Description

Damped control handle assembly Technical Field

[0001] This utility model relates to the field of harvester control handle technology, specifically to a damped control handle assembly. Background Technology

[0002] With the continuous development of agricultural mechanization, the technology of modern harvesters is constantly improving, especially with the increasing application of electronic control and automated operation. In existing harvesters, the handle, as one of the important control components, is usually used to adjust key parameters during the operation of the equipment.

[0003] Existing handle designs generally lack effective damping systems, resulting in poor handling feel, reduced operator comfort, and negatively impacting work efficiency and experience. Furthermore, their response to operator feedback is inaccurate, making operation too stiff and difficult to control precisely. Moreover, harvesters face frequent vibrations and external impacts during operation, a factor that current handle designs fail to adequately consider, leading to poor handle performance and stability.

[0004] In summary, there is an urgent need for a new type of damping control handle assembly to improve control precision, comfort, and stability in order to adapt to the complex working environment of harvesters. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a new type of damping control handle assembly to improve control precision, comfort and stability, so as to adapt to the complex working environment of the harvester.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] This utility model provides a damped control handle assembly, including a handle push rod, a base, and a bracket. The upper end of the handle push rod is provided with a handle grip, and the lower end of the handle push rod is rotatably connected to the base via a first rotating shaft. A damper is also provided between the lower end of the handle push rod and the base. The handle push rod can overcome the resistance of the damper and rotate around the first rotating shaft relative to the base under the action of external force. The base is rotatably connected to the bracket via a second rotating shaft. The first rotating shaft and the second rotating shaft are both horizontally arranged and perpendicular to each other.

[0008] The beneficial effects of this utility model are:

[0009] By employing this invention, a damper between the lower end of the handle push rod and the base can feed back the rotation of the handle push rod around the first axis to the handle push rod in the form of resistance. This facilitates the operator's judgment of the operating stroke, improves operating comfort, and enables precise control. At the same time, the resistance of the damper can withstand vibration and external impact, improving handling performance and stability. Furthermore, the superposition of the movements of the first and second axes enables the handle push rod to perform a complex Z-shaped movement, providing good adaptability.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the lower end of the handle push rod is fixedly connected to the first rotating shaft, and the first rotating shaft is rotatably connected to the base; the first rotating shaft is connected to the middle part of the damper, and the outer periphery of the damper is connected to the base.

[0012] The first rotating shaft can be manufactured integrally with the lower end of the handle push rod. The damper is installed along the axis of the first rotating shaft, which is convenient to install and has good stability.

[0013] Furthermore, the damper is a disc rotation damper, the disc part of which is connected to the base by bolts, and the end of the first rotating shaft and the central hole of the disc rotation damper are rectangular in shape and size and fit together.

[0014] It is easy to assemble and disassemble. The first rotating shaft rotates synchronously with the central hole of the disc rotation damper, which provides high accuracy in feedback resistance and facilitates precise control.

[0015] Furthermore, a module mounting cavity is provided on one side of the base, and a programmable control module and a Hall sensor are provided in the module mounting cavity. The Hall sensor is electrically connected to the programmable control module. A magnet is provided on the rotating shaft, and the Hall sensor can monitor the changes in the magnetic field of the magnet and feed them back to the programmable control module.

[0016] When the handle push rod drives the first rotating shaft to rotate, the Hall sensor monitors the change in the magnetic field of the magnet and feeds it back to the programmable control module, thereby enabling precise monitoring of the handle's motion state and position. Subsequently, the programmable control module can generate corresponding mechanical control signals to control external devices, achieve precise control of the equipment, and ensure accurate operation and real-time response.

[0017] Furthermore, the second rotating shaft has two sections, which are located on opposite sides of the base.

[0018] The second pivot does not occupy the space near the middle of the first pivot, avoiding interference between the first pivot or the handle push rod and the second pivot; and it can symmetrically constrain the opposite sides of the base, resulting in good stability.

[0019] Furthermore, the second rotating shaft is fixedly connected to the base, and the second rotating shaft is rotatably connected to the bracket through a bearing.

[0020] Easy to install, with good stability of the base; at the same time, the bearings can effectively reduce friction during rotation, making the handle push rod rotate more smoothly and reducing wear on the second rotating shaft during long-term use, thus improving the stability of the handle.

[0021] Furthermore, the handle push rod is provided with a connecting support plate in the middle, and the connecting support plate is provided with a through hole in the middle.

[0022] It is easy to connect to external mechanical components such as pull cables, and can transmit the movement of the handle push rod to external equipment through the pull cable. It has a compact structure and good flexibility.

