Jinche Parts and accessories cover multiple automotive systems such as engines, transmissions, brakes, and steering. Their working principle is based on mechanical mechanics, materials science, and hydraulic/pneumatic control, achieving power transmission, motion conversion, or force transmission through precise structures. The following is an explanation of its working principle from the classification of core systems: 1. Engine system components: The core of energy conversion, the crank connecting rod mechanism. Piston: It moves back and forth in a straight line within the cylinder and pushes the connecting rod through the pressure in the combustion chamber

The flip shaft of a mobile phone is a core mechanical component that connects the main body of the phone with the flip part. It achieves the opening, closing, positioning and fixation of the flip through precise structural design. Its role is not only related to the basic usage functions, but also directly affects the durability, portability and user experience of the mobile phone. The following are the main functions and technical details of the flip hinge of a mobile phone

The Touchpad (Touchpad or Trackpad), as an input device that controls the pointer by sensing the movement of the finger, has been widely applied in multiple fields due to its intuitive operation, space-saving and convenient interaction features. Specifically, in the consumer electronics field: The core interactive tool of portable devices, the basic functions of laptops, replace the mouse: The touchpad controls the movement of the pointer through single-finger sliding, simulates the left mouse button with single-finger clicking, and simulates the right mouse button with two-finger clicking, meeting the needs of daily operations

The magnetic card case holder is an innovative accessory that combines magnetic technology, card case storage and mobile phone support functions. Its functions cover multiple dimensions such as daily use, scene adaptation and design optimization. Specifically, it is as follows: 1. Core functions: Convenient storage and stable support. Efficient card storage with multi-slot design It is equipped with 3 to 5 card slots, which can hold commonly used cards such as ID cards, bank cards and transportation cards, preventing cards from scattering or getting lost

The rotating shaft of a digital photo frame is a key component that connects the main body of the photo frame with the screen or support structure. Its core function is to achieve multi-angle adjustment and stable support of the photo frame through rotation or flipping, while also taking into account durability and user experience. The following is the specific function analysis: First, it achieves multi-angle adjustment, enhancing the flexibility of use. The screen Angle can be freely adjusted. The rotating shaft, through damping design or gear structure, allows users to adjust according to the light, viewing distance or desktop height

Due to their high precision, high efficiency and wide applicability, hardware lathe parts have been widely used in many fields. Specifically, in the field of electronics and electrical appliances, hardware lathe parts are used to manufacture micro connectors, shaft parts and springs (such as brush springs and switch springs) for products like mobile phones, cameras and computers, ensuring the stability of signal transmission and structural compactness. Its tolerance can be controlled within ±0.01 millimeters, meeting the strict precision requirements of electronic components.
