It is the main material that makes up the interior of the side panel of the vehicle body, and together with the outer side panel, it forms the side structure of the vehicle body. Its precise installation is crucial to the overall quality and safety of the vehicle.

[0003] Chinese patent document CN201921820049.6 discloses a cargo box side panel assembly, including an outer side panel, an inner side panel, and an integrally formed roll forming beam. The middle of the roll forming beam protrudes outward to form a first connecting portion, the lower part of the roll forming a second connecting portion, and the upper part of the roll forming a longitudinal support portion. The upper edge of the longitudinal support portion bends outward to form a transverse support portion, and the outer edge of the transverse support portion bends downward to form a shielding portion. The outer side panel is located below the transverse support portion and its upper part overlaps and is welded to the outer wall of the first connecting portion. The inner side panel is located below the transverse support portion and its upper part overlaps and is welded to the inner wall of the second connecting portion. This invention improves strength and rigidity while reducing production costs.

[0004] However, the above-mentioned patent has certain defects in use. In the existing technology, the safety, lightweighting and manufacturing cost control of the vehicle body structure have become the focus of industry research. The inner side panel and the outer side panel of the device are connected and fixed by lap welding. However, there is no positioning guide device between the inner side panel and the outer side panel, which results in insufficient welding accuracy and requires multiple positioning and clamping, which greatly reduces efficiency.

[0005] To address this issue, a high-strength extended side panel for light passenger vehicle bodies is proposed. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a high-strength extended side panel for a light passenger vehicle body includes an inner panel body 1. The inner panel body 1 is the basic structure of the entire side panel, undertaking the main support and protection functions of the side of the vehicle body. The inner panel body 1 is a thin plate, made of high-strength thin plate material, and formed into the required shape through precise stamping and welding processes, which ensures sufficient structural strength and achieves lightweight design. The inner panel body 1 is provided with positioning devices 4, and there are two positioning devices 4, which are symmetrically fixed on both sides of the top of the inner panel body 1.

[0026] The positioning device 4 includes a housing 41, with a cavity 46 inside the housing 41. Multiple springs 45 are provided inside the cavity 46. One end of each spring 45 is fixed inside the cavity 46, and the other end is provided with a guide block 44 and is fixedly connected to it to form an elastic support structure. A top cover 42 is also provided on the housing 41. The top cover 42 is fixedly connected to the housing 41, and the guide block 44 passes through the top cover 42. This design allows the positioning device 4 to have a certain buffering and self-adaptive capability when subjected to external forces.

[0027] The guide block 44 has symmetrical ear plates 43 on both sides, which are fixedly connected to it. When the inner panel body 1 is assembled with the side outer panel 2, the guide block 44 of the positioning device 4 contacts the corresponding guide groove, and the spring 45 provides appropriate elastic support to ensure accurate alignment.

[0028] The inner panel body 1 is provided with a vehicle window 7, an inspection port 5, and a wheel opening 6. The vehicle window 7 is located above the inner panel body 1, and the wheel opening 6 is located directly below the vehicle window 7. There are two inspection ports 5, which are symmetrically arranged on both sides of the wheel opening 6. The design of the vehicle window 7, the inspection port 5, and the wheel opening 6 meets the basic functional requirements of the vehicle.

[0029] A rectangular tube 3 is fixedly installed at the bottom of the inspection port 5 and a rectangular tube 3 is fixedly installed in the middle of the window 7. The rectangular tube 3 serves as a reinforcing structure to improve the strength and rigidity of the inner panel body 1 in these key areas.

[0030] The inner panel body 1 is provided with symmetrical guide strips 11, and a limiting plate 12 is provided at the bottom of the guide strips 11. The guide strips 11 are used for positioning and guiding the rectangular tube 3. The guide strips 11 not only serve to position and guide the rectangular tube 3, but also enhance the overall structural stability of the inner panel body 1. The limiting plate 12 is located at the bottom of the guide strips 11 to prevent the rectangular tube 3 from shifting or deforming during installation. Through the combined action of the guide strips 11 and the limiting plate 12, the overall structural stability of the inner panel body 1 is enhanced.

[0031] The working principle of this utility model is as follows: When in use, during the assembly of the body of a light passenger vehicle, the inner side panel assembly first needs to be positioned in the correct position, wherein the guide block 44 contacts the guide groove of the outer side panel 2, and the spring 45 provides appropriate elastic support to ensure that the inner panel body 1 can be accurately aligned, and the inner side panel and the outer side panel 2 are installed by insertion.

[0032] Once the positioning is complete, the ear plate 43 will be used to fix the side inner panel assembly to the vehicle body to ensure its stability during subsequent assembly and driving.

[0033] The rectangular tube 3 reinforcement structure will be installed in key areas of the inner panel body 1, such as the bottom of the access port 5 and the middle of the window 7. These reinforcement structures are fixed to the inner panel body 1 by welding to improve its strength and rigidity. The guide strip 11 and the limiting plate 12 will be used for positioning, guiding and fixing the rectangular tube 3 to ensure that the reinforcement structure can be installed correctly and function properly.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
