Description

Technical Field

[0001] This invention relates to the field of driving simulation technology, and in particular to a tracked vehicle driving simulation device. Background Technology

[0002] With the rapid development of modern military, engineering and industrial manufacturing fields, tracked vehicles, as an important means of transportation and work equipment, have made the training of driving skills increasingly important.

[0003] However, traditional tracked vehicle driving training methods face numerous challenges and limitations. First, traditional real-vehicle training is costly. Tracked vehicles are large and complex mechanical devices, with high costs for purchase, maintenance, and fuel consumption. Furthermore, real-vehicle training requires significant space and human resources, further increasing training costs. Second, real-vehicle training carries certain safety risks. Due to complex road conditions and operational difficulties, tracked vehicles are prone to accidents during operation, potentially causing equipment damage and injury to the driver and surrounding personnel. To overcome the inconveniences of real-vehicle driving training, tracked vehicle driving simulators have been widely used. However, existing tracked vehicle driving simulators still fall short in terms of the overall sensory experience of driving tracked vehicles. Specifically, they lack realism in simulating the physical characteristics and operational feedback of tracked vehicle driving, making it difficult for trainees to obtain a realistic driving experience. Therefore, this application provides a tracked vehicle driving simulator to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tracked vehicle driving simulation device to solve the problem that existing tracked vehicle driving simulation equipment is insufficient in terms of the overall sensory experience of driving tracked vehicles.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A tracked vehicle driving simulation device includes a base, which is equipped with a gear-position sensing mechanism and a control arm that can swing back and forth. The back-and-forth swing of the control arm is sensed by the gear-position sensing mechanism to determine three gears: forward, stop, and reverse. A damping simulation mechanism is provided on one side of the base. The damping simulation mechanism includes a sleeve arm with an open end and a pull-out arm passing through it. The swing of the control arm pulls the pull-out arm to extend into or retract from the sleeve arm. A gear is rotatably mounted on the end of the pull-out arm that extends into the sleeve arm. A bump simulation plate is installed inside the sleeve arm. When the pull-out arm extends into or retracts from the sleeve arm, it drives the gear to roll along the bump simulation plate, generating a bumpy vibration and impact sound.

[0006] Optionally, the bump simulation plate includes a first rack arranged inside the sleeve arm, the first rack being distributed along the rolling direction of the gear, and a power component for pushing the first rack toward the gear is provided on the outer wall of the sleeve arm.

[0007] Optionally, the bump simulation plate also includes a rubber strip arranged inside the sleeve arm. The rubber strip and the first rack are symmetrically distributed around the gear. A second rack is nested on the side of the rubber strip away from the gear. A power component is provided on the outer wall of the sleeve arm to push the rubber strip and the second rack toward the gear.

[0008] Optionally, the tooth spacing of the first rack and the second rack is greater than the tooth spacing of the gear.

[0009] Optionally, a blocking block is fixed inside one end of the sleeve opening, and the blocking block is slidably sleeved with the pull-out arm.

[0010] Optionally, a resonance cavity is formed on the contact surface between the block and the pull-out arm, and a sound groove is formed on the side wall of the pull-out arm along the length direction.

[0011] Optionally, the end of the plug facing the outside of the sleeve arm is provided with a boss, and an overflow hole is obliquely opened on the side wall of the boss. The end face of the plug facing the outside of the sleeve arm is recessed and forms a conical sound amplification cavity at the opening of the sleeve arm. The overflow hole is connected to the resonance cavity and the sound amplification cavity.

[0012] Optionally, a first shaft plate and a second shaft plate are vertically fixed on the upper surface of the base. A shaft is provided near the bottom of the operating arm. The two ends of the shaft are rotatably mounted on the first shaft plate and the second shaft plate, respectively. A fixed support is hinged to the end of the sleeve arm away from the opening. A sleeve plate is hinged to the end of the pull-out arm that extends outside the sleeve arm. The other end of the sleeve plate is fitted onto the shaft, and the sleeve plate can swing synchronously with the operating arm.

