What is the assembly of mounting brackets installed in the middle of the car's auxiliary dashboard?
The central mounting bracket assembly installed in the middle of the car's auxiliary dashboard is a key structural component of the car's interior system. It is mainly used to support and fix the middle area of the auxiliary dashboard (also known as the middle channel), ensuring a secure installation, reducing shaking, and enhancing the perception quality of the vehicle's interior.
According to public information, this component has the following characteristics:
Function positioning:
Supporting the middle structure of the auxiliary dashboard and integrating the concealment and fixation of components such as the gearshift, handbrake, ECU, and HVAC.
Enhancing the overall installation strength, reducing lateral shaking, and improving the perception of interior quality by customers.
Some designs also take into account functions such as quick repair, split assembly, and buffer energy absorption.
Structural features (taking a typical patent as an example):
It often adopts a split connection structure, such as through arc-shaped frames, locking protrusions, and lock sleeves to achieve multiple fixations, facilitating local replacement.
Some designs include flipping components and positioning components, supporting the efficient flipping of dashboard components during maintenance.
Some integrate bridge-type connection mechanisms, connecting the left and right brackets as a whole to increase stiffness and versatility.
Technical trends:
Recent patents emphasize features such as quick repairability, impact force reduction protection, and adjustable installation positions to cope with assembly errors and improve after-sales efficiency.
The main function of the central mounting bracket assembly for the auxiliary dashboard installation is to support and fix the key components inside the auxiliary dashboard and enhance the overall structural stiffness and assembly stability. Based on the latest public information, its specific functions can be summarized as follows:
Support and fixation function: The central mounting bracket is used to connect the auxiliary dashboard body with the vehicle floor or surrounding structures (such as handbrake, ECU, HVAC ducts, etc.), ensuring these components remain in a stable position during driving.
Improving stiffness and NVH performance: By enhancing the structural strength of the bracket body, reducing deformation and shaking of the auxiliary dashboard under vehicle vibration or load, and improving the comfort and handling stability of the entire vehicle.
Integrating electrical/functional component installation: Some brackets are designed with dedicated installation slots or interfaces to fix low-frequency antennas (such as the PEPS system), lighting fixtures, sensors, etc., facilitating modular assembly and supporting platform-based development.
Optimizing space layout: Forming a storage space in the middle of the auxiliary dashboard, supporting the flexible placement of functional components such as elbow rest boxes, storage compartments, and phone racks, and achieving precise positioning through multiple installation brackets (such as front, middle, and rear brackets). In conclusion, this support structure is not only a load-bearing component, but also an important carrier for achieving functional integration, facilitating assembly, and enhancing passenger comfort.
The central mounting bracket assembly (also known as the middle channel mounting bracket or the middle guard bracket) is a key structural component that supports and fixes components such as the dashboard and the center console. Its faults usually manifest as abnormal noises, loosening, cracking, deformation, or instability of functional parts (such as the cup cover plate, wireless charging module).
According to public information, the common causes of this component's faults and the corresponding solutions are as follows:
Common Fault Causes
Pressing process defect: During the manufacturing process, improper flanging forming process can lead to tearing, skewing, especially at the hole type, side wall corner or the junction of the R arc and the wall neck.
Long-term vibration fatigue: The bumps and engine vibrations during vehicle driving cause the bracket to bear repeated loads, leading to the expansion of micro cracks until fracture.
Insufficient material or design strength: If the bracket's bending and shear strength is insufficient, or the mold guide is unstable, it is prone to plastic deformation or failure during use.
Assembly or repair damage: Improper operation when replacing the auxiliary dashboard decorative cover plate, air conditioning panel, etc., may cause the bracket latch to break or the supporting structure to be damaged.
Typical Fault Manifestations
Abnormal noises occur in the center console area (such as creaking or clicking sounds), especially when driving over bumpy roads;
The auxiliary dashboard decorative cover plate (such as the cup holder sliding cover plate) becomes loose, breaks, or cannot be reset;
The embedded components such as the wireless charging module, shift base, etc. shake or shift;
When disassembling, visible tearing, deformation, detachment of the rubber pad, or loosening of the connecting bolts of the bracket can be observed.
Suggested Handling Steps
Initial inspection: Observe if the auxiliary dashboard is obviously loose, noisy, or has visible cracks.
Refer to the maintenance manual: Confirm the bracket structure and disassembly process to avoid disassembly and causing secondary damage.
Professional diagnosis： It is recommended to go to a 4S store or a professional repair institution， and use a lift to check the connection status and fastening condition of the bracket.
Replace the original part： If the damage is confirmed， the original or compatible model of the bracket assembly should be replaced to ensure installation accuracy and safety.
