Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural machinery, and specifically relates to a pressing type gear shifter. BACKGROUND

[0002] In the development process of modern agriculture, agricultural machinery, as an important material basis of modern agriculture, runs through all aspects of agricultural production, from the initial ploughing operation to subsequent sowing, fertilization, irrigation, harvesting, transportation and agricultural product processing, all of which cannot be separated from the efficient operation of agricultural machinery. Agricultural machinery significantly improves the efficiency of agricultural production, greatly reduces the labor intensity, and also plays a key role in improving the yield and quality of agricultural products.

[0003] However, in the actual use of agricultural machinery, gear shifting is a crucial aspect of controlling the machine's travel speed and operating status. The rationality of the design of its control system directly affects the overall performance of the agricultural machinery and the driver's operating experience. Currently, agricultural machinery needs to flexibly adjust its travel speed according to different operational needs, such as the looseness of the soil, the planting density of crops, and the progress of the operation. This adjustment process is usually achieved through a joystick. The joystick drives the transmission control system through spatial displacement and force transmission, thereby changing the gear position of the agricultural machinery's gearbox to achieve the purpose of changing the travel speed. Currently, there are two common combined movement modes in the transmission control systems of agricultural machinery on the market. One mode is the combination movement mode of left and right or pressing to select gears left and right and shift gears forward and backward. In this mode, the driver needs to move the joystick left and right to select different gears and then move it forward and backward to shift gears. This operation mode requires a large range of motion because the joystick needs sufficient amplitude to accurately select gears when moving left and right. This leads to a deterioration in the ergonomics of the machine. The driver needs to frequently move his arm and body in large amplitude during operation, which increases the fatigue of operation. At the same time, in order to meet the large range of motion requirements of the joystick, the space of the cab must also be increased accordingly. This not only increases the manufacturing cost of agricultural machinery, but may also result in a less compact cab layout, affecting the driver's operating vision and ease of operation. Another common combination of movement is pressing and moving back and forth. In this method, the driver needs to press the lever first and then move it back and forth to complete the gear shifting operation. However, this method has obvious drawbacks. When pressing the lever, the driver's body needs to bear a certain amount of force, which will affect the driver's body coordination. For example, during long-term operation, the driver may feel fatigued due to uneven force on the body, and may even lead to incorrect posture, increasing the burden on the waist, neck and other parts. This not only reduces the safety of operation, but may also pose a potential threat to the driver's health. In addition, the user experience of this method is not good. The driver may feel that the operation is not smooth and natural, affecting the accuracy and efficiency of operation. Utility Model Content

[0004] The purpose of this invention is to provide a push-button gear shifter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Push-button gear shifters include:

[0007] The base plate has several mounting holes at its top end, and a support is fixedly mounted on the top end of the base plate.

[0008] A gear shifting mechanism is provided on one side of a support. The gear shifting mechanism includes a movable block movably installed inside the support. A control lever is fixedly installed on one side of the movable block. Side plate 1 and side plate 2 are movably installed inside the support. Side plate 1 has a slide groove 1 and a slot 1 on one side. The slot 1 is located above the slide groove 1. A retaining shaft 1 is fixedly installed on one side of the movable block and is inserted into the slot 1. Side plate 2 has a slide groove 2 and a slot 2 on one side. The slot 2 is located below the slide groove 2. A retaining shaft 2 is fixedly installed on one side of the movable block and is inserted into the slot 2.

[0009] Preferably, the support has a first side plate and a second side plate movably mounted inside via bearings. The movable block is disposed between the first side plate and the second side plate. The first retaining shaft is disposed on the side of the movable block near the first side plate, and the second retaining shaft is disposed on the side of the movable block near the second side plate. The first retaining shaft extends into the first sliding groove, and the second retaining shaft extends into the second sliding groove.

[0010] Preferably, the support is provided with two flexible shafts, which are located below side plate one and side plate two respectively. Both side plate one and side plate two are provided with grooves, which are corresponding to the flexible shafts, and the flexible shafts are inserted into the grooves.

[0011] Preferably, the first retaining shaft is used to cooperate with the first retaining groove to drive the first side plate to swing, and the second retaining shaft is used to cooperate with the second retaining groove to drive the second side plate to swing.

[0012] Preferably, the first side plate and the second side plate drive the flexible shaft to move through the groove.

