[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] Combination Figure 1 to Figure 2 As shown, this embodiment provides a waterproof structure for an expansion compartment of a motorhome, which is mainly used for waterproofing and diverting between the expansion compartment and the compartment storage opening in the motorhome. Specifically, the waterproof structure in this embodiment includes a compartment storage opening 11 opened in the compartment body 1, an expansion compartment 2 sliding in and out along the compartment storage opening 11, and a waterproof component 3 arranged between the compartment storage opening 11 and the expansion compartment 2. By setting the waterproof component 3, it is possible to prevent the water-facing surface of the compartment ( Figure 2 The rainwater (in the direction indicated by the middle arrow) hits the gap between the expansion compartment 2 and the compartment storage opening 11, and then the rainwater penetrates into the compartment along the side wall of the expansion compartment 2.

[0021] Combination Figure 3 and Figure 4 As shown, the waterproof component 3 in this embodiment includes a fixing seat 31 matched with the car storage port 11, a support member 32 matched with the fixing seat 31, and a plurality of wipers 33 arranged on the side of the fixing seat 31 opposite to the outer wall of the expansion compartment 2. Preferably, the plurality of wipers 33 in this embodiment are spaced side by side and are integrally formed with the fixing seat 31 using rubber or other wear-resistant elastic materials.

[0022] In addition, in order to further improve the structural strength of the wiper blade 33 after molding and make it have better toughness, the plurality of wiper blades 33 are respectively covered with reinforcing ribs 35. In order to facilitate molding and installation, as a preference, in this embodiment, the plurality of reinforcing ribs 35 matching the corresponding wiper blades 33 can be integrally injection molded with the support member 32. During the integral molding process of the wiper blade 33 and the fixing seat 31, the support member 32 containing the plurality of reinforcing ribs 35 is integrally inserted so that it is covered in the integrally arranged fixing seat 31 and the wiper blade 33.

[0023] Furthermore, in order to further enhance the structural strength of the wiper blade 33 and reduce the friction between the lower end of the wiper blade 33 and the outer wall of the expansion chamber 2, the wall thickness of the plurality of wiper blades 33 gradually narrows downward from the end connected to the fixing seat 31.

[0024] The waterproof component 3 adopting the above-mentioned structural design, after being installed on the inner wall of the car storage opening 11, the lower ends of the multiple wipers 33 respectively abut against the outer wall of the expansion compartment 2, thereby forming multiple waterproof layers. Especially when the expansion compartment is folded up when there is water, there are multiple levels of wiping effects, thereby effectively preventing rainwater from penetrating into the car.

[0025] Furthermore, in this embodiment, in order to better improve the waterproof effect of the waterproof component 3, the plurality of wipers 33 are all inclined and the lower ends are all facing the water-facing surface of the compartment storage opening 11. That is, they are all arranged at the same inclination angle toward the side of the outer wall of the compartment. In this embodiment, in order to enable the rainwater sliding down the inclined surface of the wiper 33 to be promptly discharged outward, a water guide groove 34 is formed between the adjacent wipers 33 arranged at intervals. The water guide groove 34 is arranged along the length direction of the fixing seat 31, and a drainage port is opened on the water guide groove 34 located below the expansion compartment 2, so that the infiltrated rainwater is guided to the bottom of the expansion compartment 2 through the water guide groove 34 and discharged outward through the drainage port, so that not only a better waterproof effect can be achieved, but also a better diversion effect can be achieved for the infiltrated rainwater, and in the process of sliding in and out of the expansion compartment 2, the outer wall of the expansion compartment 2 can be effectively cleaned by the arrangement of the plurality of wipers 33 to prevent dust or foreign matter from entering the compartment.

[0026] Combination Figure 2 and Figure 3 As described, in the present embodiment, in order to facilitate the circumferential installation and fixation of the waterproof component 3 along the inner wall of the compartment storage opening 11 and facilitate the shaping of the fixing seat 31, preferably, the fixing seat 31 is provided with a slot along the length direction, the lower bottom surface of the support member 32 is bonded to the inner bottom surface of the slot, and the upper surface of the support member 32 is bonded to the installation slot opened on the inner wall of the compartment storage opening 11 by laying glue or double-sided tape 36.

[0027] Further preferably, the support member 32 is configured as a flexible member that is convenient for bending and shaping. The flexible member can be made of a material with good toughness, such as an aluminum strip or a plastic strip.

[0028] After the waterproof component 3 with the above structural design is assembled, it can be inserted into the installation groove opened along the circumferential direction on the inner wall of the compartment storage opening 11, and the installation groove is bonded to the fixing seat 31 and / or the support member 32 by glue or adhesive. It is also possible to set some snap-fit ​​structures on the above installation groove and the fixing seat 31 according to design requirements, so that the waterproof component 3 is directly snapped into the installation groove.

[0029] In addition, in order to further improve the convenience of assembly and reduce the workload of assembly, as a preference, the support member 32 in this embodiment can also be integrally formed with the fixing seat 31, that is, when the fixing seat 31 and the wiper blade 33 are integrally formed, the support member 32 is also wrapped into the fixing seat 31 so that it forms a whole with the fixing seat 31.

[0030] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
