Technical Field

[0001] The utility model relates to the technical field of generator set casings, and particularly relates to a variable-frequency generator set. Background Art

[0002] For some small variable-frequency generator sets, the product features are light weight, small structure, and convenient to carry and use. The all-plastic casings of variable-frequency generator sets are generally divided into two types. One is the casing with a handle structure. Since the handle plays the role of a skeleton, there is no need to additionally design a metal bracket inside the casing, and the overall strength requirements can be met.

[0003] The other is the casing with an upper cover structure. Such a casing needs to design a skeleton inside to disperse the force. Otherwise, the whole machine casing is prone to falling apart and deforming. At the same time, the casings of existing small variable-frequency generator sets are usually designed with a handle to facilitate the user to pull the whole machine. The connecting seat of the handle is generally directly installed on the panel seat. Therefore, when using the handle, it is easy to cause changes at the joint of the panel seat with the side cover plate and the upper cover plate, and problems such as deformation of the casing are likely to occur. Therefore, how to avoid the deformation problem of the above-mentioned casing with an upper cover structure is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0004] Aiming at the defects in the prior art, the purpose of the utility model is to provide a variable-frequency generator set, which redistributes the force of the whole machine by redesigning the casing structure and the installation position of the handle connecting seat, so as to avoid the deformation of the casing.

[0005] To achieve the above purpose, the utility model provides a variable-frequency generator set, including a bottom plate; a panel seat arranged on the bottom plate; a rear cover plate arranged on the bottom plate; two cross bars respectively arranged on the left and right sides of the panel seat, with both ends of each cross bar connected to the panel seat and the rear cover plate respectively; two connecting seats, each connecting seat being arranged on a corresponding cross bar, the connecting seat being close to the panel seat, a connecting arm being rotatably arranged on the connecting seat, and the connecting arm extending out of the panel seat; and a handle arranged on the front side of the panel seat and connected to the two connecting arms respectively.

[0006] Preferably, it further includes a fuel tank arranged between the two cross bars and connected to the two cross bars respectively.

[0007] Preferably, at least two jacks are arranged on the side wall of one cross bar facing the other cross bar, and tongues matching the jacks are arranged on the circumferential side wall of the fuel tank.

[0008] Preferably, an operation block is arranged on the top of the panel seat, a gap is formed between the operation block and the panel seat, and the operation block is connected to the two cross bars respectively.

[0009] Preferably, the top of the panel seat is recessed to form a first recessed portion, the first recessed portion is provided with two mounting holes, and the bottom of the operating block is provided with two connecting columns, each of the connecting columns is arranged in the corresponding mounting hole, and each of the connecting columns is connected to the corresponding cross bar.

[0010] Preferably, a side of the rear cover plate facing away from the panel seat is recessed to form a second recessed portion, and the second recessed portion is close to the top of the rear cover plate.

[0011] Preferably, the cross bar is made of plastic material.

[0012] Preferably, it further comprises two side cover plates, wherein the side cover plates are located on the outer sides of the cross bar, and each of the side cover plates is connected to the cross bar on a corresponding side.

[0038] Such as Figures 1-12As shown in the figure, in an embodiment of the present utility model, a variable-frequency generator set is provided, which includes a bottom plate 10, a panel seat 20, a rear cover plate 30, two cross bars 40, two connecting seats 50 and a handle 60. The panel seat 20 and the rear cover plate 30 are both installed on the bottom plate 10. The two cross bars 40 are respectively arranged on the left and right sides of the panel seat 20. The two ends of the cross bar 40 are respectively connected to the panel seat 20 and the rear cover plate 30. The connection point between the cross bar 40 and the panel seat 20 is close to the top of the panel seat 20, and the connection point between the cross bar 40 and the rear cover plate 30 is close to the top of the rear cover plate 30. Each connecting seat 50 is arranged on a corresponding cross bar 40. The connecting seat 50 is close to the panel seat 20. A connecting arm 51 is rotatably arranged on the connecting seat 50. A through hole 22 for the connecting arm 51 to pass through is provided on the panel seat 20. After the connecting arm 51 passes through the through hole 22, it extends outside the panel seat 20. The handle 60 is arranged on the front side of the panel seat 20 and is respectively connected to the two connecting arms 51. Among them, the structure of the connecting seat 50 is prior art and will not be described in detail in this embodiment.

