Description

Technical Field

[0001] This utility model relates to the technical field of vehicle control mechanisms, and proposes a horizontally placed gear shifting control device. Background Technology

[0002] In automobiles, construction machinery, and agricultural vehicles, the gear shift lever is a core human-machine interface component for controlling the transmission status. To save cab space, facilitate personnel entry and exit, or meet the needs of multi-functional operating platforms, gear shift levers with foldable storage functions are increasingly valued. Traditional foldable gear shift lever structures often achieve this through complex linkage mechanisms, additional locking buttons, or separate hinges, resulting in problems such as bulky structure, cumbersome operation steps, unclear feel, poor reliability, and high cost.

[0003] In the prior art, patent CN202520880205.7 discloses a "lift-type gear shifter," which switches the engagement relationship between the paddles on two gear shift levers and the guide grooves and shift grooves by lifting, thereby switching between two sets of gears. Although this design simplifies the gear shifting operation, its function is limited to switching between different gear groups, and it does not have the function of folding the entire lever down to a horizontal or stowed state, which cannot meet the application scenarios with higher requirements for space utilization.

[0004] Therefore, there is an urgent need for an adjustment lever that is compact in structure, intuitive in operation, can organically integrate gear shifting and horizontal reclining functions, and has a clear gear feel and the ability to prevent misoperation. Utility Model Content

[0005] This invention proposes a horizontally placed gear shifting control device, which solves the problems of complex structure, cumbersome operation steps, and poor anti-misoperation capability of traditional foldable gear levers in related technologies.

[0006] The technical solution adopted by this utility model is: A horizontally oriented gear shifting device, comprising: Base; A support shaft is rotatably mounted on the base. The first swing rocker arm and the second swing rocker arm are symmetrically mounted on the support shaft and can swing around it. The upper part of the first swing rocker arm is provided with a first arc-shaped guide structure. The first arc-shaped guide structure includes an integrally formed first shift adjustment section and a sliding section. The sliding section extends along the first shift adjustment section. The upper part of the second swing rocker arm is provided with a second arc-shaped guide structure. The second arc-shaped guide structure includes an integrally formed second shift adjustment section and a reclining section. The reclining section and the second shift adjustment section are connected in a staggered manner. The lifting control component is movably mounted on the support shaft, with one side adapted to and fitted into the first arc-shaped guide structure and the other side adapted to and fitted into the second arc-shaped guide structure; the lifting control component can move to a horizontally laid-down state in coordination with the first swing arm and the second swing arm.

[0007] As a further technical solution, the total effective stroke of the second shift adjustment section and the reclining section is greater than the total effective stroke of the first arc-shaped guide structure.

[0008] As a further technical solution, both the first arc-shaped guide structure and the second arc-shaped guide structure are provided with a smooth transition structure.

[0009] As a further technical solution, the first shift adjustment section has a downwardly recessed first gear slot in the middle, and the second shift adjustment section has an upwardly recessed second gear slot in the middle; the lifting control component includes: The lifting body is slidably fitted onto the support shaft through the elongated hole; The first shifting engagement component and the second shifting engagement component are symmetrically arranged on the lifting body. The first shifting engagement component can slide along the first shifting adjustment section and the sliding section or be engaged in the first gear position slot along with the lifting body. The second shifting engagement component can slide along the second shifting adjustment section and the sliding section or be engaged in the second gear position slot along with the lifting body.

[0010] As a further technical solution The arc curvature of the reclining section is consistent with that of the second shift adjustment section, and a limiting guide protrusion is provided between the second shift adjustment section and the reclining section. When the second shift engagement component slides to the position of the limiting guide protrusion, the first shift engagement component needs to be disengaged from the first gear slot and enter the sliding section by lifting the lifting body. At the same time, the second shift engagement component crosses the limiting guide protrusion and enters the reclining section.

[0011] As a further technical solution, the lifting control component also includes: An operating lever is mounted on the lifting body, which can drive the lifting body to rotate or rise and fall.

[0012] The beneficial effects of adopting the above technical solution are as follows: This invention integrates gear shifting and horizontal folding functions through the synergistic action of pull-to-unlock and differential guidance. Under normal conditions, pushing the control lever forward or backward causes the two rocker arms to swing synchronously, achieving stable and wobbly gear shifting, with a clear gear feel provided by the ball screws. When folding is required, pulling the control lever upward raises the lifting assembly, which then enters the folding section after passing the limit guide protrusion. Continuing to swing the control lever guides the second rocker arm, which, through the folding section concentric with its shifting trajectory, rotates the support shaft, allowing the control lever to smoothly fold to a horizontal position. The travel difference design of the guide groove creates an additional lock in the folding position, preventing accidental rebound. This design, with its compact and reliable coaxial rocker arm mechanism, and the limit protrusion prevents misoperation, enhancing safety. Attached Figure Description

[0020] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. The utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Reference Figures 1-6 The first embodiment of this utility model proposes a horizontally placed gear shifting control device, which consists of a base 16, a support shaft 1, a first swing rocker arm 2, a second swing rocker arm 3, a lifting control component, and a positioning mechanism.

[0023] like Figure 1 As shown, the base 16 includes a base plate, two parallel vertical plates fixed to the base plate, and a positioning plate connecting the two vertical plates. The two ends of the support shaft 1 are rotatably supported between the two vertical plates through bearings or shaft holes.

