The left end of the central support frame assembly is connected to the left berth compartment assembly, and the right end of the central support frame assembly is hinged to the right support plate assembly. A support bracket is provided on the right side of the right support plate assembly. When the right support plate assembly is flipped, it is located on top of the central support frame assembly. When the right support plate assembly is unfolded, its right end is supported by the support bracket. A driver's side berth cushion is provided on top of the left berth compartment assembly, and a foldable front passenger side berth cushion is provided on top of both the central support frame assembly and the right support plate assembly.

[0006] The support bracket includes a vertical connecting part, a horizontal support part, and an inclined support part. The upper end of the vertical connecting part is hinged to the end of the horizontal support part via a first pin. One end of the inclined support part is hinged to the vertical connecting part via a second pin. The other end of the inclined support part is connected to the horizontal support part via a sliding shaft. The horizontal support part has a linear groove for the movement of the sliding shaft. A stop part is provided in the lower part of the horizontal support part. The middle part of the stop part is hinged to the horizontal support part via a third pin. When the outer end of the stop part is in a low position, its inner end is in contact with the sliding shaft.

[0007] A bedside storage box is installed on the support frame.

[0008] The right-side support plate assembly includes a sheet metal frame beam, which is assembled with a composite wood board to form a complete support. Decorative leather is pasted on the front of the composite wood board, and the back of the sheet metal frame beam is assembled with a plastic tabletop.

[0009] Two sheet metal blocks are provided on the sheet metal frame beam. When the right support plate assembly is completed, the bottom of the sheet metal blocks contacts the support bracket.

[0010] The intermediate support frame assembly and the right support plate assembly are connected by a hinge.

Detailed Implementation

[0029] The present invention will be further described below. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the scope of protection of the present invention.

[0030] Example 1

[0031] like Figures 1 to 4As shown, this invention discloses a flip-up lower berth assembly adapted to the space occupied by the front passenger seat, consisting of two parts: a three-section berth pad assembly and a berth support frame assembly. The three-section berth pad assembly includes a driver's side berth pad 6 and a front passenger side berth pad 7. The berth support frame includes a left berth box assembly 1, a middle support frame assembly 2, and a right support plate assembly 3. Specifically, the left end of the middle support frame assembly 2 is connected to the left berth box assembly 1, and the right end of the middle support frame assembly 2 is hinged to the right support plate assembly 3. A support bracket 5 is provided on the right side of the right support plate assembly 3. When the right support plate assembly 3 is flipped, it is located on top of the middle support frame assembly 2. When the right support plate assembly 3 is unfolded, its right end is supported by the support bracket 5. The driver's side berth pad 6 is provided on the left berth box assembly 1, and the foldable front passenger side berth pad 7 is provided on the middle support frame assembly 2 and the right support plate assembly 3.

[0032] The working process of this invention is as follows: the left side of the intermediate support frame assembly 2 overlaps and is fixed to the left berth compartment and the floor; the right side support plate assembly 3 unfolds, with its right side overlapping the support bracket 5; simultaneously, the passenger-side berth cushion 7 unfolds, enabling the passenger seat in scenario one to be used normally as a regular seat; the lower berth assembly functions as a sleeper bed, as shown below. Figure 13 As shown; the left side of the intermediate support frame assembly 2 overlaps and is fixed to the left berth compartment and the floor, while the right side support plate assembly 3 is folded and set on the intermediate support frame assembly 2. This, along with the folding support bracket 5, creates space. Simultaneously, the passenger-side berth cushion 7 is folded, enabling the passenger seat backrest (or the entire seat) to be adjusted backward to utilize the space in Scenario Two. Figure 14 As shown.

[0033] This invention solves the problem of space constraints when the front passenger seat backrest (or the entire seat) is adjusted backward and the sleeper berth is used by setting up an articulated flip-up sleeper berth assembly. When the seat is moved forward, the sleeper berth can be used normally. When the sleeper berth is flipped up, space is made for the front passenger seat backrest (or the entire seat) to be adjusted backward, avoiding the problem of limited adjustment range and insufficient rearward space caused by the sleeper berth behind. In this way, the comfort of the front passenger resting can be improved while ensuring the resting function of the lower sleeper berth.

