Description

Technical Field

[0001] This utility model belongs to the technical field of gear shifting mechanisms, specifically relating to an automatic gear shifting mechanism for linear push-rod type gears. Background Technology

[0002] As a crucial training equipment, target vehicles are increasingly used in various training scenarios, placing higher demands on unmanned target vehicles with high mobility and off-road capabilities. During operation, remote control of the target vehicle's direction, throttle, braking, engine shutdown, and gear shifting is essential. The effectiveness and stability of gear shifting are key challenges for drive-by-wire target vehicles. Current technology uses an electric push rod for remote gear shifting, where the gear lever is exposed, and remote control is concentrated on the handle or control screen. The electric push rod provides the power for gear shifting. Consequently, if the electric push rod malfunctions, gear shifting will be impossible, and personnel cannot intervene, requiring assistance. Therefore, we have further improved the automatic gear shifting mechanism for linear push rod gear shifters and proposed an automatic gear shifting mechanism for linear push rod gear shifters. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where manual gear shifting is impossible, and to propose an automatic gear shifting mechanism for linear push-rod type gear shifters. This automatic gear shifting mechanism for linear push-rod type gear shifters features a detachable design for the shift lever and electric push rod, offering both automatic and manual shifting modes that can be freely switched, making it more practical.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an automatic gear shifting mechanism for a linear push-rod type gear shifter, including a stop lever, a shift handle, and an electric push rod. The stop lever is mounted on a gear shifter base. The electric push rod is fixedly mounted on one side of the stop lever via a fixing bracket. The stop lever has a pipe clamp connection part and a shift handle connection part. The pipe clamp connection part is a polygonal column structure, and a pipe clamp is fitted onto the pipe clamp connection part. The pipe clamp has a hooking part on the side corresponding to the electric push rod. The hooking part has a hooking groove with a downward opening structure. A hooking shaft is horizontally fixed on the output shaft of the electric push rod, and the hooking shaft hooks into the hooking groove. The shift handle is mounted on the shift handle connection part by sliding up and down. The two ends of the shift handle connection part have a lower threaded part and an upper threaded part for fixing the shift handle, respectively.

[0006] Furthermore, the minimum stroke of the electric push rod allows the stop lever to be engaged in reverse (R) gear.

[0007] Furthermore, the width of the hanging groove is adapted to the width of the hanging shaft.

[0008] Furthermore, the lower threaded portion and the upper threaded portion are external threaded structures, and the bottom of the shift lever is provided with an internal threaded structure that is adapted to the lower threaded portion and the upper threaded portion.

[0009] Furthermore, the top of the gear lever connection is provided with a slider, and the gear lever is provided with a groove that matches the outer diameter of the slider, and the slider is slidably disposed in the groove.

[0010] Furthermore, a spring is sleeved on the stop bar and located below the pipe clamp, and a limiting platform for supporting the spring is fixed on the stop bar, with the spring compressed and supported between the limiting platform and the pipe clamp.

[0011] Furthermore, it also includes a sealing plate, which is disposed above the automatic gear shifting mechanism. The sealing plate has a cover plate corresponding to the position of the gear lever, and the cover plate has a semi-transparent structure.

[0012] Furthermore, the top of the gear lever is provided with a transparent part, and a light source is embedded in the transparent part, and the light source is connected to a power source.

[0013] The automatic gear-shifting mechanism for linear push-rod type gears proposed in this utility model has the following advantages:

[0014] (1) The gear lever and electric push rod of this utility model adopt a separable design. Once the electric push rod malfunctions, the hidden gear lever can be pulled out. At this time, the pipe clamp used to connect the gear lever and the electric push rod can be raised to separate the gear lever from the electric push rod, and the automatic gear shifting can be switched to manual gear shifting. In this way, even if the electric push rod malfunctions, it can be switched to manual operation to smoothly shift gears and drive the vehicle to the repair shop.

[0015] (2) The gear lever of this utility model is designed to be hidden, which improves the aesthetics of the gear shift position and makes the external structure more concise. A light source is set on the top of the gear lever so that the current gear position can be observed. At the same time, it can also improve the fun of the car during the gear shifting process.

[0026] Example 1

[0027] See Figures 1-3 An automatic gear-shifting mechanism for a linear push-rod type gear position includes a stop lever 2, a gear lever 4, and an electric push rod 5. The stop lever 2 is mounted on a gear position base 1. The electric push rod 5 is fixedly mounted on one side of the stop lever 2 via a fixing bracket 51. The minimum stroke of the electric push rod 5 allows the stop lever 2 to be engaged in reverse gear (R). Automatic gear shifting is achieved by pushing the stop lever 2 with the electric push rod 5. The stop lever 2 is provided with a pipe clamp connection part 22 and a gear lever connection part 23. The pipe clamp connection part 22 is used to connect a pipe clamp 3, and the gear lever connection part 23 is used to connect a gear lever 4.

