Description

Technical Field

[0001] The utility model relates to an automobile accessory, in particular to a pickup truck compartment expansion rack. Background Art

[0002] Pickup trucks, as multi-purpose vehicles with both passenger and cargo functions, are widely used in daily life and commercial transportation. However, existing pickup truck cabins are typically designed as fixed spaces, which is very limited when transporting large cargo. To improve the loading capacity and flexibility of pickup truck cabins, various expansion rack structures have emerged on the market in recent years, allowing the cabin to be expanded and adjusted according to different cargo needs. However, existing pickup truck cabin expansion racks still have several shortcomings in actual use, which are specifically reflected in the following aspects:

[0003] 1. Poor structural stability: Existing technologies often use simple connections for pickup truck bed expansion racks, such as bolting various supporting components together. While this design allows for a certain degree of cabin expansion, the numerous and dispersed connecting components can easily become loose or misaligned during assembly. This can lead to structural instability when carrying heavy loads, and can even cause deformation or damage. Especially during driving, vibrations from the cabin and irregular road surfaces can easily loosen these connecting components, significantly impacting safety and service life.

[0004] 2. Complex assembly and inconvenient operation: Existing pickup truck bed expansion racks often require multiple steps to assemble and disassemble, making the process very complex. In particular, numerous fasteners, such as bolts and nuts, are required to connect the components, requiring tools for installation, adding to the inconvenience. Not only does assembly take a significant amount of time, but errors can also lead to improper installation of the expansion rack, impacting normal use.

[0005] 3. Inadequate protection: Existing expansion racks often use metal components. While metal provides a certain level of strength and support, it is susceptible to erosion from natural factors like wind and rain over long periods of use, particularly when exposed to outdoor conditions. This can lead to rust or corrosion, reducing the overall durability of the expansion rack. Furthermore, some designs fail to provide adequate protection for the bottom and side components. For example, when carrying cargo, this can easily cause direct structural wear and tear, reducing the expansion rack's overall protection.

[0006] 4. Irrational hook structures fail to meet diverse needs: Some existing expansion rack designs feature a single hook structure that cannot be adjusted to accommodate varying cargo sizes and shapes. For example, the hook's fixing method is often inflexible, making it difficult to accommodate cargo of varying sizes and shapes. This results in unstable securement during transport, posing a safety hazard. Furthermore, some designs lack structural strength, making them prone to breakage or damage during use, resulting in hook failure. Therefore, further improvements are necessary.

[0033] In one embodiment, the connecting plate 2 and the crossbeam 1 are fixed together by welding.

[0034] In one embodiment, a first pad 5 is provided at the bottom of the crossbeam 1 , and the first pad 5 is made of rubber.

[0035] In one embodiment, the hook seat 3 includes a rib plate 33 , a top plate 34 and a bottom plate 35 distributed in a “C” shape; the first mounting hole 41 is provided on the top plate 34 .

[0036] In one embodiment, the bottom plate 35 is further provided with an upwardly extending hook plate 36 , and a second pad 6 is provided inside the hook plate 36 , and the second pad 6 is made of rubber.

[0037] In one embodiment, a reinforcing plate 37 is further provided on the side wall of the rib plate 33 , and the top and bottom of the reinforcing plate 37 are connected to the top plate 34 and the bottom plate 35 respectively.

[0038] In one embodiment, buckle plates 38 are respectively provided at both ends of the reinforcing plate 37 . Correspondingly, buckle grooves 39 are provided on the top plate 34 and the bottom plate 35 . The buckle plates 38 extend into the buckle grooves 39 and are connected thereto.

[0039] In one embodiment, the buckle plate 38 and the buckle groove 39 are fixed together by welding.

[0040] In one embodiment: the connecting seat 4 includes an outer panel 43, a top panel 44 and an inner panel 45 distributed in an inverted "U" shape, and the third mounting hole is set on the inner panel 45; a side panel 46 is also provided between the outer panel 43 and the inner panel 45, and a docking plate 47 is provided at the front and rear ends of the side panel 46. Correspondingly, a buckle groove 48 is provided on the side walls of the front panel and the rear panel, and the docking plate 47 is snapped into the buckle groove 48 to be connected thereto.

[0041] Working principle: The core structure of the expansion frame consists of a crossbeam 1 and a connecting plate 2. The crossbeam 1 adopts a trough-shaped structure, and its design enables it to have a strong load-bearing capacity when the car body is expanded. The connecting plate 2 plays the role of closing and reinforcing the crossbeam by being installed on the notch of the crossbeam 1. In order to further enhance the fixing effect, the top and bottom of the connecting plate 2 extend upward to form lap plates 23 respectively. These lap plates are closely matched with the lap grooves 11 provided on the crossbeam 1. After the connecting plate is embedded in the crossbeam notch, the lap plate is snapped into the lap groove, so that the two are tightly connected and effectively fixed. This design ensures the stability of the expansion frame and prevents the car body from loosening or deformation during use.