[0013] Optionally, the gear sensing mechanism includes an impact member mounted on the bottom of the control arm and a sensor mounted on the first shaft plate. The swing of the control arm causes the impact member to move around the shaft. A bracket is fixed on the side of the first shaft plate away from the second shaft plate. The sensor is fixedly mounted on the bracket. There are three sensors in total. The three sensors correspond to the forward, stop, and reverse gears respectively. The three sensors are distributed along the movement trajectory of the impact member.

[0014] Optionally, the impact component includes a housing fixedly embedded at the bottom of the control arm, a steel ball movably embedded at one end of the housing facing the sensor, and a sealing bolt threaded to the other end of the housing. A spring and a steel ball are provided inside the housing. The spring force pushes the steel ball to impact the sensing end of the sensor. An adapter groove is provided on the side of the first shaft plate facing the second shaft plate. The steel ball is embedded in the adapter groove. The sensing ends of the three sensors penetrate the first shaft plate and extend into the adapter groove.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a gear sensing mechanism, the control arm is pushed to move, so that the steel ball impacts the sensing end of the sensing element corresponding to the forward, stop, and reverse gears respectively, which can realize the forward, stop, and reverse control simulation of the tracked vehicle. Two sets of this structure combination are set up to correspond to the left track control and right track control of the simulated tracked vehicle driving respectively. By simulating the control of the tracked vehicle, the dependence on the actual vehicle during training is reduced.

[0016] By setting up a damping simulation mechanism, during the simulated control of tracked vehicles by swinging the control arm, the control arm pulls the pull arm to make the arm extend or retract. At the same time, the movement of the pull arm drives the gear to roll along the bump simulation plate arranged inside the arm, generating a bumpy feeling and impact sound, while also producing a damping effect. This can simulate the real driving sensation of tracked vehicles and further reduce the reliance on actual vehicles during training.

[0017] By setting up the first rack and rubber strip, when the gear rolls unevenly along the first rack during the simulated tracked vehicle driving control process, the gear and the first rack collide to produce sound and vibration, which can simulate the real driving sensation of a tracked vehicle traveling on hard or uneven ground. When the gear rolls along the rubber strip during the simulated tracked vehicle driving control process, because the rubber strip is nested with a second rack, it can simulate the "biting" sensation of the track embedding into the ground when the tracked vehicle is traveling on muddy, swampy or other ground. The multi-mode tracked vehicle driving control simulation can provide trainees with a more realistic tactile and auditory sensory experience of tracked vehicle driving control.

[0018] Through the special structural design of the sound groove, resonance cavity, overflow hole and amplification cavity, the impact sound generated by the non-smooth rolling of the gear along the first rack, and the muffled sound generated by the collision between the gear spacer rubber strip and the second rack, can be diffused from the inside of the sleeve arm to the outside through the sound groove. When the sound reaches the resonance cavity, it resonates and is then diffused outwards by the overflow hole and sound groove in conjunction with the amplification cavity. The sound is further amplified and diffused, which enhances the realistic auditory sensation of simulating the driving control of a tracked vehicle.

[0019] This tracked vehicle driving simulation device can simulate the driving operations of tracked vehicles moving forward, stopping, and moving backward by controlling the control arm. It can also simultaneously simulate the real driving feel, hearing, and other sensory experiences of tracked vehicles in different ground environments, providing trainees with a more realistic tracked vehicle driving control experience and reducing their reliance on actual vehicles during training.

[0029] like Figures 1 to 5As shown, an embodiment of the present invention provides a tracked vehicle driving simulation device, including a base 1. The base 1 is equipped with a gear sensing mechanism and a control arm 2 that can swing back and forth. The back and forth swing of the control arm 2 is sensed by the gear sensing mechanism to determine three gears: forward, stop, and reverse. A first shaft plate 5 and a second shaft plate 6 are vertically fixed on the upper surface of the base 1. A shaft 7 is provided near the bottom of the control arm 2. The two ends of the shaft 7 are respectively rotatably mounted on the first shaft plate 5 and the second shaft plate 6 to realize the swing control of the control arm 2.

