Technical Field

[0001] The utility model relates to the field of vehicle equipment, in particular to an articulated rear window protective cover for trucks. Background Art

[0002] When an articulated truck is transporting bulk materials such as ore, the distance between the front baffle or the front brim of the truck cargo box and the rear window of the cab is large, which causes the loose materials to easily fall to the rear window of the cab during loading and transportation, resulting in damage to the rear window glass of the cab. Based on this, the existing rear windows of articulated trucks mostly adopt a protective structure for the rear window of the truck cab disclosed in CL200600894S, which mainly consists of a frame and a rib net arranged inside the frame.

[0003] This type of existing protective structure, when faced with falling block ore, the ore often has great kinetic energy, causing the reinforcement mesh to be easily deformed and damaged. In some working conditions, the ore can easily cause the reinforcement mesh to deform and directly contact the rear window, causing the rear window to break.

[0004] Therefore, it is necessary to improve the protective structure of the rear window of the articulated truck to solve the problems existing in the prior art. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an articulated truck rear window protective cover, which effectively solves the problems existing in the prior art by optimizing the design of the protective cover structure.

[0007] Furthermore, the connecting portion is configured as a mounting plate that is folded outward.

[0008] Further, the mounting plate is connected to the truck via threaded fasteners.

[0009] Furthermore, the width of the support plate area is greater than or equal to 1 centimeter.

[0010] Furthermore, the annular plate portion is provided with supporting ribs at least on the inner side of the top.

[0011] Furthermore, the mesh plate portion and the ring plate portion are integrally connected by stamping, and the protective cover further comprises a reinforcing support plate welded to the inner side of the ring plate portion, and the reinforcing support plate is welded with the supporting ribs.

[0012] Alternatively, the mesh plate portion and the ring plate portion are connected by welding.

[0013] Furthermore, the edge of the ring plate portion protrudes from the mesh plate portion, or the edge of the ring plate portion is flush with the mesh plate portion.

[0014] Furthermore, the top plate of the annular plate portion is inclined obliquely downward toward the mesh plate portion.

[0015] Furthermore, the cross section of the through hole is configured to be hexagonal.

[0024] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0025] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0028] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0029] In the present utility model, if Figure 1-5As shown, there is provided an articulated rear window protective cover for trucks, comprising a ring plate portion 2 and a mesh plate portion 3 connected to the ring plate portion 2, wherein the side of the ring plate portion 2 facing away from the mesh plate portion 3 is provided with a connection portion that can be connected to the truck 1, the mesh plate portion 3 is divided into a mesh area 4 and a support plate area 5 surrounding the mesh area 4, the mesh plate portion 3 is provided with through holes at intervals in the mesh area 4, and the mesh plate portion 3 is connected to the ring plate portion 2 in the support plate area 5.

[0030] When the protective cover of the utility model is in use, the edge of the ring plate part 2 is connected to the truck 1, so that the ring plate part 2 surrounds the outside of the rear window, and the ring plate part 2 supports the mesh plate part 3 to protect the rear window. The present application adopts a plate-like structure to open holes in the mesh plate part 3. Compared with the existing mesh reinforcement weaving form, the mesh plate of the utility model has a stable shape, is not easy to deform and damage, and has stronger impact resistance. Moreover, by setting the support plate area 5 in the mesh area 4, the structure at the edge of the mesh plate part 3 and the connection position of the ring plate part 2 can be stable, with high strength and not easy to deform and damage. Moreover, the utility model forms an integral plate-like area with an L-shaped cross-section at this position after connecting the support plate area 5 to the ring plate part 2, so that the edge of the mesh plate part 3 can form an impact-resistant area with a certain support strength, so that when the ore falls from a high place, the edge area of ​​the mesh plate part 3 that is easily directly impacted by the ore has better anti-deformation ability.

