What is the mounting base for the front license plate of a car?
The front license plate mounting base refers to a base component fixed at the front of the vehicle to support and lock the front license plate (usually including a fixed base, screws, and rubber pads), or it directly refers to the reserved fixed position of the front license plate on the bumper; it is not a legally mandatory accessory, but the installation must be done in conjunction with a dedicated locking device.
Definition and Alias: Also known as license plate base, license plate holder, or locking base, it is the intermediate fixed structure connecting the license plate and the vehicle body. In some contexts, it also generally refers to the reserved installation hole area at the front of the vehicle.
Core Function: Provides stable support to prevent loosening and detachment, buffers vibrations to prevent scratches, and cooperates with the locking cap to achieve compliant anti-theft. It can also partially solve the problem of incompatible holes in imported vehicles.
Component Elements: Usually includes a plastic/metal base, dedicated bolts, nuts, and a locking cover with the license plate issuing authority's code (which must be consistent with the license plate's location).
Regulatory Points: If using a base/stand to assist in installation, the inner edge of the base must be greater than 5mm from the license plate characters, must not cover the white border or have decorative patterns, and must use a fixed structure that cannot be disassembled at will.
Installation Requirements: The front license plate should be located at the center of the vehicle or slightly to the right (in the direction of travel), and at least use 2 (usually 4) dedicated locking devices to tighten, ensuring horizontal and vertical alignment without deformation.
Note: The term "installation base" is not mandatory, but the license plate must be fixed in a compliant manner; the use of removable, advertising-laden, or character-occluding bases/stands is illegal and may result in demerit points and fines.
Core Function of the Front License Plate Mounting Base: To standardize the installation of the license plate, buffer vibrations to prevent damage, protect the vehicle paint, and assist in compliant anti-theft.
Main Function
Stable Fixation: Provides a standard installation interface to ensure that the license plate does not loosen or fall off in bumpy road conditions.
Buffer Protection: As an isolation layer between the license plate and the vehicle body, it absorbs vibrations and prevents the metal license plate from directly scratching the vehicle paint or deforming or scratching itself due to friction.
Compliant Installation: Cooperates with the locking screws to meet the mandatory requirements of traffic regulations for the firmness and visibility of license plate installation (for some models, without a base, it is difficult to install in a compliant manner).
Compatible Adaptation: Solves the problem of incompatible holes in imported vehicles and other non-standard holes with standard license plates, achieving precise alignment.
Auxiliary Anti-Theft: Cooperates with dedicated anti-theft locking caps/screws to increase the difficulty of disassembly and reduce the risk of license plate theft. Notes for Attention
Installation must follow the standards of the "Motor Vehicle License Plate of the People's Republic of China". If a decorative frame (often mistakenly called the base) is added, the inner edge of the frame must be more than 5mm away from the characters. It is strictly prohibited to cover the license plate characters or affect recognition. Otherwise, it is considered an illegal act.
If the front license plate mounting seat of the car is damaged, it must be immediately removed and a new base installed. It is strictly forbidden to directly hang it or use adhesive tape for temporary fixation. Otherwise, the license plate may fall off and be subject to violation.
Core handling plan
Must be replaced: The base is damaged and cannot provide stable support. The old part must be removed and a new base installed. It cannot be repaired and reused.
Compliance requirements: Installation must use the special anti-theft screws provided by the vehicle management office to ensure the license plate is flat, firm, and without any obstruction.
Risk warning: If the license plate is loose or falls off, it may be regarded as "not installing the license plate in accordance with regulations", facing the risks of fines, demerit points, and inability to pass the annual inspection.
