Description

Technical Field

[0001] The present invention relates to the technical field of automobile interior structure, and in particular to an enveloping main and auxiliary instrument and a fixing method thereof. Background Art

[0002] With the evolving design concepts of new energy vehicles and traditional fuel-powered vehicles, more and more models are adopting asymmetrical instrument panel trim structures. Existing instrument panel trims are typically integrated, single-layer structures, resulting in a significant height in the Z-direction (vertical). This is primarily due to the need to accommodate functional modules such as air ducts, air ducts, the passenger airbag, and mid-range speakers, which in turn consume this height. However, this excessive Z-direction height not only compresses the passenger's legs and visual space in front of them, but also creates a sense of visual and psychological oppression, particularly for the passenger seat.

[0003] Furthermore, due to the single-layer instrument panel design, its X-direction (horizontal) length is short and lacks lateral extensibility, resulting in inefficient space utilization in the passenger compartment. Existing technologies often only feature a glove box for storing miscellaneous items, lacking a top-accessible storage structure. This fails to meet user needs for electronic devices such as tablets. In today's fast-paced world, passengers, especially children, often use tablets for writing, studying, and other tasks while parked or waiting. However, the traditional short and tall instrument panel structure clearly cannot support such work or study scenarios.

[0004] The single-layer structure of the main and auxiliary instrument panels lacks a well-defined internal space partition, making it difficult to balance functional integration and space optimization. This results in limited storage space and volume, as well as a lack of a rational functional layout. This leads to inconvenient storage, awkward access, and a poor overall user experience, severely impacting both the practicality of the vehicle's interior and passenger comfort.

[0005] Therefore, an enveloping main and auxiliary instrument and a fixing method thereof are proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The present invention aims to provide an embracing main and auxiliary instrument and a fixing method thereof, so as to solve or improve the above-mentioned technical problems that the existing main and auxiliary instrument panels mostly adopt a single-layer structure, have the problems of large Z-direction height, short X-direction length, single functional layout, insufficient storage space, etc.

[0007] In view of this, a first aspect of the present invention is to provide an enveloping main and auxiliary instrument.

[0008] A second aspect of the present invention is to provide a fixing method.

[0009] A first aspect of the present invention provides an enveloping main and auxiliary instruments and an instrument panel trim, wherein the instrument panel trim adopts a double-layer table top structure, and the instrument panel trim includes a front table top structure close to the front end of the vehicle along the vehicle X direction and a rear table top structure away from the front end of the vehicle; the inner cavity of the front table top structure is used to set vehicle functional components, and the end of the vehicle functional component passes through the front table top structure and extends to the vehicle cab, so as to be arranged in sequence along the circumferential direction of the vehicle cab and form a first enveloping structure; the vehicle functional components include a main instrument; the inner cavity of the rear table top structure is used to set vehicle interactive components, and the end of the vehicle interactive component passes through the rear table top structure and extends to the vehicle cab, so as to be arranged in sequence along the circumferential direction of the vehicle cab and form a second enveloping structure; the vehicle interactive components include a plurality of flip-up storage components and auxiliary instruments.

[0010] The second aspect of the present invention provides a fixing method, comprising the following steps: assembling the instrument panel trim in a vehicle cab, and dividing the inner cavity of the front table structure and the inner cavity of the rear table structure along the vehicle X direction; dividing the vehicle functional components and the vehicle interactive components according to the functions of the vehicle parts pre-installed inside the instrument panel trim; installing the vehicle functional components in the inner cavity of the front table structure and installing the vehicle interactive components in the inner cavity of the rear table structure along the vehicle Z direction or the vehicle Y direction; in the vehicle Y direction, the part of the vehicle functional components located in the vehicle cab is formed into a first encircling structure, and the part of the vehicle interactive components located in the vehicle cab is formed into a second encircling structure; along the vehicle Z direction and the vehicle X direction, the second encircling structure is arranged close to the driver and co-driver relative to the first encircling structure.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The front platform structure carries the vehicle's functional components and is on the upper layer, while the rear platform structure carries the vehicle's interactive components and is on the lower layer. The two layers form a "high in front, low in the back" stepped profile in the Z direction. The driver and co-pilot's view of the front is no longer obstructed by heavy obstacles, and the vertical distance between the head and the dashboard is increased, which can significantly alleviate the sense of oppression and field of vision brought by the traditional single-layer dashboard.

[0012] Functional components are arranged in sequence around the cab to form a first encircling structure, and interactive components are arranged in sequence around the cab to form a second encircling structure. The two encircling belts are layered up and down and echo each other front and back, creating an atmospheric cockpit with both visual wrapping and operational encirclement for the front passengers.

