Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a lightweight pickup truck cab frame. Background Technology

[0002] The demand for pickup trucks in the automotive market is increasing, and various modified vehicles based on pickup trucks are emerging one after another; the demand for modifying pickup trucks into multi-purpose vehicles with the 6 series M1 is also increasing; however, normal pickup trucks belong to the N1 category, and M1 category vehicles need to meet the passenger car-related regulations requirements of higher standards than N1 category vehicles.

[0003] GB 26512-2021 "Commercial Vehicle Cab Occupant Protection" stipulates that for N1 category vehicles, the cab only needs to meet the conventional frontal impact test, roof strength test, and rear bulkhead strength test. The roof strength test requires a static load equivalent to the maximum permissible axle load of the vehicle's front axle or multiple front axles (approximately 13,000 N for pickup trucks), which is relatively easy to achieve for N1 category pickup trucks. However, conventional designs cannot meet the requirements of GB 26134-2024 "Passenger Cars Roof Compressive Strength" (latest draft for public comment), which stipulates a load of 3.0 times the vehicle's curb weight (approximately 66,000 N) but not exceeding 60 kN.

[0004] To meet the requirements of GB 26134-2024 "Roof Compressive Strength of Passenger Cars" regulations for the facelifted M1 class models, the traditional design approach is as follows: to ensure the competitiveness of the basic pickup truck market, N1 class pickup truck models use traditional pickup truck designs; for the facelifted M1 class models, the side panels and roof need to be redeveloped; the sheet metal of the left and right A and B pillars needs to use thicker high-strength steel or even hot-formed parts; for the entire vehicle platform, this requires double the investment in stamping molds, welding facilities, and welding tooling for the side panel and roof assembly, which also increases the complexity of manufacturing; in particular, the overall vehicle weight will also increase significantly, which is not the best solution for manufacturers. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lightweight pickup truck cab frame, which solves the problem that traditional left and right A and B pillar sheet metal requires the use of thicker high-strength steel or even hot-formed parts. This would require double the investment in stamping molds, welding facilities, and welding tooling for the side panels and roof assembly of the entire vehicle platform, and would also increase the complexity of manufacturing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight pickup truck cab frame, comprising: The side frame is equipped with a CBS structural skeleton. The CBS structural skeleton is assembled into the internal cavity of the side frame and is coated and baked. The structural adhesive on the surface of the CBS foams, thereby connecting the side frame and the CBS structural skeleton and increasing the strength of the cab side frame structure. The top cover frame is installed between the side frame frames on both sides, and the top cover frame together with the side frame frames on both sides forms an integral cab frame.

[0007] Preferably, the side frame consists of a left side frame and a right side frame.

[0008] Preferably, the left side frame consists of a left outer panel, a left A-pillar, and a left B-pillar, with the two ends of the left A-pillar connected to the top of the left outer panel and the top of the left B-pillar, respectively.

[0009] Preferably, the CBS structural skeleton in the left side frame includes: The CBS structure under the left A-pillar is snapped into the lower part of the internal cavity of the left A-pillar; The CBS structure on the left A-pillar is snapped onto the top of the internal cavity of the left A-pillar; The left B-pillar has a CBS structure, which is snapped into the internal cavity of the left B-pillar.

[0010] Preferably, the right-side enclosure frame consists of a right outer panel, a right A-pillar, and a right B-pillar, with the two ends of the right A-pillar connected to the top of the right outer panel and the top of the right B-pillar, respectively.

[0011] Preferably, the CBS structural skeleton in the right-side enclosure includes: The CBS structure under the right A-pillar is snapped into the lower part of the internal cavity of the right A-pillar; The CBS structure on the right A-pillar is snapped onto the upper part of the internal cavity of the right A-pillar; The right B-pillar has a CBS structure, which is snapped into the internal cavity of the right B-pillar.

[0012] Preferably, the top cover frame includes: The front crossbeam of the roof is located between the left and right side frames; The right connecting plate is fixedly installed at one end of the front crossbeam of the top cover, and the right connecting plate is fixedly connected to the right side frame. The left connecting plate is fixedly installed at the other end of the front crossbeam of the top cover, and the left connecting plate is fixedly connected to the left side frame.

[0013] Preferably, an outer plate of the top cover is fixedly installed between the front crossbeam, the right connecting plate, and the left connecting plate of the top cover.

[0014] This utility model discloses a lightweight pickup truck cab frame, which has the following beneficial effects: 1. This lightweight pickup truck cab frame, by adding a CBS structural skeleton to the side frame, integrates these CBS components into the cab of the already developed N1 category vehicle, thereby deriving a cab that meets the collision requirements of M1 category vehicles. Ultimately, this achieves the goal of designing a lightweight cab compatible with both N1 and M1 category vehicles without investing in and manufacturing space for a single cab model, and without increasing the weight, cost, or investment of the base vehicle.

[0015] 2. The lightweight pickup truck cab frame incorporates a CBS structural skeleton for the A and B pillars within the A-pillar and B-pillar cavities. The CBS is essentially composed of a thermoplastic composite material carrier and an expandable adhesive. After painting and baking, the adhesive connects the A-pillar, B-pillar, and the CBS structural skeleton itself, integrating the composite material skeleton with the vehicle body. This enhances the rigidity and strength of the cab's A and B pillars, thereby improving the cab's resistance to deformation under top loads. Attached Figure Description
