[0002] If the engine compartment temperature of construction machinery such as excavators is too high during operation, it is easy to cause equipment failure or even danger. The conventional solution is to open a large vent on the engine hood to ensure timely heat dissipation in the engine compartment. However, large vents can easily cause stones, leaves, etc. to fall into the engine compartment when the construction machinery is used in harsh working conditions, which can easily damage the structure or components in the engine compartment. In severe cases, flammable objects such as leaves can be ignited, causing the engine compartment to catch fire, thereby burning the machine or causing a safety accident. Utility Model Content

[0004] In order to achieve the above objectives, the present application provides an engine hood, which includes:
[0005] The outer panel of the hood is provided with ventilation holes;
[0006] A protective mesh plate covering the ventilation holes; and
[0007] A connecting plate frame, wherein a plurality of outer frame edges of the connecting plate frame are arranged around the ventilation hole and connected to the hood outer plate, and the plurality of outer frame edges are also connected to the outer edge of the protective mesh plate.

[0012] In some embodiments, the protective mesh plate is welded to the connecting plate frame; and / or the connecting plate frame is welded to the hood outer panel.
[0013] In some embodiments, the connecting plate frame is detachably connected to the hood outer panel; and / or the protective mesh plate is detachably connected to the connecting plate frame.
[0014] In some embodiments, the outer frame edge is provided with a plate frame through hole, the hood outer panel is provided with a hood through hole aligned with the plate frame through hole, and the engine hood also includes a connecting component that detachably connects the plate frame through hole and the hood through hole.
[0015] In some embodiments, the connecting plate frame is further provided with a reinforcing frame edge portion located between the plurality of the outer frame edges, and two ends of the reinforcing frame edge portion are respectively connected to two of the outer frame edges.

