[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0034] This utility model is a gear adjustment mechanism for a driving simulator. Figure 1-7, including a frame 1, a fixed shaft 2, a stop rod 3, a clamping block 4, a pin 5 and a driving device 6. The bottom end of the frame 1 is provided with a gear slot 7, the stop rod 3 is rotatably set in the frame 1 through the fixed shaft 2, one end of the stop rod 3 extends into the gear slot 7, and the end of the stop rod 3 extending from the bottom end of the frame 1 reciprocates between the various gears of the gear slot 7, the clamping block 4 is slidingly set at the bottom end of the frame 1, one end of the clamping block 4 is provided with a movable slot 8, the stop rod 3 passes through the clamping block 4 through the movable slot 8 and is movably connected to the clamping block 4, the other end of the clamping block 4 is also provided with a card hole 9, the fixed end of the driving device 6 is set on the frame 1, one end of the pin 5 is provided with a buffer device 61, the driving end of the driving device 6 is connected to the pin 5 through the buffer device 61, and in actual use, the driving device 6 and the automobile model The clutch in the simulator is connected in communication, and the driving device 6 is controlled by the clutch. During use, when it is necessary to step on the clutch to engage the gear, the clutch sends a signal to the driving device 6. At this time, the driving device 6 drives the ejector pin 5 to move away from the clamping block 4, releasing the restriction of the ejector pin 5 on the clamping block 4, so that the trainee can operate the gear lever 3 to change the gear. When the gear lever 3 moves to the gear position in the gear slot 7, the gear lever 3 pushes the clamping block 4 to slide, so that the clamping hole 9 corresponding to the gear position on the clamping block 4 is aligned with the ejector pin 5. At this time, the trainee releases the clutch, and the clutch drives the ejector pin 5 to pass through the clamping hole 9 again through the driving device 6, thereby completing the gear engagement action. The gear simulator and the clutch are linked together through the clamping block 4, the ejector pin 5 and the driving device 6, which greatly enhances the user experience of the gear simulator.

[0035] Secondly, as is well known, the electric drive device 6 is a common drive device 6. During use, the drive device 6 controls the operation of the motor according to an external pulse signal, thereby driving the driving end of the drive device 6 to achieve telescopic movement. Therefore, when the card hole 9 on the clamping block 4 is not aligned with the ejector 5 (that is, the blocking rod 3 is not accurately moved to the target gear position), the drive device 6 drives the ejector 5 to move, which may damage the ejector 5 or the clamping block 4. Therefore, in order to avoid the above situation, in this embodiment, a buffer device 61 is provided at one end of the ejector 5, and the driving end of the drive device 6 is connected to the buffer device. 61 is connected to the ejector 5, and the stroke of the ejector 5 is divided into two states by the buffer device 61, namely, the normal movement state of the ejector 5 and the state in which the ejector 5 abuts the clamping block 4. When the ejector 5 is in the normal movement state, the driving device 6 drives the ejector 5 to move, and the relative position between the driving end of the driving device 6 and the ejector 5 does not change. When the ejector 5 abuts the clamping block 4, the ejector 5 contacts the clamping block 4, and the driving end of the driving device 6 continues to move. At this time, the driving end of the driving device 6 is relatively displaced with the ejector 5 through the buffer device 61, thereby preventing the ejector 5 from damaging the clamping block 4.

[0036] Specifically, the buffer device 61 includes a buffer block 63, a fixed rod 64 and a first spring member 62. The fixed rod 64 is arranged on the frame 1. The buffer block 63 is slidably arranged on the fixed rod 64. The ejector pin 5 is arranged on the upper end surface of the buffer block 63. The lower end of the buffer block 63 is provided with a buffer groove 65. The driving end of the driving device 6 is arranged in the buffer groove 65 and is slidably connected to the buffer block 63. The first spring member 62 is sleeved on the fixed rod 64. One end of the first spring member 62 is connected to the fixed rod 64, and the other end is against the lower end of the buffer block 63. During the extension of the driving end of the driving device 6, the buffer block 63 moves toward the clamping block 4 under the action of the first spring, and at this time the relative motion relationship between the buffer block 63 and the driving end of the driving device 6 remains unchanged. When the ejector pin 5 contacts the clamping block 4, the driving end of the driving device 6 moves, and at this time the driving end placed in the buffer groove 65 moves from the bottom end of the buffer groove 65 to the top end of the buffer groove 65. During this process, the driving end of the driving device 6 does not apply pressure to the buffer block 63, thereby preventing the ejector pin 5 from damaging the clamping block 4.

