[0028] The following is combined with Figure 1 -Attached Figure 5 The utility model is described in further detail.

[0029] The utility model embodiment discloses a caravan card seat expansion mechanism.

[0030] Reference Figure 1 and Figure 2 The caravan deck expansion mechanism is installed on one side of the main deck 1, and includes an expansion plate 2, a support rod 3 and a support plate 4. Two support rods 3 are vertically arranged and fixed to one side of the main deck 1 by bolts. The expansion plate 2 is hinged to the top of the two support rods 3. The expansion plate 2 is a rectangular plate and a rectangular receiving groove 20 is opened on its bottom surface. Two support plates 4 are symmetrically arranged and correspond to the positions of the two support rods 3. The support plate 4 is a right-angled triangular plate and is hinged to the bottom wall of the receiving groove 20. When the support plate 4 is folded in the receiving groove 20, the outer surface of the support plate 4 is flush with the bottom surface of the expansion plate 2.

[0031] Reference Figure 2 and Figure 3 A hand-gripping groove 40 is provided on the surface of the support plate 4, so that the user can flip the support plate 4 to make it perpendicular to the expansion plate 2, and the support plate 4 is movably in contact with the support rod 3. A magnet bar 41 is installed on the side of the support plate 4 away from the hand-gripping groove 40, and a magnet or iron sheet matching it is embedded on the bottom wall of the receiving groove 20. When the support plate 4 is folded into the receiving groove 20, the support plate 4 can be stably folded into the receiving groove 20 through the magnetic attraction of the magnet bar 41.

[0032] Reference Figure 3 and Figure 4 In order to enhance the stability of the support plate 4 when the support plate 4 abuts against the support rod 3, the expansion mechanism further includes a limit assembly 5 for limiting the flipping of the support plate 4 and a control assembly 6 for controlling the operation of the limit assembly 5. The limit assembly 5 includes a clamping plate 50 with a U-shaped cross section, the opening of the clamping plate 50 faces the side close to the support plate 4, and the clamping plate 50 is used to clamp the support plate 4. A mounting groove 30 for accommodating the clamping plate 50 is provided on the side wall of the support rod 3, and the clamping plate 50 is laterally slidably connected in the mounting groove 30. Two springs 51 are also connected between the clamping plate 50 and the bottom wall of the mounting groove 30, and the springs 51 have a tendency to elastically drive the clamping plate 50 to move toward the direction close to the support plate 4.

[0033] Reference Figure 4 Two coaxially arranged mounting holes 31 are horizontally opened on the support rod 3, and the mounting holes 31 are connected to the mounting groove 30. A rectangular clearance hole 500 is opened on the side wall of the clamping plate 50 corresponding to the mounting hole 31, and a semi-arc-shaped clamping groove 501 is set at the bottom of the clearance hole 500 away from the support plate 4.

[0034] Reference Figure 4 and Figure 5 The control assembly 6 includes a transmission rod 60 that is rotatably inserted through the mounting hole 31, the clearance hole 500 and the mounting groove 30. A driving rod 61 for driving the clamping plate 50 to move into the mounting groove 30 is fixedly connected to the transmission rod 60. The driving rod 61 is ellipsoidal and has good anti-bending performance. The driving rod 61 is arranged in the clearance hole 500. A knob 62 for driving the transmission rod 60 to rotate radially is installed at the end of the transmission rod 60. A rubber sleeve 63 sleeved on the clamping plate 50 is also arranged at the clamping groove 501. The rubber sleeve 63 is fixed to the clamping plate 50 by a screw 64. The rubber sleeve 63 is adapted to the clamping groove 501. The rubber sleeve 63 has good elastic deformation performance, so that the driving rod 61 is easily fixed.

[0035] The implementation principle of the caravan seat expansion mechanism of the embodiment of the utility model is: when the expansion plate 2 is not in use, the expansion plate 2 is in a folded state, which can shield the internal equipment or components of the main seat 1 without occupying the internal space of the caravan and affecting the user's normal walking.

[0036] When the expansion board 2 is needed, the user first flips the expansion board 2 upwards by 90° to make the expansion board 2 flush with the seat surface of the main seat 1, and then flips the support board 4 outwards by 90° through the finger groove 40 to make the support board 4 vertical and abut against the support rod 3. Then, the knob 62 is rotated 90° counterclockwise to move the end of the driving rod 61 out of the clamping groove 501. At this time, the spring 51 elastically stretches to drive the clamping plate 50 to clamp on the support board 4, thereby limiting the flipping of the support board 4 and maintaining the stability of the support board 4. The user can sit with confidence.

[0037] When the expansion board 2 is finished, the user rotates the knob 62 90° clockwise, and the driving rod 61 rotates synchronously and pushes the clamping plate 50 to move inside the installation slot 30, and the spring 51 is elastically compressed until the end of the driving rod 61 is clamped into the clamping slot 501. At this time, the clamping plate 50 releases the restriction on the support plate 4, and the user can flip the support plate 4 inward 90° and fix the support plate 4 in the receiving slot 20 through the magnet bar 41, and finally flip the expansion board 2 downward 90° to fold it.

[0038] The expansion mechanism is very easy to operate. The expansion board 2 can be supported by the foldable support plate 4. Compared with the common rod support in the prior art, it has higher strength, better stability and stronger practicality. The expansion mechanism is fixed to the main deck 1 by bolts, which is convenient for the installation or displacement of the expansion mechanism to adapt to more usage scenarios. The expansion board 2 increases the usable area of ​​the main deck 1 seat. Users can use this area to sit or rest. The expansion board 2 can usually be used as a cover for the power distribution panel under the main deck 1 to prevent people in the car from accidentally operating the power distribution switch.

[0039] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
