[0035] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0036] Please refer to Figures 1 - 5 , the present invention discloses a simulation device for an excavator, including:

[0037] A simulation component 100, including a first connecting arm 110, a second connecting arm 120 and a bucket 150 that are sequentially rotatably connected;

[0038] A box body 200, one end of the first connecting arm 110 away from the second connecting arm 120 is rotatably connected to the inner wall of the box body 200;

[0039] The simulation component 100 has a deployed state and a stored state. In the deployed state, the simulation component 100 extends out of the box body 200; in the stored state, the simulation component 100 is stored in the box body 200, and both the second connecting arm 120 and the bucket 150 are below the first connecting arm 110.

[0040] The simulation component 100 set in this application includes a first connecting arm 110, a second connecting arm 120 and a bucket 150, which is equivalent to the upper arm, lower arm and bucket 150 in the excavator, and can restore the action of the excavator one-to-one, thereby realizing effective testing of the excavator control program.

[0041] At the same time, the simulation component 100 in the present application can be directly stored in the box 200 for easy transportation, and the storage of the simulation component 100 can be achieved simply by rotating it itself without disassembling any components, thereby enhancing the convenience of storing the simulation device.

[0042] Specifically, the bucket 150 first flips inward to the inner side of the second connecting arm 120, and then the second connecting arm 120 flips inward to the inner side of the first connecting arm 110. Finally, the first connecting arm 110 rotates relative to the inner wall of the box 200, so that the entire simulation component 100 is flipped into the box 200, thereby realizing the storage of the simulation component 100.

[0043] Similarly, the simulation device is rotated out of the box body 200 by rotating the first connecting wall relative to the inner wall, and then the second connecting arm 120 and the bucket 150 are flipped outward in turn to realize the deployment of the entire simulation device.

[0044] Furthermore, a mounting bracket 500 is provided on the inner wall of the box body 200 , and the mounting bracket 500 is rotatably connected to the first connecting arm 110 .

[0045] Specifically, a mounting bracket 500 is provided on the inner wall of the box body 200 and is hinged to the first connecting arm 110 , thereby preventing the first connecting arm 110 from being directly hinged to the box body 200 , which would cause the box body 200 and the first connecting arm 110 to collide.

[0046] Furthermore, the box body 200 has a first side panel and a second side panel on opposite sides;

[0047] The mounting bracket 500 includes two mounting plates 520 and a connecting plate 510. The two mounting plates 520 are respectively connected to the first side plate and the second side plate. The two ends of the connecting plate 510 are respectively connected to the two mounting plates 520. An articulated seat 530 hinged to the first connecting arm 110 is provided on the connecting plate 510.

[0048] A mounting plate 520 is respectively provided on the inner wall of the first side panel and the second side panel, so that the connecting plate 510 is connected to the two mounting plates 520 at the same time, and finally the entire simulation component 100 is hinged to the hinge seat 530 on the mounting plate 520. The weight of the entire simulation component 100 is transferred to the first side panel and the second side panel through the hinge seat 530, so that the first side panel and the second side panel are subjected to force together, thereby avoiding damage to the side panel on one side due to excessive force.

[0049] Further, the mounting plate 520 includes a horizontal section 522 and a vertical section 521 which are fixedly connected to each other. The vertical section 521 is bolted to the inner wall of the first side plate or the second side plate, and the horizontal section 522 is bolted to the connecting plate 510.

[0050] Specifically, the horizontal section 522 and the vertical section 521 are provided such that the vertical section 521 fits against the inner wall of the first side plate or the second side plate and is fixed by bolts, increasing the contact area between the mounting plate 520 and the inner wall of the box body 200, thereby increasing the connection strength between the mounting plate 520 and the box body 200. Similarly, the horizontal section 522 fits against the surface of the connecting plate 510 and is bolted, increasing the contact area between the connecting plate 510 and the mounting plate 520, thereby increasing the connection strength between the mounting plate 520 and the connecting plate 510.

[0051] Further, the simulation assembly 100 further includes a third connecting arm 130 and a fourth connecting arm 140. One end of the third connecting arm 130 is hinged to the fourth connecting arm 140, the other end of the third connecting arm 130 is hinged to the bucket 150, and one end of the fourth connecting arm 140 away from the third connecting arm 130 is hinged to the second connecting arm 120;

[0052] A position sensor 160 is respectively provided on the first connecting arm 110, the second connecting arm 120 and the fourth connecting arm 140.

[0053] It further includes a control screen 300 and an antenna 400. A connecting seat 310 is provided on the control screen 300, and the connecting seat 310 is bolted to the mounting bracket 500; a connecting column 523 is provided on the mounting bracket 500, and the antenna 400 is detachably connected to the connecting column 523.

[0054] The position sensor 160 is used to detect the position information of the first connecting arm 110, the second connecting arm 120 and the fourth connecting arm 140, and transmit it to the control screen 300 through the antenna 400. The control screen 300 issues an instruction to make the simulation assembly 100 act according to the control program and in combination with the information collected by the position sensor 160.

[0055] Further, a extension tube 410 is connected to the lower end of the antenna 400, and internal threads are provided on the inner wall of the extension tube 410;

[0056] External threads are provided on the connecting column 523, and the external threads can be engaged with the internal threads.

[0057] Further, the box body 200 includes a bottom plate, a plurality of side plates and a cover plate. The cover plate is rotatably connected to the side plates to open or close the box body 200.

[0058] Furthermore, a handle is provided on each side of the box body 200.

[0059] With the handles on both sides, it is convenient for the staff to apply force to lift the simulation device.

[0060] It should be mentioned that the control panel 300 and the antenna 400 are both detachably connected to the mounting bracket 500. When storing, the control panel 300 and the antenna 400 can be removed and placed in the box body 200 so that the cover plate can be completely closed.

[0061] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0062] In addition, in the present invention, descriptions such as "first", "second", "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0063] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
