firstly, sliding the second connecting part 71b and the second group of floor board block assemblies 60b thereon to the rear of the first connecting part 71a, and lowering the second group of floor board block assemblies 60b to the same height as the first group of floor board block assemblies 60a on the first connecting part 71a through the swing arm 702;

then, the second floor panel block 62 and the fourth floor panel block 64 slide to one side of the vehicle along the corresponding connecting shafts;

then, the fourth floor panel 64, the third connecting portion 72a connected to the fourth floor panel 64, and the stacked body supported on the fourth floor panel 64 are taken down together from the vehicle side;

then, the second floor panel 62, the third connecting portion 72a connected to the second floor panel 62, and the stacked body supported on the second floor panel 62 are removed together from the vehicle side;

then, the third floor panel 63 and the first floor panel 61 are slid to the vehicle side along the corresponding connecting shafts;

then, the third floor panel 63, the fourth sliding portion 72b and the second sliding portion 71b connected to the third floor panel 63, and the stacked body supported on the third floor panel 63 are removed together from the vehicle side;

then, the first floor panel 61, the fourth connecting portion 72b and the first connecting portion 71a connected to the first floor panel 61, and the stacked body supported on the first floor panel 61 are taken down together from the vehicle side;

after removal, the first connecting portion 71a and the second connecting portion 71b are slidably attached together, and the third connecting portion 72a and the fourth connecting portion 72b are slidably attached together, so that they can be pulled out and stored in blocks by means of a moving pulley (not shown) on the floor panel.

As shown in fig. 7, the first connecting means 71 may also be provided with a plurality of laterally extending sleeves for receiving the main legs 101a of the floor stand 101. In the illustrated embodiment, three sleeves are provided, a first sleeve 71d, a second sleeve 71e and a third sleeve 71 f. As shown in fig. 14, the top ends of the main legs 101a are connected with sliding rods 101d, when the vehicle-mounted house is in an unfolded state, the sliding rods 101d at the top ends of the three rows of main legs 101a are respectively inserted into the three sleeves, and the three rows of main legs 101a are spaced at a distance in the front-back direction to ensure the supporting stability. The lower end of the swing arm 702 may also be hinged to the sleeve.

As shown in fig. 7, the first sleeve 71d is connected between the two sliders 701 of the first connection portion 71a, the second sleeve 71e is located at the rear side of the first sleeve 71d, the second sleeve 71e is connected between the two sliders 701 of the second connection portion 71b, and the third sleeve 71f is located at the front side of the first sleeve 71 d.

Specifically, the third sleeve 71f has two connection modes, and in fig. 9, the third sleeve 71f is connected between the two sliding members 701 of the first connection portion 71 a. In fig. 7, the first connecting device 71 is provided with a fifth connecting portion 71c, the fifth connecting portion 71c includes two sliding members 701 parallel to each other, the two sliding members 701 of the fifth connecting portion 71c are slidably and guided to be engaged with the two sliding members 701 of the first connecting portion 71a, respectively, and can slide back and forth relative to the first connecting portion 71a, and the third sleeve 71f is connected between the two sliding members 701 of the fifth connecting portion 71 c.

The third socket 71f is connected between the two sliding members 701 of the fifth connecting portion 71c, so that the positions of the third socket 71f, the slide bar 101d inserted in the third socket 71f, and the main leg 101a connected to the slide bar 101d can be changed by sliding the fifth connecting portion 71 c. Furthermore, the third sleeve 71f can be used to define the swing angle of the swing arm 702 of the first connection portion 71a, so that the in-vehicle room can be in two storage states.

Specifically, as shown in fig. 2 and 5, when the fifth connecting portion 71c slides backward to the limit position relative to the first connecting portion 71a, the third sleeve 71f stops the swing arm 702 of the first connecting portion 71a, or by similar means, the swing arm 702 of the first connecting portion 71a cannot swing downward any more after swinging to the illustrated position, and therefore, the swing arm 702 of the first connecting portion 71a and the floor panel supported thereon can only be stored in the first storage state shown in fig. 2, and cannot fall into the frame enclosed by the third sleeve 71f, the two sliding members 701 of the first connecting portion 71a and the first sleeve 71 d. The auxiliary leg 101c is receivable in a frame surrounded by the third sleeve 71f, the two sliders 701 of the first connecting portion 71a, and the first sleeve 71 d.

As shown in fig. 3 and 6, after the fifth connection portion 71c slides forward for a distance relative to the first connection portion 71a, the third sleeve 71f no longer stops the swing arm 702 of the first connection portion 71a, and a sufficient space is left between the first sleeve 71 and the third sleeve 71f, so that the swing arm 702 of the first connection portion 71a can swing to the frame enclosed by the third sleeve 71f, the two sliding members 701 of the first connection portion 71a and the first sleeve 71d, and accordingly, the floor panel supported on the first connection portion 71a can descend for a distance further than in the first storage state. With this arrangement, the first connecting portion 71a, the second connecting portion 72b, and the fifth connecting portion 71c occupy the height of the storage body in the second storage state not only exclusively or only very little to meet the height requirement of the vehicle roof storage, and/or the vehicle-mounted room can be designed with a wider storage body height.

As shown in fig. 2 and 3, the length L1 of the housing in the first storage state is shorter than the length L2 of the housing in the second storage state, so that the planar area occupied by the housing in the first storage state is slightly smaller. The height H1 of the container in the first storage state is higher than the height H2 of the container in the second storage state, and the second storage state more easily satisfies the height requirement of the vehicle roof storage. With this arrangement, the user can freely select the storage state according to the needs and the vehicle type, for example, when the vehicle is installed in a carriage or a pickup truck cargo compartment, the first storage state is more advantageous.