[0023] Furthermore, the handle grip is horizontally arranged in an olive shape, and a connecting sleeve is provided on the lower side of the handle grip, which is sleeved on the upper end of the handle push rod; one side surface of the handle grip and one side surface of the connecting sleeve form a smooth arc transition, and the other side of the handle grip protrudes from the other side of the connecting sleeve and forms an obtuse angle transition.

[0024] The ergonomic design optimizes the comfort of the handle head and reduces operator fatigue during prolonged use.

[0025] Furthermore, the handle grip is also provided with a groove, and an electronic control button is provided in the groove.

[0026] During installation, the electric control button is electrically connected to the external equipment, making it easy to control the external equipment, such as controlling the lifting and lowering of the header or reel, and the operation is convenient.

[0027] Furthermore, the handle grip is also provided with an electronic control integrated cavity, and a button-type electronic control device is provided in the electronic control integrated cavity. The control end of the button-type electronic control device faces and contacts the electronic control button, and the electronic control button is an elastic sealing button. The handle grip is also provided with a removable cover, which can be used to seal the electronic control integrated cavity.

[0028] This design allows for easy encapsulation of push-button electronic control devices within the handle grip, enhancing protection against liquids and dust entering the devices and facilitating routine maintenance. Attached Figure Description

Detailed Implementation

[0035] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0036] This utility model is shown in Figures 1-4.

[0037] This utility model provides a damped control handle assembly, including a handle push rod 1, a base 3, and a bracket 4. The upper end of the handle push rod 1 is provided with a handle grip 2, and the lower end of the handle push rod 1 is rotatably connected to the base 3 through a first rotating shaft 5. A damper is also provided between the lower end of the handle push rod 1 and the base 3. The handle push rod 1 can overcome the resistance of the damper and rotate around the first rotating shaft 5 relative to the base 3 under the action of external force. The base 3 is rotatably connected to the bracket 4 through a second rotating shaft 6. The first rotating shaft 5 and the second rotating shaft 6 are both horizontally arranged and perpendicular to each other.

[0038] principle:

[0039] During installation, the handle push rod 1 can be connected to external components such as pull cables via an external structure such as a support plate, and the bracket 4 is fixed to the frame of the harvester. The operator holds the handle grip 2, which can control the handle push rod 1 to rotate around the first rotating axis 5 relative to the base 3, and control the handle push rod 1 and the base 3 to rotate around the second rotating axis 6 relative to the bracket 4 simultaneously. The superposition of the movements of the first rotating axis 5 and the second rotating axis 6 realizes the complex Z-shaped movement of the handle push rod 1.

[0040] The handle push rod 1 can rotate relative to the base 3 around the first rotating shaft 5 under the action of external force, overcoming the resistance of the damper. This can be achieved in two configurations: the lower end of the handle push rod 1 is fixedly connected to the first rotating shaft 5, the first rotating shaft 5 is rotatably connected to the base 3, the first rotating shaft 5 is connected to the middle of the damper, and the outer periphery of the damper is connected to the base 3; or the lower end of the handle push rod 1 is rotatably connected to the first rotating shaft 5, the first rotating shaft 5 is fixedly connected to the base 3, the first rotating shaft 5 is connected to the middle of the damper, and the outer periphery of the damper is connected to the handle push rod 1. When the handle push rod 1 rotates around the first rotating shaft 5, it needs to overcome the resistance of the damper. The reaction force of the resistance is fed back to the operator's hand, allowing the operator to judge the operating stroke by feeling the start time and magnitude of the resistance, thus improving operating comfort and facilitating precise control. Simultaneously, the resistance of the damper can also withstand the vibrations and external impacts faced by the harvester during operation, improving handling performance and stability.

[0041] By employing this utility model, the damper between the lower end of the handle push rod 1 and the base 3 can feed back the rotation of the handle push rod 1 around the first rotating shaft 5 to the handle push rod 1 in the form of resistance, making it easier for the operator to judge the operating stroke, improving operating comfort, and facilitating precise control; at the same time, the resistance of the damper can withstand vibration and external impact, improving control performance and stability; in addition, the superposition of the movements of the first rotating shaft 5 and the second rotating shaft 6 realizes the complex Z-shaped movement of the handle push rod 1, which has good adaptability.

[0042] Furthermore, the lower end of the handle push rod 1 is fixedly connected to the first rotating shaft 5, and the first rotating shaft 5 is rotatably connected to the base 3; the first rotating shaft 5 is connected to the middle part of the damper, and the outer periphery of the damper is connected to the base 3.

[0043] The first rotating shaft 5 can be integrally manufactured with the lower end of the handle push rod 1. The damper is installed along the axis of the first rotating shaft 5, which is convenient to install and has good stability.

