[0031] like Figures 1 to 4As shown, this utility model embodiment provides a foot pedal device, including a fixed pedal frame 11, a fixed pedal 12, a flip pedal frame 21, a flip pedal 22, a connector 40, and a locking assembly. The fixed pedal 12 is disposed on the fixed pedal frame 11; the flip pedal 22 is disposed on the flip pedal frame 21. One of the fixed pedal frame 11 and the flip pedal frame 21 has a round hole, and the other has a strip hole 2111. The connector 40 connects the fixed pedal frame 11 and the flip pedal frame 21 through the round hole and the strip hole 2111. The flip pedal frame 21 can rotate around the connector 40 and can... The rotating pedal frame 21 can slide along the strip hole 2111 and has an unfolded state and a folded state. The locking assembly includes a locking plate 31 and a pin 32. The locking plate 31 is disposed on the fixed pedal frame 11. The locking plate 31 has a first sliding groove 311. The extension direction of the first sliding groove 311 is consistent with the extension direction of the strip hole 2111. The groove wall of the first sliding groove 311 has a first locking groove 312. The pin 32 is disposed on the rotating pedal frame 21. When the rotating pedal frame 21 switches from the unfolded state to the folded state, the pin 32 can slide along the first sliding groove 311 and can be locked into the first locking groove 312.

[0032] When the foot pedal device is needed, the flip-up pedal frame 21 is in the unfolded state. At this time, the flip-up pedal 22 and the fixed pedal 12 are spaced apart along the height direction for the operator to use when getting on and off the vehicle. (Refer to...) Figure 3 When the foot pedal device is not needed, the flip pedal frame 21 is flipped over. The flip pedal frame 21 rotates around the connector 40, switching from an unfolded state to a folded state. At this time, the pin 32 enters the first sliding groove 311, and then slides along the first sliding groove 311. Simultaneously, the flip pedal frame 21 slides along the strip hole 2111 until the pin 32 engages with the first locking groove 312, thereby locking the flip pedal frame 21 in the folded state to save space and protect the pedal device. (Refer to...) Figure 1 and Figure 2 The flip-up pedal holder 21 can be unlocked by reversing the operation. The locking assembly involved in this embodiment has a simple structure, low cost, and is not prone to jamming or failure.

[0033] Reference Figure 1 and Figure 3 In this embodiment, both the strip-shaped hole 2111 and the first sliding groove 311 are inclined relative to the vertical direction. This arrangement allows for a reverse locking force on the pin 32 after it is engaged in the first slot 312, making the pin 32 more securely locked and less likely to come out of the first slot 312. Of course, in other embodiments, the strip-shaped hole 2111 and the first sliding groove 311 can also be distributed vertically, and are not limited to this embodiment.

[0034] Reference Figure 4In this embodiment, there are multiple first slots 312, and these multiple first slots 312 are spaced apart along the extending direction of the first sliding groove 311. The pin 32 can be engaged into one of the multiple first slots 312. By providing multiple first slots 312, it is sufficient for the pin 32 to be engaged into only one of the first slots 312, thereby increasing the locking probability of the pin 32. For example, the number of first slots 312 can be two, three, or more than three. Of course, in other embodiments, the number of first slots 312 can also be one.

[0035] Continue to refer to Figure 4 In this embodiment, the card plate 31 is also provided with a first clearance groove 313, which connects the edge of the card plate 31 and the first sliding groove 311. The pin 32 enters the first sliding groove 311 through the first clearance groove 313. By providing the first clearance groove 313, the arrangement of the card plate 31 on the fixed pedal frame 11 can be facilitated. Of course, in other embodiments, the card plate 31 may not have a clearance groove, and the pin 32 can directly enter the first sliding groove 311.

[0036] In this embodiment, the fixed pedal frame 11 is provided with a second sliding groove and a second clearance groove connecting the edge of the fixed pedal frame 11 and the second sliding groove. The groove wall of the second clearance groove is provided with a second locking groove. The second sliding groove has the same shape as the first sliding groove 311 and is directly opposite to it. The second clearance groove has the same shape as the first clearance groove 313 and is directly opposite to it. The second locking groove has the same shape as the first locking groove 312 and is directly opposite to it. The pin 32 passes through the first clearance groove 313 and the second clearance groove and then enters the first sliding groove 311 and the second sliding groove. The pin 32 slides in the first sliding groove 311 and the second sliding groove until it is locked into the first locking groove 312 and the second locking groove. With the above arrangement, it is easier to arrange the locking plate 31 on the fixed pedal frame 11 and it can ensure that the locking plate 31 coincides with the fixed pedal frame 11, thereby improving the strength of the locking plate 31.

[0037] Reference Figure 1 and Figure 3 In this embodiment, there are two locking plates 31 and two pins 32. The two locking plates 31 are located on opposite sides of the fixed pedal frame 11, and the two pins 32 are located on opposite sides of the flip pedal frame 21. Each pin 32 corresponds to one locking plate 31. This arrangement improves the stability of the locking assembly after locking. In this embodiment, the locking plate 31 is connected to the outer side of the fixed pedal frame 11.

[0038] Continue to refer to Figure 1 and Figure 3Furthermore, the pedal device provided in this embodiment also includes a handle 23, which is disposed on the flip pedal frame 21 or the flip pedal 22. When switching the flip pedal frame 21 between the unfolded state and the folded state, the handle 23 can be held to flip the flip pedal frame 21, making it easier for the operator to operate.

[0039] Continue to refer to Figure 1 and Figure 3 Furthermore, the pedal device provided in this embodiment of the invention also includes two handrails 50, both of which are connected to the fixed pedal frame 11 and are located on both sides of the fixed pedal 12. When operators get on and off the vehicle via the pedal device, they can hold onto the handrails 50 to ensure their safety.

[0040] Continue to refer to Figure 1 and Figure 3 Furthermore, the fixed pedal 12 and / or the flip pedal 22 are provided with anti-slip teeth to further improve the safety of operators getting on and off the vehicle.

[0041] Continue to refer to Figure 1 and Figure 3 In this embodiment, the fixed pedal frame 11 includes two first side plates 111 and a back plate 112 connected between the two first side plates 111. There are multiple fixed pedals 12, wherein the fixed pedal 12 located at the top layer is connected between the two first side plates 111, and the remaining fixed pedals 12 are connected to the back plate 112. The two sides of the fixed pedal 12 connected to the back plate 112 are spaced apart from the opposite first side plates 111. The flip pedal frame 21 includes two second side plates 211, and the flip pedal 22 is connected between the two second side plates 211. The two second side plates 211 are respectively connected to the two first side plates 111 and are located between the first side plates 111 and the fixed pedals 12. When the flip pedal frame 21 is in the unfolded state, the flip pedal 22 is located below the bottom fixed pedal 12. When the flip pedal frame 21 is in the folded state, the flip pedal 22 is located between the top fixed pedal 12 and the adjacent fixed pedal 12. With the above settings, when the flip pedal frame 21 is in the folded state, the flip pedal 22 can be completely hidden between the fixed pedals 12, preventing the flip pedal 22 from protruding from the fixed pedals 12, thus saving space.

[0042] This utility model embodiment also provides an engineering machine, including a frame and the aforementioned foot pedal device, wherein the fixed pedal frame 11 in the foot pedal device is connected to the frame. By adopting the aforementioned foot pedal device, space can be saved, safety when crossing obstacles can be improved, and the cost of replacing or maintaining the foot pedal device can be reduced.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
