It combines daily commuting with outdoor living, its design falling between traditional RVs and campervans. Its selling points are lightweight, flexibility, and economy. The ride-on caravan on a pickup truck is a fashionable product that integrates "clothing, food, shelter, and transportation," realizing "living while traveling, and traveling while living." Currently, ride-on caravans are generally fixed to the pickup truck cargo bed via a mounting chassis. This chassis is usually integrated with the caravan, which limits its adjustability and extension, thus only accommodating one size of ride-on caravan, resulting in poor flexibility and potentially affecting the stable installation of the ride-on caravan on the pickup truck cargo bed. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a frame structure for a foldable pickup truck cargo box. It features an adjustable tray that allows for flexible extension and retraction, facilitating adaptation to different cargo box sizes.

[0023] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] refer to Figures 1 to 4 As shown in the figure, the frame structure of a foldable pickup truck backpack cabin provided by this utility model embodiment includes a chassis frame 1. Adjustable trays 2 are slidably installed at both ends of the chassis frame 1. Support plates 601 are fixedly connected to the bottom of the chassis frame 1. A lead screw 6 is connected between the support plates 601 through a bearing. Two adjusting blocks 603 are threaded onto the lead screw 6. The bottom of one end of the adjustable tray 2 is connected to the corresponding adjusting block 603 through a guide slider 3. Buffer blocks 4 are fixed to the bottom of the front and rear ends of the adjustable tray 2. The bottom of the buffer blocks 4 is slidably connected to the top of the chassis frame 1. A rubber roller 5 is rotatably installed at the bottom of the other end of the adjustable tray 2. The rubber roller 5 is on the same horizontal plane as the bottom of the chassis frame 1.

[0026] Specifically, the two ends of the lead screw 6 are respectively provided with positive and negative thread grooves, and the two adjusting blocks 603 are respectively located on the positive and negative thread grooves. The upper end of the adjusting block 603 extends into the interior of the guide slider 3. The middle part of the chassis frame 1 is provided with a guide slide 101, and the outer wall of the guide slider 3 slides along the guide slide 101.

[0027] The above scheme facilitates the movement of the two adjusting blocks 603 to separate and move closer to each other, and provides precise guidance for the direction of movement. This allows the adjusting blocks 603 to drive the adjusting tray 2 to extend and retract, making it easy to fold and extend. It is also convenient to adjust to different sizes of room boxes, making it flexible to use.

[0028] Specifically, the guide slider 3 is fixedly connected to the bottom of the adjusting plate 2, the guide slider 3 has a sliding cavity 301 inside, the upper end of the adjusting block 603 is fixedly connected to the slide plate 604, the slide plate 604 slides along the sliding cavity 301 and the slide plate 604 is fixedly connected to the top of the sliding cavity 301 by a spring 302.

[0029] Using the above scheme, the adjusting block 603 can drive the guide slider 3 to move linearly along the lead screw 6, thereby driving the adjusting tray 2 to move linearly and realize telescopic adjustment. On the other hand, the adjusting block 603, together with the sliding cavity 301, the sliding plate 604 and the spring 302, can provide anti-vibration support for the bottom of the adjusting tray 2, improve the shock absorption and buffering effect of the adjusting tray 2 on the room box, improve stability and enhance protection performance.

[0030] Specifically, the buffer support block 4 is provided in several parts and is evenly distributed along the bottom of the adjusting plate 2. The buffer support block 4 is made of rubber material. The bottom of the buffer support block 4 is provided with an installation groove 401. A shaft 402 is fixedly connected to the installation groove 401. A plastic roller 403 is slidably sleeved on the shaft 402. The plastic roller 403 rolls along the top of the chassis frame 1.

[0031] The above scheme facilitates further improvement in the stability of the elastic support of the adjusting tray 2, and the plastic roller 403 makes the adjustment tray 2 move in a time-saving and labor-saving manner with high stability, which is conducive to further enhancing the seismic support and protection performance of the adjusting tray 2.

[0032] Specifically, a support block 502 is fixedly connected to the bottom of the adjusting plate 2, and a support rod 501 is fixedly connected between the support blocks 502. The rubber roller 5 is slidably sleeved on the support rod 501.

[0033] The above-mentioned scheme facilitates the movement and adjustment of the pallet 2. The bottom of the rubber roller 5 and the chassis frame 1 are flush, which makes it easy to support the pickup truck cargo box at the same time. It can also provide more elastic support for the pallet 2, enhance the shock resistance, and facilitate the folding and telescopic adjustment of the pallet 2, making it flexible to use.

[0034] Specifically, a motor 602 is fixedly installed on the support plate 601, and the output end of the motor 602 is fixedly connected to one end of the lead screw 6.

[0035] The above scheme facilitates the rotation of the lead screw 6, which in turn drives the adjustment block 603, guide slider 3, and adjustment tray 2 to move, thereby enabling flexible extension and retraction adjustment of the adjustment tray 2. It also makes it easy to fold the adjustment tray 2 onto the chassis frame 1, reducing the space occupied on the plane and making it convenient to carry and store.

[0036] Specifically, the adjusting plate 2 has mounting screw holes 201, and the bottom inner wall of the chassis frame 1 is fixedly connected to a fixing plate 102.

[0037] The above solution allows for easy adaptation of different sized cabin boxes by telescopically adjusting the pallet 2, ensuring stable installation of the cabin box and the pickup truck cargo box, and providing flexible use. The mounting screw holes 201 facilitate fixing the cabin box to the adjusting pallet 2, and the fixing plate 102 facilitates fixing the chassis frame 1 to the pickup truck cargo box, making it convenient to use.

[0038] The working principle of this utility model:

[0039] In use, the chassis frame 1 is fixed to the pickup truck cargo box by the fixing plate 102. The motor 602 drives the lead screw 6 to rotate, which drives the two adjusting blocks 603 to move along the lead screw 6, and drives the guide slider 3 to slide, realizing the extension and retraction adjustment of the adjusting tray 2. After adjusting to a suitable distance, the house box is fixed to the adjusting tray 2 through the mounting screw hole 201. The guide slider 3, the sliding cavity 301, the sliding plate 604 and the spring 302 cooperate to provide shock-absorbing support for the adjusting tray 2. When the adjusting tray 2 moves, the buffer block 4 and the plastic roller 403 reduce the movement resistance. The rubber roller 5 assists the movement of the adjusting tray 2. Finally, the house box and the pickup truck cargo box are stably installed. This device has both convenient adjustment and protective performance, and improves the efficiency of use.