[0013] Through multiple flip-top storage components, storage is layered in the YZ directions, which can accommodate small items, tablet computers, document cooling and heating boxes and other items of various sizes. Each flip-top opening faces away from the front end of the vehicle, and the opening direction is consistent with the direction of the passenger's movement, making it easy to take out items even when operating blindly and safe to close.

[0014] Functional components are concentrated near the front of the vehicle, and the layout paths of the air outlets, speakers and airbags are short and straight, with low airflow loss and good sound field directionality; interactive components are close to the passenger end and isolated from the upper structure to avoid heat, noise and vibration crosstalk, thereby improving storage stability and multimedia experience quality.

[0015] Additional aspects and advantages of embodiments according to the present invention will become apparent in the following description or may be learned through practice of embodiments according to the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] See also Figure 1-Figure 4 , the following describes an enveloping main and auxiliary instrument and a fixing method thereof according to some embodiments of the present invention.

[0021] The embodiment of the first aspect of the present invention provides an enveloping master and slave instrument. In some embodiments of the present invention, such as Figure 1-Figure 3 As shown, the wraparound main and auxiliary instruments include an instrument panel trim 1, which adopts a double-layer table structure and includes a front table structure 101 close to the front end of the vehicle along the vehicle X direction and a rear table structure 102 away from the front end.

[0022] The inner cavity of the front table structure 101 is used to set vehicle functional components. The ends of the vehicle functional components pass through the front table structure 101 and extend to the vehicle cab, so as to be arranged in sequence along the circumference of the vehicle cab and form a first encircling structure; the vehicle functional components include a main instrument 2.

[0023] The inner cavity of the rear table structure 102 is used to set up vehicle interactive components. The ends of the vehicle interactive components pass through the rear table structure 102 and extend to the vehicle cab, so as to be arranged in sequence along the circumference of the vehicle cab and form a second encircling structure; the vehicle interactive components include multiple flip-top storage components and an auxiliary instrument 3.

[0024] The present invention provides an enveloping main and auxiliary instrument 3. The enveloping main and auxiliary instrument 3 introduces a double-layer table structure into the instrument panel trim 1 to achieve layered layout and coordinated integration of vehicle functional components and interactive components in space and function, thereby significantly improving the problems of traditional instrument panel structures in terms of oppression in passenger space, unreasonable distribution of functional areas, and insufficient storage and operation convenience. The instrument panel trim 1 is constructed as a composite structure with front and rear space partitions. It is provided with a front platform structure 101 near the front end of the vehicle and a rear platform structure 102 away from the front end along the vehicle X direction. The front platform structure 101 serves as the functional bearing area of ​​the entire instrument panel system. Its internal structure is designed for the integrated installation of functional components closely related to the vehicle's operating status, including but not limited to the instrument cluster, mid-range speakers, air conditioning ducts, defrost ducts and passenger airbags. The ends of these functional components extend from the inner cavity into the vehicle cockpit space through structural openings or grooves, so that the front platform forms a first enveloping structure that is continuously distributed from left to right in the vehicle width direction and creates a wrapping visual effect relative to the driver. While improving functional concentration and visual consistency, it creates an enveloping experience that naturally transitions from functional information to occupant perception.

[0025] Opposite to the functional layer formed by the front table structure 101 is the rear table structure 102 located behind it. This structure serves as an interactive function integration area, and its internal space is used to arrange operational or storage components that have a closer interaction with the occupants, including an upper storage box, a lower glove box 7, a driver storage box 5, a sub-instrument 3 display screen, an audio host and other structural units. These components also pass through the inner cavity of the rear table structure 102 through corresponding openings, flip covers or panel slots, extend and are exposed in front of the occupants in the vehicle cockpit space, so that the rear table is arranged in sequence along the transverse direction of the vehicle in the direction of the driver and co-pilot passengers into an interactive component belt that is wrapped around the interior cabin, thereby constructing a second enveloping structure, which, together with the front table structure 101, encloses a left-right symmetrical, front-to-back nested enveloping instrument space with obvious layering and spatial tension.

[0026] It's worth noting that this dual-layer structure not only significantly reduces the overall height of a traditional instrument panel in the Z direction, alleviating the sense of oppression between the front passenger's face and the instrument panel, but also frees up more horizontal space for storage and interaction through functional partitioning in the X direction. This creates a usable upward storage platform on the passenger side for the first time, meeting passengers' needs for convenient office work and information processing while waiting in line or on long journeys. Furthermore, the front-to-back arrangement of functional and interactive components facilitates logical wiring separation and simplifies the installation process. This avoids the problem of stacking functional modules and interfering with layout paths found in traditional single-layer integration solutions, improving overall assembly precision and system stability.

