[0082] The motion simulation mechanism and vehicle driving simulation device according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0083] Reference Figures 1 to 8 As shown, the motion simulation mechanism provided according to an embodiment of the present invention includes a driving device 10 , an adapter 11 , a floating arm 12 , a damping shock absorber 13 and a connecting rod 14 .

[0084] Specifically, the driving device 10 is suitable for being installed on a fixed carrier 20. Exemplarily, the driving device 10 is a servo electric cylinder, which includes a cylinder body 101 and a push rod provided on the cylinder body 101 and retractable along the axis of the cylinder body 101, wherein the push rod has a push end 102, and the push end 102 is suitable for being connected to the fixed carrier 20. That is to say, in a specific application, the push end 102 of the push rod can be connected and fixed to the fixed carrier 20, and the fixed carrier 20 can be a fixed part in the application scene, for example, when the motion simulation mechanism is applied to a vehicle driving simulation scene, the fixed carrier 20 can be a vehicle chassis, etc. When the servo electric cylinder is working, since the push end 102 of the push rod is fixed on the fixed carrier 20, the push rod does not move, and the cylinder body 101 moves relative to the fixed carrier 20. It should be noted that the specific structure and principle of the servo electric cylinder are known technologies, which are well known to those skilled in the art and will not be described in detail here.

[0085] The adapter 11 is connected to the driving device and driven by the driving device. For example, the adapter 11 is fixed on the cylinder body 101. For example, the adapter 11 can be formed as a whole with the cylinder body 101, or can be fixed on the cylinder body 101 by welding, or can be fixed on the cylinder body 101 by fasteners such as screws and bolts. The floating arm 12 is provided on one side of the driving device, and the floating arm 12 is suitable for connecting with the moving platform 21. That is to say, in a specific application, the floating arm 12 is used to connect to the moving platform 21. For example, when the vehicle driving simulation scene is used, the moving platform 21 can be a moving frame located above the vehicle chassis.

[0086] One end of the damping shock absorber 13 is pivoted to one end of the floating arm 12 , and the other end of the damping shock absorber 13 is pivoted to the adapter 11 ; one end of the connecting rod 14 is pivoted to the other end of the floating arm 12 , and the other end of the connecting rod 14 is pivoted to the adapter 11 .

[0087] That is to say, the damping shock absorber 13 is connected between one end of the floating arm 12 and the adapter 11, and the connecting rod 14 is connected between the other end of the floating arm 12 and the adapter 11, and the damping shock absorber 13 and the floating arm 12 and the adapter 11, and the connecting rod 14 and the floating arm 12 and the adapter 11 are all pivotally connected. The damping shock absorber 13, the floating arm 12 and the connecting rod 14 form a "connecting rod mechanism", in which the damping shock absorber 13, as one of the "rods" in the connecting rod mechanism, has a spring buffering effect.

[0088] When the servo electric cylinder is working, the cylinder body 101 moves relative to the fixed carrier 20, and the cylinder body 101 further drives the connecting rod mechanism to move through the adapter 11, and then drives the moving platform 21 to move through the connecting rod mechanism. In this way, since the cylinder body 101 is connected to the moving platform 21 through the connecting rod mechanism, the linkage effect of the connecting rod mechanism can make the moving platform 21 move and produce simulated actions such as bumps. In addition, as mentioned above, in the above-mentioned connecting rod mechanism, since the damping shock absorber 13 is one of the "rods" in the connecting rod mechanism and has a spring buffering effect, when the movement of the cylinder body 101 is transmitted to the moving platform 21 through the connecting rod mechanism, the movement of the moving platform 21 is more smooth and comfortable.

[0089] It can be understood that the pivot connection between the damping shock absorber 13 and the floating arm 12 and the adapter 11, and between the connecting rod 14 and the floating arm 12 and the adapter 11 can be realized by the cooperation of bolts, nuts and pivot holes. 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, pivot holes are provided at the upper end of the floating arm 12 and one end of the damping shock absorber 13. The bolts pass through the pivot holes at the upper end of the floating arm 12 and one end of the damping shock absorber 13 and are threadedly connected with the nuts, thereby realizing the pivot connection between one end of the damping shock absorber 13 and the upper end of the floating arm 12.

[0090] The motion simulation mechanism provided according to the embodiment of the present invention can be applied to vehicle driving simulation, and comprises a floating arm 12, a shock absorber and a connecting rod 14. An adapter 11 is provided on the cylinder body 101 of the servo electric cylinder. One end of the damping shock absorber 13 is pivoted to one end of the floating arm 12, and the other end of the damping shock absorber 13 is pivoted to the adapter 11. One end of the connecting rod 14 is pivoted to the other end of the floating arm 12, and the other end of the connecting rod 14 is pivoted to the adapter 11. In this way, when the moving platform 21 is driven by the servo electric cylinder to simulate the action, the power output by the servo electric cylinder is transmitted to the floating arm 12 through the shock absorber and the connecting rod 14, and then transmitted to the moving platform 21 by the floating arm 12. In this way, more realistic bumpy actions can be simulated, thereby enhancing the user's sense of immersion and comfort. In addition, the shock absorption effect can be used to reduce the mechanical failure rate.

