[0036] As shown in Figures 1 to 13 The embodiment provides a kind of inflatable enclosure device of lift top motor home, including four lift columns 2 in the corner of motor home 1, inflatable lifting enclosure 4 in wave shape is folded in the roof storage slot 3 between two adjacent lift columns, the end side of the inflatable lifting enclosure is embedded in the vertical guide slot 5 of corresponding lift column, the vertical guide slot is provided with clamping recess 6 in the position near bottom terminal point, and the both ends of the top of inflatable lifting enclosure are provided with spring telescopic clamping part, and the end of spring telescopic clamping part is rolled with vertical guide slot or embedded in clamping recess by roller 7.

[0037] Inflatable lifting enclosure is used, and the surrounding effect is good, so as to avoid that article or personnel falls from the top layer of motor home.When four lift columns start to lift, roller is first rolled with vertical guide slot, and when clamping recess rises to roller position, roller is embedded in clamping recess under the action of spring telescopic clamping part, so that lift column carries inflatable lifting enclosure and synchronously rises, until lift column rises to position, to realize that the automatic formation of enclosure protection after lift column lifts.

[0038] In the embodiment of the utility model, the storage slot is set at the four peripheral edges of the second floor of the roof, and is used to hide the inflatable lifting enclosure in the folded state. The lifting structure and principle of the lift column and the setting of the second floor all belong to the prior art, and will not be described in detail here.

[0039] In the embodiment of the utility model, the top of the four lift columns is fixedly connected with a ceiling 8, and the peripheral edge of the ceiling is provided with a sealing groove 9 for embedding the top of the inflatable lifting enclosure.

[0040] In the embodiment of the utility model, vertical guide slots are arranged on the lift columns at the two end sides of the inflatable lifting enclosure, and a plurality of guide blocks 10 for embedding in the corresponding vertical guide slots are vertically and uniformly arranged at the two end sides of the inflatable lifting enclosure.

[0041] In the embodiment of the utility model, the cross-sectional shape of the vertical guide slot and the guide block is "convex" shape.

[0042] In the embodiment of the utility model, rigid handrails 11 are fixedly arranged at the top of the inflatable lifting enclosure, and the spring telescopic clamping parts are arranged at the two ends of the handrails.

[0043] In the embodiment of the utility model, the spring telescopic clamping parts all include spring pins 12 installed at the end of the handrail, the axial direction of the spring pins is the length direction of the handrail, and the rollers are all installed at the outer protruding end of the spring pins to roll.

[0044] In the embodiment of the utility model, the bottom of the inflatable lifting fence is fixedly connected to the groove bottom of the receiving groove, and the bottom of the inflatable lifting fence is provided with an air inlet 13 and an air outlet 14, the air inlet is connected to the inflator through an air inlet pipeline and an air inlet electromagnetic valve, and the air outlet is provided with an air outlet electromagnetic valve.

[0045] In the embodiment of the utility model, the inside of the inflatable lifting fence is fixedly connected with a support plate 15 between the wave crests or wave troughs horizontally corresponding to the two wave-shaped fence walls, and a plurality of air holes 16 are formed in the support plate.

[0046] In the embodiment of the utility model, the support plate has the function of making the inflatable lifting fence have a certain anti-deformation ability and improving the protection performance of the inflatable lifting fence. The air holes densely arranged on the support plate not only facilitate the rapid passage of airflow during inflation, but also help to reduce the weight of the support plate without weakening the supporting strength of the support plate.

[0047] In the embodiment of the utility model, the clamping recess is arranged at the upper one-third of the bottom end of the vertical guide groove.

[0048] In the embodiment of the utility model, the shape of the clamping recess is a right-angled trapezoid with the right angle side downward and the oblique side upward.

[0049] In the embodiment of the utility model, the top end of the lifting column is a closed end 17 for closing the top end of the vertical guide groove.

[0050] In the embodiment of the utility model, the working principle of the lifting top RV inflatable fence device is as follows:

[0051] 1. Fence mode: when the four lifting columns start to rise, the rollers first roll with the vertical guide groove, and the inflatable lifting fence does not rise; when the clamping recess rises to the roller position, the roller is embedded in the clamping recess under the action of the spring telescopic clamping part, so that the lifting column and the inflatable lifting fence rise synchronously, until the lifting column rises to the position, the inflatable lifting fence rises to 1 / 3 of the total lifting height, and the automatic formation of the fence protection after the column is lifted is realized, and the four directions can be observed when the weather is fine; at this time, the inflatable lifting fence does not need to be inflated, and can prevent people or objects from falling and play a protective role, as shown in Figure 1 、 5 , 6, 7.

[0052] 2. Semi-enclosed mode: Users can raise any one, two, or three of the four enclosures as needed, such as to control sunlight, wind direction, or view, to achieve a balcony viewing effect. In operation, the air inflator needs to be started to inflate the corresponding inflatable enclosure. This causes the enclosure to expand upwards, pushing the rollers upwards and gradually rolling them through the inclined edge of the locking recess to the vertical guide groove, where the spring pin retracts (e.g., ...). Figure 8 As shown), until the handrail is embedded in the sealing groove at the edge of the ceiling (as shown). Figure 13 (As shown).

[0053] 3. Fully Enclosed Mode: With all four inflatable lift-up barriers raised, the RV's elevated section is fully enclosed, entering a privacy living mode. This provides protection against wind, sand, sun, and noise. Figure 13 As shown.

[0054] In fully enclosed mode, after the handrail is embedded in the sealing groove at the edge of the roof, a certain amount of gas is continued to be injected into the inflatable lifting barrier, so that the entire interior of the inflatable lifting barrier is filled with air. This causes the left and right edges of the inflatable lifting barrier to expand and fill the gap between them and the vertical guide groove, the bottom edge of the inflatable lifting barrier to expand and fill the gap between it and the roof storage groove, and the top edge of the inflatable lifting barrier to expand and fill the gap between it and the sealing groove, thereby improving the sealing effect of the inflatable lifting barrier in fully enclosed mode.

[0055] like Figures 9 to 12 As shown, when lowering the barrier, clear the top layer of items from the vehicle roof. For inflatable lifting barriers, open the deflation solenoid valve to release air. Then, press the inflatable lifting barrier down until its rollers re-engage the locking recesses, allowing personnel to descend from the roof. The four lifting pillars then begin to descend, with the rollers gradually rolling along the inclined edge of the locking recesses to the vertical guide grooves until the closed end of the top of the lifting pillar touches the roller. The closed end then lowers synchronously with the inflatable lifting barrier. After the lifting pillars have reached their final position, the inflatable lifting barrier folds into the storage compartment.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