[0027] In summary, by introducing a double-layer tabletop structure of a front functional layer and a rear interactive layer into the same instrument panel trim 1, and arranging the two in a symmetrical, front-high-rear-low arrangement around the passenger space, the front tabletop, on the one hand, concentrates functional components that are important to vehicle operation and have strict installation requirements, such as air conditioning ducts, speakers, airbags, and instrument clusters, in a high-rise area near the front end, so that their air outlets, sound source ports, and information display surfaces are continuously arranged in the same visual strip, which not only optimizes the airflow path and acoustic effects, but also ensures the intuitiveness and safety of reading driving information. On the other hand, the rear tabletop is embedded with multiple flip-top storage components and a sub-instrument 3 display device in the low-rise area in front of the passengers. Combined with the horizontally extended upper cover / flip-top design, it releases a stable support surface for tablet computer placement, children's writing, or temporary office work, significantly improving the interaction convenience and scene adaptability on the passenger and driver sides. The two-layer structure, respectively responsible for operational output and human-machine interface storage, effectively reduces the Z-axis thickness of a traditional single-layer instrument panel due to stacked functions, achieving a high-front-low-rear design. Simultaneously, a longer X-axis surface and storage layout are created, alleviating visual congestion and increasing storage volume. This structural decoupling allows for clearer layout of wiring, ducting, and support components, modularizing the assembly process and improving manufacturing tolerances. This also optimizes vehicle NVH and safety restraints. Ultimately, the wraparound main and auxiliary instrument clusters create a cabin atmosphere that blends comfort and layering, balancing information display, climate control, storage, and entertainment. This reduces integration complexity and improves reliability, enhancing the overall visual, tactile, and operational experience for occupants, fully meeting the diverse requirements of modern new energy vehicles and high-end passenger vehicles for space quality, intelligent interaction, safety, and comfort.

[0028] In any of the above embodiments, the inner cavity of the front platform structure 101 and the inner cavity of the rear platform structure 102 are arranged in layers along the X-direction of the vehicle.

[0029] The first encircling structure is located above the second encircling structure along the Z direction of the vehicle.

[0030] The vehicle functional component is located in front of the vehicle interactive component along the vehicle X direction.

[0031] In this embodiment, the inner cavity of the front platform structure 101 and the inner cavity of the rear platform structure 102 are arranged in a front-to-back layer along the vehicle X direction, thereby making the two layers of space both continuous and separated from each other in horizontal projection: the front platform structure 101 is dedicated to accommodating the functional components of the vehicle. Its interior first receives the air conditioning blower duct 8, defrost air duct, mid-range speaker, tweeter, passenger airbag assembly and other devices that are of core significance to vehicle driving safety and driving experience. The ends of these functional components are connected through corresponding air guides and acoustic holes. Or the airbag opening passes through the outer surface of the front table, and surrounds the driver from left to right to form a first encircling structure; at the same time, the inner cavity of the rear table structure 102 is specially arranged with vehicle interactive components, including the upper storage box assembly 6, the lower glove box 7, the driver storage box 5, the auxiliary instrument 3 display device and the audio host, etc., to provide the passengers with commonly used human-computer interaction and item storage functions. The flip cover, drawer or display interface of these interactive components also goes beyond the outer surface of the rear table, and surrounds the passengers in the horizontal direction of the vehicle to form a second encircling structure.

[0032] Since the first encircling structure is located above the second encircling structure along the vehicle's Z direction, when the driver and co-pilot enter the cockpit, the first thing that catches their eye is the visual guidance and air streamlines provided by the instrument cluster information area and symmetrical air vents on the upper level, followed by the interactive storage and entertainment area on the lower level. The vertical visual difference and functional progression effectively reduce the oppressive feeling of the traditional single-layer instrument panel in the Z direction, and create a stepped contour with high front and low back through high and low partitions, thereby widening the occupants' forward field of view.

[0033] Furthermore, the vehicle's functional components are positioned in front of its interactive components along the vehicle's X-axis, placing them directly close to the front end. This shortens the air duct length and reduces fluid loss, while also placing the airbag closer to the crumple zone, improving deployment response speed. Interactive components are positioned closer to the occupants, allowing for storage and retrieval, touchscreen operations, and information viewing without changing the normal sitting posture, significantly improving ergonomics. This spatial topology creates a natural upper and lower cavity between the two-layered countertops, allowing for independent positioning of air conditioning ducts, wiring harnesses, and reinforcement beams, preventing entanglement and improving assembly accessibility and subsequent maintenance. Furthermore, the front-to-back layering provides structural support for expansion scenarios such as a temporary flat support surface and a constant-temperature heating and cooling box on the passenger side.