[0028] The pipe clamp connection part 22 has a polygonal column structure, and a pipe clamp 3 is fitted onto the pipe clamp connection part 22. The polygonal column structure of the pipe clamp connection part 22 can effectively limit the pipe clamp 3, preventing the pipe clamp 3 from rotating on the pipe clamp connection part 22. When the electric push rod 5 pushes the stop rod 2, the connection between the pipe clamp 3 and the stop rod 2 can be made more stable. The pipe clamp 3 has a hanging part 31 on one side corresponding to the electric push rod 5. The hanging part 31 has a hanging groove 32 with a downward opening structure. A hanging shaft 52 is horizontally fixed on the output shaft of the electric push rod 5. The hanging shaft 52 is hung in the hanging groove 32. The width of the hanging groove 32 is adapted to the width of the hanging shaft 52. After the pipe clamp 3 is fitted onto the pipe clamp connection part 22, the hanging groove 32 behind the pipe clamp 3 will hang on the hanging shaft 52 on the side of the output shaft of the electric push rod 5. As the output shaft of the electric push rod 5 reciprocates, it pushes the stop rod 2 to change gears.

[0029] The gear lever 4 is mounted on the gear lever connecting part 23 by sliding up and down. The two ends of the gear lever connecting part 23 are respectively provided with a lower threaded part 24 and an upper threaded part 25 for fixing the gear lever 4. The lower threaded part 24 and the upper threaded part 25 are external thread structures. The bottom of the gear lever 4 is provided with an internal thread structure that matches the lower threaded part 24 and the upper threaded part 25. When the pipe clamp 3 is sleeved on the pipe clamp connecting part 22, the gear lever 4 is connected to the lower threaded part 24. On the one hand, the gear lever 4 can be moved down to facilitate the hiding of the gear lever 4. On the other hand, it plays a role in positioning the pipe clamp 3, fixing the pipe clamp 3 on the pipe clamp connecting part 22, preventing it from moving upward, and ensuring the stability of the connection between the pipe clamp 3 and the pipe clamp connecting part 22 during gear shifting. When it is necessary to switch to manual shifting, rotate the shift lever 4 in the reverse direction to disengage the lower part of the shift lever 4 from the lower threaded part 24, and move the shift lever 4 upward so that the external thread of the lower part of the shift lever 4 is fixedly connected to the upper threaded part 25 of the shift lever connecting part 23, thereby raising the shift lever 4 and moving it to the outside for manual shifting. At this time, since the pipe clamp 3 is no longer limited by the shift lever 4, the pipe clamp 3 can move upward, causing the hanging groove 32 to disengage from the hanging shaft 52, so that the electric push rod 5 does not affect manual shifting. In order to ensure the stability of the shift lever 4's up and down movement, a slider 26 is provided at the top of the shift lever connecting part 23, and a groove 42 with a size that matches the outer diameter of the slider 26 is provided inside the shift lever 4. The slider 26 is slidably disposed in the groove 42.

[0030] When the shift lever 4 moves upward, in order to allow the pipe clamp 3 to move upward automatically and no longer fall down to interfere with gear shifting, a spring 6 is fitted on the shift lever 2 and below the pipe clamp 3. A limiting platform 21 for supporting the spring 6 is fixed on the shift lever 2. The spring 6 is compressed and supported between the limiting platform 21 and the pipe clamp 3. After the limiting of the pipe clamp 3 is released, the pipe clamp 3 is always below the shift lever 4 under the action of the spring 6 and is always separated from the electric push rod 5, which can effectively avoid interfering with manual gear shifting.

[0031] The automatic gear shifting mechanism of this utility model for linear push-rod type gear shifting adopts a separable design for the shift lever 2 and electric push rod 5. Once the electric push rod 5 malfunctions, the hidden shift lever 4 can be pulled out. At this time, the pipe clamp 3 used to connect the shift lever 2 and the electric push rod 5 can be raised to separate the shift lever 2 and the electric push rod 5, switching the automatic gear shifting to manual gear shifting. In this way, even if the electric push rod 5 malfunctions, it can be switched to manual operation for smooth gear shifting, and the gear shifting can drive the vehicle to the repair shop.

[0032] Example 2

[0033] Reference Figure 4 In another preferred embodiment of this utility model, the difference from Embodiment 1 is that it also includes a sealing plate 7. The sealing plate 7 is disposed above the automatic gear shifting mechanism. A cover plate 71 is provided on the sealing plate 7 corresponding to the position of the gear lever 4. The cover plate 71 is a semi-transparent structure. A transparent part 43 is provided on the top of the gear lever 4, and a light source 44 is embedded in the transparent part 43. The light source 44 is connected to a power source. In automatic gear shifting mode, the gear lever 4 is hidden under the cover plate 71, realizing a hidden structure, improving the aesthetics of the gear shifting position, and making the external structure more concise. The light source 44 is provided on the top of the gear lever 4, which allows observation of the current gear position and also enhances the fun of the car during gear shifting.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
