Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery operating panels, and in particular to an excavator controller operating panel. Background Art

[0002] The excavator controller is the core control system of the excavator. It receives signals from sensor feedback and control commands from the driver to perform real-time control of the excavator's engine, hydraulic system, transmission system and other parts, thereby realizing automation and optimized control of the excavator and improving the excavator's working efficiency, accuracy and safety. The controller operation panel is the core component of the excavator operation. It integrates a variety of function buttons to receive instructions from the operator and start or shut down the excavator engine. It allows the operator to select different working modes according to work requirements, such as standard mode, heavy digging mode, repair mode, etc., to optimize the performance and efficiency of the excavator. It is an important part of the normal operation and efficient operation of the equipment.

[0003] However, since most of the buttons on the existing excavator controller operating panel are made of integrated silicone keypads and independent keypads, when using integrated silicone keys, if the silicone keys are damaged, the entire silicone keypad needs to be disassembled and replaced to ensure the use of the operating panel, which is more troublesome. In addition, since the seal between the existing silicone keypad and the circuit board is mostly bonded together by glue, during the process of disassembling the silicone keypad, the bonding surface between the silicone keypad and the circuit board will be damaged to varying degrees, resulting in the silicone keypad being unable to be used again, causing a waste of resources. When using an independent keypad, there will be a certain gap between the independent keys and the operating panel, and dust and water can easily enter the operating panel from the gap to corrode the internal electrical components, affecting the service life of the operating panel. Moreover, the independent keys are easily detached from the operating panel due to scratches by foreign objects, affecting the operating experience of the operating panel.

[0029] In one embodiment, since a silicone cap 42 is mounted inside the sealing gasket 41 at a position corresponding to the key cap 32, when the silicone cap 42 is damaged, the closing plate 4 can be directly removed and the silicone cap 42 in the slot 411 on the sealing gasket 41 can be replaced, thereby avoiding the trouble of replacing the entire silicone key panel, reducing the waste of resources, and having strong practicality.

[0030] In one embodiment, when using the operation panel, the silicone cap 42 can be directly pressed to deform the silicone cap 42 and drive the key cap 32 located in its inner cavity to move downward in the connecting groove 401, so that the key ear 322 installed at the bottom of the key cap 32 slides downward on the outer wall of the limit rod 33 through the sliding hole 323 and presses the spring 34 to deform. At the same time, the key cap 32 in the downward displacement drives the pressing rod 321 installed in its inner cavity to move downward, so that the pressing rod 321 presses the key switch 31 on the key plate 3 to turn on the key switch 31. Finally, the silicone cap 42 is released to allow the key cap 32 and the pressing rod 321 to return to their original positions under the action of the elastic force of the spring 34. The operation of the operation panel can be completed, and instructions can be issued to the downward controller through the buttons on the operation panel to control the movement of the excavator, thereby ensuring the use of the operation panel.

The structure is simple, the operation is convenient, and it is conducive to the subsequent maintenance work.

[0032] The working principle of the present invention is: when assembling the operation panel, the circuit board 2, the key board 3, and the closing plate 4 can be sequentially mounted on the outer wall of the positioning rod 13 through the first through hole 201, the second through hole 301, and the third through hole 402, and then the lower shell 12 is snap-fitted and installed on the bottom of the upper shell 11 through the cooperation of the plug plate 121 and the slot 112, and then the fastening bolt 14 in the groove 123 is screwed, and the fastening bolt 14 is installed inside the positioning rod 13, and the nut of the fastening bolt 14 presses the lower shell 12 tightly against the bottom of the upper shell 11, so that the circuit board 2, the key board 3 and the closing plate 4 can be pressed tightly into the empty groove 101, and the sealing gasket 41 seals the gap between the closing plate 4 and the inner wall of the upper shell 11, and closes the key hole 111, so as to prevent dust and water from entering the interior of the operation panel through the gap between the key hole 111 and the silicone cap 42, thereby avoiding The situation in which dust and water enter the operation panel and cause the internal electrical components to be corroded and damaged occurs, which improves the sealing of the operation panel and extends the service life of the operation panel. At the same time, the closing plate 4 presses the silicone ear 421 at the bottom of the silicone cap 42 against the inner cavity wall of the upper shell 11 to limit the position of the silicone cap 42 and prevent the silicone cap 42 from detaching from the operation panel. This avoids the trouble of the silicone cap 42 falling off the operation panel and affecting the key operation due to being scratched by foreign objects, thereby ensuring the use of the operation panel. Moreover, when the silicone cap 42 is damaged, the closing plate 4 can be directly removed and the silicone cap 42 engaged in the card slot 411 on the sealing pad 41 can be replaced, thereby avoiding the trouble of replacing the entire silicone key panel and reducing the waste of resources. The structure is simple, the operation is convenient, and it is conducive to the subsequent maintenance work.
