Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a rear cargo box cover assembly for truck bodies. Background Technology

[0002] Truck covers are widely used to cover and protect the cargo area of ​​pickup trucks and other multi-purpose vehicles. They serve a variety of purposes, including protecting cargo from weather conditions such as rain, snow, and sun, improving vehicle aerodynamics, and providing additional theft protection. These covers are available in various configurations, such as hard-folding, soft-folding, roll-up, telescopic, and hinged.

[0003] Traditional truck tailgates are typically secured to both sides of the truck bed rails, with the front edge fixed near the cab and the rear edge near the tailgate. This rear securing is crucial, as it not only ensures the tailgate remains taut while the vehicle is in motion but also prevents wind from lifting it, thus reducing the vehicle's weather resistance and cargo safety.

[0004] However, a common problem in the industry is that the rear of the truck cover can become loose over time or under certain conditions. This can be due to fastener wear, thermal expansion and contraction of materials, repeated opening and closing, or the effects of wind and vibration during driving. When the rear becomes loose, the cover may wobble or lift, leading to increased air resistance, potential water ingress, and in severe cases, even partial or complete detachment.

The first connecting part 105a, the first pivot part 105b and the second pivot part 105c can rotate relative to each other. More specifically, the first pivot part 105b is fixedly connected to the first vertical frame 101b via a corner bracket, and the second pivot part 105c is fixedly connected to the second vertical frame 102a via a corner bracket, so that the second vertical frame 102a rotates relative to the first vertical frame 101b, thereby allowing the side rail 102 to rotate relative to the front rail 101.

[0093] like Figure 3 and Figure 7As shown, in some embodiments, the back column 103 includes two opposing and parallel third vertical frames 103b, and at least one second horizontal frame 103a is provided along a direction perpendicular to the two third vertical frames 103b. The two ends of the second horizontal frame 103a are respectively connected to the ends of the two second vertical frames 103b through two second corner connectors 103d. In addition, a third horizontal frame 140 is erected between the two third vertical frames 103b, and the third horizontal frame 140 is connected to the third vertical frames 103b through a second vertical connector 103c (i.e., a corner bracket).

[0094] like Figure 3 and Figure 6 As shown, in some embodiments, the third vertical frame 103b is connected to the second vertical frame 102a via a second hinge 106, forming a rotatable connection. Exemplarily, the second hinge 106 includes a second connecting portion 106a, a third pivot portion 106b, and a fourth pivot portion 106c. The second connecting portion 106a has a recess on one side and a protrusion on the other side.

The second pivot 106a, the third pivot 106b, and the fourth pivot 106c are rotatably connected to the protrusion via a pivot. More specifically, the third pivot 106b is fixedly connected to the second vertical frame 102a via a corner bracket, and the fourth pivot 106c is fixedly connected to the third vertical frame 103b via a corner bracket, so that the third vertical frame 103b rotates relative to the second vertical frame 102a, thereby allowing the back frame 103 to rotate relative to the side frame 102.

[0095] Figure 8 This is a fourth-view schematic diagram of the rear cargo cover assembly 100 according to some embodiments of the present invention. Figure 9 for Figure 8 A magnified view of region E in the middle. See below for reference. Figure 8 and Figure 9 The structure of latch assembly 150 is described below. As mentioned above, in some embodiments, multiple latch assemblies 150a, 150b have the same structure. Therefore, the following description will take the second latch assembly 150b as an example.

[0096] like Figure 8As shown, in some embodiments, the rear rail 103 may include a third crossbeam 140, which may include a receiving groove 1401 formed in the bottom surface of the third crossbeam 140 and extending laterally throughout the third crossbeam 140. A second latch assembly 150b is received in the receiving groove 1401. In some embodiments, the second latch assembly 150b includes a tongue 1502 that houses a spring member (not shown) within its internal space. A pin 1503 passes through one end of the tongue 1502 away from the side rail 120, and the spring member is fitted onto the pin 1503. In its natural state, the tongue 1502, under the bias of the spring member, engages its tongue portion 1504 with a latch member 600 coupled to the side rail 120. Thus, the second latch assembly 150b can latch the third crossbeam 140 onto the side rail 120 to prevent the accidental opening of the multiple frames. A cable 1505 is connected to the pin 1503. The loop 1506 is connected to the cable 1505, through which the user can apply a substantially vertical force to the bottom surface of the third crossbeam 140. When the user wants to open the rear hatch assembly 100, he / she can pull the loop 1506 to apply force to the cable 1505, thereby causing the tongue 1504 to retract and disengage from the latch member 600. Further details of the structure of the latch member 600 and its connection to the side rail 120 can also be found below.