[0034] In any of the above embodiments, the rear platform structure 102 includes a first upper panel 1021 , a left lower guard plate assembly 1022 and a glove box assembly 1023 .

[0035] The first upper panel 1021 is connected to the front mesa structure 101 .

[0036] The left lower guard plate assembly 1022 and the glove box assembly 1023 are assembled to the lower part of the first upper panel 1021, and the left lower guard plate assembly 1022 and the glove box assembly 1023 and the first upper panel 1021 form the inner cavity of the rear table structure 102; and the vehicle interactive components also include a steering wheel assembly 4 that passes through the connection between the left lower guard plate assembly 1022 and the first upper panel 1021.

[0037] In this embodiment, the rear table structure 102 is collaboratively composed of three major components: a first upper panel 1021, a left lower guard plate assembly 1022, and a glove box assembly 1023: the first upper panel 1021 is connected to the front table structure 101 on the horizontal plane at multiple points using slots / studs / reinforcement beams to achieve front-to-back rigid penetration, so that the double-layer table forms an integrated continuous appearance in terms of force and shape; at the same time, the lower edge of the first upper panel 1021 extends downward in a stepped fold, extending positioning holes and snap-in grooves matching the left lower guard plate assembly 1022 and the glove box assembly 1023 to the driver's side and the co-pilot's side respectively. The left lower guard plate assembly 1022 and the glove box assembly 1023 are inserted and locked into these positioning interfaces from bottom to top during the assembly process, and the three together form a rear table structure 102 inner cavity with ample depth at the bottom.

[0038] This inner cavity is dedicated to the layout of interactive functional parts and wiring brackets. The front area near the driver's side is provided with curved side walls by the left lower guard plate assembly 1022, and the driver's storage box 5 and the hand switch / spring return mechanism are placed inside; the middle part is used by the lower surface of the first upper panel 1021 as the top plate, on which the audio host and the auxiliary instrument 3 display device are mounted; the rear area near the co-pilot side is formed by the glove box assembly 1023 shell to form a closed box body, which is used to accommodate the lower-opening glove box 7 cavity with a motor, latch, and pull rope control. The steering wheel assembly 4 passes through the steering column and through the prefabricated annular reinforcement hole at the junction of the left lower guard plate assembly 1022 and the first upper panel 1021. The hole is structurally covered by the folded edges of two guard plates and matched with a metal bushing, which not only ensures the stiffness of the steering wheel when the lateral torque is transmitted to the vehicle body frame, but also maintains a small height difference between the steering wheel multi-function switch panel and the upper surface of the first upper panel 1021, ensuring that there is no interference between the steering operating hand diameter and the upper table surface; at the same time, a wiring harness routing groove is left between the outer sleeve of the steering column and the side wall of the inner cavity, which can directly introduce the steering wheel switch signal line into the rear inner cavity, and then guide it to the audio host or body controller through the wiring harness bridge below the first upper panel 1021, so as to shorten the wiring harness.

[0039] Since the left lower guard plate assembly 1022 and the glove box assembly 1023 are arranged symmetrically in a mirror-image manner at the bottom of the first upper panel 1021, the appearance of the rear table top presents a smoothly wrapped and horizontally extended arc belt, which visually forms a double-layer embracing effect with the front table top functional belt located above it, which is dislocated up and down and echoes from front to back; in terms of structure, the guard plates and glove box on both sides respectively play the role of lower edge sealing and lateral vibration isolation. Combined with the bridge effect of the upper panel itself, the overall rear table top has good torsional stiffness and low-order modal control performance.

[0040] In any of the above embodiments, the flip-top storage components are respectively a driver storage box 5 located in the left lower guard plate assembly 1022 , an upper-opening storage box assembly 6 located in the first upper panel 1021 , and a lower-opening glove box 7 located in the glove box assembly 1023 .

[0041] In this embodiment, three flip-top storage components are precisely arranged in the interactive layer of the rear platform structure 102 according to the principle of left-right symmetry and upper-lower stratification of the vehicle: The driver storage box 5 located at the lower inner edge of the left lower guard plate assembly 1022 is arranged in the form of a lower hinge and an upper handle. When the driver extends his hand down to near his knee in a normal sitting position, he can naturally touch the handle switch; after lightly pressing the handle, the return spring drives the handle to disengage from the locking boss, and the storage box smoothly opens around the long flip axis located at the lower edge toward the driver. The flip angle is precisely limited by the combination of the arc motion groove and the limit block on both sides, which not only avoids over-travel colliding with the calf, but also ensures that internal debris does not slide out due to excessive tilt, realizing one-handed quick retrieval and safe closure under "blind operation" conditions.

