[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] like Figures 1 to 4 As shown, the utility model provides a vehicle-mounted air cushion device, including a support mechanism configured to switch between an unfolded state and a folded state, an airbag cushion 2 arranged on the support mechanism, and an inflation mechanism connected to the airbag cushion 2 and used to inflate the airbag cushion 2. During the inflation process of the airbag cushion 2, the support mechanism is driven to switch from the folded state to the unfolded state.

[0028] Specifically, if Figure 1 and Figure 2 As shown, the support mechanism includes a lower support plate 3 and an upper support plate 1 rotatably connected to the lower support plate 3, and the airbag cushion 2 is connected to the upper support plate 1 and the lower support plate 3. One end of the upper support plate 1 is rotatably connected to one end of the lower support plate 3, and the upper support plate 1 can rotate up and down relative to the lower support plate 3. When the support mechanism is in a folded state, the airbag cushion 2 is not inflated, the airbag cushion 2 is sandwiched between the upper support plate 1 and the lower support plate 3, and the upper support plate 1 is located above the lower support plate 3. During the inflation process, the airbag cushion 2 pushes the upper support plate 1 to rotate until the upper support plate 1 rotates to the same horizontal height position as the lower support plate 3, and the inflated airbag cushion 2 is laid flat on the upper support plate 1 and the lower support plate 3.

[0029] like Figure 1 and Figure 2 As shown, the vehicle-mounted air cushion device of the utility model also includes a lower storage box 4, a lower support plate 3 is arranged on the lower storage box 4, the lower storage box 4 is located below the lower support plate 3, and the lower storage box 4 and the lower support plate 3 are located behind the rear seat 5.

[0030] like Figure 3 As shown, the inflation mechanism includes an air pump 6, a first valve 9 connected to the air outlet 7 of the air pump 6, and a second valve 10 connected to the air inlet 8 of the air pump 6. The first valve 9 and the second valve 10 are connected to the airbag cushion 2. The first valve 9 and the second valve 10 are three-way valves.

[0031] When in use, the rear seat 5 is automatically laid down first, at which time the airbag cushion 2 begins to inflate. The inflated airbag cushion 2 will lift up the upper support plate 1 and unfold it to form a large air cushion bed. After use, the airbag cushion 2 is evacuated and contracted by the air pump 6. At this time, the rear seat 5 is lifted, and the rear seat 5 will drive the upper support plate 1 to rotate. The upper support plate 1 presses the air cushion underneath to achieve quick storage. After storage, it will not affect the normal use of the trunk, thereby maximizing space utilization.

[0032] Preferably, the air pump 6 is a vacuum diaphragm pump. The vacuum diaphragm pump has an air inlet 8 and an air outlet 7. When the vacuum diaphragm pump is started, the first valve 9 connects the air outlet 7 with the air cushion, the second valve 10 is closed, and the airbag cushion 2 is inflated and deployed; when the airbag cushion 2 is stowed, the first valve 9 and the second valve 10 are switched to realize vacuuming of the airbag cushion 2.

[0033] When inflation is required, the air pump 6 is started, the first valve 9 connects the air outlet end 7 and the airbag cushion 2, the second valve 10 is closed, and the airbag cushion 2 is inflated and deployed; when stowed, the first valve 9 and the second valve 10 are switched, the second valve 10 connects the air inlet end 8 and the airbag cushion 2, the first valve 9 is closed, and the airbag cushion 2 is evacuated.

[0034] Preferably, an air suction port 12 is installed at the air inlet end 8 of the air pump 6, and the opening and closing of the air suction port 12 is controlled by an electric control valve. The air suction port 12 can be used to evacuate and compress the vacuum storage bag containing supporting supplies such as quilts, so as to maximize the utilization rate of the space in the vehicle.

[0035] Preferably, the support mechanism further includes an inner support plate movably arranged on the upper support plate 1 and support legs connected to the inner support plate. An inner cavity for accommodating the inner support plate is arranged on the upper support plate 1, and the upper support plate 1 is an internally hollow structure. One end of the upper support plate 1 is rotatably connected to the lower support plate 3, and the other end of the upper support plate 1 is provided with an opening for the inner support plate to pass through. After the support mechanism is in the unfolded state, the inner support plate in the upper support plate 1 can be pulled outward, and then the two support legs rotatably connected to the inner support plate can be rotated downward to open. The two support legs provide support for the inner support plate, so that the inner support plate can be used more stably. The arrangement of the inner support plate can expand the use space.

[0036] like Figure 4As shown, the airbag cushion 2 includes a fabric layer 15, an elastic layer 16, a support layer 17, a water-heating layer 18, a heat-insulating layer 19 and an air cushion layer 20 arranged in sequence. The fabric layer 15, the elastic layer 16, the support layer 17, the water-heating layer 18, the heat-insulating layer 19 and the air cushion layer 20 are arranged in sequence from top to bottom. The water pipe in the water-heating layer 18 is connected to the water tank. The semiconductor refrigeration sheet or compressor in the water tank heats / cools the water in the water tank, and the water is transported to the water-heating layer 18 by a submersible pump for temperature adjustment. This design consumes less power, has low noise, adopts heat conduction technology, and has a water-electricity separation design, without leakage and fire hazards.

[0037] The utility model also provides a vehicle, including the vehicle-mounted air cushion device of the above structure. The specific structure of the vehicle-mounted air cushion device can be referred to Figures 1 to 4 Since the vehicle of the utility model includes the vehicle-mounted air cushion device in the above embodiment, it has all the advantages of the above vehicle-mounted air cushion device.

[0038] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