[0044] Furthermore, the damper is a disc-shaped rotating damper 7. The disc part of the disc-shaped rotating damper 7 is connected to the base 3 by bolts. The end of the first rotating shaft 5 and the central hole of the disc-shaped rotating damper 7 are rectangular in shape and size and fit together.

[0045] It is easy to assemble and disassemble. The first rotating shaft 5 rotates synchronously with the central hole of the disc rotation damper 7, and the feedback resistance is highly accurate, which facilitates precise control.

[0046] Furthermore, as shown in Figure 4: a module mounting cavity 8 is provided on one side of the base 3, and a programmable control module and a Hall sensor are provided inside the module mounting cavity 8. The Hall sensor is electrically connected to the programmable control module; a magnet is provided on the rotating shaft, and the Hall sensor can monitor the change in the magnetic field of the magnet and feed it back to the programmable control module.

[0047] Preferably, the programmable control module is a PCM board. The programmable control module is also provided with an external connector 9 for connecting external devices, and the external connector 9 extends out of the module mounting cavity 8.

[0048] Note: The Hall sensor monitors and feeds back changes in the magnetic field, which is the original function of the Hall sensor. The programmable control module that receives the feedback signal can also be a controller. The specific type can be selected according to the controlled equipment. This is existing technology.

[0049] When the handle push rod 1 drives the first rotating shaft 5 to rotate, the Hall sensor monitors the change in the magnetic field of the magnet and feeds it back to the programmable control module, thereby enabling precise monitoring of the handle's motion state and position. Subsequently, the programmable control module can generate corresponding mechanical control signals to control external devices, achieve precise control of the equipment, and ensure accurate operation and real-time response.

[0050] Furthermore, as shown in Figures 1-2: the second rotating shaft 6 has two sections, which are located on opposite sides of the base 3 respectively.

[0051] The second pivot 6 does not occupy the space near the middle of the first pivot 5, thus avoiding interference between the first pivot 5 or the handle push rod 1 and the second pivot 6; and it can symmetrically constrain the relative sides of the base 3, resulting in good stability.

[0052] Furthermore, the second rotating shaft 6 is fixedly connected to the base 3, and the second rotating shaft 6 is rotatably connected to the bracket 4 through a bearing.

[0053] Easy to install, the base 3 has good motion stability; at the same time, the bearing can effectively reduce friction during rotation, making the handle push rod 1 rotate more smoothly, reducing the wear of the second rotating shaft 6 during long-term use, and improving the stability of the handle.

[0054] Furthermore, the middle part of the handle push rod 1 is also provided with a connecting support plate 10, and the middle part of the connecting support plate 10 is provided with a through hole.

[0055] It is easy to connect to external mechanical components such as pull cables, and can transmit the movement of the handle push rod 1 to external equipment through the pull cable. It has a compact structure and good flexibility.

[0056] Furthermore, the handle grip 2 is horizontally arranged in an olive shape, and a connecting sleeve 11 is provided on the lower side of the handle grip 2. The connecting sleeve 11 is sleeved on the upper end of the handle push rod 1. One side surface of the handle grip 2 and one side surface of the connecting sleeve 11 are smoothly transitioned in an arc shape, and the other side of the handle grip 2 protrudes from the other side of the connecting sleeve 11 and forms an obtuse angle transition.

[0057] The ergonomic design optimizes the comfort of the handle head and reduces operator fatigue during prolonged use.

[0058] Furthermore, the handle grip 2 is also provided with a groove 12, and an electronic control button 13 is provided in the groove 12.

[0059] Preferably, the groove 12 is provided at one end and one side of the handle grip 2.

[0060] During installation, the electric control button 13 is electrically connected to the external equipment, making it easy to control the external equipment, such as controlling the lifting and lowering of the header or reel, and is easy to operate.

[0061] Furthermore, the handle grip 2 is also provided with an electronic control integrated cavity, and a button-type electronic control device is provided in the electronic control integrated cavity. The control end of the button-type electronic control device faces and contacts the electronic control button 13. The electronic control button 13 is an elastic sealing button. The handle grip 2 is also provided with a removable cover 14, which can be used to seal the electronic control integrated cavity.

[0062] Note: Push-button type electronic control devices can be push-button switches, etc., with the control terminal being the button; or they can be push-button integrated boards, with the control terminal being the button. The cover 14 and the handle grip 2 can be connected by screws.

[0063] This design facilitates the encapsulation of push-button electronic control devices within the handle grip 2, enhancing protection against liquids and dust entering the push-button electronic control devices and simplifying routine maintenance.