[0042] The interlocking design of the lap plate and the lap groove significantly improves the connection strength between the beam and the connecting plate, thereby enhancing the stability and load-bearing capacity of the expansion frame.

[0043] The hook base 3 is used to secure cargo and other components, and its top fits within the connecting base 4. A first mounting hole 41 is provided on the top of the connecting base 4. A first mounting bolt passes through the first mounting hole 41 and the second mounting hole 31 on the top of the hook base 3, and is screwed into place with a first nut 32, thereby securely connecting the hook base and the connecting base. Simultaneously, the side wall of the connecting base engages with the fourth mounting hole 21 on the connecting plate 2 through a third mounting hole, and a second bolt and second nut 22 securely connect the connecting base and the connecting plate. This bolt-nut assembly ensures a secure connection between the components and prevents loosening during use.

[0044] Through multiple bolt connections and a suit design, the combination of the hook seat and the connecting seat not only ensures the convenience of installation operation, but also enhances the fixing strength of the components and improves the overall reliability of the structure.

[0045] It should be noted that to further strengthen the hook base structure of the expansion rack, the hook base 3 utilizes C-shaped ribs 33, which together form a stable support structure with a top plate 34 and a bottom plate 35. This design not only effectively disperses the forces applied to the hook base, but also ensures that the hook base will not deform or be damaged when carrying heavy objects. Furthermore, an upwardly extending hook plate 36 is provided on the bottom plate 35. A second rubber pad 6 is positioned within this hook plate to protect the hook base and the carriage, preventing structural damage from vibration or friction during transportation.

[0046] The design of the "C"-shaped rib and hook plate greatly improves the load-bearing capacity and structural strength of the hook seat. At the same time, the use of rubber pads improves the protection performance of the hook seat and extends its service life.

[0047] Reinforcement plates 37 are installed on the side walls of the hook base, connecting to the top and bottom plates 34 and 35, respectively, forming a complete support system. These reinforcement plates further enhance the overall strength of the hook base, preventing structural instability or damage caused by concentrated forces under load. Furthermore, gusset plates 38 are installed at each end of the reinforcement plates. These gusset plates extend into gusset slots 39 in the top and bottom plates 34 and 35 and are welded together to ensure that all components remain secure during long-term use.

[0048] The design of the reinforcement plate and the gusset plate enhances the tensile and bending resistance of the hook seat, avoids structural deformation, and improves the stability of the overall structure through welding fixation.

[0049] To enhance the shock absorption performance of the expansion rack, a first rubber pad 5 is installed at the bottom of the crossbeam 1. This pad effectively absorbs road vibrations during travel, reducing the impact between the expansion rack and the carriage, and providing a shock-absorbing and cushioning effect. Furthermore, the second rubber pad 6 within the hook plate 36 is also made of rubber. This material not only prevents direct friction between the hook and the carriage, but also enhances the stability of the cargo, preventing displacement due to vibration during transport.

[0050] The rubber pad not only improves the shock absorption effect of the expansion frame, but also effectively extends the service life of the expansion frame and the carriage, and reduces the wear of the components.

[0051] Furthermore, multiple components are secured together by welding. For example, connecting plate 2 is welded to crossbeam 1, and gusset plate 38 is welded to gusset slot 39. This method of securing key components ensures a more secure connection, ensuring long-term stability and preventing loosening. This welded connection design enhances the overall strength of the expansion rack and prevents the risk of components coming loose during use.

[0052] The welding method further strengthens the overall structural strength of the expansion rack, ensuring that it remains stable under high load and long-term use.

[0053] Through the above structure and working principle, the pickup truck bed expansion rack of the present invention has the following significant technical advantages:

[0054] 1. Stable structure and strong bearing capacity: The overlap design of the beam and the connecting plate, the rib plate structure of the hook seat, etc. ensure that the expansion frame is not easily deformed under heavy load conditions, thereby improving the overall bearing capacity.

[0055] 2. Easy assembly and efficient operation: bolts and nuts are used for quick assembly, and some key components are fixed by welding, which simplifies the installation process and reduces maintenance requirements during use.

[0056] 3. Excellent protective performance and long service life: The addition of rubber pads significantly enhances the protective performance, reduces the damage to the structure caused by vibration and friction, and extends the service life of the expansion rack.

[0057] 4. High overall strength and good long-term stability: The reinforcement plate and welding connection method further enhance the overall strength, ensuring that the expansion rack remains stable and firm during long-term use.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
