[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The following is combined with Figures 1 to 9 This describes an embodiment of the present application.

[0041] According to an embodiment of this application, a mini excavator is provided, as shown in Title 1, comprising: a body and a foot pedal assembly 3.

[0042] The machine body includes a structural component 1 and a cockpit floor 2. The structural component 1 is the frame, and the cockpit floor 2 is connected to the structural component 1 for the operator to step on during operation.

[0043] The foot pedal assembly 3 includes a pedal 31, which is connected to the structural member 1. The height of the pedal 31 is lower than that of the cockpit floor 2, and the position of the pedal 31 is between the cockpit floor 2 and the ground. The pedal 31 has a footrest 311 for the operator to step on.

[0044] Before entering the cab of the mini excavator, the operator can first raise their feet from the ground to the height of pedal 31 and place their feet on the footrest 311 on pedal 31, and then raise their entire body to the height of pedal 31.

[0045] Next, the operator raises their feet from the footrest 311 on the pedal 31 to the height of the cockpit floor 2, places their feet on the cockpit floor 2, and then raises their entire body to the height of the cockpit floor 2 to enter the cockpit.

[0046] In this way, the operator can use pedal 31 as a transfer point and step onto the cockpit floor 2 by raising the height twice, reducing the height of each lift and making it easier and more convenient for the operator to enter the cockpit.

[0047] As an optional embodiment, such as Figure 5 As shown, the foot pedal assembly 3 includes a pedal 31, a back panel 32, and a side panel 33.

[0048] The footrest 311 has a first edge portion 3111 and a second edge portion 3112, which are adjacent to each other. The bottom of the back panel 32 is connected to the first edge portion 3111 of the footrest 311, so that the back panel 32 extends upward relative to the footrest 311 to form a certain angle with the footrest 311, preferably 90°. The bottom of the side panel 33 is connected to the second edge portion 3112 of the footrest 311, so that the back panel 32 extends upward relative to the footrest 311 to form a certain angle with the footrest 311, preferably 90°. The back panel 32 is also connected to the side panel 33.

[0049] Thus, after the pedal 31 is connected to the structural component 1, the pedal 31, the back guard plate 32, and the side guard plate 33 form a semi-enclosed structure. When the operator's foot is on the footrest 311, the back guard plate 32 and the side guard plate 33 are located on the outside of the foot, protecting the feet and preventing the foot from slipping off the footrest 311 of the pedal 31.

[0050] Furthermore, when the operator's foot is on the footrest 311, the back panel 32 and side panels 33 also provide a certain degree of protection for the machine body, preventing the operator from kicking the machine body and also preventing dust and impurities on the pedal 31 from entering the machine body.

[0051] Among them, the pedal 31, the back panel 32 and the side panel 33 can be connected as one piece and can be integrally formed during manufacturing, for example, by aluminum casting process.

[0052] In optional embodiments, such as Figure 1 As shown, the fuselage also includes a cover 4, which is connected to and covers the structural member 1. The top edge of the cover 4 engages with the outer edge of the cockpit floor 2.

[0053] Based on this, such as Figure 4As shown, a first mounting notch 21 is provided on the cover 4, and the first mounting notch 21 is located at the top edge of the cover 4. A second mounting notch 41 is provided on the cockpit floor 2, and the second mounting notch 41 is located at the outer edge of the cockpit floor 2.

[0054] The first mounting notch 21 and the second mounting notch 41 are joined together to form a mounting notch. The first mounting notch 21 has adjacent first side 211 and second side 212, and the second mounting notch 41 has adjacent third side 411 and fourth side 412. The second side 212 and the fourth side 412 are joined in the vertical direction.

[0055] The pedal 31 is provided with a third edge portion 3113, which is disposed opposite to the first edge portion 3111. The third edge portion 3113 is connected to the first side 211, so that the pedal 31 covers and closes the bottom surface of the mounting notch. The pedal 31 and the cover 4 together form the appearance surface.

[0056] like Figure 1 and Figure 2 As shown, the edge of the back panel 32 away from the pedal 31 is connected to the third side 411, so that the back panel 32 covers and closes the back of the mounting notch, and the back panel 32 and the cockpit floor 2 together form the exterior surface.

