What is the rear mounting bracket assembly for the super-large dashboard of the car?
"The large-sized rear mounting bracket assembly for the automotive dashboard" is not a standard general term. It usually refers to a dedicated metal or engineering plastic bearing bracket assembly used to support, fix or connect the rear structure of large dashboard assemblies (such as curved screens,贯穿-type displays， etc.)， which is commonly seen in heavy-duty vehicles， commercial vehicles or highly integrated intelligent cabin models.
This component belongs to the internal structural parts of the dashboard assembly. It is located behind the dashboard (center console) and connects the vehicle body (such as the front panel， crossbeam or floor)， performing functions of bearing， positioning， shock absorption and stiffness support， rather than being used for external devices (such as phone brackets).
"Large-sized" usually corresponds to high integration， large size and heavy weight dashboard systems (such as integrated curved screens + HUD + passenger seat screen)， requiring strengthened rear fixation points to meet vibration， collision safety and assembly accuracy requirements.
In engineering practice， it is often referred to as "rear mounting bracket assembly for dashboard" or "rear installation bracket for dashboard"， as described in Zhengzhou Zhuoda Patent (CN224145771U)， which may include connection base， support frame， elastic snap， shading structure， etc.， to accelerate assembly and enhance stiffness.
Note the distinction： This is not a vehicle-mounted mobile phone/navigation bracket (belonging to aftermarket accessories)， but an original vehicle body-interior key connection component， commonly seen in Shagang (such as the accessory number 812w61701-6219) or high-end electric/ intelligent models.
If it involves repair or replacement， it is necessary to query according to the specific model number/accessory number (such as "812w61701-6219")， as the structure and adapted vehicle models are highly customized； the term "large-sized" in the general description is mostly a marketing or internal industry口径， without a unified industry definition.
If you are referring to a large rear-mounted display/device bracket that is aftermarket installed， it does not belong to "rear installation bracket assembly for dashboard"， but should be classified as "vehicle central control/dashboard installation bracket"； if it involves original structural components， it is necessary to provide the specific model and number to accurately identify.
The large-sized rear mounting bracket assembly for the automotive dashboard (usually referring to dashboard crossbeam or sub-frame type structural components) is mainly used to support the dashboard assembly， enhance vehicle stiffness， ensure collision safety， and integrate electrical/acoustic air conditioning pipeline routing.
Structural support： As the main installation base of the dashboard， it supports display screens， air conditioning outlets， airbag modules and other front cabin components， ensuring assembly accuracy and static stiffness.
Body stiffness contribution： Connected to the left and right A-pillars and front crossbeam， it forms part of the "front cabin skeleton"， enhancing torsional stiffness and NVH (noise vibration) performance.
Safety protection： In frontal collisions， it absorbs energy through controlled collapse to prevent dashboard intrusion into the passenger cabin and provide a counteracting support surface for airbag explosion.
Pipeline and system integration： The rear part often reserves channels or installation points for wiring， air ducts， brake lines， etc.， to achieve orderly layout of functional components.
Weight reduction and integration (such as magnesium/aluminum parts)： In high-end models， it replaces multiple stamped steel parts through structural topology optimization to reduce weight and enhance modularization.
Note： This component is not an aftermarket vehicle bracket (such as mobile phone/navigation bracket)， but an original vehicle body-interior main structural component， usually hidden behind the dashboard， not directly exposed. If referring to "rear-mounted large bracket"， it needs to be determined based on the specific model or modification scenario， but the term "large-sized rear mounting bracket assembly for dashboard" in the standard description usually refers to the above-mentioned structural crossbeam.
