[0008] As a preferred embodiment, the gear box comprises a box body, a driving gear and a driven gear meshing with the driving gear, the driving gear is fixedly sleeved on the motor output shaft of the motor, and the driven gear is fixedly sleeved on the gear output shaft, so that the transmission ratio of the driving gear and the driven gear can be selected according to the needs, and the movement speed is more easily adapted.

[0009] As preferred: a limiting gap section is formed on the ground foot, a limiting block is fixed on the outer wall of the handrail framework, and the outer end of the limiting block extends into the limiting gap section, so that the folding angle of the handrail can be effectively limited, and the folding failure can be avoided.

[0010] As preferred: the motor is fixed to the box through bolts, and the box is fixed to the handrail framework through bolts.

[0011] As preferred: the ground foot is located at the rear of the handrail framework.

[0012] Compared with the prior art, the utility model has the advantages of: 1. the electric angle adjuster has strong impact resistance; 2. the whole vehicle safety test can be satisfied; 3. the structure is compact and small in size, and the platformization can be easily realized; 4. the motor is arranged on the outer side of the handrail, and the internal space of the handrail is expanded; 5. the motor is arranged on the outer side of the handrail, connected through a gear box, the motor is effectively protected, the breaking torque of the motor is increased, the generality of the mechanism is higher, and the arrangement space is larger; 6. the gear box is connected, and the movement speed is more easily adapted.

[0017] The utility model will be further described below in combination with the embodiments and the drawings.

[0018] As Figures 1 to 4 ​As shown, an electric handrail structure is composed of an handrail frame 7, two angle adjusters 5, two feet 1 and other components, wherein the handrail frame 7 and the angle adjuster 5 are both existing structures and are not described in detail here. The two feet 1 are respectively located on both sides of the handrail frame 7 and at the rear of the handrail frame 7. The angle adjusters 5 are installed between the two outer walls of the handrail frame 7 and the corresponding feet 1. The two ends of the angle adjuster 5 are respectively connected to the handrail frame 7 and the feet 1. A gear box 4 is installed on the outside of one of the feet 1, and a motor 3 is installed on the outside of the gear box 4. The gear box 4 is driven by the motor 3; specifically: the gear box 4 includes a box body 41, The driving gear 42 and the driven gear 43 meshing with the driving gear 42 are located in the box body 41, wherein the driving gear 42 is fixedly mounted on the motor output shaft 2 of the motor 3, and the driven gear 43 is fixedly mounted on the gear output shaft 6.