[0031] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0032] Reference Figures 1 to 4 , a first exemplary embodiment of the present application provides an engine cover, comprising:
[0033] The hood outer panel 10 is provided with ventilation holes;
[0034] A protective mesh plate 20 is provided to cover the ventilation holes; and
[0035] The connecting plate frame 30 has a plurality of outer frame edges arranged around the ventilation holes and connected to the hood outer plate 10 , and the plurality of outer frame edges are also connected to the outer edge of the protective mesh plate 20 .
[0036] Through the above-mentioned arrangement, the engine hood of the present application is provided with a protective mesh plate 20 covering the ventilation holes on the outer panel 10 of the engine hood. The total flow area of the multiple mesh holes on the protective mesh plate 20 is relatively large, which can ensure that the engine hood still has a good heat dissipation effect, and the opening area of a single mesh hole is greatly reduced relative to the large-sized vents on the existing engine hood. Therefore, it can effectively prevent stones, leaves, etc. from falling into the engine compartment, avoid damage to the structure or components in the compartment, and greatly reduce the risk of fire in the engine compartment, thereby helping to extend the service life of the engine compartment and greatly improve safety. In addition, the connecting plate frame 30 can effectively enhance the deformation resistance of the protective mesh plate 20 and extend the service life of the protective mesh plate 20. Furthermore, compared with the existing engine hood with larger vents, the engine hood of the present application is more complete in structure and beautiful in appearance, which is conducive to increasing the selling point of the machine and the user's desire to buy, and has a good market prospect.
[0037] It should be noted that the mesh holes of the protective mesh plate 20 can be in different shapes such as polygonal holes, circular holes, elliptical holes, waist-shaped holes, etc., and the ventilation holes of the hood outer panel 10 can be waist-shaped holes, square holes, etc., and the present application does not impose any restrictions on this.
[0038] In some embodiments, the connecting plate frame 30 and the protective mesh 20 are located on the inner side of the hood outer panel 10. Under this structure, it is necessary to fix the connecting plate frame 30 and the protective mesh 20 on the inner side of the hood outer panel 10 before the hood is installed to the engine compartment, so as to avoid subsequent difficulties in performing assembly operations in the limited space of the hood.
[0039] In some embodiments, the connecting plate frame 30 and the protective mesh plate 20 are located outside the hood outer panel 10. At this time, the engine hood can be installed to the engine compartment first, and then the connecting plate frame 30 and the protective mesh plate 20 are fixed to the outside of the hood outer panel 10. If the connecting plate frame 30 and the hood outer panel 10, or the connecting plate frame 30 and the protective mesh plate 20 are detachable, then in this embodiment, the connecting plate frame 30 and the protective mesh plate 20 are arranged outside the hood outer panel 10 to facilitate the disassembly and assembly.
[0040] In some embodiments, the connecting plate frame 30, the protective mesh plate 20 and the hood outer panel 10 are stacked in sequence, that is, at this time, the connecting plate frame 30 is connected to the outer peripheral edge of the protective mesh plate 20 toward the wall surface of the hood outer panel 10, so that the protective mesh plate 20 is located between the connecting plate frame 30 and the hood outer panel 10. After the connecting plate frame 30 is connected and fixed to the hood outer panel 10, a certain pressure can be applied to the outer peripheral edge of the protective mesh plate 20, thereby clamping the protective mesh plate 20, which can further improve the connection stability of the protective mesh plate 20.
[0041] In some embodiments, the protective mesh 20, the connecting plate frame 30 and the hood outer panel 10 are stacked in sequence, that is, the connecting plate frame 30 is connected to the outer peripheral edge of the protective mesh 20 away from the wall of the hood outer panel 10, so that the connecting plate frame 30 is located between the protective mesh 20 and the hood outer panel 10. Under this structure, if the protective mesh 20 is to be replaced, the old protective mesh 20 can be directly removed from the connecting plate frame 30 and a new protective mesh 20 can be installed. This disassembly and assembly process does not require the connecting plate frame 30 to be removed from the hood outer panel 10, which is convenient and quick, and can improve the disassembly and assembly efficiency of the protective mesh 20.
[0042] In some embodiments, the inner peripheral walls of the multiple outer frame edges of the connecting plate frame 30 are connected to the outer peripheral edge of the protective mesh plate 20, which is equivalent to embedding and fixing the protective mesh plate 20 in the connecting plate frame 30. At this time, the connecting plate frame 30 and the protective mesh plate 20 can be simultaneously disassembled and assembled on the hood outer panel 10. This method is particularly suitable for the quick disassembly and assembly of the connecting plate frame 30 and the protective mesh plate 20 that are pre-connected into an integral structure.
[0043] In some embodiments, the protective mesh 20 is welded to the connecting plate frame 30; and / or the connecting plate frame 30 is welded to the hood outer panel 10. By adopting the welding method, the connection strength between the protective mesh 20 and the connecting plate frame 30, or between the connecting plate frame 30 and the hood outer panel 10 can be improved, so that the impact of foreign objects with a certain weight such as stones can be more effectively resisted, and the protective mesh 20 or the connecting plate frame 30 can be prevented from falling off, thereby improving reliability.
[0044] In some embodiments, the connecting plate frame 30 is detachably connected to the hood outer panel 10; and / or the protective mesh plate 20 is detachably connected to the connecting plate frame 30. By adopting a detachable connection method, the connecting plate frame 30 or the protective mesh plate 20 can be replaced in time according to actual needs, so that the protective structure is replaceable, thereby meeting the needs of more different protective working conditions. In addition, it can also avoid that the protective structure cannot be repaired after failure, so that the engine hood can have the ability to block foreign objects such as stones and leaves for a long time.
[0045] In some embodiments, reference Figure 4 The outer frame edge of the connecting plate frame 30 is provided with a plate frame through hole, the hood outer panel 10 is provided with a hood through hole aligned with the plate frame through hole, and the engine hood further includes a connecting component 40 that detachably connects the plate frame through hole and the hood through hole, so that the connecting plate frame 30 and the hood outer panel 10 can be disassembled and assembled by disassembling the connecting component 40, and the structure is simple and easy to operate. For example, the connecting component 40 can be a bolt component, etc.
[0046] In some embodiments, the connecting plate frame 30 is also provided with a reinforcing frame edge located between multiple outer frame edges, and the two ends of the reinforcing frame edge are respectively connected to two outer frame edges, which can further strengthen the strength of the connecting plate frame 30. At the same time, the reinforcing frame edge can further improve the deformation resistance of the protective mesh plate 20.
[0047] It should be noted that the present application does not limit the number and arrangement of the reinforcement frame edges. Figure 1 and Figure 2 The connecting plate frame 30 may be provided with a reinforcing frame edge extending in the longitudinal direction, or refer to Figure 4 The connecting plate frame 30 may be provided with a plurality of reinforcing frame edges extending in the transverse direction and spaced in sequence in the longitudinal direction.
[0048] In some embodiments, the opening area of a single mesh of the protective mesh plate 20 is 4 mm 2 Up to 100mm 2 , which can ensure a certain degree of fluidity and take heat dissipation into consideration, and avoid too large openings, so as to block as many foreign objects as possible. In addition, the ratio of the total opening area of all meshes of the protective mesh plate 20 to the opening area of a single vent hole is 1 / 3 to 2 / 3. In this way, even if the opening area of a single mesh hole is small, the total opening area of all meshes of the entire protective mesh plate 20 is not much smaller than that of the vent hole, thereby ensuring that the protective mesh plate 20 has a good heat dissipation effect.
[0049] A second exemplary embodiment of the present application further provides an engine compartment, which includes:
[0050] the aforementioned engine bonnet; and
[0051] The engine is built into the hood.
[0052] Since the above-mentioned engine hood is adopted, the engine compartment of the present application obviously has all the technical effects brought by it, so it will not be repeated here.
[0053] The third exemplary embodiment of the present application also provides an engineering machine, which includes the above-mentioned engine compartment. Similarly, due to the use of the above-mentioned engine hood, the engineering machine of the present application obviously has all the technical effects brought by it, so it will not be repeated here. The present application is not limited to the specific type of engineering machinery, such as excavators, shovels, etc.