[0037] It should be noted that, when the driving device 6 drives the ejector 5 to move via the buffer device 61 , the driving end of the driving device 6 is always placed in the buffer groove 65 and is slidably connected to the buffer block 63 .

[0038] In this embodiment, a fixing bolt 10 is also included, and a sliding groove 11 is provided on the clamping block 4. The fixing bolt 10 passes through the clamping block 4 through the sliding groove 11 and is connected to the frame 1. The fixing bolt 10 can not only make the clamping block 4 slidably set on the frame 1, but also, under the joint action of the fixing bolt 10 and the sliding groove 11, the movement trajectory of the clamping block 4 can be limited (that is, when the blocking rod 3 pushes the clamping block 4 to slide, the clamping block 4 only slides along a specific trajectory), which greatly increases the stability of the clamping block 4 during movement.

[0039] In this embodiment, a sliding pressure plate 12 is also included. The sliding pressure plate 12 has a "J"-shaped structure. The sliding pressure plate 12 is arranged at the bottom end of the frame 1 and forms a sliding channel with the frame 1. The end of the clamping block 4 away from the blocking rod 3 is slidably arranged in the sliding channel, further increasing the stability of the clamping block 4 during movement.

[0040] In this embodiment, the fixed rotating shaft 2 includes a rotating seat 21, a first connecting shaft 22 and a second connecting shaft 23. The rotating seat 21 can be rotatably set in the frame 1 through the first connecting shaft 22. The center of the rotating seat 21 is provided with a through groove 24, and the second connecting shaft 23 is set in the through groove 24, and the first connecting shaft 22 and the second connecting shaft 23 are set vertically. The gear rod 3 is rotatably set on the second connecting shaft 23. The gear rod 3 can be fixed in the frame 1 by the first connecting shaft 22 and the second connecting shaft 23, ensuring that the gear rod 3 can swing in any direction of front, back, left and right in the gear slot 7 (that is, the end of the gear rod 3 extending into the gear slot 7 can reciprocate between the various gears in the gear slot 7).

[0041] In this embodiment, a damper 13 is also included. The damper 13 is arranged on the side wall of the rotating seat 21. When the gear lever 3 moves to the gear position in the gear slot 7, the damper 13 hinders the movement of the gear lever 3, so that the trainee feels more realistic when practicing shifting gears.

[0042] Specifically, the damper 13 includes a snap fit 131 and an elastic ejector pin 132. The snap fit 131 is arranged on the outer wall of the rotating seat 21. The side of the snap fit 131 away from the rotating seat 21 is arc-shaped, and the arc is arranged with the axis of the second connecting shaft 23 as the center. The side of the snap fit 131 away from the rotating seat 21 is also provided with multiple groups of slots 133. The multiple groups of slots 133 are distributed along the circumference of the arc. The elastic ejector pin 132 is arranged on the frame 1. When the gear lever 3 moves to the gear position in the gear slot 7, the elastic ejector pin 132 is placed in the slot 133 and engages with the snap fit 131.

[0043] In this embodiment, a reset device 14 is further provided for driving the gear lever to automatically return to a vertical state, that is, the gear lever can automatically return to the neutral position through the reset device 14, thereby making the gear simulator more realistic. The reset device 14 includes a base 141, a slide bar 142 and a slider 143. The base 141 is provided with the bottom end of the rotating seat 21, the slide bar 142 is provided on the base 141, and the slide bar 142 is provided perpendicular to the second connecting shaft 23. The slider 143 is slidably provided on the slide bar 142, and the gear lever passes through the slider 1 43, and is movably connected to the slider 143, and a second spring member 144 is provided on both sides of the slider 143, and the two ends of the second spring member 144 are respectively connected to the base 141 and the slider 143. During use, when the blocking rod 3 is changed, the blocking rod pushes the slider 143 to slide along the slide rod 142, thereby causing the second springs on both sides of the slider 143 to be stretched or compressed. When the blocking rod loses the external force, the slider 143 drives the blocking rod to move under the action of the second spring, thereby allowing the blocking rod to return to the neutral position.

[0044] In this embodiment, the reset device 14 further includes a ball shaft 145 , which is disposed on the blocking rod 3 . The blocking rod 3 is movably connected to the slider 143 via the ball shaft 145 , thereby making the connection between the blocking rod 3 and the slider 143 more flexible.

[0045] The above disclosures are only a few specific embodiments of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
