[0001] The invention relates to the technical field of increasing the interior space of a vehicle, and in particular to a cantilever vehicle box slide-out system. Background Art

[0002] Existing vehicles and RVs are equipped with slide-out boxes to increase the usable space inside the RV. The outer wall of the slide-out box is flush with the outside of the vehicle during driving. When the vehicle stops, the slide-out box slides outward from the opening of the vehicle, thereby increasing the internal usable space of the vehicle.

[0003] US201615339481A discloses a device in which the slide-out mechanism is located under the vehicle body, has no integrated arrangement, occupies a large space, is inconvenient to install, and operates unsteadily.

[0004] US7293814B2 discloses a vehicle slide-out frame, in which the slide-out mechanism is also located below the slide-out box. After the entire slide-out box is extended, the slide-out extension mechanism below will be directly exposed, which makes installation complicated and affects the overall aesthetics.

[0005] US11964606B2 discloses a mechanism disposed between a vehicle opening frame and a slide-out box. Since there is a driving mechanism between the two, the gap between the two is too wide, which makes the overall vehicle unsightly and reduces the service life of the equipment.

[0052] Reference Figure 13-14 As shown, the cantilever moving assembly 30, the driving device 34, the Z-shaped connecting plate 4 and the supporting frame 5 are integrated inside the carrying box 3. The two carrying boxes 3 have the same structure and move synchronously, and together constitute a vehicle slide-out system, so that the slide-out box 2 can slide out and be retracted from the opening of the vehicle body 1.

[0053] Reference Fig.15 As shown, when the slide-out system slides out, the first guide rail 307 and the second guide rail 309 of the cantilever moving assembly 30 slide out to the maximum position through two-stage telescopic movement, and the rack 302 of the driving device 34 also moves to the longest distance, and the cantilever moving assembly is suspended in the air to bear the weight of the slide-out box.

The cantilever moving assembly is still suspended in the air to bear the weight of the slide-out box.

[0055] Reference Fig.17As shown: when the slide-out box 2 of the vehicle slide-out system slides out, the motor 303 of the drive device 34 drives the gear 304 to rotate through the reducer 305, and the tooth surface of the gear 304 meshes with the tooth surface of the rack 302, converting the rotational motion of the gear 304 into the linear motion of the rack 302, and the rack 302 and the rack frame 311 move together with the carrying box 3, and the carrying box 3 drives the second guide rail 309 to slide. During the sliding process, when the third limit plate 310A hits the third baffle 308A of the Z-shaped connecting plate 4, the Z-shaped connecting plate 4 drives the first slider 312 to move, and when the first limit plate 301A of the first guide rail 307 hits the first baffle 306A of the support frame 5, the sliding process ends, the movement stops, and the slide-out box 2 slides out completely. At this time, the weight of the slide-out box 2 is transferred to the cantilever moving assembly 30 through the carrying box 3, and the cantilever moving assembly 30 and the Z-shaped connecting plate 4 transfer the weight to the support frame 5, and the support frame 5 transfers the weight to the vehicle body 1. The support frame 5 supports the entire slide-out box 2, and the installation is convenient and simple.

[0056] Reference Fig.18 As shown: when the slide-out box of the vehicle slide-out system is retracted, the motor 303 drives the gear 304 to reverse through the reducer 305, and the gear 304 drives the rack 302 to move in the opposite direction. The rack 302 drives the carrying box 3 to move toward the inside of the opening of the vehicle body 1 through the rack frame 311, and the carrying box 3 then drives the second guide rail 309 to slide inward. During the sliding process, when the fourth limit plate 310B hits the fourth baffle 308B of the Z-shaped connecting plate 4, the Z-shaped connecting plate 4 drives the first slider 312 to move. When the second limit plate 301B of the first guide rail 307 hits the second baffle 306B of the support frame 5, the retraction process ends and the movement stops, and the box is completely retracted.
