The function of the rear mounting bracket assembly for the car's auxiliary dashboard
The main function of the rear mounting bracket assembly for the car's auxiliary dashboard is to enhance the structural stability of the auxiliary dashboard, increase the installation strength, and support the fixed installation of larger or heavier equipment. According to multiple utility model patents and technical materials, its specific functions can be summarized as follows:
Improving overall rigidity and resistance to deformation: By connecting the originally independent left and right rear brackets through a bridge-type mechanism into a single unit, the rigidity and strength of the bracket assembly are significantly enhanced, preventing deformation caused by load or vibration.
Convenient installation and adaptability to different size components: This assembly usually comes with multiple sets of mounting plates (upper/lower mounting plates) and adjustable structures, enabling flexible matching of different-sized and-weighted auxiliary dashboards or the integrated equipment on them (such as air conditioning outlets, storage boxes, electronic control units, etc.).
Improving passenger comfort and handling stability: A stronger bracket structure helps reduce minor vibrations or abnormal sounds in the vehicle's dashboard area during driving, indirectly improving the NVH (noise, vibration, and harshness) performance of the entire vehicle.
Support for multi-functional integration: Some designs also combine air conditioning ducts, storage spaces, and other functional modules, ensuring the precise positioning and reliable connection of these components while providing structural support for the bracket.
In summary, this assembly is not only the "framework" of the auxiliary dashboard but also a key structural component that ensures the stable operation of the in-car human-machine interaction equipment.
When the rear mounting bracket assembly for the car's auxiliary dashboard malfunctions, it usually involves problems with the supporting structure or fixed components of the auxiliary dashboard assembly (i.e., the area below the center console). According to public information, such malfunctions may manifest as looseness, abnormal sounds, fractures, or functional failures.
Common fault manifestations
Structural loosening or abnormal sounds: During driving on bumpy roads, the auxiliary dashboard area emits clicking sounds or a vibrating sensation.
Decorative cover plates fracture: Such as cup holder sliding covers, handrail covers, etc., due to material fatigue or design flaws, they break .
Connection components loose: Screws, clasps of the fixing brackets loosen or fall off, causing overall shaking .
Function components fail: If the bracket integrates modules such as wireless charging or shift bases, there may be contact failure or inability to use. Possible reasons
Long-term vibration leads to fatigue damage: Continuous vibration during vehicle operation causes the material of the brackets (especially plastic or rubber parts) to age and crack.
Installation process issues: Manufacturing problems such as stamping defects or wear on the mold gap may result in insufficient initial strength of the brackets.
Poor compatibility with non-original factory parts: Using third-party substitutes may cause size or material mismatch, leading to loosening or fracture.
External force impact: Abrupt braking, collisions, or improper operations (such as forcibly turning the cover) can cause structural damage.
Suggested handling steps:
Preliminary inspection:
Observe if the auxiliary dashboard has obvious cracks, deformation, or missing components.
Gently shake the relevant area to determine if there is looseness or abnormal noise.
Simple repair:
If it is a loose screw, you can tighten it or replace the self-locking nut.
If it is a minor fracture but does not affect use, you can try using high-strength automotive-specific glue (such as 3M Structural Adhesive) for bonding.
Professional repair:
If the fracture is severe, affecting functionality or safety, it is recommended to replace the auxiliary dashboard cover assembly or the rear-mounted bracket assembly.
The replacement process usually requires disassembling the central control panel, air conditioning control unit, etc., and the engineering workload is large. It is recommended to operate at a 4S store or professional repair shop.
Preventive measures:
Avoid applying additional pressure or placing heavy objects on the auxiliary dashboard area.
Regularly check if the fasteners are loose, especially after driving for more than 50,000 kilometers.
