Description

Technical Field

[0001] This utility model belongs to the technical field of wrecker vehicles, specifically referring to a new type of side beam for wrecker vehicles. Background Technology

[0002] As a core piece of equipment for clearing disabled vehicles and providing emergency rescue, the structural stability of the flatbed of a tow truck directly affects the efficiency of rescue operations and the safety of transportation. In existing technologies, the tow truck's carrying system typically consists of a main board and a rear hydraulic tilting tailgate, which are hinged together by a side beam tilting shaft to meet the operational requirements of the tailgate tilting to the ground and facilitating the loading and unloading of disabled vehicles.

[0003] However, traditional side beam designs have structural flaws: to accommodate the tipping action of the tailgate, a gap for assembly and movement is generally reserved at the connection between the main board and the tipping shaft of the tailgate side beam. While this gap does not affect basic operation under no-load conditions, it disrupts the overall load-bearing continuity of the flatbed when carrying loads such as disabled vehicles. When heavy-duty vehicles drive onto the flatbed or encounter road bumps during transport, stress concentration and localized deformation easily occur at the gap, causing slight swaying or uneven stress on the flatbed. This not only reduces load-bearing stability but also accelerates wear on the tipping shaft and side beams over long-term use, potentially leading to structural fatigue damage and posing a potential risk to the safety of rescue operations.

[0004] Meanwhile, as the demand for obstacle removal becomes more demanding and frequent, the stability issues caused by gaps in traditional side beams are becoming increasingly prominent, making it difficult to meet the high strength and reliability requirements of modern rescue structures. Therefore, there is an urgent need to develop a new type of side beam structure that can eliminate the potential risks of gaps at the tilting axis and improve the overall load-bearing stability of the flat plate. Utility Model Content

[0005] The present invention aims to at least solve the problem that the main board and tailboard of the flatbed clearing vehicle have a gap at the tipping shaft, which causes the main board and tailboard to deform locally due to stress concentration when carrying a heavy fault vehicle, and that this gap can cause the flatbed to experience mixed movement or uneven stress.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes a novel side beam for a tow truck, including a main board mounted on the tow truck on one side and a tail plate hinged to the main board on the other side. A first docking plate extends from the side of the main board near the tail plate, and a second docking plate extends from the side of the tail plate opposite to the main board. When the main board and the tail plate are unfolded, the first docking plate and the second docking plate are seamlessly joined together.

[0007] Furthermore, the heights of the first docking plate and the second docking plate are respectively half that of the main board and the tail plate. After the first docking plate and the second docking plate are docked, a U-shaped groove is formed, and the U-shaped groove covers the hinge position of the main board and the tail plate.

[0008] Furthermore, the upper edge of the motherboard near the hinge position is provided with a 45° chamfer, and the tail plate is also provided with a 45° chamfer on the side near the motherboard, so that the chamfers coincide after the motherboard and the tail plate are connected.

[0009] The beneficial effects of this utility model using the above structure are as follows: a first docking plate and a second docking plate extend from the opposite surfaces of the main board and the tail board, respectively. When closed, the movement of the tail board is not restricted, and when unfolded, the two dock to form a stable support, avoiding the problems of local deformation under heavy load or poor stability due to uneven force due to shaking.

[0012] 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.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] Example 1:

[0015] As per the instruction manual Figure 1-2 As shown, a novel side beam for a tow truck includes a main board 1 mounted on the tow truck on one side, and a tail plate 2 hinged to the main board 1 on the other side. The upper edge of the main board 1 has a 45° chamfer near the hinge position, and the tail plate 2 also has a 45° chamfer on the side near the main board 1. After the main board 1 and the tail plate 2 are joined, the chamfers overlap. A first docking plate 3 extends from the side of the main board 1 near the tail plate 2, and a second docking plate 4 extends from the side of the tail plate 2 opposite to the main board 1. After the main board 1 and the tail plate 2 are unfolded, the first docking plate 3 and the second docking plate 4 are joined without gaps. The heights of the first docking plate 3 and the second docking plate 4 are respectively half of the heights of the main board 1 and the tail plate 2. After the first docking plate 3 and the second docking plate 4 are joined, a U-shaped groove is formed, which encloses the hinge position of the main board 1 and the tail plate 2.

[0016] In specific implementation of this utility model, when the main board 1 and the tail plate 2 are closed, the first docking plate 3 and the second docking plate 4 are separated and perpendicular, each being half the height of the main board 1 and the tail plate 2, respectively. This does not affect the movement of the tail plate 2 on the main board 1. When the tail plate 2 is unfolded on the main board 1 and is at the same horizontal plane as the main board 1, the first docking plate 3 and the second docking plate 4 make contact without gaps, and work together with the main board 1 and the tail plate 2 to partially wrap the rotating shaft. At this time, there are no gaps between the main board 1 and the tail plate 2. When a faulty vehicle is loaded, the first docking plate 3 and the second docking plate 4 make seamless connection, which perfectly overcomes the problem of stress concentration. The tail plate 2 can also connect with the main board 1 more stably without shaking.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0018] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