[0030] like Figures 1 to 6 As shown, the gear sensing mechanism includes an impact member 8 mounted on the bottom end of the control arm 2 and a sensing member 10 mounted on the first shaft plate 5. The sensing member 10 can be a limit switch. The swing of the control arm 2 drives the impact member 8 to move around the shaft 7. A bracket 9 is fixed on the side of the first shaft plate 5 away from the second shaft plate 6. The sensing member 10 is fixedly mounted on the bracket 9. A control box 3 is provided on the sensing member 10 and the bracket 9 to protect the sensing member 10. Furthermore, there are three sensing members 10 in total. The three sensing members 10 correspond to the forward, stop, and reverse gears, respectively. The three sensing members 10 are distributed along the movement trajectory of the impact member 8. The swing of the control arm 2 drives the impact member 8 to move around the shaft 7. The impact member 8 impacts the sensing end of the sensing member 10 corresponding to the forward, stop, and reverse gears, respectively, to realize the forward, stop, and reverse control simulation of the tracked vehicle. By controlling the tracked vehicle, the reliance on the actual vehicle during training is reduced. Specifically, the impact component 8 includes a housing 12 fixedly embedded at the bottom of the control arm 2, a steel ball 14 movably embedded in the housing 12 facing the sensing component 10, and a sealing bolt 15 threadedly connected to the other end of the housing 12. A spring 13 and a steel ball 14 are provided inside the housing 12. The sealing bolt 15 can be removed from the housing 12 to assemble the spring 13 and the steel ball 14. The spring 13 pushes the steel ball 14 to impact the sensing end of the sensing component 10 to realize gear sensing. The side of the first shaft plate 5 facing the second shaft plate 6 has an adapter groove 11. The steel ball 14 is embedded in the adapter groove 11. The sensing ends of the three sensing components 10 penetrate the first shaft plate 5 and extend into the adapter groove 11.

[0031] like Figure 1 , Figure 2 as well as Figures 7 to 11As shown, a damping simulation mechanism 4 is provided on one side of the base 1. The damping simulation mechanism 4 includes a sleeve arm 16, which has an open end and a pull-out arm 17. The operating arm 2 swings to pull the pull-out arm 17 into or out of the sleeve arm 16. Specifically, a fixed support 19 is hinged to the end of the sleeve arm 16 away from the opening, and a sleeve plate 18 is hinged to the end of the pull-out arm 17 extending outside the sleeve arm 16. The other end of the sleeve plate 18 is fitted onto the shaft 7, and the sleeve plate 18 can swing synchronously with the operating arm 2. The fixed support 19 and the base 1 are both fixed on the mounting surface. The operating arm 2 is swung to simulate the control of a tracked vehicle. During the process, the control arm 2 drives the sleeve plate 18 to swing synchronously. Utilizing the hinge between the sleeve plate 18 and the pull-out arm 17, and the hinge between the sleeve arm 16 and the fixed support 19, the swing of the sleeve plate 18 pulls the pull-out arm 17 to move out or in the sleeve arm 16. Furthermore, a gear 23 is rotatably mounted on one end of the pull-out arm 17 that extends into the sleeve arm 16. A bump simulation plate is mounted inside the sleeve arm 16. When the pull-out arm 17 extends into or out of the sleeve arm 16, it drives the gear 23 to roll along the bump simulation plate, generating a bumpy vibration and impact sound, which is used to simulate the real driving sensation of a tracked vehicle and provide trainees with a more realistic sensory experience of driving and controlling a tracked vehicle.

