Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to a controller frame for a hybrid loader. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] A loader is a type of earthmoving machinery widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. It is mainly used for loading and unloading bulk materials such as soil, sand, gravel, lime, and coal, and can also perform light digging operations on ores and hard soil. By changing different auxiliary working devices, it can also perform bulldozing, lifting, and loading and unloading operations of other materials such as timber.

[0004] In recent years, energy conservation, emission reduction, and green environmental protection have gradually become the dominant concepts in global industrial development. Hybrid technology is recognized internationally as one of the best energy conservation and emission reduction solutions. Therefore, both domestic and foreign companies have begun to shift the power source of construction machinery to hybrid technology, among which hybrid loaders are one of the key development areas.

[0005] Currently, due to the use of hybrid motor technology in hybrid loaders, the requirements for their controllers are correspondingly more complex. The inventors discovered that existing controller frames mostly use a multi-layered plate support structure. This arrangement has the disadvantages of unreasonable multi-controller layout and is prone to interference problems. Moreover, using multi-layered support plates increases the weight of the frame itself, which not only increases the burden on the vehicle frame but also increases its manufacturing cost.

[0034] like Figure 1 As shown, this embodiment discloses a controller frame for a hybrid loader, including: four support columns and a bottom mounting frame, a middle mounting frame, and a top mounting frame welded to the support columns, wherein the four support columns, the bottom mounting frame, the middle mounting frame, and the top mounting frame form a frame structure. The distance between the bottom mounting frame and the middle mounting frame is smaller than the distance between the middle mounting frame and the top mounting frame, and the top mounting frame is welded to the top of the four support columns.

[0035] The top mounting bracket is used to install the motor radiator and high-voltage box controller, the middle mounting bracket is used to install the all-in-one controller, and the bottom mounting bracket is used to install the generator controller.

[0036] The four supporting columns specifically include support column 1, support column 2, support column 3, and support column 4, which are located at the four corners of the rectangular frame. All four supporting columns are rectangular square tubes.

[0037] The bottom mounting bracket is welded at a predetermined distance from the bottom of the support column, and includes a first crossbeam 5, a second crossbeam 6, a first longitudinal beam 8, and a second longitudinal beam 7, all on the same plane.

Multiple mounting seats are correspondingly arranged on the first crossbeam 5 and the second crossbeam 6 for fixing and installing the generator controller.

[0038] The first crossbeam 5, the second crossbeam 6, the first longitudinal beam 8, and the second longitudinal beam 7 are all rectangular tubes. In this embodiment, the first crossbeam 5 and the second crossbeam 6 are of equal length, the first longitudinal beam 8 and the second longitudinal beam 7 are of equal length, and the first crossbeam 5 is longer than the first longitudinal beam 8.

[0039] The middle-layer mounting frame is welded to support columns at a predetermined distance above the bottom-layer mounting frame. It includes a third crossbeam 9, a fourth crossbeam 10, a third longitudinal beam 12, a fourth longitudinal beam 13, and a first angle steel 11, all on the same plane.

[0040] The third horizontal beam 9, the fourth horizontal beam 10, the third longitudinal beam 12, and the fourth longitudinal beam 13 are all rectangular square tubes, and the first angle steel 11 is a triangular angle steel. In this embodiment, the third horizontal beam 9, the fourth horizontal beam 10, and the first angle steel 11 are of equal length and are equal in length to the first horizontal beam 5, and the third longitudinal beam 12 and the fourth longitudinal beam 13 are of equal length.

[0041] The top-level mounting frame is welded to the very top of the four supporting columns. Specifically, it is a rectangular frame structure welded together from the fifth horizontal beam 14, the sixth horizontal beam 15, the fifth longitudinal beam 16, the sixth longitudinal beam 17, and the second angle steel 21. The lengths of the fifth longitudinal beam 16 and the sixth longitudinal beam 17 are greater than the distance between the second supporting column 2 and the third supporting column 3. The two ends of the fifth horizontal beam 14 are welded to one end of the fifth longitudinal beam 16 and the sixth longitudinal beam 17, respectively. The other ends of the fifth longitudinal beam 16 and the sixth longitudinal beam 17 are connected by the second angle steel 21.

The distance between the sixth horizontal beam 15 and the fifth horizontal beam 14 is equal to the distance between the second supporting column 2 and the third supporting column 3.

[0042] A seventh longitudinal beam 18 is welded between the fifth crossbeam 14 and the sixth crossbeam 15, and works in conjunction with the sixth longitudinal beam 17 to install the motor radiator. Multiple mounting seats are arranged on the seventh longitudinal beam 18 and the sixth longitudinal beam 17 respectively.

[0043] A fourth angle steel 23 and a fifth angle steel 24 are welded between the fifth crossbeam 14 and the sixth crossbeam 15, which cooperate with the fifth longitudinal beam 16 to fix the high-voltage box controller. The fourth angle steel 23 and the fifth angle steel 24 are arranged alternately between the seventh longitudinal beam 18 and the fifth longitudinal beam 16, and the distance between the seventh longitudinal beam 18 and the sixth longitudinal beam 17 is much greater than the distance between the fourth angle steel 23 and the fifth angle steel 24.

[0044] Above the end of the fifth longitudinal beam 16 and the sixth longitudinal beam 17 where the second angle steel 21 is welded, the first column 19 and the second column 20 are respectively welded.

[0047] In this embodiment, auxiliary support legs 25 are also welded under the bottom mounting frame. There are two auxiliary support legs 25, which are welded to the bottom surfaces of the first longitudinal beam 8 and the second longitudinal beam 7 respectively. The distance between the auxiliary support leg 25 and the second support column 2 is smaller than the distance between the auxiliary support leg 25 and the third support column 3. This ensures that the controller frame is stable and does not interfere with other components.

[0048] The bottom of each of the four support columns and two auxiliary support legs 25 is welded with a frame mounting base 26, which has frame mounting holes. The frame mounting base 26 is specifically shaped like a bent plate, which increases the welding area with the support columns and auxiliary support legs 25, ensuring the overall frame's robustness and thus improving the stability of the controller frame.

[0049] In this embodiment, several sealing shell mounting holes are provided on the outer sides of the aforementioned crossbeams and longitudinal beams, allowing for the installation of cover plates to seal the controller frame. Several threaded seats are also provided on the crossbeams and longitudinal beams for organizing and securing the various controller wiring harnesses.

[0050] In this embodiment, when the controller frame is mounted on the vehicle frame, a shock absorber can be added under the frame mounting base 26 to provide a buffer for the controller and ensure its stability.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