[0042] The upper-opening storage box assembly 6 located on the lower table in the center of the first upper panel 1021 is supported on the lower surface of the upper panel by a hidden hinge and a double-sided spring, rack, and gear damping mechanism. After the occupant lightly presses the trigger switch on the front edge of the upper cover, the left and right sets of latches retreat synchronously, and the upper cover swings upward along the Z direction of the vehicle under the drive of the spring force. The rack and gear pair provide controlled damping during the entire opening stroke, so that the upper cover is lifted to the set limit angle at a predictable speed and hovers. After opening, its inner bottom wall and the upper surface of the first upper panel 1021 form an integrated horizontal platform, which can be used to stably place a tablet computer, handwriting notebook or mobile keyboard; when closing, lightly press the upper cover, and the lower edge boss is pressed back into the latch lock position, realizing a smooth interactive experience of "one press to open, one press to lock".

[0043] The bottom-opening glove box 7 located inside the glove box assembly 1023 adopts a joint control scheme of motor, latch and spring rope: when the occupant triggers the unlocking command through the central control screen, the motor drives the latch to exit the glove box shell lock, and the door body flips and droops around the lower hinge at a controlled speed under the combined action of its own weight and the tension of the rope. The opening angle is limited by the length of the rope to a position that is convenient for reaching out and taking things without touching the legs; when closing the lid, lift the door body slightly, and the latch automatically resets and locks under the action of the conical guide surface, cooperating with the closing limit blade and the anti-passing buckle to ensure that the door body and the lower edge of the first upper panel 1021 and the right end panel assembly of the instrument panel are tightly fitted without abnormal noise.

[0044] In any of the above embodiments, the upper storage box assembly 6 corresponds to the lower glove box 7 along the vehicle Z direction, and the openings of the upper storage box assembly 6 and the lower glove box 7 in the unfolded state are facing away from the front end of the vehicle along the vehicle X direction.

[0045] In this embodiment, in the central longitudinal section of the rear table structure 102, the upper storage box assembly 6 is directly opposite to, that is, perpendicular to, the lower glove box 7 located below it in the vehicle Z direction. The two form a three-dimensional storage channel that echoes each other up and down with the same vertical projection axis of the vehicle body. When the occupants trigger the lid opening mechanisms respectively, the lid of the upper storage box assembly 6 will swing upward with the hinge as the center of the circle, while the door body of the lower glove box 7 will flip downward around the lower hinge. In the unfolded state, the openings of both are open along the vehicle X direction, facing away from the front end and toward the chest and abdomen of the occupants. Since the opening directions are completely consistent and the movement paths are located on the upper and lower layers of the table, vertical interference between the lid and the door body is avoided, and the occupants only need to maintain an upright sitting posture to complete the vertical taking and placing operations from top to bottom within the normal adjustment range of the seat. Furthermore, the upper and lower corresponding and open in the same direction layout concentrates high-frequency interactions such as tablet placement or document reading on the upper platform, and the storage of large or insulated and refrigerated items is concentrated in the lower cavity, forming a human-computer interaction zone with clear functional divisions. At the same time, the height difference formed by the double-layer table provides natural shielding for the two storage openings, effectively preventing driving vibrations or items from slipping out and colliding with passengers during sudden braking, and the movement trajectories of the two flip covers avoid the steering column, legroom and airbag ejection area, taking into account operational convenience, storage safety and ride comfort, and ultimately achieving a multi-dimensional optimal balance of storage capacity, opening angle and ergonomics within the limited longitudinal depth of the dashboard.

[0046] In any of the above embodiments, the upper cover of the upper storage box assembly 6 is rotatably mounted on the top of the first upper panel 1021, and the inner bottom wall of the upper storage box assembly 6 and the top of the first upper panel 1021 extend horizontally along the vehicle X direction.

[0047] In this embodiment, in the rear table structure 102, the upper cover of the upper storage box assembly 6 is rotatably mounted on the top folded edge of the first upper panel 1021 through a hidden equiaxial hinge and a damper assembly, and the hinge axis is arranged laterally along the Y direction of the vehicle, so that the upper cover can be swung upward in the Z direction of the vehicle around the axis at a smooth and controllable angular velocity; this top hinge + damping arrangement not only avoids the traditional side hinge from encroaching on the arm space of the left and right passengers during the opening process, but also ensures that the upper cover can rely on the built-in friction damping to achieve hovering at any opening angle to prevent accidental rebound.

