Description

Technical Field

[0001] This utility model relates to the field of RV interior structure, specifically a retractable platform structure for RV interior. Background Technology

[0002] A motorhome (RV) is a special vehicle that combines transportation and living functions, equipped with sleeping, kitchen, bathroom, and other living facilities, suitable for travel, camping, and other scenarios. Based on driving force, they are divided into self-propelled and towed types. The body often uses a sandwich composite structure, and the interior is divided into functional areas such as driving, living, and bedroom. Most existing motorhomes have either fixed "table structures" (including internal tables) or detachable installations. The first type of "table structure" takes up space; the second type is cumbersome to install and remove, wasting time. Therefore, to solve these problems, the "table structure" inside motorhomes has been designed and improved. Utility Model Content

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] Example 1 like Figures 1 to 4 As shown, a retractable table structure for a motorhome interior is disclosed. This table structure is retractable and movably installed inside the motorhome (and can be used as a table structure inside the motorhome). The table structure includes a table panel 1 for installation in a table mounting groove on the floor inside the motorhome. Sliding guide plates 11 are connected to both sides of the bottom end of the table panel 1. A sliding groove is opened at one end of each sliding guide plate, and a sliding shaft is slidably adapted in each sliding groove. A scissor-type lifting frame 2 is provided at the end of each sliding shaft away from the sliding guide plate 11 for driving the table panel 11 to rise and fall. The end of each sliding shaft away from the sliding guide plate 11 is connected to one side of the top of the scissor-type lifting frame 2. The other side of the top of the scissor-type lifting frame 2 is hinged to the end of the sliding guide plate 11 away from the sliding shaft via a pin. Two hinge points in the middle of the two scissor-type lifting frames 2 are connected by connecting shafts 21, and movable lead screws 3 are connected to the two connecting shafts 21 for driving the two connecting shafts 21 to move relative to each other.

[0014] In this embodiment, the platform structure is installed in a platform mounting slot on the floor inside the RV (the mounting slot is designed inside the RV for installing the platform structure). When the platform structure is needed (used as a table structure), the movable screw 3 is controlled to rotate, causing the two connecting shafts 21 to move closer together, thereby simultaneously raising the two scissor lifts 2 and raising the platform 1 to a certain height for use as a table. When not needed, the movable screw 3 is controlled to rotate (in the opposite direction to the movement of the two connecting shafts 21 closer together), causing the two connecting shafts 21 to move away, thereby simultaneously lowering the two scissor lifts 2 and returning the platform 1 to the platform mounting slot. A protective cover is also placed on the top of the platform mounting slot to protect the platform 1. This makes the entire platform structure easy to control and saves time; furthermore, it reduces the space occupied inside the RV when not in use.

[0015] It should be noted that the scissor lift frame 2 is an existing scissor lift structure frame, so its specific structure is not further described in this embodiment.

[0016] Example 2 Based on Embodiment 1, the bottom ends of the two scissor lift frames 2 are provided with a fixed base plate 4 (that is, a fixed base plate is provided below the moving platform panel 1); the fixed base plate 4 is used to connect with the bottom end of the platform mounting groove of the RV interior floor; the bottom ends of the two scissor lift frames 2 are used to install and connect with the fixed base plate 4.

[0017] The top two sides of the fixed base plate 4 are respectively connected to connecting plates 41; the side walls of the connecting plates 41 are provided with movable grooves, which are located below and on the same side as the sliding groove. Movable shafts are slidably adapted in the movable grooves, and the ends of the movable shafts away from the connecting plates 41 are respectively used to connect to one side of the bottom end of the scissor lift frame 2; the other side of the bottom end of the scissor lift frame 2 is respectively used to be hinged to the end of the connecting plate 41 away from the movable groove through pins.

[0018] Furthermore, one end of the movable lead screw 3 is threaded and rotatably passes through two connecting shafts 21 with opposite thread directions; the movable lead screw 3 drives the two connecting shafts 21 to move relative to each other (moving closer or further apart). Simultaneously, the other end of the movable lead screw 3 is connected to the output shaft of a stepper motor 5 via a shaft connector. The stepper motor 5 is connected to the lifting mechanism via a motor mounting bracket. The lifting mechanism includes an electric movable guide rail 6; the motor mounting bracket is used for lifting and lowering the electric movable guide rail 6, and the electric movable guide rail 6 is bolted to the interior of the RV and the inner wall of the platform mounting slot.

[0019] In this embodiment, by controlling the stepper motor 5 to start (the controller inside the RV controls the start and stop of the stepper motor 5), the stepper motor 5 drives the movable lead screw 3 to rotate. When the stepper motor 5 drives the movable lead screw 3 to rotate "forward", since the two connecting shafts 21 have "opposite thread direction" to the movable lead screw 3, the two connecting shafts 21 move closer to each other, thereby driving the two scissor lift frames 2 to rise synchronously, and thus driving the platform 1 to rise to a certain height for people to use. When it is not needed, by controlling the stepper motor 5 to drive the movable lead screw 3 to rotate "reverse", the two connecting shafts 21 move away from each other, thereby driving the two scissor lift frames 2 to descend synchronously, and thus driving the platform 1 back into the platform mounting groove on the floor inside the RV, and a protective cover is placed on the top end of the platform mounting groove.
