Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a gear shift return structure in a gear shift simulator. Background Technology

[0002] In automotive driving simulation training systems, the gear shift simulator is a key human-machine interface device for reproducing the realistic driving experience. Traditional simulator gear shift return mechanisms often adopt the multi-spring assembly scheme used in real vehicles, providing return force through the compression and deformation of the springs. However, this structure reveals significant shortcomings in simulator applications: First, simulators are used far more frequently than real vehicles, and the spring components are prone to fatigue failure under frequent operation, leading to a decrease in the return force and affecting training effectiveness. Second, the uneven force distribution in the multi-spring structure makes the gear lever's return trajectory inaccurate, failing to accurately simulate the gear shifting feel of a real vehicle. Furthermore, the complex spring components increase the simulator's manufacturing cost and maintenance difficulty. As driving simulation training increasingly demands realism and equipment reliability, the existing return structure has become a bottleneck restricting simulator performance improvement.

[0003] Therefore, there is an urgent need to develop a gear return structure specifically designed for driving simulators, featuring high reliability, precise return characteristics, and long service life. Utility Model Content

[0004] To address the aforementioned issues, this application provides a gear shift return structure in a gear shift simulator. Through the coordinated design of a single torsion spring and a limiting groove, it accurately replicates the operational force and return characteristics of a real vehicle's gear shift, improving the simulation's realism and operational accuracy. The technical solution is as follows: This application provides a gear shift return structure in a gear shift simulator, including a gear shift support block, a torsion spring, and a limiting frame. The bottom of the gear shift support block has protrusions and protrusions symmetrically arranged around the gear shift lever. The torsion spring includes a spring body and two straight arms. The spring body is sleeved on the protrusions and fixed by fasteners. The two straight arms elastically clamp the gear shift lever from both sides. The limiting frame is fixed to the bottom of the gear shift support block, forming a limiting groove between itself and the bottom surface of the gear shift support block. The free ends of the two straight arms are respectively located within the limiting groove and abut against both sides of the protrusions. When the gear shift lever swings, it drives the straight arms to move within the limiting groove. The elastic force of the torsion spring provides a return force to the straight arms, thereby driving the gear shift lever back to its initial position.

[0005] For example, in the gear shift simulator provided in one embodiment, the distance between the two straight arms and the width of the protrusion are matched with the diameter of the gear lever, forming a tight elastic constraint on the gear lever.

[0006] For example, in the gear shift simulator provided in one embodiment, the gear shift return structure has a U-shaped limit frame with its two sides fixedly connected to the sidewall of the gear shift support block, and its middle part closely abutting against the protrusion, dividing the limit groove into two independent guide grooves on the left and right.

[0007] For example, in the gear shifting simulator provided in one embodiment, the two straight arms are respectively accommodated in the two guide grooves and move along the length direction of the guide grooves.

[0008] For example, in the gear shift simulator provided in one embodiment, the length of the limiting groove is adapted to the swing stroke of the gear lever to limit the range of movement of the straight arm and ensure the accuracy of the return-to-center action.

[0009] For example, in the gear shifting simulator provided in one embodiment, the height of the limiting groove is adapted to the height of the protrusion to limit the vertical displacement of the straight arm and prevent the straight arm from coming out of the limiting groove.

[0010] For example, in the gear shift simulator provided in one embodiment, the convex post and the convex block are located at the two sides of the bottom surface of the gear support block, and are arranged symmetrically with the gear lever as the central axis.

[0011] For example, in the gear shift simulator provided in one embodiment, the gear return structure is a fastener that is a nut with a diameter greater than the outer diameter of the protrusion, used to axially limit the spring body.

[0012] For example, in the gear shift simulator provided in one embodiment, the gear shift support block is wrapped with a gear shift cover, and the gear shift lever passes through the gear shift support block and the gear shift limit plate in sequence.

[0013] For example, in the gear shift simulator provided in one embodiment, the torsion spring applies a continuous elastic clamping force to the gear lever through its two straight arms, stores elastic potential energy when the gear lever deviates from its initial position, and drives the gear lever to automatically return to the center position when released.

