Description

Technical Field

[0001] This utility model belongs to the technical field of gear shift levers, specifically a gear shift lever with damping effect. Background Technology

[0002] The damped gear shift lever retains the core functions of a regular gear shift lever in shifting gears and matching engine power with wheel speed. It optimizes the driving experience and safety through a built-in damping structure. Its damping characteristics can buffer the impact force when shifting gears, preventing the gear shift lever from shaking or being accidentally engaged due to excessive operating force. This makes the gear shifting process smoother and more precise, while reducing the vibration and noise generated by mechanical transmission and improving driving quietness.

[0003] The installation position and structure of the ball screw in the gear shift lever are quite special. The ball screw in the damping structure usually requires precise angle and position to ensure the damping effect and accurate gear switching. During installation, the screw angle needs to be repeatedly adjusted to ensure that the ball and the corresponding groove or damping structure are correctly matched. This process is time-consuming and labor-intensive, and also requires a high level of technical skills from maintenance personnel. In addition, the ball screw is usually small and may be hidden in the complex structure inside the gear shift lever, with limited operating space. The use of tools is restricted during disassembly and installation, which increases the difficulty of replacement and reduces the replacement efficiency of the ball screw. Therefore, this application proposes a gear shift lever with a damping effect. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an adjustment lever with damping effect, which effectively solves the problem of inconvenient replacement of the glass ball screw in the adjustment lever.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable gear lever with damping effect, comprising a base and an adjusting and disassembling mechanism, wherein a side wall is fixedly installed on the upper end of the base; the adjusting and disassembling mechanism includes a gear lever installed on the base, wherein multiple concave openings are fixedly installed on the gear lever, and adjusting components that slide against the inner wall of the concave openings are slidably connected within the concave openings; a through opening is fixedly installed on the side wall, wherein a fixing block that slides against the inner wall of the through opening is slidably connected within the through opening, and the fixing block is fixedly connected to the adjusting component; two opposing fixing plates are fixedly installed on the side wall, the two fixing plates being located on both sides of the fixing block; a sliding groove is provided on the fixing block, wherein a limiting bolt that slides against the inner wall of the sliding groove is slidably connected within the sliding groove; and an installation component capable of limiting the limiting bolt is installed on the fixing plate.

[0006] Preferably, the adjusting component includes a mounting cylinder fixedly connected to the fixing block, and a mounting plate slidably connected inside the mounting cylinder and slidingly abutting against the inner wall of the mounting cylinder.

[0007] Preferably, a first spring is fixedly installed on the mounting plate and the mounting cylinder, and a steel ball is fixedly installed on the mounting plate. The steel ball passes through the mounting cylinder and is slidably connected to it, and the steel ball slides against the inner wall of the concave opening.

[0008] Preferably, an installation frame is fixedly installed on the upper end of the base, and a rotating rod is fixedly installed on the upper end of the stop lever, which passes through the installation frame and is rotatably connected to the installation frame.

[0009] Preferably, a turntable is fitted onto the rotating rod and fixedly connected thereto. The turntable is located above the mounting frame, and multiple handles are fixedly installed on the turntable.

[0010] Preferably, the mounting component includes a through groove disposed on the fixed plate, a limiting bolt slidingly abutting against the inner wall of the through groove, and a second spring fixedly mounted on the limiting bolt and the fixed plate.