[0048] When the upper cover is fully closed, its outer surface forms the same continuous curved surface with the upper surface of the first upper panel 1021; and when the upper cover is opened to the maximum angle, the inner bottom wall of the upper storage box assembly 6 and the top of the first upper panel 1021 extend horizontally together along the vehicle X direction, and the two are spliced ​​on the horizontal plane to form a wide table top: the front edge is the finishing surface of the first upper panel 1021, and the rear edge is the finishing surface of the storage box bottom wall. There is no step transition between the two, and the sunken design of the hidden hinge ensures that the splicing gap is compressed to a minimum, thereby providing the co-pilot and the driver with a flat and stable support platform that runs from the center of the vehicle body to both sides. The platform can directly carry tablets, handwriting boards, portable keyboards and even small cutlery, and because it is located at the chest and abdomen height of the occupants, it can realize "line-of-sight translation" viewing and operation, significantly improving the experience in multiple scenarios such as parking office, audio-visual entertainment or children doing homework; at the same time, the bottom wall of the storage box becomes the top surface of the hidden cavity in the closed state, and the items stored inside are protected by the upper cover and the first upper panel 1021 to ensure that they will not leak out during driving vibrations.

[0049] In any of the above embodiments, the front platform structure 101 includes a second upper panel 1011 and a partition plate 1012 , and the partition plate 1012 connects the second upper panel 1011 and the first upper panel 1021 along the X direction of the vehicle.

[0050] The partition plate 1012 is located between the inner cavity of the front deck structure 101 and the inner cavity of the rear deck structure 102 along the vehicle X-direction.

[0051] In this embodiment, in the front platform structure 101, the second upper panel 1011 serves as the appearance top plate of the functional layer, which runs across the driver's seat and the co-driver's seat along the vehicle X direction. Its leading edge is rigidly connected to the front windshield base through sealing strips and reinforcing beams to ensure the transmission of normal impact of the collision, while the trailing edge forms a level difference in height with the first upper panel 1021 through a set of stepped staggers. In order to achieve structural division and functional isolation of the two-layer table tops while maintaining the continuity of the shape, the present invention adds a partition plate 1012 extending along the X direction of the vehicle between the second upper panel 1011 and the first upper panel 1021, which can also be regarded as a vertical splicing beam. The partition plate 1012 is plugged in from top to bottom, and the top is locked with the rear folding edge of the second upper panel 1011 by a dovetail groove, and the bottom is firmly fixed to the front folding edge of the first upper panel 1021 by a combination of arc-shaped slots, studs, and nylon lock nuts, thereby constructing a rigid support between the two table tops to form a vertical bridge.

[0052] In terms of spatial layout, the partition plate 1012 is located between the inner cavity of the front table structure 101 and the inner cavity of the rear table structure 102 along the vehicle X direction, so that the transverse cross-section forms a sandwich arrangement of the front cavity, the partition plate 1012, and the rear cavity; the partition plate 1012 physically isolates the airflow and noise of the cavities on both sides. On the one hand, it blocks the heat and noise interference between the blowing air duct and the vehicle cooling air duct, ensuring that the air conditioning airflow is accurately directed to the occupants after passing through the bridge-type guide holes set by the partition plate 1012; on the other hand, the internal rib reinforcement and honeycomb structure significantly improve the anti-sinking stiffness of the two-layer table in the out-of-plane direction, so that the instrument cluster, speakers and upper finishes maintain a stable position under driving vibration conditions, avoiding assembly interference with the rear interaction area.

[0053] Partition panel 1012 also features prefabricated multifunctional wiring ducts and diagonal air guides, arranged along the vehicle's X-axis. The ducts provide layered routing for the wiring harnesses for the instrument cluster, multi-function steering wheel switches, and auxiliary instrument display. During modular assembly, the harnesses can be clipped into the partition panel 1012 slots before being connected to the rear compartment wiring bridge, preventing them from dangling directly across the two compartments. The diagonal air guides align with the front air conditioning duct outlets. Airflow through partition panel 1012 is directed close to the lower edge of the windshield, forming a high-velocity jet while preventing condensation or dust accumulation in the lower storage area. Because the structural gaps between partition panel 1012 and the two upper panels are completely covered with a double-layer EPDM sponge padding and acoustically absorbent needle cloth, the overall wraparound belt not only visually forms a continuous curve with a high front and a low rear, but also acoustically creates a sound barrier between the functional and interactive compartments, minimizing fan noise disturbances for occupants.

