[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-3 The diagram shown is a structural schematic of an embodiment of the electric-assisted manual passenger staircase walking mode switching device of this utility model. Please refer to [link / reference]. Figures 1-3 This paper provides a detailed introduction to an electric-assisted manual passenger staircase travel mode switching device.

[0022] An electric-assisted manual passenger boarding stairs travel mode switching device includes a frame 100, electric drive wheels 200, fixed wheels 300, a hydraulic cylinder 400, a hydraulic pump 500, and a control switch. The frame 100 provides a supporting structure for the entire device. As a basic support component, the frame 100 ensures the stability of the installation positions of other components, enabling the entire switching device to operate normally and ensuring the structural integrity of the passenger boarding stairs in different modes. The electric drive wheels 200 are installed at the bottom of the frame 100, and the fixed wheels 300 are distributed at the bottom of the frame 100. One end of the hydraulic cylinder 400 is connected to the frame 100, and the other end is connected to the electric drive wheels 200. The hydraulic pump 500 is connected to the hydraulic cylinder 400 through hydraulic lines, and the control switch is electrically connected to the hydraulic pump 500. This allows for hydraulic control of the lifting and lowering of the electric drive wheels 200, thereby switching the travel mode, which is more convenient and efficient than traditional methods.

[0023] Among them, there are multiple fixed wheels 300, which can provide stable support for the passenger boarding stairs in different modes, ensuring the balance and safety of the passenger boarding stairs during movement.

[0024] The control switch is installed on the frame 100 in a convenient location, allowing the user to operate it quickly and switch between walking modes, thus improving ease of operation.

[0025] The hydraulic cylinder 400 is automatically controlled by the hydraulic pump 500, which realizes the automated control of the lifting of the electric drive wheel 200, saving manpower and improving the speed and accuracy of mode switching.

[0026] Wherein: the hydraulic pump 500 is connected to the hydraulic cylinder 400 through a hydraulic pipeline. The hydraulic pipeline ensures that the hydraulic oil can be stably transmitted between the hydraulic pump 500 and the hydraulic cylinder 400, ensuring the normal operation of the hydraulic cylinder 400 and realizing the smooth lifting and lowering of the electric drive wheel 200.

[0027] Wherein: the electric drive wheel 200 is used to provide power to the passenger boarding elevator in electric drive mode. The electric drive wheel 200 drives the passenger boarding elevator to move automatically in electric drive mode, realizing labor-saving movement of the passenger boarding elevator, improving work efficiency, and is suitable for different usage scenarios.

[0028] In practical use, when switching the passenger boarding bus to manual mode, the user presses the control switch. The control switch sends a signal to the hydraulic pump 500, which starts and retracts the hydraulic cylinder 400. At this time, the electric drive wheels 200 rise, and the passenger boarding bus is supported by multiple fixed wheels 300. The user can then push the passenger boarding bus manually. When switching back to electric drive mode, the control switch is operated again, causing the hydraulic pump 500 to work in reverse. The hydraulic cylinder 400 extends, the electric drive wheels 200 descend to contact the ground, and the fixed wheels 300 provide auxiliary support. The electric drive system is then activated, and the passenger boarding bus can move automatically under the drive of the electric drive wheels 200.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
