Description

Technical Field

[0001] This utility model relates to a simulation training device, specifically a manual transmission separation device for armored vehicle simulation training, belonging to the technical field of military training equipment. Background Technology

[0002] The real vehicle's transfer case control mechanism is used to control the forward and reverse rotation of the water propeller to change the vehicle's direction of motion. Its structure and transmission system are relatively complex and cannot be applied to simulation training equipment. The manual transmission disengagement device in the simulator is designed to mimic the real vehicle's transfer case control mechanism, requiring that its appearance, operation method, and operating force feel be basically consistent with the real vehicle's transfer case control mechanism.

[0003] However, the rotation angle and operating force of the traditional simulator transmission manual separation device are quite different from those of the actual vehicle. In addition, the structure is easily damaged, prone to jamming, and has poor reliability, which cannot guarantee that the troops can carry out long-term, high-frequency operation training.

[0004] In view of the above, in order to overcome the above technical problems, this utility model designs a manual transmission separation device for armored vehicle simulation training, which solves the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to simulate the switching between different gear positions by rotating the shaft assembly in multiple directions through the lever assembly, thereby causing the steel ball inside the damping assembly to move.

[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution:

[0007] The present invention provides a manual transmission separation device for armored vehicle simulation training, comprising a housing, a lever assembly, and a support base. The lever assembly is installed in the housing, and a handle ball is provided at the upper end of the lever assembly. The support base is used to provide support force. The gear plate provided on the housing cooperates with the lever assembly to simulate the forward gear (H gear), neutral gear (N gear), and reverse gear (R gear) of a vehicle, providing users with intuitive gear switching guidance during training.

[0008] The upper end of the lever assembly is equipped with a handle ball for easy gripping and control, while the lower end connects to other components via a pivot assembly. The lever's operational flexibility and force feedback design are consistent with the feel of operating a real vehicle, allowing trainees to experience realistic gear shifting during training. The precise fit between the lever and the gear shift slot further enhances operational stability.

[0009] It also includes a shaft assembly, a damping assembly, and a self-aligning assembly. The shaft assembly is installed inside the housing, and the lever assembly and damping assembly are connected to the shaft assembly. By rotating the shaft assembly, the lever assembly and the support base slide against each other. The shaft assembly, as the transmission core, transmits the rotational motion of the lever to other components. Both ends of the shaft are fixed to the housing by high-precision self-aligning ball bearings, ensuring the rotational stability and long-term durability of the shaft.

[0010] A damping component is provided between the shaft assembly and the support base, and the damping component is used to provide damping force when the shaft assembly and the support base slide against each other.

[0011] During lever operation, the pivot drive connects to the damping assembly, providing real physical feedback during gear shifting. The pivot assembly not only transmits force but also, in conjunction with the self-aligning assembly, enables precise lever resetting.

[0012] The upper end of the lever assembly is provided with a self-aligning assembly, which is used to reset the rotation of the lever assembly.

[0013] The damping assembly is a component that simulates the feel of shifting gears. It consists of an extension arm, a damping spring, a steel ball, and a damping plate. The extension arm is mounted on the shaft assembly and is perpendicular to the axis of the shaft assembly. The extension arm contains a damping spring, and a steel ball is located at the front end of the damping spring. The damping plate is mounted on a support base. The damping plate has multiple damping grooves, and the steel ball contacts the damping grooves.

[0014] The movement of a steel ball on a damping plate and its interaction with the grooves create the damping sensation and jolt feedback during gear shifts. Different gear positions are limited by grooves on the damping plate, with protrusions between each position further enhancing the realism of the shifting operation. During gear shifting, the damping assembly, through the interaction of a preloaded spring and the steel ball with the grooves, simulates the operating force and resistance felt during gear shifting in a real vehicle, allowing trainees to accurately experience the mechanical characteristics of forward, reverse, and neutral shifting.

[0015] The damping plate is provided with a sensing component behind each damping groove, and the sensing component is used to detect the position of the steel ball in the multiple damping grooves.

[0016] The sensing assembly includes a sensing tube, a tube support, and a light shield. The tube support supports the sensing tube, which consists of two parts: one end emits a signal, and the other end receives a signal. The front end of the sensing tube is precisely aligned with the center of rotation of the extended arm, ensuring that the tube can accurately capture the moment when the signal is blocked by the light shield during each gear shift, thereby determining whether the steel ball is located in the specific gear groove.

[0017] The light-shielding plate is mounted on the extension arm and rotates with the extension arm. The light-shielding plate is used to isolate and disconnect the signal transmission and reception of the sensing tube. The front end of the sensing tube points to the center of rotation of the extension arm.