[0013] Preferably, the dimensions of the first card shaft and the first card slot are adapted to each other, and the dimensions of the second card shaft and the second card slot are adapted to each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model changes the movement mode of the control lever from the traditional combination of forward and backward left and right movement or up and down forward and backward movement to the method of finger lifting and back and forth swinging for gear shifting. This innovative design avoids the problem of the control lever needing a large space to move when selecting gears left and right in the traditional system. In the traditional control system, the left and right movement of the control lever requires a large space range, which requires the cab to have enough width to accommodate the movement trajectory of the control lever. However, with the push-type gear shifter of this application, the driver only needs to lift and swing his fingers to complete the gear shifting operation, which greatly reduces the space requirement of the cab.

[0016] (2) The push-button shifter of this utility model does not require the body to exert force from left to right when shifting gears. The shifting can be completed by the movement of the hand. This operation method is more in line with the natural movement law of the human body and will not put extra burden on the driver's body. The driver can maintain a relatively stable body posture during operation, better concentrate his attention, and improve the safety of operation. In addition, this application also forms a mechanical interlocking mechanism through a preset height difference, which effectively prevents accidental activation of the lifting and pressing modes. During operation, the corresponding shifting action can only be triggered when the control lever is accurately lifted or pressed to the preset height, avoiding gear switching errors caused by misoperation and further ensuring the safety of the driver.

[0017] (3) This utility model forms a mechanical interlock mechanism by setting a preset height difference, which effectively prevents accidental touches in the lifting and pressing modes. During operation, the locking shaft can only enter the corresponding slot when the control lever is accurately lifted or pressed to the preset height, causing the side plate to swing and thus realize gear switching. If the control lever is not accurately operated to the preset height, the locking shaft will not be able to enter the slot, and the side plate will not swing, thereby avoiding gear switching errors caused by accidental touches. This mechanical interlock mechanism greatly improves the accuracy of gear switching and ensures the stable operation of agricultural machinery under various operating conditions.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1 - Figure 7 As shown, the push-button gear shifter includes:

[0029] The base plate 1 has several mounting holes 11 at its top, and a support 12 is fixedly installed at the top of the base plate 1.

[0030] The shifting mechanism 2 is located on one side of the support 12. The shifting mechanism 2 includes a movable block 21 that is movably installed inside the support 12. A control lever 22 is fixedly installed on one side of the movable block 21. Side plate 1 23 and side plate 24 are movably installed inside the support 12. Side plate 1 23 has a slide groove 25 and a slot 26 on one side. Slot 26 is located above slide groove 25. A retaining shaft 27 is fixedly installed on one side of the movable block 21 and is inserted into slot 26. Side plate 24 has a slide groove 28 and a slot 29 on one side. Slot 29 is located below slide groove 28. A retaining shaft 210 is fixedly installed on one side of the movable block 21 and is inserted into slot 29.

[0031] Specifically, side plate 1 23 and side plate 24 are movably mounted inside the support 12 via bearings. A movable block 21 is positioned between side plate 1 23 and side plate 24. A retaining shaft 1 27 is positioned on the side of the movable block 21 near side plate 1 23, and a retaining shaft 210 is positioned on the side of the movable block 21 near side plate 24. Retaining shaft 1 27 extends into slide groove 1 25, and retaining shaft 210 extends into slide groove 28. Two flexible shafts 211 are installed inside the support 12, located on side plate 1 23 and side plate 24 respectively. Below 24, both side plate 1 23 and side plate 24 have grooves 212. The grooves 212 are correspondingly set with flexible shafts 211. Flexible shafts 211 are inserted into the grooves 212. Snap shaft 1 27 is used to cooperate with snap groove 1 26 to drive side plate 1 23 to swing. Snap shaft 210 is used to cooperate with snap groove 29 to drive side plate 24 to swing. Side plate 1 23 and side plate 24 drive flexible shaft 211 to move through the grooves 212. Snap shaft 1 27 and snap groove 1 26 are matched in size. Snap shaft 210 and snap groove 29 are matched in size.

