Therefore, it is particularly necessary to develop an electric step device that can be both electrically driven and manually operated. Utility Model Content
[0004] Purpose of the utility model: The purpose of this utility model is to provide a solution to the problem that when the power is cut off or the motor fails, the traditional electric steps in RVs cannot be retracted or deployed by other means, which may prevent users from entering or exiting the RV normally in emergency situations, causing inconvenience and safety hazards.
[0005] Technical solution: An electric step device with manual retraction and deployment functions, including a mounting frame, wherein movable plates 1 are provided on the front and rear surfaces of the mounting frame, movable plates 2 are provided on opposite sides of the two movable plates 1, and pedal 1 is provided on the front of the opposite sides of the two movable plates 2, movable plates 3 are provided on the front and rear surfaces of the mounting frame and on the right side of the two movable plates 1, movable plates 4 are provided on opposite sides of the two movable plates 3, and pedal 2 is provided on the front of the opposite sides of the two movable plates 4;
[0006] An operating handle is provided on the front surface of the movable plate located in front of the mounting frame.
[0007] Furthermore, the upper surface of the mounting frame begins to have multiple through mounting holes.
[0008] Furthermore, connecting rods are provided on the opposite sides of the two movable plates one and the opposite sides of the two movable plates three.
[0009] Furthermore, it also includes two support rods. The opposite sides of the two movable plates three are movably connected to the top of the two movable plates four. The top of the opposite sides of the two support rods are movably connected to the opposite sides of the two movable plates two. The bottom of the opposite sides of the two support rods are movably connected to the opposite sides of the two movable plates four.
[0010] Furthermore, both the upper surfaces of pedal one and pedal two are integrally formed with anti-slip textures.
[0011] Beneficial effects: When the electric stepper is powered off, the user can directly enter manual operation mode by rotating the operating handle. The operating handle unlocks the manual drive mechanism, allowing for independent operation without interference from the motor drive system. After rotating the operating handle to the unlocked state, the user pulls the front end of the stepper. Step 1 and Step 2 unfold step by step through the cooperation of movable plates 1, 2, 3, and 4, support rods, and hinges until fully unfolded. Once the stepper reaches its unfolded end, the user needs to return the operating handle to the locked state. At this point, the stepper is fixed in the unfolded position, ensuring safety and stability. When the user needs to fold the stepper, they rotate the operating handle to the unlocked state and then push the front end of the stepper back. The device folds back step by step through the hinge mechanism. Once the stepper is fully folded, the user returns the operating handle to the locked state, ensuring the device remains fixed in its initial position, preventing loosening or slippage, thereby increasing the safety and stability of the device.

[0014] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] Example 1
[0016] like Figure 1 As shown, the upper surface of the mounting frame 1 has multiple through mounting holes 9.
[0017] The mounting frame 1 serves as an important supporting structure for the electric step device. Multiple through-hole mounting holes 9 on its upper surface provide reliable mounting points for the connection between the device and the RV body. By using appropriate bolts, nuts, and other connectors through the mounting holes 9, the mounting frame 1 can be firmly fixed in the designated position of the RV, ensuring that the entire electric step device remains stable during vehicle operation and will not loosen or shift due to vibration, bumps, or other factors.
[0018] like Figure 1 As shown, an electric step device with manual retraction and deployment functions is provided, including a mounting frame 1. Movable plates 1 and 2 are provided on the front and rear surfaces of the mounting frame 1. Movable plates 2 and 3 are provided on opposite sides of the two movable plates 1 and 2. A pedal 4 is provided on the front and opposite sides of the two movable plates 2 and 3. Movable plates 3 and 5 are provided on the front and rear surfaces of the mounting frame 1 and on the right side of the two movable plates 1 and 2. Movable plates 4 and 6 are provided on opposite sides of the two movable plates 3 and 6. A pedal 2 and 7 are provided on the front surface of the movable plates 1 and 2 located in front of the mounting frame 1. An operating handle 8 is provided on the front surface of the movable plates 1 and 2 located in front of the mounting frame 1. A connecting rod 10 is provided on the opposite sides of the two movable plates 1 and 2 and the opposite sides of the two movable plates 3 and 5.
[0019] It also includes two support rods 11. The opposite sides of the two movable plates 3 5 are movably connected to the top of the two movable plates 4 6. The top of the opposite sides of the two support rods 11 are movably connected to the opposite sides of the two movable plates 2 3. The bottom of the opposite sides of the two support rods 11 are movably connected to the opposite sides of the two movable plates 4 6.
[0020] When the electric stepper is powered off, the user can directly enter the manual operation mode by rotating the operating handle 8. The function of the operating handle 8 is to unlock the manual drive mechanism and achieve independent operation without interference from the motor drive system. After rotating the operating handle 8 to the unlocked state, the user pulls the front end of the stepper. The pedal 1 4 and pedal 2 7 unfold step by step through the cooperation of the movable plate 1 2, movable plate 2 3, movable plate 3 5, movable plate 4 6, support rod 11, and hinge structure until fully unfolded.