[0018] During gear shifting, the light-shielding plate interacts with the sensor pair, detecting the actual position of the steel ball by blocking the signal transmission and reception path. When the light-shielding plate passes through the sensor pair, it blocks signal transmission or reception, causing a change in electrical signal interruption, reflecting the gear position shift. The rotational precision of the light-shielding plate is synchronized with the movement of the extension arm, ensuring accurate acquisition of gear information.

[0019] The self-aligning assembly includes a flat shaft and a return spring. The flat shaft is vertically mounted on the shaft assembly. The upper end of the flat shaft is connected to the lever assembly via the return spring. The extension and retraction direction of the return spring is parallel to the axial direction of the shaft assembly. The lower end of the lever assembly is rotatably mounted on the shaft assembly.

[0020] The design of the self-aligning assembly allows the lever assembly to maintain a reasonable return motion during simulated training, enhancing the realism of the control. The elasticity and damping provided by the return spring during operation also help the operator obtain an operating experience similar to the transfer case control mechanism in a real vehicle, improving the realism of the simulator.

[0021] The rotating bearing is a self-aligning ball bearing. The self-aligning ball bearing supports the shaft assembly and allows it to rotate freely during operation. Since the shaft assembly connects the lever assembly and the damping assembly, the self-aligning ball bearing ensures that these components operate smoothly and steadily, especially during high-frequency training use, preventing excessive friction or jamming.

[0022] A stop plate is installed at the upper end of the housing, and a stop groove is formed on the stop plate to accommodate the lever assembly. Through the design of the stop groove, the lever assembly can perform precise and smooth gear shifting during simulated training, while avoiding jamming problems caused by improper groove design, thus ensuring the reliability and efficiency of the training equipment.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. The operation method, rotation angle and operating force achieved by the combination of the hand lever assembly and damping assembly of this utility model are basically the same as those of the actual vehicle transfer case control mechanism. It can completely replace the actual transfer case control mechanism for training the forward, reverse and neutral shifting operations during water driving, greatly improving the realism of the simulation training.

[0025] 2. This utility model sets induction pairs on the damping plate, and then uses the light shield that follows the rotation of the extension arm to trigger the induction pairs at different gear grooves, so that the gear information in the simulation training can be transmitted to the computer through electrical signals, thereby realizing the intelligentization of training data.

[0042] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] The manual transmission separation device for armored vehicle simulation training according to an embodiment of the present invention includes a housing 1, a lever assembly 2, and a support base 3. The lever assembly 2 is installed inside the housing 1, and a handle ball 21 is provided at the upper end of the lever assembly 2. It also includes a rotating shaft assembly 4, a damping assembly 5, and a self-aligning assembly 6. The rotating shaft assembly 4 is installed inside the housing 1, and the lever assembly 2 and the damping assembly 5 are connected to the rotating shaft assembly 4.

[0044] Both ends of the rotating shaft assembly 4 are installed in the housing 1 through rotating bearings 41. The rotating bearings 41 are specifically self-aligning ball bearings. The self-aligning ball bearings are embedded in the bearing chambers in the housing 1. The self-aligning ball bearings are provided with end caps on the outside of the self-aligning ball bearings. The end caps are connected to the housing 1 by bolts to press the self-aligning ball bearings tightly. A damping component is provided between the rotating shaft assembly 4 and the support base 3.

[0045] The damping assembly includes an extension arm 51, a damping spring 52, a steel ball 53, and a damping plate 54. The extension arm 51 is mounted on the rotating shaft assembly 4 and is perpendicular to the axial direction of the rotating shaft assembly 4. The extension arm 51 is provided with a damping spring 52, and a steel ball 53 is provided at the front end of the damping spring 52. The damping plate 54 is provided on the support base 3. The damping plate 54 has three damping grooves 55, and the steel ball 53 contacts the damping grooves 55.

[0046] The damping plate 54 has three damping grooves 55: the upper one, the middle one, and the lower one. The upper damping groove 55 is used to simulate the limiting and force feel of the H gear position, the middle damping groove 55 is used to simulate the limiting and force feel of the N gear position, and the lower damping groove 55 is used to simulate the limiting and force feel of the R gear position. There is a protrusion between every two limiting grooves. When shifting gears, the steel ball 53 will move across the protrusion, at which time there will be a noticeable damping feel and a jolt.

[0047] In this embodiment, a self-aligning ball bearing is installed at the end of the extended arm 51 of the rotating shaft assembly 4, and the bearing housing is connected to the self-aligning ball bearing; the damping spring 52 and the steel ball 53 are installed into the mounting holes in the extended arm 51 of the rotating shaft assembly 4, the groove on the damping plate 54 is used to press the steel ball 53 against the ground, the bottom of the damping plate 54 is fixed with bolts, the steel ball 53 is pushed into the hole a certain distance, so that the damping spring 52 has a certain preload, and then the bottom bolt of the damping plate 54 is tightened. When the steel ball 53 moves, damping is generated between it and the damping groove 55, forming the operating force of the lever assembly 2. The damping magnitude can be adjusted by changing the relative distance of the damping plate 54.