[0054] In any of the above embodiments, the functional components of the vehicle further include an air-conditioning blowing duct 8 , and the air outlet of the air-conditioning blowing duct 8 is provided on the partition plate 1012 .

[0055] In this embodiment, within the functional layer of the front table structure 101, the vehicle functional components further include an air-conditioning blowing duct 8, which is arranged forward in the horizontal plane relative to the rear edge of the second upper panel 1011, and its flow channel passes through the upper part of the inner cavity of the front table structure 101, passes from left to right along the vehicle X direction, and forms branch connections with the driver's face blowing duct, the co-driver's face blowing duct and the front windshield defrost duct at several positions; in order to allow the air-conditioning airflow to act on the occupants as soon as possible after leaving the functional cavity, the air outlet of the air-conditioning blowing duct 8 is directly set on the partition plate 1012: a long arc-shaped slit following the curvature of the table is opened in the middle section of the partition plate 1012, and a guide grid with multiple guide blades is embedded at the bottom of the long slit. The guide grid can be synchronously adjusted in one direction or two directions by a stepping motor or a damping lever.

[0056] When the air-conditioning system enters the blowing or mixed mode, the main airflow passes through the air-conditioning blowing duct 8, is bundled inside the partition plate 1012, and then is ejected from the air outlet. The airflow first flows along the outer surface of the partition plate 1012 and merges with the stepped drop of the second upper panel 1011-the first upper panel 1021, and then diffuses in a horizontal fan shape at the height of the chest and abdomen of the occupant, so as to achieve a wrap-around coverage of the upper body of the occupant by high-level cold air (or warm air); at the same time, since the partition plate 1012 is located between the inner cavity of the front table structure 101 and the inner cavity of the rear table structure 102, the air outlet is naturally away from the rear storage area on the jet path, avoiding direct blowing onto the upward-opening storage box or the downward-opening glove box 7, which may cause temperature difference condensation or paper items to flutter. The front end of the air-conditioning blower duct 8 is connected to the high-pressure side hose of the air-conditioning assembly with a corrugated compensation joint, which can absorb tiny vibrations of the front surface and reduce wind noise; a detachable inspection port is provided on the back of the partition plate 1012 at its rear end, which is convenient for filter cleaning and air duct disinfection without removing the upper panel.

[0057] The guide vanes can individually adjust the blowing angle under the command of the central control panel or the in-vehicle voice system. Combined with the "thin at the top and thick at the bottom" cross-sectional design of the partition panel's 1012 arc-shaped long slits, the longitudinal distribution of the airflow presents a gradient of dense at the top and sparse at the bottom, fitting the double-layer table top contour of the cabin with high front and low back.

[0058] In any of the above embodiments, an outlet for the passenger explosion-proof airbag 9 to be exposed is formed on the second upper panel 1011 .

[0059] When the passenger explosion-proof airbag 9 is located in the vehicle cab, a guide cavity connected to the air outlet of the air-conditioning blowing duct 8 is formed between the partition plate 1012 , the first upper panel 1021 and the passenger explosion-proof airbag 9 .

[0060] In this embodiment, an arc-edge trapezoidal explosion-proof airbag exposure opening is pre-formed in the high-rise area on the right side of the second upper panel 1011 by an integrated mold opening method. The outer contour of the outlet remains consistent with the overall curved surface of the upper panel, and is covered with a thin-walled, easily breakable decorative panel under normal driving conditions; when the vehicle collides and triggers the passenger side explosion-proof airbag 9, the explosion-proof airbag module penetrates the decorative panel upward in the Z direction of the vehicle and quickly inflates and unfolds, and the plane of its folded body is located exactly in the narrow space between the back of the second upper panel 1011 and the front edge of the partition plate 1012.

[0061] In order to ensure that the gas shock wave and inflation heat during the deployment process can be dissipated immediately, a guide cavity is constructed between the partition plate 1012, the first upper panel 1021 and the back shell of the passenger explosion-proof airbag 9 module by utilizing the structural gap: the guide cavity has the rear surface of the partition plate 1012 as the front wall, the front folded edge of the first upper panel 1021 as the top wall, the explosion-proof airbag back shell and the mounting bracket as the back wall, and the bottom is enclosed together with the back of the second upper panel 1011. The cross section is gradually expanding backwards. The trumpet-shaped structure connects its front end to the air outlet of the air conditioning blower duct 8 through a long curved slit in the middle of the partition panel 1012. This allows the air conditioning air to flow along the diversion cavity in front of the passenger's knees during normal operation, removing trapped heat and moisture from the hidden compartment, keeping the airbag folded body dry, and delaying material aging. In extreme collision scenarios, the residual pressure released during airbag inflation can also be quickly evacuated to the front functional cavity through the same path, preventing the airbag from rebounding and injuring passengers due to excessive back pressure. Thus, by providing a precisely matched airbag exposure port on the second upper panel 1011 and constructing a diversion cavity based on the natural gaps between the partition panel 1012, the first upper panel 1021, and the airbag module, the airbag not only meets the requirements for safe airbag deployment and heat and pressure dissipation, but also forms an airflow circulation loop with the air conditioning blower duct 8, achieving multi-objective coordinated optimization of occupant protection, safety mechanism layout, and air conditioning system thermal management, further enhancing the overall safety and long-term reliability of the cabin.