[0024] The first swing rocker arm 2 and the second swing rocker arm 3 are symmetrically fitted onto the support shaft 1 through shaft holes and located between the two upright plates. Both can swing independently around the support shaft 1. This is the basis for realizing differential function and mode switching. The first swing rocker arm 2 has an integrally formed first arc-shaped guide structure on its upper part. The core of this structure includes two parts: a first shift adjustment section 4 and a sliding section 5. The first shift adjustment section 4 has a downward recessed middle part to form a first gear position groove 6. Its function is to engage with the first shift mating part 13 in shift mode to provide a clear gear position and holding force, thereby achieving gear locking. The sliding section 5 extends smoothly from one end of the shift adjustment section, providing an unobstructed sliding channel for the shift mating part, allowing the first swing rocker arm 2 to swing freely relative to the shift mating part, thereby completing the folding action.

[0025] The second rocker arm 3 has an integrally formed second arc-shaped guide structure on its upper part. The second shift adjustment section 7 has an upwardly recessed middle part, forming a second gear position slot 9. Its function is to engage with the second shift engagement part 14 in shift mode, and form a vertically offset position with the first gear position slot 6 on both sides. During shift operation, when the first shift engagement part 13 engages with the first gear position slot 6, the operating lever drives the first rocker arm 2 to rotate, thereby completing the shift. At the same time, the second shift engagement part 14 is in the second shift adjustment section 7, preventing it from causing the first rocker arm 2 to rotate. When the second swing rocker arm 3 moves, the second shifting engagement part 14 engages with the second gear position slot 9, and the second swing rocker arm 3 can rotate to shift gears, while the first swing rocker arm 2 will not move. This greatly enhances the convenience and stability of the shifting state. The reclining section 8 is located at one end of the second shifting adjustment section 7. Its key design is that the arc curvature center of the reclining section 8 is consistent with the arc curvature of the second shifting adjustment section 7, and the arc trajectories of the two are parallel. The extended line of the trajectory of the reclining section 8 overlaps with the second gear position slot 9. Its function is to provide a guide trajectory concentric with the shift arc for the second shift engagement 14 in the reclining mode, ensuring that the control lever 11 can rotate smoothly and stably to the horizontal reclining state with the support shaft 1 as the center. It is worth noting that the limiting guide protrusion 15 is located at the connection between the second shift adjustment section 7 and the reclining section 8. Within the normal shift range, it physically prevents the shift engagement from accidentally sliding into the reclining section 8, preventing misoperation. Only after actively pulling to unlock can the engagement cross over and enter the reclining section 8 under its guidance.

[0026] The key lies in the fact that during the folding operation, the longer guide groove of the second swing arm 3 forces a relative displacement difference between the shifting components on both sides of the lifting assembly. The important functional result of this differential design is that when the control lever 11 swings to a specific folding position (e.g., close to horizontal), the first shifting component 13 is constrained at the end of the sliding section 5. In order for the control lever to be fully folded down, the first swing arm 2 needs to be engaged in a temporary gear, providing an additional mechanical locking point for the folding state. This effectively prevents the lever from automatically springing back from the folding position due to vehicle vibration or accidental contact, ensuring the reliability and safety of the storage state.

[0027] Meanwhile, in this embodiment, the smooth transition structure is specifically designed with rounded chamfers at the connection points of each segment. The connection points between the first shift adjustment segment 4 and the sliding segment 5, and the connection points between the second shift adjustment segment 7 and the reclining segment 8 (including both sides of the limiting guide protrusion 15) are all rounded, which can reduce the frictional resistance when the shift mating parts slide, avoid jamming, reduce component wear, and improve service life.

[0028] Similarly, in this design, the ball screw is threaded onto the positioning plate and locked with a nut. When the arc-shaped positioning groove moves to the position of the ball screw, the ball bearings of the ball screw are pressed against the arc-shaped positioning groove under the action of the spring. As the rocker arm swings, the ball screw disengages from the arc-shaped positioning groove. During the process of the ball screw entering and disengaging from the arc-shaped positioning groove, the resistance will give the operating lever obvious feedback. It is worth noting that both the first rocker arm 2 and the second rocker arm 3 have a limiting part at the bottom. When the ball screw abuts against the limiting part during gear switching, the rocker arm cannot move, and the gear switching is completed.

[0029] The limiting part is a protruding structure at the end of the arc-shaped groove at the bottom of the rocker arm. Its contact surface with the ball screw is made of wear-resistant material (such as hardened steel) and can withstand the impact force during gear shifting. At the same time, the curvature of the arc-shaped groove is designed according to the gear shift stroke of the transmission to ensure that the swing angle of the rocker arm is precisely matched with the gear shift stroke of the transmission, so as to achieve accurate gear switching. In addition, the threaded connection of the ball screw can adjust the spring preload by rotating it, thereby adjusting the lightness or heaviness of the gear feedback feel to adapt to the operating needs of different vehicle models. The nut is a lock nut to prevent the ball screw from loosening due to vehicle vibration, thus improving the structural reliability.

[0030] Furthermore, the rocker arm also has a connecting part that connects to the shifting actuator. The connecting part is an ear seat structure with a pin hole. The pin hole is provided with an anti-slip keyway. It is detachably connected to the connecting rod of the shifting actuator through the pin shaft, which is convenient for installation, debugging and later maintenance. The installation directions of the two connecting parts are symmetrical, ensuring that the swinging action of the two rocker arms is transmitted to the shifting actuator synchronously, avoiding shifting deviation.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
