Description

Technical Field

[0001] This utility model relates to the field of truck body technology, and in particular to a truck body structure. Background Technology

[0002] Electric trucks, as an emerging freight vehicle, have significant advantages, including low operating costs: electricity prices are much lower than fuel prices, especially in areas with low electricity prices, which significantly reduces the operating costs of electric trucks. Furthermore, the lightweight design of the truck body can directly reduce vehicle fuel consumption and increase rated load capacity. This is particularly true in the field of new energy vehicles, where the demand for weight reduction in the truck body is even stronger due to the large mass of the batteries themselves.

[0003] To address the aforementioned technical issues, existing patent (CN207931824U) discloses a lightweight all-aluminum structure light truck body, including components such as a floor unit, a roof unit, a column frame unit, a side panel unit, and a rear door unit. The main connecting parts of this utility model's truck body use BOM structure rivets, stainless steel connectors, or stainless steel bolts for connection, avoiding deformation and insufficient strength of welded parts caused by extensive welding of aluminum alloy components, which would affect the overall strength of the truck body. By using an all-aluminum structure design, this utility model's truck body reduces the weight of a light truck body of the same specification by more than 40% compared to a conventional steel truck body.

[0004] In actual use of trucks, there are situations where goods cannot be stacked on top of each other, and existing equipment cannot achieve layered loading of the truck compartment, which greatly reduces the loading capacity of the truck compartment and thus increases transportation costs. Summary of the Invention

[0005] The purpose of this utility model is to provide a truck body structure that solves the problem that in the actual use of trucks, there is a situation where goods cannot be stacked, and existing equipment cannot achieve layered truck bodies, which greatly reduces the loading capacity of the truck body and thus increases transportation costs.

The supporting block is fixedly connected to the column and is located on the side of the column closer to the mounting block. The supporting rod is slidably connected to the supporting block and is located on the side of the supporting block away from the column, and is connected to the extension plate.

[0009] The reinforcing component includes a mounting frame, a reinforcing strip, and a fixing element. The mounting frame is fixedly connected to the extension plate and is located on the side of the extension plate away from the rotation axis. The reinforcing strip is slidably connected to the mounting frame and is located on the side of the mounting frame close to the extension plate, and abuts against the extension plate.

[0020] This utility model provides a truck body structure, including a floor plate 100, columns 101, and a layered assembly. The layered assembly includes a mounting block 102, a rotating shaft 103, an extension plate 104, a support component, a reinforcing component, fixing bolts 105, and a rotating block 106. The support component includes a support block 107 and a support rod 108. The reinforcing component includes a mounting frame 109, a reinforcing strip 110, and a fixing element. The fixing element includes an insert rod 111 and an abutment block 112. This solution solves the problem that in the actual use of trucks, there is a situation where goods cannot be stacked, and existing equipment cannot achieve layered truck bodies, which greatly reduces the loading capacity of the truck body and thus increases transportation costs.

[0021] In this specific embodiment, the uprights 101 are mounted on the base plate 100, and side plates are installed between the uprights 101. A top plate is installed above the uprights 101, thus forming a cargo box. The base plate 100 is mounted on the electric truck and supports the uprights 101. This solution enables the cargo box to be layered, which facilitates the loading of goods that cannot be stacked, increases the loading capacity, and reduces freight costs.

[0022] The mounting block 102 is fixedly connected to the column 101 and located on the side of the column 101 away from the base plate 100. The rotating shaft 103 is rotatably connected to the mounting block 102 and located on the side of the mounting block 102 away from the column 101. The extension plate 104 is fixedly connected to the rotating shaft 103 and located on the side of the rotating shaft 103 away from the mounting block 102. The support member is mounted on the column 101 and supports the extension plate 104. The reinforcing member is mounted on the extension plate 104 and reinforces the extension plate 104. The mounting block 102 is bolted to the column 101. The column 101 has a reinforcing structure to stably support the mounting block 102. The rotating shaft 103... A bearing is installed on the mounting block 102, allowing the rotating shaft 103 to rotate on the mounting block 102. An extension plate 104 is fixedly installed on the rotating shaft 103, allowing the extension plate 104 to rotate on the mounting block 102. There are four extension plates 104, with each pair of extension plates 104 forming a plane. A support member is installed on the column 101, supporting the extension plates 104 and keeping them parallel to the base plate 100. A reinforcing member is installed on the extension plates 104, connecting two extension plates 104 to increase their strength. This allows for layering inside the cargo box, facilitating the loading of goods that cannot be stacked, increasing loading capacity, and reducing freight costs.