[0057] like Figures 1 to 3 As shown, the edge of the side guard plate 33 away from the pedal 31 is connected to the second side 212, and the edge of the side guard plate 33 away from the back guard plate 32 is connected to the fourth side 412. Thus, the side guard plate 33 covers and seals the side with the mounting notch. The side guard plate 33, the cockpit floor 2, and the back guard plate 32 together form the exterior surface.

[0058] In this way, the pedal 31, side guard plate 33, back guard plate 32, cab floor 2, and decorative panel 35 together form the exterior surface, ensuring the integrity of the mini excavator's appearance while installing the pedal 31 assembly. Furthermore, it effectively prevents external dust and foreign objects from entering the machine and damaging internal pipelines.

[0059] In some embodiments, such as Figure 1 As shown, a recessed portion 42 is provided on the cover 4 to increase the strength of the cover 4.

[0060] In a further embodiment, such as Figure 1 and Figure 5As shown, a first flange 321 is provided on the edge of the back panel 32 away from the pedal 31. After the pedal 31 is connected to the structural component 1, the first flange 321 is exactly combined with the third side edge 411 on the cockpit floor 2, so that the outer surface of the first flange 321 is flush with the outer surface of the cockpit floor 2. The overall appearance is neater and more beautiful, and the sealing is better, preventing external dust and foreign objects from entering the machine body and causing damage to the internal pipelines.

[0061] In some embodiments, an overlap groove can be provided on the third side 411 and an overlap portion can be provided on the first flange 321. After the pedal 31 is connected to the structural member 1, the overlap portion on the first flange 321 is exactly placed in the overlap groove on the third side 411, making the overall appearance neater and more aesthetically pleasing, and providing better sealing to prevent external dust and foreign objects from entering the machine body and causing damage to the internal pipelines.

[0062] like Figure 1 and Figure 5 As shown, a second flange 331 is provided on the edge of the side guard plate 33 away from the pedal 31. After the pedal 31 is connected to the structural component 1, the second flange 331 is exactly engaged with the second side edge 212 on the cover 4, so that the outer surface of the second flange 331 is flush with the outer surface of the cover 4, making the overall appearance neater and more beautiful and with better sealing, preventing external dust and foreign objects from entering the machine body and causing damage to the internal pipelines.

[0063] In some embodiments, an overlap groove can be provided on the second side 212, and an overlap portion can be provided on the second flange 331. After the pedal 31 is connected to the structural member 1, the overlap portion on the second flange 331 is exactly placed in the overlap groove on the second side 212, making the whole more neat and beautiful, and having better sealing performance, preventing external dust and foreign objects from entering the machine body and causing damage to the internal pipelines.

[0064] like Figure 1 and Figure 5 As shown, a third flange 332 is provided on the edge of the side guard plate 33 away from the back guard plate 32. After the pedal 31 is connected to the structural component 1, the third flange 332 is exactly combined with the fourth side edge 412 on the cockpit floor 2, so that the outer surface of the third flange 332 is flush with the outer surface of the cockpit floor 2. The overall appearance is neater and more beautiful, and the sealing is better, preventing external dust and foreign objects from entering the machine body and causing damage to the internal pipelines.

[0065] In some embodiments, an overlap groove can be provided on the fourth side 412 and an overlap portion can be provided on the third flange 332. After the pedal 31 is connected to the structural member 1, the overlap portion on the third flange 332 is exactly placed in the overlap groove on the fourth side 412, making the overall appearance neater and more aesthetically pleasing, and providing better sealing to prevent external dust and foreign objects from entering the machine body and causing damage to the internal pipelines.

[0066] It is worth noting that for the settings of the first flange 321, the second flange 331 and the third flange 332, you can set only one of them, or only any two of them, or you can set all three.

[0067] As an optional embodiment, such as Figures 5 to 7 As shown, the foot pedal assembly 3 includes not only the pedal 31, but also anti-slip ridges 34 and decorative panels 35.

[0068] The anti-slip protrusion 34 is provided on the pedal 31 and protrudes from the footrest 311. In this way, when the foot steps on the footrest 311, the anti-slip protrusion 34 contacts the sole of the foot, thereby increasing the friction between the foot and the pedal 31.

[0069] It is worth noting that the extension direction of the anti-slip ridge 34 should be perpendicular to the direction of entering the cockpit, so that when the driver steps on the pedal 31, the ball of the foot is perpendicular to the anti-slip ridge 34, thus ensuring that the anti-slip ridge 34 can play an anti-slip role.