[0039] In a variable-frequency generator set disclosed in this embodiment, two cross bars 40 are designed to connect the panel seat 20 and the rear cover plate 30. Under the interaction of the bottom plate 10, the panel seat 20, the rear cover plate 30 and the two cross bars 40, a firm main body framework can be formed. On the premise of ensuring the structural strength, the use of structural parts is reduced, the overall weight is reduced, and the manufacturing cost is also saved. At the same time, by installing the connecting seat 50 on the cross bar 40, since the connecting seat 50 is not connected to the panel seat 20, when the handle 60 is used, the acting force of the handle 60 will be shared by the connecting seat 50 and the cross bar 40 to the panel seat 20 and the rear cover plate 30. In this way, the panel seat 20 will not be directly stressed, so that the whole machine is stressed more evenly and the deformation of the shell is avoided.

[0040] In one embodiment, the variable-frequency generator set further includes a fuel tank 70. The fuel tank 70 is arranged between the two cross bars 40 and is respectively connected to the two cross bars 40. By installing the fuel tank 70 on the two cross bars 40, there is no need to additionally design structural parts to support the fuel tank 70, the use of structural parts is reduced, the overall weight is reduced, and the manufacturing cost is also saved.

[0041] Specifically, two jacks 41 are provided on the side wall of the cross bar 40 facing the other cross bar 40. Insert tongues 71 matching the jacks 41 are provided on the circumferential side wall of the fuel tank 70, and the total number of the first insertions is four. With the mutual cooperation of the insert tongues 71 and the second jacks 41, the fuel tank 70 can be firmly installed between the two cross bars 40 without the need to additionally use structural parts and fasteners. At the same time, when the fuel tank 70 is assembled to the two cross bars 40, the open structure is more conducive to improving the assembly speed of the fuel tank 70.

[0042] In one embodiment, an operation block 80 is provided on the top of the panel base 20. A gap 90 is formed between the operation block 80 and the panel base 20. The operation block 80 is respectively connected to two cross bars 40. Specifically, a first recessed portion 21 is formed by recessing the top of the panel base 20. Two mounting holes 23 are provided on the first recessed portion 21. Two connecting columns 81 are provided at the bottom of the operation block 80. Each connecting column 81 is arranged in a corresponding mounting hole 23, and each connecting column 81 is connected to the corresponding cross bar 40 by a bolt.

[0043] When carrying or moving the variable frequency generator set, the user can lift the variable frequency generator set by reaching into the gap 90 with the hand and lifting the operation block 80. By installing the operation block 80 on the two cross bars 40, the cross bars 40 will also disperse the acting force to the panel base 20 and the rear cover 30, so that the whole machine is more evenly stressed and the deformation of the shell is avoided.

[0044] In one embodiment, a second recessed portion 31 is formed by recessing the side of the rear cover 30 facing away from the panel base 20. The second recessed portion 31 is close to the top of the rear cover 30. By designing the second recessed portion 31, the two hands of the user can respectively reach into the gap 90 and the second recessed portion 31, so that the variable frequency generator set can be lifted with both hands, thus improving the safety during carrying and moving.

[0045] In one embodiment, the cross bar 40 is made of plastic material. Since various grooves and ribs are designed on both the panel base 20 and the rear cover 30, the structural strength of the panel base 20 and the rear cover 30 is relatively high. By using the plastic-made cross bar 40 to connect the panel base 20 and the rear cover 30, not only the structural strength of the whole machine is satisfied, but also the weight of the whole machine is reduced.

[0046] In one embodiment, the variable frequency generator set further includes an upper cover 110 and two side covers 100. The side covers 100 are located outside the cross bars 40. Each side cover 100 is connected to the corresponding cross bar 40 on one side. The side covers 100 are respectively connected to the bottom plate 10, the panel base 20 and the rear cover 30. The upper cover 110 is respectively connected to the panel base 20, the rear cover 30 and the two side covers 100.

[0047] The panel base 20 and the bottom plate 10, the rear cover 30 and the bottom plate 10, the side cover 100 and the panel base 20, the side cover 100 and the rear cover 30, the upper cover 110 and the panel base 20, the upper cover 110 and the rear cover 30, and the upper cover 110 and the side cover 100 are all assembled by using the connection forms of snap connection and bolts. At the same time, by installing the side cover 100 on the corresponding cross bar 40 on one side, the shell structure of the whole machine is made more firm.
