Description

Technical Field

[0001] This utility model belongs to the field of automotive parts, and in particular relates to a folding component for extending automotive space with a collision avoidance structure. Background Technology

[0002] When family SUVs and other vehicles are used for travel or overnight stays, the limited interior space and lack of basic amenities negatively impact the experience, such as the absence of shower facilities. Therefore, parking is often confined to campgrounds or parking lots with bathroom facilities, significantly reducing the convenience of overnight parking. This inconvenience is even more pronounced on long-distance trips. When driving in uninhabited areas like deserts and grasslands, or encountering prolonged highway congestion, the need for a toilet becomes a necessity. Existing SUV solutions often rely on simple portable toilets, but these suffer from installation time-consuming processes, poor privacy, and difficulties in waste disposal. Furthermore, traditional hinged hinges cannot accommodate multiple folds of various panels. There is an urgent need to develop a vehicle space extension mechanism that, when assembled into an existing vehicle, expands the interior space, providing a stable and private extra space to meet the needs of overnight travel, personal toileting, and showering. In particular, it is crucial to address the issue of the angled rear end of existing SUVs affecting the layout of the extension mechanism and to accommodate multiple folds of square or other polygonal panels.

The pair of pull rails 30 are respectively installed on the inner walls of both sides of the automotive trunk. The left folding assembly 10 and the right folding assembly 20 are symmetrical in structure. The left folding assembly 10 includes a first folding assembly 50, a second folding assembly 60, a fourth folding plate 4 and an eighth folding plate 8. The first folding assembly 50 and the second folding assembly 60 are arranged side by side in the horizontal direction and connected by flexible hinges 70. The fourth folding plate 4 and the eighth folding plate 8 are arranged side by side in the horizontal direction and connected by flexible hinges 70. The fourth folding plate 4 is located at the bottom end of the first folding assembly 50 and is connected to the first folding assembly 50 by flexible hinges 70. The eighth folding plate 8 is located at the bottom end of the second folding assembly 60.

[0047] The first folding assembly 50 includes a first folding plate 1, a second folding plate 2, and a third folding plate 3, which are connected from top to bottom by a flexible hinge 70; the bottom end of the third folding plate 3 is connected to the top end of the fourth folding plate 4 by a flexible hinge 70.

[0048] The second folding assembly 60 includes a fifth folding plate 5, a sixth folding plate 6, and a seventh folding plate 7, which are connected from top to bottom by a flexible hinge 70; the eighth folding plate 8 is located below the seventh folding plate 7, and the eighth folding plate 8 is not connected to the seventh folding plate 7.

[0049] The first folding plate 1 and the fifth folding plate 5 are side by side in the horizontal direction and are connected by a flexible hinge 70; the second folding plate 2 and the sixth folding plate 6 are side by side in the horizontal direction and are connected by a flexible hinge 70; the third folding plate 3 and the seventh folding plate 7 are side by side in the horizontal direction and are connected by a flexible hinge 70.

[0050] The four folding plates, namely the second folding plate 2, the third folding plate 3, the sixth folding plate 6, and the seventh folding plate 7, have the same vertical width. The lower left corner of the second folding plate 2 is connected to the second corner plate 21 via a flexible hinge 70. The upper left corner of the third folding plate 3 is connected to the third corner plate 31 via a flexible hinge 70.

VX42, Ultra-Light Weight Fabric (4-7D Nylon / Polyester), Silnylon (Silicone Nylon), ECOPAK TM EPLX600 recycled polyester fiber, PU coated nylon, Ripstop Nylon, Lightweight Fabric, or PVC tent fabric, etc.; folding panels and corner panels, together with flexible hinges, can be unfolded in all directions and connected to the vehicle body to protect privacy and keep warm, achieving the technical effect of folding and storing with minimal volume and presenting maximum space when expanded.

[0054] Example 1

[0055] like Figure 3-11 Since the vertical widths of the four folding plates—the second folding plate 2, the third folding plate 3, the sixth folding plate 6, and the seventh folding plate 7—are the same, in this embodiment, the vertical widths of the first folding plate 1 and the fifth folding plate 5, and the vertical widths of the fourth folding plate 4 and the eighth folding plate 8, are equal to the vertical width of the second folding plate 2. The upper left corner of the first folding plate 1 is connected to a first corner plate 11 via a flexible hinge 70, and the upper right corner of the fifth folding plate 5 is connected to a fifth corner plate 51 via a flexible hinge 70. The first corner plate 11 and the... The five-fold corner plate 51 is connected by a flexible hinge 70; the lower left corner of the fourth fold plate 4 is connected to the fourth corner plate 41 by a flexible hinge 70, and the lower right corner of the eighth fold plate 8 is connected to the eighth corner plate 81 by a flexible hinge 70. The fourth corner plate 41 and the eighth corner plate 81 are connected by a flexible hinge 70; the first corner plate 11, the second corner plate 21, the third corner plate 31, the fourth corner plate 41, the fifth corner plate 51, the sixth corner plate 61, the seventh corner plate 71 and the eighth corner plate 81 are the same size.

[0056] Example 2

[0057] In this embodiment, the vertical widths of the first folding plate 1 and the fifth folding plate 5, and the vertical widths of the fourth folding plate 4 and the eighth folding plate 8 are much smaller than the vertical width of the second folding plate 2 (the vertical widths of the four folding plates, namely the second folding plate 2, the third folding plate 3, the sixth folding plate 6 and the seventh folding plate 7, are the same). The first folding plate 1, the fifth folding plate 5, the fourth folding plate 4 and the eighth folding plate 8 can be folded without the need for corner plates.

