DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] The utility model provides a RV roof-raising nesting doll mechanism, such as Figure 1-8As shown, it includes a freely liftable enclosure 1 on the top of the RV, and a lifting column 3 is embedded and installed at the four end corners of the enclosure 1. The tops of the four lifting columns 3 are connected to a jacking 2 that matches the outer contour of the enclosure 1. The jacking 2 follows the extension and retraction of the four lifting columns 3 and freely forms a liftable space with the enclosure 1. A rolling mechanism is embedded inside the rolling curtain 4 of the jacking 2 and adaptively embedded according to the size of the side length. A rolling curtain 4 is rolled up at each rolling mechanism, and a counterweight plate 5 is connected to the end of the rolling curtain 4. Guide rails 6 are bolted on both sides of each lifting column 3, and both sides of the rolling curtain 4 are embedded in the guide rails 6 and are retracted and released by the rolling mechanism. When the counterweight plates 5 at the bottom of the four rolling curtains 4 are completely loosely placed on the top surface of the enclosure 1, the four rolling curtains 4 cooperate with the enclosure 1 and the jacking 2 to form an independent space separated from the external environment.

[0031] When in use, the jacking 2 is lifted up by four lifting columns 3, so that an open space with a height is formed between the enclosure 1 and the jacking 2, and the four rolling curtains 4 on the four sides can be loosened by the set rolling mechanism, so that the four rolling curtains 4 cooperate with the enclosure 1 and the jacking 2 to form an independent space separated from the external environment, which greatly improves the privacy of the nesting doll mechanism, and can provide shelter from wind and rain, greatly improving the practicability of the nesting doll mechanism.

[0032] It can be explained here that the four winding mechanisms can work independently, that is, one or more sides can be shielded.

[0033] As one of the embodiments, Figure 2 As shown, the rolling curtain 4 is composed of a plurality of door panels 41 movably connected end to end in sequence so that the plurality of door panels 41 can be rolled up onto the rolling mechanism, and a counterweight plate 5 is connected to the bottom of a door panel 41 at the end.

[0034] The door panels 41 that can be movably connected to each other are used to cooperate with the winding mechanism to realize the winding of the rolling curtain 4, thereby reducing the space occupied by the rolling curtain 4 when not in use. The counterweight plate 5 is used to give the rolling curtain 4 a downward pulling force in the initial release stage to ensure that the rolled-up curtain 4 falls smoothly.

[0035] Furthermore, a groove 42 is provided at the top of the door panel 41, a baffle 421 is provided at the opening of the groove 42, a hook 43 is provided at the bottom of the door panel 41, and two upper and lower adjacent door panels 41 are movably connected by the hook 43 and the baffle 421.

[0036] Furthermore, the hook 43 includes a bent portion 431 and an extending portion 432 that are integrally arranged. The 431 is located in the groove 42 and is limited by the baffle 421 , and the extending portion 432 is connected to the door panel 41 .

[0037] It can be explained here that the extension portion 432 can be an arc-shaped plate-like structure or a vertical plate-like structure.

[0038] Furthermore, an active space is formed between the curved portion 431 and the groove 42 so that the extension portion 432 can be located inside or outside the groove 42 , and the active space is the range of the connection gap between the upper and lower door panels 41 .

[0039] Furthermore, a plurality of light-transmitting holes 45 are formed on the extension portion 432 so that when the extension portion 432 is located outside the groove 42 , light can pass through the light-transmitting holes and enter the independent space.

[0040] The upper and lower adjacent door panels 41 are placed in the groove 42 through the bent hook 43 to hang the baffle 421. Under the action of gravity, the bent portion 431 hooks the baffle 421, that is, a gap is formed between the bottom door panel 41 and the top door panel 41, so that the extension portion 432 is located outside the groove 42, exposing the light-transmitting hole 45 for light transmission, making the enclosed space light-transmitting, avoiding the sealed space from being in a dark environment, and allowing air to flow freely to ensure that the sealed space will not feel stuffy.

[0041] It can be explained here that when the counterweight plate 5 continues to fall and contacts the top surface of the enclosure 1 and effectively supports the counterweight plate 5, the upper and lower door panels 41 are in contact, that is, the extension portion 432 is completely placed in the groove 42. At this time, there is no gap between the upper and lower adjacent door panels 41, so that the two adjacent door panels are fitted together, achieving complete sealing of the independent space and improving the selectivity of use.

[0042] Furthermore, the door panel 41 is a hollow structure, and the interior of the hollow structure is filled with an insulation layer 44. The insulation material is selected from one of glass wool and polyurethane to insulate the sealed space to prevent the external environment from being overheated or overcooled and affecting the experience inside the environment.

[0043] As one of the embodiments, two symmetrical assembly grooves 61 are provided at one end of the guide rail 6, and the assembly groove 61 is located at the front end of the guide rail 6. A brush 62 adapted to the assembly groove 61 is provided inside the two assembly grooves 61. At this time, the brush 62 contacts the part of the rolling curtain 4 that is slidably placed inside the guide rail 6. In this embodiment, the guide rail 6 is used to limit the predetermined track movement of the rolling curtain 4 when it is lifted or lowered to avoid swinging. The assembly groove 61 and the brush 62 are mainly used to prevent the sound made by the rolling curtain 4 contacting the guide rail 6 when it is lifted or lowered.

[0044] As one of the embodiments, two symmetrical assembly grooves 61 are provided at one end of the guide rail 6, and the assembly grooves 61 are the same length as the side walls of the guide rail 6. A brush 62 adapted to the assembly groove 61 is provided inside the two assembly grooves 61. At this time, the brush 62 is in complete contact with the rolling curtain 4 slidably placed inside the guide rail 6. In this embodiment, the guide rail 6 is used to limit the predetermined track movement of the rolling curtain 4 during lifting and lowering to avoid swinging. The assembly grooves 61 and the brushes 62 prevent the rolling curtain 4 from making a sound when contacting the guide rail 6 during lifting and lowering, and at the same time seal the guide rail 6 to prevent dust and impurities from entering the guide rail 6. At the same time, the rolling curtain 4 that enters the guide rail 6 can also be cleaned.

[0045] As one of the embodiments, the winding mechanism includes a reducer 7 and a winding drum 8, both of which are placed at the edge of the jacking 2, and the output shaft of the reducer 7 is connected to one end of the winding drum 8. The reducer 7 drives the winding drum 8 to rotate so that the winding drum 8 can reel in or loosen the rolling curtain 4 wound on its surface. When loosening, the reducer 7 drives the winding drum 8 to rotate to loosen the rolling curtain 4 wound on the surface of the winding drum 8. When rolling up, the reducer 7 drives the winding drum 8 to rotate in the opposite direction to roll up the rolling curtain 4.

[0046] Several points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