[0011] Preferably, a through-hole is fixedly installed on the base, the stop rod slides against the inner wall of the through-hole, the base is provided with an annular groove opposite to the through-hole, and a circular ring plate is fitted on the stop rod and fixedly connected thereto, the circular ring plate slides against the inner wall of the annular groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an adjustment and disassembly mechanism, and utilizing the cooperation between the limit bolt, the second spring, and the fixing block, pulling the limit bolt can cause it to leave the slide groove, so that the fixing block is no longer limited, thereby removing the ball screw. The new ball screw is then positioned opposite the through-hole, and pushing the fixing block can move the mounting cylinder. The moving fixing block will slide against the inner wall of the through-hole. When the limit bolt is positioned opposite the slide groove, releasing the limit bolt will cause the second spring to move the limit bolt, which will slide against the inner wall of the slide groove, thus limiting the fixing block and completing the replacement of the ball screw. This avoids the need for manual installation using a large number of screws, improving the efficiency of ball screw disassembly and assembly. At the same time, the cooperation between the concave opening, the ball screw, and the stop lever can meet the needs of small-amplitude precise adjustment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-6 The present invention includes a base 1 and an adjustment and disassembly mechanism. A side wall 2 is fixedly installed on the upper end of the base 1. The adjustment and disassembly mechanism includes a stop rod 9 installed on the base 1. A through-hole 20 is fixedly installed on the base 1, and the stop rod 9 slides against the inner wall of the through-hole 20. An annular groove 7 is provided on the base 1 opposite to the through-hole 20. A circular ring plate 8 is sleeved on the stop rod 9 and fixedly connected thereto. The circular ring plate 8 slides against the inner wall of the annular groove 7. An installation frame 3 is fixedly installed on the upper end of the base 1. A rotating rod 4 is fixedly installed on the upper end of the stop rod 9, passing through the installation frame 3. The rotating rod 4 is rotatably connected to the installation frame 3. A turntable 5 is sleeved on the rotating rod 4 and fixedly connected thereto. The turntable 5 is located above the installation frame 3. Multiple handles 6 are fixedly installed on the turntable 5.

[0024] A plurality of concave openings 14 are fixedly installed on the gear lever 9. An adjusting component is slidably connected inside the concave opening 14 and slides against the inner wall of the concave opening 14. The adjusting component includes a mounting cylinder 15 fixedly connected to the fixing block 19. A mounting plate 17 is slidably connected inside the mounting cylinder 15 and slides against the inner wall of the mounting cylinder 15. A first spring 18 is fixedly installed on the mounting plate 17 and the mounting cylinder 15. A steel ball 16 is fixedly installed on the mounting plate 17. The steel ball 16 passes through the mounting cylinder 15 and slides against it. The steel ball 16 slides against the inner wall of the concave opening 14.

[0025] In this system, the first spring 18 built into the glass ball screw is in a slightly compressed state. Under the thrust of the first spring 18, the mounting plate 17 will cause the steel ball 16 to press tightly against the outer surface of the gear lever 9. If the steel ball 16 is in a position other than the concave opening 14, the steel ball 16 will be compressed by the surface of the gear lever 9, and the first spring 18 will further store energy. At this time, the gear lever 9 will be subjected to a certain damping force and will not be able to rotate freely. When working, the user pushes the throttle 6, which will drive the turntable 5 to rotate. The turntable 5 will drive the rotating rod 4 to rotate, and the rotating rod 4 will drive the gear lever 9 to rotate. When the concave opening 14 on the gear lever 9 rotates to the position of the steel ball 16, the first spring 18 releases its stored energy and pushes the steel ball 16 to embed into the concave opening 14. The steel ball 16 will slide against the inner wall of the concave opening 14, and the fit between the steel ball 16 and the concave opening 14 will form a positioning resistance. The user can perceive clear gear shift feedback, damping and precision control.

[0026] As the gear lever 9 continues to rotate, the steel ball 16 moves out of the concave opening 14 and is compressed again by the surface of the gear lever 9 at the non-concave opening 14 position. The first spring 18 re-stores energy, and the damping force is restored. Since the concave openings 14 are evenly distributed (number N), the gear lever 9 can complete a gear shift every 360° / N rotations, achieving fine-tuning of the gear lever 9's adjustment precision. According to the formula d=P / N (where P is the "equivalent pitch" of the gear lever 9, i.e., the linear adjustment amount corresponding to one revolution of the gear lever 9; N is the number of grooves), the fine-tuning precision can be accurately calculated, thereby meeting the needs of small-amplitude precise adjustment.