[0058] Example 3

[0059] In this embodiment, the vertical widths of the first folding plate 1 and the fifth folding plate 5, and the fourth folding plate 4 and the eighth folding plate 8, are smaller than the vertical width of the second folding plate 2 (the vertical widths of the four folding plates, the second folding plate 2, the third folding plate 3, the sixth folding plate 6, and the seventh folding plate 7, are the same). However, the folded portions of the first folding plate 1 and the fifth folding plate 5, the fourth folding plate 4, and the eighth folding plate 8 will affect the folding of the second corner plate 21, the third corner plate 31, the seventh corner plate 71, and the sixth corner plate 61. In this embodiment, the upper left corner of the first folding plate 1 is connected to the first corner plate 11 via a flexible hinge 70, and the upper right corner of the fifth folding plate 5 is connected to the fifth corner plate 51 via a flexible hinge 70. The first corner plate 11 and the fifth corner plate 51 are connected via a flexible hinge 70. The lower left corner of the fourth folding plate 4 is connected to the fourth corner plate 41 via a flexible hinge 70, and the lower right corner of the eighth folding plate 8 is connected to the eighth corner plate 81 via a flexible hinge 70. The fourth corner plate 41 and the eighth corner plate 81 are connected via a flexible hinge 70.

[0060] In addition to the technical solutions disclosed in Embodiments 1-3 above, the position of the corner plate may vary depending on the design and folding method in actual applications. The order of the illustrations and text descriptions is only for ease of description, and the solutions are not limited to the technical solutions in Embodiments 1-3.

[0061] Example 4

[0062] A folding assembly for extending automotive space with a clearance structure also includes an L-shaped angle bracket 80 and buckles 801. The L-shaped angle bracket 80 is positioned at a vertical right angle on the inner side of the left folding assembly 10 and the right folding assembly 20. Multiple buckles 801 pass through the L-shaped angle bracket 80 and are snapped onto the left folding assembly 10 and the right folding assembly 20. Fasteners 90 are provided on the sides of the fifth folding plate 5, the sixth folding plate 6, and the seventh folding plate 7 on the left folding assembly 10 and the right folding assembly 20, as well as on the bottom edge of the fourth folding plate 4. The fasteners 90 are buttons or zippers, such as... Figure 14 The left folding assembly 10 and the right folding assembly 20 are connected by fastener 90, as shown below. Figure 12 This is a schematic diagram showing the installation of the left folding assembly 10 with the L-shaped angle bracket 80 via the snap fastener 801. The top and side edges of the first folding plate 1, the top and side edges of the fifth folding plate 5, and the sides of the second folding plate 2, the third folding plate 3, and the fourth folding plate 4 on the left folding assembly 10 are provided with extended flexible hinges 701, which overlap with the vehicle body. Because the left folding assembly 10 and the right folding assembly 20 are structurally symmetrical, the top and side edges of the first folding plate 1, the top and side edges of the fifth folding plate 5, and the sides of the second folding plate 2, the third folding plate 3, and the fourth folding plate 4 on the right folding assembly 20 are also provided with extended flexible hinges 701, allowing the right folding assembly 20 to also overlap with the vehicle body via these extended flexible hinges 701.

[0063] The L-shaped angle bracket 80 strengthens the structural strength of the left folding assembly 10 and the right folding assembly 20. To further strengthen the structural strength of the left folding assembly 10 and the right folding assembly 20, the folding plates can be designed to interlock, such as... Figure 13 The left folding assembly 10 and the right folding assembly 20 are connected by fastener 90, and the extended flexible hinge 701 is used to connect with the vehicle body, which improves the privacy performance of the extended space of the car.

[0064] Example 5

[0065] A folding assembly for extending automotive space with a clearance structure also includes a honeycomb grid panel 100, a water collection tank 110, a water pump 120, and a drain valve 130. The water collection tank 110 is placed above the fourth folding plate 4 of the unfolded left folding assembly 10 and right folding assembly 20. The honeycomb grid panel 100 is placed inside the water collection tank 110 and is used for standing. The water pump 120 is placed between the honeycomb grid panel 100 and the water collection tank 110. The drain valve 130 is located on the right side wall of the water collection tank 110. Figure 15 This allows for showering within the extended space of the car. During or after showering, the drain valve 130 can be opened to drain the water from the collection tank 110, thus enriching the product's functionality.

[0068] S1. Pull the left folding component 10 out of the trunk via the pull rail 30;

[0069] S2. Unfold the avoidance structure 40 from the panel of the second folding plate 2, and then unfold the left folding component 10 180° from the middle through the flexible hinge 70;

[0070] S3. Unfold the fifth folding plate 5 and the first folding plate 1 upwards by 180° around the flexible hinge 70 between the fifth folding plate 5 and the sixth folding plate 6; unfold the fourth folding plate 4 and the eighth folding plate 8 downwards by 90° around the flexible hinge 70 between the fourth folding plate 4 and the third folding plate 3.

[0071] S4. The eighth folding plate 8 unfolds outward around the flexible hinge 70 between the fourth folding plate 4 and the eighth folding plate 8, with an unfolding angle greater than 90°;

[0073] S6. Repeat steps S1-S5 to unfold the right-folding component 20;

[0074] S7. Connect the left folding assembly 10 and the right folding assembly 20 with fasteners 90, and overlap the extended flexible hinges 701 on the left folding assembly 10 and the right folding assembly 20 with the vehicle body; place the water collection tank 110 above the fourth folding plate 4 of the left folding assembly 10 and the right folding assembly 20, and place the honeycomb grid plate 100 inside the water collection tank 110; place the water pump between the honeycomb grid plate 100 and the water collection tank 110.
