[0002] As is well known, a pickup truck is a vehicle with a cargo box designed behind the driver's cab. Therefore, pickup trucks have good passenger and cargo carrying functions. However, the structure of the cargo box is mostly fixed, and the loading space of the cargo is relatively fixed. Therefore, in order to improve the convenience of cargo carrying, an adjustable cargo box structure is proposed.

[0003] Existing truck cargo box structures generally include a floor, side panels, and a tailgate. The side panels are fixedly connected to the floor. A first hinge is fixed to the floor, and a second hinge is fixedly connected to the bottom of the tailgate. The first and second hinges are connected by a hinge shaft, and a locking device is installed between the tailgate and the side panels. Inner lining panels are fixedly connected to the floor, side panels, and tailgate. In use, the locking device is opened to open the tailgate, and the goods to be transported are loaded into the space formed by the cooperation of multiple inner lining panels. After the goods are loaded, the tailgate is rotated relative to the floor to rotate and rise back to its original position. Finally, the locking device is used to achieve the connection and positioning between the tailgate and the side panels.

[0032] Example

[0033] Please see Figure 1-9 An adjustable cargo box structure for automobiles includes a floor plate 1 and a rear tailgate 2, as well as a fixed partition 3 and two side partitions 4. The fixed partition 3 and the two side partitions 4 are all fixedly connected to the top of the floor plate 1, and the fixed partition 3 is fixedly connected between the two side partitions 4. The rear tailgate 2 is hinged to the floor plate 1. A fixed liner 5, a tail liner 6, and two side liner 7 are fixedly connected to the top of the floor plate 1. The fixed liner 5 is connected to the fixed partition 3 and is fixedly connected between the two side liner 7. The tail liner 6 is fixedly connected to the rear tailgate 2, and each of the two side liner 7 forms a side storage space with the two side partitions 4 respectively. Each of the two side storage spaces contains... The upper and lower sliding connection is equipped with a lifting barrier 8. The design of the lifting barrier 8 facilitates the rotation and installation of the extended side panel 13, making the folding and unfolding of the extended side panel 13 easier. The folded extended side panel 13 can be stored in the side storage space. The adjustment operation is simple, the folding structure is reasonable, and it occupies less space inside the cargo box after folding, making it more practical. There are two wheel arch areas on the bottom plate 1, and each of the two side panels 7 is equipped with a sheet metal area 30 that matches the wheel arch area. The lowest point of the inner side of the side storage space is higher than the highest point of the wheel arch area to ensure that there is enough space for tire installation. The protective side panel 12 is provided with a gap that matches the wheel arch area.

[0034] It should be further explained that the tops of the two lifting barriers 8 are fixedly connected to side frames 9, and the ends of the two side panels 7 that are close to each other are fixedly connected to straight rails 10 and curved rails 11. The straight rails 10 and curved rails 11 on the same vertical plane on the left and right sides are interactively fitted with protective side panels 12. Extended side panels 13 are rotatably connected to the protective side panels 12. Side frames 9 are provided with side grooves that match the extended side panels 13. The opening of the side grooves facilitates the limitation of the position of the extended side panels 13 after they are unfolded. The extended side panels 13 have good structural stability after unfolding. A tail storage space is formed between the tail panel 6 and the rear tail door 2. A tail fence frame 14 is slidably connected vertically within the tail storage space. Two tail rails 15 are fixedly connected to the end of the tail panel 6 that is close to the fixed barrier 3. A protective barrier 16 is slidably connected between the two tail rails 15. The design of the protective barrier 16 facilitates the separate rotation and installation of the extended tail panels 17, allowing the extended tail... The rotation, folding, and unfolding of the extended tail panel 17 are relatively easy. After folding, the extended tail panel 17 can be stored in the rear storage space. The adjustment operation is relatively simple, the folding structure is relatively reasonable, and it occupies less space inside the cargo box after folding, making it quite practical. The extended tail panel 17 is rotatably connected to the protective panel 16. Through the cooperation of the extended side panel 13 and the extended tail panel 17, the height of the cargo box can be adjusted by cooperating with the rear tail door 2 and the side panel 4. When the cargo is tall, it can be better used. During transportation, the cargo box of the car provides good protection for the cargo. The extended tail panel 17 is made of transparent material, which reduces the blind spot of the rearview mirror and ensures driving safety. The top of the rear grille frame 14 is fixedly connected to the rear frame 18. The rear frame 18 has a tail groove that matches the extended tail panel 17. The tail groove makes it easy to limit the position of the extended tail panel 17 after unfolding. The extended tail panel 17 has good structural stability after unfolding.

