Description

Technical Field

[0001] The utility model relates to the technical field of a pickup truck rear luggage bar, in particular to a movable aluminum alloy rear luggage bar of a pickup truck. Background Art

[0002] At present, the traditional pickup truck bed on the market is generally a square and upright structure, that is, the storage space in the pickup truck bed is a rectangular structure, and the rear luggage bar that matches it does not need to have too many adaptation structures, and the rear luggage bar can be directly fixed and installed on the pickup truck bed. With the continuous modification of pickup truck models on the market, an outward eight longitudinal bar bed structure is popular in the market today. This bed structure is being promoted and applied. The outward eight longitudinal bar structure is that the storage space in the pickup truck bed is like an outward eight, narrowing from top to bottom. The pickup truck bed with an outward eight longitudinal bar structure can better reflect the design taper of the body and the design power of the body than the square and upright bed structure. However, there is no rear luggage bar that can be installed on the outer eight-rod structure on the market, and the traditional rear luggage bar structure cannot be well adapted for installation on the rear luggage bar; in addition, when the traditional rear luggage bar structure is installed on the outer eight-rod structure, there are still the following problems: (1) The rear luggage bar is fixedly installed on the outer eight-rod structure of the pickup truck bed, and cannot be moved or arbitrarily adjusted in the front and rear installation positions. In this way, the installation position cannot be adjusted according to actual needs, and the flexibility is insufficient. (2) In addition to the basic luggage bar performance, the traditional rear luggage bar cannot add some expansion parts for installation, and cannot expand other performances due to different needs. The scope of use is relatively single and the application range is narrow. (3) The traditional rear luggage bar is supported by iron or stainless steel, which is heavy and is not conducive to the lightweight design of the vehicle body. At the same time, the surface of this type of rear luggage bar often has a powder coating or paint coating. After frequent use, the coating will fall off or be scratched, resulting in an unsightly appearance and reduced anti-corrosion performance.

[0003] Therefore, it is necessary to make certain improvements to the rear luggage bar structure installed on the pickup truck bed in the prior art to improve the problems of the prior art, so as to develop an aluminum alloy rear luggage bar that can be easily moved forward and backward, is lightweight, and has improved expansion performance.

The movable aluminum alloy rear luggage bar is composed of an aluminum alloy leg, a leg bite structure, an arc-shaped width connector, an aluminum alloy crossbeam, an end face suspension, a top suspension, etc.; wherein the end face suspension and the top suspension are extended external connectors, which can be selected and installed according to the expansion needs; the aluminum alloy leg is connected and installed with the belt truck bucket longitudinal rod through the leg bite structure. The movable aluminum alloy rear luggage bar can be adapted to be installed on the pickup truck bucket longitudinal rod, especially when the end face of the pickup truck bucket longitudinal rod is an inclined surface, it can also be adapted to be installed.

[0029] In this embodiment 1, Figure 7 As shown, the leg engaging structure includes an engaging upper seat 8 installed at the bottom of the aluminum alloy leg, an engaging lower seat 9 which is embedded and assembled with the engaging upper seat and movably engages with the longitudinal rod of the pickup truck bucket, and an engaging screw 10 which passes through the engaging lower seat to form a fixed installation on the engaging upper seat. The leg interlocking structure can interlock and tighten the pickup truck bucket longitudinal bar through the mutual embedding and splicing of the interlocking upper seat and the interlocking lower seat, and the interlocking upper seat and the interlocking lower seat are tightened with each other through the interlocking screws, so as to achieve the purpose of interlocking the pickup truck bucket longitudinal bar; when it is necessary to adjust the angle of the entire movable aluminum alloy rear luggage bar, loosen the interlocking screws, and the entire movable aluminum alloy rear luggage bar can be moved forward and backward along the pickup truck bucket longitudinal bar. After adjustment is in place, tighten the interlocking screws to achieve the effect of fixed installation; of course, since the top and bottom surfaces of the pickup truck bucket longitudinal bar have a certain inclination angle, when adjusting the position, the front and rear end positions of the entire movable aluminum alloy rear luggage bar may be misaligned to a certain extent, that is, the front and rear ends of the movable aluminum alloy rear luggage bar are not necessarily in the same horizontal direction when in the horizontal direction, and the front end or rear end can be set back, so that the appropriate angle can be adjusted according to some goods on the pickup truck bucket, so as to achieve a practical installation and avoid obstruction to the placement of goods as much as possible.