[0091] It is understandable that the driving device 10 can also be a driving device such as an oil cylinder, a linear motor, or a pneumatic cylinder.

[0092] Reference Figures 5 and 6As shown, in one embodiment of the present invention, when the servo electric cylinder is placed upright, the damping shock absorber 13 is located above the connecting rod 14, and the length of the damping shock absorber 13 is greater than the length of the connecting rod 14. That is to say, with the vertical direction as the reference direction, when the servo electric cylinder is kept upright, 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, and the other end of the damping shock absorber 13 is pivotally connected to the adapter 11, while 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 adapter 11.

[0093] In specific applications, the servo electric cylinder can be installed vertically. Preferably, the pushing end 102 of the push rod faces downward and is connected and fixed to the fixed carrier 20, and the floating arm 12 is fixedly connected to the moving platform 21. When the cylinder body 101 of the servo electric cylinder moves, the moving platform 21 is driven to move through the connecting rod mechanism. Since the damping shock absorber 13 is located above the connecting rod 14 and its length is greater than the length of the connecting rod 14, when the cylinder body 101 moves up and down, it can transmit a realistic bumpy vibration feeling through the damping shock absorber 13. At the same time, the pulling limit of the damping shock absorber 13 by the connecting rod 14 can limit the movement amplitude and prevent the damper shock absorber from swinging too much and easily causing damage.

[0094] More 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. The initial position is the position of the floating arm 12 when no other external force is applied.

[0095] That is, when the servo motor is installed vertically, the floating arm 12 also remains in an upright state, so that the damping shock absorber 13 is connected between the floating arm 12 and the adapter 11 to form an inclined state. When the damping shock absorber 13 is in an inclined state and the floating arm 12 is in an upright state, when the cylinder body 101 moves up and down, it can ensure that the floating arm 12 simulates a more realistic up and down bumping movement. In addition, the overall structure is more compact and convenient for installation.

[0096] Reference Figure 3 to Figure 4 As shown, in some embodiments of the present invention, the adapter 11 includes a suspension flange 111 and an ear seat 112, wherein the suspension flange 111 is fixedly arranged on one side of the cylinder body 101. The ear seat 112 is connected to the suspension flange 111 through a universal joint 15, so that the ear seat 112 can rotate relative 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 seat 112 respectively.

[0097] In the related art, when the servo electric cylinder drives the moving platform 21, one of the more common problems is that the servo electric cylinder and other components are prone to mutual interference, that is, there is a mutual cylinder interference problem in the related art.

[0098] In this embodiment, the adapter 11 is mainly composed of a suspension flange 111 and an ear seat 112. The suspension flange 111 is relatively fixed to the cylinder body 101, and the ear seat 112 is connected to the suspension flange 111 through a universal joint 15. The damping shock absorber 13 and the connecting rod 14 are pivotally connected to the ear seat 112. In this way, during the motion simulation process, the rotation of the universal joint 15 can make the ear seat 112 and the suspension flange 111 rotate relative to each other when interference occurs, thereby eliminating the above-mentioned mutual cylinder interference problem. In addition, the ear seat 112 and the suspension flange 111 are connected through the universal joint 15, which can make the moving platform 21 have a certain amount of movement in the horizontal direction, thereby generating a bumpy feeling in this direction, such as shaking left and right, etc., thus further improving the simulation effect.

[0099] More specifically, the suspension flange 111 has a through hole, and the universal joint 15 includes a locking nut 151, a ball sleeve 152 and a ball shaft 153, wherein the ball sleeve 152 is embedded in the through hole; the ball shaft 153 has a first end, a second end and a ball head 1531 located between the first end and the second end, the first end is fixedly connected to the ear seat 112, and the second end is threadedly connected to the locking nut 151 after passing through the through hole, and the ball head 1531 is rotatably matched with the ball sleeve 152.

[0100] exist Figure 4 In the example, the suspension flange 111 is arranged upright, and the through hole penetrates the suspension flange 111 in the horizontal direction, and there is a step in the suspension flange 111. The ball head sleeve 152 penetrates into the through hole from one side in the horizontal direction and abuts against the step, and then the ball head sleeve 152 is pressed and fixed in the suspension flange 111 by a threaded sleeve 154 threadedly connected to the suspension flange 111. The ball head shaft 153 is penetrated in the through hole, and the ball head 1531 of the ball head shaft 153 is rotatably matched with the ball head sleeve 152. The first end of the ball head 1531 is fixedly connected to the ear seat 112, such as welding, threaded connection or integrated connection, and the second end is threadedly connected to the locking nut 151 after passing through the through hole.

[0101] In this embodiment, the universal joint 15 with the above structure is convenient and reliable to connect. The locking nut 151 and the second end of the ball head shaft 153 are locked and fixed to prevent the ball head 1531 and the ball head sleeve 152 from loosening during the simulation of bumpy motion.

