Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to a chassis for a generator set. Background Art

[0002] The generator set includes a chassis, an engine disposed in the chassis and used to convert the internal energy of the fuel into mechanical energy, and a generator disposed in the chassis and used to convert the mechanical energy transmitted by the engine into electrical energy. The chassis includes a box body and a box cover. In order to facilitate opening and closing the box cover, one side of the box body is usually hinged to one side of the box cover.

[0003] At present, the box body and the box cover are usually hinged by hinges. However, in order to increase the operating space of the box body after the box cover is opened and the sealing degree of the joint between the box cover and the box body after the box cover is closed, it is required that the box cover can be moved to the rear side of the box body after the box cover is opened. Therefore, one connecting plate of the hinge is usually fixedly connected to the box body, and the other connecting plate is connected to the box cover and extends in a direction away from the center line of the box cover, so that the box cover needs to extend a certain distance, which in turn makes the box cover larger in size.

[0037] like Figure 1-5 As shown, the utility model provides a box for a generator set, including a box body 110 provided with an opening and a box cover 120 provided at the opening of the box body 110. Specifically, the box cover 120 includes a frame and a cover plate.

[0038] The generator chassis provided in the present invention also includes a connecting structure, which is used to hinge the first side of the box cover 120 with the first side of the box body 110, and the connecting structure includes a first connecting element 210, a second connecting element 220 and a rotating shaft 230.

[0039] The first connecting element 210 is fixedly connected to the box body 110. The second connecting element 220 is L-shaped, the first end of the second connecting element 220 extends toward the middle of the box cover 120 and is fixedly connected to the box cover 120, and the second end extends toward the direction close to the box body 110. Either end of the first connecting element 210 and the second end of the second connecting element 220 are sleeved on the rotating shaft 230, and at least one of the first connecting element 210 and the second connecting element 220 is rotatably connected to the rotating shaft 230. Specifically, in this embodiment, the first connecting element 210 is sleeved on the first end of the rotating shaft 230, and the second connecting element 220 is sleeved on the second end of the rotating shaft 230.

[0040] Specifically, it also includes a third connecting element 240, and the second connecting element 220 is sleeved on the rotating shaft through the third connecting element 240. Specifically, the second end of the second connecting element 220 is fixedly connected to the third connecting element 240, and one end of the third connecting element 240 away from the first end of the second connecting element 220 is sleeved on the rotating shaft.

[0041] In this embodiment, by setting the second connecting element 220 to be L-shaped and making the first end of the second connecting element 220 extend toward the middle of the box cover 120, it is not necessary for the box cover 120 to extend a distance outside the box body 110 to connect with the second connecting member, thus reducing the volume of the box cover 120. At the same time, since the second connecting element 220 is L-shaped, the hinge center line of the box body 110 and the box cover 120 must be located at the rear side of the box body 110, so that when the box cover 120 is opened, the box cover 120 will inevitably move to the rear side of the box body 110, and will not affect the operating space of the box body 110.

[0042] In one embodiment, a length-adjustable support element 310 is further included, and the support element 310 is disposed in the box body 110, and a first end of the support element 310 is hinged to the box body 110, and a second end of the support element 310 is hinged to the box cover 120. The support element 310 is provided to support the box cover 120 after it is opened, so as to facilitate operation.

[0043] Preferably, the support element 310 is a retractable elastic element. Thus, after the lock of the box cover 120 is released, the box cover 120 is automatically opened under the elastic force of the elastic support element 310, and the box cover 120 can be automatically kept at a certain opening angle under the elastic force of the elastic support element 310, so as to facilitate the opening of the box cover 120.

[0044] Specifically, the support element 310 may be a gas spring, an elastic support rod, etc. Preferably, the support element 310 is a gas spring.

[0045] Preferably, a plurality of support elements 310 are provided, and the plurality of support elements 310 are arranged in sequence and spaced apart along the length direction of the box body 110 to improve the support stability of the box body 110 and reduce the elasticity requirement for a single support element 310. In addition, the uniformity of the support force applied to the box cover 120 can also be improved.

[0046] Preferably, a plurality of connection structures are provided, and the plurality of connection structures are sequentially spaced apart along the length direction of the box body 110 , so as to improve the stability and reliability of the connection between the box cover 120 and the box body 110 .

[0047] Preferably, one end of the first connecting element 210 facing the middle of the box body 110 is connected to the rotating shaft 230, and the other end extends toward the direction close to the box cover 120. By connecting the one end of the first connecting element 210 facing the middle of the box body 110 to the rotating shaft 230, the distance between the hinge center line of the box body 110 and the box cover 120 and the box cover 120 is increased, thereby further improving the operating space of the box body 110 after the box cover 120 is opened and the sealing degree of the joint between the box cover 120 and the box body 110 after the box cover 120 is closed.

[0048] In one embodiment, a locking structure is further included. The locking structure has a locked state and an unlocked state. The locking structure includes a locking element 410 , a locking slider 420 and an operating handle 430 .

Preferably, the locking element 410 is a U-shaped member, and the two free ends of the U-shaped member are fixedly connected to the box body 110 or the box cover 120. In this embodiment, the two free ends of the U-shaped member are fixedly connected to the box cover 120.

[0050] The locking slider 420 is disposed on the second side of the other of the box body 110 and the box cover 120 and is slidably connected thereto, and the locking slider 420 has a first position and a second position. Specifically, when the locking slider 420 is in the first position, the locking slider 420 is inserted into the locking hole, so that the locking structure is in a locked state; when the locking slider 420 is in the second position, the locking slider 420 moves out of the locking hole, so that the locking structure is in an unlocked state. In this embodiment, the locking element 410 is disposed on the box cover 120, and the locking slider 420 is disposed on the box body 110.

[0051] The first end of the operating handle 430 is fixedly connected to the locking slider 420, and the second end extends outside the box body 110 or the box cover 120. The operating handle 430 drives the locking slider 420 to reciprocate between the first position and the second position, so that the locking slider 420 is located in the locking hole or moves outside the locking hole, so that the locking structure switches between the unlocked state and the locked state.

[0052] The locking structure provided in this embodiment has a simple structure, reasonable design and convenient operation.
