Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically a modular pickup truck bed extension frame. Background Technology
[0002] Pickup trucks, with their combined passenger and cargo carrying capabilities, are widely used in various scenarios. To further enhance the loading capacity and functionality of pickup trucks, an extended roll bar device is usually installed in the truck bed (also known as the cargo box). Existing pickup truck extended roll bars are mainly woven or welded from high-strength steel pipes (such as carbon steel or stainless steel), featuring lightweight, durability, and rust resistance. Their typical structure mainly includes two sets of symmetrically arranged supports, which are fixed to the side walls or edges of the truck bed. The supports are connected and reinforced by one or more transversely arranged beams, forming a relatively stable frame structure.
[0003] Existing extended gantry structures have the following shortcomings: 1. Existing gantry structures are mainly limited to providing vertical railings or support points for securing ropes to tie goods or simply placing a few items on top. They cannot accommodate roof racks, tents, or other items, lacking flexible and multi-functional expansion capabilities; 2. Existing gantry structures are usually integrally welded or fixedly connected, making convenient assembly and disassembly impossible according to actual usage needs. Therefore, this application provides a modular pickup truck bed extension frame to solve the above problems. Utility Model Content

The support frame and mounting frame are modularly designed. The support frame can be used as the base of the extension platform, and the mounting frame can be used as a roof platform. It can also be used to install luggage racks, roof tents, water tanks, bicycles and other equipment. It has multiple functions and the mounting frame can be disassembled and assembled as needed, which is highly flexible and can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular pickup truck bed extension frame, including a support frame, an mounting frame installed on the top of the support frame, the support frame including two sets of symmetrically arranged brackets, with a crossbeam connecting the two brackets in the same set, and a longitudinal beam connecting the two brackets on the same side, the mounting frame having two parallel and symmetrically arranged fixed beams, the tops of the two brackets on the same side being connected by the fixed beams, and several movable beams installed between the two fixed beams.
[0006] As a preferred embodiment of this utility model, the bracket is installed on the truck bed by bolts.
[0007] As a preferred embodiment of this utility model, the upper end of the bracket on the side corresponding to the crossbeam is provided with a slot, and the crossbeam is movably inserted into the slot.
[0008] As a preferred embodiment of this utility model, the side of the bracket corresponding to the longitudinal beam is bolted with a connecting seat, and the end of the longitudinal beam is sleeved on the connecting seat.
[0009] As a preferred embodiment of this utility model, the fixed beam and the movable beam are provided with sliding grooves on their corresponding sides, and the end of the movable beam is slidably disposed in the sliding grooves.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-6 This utility model provides a technical solution: a modular pickup truck bed extension frame, including a support frame, with an mounting frame installed on the top of the support frame. The support frame includes two sets of symmetrically arranged brackets 1, with a crossbeam 4 connecting the two brackets 1 in the same set, and a longitudinal beam 5 connecting the two brackets 1 on the same side. The mounting frame has two parallel and symmetrically arranged fixed beams 6, with the tops of the two brackets 1 on the same side connected by the fixed beams 6. Several movable beams 7 are installed between the two fixed beams 6. The brackets 1, crossbeams 4, and longitudinal beams 5 form the support frame, which is installed on the truck bed to support the mounting frame. The fixed beams 6 and movable beams 7 form the mounting frame, which can be used as a roof platform for convenient installation of roof tents, water tanks, bicycles, and other equipment.
[0021] Without installing a mounting bracket, the support frame can be used directly to install the roof rack.
[0022] Furthermore, bracket 1 is installed on the truck bed with bolts for easy installation.
[0023] Furthermore, a slot 2 is provided on the upper end of the side of the bracket 1 corresponding to the crossbeam 4, and the crossbeam 4 is movably inserted into the slot 2. Then, holes are drilled on the bracket 1 and the crossbeam 4, and the bracket 1 and the crossbeam 4 are fixedly connected by bolts and nuts.
[0024] Furthermore, the side of the bracket 1 corresponding to the longitudinal beam 5 is bolted with a connecting seat 3, and the end of the longitudinal beam 5 is sleeved on the connecting seat 3. Holes are drilled in the longitudinal beam 5, and the longitudinal beam 5 is connected to the connecting seat 3 with bolts.
[0025] Furthermore, the fixed beam 6 and the movable beam 7 have corresponding grooves on their sides, and the end of the movable beam 7 is slidably disposed in the groove. Holes are made at the ends of the movable beam 7 and the corresponding parts of the fixed beam 6, and the fixed beam 6 and the movable beam 7 are fixedly connected by bolts.
[0026] The fixed beam 6 and the movable beam 7 can be used as a roof platform to facilitate the installation of roof water tanks, bicycles, and roof tents.
[0027] The fixed beam 6 is installed on the bracket 1 by bolts and nuts.
[0028] Through holes can also be made in the crossbeam 4 and the longitudinal beam 5 for installing toolboxes, side-mounted water tanks and other items.
[0029] This utility model adopts a modular design for the support frame and mounting frame. The support frame can be used as the base of the extension platform, and the mounting frame can be used as a roof platform. It can also be used to install luggage racks, roof tents, water tanks, bicycles and other equipment. It has multiple functions and the mounting frame can be disassembled and assembled as needed, making it highly flexible in use.
