Description

Technical Field

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

[0002] To facilitate mobility, portable generators mount the assembled generator set on a frame equipped with wheels for easy movement. Existing portable generator frames typically feature two crossbeams at the bottom of the frame, supporting the generator set. However, due to the generator set's weight, relying solely on these two beams may not be sufficient to support it. This poses a risk of it falling during transport or handling, and the impact of a fall could potentially break the beams. Therefore, to address this issue, this solution proposes a generator set frame. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the present invention aims to provide a generator set frame to improve the support strength of the frame structure and ensure the support stability of the overall structure.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A generator set frame comprises a frame located outside the generator, wherein a first crossbeam and a second crossbeam arranged in parallel are provided at the bottom of the frame, and two connecting plates arranged in parallel are provided between the first crossbeam and the second crossbeam.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] This solution adds two connecting plates between the first crossbeam and the second crossbeam. The two connecting plates can connect the first crossbeam and the second crossbeam to form a whole, and can evenly distribute the load on the first crossbeam and the second crossbeam, thereby enhancing the overall load-bearing strength of the crossbeams and solving the current problems of insufficient load-bearing strength and uneven force of the crossbeams. In addition, in order to prevent the risk of the generator falling during transportation, an anti-fall structure is also provided on the supporting structure. The connecting plates of this solution can be connected to the anti-fall structure, and can play a supporting and connecting role for the anti-fall structure.

[0008] As a preferred embodiment of the present invention, the connecting plate includes a first support plate and a second support plate formed by bending the lower side of the first support plate, a reinforcing rib is formed at the corner between the first and second support plates, and two ear plates protrude upward from the upper side of the first support plate. In this solution, the two ear plates are connected to the anti-fall structure. By adopting the ear plate structure for connection, not only can a larger connection area be provided, thereby enhancing the firmness and stability of the connection, but the ear plates can also serve as reinforcement components to enhance the overall strength of the main structure. At the same time, the second support plate bent at the lower side of the first support plate and the reinforcing rib provided at the corner between the first and second support plates can further increase the overall strength of the connecting plate and improve stability.

[0009] As a preferred embodiment of the present invention, the first crossbeam includes a straight portion, both sides of which are bent downward to form a first bent portion, and the lower sides of the two first bent portions are respectively bent outward to form a second bent portion. The structure of the second crossbeam differs from that of the first crossbeam in that the second bent portion on the side of the second crossbeam away from the connecting plate is bent upward to form a hem. In this solution, by flanging the second bent portion of the second crossbeam upward, the load-bearing strength of the crossbeam is increased while the material wall thickness can be reduced while maintaining the same load-bearing strength, thereby reducing costs.

[0010] As a preferred embodiment of the present invention, reinforcement plates are installed on both sides of the frame bottom. The reinforcement plates extend toward both ends of the frame near the center of gravity of the engine block. In this solution, by installing reinforcement plates on both sides of the frame bottom, the localized area of ​​the frame bottom, where stress is more concentrated, can be further strengthened, thereby further improving the overall structural strength of the frame and ensuring structural stability.

[0011] As a preferred embodiment of the present invention, the frame is provided with two rollers at the bottom, and a first crossbeam is located on a side away from the rollers. Two legs are detachably connected to the first crossbeam, and the two legs and the two rollers can be supported on the ground. In this embodiment, the two legs provided on the first crossbeam can be supported on the ground together with the two rollers. To reduce the weight of the generator, the external frame of the current generator frame is typically a hollow tube structure, and the legs are mounted on the hollow tubes of the frame. Since the legs require drilling holes in the hollow tubes to install the legs, water easily enters the tubes after drilling, which easily causes rust inside the tubes, thereby affecting the service life and support stability of the hollow tubes. Since the two legs are installed on the first crossbeam in this embodiment, compared with conventional models that reduce the strength of the frame and cause rust, this embodiment can be installed without destroying the frame structure, ensuring the integrity of the frame structure. While maintaining the strength of the frame, it also avoids the disadvantages of reducing the strength of the frame and causing rust due to drilling holes to install the legs.

[0012] As a preferred embodiment of the present invention, the second support plate is provided with a plurality of lightening holes. By providing a plurality of lightening holes on the connecting plate, the weight of the connecting plate can be reduced, thereby reducing the total weight of the whole device, which is conducive to the lightweight design of the portable generator.