[0023] Secondly, the fixing bolt 105 is rotatably connected to the extension plate 104 and is located on the side of the extension plate 104 away from the rotating shaft 103, and is connected to the column 101; the rotating block 106 is fixedly connected to the fixing bolt 105 and is located on the side of the fixing bolt 105 away from the extension plate 104. The fixing bolt 105 is installed on the extension plate 104, and the extension plate 104 has a threaded hole that mates with the fixing bolt 105, so that the fixing bolt 105 can pass through the extension plate 104. The fixing bolt 105 passes through the extension plate 104 and is connected to the column 101, so that the extension plate 104 can be parallel to the column 101, so that the extension plate 104 can be folded when the carriage does not need to be divided. The rotating block 106 is fixedly installed on the fixing bolt 105, and the fixing bolt 105 is driven to rotate by the rotating block 106.

[0024] Meanwhile, the support block 107 is fixedly connected to the column 101 and located on the side of the column 101 closer to the mounting block 102; the support rod 108 is slidably connected to the support block 107 and located on the side of the support block 107 away from the column 101, and is connected to the extension plate 104. The support block 107 is bolted to the column 101. Multiple reinforcing structures are installed on the support block 107 and the column 101. The support rod 108 is slidably installed on the support block 107. The support block 107 has a groove that mates with the support rod 108, allowing the support rod 108 to slide into the support block 107. The extension plate 104 has a groove that mates with the support rod 108, allowing the support rod 108 to be inserted into the extension plate 104, thereby keeping the extension plate 104 parallel to the base plate 100 and enabling the extension plate 104 to support goods.

[0025] Additionally, the mounting frame 109 is fixedly connected to the extension plate 104 and is located on the side of the extension plate 104 away from the rotating shaft 103; the reinforcing strip 110 is slidably connected to the mounting frame 109 and is located on the side of the mounting frame 109 close to the extension plate 104, and abuts against the extension plate 104; the fixing element is installed on the extension plate 104, and the fixing element fixes the reinforcing strip 110; the mounting frame 109 is installed on the extension plate 104 by welding, and the reinforcing strip 110 is slidably installed in the mounting frame 109, so that both sides of the reinforcing strip 110 abut against the extension plate 104 and the mounting frame 109 respectively, thereby making the two extension plates 104 more tightly connected, so that the extension plate 104 can support heavier goods; the fixing element is installed on the extension plate 104, and the fixing element fixes the reinforcing strip 110, so that the reinforcing strip 110 can support the two extension plates 104.

[0026] Finally, the insertion rod 111 is fixedly connected to the expansion plate 104 and located on the side of the expansion plate 104 away from the mounting frame 109, and is connected to the reinforcing strip 110; the abutment block 112 is fixedly connected to the insertion rod 111 and located at the end of the insertion rod 111 away from the reinforcing strip 110. The insertion rod 111 is slidably mounted on the expansion plate 104, so that the insertion rod 111 passes through the expansion plate 104 and connects with the reinforcing strip 110, thereby preventing the reinforcing strip 110 from moving. The abutment block 112 is fixedly mounted on the insertion rod 111, and the abutment block 112 is connected to a magnet, so that the insertion rod 111 is stably mounted on the expansion plate 104.

[0027] Using a truck body structure according to this embodiment, when transporting goods that cannot be stacked, the support rod 108 is first inserted into the support block 107. The fixing bolt 105 is driven to rotate by the rotating block 106, allowing the extension plate 104 to rotate. This connects the extension plate 104 to the support rod 108, keeping the extension plate 104 parallel to the bottom plate 100. At this time, the reinforcing strip 110 is inserted into the mounting frame 109, and the reinforcing strip 110 is fixed by the insert rod 111. This allows the extension plate 104 to support the goods, thus enabling the cargo box to be layered internally. This facilitates the loading of goods that cannot be stacked, increases the loading capacity, and reduces freight costs.