[0048] The sensing assembly 56 includes a sensing tube 561, a tube support 562, and a light shield 563. The tube support 562 supports the sensing tube 561. The light shield 563 is mounted on the extension arm 51 and rotates with the extension arm 51. The light shield 563 is used to isolate and disconnect the signal transmission and reception of the sensing tube 561. The front end of the sensing tube 561 points towards the center of rotation of the extension arm 51.

[0049] The tube support 562 is connected to the tube by a thread, and the tube support 562 is connected to the damping plate 54 by a thread; the light shield 563 is connected to the extension arm 51 of the rotating shaft assembly 4 by a thread. The extension distance of the light shield 563 is adjusted so that it does not interfere when passing through the tube. Finally, the cover is connected to the damping plate 54 with screws.

[0050] The self-aligning assembly 6 includes a flat shaft 61 and a return spring 62. The flat shaft 61 is vertically mounted on the rotating shaft assembly 4. The upper end of the flat shaft 61 is connected to the lever assembly 2 via the return spring 62. In this embodiment, the flat shaft 61 on the rotating shaft assembly 4 needs to be inserted into the fork at the lower end of the lever assembly 2, aligned with the mounting hole, and connected by bolts. Because there is a fitting clearance between the fork and the flat shaft 61, the two can rotate freely relative to each other after connection. The extension and retraction direction of the return spring 62 is parallel to the axial direction of the rotating shaft assembly 4, and the lower end of the lever assembly 2 is rotatably mounted on the rotating shaft assembly 4.

[0051] After the shaft assembly 4 is connected to the lever assembly 2, the whole assembly extends into the box 1. The shaft end of the shaft assembly 4 is inserted into the inner hole of the self-aligning ball bearing and installed in place so that the shaft shoulder is close to the end face of the inner ring of the self-aligning ball bearing.

[0052] A stop plate 11 is installed on the upper end of the housing 1. The stop plate 11 has a stop groove 12 for accommodating the lever assembly 2. The stop plate 11 is threaded to the housing 1; the handle ball 21 is threaded to the lever assembly 2; one end of the return spring 62 is hung on the rotating shaft assembly 4, and the other end is hung on the lever assembly 2. Under the action of the spring tension, the lever assembly 2 will always be in close contact with the stop tooth groove on the stop plate 11.

[0053] The gear shift plate 11 has three gear slots 12: H, N, and R, representing forward, neutral, and reverse gears respectively when driving the vehicle on water. The lever assembly 2 can slide into each gear slot 12 to simulate the gear shifting operation of the device.

[0054] When the lever assembly 2 is in the neutral (N) position, the hand crank can swing freely left and right (the lever assembly 2 rotates around its bottom bolt), simulating a certain amount of operating force. After the external force is removed, the lever assembly 2 automatically returns to the neutral (N) position slot 12 due to the tension of the return spring 62. At this time, the steel ball 53 is in the damping groove 55 in the middle of the damping plate 54, remaining stationary under the elastic force of the damping spring 52.

[0055] When the lever assembly 2 slides forward from N to H, it drives the extension arm 51 of the rotating shaft assembly 4 to rotate counterclockwise, pushing the steel ball 53 upward. As the steel ball 53 passes the protrusion, it retracts into the hole, increasing the elastic force of the damping spring 52 inside the hole. After the steel ball 53 passes the protrusion, the spring pressure of the damping spring 52 presses it into the upper damping groove 55, completing the shift from N to H. This process provides a noticeable damping sensation and a jolt, simulating the shifting force and operation.

[0056] The light shield 563 rotates along with the extension arm 51 of the rotating shaft assembly 4, rotating from the middle position to the tube at the upper damping groove 55, with its head inserted between the two ends of the tube. Signal acquisition is accomplished through the interaction between the light shield 563 and the tube. A high-quality infrared tube device is selected, with one end of the tube emitting infrared light and the other end receiving it. When the head of the light shield 563 is inserted between the two ends of the tube, the transmission / reception is interrupted, generating a corresponding electrical signal. The signal is processed and transmitted to the computer, and the computer software simulates the normal forward movement of the vehicle on water.

[0057] When the lever assembly 2 is moved from neutral (N) to reverse (R), the working process is the same as above, but the direction of movement is reversed. The steel ball 53 moves from the middle damping groove 55 into the lower damping groove 55. The head of the light shield 563 is inserted between the two ends of the tube in the lower groove, generating a corresponding electrical signal. The signal is processed and transmitted to the computer. The computer software simulates reverse gear, which can remove weeds, fishing nets, etc. tangled on the water propeller.