[0102] More advantageously, two or more locking nuts 151 may be used, and the cooperation of the multiple locking nuts 151 with the second end of the ball shaft 153 can prevent loosening and further improve the reliability of the connection of the universal joint 15 .

[0103] Reference Figure 3 and Figures 5 and 6 As shown, in one embodiment of the present invention, the damping shock absorber 13 includes a hydraulic damper 131 and a shock absorbing spring 132, wherein the hydraulic damper 131 includes a damping cylinder 1311 and a piston rod 1312 disposed on the damping cylinder 1311 and retractable along the axis of the damping cylinder 1311. The shock absorbing spring 132 is disposed between the damping cylinder 1311 and the piston rod 1312, and is released or compressed as the piston rod 1312 retracts and retracts. The damping cylinder 1311 is pivotally connected to the one end of the floating arm 12 and one of the adapter 11, and the piston rod 1312 is pivotally connected to the one end of the floating arm 12 and the other of the adapter 11.

[0104] exist Figure 6 In the example, the lower end of the damping cylinder 1311 has a first shoulder 133, the upper end of the piston rod 1312 has a second shoulder 134, and the damping spring 132 is disposed on the hydraulic damper 131 and is located between the first shoulder 133 and the second shoulder 134. During the motion simulation, when the piston rod 1312 is compressed, the first shoulder 133 and the second shoulder 134 move relative to each other and the distance between them decreases, and the damping spring 132 between the first shoulder 133 and the second shoulder 134 can be compressed, and then the damping effect of the damping spring 132 is utilized to further improve the damping buffering effect.

[0105] Reference Figures 1 to 3 As shown, in some embodiments of the present invention, a protective cover 16 and a first telescopic cover 17 are further included. The protective cover 16 is disposed outside the servo electric cylinder; the first telescopic cover 17 is disposed outside the pushing end 102 and is telescopic with the movement of the push rod. In other words, the servo electric cylinder is encapsulated and hidden by the protective cover 16, and the moving part of the servo electric cylinder (i.e., the pushing end 102 of the push rod) is encapsulated and hidden by the first telescopic cover 17. In this way, on the one hand, the servo electric cylinder can be isolated from the external environment to prevent it from touching the user or other objects during operation, thereby improving its safety. On the other hand, it can also prevent dust or other objects from interfering with or hindering the normal operation of the servo electric cylinder, thereby ensuring its reliable and stable operation.

[0106] Exemplarily, a wire hole 161 may be provided on the shield 16 to facilitate the extraction of the power line of the servo electric cylinder.

[0107] Advantageously, a second telescopic cover 18 may also be included, wherein the second telescopic cover 18 is arranged on the outside of the connecting member, the floating arm 12, the damping shock absorber 13 and the connecting rod 14, and the second telescopic cover 18 can be extended and retracted as the floating arm 12 moves. The second telescopic cover 18 can be used to encapsulate and hide the connecting rod mechanism composed of the connecting member, the floating arm 12, the damping shock absorber 13 and the connecting rod 14 to prevent it from touching the user or other objects during movement, thereby further improving its safety. In addition, it can also prevent dust or other objects from interfering with or hindering the normal operation of the connecting rod mechanism, thereby ensuring that it operates reliably and stably.

[0108] Reference Figure 2 and Figures 5 and 6 As shown, in one embodiment of the present invention, the pushing end 102 is provided with a first fixing flange 103, and the first fixing flange 103 is suitable for connecting the fixed carrier 20. The floating arm 12 is provided with a second fixing flange 121. Preferably, the second fixing flange 121 is provided at the lower end of the floating arm 12, and the second fixing flange 121 is suitable for connecting the moving platform 21. In specific applications, the first fixing flange 103 can be connected and fixed to the fixed carrier 20, and the second fixing flange 121 can be connected and fixed to the moving platform 21, so that the installation of the motion simulation mechanism is convenient.

[0109] The vehicle driving simulation device according to the embodiment of the present invention has the motion simulation mechanism as described above.

[0110] It can be understood that the vehicle driving simulation device can also include a vehicle chassis and a movable frame, there can be multiple motion simulation mechanisms, and the multiple motion simulation mechanisms can be dispersedly arranged between the vehicle chassis and the movable frame. The pushing end 102 of the push rod in each motion simulation mechanism is connected to the vehicle chassis, and the floating arm 12 is connected to the movable frame. In this way, the multiple motion simulation mechanisms can be used to drive the movable frame to simulate bumps and other actions relative to the vehicle chassis.

[0111] The vehicle driving simulation device provided according to an embodiment of the present invention has the above-mentioned motion simulation mechanism. When the servo electric cylinder drives the motion frame to simulate the action, the power output by the servo electric cylinder is transmitted to the floating arm 12 through the shock absorber and the connecting rod 14, and then transmitted to the motion frame by the floating arm 12. In this way, more realistic bumps and other actions can be simulated to enhance the user's immersion and comfort. In addition, the shock absorption effect can be used to reduce the mechanical failure rate.