[0027] A through-hole 21 is fixedly installed on the side wall 2. A fixing block 19 is slidably connected inside the through-hole 21 and slides against the inner wall of the through-hole 21. The fixing block 19 is fixedly connected to the adjusting component. Two opposing fixing plates 22 are fixedly installed on the side wall 2. The two fixing plates 22 are located on both sides of the fixing block 19. The fixing block 19 is provided with a sliding groove 10. A limiting bolt 11 is slidably connected inside the sliding groove 10 and slides against the inner wall of the sliding groove 10. An installation component that can limit the limiting bolt 11 is installed on the fixing plate 22. The installation component includes a through groove 13 provided on the fixing plate 22. The limiting bolt 11 slides against the inner wall of the through groove 13. A second spring 12 is fixedly installed on the limiting bolt 11 and the fixing plate 22.

[0028] The mounting cylinder 15, mounting plate 17, steel ball 16, and first spring 18 constitute a ball screw. When the ball screw needs to be disassembled and replaced, pulling the limit bolt 11 will cause the limit bolt 11 to move away from the slide groove 10, and the second spring 12 will be stretched. The fixing block 19 will no longer be limited. Pulling the fixing block 19 will cause the mounting cylinder 15 to move, which in turn will cause the first spring 18 to move. The first spring 18 will then cause the mounting plate 17 to move, which in turn will cause the steel ball 16 to move, thereby moving the ball screw and allowing it to be disassembled. After removal, the new ball screw is positioned opposite the through-hole 21. Pushing the fixing block 19 will cause the mounting cylinder 15 to move. The moving fixing block 19 will slide against the inner wall of the through-hole 21. When the limiting bolt 11 is positioned opposite the slide groove 10, the limiting bolt 11 is released. The second spring 12 will drive the limiting bolt 11 to move. The moving limiting bolt 11 will slide against the inner wall of the slide groove 10, thereby limiting the fixing block 19 and completing the replacement of the ball screw. This avoids the need for manual installation using a large number of screws and improves the efficiency of disassembling and assembling the ball screw.

[0029] Working principle: When working, the user pushes the throttle 6, which drives the turntable 5 to rotate. The turntable 5 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the gear lever 9 to rotate. When the concave opening 14 on the gear lever 9 rotates to the position of the steel ball 16, the first spring 18 releases its stored energy, pushing the steel ball 16 to embed into the concave opening 14. The steel ball 16 slides against the inner wall of the concave opening 14, and the fit between the steel ball 16 and the concave opening 14 forms a positioning resistance. The user can perceive clear gear shift feedback, damping and precision control.

[0030] As the gear lever 9 continues to rotate, the steel ball 16 moves out of the concave opening 14 and is compressed again by the surface of the gear lever 9 at the non-concave opening 14 position. The first spring 18 re-stores energy, and the damping force is restored. Since the concave openings 14 are evenly distributed (number N), the gear lever 9 can complete a gear shift every 360° / N rotations, achieving fine-tuning of the gear lever 9's adjustment precision. According to the formula d=P / N (where P is the "equivalent pitch" of the gear lever 9, i.e., the linear adjustment amount corresponding to one revolution of the gear lever 9; N is the number of grooves), the fine-tuning precision can be accurately calculated, thereby meeting the needs of small-amplitude precise adjustment.

[0031] When it is necessary to disassemble and replace the glass ball screw, pulling the limit pin 11 will cause the limit pin 11 to move away from the slide groove 10, and the second spring 12 will be stretched. The fixing block 19 will no longer be limited. Pulling the fixing block 19 will cause the mounting cylinder 15 to move. The mounting cylinder 15 will cause the first spring 18 to move. The first spring 18 will cause the mounting plate 17 to move. The mounting plate 17 will cause the steel ball 16 to move, thereby causing the glass ball screw to move, and then the glass ball screw can be removed. The new glass ball screw can then be connected to the through hole 21. With relative positioning, pushing the fixing block 19 can drive the mounting cylinder 15 to move. The moving fixing block 19 will slide against the inner wall of the through-hole 21. When the limiting bolt 11 is positioned relative to the slide groove 10, the limiting bolt 11 is released, and the second spring 12 will drive the limiting bolt 11 to move. The moving limiting bolt 11 will slide against the inner wall of the slide groove 10, thereby completing the limiting of the fixing block 19, and thus completing the replacement of the glass ball screw. This avoids the need for manual installation using a large number of screws and improves the efficiency of glass ball screw disassembly and assembly.