[0014] This application provides a gear shift return structure in a gear shift simulator, which offers the following significant advantages for the specific needs of driving simulators: Enhanced simulation realism and operational precision: Through the coordinated design of a single torsion spring and a limiting groove, the operating force and return characteristics of gear shifting in a real vehicle are accurately reproduced, allowing trainees to obtain tactile feedback that is highly consistent with real vehicle operation during simulated training, greatly improving the training effect.

[0015] Durability and maintainability optimization: In view of the high-frequency use of the simulator, an integral torsion spring is used instead of a multi-spring assembly, which significantly reduces the number of moving parts and simplifies assembly.

[0016] Motion control precision assurance: The precise guiding mechanism of the limit groove ensures that the stop lever maintains a precise return position. This eliminates the problem of return position drift caused by component wear, ensuring consistent training quality.

[0017] Enhanced realism of force feedback: Based on a symmetrically arranged torque transmission system, a perfect balance of left and right return forces is achieved, and the damping characteristics of the return process are precisely controlled. Attached Figure Description

Detailed Implementation

[0020] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] like Figure 1-3As shown, this application provides a gear shift return structure in a gear shift simulator, including a gear shift support block 10, a torsion spring 20, and a limiting frame 30. The bottom of the gear shift support block 10 is provided with protruding posts 11 and protrusions 12 symmetrically arranged around the gear shift lever 40. The torsion spring 20 includes a spring body 21 and two straight arms 22. The spring body 21 is sleeved on the protruding post 11 and limited and fixed by fasteners 13. The two straight arms 22 elastically clamp the gear shift lever 40 from both sides. The limiting frame 30 is fixed to the bottom of the gear support block 10, forming a limiting groove 31 between the frame and the bottom surface of the gear support block 10. The free ends of the two straight arms 22 are respectively located in the limiting groove 31 and abut against the two sides of the protrusion 12. When the gear lever 40 swings, it drives the straight arms 22 to move in the limiting groove 31. The elastic force of the torsion spring 20 provides a restoring force to the straight arms 22, thereby driving the gear lever 40 back to the initial position.

[0022] The gear support block 10 is externally covered by a gear cover 50, and the gear lever 40 passes through the gear support block 10 and the gear limiting plate 60 in sequence.

[0023] The gear shift simulator of this application features a gear return structure. This structure utilizes symmetrical protrusions 11 and 12 centered on the gear shift lever 40. The two straight arms 22 of the torsion spring 20 are positioned within limiting grooves 31, abutting against the sides of the protrusions 12. This creates a mechanical return system driven by the torsion spring 20 and guided by the limiting grooves 31. When the gear shift lever 40 swings, it moves the straight arms 22 within the limiting grooves 31, compressing the spring. The stored elastic potential energy of the spring serves as the return power source, enabling automatic and rapid reset of the gear shift lever 40 after deviation. This replaces the traditional complex multi-spring assembly, simplifying the structure.

[0024] For example, in the gear shift simulator provided in one embodiment, the gear return structure, such as Figure 2-3 As shown, the distance between the two straight arms 22 and the width of the protrusion 12 are matched with the diameter of the stop lever 40, forming a tight elastic constraint on the stop lever 40.

[0025] According to the above embodiment, by matching the distance between the two straight arms 22 and the width of the protrusion 12 with the diameter of the gear lever 40, a stable surface contact rather than point contact is formed between the gear lever 40 and the straight arms 22. This tight elastic constraint ensures the uniformity and reliability of torque transmission, avoids back-alignment lag or vibration caused by gaps, and effectively suppresses abnormal vibration of the gear lever 40 during driving through continuous clamping force.

[0026] For example, in the gear shift simulator provided in one embodiment, the gear return structure, such as Figure 2-3As shown, the limiting frame 30 has a U-shaped structure, with its two sides fixedly connected to the side wall of the stop support block 10, and its middle part closely abutting against the protrusion 12, dividing the limiting groove 31 into two independent guide grooves on the left and right.

[0027] According to the above embodiment, by using a U-shaped limiting frame 30 that is closely abutting against the protrusion 12, the limiting groove 31 is divided into two independent guide grooves. This provides each straight arm 22 with an independent and controlled motion track. This separation design prevents the two straight arms 22 from interfering with each other during movement, ensuring the symmetry and directional stability of the return force. At the same time, the U-shaped structure itself enhances the structural rigidity of the bottom of the entire support block.

