Description

Technical Field

[0001] This utility model relates to the field of camping vehicles, and in particular to a frameless double-layer base camping vehicle that can be folded flat. Background Technology

[0002] With the rise of outdoor camping activities, the demand for campervans is also increasing. Currently, most campervans are foldable, with a bottom frame composed of multiple hinged connecting rods. Each connecting rod requires a hinge shaft at its end. To improve the load-bearing capacity of campervans, manufacturers increase the number of connecting rods on the bottom frame. However, with the increase in connecting rods, the number of hinge shafts also increases. This leads to a longer assembly time for a single bottom frame, resulting in a decrease in the overall production efficiency of the vehicle. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model proposes a frameless, double-layered, foldable camping vehicle. (See reference...) Figure 1 The device includes a bottom frame, which comprises two symmetrically arranged parallel rod groups 1 and two irregular rod groups 2, as well as several support rods 3. Each side is composed of a parallel rod group 1 and an irregular rod group 2. The support rods 3 are located between the parallel rod groups 1 and the irregular rod groups 2, and a connecting seat 4 is provided between the parallel rod groups 1 and the irregular rod groups 2 on the same side. The inner ends of the parallel rod groups 1 and the irregular rod groups 2 are rotatably connected to the connecting seat 4.

[0021] See Figure 3The parallel rod group 1 includes an upper parallel rod 11 and a lower parallel rod 12. The irregular rod group 2 includes an upper straight rod 21 and a lower irregular rod 22. The lower irregular rod 22 includes a parallel section 221 and an inwardly inclined section 222. A connecting section 223 is inclined between the parallel section 221 and the inwardly inclined section 222. The lower irregular rod 22 is generally extended in a Z-shape. The connecting seat 4 is provided with two upper hinge shafts 41 and one lower hinge shaft 42. The two upper hinge shafts 41 are preferably symmetrically arranged. The inner ends of the upper parallel rod 11 and the upper straight rod 21 extend into the connecting seat 4, and their inner ends are respectively hinged to the two upper hinge shafts 41. The inner end of the lower parallel rod 12 extends into the interior of the connecting seat 4. The inwardly inclined section 222 is located inside the connecting seat 4. The inner ends of the lower parallel rod 12 and the inwardly inclined section 222 are jointly hinged to the lower hinge shaft 42. In this product, only 6 hinge shafts are needed for the 8 poles, which can reduce the assembly time of 2 hinge shafts when assembling the bottom frame, thus improving assembly efficiency and reducing the cost of campervan accessories to a certain extent.

[0022] See Figure 3 Two symmetrical clearance grooves 43 are provided on the top surface of the connecting seat 4. The clearance grooves 43 can prevent interference between the upper parallel rod 11 and the upper straight rod 21 and the connecting seat 4 when they rotate. Several baffles 44 are provided on the upper outer side of the groove opening of the clearance groove 43. When the bottom frame is flattened, the inner ends of the upper parallel rod 11 and the upper straight rod 21 respectively abut against the baffles 44 on both sides to ensure the stability of the flattened structure of the bottom frame after loading heavy objects. At the same time, a positioning component 7 is provided between the parallel rod group and the irregular rod group. The positioning component can prevent the bottom frame from flipping upward during travel and improve the stability of the bottom frame.

[0023] See Figure 1 , 2 The bottom frame has side frames 5 on its front and rear sides respectively. Each side frame 5 includes two uprights 51 and several crossbars 52. The lower end of each upright 51 is provided with a connecting plate 53. In this embodiment, only one connecting plate 53 is provided. The outer ends of the parallel rod group 1 and the irregular rod group 2 are respectively hinged to the connecting plates 53 on both sides. The bottom surface of the connecting plate 53 is provided with a support piece 531. When the bottom frame is flattened, the outer ends of the lower parallel rod 12 and the lower irregular rod 22 abut against the support piece 531 to ensure the stability of the unfolded structure of the whole vehicle.

[0024] See Figure 1A rear door frame 6 is rotatably connected to the side frame 5 located at the rear. A positioning piece 54 is fixed to the upright 51 of the side frame 5, and the positioning piece 54 has a positioning hole 541. The rear door frame 6 has a retractable positioning post 61. The position of the rear door frame 6 and the side frame 5 is locked by the engagement of the positioning post 61 with the positioning hole 541. The rear door frame 6 is made of hollow tubing. Figure 3 As shown, the positioning post 61 is located at the end of a V-shaped spring piece. The positioning post 61 and the spring piece are hidden inside the hollow tube. The spring piece pushes the positioning post 61 outward. The hollow tube has a through hole, and the positioning post 61 extends out of the through hole.

[0025] See Figure 5 The positioning component 7 includes a positioning plate 71 and two positioning protrusions 72. In one embodiment, the positioning plate 71 is fixed to the top surface of the connecting seat 4. The two ends of the positioning plate 71 are respectively provided with positioning holes 711. The positioning protrusions 72 are provided at the inner ends of the upper parallel rod 11 and the upper straight rod 21. When the bottom frame is flattened, the positioning protrusions 72 are engaged in the positioning holes 711. The stability of the bottom frame is improved by the cooperation and positioning of the positioning plate 71 and the positioning protrusions 72.

[0026] See Figure 5 In another embodiment, the positioning component 7 also includes a positioning plate 71 and two positioning protrusions 72. The positioning protrusions 72 are located at the inner ends of the upper parallel rod 11 and the upper straight rod 21. One end of the positioning plate 71 is rotatably connected to either of the positioning protrusions 72, and the other end of the positioning plate 71 is provided with a locking hole 712. When the bottom frame is flattened, the user rotates the positioning plate 71 to engage the locking hole 712 with the other positioning protrusion 72, which also improves the stability of the bottom frame. Either of the two positioning component options can be used, or the two can be combined simultaneously.

[0027] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