[0062] The embodiment of the second aspect of the present invention provides a fixing method. In some embodiments of the present invention, such as Figure 4 As shown, the fixing method includes the following steps: S101 , assembling the instrument panel trim 1 on the vehicle cab, and dividing the inner cavity of the front platform structure 101 and the inner cavity of the rear platform structure 102 along the vehicle X direction.

[0063] S102 , dividing vehicle functional components and vehicle interactive components according to the functions of the vehicle components pre-installed inside the instrument panel trim 1 .

[0064] S103 , along the vehicle Z direction or the vehicle Y direction, vehicle functional components are installed in the inner cavity of the front platform structure 101 , and vehicle interactive components are installed in the inner cavity of the rear platform structure 102 .

[0065] S104, in the Y direction of the vehicle, the portion of the vehicle functional components located in the vehicle cab is formed into a first enveloping structure, and the portion of the vehicle interactive components located in the vehicle cab is formed into a second enveloping structure.

[0066] S105: Dispose the second encircling structure closer to the driver and the passenger seat relative to the first encircling structure along the vehicle Z direction and the vehicle X direction.

[0067] The present invention provides a fixing method that first utilizes X-axis hard partitioning of the front and rear panel cavities in S101, combined with pre-classification of functional and interactive components in S102, so that wiring harnesses, air ducts, air bags, etc. are all returned to the front cavity at one time, and storage, displays, etc. are concentrated in the rear cavity; then S103-S105 are layered and installed in Z / Y order, avoiding the cross-insertion and repeated rework of multiple modules in traditional single-layer instrument panels, shortening the assembly cycle and unifying the positioning reference, greatly reducing cumulative tolerances and on-site debugging workload.

[0068] The front cavity only carries high-frequency vibration or high-temperature and high-pressure components such as air-conditioning ducts, speakers, and airbags, while the rear cavity carries interactive components such as storage boxes and display screens that require precise opening and closing and touch. The two are physically isolated to avoid crosstalk from heat, noise, and mechanical impact. At the same time, upper and lower wraparound double belts are constructed in the Y-direction, allowing cold and warm airflow, auditory sound field, and information vision to dominate the upper layer, while storage and equipment operations are relocated to the lower layer, making the occupants feel more comfortable and the operation path more natural.

[0069] S104-S105 places the functional surround belt at the front of the upper layer, making the airbag deployment area and the windshield defrost airflow path more direct, and improving collision response and defrost efficiency simultaneously; the interactive surround belt moves downward and backward, freeing up the field of view of the top of the instrument and providing a horizontal platform for the co-driver to place a tablet or laptop, enriching the usage scenarios without blocking driving information.

[0070] After the two inner cavities are independent, the air duct can be directly directed to the air outlet of the partition plate 1012, and the wiring harness is routed to the vehicle computer and auxiliary instrument 3 through the rear cavity bridge at one time without the need for cross-layer perforation; the air flow resistance and the friction points of the wiring harness are simultaneously reduced, the wind noise and vibration transmission links are cut off, and later maintenance only requires opening the corresponding table to quickly locate the components.

[0071] The front and rear countertops are locked together through the partition board 1012-spliced ​​vertical board-upper panel step, forming a closed loop under stress; the assembly sequence is to first fix the upper load-bearing parts and then mount the lower interactive parts, avoiding secondary cutting or reinforcement of the main load-bearing structure by the later-installed components. After long-term use, the sinking of the countertop, shaking of the flip cover and abnormal noise of the panel are significantly reduced.

[0072] In summary, this fixing method uses the assembly strategy of "differentiation first, layering second, and then embracing" to achieve process streamlining and quality consistency on the manufacturing side, minimize thermal, acoustic, and force coupling on the structural side, and provide a safer, more spacious, and versatile driving experience on the user side, reflecting the comprehensive advantages of the entire chain from production efficiency to passenger experience.