[0032] like Figure 1 as well as Figures 7 to 11 As shown, the bump simulation plate includes a first rack 24 arranged inside the sleeve arm 16. The first rack 24 is distributed along the rolling direction of the gear 23. A power component 20 is provided on the outer wall of the sleeve arm 16 to push the first rack 24 toward the gear 23. The tooth pitch of the first rack 24 is greater than the tooth pitch of the gear 23. When the power component 20 pushes the first rack 24 toward the gear 23 and makes contact, the gear 23 rolls along the first rack 24 during the driving control process of the tracked vehicle. The structural design of the first rack 24 having a tooth pitch greater than that of the gear 23 makes the gear 23 roll non-smoothly along the first rack 24. The collision between the gear 23 and the first rack 24 produces sound and vibration, simulating the real driving sensation of a tracked vehicle traveling on hard or uneven ground.

[0033] like Figure 1 as well as Figures 7 to 11As shown, the bump simulation plate also includes a rubber strip 25 arranged inside the sleeve arm 16. The rubber strip 25 and the first rack 24 are symmetrically distributed with the gear 23 as the center. A second rack 26 is nested on the side of the rubber strip 25 away from the gear 23. A power component 20 is provided on the outer wall of the sleeve arm 16 to push the rubber strip 25 and the second rack 26 toward the gear 23. The tooth spacing of the second rack 26 is greater than the tooth spacing of the gear 23. The power component 20 pushes the rubber strip 25 and the second rack 26 toward the gear 23 and squeezes them into contact, simulating the rolling of the gear 23 along the rubber strip 25 during the driving control of the tracked vehicle. The structure design of the second rack 26 nested on the rubber strip 25 and the tooth spacing of the second rack 26 being greater than the tooth spacing of the gear 23 makes the gear 23 roll along the rubber strip 25 to produce a "biting feeling", which can simulate the "biting feeling" of the track embedding into the ground when the tracked vehicle is driving on muddy, swampy or other ground. Among them, the power component 20 can be an automated power component such as an electric push rod available on the market, or a push-pull accessory such as a screw that can be manually controlled and is easy to maintain.

[0034] In this embodiment, the gear 23 is made of stainless steel, the first rack 24 is made of stone, ceramic or cement to simulate hard or uneven ground, and the second rack 26 is made of stainless steel. The second rack 26 is embedded in the rubber strip 25 and adopts a rubber-coated metal structure. After being squeezed and irregularly collided with the stainless steel gear 23, it is closer to the "biting feeling" of the track embedding into the ground when the track vehicle is driving on muddy, swamp or other ground.

[0035] like Figure 1 as well as Figures 7 to 11As shown, a blocking block 21 is fixed inside one end of the opening of the sleeve arm 16. The blocking block 21 is slidably sleeved with the pull-out arm 17 to guide and limit the extension or withdrawal of the pull-out arm 17 into the sleeve arm 16. Furthermore, a resonance cavity 27 is formed on the contact surface between the blocking block 21 and the pull-out arm 17. A sound groove 22 is formed along the length direction on the side wall of the pull-out arm 17. A boss 28 is provided on the end of the blocking block 21 facing the outside of the sleeve arm 16. An overflow hole 29 is obliquely formed on the side wall of the boss 28. The end face of the blocking block 21 facing the outside of the sleeve arm 16 is recessed and forms a conical amplification cavity 30 at the opening of the sleeve arm 16. The conical amplification cavity 30 has a sound amplification effect. The overflow hole 29 connects the resonance cavity 27 and the amplification cavity 30. The gear 23... The impact sound generated by the non-smooth rolling of the first rack 24, and the muffled sound generated by the collision between the rubber strip 25 of the gear 23 and the second rack 26, can spread outward from the inside of the sleeve arm 16 through the sound groove 22. When the sound reaches the resonance cavity 27, it resonates and then spreads outward from the sleeve arm 16 through the overflow hole 29 and the sound groove 22 in conjunction with the amplification cavity 30. The sound is strengthened and spread through resonance, which enhances the real auditory senses of simulating the driving control of tracked vehicles and provides trainees with a more realistic experience of driving control of tracked vehicles.