[0035] Furthermore, multiple composite side hook structures are installed between the side frame 9 and the side enclosure 4. Each composite side hook structure includes a side hook frame 19 and a side hook bracket 20. The multiple side hook frames 19 are fixedly connected to two side enclosures 4 respectively, and the multiple side hook brackets 20 are fixedly connected to two side frames 9 respectively. Each of the multiple side hook frames 19 is provided with a side through hole 21 that matches the side hook bracket 20. Through the design of the composite side hook structure, it is convenient to limit the relative position between the side frame 9 and the side enclosure 4 after the extended side panel 13 is folded, and it also has a hook function. The side hook bracket 20 is equipped with a side fixing device for mutual auxiliary positioning of the side hook frame 19 and the side hook bracket 20. The tail frame 18 and the rear tailgate 2 are equipped with multiple composite tail hook structures. Each composite tail hook structure includes a tail hook frame 22 and a tail hook bracket 23. The tail hook frames 22 are fixedly connected to the rear tailgate 2, and the tail hook brackets 23 are fixedly connected to the tail frame 18. Each tail hook frame 22 is provided with a tail through hole 24 that matches the tail hook bracket 23. The design of the composite tail hook structure facilitates the limitation of the relative position between the tail frame 18 and the rear tailgate 2 after the extended tail plate 17 is folded. It also has a hook function, which is quite practical. The top of the tail frame 18 is provided with two top grooves, and each top groove is slidably connected with a strip 31. Both side frames 9 are provided with The device is equipped with two slots, each containing a vertical shaft 32. Two strips 31 each have vertical holes that mate with the two vertical shafts 32. A tension spring 33 is fixedly connected to one end of each strip 31 inserted into the top slot. The vertical shafts 32 have notches that match the strips 31, defining the relative position between the tail frame 18 and the side frames 9. The tail hook frame 23 is equipped with tail positioning components for mutual positioning of the tail hook frame 22 and the tail hook frame 23. Multiple side positioning components and multiple tail positioning components each include insert rods 25. Each insert rod 25 has a slot, and a connecting shaft 26 is fixedly connected to each slot. Multiple connecting shafts... Each of the 26 is connected to a baffle plate 27. The side hook frame 19, side hook bracket 20, tail hook frame 22 and tail hook bracket 23 are all provided with insertion holes 28 that match the insertion rod 25. The baffle plate 27 can pass through the insertion hole 28 to facilitate limiting the relative position between the side hook bracket 20 and the side hook frame 19 or between the tail hook frame 22 and the tail hook bracket 23. The baffle plate 27 is provided with an eccentric strip hole 29. The connecting shaft 26 is located in the eccentric strip hole 29, and the baffle plate 27 can rotate 180 degrees with the connecting shaft 26 as support. By adjusting the baffle plate 27 relative to the connecting shaft 26, the passage or limitation of the baffle plate 27 relative to the insertion hole 28 can be achieved.

[0036] In summary, the working process of this adjustable cargo box structure is as follows: During use, the extended side panels 13 and extended rear panels 17 are first selected to be either folded or unfolded based on the type of cargo being transported. When the cargo is small or low, both extended side panels 13 and extended rear panels 17 are folded, as shown in the attached diagram. Figure 1As shown, when there are many or high-value goods to be transported, the extended side panels 13 and extended tail panels 17 are in the unfolded state, as shown in the attached diagram. Figure 4 As shown, during the unfolding process of the extended side plate 13, the baffle plate 27 is adjusted relative to the connecting shaft 26 so that the connecting shaft 26 enters the lowermost end of the eccentric strip hole 29 on the baffle plate 27 and then rotates 90 degrees to ensure the position of the baffle plate 27. At this time, the baffle plate 27 can pass through the insertion hole 28, and the insertion rod 25 is completely pulled out of the insertion hole 28. At this time, the positioning effect between the side hook frame 19 and the side hook bracket 20 is invalid, and the side frame 9 is pulled up relative to the side enclosure 4. Then, the protective side plate 12 and the extended side plate 13 are lifted together. Since the protective side plate 12 has a certain degree of elasticity, it can... After applying force, a certain arc can be generated. At this time, the extended side plate 13 can rotate relative to the protective side plate 12. After the extended side plate 13 rotates 180 degrees relative to the protective side plate 12, the protective side plate 12 is inserted back into its original position. Finally, the side frame 9 is lowered until the extended side plate 13 is inserted into the side groove. The extended tail plate 17 is unfolded in the same way according to the above steps. In this way, the height of the side enclosure 4 and the rear tail door 2 can be increased, so as to ensure that when the cargo is high, it can be better used. During transportation, the truck cargo box has a good shielding and protection effect on the cargo.
