Description

Technical Field

[0001] The utility model relates to the technical field of upper berths on heavy trucks, and specifically relates to a structure for the upper berth on a heavy truck that can be partially multi-directionally flipped. Background Technique

[0002] As a main tool for road transportation, trucks are widely used in various traffic projects. Due to the long driving mileage during long-distance transportation and for the convenience of drivers to rest during transportation, a berth is usually arranged inside the truck cab. In order to make full use of the internal space of the cab, a design of upper and lower berths is adopted. Among them, in order to ensure the safety of the driver during rest and prevent the driver from rolling off the berth, a guardrail is usually arranged at the upper berth.

[0003] The existing CN218949006U heavy truck berth structure solves the problem that the bed body and the guardrail adopt a fixed structure, resulting in the guardrail being unable to be disassembled, occupying a large space and having a large mass. After the threaded cooperation between the screw and the screw hole is separated, the fence frame can rotate 90 degrees clockwise to be parallel to the bed board. The fence frame can be slid into the fence groove along the chute through the slider, which can reduce the use space and facilitate the taking and placing of objects stacked above the bed body. However, there are deficiencies. The existing equipment cannot expand the area and cannot provide stable support for it, with poor use stability. Moreover, the mattress is not stably installed and is inconvenient to use. Therefore, a structure for the upper berth on a heavy truck that can be partially multi-directionally flipped is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a structure for the upper berth on a heavy truck that can be partially multi-directionally flipped, so as to solve the problems mentioned in the above background technique that the heavy truck berth structure cannot expand the area, cannot provide stable support for it, has poor use stability, and the mattress is not stably installed and is inconvenient to use.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A locally multi-directionally flipable structure for the upper berth of a heavy truck, including a support base. A support back frame is fixedly connected to the rear side of the upper end of the support base. A support frame is installed on the upper end of the support base, and a seat cushion is installed on the upper end of the support frame. A storage groove is formed in the inner wall of the support base, and a pull slider is inserted and installed at the edge of the upper end of the support base. The upper end of the pull slider is fixedly connected to the support frame, and a connecting hinge is installed on the front side of the upper end of the support frame. The other side of the connecting hinge is installed with a mounting block, and a second rotating shaft is installed on one side of the mounting block. One end of the second rotating shaft is installed with an auxiliary support frame, and folding storage grooves are formed at both the upper and lower ends of the auxiliary support frame. One side of the inner wall of the folding storage groove is installed with a first rotating shaft, and the other side of the first rotating shaft is installed with a fixed support frame. Screws are inserted and installed on both sides of the inner wall of the fixed support frame, and a support foot pad is fixedly connected to one end of the screw. Positioning splicing slots are formed at the edges of the upper ends of the auxiliary support frame and the support frame, and positioning splicing inserts are inserted and installed in the inner walls of the positioning splicing slots. The upper end of the positioning splicing insert is fixedly connected to the seat cushion. An installation slot is formed on the front side of the support back frame, and an installation rod is fixedly connected to the inner wall of the installation slot. An installation block is sleeved on the outer wall of the installation rod, and a backrest cushion is fixedly connected to one side of the installation block.

[0006] Preferably, the seat cushion is installed in a positioning magnetic splicing manner with the auxiliary support frame and the support frame in the positioning splicing slots through the positioning splicing inserts, and the seat cushion is a folding and split structure.

[0007] Preferably, the backrest cushion is installed in an inserted splicing manner with the support back frame on the outer wall of the installation rod through the installation block.

[0008] Preferably, the shape of the auxiliary support frame matches the shape of the support frame, and the auxiliary support frame is flip-connected to the support frame on the connecting hinge through the mounting block, and the auxiliary support frame is rotationally connected to the mounting block through the second rotating shaft.

[0009] Preferably, the support frames and the storage grooves are distributed in three parallel positions on the support base, and the support frames are slidably connected to the support base through the pull sliders.

[0010] Preferably, the fixed support frame is vertically flip-connected to the folding storage groove through the first rotating shaft, and the support foot pad is screw-lifted and connected to the fixed support frame through the screw.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The multi-directional partial flipping structure of the upper berth of the heavy truck can flip and unfold the auxiliary support frame through the connecting hinge, and can unfold the seat cushion to expand the space, making it more comfortable to use. Moreover, after the auxiliary support frame is unfolded, it can be flipped and extended for support through the fixed support frame, support foot pads and screw rods, with stable use. And when the support structure on one side is damaged, the auxiliary support frame can be flipped through the second rotating shaft to use the other set of support structures for support, while the seat cushion can be magnetically positioned and installed through the positioning splicing inserts and positioning splicing slots to prevent it from shifting, which is convenient to use.