[0034] Example 2

[0035] like Figures 1 to 4As shown, this invention discloses a flip-up lower berth assembly adapted to the space occupied by the front passenger seat, consisting of two parts: a three-section berth mat assembly and a berth support frame assembly. The three-section berth mat assembly includes a driver's side berth mat 6 and a front passenger side berth mat 7. The berth support frame includes a left berth box assembly 1, a middle support frame assembly 2, and a right support plate assembly 3. Specifically, the left end of the middle support frame assembly 2 is connected to the left berth box assembly 1, and the space formed by the middle support frame assembly 1 and the left berth box assembly 1 can accommodate appliances such as a refrigerator. The right end of the middle support frame assembly 2 is hinged to the right support plate assembly 3. A support bracket 5 is provided on the right side of the right support plate assembly 3. When the right support plate assembly 3 is flipped, it is located on top of the middle support frame assembly 2. When the right support plate assembly 3 is unfolded, its right end is supported by the support bracket 5. Figure 9 As shown. The right-side support plate assembly can be folded and flipped in 3-fold, and the support bracket can be folded and stored in 5-fold. It is equipped with a passenger seat, which can slide to the rear of the driver's cab to increase the space for activities and entertainment. At the same time, the seat back can be fully extended for rest.

[0036] The driver's side sleeper berth cushion 6 is installed on the left sleeper berth assembly 1, and the right end of the middle support frame assembly 2 and the right side support plate assembly 3 are equipped with a foldable passenger side sleeper berth cushion 7. The passenger side sleeper berth cushion 7 can be unfolded when in use and folded for storage, and together with the driver's side sleeper berth cushion 6, it forms the lower sleeper berth cushion assembly for the driver and passengers to rest.

[0037] A bedside storage box 4 is mounted on the support bracket 5, and the bedside storage box 4 is bolted to the support bracket 5. When the berth is unfolded, the bedside storage box 4 can be used to store mobile phones, chargers, etc. When the berth is flipped over to be used as a dining table, the bedside storage box 4 can be flipped over with the support bracket 5. The design of the bedside storage box 4 in this invention can increase storage space and facilitate the storage of daily items.

[0038] like Figures 4 to 6 As shown, the middle support frame assembly 2 and the right support plate assembly 3 are connected by a hinge 8. The right support plate assembly 3 is directly mounted on the support bracket 5, and together with the left sleeper box assembly 1, forms the sleeper support frame assembly.

[0039] like Figure 7 and Figure 8 As shown, the front of the right-side support plate assembly 3 is a support plate, which can be used as a dining table when folded and flipped, and serves as a supporting structure when unfolded. The right-side support plate assembly 3 includes a sheet metal frame beam 31, which is assembled with a composite wood board 32 to form a complete support. Decorative leather is pasted on the front of the composite wood board 32, and the back of the sheet metal frame beam 31 is assembled with a plastic tabletop surface 33. The plastic tabletop surface 33 has cup holders and a phone holder, integrating functions such as cup holders and phone holders. Figure 12 As shown, two sheet metal blocks 34 are provided on the sheet metal frame beam 31. When the right support plate assembly 3 is unfolded, the sheet metal blocks 34 directly contact the support bracket 5 when used in conjunction with the support bracket 5, so as to avoid damage to the plastic tabletop surface.

[0040] like Figure 10 As shown, the support bracket 5 includes a vertical connecting part 51, a horizontal support part 52, and an oblique support part 53. The upper end of the vertical connecting part 51 is hinged to the end of the horizontal support part 52 via a first pin 54. One end of the oblique support part 53 is hinged to the vertical connecting part 51 via a second pin 55, and the other end of the oblique support part 53 is connected to the horizontal support part 52 via a sliding shaft 56. The vertical connecting part 51, the horizontal support part 52, and the oblique support part 53 cooperate to form a triangular support structure. A linear groove 57 for the movement of the sliding shaft 56 is provided on the horizontal support part 52. A stop part 59 is provided in the lower part of the horizontal support part 52, and the middle part of the stop part 59 is hinged to the horizontal support part 52 via a third pin 58. When the outer end of the stop 59 is in the low position, its inner end contacts the sliding shaft 56, which can restrict the sliding shaft 56 from sliding in the linear groove 57, thus achieving a locking function. When it is necessary to fold the support bracket 5, pressing the stop 59 unlocks it, allowing the support bracket 5 to be folded. Figure 11 As shown. In this invention, the support bracket 5 adopts a foldable design, which can cleverly improve space utilization.

[0041] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
