[0038] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the specific embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0039] As Figures 1-4 shown, a flap sinking device for a motorhome of the present utility model includes a mounting seat 1, a sinking bracket 2 and a parallelogram mechanism 3.

[0040] Among them, the mounting seat 1 is in a U shape with an open top, which is used for fixedly connecting the motorhome. The upper end of the mounting seat 1 is connected to the upper end of the sinking bracket 2 through the parallelogram mechanism 3. The lower end of the sinking bracket 2 is connected to the flap 7 through a hinge. The flap 7 is used to expand the use space of the motorhome. When used outdoors, the flap 7 is turned downward and opened to be in a horizontal state. At this time, the plane on the top of the flap 7 can be used as needed.

[0041] To improve the stability of the flap 7 after it is opened, a wire rope 4 is provided on one side of the flap 7 after it is opened. Among them, one end of the wire rope 4 is detachably connected to the side of the sinking bracket 2, and the other end is detachably connected to the side of the flap 7. Through the wire rope 4, a triangular structure is formed among the flap 7, the sinking bracket 2 and the wire rope 4, and the stability is relatively good. At the same time, since the wire rope 4 is detachable, it is convenient to store the wire rope 4.

[0042] The above-mentioned wire rope 4 is installed in a hanging manner. Specifically, a hook 5 is fixed at the upper end of one side of the sinking bracket 2 and at the middle position of one side of the flap 7 respectively. One end of the wire rope 4 is hung on one of the hooks 5, and the other end is hung on the other hook 5. Among them, the hook 5 is a bolt structure or a hanging spring column structure, and hanging holes are provided at both ends of the wire rope 4.

[0043] There are two parallelogram mechanisms 3, which are symmetrically arranged on both sides of the sinking bracket 2, and the two parallelogram mechanisms 3 are arranged inside the mounting seat 1. As Figure 4 shown, the mounting seat 1 and the sinking bracket 2 form a first folding mechanism through the parallelogram mechanism 3, and the sinking bracket 2 and the flap 7 form a second folding mechanism through a hinge. When the flap 7 is not needed, the flap 7 and the sinking bracket 2 can be folded in sequence as Figure 4 demonstrated, so that the flap 7 is stored on one side of the vehicle body. Then, the upper end of the flap 7 is fixed to the vehicle body through the side bin lock 6 fixed on the flap 7. A lock is provided on the vehicle body, and this lock and the side bin lock 6 can be locked with each other.

[0044] To achieve the shape variability of the parallelogram mechanism 3, the parallelogram mechanism 3 includes a first hinge plate 31 and a second hinge plate 32. Among them, the first hinge plate 31 and the second hinge plate 32 are of equal length and are arranged in parallel. The first hinge plate 31 is arranged above the second hinge plate 32. One end of the first hinge plate 31 and the second hinge plate 32 is aligned vertically and is selectively hinged or fixedly connected to the upper end of the mounting seat 1 by means of bolt fixation, and the other end is aligned vertically and is selectively hinged or fixedly connected to the upper end of the sinking bracket 2 by means of bolt fixation.

[0045] When the height of the sinking bracket 2 needs to be adjusted, loosen the connection bolts of the first hinge plate 31 and the second hinge plate 32. At this time, the two ends of the first hinge plate 31 and the second hinge plate 32 can be hinged to the mounting seat 1 and the sinking bracket 2 at the corresponding positions. At this time, the position of the sinking bracket 2 can be adjusted. During the adjustment process, the parallelogram mechanism 3 deforms. After adjustment, tighten the connection bolts of the first hinge plate 31 and the second hinge plate 32 to fix the deformed shape of the parallelogram mechanism 3. Through deformation, the height of the sinking bracket 2 can be adjusted, and further the use height of the flap 7 can be adjusted, greatly improving the convenience of using the flap 7.

[0046] To achieve the above functions, the parallelogram mechanism 3 further includes locking bolts 33. Among them, one locking bolt 33 penetrates through each of the two ends of the first hinge plate 31 and the second hinge plate 32; the locking bolt 33 provided at one end of the first hinge plate 31 and the second hinge plate 32 is screwed to the mounting seat 1, and the locking bolt 33 at the other end is screwed to the sinking bracket 2. When the parallelogram mechanism 3 needs to deform, loosen the locking bolts 33. At this time, the locking bolts 33 are used as rotation axes, and the four corners of the parallelogram mechanism 3 can be flexibly deformed. On the contrary, after tightening the locking bolts 33, the locking bolts 33 are used as fastening bolts to fix the shape of the parallelogram mechanism 3.

[0047] Further, the parallelogram mechanism 3 further includes nuts 34. Specifically, one nut 34 is fixed at each position on the mounting base 1 and the sinking bracket 2 corresponding to the position of the locking bolt 33. One end of the locking bolt 33 is screwed with the nut 34 at the corresponding position. By providing the nut 34, the stability of the installation of the locking bolt 33 is improved.

[0048] In the above structure, first light holes 301 are transversely provided through both ends of the first hinge plate 31 and the second hinge plate 32. One end of the locking bolt 33 passes through the first light hole 301 at the corresponding position. Second light holes 302 are transversely provided through the mounting base 1 and the sinking bracket 2 at the position corresponding to the locking bolt 33. After one end of the locking bolt 33 passes through the second light hole 302 at the corresponding position, it is then screwed with the nut 34 at the corresponding position. In addition, washers are provided between the first hinge plate 31 and the mounting base 1, between the first hinge plate 31 and the sinking bracket 2, between the second hinge plate 32 and the mounting base 1, and between the second hinge plate 32 and the sinking bracket 2. Specifically, the washers are installed on the locking bolt 33 at the corresponding positions.

[0049] The usage method of a flip-down device for a motorhome according to the present utility model is as follows:

[0050] When the flip plate 7 needs to be used, open the side compartment lock 6, flip the flip plate 7 downward to open it, loosen the locking bolt 33, adjust the position of the sinking bracket 2 up and down, and adjust the level of the flip plate 7. After adjustment, tighten the locking bolt 33.

[0051] After use, loosen the locking bolt 33, fold the flip plate 7 and the sinking bracket 2 onto the mounting base 1, and then close the side compartment lock 6.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
