[0037] As Figures 1-9 shown, in an embodiment of the present utility model, a chassis is provided, which includes a box body 10, a cover plate 20 and two hinge mechanisms 30. The top of the box body 10 is open, and the cover plate 20 is used to open or cover the opening of the box body 10. The two hinge mechanisms 30 are arranged at intervals, and each hinge mechanism 30 is respectively connected to the cover plate 20 and the box body 10. The hinge mechanism 30 includes a first connecting seat 31, a second connecting seat 32 and a connecting component. The first connecting seat 31 is arranged on the cover plate 20, the length direction of the first connecting seat 31 is parallel to the width direction of the cover plate 20, and a slider 33 that can slide along its own length direction is arranged on the first connecting seat 31.

[0038] The present embodiment discloses a chassis and a generator set. When the cover plate 20 is at the maximum opening and closing position, the center of mass of the cover plate 20 is located above the top surface of the box body 10 and close to the top surface of the box body 10. Since part of the cover plate 20 moves to the rear side of the box body 10, the windward area of ​​the inner side of the cover plate 20 becomes smaller, and the wind is not easy to blow the cover plate 20 in the open state, so that the cover plate 20 can still be kept in the open state, avoiding the problem that the open cover plate 20 is easily closed by the wind, improving the windproof and wind-resistant effects of the cover plate 20 and the chassis as a whole, reducing safety hazards, and ensuring the normal use of the chassis. At the same time, the hinge mechanism 30 is not exposed to the outside, which prolongs the service life of the hinge mechanism 30 and ensures the firmness of the connection between the cover plate 20 and the box body 10. At the same time, the long first connecting seat 31 is installed on the cover 20, and the short second connecting seat 32 is installed in the box body 10.

Each reinforcing beam 21 corresponds to a first connecting seat 31, and the first connecting seat 31 is installed on the reinforcing beam 21. The design of the first reinforcing beam 21 can not only play a connecting role for the first connecting seat 31, but also realize the connection between the first connecting seat 31 and the cover plate 20. At the same time, the reinforcing beam 21 will also improve the structural strength of the cover plate 20 and reduce the possibility of deformation of the cover plate 20.

[0040] Furthermore, a first mounting member 40 is provided on the reinforcing beam 21, and the first mounting member 40 includes a first plate body 41 and a second plate body 42 connected to each other. The first plate body 41 is provided on the reinforcing beam 21, and a clearance gap 50 is provided between the second plate body 42 and the reinforcing beam 21.

The first plate body 41 is fastened to the reinforcing beam 21 by bolts, and the second plate body 42 is also fastened to the first connecting seat 31 by bolts. In addition, the design of the clearance gap 50 facilitates the position of the nut 43 to be made free when the second plate body 42 is connected to the first connecting seat 31.

[0041] Furthermore, the first connection seat 31 is provided with a plurality of first through holes, and the second plate body 42 is provided with a plurality of second through holes, each of which corresponds to a first through hole. A plurality of nuts 43 are fixedly provided on the second plate body 42, and the nuts 43 are located in the clearance gap 50, and each of which corresponds to a second through hole. The nuts 43 are fixed to the second plate body 42 by welding, and by fixing the nuts 43 to the second plate body 42 in advance, it is convenient for the operator to quickly install the first connection seat 31 on the second plate body 42.

[0042] In one embodiment, the connecting assembly includes a first connecting arm 34, a second connecting arm 35, and a third connecting arm 36. The two ends of the first connecting arm 34 are respectively hinged to a first connecting seat 31 and a second connecting seat 32.

The two ends of the second connecting arm 35 are respectively hinged to a slider 33 and the second connecting seat 32. The two ends of the third connecting arm 36 are respectively hinged to the first connecting arm 34 and the slider 33. The connecting assembly further includes a fourth connecting arm 37. The two ends of the fourth connecting arm 37 are respectively connected to the third connecting arm 36 and the second connecting seat 32. The structural design of the connecting assembly enables the first connecting seat 31 to have a stronger bearing capacity, better adapt to the weight of the cover plate 20 and the wind resistance effect. The third connecting arm 36 and the fourth connecting arm 37 can also serve as auxiliary supporting arms, further improving the bearing capacity of the hinge mechanism 30.

[0043] In one embodiment, a second mounting member 60 and a third mounting member 70 are provided in the box body 10. The two second connecting seats 32 are respectively arranged on the second mounting member 60 and the third mounting member 70. A third through hole 71 is provided on the third mounting member 70.
