[0028] As Figures 1 to 6As shown, a motor home lifting roof comprises a motor home lifting roof base 1, the top surface of the motor home lifting roof base 1 is provided with an extrusion type sealing assembly 5, the bottom surface of the motor home lifting roof base 1 is provided with an elastic mechanical sealing assembly 6 for sealing the gap between the motor home lifting roof base 1 and the motor home roof, the motor home lifting roof base 1 is fixedly installed with a hollow rubber ring 7 to seal the gap between the motor home lifting roof base 1 and the elastic mechanical sealing assembly 6, and the bottom surface of the elastic mechanical sealing assembly 6 is embedded with at least two groups of hollow sealing rings 8 to seal the gap between the elastic mechanical sealing assembly 6 and the motor home roof. More specifically, the motor home lifting roof base 1 is installed on the motor home roof, the motor home lifting roof base 1 is vertically pressed by the fixing part, and then the elastic mechanical sealing assembly 6 and the hollow sealing ring 8 on the bottom surface thereof are compressed, the gap between the motor home lifting roof base 1 and the motor home roof is sealed by the elastic mechanical sealing assembly 6, and the gap between the bottom surface of the elastic mechanical sealing assembly 6 and the motor home roof is sealed by the hollow sealing ring 8 which is compressed and deformed, after the motor home lifting roof base 1 is fixed, the hollow rubber ring 7 is compressed by the compression of the elastic mechanical sealing assembly 6, and the gap between the motor home lifting roof base 1 and the elastic mechanical sealing assembly 6 is sealed by the hollow rubber ring 7.

[0029] The surface of the motor home lifting roof base 1 is provided with a plurality of installation holes 11, and the bottom surface of the motor home lifting roof base 1 is provided with a drainage groove 12. More specifically, the motor home lifting roof base 1 can be fixedly installed on the motor home roof by the fixing part through the plurality of installation holes 11 on the surface of the motor home lifting roof base 1.

[0030] The top surface of the motor home lifting roof base 1 is provided with a shearing type lifting mechanism 2, and the top end of the shearing type lifting mechanism 2 is fixedly installed with a lifting roof 3, the shearing type lifting mechanism 2 is used for vertically lifting the lifting roof 3, and the inner wall of the motor home lifting roof base 1 and the inner top of the lifting roof 3 are fixedly installed with a folding protective cover 4. More specifically, the lifting roof 3 can be vertically lifted by the shearing type lifting mechanism 2, when the lifting roof 3 is retracted, the top end of the lifting roof 3 and the motor home lifting roof base 1 are closed, the extrusion type sealing assembly 5 is compressed by the contact between the lifting roof 3 and the top surface of the extrusion type sealing assembly 5, the extrusion type sealing assembly 5 is deformed by compression, the extrusion type sealing assembly 5 is tightly attached to the inner wall of the lifting roof 3, and the gap between the motor home lifting roof base 1 and the lifting roof 3 is sealed.

[0031] The compression sealing assembly 5 includes a groove 501 formed on the top surface of the RV lift-top base 1, and a rubber strip 502 is fixedly installed on the surface of the groove 501. The rubber strip 502 has a U-shaped cross-section, and a rigid rubber pressure plate 503 is fixedly installed on the top surface of the rubber strip 502. The rigid rubber pressure plate 503 and the groove 501 are movably fitted together. More specifically, after the lift-top 3 is vertically retracted by the shear-type lifting mechanism 2, the top inner side of the lift-top 3 contacts the top surface of the rigid rubber pressure plate 503. The lift-top 3 drives the rigid rubber pressure plate 503 to move vertically downward on the groove 501 until it is flush with the top surface of the RV lift-top base 1, thereby compressing the rubber strip 502. The outer edge of the rubber strip 502 is compressed and deformed, causing a protrusion. This makes the surface of the rubber strip 502 tightly adhere to the inner wall of the lift-top 3, thereby sealing the gap between the lift-top 3 and the RV lift-top base 1.

[0032] The elastic mechanical seal assembly 6 includes a mounting groove 601 formed on the bottom surface of the RV pop-up roof base 1. Several sets of springs 602 are fixedly mounted on the top surface of the mounting groove 601, and rubber frames 603 are fixedly mounted on the bottom ends of the springs 602. The cross-section of the rubber frames 603 is L-shaped, and the rubber frames 603 are movably inserted into the mounting groove 601. More specifically, the assembly is fixed to the RV roof via mounting holes 11 on the surface of the RV pop-up roof base 1 using fasteners. At this time, the rubber frames 603 are vertically moved upwards within the mounting groove 601 due to the downward force exerted by the fasteners on the RV pop-up roof base 1, thus compressing the springs 602 and the hollow rubber ring 7. The spring force reaction of the springs 602 causes the rubber frames 603 to apply pressure to the hollow sealing ring 8, thereby deforming the hollow sealing ring 8 and sealing the gap between the rubber frames 603 and the RV roof.

[0033] The rubber strip 502, the hollow rubber ring 7, and the hollow sealing ring 8 are all made of elastic rubber material. More specifically, by using elastic rubber for the rubber strip 502, the hollow rubber ring 7, and the hollow sealing ring 8, they can be compressed and deformed.

[0034] The bottom surface of the RV pop-up roof base 1 is provided with a drainage groove 12, which is connected to the mounting groove 601. More specifically, the connection between the drainage groove 12 and the mounting groove 601 allows water in the mounting groove 601 to be drained, preventing water from accumulating in the mounting groove 601.

[0035] In summary: The RV pop-up roof base 1 is installed on the RV roof. The fixing components ensure vertical pressure on the RV pop-up roof base 1, thereby compressing the elastic mechanical seal assembly 6 and its bottom hollow sealing ring 8. The elastic mechanical seal assembly 6 then seals the gap between the RV pop-up roof base 1 and the RV roof. The deformation caused by the compression of the hollow sealing ring 8 seals the gap between the bottom surface of the elastic mechanical seal assembly 6 and the RV roof through multiple sets of hollow sealing rings 8. After the RV pop-up roof base 1 is fixed, the compression of the elastic mechanical seal assembly 6 compresses the hollow rubber ring 7, which in turn seals the gap between the RV pop-up roof base 1 and the elastic mechanical seal assembly 6.