[0013] As a preferred embodiment of the present invention, the second bent portions on opposite sides of the first and second crossbeams are each provided with an embedding groove at a position corresponding to the connecting plate, and the ends of the connecting plate are inserted into the embedding groove for fixation. This solution, by inserting the ends of the connecting plate into the embedding groove for fixation, can increase the connection area between the connecting plate and the first and second crossbeams, thereby making the connection more stable. Moreover, the embedding fixation allows the connecting plate to be partially embedded in the first and second crossbeams, thereby enhancing the strength and stability of the overall structure.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0022] See also Figure 1 As shown, this embodiment discloses a generator set frame, including a frame 1 located outside the generator. Frame 1 adopts a hollow tube structure to reduce the weight of the entire machine. Two parallel first and second beams 2 and 3 are provided at the bottom of frame 1. The ends of the first and second beams 2 and 3 are welded to the sides of frame 1. The generator set is mounted on the first and second beams 2 and 3. Specifically, two parallel mounting plates 9 are provided above the first and second beams 2 and 3. The ends of the mounting plates 9 are respectively mounted on the first and second beams 2 and 3 via shock-absorbing supports 8. The generator is mounted on two mounting plates 6.

[0023] Two parallel connecting plates 6 are welded between the first crossbeam 2 and the second crossbeam 3. Figure 4 As shown, the connecting plate 6 includes a first support plate 61 and a second support plate 62 formed by bending the lower side of the first support plate 61. Several lightening holes 63 are evenly distributed along the length of the first support plate 61 to reduce the total weight of the whole machine. A reinforcing rib 64 is formed at the corner between the first and second support plates 61, 62. Two lugs 65 protrude upward from the upper side of the first support plate 61. The edges of the lugs 2 and the upper side of the first support plate 61 are both folded outward. To prevent the generator from falling during transportation, an anti-fall structure is also provided on the support structure. The two lugs 65 are connected to the anti-fall structure. Figure 2 and Figure 3 As shown, the first crossbeam 2 includes a straight portion 21, the two sides of which are bent downward to form a first bent portion 22. The lower sides of the two first bent portions 22 are bent outward to form a second bent portion 23. The structure of the second crossbeam 3 differs from that of the first crossbeam 2 in that the second bent portion 23 on the side of the second crossbeam 2 away from the connecting plate 6 is folded upward to form a hem 31. By folding the hem 31, the load-bearing strength of the second crossbeam 2 is increased, and the material wall thickness can be reduced while maintaining the same load-bearing strength, which is beneficial for reducing costs. The second bent portions 23 on the opposite sides of the first crossbeam 2 and the second crossbeam 3 are respectively provided with an inserting groove 4 at the position corresponding to the connecting plate 6. The two ends of the connecting plate 6 are respectively inserted into the corresponding inserting groove 4 and then welded to secure. In this embodiment, by setting two connecting plates 6 between the first beam 2 and the second beam 3, the first beam 2 and the second beam 3 supporting the generator can be connected to form a whole, so as to evenly distribute the load on the first beam 2 and the second beam 3, thereby enhancing the overall load-bearing strength of the beam structure and solving the current problems of insufficient load-bearing strength and uneven force of the beams.

[0024] Furthermore, two rollers 7 are mounted on the bottom of the frame 1 to facilitate movement of the generator. The first crossbeam 2 is located away from the rollers 7. Two legs 5 are detachably attached to the underside of the first crossbeam 2. These legs 5 and the two rollers 7 support the ground, keeping the generator upright. In this embodiment, since the legs 5 are mounted on the first crossbeam 2, the structural integrity of the frame 1 is maintained without disrupting it. This avoids the disadvantages of conventional models that reduce frame strength and cause rust by inserting holes in the frame tubes to install leg supports.

[0025] Furthermore, reinforcement plates 10 are welded to either side of the bottom of the frame 1. These plates extend toward both ends of the frame 1, near the center of gravity of the engine block. In this embodiment, by providing reinforcement plates 10 on either side of the bottom of the frame 1, the localized area at the bottom of the frame 1, where forces are more concentrated, can be further reinforced, thereby further improving the overall structural strength of the frame 1 and ensuring structural stability.

[0026] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
