The components of the embodiments of the present utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0022] Specific embodiments of the integrated concealed sliding rail power supply device and electric lift bed for RVs provided by this utility model: Please see Figures 1-6 The RV integrated concealed sliding rail power supply device includes a sliding rail 1, a sliding base 2, a conductive sliding line 4, a side guard 3, a front guard 6, and a conductive brush 5.

[0023] The slide rail 1 has a U-shaped cross-section and is vertically arranged. Two slide rails 1 are arranged on one side of the lifting bed, and the two slide rails 1 are parallel. Each side of the slide rail 1 is provided with a vertical sliding support part 101, and the sliding support part 101 has a circular cross-section.

[0024] The slide seat 2 is connected to the lift bed of the RV and slides along the slide rail 1. Two sliders 7 are installed on the slide seat 2 near the slide rail 1 and slide along the sliding support part 101. The sliders 7 have a C-shaped cross section. The slide seat 2 near the slide rail 1 is provided with a bent part 8 to support the sliders 7. The sliders 7 and the bent part 8 are connected by bolts.

[0025] In this embodiment, one of the slide rails 1 and its corresponding slide block 2 are improved to form a concealed power transmission structure. Specifically, the conductive slide wire 4 is located on the front side of one of the slide rails 1 and has a U-shaped cross-section. Two conductive slide wires 4 are arranged parallel to each other on the front side of the slide rail 1. In some embodiments, one is a 12V positive output and the other is a 0V negative output.

[0026] Side blocks 3 are connected to the outside of slide rail 1 and shield both sides of conductive slide line 4. There are four side blocks 3 corresponding to two conductive slide lines 4, with a side block 3 on both sides of each conductive slide line 4. The side blocks 3 protrude more outward relative to the conductive slide line 4.

[0027] Conductive brushes 5 are mounted on the slide block 2 and extend into the inner side of the conductive slide line 4. There are two conductive brushes 5, each corresponding to one of the two conductive slide lines 4. The conductive brushes 5 are in contact with the conductive parts inside the conductive slide lines 4, and are connected to the electrical components on the lifting bed. The conductive slide lines 4 are connected to the power supply system to achieve electrical transmission. The lifting bed control system controls the power equipment on the lifting bed through electrical transmission.

[0028] The conductive slide wire 4 has L-shaped parts 401 connected to both sides. The L-shaped parts 401 are strip structures with an L-shaped cross section and are the insulation structure of the conductive slide wire 4 itself. The inner side of the side block 3 is provided with protruding strips 301 that support the inner side of the L-shaped parts 401.

The cross-section of the insertion part 601 is circular.

[0031] The front sides of the side guards 3 are connected to the front guard 6. When no conductive brush 5 passes through, the magnetic strips on the front sides of the two side guards 3 are attracted together, making the conductive sliding line 4 completely hidden. When the conductive brush 5 passes through, the magnetic strips are opened, improving the safety of use.

A conductive brush 5 is installed at one end of the slide 2, and the other end passes through a side wall of the frame 10 and is bolted to a positioning element 9. The positioning element 9 is bolted to the inner side of the side wall of the frame 10. The positioning element 9 is an L-shaped plate structure. The side wall of the frame 10 has a through hole for the slide 2 to pass through, and the slide 2 has a strip hole for connecting to the positioning element 9, so that the positioning element 9 can adapt to different side walls of the frame 10.

[0034] The frame 10 includes a rectangular frame and a cross inside the rectangular frame. Both the rectangular frame and the cross are made of aluminum profiles. The frame frame 11 is a double-row wooden strip double-pin structure.
