Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 - 5 The utility model provides a rotary RV stepping mechanism, comprising:

[0027] A rotating frame 1, which is horizontally rotatably connected to the vehicle body, and an electric step assembly 3 is arranged on the rotating frame 1;

[0028] The locking mechanism includes a lock pin arranged on the rotating frame 1 and a latch 11 arranged on the vehicle body. The latch 11 and the lock pin are arranged correspondingly. A lock link mechanism 10 is also arranged on the vehicle body. The lock link mechanism 10 is transmission-connected with the latch 11.

[0029] The telescopic legs 12 are arranged on the rotating frame 1 .

[0030] The main function of the rotating frame 1 is to drive the electric step assembly 3 to rotate relative to the vehicle body, so as to change the position of the electric step, and realize two usage modes of entering the vehicle through the step or entering the expansion platform through the step; the main function of the latch 11 is to lock the lock pin when the rotating frame 1 is put into the vehicle, so as to prevent the rotating frame 1 from rotating accidentally; the main function of the locking link mechanism 10 is to unlock the latch 11 from the lock pin when the rotating frame 1 needs to be rotated out; the main function of the telescopic legs 12 is to provide auxiliary support to the rotating frame 1 after the rotating frame 1 is rotated out of the vehicle body, so as to improve the stability of the rotating frame 1. On the whole, the rotating RV step mechanism of the utility model has a delicate and reliable structure, is convenient and practical, has multiple uses, and effectively reduces the cost. Not only can the electric step be turned on to allow passengers to get on and off the vehicle normally from the door, but also when the RV is equipped with the expansion platform, the step of the scheme can be rotated counterclockwise or clockwise to a suitable position, and then the RV can enter the expansion platform to rest or enter the vehicle through the step.

[0031] According to a further optimized solution, a rotating shaft 2 is vertically fixedly connected to one side wall of the rotating frame 1 , and the rotating frame 1 is rotatably connected to the vehicle body via the rotating shaft 2 .

[0032] The rotating frame 1 forms a rotational connection with the vehicle body through the rotating shaft 2, which not only connects the rotating frame 1 and the electric step assembly 3 to the vehicle body to avoid disassembly and transportation, but also realizes the displacement of the electric step assembly 3 by rotating the rotating frame 1, which is suitable for use after building an expansion platform.

[0033] Further optimization scheme, such as Figure 3 As shown, the lock linkage mechanism 10 includes a buckle 14 fixedly connected to the vehicle body, the movable end of the buckle 14 is hinged to one end of a first pull rod 15, the other end of the first pull rod 15 is hinged to one end of a first rotating axis bracket 16, the middle part of the first rotating axis bracket 16 is hinged to the vehicle body, the end of the first rotating axis bracket 16 away from the first pull rod 15 is hinged to one end of a second pull rod 17, the other end of the second pull rod 17 is hinged to one end of a second rotating axis bracket 18, the middle part of the second rotating axis bracket 18 is hinged to the vehicle body, the end of the second rotating axis bracket 18 away from the second pull rod 17 is hinged to one end of a third pull rod 19, and the other end of the third pull rod 19 is hinged to the latch 11.

[0034] like Figure 3As shown, the handle 14 has a conventional structure, and its mechanism and working principle will not be elaborated further. When the operator pulls the handle 14, the handle 14 will pull the first pull rod 15, rotate the first rotating shaft bracket 16 by a certain angle through the first pull rod 15, and pull the second pull rod 17 through the first rotating shaft bracket 16, so that the second pull rod 17 pulls the second rotating shaft bracket 18 to rotate by a certain angle, and finally pulls the third pull rod 19, pulls the catch 11 to rotate and move by an angle around its rotating shaft through the third pull rod 19, releases the lock pin, and after opening the second locking mechanism, the rotating frame 1 can be rotated and opened.

[0035] In a further optimized solution, a second locking mechanism is also provided on the rotating frame 1. The second locking mechanism includes a bolt 4, a first slot 5 fixedly connected to the side wall of the rotating frame 1, and a second slot 13 fixedly connected to the vehicle body. A first through hole and a second through hole are respectively formed on the first slot 5 and the second slot 13, and the bolt 4 is correspondingly arranged with the first through hole and the second through hole.

[0036] To improve the position stability of the rotating frame 1 after it rotates into the vehicle, after the lock pin of the locking column of the catch 11 is locked, the first through hole and the second through hole on the first slot 5 and the second slot 13 are in an aligned state. At this time, the user can insert the bolt 4 from top to bottom into the second through hole and the first through hole, so that a connection is formed between the first slot 5 and the second slot 13, and the rotating frame 1 is limited.

[0037] In a further optimized solution, a first support plate 8 is also fixedly connected to the rotating frame 1. The first support plate 8 is arranged away from the rotating shaft 2, and a universal ball support 7 is arranged on the first support plate 8. A second support plate is fixedly connected to the vehicle body, and the universal ball support 7 is correspondingly arranged with the second support plate.

[0038] In a further optimized solution, a guide plate 6 is also arranged below the first support plate 8, and the guide plate 6 is fixedly connected to the rotating frame 1.

[0039] When the rotating frame 1 drives the electric step assembly 3 to rotate back from the rotating position to the inside of the vehicle, that is, when it rotates back to the normal position, under the guiding action of the guide plate 6, the universal ball support 7 contacts the top surface of the second support plate, automatically supporting the rotating frame 1 to the normal position and preventing it from sagging.

[0040] In a further optimized solution, the telescopic support leg 12 is fixedly connected to the side wall of the rotating frame 1 away from the rotating shaft 2.

[0041] The telescopic support leg 12 can be an electric adjustable telescopic support leg or a manual adjustable support leg. Since the telescopic support leg 12 has a common structure, its working principle and working process will not be elaborated further.

[0042] When the rotating frame 1 rotates to the rotating position, since the rotating frame 1 is only supported by the rotating shaft 2 on one side, in order to prevent the rotating frame 1 from deforming under force, the telescopic support leg 12 can be extended to support the side of the rotating frame 1 away from the rotating shaft 2, reduce the load of the rotating frame 1, and improve the use stability and durability.

[0043] A motorhome includes a vehicle body. The above-mentioned rotary motorhome step mechanism is arranged on the side of the vehicle body, and the rotary motorhome step mechanism is correspondingly arranged with the motorhome door and the expansion platform.

[0044] The working process of this embodiment is as follows: In the case of not building the expansion platform, the rotating frame 1 is inside the vehicle body, the catch 11 and the locking pin are in the locked state, and the insertion pin 4 connects the first slot 5 and the second slot. The user can directly enter and exit the vehicle through the door by unfolding the electric step assembly 3. When it is necessary to build and use the expansion platform, the user can pull out the insertion pin 4, then press the lock switch 9 to unlock the catch 11 and the locking pin. After that, rotate the rotating frame 1 out around the rotating shaft to the edge of the expansion platform, then control the telescopic support leg 12 to extend and contact the ground, and then open the electric step assembly 3, and then the user can enter the expansion platform or enter and exit the vehicle through the electric step assembly 3.