[0032] As can be seen from the above, the base plate 1 serves as the mounting foundation for the entire gear shifter. Several mounting holes 11 are evenly distributed at its top. These mounting holes 11 are designed with standard dimensions to facilitate matching with the mounting structure inside the agricultural machinery cab. By passing bolts through the mounting holes 11, the base plate 1 can be securely installed in a suitable position within the cab, ensuring the stability of the gear shifter during use. The base plate 1 is made of high-strength alloy material, possessing good rigidity and corrosion resistance, capable of withstanding various forces and vibrations generated during gear shifting operations. The support 12 is fixedly installed at the top of the base plate 1 and is a key component supporting the gear shifting mechanism 2. The interior of the support 12... The hollow structure provides space for the movement of the shift mechanism 2. The movable block 21 is movably installed inside the support 12. A control lever 22 is fixedly installed at the top of the movable block 21. The control lever 22 is ergonomically designed with a non-slip textured surface for easy grip by the driver. A retaining pin 27 and a retaining pin 210 are fixedly installed near the side plate 1 23 and side plate 24, respectively. The diameters of retaining pins 27 and 210 match the widths of slide grooves 25 and 28, and slots 26 and 29, ensuring smooth insertion and precise motion transmission. Side plates 23 and 24 are connected by bearings. The flexible shaft 211 is installed inside the support 12 and can rotate freely around the bearing. Side plate 23 has a sliding groove 25 and a retaining groove 26, with retaining groove 26 positioned above sliding groove 25. Sliding groove 25 has an arc-shaped structure. When retaining shaft 27 reaches a preset height, it accurately enters retaining groove 26. Side plate 24 has a sliding groove 28 and a retaining groove 29, with retaining groove 29 positioned below sliding groove 28. Sliding groove 28 also has an arc-shaped structure. Both side plates 23 and 24 have grooves 212 at their bottoms. The shape of the grooves 212 matches the shape of the flexible shaft 211, ensuring that the flexible shaft 211 can be securely held in the grooves 212. Inside 12, effective transmission between the side plate and the flexible shaft 211 is achieved. Two flexible shafts 211 are provided, respectively located below the first side plate 23 and the second side plate 24. The flexible shafts 211 are made of high-strength and high-flexibility materials and have good tensile and compressive strength. One end of the flexible shaft 211 is connected to the gearbox of the agricultural machinery, and the other end is locked in the groove 212 of the first side plate 23 or the second side plate 24. When the first side plate 23 or the second side plate 24 swings, the flexible shaft 211 is driven to move through the groove 212. The flexible shaft 211 transmits the motion to the gearbox, triggering the engagement or disengagement of the corresponding gear in the gearbox, thereby realizing gear switching.

[0033] Working principle: When the driver grips the control lever 22 and lifts it upwards, the movable block 21 moves upwards under the action of the control lever 22. When the movable block 21 is lifted to the preset height, the first locking shaft 27 reaches the position of the first locking slot 26 and inserts into the first locking slot 26. At this time, the second locking shaft 210 moves inside the second sliding groove 28. Since the second locking slot 29 is below the second sliding groove 28, the second locking shaft 210 will not contact the second side plate 24. After the first locking shaft 27 is inserted into the first locking slot 26, it contacts the second side plate 24. 23 forms a tight connection. When the driver moves the control lever 22 forward or backward, the control lever 22 drives the movable block 21 to swing back and forth. The movable block 21 transmits force to the side plate 23 through the retaining shaft 27, causing the side plate 23 to swing back and forth around the bearing. The flexible shaft 211 in the groove 212 at the bottom of the side plate 23 moves with the swing of the side plate 23. The flexible shaft 211 transmits the motion to the gearbox, triggering the engagement or disengagement of the corresponding gear in the gearbox, thereby realizing the gear shift of the gearbox.

[0034] When the driver grips the control lever 22 and presses it down, the movable block 21 moves downward under the action of the control lever 22. When the movable block 21 is pressed down to the preset height, the second retaining shaft 210 reaches the position of the second retaining groove 29 and inserts into the second retaining groove 29. At this time, the first retaining shaft 27 moves in the first sliding groove 25 and does not contact the first side plate 23. After the second retaining shaft 210 is inserted into the second retaining groove 29, it forms a tight connection with the second side plate 24. When the driver moves the control lever 22 forward or backward, the control lever 22 drives the movable block 21 to swing back and forth. The movable block 21 transmits force to the second side plate 24 through the second retaining shaft 210, causing the second side plate 24 to swing back and forth around the bearing. The flexible shaft 211 in the groove 212 at the bottom of the second side plate 24 moves with the swing of the second side plate 24. The flexible shaft 211 transmits the motion to the gearbox, triggering the engagement or disengagement of the corresponding gear in the gearbox, thereby realizing the secondary shift of the gearbox gear.
