With the rapid development of large-scale machinery technology and the advancement of electronic control and automation technology, non-road machinery is gradually placing greater emphasis on driving experience and automated control.

[0003] Traditional off-road machinery (such as harvesters, excavators, and loaders) typically uses simple mechanical locks, which are mostly purely mechanical structures, cumbersome to operate, and lack ease of use. Because off-road machinery operates in extremely harsh environments, the exposed lock cylinders are easily clogged by foreign objects, and the lock cylinders are susceptible to contamination, jamming, and damage.

[0004] Traditional mechanical door locks have a single function for their handles, without any status indicators or interactive feedback, which is inconsistent with the intelligent image of modern devices.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a door handle assembly for an electronically controlled door lock. It upgrades the traditional purely mechanical door handle into an intelligent assembly that integrates electronic unlocking and mechanical emergency unlocking, improving the convenience of unlocking and enhancing the user experience. The hidden mechanical lock cylinder design reduces the probability of contamination and damage, and ensures the reliability of the emergency function.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A door handle assembly for an electronically controlled door lock includes a handle body, which consists of a central handle portion and two side fixing portions. One fixing portion houses a door handle button and a mechanical lock cylinder, while the other fixing portion has an NFC sensing area. The door handle button is sleeved on the outside of the mechanical lock cylinder body, with its inner end connected to a micro switch and a removable button cover installed on its outer end.

[0008] Furthermore, the handle body is fixed to the outside of the cab door in a horizontal direction, and rubber pads are installed at the connection points between the handle body and the cab door.

[0009] Furthermore, the micro switch is connected to the controller inside the door handle assembly.

[0010] Furthermore, the door handle button has a spring installed inside to return it to its original position.

[0011] Furthermore, the button cover has a pry slot for inserting a mechanical key.

[0012] Furthermore, the inner end of the mechanical lock cylinder is connected to the pull cable drive plate, which is hinged and rotated. The pull cable drive plate is connected to one end of the pull cable, and the pull cable drive plate is connected to the lock body through the pull cable.
