Wherein the first connector 20 is provided on the inner side of the housing and is used to connect with the fastener 300. The first connecting member 20 includes a first plate 21, a middle portion of the first plate 21 is recessed inward to form a receiving recess 212, and an edge of the first plate 21 is adhesively connected to an inner wall of the housing 10.

With the technical solution of the present embodiment, the first plate 21 is provided with the receiving recess 212, and when the first plate is connected to the fastening member 300, the fastening member 300 can be hidden in the receiving recess 212. The structure prevents the fastener 300 from being exposed out of the hood body 10, so that the hood is more attractive, and prevents a driver from scratching the hood, thereby reducing the rusting condition of the fastener 300. Meanwhile, the first plate body 21 and the cover body 10 are connected together by adhesion, so that the requirement on manufacturing precision is low. Therefore, the technical scheme of the embodiment overcomes the defects that the hood of the excavator in the prior art is poor in aesthetic property and high in assembling precision requirement.

It should be noted that the above-mentioned "bonding" means joining two structures together by using an adhesive. Therefore, the above-mentioned bonding includes bonding the cover 10 to the first plate 21 with an adhesive, and bonding the cover 10 to the first plate 21 with its adhesiveness after partially heat-melting the cover 10 made of plastic.

Further, the first connection hole 211 is located on the bottom wall of the accommodating recess 212.

Further, after the first plate 21 is adhered to the inner surface of the cover 10, the receiving recess 212 and the inner surface of the cover 10 form a closed space, and the second plate 22 is disposed in the closed space.

As shown in fig. 8, in the present embodiment, a coupling nut 23 is provided on a surface of the second plate 22 facing the cover 10 at a position corresponding to the second coupling hole 221. Specifically, the coupling nut 23 is fixedly coupled to a surface of the second plate body 22, and is adapted to be engaged with the bolt described above. The first connection hole 211, the second connection hole 221 and the threaded hole of the connection nut 23 are concentrically arranged, so that the bolt can be screwed into the connection nut 23 after passing through the first connection hole 211 and the second connection hole 221, and the cover 10 is connected with the hinge 100.

As can also be seen in fig. 8, the above-mentioned receiving recess 212 also serves to facilitate the provision of the coupling nut 23.

Of course, the first connector 20 and the bolt may be engaged with each other in other manners, for example, the second connection hole 221 may be directly processed into a screw hole, and in this case, the connection nut 23 may not be provided.

Preferably, the first plate body 21 and the second plate body 22 are connected by bonding. Specifically, the second plate 22 is bonded to the bottom wall of the accommodation recess 212 of the first plate 21.

In this embodiment, the cover 10 and the second connecting member 30 are also connected together by adhesion, so that no fastener is left on the outer surface of the cover 10, so that the outer surface of the cover 10 forms a complete surface, and the aesthetic property of the cover 10 is higher. Meanwhile, since no fastener is used for connection, the manufacturing precision requirements of the cover 10, the first connecting piece 20 and the second connecting piece 30 are low, and the field assembly is easier.

As shown in fig. 2 and fig. 6, in the technical solution of the present embodiment, the second connecting member 30 includes a connecting strip 31 and a third plate 32, the connecting strip 31 is connected to the edge of the cover 10 by adhesion, the third plate 32 is connected to the connecting strip 31, a sliding slot 321 is provided on the third plate 32, and an end of the support rod 200 facing the cover 10 is disposed in the sliding slot 321. Specifically, the connecting strip 31 has a long bar-shaped structure and is bonded to the inner side wall of the edge of the cover 10. Of course, the connecting strips 31 can be arranged at other positions, for example, at the middle of the cover 10 by adhesive bonding. The plane of the third plate 32 is parallel to the plane of the opening and closing direction of the cover 10. As can be seen from fig. 6, the sliding groove 321 includes two groove sections, a first groove section extends in a direction substantially the same as a side edge of the cover 10, and a second groove section extends downward at an angle to the first groove section. When the cover 10 is opened, the ends of the support rods 200 can slide in the first groove sections, and when the support rods 200 slide into the second groove sections, the cover 10 can be supported to be kept at a certain angle.

As shown in fig. 6, in the solution of the present embodiment, the end of the connecting bar 31 is provided with a locking structure 400.
