Description

Technical Field

[0001] This utility model relates to the field of electronic control technology, specifically to an electronic control handle. Background Technology

[0002] In agricultural machinery operation, the control handle is a key component for controlling various functions of the harvester. Traditional harvester control handles are mostly mechanical structures, driving hydraulic valves through multi-link linkages, which have several shortcomings. For example, mechanical handles have limited operational precision, making it difficult to achieve precise fine-tuning when controlling complex operations such as the harvester's travel speed, blade raising and lowering, and steering. Furthermore, after prolonged use, mechanical handles are prone to wear and tear, leading to changes in operating feel and malfunctions. In addition, traditional handles have relatively limited functionality and cannot meet the needs of intelligent, multi-functional harvester operation; for instance, they cannot be easily integrated with the harvester's automated control system, nor can they quickly switch between different operating modes. Utility Model Content

[0003] The purpose of this invention is to provide an electronic control handle to solve the above-mentioned problems, as detailed below.

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

[0005] This utility model provides an electronic control handle, including a housing, an installation plate rotatably disposed inside the housing, a control lever hinged to the installation plate, a grip fixedly connected to the upper end of the control lever, a multi-function button fixedly connected to the grip, an arc-shaped toothed plate fixedly connected to the installation plate, an angle sensor fixedly connected inside the housing, and a gear fixedly connected to the input shaft of the angle sensor, the gear meshing with the arc-shaped toothed plate.

[0006] Using the aforementioned electronic control handle, pushing the joystick causes the arc-shaped gear plate to rotate via the mounting plate. The arc-shaped gear plate, in conjunction with the gears, drives the angle sensor. The angle sensor transmits an electrical signal to the ECU, which then drives the actuator to operate.

[0007] Preferably, the top of the housing has a movable groove, through which the upper end of the control lever passes.

[0008] Preferably, a label is provided on the upper side of the housing along the length of the movable groove to indicate the function corresponding to the direction of the joystick push.

[0009] Preferably, a rubber strip is fixedly connected to the inner wall of the movable groove to increase the friction between the control lever and the movable groove.

[0010] Preferably, the mounting plate has a groove that is adapted to the control lever, and the inner wall of the movable groove has a slot for engaging the control lever.

[0011] Preferably, the mounting plate is provided with a tension spring, and both ends of the tension spring are fixedly connected to the mounting plate, with the tension spring placed horizontally between the grooves.

[0012] Preferably, a rotating shaft is rotatably connected inside the housing, and the mounting plate is fixedly connected to the rotating shaft.

[0013] Preferably, a wiring terminal is fixedly connected to the bottom of the housing, and the angle sensor and the multi-function button are both electrically connected to the wiring terminal.

[0014] The beneficial effects are:

[0015] 1. The joystick drives the arc-shaped gear plate to rotate through the mounting plate. The arc-shaped gear plate and the gear can drive the angle sensor, so that the angle sensor transmits the electrical signal to the ECU. The ECU drives the actuator to run. The angle sensor can adjust the vector, so the control precision is higher. The addition of multi-function buttons can further improve the function of the joystick, meet various operation needs, reduce the complexity of operation, and improve operation efficiency.

[0016] 2. The rubber strip increases the friction between the control lever and the movable groove. The tension spring pushes the control lever closer to the rubber strip, increasing the friction between the control lever and the rubber strip and improving the stability of the control lever. This prevents the control lever from shifting due to vibrations during vehicle operation, avoids autonomous changes in the vehicle's operating state, and thus improves the safety of vehicle operation.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] See Figures 1-4 As shown, this utility model provides an electronic control handle, including a housing 1, an installation plate 13 rotatably disposed inside the housing 1, a control lever 2 hinged to the installation plate 13, a grip 3 fixedly connected to the upper end of the control lever 2, a multi-function button 4 fixedly connected to the grip 3, an arc-shaped toothed plate 10 fixedly connected to the installation plate 13, an angle sensor 12 fixedly connected inside the housing 1, and a gear 11 fixedly connected to the input shaft of the angle sensor 12, and the gear 11 meshing with the arc-shaped toothed plate 10;

[0026] The angle sensor 12 is existing technology, and its output can be changed through programming.

[0027] As an optional implementation, the top of the housing 1 is provided with a movable groove 6, and the upper end of the control lever 2 passes through the movable groove 6. The movable groove 6 is used to guide the movement trajectory of the control lever 2.

[0028] A label 16 is provided on the upper side of the housing 1 along the length of the movable groove 6 to indicate the function corresponding to the pushing direction of the control lever 2. The content of the label 16 can be customized according to the requirements, such as high speed and low speed, lifting and lowering, and forward and backward movement.

[0029] A rubber strip 7 is fixedly connected to the inner wall of the movable groove 6 to increase the friction between the control lever 2 and the movable groove 6. This can prevent the control lever 2 from shifting due to vibration during vehicle operation and avoid the vehicle's operating state from changing autonomously.

[0030] The mounting plate 13 has a groove 14 that is adapted to the control lever 2. The inner wall of the movable groove 6 has a slot 8 for engaging the control lever 2. Pushing the control lever 2 into the slot 8 can fix the control lever 2 and prevent the driver from operating it by mistake.

[0031] A tension spring 15 is provided on the mounting plate 13, and both ends of the tension spring 15 are fixedly connected to the mounting plate 13. The tension spring 15 is horizontally placed between the grooves 14. The tension spring 15 is used to push the control lever 2, so that the control lever 2 moves closer to the slot 8 and the rubber strip 7. On the one hand, it can prevent the control lever 2 from disengaging from the slot 8 when there is no manual operation. On the other hand, it can increase the friction between the control lever 2 and the rubber strip 7, thereby improving the stability of the control lever 2.

[0032] A rotating shaft 9 is rotatably connected inside the housing 1, and the mounting plate 13 is fixedly connected to the rotating shaft 9.

[0033] The bottom of the housing 1 is fixedly connected to the wiring terminal 5, and the angle sensor 12 and the multi-function button 4 are both electrically connected to the wiring terminal 5.

[0034] With the above structure, pushing the control lever 2 can drive the arc-shaped toothed plate 10 to rotate through the mounting plate 13. The arc-shaped toothed plate 10 and the gear 11 can drive the angle sensor 12. The angle sensor 12 transmits electrical signals to the ECU, and the ECU drives the actuator to run.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
