an example, the upper end of the floating arm 12 and one end of the damping shock absorber 13 are both provided with the pivot hole, and the bolt is connected with the nut through a thread after passing through the pivot holes at the upper end of the floating arm 12 and one end of the damping shock absorber 13, so as to implement the pivot connection between one end of the damping shock absorber 13 and the upper end of the floating arm 12.

Optionally, the first driving device is a servo electric cylinder 10, and the servo electric cylinder 10 includes a cylinder body 101 and a push rod which is arranged on the cylinder body 101 and is retractable along the axis of the cylinder body 101, and the push rod has a push end 102, and the push end 102 extends vertically and is connected with the vehicle underframe 200. The adaptor 11 is fixed on the cylinder 101, for example, the adaptor 11 may be formed integrally with the cylinder 101, may be fixed on the cylinder 101 by welding, or may be fixed on the cylinder 101 by a fastening member such as a screw or a bolt.

When the servo electric cylinder 10 works, because the pushing end 102 of the push rod is fixed on the vehicle chassis 200, the push rod is not moved, the cylinder body 101 moves relative to the vehicle chassis 200, the cylinder body 101 further drives the adaptor 11 in the link mechanism to move, and thus the servo electric cylinder 10 can drive the moving frame 300 to move through the link mechanism. It should be noted that the specific structure and principle of the servo cylinder 10 are well known in the art and will not be described in detail herein.

It is understood that the first driving device may also adopt a linear motor, an oil cylinder, an air cylinder and other driving devices, and in the present invention, the embodiment of the first driving device is not limited.

Advantageously, the damping shock absorber 13 is located above said connecting rod 14, and the length of said damping shock absorber 13 is greater than the length of said connecting rod 14.

That is, the damping shock absorber 13 is located above the connecting rod 14, one end of the damping shock absorber 13 is pivotally connected to the upper end of the floating arm 12, the other end of the damping shock absorber 13 is pivotally connected to the adaptor 11, one end of the connecting rod 14 is pivotally connected to the lower end of the floating arm 12, and the other end of the connecting rod 14 is pivotally connected to the adaptor 11. When the cylinder body 101 of the servo cylinder 10 moves, the motion frame 300 is driven to move through the link mechanism, and the damping shock absorber 13 is positioned above the connecting rod 14, and the length of the damping shock absorber 13 is greater than that of the connecting rod 14, so that when the cylinder body 101 moves up and down, a vivid bumping and vibrating feeling can be transmitted through the damping shock absorber 13, meanwhile, the motion amplitude can be limited by utilizing the traction limitation of the connecting rod 14 on the damping shock absorber 13, and the problems that the damping shock absorber is easy to damage due to the large-amplitude swing of the damping shock absorber can be prevented.

Advantageously, the floating arm 12 has an initial position, when the floating arm 12 is in the initial position, the floating arm 12 is parallel to the servo cylinder 10. This initial position is the position in which the floating arm 12 is located in the absence of other external forces. That is, when the servo motor is installed vertically, the floating arm 12 is also kept in a vertical state, so that the damping shock absorber 13 is in an inclined state when being connected between the floating arm 12 and the adaptor 11, and when the damping shock absorber 13 is in the inclined state and the floating arm 12 is in the vertical state, and the cylinder body 101 moves up and down, the floating arm 12 can be ensured to simulate more vivid up-and-down bumping motion. In addition, the whole structure is more compact, and the installation is convenient.

Referring to fig. 14 to 15 and 17, in an embodiment of the present invention, the adaptor 11 includes a suspension flange 111 and an ear seat 112, wherein the suspension flange 111 is fixed to one side of the cylinder 101; the ear mount 112 is connected to the suspension flange 111 by a universal joint 15 so that the ear mount 112 is rotatable with respect to the suspension flange 111; the other end of the damping shock absorber 13 and the other end of the connecting rod 14 are pivotally connected to the ear seats 112, respectively.

In the related art, when the electric cylinder drives the moving frame 300, one of the common problems is that the servo electric cylinder 10 and other components are prone to interfere with each other, that is, the related art has a problem of mutual cylinder holding interference.

In this embodiment, the adaptor 11 mainly comprises a suspension flange 111 and an ear seat 112, the suspension flange 111 and the cylinder 101 are relatively fixed, the ear seat 112 and the suspension flange 111 are connected through a universal joint 15, and the damping shock absorber 13 and the connecting rod 14 are pivotally connected to the ear seat 112, so that during the motion simulation process, the rotation of the universal joint 15 can enable the ear seat 112 and the suspension flange 111 to rotate relatively when interference occurs, thereby eliminating the above-mentioned mutual cylinder interference problem. In addition, the ear base 112 and the suspension flange 111 are connected by the universal joint 15, so that the moving frame 300 can have a certain amount of movement in the horizontal direction, and further generate a sense of jolt in the direction, such as left-right shaking, and the like, thereby further improving the simulation effect.

More specifically, the suspension flange 111 has a through hole, the universal joint 15 includes a lock nut 151, a ball head sleeve 152 and a ball head shaft 153, and the ball head sleeve 152 is embedded in the through hole; the ball stud 153 has a first end, a second end and a ball stud 1531 located between the first end and the second end, the first end is fixedly connected to the ear seat 112, the second end is threaded to the lock nut 151 after penetrating through the through hole, and the ball stud 1531 is rotatably engaged with the ball stud 152.

In the example of fig. 14 to 15, the suspension flange 111 is vertically disposed, the through hole penetrates through the suspension flange 111 along the horizontal direction, the suspension flange 111 has a step therein, the ball socket 152 penetrates into the through hole from one side of the horizontal direction and abuts against the step, the ball socket 152 is pressed and fixed in the suspension flange 111 by a screw pressing sleeve 154 screwed on the suspension flange 111, the ball shaft 153 penetrates through the through hole, the ball head portion 1531 of the ball shaft 153 is rotatably fitted with the ball socket 152, the first end of the ball head portion 1531 is fixedly connected with the ear seat 112, for example, welded, screwed or integrally connected, and the second end penetrates through the through hole and then is screwed on the lock nut 151.
