Description

Technical Field

[0001] This utility model relates to the field of automotive supplies technology, specifically a pickup truck external extension rack. Background Technology

[0002] In existing pickup truck usage scenarios, users often face the problem of insufficient cargo loading space.

[0003] While traditional pickup truck cargo beds offer a certain loading capacity and can meet the needs of transporting small items daily, their limitations become particularly apparent when dealing with larger items or scenarios requiring additional loading space. For example, the original cargo bed space of a pickup truck is often insufficient when moving furniture, building materials, or carrying a large amount of equipment for outdoor adventures.

[0004] To address this issue, various pickup truck cargo box expansion solutions have emerged on the market.

[0005] However, most solutions have obvious flaws. Some simple extension racks are secured only by ropes or simple supports, which are easily loosened or even fall off during travel due to road bumps. This not only fails to effectively protect the cargo but may also pose a threat to road safety.

[0006] In addition, some of the expansion solutions are too bulky and complicated to install, which seriously affects the overall aesthetics of the vehicle and reduces the user experience.

[0007] Therefore, the development of a pickup truck external extension rack that is structurally stable, easy to install, and does not affect the vehicle's aesthetics has become an urgent market demand. Utility Model Content

Finally, he used the auxiliary fixing straps 91 and auxiliary fixing buckles 92 to further secure the cargo, ensuring safety during transportation. The entire installation process was simple and quick, and Mr. Zhang was very satisfied with the performance of the extension frame. Specific Implementation Example 2:

[0031] Ms. Li is an avid outdoor adventurer who frequently needs to carry a large amount of equipment on long trips. To meet her loading needs, she chose this new pickup truck external extension frame. During installation, she paid special attention to the tight connection between the extension frame and the cargo box, adjusting the positions of the reinforcing posts 2 and the fixing posts 6 to ensure the stability and load-bearing capacity of the extension frame. When loading equipment, she made full use of the extra space provided by the extension frame, neatly placing large items such as tents, sleeping bags, and cooking utensils on it, and reinforcing them with the auxiliary fixing components 9. During the journey, even on bumpy roads, the extension frame demonstrated good stability, ensuring the safety of the equipment. Ms. Li highly praised the practicality and stability of the extension frame.

[0032] In summary, this embodiment proposes an external extension frame for pickup trucks, comprising three crossbars 1 arranged in parallel. Each of the three crossbars 1 has a reinforcing post 2 on its two end sidewalls. Multiple curved crossbars 4 are evenly distributed at both ends of the two reinforcing posts 2. Extension rods 5 are fixedly connected to the ends of the multiple curved crossbars 4 away from the reinforcing posts 2. Fixing posts 6 are commonly provided at the ends of the multiple extension rods 5 away from the curved crossbars 4. The ends of the multiple extension rods 5 near the fixing posts 6 are hollow. Insertion extension posts 61 are fixedly connected to the ends of the two fixing posts 6 near the extension rods 5. The multiple insertion extension posts 61 are inserted into the corresponding extension rods 5. Multiple fixing bolts 7 are evenly threaded through the sidewalls of the two fixing posts 6. Auxiliary fixing components 9 are provided on the sidewalls of the multiple extension rods 5.

[0033] Both auxiliary fixing components 9 include an auxiliary fixing strap 91, and both auxiliary fixing straps 91 are tied to the extension rod 5 in a matching position. Each of the two auxiliary fixing straps 91 has an auxiliary fixing buckle 92 fixedly connected to its end furthest from the extension rod 5. Each of the two fixing posts 6 has an auxiliary fixing lug 8 fixedly connected to its furthest from each other.

[0034] Multiple intercepting crossbars 1 are evenly fixed at both ends to the side walls of the reinforcing columns 2. Anti-slip pads 21 are fixedly connected to the bottom of each of the two reinforcing columns 2. Insertion posts 3 are fixedly connected to the side walls of the two reinforcing columns 2 at the ends away from the intercepting crossbars 1. The positions of the multiple insertion posts 3 are at the same horizontal height as the positions of the intercepting crossbars 1.

[0035] There are six intercepting bends 4 in total. Each of the six intercepting bends 4 is fixedly connected to a matching plug post 3 at one end near the reinforcing post 2.

[0036] The working principle of this utility model is as follows: The working principle of this pickup truck external extension frame is mainly based on its reasonable structural design and stable connection method. During use, the user first ensures that the anti-slip pad 21 at the bottom of the reinforcing column 2 is tightly fitted to the bottom of the pickup truck cargo box to provide initial stability. Then, the intercepting crossbar 1 and intercepting bend 4 are connected to the reinforcing column 2 via the plug-in column 3 to form a stable frame structure.

[0037] This frame structure not only expands the loading area for goods but also effectively distributes the weight of the goods, reducing pressure on the bottom of the cargo box. Next, the user securely connects the extension rod 5 to the intercepting bend rod 4 and inserts the plug-in extension post 61 of the fixing post 6 into the hollow part of the extension rod 5. The tightening of the fixing bolts 7 ensures a stable connection between the extension rod 5 and the fixing post 6. This connection method not only enhances the overall structural strength of the extension frame but also improves its resistance to bumps and vibrations.

[0038] When loading cargo, users can use auxiliary securing straps 91 and auxiliary securing buckles 92 to additionally secure the cargo. These auxiliary securing components 9 further ensure the stability of the cargo during transportation, preventing it from loosening or falling off due to bumps. At the same time, the extension rack is designed with the pickup truck in mind, so its installation will not detract from the overall aesthetics of the vehicle; on the contrary, it may increase the vehicle's practicality and personalization.