[0031] In a preferred embodiment, for the structure of the utility model, further specifically, as shown in the figure, the connecting portion is provided as a mounting plate 6 folded outward. As shown in the figure, it is convenient to connect the mounting plate 6 to the truck 1 from the outside of the ring plate 2, and the connecting portion is provided as a folded mounting plate 6, which further improves the anti-bending ability of the ring plate at the connecting portion.

[0032] As a preferred embodiment, regarding the installation method of the mounting plate 6, more specifically, the mounting plate 6 is connected to the truck 1 via threaded fasteners. Figure 1 and 2 As shown, the threaded fasteners include bolts 7 and washers 8 , and the bolts 7 connect and fix the mounting plate 6 to the truck 1 .

[0033] The connection method of the mounting plate 6 to the truck 1 is not limited to the method of threaded fasteners. In an optional embodiment, other forms may also be used, for example, the mounting plate 6 is directly welded to the truck 1.

[0034] In a preferred embodiment, a further optimization setting of the utility model is that the width of the support plate area is greater than or equal to 1 cm. By controlling the width of the support plate area, it is possible to ensure that the mesh plate portion has sufficient structural strength to improve the anti-impact deformation capability of the protective cover.

[0035] In a preferred embodiment, a further optimized configuration of the utility model is that the annular plate portion 2 is provided with supporting ribs 9 at least on the inner side of the top.

[0036] By arranging supporting ribs 9 on the inner side of the ring plate portion 2 , the bending resistance of the ring plate portion 2 can be further improved.

[0037] Regarding the structure of the protective cover, in a preferred embodiment, as Figure 5 As shown, to be more specific, the mesh plate portion 3 and the ring plate portion 2 are integrally stamped and connected, and the protective cover further includes a reinforcing support plate 10 welded to the inner side of the ring plate portion 2, and the reinforcing support plate 10 is welded with the supporting ribs 9.

[0038] As shown in the figure, a relatively low thickness steel plate (thickness selected from 0.5mm to 2mm) can be used to facilitate bending and forming the plate. By providing a separate reinforcing support plate 10, after the reinforcing support plate 10 is welded with the supporting ribs 9, the reinforcing support plate 10 can be welded to the inner side of the ring plate portion 2, so that it is not only convenient to install and fix the supporting ribs 9, but also the strength of the ring plate portion 2 can be further improved by reinforcing the support plate 10.

[0039] Or in an optional embodiment, for the structural form of the mesh plate portion 3 and the ring plate portion 2, further specifically, as Figure 4 As shown, the mesh plate portion 3 and the ring plate portion 2 are welded and connected. In this way, the mesh plate portion 3 and the ring plate portion 2 can be processed separately, which is convenient for processing the two. In some embodiments, the strength and thickness of the mesh plate portion 3 and the ring plate portion 2 can be selected differently to enhance the structural strength of the ring plate portion 2, further improving the anti-deformation ability of the entire device.

[0040] In a preferred embodiment, a further optimized setting of the utility model is that the edge of the ring plate portion protrudes from the mesh plate portion 3, or the edge of the ring plate portion 2 is flush with the mesh plate portion 3. In this way, the mesh plate portion 3 does not protrude from the ring plate portion 2. Compared with the solution in which the edge of the mesh plate portion 3 protrudes from the ring plate portion 2, the utility model can reduce the probability of the edge of the mesh plate portion 3 being impacted when the ore impacts the edge of the mesh plate portion 3, and further improve the stability of the entire device.

[0041] In a preferred embodiment, a further optimized setting of the utility model is that the top plate of the ring plate portion 2 is inclined downwardly toward the mesh plate portion 3. Figure 5 As shown, when the ore impacts the top of the ring plate 2 from top to bottom, the inclined extending portion of the ring plate 2 can be used to guide the movement of the ore, thereby reducing the impact on the top of the ring plate 2.

[0042] In the illustrated embodiment, with respect to the structure of the mesh plate portion 3 of the present invention, more specifically, the cross section of the through hole is configured to be hexagonal.

[0043] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0044] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