[0036] The working principle of the technical solution provided by this invention is as follows: In use, the two sets of this structure are respectively used to simulate the left track control and right track control of the tracked vehicle driving. The base 1 and the fixed support 19 are fixed together on the mounting surface. Specifically, pushing the control arm 2 to swing causes the impact piece 8 to align with the sensor 10 corresponding to the forward gear. The spring 13 pushes the steel ball 14 to strike the sensing end of the sensor 10 corresponding to the forward gear. The sensor 10 corresponding to the forward gear outputs a signal to make a forward sensing judgment. As a result, the control arm 2 is pushed to move, so that the steel ball 14 strikes the sensing end of the sensor 10 corresponding to the forward, stop, and reverse gears respectively. This can realize the simulation of the forward, stop, and reverse control of the tracked vehicle. By simulating the control of the tracked vehicle, the dependence on the actual vehicle during training is reduced.

[0037] Furthermore, during the simulated control of the tracked vehicle by manipulating the swing of the control arm 2, the control arm 2 drives the sleeve plate 18 to swing synchronously. Utilizing the hinge between the sleeve plate 18 and the pull-out arm 17, and the hinge between the sleeve arm 16 and the fixed support 19, the swing of the sleeve plate 18 pulls the pull-out arm 17 to move out or in the sleeve arm 16. At the same time, the movement of the pull-out arm 17 drives the gear 23 to roll along the bump simulation plate arranged inside the sleeve arm 16, generating a bumpy vibration and impact sound, while also producing a damping effect, simulating the real driving sensation of a tracked vehicle, and further reducing the reliance on actual vehicles during training. Specifically, when the power component 20 pushes the first rack 24 close to and into contact with the gear 23, simulating the rolling of the gear 23 along the first rack 24 during the driving control of a tracked vehicle, the gear 23 can roll non-smoothly along the first rack 24 because the tooth spacing of the first rack 24 is larger than that of the gear 23. The collision between the gear 23 and the first rack 24 produces sound and vibration, which can simulate the real driving sensation of a tracked vehicle traveling on hard or uneven ground. When the power component 20 pushes the rubber strip 25 and the second rack 26... When the gear 23 is brought close to and pressed into contact, the gear 23 rolls along the rubber strip 25 during the simulated tracked vehicle driving control process. Since the second rack 26 is nested on the rubber strip 25 and the tooth spacing of the second rack 26 is greater than the tooth spacing of the gear 23, the gear 23 rolls along the rubber strip 25, which can simulate the "biting" feeling of the track embedding into the ground when the tracked vehicle is driving on muddy, swampy or other ground. The multi-mode tracked vehicle driving control simulation can provide trainees with a more realistic tactile and auditory sensory experience of tracked vehicle driving control.

[0038] Furthermore, through the special structural design of the sound groove 22, resonance cavity 27, overflow hole 29, and amplification cavity 30, the impact sound generated by the non-smooth rolling of the gear 23 along the first rack 24, and the muffled sound generated by the collision between the gear 23 and the second rack 26 through the rubber strip 25, can diffuse outward from inside the sleeve arm 16 through the sound groove 22. When the sound reaches the resonance cavity 27, it resonates and then diffuses outward from the sleeve arm 16 through the overflow hole 29 and the sound groove 22 in conjunction with the amplification cavity 30. The sound is further amplified and diffused, thus enhancing the realistic auditory perception of simulating the driving control of a tracked vehicle.

[0039] In summary, this tracked vehicle driving simulation device can simulate the driving operations of a tracked vehicle moving forward, stopping, and moving backward by controlling the control arm 2. It can also simultaneously simulate the real driving feel, hearing, and other sensory experiences of a tracked vehicle in different ground environments, providing trainees with a more realistic tracked vehicle driving control experience and reducing their reliance on actual vehicles during training.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
