[0035] Please refer to Figures 2 to 6 in combination. Figure 2 is a schematic diagram of the structure of the combined pedal device provided in some embodiments of the present application in the expanded state. Figure 3 is a schematic diagram of the structure of the combined pedal device provided in some embodiments of the present application in the retracted state.

Figure 5 is a partial enlarged schematic diagram of the combined pedal device of Figure 4 at area A. Figure 6 1 is a schematic diagram of a combined pedal device provided in some embodiments of the present application. The combined pedal device 100 provided in the present application is equipped with an independent energy supply device 140, and does not need to draw power from the battery in the original vehicle. Therefore, the circuit modification of the original vehicle can be avoided, and it is convenient for installation, function expansion and maintenance. The combined pedal device 100 may include but is not limited to a fixed pedal 110, a movable pedal 120, a driving device 130, an energy supply device 140 and a controller 150. The fixed pedal 110 has a accommodating cavity 111 and a first pedal surface 112. The first pedal surface 112 is formed on one side of the accommodating cavity 111. The movable pedal 120 has a second pedal surface 121. At least part of the structure of the driving device 130 is arranged in the accommodating cavity 111. The driving device 130 is drivingly connected to the movable pedal 120 to drive the movable pedal 120 to be extended and retracted relative to the fixed pedal 110. When the movable pedal 120 is in the displayed state, the second pedal surface 121 and the first pedal surface 112 form a step structure to assist the driver and passengers to enter and exit the vehicle cabin conveniently. When the movable pedal 120 is in the retracted state, the second pedal surface 121 is hidden in the accommodating chamber 111. The energy supply device 140 is arranged in the accommodating chamber 111. On the one hand, it can obtain the protection of the fixed pedal 110. On the other hand, when the combined pedal device 100 is installed on the vehicle 1000, it can keep a sufficiently large distance from the ground, so as to ensure that the vehicle 1000 can travel in the wading area and facilitate the user to take and put the energy supply device 140. The energy supply device 140 is used to provide energy to the drive device 130. The controller 150 is arranged in the accommodating chamber 111, which can obtain the protection of the fixed pedal 110. The controller 150 is electrically connected to the energy supply device 140 and the drive device 130 respectively, so as to control the drive device 130 to drive the movable pedal 120 under the energy provided by the energy supply device 140.

[0036] Furthermore, when the movable pedal 120 is in the retracted state, the energy supply device 140 and the controller 150 are both opposite to the second pedal surface 121 to optimize the internal space in the fixed pedal 110 .

[0037] Further, when the movable pedal 120 is in the retracted state, the distance between any one of the energy supply device 140 and the controller 150 and the second pedal surface 121 is less than or equal to 5 mm, and can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc. In this way, the internal space of the fixed pedal 110 can be made more compact. In this embodiment, when the movable pedal 120 is in the retracted state, the distance between any one of the energy supply device 140 and the controller 150 and the second pedal surface 121 is equal to 2 mm.

[0038] Furthermore, when the movable pedal 120 is switched between the extended state and the retracted state, the second pedal surface 121 always remains parallel to the first pedal surface 112 .

[0039] Furthermore, the movable pedal 120 can hover at any position between the displayed state and the retracted state to adapt to different usage scenarios and different user groups.

[0040] In some other embodiments, the combined pedal device 100 further includes a water level detection device 160. The water level detection device 160 is disposed at the end of the fixed pedal 110. The water level detection device 160 is used to detect the height of the water level to prevent the vehicle 1000 from driving into a deep water area by mistake, thereby causing damage to the energy supply device 140 and the controller 150 in the combined pedal device 100.

[0045] Further, the mounting seat 131 may include but is not limited to a first position-limiting sub-mounting seat 1311 and a second position-limiting sub-mounting seat 1312.