[0028] For example, in the gear shift simulator provided in one embodiment, the gear return structure, such as Figure 2-3 As shown, the two straight arms 22 are respectively accommodated in the two guide grooves and move along the length direction of the guide grooves.

[0029] According to the above embodiment, by accommodating the two straight arms 22 in two independent guide slots, precise guidance and distribution of the return force are achieved. Each straight arm 22 moves within its own slot, avoiding the intersection and cancellation of force lines, so that the stop lever 40 can obtain a uniform return torque whether it swings to the left or right, thus improving the smoothness and accuracy of the return action.

[0030] For example, in the gear shift simulator provided in one embodiment, the gear return structure, such as Figure 2-3 As shown, the length of the limiting groove 31 is adapted to the swing stroke of the stop lever 40, which is used to limit the movement range of the straight arm 22 and ensure the accuracy of the return action.

[0031] According to the above embodiment, by precisely matching the length of the limiting groove 31 with the swing stroke of the shift lever 40, a clear physical boundary is set for the return-to-center action, preventing the two straight arms 22 from falling out of the guide groove. This design ensures that the shift lever 40 has sufficient range of motion to complete the shifting operation, while also preventing excessive stretching or plastic deformation of the spring due to excessive swinging, thereby protecting the spring performance and extending its service life.

[0032] For example, in the gear shift simulator provided in one embodiment, the gear return structure, such as Figure 2-3 As shown, the height of the limiting groove 31 is adapted to the height of the protrusion 12, which is used to limit the vertical displacement of the straight arm 22 and prevent the straight arm 22 from coming out of the limiting groove 31.

[0033] According to the above embodiment, by matching the height of the limiting groove 31 with the height of the protrusion 12, the straight arm 22 is effectively constrained in the vertical direction. This design eliminates the possibility of the straight arm 22 moving up and down during movement, ensures the stability of the force transmission path, and prevents the risk of the straight arm 22 falling out of the groove due to vibration, thereby improving the reliability of the system.

[0034] For example, in the gear shift simulator provided in one embodiment, the gear return structure, such as Figure 2-3 As shown, the protruding post 11 and the protruding block 12 are located at the two sides of the bottom surface of the stop support block 10, and are arranged symmetrically with the stop rod 40 as the central axis.

[0035] According to the above embodiment, by arranging the protruding post 11 and the protrusion 12 on both sides of the bottom surface of the gear support block 10 and symmetrical about the gear lever 40, the effect is to maximize the lever arm length and optimize the torque transmission efficiency. This symmetrical layout allows the spring force to be converted into a restoring torque with minimal energy loss, while providing a stable and symmetrical mounting base for the torsion spring, ensuring the balance of the restoring action.

[0036] For example, in the gear shift simulator provided in one embodiment, the gear return structure, such as Figure 2-3 As shown, the fastener 13 is a screw cap with a diameter larger than the outer diameter of the protrusion 11, used to axially limit the spring body 21.

[0037] According to the above embodiment, by using a nut with a diameter larger than the outer diameter of the protrusion 11 as a fastener, a simple and reliable axial fixation of the spring body 21 is achieved. This limiting method ensures that the spring will not accidentally fall off the protrusion during operation, facilitates assembly and maintenance, and at the same time, the large contact area of ​​the nut reduces the pressure on the spring end face, avoiding local deformation.

[0038] For example, in the gear shift simulator provided in one embodiment, the gear return structure, such as Figure 2-3 As shown, the torsion spring 20 applies a continuous elastic clamping force to the stop lever 40 through its two straight arms 22, stores elastic potential energy when the stop lever 40 deviates from its initial position, and drives the stop lever 40 to automatically return to the center position when released.

[0039] According to the above embodiment, by applying a continuous elastic clamping force to the shift lever 40 through the torsion spring 20, an intelligent self-centering mechanism based on energy storage and release is established. When the shift lever 40 deviates, the spring stores potential energy; when the external force is released, the spring potential energy is automatically converted into kinetic energy to drive the shift back to center. This process requires no external energy input, achieving true self-driven self-centering, and the self-centering speed is positively correlated with the degree of deviation, which conforms to the principles of ergonomics.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