[0070] A perforation 351 is provided through the decorative panel 35. After the decorative panel 35 is attached to the footrest 311, the anti-slip ridge 34 passes through the perforation 351 in the decorative panel 35. In this way, the decorative panel 35 can serve a decorative purpose, such as by using a special color or shape to increase its recognizability.

[0071] The perforation 351 prevents the anti-slip protrusion 34 from interfering with the installation of the decorative panel 35. Moreover, since the anti-slip protrusion 34 passes through the perforation 351, the anti-slip protrusion also provides some reinforcement to the decorative panel 35.

[0072] In a further embodiment, such as Figure 6 As shown, a mounting groove 3114 is provided on the footrest surface 311 of the pedal 31. An anti-slip protrusion 34 is connected to the bottom of the mounting groove 3114 and extends out of the groove. When installing the decorative panel 35, the decorative panel 35 is embedded in the mounting groove 3114. At this time, the anti-slip protrusion 34 passes through the perforation 351 on the decorative panel 35, and the side of the decorative panel 35 facing away from the bottom of the mounting groove 3114 is flush with the footrest surface 311. This keeps the footrest surface 311 flat.

[0073] The decorative panel 35 can be bonded to the bottom of the mounting groove 3114 with glue, or it can be fixed by other methods.

[0074] As an optional embodiment, such as Figure 9As shown, multiple reinforcing ribs 312 are provided on the side of the pedal 31 facing away from the footrest 311, and the reinforcing ribs 312 are distributed in a grid pattern by crossing each other in pairs. Each reinforcing rib 312 increases the strength of the pedal 31, making the pedal 31 have a better load-bearing capacity.

[0075] The height of the reinforcing rib 312 can be 7 mm.

[0076] In a further embodiment, such as Figure 8 and Figure 9 As shown, a stud 313 is provided on the side of the pedal 31 facing away from the footrest 311, wherein the stud 313 extends in the direction away from the pedal 31.

[0077] A mounting hole is made on the structural component 1. When connecting the pedal 31 to the structural component 1, the stud 313 is passed through the mounting hole on the structural component 1, and then the nut is put on and tightened to fix the pedal 31 to the structural component 1, making the installation more convenient.

[0078] In a further embodiment, such as Figure 9 As shown, a structural post 314 is provided on the side of the pedal 31 facing away from the footrest surface 311. The structural post 314 is located on the extension path of the reinforcing rib 312, thus connecting the structural post 314 to the reinforcing rib 312. One end of the stud 313 is embedded in the structural post 314, and the other end extends in the direction away from the pedal 31. That is, when manufacturing the pedal assembly 3, the stud 313 is pre-set so that after the pedal assembly 3 is integrally formed, the structural post 314 covers one end of the stud 313, realizing that the stud 313 is pre-embedded in the structural post 314.

[0079] Because the structural column 314 is connected to the reinforcing rib 312, the connection strength of the stud 313 is further increased.

[0080] As an optional embodiment, for the anti-slip protrusion 34, such as Figure 8 As shown, the width gradually decreases in the direction protruding from the footrest 311, that is, the cross section of the anti-slip protrusion 34 is trapezoidal, and the anti-slip protrusion 34 is a draft structure with both sides inclined inward.

[0081] The angle R between the sides of the anti-slip ridge 34 and the footrest 311 can be 87°, 88°, or any angle between 87° and 88°.

[0082] With this design, the anti-slip ridge 34 has a better anti-slip effect and a more aesthetically pleasing appearance.

[0083] In a preferred embodiment, the angle R between the two sides of the anti-slip protrusion 34 and the foot tread 311 can be 87.5°, that is, the draft angle of the anti-slip protrusion 34 is 2.5°.

[0084] As an optional embodiment, the mini excavator is an electric mini excavator, which is a mini excavator that uses electricity as its energy source. Because it needs to be equipped with a battery, its structure is more compact and the space utilization of each component is required to be higher.

[0085] Based on this, a first mounting notch 21 is provided on the cover 4, and a second mounting notch 41 is provided on the cab floor 2. The first mounting notch 21 and the second mounting notch 41 are combined to form a mounting slot, in which the foot pedal assembly can be placed without occupying additional space, which is more conducive to the overall layout of the electric mini excavator.

[0086] Moreover, electric mini excavators are more environmentally friendly and produce less noise.

[0087] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by this application.
