Detailed Implementation

[0041] The technical solution of the present invention will be further described in detail below with reference to embodiments and accompanying drawings. The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0042] like Figures 1 to 5 , Figure 8 As shown, the seat and main and auxiliary instrument panel assembly of the four-seat and five-seat universal vehicle body provided in this application includes: a universal lower body assembly 1 and an upper body assembly 2.

[0043] The lower body assembly 1 has a universal seat hole group for selectively installing the four-seat version second-row seats 7 or the five-seat version second-row seats 13, and a universal instrument panel hole group for selectively installing the four-seat version sub-instrument panel 5 or the five-seat version sub-instrument panel 12.

[0044] The lower body assembly 1 can be welded from the floor assembly, front bulkhead assembly, left and right longitudinal beams, cross beams, and various reinforcing plates to form the skeleton of the body-in-white. The universal seat hole group and the universal instrument panel hole group are a series of holes of specific size and position stamped in the corresponding positions of the skeleton components, such as the floor at the second row of seats and the center channel, and some holes have pre-embedded welding nuts.

[0045] The upper body assembly 2 integrates a universal seat belt fastener for selectively installing second-row seat belts in either the four-seat or five-seat configurations.

[0046] The upper body assembly 2 may include a side panel assembly, which includes an A-pillar, B-pillar, C-pillar, roof assembly, and rear panel assembly. The universal seat belt fastener may include a right-side backrest fixing hole, a right seat belt motor fixing hole 2d, and a right seat belt motor anti-rotation slot 2f on the right side panel for installing a reused right-side seat belt for the second-row seats, and a left-side backrest fixing hole 2a, a left seat belt motor fixing hole 2c, and a left seat belt motor anti-rotation slot 2e on the left side panel for installing a reused left-side seat belt for the second-row seats.

[0047] Specifically, a four-seat configuration is formed by adapting and installing the four-seat version sub-instrument panel 5 and the four-seat version second-row seats 7 on the lower body assembly 1, and installing the four-seat version second-row seat belts on the upper body assembly 2; or a five-seat configuration is formed by adapting and installing the five-seat version sub-instrument panel 12 and the five-seat version second-row seats 13 on the lower body assembly 1, and installing the five-seat version second-row seat belts on the upper body assembly 2.

[0048] The four-seat sub-dashboard 5 and the four-seat second-row seats 7, or the five-seat sub-dashboard 12 and the five-seat second-row seats 13, are mechanically connected to the lower body assembly 1 and the upper body assembly 2 via their own mounting brackets, bolts, locating pins, etc. For example, the mounting feet on the seat frames of the four-seat second-row seats 7 and the five-seat second-row seats 13 are screwed into nuts pre-embedded in the vehicle floor by bolts; the plastic clips or studs at the bottom of the four-seat sub-dashboard 5 and the five-seat sub-dashboard 12 are inserted into or pass through body holes and then fastened from the back with nuts.

[0049] This application allows for the matching of the second-row seats 7 (four-seat version) or 13 (five-seat version) via the universal seat hole group on the lower body assembly 1, and the matching of the sub-instrument panel 5 (four-seat version) or 12 (five-seat version) via the universal sub-instrument panel hole group; and the matching of the second-row seat belts (four-seat version or five-seat version) via the universal seat belt fasteners on the upper body assembly 2. This achieves universality for both four-seat and five-seat vehicle bodies, and the body sheet metal parts can be used for both types of vehicles. This reduces mold development costs and vehicle manufacturing costs, increases the flexibility of the production line, facilitates the co-production of four-seat and five-seat vehicles, improves production efficiency, reduces assembly risks, shortens the development cycle, and reduces R&D costs.

This module is located near the universal seat hole group and is equipped with anti-misconnection connectors. The bottom of the seat cushion frame of the four-seat version second-row seat 7 and the five-seat version second-row seat 13 are equipped with corresponding integrated electrical connectors. When the seats are installed and fixed, the electrical connectors automatically align and plug into the universal interface module pre-embedded in the body, enabling plug-and-play use of the seat's electric functions without the need for complex wiring harness connections on the final assembly line. This universal design of the electrical interfaces simplifies the assembly process for high-end models (with functional seats), reduces the risk of electrical connection errors, and further improves the flexibility and efficiency of the production line.
